Description

Technical Field

[0001] This application belongs to the field of intelligent door lock technology, and particularly relates to a door lock and door assembly. Background Technology

[0002] With social development, more and more families are adopting smart door locks. Smart door locks can recognize facial recognition, fingerprint recognition, password recognition, and other permissions. Once recognition is successful, users can unlock the door by turning the handle. Compared with traditional door locks, smart door locks are more convenient and faster, and their security and reliability are greatly improved.

[0003] In related technologies, when a smart lock successfully identifies a user, a drive mechanism drives a connector to fix the handle and lock body together. The user can then turn the handle to turn the lock body and unlock the door. However, this method has a security risk: if a thief repeatedly strikes the smart lock with a hammer, the resulting vibration could also drive the connector to fix the handle and lock body together, allowing the thief to open the door even if the lock is not successfully identified, resulting in poor door lock security. Summary of the Invention

[0004] This application aims to at least partially solve the technical problem of poor door lock security. To this end, this application provides a door lock and a door assembly.

[0005] In a first aspect, embodiments of this application provide a door lock, the door lock including a front panel mechanism, a verification mechanism, and a lock body, wherein a portion of the lock body is installed within the front panel mechanism, and the verification mechanism is installed on the outer surface of the front panel mechanism; the front panel mechanism includes:

[0006] Front housing, with mounting cavity;

[0007] The handle assembly and the free assembly are provided, with at least a portion of the handle assembly located outside the mounting cavity, and the free assembly disposed inside the mounting cavity and fixedly connected to the pivot of the lock body, and the free assembly movably engaging with the handle assembly.

[0008] A first connecting component is disposed within the mounting cavity;

[0009] A driving component and a second connecting component are disposed within the mounting cavity. If the verification mechanism successfully verifies the connection, the driving component drives the second connecting component to fix the free component and the handle component.

[0010] Wherein, when the front housing is subjected to external force, the first connecting assembly can fixably connect the free assembly and the front housing.

[0011] In the door lock proposed in this application embodiment, the front housing is fixedly installed on the door body. Since the first connecting component can fix the free component and the front housing when the front housing is subjected to external force, the free component cannot rotate under the restriction of the front housing, and the pivot of the lock body cannot rotate either. This solves the problem of thieves unlocking the door by hitting the front housing to a certain extent, and improves the security of the door lock.

[0012] In some embodiments, the free assembly has a first cavity in which the first connecting assembly is installed; wherein, when the front housing is subjected to an external force, the first connecting assembly can extend out of the first cavity and be fixedly connected to the front housing.

[0013] In some embodiments, the inner wall of the mounting cavity is provided with a first card interface corresponding to the first cavity, and the first connecting component can engage with the first card interface when it extends out of the first cavity.

[0014] In some embodiments, the first connecting assembly includes a first clutch pin and a first elastic member. The end of the first clutch pin is provided with a first limiting portion. One end of the first elastic member abuts against the first limiting portion, and the other end abuts against the inner wall of the first cavity. The first elastic member is used to provide an elastic force to the first clutch pin to disengage from the first card interface.

[0015] In some embodiments, the free assembly further has a shaft hole and a second cavity, the rotating shaft is fitted into the shaft hole, the first cavity and the second cavity are respectively disposed on both sides of the shaft hole, and the second connecting assembly is installed in the second cavity; if the verification mechanism verifies successfully, the driving assembly drives the second connecting assembly to extend out of the second cavity and be fixedly connected to the handle assembly.

[0016] In some embodiments, the handle assembly includes a handle member and a reversing member fixedly connected, the handle member being disposed outside the mounting cavity, and the reversing member being disposed inside the mounting cavity and movably cooperating with the free component.

[0017] In some embodiments, the free component has a second cavity, in which the second connecting component is installed; the commutator has an axis of symmetry, and the commutator is provided with a second card interface and a third card interface symmetrically arranged along the axis of symmetry, the second card interface communicating with the second cavity; when the verification mechanism verifies successfully, the driving component drives the second connecting component to extend out of the second cavity and engage with the second card interface.

[0018] In some embodiments, the lock body is locked when the pivot rotates from its initial state along a first direction, and unlocked when the pivot rotates from its initial state along a second direction, wherein the first direction and the second direction are opposite; and when the handle assembly rotates along the first direction, the reversing member can push the free assembly to rotate along the first direction.

[0019] In some embodiments, the commutator includes a commutation portion and a protrusion disposed on the commutation portion, the protrusion being able to abut against the free assembly to push the free assembly to rotate in a second direction.

