Abstract

This utility model discloses an anti-forced unlocking structure and a smart door lock, relating to the field of smart door lock technology. The anti-forced unlocking structure includes a first rotating shaft group, a second rotating shaft group, and a movable structural member. The first rotating shaft group is connected to the handle and rotates under the drive of the handle. The second rotating shaft group is driven by the lock body. The movable structural member is movably installed on the first rotating shaft group. The movable structural member is configured such that when the rotation stroke of the handle exceeds the unlocking stroke range, the movable structural member deviates from or disengages from the second rotating shaft group, causing the first rotating shaft group to disengage from the second rotating shaft group. The first rotating shaft group then rotates freely relative to the second rotating shaft group, while the second rotating shaft group does not rotate. Consequently, the lock body, which is driven by the second rotating shaft group, also does not rotate, thus preventing forced unlocking. This improves the protection and security performance of the smart door lock. Furthermore, the lock body remains undamaged, eliminating the need for lock body replacement and extending the lock body's service life.

Description

Technical Field

[0001] This utility model relates to the field of smart door lock technology, and in particular to a structure for preventing forced unlocking and a smart door lock. Background Technology

[0002] With the popularization of smart homes, smart door locks have become mainstream products due to their convenience. However, in daily use, attackers may forcefully press down on the handle of smart door locks, causing axial pressure on the handle and transmitting it to the inside of the lock body. This stress concentration within the lock body can lead to damage or destruction. Therefore, smart door locks on the market pose significant security risks.

[0003] Existing solutions mostly employ methods such as reinforcing the lock body's outer shell or adding anti-pry sensors for protection. However, when an attacker forcibly presses down on the handle of an existing smart lock, the axial pressure on the handle is still transmitted to the inside of the lock body, causing internal damage and destruction. Clearly, existing smart locks have poor protection capabilities and low security performance. Utility Model Content

[0004] The main purpose of this utility model is to propose an anti-violent unlocking structure and a smart door lock, aiming to solve the problems of poor protection and low security performance of existing smart door locks.

[0005] To achieve the above objectives, the anti-violent unlocking structure proposed in this utility model includes a first rotating shaft group, a second rotating shaft group, and a movable structural member. The first rotating shaft group is connected to the handle and is driven to rotate by the handle. The second rotating shaft group is connected to the lock body and is used to drive the lock body to perform unlocking or locking actions. The movable structural member is movably installed on the first rotating shaft group.

[0006] The movable structural member is configured such that: when the rotation stroke of the handle is within the locking stroke range, the movable structural member is linked with the second rotating shaft group to drive the first rotating shaft group and the second rotating shaft group, so that the rotation of the first rotating shaft group drives the second rotating shaft group to rotate synchronously; when the rotation stroke of the handle exceeds the unlocking stroke range, the movable structural member deviates from or disengages from the second rotating shaft group relative to the second rotating shaft group, so that the first rotating shaft group and the second rotating shaft group are disengaged from the drive connection, and the first rotating shaft group rotates freely relative to the second rotating shaft group.

[0007] In some embodiments, the movable structural member is provided with a deflector, which is rotatably mounted on the first rotating shaft group. The deflector is configured such that: when the rotation stroke of the handle is within the locking stroke range, the deflector rotates with the first rotating shaft group, and a portion of the deflector abuts against the second rotating shaft group to push the second rotating shaft group to rotate; when the rotation stroke of the handle exceeds the unlocking stroke range, the deflector deflects relative to the second rotating shaft group to disengage from the linkage with the second rotating shaft group.

[0008] In some embodiments, the movable structural member is further provided with a driving member, which is disposed on the first rotating shaft group; the deflector is provided with a rotation fulcrum rotatably connected to the first rotating shaft group; the deflector has a main body, a first end located on one side of the main body and a second end on the opposite side, the first end extending to a position adjacent to the driving member and forming a first force-bearing arm that is abutted and force-applied by the driving member; the second end extending to a position adjacent to the second rotating shaft group and forming a second force-output arm that pushes the second rotating shaft group.

[0009] The movable structural member is configured such that: when the rotation stroke of the handle is within the locking stroke range, the driving member rotates with the first rotating shaft group to act on the first end, and the second end abuts against the second rotating shaft group to push the second rotating shaft group to rotate; when the rotation stroke of the handle exceeds the unlocking stroke range, the second end is pushed by the second rotating shaft group and deflects around the rotation fulcrum, the first end disengages from the driving member, and the deflecting member slides relative to the second rotating shaft group, causing the first rotating shaft group to rotate freely relative to the second rotating shaft group.

