[0042] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0043] refer to Figure 1 and Figure 2 The present application discloses a wireless charging stand 10, which can be used to charge electronic devices with wireless charging function. The electronic devices with wireless charging function can be smart phones, tablet computers, smart watches, bracelets, etc. Figure 3 and Figure 4The wireless charging stand 10 includes a housing 100, a first coil module 200, a circuit board 300 and a first fan 400. The housing 100 is used to install the first coil module 200, the circuit board 300 and the first fan 400 and can position, support and protect these components. The housing 100 includes a carrier 110, a charging area 120 and a first mounting seat 130. The charging area 120 can be used to place electronic devices to wirelessly charge the electronic devices. The charging area 120 is connected to the carrier 110 and forms a mounting cavity 101 with the carrier 110. The charging area 120 can be integrally formed with the carrier 110, or it can be assembled. In some embodiments, the charging area 120 is rectangular, and in other embodiments, the charging area 120 can be circular, runway-shaped, etc. Among them, the runway shape refers to a figure formed by two semicircular arcs connected to the opposite sides of the rectangle.

[0044] Combination Figure 1 , Figure 5 and Figure 6 The first mounting seat 130 is connected to the carrier 110 and can rotate relative to the carrier 110 to a first state and a second state, and the first mounting seat 130 is provided with a first air flow channel 131. Figure 7 , Figure 8 and Fig. 9 In one embodiment, the first airflow channel 131 passes through two opposite ends of the first mounting seat 130 and forms through holes at two opposite ends of the first mounting seat 130 so that the air in the first mounting seat 130 can circulate with the outside air. In other embodiments, the through hole formed by the first airflow channel 131 in the first mounting seat 130 can be located at other positions. The first coil module 200 is disposed in the mounting cavity 101 and is covered by the charging area 120. The circuit board 300 is disposed in the carrier 110 and is electrically connected to the first coil module 200. The first fan 400 is connected to at least one of the carrier 110 and the first mounting seat 130, and the first fan 400 is electrically connected to the circuit board 300. The first circuit board 300 can control the working state of the first fan 400. Reference Figure 8 and Fig. 9 When the electronic device is placed on the wireless charging stand 10 for charging, in the first state, the surface of the electronic device and the first airflow channel 131 are isolated by the first mounting stand 130, and the first fan 400 can guide the outside air into the mounting cavity 101 for heat exchange. Fig.10 and Fig.11 In the second state, the outlet of the first air flow channel 131 of the first mounting seat 130 is exposed to the side of the charging area 120 away from the first coil module 200, and the first fan 400 can guide the air in the first air flow channel 131 to flow to the surface of the electronic device and perform heat exchange with the electronic device.

[0045] Further, refer to Figure 8 In the first state, the outer surface of the charging area 120 is flush with the outer surface of the first mounting seat 130, referring to Fig.11 In the second state, the end of the first mounting seat 130 close to the charging area 120 protrudes from the outer surface of the charging area 120. Figure 3 and Figure 4 In some embodiments, the carrier 110 is roughly rectangular, the charging area 120 is rectangular, and a step structure is provided around the carrier 110. The step structure extends along the extension direction of one side of the rectangle where the charging area 120 is located, and the side of the rectangle where the charging area 120 is located is arranged parallel to the rotation axis direction of the first mounting seat 130. The charging area 120 is arranged protruding from the carrier 110, and the first mounting seat 130 is arranged at the step structure and can rotate relative to the carrier 110 around the side of the rectangle at the step structure.

[0046] Further, combined with Figure 8 In some embodiments, the first fan 400 is installed in the first airflow channel 131, and the wireless charging stand 10 can be placed on a horizontal support surface during normal use. In the first state, the side of the first mounting base 130 that is away from the horizontal plane is parallel to the horizontal plane, and in the second state, the side of the first mounting base 130 that is away from the horizontal plane is inclined to the horizontal plane. Fig. 9 In the first state, one end of the first mounting seat 130 close to the charging area 120 is engaged with the edge of the charging area 120, so that the outer surface of the first mounting seat 130 on the same side as the charging area 120 forms a continuous surface with the outer surface of the charging area 120, so that the first mounting seat 130 has a high appearance integrity in the first state. The rotation connection between the first mounting seat 130 and the carrier 110 can have a variety of structural forms. For example, one of the first mounting seat 130 and the carrier 110 is provided with a rotating shaft, and the other is provided with an axial hole that can be rotatably matched with the rotating shaft, so that the first mounting seat 130 can rotate relative to the carrier 110. In other embodiments, one of the first mounting seat 130 and the carrier 110 can be provided with an arc guide rail, and the other is provided with an arc guide groove, and the arc guide rail and the arc guide groove are slidably matched, so that the first mounting seat 130 can rotate relative to the carrier 110 to the first state and the second state.

