However, since the wireless charging module includes a filter plate and a transmitting coil arranged in sequence in a direction away from the carrying portion, the transmitting coil and the receiving coil of the device to be charged are separated by at least the filter plate and the carrying portion, resulting in a large distance between the transmitting coil and the receiving coil. This leads to low wireless charging efficiency and maximum charging power, as well as poor charging stability. Utility Model Content

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0042] This application provides a vehicle-mounted wireless charging device. Figure 1 and Figure 2 , Figure 1 is a schematic overall cross-sectional view of a vehicle-mounted wireless charging device provided in an exemplary embodiment of the present disclosure, Figure 2 yes Figure 1 The in-vehicle wireless charging device 10 includes a housing 11 and a wireless charging module 12 .

[0043] The housing 11 is used to be installed on a vehicle body. The housing 11 includes a carrying portion 111 . The carrying portion 111 is used to carry a device to be charged.

[0044] It should be noted that there are various ways to mount the housing 11 on the vehicle body. For example, the housing 11 can be fixed to the vehicle body via screws. In some embodiments, the housing 11 can be fixed to the vehicle body via a snap-fit structure. In other embodiments, the housing 11 can be fixed to the vehicle body via welding or glue. Specifically, this application does not limit this.

[0045] In addition, the supporting portion 111 has various shapes. For example, the supporting portion 111 may be a plate-like structure. In other embodiments, the supporting portion 111 may be a box-like structure with an opening, etc. Specifically, this application does not limit this.

[0046] Please refer to Figure 2 、 Figure 5 as well as Figure 6 , Figure 5 is a schematic cross-sectional view of a wireless charging module (partial structure) provided in an exemplary embodiment of the present disclosure, Figure 6 yes Figure 5 The wireless charging module 12 includes a circuit board 121 and a transmitting coil 122. The circuit board 121 is disposed on a side of the carrier 111 facing away from the device to be charged. The transmitting coil 122 is electrically connected to the circuit board 121 and is at least partially embedded in the carrier 111.

[0047] It should be noted that, in some embodiments, the transmitting coil 122 can be partially embedded in the carrier 111. There are many ways to achieve that the transmitting coil 122 can be partially embedded in the carrier 111. For example, in some embodiments, a card slot can be provided on the side of the carrier 111 away from the device to be charged, and the transmitting coil 122 can be installed in the card slot to achieve that the transmitting coil 122 can be partially embedded in the carrier 111. In this way, the installation and operation of the transmitting coil 122 are convenient. In other embodiments, a groove can be provided on the side of the carrier 111 away from the device to be charged, and the transmitting coil 122 can be installed in the groove, and the transmitting coil 122 can be fixed in the groove by glue. Of course, the transmitting coil 122 can also be partially embedded in the carrier 111 in other ways, and this application is not limited to this.

[0048] Please refer to Figure 1 、 Figure 3 and Figure 4 , Figure 3 is a cross-sectional view of a carrier portion provided in an exemplary embodiment of the present disclosure, Figure 4 yes Figure 3A partial enlarged schematic diagram at point B is shown. In yet other embodiments, the transmitting coil 122 can be entirely embedded in the carrier 111. There are various ways to achieve this. For example, in some embodiments, secondary injection molding, insert molding, or two-shot injection molding can be used. Specifically, during the injection molding process, the transmitting coil 122 is installed in the mold cavity while the mold is open, and then the mold is closed for injection molding. This allows the transmitting coil 122 to be perfectly integrated with the carrier 111. Of course, the transmitting coil 122 can also be completely embedded in the carrier 111 through other methods, which are not limited in this application.

[0049] In the in-vehicle wireless charging device 10 of the present embodiment, since the device to be charged is placed on the carrier 111 and the transmitting coil 122 is at least partially embedded in the carrier 111, the transmitting coil 122 is placed as close as possible to the receiving coil of the device to be charged. This shortens the distance between the transmitting coil 122 and the receiving coil, enhances magnetic field coupling efficiency, and thus improves charging efficiency and maximum charging power. It also improves charging stability. High charging efficiency means faster charging speeds and higher energy utilization, providing users with a more convenient and efficient charging experience. Furthermore, the embedded transmitting coil 122 reduces the possibility of coil damage due to external factors (such as collisions and vibrations), further improving the safety of the charging process. The embedded transmitting coil 122 also reduces the risk of coil detachment or damage due to improper installation or maintenance. The transmitting coil 122 is embedded in the carrier 111, utilizing the material and structure of the carrier 111 to dissipate heat, optimizing heat dissipation performance. Good heat dissipation performance helps maintain the stable operation of the wireless charging module 12 and extend its service life.

