The following describes the latch bolt driving mechanism according to an embodiment of the present invention in detail with reference to the drawings.

Referring to fig. 1 to 4 and 5 to 10, a latch driving mechanism according to an embodiment of the present invention includes a latch 20, a pivot shaft 30, a rotating arm 40, an operating knob 50, a toggle member 60, and a driving device 70.

Specifically, the lock tongue 20 can be installed in the lock case 10 of the lock, and can move between the unlocking position and the locking position, and when the unlocking position, the lock tongue 20 retracts and hides into the lock case 10, and when the locking position, the lock tongue 20 extends out of the lock case 10 and penetrates into the lock hole on the locked object, and the locked object is locked and fixed.

The pivot shaft 30 has a central axis extending in the up-down direction, and the pivot shaft 30 may be provided on the lock case 10 to pivot along its own central axis. One end of a rotating arm 40 is connected to the pivot shaft 30, and the other end of the rotating arm 40 is connected to the locking bolt 20, so as to push the locking bolt 20 to move between the unlocking position and the locking position. That is, pivot arm 40 is connected between pivot shaft 30 and locking bolt 20, and when pivot shaft 30 rotates around its central axis, pivot shaft 30 can drive pivot arm 40 to rotate, and locking bolt 20 can move along with rotation of pivot arm 40.

An operating knob 50 is connected to the pivot shaft 30 for operation by a user to rotate the rotating arm 40. The toggle 60 is configured to be rotatable about the central axis relative to the pivot shaft 30 and to urge the swivel arm 40 to rotate during rotation. The driving device 70 is connected to the toggle member 60 to drive the toggle member 60 to rotate.

The operation knob 50 may be disposed on the lock case 10 and fixed circumferentially relative to the pivot shaft 30, and a user may apply a force to rotate the pivot shaft 30 by the operation knob 50, and then rotate the pivot arm 40 by the pivot shaft 30, and finally move the locking bolt 20 between the unlocking position and the locking position by the pivot arm 40. The toggle 60 is driven by the driving device 70 to rotate around the central axis of the pivot shaft 30 relative to the pivot shaft 30, and the toggle 60 pushes the rotating arm 40 to rotate during rotation, and finally the bolt 20 is driven to move between the unlocking position and the locking position by the rotating arm 40, for example, in the example of fig. 1 to 10, the toggle 60 extends downwards, the distance between the toggle 60 and the central axis of the pivot shaft 30 is less than the length of the rotating arm 40, when the toggle 60 rotates, the toggle 60 abuts against the side surface of the rotating arm 40, and as the toggle 60 continues to rotate, the toggle 60 can push the rotating arm 40 to rotate.

In specific use, when manual unlocking is required, a user can apply an acting force through the operation knob 50 to drive the pivoting shaft 30 to rotate, the pivoting shaft 30 is utilized to drive the rotating arm 40 to rotate, and the rotating arm 40 further pushes the locking bolt 20 to move from the locking position to the unlocking position, so that manual unlocking is realized. When the electronic unlocking is needed, a user can trigger the driving device 70 to start through the modes of inputting a password, inputting a fingerprint, identifying a human face and the like, the driving device 70 drives the toggle piece 60 to rotate relative to the pivot shaft 30, the toggle piece 60 rotates to abut against the side surface of the rotating arm 40 and pushes the rotating arm 40 to rotate, and the rotating arm 40 further pushes the bolt 20 to move from the locking position to the unlocking position, so that the electronic unlocking is realized.

It should be noted that, since the toggle 60 and the pivot shaft 30 can rotate relatively, the operation knob 50 is used to drive the pivot shaft 30 to rotate, and the pivot shaft 30 does not drive the toggle 60 to move when pushing the rotating arm 40 to rotate; similarly, in the process of driving the rotating arm 40 to rotate by using the toggle piece 60, the pivot shaft 30 and the operation knob 50 are not driven to move, so that the manual unlocking and the electric unlocking can be independently controlled, and the reliability of the manual unlocking and the electric unlocking is ensured.

According to the embodiment of the utility model provides a spring bolt actuating mechanism, drive arrangement 70 drives and dials piece 60 and rotates and promote rotor arm 40 rotatory with the central axis of pivotal axis 30, and then promote spring bolt 20 through rotor arm 40 and move between the position of unblanking and the position of locking, and operating knob 50 links to each other with pivotal axis 30, can supply the user operation and promote rotor arm 40 rotatory, and then promote spring bolt 20 through rotor arm 40 and move between the position of unblanking and the position of locking, so, can realize the independent control of electronic unblock and manual unblock, its simple structure is compact, can use in the tool to lock that the size requirement is littleer, for example glass door lock etc., and simultaneously, also can reduce cost. In addition, the manual unlocking and the electric unlocking have high reliability.

It should be noted that the movement form of locking bolt 20 is not limited in this application, and for example, locking bolt 20 rotates with rotation of rotating arm 40, or locking bolt 20 moves with rotation of rotating arm 40.

