[0033] The following further describes the implementation manner of the present application in detail in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0034] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present application. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0035] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "communicate" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0036] During wireless charging, heat is generated between the electronic device and the wireless charging device, which is likely to cause the temperatures of the electronic device and the wireless charging device to rise. High temperatures may pose safety hazards and may also cause an extension of the charging time.

[0037] In the related art, heat is usually dissipated by direct contact or by blowing air with a fan. Among them, when dissipating heat by blowing air with a fan, the air blown by the fan is usually guided to the charging surface where the wireless charging device contacts the electronic device to dissipate heat and cool the charging surface and the electronic device. The air blown by the fan does not pass through the charging module, resulting in a problem of low heat dissipation efficiency.

[0038] Based on the above situation, an embodiment of the present application provides a wireless charging device 10. Please refer to Figures 1 to 7 , the wireless charging device 10 includes a housing 11, a charging module 12 and a fan 13. The housing 11 has a first accommodation space 111a, a second accommodation space 112a and a communication port 11a. The first accommodation space 111a is communicated with the second accommodation space 112a through the communication port 11a, and the communication port 11a is located on one side of the second accommodation space 112a along the thickness direction of the housing 11. The charging module 12 is disposed in the second accommodation space 112a. The fan 13 is disposed in the first accommodation space 111a, and the charging module 12 and the fan 13 are arranged along a first direction. The first direction intersects with the thickness direction of the housing 11. The air generated by the fan 13 can at least blow towards the charging module 12 through the communication port 11a.

[0039] It should be noted that the electronic devices applicable to the wireless charging device 10 can be devices such as mobile phones, tablet computers, earphones, smart watches, sports bracelets, etc. that can perform wireless charging.

[0040] It should be noted that the wireless charging device 10 can be a wireless charging stand, a wireless charging base, etc., which is not limited herein.

[0041] In addition, the wireless charging device 10 can be fixed in the vehicle for use, or can be fixed on the desktop for use, which is not limited herein.

[0042] Exemplarily, the housing 11 is formed with a connecting portion 14b, and the connecting portion 14b is used for connecting with a universal ball head.

[0043] The charging module 12 can perform wireless charging on the electronic device placed on the wireless charging device 10.

[0044] Exemplarily, the charging module 12 performs wireless charging by electromagnetic induction.

[0045] Exemplarily, the wireless charging standard of the charging module 12 is QI2.0.

[0046] The fan 13 is used for generating air, and has an air outlet and an air inlet. In addition, the wind speed of the fan 13 is controllable, and the wireless charging device 10 can adjust the wind speed of the fan 13 according to the temperature generated during charging, so as to achieve different heat dissipation efficiencies.

[0047] Exemplarily, the fan 13 is a centrifugal fan 13.

[0048] It should be noted that the wireless charging device 10 can be in a flat shape, that is, in the shape of a cube with a relatively small height dimension, or other shapes.

[0049] Exemplarily, the housing 11 is in a flat shape, and the thickness direction of the housing 11 is the height direction of the housing 11.

[0050] In addition, the first direction can be the length direction or the width direction of the wireless charging device 10, and no limitation is made here.

[0051] The first direction intersects with the thickness direction of the housing 11, which means that the first direction is not parallel to the thickness direction of the housing 11.

[0052] Exemplarily, the first direction is perpendicular to the thickness direction of the housing 11.

[0053] The first accommodation space 111a communicates with the second accommodation space 112a through the communication port 11a, and the communication port 11a is located on one side of the second accommodation space 112a along the thickness direction of the housing 11. That is to say, the first accommodation space 111a and the second accommodation space 112a are arranged in sequence along the thickness direction of the housing 11.

[0054] The fan 13 is arranged in the first accommodation space 111a, and the charging module 12 and the fan 13 are arranged in the first direction, which means that the charging module 12 and the fan 13 are staggeredly arranged in the thickness direction of the housing 11, so that the fan 13 in the first accommodation space 111a does not directly face the charging module 12 in the second accommodation space 112a along the thickness direction of the housing 11, thereby improving the structural compactness in the thickness direction of the housing 11, and thus reducing the thickness of the wireless charging device 10.

