Abstract
The present invention adopting electronic circuits, solves the problems of triode switch circuit and short-circuit automatic protection circuit. Its main technique is characterized by that adopting high power triodes to form switch circuit to form flashing signal and using thyristor installation to form short-circuit overcurrent protection circuit. Said invented product mainly is used in direction signal light system of automobile and other motor vehicles.
Description
Contactless electronic flasher of automobile (hereinafter being called this product) by electronic circuit and one-tenth, belongs to electronic technology field.Belong to technical field of automotive electronics specifically.
This product is invented by the inspiration of " flasher electronic flasher " literary composition.(stating Beijing electronics newspaper third edition on January 7th, 1993 in detail), service life, reduction fault rate in order to increase the flasher Der Blink und Abblendschalter guarantee that better the purpose of traffic safety is invented.
This product is mainly by switch circuit that aerotron autoexcitation and large power triode are formed; The short circuit automatic protection circuit; Music warning circuit three parts are formed.After this product energising, by aerotron and around the aerotron self-maintained circuit that constitutes of element, produce oscillator signal output, directly triggering is by two compound switching valve work of forming of large power triode.Make the switching valve conducting, end, one open-one close forms switch circuit.Drive load---bulb, one bright one goes out forms flash of light.(can be by the ON time of adjusting switch pipe, flash rate is controlled in 65 times-120 underranges of per minute, if switching valve is changed into 200W high-power darlington pipe, carrying load ability two enhancing, power boostings greatly) just in switching valve work, in the time of flash of light just, the music warning circuit also obtains electricity and works, by piezoelectric patches send a first interesting to listen to electronic music, to show alarm.When the Der Blink und Abblendschalter load was short-circuited, electric current will increase in the steering indicating light circuit, surpassed rated current.Current foldback circuit (short circuit automatic protection circuit) is just work also, and the short circuit indicator lamp is luminous, and the silicon control conducting causes the self-maintained circuit failure of oscillation, and the dead-beat signal output forces switch circuit to quit work.Switching valve is not burnt out, thereby protected switching valve, protected whole Der Blink und Abblendschalter, Der Blink und Abblendschalter is increased service life widely.So just form long life, a contact pointless, the music warning function has been arranged, had short circuit to protect and be with short circuit deixis, high-power new invention Der Blink und Abblendschalter automatically.
This product is compared with old-fashioned relay system Der Blink und Abblendschalter, and it is many to have function, advantages such as long service life, self-insurance ability are strong, contact pointless, power is big, working stability is reliable, and fault is few.And also have that cost is low, the big advantages such as (6V-24V) of operating voltage range.
Great majority use relay system steering indicating light Der Blink und Abblendschalter on the automobile now, and the long slightly relay that just damages easily of this Der Blink und Abblendschalter, work-hours burns out relay contact.When particularly load is short-circuited, as the trafficator cable bonding, turn to the light bulb filament short circuit, will burn out relay contact, whole Der Blink und Abblendschalter damages, and causes waste to influence the safety of driving at once.I have adopted breakerless transistor switching circuit for this reason, replace relay work (the certain switching valve in the switch circuit, the large power triode that must service property (quality) reaches a standard), and have set up the short circuit automatic protection circuit.Because of Der Blink und Abblendschalter has not had the contact, Der Blink und Abblendschalter electricity in service life will increase like this, and fault also will reduce.When if the Der Blink und Abblendschalter load is short-circuited, because of having set up the short circuit automatic protection circuit, the self-insurance ability is arranged, so can not burn out Der Blink und Abblendschalter.Like this, just increased the service life of Der Blink und Abblendschalter widely.I think that above description is the best way that realizes invention.
