The invention relates to the technical field of electric bicycles and discloses an electric bicycle protection device capable of adjusting the height of a seat. The device comprises a shell, wherein a turntable is rotatably connected inside the shell, a sliding block is rotatably connected outside the turntable, a long rod is slidably connected outside the sliding block, and a pushing block is movably connected outside the long rod; a supporting plate is fixedly connected to the exterior of the pushing block, a photosensitive assembly is fixedly connected to the interior of the pushing block, through interaction of all structures of the device, the height of a seat can be adjusted according to the requirements of a user, the rotating speed of a hub can be detected in real time under the action between the box body and the movable block, when the rotating speed of the hub is too high, the hub can be decelerated under the action of the ejector rod and the stop block, so that the effect of decelerating the electric bicycle in time when the rotating speed of the electric bicycle is too high is achieved, and life safety of a user is guaranteed.

    本发明涉及电动自行车的技术领域,且公开了一种可以调节座椅高度的电动自行车保护装置,包括外壳,所述外壳的内部转动连接有转盘,转盘的外部转动连接有滑块,滑块的外部滑动连接有长杆,长杆的外部活动连接有推动块,推动块的外部固定连接有支撑板,推动块的内部固定连接有光敏组件,通过本装置所有结构之间的相互作用下,可以使得根据使用者的需求对座椅高度进行调节,并且可以实时在箱体与活动块之间的作用下对轮毂的转速进行检测,当在轮毂转动速度过快时,在顶杆与阻挡块之间的作用下可以对轮毂进行减速,从而达到了可以在电动自行车转动速度过快时及时的对其进行减速的效果,保证了使用者的生命安全。