[0010] In some embodiments, the rotating component is a dial wheel, and the first end is provided with a deflection hole that limits the deflection range of the dial wheel; the driving component is positioned in the deflection hole and in the deflection path of the first end, so as to act on the first end when the rotation stroke of the handle is within the locking stroke range.

[0011] In some embodiments, the second rotating shaft assembly includes a shaft body and a circumferentially oriented limiting groove provided on the shaft body, the limiting groove having two opposing side walls; the second end abuts against one of the side walls to be pushed by the driving member, driving the second rotating shaft assembly to rotate; or the second end is pushed by the other side wall and deflects around the rotation fulcrum, causing the second end to disengage from the limiting groove and slide relative to the second rotating shaft assembly.

[0012] In some embodiments, the outer periphery of the second rotating shaft assembly is provided with a protruding ring structure, which is configured to avoid the limiting groove.

[0013] In some embodiments, the first pivot assembly includes a base and a shaft portion, the shaft portion being connected to the handle, the base being disposed at the end of the shaft portion opposite to the handle, and the base being provided with a receiving groove for the deflection movement of the dial wheel.

[0014] In some embodiments, there are two receiving slots, which are mirror images of each other along the central axis of the base; two second ends are provided, which are mirror images of each other along the deflection center axis of the rotary member.

[0015] In some embodiments, the anti-violent unlocking structure further includes a drive device, a push block, and a telescopic pin. The output end of the drive device is connected to the push block to drive the push block to move. The first rotating shaft group is provided with a first connecting groove, and the second rotating shaft group is provided with a second connecting groove corresponding to the first connecting groove. The telescopic pin is provided in the first connecting groove. The telescopic pin is pushed by the push block and extends into the second connecting groove to connect the first rotating shaft group and the second rotating shaft group; or the telescopic pin extends out from the second connecting groove.

[0016] In some embodiments, a reset member is installed in the first connecting groove, the reset member being used to reset the telescopic pin extending into the second connecting groove in a direction away from the second rotating shaft assembly.

[0017] In some embodiments, there are two second connecting slots, which are arranged perpendicularly to each other, with one of the second connecting slots corresponding to the first connecting slot.

[0018] This utility model also proposes an intelligent door lock, which includes a handle, a lock body, a faceplate, and an anti-violent unlocking structure. The first rotating shaft assembly is rotatably mounted on the side of the faceplate facing the lock body. The handle is mounted on the other side of the faceplate and connected to the first rotating shaft assembly. The lock body is drivenly connected to the second rotating shaft assembly. A limiting space is provided on the side of the faceplate facing the first rotating shaft assembly, and the first rotating shaft assembly rotates in the limiting space.

[0019] This invention employs a method where the handle is connected to a first rotating shaft group, the lock body is connected to a second rotating shaft group, and a movable structural component is added. This movable structural component is movably mounted on the first rotating shaft group. The movable structural component is configured such that: when the handle's rotation stroke is within the locking range, it links with the second rotating shaft group, connecting them and allowing the rotation of the first rotating shaft group to synchronously rotate the second rotating shaft group; when the handle's rotation stroke exceeds the unlocking range, the movable structural component deviates from or disengages from the second rotating shaft group, disengaging the first and second rotating shaft groups and allowing the first rotating shaft group to rotate freely relative to the second rotating shaft group. Therefore, when the handle is forcefully pressed down to unlock, the first and second rotating shaft groups disengage, the first rotating shaft group rotates freely relative to the second rotating shaft group, the second rotating shaft group does not rotate, and the lock body, which is connected to the second rotating shaft group, does not rotate, resulting in unlocking failure. This improves the protection and security performance of the smart lock. Furthermore, when the handle is pressed down forcefully, the lock body is not damaged or destroyed, so there is no need to replace the lock body, which allows for continued use of the lock body and extends its service life.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0038] With the popularization of smart homes, smart door locks have become mainstream products due to their convenience. However, in daily use, attackers may forcefully press down on the handle 60 of smart door locks on the market. The handle 60 is subjected to axial pressure, which is transmitted to the inside of the lock body, causing stress concentration inside the lock body and resulting in damage or destruction. Therefore, smart door locks on the market pose a significant security risk.