[0020] In some embodiments, the commutator has an axis of symmetry, the protrusion includes a first protruding segment and a second protruding segment symmetrically arranged along the axis of symmetry, the free segment has a first free segment and a second free segment, the first protruding segment and the first free segment are correspondingly arranged and spaced apart from each other, and the second protruding segment and the second free segment are correspondingly arranged and abut against each other.

[0021] In some embodiments, the door lock further includes a reset member disposed within the mounting cavity, which can reset the commutator to the initial state when the commutator rotates from its initial state.

[0022] In some embodiments, the reset member includes an elastic portion and a first pin portion and a second pin portion disposed at both ends of the elastic portion, the elastic portion being connected to the inner wall of the mounting cavity; the inner wall of the mounting cavity has a first overlapping member and a second overlapping member; the reversing member includes a reversing portion and a first pushing portion and a second pushing portion disposed on the reversing portion; the first pin portion overlaps with the first overlapping member and the first pushing portion, and the second pin portion overlaps with the second overlapping member and the second pushing portion.

[0023] In some embodiments, one of the first and second pushing parts is detachably connected to the reversing part.

[0024] In some embodiments, the inner wall of the mounting cavity is further provided with a first stop and a second stop. The first stop is disposed near the first pin portion to stop the first pushing portion; the second stop is disposed near the second pin portion to stop the second pushing portion.

[0025] Secondly, this application provides a door assembly, including a door body and the door lock described above, wherein the front panel mechanism is disposed on the side of the door body, and a portion of the lock body is installed inside the door body.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0047] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0048] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0049] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0050] With social development, more and more families are adopting smart door locks. Smart door locks can recognize facial recognition, fingerprint recognition, password recognition, and other permissions. Once recognition is successful, users can unlock the door by turning the handle. Compared with traditional door locks, smart door locks are more convenient and faster, and their security and reliability are greatly improved.

[0051] In related technologies, after a smart lock successfully identifies its user, a drive component drives a connector to fix the handle and lock body together. The user can then turn the handle to rotate the lock body and unlock the door. However, this method has a security vulnerability: a thief could repeatedly strike the smart lock with a hammer, and the resulting vibrations could also drive the connector to fix the handle and lock body together, allowing the thief to open the door even without successful identification, resulting in poor lock security. The door lock and door assembly provided in this application can, to some extent, improve the situation where a thief can unlock the door by striking the front housing, thus enhancing the lock's security.

[0052] This application is described below with reference to the accompanying drawings and specific embodiments:

[0053] Please see Figure 1 and Figure 2 This application provides a door lock 10, which is applied to a door 20 in a building. The building has an interior space and a doorway communicating with the interior space. The door 20 is installed at the doorway and hinged to the building on one side to open or close the interior space. The door lock 10 provided in this application can, to some extent, improve the security of the door lock 10 by preventing thieves from unlocking it by striking the front housing 110.

[0054] The door body 20 is roughly a cuboid. For ease of description, we define the height direction Z, width direction X, and thickness direction Y. In the usable state of the door body 20, the vertical direction is the height direction Z, and the projection of the door body 20 in the vertical direction is a rectangle. The direction of the longer side is the width direction X, and the direction of the shorter side is the thickness direction Y.

[0055] Similarly, for ease of description, six directions are defined: up, down, left, right, front, and back. In the height direction Z, the side closer to the top is up, and the side closer to the bottom is down. In the width direction X, the two directions are left and right, with the side where the door 20 is hinged to the building being right and the opposite side being left. In the thickness direction Y, the side of the door 20 closer to the interior space is back (inside), and the opposite side is front (outside).

[0056] Please see Figures 3-5In this embodiment, the door lock 10 includes a front panel mechanism 100, a verification mechanism 200, and a lock body 300. A portion of the lock body 300 is installed within the front panel mechanism 100, and the verification mechanism 200 is installed on the outer surface of the front panel mechanism 100. The front panel mechanism 100 includes a front housing 110, a handle assembly 120, a free-moving assembly 130, a first connecting assembly 140, a drive assembly 150, and a second connecting assembly 160. The front housing 110 has a mounting cavity 113, at least part of the handle assembly 120 is located outside the mounting cavity 113, the free assembly 130 is disposed inside the mounting cavity 113 and fixedly connected to the pivot 310 of the lock body 300, and the free assembly 130 is movably engaged with the handle assembly 120; the first connecting assembly 140 is disposed inside the mounting cavity 113; the drive assembly 150 and the second connecting assembly 160 are disposed inside the mounting cavity 113. When the verification mechanism 200 verifies successfully, the drive assembly 150 drives the second connecting assembly 160 to fixally connect the free assembly 130 and the handle assembly 120.

