Description
Technical Field
[0001] The present application relates to the technical field of charging bases. Background Art
[0002] Wireless charging stations can be used to charge electronic devices such as mobile terminals. They can be divided into two categories: vertical wireless charging stations and horizontal wireless charging stations. For vertical wireless charging stations, electronic devices are generally placed on the wireless charging station at an angle when charging. Since the coil position of the wireless charging station is relatively fixed, the models that can be adapted to the vertical wireless charging station are relatively limited.

[0062] 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.
[0063] refer to Figure 1 , Figure 2 and Figure 3 In one embodiment, electronic devices such as smart phones, smart watches, smart bracelets, wireless headphones, etc. with wireless charging functions can be placed on the wireless charging stand 10 for wireless charging. The wireless charging stand 10 includes a base 100, a mounting stand 200 and a fan 300. In the embodiment of the present application, the base 100 is roughly rectangular, the mounting stand 200 is roughly rectangular, and the mounting stand 200 includes a coil module 210 and a charging area 220 covering the coil module 210. In normal use, the charging area 220 can be used to place electronic devices for wireless charging. Combined with Figure 4 and Figure 5 The mounting base 200 can rotate relative to the base 100 to change the angle between the charging area 220 and the base 100, and enable the charging area 220 to stand sideways on the base 100. In the embodiment of the present application, the charging area 220 is a part of the housing of the mounting base 200. The fan 300 is provided on the base 100 or the mounting base 200, and at the same time, Figure 6 and Figure 7 When the charging area 220 is in the side-standing state, the fan 300 can guide the outside air to flow on the side of the charging area 220 away from the coil module 210 to exchange heat with the electronic device. In the embodiment of the present application, the side-standing state should be understood as the mounting base 200 can be tilted or vertically standing on the base 100. Specifically, as Figure 6 As shown, the thickness direction a1 of the base 100 and the thickness direction b1 of the mounting seat 200 can be determined. The side-standing state should be understood as the thickness direction a1 of the base 100 and the thickness direction b1 of the mounting seat 200 can be set at an angle. For example, the range of the angle can be 10 degrees to 90 degrees. In other embodiments, the cross-section of the mounting seat 200 can be in other shapes such as a major arc, a triangle or a polygon, and the cross-section of the base 100 can also be in other shapes such as a runway shape, a rounded rectangle, a circle, etc. Among them, the runway shape refers to a figure formed by two semicircular arcs connected to the opposite sides of a rectangle.
[0064] In some embodiments, the base 100 and the mounting base 200 are connected by a damping shaft so that the mounting base 200 can be positioned at multiple positions after rotating a certain angle relative to the base 100 to meet the wireless charging requirements of electronic devices of different sizes. In other embodiments, the rotating shafts of the base 100 and the mounting base 200 can be set to achieve positioning at certain specific positions. For example, when the angle between the thickness direction b1 of the mounting base 200 and the thickness direction of the base 100 is 10 degrees, 20 degrees, 30 degrees, 45 degrees or 60 degrees, the mounting base 200 can be reliably positioned on the base 100 to effectively support the electronic device to be charged. For example, a protrusion can be set on one of the mounting base 200 and the base 100, and a groove can be set on the other of the mounting base 200 and the base 100. When the rotating shaft rotates to the above-mentioned specific position, the protrusion is accommodated in the groove, thereby realizing the positioning of the mounting base 200 at a specific position. Of course, it is understandable that the number of the above-mentioned specific positions can be reduced or increased. For example, the mounting seat 200 can be stably positioned at two positions on the base 100, or can be stably positioned at more than two positions.
