Abstract
The utility model discloses a kind of headlight for electric vehicle control circuit, it is characterized in that: described control circuit comprises alarm, described alarm is powered by electric vehicle power sources, and inside has relay, and described relay contact two ends are connecting headlamp power supply and headlight respectively; Described alarm is connected with photo resistance, according to the signal of photo resistance, exports control signal control relay break-make.The utility model utilizes the additional photo resistance of the relay of alarm automatically open to realize headlight and close, and when extraneous light is not enough, headlight lights automatically, and time bright and clear, headlight cuts out automatically, danger of being born after avoiding user to drive a vehicle evening not opening headlight.Realized the delay-action of headlight by single-chip microcomputer, headlight can also Delayed illumination after powered-down to make user simultaneously.
Description
Technical field
The utility model belongs to vehicle technology field, particularly relates to a kind of headlight for electric vehicle control circuit with light control functionality.
Background technology
Existing electric motor car is headlight also power-off extinguishing thereupon after power cut-off, in the environment of dark, cannot provide exterior lighting for car owner.Electric motor car in the process of moving in addition, and when outside insufficient light, headlight cannot light automatically, on the one hand cannot illuminate road surface, can not allow other vehicle Timeliness coverage bicyclist on the other hand, there is potential safety hazard.
Summary of the invention
The utility model object be for the defect of prior art provide a kind of can bright light and the time delay headlight for electric vehicle control circuit of turning off the light automatically.
The utility model for achieving the above object, adopts following technical scheme:
A kind of headlight for electric vehicle control circuit, it is characterized in that: described control circuit comprises alarm, described alarm is powered by electric vehicle power sources, and inside has relay, and described relay contact two ends are connecting headlamp power supply and headlight respectively; Described alarm is connected with photo resistance, according to the signal of photo resistance, exports control signal control relay break-make.
It is further characterized in that: described alarm inside has the first relay, the second relay and single-chip microcomputer; Described first relay connects electric vehicle power sources, by Single-chip Controlling break-make; Described first relay exports as the input of the second relay after electric pressure converter, and described second relay, by Single-chip Controlling break-make, exports connecting headlamp; Described single-chip microcomputer connects described photo resistance, according to the break-make of photo resistance signal controlling second relay; Described single-chip microcomputer work triggering signal is electric motor car key switch KEY.
Described electric pressure converter is 12V electric pressure converter.
The second relay control signal that described single-chip microcomputer exports is delay control signal.
Further: described electric vehicle power sources is 48V.
The utility model utilizes the additional photo resistance of the relay of alarm automatically open to realize headlight and close, and when extraneous light is not enough, headlight lights automatically, and time bright and clear, headlight cuts out automatically, danger of being born after avoiding user to drive a vehicle evening not opening headlight.Realized the delay-action of headlight by single-chip microcomputer, headlight can also Delayed illumination after powered-down to make user simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model circuit theory schematic diagram.
Embodiment
A headlight for electric vehicle control circuit as shown in Figure 1, described control circuit comprises alarm, and described alarm is powered by 48V electric vehicle power sources, and inside has the first relay, the second relay and single-chip microcomputer; Described first relay connects electric vehicle power sources, by Single-chip Controlling break-make; Described first relay exports as the input of the second relay after 12V electric pressure converter, and described second relay, by Single-chip Controlling break-make, exports connecting headlamp; Described single-chip microcomputer connects described photo resistance, according to the break-make of photo resistance signal controlling second relay; Described single-chip microcomputer work triggering signal is electric motor car key switch KEY.The second relay control signal that described single-chip microcomputer exports is delay control signal.
After key switch KEY closes, alarm electric door lock holding wire detects KEY turn-off transient, alarm inner microprocessor detect photo resistance resistance, if detect and be in insufficient light state, the inner first relay moment adhesive of alarm makes alarm electric door lock holding wire be in high level state, now voltage exports 12V voltage to alarm by 12V electric pressure converter, after the microprocessor detect of alarm has 12V to input, single-chip microcomputer makes the second relay adhesive by instruction, export 12V voltage to headlight, make headlight Chang Liang (time is set by single-chip microcomputer).When the photo resistance being placed in electric vehicle instrument place detects bright and clear, alarm single-chip microcomputer does not work, and headlight can not be bright, reaches the object of power saving.
When key switch KEY is in opening, now electric motor car 12V electric pressure converter has 12V to export always, and the alarm single-chip microcomputer moment monitors photosensitive resistance, if when detecting insufficient light, alarm makes the second relay 2 adhesive by single-chip microcomputer, and now headlight is in normal bright state.Have electricity because key switch KEY is in unlatching, the first relay does not need work always, does not carry out time setting after microprocessor detect to headlight Chang Liang, and the adhesive of an instruction second relay, headlight is Chang Liang always.When the photo resistance being placed in electric vehicle instrument place detects bright and clear, alarm single-chip microcomputer does not work, so headlight can not be bright, reaches the object of power saving.
