The specific embodiment
Following bonded circuitry block scheme and schematic circuit diagram specify the utility model and how to realize:
As Fig. 1-Fig. 3, the utility model multi-purpose vehicle(MPV) starts power supply and comprises that charge circuit 1, storage battery B1, anti-battery folder reversal connection/short-circuit protection circuit 2, flash lamp circuit 3, electric weight detection/display circuit 4, inverter circuit 5, fluorescent tube circuit 6, shot-light L1 and air pump M1 form; Adopt anti-battery folder reversal connection/short-circuit protection circuit high-current relay JD1 and polarity detect the break-make between control circuit control product internal battery and the automotive battery; Under the normal condition, relay J D1 is in off-state, and battery folder 7 is not charged; When battery folder 7 was clipped on the automotive battery, polarity detected the polarity that control circuit detects automotive battery automatically, if polarity is correct, then control relay JD1 conducting is connected product internal battery B1 and automotive battery; If polarity connects and inverse time keeps off-state.One of them contact of high-current relay JD1 connects internal battery B1 positive pole, another contact connects the battery folder positive pole, one termination internal battery B1 positive pole of JD1 power supply coil, another termination aerotron Q4 collecting electrode, aerotron Q4 emitter connects the internal battery negative pole, aerotron Q4 base stage connects the battery folder positive pole by resistance R 7, and when relay J D1 adhesive, internal battery is powered to battery folder by the contact of relay J D1.The relay J D2 that the reversal connection of control battery folder is reported to the police in anti-battery folder reversal connection/short-circuit protection circuit, one of them contact connects internal battery B1 positive pole, another contact connects the flashing light control circuit, one termination product internal battery B1 positive pole of relay J D2 power supply coil, the collecting electrode of the inner photo-transistor of another termination photoelectric coupling circuit U1, the photo-transistor emitter connects battery negative post, U1 interior light emitting diodes positive pole connects the battery folder negative pole by resistance R 8, and the light-emitting diode negative pole connects on the anodal copper sheet of battery folder; Buzzer phone BU1 and resistance R 1 series connection are attempted by JD2 power supply coil two ends then.When polarity connects inverse time, have buzzer prompting and flashing light flicker warning.
Described anti-battery folder reversal connection/short-circuit protection circuit also is connected with a touch-switch K8; this switch one termination internal battery B1 positive pole; the other end is connected on the anodal copper sheet of battery folder by a diode D3 and resistance R 9; low or when open circuit when the automotive battery voltage pole; can click this switch; make the relay adhesive, to start automobile.
Electrode line has adopted double structure among Fig. 3, wiring PORTA and wiring PORTB are connected on respectively on the upper and lower copper sheet 71,72 of battery folder positive pole, wiring PORTA and wiring PROTB do not communicate under the normal condition, when battery folder 7 was clipped on the automotive battery, upper and lower copper sheet 71,72 just was communicated with by cell terminal; PORTC is connected on battery folder 7 negative poles.
When battery folder 7 discord automotive batterys joined, because no-voltage between wiring PORTB and PORTC, aerotron Q4 was in off condition, relay J D1 does not have power supply voltage, be in off-state, wiring PORTA is not charged yet, can prevent the battery folder short circuit and the harm that brings.
When battery folder 7 and automotive battery polarity connect inverse time, voltage on the PORTC is higher than PORTB, and aerotron Q4 is in anti-off condition partially, and relay J D1 continues to keep off-state, be in off-state between product internal battery and automotive battery, do not have the harm that produces big electric current.Simultaneously, automotive battery is given the power supply of photoelectric coupling circuit in-to-in light-emitting diode forward by resistance R 8, the conducting of photoelectric coupling circuit in-to-in photo-transistor, storage battery B1 gives relay J D2 and buzzer phone BU1 power supply, relay J D2 adhesive, storage battery B1 gives flash lamp circuit 3 power supplies, makes lamp L2 flicker, buzzer phone BU1 buzzing prompting.
When battery folder is connected polarity when correct with automotive battery, because the voltage of wiring PORTB is higher than PORTC, photoelectric coupling circuit U1 in-to-in light-emitting diode is in partially anti-, photo-transistor ends, therefore relay J D2 disconnects, and flashing light L2 is not luminous, and buzzer phone BU1 does not pipe yet.Simultaneously, automotive battery makes the Q4 conducting by R7, and storage battery B1 gives relay J D1 power supply, makes relay J D1 adhesive, and product internal battery B1 and automotive battery are communicated with, and can start automobile.After starting automobile and finishing, the user takes off battery folder from automotive battery, is connected in battery folder 7 anodal wiring PORTA and PORTB disconnection last 71,72 of copper sheets down, no-voltage between PORTB and PORTC, aerotron Q4 ends, and relay J D1 is disconnected, and battery folder returns to not electriferous state.
Because relay J D1 and JD2 adopt product in-to-in storage battery B1 power supply, the electronic switch Q4 and the U1 that control its adhesive are then controlled by automotive battery, it is the adhesive of may command JD1 and JD2 that automotive battery only needs the voltage about 2V, therefore, even the automotive battery over discharge does not also influence the normal function of product, can guarantee when just connecing that the reliable adhesive of relay J D1 is to start automobile, can guarantee the reliable adhesive of relay J D2 during reversal connection, to play the warning effect.
When automotive battery was opened a way fully, connected battery folder this moment, can't lean on automotive battery control relay JD1 adhesive to start automobile, this moment, the user can click touch-switch K8, because PORTA and PORTB on this moment, storage battery passes through K8, D3, R9, PORTA, PORTB and R7 make aerotron Q4 conducting, relay J D1 adhesive, and storage battery B1 is communicated with by contact and the PORTA of JD1, even K8 recovers off-state, also can guarantee the Q4 conducting, JD1 keeps attracting state, and the user can start automobile.After the startup automobile finished, the user took off battery folder from automotive battery, and the PORTA and the PORTB that are connected between the anodal upper and lower copper sheet of battery folder disconnect, no-voltage between PORTB and PORTC, aerotron Q4 ends, and relay J D1 is disconnected, and battery folder returns to not electriferous state.
The utility model also can be guaranteed under the situation of battery folder short circuit or reversal connection, press K8 and do not bring harm, when battery folder 7 short circuits, if PORTA and PORTC short circuit, then PORTB is unsettled, no-voltage between PORTB and PORTC, aerotron Q4 ends, and relay J D1 disconnects, and presses K3 exactly, also can't make the JD1 adhesive, therefore not have big electric current and produce.When PORTB and PORTC short circuit, or PORTA, PORTB is during PORTC short circuit simultaneously, voltage is 0V between PORTB and PORTC, aerotron Q4 ends, and relay J D1 disconnects, when pressing K8, relay J D1 keeps off-state, because the metering function of R9, storage battery B1 only provides mA level electric current, does not therefore have big electric current and produces.When the battery folder reversal connection, there is reverse voltage between PORTB and PORTC, aerotron Q4 ends, and relay J D1 disconnects, when pressing K8, owing to still have reverse voltage between PORTB and PORTC, relay J D1 keeps off-state, simultaneously because only there is mA level electric current in the metering function of resistance R 9 in the circuit, do not have big electric current and produce, but also Normal Alarm of reversal connection warning circuit.
