[0053] 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.

[0054] like Figures 1 to 3As shown, in one embodiment, a wireless charging device 10 is provided, and the wireless charging device 10 has two fans, and the heat dissipation duct 30 formed has a better heat dissipation effect. It can be understood that the wireless charging device 10 with multiple fans is also within the protection scope of the present application. When the wireless charging device 10 charges the device to be charged 20, the heat dissipation duct 30 can not only reduce the temperature of the wireless charging device 10 itself, but also the air flow can flow through the side of the device to be charged 20 facing the wireless charging device 10, so that the temperature of the device to be charged 20 can be reduced.

[0055] like Figures 1 to 3 As shown, in one embodiment, the wireless charging device 10 includes a housing 100, a first fan 210, a second fan 220, a coil module 300, a first bracket 400, a second bracket 500 and a circuit board 600. The housing 100 includes a first shell 110 and a second shell 120, the first shell 110 and the second shell 120 cover each other to form a receiving space, and the coil module 300, the first bracket 400, the second bracket 500 and the circuit board 600 are all located in the receiving space.

[0056] like Figures 4 to 6 As shown, in one embodiment, the wireless charging device 10 includes a first direction, a second direction and a third direction. The first direction is the length direction, i.e., the Y direction, the second direction is the width direction, i.e., the X direction, and the third direction is the thickness direction, i.e., the Z direction. The first direction is perpendicular to the second direction. The first fan 210 and the second fan 220 are arranged along the length direction, i.e., the Y direction, of the wireless charging device 10, and the coil module 300, the first bracket 400, the second bracket 500 and the circuit board 600 are located between the first fan 210 and the second fan 220, and are arranged along the width direction, i.e., the X direction, of the wireless charging device 10. The housing 100 is provided with an air inlet 215 and an air outlet 225. When the first fan 210 and the second fan 220 are working, the airflow outside the housing 100 is driven to enter the housing 100 from the air inlet 215, and flows through the first fan 210, the device to be charged 20, and the second fan 220, and flows out of the housing 100 from the air outlet 225, and performs heat exchange with the device to be charged 20 and the internal components of the wireless charging device 10, taking away the heat of the device to be charged 20, and taking away the heat inside the wireless charging device 10. The air inlet 215, the first fan 210, the second fan 220 and the air outlet 225 form a heat dissipation duct 30 passing through the device to be charged 20. It can be understood that the number of the air inlet 215 and the air outlet 225 are both multiple, and are evenly arranged at both ends of the length direction of the housing 100, that is, the Y direction. In one embodiment, the first fan 210 and the second fan 220 are both centrifugal fans.

[0057] In another embodiment, when the first fan 210 and the second fan 220 are working, the airflow outside the housing 100 is driven to enter the housing 100 from the air outlet 225, and flows through the second fan 220, the device to be charged 20, and the first fan 210, and flows out of the housing 100 from the air inlet 215, performs heat exchange with the device to be charged 20 and the wireless charging device 10, takes away the heat of the device to be charged 20, and takes away the heat inside the wireless charging device 10.

[0058] In one embodiment, a first vent 214 and a second vent 224 are provided on one side of the housing 100 for carrying the device 20 to be charged. The first vent 214 is connected to the first fan 210, and the second vent 224 is connected to the second fan 220. When the first fan 210 and the second fan 220 are working, the airflow outside the housing 100 is driven to flow through the air inlet 215, the first fan 210, the first vent 214, the device 20 to be charged, the second vent 224, the second fan 220 and the air outlet 225 in sequence. The purpose of opening the first vent 214 and the second vent 224 is to allow the airflow to flow through the device 20 to be charged, so as to take away the heat of the device 20 to be charged and reduce the temperature of the device 20 to be charged. The air inlet 215, the first fan 210, the first vent 214, the second vent 224, the second fan 220 and the air outlet 225 form a heat dissipation duct 30 passing through the device 20 to be charged.

[0059] like Figure 5a , Figure 7 and Figure 8 As shown, in one embodiment, the housing 100 includes a first shell 110 and a second shell 120, and the first shell 110 and the second shell 120 cover each other. The first shell 110 is an open box-like structure, and the second shell 120 is a plate-like structure. It can be understood that the open box-like structure can be a square box or a polygonal box. In this embodiment, the open box-like structure is an open runway-shaped box-like structure, and the second shell 120 covers the first shell 110 to form a storage space. The first shell 110 is used to support the device 20 to be charged, and the first vent 214 and the second vent 224 are located in the first shell 110. In another embodiment, the first shell 110 and the second shell 120 can both be plate-like structures, and the first shell 110 and the second shell 120 are connected by a connecting plate to form a storage space.

