Detailed Description

To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1, fig. 2 and fig. 3, in an embodiment, an electronic device such as a smart phone, a smart watch, a smart band, a wireless headset with a wireless charging function can be placed in the wireless charging dock 10 for wireless charging. The wireless cradle 10 includes a cradle 100, a mounting stand 200, and a fan 300. In the embodiment of the present application, the base 100 has a substantially rectangular block shape, the mounting base 200 has a substantially rectangular block shape, and the mounting base 200 includes the coil module 210 and the charging region 220 covering the coil module 210. In a normal use state, the charging region 220 can be used to place an electronic device for wireless charging. Referring to fig. 4 and 5, the mounting base 200 can rotate relative to the base 100 to change an included angle between the charging region 220 and the base 100, and the charging region 220 can stand on the base 100. In the present embodiment, charging region 220 is part of the housing of mount 200. The fan 300 is disposed on the base 100 or the mounting base 200, and referring to fig. 6 and 7, when the charging area 220 is in a side-up state, the fan 300 can guide the external air to flow on a side of the charging area 220 away from the coil module 210 to exchange heat with the electronic device. In the present embodiment, the side-standing state is understood that the mount 200 may stand on the base 100 obliquely or vertically. Specifically, as shown in fig. 6, the thickness direction a1 of the base 100 and the thickness direction b1 of the mount 200 may be determined, and the side-up state is understood that the thickness direction a1 of the base 100 and the thickness direction b1 of the mount 200 may be disposed at an included angle, which may range from 10 degrees to 90 degrees, for example. In other embodiments, the cross-section of the mounting seat 200 may have other shapes, such as a major arc, a triangle, a polygon, etc., and the cross-section of the base seat 100 may also have other shapes, such as a racetrack shape, a rounded rectangle, a circle, etc. Wherein, the runway shape is a figure formed by connecting two semicircular arcs with two opposite sides of a rectangle respectively.

In some embodiments, the base 100 and the mounting base 200 are coupled by a damping hinge, such that the mounting base 200 can be positioned in multiple positions after being rotated at an angle relative to the base 100 to accommodate wireless charging requirements of electronic devices of different sizes. In other embodiments, the rotation axes of the base 100 and the mount 200 may be set to be positioned at certain specific positions, for example, when the thickness direction b1 of the mount 200 forms an angle of 10 degrees, 20 degrees, 30 degrees, 45 degrees or 60 degrees with the thickness direction of the base 100, the mount 200 may be reliably positioned at the base 100 to effectively support the electronic device to be charged. For example, a protrusion may be disposed on one of the mounting base 200 and the base 100, and a groove may be disposed on the other of the mounting base 200 and the base 100, and when the rotating shaft rotates to the specific position, the protrusion is received in the groove, so as to position the mounting base 200 at the specific position. Of course, it is understood that the number of the specific positions may be reduced or increased, for example, the mounting seat 200 may be stably positioned at two or more positions on the base 100.

In the present embodiment, with reference to fig. 8 and 9, the mounting base 200 may be in a flat state on the base 100, and the flat state may be understood as that the thickness direction b1 of the mounting base 200 is parallel to the thickness direction a1 of the base 100 or forms an acute angle of 10 degrees or less. For example, in some embodiments, when the base 100 is placed on a horizontal support surface, the thickness direction b1 of the mount 200 in a flat state is perpendicular to the horizontal support surface or at an acute angle of 80 degrees or more. In the flat state, the electronic device may be placed in the charging region 220 and supported by the mount 200, or the electronic device may be placed in the charging region 220 and supported by both the mount 200 and the cradle 100 for wireless charging. The flat-laid mount 200 can accommodate wireless charging requirements for electronic devices of various sizes. In the side-standing state, electronic devices with relatively large size, such as smart phones, tablet computers, and the like, may be supported by the mounting base 200 and the base 100 together, so that such electronic devices may be placed on the base 100 obliquely or vertically to facilitate the use of users while the electronic devices are wirelessly charged. For example, when the mount 200 is in a side-up state and wirelessly charges such electronic devices, the user can also conveniently watch movies or play games, etc., so that the convenience of use can be improved.

