Summary: | To provide a vehicle automatic opening/closing door device that can be easily installed in an existing vehicle and can reliably detect a foreign object being caught or drawn in and can eliminate such a state.SOLUTION: A vehicle opening/closing door 1 includes: an air cylinder 2 installed horizontally at one of top and bottom portions of a vehicle entrance/exit; doors 3A and 3B that open and close with a horizontal movement of a piston rod 2a of the air cylinder; an air piping 5 that can supply air from an air source 4 into the air cylinder; a supply/exhaust switching valve 6 provided in the air piping to supply/exhaust the air into/from the air cylinder; a pressure sensor 18 for detecting the air pressure inside the air cylinder; and a control unit 17 which switches the supply/exhaust direction of a supply/exhaust switching valve to switch the opening/closing operation of the door on the basis of the air pressure detected by the pressure sensor when a foreign matter is jammed during the closing operation of the door or when the foreign matter is drawn into a door pocket in which the door is housed during the opening operation.SELECTED DRAWING: Figure 1
【課題】既存車両への設置に容易に対応することができ、異物の挟込み又は引込みを確実に検出してその状態を解消することができる車両用自動開閉扉装置を提供すること。【解決手段】車両用自動開閉扉装置1は、車両の乗降口の上下一方に水平に設けられるエアシリンダ2と、エアシリンダのピストンロッド2aの水平移動に伴って開閉動作する扉3A,3Bと、エアシリンダ内部にエア源4からのエアを供給可能としたエア配管5と、エア配管に介設され、エアシリンダ内部にエアを給排気する給排気切換弁6と、エアシリンダ内部のエア圧を検知する圧力センサ18と、扉の閉動作中に異物の挟込みが発生するとき、又は開動作中に扉が収納される戸袋への異物の引込みが発生するときに圧力センサが検知するエア圧に基づいて給排気切換弁の給排気方向を切り換え、扉の開閉動作を切り換える制御部17とを備えている。【選択図】図1 |
