Description

Technical Field

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

[0002] Smart door locks can lock the door by lifting the handle, which actuates the bolt assembly. After successful user authentication, pressing down the handle activates the bolt assembly to unlock the door. Conversely, if authentication fails, pressing down the handle results in the bolt spinning freely without movement. To ensure these functions, the lock incorporates a rotary dial connected to the handle, a freewheeling component connected to the bolt assembly, and a clutch. The clutch controls the connection between the freewheeling component and the rotary dial, allowing the bolt assembly to be activated based on user authentication information when the handle is pressed down. However, during assembly, the freewheeling component is frequently misinstalled, leading to reassembly and disassembly and reducing installation efficiency.

[0003] Therefore, how to propose a door lock that can prevent foolproof installation of free parts and reduce the probability of incorrect installation of free parts has become an urgent problem to be solved. Utility Model Content

[0004] This application aims to at least address the problem of easy misinstallation of loose parts in door locks, which exists in existing or related technologies.

[0005] Therefore, the first aspect of this application is to propose a panel assembly.

[0006] The second aspect of this application is to propose a door lock.

[0007] The first aspect of this application proposes a panel assembly for a door lock. The door lock includes a lock body and a lock shaft. The lock body includes a bolt assembly. The panel assembly includes: a turntable; a handle connected to the turntable and capable of rotating the turntable; a free element capable of engaging and disengaging from the turntable. When the turntable and the free element are engaged, the free element can rotate with the turntable. When the turntable and the free element are disengaged, the turntable can rotate relative to the free element; and a first limiting structure capable of limiting the rotation angle of the free element within a first angle. When the free element is in a first installation position within the first angle, the free element can be connected to the bolt assembly via the lock shaft and drive the bolt assembly to move via the lock shaft. When the free element is in other installation positions within the first angle, the free element and the lock shaft are misaligned.

[0008] According to the panel assembly provided in this application, a door lock is used, the door lock including a panel assembly, a lock shaft, and a lock body. The lock shaft is used to connect the handle and the bolt assembly of the lock body. The movement of the bolt assembly can be controlled by rotating the handle, thereby realizing operations such as locking and unlocking.

[0009] The panel assembly specifically includes a turntable, a freewheeling component, and a rotatable handle. The turntable and freewheeling component can be engaged or disengaged. When engaged, the handle drives the freewheeling component via the turntable, thereby moving the latch assembly and unlocking the door. When disengaged, the handle rotates the turntable, but the freewheeling component and latch assembly remain stationary, preventing unlocking. To ensure correct installation of the freewheeling component, a first limiting structure is added. This first limiting structure restricts the rotation angle of the freewheeling component within a small range, typically within ±45°. By limiting the rotation angle of the freewheeling component, its installation angle can be controlled, reducing the likelihood of incorrect installation.

[0010] In related solutions, since there is no additional limit on the rotation angle of the freewheeling component, it can rotate to more than 180°. This means that when the freewheeling component rotates to multiple positions, the first shaft hole on the freewheeling component and the second shaft hole on the lock body can be aligned, allowing the freewheeling component to be installed in multiple positions. However, since the freewheeling component also needs to cooperate with the turntable to perform locking and unlocking operations, to ensure that the door lock can perform these operations normally after the freewheeling component is installed, the freewheeling component must be installed correctly. If the freewheeling component is not installed correctly, the door lock cannot perform these functions. To address this issue, this application adds a first limiting structure to the freewheeling component, ensuring that its installation position and orientation are unique. This prevents incorrect installation and achieves foolproof installation of the freewheeling component.

[0011] The technical solution of the second aspect of this application proposes a door lock, including a panel assembly provided by any of the technical solutions of the first aspect; a lock body, the lock body including a bolt assembly; a lock shaft, one end of the lock shaft is connected to a free member, the other end of the lock shaft is connected to the bolt assembly, the lock shaft can rotate with the free member and drive the bolt assembly to move, so as to lock and unlock.

[0012] The door lock proposed according to the technical solution of this application has all the beneficial effects of the panel assembly provided by any of the technical solutions of the first aspect because it includes the panel assembly provided by any of the technical solutions of the first aspect.

[0056] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0057] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0058] The following reference Figures 1 to 39 This application describes panel assemblies and door locks provided according to some embodiments.

[0059] An embodiment of the first aspect of this application provides a panel assembly 1 for a door lock. For example... Figure 1 , Figure 2 and Figure 3 As shown, the door lock includes a panel assembly 1, a lock body 3, and a lock shaft 2. The lock body 3 includes a bolt assembly 30. The bolt assembly 30 can lock and unlock.

[0060] like Figures 4 to 16 As shown, panel assembly 1 includes: a turntable 151; a rotatable handle 12 connected to the turntable 151, capable of driving the turntable 151 to rotate; a free member 154, capable of engaging and disengaging from the turntable 151; when the turntable 151 and the free member 154 are engaged, the free member 154 can rotate with the turntable 151; when the turntable 151 and the free member 154 are disengaged, the turntable 151 can rotate relative to the free member 154; a first limiting structure 11021, and a second limiting structure 11021. A limiting structure 11021 can limit the rotation angle of the free member 154 within a first angle. When the free member 154 is in the first installation position within the first angle, the free member 154 can be connected to the lock tongue assembly 30 through the lock shaft 2 and drive the lock tongue assembly 30 to move through the lock shaft 2. When the free member 154 is in other installation positions within the first angle, the free member 154 and the lock shaft 2 are misaligned, so that the free member 154 cannot be aligned with the lock shaft 2, and thus cannot be connected to the lock tongue assembly 30 through the lock shaft 2.

