Description

Technical Field

[0001] This application relates to the field of Internet of Things (IoT) device technology, and in particular to a passive lock. Background Technology

[0002] Power transmission and communication cables laid outdoors require server racks, which are equipped with locks. Traditional locks use keys for manual unlocking and locking, which is inconvenient and ill-suited to the current trend of the Internet of Things (IoT), making it difficult to manage the equipment in each rack. Therefore, server racks equipped with smart locks are becoming increasingly common. Slotted smart locks, using NFC, Bluetooth, or wireless network connections for unlocking and locking, are not only easy to operate but also facilitate the management of the opening and closing information of multiple racks. However, the internal unlocking and locking mechanisms of smart locks commonly used in server racks are complex and slow, and they are prone to accidental relocking after unlocking, affecting outdoor operations. Furthermore, some server rack locks require high power for unlocking and locking, increasing the difficulty of obtaining power outdoors. Summary of the Invention

[0003] To solve at least one of the above-mentioned technical problems, this application provides a passive lock, and the technical solution adopted is as follows.

[0004] The passive lock provided in this application includes a lock housing, a handle, a lock cylinder assembly, a locking assembly, and a stall mechanism. The handle is disposed on the surface of the lock housing. The lock cylinder assembly is disposed in the lock housing and includes a lock cylinder shaft and a lock tongue shaft. The two ends of the lock cylinder shaft are respectively connected to the handle and the lock tongue shaft. The handle drives the lock tongue shaft to rotate through the lock cylinder shaft. The outer side wall of the lock cylinder shaft has a recessed lock cylinder engagement area. The locking assembly is disposed in the lock housing and includes a first locking movable member and a second locking movable member. The second locking movable member is disposed in the first locking movable member along a first direction parallel to the axial direction of the lock cylinder shaft. The first locking movable member has a first through area through which the lock cylinder shaft passes. The second locking movable member is used to insert into the lock cylinder engagement area to engage the lock cylinder shaft. The stall mechanism includes a stall actuator, a stall clutch assembly, and a stall mechanism. The lock-rotor mechanism, driven by the lock-rotor actuator via the lock-rotor clutch assembly, moves the lock-rotor structure toward the first locking member, causing the lock-rotor structure to engage with the outer wall of the first locking member. The first locking member is switchable to a first position or a second position relative to the lock housing. When the first locking member is in the first position, the lock-rotor structure engages with the outer wall of the first locking member, and the second locking member protrudes from the inner wall of the first through-area and is inserted into the lock cylinder engagement area, or the second locking member retracts relative to the first locking member to a position where it is not engaged with the lock cylinder engagement area. When the first locking member moves to the second position along a second direction perpendicular to the first direction, the lock-rotor structure disengages from the first locking member, and the second locking member moves with the first locking member to a position where it is not engaged with the lock cylinder engagement area.

[0005] In some embodiments of this application, the locking assembly includes a first elastic member and a second elastic member. The first elastic member is disposed in the lock housing and abuts against the first locking movable member. The first elastic member applies an elastic force along a second direction to the first locking movable member, causing the first locking movable member to move from the first position to the second position. The second elastic member is disposed in the first locking movable member and abuts against the second locking movable member. The second elastic member applies an elastic force along a second direction to the second locking movable member, causing the second locking movable member to move relative to the first locking movable member, such that a first end of the second locking movable member protrudes from the inner wall of the first through-area and is inserted into the lock cylinder engagement area.

[0006] In some embodiments of this application, the outer wall of the second locking movable member is provided with a second abutment portion, the second abutment portion protruding from the outer wall of the second locking movable member, the first locking movable member is provided with a recessed first mounting area, the second locking movable member is disposed in the first mounting area, the first mounting area forms a through hole at the inner wall of the first through area for the second locking movable member to extend out, the two sides of the second abutment portion abut against the side wall of the first mounting area and the second elastic member respectively, so that when the first locking movable member moves from the first position to the second position, it drives the second locking movable member to a position that is not inserted with the lock cylinder engagement area, and so that the second elastic member applies an elastic force to the second locking movable member.

[0007] In some embodiments of this application, the first locking movable member is provided with a first abutting portion, the first abutting portion protruding from the inner sidewall of the first through area along a second direction, and the outer sidewall of the lock cylinder is provided with a first recessed area. When the first locking movable member is in the second position, the first abutting portion abuts against the bottom of the first recessed area. When the handle drives the lock cylinder to rotate, the lock cylinder switches to the circumferential sidewall of the outer sidewall of the lock cylinder abutting against the first abutting portion, so that the first locking movable member moves to the first position.

[0009] In some embodiments of this application, the first recessed area has a limiting sidewall that abuts against the first abutting portion. When the first locking movable member is in the first position and the third elastic member pushes the lock cylinder shaft to move in the first direction, the limiting sidewall abuts against the first abutting portion to stop the lock cylinder shaft from moving.

[0010] In some embodiments of this application, the passive lock includes a manual unlocking component disposed in the lock housing. The manual unlocking component includes a pull member and a toggle member. The pull member is connected to the second end of the second locking movable member. The end of the toggle member is provided with an eccentric structure. When the toggle member is manually rotated, the toggle member drives the pull member to move along a second direction through the eccentric structure, so that the pull member drives the second locking movable member to move along the second direction to a position where it is not inserted into the lock cylinder engagement area.

[0011] In some embodiments of this application, the stall clutch assembly includes a stall drive shaft, a stall clutch shaft, and a stall elastic element. The stall drive shaft is connected to the shaft of the stall actuator. The stall clutch shaft is sleeved on the outside of the stall drive shaft. The stall elastic element is disposed on the stall drive shaft and acts on both the stall drive shaft and the stall clutch shaft. The stall actuator drives the stall drive shaft to rotate forward by a set angle, and the set angle of forward rotation of the stall drive shaft includes a first stroke and an energy storage stroke. The outer peripheral sidewall of the stall clutch shaft is provided with at least two recessed stall avoidance areas spaced circumferentially. The stall drive shaft can push the stall clutch shaft to rotate forward through the stall elastic element, so that the stall clutch shaft rotates forward by a set angle. The angle, and the set angle for the forward rotation of the stall clutch shaft includes a clearance stroke and a second stroke; wherein, when the stall drive shaft completes the first stroke, the stall clutch shaft completes the clearance stroke, at which time the stall clearance area rotates to a set position M, and the stall structure moves to a position where it engages with one of the stall clearance areas, so that the stall clutch shaft is in a locked and non-rotating state; when the stall drive shaft continues to rotate forward and completes the energy storage stroke, the stall elastic element completes compression energy storage; the elastic force of the stall elastic element can push the stall clutch shaft to complete the second stroke, so that the stall clearance area rotates to a set position N, at which time the stall clearance area moves to a position misaligned with the stall structure and the stall structure is released from engagement with the stall clearance area.

