The first end is rotatably arranged in the first shaft hole to be connected to the handle. The second end is located on the side of the base away from the handle. The connecting piece is sleeved on the second end and located in the first mounting space of the base. The connecting piece is provided with a pushing piece protruding towards the base in the axial direction of the rotating shaft, so that the rotation can drive the pushing piece to rotate.

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] Smart door locks, integrating intelligent functions such as fingerprint recognition, password verification, and remote control, have been widely used in homes, offices, and commercial spaces, becoming a core product for enhancing access security and convenience. The proper use of a smart door lock relies on the flexible rotation and automatic reset of the handle. After the user unlocks or locks the door by turning the handle, the handle must return to its initial position under the action of the reset module to ensure reusability. Therefore, the reset module in the handle is a crucial component ensuring stable operation.

[0003] In related technologies, the reset module is usually sleeved on the rotating shaft and fixed on the base. However, it is usually directly exposed on the surface of the base without a dedicated installation space for isolation. As a result, dust, moisture and other substances can enter the reset module during use, causing moisture corrosion and dust wear on the components, thus affecting the service life of the reset mechanism. Utility Model Content

[0004] This utility model discloses a reset module and a smart door lock, which can reduce or block external contaminants from entering the reset module and improve the service life of the reset module.

[0005] To achieve the above objectives, the first aspect of this utility model discloses a reset module, comprising: A base, the base forming a first mounting space with an opening, the base having a first shaft hole and an abutment portion, the first shaft hole communicating with the first mounting space, the first shaft hole being located in the middle of the base, and the abutment portion being located at the edge of the base; A pivot having a first end and a second end along its axial direction, the first end being configured to rotatably pass through a first shaft hole for connection with the handle, and the second end being at least partially located in the first mounting space; A connector, sleeved on the second end and located in the first mounting space, the connector having a protruding actuating element protruding from the side opposite to the base opening along the axial direction of the rotating shaft, the connector being configured to rotate with the rotating shaft to drive the actuating element to rotate; and, 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 abuts against the abutting 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.

[0006] The reset module of this application forms a first installation space with an opening through the base, thereby enabling both the connector and the elastic reset component to be installed in the first installation space of the base. That is, on the one hand, the base can provide a unified installation reference, and on the other hand, the base can protect the components in the first installation space, preventing external contaminants from entering the reset module and affecting the normal rotation and reset of the handle, thereby improving the service life of the reset module.

[0007] Based on this, the rotating shaft of this application 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 abutting against the base. Simultaneously, it is axially clamped by the base and connecting component, thus enabling the pre-assembly of all components within the entire reset module. This allows the entire reset module to be pre-assembled as an independent module, thereby improving the assembly accuracy during pre-assembly and preventing reset jamming or failure when installed in a smart lock.

[0008] As an optional implementation, the reset module further includes: A limiting component is sleeved on the second end and located in the first mounting space. Along the axial direction of the rotating shaft, the limiting component is configured to clamp the first plate portion to limit the position of the first plate portion on the rotating shaft.

[0009] The limiting component is located in the first installation space and sleeved on the second end of the rotating shaft. This allows the first plate to be clamped along the axial direction of the rotating shaft, thereby precisely limiting the axial position of the first plate on the rotating shaft. This, in turn, limits the axial position of the entire base on the rotating shaft, preventing the base from shifting in the axial direction during use. This ensures the relative position stability of the base, rotating shaft, connecting parts, and elastic reset parts, allowing the entire reset module to operate smoothly.

[0010] In addition, by using a limiting component to restrict the axial position of the base on the rotating shaft, it is not necessary to directly fix the base to the rotating shaft, making it easier to operate when the rotating shaft needs to be disassembled and replaced.

[0011] As an optional implementation, the limiting component includes a first limiting member and a second limiting member. Along the axial direction of the rotating shaft, the first limiting member is disposed between the connecting member and the first plate portion, and the first limiting member abuts against both the connecting member and the first plate portion. The elastic reset member is sleeved on the first limiting member. A circumferential recess is provided on the circumferential surface of the rotating shaft. The recess is located on the side of the connecting member near the second end. The second limiting member is disposed in the recess and abuts against the connecting member. The first limiting member and the second limiting member are configured to jointly limit the position of the first plate portion along the axial direction of the rotating shaft.

