A kind of miniature vibration electric generator
Technical field
The present invention relates to a kind of generator, mainly is a kind of miniature vibration electric generator that is used on the automobile.
Background technology
Generator is a kind of device that is converted to electric energy by mechanical energy, it is a kind of miniature power generating device that generates electricity by manpower that a kind of self-service microgenerator is arranged in the microgenerator, is usually used in the charging to Bicycle Tail Light, walkman, shaver and storage lamp compact electric apparatus.Because miniature power generating device can reduce the pollution of refuse battery to environment, is a kind of energy of green palladium, has been subjected to the general welcome of people.The mechanical energy that the ripple of how automobile being run up and down produces converts electric energy to, and simple in structure, and stable performance is a miniature power generating device of the present invention problem to be solved.
Summary of the invention
The objective of the invention is in order to solve above-mentioned deficiency, and a kind of miniature vibration electric generator that is used on the automobile is provided.
The present invention finishes above-mentioned purpose by the following technical programs.This miniature vibration electric generator mainly comprises housing, is provided with magnet steel in housing, is provided with two groups of high-intensity coils that are mated in the left and right sides of magnet steel, and two groups of coils pick out outside the housing by lead-in wire respectively; Be provided with two groups of springs, spring one end is connected with the upper and lower end face of magnet steel respectively, and the other end is connected with the inwall of housing respectively.
The invention has the beneficial effects as follows: owing to adopted the left and right sides of magnet steel to be provided with two groups of high-intensity coils that are mated, thereby the present invention can realize converting the automobile mechanical energy that ripple produces of running up and down to electric energy, and simple in structure, stable performance.
Description of drawings:
Fig. 1 is a main TV structure schematic diagram of the present invention;
Fig. 2 is an A-A cross-sectional view of the present invention;
Description of reference numerals: housing 1, chute 1-1, coil 2, magnet steel 3, spring 4, spring base 5, lead-in wire 6.
Embodiment:
The invention will be further described below in conjunction with embodiment and accompanying drawing.As depicted in figs. 1 and 2,
This miniature vibration electric generator of the present invention mainly comprises housing 1, is provided with magnet steel 3 in housing 1, is provided with 2, two groups of coils 2 of two groups of high-intensity coils of being mated in the left and right sides of magnet steel 3 and 6 picks out outside the housing 1 by going between respectively; Be provided with two groups of springs 4, spring 4 one ends are connected with the upper and lower end face of magnet steel 3 respectively, and the other end of spring 4 joins with spring base 5 respectively, and spring base 5 is connected with the inwall of housing 1.Have the chute 1-1 that is used to locate of two symmetries on the inwall of housing 1, the front and back biend of magnet steel 3 is installed among the chute 1-1, prevents that magnet steel 3 from seesawing.
Operation principle: magnet steel 3 and arranged on left and right sides are respectively the N utmost point and the S utmost point, when the automobile ripple of running up and down, magnet steel 3 is owing to be subjected to the restriction of chute 1-1, can only move up and down, because the left and right sides of magnet steel 3 is provided with two groups of high-intensity coils 2 that are mated, when magnet steel 3 moves up and down, cutting magnetic line and produce induced current.The induced current that is produced can be used for the charging to compact electric apparatus on the automobile behind over commutation.
