DETAILED DESCRIPTION
[0050] 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.
[0051] refer to Figure 1 and Figure 2The present application discloses a wireless charging stand 10, which can be used to wirelessly charge electronic devices such as smart phones, tablet computers, wireless headphones, smart watches, etc. with wireless charging functions. Figure 3 and Figure 4 The wireless charging stand 10 includes a body 11 and a support member 12 connected to the body 11, the support member 12 is used to support the body 11 and the support member 12 includes a support plate 121 and a bracket 123. In some embodiments, the body 11 is roughly rectangular, and the support plate 121 is rectangular and similar in shape to the body 11. In other embodiments, the body 11 may also be other shapes such as a circular or elliptical block, and the support plate 121 may be similar in shape to the body 11, or the support plate 121 may be different from the body 11. For example, the body 11 may be elliptical, and the support plate 121 may be runway-shaped. The runway shape refers to a figure formed by two short sides of a rectangle being connected to a semicircular arc.
[0052] The support plate 121 includes a first end 121a and a second end 121b that are arranged opposite to each other in a first direction. Specifically, in an embodiment in which the support plate 121 is in the shape of a rectangular plate, the first end 121a and the second end 121b correspond to the two ends in the length direction of the rectangle. In embodiments in which the support plate 121 is in other shapes, the first direction can be manually specified to be used as a reference direction to determine the positions of the first end 121a and the second end 121b. Further, in some embodiments, a silicone pad or a silicone column or other structure can be provided on the side of the support plate 121 facing away from the body 11 to support the wireless charging stand 10 when the wireless charging stand 10 is placed on a support object such as a desktop.
[0053] The body 11 includes a housing 111 and a coil module 113 disposed in the housing 111. The appearance of the wireless charging stand 10 is mainly presented by the housing 111. The coil module 113 can wirelessly charge an electronic device with a wireless charging function by using the principle of electromagnetic induction after being powered on. In some embodiments, the body 11 is also provided with a power-on interface, an indicator light and other devices. The power-on interface can be a USB interface for electrically connecting the wireless charging stand 10 to an external power source, so as to charge an electronic device with a wireless charging function using the wireless charging stand 10. The indicator light can be used to indicate the working status of the wireless charging stand 10.
[0054] The housing 111 is stacked on the support plate 121 in the second direction, and the second direction is perpendicular to the first direction. Specifically, the second direction can be simply regarded as the thickness direction of the wireless charging stand 10, or as the thickness direction of the body 11. Figure 3 and Figure 4, a rectangular coordinate system is established with the length direction of the carrier plate 121 as the first direction and marked as the X-axis, the thickness direction of the wireless charging stand 10 as the second direction and marked as the Z-axis, and the width direction of the carrier plate 121 as the third direction and marked as the Y-axis. The body 11 can be regarded as being superimposed on the carrier plate 121 in the Z-axis direction. The body 11 can move relative to the carrier plate 121 along the first direction (i.e., the X-axis direction) and simultaneously rotate around the second direction (i.e., the Z-axis direction) so that the coil module 113 is close to or away from the first end 121a.
[0055] Specifically, the housing 111 may include a third end 111a and a fourth end 111b that are arranged opposite to each other. In an embodiment in which the body 11 is in a rectangular block shape, the third end 111a and the fourth end 111b correspond to the two ends of the length direction of the rectangle. In an embodiment in which the body 11 is in other shapes, the third end 111a and the fourth end 111b may be manually designated for reference. In the case of introducing the third end 111a and the fourth end 111b, the positional relationship of the body 11 relative to the support plate 121 may be described in the following manner: the body 11 can move relative to the support plate 121 to the first position and the second position, combined with Figure 2 In the first position, the third end 111a of the body 11 is overlapped with the first end 121a of the support plate 121, and the fourth end 111b of the body 11 is overlapped with the second end 121b of the support plate 121. Figure 5 and Figure 6 , in the second position, the first end 121a is misaligned with the third end 111a, the second end 121b is misaligned with the fourth end 111b, and the coil module 113 is closer to the first end 121a in the second position than in the first position. In other words, in the embodiment where the support plate 121 and the body 11 are both rectangular blocks, in the first position, the length direction of the support plate 121 (i.e., the X-axis direction) is aligned with the length direction of the body 11, and the width direction of the support plate 121 (i.e., the Y-axis direction) is aligned with the width direction of the body 11; in the second position, the length direction of the body 11 forms an angle with the length direction of the support plate 121. Further, in the first position, the circumferential side surface of the support plate 121 can be flush with the circumferential side surface of the body 11 so that the wireless charging stand 10 has a higher appearance integrity. Further, in the second position, the length direction of the body 11 and the length direction of the support plate 121 (i.e., the X-axis direction) are perpendicular to each other.