[0039] Existing solutions mostly employ methods such as reinforcing the lock body's outer shell or adding anti-pry sensors for protection. However, when an attacker forcibly presses down on the handle 60 of the existing smart lock 101, the axial pressure on the handle 60 is still transmitted to the inside of the lock body, causing damage and destruction to the internal components. Therefore, the existing smart lock 101 exhibits poor protection capabilities and low security performance.

[0040] This utility model proposes an anti-violent unlocking structure 100. Please refer to [link / reference]. Figure 1 In one embodiment of this utility model, the anti-violent unlocking structure 100 includes a first rotating shaft group 20, a second rotating shaft group 30, and a movable structural member 40. The first rotating shaft group 20 is connected to the handle 60 and is driven to rotate by the handle 60. The second rotating shaft group 30 is connected to the lock body and is used to drive the lock body to perform unlocking or locking actions. The movable structural member 40 is movably installed on the first rotating shaft group 20.

[0041] Please see Figure 3 and Figure 4The movable structural member 40 is movably mounted on the first rotating shaft group 20. The movable structural member 40 is configured such that when the rotation stroke of the handle 60 is within the locking stroke range, the movable structural member 40 is linked with the second rotating shaft group 30 to drive the first rotating shaft group 20 and the second rotating shaft group 30, so that the rotation of the first rotating shaft group 20 drives the second rotating shaft group 30 to rotate synchronously; when the rotation stroke of the handle 60 exceeds the unlocking stroke range, the movable structural member 40 deviates from or disengages from the second rotating shaft group 30 relative to the second rotating shaft group 30, so that the first rotating shaft group 20 and the second rotating shaft group 30 are disengaged from the drive connection, and the first rotating shaft group 20 rotates freely relative to the second rotating shaft group 30.

[0042] Optionally, the movable structural member 40 can be a telescopic structural member with a telescopic function, which is mounted on the first rotating shaft group 20. When the rotation stroke of the handle 60 is within the locking stroke range, one end of the telescopic structural member extends under the force of the spring and engages or abuts with the second rotating shaft group 30, so that the telescopic structural member and the second rotating shaft group 30 are linked to achieve locking. When the rotation stroke of the handle 60 exceeds the unlocking stroke range, one end of the telescopic structural member can be pushed by the drive device 11 or pushed out by the push block 12 on the second rotating shaft group 30, and retract towards the first rotating shaft group 20, so that the first rotating shaft group 20 and the second rotating shaft group 30 are disengaged from the transmission connection. The first rotating shaft group 20 rotates freely, and the second rotating shaft group 30 does not rotate. The lock body does not perform the unlocking or locking action, thereby avoiding forced unlocking.

[0043] The movable structural member 40 can also be a rotating member 41, which can be positioned between the first rotating shaft group 20 and the second rotating shaft group 30. When the rotation stroke of the handle 60 is within the locking stroke range, both ends of the rotating member 41 abut against the first rotating shaft group 20 and the second rotating shaft group 30 respectively, so that the rotating member 41 is limited between the first rotating shaft group 20 and the second rotating shaft group 30. The first rotating shaft group 20 is connected to the second rotating shaft group 30 through the rotating member 41 to achieve locking. When the rotation stroke of the handle 60 exceeds the unlocking stroke range, the rotating member 41 deflects, causing both ends of the rotating member 41 to separate from the first rotating shaft group 20 and the second rotating shaft group 30. This prevents the torque of the first rotating shaft group 20 from being transmitted to the second rotating shaft group 30 through the rotating member 41. The first rotating shaft group 20 rotates freely relative to the second rotating shaft group 30, the second rotating shaft group 30 does not rotate, and the lock body connected to the second rotating shaft group 30 does not rotate, thus failing to unlock by force. Among them, the shifting component 41 can be a lever, a paddle, a cam, or a dial, etc.

