Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying 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 work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: an electric vehicle front fork with high safety performance comprises a front fork rod 1, a connecting cylinder 2, a wheel fixing rod 3, a corrugated rubber sleeve 4, a spring 5, a connecting rod 6, a movable groove 7, a fixing frame 8, a pulley 9 and a rubber pad 10, wherein two vertical supporting rods of the front fork rod 1 are inserted in the connecting cylinder 2, the wheel fixing rod 3 is specified by welding the lower end of the connecting cylinder 2, the connecting rod 6 is connected between the two vertical supporting rods of the front fork rod 1, the connecting rod 6 is in a semicircular structure, the arrangement of the connecting rod 6 ensures the consistency of the insertion depth of the two vertical supporting rods of the front fork rod 1 in the connecting cylinder 2, the damping effect of an electric vehicle is more balanced, the driving effect is more stable, the corrugated rubber sleeve 4 is arranged on the periphery of one section of the two vertical supporting rods of the front fork rod 1, the two ends of the corrugated rubber sleeve 4 are respectively glued and connected with the supporting rods of the front fork rod 1 and the top end of the connecting cylinder 2, the corrugated rubber sleeve, the inner space of the connecting cylinder 2 is sealed and protected to a certain extent, so that rainwater and foreign matters are prevented from entering the connecting cylinder 2 to cause adverse effects, the inner diameter of the connecting cylinder 2 is equal to the outer diameters of two vertical supporting rods of the front fork rod 1, the arrangement ensures that the moving track of the front fork rod 1 is limited, the front fork rod 1 keeps a vertical moving track, the deviation of a reset position in the moving process of the front fork rod 1 is avoided, the front fork rod 1 is arranged to be of an inverted Y-shaped structure, parallel grooves are arranged at the lower ends of the two vertical supporting rods of the front fork rod 1 and the bottom end of the inner wall of the connecting cylinder 2, a connected spring 5 is arranged in the wall of the groove between the two parallel grooves, a connected fixing frame 8 is arranged at the lower ends of the two vertical supporting rods of the front fork rod 1, the fixing frame 8 is arranged to be of an L-shaped structure, the cross rod part of the fixing frame 8 is arranged in movable grooves 7 arranged at two sides of the inner, cushion 10 can play certain shock attenuation guard action, avoids mount 8's horizontal pole to be damaged by the collision at the activity in-process, alternates through the pivot on mount 8's the horizontal pole and rotates and be connected with pulley 9, and pulley 9 contacts with the recess wall of activity groove 7 mutually, and pulley 9 rotates along with mount 8's activity and the 7 wall friction of activity groove, has reduced the resistance of mount 8 activity in-process, lets mount 8's activity simple operation smooth and easy.
