Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, electric motor car power assisting described in the utility model is braked used electric vacuum pump controller and is had vacuum pressure sensor 3, press first relay 1 and second relay 2 that latching circuit connects, vacuum pressure sensor 3 is produced high by circuit changing switch, lowpressure thresholding control signal, first relay 1 is according to lowpressure thresholding control signal that vacuum pressure sensor 3 produced and disconnect the power supply of vaccum pump motor, and with this off state self-locking, the highpressure thresholding control signal that the second lock relay 2 is responded to according to vacuum pressure sensor 3 and make first relay 1 lose self-locking is recovered to power to vaccum pump motor.
Wherein, the low air pressure switch contact of vacuum pressure sensor 3 circuit changing switches is connected with the coil of first relay 1 with after the normally open contact of first relay 1 is in parallel again, inserts both ends of power, constitutes latching circuit; The high gas pressure switch contact of vacuum pressure sensor 3 circuit changing switches is connected with the coil of second relay 2, inserts both ends of power; The normally closed interlock interpolation of second relay 2 is connected in the described latching circuit, cuts off the power supply of first relay, 1 coil during with realization highpressure threshold value.
When installing and using above-mentioned Motorized vacuum pump controller, the normally closed interlock of first relay is connected with vaccum pump motor, insert both ends of power.The power supply of the power supply of vaccum pump motor and vacuum pump controller can be inequality.
The circuit changing switch working procedure of vacuum pressure sensor is: the air pressure that the pneumatics force transducer of taking seriously is responded to is during more than or equal to highpressure threshold value p1, and the high gas pressure switch of circuit changing switch is connected, thereby produces highpressure thresholding control signal.The air pressure that the pneumatics force transducer of taking seriously is responded to is during smaller or equal to lowpressure threshold value p2, and the low air pressure switch of circuit changing switch is connected, thereby produces lowpressure thresholding control signal.During greater than p2, circuit changing switch is unsettled, does not produce control signal less than p1 for the air pressure that the pneumatics force transducer of taking seriously is responded to.
Certainly, vacuum pressure sensor also can be with two sensors independently, and one of them sensor is used to respond to highpressure, and another sensor is used to respond to lowpressure, and the combination of two sensors can realize the circuit conversion of high and low air pressure gear equally.
For realizing above-mentioned functions, in concrete application, multiple circuit connection structure can be arranged, only be illustrated for two example two below.
In first kind of embodiment shown in Figure 2, the Motorized vacuum pump controller includes first relay 1, second relay 2 and vacuum pressure sensor 3, the common port K1 of first relay 1, the common port J1 of power supply one end and vacuum pressure sensor 3 links together, the control input end K2 of first relay 1, the lowpressure connecting end J2 of vacuum pressure sensor 3, the Chang Kaiduan K4 of first relay 1 links together, the normal-closed end K3 of first relay 1 links to each other with the power supply the other end by the vaccum pump motor of required control, the control output end K5 of first relay 1 is through the common port K6 of second relay 2, normal-closed end K8 links to each other with the power supply the other end, the control input end K7 of second relay 2 links to each other with the highpressure connecting end J3 of vacuum pressure sensor 3, and the control output end K10 of second relay 2 links to each other with the power supply the other end.
