Description

Automobile-used glove box fastener

Technical field

The utility model relates to a kind of glove box fastener, specifically, relates to a kind of automobile-used glove box fastener that is applied to fascia.

Background technology

In main storing part at fascia---the glove box to be opened/closed, glove box fastener is the vitals that the realization glove box cuts out unlatching.The glove box door of general design is latched in two kinds of patterns: the one, be arranged in the upper middle position and the instrument panel snap close of glove box, and this is called as the single-point snap close, and the one, be distributed in the top and the instrument panel snap close of glove box both sides, this is called as the two point snap close.

The structure of single-point snap close is comparatively simple, and usually, parts such as the unlatching spanner of lock and latch hook, lock fit together (spanner and latch hook are at same position), are positioned at the centre position of glove box.But for the car of inner broad, driver's operation unlatching spanner is opened glove box and is just become uncomfortable.Therefore in car than large level, recently the glove box fastener position of opening spanner occur a kind of be arranged near in the middle of the vehicle, the trend in the left side of glove box.The glove box lock of this layout is opened spanner and just is in two different positions with latch hook, and traditional single-point lock button-type formula just can not meet design requirement.But the two point snap close is for the dimension precision requirement height of part, and the Noise Suppression that in use vibrations is produced and the control sound aspect when the closing difficulty that becomes, and cost is higher.

The utility model content

The technical problems to be solved in the utility model is, when glove box lock is opened spanner and is arranged to separate with the latch hook position, provides a kind of novel automobile-used glove box door lock construction to satisfy the needs of moulding and function, makes simple in structurely simultaneously as best one can, reduces cost.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of automobile-used glove box fastener, comprise the drive link of opening between spanner, latch hook assembly, unlatching spanner and the latch hook assembly, the latch hook assembly is fixed on the glove box door, lock in described drive link one end end axle journal and the latch hook assembly forms and is rotationally connected, and the other end and unlatching spanner are for fixedlying connected.

Adopting latch hook assembly, unlatching spanner and drive link in the glove box fastener of the present utility model is three individual part, and lock is an independent assembly that is pre-assembled, and the drive link both sides are the revolute pair connection, and therefore simple in structure, assembling easily.Opening spanner and drive link is a kind of detachable clamping fixation structure, and installing does not need instrument, and locking bar and lock part just can be closed like this, and is invisible after being assemblied on the glove box.

The specific embodiment

According to Fig. 1 to Figure 12, provide preferred embodiment of the present utility model, and described in detail below, enable to understand better function of the present utility model, characteristics.

Be positioned at the copilot front on instrument panel 1 right side as glove box among Fig. 12,2 times ora terminalis of glove box are connected with instrument panel with two hinges, and the upper end is connected with the snap close of instrument panel by lock assembly 4, thereby realize the locking and the unlatching of glove box.After the unlatching, glove box can rotate around hinge axis, is opened to maximum position under action of gravity.

As shown in Figure 2, glove box 2 comprises outer cover plate 2a and internal conflict 2b, and the inner surface of internal conflict 2b and outer cover plate 2a is welded to each other together.When 2a and 2b lump together, form a cavity part at upside.Glove box lock assembly 4 is arranged in this cavity, and is installed on the inner surface of internal conflict 2b.

As Fig. 3, an end axle journal 5a of drive link 5 is installed in the supported hole of internal conflict, and other end axle journal 5b is installed in the supported hole of lock 13.Lock 13 usefulness screws 9 are fastened on the internal conflict 2b.Like this, drive link 5 can be around its back shaft rotation.

In Fig. 4, latch hook assembly 8 is made up of lock 13, dead bolt 7, dead bolt limiting plate 12, dead bolt return spring 11 and dead bolt limiting plate return spring 10.As Fig. 5, the axle journal 7a at dead bolt 7 two ends, 7b are installed in the corresponding hole of lock, 11b on the

torsionspring

11 and 11c are enclosed within 7a respectively, and on the 7b, 11a then acts on the 7c, 11 pairs of dead bolts 7 of spring just can produce torsional moment like this, and it can be rotarily opened after spacing being disengaged of bottom 7d.7d one side is a flat shape, is convenient to fit with limiting plate, and a side is cylindrical, when being convenient to rotate, promoting limiting plate 2 and rotates.Limiting plate 12 is closed back (as Fig. 4 state) at dead bolt, thus the locking that the effect of opposing latch bolt spring 11 keeps dead bolt.Dead bolt limiting plate return spring 10 tension limiting plates 12 make it closely contact with the moving arm 5c of drive link.

As shown in Figure 6, the resilient clip 3a of

glove box spanner

3,3b is connected on the drive link 5, and the two connects in aggregates closely like this.The required part of assembling that does not have other, so cost is low, and simple installation.

The motion process of the open and close of following mask body narration glove box fastener:

As shown in Figure 7, when spanner 3 was pulled upwardly according to the direction shown in the arrow A, spanner 3 drove drive links 5 by same direction of rotation rotation, and just rotatablely moving of spanner is delivered to moving arm 5c on the other end from drive link one end.Moving arm rotates, thereby promotion dead bolt limiting plate 12 overcomes the pulling force of spring 10 and rotates by direction shown in the arrow B around its rotating shaft, moves to the ledge 7d that no longer blocks dead bolt until limiting plate, as shown in Figure 8.At this moment dead bolt 7 is under the active force of its return spring 11, rotatablely move till the position that jut 7c blocked by lock 13 by arrow C, snap close on the instrument panel 14 can take off from the chute of dead bolt 7 like this, the top of glove box 2 is with regard to release, can be around its underpart rotating shaft rotating opening, as Fig. 9.

As Figure 10, when closing glove box, glove box rotates up with lock assembly, contacts with dead bolt 7 until snap close 14, continues to promote glove box, and then snap close 14 promotion dead bolts 7 begin to rotate around the direction of its rotating shaft by arrow D.

As Figure 11, the jag 7d of dead bolt 7 promotes dead bolt limiting plate 12 by the rotation of direction shown in the arrow E, until slipping over limiting plate, fluting in, and promote dead bolt 7, overcome the twisting force of spring 11 and rotate, the moving dead bolt limiting plate 12 of the protruded arm 7d thruster of dead bolt rotates, slip over limiting plate 12 until dead bolt 7, limiting plate moves upward to again by till the moving arm 5c of the drive link prevention under the effect of spring 10.At this moment, dead bolt 7 limited plates 12 are locked in closed condition (as shown in Figure 4), and snap close 14 also is locked in the fluting of dead bolt 7, as shown in figure 12.

Here, latch hook assembly 8 is pre-assembled, and the spring 6 on the drive link 5 also is to be assemblied in advance on the bar, and with these two part combine and assemble on glove box is conflicted internally the time, part has only two, installs also very simple.Locking bar and lock part just can be closed like this, and is invisible after being assemblied on the glove box.

In the present embodiment, the glove box lock spanner separates with door assembly, obviously, no matter is to separate, or spanner and drive link one, and its motion process all is the same.

The front provides the description to preferred embodiment, so that any technician in this area can use or utilize the utility model.To this preferred embodiment, those skilled in the art can make various modifications or conversion on the basis that does not break away from the utility model principle.Should be appreciated that in the manual for embodiment only be a kind of preferred embodiment, modification or conversion that this embodiment is made do not break away from protection domain of the present utility model.
