Abstract

The utility model discloses an iron core surrounding type's button is from power generation facility. The device is including straight iron core, surrounding type iron core extension, coil, magnet, yoke. Coil winding is on straight iron core, and the one end of straight iron core is connected with surrounding type iron core extension, and the other end of straight iron core is located in the middle of two yokes. Accompany a magnet in the middle of two yokes. Magnet and yoke form the button an of an organic whole, but looks alignment with iron core reciprocates. Reciprocate when the button, the iron core will be respectively with the yoke contact of top and below, feel the line through the magnetism of iron core this moment and take place the reversal in this course to make the coil produce induced electromotive force. Surrounding type iron core extension can strengthen the intensity of overflow tank through straight iron core to the induced electromotive force that the reinforcing produced. The utility model discloses be used for little energy of button to generate electricity, simple structure, it is small, applicable in multiple buttons that needs such as wireless switch from the occasion of generating electricity.

Description

A kind of button self-generating device of iron core circulating type

Technical field

The utility model relates to a kind of self-generating device, especially relates to a kind of button self-generating device with iron core circulating type.

Background technology

Along with the development of technology, increasing dairy products is marched toward wireless penetration and miniaturization, and powerup issue wherein becomes the key issue needing to solve.Such as traditional switch is just remote controlled, wireless switching that is removable, that exempt to connect up replaced, and in the wireless switching had at present, still adopt battery to be that circuit in switch is powered, the restricted lifetime of battery, need to change after a certain period, this have impact on the use of switch to a certain extent, and simultaneously useless battery also pollutes the environment.In this application scenario, the mechanical action of switch key can be converted into electric energy by button self-generating device, thus powers for subsequent conditioning circuit, it solves the problem of wireless switching electric energy supply, makes the use of wireless switching convenient.This touch-tone self-generating device also can be used for other multiple occasion such as automobile key, hand-held remote controller, and the scope of application is very extensive.Therefore, market is that plurality of devices product carries out self-powered in the urgent need to the button self-generating device of microminiaturization.

Utility model content

The purpose of this utility model is to provide a kind of miniature button self-generating device of iron core circulating type, can realize actuation of keys change into electric energy give follow-up low consumption circuit power.

For achieving the above object, the technical solution adopted in the utility model is as follows:

Device comprises straight iron core, circulating type iron core extension, coil, magnet, these key components of yoke.Coil winding is on straight iron core.N, S the two poles of the earth of magnet contact with upper and lower two yokes respectively, and namely accompany magnet in the middle of two yokes, the mode extended by this yoke defines class " U-shaped magnet ".The two ends of straight iron core are positioned in the middle of upper and lower two yokes, are namely in the groove of class " U-shaped magnet ".Magnet and yoke link together, and form the button of an one, can move up and down by relatively straight iron core.Circulating type iron core extension can strengthen the magnetic flux density by straight iron core, thus strengthens the induced potential produced.

Described circulating type iron core extension can adopt three kinds of different modes in reality is implemented: first kind of way is only surround long and high two leptoprosopy formed of straight iron core; The second way is two wide that only surrounds straight iron core length and wide composition; The third mode is both surrounded straight iron core length and two wide that also surrounds straight iron core length and wide composition while of high two leptoprosopy formed.

The beneficial effects of the utility model are:

Structure is simple, and the number of components that device comprises is few, and the production and processing of all parts is easy, and assembling is simple; Volume is little, and all part dimensions are all very little, and can be integrated into wireless switching etc. needs in the product of button self-generating device; The induced electromotive force produced is large, once reverse owing to be there occurs by the magnetic circuit of straight iron core, employing circulating type iron core extension strengthens the magnetic flux density by straight iron core simultaneously, therefore comparatively large through the magnetic flux change of the coil be wound on straight iron core in the moment of button, the induced potential that can produce is also larger.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described further.

As shown in Figures 1 to 3, the utility model device comprises straight iron core 1, circulating type iron core extension 2, coil 3, magnet 4, yoke 5,6; Coil 3 is wound on straight iron core 1; N, S the two poles of the earth of magnet 4 contact with upper and lower two yokes 5,6 respectively, and namely accompany magnet 4 in the middle of two yokes 5,6, the mode extended by this yoke defines class " U-shaped magnet "; The two ends of straight iron core 1 are positioned in the middle of upper and lower two yokes 5,6, are namely in the groove of class " U-shaped magnet "; Magnet 4 and yoke 5,6 link together, and form the button of an one, can move up and down by relatively straight iron core 1.

As shown in Figure 3, the object of described circulating type iron core extension 2 strengthens the magnetic flux density by straight iron core, and it can adopt three kinds of different modes in reality is implemented: first kind of way is only surround long and high two leptoprosopy formed of straight iron core (1); The second way is two wide that only surrounds straight iron core (1) length and wide composition; The third mode is both surrounded straight iron core (1) length and two wide that also surrounds straight iron core (1) length and wide composition while of high two leptoprosopy formed.

Fig. 2 shows the signal that magnet 4 and yoke 5,6 move up and down.Magnet 4 and yoke 5,6 form the button of an one.When magnet 4 and yoke 5,6 move up and down once, by the magnetic induction line of straight iron core 1 in the process by produce first power to reversion change, the magnetic flux namely by being wound in the coil 3 on straight iron core 1 will change, thus make coil 3 produce induced potential.Micro-energy of button is used for generating electricity by the utility model, and structure is simple, and volume is little, pollution-free, is applicable to the multiple occasions needing button self-generating device such as wireless switching.
