Description

Foldable electric scooter

Technical Field

The invention relates to the technical field of electric vehicles, in particular to a foldable electric vehicle.

Background

The foldable electric bicycle is popular with users due to the convenience of use, and the popularization rate is gradually improved.

In the prior art, the front fork of a box-type folding electric vehicle is folded when the box-type folding electric vehicle is folded, and due to the limitation of folding positions, the front fork is basically folded by two schemes, but certain defects exist. The first is short front fork folding, and in the folding state of the folding bicycle, the front wheels can only be accommodated in the front part of the bicycle frame box body, and the rear wheels can only be accommodated in the rear part of the bicycle frame box body due to the occupation of the front part of the bicycle frame box body. This results in the wheel base of folding car between the front and back wheel after expanding too short, and the gesture of riding is not stretched, and its travelling comfort has very big difference with ordinary electric motor car to because the focus leans on the back when riding, should not set up the rear wheel for safety reasons because of the drive wheel. The use of front wheel drive in turn deteriorates the climbing and acceleration capabilities of the electric vehicle. The second is that the long front fork is folded, although the long front fork can fold the front wheel at the rear of the frame box body, the rear wheel is folded at the front of the frame box body, and the problem that the folded wheelbase of the short front fork is too short after the long front fork is unfolded does not exist. However, the longer front fork is used, so that the front fork lifts the whole folding bicycle after being unfolded, the gravity center position of a rider is raised, and the riding safety is not facilitated. The proportion of the front fork with the overlong length and the front wheel with the smaller diameter is not adjusted, and the integral appearance of the foldable electric bicycle is influenced after the foldable electric bicycle is unfolded. Regardless of the scheme used for folding the front fork, the common problems are as follows: the head pipe still occupies the great space in the front of the frame box body when not folded, which results in larger volume and lower folding efficiency after the electric vehicle is folded. And large diameter tires are not suitable.
