[0035] The utility model provides a shock absorber for a jumping motorcycle, which is used in shock absorber design. The utility model does not limit the type of use scene, but the structure of the shock absorber for a jumping motorcycle is particularly suitable for shock absorbers for motorcycles.

[0036] In general, the shock absorber for jumping motorcycle proposed in the utility model mainly includes an oil storage cylinder 1, a connecting seat 2, a piston rod 3, a mounting ring 4, a spring 5, and a buffer block 6. Figure 1 , which shows the arrangement relationship of the oil storage cylinder 1, the connecting seat 2, the piston rod 3, the mounting ring 4, the spring 5, and the buffer block 6.

[0037] In order to achieve the purpose of improving the performance of shock absorbers for off-road motorcycles, the problem in the background technology that although off-road vehicles require higher supporting force, the shock absorbers also need to ensure the comfort of the rider to avoid unnecessary fatigue to the rider during long-term bumpy driving is solved. However, the existing shock absorbers for motorcycles cannot ensure that the shock absorbers have a reasonable buffering effect during jumping and bumping, and at the same time, can protect the shock absorber's own structure from being damaged by high-intensity impact. For this reason, in the technical solution provided in this embodiment, a 360° rotation of the connecting main shaft is achieved through a connecting seat 2 installed at the end of the oil storage cylinder 1, and a buffer block 6 is installed on the piston rod 3, so that the shock absorber can adapt to the impact caused by bumps and shocks during the jumping process of the motorcycle, so as to achieve the effect of adaptively adjusting the position, and protect the piston rod 3 to avoid the phenomenon of hard collision.

[0038] Specifically, Figure 1As shown, in the overall structure, the connecting seat 2 is installed on one axial end of the oil storage cylinder 1, and the other end of the oil storage cylinder 1 is inserted and installed with a piston rod 3. The mounting ring 4 is connected to the end of the piston rod 3 away from the oil storage cylinder 1 through a thread. The spring 5 is sleeved and installed on the outside of the oil storage cylinder 1. When the piston rod 3 moves, the spring 5 is pressed between the oil storage cylinder 1 and the piston rod 3.

[0039] like Figure 2 As shown, in order to realize the movement of the piston rod 3 and thereby adjust the movement of the oil and gas in the oil storage cylinder 1 to achieve the buffering effect of the shock absorber, the piston rod 3 is connected to the oil storage cylinder 1 in sequence through the piston 10 and the guide sleeve 11.

[0040] As mentioned above, since the shock absorber provided in this embodiment is suitable for off-road type motorcycles, the usage scenarios may encounter jumping, bumps and the like. In order to improve the shock absorbing effect of the shock absorber, an upper spring seat 7 is installed on the outer circumference of the side of the oil storage cylinder 1 away from the mounting eye 4, and correspondingly, a lower spring seat 8 is provided on the end of the mounting eye 4 close to the oil storage cylinder 1, and the two ends of the spring 5 are respectively connected to the upper spring seat 7 and the lower spring seat 8; in addition, the outer diameter of the spring 5 is larger than the outer diameter of the upper spring seat 7 and the lower spring seat 8. When the outer diameter of the spring 5 is larger than the outer diameter of the spring seat, the structure helps to ensure the correct assembly and fixation of the spring 5 in the shock absorber.

[0041] On this basis, in order to avoid the piston rod 3 from colliding with the oil storage cylinder 1 during the movement and adjustment process, thereby reducing the service life of the piston rod 3 and avoiding breakage, a deformable buffer block 6 made of rubber material is provided. The buffer block 6 is installed on the side of the piston rod 3 close to the mounting ring 4 and is located on the outside of the oil storage cylinder 1. Specifically, the buffer block 6 is provided with a conical structure, and the outer diameter gradually decreases as it approaches the side of the oil storage cylinder 1, and annular grooves 9 are evenly spaced on the outer circumference of the buffer block 6. When the buffer block 6 is squeezed, local deformation occurs at the annular grooves 9, and a buffer can be formed by the annular grooves 9 to facilitate the dispersion of stress. This deformation ability helps the buffer block 6 to more effectively absorb and reduce the impact force when it is impacted, thereby protecting the shock absorber from damage.

[0042] It should be specifically explained that the connecting seat 2 provided in this embodiment includes a connecting seat body 21, a main shaft mounting hole 22, and a bearing sleeve 23, wherein the connecting seat body 21 is sleeved and bolted on the connecting structure 12 at the end of the oil storage cylinder 1, and the connecting seat body 21 is also provided with a coaxially arranged main shaft mounting hole 22 at the opening of the connecting structure corresponding to the connecting structure. In order to realize 360-degree rotation of the main shaft after installation, the bearing sleeve 23 is installed in the main shaft mounting hole 22, and the two ends of the main shaft are also respectively installed on the bearing sleeve 23 through the sleeve clamp. When in use, the main shaft installed through the bearing sleeve 23 can rotate along its own center axis.

[0043] Furthermore, a retaining spring 24 is provided between the bearing sleeve 23 and the spindle mounting hole 22. The retaining spring 24 can clamp the bearing sleeve 23 in the connecting seat 2 to avoid relative movement between the bearing sleeve 23 and the spindle mounting hole 22 during use.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
