Vehicle glass run

Technical field

The present invention relates to a kind of vehicle glass guide groove (glass run), this guide groove is installed in the inside circumference of door frame, moves down so that the guiding car door is on glass, simultaneously the space between Sealed doorframe and the automobile door glass.

Background technology

As shown in Figure 1, at the inside circumference of the doorframe 2 of car door 1 glass run 110 is installed, so that guiding automobile door glass 5 moves up and down.The cross-section structure of existing glass run is seen Fig. 2, and Fig. 2 is the cutaway view along A-A line among Fig. 1.

Need to prove that Fig. 1 and 2 is depicted as Glass (sash type) car door, this glass run also is applicable to extrusion type (press type) car door.

As shown in Figure 1, Chang Gui glass run 110 is installed in the conduit 3 of doorframe 2 usually so that guiding automobile door glass 5 moves up and down the space that seals simultaneously between automobile door glass 5 and the doorframe 2.Thereby glass run 110 links to each other on configuration with the corner part of doorframe 2 consistent with one section part by compression molding one section straight line extruding part by extrusion forming.Sealing between car door 1 and the car body is made by the weather strip of car door and/or the weather strip (not shown) of opening fringing (opening trim), wherein the weather strip of car door be installed on the door panel and the periphery frame of doorframe 2 on, the weather strip of opening fringing is installed on the edge of opening of car body.

The main body section of glass run 110 is a U-shaped, and it comprises car outside sidewall 120, car inside side walls 130 and diapire 140.It also has a car outside sealing lip 150, and this car outside sealing lip 150 is from stretching to the inside of glass run cell body U-shaped section near the front end of car outside sidewall 120.Equally, other has a car inner seal lip 160 from stretching to the inside of glass run cell body U-shaped section near the front end of car inside side walls 130.Car outside sidewall 120, car inside side walls 130 and diapire 140 plugs are in the conduit 3 of doorframe 2, and the lateral surface of these three walls contacts with the inner face of conduit 3 respectively simultaneously, and glass run 110 just is fixed on the inside circumference of doorframe 2 like this.

When slides within the U-shaped section of glass run 110 of the end of automobile door glass 5, its both sides, end are by car outside sealing lip 150 and 160 sealings of car inner seal lip and fixing (can be the Japanese documentation (the 2nd, 3 page and Fig. 2) of JP2000-25462A referring to Japanese patent application publication No. for example).But in order to ventilate, the automobile door glass 5 of vertical shifting is parked in the half of doorframe 2 sometimes.At this moment, automobile door glass 5 is not fixed by the upper end of doorframe 2, and just fixing by the glass run 110 on both sides.Therefore, automobile door glass 5 may be along its laterally (Width of vehicle) vibration.Particularly when high vehicle speeds, automobile door glass 5 can be inhaled outside car and outside car and move, perhaps automobile door glass 5 vibrates (for example being the Japanese documentation (pp.5,5 and Fig. 1 (b)) of JP2002-19473A referring to publication number) because of vehicle travels on rough road.

At this moment,, can consider car inner seal lip 160 and sealing lip 150 thickenings of the car outside and raising hardness in order to prevent displacement or vibration, thus the Clamping force of 110 pairs of automobile door glass 5 of increase glass run.Yet, if thickening, thereby the resistance of automobile door glass 5 vertical shifting also can increase make move not smooth.In addition, only be difficult in automobile door glass 5 is securely fixed in the resistance that glass run U-shaped section in-to-in can suppress automobile door glass 5 vertical shifting simultaneously again with car inner seal lip 160 and cantilever style car outside sealing lip 150, therefore automobile door glass 5 vibrations contact the front end of sealing lip 150,160 continually and separate with inside sidewalls, produce unusual noise.

If the displacement of automobile door glass 5 increases, sealing lip 150,160 can closely contact the sidewall 120,130 of glass run 110, at this moment, the antagonistic force of sealing lip 150,160 can increase, thereby prevent the further displacement of automobile door glass 5, but in the part that displacement reduces, the antagonistic force deficiency of sealing lip 150,160, thus can not prevent the displacement or the vibration of automobile door glass 5.

In addition, now considered car inner seal lip 160 and car outside sealing lip 150 is made hollow with respect to car inside side walls 130 and car outside sidewall 120, thereby fixed automobile door glass 5 by the hollow sealing lip.

Yet, when coming molded hollow sealing lip by extrusion forming, in order to prevent that hollow space from damaging by pressure because of negative pressure when carrying out extrusion forming, must continuous control be delivered in the hollow space by the air of set pressure, reduce the speed of moulding and impair capacity rating thereby molded thus work meeting becomes complicated.

Summary of the invention

Thus, one object of the present invention is to provide a kind of vehicle glass run, no matter where automobile door glass is in glass run, this glass run all can prevent automobile door glass displacement or vibration by sealing lip, fixing automobile door glass correctly, make automobile door glass vertical shifting smoothly by the sliding resistance that reduces between automobile door glass and the sealing lip, and can prevent the generation of abnormal noise.

To achieve these goals, first aspect of the present invention is a kind of vehicle glass guide groove, its inside circumference that is installed in door frame is so that guiding automobile door glass vertical shifting, this glass run has U-shaped section glass run body, this body comprises outside sidewall, inside side walls and diapire, it is characterized in that, have outside sealing lip and inner seal lip on outside sidewall and the inside side walls, these two sealing lips stretch to the inside of glass run body U-shaped section respectively, and outside sealing lip and inner seal lip form sealing between outer surface that is inserted into the intrinsic automobile door glass of glass run and inner surface; The length of inner seal lip is greater than outside sealing lip, and it comprises the inner seal lip body that stretches out from inside side walls, the fore-end that stretches out from bending part on the bending part of inner seal lip body front end and the inner seal lip, the inner seal lip structurally should make the fore-end of sealing lip contact with inside side walls when automobile door glass is inserted into the glass run body interior simultaneously; And this inside side walls has an inside side walls contact surface, thus its treated with reduce sliding resistance when the fore-end of inner seal lip contacts with inside side walls, make mobile more easy.

In a first aspect of the present invention, outside sidewall and inside side walls have outside sealing lip and inner seal lip respectively, and these sealing lips stretch to the inside of glass run body U-shaped section.The outside sealing lip and inner seal lip form sealing between the outer surface of the automobile door glass that is inserted into the glass run body interior and inner surface, simultaneously the end of automobile door glass is fixed.Therefore, just form sealing between doorframe and the automobile door glass.

The inner seal lip is longer than outside sealing lip, can be with the outer thruster of automobile door glass to car body, thus reduce the discrepancy in elevation between door outside face and the automobile door glass, reduce air resistance, form better design.The inner seal lip comprises the inner seal lip body that stretches out from inside side walls, the fore-end that stretches out from bending part on the bending part of inner seal lip body front end and the inner seal lip, and automobile door glass can be fixed by the elasticity of inner seal lip body.Because the inner seal lip contacts with automobile door glass in the kink office, therefore the area that contacts with automobile door glass is very little, can improve sealing property like this, reduces sliding resistance, makes the vertical shifting of automobile door glass more easy, and solves the problem of abnormal noise.

Also have, the fore-end that the length of inner seal lip should make the sealing lip contacts with inside side walls in automobile door glass is inserted into the glass run body time, thus, automobile door glass is inserted between inner seal lip and the outside sealing lip, and, when the direction towards inside side walls promotes the inner seal lip, the front end of this inner seal lip contacts with inside side walls immediately, produce application force, even the displacement of automobile door glass is very little, the sealing lip also can be fixed automobile door glass, thereby prevents automobile door glass Chao Chenei over-travel.The fore-end of inner seal lip can be around the bending part bending of inner seal lip, thereby absorbs the vibration of automobile door glass.

