Description
Technical field
The utility model relates to a kind of for motor vehicle electric power system, particularly improves for motor vehicle electric power system that the electric generator of vehicle electric energy uses about one.
Background technology
The collocation method of general locomotive circuit is for exchanging or two kinds of direct currents.Generator is through the electric energy that vehicle operation produces, be divided into being sent to after the direct rectification transferring to the vehicle circuit after the battery storage and using, or with power distribution for exchange use and DC charging two parts respectively supply vehicle different piece circuit use two kinds.The AC power that wherein distributes only when vehicle operation, is just powered when meaning is generator for electricity generation.
Fig. 1 is the calcspar that a habit has the electric power system of vehicle.Alternating current generator 10 outputs one first AC power AC1 give full-wave rectifier 11.Full-wave rectifier 11 is one first DC power supply DC1 with the first AC power AC1 rectifying and wave-filtering.Battery 12 is connected to full-wave rectifier 11 and receives the first DC power supply DC1.When vehicle operation, alternating current generator 10 activates sends the first AC power AC1, sees through full-wave rectifier 11 thereupon and produces the first DC power supply DC1.Battery 12 receives the charging of the first DC power supply DC1 electric energy.The power supply of all circuit on battery 12 supply vehicles.
First lighting lamp group 15 is the basic light fixture of vehicle use at night, for example instrument board light fixture.Second lighting lamp group 14 is vehicle advance night the light fixture group that illumination uses, for example near/far-reaching headlamp.Switch 13 is the multisection type switch.When switch 13 was first section, terminal A and terminal B in the switch 13 were joined, and the first DC power supply DC1 is connected to first lighting lamp group 15 and first lighting lamp group 15 is lighted.When switch 13 was second section, terminal A in the switch 13 and end points C joined, and the first DC power supply DC1 is connected to first lighting lamp group 15 and second lighting lamp group 14 and first lighting lamp group 15 and second lighting lamp group 14 are lighted simultaneously.
The whole power supplys of vehicle are by battery supplied, and its advantage is that circuit can obtain stable power supply, even not running of generator also can be taken the electric energy in the battery at any time.Its shortcoming is in the car type at little air displacement (CC number), because of the restriction of vehicle structure itself, can't provide the storage battery of powerful generator and high power capacity, so the battery of vehicle is easy to regard to the electric weight deficiency.
Fig. 2 has the calcspar of the electric power system of vehicle for another habit.Alternating current generator 20 outputs one first AC power AC1 give half-wave voltage regulator 21.Half-wave voltage regulator 21 is divided into first with the first AC power AC1 and involves half-wave two parts down.Last half-wave part is output as one first DC power supply DC1 behind rectifying and wave-filtering.Following half-wave partly is output as one second AC power AC2.Battery 22 is connected to half-wave voltage regulator 21 and receives the first DC power supply DC1.When vehicle operation, alternating current generator 20 activates sends the first AC power AC1, sees through half-wave voltage regulator 21 thereupon and produces the first DC power supply DC1 and the second AC power AC2.Battery 22 receives the charging of the first DC power supply DC1 electric energy.The power supply of all circuit outside the night lighting device on battery 22 supply vehicles.
First lighting lamp group 25 is the basic light fixture of vehicle use at night, for example instrument board light fixture.Second lighting lamp group 24 is vehicle advance night the light fixture group that illumination uses, for example near/far-reaching headlamp.Switch 23 is the multisection type switch.When switch 23 was first section, terminal A and terminal B in the switch 23 were joined, and the second AC power AC2 is connected to first lighting lamp group 25 and first lighting lamp group 25 is lighted.When switch 23 was second section, terminal A in the switch 23 and end points C joined, and the second AC power AC2 is connected to first lighting lamp group 25 and second lighting lamp group 24 and first lighting lamp group 25 and second lighting lamp group 24 are lighted simultaneously.
The electric energy of generator is told interchange partly supply with lighting device, following several shortcomings are arranged: the electric energy of battery charge reduces, and charge rate is slack-off; Use generator directly to export and be converted to AC power, when the vehicle gait of march was slow, the brightness of car light will weaken, and may influence traffic safety.
The utility model content
The purpose of this utility model provides a kind of for motor vehicle electric power system.
The purpose of this utility model is achieved in that for motor vehicle electric power system separates first lighting lamp group and second lighting lamp group that the ground electrical power distribution is given vehicle, and comprising: an alternating current generator provides first AC power; One rechargeable battery; One rectification distributor comprises: first dispense path couples first AC power to export first DC power supply so that rechargeable battery is charged; One second dispense path is coupled to first alternating voltage and receives first AC power to export second AC power; One multisection type control device when multisection type control device during in first fragment position, is connected to first lighting lamp group with second AC power; And, second AC power is connected to first lighting lamp group, and rechargeable battery is connected to second lighting lamp group when multisection type control device during in second fragment position.
The device that uses the utility model to provide is given up no electric energy in the time of can be with rectification and is made full use of, and except night during instrumentation plate light fixture, and this part can't Xiao Mao electric energy and the generator electric energy fully can be applied to charging.And utilizing the circuit of this part electric energy independent by the Circuits System of vehicle, remaining circuit uses the Zheng Ti Xiao Mao electric energy speed of battery power to descend, and the battery power up time is prolonged.
