The specific structure of the automatic electronic lock will be mainly described below.

Referring to fig. 1 to 10, in an embodiment of the present invention, the automatic electronic lock includes a lock body 20 and a key cylinder 10, the key cylinder 10 including a housing 100, a shackle 200, and a driving mechanism. The housing 100 has an accommodating space, and the housing 100 is formed with a mortise lock groove 110 communicating the accommodating space with the outside; the lock catch 200 is movably mounted in the accommodating space, and the lock catch 200 is provided with a limiting groove 210; the driving mechanism is in driving fit with the lock catch 200, so that the lock catch 200 has an unlocking state and a locking state; in the unlocked state of the lock catch 200, the notch of the limiting groove 210 is communicated with the mortise lock groove 110, and the lock body 20 can enter the limiting groove 210 from the outside of the housing 100 through the mortise lock groove 110; in the locked state of the lock catch 200, the notch of the limiting groove 210 is located outside the mortise lock groove 110, and the lock body 20 is limited at the communication position between the limiting groove 210 and the mortise lock groove 110. The lock body 20 has various shapes, for example, the lock body 20 is in a ring shape, and when the lock catch 200 is in a locked state, the groove wall forming the limiting groove 210 penetrates through the lock body 20, so that the lock body 20 is locked on the lock cylinder 10. When the electronic lock is in practical use, the main control circuit can be arranged on the automatic electronic lock, the driving mechanism is electrically connected with the main control circuit, and the driving mechanism can be controlled by the main control circuit to control unlocking and locking of the automatic electronic lock.

The driving mechanism includes a driving motor 310, a driving gear 320, and a transmission gear 330, wherein the driving gear 320 is connected with a rotating shaft of the driving motor 310 to rotate along with the rotation of the rotating shaft, the transmission gear 330 is meshed with the driving gear 320, and the transmission gear 330 is in driving fit with the lock catch 200. Specifically, a first elastic member 400 is installed in the housing 100, where the first elastic member 400 includes, in order in an extending direction, a limiting arm 410, a connecting section 420, and a rotating arm 430, where the limiting arm 410 and the rotating arm 430 are disposed at an included angle, the limiting arm 410 and the rotating arm 430 have elasticity, and/or the connecting section 420 has elasticity; the lock catch 200 is connected with the rotating arm 430 and can rotate along with the rotation of the lock catch 200, the transmission gear 330 and the lock catch 200 are arranged up and down, a pushing piece 331 is convexly arranged on one surface of the transmission gear 330 facing the lock catch 200, a pushed piece 220 is convexly arranged on one surface of the lock catch 200 facing the transmission gear 330, and on the rotation track of the transmission gear 330, the pushing piece 331 has a pushing state for extruding the pushed piece 220 and an idle state for leaving the pushed piece 220; when the pushing member 331 is in the pushing state, the pushed member 220 drives the lock catch 200 to enter the first state, the rotating arm 430 moves in a direction approaching to the limiting arm 410, and the first elastic member 400 is in a compressed state; when the pushing member 331 is in the idle state, the first elastic member 400 is reset, the rotating arm 430 drives the lock catch 200 to reset, and the lock catch 200 enters the second state; one of the first state and the second state is the unlocking state, and the other is the locking state.