[0061] According to the panel assembly 1 provided in this application, a door lock is used. The door lock includes the panel assembly 1, a lock shaft 2, and a lock body 3. The lock shaft 2 is used to connect the handle 12 and the bolt assembly 30 of the lock body 3. The movement of the bolt assembly 30 can be controlled by rotating the handle 12, thereby realizing operations such as locking and unlocking.

[0062] The panel assembly 1 specifically includes a turntable 151, a free-moving component 154, and a rotatable handle 12. The turntable 151 and the free-moving component 154 can be engaged or disengaged. When engaged, the handle 12 drives the free-moving component 154 via the turntable 151, thereby moving the latch assembly 30 and unlocking the device. When disengaged, the handle 12 drives the turntable 151 to rotate, but the free-moving component 154 does not move, and the latch assembly 30 does not move, thus unlocking is impossible. To ensure correct installation of the free-moving component 154, a first limiting structure 11021 is additionally provided. This first limiting structure 11021 limits the rotation angle of the free-moving component 154 to a small range, generally within ±45°. By limiting the rotation angle of the free-moving component 154, the installation angle of the free-moving component 154 can be limited, reducing the occurrence of incorrect installation.

[0063] In the relevant design, the free-rotating component 154 can rotate more than 180°. This allows the first shaft hole on the free-rotating component 154 and the second shaft hole (e.g., the second square hole 31) on the lock body 3 to align when the free-rotating component 154 is rotated to multiple positions. This enables the installation of the lock shaft 2 in multiple locations. However, since the free-rotating component 154 also needs to cooperate with the turntable 151 to perform locking and unlocking operations, it is crucial that the free-rotating component 154 is properly installed after installation to ensure that the door lock can perform these operations correctly. If the free-rotating component 154 is not properly installed, the door lock will not be able to perform its normal locking and unlocking functions. To address this issue, this application provides an additional first limiting structure 11021 for the free part 154, which ensures that the free part 154 can only rotate within a first angle. Within this angle, the free part 154 can only be installed with the locking shaft 2 in the first position. In other positions, the free part 154 cannot be installed with the locking shaft 2. This ensures that the installation position of the free part 154 is unique, thereby preventing incorrect installation of the free part 154 and achieving foolproof installation of the free part 154.

[0064] In any of the above embodiments, optionally, as Figure 15 and Figure 16 As shown, the free part 154 is provided with a marking structure 1546 for indicating the installation orientation of the free part 154.

[0065] In this embodiment, the first limiting structure 11021 can limit the installation angle of the free part 154 within a certain range, thus ensuring that the locking shaft 2 can be installed normally after the free part 154 is installed. The marking structure 1546 helps installers quickly determine the installation position of the free part 154, enabling rapid installation and facilitating quick alignment of the first shaft hole 1547 on the free part 154 with the second shaft hole on the lock body 3, improving the installation efficiency of the locking shaft 2. Furthermore, the marking structure 1546 helps installers determine if the free part 154 is installed incorrectly after installation. For example, the marking structure 1546 can be a pointer arrow; if the pointer arrow points in the correct direction, the free part 154 is installed correctly; otherwise, it is installed incorrectly.

[0066] Specifically, the first angle is greater than 0° and less than 90°. Furthermore, the first angle is greater than -45° and less than +45°.

[0067] In this embodiment, the rotation angle of the free element 154 is generally less than 90°. To ensure that the free element 154 is installed in the middle and can rotate to both sides, its rotation angle is within ±45°. This setting makes the installation orientation of the free element 154 unique, thereby reducing the probability of incorrect installation of the free element 154.

[0068] In any of the above embodiments, optionally, the first limiting structure 11021 includes one of the first limiting protrusion 15492, the first limiting groove, and the first limiting hole 110212, and the free member 154 is provided with a limiting engagement structure 1549 adapted to the first limiting structure 11021.

[0069] In this embodiment, the first limiting structure 11021 can be reasonably set as needed. At this time, a corresponding limiting fit structure 1549 can be set on the free part 154. For example, the first limiting structure 11021 and the limiting fit structure 1549 can be set as a fit of protrusion and groove, or a fit of hole and shaft, or a fit of protrusion and protrusion.

[0070] In any of the above embodiments, optionally, as Figure 9 , Figure 13 and Figure 14 As shown, the turntable 151 includes a first mounting hole 1510, and one end of the free member 154 is installed in the first mounting hole 1510. A first stop 1516 is provided on the turntable 151, which is located at the edge of the first mounting hole 1510. A second stop 1542 is provided on the free member 154. When the turntable 151 rotates in the first direction with the handle 12, the first stop 1516 can push the free member 154 to rotate through the second stop 1542, thereby driving the locking tongue assembly 30 to move for locking or unlocking.

