Description

Technical Field

[0001] This application relates to the field of smart door lock technology, specifically to handle devices and smart locks. Background Technology

[0002] As an upgrade from traditional mechanical locks, smart locks offer significant advantages in user identification, security, and ease of management thanks to their electronic control methods such as biometrics and password verification. Their core structure typically includes indoor and outdoor panel components. The outdoor panel integrates an interactive unit such as a fingerprint recognition module and password input interface, while the indoor panel houses the power supply system and main control circuit board. Power transmission and signal exchange are achieved between the two via wires. These products are widely used in residential and commercial settings, becoming an important component of modern security systems.

[0003] Some existing products use a fixed handle design, with the opening and closing direction determined at the factory. Users need to select a specific model based on the door's characteristics. Other adjustable handles can achieve directional adaptation through internal structural reconfiguration, but the adjustment process requires disassembling the panel shell, resetting the transmission components, and even rewiring. This involves multiple sets of screws for fixing and mechanical linkage calibration, making the operation complex and posing a risk of damaging electronic components.

[0004] However, the fixed-direction handles result in poor product versatility, which increases inventory management costs. At the same time, the low user installation error tolerance means that if the wrong model is selected, the entire product needs to be replaced, which increases the cost. Utility Model Content

[0005] This application provides a handle device and a smart lock to solve the problem of poor versatility caused by the inability to adjust the handle direction of the smart lock.

[0006] In a first aspect, this application provides a handle device, including a panel and a handle body. The panel has a mounting surface adapted to be connected to a door body. A first handle mounting portion and a second handle mounting portion are respectively provided on both sides of the mounting surface, and the first and second handle mounting portions are rotationally symmetrical with respect to the rotation center of the mounting surface. The handle body is adapted to be mounted on the first or second handle mounting portion. The handle body has a connecting portion, and a positioning pin is provided on the side of the connecting portion facing the mounting surface. Both the first and second handle mounting portions have positioning holes, and the positioning holes on the first and second handle mounting portions are rotationally symmetrical with respect to the rotation center of the mounting surface. The positioning holes are inserted into the positioning pins.

[0007] Beneficial effects: The rotationally symmetrical double-mounting structure relative to the rotation center of the mounting surface allows for 180° directional adjustment of the handle body. It can be reversed according to the actual door installation direction and prevents hand pinching, significantly improving product versatility. Installation only requires selecting the corresponding mounting position; there is no need to disassemble the panel or adjust the internal structure, reducing inventory management costs and the risk of user selection errors, aligning with modular design principles. The positioning pin is a rotationally symmetrical plug-in positioning structure relative to the rotation center of the mounting surface, ensuring automatic and accurate alignment during handle reversal installation, eliminating the need for manual calibration. The unidirectional guiding characteristic of the positioning pin and positioning hole simplifies the operation process, improves reversal efficiency, and enhances structural stability.

[0008] In one alternative embodiment, a plurality of locating pins are provided, and the plurality of locating pins are spaced apart on the side of the connecting portion facing the mounting surface.

[0009] Beneficial effects: The distributed layout of multiple locating pins creates redundant constraints, effectively suppressing deflection displacement of the handle under stress and improving torsional resistance. The spaced arrangement design increases the contact area, disperses stress concentration, and extends service life.

[0010] In one optional embodiment, the connecting portion has a first connecting hole, and both the first handle mounting portion and the second handle mounting portion are provided with second connecting holes. The second connecting holes located on the first handle mounting portion and the second handle mounting portion are rotationally symmetrical with respect to the rotation center of the mounting surface. The first connecting hole and the second connecting hole are correspondingly provided, and the connecting portion is adapted to be connected to the panel by a connector that passes through the first connecting hole and the second connecting hole.

[0011] Beneficial effects: The first connecting hole, which is rotationally symmetrical with respect to the rotation center of the mounting surface, and the second connecting hole, which are also rotationally symmetrical with respect to the rotation center of the mounting surface, both mate with universal connectors, enabling rapid alignment of mechanical fixing points. The use of standardized connection schemes (such as screws of uniform specifications) reduces the complexity of parts, improves assembly efficiency, and eliminates the need for special tools.

[0012] In one optional embodiment, multiple first connecting holes and multiple second connecting holes are provided, and the multiple first connecting holes are respectively provided in a one-to-one correspondence with the multiple second connecting holes on the first handle mounting part and the second handle mounting part.

