Description

Technical Field

[0001] This application relates to the field of lock technology, and in particular to a reset module and a smart door lock. Background Technology

[0002] In the iterative development of smart lock technology, the internal components of a smart lock need to accommodate fingerprint modules, motor drives, emergency keyholes, and other parts. Therefore, the lock face needs to have precisely designed mounting cavities, wiring channels, and positioning structures. The manufacturing processes for the lock face and reset components of smart locks include die casting and stamping. Die casting involves filling a mold cavity with molten metal under high pressure to create the lock face and reset components. This process can form complex structures with deep cavities, bosses, reinforcing ribs, and irregularly shaped holes in a single step, thus perfectly adapting to the functional integration requirements of smart lock faces. Stamping involves applying pressure to a metal sheet at room temperature using a mold, utilizing the sheet's ductility to cause plastic deformation or separation of the material, thereby creating the lock face and reset components. This process has the advantages of low cost and high efficiency.

[0003] However, regardless of whether smart locks are manufactured using die-casting or stamping processes, they all employ a process of installing and resetting components (such as springs, connectors, and pivots) on-site one by one. This introduces errors at each assembly step, which, when accumulated, can lead to problems such as handle jamming or incomplete handle reset, negatively impacting the user experience. Utility Model Content

[0004] This utility model discloses a reset module and a smart door lock, which enables the reset module to be pre-assembled into an independent module, thereby improving the reset accuracy of the reset module.

[0005] To achieve the above objectives, the first aspect of this utility model discloses a reset module, comprising:

[0006] The base has a first shaft hole and a snap-fit ​​part. The first shaft hole is located in the middle of the base, and the snap-fit ​​part is located near the edge of the base and is spaced apart from the first shaft hole.

[0007] A pivot has a first end and a second end along its axial direction, the first end being configured to rotatably pass through a first shaft hole to connect with the handle, and the second end being located on the side of the base opposite to the handle;

[0008] A connector, fixedly sleeved at the second end, the connector having a actuating element protruding towards the base along the axial direction of the rotating shaft, the connector being configured to drive the actuating element to rotate when the rotating shaft rotates; and

[0009] An elastic reset member is sleeved on the second end and located between the base and the connector along the axial direction of the rotating shaft. The elastic reset member at least partially abuts against the actuating member and at least partially engages with the locking portion. The elastic reset member is configured to rotate and generate torsional deformation under the drive of the actuating member to provide a reset force for the actuating member and the rotating shaft.

[0010] The reset module of this application provides a unified installation reference through the base. The rotating shaft forms a precise rotational fit with the base through the first shaft hole, eliminating the need for additional bearings. The elastic reset component achieves radial positioning by sleeved on the rotating shaft and circumferential positioning by engaging with the base's snap-fit ​​part. Simultaneously, it is axially clamped by the base and connecting parts, thus enabling the pre-assembly of all components within the reset module. This allows the entire reset module to be pre-assembled as an independent module, improving assembly accuracy during pre-assembly and preventing reset jamming or failure during installation in a smart lock.

[0011] Secondly, the reset module can be manufactured separately, and the elastic reset component inside the reset module can rotate and be compressed under the drive of the actuating component to provide the resetting force for the actuating component and the rotating shaft. This allows the assembled reset module to be tested for rotational reset before leaving the factory, so that the reset accuracy problem of the reset module can be checked in time during the production process, thereby avoiding the need for rework after the reset module is installed in the smart door lock.

[0012] Furthermore, the base, connectors, and other components in the reset module of this application do not require the fabrication of complex deep cavities or positioning posts, allowing them to be manufactured using processes such as stamping, which helps reduce the production cost of the reset module. Moreover, stamping enables the rapid production of standardized components, allowing for the quick production of components such as the base, shaft, and connectors, thus improving the production efficiency of the reset module.

[0013] As an optional implementation, the elastic reset member includes:

[0014] The main body is sleeved on the rotating shaft;

[0015] First torsion arm;

[0016] The second torsion arm extends from the main body away from the rotating shaft along the radial direction of the rotating shaft. The second torsion arm and the first torsion arm are arranged opposite to each other along the radial direction of the rotating shaft. The first torsion arm is connected to the base, and the second torsion arm is engaged with the engaging part. The actuating member is disposed below the second torsion arm and abuts against the second torsion arm. The actuating member is configured to drive the second torsion arm to rotate along a first rotation direction when the rotating shaft rotates, so that the elastic reset member is compressed.

[0017] The main body of the torsion spring is sleeved on the rotating shaft, and the first torsion arm and the second torsion arm extend in the radial direction of the rotating shaft. This allows the elastic reset component to be fully accommodated in the axial space between the base and the connecting component. As a result, the elastic reset component can be supported without the need for an external structure of the reset module, and the entire reset module can be assembled and manufactured and reset tested independently.

[0018] As an optional implementation, the snap-fit ​​portion includes two snap-fit ​​portions, which are arranged opposite to each other along the radial direction of the rotating shaft, and the first torsion arm and the second torsion arm are respectively snapped into the corresponding snap-fit ​​portion;

[0019] The actuating element includes two parts, namely a first actuating element and a second actuating element. The first actuating element and the second actuating element are arranged opposite each other in the radial direction of the rotating shaft, and the first actuating element and the second actuating element are spaced apart from the base in the axial direction of the rotating shaft.

[0020] Wherein, the first actuating member is disposed below the first torsion arm and abuts against the first torsion arm, and the second actuating member is disposed below the second torsion arm and abuts against the second torsion arm;

[0021] When the rotating shaft is configured to rotate along the first rotation direction, the second actuating member drives the second torsion arm to rotate and compress the main body, so that the second torsion arm and the main body provide a resetting force for the second actuating member and the rotating shaft; when the rotating shaft is configured to rotate along the second rotation direction, the first actuating member drives the first torsion arm to rotate and compress the main body, so that the first torsion arm and the main body provide a resetting force for the first actuating member and the rotating shaft.

