The connection port 11 can be a threaded hole, at least part of the inner wall of the connection port 11 is provided with an internal thread, and at least part of the outer wall of the metal connector 23 is provided with an external thread 231 matched with the internal thread. In this way, the first support 24 is screwed and fixed with the metal connector 23 through the external thread 231 of the metal connector 23 and the internal thread of the connection port 11, so as to realize the physical connection between the support body 20 and the female seat 10. Then, through the electrical cooperation of the first electric contact end and the second electric contact end, the electrical connection between the support body 20 and the female seat 10 is realized.

[0039] The wireless charging module 21 comprises a wireless charging main board 211 and a wireless charging small board 212, the wireless charging main board 211 is arranged on the first support 24, the wireless charging small board 212 is arranged on the second support 25, the wireless charging main board 211 and the wireless charging small board 212 are electrically connected, and the wireless charging small board 212 is electrically connected with the metal connector 23. Optionally, the wireless charging small board 212 and the metal connector 23 are electrically connected through the first connection wire harness, the wireless charging main board 211 and the wireless charging small board 212 are connected through the second connection wire harness 26, and the first connection wire harness and the second connection wire harness 26 each comprise a matched power line and a data line, so as to realize the data transmission function and the charging function between the female seat and the wireless charging support.

[0040] In this way, the support body 20 is divided into the first support 24 and the second support 24, and the wireless charging main board 211 and the wireless charging small board 212 of the wireless charging module 21 are arranged separately on the first support 24 and the second support 25, so as to avoid that the heat is concentrated in one place, and to avoid that the heat is too high when the electronic device is mounted on the mounting portion 22 for charging.

[0041] Optionally, the metal connector 23 can include a housing made of a non-metal material, such as a plastic housing. The housing is provided on the second support 25, the first electrical contact is provided in the housing, and at least part of the first electrical contact extends out of the housing for plug-in cooperation with the connection port of the female seat. At least part of the first connection wire harness is inserted into the housing and electrically connected to the first electrical contact.

[0042] Referring to Figure 6 As shown, for example, the wireless charging module 21 can also include a wireless charging chip 2111 and a DC-DC voltage conversion chip 2121. The wireless charging chip 2111 is provided on the wireless charging main board 211, and the DC-DC voltage conversion chip 2121 is provided on the wireless charging sub-board 212. The DC-DC voltage conversion chip 2121 is used to convert the power supply voltage of the car machine into a charging voltage suitable for charging electronic devices such as mobile phones.

[0043] The wireless charging module 21 further includes a protection device 2123, a full-bridge circuit 2112, a wireless charging coil 2113, and a demodulation circuit 2114. The full-bridge circuit 2112 is connected between the wireless charging chip 2111 and the wireless charging coil 2113. The wireless charging chip 2111 drives the full-bridge circuit 2112 to realize the wireless charging function of the wireless charging coil 2113. The demodulation circuit 2114 is connected to the wireless charging chip 2111 and is used to extract information transmitted by the data line. The protection device 2123 is connected between the metal connector 23 and the DC-DC voltage conversion chip 2121, and functions as an overvoltage protection device.

[0044] In addition, the wireless charging main board 211 can also be provided with other devices for realizing wireless charging, such as a full-bridge circuit (e.g., a full-bridge MOS) 2112, a wireless charging coil 2113, and a demodulation circuit 2114. The wireless charging sub-board 212 can also be provided with other devices for realizing voltage conversion, such as an inductor 2122 and a protection device (e.g., an EMC device) 2123. Since the related devices for voltage conversion generate a large amount of heat, placing all these devices on the wireless charging sub-board 212 located in the second support 25 can reduce the heat generated by the wireless charging main board 211, effectively reduce the temperature of the wireless charging coil 2113, and thus enable faster wireless charging of electronic devices such as mobile phones. The heat dissipation performance of the vehicle-mounted wireless charging support is optimized.

[0045] It should be noted that the first connection harness for connecting the second support 25 and the metal connector 23, the second connection harness 26 for connecting the first support 24 and the second support 25, and the third connection harness 12 for connecting the female seat 10 and the vehicle controller 91 all include a power positive line (Vbus), a power negative line (Gnd) and a data line (Data pin) that are adapted to each other. That is, in addition to the power positive line (Vbus) and the power negative line (Gnd) for power supply, the data line (Data pin) for data communication is also provided in each harness, thereby forming a set of power supply forms with data communication function.

[0046] In this way, when the support body 20 is inserted into the connection port 11 of the female seat 10 through the metal connector 23, the second electrical contact end and the first electrical contact end are in contact with each other and conductive, power supply is realized through the power positive line (Vbus) and the power negative line (Gnd), and data communication is realized through the data line (Data pin), which not only realizes power supply of the vehicle-mounted wireless charging support and the vehicle machine, but also realizes interaction between the vehicle-mounted wireless charging support and the vehicle machine.

[0047] In some application scenarios, the above-mentioned power supply form can realize the switching control function of the vehicle-mounted wireless charging support, and a button for closing the wireless charging function can be set on the central control screen in the car, and after the user clicks, the vehicle controller receives the control instruction, and the wireless charging chip in the vehicle-mounted wireless charging support is communicated through the data line (Data pin), and the wireless charging chip disables the charging function, so that the charging can be closed.

[0048] In other application scenarios, the above-mentioned power supply form can also realize the forgotten reminding function of the mobile phone and other electronic devices. When the support body and the female seat are connected through the metal connector and the connection port, the female seat is electrically connected with the vehicle controller through the third connection harness, and the device end completes a heartbeat packet upload every certain time (such as 50 ms), and the heartbeat packet can contain the current working state of the vehicle-mounted wireless charging support, such as standby state, charging state, etc. When the car door is opened, if the heartbeat packet received by the vehicle controller shows that the vehicle-mounted wireless charging support is in the charging state, a reminder is triggered, and the central control screen or the sound box issues a reminder, thereby realizing the forgotten reminding function of the mobile phone.

[0049] It should be understood that the present disclosure is not limited to the precise construction that has been described above and illustrated in the accompanying drawings, and that various modifications and changes can be made without departing from the scope thereof. The scope of the present disclosure is only limited by the appended claims.