Because inside side walls has reduced sliding resistance after treatment, therefore the fore-end when the inner seal lip contacts with inside side walls, automobile door glass is inwards during sidewall direction pushing inner seal lip, make and move easily, and when the fore-end of inner seal lip contacts with inside side walls, the inner seal lip can be at an easy rate slides on treated this surface of having reduced sliding resistance, and, this inner seal lip slides in response to the vibration of automobile door glass, thereby fix automobile door glass, simultaneously, prevent from when sliding, to produce abnormal noise.

In the present invention, because the open side direction from the part that links to each other with the inside side walls bottom towards glass run body U-shaped section on the mating surfaces of inside side walls is the plane up to a section of similar inside side walls centre portion, therefore, automobile door glass is along the direction pushing inner seal lip of inside side walls, and when the fore-end of inner seal lip contacts with inside side walls, inside side walls can receive the fore-end of inner seal lip exactly, and can disturb slip regularly, inside side walls is smoothly slided the fore-end of inner seal lip, and, when automobile door glass laterally slided, inside side walls can absorb the slip of automobile door glass flexibly.

In the present invention, since on the mating surfaces of inside side walls from one near the inside side walls bosom part project into part that the bottom links to each other between be an inclined-plane, therefore, automobile door glass is the direction pushing inner seal lip of sidewall inwards, and, when the fore-end of inner seal lip contacted with inside side walls, the inner seal lip can contact with this surface with the oblique angle, and the surface that contacts with inner seal lip fore-end and the fore-end of inner seal lip just can smoothly slide like this.Displacement or vibration in response to automobile door glass, the fore-end of this inner seal lip slides smoothly, like this inner seal lip just can be exactly fixing automobile door glass, its fore-end also can contact continuously with glass run, just can prevent that thus the slip between inner seal lip fore-end and the inside side walls from producing abnormal noise.

In the present invention, since on the mating surfaces of inside side walls near the inside side walls bosom part to part that diapire links to each other be a protruding convex surface to the inside, therefore when the fore-end of inner seal lip contacted with the mating surfaces of inside side walls and slides, the inner seal lip was more level and smooth slidably to lower slider the time.

In a kind of flexible program of the present invention, because the fore-end of inner seal lip has one section can contact with the mating surfaces of inside side walls and flexible length during slip on this surface, therefore when the fore-end of inner seal lip contacts with the mating surfaces of inside side walls, thereby this inner seal lip can crooked produce elastic force, and can prevent the automobile door glass vibration with trying hard to recommend of a suitable size glass of delaying unloading.

To achieve these goals, a second aspect of the present invention is a kind of vehicle glass guide groove, its inside circumference that is installed in door frame is so that guiding automobile door glass vertical shifting, this glass run has U-shaped section glass run body, this body comprises outside sidewall, inside side walls and diapire, it is characterized in that, have outside sealing lip and inner seal lip on outside sidewall and the inside side walls, these two sealing lips stretch to the inside of glass run body U-shaped section respectively, and outside sealing lip and inner seal lip form sealing between outer surface that is inserted into the intrinsic automobile door glass of glass run and inner surface, the length of inner seal lip is greater than outside sealing lip, the inner seal lip comprises the root of the inner seal lip body that stretches out from inside side walls and the fore-end of the inner seal lip that stretches out from inner seal lip root, the thickness of inner seal lip root is greater than the thickness of fore-end, connecting bridge between root and the fore-end forms the bending part of inner seal lip, in order to become a curved point, the variation in thickness of bending part is greater than the variation in thickness of other parts.

Because the inner seal lip comprises the root of the inner seal lip that stretches out from inside side walls and the fore-end of the inner seal lip that stretches out from inner seal lip root, can the thickness or the shape of inner seal lip root side and front be changed, thereby provide suitable bed knife and sealing force in response to the automobile door glass that is changed to of automobile door glass in glass run.

Because the thickness of inner seal lip root is greater than the thickness of fore-end, if therefore the displacement of automobile door glass in glass run is very little, this root just is difficult to distortion, the root of inner seal lip just can be fixed on the pre-position with the fore-end of inner seal lip like this, and can have stable sealing force and bed knife.When the automobile door glass displacement was very big, the root of inner seal lip was out of shape with fore-end, had enough antagonistic forces corresponding to this displacement root simultaneously.

The fore-end that this inner seal lip comprises the root of inner seal lip and stretches to glass run body U-shaped section in-to-in inner seal lip from root along its bearing of trend in an identical manner.Therefore, the section of this inner seal lip is sheet shape or arc, and the outside face that its surface particularly contacts with automobile door glass is because root and fore-end are level and smooth, and the automobile door glass slip is more easy like this.

In addition, because the connecting bridge between inner seal lip root and its fore-end is the bending part of inner seal lip, therefore in order to form a curved point, the variation in thickness of bending part is greater than the variation in thickness of other parts, and when automobile door glass contacts with glass run, and during glass run pushing inner seal lip, this inner seal lip is accurately crooked around the bending part of sealing lip.Therefore,, also can predetermined thrust pressure be added on the automobile door glass, thereby can fix automobile door glass, guarantee sealing force by means of the distortion of inner seal lip bending part even when the displacement of automobile door glass changes a little.Antagonistic force and sliding resistance to automobile door glass all can not increase sharply simultaneously.The fore-end of the inner seal lip folding part of can going for a stroll is divided crookedly, and sealing lip can absorb the vibration of automobile door glass like this.

In a kind of distortion of second aspect present invention, because the thickness of inner seal lip root is almost constant and be almost straight shape, therefore even the fore-end at the inner seal lip is pushed by automobile door glass, thus the root of sealing lip also less deformed the fore-end of inner seal lip is fixed.In addition, if the displacement of automobile door glass is very big, root can be progressively crooked after the distortion of inner seal lip bending part, and owing to curved point can progressively move towards the direction that connects root from the front end of root, therefore in response to the displacement of automobile door glass, antagonistic force can remain unchanged.

Because the forward more book more of fore-end of inner seal lip, even therefore go for a stroll the folding part when dividing distortion when sealing lip as mentioned above, the sealing lip also can contact with the automobile door glass flexibility along described surface, thereby can guarantee that sealing property also can absorb the vibration of automobile door glass.

In the another kind distortion of second aspect present invention, because the root of inner seal lip is recessed slightly to the inside crooked, and the centre portion of root is simultaneously thicker than anterior part again than two ends book, even therefore the displacement of automobile door glass is very little, thereby the bending part of inner seal lip also can crookedly can be added to predetermined antagonistic force on the automobile door glass and prevent the automobile door glass vibration.In addition, when the displacement of automobile door glass very big, and after the bending part bending of inner seal lip, if the sealing lip is further crooked, so because the centre portion of sealing lip root can be crooked, therefore just the two-stage curve of loads be can form, the displacement and the vibration of automobile door glass so just can be absorbed effectively.

In order to address the above problem, a third aspect of the present invention is a kind of vehicle glass guide groove, its inside circumference that is installed in door frame is so that guiding automobile door glass vertical shifting, this glass run has the glass run body of U-shaped section, this body comprises outside sidewall, inside side walls and diapire, it is characterized in that, have outside sealing lip and inner seal lip on outside sidewall and the inside side walls, these two sealing lips stretch to the inside of glass run body U-shaped section respectively, and outside sealing lip and inner seal lip form sealing between outer surface that is inserted into the intrinsic automobile door glass of glass run and inner surface, and having one, inboard to extend lip crooked and stretch out towards inside side walls from the front end of inner seal lip, this inboard extend lip in shape with convex towards the inside side walls bending.

