Technical Field
[0001] This utility model relates to the field of smart ring charging devices, and in particular to a multi-size compatible smart ring wireless charging dock with an adaptive positioning mechanism. Background Technology
[0002] With the advancement of technology, wearable devices are becoming increasingly prevalent in daily life, serving as important tools for improving personal health management and facilitating communication and data interconnection. Traditional wearable devices, such as smartwatches and wristbands, are not ideal for certain usage scenarios requiring lightweight design due to their larger size. Therefore, miniaturized smart rings are gradually gaining market attention. As a new type of wearable device, smart rings are typically designed as intricately shaped rings that can be worn on the finger and are equipped with multi-functional sensors for tracking personal physiological data.
[0003] However, due to size limitations, smart rings have significantly restricted charging methods. Common charging methods include: charging interface type, charging dock type, or wireless charging. The interface type requires a charging cable to connect the charger to the interface on the ring; the charging dock type involves placing the ring into a corresponding dock, using metal connectors to electrically connect the ring and the dock for charging. Since both of these methods have exposed charging components, the connectors may age over time, leading to reduced charging efficiency.
[0004] Common wireless charging methods can be further divided into charging bases and charging cases. Charging bases allow you to place the ring on top and charge it using an induction coil. While the sensing range is larger, it's not convenient to carry. Charging cases, on the other hand, minimize the induction coil for easier portability, allowing you to charge the ring while storing it. Therefore, the ring's coil needs to be precisely aligned with the charging case's induction coil to ensure charging efficiency.
[0005] The sensing range of induction coils in the form of charging cases is relatively small. Existing ring charging posts require an inner contour structure to conform to the inner ring of the ring, ensuring the ring fits snugly against the corresponding fixed position of the charging post. This guarantees that the coil inside the ring can be sensed by the coil of the charging post for optimal charging. However, smart rings, to ensure a snug fit, have different inner ring sizes. The inner contour structure means that one type of charging post can only correspond to one specific ring size. Even for the same product, different models require the production of charging posts of corresponding sizes based on the ring dimensions.
[0006] In view of the shortcomings of existing ring charging docks, such as low compatibility with rings of different sizes and the need for individual design, the inventors of this case have been actively and continuously developing utility models that can improve the above problems. Utility Model Content
[0007] The main objective of this invention is to achieve precise alignment between the ring and the charging base using an adaptive positioning mechanism, ensuring that the ring's induction coil is accurately positioned within the charging base's magnetic field. This replaces the existing internal contouring structure, allowing charging posts of the same specification to accommodate different ring models, thereby reducing production costs.
[0008] Another objective of this invention is to utilize the fact that the ring and the charging base have the same curvature on their respective cylindrical surfaces to guide the induction coil areas of the ring and the charging base to overlap. At the same time, the ring's induction coil is located at the center of the magnetic field formed by the charging base, thereby maximizing charging efficiency.
[0009] Another objective of this invention is to provide a charging base with an outer contour structure that corresponds to the periphery of the ring, accommodating rings of different sizes and fixing the relative position of the ring and the charging base. Alternatively, it can be equipped with an elastic part to ensure that the induction coil of the ring fits against the induction coil of the charging base.
[0010] This utility model relates to a multi-size compatible smart ring wireless charging dock, comprising: a charging base, a ring, and a positioning mechanism. The charging base includes: a column, a first coil, and a power supply unit, wherein the column is disposed on the charging base; the first coil is disposed inside the column; and the power supply unit is electrically connected to the first coil to supply power and generate an induced magnetic field.
[0011] The ring is positioned around the periphery of the pillar, and its interior includes a second coil. The direction from the pillar towards the ring is defined as the outer side, and the direction from the ring towards the pillar is defined as the inner side. A positioning mechanism is provided between the charging base and the ring to fix their relative positions. Furthermore, the contact area between the pillar and the ring forms a contact zone, with both the first and second coils adjacent to this contact zone. This allows the induced magnetic field generated by the first coil to induce a current in the second coil, charging the ring.
[0012] In a preferred embodiment of this utility model, the charging base further includes: a peripheral portion and a first curved surface, wherein the peripheral portion is disposed on the charging base outside the ring, such that the ring is located between the peripheral portion and the pillar; and the first curved surface is disposed on the outer surface of the contact area of the pillar.

