Detailed Implementation
[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0052] In the current wireless charging field, most wireless charging devices rely on direct fan cooling. While this method is simple and direct, it has many shortcomings in practical applications, especially in high-power scenarios where its cooling effect is insufficient.
[0053] Specifically, traditional fans can only remove heat by accelerating airflow, but cannot actively lower the ambient temperature. Especially in high-temperature environments, the air blown out by the fan is already hot, making it difficult to effectively reduce the operating temperature of charging devices. This leads to severe overheating of the charging electronic devices, affecting not only the user experience but also significantly reducing charging efficiency.
[0054] In summary, most existing wireless charging devices use direct fan cooling, but this method has limited cooling effect in high-power applications and cannot meet the needs of modern devices for efficient heat dissipation.
[0055] To address the technical problems existing in the prior art, this utility model provides a vehicle-mounted wireless charging device 10, applicable to vehicles such as automobiles and new energy vehicles. Figure 1 As shown, the in-vehicle wireless charging device 10 is installed at the vehicle body location indicated by A in Figure 1. The in-vehicle wireless charging device 10 proposed in this application incorporates a cooling module and air duct system. By combining active cooling with optimized airflow paths, the heat dissipation performance of the wireless charging device is significantly improved. This improvement not only enhances the charging efficiency and stability of the charging device but also extends its service life, providing users with a more reliable and efficient wireless charging experience.
[0056] For more details, please continue reading. Figures 2 to 18 The vehicle-mounted wireless charging device 10 includes a charging panel 100, a first channel 200, a heat exchange element 300, and an airflow element 400.
[0057] The charging panel 100 is used to place the electronic device S so that the charging module 700 can wirelessly charge the electronic device S. It can be understood that the electronic device S can be, but is not limited to, electronic products such as mobile phones and tablets.
[0058] The charging panel 100 is provided with an air outlet 110, and the first channel 200 is connected to the air outlet 110; the heat exchange element 300 is connected to the first channel 200; the airflow element 400 is connected to the heat exchange element 300 and is used to deliver air to the heat exchange element 300 so as to deliver cold air to the bottom of the electronic device S through the first channel 200.
[0059] Therefore, when the electronic device S is placed on the charging panel 100 for wireless charging, air is supplied to the heat exchange element 300 through the airflow element 400. The air is cooled by the efficient heat exchange process of the heat exchange element 300, and then delivered to the air outlet 110 through the first channel 200. Finally, the cooled air is blown from the air outlet 110 towards the bottom of the electronic device S, thus achieving effective heat dissipation and cooling. This not only improves the stability and lifespan of the electronic device S but also provides users with a quieter and more efficient user experience.
[0060] It is worth mentioning that the surface of the charging panel 100 is made of at least one of TPEE (Thermoplastic Polyester Elastomer), TPU (Thermoplastic Polyurethanes), TPC (Thermoplastic Copolyester Elastomer), or other materials. The charging panel 100 made of this material has excellent mechanical properties, wear resistance, and protective properties. It can not only provide users with a comfortable tactile experience during operation, but also achieve diverse appearance designs through different colors and surface treatments to meet different market demands.
[0061] Furthermore, the vehicle-mounted wireless charging device 10 also includes a connecting pipe 500, and the heat exchange element 300 includes a cooling chamber 310 and a heat dissipation chamber 320. One end of the connecting pipe 500 is connected to the outlet of the airflow element 400, and the other end is connected to both the cooling chamber 310 and the heat dissipation chamber 320. The heat dissipation chamber 320 is used to discharge hot air, and the cooling chamber 310 is connected to the first channel 200 and is used to deliver cold air to the first channel 200.
[0062] In this embodiment, the airflow element 400 may be, but is not limited to, a fan, impeller, or other related device capable of blowing air.
[0063] Since the airflow element 400 and the heat exchange element 300 are assembled in different positions, there may be angular or connection position deviations when they are assembled. Therefore, the airflow element 400 and the heat exchange element 300 can be securely connected by the connecting pipe 500 to ensure that the outlet of the airflow element 400 is connected to the heat exchange element 300.
