The embodiment of the application provides a lock tongue driving mechanism and a lock, and please refer to fig. 1 to 10 together.

As shown in fig. 5 and 6, the deadbolt driving mechanism includes a drive motor 510, an electronic lock cylinder 520, a rotary member 530, and a driver 540. The driving motor 510 and the electronic lock cylinder 520 are connected to the rotating member 530 to drive the rotating member 530 to rotate. The rotating member 530 is in driving connection with the driving member 540, and the driving member 540 is adapted to be connected with the tongue 300. The driving member 540 is driven to linearly move when the rotating member 530 rotates.

When the lock cannot supply power to the driving motor 510, an unlocking person only needs to insert a key with a battery into the electronic lock cylinder 520 to rotate the key, the key drives the rotating member 530 to rotate through the electronic lock cylinder 520, and the rotating member 530 drives the driving member 540 to linearly move when rotating, so that the lock tongue 300 returns into the lock, and unlocking is finally realized. The lock tongue actuating mechanism provided by the embodiment of the application still can open the lock under the condition that the power cannot be supplied to the driving motor 510 in the lock.

Specifically, the driving motor 510 and the rotating member 530 may be directly connected, that is, an output shaft of the driving motor 510 is connected to the rotating member 530, and the output shaft of the driving motor 510 directly drives the rotating member 530 to rotate; the drive motor 510 may also be indirectly coupled to the drive assembly. 5-7, the deadbolt drive mechanism also includes a transmission assembly, wherein the transmission assembly includes a motor gear 550 and an incomplete gear 560; the motor gear 550 is mounted to a rotation shaft of the driving motor 510; the incomplete gear 560 is coaxially coupled to an outer side surface of the rotating member 530 and is engaged with the motor gear 550.

When the driving motor 510 is powered and the bolt 300 is required to extend or retract, the output shaft of the driving motor 510 rotates, and the motor gear 550 mounted on the output shaft of the driving motor 510 drives the incomplete gear 560 to rotate, so that the rotating member 530 drives the driving member 540 to move, and the bolt 300 connected with the driving member 540 extends or retracts from the first housing 100 into the first housing 100.

The transmission assembly for transmitting the power of the driving motor 510 to the rotating member 530 is not limited to the specific structure shown in fig. 5 to 7, and may be other structures. For example, the transmission assembly includes a first sprocket mounted to the driving motor 510, a second sprocket mounted to an outer side of the rotating member 530, and a chain mounted to the first sprocket and the second sprocket.

Referring to fig. 5 and 8, the driver 540 has a first blocking surface 541, and the incomplete gear 560 is provided with a second blocking surface 561. When the rotating member 530 drives the lock tongue 300 to retract to the unlocking position through the driving member 540, the first blocking surface 541 abuts against the second blocking surface 561, so that the lock structure is prevented from being damaged due to the condition that the lock tongue 300 is retracted beyond the unlocking position.

A specific structure for achieving a driving connection between the driving member 540 and the rotating member 530 according to an embodiment of the present application is shown in fig. 5, and is described below. The driving member 540 is provided with a notch 542 facing the rotating member 530; the rotating member 530 is provided with a driving lever 531, and a free end of the driving lever 531 extends into the notch 542. When the rotating member 530 rotates, the driving handle 531 rotates around the central axis of the rotating member 530 in the slot 542, and the driving handle 531 applies an external force to the inner wall of the slot 542 to toggle the driving member 540, so that the driving member 540 drives the latch bolt 300 to extend or retract.

The specific structure of the rotating member 530 in the embodiment of the present application is shown in fig. 8 and 9. The rotating member 530 is cylindrical, and the inner wall of the rotating member 530 is provided with a force receiving projection 532. The output end of the electronic lock cylinder 520 abuts against the stress protrusion 532, and the right end of the electronic lock cylinder 520 is the output end, taking the orientation of the electronic lock cylinder 520 shown in fig. 10 as an example. When a correct key is inserted into the electronic lock cylinder 520, the key supplies power to the electronic lock cylinder 520, so that the output end of the electronic lock cylinder 520 can rotate along with the key. When the output end of the electronic lock core 520 rotates, an external force is applied to the stress protrusion 532 on the inner wall of the rotating member 530, so that the rotating member 530 rotates.

The tongue driving mechanism further comprises an inner unlocking member 570, wherein the output end of the inner unlocking member 570 is abutted against the stress protrusion 532, and the inner unlocking member 570 is positioned on the inner side of the lockset. A person located inside the door where the lock is installed rotates the inner unlocking member 570 through a handle connected to the inner unlocking member 570, and thus drives the rotating member 530 to rotate, so that the latch bolt 300 is retracted into the lock.

The deadbolt drive mechanism also includes a slide assembly having two opposing slide portions disposed within the driver 540 and the first housing 100, respectively. Illustratively, the sliding assembly includes a first slider 543 disposed in the driving member 540 shown in fig. 5 and a first slide rail 110 disposed in the first housing 100 shown in fig. 4, wherein the first slider 543 is disposed in the first slide rail 110 and can slide in the first slide rail 110 when the latch driving mechanism is mounted in the first housing 100; and/or the sliding assembly includes the second slideway 544 shown in fig. 5 disposed in the driver 540 and the second slider 120 shown in fig. 4 disposed in the first housing 100, the second slider 120 being disposed in the second slideway 544 and being capable of sliding in the first slideway 110 when the deadbolt driving mechanism is mounted to the first housing 100.

As shown in fig. 2 to 4, the present embodiment also provides a lock including the first housing 100, the second housing 200, the latch bolt 300, the control circuit board 400, and the latch bolt driving mechanism described above. The bolt 300, the control circuit board 400 and the bolt driving mechanism are all arranged on the first shell 100, the bolt 300 is connected with the driving piece 540, and the driving motor 510 is electrically connected with the control circuit board 400; the second housing 200 is provided with a receiving hole into which the latch bolt 300 is inserted.

Referring to fig. 2, the latch further includes a charging interface 600. The charging interface 600 is mounted to the first housing 100 and is electrically connected to the control circuit board 400. When the lock is powered down, an operator may power the lock through the charging interface 600. Specifically, the charging interface 600 may be a USB interface.