Owing to inboard extend lip inwards the direction of sidewall be crooked and stretch out from the front end of inner seal lip, and should the inboard extend lip at shape epirelief sidewall to the inside, just can pass through inner seal lip, inboard lip and the hollow part of inside side walls formation triangle of extending thus, so that absorb the vibration that automobile door glass produced in the driving process.

In addition, the inner seal lip is at its front end, and the promptly inboard lip that extends can form line with automobile door glass from the part of inner seal lip front end bending and contacts, and so just can make automobile door glass vertical shifting smoothly.

Because the inboard lip that extends is at shape epirelief sidewall to the inside, therefore when automobile door glass pushing inner seal lip, thereby inboard extend lip just be easy to can crooked absorption automobile door glass vibration.

In addition, in a third aspect of the present invention, because the shape of inner seal lip makes when automobile door glass is arranged in the glass run body, the inboard front end that extends lip contacts with diapire, therefore when automobile door glass and inner seal lipped joint touch, the inboard front end that extends lip will be supported by diapire, and inner seal lip, inboard extension lip and inside side walls just form the hollow part of triangle.Like this, automobile door glass just can be fixed by triangle is hollow partially stabilizedly, and absorbs the vibration of automobile door glass.

In order to address the above problem, a kind of distortion of third aspect present invention is a kind of vehicle glass guide groove, its inside circumference that is installed in door frame is so that guiding automobile door glass vertical shifting, this glass run has the glass run body of U-shaped section, this body comprises outside sidewall, inside side walls and diapire, it is characterized in that, have outside sealing lip and inner seal lip on outside sidewall and the inside side walls, these two sealing lips stretch to the inside of glass run body U-shaped section respectively, and outside sealing lip and inner seal lip form sealing between outer surface that is inserted into the intrinsic automobile door glass of glass run and inner surface; And there have an outside to extend lip to be crooked and stretch out towards the direction of outside sidewall from the front end of outside sealing lip, has one inboardly to extend lip inwards the direction of sidewall is crooked and stretch out from the front end of inner seal lip; And lip is extended in this outside and the inboard lip that extends is being distinguished protruding sidewall laterally and inside side walls in shape.

Because it is crooked and stretch out towards the direction of outside sidewall from the front end of outside sealing lip that lip is extended in the outside, thus when automobile door glass contacts with outside sealing lip, the front end that lip is extended in the outside just contacts with the inner face of outside sidewall, and the front end of support outside sealing lip, the front end of outside extension lip just can be supported on the automobile door glass like this.

Owing to inboard extend lip inwards the direction of sidewall be crooked and stretch out from the front end of inner seal lip, thus when automobile door glass and inner seal lipped joint touch, similar to outside extension lip, the inboard front end that extends lip just contacts with the inner face of diapire, and the front end that should the inboard extends lip can be supported by diapire, thus just by the inner seal lip, inboard extend lip and inside side walls has formed a subtriangular hollow part, thereby so automobile door glass can be firmly fixed by the hollow part of triangle and fix the inner seal lip.

Similarly, automobile door glass is fixed by the front end of the front end of inner seal lip and outside sealing lip.Just can absorb the vibration of automobile door glass thus.

When extrusion forming, because the front end and the outside sidewall difference of outside extension lip are molded, inboard simultaneously front end and inside side walls of extending lip also separated shaping, therefore needn't form hollow space, and extrusion forming is more easy, thereby improves moulding speed and capacity rating.

The specific embodiment

To describe the first embodiment of the present invention based on Fig. 1,3-5 below.Fig. 1 is the lateral plan of car door.As shown in the figure, car door 1 top is equipped with doorframe 2 so that vertical shifting automobile door glass 5.That is to say at the inside circumference of doorframe 2 conduit 3 is arranged, 5 vertical shifting seal automobile door glass 5 and doorframe 2 simultaneously thereby it is used for installing glass run 10A guiding automobile door glass.

Glass run 10A comprises one section one section part by the connection extrusion forming part of compression molding of the partial sum that is essentially straight line by extrusion forming.This extrusion forming partly comprises: a part that links to each other with doorframe 2 tops, a part that links to each other with doorframe 2 back vertical side edge, and a part that links to each other with vertical side edge before the doorframe 2.The compression molding part partly links to each other these extrusion formings, thereby corresponding to constitute the part that can be installed to doorframe 2 bights with doorframe 2 in shape.

When Fig. 3 is installed to doorframe 2 vertical side edge for extruder member among Fig. 1 along the cutaway view of A-A line.Fig. 5 is the cutaway view along the A-A line among Fig. 1, and wherein, glass run 10A is installed on the doorframe 2.Glass run body 11 comprises car outside sidewall 20, car inside side walls 30 and diapire 40, and its section is U-shaped substantially.Car inner seal lip 60 extends towards the inside of the glass run body 11 of U-shaped section from the leading section of car inside side walls 30.Car inside cover lip 31 extends towards the direction of car inboard.Car outside sealing lip 50 extends towards the inside of the glass run body 11 of U-shaped section from the leading section of car outside sidewall 20.Car outboard cover lip 21 extends towards the direction in the car outside from the leading section of car outside sidewall 20.

As shown in Figure 5, when glass run 10A is installed on the conduit 3 of doorframe 2, the car inside side walls of conduit 3 is inserted in the groove 34 of the car inside side walls between car inside side walls 30 outsides and car inside cover lip 31 inboards, simultaneously, the car outside sidewall of conduit 3 is inserted in the groove 24 of the car outside sidewall between car sidewall 20 outsides, the outside and car outboard cover lip 21 inboards, like this, the front end of conduit 3 just is covered, and glass run 10A is fixed.When glass run 10A was installed on the conduit 3, the lateral surface of car outside sidewall 20, car inside side walls 30 and diapire 40 contacted also support glass guide groove 10A firmly with the medial surface of conduit 3.

Car inner seal lip 60 has: car inner seal lip body 61, bending part 62 and fore-end 63, wherein body 61 stretches out towards the inside of U-shaped section from the front end of car inside side walls 30, bending part 62 wherein bends towards diapire 40 from the front end of body 61, or the direction bending that links to each other with diapire 40 towards car inside side walls 30, wherein the fore-end 63 that extends out from bending part 62 is longer than the fore-end of routine, that is to say, when automobile door glass and car inner seal lipped joint touched, fore-end 63 extended to the length that can contact the car inside side walls from bending part 62.

Should form the length of the fore-end 63 of car inner seal lip, so that this segment length can be along curved when fore-end 63 contacts with the mating surfaces 32 of car inside side walls and slide on this surface.Therefore, when fore-end 63 contacted with mating surfaces 32, it is crooked also to produce elastic force, thereby car inner seal lip 60 prevents that with suitable the trying hard to recommend glass 5 of delaying unloading automobile door glass 5 from producing vibration.

Because car inner seal lip body 61 is longer and thicker than car outside sealing lip 50 on section, therefore automobile door glass 5 can be near car outside sidewall 20 in the U-shaped section of glass run body 11, promptly near the doorframe 2 outside the car, thereby reduce the discrepancy in elevation of car outer surface between automobile door glass 5 and the doorframe 2, and minimizing air resistance, the car body outside face is more level and smooth like this, and outward appearance is better.

