Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic lock, in particular, to a smart handle lock. BACKGROUND

[0002] The emergency unlocking assembly of the existing handle lock is usually a mechanical lock cylinder. The emergency unlocking lock cylinder is arranged at the handle handle. The conventional unlocking and emergency unlocking share the same locking member. The lock cylinder drives the locking member to move to realize the emergency unlocking. When the emergency unlocking is performed, the lock cylinder is rotated by inserting a key to directly drive the unlocking structure (such as a clutch top pin) to push the clutch structure, so that the lock is in an unlocked state. Therefore, the driving module needs to exert a sufficient driving force on the unlocking structure to enable the unlocking structure to push the clutch pin. If only the mechanical lock cylinder is replaced by an electronic lock cylinder, the driving module of the electronic lock cylinder needs to have a certain power, thereby being not conducive to reducing the size of the electronic lock cylinder, and thereby being not conducive to reducing the size of the emergency unlocking assembly. CONTENT OF THE UTILITY MODEL

[0003] The embodiment of the present application provides a smart handle lock, which can reduce the driving force required by the driving module of the electronic lock cylinder when the electronic lock cylinder is switched between unlocking and locking, thereby being conducive to reducing the size of the electronic lock cylinder.

[0004] The embodiment of the present application provides a smart handle lock, which comprises a handle assembly, a first electric unlocking assembly and a second electric unlocking assembly. The handle assembly comprises a handle, a handle shaft, a clutch plate, a base and a top pin. One end of the handle shaft is fixedly connected with the handle. The clutch plate is rotatably sleeved outside the handle shaft, and a locking groove is arranged on the side of the clutch plate facing the handle. The base is sleeved outside the handle shaft and fixedly connected with an external structure. The top pin is movably arranged in the handle along the axial direction of the handle shaft. The first electric unlocking assembly is arranged in the handle, and is used for locking or unlocking the clutch plate and the base. The second electric unlocking assembly is arranged in the handle and comprises an electronic lock cylinder, a sliding block and a first elastic member. One side of the sliding block is provided with an abutting guide surface corresponding to one end of the top pin. The sliding block has a locking position and an unlocking position along the radial direction of the handle shaft. The sliding block moves to the locking position under the action of the first elastic member and pushes the top pin to extend out of the handle and insert into the locking groove. The handle shaft is rotated relative to the clutch plate to drive the top pin to move away from the locking groove and drive the sliding block to move to the unlocking position. The electronic lock cylinder has a locking state of locking the sliding block at the locking position to lock the handle shaft and the clutch plate and an unlocking state of releasing the sliding block.

[0005] Specifically, when the first electric unlocking assembly fails or the battery is out of power (at this time the clutch plate and the base are locked), an external device (such as a mobile phone) can be connected to the second electric unlocking assembly, so that the electronic lock core in the second electric unlocking assembly releases the sliding block, so that the sliding block is no longer locked in the closed position, and then the sliding block is only limited by the elastic force provided by the first elastic member to make the tumbler disengage from the closed slot. At this time, the handle shaft can be rotated to drive the tumbler to disengage from the closed slot, and the end of the tumbler slides relative to the guide surface to drive the sliding block to move to the unlocking position. Thus, the handle shaft can rotate relative to the clutch plate and the base, and then the handle shaft can drive the unlocking mechanism (such as the lock tongue) of the smart handle lock to rotate, so that the smart handle lock switches between the unlocked state and the locked state. When it is necessary to lock the smart handle lock in the locked state, the handle can be rotated to drive the handle shaft to rotate, and then the tumbler is aligned with the closed slot, the sliding block moves to the closed position under the action of the first elastic member, and the tumbler is inserted into the closed slot. Then connect the external device to the second electric unlocking assembly, so that the electronic lock core in the second electric unlocking assembly locks the sliding block in the closed position, so that the sliding block limits the tumbler from disengaging from the closed slot, so that the handle shaft and the clutch plate are locked, and then the smart handle lock is locked in the locked state.

[0006] In the above technical solution, the electronic lock core in the second electric unlocking assembly is only used to lock the sliding block in the closed position, and the driving force for driving the tumbler to disengage from the closed slot when unlocking is provided by the operator, and the driving force for driving the sliding block to return to the closed position and driving the tumbler to be inserted into the closed slot again when locking is provided by the first elastic member. The driving force required by the driving module of the electronic lock core is smaller, thereby being beneficial to reducing the volume of the electronic lock core, and then being beneficial to reducing the volume of the smart handle lock.

[0007] In some embodiments, along the axial direction of the handle shaft, the side of the sliding block facing the electronic lock core is provided with a receiving groove. The electronic lock core includes a first driving module and a locking block, when the electronic lock core is in the locked state, the first driving module drives the locking block to insert into the receiving groove to lock the sliding block in the closed position; when the electronic lock core is in the unlocked state, the first driving module drives the locking block to exit the receiving groove.

[0008] In the technical solution, the locking block moves along the axial direction of the handle rotating shaft to be inserted into or withdrawn from the accommodating groove, and when the sliding block has a tendency to move towards the unlocking position, the groove wall of the accommodating groove and the locking block are in radial abutment along the handle rotating shaft, so that the driving force applied by the sliding block to the locking block is perpendicular to the direction in which the first driving module drives the locking block to move, further reducing the driving force required by the first driving module when the electronic lock cylinder locks the sliding block, reducing the power requirement of the first driving module, and further reducing the volume of the first driving module, thereby facilitating the further reduction of the volume of the electronic lock cylinder and the second electric unlocking assembly, and further facilitating the further reduction of the volume of the intelligent handle lock.

[0009] In some embodiments, the electronic lock cylinder includes a shell, a circuit control module arranged in the shell, a Type-C male head, a first driving module and a transmission rod, and a first spring. One end of the Type-C male head protrudes out of the shell and out of the handle, and the other end is connected with the circuit control module. The first driving module is in driving connection with the transmission rod. The locking block is movably sleeved on the transmission rod, and when the electronic lock cylinder is in the locked state, the locking block protrudes out of the shell; when the electronic lock cylinder is in the unlocked state, the locking block is retracted into the shell, and the inside of the locking block forms a receiving cavity. The first spring is arranged in the receiving cavity and sleeved on the transmission rod, and a first limiting protrusion is arranged on the outer circumferential surface of the transmission rod, and the first limiting protrusion penetrates between two turns of the first spring. The first driving module drives the transmission rod to rotate forward and reverse, so that the transmission rod pushes the locking block to protrude out of the shell and retract into the shell through the first spring.