[0055] The wind generated by the fan 13 can at least blow towards the charging module 12 through the communication port 11a. That is to say, the wind generated by the fan 13 in the first accommodation space 111a can directly blow from the communication port 11a between the first accommodation space 111a and the second accommodation space 112a along the thickness direction of the housing 11 towards the second accommodation space 112a and can reach the charging module 12 in the second accommodation space 112a, thereby cooling and dissipating heat from the charging module 12.

[0056] The wireless charging device 10 provided by the embodiment of the present application includes a housing 11, a charging module 12, and a fan 13. The housing 11 has a first accommodation space 111a and a second accommodation space 112a that are communicated through a communication port 11a. The communication port 11a is provided on one side of the second accommodation space 112a along the thickness direction of the housing 11. By arranging the first accommodation space 111a and the second accommodation space 112a along the thickness direction of the housing 11, the charging module 12 and the fan 13 are arranged along a first direction. In this way, the wind generated by the fan 13 can first reach the communication port 11a along the first direction, and then blow into the second accommodation space 112a along the thickness direction of the housing 11 through the communication port 11a and directly blow onto the charging module 12, shortening the flow path of the cooling air and improving the heat dissipation efficiency of the charging module 12. In addition, by arranging the charging module 12 and the fan 13 staggeredly in the thickness direction of the housing 11, the compactness of the wireless charging device 10 in the thickness direction of the housing 11 is improved, and the thickness dimension of the wireless charging device 10 is reduced.

[0057] In some embodiments, please refer to Figure 4 、 Figure 5 and Figure 7 , along the first direction, the air outlet of the fan 13 faces the side of the communication port 11a.

[0058] It can be understood that the air outlet of the fan 13 faces the side of the communication port 11a along the first direction, which can make the wind generated by the fan 13 directly blow onto the communication port 11a, further shortening the flow path of the cooling air, thereby improving the heat dissipation efficiency of the cooling air for the charging module 12.

[0059] In some embodiments, please refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 7 , the wireless charging device 10 includes a flow guiding member 14. The flow guiding member 14 is arranged on the side of the communication port 11a along the thickness direction of the housing 11 away from the second accommodation space 112a, and is used to guide the wind generated by the fan 13 to the communication port 11a.

[0060] It should be noted that the flow guiding member 14 can be a flow guiding plate or other forms, which is not limited herein.

[0061] The flow guiding member 14 is arranged on the side of the communication port 11a along the thickness direction of the housing 11 away from the second accommodation space 112a, that is to say, the flow guiding member 14 is arranged in the first accommodation space 111a and can jointly define a first air duct with the housing 11. The two ends of the first air duct are respectively communicated with the air outlet of the fan 13 and the communication port 11a, so as to guide the wind generated by the fan 13 to the communication port 11a.

[0062] In some embodiments, please refer to Figures 4 to 5, in the direction away from the fan 13, the distance between the guiding portion 14a of the guiding member 14 and the communication port 11a in the thickness direction of the housing 11 decreases.

[0063] Exemplarily, the direction away from the fan 13 is the first direction.

[0064] The guiding member 14 is formed with a guiding portion 14a and a connecting portion 14b. Among them, the distance between the guiding portion 14a and the communication port 11a in the thickness direction of the housing 11 can decrease gradually or in stages, so that the first air duct becomes smaller closer to the communication port 11a, guiding the wind to the communication port 11a as much as possible, which is beneficial to reducing wind resistance, increasing the wind speed, and thus improving the heat dissipation efficiency of the wireless charging device 10.

[0065] Specifically, the guiding member 14 is connected to the housing 11 through the connecting portion 14b.

[0066] Exemplarily, a connecting groove is formed on the inner wall of the first accommodation space 111a. The connecting portion 14b is provided at one end of the guiding member 14 away from the fan 13, and at least part of the connecting portion 14b is parallel to the plane perpendicular to the thickness direction of the housing 11 and extends into the connecting groove for limit cooperation with the connecting groove. The guiding member 14 is also formed with a connecting hole, and the guiding member 14 is cooperated with the connecting hole and the housing 11 through fasteners respectively, so as to realize the fixation of the guiding member 14.

