[0035] This embodiment relates to a two-in-one wireless charging device. Referring to Figures 1-4 , it includes a main housing 100, a mobile phone wireless charging module 200, and a watch wireless charging module 300. Among them, a control circuit board is built into the main housing 100. Specifically, a charging interface 121 communicating with the outside of the main housing 100 is provided on the control circuit board to provide power for this wireless charging device. The mobile phone wireless charging module 200 is rotatably connected to the main housing 100. The mobile phone wireless charging module 200 can rotate relative to the main housing 100, and the user can adjust the angle as needed. It is also convenient to play with the mobile phone or watch movies while charging. If the angle adjustment is no longer needed, the mobile phone wireless charging module 200 can be closed on the main housing 100, and it is in a horizontal state at this time. Specifically, a magnetic member (not shown) is also provided in the mobile phone wireless charging module 200. The magnetic member can enhance the charging stability between the mobile phone device and the mobile phone wireless charging module 200. Especially when the mobile phone wireless charging module 200 is at an inclined angle, the magnetic member can prevent the mobile phone device from slipping off the mobile phone wireless charging module 200. The watch wireless charging module 300 is detachably assembled on the main housing 100, and the user can easily remove or install the watch wireless charging module 300 from the charging device, which is convenient for carrying and using.

Through the built-in first wireless charging coil and second wireless charging coil 310, the mobile phone wireless charging module 200 and the watch wireless charging module 300 can perform wireless charging simultaneously without using an additional charger, improving the charging efficiency. Further, an output interface 110 for docking the watch wireless charging module 300 is provided on the main housing 100, and an input interface 320 corresponding to the output interface 110 is provided on the watch wireless charging module 300. When the input interface 320 is docked with the output interface 110, the watch wireless charging module 300 is assembled onto the main housing 100, and the second wireless charging coil 310 of the watch wireless charging module 300 is electrically connected to the control circuit board of the main housing 100, and the charging process can start without additional plugging steps, realizing plug and play. When the watch wireless charging module 300 is not in use, the input interface 320 is pulled out of the output interface 110, and the watch wireless charging module 300 is disconnected and powered off from the main housing 100. At this time, the watch wireless charging module 300 is detachably assembled on the main housing 100, and the user can pull down the watch wireless charging module 300 when not in use, which is convenient for carrying and storing. Therefore, this wireless charging device has the advantages of being detachable and convenient for carrying.

[0036] In this embodiment, referring to Figure 4, the control circuit board includes: a main control circuit board 120 disposed at the inner bottom of the main housing 100 and a watch wireless charging circuit board 130 disposed near the upper part inside the main housing 100, electrically connected to the main control circuit board 120 and used for electrically connecting to the output interface 110. The control circuit board is divided into two parts. The watch wireless charging circuit board 130 is specifically responsible for the charging control of the watch wireless charging module 300, which can be optimized according to the charging characteristics of the watch, improve the charging efficiency, and at the same time reduce unnecessary energy consumption. At the same time, the heat generated during the charging process is a common problem of electronic products, especially during high-power charging. By setting the control circuit board at different positions and separately from the wireless charging coil, the heat sources are prevented from concentrating in one area. Therefore, the heat generated during the charging of the mobile phone wireless charging module 200 and the watch wireless charging module 300 is dispersed, enabling the wireless charging device to cool down quickly, helping to protect the device from overheating damage, maintaining temperature balance, and maintaining its good charging performance.

[0037] In this embodiment, referring to Figure 4 , the main housing 100 includes: a main body middle frame 180, an inner middle frame bracket 140 assembled inside the main body middle frame 180, and a bottom cover 150 disposed at the bottom of the main body middle frame 180. The inner middle frame bracket 140 and the bottom cover 150 together constitute the basic structure of the main housing 100. There are support columns 160 connected between the inner middle frame bracket 140 and the bottom cover 150. Fixing columns 141 extend from the lower side of the inner middle frame bracket 140 or the upper side of the bottom cover 150. The main control circuit board 120 is assembled on the fixing columns 141 so that the main control circuit board 120 has a heat dissipation space with both the inner middle frame bracket 140 and the bottom cover 150. The support columns 160, as the key components connecting the inner middle frame bracket 140 and the bottom cover 150, can play a strengthening role and also make the gap formed between the inner middle frame bracket 140 and the bottom cover 150 can be used as a heat dissipation channel for internal heat energy, which helps to improve the heat dissipation performance of the main control circuit board 120 and the entire device. At the same time, the fixing columns 141 are used to suspend the main control circuit board 120, further improving the heat dissipation performance.