[0012] In some embodiments of this application, a transmission limiting structure is provided between the stalled drive shaft and the stalled clutch shaft. The transmission limiting structure includes a transmission protrusion and a transmission recess. One of the transmission protrusion and the transmission recess is disposed on the outer peripheral sidewall of the stalled drive shaft, and the other is disposed on the inner peripheral sidewall of the stalled clutch shaft. In the forward circumferential direction of rotation, the width of the transmission recess is greater than the width of the transmission protrusion. In the forward circumferential direction of rotation, when the front sidewall of the transmission recess abuts against the front sidewall of the transmission protrusion, the energy storage stroke is completed; when the rear sidewall of the transmission recess abuts against the rear sidewall of the transmission protrusion, the second stroke is completed.

[0013] In some embodiments of this application, the stall mechanism includes a stall bracket, the stall driver and the stall clutch shaft are disposed on the stall bracket, the side wall of the stall bracket is provided with an inner channel, the stall structure is disposed in the inner channel, the two ends of the inner channel extend to form ports, when the stall avoidance area rotates to the set position M, one of the stall avoidance areas corresponds to the port at the first end of the inner channel, when the stall avoidance area rotates to the set position N, the outer peripheral side wall of the stall clutch shaft seals the port at the first end of the inner channel.

[0014] The embodiments of this application have at least the following beneficial effects: In the passive lock, the locking assembly locks the lock cylinder shaft, and the stall mechanism drives the stall structure to lock the locking assembly, so that the lock cylinder shaft is fixed and the passive lock is in a locked state. If the passive lock needs to be unlocked, the stall structure in the stall mechanism moves away from the first locking movable member, the first locking movable member moves to a second position, and the second locking movable member moves with the first locking movable member to release the lock cylinder shaft.

[0031] The following is in conjunction with the appendix Figure 1-1 To be continued Figure 3-7 The embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0032] In the description of this application, it should be understood that the use of terms such as "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" to indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings is solely for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Features defined with "first" and "second" are used to distinguish feature names and do not have special meanings. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] This application relates to a passive lock, which includes a lock housing 1000, a handle 2000, and a lock cylinder assembly. The handle 2000 is disposed on the surface of the lock housing 1000, and the lock cylinder assembly is disposed in the lock housing 1000 and is rotatable within the lock housing 1000. The handle 2000 is connected to the lock cylinder assembly, and the lock cylinder assembly is connected to the bolt. The handle 2000 drives the lock cylinder assembly to rotate, thereby unlocking the passive lock. Specifically, the lock cylinder assembly includes a lock cylinder shaft 3100 and a bolt shaft 3200, both of which are rotatably disposed in the lock housing 1000. The two ends of the lock cylinder shaft 3100 are respectively connected to the handle 2000 and the bolt shaft 3200. The handle 2000 drives the bolt shaft 3200 to rotate via the lock cylinder shaft 3100. It is understood that the bolt is disposed at the end of the bolt shaft 3200.

[0035] Furthermore, the passive lock includes a locking assembly 4000 and a locking mechanism 5000. Both the locking assembly 4000 and the locking mechanism 5000 are disposed within the lock housing 1000. The locking assembly 4000 locks the lock cylinder assembly, preventing it from rotating. The locking mechanism 5000 locks the locking assembly 4000, causing it to release its lock on the lock cylinder assembly, thus keeping the passive lock in a locked state. Correspondingly, when the locking mechanism 5000 releases its lock on the locking assembly 4000, and the locking assembly 4000 releases its lock on the lock cylinder assembly, the passive lock can be opened by rotating the lock cylinder assembly.

[0036] Referring to the accompanying drawings, the locking assembly 4000 includes a first locking movable member 4100 and a second locking movable member 4200. The first locking movable member 4100 is disposed in the lock housing 1000, and the second locking movable member 4200 is disposed within the first locking movable member 4100. The outer wall of the lock cylinder shaft 3100 has a recessed lock cylinder engagement area 3101. The second locking movable member 4200 is used to insert into the lock cylinder engagement area 3101 to engage the lock cylinder shaft 3100 and prevent the lock cylinder shaft 3100 from rotating. Further, along a first direction parallel to the axial direction of the lock cylinder shaft 3100, the first locking movable member 4100 is provided with a first through area 4101. The lock cylinder shaft 3100 is disposed in the first through area 4101, and the second locking movable member 4200 extends from the inner wall of the first through area 4101 and inserts into the lock cylinder engagement area 3101.

[0037] Understandably, the first locking member 4100 is movable within the lock housing 1000, and drives the second locking member 4200 to move, so that the second locking member 4200 separates from the lock cylinder engagement area 3101 and moves to a position where it is not engaged with the lock cylinder engagement area 3101, thereby releasing the second locking member 4200 from locking the lock cylinder shaft 3100. Furthermore, the stall mechanism 5000 can engage with the outer wall of the first locking member 4100 to lock the locking assembly 4000.

[0038] In the lock housing 1000, a first locking member 4100 extends along a second direction perpendicular to the first direction. A first through-section 4101 is positioned at the center of the first locking member 4100. The first locking member 4100 can be switched to either a first position or a second position relative to the lock housing 1000. Specifically, when the first locking member 4100 is in the first position, a locking mechanism 5000 engages with the outer wall of the first locking member 4100 to fix the first locking member 4100 in the first position. A second locking member 4200 protrudes from the inner wall of the first through-section 4101 and is inserted into the lock cylinder engagement area 3101. When the stall mechanism 5000 releases its lock on the first locking member 4100, and the first locking member 4100 moves to the second position along the second direction, the second locking member 4200 moves with the first locking member 4100 to a position where it is not engaged with the lock cylinder engagement area 3101, that is, the second locking member 4200 exits from the lock cylinder engagement area 3101. It can be understood that when the stall mechanism 5000 releases its lock on the first locking member 4100, the first locking member 4100 can switch between the first position and the second position.

