Description

Technical Field

[0001] This application relates to the field of electronic device auxiliary equipment technology, and in particular to a wireless charging stand. Background Technology

[0002] With the widespread use and diversification of electronic devices, people have increasingly higher demands for ease of use and a tidy living space. Wireless charging stands have emerged to meet this need. Utilizing wireless charging technology, they offer advantages such as no need for cables and ease of use, greatly enhancing the user experience. Currently, wireless charging stands on the market generally employ a design with at least two wireless charging modules to meet users' needs for charging multiple devices. This design allows users to charge frequently used electronic devices such as mobile phones, smartwatches, or Bluetooth headsets simultaneously on a single stand, eliminating the need to occupy multiple sockets or carry multiple chargers, greatly simplifying the charging process and improving convenience.

[0003] To facilitate storage and portability, many wireless charging stands adopt a vertically folding design. This design allows users to fold the stand when not in use, significantly reducing its space occupation and making it easy to store and carry. While the vertical folding design brings many conveniences, it also brings some issues that cannot be ignored. First, the folded stand often exposes the hinge, and small debris such as paper scraps and hair can easily get stuck in the hinge gap. Once these debris enters the hinge gap, it may cause the hinge to malfunction or even jam, seriously affecting the normal use of the stand. Second, the exposed hinge and hinge gap affect the overall flatness of the stand's appearance, reducing the product's aesthetic appeal.

[0034] The second wireless charging module can be rotated to an unfolded position relative to the first wireless charging module. In the unfolded position, the part of the second housing corresponding to the second wireless charging component and the light guide ring are exposed in the first housing.

[0035] This wireless charging stand incorporates a power supply component within either the first or second wireless charging module. When no external power source is connected, the stand can directly power the first and second wireless charging modules via the built-in power supply, facilitating charging of mobile phones, Bluetooth headsets, watches, and other electronic devices outdoors or in environments without external power. Furthermore, the first wireless charging module has a first plate and a rotating portion disposed on the first plate, while the second wireless charging module has a second plate and a mating portion disposed on the second plate. The rotating portion is rotatably connected to the mating portion around the normal of the first plate, allowing the second wireless charging module to rotate relative to the first wireless charging module along the first plate. This allows the rotating portion and mating portion to be concealed in any rotational state, preventing them from being exposed. This avoids issues such as hair, paper scraps, or other debris entanglement between the rotating portion and the mating portion, which could cause rotational difficulties or jamming. It also ensures the overall flatness and consistency of the wireless charging stand, enhancing its aesthetic appeal. Attached Figure Description

[0067] This application proposes a wireless charging stand for wirelessly charging electronic devices such as mobile phones, smartwatches, and Bluetooth headsets.

[0068] In the embodiments of this application, please refer to Figures 1 to 11 The wireless charging stand includes a first wireless charging module 100 and a second wireless charging module 200;

[0069] The first wireless charging module 100 includes a first housing 110 and a first wireless charging component 130 installed in the first housing 110; the first housing 110 has a first plate surface 111 and a rotating part 113 disposed on the first plate surface 111;

[0070] The second wireless charging module 200 includes a second housing 210 and a second wireless charging assembly 240 installed inside the second housing 210. The second housing 210 has a second plate surface 211 that is opposite to and adjacent to the first plate surface 111. The second plate surface 211 is provided with a mating part 220. A rotating part 113 is rotatably connected to the mating part 220 about a first axis, so that the second wireless charging module 200 can rotate relative to the first wireless charging module 100 along the first plate surface 111. The first axis is perpendicular to the first plate surface 111 and the second plate surface 211.

[0071] A power supply component 140 is also installed inside the first housing 110 or the second housing 210. The power supply component 140 is electrically connected to the first wireless charging component 130 and the second wireless charging component 240.

[0072] A wireless charging module is a module that transmits electrical energy to electronic devices through a wireless electrical connection. Typically, a wireless charging module includes a transmitting coil, while the electronic device has a receiving coil. After the receiving coil of the electronic device is aligned with the transmitting coil of the wireless charging module, the wireless charging module supplies power to the electronic device wirelessly through electromagnetic induction or magnetic resonance.

[0073] In this application, both the first wireless charging component 130 and the second wireless charging component 240 have transmitting coils, which are typically made of copper wire (Litz wire) wound in a circular or square shape. The transmitting coils of the first wireless charging component 130 and the second wireless charging component 240 can be designed to correspond to the electronic devices to be charged. For example, both the transmitting coils of the first wireless charging component 130 and the second wireless charging component 240 can be designed to charge mobile phones, or the transmitting coil of the first wireless charging component 130 can be designed to charge mobile phones, and the transmitting coil of the second wireless charging component 240 can be designed to charge electronic devices such as watches and Bluetooth headsets. The size and specific design of the transmitting coils of the first wireless charging component 130 and the second wireless charging component 240 are not specifically limited here. Electronic devices can be directly placed flat on the first wireless charging module 100 and the second wireless charging module 200 for charging. Of course, magnets can also be provided on the outer or inner rings of the first wireless charging component 130 and the second wireless charging component 240 to magnetically attract electronic devices, so that the wireless charging stand can also fix electronic devices when placed vertically or at an angle.

