Description

Technical Field

[0001] This utility model relates to the field of vehicle charging technology, and more specifically, to a vehicle wireless charging device. Background Technology

[0002] In existing wireless charging devices, the charging module is typically fixed to the charging panel via a metal mounting housing. While this design facilitates assembly and maintenance, it also introduces several significant problems. First, the additional mounting housing increases the distance between the charging module and the charging panel, which not only increases the overall size of the device but may also lengthen the heat conduction path, further impacting heat dissipation efficiency. Second, although the metal mounting housing has some thermal conductivity, its overall heat dissipation effect is not ideal, especially during high-load operation, where heat accumulation is significant.

[0003] Furthermore, many devices use natural airflow for cooling to alleviate overheating issues with the charging module. However, the effectiveness of this method is greatly affected by the ambient temperature, and when the casing itself becomes a heat source, the temperature of the airflow blowing onto the phone also increases. This heated airflow can negatively impact the phone's heat dissipation, making it impossible to effectively control the phone's temperature. This not only fails to effectively reduce the phone's operating temperature but also significantly reduces charging efficiency and may even damage battery life due to overheating.

[0049] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] In existing wireless charging devices, the charging module is typically fixed to the charging panel via a metal mounting housing. While this design facilitates assembly and maintenance, it also introduces several significant problems. First, the additional mounting housing increases the distance between the charging module and the charging panel, which not only increases the overall size of the device but may also lengthen the heat conduction path, further impacting heat dissipation efficiency. Second, although the metal mounting housing has some thermal conductivity, its overall heat dissipation effect is not ideal, especially during high-load operation, where heat accumulation is significant.

[0055] Furthermore, many devices use natural airflow for cooling to alleviate overheating issues with the charging module. However, the effectiveness of this method is greatly affected by the ambient temperature, and when the casing itself becomes a heat source, the temperature of the airflow blowing onto the phone also increases. This heated airflow can negatively impact the phone's heat dissipation, making it impossible to effectively control the phone's temperature. This not only fails to effectively reduce the phone's operating temperature but also significantly reduces charging efficiency and may even damage battery life due to overheating.

[0056] Therefore, existing heat dissipation solutions in wireless charging devices have many shortcomings and urgently need improvement. For solutions to these problems, please refer to... Figures 1 to 3 ,in, Figure 1 This is a 10-axis projection diagram of an in-vehicle wireless charging device. Figure 2 A schematic diagram of the front view of the vehicle-mounted wireless charging device 10. Figure 3 This is a schematic diagram of the rear structure of the in-vehicle wireless charging device 10. This embodiment of the invention provides an in-vehicle wireless charging device 10 that effectively reduces the distance between the charging module 300 and the charging panel 100, and significantly improves heat dissipation performance, ensuring high-efficiency and stable charging even under high load conditions. This need has driven research and development on more advanced heat dissipation technologies and structural designs, aiming to provide more optimized solutions to meet market demand for high-performance wireless charging devices.

[0057] For more details, please continue reading. Figures 4 to 21 The vehicle-mounted wireless charging device 10 includes a charging panel 100, a mounting base 200, a charging module 300, and a heat dissipation module 400.

[0058] The charging panel 100 is used to place the electronic device S for wireless charging via the charging module 300. The electronic device S can be, but is not limited to, mobile phones, tablets, or other electronic products. The charging panel 100 is provided with an air outlet 110, which faces the electronic device S.

[0059] like Figure 15 and Figure 17As shown, the mounting base 200 is connected to the charging panel 100, and a mounting cavity 210 is formed between the mounting base 200 and the charging panel 100. The mounting base 200 is provided with a first heat dissipation channel 220 and a second heat dissipation channel 230. The first heat dissipation channel 220 is connected to the mounting cavity 210, and the second heat dissipation channel 230 is connected to the air outlet 110. The heat dissipation module 400 is disposed on the mounting base 200.

[0060] Therefore, the mounting base 200 is directly mounted on the charging panel 100, and the charging module 300 is placed inside the mounting cavity 210 and mounted on the charging panel 100, thereby reducing the gap between the charging module 300 and the electronic device S, thus improving charging efficiency. Furthermore, compared with existing charging devices, this increases the integration level of the in-vehicle wireless charging device 10 and reduces production costs. Moreover, by eliminating the traditional metal back cover, this charging device becomes more compact and easier to install and maintain. This integrated design not only simplifies the assembly process but also reduces unnecessary parts, further lowering manufacturing costs.

