[0025] It should be noted that similar reference numerals and letters indicate 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.

[0026] In the related art, since rings with charging functions come in various sizes, to ensure that the ring can be stably placed and effectively contact the charging contacts during charging, the charging case needs to have an inner diameter size that matches the corresponding ring. When the charging case cannot adapt to rings of multiple sizes, users may need to equip different charging cases for different rings, which limits the versatility of the charging case and affects the charging efficiency.

[0027] The wireless charging case provided by the embodiment of the present application forms a ring accommodation space with variable space size through the folding and unfolding of multiple movable blocks, which facilitates the wireless charging case to adapt to rings of different sizes to charge the rings. At the same time, it improves the stability of rings of different sizes placed in the wireless charging case, enhances the versatility of the wireless charging case, and ensures the charging efficiency of rings of different sizes.

[0028] Refer to Figures 1 to 3 , the embodiment of the present application provides a wireless charging case 100 for charging a ring 200. The wireless charging case 100 includes: A housing 1, on which an opening 11 is provided; An electronic control component 2 and a turntable 3, both the electronic control component 2 and the turntable 3 are arranged inside the housing 1, and the electronic control component 2 can drive the turntable 3 to rotate; An adjustment component 4, the adjustment component 4 includes a plurality of movable blocks 41, the turntable 3 is connected to the plurality of movable blocks 41 and can drive the plurality of movable blocks 41 to fold and unfold, so as to form a ring accommodation space opposite to the opening 11 between the plurality of movable blocks 41.

[0029] In the above embodiment, the housing 1 serves as the structure for protecting the external display case of the wireless charging case 100, provides support and protection for the components inside the housing 1, and can ensure the installation stability of the internal components. Refer to Figure 1 And Figure 2, the opening 11 on the housing 1 allows the user to put the ring 200 into or take it out of the wireless charging case 100, making the opening 11 an interface for the interaction between the ring 200 and the wireless charging case 100. The size of the opening 11 can be relatively large, for example, larger than the size of the largest ring among rings of various sizes, so that the opening 11 can provide a passage for rings of different sizes to enter the ring accommodation space.

[0030] See Figure 3 , the electronic control component 2 is the control unit of the wireless charging case 100. The electronic control component 2 can control the rotation of the turntable 3 and the start and stop of the charging process. The turntable 3, as a mechanism for executing the actions of the movable blocks 41, can rotate under the drive of the electronic control component 2 and drive the connected adjustment component to clamp or release the ring 200, so that the wireless charging case 100 can automatically adjust the size of the ring accommodation space to adapt to the charging of rings 200 of different sizes, improving the versatility and automatic charging ability of the wireless charging case 100.

[0031] See Figures 1 to 3 , multiple movable blocks 41 are annularly distributed. The specific number of the movable blocks 41 can be three, four, five, six or more. The closing of the multiple movable blocks 41 can be that the multiple movable blocks 41 approach each other under the drive of the turntable 3 to reduce the size of the ring accommodation space; the unfolding of the multiple movable blocks 41 can be that the multiple movable blocks 41 move away from each other under the drive of the turntable 3 to increase the size of the ring accommodation space; through the closing and unfolding of the multiple movable blocks 41, the adjustment component 4 can flexibly adjust the size of the ring accommodation space under the drive of the turntable 3.

[0032] The ring accommodation space is the specific placement position of the ring in the wireless charging case 100. By adjusting the size of the ring accommodation space, the wireless charging case 100 can adapt to rings of different sizes, ensuring that the ring 200 can be stably placed during the charging process and the charging contacts between the wireless charging case 100 and the ring 200 can be effectively contacted, thereby improving the charging efficiency and stability of the ring.

[0033] At the same time, the ring accommodation space is opposite to the opening 11, enabling the user to conveniently put the ring 200 into or take it out of the wireless charging case 100, improving the convenience of taking and placing the ring 200 during charging.

[0034] In the embodiments of the present application, the ring accommodation space with variable spatial size is formed by the folding and unfolding of multiple movable blocks 41, enabling the spatial size of the ring accommodation space to be flexibly adjusted, facilitating the charging operation of the wireless charging case to adapt to rings 200 of different sizes, ensuring normal contact of the charging contacts, improving the stability of rings 200 of different sizes placed in the wireless charging case 100, enhancing the versatility of the wireless charging case 100, and ensuring the charging efficiency of rings 200 of different sizes. Moreover, the charging operation is simple, and automatic matching charging between the ring 200 and the wireless charging case 100 can be achieved after the ring is placed in the ring accommodation space.

