Description

Technical Field

[0001] This invention relates to the field of vehicle accessories technology. More specifically, this invention relates to in-vehicle wireless charging devices. Background Technology

[0002] Currently, many vehicles are equipped with wireless charging devices to provide wireless charging for electronic devices such as mobile phones. Wireless charging devices transfer energy through electromagnetic induction, and energy loss during this process is dissipated as heat. In particular, during high-power charging modes such as fast charging, wireless charging devices can generate significant heat. If the temperature becomes too high, charging efficiency will decrease or the phone will trigger its overheat protection mechanism.

[0003] Therefore, wireless charging devices on the market are usually equipped with cooling modules. However, traditional cooling modules have slow heat dissipation due to their cast back cover, and the temperature of the air output from the fan also increases with charging time, resulting in poor cooling performance. Some wireless charging devices are equipped with Peltier chip components, which leads to a significant increase in cost, and the cooling capacity of Peltier chip components is relatively weak, resulting in poor cooling effect. Summary of the Invention

[0004] The purpose of this invention is to provide an improved in-vehicle wireless charging device to overcome at least one deficiency in the prior art. More specifically, the in-vehicle wireless charging device according to the present invention has excellent heat dissipation capabilities during high-power charging, thus ensuring charging efficiency and charging speed.

[0005] To this end, the present invention provides an in-vehicle wireless charging device, comprising: a panel adapted to hold an electronic device; a charging module disposed below the panel to wirelessly charge the electronic device; a first cooling plate disposed below the charging module and having a flow channel for cooling the charging module by a refrigerant flowing in the flow channel; and a gas driving unit disposed below the first cooling plate and including a housing and a first gas driving component, the housing and the panel jointly defining an air duct communicating with the upper part of the panel for cooling the electronic device by gas driven by the first gas driving component and flowing through the air duct.

[0006] Based on the above-described technical concept, the present invention may further include any one or more of the following optional forms.

[0007] In some alternative forms, the flow channel includes an inlet end and an outlet end, and the vehicle-mounted wireless charging device further includes a compressor assembly and a piping assembly. The piping assembly includes a first inlet pipe and a first outlet pipe, wherein the compressor assembly is connected to the inlet end through the first inlet pipe and to the outlet end through the first outlet pipe, so as to form a first cooling circuit together with the first inlet pipe, the first cooling plate and the first outlet pipe.

[0008] In some alternative configurations, the inlet and outlet are disposed adjacent to each other, and the piping assembly further includes a pipe connector connected to one end of each of the first inlet and the first outlet pipes, the pipe connector being inserted into the first cooling plate to connect the first inlet pipe to the inlet and the first outlet pipe to the outlet.

[0009] In some alternative forms, the flow channel includes a supply flow channel and a plurality of branch flow channels disposed downstream of the supply flow channel. The supply flow channel is connected to the first inlet pipe through the liquid inlet end. The plurality of branch flow channels are evenly distributed and extend in a curved manner within the first cooling plate, and each of the plurality of branch flow channels is connected to the corresponding first outlet pipe through a corresponding liquid outlet end.

[0010] In some alternative configurations, the piping assembly further includes a second inlet pipe and a second outlet pipe, and the compressor assembly is connected to a second cooling plate suitable for a vehicle refrigerator via the second inlet pipe and the second outlet pipe, so as to form a second cooling circuit together with the second inlet pipe, the second cooling plate and the second outlet pipe.

[0011] In some alternative configurations, the piping assembly further includes a control valve located downstream of the compressor assembly and connected to the first and second inlet pipes to enable the first and second cooling circuits to operate simultaneously or individually by controlling the refrigerant flow into the first and second inlet pipes.

[0012] In some alternative forms, the vehicle-mounted wireless charging device further includes a first heat dissipation fin, which is disposed within the air duct and fixedly connected to the first cooling plate, so that the temperature of the gas driven by the first gas driving component and flowing through the air duct decreases after passing through the first heat dissipation fin.

[0013] In some alternative configurations, the first cooling plate is a blown plate.

[0014] In some alternative configurations, the first cooling plate has a closed flow channel.

[0015] In some alternative forms, the first cooling plate includes a main body and an extension, the main body being disposed adjacent to the charging module to cool the charging module, the extension extending from the main body, and the flow channel including an evaporation end disposed in the main body and a condensation end disposed in the extension.

