Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, the front shock absorber of the electric scooter is composed of a steering gear assembly 100, a front left shock absorber assembly 200 and a front right shock absorber assembly 300; the steering gear component 100 consists of a column and a yoke plate, and the column of the steering gear component 100 is connected with a head tube and a handle of the frame of the electric scooter so as to realize the connection and steering of the front fork and the frame.

Referring to fig. 2, the front left damper assembly and the front right damper assembly of the electric scooter are composed of a bolt assembly 1, a handle rod assembly 2, a dust seal 3, a snap spring 4, an oil seal 5, a long spring 6, a piston rod 7, a piston ring, a buffer spring 8, a bottom cylinder 10, a sealing washer 11, a screw 12 and the like.

The working principle is as follows: when the front shock absorber is compressed by road impact, the long spring 6 is compressed to generate reaction force, meanwhile, the volume below the working cylinder is reduced, most of oil flows to the upper part of the working cylinder through the compression damping hole on the piston rod 7 and the inner hole of the front damping rod, and most of oil flows to the cavity where the buffer spring 8 is located through the gap between the toothed ring and the toothed ring seat and the restoration damping hole, because the compression damping force generated by the compression damping hole with larger aperture and the gap between the toothed ring and the toothed ring seat (when the front shock absorber is compressed, the oil pushes up the toothed ring and the gap between the upper end toothed structure of the toothed ring and the end surface of the toothed ring seat is larger), if the reaction force generated by the compression of the spring cannot prevent the front shock absorber from continuously pressing down and is compressed to the compression damping hole on the piston rod inner toothed ring cover 7, the oil in the lower cavity can only flow to the buffer spring cavity through the gap between the toothed ring and the toothed ring seat to generate larger compression damping force, meanwhile, because the pressure in the working cylinder is gradually increased (the internal air is also compressed to generate internal pressure due to the compression of the shock absorber), the continuous pressing of the shock absorber is prevented by the large compression damping force, the gradually increased internal pressure and the gradually increased compression reaction force of the shock absorbing spring. When the front shock absorber rebounds upwards under the action of the reaction force generated after the spring is compressed, oil above the working cylinder flows to the lower side of the working cylinder through the inner hole of the front damping rod and the compression damping hole; the buffer spring cavity is smaller along with the reduction of the volume, except that a small part of oil flows to the lower part of the working cylinder through a small gap between an inner hole of the toothed ring and the outer circle of the front damping rod, most of the oil needs to flow to the lower part of the working cylinder through a small restoring damping hole to generate a large restoring damping force, and if the shock absorber continuously rebounds until the toothed ring seals the restoring damping hole, the oil in the buffer spring cavity 8 only can flow out from a fit gap between the toothed ring and the piston rod 7 at the moment, so that a larger restoring damping force is generated; if the shock absorber continues to rebound, the buffer spring is compressed and generates a reaction force, and the rebound force and the reaction force of the buffer spring 8 are combined to prevent the shock absorber from continuously rebounding.

Therefore, the impact of the road surface to the front wheel is relieved by the compression reaction force of the long spring 6 in the hydraulic front shock absorber, and the shock of rebound after shock absorption of the spring 6 and the impact from the road surface are restrained by the restoring damping force of the damper, so that the shock absorption effect on the front wheel of the electric scooter is achieved. And the hydraulic buffer and the internal pressure are used for avoiding the compression bottom contact of the hydraulic front shock absorber and the compression reaction force and the recovery resistance of the buffer spring so as to avoid the ultimate stretching of the hydraulic front shock absorber.