[0071] In this embodiment, the turntable 151 is provided with a first mounting hole 1510, and the free member 154 is installed in the first mounting hole 1510, for example, it can be installed in the first mounting hole 1510 through the mounting part 1541. At this time, the clutch shaft 152 can be arranged radially along the first mounting hole 1510, and a fixing groove can be provided on the outside of the first mounting hole 1510 to limit and fix the clutch shaft 152. Further, the turntable 151 is provided with a first stop 1516, and the free member 154 is provided with a second stop 1542. The first stop 1516 and the second stop 1542 are arranged close to each other. When deadbolt operation is required, handle 12 can be rotated, for example, by lifting handle 12. This rotates turntable 151, which in turn pushes second stop 1542 via first stop 1516, thereby rotating the entire freewheeling component 154. This allows the bolt assembly 30 to retract via the freewheeling component 154, thus achieving deadbolt operation. The first direction refers to the direction in which handle 12 is operated for deadbolt operation.

[0072] In any of the above embodiments, optionally, as Figure 9 , Figure 13 and Figure 14 As shown, the turntable 151 is provided with two first stops 1516, which are arranged symmetrically about the diameter of the first mounting hole 1510.

[0073] In this embodiment, the two first stops 1516 are used to cooperate with the second stop 1542 when the turntable 151 is installed at different angles, thereby realizing the deadbolt locking of the door lock. For example, when the handle 12 is installed along the left side, one of the two first stops 1516 cooperates with the second stop 1542. When the turntable 151 rotates with the handle 12 in the first direction, one of the first stops 1516 can push the free member 154 to rotate through the second stop 1542, thereby driving the bolt assembly 30 to move, for locking and unlocking. When the handle 12 is installed along the right side, the other of the two first stops 1516 cooperates with the second stop 1542. When the turntable 151 rotates with the handle 12 in the first direction, the other of the first stops 1516 can push the free member 154 to rotate through the second stop 1542, thereby driving the bolt assembly 30 to move, for locking and unlocking. This structure, with its two symmetrical first stops 1516, facilitates the reversible installation of the handle 12.

[0074] In any of the above embodiments, optionally, as Figure 9 , Figure 10 and Figure 22 As shown, panel assembly 1 further includes: panel 11, on which a second mounting hole 117 is provided, handle 12 is located on the first side of panel 11, and a part of handle 12 extends through the second mounting hole 117 to the second side of panel 11, and handle 12 can rotate relative to panel 11; front base plate 110, mounted on the second side of panel 11, turntable 151 and free member 154 are mounted between the second side of panel 11 and front base plate 110, front base plate 110 is provided with a third mounting hole 1102, free member 154 includes a first connecting part 1545, on which a first shaft hole 1547 is provided, one end of the first connecting part 1545 extends out from the third mounting hole 1102, a first limiting structure 11021 is provided on front base plate 110, and a limiting mating structure 1549 can cooperate with the first limiting structure 11021 to limit the rotation angle of free member 154 within a first angle.

[0075] In this embodiment, panel 11 and front base plate 110 constitute the outer shell structure of panel assembly 1. A portion of handle 12 is inserted between panel 11 and front base plate 110 through second mounting hole 117. Turntable 151 and free member 154 are mounted between the second side of panel 11 and front base plate 110. One end of free member 154, such as first connecting portion 1545, protrudes from third mounting hole 1102. First limiting structure 11021 is provided on front base plate 110. First connecting portion 1545 is provided with limiting engagement structure 1549. The rotation angle of free member 154 can be limited by limiting engagement structure 1549 and first limiting structure 11021, thus the rotation angle of free member 154 can be limited by front base plate 110.

[0076] In any of the above embodiments, optionally, as Figure 15 As shown, the limiting fit structure 1549 includes a first limiting protrusion 15492 disposed on the outer side wall of the first connecting portion 1545. For example... Figure 22 As shown, the first limiting structure 11021 includes a first limiting hole 110212 disposed on the front base plate 110. For example... Figure 36 As shown, the first limiting hole 110212 is part of the third mounting hole 1102, and the first limiting protrusion 15492 is limited and mounted in the first limiting hole 110212.

[0077] In this embodiment, a first limiting protrusion 15492 can be provided on the outer side wall of the first connecting portion 1545, and a first limiting hole 110212 can be provided on the front base plate 110. This allows for limiting between the first connecting portion 1545 and the front base plate 110 based on the protrusion and hole. To facilitate the installation of the clutch 154, the third mounting hole 1102 can be divided into two parts: a first part for the passage of the first connecting portion 1545, and a second part for the passage of the first limiting protrusion 15492. In this structure, at least a portion of the third mounting hole 1102 forms the first limiting hole 110212. Alternatively, the third mounting hole 1102 and the first limiting hole 110212 can be understood as being interconnected, thus merging into a single large hole.

[0078] Furthermore, such as Figure 15 and Figure 22 As shown, the third mounting hole 1102 includes a first arcuate sidewall 11022 and a second arcuate sidewall 11023 connected to each other in the circumferential direction. The first arcuate sidewall 11022 constitutes a first limiting hole 110212. The radius of the second arcuate sidewall 11023 is smaller than the radius of the first arcuate sidewall 11022, and / or the central arc angle corresponding to the second arcuate sidewall 11023 is larger than the central arc angle corresponding to the first arcuate sidewall 11022.

