Description

Technical Field

[0001] This disclosure generally relates to the field of mobile device technology. More specifically, this disclosure relates to a ring charging device. Background Technology

[0002] Current smart ring charging case designs generally suffer from insufficient compatibility, the core issue being the over-reliance on fixed-size matching in traditional solutions. This necessitates dedicated charging cases for smart rings of different shapes and sizes. This rigid "one device, one case" design leads to several problems: For users, owning both large and slim rings requires purchasing multiple charging cases, which is space-consuming, prone to confusion and loss during travel, and can lead to incompatibility issues in emergencies. For manufacturers, each new product iteration requires redesigning the charging case, resulting in redundant R&D investment, frequent material switching on production lines, and increased warehousing costs, ultimately impacting the product price and creating a vicious cycle. This design philosophy also results in a large number of redundant accessories being left unused and discarded. For example, if manufacturers include a charging case with each generation of products, users are forced to purchase multiple fully functional charging cases, consuming living space and generating e-waste, fundamentally conflicting with the global advocacy of a circular economy. Therefore, smart ring charging devices urgently need to overcome the technological bottleneck of size compatibility. Utility Model Content

[0029] This disclosure provides a ring charging device that enhances the versatility of the ring charging device with a simple and reliable structure by providing an adjustable charging section that can be adjusted relative to the terminal spacing direction.

[0030] The specific embodiments disclosed herein will now be described in detail with reference to the accompanying drawings.

[0031] See Figure 1 , Figure 1 An exemplary perspective view of a ring charging device according to some embodiments of this disclosure is shown. In this embodiment, the ring charging device includes a mounting base 10 and an adjustable charging section 20. The mounting base 10 is used to releasably secure the ring, and a first charging terminal 101 is also fixedly disposed on the mounting base 10. The adjustable charging section 20 includes a second charging terminal 201, and the adjustable charging section 20 is adjustablely connected to the mounting base 10 along the terminal spacing direction between the first charging terminal 101 and the second charging terminal 201.

[0032] The mounting base 10 serves as a base for supporting and / or securing the ring charging device. It has a bottom surface for placement on a relatively fixed object such as a desktop, or a fixing mechanism that allows it to be fixed to other relatively fixed objects via adhesive, magnetic attraction, or other means. With the help of the mounting base 10, the ring charging device can be securely placed for charging. The mounting base 10 houses a charging module that connects to an external power source to receive power. The charging module includes electronic components such as an inverter. The first charging terminal 101 is electrically connected to the charging module and is exposed relative to the mounting base 10. The adjustable charging section 20 is movably connected to the mounting base 10 via an adjustable connecting mechanism. The adjustable charging section 20 also has a second charging terminal 201, which is electrically connected to the charging module and is exposed relative to the adjustable charging section 20. Both the first charging terminal 101 and the second charging terminal 201 are common power terminals used for external charging connectors, such as pogo pins. Therefore, the exposed first charging terminal 101 and second charging terminal 201 can be electrically connected to the charging connector terminals provided on the ring, and the terminal spacing between the first charging terminal 101 and the second charging terminal 201 can be adjusted by the connection mechanism between the adjustable charging part 20 and the fixed base 10 to adapt to the charging connectors of different rings.

[0033] In this embodiment, the fixing base 10 includes a base 12 and a fixing part 11 protruding from the base 12, with a first charging terminal 101 disposed on the fixing part 11. The fixing part 11 is used to pass through the ring during use to support the ring, and can support the ring together with the adjustable charging part 20, while allowing the first charging terminal 101 and the second charging terminal 201 to be electrically connected to the charging connector. The base 12 is used to support or fix the ring charging device to a relatively fixed object. The fixing part 11 and the base 12 are fixed to each other, and the two can be formed as one piece by molding, or fixed to each other by means of screws or other connecting parts.

[0034] Furthermore, in this embodiment, the adjustable charging part 20 is disposed at the end of the fixing part 11 away from the base 12. In use, the ring is mounted to the adjustable charging part 20 and the fixing part 11 from this end away from the base 12. The user can easily adjust the adjustable charging part 20 at this end to align the positions of the first charging terminal 101 and the second charging terminal 201 with the charging connector terminals of the ring. Those skilled in the art will understand that this disclosure does not limit the specific shape and location of the adjustable charging part 20. In some embodiments not shown, the adjustable charging part 20 is disposed at the position of the fixing part 11 between the aforementioned end and the base 12, or disposed on the base 12, as long as it can move relative to the fixing part 10 and allow the second charging terminal 201 and the first charging terminal 101 to be adjusted to fit the charging connector of the ring.

