Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] Such as Figure 1-Figure 9 As shown, a composite vibration energy harvester includes a housing 12 and a cover plate 1. The housing 12 is a hollow cylinder or a cuboid. The top of the housing 12 is provided with a port, and the cover plate 1 is fixed at the port. When the housing 12 When it is a hollow cylinder structure, the outer diameter of the shell can be designed as 30mm, the height of the shell is 32mm, the shell thickness of the shell is 2.5mm, and the cover plate is set as a cylinder with a diameter of 28mm and a height of 2mm, which is convenient to carry , In order to prevent the magnet from the force of the shell and the cover, the shell and the cover are made of non-magnetic materials. The casing 12 is provided with a first permanent magnet 2, an upper pyrolytic graphite plate 3, a first induction coil 4, a first friction layer 5, a second friction layer...

Abstract

The invention relates to a composite vibration energy collector, which comprises a shell and a cover plate, wherein a first permanent magnet, an upper pyrolytic graphite plate, a first induction coil,a first friction layer, a second friction layer, a second permanent magnet, a third friction layer, a fourth friction layer, a second induction coil and a lower pyrolytic graphite plate are arrangedin the shell from top to bottom. One the one hand, the first friction layer and the second friction layer have relative motion to form a friction charge, and the third friction layer and the fourth friction layer have relative motion to form a friction charge, and on the other hand, when the second permanent magnet impacts a piezoelectric plate on the shell, the piezoelectric plate is deformed togenerate piezoelectric charges, and meanwhile, and the change of the surrounding magnetic field can be caused in a movement process of the second permanent magnet, so that the magnetic flux in the first induction coil and the second induction coil changes, and thus induction electromotive force is generated in the coils; and mechanical energy can be effectively converted into electric energy, vibration energy collection can be carried out by adopting a plurality of collection modes, and the energy conversion efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of energy collection, in particular to a composite vibration energy harvester, which can realize energy collection in various ways, convert vibration energy in the environment into electric energy, and improve the efficiency of energy collection. Background technique [0002] As the energy problem becomes more and more severe, the system that needs to collect the energy in the surrounding environment and convert it into electrical energy has become a hot spot of people's research. With the rapid development of MEMS technology and wireless sensor networks in recent years, wireless sensor networks have been used in multiple applications, such as environmental monitoring, medical remote diagnosis and structural monitoring, etc. Currently, chemical batteries are still used in these wireless sensor networks To supply energy for it, but the energy of the battery is limited, and its life is short and polluted, so i...
