Figure 3 is a schematic cross-sectional view of the electronic device and the wireless charging component in Figure 1.

[0010] In this embodiment, the wireless charging component 10 is used to carry and charge two electronic devices 20. The two electronic devices 20 are, for example, smartphones. The wireless charging component 10 includes a wireless charging stand 100 and a fan component 200.

[0011] In this embodiment, the wireless charging stand 100 includes a stand 110, a wireless charging module 120, and two cushions 150. In this embodiment, the stand 110 includes a base 1100, a top plate 1101, a support surface 111, a mounting surface 112, and an accommodating space 113. In this embodiment, the base 1100 is made of a metal, such as an aluminum alloy. In this embodiment, the base 1100 includes a bottom plate 1110 and a side plate 1120. The side plate 1120 stands on the bottom plate 1110. The top plate 1101 is provided on one side of the side plate 1120 away from the bottom plate 1110. The bottom plate 1110 forms the accommodating space 113 together with the side plate 1120 and the top plate 1101. The support surface 111 faces away from the accommodating space 113. Specifically, the support surface 111 is located on the top plate 1101 and faces away from the base 1100. The support surface 111 is used to support two electronic devices 20. The mounting surface 112 faces away from the receiving space 113 and is adjacent to the support surface 111. Specifically, the mounting surface 112 is located on one side of the side plate 1120.

[0012] In this embodiment, the wireless charging module 120 includes a circuit board 121 and a plurality of heat sources 122. The heat sources 122 are mounted on and electrically connected to the circuit board 121. The heat sources 122 are, for example, connectors conforming to the Universal Serial Bus Power Supply (USB PD) standard. The circuit board 121 is located in the receiving space 113. The wireless charging module 120 is used to charge two electronic devices 20. It should be noted that in other embodiments, the wireless charging module may include only one heat source.

[0013] The two cushions 150 are raised on the support surface 111 of the base 110. The two cushions 150 each support two electronic devices 20, forming a gap G between the support surface 111 and the two electronic devices 20. In other embodiments, the wireless charging component may support only one electronic device, and in such embodiments, the wireless charging base may include only one cushion.

[0014] In this embodiment, the wireless charging stand 100 further includes a heat dissipation block 160. The heat dissipation block 160 is located in the receiving space 113 and is in thermal contact with the heat source 122 and the base 1100. Specifically, opposite sides of the heat dissipation block 160 are in thermal contact with the heat source 122 and the base 1100, respectively. More specifically, opposite sides of the heat dissipation block 160 are in thermal contact with the heat source 122 and the bottom plate 1110, respectively. The heat dissipation block 160 is made of a thermally conductive material such as copper. In this embodiment, the heat source 122 passively dissipates heat, for example, by the heat dissipation block 160 and the base 1100. In another embodiment, the wireless charging stand may not include the heat dissipation block 160, and the amount of heat generated by the heat source may be dissipated only by convection.

[0015] 1 to 3, the fan component 200 includes a housing 210 and a fan 240. In this embodiment, the housing 210 includes a ventilation stand 225 and a ventilation lid 230. The ventilation stand 225 is provided on the mounting surface 112. The ventilation lid 230 is provided on one side of the ventilation stand 225 away from the mounting surface 112. In this embodiment, the housing 210 includes a first surface 213, a second surface 214, a third surface 215, a fourth surface 216, a first side surface 218, a first inclined surface 219, a second side surface 220, a second inclined surface 221, a plurality of first ventilation holes 211, a second ventilation hole 212, and a plurality of foreign object discharge ports 217.

[0016] The first surface 213 and the second surface 214 are opposed to each other. The first surface 213 is located on the ventilation base 225, and the second surface 214 is located on the ventilation cover 230. The first surface 213 facing the mounting surface 112 is closer to the base 110 than the second surface 214. The first surface 213 includes a mounting area 2130 and a ventilation area 2131 that are connected to each other. The mounting area 2130 is attached to the mounting surface 112. The first ventilation holes 211 are located in the ventilation area 2131 and exposed to one side of the support surface 111. The second ventilation holes 212 are located on the second surface 214. The first ventilation holes 211 are connected to the second ventilation holes 212.

[0017] The third surface 215 and the fourth surface 216 face each other and are located on the ventilation stand 225. The third surface 215 and the fourth surface 216 are connected to each other via the first surface 213 and the second surface 214 and are interposed between the first surface 213 and the second surface 214. The third surface 215 is connected to the ventilation area 2131 on the first surface 213. The fourth surface 216 is connected to the attachment area 2130 on the first surface 213. In this embodiment, the fourth surface 216 is located below the third surface 215 along the gravity direction W, for example. By being located on the fourth surface 216, foreign matter such as dust and moisture in the air entering the housing 210 through the first ventilation hole 211 or the second ventilation hole 212 is discharged from the foreign matter discharge port 217 to the outside of the housing 210 by gravity.

[0018] The first side 218 and the second side 220 stand on opposite sides of the third surface 215 and are parallel to each other. Opposite sides of the first side 218 are connected to the third surface 215 and the first slope 219, respectively. Opposite sides of the second side 220 are connected to the third surface 215 and the second slope 221, respectively. The first slope 219 and the second slope 221 stand on opposite sides of the fourth surface 216. Opposite sides of the first slope 219 are connected to the first side 218 and the fourth surface 216, respectively. Opposite sides of the second slope 221 are connected to the second side 220 and the fourth surface 216, respectively. A distance between one side of the first slope 219 connected to the first side 218 and one side of the second slope 221 connected to the second side 220 is greater than a distance between one side of the first slope 219 connected to the fourth surface 216 and one side of the second side 220 connected to the fourth surface 216. Due to the guidance of the first slope 219 and the second slope 221, foreign matter is more easily discharged from the inside of the housing 210 to the outside of the housing 210 through these foreign matter discharge ports 217. However, in other embodiments, the housing may not include the first slope 219 and the second slope 221, and the first side and the second side may extend from the third surface to the fourth surface.

