[0029] The following detailed description discusses the implementation and use of specific examples. It should be understood, however, that the specific examples discussed are merely illustrative in nature and are not intended to limit the scope of the application.

[0030] In the present specification, when describing the positional relationship of the structures of various components, directional expressions such as "upper", "lower", "left", "right", "front", "back" and the like are not absolute, but are relative. When the various components are arranged as shown in the drawings, these directional expressions are appropriate, but when the positions of the various components in the drawings are changed, these directional expressions should also be changed accordingly.

[0031] In the present specification, "front" and "back" are defined with reference to the front-to-back direction of the vehicle X. In addition, the X direction represents the longitudinal direction of the vehicle (i.e., the direction of travel of the vehicle), the Y direction represents the lateral direction of the vehicle (i.e., the direction at a 90-degree angle with respect to the direction of travel), and the Z direction represents the vertical direction of the vehicle (i.e., the up-down direction).

[0032] A preferred embodiment of the vehicle body assembly 100 according to the present application will be described in detail below with the aid of the accompanying drawings.

[0033] As shown in Figures 1 to 4 , the vehicle body assembly 100 according to the present application comprises a bumper beam 2, a cross beam 3 (i.e., a front cross beam of the vehicle body bottom structure) positioned rearward of the bumper beam 2 with respect to the X direction of the vehicle V and extending in the Y direction of the vehicle V, and a deflector 4 positioned below the cross beam 3 with respect to the Z direction of the vehicle V. The front portion of the deflector 4 is lapped to the bumper beam 2 by a plurality of hooks 41, and the rear portion of the deflector 4 is assembled to the cross beam 3 by a plurality of positioning portions 5 and a plurality of fasteners 6. Each of the plurality of positioning portions 5 comprises a first positioning portion 51 provided on the deflector 4 and a second positioning portion 52 provided on the cross beam 3, the second positioning portion 52 being in snap-fit engagement with the first positioning portion 51 so that the deflector 4 and the cross beam 3 can be positioned with respect to each other in at least two different directions when assembled. The deflector 4 is further provided with at least one through hole 42 configured for at least one of the positioning portions 5 to be visible from below the deflector 4.

[0034] The vehicle body assembly 100 according to the present application provides pre-support and positioning in multiple directions for the deflector 4 through the provision of the plurality of positioning portions 5. At the same time, the provision of the through hole 42 solves the obstruction existing in the assembly line of sight of the deflector 4, so that the assembly personnel can clearly observe the assembly of the positioning portions 5 through the deflector 4, reducing the risk of mispositioning or collision of the deflector 4 during assembly.

[0035] Figures 5 to 7 Partial perspective views of the positioning portion 5 from different angles are shown, wherein Figure 7 is a perspective view of the positioning portion 5 from below to above. In combination with Figures 5 to 7 and Figures 8 to 10As shown in the sectional view, the first positioning portion 51 includes a clamping tongue 53 protruding from the deflector plate 4 toward the crossbeam 3, and the second positioning portion 52 includes a clamping opening 54 through which the clamping tongue 53 passes and which matches the clamping tongue 53. In addition, the second positioning portion 52 further includes a clamping groove 58 formed on the crossbeam 3, which is configured to accommodate at least a portion of the clamping tongue 53 after the clamping tongue 53 passes through the clamping opening 54.

[0036] According to an implementation variant, the clamping tongue 53 can also be provided on the crossbeam 3 and protrude toward the deflector plate 4, and the clamping opening 54 that matches the clamping tongue 53 is correspondingly provided on the deflector plate 4.

[0037] More specifically, as shown in the sectional view, Figures 5 to 7 the clamping tongue 53 includes a first segment 55 extending upward from the deflector plate 4 in a generally arched shape, and a second segment 56 extending downward from a portion of the free end face of the first segment 55 toward the deflector plate 4, wherein the dimension of the first segment 55 along the Y direction is slightly greater than the dimension of the second segment 56 along the Y direction. This curved structure of the clamping tongue 53 not only facilitates its insertion into the clamping opening 54, but also helps it to have a larger elastic space.

[0038] In the embodiment shown, the dimension of the first segment 55 along the Y direction matches the dimension of the clamping opening 54 along the Y direction, so that the deflector plate 4 and the crossbeam 3 are positioned relative to each other along the Y direction. For example, as shown in the sectional view, Figure 10 according to an embodiment, the Y-direction gap G between the first segment 55 and the clamping opening 54 is only about 1 mm, so as to facilitate the smooth insertion of the clamping tongue 53 into the clamping opening 54 and provide accurate Y-direction positioning for the deflector plate 4.

[0039] In addition, a portion of the free end face of the first segment 55 forms a first abutting face 551 that abuts downward along the Z direction against an edge portion of the clamping opening 54, so that the deflector plate 4 and the crossbeam 3 are positioned relative to each other along the Z direction and can provide pre-support for the deflector plate 4 along the Z direction.

[0040] In addition, the first segment 55 includes a second abutting face 552 oriented rearward, and the second segment 56 includes a third abutting face 553 oriented forward opposite to the second abutting face 552, which respectively abut against two opposite edge portions of the clamping opening 54 along the X direction, so that the deflector plate 4 and the crossbeam 3 are positioned relative to each other along the X direction.

[0041] In the illustrated embodiment, the guide plate 4 includes a plurality of bosses 57 protruding toward the crossbeam 3, each boss 57 having an edge from which a latch 53 extends, and at least one of these bosses 57 has a hollow structure to form the through hole 42. More specifically, the bosses 57 with hollow structures include sidewalls 571 defining the through hole 42, and the latches 53 extend upward from the upper edge of the sidewalls.

[0042] Multiple fasteners 6 and multiple positioning parts 5 are alternately arranged on the guide plate 4 along the Y direction. For example, a total of three fasteners 6 and two positioning parts 5 are arranged along the Y direction, each fastener 6 passing through a fastening boss 67 (e.g., having approximately the same protrusion height as the boss 57) protruding from the guide plate 4 toward the crossbeam 3, so as to form a fixed connection between the guide plate 4 and the crossbeam 3 at the location of the fastening boss 67. It is understood that the number and position of the fasteners 6 and positioning parts 5 are determined according to actual needs, and the present invention does not limit this. Preferably, each of the multiple fasteners 6 is a screw.

[0043] like Figure 11 As shown, when assembling the body assembly 100, after providing the air deflector 4, crossbeam 3, and anti-collision beam 2, the installer stands below the air deflector 4 and holds the front and rear of the air deflector 4 with both hands respectively. First, the front of the air deflector 4 is attached to the anti-collision beam 2 using the hooks 41. Then, the rear of the air deflector 4 is attached to the crossbeam 3 using multiple positioning parts 5 to achieve the pre-positioning of the air deflector 4 on the crossbeam 3. Finally, the air deflector 4 is fixed to the crossbeam 3 using multiple fasteners 6 to complete the assembly of the air deflector 4 on the crossbeam 3. The pre-support and positioning provided by the positioning parts 5 facilitates the subsequent assembly of the fasteners 6, and the through holes 42 allow the installer to directly observe the position of the positioning parts 5, improving the accuracy and stability of the assembly.

[0044] The technical content and features of the present invention have been disclosed above. However, it is understood that those skilled in the art can make various changes and improvements to the above-disclosed concept under the creative idea of ​​the present invention, but all of these shall fall within the protection scope of the present invention.

[0045] The above description of the embodiments is exemplary and not restrictive, and the scope of protection of the present invention is determined by the claims.