[0038] In this embodiment, referring to Figures 4-5, the main housing 100 further includes: an upper cover 170 that is snap-connected to the main body middle frame 180, and the mobile phone wireless charging module 200 is rotatably connected to the top end of the upper cover 170; this connection method makes the assembly fast and simple, and has high stability. At the same time, the mobile phone wireless charging module 200 provided at the top end of the upper cover 170 is far away from the main control circuit board 120, and the heat generated when the mobile phone wireless charging module 200 is charging can be dispersed, so that the local temperature will not be too high, affecting the charging performance of the wireless charging device. Further, a recessed receiving groove 181 is provided on the main body middle frame 180, and the upper cover 170 is closed on the receiving groove 181. The watch wireless charging circuit board 130 and the output interface 110 are both provided in the receiving groove 181. The provision of the receiving groove 181 provides a space for accommodating the watch wireless charging circuit board 130 and the output interface 110, enhances the flatness and aesthetics of the overall device, and also saves space. Specifically, the middle frame inner bracket 140 is provided in the main body middle frame 180, the bottom of the main body middle frame 180 is attached to the bottom cover 150, and the upper cover 170 is closed on the main body middle frame 180, thereby forming a complete main housing 100, improving the overall structural strength and stability of the charging device, and also optimizing the internal structure.

[0039] In this embodiment, referring to Figures 4-6, the output interface 110 includes: an output port 111, a mounting groove 112 and a recessed portion 1121. The output port 111 is arranged in the receiving groove 181 and connected to the outside of the upper cover, and the output port 111 is electrically connected to the watch wireless charging circuit board 130. The mounting groove is arranged on the upper cover 170 and is provided for docking with the watch wireless charging module 300. The arrangement of the mounting groove 112 enables the watch wireless charging module 300 to fit completely when the watch wireless charging module 300 is inserted into the main housing 100, ensuring that the watch wireless charging module 300 can be accurately aligned with the output port 111 every time, thereby enhancing the stability of the connection. The recessed portion 1121 is arranged on the peripheral side of the mounting groove 112. The input interface 320 includes: an input port 321 corresponding to the output port 111 and a protruding portion 322 corresponding to the recessed portion 1121. The recessed portion 1121 and the protruding portion 322 cooperate with each other, so that the watch wireless charging module 300 can be firmly connected when it is connected to the main housing 100. Furthermore, when the watch wireless charging module 300 is connected to the main housing 100, the output port 111 is connected to the input port 321, and both are electrically connected to the watch wireless charging circuit board 130, and the protrusion 322 is placed in the recess 1121. Therefore, when the watch wireless charging module 300 is connected to the main housing 100, the protrusion 322 is placed in the recess 1121, and the precise docking of the output interface 110 and the input interface 320 ensures that the watch wireless charging module 300 can be firmly fixed in place when connected to the main housing 100. The setting of the protrusion 322 and the recess 1121 ensures that the watch wireless charging module 300 can be accurately positioned when inserted into the installation slot 112, forming a stable connection, and preventing the watch wireless charging module 300 from shaking or falling off during the charging process.

[0040] Specifically in this embodiment, the charging interface 121, the output interface 110 and the input interface 320 all use TYPE-C interfaces. In other embodiments, the charging interface 121, the output interface 110 and the input interface 320 may also use USB interfaces or other power interfaces.

[0041] In this embodiment, a pull ring 330 is provided at one end of the watch wireless charging module 300 away from the input interface 320. The pull ring 330 allows the user to easily insert and remove the watch wireless charging module 300 relative to the main housing 100, especially when the watch wireless charging module 300 is tightly embedded in the installation groove 112, the pull ring 330 provides a fulcrum, making the removal process more convenient.

[0042] In this embodiment, refer to Figures 7-9, the main housing 100 and the mobile phone wireless charging module 200 are connected by a shaft assembly 400. The shaft assembly 400 allows the mobile phone wireless charging module 200 to adjust its angle relative to the main housing 100, and the user can adjust the angle of the mobile phone wireless charging module 200 as needed. Furthermore, a rotating hole 190 for the rotating shaft assembly 400 to rotate is provided on the main housing 100, one end of the rotating shaft assembly 400 is fixedly connected to the bottom of the mobile phone wireless charging module 200, and the other end is placed in the rotating hole 190 and fixedly connected to the main housing 100. Through the shaft assembly 400, the connection between the mobile phone wireless charging module 200 and the main housing 100 is very stable, and can remain stable even after adjusting the angle, and will not loosen or move easily. At the same time, the mobile phone wireless charging module 200 can be folded and opened relative to the main housing 100 through the shaft assembly 400. When in the open state, it can provide a better heat dissipation environment for the mobile phone wireless charging module 200, especially when charging, which helps to disperse heat energy and reduce overheating. Furthermore, a clearance groove 210 is provided at the bottom of the mobile phone wireless charging module 200, and when the shaft assembly 400 rotates, the clearance groove 210 avoids the main housing 100. The clearance groove 210 is to ensure that there is enough clearance between the mobile phone wireless charging module 200 and the main housing 100 when the shaft assembly 400 rotates to avoid collision or friction between the two, and also plays a limiting role, limiting the opening angle of the mobile phone wireless charging module 200.

