Technical Field

[0001] This application relates to the field of lock technology, and in particular to an emergency unlocking structure, unlocking method, smart cash box lock and smart cash box. Background Technology

[0002] Traditional lock systems have long relied primarily on mechanical lock technology, which offers limited unlocking methods and relatively low security, mainly depending on physical keys for protection. However, with continuous societal development, the demand for both security and convenience has gradually increased, making traditional mechanical lock systems increasingly inadequate in meeting these new needs.

[0003] With the rapid development of electronic technology, electronic combination locks have gradually been applied to lock systems as a modern solution. These electronic combination locks use advanced technologies such as digital passwords and fingerprint recognition to authenticate users and provide more diverse unlocking methods. However, despite the significant progress made in improving security and convenience, electronic combination locks still have some technical limitations in the face of emergencies and main control unit failures.

[0004] Currently, various electronic combination lock systems exist on the market, employing methods such as digital passwords, fingerprints, or card swipes for authentication. These systems offer a high level of security under normal operating conditions. However, many systems do not provide sufficiently reliable backup plans in the event of a main control unit failure or an emergency. Users may face the predicament of being unable to open the locker in a timely manner in emergencies, which is particularly prominent when urgent access to the contents is required.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Please see Figures 1 to 4 :

[0044] This application first provides an embodiment of an emergency unlocking structure, which includes: an emergency unlocking component 101 and an emergency enabling component 102; the emergency enabling component 102 has an emergency working state that enables the emergency unlocking component 101 to work and a prohibited working state that prevents the emergency unlocking component 101 from working; when the emergency enabling component 102 is in the emergency working state, it unlocks and closes the lock by controlling the emergency unlocking component 101.

[0045] This embodiment provides an example of an emergency unlocking structure. The following is a detailed description of this embodiment:

[0046] Emergency unlocking component 101: This is one of the core components of the emergency unlocking structure. It can be a mechanical device, electronic device, or other form of structure used to perform the actual unlocking operation.

[0047] Emergency enabling component 102: This is another key component of the emergency unlocking structure. This component is responsible for controlling the operating state of the emergency unlocking component 101. Specifically, it has two states: emergency operating state and disabled operating state. In the emergency operating state, this component allows the emergency unlocking component 101 to perform unlocking and locking operations; while in the disabled operating state, it disables or prevents the operation of the emergency unlocking component 101.

[0048] Operating Status Control: A key function of the emergency enabling component 102 is to switch the operating status of the emergency unlocking component 101. When the emergency enabling component 102 is in emergency operating status, it allows the emergency unlocking component 101 to perform an unlocking operation. This switching can be achieved in various ways, including mechanical, electronic, or other technologies.

[0049] Unlocking / Unlocking Operation: When the emergency enabling component 102 is in emergency operating state, the unlocking / unlocking operation is achieved by controlling the emergency unlocking component 101. This may include releasing the locked mechanical parts, changing the circuit state, or performing other appropriate operations to ensure that the locked state is reliably released.

[0050] This embodiment provides an emergency unlocking structure with two key components: an emergency unlocking component 101 and an emergency enabling component 102. By cleverly designing the operating state of the emergency enabling component 102, the emergency unlocking component 101 can be controllably activated in an emergency, thereby enabling locking and unlocking. This design ensures the system operates safely and reliably under normal conditions, while also enabling rapid response to emergencies when needed.

[0051] In an optional embodiment, a conventional unlocking component 103 is also included; when the emergency enabling component 102 is in the prohibited working state, the conventional unlocking component 103 is controlled to unlock the device.

[0052] In this optional embodiment, in addition to the emergency unlocking component 101 and the emergency enabling component 102, a conventional unlocking component 103 is also introduced. The following is a detailed description of this optional embodiment:

[0053] Conventional unlocking component 103: This is another component of the unlocking structure used to perform unlocking operations in normal operating mode. Compared to the emergency unlocking component 101, the conventional unlocking component 103 is for use under normal circumstances. It may include conventional locking mechanical parts, electronic unlocking systems, or other unlocking devices.

[0054] When the emergency enabling component 102 is disabled, the system will disable the operation of the emergency unlocking component 101. In this case, unlocking can only be achieved by controlling the regular unlocking component 103. This means that in normal operation mode, the unlocking operation must be performed using the regular unlocking component 103.

