[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0017] The utility model provides a vehicle-mounted wireless dual-charging module, comprising: an interior trim panel 1, a main module 2 and a fan 3.

[0018] The interior panel 1 is installed in the cab, for example, it can be installed in the middle storage box below the front center console of the car. The interior panel 1 and other parts of the car interior can be used as a whole. The front of the interior panel 1 has at least two wireless charging areas; the interior panel 1 also has an air outlet 13 facing the wireless charging area. The main module 2 is fixedly installed on the back of the interior panel 1, and the main module 2 includes a main control board 8, and a first coil unit 4, a second coil unit 5, a micro-control unit 6, and a connector 7 arranged on the main control board 8; wherein the connector 7 is connected to the vehicle-mounted low-voltage battery, and the first coil unit 4 and / or the second coil unit 5 are powered by the micro-control unit 6. The power supply to the first coil unit 4 and / or the second coil unit 5 mentioned here includes at least two modes, one is a working mode for wireless charging, and the other is a communication mode for communicating with the charged device. The communication mode can work with lower power.

[0019] The fan 3 is installed on the main module 2, or on the back of the interior panel 1, and the air duct of the fan 3 is at least connected to the air outlet. The fan 3 is mainly used to cool the charging device, and of course, it can also cool the first coil unit 4 and / or the second coil unit 5. The fan 3 can have two or only one. When two fans 3 are set, Figure 1 As shown, they are located on both sides of the main module 2, respectively, to cool down the devices to be charged in the two charging areas. When a fan 3 is provided, the fan cools down the devices to be charged in the two areas at the same time. Here, the devices to be charged generally refer to mobile phones.

[0020] The first coil unit 4 is a three-coil structure; the second coil unit 5 is a single-coil structure, and a positioning magnet is provided on the second coil unit 5. The general first coil unit 4 is used for wireless charging of Android phones, which can comply with the QI protocol and can provide a maximum working power of 80W. Of course, the specific work will be adjusted according to different mobile phones. The second coil unit 5 is used for wireless charging of Apple phones, which can comply with MPP, EPP (Extended Power Profile), BPP (Base line Power Profile), and can provide a maximum working power of 30W.

[0021] The two wireless charging areas are divided into a first wireless charging area 11 and a second wireless charging area 12, wherein the first wireless charging area has an inclined surface that is higher in the front and lower in the back, and a support step is formed between the bottom of the inclined surface and the interior trim panel 1. The inclined surface of the first charging area 11 and the support step at the bottom can ensure that the position is fixed after the mobile phone is placed and will not move. Preferably, the inclined surface of the first wireless charging area 11 has an anti-skid pad and / or anti-skid ribs. The second wireless charging 12 can fix the mobile phone by a positioning magnet.

[0022] The air outlet 13 is formed on the supporting step, blowing air from the bottom of the mobile phone to cool the mobile phone. For the second wireless charging 12, the air outlet 13 can be directly formed on the mobile phone supporting surface to directly blow air to the mobile phone to cool it down.

[0023] The first wireless charging area 11 corresponds to the first coil unit 4, which is mainly used for Android phones, and the second wireless charging area 12 corresponds to the second coil unit 5, which is mainly used for Apple phones. However, Android phones and Apple phones can interchange charging areas, that is, the first wireless charging area 11 can reduce the working power to support the use of Apple phones. The second wireless charging area 12 can provide wireless charging function for Android phones.