[0074] The power supply unit 140 and the transmitting coils of the first wireless charging component 130 and the second wireless charging component 240 can be electrically connected via wires. Alternatively, they can be electrically connected using PIN pins and conductive rings when necessary. Since the first wireless charging component 130 and the second wireless charging component 240 are electrically connected to the power supply unit 140, they can share a single main control board (main control chip). The drive circuits for the first wireless charging module 100 and the second wireless charging module 200 are located on this main control board. Alternatively, in some embodiments, each of the first wireless charging component 130 and the second wireless charging component 240 may have its own main control chip.

[0075] The first surface 111 and the second surface 211 refer to planes. Therefore, "opposite" means that the first surface 111 and the second surface 211 are parallel or nearly parallel. "Closely adjacent" means that the first surface 111 and the second surface 211 are nearly touching, with a very small or virtually no gap between them. Optionally, the gap between the first surface 111 and the second surface 211 is less than or equal to 1 mm. By providing a rotating part 113 on the first plate surface 111 and a mating part 220 on the second plate surface 211 that rotates and engages with the rotating part 113 around the first axis, the first wireless charging module 100 and the second wireless charging module 200 can rotate along the first plate surface 111 (second plate surface 211). In this way, the rotating part 113 and the mating part 220 can be hidden in any rotation state of the first wireless charging module 100 and the second wireless charging module 200, preventing them from being exposed. This avoids problems such as uneven rotation and jamming caused by hair, paper scraps and other debris getting tangled between the rotating part 113 and the mating part 220. On the other hand, it ensures the flatness and consistency of the entire wireless charging bracket, improving the aesthetics of the product.

[0076] The first housing 110 and the second housing 210 can be made of various materials, such as metal, plastic, and glass. Different materials can also be used in different parts of the first housing 110 and the second housing 210 as needed. No specific limitations are placed on the materials of the first housing 110 and the second housing 210 here. The shapes of the first housing 110 and the second housing 210 can also be varied. For example, the first housing 110 and the second housing 210 can be in the form of a plate. Of course, in some embodiments, the first housing 110 and the second housing 210 can also be set in a hemispherical or other shapes, as long as the first housing 110 has a first plate surface 111 and the second housing 210 has a second plate surface 211.

[0077] The first axis is perpendicular to the first plate surface 111 and the second plate surface 211, that is, the first axis is parallel or collinear with the normal directions of the first plate surface 111 and the second plate surface 211. The rotating part 113 and the mating part 220 can have various structural forms. For example, both the rotating part 113 and the mating part 220 can be cylindrical structures, or the rotating part 113 can be provided with an annular groove, and the mating part 220 can be provided with an annular protrusion 112 adapted to the annular groove, to achieve a rotatable connection between the two. The specific structure of the rotating part 113 and the mating part 220 is not limited here, as long as the rotating part 113 and the mating part 220 can be rotatably connected around the first axis. It should be noted that the rotating part 113 is fixedly connected to the first plate surface 111, and the mating part 220 is fixedly connected to the second plate surface 211. The rotating part 113 and the mating part 220 can be integrally formed with their corresponding housings or separately provided, depending on actual needs. The relative rotation angle between the first wireless charging module 100 and the second wireless charging module 200 can be designed according to actual needs. For example, the relative rotation angle between the two can be designed to be 360 ​​degrees, 180 degrees, 90 degrees, etc., without specific limitations here.

[0078] The power supply component 140 is specifically a rechargeable battery. It is first charged by an external power source, and then it provides power to the first wireless charging component 130 and the second wireless charging component 240. With a power source installed inside the first housing 110 or the second housing 210, the entire wireless charging stand forms a power bank module. That is, the wireless charging stand does not require an external power source; it can directly power the first wireless charging component 130 and the second wireless charging component 240 through the built-in power supply component 140, making it convenient for users to charge mobile phones, Bluetooth headsets, watches, and other electronic devices outdoors or in scenarios without external power.

