The second support plate 250 is substantially parallel to the XY plane, and the four sides of the second support plate 250 are respectively fixedly connected to the first side wall 230, the second side wall 240, the third side wall and the fourth side wall, so that the internal space of the second shell is divided into a second installation space 201 and a second receiving space 202, and the second installation space 201 and the second receiving space 202 are arranged along the Z direction. The second installation space 201 is located on the side of the second support plate 250 facing the first plate 210, and the second receiving space 202 is located on the side of the second support plate 250 facing the second plate 220. The second coil module 260 is located in the second installation space 201 and is fixed on the second support plate 250. The second installation space 201 extends to the outer surface of the first side wall 230, so that the first side wall 230 is provided with a second opening, that is, the second installation space 201 is an open space, so that when the second body 20 rotates, the third body 30 can enter the second installation space 201 from the second opening and can exit from the second installation space 201.

[0050] like Figure 2 and Figure 3 As shown, in one embodiment, the first shell and the second shell are rotatably connected by a hinge 190. The hinge 190 is connected to the intersection of the first side plate 130 and the second side plate 140 of the first shell, and the hinge 190 is connected to the intersection of the first side wall 230 and the second side wall 240 of the second shell.

[0051] like Figure 3As shown, the third housing includes a top plate 310 and a bottom plate 320 disposed opposite to each other, and a side wall 330 connected between the top plate 310 and the bottom plate 320. The top plate 310 and the bottom plate 320 are roughly parallel. The third housing is a rectangular parallelepiped or a cube structure. In another embodiment, the third housing can also be cylindrical or other shapes, which are not specifically limited here. The side wall 330 is fixedly connected to the hinge 190, so that when the first body 10 and the second body 20 rotate around the hinge 190, the third body 30 can be stationary relative to the hinge 190.

[0052] like Figure 5 and Figure 6 As shown, in one embodiment, the third body 30 includes a third support plate 350, and the third support plate 350 is installed in the third shell. The third support plate 350 is substantially parallel to the XY plane, and the periphery of the third support plate 350 is fixed to the side peripheral wall 330, so that the third support plate 350 divides the internal space of the third shell into a first chamber 301 and a second chamber 302 arranged along the Z direction. The third coil module 360 ​​is located in the first chamber 301, and the circuit board 340 is located in the second chamber 302.

[0053] like Figure 5 and Figure 6 As shown, in one embodiment, the third coil module 360 ​​includes a third coil 361 and a third magnetic isolation plate. The third magnetic isolation plate is fixed on the third support plate 350, and the third coil module 360 ​​is fixed on the side of the third magnetic isolation plate away from the third support plate 350.

[0054] In one embodiment, a heat conducting layer is provided between the circuit board 340 and the base plate 320 , and the material may be silicone grease with a high thermal conductivity, so that the heat generated by the circuit board 340 can be transferred to the base plate 320 and then to the external environment.

[0055] In one embodiment, the circuit board 340 is electrically connected to the first coil module 160, the second coil module 260 and the third coil module 360, so that the circuit board 340 can control the operation of the first body 10, the second body 20 and the third body 30. An interface is provided on the third housing so that the wireless charging device 1 can be electrically connected to an external electronic device or power source. Alternatively, an interface can be provided on the first body 10 or the second body 20 so that the wireless charging device 1 can be electrically connected to an external electronic device or power source.

[0056] like Figure 1 and Figure 3As shown, in one embodiment, in the first state, the first side panel 130 and the first side wall 230 are fitted, and the first opening and the second opening are connected, so that the first receiving space 102 and the second receiving space 202 are connected. Part of the structure of the third body 30 is located in the first receiving space 102, and the remaining structure is located in the second receiving space 202. The first body 10 and the second body 20 can both charge the device to be charged. In the first state, two devices to be charged can be placed on the first panel 110 and the first plate 210 respectively, and the wireless charging device 1 can charge two devices to be charged. When it is necessary to charge three devices to be charged, the first body 10 and the second body 20 are rotated around the hinge 190 respectively until the second side panel 140 and the second side wall 240 are fitted. During the switching process from the first state to the second state, the third body 30 is stationary relative to the hinge 190. In the second state, the third body 30 is completely located outside the first shell and the second shell. Three devices to be charged can be placed on the first panel 110 , the first plate 210 , and the top plate 310 , respectively, and the wireless charging device 1 can charge the three devices to be charged.

[0057] The wireless charging device 1 of the present application is designed to rotate the first body 10 and the second body 20 relative to the hinge 190, and the third body 30 is fixed to the hinge 190. The third body 30 can be stored in the first body 10 or the second body 20, which is convenient for storage, saves space, and improves product competitiveness. The first body 10, the second body 20 and the third body 30 are respectively provided with a first coil module 160, a second coil module 260 and a third coil module 360, so that the wireless charging device 1 can charge two devices to be charged in the first state, and can charge three devices to be charged in the second state, enriching the use scenarios. In the first state, the first body 10 and the second body 20 are arranged side by side to reduce heat superposition and prevent the heat dissipation of the first body 10, the second body 20 and the two devices to be charged. In the second state, the first body 10, the second body 20 and the third body 30 are arranged side by side without stacking, which can also reduce heat superposition and prevent the heat dissipation of the first body 10, the second body 20, the third body 30 and the three devices to be charged.

[0058] like Figure 7 and Figure 8As shown, in one embodiment, a circuit board 340 is provided inside the third body 30, while the third support plate 350 and the third coil module 360 ​​are omitted. It can be understood that the third shell separates the circuit board 340 from the first coil module 160 and the second coil module 260, and the third shell can effectively isolate the heat emitted by the circuit board 340, avoid heat transfer between the first coil module 160, the second coil module 260 and the circuit board 340, and can reduce costs. In the second state, the first body 10, the second body 20 and the third body 30 are arranged side by side and non-stacked, further effectively isolating the heat transfer between the circuit board 340 and the first coil module 160, the second coil module 260.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