[0012] The first limiting member is located between the connecting member and the first plate and abuts against both. The second limiting member is located in the recess of the rotating shaft and abuts against the connecting member. This allows the first and second limiting members to form a bidirectional clamping positioning structure. This restricts the displacement of the first plate from both directions along the axial direction of the rotating shaft, resulting in higher positioning accuracy. It can prevent axial movement of the base caused by vibration, stress, or other factors, and ensure the stability of the relative positions of each component.

[0013] As an optional implementation, the base includes a first plate portion and a second plate portion. The first plate portion has a first shaft hole, and the opening of the first mounting space is away from the first plate portion along the axial direction of the rotating shaft. The second plate portion surrounds and connects to the edge of the first plate portion. The second plate portion and the first plate portion together form the first mounting space. The abutment portion is integrally disposed on the second plate portion. Along the radial direction of the rotating shaft, the abutment portion extends from the second plate portion toward one end close to the rotating shaft. The elastic reset member is configured to abut against the abutment portion.

[0014] The base includes a first plate and a second plate. The first plate surrounds the edge of the base, and the opening of the first mounting space faces away from the first plate along the axial direction of the rotating shaft. This allows the connector and the elastic reset component to be inserted into the first mounting space within the base through the opening, reducing the installation difficulty of the reset module. Furthermore, when maintenance or replacement of reset module components is required, disassembly and operation can be easily performed through the opening, thereby reducing the maintenance cost and difficulty of the reset module.

[0015] As an optional implementation, the elastic reset member includes: The main body is sleeved on the rotating shaft; First torsion arm; 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 each other along the radial direction of the rotating shaft. The first torsion arm is connected to the base, and the second torsion arm abuts against the abutting 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 undergoes torsional deformation.

[0016] By fitting the main body of the torsion spring onto the rotating shaft, and with the first and second torsion arms extending radially along the shaft, the elastic reset component can be fully accommodated within the axial space between the base and the connector. This eliminates the need for an external structure to support the elastic reset component, allowing the entire reset module to be assembled, manufactured, and tested independently.

[0017] As an optional implementation, the abutting part includes two abutting parts, 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 respectively abut against the corresponding abutting part; 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. 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; 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 in the second rotation direction, the first actuating member drives the first torsion arm to rotate and compresses the main body, so that the first torsion arm and the main body provide the first actuating member and the rotating shaft with a resetting force; The second rotation direction is opposite to the first rotation direction.

[0018] Two abutment portions are radially opposite to each other along the rotating shaft. A first torsion arm and a second torsion arm abut against the two abutment portions respectively. 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 drives the second torsion arm to rotate, causing torsional deformation of the main body, thus providing a resetting force for the second actuating member and the rotating shaft. Similarly, when the handle rotates in the first rotation direction, the second actuating member drives the second torsion arm to rotate, causing torsional deformation of 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 drives the first torsion arm to rotate, causing torsional deformation of the main body, thus providing a resetting force for the first actuating member and the rotating shaft. Similarly, when the handle rotates in the second rotation direction, the first actuating member drives the first torsion arm to rotate, causing torsional deformation of the main body, thereby providing a resetting force for the first actuating member and the rotating shaft. 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.

[0019] As an optional implementation, the abutting part includes two abutting parts, 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 respectively abut against the corresponding abutting part; 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 both the first actuating element and the second actuating element are spaced apart from the base in the axial direction of the rotating shaft. In the axial direction of the rotating shaft, the first actuating element extends from the side of the connecting member toward the side closer to the first end, and the first actuating element is fixedly connected to the connecting member, while the second actuating element is detachably connected to the connecting member. 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. 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; The first unlocking direction and the second unlocking direction are opposite.

[0020] 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.

[0021] As an alternative implementation, at least a portion of the connector is bent from the edge of the connector toward the first end to form the first actuating member.

[0022] This improves the overall rigidity of the actuating and connecting parts, resulting in higher structural reliability and a shorter production cycle.

[0023] 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; The front shell is connected to the rear shell, and the front shell and the rear shell together define a second mounting space. The reset module is disposed in the second mounting space. The handle is located on the side of the front shell away from the second mounting space. The first end of the rotating shaft passes through the front shell to connect with the handle. The reset module is connected to the rear shell so that the rear shell covers the opening of the base.

[0024] 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 second installation space of the smart lock, 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 can improve the assembly efficiency and accuracy of the entire smart lock.