Further, in the embodiment of the present application, the mounting base 200 is provided with the mounting cavity 201, the coil module 210 is provided in the mounting cavity 201, and the air on the two opposite sides of the charging area 220 is isolated by the charging area 220. Specifically, in the present embodiment, charging region 220 is substantially in the form of a one-piece plate, and charging region 220 has no open structure in thickness direction b1 of mount 200. With the charging area 220 having such a structure, on one hand, water, an ash layer and the like can be prevented from easily entering the mounting base 200 from the charging area 220, so that the waterproof and dustproof performance of the mounting base 200 can be improved; on the other hand, in the wireless charging process of the electronic device, the structure of the charging area 220 can reduce the influence of the heat generated by the coil module 210 on the electronic device, and also reduce the influence of the heat generated by the electronic device on the coil module 210. It is understood that a side of mount 200 facing away from charging region 220, and a circumferential sidewall of mount 200 may be provided with heat dissipation vents.

Further, referring to fig. 8 and 9, the mounting base 200 may include a magnetism isolating sheet 230 disposed in the mounting cavity 201, the coil module 210 is stacked on the magnetism isolating sheet 230, and the magnetism isolating sheet 230 may be made of a ferrite wave-absorbing material, which has excellent magnetic conductivity, and can increase the magnetic flux of the coil module 210 and reduce the loss of the coil module 210, and can enable the magnetic induction lines to tightly surround the surrounding area with the magnetism isolating sheet 230 as the center to increase the electromagnetic induction strength, and improve the electromagnetic conversion efficiency. Of course, the magnetic shield 230 may be omitted.

Further, the wireless charging cradle 10 includes a circuit board 400 disposed in the cradle 100, and the circuit board 400 is electrically connected to the coil module 210 and the fan 300. The base 100 may be provided with an electrical connection interface, which is electrically connected to the circuit board 400, and the electrical connection interface is used to connect an external power source to supply power to the wireless charging cradle 10, so that the wireless charging cradle 10 can be used to charge the electronic device. The electric connection interface can be a USB interface, and can also be a cable with a plug, and the like. Of course, in other embodiments, the electrical connection interface may be located on the mount 200. Further, the cradle 200 or the cradle 100 may be provided with an indicator light for prompting the operating state of the wireless cradle 10. Of course, in other embodiments, the circuit board 400 may be disposed in the mounting base 200, or both the mounting base 200 and the base 100 are provided with the circuit board 400.

Further, referring to fig. 8 and 9, in an embodiment in which the fan 300 is disposed on the base 100 and the circuit board 400 is disposed on the base 100, the wireless charging stand 10 may include a heat insulation structure 500 disposed in the base 100, the heat insulation structure 500 may be connected to the base 100 and isolate the circuit board 400 from the fan 300, the heat insulation structure 500 may be made of plastic, silica gel, ceramic, glass fiber, asbestos, or the like, and has a low thermal conductivity, so that the influence of heat generated by the fan 300 on electronic components of the circuit board 400 during a wireless charging process can be reduced, and performance degradation or damage of the electronic components on the circuit board 400 due to an excessively high temperature can be prevented. The wireless charging cradle 10 can meet the requirement of high-power wireless charging, so as to shorten the wireless charging time. In some embodiments, the insulation structure 500 forms an insulation chamber 501 with the base 100, and the circuit board 400 is disposed in the insulation chamber 501 to isolate the circuit board 400 from the fan 300. Of course, in other embodiments, the insulation structure 500 may be plate-shaped or have other shapes.

In the embodiment in which the heat insulation structure 500 is provided to the base 100, one side of the circuit board 400 may be provided with a heat conductor capable of conducting heat generated from the circuit board 400 to the base 100. Specifically, in some embodiments, at least a part of the housing of the base 100 is made of a metal material, such as an aluminum alloy, a magnesium alloy, or stainless steel, and the heat conductor may be silicone grease or a metal heat conducting sheet, so as to conduct the heat generated by the circuit board 400 to the metal part of the base 100, and further dissipate the heat generated by the circuit board 400 to the air through the metal part of the base 100, so as to further improve the heat dissipation performance of the wireless charging stand 10.