[0039] It should be noted that the first locking member 4100 and the second locking member 4200 can move relative to each other along the second direction. Specifically, when the first locking member 4100 is in the first position and the second locking member 4200 is not engaged with the lock cylinder engagement area 3101, the first locking member moves from the second position to the first position along the second direction, while the second locking member 4200 remains stationary within the lock housing 1000. Subsequently, when the first locking member 4100 is in the first position, it can be understood that the second locking member 4200 retracts relative to the first locking member 4100 to a position where it is not engaged with the lock cylinder engagement area 3101. At this time, because the handle 2000 drives the lock cylinder assembly to the unlocked position, the end of the second locking movable member 4200 is misaligned with the position of the lock cylinder engagement area 3101, and the second locking movable member 4200 cannot be inserted into the lock cylinder engagement area 3101. When the user rotates the lock cylinder assembly in the opposite direction through the handle 2000, so that the position of the lock cylinder engagement area 3101 corresponds with the position of the second locking movable member 4200, the second locking movable member 4200 moves and protrudes from the inner side wall of the first through area 4101, so that the second locking movable member 4200 can be inserted into the lock cylinder engagement area 3101, thereby locking the lock cylinder shaft 3100 and preventing it from rotating.

[0040] When the passive lock is locked, the first locking member 4100 is in the first position, and the second locking member 4200 is inserted into the lock cylinder engagement area 3101. When the first locking member 4100 moves to the second position, the second locking member 4200 disengages from the lock cylinder engagement area 3101. At this time, the user unlocks the passive lock by rotating the lock cylinder assembly using the handle 2000. Simultaneously with the lock cylinder assembly being rotated to unlock, the first locking member 4100 moves to the first position, while the second locking member 4200 remains stationary. When the user locks the passive lock by rotating the lock cylinder assembly using the handle 2000, the lock cylinder engagement area 3101 rotates to the position corresponding to the second locking member 4200, and the second locking member 4200 is inserted into the lock cylinder engagement area 3101, thus locking the passive lock.

[0041] Referring to the accompanying drawings, the lock cylinder shaft 3100 is configured as a round shaft with a cylindrical outer peripheral sidewall. The lock cylinder engagement area 3101 is recessed into the outer peripheral sidewall of the lock cylinder shaft 3100. It can be understood that when the lock cylinder shaft 3100 rotates to a position where the lock cylinder engagement area 3101 is misaligned with the second locking movable member 4200, the outer peripheral sidewall of the lock cylinder shaft 3100 abuts against the end of the second locking movable member 4200 to prevent the second locking movable member 4200 from moving, thus preventing the second locking movable member 4200 from locking the lock cylinder shaft 3100.

[0042] In one embodiment, the locking assembly 4000 includes a first elastic element 4301, which is disposed in the lock housing 1000 and abuts against a first locking movable member 4100. Specifically, the first elastic element 4301 has compressive elastic potential energy, and when the first locking movable member 4100 is in a first position, the first elastic element 4301 compresses and stores energy.

[0043] Understandably, the first elastic member 4301 applies an elastic force along the second direction to the first locking movable member 4100, so that the first locking movable member 4100 moves from the first position to the second position.

[0044] In the upper part of the inner cavity of the lock housing 1000, one end of the first elastic member 4301 abuts against the inner wall of the lock housing 1000, and the other end abuts against the end of the first locking movable member 4100. Further, the first elastic member 4301 is configured as a spring.

[0045] In one embodiment, the first locking member 4100 is provided with a first abutment portion 4103, which protrudes from the inner wall of the first through area 4101 along a second direction. When the user unlocks the lock cylinder assembly by rotating the handle 2000, the outer wall of the lock cylinder shaft 3100 contacts the first abutment portion 4103, and by pushing the first abutment portion 4103, the first locking member 4100 moves from a second position to a first position along the second direction.

[0046] Specifically, the outer wall of the lock cylinder 3100 has a cam profile. When the lock cylinder 3100 rotates, the cam profile sidewall of the lock cylinder 3100 pushes the first abutment portion 4103. Referring to the accompanying drawings, the outer wall of the lock cylinder 3100 is provided with a first recessed area 3102, the bottom surface of which forms a cam profile with the outer peripheral sidewall of the lock cylinder 3100. When the passive lock is in an upright state, the first abutment portion 4103 is located on the upper side of the lock cylinder 3100. Further, the bottom surface of the first recessed area 3102 is configured as a flat surface or an arc surface.

[0047] Understandably, during the process of the first locking movable member 4100 moving from the first position to the second position, the first abutment portion 4103 moves closer to the first recessed area 3102. When the first locking movable member 4100 is in the second position, the first abutment portion 4103 abuts against the bottom of the first recessed area 3102. When the user rotates the lock cylinder shaft 3100 by the handle 2000, the lock cylinder shaft 3100 switches to abutting the first abutment portion 4103 with the circumferential side wall of its outer sidewall, so that the first locking movable member 4100 moves to the first position, and at this time the outer sidewall of the lock cylinder shaft 3100 remains against the first abutment portion 4103, so that the first locking movable member 4100 remains in the first position.

[0048] In one embodiment, the outer side wall of the second locking movable member 4200 is provided with a second abutment portion 4201, which protrudes from the outer side wall of the second locking movable member 4200. When the first locking movable member 4100 moves from the first position to the second position, the first locking movable member 4100 abuts against the second abutment portion 4201 to cause the second locking movable member 4200 to move with the first locking movable member 4100.

[0049] Referring to the accompanying drawings, the first locking movable member 4100 is provided with a recessed first mounting area 4102, which extends along a second direction. The second locking movable member 4200 is disposed in the first mounting area 4102, which communicates with the first through area 4101. Specifically, the first mounting area 4102 forms a through hole in the inner sidewall of the first through area 4101 for the second locking movable member 4200 to extend out. It can be understood that at the sidewall where the through hole is located in the first mounting area 4102, the second abutting part 4201 abuts against the sidewall of the first mounting area 4102, so that when the first locking movable member 4100 moves from the first position to the second position, it drives the second locking movable member 4200 to move to a position where it is not inserted into the lock cylinder engagement area 3101.

[0050] In some examples, the second locking member 4200 extends along the second direction as a rod-shaped structure, the second abutment 4201 is configured as a shoulder of the second locking member 4200, and the diameter of the second abutment 4201 is larger than the diameter of the through hole between the first mounting area 4102 and the first through area 4101.

[0051] In one embodiment, the locking assembly 4000 includes a second elastic member 4302 disposed in the first locking movable member 4100, and the second elastic member 4302 abuts against the second locking movable member 4200. Specifically, the second elastic member 4302 is disposed in the first mounting area 4102, and the second elastic member 4302 has compressive elastic potential energy. When the first locking movable member 4100 is in the first position and the second locking movable member 4202 is in the position not inserted with the lock cylinder engagement area 3101, the second elastic member 4302 compresses and stores energy.