[0079] The wireless charging bracket of this application has a power supply component 140 built into the first wireless charging module 100 or the second wireless charging module 200. When the wireless charging bracket is not connected to an external power source, it can directly supply power to the first wireless charging component 130 and the second wireless charging component 240 through the built-in power supply component 140, which makes it convenient for users to charge electronic devices such as mobile phones, Bluetooth headsets, and watches outdoors or in scenarios without external power. Furthermore, the first wireless charging module 100 of the wireless charging stand has a first plate surface 111 and a rotating part 113 disposed on the first plate surface 111, and the second wireless charging module 200 has a second plate surface 211 and a mating part 220 disposed on the second plate surface 211. The rotating part 113 is rotatably connected to the mating part 220 around the normal of the first plate surface 111, so that the second wireless charging module can rotate relative to the first wireless charging module along the first plate surface 111. In this way, the rotating part 113 and the mating part 220 can be hidden in any rotation state of the first wireless charging module 100 and the second wireless charging module 200, avoiding their exposure. On the one hand, this can avoid the phenomenon of uneven rotation and jamming caused by hair, paper scraps and other debris getting tangled between the rotating part 113 and the mating part 220. On the other hand, it can ensure the flatness and consistency of the appearance of the entire wireless charging stand, improving the aesthetics of the product.

[0080] In one embodiment, such as Figures 1 to 4 As shown, the first housing 110 and the second housing 210 are plate-shaped, and the first plate surface 111 and the second plate surface 211 have the same shape and area; the second wireless charging module 200 can be rotated relative to the first wireless charging module 100 to a stacked position, and in the stacked position, the outer peripheral walls of the first housing 110 and the second housing 210 are aligned.

[0081] In this embodiment, the first housing 110 and the second housing 210 are plate-shaped, that is, the first housing 110 and the second housing 210 are flat structures with two opposing plate surfaces. The outer contour shapes of the first housing 110 and the second housing 210 can be various, such as circular, elliptical, square, rectangular, etc. To ensure the battery capacity of the wireless charging holder, preferably, the outer contour shapes of the first housing 110 and the second housing 210 are rounded rectangles. This ensures that the shape and area of ​​the first plate surface 111 and the second plate surface 211 are the same, and that the outer peripheral walls of the first housing 110 and the second housing 210 are aligned when stacked. In this way, the entire wireless charging holder can be stacked into a large plate structure. When the user holds and stores it, the outer peripheral walls of the first wireless charging module 100 and the second wireless charging module 200 will not protrude and feel uncomfortable, thereby improving the user's handling experience. Meanwhile, since the outer peripheral walls of the first housing 110 and the second housing 210 can be aligned, the overall appearance of the wireless charging stand can be kept flat, resulting in a higher aesthetic appeal.

[0082] Furthermore, such as Figure 1 and Figure 2 As shown, the outer peripheral wall of the first housing 110 extends in a straight line along the plate thickness of the first housing 110, and the outer peripheral wall of the second housing 210 extends in a straight line along the plate thickness of the second housing 210.

[0083] In this embodiment, the outer peripheral walls of both the first housing 110 and the second housing 210 extend in a straight line along their thickness direction. This means that there is no arc transition between the outer peripheral wall of the first housing 110 and its two opposing plates, or between the outer peripheral wall of the second housing 210 and its two opposing plates, or an arc transition with a very small radius, such as a radius less than 0.5 mm. This allows the outer peripheral walls of the first housing 110 and the second housing 210 to be close together, minimizing the gap between them and preventing small debris from getting stuck. It also ensures the continuity and flatness of the appearance of the first housing 110 and the second housing 210, improving the overall feel and aesthetics of the wireless charging module.

[0084] In one embodiment, such as Figure 5 and Figure 6 As shown, the first wireless charging component 130 is disposed inside the first housing 110 on the side away from the first plate surface 111, and the second wireless charging component 240 is disposed inside the second housing 210 on the side close to the second plate surface 211. The second wireless charging component 240 and the mating part 220 are arranged diagonally in the extension direction of the second plate surface 211. The second wireless charging module 200 can be rotated to an unfolded position relative to the first wireless charging module 100. In the unfolded position, the part of the second housing 210 corresponding to the second wireless charging component 240 is exposed in the first housing 110.

[0085] In this embodiment, it is understood that since the rotating part 113 is provided on the first plate 111, the first wireless charging component 130 is disposed inside the first housing 110 on the side away from the first plate 111. This maximizes the size of the transmitting coil of the first wireless charging component 130 and allows the entire surface of the first housing 110 away from the first plate 111 to be used to place electronic devices. Thus, the first wireless charging module 100 can be used to wirelessly charge larger electronic devices (such as mobile phones, tablets, etc.). The second wireless charging component 240 is disposed on the side of the second housing 210 closer to the second plate 211. That is, both the first wireless charging component 130 and the second wireless charging component 240 are disposed on the same side of the first wireless charging module 100 and the second wireless charging module 200. In this way, the first wireless charging module 100 and the second wireless charging module 200 of the wireless charging bracket can charge two different electronic devices on the same side, thereby making it more convenient for users.