The section of car inner seal lip body 61 is straight shape, perhaps omit dimpling to automobile door glass 5, therefore move up when its front end being contacted with car inner seal lip body 61 also slide thereon when automobile door glass 5, its as shown in Figure 5 elastic bending and enter into car inner seal lip 60 and car outside between the sealing lip 50.As described later, on car inner seal lip body 61 and part that automobile door glass 5 contacts, the parts that friction coefficient is very low are arranged, it is used for reducing sliding resistance.The length direction of the inside face upper edge car inner seal lip of car inner seal lip body 61 is provided with a groove 65, and this groove 65 can be used to increase the flexibility of car inner seal lip body 61.

The front end of car inner seal lip body 61 has car inner seal lip bending part 62, the direction bending that it bends towards diapire 40 or links to each other with diapire 40 along car inside side walls 30.When automobile door glass 5 contacts and enters into the inside of U-shaped section with car inner seal lip 60, as shown in Figure 5, automobile door glass 5 contacts with the bending part 62 of car inner seal lip, therefore owing to very little with the area of contact of automobile door glass 5, therefore can reduce sliding resistance to guarantee sealing.

When automobile door glass 5 when the bending part 62 of car inner seal lip contacts with car inner seal lip 60, the fore-end 63 of car inner seal lip towards the direction of diapire 40 or along the direction of the diapire 40 that connects car inside side walls 30 from the length extension of bending part 62 contact with car inside side walls 30.When automobile door glass 5 inserted U-shaped section in-to-in desired locations, the length of the fore-end 63 of car inner seal lip can make its front end contact with the inner face of car inside side walls 30 or separate slightly from the inner face of car inside side walls 30.When automobile door glass 5 displacement or when vibration a little, the fore-end 63 of car inner seal lip contacts at the inner face of its front end with car inside side walls 30, and promptly the inner face with the U-shaped section contacts.Therefore, just produce antagonistic force between the fore-end 63 of car inner seal lip and the car inside side walls 30, thereby can support, and prevent the displacement of automobile door glass 5 distortion of car inner seal lip fore-end 63.

If the length section of car inner seal lip fore-end 63 is determined to be in that fore-end 63 contacts with the mating surfaces 32 of car inside side walls and can be crooked when sliding on this surface, then fore-end 63 can be bent and slide smoothly on mating surfaces 32.

In the embodiments of figure 3, have the treated surface that can reduce the sliding resistance on the car inside side walls mating surfaces 32 (contacting) on the car inside side walls 30 that fore-end 63 is contacted with fore-end 63, mating surfaces 32 along the opening direction of U-shaped section promptly before extreme direction before half of car inside side walls 30, be shaped as straight and thicker.

Because the mating surfaces 32 of car inside side walls is a flat face, so there is nothing concavo-convex on it and when the fore-end 63 of car inner seal lip contacts with mating surfaces 32, can catches on fore-end 63.In addition, owing to carried out handling on the mating surfaces 32 of car inside side walls reducing the sliding resistance on it, so fore-end 63 is easy to just to slide and can suppresses the vibration or the displacement of automobile door glass 5.In addition, if carry out same processing at the front end of car inner seal lip fore-end, fore-end 63 is easy to slide on mating surfaces 32 and also can suppresses the vibration or the displacement of automobile door glass 5.When the front end of car inner seal lip 60 carried out same processing, sliding resistance can further reduce.

When the mating surfaces 32 of car inside side walls is configured as curved surface, and this curved surface is at the inboard convex surface that forms of car, this convex surface be arranged near the centre portion of car inside side walls 30 inner faces and and diapire 40 bonded assemblys part between the time, the fore-end 63 of car inner seal lip can slide when side shifting downwards more smoothly.

Car outside sealing lip 50 stretches to the inside of the U-shaped section of glass run body 11 from the front end of car outside sidewall 20, and car outboard cover lip 21 extends to the outside of car at the front end of car outside sidewall 20 simultaneously.The car of conduit 3 outside sidewall is inserted in the groove 24 by the formed car of the inside face outside sidewall of the outside face of car outside sidewall 20 and car outboard cover lip 21, thereby fixes glass run 10A.Car outside sealing lip 50 is arranged on the front end inboard of car outside sidewall 20 integratedly.The shape of car outside sealing lip 50 is roughly sheet, and its section is compared shorter and book more with car inner seal lip 60.Since car outside sealing lip 50 be shorter in length than car inner seal lip 60, therefore automobile door glass 5 can be more near doorframe 2 in the inside of the U-shaped section of glass run 10A, thereby reduce the discrepancy in elevation between automobile door glass 5 and the doorframe 2, reduce air resistance, thereby make the outside face of car body Paint Gloss, attractive in appearance.

As mentioned above, to handle on the mating surfaces 32 of car inside side walls 30 to reduce sliding resistance, it also is suitable below handling: add a low friction member on the surface of contact surface, perhaps low friction member of extruding simultaneously and glass run 10A are to form low friction member on this surface.So long as low-friction material, all can be used for low friction member, adhesive-bonded fabric, polythene strip, polyurethane coating or the silicone resin sheet that for example can use the TPO sheet, make by fluorine resin.Except the mating surfaces 32 of above-mentioned car inside side walls, on the fore-end 63 of car outside sealing lip 50, car inner seal lip 60 and car inner seal lip, also preferably handle to reduce sliding resistance.

Second embodiment

Based on Fig. 4 and 6 second embodiment is described below.Fig. 6 is installed on the conduit 3 of doorframe 2 for glass run 10B after along the section-drawing of Figure 1A-A line.Different mating surfaces 32 and the car inner seal lip bodies 61 that are the car inside side walls 30 of glass run 10B of second embodiment and first embodiment, other parts are similar.Therefore, the explanation of other parts is all omitted outside mating surfaces 32 and the car inner seal lip body 61.Mating surfaces 32 has a car inside side walls projection 33 near the middle part of car inside side walls 30 inner faces.Be formed on the curved surface of similar arc on the section continuously to diapire 40 from this projection 33.

Therefore, when automobile door glass 5 was inserted into the U-shaped section in-to-in pre-position of glass run 10B, the fore-end 63 of car inner seal lip had the inclined-plane of the car inside side walls projection 33 that can contact car inside side walls 30 inner faces or the length of separating a little with it.When automobile door glass 5 displacement or when vibration slightly, the front end of car inner seal lip fore-end 63 just contact with this inclined-plane of car inside side walls 30, and promptly the dip plane with bending of similar arc ground on section and the 40 continuous formation from projection 33 to diapire contact.Therefore just produce antagonistic force between the fore-end 63 of car inner seal lip and the car inside side walls 30, thereby the distortion of energy supported cart inner seal lip prevents the displacement of automobile door glass 5.At this moment, the fore-end 63 of car inner seal lip contacts with inclined-plane crooked in the U-shaped section, thus by means of with the contacting and certain angle of this inclined-plane, just can make slip more level and smooth, more easy to the absorption of the displacement of automobile door glass 5 or vibration.

The body 61 of car inner seal lip 60 has the enhancing part 64 of thickening near linking to each other with car inside side walls 30.Therefore, when automobile door glass 5 when move in the desired location, thereby it can make sealing lip 60 distortion towards the direction pushing car inner seal lip 60 of car inside side walls 30, if the shift length of automobile door glass 5 is very short, the fore-end 63 and the bending part 62 of car inner seal lip 60 can easily be bent.When the displacement of automobile door glass 5 very big, when its miles of relative movement in glass run 10B is very long, sealing lip can be deformed to the root of car inner seal lip body 61, but increase owing to keep the power of automobile door glass 5 to strengthen part 64 because of the thickening of car inner seal lip, just can prevent that therefore the displacement of automobile door glass 5 from becoming big.

