Portable power supply equipment

Abstract

The invention belongs to the technical field of power supply equipment and particularly relates to portable power supply equipment which comprises an energy storage battery device, a pressure and electric energy conversion device, a voltage and current integration device and a frame supporting device. The energy storage battery device is fixedly connected with the frame supporting device; the pressure and electric energy conversion device and the frame supporting device are connected with each other and arranged above and / or below the energy storage battery device; and the voltage and current integration device is connected with the energy storage battery device and the pressure and electric energy conversion device. Compared with the prior art, under the condition that the portable power supply equipment is not provided with an external power supply for supplementing the electric energy, the piezoelectric material can convert the mechanical energy into the electric energy directly through shaking and other mechanical actuations, the electric energy is integrated by the voltage and current integration device, stored into a battery and converted into the chemical energy. Under the condition that no standby battery or power supply needs to be prepared, the electric energy of a power supply can be supplemented so that electronic equipment can work normally for a long time.

Description

technical field [0001] The invention belongs to the technical field of power supply equipment, and in particular relates to a portable power supply equipment. Background technique [0002] Portable electronic devices are widely used in modern society, involving communication, entertainment, office and other fields, and play a pivotal role in our life and work. Electronic equipment has higher and higher requirements for power supplies. Traditional power supplies are constantly upgrading the energy density of the power supply itself to meet the needs of electronic equipment while maintaining multiple functions and working for a long time. [0003] In the case that charging devices cannot be provided outdoors, it is usually necessary to prepare backup batteries or backup power sources to ensure the normal operation of electronic devices. The use of these backup devices will complicate the original simple life to a certain extent. [0004] In view of this, it is indeed necessar...
