Description

Technical Field

[0001] This application relates to the field of lock technology, and more specifically, to an anti-collision device for a mechanical lock body. Background Technology

[0002] Existing mechanical lock bodies have a problem where the deadbolt (main bolt) and bolt can easily extend accidentally when the door is open. If the deadbolt extends accidentally, it is highly susceptible to damage upon impact with the door frame or wall, leading to damage to the deadbolt and the door itself, severely impacting the lock's lifespan and the door's integrity.

[0003] Therefore, how to reduce the risk of the bolt accidentally extending and hitting the door when the mechanical lock body is open is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides an anti-collision device for a mechanical lock body, which can reduce the risk of damage to the lock tongue due to its extension, thereby improving the reliability of the mechanical lock body.

[0005] This application is achieved through the following technical solution: This application provides an anti-collision device for a mechanical lock body. The anti-collision device includes a housing, a clutch plate, an anti-collision member, and a bolt, all of which are movably disposed within the housing. The bolt can extend out of the housing to lock and retract to unlock. The clutch plate has a first position allowing the bolt to lock and a second position holding the bolt unlocked. The anti-collision member is drivenly connected to the clutch plate and has a third position driving the clutch plate to the second position and a fourth position driving the clutch plate to the first position. When unlocking, the bolt retracts into the housing, the anti-collision member moves from the fourth position to the third position, and the anti-collision member drives the clutch plate from the first position to the second position. When locking, the anti-collision member moves from the third position to the fourth position, and the anti-collision member drives the clutch plate from the second position to the first position, allowing the bolt to extend out of the housing.

[0006] The technical solution of this application embodiment, by setting a clutch plate, allows the clutch plate to have a first position that allows the lock tongue to lock and a second position that keeps the lock tongue unlocked. By setting an anti-collision member to move the clutch plate between the first and second positions, the anti-collision member drives the clutch plate to move to the second position when unlocking, reducing the risk of damage caused by the lock tongue extending and improving the reliability of the mechanical lock body. At the same time, when locking, the anti-collision member drives the clutch plate to move to the first position, allowing the lock tongue to extend out of the housing to achieve locking, which improves the convenience of locking the mechanical lock body.

[0007] In some embodiments, the anti-collision member and the locking tongue are movably disposed in the housing along a first direction, and the clutch plate is movably disposed in the housing along a second direction, the first and second directions being perpendicular. The anti-collision member has a first mating portion, the clutch plate has a guide groove extending along the first direction, and the housing has a mating groove extending along the first direction. One end of the first mating portion passes through the guide groove and then enters the mating groove, and the first mating portion is movably disposed in the guide groove and the mating groove. When unlocking, the anti-collision member moves from a fourth position to a third position, and the first mating portion moves along the guide groove to drive the clutch plate from the first position to a second position. When locking, the anti-collision member moves from a third position to a fourth position, and the first mating portion moves along the guide groove to drive the clutch plate from the second position to the first position.

[0008] The technical solution of this application embodiment, by setting a first mating part and a guide groove and a mating groove that mate with the first mating part, enables the anti-collision member to drive the clutch plate to move to the second position through the first mating part when unlocking, and to drive the clutch plate to move to the first position through the first mating part when locking, which helps to improve the reliability and convenience of the anti-collision member driving the clutch plate.

[0009] In some embodiments, the anti-collision member and the locking tongue are movably disposed in the housing along a first direction, and the clutch plate is movably disposed in the housing along a second direction. The first and second directions are perpendicular. The locking tongue has a second mating portion, and the clutch plate has a movable groove extending along the first direction. When unlocking, the locking tongue retracts into the housing, and the second mating portion moves along the movable groove. When locking, the locking tongue extends out of the locking tongue housing, and the second mating portion moves along the movable groove.