The production method of glass run 10B of the present invention is described below.At first form the extruder member of glass run 10B with a kind of pliable solid material.When extrusion forming, thus glass run 10B fore-end slightly opening form under the condition of U-shaped section opening roughly and be shaped.Thus, when glass run 10B is installed on the conduit 3, squeese pressure acts on the sidewall of conduit 3, is easy to the low friction means coating on car outside sidewall 20, car inside side walls 30, diapire 40, car outside sealing lip 50 and the car inner seal lip is further processed.

Concerning formed material, can use following material: neoprene, thermoplastic elastomer or soft synthetic resin, for neoprene, for example can use EPDM rubber, for thermoplastic elastomer, for example polyolefin-based elastic body can be used, concerning soft synthetic resin, for example soft vinyl chloride etc. can be used.Adopting under the elastomeric situation, behind extrusion forming, need be sent to the sulfuration chamber, and heat neoprene with hot blast or high frequency therein.Thermoplastic elastomer and soft synthetic resin are cut into predetermined size behind cooling curing, finish the preparation of extruder member thus.

The preparation of moulding part the two ends of the above-mentioned extruder member of making need be fixed between the forming die so that the shaping extruder member, and solid material is injected in the die cavity of forming die.The section shape of the moulding part that is formed by mould is the same with extruder member almost.Preferably adopted quality and the material identical materials that is used for extrusion forming by the material of moulding.Neoprene is injected in the mould and by heating mould vulcanizes.At this moment, because extruder member bonds together by sulfuration with the parts that are formed, therefore adopt identical or same type of material can make these parts be solidified togather.Thermoplastic elastomer and soft synthetic resin melted in when cast, thus extruder member just with moulding part with regard to welding in one.The 3rd embodiment

Based on Fig. 7 and 9 the 3rd embodiment is described below.

Figure 7 shows that the section-drawing of the extruder member that will be installed to doorframe 2 vertical side edge.

Car inner seal lip 60 is near the inside of the U-shaped section that stretches to glass run body 11 front end of car inside side walls 30.Car inside cover lip 31 front ends in car inside side walls 30 reach the inboard of car.

Car outside sealing lip 50 is from stretching to the inside of the U-shaped section of glass run body 11 near the front end of car outside sidewall 20.Car outboard cover lip 21 reaches the outside of car at the front end of car outside sidewall 20.

As shown in Figure 9, when glass run 10C is installed on the conduit 3 of doorframe 2, the car inside side walls of conduit 3 is inserted in the groove 34 of the car inside side walls between car inside side walls 30 lateral surfaces and car inside cover lip 31 medial surfaces, the car of conduit 3 outside sidewall is inserted in the groove 24 of the car outside sidewall between car outside sidewall 20 lateral surfaces and car outboard cover lip 21 medial surfaces simultaneously, thereby the front end of conduit 3 is covered and support glass guide groove 10C.When glass run 10C was installed on the conduit 3, the lateral surface of car outside sidewall 20, car inside side walls 30 and diapire 40 contacted also support glass guide groove 10C firmly respectively with the medial surface of conduit 3.

Car inner seal lip 60 is longer and thick than car outside sealing lip 50, therefore as shown in Figure 9, the outside of the more close vehicle in position of automobile door glass 5, therefore the discrepancy in elevation of outside face of looking from the outside of car door 1 and automobile door glass 5 is minimized, thereby reduced sound of the wind and the air resistance in the driving process, the outward appearance of car body also designs more good-lookingly like this.

Particularly, if make the glass run 10C that installs on doorframe 2 vertical side edge have the car inner seal lip 60 of shape of the present invention at least, be parked in a half of doorframe 2 so when automobile door glass 5, when promptly half-open, automobile door glass 5 just can be fixed on the vertical side edge and prevent its displacement or vibration.

The sealing lip 60 of car inboard comprises the root 61 and the fore-end 62 of car inner seal lip, wherein root 61 extends towards the inside of the U-shaped section of glass run body 11 from car inside side walls 30, and wherein fore-end 62 stretches to the inside of the U-shaped section of glass run body 11 along its bearing of trend from the root 61 of car inner seal lip.Therefore, the section shape of car inner seal lip 60 is sheet shape or arc, and level and smooth because of root 61 and fore-end 62 with the contacted outside face of automobile door glass, automobile door glass is easy to slip like this.

The root 61 of car inner seal lip extends to the place of the only about half of length of car inner seal lip 60, and about the same from car inside side walls 30 its thickness of beginning, and this thickness is greater than the thickness of car inner seal lip fore-end 62 in addition.Therefore even when automobile door glass 5 pushing fore-ends 62, because body 61 is thicker, so fore-end 62 distortion are very little and just in the bending part 64 places bending of as described later car inner seal lip.Even when automobile door glass 5 distortion was very little, the antagonistic force that automobile door glass 5 also can be scheduled supported, and at automobile door glass 5 slightly during displacement, root 61 is also indeformable, so the fore-end 62 of car inner seal lip just is supported on the desired location.

In addition, if the displacement of automobile door glass 5 in glass run 10C becomes big, so when car inner seal lip 60 after bending part 64 places distortion, the root 61 of car inner seal lip is crooked lentamente, because the thickness of root 61 is almost constant, therefore its point of inflection can move to root from the front end of root 61, thereby in response to the displacement of automobile door glass 5, the antagonistic force that supports automobile door glass 5 is remained unchanged.

The fore-end 62 of car inner seal lip 60 forms at the only about half of length place of car inner seal lip 60, and the closer to front end, its thickness is more little.Therefore, when automobile door glass 5 contacts with the fore-end 62 of sealing lip, and as described later, when sealing lip 60 is out of shape at bending part 64 places, sealing lip can contact with automobile door glass flexibly along its surface, thereby guarantees sealing property and absorb the vibration of automobile door glass.

The root 61 of car inner seal lip and the connecting bridge between its fore-end 62 are made into the inboard bending part 64 of car, in order to form curved point when automobile door glass 5 contacts with sealing lip 60, the variation in thickness of bending part is greater than the variation in thickness of sealing lip 60 other parts.As shown in Figure 7, at the inner face of bending part 64, thickness becomes book along curve.

Because the sectional thickness at bending part 64 places of sealing lip reduces fast along curve, therefore when automobile door glass 5 contacts with glass run 10C and pushes sealing lip 60, stress is concentrated on the bending part 64 of car inner seal lip, sealing lip 60 is stable crooked, even therefore when the displacement of automobile door glass 5 changes, be displaced at automobile door glass before root 61 places of car inner seal lip, can predetermined thrust pressure be added on the automobile door glass 5 by the bending of bending part 64, thereby sealing force can be held, and the sliding resistance of automobile door glass 5 can not increase simultaneously.Because the fore-end 62 of sealing lip can be out of shape by the bending of bending part 64, so its vibration that can closely contact automobile door glass 5 and absorb automobile door glass 5.

The root 61 of car inner seal lip is straight section, perhaps omit dimpling to automobile door glass 5, therefore working as automobile door glass 5 moves up, when its front end contacts with root 61, as shown in Figure 6, its elastic bending is also slided on the surface of car inner seal lip root 61, is inserted into the inside of glass run body 11 then, and can enter between car inner seal lip 60 and the car outside sealing lip 50.In car inner seal lip 60 and the part that car outside sealing lip 50 contacts, add a low friction member as described later, slip can be carried out smoothly like this.

