These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0029] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0030] Existing unlocking control boxes typically rely on hydraulic systems for unlocking. Specifically, power is transmitted through hydraulic cylinders or gear sets to move the bolt and unlock. However, existing unlocking control boxes are prone to failure in low-temperature environments, resulting in poor environmental adaptability.

[0031] In view of this, this application provides an unlocking control box that effectively solves the failure problems caused by low-temperature solidification and leakage of hydraulic oil in existing technologies by replacing the traditional hydraulic system with mechanical transmission, significantly improving environmental adaptability. Specifically, the drive device directly drives the rope component to perform a pulling motion, avoiding the failure problem caused by hydraulic oil solidification at low temperatures. Furthermore, the design of the box body and the through hole combined with mechanical transmission can reduce maintenance requirements and ensure stable operation of the unlocking control box in low-temperature and harsh environments, thereby significantly improving reliability and service life.

[0032] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings:

[0033] refer to Figures 1 to 3 The unlocking control box 1 provided in this application includes a box body 10, a drive device 20, and a rope component 30. The box body 10 serves as the basic support and protective structure for the unlocking control box 1. The box body 10 has a receiving cavity 11, which provides installation space for the drive device 20, ensuring that the moving parts of the drive device 20 operate stably within a limited range. The box body 10 has a through hole 12 communicating with the receiving cavity 11.

[0034] At least a portion of the drive unit 20 is movably disposed within the receiving cavity 11. Alternatively, the entire structure of the drive unit 20 is movably disposed within the receiving cavity 11. The drive unit 20 provides initial rotational power through an internal drive element 21 (such as a motor) and converts the rotational motion of the drive element 21 into linear motion through a transmission mechanism 22 (such as a worm gear mechanism).

[0035] The rope member 30 can be threaded through the through hole 12. One end of the rope member 30 can be located inside the receiving cavity 11. Furthermore, the rope member 30 is fixedly connected to the drive device 20 to achieve motion transmission. The other end of the rope member 30 can extend outside the receiving cavity 11. Thus, the rope member 30 located outside the receiving cavity 11 can be connected to the object to be driven. The object to be driven can be a door lock's latch, locking actuator, or other components that require a pulling motion to open or close the lock. The drive device 20 is adapted to drive the rope member 30 to perform a pulling motion to open or close the lock.

[0036] Understandably, by replacing the traditional hydraulic system with mechanical transmission, the failure problems caused by low-temperature solidification and leakage of hydraulic oil in existing technologies are effectively solved, significantly improving environmental adaptability. Specifically, the drive device 20 directly drives the rope component 30 to perform a pulling motion, avoiding the failure problem caused by the solidification of hydraulic oil at low temperatures. Furthermore, the design of the box body 10 and the through hole 12, combined with mechanical transmission, can reduce maintenance requirements and ensure the stable operation of the unlocking control box 1 in low-temperature and harsh environments, thereby significantly improving reliability and service life.

[0037] In one possible implementation, the drive device 20 includes a drive member 21 and a transmission mechanism 22. The drive member 21 may be fixed within the receiving cavity 11. The transmission mechanism 22 may be connected to both the drive member 21 and the rope member 30. The drive member 21 can drive the rope member 30 to move via the transmission mechanism 22. For example, the drive member 21 may be a motor. The transmission mechanism 22 may be a helical inclined plane push rod structure or a worm gear transmission structure.

[0038] In one possible implementation, the drive element 21 has a rotatable output shaft. The output shaft is the output end of the rotational power of the drive element 21, and is typically a cylindrical metal rod whose axis coincides with the rotor axis of the drive element 21.

[0039] The transmission mechanism 22 includes a transmission rod 221 and a slider 222. The transmission rod 221 can be connected to the output shaft to transmit the rotational power of the output shaft of the drive member 21 to the transmission rod 221, causing it to rotate synchronously. The slider 222 can be driven by the transmission rod 221. The slider 222 is adapted to convert the rotation of the transmission rod 221 into its own movement. In this embodiment, the slider 222 is adapted to convert the rotation of the transmission rod 221 into vertical movement. The rope member 30 can be connected to the slider 222 to transmit the vertical movement of the slider 222 to the driven body, realizing the opening or closing action of the lock.