[0064] It is worth mentioning that the heat exchange element 300 also includes a Peltier, which is disposed between the cooling chamber 310 and the heat dissipation chamber 320, with the heat absorption end of the Peltier corresponding to the cooling chamber 310. Thus, when the airflow element 400 delivers air to the cooling chamber 310, the Peltier absorbs heat to convert the air into cold air, thereby allowing the cold air to flow to the first channel 200.
[0065] The heat generated by the Peltier is released in the heat exchange chamber 320 through the heat release end. It can be understood that part of the air transported by the airflow element 400 enters the cooling chamber 310 to form cold air, while the other part enters the heat exchange chamber 320 and discharges the heat in the heat release end to the outside of the heat exchange element 300.
[0066] As can be seen, the heat exchange element 300 is small in size and compact in structure, making it suitable for integration into designs with limited space. Compared with traditional refrigerant systems, the heat exchange element 300 uses Peltier without using any chemical refrigerant, reducing the risk of environmental pollution, and can quickly respond to changes in current to achieve rapid heating and cooling.
[0067] Furthermore, the heat exchange element 300 also has a discharge channel 330 connected to the heat dissipation chamber 320, so as to discharge the heat of the heat dissipation chamber 320 through the discharge channel 330.
[0068] It is understandable that the emission channel 330 can be set horizontally or vertically depending on the usage or design requirements.
[0069] Although the heat exchange element 300 can effectively and quickly convert air into cold air in the cooling chamber 310, it also makes it easy for condensation to occur at the rear end of the cooling chamber 310. As a result, water accumulates inside the heat exchange element 300, which may cause other components to short circuit or even be damaged, thereby shortening the service life of the vehicle wireless charging device 10.
[0070] Therefore, in order to avoid the harm caused by condensation, such as Figures 8 to 11 , Figures 15 to 18 As shown, the vehicle-mounted wireless charging device 10 also includes a condensation pipe 600, which is disposed between the first channel 200 and the cooling chamber 310. The condensation pipe 600 is provided with a condensation port 610, which is used to drain condensate.
[0071] In practical applications, if a user accidentally spills water onto the charging panel 100, the water can flow from the air outlet 110 on the charging panel 100 through the first channel 200 into the condenser pipe 600 and be discharged from the condenser outlet 610, thereby preventing water from entering the device and causing other electronic components to short circuit or even be damaged.
[0072] In this embodiment, the condenser pipe 600 can be a separate pipe or it can be integrally formed with the cooling chamber 310 of the heat exchange element 300. It can be adjusted according to actual usage requirements, and no specific limitation is made here.
[0073] In order for the condensate to flow smoothly from the condensate pipe 600 to the condensate outlet 610 and then be discharged from the condensate pipe 600 through the condensate outlet 610, the condensate outlet 610 is located at the lowest point of the bottom wall of the condensate pipe 600. This allows the condensate to flow automatically towards the condensate outlet 610 under the action of gravity within the condensate pipe 600, thereby improving the discharge efficiency of the condensate and preventing water accumulation within the condensate pipe 600.
[0074] Specifically, as shown in the figure, the bottom wall of the condensate pipe 600 is parallel to the horizontal line (e.g., Figure 11 (as shown by the dashed line in the middle H) forms an angle (as shown by...) Figure 11 (As shown in the middle angle a) is set, the included angle is greater than or equal to 5° and less than 90°.
[0075] In this embodiment, by setting the bottom wall of the condensation pipe 600 to have an acute angle greater than 5° with the horizontal, the condensate can flow naturally along the inclined bottom wall under the action of gravity, which can drain the condensate more quickly, thoroughly and efficiently, and reduce water accumulation. This avoids corrosion and bacterial growth inside the pipe, and extends the maintenance cycle and service life of the vehicle wireless charging device 10.
[0076] Optionally, the angle between the bottom wall of the condensate pipe 600 and the horizontal line can be 5°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, etc. Of course, the angle can also be other values, which will not be elaborated here, as long as it is between 5° and 90°.
