Problems solved by technology

[0004] First, because there are too many various signal lines, power lines and other cables in the terminal, it is cumbersome to use cable charging
[0005] Second, cable charging requires that the power supply and the terminal cannot be too far apart
[0006] Third, cable charging restricts the user's mobile use of the terminal, such as charging, the user cannot move the terminal at will
[0007] Fourth, the charger interfaces of various manufacturers are inconsistent, and even mobile terminals of different models of the same manufacturer use inconsistent interfaces
thereby limiting the user's charging
[0008] It can be seen from the above points that the existing cable charging method has many disadvantages

Abstract

The invention discloses a terminal and a wireless charging method and system of the terminal. The wireless charging system comprises a wireless charging device and the terminal, wherein the wireless charging device comprises a pulse generator circuit, a pulse modulator circuit and a launching probe; the terminal comprises a receiving module, a charging circuit and a rechargeable battery; the pulse generator circuit generates a high-frequency pulse single; the pulse modulator circuit modulates the high-frequency pulse single; the launching probe converts the pulse single into a vibration wave to be sent out; the receiving module is used for receiving a resonance wave launched by the launching probe and converting the resonance wave into an electric single; and the rechargeable battery is charged by the charging circuit. Compared with the prior art, a mobile terminal can charge the battery by using a wireless resonance wave, thereby overcoming the complication and inconvenience of charging a cable.

Description

technical field [0001] The present invention relates to the technical field of power transmission, in particular to a terminal and a wireless charging method and system thereof. Background technique [0002] The portability of a terminal, especially a mobile terminal, not only requires the terminal itself to be light, compact and easy to carry, but also requires the terminal to be able to maintain a working state for a long time. This can be guaranteed by improving the battery life of the mobile terminal, and can also be guaranteed by charging the mobile terminal. [0003] Mobile terminals popular in the market mainly adopt a cable charging method. There are many inconveniences in cable charging: [0004] First, because there are too many cables such as various signal lines and power lines of the terminal, it is cumbersome to use the cable method for charging. [0005] Second, cable charging requires that the power source and the terminal cannot be too far apart. [0006...
