The specific embodiment
Below in conjunction with accompanying drawing, be described further this use is novel.
Such as Fig. 1-shown in Figure 4, a kind of bus passenger door anti-pinch solenoid operated directional valve, it comprises source of the gas 1 and the valve body 2 that is connected with source of the gas 1, and valve body 2 connects open the door coil 3 and the coil 4 of closing the door, and open the door coil 3 and the coil 4 of being connected connect respectively door open switch 5 and pass door switch 6; Valve body 2 is by rod chamber one end of gas circuit I 20 communicating door pump cylinders 9; And valve body 2 is installed in the sense switch I 7 on the valve body, rodless cavity one end that sense switch II 8 is passed through gas circuit II 19 communicating door pump cylinders 9 also by rodless cavity one end of gas circuit II 19 communicating door pump cylinders 9; Sense switch I 7 is connected with the sense switch II and all is connected with power supply and the coil 3 that opens the door, and the two is connected in parallel sense switch I 7, sense switch II 8.Rodless cavity one end of door pump cylinder 9 is connective protection switch 10 also, and protection switch 10 is connected with travel switch 11, and travel switch 11 connects anti-clamp circuit, and protection switch 10 and travel switch are connected with sense switch I 7, sense switch II 8.
Sense switch I 7, sense switch II 8 and protection switch 10 include housing 12; housing 12 lower ends are provided with air flue 13; at air flue 13 rubber diaphragm 14 is set; the top of rubber diaphragm 14 arranges transmission push rod 15; the top of transmission push rod 15 connects pressure spring 17 by power connecting sheet 16, and the top of pressure spring 17 arranges pressure regulating screw 18.The air flue 13 of sense switch is communicated with cylinder 9 rodless cavities one end, under door opening state, cylinder 9 rodless cavities, one end and source of the gas 1 are connected, rubber diaphragm 14 upwards promotes transmission push rod 15 under the effect of source of the gas 1 air pressure, and drive power connecting sheet 16 moves upward, compression pressure spring 17, so sense switch is in off-state at this moment.When the driver presses when closing door switch 6, cylinder 9 rod chambers, one end is connected with source of the gas 1, at this moment cylinder 9 rod chambers one end air inlet, rodless cavity one end exhaust, the passenger doors action that begins to close the door.If door-plate clips to passenger visitor in the process of closing the door, this moment, door-plate can apply a reverse power to cylinder 9 by transmission mechanism, stoped the motion of cylinder 9 pistons.When piston movement speed slowed down, the pressure of cylinder rodless cavity can descend rapidly, because the air flue 13 of sense switch is communicated with cylinder 9 rodless cavities, so the interior also rapidly decline of air pressure of air flue 13.When the air flue internal gas pressure drops to less than 0.2Mpa; the thrust that rubber diaphragm 14 makes progress is less than the downward thrust of pressure spring 17; therefore power connecting sheet 16 can move downward under the effect of pressure spring 17; the sense switch conducting; this moment, positive source was by travel switch 11, protection switch 10, sense switch I 7(or sense switch II 8) connect the electromagnetic valve coil 3 that opens the door, realization anti-pinch door opening function.
During the utility model specific works, when pressing passenger vehicle instrument desk door open switch 5, can send an instantaneous signal of telecommunication to the electromagnetic valve coil 3 that opens the door, electromagnetic valve opens the door, and coil 3 is switched on and generation magnetic force, valve rod in the middle of the pulling electromagnetic switch valve body 2 moves, a pump cylinder 9 rodless cavities one end is connected with vehicle body source of the gas 1, simultaneously door pump cylinder 9 rod chambers one end communicates with atmosphere, at this moment, the one end air inlet of door pump cylinder 9 rodless cavities, rod chamber one end exhaust, promote cylinder piston, the drive piston rod is protruding, realizes opening the door action; When pressing instrument desk pass door switch 6, the electromagnetic valve coil 4 of closing the door must conduct and produce magnetic force, the motion of attraction valve core of the electromagnetic valve, door pump cylinder 9 rod chambers, one end and source of the gas 1 are connected, cylinder 9 rodless cavities, one end and atmosphere are connected simultaneously, cylinder piston rod is retracted in cylinder under the effect of source of the gas 1 pressure, drives door leaf by passenger doors mechanism and rotates, and action begins to close the door.
The utility model sense switch and protection switch all are communicated with door pump cylinder rodless cavity one end, and sense switch is conducting when air pressure is lower than 0.2Mpa, and protection switch 10 disconnects when air pressure is lower than 0.05Mpa.Cylinder piston rod rod chamber one end air inlet in passenger doors is closed the door process, rodless cavity one end exhaust promotes cylinder piston, drives piston rod and inwardly regains, and realizes closing the door action.In this course along with the one end air inlet of cylinder rod chamber, rodless cavity one end exhaust, cylinder piston is thereupon motion also, the volume of cylinder rodless cavity end also reduces at the same time, therefore begin to this process of door-closing in-place from the action of closing the door, the air pressure of cylinder rodless cavity also is basic keep invariable (passenger doors cylinder operation air pressure range is between 0.5Mpa～0.8Mpa), and passenger doors can normally be closed and be put in place in normal unencumbered situation.If but passenger doors meets obstructions in the process of closing the door; such as clipping to the passenger; this moment is because passenger doors runs into external force; cause the cylinder piston movement velocity to reduce or stop fully; but the cylinder rodless cavity is also in normal exhaust simultaneously; therefore the air pressure of cylinder rodless cavity can reduce rapidly; when air pressure drops to less than 0.2Mpa; the sense switch conducting that is connected with the cylinder rodless cavity; owing to this moment cylinder rodless cavity air pressure be lower than 0.2Mpa and be higher than 0.05Mpa; therefore sense switch and protection switch all are in on-state; two contacts of sense switch connect with power supply and electromagnetic valve switch coil respectively; the electromagnetic valve coil that opens the door gets electricly, and passenger doors is opened, and realizes pinch resistant functionality.Because the decline of cylinder rodless cavity air pressure is very fast when clipping to the passenger, so time very short (less than 1 second) of pinch resistant functionality onset, simultaneously owing to clip to that the passenger doors clamping force is to need several seconds time progressively to increase to peaked behind the people, because the bus passenger door anti-pinch solenoid operated directional valve anti-pinch reaction time is very short, so its chucking power is very little, less than 150N.