[0025] As an optional implementation, the base includes a plurality of fixing parts. Along the radial direction of the rotating shaft, the plurality of fixing parts are located at the edge of the base, and along the axial direction of the rotating shaft, the fixing parts are disposed on the side of the base near the second end. The fixing parts are provided with a first mounting hole, and the rear shell is provided with a plurality of second mounting holes. The first mounting hole and the second mounting hole are provided in a one-to-one correspondence. The first mounting hole and the second mounting hole are configured to allow fasteners to pass through, so that the base is connected to the rear shell.

[0026] The base includes multiple fixing parts located at the edge of the base along the radial direction of the rotation axis. Each fixing part has a first mounting hole, and the rear shell has a corresponding second mounting hole. Fasteners pass through the first and second mounting holes, thus connecting the base to the rear shell. This multi-point support structure, formed by the multiple fixing parts, evenly distributes the force borne by the reset module during operation across multiple points on the rear shell, preventing localized stress concentration that could lead to loose connections or deformation of the rear shell.

[0027] Compared with the prior art, the beneficial effects of this application are: This utility model provides a reset module and a smart door lock. The rotating shaft has a first end and a second end along its axial direction. The first end is rotatably inserted through a first shaft hole to connect to a handle. The second end is located on the side of the base away from the handle. A connecting member is sleeved on the second end and located within a first mounting space of the base. The connecting member has a toggle member protruding towards the base along the axial direction of the rotating shaft, allowing rotation to drive the toggle member to rotate. An elastic reset member is sleeved on the second end and located between the base and the connecting member. At least part of the elastic reset member abuts against the toggle member, and at least part of the elastic reset member abuts against the abutting part. The elastic reset member rotates under the action of the toggle member and undergoes torsional deformation to provide a reset force for the toggle member and the rotating shaft. This provides a mounting base through the base, ensuring that both the connecting member and the elastic reset member are located within the first mounting space of the base. This protects the components within the first mounting space, preventing external contaminants from entering the reset module and affecting the normal rotation and reset of the handle, thereby improving the service life of the reset module.

Detailed Implementation

[0031] 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.

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.

[0034] Furthermore, the terms "setup" and "connection" should be interpreted broadly.

[0036] Smart door locks, which integrate intelligent functions such as fingerprint recognition, password verification, and remote control, have been widely used in homes, offices, and commercial venues, becoming a core product for improving the security and convenience of entrances and exits.

[0037] 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. After the user unlocks or locks the door by turning the handle, the handle releases energy stored in the elastic element within the reset module through deformation, driving the handle back to its initial position.

[0038] In related technologies, the reset module is usually sleeved on the rotating shaft and fixed on the base. However, it is usually directly exposed on the surface of the base without a dedicated installation space for isolation. As a result, dust, moisture and other substances can enter the reset module during use, causing moisture corrosion and dust wear on the components, thus shortening the service life of the reset mechanism. In view of this, this application discloses a reset module, wherein a base has a first shaft hole located in its middle and an abutment portion located at its edge, and the base forms a first mounting space with an opening, the first mounting space communicating with the first shaft hole. A rotating shaft has a first end and a second end along its axial direction, the first end rotatably passing through the first shaft hole to connect with a handle, and the second end at least partially located in the first mounting space. A connector is sleeved on the second end and located in the first mounting space, the connector having a toggle member protruding from the side opposite to the opening of 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, at least partially abutting against the toggle member and at least partially abutting against the abutment portion. The connector can drive the toggle member to rotate when the rotating shaft rotates, thereby driving the elastic reset member to rotate, causing the elastic reset member to undergo torsional deformation, thereby providing a reset force for the toggle member and the rotating shaft. This allows the base to provide an installation foundation, ensuring that both the connector and the elastic reset component are located within the first installation space of the base. This protects the components within the first installation space from external contaminants entering the reset module and affecting the normal rotation and reset of the handle, thereby extending the service life of the reset module.

[0039] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0040] The reset module 100 of this application is used in the smart door lock 200 (e.g., Figure 16 and Figure 17 As shown, the smart door lock 200 includes a handle 201, which can be rotated to unlock the smart door lock 200.