[0061] Furthermore, based on the aforementioned structural improvements, the mounting base 200 is equipped with a first heat dissipation channel 220 and a second heat dissipation channel 230. Cool air is introduced into the first heat dissipation channel 220 through the heat dissipation module 400 to cool the charging module 300, quickly removing heat generated by the heating elements within the charging module 300 and preventing overheating. Cool air is also introduced into the second heat dissipation channel 230 through the heat dissipation module 400, and the second heat dissipation channel 230 guides the cool air to flow across the surface of the charging panel 100, removing heat generated by the mobile phone or other electronic devices S during charging, ensuring the device remains at a suitable operating temperature. Therefore, while simultaneously providing air cooling for the electronic device S, the charging module 300 is also cooled. This enhances the heat dissipation capacity of the in-vehicle wireless charging device 10 without compromising or even improving the charging function, thereby increasing high-power charging efficiency.

[0062] In summary, this utility model embodiment provides an in-vehicle wireless charging device 10. By eliminating the traditional metal back cover and adopting an integrated design, the charging module 300 is tightly integrated with the charging panel 100, and dual heat dissipation channels are provided to achieve efficient heat dissipation and precise temperature control. This design not only significantly improves the charging efficiency of the wireless charging device, but also greatly enhances the charging efficiency at high power without compromising or even improving functionality. At the same time, the highly integrated design reduces production costs and simplifies the maintenance process, providing users with an efficient, reliable, and economical in-vehicle wireless charging solution.

[0063] Furthermore, to further improve the heat dissipation capability of the charging module 300, please refer to [link / reference needed]. Figures 6 to 9The vehicle-mounted wireless charging device 10 also includes heat dissipation fins 500, which are disposed at the bottom of the charging module 300.

[0064] It is understandable that by attaching the heat dissipation fins 500 to the bottom of the charging module 300, the heat dissipation area of ​​the heat dissipation module 400 can be effectively increased, so that its heat can be quickly dissipated into the mounting cavity 210 through the heat dissipation fins 500, and heat exchange can be carried out through the cold air delivered by the first heat dissipation channel 220, thereby achieving effective heat dissipation of the heat dissipation module 400.

[0065] The heat dissipation fins 500 are typically made of high thermal conductivity materials (such as aluminum or copper). These materials have excellent thermal conductivity and can quickly conduct the heat from the charging module 300 to the fin surface, further accelerating the heat dissipation.

[0066] It is worth mentioning that, such as 4 and Figure 5 As shown, Figure 4 Exploded view of charging panel 100 and charging module 300. Figure 5 The diagram shows the assembly of the vehicle-mounted wireless charging device 10. The charging module 300 includes, from top to bottom, an NFC (Near Field Communication) film, a coil 320, a magnetic shielding plate 330, a coil bracket 340, and a PCBA (Printed Circuit Board Assembly) board. The NFC film 310 is mounted on the charging panel 100, and the heat dissipation fins 500 are mounted on the PCBA board 350. That is, the heat dissipation fins 500 mainly dissipate heat from the PCBA board 350.

[0067] Furthermore, to ensure that the hot air generated after the cold air input through the first heat dissipation channel 220 exchanges heat with the PCBA board 350 and heat dissipation fins 500 of the charging module 300 can be discharged from the mounting cavity 210 in a timely manner, such as Figure 17 and Figure 18 As shown, the mounting base 200 is provided with an exhaust port 240 that communicates with the mounting cavity 210.

[0068] Furthermore, by setting the exhaust vent 240 opposite to the outlet of the first heat dissipation channel 220, the air circulation efficiency is increased, allowing cold air to enter the mounting cavity 210 more quickly and smoothly, and to flow out of the exhaust vent 240 quickly after heat exchange. This not only improves the cooling efficiency, but also effectively prevents the already heated air from being drawn back into the mounting cavity 210, thus avoiding the problem of secondary heating caused by heat backflow.

[0069] Therefore, the heat dissipation fins 500 extend along the outlet of the first heat dissipation channel 220 toward the exhaust port 240, so that the heat dissipation fins 500 are located on the air flow path, thereby further improving the heat exchange efficiency between the cold air and the heat dissipation fins 500, thereby improving the heat dissipation efficiency of the charging module 300 board.

[0070] It is understood that the number of heat dissipation fins 500 can be one, but in order to further improve the heat dissipation efficiency, the number of heat dissipation fins 500 can also be multiple. Multiple heat dissipation fins 500 are spaced apart at the bottom of the charging module 300 to further increase the contact area between the heat dissipation fins 500 and the cold air, thereby further improving the heat exchange efficiency between the cold air and the heat dissipation fins 500, thereby improving the heat dissipation efficiency of the charging module 300 board.

[0071] It should also be noted that the exhaust vent 240 can be a single through hole structure or it can be composed of multiple horizontally spaced through holes, so as to ensure both the air outlet area and the structural strength of the mounting base 200.

