[0020] The utility model provides Figure 1-3 The electric bicycle shock absorbing device shown in the figure comprises a U-shaped rod 1, a fixing rod 2 is installed on the upper end of the U-shaped rod 1, a lifting sleeve 3 is provided on both sides of the lower end of the U-shaped rod 1, the lower end of the U-shaped rod 1 extends into the lifting sleeve 3, and shock absorbing springs 4 are sleeved on both sides of the lower end of the U-shaped rod 1, characterized in that an auxiliary shock absorbing mechanism is installed on the lifting sleeve 3, and an adjusting mechanism is installed on the U-shaped rod 1; the auxiliary shock absorbing mechanism comprises a long groove 5 located on both sides of the lower end of the U-shaped rod 1, a pressing block 6 is installed on one side of the upper end of the lifting sleeve 3, an adjusting port 7 is opened at the upper end of the lifting sleeve 3, one end of the pressing block 6 passes through the adjusting port 7 and extends into the long groove 5, and there is friction between the pressing block 6 and the long groove 5; the adjusting mechanism comprises a pushing frame 8 installed on both sides of the upper end of the U-shaped rod 1, the pushing frame 8 can push the pressing block 6 in the direction close to the long groove 5, and an adjusting frame 9 is installed on the upper end of the lifting sleeve 3, and the adjusting frame 9 can adjust the friction between the pressing block 6 and the long groove 5;

[0021] The process of shock absorption of the electric bicycle by this device is as follows: before using the electric bicycle, the position of the clamping block 6 is first adjusted by the adjustment frame 9, and the shock absorption effect of the electric bicycle can be adjusted by changing the friction between the clamping block 6 and the long groove 5. During the driving of the electric bicycle, when encountering bumpy ground, preliminary shock absorption can be performed by the friction between the clamping block 6 and the U-shaped rod 1, and shock absorption can also be performed by the shock-absorbing spring 4. Double shock absorption has a better effect. When the vibration force is too large, the clamping block 6 can be pushed again by the pushing frame 8, thereby increasing the shock absorption effect again. When the electric bicycle has been used for a period of time and wear occurs between the clamping block and the U-shaped rod 1, the position of the clamping block 6 can be adjusted by the adjustment frame 9 to adjust the shock absorption effect.

[0022] Refer to the instruction manual Figure 3 The pressing block 6 includes a square friction block 10 located on the inner side of the lifting sleeve 3. One side surface of the square friction block 10 contacts the inner surface of the long groove 5. A limiting rod 11 is installed on the other side surface of the square friction block 10. One end of the limiting rod 11 passes through the adjustment port 7 and extends to the outside of the lifting sleeve 3. The limiting rod 11 can limit the square friction block 10 to prevent the square friction block 10 from moving at will.

[0023] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 And the instruction manual Figure 3 The adjusting frame 9 includes an adjusting plate 12 installed on the outside of the limiting rod 11, a circular hole 13 is opened on the adjusting plate 12, an adjusting screw 14 installed on the lifting sleeve 3 is provided on one side of the circular hole 13, one end of the adjusting screw 14 passes through the circular hole 13 and extends to the outside of the adjusting plate 12, the adjusting screw 14 is connected to the adjusting nut 15 by a thread, and the adjusting plate 12 and the lifting sleeve 3 are connected by a telescopic spring 16;

[0024] The process of adjusting the position of the clamping block 6 by the adjusting frame 9 is as follows: the adjusting plate 12 is mounted on the adjusting screw 14, and the adjusting nut 15 is screwed on the adjusting screw 14, so that the adjusting plate 12 can be pushed toward the direction close to the lifting sleeve 3, and the square friction block 10 is pushed toward the direction close to the long groove 5 through the limiting rod 11, so as to increase the friction force and increase the shock absorption effect. When it is necessary to reduce the friction force, the adjusting nut 15 is rotated in the opposite direction, and the telescopic spring 16 can push the adjusting plate 12 outward, and then drive the limiting rod 11 and the square friction block 10 to push outward, so as to reduce the friction force.

[0025] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 And the instruction manual Figure 3The push frame 8 includes a trapezoidal platform 17 located on both sides of the U-shaped rod 1, a rectangular platform 18 is installed at the front end of the trapezoidal platform 17, a pulley 19 is installed on the outer surface of the adjustment plate 12, one end of the pulley 19 is supported on the rectangular platform 18, the trapezoidal platform 17 is connected to the upper end of the U-shaped rod 1 through a connecting rod 20, a limit ring 21 is installed on one side of the upper end of the lifting sleeve 3, a universal ball 22 is installed on the inner side of the limit ring 21, and the rectangular platform 18 can pass through the inner side of the universal ball 22;

[0026] The process of the pushing frame 8 pushing the clamping block 6 is as follows: under normal conditions, the rectangular platform 18 is located on one side of the pulley 19. When the electric bicycle vibrates too much, the U-shaped rod 1 can be moved downward, and the trapezoidal platform 17 and the rectangular platform 18 can be driven to move downward through the connecting rod 20. When the inclined surface position of the trapezoidal platform 17 moves to the pulley 19, the pulley 19 and the adjustment plate 12 can be pushed, thereby increasing the friction between the square friction block 10 and the long groove 5, and enhancing the shock absorption effect. The limit ring 21 can limit the rectangular platform 18 to prevent the rectangular platform 18 from shaking, and the universal ball 22 can reduce the friction when the rectangular platform 18 moves.

[0027] Refer to the instruction manual Figure 3 A circular limiting plate 23 is installed at the upper end of the lifting sleeve 3, and baffles 24 are installed on both sides of the lower end of the U-shaped rod 1. The baffle 24 is located on the inner side of the lifting sleeve 3. The circular limiting plate 23 can limit the baffle 24 to prevent the U-shaped rod 1 from moving out of the lifting sleeve 3.