[0010] Since the first spring is sleeved on the transmission rod and located in the receiving cavity, and the first limiting protrusion penetrates between the two turns of the first spring, when the first limiting protrusion rotates with the transmission rod, the first limiting protrusion will move along the spiral of the first spring, so that the first spring moves along the transmission rod, and the first spring abuts against the two wall portions of the receiving cavity in the movement direction. In turn, the first spring can provide an elastic force to the receiving cavity to drive the locking block to protrude out of the shell and retract into the shell.

[0011] Specifically, the external device (such as a mobile phone) provides power to the first drive module through the Type-C male head. When the locking block is retracted into the shell, the length of the portion of the first spring between the wall of the accommodating cavity close to the slider and the first limiting protrusion in the extension direction of the first spring reaches the maximum, so that the first spring in this portion exerts an elastic force on the wall of the accommodating cavity close to the slider to retract the locking block into the shell. When the locking block is switched to extend out of the shell, the first drive module drives the transmission rod to rotate forward to gradually reduce the length of the portion of the first spring between the wall of the accommodating cavity close to the slider and the first limiting protrusion in the extension direction of the first spring, and gradually increase the length of the portion of the first spring between the wall of the accommodating cavity away from the slider and the first limiting protrusion in the extension direction of the first spring. On the one hand, the elastic force provided by the portion of the first spring between the wall of the accommodating cavity close to the slider and the first limiting protrusion on the wall of the accommodating cavity close to the slider is gradually reduced, and on the other hand, the elastic force provided by the portion of the first spring between the wall of the accommodating cavity away from the slider and the first limiting protrusion on the wall of the accommodating cavity away from the slider is gradually increased to drive the locking block to extend out of the shell. When the locking block extends out of the shell and the first drive module has a tendency to continue to rotate, the transmission rod continues to rotate forward to make the first limiting protrusion continue to move in the extension direction of the first spring, thereby further increasing the length of the portion of the first spring between the wall of the accommodating cavity away from the slider and the first limiting protrusion in the extension direction of the first spring to provide a greater elastic force on the wall of the accommodating cavity away from the slider, so that the first drive module can continue to rotate.

[0012] In the above technical solution, when the locking block is switched to extend out of the shell or retract into the shell and the first drive module has a tendency to continue to rotate, the first drive module can continue to rotate, thereby reducing the probability of stalling of the first drive module and the risk of damage to the first drive module.

[0013] In some embodiments, the handle assembly further includes a dust cover slidably arranged on the side of the handle away from the base along the radial direction of the handle shaft, and the side of the handle away from the base is provided with a first opening for the one end of the Type-C male head to extend out. The dust cover has a closed position for closing the first opening and an open position for opening the first opening.

[0014] In the above technical solution, by arranging the dust cover to have a closed position for closing the opening, the dust cover can reduce the risk of external dust falling on the Type-C male head when not in use. At the same time, by arranging the dust cover to have an open position for opening the first opening, the risk of the dust cover interfering with the connection of the external device and the Type-C male head is reduced.

[0015] In some embodiments, the handle rotating shaft comprises a cover part and a rotating shaft part, the second opening is arranged on the side of the handle facing the base, the cover part seals the second opening, the rotating shaft part protrudes from the side of the cover part away from the inside of the handle, the cover part is provided with a first through hole, and the top pin is arranged in the first through hole.

[0016] In the above technical solution, the second opening is sealed by the cover part to give the first electric unlocking assembly and the second electric unlocking assembly stable working space, thereby improving the reliability of the intelligent handle lock. Meanwhile, the first through hole is arranged on the cover part, and the top pin is arranged in the first through hole, so that the top pin is movably arranged on the handle rotating shaft along the axial direction of the handle rotating shaft, and the structure is simple and easy to realize.

[0017] In some embodiments, along the circumferential direction of the handle rotating shaft, the locking groove has oppositely arranged first and second groove walls, and the distance between the first and second groove walls in the circumferential direction of the handle rotating shaft gradually increases from the base to the direction of the clutch piece.

[0018] In the above technical solution, the distance between the first and second groove walls in the circumferential direction of the handle rotating shaft gradually increases from the base to the direction of the clutch piece. When the operator rotates the handle to drive the handle rotating shaft to rotate, the handle rotating shaft can drive one end of the top pin to move relative to the first or second groove wall, so that the one end of the top pin is guided by the first or second groove wall to escape from the locking groove, thereby reducing the risk of emergency unlocking failure caused by the top pin being stuck in the locking groove.

[0019] In some embodiments, the first electric unlocking assembly comprises a clutch pin and a second driving module, the clutch pin is elastically connected with the base, the clutch piece is provided with a second through hole, the clutch pin is inserted into the second through hole to lock the base and the clutch piece, and the second driving module is used to drive the clutch pin to exit from the second through hole to unlock the clutch piece and the base.

[0020] In the above technical solution, the clutch pin is driven by the second driving module to exit from the second through hole to unlock the clutch piece and the base, and the structure is simple and easy to realize.

[0021] In some embodiments, the second driving module comprises a first motor, a rotating shaft and a clutch top pin, the rotating shaft is in transmission connection with the first motor, one end of the rotating shaft is provided with an arc-shaped slope surface, the clutch top pin is movably arranged in the handle along the axial direction of the handle rotating shaft, and the two ends of the clutch top pin are in abutment with the arc-shaped slope surface and the clutch pin respectively. The first motor drives the rotating shaft to rotate in a first direction to drive the clutch top pin to be inserted into the second through hole to push the clutch pin to exit from the second through hole. The first motor drives the rotating shaft to rotate in a second direction to release the restriction on the clutch top pin, the clutch pin is inserted into the second through hole to push the clutch top pin to exit from the second through hole, and the first direction is opposite to the second direction.