[0013] Beneficial effects: Multiple sets of first and second connecting holes form a matrix-like fixing system, providing multi-dimensional constraint. The symmetrically distributed holes maintain balanced force during reversal, avoiding the risk of single-point failure, while also adapting to the installation strength requirements of door bodies made of different materials.

[0014] In one optional embodiment, the handle body is further provided with a handle portion and a transition portion, wherein the handle portion and the connecting portion are respectively located at both ends of the transition portion.

[0015] Beneficial effects: The three-section spatial layout modularizes functional areas, the extended handle design expands the operating space, and the transition section acts as a stress buffer zone to reduce the risk of root breakage. The split structure facilitates injection molding and improves yield. Simultaneously, the transition section fits snugly against the side of the panel, creating a gap between the handle and the door body, allowing the user's fingers to easily enter and operate the door.

[0016] In one alternative embodiment, the projection of the handle portion onto the door body along the direction close to the door body is spaced apart from the projection of the panel onto the door body along the direction close to the door body.

[0017] Beneficial effect: The projection of the handle on the door body along the direction close to the door body, and the interval between the projection of the panel on the door body along the direction close to the door body, can make the handle and the panel staggered, making it easier for users to hold the handle to open the door.

[0018] In one alternative embodiment, the handle portion has an arc-shaped segment in the middle, the arc-shaped segment protruding in a direction away from the door body.

[0019] Beneficial effects: The curved protrusion conforms to the natural grip curve of the palm, improving operating comfort. The streamlined design optimizes the lever arm length and reduces the opening torque, making it especially suitable for elderly users.

[0020] In an optional embodiment, a flexible pad is further included. The flexible pad is disposed between the connecting portion and the door body. The side of the flexible pad facing the mounting portion has a snap-fit ​​protrusion, and the end of the snap-fit ​​protrusion away from the flexible pad has a snap-fit ​​portion. The connecting portion has a first snap-fit ​​hole, and both the first handle mounting portion and the second handle mounting portion have second snap-fit ​​holes. The second snap-fit ​​holes on the first handle mounting portion and the second handle mounting portion are rotationally symmetrical with respect to the rotation center of the mounting surface. The first snap-fit ​​hole and the second snap-fit ​​hole are arranged opposite to each other. The snap-fit ​​portion passes through the first snap-fit ​​hole and the second snap-fit ​​hole sequentially, and the cross-sectional area of ​​the snap-fit ​​portion in the direction perpendicular to the flexible pad is larger than the cross-sectional areas of the first snap-fit ​​hole and the second snap-fit ​​hole in the direction perpendicular to the flexible pad.

[0021] Beneficial effects: The flexible pad provides vibration damping and tolerance compensation, while the integrated elastic structure with snap-fit ​​protrusions simplifies installation. The interference fit design eliminates play and prevents noise, while also providing waterproof and dustproof sealing properties.

[0022] Secondly, this application also provides a smart lock, including a handle device.

[0023] Since smart locks include a handle mechanism and have the same effect as a handle mechanism, they will not be described in detail here. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, 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.

[0034] The following is combined with Figures 1 to 6 This describes an embodiment of the present application.

[0035] According to an embodiment of this application, a handle device is provided, including a panel 1 and a handle body 2. The panel 1 is provided with a mounting surface adapted to be connected to a door body. A first handle mounting portion 101 and a second handle mounting portion 102 are respectively provided on both sides of the mounting surface, and the first handle mounting portion 101 and the second handle mounting portion 102 are rotationally symmetrical with respect to the rotation center of the mounting surface. The handle body 2 is adapted to be mounted on the first handle mounting portion 101 or the second handle mounting portion 102.

[0036] Understandably, the first handle mounting part 101 and the second handle mounting part 102 are configured to be rotationally symmetrical with respect to the rotation center of the mounting surface, and the handle body 2 is also configured to be rotationally symmetrical with respect to the rotation center of the mounting surface, so that the handle body 2 can be freely assembled onto one of the first handle mounting part 101 and the second handle mounting part 102, thereby improving applicability.

[0037] It should be noted that the connecting structure provided on the handle body 2 is rotationally symmetrical with respect to the rotation center of the mounting surface. Furthermore, the connecting structures on the first handle mounting part 101 and the second handle mounting part 102 are also rotationally symmetrical with respect to the rotation center of the mounting surface.