[0055] This embodiment introduces a conventional unlocking component 103, giving the system greater flexibility between emergency operating conditions and normal operation modes. In the prohibited operating state, the system can unlock and delock by controlling the conventional unlocking component 103, while in the emergency operating state, it can unlock and delock via the emergency unlocking component 101. This flexibility allows the system to adapt to different operating scenarios and needs.

[0056] In one specific embodiment, the emergency enabling component 102 includes a limiting structure 1021 and an emergency driving structure 1022; the emergency unlocking component 101 includes a receiving structure 1011 corresponding to the limiting structure 1021; the emergency driving structure 1022 controls the limiting structure 1021 to cooperate with the receiving structure 1011 to realize the switching of the working state of the emergency enabling component 102.

[0057] In this specific embodiment, the emergency enabling component 102 includes a limiting structure 1021 and an emergency driving structure 1022, while the emergency unlocking component 101 includes a receiving structure 1011 corresponding to the limiting structure 1021. The following is a detailed description of this embodiment:

[0058] Limiting structure 1021: This is part of the emergency enabling component 102 and may be a mechanical device or an electronic component. The main function of the limiting structure 1021 is to limit or control the range of motion of the emergency enabling component 102. It may have two or more states, one corresponding to the emergency operating state and the other corresponding to the prohibited operating state.

[0059] Emergency drive structure 1022: This is another part of the emergency enable component 102, used to control the state of the limit structure 1021. The emergency drive structure 1022 can drive the movement of the limit structure 1021 by mechanical, electronic or other means, thereby switching the working state of the emergency enable component 102. It can be an activation device responsible for switching the limit structure 1021 from one state to another.

[0060] Receiving structure 1011: This is part of the emergency unlocking component 101 and corresponds to the limiting structure 1021. The receiving structure 1011 can be a mechanical device for receiving or releasing the emergency unlocking component 101 to allow or prevent the unlocking operation.

[0061] The emergency drive structure 1022 controls the movement of the limit structure 1021 to switch the operating state of the emergency enable component 102. When the emergency operating state needs to be activated, the emergency drive structure 1022 adjusts the limit structure 1021 to allow the emergency unlock component 101 to perform an unlocking operation. In the disabled operating state, the limit structure 1021 may be adjusted to disable the emergency unlock component 101, while enabling the regular unlock component 103.

[0062] In one specific embodiment, the limiting structure 1021 is a limiting baffle 02, the emergency drive structure 1022 is an emergency motor 01, and the drive end of the emergency motor 01 is connected to the limiting baffle 02; the receiving structure 1011 is a stop groove 030 provided in the emergency unlocking component 101; the emergency motor 01 drives the limiting baffle 02 to be inserted into or removed from the stop groove 030.

[0063] In this specific embodiment, the limiting structure 1021 is a limiting baffle 02, the emergency drive structure 1022 is an emergency motor 01, and the receiving structure 1011 is a stop groove 030 disposed in the emergency unlocking assembly 101. The following is a detailed description of this embodiment:

[0064] Limiting baffle 02: Limiting baffle 02 is part of the limiting structure 1021 and can be a flat plate or sheet-like object. Its main function is to be controlled during movement to limit the movement of the emergency enabling component 102. In this embodiment, the movement state of the limiting baffle 02 can be twofold: one corresponding to the emergency working state and the other corresponding to the prohibited working state.

[0065] Emergency motor 01: Emergency motor 01 is part of the emergency drive structure 1022 and is responsible for controlling the movement of the limit stop plate 02. It can be an electric motor that controls the position of the limit stop plate 02 through electric drive. The drive end of the motor is connected to the limit stop plate 02, so that the movement of the motor can cause the movement of the limit stop plate 02.

[0066] Stop groove 030: Stop groove 030 is part of receiving structure 1011 and can be provided on emergency unlocking component 101. It can be a groove or recess. This groove is designed to accommodate limit stop plate 02. When limit stop plate 02 is embedded in stop groove 030, it can prevent or release emergency unlocking component 101 to realize the locking and unlocking operation.

[0067] Control of Emergency Motor 01: Emergency Motor 01 is connected to Limit Stop 02 via its drive end, and the movement of Limit Stop 02 is controlled electrically. When Emergency Motor 01 starts, it causes Limit Stop 02 to engage with Stop Groove 030, thereby preventing the unlocking operation of Emergency Unlocking Assembly 101. Conversely, when Emergency Motor 01 stops, Limit Stop 02 may be pulled away from Stop Groove 030, allowing Emergency Unlocking Assembly 101 to unlock.

