Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile back door provided on the rear surface of a one-box car or the like.

[0002]

2. Description of the Related Art In a back door such as a one-box car, as shown in FIGS. 5 and 6, a back door body 1 is attached to a rear surface of a body 2 via a hinge 3 and a balancer 4. As shown in FIGS. 7 and 8, the back door body 1 includes an outer panel 5 and an inner panel 6, and the outer panel 5 on the lower side of the back door window 7 is formed.
In addition, a handle 8 for opening the back door is provided.

This back door opening mechanism is constructed as shown in FIG. The back door opening handle 8 has a bracket 9 fixed to the outer panel 5 with screws 10, and a handle body 11 is rotatably supported by the bracket 9. The handle body 11 has a front end side 11a disposed between the outer panel 5 and the inner panel 6 of the back door body 1, and one end thereof is connected to a back door latch mechanism 13 mounted on the lower end portion of the back door body 1 via a screw 12. The other end of the rod 14 is connected.

The back door latch mechanism 13 fixes the back door body 1 by engaging a striker 16 attached to the body 2 facing the lower end of the back door body 1 via a screw 15. The back door latch mechanism 13 is
It is connected to the back door latch cylinder 17 via a rod 18, and the lock is released by operating a key 19. Reference numeral 20 denotes a back door latch actuator for opening the back door at the driver's seat.

Conventionally, when the back door is opened, the key 19 unlocks the back door latch mechanism 13, or the back door latch actuator 20 is operated in the driver's seat to unlock the back door latch mechanism 13.
The handle body 11 is lifted to open the back door body 1. The handle main body 11 is lifted with the handle main body 11 pulled so that the back door latch mechanism 13
The back door main body 1 can be opened by completely releasing the engagement.

[0006]

By the way, when the outer panel 5 of the back door body 1 is crushed by the impact from the rear of the back door, the distance between the outer panel 5 and the inner panel 6 becomes narrower, and the tip portion 11a of the handle body 11 is reduced. May hit the inner surface of the inner panel 6 and rotate. In this way, when the handle main body 11 rotates, the rod 14 operates and the back door latch mechanism 13 may be separated from the striker 16. As a result, the back door may be opened by the operation of the balancer 4.

SUMMARY OF THE INVENTION The present invention solves the above problems and provides a back door for an automobile which can be used as an air vent hole while preventing the operation of the back door opening handle due to the deformation of the back door. To aim.

[0008]

In order to solve the above-mentioned problems, the present invention comprises a back door body composed of an outer panel and an inner panel, and an opening handle is attached to the outer panel. An open hole is formed in the inner panel facing each other.

[0009]

When the outer panel approaches the inner panel due to the deformation of the back door body, the back door body approaches the inner panel side as the outer panel moves. Then, the handle body moves toward the open hole provided in the inner panel. In this way, the handle body does not contact the inner panel, and therefore does not rotate. On the other hand, the opening hole can be used as a working hole when mounting the handle body or the like. The open hole can also be used as an air vent hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention in which the same parts as those in FIGS. 1 and 2, the back door body 1
Is composed of an outer panel 5 and an inner panel 6,
A back door opening handle 8 is provided on the outer panel 5. The handle body 11 of the back door opening handle 8 is provided with a rod 14 that connects to a back door latch mechanism 13 arranged at the lower end of the back door body 1. On the other hand, the back door latch mechanism 1 is provided on the body 2 side.
A striker 16 that engages 3 is provided.

Reference numeral 21 is an opening hole formed in the inner panel 6 of the back door body 1 corresponding to the handle body 11 of the back door opening handle 8. The opening hole 21 is a recess for the handle body 11 when the outer panel 5 of the back door body 1 approaches the inner panel 6 side.

The opening hole 21 can be used as a working hole when the back door opening handle 8 is assembled.

According to the above construction, when the back door body 1 is deformed and the outer panel 5 moves to the inner panel 6 side, the handle body 11 enters the open hole 21 and does not rotate. As a result, the back door body 1 remains in the locked state, so that the back door body 1 does not open.

Incidentally, FIG. 3 shows the back door body 1 from the indoor side.
The open hole 21 can also be used as an air vent hole in the room, and the air released into the back door body 1 is exhausted to the outside through the air vent hole 23 on the outside of the sealing material 22.

Further, in FIG. 4, a cover 24 is attached to the open hole 21, and the back door trim 25 can be fixed by the cover 24.

[0016]

As described above, according to the automobile back door of the present invention, since the opening hole is formed in the inner panel facing the opening handle attached to the outer panel, the back door body is deformed. It is possible to prevent malfunction of the opening handle. Further, since the open hole can be used as a work hole when the opening handle is attached, the work efficiency can be improved. Further, the open hole can be used as an air vent hole.
