When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0044] The present invention provides a charging device for intelligent wearable products.

[0045] Combined Figures 1 to 3 As shown, in an embodiment of the present invention, the charging device for intelligent wearable products includes a housing 11, a rotating member 20, at least two abutting members 30, and a charging module; the rotating member 20 is rotatably mounted on the housing 11; at least two abutting members 30 are movably mounted on the housing 11 and are arranged at intervals along the circumferential direction of the rotation of the rotating member 20. At least two abutting members 30 enclose a charging position for placing the intelligent wearable product. The rotating member 20 is drivingly connected to at least two abutting members 30; the charging module is provided on at least one abutting member 30; wherein, the rotating member 20 is driven to rotate to drive at least two abutting members 30 to move radially along the rotating member 20 to change the size of the charging position.

[0046] Among them, the smart wearable product can be a smart ring 60, a smart bracelet, etc. The housing 11 refers to the basic structure that bears the smart wearable product and other components in the charging device of the smart wearable product. The rotating member 20 and the abutting member 30 can be arranged inside the housing 11 or outside the housing 11. For example, when the rotating member 20 is arranged inside the housing 11, the housing 11 can specifically adopt an injection-molded cavity structure, and structures such as a limiting boss, a clamping groove or a bracket are arranged inside to fix the rotating member 20. The rotating member 20 is a driving component that converts rotational motion into linear displacement, such as a turntable or a gear structure with an arc-shaped groove. The abutting member 30 directly contacts and clamps the product, and specifically can adopt a combination of a slider 31 and a guide rail to ensure the accuracy of the moving track when moving radially. The charging module is used to realize the function of electric energy transmission, such as embedding a wireless charging coil or an elastic conductive contact on the surface of the abutting member 30.

[0047] Specifically, when the rotating member 20 rotates, it will drive the abutting member 30 to move along the radial direction of the rotating member 20. More than two abutting members 30 approach or move away from the central position of the rotating member 20 synchronously, so as to change the size of the charging position formed by enclosing each abutting member 30 to meet the clamping requirements of products of different sizes. After the charging module moves to the surface of the product along with the abutting member 30, electric energy transmission is realized through contact charging or electromagnetic induction. This design realizes multi-point synchronous adjustment through a single driving source, which not only ensures the uniform distribution of the clamping force, but also avoids the structural complexity brought by multiple driving sources.

[0048] Compared with the prior art, the traditional charging box adopts a fixed clamping structure and needs to be produced separately for different sizes. Through the linkage design of the rotating member 20 and the abutting member 30 in this solution, the charging device has the ability of adaptive adjustment, and the same device can be adapted to products of different specifications. Compared with the single-point adjustment scheme using springs or slide rails, the circumferential multi-point synchronous adjustment of this design avoids the offset problem of the product during the charging process. Compared with the scheme using multiple transmission structures such as lead screws and worm gears to realize size adjustment, this design can realize multi-point synchronous adjustment through a single rotating member 20, reduce the structural complexity, and ensure the uniform distribution of the clamping force.

[0049] Through the above technical solution, this application solves the problem of adaptation limitation caused by the fixed size of the charging device, and realizes the compatibility of a single device with products of different sizes. Users do not need to purchase multiple charging boxes to charge smart wearable products of different specifications, which reduces the use cost and improves the operation convenience. The design that the charging module moves synchronously with the abutting member 30 ensures that the charging interface is always in close contact with the product surface, improving the energy transmission efficiency.

[0050] Combined with Figure 4 and Figure 7As shown, in an embodiment of the present invention, a rotation groove 21 is formed on the surface of one of the rotating member 20 and the abutting member 30, and a transmission pin 33 is provided on the other. The rotation groove 21 is arc-shaped, and the transmission pin 33 is embedded in the rotation groove 21;

[0051] When the rotating member 20 is driven to rotate, the groove wall of the rotation groove 21 abuts against the transmission pin 33 to drive the abutting member 30 to move radially along the rotating member 20.

[0052] Among them, the rotation groove 21 refers to an arc-shaped groove hole structure formed on both sides of the surface of the rotating member 20 or the abutting member 30 and penetrating through. Specifically, it can be formed by machining or injection molding processes on the surface of the rotating member 20 or the abutting member 30. The radian of the rotation groove 21 matches the movement path of the transmission pin 33 and is used to define the movement direction of the transmission pin 33. Among them, the transmission pin 33 refers to a columnar protrusion structure provided on the rotating member 20 or the abutting member 30. Specifically, a metal pin or a plastic protrusion can be used. Its diameter size is slightly smaller than the width of the rotation groove 21 to ensure sliding fit with the groove wall of the rotation groove 21. After the transmission pin 33 is embedded in the rotation groove 21, the side wall of the rotation groove 21 forms a limit constraint on the transmission pin 33, converting the rotational motion of the rotating member 20 into a linear displacement for driving the abutting member 30.

