[0070] As shown in Figure 2 and Figure 3 , the vehicle body can further include a bumper beam mounting member 4, which can be connected to the first connecting plate 30. The bumper beam mounting member 4 can be a bolt, but is not limited thereto. The bumper beam mounting member 4 can be pre-installed on the first connecting plate 30 before the vehicle body is spliced, so as to facilitate the installation of the bumper beam 5 in the subsequent process. At the same time, the bumper beam mounting member 4 can also be used to provide a positioning reference for the splicing and assembly of the side wall module 2, the rear wall module 1 and the rear longitudinal beam 3, thereby improving the accuracy of the vehicle body assembly.

[0071] The bumper beam mounting member 4 can be multiple, for example: 2, 3, 4, 5, etc., which can improve the installation stability of the bumper beam 5. The multiple bumper beam mounting members 4 can be arranged at intervals, and at least one of the multiple bumper beam mounting members 4 can not be pre-installed on the first connecting plate 30, so as to facilitate the fixation of the bumper beam 5 by using the bumper beam mounting member 4 in the subsequent process. The multiple bumper beam mounting members 4 can include at least a first mounting member 41 and a second mounting member 42, and the first mounting member 41 and the second mounting member 42 are pre-installed on the first connecting plate 30.

[0072] As shown in Figures 2 to 7As shown, the second connecting part 21 can be provided with an avoiding groove 21a, and an opening of the avoiding groove 21a can be located at an edge of the second connecting part 21 close to the bumper beam mounting member 4.

[0086] In some embodiments of this disclosure, the first body portion 10 may include a rear panel body 101, and the first connecting portion 11 may be located on at least one side of the rear panel body 101 in the width direction X of the vehicle body and connected to the rear panel body 101.

[0087] like Figure 7 As shown, the first body part 10 may further include a latch assembly 102, a sill plate assembly 103, and a support frame assembly 104. The latch assembly 102 may be disposed on the rear panel body 101, and may be a trunk latch, but is not limited thereto. The sill plate assembly 103 may be connected to the rear panel body 101, and at least a portion of the sill plate assembly 103 may be disposed on the side of the rear panel body 101 near the receiving space. A portion of the sill plate assembly 103 may also be disposed on the top surface of the rear panel body 101, etc. The sill plate assembly 103 may be a trunk sill plate assembly 103, but is not limited thereto. The support frame assembly 104 may be connected to the side of the rear panel body 101 opposite to the receiving space, and can be used to provide support for the rear panel body 101, improving the structural strength and impact absorption capacity of the rear panel body 101.

[0088] In this embodiment, the rear wall module 1 can be assembled separately in the production line, that is, the lock catch assembly 102, the rocker panel assembly 103 and the support frame assembly 104 are first installed on the rear wall main body 101 to form the rear wall module 1, and then the rear wall module 1 is spliced and assembled with the side wall module 2 and the rear longitudinal beam 3. In this way, the space occupied by the tooling fixture can be reduced, and the space utilization rate of the production plant can be improved. Moreover, more operating space can be provided for the operator, and the operating efficiency and accuracy of the operator can be improved. At the same time, the assembly process of the rear wall module 1 can be synchronized with the assembly process of other modules and structural parts of the vehicle body, thereby realizing parallel production and improving production efficiency.

[0089] As shown in Figure 1 The vehicle body can further include a bumper beam 5. The bumper beam 5 can be installed on the first connecting surface through the bumper beam mounting member 4, and part of the bumper beam 5 can be located on the side of the support frame assembly 104 away from the rear wall main body 101. The impact on the rear part of the vehicle body can be absorbed by the bumper beam 5, and the probability of damage to other components of the vehicle body can be reduced.
