[Structure] A guide 7 that is open to the front is arranged in front of a lock 6 of a back door 4, and even if the vehicle tilts and the rear opening deforms, the relative position of the back door 4 and the opening shifts. The guide 7 contacts the striker 5 on the vehicle body side to correct the position of the back door 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a back door lock structure having an upper edge pivotally attached to the back surface of a vehicle body of a vehicle such as a one-box type vehicle.

[0002]

[Prior art]

 A back door (4) is pivotally attached to the upper edge of the back opening (3) of the vehicle body (2) of a one-box type automobile (1) as shown in FIG. The lock (6) that engages with the striker (5) on the vehicle body (2) side is attached to the lower edge of the bracket.

[0003]

[Problems to be solved by the device]

 Conventionally, when a vehicle (1) having such a back door (4) leans on a curb, etc. and leans, the opening (3) of the vehicle body (2) is deformed and the back door (4) is opened and closed in this state. When it does, it becomes impossible to close the back door (4), the lock (6) of the back door (4) is destroyed, and the weather strip attached to the inner peripheral edge of the back door (4) is torn. There is a problem with that.

[0004]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention is attached to the lower edge of a back door (4) whose upper edge is pivotally attached to the rear opening (3) of the vehicle body (2), and ) Side striker (5) engaging front striker groove (6B) opening of the striker groove (6B), providing a backdoor locking structure with a guide (7) opening forward. Is.

[0005]

[Action]

 When the vehicle (1) rides on a curb or the like and opens and closes the back door (4) while leaning, the striker groove (6 B) of the lock (6) attached to the lower edge of the back door (4) The guide (7), which is arranged in front of the opening of the vehicle and is open toward the front, contacts the striker (5) on the side of the vehicle body (2), which causes the back door (4) to open the opening ( The positional shift with respect to (3) is corrected, and the striker (5) is fitted into the striker groove (6B) of the lock (6) by the guide (7).

[0006]

【Example】

 The present invention will be described with reference to an embodiment shown in FIGS. 1 to 3. A back door (3) is provided at a rear opening (3) of a vehicle body (2) of a one-box type automobile (1) as shown in FIG. 4) is attached by pivoting the upper edge, and a lock (6) as shown in FIG. 1 is attached to the lower edge of the back door (4).

The lock (6) is a housing (6A) provided with a striker groove (6B) into which the striker (5) on the vehicle body (2) side is fitted, and a lock side housed in the housing (6A). It consists of a hook (6C) that is elastically biased to. A guide (7) is disposed in front of the opening of the striker groove (6B) of the housing (6A) of the lock (6) via a bracket (7C). The guide (7) is composed of a pair of left and right guide pieces (7A, 7B), and the guide piece (7A, 7B) has an inner slope (7D, 7E) that opens forward. (7C) is fixed to the lower edge of the back door (4) by bolts (8, 8).

In the above structure, when the vehicle (1) rides on a curb or the like and is inclined, the opening (3) of the vehicle body (2) is deformed. When the back door (4) is opened in this state, the back door (4) is displaced with respect to the opening (3). Therefore, when trying to close the back door (4) again, the relative position between the lock (6) and the striker (5) on the vehicle body (2) side is displaced as shown in FIG. However, as shown in FIG. 3, the striker (5) contacts the inner slope (7E) of the guide piece (7B) of the guide (7), and the back door (4) is pushed in the direction of the arrow in FIG. Modified so that the striker (5) fits into the striker groove (6B) of the lock (6) and engages the hook (6C).

[0009]

Therefore, in the present invention, the back door can be opened and closed without being damaged even when the vehicle body is tilted.