[0053] Specifically, when the rotating member 20 is driven to rotate, the arc-shaped groove wall of the rotation groove 21 comes into contact with the transmission pin 33, and the groove wall exerts a lateral thrust on the transmission pin 33. Since the radius of curvature of the rotation groove 21 changes along the circumferential direction, the transmission pin 33 generates a linear displacement along the radial direction of the rotating member 20 under the push of the groove wall of the rotation groove 21. For example, when the rotation groove 21 is designed as an involute arc, the transmission pin 33 will gradually move outward as the rotation angle of the rotating member 20 increases. By adjusting the radian parameters of the rotation groove 21, the movement stroke and speed of the abutting member 30 can be controlled, so as to adapt to the clamping requirements of smart wearable products of different sizes.

[0054] Compared with traditional charging devices that usually adopt a clamping structure of a fixed size or require manual adjustment of multiple independent components, resulting in low adaptation efficiency and complex operation. In this solution, through the embedded cooperation of the rotation groove 21 and the transmission pin 33, synchronous adjustment of each abutting member 30 under a single rotation drive is realized, avoiding the problem of independent operation of multiple adjustment mechanisms in the traditional solution. Multiple abutting members 30 can be synchronously adjusted to the target position to ensure that products of different sizes can be stably fixed and effectively contacted with the charging module. This structure simplifies the adjustment operation steps and improves the compatibility of the device with products of different specifications.

[0055] Combined Figures 3 to 9 As shown, in an embodiment of the present invention, a rotation groove 21 is formed on the surface of the rotating member 20, and a transmission pin 33 is provided on the side of the abutting member 30 facing the rotating member 20.

[0056] Among them, the rotation groove 21 refers to an arc-shaped groove formed on the surface of the rotating member 20, and the radian radius of the rotation groove 21 gradually increases along the circumferential direction of the rotation groove 21, because when the rotating member 20 rotates, it can guide the transmission pin 33 to move along the radial direction of the rotating member 20. Specifically, the rotating member 20 can be in a disc shape, a column shape or other regular or irregular shapes, and the outer periphery of the transmission pin 33 has a smooth transition to improve the smoothness when the side wall of the rotation groove 21 drives the transmission pin 33 to move, and it is not easy to deviate or jam during the motion transmission process. A plurality of rotation grooves 21 are formed on the surface of the rotating member 20, and each transmission pin 33 is matched with a rotation groove 21. For example Figure 7 As shown, when there are 4 abutting members 30, there are also 4 rotation grooves 21 and transmission pins 33 respectively. The 4 abutting members 30 are evenly spaced around the rotating member 20. The 4 rotation grooves 21 formed on the surface of the rotating member 20 are arranged in a central rotational symmetry distribution along the rotation center. When the rotating member 20 rotates, it drives the 4 abutting members 30 to move synchronously in the direction of approaching or departing from the rotating member 20. Of course, the number of abutting members 30 can also be 3, 6 or other numbers.

[0057] Compared with the solution that uses a gear-rack or a link mechanism to realize motion conversion, the structure of the gear-rack or the link mechanism requires the cooperation of multiple transmission components, and there are problems of complex assembly and easy wear. However, in this solution, the rotation motion is converted into a linear motion through the single contact interface between the rotation groove 21 and the transmission pin 33, which simplifies the mechanical structure, reduces the number of components, and at the same time reduces the error accumulation caused by multi-stage transmission, so as to ensure that the charging device arranged on the abutting member 30 can be in good contact with the smart wearable product, thereby improving the charging efficiency.

[0058] Combined with Figure 3 、 Figure 6 and Figure 9 As shown, in an embodiment of the present invention, the charging device of the smart wearable product further includes a fixing bracket 40. The fixing bracket 40 is installed on the housing 11, and the fixing bracket 40 is formed with at least two guiding channels 41 extending along the radial direction of the rotating member 20;

[0059] Each abutting member 30 includes a sliding block 31 and an abutting block 32 connected to each other. At least a part of a sliding block 31 is movably arranged in a guiding channel 41, the abutting member 30 is located outside the guiding channel 41, a rotation groove 21 is formed on the surface of the rotating member 20, and a transmission pin 33 is arranged on the side of the sliding block 31 facing the rotating member 20.

