Piezoelectric Power Generation Portable Mobile Phone Charger

Abstract

The invention discloses a piezoelectric power generating portable mobile phone charger, which comprises a casing and a manual coil spring power system, wherein the inside of the casing is separated into an upper space and a lower space; the upper space is a power box; the manual coil spring power system is arranged in the power box; the lower space is a power generating box; a plurality of piezoelectric strain foils, a driving needle and a rectifying and voltage stabilizing integrated circuit are arranged in the power generating box; the driving needle is rotationally connected onto the top of the power generating box through a gear main shaft; the gear main shaft extends into the power box; gear transmission is adopted between the gear main shaft and the manual coil spring power system; the plurality of piezoelectric strain foils are circumferentially arranged at the bottom of the power generating box; the piezoelectric strain foils are positioned on a rotating track of the driving needle. The invention aims at providing the piezoelectric power generating portable mobile phone charger, and aims at solving the problem that a mobile phone cannot be charged in any place at any time; meanwhile, the energy is saved; the environment is protected; safety and economy are realized; the use is convenient and simple.

Description

technical field [0001] The invention relates to a piezoelectric power generation portable mobile phone charger, which does not need to find a power source and a socket when in use, is a self-generated charger, and belongs to the technical field of portable mobile phone chargers. Background technique [0002] At present, all kinds of mobile phone chargers and "power banks" on the market must find a power jack with 220V to charge. There are also restrictions on charging equipment for flying, trains, ships, and waiting places; donkey friends are also very rascals when their mobile phones run out of power in the wild. In short, it is very inconvenient for people who use the charger to charge the mobile phone. [0003] At present, the use of piezoelectric effect to generate electricity is mainly used in various microelectric sensors. Such as: collection and transmission of weather forecast field data, etc. High-power piezoelectric generators (such as piezoelectric power genera...