[0065] Combination Figure 8 and Fig. 9 In the embodiment of the present application, the mounting seat 200 can also be in a flat state on the base 100. The flat state can be understood as the thickness direction b1 of the mounting seat 200 is parallel to the thickness direction a1 of the base 100 or is at an acute angle of less than 10 degrees. For example, in some embodiments, when the base 100 is placed on a horizontal support surface, the thickness direction b1 of the mounting seat 200 in the flat state is perpendicular to the horizontal support surface or is at an acute angle of more than 80 degrees. In the flat state, the electronic device can be placed in the charging area 220 and supported by the mounting seat 200, or the electronic device can be placed in the charging area 220 and supported by the mounting seat 200 and the base 100 for wireless charging. The mounting seat 200 in the flat state can meet the wireless charging requirements of electronic devices of various sizes. In the side-standing state, relatively large electronic devices such as smart phones, tablet computers, etc. can be supported by the mounting seat 200 and the base 100, so that such electronic devices can be placed on the base 100 obliquely or vertically to facilitate user use while the electronic device is wirelessly charged. For example, when the mounting base 200 is in a side-standing state and wirelessly charges such electronic devices, users can also conveniently watch movies or play games, etc., thereby improving the convenience of use.
[0066] Further, in the embodiment of the present application, the mounting seat 200 is provided with a mounting cavity 201, the coil module 210 is provided in the mounting cavity 201, and the air on the opposite sides of the charging area 220 is isolated by the charging area 220. Specifically, in the embodiment of the present application, the charging area 220 is roughly in the shape of a whole plate, and the charging area 220 has no opening structure in the thickness direction b1 of the mounting seat 200. The charging area 220 with such a structure can, on the one hand, prevent water, dust layers, etc. from easily entering the mounting seat 200 from the charging area 220, thereby improving the waterproof and dustproof performance of the mounting seat 200; on the other hand, during the process of wireless charging 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 can also reduce the influence of the heat generated by the electronic device on the coil module 210. It can be understood that the side of the mounting seat 200 away from the charging area 220 and the circumferential side wall of the mounting seat 200 can be provided with heat dissipation holes.
[0067] Further, refer to Figure 8 and Fig. 9 The mounting base 200 may include a magnetic isolation sheet 230 disposed in the mounting cavity 201, and the coil module 210 is stacked on the magnetic isolation sheet 230. The magnetic isolation sheet 230 may be made of ferrite wave absorbing material, which has excellent magnetic conductivity, can increase the magnetic flux of the coil module 210 and reduce the loss of the coil module 210, and can make the magnetic flux lines tightly surround the surrounding area centered on the magnetic isolation sheet 230 to increase the electromagnetic induction intensity and improve the electromagnetic conversion efficiency. Of course, the magnetic isolation sheet 230 can be omitted.
[0068] Further, the wireless charging stand 10 includes a circuit board 400 disposed in the base 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 supply to power the wireless charging stand 10, so that the wireless charging stand 10 can be used to charge electronic devices. The electrical connection interface can be a USB interface, or a cable with a plug, etc. Of course, in other embodiments, the electrical connection interface can also be located in the mounting stand 200. Further, the mounting stand 200 or the base 100 can be provided with an indicator light to indicate the working status of the wireless charging stand 10. Of course, in other embodiments, the circuit board 400 can be disposed in the mounting stand 200, or both the mounting stand 200 and the base 100 are provided with a circuit board 400.
[0069] Further, refer to Figure 8 and Fig. 9In the embodiment where 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, and the heat insulation structure 500 may be made of plastic, silicone, ceramic, glass fiber, asbestos, etc., and its thermal conductivity is low, so that the heat generated by the fan 300 during wireless charging can reduce the influence of the electronic components of the circuit board 400, so as to prevent the electronic components on the circuit board 400 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 500 and the base 100 form a heat insulation cavity 501, and the circuit board 400 is disposed in the heat insulation cavity 501 to isolate the circuit board 400 from the fan 300. Of course, in other embodiments, the heat insulation structure 500 may also be in the shape of a plate or other shapes.
