Description

General Motors driving lamp performance indicator

General Motors driving lamp performance indicator belongs to the car electrics technical field, is a kind of existing indicator lamp on the automobile instrument panel that directly utilizes, and accurately indicates the indicating device of running light performance.

There are very big defective in the driving lamp control and the indicating circuit that use at present.Subject matter is the actual state that the gauge panel indicator lamp can not reflect vehicle light fully.For example, if the bulb that turns to of vehicle or suddenly damages because of long-term use, chaufeur is opened pole changer under steam, and turning indicator is bright on gauge panel, does not have indicating fault.So chaufeur can't know that steering indicating light damages, and brings very big hidden danger to traffic safety.In addition stoplight stop lamp, night travel lamp, the backing-up lamp identical with turning to problem.Promptly stepped on brake pedal, but because brake light bulb or BK Brake Switch are damaged, and stoplight stop lamp does not work at all, this is a danger close for the nearer front vehicle of follow-up.Above-described various hidden danger mainly is because the design shortcoming of light circuit causes.Left steering circuit with peony brand MD6601C type passenger vehicle is an example, because left turn indicator lamp all is connected in parallel on (Fig. 1) in the same circuit on left front, left back and the gauge panel.When opening car light,, can on gauge panel, there be fault to show if any driving lamp of front and back is damaged.On the contrary, chaufeur also can normally be indicated.

The purpose of General Motors driving lamp performance indicator is in order to address the above problem, a kind of General Motors driving lamp performance indicator of simple and easy to do practicality to be provided.

The principle of design of General Motors driving lamp performance indicator is can produce magnetic field and magnetic according to electrical conductor to be subjected to the magnetic field effect and to be subjected to displacement this two physical propertys, with the two in conjunction with reaching design goal.The purpose of General Motors driving lamp performance indicator is achieved in that two coil L1 of serial connection and L2 in one road D1 car light circuit of driving lamp optical circuit, two coil L3 of serial connection and L4 in the D2 car light circuit of another road; Coil L1 and L3 are wrapped in open type dry-reed tube K1 and K3 goes up two electromagnetic switchs 1 of composition and 3, and coil L2 and L4 are wrapped in normally closed dry reed pipe K2 and K4 goes up two electromagnetic switchs 2 of composition and 4; Electromagnetic switch 1 and 3 is cascaded and forms logical AND and concern controller dial plate indicator lamp D3, and electromagnetic switch 2 and 4 is connected in parallel and forms the logical OR relation and control buzzer phone F.When bulb D1 and D2 are intact, flow through coil with regard to having very big electric current, produce enough strong magnetic field, make be magnetized the immediately adhesive or separately of the two poles of the earth of dry-reed tube.At this moment, dry-reed tube K1 and K3 adhesive, the luminous work of the indicator lamp on the gauge panel; Dry-reed tube K2 and K4 branch are opened, and buzzer phone F does not ring.When bulb D1 or D2 damage, there is not electric current to flow through coil, dry-reed tube K1 or not adhesive of K3, the indicator lamp D3 on the gauge panel is not luminous; Dry-reed tube K2 or K4 do not open, and buzzer phone F rings.So have only under the failure-free situation of light circuit, the indicator lamp on the gauge panel just has indication, otherwise not indication of indicator lamp, buzzer phone F audible alarm.This has realized purpose by driving lamp signal control gauge panel indicator lamp a tree name.

General Motors driving lamp performance indicator has adopted novel circuit layout, generation with wigwag control indicator lamp signal, do not have the indicator lamp signal without wigwag, fundamentally solved the indicator lamp signal on the gauge panel that driving lamp circuit that existing vehicle uses causes and the conflicting problem of actual state of driving lamp.The various signals that it reflected are reliable as true as a die.No matter in stopping or travelling, full chaufeur can both be found the problem of light aspect, any position of car from the gauge panel whenever and wherever possible, in time handle, make the light performance of vehicle be in the good technical state all the time, guaranteed traffic safety.General Motors driving lamp performance indicator has been arranged, and chaufeur does not need to want others to cooperate as before or get on or off the bus back and forth, judges easily by the indicator signal on the gauge panel whether car light has problem fully.In circuit layout, utilized low, big these characteristics of electric current of voltage in the car bulb circuit, very little coil of series connection just can produce enough strong magnetic field in circuit.Because the number of turn of coil L seldom, do not influence the brightness of driving lamp in circuit.Select for use dry-reed tube K and coil L form electromagnetic switch be because dry-reed tube K have volume little, be active in one's movements reliable, price is low, simultaneously because dry-reed tube K is a glass-encapsulated, can make the switch contact oxidation in the air and influence reliability because of being exposed to.Therefore whole electromagnetic switch does not need maintenance.