[0060] The first housing 110 includes a first plate 111, a second plate 112 and a side plate 113. In the length direction of the wireless charging device 10, i.e., the Y direction, the air inlet 215 and the air outlet 225 are respectively opened at both ends of the side plate 113, the first fan 210 is close to the air inlet 215, and the second fan 220 is close to the air outlet 225. It can be understood that the air inlet 215 and the air outlet 225 may not be located at both ends of the side plate 113, but may be located on one side or both sides of the width direction of the side plate 113, so that the airflow entering the air inlet 215 can enter the first fan 210, and the airflow flowing out of the second fan 220 can flow to the air outlet 225.

[0061] The second plate 112 is covered with the coil module 300, which can be understood as the coil module 300 corresponding to the second plate 112 in the thickness direction of the wireless charging device 10, i.e., the Z direction. When the wireless charging device 10 charges the device to be charged 20, the coil module 300 needs to correspond to the coil inside the device to be charged 20. Since heat is generated when the coil inside the device to be charged 20 and the coil module 300 transmit electrical signals, the coil inside the device to be charged 20 is located at the second plate 112 when the device to be charged 20 is charged. The coil inside the device to be charged 20 needs to correspond to the coil module 300, so the coil module 300 corresponds to the second plate 112 in the Z direction.

[0062] The first plate 111 and the second plate 112 are located on the same side of the side peripheral plate 113. When the wireless charging device 10 is assembled, in the thickness direction of the wireless charging device 10, i.e., the Z direction, the first plate 111 and the second housing 120 are respectively located on opposite sides of the side peripheral plate 113. The first plate 111 is connected to the side peripheral plate 113, and the second plate 112 is recessed relative to the first plate 111, so that there is a height difference between the two, and the height difference is greater than the thickness of the first plate 111, so that there is a gap between the first plate 111 and the second plate 112, so as to form the first vent 214 and the second vent 224.

[0063] like Figure 4 and Figure 7As shown, in one embodiment, in the width direction of the wireless charging device 10, i.e., the X direction, the first plate 111 and the second plate 112 have the same size, i.e., the width of the first plate 111 and the second plate 112 is the same, and both sides of the first plate 111 and the second plate 112, i.e., the ends in the width direction, are connected to the side peripheral plate 113. In the length direction of the wireless charging device 10, i.e., the Y direction, the second plate 112 cuts off the first plate 111, and both ends of the second plate 112 are the first plate 111, and the second plate 112 and the first plate 111 at both ends form a first vent 214 and a second vent 224, respectively. The first vent 214 is close to the first fan 210, and the second vent 224 is close to the second fan 220. It can be understood that the position where the side peripheral plate 113 is connected to the second plate 112 is recessed from the position where the side peripheral plate 113 is connected to the first plate 111.

[0064] In another embodiment, in the width direction of the wireless charging device 10, i.e., the X direction, the size of the second plate 112 is smaller than the size of the first plate 111, i.e., the width of the second plate 112 is smaller than the width of the first plate 111. Specifically, the second plate 112 is formed by the depression of the first plate 111, and the height difference of the depression of the second plate 112 relative to the first plate 111 is greater than the thickness of the first plate 111, so that there is a gap between the second plate 112 and the first plate 111 in the Y direction to form the first vent 214 and the second vent 224. The first vent 214 and the second vent 224 are respectively located at the two ends of the length direction of the second plate 112. Both sides of the second plate 112, i.e., both ends of the second plate 112 in the width direction, are connected to the second plate 112, and are sealed, so that the airflow can only flow along the length direction of the wireless charging device 10, i.e., the Y direction, to prevent the airflow from flowing out from both sides of the second plate 112, i.e., both ends in the width direction, so that the airflow cannot flow according to the designed heat dissipation duct 30.

