Description

Technical Field

[0001] This utility model belongs to the field of motorcycle assembly technology, specifically relating to a hidden pre-installed structure for a two-wheeled motorcycle seat. Background Technology

[0002] Motorcycle seats support the weight of riders and passengers, mitigating and damping impacts and vibrations transmitted from the vehicle body, creating a smooth and comfortable riding experience. In traditional straight-beam two-wheeled motorcycle seat installation designs, two common methods exist: One is a split installation: the seat assembly (including foam and cover) is directly bolted to the seat support beam of the frame through mounting holes in its bottom metal base plate. This method is simple in structure but inefficient, and the metal base plate is directly exposed, affecting the overall aesthetics of the vehicle. Furthermore, the base plate is susceptible to rust from rain and dust. The other is a bracket installation: a separate metal bracket (usually a stamped steel plate) is first fixed to the frame, and then the seat assembly is installed onto this bracket. While this method improves the convenience of seat disassembly and maintenance to some extent, it often still results in parts of the seat base plate or bracket structure being exposed, failing to fundamentally improve aesthetics. Moreover, the step-by-step installation of multiple parts reduces production assembly efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a concealed pre-installed structure for a two-wheeled motorcycle seat, so as to solve the problems of insufficient aesthetics after installation, cumbersome assembly process, and easy corrosion of parts in the aforementioned background technology.

[0004] The objective of this utility model can be achieved using the following technical solutions: A concealed pre-assembled seat structure for a two-wheeled motorcycle includes a seat assembly, a bracket, and a frame assembly. The bracket is located at the rear end of the frame assembly, and the seat assembly is mounted on the bracket. The seat assembly includes a seat base plate. A filling layer is provided on the seat base plate. A skin is covered on the filling layer. The seat base plate of the seat assembly is pre-connected to the upper part of the bracket by fastening bolts to form a pre-assembled module. The pre-assembled module is connected to the straight beam tube of the frame assembly through a connecting structure provided at the lower part of the bracket.

[0005] The upper part of the bracket is provided with an upper mounting surface that matches the shape of the seat base plate, and the upper mounting surface is also provided with a pre-embedded nut for connecting with the seat base plate.

[0006] The lower part of the bracket is provided with a connecting lug, and the straight beam tube of the frame assembly is provided with a mounting connecting plate that cooperates with the connecting lug.

[0007] A cushioning block is provided between the seat base plate and the upper mounting surface of the bracket.

[0008] The seat assembly completely covers the bracket and conceals the seat base.

[0009] The filling layer is a sponge.

[0010] The bracket is an aluminum alloy bracket, and is machined from die-cast aluminum alloy profiles.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model has a novel structure and a reasonable layout. Through this structure, the seat cushion and a specially designed aluminum alloy bracket are pre-assembled into a complete modular unit outside the production line, and then assembled onto the vehicle frame. This achieves complete concealment of the seat cushion bottom plate, improves the overall aesthetics of the vehicle, increases assembly efficiency, and enhances corrosion resistance.

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1-3As shown, a concealed pre-assembled seat structure for a two-wheeled motorcycle includes a seat assembly 1, a bracket 2, and a frame assembly 3. The bracket 2 is located at the rear end of the frame assembly 3, and the seat assembly 1 is mounted on the bracket 2. The seat assembly 1 includes a seat base plate 11. A filling layer 12 is provided on the seat base plate 11. The filling layer 12 is filled with sponge. A skin 13 covers the filling layer 12. The seat base plate 11 of the seat assembly 1 is pre-connected to the upper part of the bracket 2 by fastening bolts to form a pre-assembled module. The pre-assembled module is connected to the straight beam tube 31 of the frame assembly 3 through a connecting structure at the lower part of the bracket 2. The pre-assembled module separates the assembly process of the seat assembly 1 and the bracket 2 from the main assembly line, pre-assembling them as sub-modules, simplifying the main assembly process, improving production cycle and efficiency. This modular design facilitates production and inventory management, and also facilitates after-sales maintenance and replacement. The entire seat module can be replaced simply by loosening the connection point with the frame.

[0019] The upper part of the bracket 2 is provided with an upper mounting surface 21 that matches the shape of the seat base plate 11; the upper mounting surface 21 is also provided with a pre-embedded nut 22 for connecting with the seat base plate 11; the lower part of the bracket 2 is provided with a connecting lug 25, and the straight beam tube 31 of the frame assembly 3 is provided with a mounting connecting plate 32 that cooperates with the connecting lug 25; a buffer rubber block 24 is provided between the seat base plate 11 and the upper mounting surface 21 of the bracket 2. The buffer rubber block 24 is a mushroom-shaped rubber block, which is stuck between the seat base plate 11 and the upper mounting surface 21 of the bracket 2 to play a shock absorption role.

[0020] The seat assembly 1 completely covers the bracket 2 and hides the seat base plate 11. After the seat assembly 1 is installed, the structure of the seat base plate 11 and the bracket 2 is completely hidden, resulting in a clean and smooth rear profile that significantly enhances the product's premium feel and aesthetics. The bracket 2 is an aluminum alloy bracket, machined from die-cast aluminum alloy profiles. Using aluminum alloy to manufacture the bracket 2 ensures structural strength and rigidity while achieving a lighter structure compared to traditional steel brackets.

[0021] In use, the seat base plate 11 of the seat assembly 1 is first connected to the bracket 2 by fastening bolts 4 to form a pre-assembled module. Then, the pre-assembled module is transported to the top of the frame assembly 3, so that the connecting structure at the bottom of the bracket 2 is aligned with the mounting connecting plate 32 on the straight beam tube 31 of the frame 2 and connected and fixed. After the seat assembly 1 is installed, the structure of its seat base plate 11 and bracket 2 is completely hidden, the rear of the vehicle has a clean and smooth line, which significantly improves the product's premium feel and aesthetics, as well as improves assembly efficiency and corrosion resistance.

[0022] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