Further, with reference to fig. 7 and 8, in some embodiments, when the charging region 220 is in a flat state or a side-standing state, the fan 300 can guide the external air to flow on a side of the charging region 220 away from the coil module 210. This arrangement facilitates heat dissipation of the electronic device and can improve the heat dissipation performance of the wireless charging stand 10. Further, in the embodiment of the present application, the fan 300 is a centrifugal fan 300, so as to facilitate the reduction of the overall thickness of the mounting base 200 or the base 100. For example, when the fan 300 is disposed on the base 100, the rotation axis of the fan 300 may extend along the thickness direction a1 of the base 100; when the fan 300 is disposed on the mounting base 200, the rotation axis of the fan 300 may extend in the thickness direction b1 of the mounting base 200.

Specifically, referring to fig. 3 and 4, in an embodiment, the mounting base 200 includes a connection portion 240 fixedly connected to the charging region 220, the connection portion 240 protrudes from one end of the charging region 220, and the connection portion 240 is rotatably connected to the base 100. The connecting portion 240 is provided with a first air duct 241, the base 100 is provided with a second air duct 101, the fan 300 is disposed in the base 100, and the fan 300 can guide the outside air to flow into the base 100 from one of the first air duct 241 and the second air duct 101 and guide the air to flow out from the other of the first air duct 241 and the second air duct 101, so that the air in the first air duct 241 can flow relatively with the air in the side of the charging area 220 away from the coil module 210. The pivotal connection of the link 240 to the base 100 may have a variety of configurations. For example, one of the connecting portion 240 and the base 100 may be provided with a rotating shaft, and the other may be provided with a shaft hole capable of rotatably matching with the rotating shaft, and the rotating shaft is received in the shaft hole to realize the rotatable matching of the mounting base 200 and the base 100. In other embodiments, the shaft may be a separate component, and the shaft is fixedly connected to one of the mounting base 200 and the base 100 and is rotatably engaged with the other. Of course, when the rotating shaft is an independent component, the mounting base 200 and the base 100 may be rotatably engaged with the rotating shaft, respectively.

In some embodiments, connecting portion 240 and charging region 220 are integrally formed and are part of a housing of mount 200, and in other embodiments, connecting portion 240 may be a separate component, e.g., connecting portion 240 may be made of a wear-resistant material to reduce wear of connecting portion 240 during rotation of mount 200. In the embodiment of the application, when the mounting base 200 rotates relative to the base 100 to change the included angle between the charging area 220 and the base 100, the first air duct 241 changes position along with the rotation of the charging area 220, but the first air duct 241 always faces the charging area 220, so that the fan 300 can guide the air flow on the side of the charging area 220 away from the coil module 210, and thus the heat of the electronic device is dissipated in the wireless charging process of the electronic device.

In conjunction with fig. 5 and 6, it can be understood that the fan 300 may include two ways to direct the air flow of the side of the charging region 220 facing away from the coil module 210. In one embodiment, the fan 300 is capable of guiding the external air to flow into the mounting base 200 from the first air duct 241 and guiding the air to flow out from the second air duct 101, so that the air in the space near the air charging region 220 in the mounting base 200 generates relative flow and exchanges heat with the electronic device. In another embodiment, the fan 300 can guide the external air to flow into the mounting seat 200 from the second air duct 101 and guide the air to flow from the first air duct 241 to the charging region 220, so that the air of the mounting seat 200 can flow opposite to the air of the space near the charging region 220 and exchange heat with the electronic device.

In some embodiments, when the mount 200 is in the flat state, the base 100 protrudes from the charging region 220 on the side of the charging region 220, that is, the base 100 may protrude from the mount 200 in the flat state in the thickness direction a1 of the base 100. In other embodiments, the charging area 220 facing away from the coil module 210 may be recessed, and have two opposite first edges 221 (refer to fig. 9) so that the charging area 220 has a structure with two sides being higher and a middle being lower, the fan 300 can guide the external air to flow between the two first edges 221, and when the mounting base 200 is in a flat state, the base 100 is flush with the first edges 221 at the side of the charging area 220. Here, the position of the first edge 221 is illustrated in fig. 9, but the position of the first edge 221 may be close to the middle of the charging region 220. In this embodiment, when the mounting base 200 is in a flat state and is used for wirelessly charging an electronic device with a relatively large size, the base 100 can also support the electronic device, so that the electronic device can be placed on the wireless charging base 10 more stably.

