Description

Technical Field

[0001] This invention relates to the field of electronic lock technology, and more specifically, to an electronic handle lock. Background Technology

[0002] In the field of electronic smart handle locks, locking is achieved by engaging the handle, and unlocking is achieved by releasing the engagement point. However, in this existing technology, unlocking can be achieved simply by prying open the handle, resulting in low security performance of the lock. Summary of the Invention

[0003] This invention discloses an electronic handle lock, which aims to improve the problems mentioned above.

[0004] The present invention adopts the following solution:

[0005] This application provides an electronic handle lock, including a housing and a latch. The housing is provided with a movable handle. The lock also includes: a first rotating shaft connected to the handle, a second rotating shaft connected to the latch, and a slider movably connected between the first and second rotating shafts. The slider is connected to a drive module to control its switching between a first position and a second position. When the slider is in the first position, it is simultaneously connected to the first and second rotating shafts so that rotating the handle can drive the latch to rotate and unlock. When the slider is in the second position, the first rotating shaft is disconnected from the slider so that the latch is in a locked state.

[0006] The handle on the housing has a pulled-up state and a fastened state. When the handle is in the fastened state, the drive module controls the slider to be in the second position to be in the locked state. When the handle is in the pulled-up state and the slider is in the first position, it is in the unlockable state.

[0007] Furthermore, the drive module includes a lever, a first motor, a stop block, and a drive assembly. A first elastic element is disposed between the slider and the second rotating shaft to provide a directional force toward the first rotating shaft to the slider. The lever is oscillating between the slider and the first rotating shaft. The drive assembly connects the handle and the lever to drive the lever to position the slider in a second position when the handle is in a locked state. The first motor is adapted to connect to the stop block, which is disposed on one side of the lever to limit the lever's oscillation, thereby keeping the slider in a locked state at the second position.

[0008] Furthermore, the drive assembly includes a push rod and a connector. The connector is oscillatingly disposed within the housing and adapted to connect with the lever. Both ends of the push rod are adapted to abut against the handle and the connector, respectively. When the handle is in the fastened state, the handle presses against one end of the push rod to drive the connector to oscillate, thereby driving the lever to oscillate and controlling the slider to move from the first position to the second position. When the handle is in the pulled-up state, the push rod releases its contact with the connector, allowing the connector to oscillate freely.

[0009] Furthermore, a second elastic element is provided on the side of the push rod near the connector to drive the push rod to reset when the handle is in the pulled-up state.

[0010] Furthermore, a cam structure is provided on the output shaft of the first motor to drive the stop away from the lever to remove the restriction on the lever.

[0011] Furthermore, the housing is provided with a movable groove suitable for installing the stop block, and a third elastic element is provided in the movable groove to drive the stop block to move toward the lever, thereby restricting the lever from swinging.

[0012] Furthermore, the housing also includes a second motor and a lock cylinder head suitable for inserting a passive key. The lock cylinder head is movably provided with a lock cylinder tail suitable for driving the stop block to move. The second motor is adapted to rotate under the power supply of the passive key so that the lock cylinder head can drive the lock cylinder tail to rotate, thereby driving the stop block to remove the restriction on the lever to achieve unlocking.

[0013] Furthermore, the lock cylinder tail is sleeved on the outside of the lock cylinder head, and a groove is provided on the lock cylinder tail. The second motor is disposed on one side of the lock cylinder head, and a ball is disposed between the second motor and the lock cylinder head. The second motor is adapted to drive the ball into the groove so that when the lock cylinder head rotates, it synchronously drives the lock cylinder tail to rotate, thereby controlling the movement of the stop block through the lock cylinder tail.

[0014] Furthermore, the front of the housing is provided with a mounting groove suitable for the handle to be inserted in the locked state, and the lock cylinder head is disposed in the mounting groove.

[0015] Furthermore, the handle is rotatably disposed at the outer end of the first rotating shaft to switch between a fastened state and a pulled-up state, and the handle is adapted to rotate about a direction perpendicular to the central axis of the first rotating shaft.

[0016] Beneficial effects:

[0017] This invention utilizes a slider for axial movement to allow the handle to rotate freely. When the slider is moved away from the handle (away from it), the handle can rotate 360 ​​degrees, and unlocking is impossible during this process. When the slider is moved towards the handle, the handle can rotate the latch 90° to unlock. When the handle is closed, a push rod automatically locks the lock by moving the slider away from the handle. In this design, unlocking is achieved by a motor sliding a stop away, causing the slider to be pushed towards the handle by the spring force, reaching a first position where unlocking is possible. Furthermore, a passive lock structure is included to allow unlocking via a passive key when the device's power supply fails. Attached Figure Description

[0024] Combination Figures 1 to 5As shown, this embodiment provides an electronic handle lock, including a housing 1 and a latch 3. The housing 1 is provided with a movable handle 4. It also includes: a first rotating shaft 5 connected to the handle 4, a second rotating shaft 6 connected to the latch 3, and a slider 7 movably connected between the first rotating shaft 5 and the second rotating shaft 6. The slider 7 is connected to a drive module to control its switching between a first position and a second position. When the slider 7 is in the first position, it is simultaneously connected to the first rotating shaft 5 and the second rotating shaft 6 so that rotating the handle 4 can drive the latch 3 to rotate for unlocking. When the slider 7 is in the second position, the first rotating shaft 5 is disconnected from the slider 7 so that the latch 3 is in a locked state. The handle 4 has a pulled-up state and a fastened state on the housing 1. When the handle 4 is in the fastened state, the drive module controls the slider 7 to be in the second position to be in a locked state. When the handle 4 is in the pulled-up state and the slider 7 is in the first position, it is in an unlockable state.

