[0046] An embodiment of the present application provides a vehicle-mounted wireless charging device. In practical applications, the vehicle-mounted wireless charging device is installed on a vehicle and is used to wirelessly charge electronic devices.

[0047] Reference Figure 1 A schematic diagram of a disassembled state of a vehicle-mounted wireless charging device according to an embodiment of the present application is shown. Figure 2 , a schematic diagram of an assembly state of a vehicle-mounted wireless charging device according to an embodiment of the present application. Specifically, the vehicle-mounted wireless charging device may include: a wireless charging module 1; a cooling pipeline 2; and a heat exchange device 3, wherein the heat exchange device 3 is connected to the wireless charging module 1 and communicates with the cooling pipeline 2.

[0048] In the embodiment of the present application, the wireless charging module 1 is used to wirelessly charge the electronic device, the cooling pipe 2 is used to access the cooling medium from the vehicle air conditioning system, and the heat exchange device 3 is used to exchange heat with the cooling medium to dissipate heat from the wireless charging module 1. Specifically, the heat exchange device 3 is a heat exchanger 3.

[0049] Specifically, the cooling medium is a refrigerant connected from the vehicle air-conditioning system pipeline, and the heat exchanger 3 is an evaporator. The refrigerant is a working fluid that transfers heat energy in the air-conditioning system to produce a refrigeration effect. The temperature inside the vehicle is adjusted by the refrigerant undergoing three-state changes in the vehicle air-conditioning system. In the embodiment of the present application, by connecting the heat exchange device 3 to the wireless charging module 1, the refrigerant connected from the cooling pipeline 2 is passed into the heat exchange device 3, and evaporates from liquid to gas in the heat exchange device 3. The evaporation absorbs heat, which can take away the heat of the wireless charging module 1, so that the wireless charging module 1 dissipates heat. The heat dissipation capacity is high through phase change, thereby improving the heat dissipation efficiency of the wireless charging module 1.

[0050] Reference Figure 1 Optionally, the vehicle-mounted wireless charging device further includes: an expansion valve 4 , which is arranged in the cooling pipeline 2 .

[0051] In the embodiment of the present application, the expansion valve 4 is used to adjust the flow rate of the cooling medium. By setting the expansion valve 4 in the cooling pipeline 2, on the one hand, the flow rate of the cooling medium can be controlled to adjust the heat dissipation effect of the vehicle-mounted wireless charging device. On the other hand, the throttling effect of the expansion valve 4 can create conditions for the evaporation of the cooling medium and improve the heat dissipation effect of the wireless charging module 1.

[0052] Reference Figure 1 Optionally, the wireless charging module 1 includes: a placement plate 10, a bracket 11 and a wireless charging module 12; the bracket 11 includes a first side and a second side that are set away from each other; the wireless charging module 12 is connected to the second side and is connected to the heat exchange device 3.

[0053] In practical applications, the bracket 11 includes a first side and a second side that are set apart; the wireless charging module 12 is fixedly connected to the second side, and the wireless charging module 12 may include a PCB board, a coil and a cover. The inner cavity of the cover is provided with a PCB board and a receiving coil, and the cover is fixedly connected to the bracket 11 to prevent the electronic components from being exposed to the outside and improve safety performance. In addition, an airflow channel is provided at the bottom of the cover, and heat is exchanged with the heat exchange device 3 through the gap of the airflow channel, thereby cooling the PCB board and the coil.

[0054] Reference Figure 3 FIG. 1 shows another schematic diagram of the assembly state of a vehicle-mounted wireless charging device according to an embodiment of the present application. Figure 4 , a schematic diagram of another in-vehicle wireless charging device in a disassembled state according to an embodiment of the present application. Optionally, the in-vehicle wireless charging device further includes: a heat spreader 6, the wireless charging module 1 further includes a placement plate 10, the placement plate 10 is connected to the first side of the bracket 11; the heat spreader 6 is disposed between the placement plate 10 and the wireless charging module 13.

[0055] Specifically, the placement board 10 is used to place electronic devices; the placement board 10 is a groove-shaped structure with a concave cavity, on which electronic devices can be placed, and has side walls and a bottom surface. It should be understood that the side walls or bottom surfaces may be non-continuous planes. Exemplarily, the side walls or bottom surfaces may be provided with one or more openings. The shape of the placement board 10 may be any suitable shape suitable for accommodating electronic devices, including but not limited to a cuboid, a cube, a cylinder or other irregular shapes.