[0016] In some alternative forms, the in-vehicle wireless charging device further includes a second gas-driven component and a second heat dissipation fin, the second heat dissipation fin being fixedly connected to the extension and disposed adjacent to the second gas-driven component, so as to cool the second heat dissipation fin by gas driven by the second gas-driven component.

[0017] In some alternative forms, the flow channel includes a supply flow channel and a plurality of branch flow channels communicating with the supply flow channel. The supply flow channel delivers liquefied refrigerant from the condensing end to the evaporating end. The plurality of branch flow channels are evenly distributed and extend in a curved manner within the first cooling plate, and at least partially vaporized refrigerant flows back from the evaporating end to the condensing end.

[0018] In some alternative configurations, the in-vehicle wireless charging device further includes a heat-conducting component disposed between the first cooling plate and the charging module.

[0019] The in-vehicle wireless charging device according to the present invention has several beneficial technical effects, especially: the charging module is cooled by a cooling plate disposed below the charging module, and the electronic device is cooled by a gas driving unit disposed below the cooling plate and an air duct communicating with the top of the panel, thereby improving the heat dissipation capacity during high-power charging and ensuring high charging efficiency and charging speed; in addition, the in-vehicle wireless charging device has a relatively simple structure and low cost, so it can be widely used in various types of vehicles.

[0042] The elements in the accompanying drawings are shown for simplicity and clarity and are not necessarily drawn to precise scale or shape. It should be understood that the drawings are not only used for explanation and illustration of the invention, but also, where necessary, to limit the invention. Detailed Implementation

[0043] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using the invention, and are not intended to limit the scope of the invention.

[0044] In this specification, the descriptions of structural positions, such as up, down, top, and bottom, are not absolute but relative. For example, these descriptions are appropriate when the components are arranged as shown in the figure, but they should be changed accordingly when the positions of the components change.

[0045] In this specification, unless otherwise expressly specified and limited, terms such as "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this specification according to the specific circumstances.

[0046] Furthermore, in this specification, the terms "first," "second," etc., are used to describe various elements without intending to limit the positional, temporal, quantitative, or importance relationships of these elements; such terms are only used to distinguish one element from another.

[0047] This invention relates to an improvement on the cooling system of a wireless charging device for charging electronic devices in a vehicle, thereby achieving better cooling performance and ensuring higher charging efficiency and speed. It is understood that the electronic devices to be charged include, but are not limited to, various types of electronic devices such as mobile phones, tablets, and smart wearable devices. Furthermore, the placement of the wireless charging device in the vehicle according to this invention is not limiting; the wireless charging device can, for example, be... Figure 1 The instrument panel CS shown is integrated between the driver's seat and the passenger seat, and can also be integrated into the armrest AR of the front or rear seats.

[0048] Figures 2 to 15 A first embodiment of the wireless charging device according to the present invention is shown.

[0049] like Figures 2 to 5 as well as Figure 8 As shown, the wireless charging device according to the first embodiment includes a panel assembly 1, a compressor assembly 2, a pipeline assembly 3, and a vehicle refrigerator assembly 4.

[0050] like Figures 5 to 7 as well as Figures 11 to 15 As shown, the panel assembly 1 includes a panel 100, a charging module 110, a first cooling plate 120 and a gas driving unit 130 arranged sequentially from top to bottom.

[0051] The top surface of panel 100 forms the exterior surface of the wireless charging device and is used to place at least one electronic device to be charged thereon. In this embodiment, the top surface of panel 100 has two placement slots 101, for example, for placing a mobile phone.

[0052] The charging module 110 is, for example, a PCBA (Printed Circuit Board Assembly) module, which is mounted on the bottom surface of the panel 100 and can wirelessly charge electronic devices placed on the panel 100 through the principle of electromagnetic induction.

[0053] The first cooling plate 120 is connected to the panel 100, for example, via a plurality of connecting portions located at its edge. The first cooling plate 120 is a blown plate, for example, made by a blown process, having an open flow channel Z, so as to cool the charging module 110 by means of a refrigerant flowing in the flow channel Z.

