Description

Technical Field

[0001] The utility model belongs to the technical field of bicycles, and in particular relates to an impact-resistant, shock-absorbing and energy-absorbing bicycle. Background Art

[0002] Bicycles may encounter rough and bumpy roads during riding. Bicycles without a shock absorption system or with poor shock absorption will experience severe bumps, making the rider uncomfortable. The upper fork tube of the rear fork of some shock-absorbing bicycles is connected to the shock absorber through a connecting rod. During shock absorption, the upper fork tube drives one end of the connecting rod, and the other end of the connecting rod compresses the shock absorber. This structure uses the connecting rod to transmit force, and the connecting rod will withstand great impact strength. In addition, the incomplete transfer of force results in a general shock absorption effect. In order to solve this problem, an impact-resistant, shock-absorbing and energy-absorbing bicycle is provided. Utility Model Content

[0005] Furthermore, the upper tube is higher in the front and lower in the back.

[0006] Furthermore, the shock absorber is higher in the front and lower in the back.

[0007] Furthermore, the rear fork is in the shape of an inverted triangle.

[0008] Furthermore, the rear fork rotates around the third pin.

[0009] Compared with the existing technology, this application can achieve the following technical effects:

[0010] The utility model rotates the entire rear fork around the pin shaft, and the rear fork directly compresses the shock absorber, and the bump force received is directly transmitted to the shock absorber, wherein the main connecting rod plays a role in assisting the rotation of the rear fork, thereby enhancing the impact resistance and improving the shock absorption effect.

DETAILED DESCRIPTION

[0017] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a bicycle according to one embodiment of the present invention; Figure 2 It is a schematic diagram of a vehicle frame according to one embodiment of the present invention.

[0019] An impact-resistant, shock-absorbing, and energy-absorbing bicycle comprises: a frame 1; front and rear wheels 2 arranged on the frame 1; a handlebar 3 and a seat 4 arranged on the frame 1; and pedals 5 arranged on the frame 1; the frame 1 comprises a main frame 6, a front fork 7, and a rear fork 8; the main frame 6 comprises a head tube 9, an upper tube 10, a lower tube 11, and a middle tube 12; the rear fork 8 is connected by a symmetrical triangular tube frame through a pin 13, a pin 2 14, and a pin 3 15; the triangular tube frame comprises an upper fork tube 16 , lower fork tube 17 and middle fork tube 18, pin one 13, pin two 14 and pin three 15 are respectively located at both ends and the middle of the middle fork tube 18, the rear fork 8 is connected to one end of the main connecting rod 19 through the pin one 13, and the other end of the main connecting rod 19 is connected to the upper tube 10, the rear fork 8 is connected to the end of the lower tube 11 through the pin three 15, one end of the shock absorber 20 is connected to the lower tube 11, and the other end passes through the slot of the middle tube 12 and is connected to the middle of the middle fork tube 18 through the pin two 14.

[0020] The upper tube 10 is higher at the front and lower at the rear, and the shock absorber 20 is higher at the front and lower at the rear; the rear fork 8 is in an inverted triangle shape; and the rear fork 8 rotates around the pin shaft 3 15 as the center.

[0021] Shock absorption process: When the road surface is bumpy and the rear wheel bounces, the rear fork 8 rotates around the pin shaft 15. The force of the bump is directly transmitted from the rear fork 8 to the shock absorber 20. The main connecting rod 19 assists the rotation of the rear fork 8. After compression, the shock absorber 20 rebounds to offset the bumpy force, thereby achieving a shock absorption effect and improving riding comfort.

[0022] In summary, the present invention rotates the entire rear fork 8 around the pin shaft 3 15, and the rear fork 8 directly compresses the shock absorber 20, and the bumpy force is directly transmitted to the shock absorber 20, wherein the main connecting rod 19 plays a role in assisting the rotation of the rear fork 8, thereby enhancing the impact resistance and improving the shock absorption effect.
