Description

Technical Field

[0001] This application relates to the field of lock technology, and in particular to a passive cabinet lock. Background Technology

[0002] Smart cabinet locks typically require a motor-driven locking mechanism to unlock and lock after authorization via an electronic key or smart terminal. This motor needs power, and depending on whether the smart cabinet lock has an internal power supply, it can be divided into active and passive types. Passive cabinet locks usually require external power for both unlocking and locking. This means that existing passive cabinet locks with external power unlocking either lock directly when power is off or require external power to lock, making it impossible to maintain an unlocked state without power and mechanically reset and lock when needed. This severely impacts the user experience. Summary of the Invention

[0003] This application provides a passive cabinet lock, which aims to solve the technical problem that existing passive cabinet locks, after being unlocked by external power supply, cannot maintain the unlocked state when there is no power and cannot mechanically reset and lock when needed, thus affecting the user experience.

[0004] Therefore, this application provides a passive cabinet lock for use in a cabinet, including a push-button module, a lock head module, and a handle assembly, wherein...

[0005] The push rod module includes an elastic push rod and a push rod control component. The elastic push rod can switch back and forth between an extended state and a retracted state under the action of elastic force and the control of the push rod control component.

[0006] The lock cylinder module includes a lock cylinder module, which has a locked state and an unlocked state. The lock cylinder module includes a passive unlocking power component and an elastic holding component. When an external power source is connected, the passive unlocking power component can switch the lock cylinder module from the locked state to the unlocked state under the control of an unlocking command. The elastic holding component can maintain the unlocked state of the lock cylinder module without external force, and can switch the lock cylinder module back from the unlocked state to the locked state through elastic force under the action of the elastic push rod in the extended state.

[0007] The handle assembly has a closed state and an open state, and is used to switch from the closed state to the open state after the lock cylinder module switches to the unlocked state, so as to open or close the cabinet.

[0008] Optionally, in some embodiments of the application, the sting rod module further includes a sting rod mounting housing having a sting rod through hole;

[0009] The elastic stab rod includes a stab rod body and a stab rod spring. The stab rod body includes a stab rod end and a base end. The base end is elastically fitted into the stab rod mounting shell through the stab rod spring. The stab rod end extends out of the stab rod mounting shell through the stab rod through hole and has the extended state and the retracted state.

[0010] The stab rod control component includes a control component body and a control component spring. The control component body is elastically assembled inside the stab rod mounting shell by the control component spring and has a pressing part that protrudes from the surface of the stab rod mounting shell. When the pressing part is pressed by an external force, the control component body squeezes the base end, causing the stab rod end to switch from the extended state to the retracted state.

[0011] Optionally, in some embodiments of the application, a first downward guide slope is provided on the base end, and a second downward guide slope is provided on the control component body to cooperate with the first downward guide slope in a downward guiding manner, so that the second downward guide slope cooperates with the first downward guide slope in a downward guiding manner, so that while the base end squeezes the push rod spring, the push rod end switches from the extended state to the retracted state.

[0012] Optionally, in some embodiments of the application, the elastic holding component includes a first torsion spring and an elastic retaining bead. The first torsion spring can undergo elastic deformation when the passive unlocking power component switches the lock cylinder module from the locked state to the unlocked state, so that the lock cylinder module has a tendency to switch back from the unlocked state to the locked state. The elastic retaining bead can lock the lock cylinder module under the action of elastic force to maintain the unlocked state of the lock cylinder module.

[0013] Optionally, in some embodiments of the application, the lock cylinder module further includes a lock cylinder housing for housing the passive unlocking power component and the elastic holding component, and a locking member for locking and unlocking the lock cylinder module;

[0014] The passive unlocking power assembly includes a motor cam, a passive unlocking motor, and an external power connector. The passive unlocking motor is electrically connected to the external power connector, and the motor shaft of the passive unlocking motor is elastically fitted with the motor cam via a first torsion spring. The motor cam is drive-connected to the locking member, so that when an external power source is connected to the external power connector, the passive unlocking motor drives the motor cam to rotate under the control of an unlocking command. This causes the first torsion spring to undergo elastic deformation, and simultaneously, the motor cam drives the locking member to unlock the lock cylinder module, thereby switching the lock cylinder module from the locked state to the unlocked state.

[0015] Optionally, in some embodiments of the application, a retaining ball mounting groove is further provided on the outer periphery of the motor cam, and the elastic retaining ball includes a retaining ball body and a retaining ball spring, wherein the retaining ball body is elastically assembled in the retaining ball mounting groove by the retaining ball spring;

[0016] The inner circumference of the lock cylinder housing is also provided with a retaining ball locking hole, so that when the motor cam rotates to a preset angle, the retaining ball body is locked into the retaining ball locking hole under the elastic force of the retaining ball spring, so that the lock cylinder module maintains the unlocked state.

