Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1, a wireless charging apparatus 10 is provided in an embodiment of the present utility model. The wireless charging device 10 includes, for example, a housing 100, a coil module 200, and a heat dissipation structure 300. The wireless charging device is used for charging electronic equipment such as a mobile phone, a tablet and the like.

Specifically, the housing 100 includes, for example, a first housing 110, and the first housing 110 is used to connect to an external electronic device. The coil module 200 is disposed in the housing 100, for example, and the coil module 200 is used for charging an external electronic device. The heat dissipation structure 300 is disposed in the housing 100, for example, and the heat dissipation structure 300 is disposed near the first housing 110 and the coil module 200 at the same time, and a heat dissipation channel for dissipating heat from the coil module 200 and the external electronic device is formed between the heat dissipation structure 300 and the housing 100.

The housing 100 is, for example, a casing of the wireless charging device 10, and the housing 100 includes, for example, a first housing 110, where the first housing 110 is used for connecting an external electronic device to charge the external electronic device, and the housing 100 provides protection and support functions. The coil module 200 is disposed in the housing 100, for example, and is used for wirelessly charging an external electronic device, the coil module 200 generally generates heat during operation, and if the heat cannot be timely led out, the charging power is reduced when the temperature reaches a preset safety threshold, so as to affect the charging efficiency of the wireless charging device 10. The heat dissipation structure 300 is disposed near the first housing 110 and the coil module 200, and the heat dissipation structure 300 is used for simultaneously dissipating heat from the coil module 200 and the external electronic device, so that heat generated by the coil module 200 and the external electronic device can be effectively discharged by absorbing heat from two sides and then dissipating the heat, thereby preventing overheating.

In the present embodiment, by disposing the heat dissipation structure 300 in the housing 100 and disposing the heat dissipation structure 300 close to the first housing 110 and the coil module 200, heat dissipation can be effectively performed. The heat dissipation structure 300 can rapidly discharge the generated heat through a reasonably designed heat dissipation channel or other heat dissipation modes. Therefore, the safety mechanism for reducing the charging power is triggered by delaying or even preventing the temperature of the equipment from reaching the set safety threshold when the equipment works, so that the heat dissipation efficiency of the charging device is improved, the overheat phenomenon can be effectively prevented, and the charging efficiency and safety are ensured.

For example, when a user places a mobile phone on the wireless charging device 10 to charge, the coil module 200 of the wireless charging device 10 starts to operate, and generates an electromagnetic field to perform wireless charging, and at the same time generates a certain amount of heat. In this case, the heat dissipation structure 300 is located close to the coil module 200 and the mobile phone, rapidly dissipates heat through the heat dissipation channel, and maintains the heat dissipation effect of the device. Therefore, in the process of charging the electronic equipment, the heat dissipation efficiency can be improved, and the overheat phenomenon is avoided, so that the charging efficiency and the safety are maintained.

Referring to fig. 2 and 3, the heat dissipation structure 300 includes, for example, a heat conductive member 310, a heat sink 320, and a fan assembly 330.

Specifically, the heat conducting member 310 is in contact with the first housing 110, for example, and the heat conducting member 310 is disposed close to the coil module 200. The heat sink 320 is disposed, for example, at a side of the heat conductive member 310 remote from the first housing 110. The fan assembly 330 is disposed, for example, on a side of the heat conductive member 310 away from the first housing 110, and the fan assembly 330 is disposed near the heat sink 320.

The heat conducting member 310 is made of, for example, VC temperature uniformity plate, copper aluminum, graphene, or metal material, etc., and is used to transfer generated heat from the coil module 200 to the heat sink 320. The heat sink 320 is made of a metal material, such as aluminum or copper, and the surface of the heat sink 320 is provided with an uneven heat dissipation surface to increase the heat exchange area with air, which has a high heat conduction performance, and the heat sink 320 is used for dissipating the heat conducted by the heat conducting member 310 to the surrounding environment, so as to achieve a heat dissipation effect. The fan assembly 330, for example, is comprised of a motor and fan blades, may generate an airflow. The fan assembly 330 is used for increasing the air cooling effect of the surface of the radiator 320 by generating air flow, thereby further improving the heat dissipation efficiency. The fan assembly 330 is spaced apart from the radiator 320 to ensure the normal flow of the air current. In the present embodiment, the heat conducting member 310 transfers the generated heat from the coil module 200 to the heat sink 320, the heat sink 320 increases the heat dissipation effect by the metal material and the heat dissipation surface, and the fan assembly 330 further improves the heat dissipation efficiency by generating the air flow. In the present embodiment, the fan assembly 330 is, for example, a centrifugal fan device.

