Description

Technical Field

[0001] This application relates to the field of lock technology, and more specifically, to a door control lock. Background Technology

[0002] Access control systems are widely used as a means of prevention and management, especially in scenarios such as power systems and rail transit systems where room doors, fire doors, iron gates, glass doors, and other doors that need to be locked.

[0003] Access control systems are equipped with emergency unlocking mechanisms to allow for evacuation and escape in case of equipment malfunction or emergency. Current emergency unlocking methods typically involve rotating the lock cylinder using an unlocking device (such as a computer key or mechanical key) to switch the clutch module in the door lock from a disengaged state to an engaged state. This allows the handle in the clutch module to connect with the bolt via other structural components. However, the handle must be in a designated position during the switch to the unlocked state to prevent interference between the clutch module components. If the handle is not in the designated position during an emergency unlock, the lock cylinder will force the clutch module to switch to the engaged state, potentially damaging the clutch module and other structural components of the door lock. Summary of the Invention

[0004] This application provides a door lock that can reduce the risk of damage to the clutch module and other structural components in the door lock when the handle is not in a designated position for emergency unlocking.

[0005] This application provides a door control lock, including a first panel assembly and a latch assembly. The first panel assembly includes a first lock box and a first motor unlocking module, a first clutch module, and a first emergency unlocking module disposed within the first lock box. The first motor unlocking module is used to unlock the access control upon receiving an electric unlocking command. The first clutch module includes a first handle, a first handle shaft, a first clutch pivot, a first clutch pin, and a first clutch spring. The first handle is mounted on the first lock box, the first handle shaft is connected to the first handle, the first clutch pin is mounted on the first handle shaft, the first clutch pivot is drivenly connected to the latch assembly and has a first clearance portion corresponding to the first clutch pin, and the first handle shaft has a first position allowing the first clutch pin to insert into the first clearance portion and a second position causing the first clutch pin to be misaligned with the first clearance portion. The first emergency unlocking module includes a first lock cylinder, a first drive mechanism, and a first elastic mechanism, the first elastic mechanism being connected to the first drive mechanism and the first clutch pin. When the first lock cylinder is in the first position and rotated, the first drive mechanism and the first elastic mechanism drive the first clutch pin to compress the first clutch spring and insert it into the first clearance part, so that the door lock is in an emergency unlocking state; when the first lock cylinder is in the second position and rotated, the first drive mechanism moves and the first elastic mechanism stores force, so that when the first handle shaft moves to the first position, it drives the first clutch pin to insert into the first clearance part.

[0006] Specifically, when the first handle shaft is in the first position, the first clutch pin is aligned with the first clearance part. At this time, the first lock cylinder is rotated so that the first lock cylinder can drive the first drive mechanism and the first elastic mechanism to drive the first clutch pin to compress the first clutch spring and insert it into the first clearance part. This allows the first handle to be connected to the lock tongue assembly through the first handle shaft and the first clutch pivot, so that the door lock is in an emergency unlocking state. When the first handle shaft is in the second position, the first clutch pin and the first clearance part are misaligned. At this time, rotating the first lock cylinder causes the first lock cylinder to tend to drive the first drive mechanism and the first elastic mechanism to drive the first clutch pin. However, since the first clutch pin is not aligned with the first clearance part, the first clutch pin will interfere with the first clutch shaft during the movement. At this time, the first elastic mechanism is compressed to store force, reducing the risk of damage to the first clutch pin, the first drive mechanism and the first elastic mechanism due to forced movement. Then, the first handle is rotated to drive the first handle shaft from the second position to the first position. The first elastic mechanism can drive the first clutch pin to insert into the first clearance part, so that the first handle can be connected to the lock tongue assembly through the first handle shaft and the first clutch shaft, so that the door lock is in an emergency unlocking state.

[0007] In the above technical solution, by setting a first elastic mechanism, when the first handle is in the second position and the first lock cylinder is rotated, the first elastic mechanism can store force, thereby reducing the risk of damage to the first clutch pin and the first drive mechanism due to forced movement. At the same time, after the first handle moves from the second position to the first position, it can be unlocked through the first elastic mechanism without having to rotate the first handle again, thus simplifying the unlocking process.

[0008] In some embodiments, the first elastic mechanism includes a first unlocking push rod and a first unlocking spring. The first unlocking push rod is slidably disposed in the first lock housing and is drively connected to the first clutch pin. The two ends of the first unlocking spring abut against the first unlocking push rod and the first drive mechanism, respectively. In the first position and when the first lock cylinder is rotated, the first drive mechanism drives the first unlocking spring and the first unlocking push rod to move, thereby driving the first clutch pin to compress the first clutch spring and insert into the first clearance portion. In the second position and when the first lock cylinder is rotated, the first drive mechanism moves to compress the first unlocking spring.

[0009] Specifically, when the first lock cylinder is in the first position and rotated, the first drive mechanism drives the first unlocking spring and the first unlocking push rod to move, thereby driving the first clutch pin to compress the first clutch spring and insert it into the first clearance part; when the first lock cylinder is in the second position and rotated, the first clutch pin abuts against the part of the first clutch shaft that is not in the first clearance part, so that the first clutch pin and the first unlocking push rod are fixed relative to the first clutch shaft, and the first drive mechanism moves to compress the first unlocking spring and cause the first unlocking spring to store force; after the first handle moves from the second position to the first position, the first unlocking spring resets to drive the first unlocking push rod to drive the first clutch pin to compress the first clutch spring and insert it into the first clearance part.