[0010] The technical solution of this application embodiment, by setting a second mating part to cooperate with the movable groove, enables the bolt to extend out of the lock shell in the first direction to achieve locking, and the bolt to retract into the lock shell in the first direction to achieve unlocking, which helps to improve the reliability of unlocking and locking of the mechanical lock body.

[0011] In some embodiments, the clutch plate is further provided with a limiting groove extending along a second direction, one end of which communicates with a movable groove. When unlocking, the clutch plate moves from a first position to a second position, and the second engaging part enters the limiting groove from the movable groove. When locking, the clutch plate moves from the second position to the first position, and the second engaging part enters the movable groove from the limiting groove.

[0012] The technical solution of this application embodiment, by setting a limiting groove to cooperate with the second mating part, allows the second mating part to enter the limiting groove when unlocking, reducing the risk of damage caused by the bolt extending out, and improving the reliability of the mechanical lock body.

[0013] In some embodiments, the anti-collision member and the locking tongue are movably disposed on the housing along a first direction, and the clutch plate is movably disposed on the housing along a second direction, the first and second directions being perpendicular. The anti-collision device further includes a limiting member disposed on the housing. The clutch plate has a limiting hole extending along the second direction, and the limiting member is movably disposed in the limiting hole. In a first position, the limiting member abuts against one side wall of the limiting hole in the second direction. In a second position, the limiting member abuts against the other side wall of the limiting hole in the second direction.

[0014] The technical solution of this application embodiment, by setting a limiting member and a limiting hole to cooperate, allows the clutch plate to move in the second direction, which helps to improve the reliability and stability of the clutch plate switching between the first position and the second position.

[0015] In some embodiments, the anti-collision device further includes a return spring, which connects the housing and the anti-collision member. When locked, the anti-collision member moves from the third position to the fourth position, and the return spring stores force. When unlocked, the return spring drives the anti-collision member to move from the fourth position to the third position.

[0016] The technical solution of this application embodiment, by setting a reset spring to connect the housing and the anti-collision component, enables the anti-collision component to move from the fourth position to the third position, which helps to improve the convenience of the anti-collision component's reset.

[0017] In some embodiments, the anti-collision member includes a drive block and an anti-collision part, the anti-collision part being disposed on the drive block, and the drive block having a limiting boss. The housing has a guide groove, and the limiting boss is movably disposed in the guide groove.

[0018] The technical solution of this application embodiment, by setting a limiting boss that cooperates with the guide groove, enables the limiting boss to move along the guide groove, which helps to improve the reliability and stability of the movement of the anti-collision component.

[0019] In some embodiments, the anti-collision part is an anti-collision tongue, which is rotatably connected to the drive block and can extend out of the housing to abut against the door frame.

[0020] The technical solution of this application embodiment connects the anti-collision tongue to the drive block in a rotatable manner, so that when the anti-collision tongue abuts against the door frame, it can rotate relative to the drive block, reducing the risk of damage to the anti-collision tongue. At the same time, it can drive the drive block to move, so that the anti-collision member moves from the third position to the fourth position, which helps to improve the convenience of locking.

[0021] In some embodiments, the anti-collision part is a first magnetic element, and the door frame is provided with a second magnetic element, the first magnetic element and the second magnetic element have opposite magnetic properties.

[0022] The technical solution of this application embodiment, by setting a first magnetic component and a second magnetic component to cooperate, allows the anti-collision component to move from the third position to the fourth position when locking, which helps to improve the convenience of locking.

[0023] In some embodiments, the anti-collision device further includes a motor and a detection element. The motor is driven by the latch and is used to drive the latch to extend out of the housing. The detection element is signal-connected to the motor and is used to detect the operating status of the motor.

[0024] The technical solution of this application embodiment improves the convenience of locking by setting a motor-driven locking tongue. Simultaneously, by setting a detection component to detect the working status of the motor, the system can detect whether the mechanical lock body is locked, thereby improving the security of the mechanical lock body.