[0035] See also Figures 2 to 4 , Figure 2 An exemplary exploded view of a ring charging device according to some embodiments of this disclosure is shown. Figure 3 An exemplary cross-sectional view of a ring charging device according to some embodiments of this disclosure is shown. Figure 4 It shows Figure 2An enlarged schematic diagram of part A. In this embodiment, a first locking part 211 and a plurality of second locking parts 111 spaced apart along the terminal spacing direction are respectively formed on the adjustable charging part 20 and the fixing part 11. The first locking part 211 can be unlockably fixed with any of the second locking parts 111. The first locking part 211 and the second locking parts 111 together form a connection mechanism between the adjustable charging part 20 and the fixing base 10, wherein the first locking part 211 is disposed on one of the adjustable charging part 20 and the fixing base 10, and the plurality of second locking parts 111 can be disposed on the other. This disclosure does not limit the specific form and number of the first locking part 211 and the second locking part 111. The first locking part 211 can be formed as a locking pin, a magnetic suction head, a hook, etc., while the second locking part 111 can be formed as a plurality of corresponding locking holes, magnetic suction bases, hook grooves, etc., as long as the first locking part 211 and the second locking part 111 can be unlockably fixed relative to each other.

[0036] Specifically, in such Figures 2 to 4 In the illustrated embodiment, the fixing portion 11 has a locking groove 112 extending along the terminal spacing direction, and a plurality of second locking portions 111 are formed within the locking groove 112. The second locking portions 111 are toothed grooves recessed perpendicular to the terminal spacing direction, and the first locking portions 211 are protrusions that fit the shape of the toothed grooves. The locking groove 112 is formed on the side of the adjustable charging portion 20, extends along the terminal spacing direction, and opens toward the fixing base 10, allowing the open side of the locking groove 112 to move toward the fixing portion 11 until one of the plurality of second locking portions 111 engages with the first locking portion 211 on the fixing portion 11. The locking groove 112 extending along the terminal spacing direction connects a plurality of second locking parts 111 in sequence, so that after the first locking part 211 is unlocked from one of the second locking parts 111, it can move along the locking groove 112 and continue to be unlockably locked with another adjacent locking groove 112. Thus, the position of the first locking part 211 of the adjustable charging part 20 can be continuously adjusted, and after being adjusted to a suitable position, it can be locked at the corresponding second locking part 111.

[0037] like Figures 2 to 4 As shown, the second locking part 111 is recessed outward from the inner wall of the locking groove 112 to form a toothed groove, and the first locking part 211 is formed to cooperate with the toothed groove, so that the second locking part 111 limits the first locking part 211 and can move along the extension direction of the locking groove 112 to unlock the second locking part 111, so that the user can easily adjust its position by moving the adjustable charging part 20 along the direction of the locking groove 112.

[0038] Those skilled in the art will understand that, in this embodiment, to enable the first locking part 211 and the second locking part 111 to unlock relative to each other, the first locking part 211 and / or the second locking part 111 are made of a material capable of elastic deformation. Thus, when the first locking part 211 moves relative to the second locking part 111 along the locking groove 112, the two can be unlocked through elastic deformation, and the locking state is restored when the first locking part 211 moves to align with another second locking part 111. Furthermore, in this embodiment, the spacing between the plurality of second locking parts 111 is set to be equidistant. Further, one side of each of the plurality of second locking parts 111 is provided with a mark 115, which is used to mark the number or relative distance of different second locking parts 111 to accurately measure the adjustment amount. In some embodiments not shown, the plurality of second locking parts 111 are set with a spacing of unequal length, which can be preset according to several different ring sizes to specifically adapt to existing ring products and improve the accuracy of the charging connector for a specific ring.

[0039] See you again Figure 4 In this embodiment, a plurality of second locking portions 111 are respectively formed on both sides of the locking groove 112 perpendicular to the terminal spacing direction, and two first locking portions 211 are respectively formed on both sides of the adjustable charging portion 20 perpendicular to the terminal spacing direction. Specifically, the plurality of second locking portions 111 are all formed as serrated grooves or triangular grooves, and the plurality of serrated grooves or triangular grooves are recessed on the inner walls of both sides of the locking groove 112 perpendicular to the terminal spacing direction. The fixing portion 11 includes a positioning platform 210 extending along the terminal spacing direction. The positioning platform 210 has two side walls opposite each other in the width direction perpendicular to the terminal spacing direction, and at least two first locking portions 211 in the shape of triangular protrusions are respectively formed on the two side walls of the positioning platform 210. The width of the positioning platform 210 along the width direction is adapted to the width of the locking groove 112, so that it can extend into the interior of the locking groove 112. The shape and size of the two protruding first locking parts 211 on its side wall are adapted to the shape and size of the recessed second locking parts 111 formed on the two inner walls of the locking groove 112, so that the two first locking parts 211 can engage with the corresponding second locking parts 111 respectively to form an unlockable lock.