[0047] Of course, in other embodiments, the charging area 120 may have other shapes such as circular, triangular, runway, etc. The carrier 110 may have other shapes and be able to engage with the edge of the charging area 120 in the first state, so that the first mounting seat 130 has better appearance characteristics of the wireless charging stand 10 in the first state. Of course, in other embodiments, the first fan 400 may be installed in the mounting cavity 101 of the carrier 110 or other positions of the carrier 110, and the air duct structure is arranged so that in the second state, the first fan 400 can guide the air in the first airflow channel 131 to flow to the electronic device and perform heat exchange with the electronic device. Further, refer to Fig.11 In some embodiments, in the second state, the first airflow channel 131 is connected to the mounting cavity 101, and the first fan 400 can guide the air in the mounting cavity 101 to exchange heat with the air in the first airflow channel 131, thereby more effectively guiding the heat generated by the first coil module 200 to be dissipated to the outside air, so as to improve the heat dissipation performance of the wireless charging stand 10. It should be understood that the first fan 400 guiding the air in the mounting cavity 101 to exchange heat with the air in the first airflow channel 131 can include two forms. Taking the first mounting seat 130 in the first state as an example, in one embodiment, the first fan 400 can extract the air in the mounting cavity 101 and flow it out to the outside of the first mounting seat 130 through the first airflow channel 131. In another embodiment, the first fan 400 can extract the outside air from the first airflow channel 131 and send it to the mounting cavity 101, and then flow out of the carrier 110 from the mounting cavity 101.

[0048] In some embodiments, the first fan 400 is a centrifugal fan, and the rotating shaft of the first fan 400 is substantially parallel to the thickness direction of the first mounting seat 130. The arrangement of the centrifugal fan is conducive to the lightweight design of the wireless charging seat 10. When the first mounting seat 130 is in the first state, a geometric plane perpendicular to the thickness direction of the first mounting seat 130 is made, and the geometric plane is used as a reference plane. The orthographic projection of the first fan 400 on the reference plane is arranged at an interval with the orthographic projection of the first coil module 200 on the reference plane. This arrangement avoids stacking the first fan 400 on the first coil module 200, which is conducive to the lightweight design of the wireless charging seat 10.

[0049] Further, the carrier 110 or the first mounting seat 130 of the housing 100 may be provided with an electrical connection interface, which is electrically connected to the circuit board 300, and the electrical connection interface is used to connect an external power source to power the wireless charging seat 10, so that the wireless charging seat 10 can be used to charge electronic devices. The electrical connection structure can be a USB interface, or a cable with a plug, etc. Further, the carrier 110 or the first mounting seat 130 of the housing 100 may be provided with an indicator light to indicate the working status of the wireless charging seat 10. Further, a non-slip pad or the like may be provided on the side of the carrier 110 that is away from the charging area 120, so that when the wireless charging seat 10 is placed on a support such as a desktop, the wireless charging seat 10 will not slide easily.

[0050] Further, refer to Figure 3 , Figure 4 and Fig. 9 The wireless charging stand 10 includes a magnetic isolation sheet 510 disposed in the mounting cavity 101, and the first coil module 200 is stacked on the magnetic isolation sheet 510. The magnetic isolation sheet 510 can be made of ferrite wave absorbing material, which has excellent magnetic conductivity, can increase the magnetic flux of the first coil module 200 and reduce the loss of the first coil module 200, and can make the magnetic flux lines tightly surround the surrounding area centered on the magnetic isolation sheet 510 to increase the electromagnetic induction intensity and improve the electromagnetic conversion efficiency.