[0086] By arranging the second wireless charging component 240 and the mating part 220 diagonally along the extension direction of the second plate surface 211, when the wireless charging stand is unfolded, one end of the first wireless charging module 100 with the rotating part 113 and one end of the second wireless charging module 200 with the mating part 220 are located at the bottom, while the portion of the second wireless charging module 200 corresponding to the second wireless charging component 240 is located at the top. This makes it easier for users to place and retrieve the electronic devices corresponding to the second wireless charging module 200. If the user only needs to charge using the first wireless charging module 100, the first wireless charging module 100 and the second wireless charging module 200 can be rotated to the overlapping position. In this way, the entire wireless charging stand is equivalent to a block-shaped power bank, occupying little space and making it more convenient to carry and use. When the first wireless charging module 100 and the second wireless charging module 200 are rotated to the unfolded position, two electronic devices can be charged simultaneously using both wireless charging modules. Thus, the user can adjust the relative rotational positions of the first wireless charging module 100 and the second wireless charging module 200 according to usage needs, thereby improving the flexibility of product use.

[0087] Furthermore, such as Figure 11 , Figure 16 and Figure 18 As shown, the first wireless charging component 130 includes a first coil 131, and the second wireless charging component 240 includes a second coil 241. The diameter of the first coil 131 is larger than the diameter of the second coil 241, so that the wireless output power of the first wireless charging component 130 is greater than the wireless output power of the second wireless charging component 240.

[0088] In this embodiment, the diameter of the first coil 131 is larger than the diameter of the second coil 241, so that the wireless output power of the first wireless charging component 130 is greater than that of the second wireless charging component 240. Thus, the first wireless charging component 130 can charge higher-power electronic devices such as mobile phones, while the second wireless charging component 240 can charge lower-power electronic devices such as Bluetooth headsets and smartwatches, thereby meeting the simultaneous charging needs of different electronic devices. Furthermore, since the second wireless charging component 240 is located close to the second plate surface 211, placing the smaller-diameter second coil 241 within the second wireless charging module 200 and the larger-diameter first coil 131 within the first wireless charging module 100 makes efficient use of the available area of ​​the first plate surface 111 and the second plate surface 211, resulting in a more rational layout of the entire wireless charging bracket.

[0089] In one embodiment, please refer to Figure 5The second wireless charging module 200 can rotate and unfold 90 degrees relative to the first wireless charging module 100. When the second wireless charging module 200 rotates and unfolds 90 degrees relative to the first wireless charging module 100, the first side wall 119 of the first housing 110 is aligned with the second side wall 227 of the second housing 210.

[0090] In this embodiment, when the second wireless charging module 200 rotates 90 degrees relative to the first wireless charging module 100, the portion of the second housing 210 corresponding to the second wireless charging component 240 is exposed in the first housing 110. By aligning the first sidewall 119 of the first housing 110 with the second sidewall 227 of the second housing 210 when the first wireless charging module 100 and the second wireless charging module 200 are unfolded relative to each other by 90 degrees, the flatness of the two when unfolded by 90 degrees can be guaranteed, preventing the user from scratching their hands during use and resulting in a high degree of appearance flatness.

[0091] In one embodiment, such as Figures 5 to 8 As shown, the first wireless charging module 100 also includes a first magnetic element 150 disposed adjacent to the first wireless charging component 130; the second wireless charging module 200 also includes a support structure 260 and a second magnetic element 250 disposed adjacent to the second wireless charging component 240. The support structure 260 is connected to the surface of the second housing 210 away from the second plate surface 211, and is disposed at the middle of the first wireless charging module 100 in the extension direction of the first side wall 119. The end of the support structure 260 away from the second side wall 227 is rotatably connected to the second housing 210, and the end of the support structure 260 near the second side wall 227 can be unfolded relative to the second housing 210 at a preset angle to support the first wireless charging module 100 and the second wireless charging module 200 when the second wireless charging module 200 is rotated and unfolded 90 degrees relative to the first wireless charging module 100.

[0092] In this embodiment, when the first wireless charging module 100 is designed to charge a mobile phone, the first magnetic element 150 is arranged around the transmitting coil of the first wireless charging assembly 130 to magnetically attract with the magnetic ring inside the mobile phone. When the second wireless charging module 200 is designed to charge an electronic watch or Bluetooth headset, the second magnetic element 250 is a magnetic block disposed in the transmitting coil of the second wireless charging assembly 240 to magnetically attract with the magnetic block inside the electronic watch or Bluetooth headset.

