Abstract

An electromagnetic vibration power generation device comprises a casing, wherein a vibrator capable of vertically sliding is arranged in the casing. The vibration power generation device further comprises four induction coils, a front magnet yoke, a back magnet yoke, a left magnet yoke, a right magnet yoke, an upper magnet yoke support and a lower magnet yoke support. The casing is a cylinder with a bottom and is made of non-magnetic materials, four guide rails are evenly distributed on the inner lateral wall of the cylinder, the vibrator can be slidingly arranged on the guide rails, and the smallest dimension of each guide rail in the radial direction is smaller than the radius of the top of each protruded square tooth on each magnet yoke. The lower magnet yoke support, the magnet yokes, the vibrator, the upper magnet yoke support, the induction coils and yoke tops are arranged in the casing from bottom to top in sequence. The four magnet yokes are made of soft magnetic materials and symmetrically distributed in an adjacent mode along the circumferential direction of a cavity of the casing, the two magnet yokes at opposite positions are completely identical, and the square teeth of the adjacent magnet yokes are distributed in a convex-concave stagger mode. The electromagnetic vibration power generation device is small in vibration resistance, high in magnetic circuit utilization rate and high in power generation efficiency.

Description

technical field [0001] The invention relates to a vibration power generating device. Background technique [0002] In recent years, people's interest in new environmentally friendly power supply methods has been increasing. Energy harvesting technology is one of the most promising methods to replace traditional power supply methods. It has attracted the attention of many scholars. For example, it can collect magnetic energy in the environment for wireless sensor network nodes. use. Vibration is ubiquitous in nature, such as waves fluctuating, people vibrating up and down when walking, cars bumping, branches swaying with the wind, etc. The vibration energy is usually ignored or absorbed by shock absorbers and other equipment. If the energy generated by vibration is collected and replaced by batteries to power some low-power devices such as micro-sensor network nodes or Internet of Things nodes, it will not only reduce the environmental pollution caused by batteries, but also...