[0010] In the above technical solution, by setting a first unlocking push rod and a first unlocking spring, the risk of damage to the first clutch pin and the first drive mechanism due to forced movement is reduced when the first handle is in the second position and the first lock cylinder is rotated. At the same time, after the first handle moves from the second position to the first position, the clutch module can automatically switch to the engaged state so that the door lock is in the unlocked state. The structure is simple and easy to implement.

[0011] In some embodiments, the first drive mechanism includes a first push rod and a first push rod spring, the first push rod being movably disposed within the first lock housing along a first direction. When the first lock cylinder is rotated in the first position, the first push rod moves to compress the first push rod spring.

[0012] In the above technical solution, by setting a first push rod spring, after the first lock cylinder is reset and the unlocking device is removed after unlocking is completed, the first push rod spring can extend to drive the first push rod to reset.

[0013] In some embodiments, the first lock cylinder includes a first lock shell and a first cam. The first lock shell is rotatably disposed within a first lock box, the first cam is mounted on one end of the first lock shell, and a first push rod abuts against the outer periphery of the first cam.

[0014] In the above technical solution, by setting a first cam so that the first lock housing can drive the first drive mechanism to move during rotation, the structure is simple and easy to implement.

[0015] In some embodiments, the first clutch module further includes a first handlebar torsion spring, which is sleeved on the outside of the first handlebar shaft and is used to provide an elastic force to the first handlebar shaft to drive the first handlebar shaft to move to a first position.

[0016] In the above technical solution, by setting a first handle torsion spring so that the first handle shaft is in the first position, the situation where the first clutch pin is not aligned with the first clearance part is prevented during emergency unlocking without any operation by the operator, thus simplifying the emergency unlocking process.

[0017] In some embodiments, the first motor unlocking module includes a first motor and a first motor push rod. The first motor push rod is movably disposed within a first lock box and is drively connected to a first elastic mechanism and a first clutch pin. The first motor drives the first motor push rod to move, and the first motor push rod pushes the first clutch pin to move, so that the first clutch pin inserts into a first clearance portion.

[0018] In the above technical solution, the first motor can drive the first motor push rod to push the first clutch pin to move, so that the first clutch pin connects the first handle shaft and the first clutch shaft. At the same time, the first drive mechanism and the first elastic mechanism can drive the first motor push rod to push the first clutch pin to move, so that the first drive mechanism and the first elastic mechanism can use part of the structure of the first motor unlocking module to unlock, which is beneficial to reduce the number of parts of the first panel assembly and reduce the size of the first panel assembly.

[0019] In some embodiments, the first motor unlocking module further includes a first motor slider and a first motor spring. The first motor slider is slidably disposed on the first motor push rod and is drively connected to the output end of the first motor. The two ends of the first motor spring abut against the first motor slider and the first motor push rod, respectively. When the first lock cylinder is rotated in the first position, the first drive mechanism drives the first elastic mechanism to move, thereby causing the first motor push rod to compress the first motor spring.

[0020] Specifically, during emergency unlocking, the first lock cylinder rotates the first drive mechanism and the first elastic mechanism, which in turn drive the first motor push rod to compress the first motor spring. This prevents the first motor slider from moving and thus prevents the first motor from rotating. After the first drive mechanism resets, the first motor push rod can reset under the elastic force of the first motor spring.

[0021] In the above technical solution, by setting a first motor slider and a first motor spring, the risk of damage to the first motor during emergency unlocking is reduced, and the structure is simple and easy to implement.

[0022] In some embodiments, the first motor push rod includes a body portion and an abutment portion. The body portion is along a first direction, and the end of the body portion away from the first handle shaft is used to abut against the first elastic mechanism. The abutment portion is disposed at the end of the body portion near the first handle shaft and extends circumferentially along the first handle shaft. The abutment portion is used to abut against the first clutch pin. The first direction is parallel to the length direction of the first lock box.

[0023] In the above technical solution, by setting the abutment part, when the first handle drives the first handle shaft and the first clutch shaft to move, the first clutch pin can continuously contact the abutment part, thereby preventing the first clutch pin from disengaging from the first clutch shaft when suddenly released during rotation, causing the clutch module to switch to the disengaged state, and the door lock to switch to the locked state, while causing the first clutch pin to interfere with the first motor push rod.

[0024] In some embodiments, the first motor unlocking module further includes a control circuit board and a micro switch. The control circuit board is electrically connected to the first motor, and the micro switch is electrically connected to the control circuit board. The micro switch is used to detect the position of the first handle shaft.

[0025] In the above technical solution, a micro switch is set to detect the position of the first handle shaft so that the operator can know the position of the first handle shaft, thereby making it easier for the operator to move the first handle shaft to the first position during emergency unlocking.

[0026] In some embodiments, the door lock further includes a second panel assembly, which includes a second lock housing and a transmission module disposed within the second lock housing. The transmission module includes a second handle, a second handle shaft, a second rotating shaft, and a second pin. The second handle is mounted on the second lock housing, the second handle shaft is connected to the second handle, the second rotating shaft is tractively connected to the latch assembly and has a second clearance portion corresponding to the second pin, and the second pin is mounted on the second handle shaft, with a portion of the second pin located within the second clearance portion. The first panel assembly is an outer door panel assembly, and the second panel assembly is an inner door panel assembly.

[0027] In the above technical solution, compared with the case where the second handle is connected to the latch assembly through an integral structure shaft, by connecting the second handle to the latch assembly through the second handle shaft and the second rotating shaft, and connecting the second handle shaft and the second rotating shaft through the second pin, the assembly tolerance between the latch assembly and the second handle can be allocated to the mating connection of the second handle, the second handle shaft, the second rotating shaft and the second pin, thereby facilitating the assembly of the door control lock.

