[0019] It should be understood that the content described in this content section is not intended to limit the key or essential features of the embodiments of this disclosure, nor is it intended to restrict the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

[0026] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0027] It should be noted that the headings of any section / subsection provided herein are not limiting. Various embodiments are described throughout this document, and embodiments of any type may be included under any section / subsection. Furthermore, embodiments described in any section / subsection may be combined in any way with any other embodiments described in the same section / subsection and / or different sections / subsections.

[0028] In the description of embodiments of this disclosure, the term "comprising" and similar terms should be understood as open-ended inclusion, i.e., "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may also be included below. The terms "first", "second", etc., may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0029] As mentioned earlier, conventional portable charging devices are either charging cases or charging docks. Charging cases lack aesthetic appeal when displayed on a desk, while charging docks lack portability. Therefore, conventional portable charging devices struggle to balance desktop aesthetics with the need for portability. Furthermore, conventional portable devices require active positioning with the charging structure, resulting in a less intuitive user experience, and a single charging case or dock cannot accommodate portable devices of different sizes.

[0030] While this design approach ensures compatibility and user experience, it also presents significant production and sales challenges. Firstly, in the production process, separate molds need to be developed and production lines adjusted for each size of portable component, undoubtedly increasing manufacturing complexity and costs. Secondly, in terms of sales and inventory management, merchants need to simultaneously stock and manage multiple charging cases of different sizes, which not only increases warehousing costs but also complicates supply chain management. Furthermore, for consumers, choosing the right charging case for their portable device may become less intuitive, further impacting the purchasing experience. Therefore, this one-to-one compatibility solution, while enhancing product functionality, also introduces additional management costs and challenges to production, sales, and marketing.

[0031] To address, or at least partially address, the aforementioned problems or other potential problems of charging devices for portable components in conventional solutions, embodiments of this disclosure provide a charging device for portable components. In the description of this disclosure, the term "portable component" should be interpreted broadly, intended to cover any miniaturized, user-carryable electronic device or component thereof suitable for power replenishment using the charging device according to embodiments of this disclosure. Although some specific embodiments of this disclosure may be illustrated using a smart ring as an example of a "portable component," this is not intended to limit the scope of protection of the invention to smart rings. Specifically, "portable component" is not limited to ring-shaped devices, but may include, but is not limited to, the following types of devices: wearable devices such as smart rings, smartwatches, fitness trackers / smart bracelets, smart ear-worn devices, smart glasses, or smart jewelry; small portable electronic devices such as electronic trackers / tags, portable medical monitoring devices, small remote controls, electronic styluses, etc.; or other miniaturized, user-carryable electronic products or their detachable charging modules that require charging.

[0032] In this disclosure, the term "axial" refers to a direction or position along or parallel to an imaginary centerline. This centerline is the principal longitudinal axis of the charging device according to embodiments of this disclosure. Therefore, in this disclosure, when describing the relative position or movement between two or more components, the "axial" direction refers to the direction along this centerline, as distinct from the "radial" direction perpendicular to this axis. For example, in conjunction with the description of this disclosure, "axial" herein refers to an imaginary centerline along the thickness direction of the charging device.

[0033] According to the embodiments of this disclosure, the charging device can freely switch between charging case mode and charging base mode, satisfying both the aesthetic appeal of a desktop ornament and the portability for travel and storage. Furthermore, the top cover and base are connected by a flexible connector, facilitating easy opening and closing and allowing the top cover to rotate 360°. The flexible connector also incorporates a built-in connecting cable, achieving a simple and elegant hardware structure. Furthermore, in some embodiments, the charging structure may incorporate a built-in magnetic charging component, making it easier to guide the positioning of portable parts.

[0034] The following will combine Figures 1 to 5 This describes an example structure of a charging device for portable components. According to embodiments of this disclosure, the charging device for portable components generally includes a base 2, a top cover 3, and a flexible connector 1.

[0035] The base 2 includes a charging platform 21 and a charging structure disposed on the charging platform. In some embodiments, the charging platform 21 and the bottom surface 23 are arranged parallel to each other on both sides of the base 2 in the axial direction. The charging structure is coupled to the portable component 1 placed on the charging platform 21 to charge the portable component. In some embodiments, the centerline of the charging structure may be at a certain distance from the centerline of the charging platform 21, that is, the charging structure may be disposed at a position off the centerline of the charging platform 21. In this way, arranging the charging structure on the open charging platform 21 provides more flexible placement space for portable components of different sizes, and is simple and convenient to operate.