[0060] Among them, the fixed bracket 40 can be made of metal or high-strength plastic. Its guiding channel 41 is a straight groove to ensure that the slider 31 slides only radially. The slider 31 is movably embedded in the guiding channel 41. The slider 31 and the abutting block can be an integrally formed structure or a detachable connection structure. The guiding channel 41 extends along the radial direction of the rotating member 20. For example, a T-shaped groove design can be adopted, which not only allows the slider 31 to slide freely but also prevents it from coming out.

[0061] Specifically, when the rotating member 20 rotates, the slider 31 is driven to move along the guiding channel 41 through the cooperation of the transmission pin 33 and the rotating groove 21. Due to the linear constraint of the guiding channel 41, multiple sliders 31 can synchronously generate radial displacements, driving each abutting block to form a symmetric clamping action.

[0062] When multiple abutting members 30 are provided, the fixed bracket 40 is correspondingly provided with multiple guiding channels 41, and each slider 31 is correspondingly arranged in a guiding channel 41. For example, when 4 abutting members 30 are provided, the fixed bracket 40 is provided with 4 guiding channels 41. At this time, the fixed bracket 40 can be designed into a cross shape, and 4 guiding channels 41 are correspondingly formed and distributed in central symmetry.

[0063] Combined with Figures 4 to 9 As shown, in an embodiment of the present invention, a limiting groove 42 communicating with the guiding channel 41 is formed on the surface of the fixed bracket 40. The limiting groove 42 extends along the radial direction of the rotating member 20. The transmission pin 33 movably passes through the limiting groove 42 and is embedded in the rotating groove 21;

[0064] Among them, the limiting groove 42 is formed on the surface of the fixed bracket 40 and communicates with the guiding channel 41. Its extending direction is consistent with the radial direction of the rotating member 20. It can be made by milling or injection molding processes and is used to limit the lateral offset of the transmission pin 33.

[0065] When the transmission pin 33 moves linearly along the limiting groove 42 under the drive of the rotating groove 21, the contact surface between the side wall of the limiting groove 42 and the transmission pin 33 forms a lateral constraint, preventing the trajectory offset caused by the generation of a component force in the circumferential direction of the rotating member 20 by the transmission pin 33. The constraint of the guiding channel 41 on the slider 31 and the constraint of the limiting groove 42 on the transmission pin 33 ensure that the abutting member 30 moves along a predetermined trajectory. In other embodiments, the transmission pin 33 can also be located outside the limiting groove 42, that is, the transmission pin 33 is arranged on the surface of the slider 31 extending outside the guiding channel 41.

[0066] Combined with Figures 4 to 9 As shown, in an embodiment of the present invention, the sides of at least two abutting blocks facing away from or facing the slider 31 are both arc-shaped surfaces, and the arc-shaped surfaces are used to abut against the smart wearable product;

[0067] And / or, a protrusion 34 is provided on the surface of at least one abutting block 32 , and when the abutting block 32 abuts against the smart wearable product, the protrusion 34 is used to embed into the anti-mistake groove provided on the inner surface of the smart wearable product.

[0068] Among them, the surface of the abutment block in contact with the smart wearable product is set to an arc surface. Specifically, an injection molding process can be used to form a continuous arc surface with a preset curvature. The preset curvature can match the curvature of the outer shape of common smart wearable products. During the radial movement of the abutment block along the rotating part 20, the arc surface can disperse the pressure applied to the product through the arc surface contact, avoid local stress concentration, and at the same time increase the contact area between the abutment 30 and the product, thereby improving the charging efficiency. It can be understood that the arc surface can be set on the side of each abutment block away from the slider 31. In this case, when each abutment block moves in the radial direction, it will abut against the inner wall surface of the smart ring 60; when the arc surface is set on the side of each abutment block facing the slider 31, the smart ring 60 is located in the charging position enclosed by each abutment block. When each abutment block moves in the radial direction, it will clamp the outer wall surface of the smart ring 60.

[0069] This surface-to-surface contact method not only increases the contact area between the abutment block and the product, but also compensates for product dimensional errors through the curved surface curvature, ensuring stable radial clamping of smart wearable products of varying diameters. For donut-shaped smart rings, the curved surface forms an enveloping wrap when in contact, ensuring a constant relative position between the charging module and the product's charging port.