[0041] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the reset module disclosed in an embodiment of this application from one perspective. Figure 2 This is an exploded view of the reset module disclosed in the embodiments of this application. Figure 3 This is a schematic diagram of the reset module disclosed in an embodiment of this application from another perspective. Figure 4 yes Figure 3 A cross-sectional view at EE. 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 forms a first mounting space 11 with an opening. The base 1 has a first shaft hole 121 and an abutment portion 131. The first shaft hole 121 communicates with the first mounting space 11 and is located in the middle of the base 1. The abutment portion 131 is located at the edge of the base 1. 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 121 to connect with a handle 201. The second end 22 is at least partially located in the first mounting space 11. The connector 3 is sleeved on the second end 22 and is located in the first mounting space 11. The connector 3 has a toggle member 31 protruding from the side opposite to the opening of the base 1 along the axial direction O of the rotating shaft 2. The connector 3 is configured to rotate with the rotating shaft 2 when the rotating shaft 2 rotates to drive the toggle member 31 to rotate. 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 abuts against the abutting part 131. 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.

[0042] The reset module 100 of this application can provide a unified installation reference through the base 1, so that the connector 3 and the elastic reset member 4 are both located in the first installation space 11 of the base 1. In this way, the base 1 can protect the components in the first installation space 11, preventing external contaminants from entering the interior of the reset module 100 and affecting the normal rotation and reset of the handle 201, thereby improving the service life of the reset module 100.

[0043] Secondly, the rotating shaft 2 of the reset module 100 forms a precise rotational fit with the base 1 through the first shaft hole 121, eliminating the need for additional bearings. The elastic reset member 4 is radially positioned by sleeved on the rotating shaft 2 and circumferentially positioned by engaging with the abutment part 131 of the base 1. It is also axially clamped by the base 1 and the connecting member 3. Furthermore, both the connecting member 3 and the elastic reset member 4 are located within the first mounting space 11 of the base 1. This allows all components within the reset module 100 to be pre-assembled within the module, and the base 1 provides protection for the portion within the first mounting space 11. This enables the entire reset module 100 to be pre-assembled as an independent module, improving assembly accuracy during pre-assembly and preventing reset jamming or failure when installed in the smart door lock 200.

[0044] In addition, 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. Meanwhile, components such as the base 1 and connector 3 in the reset module 100 of this application do not require the fabrication of complex deep cavities and positioning posts, and can therefore be manufactured using a stamping process, which helps reduce the production cost of the reset module 100. Furthermore, the stamping process enables the rapid production of standardized components, thereby quickly producing components such as the base 1, rotating shaft 2, and connector 3, which helps improve the production efficiency of the reset module 100.

[0045] It is understood that the aforementioned connector 3 can be a metal connecting piece, a metal connecting plate, or a metal connecting block, and this embodiment does not specifically limit it.

[0046] Optionally, please refer to Figure 4 and Figure 5 , Figure 5 This is a schematic diagram of the base structure disclosed in the embodiments of this application. The base 1 includes a first plate portion 12 and a second plate portion 13. The first plate portion 12 has a first shaft hole 121, and the opening of the first mounting space 11 is opposite to the first plate portion 12 along the axial direction O of the rotating shaft 2. The second plate portion 13 surrounds and connects to the edge of the first plate portion 12, and the second plate portion 13 and the first plate portion 12 together form the first mounting space 11. An abutment portion 131 is integrally disposed on the second plate portion 13. Along the radial direction of the rotating shaft 2, the abutment portion 131 extends from the second plate portion 13 toward one end close to the rotating shaft 2, and the elastic reset member 4 is configured to abut against the abutment portion 131.

[0047] The base 1 includes a first plate portion 12 and a second plate portion 13. The first plate portion 12 is surrounded and connected to the edge of the base 13, and the opening of the first mounting space 11 is opposite to the first plate portion 12 along the axial direction O of the rotating shaft 2. This allows the connecting member 3 and the elastic reset member 4 to be inserted into the first mounting space 1 through the opening of the first mounting space 11, thus reducing the installation difficulty of the reset module 100. Furthermore, when maintenance or replacement of the reset module 100 components is required, disassembly and operation can be easily performed through the opening, thereby reducing the maintenance cost and difficulty of the reset module 100.