[0040] Optionally, the transmission engagement between the slider 222 and the transmission rod 221 can be achieved through a threaded pair structure. Specifically, the outer wall of the transmission rod 221 can be machined with external threads (such as trapezoidal threads or triangular threads), and the lead of the threads can be designed according to the required moving speed of the slider 222. The axis of the transmission rod 221 is arranged vertically (consistent with the moving direction of the slider 222). A transmission hole can be formed inside the slider 222, and the inner wall of the transmission hole is machined with internal threads that match the external threads of the transmission rod 221 (the pitch and thread angle are consistent with the external threads). The transmission hole of the slider 222 and the transmission rod 221 form a threaded pair engagement through the internal and external threads.

[0041] In the specific implementation process, when the output shaft of the driving component 21 drives the transmission rod 221 to rotate (assuming the transmission rod 221 rotates clockwise), the slider 222 is subjected to axial thrust due to the meshing of its internal thread with the external thread of the transmission rod 221. When the output shaft of the driving component 21 drives the transmission rod 221 to rotate clockwise, the external thread of the transmission rod 221 meshes tightly with the internal thread of the slider 222, and the helix angle of the thread generates an axial thrust along the axis of the transmission rod 221, pushing the slider 222 to move downward along the axis of the transmission rod 221; when the transmission rod 221 rotates counterclockwise, the helix angle of the thread acts in the opposite direction, the direction of the axial thrust changes, and the slider 222 moves upward along the axis of the transmission rod 221.

[0042] In one possible implementation, the axis of the output shaft can be perpendicular to the axis of the transmission rod 221. A worm gear 211 is provided on the output shaft. The transmission rod 221 includes a gear portion 223. The gear portion 223 can be located at the top of the transmission rod 221. The gear portion 223 can mesh with the worm gear 211. Thus, the worm gear 211 on the output shaft and the transmission rod 221 can form a worm gear transmission structure. The tooth profile of the worm gear can be conjugate with that of the gear portion 223. The gear portion 223 and the transmission rod 221 can be integrally formed or use a cast structure (the gear ring of the gear portion 223 can be a copper alloy, and the core of the gear portion 223 and the transmission rod 221 are made of steel, fixed by interference fit or welding). The copper alloy gear ring can reduce meshing noise and reduce wear.

[0043] Understandably, the vertical arrangement of the output shaft and transmission rod 221 effectively utilizes the internal space of the housing 10 (e.g., the output shaft extends horizontally to the side of the housing 10, and the transmission rod 221 is arranged vertically in the middle of the housing 10). This avoids the long axial occupation of traditional parallel shaft drives, making it suitable for the miniaturized design of the unlocking control box 1. Furthermore, when the worm gear transmission structure ensures that the worm 211 stops rotating and the worm wheel is locked when the drive component 21 is de-energized, the position of the rope component 30 is fixed through the cooperation of the transmission rod 221 and the slider 222, preventing the lock tongue from accidentally retracting due to external force and effectively ensuring the safety of the lock.

[0044] In one possible implementation, the outer wall of the transmission rod 221 is provided with external threads. The slider 222 is provided with a transmission hole, and the inner wall of the transmission hole is provided with internal threads. The transmission rod 221 can pass through the slider 222, and the transmission rod 221 and the slider 222 are threaded together by the internal and external threads, allowing the slider 222 to move along the axis of the transmission rod 221. The axis of the transmission rod 221 can be parallel to the axis of the through hole 12.

[0045] Understandably, the external thread on the outer wall of the transmission rod 221 and the internal thread on the inner wall of the transmission hole of the slider 222, through threaded engagement, precisely convert the rotational motion of the transmission rod 221 into the linear movement of the slider 222 along the axis of the transmission rod 221, achieving efficient conversion of the power output form of the drive device 20. Simultaneously, the design of the axis of the transmission rod 221 being parallel to the axis of the through hole 12 ensures that the direction of movement of the slider 222 is consistent with the direction of pull of the rope component 30, avoiding rope offset or jamming due to directional deviation, improving the stability and accuracy of power transmission, and ultimately ensuring the reliable execution of the lock's opening or closing actions.

[0046] In one possible implementation, the inner wall of the receiving cavity 11 is provided with a groove, and the slider 222 is slidably disposed in the groove.