[0052] Understandably, the second elastic member 4302 applies an elastic force along the second direction to the second locking member 4200, causing the second locking member 4200 to move relative to the first locking member 4100, so that the first end of the second locking member 4200 protrudes from the inner wall of the first through area 4101 and engages with the lock cylinder engagement area 3101. Specifically, when the user rotates the lock cylinder assembly via the handle 2000 to lock the passive lock, the lock cylinder engagement area 3101 rotates to the position corresponding to the second locking member 4200, and under the push of the second elastic member 4302, the end of the second locking member 4200 inserts into the lock cylinder engagement area 3101.

[0053] In some examples, the second elastic element 4302 is configured as a spring, the second elastic element 4302 is sleeved on the outer side wall of the second locking movable element, and the second abutting part 4201 abuts against the second elastic element 4302, so that the second elastic element 4302 applies an elastic force to the second locking movable element.

[0054] In one embodiment, the lock case 1000 includes a cover 1100 and a base plate 1200. Referring to the accompanying drawings, the cover 1100 is located on one side of the base plate 1200. The cover 1100 and the base plate 1200 are connected to form the inner cavity of the lock case 1000. The handle 2000 is disposed on the outer side of the cover 1100. The first locking movable member 4100 is disposed on the inner side of the base plate 1200. The cover 1100 and the base plate 1200 are provided with through holes corresponding to the first through area 4101. The lock cylinder shaft 3100 is rotatably disposed at the through hole of the base plate 1200.

[0055] The lock cylinder assembly includes a lock cylinder seat 3500, a bolt shaft 3200 passing through the lock cylinder seat 3500, and the bolt shaft 3200 being rotatably connected to the lock cylinder seat 3500. Referring to the accompanying drawings, the lock cylinder seat 3500 is disposed on the outer side of the base plate 1200, and both ends of the lock cylinder seat 3500 are connected to the base plate 1200 via first locking members 3501. Further, the first locking member 3501 passes through the base plate 1200, and its end protrudes from the inner side of the base plate 1200. The first locking member 3501 serves as a guide structure for the first locking movable member 4100 to move in a second direction.

[0056] Specifically, both ends of the first locking movable member 4100 are provided with a first slide groove 4104 facing the bottom plate 1200. The first slide groove 4104 extends along the second direction, and the end of the first locking member 3501 extends into the first slide groove 4104. The end of the first locking member 3501 cooperates with the first slide groove 4104 so that the first locking movable member 4100 moves smoothly along the second direction.

[0057] Furthermore, the first locking member 3501 has a positioning and limiting function for the first locking movable member 4100. The side wall of the first locking member 3501 abuts against the inner side wall of the end of the first slide groove 4104, thus stopping the movement of the first locking movable member 4100. Specifically, when the first locking movable member 4100 moves from the first position to the second position, the side wall of the first locking member 3501 abuts against the side wall of one end of the first slide groove 4104, stopping the movement of the first locking movable member 4100, which is then positioned in the second position. Correspondingly, when the first locking movable member 4100 moves from the second position to the first position, the side wall of the first locking member 3501 abuts against the side wall of the other end of the first slide groove 4104, stopping the movement of the first locking movable member 4100, which is then positioned in the first position.

[0058] In one embodiment, the lock cylinder 3100 is hollow and sleeved on the outside of the latch cylinder 3200. The lock cylinder 3100 can move relative to the latch cylinder 3200 in a first direction to lift the handle 2000 on the surface of the lock housing 1000. It should be noted that when the passive lock is locked, the handle 2000 is in an inoperable position on the surface of the lock housing 1000. Therefore, in this application, the lock cylinder 3100 is designed to lift the handle 2000 so that the handle 2000 is exposed on the surface of the lock housing 1000 for user operation.

[0059] The lock cylinder assembly includes a third elastic element 3300, which is disposed within the lock cylinder shaft 3100 and abuts against the lock cylinder shaft 3100. Specifically, the third elastic element 3300 possesses compressive elastic potential energy. When the passive lock is engaged, the lock cylinder shaft 3100 presses against the third elastic element 3300, causing the third elastic element 3300 to compress and store energy. It can be understood that the third elastic element 3300 applies an elastic force along a first direction to the lock cylinder shaft 3100, causing the lock cylinder shaft 3100 to move along the first direction.

[0060] When the first locking member 4100 moves from the first position to the second position and drives the second locking member 4200 to a position where it is not engaged with the lock cylinder engagement area 3101, the third elastic member 3300 pushes the lock cylinder shaft 3100 to move, thereby lifting the handle 2000. Further, after the user completes the locking of the passive lock by rotating the lock cylinder assembly using the handle 2000, the user presses the surface of the handle 2000 to cause the handle 2000 to push the lock cylinder shaft 3100 to move, causing the lock cylinder engagement area 3101 to move along the first direction to the position corresponding to the second locking member 4200, so that the second locking member 4200 engages the lock cylinder shaft 3100.

[0061] It is understandable that the second locking member 4200 is inserted into the lock cylinder engagement area 3101 to prevent the lock cylinder shaft 3100 from moving: on the one hand, to prevent the lock cylinder shaft 3100 from rotating; on the other hand, to prevent the lock cylinder shaft 3100 from moving in the first direction.

[0062] In some embodiments, the first recessed area 3102 has a limiting sidewall that abuts against the first abutting portion 4103. Referring to the accompanying drawings, on the outer sidewall of the lock cylinder 3100, the first recessed area 3102 extends along a first direction and forms a limiting sidewall parallel to a second direction. The side of the first abutting portion 4103 is used to abut against the limiting sidewall. Specifically, when the first locking member 4100 is in the first position and the third elastic member 3300 pushes the lock cylinder 3100 to move along the first direction, the limiting sidewall abuts against the first abutting portion 4103 to stop the lock cylinder 3100 from moving, thereby limiting the movement distance of the lock cylinder 3100 along the first direction, and thus limiting the extent to which the handle 2000 is pushed against the surface of the lock housing 1000.

[0063] In one implementation, the lock cylinder 3100 can drive the bolt 3200 to rotate in a snap-fit ​​manner. On the one hand, the lock cylinder 3100 can move relative to the bolt 3200 in a first direction; on the other hand, the lock cylinder 3100 can drive the bolt 3200 to rotate, thereby unlocking or locking the passive lock.