[0067] Exemplarily, the housing 11 includes a first sub-housing 111 and a second sub-housing 112. The first sub-housing 111 forms a first accommodation space 111a, and the second sub-housing 112 forms a second accommodation space 112a. The second sub-housing 112 is disposed on one side of the first sub-housing 111 in the thickness direction of the housing 11. The first sub-housing 111 is divided into a front shell 1111 and a rear shell 1112. The front shell 1111 is located on the side close to the second sub-housing 112 in the thickness direction of the housing 11. The front shell 1111 and the rear shell 1112 enclose and define the connecting groove, which is convenient for the installation and disassembly of the guiding member 14.

[0068] Exemplarily, as Figure 5 shown, the connecting groove is formed with a flange extending towards the second accommodation space 112a in the thickness direction of the housing 11. The connecting portion 14b is formed with a clamping portion cooperating with the flange, and the clamping portion and the flange are limitedly cooperated at least in the first direction. At the same time, a part of the inner wall of the front shell 1111 close to the fan 13 protrudes, and can abut the guiding member 14 against the rear shell 1112 in the thickness direction of the housing 11, so as to improve the fixing strength of the housing 11 on the guiding member 14 and improve the situation that the guiding member 14 is prone to vibration under the action of wind force.

[0069] Thus, by reducing the distance between the guiding portion 14a of the guiding member 14 and the communication port 11a in the thickness direction of the housing 11, the first air duct becomes smaller closer to the communication port 11a, guiding the wind to the communication port 11a as much as possible, increasing the wind speed blown by the fan 13, and thus enhancing the output power of the fan 13.

[0070] In some embodiments, refer to Figures 1 to 7 , the housing 11 includes a first sub-housing 111 and a second sub-housing 112. The first sub-housing 111 forms a first accommodation space 111a. The second sub-housing 112 forms a second accommodation space 112a. The second sub-housing 112 is disposed on one side of the first sub-housing 111 in the thickness direction of the housing 11.

[0071] The second sub-housing 112 is disposed on one side of the first sub-housing 111 in the thickness direction of the housing 11, that is, the first sub-housing 111 and the second sub-housing 112 are arranged in sequence in the thickness direction of the housing 11.

[0072] Since the charging module 12 is disposed in the second accommodation space 112a of the second sub-housing 112, the second sub-housing 112 can be used to contact the electronic device and perform wireless charging on the electronic device.

[0073] Exemplarily, the first sub-housing 111 is in a long strip shape, and the second sub-housing 112 is in a disc shape.

[0074] Exemplarily, the first sub-housing 111 includes a front shell 1111 and a rear shell 1112. An air inlet is provided on the side wall 1111d of the rear shell 1112 away from the second sub-housing 112, and the air inlet is communicated with the air inlet of the fan 13. Thus, during charging, the air inlet of the first sub-housing 111 faces away from the electronic device, thereby improving the air suction effect of the air inlet, and at the same time, the temperature of the air inhaled by the air inlet is lower than the air near the electronic device, thereby improving the heat dissipation and cooling effect.

[0075] In some embodiments, refer to Figures 4 to 7 , an exhaust passage 1122a communicating with the second accommodation space 112a is provided on the side wall 1111d of the second sub-housing 112. The air in the second accommodation space 112a can be discharged through the exhaust passage 1122a.

[0076] An exhaust passage 1122a communicating with the second accommodation space 112a is provided on the side wall 1111d of the second sub-housing 112, and the other end of the exhaust passage 1122a communicates with the outside.

[0077] It should be noted that the exhaust passage 1122a may be formed by the second sub-housing 112, or may be jointly defined by the first sub-housing 111 and the second sub-housing 112.

[0078] The number of the exhaust air channels 1122a can be one, two, three, four, five, six, seven, eight, nine, ten, etc., without limitation herein.

[0079] Exemplarily, the second sub-shell 112 has a charging panel 1121 on a side away from the communication port 11a. The charging panel 1121 contacts with an electronic device to charge the electronic device. The air blown from the first accommodation space 111a in the thickness direction of the housing 11 towards the second accommodation space 112a can be discharged through the exhaust air channels 1122a after cooling and dissipating heat from the charging module 12 in the second accommodation space 112a. Since the exhaust air channels 1122a are provided on the side wall 1111d of the second sub-shell 112, and the size of the electronic device is usually larger than that of the charging panel 1121, after the air is discharged from the side of the charging panel 1121, it can pass through the surface of the periphery of the contact position between the electronic device and the charging panel 1121, taking away the heat on the surface of the electronic device, thereby being able to cool the electronic device and improving the heat dissipation efficiency of the wireless charging device 10.