Car outside sealing lip 50 stretches to the inside of the U-shaped section of glass run body 11 from the front end of car outside sidewall 20, and car outboard cover lip 21 reaches the outside of car at the front end of car outside sidewall 20 simultaneously.The car outside sidewall of conduit 3 is inserted in the groove 24 of the car outside sidewall between car outside sidewall 20 lateral surfaces and car outboard cover lip 21 medial surfaces, and like this, glass run 10C just is fixed.Car outside sealing lip 50 is arranged on the front end inboard of car outside sidewall 20 integratedly.

The shape of car outside sealing lip 50 is close to and is sheet shape or the bigger arc of radius of curvature, it is than the shorter also book more of car inner seal lip 60, can make the outside of automobile door glass 5 like this at the close doorframe 2 in the inside of the U-shaped section of glass run body 11, thereby reduce the discrepancy in elevation of automobile door glass 5 and doorframe 2, reduce air cutting noise and air resistance, the outward appearance of car body is more smoothly attractive in appearance simultaneously.

The 4th embodiment

Based on Fig. 8 and 10 fourth embodiment of the invention is described below.Fig. 8 is the section-drawing along the glass run 10D of A-A line among Fig. 1.Figure 10 for glass run 10D be installed in the doorframe 2 on the conduit 3 after along the section-drawing of A-A line glass run 10D among Fig. 1.The different shapes that are car inner seal lip 60 of the 4th embodiment and first embodiment, other parts are all identical.Therefore, the explanation of other parts is all omitted outside the car inner seal lip 60.

This car inner seal lip 60 comprises the root 61 and the fore-end 62 thereof of car inner seal lip, wherein extend the inside of root 61 U-shaped section towards glass run body 11 from car inside side walls 30, and wherein fore-end 62 stretches to the inside of the U-shaped section of glass run body 11 along its bearing of trend from the root 61 of car inner seal lip.Therefore, the section shape of car inner seal lip 60 is sheet shape or arc, and itself and the contacted outside face of automobile door glass are level and smooth because of root 61 and fore-end 62, and automobile door glass is easy to just can slide like this.

Because the medial surface of the root 61 of car inner seal lip 60 bends to concave surface slightly, and the centre portion 61b book of root is in two ends, promptly want book with the part that car inner seal lip fore-end 62 links to each other than the partial sum that links to each other with car inside side walls 30, arch section 62b than car inner seal lip front end is thick simultaneously, and arch section 62b wherein bends to concave surface slightly in the inboard of car inner seal lip fore-end 62.Therefore, when automobile door glass 5 displacements are big, after bending part 64 bendings of car inner seal lip, if sealing lip is further crooked, because the centre portion 61b of sealing lip root can be crooked, therefore the loading of the centre portion 61b of loading by crooked car inner seal lip bending part 64 and crooked car inner seal lip root just can obtain the two-stage curve of loads, and the displacement of automobile door glass just can effectively be absorbed with vibrating like this.

The inboard of the fore-end 62 of car inner seal lip 60 bends to concave surface slightly.Therefore, at the part place that links to each other with car inner seal lip bending part 64, its thickness can change fast, and bending part 64 is just crooked easily like this.When fore-end 62 contacts with glass run 10D, be easy to just the surface of fore-end 62 to be shifted onto the surface of glass run 10D, thereby can guarantee sealing property.

In addition, car inner seal lip bends to form projection 63 to car inside side walls 30 from its fore-end 62.Therefore, thereby when automobile door glass 5 displacements are pushed car inner seal lip 60 to car inside side walls 30 greatly, thereby projection 63 just contacts the distortion of energy supported cart inner seal lip 60 and prevents automobile door glass 5 further displacements with car inside side walls 30.Projection 63 is as the vibration of a cushion rubber with absorption automobile door glass 5.In addition, because sealing lip 60 is not to stick to tightly on the car inside side walls 30, therefore can not produce when sealing lip 60 and car inside side walls 30 caused abnormal noise when tight coherent condition is separated.Explanation is in passing, and the surface of projection 63 and sidewall 30 is carried out processing to reduce sliding resistance.

Based on Figure 11 to 14 the 5th embodiment and the 6th embodiment are described below.

The 5th embodiment

To Figure 14 the 5th embodiment is described based on Figure 11 below.Explanation is in passing, although the state after this glass run is installed is identical with fwd embodiment, opposite with Fig. 3 etc. outside the car inboard among these figure/car.

The glass run 10E of present embodiment also has the U-shaped section, and it has glass run body 11, and this body comprises car outside sidewall 20, car inside side walls 30 and diapire 40.Car inner seal lip 60 extends towards the inside of the U-shaped section of glass run body 11 from the front end of car inside side walls 30.Car inside cover lip 31 extends towards the direction of car inboard at the front end of car inside side walls 30.Car outside sealing lip 50 extends towards the inside of the U-shaped section of glass run body 11 from the front end of car outside sidewall 20.Car outboard cover lip 21 extends towards the direction in the car outside at the front end of car outside sidewall 20.

As shown in figure 12, when glass run 10E was installed on the conduit 3 of doorframe 2, the inboard of conduit 3 contacted with the inboard fixed projection 32 of the car of car inside side walls 30.The inboard fixedly lip 33 of car inside cover lip 31 and car is used for fixing the car inside side walls of conduit 3, connects car inside side walls 30, forms sealing simultaneously between glass run 10E and conduit 3.

The outer side contacts of the inner face of conduit 3 outside sidewalls and car outside sidewall 20.The car outboard cover lip 21 and first car outside fixedly lip 22 are used for supporting the car outside sidewall of conduit 3, and connect car outside sidewall 20.Simultaneously, fixedly lip 23 formation sealing between glass run 10E and conduit 3 when the medial surface with conduit 3 contacts of second car outside.

When glass run 10E was installed on the conduit 3, car outside sidewall 20, car inside side walls 30 and diapire 40 constituted the U-shaped sections, and the lateral surface of this U-shaped section contacts with the medial surface of conduit 3, so just can stably keep glass run 10E.

Car inner seal lip 60 extends towards the inside of glass run body 11U shape section from the front end of car inside side walls 30.In car inner seal lip 60, partly locate to be provided with a part than book with the inboard bonded assembly of car inside side walls 30.This part than book has been arranged, and car inner seal lip 60 is easy to bending.Be provided with low sliding part continuously on the surface of car inner seal lip 60 and car inside cover lip 61, thereby form the low friction face 61 of car inner seal lip.In the embodiment of Figure 11 and 12, as described later, the low friction face 61 of car inner seal lip is harder than the material that constitutes glass run body 11.

The inboard extension of car lip 65 stretches out from the front end of car inner seal lip 60.The inboard extension of this car lip 65 bends towards car inside side walls 30 from the front end of car inner seal lip 60, and turn of bilge wherein forms the bending part 62 of car inner seal lip.The inboard lip 65 integrally bending cambers that extend of car form convex surface towards car inside side walls 30.Determine the inboard length of extending lip 65 of car, so that in the end of automobile door glass 5 enters glass run body 11 time, even when automobile door glass 5 vibrates car outside most external, the inboard extension of car lip 65 also can touch the boundary part between car inside side walls 30 and the diapire 40.Thus, when automobile door glass 5 was inserted in the glass run body 11, car inner seal lip 60, car inboard extension lip 65 and car inside side walls 30 just can form leg-of-mutton hollow part definitely.

When automobile door glass 5 is inserted into the inside of glass run body 11, the summit of the hollow part of triangle, promptly the bending part 62 of car inner seal lip contacts with the side formation line of automobile door glass 5, thereby forms sealing between automobile door glass 5 and glass run 10E.Thus, automobile door glass 5 just can move up and down smoothly.In addition, as mentioned above, because the surface of car inner seal lip 60 is provided with low friction member, so automobile door glass just can more easily move up and down.

