[0001] The utility model relates to the technical field of bicycle frames, in particular to a frame with a shock-absorbing function. Background Art

[0002] In order to alleviate air pollution and urban traffic pressure, bicycle travel has become an increasingly popular green and healthy travel method. Bicycles have the advantages of being environmentally friendly and convenient. While they are a means of transportation, they can also play a role in fitness. In the prior art, bicycle frames do not have a shock-absorbing function or have a relatively weak shock-absorbing function. Therefore, when riding a bicycle through a road section with poor road conditions, it is easy to produce large bumps, affecting the comfort and safety of riding. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of the utility model is to provide a frame with a shock-absorbing function, which is used to solve the problem in the prior art that the bicycle frame has no shock-absorbing function or the shock-absorbing function is relatively weak, so when riding a bicycle through a section with poor road conditions, it is easy to produce large bumps.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0005] A frame with a shock-absorbing function comprises a frame body and a shock-absorbing device arranged on the frame body, wherein the frame body comprises a middle tube, a transverse tube arranged at the upper end of the middle tube, an oblique tube arranged at the lower end of the middle tube, and a head tube connecting the transverse tube and the oblique tube, and the middle tube, the transverse tube, the oblique tube and the head tube together form a tripod structure; a rear axle assembly is hinged rearwardly at the middle portion of the middle tube, and the rear axle assembly is connected to the oblique tube through the shock-absorbing device.

[0006] To implement the above technical solution, the middle tube, transverse tube, oblique tube and front tube are all hollow cylinders, which can reduce the weight of the frame body and have high strength. The middle tube, transverse tube and oblique tube form a tripod structure, which has stability, and the frame body is not easy to deform. By setting the shock-absorbing device, the comfort of riding on complex terrain can be improved, the comfort of the human body can be improved, and the vibration felt by the human body can be reduced. The frame structure is scientifically and reasonably designed, light in weight, high in stability, and good in shock-absorbing effect.

[0007] In one embodiment of the utility model, the rear axle assembly includes two rear axle tubes symmetrically hinged on the middle tube, and the ends of the two rear axle tubes away from the middle tube are provided with axle seats for mounting rear wheels, and the two axle seats are provided with shock-absorbing tubes symmetrically on both sides of the middle tube, and the shock-absorbing device is hinged on the shock-absorbing tubes.

[0008] To implement the above technical solution, the axle seat is used to install the rear wheel, and the lower end of the head tube is used to install the front wheel. The structure of the present application is reasonable, and the shock absorbing device is installed at the lower end of the cross tube, which does not occupy the riding space. When the front wheel or the rear wheel encounters vibration, the shock absorbing device can effectively reduce and absorb shock.

[0009] In one embodiment of the utility model, the shock absorbing device includes two mounting blocks symmetrically arranged on both sides of the inclined tube, a shock absorber with one end hinged on the mounting block and the other end hinged on the inclined tube, and a shock absorbing spring mounted on the shock absorber.

[0010] To implement the above technical solution, in the prior art, shock-absorbing springs are generally used for shock absorption. When a vehicle passes over an uneven road surface, although the shock-absorbing spring can filter out the vibration of the road surface, the shock-absorbing spring itself will still have reciprocating motion. Therefore, the shock-absorbing device in the present application also includes a shock absorber for suppressing the shock-absorbing spring, preventing the shock-absorbing spring from rebounding after absorbing the vibration, and reducing the impact from the road surface, thereby improving riding comfort.

[0011] In one embodiment of the utility model, one end of the mounting block is fixed on the inclined tube, the shock absorbing tube is hinged at the middle of the mounting block, and the shock absorber is hinged at the other end of the mounting block.

[0012] To implement the above technical solution, when the rear wheel encounters vibration, the vibration is transmitted to the shock absorbing tube, the shock absorbing tube transmits the vibration to the mounting block, and the mounting block transmits the vibration to the shock absorber and the shock absorbing spring, thereby achieving a shock absorbing effect.

[0013] In an embodiment of the present invention, a scissor-shaped support rib is provided between the transverse tube and the oblique tube.

[0014] By implementing the above technical solution, the support ribs can increase the strength of the frame body and enable the frame body to withstand a larger load without being easily deformed.

[0015] In an embodiment of the present invention, a connecting plate is connected between the two shock absorbing tubes.

[0016] To implement the above technical solution, the connecting plate is used to connect the two shock absorbing tubes to ensure the stability and reliability of the shock absorbing tubes.

[0017] In an embodiment of the present invention, the frame body is made of carbon fiber, aluminum alloy or titanium alloy.

[0018] To implement the above technical solution, the characteristics of a bicycle made of carbon fiber are that it is more elastic, has a stable riding feel, can be made into a lightweight frame, has good impact absorption, and can be made into frames of various shapes; a bicycle made of aluminum alloy has a more sensitive, light, and high rigidity riding feel; the characteristics of titanium alloy are more like a combination of aluminum alloy and carbon fiber. It can have elasticity similar to carbon fiber and also enjoy the lightness and rigidity of aluminum alloy.

[0019] As described above, the utility model is a frame with shock-absorbing function, which has the following beneficial effects: the middle tube, the cross tube and the oblique tube form a tripod structure, which is stable and high in strength, and the frame body is not easy to deform. By setting the shock-absorbing device, the comfort of riding on complex terrain can be improved, the comfort of the human body can be improved, and the vibration felt by the human body can be reduced. The frame structure is scientifically and reasonably designed, light in weight, highly stable, and has a good shock-absorbing effect. BRIEF DESCRIPTION OF THE DRAWINGS
