Description

Technical Field

[0001] This utility model relates to a motorcycle structure, and more particularly to an off-road motorcycle frame adapted to different shock absorption structures. Background Technology

[0002] As a mode of transportation specifically designed for complex terrain, the suspension system of a motocross motorcycle plays a crucial role in the riding experience. The suspension system primarily works through the combination of the rear fork (rear suspension) and the shock absorber to absorb and filter terrain impacts, ensuring vehicle stability and rider comfort. In practical applications, the rear fork needs to sway with changes in terrain, and the suspension structure effectively buffers vibrations and impacts. Depending on the terrain intensity and riding requirements, there are various types of suspension structures, the most representative of which include direct-mount shock absorbers and rocker-mount shock absorbers.

[0003] Direct-mount shock absorbers have a simple structure, directly connecting the shock absorber between the frame and the rear fork, providing a linear or near-linear damping response. This design offers direct response, low manufacturing cost, and light weight, making it suitable for flat roads or low-intensity off-road scenarios, such as recreational riding or entry-level off-roading. However, when facing high-intensity terrain such as large drops or continuous bumps, its damping travel and damping adjustment range are limited, which can easily lead to insufficient damping, bottoming out, or unstable handling.

[0004] In contrast, the rocker-mounted suspension (or linkage suspension) indirectly connects the shock absorber and the rear fork through a rocker arm linkage mechanism, achieving progressive damping characteristics. This structure can gradually increase the damping force according to the compression stroke, providing a smooth and comfortable ride during small bumps and strong support during large impacts, effectively absorbing extreme impact forces. It is suitable for professional racing or high-intensity off-road environments. Although it has excellent performance, its structure is complex, has many parts, and has higher maintenance costs.

[0005] In existing technologies, off-road motorcycle frame designs typically only accommodate a single shock absorber structure. For example, some frames only have direct mount positions and are incompatible with swayback linkage systems; and vice versa. This prevents users from flexibly adjusting the shock absorber structure when faced with different terrains or changing riding needs, requiring the replacement of the entire frame, increasing cost and inconvenience. Furthermore, the lack of compatibility in existing frames limits the motorcycle's adaptability to various scenarios and fails to meet personalized or upgrade requirements.

[0006] Therefore, existing off-road motorcycle frames suffer from poor compatibility of shock absorption structures and inconvenient adjustments. There is an urgent need for a frame design that can adapt to various shock absorption structures in order to improve the versatility and practicality of the vehicle. Utility Model Content

[0007] This utility model discloses an off-road motorcycle frame adapted to different shock absorption structures, including a frame, a rear fork, and a shock absorber. The rear fork rotation shaft connection of the frame is rotatably connected to the rear fork rotation shaft. The frame is provided with a shock absorber mounting block, which has a direct mounting position and a rocker arm mounting position. The frame is provided with a rocker arm connecting rod connection position, which is used to connect the shock absorber rocker arm connecting rod.

[0008] This utility model provides a technical solution for off-road motorcycle frames that can adapt to both direct-mount and rocker-mount shock absorber structures by setting shock absorber mounting blocks, rocker mount mounting positions, and rocker mount connecting positions on the frame. This solves the problem that existing frames only support a single shock absorber structure and it is difficult to adjust or replace the shock absorber structure without changing the frame.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A cross-country motorcycle frame adaptable to different shock absorption structures includes a frame, a rear fork, and a shock absorber. The rear fork rotation shaft connection of the frame is rotatably connected to the rear fork rotation shaft. The frame is provided with a shock absorber mounting block, which has a direct mounting position and a rocker arm mounting position. The frame is provided with a rocker arm linkage connection position, which is used to connect the shock absorber rocker arm linkage.

[0010] Further configuration involves connecting the shock absorber's frame connection end to the shock absorber connection bracket's connecting ear, and connecting the shock absorber connection bracket's connecting hole to the direct mount position.

[0011] Further, the rear fork connection end of the shock absorber is connected to the shock absorber connection position of the rear fork.

[0012] Further configuration involves connecting the shock absorber's frame connection end to the shock absorber connection bracket's connecting ear, and connecting the shock absorber connection bracket's connecting hole to the cradle mounting position.

[0013] Further configuration: The shock-absorbing rocker arm linkage includes: a connecting rod and a rocker arm. One end of the connecting rod is connected to the rocker arm connecting rod connection position, the other end of the connecting rod is connected to one end of the rocker arm, the other end of the rocker arm is connected to the rear fork connection end of the shock absorber, and the middle position of the rocker arm is connected to the shock absorber connection position of the rear fork.

[0014] This utility model provides a technical solution for off-road motorcycle frames that can adapt to both direct-mount and rocker-mount shock absorber structures by setting shock absorber mounting blocks, rocker mount mounting positions, and rocker mount connecting positions on the frame. This solves the problem that existing frames only support a single shock absorber structure and it is difficult to adjust or replace the shock absorber structure without changing the frame.