[0056] The bracket 123 is connected to the support plate 121 and can rotate relative to the support plate 121 to a first state and a second state. Figure 2 In the first state, the bracket 123 is attached to the support plate 121; Figure 6 In the second state, the bracket 123 forms an angle with the first end 121a, and the first end 121a and the bracket 123 are used to stand the body 11 sideways on a support.
[0057] Specifically, in the present embodiment, the bracket 123 is overlapped with the first end 121a in the Z-axis direction in the first state, and the wireless charging stand 10 can be placed flat on a support such as a horizontal table. When the bracket 123 is in this state, regardless of whether the main body 11 rotates relative to the support plate 121, electronic devices such as smart phones, wireless headphones, smart watches, tablet computers, etc. with wireless charging functions can be placed flat on the main body 11 to be wirelessly charged through the wireless charging stand 10. In other words, when the bracket 123 is in this state, the main body 11 can be located at the first position, the second position, or any position between the first position and the second position relative to the support plate 121, and the wireless charging stand 10 can normally charge electronic devices with wireless charging functions. The wireless charging stand 10 can be applicable to wireless charging of various types of electronic devices, thereby improving the versatility of the wireless charging stand 10.
[0058] See also Figure 4 , Figure 6 In some embodiments, a recessed area 12a is provided on the side of the carrier plate 121 facing away from the body 11. Figure 2 , Figure 4 In the first state, the bracket 123 is accommodated in the recessed area 12a. This structure can prevent the bracket 123 from increasing the overall thickness of the wireless charging stand 10, which is conducive to the thin and light design of the wireless charging stand 10. Further, in the first state, the side of the bracket 123 facing away from the body 11 can be flush with the side of the support plate 121 facing away from the body 11. In other words, when the bracket 123 is in the first state, the side surface of the bracket 123 and the support plate 121 facing away from the body 11 can be located in the same plane, so that the wireless charging stand 10 can be stably placed on a horizontal support such as a horizontal tabletop. Further, the recessed area 12a can extend to the circumferential side surface of the first end 121a, and when the bracket 123 is in the first state, the circumferential side surface of the bracket 123 is joined with the circumferential side surface of the support plate 121 to form a continuous contour curved surface, so that the wireless charging stand 10 has a higher appearance integrity.
[0059] Further, refer to Figure 4In some embodiments, the bracket 123 includes a connecting portion 123a and a first rotating portion 123b and a second rotating portion 123c spaced apart at opposite ends of the connecting portion 123a, and the first rotating portion 123b and the second rotating portion 123c are both rotatably connected to the support plate 121. Taking the rotatable connection between the first rotating portion 123b and the support plate 121 as an example, one of the first rotating portion 123b and the support plate 121 may be provided with a rotating shaft, and the other may be provided with an axial hole rotatably matched with the rotating shaft. The rotation structure of the second rotating portion 123c and the support plate 121 may be similar to this. The first rotating portion 123b, the connecting portion 123a, and the second rotating portion 123c form an air avoidance groove 12b to make the bracket 123 roughly U-shaped, and in the first state, part of the structure of the support plate 121 is accommodated in the air avoidance groove 12b. The bracket 123 of the above structure can make the first rotating part 123b and the second rotating part 123c have a relatively long lever arm, and make the center of gravity of the bracket 123 in the second state lower, which is conducive to stabilizing the support plate 121 and the body 11.
[0060] Of course, in other embodiments, the recessed area 12a can be located on the circumferential side of the first end 121a, the bracket 123 can be U-shaped, and the first rotating portion 123b of the bracket 123 is rotatably connected to one end of the support plate 121 in the third direction (i.e., the Y-axis direction), and the second rotating portion 123c of the bracket 123 is rotatably connected to the other end opposite to the third direction of the support plate 121. The bracket 123 can rotate around the Y-axis to fit the first end 121a to be in the first state, or the bracket 123 can form an angle with the first end 121a to be in the second state.