[0036] The top cover 3 includes a coupling surface 31, a receiving cavity 32 recessed from the coupling surface 31, and an upper surface 33 axially opposite to the coupling surface 31. In some embodiments, similar to the charging platform 21 and the bottom surface 23, the coupling surface 31 and the upper surface 33 are arranged axially parallel to each other on both sides of the top cover 3. In this way, a simple and symmetrical overall appearance is formed for the base 2 and the top cover 3, respectively.

[0037] The receiving cavity 32 is capable of accommodating at least a portable component. The receiving cavity 32 has an inner conical or partially spherical recess. That is, the inner circumferential surface of the receiving cavity 32 may have an inclined or spherical structure, such that the radial dimension of the opening end of the receiving cavity 32 is greater than the radial dimension of the bottom surface of the receiving cavity 32. In this way, the inclined or spherical inner circumferential surface can provide restraint for the portable component housed therein, thereby improving the reliability of accommodating the portable component. In some embodiments, at least a portion of the inner circumferential surface of the receiving cavity 32 may be supported by an elastically deformable material, thereby facilitating the retention of the portable component therein. Furthermore, in some embodiments, the diameter of the receiving cavity 32 may be larger than the diameter of various sizes of portable components. In this way, the charging case can accommodate portable components of different sizes.

[0038] The flexible connector 1 connects the base 2 and the top cover 3, allowing one of them to flip relative to the other. For example, in some embodiments, the flexible connector 1 can be flexible silicone. Since the opening and closing action of the charging device is a low-frequency operation, the requirement for consistency in opening and closing is not high. In this case, flexible silicone not only easily enables the opening and closing of the top cover 3 and the base 2, but also brings additional practical advantages, allowing connecting cables to be integrated within it, thereby further improving the overall integration of the charging device, which will be further explained below. This design makes the top cover 3 or the base 2 less likely to detach or be lost during flipping, while also adding the function of electrically connecting the electronic components in the top cover 3 and the base 2. This simplifies the structure, improves ease of use and durability, and brings greater flexibility and reliability to the overall product.

[0039] The flexible connector 1 allows one of the base 2 and the top cover 3 to flip relative to the other, thus switching the charging device between a charging case mode and a charging dock mode. In the charging case mode, the coupling surface of the top cover 3 abuts against the charging platform 21 of the base 2. In the charging dock mode, the upper surface of the top cover 3 abuts against the bottom surface of the base 2. That is, with the help of the flexible connecting material, the top cover 3 can flip relative to the base 2, and the base 2 can also flip relative to the top cover 3; the top cover 3 can rotate 0 to 360° relative to the base 2. Figure 3 and Figure 5 This shows the case where the top cover 3 is rotated 180° relative to the base 2. Figure 2 The diagram shows the top cover 3 rotated 360° relative to the base 2. In this way, different charging modes of the device are switched by the different surfaces of the top cover 3 and the base 2 coming into contact with each other.

[0040] like Figure 1As shown, in charging case mode, the charging device is in a closed box state, and can be attached to items such as keychains and handbags as a portable accessory. In this mode, the portable component can be stored inside the charging case (accommodated in the receiving cavity 32) for easy carrying. In charging case mode, by flipping the top cover 3 and the base 2 relative to each other, the charging device can be transformed into a charging base mode. Figure 2 As shown, in charging dock mode, the top cover 3 supports the base 2 to form a desktop ornament. In this way, the charging device can be freely switched between charging box mode and charging dock mode, which not only increases the aesthetics when placed, but also meets the portability needs for travel storage, thus balancing the requirements of "desktop aesthetics" and "travel portability".

[0041] In some embodiments, such as Figure 4 As shown, one end of the flexible connector 1 (hereinafter referred to as the first end) is connected to the outer edge of the base 2 and the side 21 of the charging platform in the axial direction, and the second end is connected to the outer edge of the top cover 3 and the side of the coupling surface 31 in the axial direction. In some embodiments, whether in charging box mode or charging dock mode, the axis of the base 2 coincides with the axis of the top cover 3, and the flexible connector 1 is arranged on the same side of the axial direction of the base 2 and the top cover 3. In charging dock mode, the two ends of the flexible connector 1 are provided with sufficient distance in the axial direction to allow the charging cable to pass through. This design is not only efficient and compact in terms of space utilization, but also performs well in terms of connection stability and reliability, providing users with a stable and durable user experience.