[0048] Furthermore, the abutment portion 131 is integrally formed on the second plate portion 13, and extends from the second plate portion 13 toward one end closer to the rotating shaft 2 along the radial direction of the rotating shaft 2. This allows the abutment portion 131 to also be located in the first mounting space 11, thereby enabling the elastic reset member 4 to better engage with the abutment portion 131 and preventing the elastic reset member 4 from detaching from the abutment portion 131. In addition, the integral formation of the abutment portion 131 on the second plate portion 13 also enhances the overall strength of the base 1, which helps to improve the stability of the reset module 100 in use.

[0049] It is understood that the first plate portion 12 can be a circular plate portion, a square plate portion, or a rectangular plate portion, etc. In this embodiment, the first plate portion 12 is a rectangular plate portion as an example. The length direction of the first plate portion 12 is the first direction X, and the width direction of the first plate portion 12 is the second direction Y, which will be explained later.

[0050] It is understood that the first plate portion 12 and the second plate portion 13 mentioned above can be an integral structure manufactured by integral molding, or they can be manufactured separately and then connected together. This embodiment does not specifically limit this.

[0051] In some embodiments, the reset module 100 further includes a limiting component 5, which is sleeved on the second end 22 and located in the first mounting space 11 along the axial direction O of the rotating shaft 2. The limiting component 5 is configured to clamp the base 1 to limit the position of the base 1 on the rotating shaft 2.

[0052] The limiting component 5 is located in the first installation space 11 and sleeved on the second end 22 of the rotating shaft 2. This allows the base 1 to be clamped along the axial direction O of the rotating shaft 2, thereby accurately limiting the axial position of the base 1 on the rotating shaft 2 and preventing the base 1 from shifting in the axial direction O during use. This ensures the relative position stability of the base 1, rotating shaft 2, connecting piece 3 and elastic reset piece 4, allowing the entire reset module 100 to operate smoothly.

[0053] Furthermore, since the limiting component 5 restricts the position of the base 1, and the elastic reset member 4 is located between the base 1 and the connecting member 3, its axial compression or initial installation state is stably maintained. This avoids changes in the preload of the elastic reset member 4 due to axial movement of the base 1, thereby ensuring that the torsional deformation of the elastic reset member 4 under the action of the actuating member 31 is stable, thus ensuring the accuracy of the magnitude and direction of the reset force it provides, which helps to ensure consistent reset action of the handle 201.

[0054] Optionally, the limiting component 5 includes a first limiting member 51 and a second limiting member 52. Along the axial direction O of the rotating shaft 2, the first limiting member 51 is disposed between the connecting member 3 and the base 1, and abuts against both the connecting member 3 and the base 1. An elastic reset member 4 is sleeved on the first limiting member 51. A surrounding recess 251 is provided on the circumferential surface of the rotating shaft 2. The recess 251 is located on the side of the connecting member 3 near the second end 22. The second limiting member 52 is disposed in the recess 251 and abuts against the connecting member 3. The first limiting member 51 and the second limiting member 52 are configured to jointly limit the position of the base 1 along the axial direction O of the rotating shaft 2.

[0055] The first limiting member 51 is located between the connecting member 3 and the base 1 and abuts against both. The second limiting member 52 is located in the recess 251 of the rotating shaft 2 and abuts against the connecting member 3. This allows the first limiting member 51 and the second limiting member 52 to together form a bidirectional clamping positioning structure. This can restrict the displacement of the base 1 from both axial directions of the rotating shaft 2, resulting in higher positioning accuracy. It can also prevent axial movement of the base 1 caused by vibration, force, or other factors, ensuring the stability of the relative positions of each component.

[0056] In addition, by having the first limiting member 51 located between the connecting member 3 and the base 1 and abutting against both, and the elastic reset member 4 sleeved on the first limiting member 51, the space occupied in the axial direction O along the rotating shaft 2 can be reduced, and the first limiting member 51 can also be prevented from interfering with the torsional deformation of the elastic reset member 4.

[0057] It is understood that the first limiting member 51 mentioned above can be a circular sleeve or a circular gasket, etc., and this embodiment does not specifically limit it.

[0058] It is understood that the aforementioned second limiting member 52 may be a snap ring or an elastic snap ring, etc., and this embodiment does not specifically limit it.

[0059] 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, the outer end abuts against the abutting part 131 of the base 1, and the actuating element 31 abuts against the outer end of the planar spiral spring. Thus, the rotation of the rotating shaft 2 can 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.

[0060] 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.