Similarly, also have low friction member at the inboard position of extending lip 65 front end moving contacts of inboard, car of car inside side walls 30.Therefore, the inboard front end that extends lip 65 of car just can slide smoothly.

Because the inboard lip 65 that extends of car is than car inner seal lip 60 books, and it is protruding in car inside side walls 30, even therefore when automobile door glass 5 vibrations, thereby car inboard extend lip 65 also can be easily crooked and distortion absorb vibration.In addition, extend lip 65 and car inside side walls 30 can form the hollow part of triangle definitely because car inner seal lip 60, car are inboard, thereby so the hollow part elastically deformable of this triangle guarantee the fixedly power of being scheduled to of automobile door glass 5.In addition, when automobile door glass 5 inserted, the inboard lip 65 that extends of car contacted with diapire 40 with car inside side walls 30, so it can not separate from car inside side walls 30, thereby can not produce the abnormal noise that occurs because of separately.

As shown in figure 12, automobile door glass 5 reduces with the discrepancy in elevation of door skin lateral surface, so air flows is more level and smooth, and the outward appearance of car body is better.Therefore, automobile door glass 5 preferred arrangements are in the outside of vehicle.At this moment, car is inboard to be extended the front end of lip 65 and contacts with interface branch between car inside side walls 30 and the diapire 40, and automobile door glass 5 flexibly is fixed up.

When automobile door glass 5 is partial to the cars inboard, thus the inboard displacement or the vibration of extending lip 65 meeting bendings or being compressed absorption automobile door glass 5 of car.

Car outside sealing lip 50 extends towards the inside of the U-shaped section of glass run body 11 from the front end of car outside sidewall 20.The same with car inner seal lip 60, the inboard bonded assembly part with car outside sidewall 20 in the sealing lip 50 of the car outside also is provided with a part than book.This part than book has been arranged, and car outside sealing lip 50 becomes and is easy to bending.Be provided with low sliding part continuously on the surface of car outside sealing lip 50 and car outboard cover lip 21, thereby form the low friction member 51 of car outside sealing lip.The low friction member 51 of car outside sealing lip is harder than the material that constitutes glass run body 11.

When automobile door glass 5 was inserted into glass run body 11 inboard, the front end of car outside sealing lip 50 contact with the lateral side wire of automobile door glass 5, and formation seals between automobile door glass 5 and glass run 10E.Therefore, automobile door glass 5 can move up and down smoothly.In addition, as mentioned above because the surface of car outside sealing lip 50 has low friction member, so automobile door glass 5 can more easily move up and down.

Similarly, the inboard of car outside sidewall 20, also have low friction member, form the low friction member 51 of car outside sealing lip thus at the inboard position of extending lip 65 front end moving contacts of car.Therefore, car outside sealing lip 50 can slide smoothly.Because car outside sealing lip 50 is less than car inner seal lip 60, therefore, automobile door glass 5 is easy to just to be positioned the interior outside of glass run body 11.

The inboard of diapire 40 has the low friction face 42 that is made of low friction member.Automobile door glass 5 moves up and down smoothly, and its front end contacts with the low friction member 42 of bottom under the condition that does not produce abnormal noise simultaneously.The low friction member 42 of bottom has a plurality of low friction grooves 43 along its length.Utilize these low friction grooves 43, the dust that sticks on the low friction member 42 in bottom just can be drained.

The side of the low friction member 42 in bottom has teat 44 along car inside side walls 30 and car outside sidewall 20 on Width.Bottom surface teat 44 is the plane with car inside side walls 30 and car outside sidewall 20 contacted parts, simultaneously when glass run 10E is installed in the conduit 3, the teat 44 of bottom surface contacts with car outside sidewall 20 with car inside side walls 30 respectively, and they are supported, prevent that them from dropping to the inside of glass run body 11, this glass run body 11 just can keep the section shape of U-shaped like this.

Have car outside

groove

41,41 on connecting bridge between car outside sidewall 20 and the diapire 40 and the connecting bridge between car inside side walls 30 and the diapire 40 respectively.Utilize these car outside

grooves

41,41, car outside sidewall 20 and car inside side walls 30 just can be with respect to diapire 40 flexible bendings, and glass run 10E also can be inserted in the conduit 3 of doorframe 2 simultaneously.

If have teat 44 on the diapire 40, so when automobile door glass 5 is inserted in the glass run body 11, the inboard front end that extends lip 65 of car can partly be that the bending part between car inside side walls 30 and the diapire 40 contacts with the boundary between bottom surface teat 44 and the car inside side walls 30, so bottom surface teat 44 just can stably be fixed the inboard front end that extends lip 65 of car.Therefore car inner seal lip 60, car inboard extension lip 65 and car inside side walls 30 just can more stably constitute the hollow part of triangle, thereby prevent that hollow part from being collapsed by crowded in automobile door glass 5 vibration processes.

As mentioned above, the low friction face 61 of car inner seal lip, the low friction face 51 of car outside sealing lip and the low friction face 42 of bottom surface constitute by low friction member.The low friction face 24 of the low friction face 34 of car inside side walls and car outside sidewall also is made of low friction member.

In the embodiment shown in Figure 11 and 12, low friction member is formed by thermoplastic elastomer, and it is harder than the thermoplastic elastomer that forms glass run body 11.The glass run body of being made by thermoplastic elastomer 11 is softer than low friction member.When this thermoplastic elastomer is olefin-based thermoplastic elastomer, for example, harder thermoplastic elastomer can adopt that rubber content is 40%, acrylic resin content is 60% EPDM, when thermoplastic elastomer is softer thermoplastic elastomer, for example, it can adopt that rubber content is 70%, acrylic resin content is 30% EPDM.

In addition, when glass run body 11 is formed by thermoplastic elastomer, particularly when glass run is made by thermoplastic elastomer, the present invention shows better effects, this be because, as mentioned above, thermoplastic elastomer has good performance aspect capacity rating and the lightweight, but on fatigue property, can be worse than the glass run body of rubber system slightly, but by forming hollow part, this weakness is overcome also.

The 6th embodiment

Below, based on Figure 13 and 14 the sixth embodiment of the present invention is described.

The glass run 10F of the 6th embodiment and the 3rd embodiment are basic identical in shape, and its difference only is the constituent material difference.Therefore the explanation of omission and the 5th embodiment same parts here, and different parts only is described.

In the 6th embodiment, glass run body 11, car outside sealing lip 50 and car inner seal lip 60 constitute by neoprene EPDM.On the low friction face 24 of the low friction face 34 of the low friction face 51 of the low friction face 61 of car inner seal lip, car outside sealing lip, car inside side walls and car outside sidewall, use low-friction material as low friction polyurethane paint.

Low friction face 42 adopts polyurethane coating or the flocculus such as nylon short fibre.Then, diapire 40 bulging form bottom surface teat 44 with at both ends side on the broad ways, thereby prevent that car outside sidewall 20 and car inside side walls 30 from dropping.The inboard front end that extends lip 65 of car contacts with bottom surface teat 44, this sample car inner seal lip 60, the inboard shape of extending lip 65 and car inside side walls 30 formation general triangular of car.

In addition, this low friction member can adopt other material outside the polyurethane coating, as long as its friction drag is low, as TPO pad, nonwoven fluorine resin, polyethylene pads or silicon coating.

To the of the present invention the 7th and the 8th embodiment be described based on Figure 15 to 18 below.The 7th embodiment

Based on Figure 15 and 16 the 7th embodiment is described below.