In the embodiment in which the charging area 220 is concave, for an electronic device such as a smartphone or a tablet computer with a wireless charging function and a slightly larger size, when the electronic device is placed in the charging area 220 for charging, the mounting base 200 may be in a flat state or a side-standing state, and the two opposite first edges 221 support the electronic device and form a channel for air flow between the electronic device and the charging area 220 by using the concave structure of the charging area 220. In the process of wirelessly charging the electronic device, the fan 300 may supply air from the first air duct 241, and after the air flow passes through the air flow channel and exchanges heat, the air flow flows out from the end of the charging area 220 far away from the first air duct 241, so as to improve the heat dissipation efficiency of the wireless charging stand 10.

For electronic devices with wireless charging function and slightly smaller size, such as smartwatches, wireless earphones, and the like, when the electronic device is placed in the charging area 220 for wireless charging, the mounting base 200 may be in a flat state, the electronic device may be placed in the concave structure of the charging area 220 and contact the outer surface of the charging area 220, the periphery of the electronic device and the first edge 221 may form a channel through which air flows, the fan 300 may be supplied with air by the first air duct 241, and the air flows through the periphery of the electronic device for heat exchange and is emitted into the air, which may also improve the heat dissipation efficiency of the wireless charging base 10. Of course, the fan 300 can draw air from the first air channel 241, and the description thereof is omitted.

Of course, in other embodiments, the charging area 220 may include a silicone pad or other structures, so that the charging area 220 can better support the electronic device, and can achieve a better heat insulation effect while preventing the electronic device from being scratched. The recessed structure of the charging region 220 may be formed by a silicone pad, or by the silicone pad and other structures of the charging region 220. Of course, the concave structure of the charging region 220 is not necessary, and for example, a side surface of the charging region 220 facing away from the coil module 210 may be planar.

Referring to fig. 10 and 11, in another embodiment, the mounting base 200 may include a supporting body 250, the supporting body 250 is rotatably connected to the base 100, and the positions of the charging region 220 and the coil module 210 are fixed relatively. The supporting body 250 can drive the charging region 220 to switch between a flat state and a side-standing state. Referring to fig. 10 and 11, the support 250 covers a part or all of the charging region 220 in a laid-flat state. Referring to fig. 12 and 13, the charging zone 220 can be telescopically moved with respect to the support 250 in the side-up state to change an exposed area of the charging zone 220. The support 250 and the cradle 100 support the electronic device together during the wireless charging process when the electronic device stands on the cradle 100.

Since the positions of the coil module 210 and the charging area 220 are fixed, when the mounting base 200 rotates relative to the base 100, the coil module 210 and the charging area 220 move synchronously. Referring to fig. 14 and 15, when the charging area 220 is in a side-standing state, the charging area 220 can move telescopically with respect to the supporting body 250 to adjust the position of the charging area 220. In the wireless charging stand 10 having such a structure, when the mounting stand 200 is in the side-up state, the position of the charging area 220 can be adjusted to be suitable for wireless charging of electronic devices of different sizes. For example, when the smartphone is being charged, the height of the coil module 210 from the horizontal support surface is relatively small; when the tablet computer is charged, the coil module 210 may be adjusted to a position higher than the horizontal supporting surface, so as to be suitable for wireless charging of the tablet computer. Of course, in some embodiments, when the smartphone is laid across, the height of the coil module 210 from the horizontal support surface is relatively small; when the smart mobile phone is placed vertically, the coil module 210 can be adjusted to a position higher than the horizontal supporting surface, so that the wireless charging requirement of the electronic equipment under various use scenes can be met. Of course, in some embodiments, when the mounting base 200 is in the flat state, the charging area 220 can also move telescopically relative to the supporting body 250 to adjust the position of the charging area 220, so as to be suitable for electronic devices with different sizes. In the flat state, the charging region 220 need not be exposed, for example, the charging region 220 may be entirely covered by the support 250.

