[0055] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0056] In the related art, most smart rings adopt an integrated design, and the ring is an integral and non-detachable structure, resulting in the user being unable to replace the appearance color and material of the ring according to personal preferences or the needs of different occasions. Moreover, as the usage time increases, the surface of the ring may be worn or discolored. The integrated design makes it difficult for the user to repair or replace it, affecting the service life of the product and the user experience.

[0057] When the elastic part 21 of the ring provided in the embodiment of the present application is at different lengths, the position of the limiting part 22 will also change accordingly, so as to realize the adjustment of the connection state between the inner ring 1 and the outer ring 3 of the ring, enabling the user to detach or install the outer ring 3 by himself according to needs, and meeting the usage requirements in different scenarios.

[0058] Refer to Figures 1 to 3 , the embodiment of the present application provides a ring, which includes:

[0059] Inner ring 1, on which a plurality of accommodating grooves 11 are arranged at intervals, and the accommodating grooves 11 have openings facing outward;

[0060] Limiting member 2 and outer ring 3, the limiting member 2 is arranged in the accommodating groove 11, the limiting member 2 includes an elastic part 21 and a limiting part 22, the elastic part 21 has a first length and a second length, and the second length is greater than the first length;

[0061] When the elastic part 21 is in the first length, the limiting part 22 is received in the accommodating groove 11, and the outer ring 3 can be separated from the inner ring 1; when the elastic part 21 is in the second length, the limiting part 22 extends out from the opening to form a limit on the outer ring 3.

[0062] In the above embodiment, the inner ring 1 serves as the basic structural part of the ring, providing a foundation for installing and supporting components such as batteries and circuit boards. A plurality of accommodating grooves 11 are arranged on the inner ring 1 and have openings facing outward. Each accommodating groove 11 can provide an installation space for a limiting member 2, and the opening design of the accommodating groove 11 enables the limiting member 2 to interact with the outer ring 3 from the opening, realizing the functions of limiting or releasing the limit on the outer ring 3.

[0063] See Figure 5 and Figure 6 , as a key component for controlling the connection state between the outer ring 3 and the inner ring 1, the elastic part 21 of the limiting member 2 can change between different lengths, and the position of the limiting part 22 can be adjusted through this elastic deformation. When the elastic part 21 is at different lengths, the position of the limiting part 22 will also change accordingly, so as to realize the adjustment of the connection state between the inner ring 1 and the outer ring 3 of the ring, enabling the user to detach or install the outer ring 3 by himself according to needs, and meeting the usage requirements in different scenarios; at the same time, it is convenient for the repair or replacement of the outer ring 3, and prolongs the service life of the ring.

[0064] See Figure 6 , when the elastic part 21 is at the first length, the limiting part 22 is received in the accommodating groove 11. At this time, the limiting member 2 does not limit the outer ring 3, and the outer ring 3 can be freely removed from the inner ring 1, realizing the separation of the inner and outer rings of the ring, providing flexibility for the combination of the inner and outer rings of the ring for users. Users can disassemble the outer ring 3 according to their own preferences, different occasion requirements, etc., to realize the reorganization of the appearance of the ring, change the appearance color, material and shape of the ring, and meet the diverse usage requirements.

[0065] See Figure 5 , when the elastic part 21 is at the second length, the limiting part 22 extends out of the opening of the accommodating groove 11 to limit the outer ring 3, preventing the outer ring 3 from detaching from the inner ring 1, realizing the fixed connection of the inner and outer rings of the ring, ensuring the stable connection of the inner and outer rings during the use of the ring, and maintaining the integrity of the ring.

[0066] At the same time, the detachable connection between the outer ring 3 and the inner ring 1 enables the ring to be repaired or replaced by replacing the outer ring 3 even if the surface is worn or discolored after long-term use, ensuring the service life of the ring and the user experience, and enabling the ring to continuously meet the user's needs.