[0068] Other specific embodiments provided in this application are described below:

[0069] See Figures 1 to 4 This application also provides an embodiment of an emergency unlocking structure, which includes:

[0070] The system comprises an emergency motor 01, a limit stop 02, an end face gear 03, a drive gear 04, a main motor 05, a driven structure 06, and a locking rod 07. The drive gear 04 is connected to the main motor 05 and is also powered by the end face gear 03 and the driven structure 06. The locking rod 07 is connected to the driven structure 06. The main motor 05 drives the drive gear 04 to rotate, and the drive gear 04 drives the locking rod 07 to move through the driven structure 06. The end face gear 03 has a stop groove 030. The limit stop 02 is connected to the emergency motor 01 and has a locking hole 033. The emergency motor 01 drives the limit stop 02 to engage or disengage from the stop groove 030.

[0071] The following is a description of each component of this embodiment:

[0072] Main motor 05: The main motor 05 is responsible for the locking and unlocking functions under normal conditions and is connected to the system through the drive gear 04.

[0073] Emergency motor 01: Emergency motor 01 is specifically used to drive limit stop plate 02.

[0074] Drive gear 04: Drive gear 04 is connected to the main motor 05, and also to the end face gear 03 and the driven structure 06, and plays the role of transmitting power.

[0075] Driven structure 06: Driven structure 06 controls the position of locking lever 07 through the movement of drive gear 04.

[0076] Locking lever 07: Locking lever 07 is connected to driven structure 06 and is a key component of the locking mechanism.

[0077] End face gear 03: The end face gear 03 is provided with a stop groove 030, and the movement of the locking rod 07 is controlled by the rotation of the drive gear 04.

[0078] Limiting plate 02: The limiting plate 02 is connected to the emergency motor 01 and is driven by the emergency motor 01 to engage or disengage from the stop groove 030 on the end face gear 03.

[0079] Under normal circumstances, the main motor 05 controls the movement of the driven structure 06 through the drive gear 04, thereby controlling the position of the locking rod 07 and realizing the locking and unlocking of the lock.

[0080] In an emergency, the user terminal sends an emergency unlocking command to the lock, and the main controller 001 responds to the command. The main controller 001 controls the emergency motor 01, causing the limit stop 02 to disengage from the stop groove 030, unlocking the end gear 03. The user inserts a physical key into the lock hole 033 and rotates the end gear 03. Since the stop groove 030 is unlocked, the end gear 03 can rotate freely. The rotation of the end gear 03 is transmitted to the driven structure 06 through the drive gear 04, thereby controlling the position of the lock rod 07 and unlocking the lock. After the user completes the emergency unlocking operation, the main controller 001 can re-control the emergency motor 01 to re-engage the limit stop 02 into the stop groove 030, locking the end gear 03.

[0081] In this embodiment, by introducing an authorization mechanism, the system can ensure that emergency unlocking can only be performed with valid authorization. This improves the overall security of the lock and prevents unauthorized access.

[0082] This structure offers multiple unlocking methods, including normal electric unlocking and emergency physical key unlocking. This design allows for selection of the most suitable unlocking method in different scenarios. Emergency motor 01 serves as a backup power source, increasing system reliability. In the event of main motor 05 failure or unavailability, emergency motor 01 can provide a backup unlocking method. Emergency unlocking is controlled by the main controller 001 and can be authorized via remote commands or other security means. This centralized control increases the controllability and security of the emergency unlocking process. Providing multiple unlocking methods allows users to choose the most suitable or convenient method, thus improving user-friendliness. The authorization mechanism for controlling emergency unlocking effectively prevents unauthorized intruders from attempting to physically break the lock. This enhances the lock's resistance to attack.

[0083] In the above embodiments, during authorized emergency unlocking, the end face gear 03 is rotated to drive the drive gear 04 to rotate, thereby driving the driven structure 06 to move, and finally driving the lock rod 07 to move. In an optional embodiment, under normal circumstances, the end face gear 03 may not mesh with the drive gear 04, that is, under normal circumstances, the rotation of the drive gear 04 will not drive the end face gear 03 to rotate, which means that the power transmission between the end face gear 03 and the drive gear 04 is unidirectional.

