Onboard mobile phone wired/wireless charger

Abstract

The invention discloses an onboard mobile phone wired / wireless charger comprising a shunt, a transmitter, a receiver and a mobile phone. The shunt is composed of a DC-DC conversion circuit, a Bluetooth module circuit, an electronic switch circuit and a charging mode automatic switching circuit. The transmitter is composed of a DC filter circuit, a transmission control circuit and a transmitting coil assembly. The receiver is composed of a receiving coil assembly, a receiving control circuit and a filtering output circuit. The onboard mobile phone wired / wireless charger is novel in working mode, relatively simple, scientific and reasonable in structure, good in operation universality and convenient to use, and can charge the mobile phone by scanning a code with an APP and the WeChat.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, in particular to a wired and wireless charger for a vehicle mobile phone. Background technique [0002] Today's mobile phones have more and more functions, and the screens are also developing in the direction of higher and higher resolutions and larger sizes, and all these phenomena are facing a very problem-the battery life of mobile phones is getting shorter and shorter. The development of mobile phone batteries has encountered a bottleneck, and battery life has become a huge obstacle to the development of mobile phone functions. With the popularity of smart phone applications and the increase in user frequency, it is generally necessary to charge one or more times a day, and it is necessary to obtain safe and convenient charging in different occasions to meet the demand. In particular, the application of car chargers is becoming more and more extensive. At present, the commonly used...

Problems solved by technology

[0007] However, in practical applications, it is found that since the transmitter and receiver of the existing wireless charging device can only be charged in close contact, and the mobile phone cannot be moved freely during charging, there is still a gap between the charging efficiency and the wired one, although wireless charging solves the problem. The many defects of wired charging do not have the advantages of completely replacing wired charging, and the user's ideal goal cannot be achieved when using it; in addition, the existing wireless charger has a single charging mode, and it is necessary to carry both the transmitter and the power supply when charging. The adapter cannot bring people the safety and convenience of charging in a real sense, and it is not ideal from the perspective of practicality and economy.

[0008] To sum up, the interconnection interference of the existing vehicle-mounted wired charging wires is serious, and the frequent plugging and unplugging of the charging plug affects the service life, and the safety is not high; the charging distance of the existing wireless charging is short, the mobile phone cannot be moved freely during charging, and the charging efficiency is not high enough

The charging method of the two is single, and the use is not easy enough
