Fig. 1 is an external view of an in-vehicle wireless charging device according to the present invention. Fig. 2 is an exploded view of the vehicle-mounted wireless charging device according to the present invention. Fig. 3 is an installation diagram of the vehicle-mounted wireless charging device according to the present invention. As shown in fig. 1 to 3, the vehicle-mounted wireless charging device of the present invention includes a housing, a coil assembly and a PCB assembly, the coil assembly and the PCB assembly are disposed in the housing, the housing includes a base housing 1 and an upper cover plate 2, the coil assembly includes a coil 3, a coil plate 4 and a coil support 5, and the PCB assembly includes a PCB plate 6 and a connector 7 disposed on the PCB plate. In the housing, the coil assembly is located above the PCB assembly.

Specifically, regarding the coil assembly, the coil 3, the coil plate 4, and the coil support 5 are sequentially stacked, and the coil plate 4 is disposed between the coil 3 and the coil support 5. The coil (inductor) 3 and the coil plate 4, and the coil plate 4 and the coil support 5 may be fixed by double-sided tape or glue. The coil 3 is connected with the PCB 6 and connected with a vehicle-mounted power supply through a connector 7 on the PCB 6 to generate current, so that the coil in the nearby electronic equipment generates induced current correspondingly, thereby charging the electronic equipment (such as a mobile phone) to be charged. The coil (also called wireless charging coil) 3 is flat to reduce the vertical height, so that the design is light. The coil plate 4 is made of PC95 MnZn, has low resistivity and is conductive, mainly plays a role in isolating a magnetic field and synchronously plays a role in magnetic conduction. Here, the wireless charging device of the present invention adopts the coil plate 4 made of PC95 MnZn, replaces the traditional conductive magnetic isolation material, and reduces the volume of the wireless charging module as much as possible under the condition of meeting the conductive performance requirement, so that the whole device has compact volume, and the application range of the device is expanded. The coil support 5 functions to support the coil 3 and the coil plate 4.