[0080] By discharging the air in the second accommodation space 112a through the exhaust air channels 1122a, the air generated by the fan 13 can sequentially pass through the first accommodation space 111a, the communication port 11a, the second accommodation space 112a, and the exhaust air channels 1122a, making the cooling air more sufficient in cooling the charging module 12, improving the heat dissipation effect on the charging module 12, and at the same time being able to take away the heat on the surface of the electronic device, thereby improving the overall heat dissipation efficiency of the wireless charging device 10.

[0081] In some embodiments, please refer to Figures 1 to 7 , the outer wall of the first sub-shell 111 on the side close to the second sub-shell 112 in the thickness direction of the housing 11 is recessed to form a groove 1111a. At least part of the second sub-shell 112 is disposed in the groove 1111a. A first opening 1111b is provided on the groove wall of the groove 1111a in the thickness direction of the housing 11. The second sub-shell 112 is correspondingly provided with a second opening 1122b. The first opening 1111b and the second opening 1122b cooperate to form the communication port 11a.

[0082] It should be noted that the size of the groove 1111a is larger than the size of the second sub-shell 112 located in the groove 1111a, so that the second sub-shell 112 can be disposed in the groove 1111a.

[0083] At least part of the second sub-shell 112 being disposed in the groove 1111a may mean that the entire second sub-shell 112 is disposed in the groove 1111a, or part of it is disposed in the groove 1111a and part of it is exposed from the groove 1111a in the thickness direction of the housing 11.

[0084] The groove wall of the groove 1111a along the thickness direction of the housing 11 is provided with a first opening 1111b, that is, the bottom wall 1111c of the groove 1111a is provided with the first opening 1111b.

[0085] The second sub-housing 112 is correspondingly provided with a second opening 1122b. That is to say, a second opening 1122b is formed on the side wall 1111d of the second sub-housing 112 close to the first sub-housing 111.

[0086] The first opening 1111b and the second opening 1122b cooperate to form a communication port 11a, which means that the first opening 1111b and the second opening 1122b jointly define and form the communication port 11a, thereby communicating the first accommodation space 111a and the second accommodation space 112a.

[0087] In this way, by the outer wall of the first sub-housing 111 on the side close to the second sub-housing 112 along the thickness direction of the housing 11 being recessed to form the groove 1111a, at least part of the second sub-housing 112 is arranged in the groove 1111a, so that the thickness of the housing 11 is smaller, and the overall compactness of the wireless charging device 10 is improved.

[0088] In some embodiments, please refer to Figure 4 、 Figure 5 and Figure 7 , along the direction away from the bottom wall 1111c of the groove 1111a along the thickness direction of the housing 11, the distance between the side wall 1111d of the groove 1111a and the center line of the first opening 1111b increases.

[0089] It should be noted that the first opening 1111b can be circular, and the center line of the circle is parallel to the thickness direction of the housing 11.

[0090] Exemplarily, the distance between the side wall 1111d of the groove 1111a and the center line of the first opening 1111b can increase gradually.

[0091] At the same time, the extending direction of the side wall 1111d of the groove 1111a is not parallel to the thickness direction of the housing 11 and forms a certain angle, that is, in the cross-section perpendicular to the thickness direction of the housing 11, the closer the groove 1111a is to the notch, the larger the size.

[0092] Exemplarily, at least part of the side wall 1111d of the groove 1111a is an arc surface, and the side wall 1111d of the groove 1111a is transitionally connected to the non-groove 1111a area of the first sub-housing 111 through the arc surface.

[0093] In the direction away from the bottom wall 1111c of the groove 1111a along the thickness direction of the housing 11, the distance between the side wall 1111d of the groove 1111a and the center line of the first opening 1111b increases, so that the side wall 1111d of the groove 1111a can be transitionally connected to the non-groove 1111a area of the first sub-shell 111, making the appearance of the first sub-shell 111 more beautiful. In addition, it is more conducive to reducing wind resistance, thereby improving the heat dissipation effect.

