Abstract

The utility model relates to a cap produce used for protecting personal safety-a helmet for motor cycle rider. The utility model is a flash helmet witch an oscillation circuit, a driving circuit, a power amplification circuit, a display circuit and a power supply connecting with each other are added on the basis of the existing helmet. The luminescent device is arranged on the outer shell of the helmet and can be flash when switched on. The utility model has the advantages of simple structure, high safety, high security and better effect and is suitable for the psychological need of people. The flash device can be used as other article or environment ornament.

Description

Flash helmet

The utility model relates to personal safe protection's a kind of cap product--Helmet for motorcycle.

The use of motorcycle is increasing, more and more popularizes, is subjected to people's favor.For reducing casualty accident, domestic relevant rules are expressly provided, when requiring the motor driver drives vehicle, must wear the helmet.The existing helmet is generally formed by helmet shell and back boxing, and the helmet shell is placed in the appearance of back boxing.The deficiencies in the prior art part is: it does not glisten and indicates and other decoration device.Motorcycle is the less a kind of motor vehicles of volume, and the little and speed of target is fast, flexibly light and handy, night running especially, though be furnished with lighting fixture on the car body, its east is turned the west and is scurried, when driving a vehicle, often still is difficult for being discovered, noting by people, potential certain hidden danger; The helmet also lacks decoration in addition.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of flash of light indicating device that has is provided, and has both improved the driving at night fail safe, increases the motorcycle helmet product of decorative effect again.

Can reach the purpose of this utility model by following measure.On the basis of the existing helmet, increase the flasher that is formed by connecting by oscillating circuit, drive circuit, power amplifier, display circuit and power supply, it is installed between helmet shell and the back boxing, the luminescent device of display circuit is installed on the helmet shell, and energized can be glistened, and constitutes Flash helmet.

Below in conjunction with accompanying drawing, embodiment content of the present utility model is described in further detail.

Flasher block diagram in Fig. 1, the Flash helmet.

Fig. 2, two groups replace illuminated flasher electrical schematic diagram

Fig. 3, flowing water are chased formula flasher electrical schematic diagram

In the block diagram: (1) oscillating circuit; (2) drive circuit; (3) power amplifier; (4) display circuit; (5) power supply.

Flasher is made up of several parts of vibration, driving, power amplifier, display circuit and power supply at least, and example shown in Figure 2 is two groups and replaces illuminated flasher.

Its oscillating circuit is by 2 CMOS integrated circuit inverter F ₁, F ₂, drive circuit is by 4 CMOS integrated circuit inverter F ₃-F ₆, power amplifier is by triode BG ₁, BG ₂, display circuit is by light-emitting diode group D ₁, D ₂, and resistor-capacitor unit R ₁～R ₆, C forms, and power supply E adopts the dc-battery power supply; F ₁Input pass through R ₁, C and F ₂Output and F ₅, F ₆Input connect F ₁Output, R ₂An end, F ₂Input and F ₃, F ₄Input connect R ₂The other end and R ₁, C serial connection place connects; F ₃, F ₄Output pass through R ₃With BG ₁Base stage, F ₅, F ₆Output pass through R ₄With BC ₂Base stage connect; BG ₁, BG ₂Emitter and E anodally be connected BG ₁, BG ₂Collector electrode pass through R respectively ₉, R ₆With D ₁, D ₂Connect D ₁, D ₂Negative pole be connected with the negative pole of E.Six CMOS integrated circuit inverters, can adopt the CC4069 type, the vibration of being formed, drive circuit, alternately produce the pulse signal of translate phase at its two output, trigger power tube separately in turn, when the output of power discharging transistor is high level, can make the load that is attached thereto---light-emitting diode group D ₁Or D ₂, obtain positive bias-voltage and conducting is luminous; When the power tube output is low level, light-emitting diode group D then ₂Or D ₁Because of instead ending partially.The power tube of two alternations make two groups luminous in turn at the luminous tube of the different colours in helmet shell dead ahead alternately.This is dark, and that are bright, form eye-catching flicker effect.D in this example ₁, D ₂Can respectively select 1～5 light-emitting diode parallel connection in groups.

For obtaining more lucid and more lively, lively flash effect, can on the basis of precedent, suitably increase functional circuit again, as increasing counting and decoding circuit, when adopting different codings, luminous tube just can be luminous by distinct program, and example shown in Figure 3 is exactly to have a kind of flasher that flowing water is chased effect.Wherein: F ₁～F ₁₂Adopt 2 inputs, four NAND gate, CO66 type integrated circuit; C ₁, C ₂The bistable state integrated circuit that adopts the two J-K flip flops of CMOS to form adopts the CO74 type.Luminous tube is arranged in the dead ahead of the helmet.By F ₁, F ₂, R ₁, R ₂, C forms oscillating circuit, changes C and R ₂Parameter scalable frequency of oscillation.Oscillator signal is through F ₃, F ₄Can obtain comparatively ideal square wave after improving waveform, twice shaping.By F ₄The pulse signal of output triggers C ₁, two continuous bistable circuit C ₁, C ₂Upset makes its output Q continuously ₁, Q ₁, Q ₂, Q ₂Current potential change by the binary counting rule.F ₅～F ₈Form decoder, when two inputs of NAND gate were high potential " 1 ", electronegative potential " 0 " just appearred in the output of decoder, and constantly the oscillator signal of input can make each output of decoder be followed successively by electronegative potential and by the certain orientation stepping, as stepping from right to left, pass through F again ₉～F ₁₂Anti-phase, make BG ₁～BG ₄Base stage corresponding also from right to left stepping high potential appears and conducting, luminous tube is luminous one by one successively, chases as flowing water.Four groups of light-emitting diode D ₁～D ₄, can form alternate being arranged in order by 2～3 for every group.

The resistance that is connected in series with luminous tube is the dropping resistor of protection luminous tube.Arrangement mode, the order of luminous tube can be selected arbitrarily between the number of every group of light-emitting diode and group and the group, and selected luminous tube number just determines each simultaneously luminous number, and promptly the pipe while on the same group is luminous.This flasher is all applicable to adult, Children helmet, also can obtain better effects to the decoration in light fixture or other place.

Its relative prior art has following advantage:

1. its simple structure is safe and reliable, need not the set zero clearing in the circuit, and a plugged just can be by selected Program flash indication, and which group is earlier bright, rear, and bright it doesn't matter;

2. increase the flash of light indication, both can improve the driving at night security, have again preferably decorative effect, adapt to people's psychological goal;

3. flasher has certain adaptability, also can be used as the ornament of other article or environment.