[0093] The support structure 260 can have various structures and forms, such as a support ring or a support plate. To improve ease of use, the support structure 260 is designed to unfold to a preset angle relative to the second housing 210 and be stored within the second housing 210. This preset angle can be designed according to actual needs; for example, the preset angle can be 30 to 50 degrees, so that the first wireless charging module 100 and the second wireless charging module 200 are not too flat or too upright. Optionally, the support structure 260 includes a support member 261, a fixing member 262, and a hinge member 263. The fixing member 262 is fixedly connected to the second housing 210, and one end of the support member 261 is rotatably connected to the fixing member 262 through the hinge member 263, so that the other end of the support member 261 can unfold to a preset angle relative to the second housing 210 or be stored within the second housing 210. Therefore, when support is needed, the support member 261 can be unfolded to support the entire wireless charging stand. When support is not needed, the support member 261 can be retracted to ensure the flatness of the entire wireless charging stand.

[0094] By positioning the support structure 260 at the center of the first wireless charging module 100 along the extension direction of the first sidewall 119, and allowing the end of the support structure 260 near the second sidewall 227 to unfold at a predetermined angle relative to the second housing 210, the support structure 260 can reliably support the center of the first wireless charging module 100, thereby improving the stability of the entire wireless charging stand. Simultaneously, when the support structure 260 is unfolded and supports the wireless charging stand, the first sidewall 119 of the first wireless charging module 100 and the second sidewall 227 of the second wireless charging module 200 are located at the bottom of the entire wireless charging stand and are flush, improving the visual appeal and thus enhancing the user experience.

[0095] In one embodiment, such as Figures 7 to 10 The rotating part 113 is upper limit connected to the mating part 220 in the extension direction of the first axis, so that the first wireless charging module 100 and the second wireless charging module 200 cannot be separated during rotation. A limiting fit structure can be provided on the rotating part 113 and the mating part 220 to prevent the first wireless charging module 100 and the second wireless charging module 200 from separating from each other in the extension direction of the rotation axis. This effectively prevents the first wireless charging module 100 and the second wireless charging module 200 from separating from each other during rotation, improving overall reliability.

[0096] Furthermore, such as Figures 7 to 10 , Figures 12 to 17As shown, the rotating part 113 includes a rotating cylinder 114 and a limiting disk 115. The rotating cylinder 114 is fixedly installed on the first housing 110 and at least partially protrudes from the first plate surface 111. The limiting disk 115 is detachably connected to one end of the rotating cylinder 114 facing the second plate surface 211. At least part of the outer peripheral wall of the limiting disk 115 is located outside the outer peripheral wall of the rotating cylinder 114. The second plate surface 211 has a rotating through hole 212 corresponding to the rotating part 113. The mating part 220 includes an embedded protruding ring 221 arranged around the inner peripheral edge of the rotating through hole 212. The embedded protruding ring 221 is adapted to be fitted on the outer periphery of the rotating cylinder 114, and the embedded protruding ring 221 is rotatably disposed between the limiting disk 115 and the first plate surface 111 around the first axis.

[0097] In this embodiment, the rotating cylinder 114 and the first housing 110 can be integrally formed or be detachable components. It is understood that the rotating cylinder 114 is specifically cylindrical, meaning its cross-section is circular. The limiting disc 115 and the rotating cylinder 114 can be detachably and fixedly connected by screws, clips, or other means. This detachable and fixed connection between the limiting disc 115 and the rotating cylinder 114 facilitates the assembly of the embedded protruding ring 221 within the limiting disc 115 and the first plate surface 111. At least a portion of the outer peripheral wall of the limiting disc 115 is located outside the outer peripheral wall of the rotating cylinder 114. A limiting space is formed between the portion of the limiting disc 115 protruding from the outer peripheral wall of the rotating cylinder 114 and the first plate surface 111. Therefore, the fitting protrusion 221 of the mating part 220 is disposed between the limiting disc 115 and the first plate surface 111, that is, within this limiting space. The portion of the limiting disc 115 protruding from the outer peripheral wall of the rotating cylinder 114 and the first plate surface 111 restricts the movement of the fitting protrusion 221 in the extension direction along the first axis, thereby effectively preventing the first wireless charging module 100 and the second wireless charging module 200 from separating during rotation. In practice, the limiting disc 115 is installed inside the second housing 210 to clamp the fitting protrusion 221 of the second housing 210 together with the first plate surface 111. In this embodiment, by opening a rotating through hole 212 on the second plate surface 211, the rotating cylinder 114 is rotatably installed in the rotating through hole 212. The embedded protruding ring 221 at the inner periphery of the rotating through hole 212 is restricted by the limiting plate 115 and the first plate surface 111. At the same time, the rotating part 113 and the mating part 220 integrate the rotating structure and the axial limiting structure, thereby simplifying the rotating and axial limiting structure of the first wireless charging module 100 and the second wireless charging module 200 and reducing manufacturing costs.

