Description

Technical Field

[0001] This invention belongs to the field of automobile manufacturing technology, specifically a front bumper mounting bracket, positioning method, and automobile. Background Technology

[0002] As consumers' aesthetic and quality requirements continue to rise, exterior quality has become one of the key factors they prioritize. When customers consider buying a car, their first focus is on the vehicle's appearance. The front of the car is the first thing that catches the consumer's eye. Key components such as the front bumper and headlights are assembled in the front of the car, and their coordination is crucial, forming the core of the front-end's overall look and directly affecting its quality.

[0003] Therefore, how to quickly and effectively control the gap and surface difference between the front bumper and the headlights has always been one of the key concerns for OEMs.

[0004] Existing front bumpers are generally fixed to the front-end module directly using bolts and locating pins. For example, in Chinese invention patent CN 111791820 A, entitled "Center Support for Front Bumper of Electric Vehicle and Automobile," the main locating pin, the auxiliary locating pin, the mounting pin, and each bolt mounting component are provided with a bolt mounting hole. These bolt mounting holes are used to connect to the front-end module via bolts, and each bolt mounting hole is for Z-axis tightening to control the Z-axis degree of freedom. This solution can solve the problem of Z-axis flipping during the assembly of the center support, but it cannot effectively control the gap and surface difference between the front bumper and the headlights.

[0005] Chinese utility model patent CN 218400463 U, entitled "Height-Adjustable Front Bumper and Automobile," discloses a height adjustment component that allows for easy adjustment of the front bumper's vertical height until the gap between the upper edge of the front bumper and the lower edge of the hood is adjusted to a preset gap. This ensures surface matching between the front surfaces of the front bumper and the hood, reducing the difficulty of assembling the front bumper and hood. However, the additional height adjustment components in this patent increase manufacturing costs and require more work for installers.

[0006] In summary, how to ensure the stability of the connection between the headlights and the front bumper while controlling the surface gap between them to improve the appearance matching quality and reduce the workload of manual matching and adjustment is a problem that urgently needs to be solved in the existing technology. Summary of the Invention

[0007] The purpose of this invention is to provide a front bumper mounting bracket, positioning method, and automobile, aiming to solve the problem in the prior art of ensuring the stability of the connection between the headlight and the front bumper while controlling the surface difference of the appearance gap between the headlight and the front bumper, thereby improving the appearance matching quality and reducing the amount of manual matching and adjustment work.

[0008] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0009] The first aspect of the present invention provides a front bumper mounting bracket.

[0010] A front bumper mounting bracket includes a bracket body disposed between a headlight and a front bumper. The bracket body includes a first mounting surface, a second mounting surface, and a third mounting surface that are interconnected. The first mounting surface and the second mounting surface are respectively disposed on the upper and lower sides of the third mounting surface, and the first mounting surface and the second mounting surface are disposed on the same side. The first mounting surface and the second mounting surface are used to connect a front-end module, and the third mounting surface is used to connect a bumper-side mounting bracket.

[0011] As an alternative technical solution, the connection positions of the first mounting surface and the front-end module, the connection positions of the second mounting surface and the front-end module, and the connection positions of the third mounting surface and the side mounting bracket of the bumper are arranged in a triangular pattern.

[0012] As an alternative technical solution, the back of the third mounting surface is provided with multiple recesses, and each recess is provided with a first Z-direction limiting rib on its upper side; the headlight housing is provided with multiple protrusions, and the first Z-direction limiting rib is used to fit against the upper surface of the protrusion; Y-direction limiting ribs are also provided on both sides of the recesses near the first mounting surface, and the Y-direction limiting ribs are used to fit against the side of the corresponding protrusion.

[0013] As an alternative technical solution, the recessed platform is positioned correspondingly to the protruding platform.

[0014] As an alternative technical solution, the upper part of the third mounting surface is provided with multiple limiting holes, and the front bumper is provided with multiple limiting hooks, which are engaged and fixed with the limiting holes.

[0015] As an optional technical solution, each of the limiting holes is provided with a second Z-direction limiting rib on both sides, and the upper surface of the second Z-direction limiting rib abuts against the front bumper.

[0016] As an alternative technical solution, the back of the support body is provided with multiple reinforcing ribs.

[0017] As an optional technical solution, the first mounting surface and the front-end module, the second mounting surface and the front-end module, and the third mounting surface and the bumper side mounting bracket are all bolted connections.

[0018] A second aspect of the present invention provides an automobile.

[0019] An automobile includes a front bumper mounting bracket as described in the first aspect.

[0020] A third aspect of the present invention provides a method for positioning a front bumper mounting bracket.