In this embodiment, the working process of the automatic electronic lock is described by taking the first state as a locking state and the second state as an unlocking state as an example: when the automatic electronic lock is in an unlocking state, that is, when the notch of the limiting groove 210 is communicated with the mortise lock groove 110, the lock body 20 is inserted into the mortise lock groove 110 and enters the limiting groove 210, then the driving motor 310 is controlled to work, so that the driving gear 320 rotates, the driving gear 320 rotates clockwise to rotate the transmission gear 330 counterclockwise as illustrated by the clockwise rotation of the driving gear 320, the protruding pushing piece 331 of the transmission gear 330 presses the pushed piece 220 of the lock catch 200 in the rotating process, so that the lock catch 200 rotates clockwise until the notch of the limiting groove 210 of the lock catch 200 is positioned outside the mortise lock groove 110, and the lock body 20 cannot exit from the mortise lock groove 110 through the notch of the limiting groove 210, so that the lock body 20 is limited at the communicating position of the limiting groove 210 and the mortise lock groove 110, so that the lock body 20 is locked on the lock catch 200, and the lock catch 200 rotates clockwise and simultaneously the lock catch 200 drives the rotating arm 430 of the first elastic piece 400 to move in a direction close to the limiting arm 410, so that the first elastic piece 400 is in a compressed state; when unlocking is needed, the driving motor 310 is controlled to continue to work, the driving gear 320 continues to rotate clockwise, the transmission gear 330 continues to rotate anticlockwise, after the pushing piece 331 leaves the pushed piece 220, the first elastic piece 400 resets, the rotating arm 430 drives the lock catch 200 to reset, the lock catch 200 is restored to be communicated with the locking groove 110 through the notch of the limiting groove 210, and thus, the lock body 20 can withdraw from the locking groove 110 through the notch of the limiting groove 210, and unlocking of the automatic electronic lock is completed. In the embodiment, unlocking and locking of the automatic electronic lock are realized in a gear transmission mode, the operation is stable and reliable, and the stable and reliable of the automatic electronic lock is ensured.

Wherein the first elastic member 400 includes a torsion spring, even more, the first elastic member 400 may be a torsion spring. In order to ensure the stability of the installation of the first elastic member 400, the lock catch 200 is provided with a first limit post 230, a connection section 420 of the first elastic member 400 is annular, and the connection section 420 is sleeved on the first limit post 230, so that the first elastic member 400 is not easy to walk when deformed. There are many ways to avoid the first elastic member 400 from being displaced, for example, in other embodiments, the housing 100 is provided with a second limiting post 120, and the second limiting post 120 abuts against a side of the limiting arm 410 facing away from the rotating arm 430.

In some embodiments, to improve stability of the lock catch 200 in the unlocked state and the locked state, the lock cylinder 10 further includes a limiting member 500, where the limiting member 500 is located on a side of the lock catch 200 facing away from the transmission gear 330, a surface of the lock catch 200 facing the limiting member 500 is convexly provided with a limiting protrusion 240, and the limiting member 500 is movable along a first direction, and the first direction is parallel to a rotation axis of the lock catch 200, so that the limiting member 500 has a limiting position and an avoidance position; when the limiting member 500 is at the limiting position, the side wall of the limiting protrusion 240 is clamped on the side wall of the limiting member 500, and the lock catch 200 is in the unlocking state or the locking state; when the limiting member 500 is in the avoiding position, the limiting member 500 is located at a side of the limiting protrusion 240 away from the lock catch 200, so that the lock catch 200 can be switched between the unlocking state and the locking state.

In this embodiment, when the limiting member 500 is located at the limiting position or the avoiding position by moving the limiting member 500, the side wall of the limiting protrusion 240 of the lock catch 200 is clamped on the side wall of the limiting member 500, so that the lock catch 200 is stably located in the current unlocking state or locking state, it should be noted that, when the lock catch 200 is in different states, the side wall of the limiting protrusion 240 is clamped on the opposite position of the limiting member 500, for example, when the lock catch 200 is in the locking state, the limiting protrusion 240 is located at the rear of the limiting member 500, and when the lock catch 200 is in the unlocking state, the limiting protrusion 240 is located at the front of the limiting member 500, which means that the front and the rear are only a relative reference direction, not the specific limiting direction. When the limiting member 500 is in the avoidance position, the limiting member 500 is located on a side of the limiting protrusion 240 away from the lock catch 200, that is, the limiting member 500 does not limit rotation of the lock catch 200, so that the lock catch 200 can be switched between the unlocking state and the locking state.

