Accompanying drawing explanation
Next will be described in further detail specific embodiment of the utility model by reference to the accompanying drawings, wherein:
Fig. 1 is the structural representation of the car body controller of prior art;
Fig. 2 is the circuit diagram of the automotive battery anti-theft system of prior art;
Fig. 3 is the circuit diagram of the automotive battery anti-theft system of first embodiment of the present utility model;
Fig. 4 is the circuit diagram of the automotive battery anti-theft system of second embodiment of the present utility model.
Detailed description of the invention
With reference to figure 3, the automotive battery anti-theft system in the present embodiment comprises storage battery, standby battery, car body controller and as the loudspeaker B0 of annunciator and lamp L0, and wherein, loudspeaker B0 is independently alarming horn, and lamp L0 is independently alarm lamp.Storage battery is connected with the first feeder ear P1 of car body controller (BCM), and standby battery is connected with the second feeder ear P2 of BCM, and the first warning mouth P3 of loudspeaker B0 and BCM connects, and the second warning mouth P4 of lamp L0 and BCM connects.Remote-control key and car body controller communicate to connect, after BCM receives the block signal of remote-control key C, car load is in armed state, standby battery starts to work, when burglar wants to take storage battery, after the circuit disconnection of B+ B1 or negative pole B2, first feeder ear P1 dead electricity becomes low level, now standby battery keeps powering to BCM, first warning mouth P3 exports high level, loudspeaker B0 pipes, or the second warning mouth P4 exports high level, lamp L0 glimmers, or the first warning mouth P3 and the second warning mouth P4 exports high level simultaneously, ring loudspeaker light flash simultaneously.If connect storage battery B1 or B2 pin during reporting to the police immediately, then recover the power supply to the first feeder ear P1, then releasing after 3 circulations of reporting to the police, if now again fall dismounting, then 3 circulations of again reporting to the police are until standby battery power shortage.Usual standby battery can provide 20 above driving electric energy that circulate.When normal replacing storage battery, unlocking signal can be sent by remote-control key C to BCM and remove car load armed state.Storage battery and standby battery connect with wire between A point and B point, namely be connected with wire between B+ with standby battery positive pole, and wire is in series with diode D1, therefore storage battery can charge for standby battery, the effect of the diode D1 between A point and B point prevents between storage battery turnoff time standby battery to the P1 end power supply of BCM, and therefore the existence of diode D1 can make storage battery for standby battery provides unidirectional charging and can not affect anti-theft effect.Adopt the benefit of independently loudspeaker B0 and lamp L0 to be easy for installation, avoid BCM wrong line, certainly as shown in Figure 1, BCM still will connect car light, horn trumpet, Door Lock etc.Standby battery is arranged in operator's compartment, more hidden and be not easy stolen.
With reference to figure 4, with first embodiment unlike, in the second embodiment, adopt the left steering lamp L1 of automobile and right steering lamp L2 as alarm lamp, adopt horn trumpet B1 as alarming horn, without the need to other optional feature, cost is lower.Wherein, left steering lamp connects the second warning mouth P4 of BCM, and right steering lamp L2 connects the 3rd warning mouth P5 of BCM, directly drives power supply, can meet warning function by BCM, again can the car light diagnosis function that requires of satisfy regulatory.With first embodiment also exist unlike, the first warning mouth P3 is not directly connected with horn trumpet B1, and horn trumpet B1 is powered by standby battery.In the present embodiment, have employed a horn relay R1, horn trumpet is connected with a pair open contact of horn relay R1, coil one end of horn relay R1 connects standby battery, the other end is divided into two branch roads, one of them branch road connects the first warning mouth P3 of BCM, and another branch road connects horn hood K switch 1.Like this, when the first energization input P3 power-off, first warning mouth P3 output low level, conducting between emergency battery positive pole and the first energization input P3, horn relay R1 coil obtains electric adhesive, open contact is closed makes horn trumpet B1 pipe, and the second warning mouth P4 and the 3rd warning mouth P5 exports high level makes left steering lamp L1 and right steering lamp L2 glimmer.And chaufeur needs ring loudspeaker prompting road pedestrian when noting, pressing horn hood K switch 1 can make horn relay R1 coil obtain electric, and horn trumpet B1 pipes.
From above two embodiments, the utility model adopts car body controller (BCM) to replace original antitheft relay, and rely on the decision circuit of BCM itself to realize the first feeder ear P1 to disconnect, both when the stolen dead electricity of storage battery, the closed warning of alarm circuit.Visible by comparison diagram 2, Fig. 3 and Fig. 4, system in Fig. 3 and Fig. 4 is from outside line, the circuit of drawing from storage battery does not increase, also expose without extra relay, therefore good concealment, burglar can not find that storage battery adds anti-theft feature, also whole warning cannot be made malfunctioning by the mode of short circuit.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present utility model and scope.
