Mobile phone charged through touch

Abstract

The invention discloses a mobile phone charged through touch. The mobile phone comprises a piezoelectric film, a voltage conversion module, a charge management module and a mobile phone auxiliary battery. The piezoelectric film is arranged on the screen of the mobile phone and used for converting pressure generated when users touch the screen of the mobile phone into electric energy. The input end of the voltage conversion module is connected with the electric energy output end of the piezoelectric film, the voltage conversion module is used for converting small voltage output by the piezoelectric film into the voltage suitable for charging of a mobile phone battery, and the voltage output end of the voltage conversion module is connected with the mobile phone auxiliary battery through the charge management module. The charge management module is used for charging management of the mobile phone rechargeable battery. The mobile phone auxiliary battery is used for storing the electric energy. The mobile phone has the advantages that the piezoelectric film is arranged and can convert the pressure generated when the users touch the screen of the mobile phone into the electric energy, the voltage conversion module is combined for charging the mobile phone, operation is easy and practicable, charging is convenient, the service time of the mobile phone is prolonged, and the piezoelectric film is a transparent piezoelectric film so that the display effect of the original screen of the mobile phone can be guaranteed.

Description

technical field [0001] The invention relates to a mobile phone, in particular to a touch-charging mobile phone. Background technique [0002] As an essential communication tool for modern people, mobile phones have become more and more popular. The use time of mobile phones has always been a concern of people. In order to prolong the use time of mobile phones, the methods adopted are generally to save energy consumption or increase battery capacity, but these two methods have certain limitations. In recent years, people have begun to study the self-charging of mobile phones. The existing self-charging methods mainly include solar charging, light energy charging, and manual charging. Manual charging mainly refers to charging the mobile phone through a common charger connected to an external power source. If there is no external power source, the charging cannot be completed. In addition, When the user goes out, it will be inconvenient to carry; solar or light energy chargin...

The existing self-charging methods mainly include solar charging, light energy charging, and manual charging. Manual charging mainly refers to charging the mobile phone through a common charger connected to an external power source. If there is no external power source, the charging cannot be completed. In addition, When the user goes out, it will be inconvenient to carry; solar energy or light energy charging is to convert solar energy or light energy into electrical energy, and then charge the mobile phone. The charging of the mobile phone can only be completed under the condition of ambient light, and the charging efficiency is low and the cost is high