[0057] When the front housing 110 is subjected to external force, the first connecting component 140 can fix the free component 130 and the front housing 110.

[0058] The front panel mechanism 100 is located on the front side of the door 20. When a user needs to enter the interior space from the outside, they unlock the door 20 through the front panel mechanism 100. The verification mechanism 200 is used to verify user permissions. It can verify user permissions through methods such as face, fingerprint, and password. When the verification mechanism 200 verifies that the face, fingerprint, or password matches the preset version, the verification is successful, and the user can unlock the door through the front panel mechanism 100. The lock body 300 includes a pivot 310 and a bolt 320. The bolt 320 is located inside the door 20. The pivot 310 can drive the bolt 320 to extend or retract by rotating, thereby locking or unlocking the lock body 300.

[0059] The front housing 110 is fixedly connected to the door body 20 to enable the installation of the front panel mechanism 100 on the door body 20. The front housing 110 is the basic component of the front panel mechanism 100, providing a mounting base for other structures within the front panel mechanism 100. Structures such as the verification mechanism 200 can be installed on the front housing 110, allowing the front panel mechanism 100 to form a unified whole, facilitating its installation and transportation. Simultaneously, the front housing 110 also provides protection for other structures within the front panel mechanism 100.

[0060] At least a portion of the handle assembly 120 is located outside the mounting cavity 113 to facilitate the user's rotation of the handle assembly 120 to lock or unlock. Since the right side of the door 20 is hinged to the building, the front housing 110 may be located on the left side of the door 20 to facilitate the user's movement of the door 20 by gripping the handle assembly 120, so that the handle assembly 120 is located on the left side of the door 20.

[0061] The free-moving component 130 is disposed in the mounting cavity 113 and fixedly connected to the rotating shaft 310 of the lock body 300. The free-moving component 130 is movably engaged with the handle assembly 120. That is, under normal circumstances, the free-moving component 130 and the handle assembly 120 are connected but not fixedly connected. The free-moving component 130 and the handle assembly 120 can rotate relative to each other. Therefore, even if the handle assembly 120 is rotated, the free-moving component 130 cannot be driven to rotate, and thus the rotating shaft 310 of the lock body 300 cannot be driven to rotate, so the locking or unlocking cannot be achieved.

[0062] If the verification by the verification mechanism 200 is successful, the drive component 150 drives the second connection component 160 to fix the free component 130 and the handle component 120 together, making the free component 130 and the handle component 120 a whole. At this time, when the user turns the handle component 120, the free component 130 drives the rotating shaft 310 to rotate, causing the bolt 320 to retract and unlocking.

[0063] If the verification mechanism 200 fails to verify, the drive assembly 150 will not drive the second connecting assembly 160 to fix the free assembly 130 and the handle assembly 120. However, if the front housing 110 is subjected to external force, the second connecting assembly 160 may still fix the free assembly 130 and the handle assembly 120 under the drive of the external force. Please refer to... Figure 5 Because the first connecting component 140 can also fixably connect the free component 130 and the front housing 110 when the front housing 110 is subjected to external force, that is, while the second connecting component 160 fixes the free component 130 and the handle component 120 under the action of external force, the first connecting component 140 also fixes the free component 130 and the front housing 110. In other words, the free component 130, the handle component 120 and the front housing 110 form a whole, and the front housing 110 is fixedly connected to the door body 20. Since the door body 20 is fixed, the free component 130 and the handle component 120 cannot rotate, thus making it impossible to unlock. That is, the door lock 10 provided in this application embodiment is difficult to unlock even if a thief strikes the front housing 110 with a hammer, thereby greatly improving the security of the door lock 10.

[0064] It should be noted that, if the verification by the verification mechanism 200 is successful, the second connecting component 160 is fixedly connected to the free component 130 and the handle component 120 by the driving force of the driving component 150. Therefore, when a thief attempts to unlock the lock, he will strike the front housing 110 with a hammer to simulate the driving force of the driving component 150. That is, the "external force" mentioned in this embodiment refers to the striking force generated by the thief when simulating the driving force of the driving component 150, and this striking force is in the same direction as the driving force of the driving component 150.

