Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door opening / closing device, and more particularly to a vehicle door opening / closing device suitable for promoting a flush surface of a door outer handle.

[0002]

2. Description of the Related Art Recently, automobiles tend to improve their high-speed performance, and there is a strong demand for reducing wind noise during running. Therefore, there is an increasing momentum to promote so-called flash surface formation, which is to eliminate the unevenness from the outer surface of the vehicle body as much as possible.

By the way, for the convenience of releasing the door latch, a part of the periphery of the door outer handle in the door panel is depressed or the door outer handle itself is projected from the surface of the door panel. It is necessary to provide a space for your fingers to hang on.

[0004]

As a result, not only is the flash surface around the door outer handle obstructed, but also the degree of freedom in vehicle body design is impaired.

The present invention has been devised in order to eliminate such disadvantages of the prior art, and its main purpose is to design a vehicle body for promoting flash surface around the door outer handle. An object of the present invention is to provide an improved vehicle door opening / closing device for increasing the degree of freedom.

[0006]

According to the present invention, such an object is provided at the opposed portions of the open end of the opening / closing body and the opening of the vehicle body so as to hold the opening / closing body such as a door closed. In a vehicle door opening and closing device having a latch device and a striker, and a door outer handle for performing an engagement release operation between the latch device and the striker from outside the vehicle,
A drive device for moving at least one of the latch device and the striker along the opening / closing direction of the opening / closing body, and the opening direction of the opening / closing body prior to the disengagement of the latch device and the striker. With a signal generating means for giving a drive command to the drive device,
This is achieved by arranging the operating end of the door outer handle so as to be located on the open end side of the opening / closing body.

[0007]

According to this structure, when the latch device and the striker are disengaged, the drive device moves the latch device or the striker in the door opening direction to operate the door outer handle. The required gap can be created between the opening side edge of the door and the opening inner edge of the vehicle body. Therefore, when the door is closed, there is no need to provide a space around the door outer handle for inserting a fingertip, so that the area around the door outer handle can be made substantially flat.

It is designed to be converted into the rotational force of.

Next, the latch mechanism 5 provided on the door 2 side will be described.

As shown in FIGS. 6 and 7, the latch mechanism 5 is basically of a known type, and is provided inside a casing 29 in which a guide groove 28 is provided to allow the striker 8 to enter. Is a latch member 30 which is rotatable by being pressed by the striker 8 and which is urged to rotate in the returning direction by a spring means (not shown), and a pair of ratchet pawls 31a provided at appropriate positions on the outer periphery of the latch member 30.・ 31
A ratchet pole 32 that engages with b and prevents the latch member 30 from returning is pivotally supported.

A notch 33 that engages with the striker 8 is formed at a proper position on the outer periphery of the latch member 30. The ratchet pole 32 is constantly biased by a spring 34 in a direction to engage with the ratchet pawls 31a and 31b,
Rotation of the latch member 30 in the direction in which the striker 8 enters the guide groove 28 is not hindered, but in the direction in which the striker 8 is disengaged, one of the ratchet pawls 31a and 31b is engaged to engage the latch member 30. The rotation is restricted so that the engagement between the striker 8 and the latch member 30 is maintained.

The casing 29 of the latch mechanism 5 is provided with a link mechanism 35 for operating the ratchet pole 32. As shown in FIG. 7, the link mechanism 35 has a first portion pivotally supported at an intermediate portion to perform a seesaw-type tilting motion.
The second levers 36, 37 and the first lever 36 with one end on the upper side
And a link member 39 which is pivotally attached to the other end and is engaged with the second lever 37 on the lower side through an elongated hole 38 in the vertical direction.

The first lever 36 has one end 36a connected to the lever 4 of the door outer handle 1 and the other end 36b connected to a door inner handle (not shown), and is always biased by a spring in the returning direction. As is well known, even if either the outer or inner door handle is operated, the first lever 36 tilts in the same direction, and the operations of the outer and inner door handles do not interfere with each other.