[0017] Optionally, in some embodiments of the application, the handle assembly includes a resilient locking handle having the closed state and the open state;

[0018] When the elastic locking handle is in the closed state, it acts on the push rod control component, causing the elastic push rod to switch from the extended state to the retracted state.

[0019] When the elastic locking handle is in the open state, the elastic locking handle can open or close the cabinet, and the elastic push rod switches from the retracted state to the extended state under the action of elastic force.

[0020] Optionally, in some embodiments of the application, the lock cylinder module further includes a lock cylinder housing and a lock cylinder base, the lock cylinder module is installed in the lock cylinder housing, and one end of the lock cylinder housing and one end of the lock cylinder base are elastically rotatably connected by the cooperation of a first limiting pin and a second torsion spring, so that the lock cylinder module also has an inclined state and a horizontal state;

[0021] When the lock cylinder module is in the unlocked state, the lock cylinder module can switch from the horizontal state to the tilted state under the action of external force, so that the elastic locking handle switches from the closed state to the open state, and so that the elastic push rod in the extended state is aligned with the tilted elastic holding component. When the lock cylinder module switches from the tilted state back to the horizontal state under the elastic action of the second torsion spring, the elastic push rod in the extended state acts on the elastic holding component.

[0022] Optionally, in some embodiments of the application, a lock body mounting shell is further included, wherein the first end of the lock body mounting shell is respectively provided with the push rod module and the lock head module;

[0023] The elastic locking handle includes a handle body. The first end of the handle body is elastically rotatably connected to the second end of the lock body mounting shell through the cooperation of a second limiting pin and a third torsion spring. The second end of the handle body is pressed and fastened to the lock head module through the cooperation of an elastic buckle and a fixed buckle.

[0024] Optionally, in some embodiments of the application, the fixing buckle is fixed to the outer periphery of the lock housing, and the fixing buckle is provided with a third downward guide slope;

[0025] The elastic buckle includes a buckle body and a buckle spring. The buckle body is elastically mounted to the second end of the handle body by the buckle spring, so that the buckle body can extend and retract along the length of the handle body. The buckle body is also recessed with a buckle groove that cooperates with the fixed buckle and is provided with a fourth downward guide slope that cooperates with the third downward guide slope. Through the downward guide cooperation of the fourth downward guide slope and the third downward guide slope, the fixed buckle and the buckle groove are pressed and fastened together.

[0026] The technical solution provided in this application, through the aforementioned structural configuration, allows the passive unlocking power component of the lock cylinder module to switch from a locked to an unlocked state under the control of an unlocking command when an external power source is connected. Simultaneously, the elastic holding component of the lock cylinder module maintains the unlocked state of the current lock cylinder module without external force. When the passive lock needs to lock, no external power source is required. Simply operating the lever control component switches the elastic lever from a retracted to an extended state, allowing the elastic holding component to switch the lock cylinder module back from an unlocked to a locked state through the elastic force of the extended lever, thus achieving mechanical reset locking. Therefore, this technical solution solves the technical problem of existing passive lock cylinders that, after unlocking with external power, cannot maintain an unlocked state when power is off and cannot perform mechanical reset locking when needed, thus affecting the user experience.

Detailed Implementation

[0040] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0041] In one embodiment, such as Figures 1 to 11 As shown, this application embodiment provides a passive cabinet lock 1, which includes a push rod module 100, a lock head module 200, and a handle assembly. The push rod module 100 includes an elastic push rod 110 and a push rod control component 120. The elastic push rod 110 can switch back and forth between an extended state and a retracted state under the action of elastic force and the control of the push rod control component 120. The lock module 200 includes a lock cylinder module 210, which has a locked state and an unlocked state. The lock cylinder module 210 includes a passive unlocking power component 211 and an elastic holding component 212. The passive unlocking power component 211, when an external power source is connected, can switch the lock cylinder module 210 from the locked state to the unlocked state under the control of an unlocking command. The elastic holding component 212 can maintain the unlocked state of the lock cylinder module 210 without external force, and can, under the action of the extended elastic push rod 110, switch the lock cylinder module 210 back from the unlocked state to the locked state through elastic force. The handle assembly has a closed state and an open state, mainly used to switch from the closed state to the open state after the lock cylinder module 210 is switched to the unlocked state, for opening or closing the cabinet.