In this embodiment, the connecting portion 240 is fixedly connected to the supporting body 250, the first air duct 241 is disposed on the connecting portion 240, and the second air duct 101 is disposed on the base 100. The fan 300 may be disposed in the base 100, and the fan 300 may guide the external air to flow into the base 100 from one of the first air channel 241 and the second air channel 101, and guide the air to flow out from the other of the first air channel 241 and the second air channel 101, so that the air in the first air channel 241 and the air in the side of the support 250 and the charging region 220 away from the coil module 210 can flow relatively. The structural arrangement of the first air duct 241, the second air duct 101 and the fan 300 may be similar to that of the foregoing embodiment, and will not be described herein again.

Further, in some embodiments, when the mount 200 is in the flat state, the base 100 may protrude from the supporting body 250 on a side of the supporting body 250 facing away from the coil module 210, that is, the base 100 may protrude from the mount 200 in the flat state in the thickness direction a1 of the base 100. In other embodiments, a side of the supporting body 250 facing away from the coil module 210 may have a concave structure, which has two opposite second edges 251 (refer to fig. 11) such that the supporting body 250 has a structure with two sides being higher and a middle being lower, the fan 300 can guide the external air to flow between the two second edges 251, and when the mounting seat 200 is in a flat state, the base 100 is flush with the second edges 251 on the side of the supporting body 250 facing away from the coil module 210. Wherein the position of the second edge 251 is illustrated in fig. 11, but the position of the second edge 251 may be closer to the middle of the supporting body 250. In this embodiment, when the mounting base 200 is in a flat state and is used for wirelessly charging an electronic device with a relatively large size, the base 100 can also support the electronic device, so that the electronic device can be placed on the wireless charging base 10 more stably.

In the embodiment in which the supporting body 250 is recessed, when an electronic device such as a smartphone or a tablet computer having a wireless charging function and a slightly larger size is placed in the charging area 220 for charging, the mounting base 200 may be in a flat state or a side-standing state, and the two opposite second edges 251 support the electronic device and form a channel for air flow between the electronic device and the supporting body 250 by using the recessed structure of the supporting body 250. In the process of wirelessly charging the electronic device, the fan 300 may supply air from the first air duct 241, and after the air flows through the air flow channel and exchanges heat, the air flows out from the end of the supporting body 250 far away from the first air duct 241, thereby improving the heat dissipation efficiency of the wireless charging stand 10. For the electronic device with a relatively large size and exposed to the charging area 220, due to the thickness of the supporting body 250, the supporting body 250 may have a certain gap between the side of the charging area 220 departing from the coil module 210 and the rear surface of the electronic device, thereby facilitating the flow of air and further facilitating the heat dissipation of the electronic device. Of course, the fan 300 can also draw air from the first air channel 241, and the description thereof is omitted.

For electronic devices with wireless charging function and slightly smaller size, such as smartwatches, wireless earphones, and the like, when the electronic device is placed in the charging area 220 for wireless charging, the mounting base 200 may be in a flat state, the electronic device may be placed at the concave structure of the supporting body 250 and contact the outer surface of the supporting body 250, the periphery of the electronic device and the second edge 251 may form a channel through which air flows, the fan 300 may be supplied with air by the first air duct 241, and the air flows through the periphery of the electronic device for heat exchange and is emitted into the air, which may also improve the heat dissipation efficiency of the wireless charging base 10.

Of course, in other embodiments, the supporting body 250 may include a structure such as a silicone pad, so that the supporting body 250 can better support the electronic device, and can achieve a better heat insulation effect while preventing the electronic device from being scratched. The concave structure of the supporting body 250 may be formed by a silicone pad, or by other structures of the silicone pad and the supporting body 250. Of course, the concave structure of the supporting body 250 is not necessary, and for example, a side surface of the supporting body 250 facing away from the coil module 210 may be planar.