Correspondingly, referring to fig. 5 to 10, in an example of the present invention, the locking bolt 20 is formed in a linear type and moves between the unlocking position and the locking position, for example: a linear slide groove is provided in the lock case 10, at least a portion of the locking bolt 20 is slidably fitted in the linear slide groove, and the other end of the rotary arm 40 is slidably connected to the locking bolt 20, so that the locking bolt 20 can be pushed to move between the unlocked position and the locked position when the rotary arm 40 is rotated.

Referring to fig. 1 to 4, in another example of the present invention, locking bolt 20 is formed in an arc shape and rotates between the unlocked position and the locked position, for example: the locking bolt 20 is in the shape of a circular arc, the center of the circular arc of the locking bolt 20 is located on the central axis of the pivot shaft 30, and one end of the locking bolt 20 is fixedly connected to the other end of the rotating arm 40, so that when the rotating arm 40 rotates, the locking bolt 20 can be pushed to rotate between the unlocking position and the locking position.

Referring to fig. 3 to 4 and 7 to 10, in some embodiments of the present invention, the driving device 70 includes a driving motor 701 and a gear transmission mechanism, the gear transmission mechanism is connected to an output shaft of the driving motor 701, and the toggle member 60 is disposed on the gear transmission mechanism.

It will be understood that the gear transmission mechanism may comprise a gear or a plurality of gears, when the gear transmission mechanism is a gear, the gear is directly connected to the output shaft of the driving motor 701, and the gear is coaxially arranged with the pivot shaft 30, for example, the gear is pivotally arranged in the lock case 10, and the dial 60 is eccentrically arranged on the gear, so that when the driving motor 701 is operated, the driving gear is driven by the driving motor 701 to rotate, and the dial 60 can rotate around the central axis of the pivot shaft 30. When the gear transmission mechanism includes a plurality of gears, the gears are engaged with each other to form a gear set, the gear set includes a power input gear and a power output gear, the power input gear is connected to the output shaft of the driving motor 701, the power output gear is coaxially disposed with the pivot shaft 30, and the toggle member 60 is eccentrically disposed on the power output gear, so that when the driving motor 701 operates, the driving motor 701 drives the gear set to rotate, and the power output gear in the gear set drives the toggle member 60 to rotate around the central axis of the pivot shaft 30.

Therefore, when the driving motor 701 works, the poking piece 60 is driven to rotate through the gear transmission mechanism, so that the rotating driving of the poking piece 60 is realized, the structure is simple, and the poking piece 60 rotates stably and reliably.

In one embodiment of the present invention, the gear transmission mechanism comprises a first conical gear 702 and a second conical gear 703, the axis of the first conical gear 702 coincides with the axis of the pivot shaft 30; the second conical gear 703 is connected to the output shaft of the driving motor 701 and is engaged with the first conical gear 702; the toggle member 60 is eccentrically disposed on the first conical gear 702 and extends in the up-down direction.

In the example of fig. 3 to 4 and 7 to 10, the first conical gear 702 is pivotally mounted in the lock case 10, and the axis thereof extends in the up-down direction and is coaxial with the pivot shaft 30, the toggle member 60 is located on the bottom surface of the first conical gear 702 and protrudes downward, and the toggle member 60 is offset from the center of the first conical gear 702, and the axis of the second conical gear 703 extends in the horizontal direction. When the driving motor 701 drives the second conical gear 703 to rotate, the second conical gear 703 drives the first conical gear 702 to rotate, at this time, the toggle member 60 rotates around the axis of the first conical gear 702, when the toggle member 60 rotates to a certain angle, the toggle member 60 abuts against the side surface of the rotating arm 40, and the rotating arm 40 can be pushed to rotate by the continuous rotation of the toggle member 60, so that the driving of the rotating arm 40 is realized.

In this embodiment, the axis of the first conical gear 702 extends in the vertical direction, and the axis of the second conical gear 703 extends in the horizontal direction, that is, the axes of the first conical gear 702 and the second conical gear 703 are vertically arranged, and the driving motor 701 is connected with the second conical gear 703, so that the structure of the lock tongue driving mechanism is simpler and more compact, so that the lock tongue driving mechanism can be applied to a lock with a smaller size.

Referring to fig. 3 to 4 and 7 to 10, in some embodiments of the present invention, a first position detector 80 and a second position detector 81 are further included; the first position detector 80 is used for detecting whether the locking bolt 20 is in the unlocking position; the second position detector 81 is configured to detect whether the locking bolt 20 is in the locked position.

That is, the first position detector 80 may detect whether the locking bolt 20 is located at the unlocking position, and the second position detector 81 may detect whether the locking bolt 20 is located at the locking position, and when it is determined that the locking bolt 20 reaches the unlocking position or the locking position, the driving motor 701 stops operating, thereby controlling the driving motor 701, and ensuring that the locking bolt 20 is driven by the driving motor 701 to accurately reach the unlocking position or the locking position.

Further, a third position detector 82 is included, the third position detector 82 is configured to detect whether the dial 60 is located at an origin position, and when the dial 60 is located at the origin position, the locking bolt 20 is driven by the operating knob 50 to be movable between the locked position and the unlocked position.