[0064] Referring to the accompanying drawings, the lock cylinder assembly includes a snap-fit ​​sleeve 3400. A lock cylinder shaft 3100 is fitted onto the outer wall of a latch shaft 3200 via the snap-fit ​​sleeve 3400, and the lock cylinder shaft 3100 drives the latch shaft 3200 to rotate via the snap-fit ​​sleeve 3400. Specifically, the lock cylinder shaft 3100 is fitted onto the outer wall of the snap-fit ​​sleeve 3400, and the lock cylinder shaft 3100 is movable relative to the snap-fit ​​sleeve 3400 in a first direction to lift the handle 2000 onto the surface of the lock housing 1000. The inner wall of the lock cylinder shaft 3100 engages with the outer wall of the snap-fit ​​sleeve 3400, and the snap-fit ​​sleeve 3400 is fitted onto the outer wall of the latch shaft 3200, with the inner wall of the snap-fit ​​sleeve 3400 engaging with the outer wall of the latch shaft 3200.

[0065] It should be noted that the two ends of the third elastic element 3300 abut against the snap sleeve 3400 and the lock cylinder shaft 3100, respectively.

[0066] Of course, the connection between the lock cylinder shaft 3100 and the lock tongue shaft 3200 can be alternatively designed as follows: the lock cylinder shaft 3100 is sleeved on the outer side wall of the lock tongue shaft 3200, and the inner side wall of the lock cylinder shaft 3100 is engaged with the outer side wall of the lock tongue shaft 3200, with the two ends of the third elastic member 3300 abutting against the lock cylinder shaft 3100 and the lock tongue shaft 3200 respectively.

[0067] In one embodiment, the surface of the lock case 1000 is provided with a second recessed area for placing the handle 2000. Referring to the accompanying drawings, the second recessed area is set on the outer side of the cover 1100, and the second recessed area is adapted to the shape of the handle 2000.

[0068] Understandably, when the lock cylinder shaft 3100 lifts the handle 2000 from the surface of the lock housing 1000, the handle 2000 separates from the second recessed area, allowing the user to rotate the handle 2000. When the user presses the handle 2000, the side of the handle 2000 facing the lock housing 1000 enters the second recessed area, at least partially containing the handle 2000 to prevent accidental rotation. Furthermore, the inner wall of the second recessed area abuts against the outer surface of the handle 2000, also preventing rotation of the handle 2000.

[0069] This application relates to a stall mechanism 5000. Referring to the accompanying drawings, the stall mechanism 5000 includes a stall driver 5100, a stall clutch assembly, and a stall structure 5700. The stall driver 5100 drives the stall structure 5700 to move towards a first locking member 4100 via the stall clutch assembly, so that the stall structure 5700 engages with the outer side wall of the first locking member 4100. Specifically, the outer side wall of the first locking member 4100 is provided with a third recessed area. The stall structure 5700 can move to the third recessed area and engage with the side wall of the third recessed area, thereby achieving the engagement of the stall structure 5700 with the first locking member 4100.

[0070] Specifically, the stall clutch assembly includes a stall drive shaft 5200, a stall actuator 5100 including a motor, and the output end of the stall actuator 5100 having a rotating shaft. The stall drive shaft 5200 is connected to the rotating shaft of the stall actuator 5100, and the stall actuator 5100 drives the stall drive shaft 5200 to rotate in the forward direction. The stall drive shaft 5200 and the rotating shaft of the stall actuator 5100 are integrally formed or snap-fitted together.

[0071] It should be noted that, under the drive of the stall drive 5100, the stall drive shaft 5200 rotates in either a clockwise or counterclockwise direction. Forward rotation does not refer to a specific direction, but rather to the direction in which the stall drive shaft 5200 rotates. Once the direction of rotation of the stall drive shaft 5200 is determined, it is considered the forward rotation direction.

[0072] Referring to the accompanying drawings, the stall clutch assembly includes a stall clutch shaft 5300, which is cylindrical in shape and sleeved on the outside of the stall drive shaft 5200. Further, the outer peripheral sidewall of the stall clutch shaft 5300 is provided with at least two recessed stall avoidance areas 5301 spaced circumferentially. The stall drive shaft 5200 can drive the stall clutch shaft 5300 to rotate forward, thereby changing the position of the stall avoidance areas 5301. It is understood that the diameter of the circumference of the sidewall formed by the stall avoidance areas 5301 along the circumference surrounding the central axis of the stall clutch shaft 5300 is smaller than the diameter of the circumference of the outer sidewall of the stall clutch shaft 5300.

[0073] The stall clutch assembly includes a stall elastic element 5400, which is disposed on the stall drive shaft 5200 and acts on both the stall drive shaft 5200 and the stall clutch shaft 5300. The stall drive shaft 5200 can drive the stall clutch shaft 5300 to rotate forward through the stall elastic element 5400, and the elastic force of the stall elastic element 5400 itself can also drive the stall clutch shaft 5300 to rotate forward. It can be understood that the stall clutch shaft 5300 achieves forward rotation in two ways: one is that when the stall actuator 5100 drives the stall drive shaft 5200 to rotate forward, the stall drive shaft 5200 drives the stall clutch shaft 5300 to rotate forward through the stall elastic element 5400; the other is that the stall drive shaft 5200 does not rotate, but the elastic force of the stall elastic element 5400 drives the stall clutch shaft 5300 to rotate forward.

[0074] The stall drive shaft 5200 can rotate forward by a set angle, and this set angle includes a first stroke and an energy storage stroke. Specifically, the stall drive shaft 5200 first completes the first stroke and then completes the energy storage stroke. The stall clutch shaft 5300 can rotate forward by a set angle, and this set angle includes a clearance stroke and a second stroke. Specifically, the stall clutch shaft 5300 first completes the clearance stroke and then completes the second stroke.

[0075] It should be noted that, driven by the stall actuator 5100, the stall drive shaft 5200 rotates forward to complete the first stroke, and the stall drive shaft 5200 pushes the stall clutch shaft 5300 to rotate forward through the stall elastic element 5400, so that the stall clutch shaft 5300 performs a clearance stroke. When the stall clearance area 5301 rotates to the set position M, the stall clutch shaft 5300 completes the clearance stroke, at which point the stall clutch shaft 5300 is in a locked and non-rotating state. Driven by the stall actuator 5100, the stall drive shaft 5200 continues to rotate forward and performs an energy storage stroke. The stall elastic element 5400 is compressed. When the stall drive shaft 5200 completes energy storage, the stall elastic element 5400 completes compression energy storage. Subsequently, the elastic force of the stall elastic element 5400 can push the stall clutch shaft 5300 to disengage the stall clutch shaft 5300. Under the push of the elastic force of the stall elastic element 5400, the stall clutch shaft 5300 rotates forward and completes the second stroke, so that the stall avoidance area 5301 rotates to the set position N.

