The invention discloses a motor lock control circuit, a charging gun and a new energy automobile, and the motor lock control circuit comprises a power input end which is used for connecting a working power supply; the power output end is used for being connected with a motor lock; the input end and the first controlled end of the switch driving circuit are connected with the power supply input end, and the output end of the switch driving circuit is connected with the power supply output end; the switch driving circuit is used for controlling the power input end to be electrically connected with the power output end when the power input end is powered on so as to drive the motor lock to rotate to the locking position. The power-off trigger circuit is connected with a second controlled end of the switch driving circuit, the power-off trigger circuit is triggered when the motor lock rotates to the locking position, and a power-off signal is output to the switch driving circuit, so that the switch driving circuit controls the power input end to be electrically disconnected with the power output end, and the motor lock is still at the locking position. The electromagnetic lock can solve the problem that an existing electromagnetic lock is prone to being damaged during use.

    本发明公开一种马达锁控制电路、充电枪及新能源汽车,该马达锁控制电路包括:电源输入端,用于接入工作电源;电源输出端,用于接入马达锁;开关驱动电路,开关驱动电路的输入端及第一受控端与电源输入端连接,开关驱动电路的输出端与电源输出端连接;开关驱动电路用于在电源输入端上电时,控制电源输入端与电源输出端电连接,以驱动马达锁转动至上锁位置;断电触发电路,断电触发电路与开关驱动电路的第二受控端连接,断电触发电路被马达锁转动至上锁位置时触发,并输出断电信号至开关驱动电路,以使开关驱动电路控制电源输入端与电源输出端断开电连接,使得马达锁静止于上锁位置。本发明可以解决现有的电磁锁在使用时容易造成损坏的问题。