[0070] In the embodiment where the base 100 is provided with the heat insulation structure 500, a heat conductor may be provided on one side of the circuit board 400, and the heat conductor can conduct the heat generated by the circuit board 400 to the base 100. Specifically, in some embodiments, at least a portion of the outer shell 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 a silicone grease or a metal heat conductive sheet, so as to conduct the heat generated by the circuit board 400 to the metal part of the base 100, and then dissipate the heat generated by the circuit board 400 into 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.
[0071] Further, combined with Figure 7 and Figure 8 In some embodiments, when the charging area 220 is in a flat state or a sideways state, the fan 300 can guide the outside air to flow on the side of the charging area 220 away from the coil module 210. This arrangement is beneficial to the heat dissipation of electronic equipment and can improve the heat dissipation performance of the wireless charging stand 10. Further, in an embodiment of the present application, the fan 300 is a centrifugal fan 300, which is beneficial to the thinning of the overall thickness of the mounting seat 200 or the base 100. For example, when the fan 300 is arranged on the base 100, the rotating shaft of the fan 300 can extend along the thickness direction a1 of the base 100; when the fan 300 is arranged on the mounting seat 200, the rotating shaft of the fan 300 can extend along the thickness direction b1 of the mounting seat 200.
[0072] Specifically, refer to Figure 3 and Figure 4In one embodiment, the mounting base 200 includes a connecting portion 240 fixedly connected to the charging area 220, the connecting portion 240 protrudes from one end of the charging area 220, and the connecting 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, and the fan 300 is provided 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 generate relative flow with the air on the side of the charging area 220 away from the coil module 210. The rotatable connection between the connecting portion 240 and the base 100 can have a variety of structural forms. For example, one of the connection portion 240 and the base 100 may be provided with a rotating shaft, and the other may be provided with an axial hole capable of rotating with the rotating shaft, and the rotating shaft is accommodated in the axial hole to realize the rotational cooperation between the mounting seat 200 and the base 100. In other embodiments, the rotating shaft may be an independent part, and the rotating shaft is fixedly connected to one of the mounting seat 200 and the base 100, and rotates with the other. Of course, when the rotating shaft is an independent part, the mounting seat 200 and the base 100 can respectively rotate with the rotating shaft.
[0073] In some embodiments, the connection portion 240 and the charging area 220 are integrally formed and are part of the housing of the mounting base 200. In other embodiments, the connection portion 240 may be an independent component. For example, the connection portion 240 may be made of wear-resistant material to reduce the wear of the connection portion 240 during the rotation of the mounting base 200. In the embodiment of the present application, when the mounting base 200 rotates relative to the base 100 to change the angle between the charging area 220 and the base 100, the first air duct 241 changes position as the charging area 220 rotates, 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 to dissipate heat for the electronic device during wireless charging of the electronic device.
[0074] Combination Figure 5 and Figure 6It can be understood that the fan 300 can guide the air flow on the side of the charging area 220 away from the coil module 210 in two ways. In one embodiment, the fan 300 can guide the outside air to flow into the mounting base 200 from the first air duct 241, and guide the air to flow out from the second air duct 101, so that the air in the space near the air charging area 220 in the mounting base 200 can generate relative flow and perform heat exchange with the electronic device. In another embodiment, the fan 300 can guide the outside air to flow into the mounting base 200 from the second air duct 101, and guide the air to flow from the first air duct 241 to the charging area 220, so that the air in the mounting base 200 can generate relative flow with the air in the space near the charging area 220 and perform heat exchange with the electronic device.
