Abstract

The invention relates to a transverse vibration electricity generator based on telescopic piezoelectric vibrators and belongs to the technical field of electricity generation. An end cover is installed at one end of the cylinder wall of a shell through a screw, the bottom wall of the shell and the end cover are each provided with a plurality of mounting holes uniformly, the number of the mounting holes in the bottom wall of the shell is equal to that of the mounting holes in the end cover, the two ends of each long pin are mounted in the corresponding mounting holes, each long pin is sleeved with a long pin sleeve, each long pin sleeve is in riveted connection with a metal plate with an arc-shaped protrusion, each metal plate and a piezoelectric plate adhering to the corresponding arc-shaped protrusion constitute the corresponding piezoelectric vibrator, and the other end of each metal plate is in riveted connection with a short pin sleeve. Pin holes are formed in the upper wall of a mass block, and threaded holes are formed in the lower wall of the mass block. Short pins are mounted on the mass block through the pin holes and the threaded holes, the short pin sleeves are mounted on the mass block in a hinged mode through the short pins, and rolling balls are embedded in the end faces of the upper wall and the lower wall of the mass block. The transverse vibration electricity generator has the advantages that the telescopic piezoelectric vibrators are hinged to the shell and the mass block and restrain one another from telescopic deformation, reliability is high, the low frequency characteristic is good, electricity generation capacity is high, and vibration direction adaptive capacity is high.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a transverse vibration generator based on a telescopic piezoelectric vibrator, which provides real-time energy supply for micro-power electronic products and wireless sensor monitoring systems. Background technique [0002] The micro-generator constructed by using piezoelectric ceramic materials to recycle environmental vibration energy is considered to be an effective means for real-time self-power supply of portable micro-power electronic products and remote implanted sensor monitoring systems. Although some types of vibrating piezoelectric generators have been applied in reality, their adaptability to the vibration environment, reliability and energy conversion efficiency are still relatively limited, which is not conducive to the development of piezoelectric vibration power generation technology. Promote the application further. For the vibrating piezoel...
