[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0021] In the description of the present application, it should be understood that terms such as "first", "second", etc. are only used to distinguish similar objects, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0022] An embodiment of the present application provides an intelligent ring. The intelligent ring can be worn on a user's finger and can be paired with a mobile phone, an AR (Augmented Reality) glasses, a VR (Virtual Reality) glasses, etc. for use. Components such as a touchpad, an IMU (Inertial Measurement Unit), various sensors, a vibration motor, and a display indicator are provided on the intelligent ring. After the intelligent ring is paired with a mobile phone, an AR glasses, or a VR glasses, it can control the switching of the mobile phone menu, the AR glasses interface, or the VR glasses interface to implement operations such as opening and exiting. The intelligent ring can also upload the data collected by various sensors to the mobile phone for analysis to implement various interactive operations such as incoming call reminders. As an interaction method for AR / VR glasses, the intelligent ring can be worn on the finger, is convenient to carry, and can perform complex operations.

[0023] Reference Figure 1 , Figure 1 FIG. is a schematic diagram of the application scenario of the intelligent ring provided by the embodiment of the present application. The intelligent ring provided by the embodiment of the present application can be applied to interact with AR / VR glasses, for example, applied to AR glasses 11. When a user wears the intelligent ring 10 on the finger and wears the AR glasses 11 on the eyes to pair the intelligent ring 10 and the AR glasses 11, the user can make various gesture actions according to needs, such as picking up or placing an item, etc. The inertial measurement sensor on the intelligent ring 10 can track the movement of the user's finger and even the entire arm to control the AR glasses.

[0024] Reference Figure 2 , Figure 2 FIG. is a schematic structural diagram of the intelligent ring provided by the embodiment of the present application. The intelligent ring 10 includes a ring body 100, a first side surface 101, a first receiving coil 103, and a battery 106.

[0025] The ring body 100 can be any annular structure suitable for having an accommodation space inside, and a user can wear it on the finger. The cross-sectional shape of the ring body 100 can be reasonably set according to actual needs. For example, its shape can be oval, circular, polygonal, or other irregular shapes, etc. Optionally, as Figure 2 shown, the ring body 100 can be a circular ring structure. The ring body 100 can be made of materials such as metal and plastic. The ring body 100 has an accommodation space for accommodating various electronic components of the wireless charging device and various sensors, etc.

[0026] At least one battery 106 is provided inside the ring body 100. The battery 106 can be a small-capacity lithium polymer battery, which reduces the volume of the battery and thus saves the internal space of the ring body 100. The battery 106 can be fixed to the back or side of the internal circuit board of the ring body 100 by bonding, such as glue bonding, tape fixing, screwing, such as screw connection, snap structure, etc. By providing the battery 106 inside the ring body 100, the smart ring 10 can work independently, facilitating the user to wear and use it for a long time.

[0027] The ring body 100 encloses a space to facilitate the user to wear it on the finger. The first side surface 101 is an annular surface, and the first receiving coil 103 is arranged along and around the first side surface 101. The first receiving coil 103 is used to receive electrical energy wirelessly. The battery 106 is electrically connected to the first receiving coil 103 so that the first receiving coil 103 provides electrical energy to the battery 106 to maintain the smart ring 10 in a stable working state.

[0028] For the smart ring provided by the embodiment of the present application, by providing the first receiving coil on the ring body, the first receiving coil can receive electrical energy wirelessly. Therefore, the smart ring can charge the battery wirelessly, thus improving the charging convenience of the smart ring.

[0029] Reference Figure 3 , Figure 3 is another structural schematic diagram of the smart ring provided by the embodiment of the present application. The smart ring 10 further includes a second side surface 102 and a second receiving coil 104. The ring body 100 encloses a space that penetrates from the first side surface 101 to the second side surface 102, so that the smart ring 10 forms an annular structure that the user can wear on the finger. Among them, the first side surface 101 and the second side surface 102 are opposite, and both the first side surface 101 and the second side surface 102 are annular surfaces. The second receiving coil 104 is arranged along and around the second side surface 102. The second receiving coil 104 is used to receive electrical energy wirelessly. The battery 106 is used to be electrically connected to the first receiving coil 103 and the second coil 104 so that the first receiving coil 103 and the second receiving coil 104 charge the battery 106.

[0030] It can be understood that by setting the first receiving coil 103 and the second coil 104 at the same time, the battery 106 can be charged by the first receiving coil 103 and the second coil 104 at the same time, thereby improving the charging efficiency.