[0075] In some embodiments, when the mounting base 200 is in a flat state, the base 100 protrudes from the charging area 220 on the side where the charging area 220 is located, that is, in the thickness direction a1 of the base 100, the base 100 can protrude from the mounting base 200 in the flat state. In other embodiments, the charging area 220 away from the coil module 210 can be concave, having two opposite first edges 221 (refer to Fig. 9 ) so that the charging area 220 is slightly higher on both sides and slightly lower in the middle, the fan 300 can guide the outside air to flow between the two first edges 221, and when the mounting base 200 is in a flat state, on the side where the charging area 220 is located, the base 100 is flush with the first edge 221. Among them, the position of the first edge 221 is shown in Fig. 9 However, the first edge 221 may be located closer to the middle of the charging area 220. In this embodiment, when the mounting base 200 is in a flat state and is used to wirelessly charge a relatively large electronic device, the base 100 may also support the electronic device so that the electronic device can be placed on the wireless charging base 10 more stably.
[0076] In the embodiment where the charging area 220 is concave, for electronic devices such as smart phones and tablet computers with wireless charging functions and slightly larger in size, when the electronic device is placed in the charging area 220 for charging, the mounting base 200 can be in a flat state or a sideways state, and the two opposite first edges 221 support the electronic device and use the concave structure of the charging area 220 to form a channel for airflow between the electronic device and the charging area 220. During the process of wireless charging of the electronic device, the fan 300 can supply air from the first air duct 241, and the airflow flows through the above-mentioned airflow channel and performs heat exchange, and then flows out from the end of the charging area 220 away from the first air duct 241, thereby improving the heat dissipation efficiency of the wireless charging base 10.
[0077] 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 220 for wireless charging, the mounting base 200 can be in a flat state, and the electronic device can 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 can form a channel for airflow, and the fan 300 can send air through the first air duct 241. The airflow flows through the periphery of the electronic device for heat exchange and dissipates into the air. This method can also improve the heat dissipation efficiency of the wireless charging stand 10. Of course, the fan 300 can draw air from the first air duct 241, which will not be repeated here.
[0078] Of course, in other embodiments, the charging area 220 may include structures such as a silicone pad, so that the charging area 220 can better support the electronic device, and can also provide a good heat insulation effect while preventing the electronic device from being scratched. The concave structure of the charging area 220 can be formed by a silicone pad, or by a silicone pad and other structures of the charging area 220. Of course, the concave structure of the charging area 220 is not necessary. For example, the surface of the side of the charging area 220 that is away from the coil module 210 can be flat.
[0079] refer to Fig.10 and Fig.11 In another embodiment, the mounting base 200 may include a support body 250, which is rotatably connected to the base 100, and the charging area 220 and the coil module 210 are relatively fixed. The support body 250 can drive the charging area 220 to switch between a flat state and a sideways state. Fig.10 and Fig.11 When in a flat state, the support body 250 covers part or all of the charging area 220. Fig.12 and Fig.13 In the side-standing state, the charging area 220 can be telescopically moved relative to the support body 250 to change the exposed area of the charging area 220. When the electronic device is side-standing on the base 100 for wireless charging, the support body 250 and the base 100 jointly support the electronic device.
[0080] Since the positions of the coil module 210 and the charging area 220 are relatively fixed, when the mounting base 200 rotates relative to the base 100, the coil module 210 and the charging area 220 move synchronously. Fig.14 and Fig.15, when the charging area 220 is in the side-standing state, the charging area 220 can be telescopically moved relative to the support body 250 to adjust the position of the charging area 220. For the wireless charging stand 10 of this structure, when the mounting stand 200 is in the side-standing 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 a smartphone is charged, the height of the coil module 210 from the horizontal support surface is relatively small; when a tablet computer is charged, the coil module 210 can be adjusted to a position higher than the horizontal support surface to be suitable for wireless charging of the tablet computer. Of course, in some embodiments, when the smartphone is placed horizontally, the height of the coil module 210 from the horizontal support surface is relatively small; when the smartphone is placed vertically, the coil module 210 can be adjusted to a position higher than the horizontal support surface, thereby meeting the wireless charging requirements of electronic devices in various usage scenarios. Of course, in some embodiments, when the mounting stand 200 is in the flat state, the charging area 220 can also be telescopically moved relative to the support body 250 to adjust the position of the charging area 220, thereby being suitable for electronic devices of different sizes. In the flat state, the charging area 220 does not need to be exposed, for example, the charging area 220 can be completely covered by the support body 250 .