[0025] Combination Figures 1 to 2 As shown, in this embodiment, the electronic handle 4 lock includes a housing, a back cover, and a sealing gasket connecting the housing and the back cover. The handle 4 is disposed on one side of the housing and located on the front of the housing for convenient user operation. A mounting groove 101 is provided on the front of the housing for the handle 4 to be embedded in the locked state, and the lock cylinder head 19 is disposed in the mounting groove 101. Further, a sensing window is also provided on the front of the housing for user identification by IC sensing, touch, fingerprint, etc., so that after successful identification, the drive module can be controlled to rotate to unlock. The verification and identification method can adopt existing technical solutions, which are not limited here. A latch 3 is provided on the other side of the housing, which is used to lock in a position such as a door frame. The handle 4 is rotatably disposed on the outer end of the first rotating shaft 5 to switch between the locked state and the pulled state, and the handle 4 is adapted to rotate about a direction perpendicular to the central axis of the first rotating shaft 5. In a preferred embodiment, a torsion spring is provided on the handle 4 and the first rotating shaft 5.

[0026] In this embodiment, a sleeve 2 is provided on the back of the housing for mounting the second rotating shaft 6. The second rotating shaft 6 is mounted on the sleeve 2 and connected to the latch 3, driving the latch 3 to rotate. The slider 7 has a square shape to insert into a square slot on the second rotating shaft 6, so that the second rotating shaft 6 can rotate synchronously when the slider 7 rotates. The first rotating shaft 5 and the slider 7 can also be connected by a square structure and a square slot, so that when the slider 7 moves to engage with the first rotating shaft 5, the rotation of the first rotating shaft 5 can drive the slider 7 to rotate. In this embodiment, when the slider 7 is in the first position, it is simultaneously connected to the first rotating shaft 5 and the second rotating shaft 6 to put the latch 3 in the unlocked state; when the slider 7 is in the second position, the first rotating shaft 5 is disconnected from the slider 7 to put the latch 3 in the locked state; that is, the slider 7 can be connected to the first rotating shaft 5 and the second rotating shaft 6 simultaneously, or only to the second rotating shaft 6.

[0027] The drive module includes a lever 9, a first motor 10, a stop block 12, and a drive assembly. A first elastic element 8 is provided between the slider 7 and the second rotating shaft 6 to provide a force to the slider 7 in the direction of the first rotating shaft 5. The lever 9 is oscillating between the slider 7 and the first rotating shaft 5. The drive assembly connects the handle 4 and the lever 9 to drive the lever 9 to position the slider 7 in a second position when the handle 4 is in a locked state. The first motor 10 is adapted to connect to the stop block 12, which is located on one side of the lever 9 to limit its oscillation, thereby keeping the slider 7 in a locked state at the second position. Specifically, the driving assembly includes a push rod 13 and a connector 14. The connector 14 is oscillatingly disposed within the housing and adapted to connect with the lever 9. The two ends of the push rod 13 are respectively connected to the handle 4 and the connector 14. When the handle 4 is in the locked state, the handle 4 presses against the push rod 13 to drive the connector 14 to oscillate, thereby driving the lever 9 to oscillate and control the slider 7 to move from a first position to a second position. When the handle 4 is in the pulled-up state, the push rod 13 releases its force on the connector 14, allowing the connector 14 to oscillate freely. The housing is provided with a movable groove 16 suitable for installing the stop 12. A third elastic element 17 is disposed within the movable groove 16 to drive the stop 12 to move towards the lever 9, thereby restricting the oscillation of the lever 9. The stop 12 is disposed below the pivot of the lever 9 and is used to press against the side of the lever 9 facing the handle 4 below, thereby restricting the lever 9 from rotating towards the handle 4. A second elastic element 15 is provided on the side of the push rod 13 near the connector 14 to drive the push rod 13 to reset when the handle 4 is in the pulled-up state.

