DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor are involved in the protection scope of the utility model.

[0023] A seat stand with damping function is mainly used to absorb vibration, improve the comfort of riding or sitting posture, relieve the discomfort caused by long time sitting posture, and enhance the stability and support effect of the seat. The design makes the stand adapt to different riding environments and user needs, thereby improving the overall use experience.

[0024] The existing device only realizes damping through the spring assembly, which can cause the seat to shake more when riding. The main reason is that the main function of the spring is to store and release energy, but there is no proper damping. After being impacted, the spring will rebound and produce vibration, and this vibration will last for a period of time, thereby causing the seat to shake up and down when riding. Please refer to Figures 1-4 The embodiment provides a seat stand with damping function, which comprises a seat 1 and a stand 2 arranged at the bottom of the seat 1, and forms a supporting and connecting relationship.

[0025] Reference Figure 2As shown, the existing device only achieves shock absorption through the spring assembly, which can cause the seat to shake more when riding. The main reason is that the main function of the spring is to store and release energy, but without proper damping, the spring will rebound and produce vibration after being impacted. This vibration will last for a period of time, causing the seat to shake up and down when riding. In order to achieve shock absorption for the seat 1, the following settings are made. The inside of the vertical rod 2 is provided with a buffer assembly 3 for shock absorption of the seat 1. The buffer assembly 3 includes a connecting rod 31 sleeved inside the vertical rod 2. The inside of the vertical rod 2 is provided with a limiting assembly for guiding the connecting rod 31 to slide along the inner wall. The limiting assembly includes a sliding block fixed to the outer wall of the connecting rod 31. The inner wall of the vertical rod 2 is provided with a sliding groove. The sliding block slides up and down along the height direction of the sliding groove. The seat 1 is fixed to the top end of the connecting rod 31. The bottom end of the connecting rod 31 is provided with a shock absorbing spring 32 and a damper 33. The shock absorbing spring 32 is sleeved on the outer wall of the damper 33. The two ends of the shock absorbing spring 32 and the damper 33 are fixedly connected with the connecting rod 31 and the vertical rod 2 respectively. During riding, due to human movement and external environmental factors, the bicycle is prone to large vibration. At this time, the connecting rod 31 extrudes the shock absorbing spring 32 and the damper 33 in the vertical rod 2. The shock absorbing spring 32 is compressed to absorb part of the energy. The elasticity of the shock absorbing spring 32 enables it to deform when subjected to external force and return to its original shape after the external force is removed, thereby reducing the transmission of vibration to the seat 1. The compressed shock absorbing spring 32 slowly releases the stored energy during the recovery process, thereby helping the seat 1 to return smoothly to the original position and reducing the impact of vibration on the rider. The damper 33 absorbs vibration energy by the flow of liquid or gas and converts it into heat energy, thereby effectively reducing the amplitude of vibration. At the same time, the damper 33 can control the rebound speed of the shock absorbing spring 32 to prevent additional vibration caused by excessive rebound. The resistance provided can reduce the vibration amplitude of the shock absorbing spring 32 and reduce the frequency of vibration, making the seat 1 more stable during riding and increasing comfort. Through the dispersion and absorption of the shock absorbing spring 32 and the damper 33, the possibility of resonance is reduced, thereby reducing the shaking of the seat 1. Under different riding conditions (such as flat road and bumpy road), the movement of the connecting rod 31 enables the shock absorbing spring 32 and the damper 33 to dynamically adjust, providing corresponding shock absorption effect. Through the combination of the two, different frequencies and amplitudes of vibration can be effectively dealt with, enabling the rider to better maintain stability on uneven roads and reducing the impact of vibration on the body, thereby improving the overall riding comfort.

[0026] Reference Figure 3 As shown, the top end of the vertical rod 2 is provided with a foldable cover pipe 5 for protecting the buffer assembly 3. The foldable cover pipe 5 is sleeved on the outer wall of the connecting rod 31. The two ends of the foldable cover pipe 5 are fixedly connected with the vertical rod 2 and the connecting rod 31 respectively, preventing dust in the external environment from being brought into the vertical rod 2 when the connecting rod 31 extends and retracts in the vertical rod 2, thereby ensuring the normal work and shock absorption effect of the buffer assembly 3.

[0027] Reference Figure 4 As shown, the inner wall of the stackable pipe 5 is adhesively fixed with a stackable elastic piece 6 used to assist the resetting of the connecting rod 31. The presence of the stackable elastic piece 6 provides additional resetting assistance for the connecting rod 31, reduces the working burden of the shock absorbing spring 32, and reduces the force required for resetting, thereby not only improving the resetting performance of the connecting rod 31, but also improving the overall shock absorbing effect and making the ride more comfortable.

[0028] Reference Figure 4 As shown, the inside of the seat 1 is provided with a anti-shake component 4 used to improve the comfort of the rider's hips, which includes a skin layer body 41 that provides a soft surface and increases the comfort of the touch. The bottom of the skin layer body 41 is provided with a rubber pad layer 42 that plays a buffering role and can effectively absorb vibration and impact, further reducing the impact on the hips during riding. The bottom of the rubber pad layer 42 is provided with a silica gel filling layer 43. Since silica gel has excellent elasticity and buffering performance, it can provide better support and further improve comfort. The bottom of the silica gel filling layer 43 is provided with a seat skeleton 44 that provides support and stability for the overall structure. This multi-layer design combines the advantages of different materials, so that the anti-shake component 4 can significantly improve the comfort of the rider's hips and reduce the discomfort caused by uneven road surfaces.

[0029] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