[0019] The fan 240 is disposed in the housing 210. Specifically, in this embodiment, the fan 240 is fixed to one side of the vent cover 230 close to the vent stand 225. The fan 240 is, for example, an axial fan.

[0020] In this embodiment, the object outlets 217 are uniformly located on the fourth surface 216, as shown in FIG. 2. In other embodiments, the object outlets may be non-uniformly located on the fourth surface. Alternatively, in other embodiments, the housing may include only one object outlet. Alternatively, in other embodiments, the housing may not include any object outlets 217.

[0021] In this embodiment, as shown in FIG. 2, the first vent holes 211 are unevenly positioned in the ventilation area 2131 of the first surface 213, so that the ventilation base 225 can be conveniently attached to the mounting surface 112. Specifically, the portion of the ventilation area 2131 where the first vent holes 211 are not provided can be used to install fasteners (e.g., screws or bolts) that penetrate the mounting surface 112 and the ventilation base 225. In addition, in another embodiment, the ventilation base can be fixed to the adhesive by an adhesive, and the first vent holes can be uniformly positioned in the ventilation area of ​​the first surface. Alternatively, in another embodiment, the housing can include only one first vent hole. Alternatively, in another embodiment, the housing can be a plate, and the fan can be supported by the housing and exposed to the outside, so that the housing does not need to include the first vent hole 211 and the second vent hole 212.

[0022] In this embodiment, the receiving space 113 does not connect these first vent hole 211 and second vent hole 212. That is, the base 110 of the wireless charging base 100 does not have any holes or openings for the passage of fluid.

[0023] The fan 240 is used to guide air to the support surface 111 through at least a part of the first vents 211 and the second vents 212. The air guided by the fan 240 is used to cool the base 1100 and the electronic device 20. That is, the heat generated by the heat source 122 in the base 1100 is absorbed by the heat dissipation block 160, and then the heat dissipation block 160 conducts the heat to the base 1100. Then, the air guided by the fan 240 cooperates in cooling the base 1100. Note that in this embodiment, no fan is provided in the accommodation space 113, and the heat source 122 is passively dissipated by the heat dissipation block 160 and the base 1100. However, the fan 240 located outside the accommodation space 113 cools the base 1100, so that the base 1100 can more effectively dissipate the heat absorbed from the heat dissipation block 160 to the outside.

[0024] Referring to FIG. 4, FIG. 4 is a schematic cross-sectional view of a part of the electronic device and the wireless charging component in FIG. 1. In this embodiment, the fan 240 has an intake mode and an exhaust mode. When the fan 240 is in the intake mode, the fan 240 is used to guide air from at least some of these first vents 211 to the second vents 212 along the first flow direction D1. For example, when the wireless charging component 10 according to the present invention is applied to a vehicle electronic control system, the passengers on the vehicle are usually located on one side of the first vents 211 away from the second vents 212. Therefore, when the fan 240 is in the intake mode, the hot air does not flow to the passengers, but is guided from the first vents 211 to the second vents 212. In this way, the passengers on the vehicle have a more favorable user experience with the wireless charging component 10.

[0025] When the fan 240 is in the exhaust mode, the fan 240 is used to guide air along a second flow direction D2 from the second vents 212 to at least some of these first vents 211. When the fan 240 is in the exhaust mode, the air guided by the fan 240 is more concentrated on the base 1100 and the electronic device 20, so as to cool the base 1100 and the electronic device 20 more effectively.

[0026] In this embodiment, as shown in Fig. 3, these first vent holes 211 are farther from the fourth surface 216 than the second vent holes 212. Alternatively, at least some of the first vent holes 211 are located above the second vent holes 212 along the gravity direction W. In this manner, foreign matter in the air guided from the first vent holes 211 to the second vent holes 212 in the housing 210 can be more easily discharged to the outside of the housing 210 through the foreign matter discharge port 217. However, in other embodiments, the first vent holes may be closer to the fourth surface than the second vent holes, and foreign matter in the air guided from the second vent holes to the first vent holes in the housing can be more easily discharged to the outside of the housing through the foreign matter discharge port.

[0027] According to the wireless charging component disclosed in the above embodiment, the housing of the fan component is provided on one side of the base, and the fan is used to guide air to the support surface. Therefore, the air guided by the fan effectively cools the electronic device carried on the wireless charging base. In addition, since the fan of the fan component does not need to be provided in the accommodation space of the wireless charging base, no vent is provided on the wireless charging base, and foreign objects can be prevented from entering the wireless charging base. In addition, the air guided by the fan to the support surface cools the wireless charging base in addition to cooling the electronic device carried on the support surface. In this way, it is possible to make the wireless charging base comply with the foreign object protection grade while effectively cooling the wireless charging base and the electronic device.

[0028] For example, the wireless charging component according to the present invention has a foreign object protection rating of IP54.

[0029] In one embodiment of the present invention, the wireless charging component of the present invention can be applied to in-vehicle devices, such as autonomous vehicles, electric vehicles, and semi-autonomous vehicles.

[0030] The present invention has been disclosed above in each of the above embodiments, but is not limited thereto. Any person skilled in the art can make appropriate changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention is governed by that specified in the claims attached hereto. [Explanation of symbols]
