Existing shock-absorbing front forks generally place the shock-absorbing springs on the left and right fork legs respectively, and each fork leg can automatically provide emergency shock absorption. The problem is that the shock absorption extension and retraction actions of the two fork legs may be inconsistent, affecting the balance of the vehicle. Utility Model Content

[0006] The buffer end passes through and is housed in the fork shaft hole, and the limiting nut is located at the end of the buffer end; the shock-absorbing spring is located on the buffer end and between the fork bracket and the limiting nut; the shock-absorbing spring is located on the buffer end and between the fork bracket and the threaded end.

[0007] The shock absorption on both sides is accomplished by the shock-absorbing springs located between the fork axle and the fork bracket. The shock-absorbing extension and retraction movements of the left and right fork legs are consistent, which helps to ensure the balance and stability of the vehicle.

[0008] Preferably, the shock-absorbing fork of the electric scooter also includes a spring stop; the spring stop is located at the buffer end and between the fork bracket and the shock-absorbing spring.

[0009] As a preferred option, the shock-absorbing front fork of the electric scooter also includes a fork foot; the fork foot is fixedly mounted on the fork bracket.

[0010] As a preferred option, the fork feet are also provided with wheel axle mounting holes.

[0011] Preferably, the fork feet and fork bracket are integrally molded structures.

[0012] Preferably, the number of fork legs is two.

[0013] Beneficial technical effects:

[0014] The shock-absorbing front fork of the electric scooter disclosed in this application, by placing the shock-absorbing spring between the front fork bracket and the front fork axle, can ensure that the shock-absorbing extension and retraction of the left and right fork legs are consistent, which is beneficial to improving the vehicle's balance and stability.

[0015] The technical solution and technical effects of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0021] 210 - Buffer end, 220 - Threaded end. Detailed Implementation

[0022] Please see Figures 1 to 2 The electric scooter shock-absorbing front fork disclosed in this application includes a front fork bracket 10, a front fork shaft 20, a shock-absorbing spring 30, a shock-absorbing spring 40, a limit nut 50, and a spring stop 60.

[0023] The fork bracket 10 has a fork axle hole 110 and two fork legs 120, each of which has an axle mounting hole 130. The axle mounting hole 130 is used to mount the wheel axle. The fork axle hole 110 is used to mount the fork axle 20.

[0024] The front fork shaft 20 includes a buffer end 210 and a threaded end 220, and the diameter of the buffer end 210 is smaller than the diameter of the threaded end 220.

[0025] The buffer end 210 passes through and is housed within the fork shaft hole 110, and a limiting nut 50 is disposed at the end of the buffer end 210; the diameter of the limiting nut 50 is larger than the diameter of the fork shaft hole 110. Thus, when the buffer end 210 performs elastic reciprocating movement within the fork shaft hole 110, the limiting nut 50 can limit and block the movement of the buffer end 210.

[0026] A damping spring 40 is disposed on the buffer end 210 and located between the fork support 10 and the limiting nut 50. Specifically, the damping spring 40 has a through hole, and the damping spring 40 is disposed between the fork support 10 and the limiting nut 50 through the cooperation of the through hole and the shaft of the buffer end 210. When the limiting nut 50 moves towards the fork support 10 under the drive of the fork shaft 20, the damping spring 40 can play a buffering role, avoiding rigid contact between the limiting nut 50 and the fork support 10.

[0027] A shock-absorbing spring 40 is disposed on the buffer end 210 and located between the fork support 10 and the threaded end 220. A spring retainer 60 is disposed on the buffer end 210 and located between the fork support 10 and the shock-absorbing spring 30. Specifically, the shock-absorbing spring 40 is sleeved on the fork shaft 20 and compressed between the spring retainer 60 and the threaded end 220. Since the buffer end 210 and the threaded end 220 have a stepped shaft structure, the threaded end 220 and the spring retainer 60 can respectively restrict the shock-absorbing spring 40 from both ends.

[0028] The fork bracket 10 and the fork feet 120 are integrally molded structures.

[0029] Explanation of principles and effects:

[0030] When the impact from the road surface on the wheel is transmitted to the front fork bracket 10, the front fork bracket 10 compresses the shock-absorbing spring 40 through the spring baffle 60. The shock-absorbing spring 40 undergoes elastic deformation to buffer the impact force on the wheel. Since the shock absorption on both sides is accomplished by the shock-absorbing spring 40 located between the front fork axle 20 and the front fork bracket 10, the shock absorption extension and retraction actions of the left and right fork legs are consistent, which helps to ensure the balance and stability of the vehicle.

[0031] The technical solutions and effects of this application have been described in detail above with reference to the accompanying drawings and specific embodiments. It should be noted that those skilled in the art can develop other embodiments based on this. Any simple modifications and equivalent substitutions that do not depart from the innovative concept of this application are covered by this application and fall within the protection scope of this patent.