[0044] The technical solution of this utility model involves connecting the handle 60 to the first rotating shaft group 20, connecting the lock body to the second rotating shaft group 30, and adding a movable structural member 40. The movable structural member 40 is movably installed on the first rotating shaft group 20. The movable structural member 40 is configured such that: when the rotation stroke of the handle 60 is within the locking stroke range, the movable structural member 40 is linked with the second rotating shaft group 30 to drive the first rotating shaft group 20 and the second rotating shaft group 30, so that the rotation of the first rotating shaft group 20 drives the second rotating shaft group 30 to rotate synchronously; when the rotation stroke of the handle 60 exceeds the unlocking stroke range, the movable structural member 40 deviates from or disengages from the second rotating shaft group 30 relative to the second rotating shaft group 30, so that the first rotating shaft group 20 and the second rotating shaft group 30 are disengaged from the drive connection, and the first rotating shaft group 20 rotates freely relative to the second rotating shaft group 30. Therefore, when the handle 60 is forcibly pressed down to unlock, the first pivot assembly 20 and the second pivot assembly 30 disengage from their transmission connection. The first pivot assembly 20 rotates freely relative to the second pivot assembly 30, while the second pivot assembly 30 does not rotate. Consequently, the lock body, which is connected to the second pivot assembly 30, also does not rotate. Forced unlocking fails, thus improving the protection capability and security of the smart door lock 101. Furthermore, the lock body remains undamaged and uninjured when the handle 60 is forcibly pressed down, eliminating the need for lock body replacement and allowing for continued use, thereby extending the lock body's lifespan.

[0045] In some embodiments, the movable structural member 40 is provided with a deflector 41, which is rotatably mounted on the first rotating shaft assembly 20. The deflector 41 is configured such that when the rotation stroke of the handle 60 is within the locking stroke range, the deflector 41 rotates with the first rotating shaft assembly 20, and a portion of the structure of the deflector 41 abuts against the second rotating shaft assembly 30 to push the second rotating shaft assembly 30 to rotate; when the rotation stroke of the handle 60 exceeds the unlocking stroke range, the deflector 41 deflects relative to the second rotating shaft assembly 30 to disengage from the linkage with the second rotating shaft assembly 30.

[0046] In some embodiments, please refer to Figure 3 and Figure 4 When locking, lift handle 60 upwards; when forcibly unlocking, turn handle 60 downwards.

[0047] When locking, the handle 60 is lifted upward by an external force, and the rotation stroke of the handle 60 is within the locking stroke range; the first rotating shaft group 20 rotates in the same direction as the handle 60, and the two ends of the shifting member 41 are pressed against the first rotating shaft group 20 and the second rotating shaft group 30 in the same direction of rotation, so that the shifting member 41 can push the second rotating shaft group 30 to rotate under the torque of the first rotating shaft group 20, so that the second rotating shaft group 30 rotates synchronously with the first rotating shaft group 20 through the shifting member 41, and the lock body performs the locking action to achieve locking.

[0048] When forcibly unlocking, the handle 60 is turned downwards, and the rotation stroke of the handle 60 easily exceeds the unlocking stroke range. The first pivot assembly 20 rotates with the handle 60, and the rotation direction of the first pivot assembly 20 is opposite to the direction when locking. The rotating part 41 is easily pushed up by the second pivot assembly 30 in this opposite rotation direction, causing the rotating part 41 to deflect. The two ends of the rotating part 41 separate from the first pivot assembly 20 and the second pivot assembly 30 respectively, thereby causing the second pivot assembly 30 to disengage from the rotating part 41. The first pivot assembly 20 spins freely, and the second pivot assembly 30 does not rotate. The torque of the first pivot assembly 20 is not transmitted to the second pivot assembly 30, and the unlocking fails. Moreover, the lock body is not subjected to excessive torque from the first pivot assembly 20, and the lock body is not damaged. The lock body is intact and does not need to be replaced due to forced unlocking, thus extending the service life of the lock body.

[0049] Compared to existing methods that use reinforced lock bodies or added anti-pry sensors, this utility model installs a rotary component 41 on the first rotating shaft assembly 20, which achieves the purpose of preventing forced entry of the smart door lock 101 without damaging the lock body. It has high security performance, low protection cost, and is easy to install.

[0050] Furthermore, since telescopic components often require springs to extend and retract, and springs lose elasticity over time, this can prevent them from performing normal extension and retraction, causing the lock to malfunction in both locking and unlocking, thus affecting the normal operation of the smart lock 101. In contrast, the movable component 40 uses a toggle mechanism 41, which eliminates the need for a spring to drive its rotation. This ensures proper locking while preventing forced entry of the smart lock 101; it also avoids the situation where a telescopic component 40 fails to perform normal extension and retraction, leading to locking failure.

