Problems solved by technology

[0004] The existing car wireless chargers are not smart enough. When there is a metal object close to the effective charging area, it will cause false discharge and cause unnecessary waste.
The existing vehicle wireless charger produces a large amount of electromagnetic radiation during the charging process, which affects the instruments and meters in the vehicle, affects driving safety, and may cause radiation damage to people
Because the charging process continuously uses the power of the vehicle battery, the vehicle battery is continuously charged and discharged, causing damage to the vehicle battery, and it is not energy-saving and environmentally friendly.
During the driving process of the car, the vibration caused changes the distance between the wireless charger and the mobile terminal, which affects the rate of power transmission between the two, and changes the charging power received by the battery, thus affecting the service life of the battery

Embodiment 1

[0037] like Figure 1~3 As shown, a vehicle-mounted wireless charging device includes a vehicle-mounted housing, a pressure sensor, an alarm indicator light, a fixing device, a solar light-receiving film, a solar control module, an energy storage module, a power control MCU, a high-frequency oscillation circuit, identity verification and system wake-up Module, wireless charging transmitter, mobile terminal wireless charging receiver, mobile terminal charging and discharging capacitor circuit, rectification and filtering circuit, mobile terminal charging control module.

[0038] like image 3 As shown, the vehicle-mounted housing is installed at the vehicle console, the upper surface of the vehicle-mounted housing is provided with a pressure sensor and a fixing device, and the side of the vehicle-mounted housing is provided with an alarm indicator light. The pressure sensor is arranged in the charging area and is connected with the identity verification and system wake-up modu...

Embodiment 2

[0042] A charging method for a vehicle-mounted wireless charging device, based on the vehicle-mounted wireless charging device of Embodiment 1, the specific steps are as follows:

[0043] (1) Wake-up charging step: when the mobile terminal is within 5cm of the wireless charging transmitter or the identity verification and system wake-up module, the mobile terminal charging control module sends a radio frequency identification signal to the identity verification and system wake-up module, and the identity verification and system wake-up module sends a radio frequency identification signal. The verification and system wake-up module receives the signal, determines that the mobile terminal is a wireless charging object, then sends a wake-up signal to the power control MCU, and starts to carry out mobile charging to the mobile terminal; if the identity verification is not passed, the identity verification And the system wake-up module does not send a signal to the power control MCU...

Abstract

The invention discloses vehicle-mounted wireless charging equipment. The vehicle-mounted wireless charging equipment is powered by solar energy and a vehicle storage battery, so that the vehicle storage battery is not damaged and the vehicle-mounted wireless charging equipment is more energy-saving and environment-friendly; the vehicle-mounted wireless charging equipment mainly comprises a solar light-receiving thin film, a solar control module, a power control MCU, a high-frequency oscillation circuit, an identity-authenticating and system-wakening module, a wireless charging transmitting end, a mobile terminal wireless charging receiving end and a mobile terminal charging control module. The vehicle-mounted wireless charging equipment provided by the invention has a function of intelligently recognizing a mobile terminal, can intelligently sleep and intelligently waken, saves electrical energy, does not need a charging interface, and can automatically adjust the charging power.

Description

technical field [0001] The invention relates to a vehicle-mounted device, in particular to a vehicle-mounted dual-power wireless charging device. Background technique [0002] Portable mobile terminals such as smartphones and tablet computers have become indispensable in our daily life. Mobile terminals often suffer from insufficient battery life due to frequent use. In order to ensure that users can charge at any time, car chargers have appeared in the prior art. , but due to the different charging interfaces of different brands of mobile phones, the charging power required for charging is also different. The problem of different charging interfaces can be solved by carrying a matching USB interface charger. Generally, the car is not equipped with a socket for charging, which makes it difficult to solve the problem of different charging power. [0003] Wireless charging refers to charging using the principle of electromagnetic wave induction. It has been widely used due to...