[0065] Of course, the door lock 10 also includes a rear panel mechanism 400, which is located on the rear side of the door 20. When a user needs to exit from the interior space, the door 20 is unlocked through the rear panel mechanism 400. However, since no verification is required for the user to exit from the interior space, there is no need to set up a verification mechanism 200 on the rear panel mechanism 400, and therefore no need to set up a free-floating component 130. The handle of the rear panel mechanism 400 is directly connected to the pivot 310 of the lock body 300, and the lock can be unlocked directly by turning the handle. That is, the improvements to the lock body 300 in this embodiment are all aimed at the front panel mechanism 100, and the rear panel mechanism 400 can adopt any design scheme in the prior art, which will not be described in detail here.

[0066] Please see Figures 6-8 In some embodiments, the free assembly 130 has a first cavity 133 and a first connecting assembly 140 is installed in the first cavity 133; wherein, when the front housing 110 is subjected to an external force, the first connecting assembly 140 can extend out of the first cavity 133 and be fixedly connected to the front housing 110.

[0067] That is, the free component 130 is the mounting component of the first connecting component 140, and the first connecting component 140 is movably disposed within the first cavity 133. Please refer to [link / reference]. Figure 7 In normal conditions, the first connecting assembly 140 is installed in the first cavity 133 and is separated from the front housing 110. However, when the front housing 110 is subjected to external force, please refer to [the relevant documentation]. Figure 8 The first connecting component 140 will extend out of the first cavity 133 and be fixedly connected to the front housing 110 under the action of external force. Of course, only part of the first connecting component 140 extends out of the first cavity 133 and is fixedly connected to the front housing 110, while the other part is still installed in the first cavity 133, thereby realizing the fixed connection between the free component 130 and the front housing 110.

[0068] In some embodiments, the free assembly 130 also has a shaft hole 135 and a second cavity 134. The rotating shaft 310 is fitted into the shaft hole 135. The first cavity 133 and the second cavity 134 are respectively disposed on both sides of the shaft hole 135. The second connecting assembly 160 is installed in the second cavity 134. When the verification mechanism 200 verifies successfully, the drive assembly 150 drives the second connecting assembly 160 to extend out of the second cavity 134 and be fixedly connected to the handle assembly 120.

[0069] The rotating shaft 310 is fitted into the shaft hole 135 to achieve a fixed connection between the free assembly 130 and the rotating shaft 310. (See also...) Figure 7 Under normal conditions, the second connecting assembly 160 is installed in the second cavity 134 and is separated from the handle assembly 120. However, when the verification mechanism 200 successfully verifies the connection, please refer to [the relevant documentation]. Figure 8 The drive component 150 then drives the second connecting component 160 to extend out of the second cavity 134 and be fixedly connected to the handle assembly 120. Of course, only part of the second connecting component 160 extends out of the second cavity 134 and is fixedly connected to the handle assembly 120, while the other part remains installed in the second cavity 134, thereby achieving a fixed connection between the free component 130 and the handle assembly 120.

[0070] Specifically, the first cavity 133 may be located above the shaft hole 135, the second cavity 134 may be located below the shaft hole 135, the first connecting assembly 140 extends upward from the first cavity 133 to be fixedly connected to the front housing 110, the second connecting assembly 160 extends upward from the second cavity 134 to be fixedly connected to the handle assembly 120, and the driving assembly 150 is disposed below the free assembly 130 to drive the second connecting assembly 160 to extend upward.

[0071] If the verification mechanism 200 fails to verify, the thief can use a hammer to repeatedly and quickly strike the bottom of the front housing 110 from bottom to top. At the moment of the strike, the second connecting component 160 will extend upward instantly under the impact of the impact to fix it to the handle component 120, so that the free mechanism and the handle component 120 are linked. However, at the same time, the first connecting component 140 will also extend upward instantly under the impact of the impact to connect to the front housing 110. As a result, the free component 130 and the handle component 120 cannot rotate, and thus cannot unlock.

[0072] In some embodiments, the inner wall of the mounting cavity 113 is provided with a first card interface 114 corresponding to the first cavity 133, and the first connecting component 140 can engage with the first card interface 114 when it extends out of the first cavity 133.

[0073] Since the first card interface 114 is correspondingly set with the first cavity 133, the first connecting component 140 can be snapped into the first card interface 114 after extending out of the first cavity 133, thereby realizing the fixed connection between the free component 130 and the handle component 120.

[0074] Please see Figure 9 and Figure 10 In some embodiments, the first connecting assembly 140 includes a first clutch pin 141 and a first elastic member 142. The end of the first clutch pin 141 is provided with a first limiting portion 143. One end of the first elastic member 142 abuts against the first limiting portion 143, and the other end abuts against the inner wall of the first cavity 133. The first elastic member 142 is used to provide an elastic force to the first clutch pin 141 to disengage from the first card interface 114.

