[0048] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0049] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0050] In related art, because charging rings come in a variety of sizes, to ensure the rings remain stable and effectively contact the charging contacts during charging, the charging case must have an inner diameter that matches the corresponding ring. However, if the charging case cannot accommodate rings of various sizes, users may need to use different charging cases for different rings, limiting the versatility of the charging case and affecting charging efficiency.

[0051] The wireless charging box provided in the embodiment of the present application forms a ring accommodating space of variable size by folding and unfolding multiple movable blocks, which makes it easy for the wireless charging box 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 box, improves the versatility of the wireless charging box, and ensures the charging efficiency of rings of different sizes.

[0052] Reference Figures 1 to 3 The embodiment of the present application provides a wireless charging box 100 for charging a ring 200. The wireless charging box 100 includes:

[0053] The housing 1 is provided with an opening 11;

[0054] The electric control component 2 and the turntable 3 are both arranged in the housing 1, and the electric control component 2 can drive the turntable 3 to rotate;

[0055] The adjustment component 4 includes a plurality of movable blocks 41 . The turntable 3 connects 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 accommodating space between the plurality of movable blocks 41 opposite to the opening 11 .

[0056] In the above embodiment, the housing 1 serves as a protective structure for the external display of the wireless charging box 100, providing support and protection for the components inside the housing 1, thereby ensuring the installation stability of the internal components. Figure 1 and Figure 2 The opening 11 on the housing 1 allows the user to place the ring 200 in or out of the wireless charging box 100, making the opening 11 an interface for interaction between the ring 200 and the wireless charging box 100. The size of the opening 11 can be larger, for example, larger than the size of the largest ring among multiple sizes, so that the opening 11 can provide a passage for rings of different sizes to enter the ring storage space.

[0057] See also Figure 3 The electronic control assembly 2 is the control unit of the wireless charging box 100. It controls the rotation of the turntable 3 and the start and stop of the charging process. Driven by the electronic control assembly 2, the turntable 3 acts as the mechanism for executing the movements of the movable block 41. This rotation drives the connected adjustment assembly to clamp or release the ring 200, allowing the wireless charging box 100 to automatically adjust the size of the ring storage space to accommodate rings 200 of different sizes, thereby improving the versatility and automated charging capabilities of the wireless charging box 100.

[0058] See also Figures 1 to 3 , multiple movable blocks 41 are distributed in a ring shape, and the specific number of movable blocks 41 can be three, four, five, six or more. The retraction of multiple movable blocks 41 can be that multiple movable blocks 41 are driven by the turntable 3 to approach each other, so as to reduce the size of the ring accommodating space; the expansion of multiple movable blocks 41 can be that multiple movable blocks 41 are driven by the turntable 3 to move away from each other, so as to increase the size of the ring accommodating space; through the retraction and expansion of multiple movable blocks 41, the adjustment component 4 can flexibly adjust the size of the ring accommodating space under the drive of the turntable 3.

[0059] The ring accommodating space is the specific placement position of the ring in the wireless charging box 100. By adjusting the size of the ring accommodating space, the wireless charging box 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 box 100 and the ring 200 can effectively contact, thereby improving the efficiency and stability of the ring charging.

[0060] At the same time, the ring accommodating space is kept opposite to the opening 11, so that the user can easily put the ring 200 into or take it out of the wireless charging box 100, which improves the convenience of taking and placing the ring 200 when charging.

[0061] The embodiment of the present application forms a ring-accommodating space of variable size by folding and unfolding multiple movable blocks 41. This allows the space size of the ring-accommodating space to be flexibly adjusted, facilitating the wireless charging box's adaptation to charging operations for rings 200 of different sizes, ensuring proper contact between the charging contacts, and simultaneously improving the stability of rings 200 of different sizes placed within the wireless charging box 100, enhancing the versatility of the wireless charging box 100 and ensuring charging efficiency for rings 200 of different sizes. Furthermore, the charging operation is simple: once the ring is placed in the ring-accommodating space, the ring 200 and the wireless charging box 100 automatically pair and charge.

[0062] In addition, the multiple movable blocks 41 can fix the ring 200 when folded, so that the ring 200 can remain fixed while charging, making it convenient to carry the ring 200, ensuring the stability of rings of different sizes placed in the charging box, and improving the versatility and usage efficiency of the wireless charging box 100.