[0084] In this application, there are multiple ways to achieve unidirectional power transmission between the end face gear 03 and the drive gear 04; see reference [link / reference needed]. Figure 5 and Figure 6 Here is an optional embodiment:

[0085] In this optional embodiment, the end face gear 03 includes:

[0086] The gear 031 and the wheel body 032 are provided. The gear 031 is disposed on the wheel body 032. The gear 031 of the wheel body 032 is provided with a clearance groove 0310. Except for the clearance groove 0310, the gear 031 is provided with end face teeth 0311 for meshing with the drive gear 04.

[0087] Structure of end face gear 03:

[0088] Wheel body 032: The end face gear 03 includes a wheel body 032, which is the main structure of the entire end face gear 03.

[0089] Tooth 031: Tooth 031 is provided on wheel body 032 and is responsible for meshing with drive gear 04 to transmit power.

[0090] End face teeth 0311: End face teeth 0311 are located on tooth portion 031, except at a specific position (at the clearance groove 0310). These end face teeth 0311 mesh with the teeth of the drive gear 04 to transmit power.

[0091] Alternating groove 0310: An alternating groove 0310 is provided on the tooth 031 of the wheel body 032 to restrict the meshing of the end face gear 03 and the drive gear 04 at a specific position. When the end face gear 03 rotates to the position of the alternating groove 0310, the end face tooth 0311 will no longer mesh with the tooth of the drive gear 04, realizing unidirectional power transmission.

[0092] Under normal circumstances, the drive gear 04 is located in the clearance groove 0310 of the end face gear 03, and the end face gear 03 will no longer mesh with the drive gear 04, thus interrupting the one-way power transmission. At this time, normal online unlocking is achieved through the main motor 05, and no power is transmitted to the end face gear 03.

[0093] In an emergency, the end face teeth 0311 of the end face gear 03 mesh with the drive gear 04, allowing forward power transmission. In this case, the drive gear 04 is driven by the end face gear 03, thereby realizing the power transmission from the end face gear 03 to the driven structure 06 and controlling the position of the locking lever 07.

[0094] When emergency unlocking is required, the user terminal sends an authorization command to the lock, and the main controller 001 releases the limit stop plate 02 via the emergency motor 01. The user inserts a physical key into the keyhole 033 and rotates the end face gear 03, causing the drive gear 04 to disengage from the position of the clearance groove 0310. At this time, the drive gear 04 will mesh with the end face gear 03, thus enabling the movement of the lock rod 07 to be controlled by the physical key.

[0095] In an optional embodiment, the lock hole 033 is located at the center of the wheel body 032.

[0096] The keyhole 033 is located at the center of the wheel body 032 of the end face gear 03, that is, in the central area around the teeth 031. This design makes the keyhole 033 the center point of the end face gear 03, coinciding with the rotation axis of the wheel body 032. When the user needs to unlock the car with a physical key, he / she can insert the physical key into the keyhole 033, which directly connects to the central area of ​​the end face gear 03.

[0097] In an optional embodiment, a protrusion 0321 is further included, which is disposed in the middle of the wheel body 032, and the stop groove 030 is formed on the protrusion 0321.

[0098] A protrusion 0321 is located at the center of the wheel body 032, specifically at the center of the diameter of the end face gear 03. In this design, the protrusion 0321 serves to support the stop groove 030. The stop groove 030 is provided on the protrusion 0321 and can be a recessed groove on the protrusion 0321. The presence of the stop groove 030 restricts the meshing of the end face gear 03 and the drive gear 04 under normal conditions. When the stop groove 030 cooperates with the limit stop 02, it interrupts the unidirectional power transmission.

[0099] In an optional embodiment, the driven structure 06 includes a worm gear 061 and a driven gear 062, the driven gear 062 being disposed on the worm gear 061, the worm gear 061 being connected to the locking rod 07, and the driven gear 062 meshing with the driving gear 04.

[0100] The worm gear 061 is a helical structure, typically spiral-shaped, and is connected to the driven gear 062. The worm gear 061 is a very efficient transmission device used to convert rotary motion into linear motion.

[0101] Driven gear 062 is mounted on worm gear 061. The power of driven gear 062 is transmitted to locking rod 07 by worm gear 061, thereby realizing the unlocking and locking of the lock.

[0102] Under normal circumstances, the drive gear 04 transmits power to the driven gear 062. The driven gear 062 then directly drives the worm gear 061 to rotate, and the worm gear 061 converts the rotational motion into the linear motion of the locking lever 07.