[0094] In some embodiments, the side wall 1111d of the second sub-shell 112 is spaced from the groove wall of the groove 1111a, and the wind discharged from the exhaust air passage 1122a can be discharged from the gap between the side wall 1111d of the second sub-shell 112 and the groove wall of the groove 1111a.

[0095] It should be noted that after the wind discharged from the exhaust air passage 1122a is discharged from the gap between the side wall 1111d of the second sub-shell 112 and the groove wall of the groove 1111a, it can blow towards the electronic device, thereby taking away the heat on the surface of the electronic device to dissipate heat from the electronic device.

[0096] In some embodiments, please refer to Figure 4 and Figure 5 , along the direction away from the second accommodation space 112a, the cross-sectional area of the exhaust air passage 1122a increases.

[0097] Along the direction away from the second accommodation space 112a, that is, the exhaust direction of the exhaust air passage 1122a.

[0098] The cross-sectional area of the exhaust air passage 1122a increases with the exhaust direction, which can reduce wind resistance and increase the wind speed, thereby improving the heat dissipation efficiency.

[0099] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 7 , a charging panel 1121 is provided on the side of the second sub-shell 112 away from the second opening 1122b along the thickness direction of the housing 11. One end of the exhaust air passage 1122a away from the second accommodation space 112a faces away from the charging panel 1121.

[0100] The charging panel 1121 is used to contact the electronic device, and the charging module 12 is arranged close to the charging panel 1121 to charge the electronic device.

[0101] The exhaust passage 1122a is provided on the side of the second sub-shell 112. At the same time, the end of the exhaust passage 1122a away from the second accommodation space 112a, that is, the end communicating with the outside, faces away from the charging panel 1121. As a result, the air discharged from the exhaust passage 1122a first contacts the bottom wall 1111c and the side wall 1111d of the groove 1111a. The side wall 1111d has a certain blocking effect on the air and guides the air to blow along the side wall 1111d onto the charging surface of the electronic device, thereby improving the heat dissipation and cooling effect on the electronic device.

[0102] In some embodiments, please refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 7 ,the flow guide member 14 divides the first accommodation space 111a into a first cavity 111b and a second cavity 111c. The second cavity 111c is located on the side of the flow guide member 14 away from the second accommodation space 112a. The flow guide member 14 has a through hole 14c. The through hole 14c communicates the first cavity 111b and the second cavity 111c. The wireless charging device 10 includes a first circuit board 15. The first circuit board 15 is disposed in the second cavity 111c.

[0103] Specifically, the flow guide member 14 is substantially parallel to the plane perpendicular to the thickness direction of the housing 11, so as to divide the first accommodation space 111a into a first cavity 111b and a second cavity 111c formed in sequence along the thickness direction of the housing 11.

[0104] The second cavity 111c is located on the side of the flow guide member 14 away from the second accommodation space 112a. That is to say, the first cavity 111b forms a first air duct and is used to guide the air of the fan 13 to the communication port 11a.

[0105] The through hole 14c of the flow guide member 14 can be provided in the flow guiding portion 14a.

[0106] The through hole 14c communicates the first cavity 111b and the second cavity 111c, so that the air in the first cavity 111b can enter the second cavity 111c through the through hole 14c.

[0107] Exemplarily, the first circuit board 15 can be a main circuit board for controlling the fan 13 and the charging module 12.

[0108] It should be noted that the first circuit board 15 is also provided with a power connection port, and the power connection port is used to supply electric energy to the wireless charging device 10.

[0109] Exemplarily, the power connection port is a USB interface or a Type-C interface, etc., which is not limited here.

[0110] The first circuit board 15 is disposed in the second cavity 111 c , so that the wind in the first cavity 111 b enters the second cavity 111 c through the through hole 14 c to dissipate heat and cool the first circuit board 15 .

[0111] Exemplarily, the wireless charging device 10 further includes a second circuit board 17, on which a button is provided, and the button is used to turn on and off the wireless charging device 10. The second circuit board 17 is also provided with an indicator light, which can be displayed through the key cap on the housing 11, thereby prompting the user.

