Detailed Description

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

As shown in fig. 1 to 3, in an embodiment, a wireless charging device 10 is provided, in which the wireless charging device 10 has two fans, and a heat dissipation air duct 30 is formed to have a better heat dissipation effect. It is understood that a wireless charging device 10 having multiple fans is also within the scope of the present application. When the wireless charging device 10 charges the to-be-charged device 20, the heat dissipation air duct 30 can reduce the temperature of the wireless charging device 10, and the air flow can flow through the side, facing the wireless charging device 10, of the to-be-charged device 20, so that the temperature of the to-be-charged device 20 can be reduced.

As shown in fig. 1 to 3, in an embodiment, the wireless charging apparatus 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 housing 110 and a second housing 120, the first housing 110 and the second housing 120 cover each other to form an accommodating space, and the coil module 300, the first bracket 400, the second bracket 500, and the circuit board 600 are all located in the accommodating space.

As shown in fig. 4-6, in one embodiment, the wireless charging device 10 includes a first direction, a second direction, and a third direction. The first direction is a longitudinal direction, i.e., a Y direction, the second direction is a width direction, i.e., an X direction, and the third direction is a thickness direction, i.e., a Z direction. The first direction and the second direction are perpendicular. The first fan 210 and the second fan 220 are disposed along a length direction, i.e., a Y direction, of the wireless charging apparatus 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 disposed along a width direction, i.e., an X direction, of the wireless charging apparatus 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 work, the air flow 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 exchanges heat with the internal elements of the device to be charged 20 and the wireless charging device 10, so as to take away the heat of the device to be charged 20 and take 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 air duct 30 passing through the device to be charged 20. It can be understood that the number of the air inlets 215 and the air outlets 225 is plural, and the air inlets and the air outlets are uniformly arranged at both ends of the length direction of the housing 100, i.e., the Y direction. In one embodiment, the first fan 210 and the second fan 220 are both centrifugal fans.

In another embodiment, when the first fan 210 and the second fan 220 operate, the air flow 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, the first fan 210, and flows out of the housing 100 from the air inlet 215, and exchanges heat with the device to be charged 20 and the wireless charging device 10, and carries away heat of the device to be charged 20 and heat inside the wireless charging device 10.

In an embodiment, a first ventilation opening 214 and a second ventilation opening 224 are opened on a side of the housing 100 for carrying the device to be charged 20. The first vent 214 is in communication with the first fan 210 and the second vent 224 is in communication with the second fan 220. When the first fan 210 and the second fan 220 operate, the airflow outside the housing 100 is driven to flow through the air inlet 215, the first fan 210, the first ventilation opening 214, the device to be charged 20, the second ventilation opening 224, the second fan 220, and the air outlet 225 in sequence. The first and second vents 214 and 224 are opened to allow airflow through the device 20 to be charged so as to carry heat away from 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 ventilation opening 214, the second ventilation opening 224, the second fan 220, and the air outlet 225 form the heat dissipation air duct 30 passing through the device to be charged 20.

As shown in fig. 5a, 7 and 8, in one embodiment, the housing 100 includes a first housing 110 and a second housing 120, and the first housing 110 and the second housing 120 are covered with each other. The first housing 110 has an open box-shaped structure, and the second housing 120 has a plate-shaped structure. It can be understood that the open box-shaped structure may be a square box or a polygonal box, in this embodiment, the open box-shaped structure is an open racetrack-shaped box-shaped structure, and the second casing 120 covers the first casing 110 and forms an accommodating space. The first housing 110 is used for supporting the device to be charged 20, and the first ventilation opening 214 and the second ventilation opening 224 are located in the first housing 110. In another embodiment, the first housing 110 and the second housing 120 may be both plate-shaped structures, and the first housing 110 and the second housing 120 are connected by a connecting plate to form an accommodating space.

The first case 110 includes a first plate 111, a second plate 112, and a side peripheral 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 two ends of the side peripheral 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 is understood that the air inlet 215 and the air outlet 225 may be located on one side or both sides of the width direction of the side peripheral plate 113 instead of the two ends of the side peripheral plate 113, so as to enable the air flow entering the air inlet 215 to enter the first fan 210 and the air flow flowing out from the second fan 220 to flow to the air outlet 225.

