[0036] The embodiments of this utility model are described in detail below with reference to the accompanying drawings. The drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of this utility model.

[0037] Example 1

[0038] Reference Figures 1 to 13 A multi-functional power supply device with dual wireless charging function includes a power supply housing 1. A clock 35 and two wireless charging docks 2 are provided on the side of the power supply housing 1. A circuit board 3 is provided inside the power supply housing 1. A power socket 4 and a connector are provided on the circuit board 3. The power socket 4 and the connector are exposed on the top of the power supply housing 1 and form a power socket 111 and a charging socket 112 respectively.

[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The power supply housing 1 includes an outer shell 11 and a bottom cover 12. The bottom of the outer shell 11 is hollowed out. The left and right corresponding side walls of the outer shell 11 are inclined in a V-shape and each of the two side walls has a U-shaped opening. The inclination angle α of the left and right side walls of the outer shell 11 is 15°-25°. The front and back corresponding side walls of the outer shell 11 are also inclined in a V-shape. A rectangular opening is provided on the front side wall of the outer shell 11. The bottom cover 12 is placed on the bottom of the outer shell 11 and forms an inner cavity. Four feet 124 are spaced apart on the bottom surface of the bottom cover 12. Two sets of heat dissipation holes 123 and multiple sound outlet holes 122 are provided on the bottom wall of the bottom cover 12. The multiple sound outlet holes 122 are concentrated in the center of the bottom cover 12. All sound outlet holes 122 are located between the two sets of heat dissipation holes 123. A battery compartment is also provided at the bottom of the bottom cover 12. A battery cover 121 is provided on the top of the battery compartment. The entire power supply housing 1 is flat-topped quadrangular pyramid.

[0040] Reference Figure 1 , Figure 3 and Figure 9 The clock 35 is specifically embedded in the rectangular opening on the front of the housing 11. Since the front of the housing 11 is tilted backward, the clock 25 is also tilted accordingly, making it convenient for users to check the time. The battery in the battery compartment is electrically connected to the clock 35 to power the clock 35. The clock 35 and the front of the housing 11 are also covered by a transparent cover plate 351. The clock 35 uses an LED digital display screen and has alarm clock and dimming functions.

[0041] Reference Figure 1 , Figure 3 and Figure 4The wireless charging base 2 can be selected from existing wireless charging structures on the market. It mainly includes a lens, a strong magnetic attraction, a charging induction coil, a magnetic plastic shell, and a temperature control chip. It primarily uses a power adapter to convert AC power to DC power, which is then processed by internal circuitry into high-frequency AC power to supply the charging induction coil. The high-frequency AC power generates an alternating magnetic field in the charging induction coil. When a wirelessly charging-enabled device (such as a mobile phone) approaches, the receiving coil inside the device senses the magnetic field and generates an induced current, which is then converted by the device's internal circuitry to charge the battery. The magnetic plastic shell and strong magnetic attraction help align the device with the charging base and ensure a stable connection, guaranteeing charging efficiency. Both wireless charging bases 2 have built-in NTC temperature detection modules; if the temperature exceeds 45°C, the output frequency automatically decreases. In this invention, the two wireless charging bases 2 are respectively embedded in the U-shaped openings on the left and right corresponding side walls of the outer shell 11. Because the left and right corresponding side walls of the outer shell 11 are arranged in a V-shape with an inclination, the two wireless charging bases 2 are also tilted relative to the left and right side walls of the outer shell 11, allowing for vertical tilting for magnetic charging of mobile phones.
