Description
Technical Field
[0001] This utility model relates to the field of automotive body structure technology, specifically to a modular rear fog light mounting structure for a bus. Background Technology
[0002] The existing rear fog light mounting structures for buses mainly employ two technical solutions: The first uses a fiberglass outer skin panel, combined with multiple independent L-shaped iron brackets for fixation. The fog lights are then bolted to these brackets for secure mounting. This simple bracket-based method is functionally limited; the brackets only connect the fog lights and cannot effectively contribute to the overall load transfer and stress distribution of the vehicle body. When the vehicle body is subjected to external impact, the brackets in certain areas can easily deform, damaging the fog lights and making them difficult to disassemble and repair. The second method involves directly welding the fog light mounting base to the iron outer skin panel. This method results in weld points on the outer surface of the iron skin panel, severely affecting the appearance quality. These weld points require rework and grinding, reducing production efficiency and increasing processing costs. Utility Model Content

The mounting plate has several adhesive grooves on its front end face, with each groove spaced along the outer periphery of the front end face. Expanding adhesive is provided in each groove, and when the mounting plate is attached to the inner surface of the rear fog light outer panel, the expanding adhesive secures the mounting plate and the rear fog light outer panel together. The mounting plate has several mounting holes for mounting the fog light. A reinforcing plate has its upper edge welded to the side of the rear fog light outer panel and its lower edge welded to the rear end face of the mounting plate, so that the reinforcing plate is suspended above the inner surface of the rear fog light outer panel.
[0005] Preferably, the rear fog light outer panel has a side connection port on the left side and an upper connection port on the upper side; the first connecting part includes a first skirt erected at the side connection port, and the first skirt is screwed to the rear bottom plate by a bolt assembly; the second connecting part includes a second skirt erected at the upper connection port, and the second skirt is screwed to the rear side plate by a bolt assembly.
[0006] Preferably, the extension direction of the first skirt is parallel to the end face of the side connection port, and the extension length of the first skirt is at least half the length of the side connection port.
[0007] Preferably, the second connecting portion further includes a third skirt disposed at the upper connecting port, the third skirt and the second skirt being respectively located at the left and right ends of the upper connecting port; the third skirt is used to be screwed and fixed to the rear side plate and the reinforcing plate by bolt assembly.

[0014] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:
[0015] This utility model provides a modular rear fog light mounting structure for buses. Its structure is simple, easy to implement, and low-cost, solving the problems of existing fog light mounting structures on the rear assembly of buses, such as inability to participate in vehicle load transfer and the presence of weld points on the exterior. The technical solution of this utility model features a modular design for the rear fog light mounting structure, which is detachably connected to the rear assembly of the bus. When the rear of the vehicle is impacted and the area deforms, only the damaged module can be partially disassembled and replaced, avoiding the huge waste of replacing the entire rear assembly and significantly reducing maintenance costs and time. Secondly, the mounting plate is glued to the rear fog light outer plate with expanding adhesive, abandoning traditional welding methods and eliminating weld point defects on the surface, ensuring an aesthetically pleasing appearance. This eliminates the need for subsequent tedious grinding and rework processes, improving production efficiency and product qualification rate. Furthermore, this utility model… The design incorporates a reinforcing plate, with its upper and lower edges welded to the side of the rear fog light outer panel and the mounting plate, respectively. The central body of the reinforcing plate remains suspended relative to the inner surface of the rear fog light outer panel, forming a stable triangular support structure. This allows the mounting plate to directly and efficiently transfer the impact force to the edge of the rear fog light outer panel through the reinforcing plate, avoiding direct impact on the central area of the fog light outer panel skin and effectively preventing skin deformation. In this way, the mounting plate smoothly transfers and diffuses the load through the rear fog light outer panel to the entire vehicle body, using the overall vehicle structure to resist external impact forces, greatly enhancing the overall rigidity, impact resistance, and safety of the rear assembly.

[0035] Please see Figures 1 to 6 .
