Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lock, in particular to an emergency unlocking structure and an intelligent lock. BACKGROUND

[0002] A lock is a device used to protect property, premises, or information security. The function of the lock is to provide a means of limiting and controlling access, ensuring that only authorized individuals or individuals can use or enter the protected area or item. Locks can be used in various applications, such as home door locks, office door locks, vehicle locks, safe locks, computer password locks, etc.

[0003] In the prior art, intelligent locks are becoming the choice of more and more owners. The intelligent lock uses fingerprint, Bluetooth, password and other non-mechanical key methods to unlock, which brings great convenience to the user, and its security is also greatly improved compared with traditional mechanical locks. However, when the lock fails, the lock cannot be opened, and the user usually uses a spare mechanical key to open the lock, but the user generally does not carry a mechanical key or places the mechanical key in a spare location which is not convenient to retrieve, resulting in the user being unable to perform emergency unlocking. SUMMARY

[0004] Therefore, the present application provides an emergency unlocking structure and an intelligent lock to solve the problem that the user generally does not carry a mechanical key or places the mechanical key in a spare location which is not convenient to retrieve, resulting in the user being unable to perform emergency unlocking.

[0005] In a first aspect, the present application provides an emergency unlocking structure, comprising: a housing; a lock barrel arranged in the housing; a lock shell fixedly arranged in the housing and coaxially sleeved on the lock barrel; a rotating seat rotatably arranged in the housing and sleeved on the lock barrel, the rotating seat being arranged in the axial direction of the lock barrel and spaced apart from the lock shell; a push piece fixedly connected to the rotating seat; a transmission seat rotatably arranged in the housing and sleeved on the rotating seat, the lock barrel, the rotating seat and the transmission seat sequentially forming a first mounting hole, a second mounting hole and a third mounting hole; a control member rotatably arranged on the housing and located on one side of the transmission seat, the control member being in transmission connection with the transmission seat; a linkage assembly comprising a first linkage pin and a second linkage pin, the first linkage pin being adapted to move between the first mounting hole and the second mounting hole, and the second linkage pin being adapted to move between the second mounting hole and the third mounting hole, the linkage assembly having a first state and a second state, in the first state, the first linkage pin partially enters the second mounting hole, and the second linkage pin avoids the second mounting hole, in the second state, the second linkage pin partially enters the second mounting hole, and the first linkage pin avoids the second mounting hole, the control member being adapted to drive the transmission seat and the rotating seat to rotate; a driving mechanism acting on the linkage assembly and capable of driving the linkage assembly to switch between the first state and the second state.

[0006] Advantages:

[0007] In the case that the lock has an electronic failure and the user does not carry a mechanical key, the emergency unlocking structure of the present application controls the controller through a backup circuit, so that the driving mechanism switches the linkage assembly to the second state. In the second state, the first linkage pin avoids the second mounting hole to release the linkage between the lock cylinder and the rotating seat, so that the rotating seat can rotate relative to the lock cylinder. At the same time, the second linkage pin partially enters the second mounting hole to enable the transmission seat to move synchronously with the rotating seat. The operator can drive the operating member to rotate the rotating seat and the paddle with the help of the transmission seat, thereby completing unlocking. Thus, the user can also perform emergency unlocking without carrying a mechanical key, which can improve user experience.

[0008] When the driving mechanism does not receive the control of the controller, the linkage assembly is in the first state, and the first linkage pin is between the first mounting hole and the second mounting hole, which can link the lock cylinder and the rotating seat to ensure that the lock shell can limit the lock cylinder, thereby preventing the lock cylinder from rotating without inserting a mechanical key into the keyhole and ensuring the safety of the emergency unlocking structure.

[0009] Since the operating member is arranged on one side of the transmission seat in the emergency unlocking structure of the present application, the operating member can be independently hinged to the shell and is not easy to interfere with other structures in the shell. The operating member can be arranged to rotate 360 degrees, which enables the emergency unlocking structure of the present application to be applied to various types of locks with different unlocking angles, thereby expanding the application range of the emergency unlocking structure of the present application.

