[0027] To make the objectives, technical solutions, and technical effects of the embodiments of this utility model clearer, the technical solution of the processing box of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only one preferred embodiment of this utility model, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.

[0028] As shown in Figures 1-3, this utility model provides a wireless charging device 10, including a housing 100, a charging module 110, a heat dissipation module 120, and a power input line 130. The housing 100 includes an upper housing 101 and a lower housing 102 in the vertical direction. The housing 100 is made of non-metallic materials to reduce production costs; preferably, it is made of plastic. The charging module 110 is disposed within the housing 100 and includes a circuit board 111 and a charging assembly 112. The circuit board 111 includes a power supply element, a control element, and a power conversion element. The power supply element is responsible for converting the input AC power into DC power suitable for wireless charging (AC / DC conversion), providing a stable power supply to the entire transmitter. The control element is responsible for controlling the entire wireless charging process. The power conversion element is responsible for converting the DC power output from the power supply module into high-frequency AC power (DC / high-frequency AC conversion) so that energy can be transferred to the receiver through electromagnetic induction. Circuit board 111 is electrically connected between input line 130 and charging component 112. Charging component 112 is specifically a coil composed of enameled wire. Charging module 110 is supported by upper housing 101, and the interior of upper housing 101 forms a receiving portion 101a for accommodating charging module 110. Figure 3 and Figure 5 As shown, the receiving part 101a has an upward opening 101b in the vertical direction, and a cover plate 103 is provided at the opening 101b of the upper housing 101 as the operating surface of the charging device. When the wireless charging device 10 charges an external electronic device that needs to be charged, the electronic device to be charged can be placed on the cover plate 103 to charge. The wireless charging device 10 also has a magnetic attraction module inside to prevent the electronic device to be charged from falling off the wireless charging device 10. The heat dissipation module 120 is used to dissipate heat from the circuit board 111 and the charging component 112 or one of them to maintain the temperature balance inside the wireless charging device 10, thereby protecting the electronic components of the wireless charging device 10 and extending the service life of the wireless charging device 10.

[0029] The heat dissipation module 120 includes a heat-conducting component and a heat dissipation shell. Specifically, the heat dissipation shell is separately disposed from the housing 100. The heat dissipation shell is fitted onto the outer side wall of the housing 100. The heat-conducting component connects the circuit board 111 inside the wireless charging device 10 and the heat dissipation shell outside the wireless charging device 10, thereby establishing a heat conduction path between the circuit board 111 and the heat dissipation shell. This allows the heat generated in the wireless charging device 10 to be conducted from the inside of the wireless charging device 10 to the outside of the wireless charging device 10, and then dissipated into the air through the airflow outside the wireless charging device 10, thereby achieving the purpose of heat dissipation.

[0030] Specifically, such as Figure 3-4 As shown, the heat-conducting components include, but are not limited to, a heat-conducting plate 121 and a heat-conducting metal sheet 122. The heat-conducting plate 121 contacts the circuit board 111 in the vertical direction. The heat-conducting plate 121 is made of a heat-conducting material; specifically, it is made of heat-conducting metal or heat-conducting resin. Preferably, it is made of aluminum. The heat-conducting metal sheet 122 is made of metal sheet; preferably, it is made of copper. The heat dissipation shell is the shell 123 of the wireless charging device 10. The shell 123 covers the periphery of the support 100. The shape and size of the shell 123 are adapted to the shape and size of the periphery of the support 100. For example, when the periphery of the shell 100 is cylindrical, the shell 123 is annular. The shell 123 is made of metal; preferably, it is made of aluminum. The shell 123 is electrically connected to the ground terminal in the circuit board 111 or the ground wire in the power input line 130.

[0031] like Figure 5 As shown, the heat-conducting plate 121 is located at the bottom of the circuit board 111 and contacts the heat-conducting metal sheet 122 in the vertical direction. The heat generated by the circuit board 111 during operation is absorbed by the heat-conducting plate 121 and transferred to the outer shell 123 through the heat-conducting metal sheet 122. The outer shell 123 dissipates the heat into the air outside the wireless charging device 10 and is carried away by the airflow, thereby achieving the purpose of heat dissipation.

[0032] like Figure 4-5As shown, the heat-conducting metal sheet 122 includes a first heat-conducting portion 122a and multiple second heat-conducting portions 122b. The multiple second heat-conducting portions 122b can respectively transfer heat to the outer casing 123 to improve the heat dissipation efficiency. A mounting post 102a is provided inside the lower casing 102, and a through hole 102b is opened on the side wall of the lower casing 102. The first heat-conducting portion 122a is installed inside the lower casing 102 via the mounting post 102a. The first heat-conducting portion 122a is located below and in contact with the heat-conducting plate 121 in the vertical direction. The heat-conducting plate 121 is located below and in contact with the circuit board 111 in the vertical direction; that is, the circuit board 111, the heat-conducting plate 121, and the first heat-conducting portion 122a are all located inside the lower casing 102 and arranged sequentially in the vertical direction. In this embodiment, the thermally conductive metal sheet 122 includes two second thermally conductive portions 122b. These two portions 122b are supported on the sidewall of the lower housing 102 and at least partially pass through the through-hole 102b. The two second thermally conductive portions 122b are in contact with both ends of the first thermally conductive portion 122a, and also in contact with the outer casing 123. Thus, the heat generated by the circuit board 111 can be transferred vertically to the thermally conductive metal sheet 122 via the thermally conductive plate 121 and the first thermally conductive portion 122a, and then horizontally to the outer casing 123 via the first thermally conductive portion 122a and the second thermally conductive portion 122b, and dissipated into the air outside the wireless charging device 10. That is, the heat conduction path of the wireless charging device 10 includes bidirectional heat dissipation paths in both the vertical and horizontal directions, which helps to achieve heat dissipation of the wireless charging device 10.

[0033] In this embodiment, the circuit board 111 and the heat dissipation module 120 are supported by the lower housing 102. In other words, the heat dissipation module 120 is used to dissipate heat from the circuit board 111. In other embodiments, the charging component 112 and the heat dissipation module 120 may also be mounted on the upper housing 101.

[0034] Furthermore, such as Figure 5 and Figure 6 A heat insulation layer 140 is provided between the charging component 112 and the circuit board 111 to reduce the heat transfer between the circuit board 111 and the charging component 112. Specifically, the heat insulation layer 140 is composed of heat insulation cotton and has a thickness of 0.5-2mm.

[0035] Functions and beneficial effects:

[0036] The heat dissipation module 120 improves the heat dissipation efficiency of the wireless charging device 10, effectively extending the lifespan of its internal electronic components. Furthermore, compared to existing technologies, the improved heat dissipation efficiency of the wireless charging device 10, achieved through the heat dissipation module 120, reduces the use of thermally conductive metal materials, thereby lowering the production cost of the wireless charging device 10.