[0022] In the technical scheme, on one hand, the arc slope can convert the rotation of the rotating shaft into the linear motion of the clutch top pin; on the other hand, the arc slope can limit the positions of the clutch top pin and the clutch pin when the rotating shaft is in the locking state, and the structure is simple and easy to realize.

[0023] In some embodiments, the smart handle lock further comprises a first elastic limiting piece and a second elastic limiting piece, both of which are arranged on the handle rotating shaft, the inner periphery of the clutch plate is provided with a first limiting groove, and the inner periphery of the base is provided with a second limiting groove. When the smart handle lock is in the locking state, the first elastic limiting piece is matched with the first limiting groove, and the second elastic limiting piece is matched with the second limiting groove.

[0024] In the technical scheme, the first limiting piece and the second elastic limiting piece are arranged, and when the smart handle lock is in the locking state, the first elastic limiting piece is matched with the first limiting groove, and the second elastic limiting piece is matched with the second limiting groove. Therefore, the feedback when the first limiting piece and the second elastic limiting piece are matched with the first limiting groove and the second limiting groove respectively can confirm whether the smart handle lock is in the locking state, which is beneficial to improve the accuracy when the smart handle lock is switched to the locking state.

[0025] In some embodiments, the smart handle lock further comprises a battery located in the handle and electrically connected with the first electric unlocking assembly.

[0026] In the technical scheme, the battery is arranged in the smart handle lock, and the first electric unlocking assembly is provided with electric energy by the battery, so that the unlocking device does not need to provide electric energy to the smart handle lock in the normal unlocking process, thereby reducing the structural complexity of the unlocking device.

[0036] "Multiple" appearing in the application refers to two or more (including two).

[0037] The emergency unlocking assembly of the existing intelligent handle lock is usually a mechanical lock cylinder. The emergency unlocking lock cylinder is arranged at the handle handle. The conventional unlocking and emergency unlocking share the same locking member. The lock cylinder drives the locking member to move to realize the emergency unlocking. When the emergency unlocking is performed, the lock cylinder is directly driven by rotating the lock cylinder by inserting a key to drive the unlocking structure (such as a clutch top pin) to push the clutch structure, so that the lock is in an unlocked state. Therefore, the driving module needs to exert a sufficient driving force on the unlocking structure to enable the unlocking structure to push the clutch pin. For example, if the mechanical lock cylinder is replaced by an electronic lock cylinder, the driving module of the electronic lock cylinder needs to have a certain power, thereby being not conducive to reducing the size of the electronic lock cylinder, and thereby being not conducive to reducing the size of the emergency unlocking assembly.

[0038] Based on the above considerations, in order to reduce the size of the driving force required by the driving module when the electronic lock cylinder is switched between unlocking and locking, the present application provides an intelligent handle lock, comprising a handle assembly, a first electric unlocking assembly and a second electric unlocking assembly. The handle assembly comprises a handle, a handle shaft, a clutch plate, a base and a top pin. One end of the handle shaft is fixedly connected with the handle. The clutch plate is rotatably sleeved outside the handle shaft, and the side of the clutch plate facing the handle is provided with a locking groove. The base is sleeved outside the handle shaft and is fixedly connected with the external structure. The top pin is movably arranged on the handle shaft in the axial direction of the handle shaft. The first electric unlocking assembly is located in the handle, and is used for locking or unlocking the clutch plate and the base. The second electric unlocking assembly is located in the handle and comprises an electronic lock cylinder, a sliding block and a first elastic member. The side of the sliding block facing the handle shaft is provided with an abutting guide surface corresponding to one end of the top pin. In the radial direction of the handle shaft, the sliding block has a locking position and an unlocking position. The sliding block moves to the locking position under the action of the first elastic member and pushes the top pin to insert into the locking groove. The handle shaft rotates relative to the clutch plate to drive the top pin to move away from the locking groove and drive the sliding block to move to the unlocking position. The electronic lock cylinder is used to releasably lock the sliding block at the locking position to lock the handle shaft and the clutch plate.

[0039] In this type of smart handle lock, specifically, when the first electric unlocking component malfunctions or the battery is dead (at which point the clutch and base are locked), an external device (such as a mobile phone) can be connected to the second electric unlocking component. This causes the electronic lock cylinder in the second electric unlocking component to release the slider, thus freeing the slider from the locked position. The slider is then released from the locking groove only by the elastic force provided by the first elastic element, preventing the top pin from disengaging. At this point, rotating the handle can rotate the handle shaft, causing the top pin to disengage from the locking groove and slide one end of the top pin relative to the guide surface, driving the slider towards the unlocked position. This allows the handle shaft to rotate independently relative to the clutch and base, which in turn drives the unlocking mechanism (such as the bolt) of the smart handle lock, switching the smart handle lock from the locked to the unlocked state. When it is necessary to lock the smart handle lock in the locked state, rotating the handle can rotate the handle shaft, causing the top pin to align with the locking groove. The slider moves towards the locked position under the action of the first elastic element, pushing the top pin into the locking groove. Then connect the external device to the second electric unlocking component so that the electronic lock cylinder in the second electric unlocking component locks the slider in the locked position, thereby causing the slider to restrict the top pin to disengage from the locking groove, so that the handle shaft and clutch plate are locked, thereby locking the smart handle lock in the locked state.

[0040] Therefore, the electronic lock cylinder in the second electric unlocking assembly is only used to lock the slider in the locked position. When unlocking, the driving force for the top pin to disengage from the locking groove is provided by the operator. When locking, the driving force for the slider to return to the locked position and the driving force for the top pin to re-insert into the locking groove is provided by the first elastic element. The driving force required by the drive module of the electronic lock cylinder is relatively small, which helps to reduce the size of the electronic lock cylinder and thus helps to reduce the size of the smart handle lock.

[0041] The following detailed explanation of electronic locks, using a cabinet as an example with an external structure, is illustrated with reference to the attached diagram.