Through the above arrangement, the heat dissipation efficiency of the wireless charging device 10 can be effectively improved. When the wireless charging device 10 is in operation, the heat conducting member 310 transfers the generated heat to the heat sink 320, and radiates the heat to the surrounding environment through the heat dissipation surface of the heat sink 320, and at the same time, the fan assembly 330 blows the heat on the coil module 200 and the heat sink 320 out of the wireless charging device 10 in a suction manner. In this way, the heat dissipation efficiency of the wireless charging device 10 is improved, the overheat phenomenon can be effectively prevented, and the charging efficiency and the charging safety are ensured.

For example, when a user places an electronic device such as a mobile phone on the wireless charging device 10 to charge, the coil module 200 of the wireless charging device 10 starts to operate and generates a certain amount of heat, in this case, the heat conducting member 310 transfers the heat of the electronic device such as the mobile phone to the heat sink 320 through the first housing 110, and the heat is dissipated to the surrounding environment through the heat sink 320. Meanwhile, the air flow generated by the fan assembly 330 can accelerate the heat dissipation, thereby further improving the heat dissipation efficiency. In this way, in the process of charging the mobile phone, the heat dissipation efficiency can be improved, the overheat phenomenon can be prevented, and meanwhile, the charging efficiency and the safety of the wireless charging device 10 can be maintained.

Specifically, the heat dissipation channel includes, for example, a first air inlet 101, a second air inlet 321, a third air inlet 331, a first air outlet 102, a second air outlet 322, and a third air outlet 332. Referring to fig. 2, 3, 4 and 5, a first air inlet 101 and a first air outlet 102 are provided on the housing 100, a second air inlet 321 and a second air outlet 322 are provided on the radiator 320, a third air inlet 331 is provided on a side of the fan assembly 330 close to the radiator 320, and a third air outlet 332 is provided on a side of the fan assembly 330 close to the first air outlet 102.

The first air inlet 101 is used for introducing external fresh air into the housing 100, and supplying the fresh air to the radiator 320 and the fan assembly 330 for radiating heat. The first air outlet 102 is used for discharging the heat-radiated hot air out of the casing 100 to maintain the normal operating temperature of the device. The second air inlet 321 is located on the radiator 320 and is used for introducing a part of cooling air to help reduce the temperature of the radiator 320. The second air outlet 322 is located on the radiator 320 and is used for discharging hot air after heat dissipation by the radiator 320 so as to maintain the working effect of the radiator 320. The third air inlet 331 is located on a side of the fan assembly 330 near the radiator 320, and is used for introducing cooling air to help reduce the temperature of the hot air in the housing 100. The third air outlet 332 is located at a side of the fan assembly 330 near the first air outlet 102, and is used for discharging the hot air after the heat dissipation of the fan assembly 330. Of course, in other embodiments, the positions of the air inlet and the air outlet can be changed according to the design requirement of the device, and by reasonably setting the air inlet and the air outlet, the heat dissipation effect of the wireless charging device 10 can be enhanced, and the stability and the reliability of the wireless charging device 10 are improved, which is not limited in this embodiment.

Further, the first air inlet 101, the second air inlet 321, the second air outlet 322, the third air inlet 331, the third air outlet 332 and the first air outlet 102 are sequentially communicated. The external fresh air is introduced into the housing 100 through the first air inlet 101, then helps to reduce the temperature of the radiator 320 through the second air inlet 321, then discharges the hot air cooled by the radiator 320 through the second air outlet 322, the third air inlet 331 introduces the air discharged by the second air outlet 322 and part of the external fresh air, helps to reduce the temperature of the hot air in the housing 100, then discharges the hot air cooled by the fan assembly 330 through the third air outlet 332, and finally discharges the cooled hot air out of the housing 100 through the first air outlet 102 so as to maintain the normal working temperature of the equipment.

