By adopting the technical scheme, when the door is in the locked state, as the corresponding lock hole is arranged at the door frame corresponding to the lock tongue, the corresponding control tongue is not provided with the lock hole, at the moment, the lock tongue is in the extending state, and the control tongue is in the retracting state due to the action of the door frame, namely, the lock tongue extends out and is clamped in the door frame, and the door cannot be opened. At this moment, the motor is not electrified, the spring bolt rod return spring is in a non-compression state, the transmission rod return spring is in a compression state, the movable shaft spring of the motor transmission mechanism is in a non-compression state, the upper end of the movable shaft is matched and abutted against the small diameter part of the round column of the transmission clutch control mechanism, the clutch pin is positioned at the upper end of the movable bar hole and is inserted into the U-shaped groove of the clutch driven gear, the driving gear is in a state capable of driving the clutch driving gear, the rack is meshed with the clutch driven gear, the first end of the transmission shifting fork is rotatably and movably connected to the lock shell through the shifting fork pin shaft, the second end of the transmission shifting fork is matched and connected with the spring bolt control end, and the rack is matched and connected with the transmission shifting fork.
When the door needs to be opened, a power signal for starting the motor is firstly needed through a power signal control mechanism (a switch can be used for switching on the power or the signal is used for starting and switching on the power), after the motor is electrified, the driving gear connected to an output shaft of the motor is driven, the clutch driving gear is driven to rotate, meanwhile, the rack is driven to move rightwards, the rack drives the transmission shifting fork to rotate anticlockwise, so that the whole lock tongue rod is driven to move rightwards, in the process, the return spring of the lock tongue rod is gradually compressed until the lock tongue is completely separated from the door frame, and the door can be opened at the moment when the lock tongue is in a retracted state; of course, because the position sensor can be adopted to give position signals in the design, when the lock tongue is in a certain fixed position in the retracted state, the motor immediately stops running, and the left tension of the return spring of the lock tongue rod can also be reasonably designed to ensure that the tension and the rack run rightwards to form dynamic balance, so that the lock tongue has distance-limited rightwards movement.
When the door is opened, the control tongue naturally stretches out leftwards under the condition that the door frame is not restrained by the return spring of the transmission rod to drive the transmission rod of the control tongue to move leftwards, the upper end of the movable shaft gradually changes from being matched and propped against the small diameter part of the round column of the transmission clutch control mechanism to be matched and propped against the large diameter part of the round column of the transmission clutch control mechanism, meanwhile, the movable shaft drives the clutch pin to move downwards to compress the movable shaft spring, the movable shaft spring is in a compressed state at the moment, the clutch pin is separated from the U-shaped groove, the driving gear is separated from the clutch driven gear of the clutch driving gear, no power is input, and the clutch driving gear is radially fixed on the shaft sleeve in an empty sleeve; under the action of the spring bolt rod return spring, the spring bolt is also in a leftward extending state.
