The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, preferred embodiment cited below particularly also cooperates appended graphic elaborating.
Now cooperate graphic explanation preferred embodiment of the present utility model.
See also Fig. 1, the headlight for vehicle automatic control device 100 of present embodiment can be applicable among general automobile or the locomotive, and it mainly includes a power supply 110, one first head lamp 121, one second head lamp 122, a source switch 130, a switching switch 140, one first relay 150, one second relay 160 and a control unit 170.
Among present embodiment, first head lamp 121 can be a dipped beam head lamp, and second head lamp 122 can be a far-reaching headlamp.
Change-over switch 140 has one the 3rd end points 143, one the 4th end points 144 and a five terminal point 145.The 3rd end points 143 is connected in second end points 132 of source switch 130, and the 3rd end points 143 selectivity are connected in the 4th end points 144 or five terminal point 145.At this, change-over switch 140 is the running that is used for switching first head lamp 121 or second head lamp 122.
Next the function mode of headlight for vehicle automatic control device 100 is described.
At first, be activated back (for example, an operator or a driver with key operated source switch 130 backs) at source switch 130, its first end points 131 can be communicated in second end points 132.Simultaneously, the operator can utilize change-over switch 140 to select to make first head lamp 121 or second head lamp 122 to operate.For instance, as shown in Figure 1, when the 3rd end points 143 of change-over switch 140 was communicated in its 4th end points 144, on behalf of the operator, this select first head lamp 121 is operated.
Then, control unit 170 can come interpretation whether to open first head lamp 121 according to received engine speed signal or accelerator open degree signal.More detailed, when control unit 170 received engine speed signals (or accelerator open degree signal) were lower than a default engine speed value (or a default accelerator open degree value), this promptly represents an engine (not shown) was the state that is in the state that does not start or is in tickover.At this moment, the inside of control unit 170 can be in open circuited state, thereby makes and can't form a loop between first field winding 151 of power supply 110, source switch 130, change-over switch 140, first relay 150 and the control unit 170.In other words, electric current can be from flow through first field winding 151 of first relay 150 of the positive pole of power supply 110.Therefore, first field winding 151 can be by not excitatory, thereby make the first excitatory switch 152 of the relay 150 of winning still keep open circuited state.As mentioned above, first head lamp 121 can't be unlocked or operate.On the other hand, when control unit 170 received accelerator open degree signals (or accelerator open degree signal) were higher than this default engine speed value (maybe should preset the accelerator open degree value), this promptly represents engine was to be in normal operation.At this moment, the inside of control unit 170 can be in the state of conducting, thereby can make and form a loop between first field winding 151 of power supply 110, source switch 130, change-over switch 140, first relay 150 and the control unit 170.In other words, electric current can be from flow through first field winding 151 of first relay 150 of the positive pole of power supply 110.At this, first excitatory switch 152 meetings of first relay 150 are closure by the excitatory operation of first field winding 151, thereby makes the first excitatory switch 152 of power supply 110, first relay 150 and first head lamp 121 form a loop.Therefore, electric current can be from the positive pole of power supply 110 the flow through first excitatory switch 152 and first head lamp 121 of first relay 150.As mentioned above, first head lamp 121 can be unlocked or operate.
Similarly, when the 3rd end points 143 of change-over switch 140 is communicated in five terminal when putting 145, on behalf of the operator, this select second head lamp 122 is operated.At this, because the mode of control second head lamp 122 runnings is identical with the mode of above-mentioned control first head lamp 121 runnings, so omit its repeat specification at this.
As mentioned above, among headlight for vehicle automatic control device 100, because the unlatching or the running of first head lamp 121 or second head lamp 122 are to be carried out according to engine speed value (or accelerator open degree value), so the power consumption that can effectively save power supply 110, and then the stability also can effectively promote engine running the time.