The second plate 112 covers the coil module 300, and it can be understood that the coil module 300 corresponds 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 20 to be charged, the coil module 300 needs to correspond to the coil inside the device 20 to be charged, and when the coil inside the device 20 to be charged transfers an electrical signal to the coil module 300, heat is generated, so that the coil inside the device 20 to be charged is located on the second board 112. 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.

The first plate 111 and the second plate 112 are located on the same side of the side peripheral plate 113, and in the assembled state of the wireless charging apparatus 10, the first plate 111 and the second case 120 are located on two opposite sides of the side peripheral plate 113 in the thickness direction of the wireless charging apparatus 10, i.e., the Z direction. The first plate 111 is connected to the side peripheral plate 113, and the second plate 112 is recessed with respect to the first plate 111 such that a height difference exists therebetween, and the height difference is greater than the thickness of the first plate 111 such that a gap exists between the first plate 111 and the second plate 112 to form the first ventilation opening 214 and the second ventilation opening 224.

As shown in fig. 4 and 7, 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 width of the second plate 112 are the same, and both sides, i.e., the ends in the width direction, of the first plate 111 and the second plate 112 are connected to the side peripheral plate 113. In the length direction of the wireless charging device 10, that is, the Y direction, the second plate 112 cuts off the first plate 111, and both ends of the second plate 112 are the first plates 111, and the second plate 112 and the first plates 111 at both ends form the first ventilation opening 214 and the second ventilation opening 224, respectively. The first ventilation opening 214 is adjacent to the first fan 210 and the second ventilation opening 224 is adjacent to the second fan 220. It will be appreciated that the location of the side peripheral panel 113 where it is attached to the second panel 112 is recessed from the location of the side peripheral panel 113 where it is attached to the first panel 111.

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. In particular, the second plate 112 is formed by the first plate 111 being recessed, and the height difference of the second plate 112 with respect to the first plate 111 being greater than the thickness of the first plate 111, so that a gap exists between the second plate 112 and the first plate 111 in the Y direction to form the first ventilation opening 214 and the second ventilation opening 224. The first and second ventilation openings 214 and 224 are located at both ends of the second plate 112 in the longitudinal direction, respectively. Both sides of second board 112, that is, both ends of the width direction of second board 112 are all connected to second board 112, and are sealing connection for the air current only can flow along the length direction of wireless charging device 10, that is, the Y direction, avoids the air current to flow from both sides of second board 112, that is, both ends of width direction, and makes the air current can not flow according to the heat dissipation wind channel 30 of design.

In still 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, that is, the second plate 112 is formed by recessing the edge of the first plate 111, and the height difference of the recess of the second plate 112 with respect to the first plate 111 is greater than the thickness of the first plate 111, so that a gap exists between the second plate 112 and the first plate 111 in the Y direction to form the first ventilation opening 214 and the second ventilation opening 224. The first and second ventilation openings 214 and 224 are located at both ends of the second plate 112 in the longitudinal direction, respectively. The two sides of the second plate 112, that is, the two ends in the width direction of the second plate 112, are connected to the second plate 112 and the side peripheral plate 113 respectively, and are in sealed connection, so that the airflow can only flow along the length direction, that is, the Y direction, of the wireless charging device 10, and the airflow is prevented from flowing out from the two sides, that is, the two ends in the width direction, of the second plate 112, so that the airflow cannot flow according to the designed heat dissipation air duct 30.

As shown in fig. 5a and 6, in an embodiment, the first fan 210 and the second fan 220 are fixed on the first board 111, and the first fan 210 and the second fan 220 are respectively located at two ends of the second board 112 in a length direction, i.e., a Y direction, of the wireless charging device 10. The first fan 210 is close to the first vent 214, and the first fan 210 is communicated with the first vent 214; the second fan 220 is adjacent to the second ventilation opening 224, and the second fan 220 is in communication with the second ventilation opening 224. A first gap 213 exists between the first fan 210 and the second housing 120, and a second gap 223 exists between the second fan 220 and the second housing 120. The first fan 210 has a first air opening 211 and a first side air opening 212, the first air opening 211 faces the second housing 120, and the first side air opening 212 faces the first air vent 214. The second fan 220 has a second air opening 221 and a second side air opening 222, the second air opening 221 faces the second housing 120, and the second side air opening 222 faces the second ventilation opening 224.