[0061] The following explanation will take the elastic reset element 4 as an example of a torsion spring.

[0062] Optionally, please refer to Figures 6 to 8 , Figure 6 The schematic diagram of the reset module disclosed in this application is shown from another perspective. Figure 7 yes Figure 6 Cross-sectional view at the FF point. Figure 8 This is a schematic diagram of the structure of the elastic reset member disclosed in the embodiments of this application. The 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 abuts against the abutment portion 131. A toggle member 31 is disposed below the second torsion arm 43 and abuts against the second torsion arm 43. The toggle 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, so that the elastic reset member 4 undergoes torsional deformation.

[0063] With the main body 41 of the torsion spring sleeved on the rotating shaft 2, and the first torsion arm 42 and the second torsion arm 43 extending radially along the rotating shaft 2, the elastic reset member 4 can be completely accommodated within 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, allowing the entire reset module 100 to be assembled and manufactured independently and subjected to reset testing.

[0064] It is understood that the first torsion arm 42 can be fixedly connected to the base 1. In this way, when the second torsion arm 43 rotates along the first rotation direction A, the position of the first torsion arm 42 is fixed, thereby realizing the torsional deformation of the elastic reset member 4 to provide rotational reset force to the handle 201.

[0065] It can be understood that the abutment part 131 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 abut on the abutment part 131 without additional calibration, thereby improving the assembly efficiency of the reset module 100.

[0066] The rotation of 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 achieve both bidirectional rotation and bidirectional reset of handle 201. Two abutment portions 131 are arranged opposite each other along the radial direction of the rotating shaft 2. A first torsion arm 42 and a second torsion arm 43 abut against the two abutment portions 131 respectively. Two actuating members 31 are included: a first actuating member 311 and a second actuating member 312, which are arranged opposite each other along the radial direction of the rotating shaft 2. Both 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 disposed below the first torsion arm 42 and abuts against the first torsion arm 42. The second actuating member 312 is disposed below the second torsion arm 43 (as shown in the figure, below in the vertical direction) and abuts against the second torsion arm 43. When the rotating shaft 2 is configured to rotate along the first rotation direction A, the second actuating member 312 drives the second torsion arm 43 to rotate and causes the main body 41 to undergo torsional deformation, 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. The rotating shaft 2 is also configured to rotate along the second rotation direction B, so that the first actuating member 311 drives the first torsion arm 42 to rotate and causes the main body 41 to undergo torsional deformation, 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.

[0067] Two abutment portions 131 are arranged radially opposite each other along the rotating shaft 2. A first torsion arm 42 and a second torsion arm 43 abut against the two abutment portions 131 respectively. 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 cause the main body 41 to undergo torsional deformation, 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 torsion arm 43 can be driven to rotate by the second actuating member 312, causing torsional deformation of 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, causing torsional deformation of 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, causing the main body 41 to undergo torsional deformation. This provides 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. Therefore, 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 for the actuating element 31 and the rotating shaft 2 through the elastic reset element 4. 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.

[0068] 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 abutting part 131 and the second abutting part 131 are also spaced apart along the first direction X.

[0069] 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 is within the range of 0° to 90°, for example, it can be 10°, 26°, 45°, 72° or 90°, which can be set according to the actual use.

[0070] 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 9 and Figure 10 , Figure 9 This is a schematic diagram of the reset module for the handle in the first unlocking direction. Figure 10 This is a schematic diagram of the reset module for the handle in the second unlocking direction. The first actuating element 311 is fixedly connected 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 member 312 separates from the connecting member 3, so that the handle 201 drives the rotating shaft 2 and the first actuating member 311 to rotate, so that the first actuating member 311 abuts against the second torsion arm 43, and the second actuating member 312 is configured to abut against the first torsion arm 42 when installed on the connecting member 3. 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 allows the reset module 100 to directly adapt to all door types without distinguishing between left-opening and right-opening doors during production, thus improving the adaptability of the reset module 100.

[0071] 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.

[0072] It is understandable that the aforementioned first actuating element 311 can be a bolt or pin welded to the connecting element 3, which allows for separate production and assembly, thus reducing the manufacturing difficulty of the overall structure. Alternatively, the aforementioned first actuating element 311 can also be formed by bending the connecting element 3. For example, the first actuating element 311 can be formed by bending at least partially towards the first end 21 along the radial direction of the connecting element 3. This improves the rigidity of the actuating element 31 and the connecting element 3 as a whole, resulting in higher structural reliability and a shorter production cycle.