[0021] A method for positioning a front bumper mounting bracket as described in the first aspect includes the following steps:

[0022] Connect the first and second mounting surfaces of the bracket body to the front-end module, and connect the third mounting surface to the side mounting bracket of the bumper.

[0023] Install the multiple protrusions on the headlight housing one by one with the multiple recesses on the back of the third mounting surface, so that the first Z-direction limiting rib on the upper side of the recess is in contact with the upper surface of the protrusion, and the Y-direction limiting ribs on both sides inside the recess are in contact with the side of the corresponding protrusion.

[0024] The multiple limiting hooks on the front bumper are respectively engaged and fixed with the corresponding limiting holes, and the upper surface of the second Z-direction limiting rib is abutted against the front bumper.

[0025] During the positioning process, by processing the first Z-direction limiting rib, the Y-direction limiting rib, and the second Z-direction limiting rib to achieve different lengths or heights, the relative Z-direction positions of the bracket body and the headlight, the relative Y-direction positions of the bracket body and the headlight, and the relative Z-direction positions of the front bumper and the headlight are controlled respectively.

[0026] The present invention has the following beneficial effects:

[0027] 1. This invention provides a front bumper mounting bracket, a positioning method, and a vehicle. The front bumper mounting bracket is designed with three mounting surfaces. The first and second mounting surfaces are respectively located on the upper and lower sides of the third mounting surface. The first and second mounting surfaces are connected to the front-end module, and the third mounting surface is connected to the bumper side mounting bracket. This improves the connection method of the front bumper mounting bracket in the prior art, which is beneficial to improving the installation stability of the front bumper mounting bracket. Moreover, the two sides are respectively connected and fixed to the front-end module with higher rigidity and more stable quality and the bumper side mounting bracket. The open design in the prior art has been changed to a closed design, which effectively reduces the sagging phenomenon of the headlight front bumper due to weight. This is more conducive to the quality control of the vehicle's front face matching and ensures the consistency of the vehicle's front face quality.

[0028] 2. During the positioning process, by processing the first Z-direction limiting rib, the Y-direction limiting rib, and the second Z-direction limiting rib with different lengths or heights, the relative Z-direction positions of the bracket body and the headlight, the relative Y-direction positions of the bracket body and the headlight, and the relative Z-direction positions of the front bumper and the headlight are controlled respectively, thereby controlling the appearance gap and surface difference fit between the headlight and the front bumper and improving the appearance matching quality.

[0029] 3. Because the relative positions of the headlights and the front bumper are stably connected, the overall appearance quality consistency of the front face can be effectively controlled, while reducing the amount of manual matching and adjustment work and improving efficiency.

[0030] 4. This invention does not require the introduction of an additional height adjustment mechanism, which can effectively control the processing and manufacturing costs.

[0031] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] As described in the background section above, in existing technical solutions, the front bumper 6 mounting bracket often adopts an open design, that is, the bracket body 1 is not simultaneously connected to the front module 4 and the bumper side mounting bracket 3, resulting in some room for improvement in the stability of the headlight 2 and the front bumper 6 connected to the bracket body 1; in addition, existing solutions cannot effectively control the gap and surface difference between the front bumper 6 and the headlight, and the final quality of the car front face outer tube cannot be guaranteed.

[0045] Therefore, how to ensure the stability of the connection between the headlight 2 and the front bumper 6 while controlling the surface gap between the headlight 2 and the front bumper 6, so as to improve the appearance matching quality and reduce the workload of manual matching and adjustment, is an urgent problem to be solved in the existing technology.

[0046] To improve the aesthetic appearance of the front bumper 6 and headlight 2, a specific embodiment of the present invention provides a front bumper 6 mounting bracket, which can be applied to automobile manufacturing and installation. This front bumper 6 mounting bracket is located between the front bumper 6 and the headlight 2, connecting the front bumper 6 and the headlight 2 together and fixing their relative positional relationship. Simultaneously, both sides of the front bumper 6 mounting bracket are connected to rigid components such as the vehicle front-end module 4 and the bumper side mounting bracket 3, forming a closed-off design effect. This improves the rigidity and stability of the connection between the headlight and the bumper, making it less prone to sagging.

[0047] In addition, by setting multiple first Z-direction limiting ribs 110, Y-direction limiting ribs 109 and second Z-direction limiting ribs 112, the Z-direction relative position of the bracket body 1 and the headlight 2, the Y-direction relative position of the bracket body 1 and the headlight 2, and the Z-direction relative position of the front bumper 6 and the headlight 2 are controlled, ensuring the consistency of the appearance quality of the front face of the car.

