Chinese patent Granted publication number: CN201863761U, Granted publication day: on 06 15th, 2011, a kind of device of automatically shutting down automobile big lamp is disclosed, this device comprises combined switch, photosensor, vehicle-mounted computer and relay, combined switch is connected input end and is connected with the mouth of automobile power source with ignition lock, combined switch, the input end of the output termination vehicle-mounted computer of ignition lock and photosensor, the input end of the output relay termination of vehicle-mounted computer, the output termination Der Scheinwerfer mit FernlichtAbblendlichtStandlicht of relay, when daytime driving person does not close headlight when just leaving automobile, automobile can cut out headlight automatically.But this device is the Shortcomings part also, the photosensor of this device is only when detecting that bright intensity is lower than preset value on every side, Der Scheinwerfer mit FernlichtAbblendlichtStandlicht just can be closed, and in some time period, when chaufeur leaves automobile and forgets and close headlight, and bright intensity at this moment is greater than preset value and do not change for a long time, and at this moment the storage battery of automobile will be powered for Der Scheinwerfer mit FernlichtAbblendlichtStandlicht always, cause the storage battery power consumption serious, even the negative electricity situation occurs so that can't provide power supply for next automobile starting.
The utility model content
The utility model is in order to overcome the deficiencies in the prior art, a kind of automatically shutting down automobile big lamp device is provided, no matter by day or evening, when chaufeur does not have the closing automobile headlight just to leave automobile, automobile can cut out headlight automatically, avoid head light that the power consumption of automotive battery is complete, cause automobile to start.
To achieve these goals, the utility model is by the following technical solutions:
A kind of automatically shutting down automobile big lamp device, comprise BCM, Der Scheinwerfer mit FernlichtAbblendlichtStandlicht, and be connected to Der StandlichtScheinwerfer und Parkleuchtenschalter and relay between power supply and the Der Scheinwerfer mit FernlichtAbblendlichtStandlicht, described automatically shutting down automobile big lamp device also comprises car door locking detecting device, human body detection sensor, the ignition lock detecting device, the Der StandlichtScheinwerfer und Parkleuchtenschalter signal supervisory instrument, described car door locking detecting device, human body detection sensor, the ignition lock detecting device, the mouth of Der StandlichtScheinwerfer und Parkleuchtenschalter signal supervisory instrument is connected with the input end of BCM respectively, the mouth of described BCM is connected with relay, human body detection sensor and BCM interconnection.Whether car door locking detecting device closes for detection of car door, whether the ignition lock detecting device is extracted for detection of key, the Der StandlichtScheinwerfer und Parkleuchtenschalter signal supervisory instrument is enough to close for detection of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht, human body detection sensor is for detection of whether the people is arranged in the car, while car door locking detecting device, the ignition lock detecting device, the Der StandlichtScheinwerfer und Parkleuchtenschalter signal supervisory instrument, the result that human body detection sensor will detect sends to BCM with signal form, if unmanned in the car, closing of the door, key is extracted and headlight does not cut out, then BCM can send instruction to relay, the relay cut off, Der Scheinwerfer mit FernlichtAbblendlichtStandlicht is closed.
As preferably, diode of the two ends reverse parallel connection of relay.Relay two ends and the diode that connects shield; when relay disconnects; can produce a counter potential; this counter potential even a power line voltage exceed several times to tens times; this counter potential can cause the damage of other electrical equipment original papers; diode of reverse parallel connection then can absorb this counter potential, the protective circuit normal operation.
As preferably, human body detection sensor is weight sensor, be located at automotive seat below.Whether weight sensor for detection of there being the people in the car, and the information that detects is sent to BCM.
As preferably, human body detection sensor is infradred sensor, is located at the top in the auto body.Whether infradred sensor for detection of there being the people in the car, and the information that detects is sent to BCM.
Compared with prior art, the utlity model has following beneficial effect: easy to use, simple to operate, good reliability, in car unmanned and closing of the door, when key is extracted, if Der Scheinwerfer mit FernlichtAbblendlichtStandlicht is being opened, automobile energy autoshutdown headlight avoids storage battery negative electricity so that automobile to start.