[0073] 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.

[0074] 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 201. 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.

[0075] 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 9 (in the vertical direction of the paper), and the first actuating member 311 and the second actuating member 312 abut against the abutting part 131. 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 bottom. 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.

[0076] Optionally, please refer to Figures 11 to 13 , Figure 11 This is a top view of the reset module disclosed in the embodiments of this application. Figure 12 yes Figure 11 Sectional view at point GG. Figure 13 yes Figure 12 A partial enlarged view of point H in the middle. The reset module 100 also includes a gasket 6, which is sleeved on the rotating shaft 2 and along the axial direction O of the rotating shaft 2. The gasket 6 abuts against the second limiting member 52 and the connecting member 3 respectively.

[0077] There is friction between the second limiting member 52 and the connecting member 3. Long-term friction will cause wear on the contact surface. By setting a gasket 6 between the second limiting member 52 and the connecting member 3 to isolate these contact surfaces, the service life of the base 1, the elastic reset member 4 and the limiting member can be improved, and the reset accuracy of the entire reset module 100 can be avoided due to wear.

[0078] 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.

[0079] 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.

[0080] Optionally, please refer to Figure 13 and Figure 14 , Figure 14 This is a schematic diagram of the structure of the rotating shaft disclosed in the embodiments of this application. The rotating shaft 2 includes a first shaft segment 23 and a second shaft segment 24 connected in sequence from the first end 21 to the second end 22. The outer diameter of the second shaft segment 24 is larger than the outer diameter of the first shaft segment 23. The base 1, the elastic reset member 4, the connecting member 3, and the limiting component 5 are all sleeved on the second shaft segment 24, and the base 1 abuts against the side of the first shaft segment 23 near the second end 22.

[0081] By making the outer diameter of the second shaft segment 24 larger than that of the first shaft segment 23, an axial stepped surface can be formed on the side of the first shaft segment 23 near the second end 22. The base 1 is sleeved on the second shaft segment 24 and abuts against the stepped surface near the first end 21, thereby restricting its movement towards the first end 21. This avoids the base 1 moving upward along the axial direction O, which would affect the normal use of the elastic reset member 4, thereby improving the stability of the reset function of the reset module 100.

[0082] Please see Figure 15 , Figure 15 This is a schematic diagram of the structure of the notch and the locking pin abutting as disclosed in the embodiments of this application. In some embodiments, the second end 22 of the rotating shaft 2 is provided with two notches 261 along the radial direction of the rotating shaft 2. The two notches 261 are arranged opposite to each other along the radial direction of the rotating shaft 2. The connecting member 3 is provided with a second shaft hole 32. Two locking pins 321 protrude from the inner wall of the second shaft hole 32. When the rotating shaft 2 passes through the second shaft hole 32, the two locking pins 321 are configured to abut against the two notches 261 respectively.

[0083] Two notches 261 on the rotating shaft 2 are arranged radially opposite each other, and two locking posts 321 are correspondingly arranged on the inner wall of the second shaft hole 32 of the connector 3. In this way, the locking posts 321 can only be abutted and fixed when they are completely aligned with the notches 261. This foolproof design makes the reset module 100 more intuitive to assemble, thereby improving the assembly efficiency and accuracy of the reset module 100.

[0084] 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, the locking pin 321 can be used to abut against the notch 261, 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.

[0085] Optionally, the two notches 261 are arranged opposite each other along the second direction Y. This way, on the one hand, the torsion arm and the abutment part 131 are arranged opposite each other along the first direction X, and the two notches 261 and the two locking pins 321 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 321 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.

[0086] It is understood that the two locking posts 321 mentioned above can be square locking posts 321, rectangular locking posts 321 or cylindrical locking posts 321, etc., and the shape of the corresponding notch 261 can also be square notch 261, rectangular notch 261 or cylindrical notch 261, etc. This embodiment does not make specific limitations on this.