[0042] It is understood that the passive cabinet lock 1 in this embodiment mainly refers to a lock body that does not have its own internal power supply. An external power source is required to power the passive unlocking power component 211 for it to perform the unlocking operation. It is generally used in cabinets to open or close them. The aforementioned push-button control component 120 is a mechanical structure that controls the push-button state switching. For example, the elastic push-button 110 can be switched between extended and retracted states by pressing or twisting. When the passive unlocking power component 211 is connected to an external power source, it can simultaneously perform data interaction to verify the electronic key. After successful verification, an unlocking command is sent to the passive unlocking power component 211. The aforementioned elastic holding component 212 can maintain the unlocked state of the lock cylinder module 210 without external force. This mainly refers to the elastic rod 110 being in the retracted state, or the elastic rod 110 being in the extended state and not acting on the elastic holding component 212. The elastic holding component 212 can keep the lock cylinder module 210 in the unlocked state through locking or other means, and will not switch from the unlocked state to the locked state due to power failure of the passive unlocking power component 211. That is, if mechanical locking is not performed, the passive cabinet lock 1 after external power supply unlocking will remain in the unlocked state even after the external power supply is disconnected, until mechanical locking is performed. The aforementioned handle assembly having closed and open states specifically means that when the handle assembly is in the closed state and the lock cylinder module 210 is in the locked state, no operation can be performed on the handle assembly, that is, the handle assembly cannot be operated to open or close the cabinet door, nor can the closed state of the handle assembly be released (i.e., switched to the open state). When the lock cylinder module 210 is switched to the unlocked state, the handle assembly can be switched from the closed state to the open state (that is, the closed state of the handle assembly can be released). At this time, the handle assembly can be operated to open or close the cabinet.

[0043] In this way, the passive cabinet lock 1 of this application embodiment, through the above-described structural configuration, when it needs to perform an unlocking operation, the passive unlocking power component 211 of its lock cylinder module 210 can switch the lock cylinder module 210 from the locked state to the unlocked state under the control of the unlocking command when an external power source is connected. At the same time, the elastic holding component 212 of its lock cylinder module 210 can maintain the current unlocked state of the lock cylinder module 210 without the action of external force. When it needs to perform a locking operation, there is no need to connect an external power source. Simply operate the push rod control component 120 to switch the elastic push rod 110 from the retracted state to the extended state. Then, under the action of the extended elastic push rod 110, the elastic holding component 212 can switch the lock cylinder module 210 from the unlocked state back to the locked state through the elastic force, thereby realizing mechanical reset locking.

[0044] In some examples, such as Figures 2 to 6, Figure 10 and Figure 11 As shown, the insertion rod module 100 also includes an insertion rod mounting shell 130 with an insertion rod through hole 131. The elastic insertion rod 110 includes an insertion rod body 111 and an insertion rod spring 112. The insertion rod body 111 includes an insertion rod end 1111 and a base end 1112. The base end 1112 is elastically fitted into the insertion rod mounting shell 130 by the insertion rod spring 112. The insertion rod end 1111 extends out of the insertion rod mounting shell 130 through the insertion rod through hole 131 and has an extended state and a retracted state. The insertion rod control component 120 includes a control component body 121 and a control component spring 122. The control component body 121 is elastically fitted into the insertion rod mounting shell 130 by the control component spring 122 and has a pressing portion protruding from the surface of the insertion rod mounting shell 130. When the pressing portion is pressed by an external force, the control component body 121 presses the base end 1112, causing the insertion rod end 1111 to switch from the extended state to the retracted state. Thus, through the above structural arrangement, the control body 121 of the thrust rod control component 120 can control the thrust rod body 111 of the elastic thrust rod 110 to switch from the extended state to the retracted state under the action of the pressing external force. When the pressing external force disappears, the control body 121 of the thrust rod control component 120 can return to its original shape under the elastic restoring force of the control spring 122. At the same time, the thrust rod body 111 of the elastic thrust rod 110 can switch from the retracted state to the extended state under the elastic restoring force of the thrust rod spring 112. Furthermore, a first downward pressing guide slope 11 is provided on the base end 1112, and a second downward pressing guide slope 121 is provided to cooperate with the first downward pressing guide slope 11. Through the downward pressing guide cooperation between the second downward pressing guide slope 11 and the first downward pressing guide slope 11, the thrust rod end 1111 switches from the extended state to the retracted state while the base end 1112 presses the thrust rod spring 112. Thus, the above-mentioned structural configuration allows the thrust rod control component 120 to better control the switching of the elastic thrust rod 110 between the retracted and extended states.

