Description
Technical Field
[0001] The utility model relates to the technical field of electric scooters, in particular to an improved front fork of an electric scooter. Background Technique
[0002] The scooter is a new product form of skateboarding after the traditional skateboard, and has been deeply loved by teenagers in recent years. The main structure of the common scooter in the prior art is that wheels are pivotally arranged at the front and rear ends of the vehicle frame, and a pedal is erected in the middle section. When operating, one foot steps on the pedal, and the other foot steps on the ground to push. When the scooter has the inertial power to slide forward, both feet are retracted and stepped on the pedal. When the speed of the scooter slows down to about to stop, the above actions are repeated to make the scooter have the function of labor-saving movement and also have the effects of sports and leisure. Among them, in the steering design of the scooter, a riser is pivotally arranged at the front end of the vehicle frame. The upper end of the riser is provided with a handle, and the lower end is connected with a front fork. The front wheel is pivotally connected to the front fork, and the front wheel can be steered by controlling the handle.
[0003] At present, due to the relatively simple structure of the existing scooter front fork, its own functions are not perfect enough to meet the reliability test of tension, impact, fatigue and ultimate torque, which is not conducive to ensuring the reliability of the whole vehicle.