[0061] See also Figure 5 and Figure 6, when the bracket 123 is in the second state, the bracket 123 forms an angle with the first end 121a, and the body 11 can be placed sideways on the support through the first end 121a and the bracket 123. When the bracket 123 is in this state and the body 11 is in the first position, a smart phone, a handheld game console or other similar electronic device with a wireless charging function can be placed vertically on the body 11 to abut against the body 11 and achieve wireless charging. Among them, "vertical placement" can be simply understood as the electronic device being in a vertical screen state, that is, the length direction of the electronic device is consistent with the display direction of its display screen. When the bracket 123 is in the second state and the body 11 is in the first position, the user can apply a torque to the body 11 to rotate the body 11 relative to the support plate 121 around the second direction (i.e., the Z-axis direction) and make the body 11 move downward in the first direction (i.e., the X-axis direction) synchronously, so that the coil module 113 in the body 11 moves in the direction close to the first end 121a, thereby reducing the height of the coil module 113. Smart phones, handheld game consoles or other similar electronic devices with wireless charging function can be placed horizontally against the body 11 and normally perform wireless charging. Among them, "horizontally" can be simply understood as the electronic device is in a horizontal screen state, that is, the length direction of the electronic device is perpendicular to the display direction of its display screen.
[0062] Generally, the receiving coil of a smart phone, handheld game console or other similar electronic device with wireless charging function is set in the central area of the electronic device. When the bracket 123 is in the second state and the body 11 is in the first position, the receiving coil of such electronic device can be basically aligned with the coil module 113 in the body 11 to ensure the efficiency of wireless charging. When such electronic devices are placed horizontally for watching videos or playing games, the height between the receiving coil of the electronic device and the horizontal plane decreases, and when it is directly against the body 11 in the first position, the receiving coil and the coil module 113 will deviate, reducing the efficiency of wireless charging or even making it impossible to perform wireless charging normally. In this case, the user can drive the body 11 to rotate relative to the support plate 121 and make the body 11 move downward toward the first end 121a synchronously, so that the height between the coil module 113 in the body 11 and the horizontal plane decreases to achieve alignment between the coil module 113 and the receiving coil. When the bracket 123 is in the second state and the body 11 is in the second position, when the electronic device is placed horizontally against the body 11, the relative position of the electronic device and the body 11 is roughly the same as when the electronic device is placed vertically on the body 11 in the first position, so that the alignment of the receiving coil and the coil module 113 can be ensured to ensure the efficiency of wireless charging. The above structural design avoids the need to set more than two coil modules 113 in the vertical wireless charging stand 10 to adapt to the horizontal charging scenario of the electronic device, saves the number of coil modules 113 and avoids mutual interference between multiple coil modules 113, thereby saving the cost of the device and ensuring the efficiency of wireless charging.
[0063] In some embodiments, a support structure may be provided on one side of the width direction of the body 11, and the support structure can be extended relative to the housing 111 to enter and exit the housing 111. The support structure may be in the form of a sheet, and it may be manually pushed and pulled to enter and exit the housing 111 of the body 11, or it may be combined with a sensor, a driver, and a control circuit to form an automatically retractable structure. When the body 11 is in the second position, the support structure may extend out of the housing 111 and protrude from the side of the housing 111 facing away from the support plate 121, and the electronic device may be supported by the support structure when it is placed horizontally on the body 11, so as to avoid the electronic device being placed in an unstable manner. Of course, in other embodiments, the support structure may be replaced with a foldable structure, and the support structure may be buckled on the edge of the housing 111 when the body 11 is in the first position to avoid protruding from the side of the housing 111 facing away from the support plate 121, and the body 11 may open the support structure when it is in the second position and be used to support the horizontally placed electronic device to improve the support stability of the electronic device. Of course, the support structure may also be provided at one end of the length direction of the body 11 to play a similar role when the body 11 is in the first position, which will not be described in detail here. Of course, the above-mentioned supporting structure can be arranged on the support plate 121 to play a similar role, which will not be described in detail here.
