The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1 and Fig. 2, the drag-line shutdown system of this automobile-used automatic door comprises driving mechanism that is installed in the housing 19 and the reel that links with driving mechanism, wherein, housing 19 is fixed on the carriage 20, and carriage is installed in above-mentioned driving mechanism assembly under the foot rest of vehicle body by its preceding installation foot 4, back installation foot 10 again.Driving mechanism is made up of motor 16, clutch and reducing gear.Clutch adopts conventional electromagnetic clutch, and it includes flange 26, armature 24 and body 15, links to each other with spring leaf 25 between flange and the armature, with permission armature 24 energy axial floats; Body 15 links with motor 16 output shafts.And reducing gear is formed by being fixed on driving gear 14 on the electromagnetic clutch flange and the driven gear 8 that is positioned on the reel.When motor and clutch are all switched on, armature 24 and body 15 adhesive mutually, motor output shaft rotates, and drives driving gear 18, driven gear 8 rotations by clutch body, armature, and reel is rotated.
Described reel is made up of first line wheel, 30 and second line wheel 27 that removably connects again, and as shown in Figures 2 and 3, above-mentioned driven gear 8 and second line wheel 27 are made integral piece.Simultaneously, the obverse middle part of taking turns at first line wheel and second line all has groove, space content after each groove closes up is received the pre-bearing up pulley 29 of end face band ratchet 36, accordingly, is provided with the gear ring 33 that is meshed with this pre-bearing up pulley at the bottom portion of groove that is positioned on first line wheel.And on the outer face of first line wheel, second line wheel respectively one be shaped on the coaxial clyinder of hollow, each cylinder is bearing on the housing 19 by bearing 31, to become the main shaft of reel.Rotating shaft one end of above-mentioned pre-bearing up pulley 29 stretches in the cylinder of first line wheel 30, and exposes and become the operating side, and has hexagonal indentations 32 on the end face of this operating side, so that match with general die nut.The other end of above-mentioned pre-bearing up pulley rotating shaft then is bearing in the cylinder of second line wheel 27, and be with a back-moving spring 28, this back-moving spring one end is against on the cylinder of second coil 27, the other end is inconsistent with the end face of pre-bearing up pulley 29, makes pre-bearing up pulley have the trend of taking turns 30 side shiftings to this first line all the time.In order to realize removably connecting between first line wheel and second line wheel, in the present embodiment, also be provided with tapped alignment pin 35 on first line wheel end face relative with second line wheel, and have axially extending bore 34 at second line wheel end face, positioning bolt passes these axially extending bore 34 backs and is threaded mutually with above-mentioned alignment pin 35, thereby first line wheel, 30 and second line wheel 27 can be dismantled as required.
The preceding guide holder 1 of fixed pulley 23 before the leading section of above-mentioned foot rest is fixed with band, the rearward end of foot rest then is fixed with the back guide holder 13 of band back fixed pulley 22, fore stay 2, one end of backstay 12 is connected on the automatic door by following hinge guide 5 respectively, the other end of fore stay 2 is then walked around the preceding fixed pulley 23 that is bearing on the vehicle body, and after the other end of backstay 12 walks around the back fixed pulley 22 that is supported on the vehicle body, before being somebody's turn to do, the other end of backstay passes housing 19 walls again, be wrapped in above-mentioned second line wheel with direction respect to one another, on first line wheel, and the other end that is wrapped in the back fore stay on this first line wheel is positioned on the fixing hole 37 of this pre-bearing up pulley 29.
In order to protect drag-line; flexible pipe 3 before being with outside the drag-line between preceding fixed pulley 23 and housing 19; equally; also be with rear hose 11 outside the drag-line between back fixed pulley and housing; so both can prolong the application life of drag-line; can change the installation site of driving mechanism, to satisfy the installation needs of different automobile types by adjusting the length of each flexible pipe again simultaneously.Simultaneously, in driving gear 14 sides the encoder 17 of routine techniques is installed also, this encoder is meshed with driving gear 14 by pinion 18, knows the position of automatic door automatically, exports pulse then, the stopping of control motor.
During use, starter motor 16 is passed to reel by clutch, reducer rotatablely moving, along with the rotation of reel.When fore stay is wrapped in second line wheel when going up, backstay discharges from first line wheel, thus by under the hinge guide to left movement, the automatic door action of closing the door.Otherwise when backstay is wrapped in first line wheel when going up, fore stay discharges from second line wheel, moves right by following hinge guide, makes the automatic door action of opening the door.
The motor outage, after the clutch dead electricity, above-mentioned automatic door just can adopt manual mode to open or close action.
When in use, pine appears in each drag-line when overstating, be inserted into die nut in the hexagonal indentations 32 of aforesaid operations end, and do push action, with compression reseting spring 28, force pre-bearing up pulley 29 to take turns 27 side shiftings, the gear ring 33 on the ratchet 36 on the pre-bearing up pulley and first line wheel is separated to second line; Then rotate die nut again, pre-bearing up pulley 29 rotates thereupon, and at this moment, backstay is wrapped on the pre-bearing up pulley, and the drag-line of system outside shortens, and can eliminate the absent-mindedness phenomenon of drag-line; Unclamp the operating side of pre-bearing up pulley 29 at last, pre-bearing up pulley 29 is under the effect of back-moving spring 28, to first line wheel side shifting, gear ring on ratchet and first line wheel on the pre-bearing up pulley is meshed and unitary rotation again, makes native system can under the drag-line tensioning state, carry out the pass or the closed operation of automatic door again.
Consider in the use, can make each drag-line reach certain pretightning force, reel and before, be respectively arranged with strainer between the back fixed pulley, as shown in Figure 1 and Figure 4, each strainer comprises regulating wheel 6, tensioning frame 21 and movable pulley 9, wherein, regulating wheel 6 is bearing on the driving mechanism shell 19 by axis of rotation 38, one end of tensioning frame 21 is set on the axis of rotation 38, movable pulley 9 is positioned on the other end of tensioning frame 21 by turning cylinder 39, the drag-line of respective side passes through between regulating wheel 6 and movable pulley 9 separately, simultaneously also be provided with torsion spring 7 on axis of rotation 38 separately, an end of this torsion spring is positioned on the housing 19, and the other end is fixed on the tensioning frame 21, forcing each movable pulley to be subjected to have the trend of answer all the time behind separately the drag-line pressure, thereby guarantee that each drag-line has a pretightning force all the time.
