Description

The Der Scheinwerfer mit FernlichtAbblendlichtStandlicht device that brightens

The utility model relates to the Der Scheinwerfer mit FernlichtAbblendlichtStandlicht device that brightens.

In order to adapt to night running, the lighting system all is housed on the automobile, and stipulated the Der Scheinwerfer mit FernlichtAbblendlichtStandlicht lighting criteria with the form of law, night light must guarantee car preceding more than 100 meters the road surface have evenly and bright illumination, make chaufeur can distinguish car preceding 100 meters with interior road surface situation, to guarantee the safety traffic of night travel.In order to guarantee that Der Scheinwerfer mit FernlichtAbblendlichtStandlicht has stronger illumination, the power of headlight generally is about 60～80W, 2 or 4 headlights are arranged, adopt 12V power supply on the car: according to power formula: P=IU, I, U are electric current, the voltage of circuit in the formula, can learn that by formula the electric current that flows through big lamp driver is 16～18 amperes, the working current of headlight is very strong, will produce many problems in actual use.Owing to have only a total wire fuse in original Lighting System, so as long as when having a branch road circuit to be short-circuited, other headlight also extinguishes Zong wire fuse will fuse, and brings very big danger to night travel thereupon; Because the headlight line current is very strong, total insurance will often go wrong influences driving, if total fuse melting but can not find suitable wire fuse, at will look for a copper wire to replace, and can make total insurance ineffective like this, causes full fare bundle to catch fire easily; As frequent replacing wire fuse, make the connection terminal generation at wire fuse two ends loosening, cause terminal and wire fuse bad contact, the fault that makes headlight system when night light, occur cutting in and out; Electric current is crossed by force also can make the headlight aging circuit, causes the circuit internal resistance excessive, can make the obvious deepening of illumination intensity of headlight system, makes the requirement of headlight system illumination intensity out of reach technical standard.Because the headlight line electricity flows through by force, the Der StandlichtScheinwerfer und Parkleuchtenschalter and the contact on the beam deflector switch of control headlight system are often burnt out, increased the fault rate of automotive wire bundle like this, also increased simultaneously the service expenditure of automobile, line failure rate increases, influence the illumination of night travel, cause many vehicles to travel in spite of illness, the safety of vehicle and reliability are greatly reduced.Simultaneously, the contact of Der StandlichtScheinwerfer und Parkleuchtenschalter and beam deflector switch because the working current of headlight system is directly flowed through causes big lamp driver internal resistance to increase after these contacts are burnt out, and can make the requirement of headlight system brightness deepening out of reach technical standard.In addition, some automobile headlight system adopts single wire system.Utilize car body to make ground wire, " ground connection place " can get rusty on car after the long-term use, causes bad contact, also can make the requirement of headlight system deepening illumination intensity out of reach technical standard.

The purpose of this utility model is to avoid the problem that occurs in the above-mentioned present technology, and provides the Der Scheinwerfer mit FernlichtAbblendlichtStandlicht of a kind of " insuring relay system along separate routes " device that brightens, safe and reliable raising used life.

The purpose of this utility model can reach by the following technical programs: two relays in parallel on the country beam contact of beam deflector switch control in the automobile circuit system, and vehicle head both sides country beam is connected in parallel on one of them relay; Two country beams in vehicle head middle part are connected in parallel on another relay, respectively go here and there a wire fuse simultaneously on each country beam circuit.Contact at beam deflector switch control dipped beam also connects a relay, and vehicle head both sides passing light is connected in parallel on this relay, and also is connected to wire fuse on this circuit parallel.Silicon rectification generator joins on the moving contact of three relays and the car, makes the power supply of headstock instant and near light lamp, and the negative pole of storage battery joins on the negative pole of instant and near light lamp and the car simultaneously.By such scheme as can be known, the utility model is the mode that has adopted " the single lamp control of five tunnel cede insurances ", has reduced the electric current that flows through each cede insurance, even one the tunnel short circuit occurs, does not influence whole Lighting System, thereby can realize this purpose.

The utility model is compared with present technology can have following effect: owing to adopted " the single lamp control of five tunnel cede insurances ", promptly four country beams are respectively established an insurance, and circuit is independent; The power of two passing lights is smaller relatively, a shared insurance; If short circuit occurs on a certain circuit, and can not influence whole Lighting System, guarantee the safety of night travel; The electric current of each cede insurance of flowing through has simultaneously reduced 3～4 times with respect to the electric current of the former total insurance of flowing through, thereby conservative factor improves 3～4 times.Three relays have been realized headlight system with the big electric current of little current control, and are very little through the electric current of switch (4,5) contact, can prolong the used life of two switches (4,5).

To be further described the utility model below in conjunction with accompanying drawing:

By shown in Figure 1, have on the automobile to connect starter relay 2 and amperemeter/ammtr 3, Der StandlichtScheinwerfer und Parkleuchtenschalter 4 and beam deflector switch 5 on the power supply (storage battery) 1, also have instant and near light lamp (15～17) on the headstock and be power supply 1 electrically-charged silicon rectification generator 6.The utility model is two relays (7,8) in parallel on the contact of beam deflector switch 5 control country beams, and the preceding both sides of headstock country beam 15 is connected in parallel on the relay 7; Two country beams 16 of headstock front middle part are connected in parallel on the relay 8, and (11～14) are protected in series connection on each country beam circuit simultaneously; Succeed electrical equipment 9 on the contact of beam deflector switch 5 control passing lights, the preceding both sides of headstock passing light 17 is connected in parallel on the relay 9 and series connection wire fuse 10 on the passing light circuit.By three relays, can the change light of bearing very big electric current in the circuit open the light 5 and Der StandlichtScheinwerfer und Parkleuchtenschalter 4 change the control element of control relay into, very little through the electric current of their contacts, can prolong the used life of contact; " five tunnel insure along separate routes " one road goes wrong and do not influence the overall situation.The connection terminal B of silicon rectification generator 6 joins as the power supply of instant and near light lamp (15～17) through the moving contact of lead 19 and three relays, makes headlight system have one directly and the failure-free power supply.The negative pole of above-mentioned instant and near light lamp (15～17) joins through the negative pole of lead 18 with power supply 1, to guarantee the instant and near light lamp system good ground connection is arranged.