[0022] The second rotation direction is opposite to the first rotation direction.

[0023] Two locking parts are arranged radially opposite to each other along the rotating shaft. A first torsion arm and a second torsion arm are respectively locked into the two locking parts. A first actuating member abuts against the lower part of the first torsion arm. When the rotating shaft rotates in the first rotation direction, the second actuating member can drive the second torsion arm to rotate and compress the main body, so that the second torsion arm and the main body provide a resetting force for the second actuating member and the rotating shaft. Thus, when the handle rotates in the first rotation direction, the second actuating member can drive the second torsion arm to rotate and compress the main body, thereby providing a resetting force for the second actuating member and the rotating shaft. Furthermore, when the rotating shaft rotates in the second rotation direction, the first actuating member can drive the first torsion arm to rotate and compress the main body, so that the first torsion arm and the main body provide a resetting force for the first actuating member and the rotating shaft. Thus, when the handle rotates in the second rotation direction, the first actuating member can drive the first torsion arm to rotate and compress the main body, thereby providing a resetting force for the first actuating member and the rotating shaft. Simultaneously, the second rotation direction is opposite to the first rotation direction. In this way, whether the handle is turned in the first rotation direction or the second rotation direction (for example, the first rotation direction is turning the handle downwards and the second rotation direction is turning the handle upwards), the handle can be reset by the elastic reset component providing the actuating force of the actuating component and the rotating shaft. This eliminates the need for two separate reset modules for unlocking and locking the same handle, thereby improving the compatibility of the reset module and reducing its cost.

[0024] As an optional implementation, the snap-fit ​​portion includes two snap-fit ​​portions, which are arranged opposite to each other along the radial direction of the rotating shaft, and the first torsion arm and the second torsion arm are respectively snapped into the corresponding snap-fit ​​portion;

[0025] The actuating element includes two parts, namely a first actuating element and a second actuating element. The first actuating element and the second actuating element are arranged opposite to each other in the radial direction of the rotating shaft, and the first actuating element and the second actuating element are spaced apart from the base in the axial direction of the rotating shaft. The first actuating element is welded to the connecting element, and the second actuating element is detachably connected to the connecting element.

[0026] The handle has a first unlocking direction and a second unlocking direction. When the handle is unlocked in the first unlocking direction, the first actuating member abuts against the first torsion arm, and the second actuating member abuts against the second torsion arm. When the handle is unlocked in the second unlocking direction, the first actuating member abuts against the second torsion arm, and the second actuating member abuts against the first torsion arm.

[0027] When the handle is switched between the first unlocking direction and the second unlocking direction, the second actuating member is separated from the connecting member, so that the handle drives the rotating shaft and the first actuating member to rotate, so that the first actuating member abuts against the second torsion arm, and the second actuating member is configured to abut against the first torsion arm when installed on the connecting member;

[0028] The first unlocking direction and the second unlocking direction are opposite.

[0029] The handle is detachably connected to the connector via a second actuating element. The handle has opposite first and second unlocking directions. When the handle is operated in the first unlocking direction (e.g., right-opening), the first actuating element abuts against the first torsion arm, and the second actuating element abuts against the second torsion arm, thus achieving bidirectional resetting of the handle when unlocking in the first unlocking direction. When it is necessary to switch the handle's unlocking direction from the first to the second unlocking direction (e.g., left-opening), the second actuating element can be removed. By rotating the handle, the shaft and the first actuating element rotate together, causing the first actuating element to abut against the second torsion arm. Then, the second actuating element is installed back onto the connector, causing it to abut against the first torsion arm, thus achieving bidirectional resetting of the handle when unlocking in the second unlocking direction. This eliminates the need for the reset module to differentiate between left-opening and right-opening doors during production, allowing direct adaptation to all door types and improving the module's compatibility.

[0030] As an optional implementation, the snap-fit ​​portion is integrally disposed on the base. Along the axial direction of the rotating shaft, the snap-fit ​​portion extends from the side of the base toward the side closer to the second end. The snap-fit ​​portion is provided with a clearance opening, and the elastic reset member is configured to at least partially extend into the clearance opening to snap with the snap-fit ​​portion.

[0031] The locking portion extends axially from the side of the base towards the second end along the pivot axis, forming a longitudinally extending protruding structure. The locking portion also has a clearance opening, allowing the second torsion arm of the elastic reset member to partially extend into the clearance opening. This provides longitudinal support to the second torsion arm through the locking portion, restricting its circumferential movement.

[0032] In addition, by integrating the snap-fit ​​part into the base, the base can be manufactured using a stamping process. The snap-fit ​​part is formed by bending the sheet metal on the side of the base axially, and the clearance is stamped out simultaneously during the bending process. This eliminates the need for additional molds for secondary processing, thereby improving the production efficiency of the entire reset module and reducing production costs.

[0033] As an optional implementation, the reset module further includes a limiting member, wherein a surrounding recess is provided on the circumferential surface of the rotating shaft, the recess being located on the side of the base near the first end, the limiting member being at least partially disposed within the recess, and the limiting member being configured to abut against the base to restrict the position of the base along the axial direction of the rotating shaft; and / or,

[0034] The reset module also includes two gaskets, both of which are sleeved on the rotating shaft and abut against both sides of the base along the axial direction of the rotating shaft.

[0035] By providing a circumferential recess on the circumferential surface of the rotating shaft, with the recess located on the side of the base near the first end, and a limiting member at least partially disposed within the recess, the limiting member abutting against the base. Simultaneously, the connecting member and the elastic reset member are located on the side of the base near the second end, thereby axially clamping the base to limit its position along the axial direction of the rotating shaft. This prevents the base from shifting and causing a torsion arm jamming, thus ensuring the reset stability of the reset module.