[0050] Please continue to refer to Figure 1 、 Figure 3 and Figure 4 In some embodiments, the transmitting coil 122 is entirely embedded within the carrier portion 111, reducing the external space occupied, making the structure of the wireless charging module 12 more compact, and thereby making the vehicle-mounted wireless charging device 10 compact and beautiful. In addition, the transmitting coil 122 is completely embedded within the carrier portion 111, avoiding direct contact with the outside world and reducing potential safety hazards such as electric shock and short circuits. The transmitting coil 122 is completely embedded within the carrier portion 111, which can ensure that the distance between it and the receiving coil in the device to be charged is minimized, thereby enhancing the magnetic field coupling efficiency and greatly improving the charging efficiency. In addition, the design of the connector 13 makes the electrical connection between the transmitting coil 122 and the circuit board 121 simpler and more convenient, simplifying the installation process.

[0051] In some embodiments, an opening is provided on the side of the carrier 111 facing away from the device to be charged, and one end of the connector 13 extends into the opening and is electrically connected to the transmitting coil 122. The vehicle-mounted wireless charging device 10 also includes a waterproof portion that seals the opening. In this way, the opening provided on the carrier 111 allows one end of the connector 13 to extend into and electrically connect to the transmitting coil 122, providing a convenient electrical connection path between the circuit board 121 and the transmitting coil 122. This design simplifies the connection operation with the transmitting coil 122 and makes subsequent maintenance or repair work easier. By sealing the opening with the waterproof portion, moisture can be prevented from entering the interior of the transmitting coil 122, reducing potential risks caused by safety issues such as short circuits and leakage. The provision of the waterproof portion can also protect the internal transmitting coil 122 from erosion by dust and moisture, thereby improving the durability and reliability of the vehicle-mounted wireless charging device 10.

[0052] It should be noted that there are many types of waterproof parts. For example, in one embodiment, the waterproof part may include a sealing ring. In another embodiment, the waterproof part may also include sealant, and the sealant seals the opening by dispensing.

[0053] Refer again Figure 1 、 Figure 3 and Figure 4 In some embodiments, the carrying portion 111 is provided with a receiving groove 1111, and the receiving groove 1111 is used to accommodate the device to be charged. The bottom of the receiving groove 1111 is inclined. In this way, the design of the receiving groove 1111 provides a clear placement position for the device to be charged, avoiding the sliding or movement of the device during the charging process, thereby improving the stability of charging. The inclined groove bottom design can ensure that the device can be naturally aligned and stably placed in the receiving groove 1111 when placed, further enhancing the stability of charging. The design of the receiving groove 1111 enables users to more conveniently place the device to be charged on the charging device without the need for precise alignment or adjustment of the position, thereby improving the convenience of use. The inclined groove bottom design can also make the device present a more comfortable angle when charging, making it easier for users to view the device screen or perform operations, further improving the user experience.

[0054] It should be noted that the size of the receiving slot 1111 is larger than the size of the device to be charged, so that the device to be charged can be easily taken in and out. In addition, the number of receiving slots 1111 can be set as needed, for example, one, two, or more receiving slots 1111 can be set. Specifically, this application does not limit this.

[0055] Please refer to Figure 5 and Figure 6In some embodiments, the wireless charging module 12 further includes a filter plate 14, which is positioned between the carrier 111 and the circuit board 121. The filter plate 14 primarily functions to reduce electromagnetic interference. In wireless charging systems, electromagnetic interference can affect charging efficiency and safety. By placing the filter plate 14 between the carrier 111 and the circuit board 121, this interference can be effectively reduced, ensuring stable operation of the wireless charging system. By filtering out unwanted electromagnetic frequencies, the filter plate 14 reduces energy loss, thereby improving wireless charging transmission efficiency. This means that within the same charging time, the wireless charging module 12 using the filter plate 14 can deliver more power to the device being charged. The filter plate 14 also protects the charging device from electromagnetic interference. Some sensitive electronic devices may be particularly sensitive to electromagnetic interference, and the presence of the filter plate 14 can reduce potential damage to these devices during wireless charging. By reducing electromagnetic interference and improving transmission efficiency, the filter plate 14 enhances the stability and reliability of the entire wireless charging system. This means that the wireless charging module 12 is less prone to failure and can provide stable charging services under a wider range of conditions.