The basic structure of glass run 10G is identical with fwd embodiment.Car outside sealing lip 50 extends towards the inside of the U-shaped section of glass run body 11 from the front end of car outside sidewall 20.In the sealing lip 50 of the car outside, be provided with a part than book with sidewall 20 inner face bonded assembly positions, the car outside.This part than book has been arranged, and car outside sealing lip 50 becomes and is easy to bending.Be provided with low sliding part continuously on the surface of car outside sealing lip 50 and car outboard cover lip 21, thereby form the low friction face 51 of car outside sealing lip.The low friction face 51 of car outside sealing lip is harder than the material of glass run body 11.

Extension lip 55 in the car outside stretches out from the front end of car outside sealing lip 50.This car outside extension lip 55 bends towards car outside sidewall 20 from the front end of car outside sealing lip 50, and turn of bilge wherein forms the bending part 52 of car outside sealing lip.Lip 55 integrally bending cambers are extended in the car outside, form the convex surface towards car outside sidewall 20.Determine that the car outside extends the length of lip 55, make when entering the inside of glass run body 11 that even when automobile door glass 5 vibrates outermost, the medial surface that lip 55 also can touch sidewall 30 outside the car is extended in the car outside in the end of automobile door glass 5.Thus, when automobile door glass 5 was inserted in the glass run body 11, lip 55 was extended in car outside sealing lip 50, the car outside and car outside sidewall 20 just can form leg-of-mutton hollow part definitely.

As preferably, the length that lip 55 is extended in the car outside should make its front end touch boundary part between bottom surface teat 44 and car outside sidewall 20 medial surfaces.Thus, when automobile door glass 5 outside car during sidesway, the preceding end movement that lip 55 is extended in the car outside can be restricted, and forms a space between the lip 55 thereby can extend outside car outside sidewall 20 and car outside sealing lip 50 and car, and flexibly fixes automobile door glass 5 with car outside sealing lip 50.Thus, just can flexibly, stably absorb the vibration of automobile door glass 5.

Because the front end that lip 55 keeps car outside sealing lip 50 is extended in the car outside, so summit of the hollow part of triangle, the bending part 52 that is car outside sealing lip just contacts with the side formation line of automobile door glass 5, thereby forms sealing between automobile door glass 5 and glass run 10G.Thus, automobile door glass 5 just can move up and down smoothly.In addition, as mentioned above, owing to have low friction member on the surface of car outside sealing lip 50, so automobile door glass just can more easily move up and down.

The inboard of car outside sidewall 20, the position of extending lip 55 front end moving contacts with the car outside equally also have low friction member.Therefore, the front end of car outside extension lip 55 just can slide smoothly.

Because lip 55 is extended than car outside sealing lip 50 books in the car outside, and it is protruding in car outside sidewall 20, even therefore when automobile door glass 5 vibrations, thereby the car outside extend lip 55 also can be easily crooked and distortion absorb vibration.In addition, because car outside sealing lip 50, lip 55 is extended in the car outside and car outside sidewall 20 can form the hollow part of triangle definitely, thus so the hollow part elastically deformable of this triangle bed knife of fixing automobile door glass 5 and guaranteeing to be scheduled to.

Because car outside sealing lip 50 is littler than car inner seal lip 60, so automobile door glass 5 is easy to just can navigate to the car outside in glass run body 11.

The car inner seal lip 60 of present embodiment is identical with the 5th and the 6th embodiment.Therefore its explanation is omitted.

The medial surface of diapire 40 has the low friction face 42 that is made of low friction member.Automobile door glass 5 moves up and down smoothly, and its front end contacts with the low friction member 42 of diapire under the condition that does not produce abnormal noise simultaneously.The low friction member 42 of this bottom has a plurality of low friction grooves 43 along its length.These low friction grooves 43 have been arranged, and the dust that sticks on the low friction member 42 in bottom just can be drained.

The side of the low friction member 42 in bottom has teat 44 along car inside side walls 30 and car outside sidewall 20 on Width.This teat 44 of bottom surface with car inside side walls 30 and car outside sidewall 20 contacted parts be the plane, simultaneously when glass run 10G is installed in the conduit 3, the teat 44 of bottom surface contacts with car outside sidewall 20 with car inside side walls 30 respectively, and support them, thereby prevent that them from dropping to the inside of glass run body 11, this glass run body 11 just can keep the section shape of U-shaped like this.

Have car outside

groove

41,41 on connecting bridge between car outside sidewall 20 and the diapire 40 and the connecting bridge between car inside side walls 30 and the diapire 40 respectively.These car outside

grooves

41,41 have been arranged, and car outside sidewall 20 and car inside side walls 30 just can be with respect to diapire 40 flexible bendings, and glass run 10G also can be inserted in the conduit 3 of doorframe 2 simultaneously.

If have teat 44 on the diapire 40, so when automobile door glass 5 is inserted in the glass run body 11, car is inboard extend lip 65 front end can and bottom surface teat 44 and car inside side walls 30 between the boundary part, be that bending part between car inside side walls 30 and the diapire 40 contacts, so bottom surface teat 44 just can firmly be fixed the inboard front end that extends lip 65 of car.Therefore car inner seal lip 60, car inboard extension lip 65 and car inside side walls 30 just can more stably constitute the hollow part of triangle, thereby prevent that hollow part from being collapsed by crowded in automobile door glass 5 vibration processes.

As mentioned above, the low friction face 61 of car inner seal lip, the low friction face 51 of car outside sealing lip and the low friction face 42 of diapire constitute by low friction member.The low friction face 24 of the low friction face 34 of car inside side walls and car outside sidewall also is made of low friction member.

The used thermoplastic elastomer of the low friction member thermoplastic elastomer more used than glass run body 11 is hard.The glass run body of being made by thermoplastic elastomer 11 is softer than low friction member.When this thermoplastic elastomer is olefin-based thermoplastic elastomer, for example, relatively harder thermoplastic elastomer can adopt that rubber content is 40%, acrylic resin content is 60% EPDM, when thermoplastic elastomer is softer thermoplastic elastomer, for example, it can adopt that rubber content is 70%, acrylic resin content is 30% EPDM.

In addition, when glass run body 11 is formed by thermoplastic elastomer, particularly when glass run is made by thermoplastic elastomer, the effect preferably that the present invention shows, this be because, as mentioned above, thermoplastic elastomer has good performance aspect capacity rating and the lightweight, but on fatigability, can be worse than the glass run body of rubber system slightly, but by forming hollow part, this shortcoming is overcome also.The 8th embodiment

Below, based on Figure 17 and 18 eighth embodiment of the present invention is described.

The glass run 10H of the 8th embodiment and the 7th embodiment are basic identical in shape, and its difference only is the constituent material difference.Therefore the explanation of omission and the 7th embodiment same section here, and different parts only is described.

In the 8th embodiment, glass run body 11, car outside sealing lip 50 and car inner seal lip 60 constitute by neoprene EPDM.The low friction face 24 of the low friction face 51 of the low friction face 61 of car inner seal lip, car outside sealing lip, the low friction face 34 of car inside side walls and car outside sidewall all scribbles for example low friction polyurethane paint.The low friction face 42 of bottom surface adopts the coating of polyurethane coatings or such as flocculus such as nylon short fibres.Then, diapire 40 bulging form bottom surface teat 44 with at both ends on the broad ways, thereby prevent that car outside sidewall 20 and car inside side walls 30 from dropping.The inboard front end that extends lip 65 of car contacts with bottom surface teat 44, and this sample car inner seal lip 60, car inboard extension lip 65 and car inside side walls 30 just form and be close to leg-of-mutton shape.
