BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is an overall exploded view of the rear shock-absorbing quick-release structure of an electric bicycle in an embodiment of the utility model;

[0010] Figure 2 Detailed schematic diagram of the shock-absorbing quick-release pin in the embodiment of the utility model. 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 rear shock-absorbing quick-release structure for an electric bicycle, such as Figure 1-2 As shown, it includes a flat fork end shock-absorbing connection seat 1, a frame end shock-absorbing connection seat 2, a shock-absorbing quick-release pin 3 and a shock absorber 4; the flat fork end shock-absorbing connection seat 1 is fixed to the flat fork of the electric bicycle, the frame end shock-absorbing connection seat 2 is connected to the frame of the electric bicycle, and the lower end and upper end of the shock absorber 4 are respectively connected to the flat fork end shock-absorbing connection seat 1 and the frame end shock-absorbing connection seat 2; the shock-absorbing quick-release pin 3 includes an indexing pin 31, an indexing pin handle 32 and an adjusting nut 33, and the outer surface of the indexing pin 31 The inner surfaces of the adjusting nut 33 are respectively provided with matching external threads and internal threads; the flat fork end shock-absorbing connecting seat 1 is provided with a mounting groove 11, the lower end of the shock absorber 4 is arranged in the mounting groove 11, one end of the indexing pin 31 is inserted into the mounting groove from one side of the mounting groove 11 to lock the lower end of the shock absorber 4, and the adjusting nut 33 locks and fixes the indexing pin 31; the indexing pin handle 32 is provided at the other end of the indexing pin 31, and is used to move the indexing pin 31 axially. The mounting groove is a U-shaped groove.

[0013] When in use, place the lower end of the shock absorber 4 into the mounting groove 11 of the shock absorber connection seat 1 at the flat fork end, then move the indexing pin handle 32 to move the indexing pin 31 forward and insert it into the mounting groove 11, lock the position of the shock absorber 4, and adjust the locking force of the indexing pin 31 by adjusting the nut 33, so that it is neither loose nor too tight. When the shock absorber needs to be disassembled, the indexing pin handle 32 is moved in the opposite direction to move the indexing pin 31 backward and withdraw from the mounting groove. At this time, the shock absorber can be removed from the mounting groove, and the connection with the flat fork is released, so that the disassembly can be realized quickly.

[0014] 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.