[0056] Reference Figure 1 and Figure 2 In some embodiments, the filter plate 14 is in close contact with the carrier 111. This close contact between the filter plate 14 and the carrier 111 ensures that electromagnetic signals are not subject to additional interference or loss due to gaps or air layers during transmission, thereby improving the electromagnetic compatibility and filtering effectiveness of the vehicle-mounted wireless charging device 10. Because the filter plate 14 is in close contact with the carrier 111, there is no gap between the filter plate 14 and the carrier 111. This reduces the risk of loosening or detaching the connection between the filter plate 14 and the carrier 111 due to vibration or impact, thereby improving the stability and reliability of the vehicle-mounted wireless charging device 10. The close contact between the filter plate 14 and the carrier 111 allows for a more compact design, thereby reducing the size of the entire charging module. Because the filter plate 14 and the carrier 111 are directly attached, the installation process is relatively simple. Furthermore, if the filter plate 14 needs to be maintained or replaced, it can be quickly removed and replaced, reducing maintenance costs and time.

[0057] Please refer to Figure 1 and Figure 5In some embodiments, the housing 11 is formed with an air duct 112, which is arranged to penetrate the carrying portion 111. The vehicle-mounted wireless charging device 10 further includes a cooling fan 15, which is installed in the air duct 112. In this way, the cooling fan 15 installed in the air duct 112 can actively draw air from the air inlet, and after passing through the wireless charging module 12 and other heat-generating components, the heat is discharged through the air outlet, forming an effective heat dissipation cycle, thereby improving the heat dissipation efficiency of the carrying portion 111 and the device to be charged in the carrying portion 111.

[0058] It should be noted that the circuit board 121 is one of the components in the wireless charging device that generates the most heat. The air duct 112 is arranged adjacent to the circuit board 121. Since the air temperature in the air duct 112 is relatively low, it can exchange heat with the circuit board 121, thereby cooling the circuit board 121, helping to keep the temperature of the circuit board 121 at a relatively low level, thereby ensuring its stable and efficient operation. In addition, the air duct 112 arranged adjacent to the circuit board 121 can promptly remove the heat from the circuit board 121, reducing the temperature of the circuit board 121 and thus extending its service life. In addition, the arrangement of the air duct 112 adjacent to the circuit board 121 can optimize the internal layout of the wireless charging device, making its structure more compact and reasonable. A high temperature environment may cause certain components on the circuit board 121 to short-circuit or catch fire, posing a safety hazard. The air duct 112 arranged adjacent to the circuit board 121 can promptly remove heat and reduce these safety risks.

[0059] In one embodiment, the carrier portion 111 is made of a thermally conductive material with excellent thermal conductivity. Since the air duct 112 extends through the carrier portion 111, heat generated by the transmitter coil 122 can be more efficiently transferred through the carrier portion 111 to the cool air within the air duct 112, achieving heat exchange and thereby lowering the operating temperature of the transmitter coil 122, ensuring its normal operation. This also reduces the temperature of the device being charged. Because the thermally conductive material quickly transfers heat to the cool air within the air duct 112, the temperature of the transmitter coil 122 can be significantly reduced. This reduced temperature helps improve the stability and lifespan of the transmitter coil 122 and reduces the risk of performance degradation or damage due to overheating. When the carrier portion 111 is made of a thermally conductive material, the cool air flowing through the air duct 112 can more effectively absorb the heat transferred from the carrier portion 111, creating effective heat convection and accelerating heat dissipation. Lowering the temperature of the transmitter coil 122 reduces the thermal resistance of the system and improves energy conversion efficiency.

[0060] It should be noted that there are many types of thermally conductive materials. For example, the material of the carrier 111 may include copper, aluminum, carbon material, ceramic material, etc. Specifically, this application does not limit this.

