Description

Technical Field

[0001] This application relates to the field of electronic locks, and more specifically, to an emergency unlocking module and a smart door lock. Background Technology

[0002] Smart door locks typically include a lock body embedded in the door and a main control unlocking / locking mechanism and an emergency unlocking / locking mechanism installed on the door. The main control unlocking / locking mechanism is used for the regular unlocking / locking of the smart door lock, while the emergency unlocking / locking mechanism is used for emergency unlocking / locking of the smart door lock. To facilitate emergency unlocking for users, existing smart door locks are equipped with a Type-C male connector, which connects to the data interface of a mobile phone to collect the phone's identity information and obtain the power required for the locking module to operate.

[0003] However, the Type-C male connector needs to protrude from the surface of the lock body when connecting to a mobile phone, so it is less concealed and more prone to damage compared to the Type-C female connector. Utility Model Content

[0004] This application provides an emergency unlocking module and a smart door lock. When emergency unlocking is needed, it facilitates the user to connect the Type-C male connector to the mobile phone's data interface. When emergency unlocking is not required, it improves the concealment of the Type-C male connector and reduces the risk of damage to the Type-C male connector.

[0005] In a first aspect, embodiments of this application provide an emergency unlocking module, including a bracket, a first elastic element, an electronic lock cylinder, a lock cylinder sleeve, a rotating shaft, and a locking mechanism. The lock cylinder sleeve is fitted over the electronic lock cylinder and movably disposed within the bracket along a first direction parallel to the axis of the lock cylinder sleeve. The electronic lock cylinder includes a Type-C male connector and a motor. The Type-C male connector is electrically connected to the motor and extends out of the lock cylinder sleeve. The rotating shaft drivesly connects the output shaft of the motor and an external structural component. The lock cylinder sleeve has a locked position and an unlocked position. In the locked position, at least a portion of the Type-C male connector is located within the bracket. In the unlocked position, the Type-C male connector extends out of the bracket. The first elastic element is used to drive the lock cylinder sleeve to move towards the unlocked position. The locking mechanism is disposed within the bracket and is used to releasably lock the lock cylinder sleeve when it is in the locked and unlocked positions.

[0006] Specifically, in case of emergency unlocking, the locking mechanism releases the lock cylinder sleeve from the locked position, allowing it to move towards the unlocked position under the action of the first elastic element, thus extending the Type-C male connector from the bracket. The locking mechanism then locks the lock cylinder sleeve in the unlocked position, preventing the first elastic element from compressing and causing the lock cylinder sleeve to move towards the locked position when the user connects the Type-C male connector to the phone's data interface.

[0007] When emergency unlocking is not required, the locking mechanism releases the lock cylinder sleeve from the unlocked position. Then, pressing the Type-C male connector compresses the first elastic element, causing the lock cylinder sleeve to move towards the locked position, positioning the Type-C male connector within the bracket. The locking mechanism then locks the lock cylinder sleeve in the locked position, preventing it from extending out of the bracket under the action of the first elastic element.

[0008] In the above technical solution, during emergency unlocking, the Type-C male connector extends from the bracket, and the locking mechanism releasably locks the lock cylinder sleeve in the unlocked position, facilitating the user's connection between the Type-C male connector and the mobile phone's data interface, thus enabling emergency unlocking. During normal use, the Type-C male connector is located within the bracket, and the locking mechanism releasably locks the lock cylinder sleeve in the closed position, reducing the risk of damage to the Type-C male connector from external impacts and facilitating its concealment.

[0009] In some embodiments, the locking mechanism includes a limiting pin, a second elastic member, and a limiting assembly. The limiting pin is movably disposed within the bracket along a second direction. The lock cylinder sleeve is provided with a first limiting groove and a second limiting groove. The limiting pin is inserted into the first limiting groove to lock the lock cylinder sleeve in a locked position, and the limiting pin is inserted into the second limiting groove to lock the lock cylinder sleeve in an unlocked position. The second direction is perpendicular to the first direction. The second elastic member is used to drive the limiting pin to insert into the first limiting groove or the second limiting groove. The limiting assembly is used to releasably lock the limiting pin when it is inserted into the first limiting groove or the second limiting groove.

[0010] In the above technical solution, by setting a second elastic element, when the limiting pin is aligned with the first limiting groove or the second limiting groove, the limiting pin can be inserted into the first limiting groove or the second limiting groove under the action of the second elastic element, thereby facilitating the locking of the limiting component on the limiting pin, and thus facilitating the locking of the lock cylinder in the locked position and the unlocked position. The structure is simple and easy to implement.