[0028] The lever 9 is located in the area between the slider 7 and the first rotating shaft 5. A rotating shaft 91 is provided along the length of the lever 9, allowing the lever 9 to rotate around the rotating shaft 91. The connecting member 14 is located on the side of the lever 9 away from the handle 4. The connecting member 14 is bent and has another rotating shaft 141 at the bend, allowing the connecting member 14 to swing around this rotating shaft 141. Here, the lever 9 is located at the upper part of the rotating shaft 91 for contact with the slider 7, and at the lower part of the rotating shaft 91 for contact with the connecting member 14. The outer end of the push rod 13 is adapted to extend out of the mounting groove 101, and the other end is adapted to contact and connect with the upper end of the connector 14. When the handle 4 is rotated from the pulled-up state to the locked state, the inner side of the handle 4 will drive the push rod 13 to move inward to press against the upper end of the connector 14, thereby causing the connector 14 to rotate around its rotation axis 141. The lower end of the connector 14 will rotate towards the lower end of the lever 9, thereby driving the lever 9 to rotate around its rotation axis, causing the upper end of the lever 9 to move the slider 7 toward the second position. That is, when the handle 4 is in the locked state, the locking tongue 3 cannot be rotated by rotating the handle 4, thus achieving the effect of automatic locking when the handle 4 is locked. At this time, even if the handle 4 is pried open, the lever 9 is limited by the stop block 12, so the elastic force of the first elastic element 8 cannot reset the slider 7 to the first position, and therefore it is also in the locked state. It should be noted that in this embodiment, the handle 4 and the top rod 13 are connected by abutting. When the handle is fastened, it abuts against the top rod 13, and when the handle is pulled up, it separates from the top rod 13.

[0029] In one embodiment, the output shaft of the first motor 10 within the aforementioned drive module is connected to a cam structure. When the first motor 10 receives a command from the control system, it can rotate to drive the cam structure to rotate, thereby driving the stop 12 to disengage from the lever 9. The control system may be a PCBA board disposed within the housing, connected to a sensing and identification module, used to control the first motor 10 to rotate and unlock when the user's identification is successful.

[0030] Combination Figures 3 to 4 As shown, in another embodiment, the housing further includes a second motor 18 and a lock cylinder head 19 adapted to insert a passive key. The lock cylinder head 19 has a lock cylinder tail 20 movably disposed thereon, adapted to drive the stop block 12. The second motor 18 is adapted to rotate under the power of the passive key, so that the lock cylinder head 19 can drive the lock cylinder tail 20 to rotate, thereby driving the stop block 12 to release the restriction on the lever 9 to achieve unlocking. Here, the passive key is a conventional structure, which includes a power module and a key module. The key module is adapted to connect to the lock cylinder head 19, thereby driving the lock cylinder head 19 to rotate, and simultaneously supplying power to the second motor 18.

[0031] The lock cylinder head 19 can be disposed within the mounting groove 101. When the handle 4 is rotated to the pulled-up position, a passive key can be inserted for operation. In this embodiment, the lock cylinder tail 20 is sleeved on the outside of the lock cylinder head 19 and is adapted to rotate on the lock cylinder head 19. When the second motor 18 is not working, rotating the lock cylinder head 19 will not cause the lock cylinder tail 20 to rotate. A groove 201 is provided on the lock cylinder tail 20. The lock cylinder head 19 is provided with multiple arc-shaped grooves 1901 around its circumference. The second motor 18 is disposed on one side of the lock cylinder head 19, and a ball bearing 21 is provided between the second motor 18 and the lock cylinder head 19. The second motor 18 is adapted to drive the ball bearing 21 into the groove 201 so that when the lock cylinder head 19 rotates, it synchronously drives the lock cylinder tail 20 to rotate, thereby controlling the movement of the stop block 12 through the lock cylinder tail 20. The second motor 18 is equipped with a cam, which drives a ball bearing 21 located on the side of the groove 201 into the groove 201 and the arc-shaped groove 1901 when rotating. This allows the lock cylinder head 19 to rotate, and the ball bearing 21 synchronously drives the lock cylinder tail 20 to rotate. The lock cylinder tail 20 has a protrusion structure 202, which is adapted to rotate to drive the stop block 12 away from the lever 9, thereby causing the slider 7 to switch to the first position for unlocking under the action of the first elastic element 8. It should be noted that the second motor 18 can also be connected to another control system. When the passive key is inserted, it needs to be matched with the identification module set on the control system. Only when the passive key successfully matches the control system can the second motor 18 operate.

[0032] By setting the structure of the second motor 18 and the lock cylinder head 19 and lock cylinder tail 20 to drive the movement of the stop 12 to achieve unlocking, it can be used as an emergency key when the power inside the lock is exhausted. Moreover, the second motor 18 and the first motor 10 do not interfere with each other, realizing the coexistence of two unlocking methods and making the unlocking methods more diverse.

[0033] In this embodiment, when the slider 7 is moved in the opposite direction of the handle 4 (i.e. away from the handle 4), the handle 4 can rotate 360 ​​degrees and cannot be unlocked during this process. When the slider 7 is moved towards the handle 4, the handle 4 can drive the locking tongue 3 to rotate 90 degrees to unlock. When the handle 4 is closed, a push rod 13 will push the slider 7 in the opposite direction of the handle 4 to achieve automatic locking, realizing automatic locking when the handle 4 is fastened. When the handle 4 is pried open, synchronous verification and identification are required to release the stop 12 from the restriction of the lever 9 in order to unlock, which improves security.

All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.
