The invention relates to the technical field of electric vehicle chargers, and discloses an electric vehicle charger with a self-protection function. The electric vehicle charger comprises a shell, anelectromagnet is fixedly connected to the inner wall of the shell, a spring is fixedly connected to the inner wall of the shell and close to the top of the electromagnet, and a sliding block is fixedly connected to the top of the spring. A magnetic block is fixedly connected to the inner wall of the sliding block, a dielectric plate is fixedly connected to the top of the sliding block, and a positive plate is fixedly connected to the position, close to the outer side of the dielectric plate, of the inner wall of the shell. According to the electric vehicle charger with a self-protection function, the rotating frequency of a cooling fan is changed by changing the relative area of the positive plate and the negative plate, so that the temperature of the electric vehicle charger is reduced,heat generated by the charger is dissipated in time, short circuit of a circuit is avoided, fire disasters are prevented, economic losses are avoided, and the safety coefficient is increased; meanwhile, the service life of the electric vehicle charger is prolonged, and resources are saved.

    本发明涉及电动汽车充电器技术领域,且公开了一种具有自我保护功能的电动汽车充电器,包括壳体,所述壳体的内壁固定连接有电磁铁,所述壳体的内壁且靠近电磁铁的顶部固定连接有弹簧,所述弹簧的顶部固定连接有滑块,所述滑块的内壁固定连接有磁块,所述滑块的顶部固定连接有电介质板,所述壳体的内壁且靠近电介质板的外侧固定连接有正极板。该具有自我保护功能的电动汽车充电器,通过正极板与负极板相对面积的改变,实现了改变散热扇的转动频率,从而降低电动汽车充电器的温度,让充电器产生的热量及时散去,避免电路短路,防止火灾的发生,避免经济损失,提高安全系数,同时提高电动汽车充电器的使用寿命,达到节约资源。