[0035] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the anti-collision device provided in some embodiments of this application. Figure 2 This is a schematic diagram illustrating the cooperation between the clutch plate and the anti-collision component provided in some embodiments of this application. Figure 3 This is a schematic diagram of the structure of the anti-collision device provided in some other embodiments of this application. Figure 4 This is a schematic diagram illustrating the cooperation of a clutch plate and a bumper in other embodiments of this application. This application provides a bumper device 1 for a mechanical lock body. The bumper device 1 includes a housing 10, a clutch plate 20, a bumper 30, and a bolt 40. The clutch plate 20, the bumper 30, and the bolt 40 are all movably disposed on the housing 10. The bolt 40 can extend out of the housing 10 to lock and can retract into the housing 10 to unlock. The clutch plate 20 has a first position allowing the bolt 40 to lock and a second position holding the bolt 40 unlocked. The bumper 30 is drively connected to the clutch plate 20 and has a third position driving the clutch plate 20 to the second position and a fourth position driving the clutch plate 20 to the first position. During unlocking, the bolt 40 retracts into the housing 10, the bumper 30 moves from the fourth position to the third position, and the bumper 30 drives the clutch plate 20 to move from the first position to the second position. When locked, the anti-collision member 30 moves from the third position to the fourth position, the anti-collision member 30 drives the clutch plate 20 to move from the second position to the first position, and the locking tongue 40 can extend out of the housing 10.

[0036] In some embodiments, the mechanical lock body can be installed on the door, with the bolt 40 extending out of the housing 10 and into the door frame 2 to lock the door. The bolt 40 retracts into the housing 10, that is, the bolt 40 exits the door frame 2, thus unlocking the door.

[0037] In some embodiments, the housing 10 may be made of metal, such as copper, iron, aluminum, stainless steel, etc.

[0038] In some embodiments, the clutch plate 20 may be made of metal, such as copper, iron, aluminum, stainless steel, etc.

[0039] In some embodiments, the material of the anti-collision component 30 can be metal, such as copper, iron, aluminum, stainless steel, etc.

[0040] In some embodiments, the latch 40 can be made of metal, such as copper, iron, aluminum, stainless steel, etc.

[0041] In some embodiments, the anti-collision member 30 and the locking tongue 40 can be movably disposed in the housing 10 in the same direction, the anti-collision member 30 and the locking tongue 40 can extend out of the housing 10 in the width direction of the door, and the clutch plate 20 can move relative to the housing 10 in the length direction of the door, and the clutch plate 20 is disposed inside the housing 10.

[0042] In some embodiments, the anti-collision member 30 is kinetically connected to the clutch plate 20. When the anti-collision member 30 moves from the third position to the fourth position, the anti-collision member 30 can drive the clutch plate 20 to move from the second position to the first position, allowing the locking tongue 40 to extend out of the housing 10. When the anti-collision member 30 moves from the fourth position to the third position, the anti-collision member 30 drives the clutch plate 20 to move from the first position to the second position, locking the locking tongue 40 within the housing 10.

[0043] During unlocking, the motor in the mechanical lock body drives the bolt 40 to retract into the housing 10, thereby unlocking the door. At this time, the door can be pushed to separate the door from the door frame 2. The anti-collision member 30 moves from the fourth position to the third position, and the anti-collision member 30 drives the clutch plate 20 to move from the first position to the second position, so that the clutch plate 20 keeps the bolt 40 inside the lock housing.

[0044] When locked, push the door body close to the door frame 2. The door frame 2 drives the anti-collision member 30 to move from the third position to the fourth position. The anti-collision member 30 drives the clutch plate 20 to move from the second position to the first position, so that the lock tongue 40 can extend out of the housing 10.

