[0022] Refer to Figures 1 to 5 , this application proposes a frame, specifically, a motorcycle frame with novel design, stable structure and convenient for installing various accessories. The following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings to better understand the technical solution of the present invention and the technical effects brought by it.

[0023] The overall structure of the frame mainly includes a left frame 100, an intermediate connector 200 and a right frame 300. The left frame 100 and the right frame 300 are the main parts of the frame, and their structures are similar, both using die-castings with thin-wall structures. Designing as die-castings with thin walls not only reduces the overall weight of the frame, but also ensures the strength and rigidity of the frame, enabling the frame to withstand various loads generated during the driving of the motorcycle.

[0024] The left frame 100 and the right frame 300 are arranged oppositely to form the basic framework of the frame. A space is formed between the left frame 100 and the right frame 300 to arrange components such as a fuel tank 400 and a storage box 500.

[0025] To support and fix the left frame 100 and the right frame 300, the intermediate connector 200 is arranged between the left frame 100 and the right frame 300, playing a role of connection and fixation. The intermediate connector 200 is fixed to the left frame 100 and the right frame 300 through fasteners (such as bolts, nuts, etc.), making each part of the frame tightly connected together to form a whole. This connection method is not only simple and reliable, but also convenient for disassembly and maintenance.

[0026] In a specific implementation, the intermediate connector 200 can be designed in various shapes, sizes and quantities to adapt to different models and specifications of motorcycles. At the same time, the material of the intermediate connector 200 can also be selected according to needs to ensure its strength and durability.

[0027] At the front ends of the left frame 100 and the right frame 300, a head tube 310 is provided. The head tube 310 is the installation structure for the front handle and front fork of the motorcycle and is a key component of the motorcycle steering system. In a specific implementation, the head tube 310 can be integrally formed with the left frame 100 or the right frame 300 to improve the overall strength and rigidity of the frame.

[0028] On both the left frame 100 and the right frame 300, a number of accessory mounting parts 110 are integrally formed. The accessory mounting parts 110 are used to mount motorcycle accessories such as the front footrest, rear footrest, rear armrest, fuel tank 400, battery box, and electronic controller. Through the accessory mounting parts 110, the above-mentioned accessories can be quickly mounted on the frame, improving the production efficiency of the motorcycle.

[0029] In a specific implementation, the accessory mounting parts 110 can be designed into various shapes and sizes according to the specific needs of the motorcycle to adapt to different models and specifications of accessories. At the same time, connection structures such as threaded holes and card slots can also be provided on the accessory mounting parts 110 to facilitate the installation of various accessories.

[0030] The frame proposed in this application, which is applied to a motorcycle, has the following technical effects: 1. Reduce weight and improve performance. The left frame 100 and the right frame 300 are made of die-castings with a thin-wall structure, which have the advantages of light weight and high structural strength. This design not only reduces the weight of the frame but also helps to reduce the overall weight of the motorcycle, thereby improving the acceleration performance and fuel economy of the motorcycle.

[0031] 2. Simplify the production process and improve efficiency. A number of accessory mounting parts 110 are integrally formed on the left frame 100 and the right frame 300, reducing the number of parts and simplifying the production process. This not only reduces the production cost but also improves the production efficiency, making the production of the frame faster and more efficient.

[0032] 3. Improve the stability and durability of the frame. The intermediate connecting piece 200 tightly connects the left frame 100 and the right frame 300 together through fasteners, forming a whole, making the structure of the frame stable and improving the stability and durability of the frame. At the same time, the thin-wall structure of the left frame 100 and the right frame 300 also enhances the torsional strength and impact resistance of the frame, enabling the frame to better withstand various loads generated during the driving of the motorcycle.

[0033] 4. Facilitate the installation and disassembly of accessories. The design of the accessory mounting parts 110 enables the accessories to be firmly mounted on the frame during the assembly operation of the motorcycle and is also convenient for disassembly and replacement. This design not only improves the expandability and flexibility of the motorcycle but also facilitates the use and maintenance of the user.

[0034] The frame of this application fully considers the overall performance of the motorcycle and the needs of users in design. Through reasonable structural design and material selection, the frame achieves light weight, high strength, and easy maintenance. It not only improves the performance and service life of the motorcycle, but also reduces the production cost and maintenance cost, enhancing the product competitiveness.

[0035] Referring to Figure 1 and Figure 2 , in some embodiments of this application, the accessory mounting part 110 includes a front footrest bracket, a rear footrest bracket, a rear armrest bracket, a fuel tank mounting interface, a battery box mounting interface, and so on. The front footrest bracket and the rear footrest bracket are respectively arranged on the outer sides of the left side frame 100 and the right side frame 300, facilitating the passengers to get on and off the vehicle and the footrest requirements during riding. The rear armrest bracket is arranged at the rear ends of the left side frame 100 and the right side frame 300, providing stable support for the passengers and facilitating the installation of a tail box. The fuel tank mounting interface and the battery box mounting interface are arranged between the left side frame 100 and the right side frame 300, facilitating the installation and removal of the fuel tank 400 and the battery box, and at the same time keeping the frame clean and beautiful. The battery box mounting interface is arranged on the middle bracket, and the middle bracket can also be used to mount components such as an electronic controller, which can be determined according to the actual structure and requirements of the motorcycle and will not be elaborated here one by one.