[0056] Specifically, the heat spreader 6 is a vacuum cavity with a microstructure on the inner wall, usually made of copper. When heat is conducted from the heat source to the evaporation zone, the coolant in the cavity begins to vaporize after being heated in a low vacuum environment. At this time, it absorbs heat energy and expands rapidly in volume. The gas phase cooling medium quickly fills the entire cavity. When the gas phase medium contacts a relatively cold area, condensation will occur. The accumulated heat during evaporation is released by the condensation phenomenon, and the condensed coolant will return to the evaporation heat source through the microstructured capillary channel. This operation will be repeated in the cavity.

[0057] In actual applications, by setting up a heat spreader 6, the heat generated by the placement plate 10 can be transferred to the wireless charging module 12 through the function of conducting the heat out after the heat spreader 6 itself is heated, so as to balance the heat of the wireless charging module 1, and at the same time, heat is exchanged through the heat exchange device 3. Since the heat spreader 6 is a common structure, heat is exchanged through the heat spreader 6 and the heat exchange device 3, making the structure of the vehicle-mounted wireless charging device simpler.

[0058] Reference Figure 5 , shows a schematic diagram of the decomposition of another vehicle-mounted wireless charging device structure in an embodiment of the present application. Optionally, the heat exchange device 3 includes two, one of the heat exchange devices 3 is connected to the placement plate 10, and the other heat exchange device 3 is connected to the wireless charging module 12.

[0059] In the embodiment of the present application, two heat exchange devices 3 are used to exchange heat with the placement plate 10 and the wireless charging module 12 respectively, and heat is dissipated point by point, thereby further improving the heat dissipation efficiency of the vehicle-mounted wireless charging device.

[0060] Reference Figure 1 Optionally, the vehicle-mounted wireless charging device further includes an air deflector 5 , and the wireless charging module 1 further includes the placement plate 10 , and the air deflector 5 is connected to the bracket 11 .

[0061] In practical applications, the air guide plate 5 is slidably connected to the bracket 11. The air guide plate 5 may be a flat plate structure with an inclined edge. The air guide plate 5 may slide out from the guide rail of the bracket 11. The inclined edge may stably overlap the air outlet of the vehicle air conditioning system, and guide the cold air at the air outlet to the placement plate 10, and the placement plate 10 is cooled by the cold air. While the heat exchange device 3 is cooling the wireless charging module 1, the placement plate 10 can be cooled by the cold air, thereby improving the heat dissipation capability of the vehicle-mounted wireless charging device.

[0062] Reference Figure 6 , shows a schematic diagram of the principle of another vehicle-mounted wireless charging device structure in the embodiment of the present application, referring to Figure 7, shows a schematic diagram of the principle of another vehicle-mounted wireless charging device structure in an embodiment of the present application. Optionally, the expansion valve 4 is an electronic expansion valve 4, and the vehicle-mounted wireless charging device also includes: a temperature detection device 9 and a control device 40; the temperature detection device 9 is installed on the wireless charging module 1; the control device 40 is electrically connected to the temperature detection device 9 and the electronic expansion valve 4, respectively.

[0063] In the embodiment of the present application, the temperature detection device 9 is installed on the wireless charging module 1. The temperature detection device 9 can be a temperature sensor. The temperature of the wireless charging module 1 is detected by the temperature sensor and sent to the control device 40 in real time. The control device 40 is integrated in the vehicle controller, and controls the opening of the electronic expansion valve 4 by receiving the temperature of the wireless charging module 1 to adjust the flow of the cooling medium, thereby adjusting the heat dissipation of the heat exchange device, realizing dynamic adjustment of the heat dissipation effect of the vehicle-mounted wireless charging device, and can accurately dissipate heat according to the actual heat generation.

[0064] Reference Figure 8 , a schematic diagram showing the principle of the control device 40 controlling the electronic expansion valve 4 in an embodiment of the present application is shown. Specifically, in the present application, the real-time temperature detected by the temperature detection device 9 is judged against the current mode, and the control device 40 calculates the difference between the implementation temperature and the preset temperature of the current mode to control the opening of the electronic expansion valve 4 to adjust the flow rate of the cooling medium to control the amount of heat dissipation.