[0067] In one embodiment, see Figure 2 and Figure 3 , the ring includes a ring battery 5, a ring circuit board 6 such as an FPC, and a potting colloid 7; when preparing the ring, first paste devices such as the ring battery 5 and the ring circuit board 6 into the inner ring 1 through back glue, and then fill the inner ring 1 with the potting colloid 7 to cure the devices such as the ring battery 5 and the ring circuit board 6. Because of the protection of the potting colloid 7, even if the user disassembles the outer ring 3 and replaces the outer ring 3, the internal devices such as the ring battery 5 and the ring circuit board 6 will not be damaged.

[0068] In some embodiments, when the elastic part 21 is at the first length, the elastic part 21 is in a compressed state; when the elastic part 21 is at the second length, the elastic part 21 is in an extended state.

[0069] In the above embodiment, the elastic part 21 can be compressed or extended when powered on or pressed, and thus the length change adjustment of the elastic part 21 can be realized. When the elastic part 21 is in a compressed state, its length becomes the first length, which is shorter than the extended state (the second length), facilitating the limiting part 22 to be received in the accommodating groove 11, and the outer ring 3 can be freely disassembled and assembled from the inner ring 1; when the elastic part 21 extends to the second length, the elastic part 21 can push or pull the limiting part 22 to extend out of the opening of the accommodating groove 11 to limit the outer ring 3, ensuring the stable connection of the inner and outer rings during the use of the ring.

[0070] In some embodiments, refer to Figure 7 , the elastic part 21 is a shape memory alloy part. The elastic part 21 can be in a first length when electrified, and the elastic part 21 can be in a second length when powered off.

[0071] In the above embodiment, the elastic part 21 and the limiting part 22 are connected. When the elastic part 21 such as a spring is electrified and reaches the contracted state, the elastic part 21 drives the limiting part 22 to retract into the accommodating groove 11 to release the fixation of the outer ring 3. When the elastic part 21 is powered off and returns to the extended state, the limiting part 22 extends out of the accommodating groove 11. At this time, the outer ring 3 can be fixed by the cooperation of the limiting part 22 and the stop surface of the outer ring 3, which simplifies the operations of connecting and separating the outer ring 3 and the inner ring 1.

[0072] In some embodiments, refer to Figure 7 , the limiting member 2 further includes a biasing part 23, and the limiting part 22 can conduct electricity;

[0073] A first metal ring 41 and a second metal ring 42 are arranged at intervals on the inner side of the inner ring 1. One end of the first metal ring 41 away from the limiting part 22 is connected to the elastic part 21. One end of the biasing part 23 is connected to the limiting part 22, and the other end of the biasing part 23 is connected to the second metal ring 42;

[0074] The first metal ring 41 and the second metal ring 42 can electrify the elastic part 21 when connected.

[0075] In the above embodiment, the biasing part 23 connects the limiting part 22 and the second metal ring 42, and can conduct the current path between the limiting part 22 and the second metal ring 42. When it is necessary to electrify the elastic part 21, the limiting part 22, the biasing part 23 and the second metal ring 42 together form a current transmission channel, and then connect the first metal ring 41 and the second metal ring 42 to form a complete circuit. Moreover, the biasing part 23 is arranged on the side of the limiting part 22, which can avoid affecting the movement of the limiting part 22.

[0076] The first metal ring 41 and the second metal ring 42 arranged at intervals can form two ports of the circuit. By controlling the connection state between the first metal ring 41 and the second metal ring 42, the electrification and power-off of the elastic part 21 can be controlled. Moreover, arranging the first metal ring 41 and the second metal ring 42 inside the inner ring 1 can improve the reliability of electrical connection, make the connection between the first metal ring 41 and the second metal ring 42 more firm, not easily affected by the external environment, and reduce the failures caused by loose connection or poor contact.

[0077] In the above embodiments, by connecting the first metal ring 41 to the elastic part 21, an electrical connection channel from the first metal ring 41 to the elastic part 21 is established, enabling current to flow from the first metal ring 41 into the elastic part 21; the biasing part 23 connects the limiting part 22 and the second metal ring 42, and together with the connection between the first metal ring 41 and the elastic part 21, forms a complete electrical connection loop. When the first metal ring 41 and the second metal ring 42 are connected, current can pass through this loop to energize the elastic part 21.