[0047] In one possible implementation, the slider 222 is further provided with a connecting hole. The rope component 30 includes a rope body and a first connector. The rope body can pass through the connecting hole. The first connector of the rope component 30 can be located at one end of the rope body within the receiving cavity 11, and the first connector is used to engage with the slider 222. Optionally, the cross-sectional shape of the connecting hole can be designed as circular (to fit a cylindrical rope body) or rectangular (to fit a flat rope body), with the hole diameter slightly larger than the diameter of the rope body to allow for assembly clearance. The first connector can be an enlarged structure at one end of the rope body within the receiving cavity 11, and its shape matches the connecting hole (e.g., circular, square, or barbed). The first connector can be a spherical head, a barbed head, a cylindrical head, etc.

[0048] In one possible implementation, the connecting hole includes a first segment and a second segment. The first and second segments can be sequentially distributed along the axis of the transmission rod 221. Further, the first segment is located on the side of the second segment away from the through hole 12. The cross-sectional area of ​​the first segment is larger than that of the second segment. The rope body is located in the second segment, and the first connector is engaged in the first segment. Optionally, the shape of the first connector can be a spherical head, a barbed head, a cylindrical head, etc. The shape of the first connector can be determined according to actual design requirements, and this application does not impose any limitations.

[0049] Understandably, the diameter (or cross-sectional area) of the rope body matches the second hole section to allow the rope body to pass freely. However, the cross-sectional area of ​​the first connector is larger than that of the second hole section, preventing it from passing through the second hole section in the reverse direction. Therefore, when the first connector enters the first hole section, it can be limited by the transition surface between the first and second hole sections, forming a "one-way snap-fit" structure. That is, the rope component 30 cannot exit from the receiving cavity 11 towards the through hole 12, thereby preventing the rope component 30 from falling off the slider 222 due to tension during the pulling process.

[0050] In one possible implementation, the cross-sectional area of ​​the first hole gradually decreases along the axis of the transmission rod 221 and in the direction close to the through hole 12.

[0051] In the specific implementation process, when the slider 222 moves along the axis of the transmission rod 221 (e.g., upward or downward), the first connector, being limited, will move synchronously with the slider 222. At this time, the first connector transmits the pushing or pulling force of the slider 222 to the rope body through the transition surface between the first and second hole sections. If the slider 222 moves away from the through hole 12 (e.g., upward), the transition surface pushes the first connector to move synchronously, the rope body is pulled (shortening the length outside the receiving cavity 11), and the locking tongue is opened. If the slider 222 moves closer to the through hole 12 (e.g., downward), the transition surface pulls the first connector to move synchronously, the rope body relaxes (extending the length outside the receiving cavity 11), and the locking tongue closes under the action of the spring force.

[0052] In one possible implementation, the unlocking control box 1 further includes a stroke adjustment device 40. The stroke adjustment device 40 may be disposed within the receiving cavity 11. The stroke adjustment device 40 is used to adjust the travel of the slider 222.

[0053] Understandably, the introduction of the stroke adjustment device 40 significantly improves the versatility and reliability of the unlocking control box 1. The stroke adjustment device 40 allows the unlocking control box 1 to adapt to various scenario requirements. Different locks (such as home smart locks, car door locks, and industrial equipment locks) have significantly different bolt strokes. By adjusting the stroke of the slider 222, the movement requirements of different locks can be precisely matched, avoiding excessive stretching and breakage of the rope component 30 or damage to the bolt due to impact, or insufficient stroke resulting in the bolt not fully opening / closing. Furthermore, after long-term use, components such as the threaded pair of the transmission rod 221 and the slider 222 may experience wear, leading to a shortened actual stroke. The stroke adjustment device 40 can dynamically correct stroke deviations, extending the service life of the control box.

[0054] In one possible implementation, a fixed seat 50 is provided within the receiving cavity 11. The stroke adjustment device 40 includes a swing block 41. The swing block 41 has a connecting end 411 and a limiting end 412. The connecting end 411 of the swing block 41 is hinged to the fixed seat 50. The limiting end 412 of the swing block 41 can move between a first position and a second position. In the first position, the limiting end 412 can be offset from the movement path of the slider 222. In the second position, the limiting end 412 can be on the movement path of the slider 222 and limit the slider 222.