[0010] In an alternative embodiment, the linkage assembly further comprises a first elastic member arranged in the first mounting hole and located on the side of the first linkage pin away from the second linkage pin. The first linkage pin is adapted to partially enter the second mounting hole under the pushing of the first elastic member.

[0011] Advantages:

[0012] By such an arrangement, in the state that the driving mechanism does not act on the linkage assembly, the first elastic member can support the linkage assembly in the first state through its own elastic support force, so that the lock cylinder and the rotating seat are linked to ensure that the lock cylinder can cooperate with the lock shell to limit the rotating seat, thereby ensuring the safety of the emergency unlocking structure.

[0013] In an alternative embodiment, the emergency unlocking structure further comprises a first anti-disengagement eave formed on the hole wall of the first mounting hole. The inner diameter of the first anti-disengagement eave is smaller than the maximum outer diameter of the first linkage pin.

[0014] Advantages:

[0015] The first anti-extrusion eaves can prevent the first linkage pin from being extruded out of the first mounting hole under the pushing of the first elastic member, so that the operation of the linkage assembly is more stable.

[0016] In an alternative embodiment, the linkage assembly further comprises:

[0017] a first abutting portion formed on the hole wall of the third mounting hole;

[0018] a second abutting portion formed on the second linkage pin;

[0019] a second elastic member sleeved on the second linkage pin, two ends of the second elastic member abutting against the first abutting portion and the second abutting portion respectively, and adapted to apply an elastic force to the second linkage pin in the direction close to the first linkage pin.

[0020] Advantages:

[0021] The second linkage pin can abut against the first linkage pin under the action of the second elastic member. By such arrangement, when the driving mechanism acts on the linkage assembly, the second linkage pin can enter into the second mounting hole while forcing the first linkage pin to be separated from the second mounting hole, thereby releasing the linkage between the lock barrel and the rotating seat.

[0022] When the linkage assembly loses the driving force of the driving mechanism, the first linkage pin can enter into the second mounting hole under the support of the first elastic member while forcing the second linkage pin to be separated from the second mounting hole, so as to realize the linkage between the lock barrel and the rotating seat and release the linkage between the transmission seat and the rotating seat.

[0023] In an alternative embodiment, the driving mechanism comprises:

[0024] a linear driving mechanism;

[0025] a push plate connected with the linear driving mechanism and arranged corresponding to the second linkage pin.

[0026] Advantages:

[0027] The push plate can be extended towards the second linkage pin under the driving of the linear driving mechanism, and the second linkage pin is forced to move close to the first linkage pin, so that the linkage assembly is switched from the first state to the second state.

[0028] In an alternative embodiment, an arc-shaped pushing surface is formed on the side of the push plate close to the transmission seat, and the center of the arc-shaped pushing surface is concentrically arranged with the center of the transmission seat when the linkage assembly is in the second state.

[0029] Advantages:

[0030] By so arranging, during rotation of the transmission seat, the arc-shaped pushing surface can always stably contact with the second linkage pin, and reliably limit the linkage assembly in the second state, thereby ensuring stable operation of the emergency unlocking structure.

[0031] In an alternative embodiment, the outer periphery of the transmission seat is formed with a first gear, and the outer periphery of the operating member is formed with a second gear, the first gear being engaged with the second gear.

[0032] Beneficial effects: the operating member and the transmission seat are drivingly connected through the first gear and the second gear, the transmission precision is high, and the operating member is not easy to slip off, and the transmission ratio between the operating member and the transmission seat can be adjusted by adjusting the tooth number ratio of the first gear and the second gear.

[0033] In an alternative embodiment, the operating member comprises:

[0034] a hinge shaft hingedly connected with the housing, the second gear being formed on the outer periphery of the hinge shaft;

[0035] a knob connected with the hinge shaft, the housing being provided with a clearance opening on the side away from the tab, the knob being arranged to pass through the clearance opening.

