BEST MODE FOR CARRYING OUT THE INVENTION

[0012] The specific technical solutions of the present invention are further described below with reference to the accompanying drawings, so that those skilled in the art can further understand the present invention and do not limit the rights thereof.

Embodiments of the invention [0013] An electric vehicle that folds in opposite directions, including a frame, a front wheel 1, a rear wheel 14, a handlebar 4, and a seat 6, the frame including a front frame body 3 and a rear frame body 13, in front The upper portion of the frame body 3 is provided with a short beam 5 rearwardly. The upper end of the rear frame body 13 is hinged to the end of the short beam 5 via the hinge shaft 17, and the rear frame body 13 is rotated around the hinge shaft 17 to the lower beam 5 to realize the front frame body. 3Folding and folding, the lower end of the rear frame body is provided with a rear fork matched with the rear wheel, the front fork corresponding to the front wheel is provided, the front wheel is mounted on the lower part of the front fork, and the upper part of the front fork passes through the front frame body and the vehicle The battery case is disposed on the front frame, the seat 6 is disposed at the rear of the short beam, the seat includes a seat body and a seat bracket 11, and the rear portion of the short beam 5 is provided with a seat hinge The support I is provided with a seat hinge seat Π on the rear frame body, and the distance D of the seat hinge support seat from the hinge shaft 17 is greater than the distance D _{2 of the} seat hinge support seat I from the hinge axis I, the seat the hinge bracket 11 and the seat support I via a hinge axis between the hinge _Π8 hinge, a guide pin 10 on the seat [pi hinged bearing, provided with a guide pin 10 cooperating with the guide 11 of the seat post The chute 12, the bottom dead center of the guiding chute 12 is a locking point of the horizontal position of the seat body in the frame snagging state, forming a triangular stable support composed of the hinge shaft 17, the hinge shaft 8 and the guide pin shaft 10. After the front frame body 3 and the rear frame body 13 are folded, the guiding pin shaft starts to move along the guiding chute from the bottom dead center of the guiding chute, and the seat bracket is synchronously folded.