[0036] Referring to Figure 4 , in some embodiments of this application, the left side frame 100 includes a front inclined plate 101, a bottom horizontal plate 102, and a rear inclined plate 103 that are connected in sequence. The bottom horizontal plate 102 is connected to the lower ends of the front inclined plate 101 and the rear inclined plate 103, forming the bottom support of the frame. An X-shaped support plate 104 is arranged between the front inclined plate 101 and the rear inclined plate 103, which not only enhances the strength and stability of the frame, but also makes the frame more visually hierarchical. The X-shaped support plate 104 forms multiple hollow parts, which is beneficial to reducing the weight of the frame on the premise of meeting the structural strength requirements. Among them, the main structure of the right side frame 300 is basically the same as that of the left side frame 100, ensuring the symmetry and balance of the frame.

[0037] In order to further improve the performance of the frame, the thickness of the materials of the frame components is also optimized. Specifically, the front inclined plate 101, the bottom horizontal plate 102, the rear inclined plate 103, and the support plate 104 are set with non-uniform wall thicknesses. This design can adjust the wall thickness according to the stress conditions and functional requirements of each part, and optimize it for different models of motorcycles, so that the frame can reduce weight as much as possible while meeting the strength and stiffness requirements, improving the fuel economy and handling performance of the vehicle.

[0038] Referring to Figure 4, in addition, in order to improve the stiffness and torsional resistance of the frame, the present invention also provides a plurality of reinforcing ribs 105 on the opposite surfaces of the left frame 100 and the right frame 300. The left frame 100 and the right frame 300 are thin-walled structures, and side plates are provided at the edges. The reinforcing ribs 105 have various directions and can be arranged in various ways such as parallel, intersecting, and end-to-end connected. Moreover, the ends of the reinforcing ribs 105 are connected to the side plates to form a complex reinforcing structure. The thicknesses of the plurality of reinforcing ribs 105 are also non-uniformly arranged and can be optimized according to the force conditions of the frame. The arrangement of the reinforcing ribs 105 can significantly improve the strength and stability of the frame, enabling the vehicle to maintain a stable posture under various road conditions.

[0039] It should be understood that the non-uniform arrangement of the thicknesses of the plurality of reinforcing ribs 105 means that the thicknesses of the plurality of reinforcing ribs 105 are not the same. It can be that the thicknesses of some of the reinforcing ribs 105 are larger and the thicknesses of some of the reinforcing ribs 105 are smaller. For example, the thickness of the reinforcing rib 105 provided on the support plate 104 is larger; it can also be that the thickness of each reinforcing rib 105 changes, rather than just having a uniform thickness. For example, the thickness gradually decreases from the position with greater force to the position with smaller force.

[0040] Moreover, as Figure 4 shown, in order to facilitate the connection of electricity to the components of the motorcycle and the arrangement and management of electric wires, wire grooves are also provided on the opposite surfaces of the left frame 100 and the right frame 300. The wire grooves can be used to accommodate the electric wires, avoiding the exposure of the electric wires outside, and improving the cleanliness and safety of the frame. At the same time, the design of the wire grooves can also be optimized according to the number and routing of the electric wires, enabling the electric wires to be neatly arranged inside the frame, facilitating subsequent maintenance and repair.

[0041] Referring to Figure 1 and Figure 2, in some embodiments of the present application, a fuel tank accommodation cavity 106 and an article storage box accommodation cavity 107 are formed between the left frame 100 and the right frame 300 of the vehicle frame. The fuel tank accommodation cavity 106 is located in front of the article storage box accommodation cavity 107, and this layout fully considers the usage requirements and space utilization rate of the fuel tank 400 and the article storage box 500. The fuel tank 400 is arranged at the front of the motorcycle, so that the space of the article storage box accommodation cavity 107 is larger, while the article storage box 500 is located at the rear, which is convenient for passengers to store items. The fuel tank 400 is installed in front of the vehicle frame, and the left frame 100 and the right frame 300 of the vehicle frame are in a "hugging shape". On the basis of ensuring strength, it can better protect the fuel tank 400 and at the same time increase the capacity of the fuel tank 400. In addition, the fuel tank 400 adopts a sunken layout and is arranged in front of the vehicle frame, which can well move some electrical components forward, increasing the longitudinal space of the article storage box 500; the rear end of the vehicle frame is in an outward-expanded shape, increasing the lateral space of the article storage box 500; the tail of the article storage box 500 integrates the height of the rear armrest bracket, increasing the vertical space of the article storage box 500, so that the article storage box 500 can hold two helmets 600, optimizing the space utilization of the motorcycle, solving the problem of difficult placement of two helmets 600 in the past, and improving the practicality of the motorcycle.

