The invention discloses an electric control rotating arm locking device and an automatic folding bicycle, the electric control rotating arm locking device comprises a first rotating arm and a second rotating arm which are rotatably connected, the first rotating arm is provided with a first locking mechanism, and the first locking mechanism comprises a first rotating piece and a second rotating piece; the second rotating arm is fixedly provided with a third rotating piece; the second rotating arm is provided with a second locking mechanism, and the second locking mechanism is matched with the second rotating piece to lock or unlock the first rotating arm and the second rotating arm. The first rotating piece arranged in the first rotating arm is matched with a third rotating piece arranged in the second rotating arm to achieve butt joint of ports of the first rotating arm and the second rotating arm, and then the second rotating piece of the first rotating arm is matched with the second locking mechanism in the second rotating arm to execute locking action. The locking process of the rotating arms is divided into structural execution corresponding to the two steps of butt joint and locking, and the locking stability and the unlocking flexibility between the locking arms can be guaranteed.

    本发明公开了一种电控旋转臂锁紧装置和自动折叠车,该电控旋转臂锁紧装置包括转动连接的第一旋转臂和第二旋转臂,第一旋转臂设置有第一锁紧机构,第一锁紧机构包括第一转动件和第二转动件;第二旋转臂固定设置有第三转动件;第二旋转臂设有第二锁紧机构,第二锁紧机构与第二转动件配合,锁紧或解锁第一旋转臂与第二旋转臂。本发明利用第一旋转臂中设置的第一转动件与第二旋转臂中设置的第三转动件配合实现第一旋转臂和第二旋转臂的端口对接,再利用第一旋转臂的第二转动件与第二旋转臂中的第二锁紧机构配合执行锁紧动作,通过将旋转臂锁紧过程划分为对接和锁紧两个步骤对应的结构执行,能够保证锁紧臂与锁紧臂之间锁紧的稳定性和解锁的灵活性。