[0079] In this embodiment, the sidewall of the third mounting hole 1102 is divided into two sections: a first arc-shaped sidewall 11022 and a second arc-shaped sidewall 11023. The first arc-shaped sidewall 11022 forms the first limiting hole 110212. The first arc-shaped sidewall 11022 also forms a hole through which the first connecting portion 1545 passes. During design, the first hole required for the first connecting portion 1545 can be machined first, and then expanded outwards from the first hole to form the second hole, thus forming a large hole composed of the second arc-shaped sidewall 11023 and the first arc-shaped sidewall 11022. Therefore, after the third mounting hole 1102 is machined, the radius of the second arc-shaped sidewall 11023 is smaller than the radius of the first arc-shaped sidewall 11022. Simultaneously, since the width required for the first limiting protrusion 15492 is relatively narrow, the first arc-shaped sidewall 11022 can be set narrower, while the second arc-shaped sidewall 11023 can be set wider.

[0080] In any of the above embodiments, optionally, as Figure 13 and Figure 14 As shown, panel assembly 1 also includes a clutch assembly, mounted on turntable 151. Figure 20 and Figure 21 As shown, the drive device 18 is connected to the clutch assembly and can drive the clutch assembly to move so that the free element 154 and the turntable 151 can be engaged and disengaged through the clutch assembly.

[0081] In this embodiment, the drive device 18 can specifically be a motor 182. The drive device 18 is used to drive the clutch assembly to actuate, thereby changing the relative position of the clutch assembly and the free element 154, and thus changing the connection state between them. Since the clutch assembly itself is mounted on the turntable 151, when the clutch assembly engages with the free element 154, the turntable 151 and the free element 154 can be engaged; when the clutch assembly disengages from the free element 154, the turntable 151 and the free element 154 can be disengaged. This structure, by driving the clutch assembly through the drive device 18, can achieve automated control of the engagement and disengagement between the turntable 151 and the free element 154, making the operation of the door lock more intelligent.

[0082] In any of the above embodiments, optionally, as Figures 13 to 16 As shown, the free-moving component 154 is provided with a clutch groove 1543. The clutch assembly includes a clutch shaft 152, which can move along the length direction of the clutch groove 1543 to insert into or slide out of the clutch groove 1543. The cooperation between the clutch shaft 152 and the clutch groove 1543 enables the free-moving component 154 to engage and disengage from the turntable 151. By sliding the clutch shaft 152, it can be inserted into or slid out of the clutch groove 1543, thereby realizing the separation and engagement connection between the turntable 151 and the free-moving component 154.

[0083] In any of the above embodiments, optionally, as Figure 16 and Figure 17 As shown, the free part 154 is mounted on the turntable 151. The free part 154 includes: a mounting part 1541, which is mounted on the turntable 151 and has a clutch groove 1543; and a first connecting part 1545, which is located at one end of the mounting part 1541 away from the turntable 151 and has a first shaft hole 1547. The first connecting part 1545 can be connected to the locking shaft 2 through the first shaft hole 1547.

[0084] In this embodiment, the first end of the free-moving member 154 is configured as a mounting portion 1541 for mounting the free-moving member 154 to the turntable 151. The second end of the free-moving member 154 is configured as a first connecting portion 1545 for connecting the free-moving member 154 to the locking shaft 2. By directly mounting the free-moving member 154 onto the turntable 151, the structure between the two can be made more compact.

[0085] Optionally, such as Figure 16 and Figure 17 As shown, the clutch groove 1543 is provided on one end of the mounting part 1541 near the turntable 151, and the clutch groove 1543 and the clutch shaft 152 are arranged radially along the first shaft hole 1547.

[0086] In this embodiment, the clutch groove 1543 is disposed on the surface of the mounting portion 1541 near the turntable 151, that is, the clutch groove 1543 is disposed at the bottom of the mounting portion 1541 and extends through one side edge of the bottom of the mounting portion 1541. The clutch shaft 152 is mounted on the surface where the turntable 151 and the mounting portion 1541 contact. Furthermore, the clutch groove 1543 and the clutch shaft 152 are disposed along the radial direction of the first shaft hole 1547. Of course, the clutch groove 1543 and the clutch shaft 152 can also be disposed in other directions.

[0087] In any of the above embodiments, optionally, as Figure 13 and Figure 14 As shown, there are two clutch grooves 1543 and two clutch shafts 152. The two clutch grooves 1543 and the two clutch shafts 152 are centrally symmetrical about the center of the turntable 151.

[0088] In this embodiment, by setting the clutch groove 1543 and the clutch shaft 152 as a symmetrical structure, the clutch shaft 152 can still cooperate with the drive device 18 after the turntable 151 and the free element 154 rotate 180°, which facilitates the reversing installation of the handle 12.

[0089] In any of the above embodiments, optionally, as Figure 10 and Figure 11As shown, a fixing groove 15110 is provided on the turntable 151, and at least a portion of the clutch shaft 152 is installed in the fixing groove 15110. The fixing groove 15110 can limit and guide the clutch shaft 152, preventing situations such as improper installation of the clutch shaft 152 or displacement during sliding.

[0090] There are two fixing slots 15110, and the two fixing slots 15110 are arranged symmetrically.