[0042] Please refer to Figures 1-8 , Figure 1 This is a schematic diagram of the structure of an electronic lock provided in some embodiments of this application. Figure 2 This is an exploded view of the structure of an electronic lock provided in some embodiments of this application. Figure 3 This is an exploded view of the structure of the handle assembly 100 provided in some embodiments of this application. Figure 4 The electronic lock provided in some embodiments of this application, when the slider 320 is in the locked position, along Figure 1 The sectional view obtained by cutting along the AA path. Figure 5 for Figure 4 A magnified view of a section at point C. Figure 6 The electronic lock provided in some embodiments of this application, when the slider 320 is in the unlocked position, along Figure 1a sectional view obtained by cutting along the A-A path, Figure 7 for Figure 6 a local enlarged view at E, Figure 8 is a structural exploded view of a second electric unlocking assembly 300 provided for some embodiments of the present application. The embodiments of the present application provide a smart handle lock 1000, which includes a handle assembly 100, a first electric unlocking assembly 200 and a second electric unlocking assembly 300. The handle assembly 100 includes a handle 10, a handle shaft 20, a clutch plate 30, a base 40 and a top pin 50. One end of the handle shaft 20 is fixedly connected with the handle 10. The clutch plate 30 is rotatably sleeved outside the handle shaft 20, and a locking groove 31 is arranged on the side of the clutch plate 30 facing the handle 10. The base 40 is sleeved outside the handle shaft 20 and fixedly connected with an external structure. The top pin 50 is movably arranged in the handle 10 along the axial direction X of the handle shaft. The first electric unlocking assembly 200 is located in the handle 10, and is used for locking or unlocking the clutch plate 30 and the base 40. The second electric unlocking assembly 300 is located in the handle 10, and includes an electronic lock cylinder 310, a sliding block 320 and a first elastic member 330. The side of the sliding block 320 facing the handle shaft 20 is provided with an abutting guide surface 320A abutting with one end of the top pin 50. Along the radial direction Y of the handle shaft, the sliding block 320 has a locking position and an unlocking position. The sliding block 320 moves to the locking position under the action of the first elastic member 330, and pushes the top pin 50 to extend out of the handle 10 and insert into the locking groove 31. The handle shaft 20 rotates relative to the clutch plate 30 to drive the top pin 50 to move out of the locking groove 31, and drive the sliding block 320 to move to the unlocking position. The electronic lock cylinder 310 has a locking state of locking the sliding block 320 at the locking position to lock the handle shaft 20 and the clutch plate 30, and an unlocking state of releasing the sliding block 320.

[0043] The handle 10 is a structural member in the handle assembly 100 for an operator to hold and apply an external force. Understandably, the handle 10 can have a hollow structure to provide installation space for other structural members. Exemplarily, please refer to Figure 2 The handle 10 has an accommodation cavity inside, wherein the first electric unlocking assembly 200 and the second electric unlocking assembly 300 are located in the accommodation cavity.

[0044] The external structure can be a house door, a cabinet door or a power cabinet door, etc. Next, the house door is taken as an example for description. The handle shaft 20 is a structural member for the handle assembly 100 to drive other structural members (such as a lock tongue 20A) in the handle assembly 100 to rotate to unlock or lock the house door.

[0045] It can be understood that when the intelligent handle lock 1000 is installed on the house door, the whole handle 10 and the part of the handle shaft 20 are located on the outside of the house door, and the part of the handle shaft 20 is located on the inside of the house door for installing other structural members (such as the lock tongue 20A) in the handle assembly 100. The operator rotates the handle 10 to drive the handle shaft 20 to rotate, thereby driving other structural members (such as the lock tongue 20A) in the handle assembly 100 to contact or separate from the matching member of the door frame, so that the house door is opened or locked.

[0046] In some embodiments, the handle assembly 100 further comprises a lock tongue 20A and a mounting screw 20B, the lock tongue 20A is connected with the end of the handle shaft 20 located on the inside of the house door through the mounting screw 20B. The lock tongue 20A is located on the inside of the house door, when the lock tongue 20A contacts with the matching member in the door frame, the house door is locked, when the lock tongue 20A rotates, and the position of the lock tongue 20A is misaligned with the matching member, the house door is unlocked.

[0047] The clutch plate 30 is a structural member rotatably sleeved outside the handle shaft 20 in the handle assembly 100.

[0048] The base 40 is a component fixedly connected with the house door in the handle assembly 100. In some embodiments, the handle assembly 100 further comprises a fixing nut 42 and a fixing seat 41, the base 40 is sleeved outside the handle shaft 20, sequentially passes through the fixing seat 41 on the house door, the fixing nut 42 is threadedly connected with the end of the base 40 passing through the house door, the fixing nut 42 abuts against the inner surface of the house door through the lock washer, and the base 40 presses the fixing seat 41 against the outer surface of the house door, so as to fix the handle assembly 100 to the house door.

[0049] In some embodiments, the end surface of the base 40 facing the clutch plate 30 abuts against the clutch plate 30, and the end surface of the clutch plate 30 facing the handle 10 abuts against the stepped surface on the handle shaft 20.

[0050] The top pin 50 is a pin-shaped structure movably arranged on the handle 10 along the axial direction X of the handle shaft.

[0051] In some embodiments, the first electric unlocking assembly 200 can be a solenoid, and the base 40 and the clutch plate 30 are provided with through holes, and the telescopic end of the first electric unlocking assembly 200 sequentially passes through the through hole on the base 40 and the through hole on the clutch plate 30, so that the clutch plate 30 cannot rotate relative to the base 40 alone.

[0052] During normal use, commands can be sent to the first electric unlocking component 200 via external devices (such as mobile phones) through wireless transmission methods such as Bluetooth. This causes the first electric unlocking component 200 to unlock the clutch plate 30 and the base 40, allowing the handle shaft 20 to rotate relative to the base 40, thereby facilitating the rotation of the handle shaft 20 to the locking tongue 20A. This allows the smart handle lock 1000 to switch between the unlocked and locked states. Alternatively, the first electric unlocking component 200 can lock the base 40 and the clutch plate 30, preventing the handle shaft 20 from rotating relative to the base 40. In this case, the second electric unlocking component 300 locks the slider 320 in the locked position, thus locking the handle shaft 20 and the clutch plate 30 and fixing the smart handle lock 1000 in the locked state.