[0064] In the wireless charging stand 10, when the bracket 123 is stacked on the first end 121a of the support plate 121, that is, when the bracket 123 is in the first state, the wireless charging stand 10 can be placed flat on a support such as a desktop, and mobile phones, tablet computers, wireless headphones, smart watches and other electronic devices with wireless charging functions can be placed on the wireless charging stand 10 for wireless charging. The wireless charging stand 10 can be applied to wireless charging of various types of electronic devices, thereby improving the versatility of the wireless charging stand 10 and making the wireless charging stand 10 relatively small in size for easy storage or carrying. When the bracket 123 rotates so that the body 11 can stand sideways on the support and the housing 111 is in the first position, mobile phones and tablet computers with wireless charging functions can be placed vertically on the body 11 for wireless charging and convenient for users to use electronic devices. When the bracket 123 rotates so that the main body 11 can stand on its side on a support and the shell 111 is in the second position, the height between the coil module 113 and the first end 121a is reduced, and electronic devices such as mobile phones with wireless charging function can be placed horizontally on the main body 11 for wireless charging and convenient for users to use electronic devices, so as to ensure charging efficiency and improve convenience of use, and can expand the use scenarios of electronic devices.
[0065] Of course, in other embodiments, the positions of the bracket 123 and the support plate 121 can be relatively fixed, that is, the bracket 123 can be fixedly connected to the support plate 121, for example, the bracket 123 can be integrally formed with the support plate or the bracket 123 can be welded to the support plate, so that the wireless charging stand 10 can stand on the support and wirelessly charge electronic devices such as smart phones and tablet computers. In this embodiment, after the body 11 moves from the first position to the second position relative to the support plate 121, the height between the coil module 113 and the first end 121a decreases, so that it can adapt to the wireless charging of horizontal screen electronic devices. In other words, in this embodiment, the body 11 of the wireless charging stand 10 can stand on the horizontal plane, and the height between the coil module 113 and the horizontal plane when the body 11 is in the first position is greater than the height between the coil module 113 and the horizontal plane when the body 11 is in the second position, so that it can be suitable for wireless charging of electronic devices in the vertical screen state and wireless charging of electronic devices in the horizontal screen state.
[0066] See also Figure 4 The first protrusion 115a and the second protrusion 115b are provided on one side of the housing 111 facing the support plate 121 and one of the support plates 121, and the first protrusion 115a and the second protrusion 115b are arranged at intervals. Figure 3 The first guide groove 121c and the second guide groove 121d are provided on one side of the housing 111 facing the support plate 121 and the other side of the support plate 121. Figure 7 and Figure 8 The first protrusion 115a is inserted into the first guide groove 121c, and the second protrusion 115b is inserted into the second guide groove 121d. The first protrusion 115a slides with the first guide groove 121c to guide the body 11 to move in the first direction, and the second protrusion 115b slides with the second guide groove 121d to guide the body 11 to rotate synchronously around the second direction.
[0067] Specifically, in this embodiment, the first protrusion 115a and the second protrusion 115b are both disposed on the housing 111, and the first protrusion 115a and the second protrusion 115b may be cylindrical and integrally formed with the housing 111. Of course, in other embodiments, the first protrusion 115a and the second protrusion 115b may also be assembled and formed on the housing 111, for example, the first protrusion 115a and the second protrusion 115b may be riveted or threadedly connected to the housing 111. The first guide groove 121c and the second guide groove 121d are both provided on the carrier plate 121, and the first guide groove 121c extends along the first direction (i.e., the X-axis direction), the first guide groove 121c is straight and has a first end A1 and a second end B1, the second guide groove 121d is curved and has a third end A2 and a fourth end B2, the line connecting the first end A1 and the third end A2 extends along the third direction (i.e., the Y-axis direction) of the carrier plate 121, the fourth end B2 is located on the extension line of the first guide groove 121c in the first direction (i.e., the X-axis direction), and the fourth end B2 is closer to the first end 121a than the third end A2. Figure 8 As shown, when the body 11 is in the first position, the first protrusion 115a is close to and limited to the first end A1 and the second protrusion 115b is close to and limited to the third end A2, and the center line of the first protrusion 115a and the center line of the second protrusion 115b are perpendicular to the extension direction of the first guide groove 121c (i.e., the X-axis direction). In other words, when the body 11 is in the first position and the body 11 is standing on the horizontal support surface, the center line of the first protrusion 115a and the second protrusion 115b can be parallel to the third direction of the support plate 121 (i.e., the Y-axis direction). Fig. 9 and Fig.10 In the second position, the first protrusion 115a is close to and limited at the second end B1, the second protrusion 115b is close to and limited at the fourth end B2, and the center line of the first protrusion 115a and the center line of the second protrusion 115b are parallel to the extension direction of the first guide groove 121c (i.e., the X-axis direction). In other words, when the body 11 is in the second position and the body 11 is sideways on the horizontal support surface, the center line of the first protrusion 115a and the second protrusion 115b can be perpendicular to the second direction of the carrier plate 121 (i.e., the Y-axis direction).
