Automatic power generation device of pedestrian stairs

Abstract

The invention provides an automatic power generation device of pedestrian stairs. The automatic power generation device comprises stair pedals and a plurality of power generation units arranged at the bottoms of the stair pedals; a bracket of each power generation unit is fixed on a bottom plate, and the top of the bracket is fixedly connected with a bracket end cover; the top of a vertical moving pin is fixedly connected to an upper plate, the vertical clearance of the lower end of the vertical moving pin passes through the bracket end cover, and a limiting sleeve is arranged on the bracket end cover; a pressure spring is sleeved on the vertical moving pin and positioned between the upper plate and the bracket end cover; a limiting pin and multilayer strip permanent magnets are fixedly arranged at the position where the vertical moving pin is positioned below the bracket end cover; corresponding to the end face of the magnetic pole of each strip permanent magnet, an electromagnetic coil wound on an iron core is embedded into the bracket; a clearance is formed between the end face of the magnetic pole of the permanent magnet and the iron core; and all the electromagnetic coils of the power generation units are connected in series and then connected with an output terminal. When pedestrians tread on the stair pedals, the strip permanent magnets move up and down, the electromagnetic coils generate induced electromotive force and current, and walking of the pedestrians is used for generating power.

Description

technical field [0001] The invention relates to an automatic power generation device for pedestrian stairs, which belongs to the technical field of vibration power generation. Background technique [0002] In the existing vibration power generation device, the vibration of the machine or the vibration of the road is used to convert the mechanical vibration energy into electrical energy through electromagnetic coils or piezoelectric crystals. Due to the small vibration amplitude, low power generation efficiency and low power, it is difficult to meet the actual Power requirements. Contents of the invention [0003] The object of the present invention is to provide an automatic power generation device for pedestrian stairs that can overcome the above defects, has high power generation efficiency, relatively large power and simple structure. Its technical solution is: [0004] An automatic power generation device for pedestrian stairs, characterized in that it includes stair...