[0065] In another embodiment, in the width direction of the wireless charging device 10, i.e., the X direction, the size of the second plate 112 is smaller than the size of the first plate 111, i.e., the width of the second plate 112 is smaller than the width of the first plate 111. The second plate 112 is located at the edge of the first plate 111 in the width direction, i.e., the second plate 112 is formed by the concave edge of the first plate 111, and the height difference of the second plate 112 relative to the concave first plate 111 is greater than the thickness of the first plate 111, so that there is a gap between the second plate 112 and the first plate 111 in the Y direction to form the first vent 214 and the second vent 224. The first vent 214 and the second vent 224 are respectively located at the two ends of the length direction of the second plate 112. The two sides of the second plate 112, i.e., the two ends of the second plate 112 in the width direction, are respectively connected to the second plate 112 and the side peripheral plate 113, and are sealed so that the airflow can only flow along the length direction of the wireless charging device 10, i.e., the Y direction, to prevent the airflow from flowing out from the two sides of the second plate 112, i.e., the two ends in the width direction, so that the airflow cannot flow according to the designed heat dissipation duct 30.

[0066] like Figure 5a and Figure 6 As shown, in one embodiment, the first fan 210 and the second fan 220 are both fixed to the first plate 111, and in the length direction of the wireless charging device 10, i.e., the Y direction, the first fan 210 and the second fan 220 are respectively located at the two ends of the second plate 112. The first fan 210 is close to the first vent 214, and the first fan 210 is connected to the first vent 214; the second fan 220 is close to the second vent 224, and the second fan 220 is connected to the second vent 224. There is a first gap 213 between the first fan 210 and the second housing 120, and there is a second gap 223 between the second fan 220 and the second housing 120. The first fan 210 is provided with a first air outlet 211 and a first side air outlet 212, the first air outlet 211 faces the second housing 120, and the first side air outlet 212 faces the first vent 214. The second fan 220 defines a second air port 221 and a second side air port 222 . The second air port 221 faces the second housing 120 , and the second side air port 222 faces the second ventilation port 224 .

[0067] like Figure 3 and Figure 4As shown, in one embodiment, the wireless charging device 10 includes a supporting element 700, and the number of the supporting elements 700 is 2. Two supporting elements 700 are arranged on both sides of the second plate 112, and the two ends of the supporting element 700 are roughly connected to the first plate 111, and the supporting element 700 is roughly flush with the first plate 111. When the wireless charging device 10 is used to charge the charging device 20, the supporting element 700 can support the device to be charged 20. In one embodiment, the supporting element 700 is a strip structure, which is arranged on the second plate 112 and arranged along the length direction of the wireless charging device 10, that is, the Y direction. The two ends of the supporting element 700 are connected to the end of the first plate 111 facing the second plate 112, and the height difference is filled, so that the supporting element 700 is flush with the first plate 111. It can be understood that the supporting element 700 also has the function of windproof. The support element 700 can prevent the airflow flowing out of the first vent 214 from flowing away from there along the width direction of the wireless charging device 10, that is, the X direction, that is, the support element 700 allows the airflow flowing out of the first vent 214 to flow to the second vent 224, so that the trajectory of the airflow conforms to the design of the heat dissipation duct 30. When the device 20 to be charged is placed on the wireless charging device 10, the device 20 to be charged, the two support elements 700 and the first plate 111 form a space, and due to the rotation of the first fan 210 and the second fan 220, the airflow can flow from the first vent 214 to the second vent 224 in the space.

[0068] In another embodiment, the second plate 112 is flush with the first plate 111, and the first vent 214 and the second vent 224 are respectively opened at the two ends of the second plate 112, that is, the first vent 214 and the second vent 224 are respectively provided between the two ends of the second plate 112 and the first plate 111. The first plate 111 is provided with a convex strip, which can be a ring-shaped convex strip, and the first vent 214 and the second vent 224 are located in the area surrounded by the convex strip. The device 20 to be charged is placed on the convex strip when charging. In another embodiment, the number of convex strips is 4, and the 4 convex strips are arranged in a square structure. The first vent 214 and the second vent 224 are located in the area surrounded by the 4 convex strips, and the 4 convex strips can support the device 20 to be charged.

[0069] like Figures 5a to 8As shown, in one embodiment, the first housing 110 includes a first air guide plate 114 and a second air guide plate 115. The first air guide plate 114 and the second air guide plate 115 extend from both ends of the length direction of the second plate 112. The first air guide plate 114 abuts against the end of the first fan 210 facing the first vent 214, and guides all the air flowing out of the first side vent 212 to the first vent 214. The second air guide plate 115 abuts against the end of the second fan 220 facing the second vent 224, and guides all the airflow entering the housing 100 from the second vent 224 to flow to the second side vent 222. In another embodiment, the first air guide plate 114 may also extend to abut against the side of the first fan 210 facing the second housing 120, and the second air guide plate 115 may also extend to abut against the side of the second fan 220 facing the second housing 120.

