[0031] The present invention is further described in detail below with reference to the embodiments given in the accompanying drawings.

[0032] like Figures 1 to 5 As shown, a rear shock absorbing mechanism of a scooter described in this embodiment includes a body 1, a rear wheel 2, and left and right leaf springs 3, 4. The left and right leaf springs 3, 4 are respectively provided with a first axle connection portion 31, 41 at one end, and a second axle connection portion 32, 42 at the other end. The first axle connection portions 31, 41 of the left and right leaf springs 3, 4 are respectively axle connection to the body 1, and the second axle connection portions 32, 42 of the left and right leaf springs 3, 4 are respectively axle connection to the left and right sides of the rear wheel 2, and the left and right leaf springs 3, 4 are both arc-shaped leaf springs that arch upward from both ends to the middle.

[0033] It also includes a limit adjustment screw 7, a locking nut 8 and left and right adjustment slots 9 and 10. The left and right adjustment slots 9 and 10 are respectively arranged on the left and right side walls 11 and 12 of the rear of the vehicle body 1. The limit adjustment screw 7 passes through the left and right adjustment slots 9 and 10 horizontally and can move therein. The limit adjustment screw 7 is also pressed on the upper side of the left and right leaf springs 3 and 4. The locking nut 8 is screwed on the threaded end of the limit adjustment screw 7. When the damping amplitude needs to be adjusted, the locking nut 8 is loosened, and then the limit adjustment screw 7 is moved to press the corresponding position of the left and right leaf springs 3 and 4, and then the locking nut 8 is tightened to achieve the purpose of this adjustment. Specifically, the further back the position of the limit adjustment screw 7 is, the harder the left and right leaf springs 3 and 4 are, and the smaller the damping amplitude is. Conversely, the more forward the position of the limit adjustment screw 7 is, the softer the left and right leaf springs 3 and 4 are, and the larger the damping amplitude is.

[0034] It also includes left and right sliders 30, 40, which are respectively slidably mounted on the left and right leaf springs 3, 4, and the upper parts of the left and right sliders 30, 40 are respectively provided with a first through hole 301 and a second through hole 401, and the limit adjustment screw 7 also passes through the first through hole 301 and the second through hole 401, thereby achieving the pressing of the left and right leaf springs 3, 4. In this structure, the arrangement of the left and right sliders 30, 40 can ensure that the left and right ends of the limit adjustment screw 7 are flush when the position is adjusted, and prevent the phenomenon that one end is closer to the front and the other end is closer to the back. Further, in order to facilitate the installation of the left and right sliders 30, 40, the lower parts of the left and right sliders 30, 40 are respectively provided with sleeves 301, 401 opening toward the outside, and the left and right sliders 30, 40 are respectively slidably mounted on the left and right leaf springs 3, 4 through their upper sleeves 301, 401.

[0035] A shock absorbing limit limit buffer pad 50, 60 is respectively arranged on the inner surface of the left and right side walls 11, 12 of the rear part of the vehicle body 1 corresponding to the upper rear ends of the left and right leaf springs 3, 4 to prevent the left and right leaf springs from bending and deforming too much during shock absorption.

[0036] In order to facilitate manufacturing and installation, the first axle connection parts 31, 41 and the second axle connection parts 32, 42 of the left and right leaf springs 3, 4 are both annular bodies integrally formed with the leaf spring body.

[0037] A first fixed shaft 5 located in front of the limit adjustment screw 7 is detachably straddled on the left and right side walls 11 and 12 of the rear of the vehicle body 1. The first shaft connection parts 31 and 41 of the left and right leaf springs 3 and 4 are respectively fixedly mounted on the two ends of the first fixed shaft 5 and are respectively located on the inner sides of the left and right side walls 11 and 12 of the rear of the vehicle body 1. The left and right sides of the rear wheel 2 are respectively provided with a first shaft hole seat 201 and a second shaft hole seat 202, and also include a second fixed shaft 6 that transversely penetrates the first shaft hole seat 201 and the second shaft hole seat 202. The left and right ends of the second fixed shaft 6 are exposed and both are provided with external threads. The second shaft connection parts 32 and 42 of the left and right leaf springs 3 and 4 are respectively mounted on the left and right exposed ends of the second fixed shaft 6, and each is locked by a nut 600. This structure can realize the simple disassembly and assembly of the leaf spring, and is convenient for the repair and replacement of the leaf spring when it is damaged or reaches the end of its service life.

[0038] Furthermore, the first fixed axis 5, the second fixed axis 6 and the limit adjustment screw 7 are parallel to each other, and the position of the limit adjustment screw 7 is higher than the first fixed axis 5, and the position of the first fixed axis 5 is higher than the second fixed axis 6. In other words, the axial connection position between the first axial connection parts 31, 41 of the left and right leaf springs 3, 4 and the vehicle body 1 is higher than the axial connection position between the second axial connection parts 32, 42 of the left and right leaf springs 3, 4 and the rear wheel 2, which can further increase the ground clearance of the vehicle body and ensure the vehicle's passability.

[0039] like Figure 1 and Figure 4As shown, a scooter described in this embodiment includes the above-mentioned scooter rear shock absorbing mechanism, and also includes a handlebar 200, a front wheel 300 and a rear fender 400. The front wheel 300 is arranged at the lower end of the handlebar 200. The handlebar 200 is connected to the front end of the vehicle body 1 through a connecting member 500. The vehicle body 1 includes a vehicle body shell 101 with an open top and a vehicle body cover 100 covering the top of the vehicle body shell 101. The rear fender 400 covers the upper part of the rear wheel 2. The front end of the scooter 00 is fixed to the rear end of the body cover 100, and the body shell 101 includes a front compartment 700a and a rear compartment 700b separated by a partition 700, the front compartment 700a is provided with a lithium battery and a controller, the rear shock absorbing mechanism of the scooter is provided in the rear compartment 700b, and the rear end of the rear compartment 700b is provided with a first opening 700b1 for the front part of the rear wheel 2 to extend into the rear compartment, and the rear end of the body cover 100 is provided with a second opening 1001 for the front part of the rear wheel 2 to extend into the rear compartment.

[0040] The above is only a preferred embodiment of the present invention, and should not be used to limit the scope of the present invention. That is, all simple equivalent changes and modifications made according to the scope of the patent application and the content of the invention description of the present invention are still within the scope of the patent of the present invention.