[0053] In some embodiments, please refer to Figure 1 The smart handle lock 1000 also includes a battery 400, which is disposed inside the handle 10 and electrically connected to the first electric unlocking component 200. The smart handle lock 1000 may also include a Bluetooth system, which is electrically connected to the first electric unlocking component 200. The Bluetooth system is used to receive external signals so that the first electric unlocking component 200 locks or unlocks the base 40 and the clutch plate 30.

[0054] In some embodiments, please refer to Figure 2 The smart handle lock 1000 also includes a wake-up module 500, which includes an electronic control board 510 and a button 520. The electronic control board 510 is equipped with a Bluetooth system. The wake-up module 500 is located inside the handle 10. The battery 400 is connected to the button 520 through the electronic control board 510. The button 520 is exposed to the outside through a through hole on the side of the handle 10 away from the base 40.

[0055] Specifically, the lock's Bluetooth system is activated by button 520, the indicator light illuminates, and the mobile terminal communicates with the lock to send an unlocking command, energizing the first electric unlocking component 200 inside the handle 10, thereby unlocking the base 40 and the clutch plate 30. This eliminates the need for the first electric unlocking component to be constantly powered, reducing the energy consumption of the battery 400.

[0056] The second electric unlocking component 300 is a component used for emergency unlocking in the smart handle lock 1000. The electronic lock cylinder 310 is a structural component that locks the slider 320 in the locked position.

[0057] The slider 320 is a structural component that is movably disposed within the handle 10 along the radial Y direction of the handle rotation axis. For example, the slider 320 is provided with second protrusions 322 on both sides in the width direction, and the handle 10 is provided with a sliding groove extending radially Y along the handle rotation axis, and the second protrusions 322 are slidably disposed within the sliding groove.

[0058] For example, the guide surface 320A is disposed on the side of the slider 320 facing the handle shaft 20, and the distance between the guide surface 320A and the axis of the handle shaft 20 gradually increases along the direction from the base 40 to the clutch plate 30.

[0059] The first elastic element 330 can be a spring or a rubber structural element. For example, the slider 320 is provided with a first protrusion 321 on the side away from the handle shaft 20 along the radial Y of the handle shaft. The first elastic element 330 is sleeved on the first protrusion 321, and the other end of the first elastic element 330 abuts against the handle 10.

[0060] In some embodiments, please refer to Figure 8 The second electric unlocking assembly 300 also includes a first bracket 340, an electronic lock cylinder 310, a slider 320 and a first elastic element 330, all located within the first bracket 340. The slider 320 is disposed within the first bracket 340 in a radial Y-axis manner along the handle shaft, and one end of the top pin 50 is located within the first bracket 340.

[0061] Specifically, when the first electric unlocking component 200 malfunctions or the battery 400 is depleted (at which point the clutch plate 30 and base 40 are locked), an external device (such as a mobile phone) can be connected to the second electric unlocking component 300. This allows the electronic lock cylinder 310 in the second electric unlocking component 300 to release the slider 320, thus freeing the slider 320 from the locked position. Consequently, the slider 320 is only restrained by the elastic force provided by the first elastic element 330, causing the top pin 50 to disengage from the locking groove 31. At this time, rotating the handle 10 can drive the handle shaft 20 to rotate, causing the top pin 50 to disengage from the locking groove 31 and allowing one end of the top pin 50 to slide relative to the guide surface 320A, thereby driving the slider 320 to move towards the unlocked position. This allows the handle shaft 20 to rotate independently relative to the clutch plate 30 and base 40, which in turn drives the unlocking mechanism (such as the latch 20A) of the smart handle lock 1000 to rotate, allowing the smart handle lock 1000 to switch between the unlocked and locked states. When the smart handle lock 1000 needs to be locked, the handle 10 can be rotated to rotate the handle shaft 20, thereby aligning the top pin 50 with the locking groove 31. The slider 320 moves towards the locked position under the action of the first elastic element 330, pushing the top pin 50 into the locking groove 31. Then, an external device is connected to the second electric unlocking assembly 300, so that the electronic lock cylinder 310 in the second electric unlocking assembly 300 locks the slider 320 in the locked position, thereby preventing the top pin 50 from disengaging from the locking groove 31, thus locking the handle shaft 20 and the clutch plate 30, thereby locking the smart handle lock 1000 in the locked state.

[0062] For example, one end of the top pin 50 inserted into the locking groove 31 can be a hemisphere, and the radius of the hemisphere is greater than the groove depth of the locking groove 31.

[0063] In this embodiment, the electronic lock cylinder 310 in the second electric unlocking assembly 300 is only used to lock the slider 320 in the locked position. When unlocking, the driving force for the top pin 50 to disengage from the locking groove 31 is provided by the operator. When locking, the driving force for the slider 320 to return to the locked position and for the top pin 50 to re-insert into the locking groove 31 is provided by the first elastic element 330. The driving force required by the driving module of the electronic lock cylinder 310 is relatively small, which helps to reduce the size of the electronic lock cylinder 310 and thus helps to reduce the size of the smart handle lock 1000.

[0064] Please refer to Figures 4-7 According to some embodiments of this application, along the axial direction X of the handle shaft, the slider 320 has a receiving groove 320B on the side facing the electronic lock cylinder 310. The electronic lock cylinder 310 includes a first drive module 314 and a locking block 316. When the electronic lock cylinder 310 is in the locked state, the first drive module 314 drives the locking block 316 to insert into the receiving groove 320B to lock the slider 320 in the locked position; when the electronic lock cylinder 310 is in the unlocked state, the first drive module 314 drives the locking block 316 to exit the receiving groove 320B.

[0065] The first drive module 314 is a component in the electronic lock cylinder 310 that drives the locking block 316 to move. For example, the first drive module 314 can be a solenoid. The first drive module 314 is used to drive the locking block 316 to move so that the locking block 316 switches between inserting into the receiving groove 320B and exiting the receiving groove 320B.

