[0027] Understandably, the ingenious combination of the main support frame 100, the intermediate support frame 200, and the side support frames 300 forms a stable triangular support system, suitable for large-displacement three-wheeled motorcycles, and greatly improves the overall stability of the vehicle body. The connection method between the components is reasonably designed, simplifying the installation process, reducing installation difficulty, improving assembly efficiency, and achieving multiple advantages such as structural stability, convenient installation, strong adaptability, and lightweight design.

[0028] Reference Figure 2Specifically, a first support rod 211 is added to the bottom rear end of each tube assembly 210. These first support rods 211 are connected to the main support bracket 100, providing additional support to the intermediate support bracket 200 and enhancing the structural stability. Simultaneously, the support plate 230 is cleverly designed between the first support rod 211 and the fixed tube, forming a stable support area for installing and supporting the vehicle's seat cushion. To further enhance the structural strength and stability, reinforcing rods 212 are installed in the middle of the first support rod 211. These reinforcing rods 212 are inclined towards the mounting plate and connected to the tube assembly 210, forming a triangular structure together with the first support rod 211 and the tube assembly 210. This triangular structure design not only improves the overall load-bearing capacity but also effectively disperses stress, making the entire mounting frame more stable and durable, better able to cope with various complex road conditions and driving conditions.

[0029] Furthermore, a second support rod 213 is added to the rear end of each tube group 210. These second support rods 213 are also used to connect the main support bracket 100, and together with the first support rod 211, they provide more comprehensive support for the intermediate support bracket 200, improve the stability of the structure, and enable the mounting bracket to better adapt to seat cushions of different sizes and weights, thereby improving the comfort and riding experience of the vehicle. They also further enhance the support capacity of the intermediate support bracket 200, enabling the mounting bracket to more stably support the seat cushion and other vehicle body components.

[0030] Furthermore, a positioning protrusion 240 is added between the two tube assemblies 210. The positioning protrusion 240 is located between the first support rod 211 and the second support rod 213, and its top extends out of the top of the tube assembly 210. It is used to support and position the installation of the seat cushion, which not only makes the installation of the seat cushion more convenient and quick, but also improves the stability and comfort of the seat cushion, providing a stable and reliable installation platform for the seat cushion.

[0031] In some embodiments, wing plates 231 are added to both sides of the support plate 230. The wing plates 231 are perpendicular to the support plate 230 and located at its bottom, forming a triangular design. The two wing plates 231 and the support plate 230 together form a slot for quick positioning and snapping between the two pipe assemblies 210, which not only simplifies the installation process of the support plate 230, making the installation of the support plate 230 more convenient and faster, but also improves its stability and load-bearing capacity.

[0032] Reference Figure 2 Specifically, a second mounting plate 312 is added to the tail end of the mounting section in the side bracket 300. This second mounting plate 312 is connected to the two main beam pipes 310 and, together with the first mounting plate 311 and the main beam pipes 310, supports the mudguard. This design not only improves the stability and load-bearing capacity of the mudguard but also makes the installation of the mudguard more convenient and quick.

[0033] Furthermore, a second connecting pipe 330 is added to the main beam pipe 310 facing the main support 100. These second connecting pipes 330 are located on the side of the mounting position and include two horizontally arranged transverse pipes 331 and a longitudinal pipe connecting the two transverse pipes 331. The transverse pipes 331 are inclined downwards towards the tail end of the main beam pipe 310, allowing the connection to better connect with the main support 100 and improving the stability of the connection.

[0034] Furthermore, the second connecting pipe 330 extends from the upper transverse pipe 331 towards the side away from the mounting position to form a connecting portion for connecting the main support 100. Simultaneously, reinforcing pipes 333 are added at the connection between the connecting portion and the longitudinal pipe. These reinforcing pipes 333 are angled to the longitudinal pipe, and their ends are connected to the main support 100. This further enhances the connection strength between the second connecting pipe 330 and the main support 100, improving the overall stability of the mounting frame.

[0035] Reference Figure 1 It should be noted that the main support 100 includes a handle mounting bracket 110, a fuel tank mounting bracket 120, and a seat mounting bracket 130 connected sequentially from front to back. The intermediate support 200 is connected to the seat mounting bracket 130. The structure of the entire mounting bracket is more compact and reasonable, and facilitates the installation and disassembly of each component.

[0036] The second aspect of this utility model also proposes a three-wheeled motorcycle, particularly a large-displacement three-wheeled motorcycle, including a chassis mounting frame as described in any of the preceding claims. By employing the aforementioned chassis mounting frame, this three-wheeled motorcycle not only improves the overall performance and stability of the vehicle but also allows the various components of the vehicle to fit together more tightly, thereby improving the overall performance and service life of the vehicle.