[0091] Optionally, such as Figure 9 , Figure 13 and Figure 14 As shown, the clutch assembly also includes a clutch spring 153, which is sleeved on the clutch shaft 152. A limiting step 1522 is provided on the clutch shaft 152 to limit one end of the clutch spring 153. The other end of the clutch spring 153 is limited on the turntable 151. When the clutch shaft 152 is inserted into the clutch groove 1543, the clutch spring 153 is in a compressed state.

[0092] In this embodiment, the clutch spring 153 can generate a rebound force after the clutch shaft 152 moves into the clutch groove 1543, so as to help the clutch shaft 152 quickly return to the initial position.

[0093] In any of the above embodiments, optionally, as Figure 9 , Figure 17 , Figure 18 and Figure 19 As shown, the panel assembly 1 also includes a clutch cover 155, which is mounted on the turntable 151. A mounting portion 1541 is mounted between the clutch cover 155 and the turntable 151. The clutch cover 155 has a through hole, through which at least a portion of the first connecting portion 1545 can protrude. A clutch shaft 152 is mounted between the clutch cover 155 and the turntable 151. The clutch cover 155 also has a second limiting structure 1555 to limit the clutch shaft 152.

[0094] In this embodiment, the clutch cover 155 can limit the positions of the free-moving component 154 and the clutch shaft 152, preventing the free-moving component 154 and the clutch shaft 152 from disengaging from the turntable 151. The through hole consists of two parts: a first part hole 1553 and a second part hole 1554. The first part hole 1553 facilitates the passage of the first connecting part 1545, while the second part hole 1554 allows for avoidance of the limiting fit structure 1549 on the first connecting part 1545.

[0095] In any of the above embodiments, optionally, as Figures 26 to 30As shown, the handle 12 and the turntable 151 can rotate 180° relative to the panel 11, so that the handle 12 can be mounted on a first side of the panel 11 along the width direction of the panel, or on a second side of the panel 11 along the width direction of the panel. The turntable 151 is provided with a second screw hole 1519. The front base plate 110 is provided with two reversing holes 1103 along the width direction of the panel. By engaging the reversing screw 16 with one of the two reversing holes 1103 and the second screw hole 1519, the handle 12 can be mounted on the first side of the panel 11 along the width direction of the panel, or on a second side of the panel 11 along the width direction of the panel.

[0096] In this embodiment, the handle 12 has two installation orientations, allowing it to be installed on the left or right side as needed. In this configuration, the handle 12 and the turntable 151 can rotate 180° relative to the panel 11. Before rotation, the second screw hole 1519 is aligned with one of the two reversing holes 1103, and the handle 12 can be installed on one side of the panel 11 along its width using the reversing screw 16. After rotation, the second screw hole 1519 is aligned with the other of the two reversing holes 1103, and the handle 12 can be installed on the other side of the panel 11 along its width using the reversing screw 16. This structure allows the handle 12 to be installed in two different positions, thus achieving two installation methods. The reversing method of this handle 12 does not require disassembling the panel assembly 1. It only requires removing the reversing screw 16 and then rotating the handle 12 and the turntable 151 180° to adjust the installation direction of the handle 12.

[0097] In any of the above embodiments, optionally, as Figure 5 As shown, on the second side of panel 11, a ring of annular ribs 113 is provided around the third mounting hole 1102. Figure 4 and Figure 7 As shown, panel assembly 1 also includes a bearing 13, which is installed within an annular rib 113. One end of the turntable 151 near the panel 11 is rotatably supported within the annular rib 113 via the bearing 13, and the other end of the turntable 151 near the panel 11 is also inserted into and connected to the handle 12. Supporting the turntable 151 with the bearing 13 allows for smoother rotation of the turntable 151.

[0098] Furthermore, a through circular hole 1514 is provided in the center of the turntable 151 (e.g., Figure 11 As shown, the handle 12 and the turntable 151 are connected by a through circular hole 1514 and a second fixing screw 17. The panel 11 and the front base plate 110 are fixed by a third fixing screw 111.

[0099] Furthermore, such as Figure 4 As shown, a base plate silicone 19 is installed between the panel 11 and the front base plate 110 to achieve a seal between the panel 11 and the front base plate 110.

[0100] Furthermore, such as Figure 4 and Figure 8 As shown, the panel assembly 1 also includes a torsion spring 14, which is mounted on the panel 11 and can be twisted along with the handle 12. It is used to deform when the turntable 151 rotates, so as to provide rotational force for the rotation of the turntable 151.

[0101] like Figures 1 to 39 As shown, the second embodiment of this application proposes a door lock, including a panel assembly 1 provided in any embodiment of the first aspect; a lock body 3, including a bolt assembly 30; a lock shaft 2, one end of which is connected to a free member 154, and the other end of which is connected to the bolt assembly 30. The lock shaft 2 can rotate with the free member 154 and drive the bolt assembly 30 to move, so as to realize unlocking and locking.

[0102] The door lock proposed in the embodiments of this application has all the beneficial effects of the panel assembly 1 provided in the above embodiments because it includes the panel assembly provided in any of the above embodiments.