[0011] In some embodiments, the first limiting groove has a first guide surface and a second guide surface disposed opposite to each other in a first direction, and the second limiting groove has a third guide surface and a fourth guide surface disposed opposite to each other in a first direction; along the axis away from the lock cylinder sleeve pointing towards the limiting pin, the distance between the first guide surface and the second guide surface gradually increases in the first direction, and the distance between the third guide surface and the fourth guide surface gradually increases in the first direction.

[0012] In the above technical solution, by setting a first guide surface and a second guide surface, and setting a third guide surface and a fourth guide surface, when the limiting component releases the limiting pin and the lock cylinder sleeve switches between the unlocked position and the locked position under the action of external force (the elastic force of the first elastic element or the user's pressing force), the first guide surface and the second guide surface can guide the limiting pin to squeeze the second elastic element to disengage from the first limiting groove, and the third guide surface and the fourth guide surface can guide the limiting pin to squeeze the second elastic element to disengage from the second limiting groove, thereby reducing the risk of the limiting pin getting stuck in the first or second limiting groove and improving the smoothness of the lock cylinder sleeve switching between the unlocked position and the locked position.

[0013] In some embodiments, the limiting component includes a button movably disposed within a bracket along a first direction. The button includes a limiting portion and a clearance portion arranged along the first direction. The button has a first position and a second position. In the first position, the limiting portion abuts against a limiting pin along the second direction to restrict the limiting pin from disengaging from the first limiting groove or the second limiting groove. In the second position, the clearance portion allows the limiting pin to disengage from the first limiting groove or the second limiting groove.

[0014] In the above technical solution, by setting a limiting part and a clearance part on the button, the operator can adjust the position of the button by applying external force to the button, so as to adjust the locking and releasing of the limiting pin. The structure is simple and easy to implement.

[0015] In some embodiments, the limiting component further includes a third elastic element disposed within the bracket and used to drive the button to move to the first position.

[0016] In the above technical solution, by setting a third elastic element, the button can move to the position of the locking limit pin when the user does not apply external force to the button. Then, when the second elastic element drives the limit pin to insert into the first limit groove or the second limit groove, the limiting part of the button can lock the limit pin. The structure is simple and easy to implement.

[0017] In some embodiments, the button further includes a pressing portion and a connecting portion. The pressing portion, connecting portion, clearance portion and limiting portion are arranged sequentially along a first direction. The pressing portion is located outside the bracket, and the connecting portion protrudes from the clearance portion to form a first stepped surface on the outer surface of the button. The projection of the first stepped surface along the first direction at least partially overlaps with the projection of the limiting pin.

[0018] In the above technical solution, the orthographic projection of the first step surface and the orthographic projection of the limiting pin overlap at least partially along the first direction, so that when the user presses the button to compress the third elastic element and causes the button to move to the second position, the first step surface can abut against the limiting pin, thereby preventing the risk of the button excessively moving along the first direction and crushing the third elastic element.

[0019] In some embodiments, the bracket is provided with a first receiving hole on one side in a first direction, and the lock cylinder sleeve is movably disposed in the first receiving hole; in the locked position, the Type-C male connector is located in the first receiving hole; in the unlocked position, the Type-C male connector extends out of the first receiving hole; the emergency unlocking module also includes an outer cover, which is installed on the outer surface of the bracket and has a first through hole corresponding to the first receiving hole, the diameter of the first through hole being smaller than the diameter of the lock cylinder sleeve.

[0020] In the above technical solution, by setting the diameter of the first through hole to be smaller than the diameter of the lock cylinder sleeve, the outer cover can abut against the lock cylinder sleeve when the first elastic element drives the lock cylinder sleeve to move to the unlock position, thereby preventing the lock cylinder sleeve from disengaging from the first receiving hole of the lock body.

[0021] In some embodiments, the emergency unlocking module further includes a rubber stopper having a closed position for closing the first through hole and an open position for opening the first through hole.

[0022] In the above technical solution, by setting the rubber plug to a closed position with a closed first through hole, the risk of external dust falling on the Type-C male connector can be reduced, and the concealment of the Type-C male connector can be improved; by setting the rubber plug to an open position with an open first through hole, the risk of the rubber plug interfering with the connection between external devices and the Type-C male connector can be reduced.

[0023] In some embodiments, the bracket is provided with a second receiving hole on one side in the second direction, the second receiving hole is connected to the first receiving hole, at least a portion of the locking mechanism is received in the second receiving hole, the first direction is perpendicular to the second direction; the outer cover includes a first part and a second part, the first through hole is located in the first part, the second part is bent relative to the first part and extends along the first direction, and blocks the second receiving hole.