[0038] The door lock 1000 will be described in detail below with reference to the attached diagram.

[0039] Please refer to Figures 1-5 , Figure 1 This is a schematic diagram of the structure of a door control lock 1000 provided in some embodiments of this application. Figure 2 This is an exploded view of the structure of a door lock 1000 provided in some embodiments of this application. Figure 3 This is an exploded view of the structure of the first panel assembly 100 provided in some embodiments of this application. Figure 4 This is an exploded view of the structure of the first clutch module 30 provided in some embodiments of this application. Figure 5 This is an exploded view of the structure of the first emergency unlocking module 40 provided in some embodiments of this application. Embodiments of this application provide a door control lock 1000, including a first panel assembly 100 and a bolt assembly 200. The first panel assembly 100 includes a first lock housing 10 and a first motor unlocking module 20, a first clutch module 30, and a first emergency unlocking module 40 disposed within the first lock housing 10. The first motor unlocking module 20 is used to unlock the access control system upon receiving an electric unlocking command. The first clutch module 30 includes a first handle 31, a first handle shaft 32, a first clutch pivot 33, a first clutch pin 34, and a first clutch spring 35. The first handle 31 is mounted on the first lock box 10. The first handle shaft 32 is connected to the first handle 31. The first clutch pin 34 is mounted on the first handle shaft 32. The first clutch pivot 33 is connected to the latch assembly 200 and has a first clearance portion 331 corresponding to the first clutch pin 34. The first handle shaft 32 has a first position that allows the first clutch pin 34 to insert into the first clearance portion 331 and a second position that causes the first clutch pin 34 to be misaligned with the first clearance portion 331. The first emergency unlocking module 40 includes a first lock cylinder 41, a first drive mechanism 42, and a first elastic mechanism 43. The first elastic mechanism 43 connects the first drive mechanism 42 and the first clutch pin 34. When the first lock cylinder 41 is rotated in the first position, the first drive mechanism 42 and the first elastic mechanism 43 drive the first clutch pin 34 to compress the first clutch spring 35 and insert it into the first clearance part 331, so that the door lock 1000 is in an emergency unlocking state; when the first lock cylinder 41 is rotated in the second position, the first drive mechanism 42 moves and the first elastic mechanism 43 stores force, so that when the first handle shaft 32 moves to the first position, it drives the first clutch pin 34 to insert into the first clearance part 331.

[0040] Please refer to Figure 1 and Figure 2The latch assembly 200 is a structural component disposed in an external structure (door frame or post 2000) for locking to another external structure (post 2000 or door frame). Exemplarily, the latch assembly 200 may include a lock body 210 and a square shaft 220. A latch 2101 is disposed on one side of the lock body 210. The latch 2101 extends out of the external structure where the latch assembly 200 is disposed and inserts into another external structure to lock the two external structures. The latch 2101 retracts into the external structure where the latch assembly 200 is disposed to unlock the two external structures. The square shaft 220 is drive-connected to the latch 2101. The square shaft 220 rotates to drive the latch 2101 to extend or retract into the external structure where the latch 2101 is disposed.

[0041] Please refer to Figure 2 In some embodiments, the door lock 1000 further includes a latch assembly 400, which is disposed on the side of the external structure where the latch assembly 200 is provided, for the latch 2101 to extend. The latch assembly 400 includes a latch plate 410, which has a latch 2101 opening for the latch 2101 to extend. A magnet 420 is disposed below the latch 2101 opening. The magnet 420 cooperates with a Hall element disposed on another external structure to detect the open and closed status of the door access control, and transmits the data to the backend through a circuit board electrically connected to the Hall element.

[0042] The first panel assembly 100 is an assembly structure integrating a first handle 31, a first lock cylinder 41 (or a key, password, or card reader module), as well as decorative and protective components. For example, the first panel assembly 100 includes a first lock box 10 and a first motor unlocking module 20, a first clutch module 30, and a first emergency unlocking module 40 disposed within the first lock box 10.

[0043] Please refer to Figure 3 The first lock box 10 is a housing structure for accommodating other structures of the first panel. In some embodiments, it includes a first housing 11 and a first cover plate 12. The first housing 11 has a first opening communicating with its interior on one side. The first cover plate 12 is detachably connected to the first housing 11 and is used to seal the first opening.

[0044] Please refer to Figure 3 and Figure 4The first clutch module 30 is a module in the first panel assembly 100 connected to the square shaft 220 of the latch assembly 200. It should be noted that the first clutch module 30 has a disengaged state and an engaged state. Taking the side where the first panel assembly 100 is located as an example, when the first clutch module 30 is engaged, the door lock 1000 is in the unlocked state. At this time, the operator can rotate the square shaft 220 through the first handle 31 to extend or retract the latch 2101 to open or close the access control. When the first clutch module 30 is disengaged and the access control is closed, the door lock 1000 is in the locked state. At this time, the operator rotating the first handle 31 will cause the first handle 31 to rotate freely, thereby driving the first handle shaft 32 to switch between the first position and the second position.

[0045] Please refer to Figure 4 The first handle 31 is a structural component that is partially exposed outside the first lock box 10 for the operator to rotate; the first handle shaft 32 is a structural component that is connected to the first handle 31 to transmit the rotation of the first handle 31; the first clutch shaft 33 is a shaft-shaped structure that is connected to the square shaft 220 in the first clutch module 30; and the first clutch pin 34 is a pin-shaped structural component that is set on the first handle shaft 32.