[0081] In this embodiment, the connection portion 240 is fixedly connected to the support body 250, the first air duct 241 is provided at the connection portion 240, and the second air duct 101 is provided at the base 100. The fan 300 may be provided in the base 100, and the fan 300 may 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 generate relative flow with the air on the side of the support body 250 and the charging area 220 away from the coil module 210. The structural arrangement of the first air duct 241, the second air duct 101 and the fan 300 may be similar to the aforementioned embodiment, and will not be repeated here.
[0082] Further, in some embodiments, when the mounting base 200 is in a flat state, the base 100 may protrude from the supporting body 250 on the side of the supporting body 250 away from the coil module 210, that is, in the thickness direction a1 of the base 100, the base 100 may protrude from the mounting base 200 in a flat state. In other embodiments, the side of the supporting body 250 away from the coil module 210 may be a concave structure having two opposite second edges 251 (refer to Fig.11 ) so that the support body 250 has a structure that is slightly higher at both sides and slightly lower in the middle, and the fan 300 can guide the outside air to flow between the two second edges 251, and when the mounting base 200 is in a flat state, on the side of the support body 250 away from the coil module 210, the base 100 is flush with the second edge 251. Among them, the position of the second edge 251 is shown in Fig.11However, the position of the second edge 251 can be close to the middle of the support body 250. In this embodiment, when the mounting base 200 is in a flat state and is used to wirelessly charge a relatively large electronic device, 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.
[0083] In the embodiment where the support body 250 is concave, for electronic devices such as smart phones and tablet computers with wireless charging functions and slightly larger sizes, when the electronic devices are placed in the charging area 220 for charging, the mounting seat 200 can be in a flat state or a sideways state, and the two opposite second edges 251 support the electronic devices and use the concave structure of the support body 250 to form a channel for airflow between the electronic devices and the support body 250. During the process of wireless charging of the electronic devices, the fan 300 can supply air from the first air duct 241, and the airflow flows through the above-mentioned airflow channel and performs heat exchange, and then flows out from the end of the support body 250 away from the first air duct 241, thereby improving the heat dissipation efficiency of the wireless charging stand 10. For electronic devices with relatively large sizes and requiring the charging area 220 to be exposed, due to the thickness of the support body 250, the support body 250 can make a certain gap between the side of the charging area 220 away from the coil module 210 and the rear surface of the electronic device, thereby facilitating the flow of air and facilitating the heat dissipation of the electronic device. Of course, the fan 300 can also draw air from the first air duct 241, which will not be described in detail here.
[0084] 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 220 for wireless charging, the mounting seat 200 can be in a flat state, and the electronic device can be placed in the recessed structure of the support body 250 and contact the outer surface of the support body 250. The periphery of the electronic device and the second edge 251 can form a channel for air flow, and the fan 300 can supply air through the first air duct 241. The air flow flows through the periphery of the electronic device for heat exchange and dissipates into the air. This method can also improve the heat dissipation efficiency of the wireless charging stand 10.
[0085] Of course, in other embodiments, the support body 250 may include structures such as a silicone pad, so that the support body 250 can better support the electronic device, and can also provide a good heat insulation effect while preventing the electronic device from being scratched. The concave structure of the support body 250 can be formed by a silicone pad, or by a silicone pad and other structures of the support body 250. Of course, the concave structure of the support body 250 is not necessary. For example, the surface of one side of the support body 250 that is away from the coil module 210 can be flat.
