Utility model content
The purpose of this utility model is to provide a kind of two magnet button self-generating device, can realize actuation of keys and change into electric energy and power to follow-up low consumption circuit.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Device comprises the major part such as working of plastics, non-magnet material coupling part, magnet, yoke, iron core of coil, coiling.Coil winding is on working of plastics, and have through hole in the middle of working of plastics, iron core runs through working of plastics by this through hole.Respectively have one about magnet, its N, S the two poles of the earth contact with four yokes respectively, and namely accompany a magnet respectively in the middle of the yoke of two, the left side and in the middle of the yoke of two, the right, the mode extended by this yoke defines class " U-shaped magnet ".The extremely incorgruous placement of N, S of two magnet in left and right, if namely the magnet N pole on the left side upward, then the magnet S pole on the right upward.The two ends of iron core lay respectively in the middle of four yokes in left and right, are namely in the groove of " U-shaped magnet ".Left and right magnet and yoke are linked together by non-magnet material coupling part, form the button of an one, can relatively move up and down by iron core.
Described iron core is straight iron core, has Ultrathin tabular shape.
Described magnet magnetizing direction is thickness direction, and thickness is 2 ~ 3mm, lays respectively at the right and left of iron core, and two magnet are the extremely incorgruous laying method of N, S, if namely the magnet N pole on the left side upward, then the magnet S pole on the right upward.
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 reverses owing to be there occurs by the magnetic circuit of coil, and therefore comparatively large through the magnetic flux change of coil 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 coil 1, the working of plastics 2 of coiling 1, non-magnet material coupling part 3, magnet 4 and 5, yoke 6,7,8 and 9, iron core 10.Coil 1 is wound on working of plastics 2, and have through hole in the middle of working of plastics 2, iron core 10 runs through working of plastics 2 by this through hole.Magnet 4, about 5 respectively has one, its N, S the two poles of the earth contact with four yokes 6,7,8,9 respectively, namely accompany a magnet 4,5 respectively in the middle of the yoke 6,7 of two, the left side and in the middle of the yoke 8,9 of two, the right, the mode extended by this yoke defines class " U-shaped magnet ".The extremely incorgruous placement of N, S of two magnet 4,5 in left and right, if namely the magnet N pole on the left side upward, then the magnet S pole on the right upward.The two ends of iron core 10 lay respectively in the middle of the yoke 6,7,8,9 of four, left and right, are namely in the groove of " U-shaped magnet ".Left and right magnet 4,5 and yoke 6,7,8,9 are linked together by non-magnet material coupling part 3, form the button of an one, can relatively move up and down by iron core 10.
As shown in Figure 2 and Figure 3, described iron core 10 is straight iron core, has Ultrathin tabular shape.
As shown in Figure 2 and Figure 3, described magnet 4,5 magnetizing direction is thickness direction, and thickness is 2 ~ 3mm, lay respectively at the right and left of iron core 10, two magnet 4,5 are the extremely incorgruous laying method of N, S, if namely the N pole of the magnet 4 on the left side upward, then the S pole of the magnet 5 on the right upward.
Fig. 2, Fig. 3 have also indicated the magnetic induction line situation of change by iron core 10 when button moves up and down.When button is not pressed, iron core 10 contacts with the yoke 7,8 of below, and because yoke 7 contacts with the S pole of magnet 4, yoke 8 contacts with the N pole of magnet 5, and the magnetic induction line therefore now passing through iron core 10 is from right to left, is shown in the dotted arrow in Fig. 2.When button is pressed, iron core 10 contacts with the yoke 6,9 of top, and because yoke 6 contacts with the N pole of magnet 4, yoke 9 contacts with the S pole of magnet 5, and the magnetic induction line therefore now passing through iron core 10 is from left to right, is shown in the dotted arrow in Fig. 3.Just because of the specially incorgruous placement of both sides magnet 4,5, there occurs reversion change by the magnetic induction line direction of iron core 10 in the process, thus make coil 1 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.
