The soft start circuit of the buggy is formed by a power resistor R26, charging resistors R23 and R25, charging capacitors C26 and C27, discharging resistors R22 and R24, switch triodes Q8 and Q9 and isolating diodes D8 and D9. The soft start circuit of the buggy can slow down the accelerated speed when the buggy is started and reduce buggy driving accidents due to sudden acceleration.
Description
Technical field
The present invention relates to a kind of circuit of remote control baby-carrier, especially relate to the soft-start circuit of remote control baby-carrier.
Background technology
At present, the general startup of perambulator is direct startup, connects to start perambulator behind the motor and produce a bigger acceleration/accel, bumps wall easily, and there is a potential safety hazard in the children of first driving perambulator, and this just requires perambulator, and speed needn't be too fast when starting.
Summary of the invention
The present invention is directed to the problem that prior art exists, a kind of circuit that makes the perambulator toggle speed slowly start is provided.
For practical above purpose, the present invention is achieved in that a kind of perambulator soft-start circuit, by power resistor (R26), charging resistance (R23, R25), charging capacitor (C26, C27), discharging resistance (R22, R24), switch triode (Q8, Q9), isolation diode (D8, D9) is formed.
Discharging resistance (R22), charging capacitor (C26) and isolation diode (D9) series connection, the base stage of switch triode (Q9) is connected with charging resistance (R23).
Discharging resistance (R24), charging capacitor (C27) and isolation diode (D8) series connection, the base stage of switch triode (Q8) is connected with charging resistance (R25).
Further, this circuit also comprises relay (K2) and (K3), and relay (K2) and discharging resistance (R22) and charging capacitor (C26) are connected and control the charge condition of charging capacitor (C26); Relay (K3) and discharging resistance (R24) and charging capacitor (C27) are connected and control the charge condition of charging capacitor (C27).
This circuit also comprises PTIC chip, aerotron (Q4, Q6), and the 11st pin of PTIC chip is connected with the base stage of aerotron (Q4), and the 10th pin of PTIC chip is connected with the base stage of aerotron (Q6).
This circuit also comprises relay (K5), and relay (K5) and power resistor (R26) are connected and control the break-make of power resistor (R26).
Compared with prior art, when capacitor C 26 chargings, perambulator begins to start lentamente, and aerotron Q9 conducting this moment finishes slow the startup when electric capacity does not charge.Characteristics of the present invention are: the acceleration/accel when soft-start circuit can slow down the startup of perambulator, reduce owing to accelerate to take place driving perambulator accident suddenly.
Description of drawings
Fig. 1 is perambulator start-up circuit figure.
Fig. 2 is perambulator soft-start circuit figure.
Fig. 3 starts control flow chart for perambulator is slow.
Concrete principle of work
Power resistor R26 is a kind of suppressor resistor, and power is 4W, and power resistor and positive source → relay K 2 → power cathode link together when perambulator enters slow the startup, and power resistor R26 is equivalent to be connected in parallel on not work on the lead when finishing slow the startup.
During work, perambulator advances: when the perambulator chip is received from remote controller signal, PTIC chip (radiofrequency receiving chip) the 11st pin output high level, chip the 10th pin output low level, aerotron Q4 conducting, relay K 2 adhesives, this moment, charging capacitor C26 began charging, aerotron Q9 conducting, relay K 5 flicks (being closure during no power), power supply flows to relay K 2 → power resistor R26 → motor M 1 → relay K 3 → ground from the positive pole of battery, when capacitor charging time reached 2.2 seconds, charging capacitor C26 was full of, and aerotron Q9 base stage does not have voltage so Q9 to end, K5 relay adhesive this moment, power supply flows to relay K 2 → relay K 5 → motor M 1 → relay K 3 → ground from the positive pole of battery.
Perambulator retreats: PTIC chip pin the 11st pin output low level, chip the 10th pin output high level, aerotron Q6 conducting, relay K 3 adhesives, this moment, charging capacitor C27 began charging, so aerotron Q8 base stage has voltage aerotron Q8 conducting, relay K 5 flicks (being closure during the relay no power), power supply flows to relay K 3 → motor M 1 → power resistor R26 → relay K 2 → ground from the positive pole of battery, when capacitor charging time reached 2.2 seconds, charging capacitor C27 was full of, and aerotron Q8 base stage does not have voltage Q8 to end, relay adhesive this moment, power supply flows to relay K 3 → relay K 5 → relay K 2 → motor M 1 from the positive pole of battery.
When capacitor C 26 chargings, perambulator begins to start lentamente, and aerotron Q9 conducting this moment finishes slow the startup when electric capacity does not charge.Relay K 5 closures when slow startup finishes " time, perambulator finishes to start and enter normal motoring condition.(resistance R 22, R24 is discharging resistance, and when finishing slow the startup, relay K 5 disconnects, and charging resistance R22 is just put capacitor C 26,100R is also shorter discharge time in the resistance selection).