[0098] Furthermore, such as Figure 7 , Figure 8 , Figure 12 , Figure 13As shown, the rotating part 113 also includes a mounting plate 116. The mounting plate 116 is fixedly connected to one end of the rotating cylinder 114 away from the second plate surface 211. The outer periphery of the mounting plate 116 protrudes from the outer peripheral wall of the rotating cylinder 114. The mounting plate 116 is circumferentially limited and embedded in the inner wall surface of the first housing 110. The rotating cylinder 114 passes through the first plate surface 111 and is embedded in the rotating through hole 212.

[0099] In this embodiment, the mounting plate 116 and the rotating cylinder 114 can be integrally formed or separately formed. The mounting plate 116 and the first housing 110 can be circumferentially limited by structures such as protrusions and grooves. Of course, protrusions or grooves can also be provided on the outer peripheral wall of the rotating cylinder 114 to cooperate with the grooves and protrusions on the embedded flange to realize the circumferential rotation of the rotating cylinder 114 relative to the first housing 110. By providing the mounting plate 116, the circumferential and axial limiting of the rotating cylinder 114 relative to the first housing 110 can be realized, ensuring the fixed reliability of the rotating cylinder 114 and the first housing 110.

[0100] Furthermore, such as Figure 10 and Figure 12 As shown, the first wireless charging module 100 also includes a frame 160, which surrounds and fits the inner peripheral wall of the first housing 110. The frame 160, the rotating cylinder 114 and the mounting plate 116 are integrally formed.

[0101] In this embodiment, by setting a frame 160 to surround and fit the inner peripheral wall of the first housing 110, the peripheral wall of the first housing 110 can be structurally strengthened, thereby improving the structural strength of the entire outer periphery of the first wireless charging module 100. Furthermore, by integrally molding the frame 160, the rotating cylinder 114, and the mounting plate 116, the installation reliability of the rotating cylinder 114 and the mounting plate 116 relative to the first housing 110 is ensured, while the ease of installation of the internal structure is improved, thus increasing installation efficiency. Optionally, the first housing 110 is made of metal, and the frame 160 is made of insulating material. For example, the frame 160 can be made of insulating materials such as plastic or carbon fiber. In this way, the frame 160 can also serve an insulating function, thereby improving the reliability of the product.

[0102] Furthermore, such as Figures 10 to 12 As shown, the frame 160 and the mounting plate 116 are connected by a connecting plate 170. The power supply component 140 is installed inside the frame 160. The power supply component 140 is electrically connected to the second wireless charging component 240 through a wire. The wire passes through the middle of the rotating cylinder 114 and the rotating through hole 212. The first wireless charging module 100 also includes a wire pressing plate 180, which is pressed onto the wire and fixedly connected to the connecting plate 170.

[0103] In this embodiment, the connecting wires of the power supply component 140 and the second wireless charging component 240 pass through the middle of the rotating cylinder 114 and the rotating through hole 212, which can prevent the wires of the first wireless charging module 100 and the second wireless charging module 200 from being damaged by winding when they rotate relative to each other. The pressure plate 180 and the connecting plate 170 can be fixedly connected by screws. The frame 160 and the rotating cylinder 114 are connected by the connecting plate 170, which can ensure the reliability of the connection between the frame 160 and the mounting plate 116. The pressure plate 180 is fixed on the connecting plate 170, which avoids damage to the outer surface of the first housing 110 compared to fixing the pressure plate 180 to the first housing 110, thus ensuring the integrity and consistency of the outer surface of the first housing 110. By pressing the pressure plate 180 onto the connecting wires of the power supply component 140 and the second wireless charging component 240, the wires are effectively prevented from lifting and breaking when the first wireless charging module 100 and the second wireless charging module 200 rotate relative to each other.

[0104] In one embodiment, please refer to Figures 7 to 10 , Figure 14 and Figure 15 The wall of the first plate surface 111 protrudes outward around the rotating part 113 to form an annular protrusion 112, and the wall of the second plate surface 211 is recessed in response to the annular protrusion 112 to form an embedded groove 213. The mating part 220 is disposed in the embedded groove 213. A damping ring 190 is sleeved around the annular protrusion 112, and the damping ring 190 is sandwiched between the first plate surface 111 and the second plate surface 211.

[0105] The engagement of the annular protrusion 112 and the recessed groove 213 provides initial positioning of the first plate surface 111 and the second plate surface 211 along their extension direction, preventing the first wireless charging module 100 and the second wireless charging module 200 from deviating from their rotation axis during rotation. By sleeved with a damping ring 190 around the annular protrusion 112, the damping ring 190 is positioned between the first plate surface 111 and the second plate surface 211. This prevents the first plate surface 111 and the second plate surface 211 from coming into contact and generating rotational friction noise, while also providing rotational resistance to prevent excessively smooth rotation. The damping ring 190 can be made of materials with a high coefficient of friction, such as rubber or silicone.

