Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinge device for an automobile sliding door, which is provided on one side of a door opening in a vehicle body and slidably supports the door.

Such a hinge device connects the door with a smooth continuous surface to the outer surface of the vehicle body when the door is closed, and when the door is opened, it moves approximately parallel to the outside of the plane by more than the thickness of the door, and then moves along the outer surface of the vehicle body. It must be supported so that it can slide.

The hinge device for this purpose includes a board fixed to the vehicle body, a pair of swing links connected to the board and swinging while maintaining a mutually substantially parallel state, and a connecting member connecting the pair of swing links. A quadrilateral link is formed by the connecting member, and the door is slidably supported by a sliding member provided integrally with the connecting member or separately, and the swinging of the swinging link moves the door approximately parallel to the surface of the door. It is known that the device can be moved to (Refer to Japanese Unexamined Patent Publication No. 53-2818.) In the above hinge device, the movement of the door in the surface direction and the sliding movement along the outer surface of the vehicle body must be performed in conjunction. If the door slides before it moves out of plane, not only will the door not be able to be opened, but the door and the vehicle body may come into contact and be damaged. This is because if the door moves inward, there is a risk of a collision between the door and the outer panel of the vehicle body.

The present invention enables the above-mentioned linked operation to be performed reliably with a simple structure. When opening the door, the sliding movement of the door is restrained and the swinging link is swung to swing the door outward. After the parallel movement, the swinging of the swinging link is restrained and the sliding movement of the door is released.
When the door closes, the swing link is restrained from swinging until the door slides to the position of the vehicle door opening.
The present invention provides a hinge device equipped with a restraining mechanism that restrains sliding movement and releases swinging after movement is completed.

The present invention will be explained below based on embodiments shown in the drawings.

As shown in FIG. 1, a hinge 1 is provided on one side of a vehicle door opening A to support a door B, and the door B slides open and close like a sliding door to the position shown by the two-dot chain line. When opening the door B, the hinge 1 moves the door B out of the plane and then slides it, as shown in FIG.

Furthermore, as shown in FIGS. 3 to 6, the hinge 1 is connected to a base plate 2 fixed to the vehicle body and a front end of the base plate 2, and in particular, in this embodiment, a hinge 1 is connected to the front end of the base plate 2 via a guide mechanism 3. A pair of swing links including a first swing link 4 and a second swing link 5 pivoted to the base plate 2 so as to swing substantially parallel to the first swing link; The connecting member 6 to be connected forms a quadrilateral link, and the sliding member 7, which is passed across both fulcrums of the connecting member 6, is fitted into the rail 8 of the door B, and the door B is slidably supported by the rollers 71.
The interlocking operation is controlled by a restraining mechanism consisting of a control member 9 pivotally attached to the connecting member 6, a striker 10 fixed to the door B, and a cam 51 provided on the second swing link 5. ing.

To explain in detail the structure of the members related to the restraint mechanism, as shown in FIGS. 7 and 8a and 8b, the control member 9 is pivotally attached to the connecting member 6 and protrudes on the movement trajectory of the striker 10. a latch portion 91 that engages the striker 10, a restraining portion 92 into which the striker 10 can be fitted, and a pawl portion 93 that engages with the cam 51 and becomes its follower.
1 by a spring 94.
The cam 51 is connected to the restraining end 95 of the restraining portion 92 of the control member 9 when the second swing link 5 is swinging.
In this embodiment, the first cam surface 52, which is a circular arc, protrudes onto the movement trajectory of the striker 10 to restrain the striker 10 on the movement trajectory of the striker 10, and after the swinging is completed when the door is opened, the restraint end 95 is caused to stick to the movement trajectory of the striker 10. In this embodiment for dropping downward, the second cam surface 53 is a notch recessed portion into which the pole portion 93 is recessed.

Further, the guide mechanism 3, which is a component unique to this embodiment, will be described in detail with reference to FIGS. By this, the rocking connection means is used.
By engaging the shaft 31 and the first swing link 4 through the elongated hole 32, a first swing link expansion/contraction means is formed, and a pin 33 protruding from the first swing link 4 is used as a follower.
The guide mechanism 3 is configured as a movement guide means by a cam mechanism whose origin is an arcuate hole 34 drilled in the board 2, and the first swing link 4 is swingably connected to the board 2 and swings. It can be expanded and contracted,
The movement locus of the front end of the door just before it is fully closed is gradually guided along the sliding direction of the door. The first swinging link expansion/contraction means may be configured by dividing the first swinging link into two and making it slidable. The member provided with 34 may be reversed, or a plate cam may be used.

As shown in FIG. 7, when the door is closed, the guide mechanism 3 swings sequentially from the solid line position to the positions shown by the one-dot chain line and the two-dot chain line to fully close the door. In the process, as the first swing link 4 swings and falls down, the pin 33 is restrained and guided in the arcuate hole 34, and as a result, the elongated hole 32 slides on the shaft 31, causing the first swing link 4 to fall down. Expand and contract. When the motion guide means is constituted by the arcuate hole 34, the first swing link 4 is temporarily contracted at the position indicated by the dashed-dotted line, and then extended to its original length while swinging to the position indicated by the dashed-double-dotted line, which is the fully closed position. Compared to the case where the first swing link 4 is simply pivotally attached to the base plate 2, the positions of the start and end points of the swing do not change, but the locus is improved. Therefore, the door can be held securely, and the sealing performance and operability of the door can be improved.

The operation of the device according to the present invention with the above configuration is explained in the seventh section.
To explain with reference to the drawings and FIGS. 8a and 8b, when the door is opened, it swings sequentially from the position indicated by the chain double-dashed line to the position indicated by the solid line in FIG. Since the pawl portion 93 engages with and slides on the arcuate first cam surface 52 until the swinging is completed, the restraining end 95 protrudes and the striker 10 is restrained by the restraining portion 92. When the swinging is completed, the pawl portion 93 retracts into the second cam surface 53, which is a recessed notch, so that the restraining end 95 falls below the movement trajectory of the striker 10, releasing the striker 10 and locking it from swinging. do.

When closing the door, the striker 10 advancing from the right in the figure collides with the latch portion 91.
Rotate the control member 9 clockwise to move the pole part 93 out of the second cam surface 53 and into the first cam surface 52.
When the striker 16 is moved upward to release the rocking lock, the restraining end 95 protrudes and the striker 16 is restrained.

According to the present invention, the cam action between the control member provided on the connection member and the cam provided on the swing link is achieved by utilizing the mutual movement between one of the swing links constituting the quadrilateral link of the hinge and the connection member. The door is restrained from sliding while the swing link is swinging, and the swing link is restrained from swinging while the door is sliding, and the linked movement is The door operates extremely smoothly when opening and closing, completely eliminating the problem of the door moving inconveniently and causing damage to the vehicle body.

The member provided with the cam may be either one of a pair of swing links, and other cam structures may be used, such as the pole portion being hook-shaped and the second cam surface of the cam being a latching groove.
