Description

Technical Field

[0001] This utility model relates to the field of charging case technology, and in particular to a smart ring wireless charging case. Background Technology

[0002] Smart rings are wearable devices that have seen rapid development in recent years, integrating health monitoring (such as heart rate, blood oxygen, and body temperature detection) and activity tracking functions. They achieve intelligence through miniature sensors and low-power chips. Traditional smart rings use metal contacts on the inner ring for charging via contact. However, because the contacts are made of stainless steel or nickel-plated copper, there are noticeable protrusions inside the ring, resulting in poor wearing comfort and, more seriously, metal allergies in some users. Currently, there is a gradual transition to wireless charging. Consequently, their charging cases are typically being converted to wireless charging, combining portability and battery replenishment.

[0003] In the current market, smart rings come in various inner diameters to accommodate different finger sizes. Furthermore, smart rings with different shapes and functions also vary in size. Charging cases for smart rings typically use a cylindrical charging base that abuts against the inner circumference of the smart ring for fixation and charging. However, the charging base has a relatively fixed size and cannot be adjusted. This means it can only hold a single size smart ring. Smart rings with an inner diameter smaller than the charging base's diameter cannot fit, while those with an inner diameter larger cannot be secured against the base. As a result, the smart ring may wobble and detach from the charging base during transport, preventing it from charging properly.

[0004] Therefore, in order to meet the charging needs of smart rings of different specifications (inner diameter), manufacturers need to produce a large number of charging cases of different specifications, which is not only costly but also wasteful of resources. Utility Model Content

[0005] The main purpose of this utility model is to provide a wireless charging case for smart rings, which aims to expand the applicability of smart rings of different specifications and sizes, reduce costs, and save resources.

[0006] To achieve the above objectives, this utility model proposes a smart ring wireless charging case, including a case body, a case cover and a wireless charging module. The case body has a storage cavity and a charging base, and is provided with an anti-detachment structure to prevent the smart ring from leaving the wireless charging range.

[0007] In one possible implementation, the charging dock has a cylindrical structure, and a wireless charging area is provided on the side of the charging dock.

[0008] The anti-detachment structure is located on the side of the charging base and can abut against the inside of the smart ring.

[0009] In one possible implementation, the anti-detachment structure includes a limiting rod, a limiting head located at one end of the limiting rod, and a retaining ring disposed on the limiting rod, and the charging base is a hollow structure;

[0010] The limiting rod is embedded in the charging base and slidably connected to the charging base. The end of the limiting rod away from the limiting head extends into the hollow area of ​​the charging base. The retaining ring is located in the hollow area of ​​the charging base, and an elastic element is provided between the retaining ring and the inner wall of the charging base.

[0011] The limiting head extends out of the side of the charging base.

[0012] In one possible implementation, the anti-detachment structure includes an elastic retaining washer located inside the compartment cover, the elastic retaining washer being able to abut against the side of the smart ring facing the compartment cover.

[0013] In one possible implementation, the wireless charging module includes a wireless charging coil, a control unit, and a power supply battery located inside a storage cavity, wherein the wireless charging coil is located in the wireless charging area.

[0014] In one possible implementation, the storage cavity is provided with a tray for installing the power supply battery and the control unit, and there is a gap between the tray and the bottom of the storage cavity.

[0015] In one possible implementation, the bottom of the storage cavity is provided with a positioning groove for fixing the counterweight, and the positioning groove is provided with a plurality of positioning protrusions for surrounding the counterweight and abutting against the side of the counterweight.

[0016] In one possible implementation, the bottom of the compartment is provided with anti-slip pads.

[0017] In one possible implementation, one side of the bin cover is hinged to the bin body, and the bin cover has an annular fixing groove on the side facing the bin body. An annular positioning ring is embedded in the annular fixing groove, and a magnet is embedded in the annular positioning ring.

[0018] The surface of the chamber is provided with a magnetic structure made of magnetic material for magnetic attraction with a magnet.

[0019] The working principle and beneficial effects of this utility model are as follows:

[0020] By incorporating an anti-detachment structure within the charging chamber, the range of smart rings compatible with the charging base is expanded, allowing smart rings of different inner diameters to be stably placed on the charging base and charged.

[0021] Meanwhile, manufacturers only need to produce one type of charging case to fit smart rings with a certain diameter range (i.e., the size range that the anti-slip structure can fit), thereby reducing production costs and saving resources. Attached Figure Description

[0030] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] Example 1

[0033] like Figure 1-5As shown, this utility model proposes a wireless charging case for smart rings. The main structure includes, but is not limited to, a case body 1, a case cover 2, and a wireless charging module. The case body 1 is also equipped with a charging interface. The case body 1 has a smart ring storage area, a storage cavity (lower hollow area), and a charging base 4. The charging base 4 is located in the smart ring storage area and is used to charge the smart rings. Furthermore, to ensure that smart rings of a certain inner diameter range can be fixed and kept within the charging range of the wireless charging module, this embodiment includes an anti-detachment structure to prevent the smart rings from leaving the wireless charging range.

[0034] Meanwhile, in this embodiment, the charging base 4 is designed as a cylindrical structure, which is the same as the inner ring shape of a conventional smart ring, making it convenient to put the smart ring in. The wireless charging area of ​​the wireless charging module is set on the side of the charging base 4, which works with the wireless charging receiver module of the inner ring of the smart ring to realize wireless charging.

