The specific embodiment
As shown in Figure 1, the drive controlling mechanism of the rail vehicle Electric plug sliding door that the utility model relates to comprise carry crossbeam 8, left and right bracing or strutting arrangement 2 and 11, left and right longitudinal rail 1 and 12, cross slide way, guiding rail 6, motor fork driven unit 17, cog belt 15, cingulum connector 14 and 141, driven end pulley 13, on support base plate 20 (referring to Fig. 2).Wherein,
Be respectively equipped with plug on left and right bracing or strutting arrangement 2 and 11 the inside wall and draw the longitudinal rail 1,12 of direction.Carrying crossbeam 8 is a passive section bar, and its two ends are slidingly connected through slide block and said left and right longitudinal rail 1 and 12 respectively, and can slide along left and right longitudinal rail 1 and 12, thereby makes whole mechanism fill in the motion of drawing direction.Left and right bracing or strutting arrangement 2 and 11 is fixed on Electric plug sliding door doorframe two ends through left side suspension bracket 3 and right side suspension bracket 10 respectively.
The two piece cross slide waies parallel with carrying crossbeam 8 are housed in the front of carrying crossbeam 8, on two cross slide waies, slide block are housed respectively, the left and right door leaf of Electric plug sliding door respectively with said cross slide way on the slide block radial type be connected.
At the left end that carries crossbeam 8 one motor fork driven unit 17 and drive end pulley assembly is housed also, driven end pulley 13 is housed at the right-hand member that carries crossbeam 8.Between drive end pulley assembly and driven end pulley 13, cog belt 15 is housed, cog belt 15 is back-shaped running, down on the cingulum cingulum connector 14 is being housed, and the slide block that is fixed with the Electric plug sliding door door leaf on this cingulum connector 14 and the cross slide way links to each other; One cingulum connector 141 also is housed on last cingulum, and the roller on this cingulum connector 141 moves along being installed in the curved groove that supports the guiding rail 6 on the base plate 20.
When the motor in the motor fork driven unit 17 rotates; This motor can make cog belt 15 motions through output shaft, drive end pulley, driven end pulley 13; Thereby; Drive is installed in cingulum connector 14 and 141 motions on the cog belt 15, and cingulum connector 141 moves along guiding rail 6, and cingulum connector 14 drives the slide block on the cross slide way, that be fixed with the Electric plug sliding door door leaf that is arranged on that is attached thereto and slides; And then drive the Electric plug sliding door plug and draw, i.e. the unlatching of Electric plug sliding door, close.
Closing the back locking for the door leaf that can make Electric plug sliding door, release when opening also needs a locking release mechanism.
Like Fig. 1, shown in Figure 2, this locking release mechanism comprises locking unlock component and motor fork driven unit two parts.
The locking unlock component comprises release fork 4, left fork 5, right fork 9, pull bar 7 and oscillating bearing connecting rod 16.
One end of release fork 4 links to each other with motor fork driven unit 17 through oscillating bearing connecting rod 16, and the other end is fixed on through back shaft 29 and carries on the crossbeam 8, and release fork 4 can be around back shaft 29 swings.Motor fork driven unit 17 drives release fork 4 around back shaft 29 swings through oscillating bearing connecting rod 16.
The vertical edge of left side fork 5 links to each other with an end of pull bar 7 through left oscillating bearing 28.The other end of pull bar 7 links to each other with right fork 9 through right oscillating bearing 281.
Left and right fork 5,9, pull bar 7 and left and right oscillating bearing 28,281, left and right rotating shaft 30,301 constitutes a four-bar linkage structure.
In order to make the left and right fork 5,9 can synchronization action, left oscillating bearing 28, right oscillating bearing 281 have external screw thread in the opposite direction.Said pull bar 7 two ends respectively are provided with and said left oscillating bearing 28, internal thread that right oscillating bearing 281 external screw threads are corresponding.This design can guarantee the synchronous swing of left and right fork.
Shown in Fig. 3 A, 3B, the line A among the figure represents release Oscillating lever bearing 19 actual present position lines, and line B represents locking dead-centre position line.Release fork 4, left fork 5 and release Oscillating lever bearing 19 threes' rotation center is formed a right-angled triangle in the locking dead-centre position.When plug sliding door door leaf is in closed condition; Release Oscillating lever bearing 19 is in the position (referring to Fig. 3 A) greater than 90 °; As long as the position of release fork 4 is motionless, under the power F effect of left fork 5 when pushed by the passenger, left fork 5 is unlocked fork 4 and 19 restrictions of release Oscillating lever bearing; The quadric chain that left and right fork constitutes is by locking, and door leaf can't be opened; When opening the door; Motor fork driven unit 17 is swung around back shaft 29 through oscillating bearing connecting rod 16 pulling release forks 4; And then drive release Oscillating lever bearing 19 slides in the long slot bore of left fork 5; After slipping over locking dead-centre position B line; The triangle that release fork 4, left fork 5 and release Oscillating lever bearing 19 threes' rotation center is formed becomes the on-right angle triangle, and the quadric chain that left and right fork constitutes can rotary oscillation under the effect of power F, opens thereby will fill in the door leaf of pulling.The basic principle of Here it is the utility model locking and release.
Like Fig. 4, shown in Figure 5, the motor fork driving mechanism 17 that constitutes the utility model comprises motor 25, planetary reduction gear 22, the conic reducer 21 that connects successively.The bevel gear output shaft 26 of conic reducer 21 directly is connected with the toothed belt wheel endoporus, utilizes the flat key transfer torque.Planetary reduction gear 22 shells are provided with driving pendulum rod 23; This driving pendulum rod 23 is rotationally connected with oscillating bearing connecting rod 16; And the support member 27 of these driving pendulum rod 23 both sides is provided with limiting block 24, and this support member 27 buried bearings and anti-attrition packing ring are to guarantee relatively rotating of motor housing and rotor.Said motor is a dc brushless motor, and said planetary reduction gear is the two-stage planetary reduction gear.
When motor 25 normal rotations, its power is directly passed to the output shaft 26 of conic reducer 21, drives cog belt 15 rotations and can realize the door leaf switching function.In the time just will opening door leaf, motor 25 is because of the excessive reason of mechanism's resistance, and machine shaft does not change, and the motor housing antiport drives driving pendulum rod 23 swings, and driving pendulum rod 23 drives release forks 4 and carries out release; When door leaf cuts out when soon shutting; Because the contact resistance of door leaf adhesive tape etc. increases; Motor 25 shells are relatively rotated once more, drive driving pendulum rod 23 and order about 4 backswings of release fork, get into the locking zone thereby make release Oscillating lever bearing 19 put the locking dead-centre position.Here it is, and the utility model utilizes the reaction moment of the relative rotor of motor housing to carry out locking separates lock control.Simultaneously, the motor rotary power passes to cog belt 15, and the forward and reverse motion of cog belt drives the slide block movement that is attached thereto, thereby, drive the plug sliding door door leaf that links to each other with slide block and carry out the motion of switch direction.
