  • Patent number: 10232902
    Abstract: A leisure sports scooter comprises a scooter body, wheels and a handlebar. A folding mechanism is arranged between the handlebar and the scooter body. According to the folding mechanism, a hinge-connection section is arranged at the lower end of the handlebar and connected to a connection base through a rotary shaft. The hinge-connection section is a handlebar joint fixed to the lower end of the handlebar or is a lower handlebar section integrated with the handlebar. The rotary shaft is positioned on the connection base. The handlebar can move vertically relative to the rotary shaft. A matched positioning mechanism is arranged between the handlebar and the connection base. When the handlebar moves to a first position, the handlebar and the connection base are positioned, and the positioning mechanism stops the handlebar from rotating. When the handlebar moves to a second position, the handlebar is rotated around the rotary shaft to be folded or unfolded.
