Abstract

A novel foldable scooter, comprising a scooter body folding mechanism and a handle folding mechanism. The scooter body folding mechanism is used to fold a column (11) towards a board by means of a second eccentric wheel assembly; the handle folding mechanism is used to fold a handle (10) towards the ground by means of a first eccentric wheel assembly; and two sets of eccentric wheel assemblies work in conjunction with each other, so that the handle (10) of the scooter can be turned over downwards, and a scooter body is folded, thus greatly reducing the storage space. Moreover, the folding of the scooter body can be completed only by one press, one lift, and one rotation. After the whole scooter is folded, a folding handle (14) is completely consistent with the direction of the scooter body; and after the folding, lock and fixation can be completed only by restoring the folding handle (14); the whole operation is simple and convenient, and the scooter is suitable for all age groups. The operation is simple, and turn over and restoration can be implemented only in a few simple steps.
