[0002] In the automotive manufacturing industry, rearview mirrors are a key component for ensuring driving safety. Their design rationality and advanced manufacturing process directly affect the overall performance, space utilization, and appearance harmony of the vehicle. As core components, the connection method and structural form of the rearview mirror housing and bracket are key considerations in the design process. Traditionally, a split design combining screws and clips is often used, and this design has formed a relatively fixed process mode in long-term production practice.

[0003] However, this split design has many technical problems that urgently need to be solved: First, the assembly process is complicated, requiring multiple steps to connect and fix the shell and bracket, which not only significantly increases the labor and time costs in the production process, but also reduces the overall production efficiency; Second, the assembly process relies on specialized assembly fixtures, which further increases the investment and maintenance costs of production equipment, and also increases the complexity of the production process; Third, the split structure lacks compactness in product space layout, occupies a large space, and is not conducive to the structural stability and overall aesthetics of the rearview mirror. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a lightweight rearview mirror housing structure to solve the technical problems of the traditional automotive rearview mirror housing and bracket using a split design with screws and clips, which has cumbersome assembly process, reliance on assembly fixtures leading to increased costs and reduced production efficiency, and non-compact structural layout, large space occupation, and impact on stability and aesthetics.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A lightweight rearview mirror housing structure includes a housing, a connecting part and a support frame on the top of the housing, the connecting part being fixedly connected to the housing and the support frame respectively, the housing, the connecting part and the support frame being an integral injection molded structure, and a fixing groove being provided at one end of the support frame.

[0008] As an improved technical solution, the lower outer wall of the shell is provided with a folded edge, and the folded edge is fixedly connected to the shell. The inner side of the folded edge is connected to the shell through several reinforcing ribs.

[0009] As an improved technical solution, the outer wall of the support frame is provided with several hollowed-out grooves, and several reinforcing ribs are provided at the connection between the support frame and the connecting part.

[0011] As an improved technical solution, the buckle has an L-shaped structure, and the outer wall of the buckle is provided with a reinforcing three, one end of which is fixedly connected to the connecting part.

[0012] As an improved technical solution, the housing, connecting part and support frame assembly structure are all made of lightweight material ASA or ABS, and the bottom of the housing is provided with a mounting groove.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. The integrated design of this utility model achieves significant weight reduction while reducing the number of parts, making the space layout more compact; the support frame has a structural strength superior to the traditional split type through the reinforcement of the two ribs and the surface-to-surface treatment, which improves the overall stability.

[0029] like Figure 1 - Figure 5 As shown in the figure, this embodiment provides a lightweight rearview mirror housing structure, including a housing 1, a connecting part 2 and a support frame 3 on the top of the housing 1, the connecting part 2 being fixedly connected to the housing 1 and the support frame 3 respectively, the housing 1, the connecting part 2 and the support frame 3 being an integral injection molded structure, and a fixing groove 10 being provided at one end of the support frame 3; by integral injection molding, the production process is simplified, the cumbersome assembly process of the split design is eliminated, the production efficiency is improved, and the appearance defects caused by the connecting parts are avoided, enhancing the overall aesthetics.

[0030] In this example, the lower outer wall of the shell 1 is provided with a folded edge 4, and the folded edge 4 is fixedly connected to the shell 1. The inner side of the folded edge 4 is connected to the shell 1 by several reinforcing ribs 5. The cooperation between the folded edge 4 and the reinforcing ribs 5 improves the structural strength of the lower end of the shell 1, making the shell 1 more stable during use, while not adding too much weight, which is in line with the lightweight design concept.

[0031] In this example, the outer wall of the support frame 3 is provided with several hollow grooves 12, and several reinforcing ribs 6 are provided at the connection between the support frame 3 and the connecting part 2. The hollow grooves 12 reduce the weight of the support frame 3 and achieve lightweighting, while the reinforcing ribs 6 enhance the structural strength at the connection between the support frame 3 and the connecting part 2, making the overall structure more stable and the spatial layout more compact.

[0032] In this example, the top of the connecting part 2 has several through slots 7, and a buckle 8 is fixedly installed on one side of the through slot 7. The design of the through slot 7 reduces the weight of the connecting part 2, and the buckle 8 facilitates the later installation. No additional screws or other connecting parts are required, which simplifies the assembly process, improves production efficiency, and reduces costs.

[0033] In this example, the buckle 8 has an L-shaped structure, and the outer wall of the buckle 8 is provided with a reinforcing 3 9, one end of which is fixedly connected to the connecting part 2. The L-shaped buckle 8 has a simple structure and reliable connection. The reinforcing 3 9 further enhances the connection strength between the buckle 8 and the connecting part 2, ensuring that the buckle 8 is not easily damaged during use and improving the stability of the overall structure.

[0034] In this example, the combined structure of housing 1, connecting part 2 and support frame 3 is made of lightweight material ASA or ABS. The bottom of housing 1 is provided with mounting groove 11. The use of lightweight materials such as ASA or ABS reduces material costs and lightens the overall weight, which is in line with lightweight design. The mounting groove 11 facilitates the installation of other components, such as glass lenses, without adding extra assembly complexity, which is conducive to improving production efficiency.

[0035] In use, the shell 1 serves as the external protective structure. It forms a stable whole with the connecting part 2 and the support frame 3 through integrated injection molding. No additional connecting parts are required, which directly eliminates the assembly steps of separate parts. The integrated structure enables rapid production and installation.

[0036] The fixing groove 10 at one end of the support bracket 3 is used to connect with the relevant parts of the vehicle body. The hollow groove 12 on its outer wall reduces its own weight, while the side wall between adjacent hollow grooves 12 and the reinforcing rib 6 at the connection of the connecting part 2 together enhance the structural strength and ensure stable support.

[0037] The through groove 7 at the top of the connecting part 2 reduces weight, and the buckle 8 can directly engage with the corresponding structure of the vehicle body without screws. The reinforcement 9 on the outer wall of the buckle 8 ensures reliable connection and further simplifies assembly.

[0038] The folded edge 4 and reinforcing rib 5 at the lower end of the shell 1 enhance the strength of the shell 1. The mounting groove 11 at the bottom facilitates the integration of other components. The whole is made of lightweight ASA or ABS material, which reduces costs while ensuring strength and weather resistance.

[0039] Through the organic combination of various structural parts, the integrated shell 1, connecting part 2 and support frame 3 work together to achieve lightweight, high strength and easy assembly, meeting the usage requirements of automotive rearview mirrors.

[0040] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