The limiting member 500 may be movable along a first direction, so that the limiting member 500 has a limiting position and a avoiding position, for example, in some embodiments, the lock cylinder 10 further includes a second elastic member 600, where the elastic member extends along the first direction, and one end of the second elastic member 600 is connected or abutted to the limiting member 500, and the other end of the second elastic member is abutted or connected to an inner wall of the housing 100. In this way, the stopper 500 can be moved by pressing the stopper 500 and releasing the stopper 500. Specifically, a surface of the transmission gear 330 facing away from the limiting member 500 is abutted against the inner wall of the housing 100 through an abutting member, a rotating ladder 332 is convexly arranged on a surface of the transmission gear 330 facing the limiting member 500, a matching ladder 510 is arranged on a surface of the limiting member 500 facing the transmission gear 330 corresponding to the rotating ladder 332, and the rotating ladder 332 has an abutting state and an avoiding state under the rotation track of the transmission gear 330; in the pressing state of the rotating ladder 332, the rotating ladder 332 presses the mating ladder 510, the second elastic member 600 is compressed between the limiting member 500 and the inner wall of the housing 100, and the limiting member 500 is in the avoiding position; in the avoidance state of the rotating ladder 332, the rotating ladder 332 is avoided from the matching ladder 510, the second elastic member 600 is reset, and the limiting member 500 is at the limiting position.

In this embodiment, in the rotation process of the transmission gear 330, when the rotating ladder 332 abuts against the matching ladder 510 of the limiting member 500, since one surface of the transmission gear 330 facing away from the limiting member 500 abuts against the inner wall of the housing 100 through the abutting member, the transmission gear 330 will not displace, but has a pressing force on the limiting member 500, so that the limiting member 500 moves, and the limiting member 500 is pressed to the avoiding position, so that the lock catch 200 can be switched between the unlocking state and the locking state, and meanwhile, the second elastic member 600 is pressed to be in the compressed state. When the transmission gear 330 continues to rotate, the rotating ladder 332 is kept away from the matching ladder 510, that is, after leaving the matching ladder 510, the limiting member 500 and the second elastic member 600 are removed by the pressing force, so that the second elastic member 600 resets and drives the limiting member 500 to reset, so that the limiting member 500 is restored to the limiting position, and the lock catch 200 is ensured to be stably in the current unlocking state or locking state.

To avoid the rotation of the limiting member 500, in some embodiments, one of the limiting member 500 and the inner wall of the housing 100 is provided with a third limiting post 130, and the other one is provided with a limiting hole 520, the third limiting post 130 is inserted into the limiting hole 520, and the extending direction of the third limiting post 130 and the hole depth direction of the limiting hole 520 are parallel to the first direction. The third limiting post 130 limits the moving direction of the limiting member 500, so that the limiting member 500 can move up and down along the first direction, but cannot rotate, and the working stability and reliability of the limiting member 500 are ensured, thereby ensuring the working stability and reliability of the automatic electronic lock.

In some embodiments, the limiting groove 210 has a first groove wall 211, in the unlocked state of the lock catch 200, an extending direction of the first groove wall 211 is set at an angle to a groove depth direction of the mortise lock groove 110, the first groove wall 211 is set facing a notch of the mortise lock groove 110, and the lock body 20 can abut against the first groove wall 211 under the action of external force to drive the lock catch 200 into the locked state. That is, in this embodiment, the lock body 20 may be pressed against the first groove wall 211 of the limiting groove 210 with force, so that the lock catch 200 rotates to the locking state, and thus, the locking function of the automatic electronic lock may be achieved even in the abnormal situation such as power failure of the automatic electronic lock.

The invention also provides electronic equipment, which comprises the automatic electronic lock, and the specific structure of the automatic electronic lock refers to the embodiment, and because the electronic equipment adopts all the technical schemes of all the embodiments, the electronic equipment at least has all the beneficial effects brought by the technical schemes of the embodiments, and the detailed description is omitted.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