[0076] Furthermore, the stall mechanism 5000 includes a stall structure 5700, which engages the first locking member 4100 to fix it in place. The stall structure 5700 is reciprocating and can move back and forth between the stall clutch shaft 5300 and the first locking member 4100 to engage or disengage the first locking member 4100. Specifically, the stall structure 5700 can move to a position where it engages with the stall clearance area 5301, at which point the stall structure 5700 separates from and releases the engagement with the first locking member 4100; alternatively, the stall structure 5700 can move in the opposite direction to a position where it is released from engagement with the stall clearance area 5301, at which point the stall structure 5700 approaches and engages with the first locking member 4100, thus fixing the first locking member 4100 in place. It can be understood that the movement of the stall structure 5700, in conjunction with the rotation of the stall clutch shaft 5300, achieves engagement or disengagement between the stall structure 5700 and the first locking member 4100, thereby enabling the passive lock to lock or unlock.

[0077] Between the stall clutch shaft 5300 and the first locking movable member 4100, the stall structure 5700 can move to the third position or in the opposite direction to the fourth position. Specifically, from the fourth position to the third position, the stall structure 5700 moves towards the stall clutch shaft 5300. When the stall structure 5700 moves to the third position, the stall structure 5700 is disengaged from the first locking movable member 4100, and the stall structure 5700 partially enters the stall clearance area 5301. The stall structure 5700 engages with the stall clearance area 5301 to achieve engagement between the stall structure 5700 and the stall clutch shaft 5300. Under the abutment of the outer wall of the first locking movable member 4100, the stall structure 5700 maintains engagement with the stall clearance area 5301. From the third position to the fourth position, the stall structure 5700 moves toward the first locking movable member 4100. When the outer wall of the first locking movable member 4100 releases its abutment against the stall structure 5700, the stall structure 5700 moves to the fourth position. At this time, the stall structure 5700 moves away from the stall clearance area 5301, and the stall structure 5700 is released from the stall clearance area 5301, so as to realize the release of the stall structure 5700 from the stall clutch shaft 5300. The stall structure 5700 is engaged with the first locking movable member 4100, and under the abutment of the outer wall of the stall clutch shaft 5300, the stall structure 5700 maintains the engagement with the first locking movable member 4100.

[0078] Understandably, when the stall clearance area 5301 rotates to the set position M, the stall structure 5700 moves to the third position and engages with one of the stall clearance areas 5301, so that the stall clutch shaft 5300 is in a locked and non-rotating state. At this time, the stall structure 5700 separates from the first locking movable member 4100 and releases the engagement, thereby releasing the first locking movable member 4100 from its fixation, allowing the first locking movable member 4100 to move, and the passive lock to unlock. When the stall avoidance zone 5301 rotates to the set position N, the stall avoidance zone 5301 moves to a position that is misaligned with the stall structure 5700. The stall structure 5700 leaves the stall avoidance zone 5301 and moves to the fourth position. The stall structure 5700 and the stall avoidance zone 5301 are released from the engagement. At this time, the stall structure 5700 engages with the first locking movable member 4100, thereby fixing the first locking movable member 4100 and preventing it from moving, thus locking the passive lock.

[0079] In one embodiment, the stall mechanism 5000 includes a stall bracket 5600, a stall driver 5100 and a stall clutch shaft 5300 disposed in the stall bracket 5600, the stall bracket 5600 is hollow to form a third mounting area, and the stall driver 5100 and the stall clutch shaft 5300 are disposed in the third mounting area.

[0080] Furthermore, the side wall of the stall bracket 5600 is provided with an inner channel that penetrates the side wall of the stall bracket 5600. The two ends of the inner channel extend to form ports. The first end of the inner channel extends to the third installation area to form a port connecting the third installation area, and the second end of the inner channel extends to the outer side of the stall bracket 5600.

[0081] Referring to the attached diagram, the stall structure 5700 is disposed in the inner channel, and the stall structure 5700 can reciprocate within the inner channel to reach the port of the inner channel. It can be understood that when the stall structure 5700 moves to the first port of the inner channel, it is in the third position; when it moves to the second port of the inner channel, it is in the fourth position.

[0082] It is understandable that when the stall avoidance area 5301 rotates to the set position M, one of the stall avoidance areas 5301 of the stall clutch shaft 5300 corresponds to the port at the first end of the inner channel, so that the stall structure 5700 can be engaged with the stall avoidance area 5301. When the stall avoidance area 5301 rotates to the set position N, the stall avoidance area 5301 is misaligned with the port of the first end of the inner channel, so that the stall avoidance area 5301 is misaligned with the stall structure 5700, thereby the stall structure 5700 leaves the stall avoidance area 5301, realizing the release of the stall structure 5700 from the stall avoidance area 5301. During the rotation of the stall clutch shaft 5300, the concave side wall of the stall avoidance area 5301 and the side wall of the stall clutch shaft 5300 gradually abut against the stall structure 5700, so as to push the stall structure 5700 from the third position to the fourth position. After that, the outer peripheral side wall of the stall clutch shaft 5300 seals the port of the first end of the inner channel, and the outer peripheral side wall of the stall clutch shaft 5300 maintains abutment against the stall structure 5700, so that the stall structure 5700 remains in the fourth position.

[0083] In one implementation, the stall structure 5700 is configured as a spherical structure, with its outer peripheral surface formed as a spherical surface. Further, the stall structure 5700 is configured as a steel ball.

[0084] During the second stroke of the forward rotation of the stall clutch shaft 5300, when the stall avoidance area 5301 rotates from the set position M to the set position N, the spherical sidewall of the stall structure 5700 abuts against the sidewall of the stall avoidance area 5301, which helps the stall clutch shaft 5300 push the stall structure 5700. Specifically, the spherical sidewall of the stall structure 5700 acts as a guide surface. When the concave sidewall of the stall avoidance area 5301 transitions to the outer circumferential sidewall of the stall clutch shaft 5300, the spherical sidewall of the stall structure 5700 can transition well, better completing the pushing of the stall structure 5700, so that the stall structure 5700 moves from the third position to the fourth position.

[0085] Furthermore, the stall avoidance position is configured as a spherical concave hole, and the sidewall of the concave position of the stall avoidance position is formed as a spherical surface.

[0086] Regarding the shape of the stall structure 5700, it can at least be alternatively designed as follows: the stall structure 5700 is configured as a columnar structure with a spherical end face. Further, the stall structure 5700 can be configured as a steel column with a spherical end face.

