Figure 2 yes Figure 1 An exploded view of the overall structure of the revealed charging device from a first angle; Figure 3 yes Figure 1 An exploded view of the overall structure of the revealed charging device from a second angle; Figure 4 yes Figure 1 A schematic diagram of the structure of the first angle of the fixed unit as revealed.

[0035] The charging device 100 includes a fixing unit 10, an electrode 30, and a circuit board 40. The fixing unit 10 covers the electrode 30 and the circuit board 40, effectively protecting them from damage caused by external environmental factors such as dust and moisture, thus extending the service life of the charging device 100. One end of the electrode 30 is fixed to the circuit board 40 by a bracket, ensuring a stable connection between the electrode 30 and the circuit board 40 and preventing poor contact or detachment due to vibration or movement. The other end of the electrode 30 penetrates the outer surface of the fixing unit 10, allowing the electrode 30 to directly contact the external smart ring 200, simplifying the charging docking process.

[0036] Please refer to the following: Figures 4 to 5 , Figure 4 yes Figure 1 A schematic diagram of the structure of the fixed unit 10 at the first angle is shown. Figure 5 yes Figure 1 The diagram shows the structure of the fixing unit 10 from a second angle. The fixing unit 10 includes a first supporting part 101 and a charging post 102. The charging post 102 is mounted on the first supporting part 101. The charging post 102 and the first supporting part 101 can be detachably configured or integrally formed. In this embodiment, the charging post and the first supporting part 101 are integrally formed, which is easy to process and has high structural strength, enabling it to withstand greater external forces.

[0037] The outer surface of the charging post 102 includes a top surface 1021, a planar sidewall 1022, and a curved sidewall 1023. The planar sidewall 1022 is connected to the top surface 1021, and the planar sidewall 1022 has a mounting hole through which the electrode 30 passes, providing a clear docking direction for the smart ring 200, making it easy for users to quickly and accurately align the smart ring 200 with the charging post 102. The curved sidewall 1023 is connected to the planar sidewall 1022. The top surface 1021, the planar sidewall 1022, and the curved sidewall 1023 form the outer surface of the charging post 102, which can accommodate smart rings 200 of different shapes or sizes, improving the compatibility of the smart ring 200.

[0038] Please see Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the overall structure of the charging device from a first angle. Figure 8This is a schematic diagram of the overall structure of the charging device from a second angle; the charging device 1000 includes a charging unit 100 and a smart ring 200. Unlike existing wireless charging methods, which require strict alignment between the transmitter and receiver, smart rings 200 often need to be paired with a single charging unit 100 for charging positioning. This results in multiple smart rings 200 being incompatible with a single charging unit 100, and is also inconvenient to operate, easily leading to low charging efficiency or failure to charge due to misalignment. In this embodiment, the electrode 30 is located on the planar sidewall 1022, which has mounting holes to facilitate contact between the electrode 30 and the electrode 30 of the smart ring 200. Furthermore, the planar sidewall 1022 is designed to be smooth and planar, facilitating alignment between the smart ring 200 and the charging post 102 for a tight fit. The length of the planar sidewall 1022 extending towards the curved sidewall 1023 of the charging post 102 is between 5 mm and 50 mm, with no specific limitation. In this embodiment, the length is 10 mm, which can accommodate smart rings 200 of various sizes, ensuring that smart rings 200 of different shapes and sizes can be stably connected to a charging device 100.

[0039] The circuit board 40 is mounted below the first support portion 101. The circuit board 40 is electrically connected to the electrode 30. The circuit board 40 includes a substrate 401, a charging portion 402, and a discharging portion 403. The charging portion 402 is disposed on one side of the substrate 401. One end of the electrode 30 is electrically connected to the discharging portion 403, and the other end of the electrode 30 is electrically connected to the substrate 401, enabling efficient power transmission. It is understood that the charging portion 402 can be a built-in power supply or a charging interface, and there are no specific limitations. The discharging portion 403 can be a power output module or a discharging interface, and there are no specific limitations.