[0043] In this embodiment, refer to Figure 8 , the shaft assembly 400 includes: a mounting plate 410, a shaft 420 and a shaft bracket 430. The mounting plate 410 is fixedly assembled in the main housing 100, providing a solid support point for the shaft 420, ensuring that the shaft assembly 400 remains stable during use. The shaft 420 is rotatably assembled on the mounting plate 410, which improves the rotation conditions for the shaft bracket 430. One end of the shaft bracket 430 is fixedly connected to the bottom of the mobile phone wireless charging module 200, and the other end is fixedly connected to the shaft 420. The shaft bracket 430 is used to drive the mobile phone wireless charging module 200 to rotate. The rotation of the shaft 420 drives the shaft bracket 430, and drives the mobile phone wireless charging module 200 to rotate to any point within the set angle. Through the rotation of the shaft 420, the angle of the shaft bracket 430 and the mobile phone wireless charging module 200 connected thereto can be adjusted. The user can adjust the mobile phone wireless charging module 200 to any set angle as needed, which improves the flexibility of use.

[0044] In this embodiment, the rotating shaft bracket 430 is provided with a through hole 431 communicating with the mobile phone wireless charging module 200, and a connecting wire is arranged in the through hole 431. The connecting wire is electrically connected to the main control circuit board 120 and is connected to the mobile phone wireless charging module 200 through the through hole 431. The rotating shaft assembly 400 further includes: a mounting bracket 440 fixedly assembled in the main housing 100 and on the side away from the mounting plate 410, and a connecting shaft provided on the mounting bracket 440 and having a hollow structure. The connecting shaft 450 is rotatably connected to the rotating shaft bracket 430, and the connecting wire passes through the connecting shaft. By passing the connecting wire through the hollow structures inside the rotating shaft bracket 430 and the connecting shaft, even when the mobile phone wireless charging module 200 rotates, the electrical connection between the mobile phone wireless charging module 200 and the main housing 100 can be ensured to be stable and reliable. At the same time, the connecting wire is hidden inside the rotating shaft bracket 430 and the connecting shaft, making the whole more concise and beautiful.

[0045] In this embodiment, referring to Figure 9 , a counterweight 142 is provided at the bottom of the inner bracket 140 of the middle frame. By providing the counterweight 142 at the bottom of the inner bracket 140 of the middle frame, the weight distribution of the entire device can be balanced, ensuring that the device will not tilt or become unstable due to uneven weight distribution even when the mobile phone wireless charging module 200 or the watch wireless charging module 300 is charging. Further, an anti-slip block 151 is provided at the bottom of the bottom cover 150, which can increase the friction between the bottom cover 150 and the placement surface and prevent the wireless charging device from sliding on a smooth tabletop or an inclined surface. Specifically, in this embodiment, the anti-slip block 151 is made of rubber material. In other embodiments, the anti-slip block 151 can also be made of other materials with a high coefficient of friction.

[0046] The working principle of the present utility model is generally as follows: When using the present utility model, the wireless charging device is powered on by connecting it to a power source through the charging interface 121. When the input interface 320 is docked with the output interface 110, the watch wireless charging module 300 is assembled onto the main housing 100, and the second wireless charging coil 310 of the watch wireless charging module 300 is electrically connected to the control circuit board of the main housing 100. Then the watch wireless charging module 300 can be connected and powered on. Both the first wireless charging coil and the second wireless charging coil 310 are electrically connected to the control circuit board. At this time, placing the watch device on the watch wireless charging module 300 enables wireless charging, and placing the mobile phone device on the mobile phone wireless charging module 200 also enables wireless charging. Thus, when it is necessary to adjust the angle of the mobile phone device, the mobile phone wireless charging module 200 only needs to rotate away from the upper surface of the main housing 100 through the rotating shaft assembly 400. At this time, the inclined angle of the mobile phone wireless charging module 200 is convenient for users to use. Moreover, since there is a magnetic attracting member provided in the mobile phone wireless charging module 200, even if the mobile phone wireless charging module 200 is inclined, the mobile phone device firmly adheres and does not affect wireless charging. However, when the wireless charging device is not in use, the input interface 320 is pulled out from the output interface 110, and the watch wireless charging module 300 is disconnected and powered off from the main housing 100, realizing that the watch wireless charging module 300 can be detachably assembled on the main housing 100. The user can pull down the watch wireless charging module 300, and at the same time, the mobile phone wireless charging module 200 rotates and closes on the main housing 100, which is convenient for carrying and storage. This wireless charging device has the advantages of being detachable and easy to carry.

[0047] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model, as long as they do not depart from the spirit and scope of the technical solution of the present utility model, shall be covered by the scope of the claims of the present utility model.