[0045] In some examples, such as Figures 2 to 9 As shown, the elastic holding component 212 includes a first torsion spring 2121 and an elastic retaining bead 2122. The first torsion spring 2121 can undergo elastic deformation when the passive unlocking power component 211 switches the lock cylinder module 210 from the locked state to the unlocked state, so that the lock cylinder module 210 has a tendency to switch back from the unlocked state to the locked state. The elastic retaining bead 2122 can lock the lock cylinder module 210 under the action of elastic force to maintain the unlocked state of the lock cylinder module 210. In this way, through the above structural configuration, the elastic holding component 212 can better maintain the unlocked state of the lock cylinder module 210 without the action of external force, and can better switch the lock cylinder module 210 from the unlocked state to the locked state under the action of the elastic push rod 110 in the extended state through the action of elastic force.

[0046] In some examples, such as Figures 2 to 9 As shown, the lock cylinder module 210 also includes a lock cylinder housing 213 for housing the passive unlocking power assembly 211 and the elastic holding assembly 212, and a locking member 214 for locking and unlocking the lock cylinder module 210. The passive unlocking power assembly 211 includes a motor cam 2111, a passive unlocking motor 2112, and an external power connector 2113. The passive unlocking motor 2112 is electrically connected to the external power connector 2113, and the motor shaft of the passive unlocking motor 2112 is elastically fitted with the motor cam 2111 via a first torsion spring 2121. The motor cam 2111 is connected to the locking member 214 for transmission. When the external power connector 2113 is connected to an external power source, the passive unlocking motor 2112 drives the motor cam 2111 to rotate under the control of the unlocking command. This causes the first torsion spring 2121 to undergo elastic deformation, and at the same time, the motor cam 2111 drives the locking member 214 to unlock the lock cylinder module 210, thereby switching the lock cylinder module 210 from the locked state to the unlocked state. Thus, through the above structural configuration, the passive unlocking power component 211 can better achieve its unlocking operation on the lock cylinder module 210 through the power supply of the external power connector 2113, that is, the lock cylinder module 210 switches from the locked state to the unlocked state.

[0047] It is understandable that the external power connector 2113 mentioned above can be a TYPE-C connector, a Micro USB connector, or a communication contact, etc. It can make full use of the characteristics of the mobile phone that is carried with it having a TYPE-C interface or a Micro USB interface, so that the mobile phone can be used as an external power source to supply power, and at the same time, the data interaction function between the two can be used, so that the mobile phone can also be used as an electronic key. Thus, compared with other physical key unlocking, the mobile phone charging port direct plug-in unlocking method of this passive cabinet lock 1 has the following advantages: (1) no key cost, better economic efficiency; (2) no need to carry an extra key, convenient and easy to use.

[0048] In some examples, such as Figures 2 to 9As shown, a retaining ball mounting groove is also provided on the outer periphery of the motor cam 2111. The elastic retaining ball 2122 includes a retaining ball body and a retaining ball spring. The retaining ball body is elastically assembled into the retaining ball mounting groove (not shown in the figure) by the retaining ball spring. In this way, the assembly of the elastic retaining ball 2122 on the motor cam 2111 can be better achieved through the above structural arrangement. Furthermore, a retaining ball locking hole (not shown in the figure) is also provided on the inner periphery of the lock cylinder housing 213, so that when the motor cam 2111 rotates to a preset angle, the retaining ball body is locked into the retaining ball locking hole under the elastic force of the retaining ball spring, so that the lock cylinder module 210 remains in the unlocked state. When the motor cam 2111 rotates to the preset angle, the lock cylinder module 210 has switched from the locked state to the unlocked state. At this time, through the locking and engagement of the holding ball body and the holding ball locking hole, the motor cam 2111 can neither continue to rotate in the original direction under the drive of the passive unlocking motor 2112, nor can it rotate in the opposite direction under the elastic restoring force of the first torsion spring 2121. This allows the lock cylinder module 210 to maintain the current unlocked state well.