[0051] Among them, the shifting component 41 can be a lever, a paddle, a cam, or a dial, etc.

[0052] In some embodiments, the movable structural member 40 is further provided with a driving member 42, which is disposed on the first rotating shaft assembly 20. The deflecting member 41 is provided with a rotation fulcrum 413 rotatably connected to the first rotating shaft assembly 20; the deflecting member 41 has a main body 414, a first end 411 located on one side of the main body 414 and a second end 412 on the opposite side, the first end 411 extends to a position adjacent to the driving member 42 and forms a first force-bearing arm that is abutted and exerted force by the driving member 42; the second end 412 extends to a position adjacent to the second rotating shaft assembly 30 and forms a second output force-bearing arm that pushes the second rotating shaft assembly 30.

[0053] The movable structural member 40 is configured such that when the rotation stroke of the handle 60 is within the locking stroke range, the drive member 42 rotates with the first rotating shaft group 20 to act on the first end 411, and the second end 412 abuts against the second rotating shaft group 30 to push the second rotating shaft group 30 to rotate; when the rotation stroke of the handle 60 exceeds the unlocking stroke range, the second end 412 is pushed by the second rotating shaft group 30 and deflects around the rotation fulcrum 413, the first end 411 disengages from the drive member 42, and the rotating member 41 slides relative to the second rotating shaft group 30, so that the first rotating shaft group 20 rotates freely relative to the second rotating shaft group 30.

[0054] In one embodiment, please refer to Figure 3 The rotating element 41 has a pivot point 413, which is rotatably connected to the first rotating shaft group 20. When locking, the first end 411 of the rotating element 41 is pressed against the driving element 42 on the first rotating shaft group 20, and the second end 412 abuts against the second rotating shaft group 30. At this time, the rotating element 41 is similar to a lever. The force of the driving element 42 on the rotating element 41 and the force of the second rotating shaft group 30 on the rotating element 41 resist each other, so that the rotating element 41 and the second rotating shaft group 30 are pressed tightly together. The rotating element 41 applies the torque of the first rotating shaft group 20 to the second rotating shaft group 30 to push the second rotating shaft group 30 to rotate, so that the second rotating shaft group 30 rotates synchronously with the first rotating shaft group 20 through the rotating element 41. The second rotating shaft group 30 transmits power to the lock body, and the lock body performs the locking action.

[0055] When forced unlocking occurs, the rotating member 41 rotates with the first rotating shaft group 20. The second end 412 of the rotating member 41 is deflected by the push of the second rotating shaft group 30, and the first end 411 of the rotating member 41 also disengages from the driving member 42 on the first rotating shaft group 20. At this time, the rotating member 41 slides relative to the second rotating shaft group 30, and the torque of the first rotating shaft group 20 cannot be transmitted to the second rotating shaft group 30 through the rotating member 41. The first rotating shaft group 20 rotates freely relative to the second rotating shaft group 30, the second rotating shaft group 30 does not rotate, and the lock body that is connected to the second rotating shaft group 30 does not rotate, so forced unlocking fails.

[0056] Optionally, two push blocks 12 can be provided protruding from the outer periphery of the second rotating shaft assembly 30. When locking, the rotating member 41 abuts against one of the push blocks 12, causing the rotating member 41 to move in conjunction with the second rotating shaft assembly 30, thus pushing the second rotating shaft assembly 30 to rotate. However, when forcibly unlocking, the rotating member 41 is pushed by the other push block 12, causing the rotating member 41 to slide relative to the second rotating shaft assembly 30. The torque of the first rotating shaft assembly 20 cannot be transmitted to the second rotating shaft assembly 30 through the rotating member 41.

[0057] A groove may also be recessed on the outer periphery of the second pivot assembly 30. When locking, the rotating part 41 abuts against one of the inner walls of the groove to push the second pivot assembly 30 to rotate; when unlocking by force, the rotating part 41 is pushed against the other inner wall of the groove, and the rotating part 41 slides relative to the second pivot assembly 30.

[0058] Optionally, the drive component 42 can be a protruding post on the first shaft assembly 20, or a screw installed on the first shaft assembly 20.

[0059] By simply installing the drive component 42 on the first rotating shaft group 20, the rotating component 41 can be made to abut against the second rotating shaft group 30. The structure is simple and saves space. There is no need to install a spring to drive the rotating component 41, so as to avoid the situation where the spring force fails and the rotating component 41 cannot be driven.