[0042] In some embodiments, as mentioned above, the charging device may further include a connecting cable. The connecting cable is arranged in the flexible connector 1 and is capable of connecting at least the electronic components in the base 2 and the top cover 3. The connecting cable can connect the electronic components in the top cover 3 and the base 2. In this way, the connecting cable is concealed within the flexible connector, making the charging device structure simpler and more elegant, thereby improving reliability and manufacturability.

[0043] In some embodiments, the base 2 may further include a charging magnetic element. The charging magnetic element is disposed within the charging structure and can couple with a magnetic element in the portable component to position the portable component. In this way, automatic alignment and positioning via the magnetic force of the charging magnetic element ensures that the portable component can be quickly and accurately coupled to the charging structure, avoiding problems such as low charging efficiency or inability to charge due to inaccurate positioning.

[0044] In some embodiments, the charging structure may include at least one of a charging protrusion, a charging slot, or a charging surface. In some embodiments, the charging structure may include a charging protrusion projecting outward from the charging platform, such as... Figure 2 As shown. Figure 2The charging protrusion shown may have a columnar structure and is adapted to pass through the portable component 1 placed on the charging platform 21 to charge the portable component. In some embodiments, the height of the charging protrusion may be greater than or equal to the height of the portable component 1 of various sizes. In some embodiments, the height of the receiving cavity 32 may be greater than or equal to the height of the charging protrusion 22 in the axial direction.

[0045] Of course, it should be understood that the charging protrusion in the charging device according to the embodiments of this disclosure may not be limited to... Figure 2 The exemplary structure shown is illustrated. In some alternative embodiments, the charging protrusion may also have any other suitable shape, such as, but not limited to, inclined columnar, conical, truncated conical, hemispherical, and other suitable shapes. Furthermore, the number of charging protrusions may not be limited to one, but may be multiple. In some embodiments, the outer diameter of the charging protrusion 22 may be smaller than the inner diameter of various sizes of portable components. Traditional charging cases or charging docks cannot be compatible with all portable components, requiring the design of docks of different sizes to match different sized portable components. In contrast, by arranging the charging protrusion 22 on the dock, with the outer diameter of the charging protrusion 22 being smaller than the inner diameter of different sized portable components, the charging protrusion can adapt to different sized portable components, satisfying the charging needs of a single dock compatible with different sized portable components, thereby reducing the number of docks that need to be produced and thus reducing production costs.

[0046] In some embodiments, the charging structure may further include a charging slot recessed inward from the charging platform 21. The charging slot can be used to accommodate at least a portion of the portable component 1 for charging. Similar to a charging protrusion, the charging slot may have any suitable structure, which will not be described in detail herein. In some embodiments, the charging structure may further include a charging surface flush with the surface of the charging platform 21. In this way, selection can be made according to different application scenarios and user needs to meet the charging requirements of portable devices and improve charging convenience and efficiency.

[0047] In some embodiments, such as Figure 2 As shown, the charging device can employ a wired charging method. Specifically, in some embodiments, the base 2 may include a pair of charging pins 24 for contacting the charging interface of the portable component to charge the portable component. In some embodiments, the charging pins 24 may have an elongated shape to correspond to the charging interface of the portable component to be charged. It should be understood that the charging pins 24 may also have any other suitable shape corresponding to the charging interface of the portable component.

[0048] In some embodiments, such as the one where the charging structure is a charging protrusion, a pair of charging pins 24 can be arranged along the axial direction of the charging protrusion 22 and spaced apart from each other on the side of the charging protrusion 22 near the flexible connector 1, thereby enabling them to contact the charging interface of the portable component and charge the portable component. In this way, the charging pins 24 directly contact the charging interface of the portable component, reducing energy loss during transmission and improving charging efficiency.

[0049] In some embodiments, the charging device can also employ wireless charging. Specifically, in some embodiments, alternatively or additionally, the base 2 may also include a charging coil. The charging coil can be arranged within the charging structure. For example, the charging coil can be arranged in a charging protrusion, a charging slot, and / or a charging surface. The charging coil can couple with a receiving coil in the portable component to charge the portable component. In this way, charging can automatically begin simply by coupling the portable component to the charging structure, without needing to align it with a charging interface, greatly improving ease of use.