[0063] In some embodiments, see Figure 13 When the multiple movable blocks 41 are in the retracted state, the multiple movable blocks 41 can fix the ring 200 to the ring accommodating space;

[0064] When the plurality of movable blocks 41 are in the expanded state, the plurality of movable blocks 41 can release the ring 200 .

[0065] In the above embodiment, before the ring 200 is placed in the wireless charging box 100, the multiple movable blocks 41 are in an expanded state; when the ring 200 needs to be charged, the ring 200 is first placed into the ring accommodating space within the multiple movable blocks 41 through the opening 11, and the multiple movable blocks 41 are moved close to each other to switch to a retracted state, and the multiple movable blocks 41 can clamp the ring 200 to fix the ring 200 to the ring accommodating space, thereby facilitating the charging operation of the ring 200; when the multiple movable blocks 41 are retracted, the multiple movable blocks 41 will tightly 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 box 100, thereby ensuring charging efficiency, and also preventing the ring 200 from being damaged or lost due to accidental movement.

[0066] After the ring 200 is charged, the multiple movable blocks 41 move away from each other to switch to the expanded state, and the multiple movable blocks 41 can release the ring 200, making it easier to take out and use the ring 200, making the charging process smoother and more efficient.

[0067] In some embodiments, a connecting slot is provided on the turntable 3 , and a plurality of movable blocks 41 are connected to the connecting slot;

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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 .

[0074] In the above embodiment, the circuit board 21 controls the wireless charging case 100's ability to store and charge the ring 200. Securing the circuit board 21 within the housing 1 not only ensures the stability and safety of the circuit board 21 but also facilitates the securement and charging of the ring 200. The circuit board 21 provides power and control signals to the charging transmitter coil via the conductive terminals 211, thereby enabling wireless charging of the ring 200. Positioning the charging transmitter coil on the movable block 41 allows it to adjust its position as the movable block 41 expands and contracts, better accommodating rings of varying sizes and ensuring stability and efficiency during charging.

[0075] See also Figure 3 The conductive portion 31 bridges the charging path between the conductive terminals 211 on the circuit board 21 and the charging transmitter coil on the movable block 41, ensuring smooth transmission of power and control signals. Because the turntable 3 can move the multiple movable blocks 41 to collapse and expand, the conductive portion 31 can adapt to this dynamic change, ensuring stable and reliable charging path conduction during the movement of the movable blocks 41. This enhances the flexibility and adaptability of the wireless charging box 100, allowing it to better meet the charging needs of rings of different sizes.

[0076] In the above embodiment, among the multiple movable blocks 41, a charging transmitting coil can be set on one movable block 41 to simplify the structure of the wireless charging box, 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 set on each movable block 41, which can improve the efficiency of aligning the charging transmitting coil with the charging receiving coil on the ring and improve the convenience of charging the ring 200.

[0077] 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 on the outside of the inner ring 202, and the charging receiving coil 201 is set 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 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 box 100. The charging transmitting coil and the charging receiving coil are aligned to achieve wireless charging of the ring 200.

[0078] In some embodiments, see Figures 9 to 11 The conductive terminal 211 includes a conductive spring, and the conductive portion 31 includes an arc-shaped circuit 311 located on a side of the turntable 3 close to the circuit board 21 . The conductive spring abuts against the arc-shaped circuit 311 .

[0079] In the above embodiment, the conductive terminal 211 comprises two conductive springs disposed on the circuit board 21, and the arcuate circuit 311 comprises two circular arcs. The two conductive springs contact the two circular arcs to form the positive and negative poles of the charging path. The rotation of the turntable 3 drives the conductive portion 31 to rotate. The arcuate sliding path of the arcuate circuit 311 remains opposite to the conductive springs, ensuring that the two conductive springs remain in contact with the two circular arcs during the rotation of the turntable 3, ensuring stable conduction of the charging path.

[0080] In addition, the conductive spring has good elasticity and conductivity, so that the conductive spring can be deformed when subjected to external force and return to its original shape after the external force is removed, thereby ensuring stable contact between the conductive spring and the conductive part 31, which not only improves the reliability of the electrical connection, but also absorbs and alleviates the tiny displacement caused by the rotation or vibration of the turntable 3, preventing charging interruption or efficiency reduction due to poor contact.

[0081] In some embodiments, see Figures 6 to 8 A flexible circuit board 411 is provided on the movable block 41 , and the conductive portion 31 includes two ring 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 ring circuit 312 .

[0082] The charging transmitter coil is formed on the flexible circuit board 411 .