[0060] In one embodiment, the rotating member 41 is a dial wheel, and the first end 411 is provided with a deflection hole 410 to limit the deflection range of the dial wheel; the driving member 42 is positioned in the deflection hole 410 and in the deflection path of the first end 411, so as to act on the first end 411 when the rotation stroke of the handle 60 is within the locking stroke range.

[0061] The drive component 42 is equipped with a convex cap structure. A deflection hole 410 is provided on the dial, and the drive component 42 is positioned within the deflection hole 410. This not only restricts the deflection direction and range of the dial component 41, but also prevents the dial component 41 from becoming misaligned when deflecting on the first rotating shaft group 20, thus preventing it from engaging with or being pushed by the second rotating shaft group 30. The convex cap structure on the drive component 42 also prevents the dial component 41 from detaching from the first rotating shaft group 20.

[0062] Furthermore, the deflection hole 410 is designed to be arc-shaped. The center of the arc-shaped deflection hole 410 is designed to be concentric or coincide with the rotation fulcrum 413, so that the dial can rotate around the rotation fulcrum 413.

[0063] In one embodiment, the radius of the arc-shaped deflection hole 410 is matched with the motion trajectory, so that when the drive member 42 moves in a circular motion with the first rotating shaft assembly 20, the contact between the drive member 42 and the deflection hole 410 is always tangential, so as to transmit torque to the dial wheel through friction, reducing the problem of the drive member 42 hitting the straight end edge and then getting stuck, thereby ensuring the continuous rotation of the dial wheel. In addition, the rounded corner design of the deflection hole 410 can make the stress distribution of the edge of the deflection hole 410 uniform, preventing the edge of the deflection hole 410 from breaking due to stress concentration.

[0064] The outer contour of the first end 411 of the dial is also arc-shaped to fit the disc-shaped base 21 of the first rotating shaft assembly 20, thereby ensuring that the first end 411 will not mechanically interfere with the edge or surface of the base 21 during the rotation of the dial on the base 21 of the first rotating shaft assembly 20. Furthermore, when the dial rotates to the push block 12, it can smoothly slide over it without easily interfering with the edge or surface of the push block 12.

[0065] For details, please refer to 2 and Figure 6 The deflection hole 410 of the dial is shaped to match the movement trajectory of the drive member 42, and the outer contour of the first end 411 is also shaped to match the movement trajectory of the drive member 42, so that when the dial rotates 180 degrees from the left side of the first shaft group 20 to the right side of the first shaft group 20, the first end 411 can still maintain contact with the drive member 42, and the dial can also realize the function of torque transmission.

[0066] In one embodiment, please refer to Figure 3 and Figure 4 The second rotating shaft assembly 30 includes a shaft body 31 and a circumferential limiting groove 32 provided on the shaft body 31. The limiting groove 32 has two opposing side baffles 33. The second end 412 abuts against one of the side baffles 33 and is driven to rotate by the pushing action of the driving member 42. Alternatively, the second end 412 is pushed by the other side baffle 33 and deflects around the rotation fulcrum 413, causing the second end 412 to disengage from the limiting groove 32 and slide relative to the second rotating shaft assembly 30.

[0067] In one embodiment, a limiting groove 32 is provided in the circumferential direction of the shaft body 31 to ensure that it abuts or pushes against the rotating member 41 while reducing the number of protrusions that would hinder the rotation of the first rotating shaft assembly 20.

[0068] In one embodiment, the curvature of the limiting groove 32 can be set to 90 degrees so that when the handle 60 is forcibly unlocked, the rotation stroke exceeds the 90-degree unlocking stroke range from the flat state to the vertical downward. Under the pushing action of the side wall 33 of the limiting groove 32, the rotating member 41 deflects and slides relative to the second rotating shaft group 30, so that the handle 60 cannot drive the second rotating shaft group 30 to rotate, thereby achieving anti-forced opening.

[0069] Among them, reference Figure 1 When the handle 60 is not lifted or turned down, the rotating member 41 is held against the drive member 42; and by using gravity, the rotating member 41 can abut against the side wall 33 of the limiting groove 32 of the second rotating shaft group 30, so that the action of pushing the second rotating shaft group 30 can be realized more quickly when locking.