[0086] refer to Fig.16 , Fig.17 and Fig.18In other embodiments, the base 100 may be provided with a recessed area 103 and a boss 110, and one end of the mounting seat 200 close to the boss 110 can rotate relative to the base 100 so that the mounting seat 200 can switch between the flat state and the side-standing state, and the mounting seat 200 is accommodated in the recessed area 103 when in the flat state, and the charging area 220 faces the side where the boss 110 is located when in the side-standing state. Specifically, in some embodiments, the mounting seat 200 includes a moving member 260, which is rotatably connected to the base 100 and can drive the charging area 220 to switch between the flat state and the side-standing state, and the charging area 220 can move relative to the moving member 260.
[0087] In some embodiments, the boss 110 may protrude from the charging area 220 when the mounting base 200 is in a flat state. In other embodiments, the side of the charging area 220 that is away from the coil module 210 may also be a concave structure, that is, the charging area 220 has two opposite first edges 221, and the fan 300 can guide the outside air to flow between the two first edges 221, and when the mounting base 200 is in a flat state, on the side where the charging area 220 is located, the boss 110 is flush with the first edge 221. The formation of the concave structure of the charging area 220 and its function can refer to the aforementioned embodiment, which will not be repeated here. Of course, in some embodiments, the charging area 220 can be planar, which will not be repeated here.
[0088] refer to Fig.19 and Fig. 20The movable member 260 may be in the shape of a plate or a strip. The mounting base 200 may be provided with a guide groove 203 on the side facing away from the charging area 220. The movable member 260 is disposed in the guide groove 203 and can move in the guide groove 203. The guide groove 203 may guide and limit the movement of the movable member 260. In some embodiments, one end of the movable member 260 close to the boss 110 is rotatably connected to the bottom wall of the recessed area 103, and one end of the mounting base 200 close to the boss 110 may be relatively close to the side of the boss 110 when in a flat state. For example, in some embodiments, when the mounting base 200 is in a flat state, one end of the mounting base 200 close to the boss 110 fits the side of the boss 110. This arrangement can make the wireless charging base 10 in a flat state have better 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 area 220 moves relative to the moving member 260 so that a space for the charging area 220 to move obliquely can be formed between the end of the moving member 260 and the side of the boss 110, thereby preventing the boss 110 from interfering with the charging area 220. In the wireless charging base 10 of this structure, the charging area 220 and the base 100 can form a variety of angles, and the coil module 210 can move with the charging area 220 to adjust the position of the coil module 210, thereby adapting to the wireless charging requirements of electronic devices of different sizes, and also meeting the wireless charging requirements of the same electronic device in different postures (e.g., horizontal or vertical).
[0089] Of course, in some embodiments, a relatively large distance can be set between the moving member 260 and the side wall of the boss 110, so that when the mounting seat 200 is placed on the side of the base 100, a gap can be formed between the charging area 220 and the side of the boss 110 facing the charging area 220, so that when electronic devices such as smart phones and tablet computers are placed on the mounting seat 200 for wireless charging, the end of the electronic device can be accommodated in the gap, thereby allowing the electronic device to be stably placed on the wireless charging seat 10.
[0090] Further, refer to Fig.21 and Fig. 22 In some embodiments, the mounting base 200 includes a protrusion 270, which is connected to the charging area 220 and protrudes from the side of the charging area 220 away from the coil module 210. When the charging area 220 is in a flat state, it is located between the protrusion 270 and the boss 110. The fan 300 is disposed in the protrusion 270, that is, the fan 300 is disposed in the mounting base 200. Also refer to Fig.23 , Fig.24 and Fig.25The raised portion 270 is provided with a third air duct 271 and a fourth air duct 273, and the opening of the fourth air duct 273 faces the charging area 220. The fan 300 can guide the outside air to flow into the raised portion 270 from one of the third air duct 271 and the fourth air duct 273, and guide the air to flow out from the other of the third air duct 271 and the fourth air duct 273, so that the air in the fourth air duct 273 can perform heat exchange with the air on the side of the charging area 220 away from the coil module 210.