[0036] There is friction between the base, the elastic reset component, and the limiting component. Over time, the film layer will cause wear on the contact surfaces. By setting gaskets on both sides of the base to isolate these contact surfaces, the service life of the base, the elastic reset component, and the limiting component can be improved, and the reset accuracy of the entire reset module can be avoided due to wear.

[0037] As an optional implementation, the second end of the rotating shaft is provided with two notches along the radial direction of the rotating shaft, and the two notches are arranged opposite each other along the radial direction of the rotating shaft. The connector is provided with a second shaft hole, and two locking pins are protruding on the inner wall of the second shaft hole. When the rotating shaft passes through the second shaft hole, the two locking pins are configured to be respectively engaged with the two notches.

[0038] Two notches on the rotating shaft are arranged radially opposite each other, and two locking pins are correspondingly positioned on the inner wall of the second shaft hole of the connector. This ensures that the locking pins are fully aligned with the notches, achieving a secure connection. This foolproof design makes the reset module assembly more intuitive, thereby improving assembly efficiency and accuracy.

[0039] Secondly, although the connector is fixedly connected to the rotating shaft, if the fixed connection between the connector and the rotating shaft becomes loose, it can be engaged in the notch by a locking pin, so that the rotating shaft forces the connector to rotate synchronously, avoiding relative free rotation between the two, thereby ensuring the stability of the reset module.

[0040] As an optional implementation, the rotating shaft includes a first shaft segment, a second shaft segment, and a third shaft segment connected sequentially from the first end to the second end. The outer diameters of the first shaft segment and the third shaft segment are the same, and the outer diameter of the second shaft segment is larger than that of the first shaft segment. The base is sleeved on the first shaft segment and abuts against the side of the second shaft segment near the first end. The connector is welded to the third shaft segment and abuts against the side of the second shaft segment near the second end. The elastic reset member is sleeved on the second shaft segment.

[0041] By making the outer diameter of the second shaft segment larger than that of the first and third shaft segments, two axial stepped surfaces are formed on both sides of the second shaft segment near the first and second ends. The base is fitted onto the first shaft segment and abuts against the stepped surface near the first end, thus restricting its movement towards the second end. The connector is welded to the third shaft segment and abuts against the stepped surface near the second end, thus restricting its movement towards the first end. This prevents the elastic reset component from being squeezed and deformed due to axial movement of the base and connector, or from the gap between the actuating component and the torsion arm becoming larger, thereby improving the stability of the reset function of the reset module.

[0042] Secondly, this utility model also discloses an intelligent door lock, including a handle, a front shell, a rear shell, and a reset module as described in the first aspect above;

[0043] The front shell is connected to the rear shell, and the front shell and the rear shell together define an installation space. The reset module is disposed in the installation space. The handle is located on the side of the front shell away from the installation space. The first end of the rotating shaft passes through the front shell to be connected to the handle. The reset module is connected to the rear shell.

[0044] The reset module allows for independent pre-installation and reset function testing before shipment. This means that when the reset module is installed in the smart lock's installation space, there is no need to adjust the position of the internal components of the reset module; only the operation of fixing the reset module to the back cover needs to be completed. This improves the assembly efficiency and accuracy of the entire smart lock assembly.

[0045] In addition, the front shell of a smart door lock usually needs to be equipped with modules such as fingerprint recognition. By installing the reset module in the rear shell, the layout of the entire installation space can be optimized, avoiding mutual interference between modules in the installation space, or stacking modules that would result in an excessively thick smart door lock.

[0046] The reset module allows for independent pre-installation and reset function testing before shipment. This means that when the reset module is installed in the smart lock's installation space, there is no need to adjust the position of the internal components of the reset module; only the operation of fixing the reset module to the back cover needs to be completed. This improves the assembly efficiency and accuracy of the entire smart lock assembly.

[0047] In addition, the front shell of a smart door lock usually needs to be equipped with modules such as fingerprint recognition. By installing the reset module in the rear shell, the layout of the entire installation space can be optimized, avoiding mutual interference between modules in the installation space, or stacking modules that would result in an excessively thick smart door lock.

[0048] As an optional implementation, the base is provided with a plurality of first mounting holes, and the rear shell is provided with a plurality of second mounting holes. The first mounting holes and the second mounting holes are configured to allow fasteners to pass through, so that the base is connected to the rear shell.

[0049] By providing multiple first mounting holes on the base and multiple second mounting holes on the rear shell, fasteners can be inserted through these holes to connect the base to the rear shell, thereby securing the reset module to the rear shell. This multi-hole fixing method improves the stability of the reset module.

[0050] Compared with the prior art, the beneficial effects of this application are:

[0051] This utility model provides a reset module and a smart door lock. A rotating shaft has a first end and a second end along its axial direction. The first end is connected to a handle, and the second end passes through a limiting hole in a base. The rotating shaft and the base are rotatably connected. A connecting member passes through the second end and is located on the side of the base away from the first end. The connecting member is connected to the rotating shaft, so that when the rotating shaft rotates, the connecting member can drive a toggle member extending from the connecting member towards the base to rotate. An elastic reset member is sleeved on the rotating shaft and located between the base and the connecting member. It is configured to engage with a snap-fit ​​part and is also configured to provide a reset force for the toggle member and the rotating shaft after the toggle member compresses the elastic reset member. This design provides a mounting base, with the rotating shaft and base forming a rotational fit through limiting holes, eliminating the need for external bearings or support structures. The elastic reset component achieves radial positioning by fitting onto the rotating shaft, circumferential positioning by engaging with the base's snap-fit ​​part, and axial clamping by the base and connecting parts. Furthermore, the connection between the connecting parts and the rotating shaft, as well as the transmission relationship between the actuating part and the elastic reset component, are all located within the reset module itself, requiring no external auxiliary structures. This allows the entire reset module to be pre-assembled as an independent module. During pre-assembly, specialized tooling can improve the assembly accuracy of the entire reset module, preventing reset jamming and reset failure. Attached Figure Description

Detailed Implementation

[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0071] In this application, the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0072] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0073] Furthermore, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0074] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0075] The handle reset module of a smart door lock is a core mechanical component that ensures the lock automatically returns to its original position after use, allowing for precise triggering of the next operation. The core of handle reset is the release of energy stored in the elastic element within the reset module after deformation, which drives the handle back to its initial position after operation.