[0054] More specifically, especially as Figures 12 to 14As shown, the flow channel Z includes a supply flow channel Z3 and multiple branch flow channels Z4 disposed downstream of the supply flow channel Z3. The starting end of the supply flow channel Z3 extends slightly outward from the edge of the first cooling plate 120 to form the liquid inlet Z1 of the flow channel Z. The multiple branch flow channels Z4 extend from the ends of the supply flow channel Z3, and are evenly distributed and curved within the first cooling plate 120 to ensure the uniformity of the cooling effect of the first cooling plate 120. The end of each branch flow channel Z4 extends slightly outward from the edge of the first cooling plate 120 to form the liquid outlet Z2 of the flow channel Z.

[0055] In the illustrated embodiment, the flow channel Z includes a supply flow channel Z3 extending from the liquid inlet Z1 to approximately the center of the first cooling plate 120, and two branch flow channels Z4 extending in the opposite direction from the end of the supply flow channel Z3 and symmetrically arranged on both sides of the supply flow channel Z3. The end of each branch flow channel Z4 (i.e., the liquid outlet Z2) is located adjacent to the liquid inlet Z1 to facilitate connection with an external pipeline connector.

[0056] The gas-driven unit 130 includes a housing 131 and a first gas-driven component 132. For example... Figure 7 , Figure 11 and Figure 15 As shown, the housing 131 is fixedly disposed on the bottom surface of the first cooling plate 120 and, together with the end of the panel 100, defines an air duct J communicating with the upper part of the panel 100. The first gas driving component 132 is fixedly disposed in the housing 131 to cool the electronic equipment placed above the panel 100 by means of gas driven by the first gas driving component 132 and flowing through the air duct J. The first gas driving component 132 can be, for example, a fan, a fluid pump, etc.

[0057] The vehicle-mounted wireless charging device according to the first embodiment also preferably includes a first heat dissipation fin 140. For example... Figure 7 , Figure 13 and Figure 15 As shown, the first heat dissipation fin 140 is disposed downstream of the first gas driving device 132 within the air duct J formed by the housing 131 and is fixedly connected to the first cooling plate 120. Since the temperature of the first cooling plate 120 and the first heat dissipation fin 140 is low, the gas driven by the first gas driving device 132 and flowing through the air duct J has its temperature reduced after passing through the first heat dissipation fin 140, thereby better cooling the electronic device.

[0058] According to the first embodiment, the panel assembly 1 and the vehicle refrigerator assembly 4 are cooled by means of a shared compressor assembly 2, thereby improving the integration of the entire device.

[0059] More specifically, such as Figure 5 , Figure 9 and Figure 10As shown, the compressor assembly 2 includes a compressor bracket 210 and a compressor 200, a condenser 220 and a drying chamber 230 connected in sequence. The compressor 200 is fixedly mounted on the compressor bracket 210.

[0060] Similarly, Figure 5 , Figure 9 and Figure 10 As shown, the pipeline assembly 3 includes a control valve 300, a first inlet pipe 330, a pipeline connector 340, a first outlet pipe 350, a second inlet pipe 310, a second outlet pipe 320, and an evaporation pressure regulating valve 360. The "inlet pipe" is usually referred to as a "capillary tube", and the "outlet pipe" is usually referred to as a "reflux pipe".

[0061] The compressor assembly 2 is connected to the inlet end Z1 of the flow channel Z of the first cooling plate 120 through the first inlet pipe 330, and to the outlet end Z2 of the flow channel Z of the first cooling plate 120 through the first outlet pipe 350, so as to form a first cooling circuit together with the first inlet pipe 330, the first cooling plate 120 and the first outlet pipe 350.

[0062] Pipe connector 340 is connected to the end of each of the first inlet pipe 330 and the first outlet pipe 350 opposite to the first cooling plate 120 and is used for convenient insertion into the first cooling plate 120, thereby enabling the first inlet pipe 330 to be connected to the inlet end Z1 of the flow channel Z and the first outlet pipe 350 to be connected to the outlet end Z2 of the flow channel Z. That is, the supply flow channel Z3 of the flow channel Z can be connected to the first inlet pipe 330 through the cooperation of the inlet end Z1 and the pipe connector 340, and each branch flow channel Z4 of the flow channel Z can be connected to the corresponding first outlet pipe 350 through the cooperation of the corresponding outlet end Z2 and the pipe connector 340.

