Charging method and charging apparatus for mobile terminal

Abstract

Embodiments of the invention disclose a charging method and a charging apparatus for a mobile terminal. The charging method comprises the steps that the charging apparatus comprises a piezoelectric film sensor; after a pressing area for pressing the piezoelectric film sensor is obtained, whether the pressing area is larger than a preset area or not is judged; if so, the action force for pressing the piezoelectric film sensor is converted into electric energy, and the voltage of the electric energy is adjusted into a first voltage that is matched with the charging parameters of a battery of the mobile terminal; and finally the adjusted electric energy is used for charging the battery. Through the adoption of the embodiments of the charging method and the charging apparatus, a user can wear the charging apparatus in places with relatively obvious muscle activities, such as an arm, so as to convert pressure of the arm sensed by the piezoelectric film sensor into electric energy for conveniently charging the battery of the mobile terminal; and in addition, the control apparatus is portable and capable of realizing continuous charging, so that the user experience is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a charging method and a charging device for a mobile terminal. Background technique [0002] With the rapid development of electronic technology, mobile terminals such as smartphones and tablet computers have become indispensable tools in people's lives. People can use mobile terminals to watch videos, listen to music, process documents, play games, etc. However, as the functions of the mobile terminal increase, its power consumption is faster and faster. Therefore, in order to prolong the use time of the mobile terminal, the generally adopted method is to increase the battery capacity or save power consumption, but both methods exist. Certain limitations. In recent years, people have begun to conduct research on charging the batteries of mobile terminals. The existing charging methods include: connecting the charger to an external power source. If there is no external power...

However, as the functions of the mobile terminal increase, its power consumption is getting faster and faster. Therefore, in order to prolong the use time of the mobile terminal, the general method is to increase the battery capacity or save power consumption, but both of these methods exist. certain limitations

In recent years, people have begun to conduct research on charging the battery of the mobile terminal. The existing charging methods include: connecting the charger to an external power source, if there is no external power source, the charging cannot be completed; using solar energy charging (converting solar energy into electrical energy ), but this needs to be charged in a sunny environment