[0112] Exemplarily, the buttons and indicator lights are both arranged on the first circuit board 15, and the first circuit board 15 has both control and switch functions.

[0113] Therefore, the first circuit board 15 disposed in the second cavity 111 c can be cooled and dissipated through the via holes 14 c formed on the guide member 14 , thereby improving the overall heat dissipation effect of the wireless charging device 10 and improving the heating of the first circuit board 15 .

[0114] In some embodiments, the wireless charging device 10 includes a connecting wire. The connecting wire is passed through the via hole 14c. The first circuit board 15 is electrically connected to the charging module 12 at least through the connecting wire.

[0115] It should be noted that the connecting wire is used to control and drive the charging module 12 or the fan 13 .

[0116] The connecting wires can also realize electrical connection between the first circuit board 15 and the fan 13 , and between the first circuit board 15 and the second circuit board 17 .

[0117] The connection line between the first circuit board 15 and the fan 13 may pass through the via hole 14c or may not pass through the via hole 14c.

[0118] Likewise, the connection line between the first circuit board 15 and the second circuit board 17 may pass through the via hole 14c or may not pass through the via hole 14c.

[0119] Here, by passing the connection line between the first circuit board 15 and the charging module 12 through the via hole 14 c , the electrical circuit layout inside the wireless charging device 10 is simplified, and the structure for the electrical circuit layout is simplified.

[0120] For some examples, see Figure 2 and Figure 4 The wireless charging device 10 includes a sealing plug 16 . The sealing plug 16 is disposed in the via hole 14 c . The connecting wire is passed through the sealing plug 16 .

[0121] The sealing plug 16 is disposed in the through hole 14c and can roughly seal the through hole 14c, so that most of the wind generated by the fan 13 enters the second accommodation space 112a from the communication port 11a, cooling the charging module 12 and the electronic device, thereby improving the situation where the main heat generation during charging is concentrated on the charging module 12 and the electronic device.

[0122] Exemplarily, the outer periphery of the sealing plug 16 is snap-fitted with the through hole 14c. The four soft rubbers in the middle of the sealing plug 16 can deform. As the connection line passes through the sealing plug 16 from one end, the soft rubbers can closely adhere to the connection line and gather towards the connection line, so that the sealing plug 16 can adapt to different specifications and quantities of connection lines and keep the through hole 14c sealed as much as possible.

[0123] In this way, by disposing the sealing plug 16 in the through hole 14c and threading the connection line through the sealing plug 16, the through hole 14c can be sealed as much as possible while keeping the electrical circuit layout simple, so that most of the wind generated by the fan 13 enters the second accommodation space 112a from the communication port 11a, cooling the charging module 12 and the electronic device, thereby improving the situation where the main heat generation during charging is concentrated on the charging module 12 and the electronic device.

[0124] In some embodiments, please refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 7 , the second sub-shell 112 includes a charging panel 1121 and a lower shell 1122. The charging panel 1121 is disposed on the side of the lower shell 1122 away from the communication port 11a. An exhaust passage 1122a is formed on the side wall 1111d of the lower shell 1122.

[0125] It should be noted that the charging panel 1121 is used to contact the electronic device. Therefore, the charging panel 1121 is usually flat, and the charging module 12 is disposed close to the charging panel 1121 to charge the electronic device.

[0126] Exemplarily, the charging panel 1121 and the lower shell 1122 are connected by bonding.

[0127] It should be noted that a second opening 1122b is further formed in the lower shell 1122.

[0128] The exhaust passage 1122a is formed on the side wall 1111d of the lower shell 1122, so that the wind in the second accommodation space 112a can be discharged at one end away from the charging panel 1121 and the charging module 12, thereby reducing the wind disturbance of the cooling wind to the charging module 12 and improving the stability of the charging module 12.

[0129] In some embodiments, the charging module 12 includes a coil assembly 121 and a magnetic member 122. The magnetic member 122 is disposed on a side of the coil assembly 121 close to the charging panel 1121.

[0130] It should be noted that the wireless charging device 10 provided in this application can have a magnetic attraction function, that is to say, the wireless charging device 10 can magnetically attract the electronic device while charging the electronic device, so as to improve the situation that the electronic device is likely to move during wireless charging.