[0083] In the above embodiment, a flexible circuit board 411 is provided on the movable block 41. The flexible circuit board 411 is capable of adapting to deformation as the movable block 41 moves and is not damaged by the movement of the movable block 41. This allows the flexible circuit board 411 to maintain circuit continuity and stability during the folding and unfolding of the movable block 41, thereby ensuring that the charging transmitter coil can operate continuously and stably. The annular circuit 312 is arranged on the side of the turntable 3 away from the circuit board 21, ensuring an effective connection between the annular circuit 312 and the flexible circuit board 411. Moreover, during the rotation of the turntable 3, whether the movable block 41 is in the folded or unfolded position, the flexible circuit board 411 can maintain a stable electrical connection with the annular circuit 312, thereby improving the reliability and stability of the wireless charging box.

[0084] In addition, the charging transmitting coil is directly formed on the flexible circuit board 411, which improves the integration and efficiency of the wireless charging box 100, so that the charging transmitting coil can move with the movement of the movable block 41 of the flexible circuit board, and the charging transmitting coil can be easily maintained relative to the charging receiving coil on the ring, thereby improving the charging efficiency and stability.

[0085] In some embodiments, see Figures 6 to 8 A first positioning member 412 is provided on a side of the movable block 41 close to the turntable 3 , and at least a portion of the flexible circuit board 411 is provided on the first positioning member 412 ;

[0086] An annular groove 32 is provided on the side of the turntable 3 away from the circuit board 21 . The annular circuit 312 is provided in the annular groove 32 . The first positioning member 412 is movably provided in the annular groove 32 , and the flexible circuit board 411 contacts the annular circuit 312 .

[0087] In the above embodiment, the provision of the first positioning member 412 positions and guides the movable block 41, ensuring that the movable block 41 can collapse and expand along a predetermined trajectory during movement. Positioning a portion of the flexible circuit board 411 on the first positioning member 412 not only secures the flexible circuit board 411 to the movable block 41 but also enables the flexible circuit board 411 to move stably with the movable block 41, thereby reducing distortion of the flexible circuit board 411 during movement of the movable block 41.

[0088] See also Figure 8 The setting of the annular groove 32 on the turntable 3 provides a spatial path for accommodating and guiding the first positioning member 412, so that the first positioning member 412 can slide along the annular groove 32 when the turntable 3 rotates, thereby guiding the movable block 41 to stably retract and unfold, while ensuring that the flexible circuit board 411 and the annular circuit 312 can maintain effective electrical connection.

[0089] In one embodiment, the annular groove 32 includes two parallel, non-intersecting groove rails, allowing the two first positioning members 412 at the bottom of the movable block 41 to slide within the two groove rails, respectively, to maintain electrical continuity between the annular circuit 312 and the flexible printed circuit board 411. Furthermore, the annular circuit 312 is connected to the curved circuit 311, thereby achieving smooth electrical continuity between the circuit board, the conductive portion 31 in the turntable, and the flexible printed circuit board 411.

[0090] 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;

[0091] The recognition sensor 33 is used to recognize the ring accommodation state of the ring accommodation space.

[0092] In the above embodiment, the identification sensor 33 can be a distance sensor or a pressure sensor, and the ring accommodating state of the ring accommodating space includes an empty state and a storage state. When no ring is placed in the ring accommodating space, the identification sensor 33 can identify that the ring accommodating space is in an empty state; and when a ring is placed in the ring accommodating space, the identification sensor 33 can identify that the ring accommodating space is in a storage state, and can start the movable block 41 to retract, so as to facilitate the fixation and charging of the ring.

[0093] In this embodiment, the electrical connection between the identification sensor 33 and the electronic control assembly 2 enables data transmission and control signal exchange between the two. Based on the ring's placement status as detected by the identification sensor, the electronic control assembly 2 can control the charging transmitter coil's activation and deactivation, as well as adjust charging parameters. This ensures that the wireless charging case intelligently controls charging based on the ring's actual state, improving charging efficiency and safety.

[0094] In some embodiments, see Figure 1 、 Figure 2 and Figure 5 A second positioning member 413 is provided on a side of the movable block 41 away from the turntable 3 , a guide groove 12 is provided on the housing 1 , and the second positioning member 413 is slidably engaged with the guide groove 12 .

