Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model running and power taking interlock system one embodiment.
Detailed description of the invention
Fig. 1 is the structural representation of the utility model running and power taking interlock system 1 one embodiment.In figure, 1 is running and power taking interlock system, and 2 is control or the brake portion in hand braking loop, and 3 is power takeoff cylinder, and 4 is signal lamp, and 5 is two-position three way magnetic valve, and 6 is power takeoff control cock, and 30 is electric pressure switch.
Refer to Fig. 1, for the structural representation of the utility model running and power taking interlock system 1 one embodiment, in the present embodiment, running and power taking interlock system 1 comprise: power takeoff cylinder 3, electric pressure switch 30, two-position three way magnetic valve 5 and power takeoff control cock 6.Control or the brake portion 2 in electric pressure switch 30 and the hand braking loop of automobile are connected, and the electric make break contact of electric pressure switch 30 is to being connected in two-position three way magnetic valve 5 working power loop.One group of break-make pipeline of two-position three way magnetic valve is connected in the working voltage gas pipe line of power takeoff control cock 6.Power takeoff cylinder 3 is connected with two-position three way magnetic valve 5.The electric make break contact of electric pressure switch 30 disconnects when high pressure, connects during low pressure.Two-position three way magnetic valve 5 is normally closed two-position three way magnetic valve.
In the present embodiment, running and power taking interlock system 1 also comprise signal lamp 4, and the electric make break contact of electric pressure switch 30 is to being connected in signal lamp 4 working power loop, and electric make break contact disconnects when high pressure, connects during low pressure, and after connecting, signal lamp 4 is luminous.Electric pressure switch 30 is installed in the control in the hand braking loop of automobile or any node of brake portion 2.
In the present embodiment, the critical pressure of electric pressure switch 30 is 5.5bar, and when the pressure that electric pressure switch 30 bears is higher than 5.5bar, electric make break contact disconnects; During lower than 5.5bar, electric make break contact is connected.The inlet end of two-position three way magnetic valve 5 is connected with power takeoff control cock 6, and outlet side is connected with power takeoff cylinder 3.
In one embodiment, the control in hand braking loop during running or brake portion 2 is utilized to inflate, the control in hand braking loop or the feature of brake portion 2 venting during parking, a two-position three way magnetic valve 5 is controlled by electric pressure switch 30, the break-make of power takeoff control cock 6 working voltage gas pipe line is controlled again by two-position three way magnetic valve 5, thus can not power taking when realizing driving, could the driving of power taking and power taking interlock function during parking.Specifically, when automobile is in driving, the control in hand braking loop or brake portion 2 are inflated, and therefore, the pressure that electric pressure switch bears is higher than 5.5bar, and the electric make break contact of electric pressure switch disconnects.Again because the electric make break contact of electric pressure switch 30 is to being connected in two-position three way magnetic valve 5 working power loop, one group of break-make pipeline of two-position three way magnetic valve 5 is connected in the working voltage gas pipe line of power takeoff control cock 6, when the electric make break contact of electric pressure switch 30 disconnects, two-position three way magnetic valve 5 is normally closed, the working voltage gas pipe line of power takeoff control cock 6 is input to power takeoff cylinder 3 without high pressure gas, power takeoff cylinder 3 cisco unity malfunction, namely can not power taking during driving.Otherwise, when automobile is in parking, control or the brake portion 2 in hand braking loop are exitted, the pressure that electric pressure switch 30 bears is lower than 5.5bar, the electric make break contact of electric pressure switch 30 is connected, and two-position three way magnetic valve 5 is also opened immediately, and the working voltage gas pipe line of power takeoff control cock 6 has high pressure gas to be input to power takeoff cylinder 3, power takeoff cylinder 3 can normally work, namely could power taking during parking.
The concrete enforcement of the utility model running and power taking interlock system 1, may relate to use software, but the software the used software that to be all those skilled in the art the most frequently used, and, the not claimed scope of present patent application claim.
Obviously, can the realization driving of intelligence and power taking interlock function just because of the running in the utility model embodiment and power taking interlock system 1, and mode of operation guarantee traffic safety.
The foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