[0103] In an emergency, the user rotates the end face gear 03 using a physical key. The rotation is transmitted to the driven gear 062 via the drive gear 04. This causes the worm gear 061 to rotate, thereby driving the locking lever 07 to produce linear motion and controlling the position of the locking lever 07.

[0104] The design utilizes the structure of the worm gear 061 and the driven gear 062 to achieve flexible switching between electric and physical key operation. Even when electric drive is limited, the driven gear 062 can still be effectively controlled by physical means, thus ensuring normal lock operation.

[0105] Furthermore, the worm gear 061 is a double-ended worm gear, and both ends of the double-ended worm gear are connected to locking rods 07.

[0106] In this further embodiment, locking rods 07 are connected to both ends of the double-ended worm gear. This means that the two helical ends of the worm gear 061 are connected to the two locking rods 07 respectively. A driven gear 062 is provided in the middle part of the double-ended worm gear for transmitting rotational motion.

[0107] By using a double-ended worm gear, a structure capable of simultaneously controlling both locking levers 07 was achieved. This design provides a higher level of safety and control while maintaining system complexity.

[0108] In an optional embodiment, the drive gear 04 is a double gear.

[0109] In this embodiment, a double gear means that two gears are connected together, which can be on the same shaft. These two gears can have different numbers of teeth, diameters, or modules. The design of a double gear can provide more complex transmission ratios and increase control over power transmission.

[0110] The design of the double gears allows one gear, for example, a smaller gear, to mesh with the end face gear 03, while the other gear meshes with the driven gear 062.

[0111] In an optional embodiment, one side of the end face gear 03 is connected to the lock cylinder 002, and the lock hole 033 communicates with the keyhole of the lock cylinder 002.

[0112] In this embodiment, one side of the end face gear 03 is connected to the lock cylinder 002 via a specific connection structure. This can be achieved through a shaft, coupling, or other suitable connection method.

[0113] In an emergency, lock cylinder 002 receives the physical key. When lock cylinder 002 receives the appropriate physical key, the user can rotate the physical key, and simultaneously the end face gear 03 rotates, driving the driven gear 062. This unlocks the lock.

[0114] By connecting one side of the end face gear 03 to the lock cylinder 002, and making the keyhole 033 connected to the keyhole of the lock cylinder 002, the design achieves an organic combination of electric unlocking and physical key unlocking. This design maintains the electric unlocking function while providing a backup unlocking method with a physical key.

[0115] In an optional embodiment, the keyhole 033 is rectangular in shape.

[0116] This optional embodiment, by employing a rectangular keyhole 033, takes into account the shape of the physical key, providing a highly adaptable and easy-to-use physical unlocking method. This design aims to ensure proper insertion of the physical key and to effectively control the rotation of the end face gear 03.

[0117] This application also provides a smart cash box lock, which is equipped with any of the above-mentioned emergency unlocking mechanisms.

[0118] This application also provides a smart cash box equipped with any of the above-mentioned emergency unlocking mechanisms.

[0119] See Figure 7 This application also provides an unlocking method for controlling any of the above-mentioned emergency unlocking structures. The following is a detailed description of an embodiment of this unlocking method, which includes:

[0120] S101, Receive emergency unlocking authorization command sent by authorized user;

[0121] In this step, the system receives an emergency unlocking authorization command from the authorized user through the corresponding interface or communication channel. This command may be a signal sent by the user via a physical button, wireless remote control, mobile application, or other authorization means, indicating that the authorized user authorizes emergency unlocking.

[0122] S102. In response to the emergency unlocking authorization command, activate the emergency enabling component to switch to emergency working state;

[0123] Upon receiving an emergency unlocking authorization command, the system immediately responds and activates the emergency enabling component. This may include switching the emergency enabling component to emergency operating state via electronic control signals or mechanical devices. In this state, the emergency enabling component allows or enables the emergency unlocking component to perform unlocking operations.

[0124] If the emergency enable component is an electronic device, it can be switched to emergency operating mode by controlling the state of an electronic switch or trigger.

[0125] If the emergency enable component is a mechanical device, it can be put into emergency working state by driving a motor or performing other mechanical operations.

[0126] S103. When a reset signal is received, the emergency enable component is triggered to reset to the disabled state.

[0127] The system not only responds to emergency unlocking commands but also possesses security and controllability features. In this step, the system listens for a reset signal. Once a reset signal is received, the system triggers a corresponding mechanism to reset the emergency enabling component to a disabled state. This means the emergency unlocking component will be disabled, ensuring the system returns to normal operation when emergency unlocking is no longer needed.