[0024] In the above technical solution, a second receiving hole is provided to facilitate the installation of the locking mechanism. At the same time, the second part of the outer cover blocks the second receiving hole to isolate the locking mechanism from the external structure, which helps to improve the stability of the locking mechanism's operation. The structure is simple and easy to implement.

[0025] Secondly, embodiments of this application provide an intelligent door lock, including a lock body, a bolt, and an emergency unlocking module as provided in any embodiment of the first aspect. The bolt is retractably disposed within the lock body, and a rotating shaft drives the output shaft of a motor and the bolt. Attached Figure Description

[0036] A typical smart lock 1000 includes a lock body embedded in the door and a main control unlocking / locking mechanism and an emergency unlocking / locking mechanism installed on the door. The main control unlocking / locking mechanism is used for the regular unlocking and locking of the smart lock 1000, while the emergency unlocking / locking mechanism is used for emergency unlocking and locking. To facilitate emergency unlocking, existing smart locks 1000s often include a Type-C male connector 31, which connects to a mobile phone's data interface to collect the phone's identity information and obtain the power required for the locking module to operate. However, the Type-C male connector 31 protrudes from the lock body surface when connecting to the phone, making it less concealed and more prone to damage compared to a Type-C female connector.

[0037] Based on the above considerations, in order to facilitate user connection of the Type-C male connector 31 to the mobile phone's data interface when emergency unlocking is needed, and to improve the concealment of the Type-C male connector 31 and reduce the risk of damage to the Type-C male connector 31 when emergency unlocking is not required, this application provides an emergency unlocking module 100, including a bracket 10, a first elastic element 20, an electronic lock cylinder 30, a lock cylinder sleeve 40, a rotating shaft 50, and a locking mechanism 60. The lock cylinder sleeve 40 is sleeved outside the electronic lock cylinder 30 and is movably disposed within the bracket 10 along a first direction X, which is parallel to the axis of the lock cylinder sleeve 40. The electronic lock cylinder 30 includes a Type-C male connector 31 and a motor 32. The Type-C male connector 31 is electrically connected to the motor 32 and extends out of the lock cylinder sleeve 40. The rotating shaft 50 drives the output shaft of the motor 32 and the external structural components; the lock cylinder sleeve 40 has a locked position and an unlocked position. In the locked position, at least a portion of the Type-C male connector 31 is located within the bracket 10; in the unlocked position, the Type-C male connector 31 extends out of the bracket 10; the first elastic member 20 is used to drive the lock cylinder sleeve 40 to move towards the unlocked position; the locking mechanism 60 is disposed within the bracket 10 and is used to releasably lock the lock cylinder sleeve 40 when it is in the locked and unlocked positions.

[0038] Specifically, in case of emergency unlocking, the locking mechanism 60 releases the lock cylinder sleeve 40 from the locked position, causing it to move towards the unlocked position under the action of the first elastic element 20, allowing the Type-C male connector 31 to extend out of the bracket 10. The locking mechanism 60 then locks the lock cylinder sleeve 40 in the unlocked position, preventing the first elastic element 20 from compressing and causing the lock cylinder sleeve 40 to move towards the locked position when the user connects the Type-C male connector 31 to the phone's data interface. When emergency unlocking is not required, the locking mechanism 60 releases the lock cylinder sleeve 40 from the unlocked position, and then pressing the Type-C male connector 31 compresses the first elastic element 20, causing the lock cylinder sleeve 40 to move towards the locked position, placing the Type-C male connector 31 within the bracket 10. The locking mechanism 60 then locks the lock cylinder sleeve 40 in the locked position, preventing it from extending out of the bracket 10 under the action of the first elastic element 20.

[0039] In this emergency unlocking module 100, during emergency unlocking, the Type-C male connector 31 extends out of the bracket 10, and the locking mechanism 60 releasably locks the lock cylinder sleeve 40 in the unlocked position, facilitating the user's connection of the Type-C male connector 31 to the mobile phone's data interface, thus enabling emergency unlocking. During normal use, the Type-C male connector 31 is located within the bracket 10, and the locking mechanism 60 releasably locks the lock cylinder sleeve 40 in the closed position, reducing the risk of damage to the Type-C male connector 31 from external structural impacts and facilitating its concealment.

[0040] The electronic lock is described in detail below with reference to the accompanying drawings.

