Abstract
The utility model relates to a solid electronic flash device, which is a flashing signal circuit device used for motorcycle diversion. The utility model is characterized in that the utility model is provided with a pulse signal source circuit and a contactless electronic switch circuit; the utility model has the advantages of compact structure, small size and good performance conformance; the utility model has good shock resistance performance, and therefore, the utility model is particularly suitable for the requirements of field extreme operating conditions and special use environment for motorcycles.
Description
The utility model belongs to a kind of motorcycle and turns to and use the flashing signal circuit arrangement.
Blinker turn signal is one of important structure part of motorcycle safety in utilization.Existing in the market motorcycle turns to uses electronic flash equipment: a kind of is to utilize the different coefficient of thermal expansion principles of bimetallic strip and the thermal slice type electronic flasher made, this structure temperature influence is big, life-span is short, and the dutycycle imbalance is unstable reliable in the course of work; Another kind is that China is from the subsidiary a kind of transistor type electronic flasher of forming oscillatory circuit promotion relay output flashing signal with transistor of external introduction motorcycle technology; this structure generally adopts in the country of advanced technology, but circuit structure complexity, volume increase, humidity resistance and impact resisting vibrating is poor, the relay life-span is short, circuit does not have short circuit and overcurrent protection.
The purpose of this utility model is to propose a kind of integrated form solid-state electronic flasher with stable flashing rate and lowest duty cycle and reliably working and high life at the problem that above-mentioned electronic flasher exists.
In order to solve above-mentioned task, the solution that the utility model adopts is: under the situation of the structure of seal box that still has three sheet metal pins, by a road of power end pin parallel wire, connect two power ends and the timing resistor of time-base integrated circuit through unilateral diode, when the energising end of timing resistor and time-base integrated circuit joins, be connected in series and continue behind another timing resistor to join with the trigger end of time-base integrated circuit and reset terminal and charging capacitor thereof, the time-base integrated circuit output terminal is through current-limiting resistance and connect voltage stabilizing diode and the control pin of two switch integrated circuits; Another road of power end pin parallel wire is connected to the power take-off pin from output terminal respectively behind the power end of two switch integrated circuits; And the earth terminal of charging capacitor, time-base integrated circuit, voltage stabilizing diode and two switch integrated circuits is connected to the earth terminal pin and forms electronic flash equipment.
Solid-state electronic flasher according to the such scheme manufacturing, owing to adopted minimum element, the simplest circuit formula, make it to have higher performance, and on assembly structure, got rid of traditional circuit board fit, brought into play compact conformation, volume is small and exquisite, the characteristics that consistency of performance is good, being convenient to again irritate with the epoxy resin envelope is solid-state devices, and humidity resistance is good, impact resisting vibrating, adapts to the requirement of abominable condition of work of motorcycle and special environment for use especially in the open air.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the circuit arrangement structural drawing according to the solid-state electronic flasher embodiment that the utility model proposes.
