Description of reference numerals is as follows:
Second equipment, 105 first equipment 106
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Fig. 1 shows the circuit structure of an embodiment of automobile low-voltage power supply system energy saver described in the utility model.
Wherein, described automobile comprises ignition lock 102, and described ignition lock 102 generally comprises OFF, ACC, ON gear, and automobile is described low-voltage power supply system power supply by storage battery 101; Described low-voltage power supply system comprises first equipment 106 and normal second equipment 105 of powering of needs that does not need normal power supply, and any one described second equipment 105 directly links to each other with described storage battery 101 the two poles of the earth;
As seen from Figure 1, described automobile low-voltage power supply system energy saver can comprise:
When ignition lock 102 during at ACC or ON shelves, described second branch road is path, and the described armature 104 of described coil 103 absorption makes that described first branch road is path;
When ignition lock 102 during at the OFF shelves, described second branch road is for opening circuit, and described coil 103 discharges described armature 104 makes described first branch road for opening circuit.
In the above-described embodiments, when ignition lock 102 during at ACC or ON shelves, ignition lock 102 place branch roads are path.That is: when ignition lock 102 during at ACC or ON shelves, the junction circuit that the coil of ignition lock 102 and electromagnetic relay 107 is 103 (electromagnetic relay 107 input circuits) is path, and have electric current to pass through the coil 103 of electromagnetic relay 107 this moment; The armature 104 of the electromagnet absorption electromagnetic relay 107 that the iron core that coil 103 and coil 103 enclose is formed, make electromagnetic relay 107 open contact closures, this moment, storage battery 101 be path with the circuit (electromagnetic relay 107 output loops) of 106 of first equipment that does not need normal power supply, can power to first equipment 106 by storage battery 101.
This design makes when automobile key is in ACC or ON shelves that storage battery 101 is given does not need 106 power supplies of first equipment of normal power supply, and chaufeur can use some not need first equipment 106 of normal power supply when automobile does not start.Before automobile does not also start, when key pushes ACC or ON position, generally speaking, some do not need first equipment 106 of normal power supply, such as: radio receiver, Cigarette lighters etc. just can have been switched on, and first equipment 106 that does not need normal power supply that can switch on during this gear can also have electricity to transfer seat, sound system, windscreen wiper water-injection system, Cigarette lighter, seat heating, power moonroof and low pressure controller etc.The ignition lock 102 of order this moment is paths with the junction circuit (electromagnetic relay 107 input circuits) of the coil 103 of electromagnetic relay 107, and electromagnetic relay 107 output circuits that also determined to comprise first equipment 106 are paths.
In the above-described embodiments, when ignition lock 102 during at the OFF shelves, ignition lock 102 place branch roads are for opening circuit.That is: when ignition lock 102 during at the OFF shelves, the junction circuit that the coil of ignition lock 102 and electromagnetic relay 107 is 103 (electromagnetic relay 107 input circuits) there is no circuit this moment by coil 103 for opening circuit; Armature 104 is not subjected to the absorption of the electromagnet be made up of the iron core that coil 103 and coil 103 center on, then the open contact of electromagnetic relay 107 disconnects, this moment 106 of storage battery 101 and first equipment circuit (electromagnetic relay 107 output loops) for opening circuit, storage battery 101 is not powered to first equipment 106.
This design makes automobile key when the OFF shelves, and storage battery 101 does not give first equipment 106 power supplies, has reduced the feed situation after automobile key pulls out.When ignition lock 102 is in OFF, driving engine stop and bearing circle locked, have only this position just can take off key; Do not need the operation of first equipment 106 this moment, therefore the ignition lock 102 of order this moment is to open circuit with the junction circuit (electromagnetic relay 107 input circuits) of coil 103, and electromagnetic relay 107 output circuits that also determined to comprise first equipment 106 are to open circuit.
Above-mentioned design is divided into normal power supply with low-voltage power supply system and the two kinds of forms of seldom powering, and makes automobile can cancel the power supply to first equipment 106 that does not need normal power supply under some state, has saved the electric weight of storage battery 101, has played the effect of energy-saving and environmental protection.In above-mentioned design, any one described second equipment 105 directly links to each other with storage battery 101 the two poles of the earth, this makes the junction circuit of 105 of storage battery 101 and second equipment be path all the time, ignition lock 102 is no matter at ACC, ON shelves when still being the OFF shelves, and storage battery 101 all can give second equipment 105 power supplies.Wherein, second equipment shown in can be the equipment in whole-control system, battery management system, the charge system.Whether above-mentioned design makes automobile determine to give first equipment 106 of the not normal power supply of needs to power according to the gear of ignition lock 102, rather than under any circumstance all to 106 power supplies of first equipment; The serious feed situation of the storage battery 101 after having avoided the automobile stagnation of movement or having parked a period of time.In addition, can also control the disconnection of electromagnetic relay 107 and closed to reach the purpose of this utility model with controller.
According to the utility model, described automobile low-pressure energy-saving device can be installed on the new-energy automobile.
In another embodiment of the present utility model, all first equipment, 106 parallel connections are first to be connected in parallel, and described first is connected in parallel connects with described armature 104.
This design is independent of each other 106 of the equipment of winning, and opening and closing or the et out of order of first equipment on every parallel branch can not impact first equipment of other parallel branches.
Fig. 2 shows the principle of an embodiment of automobile low-voltage power supply system energy saver described in the utility model.As shown in Figure 2, on described first each parallel branch that is connected in parallel, can be in series with first fuse 201, on the circuit series of each second equipment 105, also can be in series with second fuse 202.In another embodiment of the present utility model, can be only at described first each parallel branch series connection first fuse 201 that is connected in parallel.Electric current on each fuse place branch road surpasses specified value after a period of time, and the heat that electric current produces makes the melt fusing of fuse, carries out short-circuit protection or serious overload protection thereby circuit is disconnected.
In an embodiment of the present utility model, when ignition lock 102 during at the OFF shelves, second equipment 105 enters the dormancy mode of operation.This design makes behind the engine off, needs second equipment 105 of normal power supply enter the very little state of a kind of power consumption, i.e. dormancy mode of operation; Under park mode, in case apply artificial operation (for example opening car door), park mode will be terminated.This design can greatly reduce the feed of storage battery 101.
In an embodiment of the present utility model, described storage battery 101 is lead-acid storage battery.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