[0036] Beneficial effects:

[0037] By so arranging, the knob can be arranged on the side of the housing facing the user, so that the operator can easily pull out the knob without a mechanical key, and rotate the transmission seat through the knob, the structure is simple, and the operation is convenient.

[0038] In an alternative embodiment, the housing is provided with a knob limiting groove connected with the clearance opening, the third mounting hole being in communication with the second mounting hole when the knob is arranged in the knob limiting groove.

[0039] Beneficial effects:

[0040] By so arranging, the operator can put the knob back into the knob limiting groove after unlocking the emergency unlocking structure, so as to reset the transmission seat, and facilitate normal use of the emergency unlocking structure next time.

[0041] In a second aspect, the present application further provides an intelligent lock comprising:

[0042] a back plate;

[0043] the emergency unlocking structure provided in the first aspect of the present application is fixedly arranged on the back plate.

[0044] Beneficial effects:

[0045] The intelligent lock of the second aspect of the present application sets the emergency unlocking structure on the back plate. When the intelligent lock has an electronic failure and the user does not carry a mechanical key, the controller is controlled through a backup circuit (for example, the controller is connected through a mobile phone APP or a Bluetooth connection, etc.), so that the driving mechanism switches the linkage assembly to the second state. In the second state, the first linkage pin avoids the second mounting hole to release the linkage between the lock cylinder and the rotating seat, so that the rotating seat can rotate relative to the lock cylinder. At the same time, the second linkage pin partially enters the second mounting hole to enable the transmission seat to move synchronously with the rotating seat. The operator can drive the operating member to rotate the rotating seat and the paddle with the help of the transmission seat, and complete the unlocking.

[0046] The intelligent lock of the present application has simple structure and is convenient to use, and can bring better experience to the user. BRIEF DESCRIPTION OF DRAWINGS

[0067] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0068] The embodiments of the present application will be described below with reference to Figures 1 to 7 .

[0069] According to the embodiments of the present application, in one aspect, an emergency unlocking structure is provided, comprising a shell 1, a lock barrel 2, a lock shell 3, a rotating seat 4, a dial 5, a transmission seat 6, an operating member 7, a linkage assembly and a drive mechanism 9. The lock barrel 2 is arranged in the shell 1. The lock shell 3 is fixedly arranged in the shell 1 and coaxially sleeved on the lock barrel 2. The rotating seat 4 is rotatably arranged in the shell 1 and sleeved on the lock barrel 2. The rotating seat 4 is arranged in the axial direction of the lock barrel 2 and spaced from the lock shell 3. The dial 5 is fixedly connected to the rotating seat 4. The transmission seat 6 is rotatably arranged in the shell 1 and sleeved on the rotating seat 4. First, second and third mounting holes 201, 401 and 601 are formed in the lock barrel 2, the rotating seat 4 and the transmission seat 6, respectively.

[0070] The operating member 7 is rotatably arranged on the housing 1 and located at one side of the transmission seat 6. The operating member 7 is in transmission connection with the transmission seat 6. The linkage assembly includes a first linkage pin 801 and a second linkage pin 802. The first linkage pin 801 is adapted to move between the first mounting hole 201 and the second mounting hole 401. The second linkage pin 802 is adapted to move between the second mounting hole 401 and the third mounting hole 601. The linkage assembly has a first state and a second state. In the first state, the first linkage pin 801 partially enters the second mounting hole 401, and the second linkage pin 802 avoids the second mounting hole 401. In the second state, the second linkage pin 802 partially enters the second mounting hole 401, and the first linkage pin 801 avoids the second mounting hole 401. The operating member 7 is adapted to drive the transmission seat 6 and the rotating seat 4 to rotate. The driving mechanism 9 acts on the linkage assembly and can drive the linkage assembly to switch between the first state and the second state.