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, this utility model provides a cross-country motorcycle frame adaptable to different shock absorption structures, including a frame 1, a rear fork 2, and a shock absorber 5. The rear fork rotation shaft connection 11 of the frame 1 and the rear fork rotation shaft 21 of the rear fork 2 are rotatably connected via a pin, bolt, or other rotating connector, allowing the rear fork 2 to swing relative to the frame 1 to adapt to terrain changes and absorb impacts.

[0021] The frame 1 is equipped with a shock absorber mounting block 3, which is integrally formed at the rear of the frame 1 or fixedly connected by welding, bolts, or other methods. The shock absorber mounting block 3 has a direct mounting position 31 and a rocker arm mounting position 32. These mounting positions can be structures such as screw holes, pin holes, or slots, used for different mounting methods of the shock absorber 5. In addition, the frame 1 is also equipped with a rocker arm connecting position 12, which can be a pin hole or a shaft seat, used to connect the shock absorber rocker arm connecting rod 6, thereby achieving compatibility of the rocker arm type shock absorber structure.

[0022] The shock absorber 5 includes a frame connection end 51 and a rear fork connection end 52. These connection ends can be lugs, ball joints, or threaded interfaces for connection to corresponding components. The shock absorber connection bracket 4, as an adapter, includes a connection lug 41 and a connection hole 42. The connection lug 41 is used to connect to the frame connection end 51 of the shock absorber 5 via a pin or bolt, and the connection hole 42 is used to mate with the mounting position on the shock absorber mounting block 3.

[0023] This utility model allows for flexible switching of the shock absorption structure according to usage requirements. The specific implementation methods are divided into two modes: direct mounting of the shock absorber and shock absorption cradle.

[0024] Direct-mount implementation of shock absorbers: such as Figure 1 and Figure 2 As shown, in this mode, the frame connection end 51 of the shock absorber 5 is connected to the connecting lug 41 of the shock absorber connection code 4, and the connecting hole 42 of the shock absorber connection code 4 is fixedly connected to the direct mounting position 31 on the shock absorber mounting block 3 by bolts or pins. Simultaneously, the rear fork connection end 52 of the shock absorber 5 is directly connected to the shock absorber connection position 22 of the rear fork 2. This connection position 22 can be a lug or a pin hole, ensuring that the shock absorber 5 directly bridges the frame 1 and the rear fork 2, forming a linear damping structure. At this time, the rocker arm linkage connection position 12 and the rocker arm mounting position 32 can be left idle or covered for protection. This embodiment has a simple structure and is suitable for low-intensity off-road scenarios. The shock absorber 5 directly responds to the swing of the rear fork 2, providing rapid shock absorption and rear fork recovery response.

[0025] Shock-absorbing cradle type implementation method: such as Figure 3 and Figure 4As shown, in this mode, the frame connection end 51 of the shock absorber 5 is also connected to the connecting ear 41 of the shock absorber connection code 4, but the connecting hole 42 of the shock absorber connection code 4 is fixedly connected to the rocker arm mounting position 32 on the shock absorber mounting block 3. Simultaneously, a shock absorber rocker arm linkage 6 is introduced, which includes a link 7 and a rocker arm 8. One end of the link 7 is connected to the rocker arm linkage connection position 12 of the frame 1 via a pin or bolt, and the other end of the link 7 is connected to one end of the rocker arm 8; the other end of the rocker arm 8 is connected to the rear fork connection end 52 of the shock absorber 5, while the middle position of the rocker arm 8 is connected to the shock absorber connection position 22 of the rear fork 2. This linkage mechanism forms a lever system, achieving progressive damping characteristics, and the shock absorber 5 indirectly absorbs the impact of the rear fork 2 through the rocker arm linkage. This implementation is suitable for high-intensity off-road environments, effectively copes with large impact forces, and provides better support and comfort.

[0026] In practical applications, users can switch between different shock absorption structures without replacing the frame 1, by selecting different mounting positions and adding or removing the shock-absorbing rocker arm linkage 6, based on terrain requirements. For example, switching from a direct-mount to a rocker-arm type only requires adjusting the mounting position of the shock absorber connector 4, adding the linkage 7 and rocker arm 8, and connecting the components accordingly. This design improves the frame's versatility, reduces upgrade costs, and meets personalized riding needs.

[0027] This utility model provides a technical solution for off-road motorcycle frames that can adapt to both direct-mount and rocker-mount shock absorber structures by setting shock absorber mounting blocks (including direct-mount mounting position 31 and rocker mounting position 32) and rocker linkage connection position 12 on the frame 1. This solves the problem that existing frames only support a single shock absorber structure and it is difficult to adjust or replace the shock absorber structure without changing the frame.

[0028] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