[0070] like Figure 5a and Figure 6 As shown, in one embodiment, when the first fan 210 and the second fan 220 are working, the external air flow enters the housing 100 through the air inlet 215, flows to the first air outlet 211 through the first gap 213 and enters the first fan 210, flows out of the first fan 210 from the first side air outlet 212, and the air flow out of the first side air outlet 212 flows to the first vent 214 through the guidance of the first air guide plate 114. After the air flow flows out of the first vent 214, it flows through the surface of the device to be charged 20 and enters the housing 100 from the second vent 224. Due to the effect of the second air guide plate 115, the air flow entering the housing 100 from the second vent 224 all flows to the second side air outlet 222, flows through the inside of the second fan 220 and flows out of the fan from the second air outlet 221. Then it flows through the second gap 223 and flows out of the housing 100 from the air outlet 225. When the air flow flows through the first gap 213 and the second gap 223, it can take away the heat of the second housing 120.

[0071] like Figure 5bAs shown, in another embodiment, in the thickness direction of the wireless charging device 10, that is, the third direction, that is, the Z direction, the end of the first air guide plate 114 away from the second plate 112 is located in the first side air outlet 212, and is at a certain distance from both sides of the Z direction of the first side air outlet 212, so that a part of the airflow flowing out of the first fan 210 is guided to the first vent 214 by the first air guide plate 114, and the other part of the airflow flows to the gap between the coil module 300 and the second plate 112, that is, flows through the surface of the coil module 300. In the thickness direction of the wireless charging device 10, i.e., in the Z direction, the end of the second air guide plate 214 away from the second plate 112 is located in the second side air outlet 222, and is at a certain distance from both sides of the second side air outlet 222 in the Z direction, so that the airflow flowing from the first vent 214 to the second vent 224 can be guided by the second air guide plate 214 to the second fan 220, and the airflow in the gap between the coil module 300 and the second plate 112 can flow into the second side air outlet 222. That is, the airflow flowing out of the first fan 210 from the first side air outlet 211 is divided into two streams by the first air guide plate 114, one stream flows through the device to be charged 20, and the other stream flows through the coil module 300. The two streams of airflow return at the second side air outlet 222 through the guidance of the second air guide plate 214, and both enter the second fan 220, thereby taking away the heat of the device to be charged 20 and the coil module 300.

[0072] The heat dissipation duct 30 of the present application is simple in design and has low wind resistance. The first fan 210 and the second fan 220 are used to guide the flow of airflow, and the heat dissipation effect is good. It can well support the needs of high-power wireless charging and shorten the charging time. In addition, the wireless charging device 10 adopts a symmetrical design, which can guide the user to place the device to be charged 20, and the placement angle of the device to be charged 20 is not restricted, thereby improving the user experience. It is understandable that whether the electronic device covers the entire area of ​​the second plate 112 does not affect the heat dissipation effect of the heat dissipation duct 30, that is, the wireless charging device 10 is well compatible with various shapes of devices to be charged 20, and can make the device to be charged 20 dissipate heat well.

[0073] In one embodiment, the first housing 110 is an integrally formed structure, that is, the first plate 111, the second plate 112, the side peripheral plate 113, the first air guide plate 114 and the second air guide plate 115 are an integrally formed structure. The specific molding process may be injection molding, etc., which is not specifically limited here.

[0074] like Figure 4 , Figure 5a and Fig. 9As shown, in one embodiment, the coil module 300 includes a coil 310 and a magnetic isolation sheet 320, the coil 310 is fixed to the side of the magnetic isolation sheet 320 facing the first shell 110, and the side of the magnetic isolation sheet 320 facing away from the coil 310 is fixed to the first bracket 400. The first bracket 400 is a U-shaped bracket, fixed to the second shell 120. It can be understood that the first bracket 400 is not limited to a U-shaped bracket, and can also be a bracket of other shapes, which is not specifically limited here. The first bracket 400 is made of heat-conducting material, such as metal or hardware with good thermal conductivity. The first bracket 400 can transfer the heat generated by the coil module 300 to the second shell 120, and when the airflow flows through the first gap 213 and the second gap 223, it can take away the heat of the second shell 120, so that the heat of the coil module 300 can be taken out of the shell 100. It is understandable that the material of the second shell 120 can be metal or hardware with good thermal conductivity, which makes it convenient for the first bracket 400 to transfer the heat of the coil module 300 to the second shell 120, and also makes it convenient for the airflow in the first gap 213 and the second gap 223 to take away the heat of the second shell 120.