[0066] In this embodiment, the locking block 316 moves along the axial direction X of the handle shaft to insert into or retract from the receiving groove 320B. When the slider 320 tends to move towards the unlock position, the groove wall of the receiving groove 320B abuts against the locking block 316 along the radial direction Y of the handle shaft. This causes the driving force applied by the slider 320 to the locking block 316 to be perpendicular to the direction in which the first drive module 314 drives the locking block 316 to move. This further reduces the driving force required by the first drive module 314 when the electronic lock cylinder 310 locks the slider 320, reduces the power requirement of the first drive module 314, and thus helps to reduce the size of the first drive module 314. This, in turn, helps to further reduce the size of the electronic lock cylinder 310 and the second electric unlocking component 300, and further helps to further reduce the size of the smart handle lock 1000.

[0067] Please refer to Figure 9 , Figure 9This is a cross-sectional view of an electronic lock cylinder 310 provided in some embodiments of this application. According to some embodiments of this application, the electronic lock cylinder 310 includes a housing 311, a circuit control module 312 disposed within the housing 311, a Type-C male connector 313, a first drive module 314, a transmission rod 315, and a first spring 317. One end of the Type-C male connector 313 extends out of the housing 311 and extends out of the handle 10, while the other end is connected to the circuit control module 312. The first drive module 314 is drively connected to the transmission rod 315. A locking block 316 is movably sleeved on the transmission rod 315. When the electronic lock cylinder 310 is in the locked state, the locking block 316 extends out of the housing 311; when the electronic lock cylinder 310 is in the unlocked state, the locking block 316 retracts into the housing 311, and an accommodating cavity 3161 is formed inside the locking block 316. The first spring 317 is disposed within the accommodating cavity 3161 and sleeved on the transmission rod 315. A first limiting protrusion 3151 is provided on the outer circumferential surface of the transmission rod 315, and the first limiting protrusion 3151 passes between the two turns of the first spring 317. The first driving module 314 drives the transmission rod 315 to rotate forward and backward, so that the transmission rod 315 pushes the locking block 316 out of the outer shell 311 and retract into the outer shell 311 through the first spring 317.

[0068] The outer casing 311 is a shell-like structure in the electronic lock cylinder 310 used to house other mechanical components. Exemplarily, the outer casing 311 can be made of metal, plastic, or ceramic.

[0069] The circuit control module 312 is structured to identify external devices and electrically connect the Type-C male connector 313 and the first drive module 314.

[0070] The Type-C male connector 313 (Type-C Plug) is the plug part of the USB Type-C interface. It is the end that is inserted into the connector and is used to mate with the Type-C female connector on an external device.

[0071] For example, the external device can be a mobile phone or a Bluetooth electronic key.

[0072] In some embodiments, the external device is a mobile phone. The mobile phone is directly inserted into the Type-C male connector 313. After authorization by the mobile phone APP, communication is matched, power is supplied to the first drive module 314, and the electronic lock cylinder 310 is unlocked.

[0073] In some embodiments, the external device is a Bluetooth electronic key. The Bluetooth electronic key is inserted into the Type-C male connector 313. The Bluetooth electronic key has unlocking permissions that match the circuit control module 312 of the electronic lock cylinder 310. Communication is matched, power is supplied to the first drive module 314, and the electronic lock cylinder 310 is unlocked.

[0074] In some embodiments, the external device is a Bluetooth electronic key. The Bluetooth electronic key is inserted into the Type-C male connector 313. The Bluetooth electronic key connects to a mobile APP via Bluetooth. After authorization by the mobile APP, the Bluetooth electronic key supplies power to the first drive module 314 to unlock the electronic lock cylinder 310.

[0075] The first drive module 314 can be a component that drives the transmission rod 315 to rotate. For example, the first drive module 314 can be a solenoid. It can be understood that the first drive module 314 can directly drive the transmission rod 315 to rotate, or the first drive module 314 can indirectly drive the transmission rod 315 to rotate through a transmission mechanism.

[0076] The first drive module 314 also includes a second motor 3143, a drive gear 3141, and a driven gear 3142; the drive gear 3141 is mounted on the output shaft of the second motor 3143; the driven gear 3142 is mounted on the transmission rod 315 and meshes with the drive gear 3141.

[0077] The locking block 316 is a structure that can be movably mounted on the transmission rod 315.

[0078] The first limiting protrusion 3151 is a protruding structure that protrudes from the periphery of the transmission rod 315.

[0079] In some embodiments, a positioning hole is provided on the transmission rod 315, which extends radially through the transmission rod 315. A positioning pin is provided in the positioning hole, and both ends of the positioning pin protrude from the periphery of the transmission rod 315 to form a first limiting protrusion 3151.

[0080] Understandably, the two ends of the first spring 317 are configured to move along the axis of the receiving cavity 3161.

[0081] Since the first spring 317 is sleeved on the transmission rod 315 and located inside the accommodating cavity 3161, and the first limiting protrusion 3151 passes between the two spiral turns of the first spring 317, when the first limiting protrusion 3151 rotates with the transmission rod 315, the first limiting protrusion 3151 will move along the spiral of the first spring 317, thereby causing the first spring 317 to move along the transmission rod 315 and to abut against the two walls of the accommodating cavity 3161 in its direction of movement. This allows the first spring 317 to provide elastic force to the accommodating cavity 3161, thereby driving the locking block 316 to switch between extending out of the outer casing 311 and retracting into the outer casing 311.

[0082] Specifically, an external device (such as a mobile phone) supplies power to the first drive module 314 via a Type-C male connector 313. When retracted into the housing 311, the portion of the first spring 317 located between the wall of the accommodating cavity 3161 near the slider 320 and the first limiting protrusion 3151 reaches its maximum length in the extending direction of the first spring 317. This allows the portion of the first spring 317 to apply an elastic force to the wall of the accommodating cavity 3161 near the slider 320, causing the locking block 316 to retract into the housing 311. When block 316 extends out of outer casing 311, the first drive module 314 drives transmission rod 315 to rotate forward, causing the length of the first spring 317 in the extending direction of the portion of the first spring 317 located in the accommodating cavity 3161 near the wall of slider 320 and the first limiting protrusion 3151 to gradually decrease, and causing the length of the first spring 317 in the extending direction of the portion of the first spring 317 located in the accommodating cavity 3161 away from the wall of slider 320 and the first limiting protrusion 3151 to gradually increase. On the one hand, this causes the first spring... The portion of spring 317 located between the wall of the receiving cavity 3161 near the slider and the first limiting protrusion 3151 gradually decreases the elastic force provided to the wall of the receiving cavity 3161 near the slider. On the other hand, the portion of spring 317 located between the wall of the receiving cavity 3161 away from the slider 320 and the first limiting protrusion 3151 provides a gradually increasing elastic force to the wall of the receiving cavity 3161 away from the slider 320, thereby driving the locking block 316 to extend out of the housing 311. When the locking block 316 extends out of the housing 311 and the first driving... When module 314 tends to continue rotating, transmission rod 315 continues to rotate in the forward direction, so that the first limiting protrusion 3151 continues to move along the extension direction of the first spring 317. This causes the length of the portion of the first spring 317 located between the wall of the accommodating cavity 3161 away from the slider 320 and the first limiting protrusion 3151 in the extension direction of the first spring 317 to further increase, so as to provide greater elastic force to the wall of the accommodating cavity 3161 away from the slider 320, thereby enabling the first drive module 314 to continue rotating.