[0068] Specifically, in this embodiment, the first guide groove 121c and the second guide groove 121d are both blind grooves, that is, the first guide groove 121c and the second guide groove 121d do not need to extend to the surface of the carrier plate 121 facing away from the body 11. Of course, in other embodiments, at least one of the first guide groove 121c and the second guide groove 121d may be a through groove. Fig.11, the solid lines in the figure show the relative positions of the first protrusion 115a, the second protrusion 115b and the support plate 121, the first guide groove 121c, and the second guide groove 121d when the housing 111 is in the first position, and the dotted lines show the relative positions of the first protrusion 115a, the second protrusion 115b and the support plate 121, the first guide groove 121c, and the second guide groove 121d when the housing 111 is in the second position. With the first position as a reference, the origin of the coordinate system of the support plate 121 can be fixed at the center of the first end A1 of the first guide groove 121c and used as the inherent coordinate system of the support plate 121 to distinguish it from the original reference coordinate system (X, Y, Z), and make the center line of the first end A1 of the first guide groove 121c and the center line of the third end A2 of the second guide groove 121d coincide with the y-axis of the inherent coordinate system of the support plate 121, then the center trajectory equation of the second guide groove 121d is:
[0069]
[0070] In formula (1), r is the length of the center line connecting the first end A1 and the third end A2, a is the length of the center track line of the first guide groove 121c, It can be regarded as the angle formed by the housing 111 and the y-axis after the housing 111 rotates relative to the first position, where t∈(0,1). The second guide groove 121d whose center trajectory satisfies the above equation (1) can make the body 11 move along the X-axis while rotating around the Z-axis, and can make the length direction of the body 11 parallel to the X-axis direction when in the first position, and perpendicular to the X-axis direction when in the second position, that is, the rotation angle range of the body 11 relative to the carrier plate 121 is 0 degrees to 90 degrees.
[0071] Further, in order to make the housing 111 centered in the first position, and to make the housing 111 still centered in the horizontal direction (i.e., the y-axis direction) in the second position, and to make the bottom end of the housing 111 in the second position aligned with the first end 121a of the carrier plate 121 to improve the appearance coordination and convenience of use of the wireless charging stand 10, the center of the first protrusion 115a can be set at the center of the rectangle of the cross section of the housing 111, and the following relationship is satisfied while satisfying the above relationship (1):
[0072]
[0073] In formula (2), L is the length of the long side of the rectangle, D is the length of the short side of the rectangle, and a is the length of the center track line of the first guide groove 121c. Of course, it can be understood that this setting is not necessary.
[0074] refer to Fig.12In the embodiment where the first protrusion 115a and the second protrusion 115b are arranged on the support plate 121, and the first guide groove 121c and the second guide groove 121d are arranged on the housing 111, when the housing 111 is in the first position, the relative positions of the first guide groove 121c, the second guide groove 121d and the support plate 121, the first protrusion 115a, and the second protrusion 115b are shown as solid lines; when the housing 111 is in the second position, the relative positions of the first guide groove 121c, the second guide groove 121d and the support plate 121, the first protrusion 115a, and the second protrusion 115b are shown as dotted lines. Fig.12 After the coordinate system is replaced and fixed to the housing 111, the above equations (1) and (2) can still hold. The difference between this embodiment and the first guide groove 121c and the second guide groove 121d being arranged on the carrier plate 121 is that, in order to ensure the appearance coordination of the entire wireless charging stand 10 when the housing 111 is in the second position, the center of the second end B1 of the first guide groove 121c can be arranged at the center of the rectangle of the cross section of the housing 111.