[0065] Exemplarily, when the wireless charging module 1 is turned off, the control device 40 controls the opening of the electronic expansion valve 4 to be 0, and the electronic expansion valve 4 is closed. At this time, there is no cooling medium in the heat exchange device 3, and the wireless charging module 1 does not dissipate heat.

[0066] When the wireless charging module 1 is turned on, the cooling mode of the vehicle-mounted wireless charging device can be divided into two types: extreme cooling and intelligent cooling. The preset temperature of the extreme cooling mode is T1, and the temperature of the intelligent cooling mode is T2. The unit of temperature is ℃.

[0067] In the extreme cooling mode, the control device 40 calculates the difference between the preset temperature T1 and the collected temperature T. When T>T1+5, the opening of the electronic expansion valve 4 is 100% for extreme cooling and heat dissipation. When T<T1-5, the opening of the electronic expansion valve is 0.

[0068] In the intelligent cooling mode, the opening of the electronic expansion valve 4 can be divided into 5 gears, namely 1-25%-50%-75%-100%. The control device 40 will calculate the difference between the preset temperature T2 and the collected temperature T and adjust the gear: if T<T2-5, the opening of the electronic expansion valve 4 is 0; if T2-5≤T<T2, the opening of the electronic expansion valve 4 is 25%; if T2≤T<T2+5, the opening is adjusted to 50%; if T2+5≤T<T2+10, the opening of the electronic expansion valve 4 is up to 75%; if T2+10≤T, the opening of the electronic expansion valve 4 is up to 100%. After each adjustment of the opening of the electronic expansion valve 4, the temperature will be continuously detected for not less than 2 minutes before the next adjustment of the electronic expansion valve 4 is made, so that the cooling mode can be adjusted according to the temperature of the wireless charging module 1 after adjustment.

[0069] Reference Figure 1 - Figure 4 as well as Figure 7 , a vehicle-mounted wireless charging device with one structure and a vehicle-mounted wireless charging device with another structure in an embodiment of the present application are shown.

[0070] In actual applications, the temperature detection device 9 can be set at any position on the placement plate 10 to detect the temperature of the wireless charging module 1 and send it to the control device 40 to control the opening of the electronic expansion valve 4 through the received temperature of the wireless charging module 1 to adjust the flow rate of the cooling medium, thereby adjusting the heat dissipation of the heat exchange device 3, thereby dynamically adjusting the heat dissipation effect of the vehicle-mounted wireless charging device, and being able to accurately dissipate heat according to the actual heat generation.

[0071] Reference Figure 5 as well as Figure 6 In the embodiment of the present application shown in FIG. 1 , another structure of a vehicle-mounted wireless charging device, optionally, the temperature detection device 9 includes two temperature detection devices 9 , one temperature detection device 9 is installed on the placement plate 10 , and the other temperature detection device 9 is installed on the wireless charging module 12 .

[0072] In an embodiment of the present application, the temperature detection device 9 can be set at any position of the placement plate 10 and the wireless charging module 12 to control the opening of the electronic expansion valve 4 by receiving the temperature of the placement plate 10 and the wireless charging module 12, so as to adjust the flow rate of the cooling medium, thereby adjusting the heat dissipation of each heat exchange device 3, thereby dynamically adjusting the heat dissipation effect of the vehicle-mounted wireless charging device, and being able to perform more accurate heat dissipation according to the actual heat generation of the placement plate 10 and the wireless charging module 12.

[0073] Reference Figure 1 Optionally, the vehicle-mounted wireless charging device further includes: a water accumulation shell 7 , which is connected to the heat exchange device 3 ; and a drain pipe 8 , which is connected to the water accumulation shell 7 .

[0074] In actual applications, when the cooling medium evaporates in the heat exchange device 3, the heat exchange device 3 will generate condensed water. By installing the water collection shell 7 on the heat exchange device 3, the condensed water generated by the heat exchange device 3 is collected and discharged outside the vehicle through the drain pipe 8, thereby preventing the condensed water from dripping into the vehicle, breeding mold, generating odor, and polluting other parts in the vehicle.