[0070] When charging, it is necessary to ensure that the charging module is in close contact with the product, especially when charging the product wirelessly. The fit between the charging module and the product will affect the charging efficiency. Through the above technical solution, this application solves the problem of insufficient contact and fit between the charging module and products of different sizes, ensuring that the charging module is precisely aligned with the product charging interface to maintain stable wireless charging efficiency. The curved surface structure effectively reduces the pressure in the contact area, avoids surface wear of smart wearable products due to local stress concentration, and extends the service life of the product.

[0071] When the side surfaces of the abutment block facing away from or toward the slider 31 are limited or not limited to be arc-shaped surfaces, a protrusion 34 is also provided on the surface of the abutment block 32, wherein the protrusion 34 is made of injection molding or metal inserts. The anti-idiot groove refers to a preset concave structure on the inner surface of the smart wearable product, which can be formed by stamping or laser engraving, and the protrusion 34 is adapted to the anti-idiot groove.

[0072] When contact block 32 contacts the smart wearable device, the engagement of protrusion 34 with the anti-aliasing groove creates a mechanical interlock, restricting circumferential slippage during charging and maintaining spatial alignment between the charging module's wireless coil and the device's power receiving component. Furthermore, the interlocking mechanism of protrusion 34 and the anti-aliasing groove ensures precise positioning of the charging port, effectively preventing poor contact caused by external interference during charging.

[0073] Combine Figures 1 to 3 As shown, in one embodiment of the present invention, the rotating member 20 and the fixed bracket 40 are both arranged in the shell 11, an avoidance hole 113 is opened on the surface of the shell 11, and the supporting block is arranged on the outside of the shell 11. The end of the slider 31 facing away from the fixed bracket 40 passes through the avoidance hole 113 and is connected to the supporting block.

[0074] In this embodiment, the avoidance hole 113 refers to a through-hole formed on the surface of the housing 11, such as a circular or rectangular opening, which allows the slider 31 to penetrate the housing 11 and connect to the external retaining block. The rotating member 20 and the fixed member are disposed within the housing 11, thereby allowing the housing 11 to protect the various components. The connection structure between the slider 31 and the retaining block through the avoidance hole 113 physically isolates the internal transmission mechanism from the external clamping function, maintaining the internal sealing of the housing 11 while allowing the clamping force to act directly on the inner wall of the smart wearable product.

[0075] Combine Figures 1 to 3 As shown, in one embodiment of the present invention, the housing 11 includes a first end 111 and a second end 112 sequentially arranged along the axial direction of the rotating member 20;

[0076] The rotating member 20 and the fixing bracket 40 are both disposed at the first end 111 . The cross-sectional dimension of the first end 111 is smaller than that of the second end 112 . The avoidance hole 113 is opened on the peripheral side surface of the first end 111 .

[0077] The first end 111 refers to the area of the housing 11 axially closest to the mounting location of the smart wearable product, and may be a truncated cone or cylindrical structure. The second end 112 refers to the area of the housing 11 axially distal to the mounting location, and may be a rectangular parallelepiped or disc-shaped structure, with a larger cross-sectional area for accommodating the battery 132 or circuit board. The avoidance hole 113 is a through-hole formed in the sidewall of the first end 111, positioned to correspond to the movement path of the abutment 30, to prevent the housing 11 from interfering with the movement of the abutment 30.

[0078] The size difference between the first end 111 and the second end 112 forms a stepped shape. When the smart wearable product is placed, its edge can rest against the end surface of the second end 112 to obtain support stability. The outer periphery of the smart wearable product is sleeved on the outer periphery of the first end 111, and the first end 111 also provides radial limiting for the product.

[0079] The axially stepped design of the housing 11 creates separate mounting spaces for the mechanical transmission components and the battery 132 module, meeting both transmission accuracy and energy storage requirements within a limited space. The smart wearable product can be stably placed on the stepped housing 11 while charging, improving the product's stability during charging. Furthermore, the housing 11 includes a bottom shell 15, which is detachably connected to the side of the second end 112 facing away from the first end 111, facilitating the installation of various components within the housing 11.

[0080] Combine Figures 1 to 3 As shown, in one embodiment of the present invention, the smart wearable product charging device further includes a battery 132 , which is disposed in the housing 11 and located at the second end 112 ;

[0081] The charging module includes a flexible circuit board 50 and a wireless coil disposed at one end of the flexible circuit board 50 . One end of the flexible circuit board 50 with the wireless coil is attached to the supporting member 30 , and the other end is electrically connected to the battery 132 .