[0040] The first supporting part 101 includes a first outer wall 1011, a first stepped surface 1012, and a first inner wall 1013. The first outer wall 1011, the first stepped surface 1012, and the first inner wall 1013 are integrally formed, increasing the stability of the structure. The first stepped surface 1012 is an inclined arc surface, and the first outer wall 1011 is connected to one end of the first stepped surface 1012. The first inner wall 1013 is connected to the other end of the first stepped surface 1012, and the first inner wall 1013 and the first outer wall 1011 have a high [gap / distance]. The height difference between the first outer wall 1011 and the first inner wall 1013 forms a first recessed area at the position of the first inner wall 1013. The first recessed area is annular and helps to fix the smart ring 200. When the smart ring 200 is placed on the charging post 102, the smart ring 200 is located entirely on the first inner wall 1013, and one end of the smart ring 200 abuts against the first stepped surface 1012. Since there is a height difference between the first outer wall 1011 and the first inner wall 1013, it plays a fixing and limiting role, which can prevent the smart ring 200 from moving during charging.

[0041] The two electrodes 30 are spaced apart on the planar sidewall 1022, with the distance between them ranging from 10 mm to 50 mm. In this example, the distance between them is 18 mm. This spacing ensures electrical isolation between the electrodes 30 while also accommodating the charging needs of different smart rings 200.

[0042] The electrode 30 is made of a magnetically conductive metallic material, such as iron, nickel, cobalt and their alloys, etc., and there are no specific restrictions. It facilitates electrical conductivity and can also be used for magnetic positioning of the smart ring 200.

[0043] The charging device 100 further includes an upper shell 20, a connecting portion 60, and a lower shell 50. The connecting portion 60 is disposed between the upper shell 20 and the lower shell 50, enabling a rotatable connection between the upper shell 20 and the lower shell 50. When the upper shell 20 is closed, the upper shell 20 and the lower shell 50 are in an interference fit, with the upper shell 20 covering the lower shell 50. When the upper shell 20 is opened, the upper shell 20 and the lower shell 50 form a 90-degree angle, with the opening angle ranging from 0 degrees to 90 degrees, and the upper shell 20 stands upright on the lower shell 50.

[0044] The connecting part 60 can be any structure such as a hinge, universal joint, or sliding pair, and there is no specific limitation. In this embodiment, the connecting part 60 is a hinge, which allows the user to adjust the opening angle of the upper shell 20 according to their needs.

[0045] The lower shell 50 is hollow, and the fixing unit 10 further includes a fixing end 103. The fixing end 103 is embedded in the lower shell 50 to facilitate the tight fitting of the fixing unit 10 and the lower shell 50. The lower surface of the fixing end 103 is provided with the first recessed area.

[0046] Please see Figure 6 , Figure 6 yes Figure 1 The schematic diagram of the structure of the disclosed active unit 70 is shown. The charging device 100 further includes an active unit 70, which includes a second outer wall 701, a second stepped surface 702, and a second inner wall 703: the second stepped surface 702 is an inclined arc surface, the second outer wall 701 is connected to one end of the second stepped surface 702; the second inner wall is connected to the other end of the second stepped surface, and the second inner wall 703 has a height difference with the second outer wall 701 to form a second recessed area at the position of the second inner wall 703.

[0047] The upper shell 20 is hollow, and the movable unit 70 is embedded in the upper shell 20, so that the movable unit 70 can be tightly fitted to the upper shell 20.

[0048] When the upper shell 20 covers the lower shell 50, the first outer wall 1011 and the second outer wall 701 are fitted together, and the first inner wall 1013 and the second inner wall 703 form a cavity. The cavity is the receiving space enclosed by the fixed unit 10 and the movable unit 70. The charging post 102 and the smart ring 200 are installed in the receiving space.

[0049] Compared to existing technologies, by setting electrodes 30 of a metallic magnetic material on the charging device 100, and connecting the electrodes 30 to a magnet to form magnetic electrodes 30, and using magnetically conductive material electrodes for the contacts 201 on the smart ring 200, which can be attracted by the magnet, when the smart ring 200 approaches the charging post 102, the attraction of the magnet will align the contacts 201 on the smart ring 200 with the electrodes 30 of the charging post. Users do not need strict alignment to achieve charging, greatly simplifying the charging process. After the electrodes 30 and contacts 301 come into contact, a closed circuit is formed, and current is directly transmitted through the electrodes 30, avoiding conversion losses in wireless charging and improving charging efficiency. This technical solution supports smart rings 200 of different sizes sharing the same charging stand. Whether it's a small or large ring, stable charging can be achieved through magnetic positioning, reducing the need for users to purchase multiple charging stands and lowering usage costs.

[0050] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