[0087] It should be noted that when the stall drive shaft 5200 completes its first stroke, it pushes the stall clutch shaft 5300 to perform a clearance stroke. The stall clutch shaft 5300 rotates a set angle A, at which point the stall clearance area 5301 rotates to a set position M, and the stall structure 5700 engages with the stall clearance area 5301 to fix the stall clutch shaft 5300 in place. At this point, the stall clutch shaft 5300 completes its clearance stroke. That is, when the stall structure 5700 engages with the stall clearance area 5301 corresponding to the first end of the inner channel, the clearance stroke of the stall clutch shaft 5300 is completed.

[0088] Under the elastic push of the stall elastic element 5400, when the stall clutch shaft 5300 completes the second stroke, the stall clutch shaft 5300 rotates by a set angle B. At this time, the stall clearance area 5301 and the stall structure 5700 are misaligned, and the outer peripheral sidewall of the stall clutch shaft 5300 abuts against the stall structure 5700.

[0089] Furthermore, on the outer peripheral sidewall of the stall clutch shaft 5300, the included angle C formed by the center positions of two adjacent stall avoidance areas 5301 on the circumference satisfies: C=A+B. When the stall clutch shaft 5300 completes the avoidance stroke and the second stroke by rotating forward, the next stall avoidance area 5301 moves to the position of the previous stall avoidance area 5301, completing the position change of two adjacent stall avoidance areas 5301.

[0090] It is understandable that the stall avoidance zones 5301 are evenly distributed on the outer peripheral sidewall of the stall clutch shaft 5300. Each time the stall clutch shaft 5300 completes one avoidance stroke and one second stroke, the stall clutch shaft 5300 rotates by an angle C, so that each stall avoidance zone 5301 rotates sequentially to the position of the port at the first end of the corresponding inner channel.

[0091] It should be noted that the interval between two adjacent stall avoidance zones 5301 refers to the circumferential distance between the center positions of the two adjacent stall avoidance zones 5301. Furthermore, when the stall clutch shaft 5300 completes its second stroke, the middle position of the outer peripheral sidewall between two adjacent stall avoidance zones 5301 of the stall clutch shaft 5300 abuts against the stall structure 5700.

[0092] In one embodiment, a transmission limiting structure is provided between the stalled drive shaft 5200 and the stalled clutch shaft 5300, and at least one transmission limiting structure is provided. The transmission limiting structure includes a transmission protrusion 5501 and a transmission recess 5502. One of the transmission protrusion 5501 and the transmission recess 5502 is located on the outer peripheral sidewall of the stalled drive shaft 5200, and the other is located on the inner peripheral sidewall of the stalled clutch shaft 5300. During forward rotation, the stalled drive shaft 5200 and the stalled clutch shaft 5300 are positioned relative to each other through the engagement of the transmission protrusion 5501 and the transmission recess 5502.

[0093] Furthermore, along the circumferential direction of forward rotation, the width of the transmission recess 5502 is greater than the width of the transmission protrusion 5501. Specifically, along the circumferential direction of forward rotation, when the front sidewall of the transmission recess 5502 abuts against the front sidewall of the transmission protrusion 5501, the energy storage stroke is completed; when the rear sidewall of the transmission recess 5502 abuts against the rear sidewall of the transmission protrusion 5501, the second stroke is completed.

[0094] When the stalled drive shaft 5200 is in its first stroke, it pushes the stalled clutch shaft 5300 through the stalled elastic element 5400. A gap exists between the front sidewall of the transmission protrusion 5501 and the front sidewall of the transmission recess 5502. When the stalled drive shaft 5200 is in its energy storage stroke, since the stalled clutch shaft 5300 is fixed and does not rotate, the stalled drive shaft 5200 rotates forward relative to the stalled clutch shaft 5300. The front sidewall of the transmission protrusion 5501 gradually approaches the front sidewall of the transmission recess 5502 until it abuts against the front sidewall of the transmission protrusion 5501. At this point, the stalled drive shaft 5200 stops rotating, and the energy storage stroke is complete. At this time, a gap exists between the rear sidewall of the transmission protrusion 5501 and the rear sidewall of the transmission recess 5502.

[0095] When the outer wall of the stall clutch shaft 5300 releases its contact with the stall structure 5700, the elastic force of the stall elastic element 5400 pushes the stall clutch shaft 5300 to rotate forward for the second stroke. Since the stall drive shaft 5200 is fixed and does not rotate, the stall clutch shaft 5300 rotates forward relative to the stall drive shaft 5200. The rear side wall of the transmission recess 5502 gradually approaches the rear side wall of the transmission protrusion 5501 until the rear side wall of the transmission protrusion 5501 abuts against the rear side wall of the transmission recess 5502. At this point, the stall clutch shaft 5300 stops rotating, and the stall clutch shaft 5300 completes its second stroke. At this time, there is a gap between the front side wall of the transmission protrusion 5501 and the front side wall of the transmission recess 5502.

[0096] In some embodiments, at least two transmission limiting structures are provided, and each transmission limiting structure is distributed at equal intervals along the circumference.

[0097] In some examples, referring to the accompanying drawings, the transmission recess 5502 is provided on the inner sidewall of the stalled clutch shaft 5300, and the transmission protrusion 5501 is provided on the outer sidewall of the stalled drive shaft 5200. Further, at least two transmission recesses 5502 are provided at equal intervals on the inner sidewall of the stalled clutch shaft 5300, and at least two transmission protrusions 5501 are provided at equal intervals on the outer sidewall of the stalled drive shaft 5200.

[0098] In other alternative examples, the transmission recess 5502 is provided on the outer side wall of the stalled drive shaft 5200, and the transmission protrusion 5501 is provided on the inner side wall of the stalled clutch shaft 5300. Further, at least two transmission recesses 5502 are provided at equal intervals on the outer side wall of the stalled drive shaft 5200, and at least two transmission protrusions 5501 are provided at equal intervals on the outer side wall of the stalled clutch shaft 5300. As one embodiment, the stall elastic member 5400 is configured as a torsional elastic member, having two torsion arms that abut against the stalled drive shaft 5200 and the stalled clutch shaft 5300, respectively.