[0050] In some embodiments, the charging device may further include a plurality of mating magnetic elements. The plurality of mating magnetic elements are respectively arranged in the base 2 and the top cover 3. For example, the mating magnetic elements may be arranged in at least one of the coupling surface 31 adjacent to the top cover 3 and the top platform 21 of the base 2; and in at least one of the upper surface 33 adjacent to the top cover 3 and the bottom surface 23 of the base 2.

[0051] In some embodiments, both the coupling surface 31 and the top platform 21 may include mating magnetic elements. In this case, the polarities of the mating magnetic elements on the coupling surface 31 and the top platform 21 near their outer ends may be opposite, thereby attracting each other and keeping the charging device in charging case mode. In some alternative embodiments, one of the coupling surface 31 and the top platform 21 includes a mating magnetic element, and the other includes an iron sheet, thereby achieving a similar effect.

[0052] In some embodiments, similar to the coupling surface 31 and the top platform 21, the upper surface 33 and the bottom surface 23 may both include mating magnetic elements, or one may include a magnetic element and the other may include an iron sheet. With this configuration, the charging device can be held in charging case mode or charging base mode by magnetic attraction, ensuring accurate positioning and convenient opening and closing.

[0053] In some embodiments, the coupling surface 31 of the upper cover 3 has the same shape and area as the charging platform 21, and the upper surface 33 has the same outline as the bottom surface 23. This makes the charging device more symmetrical, simple, and aesthetically pleasing. In some embodiments, the coupling surface 31 and upper surface 33 of the upper cover 3, as well as the charging platform 21 and bottom surface 23 of the base 2, can all have circular surfaces, and the diameter of the coupling surface 31 or the charging platform 21 is larger than the diameter of the upper surface 33 or the bottom surface 23. Furthermore, the circumferential surface of the upper cover 3 or the base 2 can adopt an arc-shaped surface or a sloped transition, thereby improving the portability and aesthetics of the entire charging device. Of course, it should be understood that in some alternative embodiments, the coupling surface 31 and upper surface 33 of the upper cover 3, as well as the charging platform 21 and bottom surface 23 of the base 2, can also have any other suitable shape or structure, which will not be described in detail below.

[0054] In some embodiments, the charging device may further include an energy storage battery. The energy storage battery is disposed in at least one of the base 2 and the top cover 3. That is, the energy storage battery can be disposed in the base 2 or the top cover 3, or simultaneously in both the base 2 and the top cover 3, thereby charging the portable component.

[0055] In some embodiments, a charging port is arranged on the side of the top cover 3 near the flexible connector 1 for connecting to a charging cable. In some embodiments, the flexible connector 1 is a flat cable, and a through hole 11 is arranged on the side near the top cover 3, through which the charging cable can pass and connect to the charging port. In this way, the charging port is arranged on one side of the flexible connector 1, reducing the exposure of the charging port and making the charging case look simpler and more elegant.

[0056] In some embodiments, the charging device may further include a light-transmitting area 6 and an indicator light. The light-transmitting area 6 may be formed on the base 2, and the indicator light is arranged in the base 2 adjacent to the light-transmitting area, thereby indicating the working status of the charging device to the outside through the light-transmitting area. For example, the indicator light can indicate the charging status; an orange indicator light indicates that charging is in progress, and a green indicator light indicates that charging is complete. In this way, an intuitive and convenient way to understand the status of the charging case is provided, thereby improving the user experience and ease of use of the device.

[0057] In some embodiments, the light-transmitting area can be a transparent or semi-transparent area formed on the charging platform 21 of the base 2. In this way, the light-transmitting area can make the display clear and bright, while the semi-transparent area can make the light softer, thus meeting the needs of different scenarios. Furthermore, using a transparent or semi-transparent light-transmitting area can effectively allow the indicator light to show its status while improving the overall waterproof performance of the charging device. In some alternative embodiments, the light-transmitting area may also include a light-transmitting hole.

[0058] Various implementations of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed implementations. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described implementations. The terminology used herein is chosen to best explain the principles, practical applications, or improvements to technology in the market, or to enable others skilled in the art to understand the various implementations disclosed herein.