[0051] Furthermore, the wireless charging stand 10 includes a bracket 520 connected to the carrier 110, and the magnetic isolation sheet 510 is arranged on the bracket 520 and supported by the bracket 520. In some embodiments, part of the structure of the carrier 110 is made of metal materials such as aluminum alloy, and the bracket 520 can conduct the heat generated by the first coil module 200 to the metal part of the carrier 110. During the wireless charging process of the electronic device, this arrangement is conducive to conducting the heat generated by the first coil module 200 to the metal part of the carrier 110, and dissipating the heat generated by the first coil module 200 to the external air or conducting it to the support through the carrier 110. In the embodiment where the carrier 110 is made of non-metallic material, the bracket 520 can also improve the stability of the installation of the first coil module 200 and the magnetic isolation sheet 510.

[0052] Further, in some embodiments, the wireless charging stand 10 includes a heat insulation structure 530, which is connected to the carrier 110 and isolates the circuit board 300 from the first coil module 200. The material of the heat insulation structure 530 can be plastic, silicone, ceramic, glass fiber, asbestos, etc., and its thermal conductivity is low, so it can effectively reduce the heat conducted from the first coil module 200 to the circuit board 300 during wireless charging to prevent the electronic components on the circuit board 300 from being degraded or damaged due to excessive temperature. The above-mentioned wireless charging stand 10 can meet the needs of high-power wireless charging to shorten the wireless charging time. In some embodiments, the heat insulation structure 530 and the carrier 110 form a cavity 103 independent of the installation cavity 101, and the circuit board 300 is arranged in the cavity 103 to isolate the circuit board 300 from the first coil module 200. Further, in some embodiments, the cavity 103 formed by the heat insulating structure 530 is annular, and the circuit board 300 is annular and disposed in the cavity 103, that is, the circuit board 300 may be provided with a mounting hole that passes through the circuit board 300 and the heat insulating structure 530 may be passed through the mounting hole of the circuit board 300. Of course, in other embodiments, the heat insulating structure 530 may also be plate-shaped or in other structural forms.

[0053] When the power required for wireless charging of an electronic device is relatively small, the first mounting seat 130 can be in the first state, and the side of the wireless charging seat 10 where the charging area 120 is located presents a flat surface. Electronic devices such as smart phones, tablet computers, and smart watches can be placed in the charging area 120 for wireless charging. The first fan 400 can promote heat exchange between the air in the mounting cavity 101 and the first airflow channel 131 and the outside air, thereby dissipating the heat of the wireless charging seat 10.

[0054] When the power required for wireless charging of the electronic device is relatively large, the first mounting seat 130 rotates to the second state relative to the carrier 110. For electronic devices such as smart phones and tablet computers that have a wireless charging function and are slightly larger in size, when the electronic device is placed in the charging area 120 for charging, the first mounting seat 130 supports the electronic device and allows a gap to exist between the electronic device and the outer surface of the charging area 120. During the wireless charging process of the electronic device, the first fan 400 guides the air in the gap and the first airflow channel 131 to exchange heat with the outside air, so that the heat between the wireless charging seat 10 and the electronic device can be dissipated to the ambient air in time, so as to improve the heat dissipation efficiency of the wireless charging seat 10 and the electronic device. Of course, during the wireless charging process of the wireless charging seat 10, the first fan 400 can also guide the air in the mounting cavity 101 to exchange heat with the outside air, so that the first coil module 200 can be effectively cooled. For electronic devices with wireless charging function and slightly smaller size, such as smart watches, wireless headphones, etc., when the electronic device is placed in the charging area 120 for charging, the electronic device can contact the outer surface of the charging area 120, and an air flow channel is formed on the periphery of the electronic device. The first fan 400 can guide the air in the first air flow channel 131 to flow to the electronic device for heat exchange, thereby improving the heat dissipation efficiency of the wireless charging stand 10.

[0055] With the wireless charging stand 10, electronic devices such as smart phones, smart watches, and wireless headphones with wireless charging functions can be placed in the charging area 120 for wireless charging. The wireless charging stand 10 can be adapted to a variety of models, which improves the convenience of use. Since the wireless charging stand 10 is provided with a first fan 400 and the first mounting seat 130 can rotate relative to the carrier 110 to switch between the first state and the second state, during the wireless charging of the electronic device, when the power required for charging is relatively small, the first mounting seat 130 can be in the first state, and the first fan 400 can guide the air in the mounting cavity 101 to exchange heat with the outside air, so that the wireless charging stand 10 can effectively dissipate heat; when the power required for charging is relatively large, the first mounting seat 130 is adjusted to the second state, and the first fan 400 can guide the air in the first airflow channel 131 to flow to the surface of the electronic device and perform heat exchange, so that the wireless charging stand 10 and the electronic device can be cooled to improve the heat dissipation efficiency. The heat dissipation duct of the wireless charging stand 10 is easy to design, has a better heat dissipation effect, and can meet the needs of high-power wireless charging to shorten the wireless charging time.

