The invention relates to the technical field of electric vehicles, and discloses an electric vehicle stall protection device based on the electromagnetic induction principle. The electric vehicle stall protection device based on the electromagnetic induction principle comprises a shell and a motor. The interior of the shell is movably connected with a first spring, the exterior of the first springis movably connected with a sliding rod, the interior of the shell is movably connected with an N pole, the interior of the shell is movably connected with an S pole, and the interior of the shell isfixedly connected with an electromagnet. Under the interaction of the shell, the motor, the first spring, the sliding rod, the N pole, the S pole, the electromagnet, a rotating shaft, a movable block, a second spring and a rotating block, when the motor stalls and the rotating speed of the motor is too high, an electromagnetic induction device can be triggered, then a speed reduction device is started later, triggering is more sensitive and the device is more suitable for the situation in which the rotating speed is too high, a driver can be reminded through an alarm, an early warning effectcan be achieved while the speed is reduced, and the driving safety of the driver is guaranteed.

    本发明涉及电动车的技术领域,且公开了一种基于电磁感应原理的电动车失速保护装置,包括外壳和电机,所述外壳的内部活动连接有弹簧一,弹簧一的外部活动连接有滑杆,外壳的内部活动连接有N极,外壳的内部活动连接有S极,外壳的内部固定连接有电磁铁;通过外壳、电机、弹簧一、滑杆、N极、S极、电磁铁、转轴、活动块、弹簧二、转块之间的相互作用下,可以使得电机发生失速造成电机转动速度过快时,可以触发电磁感应装置,进而使得之后的降速装置得以启动,这样的触发也会更为灵敏,更适用于转速过快时的情况发生,并且也可以通过警报器来提醒驾驶人,这样在降速的同时也可以起到预警的作用,保证了驾驶人的行驶安全。