[0046] Please refer to Figure 4 In some embodiments, the first handlebar shaft 32 has a first mounting hole 32A extending through it along its axis. One end of the first clutch shaft 33 is located within the first mounting hole 32A. A first mounting groove 32B is provided on the wall of the first mounting hole 32A, extending radially through the first handlebar shaft 32. The first clutch pin 34 is accommodated within the first mounting groove 32B. A first clearance portion 331 is provided on the circumferential side of the first clutch shaft 33. Exemplarily, the first clearance portion 331 can be a groove or a blind hole. When the first handlebar shaft 32 is in the first position, one end of the first mounting groove 32B is aligned with the first clearance portion 331. At this time, under the action of external force, one end of the first clutch pin 34 protrudes from the wall of the first mounting hole 32A and is inserted into the first clearance part 331 to connect the first clutch shaft 33 and the first handle shaft 32; or, at this time, under the action of external force, the first clutch pin 34 disengages from the first mounting hole 32A so that the first clutch shaft 33 and the first handle shaft 32 can rotate independently.

[0047] Please refer to Figure 4 In some embodiments, the width of the end of the first mounting groove 32B near the first mounting hole 32A is smaller than the width of the end of the first mounting groove 32B near the outer peripheral surface of the first handle shaft 32, so as to form a first stepped surface on the groove wall of the first mounting groove 32B. The first clutch spring 35 is sleeved outside the first clutch pin 34 and located inside the first mounting groove 32B. The two ends of the first clutch spring 35 abut against the first stepped surface and the first clutch pin 34, respectively.

[0048] Please refer to Figure 4 In some embodiments, the first handlebar shaft 32 includes a first handlebar shaft body 321 and a first clutch cover plate 322. The first handlebar shaft body 321 and the first clutch cover plate 322 are overlapped and detachably connected along the axis of the first handlebar shaft 32. The first mounting hole 32A passes through the first handlebar shaft body 321 and the first clutch cover plate 322 in sequence. The first mounting groove 32B is located on the side of the first handlebar shaft body 321 facing the first clutch cover plate 322.

[0049] Please refer to Figure 3 The first motor unlocking module 20 can be a module that drives the first clutch pin 34 to connect the first handle shaft 32 and the first clutch shaft 33, or the first motor unlocking module 20 can also be a module that directly connects the first handle shaft 32 and the first clutch shaft 33.

[0050] In some embodiments, the first motor unlocking module 20 includes a first motor status board 26, which is electrically connected to the driving component in the first motor unlocking module 20. The first motor status board 26 is used to read the driving component in the first motor unlocking module 20 and upload it to the background.

[0051] For example, the door lock 1000 is electrically connected to the access control controller and can work with the access control controller's card swiping, password, and facial recognition functions to control personnel access. Specifically, the door lock 1000 can authorize access via local card swiping, password, and facial recognition, or remotely authorize unlocking, driving the first motor unlocking module 20 to the unlocked state to achieve unlocking.

[0052] In some embodiments, the driving component in the first motor unlocking module 20 may be a solenoid.

[0053] The first emergency unlocking module 40 is a structural module used for emergency unlocking of the access control system.

[0054] The first lock cylinder 41 can be a mechanical lock cylinder or a computer key lock cylinder. For example, the first lock cylinder 41 includes a first wireless chip 413 partially located outside the first lock box 10. Specifically, in an emergency unlocking operation using the computer key, the computer key obtains ID information through the first wireless chip 413, confirms the lock's access rights, and then issues authorization to the computer key to perform the emergency unlocking. In a mechanical emergency unlocking operation, the emergency unlocking operation can be achieved by inserting and turning a specific mechanical key.

[0055] The first drive mechanism 42 and the first elastic mechanism 43 are mechanisms in the first emergency unlocking module 40 that follow the rotation of the first lock cylinder 41 to push the first clutch pin 34 to compress the first clutch spring 35 and insert it into the first clearance part 331, thereby connecting the first clutch shaft 33 and the first handle shaft 32. Exemplarily, the first drive mechanism 42 can be a transmission rod, and the first elastic mechanism 43 can be a spring. The transmission rod is slidably installed inside the first lock box 10, with one end abutting against the outer periphery of the first lock cylinder 41, and one end of the spring connected to the other end of the transmission rod. The other end of the spring can abut against the end of the first clutch pin 34 away from the first clutch shaft 33.

[0056] In some embodiments, the first emergency unlocking module 40 includes a first bracket and a first bracket cover. The first bracket has a second opening on the side facing the first bracket cover. The first bracket cover is installed on the first bracket and blocks the second opening. A space is formed between the first bracket and the first bracket cover to accommodate a portion of the first driving mechanism 42 and a portion of the first elastic mechanism 43.

[0057] Specifically, when the first handle shaft 32 is in the first position, the first clutch pin 34 is aligned with the first clearance part 331. At this time, the first lock cylinder 41 is rotated, so that the first lock cylinder 41 can drive the first drive mechanism 42 and the first elastic mechanism 43 to drive the first clutch pin 34 to compress the first clutch spring 35 and insert it into the first clearance part 331. This allows the first handle 31 to be connected to the lock tongue assembly 200 through the first handle shaft 32 and the first clutch rotating shaft 33, so that the door lock 1000 is in an emergency unlocking state. When the first handle shaft 32 is in the second position, the first clutch pin 34 is misaligned with the first clearance part 331. At this time, rotating the first lock cylinder 41 causes the first lock cylinder 41 to tend to drive the first drive mechanism 42 and the first elastic mechanism 43 to drive the first clutch pin 34 to move. However, since the first clutch pin 34 is not aligned with the first clearance part 331, the first clutch pin 34 will interfere with the first clutch shaft 33 during the movement. At this time, the first elastic mechanism 43 is compressed to store force, reducing the risk of damage to the first clutch pin 34, the first drive mechanism 42 and the first elastic mechanism 43 due to forced movement. Then, rotating the first handle 31 again causes the first handle shaft 32 to rotate from the second position to the first position. The first elastic mechanism 43 can drive the first clutch pin 34 to insert into the first clearance part 331, thereby enabling the first handle 31 to be connected to the lock tongue assembly 200 through the first handle shaft 32 and the first clutch shaft 33, so that the door lock 1000 is in an emergency unlocking state.