[0035] To facilitate securing the smart ring, this embodiment incorporates an anti-detachment structure on the side of the charging base 4, which abuts against the inner side of the smart ring. Specifically, the anti-detachment structure includes a limiting rod 51, a limiting head 52 at one end of the limiting rod 51, and a retaining ring 53 on the body of the limiting rod 51. The charging base 4 is a hollow structure. The limiting rod 51 is embedded in the charging base 4 and slidably connected to it. The end of the limiting rod 51 away from the limiting head 52 extends into the hollow area of ​​the charging base 4. The retaining ring 53 is located in the hollow area of ​​the charging base 4 and is used to limit the movement distance of the limiting head 52. Furthermore, an elastic element 54 is provided between the limiting head 52 and the outer wall of the charging base 4. The elastic element 54 is sleeved on the limiting rod 51, and the limiting head 52 extends out of the side of the charging base 4. This allows the elastic element 54 (i.e., the spring) to push the limiting head 52 towards the inner ring of the smart ring, where it is fixed and limited by contact with the inner ring. For smart rings with small inner diameters, the elastic element 54 can be compressed to reduce the outward movement distance of the limiting head 52. The displacement distance of the limiting head 52 corresponds to the size range suitable for the inner diameter of the smart ring. Furthermore, the retaining ring 53 is coaxially arranged with the rod body, ensuring that the force of the elastic element 54 is evenly distributed on the limiting rod 51, reducing the angular deviation of the limiting rod 51 during displacement. In this embodiment, a slot is cut into the outer wall of the charging base 4 to accommodate the elastic element 54, reducing the minimum protrusion distance of the limiting head 54. This stabilizes the elastic element 54 and expands the displacement distance of the limiting head 54, thereby improving the inner diameter compatibility range of the smart ring.

[0036] At least two of the aforementioned anti-detachment structures are provided, and they are distributed circumferentially along the side of the charging base 4 to keep the smart ring coaxial with the charging base 4. However, this embodiment does not limit the maximum number of these anti-detachment structures.

[0037] Furthermore, to prevent the smart ring from slipping off the limiting head 52 during transport, the anti-slip structure in this embodiment also includes an elastic limiting washer 24 located inside the cover 2. The elastic limiting washer 24 abuts against the side of the smart ring facing the cover 2. When the cover 2 is closed, the elastic limiting washer 24 applies pressure to the side of the smart ring facing the cover 2, and the elastic deformation after pressure restricts the freedom of movement on that side of the smart ring, keeping it stably positioned within the storage compartment 11 and preventing it from making abnormal noises or slipping out of the wireless charging module's operating range due to shaking.

[0038] The wireless charging module in this embodiment mainly includes a wireless charging coil 32, a control unit, and a power supply battery 31 located inside the storage cavity. The control unit is mainly a PCB with a control chip. The power supply battery 31 supplies power to the smart ring through the wireless charging coil 32, which is located in the wireless charging area.

[0039] To ensure safe use, the storage cavity is equipped with a tray 13 for installing the power supply battery 31 and the control unit, and there is a gap between the tray 13 and the bottom of the storage cavity, which can prevent external collisions from being directly transmitted to the power supply battery and the control unit.

[0040] Simultaneously, utilizing the aforementioned spacing, a positioning groove 14 for fixing and attaching the counterweight can be created at the bottom of the storage cavity. Several positioning protrusions 15 are provided within the positioning groove 14 to surround and abut against the sides of the counterweight. The positioning protrusions 15 reinforce the counterweight placed there, preventing it from wobbling or loosening. This avoids a top-heavy appearance in the charging case after the smart ring is placed inside, providing a better grip, greater stability when placed on a table, and helps maintain the center of gravity of the case body 1 when opening the lid 2. It also improves the directional accuracy of the lid 2, enhancing the user experience.

[0041] In order to improve the anti-slip performance of the bottom of the compartment 1 and to avoid bumps and damage to its appearance, an anti-slip pad 16 is provided at the bottom of the compartment 1 in this embodiment.

[0042] Furthermore, in this embodiment, one side of the cover 2 is hinged to the body 1, enabling the cover 2 to rotate and open. An annular fixing groove 21 is then formed on the side of the cover 2 facing the body 1 to provide a locking structure for the cover 2, maintaining its compact structure. The open design of the annular fixing groove 21 also facilitates production and assembly. An annular positioning ring 22 is embedded within the annular fixing groove 21, through which a magnet 23 is embedded. Simultaneously, a magnet 12 structure made of magnetic material is provided on the surface of the body 1 for magnetic attraction with the magnet 23. When the cover 2 is closed, it automatically locks itself magnetically, and can be easily opened, making operation convenient.

[0043] Example 2

[0044] Based on Example 1, when the smart ring is charged wirelessly, this example can have a polymer material on its inner surface that comes into contact with the user's finger. Since there are no contact points on the inner surface of the ring, it is smooth and flat, which not only improves the comfort of wearing it, but also avoids problems such as metal allergies.

[0045] Furthermore, the wireless charging module in this embodiment can communicate with the matching smart ring using an NFC 2.0 wireless charging module, based on a 13.56MHz frequency, with a maximum power transmission rate of 1W. It also allows for a charging distance of up to 5mm between the charging coil and the smart ring.

[0046] It can be used with smart rings of various inner diameters without changing the position of the charging coil inside the charging case.