[0083] In this embodiment, when the locking block 316 switches to extend out of the housing 311 or retract into the housing 311 and the first drive module 314 has a tendency to continue rotating, the first drive module 314 can continue to rotate, reducing the probability of the first drive module 314 stalling, thereby reducing the risk of damage to the first drive module 314.

[0084] Please refer to Figure 10According to some embodiments of this application, the handle assembly 100 further includes a dust cover 60, which is slidably disposed on the side of the handle 10 away from the base 40 along the radial Y of the handle axis. The side of the handle 10 away from the base 40 is provided with a first opening 10A for one end of the Type-C male connector 313 to extend out. The dust cover 60 has a closed position for closing the first opening 10A and an open position for opening the first opening 10A.

[0085] In some embodiments, the handle 10 includes a connecting portion 12 and a grip portion 11. One end of the connecting portion 12 is connected to and coaxially disposed with the handle shaft 20. The connecting portion 12 has a cavity for accommodating a first electric unlocking component 200 and a second electric unlocking component 300. A first opening 10A is disposed on the end wall of the connecting portion 12 away from the handle shaft 20. The grip portion 11 is connected to the other end of the connecting portion 12 and extends radially Y along the handle shaft. The outer surface of the grip portion 11 is provided with a sliding groove extending along the extending direction of the grip portion 11. A dust cover 60 is disposed on the grip portion 11. The portion of the dust cover 60 is located within the sliding groove and can slide along the sliding groove.

[0086] In this embodiment, by setting the dust cover 60 to a closed position with a closed opening, the risk of external dust falling on the Type-C male connector 313 can be reduced when the dust cover 60 is not in use. At the same time, by setting the dust cover 60 to an open position with the first opening 10A open, the risk of the dust cover 60 interfering with the connection between the external device and the Type-C male connector 313 is reduced.

[0087] Please refer to Figure 11 , Figure 11 This is a schematic diagram of the assembly of the handle 10 and the handle shaft 20 provided in some embodiments of this application. According to some embodiments of this application, the handle shaft 20 includes a cover portion 21 and a shaft portion 22. The handle 10 has a second opening 10B on the side facing the base 40. The cover portion 21 blocks the second opening 10B. The shaft portion 22 protrudes from the cover portion 21 on the side away from the inside of the handle 10. The cover portion 21 has a first through hole 21A, and a top pin 50 passes through the first through hole 21A.

[0088] The cover portion 21 is the part of the handle shaft 20 used to seal the second opening 10B. In some embodiments, the cover portion 21 and the second opening 10B are sealed together by a seal 13, which may be, but is not limited to, a sealing ring, a sealing gasket, or a sealant.

[0089] The pivot portion 22 is the part of the handle pivot 20 that passes through the door. For example, the cover portion 21 protrudes from the periphery of the pivot portion 22 to form a stepped surface on the handle pivot 20 for abutting against the clutch plate 30.

[0090] In this embodiment, the second opening 10B is blocked by the cover portion 21 to provide a stable working space for the first electric unlocking component 200 and the second electric unlocking component 300, thereby improving the reliability of the smart handle lock 1000. At the same time, by providing a first through hole 21A in the cover portion 21, the top pin 50 is inserted into the first through hole 21A, so that the top pin 50 is movably set on the handle shaft 20 along the axial direction X of the handle shaft. The structure is simple and easy to implement.

[0091] Please refer to Figure 12 According to some embodiments of this application, along the circumferential direction of the handle shaft 20, the locking groove 31 has a first groove wall 31A and a second groove wall 31B disposed opposite to each other. In the direction from the base 40 to the clutch plate 30, the distance between the first groove wall 31A and the second groove wall 31B in the circumferential direction of the handle shaft 20 gradually increases.

[0092] In this embodiment, the distance between the first groove wall 31A and the second groove wall 31B in the circumferential direction of the handle shaft 20 gradually increases from the base 40 to the clutch plate 30. When the operator rotates the handle 10 to drive the handle shaft 20 to rotate, the handle shaft 20 can drive one end of the top pin 50 to move relative to the first groove wall 31A or the second groove wall 31B. This guides one end of the top pin 50 out of the locking groove 31 through the first groove wall 31A or the second groove wall 31B, reducing the risk of the top pin 50 getting stuck in the locking groove 31 and causing emergency unlocking failure.

[0093] Please refer to Figures 12-16 According to some embodiments of this application, Figure 13 The electronic lock provided in some embodiments of this application locks the base 40 and the clutch plate 30 along the clutch pin 210. Figure 1 The cross-sectional view obtained by cutting along the BB path. Figure 14 for Figure 13 A magnified view of a section at point F. Figure 15 The electronic lock provided in some embodiments of this application, when the clutch pin 210 unlocks the base 40 and the clutch plate 30, moves along... Figure 1 The cross-sectional view obtained by cutting along the BB path. Figure 16 for Figure 15 A partial enlarged view of point G in the middle. The first electric unlocking assembly 200 includes a clutch pin 210 and a second drive module 220. The clutch pin 210 is elastically connected to the base 40. The clutch plate 30 is provided with a second through hole 32. The clutch pin 210 is inserted into the second through hole 32 to lock the base 40 and the clutch plate 30. The second drive module 220 is used to drive the clutch pin 210 out of the second through hole 32 to unlock the clutch plate 30 and the base 40.