[0048] Please see Figure 1 The image shows a front view of the front bumper 6 mounting bracket. In this embodiment, the front bumper 6 mounting bracket includes a bracket body 1, which is disposed between the headlight 2 and the front bumper 6. The bracket body 1 includes a first mounting surface 101, a second mounting surface 103, and a third mounting surface 105 connected to each other. The first mounting surface 101 and the second mounting surface 103 are respectively disposed on the upper and lower sides of the third mounting surface 105, and the first mounting surface 101 and the second mounting surface 103 are disposed on the same side. Figure 4 As shown, the first mounting surface 101 and the second mounting surface 103 are used to connect the front-end module 4, and the third mounting surface 105 is used to connect the bumper side mounting bracket 3.

[0049] The front bumper 6 mounting bracket in this embodiment is located between the headlight 2 and the front bumper 6, and has a total of 3 mounting surfaces. The X-axis position of the front bumper mounting bracket in the front face system is controlled by the 3 mounting surfaces.

[0050] Mounting holes are designed on the three mounting surfaces, such as... Figure 1 As shown, the two mounting surfaces on the left are the first mounting surface 101 and the second mounting surface 103. The first mounting surface 101 and the second mounting surface 103 are arranged vertically, with one on each side, and both are located on the same side of the middle mounting surface (the third mounting surface 105). The first mounting surface 101 and the second mounting surface 103 are mounted on the front module 4 assembly by mounting bolts. The third mounting surface 105 is connected to the front bumper 6 side mounting bracket 3 by bolts. The three mounting surfaces are used to control the X-direction position of the bumper mounting bracket in the front of the car.

[0051] It is understood that, for ease of installation, the connections between the first mounting surface 101 and the front-end module 4, the second mounting surface 103 and the front-end module 4, and the third mounting surface 105 and the bumper side mounting bracket 3 are all bolted. A first mounting hole 102 is provided on the first mounting surface 101, and a second mounting hole 104 is provided on the second mounting surface 103. The first mounting surface 101 and the second mounting hole 104 are respectively fixed to the front-end module 4 through the cooperation of the mounting bolts. A third mounting hole 106 is provided on the third mounting surface 105, and the third mounting surface 105 is connected and fixed to the bumper side mounting bracket 3 through the cooperation of the third mounting hole 106 and the mounting bolts.

[0052] The first mounting surface 101, the second mounting surface 103, and the third mounting surface 105 are arranged in a triangle, which helps to improve the installation stability of the front bumper mounting bracket. Moreover, the two sides are respectively connected and fixed to the front module 4 with higher rigidity and more stable quality and the bumper side mounting bracket 3. The open design is changed to a closed design, which effectively reduces the sagging phenomenon of the headlight front bumper caused by weight. It is more conducive to the quality control of the matching of the front face of the car and ensures the consistency of the quality of the front face of the car.

[0053] The middle section of the front bumper mounting bracket is mainly used to establish a connection with the headlights 2 and the front bumper 6, controlling the relative position of the headlights 2 and the front bumper 6, thereby controlling the surface gaps and mismatches between the headlights 2 and the front bumper 6, and improving the overall appearance matching quality. At the same time, because the relative position of the headlights 2 and the front bumper 6 is stably connected, the overall consistency of the front appearance quality can be effectively controlled, reducing the amount of manual matching and adjustment work and improving efficiency.

[0054] Specifically, such as Figure 3 The image shown is a rear view of the front bumper 6 mounting bracket in this embodiment. The middle section of the front bumper 6 mounting bracket has three recessed platforms 108 on its rear side. Each recessed platform 108 has three first Z-direction limiting ribs 110 on its upper part. Correspondingly, the headlight 2 housing has three protrusions 201. The first Z-direction limiting ribs 110 on the upper part of the inner side of the three recessed platforms 108 of the front bumper 6 mounting bracket respectively fit and match the upper surface of the corresponding headlight 2 protrusions 201. Figure 5 As shown, it is used to control the Z-direction position of the front bumper mounting bracket 1 under the front of the car, and at the same time control the Z-direction relative position of the front bumper mounting bracket 1 and the headlight 22.

[0055] like Figure 3 As shown, the innermost recessed platform 108 of the front bumper 6 mounting bracket is also provided with Y-direction limiting ribs 109 on both sides, which fit against the two sides of the innermost protrusion 201 of the headlight 2 protrusion 201, as shown in the cross-section. Figure 6 As shown, it is used to control the relative position of the front bumper mounting bracket and the headlight 2 in the Y direction, and also controls the Y direction position of the front bumper mounting bracket under the front of the car.