[0058] Understandably, after the first clutch pin 34 is inserted into the first clearance part 331, when the first handle 31 is rotated to drive the first handle shaft 32 and the first clutch shaft 33 to move, the first handle shaft 32 and the first clutch shaft 33 will provide shearing force to the first clutch shaft 33 to generate friction, thereby restricting the first clutch pin 34 from disengaging from the first clutch shaft 33 under the drive of the first clutch spring 35.

[0059] In this embodiment, by setting a first elastic mechanism 43, when the first handle 31 is in the second position and the first lock cylinder 41 is rotated, the first elastic mechanism 43 can store force, thereby reducing the risk of damage to the first clutch pin 34 and the first drive mechanism 42 due to forced movement. At the same time, after the first handle 31 moves from the second position to the first position, it can be unlocked through the first elastic mechanism 43 without having to rotate the first handle 31 again, thus simplifying the unlocking process.

[0060] Please refer to Figures 5-10 , Figure 6 for Figure 5 A magnified view of a portion of point A in the middle. Figure 7 This is a schematic diagram of the structure of the first panel assembly 100 when it is in the first position and the first lock cylinder 41 is rotated, provided in some embodiments of this application. Figure 8 for Figure 7 A magnified view of a section at point B. Figure 9 This is a schematic diagram of the structure of the first panel assembly 100 when it is in the second position and the first lock cylinder 41 is rotated, provided in some embodiments of this application. Figure 10 for Figure 9 A partial enlarged view at point C. According to some embodiments of this application, the first elastic mechanism 43 includes a first unlocking push rod 431 and a first unlocking spring 432. The first unlocking push rod 431 is slidably disposed in the first lock box 10 and is connected to the first clutch pin 34. The two ends of the first unlocking spring 432 abut against the first unlocking push rod 431 and the first drive mechanism 42, respectively. In the first position and when the first lock cylinder 41 is rotated, the first drive mechanism 42 drives the first unlocking spring 432 and the first unlocking push rod 431 to move, so as to drive the first clutch pin 34 to compress the first clutch spring 35 and insert it into the first clearance part 331; in the second position and when the first lock cylinder 41 is rotated, the first drive mechanism 42 moves to compress the first unlocking spring 432.

[0061] The first unlocking push rod 431 is a rod-shaped structure that is movable in the first lock box 10 along the first direction X, which can be parallel to the length direction of the first lock box 10.

[0062] In some embodiments, the first bracket is provided with a first slide groove extending along the first direction X, and the first unlocking push rod 431 is slidably disposed in the first slide groove along the first direction X.

[0063] Understandably, the preload applied to the first unlocking spring 432 should be greater than the elastic force generated by the first clutch spring 35 when the first clutch pin 34 is inserted into the first clearance portion 331.

[0064] In some embodiments, the elastic coefficient of the first unlocking spring 432 may be greater than the elastic coefficient of the first clutch spring 35. For example, the diameter of the spring wire of the first unlocking spring 432 is greater than the diameter of the spring wire of the first clutch spring 35, and the mean diameter of the first unlocking spring 432 is greater than the mean diameter of the first clutch spring 35.

[0065] Specifically, when the first lock cylinder 41 is rotated in the first position, the first drive mechanism 42 drives the first unlocking spring 432 and the first unlocking push rod 431 to move, thereby driving the first clutch pin 34 to compress the first clutch spring 35 and insert it into the first clearance part 331; when the first lock cylinder 41 is rotated in the second position, the first clutch pin 34 abuts against the part of the first clutch shaft 33 that is not in the first clearance part 331, so that the first clutch pin 34 and the first unlocking push rod 431 are fixed relative to the first clutch shaft 33, and the first drive mechanism 42 moves to compress the first unlocking spring 432, and causes the first unlocking spring 432 to store force; after the first handle 31 moves from the second position to the first position, the first unlocking spring 432 resets to drive the first unlocking push rod 431 to drive the first clutch pin 34 to compress the first clutch spring 35 and insert it into the first clearance part 331.

[0066] In this embodiment, by setting a first unlocking push rod 431 and a first unlocking spring 432, the risk of damage to the first clutch pin 34 and the first drive mechanism 42 due to forced movement is reduced when the first handle 31 is in the second position and the first lock cylinder 41 is rotated. At the same time, after the first handle 31 moves from the second position to the first position, the clutch module can automatically switch to the engaged state so that the door lock 1000 is in the unlocked state. The structure is simple and easy to implement.

[0067] Please refer to Figures 5-10 According to some embodiments of this application, the first drive mechanism 42 includes a first push rod 421 and a first push rod spring 422. The first push rod 421 is movably disposed within the first lock box 10 along a first direction X. When in the first position and the first lock cylinder 41 is rotated, the first push rod 421 moves to compress the first push rod spring 422.

[0068] The first push rod 421 is a rod-shaped structure that extends integrally along the first direction X within the first lock box 10.

[0069] In some embodiments, please refer to Figure 5The first push rod 421 is bent and includes a first part and a second part. The first part extends along a third direction Z, and the second part extends along a first direction X. One end of the first push rod spring 422 is connected to or abuts against the first part, and the other end of the first push rod spring 422 is connected to or abuts against the first bracket or the first lock box 10. The first bracket is provided with a limiting groove extending along the first direction X. The second part of the first push rod 421 is located in the limiting groove and is adapted to the limiting groove.

