[0017] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0018] A front wall lock fixing part, comprising: a fixed plate part 1. The fixed plate part 1 is provided with a bolt through hole 11. The bolt through hole 11 matches the assembly point on the vehicle body. The fixed plate part 1 is further provided with a pre-positioning structure 12. The pre-positioning structure 12 surrounds the four corners of the lock body assembly. Specifically, the number of the pre-positioning structure 12 is four. The pre-positioning structure 12 corresponds to the four vertex ends of the lock body assembly respectively.

[0019] The pre-positioning structure 12 comprises a positioning plate 121, a spring 122, a sliding block 123, a driving rod 124 and a driven rod 125. The positioning plate 121 is L-shaped to fit the top corner end of the lock body assembly. The sliding block 123 is fixedly connected with the positioning plate 121. The sliding block 123 is connected with the spring 122. The sliding block 123 extends into the fixed plate 1. The fixed plate 1 is provided with a sliding groove corresponding to the sliding block 123. The sliding groove matches the diagonal line of the lock body assembly, so that the sliding direction of the positioning plate 121 corresponds to the diagonal line of the lock body assembly. Meanwhile, the fixed plate 1 is also provided with a cavity corresponding to the spring 122.

[0020] One end of the driven rod 125 is connected with the positioning plate 121 through the sliding block 123. The other end of the driven rod 125 is provided with a driven inclined surface 1251. The driving rod 124 extends into the fixed plate 1. The driving rod 124 can slide relative to the fixed plate 1 in the vertical direction. The driving rod 124 is provided with a driving inclined surface 1241. The driving inclined surface 1241 fits the driven inclined surface 1251. The driving rod 124 is also provided with a limiting plate 1242. The limiting plate 1242 is fixedly connected with the driving rod 124. The limiting plate 1242 surrounds the driving rod 124. The limiting plate 1242 protrudes from the surface of the driving rod 124. Thus, the limiting plate 1242 can abut against the inside of the fixed plate 1. Meanwhile, the limiting plate 1242 is provided with a notch corresponding to the driven rod 125. In summary, the driving rod 124 is limited by the driven inclined surface 1251 and the limiting plate 1242. In the default state, the driving rod 124 protrudes from the surface of the fixed plate 1. The height of the part of the driving rod 124 protruding from the fixed plate 1 is higher than the height of the positioning plate 121. On the other hand, the driving rod 124 is also provided with a receiving groove 1243. The receiving groove 1243 corresponds to the driven inclined surface 1251.

[0021] In actual application, after the staff completes the assembly of the fixed plate 1, the lock body assembly is held and aligned with the to-be-installed area of the fixed plate 1. Because in the default state, the height of the driving rod 124 is higher than the height of the positioning plate 121. Therefore, the lock body assembly first contacts the end of the driving rod 124. At this time, the staff pushes the lock body assembly towards the fixed plate 1. Under the extrusion of the lock body assembly, the driving rod 124 starts to slide towards the inside of the fixed plate 1.

[0022] When the driving rod 124 starts to slide, the driving inclined surface 1241 and the driven inclined surface 1251 extrude each other, so that the driven rod 125 starts to slide under the driving of the driving rod 124. In this way, the driven rod 125 drives the positioning plate 121 to move away from the lock body assembly through the sliding block 123. In this process, the four positioning plates 121 are in an open state. The sliding block 123 compresses the spring 122, so that the spring 122 gradually accumulates elastic force.

[0023] With the movement of the driving lever 124, the driving slope 1241 will be separated from the driven slope 1251. At this time, the driven slope 1251 is in contact with the side wall of the driving lever 124, so that the driven lever 125 can maintain the current state, and the positioning plate 121 maintains the open state. With the continuous movement of the driving lever 124, the driven slope 1251 will pass through the limiting plate 1242 through the gap on the limiting plate 1242. Finally, the lock body assembly is fully in contact with the fixed plate member 1, and the driving lever 124 is completely pressed into the fixed plate member 1. At this time, the accommodating groove 1243 moves to a position corresponding to the driven slope 1251. Thus, the driven slope 1251 loses the restriction of the driving lever 124, and under the action of the elastic force of the spring 122, the driven slope 1251 has a movement tendency of extending into the accommodating groove 1243. That is, the positioning plate 121 has a tendency to approach the lock body assembly.

[0024] When the lock body assembly is fully in contact with the fixed plate member 1, the positioning plate 121 approaches the lock body assembly under the action of the elastic force of the spring 122, thereby pushing the lock body assembly. At this time, the lock body assembly is loosened, and then the lock body assembly will move to the predetermined installation position under the pushing of the positioning plate 121. At the same time, the positioning plate 121 will pre-position the lock body assembly. Thus, the worker can start the assembly of the lock body assembly.

[0025] In summary, during the process of approaching the lock body assembly to the fixed plate member 1, the positioning plate 121 is first opened and then closed with the movement of the lock body assembly. In this way, the positioning plate 121 first provides sufficient movement space for the lock body assembly, and then calibrates the position of the lock body assembly, so that the worker only needs to place the lock body assembly in an approximate assembly area during the assembly of the lock body assembly, thereby greatly facilitating the operation of the worker.

[0026] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