[0036] This embodiment provides a modular rear fog light mounting structure for a bus. Its structure is simple, easy to implement, and low in cost, solving problems such as the inability of existing fog light mounting structures on the rear assembly of buses to participate in vehicle load transfer and the presence of weld points on the exterior. For the technical solution of this utility model, see [link to relevant documentation]. Figure 1 and Figure 2 The modular rear fog light mounting structure of the bus in this embodiment is fixedly installed in relation to the rear assembly of the bus; see [link / reference]. Figures 3 to 6 The rear fog light mounting structure of the bus mainly includes a rear fog light outer panel 1, a mounting plate 2, and a reinforcing plate 3, all of which are stamped parts;
[0037] In this embodiment, the rear fog light outer panel 1, see... Figure 3 It has a side connection port 1a on its left side and an upper connection port 1b on its upper side. The rear fog light outer panel 1 also has a first connecting part and a second connecting part. Specifically, the first connecting part includes a first skirt 11 erected at the side connection port 1a. The first skirt 11 is mainly connected to the rear bottom plate A1 (see...) via bolt assemblies. Figure 1 , Figure 2 The second connecting part includes a second skirt 12 erected on the upper connecting port 1b, and the second skirt 12 is correspondingly provided on the left and right ends of the third skirt 13 at the upper connecting port 1b, wherein the second skirt 12 is connected to the rear side panel A2 (see bolt assembly) by bolt assembly. Figure 1 , Figure 2 To ensure the connection strength between the upper connection port 1b and the rear side panel A2, the third skirt 13 is screwed to the rear side panel A2 and the reinforcing plate 3 (the third skirt 13, the rear side panel A2, and the reinforcing plate 3 overlap each other, and the bolt assembly passes through the three for fixation) via a bolt assembly. In this way, the second skirt 12 and the third skirt 13 achieve a two-point fixed connection with the rear side panel A2, which greatly enhances the positioning stiffness and resistance to torsional deformation at the connection point.
[0038] In this embodiment, see Figure 3The first skirt 11 extends in a direction parallel to the end face of the side port 1a, and the extension length of the first skirt 11 is at least half the length of the side port 1a. This design significantly ensures the connection contact area between the two.
[0039] In this embodiment, mounting plate 2, see... Figure 3 Its front end face is fitted to the inner surface of the rear fog light outer panel 1 (the outer surface of the rear fog light outer panel 1 is the exterior part), and the through hole 21 of the mounting plate 2 corresponds to the lamp hole 14 of the rear fog light outer panel 1; see also Figure 3 and Figure 6 The front end face of the mounting plate 2 is provided with several elongated adhesive grooves 22. Each adhesive groove 22 is spaced along the outer periphery of the front end face. Expanding adhesive is provided in the adhesive groove 22. The expanding adhesive fills the elongated adhesive groove 22 and adheres to the inner surface of the rear fog light outer panel 1. Specifically, when the mounting plate 2 is adhered to the inner surface of the rear fog light outer panel 1, the mounting plate 2 and the rear fog light outer panel 1 are fixedly glued after the expanding adhesive has cured.
[0040] In this embodiment, see Figure 6 The mounting plate 2 has several mounting holes 23 for mounting fog lights 5, and each mounting hole 23 is pre-embedded with a pre-embedded nut 24, see [reference]. Figure 5 , 24 pre-embedded nuts are used for bolt connection of fog lights 5.
[0041] In this embodiment, the limiting component 4, in conjunction with [see reference 4] Figure 3 and Figure 4 The limiting component 4 includes a first wall edge 41 integrally formed on the rear fog light outer panel 1 and a second wall edge 42 integrally formed below the mounting plate 2. When the mounting plate 2 and the rear fog light outer panel 1 are glued and fixed, the first wall edge 41 is stacked on the outside of the second wall edge 42 and the two are welded together. In this embodiment, the height of the first wall edge 41 is higher than the height of the second wall edge 42, so that the first wall edge 41 can completely accommodate and cover the second wall edge 42, ensuring the welding contact area between the two and preventing the rear fog light outer panel 1 from detaching.
[0042] This embodiment also includes a reinforcing plate 3, which can be referred to in conjunction with the above. Figure 3 and Figure 6The reinforcing plate 3 has a stepped bending structure in its cross-section, which significantly improves its bending and torsional stiffness. The upper edge of the reinforcing plate 3 is welded to the side of the rear fog light outer panel 1, and the lower edge is welded to the rear end face of the mounting plate 2, so that the reinforcing plate 3 is suspended above the inner surface of the rear fog light outer panel 1. In this embodiment, the suspended arrangement of the reinforcing plate 3 is mainly to reduce the contact area between the main body of the reinforcing plate 3 and the rear fog light outer panel 1, so as to form a triangular support. This allows the mounting plate 2 to directly and efficiently transmit the impact force to the edge of the rear fog light outer panel 1 through the reinforcing plate 3, avoiding direct impact on the central area of the fog light 5 outer panel skin and effectively preventing skin deformation.