[0070] In some embodiments, please refer to Figure 5 and Figure 6 A first oblong hole 4211 is provided on the portion of the first push rod 421 extending along the first direction X. The first oblong hole 4211 extends along the first direction X. A first protrusion 4212 is provided on the groove wall of the first oblong hole 4211 near the first lock cylinder 41. The first unlocking spring 432 is located inside the first oblong hole 4211, and one end of the first unlocking spring 432 is sleeved outside the first protrusion 4212. A second protrusion 4311 is provided on the side of the first unlocking push rod 431 facing the first push rod 421 in the third direction Z. The second protrusion 4311 is slidably provided in the first oblong hole 4211 along the first direction X and abuts against the other end of the first unlocking spring 432. In this way, the first drive mechanism 42 and the first elastic mechanism 43 share the length space of the first lock box 10 in the first direction X, which helps to reduce the length space of the lock box.

[0071] In this embodiment, by providing a first push rod spring 422, after the first lock cylinder 41 is reset and the unlocking device is removed after unlocking is completed, the first push rod spring 422 can extend to drive the first push rod 421 to reset.

[0072] Please refer to Figures 5-10 According to some embodiments of this application, the first lock cylinder 41 includes a first lock shell 411 and a first cam 412. The first lock shell 411 is rotatably disposed in the first lock box 10, the first cam 412 is installed at one end of the first lock shell 411, and the first push rod 421 abuts against the outer periphery of the first cam 412.

[0073] Specifically, the first cam 412 has a first end away from the axis of the first lock housing 411 and a second end close to the axis of the first lock housing 411. When the second end of the first cam 412 abuts against the first push rod 421, the first drive mechanism 42 and the first elastic mechanism 43 are located away from the first clutch pin 34. At this time, the first drive mechanism 42 and the first elastic mechanism 43 do not apply external force to the first clutch pin 34, and the first clutch pin 34 disengages from the first clearance portion 331 under the elastic force of the first clutch spring 35. The first cam 412 rotates under the drive of the first lock housing 411, so that the area of ​​the first cam 412 abutting against the first push rod 421 moves closer to the first end, thereby driving the first push rod 421 to compress the first push rod spring 422 and move towards the first clutch pin 34. At this time, if the first handle shaft 32 is in the first position, please refer to... Figure 7 and Figure 8 The first push rod 421 can drive the first unlocking push rod 431 and the first unlocking spring 432 to drive the first clutch pin 34 to compress the first clutch spring 35 so that it can be inserted into the first clearance part 331, thereby putting the door lock 1000 into the emergency unlocking state. At this time, if the first handle shaft 32 is in the second position, please refer to... Figure 9 and Figure 10 The first clutch pin 34 abuts against the outer peripheral surface of the non-first clearance portion 331 of the first clutch shaft 33, compressing the first unlocking spring 432 and preventing the first unlocking push rod 431 and the first clutch pin 34 from moving. After the first handle shaft 32 switches from the second position to the first position, the first unlocking spring 432 extends, driving the first unlocking push rod 431 to compress the first clutch spring 35, which then inserts into the first clearance portion 331, thus putting the door lock 1000 into an emergency unlocking state. After unlocking, the first lock housing 411 drives the first cam 412 to rotate, causing the area where the first cam 412 abuts against the first push rod 421 to move closer to the second end. At this time, the first push rod spring 422 extends, causing the first push rod 421, the first unlocking push rod 431, and the first unlocking spring 432 to reset.

[0074] In this embodiment, the first cam 412 is provided so that the first lock housing 411 can drive the first drive mechanism 42 to move during rotation, which is simple in structure and easy to implement.

[0075] Please refer to Figure 4 , Figure 7 and Figure 9 According to some embodiments of this application, the first clutch module 30 further includes a first handle torsion spring 36, which is sleeved on the outside of the first handle shaft 32 and is used to provide elastic force to the first handle shaft 32 to drive the first handle shaft 32 to move to the first position.

[0076] In some embodiments, please refer to Figure 4 The first handle torsion spring 36 is located on the side of the first handle shaft 32 facing the first handle 31. A fourth protrusion 3221 is provided on the side of the first clutch cover 322 facing the first handle shaft body 321. The end face of the fourth protrusion 3221 protrudes from the side of the first handle shaft body 321 away from the first clutch cover 322. One end of the first handle torsion spring 36 is connected to the first lock box 10, and the other end of the first handle torsion spring 36 abuts against the side of the protrusion. When the first handle 31 drives the first handle shaft 32 to move from the first position to the second position, the first handle torsion spring 36 is compressed. The first handle torsion spring 36 elastically returns to its original position to drive the first handle shaft 32 to move from the second position to the first position.

[0077] In this embodiment, by setting a first handle torsion spring 36 so that the first handle shaft 32 is in the first position, the situation where the first clutch pin 34 is not aligned with the first clearance part 331 is prevented during emergency unlocking without any operation by the operator, thus simplifying the emergency unlocking process.

[0078] Please refer to Figure 11 , Figure 11 This is an exploded view of the structure of a first motor unlocking module 20 provided in some embodiments of this application. According to some embodiments of this application, the first motor unlocking module 20 includes a first motor 21 and a first motor push rod 22. The first motor push rod 22 is movably disposed within a first lock box 10, and is drively connected to a first elastic mechanism 43 and a first clutch pin 34. The first motor 21 drives the first motor push rod 22 to move, and the first motor push rod 22 pushes the first clutch pin 34 to move, so that the first clutch pin 34 inserts into a first clearance portion 331.

