Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0030] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0031] The headlight of a car is one of the most critical appearance parts of the front face of the car. The headlights are matched with multiple appearance parts such as the engine hood, fenders and front bumper with gaps. However, due to the errors in the manufacturing process, it is difficult for the headlight assembly accuracy to meet the appearance requirements. Usually, during the development of a car, multiple rounds of real car matching and adjustment of product molds are required to meet the appearance requirements. The adjustment of product molds requires a lot of manpower and material resources, and the adjustment cycle is long. Therefore, it is very important to develop a headlight mounting structure that can quickly and conveniently adjust its accuracy. At present, a headlight mounting structure integrates the fixing points of surrounding appearance parts, reduces the dimension chain, and thus improves the accuracy. However, although the accuracy of the above-mentioned headlight mounting structure has been improved, the mounting structure itself cannot be adjusted, and the assembly accuracy of the headlight cannot be guaranteed. In order to solve the above problems, the embodiment of the utility model proposes a headlight mounting bracket and a car.

[0033] Specifically, the headlight mounting bracket is used for mounting headlights in automobiles. The first bracket 3 and the second bracket 4 are both welded to the connecting member 1, and the first bracket 3 and the second bracket 4 are specifically welded to the connecting member 1 by spot welding. The first bracket 3 has a fifth welding surface, which is welded to the first welding surface 11. The second bracket 4 has a sixth welding surface, which is welded to the second welding surface 12. Figure 5 The fifth welding surface can be welded to the first welding surface 11 through two welding points, and the sixth welding surface can be welded to the second welding surface 12 through three welding points. The automobile coordinate system includes an X-axis, a Y-axis and a Z-axis. The automobile coordinate system specifically refers to Figure 2 The coordinate system shown in the figure, wherein the X direction is specifically the length direction of the car, the Y direction is specifically the width direction of the car, and the Z direction is specifically the height direction of the car. The first reference surface is the XZ plane in the car coordinate system, and the first welding surface 11 and the second welding surface 12 are both parallel to the XZ plane. The second reference surface is the YZ plane in the car coordinate system, and the first mounting surface 31 and the second mounting surface 41 are both parallel to the YZ plane. A weight reduction hole 17 is provided on the connector 1.

[0034] In the embodiment of the utility model, the headlight mounting bracket includes a connecting member 1, a first bracket 3 and a second bracket 4, which is a split structure.

[0035] In the embodiment of the utility model, the positions of the first bracket 3 and the second bracket 4 are adjustable when they are welded to the connecting member 1, so as to absorb manufacturing errors and ensure that the first mounting surface 31 and the second mounting surface 41 are parallel to the second reference surface, so that the first mounting surface 31 and the second mounting surface 41 meet the accuracy requirements, thereby ensuring the assembly accuracy of the headlight. In addition, in the embodiment of the utility model, the positions of the first bracket 3 and the second bracket 4 can be adjusted by a welding fixture without changing the structures of the connecting member 1, the first bracket 3 and the second bracket 4 themselves, and the adjustment is fast and convenient.

The position of the headlight can be adjusted during the process of assembling it to the headlight mounting bracket. When adjusting the position, the headlight can be translated and rotated on the first mounting surface 31 and the second mounting surface 41 to ensure that the positions of the first through hole and the second through hole on the headlight correspond to the positions of the first connection hole 32 and the second connection hole 42, respectively, thereby ensuring the assembly accuracy of the headlight.

[0047] Specifically, the shapes of the first fixing hole 14, the second fixing hole 21, the third fixing hole 15, the first mounting hole, the second mounting hole and the third mounting hole are all circular. The size of the first fixing hole 14 is larger than the size of the first mounting hole, specifically, the diameter of the first fixing hole 14 is larger than the diameter of the first mounting hole, and the difference between the diameters can be set according to actual needs, such as the difference can be within 1 mm. The size of the second fixing hole 21 is larger than the size of the second mounting hole, specifically, the diameter of the second fixing hole 21 is larger than the diameter of the second mounting hole, and the difference between the diameters can be set according to actual needs, such as the difference can be within 1 mm.
