Abstract

The utility model provides a non-power supply electronic flash device for a bicycle. The power generation theory by the magnetic field induction is adopted by the utility model, so a practical non-power supply electronic flash device is designed. The utility model is not only suitable for the turning indication of the bicycle but is also suitable for the flashing indication of various toys. The utility model has the advantages of simple structure, small volume, low cost, long service life, no power consumption, etc.

Description

Non-power supply electronic flash device for bicycle

The electronic flash that turns to indication, toy of present all kinds of flashing feature such as vehicle all is electric energy to be provided or to be cried active driving by battery or alternating current, that is, flash of light comes from the power consumption of battery or alternating current.

The purpose of this utility model provides a kind of non-transformer bicycle electronic flash equipment.

The purpose of this utility model realizes in the following manner, in a plastic casing, adorn two groups of E sections stamens, be wound with coil on the iron stamen, vertically lay a permanent magnet at the opening part of E sections stamen, when bicycle walking because of road is uneven ripple can take place to run up and down, like this, permanent magnet just moves up and down at iron stamen place, the moving of magnetic field just induces electric current and to light semiconductor light-emitting-diode on coil, because what magnetic field mobile induced is that positive half cycle of alternating current or negative half period all have a semiconductor light-emitting-diode to light, so be connected in parallel by two mutual both positive and negative polarities of semiconductor light-emitting-diode.As long as permanent magnet ceaselessly moves being wound with on the iron stamen of coil, electric current will constantly produce for semiconductor light-emitting-diode luminous.As long as two groups of semiconductor light-emitting-diodes are installed on the turning of bicycle lamp position,, lead to the electric current of respectively organizing semiconductor light-emitting-diode and just can realize non-transformer bicycle electronic flash equipment of the present utility model by a switch control.

Figure of description (1) is a circuit diagram of the present utility model;

Figure of description (2) is a structural representation of the present utility model.

The utility model will be further described with reference to Figure of description:

Coil (5) being fixed in the plastic casing (1) of two E sections stamens (4), makes its opening staggered relatively, and keeps certain space on E sections stamen (4).The permanent magnet (6) that has the hole is through on the major axis (3), two ends in permanent magnet (6) perforate respectively add a spring (2), then major axis (3) band permanent magnet (6) spring (2) is placed between the two iron stamens (4) in the lump, the same shell of major axis (3) (1) fixes.Not being advisable not rub mutually in gap between iron stamen (4) and the permanent magnet (6), rocks shell (1) gently, and permanent magnet (6) can move on major axis.

Coil (5) is connected by lead and two groups of semiconductor light-emitting-diodes (7), and every group of semiconductor light-emitting-diode (7) is again to be connected in parallel by two mutual both positive and negative polarities, has K switch control to lead to the electric current of respectively organizing semiconductor light-emitting-diode in the circuit.

Embodiment 1:

The utility model by specification accompanying drawing (2) is installed, be fixed in the bicycle handle bar, two groups of semiconductor light-emitting-diodes are made left and right sides turning indicator respectively, by specification accompanying drawing (1) circuit diagram connects, as long as bicycle walking operating switch K just can allow indicator lamp glisten.

Embodiment 2: the utility model by specification accompanying drawing (2) is installed, be fixed in the toy for children, as cloth doll, toy etc., two semiconductor light-emitting-diodes of one group are made two eyes of animal respectively, by specification accompanying drawing (1) is turned on the electricity, shake toy gently, two semiconductor light-emitting-diodes will sparkle.

Non-transformer bicycle electronic flash equipment of the present utility model, compare with existing all kinds of active flashing features have simple in structure, volume is little, long service life, and saves electric energy, can be used in the various flash of light utensils.

(1) described in the specification sheets is shell, and (2) are springs, and (3) are major axis, and (4) are E sections stamens, and (5) are coils, and (6) are permanent magnets, and (7) are quartz conductor conductor light-emitting diodes.

Except that the technical characterictic described in the specification sheets, be prior art.

Claims
