Description

Technical Field

[0001] The utility model relates to the technical field of folding bicycles, in particular to a quickly foldable bicycle rear suspension system. Background Art

[0002] At present, folding bicycles are becoming more and more popular among consumers due to the demand for convenient carrying and small space occupation. There are also more and more studies on the folding structure of bicycles. However, the current research on folding bicycles focuses more on the folding of handlebars, frames and other parts, but for bicycles with rear suspension systems, there are few designs and studies on the folding of rear suspension systems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a bicycle rear suspension system that can be quickly folded.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A quickly foldable bicycle rear suspension system comprises a flat fork body, a fixing pin and a rotating shaft; the front end of the flat fork body is rotatably connected to a bicycle frame via the rotating shaft, and the rear end of the flat fork body is connected to a bicycle rear wheel; the middle part of the flat fork body is detachably connected to the bicycle frame via the fixing pin.

[0006] Furthermore, a shock absorber is included, and the middle part of the flat fork body is detachably connected to one end of the shock absorber through a fixing pin, and the other end of the shock absorber is connected to the bicycle frame.

[0007] Furthermore, the flat fork body includes two symmetrical halves, each half is located on both sides of the bicycle frame, the front end of each half is rotatably connected to the bicycle frame through a rotating shaft, and the rear end of each half is connected to both sides of the rear wheel of the bicycle; a crossbeam is connected between the two halves; the middle upper ends of the two halves are also connected to fixed seats, and the fixed seats are detachably connected to one end of the shock absorber through a fixing pin.

[0008] The beneficial effect of the utility model is that in the utility model, the entire rear suspension system of the bicycle can be quickly folded only by disassembling the fixing pin, and the utility model has a simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the development of the bicycle rear suspension system in the utility model;

[0010] Figure 2 The utility model is a schematic diagram of the folding of the rear suspension system of the bicycle. DETAILED DESCRIPTION

[0011] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0012] This embodiment provides a bicycle rear suspension system that can be quickly folded. Figure 1 As shown, it includes a fork body 4, a fixing pin 2, a crossbeam 3 and a rotating shaft 1; the front end of the fork body 4 is rotatably connected to the bicycle frame 100 through the rotating shaft 1, and the rear end of the fork body 4 is connected to the bicycle rear wheel 101; the middle part of the fork body 4 is detachably connected to the bicycle frame 100 through the fixing pin 2.

[0013] Specifically, in this embodiment, a shock absorber 5 is also included. The middle portion of the flat fork body 4 is detachably connected to one end of the shock absorber 5 via a fixing pin 2 , and the other end of the shock absorber 5 is connected to the bicycle frame 100 .

[0014] Furthermore, in this embodiment, the flat fork body 4 includes two symmetrical halves, each half is located on both sides of the bicycle frame 100, the front end of each half is rotatably connected to the bicycle frame 100 through the rotating shaft 1, and the rear end of each half is connected to both sides of the bicycle rear wheel 101; a crossbeam 3 is connected between the two halves; the middle upper ends of the two halves are also connected to a fixing seat 6, and the fixing seat 6 is detachably connected to one end of the shock absorber 5 through a fixing pin 2. The above flat fork body structure is lighter while ensuring structural stability, and is more in line with the needs of folding bicycles.

[0015] When in use, the user controls the connection and disconnection of the flat fork body 4 and the shock absorber 5 through the fixing pin 2. When folding is required, the fixing pin 2 is first removed to separate the flat fork body 4 from the shock absorber 5, and then the flat fork body 4 is folded counterclockwise toward the front of the vehicle with the rotating shaft 1 as the axis. Figure 2 As shown, the entire rear suspension system of the bicycle can be quickly folded.

[0016] For those skilled in the art, various corresponding changes and modifications can be made according to the above technical solutions and concepts, and all of these changes and modifications should be included in the protection scope of the claims of the utility model.