[0075] like Figure 4 , Figure 5a and Fig. 9 As shown, in one embodiment, the second bracket 500 is an open box-shaped structure, such as an open square box-shaped structure, and the opening of the second bracket 500 faces the second shell 120 and is fixed to the second shell 120. The circuit board 600 is fixed in the second bracket 500, and specifically, it can be arranged on the panel of the second bracket 500 facing the second shell 120. The second bracket 500 is made of heat-insulating material to prevent heat transfer between the coil module 300 and the circuit board 600. A mud-like heat-conducting layer with a high thermal conductivity is provided between the circuit board 600 and the second shell 120. The heat-conducting layer is made of heat-conducting material, such as silicone grease, so that the heat of the circuit board 600 is transferred to the second shell 120 through the heat-conducting layer. It can be understood that the side of the circuit board 600 facing the second shell 120 may be a plane or a curved surface, and the side of the second shell 120 facing the circuit board 600 may be a plane or a curved surface. If the circuit board 600 is attached to the second shell 120, the two may not be completely attached, so that the heat transfer efficiency between the two is low. The heat-conducting layer is formed by filling with mud-like heat-conducting material, which increases the contact area and has a high thermal conductivity, so that the heat transfer efficiency between the circuit board 600 and the second shell 120 is high.

[0076] like Fig.10 and Fig.11As shown, in one embodiment, the wireless charging device 10 includes a third bracket 800. A first receiving groove 810 is provided on the outer surface of the second shell 120, and the third bracket 800 is rotatably connected to the second shell 120 through a rotating shaft, and can be accommodated in the first receiving groove 810 or rotated out of the first receiving groove 810. When the third bracket 800 is accommodated in the first receiving groove 810, the third bracket 800 is flush with the outer surface of the second shell 120. When the third bracket 800 is rotated out of the first receiving groove 810, the third bracket 800 can support the housing 100 so that the wireless charging device 10 stands on its side.

[0077] like Figures 12 to 15 As shown, in one embodiment, the wireless charging device 10 includes a fourth bracket 900. The side peripheral plate 113 is provided with a second receiving groove 910, and the fourth bracket 900 is slidably disposed in the second receiving groove 910, and can slide to a first position and a second position relative to the housing 100. In the first position, the fourth bracket 900 is accommodated in the second receiving groove 910 and is flush with the first plate 111. In the second position, at least part of the structure of the fourth bracket 900 is located outside the second receiving groove 910 and protrudes from the first plate 111. It can be understood that a stopper 920 is provided on the fourth bracket 900 to prevent the fourth bracket 900 from being separated from the second receiving groove 910.

[0078] like Fig.13 As shown, when the fourth bracket 900 is in the second position and the third bracket 800 is rotated outside the first receiving groove 810, the wireless charging device 10 is a vertical structure, and the user can stand the mobile phone waiting for charging device 20 on the fourth bracket 900, which is convenient for the user to use, such as watching videos while charging, etc., thereby improving the user experience.

[0079] The wireless charging device 10 of the present application includes a symmetrically designed first fan 210 and a second fan 220, and has a relatively strong wind force. The second plate 112 is designed to be recessed in the first plate 111 to form a first vent 214 and a second vent 224, so that air can flow through the device to be charged 20, thereby helping the device to be charged 20 to dissipate heat.

[0080] The heat of the coil module 300 can be transferred to the second housing 120 through the first bracket 400, the heat of the circuit board 600 can be transferred to the second housing 120 through the heat conductive layer, and the heat of the second housing 120 can be transferred to the outside of the housing 100 through the airflow of the first gap 213 and the second gap 223, so that the wireless charging device 10 itself has a good heat dissipation effect and reduces the impact on the heat dissipation performance of the device to be charged 20. The heat dissipation duct 30 of the wireless charging device 10 is simple in design, has a good heat dissipation effect, and can take away the heat of the device to be charged 20, so that it can well support the needs of high-power wireless charging and shorten the charging time.

[0081] The wireless charging device 10 adopts a symmetrical design, which can well guide the user to place the device to be charged 20, and the placement angle is not restricted, thereby improving the user experience.

[0082] The wireless charging device 10 can stand sideways through the third bracket 800 and the fourth bracket 900, so that the device to be charged 20 can stand sideways when charging, increasing the application scenarios of the device to be charged 20 when charging, such as watching videos while charging.

[0083] 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.

[0084] 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.
