Abstract

The invention relates to a bistable contactless magnetic vibration energy capture device comprising a plurality of bistable piezoelectric sleeves (1). Each bistable piezoelectric sleeve (1) has two stable states including a raised state and a recessed state; first permanent magnets (4) are arrange on the outer walls of the bistable piezoelectric sleeves (1), and the bistable piezoelectric sleeves (1) are mounted on the outer wall of an inner cylinder (5) in a sleeving manner; a plurality of magnetic sleeves (6) sleeve the bistable piezoelectric sleeves (1), are coaxial with the bistable piezoelectric sleeves (1) and are mounted on the inner wall of an outer cylinder (7); second permanent magnets (8) are embedded in the magnetic sleeves (6), and the pole directions of the second permanent magnets (8) embedded in adjacent magnetic sleeves (6) are opposite. The bistable contactless magnetic vibration energy capture device has the advantages that vibration energy is captured through switching between the recessed stable state and the raised stable state of poles due to vibration of the bistable piezoelectric sleeves, collision and friction energy losses can be eliminated in a contactless mode under the action of magnetic force, and accordingly, energy capture is improved.

Description

[technical field] [0001] The invention relates to the technical field of vibration energy capture, in particular to a bistable-based non-contact magnetic vibration energy capture device. [Background technique] [0002] With the development of electronic information technology, mechanical devices are becoming more and more integrated and intelligent, thus showing more excellent performance. Capturing the energy of the mechanical device to power the intelligent functional devices embedded in the mechanical device is not only more energy-saving, but also more reliable without relying on external power sources. Mechanical vibration is the most common mechanical energy that can be captured. At present, the vibration energy capture technology is mainly divided into three types: (1) the electromagnetic type that uses the electromagnetic energy conversion device to convert the vibration mechanical energy into electrical energy; (2) the electrostatic type that uses the electrostatic...