[0041] Please refer to Figures 1-4 , Figure 1 This is a schematic diagram of the structure of the emergency unlocking module 100 provided in some embodiments of this application. Figure 2 This is an exploded view of the structure of the emergency unlocking module 100 provided in some embodiments of this application. Figure 3 This is a cross-sectional view of the emergency unlocking module 100 when the lock cylinder sleeve 40 is in the locked position, provided in some embodiments of this application. Figure 4 This is a cross-sectional view of an emergency unlocking module 100 provided in some embodiments of this application when the lock cylinder sleeve 40 is in the unlocked position. Embodiments of this application provide an emergency unlocking module 100, including a bracket 10, a first elastic element 20, an electronic lock cylinder 30, a lock cylinder sleeve 40, a rotating shaft 50, and a locking mechanism 60. The lock cylinder sleeve 40 is sleeved outside the electronic lock cylinder 30 and movably disposed within the bracket 10 along a first direction X, which is parallel to the axis of the lock cylinder sleeve 40. The electronic lock cylinder 30 includes a Type-C male connector 31 and a motor 32. The Type-C male connector 31 is electrically connected to the motor 32 and extends out of the lock cylinder sleeve 40. The rotating shaft 50 drives the output shaft of the motor 32 and the external structural components; the lock cylinder sleeve 40 has a locked position and an unlocked position. In the locked position, at least a portion of the Type-C male connector 31 is located within the bracket 10; in the unlocked position, the Type-C male connector 31 extends out of the bracket 10; the first elastic member 20 is used to drive the lock cylinder sleeve 40 to move towards the unlocked position; the locking mechanism 60 is disposed within the bracket 10 and is used to releasably lock the lock cylinder sleeve 40 when it is in the locked and unlocked positions.

[0042] The bracket 10 is a shell-shaped structural component used to accommodate other structural components in the emergency unlocking module 100, providing assembly space for other structural components. For example, the bracket 10 is provided with a first receiving hole 11, and the first elastic member 20, the electronic lock cylinder 30 and the lock cylinder sleeve 40 are all disposed in the first receiving hole 11.

[0043] The electronic lock cylinder 30 is electrically connected to an external device (such as a mobile phone) to drive the lock tongue to unlock the structural components of the door.

[0044] The Type-C male connector 31 (Type-C Plug) is the plug portion of the USB Type-C interface. It is the end that inserts into the connector and is used to mate with the Type-C female connector on an external device.

[0045] For example, the external device can be a mobile phone or a Bluetooth electronic key.

[0046] In some embodiments, the external device is a mobile phone. The mobile phone is directly inserted into the Type-C male connector 31. After authorization by the mobile phone APP, communication is matched and power is supplied to the motor 32 to drive the rotating shaft 50 to rotate, thereby unlocking the door lock.

[0047] In some embodiments, the external device is a Bluetooth electronic key, and the electronic lock cylinder 30 also includes a circuit control module. The Type-C male connector 31 is electrically connected to the motor 32 through the circuit control module. When the Bluetooth electronic key is inserted into the Type-C male connector 31, the Bluetooth electronic key has unlocking permissions that match the circuit control module of the electronic lock cylinder 30, communication is matched, and power is supplied to the motor 32.

[0048] In some embodiments, the external device is a Bluetooth electronic key. The Bluetooth electronic key is inserted into the Type-C male connector 31 and connects to a mobile APP via Bluetooth. After authorization by the mobile APP, the Bluetooth electronic key supplies power to the motor 32 to unlock the electronic lock cylinder 30.

[0049] The lock cylinder sleeve 40 is a housing structure that is fitted over the electronic lock cylinder 30. For example, the lock cylinder sleeve 40 can be detachably connected to the electronic lock cylinder 30, or it can be integrally formed with the electronic lock cylinder 30.

[0050] The first direction X is the direction of movement of the lock cylinder sleeve 40. Understandably, the first elastic member 20 is compressed and stretched along the first direction X, and the axis of the rotating shaft 50 is parallel to the first direction X. For example, the first direction X can be the length direction of the bracket 10.

[0051] The first elastic element 20 can be a spring or a rubber structural component. For example, one end of the first elastic element 20 in the first direction X abuts against the lock cylinder sleeve 40, and the other end of the first elastic element 20 in the first direction X abuts against the bracket 10.