[0128] In this step, the system listens for the received reset signal. If the reset signal is a signal indicating unlocking, the system triggers the corresponding mechanism to reset the emergency enable component to a disabled state. If the reset signal is a manually sent reset signal, the system also triggers the corresponding mechanism to reset the emergency enable component to a disabled state. This step allows the system to flexibly perform appropriate reset operations based on the different types of reset signals received, ensuring that the system's state is properly maintained.

[0129] If the reset signal is the signal that unlocking is complete, the system can perform the following operations:

[0130] Verify that the unlocking operation was successfully completed.

[0131] If successful, the emergency enable component will be reset to a disabled state.

[0132] If it fails, appropriate corrective measures may need to be taken or a warning may need to be issued.

[0133] Specifically, in one embodiment, the emergency enabling component includes an emergency driving structure and a limiting structure, and the emergency unlocking component includes a receiving structure. The step of activating the emergency enabling component to switch to emergency operating state in response to the emergency unlocking authorization command, as described in the foregoing embodiment, includes:

[0134] In response to the emergency unlocking authorization command, the emergency drive structure is controlled to drive the limiting structure to disengage from the receiving structure.

[0135] In this specific embodiment, the emergency enabling component includes an emergency driving structure and a limiting structure, while the emergency unlocking component includes a receiving structure.

[0136] Specific implementation steps:

[0137] Receive emergency unlocking authorization command:

[0138] The system receives emergency unlocking authorization commands from authorized users through corresponding interfaces or communication modules. These commands can be signals sent via remote control, mobile applications, or other authorized means.

[0139] Activate the emergency drive structure:

[0140] In response to an emergency unlocking authorization command, the system activates the emergency drive mechanism. This can be achieved through electronic control, electric motor drive, or other appropriate mechanical operation to ensure the emergency drive mechanism is ready to perform the next step.

[0141] Controlling the coordination between the emergency drive structure, the limit structure release mechanism, and the receiving structure:

[0142] The system controls the movement of the emergency drive structure to disengage the limiting structure from the receiving structure. This may include moving the limiting structure to a position that allows the emergency unlocking component to operate, such as unlocking, releasing, or disengaging the receiving structure.

[0143] Switch to emergency working mode:

[0144] By cooperating with the release and receiving structures, the emergency unlocking component can perform an unlocking operation in an emergency operating state. This may include releasing locked mechanical parts, changing the circuit state, or performing other appropriate operations.

[0145] More specifically, the emergency drive structure is an emergency motor, the limiting structure is a limiting baffle, and the receiving structure is a stop groove. Therefore, this specific embodiment is as follows:

[0146] The emergency motor is controlled to drive the limit stop plate to rotate, so that the limit stop plate leaves the stop groove.

[0147] In this embodiment, the limit stop is rotated to a position under the control of the emergency motor, causing it to disengage from the stop groove. This process may include lifting the limit stop from the groove to release the engagement between the limit stop and the stop groove, thereby allowing the emergency unlocking component to freely perform the unlocking operation.

[0148] Based on the foregoing embodiments, when a reset signal is received, triggering the emergency enable component to reset to a disabled state includes:

[0149] When a reset signal is received, the emergency motor is controlled to drive the limit stop plate to rotate, so that the limit stop plate is embedded in the stop groove.

[0150] In this embodiment, upon receiving a reset signal, the system controls the movement of the emergency motor, causing it to drive the limit stop plate to rotate. The purpose of this control is to move the limit stop plate from its current position to a new position, so that it is embedded in the stop groove.

[0151] Controlled by the emergency motor, the limit stop plate rotates to a position where it engages with the stop groove. This process may involve lowering the limit stop plate from a higher position into the stop groove to ensure that the limit stop plate and the stop groove are engaged again.

[0152] Once the limit stop plate engages with the stop groove, the system triggers the emergency enable component to reset to the inoperable state. This may include stopping the movement of the emergency motor, or ensuring the emergency enable component is inoperable through other mechanisms.

[0153] In this embodiment, upon receiving a reset signal, the system controls the movement of the emergency motor to embed the limit stop into the stop groove, thereby resetting the emergency enabling component to a disabled state. This design ensures that the system can be quickly restored to a normal, disabled state via a reset signal when needed.

[0154] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