[0013] In a preferred embodiment of this utility model, the outer periphery, the first curved surface, and the second curved surface together form a positioning mechanism, and the outer periphery can generate a thrust toward the column, pushing the ring to contact the column.
[0014] In a preferred embodiment of this utility model, the charging base further includes a peripheral portion and a first positioning portion. The peripheral portion is disposed on the charging base outside the ring, positioning the ring between the peripheral portion and the pillar. The first positioning portion is disposed on the inner side of the peripheral portion. The ring also includes a second positioning portion disposed on the outer side of the ring. The first and second positioning portions are corresponding external contour structures, forming a positioning mechanism together with the peripheral portion. The peripheral portion can generate a thrust towards the pillar.
[0015] In a preferred embodiment of the present invention, the ring further includes a second curved surface disposed on the inner surface of the ring contact area, the curvature of the second curved surface being the same as the curvature of the cylindrical contact area.
[0016] In a preferred embodiment of this utility model, the charging base further includes: a peripheral portion, a first positioning portion, and a first curved surface. The peripheral portion is disposed on the charging base outside the ring, positioning the ring between the peripheral portion and the pillar. The first positioning portion is disposed on the inner side of the peripheral portion. The first curved surface is disposed on the outer surface of the contact area of the pillar. The ring also includes a second positioning portion and a second curved surface. The second positioning portion is disposed on the outer side of the ring, and the second curved surface is disposed on the inner surface of the contact area of the ring. The first positioning portion and the second positioning portion form an outer contour structure, and the outer contour structure, the first curved surface, and the second curved surface together form a positioning mechanism.
[0017] In a preferred embodiment of this utility model, the charging base further includes: a peripheral portion, a first positioning portion, and an elastic portion. The peripheral portion is disposed on the charging base outside the ring, positioning the ring between the peripheral portion and the pillar. The first positioning portion is disposed on the inner side of the peripheral portion. The elastic portion is disposed on the outer surface of the contact area of the pillar. The ring also includes a second positioning portion disposed on the outer side of the ring. The first positioning portion and the second positioning portion form an outer contour structure as a positioning mechanism.
[0018] Preferably, the thrust can be a contact force or a non-contact force.
[0019] Preferably, the non-contact force can be magnetic.
[0020] The advantage of this invention is that it fixes the relative position of the ring and the charging base by means of a positioning mechanism, so that they form a fixed contact area, and sets the coil inside the ring and the charging base adjacent to the contact area, thereby enabling wireless charging.
[0021] Furthermore, even if the relative positions of the ring and the charging base are misaligned when they come into contact, the same curvature and external contour structure can be used to guide the coil to be in the optimal relative position to charge the ring. Attached Figure Description

