[0025] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are only illustrative of specific ways of implementing and using the present invention, rather than limiting the scope of the present invention.

[0026] In this specification, when describing the structural positions of various components, directional expressions such as "upper", "lower", "left", "right", etc. are not absolute, but relative. When the various components are arranged as shown in the figures, these directional expressions are appropriate, but when the positions of the various components in the figures change, these directional expressions should also change accordingly.

[0027] In this specification, "front" and "rear" are both defined with reference to the front and rear directions of the vehicle in the X direction, and "inside" and "outside" are both defined with reference to the inside and outside directions of the vehicle. In addition, in this specification and the drawings, the X direction represents the longitudinal direction of the vehicle V (i.e., the driving direction of the vehicle), the Y direction represents the transverse direction of the vehicle (i.e., the left and right directions at a 90-degree angle to the driving direction), and the Z direction represents the vertical direction perpendicular to the ground (i.e., the up and down direction perpendicular to the ground).

[0028] In this specification, unless otherwise clearly defined and limited, terms such as "fixed" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a direct connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction relationship between two components. For those skilled in the art, the specific meanings of the above terms in this specification can be understood according to specific situations.

[0029] The following will describe a preferred embodiment of the present invention with the aid of Figures 1 to 7 as follows.

[0030] As shown in Figure 1 and Figure 3 the body structure A of the vehicle V of the present invention includes a (front) bumper skeleton 10 and headlight housings 20 provided at the left and right ends of the bumper skeleton 10.

[0031] The bumper skeleton 10 includes a skeleton body 11 that supports a bumper skin and mounting arms 12 connected to the skeleton body 11 through necks 16. More specifically, the necks 16 connect the skeleton body 11 and the mounting arms 12 and have dimensions smaller than those of the skeleton body 11 and the mounting arms 12, so that the mounting arms 12 that extend from both ends of the skeleton body 11 through the necks 16 can elastically deform relative to the skeleton body 11. According to one embodiment, the bumper skeleton 10 is a single piece forming the skeleton body 11, the mounting arms 12, and the necks 16. A positioning hole 13 and a first fixing portion 14 (as shown in Figure 5a ) are provided on a substantially XZ-direction end face 121 of the mounting arm 12.

[0032] As shown in Figures 4 to 6b the headlight housing 20 includes a housing body 21 that houses electronic components and a mounting plate 22 that extends from the housing body 21 toward the bumper skeleton 10. The mounting plate 22 is provided with a positioning pin 24 that matches the positioning hole 13 and a second fixing portion 25 that is fixedly connected to the first fixing portion 14. More specifically, the positioning pin 24 integrally protrudes from one side of the mounting plate 22, and in the shown embodiment, both the first fixing portion 14 and the second fixing portion 25 are provided as through holes, so that the bumper skeleton 10 and the headlight housing 20 are fixedly connected by screws that sequentially pass through the first fixing portion 14 and the second fixing portion 25.

[0033] The following will further describe the positioning hole 13 in detail.

[0034] As shown in Figure 5a and Figure 5b the positioning hole 13 includes an opening 131 and a limiting groove 132 that communicate with each other and includes at least one guiding portion 133. The insertable area of the opening 131 is preferably larger than the cross-sectional area of the positioning pin 24, so that the positioning pin 24 can conveniently enter the positioning hole 13 by being inserted into the opening 131 and can enter and be snap-fitted into the limiting groove 132 along the guiding portion 133 from the opening 131.

[0035] The positioning hole 13 includes an upper edge 135, a front edge 136, a rear edge 137, an arcuate lower edge 138, and a guiding portion 133.

[0036] InFigure 5b In the illustrated embodiment, the front edge 136 includes a vertical edge 1361 extending substantially along the Z direction and a horizontal edge 1362 extending slightly outwardly in the Y direction from the lower end of the vertical edge 1361. The rear edge 137 includes an upper segment 1371 and a lower segment 1372. The upper segment 1371 includes a horizontal edge 1371a extending slightly outwardly in the Y direction from the rear end of the upper edge 135 and an inclined edge 1371b extending downwardly and slightly forwardly relative to the Z direction from the horizontal edge 1371a. The arrangement of the inclined edge 1371b can enlarge the area of the opening 131, making it easier for the positioning pin 24 to enter the opening 131, and at the same time can also play a guiding role.

[0037] The guiding portion 133 is an arc-shaped edge connecting the horizontal edge 1362 of the positioning hole 31 and the front end of the arc-shaped lower edge 138. The top of this arc-shaped edge forms an abutting edge 1331 extending substantially along the X direction to be able to abut and support the positioning pin 24 before the positioning pin 24 enters the limiting groove 132, and the bottom of this arc-shaped edge forms a limiting edge 1333 extending substantially along the Z direction.

[0038] Thus, in the positioning hole 31, the upper edge 135, the front edge 136, the upper segment 1371 of the rear edge, and the abutting edge 1331 define the opening 131, while the arc-shaped lower edge 138, the lower segment 1372 of the rear edge, and the limiting edge 1333 define the limiting groove 132.

[0039] As Figures 6a to 7 shown, the size of the limiting groove 132 matches the diameter of the positioning pin 24. Thus, when the positioning pin 24 enters the limiting groove 132, the bottom of the positioning pin 24 supports and abuts against the arc-shaped lower edge 138 (or there is a tiny gap between them), and the front and rear sides of the positioning pin 24 respectively abut against the limiting edge 1333 and the lower segment 1372 of the rear edge (or there are tiny gaps), thereby restricting the displacement of the positioning pin 24 in the X direction.

[0040] When assembling the vehicle body structure A, first move the headlight housing 20 backward relative to the bumper skeleton 10 in the X direction to a predetermined position, and make the positioning pin 24 enter the positioning hole 13 and lap onto the abutting edge 1331 by inserting it into the opening 131 in the Y direction. At this time, due to the influence of the surrounding environmental components, the headlight housing 20 cannot continue to move backward in the X direction; then push or pull the mounting arm 12. Due to the elastic deformation of the mounting arm 12 relative to the skeleton body 11, the positioning pin 24 can slide downward along the guiding portion 133 and snap into the limiting groove 132; finally, align the first fixing portion 14 with the second fixing portion 25 and fix them to each other by screws to fix the headlight housing 20 to the bumper skeleton 10.

[0041] The technical content and features of the present invention have been disclosed above. However, it can be understood that under the creative concept of the present invention, those skilled in the art can make various changes and improvements to the above-disclosed concept, but all fall within the protection scope of the present invention.

[0042] The description of the above embodiments is exemplary rather than restrictive, and the protection scope of the present invention is determined by the claims.
