[0026] Reference Figure 1 and Figure 2This utility model proposes an intermediate support, comprising two sets of tubes 100 arranged symmetrically to each other. Each set of tubes 100 includes a front end 101 and a rear end 102. The front end 101 is provided with a connecting hole 101a for connecting to the front of the vehicle body, and the rear end 102 is used to install the seat cushion of the vehicle body. A fixing tube 200 is connected to the end of the rear end 102, and the fixing tube 200 is connected to both sets of tubes 100. The rear end 102 is provided with an ear plate 300, which is arranged horizontally and used to fix the seat cushion. An installation space is provided between the two sets of tubes 100. The mounting plate 400 is used to support the tail box of the vehicle body. The mounting plate 400 is arranged adjacent to the fixing tube 200. A first support rod 110 is provided at the bottom of the rear end 102. The first support rod 110 is connected to the base of the vehicle body. The mounting plate 400 is located between the first support rod 110 and the fixing tube 200. A reinforcing rod 130 is provided in the middle of the first support rod 110. The reinforcing rod 130 is inclined towards the mounting plate 400 and is connected to the tube assembly 100. The reinforcing rod 130, the first support rod 110, and the tube assembly 100 form a triangular structure.

[0027] In a specific embodiment, each tube assembly 100 consists of a front end 101 and a rear end 102. The front end 101 is designed with a connection hole 101a for secure connection to the front of the motorcycle body. The rear end 102 is used to install the motorcycle seat, and a fixing tube 200 is connected to the end of the rear end 102. The fixing tube 200 spans the two tube assemblies 100, realizing the interconnection and reinforcement of the two tube assemblies 100. Horizontally arranged ear plates 300 are provided at appropriate positions on the rear end 102. These ear plates 300 are used to fix the seat and ensure that the seat is stable and does not wobble. Between the two tube assemblies 100, a mounting plate 400 is provided to support and install the motorcycle's tail box. Its position is close to the fixing tube 200, which facilitates the quick installation and removal of the tail box. At the bottom of the rear end 102, a first support rod 110 is provided. The first support rod 110 is connected to the motorcycle's base, providing additional support for the entire intermediate support. A reinforcing rod 130 is also provided in the middle of the first support rod 110. The reinforcing rod 130 is inclined towards the mounting plate 400 and connected to the pipe assembly 100 to form a triangular structure. The triangular structure greatly enhances the stability and load-bearing capacity of the bracket and effectively prevents deformation or damage under complex road conditions.

[0028] Understandably, the symmetrical arrangement of two sets of pipe assemblies 100, fixing pipe 200, ear plate 300, mounting plate 400, and the cooperation of the first support rod 110 and reinforcing rod 130 forms a stable yet flexible support system, effectively improving the overall stability of the motorcycle. The rational design of each component, along with the connection hole 101a and ear plate 300, simplifies and speeds up the installation process, reducing installation difficulty and cost. In particular, the triangular structure formed by the reinforcing rod 130, the first support rod 110, and the pipe assembly 100 greatly enhances the load-bearing capacity of the bracket, ensuring safe operation of the motorcycle under heavy loads or harsh road conditions. Especially noteworthy is that the intermediate bracket proposed in this invention is suitable for use in large-displacement three-wheeled motorcycles, meeting the structural strength and usage requirements of such vehicles.

[0029] Reference Figure 1 Furthermore, the tube assembly 100 is equipped with a second support rod 120, which is also used to connect to the base of the vehicle body, complementing the first support rod 110 and providing additional stability and support for the intermediate support. This dual support rod structure is particularly suitable for high-performance motorcycles, including large-displacement three-wheeled motorcycles, to ensure vehicle stability at high speeds or in harsh road conditions.

[0030] Furthermore, the rear end 102 of the tube assembly 100 is also provided with a positioning protrusion 500, which is located between the first support rod 110 and the second support rod 120. Its top extends out of the top of the tube assembly 100, providing more precise positioning and support for the installation of the seat, which not only enhances the stability of the seat but also optimizes the rider's riding experience.

