The invention relates to the technical field of electric bicycles, and discloses an electric bicycle capable of preventing electric overload damage, which comprises a fixed shaft, the outer side of the fixed shaft is movably connected with a turntable, the inner wall of the turntable is provided with a chute, and the inner wall of the turntable is provided with a groove close to the outer side of the chute. A slide rheostat is fixedly connected to the inner wall, close to the inner side of the sliding groove, of the rotating disc, and an electromagnet is fixedly connected to the inner wall of the rotating disc. According to the electric bicycle capable of preventing the electric overload damage, through the characteristics of the electroactive polymer, under the action of stimulation, the size of the electroactive polymer can be reduced, and the electric contacts are electrically connected with the contact points, so that when a motor of the electric bicycle cannot drive a rotating wheel to rotate, the motor is prevented from being in an overload working state; a large amount of heat is prevented from being generated in the motor, damage to the motor is avoided, the service life of the motor is prolonged, and the service life of the electric bicycle is prolonged.

    本发明涉及电动自行车技术领域,且公开了一种防止电力过载损伤的电动自行车,包括固定轴,所述固定轴的外侧活动连接有转盘,所述转盘的内壁开设有滑槽,所述转盘的内壁且靠近滑槽的外侧开设有凹槽,所述转盘的内壁且靠近滑槽的内侧固定连接有滑动变阻器,所述转盘的内壁固定连接有电磁铁。该防止电力过载损伤的电动自行车,通过电活性聚合物的特性,在刺激的作用下,电活性聚合物体积会收缩,电触点与接触点的电性连接,实现了当电动自行车的电机无法驱动转轮的转动时,避免电机处于超负荷的工作状态,防止电机内部产生大量的热量,避免造成电机的损伤,提高了电机的使用寿命,提高降低了电动自行车的使用寿命。