[0049] In some examples, such as Figures 2 to 9As shown, the handle assembly includes a resilient locking handle 300, which has a closed state and an open state. When the resilient locking handle 300 is in the closed state, it acts on the push rod control component 120, causing the resilient push rod 110 to switch from an extended state to a retracted state. When the resilient locking handle 300 is in the open state, it can perform the opening or closing operation of the cabinet, and the resilient push rod 110 switches from the retracted state to the extended state under the action of elastic force. Thus, with the above structural configuration, the resilient push rod 110 can be switched between the extended and retracted states simply by changing the state of the resilient locking handle 300 (i.e., switching back and forth between the closed and open states). Furthermore, the lock cylinder module 200 also includes a lock cylinder housing 220 and a lock cylinder seat 230. The lock cylinder module 210 is installed in the lock cylinder housing 220. One end of the lock cylinder housing 220 and one end of the lock cylinder seat 230 are elastically rotatably connected by the cooperation of a first limiting pin 21 and a second torsion spring 22, so that the lock cylinder module 210 also has an inclined state and a horizontal state. When the lock cylinder module 210 is in the unlocked state, the lock cylinder module 210 can switch from the horizontal state to the inclined state under the action of external force (generally manual pressing), so that the elastic locking handle 300 switches from the closed state to the open state, and so that the elastic push rod 110, which switches from the retracted state to the extended state, is aligned with the inclined elastic holding component 212. When the lock cylinder module 210 switches from the inclined state back to the horizontal state under the elastic action of the second torsion spring 22, the elastic push rod 110 in the extended state acts on the elastic holding component 212. Thus, the above structural design allows the elastic locking handle 300, the push rod module 100, and the lock head module 200 to better cooperate with each other, thereby better realizing the mechanical reset locking of the cabinet lock.

[0050] Understandably, only when the lock cylinder module 210 is in the unlocked state can it switch from a horizontal state to an inclined state under external force (usually manual pressing), thereby allowing the elastic locking handle 300 to switch from a closed state to an open state. When the lock cylinder module 210 is in the locked state, it cannot be pressed due to being locked, meaning it cannot switch from a horizontal state to an inclined state under external force (usually manual pressing), thus preventing the elastic locking handle 300 from switching from a closed state to an open state. This ensures that the cabinet is in a state where it cannot be opened or closed.

[0051] In some examples, such as Figures 2 to 9As shown, the passive cabinet lock 1 also includes a lock body mounting shell 400, with a push rod module 100 and a lock head module 200 respectively mounted on the first end of the lock body mounting shell 400. The elastic locking handle 300 includes a handle body 310, the first end of which is elastically rotatably connected to the second end of the lock body mounting shell 400 through the cooperation of a second limiting pin 31 and a third torsion spring 32, and the second end of which is press-fitted to the lock head module 200 through the cooperation of an elastic buckle 320 and a fixed buckle 221. Thus, with the above structural configuration, the user only needs to tilt and press the lock head module 200 to switch the lock cylinder module 210 from a horizontal state to an inclined state, thereby releasing the press-fitting connection, switching the elastic locking handle 300 from a closed state to an open state, and aligning the elastic push rod 110, which has switched from a retracted state to an extended state, with the elastic support component 212. Furthermore, the fixed buckle 221 is fixed to the outer periphery of the lock cylinder housing 220, and the fixed buckle 221 is provided with a third downward guide slope 2211. The elastic buckle 320 includes a buckle body 321 and a buckle spring 322. The buckle body 321 is elastically assembled to the second end of the handle body 310 by the buckle spring 322, so that the buckle body 321 can extend and retract along the length direction of the handle body 310. The buckle body 321 is also recessed with a buckle groove 3211 that cooperates with the fixed buckle 221, and is provided with a fourth downward guide slope 3212 that cooperates with the third downward guide slope 2211 to press and fasten the fixed buckle 221 and the buckle groove 3211.

[0052] In this way, after the phone is inserted and unlocked, the passive cabinet lock 1 is in a state of... Figure 3 The pre-unlocked state shown indicates that the lock cylinder module 210 is already unlocked. Simply tilting and pressing it will release the engagement with the resilient locking handle 300. Specifically, pressing the lock cylinder module 200 away from the resilient locking handle 300 will switch the resilient locking handle 300 to... Figure 4 The open state shown enables unlocking (i.e., the elastic locking handle 300 can be operated to open or close the cabinet). At this time, the elastic barrel rod extends, and the lock cylinder module 210 is tilted due to one side being pressed. When the lock head module 200 is released (i.e., the side of the lock head module 200 away from the elastic locking handle 300 is no longer pressed), the lock cylinder module 210 returns to its original position under the elastic force of the second torsion spring 22. Figure 5 In the horizontal position shown, the holding ball body of the elastic holding component 212 is pushed open by the push rod body 111 and slides out of the holding ball latch, releasing the force of the first torsion spring 2121, which drives the motor cam 2111 to lock. At this time, pressing the elastic locking handle 300 again requires elastic retraction and engagement since the lock cylinder module 210 is already in the locked state. Figure 6As shown, once fully engaged, the cabinet is locked (meaning the elastic locking handle 300 can no longer be operated to open or close the cabinet). At this point, the elastic locking handle 300 will press down the push rod control 120 again, and the elastic push rod 110 will retract, preparing for the next unlocking.
