[0003] However, existing bicycles or electric bicycles have poor shock absorption, which causes bumps when encountering uneven roads, resulting in discomfort. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shock-absorbing frame and a shock-absorbing bicycle with good shock absorption effect.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes:

Detailed Implementation

[0024] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0025] like Figure 1 As shown, this utility model discloses a shock-absorbing bicycle frame, including a top tube 1, a top fork 4, and a connecting assembly 8. The top tube 1 is connected to a bottom tube 2 via a head tube 16, and the head tube 16 is fixedly connected to both the top tube 1 and the bottom tube 2. A support tube 13 connects the top tube 1 and the bottom tube 2. The top tube 1 is provided with a first connecting part 3, which has a connecting hole. A bottom fork 5 is provided on one side of the top fork 4, and one end of the top fork 4 is fixedly connected to one end of the bottom fork 5. The other end of the top fork 4 is provided with a second connecting part 6, which has a connecting hole. A shock absorber 7 is provided between the first connecting part 3 and the second connecting part 6, and both ends of the shock absorber 7 are hinged to the first connecting part 3 and the second connecting part 6, respectively. The shock absorber 7 is used to reduce vibrations generated during vehicle operation. To improve the shock absorption effect of the shock absorber 7, the angle between the shock absorber 7 and the top tube 1 is set to 43-45°. More preferably, the angle between the shock absorber 7 and the upper tube 1 is set to 44°.

[0026] The connecting component 8 is connected to the lower fork 5, the support tube 13 and the lower tube 2 respectively, and the connecting component 8 is used to connect the lower fork 5, the support tube 13 and the lower tube 2.

[0027] Based on the above, the connecting component 8 includes a pivot joint and a bottom bracket. In existing automated vehicles, the pivot joint and bottom bracket are separate components connected by welding, resulting in insufficient connection strength. During use, the weld joint between the pivot joint and the bottom bracket is prone to breakage, posing a safety hazard. This application integrates the pivot joint and bottom bracket into a single structure, avoiding breakage at the connection and reducing safety risks.

[0028] Based on the above, a saddle support 9 is provided on the side of the top tube 1 furthest from the head tube. In existing bicycle saddle supports 9, both ends have the same width, which can cause interference during riding; that is, the end of the saddle support 9 near the top tube 1 rubs against the inner thigh, resulting in an uncomfortable riding experience. To address this technical problem, this application sets the width of the end of the saddle support 9 near the top tube 1 to be smaller than the width of the end of the saddle support 9 furthest from the top tube 1. This design avoids the saddle support 9 rubbing against the inner thigh of the rider, providing a more comfortable riding experience.

[0029] In some implementations, to increase the connection strength, a first reinforcing tube 10 is provided between the upper fork 4 and the lower fork 5, and the two ends of the first reinforcing tube 10 are fixedly connected to the upper fork 4 and the lower fork 5 respectively.

[0030] In some implementations, in order to increase the strength of the seat support 9, a second reinforcing tube 11 is provided between the support tube 13 and the seat support 9, and the two ends of the second reinforcing tube 11 are fixedly connected to the support tube 13 and the seat support 9, respectively.

[0031] In some implementation examples, a hook 12 is provided at the connection between the upper fork 4 and the lower fork 5, and the hook 12 is fixedly connected to the upper fork 4 and the lower fork 5 respectively.

[0032] like Figure 2 As shown, another aspect of this utility model discloses a shock-absorbing bicycle, including a shock-absorbing frame, a rear wheel 14 rotatably connected to the hook, and a handlebar and a front wheel 15 connected to the head tube via a connector.

[0033] like Figure 3 As shown, this utility model also discloses a shock-absorbing electric bicycle, including a shock-absorbing frame, a rear wheel rotatably connected to the hook, a handlebar and a front wheel connected to the head tube via a connector, and a battery 17 disposed on the upper tube and / or lower tube, the battery being used to provide power to the electric bicycle.

[0034] It should be understood that the above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