[0045] The technical solution of this application embodiment, by setting a clutch plate 20, allows the clutch plate 20 to have a first position that allows the bolt 40 to be locked and a second position that keeps the bolt 40 unlocked. By setting an anti-collision member 30 to move the clutch plate 20 between the first and second positions, when unlocking, the anti-collision member 30 drives the clutch plate 20 to move to the second position, reducing the risk of damage caused by the bolt 40 extending, and improving the reliability of the mechanical lock body. At the same time, when locking, the anti-collision member 30 drives the clutch plate 20 to move to the first position, allowing the bolt 40 to extend out of the housing 10 to achieve locking, which improves the convenience of locking the mechanical lock body.

[0046] Please refer to Figures 1 to 4 In some embodiments, the anti-collision member 30 and the locking tongue 40 are movably disposed on the housing 10 along a first direction X, and the clutch plate 20 is movably disposed on the housing 10 along a second direction Y, wherein the first direction X and the second direction Y are perpendicular. The anti-collision member 30 is provided with a first mating part 31, the clutch plate 20 is provided with a guide groove 21 extending along the first direction X, and the housing 10 is provided with a mating groove 12 extending along the first direction X. One end of the first mating part 31 passes through the guide groove 21 and then enters the mating groove 12, and the first mating part 31 is movably disposed in the guide groove 21 and the mating groove 12. When unlocking, the anti-collision member 30 moves from the fourth position to the third position, and the first mating part 31 moves along the guide groove 21 to drive the clutch plate 20 from the first position to the second position. When locking, the anti-collision member 30 moves from the third position to the fourth position, and the first mating part 31 moves along the guide groove 21 to drive the clutch plate 20 from the second position to the first position.

[0047] In some embodiments, the first direction X can be represented by the direction indicated by the letter X in the figure, and the second direction Y can be represented by the direction indicated by the letter Y in the figure. The first direction X can be parallel to the width direction of the door, the second direction Y can be parallel to the length direction of the door, and the first direction X and the second direction Y are perpendicular to each other.

[0048] In some embodiments, the first mating part 31 may be a protrusion that extends along the thickness direction of the clutch plate 20.

[0049] In some embodiments, the first mating part 31 can be integrally formed with the anti-collision member 30, or the first mating part 31 can be formed by welding or machining after the anti-collision member 30 is manufactured.

[0050] In some embodiments, the guide groove 21 can be integrally formed with the clutch plate 20, or the guide groove 21 can be formed by machining direction after the clutch plate 20 is machined.

[0051] In some embodiments, the mating groove 12 can be integrally formed with the housing 10, or the mating groove 12 can be formed by machining direction after the housing 10 is machined.

[0052] In some embodiments, the guide groove 21 may extend along a first direction X and be inclined in a second direction Y.

[0053] In some embodiments, the first mating part 31 extends along the thickness direction of the clutch plate 20. One end of the first mating part 31 passes through the guide groove 21 and enters the mating groove 12. The guide groove 21 and the mating groove 12 together guide the first mating part 31.

[0054] It should be noted that the first mating part 31 may only mate with the guide groove 21, or the clutch plate 20 may also have a straight groove extending along the first direction X, which may communicate with the guide groove 21. The first mating part 31 may pass through the guide groove 21 first and then enter the straight groove, or the first mating part 31 may pass through the straight groove first and then enter the guide groove 21. This allows the first mating part 31 to move a relatively long distance along the first direction X, thereby allowing the anti-collision member 30 to move a relatively long distance along the first direction X, while the clutch plate 20 moves a relatively small distance in the second direction Y.

[0055] When unlocking, the anti-collision member 30 moves from the fourth position to the third position, and the first mating part 31 moves along the guide groove 21. Since the anti-collision member 30 can only move along the first direction X, that is, the first mating part 31 can only move along the first direction X. The first mating part 31 abuts against the groove wall of the guide groove 21, thereby driving the clutch plate 20 to move along the second direction Y through the guide groove 21, so that the clutch plate 20 moves from the first position to the second position.

[0056] When locked, the anti-collision member 30 moves from the third position to the fourth position, the first mating part 31 moves along the guide groove 21, and the first mating part 31 abuts against the groove wall of the guide groove 21, thereby driving the clutch plate 20 to move along the second direction Y through the guide groove 21, so that the clutch plate 20 moves from the second position to the first position.