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0049] Figures 1 to 10 This is a schematic diagram of an embodiment of the present utility model, as shown below. Figure 1 A three-dimensional schematic diagram of an embodiment of the present utility model, Figure 2 A schematic diagram of the charging base 1 according to the first embodiment of this utility model and Figure 3 As shown in the top view of the first embodiment of the present invention, the multi-size compatible smart ring wireless charging base of the present invention includes: a charging base 1, a ring 2, and a positioning mechanism. The charging base 1 includes: a column 11, a first coil 111, and a power supply unit 10. The column 11 is disposed on the charging base 1; the first coil 111 is disposed inside the column 11; and the power supply unit 10 is electrically connected (not shown in the figure) to the first coil 111, and can be connected to an external power source to store power for generating an induced magnetic field, or the external power source can directly supply power through the power supply unit 10.
[0050] like Figure 4 for Figure 1 As shown in the cross-sectional schematic diagram of the first embodiment of this utility model in the IV-IV direction, the ring 2 is disposed on the periphery of the column 11, and the interior of the ring 2 includes a second coil 21. A positioning mechanism is provided between the charging base 1 and the ring 2 to fix their relative positions. The portion where the column 11 and the ring 2 contact each other forms a contact area A. Both the first coil 111 and the second coil 21 are adjacent to this contact area A, so that the induced magnetic field generated by the first coil 111 can induce a current in the second coil 21 to charge the ring 2.
[0051] like Figure 1 as well as Figure 4 As shown, the charging base 1 further includes: a peripheral portion 12 and a first curved surface 112, wherein the peripheral portion 12 is disposed on the charging base 1 outside the ring 2, such that the ring 2 is located between the peripheral portion 12 and the column 11; and the first curved surface 112 is disposed on the outer surface of the contact area A of the column 11.

[0053] Specifically, since the curvatures of the first curved surface 112 and the second curved surface 22 are the same or approximately the same, when the ring 2 is pushed by the outer portion 12 to contact the cylinder 11, it will be guided by the first curved surface 112 and the second curved surface 22 in the contact area A, causing the second coil 21 to approach the first coil 111. When the contact area A deviates from the default position, the contact area A of the ring 2 will be guided back by the first curved surface 112 and the second curved surface 22 by the thrust generated by the outer portion 12, thereby causing the second coil 21 to approach the first coil 111.
[0054] At the same time, the first coil 111 and the second coil 21 are superimposed and their coil planes are parallel to each other. The second coil 21 uses the induced magnetic field generated by the first coil 111 to generate an induced current, thereby charging the ring 2.

[0056] like Figure 7 As shown in the schematic diagram of the second embodiment of this utility model, when the ring 2 can be fixed in relative position with the outer periphery 12 by the outer contour structure B, when the ring 2 is pushed by the outer periphery 12 to contact the column 11, the first coil 111 and the second coil 21 will overlap and be parallel to each other in their normal directions. The second coil 21 uses the induced magnetic field generated by the first coil 111 to form an induced current, thereby charging the ring 2.
[0057] like Figure 8 As shown in the top view of the third embodiment of the present invention, the ring 2 also includes a second curved surface 22, which is disposed on the inner surface of the contact area A of the ring 2. The curvature of the second curved surface 22 is the same as the curvature of the outer surface of the cylinder 11.
[0058] like Figure 9 As shown in the top view of the fourth embodiment of the present invention, the charging base 1 further includes: a peripheral portion 12, a first positioning portion 121, and a first curved surface 112. The peripheral portion 12 is disposed on the charging base 1 outside the ring 2, so that the ring 2 is located between the peripheral portion 12 and the column 11. The first positioning portion 121 is disposed on the inner side of the peripheral portion 12.

[0060] like Figure 6 As shown in the top view of the fifth embodiment of this utility model, the charging base 1 further includes: a peripheral portion 12, a first positioning portion 121, and an elastic portion 113. The peripheral portion 12 is disposed on the charging base 1 outside the ring 2, such that the ring 2 is located between the peripheral portion 12 and the pillar 11. The first positioning portion 121 is disposed on the inner side of the peripheral portion 12.

The ring 2 also includes a second positioning portion 23 disposed on the outer side of the ring 2. The first positioning portion 121 and the second positioning portion 23 form an outer contour structure B as a positioning mechanism.
[0061] In detail, the column 11 conforms to the ring 2 of different styles and inner curvatures by the deformation of the elastic part 113, thereby shortening the distance between the first coil 111 and the second coil 21 to improve charging efficiency.
[0062] Preferably, the thrust can be a contact force or a non-contact force.
[0063] Preferably, the non-contact force can be magnetic.
[0064] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention.