[0055] Understandably, the connecting end 411 of the swing block 41 is rotatably connected to the fixed base 50 via a hinge, allowing its limiting end 412 to move between a first position and a second position around the hinge axis. When the limiting end 412 is in the first position, it is completely offset from the movement path of the slider 222, allowing the slider 222 to move freely to its maximum stroke. When the limiting end 412 switches to the second position, it extends into the movement path of the slider 222, forming a physical block. When the slider 222 moves to this position, it is intercepted by the limiting end 412 and cannot continue to move, thus shortening the actual stroke.

[0056] In this way, the movement range of slider 222 can be flexibly adjusted through simple swing operation, which can not only adapt to the different stroke requirements of different locks, but also compensate for the stroke deviation caused by mechanical wear after long-term use, and avoid problems such as rope breakage and incomplete lock tongue operation caused by excessive or insufficient stroke, thus significantly improving the versatility and reliability of unlocking control box 1.

[0057] In one possible implementation, the unlocking control box 1 further includes a direction adjustment device 70. The direction adjustment device 70 may be located on the outside of the box body 10. The direction adjustment device 70 is used to adjust the pulling direction of the rope member 30.

[0058] In one possible implementation, the direction adjustment device 70 includes a support member, a wheel, and a constraint structure. The wheel can be fixed to the support member. The wheel has grooves formed along its circumference. The constraint structure can be provided on the support member. Multiple constraint structures can be distributed circumferentially along the wheel. A rope member 30 can be wound around at least a portion of the grooves and cooperates with at least a portion of the constraint structure. The constraint structure is used to constrain the rope member 30 within the grooves.

[0059] Understandably, the pulling direction is adjusted by utilizing the change in the rope's path as it winds around the wheel, through the synergistic effect of the wheel's grooves and the constraint structure. The wheel is fixed to the support, and its circumferential grooves provide a guide path for the rope. The portion of the rope wound around the grooves conforms to the circumferential surface of the wheel. Constraint structures (such as limiting protrusions, baffles, or elastic clips) distributed along the circumference of the wheel constrain the rope within the grooves, preventing it from detaching from the wheel. When adjusting the direction, the contact position between the rope's entry end and the wheel determines its winding angle. By limiting the rope's position within the grooves, the constraint structure ensures that it always moves along the wheel's contour, preventing slippage or deviation, thereby stably changing the rope's pulling direction to adapt to the needs of the driven object in different positions.

[0060] In one possible implementation, the direction adjustment device 70 further includes a first sleeve and a second sleeve. The first sleeve can be connected between the support member and the housing 10. The second sleeve can be connected to one side of the support member. Specifically, the second sleeve can be connected to the side of the support member away from the housing 10 along the extension path of the rope member 30. The second sleeve can be arranged at an angle to the first sleeve. The angle between the first sleeve and the second sleeve can be determined according to actual needs, and this application does not impose any limitations. The rope member 30 can be sequentially threaded through the first sleeve, the wheel groove, and the second sleeve. The first sleeve and the second sleeve can provide protection for the rope member 30.

[0061] In one possible implementation, the unlocking control box 1 further includes a control device 60. The control device 60 may be located within the box body 10. The control device 60 is electrically connected to the drive device 20. The control device 60 is used to control the operating state of the drive device 20. The control device 60 is typically an electronic module integrating signal reception, processing, and command output; specific types may include a signal reception and processing module or an MCU module. The control device 60 needs to be electrically connected to a power supply module (not shown in the figure, but it can also be located in the unlocking control box 1). The control device 60 is electrically connected to the signal transmitting module and the drive device 20 (such as the drive unit 21) via circuits or wires. For example, the signal receiving and processing module is connected to the power supply module (providing operating power) and the signal transmitting module (receiving wireless remote control or GSM card commands) via circuits, and is connected to the actuators such as the motor of the drive device 20 via a power-on / off action module, forming a closed-loop circuit of "signal input-processing-output control".

[0062] The control device 60 generates control signals by receiving external signals (such as wireless remote control commands, GSM card commands, inward door opening trigger signals, etc.) to drive the drive device 20 into different working states. For example, when receiving an unlocking command from a wireless remote control or mobile phone, the control device 60 sends an electrical signal to the drive component 21, driving its output shaft to rotate. This rotates the slider 222 via the transmission mechanism 22, and the rope component 30 pulls to unlock the door. When a locking command is detected or there is no operation, the control device 60 stops supplying power, and the drive component 21 remains stationary due to the self-locking characteristic of the transmission mechanism 22, maintaining the locked state of the lock.