As shown in fig. 3 and 4, in one embodiment, the wireless charging device 10 includes 2 support members 700, the number of the support members 700 being 2. The 2 supporting members 700 are disposed on two sides of the second plate 112, two ends of the supporting members 700 are approximately abutted against the first plate 111, and the supporting members 700 are approximately flush with the first plate 111. When the wireless charging apparatus 10 is used to charge the charging apparatus 20, the supporting member 700 may support the charging apparatus 20. In one embodiment, the supporting element 700 is a strip-shaped structure, disposed on the second plate 112, and disposed along the length direction, i.e., the Y direction, of the wireless charging device 10. The two ends of the support member 700 abut the end of the first plate 111 facing the second plate 112 and level the difference in height so that the support member 700 is flush with the first plate 111. It will be appreciated that the support member 700 also has a wind-blocking effect. The supporting member 700 can prevent the airflow flowing out from the first ventilation opening 214 from flowing away from the wireless charging device 10 along the width direction, i.e. the X direction, i.e. the supporting member 700 makes the airflow flowing out from the first ventilation opening 214 flow to the second ventilation opening 224, so that the trajectory of the airflow conforms to the design of the heat dissipation air duct 30. When the device to be charged 20 is placed in the wireless charging device 10, the device to be charged 20, the 2 support members 700, and the first plate 111 form a space in which an air flow can flow from the first ventilation opening 214 to the second ventilation opening 224 due to the rotation of the first fan 210 and the second fan 220.

In another embodiment, the second plate 112 is flush with the first plate 111, and the first ventilation opening 214 and the second ventilation opening 224 are respectively opened at two ends of the second plate 112, i.e. the first ventilation opening 214 and the second ventilation opening 224 are respectively arranged between two ends of the second plate 112 and the first plate 111. The first plate 111 is provided with a convex strip, which may be an annular convex strip, and the first ventilation opening 214 and the second ventilation opening 224 are located in an area surrounded by the convex strip. And the charging device 20 is arranged on the convex strip when being charged. In another embodiment, the number of the convex strips is 4, 4 convex strips are surrounded to form a square structure, the first ventilation opening 214 and the second ventilation opening 224 are located in the region surrounded by 4 convex strips, and the 4 convex strips can support the to-be-charged device 20.

As shown in fig. 5a to 8, in an embodiment, the first casing 110 includes a first wind deflector 114 and a second wind deflector 115. The first air guiding plate 114 and the second air guiding plate 115 extend from both ends of the second plate 112 in the length direction. The first air deflector 114 abuts against an end of the first fan 210 facing the first vent 214, and guides the entire flow flowing out of the first side vent 212 to the first vent 214. The second air deflector 115 abuts against the end of the second fan 220 facing the second ventilation opening 224, and guides the air flow entering the casing 100 from the second ventilation opening 224 to flow to the second side ventilation opening 222. In another embodiment, the first wind deflector 114 may also extend to abut against the side of the first fan 210 facing the second casing 120, and the second wind deflector 115 may also extend to abut against the side of the second fan 220 facing the second casing 120.

As shown in fig. 5a and fig. 6, in an embodiment, when the first fan 210 and the second fan 220 operate, the external air flow enters the inside of the casing 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 is guided by the first air deflector 114, so that the air flow flowing out of the first side air outlet 212 completely flows to the first air outlet 214. The airflow exits the first vent 214, flows over the surface of the device 20 to be charged, and enters the housing 100 through the second vent 224. Due to the second air deflector 115, the air flow entering the casing 100 from the second ventilation opening 224 flows to the second side ventilation opening 222, flows through the inside of the second fan 220 and flows out of the fan from the second ventilation opening 221. And then flows through the second gap 223 and flows out of the housing 100 through the outlet 225. The air flow can take away heat of the second housing 120 while passing through the first gap 213 and the second gap 223.

As shown in fig. 5b, in another embodiment, in the thickness direction of the wireless charging device 10, i.e., the third direction, i.e., the Z direction, an end of the first air deflector 114 away from the second plate 112 is located in the first side air opening 212, and both sides of the first side air opening 212 in the Z direction are spaced apart, so that a part of the airflow flowing out of the first fan 210 is guided to the first air opening 214 by the first air deflector 114, and another part of the airflow flows to the gap between the coil module 300 and the second plate 112, i.e., flows through the surface of the coil module 300.
