When the main bolt 400 extends out of the main bolt hole 113, the first position detecting hook 401 triggers the first position switch 1302, and at this time, the PCB 1300 determines that the main bolt 400 has extended out, and the driving assembly 900 stops driving the gear set 1000; when the main bolt 400 is retracted into the main bolt hole 113, the first position detecting hook 401 triggers the second position switch 1303, and at this time, the PCB 1300 determines that the main bolt 400 is retracted into position, and the driving assembly 900 stops driving the gear set 1000.
The PCB 1300 is further provided with a third position switch 1304, and the second gear 1020 is provided with a second position detecting hook 1022 for triggering the third position switch 1304.
In the locking process, after the locking is in place, after a certain delay, the driving assembly 900 drives the second gear 1020 to rotate anticlockwise, and when the second position detection hook 1022 on the second gear 1020 triggers the third position switch 1304, the PCB 1300 judges that the second gear 1020 is reset, and the driving assembly 900 stops driving the second gear 1020 to act; in the unlocking process, after unlocking, after a certain delay, the driving assembly 900 drives the second gear 1020 to rotate clockwise, when the second position detection hook 1022 on the second gear 1020 triggers the third position switch 1304, the PCB 1300 judges that the second gear 1020 is reset, and the driving assembly 900 stops driving the second gear 1020 to act; whether the second gear 1020 is turned by a certain angle after the locking or unlocking, the driving assembly 900 drives the second gear 1020 to return to the initial position, so that the damage to parts in the automatic lock body caused by manually lifting or pressing down the handle after the locking or unlocking can be avoided.
As shown in fig. 1 and 2, the first transmission assembly 1100 includes a fourth gear 1110, a first transmission member 1120, and a second torsion spring 1130, and the fourth gear 1110 and the first transmission member 1120 are rotatably installed in the accommodating chamber 110; the upper end of the first transmission member 1120 is provided with a first hook 1121 for pulling the barb 501, the lower end is provided with a second hook 1122, the fourth gear 1110 is meshed with the first gear 1010, and the fourth gear 1110 is provided with a third hook 1111 for pulling the second hook 1122; the first transmission member 1120 is further provided with a transmission rib 1123; the second torsion spring 1130 is installed in the accommodating cavity 110, one pin of the second torsion spring 1130 is pressed above the driving rib 1123, and the accommodating cavity 110 is provided with a stopper 116 at the rear end above the first driving member 1120.
In the unlocking process, the gear set 1000 drives the fourth gear 1110 to rotate clockwise, at this time, the third hook 1111 on the fourth gear 1110 toggles the second hook 1122, so that the first transmission member 1120 counter-clockwise rotates against the elastic force of the second torsion spring 1130, and then the first hook 1121 toggles the barb 501, so that the front end of the latch positioning member 500 descends, at this time, the movement of the latch 200 is not limited by the latch positioning member 500, and can freely stretch and retract in the latch hole 111.
After the door is opened, i.e. the detecting tongue 300 pops out, after the protruding block 301 is blocked into the bayonet 502 again, after a certain time delay, the second gear 1020 is reset, at this time, the pin of the second torsion spring 1130 applies a pressing force to the transmission convex rib 1123, so that the first transmission member 1120 rotates clockwise by a certain angle, the rear end of the first transmission member 1120 abuts against the limiting block 116, at this time, the first clamping hook 1121 and the barb 501 are in a separated state, at the same time, the second clamping hook 1122 can toggle the third clamping hook 1111 to drive the fourth gear 1110 to rotate anticlockwise by a certain angle, the fourth gear 1110 drives the first gear 1010 to rotate clockwise by a certain angle, and because the second gear 1020 is reset, the first gear 1010 can not drive the second gear 1020 to rotate, so that the driving component 900 is not damaged, and in addition, because the third gear 1030 is provided with the second notch 1031, the first gear 1010 can not drive the third gear 1030 to rotate, so that the second transmission component 1200 can not rotate, the main bolt 400 can not act, and internal parts can not be damaged.
As shown in fig. 1 and 2, a push rod portion 410 is provided at the rear end of the main latch 400, and a latch notch 411 is provided at the lower end of the push rod portion 410; the second transmission assembly 1200 includes a fifth gear 1210, a sixth gear 1220, and a third torsion spring 1230; the fifth gear 1210 is meshed with the third gear 1030, and the fifth gear 1210 is meshed with the sixth gear 1220; a shift lever 1221 is provided on the sixth gear 1220 and cooperates with the lock tongue notch 411, and when the sixth gear 1220 rotates, the shift lever 1221 shifts the main lock tongue 400; one leg of the third torsion spring 1230 hooks the lever 1221.
In the locking process, the gear set 1000 drives the fifth gear 1210 to rotate anticlockwise, then the fifth gear 1210 drives the sixth gear 1220 to rotate clockwise, and the shift lever 1221 shifts the lock tongue notch 411 at this time, so that the main lock tongue 400 extends out of the main lock tongue hole 113, and the locking is completed; after the main lock tongue 400 extends out of the main lock tongue hole 113, the deflector rod 1221 needs to overcome the elastic force of the third torsion spring 1230 to act backward, and the third torsion spring 1230 is provided to enable the main lock tongue 400 to keep the extending state after locking, even if the main lock tongue 400 is retracted for a small period after being stressed, the main lock tongue 400 extends out of the main lock tongue hole 113 again under the elastic force of the third torsion spring 1230, so that the safety is higher.
As shown in fig. 1 and 2, the first gear 1010, the third gear 1030, the fourth gear 1110, the fifth gear 1210, and the sixth gear 1220 are all sector gears.
Because first gear 1010, third gear 1030, fourth gear 1110, fifth gear 1210 and fourth gear 1110 are when rotating, only partial tooth plays the transmission effect, and all other teeth do not play any role, so first gear 1010, third gear 1030, fourth gear 1110, fifth gear 1210 and fourth gear 1110 adopt the sector teeth, the processing difficulty of parts is reduced under the premise that unlocking and locking actions of the automatic lock body can be completely realized, the production cost is greatly saved, and meanwhile, the volumes of first gear 1010, third gear 1030, fourth gear 1110, fifth gear 1210 and fourth gear 1110 can be reduced, the volume of the automatic lock body is further reduced, and the internal structure of the automatic lock body is more compact.
The technical principle of the present invention is described above in connection with the specific embodiments. The description is made for the purpose of illustrating the general principles of the invention and should not be taken in any way as limiting the scope of the invention. Other embodiments of the invention will be apparent to those skilled in the art from consideration of this specification without undue burden.
