Detailed ways

Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

In the present disclosure, unless stated to the contrary, the used orientation words such as "upper and lower" generally refer to the definition based on the drawings of the corresponding drawings, and "inner and outer" refer to the contours of the corresponding components. inside and out.

1 and 2, the shock-absorbing bicycle wheel of the present embodiment includes a wheel shaft 1, a spoke 2, a rim 4 and a tire 5, and the spoke 2 is a shock absorber; the shock absorber is arranged along the eccentric direction of the wheel. When people pedal hard, the wheel shaft 1 driven by the chain drives the rotation of the wheel, and the shock absorber drives the wheel to rotate, and the rear wheel starts to rotate, and then the front wheel also rotates. When riding on an uneven road surface, or other trivial things such as stones, the traditional bicycle will make people feel a little bumpy, making the rider uncomfortable and easy to hurt the body. The utility model shock-absorbing wheel overcomes the above problems and can greatly improve the riding comfort of the rider. When running into uneven road surface, the tire 5 first contacts with the road surface, and at this moment, under the combined action of the shock absorber in the wheel, the rider feels less vibration and improves riding comfort. The eccentricity of the shock absorber relative to the wheel radius is 0-20mm, excluding the endpoint value of 0mm; when the bicycle is in working condition, the three shock absorbers of the wheel will have a certain degree of interaction force, set the maximum eccentricity 20mm to achieve the theoretical bearing capacity.

For example, in the solution of this embodiment, a hub is also arranged on the wheel shaft 1, three connecting holes are evenly arranged on the hub, three rim connectors 3 are evenly arranged on the rim 4, and there are three shock absorbers; , drive the rear axle 1 to rotate through the chain, and then drive the hub to rotate, the hub drives the shock absorber to rotate through the pin, the shock absorber drives the wheel to rotate, the rear wheel starts to rotate, and then the front wheel also rotates. The three shock absorbers are respectively connected to the connection hole and the rim connector. The eccentricity of the shock absorber relative to the wheel radius is 20mm. The specific setting of the three shock absorbers is that the three shock absorbers on one wheel usually pass through The interaction can ensure the normal working state of the bicycle when riding. Four or more are also possible, but the difficulty of processing the axle and rim is greatly increased, which brings inconvenience to manufacturing.

In the embodiments of the present disclosure, the shock absorbers installed on the shock absorbing wheels may be common shock absorbers in the prior art, such as ordinary shock absorbers such as Xiaoguiwang shock absorbers. As long as the rotation of the wheels can be satisfied and a certain damping effect can be achieved.

Preferably, in an embodiment of the present disclosure, the shock absorber used on the damping wheel can also be the shock absorber of the structure shown in Figure 2, the shock absorber includes a buffer shaft and a buffer cavity 25, the buffer shaft and the buffer The cavity 25 realizes axial buffering and shock absorption through the spring member arranged on the outer periphery of the buffer cavity 25 and in the buffer cavity 25 . The shock absorber in this solution is mainly to achieve the best buffering effect under the joint action of the spring member and the buffer shaft, and the spring members are all types with relatively large strength and damping coefficient. The outer circumference and the inside of the buffer cavity 25 have axial buffering force, and the two cooperate with each other, which is more conducive to giving a buffering force to the rotating wheel.

The buffer shaft includes a first buffer shaft 22 and a second buffer shaft 23 arranged in sequence in the axial direction, the diameter of the first buffer shaft 22 is greater than the diameter of the second buffer shaft 23; the spring member includes a first spring 24 and a second spring 26, The first spring 24 is sleeved outside the buffer chamber 25, and the second spring 26 is arranged in the buffer chamber 25; the buffer chamber 25 is a cavity with closed ends, and the second buffer shaft 23 extends into the buffer chamber from the closed end of the buffer chamber 25 25 and connected with the second spring 26; the first buffer shaft 22 is axially connected with the first spring 24. Preferably, the second buffer shaft 23 is axially connected with the second spring 26 . The end of the first buffer shaft 22 is a first connecting piece 21 (such as a shaft hole), which can be connected with the connecting hole on the hub through a shaft or a pin. The second buffer shaft 23 has a slightly larger head, and the others are Regular cylindrical members, the slightly larger end of the head of the second buffer shaft 23 extends into the buffer chamber 25, the shape of the buffer chamber 25 can be set in accordance with the shape of the slightly larger head of the second buffer shaft 23, and the closed buffer chamber 25. On the one hand, prevent the second buffer shaft 23 from being pulled out of the buffer cavity 25 due to a large force, and on the other hand, prevent the second buffer shaft 23 from driving the second spring 26 to move too far, exceeding the elastic limit of the second spring 26, result in damage to the second spring 26. Therefore, the arrangement of the above-mentioned components in this embodiment can not only realize the axial and partial radial buffering movement, but also the cooperation between the various components increases the service life of the overall shock absorber component, and mutually Protect. Then, a shaft hole is provided on the second connecting member 26 (such as a shaft with a shaft hole) to connect to the rim 4 .

A buffer pad 251 is pasted on the inner wall of the buffer cavity 25 , and the second spring 26 is also connected to the adjusting member 27 . Part of the external force can also be counteracted by the elastic gasket in the form of the buffer pad 251 to play a buffering role. When the bicycle has been ridden for a long time, the spring will inevitably be affected. At this time, the effect of the adjusting member 27 can be considered, mainly to adjust the compression distance of the second spring 26. For example, the adjusting member 27 is an adjusting nut, so that the second spring 26 Have a certain degree of tension. In addition, the position of setting the adjusting part 27 is on the second connecting part 28, and the second connecting part 28 is provided with a connecting hole for installing the shock absorber on the rim connecting part 3 on the rim 4, and the rim connecting part 3 is substantially The upper part is an extension plate body with a connection hole, the main function is to connect one end of the shock absorber, which can be connected by a nut or a pin shaft, and at the same time, the adjustment part 27 can also be hidden in the second connection part 28, For example, a through hole is provided at the end of the second connecting member 28 without a connecting hole, and an adjusting member 27 is arranged axially in the hole, and the adjusting member 27 and the second spring 26 are tightened.

A shock-absorbing bicycle includes wheels, which are bicycle shock-absorbing wheels in this embodiment.