[0071] The emergency unlocking structure of the present application can switch the linkage assembly to the second state by the controller controlled by the standby circuit when the lock appears electronic failure and the user does not carry the mechanical key 11. In the second state, the first linkage pin 801 avoids the second mounting hole 401 to release the linkage between the lock cylinder 2 and the rotating seat 4, so that the rotating seat 4 can rotate relative to the lock cylinder. At the same time, the second linkage pin 802 partially enters the second mounting hole 401 to enable the transmission seat 6 to move synchronously with the rotating seat 4. The operator can drive the operating member to rotate the rotating seat 4 and the paddle 5 by the transmission seat 6, and complete unlocking. Thus, the user can also perform emergency unlocking without carrying the mechanical key, which can improve user experience.

[0072] When the driving mechanism is not controlled by the controller, the linkage assembly is in the first state, and the first linkage pin 801 is between the first mounting hole 201 and the second mounting hole 401, which can link the lock cylinder 2 with the rotating seat 4, ensure that the lock housing 3 can limit the lock cylinder 2, and avoid the lock cylinder 2 from rotating without inserting the mechanical key 11 into the keyhole, thereby ensuring the safety of the emergency unlocking structure.

[0073] The related technology provides an emergency unlocking structure, which is different from the emergency unlocking structure of the present application in that a limiting plate is fixedly arranged in the shell, the lock shell is fixedly connected to the limiting plate, the operating member is sleeved outside the lock shell and is rotationally connected to the limiting plate, and is adapted to rotate with the transmission seat under the action of external force. This makes it necessary to set a matching structure for rotationally connecting the operating member on the limiting plate, and a connecting structure for fixedly connecting the lock shell. However, the operating member will interfere with the connecting structure after rotating by a certain angle along the matching structure, thereby restricting the rotation angle of the operating member and limiting the application of some lock cores that need to be rotated by a large angle to be unlocked (for example, some lock cores need to be rotated by 360° or 720° to be unlocked) in the emergency unlocking structure, and the application range of the emergency unlocking structure is narrow.

[0074] In the emergency unlocking structure of the present application, the operating member 7 is arranged on one side of the transmission seat 6, so that the operating member 7 can be independently hinged to the shell 1 and is not easy to interfere with the shell 1 and other structures in the shell 1. The operating member 7 can freely rotate relative to the shell 1, which makes the emergency unlocking structure of the present application applicable to various unlocking angle locks (for example, locks that need to be rotated by 360° or 720° to be unlocked), thereby expanding the application range of the emergency unlocking structure of the present application.

[0075] The controller can include a programmable logic control component (such as a PLC or a CPU), a memory, and electronic elements connected to the programmable logic control component, which are well known to those skilled in the art and will not be described in detail here. The operator can use a mobile phone APP or other mobile terminal to communicate with the controller and control the controller through the backup circuit.

[0076] Preferably, the lock shell 3 is fixedly connected to one side of the shell 1 away from the paddle 5, and the rotating seat 4 is rotationally connected to the other side of the shell 1.

[0077] In one embodiment, as shown in Figure 1 and Figure 2 The linkage assembly further includes a first elastic member 803. The first elastic member 803 is arranged in the first mounting hole 201 and located on the side of the first linkage pin 801 away from the second linkage pin 802. The first linkage pin 801 is adapted to partially enter the second mounting hole 401 under the push of the first elastic member 803.

[0078] By so arranging, in the state that the driving mechanism 9 does not act on the linkage assembly, the first elastic member 803 can switch the linkage assembly to the first state by the elastic supporting force of itself. At this time, the first linkage pin 801 is between the first mounting hole 201 and the second mounting hole 401, and can link the lock cylinder 2 with the rotating seat 4, ensure that the lock shell 3 can limit the lock cylinder 2, avoid the rotation of the lock cylinder 2 in the case that the mechanical key 11 is not inserted into the key hole, and ensure the safety of the emergency unlocking structure.

[0079] Preferably but not limitedly, the first elastic member 803 is a spring, an elastic plunger, an elastic gasket or an elastic sleeve.