[0077] Furthermore, in order to increase the number of electronic devices S that the in-vehicle wireless charging device 10 can charge simultaneously, the charging panel 100 is provided with at least one charging area 120. That is, the charging panel 100 can be provided with one charging area 120 to wirelessly charge one electronic device S. Of course, multiple charging areas 120 can also be provided on the charging panel 100 to wirelessly charge multiple electronic devices S simultaneously.
[0078] Each of the multiple charging areas 120 is provided with an air outlet 110. The first channel 200 includes a main pipe 210 and at least one secondary pipe 220. That is, the number of secondary pipes 220 can also be one or more. One end of the main pipe 210 is connected to the heat exchange element 300, and the other end is connected to at least one secondary pipe 220. At least one secondary pipe 220 is connected to at least one air outlet 110.
[0079] In this embodiment, by setting multiple charging areas 120 on the charging panel 100, when multiple electronic devices S are placed in the charging areas 120 for charging, the cold air delivered by the heat exchange element 300 flows through the main pipe 210 to multiple secondary channels and blows through multiple air outlets 110 to the bottom of the charging device, so as to achieve simultaneous cooling of multiple electronic devices S.
[0080] It should be noted that each charging area 120 can be equipped with one air outlet 110 or multiple air outlets 110.
[0081] It is understood that in practical applications, most users who need charging in the vehicle are passengers in the driver's seat and the front passenger seat. Therefore, as shown in the figure, the charging panel 100 provided in this embodiment has two charging areas 120. This can meet the usage needs of most usage scenarios while avoiding increased production costs due to an excessive number of charging areas 120. Of course, in other embodiments of this utility model, the charging panel 100 can be set to other numbers, which are not specifically limited here.
[0082] In detail, the charging area 120 is set at an angle, and the air outlet 110 is located at the lowest position of the charging area 120.
[0083] It should be noted that the surface of the charging panel 100 has a recessed structure, and the charging area 120 is located within the recessed structure. In other words, when the electronic device S is placed in the charging area 120, the sidewall forming the recessed structure can limit the electronic device S to a certain extent, preventing the electronic device S from sliding out of the charging area 120.
[0084] In this embodiment, by placing the air outlet 110 at the lowest position of the charging area 120, the air outlet 110 is not easily noticeable visually, thus making it a hidden air outlet 110 and improving the aesthetics of the charging panel 100.
[0085] Furthermore, by positioning the air outlet 110 at the lowest point of the charging area 120, water on the charging panel 100 can flow towards the air outlet 110 under gravity and seep into the first channel 200 when present on the charging panel 100. Therefore, by providing a condensation pipe 600 connected to the first channel 200 and a condensation outlet 610 within it, water can be promptly drained through the condensation outlet 610, preventing disruption to the normal operation of the charging module and other electronic components.
[0086] Furthermore, the charging area 120 is provided with a ventilation groove 130, and the air outlet 110 is located at the lowest position of the ventilation groove 130.
[0087] Therefore, when the electronic device S is placed in the charging area 120, a gap can be formed between the bottom of the electronic device S and the ventilation groove 130. By setting the air outlet 110 at the connection between the bottom wall and the side wall of the ventilation groove 130, cold air can be blown from the air outlet 110 to the bottom of the electronic device S, thereby effectively dissipating heat from the electronic device S. Furthermore, the gap between the electronic device S and the ventilation groove 130 can accommodate more cold air, thus further improving the heat exchange efficiency of the cold air to the electronic device S.
[0088] Furthermore, by placing the air vent 110 at the lowest position of the ventilation recess 130, the air vent 110 can be further concealed, improving the aesthetics of the charging panel 100; and it can also reduce the intrusion of external dust and moisture to a certain extent, thus enhancing the dustproof and waterproof performance of the vehicle wireless charging device 10, making it particularly suitable for the complex climatic conditions in the vehicle environment.
[0089] Furthermore, the in-vehicle wireless charging device 10 also includes a charging module 700. For example... Figure 2 , Figure 3 , Figures 7 to 10 As shown, the airflow element 400 is connected to the charging module 700, and the inlet of the airflow element 400 is connected to the interior of the charging module 700.