[0031] Reference Figure 4 , Figure 4Schematic diagram of the parallel connection of the internal coils of the smart ring provided by the embodiment of the present application. The smart ring 10 further includes a wireless charging circuit 105, and the first receiving coil 103 and the second receiving coil 104 are electrically connected to the battery 106 through the wireless charging circuit 105 to deliver electrical energy to the battery 106.

[0032] The first receiving coil 103 and the second receiving coil 104 can be connected in parallel. The first receiving coil 103 and the second receiving coil 104 are respectively electrically connected to different positions of the wireless charging circuit 105, so that the first receiving coil 103 and the second receiving coil 104 can independently charge the battery 106. As long as one receiving coil is aligned with the transmitting coil in the charging base to form a wireless charging loop, the receiving coil can receive energy and start charging the battery 106. If the two coils are simultaneously aligned with two transmitting coils respectively to form two wireless charging loops, so that the two receiving coils can simultaneously charge the battery 106, the charging speed will be doubled, the charging time will be shortened, and the user charging experience will be greatly improved.

[0033] Reference Figure 5 , Figure 5 Schematic diagram of the series connection of the internal coils of the smart ring provided by the embodiment of the present application. The first receiving coil 103 and the second receiving coil 104 can be connected in series and commonly electrically connected to the wireless charging circuit 105, so that the first receiving coil 103 and the second receiving coil 104 simultaneously charge the battery 106. When one of the receiving coils is aligned with the transmitting coil to form a wireless charging loop, the receiving coil can receive energy and start charging the battery 106 to keep the smart ring 10 in stable operation.

[0034] With the above layout method and charging scheme of the receiving coil, as long as any side surface of the smart ring is placed flat on an open charging base, regardless of the placement angle of the smart ring or the front and back of the smart ring, charging can start. The charging base is made into a flat plate structure. When the smart ring is placed horizontally, regardless of the fixing method of the smart ring, it can be prevented from rolling.

[0035] The embodiment of the present application also provides a wireless charging box for wirelessly charging the above smart ring. The wireless charging box is convenient to carry and does not take up space, facilitating the user to charge the smart ring.

[0036] Reference Figure 6 , Figure 6Schematic diagram of the structure of the wireless charging case provided by the embodiment of the present application. The wireless charging case 12 can be an open planar structure. The wireless charging case 12 includes a charging base 121 and a first transmitting coil 124. The charging base 121 is used to carry the ring body 100, and the first transmitting coil 124 is disposed inside the charging base 121 for wirelessly transmitting electrical energy. When the ring body 100 is placed on the wireless charging case 12, when the first side surface 101 or the second side surface 102 of the smart ring abuts against the bearing surface of the charging base 12, the first receiving coil 103 of the smart ring is aligned with the first transmitting coil 124 so that the first receiving coil 103 receives the electrical energy transmitted by the first transmitting coil 124.

[0037] The wireless charging case 12 provided by the present application can cooperate with the smart ring 10 to enable wireless charging of the smart ring 10.

[0038] Reference Figure 7 , Figure 7 Another schematic diagram of the structure of the wireless charging case provided by the embodiment of the present application. The wireless charging case 12 includes a bearing part 122, a first coil part 123 and a second coil part 124. The bearing part 122, the first coil part 123 and the second coil part 124 jointly enclose a groove-shaped accommodating space for accommodating the ring body 100. Among them, the first transmitting coil 125 is disposed in the first coil part 123, and the second transmitting coil 126 is disposed in the second coil part 124. When the ring body 100 is accommodated in the accommodating space of the wireless charging case 12, the first receiving coil 103 of the smart ring is aligned with the first transmitting coil 125 so that the first receiving coil 103 receives the electrical energy transmitted by the first transmitting coil 125; at the same time, the second receiving coil 104 of the smart ring is aligned with the second transmitting coil 126 so that the second receiving coil 104 receives the electrical energy transmitted by the second transmitting coil 126. When the first receiving coil 103 and the second receiving coil 104 are connected in parallel, the charging current can be doubled, the charging speed can be increased, and the charging user experience can be improved.

[0039] By respectively winding wireless receiving coils along the ring on the two side surfaces of the smart ring, regardless of whether the above-mentioned planar charging base or box-shaped charging base is used, there is no need to consider the placement angle of the ring or the front and back of the smart ring, and charging can start, and there is no need to consider the fixing method of the smart ring, so that it can be prevented from rolling. The two receiving coils can be charged in parallel or in series, and the application is flexible. When using the wireless charging case for charging, the double-coil parallel connection method can double the charging current and improve the user charging experience.

Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