[0056] refer to Fig.12In other embodiments, the first fan 400 can be arranged on the carrier 110, and another coil module 540 is arranged in the first airflow channel 131, and the other coil module 540 is electrically connected to the circuit board 300. The electronic device can be placed on the first mounting seat 130 and the other coil module 540 can charge the electronic device. The arrangement of the first coil module 200 and the other coil module 540 can increase the area of ​​the inductive charging area of ​​the wireless charging seat 10, so that the wireless charging seat 10 can wirelessly charge two or more electronic devices at the same time. For example, the wireless charging module provided with the first coil module 200 and the other coil module 540 can charge a smart phone and a smart watch at the same time. Similarly, when the first mounting seat 130 is provided with another coil module 540, the first mounting seat 130 can also rotate relative to the carrier 110 to the first state and the second state, and in the second state, the first fan 400 is used to guide the air in the first airflow channel 131 to flow to the electronic device and perform heat exchange with the electronic device to improve the heat dissipation performance of the wireless charging seat 10.

[0057] Further, refer to Figure 3 and Figure 4 The wireless charging stand 10 includes a second mounting stand 140, combined with Fig.13 and Fig.14 The second mounting seat 140 and the first mounting seat 130 are respectively disposed at opposite ends of the carrier 110, and the second mounting seat 140 is provided with a second air flow channel 141. Fig.15 , Fig.11, when the second mounting seat 140 is in the second state, the first fan 400 can guide the air flow of the second air flow channel 141 to the outer surface of the charging area 120. In some embodiments, the shape of the second mounting seat 140 is the same as or similar to the shape of the first mounting seat 130. For example, in the application embodiment, the first mounting seat 130 and the second mounting seat 140 have the same shape, and the two are symmetrically arranged at opposite ends of the charging area 120, so that the first mounting seat 130 and the second mounting seat 140 can be assembled into a common component, which is convenient for the installation and replacement of the first mounting seat 130 and the second mounting seat 140. Of course, the shape of the second mounting seat 140 can be different from that of the first mounting seat 130. The second mounting seat 140 can be rotatably connected to the carrier 110, or it can be relatively fixed to the position of the carrier 110. When the first mounting seat 130 is in the second state, one end of the second mounting seat 140 close to the charging area 120 protrudes out of the charging area 120, and relatively large electronic devices can be supported by the second mounting seat 140 and the first mounting seat 130, and the electronic devices can form a gap with the outer surface of the charging area 120, and the gap is connected to the second airflow channel 141, and the second airflow channel 141 can be connected or not connected to the mounting cavity 101. The second airflow channel 141 forms a through hole in the second mounting seat 140 so that the air in the second mounting seat 140 can exchange heat with the outside air through the through hole. Other structural forms of the second mounting seat 140 can refer to the first mounting seat 130, and will not be repeated here.

[0058] Further, in the embodiment of the present application, the second mounting seat 140 can rotate relative to the carrier 110 so that the outer surface of the second mounting seat 140 is flush with the outer surface of the charging area 120, such as Figure 8 and Fig. 9 As shown, or the end of the second mounting seat 140 close to the charging area 120 protrudes from the outer surface of the charging area 120, as shown Fig.11 When the power required for wireless charging of an electronic device is relatively small, the first mounting seat 130 is in the first state, and the end of the second mounting seat 140 close to the charging area 120 does not need to protrude from the outer surface of the charging area 120, that is, the second mounting seat 140 can also be in the first state, and the second airflow channel 141 is connected to the mounting cavity 101, that is, the side of the wireless charging seat 10 where the charging area 120 is located presents a flat surface, and electronic devices such as smart phones, tablet computers, and smart watches can be placed in the charging area 120 for wireless charging. The first fan 400 can promote heat exchange between the air in the mounting cavity 101 and the air in the first airflow channel 131 and the second airflow channel 141, thereby dissipating heat from the wireless charging seat 10.

