Description

Technical Field

[0001] The utility model relates to the technical field of scooters, in particular to a foldable scooter. Background Art

[0002] An electric scooter is a vehicle that uses an onboard battery to provide power to drive a joystick to control the motor output, which then drives the rear wheel through a transmission mechanism. The rear wheel then drives the front wheel to rotate synchronously to achieve travel. Although its speed is low and the riding distance is limited, it can improve people's travel efficiency and is green and environmentally friendly. Electric scooters include various forms of short-distance transportation such as bicycles and scooters, and there is a huge market demand for them.

[0003] In order to solve the problem that the scooter needs to occupy a large storage space due to its large size, people have invented a foldable scooter. Most of the existing scooters have foldable handlebars and seats to reduce the occupied volume of the scooter. Take the foldable electric scooter disclosed in the prior art 202120499916.1 as an example. The scooter includes a frame assembly, a handle assembly and a seat assembly. The above scheme reduces the volume occupied by the entire electric scooter by folding the handle assembly and the seat assembly. However, the folding of the frame cannot be achieved, and the space occupied in the horizontal direction cannot be reduced, which is not conducive to storage and transportation.