That is, the origin position is a position where the toggle 60 is far from the rotating arm 40, and when the user rotates the rotating arm 40 by operating the knob 50, the toggle 60 does not interfere with the rotating arm 40, thereby ensuring that the locking bolt 20 can be driven to move between the locked position and the unlocked position after the rotating arm 40 rotates.

In a specific application, after the driving motor 701 rotates in one direction (for example, forward direction), and the bolt 20 is driven by the toggle element 60 to move to the locking position, the driving motor 701 rotates in reverse direction, so that the toggle element 60 rotates to the original position, at this time, the toggle element 60 is away from the side surface of the rotating arm 40, and further, a subsequent user can conveniently drive the rotating arm 40 by using the operation knob 50, so that the rotating arm 40 rotates in reverse direction to push the bolt 20 to move to the unlocking position, and manual unlocking is realized. Similarly, when the driving motor 701 rotates in another direction (for example, in the reverse direction), and after the latch bolt 20 is driven by the toggle element 60 to move to the locked position, the driving motor 701 rotates in the forward direction, so that the toggle element 60 rotates to the original position, at this time, the toggle element 60 is away from the side surface of the rotating arm 40, and then a subsequent user can conveniently drive the rotating arm 40 by using the operation knob 50, so that the rotating arm 40 rotates in the reverse direction to push the latch bolt 20 to move to the locked position, and manual locking is realized.

Referring to fig. 3 to 4, in an embodiment of the present invention, the toggle member 60 is configured to push the locking bolt 20 to move from the unlocked position to the locked position when the driving motor 701 rotates in one of the forward direction and the reverse direction, and push the locking bolt 20 to move from the locked position to the unlocked position when the driving motor 701 rotates in the other of the forward direction and the reverse direction.

Illustratively, when the driving motor 701 rotates in the forward direction, the toggle piece 60 is used to push the rotating arm 40 to rotate clockwise (in the direction of arrow a in fig. 3), and the rotating arm 40 further drives the locking bolt 20 to rotate to the locking position, and when the driving motor 701 rotates in the reverse direction, the toggle piece 60 is used to push the rotating arm 40 to rotate counterclockwise (in the direction of arrow B in fig. 4), and the rotating arm 40 further drives the locking bolt 20 to rotate to the unlocking position, so that electric unlocking and locking are realized;

that is, in the present embodiment, the unlocking and locking control of lock tongue 20 are realized by the forward rotation and the reverse rotation of drive motor 701, respectively, and the structure is simpler.

Referring to fig. 7 to 10, in another embodiment of the present invention, the lock bolt further includes an elastic restoring member 100 for driving the lock bolt 20 to move from the unlocking position to the locking position, for example, the elastic restoring member 100 is a torsion spring, one end of the torsion spring is fixedly connected to the lock case 10, and the other end of the torsion spring is fixedly connected to the rotating arm 40.

The toggle member 60 is configured to push the locking bolt 20 to move from the locked position to the unlocked position when the driving motor 701 rotates in one of the forward and reverse directions.

That is, the elastic restoring member 100 provides an elastic force, which acts on the rotating arm 40 or directly acts on the locking bolt 20, so as to force the locking bolt 20 to move from the unlocking position to the locking position without any other external force, and to maintain the locking bolt at the locking position, thereby achieving locking. When the unlocking is required, the driving motor 701 rotates in one direction to drive the locking bolt 20 to overcome the elastic force of the elastic reset piece 100, and the locking bolt moves from the locking position to the unlocking position, so that the unlocking is realized.

In this embodiment, the driving motor 701 and the elastic reset member 100 are used to respectively control unlocking and unlocking, and the elastic reset member 100 can ensure more reliable locking.

Referring to fig. 3 to 4 and 7 to 10, in some embodiments of the present invention, the first position detector 80, the second position detector 81 and the third position detector 82 are optical coupling sensors, the rotating arm 40 or the locking tongue 20 is provided with a first blocking piece 90, the first bevel gear 702 is provided with a second blocking piece 91, and the first position detector 80 and the second position detector 81 can be installed in the lock case 10.

When the first flap 90 rotates to be opposite to the first position detector 80, the first position detector 80 is triggered to determine that the locking bolt 20 is in the unlocked position. When the first blocking piece 90 rotates to be opposite to the second position detector 81, the second position detector 81 is triggered to determine that the locking bolt 20 is in the unlocking position. When the second shutter 91 rotates to be opposite to the third position detector 82, the third position detector 82 is triggered to determine that the toggle 60 is located at the origin position.

In this way, when the first blocking piece 90 moves to the first position detector 80 or the second position detector 81 along with the rotating arm 40 or the locking bolt 20, the corresponding first position detector 80 or the second position detector 81 is triggered, and the locking bolt 20 is accurately determined to reach the unlocking position or the locking position. Similarly, when the second blocking piece 91 moves to the third position detector 82, the third position detector 82 is triggered, and it is accurately determined that the toggle member 60 reaches the origin position.