[0059] When the power required for wireless charging of the electronic device is relatively large, the first mounting seat 130 is in the second state, and the second mounting seat 140 rotates relative to the carrier 110 and makes one end of the second mounting seat 140 close to the charging area 120 protrude from the outer surface of the charging area 120. For electronic devices with slightly larger sizes, such as smart phones and tablet computers, when the electronic device is placed in the charging area 120 for charging, the first mounting seat 130 and the second mounting seat 140 support the electronic device and make a gap between the electronic device and the outer surface of the charging area 120. During the process of wireless charging of the electronic device, the first fan 400 guides the air in the gap, the first airflow channel 131, and the second airflow channel 141 to flow relative to the outside air to achieve heat exchange, thereby allowing the heat between the wireless charging seat 10 and the electronic device to be dissipated to the ambient air in time to improve the heat dissipation efficiency of the wireless charging seat 10 and the electronic device. Of course, during the process of wireless charging of the wireless charging seat 10, the first fan 400 can also guide the air in the mounting cavity 101 to flow relative to the outside air to achieve heat exchange, so that the first coil module 200 can be effectively cooled. For electronic devices of slightly smaller size, such as smart watches, wireless headphones, etc., when the electronic device is placed in the charging area 120 for charging, the electronic device contacts the outer surface of the charging area 120, and an air flow channel is formed around the electronic device. The first fan 400 can guide the second air flow channel 141, the first air flow channel 131 and the air around the electronic device to produce relative flow with the outside air to achieve heat exchange, thereby improving the heat dissipation efficiency of the wireless charging stand 10.

[0060] Further, refer to Fig.11 When the first mounting seat 130 is in the second state, one end of the second mounting seat 140 close to the charging area 120 protrudes from the outer surface of the charging area 120 and is flush with the first mounting seat 130 on the side away from the first coil module 200. This structure enables a slightly larger electronic device to be stably placed on the wireless charging seat 10 and supported by the first mounting seat 130 and the second mounting seat 140 after the first mounting seat 130 is in the second state and the second mounting seat 140 is rotated, and a slightly smaller electronic device can still contact the charging area 120 for wireless charging, which will not be described in detail here.

[0061] Further, refer to Fig.12, the second air flow channel 141 may be provided with a second coil module 143, and the second coil module 143 is electrically connected to the circuit board 300. When the first mounting seat 130 is in the first state and the end of the second mounting seat 140 close to the charging area 120 does not protrude from the outer surface of the charging area 120, the arrangement of the first coil module 200 and the second coil module 143 can increase the area of ​​the inductive charging area of ​​the wireless charging seat 10, so that the wireless charging seat 10 can wirelessly charge two or more electronic devices at the same time. For example, the wireless charging seat 10 provided with the first coil module 200 and the second coil module 143 can charge a smart phone and a smart watch at the same time.

[0062] refer to Fig.11 In other embodiments, the second air flow channel 141 may be provided with a second fan 145, and the second fan 145 is electrically connected to the circuit board 300. The second fan 145 may be a centrifugal fan to facilitate the thin and light design of the wireless charging stand 10. Figure 8 In some embodiments, when the first mounting base 130 is in the first state and the end of the second mounting base 140 close to the charging area 120 does not protrude from the outer surface of the charging area 120, the first airflow channel 131, the mounting cavity 101 and the second airflow channel 141 are connected, and one of the first fan 400 and the second fan 145 extracts external air. After the external air flows through the mounting cavity 101 and undergoes heat exchange, it is guided by the other of the first fan 400 and the second fan 145 to be sent out of the wireless charging base 10. Reference Fig.11When the first mounting seat 130 is in the second state and the end of the second mounting seat 140 close to the charging area 120 protrudes from the outer surface of the charging area 120, one of the first fan 400 and the second fan 145 extracts external air, and the external air flows through the electronic equipment in the charging area 120 and undergoes heat exchange, and then is guided by the other of the first fan 400 and the second fan 145 into the housing 100, and then is guided to be sent out of the wireless charging seat 10. For example, the first fan 400 guides the external air into the first air flow channel 131, and the first air flow channel 131 is then guided by the first fan 400 or the second fan 145 to flow toward the electronic equipment in the charging area 120 for heat exchange, and the air after heat exchange is guided by the first fan 400 or the second fan 145 to flow into the second air flow channel 141, and then is guided by the second fan 145 to flow out of the second mounting seat 140. Of course, in this process, the air in the installation cavity 101 can also be guided by the first fan 400 and the second fan 145 to generate relative flow with the external air to achieve heat exchange, thereby improving the heat dissipation efficiency of the wireless charging stand 10. Of course, through the structural setting of the air duct, one of the first fan 400 and the second fan 145 can be omitted, that is, one of the first fan 400 or the second fan 145 can be used to guide the air to flow between the first airflow channel 131 and the second airflow channel 141.