[0035] In addition, when the multiple movable blocks 41 are folded, they can fix the ring 200, enabling the ring 200 to remain fixed while charging, facilitating the carrying of the ring 200, ensuring the stability of rings of different sizes placed in the charging case, and enhancing the versatility and usage efficiency of the wireless charging case 100.

[0036] In some embodiments, referring to Figure 13 , when the multiple movable blocks 41 are in the folded state, the multiple movable blocks 41 can fix the ring 200 to the ring accommodation space; when the multiple movable blocks 41 are in the unfolded state, the multiple movable blocks 41 can release the ring 200.

[0037] In the above embodiments, before the ring 200 is placed in the wireless charging case 100, the multiple movable blocks 41 can be in the unfolded state; when the ring 200 needs to be charged, first place the ring 200 from the opening 11 into the ring accommodation space inside the multiple movable blocks 41, and the multiple movable blocks 41 move closer to each other to switch to the folded state, and the multiple movable blocks 41 can then clamp the ring 200 to fix the ring 200 to the ring accommodation space, facilitating the charging operation of the ring 200; when the multiple movable blocks 41 are folded, the multiple movable blocks 41 will closely surround the ring 200, playing a role of clamping or fixing the ring 200, preventing the ring 200 from moving or shaking during the charging process, helping to maintain good contact between the ring 200 and the charging contacts of the wireless charging case 100, thereby ensuring the charging efficiency and also avoiding damage or loss of the ring 200 due to accidental movement.

[0038] After the ring 200 is fully charged, the multiple movable blocks 41 move away from each other to switch to the unfolded state, and the multiple movable blocks 41 can then release the ring 200, facilitating the removal and use of the ring 200 and making the charging process smoother and more efficient.

[0039] In some embodiments, a connection groove is provided on the turntable 3, and the multiple movable blocks 41 are connected to the connection groove; When the turntable 3 rotates in a first direction, the multiple movable blocks 41 are retracted; when the turntable 3 rotates in a second direction, the multiple movable blocks 41 are extended. The second direction is opposite to the first direction.

[0040] In the above embodiment, the connection slots enable the multiple movable blocks 41 to be stably mounted on the turntable 3, providing structural support for the movement of the multiple movable blocks 41. Furthermore, the connection slots limit the range of motion of the movable blocks 41, preventing them from excessively deflecting or detaching from the turntable 3 during movement, thereby ensuring the stability and reliability of the entire wireless charging box device.

[0041] The multiple movable blocks 41 are connected together by the turntable 3, and the multiple movable blocks 41 can achieve coordinated movement under the drive of the turntable 3. When the turntable 3 rotates in a first direction to bring the multiple movable blocks 41 together, for example, when the turntable 3 rotates in a clockwise direction, the multiple movable blocks 41 can clamp or position the ring 200 placed therein after being retracted, ensuring that the ring 200 maintains a stable position during the subsequent charging process. When the turntable 3 rotates in a second direction to expand the multiple movable blocks 41, for example, when the turntable 3 rotates in a counterclockwise direction, the multiple movable blocks 41 can release the previously clamped ring 200 after expanding, allowing the ring 200 to be smoothly removed from the wireless charging box 100.

[0042] In some embodiments, the movable blocks 41 may be triangular or arc-shaped. The triangular shape allows the multiple movable blocks 41 to maintain a stable relative position during the folding and unfolding process, precisely securing the ring 200 and improving charging efficiency. The arc-shaped shape allows the movable blocks 41 to more closely conform to the circular or oval shape of the ring 200, better fitting the surface of the ring 200 and providing a more uniform securing force, thereby reducing shaking during charging.

[0043] In some embodiments, see Figure 3 The electric control component 2 includes a circuit board 21, which is fixed in the housing 1 and has conductive terminals 211. A charging and transmitting coil is provided on the movable block 41 , and a conducting portion 31 is provided on the turntable 3 . The conducting portion 31 is connected between the conductive terminal 211 and the charging and transmitting coil. The charging and transmitting coil is used to charge the ring 200 .

[0044] In the above embodiment, the circuit board 21 can control the functions of the wireless charging case 100 for storing and charging the ring 200. Fixing the circuit board 21 in the housing 1 not only ensures the stability and safety of the circuit board 21, but also facilitates the fixing and charging of the ring 200. The circuit board 21 supplies electrical energy and control signals to the charging transmitting coil through the conductive terminal 211, thereby realizing the wireless charging function for the ring 200. By arranging the charging transmitting coil on the movable block 41, the position of the charging transmitting coil can be adjusted as the movable block 41 closes and unfolds, so as to better match rings of different sizes and ensure the stability and efficiency during the charging process.