[0040] Those skilled in the art will understand that although the above description presents a scheme in which the first locking part 211 is configured as two opposing triangular protrusions and the second locking part 111 is configured as multiple triangular grooves, this disclosure does not limit the number or specific arrangement of the first locking part 211 and the second locking part 111, as long as they can satisfy the requirement that the adjustable charging part 20 can be adjusted to be connected to the fixed part 11. For example, in some embodiments not shown, only one first locking part 211 is configured, and multiple second locking parts 111 are correspondingly configured only on the inner wall of one side of the locking groove 112. In this case, the overall processing difficulty is lower, and the resistance encountered during adjustment is also smaller. Alternatively, in some other embodiments, more first locking parts 211 are configured to enhance the structural stability after engagement with the second locking parts 111. Or, in some other embodiments, the shape of the first locking part 211 is formed as a semi-circle or arc, or a metal spring or positioning ball is used as the first locking part 211, so that the adjustable charging part 20 can move more smoothly during adjustment. This improves the smoothness of sliding between the first locking part 211 and the second locking part 111 during adjustment, the accuracy of the limit, and the lifespan of the ultimate sliding action.

[0041] Furthermore, a first limiting part 212 and a second limiting part 113 are respectively formed on the adjustable charging part 20 and the fixed part 11. The first limiting part 212 and the second limiting part 113 limit each other relative to each other in a direction perpendicular to the terminal spacing and can move relative to each other in the terminal spacing direction. Thus, when the adjustable charging part 20 is moved for adjustment, the relative movement direction between the adjustable charging part 20 and the fixed part 11 is limited by the cooperation of the first limiting part 212 and the second limiting part 113, thereby reducing the increase in friction or deformation deviation caused by the driving force direction being tilted relative to the terminal spacing direction when the operator manually adjusts the part, and thus reducing the occurrence of jamming during adjustment. In addition, the cooperation of the first limiting part 212 and the second limiting part 113 also enhances the structural stability of the connection between the adjustable charging part 20 and the fixed part 11, which is beneficial to maintaining the stability of the relative position of the first charging terminal 101 and the second charging terminal 201 during charging.

[0042] In this embodiment, the second limiting part 113 is a limiting groove communicating with the locking groove 112, and the first limiting part 212 is a limiting post that matches the shape of the limiting groove. Both the limiting groove and the limiting post extend along the terminal spacing direction, wherein the limiting groove is open towards the fixed base 10 and communicates with the locking groove 112. The limiting post extends towards the adjustable charging part 20, and the positioning platform 210 is formed on one side of the limiting post. The cross-section of the limiting post is approximately square, while the cross-section of the limiting groove is formed to match the shape and size of the limiting post. Thus, when the adjustable charging part 20 is docked with the fixed base 10, the limiting post can be inserted into the limiting groove in a shape-fitting manner, and the positioning platform 210 is also inserted into the inside of the locking groove 112, so that the adjustable charging part 20 and the fixed part 11 can dock in a way that limits relative rotation between them, thereby improving the structural stability after connection.

[0043] See Figure 3 and Figure 5 , Figure 5 An exemplary perspective view of a ring charging device according to some embodiments of this disclosure in use is shown, with the ring to be charged shown in dashed lines. In this embodiment, the ring charging device further includes an elastic locking member 50, which is elastically and repositionably fixed relative to the fixing base 10 for pressing the ring against the charging position. Specifically, one side of the elastic locking member 50 is elastically and repositionably connected to the fixing base 10, and the other side extends parallel to the terminal spacing direction, such that one sidewall of the elastic locking member 50 is partially opposite to the first charging terminal 101 and the second charging terminal 201. Thus, in use, when the ring is fitted onto the outside of the fixing part 11 and the adjustable charging part 20 is adjusted, after the first charging terminal 101 and the second charging terminal 201 are respectively aligned with the terminals in the ring charging connector, the elastic locking member 50 can press the ring towards the first charging terminal 101 and the second charging terminal 201, enhancing the stability of the ring fixation during charging, reducing the probability of the ring becoming misaligned during setting or charging, thereby reducing the probability of reduced charging efficiency or failure due to poor contact.

