A kind of vehicle hazard hazard warning flasher circuit
Technical field
The invention belongs to automobile technical field, it is related to a kind of vehicle hazard hazard warning flasher circuit, it is particularly a kind of in danger
Dangerous hazard warning flasher remains to realize the vehicle hazard hazard warning flasher circuit of steering indicating light work after opening.
Background technology
Hazard warning lamp in automobile, is commonly called as double flashing lights or double jump lamp, and double flashing lights show that vehicle there occurs after opening
Special circumstances, remind other vehicles and pedestrian to note or avoid.
Existing hazard warning lamp is after unlatching, and steering indicating light can not be used, and needs manual-lock to endanger in steering or simultaneously road
Dangerous hazard warning flasher, is then turned on also needing to be then turned on hazard warning lamp behind steering indicating light, Guo Wanhuobing roads.It is cumbersome, and
Most of drivers are unwilling so to operate, and the car driving intention can not be then distinguished for other vehicles or pedestrians, peace is easily produced
Full accident.
For above-mentioned problem, existing Chinese patent open source literature discloses a kind of automobile signal light and turned to preferentially
Controller [application number:CN201320291802.3], including signal light control input module, flashing relay and the electricity that automatically switches
Road.Wherein, signal light control input module, including turn to input control circuit and double sudden strain of a muscle control circuits;Flashing relay and light
Control input module is connected, to receive light controling signal;Automatic switch-over circuit is connected to steering input control circuit and double sudden strains of a muscle
Control between the output of circuit and the input of flashing relay, to turn to when input control circuit sends light controling signal certainly
The double connections for dodging control circuits and flashing relay of cut-out are moved, and when steering input control circuit does not send light controling signal
The double connections for dodging control circuit and flashing relay of turn on automatically.Although the invention is realized by increasing by an automatic switch-over circuit
Automobile signal light turns to preferential purpose, but invention circuit connection is complicated, it is necessary to coordinate light input module, turn to input
Circuit is controlled, also flashing relay could be realized, and need to be controlled by control device, and cost is higher.
The content of the invention
The purpose of the present invention is there is above mentioned problem for existing technology, it is proposed that a kind of vehicle hazard hazard warning flasher
Circuit, the vehicle hazard hazard warning flasher circuit technical problem to be solved is:How after hazard warning lamp unlatching
Remain to realize the unlatching of steering indicating light.
