Collision-based low-frequency and multi-direction vibration energy collecting device

Abstract

The invention provides a collision-based low-frequency and multi-direction vibration energy collecting device. The collision-based low-frequency and multi-direction vibration energy collecting device is characterized by comprising a shell, a spring, an insulating supporting rod, a magnet, a coil, an annular blocking piece, a mass block and a rope; a hard collision rod protrudes from the surface of the shell; one end of the insulating supporting rod is fixedly connected with the magnet, and the other end of the insulating supporting rod is fixedly connected with the lower base; the magnet is fixed in the shell at a certain distance from the upper bottom surface of the shell; the end, away from the shell, of the hard collision rod is inserted into the blocking piece; one end of the mass block is fixedly connected with one end, opposite to the hard collision rod, of the blocking piece, the other end of the mass block is fixedly connected with one end of the rope, and the other end of the rope is fixedly connected with the upper base; and according to the technical scheme, low-frequency and multi-direction vibration energy in the environment can be converted into high-frequency vibration of the shell and converted into electric energy through the coil, and therefore conversion from external vibration mechanical energy to the electric energy is achieved.

Description

technical field [0001] The invention relates to the field of energy collection, in particular to a collision-based low-frequency, multi-directional vibration energy collection device. Background technique [0002] With the rapid development of wireless communication, MEMS and sensor technology, it has become possible to construct a wireless sensor network including tens of thousands of nodes. Most of the current wireless sensor nodes are still powered by traditional batteries. Although traditional batteries are convenient to use, they have many shortcomings such as regular replacement or charging, serious environmental pollution, etc., which cannot fully meet the power requirements of a large number of wireless sensor nodes. The environment contains energy in the form of light, heat, wind, and vibration, among which vibration energy exists widely, such as the vibration of automobile engines, bridge vibration, human body movement, etc. Collecting environmental vibration energ...

Problems solved by technology

Most of the various vibrations that exist in nature have low frequency, multi-directional and weak characteristics. At present, most electromagnetic vibration energy harvesters can only collect vibration energy in a single direction. Low-frequency multi-directional vibration energy widely exists in