[0075] The inner wall of the first cavity 133 is the inner wall of the upper side of the first cavity 133, and the first limiting part 143 is disposed at the lower end of the first elastic member 142. When the thief knocks on the front housing 110, the upward vibration force on the first clutch pin 141 will counteract the elastic force of the first elastic member 142 and the weight of the first clutch pin 141 itself, causing the first clutch pin 141 to extend upward from the first cavity 133, that is, the first limiting part 143 moves towards the inner wall of the upper side of the first cavity 133. During this process, the first elastic member 142 will be compressed. Therefore, when the external force disappears, the first elastic member 142 will elastically release, which will drive the first clutch pin 141 to disengage from the first card interface 114 and return to the initial position.

[0076] Furthermore, the first limiting part 143 can abut against the inner wall on the upper side of the first cavity 133 to prevent the first clutch pin 141 from disengaging from the first cavity 133 during the upward extension process as much as possible.

[0077] Understandably, when the verification structure is successfully verified, the drive component 150 drives the second connecting component 160 to extend upwards, allowing the user to turn the handle component 120 to unlock. After the user completes the unlocking action, the second connecting component 160 will also return to its initial position, disconnecting the free component 130 from the handle component 120, preparing for the next unlocking verification. That is, even if the second connecting component 160 extends upwards under external force, it will return to its initial position when the external force disappears. Therefore, when the first clutch pin 141 disengages from the first card interface 114 and returns to its initial position, the second connecting component 160 will also return to its initial position. At this time, the free component 130 and the handle component 120 are disconnected, and the thief still cannot unlock the door.

[0078] Specifically, please refer to Figure 9 and Figure 10The second connecting assembly 160 includes a second clutch pin 161 and a second elastic member 162. The driving assembly 150 can be a clutch that cooperates with the second clutch pin 161. The outer surface of the second clutch pin 161 is provided with a second limiting portion 163. One end of the second elastic member 162 abuts against the second limiting portion 163, and the other end abuts against the inner wall of the upper side of the second cavity 134. When a thief strikes the front housing 110, the upward vibration force on the second clutch pin 161 will counteract the elastic force of the second elastic member 162 and the weight of the second clutch pin 161 itself, causing the second clutch pin 161 to extend upward from the second cavity 134. That is, the second limiting portion 163 moves towards the inner wall of the upper side of the second cavity 134. During this process, the second elastic member 162 is compressed. Therefore, when the external force disappears, the second elastic member 162 elastically releases, which will drive the second clutch pin 161 back to its initial position. Both the first elastic member 142 and the second elastic member 162 can be springs.

[0079] Of course, in order to avoid the unexpected situation where the first clutch pin 141 disengages from the first card interface 114 and returns to the initial position while the second clutch pin 161 has not yet returned to the initial position, a one-way damping structure can be provided on the first elastic member 142 to slow down the elongation process of the first elastic member 142, thereby extending the time for the first clutch pin 141 to return to the initial position.

[0080] Please see Figure 11 and Figure 12 In some embodiments, the handle assembly 120 includes a handle 121 and a reversing member 122 that are fixedly connected. The handle 121 is disposed outside the mounting cavity 113, and the reversing member 122 is disposed inside the mounting cavity 113 and is movably engaged with the free assembly 130.

[0081] The front housing 110 may include a front panel 111 and a front bottom plate 112, which form a mounting cavity 113. The front bottom plate 112 is fixedly connected to the door body 20. The free-floating assembly 130 may include a free-floating body 131 and a cover plate 132, which are connected to form a first cavity 133 and a second cavity 134. The cover plate 132 is fixedly connected to the inner wall of the mounting cavity 113.

[0082] The handle 121 is located outside the mounting cavity 113 for easy user operation. When the user rotates the handle 121, it drives the reversing component 122 to rotate. Since the reversing component 122 is in movable cooperation with the free assembly 130, the second connecting component 160 can fixably connect the reversing component 122 and the free assembly 130.

[0083] Specifically, please refer to Figure 13 and Figure 14A retaining flange 123 can be provided on the reversing component 122, and a mounting hole 138 can be provided on the free assembly 130. The retaining flange 123 is installed in the mounting hole 138 with a gap, so that the reversing component 122 and the free assembly 130 can be moved and fitted. The mounting hole 138 and the shaft hole 135 can be located on both sides of the free assembly 130, so that the rotating shaft 310 and the reversing component 122 do not interfere with each other. The mounting hole 138 and the shaft hole 135 can be coaxially arranged and connected.