[0079] The first motor 21 is a driving component in the first motor unlocking module 20 used to drive the first motor push rod 22. Understandably, the first motor 21 can also be other driving components, such as a solenoid.

[0080] The first motor push rod 22 can be a rod-shaped structure that extends as a whole along the first direction X.

[0081] In some embodiments, please refer to Figure 11 The first motor unlocking module 20 also includes a first motor bracket 25 and a first motor bracket cover 251. The first motor bracket 25 is used to accommodate at least a portion of the first motor 21 and the first motor push rod 22. The first motor bracket 25 and the first motor bracket cover 251 are stacked in a third direction Z and are detachably connected. The side of the first motor bracket 25 facing the first motor bracket cover 251 has an opening communicating with its interior, and the first motor bracket cover 251 is used to seal the opening.

[0082] In this embodiment, the first motor 21 can drive the first motor push rod 22 to push the first clutch pin 34 to move, so that the first clutch pin 34 connects the first handle shaft 32 and the first clutch shaft 33. At the same time, the first drive mechanism 42 and the first elastic mechanism 43 can drive the first motor push rod 22 to push the first clutch pin 34 to move, so that the first drive mechanism 42 and the first elastic mechanism 43 can use part of the structure of the first motor unlocking module 20 for unlocking, which helps to reduce the number of parts of the first panel assembly 100 and reduce the size of the first panel assembly 100.

[0083] Please refer to Figure 11 According to some embodiments of this application, the first motor unlocking module 20 further includes a first motor slider 23 and a first motor spring 24. The first motor slider 23 is slidably disposed on the first motor push rod 22 and is connected to the output end of the first motor 21. The two ends of the first motor spring 24 abut against the first motor slider 23 and the first motor push rod 22, respectively. When the first lock cylinder 41 is rotated in the first position, the first drive mechanism 42 drives the first elastic mechanism 43 to move, thereby causing the first motor push rod 22 to compress the first motor spring 24.

[0084] The first motor slider 23 is a block structure that is connected to the first motor 21 and slidably mounted on the first motor push rod 22.

[0085] Specifically, during emergency unlocking, the first lock cylinder 41 rotates the first drive mechanism 42 and the first elastic mechanism 43, which in turn drive the first motor push rod 22 to compress the first motor spring 24. This prevents the first motor slider 23 from moving and thus prevents the first motor 21 from rotating. After the first drive mechanism 42 is reset, the first motor push rod 22 can be reset under the elastic force of the first motor spring 24.

[0086] In this embodiment, by setting the first motor slider 23 and the first motor spring 24, the risk of damage to the first motor 21 during emergency unlocking is reduced, and the structure is simple and easy to implement.

[0087] Please refer to Figure 7 , Figure 9 and Figure 11 According to some embodiments of this application, the first motor push rod 22 includes a body portion 221 and an abutment portion 222. The body portion 221 extends along a first direction X. The end of the body portion 221 away from the first handle shaft 32 is used to abut against the first elastic mechanism 43. The abutment portion 222 is disposed at the end of the body portion 221 near the first handle shaft 32 and extends along the circumference of the first handle shaft 32. The abutment portion 222 is used to abut against the first clutch pin 34.

[0088] In some embodiments, please refer to Figure 7 , Figure 9 and Figure 11 The first motor push rod 22 includes a body portion 221 and an abutment portion 222. The body portion 221 extends radially along the first handle shaft 32, and the center point of the first handle 31 is located on the extension line of the body portion 221. The end of the body portion 221 away from the first handle shaft 32 is used to abut against the first drive mechanism 42. The abutment portion 222 is disposed at the end of the body portion 221 near the first handle shaft 32 and extends circumferentially along the first handle shaft 32. The abutment portion 222 is used to abut against the first clutch pin 34. This ensures that when the first handle 31 drives the first handle shaft 32 and the first clutch shaft 33, the first clutch pin 34 can continuously abut against the abutment portion 222, thereby preventing the first clutch pin 34 from disengaging from the first clutch shaft 33 due to sudden release during rotation, which would cause interference between the first clutch pin 34 and the first motor push rod 22.

[0089] In some embodiments, please refer to Figure 11 The first motor 21 is located on one side of the body portion 221 in the second direction Y. A second mounting groove 221A is provided on the side of the body portion 221 facing the first motor 21, extending along the first direction X. The first motor slider 23 is slidably disposed within the second mounting groove 221A. A first motor spring 24 is located within the second mounting groove 221A, with both ends of the first motor spring 24 abutting against the groove wall of the second mounting groove 221A and the first motor slider 23, respectively. The first motor spring 24 and the first motor slider 23 are arranged sequentially along the direction of the first drive mechanism 42 pointing towards the first motor push rod 22. A second oblong hole 23A is provided on the side of the first motor slider 23 facing the first motor 21, extending along the third direction Z. A connecting sleeve 211 is provided at the drive end of the first motor 21, and a third protrusion 211A is provided on the side of the connecting sleeve 211 facing the first motor slider 23, inserted into the second oblong hole 23A. The third protrusion 211A is offset from the output end of the first motor 21.

[0090] In this embodiment, by setting the abutment part 222, when the first handle 31 drives the first handle shaft 32 and the first clutch shaft 33 to move, the first clutch pin 34 can continuously contact the abutment part 222, thereby preventing the first clutch pin 34 from disengaging from the first clutch shaft 33 during rotation, causing the clutch module to switch to the disengaged state, and causing the door lock 1000 to switch to the locked state. At the same time, it causes the first clutch pin 34 to interfere with the first motor push rod 22.