[0063] Further, refer to Figure 3 and Figure 4The wireless charging stand 10 includes a third mounting seat 150 and a fourth mounting seat 160, which are respectively arranged at opposite ends of the carrier 110 and between the first mounting seat 130 and the second mounting seat 140. The first mounting seat 130, the third mounting seat 150, the second mounting seat 140, and the fourth mounting seat 160 are arranged in sequence along the circumference of the charging area 120. The third mounting seat 150 is provided with a third air flow channel 151, and the fourth mounting seat 160 is provided with a fourth air flow channel 161. When the first mounting seat 130 is in the second state, the outlet of the third air flow channel 151 close to the charging area 120 can be exposed to the charging area 120, and the outlet of the fourth air flow channel 161 close to the charging area 120 can be exposed to the charging area 120, that is, the third mounting seat 150 and the fourth mounting seat 160 can be in the second state respectively. The first fan 400 can guide the air of at least one of the third airflow channel 151 and the fourth airflow channel 161 to flow relative to the air in the space near the charging area 120 to achieve heat exchange. The provision of the third airflow channel 151 and the fourth airflow channel 161 can further improve the heat dissipation performance of the wireless charging stand 10, thereby enabling the wireless charging stand 10 to meet the requirements of higher-power wireless charging. The structure and form of the third mounting seat 150 and the fourth mounting seat 160 can be similar to those of the second mounting seat 140 and the first mounting seat 130, and will not be repeated here. The third mounting seat 150 can be rotatably connected to the carrier 110, or the position of the carrier 110 can be relatively fixed; the fourth mounting seat 160 can be rotatably connected to the carrier 110, or the position of the carrier 110 can be relatively fixed, and will not be repeated here.

[0064] Further, in some embodiments, the third mounting seat 150 can be rotated relative to the carrier 110 so that the outer surface of the third mounting seat 150 is flush with the outer surface of the charging area 120, or so that the end of the third mounting seat 150 close to the charging area 120 protrudes from the outer surface of the charging area 120. Further, the fourth mounting seat 160 can be rotated relative to the carrier 110 so that the outer surface of the fourth mounting seat 160 is flush with the outer surface of the charging area 120, or so that the end of the fourth mounting seat 160 close to the charging area 120 protrudes from the outer surface of the charging area 120. Further, when the first mounting seat 130 is in the first state, the first mounting seat 130, the second mounting seat 140, the third mounting seat 150, and the fourth mounting seat 160 are docked with the outer surface of the charging area 120 and are flush with the side of the charging area 120 facing away from the first coil module 200. Further, refer to Figure 1, when the first mounting seat 130 is in the first state, the first mounting seat 130, the third mounting seat 150, the second mounting seat 140, and the fourth mounting seat 160 are adjacent to each other in sequence and joined at the edges, and the edges of two adjacent ones are joined and flush with each other at the end away from the charging area 120. For example, the first mounting seat 130 and the third mounting seat 150 are flush with each other at the end away from the charging area 120, and the second mounting seat 140 and the fourth mounting seat 160 are flush with each other at the end away from the charging area 120. This arrangement enables a relatively large flat surface to be formed on the side where the charging area 120 is located, so as to stably support electronic devices of larger sizes. When the first mounting seat 130 is in the second state, the ends of the second mounting seat 140, the third mounting seat 150, and the fourth mounting seat 160 close to the charging area 120 protrude from the outer surface of the charging area 120 and are flush with the first mounting seat 130 on the side away from the first coil module 200. With this arrangement, the first mounting seat 130, the second mounting seat 140, the third mounting seat 150 and the fourth mounting seat 160 can support larger electronic devices more stably, and are conducive to forming a gap between the electronic devices and the outer surface of the charging area 120, so that the air in the gap can better flow relative to the outside air and exchange heat, thereby improving the heat dissipation performance of the wireless charging stand 10.