[0038] In this embodiment, the dual mounting structure, which is rotationally symmetrical with respect to the rotation center of the mounting surface, allows for 180° directional adjustment of the handle body. This enables reversible installation based on the actual door installation direction and prevents hand pinching, significantly improving product versatility. Installation only requires selecting the corresponding mounting position; there is no need to disassemble panel 1 or adjust the internal structure, reducing inventory management costs and the risk of user selection errors, aligning with the modular design concept.

[0039] In one embodiment, the handle body 2 is provided with a connecting part 201, and the connecting part 201 has a positioning pin 204 on the side facing the mounting surface. The first handle mounting part 101 and the second handle mounting part 102 are both provided with positioning holes 103. The positioning holes 103 on the first handle mounting part 101 and the second handle mounting part 102 are rotationally symmetrical with respect to the rotation center of the mounting surface. The positioning holes 103 are inserted into the positioning pin 204.

[0040] Optionally, the connecting part 201 is configured as a plate-like structure and is located between the mounting surface and the door body. Both the first handle mounting part 101 and the second handle mounting part 102 are configured as groove structures. After the connecting part 201 is connected to either the first handle mounting part 101 or the second handle mounting part 102, the connecting part 201 can fill the groove structure, thereby ensuring the fit between the panel 1 and the door body.

[0041] Optionally, the cross-sectional shape of the positioning pin 204 can be set to one of a circle, a near-circular shape, or a polygon, and the positioning hole 103 is adapted to the cross-sectional shape of the positioning pin 204.

[0042] Optionally, the end of the positioning pin 204 facing the positioning hole 103 is set as a pointed end, which makes the process of inserting the positioning pin 204 into the positioning hole 103 more convenient.

[0043] In this embodiment, the positioning pin is configured as a rotationally symmetrical plug-in positioning structure relative to the rotation center of the mounting surface, ensuring accurate automatic alignment during handle reversal installation and avoiding manual calibration steps. The unidirectional guiding characteristics of the positioning pin 204 and the positioning hole 103 simplify the operation process, improve reversal efficiency, and enhance structural stability.

[0044] In one embodiment, a plurality of locating pins 204 are provided, and the plurality of locating pins 204 are spaced apart on the side of the connecting portion 201 facing the mounting surface.

[0045] Optionally, multiple locating pins 204 may be spaced apart along the extension direction of the connecting portion 201.

[0046] In this embodiment, the distributed layout of multiple locating pins 204 creates redundant constraints, effectively suppressing deflection displacement of the handle under stress and improving torsional resistance. The spaced arrangement design increases the contact area, disperses stress concentration, and extends service life.

[0047] In one embodiment, the connecting portion 201 has a first connecting hole 205, and both the first handle mounting portion 101 and the second handle mounting portion 102 are provided with second connecting holes 104. The second connecting holes 104 located on the first handle mounting portion 101 and the second handle mounting portion 102 are rotationally symmetrical with respect to the rotation center of the mounting surface. The first connecting hole 205 and the second connecting hole 104 are correspondingly provided, and the connecting portion 201 is adapted to be connected to the panel 1 by a connector that passes through the first connecting hole 205 and the second connecting hole 104.

[0048] Alternatively, the connector can be a screw or bolt.

[0049] Optionally, the inner wall of the second connecting hole 104 may be provided with a threaded structure, so that the connector can be connected to the second connecting hole 104 by threads, and the connecting part 201 is fixed on the mounting surface.

[0050] In this embodiment, both the first connecting hole 205, which is rotationally symmetrical with respect to the rotation center of the mounting surface, and the second connecting hole 104, which is rotationally symmetrical with respect to the rotation center of the mounting surface, cooperate with universal connectors to achieve rapid alignment of mechanical fixing points. The use of standardized connection schemes (such as screws of uniform specifications) reduces the complexity of accessories, improves assembly efficiency, and eliminates the need for special tools.

[0051] In one embodiment, multiple first connecting holes 205 and multiple second connecting holes 104 are provided, and the multiple first connecting holes 205 are respectively provided in a one-to-one correspondence with the multiple second connecting holes 104 on the first handle mounting part 101 and the second handle mounting part 102.

