Generating set for lamp switches based on hollow piezoelectric transducer

Abstract

The invention relates to a generating set for lamp switches based on a hollow piezoelectric transducer, belonging to the technical field of new energy and power generation. The end part of an upper shell is fixedly connected with a hinge pin; a circuit board is fixedly connected with a support inside the upper shell; a pressing plate is fixedly connected with the inside of the upper shell by bolts; an upper surface is provided with a switching push button; a lower shell is provided with connecting lugs; a guide plate is fixedly connected with the lower shell by bolts; a force-applying hinge pin is slidably connected with the inside of the guide plate; 1-10 hollow piezoelectric transducers are arranged in the lower shell; the pressing plate is connected with the force-applying hinge pin in a compression mode; the force-applying hinge pin is adhesively bonded with a conductive rubber lock block which is adhesively bonded with piezoelectric vibrators in the hollow piezoelectric transducers; and the upper shell and the lower shell are hinged with holes on the connecting lugs. The generating set has the advantage that the piezoelectric vibrators generate electricity by pressing the push button on the shell to drive the shell and the switching control is implemented at the same time, thus conforming to habits to operate the lamp switches.

Description

technical field [0001] The invention belongs to the technical field of new energy and power generation, and specifically relates to a power generation device for a lamp switch based on a hollow piezoelectric transducer, which is used for power supply of a lamp remote control switch. Background technique [0002] Patents for using piezoelectric generators to construct battery-free remote controllers and lamp switches have been applied for in China, but due to the shortcomings and disadvantages of the generator structure and power generation capacity, there has been no successful promotion and application so far. For example, Chinese Invention Patents 200520111441.5 and 00817016.9 respectively introduced two types of piezoelectric generators based on strike and impact, and Chinese Invention Patent 200520008424.9 introduced a generator that uses buttons to apply force to piezoelectric elements and its remote control. In the above-mentioned patents, a single piezoelectric vibrat...