[0106] In one embodiment, such as Figure 9 , Figures 12 to 19 The outer peripheral wall of the rotating part 113 is provided with a plurality of positioning slots 117 that are sequentially adjacent to each other around the first axis; the mating part 220 is provided with a positioning protrusion 222 corresponding to the positioning slot 117, the end of the positioning protrusion 222 is adapted to engage in one of the positioning slots 117, and the end of the positioning protrusion 222 can rotate and switch between two adjacent positioning slots 117.

[0107] In this embodiment, the number of positioning slots 117 can be selected and designed according to actual needs, and is not specifically limited here. Positioning slots 117 and positioning protrusions 222 are provided on the rotating part 113 and the mating part 220. When the first wireless charging module 100 rotates relative to the second wireless charging module 200, the positioning protrusions 222 and the positioning slots 117 cooperate to achieve initial locking and positioning. On the one hand, this prevents the first wireless charging module 100 from rotating further relative to the second wireless charging module 200 under the action of inertial force, allowing the user to precisely adjust the rotation angle of the first wireless charging module 100. On the other hand, when the positioning protrusions 222 switch between adjacent positioning slots 117 under the action of external force, a mechanical switching sound is emitted, which can enhance the fun of rotating the first wireless charging module 100 and the second wireless charging module 200, improve the user's feel, and thus enhance the user experience.

[0108] Further, please refer to Figure 18 and Figure 19 The second wireless charging module 200 also includes a spring 226. The positioning card protrusion 222 has a corresponding protrusion 223 and a guide post 224. The protrusion 223 is adapted to engage in one of the positioning card slots 117. The spring 226 is sleeved around the guide post 224 and sandwiched between the positioning card protrusion 222 and the second housing 210.

[0109] The spring 226 is specifically a compression spring 226. The function of the compression spring 226 is to apply continuous pressure to the positioning protrusion 222, ensuring that the positioning protrusion 222 tightly fits the positioning slot 117 at any rotation angle, maintaining a stable connection between the modules. When the user adjusts the angle, the spring 226 can be compressed, allowing the positioning protrusion 222 to smoothly switch from one positioning slot 117 to an adjacent one. The spring force of the spring 226 will automatically recover when the user releases it, pushing the positioning protrusion 222 back to the nearest positioning slot 117, ensuring that the wireless charging module can be stably locked in the preset position after rotation, thus guaranteeing both flexibility of use and enhanced durability of the module.

[0110] In one embodiment, such as Figure 12 , Figure 13 , Figures 17 to 19 As shown, the outer peripheral wall of the rotating part 113 is also provided with a limiting groove 118 extending along its circumference, and the mating part 220 is provided with a limiting plug 225. The limiting plug 225 can be slidably inserted into the limiting groove 118 around the first axis to limit the rotation angle of the second wireless charging module 200 relative to the first wireless charging module 100.

[0111] In this embodiment, the limiting groove 118 is specifically arranged in an arc shape. The extension length of the limiting groove 118 can be designed according to the required rotation angle. When the limiting block 225 moves to abut against the side wall of the limiting groove 118 in the circumferential direction of the rotating part 113, it can stop the rotation of the first wireless charging module 100 and the second wireless charging module 200, so as to reliably control the rotation range of the first wireless charging module relative to the second wireless charging module 200.

[0112] In one embodiment, such as Figure 10 , Figure 15 and Figure 16 As shown, the first housing 110 and the second housing 210 are plate-shaped. The first housing 110 includes a first main housing 120 and a first panel 122. The first panel 111 is disposed on the first main housing 120. The first main housing 120 has a first opening 121 on the side away from the first panel 111. The first panel 122 is adapted to cover the first opening 121. The second housing 210 includes a second main housing 230 and a second panel 232. The second panel 211 is disposed on the second main housing 230. The second main housing 230 has a second opening 231 on the side away from the second panel 211. The second panel 232 is adapted to cover the second opening 231. The first panel 122 and the second panel 232 are made of glass.

[0113] The first housing 110 and the second housing 210 are plate-shaped, making it easier for users to hold the wireless charging stand. Furthermore, when using the wireless charging stand, the user's hand will come into contact with a large area of ​​the first panel 122 and the second panel 232. By making the first panel 122 and the second panel 232 of glass, the user's tactile comfort and visual aesthetics can be significantly improved. The first panel 122 and the first main housing 120, and the second panel 232 and the second main housing 230, can be fixedly connected by adhesive.

[0114] Furthermore, such as Figure 5 , Figures 14 to 17 As shown, both the first main shell 120 and the second main shell 230 are made of metal material, and the first wireless charging component 130 is located inside the first main shell 120 near the first panel 122.

