The invention relates to the technical field of bicycles, and discloses a bicycle stall braking device based on the electromagnetic induction principle. The bicycle stall braking device comprises a main body ring and a stall detection device, a fixing plate is fixedly connected in the main body ring, a rotating disc is fixedly connected in the fixing plate, a driving shaft is fixedly connected in the rotating disc, a coil frame is fixedly connected with the back of the driving shaft, the stall detection device comprises a sleeve, a sliding block is slidably connected with the interior of the sleeve, and a solenoid is arranged below the sliding block. According to the invention, when a bicycle stalls, the current leading to the solenoid is increased, the solenoid generates magnetism after being electrified, the magnetism is stronger along with the increase of the current, the sliding block drives a sliding piece to move, the sliding piece drives a limiting column to move when moving, the sliding piece enters a limiting groove in the rotating disc along with the limiting column, and the limiting column enters the limiting groove so that the rotating disc can be braked emergently, the rotating disc and a driving shaft stop moving instantly, and therefore the bicycle is braked emergently.

    本发明涉及自行车技术领域,且公开了一种基于电磁感应原理的自行车失速制动装置,包括主体环与失速检测装置,主体环的内部固定连接有固定板,固定板的内部固定连接有转动盘,转动盘的内部固定连接有驱动轴,驱动轴的后面固定连接有线圈框,失速检测装置包含套筒,套筒的内部滑动连接有滑动块,滑动块下方设置有螺线管。该发明,当自行车发生失速运动时,通向螺线管的电流增大,螺线管通电后产生磁性并且随着电流的增大磁性越强,滑动块带着滑动件移动,滑动件移动时带动限位柱移动,随着限位柱进入到转动盘内的限位槽中,限位柱进入限位槽从而将转动盘进行紧急制动,使得转动盘与驱动轴在瞬间停止运动,从而对自动车进行紧急制动。