[0076] The manufacturing processes for the lock face and reset component of smart door locks include die casting and stamping. Die casting involves filling a mold cavity with molten metal under high pressure to create the lock face and reset component. This process can form complex structures containing deep cavities, bosses, reinforcing ribs, and irregularly shaped holes in a single step, thus well-suited to the functional integration requirements of smart lock faces. Stamping, on the other hand, involves applying pressure to a metal sheet at room temperature using a mold, utilizing the sheet's ductility to cause plastic deformation or separation of the material, thereby creating the lock face and reset component. This process offers advantages such as low cost and high efficiency.

[0077] However, regardless of whether smart locks are manufactured using die-casting or stamping processes, they all employ a process of installing and resetting components (such as springs, connectors, and pivots) on-site one by one. This introduces errors at each assembly step, which, when accumulated, can lead to problems such as handle jamming or incomplete handle reset, negatively impacting the user experience.

[0078] In view of this, this application discloses a reset module, wherein the base is provided with a first shaft hole and a snap-fit ​​portion spaced apart. The rotating shaft has a first end and a second end along its axial direction. The first end is rotatably inserted through the first shaft hole to connect with a handle, and the second end is located on the side of the base opposite to the handle. A connector is fixedly sleeved on the second end, and the connector is provided with a toggle member protruding towards the base along the axial direction of the rotating shaft. An elastic reset member is sleeved on the second end and located between the base and the connector along the axial direction of the rotating shaft. It at least partially abuts against the toggle member and at least partially snaps into the snap-fit ​​portion. The connector can drive the toggle member to rotate when the rotating shaft rotates, thereby driving the elastic reset member to rotate and compress it. This allows the base to provide a mounting foundation, with the rotating shaft and base forming a rotational fit, eliminating the need for external bearings or support structures. The elastic reset member achieves radial positioning by being sleeved on the rotating shaft and circumferential positioning by snapping into the snap-fit ​​portion of the base. Furthermore, the connection between the connector and the rotating shaft, as well as the transmission relationship between the actuating component and the elastic reset component, are all completed within the reset module, eliminating the need for external auxiliary structures. This allows the entire reset module to be pre-assembled as an independent module, thereby improving the assembly accuracy of the entire reset module during the pre-assembly process and preventing reset jamming or failure during installation in a smart door lock.

[0079] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0080] The reset module 100 of this application is applied to the smart door lock 200 (e.g., Figure 14 and Figure 15 As shown, the smart door lock 200 includes a handle 201, which can be rotated to unlock the smart door lock 200.

The reset module 100 of this application includes a base 1, a rotating shaft 2, a connector 3, and an elastic reset member 4. The base 1 is provided with a first shaft hole 11 and a snap-fit ​​portion 12. The first shaft hole 11 is located in the middle of the base 1, and the snap-fit ​​portion 12 is located near the edge of the base 1 and is spaced apart from the first shaft hole 11. The rotating shaft 2 has a first end 21 and a second end 22 along its axial direction O. The first end 21 is configured to rotatably pass through the first shaft hole 11 to connect with the handle 201, and the second end 22 is located on the side of the base 1 opposite to the handle 201. The connector 3 is fixedly sleeved on the second end 22. The connector 3 is provided with a toggle member 31 protruding toward the base 1 along the axial direction O of the rotating shaft 2. The connector 3 is configured to drive the toggle member 31 to rotate when the rotating shaft 2 rotates. The elastic reset member 4 is sleeved on the second end 22 and is located along the axial direction O of the rotating shaft 2. The elastic reset member 4 is located between the base 1 and the connecting member 3. The elastic reset member 4 at least partially abuts against the actuating member 31 and at least partially engages with the locking part 12. The elastic reset member 4 is configured to rotate and generate torsional deformation under the drive of the actuating member 31 to provide a reset force for the actuating member 31 and the rotating shaft 2.

[0082] The reset module 100 of this application provides a unified installation reference through the base 1. The rotating shaft 2 forms a precise rotational fit with the base 1 through the first shaft hole 11, eliminating the need for additional bearings. The elastic reset member 4 achieves radial positioning by sleeved on the rotating shaft 2 and circumferential positioning by engaging with the snap-fit ​​part 12 of the base 1. Simultaneously, it is axially clamped by the base 1 and the connecting member 3, thereby enabling the pre-assembly of all components within the reset module 100. This allows the entire reset module 100 to be pre-assembled as an independent module, improving the assembly accuracy of the entire reset module 100 during pre-assembly and preventing reset jamming or failure when installed in the smart door lock 200.

[0083] Secondly, the reset module 100 can be manufactured separately, and the elastic reset member 4 inside the reset module 100 can rotate and be compressed under the drive of the actuating member 31 to provide the actuating member 31 and the rotating shaft 2 with the reset force. This allows the assembled reset module 100 to be tested for rotational reset before leaving the factory, so that the reset accuracy problem of the reset module 100 can be checked in time during the production process, thereby avoiding the situation of rework after the reset module 100 is installed in the smart door lock 200.

