ABSTRACT:
An electric vehicle with an innovative folding and positioning structure of the head tube includes a head tube having a bottom connected to the top of a top tube through a movable joint, constituting the swivel part of the head tube. The top of the top tube has a ratchet edge in a circumferential design. The bottom of the head tube is installed with a ratchet block, being pulled up and down to joggle with or detach from the ratchet edge. A transmission shaft, pivoted and located in the slot of the head tube, can be shifted upward and downward. A positioning component, shifting downward through forcing the transmission shaft, enables the joggling between ratchet edge and ratchet block. An elastic component, which pushes upward the transmission shaft when the positioning component is in a release state, and then enables the detachment of ratchet edge from ratchet block.
