Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a front bumper and fog light mounting structure for automobiles. Background Technology

[0002] Traditional fog lights and daytime running lights are fixed to the vehicle body or bumper, or the front fog light trim panel. Because of the weight and center of gravity of fog lights, there are requirements for installation strength and the location of the installation point. The appearance quality of the bumper should not be affected while ensuring the installation position and strength of the fog lights.

[0003] For example, Chinese patent CN110696713A discloses a car fog light mounting bracket structure, including a fog light mounting bracket body, a spring nut mounting hole, an integrated claw, a fog light mounting hole, a rib buckle mounting hole, and a limiting hole. The fog light mounting bracket body has a fog light mounting hole, and a fog light mounting space containing the fog light cover body is provided in the middle of the fog light mounting bracket body. This method adds a separate adapter bracket, and the bracket itself also needs to be installed on the bumper, which is relatively large and heavy, requiring a large installation space, and the fog light is placed in a relatively central position. Generally, fog lights are used in conditions with poor visibility within 200-50 meters, so from the perspective of shape and lighting requirements, it is desirable to place the fog lights and daytime running lights as close to the sides of the bumper as possible. Due to the parting line within the bumper mold and the appearance quality, it is basically impossible to place the mounting structure close to the sides of the bumper; this imposes certain constraints on the shape and the expansion of the lighting area.

[0004] The structure imposes certain limitations on the shape and fog light arrangement, and requires the separate development of a fog light adapter bracket. Taking advantage of the fact that the shape of the adapter bracket is not restricted, a position on the bumper body that does not affect the appearance of the bumper is found for fastening, and the fog light is wrapped in and secured. In this case, the adapter bracket is very large, with two cavities in a single mold that is symmetrical on both sides, and the mold is also relatively large, resulting in higher mold costs and unit weight. In addition, the adapter bracket itself is fastened to the bumper body by welding, screws, or clips, resulting in more assembly processes and fasteners. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a front bumper and fog light mounting structure for automobiles, which ensures the strength of fog light installation and the appearance of the bumper while being simple in structure and easy to install.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] The car front bumper and fog light mounting structure includes a bumper body and fog lights. The side of the bumper body is provided with a mounting through hole area for fog light mounting. On the non-exterior surface of the bumper body, near the edge of the mounting through hole area, there is a flip-up self-mounted hinge structure. The self-mounted hinge structure is provided with hinge structure fixing holes for fixing the self-mounted hinge structure to the bumper body after flipping and an assembly structure for fixing the fog lights.

[0008] Further:

[0009] The bumper body has a set of positioning posts on a non-exterior surface for screw mounting and fixing the fog lights.

[0010] The integrated hinge structure and the bumper body are an integral structure.

[0011] The assembly structure and the self-contained hinge structure are integrated into one unit.

[0012] The edge of the mounting through hole area of ​​the bumper body is provided with a flange, and the built-in hinge structure is provided at the flange. The flange is provided with stepped holes corresponding to the fixing holes of the hinge structure.

[0013] The assembly structure is a hinge structure screw post with a built-in hinge structure.

[0014] The built-in hinge structure is connected to the bumper body via an integrated connecting rib.

[0015] The hinge structure fixing holes are a set arranged side by side.

[0016] The positioning post includes an auxiliary positioning post and a main positioning post, and the edge of the fog light is provided with a set of lugs that cooperate with the positioning post and the screw post.

[0017] The lug is provided with a groove or convex ring structure that matches the end of the column, and the outer edge of the end of the column is provided with a side rib. The groove or convex ring structure is provided with an opening structure that matches the side rib.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The front bumper and fog light mounting structure of this car is reasonably designed. It utilizes the main body to directly connect to the boss pillar and the hinge structure for self-positioning and fastening. While ensuring the strength of the fog light installation and the appearance of the bumper, it saves one adapter bracket mold and the left and right symmetrical adapter brackets, simplifies the assembly process and reduces the number of assembly fasteners. The front bumper main body mold does not need to add structures such as the slanted top, simplifying the front bumper mold structure. In short, it reduces costs and weight while improving efficiency, which is conducive to the lightweight design of the whole vehicle. Attached Figure Description

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0027] like Figures 1 to 5 As shown, the front bumper and fog light mounting structure of the car includes a bumper body 1 and fog lights 2. The side of the bumper body is provided with mounting through holes a for mounting fog lights. The fog lights 2 are a pair of fog lights on the left and right, and the mounting through holes are a pair of oppositely arranged.