[0103] Furthermore, the locking shaft 2 is a square shaft. The free-moving component 154 has a first square hole, and the lock body 3 includes a second square hole 31. One end of the locking shaft 2 is connected to the free-moving component 154 through the first square hole, and the other end of the locking shaft 2 is connected to the bolt assembly 30 through the second square hole 31. This arrangement improves the connection strength between the locking shaft 2 and the free-moving component 154, and between the locking shaft 2 and the bolt assembly 30, reducing the occurrence of slippage in the locking shaft 2.

[0104] like Figures 1 to 39 As shown, this utility model relates to a smart door lock panel handle reversing and unlocking structure, such as... Figure 1 and Figure 2 As shown, the structure includes:

[0105] Panel assembly 1, square shaft (i.e., locking shaft 2), and lock body 3. The square shaft is used to connect the free-moving part 154 and the lock body 3. When the free-moving part 154 rotates, it can drive the square shaft (i.e., locking shaft 2) to rotate together, thereby driving the latch 32 and the main latch 33 of the lock body 3 to move together.

[0106] like Figure 3 As shown, the lock body 3 has a second square hole 31 in the middle, a beveled tongue 32 on the side, and a main lock tongue 33. The second square hole 31 is connected to a square shaft. When the second square hole 31 rotates in the upward direction of the handle 12, the main lock tongue 33 extends to achieve reverse locking; when the handle 12 rotates in the downward direction of the handle 12, the main lock tongue 33 and the beveled tongue 32 retract to achieve unlocking.

[0107] like Figure 4 As shown, panel assembly 1 includes panel 11, handle 12, bearing 13, torsion spring 14, turntable assembly 15, reversing screw 16, second fixing screw 17, motor 182, base plate silicone 19, front base plate 110, and third fixing screw 111.

[0108] like Figure 5 As shown, panel 11 has screw posts 112 inside for connecting the front base plate 110 and the third fixing screw 111; panel 11 has annular ribs 113 inside for fixing the bearing 13; panel 11 has first limiting ribs 114 and second limiting ribs 116 inside for limiting the torsion spring 14 when the handle 12 is rotated; panel 11 has a raised cylinder 115 inside for positioning the motor 182.

[0109] like Figure 6 As shown, the recessed square hole 121 at the bottom of the handle 12 mates with the raised structure 1511 at the bottom of the turntable 151. The recessed notch 122 at the bottom mates with the raised rib 1512 at the bottom of the turntable 151, serving as a positioning and error-proofing feature. The recessed square hole 121 at the bottom of the handle 12 has a first screw hole 123, which is connected to the second fixing screw 17 during assembly.

[0110] like Figure 7 As shown, when the bearing 13 is assembled, the outer ring 131 is interference-fitted inside the annular rib 113 of the panel 11, and the cylindrical structure 1513 under the turntable 151 passes through the inner ring 132 of the bearing 13.

[0111] like Figure 8 As shown, the torsion spring 14 has a spiral structure. The inner ring 141 of the spring is sleeved on the outside of the annular rib 113 of the panel 11. There is a pin 142 on each side, which is assembled and locked at the first limiting rib 114 and the second limiting rib 116 of the panel 11. When the handle 12 drives the turntable 151 to rotate, the spring deformation generates a rotational force for the rotation of the turntable 151.

[0112] like Figure 9 As shown, the turntable assembly 15 includes a turntable 151, a clutch shaft 152, a clutch spring 153, a free element 154, a clutch cover 155, and a first fixing screw 156.

[0113] like Figure 10 and Figure 11As shown, the bottom protrusion 1511 of the turntable 151 mates with the bottom recessed square hole 121 of the handle 12 during assembly. The bottom protrusion rib 1512 mates with the bottom recessed notch 122 of the handle 12 during assembly, serving as a positioning and error-proofing function. The bottom of the turntable 151 has a cylindrical structure 1513 that passes through the inner ring 132 of the bearing 13 during assembly. The center of the turntable 151 has a through circular hole 1514 running from top to bottom. During assembly, the second fixing screw 17 passes through this circular hole and is fixed to the first screw hole 123 at the bottom of the handle 12. The upper part of the turntable 151 has a recessed circular notch 1515, in which the mounting part 1541 of the free element 154 is assembled and can rotate along the center line of the recessed circular notch 1515. Above the recessed circular notch 1515 of the turntable 151, there are two first stops 1516. When the turntable 151 rotates around the center line and the first stops 1516 contact the second stops 1542 of the free element 154, the free element 154 can be driven to rotate around the center line together. The upper part of the turntable 151 has a threaded hole 1518 and a positioning post 1517 for assembling and positioning the clutch cover 155 and the first fixing screw 156. The threaded hole 1518 is connected to the first fixing screw 156, and the positioning post 1517 passes through the positioning hole 1551 of the clutch cover for positioning. The turntable 151 has a second screw hole 1519 for the reversing screw 16 to pass through during assembly; the upper part of the turntable 151 has two fixing grooves 15110, and the diameter of the middle part of each fixing groove 15110 is larger than that of the two ends, and the clutch shaft 152 and the clutch spring 153 are assembled therein.

[0114] like Figure 12 As shown, the clutch shaft 152 has a symmetrical structure with small diameters at both ends and a large diameter for the limiting step 1522. Figure 9 As shown, the clutch spring 153 has a spiral structure.