[0078] See Figure 7 , the left end of the elastic part 21 is connected to the first metal ring 41 (which can be the positive electrode); the right end of the elastic part 21 is fixedly welded to the limiting part 22, etc.; the upper side of the limiting part 22 is connected to the second metal ring 42 (which can be the negative electrode), for example, a protruding part that abuts against the second metal ring 42 is provided on the limiting part 22. By conducting or turning off the first metal ring 41 and the second metal ring 42, the contraction and expansion of the elastic part 21 made of shape memory alloy can be controlled.

[0079] In some embodiments, see Figure 4 , Figure 9 and Figure 10 , the inner ring 1 has a through hole inside, and the through hole can accommodate at least a part of the charging base;

[0080] When the charging base is inserted and matched with the ring, the elastic sheet on the charging base can conduct the current path of the elastic part 21.

[0081] In the above embodiments, the through hole inside the inner ring 1 provides a receiving space for the charging base, enabling the charging base to be partially or fully inserted into the inner ring 1. The shape and size of the through hole can match a part of the structure of the charging base, thereby positioning the charging base. When the charging base is inserted into the through hole, it can be accurately positioned at the specified position, ensuring that the elastic sheet on the charging base can be correctly aligned with the elastic part 21 on the ring.

[0082] The elastic sheet on the charging base conducts the current path of the elastic part 21, realizing the electrical connection between the charging base and the ring, enabling current to be transmitted from the charging base to the ring, and providing electrical energy for the elastic part 21 of the ring or other components that need to be charged, such as the battery.

[0083] In some embodiments, the elastic sheet can be designed to have a certain elasticity. When the charging base is inserted into the ring, the elastic sheet is deformed under pressure, contacts the elastic part 21 and conducts the current path; when the charging base is pulled out, the elastic sheet returns to its original state and the current path is disconnected, making the charging operation more convenient and safe. The user can insert or pull out the charging base as needed at any time. Or a conduction button is set to realize the switch of the elastic sheet, thereby controlling the on-off of the power supply of the charging base to the elastic part 21.

[0084] When the outer ring 3 of the ring is replaced, it can start from the state of protruding from the limiting part 22, and the outer ring 3 is in a fixed state. Put the ring on the protrusion in the charging base. At this time, the elastic pieces of the charging base are in contact with the metal rings on the inner ring of the ring respectively, as Figure 9 shown.

[0085] See Figure 10 , in the process from the first step to the second step, by closing the elastic piece, the elastic piece conducts the metal ring. After the elastic part 21 is conducted, it contracts, pulling the limiting part 22 into a contracted state to release the fixation of the outer ring 3. At this time, the user can remove the fixed outer ring 3, as Figure 10 shown in the third step, and then put in the outer ring 3 of other colors or materials again, as Figure 10 shown in the fourth step. Then, by turning off the elastic piece of the charging base, at this time the elastic part 21 returns to the extended state, and the limiting part 22 is pushed out by the elastic part 21, and then the replaced outer ring 3 is fixed, as Figure 10 shown in the fifth step. Finally, separate the ring and the charging base, as Figure 10 shown in the sixth step.

[0086] In some embodiments, see Figure 8 and Figure 9 , a first metal ring group 401 and a second metal ring group 402 are arranged at intervals on the inner side of the inner ring 1, and the limiting member 2 includes a first group of limiting members 201 and a second group of limiting members 202;

[0087] The first metal ring group 401 is connected and cooperated with the first group of limiting members 201, and the second metal ring group 402 is connected and cooperated with the second group of limiting members 202.

[0088] In the above embodiments, the first metal ring group 401 may include a double-ring structure of a first metal ring 41 and a second metal ring 42, and the second metal ring group 402 may also include a double-ring structure of a first metal ring 41 and a second metal ring 42. The first group of limiting members 201 includes a plurality of limiting members 2 arranged at intervals in the circumferential direction of the inner ring 1, and the second group of limiting members 202 may also include a plurality of limiting members 2 arranged at intervals in the circumferential direction of the inner ring 1.