[0028] The bumper body 1 has a flip-up hinge structure 101 on the non-exterior surface near the edge of the mounting through hole area. The hinge structure and the bumper body are an integral structure, that is, the hinge structure is integrated into the bumper body. The hinge structure is connected to the bumper body through an integral connecting rib. The automatic hinge structure can be flipped through the connecting rib and is flipped and fixed on the bumper body after demolding.

[0029] The integrated hinge structure has hinge structure fixing holes 101-2 for fixing the integrated hinge structure to the bumper body after flipping, and an assembly structure for fixing the fog lights; the assembly structure and the integrated hinge structure are integrated into one structure.

[0030] Furthermore, the edge of the mounting hole area of ​​the bumper body is provided with a flange, and the built-in hinge structure is located at the flange. The flange has stepped holes corresponding to the hinge structure fixing holes, which does not affect the appearance. After the built-in hinge structure is flipped over, the hinge structure fixing holes 101-2 and the stepped holes are aligned, and the built-in hinge structure is fixed to the back of the bumper body by screws 3. The assembly structure is the hinge structure screw post 101-1 built into the built-in hinge structure. After the built-in hinge structure is flipped over, the hinge structure screw post corresponds to the fog light, and the fog light is fixed by screws cooperating with the hinge structure screw post.

[0031] The hinge structure has a set of mounting holes arranged side by side; the bumper body has a set of positioning posts on a non-visual surface for screw mounting and fixing the fog lights; both the hinge structure screw posts and positioning posts are boss posts, which work together with the screws to position and fix the fog lights.

[0032] The positioning post includes an auxiliary positioning post 102 and a main positioning post 103. The edge of the fog light is provided with a set of lugs that cooperate with the positioning post and the screw post; preferably, there are three lugs, forming three fixing points b. The lugs are provided with grooves or convex ring structures that are adapted to the end of the post, and the outer edge of the end of the post is provided with side ribs. The grooves or convex ring structures are provided with opening structures that are adapted to the side ribs, thereby restricting the fog light in the X / Z / Y directions.

[0033] A preferred embodiment of the present invention is as follows:

[0034] By using a direct-mount hinge structure in the blank space on the outer side of the bumper, and by determining the weight center position and mounting angle design of the fog light itself, two direct-mount bosses are defined on the non-exterior surface of the bumper. The hinge structure is secured to the bosses on the bumper edge with 4.2mm diameter screws. Without adding adapter brackets, the bumper successfully provides the necessary mounting points for the fog lights, ensuring the installation strength, shape, and fog light layout requirements of the fog lights.

[0035] The bumper body features a built-in hinge structure providing boss pillars. After the mold is reversed, it provides the fog light mounting position. The hinge mounting structure has built-in mounting holes. The bumper flange has two built-in boss pillars, securing the hinge structure. The hinges are fastened to the bumper body with two 4.2mm diameter screws. Two mounting points are directly provided on the non-exterior surface of the bumper. The fog lights are directly fastened to the three boss pillars on the front bumper using three 4.8mm diameter screws, limiting the X-direction. The fog lights have built-in primary positioning, limiting the Z / Y directions through the boss pillar contour. The fog lights also have built-in auxiliary positioning, limiting the Z-direction through the boss pillar contour.

[0036] This invention determines the placement of fog lights by meeting their lighting and styling requirements. Based on the fog lights' center of gravity, strength requirements, and installation location, two mounting points are identified in the bumper's flanged area where aesthetics are not affected. When a third mounting point is not feasible, a hinge mounting structure is designed using the blank space in the bumper's structure. The molds directly collide, eliminating the need for complex mold structures like core pulling or angled tops. The hinge is used to flip the fog lights to the assembly state, securing them with 4.2mm diameter screws to ensure the hinge structure's installation function and strength. The fog lights are directly mounted to the bumper using the provided mounting sheet and three 4.8mm self-tapping screws. This mounting structure successfully reduces the need for separately developing additional adapter brackets and molds, as well as reducing the number of fasteners and welding processes required for the adapter brackets. This directly reduces costs and weight, and solves many situations where structural layout is limited by high aesthetic requirements. In short, it reduces costs and weight while improving efficiency, contributing to the overall lightweight design of the vehicle.

[0037] The above description is merely an illustration of preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0038] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