[0052] The rotating shaft 50 is a transmission structure used to transmit the rotation of the output shaft of the motor 32 to an external structural component (such as a lock tongue). In some embodiments, the rotating shaft 50 may include a first body 51 and a second body 52, wherein the first body 51 is connected to the output shaft of the motor 32, one end of the second body 52 is connected to the lock tongue, one end of the first body 51 is inserted into the other end of the second body 52 and can slide relative to the second body 52 along the axial direction of the rotating shaft 50, and the rotation of the first body 51 can drive the second body 52 to rotate, so that while the first elastic member 20 drives the lock cylinder sleeve 40 and the electronic lock cylinder 30 to switch between the unlocked and locked positions, the motor 32 of the electronic lock cylinder 30 can still be connected to the lock tongue through the rotating shaft 50.

[0053] For example, the first elastic element 20 is sleeved outside the rotating shaft 50, and the end of the rotating shaft 50 away from the electronic lock cylinder 30 passes through the bracket 10 and is connected to the lock tongue drive.

[0054] "In the locked position, at least a portion of the Type-C male connector 31 is located within the bracket 10" means that when the lock cylinder sleeve 40 is in the locked position, a portion of the Type-C male connector 31 is located within the bracket 10, or the entire Type-C male connector 31 is located within the bracket 10. In this case, the bracket 10 obstructs the Type-C male connector 31, preventing it from mating with the Type-C female connector of an external device (such as a mobile phone).

[0055] "In the unlocked position, the Type-C male connector 31 extends out of the bracket 10" means that when the lock cylinder sleeve 40 is in the unlocked position, the Type-C male connector 31 is completely exposed outside the bracket 10, and the bracket 10 does not block the Type-C male connector 31, so that the Type-C male connector 31 can be paired with the Type-C female connector of an external device (such as a mobile phone).

[0056] The locking mechanism 60 is a structure for releasably locking the lock cylinder sleeve 40 in an unlocked position and a locked position. For example, the locking mechanism 60 can be a solenoid. The lock cylinder sleeve 40 is provided with a first limiting hole and a second limiting hole arranged along a first direction X. The iron core of the solenoid is inserted into the first limiting hole under the action of its spring to lock the lock cylinder sleeve 40 in the locked position; the iron core of the solenoid is inserted into the second limiting hole under the action of its spring to lock the lock cylinder sleeve 40 in the unlocked position; the iron core of the solenoid is withdrawn from the first and second limiting holes under the action of the solenoid coil to release the lock cylinder sleeve 40.

[0057] Specifically, in case of emergency unlocking, the locking mechanism 60 releases the lock cylinder sleeve 40 from the locked position, allowing it to move towards the unlocked position under the action of the first elastic element 20, thus allowing the Type-C male connector 31 to extend out of the bracket 10. The locking mechanism 60 then locks the lock cylinder sleeve 40 in the unlocked position, preventing the first elastic element 20 from compressing and causing the lock cylinder sleeve 40 to move towards the locked position when the user connects the Type-C male connector 31 to the phone's data interface.

[0058] When emergency unlocking is not required, the locking mechanism 60 releases the lock cylinder sleeve 40 from the unlocked position. Then, pressing the Type-C male connector 31 compresses the first elastic element 20, causing the lock cylinder sleeve 40 to move towards the locked position, so that the Type-C male connector 31 is positioned within the bracket 10. The locking mechanism 60 then locks the lock cylinder sleeve 40 in the locked position, preventing it from extending out of the bracket 10 under the action of the first elastic element 20.

[0059] In this embodiment, during emergency unlocking, the Type-C male connector 31 extends out of the bracket 10, and the locking mechanism 60 releasably locks the lock cylinder sleeve 40 in the unlocked position, facilitating the user's connection of the Type-C male connector 31 to the mobile phone's data interface, thus enabling emergency unlocking. During normal use, the Type-C male connector 31 is located within the bracket 10, and the locking mechanism 60 releasably locks the lock cylinder sleeve 40 in the closed position, reducing the risk of damage to the Type-C male connector 31 from external structural impacts and facilitating the concealment of the Type-C male connector 31.

[0060] Please refer to Figures 2-4 Please refer to Figures 5-7 , Figure 5 This is a schematic diagram of the structure of a portion of the emergency unlocking module 100 when the locking mechanism 60 locks the lock cylinder sleeve 40, provided in some embodiments of this application. Figure 6 This is a schematic diagram of the structure of a portion of the emergency unlocking module 100 when the locking mechanism 60 releases the lock cylinder sleeve 40, provided in some embodiments of this application. Figure 7 This is a schematic diagram of the structure of the limiting pin 61 provided in some embodiments of this application. According to some embodiments of this application, the locking mechanism 60 includes a limiting pin 61, a second elastic member 62, and a limiting component 63. The limiting pin 61 is movably disposed within the bracket 10 along the second direction Y. The lock cylinder sleeve 40 is provided with a first limiting groove 41 and a second limiting groove 42. The limiting pin 61 is inserted into the first limiting groove 41 to lock the lock cylinder sleeve 40 in the locked position, and the limiting pin 61 is inserted into the second limiting groove 42 to lock the lock cylinder sleeve 40 in the unlocked position. The second direction Y is perpendicular to the first direction X. The second elastic member 62 is used to drive the limiting pin 61 to insert into the first limiting groove 41 or the second limiting groove 42. The limiting component 63 is used to releasably lock the limiting pin 61 when it is inserted into the first limiting groove 41 or the second limiting groove 42.