[0087] Please see Figure 16 and Figure 17 , Figure 16 This is a schematic diagram of the structure of the smart door lock disclosed in the embodiments of this application. Figure 17 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 202, a rear shell 203, and a reset module 100 as described in the first aspect above. The front shell 202 is connected to the rear shell 203, and the front shell 202 and the rear shell 203 together define a second mounting space 204. The reset module 100 is disposed in the second mounting space 204. The handle 201 is located on the side of the front shell 202 opposite to the second mounting space 204. The first end 21 of the rotating shaft 2 passes through the front shell 202 to connect with the handle 201. The reset module 100 is connected to the rear shell 203 so that the rear shell 203 covers the opening of the base 1.

[0088] The reset module 100 allows for independent pre-installation and reset function testing before shipment. When the reset module 100 is installed in the second installation space 204 of the smart door lock 200, there is no need to adjust the position of the internal components of the reset module 100. It is only necessary to fix the reset module 100 to the rear shell 203. This improves the assembly efficiency and accuracy of the entire smart door lock 200.

[0089] Secondly, the front shell 202 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 203, the layout of the entire installation space can be optimized, avoiding mutual interference between modules in the installation space, or stacking causing the entire smart door lock 200 to be too thick.

[0090] In addition, by setting the reset module 100 in the second installation space 204 formed by the front shell 202 and the rear shell 203, and the rear shell 203 being able to cover the opening of the base 1, the reset module 100 can form a closed space as a whole, thereby preventing external impurities (such as dust, moisture, metal shavings, etc.) from entering the first installation space 11 and affecting the elastic reset member 4, the rotating shaft 2, the connecting member 3, and other components, causing the handle 201 to be unable to rotate or reset, thereby improving the overall stability of the smart door lock 200.

[0091] Optionally, the base 1 includes a plurality of fixing parts 14 located at the edge of the base 1 along the radial direction of the rotating shaft 2 and along the axial direction O of the rotating shaft 2. The fixing parts 14 are disposed on the side of the base 1 near the second end 22. The fixing parts 14 are provided with a first mounting hole 141, and the rear shell 203 is provided with a plurality of second mounting holes 203a. The first mounting holes 141 and the second mounting holes 203a are provided in a one-to-one correspondence. The first mounting holes 141 and the second mounting holes 203a are configured to allow fasteners 205 to pass through, so that the base 1 is connected to the rear shell 203.

[0092] The base 1 includes multiple fixing parts 14, which are located at the edge of the base 1 along the radial direction of the rotating shaft 2. Each fixing part 14 has a first mounting hole 141, and the rear shell 203 has a corresponding second mounting hole 203a. Fasteners 205 pass through the first mounting holes 141 and the second mounting holes 203a, thereby connecting the base 1 to the rear shell 203. This structure, formed by multiple fixing parts 14, provides multi-point support, which evenly distributes the force borne by the reset module 100 during operation to multiple points on the rear shell 203, avoiding local stress concentration that could lead to loosening of the connection or deformation of the rear shell 203.

[0093] Furthermore, by positioning the fixing part 14 on the side of the base 1 near the second end 22 along the axial direction O of the rotating shaft 2, that is, opposite to the first plate part 12, and positioning the fixing part 14 on the edge of the base 1 along the radial direction of the rotating shaft 2, that is, connected to the second plate part 13, the fixing part 14 can be positioned to avoid the elastic reset member 4, the connecting member 3 and other components in the first mounting space 11, thereby avoiding affecting the rotation and reset process of the handle 201.

[0094] It is understood that the fastener 205 can be a self-tapping screw or a machine screw, and the corresponding first mounting hole 141 and second mounting hole 203a can be a threadless through hole or a threaded hole, etc. This embodiment does not make specific limitations on this.

[0095] It is understood that the aforementioned fixing part 14 may include four parts, which are respectively connected to the four corners of the base 1 to ensure the force balance of the base 1. Of course, the fixing part 14 may also be provided at the center of the four sides of the base 1. This embodiment does not specifically limit this.

[0096] It is understood that the aforementioned fixing part 14 can be a plate or block connected to the edge of the second plate part 13. Along the axial direction O of the rotating shaft 2, the fixing part 14 is disposed opposite to the first plate part 12 and is respectively connected to both sides of the second plate part 13. In the radial direction of the rotating shaft 2, the fixing part 14 extends from the second plate part 13 toward the side closer to the rotating shaft 2.

[0097] It is understood that the aforementioned fixing part 14 and the second plate part 13 can be an integral structure manufactured by integral molding, or they can be manufactured separately and then connected together. This embodiment does not specifically limit this.

[0098] 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.