[0084] In some embodiments, when the pivot 310 rotates from its initial state along a first direction, the lock body 300 is locked, and when the pivot 310 rotates from its initial state along a second direction, the lock body 300 is unlocked, with the first and second directions being opposite; when the handle 121 rotates along the first direction, the reversing member 122 can push the free assembly 130 to rotate along the first direction.

[0085] Of the first and second directions, one is clockwise and the other is counterclockwise. The initial state is when the pivot 310 is not rotating. When the pivot 310 rotates from the initial state along the first direction, the latch 320 extends, locking the lock body 300. When the pivot 310 rotates from the initial state along the second direction, the latch 320 retracts, unlocking the lock body 300. That is, when the user leaves and closes the door 20, they can rotate the handle 121 along the first direction, causing the pivot 310 to rotate in the same direction, thus locking the lock body 300. After successful verification, the user can rotate the handle 121 along the second direction, causing the pivot 310 to rotate in the same direction, thus unlocking the lock body 300. It should be noted that locking the lock body 300 here can be understood as deadbolting.

[0086] Once the verification structure is successfully verified, the second connecting component 160 can be fixedly connected to the reversing component 122 and the free component 130. Thus, rotating the handle component 121 in the second direction will drive the rotating shaft 310 to rotate in the second direction to unlock. When the user leaves and closes the door 20, although the reversing component 122 and the free component 130 are not directly connected, the reversing component 122 can push the free component 130 to rotate in the first direction when the user rotates the handle component 121 in the first direction. Therefore, it can also drive the rotating shaft 310 to rotate in the first direction to lock.

[0087] Please see Figure 12 and Figure 13 In some embodiments, the commutator 122 includes a commutator portion 1221 and a protrusion 1222 disposed on the commutator portion 1221. The protrusion 1222 can abut against the free assembly 130 to push the free assembly 130 to rotate in the second direction.

[0088] The protrusion 1222 protrudes from the outer surface of the reversing part 1221 and abuts against one side of the free assembly 130, so that when the reversing part 1221 rotates in the second direction, the protrusion 1222 can abut against the free assembly 130 to push the free assembly 130 to rotate in the second direction.

[0089] It should be emphasized that the protrusion 1222 is located on one side of the reversing part 1221 and only abuts against one side of the free assembly 130. This allows the protrusion 1222 to push the free assembly 130 to move only when the reversing part 1221 rotates in the second direction. When the reversing part 1221 moves in the first direction, the protrusion 1222 moves away from the free assembly 130 to prevent the protrusion 1222 from pushing the free assembly 130 to move in the first direction, thus causing the lock body 300 to unlock directly.

[0090] Please see Figures 13-15 In some embodiments, the commutator 122 has an axis of symmetry, and the protrusion 1222 includes a first protrusion segment 1222a and a second protrusion segment 1222b arranged symmetrically along the axis of symmetry. The free assembly 130 has a first free segment 136 and a second free segment 137. The first protrusion segment 1222a and the first free segment 136 are correspondingly arranged and spaced apart from each other, and the second protrusion segment 1222b and the second free segment 137 are correspondingly arranged and abut against each other.

[0091] The first cavity 133 is located in the first free section 136, and the second cavity 134 is located in the second free section 137. When installing the door lock 10 on-site, the installation direction of the handle 121 needs to be adjusted according to the actual opening direction of the user's door, such as whether it opens to the left or right. Generally, lifting the handle 121 locks the door, and pressing it down unlocks it. For ease of description, let's use... Figure 12 Taking the orientation as an example, the first direction is defined as clockwise and the second direction as counterclockwise. That is, raising the handle 121 (clockwise) locks the device, and pressing down the handle 121 (counterclockwise) unlocks it. Of course, in other embodiments, the first direction can be counterclockwise and the second direction can be clockwise; there is no limitation on this.

[0092] The axis of symmetry of the commutator 122 is set along the width direction X, that is, the upper and lower parts of the commutator 122 are symmetrical. Figure 12 Taking the orientation as an example, the protrusion 1222 is located on the right side of the reversing part 1221, and the right side of the free component 130 abuts against the protrusion 1222. Therefore, when the reversing part 122 rotates clockwise, the protrusion 1222 can push the free component 130 to rotate clockwise.