[0090] In this embodiment, the charging module 700 is disposed at the bottom of the charging panel 100, the heat exchange element 300 and the airflow element 400 are both disposed at the bottom of the charging module 700, and the first channel 200 is disposed on one side of the charging module 700, the airflow element 400 and the heat exchange element 300. Specifically, one end of the first channel 200 is connected to the heat exchange element 300, and the first channel 200 extends in a vertical direction away from the heat exchange element 300 to the height of the air outlet 110, and the other end of the first channel 200 is bent and connected to the air outlet 110.
[0091] Therefore, by setting the first channel 200, the airflow path is optimized and unnecessary bends are reduced, so that cold air can flow to the target area through the first channel 200 with the shortest path and the least resistance, thereby reducing system resistance. It also allows the airflow element 400 to operate at a lower speed, thereby reducing noise and energy consumption.
[0092] Specifically, the charging module 700 includes a charging element 710 and a base 720. The base 720 is connected to the bottom of the charging panel 100 to form a mounting cavity 730. The charging element 710 is disposed in the mounting cavity 730. The base 720 is provided with an opening 721, which is connected to the inlet of the airflow element 400.
[0093] In this embodiment, the number of openings 721 can be one or more. When there are multiple openings 721, there are also multiple airflow elements 400. The inlets of the multiple airflow elements 400 are respectively arranged in a one-to-one correspondence with the multiple openings 721, so that hot air from the mounting cavity 730 can be drawn out simultaneously through the multiple airflow elements 400, thereby further improving the heat dissipation effect on the charging element 710. Of course, the number of airflow components can also be one, that is, the airflow component is connected to multiple openings 721 through one inlet, thereby increasing the ventilation area and also improving the heat dissipation effect on the charging element 710.
[0094] It is understandable that the base 720 of the charging module 700 is provided with an air inlet to ensure that the airflow element 400 can smoothly draw out the hot air in the mounting cavity 730. Thus, while air is delivered to the heat exchange element 300 through the airflow element 400, the hot air in the mounting cavity 730 can also be discharged, thereby playing a certain role in heat dissipation and cooling of the charging element 710.
[0095] In addition, part of the air delivered by the airflow element 400 enters the cooling chamber 310 to form cold air, while the other part enters the heat dissipation chamber 320 and dissipates the heat in the heat dissipation end.
[0096] It is worth mentioning that the charging element 710 is mounted on the charging panel 100, which can reduce the gap between the charging element 710 and the electronic device S, thereby improving the charging efficiency; and compared with the existing charging device, it improves the integration level of the vehicle wireless charging device 10 and thus reduces the production cost.
[0097] Specifically, the charging element 710 includes, from top to bottom, an NFC film (Near Field Communication), a coil, a magnetic shielding plate, a coil support, and a PCBA board (Printed Circuit Board Assembly), wherein the NFC film is mounted on the charging panel 100.
[0098] Of course, in other embodiments of this utility model, such as Figures 12 to 18 As shown, the vehicle-mounted wireless charging device 10 also includes a second channel 800, and the charging panel 100 is also provided with a return air vent 140. One end of the second channel 800 is connected to the return air vent 140, and the other end is connected to the inlet of the airflow element 400.
[0099] In this embodiment, when the air outlet 110 blows cold air onto the electronic device S placed on the charging area 120, some of the cold air can enter the return air outlet 140 through the gap between the electronic device S and the charging area 120. Finally, the air from the return air outlet 140 flows through the second channel 800 to the inlet of the airflow element 400. The air that re-enters the airflow element 400 then flows through the heat exchange element 300, the first channel 200, and the air outlet 110 in sequence, thus forming a circulating airflow. Compared with unidirectional or intermittent flow, this method can more effectively maintain the internal temperature stability of the device. Furthermore, the circulating airflow can flow through more areas of the charging device, thus ensuring that multiple heat-generating elements can be adequately cooled to a certain extent, avoiding local overheating.