[0072] Furthermore, such as Figure 10 , Figure 11 as well as Figure 21 As shown, the first heat dissipation channel 220 includes a main channel 221 and at least one secondary channel 222, that is, the number of secondary channels 222 can be one or more.

[0073] Specifically, one end of the main channel 221 is connected to the heat dissipation module 400, and the other end is connected to at least one secondary channel 222, which is connected to the mounting cavity 210.

[0074] It is worth mentioning that the number of exhaust vents 240 can be one, that is, at least one secondary channel 222 is set with a corresponding large area exhaust vent 240.

[0075] Of course, there can be multiple exhaust vents 240. In this case, multiple exhaust vents 240 are set one-to-one with the outlets of multiple secondary channels 222, and multiple heat dissipation fins 500 are set in multiple groups. Multiple secondary channels 222 are set one-to-one with multiple groups of heat dissipation fins 500.

[0076] In this embodiment, cold air is supplied to multiple secondary channels 222 through the main channel 221, so that cold air is simultaneously input into the mounting cavity 210 through multiple secondary channels 222. This provides a flow area for cold air, allowing more cold air to enter the heat dissipation cavity, thereby improving heat dissipation efficiency. In addition, the input of cold air into the mounting cavity 210 through multiple secondary channels 222 can also make the cold air blown relatively evenly to multiple areas of the mounting cavity 210, ensuring that heat can be effectively removed and avoiding local overheating.

[0077] In addition, each outlet of the secondary channel 222 corresponds to a set of heat dissipation fins 500 and an exhaust port 240, ensuring that cold air is precisely blown from the secondary channel 222 to the corresponding set of heat dissipation fins 500. This allows the heat of the charging module 300 to be carried away more effectively and avoids the problem of uneven airflow or insufficient cooling in some areas, thereby further improving heat dissipation efficiency.

[0078] Furthermore, the mounting base 200 is also equipped with a first partition 250 and a second partition 260.

[0079] The second separator 260 is used to separate the first heat dissipation channel 220 and the second heat dissipation channel 230.

[0080] At least one first partition 250 is provided in the second heat dissipation channel 230. The first partition 250 is used to divide the second heat dissipation channel 230 into multiple second heat dissipation sub-channels 231. The charging panel 100 is provided with at least one air outlet 110. That is, the number of air outlets 110 can be one or multiple. When the number of air outlets 110 is multiple, the multiple second heat dissipation sub-channels 231 are respectively connected to the multiple air outlets 110 one by one.

[0081] It is understood that the first partition 250 and the second partition 260 can be made with the mounting base 200 using an integral molding process, or the first partition 250 and the second partition 260 can be separate components that are detachably installed on the mounting base 200.

[0082] Furthermore, 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 at the same time.

[0083] It should be noted that multiple air outlets 110 can be set in one charging area 120, or at least one air outlet 110 can be set in multiple charging areas 120.

[0084] It is worth mentioning that the number of heat dissipation fins 500 is the same as the number of charging areas 120. That is, the heat dissipation fins 500 are set below the charging module 300 and the corresponding heat dissipation area. In this way, multiple sets of heat dissipation fins 500 can dissipate heat from multiple parts of the charging module 300 and the charging area 120, ensuring that the main heat-generating parts of the heat dissipation module 400 can be effectively cooled.

[0085] Furthermore, the number of secondary channels 222 is the same as that of charging area 120.

[0086] Specifically, such as Figure 14 and Figure 15 As shown, when there are multiple charging areas 120, each charging area 120 is provided with an air outlet 110, and the second heat dissipation channel 230 is provided with at least one first separator 250. The first separator 250 is used to divide the second heat dissipation channel 230 into multiple second heat dissipation sub-channels 231, and the multiple second heat dissipation sub-channels 231 are respectively connected to the multiple air outlets 110 one by one.

[0087] Therefore, the second heat dissipation channel 230 is divided into multiple second heat dissipation sub-channels 231 by the first separator 250, so that multiple air outlets 110 blow heat to multiple electronic devices S placed in the charging area 120 respectively.

[0088] As shown in the figure, the charging panel 100 of this embodiment provides two charging areas 120. Correspondingly, there are two secondary channels 222 and one first separator 250. Therefore, there are two second heat dissipation secondary channels 231, and each of the two charging areas 120 is provided with an air outlet 110. Of course, in other embodiments of this utility model, the charging area 120, secondary channel 222, first separator 250, second heat dissipation secondary channel 231 and air outlet 110 can be set to other numbers, which are not specifically limited here.

[0089] Furthermore, the charging area 120 is provided with a ventilation groove 130, and the air outlet 110 is provided in the ventilation groove 130.

[0090] In this embodiment, 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.