[0093] When the installation direction of the handle 121 needs to be adjusted, the reversing member 122 can be rotated 180° counterclockwise. During the rotation of the reversing member 122, since there is a gap between the first protruding segment 1222a and the first free segment 136, the first protruding segment 1222a will not push the free component 130 to rotate together. When the second protruding segment 1222b passes the first free segment 136, since the first protruding segment 1222a and the second protruding segment 1222b are symmetrically arranged, there is still a gap between the second protruding segment 1222b and the first free segment 136, so the second protruding segment 1222b will not push the free component 130 to rotate together. In other words, during the 180° counterclockwise rotation of the reversing member 122, the free component 130 remains stationary, thus not affecting the functions of the first connecting component 140 and the second connecting component 160.

[0094] When the direction of the handle 121 is reversed, lifting the handle 121 (counterclockwise) locks the mechanism, and pressing it down (clockwise) unlocks it. When the reversing member 122 rotates 180° counterclockwise, the protrusion 1222 changes from being located on the right side of the reversing member 1221 to being located on the left side of the reversing member 1221, and the left side of the free-electrode component 130 abuts against the protrusion 1222. In this way, when the handle 121 rotates counterclockwise, the protrusion 1222 can push the free-electrode component 130 to rotate counterclockwise to achieve locking, while when the handle 121 rotates clockwise, the protrusion 1222 moves away from the free-electrode component 130.

[0095] Therefore, when the installation direction of the handle 121 needs to be adjusted, simply rotate the reversing component 122 180° without adjusting the free assembly 130. During the 180° rotation of the reversing component 122, the function of the free assembly 130 is not affected, nor is the pushing function of the reversing component 122 on the free assembly 130 affected. The direction of the reversing component 122 can be adjusted according to actual needs, making the direction adjustment of the handle 121 more convenient and quick, saving operators' time.

[0096] Specifically, please refer to Figure 15 The first free segment 136 and the second free segment 137 can be staggered in the thickness direction Y, that is, the first free segment 136 is set close to the reversing member 122, and the second free segment 137 is set away from the reversing member 122 relative to the first free segment 136, so that the first free segment 136 abuts against the first protruding segment 1222a, and there is a gap between the second free segment 137 and the second protruding segment 1222b.

[0097] Please see Figure 9 and Figure 13In some embodiments, the free component 130 has a second cavity 134, and the second connecting component 160 is installed in the second cavity 134; the reversing component 122 has an axis of symmetry, and the reversing component 122 is provided with a second card interface 1223 and a third card interface 1224 symmetrically arranged along the axis of symmetry, and the second card interface 1223 is connected to the second cavity 134; when the verification mechanism 200 verifies successfully, the driving component 150 drives the second connecting component 160 to extend out of the second cavity 134 and engage with the second card interface 1223.

[0098] Since the second card interface 1223 is connected to the second cavity 134, after the drive component 150 drives the second connecting component 160 to extend out of the second cavity 134, the second connecting component 160 can engage with the second card interface 1223, thus achieving a fixed connection between the free component 130 and the commutator 122. Because the second card interface 1223 and the third card interface 1224 are symmetrically arranged, when the commutator 122 rotates 180°, the third card interface 1224 connects to the second cavity 134, allowing the second connecting component 160 to extend out of the second cavity 134 and engage with the third card interface 1224, also achieving a fixed connection between the free component 130 and the commutator 122. That is, a 180° rotation of the commutator 122 will not affect its connection with the second connecting component 160.

[0099] Please see Figure 12 In some embodiments, the door lock 10 further includes a reset member 170, which is disposed in the mounting cavity 113. When the reversing member 122 rotates from the initial state, the reset member 170 can reset the reversing member 122 to the initial state.

[0100] The initial state is when the reversing member 122 has not rotated. When the handle member 121 drives the reversing member 122 to rotate in the first or second direction to lock or unlock, the reset member 170 can drive the reversing member 122 and the handle member 121 back to the initial state to prepare for the next rotation.

[0101] Please see Figure 12 , Figure 13 and Figure 16 In some embodiments, the reset member 170 includes an elastic portion 171 and a first pin portion 172 and a second pin portion 173 disposed at both ends of the elastic portion 171. The elastic portion 171 is connected to the inner wall of the mounting cavity 113. The inner wall of the mounting cavity 113 has a first overlapping member 115 and a second overlapping member 116. The reversing member 122 includes a reversing portion 1221 and a first pushing portion 1225 and a second pushing portion 1226 disposed on the reversing portion 1221. The first pin portion 172 overlaps with the first overlapping member 115 and the first pushing portion 1225, and the second pin portion 173 overlaps with the second overlapping member 116 and the second pushing portion 1226.