[0065] Further, refer to Figure 3, at least one of the third airflow channel 151 and the fourth airflow channel 161 is provided with a third fan 153, and the third fan 153 is electrically connected to the circuit board 300. When the first mounting seat 130 is in the second state, the first fan 400 can guide the air in the first airflow channel 131, the space near the charging area 120, and the second airflow channel 141 to flow relative to the outside air and perform heat exchange, and the third fan 153 can guide the air in the third airflow channel 151, the space near the charging area 120, and the fourth airflow channel 161 to flow relative to the outside air and perform heat exchange. Specifically, in the embodiment of the present application, the first mounting seat 130 is provided with a first fan 400, the second mounting seat 140 is provided with a second fan 145, and the third fan 153 includes two, and the two third fans 153 are respectively provided on the third mounting seat 150 and the fourth mounting seat 160. When the wireless charging stand 10 uses high power to wirelessly charge electronic devices, the first airflow channel 131, the space near the charging area 120, and the second airflow channel 141 form a heat dissipation channel, and the third airflow channel 151, the space near the charging area 120, and the fourth airflow channel 161 form another heat dissipation channel. The extension directions of these two heat dissipation channels can be perpendicular to each other or inclined to enable the wireless charging stand 10 to have better heat dissipation performance. Of course, in other embodiments, the third mounting seat 150 and the fourth mounting seat 160 do not have to be provided at the same time. In other embodiments, more structures similar to the third mounting seat 150 can also be provided to improve the performance of the wireless charging stand 10. Of course, the third fan 153 can be replaced by a coil module so that the wireless charging stand 10 can wirelessly charge more electronic devices at the same time.

[0066] It is understandable that when the wireless charging stand 10 includes more than three structures similar to the first mounting seat 130, any two first mounting seats 130 arranged opposite to each other can be regarded as constituting a functional group, and each functional group can be provided with a device similar to the first fan 400. In the first state, the first fan 400 can guide the outside air from one first mounting seat 130 in the functional group to flow to the mounting cavity 101 and perform heat exchange, and the air after heat exchange can be guided to flow into another first mounting seat 130 in the functional group. In the second state, the first fan 400 can guide the outside air from one first mounting seat 130 in the functional group to flow to the surface of the electronic device and perform heat exchange, and the air after heat exchange can be guided into another first mounting seat 130 in the functional group or directly flow to the external environment. For example, in the embodiment of the present application, the wireless charging stand 10 includes two functional groups, the first mounting seat 130 and the second mounting seat 140 constitute one functional group, and the third mounting seat 150 and the fourth mounting seat 160 constitute another functional group. The charging area 120 is rectangular in shape, wherein one functional group is arranged corresponding to two opposite sides of the rectangle, and another functional group is arranged corresponding to the other two opposite sides of the rectangle. Each functional group is provided with a device similar to the first fan 400 to guide the air to flow in the functional group. In other embodiments, when the number of the first mounting seats 130 is an odd number, for example, when the fourth mounting seat 160 is omitted, the wireless charging seat 10 can be provided with a third fan 153, which is arranged corresponding to those first mounting seats 130 that do not constitute a functional group and is used to guide the air to generate relative flow in the mounting cavity 101, the space near the charging area 120, and the first mounting seat 130 for heat exchange.

[0067] When the wireless charging stand 10 includes more than three structures similar to the first mounting seat 130, in the first state, two first mounting seats 130 adjacent to each other in sequence among the three or more first mounting seats 130 are joined, and in the second state, the ends of the two first mounting seats 130 in each functional group protruding from the outer surface of the charging area 120 are flush. This structural setting is conducive to the stable placement of large-sized electronic devices in the functional group. Furthermore, in the first state, the edges of the two first mounting seats 130 adjacent to each other in sequence are joined and flush with the end away from the charging area 120, and this structural setting can enhance the appearance characteristics of the wireless charging stand 10.

[0068] 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.

[0069] 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.