[0084] Furthermore, the base 1, connector 3, and other components in the reset module 100 of this application do not require the fabrication of complex deep cavities or positioning posts, and can therefore be manufactured using a stamping process, which helps reduce the production cost of the reset module 100. Moreover, the stamping process enables the rapid production of standardized components, thereby facilitating the rapid production of components such as the base 1, rotating shaft 2, and connector 3, which helps improve the production efficiency of the reset module 100.

[0085] It is understood that the base 1 can be a circular base, a square base, or a rectangular base, etc. In this embodiment, the base 1 is a rectangular base as an example. The length direction of the base 1 is the first direction X, and the width direction of the base 1 is the second direction Y, which will be explained later.

[0086] Optionally, the first shaft hole 11 is located in the middle of the base 1, and the snap-fit ​​part 12 can be located on the side of the base 1, so as to avoid mutual interference between the rotating shaft 2 and the snap-fit ​​part 12.

[0087] It is understood that the aforementioned connector 3 may be a connecting piece, a connecting plate, or a connecting block, and this embodiment does not specifically limit it.

[0088] It is understood that the aforementioned actuating element 31 can be a bolt, a pin, or a stamped boss that is directly integrally formed during the stamping of the connecting element 3. This embodiment does not specifically limit this.

[0089] It is understood that the aforementioned elastic reset element 4 can be a planar spiral spring or a torsion spring. Taking a planar spiral spring as an example, the inner end of the planar spiral spring is sleeved on the second end 22 of the rotating shaft 2 and fixedly connected to the base 1, and the outer end is snapped into the snap-fit ​​part 12 of the base 1. The actuating element 31 abuts against the outer end of the planar spiral spring, so that the rotating shaft 2 can rotate to drive the actuating element 31 to rotate, thereby driving the outer end of the planar spiral spring to rotate, so that the planar spiral spring will undergo torsional deformation.

[0090] It is understood that the torsional deformation of the elastic reset member 4 specifically refers to the deformation of the elastic reset member 4 along the circumferential direction of the rotating shaft 2, that is, the elastic reset member 4 torsional along the circumferential direction of the rotating shaft 2, thereby allowing the elastic reset member 4 to store energy to provide the resetting force for the toggle member 31 and the rotating shaft 2.

[0091] The following explanation will take the elastic reset element 4 as an example of a torsion spring.

[0092] Optionally, please refer to Figure 5The elastic reset member 4 includes a main body 41, a first torsion arm 42, and a second torsion arm 43. The main body 41 is sleeved on the rotating shaft 2. Along the radial direction of the rotating shaft 2, both the first torsion arm 42 and the second torsion arm 43 extend from the main body 41 in a direction away from the rotating shaft 2. The second torsion arm 43 is disposed opposite to the first torsion arm 42 along the radial direction of the rotating shaft 2. The second torsion arm 43 is engaged with the engaging portion 12. A actuating member 31 is disposed below the second torsion arm 43 and abuts against the second torsion arm 43. The actuating member 31 is configured to drive the second torsion arm 43 to rotate along a first rotation direction A when the rotating shaft 2 rotates, thereby compressing the elastic reset member 4.

[0093] The main body 41 of the torsion spring is sleeved on the rotating shaft 2, and the first torsion arm 42 and the second torsion arm 43 extend in the radial direction of the rotating shaft 2. This allows the elastic reset member 4 to be completely accommodated in the axial space between the base 1 and the connecting member 3. This eliminates the need for an external structure of the reset module 100 to support the elastic reset member 4, thus enabling the entire reset module 100 to be assembled and manufactured independently and subjected to reset testing.

[0094] It is understood that the first torsion arm 42 can be fixedly connected to the base 1, so that when the second torsion arm 43 rotates along the first rotation direction A, the position of the first torsion arm 42 is fixed, thereby compressing the elastic reset member 4 to provide rotational reset force to the handle 201.

[0095] It can be understood that the snap-fit ​​part 12 can be disposed on one side of the base 1 along the first direction X, so that the first torsion arm 42 and the second torsion arm 43 are disposed opposite to each other along the first direction X. In the initial relaxed state of the elastic member, the second torsion arm 43 extends along the first direction X. At this time, the second torsion arm 43 can be positioned by gravity, so that the second torsion arm 43 can be connected to the snap-fit ​​part 12 without additional calibration, thereby improving the assembly efficiency of the reset module 100.

[0096] Please see Figure 5 and Figure 6 , Figure 6 This is a schematic diagram of the snap-fit ​​portion disclosed in an embodiment of this application. In some embodiments, the snap-fit ​​portion 12 is integrally disposed on the base 1, along the axial direction O of the rotating shaft 2, and extends from the side of the base 1 toward the side near the second end 22. The snap-fit ​​portion 12 is provided with a relief opening 121, and the elastic reset member 4 is configured to at least partially extend into the relief opening 121 to snap with the snap-fit ​​portion 12.

[0097] The locking part 12 extends axially from the side of the base 1 to the second end 22 along the rotating shaft 2, forming a longitudinally extending protruding structure. The locking part 12 is provided with a relief opening 121, so that the second torsion arm 43 of the elastic reset member 4 can partially extend into the relief opening 121. In this way, the locking part 12 can provide longitudinal support for the second torsion arm 43 and limit its circumferential movement.

[0098] In addition, since the snap-fit ​​part 12 is integrally set on the base 1, the base 1 can be manufactured by stamping. The snap-fit ​​part 12 can be formed by bending the plate on the side of the base 1 axially. At the same time, the clearance opening 121 is stamped out during the bending process. This eliminates the need for additional molds for secondary processing, thereby improving the production efficiency of the entire reset module 100 and reducing production costs.

[0099] It is understandable that the opening direction of the aforementioned clearance opening 121 should be set upward, for example, in a U-shape, so that the second torsion arm 43 can naturally fall into the clearance opening 121 under its own gravity without the need for manual adjustment of its position.