[0061] The limiting pin 61 is a pin-shaped structure that is movably disposed within the bracket 10 along the second direction Y.

[0062] The second elastic member 62 can be a spring or a rubber structural member. For example, one end of the second elastic member 62 in the second direction Y abuts against the limiting pin 61, and the other end of the first elastic member 20 in the second direction Y abuts against other structural members of the emergency unlocking module 100.

[0063] The second direction Y is the direction of movement of the limiting pin 61. Understandably, the second elastic member 62 is compressed and elongated along the second direction Y, and the axis of the limiting pin 61 is parallel to the second direction Y. For example, the second direction Y can be the width direction of the bracket 10.

[0064] In some embodiments, the bracket 10 is provided with a first receiving hole 11 and a second receiving hole 12. The first receiving hole 11 extends along a first direction X, and the second receiving hole 12 extends along a second direction Y. One end of the second receiving hole 12 is located on the hole wall of the first receiving hole 11. The lock cylinder sleeve 40 is provided with a first limiting groove 41 and a second limiting groove 42 on the side facing the second receiving hole 12. The limiting pin 61 and the second elastic member 62 are located inside the second receiving hole 12. One end of the limiting pin 61 extends out of the second receiving hole 12 and is inserted into the first limiting groove 41 or the second limiting groove 42.

[0065] For example, along the direction close to the axis of the lock cylinder sleeve 40, the size of the limiting pin 61 gradually decreases in the first direction X, so that when the lock cylinder sleeve 40 is in the locked position, the elastic force provided by the first elastic member 20 to the lock cylinder sleeve 40 can drive the limiting pin 61 to compress the second elastic member 62 and disengage from the first limiting groove 41. And when the lock cylinder sleeve 40 is in the unlocked position, the pressing force provided by a hand to the lock cylinder sleeve 40 can drive the limiting pin 61 to compress the second elastic member 62 and disengage from the second limiting groove 42.

[0066] The limiting component 63 is a component for releasably locking the limiting pin 61 when it is inserted into the first limiting groove 41 or the second limiting groove 42. For example, the limiting component 63 can be a solenoid, and the limiting pin 61 is provided with a third limiting hole arranged along the second direction Y. When the limiting pin 61 is inserted into the first limiting groove 41 or the second limiting groove 42, the third limiting hole aligns with the core of the solenoid, and the core of the solenoid is inserted into the third limiting hole under the action of its spring to lock the limiting pin 61; the core of the solenoid is withdrawn from the third limiting hole under the action of the solenoid coil to release the limiting pin 61.

[0067] In this embodiment, by providing a second elastic element 62, when the limiting pin 61 is aligned with the first limiting groove 41 or the second limiting groove 42, the limiting pin 61 can be inserted into the first limiting groove 41 or the second limiting groove 42 under the action of the second elastic element 62, thereby facilitating the locking of the limiting component 63 on the limiting pin 61, and thus facilitating the locking of the lock cylinder sleeve 40 in the locked position and the unlocked position. The structure is simple and easy to implement.

[0068] Please refer to Figures 2-7 According to some embodiments of this application, the first limiting groove 41 has a first guide surface 411 and a second guide surface 412 that are disposed opposite to each other in the first direction X, and the second limiting groove 42 has a third guide surface 421 and a fourth guide surface 422 that are disposed opposite to each other in the first direction X; along the axis away from the lock cylinder sleeve 40 pointing towards the limiting pin 61, the distance between the first guide surface 411 and the second guide surface 412 in the first direction X gradually increases, and the distance between the third guide surface 421 and the fourth guide surface 422 in the first direction X gradually increases.

[0069] For example, the first guide surface 411 is inclined toward the second limiting groove 42 along the axial direction away from the lock cylinder sleeve 40, the second guide surface 412 is inclined away from the second limiting groove 42 along the axial direction away from the lock cylinder sleeve 40, the third guide surface 421 is inclined away from the first limiting groove 41 along the axial direction away from the lock cylinder sleeve 40, and the fourth guide surface 422 is inclined toward the first limiting groove 41 along the axial direction away from the lock cylinder sleeve 40.