In one embodiment of the present utility model, the coil module 200 is disposed, for example, at a side of the heat conductive member 310 remote from the first housing 110. The technical means that the coil module 200 is disposed on the side of the heat conductive member 310 near the first housing 110 can provide better heat transfer effect. When the coil module 200 is close to the first housing 110, the heat conducting member 310 can better conduct heat to the first housing 110, thereby promoting the heat dissipation effect. This effectively reduces the temperature of the wireless charging device 10 and improves the heat dissipation performance of the entire device. In another embodiment of the present utility model, the coil module 200 is disposed at a side of the heat conductive member 310 near the first housing 110. When the coil module 200 is far away from the first housing 110, the heat conducting member 310 can insulate better, so as to reduce the possibility of heat conduction to the first housing 110, thus improving the efficiency and stability of the wireless charging device 10 and avoiding the influence of heat on other elements.

In another embodiment of the present utility model, referring to fig. 4, the heat conducting member 310 is provided with a first through hole 311, and the coil module 200 is disposed in the first through hole 311. In this embodiment, the wireless charging device 10 can be significantly reduced in thickness by forming the first through hole 311 in the heat conductive member 310 and placing the coil module 200 therein. Reducing the thickness of the wireless charging device 10 may increase portability of the wireless charging device 10, further enhancing user experience.

When the heat conducting member 310 is made of metal, the heat conducting member 310 is provided with a through hole corresponding to the coil module 200. The heat conductive member 310 made of metal can efficiently conduct and distribute heat, thereby maintaining the normal operating temperature of the element. In electronic devices, such as radio, communication or power modules, coils are often used to generate magnetic fields or to perform electromagnetic induction, and the coils themselves generate electromagnetic fields, so that if the heat conducting member 310 is too close to the coil module 200, the magnetic fields of the coil module 200 are disturbed, thereby affecting the performance or stability of the device. Therefore, the avoiding through holes in the heat conducting member 310 avoid the coil module 200, so that electromagnetic interference of the heat conducting member 310 to the coil module 200 can be reduced or eliminated, and normal operation of the device is ensured.

Referring to fig. 3, the wireless charging device 10 further includes, for example, a support 400, a battery 900, and a magnetic attraction 800. The magnetic attraction member 800 is, for example, a ring magnet shown in fig. 3, and is used for magnetically attracting external electronic equipment, so as to prevent the electronic equipment from shaking or falling during charging, and improve the reliability of the device. The battery 900 is used to power the coil module 200, the fan assembly 330, and the like. The support 400 is disposed in the housing 100, for example, the support 400 is provided with a second through hole 410, the heat sink 320 is disposed near the second through hole 410, the support 400 is provided with a placement portion 420, and the coil module 200 is disposed on the placement portion 420. In this way, the space in the housing 100 can be effectively utilized, so that the structure of the inside of the wireless charging device 10 is more compact on a rational basis.

The barrier 600 is disposed in the receiving chamber 500 to divide the receiving chamber 500 into a first chamber 510 and a second chamber 520, thus achieving spatial separation and disposing the radiator 320 and the fan assembly 330 in the first chamber 510. In this embodiment, by placing the radiator 320 and the fan assembly 330 in the first cavity 510, the blocking member 600 is connected with the supporting member 400, and forms an air channel with the second housing 120, so that more effective air suction can be achieved, the heat dissipation effect can be improved, the working temperatures of the wireless charging device 10 and the external electronic device can be effectively reduced, and the charging efficiency and the service life of the device can be improved. In other embodiments, the blocking member 600 may be connected to a side of the first housing 110 near the heat sink 320, or the blocking member 600 may be integrally formed with the supporting member 400 and extend along a direction of the supporting member 400 away from the first housing 110, and a position of the blocking member 600 may be adjusted according to an actual structure of the wireless charging device 10, which is not limited herein.
