Abstract

A V-shaped folding electric vehicle comprises: a vehicle frame; a front wheel (1); a rear wheel (8); a handle (5); and a seat (6). The vehicle frame and the handle (5) are made of a carbon fiber composite material. The vehicle frame comprises a front frame body (3) and a rear frame body (7) which are hinged to form a V shape. A battery container is disposed at the front frame body (3). A seat supporting rod is hinged to the rear frame body (7) under a hinge shaft (4). A middle portion of the seat supporting rod and the rear frame body (7) are hinged by means of a pin roll. A position-limiting guide slot (10) for limiting an opening angle of the vehicle frame is arranged axially at a front portion of the seat supporting rod. The front frame body (3) is provided with a guide post corresponding to the position-limiting guide slot (10). The seat (6) is disposed at a rear portion of the seat supporting rod. When the electric vehicle is to be folded, the guide post moves along the position-limiting guide slot (10) to drive the seat supporting rod to rotate about the pin roll, thereby realizing simultaneous folding of the seat (6).
