The invention discloses an electric vehicle folding frame which comprises a front plate, a first through hole is formed in an inner cavity of the front plate, a first fixing seat is fixedly connected to one side of the front plate, a supporting plate is hinged to one side of the first fixing seat, a pin shaft is arranged between the supporting plate and the first fixing seat for connection, and the supporting plate can rotate around the pin shaft. A threaded hole is formed in an inner cavity of the front plate, and a threaded rod is in threaded connection with the interior of an inner cavity of the threaded hole. According to the electric vehicle, when the electric vehicle needs to be used, a rotary knob is rotated at the moment, a threaded rod is driven to rotate in a threaded hole, and then a moving block and a first rolling wheel are driven to move towards the right side, so that a supporting plate is supported. And when the device needs to be stored, the knob can be rotated reversely, so that the threaded rod and the first roller move leftwards, and at the moment, the supporting plate can be close to the front plate around the pin shaft, so that folding and storage are realized.

    本发明公开了一种电动车折叠车架,包括前板,所述前板的内腔开设有第一通孔,所述前板的一侧固定连接有第一固定座,所述第一固定座的一侧铰接有支撑板,所述支撑板与第一固定座之间设置有销轴连接,支撑板可绕着销轴处进行旋转,从而便于折叠与使用,所述前板的内腔开设有螺纹孔,所述螺纹孔的内腔中螺纹连接有螺纹杆。本发明中,当需要进行电动车的使用时,此时转动旋钮,带动螺纹杆在螺纹孔中进行转动,随即带动移动块与第一滚轮向右侧进行移动,从而对支撑板进行支撑。当需要收纳装置时,可将旋钮反向转动,使得螺纹杆与第一滚轮向左移动,此时可将支撑板绕着销轴处靠近前板,实现折叠与收纳。