[0115] like Figure 13 and Figure 14 As shown, during assembly of the turntable 151, clutch shaft 152, and clutch spring 153, the clutch spring 153 is fitted onto the clutch shaft 152, and then assembled together with the clutch shaft into the fixing groove 15110 of the turntable 151. The clutch shaft limiting step 1522 and the clutch spring 153 are engaged in the fixing groove 15110 of the turntable 151, and the clutch spring 153 is in a compressed state, with one end of the clutch shaft protruding from the outer notch of the fixing groove 15110. When the clutch shaft moves towards the center of the turntable 151, the clutch spring 153 will be further compressed, and the other end of the clutch shaft will protrude from the inner notch of the fixing groove 15110.

[0116] like Figure 15 and Figure 16As shown, the mounting portion 1541 of the free-electrode 154 is cylindrical in shape, and has a second stop 1542, a clutch groove 1543, and a circular hole 1544, wherein the clutch groove 1543 is located directly below the second stop 1542. When the turntable assembly 15 is assembled, the mounting portion 1541 of the free-electrode 154 is fitted into the recessed circular notch 1515 of the turntable 151. When the turntable 151 rotates around its center line, and the first stop 1516 of the turntable 151 contacts the second stop 1542 of the free-electrode 154, it can drive the free-electrode 154 to rotate together around the center line. When one end of the clutch shaft extends from the inner notch 15110 of the turntable 151, it can be inserted into the clutch groove 1543 at the bottom of the free-electrode.

[0117] The first connecting portion 1545 of the free part 154 is cylindrical in shape and has a marking structure 1546. The radius of the first connecting portion 1545 is smaller than that of the mounting portion 1541. The inner side of the first connecting portion 1545 has a first square hole (specifically a first shaft hole 1547), and the periphery of the first square hole has rounded corners 1548. The outer side of the first connecting portion 1545 has a first limiting protrusion 15492. When the panel 11 is assembled, this protrusion extends from the first limiting hole 110212 of the front bottom plate 110.

[0118] like Figure 17 and Figure 18 As shown, the clutch cover 155 has positioning holes 1551 and third screw holes 1552 on both sides. During turntable assembly, the positioning pin 1517 of the turntable 151 passes through the positioning hole 1551 of the clutch cover 155, and the first fixing screw 156 passes through the third screw hole 1552 of the clutch cover 155, connecting with the threaded hole 1518 of the turntable 151. When the turntable 151 rotates around its center line, it will cause the clutch cover 155 to rotate along with it. The clutch cover 155 has a first partial hole 1553 and a second partial hole 1554 in the middle. During turntable assembly 15, the first connecting portion 1545 of the free member 154 passes through the hole formed by the first partial hole 1553 and the second partial hole 1554. When the turntable 151 and the clutch cover 155 rotate around their center line, the second partial hole 1554 will avoid the first limiting protrusion 15492 of the free member 154.

[0119] like Figure 19 As shown, the bottom of the clutch cover 155 has two second limiting structures 1555, specifically second limiting protrusions 15552. The second limiting structures 1555 can limit the clutch shaft 152, so that the clutch shaft 152 moves along its center line, avoiding deviation or jamming during movement.

[0120] like Figure 9 As shown, the first fixing screw 156 passes through the third screw hole 1552 of the clutch cover 155 during the assembly of the turntable assembly 15 and connects to the threaded hole 1518 of the turntable 151.

[0121] like Figure 4 As shown, when the panel assembly 1 is assembled, the reversing screw 16 passes through the reversing hole 1103 of the front base plate 110 and connects to the second screw hole 1519 of the turntable 151.

[0122] like Figure 4 As shown, the second fixing screw 17 passes through the through circular hole 1514 during the assembly of the panel assembly 1 and is fixed to the first screw hole 123 at the bottom of the handle 12.

[0123] like Figure 20 and Figure 21 As shown, the top of the motor 182 has an arc-shaped push block 1822. When the user does not perform unlock verification, or the unlock verification fails, the push block 1822 remains retracted. When the user successfully verifies the unlock, the push block 1822 extends, pushing the clutch shaft 152 into the clutch groove 1543 below the free element 154, thus closing the clutch. At this time, rotating the turntable 151 will cause the free element 154 to rotate along with it via the clutch shaft 152. Figure 4 As shown, the base plate silicone 19 is sandwiched between the panel 11 and the front base plate 110 during the assembly of the panel assembly 1.

[0124] like Figure 22 As shown, the front base plate 110 has a fourth screw hole 1101 at the corner. When the panel assembly 1 is assembled, the third fixing screw 111 passes through the fourth screw hole 1101 and is connected to the screw post 112 of the panel 11.

[0125] The front base plate 110 has a third mounting hole 1102, through which the free-moving component 154 passes during panel assembly 1 assembly. Below the third mounting hole 1102 are symmetrical first limiting holes 110212, which limit the rotation angle of the free-moving component 154 by restricting the rotation of the first limiting protrusion 15492 on the outer side of the top of the free-moving component when it rotates left or right. On the left and right sides of the third mounting hole 1102, the front base plate 110 has reversing holes 1103, through which reversing screws 16 pass during panel assembly 1 assembly and connect to the second screw hole 1519 of the turntable 151.

