[0031] Before describing the embodiments of the utility model in detail, the application environment of the utility model is described first. The technology of the utility model is mainly applied to the back door of the vehicle. The utility model solves the technical problem that the back door lock is inconvenient to install in the prior art, resulting in low installation efficiency of the back door lock. Since the back door lock is installed on the back door lock mounting plate, improving the back door lock mounting plate is more conducive to reducing the modification cost.

[0032] like Figures 1 to 6As shown, some embodiments of the present application provide a back door structure, including a back door inner panel 1 and a back door lock mounting plate 2 mounted on the back door inner panel 1. The back door inner panel 1 is provided with a clearance hole 11. The back door lock mounting plate 2 is provided with a receiving cavity 21, and the opening 211 of the receiving cavity 21 is arranged corresponding to the clearance hole 11, that is, the opening 211 of the receiving cavity 21 is connected with the clearance hole 11, so that the back door lock 3 can be installed in the receiving cavity 21 through the clearance hole 11 and the opening 211 of the receiving cavity 21. Such a setting facilitates the installation of the back door lock 3 on the back door lock mounting plate 2, which is conducive to improving the installation efficiency of the back door lock 3.

[0033] In the prior art, the arrangement of the back door lock 3 needs to be considered during the processing of the back door inner panel 1, and corresponding through holes and avoidance holes are set according to the arrangement of the back door lock 3, resulting in a high requirement for the stamping angle of the back door inner panel 1 during the processing. The above-mentioned arrangement of the present application enables the back door inner panel 1 to only need to be provided with the avoidance hole 11 for the installation of the back door lock 3, which is conducive to reducing the processing difficulty of the back door inner panel 1 and the processing cost.

[0034] Specifically, a local outer wall of the back door lock mounting plate 2 on one side facing away from the back door inner plate 1 is raised in a direction away from the back door inner plate 1, thereby forming an accommodating cavity 21. The opening 211 of the accommodating cavity 21 faces the clearance hole 11 of the back door inner plate 1, so that the back door lock 3 can pass through the clearance hole 11 and be installed in the accommodating cavity 21.

[0035] In some embodiments, a mounting hole 212 is provided on the side wall of the accommodating cavity 21 , and the tailgate lock 3 is detachably mounted in the accommodating cavity 21 through the mounting hole 212 , so that the tailgate lock 3 can be subsequently disassembled and assembled.

[0036] Exemplarily, four side walls may be provided in the circumference of the accommodating cavity 21, and the tailgate lock 3 is installed on one of the side walls.

[0037] In some embodiments, a flange structure 22 is provided around the opening 211 of the accommodating cavity 21 of the tailgate lock mounting plate 2, and the flange structure 22 is used to connect with the tailgate inner panel 1 around the clearance hole 11, so as to connect the tailgate lock mounting plate 2 with the tailgate inner panel 1, and the opening 211 of the accommodating cavity 21 is connected with the clearance hole 11 of the tailgate inner panel 1.

[0038] It should be noted that the flange structure 22 is arranged along the direction of the rear door inner panel 1 so that the flange structure 22 and the rear door inner panel 1 can be closely connected.

[0039] In some embodiments, in order to improve the strength of the flange structure 22 and further improve the overall structural strength of the tailgate lock mounting plate 2 , a plurality of reinforcing grooves 221 are provided on the flange structure 22 .

[0040] Furthermore, the arrangement of the reinforcement groove 221 is also conducive to solving the problem of inconvenience in painting between the back door inner plate 1 and the back door lock mounting plate 2. When painting, the paint can enter between the back door inner plate 1 and the back door lock mounting plate 2 through the reinforcement groove 221, which is also conducive to improving the service life of the back door.

[0041] It should be noted that the rear tailgate inner panel 1 and the rear door lock mounting plate 2 are connected by welding so that the rear tailgate inner panel 1 and the rear door lock mounting plate 2 are connected as one, which is beneficial to improve the stability of the connection between the rear tailgate inner panel 1 and the rear door lock mounting plate 2.

[0042] In some embodiments, the tailgate lock mounting plate 2 is integrally formed by stamping, which is beneficial to improving the stability of the tailgate lock mounting plate 2 structure.

[0043] In some embodiments, the tailgate outer panel 4 is connected to the tailgate inner panel 1 and the tailgate lock mounting plate 2 at the same time, and the tailgate lock mounting plate 2 is located between the tailgate inner panel 1 and the tailgate outer panel 4. The tailgate lock mounting plate 2 supports the tailgate inner panel 1 and the tailgate outer panel 4, so that the structure used to support the tailgate outer panel 4 can be eliminated, which is beneficial to reduce the weight of the entire vehicle and also helps to reduce costs.

[0044] Specifically, the side of the back door lock mounting plate 2 close to the opening 211 of the accommodating cavity 21 is connected to the back door inner plate 1, that is, the flange structure 22 is connected to the back door inner plate 1. The side of the back door lock mounting plate 2 away from the opening 211 of the accommodating cavity 21 is connected to the back door outer plate 4, that is, the bottom of the accommodating cavity 21 is connected to the back door outer plate 4. And the connection surface between the accommodating cavity 21 and the back door outer plate 4 is set to a plane to increase the contact surface of the connection between the two, which is conducive to improving the stability of the connection between the two, and also increases the support surface of the back door lock mounting plate 2.

[0045] It should be noted that the accommodating cavity 21 can be configured to have a structure in which the size of the cavity gradually decreases in the direction away from the back door inner panel 1, so as to reduce the space occupied by the back door lock mounting plate 2, which is beneficial to the structural design of the back door inner panel 1 and the back door outer panel 4, and is also beneficial to the installation of the back door lock 3. Such a structural design is also beneficial for the back door lock mounting plate 2 to support the back door inner panel 1 and the back door outer panel 4.

[0046] For example, in order to improve the strength of the tailgate lock mounting plate 2 and thus enhance the overall stability of the tailgate, a plurality of reinforcing ribs may be provided on the tailgate lock mounting plate 2 .

[0047] Exemplarily, the rear door outer panel 4 and the rear door lock mounting plate 2 are connected by welding so that the rear door outer panel 4 and the rear door lock mounting plate 2 are connected as one, which is beneficial to improve the stability of the connection between the rear door outer panel 4 and the rear door lock mounting plate 2.

[0048] It should be noted that the welding traces between the rear door outer panel 4 and the rear door lock mounting plate 2 can be covered by the license plate installed on the rear door outer panel 4, which will not affect the appearance of the rear door outer panel 4 and ensure the overall aesthetics of the vehicle.

[0049] To sum up, the utility model provides a tailgate structure, by setting a accommodating cavity on the tailgate lock mounting plate, and the opening of the accommodating cavity is set corresponding to the clearance hole on the tailgate inner plate, so that the tailgate lock can be installed in the accommodating cavity through the clearance hole. Such a setting facilitates the installation of the tailgate lock and is beneficial to improving the installation efficiency of the tailgate lock.
