DETAILED DESCRIPTION

[0016] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0017] like Figure 1-2A front shock absorbing mechanism of a scooter is shown, comprising a scooter front fork 1, a front fork lower riser 2, a front fork upper riser 3, and a spring stopper 4. The front fork lower riser 2 is a hollow tubular structure, and a plug 9 is provided at the top opening. The scooter front fork 1 is fixedly sleeved on the lower part of the front fork lower riser 2, the front fork upper riser 3 is sleeved on the upper part of the front fork lower riser 2, and a bearing copper sleeve 5 is provided between the front fork upper riser 3 and the front fork lower riser 2, and the front fork lower riser 2 can move up and down in the bearing copper sleeve 5.

[0018] The spring stopper 4 has an upper riser fitting portion 41, and the spring stopper 4 is sleeved on the lower end of the front fork upper riser 3 through the upper riser fitting portion 41. A spring 6 is provided between the spring stopper 4 and the scooter front fork 1, and a dust cover 10 is provided on the outer sleeve of the spring 6. A copper sleeve stopper 42 is extended downwardly from the spring stopper 4, and a copper sleeve limiting chamfer 32 is provided in the upper riser 3 of the front fork. The upper end of the bearing copper sleeve 5 abuts against the copper sleeve limiting chamfer 32, and the lower end abuts against the copper sleeve stopper 42.

[0019] It also includes a shock absorbing stroke limit rod 7 and a limit rubber 8. The upper riser matching portion 41 is provided with a limit rod connecting hole 411 in the radial direction. The upper riser 3, the bearing copper sleeve 5 and the lower riser 2 of the front fork are respectively provided with a first through hole 31, a second through hole 51 and an avoidance limit hole 21 corresponding to the position of the limit rod connecting hole 411. The limit rod connecting hole 411 is a threaded hole. The avoidance limit hole 21 is a waist-shaped hole opened in the vertical direction. The first through hole 31 and the second through hole 51 are circular through holes. The shock absorbing stroke limit rod 7 is provided through the first through hole 31, the second through hole 51 and the avoidance limit hole 21 and is screwed into the limit rod connecting hole 411. The limit rubber 8 is cylindrical and its outer diameter is consistent with the inner diameter of the upper part of the lower riser 2 of the front fork. The limit rubber 8 is arranged in the lower riser 2 of the front fork and is located between the plug 9 and the shock absorbing stroke limit rod 7.

[0020] The working principle of the front shock-absorbing mechanism of the scooter is as follows: when riding the scooter, when the front wheel passes over a bumpy road or steps, the front fork 1 of the scooter drives the front fork lower stem 2 to compress the spring 6 upward. After the spring 6 is compressed, a reaction force is generated, which pushes the front fork 1 of the scooter to drive the front fork lower stem 2 to rebound downward, thereby achieving a shock-absorbing effect. When the front fork lower stem 2 moves up and down, the shock-absorbing stroke limit rod 7 moves up and down in the avoidance limit hole 21 relative to the front fork lower stem 2 to limit the movement stroke of the front fork lower stem 2 and the scooter front fork 1. When the front fork lower stem 2 moves upward, the maximum compression amount of the spring 6 and the size design of the avoidance limit hole 21 can ensure that the shock absorbing stroke limit rod 7 does not collide with the lower end of the avoidance limit hole 21 of the front fork lower stem 2; when the front fork lower stem 2 rebounds downward, the shock absorbing stroke limit rod 7 can preferentially contact the limit rubber 8 to prevent the shock absorbing stroke limit rod 7 from directly colliding with the upper end of the avoidance limit hole 21 of the front fork lower stem 2, thereby playing a buffering role, thereby improving the service life of the entire shock absorbing mechanism, reducing noise, and increasing riding comfort.

[0021] During the whole process, the lower front fork tube 2 acts as a guide rod to move up and down in the upper front fork tube 3, and the bearing copper sleeve 5 is arranged between the lower front fork tube 2 and the upper front fork tube 3 as a wear-resistant component to prevent direct contact and wear between the two.