Referring to fig. 16, 17 and 18, in other embodiments, the base 100 may be provided with a recessed area 103 and a boss 110, one end of the mounting base 200 close to the boss 110 may be capable of rotating relative to the base 100 to switch the mounting base 200 between a flat state and a side standing state, and the mounting base 200 is accommodated in the recessed area 103 in the flat state and the charging area 220 faces the side of the boss 110 in the side standing state. Specifically, in some embodiments, the mounting base 200 includes a moving member 260, the moving member 260 is rotatably connected to the base 100 and can drive the charging area 220 to switch between a flat state and a side standing state, and the charging area 220 can move relative to the moving member 260.

In some embodiments, boss 110 may protrude from charging region 220 when mount 200 is in a flat position. In other embodiments, a side of the charging region 220 facing away from the coil module 210 may also be recessed, that is, the charging region 220 has two opposite first edges 221, the fan 300 can guide the external air to flow between the two first edges 221, and when the mounting base 200 is in a flat state, the boss 110 is flush with the first edge 221 at the side of the charging region 220. The formation of the recessed structure of the charging region 220 and the function thereof can be referred to the foregoing embodiments, and are not described herein again. Of course, in some embodiments, the charging region 220 may be planar, and will not be described herein.

Referring to fig. 19 and 20, the moving member 260 may be plate-shaped or strip-shaped, the mounting base 200 may be provided with a guide groove 203 on a side away from the charging area 220, the moving member 260 is provided in the guide groove 203 and can move in the guide groove 203, and the guide groove 203 can guide and limit the movement of the moving member 260. In some embodiments, an end of the moving member 260 close to the boss 110 is rotatably connected to the bottom wall of the recessed area 103, and an end of the mounting base 200 close to the boss 110 may be closer to a side surface of the boss 110 in the flat state. For example, in some embodiments, when the mount 200 is in a flat position, an end of the mount 200 near the boss 110 abuts a side of the boss 110. This arrangement can provide the wireless cradle 10 in a flat position with good appearance characteristics. When the mounting base 200 rotates relative to the base 100 to switch to the side-standing state, the moving member 260 rotates relative to the base 100, and the charging region 220 moves relative to the moving member 260, so that a space for the charging region 220 to move obliquely can be formed between the end of the moving member 260 and the side surface of the boss 110, thereby preventing the boss 110 from interfering with the charging region 220. In the wireless charging stand 10 with such a structure, the charging area 220 and the base 100 can form a plurality of included angles, and the coil module 210 can move along with the charging area 220 to adjust the position of the coil module 210, so as to adapt to the wireless charging requirements of electronic devices with different sizes, and also meet the wireless charging requirements of the same electronic device in different postures (such as horizontal and vertical).

Of course, in some embodiments, a relatively large distance may be disposed between the moving element 260 and the sidewall of the boss 110, so that when the mounting base 200 stands on the base 100, an interval may be formed between the charging region 220 and a side of the boss 110 facing the charging region 220, so that when an electronic device such as a smart phone or a tablet computer is placed on the mounting base 200 for wireless charging, an end of the electronic device may be accommodated in the interval, and thus the electronic device may be smoothly placed on the wireless charging stand 10.

Further, referring to fig. 21 and 22, in some embodiments, the mounting base 200 includes a protrusion 270, the protrusion 270 is connected to the charging region 220 and protrudes from a side of the charging region 220 facing away from the coil module 210, and the charging region 220 is located between the protrusion 270 and the boss 110 in the flat state. The fan 300 is disposed in the protrusion 270, that is, the fan 300 is disposed on the mounting base 200. Referring to fig. 23, 24 and 25, the protrusion 270 is provided with a third air channel 271 and a fourth air channel 273, the opening of the fourth air channel 273 faces the charging region 220, and the fan 300 can guide the external air to flow into the protrusion 270 from one of the third air channel 271 and the fourth air channel 273 and guide the air to flow out from the other of the third air channel 271 and the fourth air channel 273, so that the air in the fourth air channel 273 can exchange heat with the air at the side of the charging region 220 away from the coil module 210.

