Description
Technical field
It the utility model is related to automotive check and security control association area, the auxiliary electricity of especially a kind of automotive lighting
Source system.
Background technology
Automobile has become one of main walking-replacing tool of today's society.With the development of science and technology, automotive engineering is also from having
Key develops into no key and starts flame-out control, when car owner stops working and leaves car, need to only press corresponding button i.e. achievable pair
The control of car.Especially automatically controlling for automobile lighting system also coordinates automotive engineering to obtain certain development.Also be exactly because
For these automatic technologies, car owner is alleviated to whether going out the concern of headlight etc., occur asking once automatically controlling operation
Topic, or fail to complete, all may be used because the interference of homogenous frequency signal does not have normal car locking to cause these to automatically control operation during car locking
It can bring certain vehicle or property loss.Also, the realization of these technologies still needs using Vehicular accumulator cell to not closing
The car light closed is powered, and consumes the energy of storage battery, have impact on the normal use of automobile.
Utility model content
The purpose of this utility model is to provide a kind of secondary power system of automotive lighting, it can overcome existing skill
The deficiency of art, is the secondary power system of automotive lighting a kind of simple in structure, easy to operate.
The technical solution of the utility model：A kind of secondary power system of automotive lighting, it is characterised in that it includes vapour
Car ignition switch amount detection module, auxiliary power module, power supply mode selection circuit module and control unit；Wherein, the vapour
Car ignition switch amount detection module detects the input terminal company of the shutdown signal of automobile ignition switch, its output terminal and control unit
Connect；The output terminal of described control unit is connected with power supply mode selection circuit module；The power supply mode selection circuit module point
It is not connected with auxiliary power module and car in secondary battery unit；The output terminal connection lighting system of the auxiliary power module.
The auxiliary power module is by photovoltaic cell, Buck converters, lithium battery charging circuit, lithium battery and Boost liters
Buckling parallel operation is in be connected in series composition successively.
The photovoltaic cell is that the solar panel no less than 1 piece is formed；The solar panel is installed on automobile
Top, the lithium battery is as energy-storage units.
Described control unit can be that automobile master controller can also be the controller unit being separately configured.
Described control unit is that microcontroller is STM32F103 singlechip chips.
The power supply mode selection circuit module is high-power switch device, and the control signal sent by control unit is selected
The conducting of power supply all the way is selected, is powered for automobile lighting system.
The operation principle of the utility model：The closing letter of automobile ignition switch amount detection module detection automobile ignition switch
Number, when definite automobile has stopped working or after car locking, on-off model is sent to control unit, supplier of electricity is controlled by control unit
Formula selection circuit module turns on the circuit of auxiliary power module, simultaneously closes off Vehicular accumulator cell current supply circuit；The photograph of automobile at this time
Bright system is by auxiliary power module loop power supply.If the function of occurring being automatically closed car light at this time loses or car owner leaves car
Forget closing vehicle lamp, car light can carry out operation of turning off the light under auxiliary power module power supply, even operation of turning off the light is not carried out,
The electric energy of Vehicular accumulator cell will not be therefore consumed, causes the generation for not having electrical phenomena, and then ensure that the normal use of vehicle.
The superiority of the utility model：It is simple in structure, can be according to the car locking information auto switching electric source of automobile；Solar energy
The combination of battery and lithium battery alleviates the burden using Vehicular accumulator cell, extends the service life of storage battery.