[0100] Rotating handle 201 can both unlock and lock the door. For example, rotating handle 201 downwards unlocks the door, and rotating it upwards locks it. This requires a reset module 100 to enable both bidirectional rotation and bidirectional reset of handle 201. Please continue reading. Figure 5 and Figure 6 The locking part 12 includes two parts, which are arranged opposite each other along the radial direction of the rotating shaft 2. The first torsion arm 42 and the second torsion arm 43 are respectively locked into the two locking parts 12. The actuating member 31 includes two parts, namely the first actuating member 311 and the second actuating member 312, which are arranged opposite each other along the radial direction of the rotating shaft 2. The first actuating member 311 and the second actuating member 312 are spaced apart from the base 1 along the axial direction O of the rotating shaft 2. The first actuating member 311 is located below the first torsion arm 42 and abuts against the first torsion arm 42. The second actuating member 312 is located below the second torsion arm 43 (e.g., Figure 6 The second actuating member 312 abuts against the second torsion arm 43. When the shaft 2 is configured to rotate in the first rotation direction A, the second actuating member 312 drives the second torsion arm 43 to rotate and compress the main body 41, so that the second torsion arm 43 and the main body 41 provide a resetting force for the second actuating member 312 and the shaft 2. The shaft 2 is also configured to rotate in the second rotation direction B, so that the first actuating member 311 drives the first torsion arm 42 to rotate and compress the main body 41, so that the first torsion arm 42 and the main body 41 provide a resetting force for the first actuating member 311 and the shaft 2.

[0101] Two locking portions 12 are arranged radially opposite each other along the rotating shaft 2. A first torsion arm 42 and a second torsion arm 43 are respectively locked into the two locking portions 12. A first actuating member 311 abuts against the lower part of the first torsion arm 42. When the rotating shaft 2 rotates along the first rotation direction A, the second actuating member 312 can drive the second torsion arm 43 to rotate and compress the main body 41, so that the second torsion arm 43 and the main body 41 provide a resetting force for the second actuating member 312 and the rotating shaft 2. Thus, when the handle 201 rotates along the first rotation direction A, the second actuating member 312 can drive the second torsion arm 43 to rotate and compress the main body 41, thereby providing a resetting force for the second actuating member 312 and the rotating shaft 2. Furthermore, when the rotating shaft 2 rotates along the second rotation direction B, the first actuating member 311 can drive the first torsion arm 42 to rotate and compress the main body 41, so that the first torsion arm 42 and the main body 41 provide a resetting force for the first actuating member 311 and the rotating shaft 2. When the handle 201 rotates along the second rotation direction B, the first actuating element 311 drives the first torsion arm 42 to rotate, compressing the main body 41, thereby providing a force for the first actuating element 311 and the rotating shaft 2 to reset. Simultaneously, the second rotation direction B is opposite to the first rotation direction A. Thus, whether the handle 201 rotates along the first rotation direction A or the second rotation direction B (for example, the first rotation direction A is downward rotation of the handle 201, and the second rotation direction B is upward rotation of the handle 201), releasing the handle 201 will always provide a reset force through the elastic reset element 4, allowing the actuating element and the rotating shaft 2 to reset. This eliminates the need for two separate reset modules 100 for unlocking and locking the same handle 201, thereby improving the adaptability of the reset module 100 and reducing its cost.

[0102] It is understandable that the first torsion arm 42 and the second torsion arm 43 can be spaced apart along the first direction X, and correspondingly, the first latching part 12 and the second latching part 12 are also spaced apart along the first direction X.

[0103] It is understandable that either the first rotation direction A or the second rotation direction B can be clockwise or counterclockwise, and the rotation angle of the first rotation direction A and the second rotation direction B can be within the range of 0° to 90°, for example, 10°, 26°, 45°, 72° or 90°, which can be set according to the actual use.

[0104] To accommodate different door positions, handle 201 typically comes in two forms: left-opening and right-opening. In both left-opening and right-opening configurations, the unlocking direction of handle 201 is completely opposite. Therefore, in order for the reset module 100 to provide reset force for handle 201 in both left-opening and right-opening configurations, the reset module 100 needs to provide opposite reset forces. Please refer to [link / reference]. Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the reset module for the handle in the first unlocking direction. Figure 8 This is a schematic diagram of the reset module of the handle in the second unlocking direction. The first actuating element 311 is welded to the connecting element 3, and the second actuating element 312 is detachably connected to the connecting element 3. The handle 201 has a first unlocking direction C and a second unlocking direction D. When the handle 201 is unlocked along the first unlocking direction C, the first actuating element 311 abuts against the first torsion arm 42, and the second actuating element 312 abuts against the second torsion arm 43. When the handle 201 is unlocked along the second unlocking direction D, the first actuating element 311 abuts against the second torsion arm 43, and the second actuating element 312 abuts against the first torsion arm 42. When the handle 201 switches between the first unlocking direction C and the second unlocking direction D, the second actuating element 312 separates from the connecting element 3, causing the handle 201 to drive the rotating shaft 2 and the first actuating element 311 to rotate, so that the first actuating element 311 abuts against the second torsion arm 43, and the second actuating element 312 is configured to abut against the first torsion arm 42 when installed on the connecting element 3.

[0105] The handle 201 is detachably connected to the connector 3 via the second actuating member 312. The handle 201 has opposite first unlocking direction C and second unlocking direction D. When the handle 201 is operated in the first unlocking direction C (e.g., right-hand opening), the first actuating member 311 abuts against the first torsion arm 42 and the second actuating member 312 abuts against the second torsion arm 43, thereby realizing the bidirectional reset of the handle 201 when it is unlocked in the first unlocking direction C. When it is necessary to switch the unlocking direction of handle 201 from the first unlocking direction C to the second unlocking direction D (e.g., left-opening), the second actuating member 312 can be removed. By rotating handle 201, the rotating shaft 2 and the first actuating member 311 will rotate together, causing the first actuating member 311 to abut against the second torsion arm 43. Then, the second actuating member 312 will be installed on the connecting member 3, so that the second actuating member 312 abuts against the first torsion arm 42. This achieves bidirectional reset of handle 201 when it is unlocked along the second unlocking direction D. This eliminates the need for the reset module 100 to distinguish between left-opening and right-opening doors during production, allowing it to directly adapt to all door types and improving the adaptability of the reset module 100.