[0045] See Figure 3 , the conduction part 31 serves as a bridge for the charging path connecting the conductive terminal 211 on the circuit board 21 and the charging transmitting coil on the movable block 41, ensuring the smooth transmission of electrical energy and control signals. Since the turntable 3 can drive multiple movable blocks 41 to close and unfold, the conduction part 31 can cooperate with this dynamic change to ensure the stability and reliability of the charging path conduction during the movement of the movable block 41, enhancing the flexibility and adaptability of the wireless charging case 100, so that the wireless charging case 100 can better meet the charging requirements of rings of different sizes.

[0046] In the above embodiment, among the multiple movable blocks 41, a charging transmitting coil can be arranged on one movable block 41 to simplify the structure of the wireless charging case, but it increases the difficulty of aligning the charging transmitting coil with the charging receiving coil on the ring; or a charging transmitting coil can be arranged on each movable block 41, which can improve the alignment efficiency of the charging transmitting coil with the charging receiving coil on the ring and enhance the convenience during the charging of the ring 200.

[0047] In one embodiment, see Figure 4 , the ring 200 includes an inner ring 202, an outer ring 203 and a charging receiving coil 201. The outer ring 203 is sleeved outside the inner ring 202, and the charging receiving coil 201 is arranged between the inner ring 202 and the outer ring 203. Specifically, the circuit diagram of the charging receiving coil 201 can be made on the FPC (flexible printed circuit board) inside the ring, and the circuit diagram of the charging transmitting coil can be made on the flexible circuit board 411 inside the wireless charging case 100. The wireless charging of the ring 200 can be realized by aligning the charging transmitting coil with the charging receiving coil.

[0048] In some embodiments, see Figures 9 to 11 , the conductive terminal 211 includes a conductive elastic sheet, and the conduction part 31 includes an arc-shaped circuit 311 on the side of the turntable 3 close to the circuit board 21, and the conductive elastic sheet abuts against the arc-shaped circuit 311.

[0049] In the above embodiment, the conductive terminal 211 includes two conductive elastic pieces disposed on the circuit board 21. The arc-shaped circuit 311 includes two circular arc-shaped circuits. The two conductive elastic pieces respectively contact the two circular arc-shaped circuits to form the positive and negative poles of the charging path. During the rotation of the turntable 3, the conduction part 31 is driven to rotate. The arc-shaped sliding track presented by the arc-shaped circuit 311 remains opposite to the conductive elastic piece, so that the two conductive elastic pieces can still be in contact with the two circular arc-shaped circuits during the rotation of the turntable 3, ensuring the stable conduction of the charging path.

[0050] In addition, the conductive elastic piece has good elasticity and electrical conductivity, enabling the conductive elastic piece to deform when subjected to an external force and return to its original state after the external force is removed, thus ensuring the stable contact between the conductive elastic piece and the conduction part 31. This not only improves the reliability of the electrical connection but also absorbs and alleviates the minute displacements generated due to the rotation or vibration of the turntable 3, preventing charging interruption or efficiency reduction caused by poor contact.

[0051] In some embodiments, referring to Figures 6 to 8 , a flexible circuit board 411 is provided on the movable block 41. The conduction part 31 includes two circular ring-shaped circuits 312 located on the side of the turntable 3 away from the circuit board 21, and the flexible circuit board 411 is connected to the circular ring-shaped circuits 312.

[0052] The charging transmitting coil is formed on the flexible circuit board 411.

[0053] In the above embodiment, by providing the flexible circuit board 411 on the movable block 41, the flexible circuit board 411 can be deformed adaptively as the movable block 41 moves and will not be damaged due to the movement of the movable block 41. During the folding and unfolding processes of the movable block 41, the flexible circuit board 411 can maintain the continuity and stability of the circuit, thus ensuring that the charging transmitting coil can work continuously and stably. By arranging the circular ring-shaped circuits 312 on the side of the turntable 3 away from the circuit board 21, the effective connection between the circular ring-shaped circuits 312 and the flexible circuit board 411 is ensured; moreover, during the rotation of the turntable 3, regardless of whether the movable block 41 is in the folded position or the unfolded position, the flexible circuit board 411 can maintain a stable electrical connection with the circular ring-shaped circuits 312, improving the reliability and stability of the wireless charging case.