[0100] Furthermore, the circulating airflow can reduce airflow resistance to a certain extent, allowing the airflow element 400 to achieve the expected heat dissipation effect without needing to operate at a high speed, thus reducing noise and energy consumption. In addition, in high-power applications, the charging device will generate more heat, and the circulating airflow can quickly remove this extra heat, ensuring that the charging device can still operate stably under high load conditions.
[0101] It should be noted that in some other embodiments of this utility model, part of the inlet of the airflow element 400 is connected to the mounting cavity 730, and another part of the inlet of the airflow element 400 is also connected to the second channel 800.
[0102] In detail, the first channel 200 and the second channel 800 are located at both ends of the charging panel 100, so the air outlet 110 and the air return vent 140 are also located on both sides of the charging area 120. That is to say, after the cold air blows from the air outlet 110 to the electronic device S placed on the charging area 120, the air after heat exchange flows directly toward the air return vent 140 and is more likely to flow back to the airflow element 400 from the second channel 800. Therefore, it is easier to form a circulating airflow on the charging device, thereby further improving the heat dissipation efficiency.
[0103] It is also worth mentioning that the charging panel 100 has connecting sections for the air outlet 110 and the air return 140. That is, the air outlet 110 is connected to the first channel 200 through the connecting section, and the air return 140 is connected to the second channel 800 through the channel connecting section.
[0104] Furthermore, such as Figure 19 As shown, the charging panel 100 is provided with a light-emitting part 150, which is used to display the charging status of the electronic device S.
[0105] Specifically, the charging status of the electronic device S can be indicated by the color of the light displayed by the light-emitting part 150. For example, the light-emitting part 150 emits green light to indicate that the electronic device S is charging, while the light-emitting part 150 emits blue light to indicate that the electronic device S is fully charged.
[0106] Furthermore, the light-emitting part 150 can also serve as a warning or alarm. For example, if the light-emitting part 150 emits red light, it indicates that the charging device S is in an abnormal state. Optionally, if there is a metal foreign object between the electronic device S and the charging panel 100, the light-emitting part 150 can emit red light.
[0107] Alternatively, the charging speed of the electronic device S can be displayed by the flow speed of the light-emitting part 150, or the charging progress of the electronic device S can be displayed by the length, width or area of the light-emitting part 150.
[0108] It is understood that the light-emitting unit 150 can be adjusted according to actual needs, and the light color and corresponding state displayed by the light-emitting unit 150 are not limited to the above description, and are not specifically limited here.
[0109] In summary, this utility model provides an in-vehicle wireless charging device 10. Air is supplied to the heat exchange element 300 via the airflow element 400. The air is cooled by the efficient heat exchange process of the heat exchange element 300, and then guided to the air outlet 110 via the first channel 200, ultimately blowing directly onto the bottom of the electronic device S from the air outlet 110. This design not only significantly improves heat dissipation but also brings several benefits. First, this method effectively dissipates and cools the electronic device S. The cold air directly acts on the key heat-generating areas at the bottom of the electronic device S, quickly removing heat and preventing localized overheating, thus improving the user experience. This cooling method is particularly important during high-power charging, ensuring that the device maintains optimal performance during prolonged operation. Second, the design of the first channel 200 reduces flow resistance in the airflow path, allowing the airflow element 400 to operate at lower speeds, thereby reducing noise levels. Furthermore, since cool air can more effectively cover the heat-generating area, the airflow element 400 does not need to operate at higher power to achieve the expected heat dissipation effect, further reducing energy consumption and providing a quieter and more efficient user experience.
[0110] Finally, this cooling system is not only suitable for in-vehicle wireless charging devices 10, but can also be widely used in other electronic devices S that require efficient heat dissipation. Through reasonable airflow management and efficient heat exchange design, it provides users with an aesthetically pleasing and practical solution, significantly improving the overall competitiveness of the product and user satisfaction. This series of improvements not only solves the heat dissipation problem in existing technologies, but also lays a solid foundation for the development of future high-performance electronic devices S.
[0111] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