[0042] X-shaped support plates 104 are distributed on both sides of the fuel tank accommodation cavity 106. The support plates 104 not only play a role in forming the fuel tank accommodation cavity 106, but also enhance the overall structural strength of the vehicle frame, which is beneficial to protecting the fuel tank 400. By reasonably designing the shape and position of the support plates 104, the stability and safety of the fuel tank 400 during driving can be ensured.

[0043] Referring to Figure 3 , in some embodiments of the present application, the intermediate connecting member 200 includes a plurality of connecting rods. The plurality of connecting rods are arranged on the outer periphery of the fuel tank accommodation cavity 106. On the one hand, the plurality of connecting rods effectively connect the left frame 100 and the right frame 300, enhancing the overall rigidity and stability of the vehicle frame. The arrangement of the plurality of connecting rods also improves the torsional resistance of the vehicle frame, enabling the motorcycle to better resist the influence of external torque during driving. On the other hand, the plurality of connecting rods can also help fix and protect the fuel tank 400. The fuel tank 400 is usually assembled by two half-shells, and side plates are formed at the joint surface of the two half-shells for easy installation. The side plates can be fixed to the connecting rods and / or the left frame 100 and the right frame 300, thereby fixing the fuel tank 400.

[0044] The number and position of the connecting rods can be optimized according to the specific dimensions and load requirements of the vehicle frame. By increasing the number of connecting rods or adjusting their positions, the structural strength and stability of the vehicle frame can be further improved. The shape of the connecting rods can be cylindrical, prismatic or other specially designed shapes, depending on the specific model of the motorcycle.

[0045] Referring toFigure 3 and Figure 5 In some embodiments of the present application, a cradle 210 is connected to the workshop, and the cradle 210 is used to mount an engine. Wherein, shaft holes 211 are provided on both the left and right sides of the cradle 210, and fastening bolts 212 are provided in the shaft holes 211. The fastening bolts 212 are fixed to the left side frame 100 or the right side frame 300, and buffer rubber sleeves 213 are sleeved on the fastening bolts 212 to absorb lateral vibrations; a front support arm 214 is provided at the front end of the cradle 210, and a U-shaped opening is provided at the end of the front support arm 214. A hollow buffer block 215 with a free stroke is provided in the U-shaped opening. The vehicle frame is provided with a limiting groove 108, and the hollow buffer block 215 is located in the limiting groove 108. Two opposite side walls of the limiting groove 108 define the hollow buffer block 215 to absorb longitudinal vibrations. Therefore, the vibration generated during the operation of the engine can be greatly reduced from being transmitted to the vehicle frame, improving the comfort and stability of riding. Among them, the buffer rubber sleeves 213 and the hollow buffer blocks 215 are usually made of elastic rubber or silica gel materials. Two U-shaped plates can be integrally formed on the vehicle frame, and a limiting groove 108 is formed between the two U-shaped plates. The two U-shaped plates are the two opposite side walls of the limiting groove 108, and the hollow buffer block 215 is defined by the two U-shaped plates, with a solid and durable structure and high reliability.

[0046] Referring to Figure 3 In some embodiments of the present application, the head tube 310 is integrally formed at the front end of the right side frame 300. This design simplifies the connection structure between the head tube 310 and the right side frame 300, improves the connection stability and reliability, reduces the assembly steps, and compared with the traditional welding fixation method, greatly improves the shape and dimensional accuracy of the head tube 310, preventing the head tube 310 from being scrapped due to position deviation during welding.

[0047] At the same time, a shield 120 is provided at the front end of the left side frame 100. The shield 120 covers the left side of the head tube 310 and is fixed to the head tube 310. The design of the shield 120 not only plays a role in fixing and protecting the head tube 310, but also improves the structural strength and stiffness of the whole vehicle. Usually, a plurality of reinforcing ribs, such as grid-shaped reinforcing ribs, are provided on the outer surface of the shield 120 to enhance the structural strength. The shield 120 and the head tube 310 can be fixed by fasteners such as bolts, which is convenient for disassembly, installation and maintenance.

[0048] By designing the head tube 310 to be integrally formed with the right side frame 300, the number of components and the assembly steps are reduced, and the production cost and assembly difficulty are lowered. The design of the shield 120 further enhances the protection effect of the head tube 310, preventing it from being collided and damaged by external objects during driving.

[0049] Embodiments of the second aspect of the present application provide a motorcycle. The motorcycle adopts the frame of the embodiments of the first aspect, including all the technical solutions of the frame, and has all the technical solutions of the frame, which will not be elaborated one by one.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