[0102] by Figure 12 Taking the orientation as an example, the first pin portion 172 is located on the left side of the inner wall of the mounting cavity 113, and the second pin portion 173 is located on the right side of the inner wall of the mounting cavity 113. When the reversing member rotates clockwise, the first pushing part 1225 pushes the first pin portion 172 to rotate clockwise. Since the second pin portion 173 is attached to the second attaching part, the second pin portion 173 does not move. The second pushing part 1226 moves away from the second pin portion 173. During this process, the elastic part 171 is compressed, but after the rotational force disappears, the elastic part 171 is released elastically. The first pin portion 172 pushes the first pushing part 1225 to rotate counterclockwise so that the reversing member 122 returns to the initial state.

[0103] When the reversing member rotates counterclockwise, the second pushing part 1226 pushes the second pin part 173 to rotate counterclockwise. Since the first pin part 172 is attached to the first attachment part, the first pin part 172 remains stationary. The first pushing part 1225 moves away from the first pin part 172. During this process, the elastic part 171 is compressed, but after the rotational force disappears, the elastic part 171 is released elastically. The second pin part 173 pushes the second pushing part 1226 to rotate clockwise so that the reversing member 122 returns to its initial state.

[0104] It should be noted that since the commutator 122 and the free assembly 130 are separated when the reset member 170 resets the commutator 122, the reset member 170 is only used to reset the commutator 122 and the handle 121. The reset of the rotating shaft 310 is achieved by the spring in the rear panel mechanism 400, which is prior art and will not be described further here. Of course, when the second pin portion 173 pushes the second push portion 1226 to rotate clockwise, the protrusion 1222 will also simultaneously push the free assembly 130 to rotate clockwise.

[0105] Please see Figure 12 In some embodiments, one of the first pusher 1225 and the second pusher 1226 is detachably connected to the reversing part 1221.

[0106] As mentioned above, adjusting the mounting direction of the handle 121 requires rotating the reversing member 122. Therefore, to prevent the first pushing part 1225 / second pushing part 1226 from pushing the first pin part 172 / second pin part 173 to move when the reversing member 122 rotates, one of the first pushing part 1225 and the second pushing part 1226 is detachably connected to the reversing member 1221. Figure 12Taking the orientation as an example, the second push part 1226 is detachably connected to the reversing part 1221. When it is necessary to adjust the installation direction of the handle 121, the second push part 1226 is detached. In this way, when the reversing part 122 rotates counterclockwise, the second push part 1226 will not push the second pin part 173 to move. After the reversing part 122 has finished rotating, the second push part 1226 can be reinstalled, so that the direction adjustment of the reversing part 122 does not affect the function of the reset part 170.

[0107] Specifically, one of the first pushing part 1225 and the second pushing part 1226 can be a reversing screw, and the reversing part 1221 is provided with a screw hole 1227, and the reversing screw is screwed into the screw hole 1227.

[0108] Please see Figure 16 In some embodiments, the inner wall of the mounting cavity 113 is further provided with a first stop 117 and a second stop 118. The first stop 117 is disposed near the first pin portion 172 to stop the first pushing portion 1225; the second stop 118 is disposed near the second pin portion 173 to stop the second pushing portion 1226.

[0109] When the reversing member 122 rotates in the first direction, the first pushing part 1225 pushes the first pin part 172 to move in the first direction. When the first pushing part 1225 moves to the first stop part 117, under the stopping action of the first stop part 117, the first pushing part 1225 can no longer move, so the reversing member 122 and the handle part 121 can no longer rotate. Similarly, when the reversing member 122 rotates in the second direction, the second pushing part 1226 pushes the second pin part 173 to move in the second direction. When the second pushing part 1226 moves to the second stop part 118, under the stopping action of the second stop part 118, the second pushing part 1226 can no longer move, so the reversing member 122 and the handle part 121 can no longer rotate. That is, under the combined action of the first stop 117 and the second stop 118, the rotation range of the reversing member 122 and the handle member 121 can be limited, so as to avoid the reversing member 122 from having too large a rotation arc, resulting in excessive elastic potential energy of the elastic part 171, which could damage other structures in the mounting cavity 113.

[0110] Based on the same inventive concept, please refer to Figure 1 This application also provides a door assembly 1, including a door body 20 and the aforementioned door lock 10. A front panel mechanism 100 is disposed on the side of the door body 20, and a portion of the lock body 300 is installed inside the door body 20. The beneficial effects of the door assembly 1 provided in this application are the same as those of the aforementioned door lock 10, and will not be repeated here.