[0031] Reference Figure 1 and Figure 2 It should be noted that at least four ear plates 300 are provided, two of which are respectively arranged adjacent to two second support rods 120 to strengthen the connection between the support rods and the vehicle body; the other two are arranged on the connecting rod and are symmetrically arranged along the symmetry line of the two tube groups 100. This layout further enhances the overall stability of the intermediate support.

[0032] Reference Figure 1 It should be noted that the mounting plate 400 is connected to two wing plates 410 on both sides. The wing plates 410 are perpendicular to the mounting plate 400 and located at the bottom of the mounting plate 400, forming a triangular structure. The two wing plates 410, together with the mounting plate 400, form a slot for quick positioning and snapping between the two pipe assemblies 100, simplifying the installation process and improving installation efficiency.

[0033] Reference Figure 1 and Figure 2It should be noted that a transition section 103 is provided between the front end 101 and the rear end 102. The transition section 103 is inclined, connecting the front end 101 at a lower position and the rear end 102 at a higher position. This design not only conforms to ergonomics but also allows the intermediate support to better adapt to the streamlined body structure, improving the overall aesthetics of the vehicle. In particular, the front end 101, the transition section 103, and the rear end 102 are integrally formed and connected to form a structurally stable tube assembly 100, further improving the strength of the support and simplifying the assembly steps of the motorcycle body.

[0034] It should be noted that both transition sections 103 are inclined outwards away from the opposite tube assembly 100, while the two front ends 101 are inclined inwards towards the opposite tube assembly 100. This not only enhances the structural strength of the intermediate support but also makes it fit the streamlined vehicle body structure better, reducing wind resistance during driving.

[0035] Reference Figure 1 In a specific embodiment, each of the two sets of pipe assemblies 100 is provided with at least two fixing slots 420. These fixing slots 420 are evenly distributed along the four corners of the mounting plate 400 for fixing the tail box. This not only improves the installation stability and convenience of the tail box, but also enhances the overall coordination between the tail box and the vehicle body.

[0036] Furthermore, referring to Figure 1 and Figure 2 One or more connecting pipes are added between the two pipe groups 100. These connecting pipes span the front end 101, middle, or rear end 102 of the two pipe groups 100, forming an additional reinforcement structure. The two ends of the connecting pipes are connected to corresponding positions in the two pipe groups 100, and the connection method can be welding, bolting, or other reliable connection methods. The number, position, and length of the connecting pipes can be determined according to actual needs to achieve the best reinforcement effect.

[0037] In other embodiments, a triangular reinforcement structure is provided between the two pipe groups 100. Specifically, one or more connecting pipes can be provided between the front end 101, middle, or rear end 102 of the two pipe groups 100, and then a support rod is provided between the connecting pipe and the pipe group 100, with one end of the support rod connected to the connecting pipe and the other end connected to a corresponding position in the pipe group 100. In this way, multiple triangular structures are formed between the connecting pipe, the support rod, and the pipe group 100. Triangular structures are well-known stable structures that can effectively resist loads and deformations in various directions. Therefore, by providing a triangular reinforcement structure, the stability and load-bearing capacity of the intermediate support can be further enhanced.

[0038] The second aspect of this utility model also proposes a vehicle body mounting bracket, including any of the intermediate brackets described above. This vehicle body mounting bracket not only has all the advantages of the aforementioned intermediate brackets, but can also be adapted to specific vehicle models to meet the installation requirements of different vehicle models.

[0039] The third aspect of this utility model also proposes a three-wheeled motorcycle, including the aforementioned chassis mounting frame. Through the optimized chassis mounting frame, especially for large-displacement three-wheeled motorcycles, the overall stability and safety of the three-wheeled motorcycle are significantly improved, while riding comfort and aesthetics are also optimized. This three-wheeled motorcycle is suitable for various road conditions and transportation needs, and has broad application prospects.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