[0043] The working principle and usage process of this utility model:
[0044] Before installing the rear panel assembly and the rear fog light 5 mounting structure of the bus,
[0045] First, stamping processes are used to prepare stamped products such as... Figure 4 The rear fog light outer panel 1, mounting plate 2, and reinforcing plate 3;
[0046] Second, assemble the rear fog light outer panel 1, mounting plate 2, and reinforcing plate 3 into modules, see [link to module]. Figure 6 Spray expanding adhesive into each of the adhesive grooves 22 of the mounting plate 2, and position the mounting plate 2 (which also has positioning holes for the positioning clamps) and the rear fog light outer plate 1 using external positioning clamps. See [link to documentation]. Figure 3 This allows the front end of the mounting plate 2 to precisely cover the corresponding position on the inner surface of the rear fog light outer panel 1. Then, the expanding adhesive in the adhesive groove 22 is cured, thus fixing the mounting plate 2 to the inner surface of the rear fog light outer panel 1.
[0047] Third, see Figure 3 To prevent the expansion adhesive from loosening and falling off due to long-term use, the second wall edge 42 folded down below the mounting plate 2 is welded and fixed to the first wall edge 41 of the rear fog light outer plate 1. In this way, the force acting on the expansion adhesive can be dispersed and transmitted to the rear fog light outer plate 1 through the adhesion of the first wall edge 41 and the second wall edge 42, and the service life of the expansion adhesive can also be improved.
[0048] Fourth, see Figure 3The reinforcing plate 3 is placed between the rear fog light outer panel 1 and the mounting plate 2. The upper edge of the reinforcing plate 3 is welded to the side of the rear fog light outer panel 1, and the lower edge is welded to the rear end face of the mounting plate 2. At this time, the reinforcing plate 3 will be suspended above the inner surface of the rear fog light outer panel 1, and the middle area of the reinforcing plate 3 will not contact the inner surface area of the rear fog light outer panel 1. In this way, the force on the mounting plate 2 can be directly transmitted and distributed to the side of the rear fog light outer panel 1 through the reinforcing plate 3, and then distributed from the side to the entire rear assembly, thus completing the modular assembly of the entire rear fog light 5 mounting structure.
[0049] Fifth, see Figure 1 and Figure 2 The entire module's rear fog light 5 mounting structure is detachably and securely installed to the bus's rear assembly; firstly, in conjunction with the reference... Figure 3 The side connection port 1a of the mounting plate 2 is aligned with the rear bottom plate A1, and the first skirt 11 of the side connection port 1a of the mounting plate 2 is screwed and fixed to the rear bottom plate A1 using a bolt assembly (bolts and nuts). Then, the upper connection port 1b of the rear fog light outer plate 1 is aligned with the rear side plate A2, and the second skirt 12 and the third skirt 13 of the upper connection end of the mounting plate 2 are screwed and fixed to the rear side plate A2 using a bolt assembly (bolts and nuts). In this way, the rear fog light 5 mounting structure and the rear assembly of the bus can be detachably and fixedly installed.
[0050] Sixth, see Figure 5The assembly of the fog light 5 with the rear fog light 5 mounting structure of the bus is carried out. The fog light 5 is set behind the mounting plate 2 and screwed with bolts and pre-embedded nuts 24 behind the mounting holes to fix the fog light 5 to the rear of the mounting plate 2. Therefore, in this utility model, the rear fog light 5 mounting structure adopts a separate modular design. It is detachably connected to the rear assembly of the bus. When the rear of the vehicle is impacted and the area is deformed, only the damaged module can be partially disassembled and replaced, avoiding the huge waste of replacing the entire rear assembly and significantly reducing maintenance costs and time. Secondly, the mounting plate 2 and the rear fog light outer plate 1 are glued together with expanding adhesive, abandoning the traditional welding process, eliminating the defects of visible weld points on the surface, ensuring a beautiful appearance, and thus saving the subsequent tedious grinding and rework process, improving production efficiency and product qualification rate. Next, this utility model is designed with The reinforcing plate 3 has its upper and lower edges welded to the side of the rear fog light outer panel 1 and the mounting plate 2, respectively. Its central body is suspended relative to the inner surface of the rear fog light outer panel 1, forming a stable triangular support. This allows the mounting plate 2 to directly and efficiently transfer the impact force to the edge of the rear fog light outer panel 1 through the reinforcing plate 3, avoiding direct impact on the center area of the fog light 5 outer panel skin and effectively preventing skin deformation. In this way, the mounting plate 2 smoothly transfers and diffuses the load through the rear fog light outer panel 1 to the entire vehicle body, so that the entire vehicle body can resist external impact forces, greatly enhancing the overall rigidity, impact resistance and safety of the rear assembly.
[0051] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