[0063] The compressor assembly 2 is also connected to a second cooling plate 370 (e.g., an inflatable plate) for cooling the compartment 400 of the vehicle refrigerator assembly 4 via a second inlet pipe 310 and a second outlet pipe 320, so as to form a second cooling circuit together with the second inlet pipe 310, the second cooling plate 370 and the second outlet pipe 320.

[0064] The control valve 300 is, for example, a solenoid valve, which is located downstream of the compressor assembly 2 and connected to each of the first inlet pipe 330 and the second inlet pipe 310, so that the first cooling circuit and the second cooling circuit can operate simultaneously or independently without interference by controlling the refrigerant flow rate into the first inlet pipe 330 and the second inlet pipe 310 respectively, and can control the cooling temperature of the first cooling circuit and the second cooling circuit.

[0065] The evaporation pressure regulating valve 360 ​​is provided in the first cooling circuit, for example, between the first liquid outlet pipe 350 and the compressor 200, so as to regulate the pressure in the first cooling circuit when the first cooling circuit is running alone, maintain pressure balance, and thus accurately control the cooling temperature.

[0066] The heat dissipation working principle of the wireless charging device of the first embodiment is briefly described below.

[0067] like Figure 10 As shown, the refrigerant in compressor 200 flows out from position A, passes through condenser 220, and then flows into solenoid valve 300 after passing through drying chamber 230. After being diverted by solenoid valve 300, a portion of the refrigerant flows through first inlet pipe 330 and pipe joint 340, enters flow channel Z of first cooling plate 120, and flows out from flow channel Z after cooling charging module 110. It then flows through first outlet pipe 350 and evaporation pressure regulating valve 360, and finally flows back into compressor 200 from position C, thereby removing heat from first cooling plate 120 and achieving low temperature for first cooling plate 120. The other portion of the refrigerant enters second cooling plate 370 through second inlet pipe 310, and then flows back into compressor 200 from position B through second outlet pipe 320. When the first cooling circuit or the second cooling circuit needs to operate independently, it is only necessary to control the refrigerant to flow only into the first inlet pipe 330 or the second inlet pipe 310 by controlling valve 300.

[0068] like Figure 14 As shown, after the refrigerant flows through the first inlet pipe 330 and through the pipe joint 340, it enters the supply channel Z3 of the first cooling plate 120, then flows to both sides through two branch channels Z4, and then flows back to the first outlet pipe 350 through the pipe joint 340, thereby removing the heat from the first cooling plate 120.

[0069] like Figure 15 As shown, the vehicle-mounted wireless charging device also includes a heat-conducting component disposed between the first cooling plate 120 and the charging module 110. For example, important heat-generating components D, E, F, and G in the charging module 110 are in contact with the first cooling plate 120 through thermally conductive silicone H. The heat of the charging module 110 is carried away by the flow of refrigerant in the flow channel Z of the first cooling plate 120, thereby cooling it down.

[0070] Furthermore, the first heat dissipation fin 140 is directly mounted on the first cooling plate 120. Since the temperature of the first cooling plate 120 can be controlled, for example, between 5°C and 15°C, the temperature of the first heat dissipation fin 140 can also be between 5°C and 15°C. When the first gas driving device 132 is turned on, the gas driven by the first gas driving device 132 decreases in temperature after passing through the first heat dissipation fin 140. Therefore, the cool air can be blown to the electronic equipment for heat dissipation after passing through the air duct J, thereby improving the charging speed.

[0071] Figures 16 to 21 A second embodiment of the wireless charging device according to the present invention is shown.

[0072] like Figures 16 to 21 As shown, the wireless charging device according to the second embodiment includes a panel 100, a charging module 110, a first cooling plate 150 and a gas driving unit 130 arranged sequentially from top to bottom.

[0073] The top surface of panel 100 forms the exterior surface of the wireless charging device and is used to place at least one electronic device to be charged thereon. In this embodiment, the top surface of panel 100 has two placement slots 101, for example, for placing a mobile phone.

[0074] The charging module 110 is, for example, a PCBA module, which is installed on the bottom surface of the panel 100 and can wirelessly charge electronic devices placed on the panel 100 through the principle of electromagnetic induction.