[0080] In an embodiment, the emergency unlocking structure further comprises a first anti-falling eaves 202. The first anti-falling eaves 202 is formed on the hole wall of the first mounting hole 201, and the inner diameter is smaller than the maximum outer diameter of the first linkage pin 801. The first anti-falling eaves 202 can prevent the first linkage pin 801 from falling out of the first mounting hole 201 under the push of the first elastic member 803, so that the operation of the linkage assembly is more stable.

[0081] In an embodiment, as shown in Figure 6 The third mounting hole 601 is formed on the protruding portion 603. By so arranging, the third mounting hole 601 has a large hole depth, which helps to ensure the stable cooperation between the second linkage pin 802 and the third mounting hole 601, and at the same time does not excessively increase the volume of the transmission seat 6, which helps to reduce the manufacturing cost of the transmission seat 6.

[0082] In an embodiment, the linkage assembly further comprises a first abutting portion 804, a second abutting portion 805 and a second elastic member 806. The first abutting portion 804 is formed on the hole wall of the third mounting hole 601. The second abutting portion 805 is formed on the second linkage pin 802. The second elastic member 806 is sleeved on the second linkage pin 802. The two ends of the second elastic member 806 respectively abut against the first abutting portion 804 and the second abutting portion 805, and are adapted to apply an elastic force to the second linkage pin 802 in the direction close to the first linkage pin 801. Preferably, the first abutting portion 804 comprises an abutting eaves formed on the hole wall of the third mounting hole 601, and the second abutting portion 805 comprises an axial flange formed on the outer periphery of the second linkage pin 802.

[0083] The second linkage pin 802 can abut against the first linkage pin 801 under the action of the second elastic member 806. By so arranging, when the driving mechanism 9 acts on the linkage assembly, the second linkage pin 802 can enter the second mounting hole 401 while forcing the first linkage pin 801 to disengage from the second mounting hole 401, thereby releasing the linkage between the lock cylinder 2 and the rotating seat 4.

[0084] When the linkage assembly loses the driving force of the driving mechanism 9, the first linkage pin 801 can enter into the second mounting hole 401 under the support of the first elastic member 803, while forcing the second linkage pin 802 to disengage from the second mounting hole 401, to realize the linkage between the lock cylinder 2 and the rotating seat 4, and to release the linkage between the transmission seat 6 and the rotating seat 4. The second elastic member 806 is preferably but not limited to a spring, an elastic plunger, an elastic gasket, or an elastic sleeve.

[0085] In an embodiment, the driving mechanism 9 includes a second elastic member 806 and a push plate 902. The push plate 902 is connected to the linear driving mechanism 9 and is arranged corresponding to the second linkage pin 802. The push plate 902 can be driven by the linear driving mechanism 9 to extend towards the second linkage pin 802, and to make the second linkage pin 802 move close to the first linkage pin 801, so as to switch the linkage assembly from the first state to the second state.

[0086] The linear driving mechanism 9 can be selected as a device capable of outputting linear motion, such as a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, or a combination of a motor and a rack and pinion. For example, in the embodiment, the linear driving mechanism 9 is a motor, which is fixedly arranged in the housing 1.

[0087] In an embodiment, an arc-shaped pushing surface 903 is formed on the side of the push plate 902 close to the transmission seat 6. When the linkage assembly is in the second state, the center of the arc-shaped pushing surface 903 is concentrically arranged with the center of the transmission seat 6. By such arrangement, the arc-shaped pushing surface 903 can always stably contact the second linkage pin 802 during the rotation of the transmission seat 6, and reliably position the linkage assembly in the second state, to ensure the stable operation of the emergency unlocking structure.

[0088] In an embodiment, as shown in Figure 3 and Figure 4 The outer periphery of the transmission seat 6 is formed with a first gear 602. The outer periphery of the operating member 7 is formed with a second gear 702, and the first gear 602 is engaged with the second gear 702. The first gear 602 and the second gear 702 are drivingly connected between the operating member 7 and the transmission seat 6, with high transmission accuracy and less slippage. The transmission ratio between the operating member 7 and the transmission seat 6 can be adjusted by adjusting the tooth number ratio of the first gear 602 and the second gear 702.