[0070] Please refer to Figure 4The second rotating shaft assembly 30 has a protruding ring structure 34 on its outer periphery. The protruding ring structure 34 avoids the limiting groove 32. This not only ensures that the rotating part 41 does not disengage from the side wall 33 due to the torque of the first rotating shaft assembly 20 when locking, but also pushes the second end 412 of the rotating part 41 out of the limiting groove 32 when forcibly unlocking, so that the rotating part 41 is in a deflected and sliding state relative to the second rotating shaft assembly 30, thereby ensuring that the torque of the first rotating shaft assembly 20 is not transmitted to the second rotating shaft assembly 30.

[0071] In some embodiments, the first pivot assembly 20 includes a base 21 and a shaft 22, the shaft 22 being connected to the handle 60, the base 21 being located at the end of the shaft 22 away from the handle 60, and the base 21 being provided with a receiving groove 210 for the deflection movement of the dial wheel.

[0072] In one embodiment, please refer to Figure 7 The shaft portion 22 of the first rotating shaft assembly 20 is connected to the handle 60 via a fixing member 23. The deflector 41 is rotatably mounted on the first rotating shaft assembly 20, and the deflector 41 deflects within the receiving groove 210 of the seat 21, so as to limit the deflection range of the entire deflector 41 while saving space.

[0073] A cover plate 80 can be installed on the base 21 to further prevent the rotating part 41 from dislodging from the receiving groove 210 and to prevent the rotating part 41 from becoming skewed, which would cause it to fail to abut against the second rotating shaft assembly 30 or the drive part 42.

[0074] Since the Smart Lock 101 needs to support both left and right opening to adapt to different installation environments and opening habits, please refer to [link / reference needed]. Figure 1 and Figure 6 There are two receiving slots 210, which are mirror images of each other along the central axis of the base 21; there are two second ends 412, which are mirror images of each other along the deflection center axis of the rotating member 41.

[0075] The second pivot assembly 30 can be manually rotated to the other side. The rotating part 41 can abut against or be pushed by the second pivot assembly 30 on either the left or right side of the first pivot assembly 20, thereby ensuring that the smart door lock 101 can be unlocked, locked, and protected against forced unlocking even when the handle 60 is installed on different sides.

[0076] In one embodiment, reference is made to Figure 3 and Figure 6 The limiting groove 32 has a first side baffle 331 and a second side baffle 332. (Refer to...) Figure 3 When the second rotating shaft assembly 30 and the deflector 41 are located on the left side, the deflector 41, under the action of gravity, causes its second end 412 to abut against the first side wall 331. (Refer to...) Figure 6The second rotating shaft group 30 is manually rotated to the right, and the rotating part 41 is located on the right. Under the action of gravity, the other second end 412 of the rotating part 41 hangs down to abut against the second side wall 332.

[0077] The rotating component 41 can abut against or slide relative to the second rotating shaft group 30 on either the left or right side, thereby ensuring that the smart door lock 101 can complete the unlocking, locking, and anti-forced unlocking operations on different sides.

[0078] Please see Figure 2 The anti-violent unlocking structure 100 also includes a drive device 11, a push block 12, and a telescopic pin 50. The output end of the drive device 11 is connected to the push block 12 to drive the push block 12 to move. The first rotating shaft assembly 20 is provided with a first connecting groove 211, and the second rotating shaft assembly 30 is provided with a second connecting groove 310 corresponding to the first connecting groove 211. The telescopic pin 50 is provided in the first connecting groove 211. The telescopic pin 50 is pushed by the push block 12 and extends into the second connecting groove 310 to connect the first rotating shaft assembly 20 and the second rotating shaft assembly 30; or the telescopic pin 50 extends out from the second connecting groove 310.

[0079] During normal unlocking, a password or key must first be entered. Then, the drive device 11 responds and the drive pusher 12 extends to push the telescopic pin 50 into the second connecting groove 310, connecting the first rotating shaft assembly 20 to the second rotating shaft assembly 30 via the telescopic pin 50. The second rotating shaft assembly 30 then drives the lock body, causing the lock body to unlock. The methods of entering a password or key and the drive device 11 responding and starting operation are existing technologies and will not be described in detail here.