[0082] The second end 112 has a larger cross-sectional area, creating a space for a large-capacity battery 132. The deformability of the flexible circuit board 50 allows the wireless coil to move synchronously with the support member 30. The wireless coil charges the product through an electromagnetic energy conversion component, specifically a flat copper coil, which transmits power wirelessly through magnetic-inductive coupling.

[0083] One end of the flexible circuit board 50 is secured to or within the support member 30 by bonding or snapping, maintaining the wireless coil parallel to the contact surface of the smart wearable device. The other end extends to the second end 112 and connects to the electrodes of the battery 132. When the support member 30 is radially displaced by the rotating member 20, the flexible circuit board 50 bends to offset the displacement, maintaining circuit continuity while preventing the risk of rigid circuit breakage.

[0084] Combine Figures 1 to 3 As shown, in one embodiment of the present invention, the smart wearable product charging device further includes an electric control module 13 and a driving member 12 provided in the housing 11 , and the electric control module 13 includes a distance sensor and a control module 131 ;

[0085] The driving member 12 is connected to the rotating member 20 for driving, and the control module 131 is in communication with both the distance sensor and the driving member 12. The control module 131 adjusts the angle at which the driving member 12 drives the rotating member 20 to rotate according to the size of the smart wearable product collected by the distance sensor.

[0086] Among them, the electronic control module 13 is an electronic system integrating a distance sensor and a control unit, which can be specifically implemented by an embedded circuit board carrying a microprocessor, and is used to receive and process signals and output control instructions. Among them, the driving member 12 can be a stepper motor or a servo motor, and is connected to the rotating member 20 through a gear set or a belt transmission mechanism. Alternatively, a rotating hole can be opened at the bottom of the rotating member 20, and an internal thread or a tooth groove can be provided in the rotating hole, and at the same time, it is matched with the output shaft of the driving member 12 to enable the driving member 12 to directly drive the rotating member 20 to rotate.

[0087] The distance sensor is a detection device for measuring the size of a target object, which can be specifically a laser ranging sensor or an infrared ranging sensor. It is installed at a position facing the inside of the housing 11 where the smart wearable product is placed. For example, the distance sensor can be set on the outer surface of the first end 111 of the housing 11, or it can be set inside the housing 11, and a light-transmitting hole 114 is opened on the surface of the first end 111, and the detection light of the distance sensor is emitted through the light-transmitting hole 114.

[0088] The control module 131 is the core unit for performing logical operations and signal processing, which can specifically include a circuit control board and a single-chip microcomputer or a programmable logic controller arranged on the circuit control board. The built-in algorithm can convert the size data collected by the distance sensor into the rotation angle parameter of the driving member 12.

[0089] To improve the convenience of installing the overall structure of the module, the smart wearable product charging device further includes a support frame 14. The support frame 14 is arranged on the side of the circuit control board facing the fixed bracket 40. The support frame 14 is provided with a plurality of limiting channels and is used for installing the fixed bracket 40 and the driving member 12, and at the same time, it plays a role in avoiding the electronic components on the surface of the circuit control board.

[0090] The present invention also proposes a smart wearable product set, which includes a smart wearable product and a smart wearable product charging device; the specific structure of the smart wearable product charging device refers to the above-mentioned embodiments. Since the smart wearable product set adopts all the technical solutions of all the above-mentioned embodiments of the smart wearable product charging device, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated here one by one.

[0091] Among them, the smart wearable product is installed in the housing 11, and the rotating member 20 rotates to drive at least two abutting members 30 to move radially along the rotating member 20 to abut against the smart wearable product.

[0092] Among them, the smart wearable product set refers to a combined unit including a smart wearable product and a supporting smart wearable product charging device. The smart wearable product can be a smart ring 60, a smart bracelet, etc. The smart wearable product charging device adapts to and is compatible with the charging of smart wearable products of different sizes by utilizing the cooperation of the rotating member 20 and the abutting member 30. At the same time, the clamping function and the charging module are integrated into the same abutting member 30, avoiding the structural redundancy caused by the additional installation of a positioning device.

[0093] Through the above technical solution, the present application solves the problem of poor adaptability between smart wearable products of different sizes and the charging device, eliminates the need to equip multiple charging devices for products of different sizes, and reduces the production cost. When the user replaces products of different sizes, the same charging device can be directly used to complete the clamping positioning and charging operations, improving the usability.

[0094] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the technical concept of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