[0095] 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 guide slot 12. The second positioning member 413 and the first positioning member 412 form a double-end positioning for the movable block 41, ensuring that the movable block 41 does not deviate or wobble during the folding and unfolding process. Furthermore, the number of guide slots 12 can be the same as the number of movable blocks 41, and each guide slot 12 guides the folding or unfolding of each movable block 41, ensuring that the movable block 41 always folds and unfolds along the path restricted by the guide slots 12 during movement, thereby improving the accuracy of the movement of the movable block 41.

[0096] In some embodiments, see 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 relatively connected;

[0097] The electric control assembly 2 includes a battery 22. The circuit board 21 is fixed to the first housing 13. The battery 22 is disposed between the circuit board 21 and the first housing 13 and is electrically connected to the circuit board 21.

[0098] A plurality of guide grooves 12 are disposed at intervals on the second housing 14 .

[0099] In the above embodiment, the housing 1 is divided into a first housing 13 and a second housing 14, which facilitates assembly and maintenance of the wireless charging box 100. During production, the first and second housings 13, 14 can be processed separately and then snap-fitted or magnetically assembled to form a complete housing structure. The circuit board 21 is secured to the first housing 13, enhancing its stability and facilitating heat dissipation.

[0100] At the same time, the battery 22 is disposed between the circuit board 21 and the first housing 13 and is electrically connected to the circuit board 21 , so that the battery 22 can be close to the circuit board 21 , reducing the length of the connection line between the battery 22 and the circuit board 21 .

[0101] See also Figure 1 and Figure 2 Multiple guide slots 12 are spaced apart on the second housing 14. These slots cooperate with the second positioning members 413 on the movable block 41 to precisely guide the movement of the movable block 41. The provision of multiple guide slots 12 ensures that the movable block 41 maintains a stable trajectory during movement, reducing the risk of reduced charging efficiency or charging failure due to movement deviations.

[0102] In one embodiment, see Figure 12The electronic control component 2 includes a counterweight 23 and a driving component 24. The counterweight 23 is connected to the battery 22. For example, the counterweight 23 is fixed to the bottom of the battery 22 to ensure the placement stability of the wireless charging box 100. The driving component 24, such as a motor, is set on the circuit board 21 and is used to drive the turntable 3 to rotate. The turntable 3 drives the movable block 41 to move, thereby realizing the folding and unfolding of multiple movable blocks 41.

[0103] In some embodiments, see Figure 7 A magnetic part 414 is provided on the movable block 41. The magnetic part 414 is used to magnetically cooperate 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 charging, thereby improving charging efficiency.

[0104] In one embodiment, see Figure 7 Each movable block 41 is provided with a contact sensor 415, which is electrically connected to the driving member 24 of the electronic control assembly 2. When all the contact sensors 415 sense that the movable block 41 is in contact with the ring 200, the driving member 24 stops moving. This prevents the movable block 41 from over-clamping the ring 200 and causing damage.

[0105] In some embodiments, see Figure 13 The turntable 3 can drive the multiple movable blocks 41 to close. When the multiple movable blocks 41 are in the closed state, the multiple movable blocks 41 block the opening 11, so that when the wireless charging box 100 is not charging the ring 200, the movable blocks 41 can be closed by rotating the turntable 3, thereby protecting the charging components and circuits inside the wireless charging box 100, preventing dust, moisture or other foreign matter from entering the wireless charging box 100, and improving the durability and reliability of the wireless charging box 100.

[0106] In one embodiment, see Figure 13The charging process of the wireless charging box of the present application is described. The initial state of the wireless charging box is that the multiple movable blocks 41 are in an unfolded state. Then, the ring is placed into the wireless charging box through the opening. At this time, the ring does not need to be deliberately centered. The recognition sensor inside the turntable recognizes the ring and activates the drive 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 accommodating space, and the multiple movable blocks 41 gradually turn into a retracted state. The multiple movable blocks slowly approach the ring during the retraction process. When the magnetic member on a certain movable block is magnetically attracted to the ring, the ring is adsorbed. The multiple movable blocks continue to retract. When all the movable blocks contact the ring, the flexible pressure sensors and other contact sensing elements inside the movable blocks are all sensed, at which time the drive member is triggered to stop moving, and the multiple movable blocks then secure the ring. The battery of the wireless charging box is then activated to power the ring, and the ring is charged through the wireless charging coil. After charging is completed, the multiple movable blocks can be restored to the unfolded state to release the ring. For example, the drive member is triggered by an APP, voice, button, etc., and the turntable rotates clockwise to restore the movable blocks to the unfolded state.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
