The invention discloses an electronic lock structure of a charging gun and the charging gun. The electronic lock structure of the charging gun comprises an electronic lock; the H-bridge circuit is used for driving the motor to rotate forwards to enable the electronic lock to work in a locking mode, driving the motor to rotate reversely to enable the electronic lock to work in an unlocking mode, and discharging the reverse electromotive force generated when the motor is powered off to enable the electronic lock to work in a discharging mode; the sampling module is used for collecting reverse electromotive force generated when the motor is powered off; and the MCU is used for controlling the working mode of the electronic lock and adjusting the duration of the electronic lock working in the discharge mode according to the back electromotive force fed back by the sampling module. The purposes of unlocking, locking and reverse electromotive force discharging of the electronic lock are achieved ...