[0099] Referring to the attached drawings, the side wall of the stall clutch shaft 5300 is provided with a hooking area 5302. The hooking area 5302 is recessed in the side wall of the stall clutch shaft 5300 and forms a notch in the side wall of the stall clutch shaft 5300. A torsion arm of the stall elastic member 5400 is provided in the hooking area 5302. Furthermore, the side of the torsion arm abuts against the front side wall of the hooking area 5302, so that when the stall drive shaft 5200 pushes the stall clutch shaft 5300 through the stall elastic member 5400, the torsion arm of the stall elastic member 5400 can apply force to the front side wall of the hooking area 5302.

[0100] Furthermore, the stall drive shaft 5200 is provided with a hollow second mounting area, the stall elastic member 5400 is disposed in the second mounting area, and another torsion arm of the stall elastic member 5400 abuts against the inner sidewall of the second mounting area.

[0101] Of course, as an alternative, the installation method of the stall elastic element 5400 and the stall drive shaft 5200 can be designed as follows: the stall elastic element 5400 is sleeved on the stall drive shaft 5200, and one end of the stall drive shaft 5200 is provided with a column for sleeved on the stall elastic element 5400.

[0102] In one implementation, the stall actuator 5100 acquires power and signals via NFC connection. Specifically, the passive lock includes an NFC component 6000, which is electrically connected to the stall actuator 5100. The user connects an NFC unlocker to the NFC component 6000 to achieve power supply and signal transmission, thereby enabling the stall mechanism 5000 to obtain the necessary power to start. In use, the user attaches the NFC unlocker to the surface of the passive lock, the stall actuator 5100 receives power and starts, thereby driving the stall drive shaft 5200 to rotate forward.

[0103] It should be noted that, considering the inconvenience of using electricity in outdoor environments and the limited power storage of the passive lock itself, the passive lock cannot store much power. If the first locking movable part 4100 is directly driven by a motor, the movement of the first locking movable part 4100 is large, the motor requires a large power, and correspondingly the motor consumes a large amount of electricity.

[0104] However, considering the inconvenience of outdoor power supply, this application designs a locking mechanism 5000 in conjunction with a movable locking structure 5700 to engage the first locking movable member 4100. The locking actuator 5100 drives the locking transmission shaft 5200, which pushes the locking clutch shaft 5300 to rotate by a small set angle A, thereby releasing the locking structure 5700 from engaging the first locking movable member 4100. The locking actuator 5100 then drives the locking transmission shaft 5200 to rotate and compress the locking elastic member 5400, thereby using the elastic force of the locking elastic member 5400 to push the locking clutch shaft 5300 to rotate by a small set angle B, thus enabling the locking structure 5700 to engage the first locking movable member 4100. In this case, since the movement distance of the stalled rotor structure 5700 is small, the power required for the stalled rotor actuator 5100 to drive the stalled rotor drive shaft 5200 to rotate is also small. Therefore, the stalled rotor actuator 5100 consumes little power. The power supply of the stalled rotor actuator 5100 can be met by the user supplying power to the stalled rotor actuator 5100 through the NFC connection with the NFC unlocker.

[0105] On the other hand, when the motor of the stall drive 5100 stops running, the shaft of the stall drive 5100 will continue to rotate due to its own inertia. In this case, if the stall drive shaft 5200 and the stall clutch shaft 5300 are fixedly connected, if the shaft drives the stall drive shaft 5200 and the stall clutch shaft 5300 to continue rotating when the motor stops running, it will cause the position of the stall avoidance area 5301 to shift. If the stall structure 5700 jams the stall clutch shaft 5300, preventing the stall clutch shaft 5300, the stall drive shaft 5200, and the shaft of the stall drive 5100 from rotating, the motor may be damaged. Therefore, a stalling elastic element 5400 is provided between the stalled drive shaft 5200 and the stalled clutch shaft 5300 to buffer the rotation and convert the kinetic energy of this rotation into the elastic potential energy of the stalling elastic element 5400. Then, the elastic potential energy of the stalling elastic element 5400 is converted into the kinetic energy that pushes the stalled clutch shaft 5300 to rotate in the forward direction to complete the second stroke.

[0106] Furthermore, compared to conventional technologies that utilize the forward and reverse rotation of the motor or two consecutive forward rotations, this application uses an NFC unlocker to power and start the stall driver 5100 once, and utilizes the stall elastic element 5400 to compress and store energy, thereby achieving two rotations of the stall clutch shaft 5300, reducing the number of motor starts and extending the motor's service life.

[0107] Based on the above description of the stall mechanism 5000, it can be understood that the stall mechanism 5000 serves as the implementation method for electronic unlocking in a passive lock. Furthermore, this application also designs a passive lock including a manual unlocking component to manually open the passive lock when power cannot be supplied to the stall mechanism 5000 or when the stall mechanism 5000 malfunctions.

[0108] Referring to the attached drawings, a manual unlocking component is disposed in the lock housing 1000. The manual unlocking component includes a pull member 7100 and a toggle member 7200. The pull member 7100 is connected to the second end of the second locking movable member 4200, and the toggle member 7200 is connected to the pull member 7100. When the user inserts a key and the key is connected to the toggle member 7200, the user can rotate the toggle member 7200 by the key. The toggle member 7200 then drives the pull member 7100 to move in the second direction. The pull member 7100 then drives the second locking movable member 4200 to move in the second direction, so that the second locking movable member 4200 moves to a position where it is not engaged with the lock cylinder engagement area, thereby releasing the second locking movable member 4200 from locking the lock cylinder shaft.

[0109] Specifically, the end of the actuating member 7200 is provided with an eccentric structure, and the pulling member 7100 is provided with a fourth recessed area, into which the eccentric structure extends. When the user manually rotates the actuating member 7200, the side wall of the eccentric structure abuts against the side wall of the fourth recessed area, and the eccentric structure applies a pushing force to the pulling member 7100. The actuating member 7200 drives the pulling member 7100 to move along the second direction through the eccentric structure, so that the pulling member 7100 drives the second locking movable member 4200 to move along the second direction to a position where it is not engaged with the lock cylinder engagement area 3101.

[0110] It is understandable that the eccentric structure is set as a column in an eccentric position on the end face of the toggle 7200, or the eccentric structure is a cam.

[0111] It should be noted that the second end of the second locking movable member 4200 is movably connected to the pulling member 7100, so that when the passive lock is unlocked electrically, the pulling member 7100 can move the second locking movable member 4200 in the second direction to a position where it does not engage with the lock cylinder engagement area 3101 without interfering with its movement. Specifically, the second end of the second locking movable member 4200 has a recessed movable area on its side, which provides space for the second locking movable member 4200 to move. The movable area also has a sidewall that abuts against the pulling member 7100, allowing the pulling member 7100 to apply a pulling force to the second locking movable member 4200.
