Portable type generating set

Abstract

The invention discloses a portable type generating set. The portable type generating set converts mechanical energy carried by a human body or an animal into electric energy based on an electromagnetic induction theory, and therefore the electric energy is supplied for all kinds of electric appliances or stored in an electrical storage device. According to the portable type generating set, the relative motion between a permanent magnetic set and induction coils is roll movements which is different from the rotating movements or vibrating movements in an existing portable type generating set, therefore, the complexity of the device is reduced greatly, and miniaturization and low cost of the device are easy to achieve. In the portable type generating set, rebound devices are used for enabling the permanent magnet set to be capable of forming multiple times of low-loss reciprocation motions, the energy loss of the whole device is made to be extremely small, and extreme high energy conversion efficiency is achieved. The size of the portable type generating set can be adjusted freely, and the portable type generating set is convenient to use, can be directly fixed to any portion of the human body or the animal, and can also be fixed on objects capable of being worn on the human body or by the animal and objects easy to carry.

Description

technical field [0001] The invention relates to the technical fields of mechanics and electricity, in particular to a portable power generating device. Background technique [0002] As we all know, the activities of the human body or animals carry a lot of mechanical energy. If the energy is converted into electrical energy by appropriate methods and provided to portable electronic devices, the portable electronic devices can be freed from the shackles of battery power. At present, some scientific and technological workers and engineers have adopted some methods to realize the conversion of this mechanical energy to electric energy, such as power generation shoes, power generation backpacks and joint generators. The principles of these portable power generating devices for generating power are various, among which the devices that use electromagnetic induction to generate power have attracted great attention due to their relatively simple structure and low cost.

AI Technical Summary

Problems solved by technology

When using the mechanical energy produced by the human body or animals to generate electricity, if the relative motion between the permanent magnet and the induction coil is to be rotated, some auxiliary mechanisms must be added to realize it, which will greatly increase the complexity of the device

On the other hand, in the portable power generation device, if the relative motion between the permanent magnet and the induction coil is to be vibratory, the natural frequency of the vibrating part is required to be equal to the frequency of walking to achieve resonance. However, due to the human body or animal It is often difficult to achieve resonance due to changes in action status and individual differences