[0089] The connection and cooperation between the two metal ring groups and the corresponding limiting member groups can produce a synergistic effect. Put the ring on the protrusion in the charging base. At this time, the 4 elastic pieces of the charging base are in contact with the 4 metal rings on the inner ring of the ring (for example, the 2 positive electrodes and 2 negative electrodes forming a conduction circuit among the 4 metal rings) respectively, as Figure 9 shown, ensuring the stability of the power supply circuit conduction of the elastic part 21.

[0090] In some embodiments, see Figures 12 to 14, the limiting part 22 is a magnetic part. When the magnetic part is subjected to a magnetic attraction effect, the elastic part 21 can be made to be in the first length;

[0091] When the magnetic attraction effect on the magnetic part is released, the elastic part 21 can return to the second length.

[0092] In the above embodiment, the elastic part 21 and the limiting part 22 can be connected, or they can just be in contact without connection.

[0093] In the above embodiment, the material of the limiting part 22 is a magnetic material. The elastic part 21 is installed at the bottom of the limiting part 22. The limiting part 22 can compress or release the elastic part 21 through telescopic movement. For example, the limiting part 22 can attract with an external magnetic element (such as a magnet or an electromagnet, etc.), and can control the length change of the elastic part 21 through magnetic attraction. This magnetic attraction control method has advantages such as non-contact and rapid response, and can achieve precise control of the telescopic movement of the limiting part 22.

[0094] See Figure 13 , when the magnetic part is subjected to a magnetic attraction effect, the elastic part 21 is compressed and in a contracted state, and the limiting part 22 retracts into the accommodation groove 11 to release the fixation on the outer ring 3. At this time, the elastic part 21 is in the first length. See Figure 12 , when the magnetic attraction effect on the magnetic part is released, the elastic part 21 is released and pushes the limiting part 22 to extend out of the accommodation groove 11. At this time, the elastic part 21 returns to the second length, and the outer ring 3 can be fixed by the cooperation between the limiting part 22 and the stop surface of the outer ring 3. The changes of the elastic part 21 and the limiting part 22 are as Figure 14 shown.

[0095] In some embodiments, see Figure 15 , the inner ring 1 has a through hole inside, and the through hole can accommodate at least a part of the charging base;

[0096] When the charging base is inserted and matched with the ring, the electromagnet on the charging base can be magnetically attracted and matched with the limiting part 22.

[0097] When replacing the outer ring 3 of the ring, it can start from the state where the outer ring 3 extends out of the limiting part 22, and the outer ring 3 is in a fixed state. Put the ring on the protrusion inside the charging base. At this time, the electromagnet of the charging base is magnetically attracted and matched with the limiting part 22 of the ring.

[0098] See Figure 15 , in the process from the first step to the second step, by operating the button or sending an instruction to activate the electromagnet inside the charging base to generate magnetism, the limiting part 22 surrounding the electromagnet is affected by the magnetic force, compresses the elastic part 21, and the limiting part 22 becomes a contracted state, thereby releasing the fixation on the outer ring 3. At this time, due to the electromagnet, the entire inner ring 1 is adsorbed and fixed by the electromagnet, and the user can remove the separated outer ring 3, asFigure 15 The third step shown; then put the outer ring 3 of other colors or materials back in, such as Figure 15 the fourth step shown; then cut off the conduction of the electromagnet, the limiting part 22 in the inner ring 1 loses the restraint of the electromagnet's magnetic force, and is pushed out again by the elastic part 21 to fix the re-inserted outer ring 3, such as Figure 15 the fifth step shown. Finally, separate the ring from the charging base, such as Figure 15 the sixth step shown.