[0052] In this embodiment, multiple sets of first connecting holes 205 and second connecting holes 104 form a matrix-type fixing system, providing multi-dimensional constraint force. The symmetrically distributed holes maintain balanced force during reversal, avoiding the risk of single-point failure, while adapting to the installation strength requirements of door bodies made of different materials.

[0053] In one embodiment, the handle body 2 is further provided with a handle portion 203 and a transition portion 202. The handle portion 203 and the connecting portion 201 are respectively provided at both ends of the transition portion 202 in the direction away from the door body, and the handle portion 203 and the connecting portion 201 are respectively located on two opposite sides of the transition portion 202.

[0054] Optionally, both the transition portion 202 and the handle portion 203 are configured as plate-like structures. The transition portion 202 fits against the side of the panel 1, which allows the handle portion 203 to fit the panel 1 more closely, reducing the gap between the handle body 2 and the panel 1, thereby reducing the space occupied by the handle device.

[0055] In this embodiment, the three-section spatial layout modularizes the functional areas. The extended design of the handle 203 expands the operating space, and the transition section 202 acts as a stress buffer to reduce the risk of root breakage. The split structure facilitates injection molding and improves the yield rate. At the same time, the transition section 202 fits against the side of the panel 1, creating a gap between the handle 203 and the door body, which facilitates the user's fingers entering the gap and making it easier for the user to operate the door.

[0056] In one embodiment, the projection of the handle portion 203 onto the door body along the direction close to the door body is spaced apart from the projection of the panel 1 onto the door body along the direction close to the door body.

[0057] In this embodiment, the projection of the handle portion 203 onto the door body along the direction close to the door body is spaced apart from the projection of the panel 1 onto the door body along the direction close to the door body, so that the handle portion 203 and the panel 1 are staggered, making it convenient for the user to hold the handle portion 203 to open the door.

[0058] In one embodiment, the handle portion 203 has an arc-shaped segment 206 in the middle, and the arc-shaped segment 206 protrudes in a direction away from the door body.

[0059] In this embodiment, the arc-shaped protrusion conforms to the natural grip curve of the palm, improving operating comfort. The streamlined design optimizes the lever arm length and reduces the opening torque, making it particularly suitable for elderly users.

[0060] In one embodiment, a flexible pad 3 is also included. The flexible pad 3 is disposed between the connecting portion 201 and the door body. The side of the flexible pad 3 facing the mounting portion has a snap-fit ​​protrusion 301, and the end of the snap-fit ​​protrusion 301 away from the flexible pad 3 is provided with a snap-fit ​​portion 302. The connecting portion 201 has a first snap-fit ​​hole 207, and both the first handle mounting portion 101 and the second handle mounting portion 102 are provided with second snap-fit ​​holes 105. The second snap-fit ​​holes 105 on the first handle mounting portion 101 and the second handle mounting portion 102 are rotationally symmetrical with respect to the rotation center of the mounting surface. The first snap-fit ​​hole 207 and the second snap-fit ​​hole 105 are arranged opposite to each other. The snap-fit ​​portion 302 passes through the first snap-fit ​​hole 207 and the second snap-fit ​​hole 105 in sequence, and the cross-sectional area of ​​the snap-fit ​​portion 302 in the direction perpendicular to the direction away from the flexible pad 3 is larger than the cross-sectional area of ​​the first snap-fit ​​hole 207 and the second snap-fit ​​hole 105 in the direction perpendicular to the flexible pad 3.

[0061] Optionally, the first snap-fit ​​hole 207 and the second snap-fit ​​hole 105 can be configured as an elongated structure. This configuration allows the snap-fit ​​part 302 to deform when passing through the first snap-fit ​​hole 207 and the second snap-fit ​​hole 105, and to return to its original shape after passing through completely, thus achieving snap-fit ​​and improving the ease of installation.

[0062] In this embodiment, the flexible pad 3 provides vibration damping and tolerance compensation, while the integrated elastic structure of the snap-fit ​​protrusion 301 simplifies the installation process. The interference fit design eliminates play and prevents noise, while also providing waterproof and dustproof sealing properties.

[0063] According to an embodiment of this application, another aspect provides a smart lock, including a handle device.

[0064] Since smart locks include a handle mechanism and have the same effect as a handle mechanism, they will not be described in detail here.