[0091] In this embodiment, 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 220 for charging, the mounting seat 200 can be in a flat state or a sideways state. During the process of wireless charging of the electronic device, the fan 300 can guide the air in the raised portion 270 to flow relative to the air in the space near the charging area 220 and perform heat exchange with the electronic device to improve the heat dissipation efficiency of the wireless charging seat 10. For electronic devices such as smart watches and wireless headphones that have a wireless charging function and are slightly smaller in size, when the electronic device is placed in the charging area 220 for wireless charging, the mounting seat 200 can be in a flat state, and the fan 300 can guide the air in the raised portion 270 to flow relative to the air in the space near the charging area 220 and perform heat exchange with the electronic device to improve the heat dissipation efficiency of the wireless charging seat 10. It is understandable that the fan 300 can guide the outside air to flow into the protrusion 270 from the fourth air duct 273 and flow out of the protrusion 270 from the third air duct 271. The fan 300 can also guide the outside air to flow into the protrusion 270 from the third air duct 271 and flow out of the protrusion 270 from the fourth air duct 273, which will not be repeated here.
[0092] refer to Fig.26 , Fig. 27 and Fig.28 In other embodiments, the fan 300 may be disposed in the boss 110. 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. Fig.30 , Fig.31 , Fig.32 and Fig.33 In the side-standing state, the fan 300 can guide the outside air to flow into the boss 110 from one of the fifth air duct 111 and the sixth air duct 113, and guide the air to flow out from the other of the fifth air duct 111 and the sixth air duct 113, so that the air in the sixth air duct 113 can exchange heat with the air on the side of the charging area 220 away from the coil module 210. Further, refer to Fig.34 and Fig.35In this embodiment, when the mounting base 200 is in a flat state, the opening of the sixth air duct 113 can be closed by the mounting base 200, that is, the fan 300 can not work in the flat state. Of course, other air duct structures can also be set so that the fan 300 can guide the air in the boss 110 and the air on the side of the charging area 220 away from the coil module 210 to produce relative flow, so as to facilitate the heat dissipation of the electronic device. In this embodiment, when the mounting base 200 is in a flat state, the side of the mounting base 200 where the charging area 220 is located can be flush with the base 100, so that the wireless charging base 10 has better appearance characteristics. Of course, when the mounting base 200 is in a flat state, the boss 110 can also protrude from 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 on the side of the charging area 220 away from the coil module 210 to produce relative flow, thereby facilitating the heat dissipation of the electronic device.
[0093] Furthermore, in some embodiments, the mounting base 200 may be provided with an air flow channel so that when the mounting base 200 is in a flat state or a sideways state, the fan 300 can guide the air in the mounting cavity 201 to flow relative to the outside air and exchange heat. With this structural arrangement, the fan 300 can not only guide the air flow on the side of the charging area 220 away from the coil module 210 to facilitate the heat dissipation of the electronic device, but also guide the air flow on the side of the charging area 220 toward the coil module 210 to facilitate the heat dissipation of the coil module 210. Moreover, since the charging area 220 can isolate the air on the opposite sides to reduce the mutual influence between the heat generation of the electronic device and the heat generation of the coil module 210, the heat dissipation efficiency of the wireless charging base 10 and the electronic device can be improved.
[0094] In the above wireless charging stand 10, since the mounting seat 200 can rotate relative to the base 100 to change the angle between the charging area 220 and the base 100, and the charging area 220 can stand sideways on the base 100, electronic devices such as smart phones, smart watches, wireless headphones, etc. with wireless charging functions can be placed in the charging area 220 for wireless charging. The wireless charging stand 10 can be adapted to a variety of models, which improves the convenience of use. Since the fan 300 can guide the outside air to flow on the side of the charging area 220 away from the coil module 210 when in the side-standing state, during the process of wireless charging of the electronic device, the fan 300 can cause the air around the electronic device to flow, so as to facilitate the heat dissipation of the electronic device. The heat dissipation duct of the above 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.
[0095] 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.
[0096] 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.