[0126] like Figure 4 As shown, when the panel assembly 1 is assembled, the third fixing screw 111 passes through the fixing fourth screw hole 1101 of the front base plate 110 and is connected to the screw post 112 of the panel 11.

[0127] The following explains how lifting handle 12 can cause lock body 3 to lock:

[0128] like Figure 23 , Figure 24 and Figure 25 As shown, the state before lifting handle 12 is as follows Figure 23 As shown, when the handle 12 is lifted, the turntable 151 rotates along with it. When the first stop 1516 of the turntable 151 contacts the second stop 1542 of the free part 154, it drives the free part 154 and the square shaft to rotate together, thereby driving the lock body 3 to lock and the main bolt 33 to be released.

[0129] The state after lifting handle 12 is as follows Figure 24 and 25 As shown, by Figures 23 to 25 The comparison shows that when handle 12 is lifted, turntable 151, free part 154, and square shaft all rotate clockwise by a certain angle.

[0130] The following explanation addresses the issue where, when the clutch is not engaged, pressing down on handle 12 causes it to spin freely and fails to unlock the lock body 3:

[0131] like Figure 26 , Figure 27 and Figure 28 As shown, when the user does not perform unlock verification, or the unlock verification fails, the push block 1822 of the motor 182 remains in the retracted state. The clutch shaft 152 is not pushed into the freewheeling element 154, the clutch is not closed, and when the handle 12 is pressed down, the turntable 151 rotates with the handle 12, but the freewheeling element 154 and the square shaft do not rotate with it. The lock body 3 does not move and cannot unlock; the bolt 32 and the main bolt 33 do not retract.

[0132] Among them, through Figure 26 , Figure 27 and Figure 28 The comparison shows that after the handle 12 is pressed down, the turntable 151 rotates counterclockwise by a certain angle, but the free part 154 and the square shaft do not rotate.

[0133] The following explains how pressing down on handle 12 when the clutch is closed can unlock the lock body 3:

[0134] like Figure 29 , Figure 30 and Figure 31 As shown, when the user verifies the unlocking, the push block 1822 of the motor 182 extends, pushing the clutch shaft 152 into the free element 154, and the clutch is closed. When the handle 12 is pressed down, the turntable 151, clutch shaft 152, free element 154, and square shaft rotate together, driving the lock body 3 to unlock, and the oblique bolt 32 and main bolt 33 retract.

[0135] Among them, through Figure 29 , Figure 30 and Figure 31 The comparison shows that after the handle 12 is pressed down, the turntable 151, the free part 154, and the square shaft all rotate counterclockwise by a certain angle.

[0136] The following explains how to easily switch the handle 12 by replacing the reversing screw:

[0137] like Figure 32 , Figure 33 , Figure 34 and Figure 35 As shown, when the reversing screw 16 is not driven, the handle 12 can be rotated to switch between right-open and left-open states. When the second screw hole 1519 of the turntable 151 appears below the reversing hole 1103 of the front base plate 110, the reversing screw 16 can be driven into the second screw hole 1519 to complete the convenient reversing of the handle 12 without disassembling the base plate.

[0138] in, Figure 32 This is a schematic diagram of the handle 12 in the left-open position when the reversing screw 16 is not driven in. Figure 33 This is a schematic diagram of the handle 12 in the right-open position when the reversing screw 16 is not driven in. Figure 34 A schematic diagram of the structure when the handle 12 is in the left open position when the reversing screw 16 is driven in. Figure 35 A schematic diagram of the structure when the handle 12 is in the right-open position when the reversing screw 16 is driven in.

[0139] The following explains the foolproof installation structure for free parts:

[0140] like Figure 36 , Figure 37 , Figure 38 and Figure 39 As shown, the free part 154 protrudes from the third mounting hole 1102 of the front base plate 110. Below the third mounting hole 1102, there are left and right symmetrical first limiting holes 110212. When the free part 154 rotates left and right, it can limit the first limiting protrusion 15492 on the outer side of the top of the free part, thereby limiting the free rotation angle of the free part.

[0141] When the square shaft is installed correctly, the marking structure 1546 of the free part 154 should face downwards (e.g., Figure 36 (As shown). Without the restriction of the left and right symmetrical first limiting holes 110212 on the base plate, the free member 154 can rotate freely within a range of 180°, and the free member 154 may rotate to a state where the marking structure 1546 faces horizontally (as shown). Figure 38 (as shown) or facing upwards (as shown) Figure 39 If the lock body 3 is in a state as shown (as indicated), it will lead to an installation error, and the lock body 3 will be unable to lock or unlock. By restricting the movement through the symmetrical first limiting holes 110212, the free-moving part 154 can only rotate automatically within a range of less than 90°, thus ensuring that the marking structure 1546 can only face downwards when the square shaft is installed, thereby preventing mistaken installation. Specifically, when the free-moving part 154 can only rotate automatically within a range of less than 90°, if its marking structure 1546 faces diagonally downwards (as shown), it will cause an installation error. Figure 37When the square shaft cannot be installed (as shown), the installer should be reminded that the installation angle of the free part 154 is incorrect, thus ensuring that the free part 154 can only be installed as shown. Figure 36 Installing it at that angle ensures the uniqueness of the installation position of the free part.

[0142] In the description of this specification, the terms "connection," "installation," and "fixing," etc., should be interpreted broadly.