[0115] The second plate 211 has a through hole 214. The second wireless charging module 200 also includes an insulating inner shell 280 installed in the second main shell 230. The insulating inner shell 280 has a device placement part 281 adapted to be embedded in the through hole 214. The second wireless charging component 240 is installed in the insulating inner shell 280 at the position corresponding to the device placement part 281.

[0116] The second wireless charging module 200 can be rotated to an unfolded position relative to the first wireless charging module 100. In the unfolded position, the device placement part 281 is exposed in the first housing 110.

[0117] In this embodiment, the first main shell 120 and the second main shell 230 are made of metal. This improves the product's feel and appearance, while also enhancing its structural strength and drop resistance. An insulating inner shell 280 is provided inside the second main shell 230, with a device placement portion 281 exposed on the second panel 211. The second wireless charging assembly 240 is mounted on the insulating inner shell 280 at the position corresponding to the device placement portion 281. This prevents the metal main shell from blocking the wireless signal of the second wireless charging assembly 240, thus ensuring the efficiency of wireless charging.

[0118] In one embodiment, the first wireless charging component 130 includes a first coil 131, and the second wireless charging component 240 includes a second coil 241 and a control board 242. The diameter of the first coil 131 is larger than the diameter of the second coil 241, so that the wireless output power of the first wireless charging component 130 is greater than the wireless output power of the second wireless charging component 240.

[0119] The power supply unit 140 is located inside the first housing 110. The second wireless charging module 200 also includes a charging interface 290, which is electrically connected to the control board 242. After the charging interface 290 is connected to an external power source, the control board 242 is used to first supply power to the external device when it detects a charging signal from an external device placed on the first wireless charging module 100 and the second wireless charging module 200, and then supply power to the power supply unit 140 when it detects that the external device is fully charged or not connected to the external device.

[0120] In this embodiment, the wireless output power of the first wireless charging component 130 is greater than that of the second wireless charging component 240. Thus, the first wireless charging component 130 can charge higher-power electronic devices such as mobile phones, while the second wireless charging component 240 can charge lower-power electronic devices such as Bluetooth headsets and smartwatches, thereby meeting the simultaneous charging needs of different electronic devices.

[0121] When an external power source is connected to the charging port 290, the built-in power supply unit 140 of the wireless charging stand can be charged. When an external device is connected to the charging port 290, the built-in power supply unit 140 can provide wired power to the external device. By designing the control circuit on the control board 242, after the charging port 290 is connected to an external power source, and the control board 242 detects a charging signal from an external device placed on the first wireless charging module 100 and the second wireless charging module 200, it first supplies power to the external device. Only when the external device is detected to be fully charged or not connected does it supply power to the power supply unit 140. Thus, the wireless charging stand prioritizes charging external devices (mobile phones, Bluetooth headsets, smartwatches, etc.) after connecting to an external power source, and only begins charging the power supply unit 140 after the external device is fully charged. This design optimizes the charging sequence, allowing users to quickly charge the devices they need when using the wireless charging stand, greatly improving ease of use.

[0122] In one embodiment, such as Figure 5 , Figures 14 to 18 , Figure 20 and Figure 21 As shown, the second panel 211 has a light-transmitting hole 215 near the second wireless charging assembly 240. The second wireless charging module 200 also includes a light guide 291 and a decorative piece 296. The light guide 291 includes a light guide ring 292 and a light guide tube 294 connected to each other. The light guide tube 294 is installed in the light-transmitting hole 215 and forms an inward-facing lamp bead receiving groove 295. The light guide ring 292 is exposed in the light-transmitting hole 215 and forms an mounting groove 293. The decorative piece 296 is installed in the mounting groove 293.

[0123] The second wireless charging module 200 can be rotated to an unfolded position relative to the first wireless charging module 100. In the unfolded position, the part of the second housing 210 corresponding to the second wireless charging component 240 and the light guide ring 292 are exposed to the first housing 110.

[0124] In this embodiment, the control board 242 is equipped with LED beads, which are housed in the LED bead receiving slot 295 to provide a light source for the light guide 291. The LED beads can emit different colors of light, adjusting the color according to changes in the charging status, thereby intuitively displaying the charging status of the device to the user. The light guide 291 can be made of transparent or semi-transparent light guide material, which can transmit light evenly. By setting the light guide ring 292, when the second wireless charging module 200 is unfolded, the light guide ring 292 can form a soft and uniform light ring, which can be used to indicate the charging status of external devices, combining functionality and product aesthetics. In practice, the outer surface of the decorative piece 296 is flush with the outer surface of the second panel 211. The decorative piece 296 can be made of the same color as the second panel 211 or a material with a specific pattern, enhancing the overall aesthetics of the product.