[0106] In addition, the second toggle member 312 of the reset module 100 is detachably connected to the connector 3, so that the reset module 100 can be adapted to the left-opening and right-opening of the smart door lock 200. Moreover, the reset module 100 can be manufactured and assembled independently, so that the reversal adjustment of the reset module 100 can be quickly realized during on-site installation without returning it to the factory for reassembly, thereby helping to improve installation efficiency.

[0107] It is understood that, in order to enable the second actuating element 312 to be detachably connected to the connecting element 3, the second actuating element 312 can be a bolt or a pin, etc., and this embodiment does not make specific limitations on this.

[0108] It is understandable that both the first unlocking direction C and the second unlocking direction D should include the range of 180° rotation of the handle. Both the first unlocking direction C and the second unlocking direction D should include a first rotation direction A and a second rotation direction B. For example, if the first unlocking direction C is to open the handle 201 to the left, then the handle 201 includes the first rotation direction A, such as turning downwards to unlock the handle 201, and also includes the second rotation direction B, such as turning upwards to lock the handle 201.

[0109] It is understandable that, since both the first actuating element 311 and the second actuating element 312 are located below the first torsion arm 42 or the second torsion arm 43 (e.g., Figure 7 (in the lower part of the vertical direction of the paper), and the first actuating member 311 and the second actuating member 312 are engaged in the engaging part 12. Therefore, when switching the first unlocking direction C and the second unlocking direction D of the handle 201, after the second actuating member 312 is removed from the connecting member 3, the handle 201 needs to rotate 180° around the lower part. This is so that the first actuating member 311 can be switched from the state of abutting against the first torsion arm 42 to the state of abutting against the second torsion arm 43 without being blocked.

[0110] Please see Figures 9 to 12 , Figure 9 This is a schematic diagram of the structure of the rotating shaft disclosed in the embodiments of this application. Figure 10 This is a schematic diagram of the reset module disclosed in the embodiments of this application from another perspective. Figure 11 yes Figure 10 Cross-sectional view at the FF point. Figure 12 yes Figure 11 A partial enlarged view of point G. In some embodiments, the reset module 100 further includes a limiting member 5. A recess 231 is provided around the circumference of the rotating shaft 2. The recess 231 is located on the side of the base 1 near the first end 21. The limiting member 5 is at least partially disposed in the recess 231 and is configured to abut against the base 1 to limit the position of the base 1 in the axial direction O of the rotating shaft 2.

[0111] By providing a surrounding recess 231 on the circumferential surface of the rotating shaft 2, with the recess 231 located on the side of the base 1 near the first end 21, and the limiting member 5 at least partially disposed within the recess 231, and the limiting member 5 abutting against the base 1. Simultaneously, the connecting member 3 and the elastic reset member 4 are located on the side of the base 1 near the second end 22, thereby forming an axial clamp on the base 1 to limit its position along the axial direction O of the rotating shaft 2, thus preventing the base 1 from shifting and causing a torsion arm jamming situation, thereby ensuring the reset stability of the reset module 100.

[0112] Secondly, the limiting member 5 is at least partially disposed in the recessed portion 231 surrounding the circumference of the rotating shaft 2, and the limiting member 5 abuts against the base 1. In this way, the interference fit between the limiting member 5 and the recessed portion 231 of the rotating shaft 2 makes it difficult for the limiting member 5 to fall off after being installed in the recessed portion 231.

[0113] In addition, the recessed portion 231 is arranged around the rotating shaft 2, so that it can be manufactured simultaneously by stamping process without secondary processing, thereby helping to reduce the manufacturing cost of the entire reset module 100.

[0114] It is understood that the aforementioned limiting member 5 may be an E-type snap ring or a shaft retaining ring, etc., and this embodiment does not specifically limit it.

[0115] Optionally, please refer to Figure 12 and Figure 13 , Figure 12 This is a schematic diagram of the structure of the notch and the locking post disclosed in the embodiments of this application. Figure 13 This is a schematic diagram of the notch and locking pin structure disclosed in the embodiments of this application. The reset module 100 also includes two gaskets 6, both of which are sleeved on the rotating shaft 2 along the axial direction O of the rotating shaft 2, and the two gaskets 6 respectively abut against the two sides of the base 1.

[0116] There is friction between the base 1, the elastic reset member 4, and the limiting member 5. Over time, the film layer will cause wear on the contact surface. By setting gaskets 6 on both sides of the base 1 to isolate these contact surfaces, the service life of the base 1, the elastic reset member 4, and the limiting member 5 can be improved, and the reset accuracy of the entire reset module 100 can be avoided due to wear.

[0117] In addition, by setting the shim 6, the axial impact generated by the door closing vibration or the forceful operation of the handle 201 in the reset module 100 can be absorbed, so as to avoid affecting the reset accuracy of the reset module 100.

[0118] It is understood that the gasket 6 mentioned above can be a metal gasket, such as phosphor bronze, or a plastic gasket, such as polyoxymethylene. This embodiment does not specifically limit the type of gasket.

[0119] In some embodiments, the second end 22 of the rotating shaft 2 is provided with two notches 251 along the radial direction of the rotating shaft 2. The two notches 251 are arranged opposite to each other along the radial direction of the rotating shaft 2. The connector 3 is provided with a second shaft hole 33. Two locking pins 331 protrude from the inner wall of the second shaft hole 33. When the rotating shaft 2 passes through the second shaft hole 33, the two locking pins 331 are configured to be respectively locked into the two notches 251.