[0070] In this embodiment, by providing a first guide surface 411 and a second guide surface 412, and a third guide surface 421 and a fourth guide surface 422, when the limiting component 63 releases the limiting pin 61 and the lock cylinder sleeve 40 switches between the unlocked and locked positions under the action of external force (the elastic force of the first elastic member 20 or the user's pressing force), the first guide surface 411 and the second guide surface 412 can guide the limiting pin 61 to squeeze the second elastic member 62 to disengage from the first limiting groove 41, and the third guide surface 421 and the fourth guide surface 422 can guide the limiting pin 61 to squeeze the second elastic member 62 to disengage from the second limiting groove 42. This reduces the risk of the limiting pin 61 getting stuck in the first limiting groove 41 or the second limiting groove 42, and improves the smoothness of the lock cylinder sleeve 40 switching between the unlocked and locked positions.

[0071] Please refer to Figures 5-8 , Figure 8 This is a schematic diagram of the structure of a button 631 provided in some embodiments of this application. According to some embodiments of this application, the limiting component 63 includes a button 631, which is movably disposed within the bracket 10 along a first direction X. The button 631 includes a limiting portion 6311 and a clearance portion 6312 arranged along the first direction X. The button 631 has a first position and a second position. In the first position, the limiting portion 6311 abuts against the limiting pin 61 along the second direction Y to restrict the limiting pin 61 from disengaging from the first limiting groove 41 or the second limiting groove 42. In the second position, the clearance portion 6312 allows the limiting pin 61 to disengage from the first limiting groove 41 or the second limiting groove 42.

[0072] Button 631 is a structural component used for releasable limit pin 61.

[0073] In some embodiments, button 631 is located on the side of limit pin 61 in the third direction Z. The side of button 631 facing limit pin 61 has a first region and a second region arranged along the first direction X. The first region is provided with a protrusion to form a limiting portion 6311, and the second region forms a clearance portion 6312. In a first position, the first region is aligned with limit pin 61 in the first direction X, and the protrusion abuts against the surface of limit pin 61 away from lock cylinder sleeve 40 in the second direction Y to restrict limit pin 61 from disengaging from the first limiting groove 41 or the second limiting groove 42. In a second position, the second region is aligned with limit pin 61 in the first direction X, thereby allowing limit pin 61 to disengage from the first limiting groove 41 or the second limiting groove 42.

[0074] In some embodiments, the limiting pin 61 has a relief groove 611 on the side facing the button 631 in the third direction Z. In the first position, the protrusion forming the limiting portion 6311 is located in the relief groove 611, and the protrusion abuts against the first groove wall 611A of the relief groove 611 near the lock cylinder sleeve 40 in the second direction Y, so as to prevent the limiting pin 61 from disengaging from the first limiting groove 41 or the second limiting groove 42. In the second position, the protrusion forming the limiting portion 6311 disengages from the limiting groove.

[0075] Understandably, the first direction X, the second direction Y, and the third direction Z are all perpendicular to each other, and the third direction Z can be the thickness direction of the support 10.

[0076] In this embodiment, by providing a limiting part 6311 and a yielding part 6312 on the button 631, the operator can adjust the position of the button 631 by applying external force to the button 631, thereby adjusting the locking and releasing of the limiting pin 61. The structure is simple and easy to implement.

[0077] Please refer to Figures 5-8 According to some embodiments of this application, the limiting component 63 further includes a third elastic element 632, which is disposed within the bracket 10 and is used to drive the button 631 to move to the first position.

[0078] The third elastic member 632 can be a spring or a rubber structural member. For example, one end of the third elastic member 632 in the first direction X abuts against the button 631, and the other end of the first elastic member 20 in the first direction X abuts against the bracket 10.

[0079] In some embodiments, the bracket 10 is provided with a third receiving hole 13, which extends along a first direction X. The second receiving hole 12 and the third receiving hole 13 are located on one side of the first receiving hole 11 in a second direction Y. The third receiving hole 13 is located on the side of the second receiving hole 12 in a third direction Z. The third receiving hole 13 communicates with the second receiving hole 12. The button 631 and the third elastic member 632 are located in the third receiving hole 13.

[0080] In this embodiment, by providing a third elastic element 632, the button 631 can move towards the position of the locking limit pin 61 when the user does not apply external force to the button 631. Then, when the second elastic element 62 drives the limit pin 61 to insert into the first limit groove 41 or the second limit groove 42, the limiting part 6311 of the button 631 can lock the limit pin 61. The structure is simple and easy to implement.