[0056] Furthermore, the height of the Z-direction limiting rib and Y-direction limiting rib 109 in the front bumper mounting bracket recess 108 is adjustable, which is beneficial to control the front face matching state, especially the gap surface difference between the headlight 2 and the front bumper 6.

[0057] At this point, the relative position of the front bumper 6 mounting bracket under the car's front-end system is completely determined and controlled, and the relative position of the front bumper mounting bracket 1 and the headlight 22 is also controlled.

[0058] It can be understood that the recessed platform 108 and the protruding platform 201 are positioned correspondingly. The front-end module 4 and the bumper side mounting bracket 3 are both connected to the vehicle body 5.

[0059] The main structure at the front of the middle section of the front bumper mounting bracket is for establishing a connection with the front bumper, specifically:

[0060] like Figure 2 As shown, the upper part of the middle section of the front bumper mounting bracket has four limiting holes 107, and corresponding to four limiting hooks 601 designed on the front bumper body 6, the limiting hooks 601 are inserted into the corresponding limiting holes 107, such as... Figure 7 As shown, the two are snapped together and fixed, controlling the relative position of the front bumper 6 and the headlight 2 in the X direction;

[0061] Furthermore, a second Z-direction limiting rib 112 is arranged on both sides of the limiting hole 107. The upper surface of the second Z-direction limiting rib 112 abuts against the front bumper 6 and holds the front bumper 6 in place, thereby controlling the Z-direction relative position between the front bumper 6 and the headlight 2.

[0062] Furthermore, the Z-direction height of the second Z-direction limiting rib 112 is adjustable, so the Z-direction relative position of the front bumper 6 body and the headlight 2 can be adjusted according to the actual vehicle appearance quality, which is convenient and quick.

[0063] Furthermore, several reinforcing ribs 111 are evenly arranged on the rear side of the front bumper bracket 6 to enhance the rigidity of the bumper mounting bracket itself and ensure its precision stability and consistency.

[0064] like Figure 4 As shown, the front bumper 6 and the headlight 2 are connected together via the front bumper 6 mounting bracket, and the connection between the headlight 2 and the front bumper 6 is fully established through the front bumper mounting bracket. This effectively controls the relative position of the front bumper 6 and the headlight 2, and the clearance and surface difference fit between them. Simultaneously, the two sides of the bumper mounting bracket are connected to rigid components such as the front-end module 4 and the bumper side mounting bracket 3, which have good rigidity and stability. This effectively prevents the headlight 2 and the front bumper 6 from sagging, improves the stability of the local area fit, and enhances the overall quality of the front-end appearance, ensuring the consistency of the car's front-end appearance.

[0065] It can be understood that the adjustable length or height of the first Z-direction limiting rib 110, Y-direction limiting rib 109, and second Z-direction limiting rib 112 mentioned above in this embodiment refers to controlling the Z-direction relative position between the bracket body 1 and the headlight 2, the Y-direction relative position between the bracket body 1 and the headlight 2, and the Z-direction relative position between the front bumper 6 and the headlight 2 by processing the first Z-direction limiting rib 110, Y-direction limiting rib 109, and second Z-direction limiting rib 112 to achieve the same result. It does not mean that the structure of the first Z-direction limiting rib 110, Y-direction limiting rib 109, and second Z-direction limiting rib 112 is adjustable.

[0069] Example 3:

[0072] The first mounting surface 101 and the second mounting surface 103 of the bracket body 1 are connected to the front module 4, and the third mounting surface 105 is connected to the bumper side mounting bracket 3.

[0073] Install the multiple protrusions 201 on the housing of the headlight 2 in a one-to-one correspondence with the multiple recesses 108 on the back of the third mounting surface 105, so that the first Z-direction limiting rib 110 on the upper side of the recess 108 fits against the upper surface of the protrusion 201, and the Y-direction limiting ribs 109 on both sides inside the recess 108 fits against the side of the corresponding protrusion 201.

[0074] Multiple limiting hooks 601 on the front bumper 6 are respectively engaged and fixed with the corresponding limiting holes 107, and the upper surface of the second Z-direction limiting rib 112 abuts against the front bumper 6.

[0075] During the positioning process, by processing the first Z-direction limiting rib 110, the Y-direction limiting rib 109 and the second Z-direction limiting rib 112 with different lengths or heights, the relative Z-direction positions of the bracket body 1 and the headlight 2, the relative Y-direction positions of the bracket body 1 and the headlight 2, and the relative Z-direction positions of the front bumper 6 and the headlight 2 are controlled respectively.
