[0049] In some embodiments of the present application, a spring wire 500, an overcurrent protection circuit, and an EMC circuit are connected between the power module 300 and the FM transmitter module, the pickup light module, the human-computer interaction module 200, and the DSP audio module.
[0050] In some embodiments of the present application, the power module 300 includes a DC / DC power module 300. The power module 300 can provide multiple protections including overvoltage protection, short circuit protection, overcurrent protection, and overtemperature protection.

[0056] After the vehicle is started, insert the power module 300 into the cigarette lighter port (DC12V-24V power supply), and it is divided into three routes to the power supply through the built-in overcurrent fuse and EMC circuit. The first route is to the IP6520T SOC which integrates multiple fast charging output protocol chips (DCP / QC2.0 / QC3.0 / FCP / HSCP / AFC / MTK PE / PD3.0 / PPS) to charge the PD port of the machine at a maximum of 30W; the second route is to the IP6525T SOC which integrates multiple fast charging output protocol chips (DCP / QC2.0 / QC3.0 / FCP / HSCP / AFC / MTK PE / PD3.0 / PPS) to charge the QC port of the machine at a maximum of 18W; the third route is to the PL8310E The DC-DC step-down regulator IC provides a DC-5.0V power supply to the Bluetooth main chip ATS2853.

[0058] By searching the Bluetooth name of the vehicle-mounted device through the mobile phone Bluetooth and pairing them, the Bluetooth of the mobile phone and the vehicle-mounted device can be bound. The music or phone functions on the mobile phone can be synchronized to the machine, realizing the hands-free function of the mobile phone, reducing the driver's operation of the mobile phone while driving, and ensuring driving safety.
[0059] The FM frequency of the vehicle-mounted device is adjusted to the radio FM frequency consistent with the car audio through instructions. The audio or call signal of the mobile phone is transmitted to the Bluetooth main chip ATS2853 via Bluetooth, and then processed by the internal DSP audio module to form analog signals of the left and right audio channels, which are transmitted to the FM modulation chip QN8027 to form a standard FM-ANT signal, which is radiated outward through the FM antenna. After the car FM receiver receives the FM signal, the sound is played through the car audio.
[0060] Turn on the vehicle's radio and tune it to a blank FM channel, tune the channel of the vehicle-mounted device 10 to the same channel as the vehicle's radio, turn on the mobile phone's Bluetooth to search for the Bluetooth module of the vehicle-mounted device 10, search and click to connect, and after the connection is successful, you can play music, navigate, or make / receive calls and other functions of the mobile phone.
[0061] In a second aspect, the present application provides a vehicle, comprising the vehicle-mounted device 10 in any embodiment of the first aspect of the present application.
