The invention relates to an overheating automatic power-off device for a new energy automobile and relates to the technical field of new energy; the device comprises a shell, a semiconductor chilling plate is fixedly connected to the inner wall of the shell, an electromagnet I is fixedly connected to the inner wall of the shell, a movable groove is formed in the inner wall of the shell, and a spring I is fixedly connected to the inner bottom wall of the movable groove; a movable block is fixedly connected to the top of the spring I, a magnetic block I is fixedly connected to the inner wall of the movable block, and a dielectric plate is fixedly connected to the middle of the movable block. According to the overheating automatic power-off device for the new energy automobile, through cooperative use of the semiconductor chilling plate and the electromagnet, when a charging device is overheated in the charging process, the temperature difference is large, the semiconductor chilling plate generates more electricity, the electromagnet generates large magnetism, and a movable block moves outwards under the magnetic repulsion effect of the electromagnet I and the magnetic block I at the moment; therefore, the voltage passing through the negative plate is greater than the maximum access voltage of the resistor, the charging device is powered off, the charging device is effectively protected, and the safety of the charging device is ensured.

    一种新能源汽车用过热自动断电装置,涉及新能源技术领域,包括壳体,所述壳体的内壁固定连接有半导体制冷片,壳体的内壁固定连接有电磁一,壳体的内壁开设有活动槽,活动槽的内底壁固定连接有弹簧一,弹簧一的顶部固定连接有活动块,活动块的内壁固定连接有磁块一,活动块的中部固定连接有电介质板。该新能源汽车用过热自动断电装置,通过半导体制冷片与电磁体的配合使用,当充电装置充电过热时,这时温差大,半导体制冷片产生的电多,这时电磁体产生的磁性大,这时活动块在电磁一和磁块一的磁性相斥作用下向外侧移动,使通过负极板的电压大于电阻的最大通路电压,使充电装置断电,有效保护充电装置,保证了充电装置的安全。