[0094] The clutch pin 210 is a pin-shaped structure that is elastically connected to the base 40. When a portion of the clutch pin 210 is inserted into the second through hole 32, the base 40 is connected to the clutch plate 30 through the clutch pin 210, thereby preventing the clutch plate 30 from rotating relative to the base 40; when the clutch pin 210 is disengaged from the second through hole 32, the clutch plate 30 can rotate relative to the base 40.

[0095] In some embodiments, please refer to Figures 13-16 The handle assembly 100 also includes a clutch spring 211. A first mounting hole 40A is provided on the end face of the base 40 facing the clutch plate 30. The clutch spring 211 is located within the first mounting hole 40A, with one end connected to the bottom wall of the first mounting hole 40A and the other end connected to the clutch pin 210. The clutch pin 210 is retractably disposed within the mounting hole. The clutch spring 211 provides elastic force to the clutch pin 210 so that, when the mounting hole is aligned with the second through hole 32, a portion of the clutch pin 210 can be inserted into the second through hole 32.

[0096] Understandably, the axis of the clutch shaft is offset relative to the axis of the base 40, and the axis of the second through hole 32 is offset relative to the axis of the clutch plate 30.

[0097] The second drive module 220 is a component in the electronic lock cylinder 310 that drives the clutch pin 210 to move. For example, the second drive module 220 can be a solenoid, with its telescopic end abutting against the clutch pin 210, and the telescopic end extending out to drive the clutch pin 210 out of the second through hole 32.

[0098] In this embodiment, the clutch pin 210 is driven to disengage from the second through hole 32 by the second drive module 220 to unlock the clutch plate 30 and the base 40. The structure is simple and easy to implement.

[0099] Please refer to Figures 12-17Figure 17 is an exploded view of the structure of the second drive module 220 provided in some embodiments of this application. According to some embodiments of this application, the second drive module 220 includes a first motor 221, a rotating shaft 222, and a clutch top pin 223. The rotating shaft 222 is drivenly connected to the first motor 221, and one end of the rotating shaft 222 is provided with an arc-shaped slope 222A. Exemplarily, along the first direction, the distance between the arc-shaped slope 222A and the clutch plate 30 gradually increases along the axial direction X of the handle shaft. The clutch top pin 223 is movably disposed in the handle 10 along the axial direction X of the handle shaft, and both ends of the clutch top pin 223 abut against the arc-shaped slope 222A and the clutch pin 210, respectively. The first motor 221 drives the rotating shaft 222 to rotate along the first direction, so as to drive the clutch top pin 223 to insert into the second through hole 32 to push the clutch pin 210 out of the second through hole 32. The first motor 221 drives the rotating shaft 222 to rotate in the second direction to release the restriction on the clutch top pin 223. The clutch pin 210 is inserted into the second through hole 32 to push the clutch top pin 223 out of the second through hole 32. The first direction and the second direction are opposite.

[0100] The rotating shaft 222 is a structural component used to drive the clutch top pin 223 to move along the axial X-axis of the handle rotating shaft.

[0101] The clutch top pin 223 is a pin-shaped structure that is movably disposed in the handle 10 along the axial direction X of the handle shaft. For example, the cover portion 21 is provided with a third through hole 21B, and the clutch top pin 223 passes through the third through hole 21B.

[0102] In some embodiments, please refer to Figure 17 The second drive module 220 also includes a second bracket 224. The first motor 221, the rotating shaft 222 and the clutch top pin 223 are all located in the second bracket 224. The end of the second bracket 224 near the cover part 21 is provided with a through hole corresponding to the third through hole 21B, and the clutch top pin 223 passes through the through hole.

[0103] In this embodiment, on the one hand, by setting the arc-shaped slope 222A, the rotation of the rotating shaft 222 can be converted into the linear motion of the clutch top pin 223; on the other hand, by setting the arc-shaped slope 222A, the position of the clutch top pin 223 and the clutch pin 210 can be restricted when the rotating shaft 222 is in the locked state, which is simple and easy to implement.

[0104] Please refer to Figure 18 , Figure 18 for Figure 4A partial enlarged view at point D. According to some embodiments of this application, the smart handle lock 1000 further includes a first elastic limiting member 22A and a second elastic limiting member 22B. Both the first elastic limiting member 22A and the second elastic limiting member 22B are disposed on the handle shaft 20. A first limiting groove 33 is provided on the inner circumference of the clutch plate 30, and a second limiting groove 40B is provided on the inner circumference of the base 40. When the smart handle lock 1000 is in the locked state, the first elastic limiting member 22A engages with the first limiting groove 33, and the second elastic limiting member 22B engages with the second limiting groove 40B.

[0105] For example, both the first elastic limiting member 22A and the second elastic limiting member 22B are ball spring pins.

[0106] In this embodiment, by providing a first elastic limiting member 22A and a second elastic limiting member 22B, and when the smart handle lock 1000 is in the locked state, the first elastic limiting member 22A engages with the first limiting groove 33, and the second elastic limiting member 22B engages with the second limiting groove 40B. This allows for feedback on whether the smart handle lock 1000 is in the locked state through the engagement of the first elastic limiting member 22A and the second elastic limiting member 22B with the first limiting groove 33 and the second limiting groove 40B, respectively, thus improving the accuracy of the smart handle lock 1000 when switching to the locked state.

[0107] Please refer to Figure 4 and Figure 6 According to some embodiments of this application, the smart handle lock 1000 also includes a battery 400 located within the handle 10 and electrically connected to the first electric unlocking assembly 200.

[0108] In some embodiments, the grip portion 11 has a mounting port on the side facing the door, through which the battery 400 is installed in the grip portion 11. The handle assembly 100 also includes a battery cover 70 for sealing the mounting port.

[0109] In this embodiment, by setting a battery 400 inside the smart handle lock 1000 and supplying power to the first electric unlocking component 200 through the battery 400, the unlocking device does not need to supply power to the smart handle lock 1000 during normal unlocking, which helps to reduce the structural complexity of the unlocking device.

[0110] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0111] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