[0061] Reference Figure 5 and Figure 6 In some embodiments, the circuit board 121 includes a component surface 1211 facing the transmitting coil 122, with components mounted on this surface. The wireless charging module 12 also includes a shielding cover 16, which covers the component surface 1211. The other end of the connector 13 passes through the shielding cover 16 and is electrically connected to the circuit board 121. The primary function of the shielding cover 16 is to reduce or eliminate electromagnetic interference generated by components and circuits on the circuit board 121. In the wireless charging module 12, the transmitting coil 122 and components on the circuit board 121 may generate electromagnetic radiation during operation, which may interfere with surrounding devices or systems. By placing the shielding cover 16 over the component surface 1211, the leakage of this electromagnetic radiation can be effectively reduced, minimizing its impact on other devices or systems. By reducing electromagnetic interference, the shielding cover 16 ensures that the wireless charging module 12 operates in a more stable environment. This helps improve the transmission efficiency of wireless charging, making the charging process more efficient and faster. Components on the circuit board 121, particularly sensitive components, may be very sensitive to electromagnetic interference. The presence of shielding cover 16 protects these components from interference from external electromagnetic radiation, thereby extending their service life. The other end of connector 13 passes through shielding cover 16 and is electrically connected to circuit board 121. This design ensures a stable connection between connector 13 and circuit board 121 while maintaining the shielding effect of shielding cover 16. This connection method makes the entire wireless charging module 12 more reliable and stable.

[0062] Reference Figure 1 、 Figure 5 as well as Figure 6In some embodiments, the housing 11 further includes a base 113, which is used to be mounted on a vehicle body. The base 113 is formed with a mounting groove 1131, and the circuit board 121 is located in the mounting groove 1131. The bearing portion 111 is provided in a notch that covers the mounting groove 1131. The bearing portion 111 and the base 113 are detachably connected. In this way, the housing 11 is designed as two detachable parts, the base 113 and the bearing portion 111. This design makes the manufacture, installation, maintenance, and replacement of the vehicle-mounted wireless charging device 10 more convenient. The base 113 is used to be mounted on the vehicle body and can be directly matched with the fixed structure of the vehicle body, simplifying the installation steps. At the same time, the detachable connection between the bearing portion 111 and the base 113 also allows a part of the wireless charging module 12 to be replaced or repaired separately without removing the entire wireless charging module 12. The circuit board 121 is mounted in the mounting groove 1131 formed by the base 113 and is covered by the carrier 111, which prevents dust, moisture, or other contaminants from entering the circuit board 121 area, thereby extending the service life of the circuit board 121. The detachable design of the carrier 111 and the base 113 allows the circuit board 121 or other components to be upgraded or repaired without replacing the entire wireless charging module 12. This not only reduces costs but also increases the flexibility of the in-vehicle wireless charging device 10. By hiding the circuit board 121 in the mounting groove 1131 and covering it with the carrier 111, the wireless charging module 12 is more neat and beautiful in appearance.

[0063] Taking into account that the circuit board 121 will generate heat during operation, in some embodiments, the material made of the base 113 includes a thermally conductive material, so that the heat generated by the circuit board can be quickly transferred to the base, thereby cooling the circuit board. There are many types of thermally conductive materials. For example, thermally conductive materials can include thermally conductive metals, carbon materials, or ceramics. Specifically, thermally conductive metals include copper and aluminum; carbon materials include graphite and carbon fiber. In addition, a thermally conductive auxiliary component 17 is provided between the circuit board 121 and the base 113, and the heat of the circuit board 121 is transferred to the base 113 through the thermally conductive auxiliary component 17, thereby achieving heat dissipation of the circuit board 121.

[0064] It should be noted that there are many types of thermal conductive accessories 17. For example, the thermal conductive accessories 17 may include thermal grease, thermal gaskets, thermal silica gel, graphene and thermal adhesive, etc. Specifically, this application does not limit the type of thermal conductive accessories 17.

[0065] Reference Figure 1 、 Figure 3 and Figure 4 In some embodiments, the supporting portion 111 includes a supporting plate 1112 and an enclosure frame 1113 .