[0091] Furthermore, such as Figures 15 to 17 As shown, the heat dissipation module 400 includes an airflow element 410 and a heat exchange element 420. Both the airflow element 410 and the heat exchange element 420 are disposed on the mounting base 200. The heat exchange element 420 includes a cooling chamber 421 and a heat dissipation chamber 422. The airflow element 410 is used to input gas into the cooling chamber 421. The first heat dissipation channel 220 and the second heat dissipation channel 230 are both connected to the cooling chamber 421. The heat dissipation chamber 422 is used to exhaust hot air.

[0092] In this embodiment, the airflow element 410 can be, but is not limited to, a fan. By mounting the airflow element 410 on the bottom of the mounting base 200, air is drawn in from the outside through the airflow element 410 and delivered to the heat exchange element 420.

[0093] It is worth mentioning that the heat exchange element 420 also includes a Peltier 423, which is disposed between the cooling chamber 421 and the heat dissipation chamber 422. The heat absorption end of the Peltier 423 corresponds to the cooling chamber 421. Thus, when the airflow element 410 delivers air to the cooling chamber 421, the Peltier 423 absorbs heat to convert the air into cold air, thereby allowing the cold air to flow to the first heat dissipation channel 220 and the second heat dissipation channel 230 respectively.

[0094] The heat from the Peltier 423 is released in the heat release chamber 422 through the heat release end. It can be understood that part of the air delivered by the airflow element 410 enters the cooling chamber 421 to form cold air, while the other part enters the heat release chamber 422 and carries the heat in the heat release end out to the outside of the mounting base 200.

[0095] As can be seen, the heat exchange module 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 module uses Peltier 423 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.

[0096] Furthermore, the vehicle-mounted wireless charging device 10 also includes a sealing element 600, which is disposed between the charging panel 100 and the mounting base 200. The charging panel 100, the sealing element 600, and the mounting base 200 together form a mounting cavity 210.

[0097] In this embodiment, the seal 600 can be made of foam material and is ring-shaped. Therefore, placing the seal 600 between the charging panel 100 and the mounting base 200 not only provides a reliable sealing effect for the formed mounting cavity 210 and prevents external substances such as liquids, gases, or dust from entering the housing, but also, due to its good elasticity and shock absorption capacity, can buffer the charging panel 100 and the mounting base 200 when they are subjected to vibration or impact, reducing the impact on internal components and extending the service life of the device. Secondly, due to its soft and elastic properties, the seal 600 can also help reduce noise caused by vibration and improve the user experience.

[0098] In summary, the in-vehicle wireless charging device 10 provided by this utility model generates directional airflow through the airflow element 410, which is cooled by the heat exchange element 420. The first heat dissipation channel 220 guides the cold air into the mounting cavity 210, allowing the cold air to directly act on the PCBA board 350 and its heat dissipation fins 500, significantly improving heat dissipation efficiency. Simultaneously, the second heat dissipation channel 230 guides the cold air towards the bottom of the electronic device S. This not only effectively reduces the operating temperature of the PCBA module but also improves the overall cooling effect of the electronic device S. Furthermore, the Peltier 423 in the heat exchange element 420 enables precise temperature control in localized areas, further enhancing the system's heat dissipation capacity. Thus, without compromising or even enhancing functionality, the charging efficiency of the wireless charging device at high power is significantly improved.

[0099] Meanwhile, to further optimize the device structure and reduce costs, the traditional wireless charging metal back cover was eliminated, and the charging module 300 was integrated with the charging panel 100. The integrated charging panel 100 is directly assembled with the mounting base 200, and the charging module 300 is directly mounted onto the charging panel 100, greatly improving the integration of the wireless charging device and reducing manufacturing costs. Because the charging module 300 is tightly integrated with the charging panel 100, the gap between the charging module 300 and the electronic device S is significantly reduced, which not only reduces electromagnetic interference but also improves charging efficiency. Furthermore, the integrated design makes the device more compact, facilitating installation and maintenance, and also provides users with a simpler and more aesthetically pleasing product appearance.

[0100] In summary, the in-vehicle wireless charging device 10 achieves efficient heat dissipation and precise temperature control by eliminating the traditional metal back cover, combining airflow element 410 and Peltier 423 technology, and attaching heat dissipation fins 500 to the PCBA board 350, designing a dual heat dissipation channel. This significantly improves the charging efficiency of the wireless charging device. Simultaneously, by integrating the wireless charging panel 100 with the charging module 300, the device's integration level is improved, manufacturing costs are reduced, and the gap between the charging module 300 and the electronic device S is decreased, further enhancing charging efficiency. This series of innovations not only solves the problems of poor heat dissipation and high cost in existing technologies but also provides users with a more efficient, reliable, and economical wireless charging solution, meeting the market demand for high-performance wireless charging devices.

Various modifications and variations can be made to this utility model by those skilled in the art.
