Such a design forms a series power transmission path, so that all wireless charging modules in the entire charging device can share the same power input, and there is no need to equip each wireless charging module with a separate power supply.

[0018] 2. The charging device of the embodiment of the utility model realizes the rotational connection and electrical connection between the wireless charging modules at the same time through the connection structure, completes the dual functions through the unified connection structure, simplifies the internal structure of the device, and reduces the number of parts.

[0021] 5. The charging device according to the embodiment of the present utility model integrates the telescopic wire assembly as the power input end of the entire charging device, facilitating the user to adjust the length of the telescopic wire in different usage scenarios, and further improving the flexibility of use.

By rotating the second wireless charging component to adjust the charging position, it can effectively prevent interference between the watch strap and other positions of the charging device during charging; the specially provided storage hole on the second support provides a fixed storage position for the second wireless charging component, which not only facilitates the storage of the component, avoids loss or damage when not in use, but also maintains the neat appearance of the overall device and improves the integrity of the product design.

[0025] 9. In the charging device according to the embodiment of the present utility model, by presetting an installation groove and an installation step on the second housing assembly, a standardized installation position and method are provided for the third wireless charging component, ensuring that the wireless charging component can be quickly and accurately installed in place; at least part of the third wireless charging component is located in the installation groove. Such a design helps to reduce the protrusion of the external contour and is beneficial to improving space utilization.

[0026] 10. In the charging device according to the embodiment of the present utility model, the heat dissipation performance of the charging device can be effectively improved by providing heat dissipation fins and / or heat dissipation holes. Specifically, the provision of heat dissipation fins increases the surface area of the housing surface.

Such a design not only expands the application scenarios of the charging device through rotation adjustment, but also improves the utilization of space by rotating and folding the three wireless charging modules when not in use. Specifically, the types of the first wireless charging module, the second wireless charging module and the third wireless charging module can be the same or different, that is, the three wireless charging modules can increase the charging position of the charging device, and can charge a variety of electronic devices; the third wireless charging module is rotatably arranged on the second wireless charging module, so that the user can rotate the third wireless charging module alone to adjust the working range of the third wireless charging module or fold and store it; the second wireless charging module is rotatably arranged on the first wireless charging module, so that the user can rotate the second wireless charging module alone to adjust the working range of the second wireless charging module or fold and store it. At the same time, since the third wireless charging module is arranged on the second wireless charging module, the orientation of the third wireless charging module can also be adjusted by rotating the second wireless charging module, and the orientation of the third wireless charging module can also be adjusted by rotating the second wireless charging module and the second wireless charging module and the third wireless charging module at the same time, which has strong flexibility; the third wireless charging module is electrically connected to the second wireless charging module, and the second wireless charging module is electrically connected to the first wireless charging module. Such a design forms a series power transmission path, so that all wireless charging modules in the entire charging device can share the same power input, and there is no need to equip each wireless charging module with a separate power supply.

[0092] 2. The charging device of the embodiment of the utility model realizes the rotational connection and electrical connection between the wireless charging modules at the same time through the connection structure, completes the dual functions through the unified connection structure, simplifies the internal structure of the device, and reduces the number of parts.

At the same time, the cables can be arranged in an orderly manner inside the connection structure to avoid cable entanglement and damage, thereby simplifying the complexity of the assembly process and subsequent maintenance.

[0093] 3. The charging device of the embodiment of the utility model ensures smooth transition of the lines in different directions through the design of the first wiring hole and the second wiring hole, refines the line layout, makes the internal structure more reasonable, simplifies the assembly process, and also facilitates the inspection and replacement of cables.

[0094] 4. In the charging device according to the embodiment of the present utility model, the rotating groove is arranged on the watch wireless charging module. The watch wireless charging module requires a smaller charging area. Since the rotating groove needs to avoid the connection structure, it needs to occupy more space than the fixed groove. Therefore, setting the rotating groove on the watch wireless charging module has better space utilization.

[0095] 5. The charging device according to the embodiment of the present utility model integrates the telescopic line assembly as the power input end of the entire charging device, facilitating the user to adjust the length of the telescopic line in different usage scenarios, and further improving the flexibility of use.

[0096] 6.

[0097] 7. In the charging device according to the embodiment of the present utility model, by providing a concave accommodating groove and an outlet on the outer side wall of the first housing assembly, a storage space is provided for the movable end of the data cable, preventing the movable end of the data cable from being scattered outside in the non-use state and making the overall appearance neater and more beautiful; the movable end of the telescopic line assembly is designed with a magnetic component, which cooperates with the second magnetic component at the corresponding position on the housing assembly. This design enables the data cable to be quickly and stably adsorbed back into the accommodating groove when not in use, and can be easily pulled out by the user when needed, greatly improving the convenience of daily use.

[0098] 8. In the charging device according to the embodiment of the present utility model, the rotational connection between the second wireless charging component and the second support means that the second wireless charging component can be adjusted according to needs. In this solution, the second wireless charging component is the watch wireless charging module. By rotating the second wireless charging component to adjust the charging position, it can effectively prevent interference between the watch strap and other positions of the charging device during charging; the specially provided storage hole on the second support provides a fixed storage position for the second wireless charging component, which not only facilitates the storage of the component, avoids loss or damage when not in use, but also maintains the neat appearance of the overall device and improves the integrity of the product design.

[0099] 9. In the charging device according to the embodiment of the present utility model, by presetting an installation groove and an installation step on the second housing assembly, a standardized installation position and method are provided for the third wireless charging component, ensuring that the wireless charging component can be quickly and accurately installed in place; at least part of the third wireless charging component is located in the installation groove. Such a design helps to reduce the protrusion of the external contour and is beneficial to improving space utilization.

[0100] 10. In the charging device according to the embodiment of the present utility model, the heat dissipation performance of the charging device can be effectively improved by providing heat dissipation fins and / or heat dissipation holes. Specifically, the provision of heat dissipation fins increases the surface area of the housing surface. By increasing the air contact area, the heat generated inside can be more effectively conducted to the surrounding air, thereby accelerating the dissipation of heat energy and preventing heat accumulation. Similarly, the opening of heat dissipation holes provides an exhaust channel for hot air, promotes natural convection, and further enhances the cooling effect.