[0054] In addition, by directly forming the charging transmitting coil on the flexible circuit board 411, the integration degree and efficiency of the wireless charging case 100 are improved, enabling the charging transmitting coil to move as the movable block 41 of the flexible circuit board moves. The charging transmitting coil is convenient to maintain its relative position with the charging receiving coil on the ring, thereby improving the charging efficiency and stability.

[0055] In some embodiments, referring to Figures 6 to 8, on one side of the movable block 41 close to the turntable 3, a first positioning member 412 is provided, and at least a part of the flexible circuit board 411 is arranged on the first positioning member 412; On the side of the turntable 3 away from the circuit board 21, an annular groove 32 is provided. The annular circuit 312 is arranged in the annular groove 32. The first positioning member 412 is movably arranged in the annular groove 32, and the flexible circuit board 411 is in contact with the annular circuit 312.

[0056] In the above embodiment, the setting of the first positioning member 412 can position and guide the movable block 41, ensuring that the movable block 41 can be folded and unfolded along a predetermined trajectory during movement. And arranging a part of the flexible circuit board 411 on the first positioning member 412 not only fixes the flexible circuit board 411 on the movable block 41, but also enables the flexible circuit board 411 to move stably with the movable block 41, which helps to reduce the distortion of the flexible circuit board 411 during the movement of the movable block 41.

[0057] See Figure 8 , the setting of the annular groove 32 provides a spatial path for accommodating and guiding the first positioning member 412 on the turntable 3, enabling the first positioning member 412 to slide along the annular groove 32 when the turntable 3 rotates, thereby guiding the movable block 41 to be stably folded and unfolded, and at the same time ensuring that the flexible circuit board 411 and the annular circuit 312 can maintain an effective electrical connection.

[0058] In one embodiment, the annular groove 32 includes two parallel and non-intersecting groove rails, so that the two first positioning members 412 at the bottom of the movable block 41 can slide in the two groove rails respectively to maintain the conduction between the annular circuit 312 and the flexible circuit board 411. And the annular circuit 312 is connected to the arc-shaped circuit 311, thereby realizing the smooth conduction between the circuit board, the conduction part 31 on the turntable and the flexible circuit board 411.

[0059] In some embodiments, see Figure 10 , an identification sensor 33 is provided on the turntable 3, and the identification sensor 33 is electrically connected to the electronic control component 2; The identification sensor 33 is used to identify the ring accommodation state of the ring accommodation space.

[0060] In the above embodiment, the identification sensor 33 can be a distance sensor or a pressure sensor. The ring accommodation state of the ring accommodation space includes a vacant state and a storage state. When no ring is placed in the ring accommodation space, the identification sensor 33 can identify that the ring accommodation space is in the vacant state; and when a ring is placed in the ring accommodation space, the identification sensor 33 can identify that the ring accommodation space is in the storage state, and then the movable block 41 can be started to be folded to facilitate the fixing and charging of the ring.

[0061] In this embodiment, the electrical connection between the identification sensor 33 and the electronic control component 2 enables data transmission and control signal interaction between the identification sensor 33 and the electronic control component 2. The electronic control component 2 can control the turning on or off of the charging transmitting coil according to the ring accommodation state identified by the identification sensor, and adjust charging parameters, etc., ensuring that the wireless charging case can perform intelligent charging control according to the actual state of the ring, improving the charging efficiency and safety.

[0062] In some embodiments, referring to Figure 1 , Figure 2 and Figure 5 , a second positioning member 413 is provided on the side of the movable block 41 away from the turntable 3, and a guiding groove 12 is provided on the housing 1. The second positioning member 413 is slidably engaged with the guiding groove 12.

[0063] In the above embodiment, when the turntable 3 rotates counterclockwise or clockwise by a certain angle, the second positioning member 413 at the top of the movable block 41 can move along the guiding groove 12. The second positioning member 413 and the first positioning member 412 form double-end positioning of the movable block 41, ensuring that the movable block 41 does not shift or shake during the folding and unfolding processes. Moreover, the number of guiding grooves 12 can be the same as the number of movable blocks 41, and one guiding groove 12 corresponds to guiding one movable block 41 to fold or unfold, ensuring that the movable block 41 always folds and unfolds along the path restricted by the guiding groove 12 during movement, improving the accuracy of the movement of the movable block 41.

[0064] In some embodiments, referring to Figure 3 and Figure 12 , the housing 1 includes a first housing 13 and a second housing 14, and the first housing 13 and the second housing 14 are connected relatively; The electronic control component 2 includes a battery 22. The circuit board 21 is fixed to the first housing 13, and the battery 22 is arranged between the circuit board 21 and the first housing 13 and is electrically connected to the circuit board 21; A plurality of guiding grooves 12 are arranged at intervals on the second housing 14.

