[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. Through the design of the electric bicycle body, the rear fork, the L-shaped frame and the shock-absorbing mechanism, when the front wheel or the rear wheel is subjected to a bumping vibration force during riding, the vibration force will be transmitted to the electric bicycle body through the front fork, and then the electric bicycle body will rotate at one end of the rear fork and press on one end of the shock-absorbing mechanism to reduce the vibration. If the rear wheel is subjected to a bumping vibration force, the vibration force will be reduced by pressing on one end of the shock-absorbing mechanism during the rotation of the rear fork at one end of the electric bicycle body. In addition, the rider can adjust the softness and hardness of the shock-absorbing mechanism by twisting the spring to achieve the adjustment of the softness and hardness of the shock-absorbing mechanism. The appropriate shock-absorbing hardness helps the rider to maintain a stable riding rhythm in different road conditions, avoids the speed from being too fast or too slow due to too soft or too hard shock-absorbing, and makes the riding more smooth, improving the overall riding efficiency.

[0016] 2. Through the design of the threaded column, the butterfly bolt, the piston column, the spring, the push ring, the limiting rod, the extension plate, the clockwork and the plastic convex ball, when the front fork of the electric bicycle body is subjected to a vibration force transmitted by the wheel, the electric bicycle body will rotate at one end of the rear fork to drive the L-shaped frame to press the piston column to slide into the threaded column, and the piston column will press on one end of the spring during the sliding process to achieve the purpose of shock absorption. If it is necessary to adjust the softness and hardness of the shock-absorbing, the staff can turn over two sets of limiting rods to buckle the plastic convex balls on both sides into the extension plate. The turned limiting rods will slide out of the limiting grooves on the outer surface of the butterfly bolt, thereby releasing the rotational locking of the butterfly bolt, and the butterfly bolt can be twisted and rotated on the outer surface of the threaded column to move up and down. Rotating upwards will push the push ring to move upwards on the outer surface of the threaded column, thereby compressing the spring between the push ring and the second rotating shaft, and thereby increasing the hardness of the shock-absorbing;

[0017] Rotating downwards will release the pressure on the push ring, allowing the push ring to be pushed downwards on the outer surface of the threaded column by the spring to press on the upper surface of the downward rotating butterfly bolt again, thereby increasing the length of the spring between the push ring and the second rotating shaft, and thereby increasing the softness of the shock-absorbing. During the process of pushing the push ring upwards or downwards, the guide blocks fixedly installed on the inner ring wall will vertically slide in the guide grooves on the outer surface of the threaded column. After adjusting the softness and hardness of the vibration, the staff only needs to turn the limiting rod again to slide into the limiting groove of the butterfly bolt to lock the rotation of the butterfly bolt, and the adjustment of the softness and hardness of the vibration is completed.

[0018] During the process of twisting the limiting rod, the limiting rod will be twisted together with the two rotating shafts to twist the clockwork, so that the clockwork exerts a twisting force on the limiting rod to rotate inward, thereby allowing the limiting rod to always slide into the limiting groove of the butterfly bolt by the twisting force of the clockwork.

[0028] Through the design of the electric bicycle body 1, the rear fork 101, the L-shaped frame 104 and the shock-absorbing mechanism 2, when the user is riding and the front wheel or the rear wheel is subjected to a bumping vibration force, the bumping vibration force is transmitted to the electric bicycle body 1 through the front fork, and then the electric bicycle body 1 is pressed at one end of the shock-absorbing mechanism 2 during rotation at one end of the rear fork 101 to perform shock absorption. If the rear wheel is subjected to a bumping vibration force, the bumping vibration force is pressed at one end of the shock-absorbing mechanism 2 during rotation at one end of the electric bicycle body 1 through the rear fork 101 to perform shock absorption. The rider can also adjust the softness and hardness of the shock absorption by twisting the shock-absorbing mechanism 2 to reduce or extend the length of the spring 207 therein. Appropriate shock-absorbing hardness helps the rider maintain a stable riding rhythm under different road conditions, avoids the speed from being too fast or too slow due to too soft or too hard shock absorption, makes the ride smoother, and improves the overall riding efficiency.

[0029] As shown in Figures 5-6 The shock-absorbing mechanism 2 includes a first rotating shaft 201 rotatably installed in the connecting frame 103. A threaded column 202 is fixedly installed on the upper surface of the first rotating shaft 201. A piston column 205 is slidably installed in the threaded column 202. A second rotating shaft 206 is fixedly installed on the upper surface of the piston column 205. The second rotating shaft 206 is rotatably installed in the L-shaped frame 104.

[0030] A guide groove 209 is formed on the outer surface of the threaded column 202. A guide block 211 is slidably installed in the guide groove 209. A push ring 208 is fixedly installed on the outer surface of the guide block 211. In this way, the push ring 208 is sleeved on the outer surface of the threaded column 202. A spring 207 is sleeved on the outer surfaces of the threaded column 202 and the piston column 205. The upper and lower surfaces of the spring 207 are fixedly connected to the lower surface of the second rotating shaft 206 and the upper surface of the push ring 208, respectively.

[0031] A butterfly bolt 203 is threadedly installed on the outer surface of the threaded column 202. In this way, the push ring 208 can be pushed against the upper surface of the butterfly bolt 203 by the elastic pushing force of the spring 207. The extension length of the spring 207 can be adjusted by rotating the butterfly bolt 203.