[0091] Please refer to Figure 4 , Figure 7 and Figure 9According to some embodiments of this application, the first motor unlocking module 20 further includes a control circuit board 51 and a micro switch 50. The control circuit board 51 is electrically connected to the first motor 21, and the micro switch 50 is electrically connected to the control circuit board 51. The micro switch 50 is used to detect the position of the first handle shaft 32.

[0092] A micro switch 50 is a specific type of electrical switch. When an external force (such as pressing or displacement) is applied to the switch to a certain extent through a mechanical lever or other mechanism, the micro switch 50 can quickly trigger the switch to open or close, thereby sending a signal to the control circuit.

[0093] In some embodiments, please refer to Figure 4 The micro switch 50 is located on the outer periphery of the first handle shaft 32. The fifth protrusion 3222 is provided on the periphery of the first clutch cover plate 322. When the first handle shaft 32 is in the first position, the fifth protrusion 3222 abuts against the trigger switch of the micro switch 50. When the first handle shaft 32 is in the second position, the fifth protrusion 3222 disengages from the trigger switch of the micro switch 50.

[0094] In this embodiment, a micro switch 50 is set to detect the position of the first handle shaft 32 so that the operator can know the position of the first handle shaft 32, thereby making it easier for the operator to move the first handle shaft 32 to the first position during emergency unlocking.

[0095] Please refer to Figure 12 and Figure 13 , Figure 12 This is a structural cross-sectional view of the second panel assembly 300 provided in some embodiments of this application. Figure 13 This is an exploded view of the transmission module 320 provided in some embodiments of this application. According to some embodiments of this application, the door lock 1000 further includes a second panel assembly 300, which includes a second lock housing 310 and a transmission module 320 disposed within the second lock housing 310. The transmission module 320 includes a second handle 3201, a second handle shaft 3202, a second rotating shaft 3203, and a second pin 3204. The second handle 3201 is mounted on the second lock housing 310, the second handle shaft 3202 is connected to the second handle 3201, the second rotating shaft 3203 is pulsatorically connected to the latch assembly 200 and has a second clearance portion 32031 corresponding to the second pin 3204, the second pin 3204 is mounted on the second handle shaft 3202, and a portion of the second pin 3204 is located within the second clearance portion 32031. The first panel assembly 100 is an outer door panel assembly, and the second panel assembly 300 is an inner door panel assembly.

[0096] Please refer to Figure 13The second handle shaft 3202 has a second mounting hole extending through it along its axis. One end of the second rotating shaft 3203 is located within the second mounting hole. A third mounting groove 3202C is provided on the wall of the second mounting hole, extending radially through the second handle shaft 3202. A second pin 3204 is accommodated within the third mounting groove 3202C. A second clearance portion 32031 is provided on the circumferential side of the second rotating shaft 3203. Exemplarily, the second clearance portion 32031 can be a groove or a blind hole. One end of the third mounting groove 3202C is aligned with the second clearance portion 32031. One end of the second pin 3204 protrudes from the wall of the second mounting hole and is inserted into the second clearance portion 32031 to connect the second rotating shaft 3203 and the second handle shaft 3202.

[0097] In some embodiments, please refer to Figure 13 The width of the end of the third mounting groove 3202C near the second mounting hole is greater than the width of the end of the third mounting groove 3202C near the outer peripheral surface of the second handle shaft 3202, so as to form a second stepped surface on the groove wall of the third mounting groove 3202C. The end of the second pin 3204 away from the second rotating shaft 3203 abuts against the second stepped surface to restrict the second pin 3204 from disengaging from the end of the third mounting groove 3202C near the outer peripheral surface of the second handle shaft 3202.

[0098] In some embodiments, please refer to Figure 13 The second handlebar shaft 3202 includes a second handlebar shaft 3202 body and a second clutch cover plate. The second handlebar shaft 3202 body and the second clutch cover plate are overlapped and detachably connected along the axis of the second handlebar shaft 3202. The second mounting hole includes a first hole section 3202A penetrating through the second clutch cover plate and a second hole section 3202B penetrating through the second handlebar shaft 3202 body. A sixth protrusion 32032 is provided on the outer periphery of the portion of the second rotating shaft 3203 inserted into the second mounting hole. A first groove adapted to the sixth protrusion 32032 is provided on the hole wall of the first hole section 3202A. A second groove is provided on the hole wall of the second hole section 3202B. The second groove extends circumferentially along the second hole section 3202B. When viewed along the axial direction of the second mounting hole, a part of the second groove overlaps with the first groove, and another part of the second groove does not overlap with the first groove.

[0099] Specifically, after inserting the second rotating shaft 3203 into the second mounting hole and positioning the sixth protrusion 32032 within the second groove, the second rotating shaft 3203 can be rotated to align the second clearance portion 32031 with the third mounting groove 3202C and to displace the sixth protrusion 32032 from the first groove. This allows the second rotating shaft 3203 to be fixed relative to the second handle shaft 3202 after the second pin 3204 is inserted into the second clearance portion 32031.

[0100] In this embodiment, compared to the case where the second handle 3201 is connected to the latch assembly 200 via an integral shaft, by connecting the second handle 3201 to the latch assembly 200 via the second handle shaft 3202 and the second rotating shaft 3203, and by connecting the second handle shaft 3202 and the second rotating shaft 3203 via the second pin 3204, the assembly tolerance between the latch assembly 200 and the second handle 3201 can be allocated to the mating connection of the second handle 3201, the second handle shaft 3202, the second rotating shaft 3203 and the second pin 3204, thereby facilitating the assembly of the door lock 1000.

[0101] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