[0120] Two notches 251 on the rotating shaft 2 are arranged radially opposite each other, and two locking posts 331 are correspondingly located on the inner wall of the second shaft hole 33 of the connector 3. This ensures that the locking posts 331 can only be engaged and fixed when they are fully aligned with the notches 251. This foolproof design makes the resetting module 100 more intuitive to assemble, thereby improving the assembly efficiency and accuracy of the resetting module 100.

[0121] Secondly, although the connector 3 is fixedly connected to the rotating shaft 2, if the fixed connection between the connector 3 and the rotating shaft 2 becomes loose, it can be engaged in the notch 251 by the locking pin 331, so that the rotating shaft 2 can force the connector 3 to rotate synchronously, avoiding the two from rotating relative to each other, thereby ensuring the stability of the reset module 100.

[0122] Optionally, the two notches 251 are arranged opposite each other along the second direction Y. This way, on the one hand, the torsion arm and the locking part 12 are arranged opposite each other along the first direction X, and the two notches 251 and the two locking pins 331 are arranged opposite each other along the second direction Y, which can avoid affecting the normal use of other components in the reset module 100. On the other hand, when the handle 201 is rotated, the first actuating member 311 and the second actuating member 312 are arranged opposite each other along the first direction X, and the two locking pins 331 are arranged opposite each other along the second direction Y. The first direction X and the second direction Y are perpendicular, which can balance the force on the connecting member 3.

[0123] It is understood that the two card posts 331 mentioned above can be square card posts, rectangular card posts, or cylindrical card posts, etc., and the shape of the corresponding notch can also be a square notch, a rectangular notch 251, or a cylindrical notch, etc. This implementation does not make specific limitations in this regard.

[0124] Alternatively, please continue reading Figures 9 to 12 The rotating shaft 2, extending from the first end 21 to the second end 22, comprises a first shaft segment 23, a second shaft segment 24, and a third shaft segment 25 connected sequentially. The first shaft segment 23 and the third shaft segment 25 have the same outer diameter, while the outer diameter of the second shaft segment 24 is larger than that of the first shaft segment 23. A base 1 is fitted onto the first shaft segment 23 and abuts against the side of the second shaft segment 24 near the first end 21. A connecting member 3 is welded to the third shaft segment 25 and abuts against the side of the second shaft segment 24 near the second end 22. An elastic reset member 4 is fitted onto the second shaft segment 24.

[0125] By having the outer diameter of the second shaft segment 24 larger than that of the first shaft segment 23 and the third shaft segment 25, two axial stepped surfaces are formed on both sides of the second shaft segment 24 near the first end 21 and near the second end 22. The base 1 is fitted onto the first shaft segment 23 and abuts against the stepped surface near the first end 21, thus restricting its movement toward the second end 22. The connector 3 is welded to the third shaft segment 25 and abuts against the stepped surface near the second end 22, thus restricting its movement toward the first end 21. This prevents the elastic reset member 4 from being squeezed and deformed due to upward movement of the base 1 and the connector 3 in the axial direction O, or from the gap between the actuating member and the torsion arm becoming larger, thereby improving the stability of the reset function of the reset module 100.

[0126] Please see Figure 14 and Figure 15 , Figure 14 This is a schematic diagram of the structure of the smart door lock disclosed in the embodiments of this application. Figure 15 This is an exploded view of the smart door lock disclosed in the embodiments of this application. In a second aspect, this application discloses a smart door lock 200, including a handle 201, a front shell (not shown in the figure), a rear shell 202, and a reset module 100 as described in the first aspect above. The front shell and the rear shell 202 are connected, and the front shell and the rear shell 202 together define an installation space 203. The reset module 100 is disposed in the installation space 203. The handle 201 is located on the side of the front shell opposite to the installation space 203. The first end 21 of the rotating shaft 2 passes through the front shell to connect with the handle 201. The reset module 100 is connected to the rear shell 202.

[0127] The reset module 100 allows for independent pre-installation and reset function testing before shipment. This means that when the reset module 100 is installed in the installation space 203 of the smart lock 200, there is no need to adjust the position of the internal components of the reset module 100. The only requirement is to fix the reset module 100 to the rear shell 202. This improves the assembly efficiency and accuracy of the entire smart lock 200.

[0128] In addition, the front shell of the smart door lock 200 usually needs to install modules such as fingerprint recognition. By installing the reset module 100 to the rear shell 202, the layout of the entire installation space 203 can be optimized, avoiding mutual interference between modules in the installation space 203, or stacking causing the entire smart door lock 200 to be too thick.

[0129] Optionally, the base 1 is provided with a plurality of first mounting holes 13, and the rear shell 202 is provided with a plurality of second mounting holes 202a. The first mounting holes 13 and the second mounting holes 202a are configured to allow fasteners 204 to pass through, so that the base 1 is connected to the rear shell 202.

[0130] By providing multiple first mounting holes 13 on the base 1 and multiple second mounting holes 202a on the rear shell 202, and by having fasteners 204 pass through the first mounting holes 13 and the second mounting holes 202a, the base 1 can be connected to the rear shell 202, thereby fixing the reset module 100 to the rear shell 202. This multi-hole fixing method improves the stability of the reset module 100.

[0131] It is understood that the fastener 204 can be a self-tapping screw or a machine screw, and the corresponding first mounting hole 13 and second mounting hole 202a can be a threadless through hole or a threaded hole, etc. This embodiment does not make specific limitations on this.

[0132] It is understandable that multiple first mounting holes 13 can be located on the side or at the four corners of the base 1 to avoid affecting other components in the reset module 100.

[0133] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