[0089] As an alternative embodiment, the transmission seat 6 and the operating member can also be drivingly connected by a belt or a chain.

[0090] In one embodiment, the operating member 7 comprises a hinged shaft 701 and a knob 703. The hinged shaft 701 is hinged to the housing 1. A second gear 702 is formed on the outer periphery of the hinged shaft 701. The knob 703 is connected to the hinged shaft 701. The housing 1 is provided with a clearance 101 on the side away from the dial 5. The knob 703 is arranged in the clearance 101. In this way, the knob 703 can be arranged on the side of the housing 1 facing the user, so that the operator can pull out the knob 703 without carrying the mechanical key 11, and rotate the transmission seat 6 through the knob 703, which is simple in structure and convenient to operate. When the knob 703 is in the clearance 101, the knob 703 is in the same plane as the housing 1, which helps to improve the aesthetics of the emergency unlocking structure.

[0091] In one embodiment, as shown in Figure 7 The housing 1 is provided with a knob limiting groove 102. The knob limiting groove 102 is connected to the clearance 101. When the knob 703 is in the knob limiting groove 102, the third mounting hole 601 is in communication with the second mounting hole 401. In this way, the operator can put the knob 703 back into the knob limiting groove 102 after unlocking with the emergency unlocking structure, so that the transmission seat 6 is reset, which facilitates the normal use of the emergency unlocking structure next time.

[0092] Next, the use method of the emergency unlocking structure of the embodiment will be described:

[0093] When the lock has an electronic failure and the user does not carry the mechanical key 11, the operator can use the mobile phone APP or other mobile terminal to communicate with the controller, control the controller through the backup circuit, drive the linear drive mechanism 9 to drive the push plate 902 to extend, push the second linkage pin 802 to move towards the first linkage pin 801, and partially enter the second mounting hole 401, while the first linkage pin 801 is forced to compress the first elastic member and exit the second mounting hole 401. At this time, the second linkage pin 802 can link the rotating seat 4 and the transmission seat 6, and the linkage between the lock cylinder 2 and the rotating seat 4 is released.

[0094] Then, the operator can pull out the knob 703 and drive the knob 703 to rotate, so as to drive the rotating seat 4 and the dial 5 to rotate through the transmission seat 6, and complete the unlocking.

[0095] When the user carries the mechanical key 11, the operator does not need to use the mobile phone APP to control the controller, and the linkage assembly is in the first state under the push of the first elastic member 803, that is, the lock cylinder 2 and the rotating seat 4 are linked with each other, and the rotating seat 4 and the transmission seat 6 are independent of each other. The operator can insert the mechanical key 11 into the key hole of the lock cylinder 2, rotate the key, so that the lock cylinder 2 rotates relative to the lock shell 3, and drives the rotating seat 4 and the dial 5 to rotate, and completes the unlocking.

[0096] According to the embodiment of the present application, in a further aspect, there is also provided a smart lock comprising the back plate 10 and the emergency unlocking structure provided by the first aspect of the present application, wherein the emergency unlocking structure is fixed on the back plate 10.

[0097] The smart lock of the present embodiment is provided with the emergency unlocking structure on the back plate 10. When the smart lock has an electronic failure and the user does not carry the mechanical key 11, the controller is controlled through the backup circuit (for example, the controller is connected through the mobile phone APP or through the Bluetooth connection and the like), so that the driving mechanism 9 switches the linkage assembly to the second state. In the second state, the first linkage pin 801 avoids the second mounting hole 401 to release the linkage between the lock barrel 2 and the rotating seat 4, so that the rotating seat 4 can rotate relative to the lock cylinder. At the same time, the second linkage pin 802 partially enters the second mounting hole 401 to make the transmission seat 6 move synchronously with the rotating seat 4. The operator can drive the operation member to rotate the rotating seat 4 and the paddle 5 through the transmission seat 6, and complete the unlocking.

[0098] The smart lock structure of the present application is simple and convenient to use, and can bring a better experience to the user.

[0099] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