[0057] The technical solution of this application embodiment, by setting a first mating part 31 and a guide groove 21 and a mating groove 12 that mate with the first mating part 31, enables the anti-collision member 30 to drive the clutch plate 20 to move to the second position through the first mating part 31 when unlocking, and to drive the clutch plate 20 to move to the first position through the first mating part 31 when locking, which helps to improve the reliability and convenience of the anti-collision member 30 driving the clutch plate 20.

[0058] Please refer to Figures 1 to 4 In some embodiments, the anti-collision member 30 and the locking tongue 40 are movably disposed on the housing 10 along a first direction X, and the clutch plate 20 is movably disposed on the housing 10 along a second direction Y. The first direction X and the second direction Y are perpendicular. The locking tongue 40 is provided with a second mating part 41, and the clutch plate 20 is provided with a movable groove 22, which extends along the first direction X. When unlocking, the locking tongue 40 retracts into the housing 10, and the second mating part 41 moves along the movable groove 22. When locking, the locking tongue 40 extends out of the housing 10, and the second mating part 41 moves along the movable groove 22.

[0059] In some embodiments, the second mating part 41 may be a protrusion that extends along the thickness direction of the clutch plate 20.

[0060] In some embodiments, the second mating part 41 may be integrally formed with the latch 40, or the second mating part 41 may be formed by welding or machining after the latch 40 has been machined.

[0061] In some embodiments, the movable groove 22 can be integrally formed with the clutch plate 20, or the movable groove 22 can be formed by machining direction after the clutch plate 20 is machined.

[0062] When unlocking or locking, the second mating part 41 moves along the movable groove 22, which extends along the first direction X, causing the second mating part 41 to move along the first direction X, and causing the locking tongue 40 to move along the first direction X, thus guiding the movement of the locking tongue 40.

[0063] The technical solution of this application embodiment, by setting the second mating part 41 to cooperate with the movable groove 22, enables the bolt 40 to extend out of the lock shell along the first direction X to achieve locking, and the bolt 40 to retract into the lock shell along the first direction X to achieve unlocking, which helps to improve the reliability of the mechanical lock body unlocking and locking.

[0064] Please refer to Figures 1 to 4 In some embodiments, the clutch plate 20 is further provided with a limiting groove 23, which extends along the second direction Y, and one end of the limiting groove 23 in the second direction Y communicates with the movable groove 22. When unlocking, the clutch plate 20 moves from the first position to the second position, and the second mating part 41 enters the limiting groove 23 from the movable groove 22. When locking, the clutch plate 20 moves from the second position to the first position, and the second mating part 41 enters the movable groove 22 from the limiting groove 23.

[0065] In some embodiments, the limiting groove 23 can be integrally formed with the clutch plate 20, or the limiting groove 23 can be formed by machining direction after the clutch plate 20 is machined.

[0066] When unlocking, the clutch plate 20 moves from the first position to the second position, that is, the clutch plate 20 moves relative to the second mating part 41, so that the second mating part 41 enters the limiting groove 23 from the movable groove 22. The groove wall of the limiting groove 23 in the first direction X abuts against the second mating part 41, so that the second mating part 41 cannot move along the first direction X, that is, the locking tongue 40 cannot extend out of the housing 10 along the first direction X.

[0067] When locked, the clutch plate 20 moves from the second position to the first position, that is, the clutch plate 20 moves relative to the second mating part 41, so that the second mating part 41 enters the movable groove 22 from the limiting groove 23. The groove wall of the limiting groove 23 in the first direction X separates from the second mating part 41, so that the second mating part 41 can move along the first direction X, that is, the locking tongue 40 can extend out of the housing 10 along the first direction X.