One end 37a of the second lever 37 is connected to a key cylinder (not shown) and the other end 37b is connected to a silcon knob (not shown).
The seesaw motion is performed by pushing and pulling 37b.

The link member 39 follows the tilting movement of the first lever 36 and moves up and down, and at the same time, the second lever 3
Following the tilting of 7, the lower end 39a thereof is swung in the left-right direction. The position of the lower end 39a of the link member 39 is
It is selectively determined according to the direction of the second lever 37, that is, the lock / unlock state by the key cylinder or the silcon knob.

Link member 39 and ratchet pole 32
Is provided with projections 39b and 32a which are engaged with each other in a position where the link member 39 is tilted to the right, that is, when the silcon knob or the door key is unlocked.
An open switch 40 is provided for detecting tilting of the first lever 36, that is, operation of the door outer handle 1. The output of the open switch 40 is connected to the control circuit C and used as a signal for controlling the DC motor 16.

Next, the operating procedure of the above embodiment will be described.

First, in the completely closed state where the latch mechanism 5 and the striker 8 are engaged, the latch switch 41 for detecting the fully latched state of the latch member 30 is shown in FIG.
As shown in (A), the DC motor 16 is in the pushed state, and the DC motor 16 is in the stopped state.

On the other hand, in this state, the eccentric pin 22
Is located on the side opposite to the rotational position shown in FIG. 5, and therefore the striker 8 is located inside the vehicle body 6 shown by the solid line in FIG.

Next, when a door open signal is issued from the infrared oscillator toward the light receiving section S provided on the outer surface of the door 2 adjacent to the door outer handle 1, the DC motor 16 is positively received in response to the signal. A current flows in a direction that drives the striker 8 outward, that is, drives the striker 8 outward.

By the normal rotation of the DC motor 16, the eccentric pin 22 rotates in the counterclockwise direction in FIG. 5 around the cam shaft 23 of the final stage gear 24 to move the slide plate 15 to the left. Along with the leftward movement of the slide plate 15, the striker 8 is moved along the guide recess 13 to the forward position outside the vehicle compartment (imaginary line in FIG. 3).

In this way, the open end of the door 2 moves outward with the movement of the striker 8 (arrow A in FIG. 1).
As a result, a sufficient gap (G dimension in FIG. 1) for inserting a finger is provided between the free end (operating end) of the door outer handle 1 and the inner edge of the opening of the vehicle body 6.

When the door outer handle 1 is pulled outward (arrow B in FIG. 1) in this state, one end 36a of the first lever 36 linked to the door outer handle 1 tilts downward. Then, the link member 39 is displaced downward following the tilting movement of the first lever 36. At this time, if the second lever 37 is in the unlocked position, the link member 39 is in the position shown by the solid line in FIG.
9 and the projections 39b and 32a of the ratchet pole 32 are engaged with each other, and the engagement between the ratchet pole 32 and the ratchet pawl 31a on the full latch side is released. Then, the latch member 30 returns to rotate, the striker 8 is released from the notch 33, and the door becomes free.

When the door 2 is closed from the open state, FIG.
As shown in FIGS. 6A to 6C, the latch member 30 rotates while the striker 8 is engaged with the notch 33. At this time, since the striker 8 is located outside the vehicle body through the above-described process, the full-latch state shown in FIG. 6C is realized before the weather strip 10 provided on the door 2 side is pressed and deformed. . In this state, although it is in the full-latch state, it is apparently in a so-called half-door state and before the pressing reaction force of the weatherstrip 10 is large, it is brought into the full-latch state with a relatively small closing operation force. be able to.

As described above, the latch member 30 is shown in FIG.
When rotated to the full-latch position shown in (C), the latch switch 41 is pushed in and a current flows in a direction to reverse the DC motor 16, that is, to retract the striker 8.

As the eccentric pin 22 rotates in the clockwise direction in FIG. 5 with the reverse rotation of the DC motor 16, the slide plate 15 and the striker 8 are forcibly forced along the guide recess 13 toward the interior of the vehicle. It can be slid. When the eccentric pin 22 rotates by a predetermined angle (180 degrees), a position switch (not shown) incorporated in the drive device 9
The DC motor 16 stops according to the position signal of 1, and the completely closed state is realized again.