[0080] In some embodiments, a reset member 212 is installed in the first connecting groove 211. The reset member 212 is used to reset the telescopic pin 50, which extends into the second connecting groove 310, in a direction away from the second rotating shaft assembly 30. After normal unlocking, the reset member 212 resets the telescopic pin 50 back into the first connecting groove 211, facilitating subsequent locking via the movable structural member 40 and preventing forced unlocking. It also prevents the lock body from performing an unlocking action due to the telescopic pin 50's linkage with the first and second rotating shaft assemblies 20 and 30 during forced unlocking.

[0081] In one embodiment, the reset member 212 is a spring.

[0082] Since the handle 60 sometimes needs to be used in reverse, the second rotating shaft group 30 is manually rotated from the left to the right, and the second connecting groove 310 is also driven to rotate a certain angle.

[0083] Therefore, to ensure that the telescopic pin 50 extends into the second connecting groove 310 to connect the first rotating shaft assembly 20 and the second rotating shaft assembly 30 during normal unlocking, please refer to [link to relevant documentation]. Figure 8 There are two second connecting slots 310. The two second connecting slots 310 are set at an angle to each other so that when the second rotating shaft assembly 30 is manually rotated from the left to the right, there is still one second connecting slot 310 corresponding to the first connecting slot 211. This allows the telescopic pin 50 to be driven by the push block 12 and extend into the second connecting slot 310, thus ensuring that the first rotating shaft assembly 20 is connected to the second rotating shaft assembly 30 through the telescopic pin 50, thereby ensuring normal unlocking.

[0084] Furthermore, in one embodiment, the first side baffle 331 and the second side baffle 332 of the second rotating shaft assembly 30 are mirror images of each other with respect to the central axis of the second rotating shaft assembly 30. When rotating the second rotating shaft assembly 30 from the left to the right, it is only necessary to rotate the second rotating shaft assembly 30 by 90 degrees, so that the second end 412 of the rotating member 41 can be received by the second side baffle 332.

[0085] Therefore, in one embodiment, the two second connecting grooves 310 are arranged perpendicularly to each other, one of the second connecting grooves 310 is arranged corresponding to the first connecting groove 211, and the other second connecting groove 310 is arranged opposite to the slotting direction of the limiting groove 32. In this way, when the second rotating shaft assembly 30 is rotated 90 degrees from the left to the right, one of the second connecting grooves 310 also rotates to the position corresponding to the first connecting groove 211, thereby ensuring that the telescopic pin 50 can be inserted into the second rotating shaft assembly 30 to connect with the second rotating shaft.

[0086] After a forced unlocking attempt fails, the lock body remains undamaged. For normal use in the future, the handle 60 is turned directly in the locking direction to drive the first rotating shaft group 20 to rotate. This causes the rotating part 41 to rotate with the first rotating shaft group 20 and fall back into the limiting groove 32 of the second rotating shaft group 30, thereby restoring the anti-forced unlocking structure 100 to the state before forced unlocking.

[0087] In another embodiment, to reverse the use of handle 60, please refer to... Figure 5 , Figure 1 and Figure 6 First, the drive component 42 needs to be removed to prevent the rotating component 41 from affecting the rotation of the first rotating shaft group 20; then, manually rotate the second rotating shaft group 30 to the right; then, rotate the handle 60 to the left, the first rotating shaft group 20 rotates and drives the rotating component 41 to rotate; when the second end 412 of the rotating component 41 abuts against the side wall 33 of the second limiting groove 32 under the action of gravity, the drive component 42 can be reinstalled.

[0088] This utility model also proposes an intelligent door lock 101, please refer to [link / reference]. Figure 7 and Figure 9The smart door lock 101 includes a handle 60, a lock body, a faceplate 70, and an anti-violent unlocking structure 100. The specific structure of the anti-violent unlocking structure 100 is as described in the above embodiments. Since the smart door lock 101 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. Among them, the first rotating shaft group 20 is rotatably installed on the side of the faceplate 70 facing the lock body, the handle 60 is installed on the other side of the faceplate 70 and connected to the first rotating shaft group 20, and the lock body is drivenly connected to the second rotating shaft group 30; a limiting space 71 is provided on the side of the faceplate 70 facing the first rotating shaft group 20, and the first rotating shaft group 20 rotates in the limiting space 71.

[0089] Please refer to Figure 9 The first rotating shaft assembly 20 has a torsion spring 72 and a cylinder installed on the side facing the face shell 70, which is existing technology and will not be described in detail here.