[0066] The carrier plate 1112 is detachably connected to the base 113 and is arranged in a notch that covers the mounting slot 1131. The side of the carrier plate 1112 facing away from the mounting slot 1131 is used to support the device to be charged. This design allows users to easily place the device to be charged on the wireless charging module 12 without worrying about the device's stability. The detachable connection between the carrier plate 1112 and the base 113 facilitates maintenance of the carrier. Users can easily remove the carrier plate 1112 for cleaning or to replace damaged components without disassembling the entire wireless charging module 12. Because the carrier plate 1112 is detachable, users can remove it regularly for deep cleaning to remove accumulated dust and dirt, ensuring the cleanliness and hygiene of the wireless charging module 12. The design of the carrier plate 1112 covering the mounting slot 1131 effectively protects the circuit board 121 and other internal components from impact and damage from external objects. The carrier plate 1112 also acts as an isolation layer, reducing the impact of electromagnetic radiation on the user and other devices inside the vehicle.

[0067] It should be noted that there are many ways to achieve a detachable connection between the supporting plate 1112 and the base 113. For example, in some embodiments, the supporting plate 1112 and the base 113 can be threadedly connected through a screw connection, snap-on connection, pin connection, key connection, etc. Specifically, this application does not limit this.

[0068] Reference Figure 3 and Figure 4 , the enclosure frame 1113 is arranged on the side of the carrier plate 1112 away from the circuit board 121, and the enclosure frame 1113 is arranged around the peripheral side of the carrier plate 1112. In this way, the design of the enclosure frame 1113 can enhance the stability of the carrier plate 1112 and prevent it from shaking or tilting when carrying the device to be charged, thereby ensuring the stability of the device during the charging process. The presence of the enclosure frame 1113 can prevent the device to be charged from sliding or falling off the carrier plate 1112, protecting the device from damage. Especially in a vehicle environment, this design can prevent damage to the equipment caused by vehicle bumps. The design of the enclosure frame 1113 can make the entire charging area look more tidy and beautiful, and enhance the overall user experience.

[0069] Reference Figure 4The carrier plate 1112 is provided with a receiving slot 1111. It is also equipped with multiple retaining ribs 18, which are arranged around the perimeter of the receiving slot 1111. This design of the receiving slot 1111 provides a clear placement area for the device to be charged. This helps users quickly and accurately locate the device to be charged, reducing the risk of misplacement or misalignment. The receiving slot 1111 not only provides a positioning point for the device to be charged, but also provides additional support through the retaining ribs 18 surrounding it. This design makes the device to be charged more stable during charging, reducing the risk of charging interruption or damage to the device due to shaking or collision. The multiple retaining ribs 18 arranged around the perimeter of the receiving slot 1111 ensure that the device to be charged does not slip or move once placed in the slot 1111. Furthermore, when the device to be charged is positioned by the multiple retaining ribs 18, the transmitting coil 122 is aligned with the receiving coil, thereby ensuring charging stability.

[0070] Reference Figure 3 In some embodiments, the enclosure frame 1113 includes a first enclosure panel 11131, a second enclosure panel 11132, a third enclosure panel 11133, and a fourth enclosure panel 11134, which are sequentially connected along the circumference of the carrier plate 1112. The first enclosure panel 11131 and the third enclosure panel 11133 are disposed opposite each other, while the second enclosure panel 11132 and the fourth enclosure panel 11134 are disposed opposite each other. The height of the first enclosure panel 11131 is lower than that of the third enclosure panel 11133, and the heights of the second enclosure panel 11132 and the fourth enclosure panel 11134 increase from the first enclosure panel 11131 to the third enclosure panel 11133. As a result, the relatively low height of the first enclosure panel 11131 forms a low entrance or opening, making it easier for users to approach and reach the device to be charged on the carrier plate 1112. This design makes it more convenient to take the device in and out. The height difference between first and third enclosure panels 11131, 11133, and the progressively increasing heights of second and fourth enclosure panels 11132, 11134, provide ample space for users to access equipment. Users no longer need to worry about collisions or obstructions with enclosure frame 1113, thereby improving operational comfort and efficiency. The progressively increasing heights of second and fourth enclosure panels 11132, 11134 reduce potential obstacles encountered when accessing and placing equipment.