[0081] Please refer to Figure 8 According to some embodiments of this application, the button 631 further includes a pressing part 6314 and a connecting part 6313. The pressing part 6314, the connecting part 6313, the clearance part 6312 and the limiting part 6311 are arranged sequentially along the first direction X. The pressing part 6314 is located outside the bracket 10, and the connecting part 6313 protrudes from the clearance part 6312 to form a first stepped surface 631A on the outer surface of the button 631. The projection of the first stepped surface 631A along the first direction X at least partially overlaps with the projection of the limiting pin 61.

[0082] The pressing part 6314 is the part of the button 631 that is exposed outside the bracket 10; the connecting part 6313 is the part of the button 631 that connects the pressing part 6314 and the clearance part.

[0083] For example, along the third direction Z, the connecting portion 6313 protrudes from the relief portion 6312 to form a first stepped surface 631A.

[0084] In this embodiment, when projected along the first direction X, the orthographic projection of the first step surface 631A at least partially overlaps with the orthographic projection of the limiting pin 61. This allows the first step surface 631A to abut against the limiting pin 61 when the user presses the button 631 to compress the third elastic member 632 and causes the button 631 to move to the second position, thereby preventing the risk of the button 631 excessively moving along the first direction X and crushing the third elastic member 632.

[0085] Please refer to Figures 9-11 , Figure 9 An exploded view of the structure of another emergency unlocking module 100 provided in some embodiments of this application. Figure 10 This is a cross-sectional view of an alternative emergency unlocking module 100 provided in some embodiments of this application when the lock cylinder sleeve 40 is in the locked position. Figure 11This is a cross-sectional view of another emergency unlocking module 100 provided in some embodiments of this application when the lock cylinder sleeve 40 is in the unlocked position. According to some embodiments of this application, the bracket 10 is provided with a first receiving hole 11 on one side in the first direction X, and the lock cylinder sleeve 40 is movably disposed in the first receiving hole 11; in the locked position, the Type-C male connector 31 is located in the first receiving hole 11; in the unlocked position, the Type-C male connector 31 extends out of the first receiving hole 11; the emergency unlocking module 100 also includes an outer cover 70, which is mounted on the outer surface of the bracket 10 and has a first through hole 711 corresponding to the first receiving hole 11, the diameter of the first through hole 711 being smaller than the diameter of the lock cylinder sleeve 40.

[0086] The outer cover 70 is a structural member disposed on the outside of the bracket 10. Exemplarily, the outer cover 70 may be detachably connected to the bracket 10, or the outer cover 70 may be non-detachably connected to the bracket 10.

[0087] In this embodiment, by setting the diameter of the first through hole 711 to be smaller than the diameter of the lock cylinder sleeve 40, the outer cover 70 can abut against the lock cylinder sleeve 40 when the first elastic member 20 drives the lock cylinder sleeve 40 to move to the unlock position, thereby preventing the lock cylinder sleeve 40 from disengaging from the first receiving hole 11 of the bracket 10.

[0088] Please refer to Figures 9-11 According to some embodiments of this application, the emergency unlocking module 100 further includes a rubber plug 80, which has a closed position for closing the first through hole 711 and an open position for opening the first through hole 711.

[0089] In this embodiment, by setting the rubber plug 80 to a closed position with the first through hole 711 closed, the risk of external dust falling on the Type-C male connector 31 can be reduced, and the concealment of the Type-C male connector 31 can be improved; by setting the rubber plug 80 to an open position with the first through hole 711 open, the risk of the rubber plug 80 interfering with the connection between external devices and the Type-C male connector 31 can be reduced.

[0090] Please refer to Figure 10 and Figure 11 According to some embodiments of this application, the bracket 10 is provided with a second receiving hole 12 on one side in the second direction Y. The second receiving hole 12 communicates with the first receiving hole 11. At least a portion of the locking mechanism 60 is received in the second receiving hole 12. The first direction X is perpendicular to the second direction Y. The outer cover 70 includes a first part 71 and a second part 72. The first through hole 711 is located in the first part 71. The second part 72 is bent relative to the first part 71 and extends along the first direction X, and blocks the second receiving hole 12.

[0091] In this embodiment, a second receiving hole 12 is provided to facilitate the installation of the locking mechanism 60. At the same time, the second part 72 of the outer cover 70 blocks the second receiving hole 12 to isolate the locking mechanism 60 from the external structure, which helps to improve the stability of the operation of the locking mechanism 60. The structure is simple and easy to implement.