[0032] A U-shaped frame 212 is fixedly installed on the outer surface of the push ring 208. A limiting rod 210 is rotatably installed in the U-shaped frame 212. In this way, the limiting rod 210 can be inserted into a limiting groove 204. The limiting groove 204 is formed on the outer surface of the butterfly bolt 203. In this way, the rotation of the butterfly bolt 203 can be locked.

[0033] The annular groove 216 is arranged in the U-shaped frame 212, the spring 214 is arranged in the annular groove 216, and the inner annular wall is fixedly connected with the outer surface of the spring 214; the inner annular wall of the spring 214 is fixedly connected with the outer surface of the rotating shaft of the limiting rod 210, so that the spring 214 can exert a torsional force on the limiting rod 210 to make the limiting rod 210 turn inward; the plastic convex ball 215 is fixedly installed at both ends of the limiting rod 210, and the plastic convex ball 215 can be buckled into the groove arranged on the inner side of the extension plate 213; and the extension plate 213 is fixedly installed on the outer surface of the U-shaped frame 212.

[0034] When the front fork of the electric bicycle body 1 is subjected to the vibration force of the wheel transmission, the electric bicycle body 1 can rotate at one end of the rear fork 101 to drive the L-shaped frame 104 to press the piston column 205 to retract into the threaded column 202, and the piston column 205 retracts into the threaded column 202 to press the spring 207 at one end to achieve the purpose of damping; if it is necessary to adjust the softness and hardness of the damping, the staff can turn over the two sets of limiting rods 210 to buckle the plastic convex balls 215 into the extension plate 213 on both sides, and the turned limiting rods 210 can slide out of the limiting grooves 204 arranged on the outer surface of the butterfly bolt 203, thereby releasing the rotational locking of the butterfly bolt 203, and the butterfly bolt 203 can be twisted and rotated on the outer surface of the threaded column 202 to move upward, and the upward rotation can drive the push ring 208 to move upward on the outer surface of the threaded column 202, thereby enabling the push ring 208 to compress the spring 207 between the push ring 208 and the second rotating shaft 206, thereby increasing the hardness of the damping;

[0035] The downward rotation can release the pressing of the push ring 208, and the push ring 208 can be driven by the elastic pushing force of the spring 207 to move downward on the outer surface of the threaded column 202 and press the upper surface of the butterfly bolt 203 rotating downward again, thereby increasing the length of the spring 207 between the push ring 208 and the second rotating shaft 206, thereby increasing the softness of the damping; and the push ring 208 is vertically slid in the guide groove 209 arranged on the outer surface of the threaded column 202 through the guide block 211 fixedly installed on the inner annular wall during the process of being pushed upward or moved downward, and after the softness and hardness of the vibration are adjusted, the staff only needs to turn over the limiting rod 210 again to slide into the limiting groove 204 of the butterfly bolt 203 to lock the rotation of the butterfly bolt 203, and the adjustment of the softness and hardness of the vibration is completed;

[0036] And in the process of torsion of the limiting rod 210, the limiting rod 210 will be twisted together with the torsion spring 214 through the two rotating shafts, so that the torsion spring 214 exerts an inward rotating torsion force on the limiting rod 210, thereby enabling the limiting rod 210 to be kept slidingly inserted in the limiting groove 204 of the butterfly bolt 203 by the torsion of the torsion spring 214.

[0037] According to the above technical scheme, the working steps of the present scheme are summarized and combed: if the front fork of the electric bicycle body 1 is subjected to the vibration force of the wheel transmission during riding, the electric bicycle body 1 can be rotated at one end of the rear fork 101 to drive the L-shaped frame 104 to press the piston column 205 to slide into the threaded column 202, and the piston column 205 will be pressed at one end of the spring 207 during the sliding process to achieve the purpose of damping. If it is necessary to adjust the softness and hardness of the damping, the staff can turn over the two limiting rods 210 to buckle into the extension plate 213 through the two plastic convex balls 215, and the turned over limiting rod 210 will slide out of the limiting groove 204 formed on the outer surface of the butterfly bolt 203, thereby releasing the rotational locking of the butterfly bolt 203. The butterfly bolt 203 can be twisted and rotated on the outer surface of the threaded column 202 to move upward and downward, and the upward rotation will push the push ring 208 to move upward on the outer surface of the threaded column 202, thereby enabling the push ring 208 to compress the spring 207 between the push ring 208 and the second rotating shaft 206, thereby increasing the hardness of the damping. The downward rotation of the butterfly bolt 203 will disengage the push ring 208, and the push ring 208 will be pushed downward on the outer surface of the threaded column 202 by the elastic pushing force of the spring 207 to again press the push ring 208 on the upper surface of the downward rotating butterfly bolt 203, thereby increasing the length of the spring 207 between the push ring 208 and the second rotating shaft 206, thereby increasing the softness of the damping. After adjusting the softness and hardness of the vibration, the staff only needs to turn over the limiting rod 210 again to slide into the limiting groove 204 of the butterfly bolt 203 to lock the rotation of the butterfly bolt 203, and the adjustment of the softness and hardness of the vibration is completed.

[0038] In summary: it can adjust the softness and hardness of the damping, and appropriate damping hardness helps the rider to maintain a stable riding rhythm in different road conditions, avoids the speed from being too fast or too slow due to too soft or too hard damping, makes the riding more smooth, and improves the overall riding efficiency.