[0068] The technical solution of this application embodiment, by setting a limiting groove 23 to cooperate with the second mating part 41, allows the second mating part 41 to enter the limiting groove 23 when unlocking, reducing the risk of damage caused by the extension of the lock tongue 40, and improving the reliability of the mechanical lock body.

[0069] Please refer to Figures 1 to 4 In some embodiments, the anti-collision member 30 and the locking tongue 40 are movably disposed on the housing 10 along a first direction X, and the clutch plate 20 is movably disposed on the housing 10 along a second direction Y, wherein the first direction X and the second direction Y are perpendicular. The anti-collision device 1 also includes a limiting member 50 disposed on the housing 10. The clutch plate 20 is provided with a limiting hole 24 extending along the second direction Y, and the limiting member 50 is movably disposed in the limiting hole 24. In a first position, the limiting member 50 abuts against one side wall of the limiting hole 24 in the second direction Y. In a second position, the limiting member 50 abuts against the other side wall of the limiting hole 24 in the second direction Y.

[0070] In some embodiments, the number of limiting members 50 can be multiple, and the multiple limiting members 50 are arranged at intervals along the second direction Y. Correspondingly, the number of limiting holes 24 is also multiple.

[0071] In some embodiments, the limiting member 50 may be a protrusion that extends along the thickness direction of the clutch plate 20.

[0072] In some embodiments, the limiting member 50 can be integrally formed with the housing 10, or the limiting member 50 can be formed by welding or machining after the housing 10 is manufactured.

[0073] In some embodiments, the limiting hole 24 can be integrally formed with the clutch plate 20, or the limiting hole 24 can be formed by machining direction after the clutch plate 20 is machined.

[0074] In some embodiments, the limiting hole 24 extends along the second direction Y. During unlocking, the anti-collision member 30 drives the clutch plate 20 to move. Because the limiting member 50 engages with the limiting hole 24, the limiting hole 24 can only move along the second direction Y, thus ensuring that the clutch plate 20 can only move along the second direction Y. When the clutch plate 20 moves to the second position, the limiting member 50 abuts against one side wall of the limiting hole 24 in the second direction Y. During unlocking, the anti-collision member 30 drives the clutch plate 20 to move. Because the limiting member 50 engages with the limiting hole 24, the limiting hole 24 can only move along the second direction Y, thus ensuring that the clutch plate 20 can only move along the second direction Y. When the clutch plate 20 moves to the first position, the limiting member 50 abuts against the other side wall of the limiting hole 24 in the second direction Y.

[0075] It should be noted that a limiting member 50 is provided on one side of the housing 10 along the thickness direction of the clutch plate 20, and a groove may be provided on the other side of the housing 10. One end of the limiting member 50 passes through the limiting hole 24 and cooperates with the groove.

[0076] The technical solution of this application embodiment, by setting the limiting member 50 to cooperate with the limiting hole 24, allows the clutch plate 20 to move along the second direction Y, which helps to improve the reliability and stability of the clutch plate 20 switching between the first position and the second position.

[0077] Please refer to Figures 1 to 4 In some embodiments, the anti-collision device 1 further includes a return spring 60, which connects the housing 10 and the anti-collision member 30. When locked, the anti-collision member 30 moves from the third position to the fourth position, and the return spring 60 stores force. When unlocked, the return spring 60 drives the anti-collision member 30 to move from the fourth position to the third position.

[0078] In some embodiments, the housing 10 may be provided with a baffle 13, which may be integrally formed with the housing 10, or may be connected to the housing 10 by welding, bonding or bolting after the housing 10 is manufactured. The baffle 13 may protrude from the housing 10, one end of the return spring 60 is connected to the baffle 13, and the other end of the return spring 60 is connected to the anti-collision member 30.

[0079] When locked, pushing the door closer to the door frame 2 causes the door frame 2 to move the anti-collision member 30 from the third position to the fourth position, and the return spring 60 stores force. The return spring 60 then drives the anti-collision member 30 from the fourth position to the third position.