[0075] The first cooling plate 150 is connected to the panel 100, for example, via a plurality of connecting portions located at its edge. The first cooling plate 150 is provided with a closed flow channel Z, which is, for example, a heat spreader, so as to cool the charging module 110 by means of a refrigerant flowing in the flow channel Z.

[0076] Especially Figure 18 and Figure 19 As shown, the first cooling plate 150 includes a generally rectangular main body 151 and an extension 152 extending from the edge of the main body 151. The main body 151 is disposed adjacent to the bottom surface of the charging module 110 to provide cooling for the charging module 110. The flow channel Z includes an evaporation end Z5 disposed in the main body 151 and a condensation end Z6 (i.e., a heat dissipation end) disposed in the extension 152.

[0077] More specifically, the flow channel Z includes a supply flow channel Z3 and multiple branch flow channels Z4 connected to the supply flow channel Z3. The supply flow channel Z3 (also called a "capillary") extends from the condensing end Z6 to the evaporating end Z5, enabling the liquefied refrigerant to be transported from the condensing end Z6 to the evaporating end Z5. The multiple branch flow channels Z4 extend from the ends of the supply flow channel Z3 and are evenly distributed and curved within the first cooling plate 150 to ensure the uniformity of the cooling effect of the first cooling plate 150. Furthermore, these branch flow channels Z4 extend from the evaporating end Z5 to the condensing end Z6, enabling at least partially vaporized refrigerant to flow back from the evaporating end Z5 to the condensing end Z6 and re-enter the supply flow channel Z3. In other words, the supply flow channel Z3 and these branch flow channels Z4 together form a closed cooling circuit.

[0078] In the illustrated embodiment, the flow channel Z includes a supply flow channel Z3 extending from the condensing end Z6 to the evaporating end Z5 at approximately the center position, and two branch flow channels Z4 extending in the opposite direction from the end of the supply flow channel Z3 and symmetrically arranged on both sides of the supply flow channel Z3.

[0079] The gas-driven unit 130 includes a housing 131 and a first gas-driven component 132. For example... Figure 17 and Figure 20 As shown, the housing 131 is fixedly disposed on the bottom surface of the first cooling plate 150 and, together with the end of the panel 100, defines an air duct J communicating with the upper part of the panel 100. The first gas driving component 132 is fixedly disposed in the housing 131 to cool the electronic equipment placed above the panel 100 by means of gas driven by the first gas driving component 132 and flowing through the air duct J. The first gas driving device 132 can be, for example, a fan, a fluid pump, etc.

[0080] The vehicle-mounted wireless charging device according to the second embodiment further preferably includes a second gas-driven component 500 and a second heat dissipation fin 510. In particular, as shown in... Figure 16 , Figure 18 and Figure 21 As shown, the second gas drive component 500 and the second heat dissipation fin 510 are both fixedly connected to the top surface of the extension 152 of the first cooling plate 150 and are arranged adjacent to each other so that the second heat dissipation fin 510 can be cooled by the gas driven by the second gas drive component 500.

[0081] The heat dissipation working principle of the wireless charging device in the second embodiment is briefly described below.

[0082] like Figures 19 to 21As shown, the liquid refrigerant in the condensing end Z6 of the flow channel Z of the first cooling plate 150 reaches the evaporating end Z5 through the supply flow channel Z3. After cooling the charging module 110, the liquid refrigerant at least partially vaporizes and diffuses through the two branch flow channels Z4 until it carries the absorbed heat back to the condensing end Z6 and transfers it to the second heat dissipation fins 510. Thus, the heat of the second heat dissipation fins 510 can be carried away by the gas driven by the second gas driving component 500, so that the refrigerant in the condensing end Z6 is liquefied again and flows back to the evaporating end Z5.

[0083] The vehicle-mounted wireless charging device also includes a heat-conducting component disposed between the first cooling plate 150 and the charging module 110. For example, the heat-generating components in the charging module 110 are in contact with the first cooling plate 150 through thermally conductive silicone H, and the heat of the charging module 110 is carried away and cooled down by the flow of refrigerant in the flow channel Z of the first cooling plate 150. At the same time, the gas (i.e., natural wind) driven by the first gas driving component 132 and flowing through the air duct J will not heat up due to the temperature rise of the charging module 110.