[0075] Further, refer to Fig.13In some embodiments, the wireless charging stand 10 may include a first fan 13, and when the body 11 is in the second position, the first fan 13 can be installed on the support plate 121 and the air outlet of the first fan 13 faces the body 11. The first fan 13 can send air to the body 11 to facilitate the heat dissipation of the coil module 113 in the body 11, thereby preventing the body 11 from being overheated and having an adverse effect on the charging efficiency of the wireless charging stand 10. For electronic devices with higher charging power, the first fan 13 can effectively increase the heat dissipation efficiency of the wireless charging stand 10. For electronic devices with relatively low charging efficiency, the first fan 13 is not necessary, and thus can be detached from the support plate 121, so that the body 11 can be smoothly moved back to the first position, thereby facilitating the storage or carrying of the wireless charging stand 10. It can be understood that no matter whether the bracket 123 is in the first state or the second state, the body 11 is in the second position, and the first fan 13 can be installed on the support plate 121 or detached from the support plate 121. Further, in some embodiments, a slot 121e may be provided at the second end 121b of the carrier plate 121, and a foldable metal pin 131 may be provided on one side of the first fan 13. When the body 11 is located at the second position, the metal pin 131 may be opened to make the metal pin 131 protrude from the housing of the first fan 13, and then the first fan 13 may be pluggably installed in the slot 121e of the carrier plate 121 through the metal pin 131. After the metal pin 131 is inserted into the slot 121e, the first fan 13 may be connected to the control circuit inside the body 11 or inside the carrier plate 121, and then the first fan 13 may be used to dissipate heat for the body 11 and the electronic device against the body 11. Of course, in other embodiments, the metal pin 131 may be fixed in position relative to the housing of the first fan 13, that is, the metal pin 131 does not need to be configured as a foldable structure.
[0076] See also Fig.14 and Fig.15The housing 111 is provided with an installation cavity 11a, and the coil module 113 is arranged in the installation cavity 11a. The coil module 113 may include a coil 113a, a magnetic isolation sheet 113b and a support sheet 113c which are stacked in sequence. The coil 113a is located on the side of the magnetic isolation sheet 113b which is not facing the support plate 121, and the support sheet 113c is fixedly connected to the housing 111. The magnetic isolation sheet 113b may be made of ferrite wave absorbing material, which has excellent magnetic conductivity, can increase the magnetic flux of the coil 113a module 113 and reduce the loss of the coil 113a module 113, and can make the magnetic flux lines tightly surround the surrounding area centered on the magnetic isolation sheet 113b to increase the electromagnetic induction intensity and improve the electromagnetic conversion efficiency. The side of the support sheet 113c facing the coil 113a may be coated with a heat dissipation material such as silicone grease, so as to facilitate the heat of the coil 113a to be conducted to the housing 111 and dissipated into the air through the housing 111. Of course, the support sheet 113c may also be made of metal or non-metal material with good thermal conductivity to facilitate heat dissipation of the coil 113a. Of course, the magnetic isolation sheet 113b and the support sheet 113c may be omitted.
[0077] Further, the housing 111 may be provided with an air hole 11b connected to the mounting cavity 11a, and the body 11 includes a circuit board 117 and a second fan 118 disposed in the mounting cavity 11a, and the circuit board 117 and the second fan 118 are spaced apart at opposite ends of the coil module 113. The coil 113a and the second fan 118 are both electrically connected to the circuit board 117. During the process of the coil module 113 wirelessly charging the electronic device, the second fan 118 may be started to supply air to the coil module 113, so that the air in the mounting cavity 11a generates convection with the outside air through the air hole 11b, so as to improve the heat dissipation performance of the wireless charging stand 10. The spacing between the circuit board 117 and the second fan 118 can make the coil 113a and the circuit board 117 located on the same side of the air outlet of the second fan 118, so as to facilitate the heat dissipation of the circuit board 117 and the coil module 113 by the second fan 118.
[0078] Further, in some embodiments, the side of the support sheet 113c facing away from the coil 113a may be spaced apart from the housing 111 and form a channel 11c. For example, in this embodiment, a boss is provided on the side of the support sheet 113c facing away from the coil 113a, and the boss is connected to the housing 111, so that a channel 11c is formed between the support sheet 113c and the housing 111. When the coil module 113 is charging the electronic device, the airflow sent by the second fan 118 may flow through the channel 11c and the surface of the coil 113a to improve the heat dissipation efficiency of the coil module 113.
[0079] Furthermore, in this embodiment, air holes 11b are provided on the circumferential side surfaces of the third end 111a and the fourth end 111b, and the second fan 118 can extract air from one of the third end 111a or the fourth end 111b and supply air to the other of the third end 111a and the fourth end 111b, so as to facilitate heat dissipation of the coil module 113 and the circuit board 117. Of course, in other embodiments, air holes 11b can also be provided at other positions of the circumference of the housing 111.

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.

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.