[0080] The technical solution of this application embodiment, by setting a reset spring 60 to connect the housing 10 and the anti-collision member 30, enables the anti-collision member 30 to move from the fourth position to the third position, which helps to improve the convenience of the reset of the anti-collision member 30.

[0081] Please refer to Figures 1 to 4 In some embodiments, the anti-collision member 30 includes a driving block 32 and an anti-collision part 33, the anti-collision part 33 being disposed on the driving block 32, and the driving block 32 having a limiting boss 321. The housing 10 has a guide groove 11, and the limiting boss 321 is movably disposed in the guide groove 11.

[0082] In some embodiments, the anti-collision part 33 is disposed on the drive block 32, and the disposal method may be snap-fit, bolt connection, welding, etc.

[0083] In some embodiments, the housing 10 is provided with a guide groove 11. The guide groove 11 can be integrally formed with the housing 10, or the guide groove 11 can be formed by machining direction after the housing 10 is machined.

[0084] In some embodiments, the guide groove 11 may extend along a first direction X.

[0085] In some embodiments, the drive block 32 is provided with a limiting boss 321. The limiting boss 321 can be integrally formed with the drive block 32, or the limiting boss 321 can be formed by welding or machining after the drive block 32 is processed.

[0086] In some embodiments, when the anti-collision member 30 moves from the third position to the fourth position, or from the fourth position to the third position, the limiting boss 321 cooperates with the guide groove 11, so that the limiting boss 321 can only move along the first direction X, which means that the anti-collision member 30 can only move along the first direction X, thus guiding the movement of the anti-collision member 30.

[0087] It should be noted that the anti-collision device 1 may also include a stop strip 90, which is disposed on the outside of the housing 10. The stop strip 90 has a through hole for accommodating the anti-collision member 30 and the latch 40. When the anti-collision member 30 or the latch 40 extends out of the housing 10, the anti-collision member 30 or the latch 40 can pass through the through hole and cooperate with the door frame 2. The stop strip 90 is used to cooperate with the drive block 32, so that when the anti-collision member 30 extends out of the housing 10, the drive block 32 abuts against the stop strip 90, preventing the drive member from fully extending out of the housing 10 and reducing the risk of the anti-collision member 30 detaching from the housing 10. Similarly, the latch 40 may also be connected to a stop, so that when the latch 40 extends out of the housing 10, the stop abuts against the stop strip 90, preventing the stop from fully extending out of the housing 10 and reducing the risk of the latch 40 detaching from the housing 10.

[0088] The technical solution of this application embodiment, by setting a limiting boss 321 to cooperate with the guide groove 11, enables the limiting boss 321 to move along the guide groove 11, which helps to improve the reliability and stability of the movement of the anti-collision member 30.

[0089] Please refer to Figure 1 and Figure 2 In some embodiments, the anti-collision part 33 is an anti-collision tongue 331, which is rotatably connected to the drive block 32. The anti-collision tongue 331 can extend out of the housing 10 to abut against the door frame 2.

[0090] In some embodiments, the anti-collision tongue 331 may be provided with a channel, and the drive block 32 may be provided with a rotating shaft, which cooperates with the channel so that the anti-collision tongue 331 can rotate relative to the drive block 32.

[0091] When the anti-collision tongue 331 comes into contact with the door frame 2, the anti-collision tongue 331 can rotate relative to the drive block 32, thereby buffering the impact between the door frame 2 and the anti-collision tongue 331. Since the anti-collision member 30 can only move along the first direction X, after the door frame 2 comes into contact with the anti-collision tongue 331, the anti-collision member 30 is forced to retract into the housing 10 along the first direction X.

[0092] In some embodiments, the anti-collision tongue 331 may be provided with a slope that abuts against the door frame 2, thereby further buffering the impact between the door frame 2 and the anti-collision tongue 331.

