Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a retractable electric scooter. Background Technology

[0002] Scooters generally consist of a pedal, handlebar assembly, and wheel assembly. Currently, all scooter pedals are a single piece with no adjustable length. Because space needs to be provided for children's feet to step on, the pedal length is generally over 50cm, which makes them take up a lot of space and inconvenient to store or carry. Patent No. CN201922294474.2 discloses a scooter, including a first support rod, a first pedal disposed on the upper side of the first support rod, a second support rod, a second pedal disposed on the upper side of the second support rod, and a locking mechanism. The first pedal and the second pedal form a first upper surface and a second upper surface, respectively. The second pedal unit includes a second support rod and a second pedal disposed on the upper side of the second support rod. The scooter has a first state and a second state. When the scooter is in the first state, the first support rod and the second support rod are open to each other, and the first upper surface and the second upper surface are at least partially offset in the front-rear direction of the scooter, so that the pedal has a first stepping surface. When the scooter is in the second state, the first support rod and the second support rod are close to each other, and the first upper surface and the second upper surface are at least partially overlapped in the front-rear direction of the scooter, so that the pedal has a second stepping surface. The length of the first stepping surface in the front-rear direction is greater than that of the second stepping surface. Because the lock hole position is fixed, the positions of the first and second pedals are fixed after adjustment and locking, making it impossible to freely adjust the overall length of the scooter's pedals, resulting in poor practicality. Therefore, this utility model proposes a retractable electric scooter. Utility Model Content

[0003] The main purpose of this utility model is to provide a retractable electric scooter, wherein the DC motor drives the lead screw to rotate, thereby driving the connecting block to slide along the axis of the lead screw, thus freely adjusting the extension length of the movable pedal, making it more practical.