[0065] In the above embodiment, dividing the housing 1 into two parts, the first housing 13 and the second housing 14, facilitates the assembly and maintenance of the wireless charging case 100. During the production process, the first housing 13 and the second housing 14 can be processed separately, and then the first housing 13 and the second housing 14 are relatively snap-fitted or magnetically attracted and assembled to form a complete housing structure. And fixing the circuit board 21 to the first housing 13 enhances the stability of the circuit board 21 and facilitates the heat dissipation of the circuit board 21.

[0066] Meanwhile, the battery 22 is disposed between the circuit board 21 and the first housing 13 and electrically connected to the circuit board 21, enabling the battery 22 to be adjacent to the circuit board 21 and reducing the length of the connection line between the battery 22 and the circuit board 21.

[0067] See Figure 1 and Figure 2 , a plurality of guiding grooves 12 are spacedly arranged on the second housing 14. By cooperating the guiding grooves 12 with the second positioning members 413 on the movable block 41, precise guiding of the movement of the movable block 41 is achieved. The arrangement of the plurality of guiding grooves 12 can ensure that the movable block 41 maintains a stable trajectory during movement, reducing the risk of reduced charging efficiency or charging failure caused by movement deviation.

[0068] In one embodiment, see Figure 12 , the electronic control assembly 2 includes a counterweight 23 and a driving member 24. The counterweight 23 is connected to the battery 22, for example, by fixing the counterweight 23 to the bottom of the battery 22, which can ensure the placement stability of the wireless charging case 100; while the driving member 24 such as a motor is disposed on the circuit board 21 and is used to drive the turntable 3 to rotate, and the turntable 3 drives the movable block 41 to move, realizing the closing and unfolding of a plurality of movable blocks 41.

[0069] In some embodiments, see Figure 7 , a magnetic member 414 is provided on the movable block 41. The magnetic member 414 is used for magnetic suction cooperation with the magnetic element on the ring 200, so that the ring 200 can be stably adsorbed on the movable block 41, reducing the risk of the ring falling off or shifting due to external forces (such as vibration, collision, etc.), and helping to ensure that the relative position between the ring and the charging transmitting coil remains unchanged during the charging process, thereby improving the charging efficiency.

[0070] In one embodiment, see Figure 7 , a contact sensing member 415 is respectively provided on each movable block 41. The contact sensing member 415 is electrically connected to the driving member 24 of the electronic control assembly 2. When all the contact sensing members 415 sense that the movable block 41 contacts the ring 200, the operation of the driving member 24 is stopped. This avoids damage caused by the movable block 41 clamping the ring 200 excessively.

[0071] In some embodiments, see Figure 13 , the turntable 3 can drive a plurality of movable blocks 41 to close. When the plurality of movable blocks 41 are in a closed state, the plurality of movable blocks 41 block the opening 11, so that when the wireless charging case 100 does not charge the ring 200, the movable blocks 41 can be closed by the rotation of the turntable 3, thereby protecting the charging components and circuits inside the wireless charging case 100, preventing dust, moisture or other foreign objects from entering the wireless charging case 100, and improving the durability and reliability of the wireless charging case 100.

[0072] In one embodiment, referring to Figure 13 Figure 13 the charging process of the wireless charging case of the present application will be described. The initial state of the wireless charging case is that multiple movable blocks 41 are in the unfolded state. Then, the ring is placed into the wireless charging case through the opening, and at this time, there is no need for the ring to be deliberately centered. The internal recognition sensor of the turntable recognizes the ring and activates the driving member to drive the turntable to rotate counterclockwise. The rotation of the turntable drives the movement of each movable block, gradually reducing the size of the ring accommodation space, and the multiple movable blocks 41 gradually turn into the retracted state. During the retraction process of the multiple movable blocks, they gradually approach the ring. When the magnetic member on a certain movable block magnetically attracts the ring, the ring is adsorbed. The multiple movable blocks continue to retract. When all the movable blocks contact the ring, all the contact sensing members such as the flexible pressure sensors inside the movable blocks are sensed. At this time, the driving member is triggered to stop operating, and the multiple movable blocks fix the ring. Then, the battery power supply of the wireless charging case is activated, and the ring is charged through the wireless charging coil. After the charging is completed, the multiple movable blocks can return to the unfolded state to release the ring, for example, by triggering the driving member to act through means such as APP, voice, or button, and the turntable rotates clockwise to make the movable blocks return to the unfolded state.

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.