[0093] The technical solution of this application embodiment rotatably connects the anti-collision tongue 331 to the drive block 32, so that when the anti-collision tongue 331 abuts against the door frame 2, it can rotate relative to the drive block 32, reducing the risk of damage to the anti-collision tongue 331. At the same time, it can drive the drive block 32 to move, so that the anti-collision member 30 moves from the third position to the fourth position, which helps to improve the convenience of locking.

[0094] Please refer to Figure 3 and Figure 4In some embodiments, the anti-collision part 33 is a first magnetic element 332, and the door frame 2 is provided with a second magnetic element 2a. The first magnetic element 332 and the second magnetic element 2a have opposite magnetic properties.

[0095] In some embodiments, the first magnetic element 332 and the second magnetic element 2a may both be magnets, and the magnetism of the first magnetic element 332 and the second magnetic element 2a is opposite.

[0096] When locked, when the anti-collision part 33 approaches the door frame 2, the second magnetic element 2a drives the first magnetic element 332 to move away from the door frame 2, thereby causing the anti-collision part 30 to move from the third position to the fourth position.

[0097] The technical solution of this application embodiment, by setting the first magnetic element 332 and the second magnetic element 2a to cooperate, allows the anti-collision element 30 to move from the third position to the fourth position when locked, which helps to improve the convenience of locking.

[0098] Please refer to Figures 1 to 4 In some embodiments, the anti-collision device 1 further includes a motor (not shown) and a detection element (not shown). The motor is driven by the latch 40 and is used to drive the latch 40 out of the housing 10. The detection element is signal-connected to the motor and is used to detect the operating status of the motor.

[0099] In some embodiments, the detection element can be a sensor to detect the motor's speed, number of rotations, etc.

[0100] In some embodiments, the connection between the detection device and the motor signal can be a wiring harness connection, a WiFi connection, a Bluetooth connection, or the like.

[0101] When locked, the door body approaches the door frame 2, and the door frame 2 drives the anti-collision member 30 to move from the third position to the fourth position. At this time, the return spring 60 stores force. The anti-collision member 30 drives the clutch plate 20 to move from the second position to the first position, and the motor drives the lock tongue 40 to extend out of the housing 10 and cooperate with the door frame 2 to achieve locking.

[0102] When unlocking, the motor drives the latch 40 to retract into the housing 10, the return spring 60 drives the anti-collision member 30 to move from the fourth position to the third position, and the anti-collision member 30 drives the clutch plate 20 to move from the first position to the second position.

[0103] It should be noted that the mechanical lock body can be equipped with an automatic closing function. When unlocked, and the door body does not return to its original position to engage with the door frame 2 (i.e., the door body remains in the open state), the anti-collision member 30 is in the third position, and the clutch plate 20 is in the second position. At this time, the automatic closing function of the mechanical lock body is activated, and the motor rotates to drive the bolt 40 to extend out of the housing 10. However, because the clutch plate 20 is in the second position, the bolt 40 cannot extend out of the housing 10, meaning the motor cannot rotate. The detection device detects that the motor cannot rotate and can transmit this information to the door lock or the user's receiver, issuing an alarm that the door is in the open state.

[0104] The technical solution of this application embodiment improves the convenience of locking by setting a motor-driven locking tongue 40. Simultaneously, by setting a detection component to detect the working status of the motor, the system can detect whether the mechanical lock body is locked, thereby improving the security of the mechanical lock body.

[0105] In some embodiments, the number of locking tongues 40 can be two, one of which can be a deadbolt and the other can be a square bolt. Both the deadbolt and the square bolt are movably disposed in the housing 10 along the first direction X.

[0106] It should be noted that the solution proposed in this application can improve the structure of the original mechanical lock body, and can lock both the deadbolt and the bolt simultaneously. When the deadbolt and the bolt are unlocked, the extension and retraction of the bolt and the deadbolt will not affect each other, and there is no difference from the unlocking and locking method of the original mechanical lock body, thus avoiding affecting the user's operating experience.

[0107] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