In this embodiment, for an electronic device such as a smartphone or a tablet pc having a wireless charging function and a slightly larger size, when the electronic device is placed in the charging area 220 for charging, the mounting base 200 may be in a flat state or a side-standing state. During the wireless charging process of the electronic device, the fan 300 can guide the air in the protrusion 270 and the air in the space near the charging area 220 to generate a relative flow and exchange heat with the electronic device, so as to improve the heat dissipation efficiency of the wireless charging stand 10. For an electronic device with a wireless charging function and a slightly smaller size, such as a smart watch, a wireless headset, etc., when the electronic device is placed in the charging area 220 for wireless charging, the mounting base 200 can be in a flat state, and the fan 300 can guide the air in the protruding portion 270 and the air in the space near the charging area 220 to generate relative flow and exchange heat with the electronic device, so as to improve the heat dissipation efficiency of the wireless charging base 10. It is understood that the fan 300 can guide the external air to flow into the protrusion 270 from the fourth wind channel 273 and flow out of the protrusion 270 from the third wind channel 271, and the fan 300 can also guide the external air to flow into the protrusion 270 from the third wind channel 271 and flow out from the fourth wind channel 273, which will not be described herein.

Referring to fig. 26, 27, and 28, in other embodiments, the fan 300 may be disposed within the boss 110. Referring to fig. 29, the boss 110 is provided with a fifth air duct 111 and a sixth air duct 113, and the opening of the sixth air duct 113 is close to the charging area 220. Referring to fig. 30, 31, 32, and 33, in the side-standing state, the fan 300 can guide the external air to flow into the boss 110 from one of the fifth air passage 111 and the sixth air passage 113 and guide the air to flow out from the other of the fifth air passage 111 and the sixth air passage 113, so that the air of the sixth air passage 113 can exchange heat with the air of the side of the charging region 220 away from the coil module 210. Further, referring to fig. 34 and 35, in this embodiment, the opening of the sixth air duct 113 may be closed by the mount 200 when the mount 200 is in the flat state, that is, the fan 300 may not be operated when the mount 200 is in the flat state. Of course, other air duct structures may be provided, so that the fan 300 can guide the air in the boss 110 to generate a relative flow with the air at the side of the charging area 220 away from the coil module 210, so as to facilitate heat dissipation of the electronic device. In this embodiment, when the mounting base 200 is in a flat state, the charging area 220 of the mounting base 200 can be flush with the base 100, so that the wireless charging stand 10 has good appearance. Certainly, when the mounting base 200 is in a flat state, the boss 110 may also protrude the charging area 220, so as to facilitate the design of the sixth air duct 113, and facilitate the fan 300 to guide the air in the boss 110 and the air in the charging area 220 on the side away from the coil module 210 to generate relative flow, thereby facilitating the heat dissipation of the electronic device.

Further, in some embodiments, the mounting base 200 may be provided with an airflow channel, so that the fan 300 can guide the air in the mounting cavity 201 to flow relative to the external air and perform heat exchange when the mounting base 200 is in a flat state or a side standing state. With such a structure, the fan 300 can guide the air flow of the side of the charging area 220 away from the coil module 210 to dissipate heat of the electronic device, and can also guide the air flow of the side of the charging area 220 facing the coil module 210 to dissipate heat of the coil module 210, and because the air flow of the two opposite sides of the charging area 220 can be isolated to reduce mutual influence between heat generation of the electronic device and heat generation of the coil module 210, the heat dissipation efficiency of the wireless charging stand 10 and the electronic device can be improved.

Above wireless charging seat 10, because mount pad 200 can rotate relative to base 100 in order to change the contained angle between charging district 220 and the base 100, and make charging district 220 can stand on one's side in base 100, electronic equipment such as the smart mobile phone that possesses the wireless function of charging, intelligent wrist-watch, wireless earphone all can place in charging district 220 and carry out wireless charging, wireless charging seat 10 can the multiple model of adaptation, has promoted the convenience of using. Because the fan 300 can guide the outside air to flow at the side of the charging area 220 away from the coil module 210 in the side-standing state, the fan 300 can promote the air at the periphery of the electronic device to flow in the wireless charging process of the electronic device, so as to facilitate the heat dissipation of the electronic device. The heat dissipation air duct of the wireless charging stand 10 is easy to design, has a better heat dissipation effect, and can meet the requirement of high-power wireless charging so as to shorten the wireless charging time.