[0044] In addition, see Figure 6 , Figure 6 An exemplary cross-sectional view of a ring charging device according to some embodiments of this disclosure is shown. The ring charging device may also include more fixing parts 11 and corresponding adjustable charging parts 20. Figure 6In the illustrated embodiment, two fixing portions 11 protrude opposite to each other along the terminal spacing direction, and two adjustable charging portions 20 are respectively disposed at the distal ends of the two fixing portions 11 to be adjustablely connected to the corresponding fixing portions 11. Thus, two rings can be respectively disposed on different fixing portions 11 and adjustable charging portions 20 of the same ring charging device, further increasing the number of rings that can be charged simultaneously. Those skilled in the art will understand that in some embodiments not shown, the fixing base 10 is further provided with more fixing bases 10, which are arranged at a certain angular interval or side-by-side, thereby further increasing the number of rings that can be charged simultaneously.

[0045] See Figure 7 , Figure 7 An exemplary cross-sectional view of a ring charging device according to some embodiments of this disclosure is shown. In this embodiment, the mounting base 10 has two first charging terminals 101 spaced apart along the terminal spacing direction, while the adjustable charging section 20 has two second charging terminals 201 spaced apart along the terminal spacing direction. The two first charging terminals 101 are exposed from opposite sides of the mounting portion 11 of the mounting base 10, and correspondingly, the two second charging terminals 201 are also exposed from opposite sides of the adjustable charging section 20. Furthermore, the distance between the two first charging terminals 101 and the two second charging terminals 201 along the terminal spacing direction is greater than the width of the corresponding ring to be charged. Therefore, this charging device can simultaneously charge two rings by adjusting the charging interface to accommodate two rings of the same size, increasing charging efficiency. This configuration is particularly suitable for meeting the need to charge multiple rings simultaneously, such as in home applications.

[0046] Those skilled in the art will understand that the number of the first charging terminal and the second charging terminal can be set to more, and their arrangement position does not have to be set so that the two charging terminals face opposite directions. For example, in some embodiments not shown, the third first charging terminal is set perpendicular to the exposure direction of the other two charging terminals so as to be exposed from the lateral side of the fixing part, while the third second charging terminal is arranged in a similar manner on the lateral side of the adjustable charging part so as to make the charging device more compact.

[0047] Furthermore, although the above describes a scheme in which a first locking part formed as a protrusion and a first limiting part formed as a limiting post are disposed on a fixed base, and a second locking part formed as a groove and a second limiting part formed as a groove are disposed on an adjustable charging part, the present disclosure does not limit the specific structure of the first locking part, the second locking part, the first limiting part, and the second limiting part. For example, in some embodiments not shown, the first locking part formed as a protrusion and the first limiting part formed as a limiting post are disposed on the adjustable charging part, and correspondingly, the second locking part formed as a groove and the second limiting part formed as a groove are disposed on the fixed part, as long as an adjustable connection structure can be formed between the adjustable charging part and the fixed base. In addition, in some other embodiments, a rotary connection structure may also be provided between the adjustable charging part and the fixed base. For example, a circular or partially circular locking groove is provided in the adjustable charging part, and a circular or partially circular locking post that matches the shape of the locking groove is provided on the fixed part, and a first locking part and a second locking part for locking are respectively provided on the locking groove and the locking post. This allows the locking pin to be inserted into the locking slot along the terminal spacing direction and form an adjustable connection thereto. At the same time, the adjustable charging part can rotate within a certain angle range around the terminal spacing direction to accommodate a wider variety of ring charging interfaces of different shapes.

[0048] The ring charging device according to the embodiments disclosed herein enhances the versatility of the ring charging device with a simple and reliable structure by providing an adjustable charging section that can be adjusted relative to the terminal spacing direction. It is particularly suitable for adapting to the ring sizes of different people in different regions. This greatly saves the trouble of designing adaptations for multiple ring models and reduces the increased costs and resource waste associated with producing corresponding adaptation components.

[0049] While numerous embodiments of this disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of this disclosure. It should be understood that various alternatives to the embodiments of this disclosure described herein may be employed in the practice of this disclosure. The appended claims are intended to define the scope of this disclosure and therefore cover equivalents or alternatives within the scope of these claims.