When the door inner handle is operated to open the door from the closed state, the open switch 40 detects the tilting of the first lever 36 caused by the operation of the door inner handle. Upon receiving this detection signal, the DC motor 16
Rotates normally, and the striker 8 is driven outward. At the same time, the link member 3 that follows the tilting movement of the first lever 36
By the downward displacement of 9, the ratchet pole 32 and the ratchet pawl 31a on the full-latch side are disengaged, and the door 2 is opened, as described above.

In the above embodiment, the door outer handle 1 is formed by forming an appropriate recess 42 in a portion of the vehicle body 6 adjacent to the free edge of the door outer handle 1.
The stroke of the open end of the door 2 required for the above operation is minimized.
By increasing the eccentricity of the door outer handle 1, it is possible to provide a sufficient gap for operating the door outer handle 1 without providing the recess 42. Further, the door opening command signal for driving the striker 8 outward from the outside of the vehicle is not limited to infrared rays, but may be radio waves. In this case, the receiving antenna can be embedded in glass.

FIG. 8 shows a second embodiment of the present invention. In addition,
The parts corresponding to those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In FIG. 8, the door outer handle 43 is composed of a straight arm extending substantially horizontally along the inner surface of the door outer panel 2a, and its front end is pivotally supported by a bracket 44 provided in the inner space of the door 2. The rear end (operating end) is projected from the open end side end surface 2c of the door 2. In this case, the rear end of the door outer handle 43 is completely hidden inside the open end of the door outer panel 2a.

The middle portion of the door outer handle 43 is engaged with one end 36a of the first lever 36 for releasing the latch device 5, and the operating force of the door outer handle 43 is applied to the door outer handle 43 as in the first embodiment. It is adapted to be transmitted to the first lever 36.

Also in the second embodiment, the striker 8 receives the door open signal from the infrared oscillator or the radio wave oscillator.
Is driven outward, and as shown by an imaginary line in FIG. 8, there is a gap between the open side edge of the door 2 and the outer surface of the vehicle body, and the door outer handle 43 can be accessed from this gap. When the rear end of the door outer handle 43 is pushed down in this state, the door outer handle 43 tilts around the pivotally supported end with the bracket 44. Then the first lever 36
One end 36a of the ratchet tilts downward, and the ratchet pole 32
And the ratchet pawl 31a on the full-latch side are disengaged, and the door becomes free.

FIG. 9 shows a modification of the second embodiment. In this embodiment, the door outer handle 46 is pivotally supported at its intermediate portion by the bracket 44, and its front end is engaged with the one end 36a of the first lever 36 via the link rod 47. In the case of this configuration, the door is opened by pulling the operation end of the door outer handle 46 upward. In addition, the pivot 48 of the door outer handle 46,
A torsion spring 49 that urges the operation end of the door outer handle 46 downward is wound, and a stopper 50 that defines the rotation limit of the door outer handle 46 is provided on the bracket 44 in a protruding manner. It goes without saying that the components corresponding to the torsion spring 49 and the stopper 50 are also incorporated in the component shown in FIG. ,

Although the above embodiment has been described using the electric motor, the present invention is not limited to this. For example, an actuator driven by fluid pressure may be used. It is also possible to configure the latch mechanism side so that it can move linearly.

[0041]

As described above, according to the present invention, by moving the door, which is held closed, in the opening direction by the drive device, the gap required for operating the door outer handle is set to the open side edge of the door and the vehicle body. Between the inner edge of the opening and the inner edge of the opening. Therefore, in the completely closed state, a space for inserting a fingertip is not required around the door outer handle, so that the area around the door outer handle can be substantially flattened. Therefore, it is possible to improve the degree of freedom in vehicle body design in promoting the flash surface. Also, since the door outer handle cannot be operated when the door is closed, there is no need to lock the door when leaving the vehicle for a short time, which is a secondary effect that the annoyance of the door lock can be eliminated. There is also.