[0099] In some embodiments, referring to Figure 8 , in the axial direction of the ring, a first set of receiving grooves 101 and a second set of receiving grooves 102 are spaced apart on the inner ring 1. The limiting member 2 includes a first set of limiting members 201 and a second set of limiting members 202. The first set of limiting members 201 is disposed in the first set of receiving grooves 101, and the second set of limiting members 202 is disposed in the second set of receiving grooves 102;

[0100] On the inner side of the outer ring 3, a first stop surface 31 and a second stop surface 32 are provided. The first set of limiting members 201 is in limiting cooperation with the first stop surface 31, and the second set of limiting members 202 is in limiting cooperation with the second stop surface 32.

[0101] In the above embodiment, the first set of receiving grooves 101 and the second set of receiving grooves 102 are spaced apart. Both the first set of receiving grooves 101 and the second set of receiving grooves 102 include a plurality of receiving grooves 11 provided in the circumferential direction of the inner ring 1. The first set of receiving grooves 101 and the second set of receiving grooves 102 can be respectively used to accommodate the first set of limiting members 201 and the second set of limiting members 202; both the first set of limiting members 201 and the second set of limiting members 202 include a plurality of the above-mentioned elastic parts 21 and limiting parts 22, which increases the stability of the limit between the inner ring 1 and the outer ring 3. The first stop surface 31 and the second stop surface 32 provide a basis for supporting and limiting the limiting member. When the inner ring 1 and the outer ring 3 move relative to each other, the limiting member and the stop surface interact with each other to ensure the connection stability between the outer ring 3 and the inner ring 1.

[0102] In another embodiment, the limiting member 2 can also include a set of clamping structures and a set of the above-mentioned elastic parts 21 and limiting parts 22, which can also facilitate the disassembly and connection between the outer ring 3 and the inner ring 1.

[0103] The embodiment of the present application also provides a ring charging assembly, which includes a charging base 1000 and a ring 100;

[0104] A protrusion 1001 is provided on the charging base 1000, and the protrusion 1001 is used for plugging and matching with the through hole of the inner ring 1.

[0105] In the above embodiment, referring to Figure 4 and Figure 11, the charging base 1000 includes a lower case 1004 and an upper case 1005. The lower case 1004 and the upper case 1005 are connected to form a receiving cavity, and a charging battery 1006 and a charging circuit board 1007 are disposed in the receiving cavity.

[0106] In one embodiment, a shrapnel bracket 1008 is disposed in the receiving cavity, and a shrapnel 1002 is disposed on the shrapnel bracket 1008. The ring is sleeved on the protrusion 1001 in the charging base. At this time, the shrapnel 1002 of the charging base is in contact with the metal ring of the inner ring of the ring respectively.

[0107] By closing the shrapnel 1002, the shrapnel 1002 conducts the metal ring. After the elastic part 21 is conducted, it contracts, pulling the limiting part 22 into a contracted state to release the fixation of the outer ring 3. At this time, the user can remove the fixed outer ring 3, and then put in another outer ring 3 of a different color or material. Then, by turning off the shrapnel of the charging base, the elastic part 21 returns to the extended state, and the limiting part 22 is pushed out by the elastic part 21, thereby fixing the replaced outer ring 3. Finally, the ring and the charging base are separated.

[0108] In another embodiment, an electromagnet 1003 is disposed in the receiving cavity. The ring is sleeved on the protrusion 1001 in the charging base. At this time, the electromagnet 1003 of the charging base is magnetically coupled with the limiting part 22 of the ring.

[0109] The limiting part 22 surrounding the electromagnet 1003 is affected by the magnetic force, compressing the elastic part 21, and the limiting part 22 becomes a contracted state, thereby releasing the fixation of the outer ring 3. At this time, due to the electromagnet, the entire inner ring 1 is adsorbed and fixed by the electromagnet. The user can remove the separated outer ring 3; then put in another outer ring 3 of a different color or material; then release the conduction of the electromagnet. The limiting part 22 in the inner ring 1 loses the restraint of the magnetic force of the electromagnet and is pushed out again by the elastic part 21 to fix the newly placed outer ring 3. Finally, the ring and the charging base are separated, and the rapid replacement of the outer ring 3 can be realized.

Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
