Detailed description of the invention
Below with reference to accompanying drawing of the present invention; clear, complete description and discussion are carried out to the technical scheme in the embodiment of the present invention; obviously; as described herein is only a part of example of the present invention; it is not whole examples; based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to protection scope of the present invention.
For the ease of the understanding to the embodiment of the present invention, be further explained for specific embodiment below in conjunction with accompanying drawing, and each embodiment does not form the restriction to the embodiment of the present invention.
Shown in seeing figures.1.and.2, the structure of the present embodiment is as follows:
Motor 16 is installed on housing 8, and worm screw 17 is connected on the output shaft of motor 16; End cap 12 is connected on housing 8, and housing 8 is arranged on hatch door 19; Worm gear 18 is supported on housing 8 and end cap 12 by Worm Bearing 15, and engages with worm screw 17; Crossing cabin axle 2 is supported on housing 8 and end cap 12 by crossing cabin axle bearing 5; Crossing cabin Simmer ring 20(two) be installed between crossing cabin axle 2 and hatch door 19, seal when rotating for crossing cabin axle 2; Sliding bar 3 is installed in crossing cabin axle 2, can move relative to the axis of crossing cabin axle 2; Left back-moving spring 4 and right back-moving spring 13 are installed between sliding bar 3 and crossing cabin axle 2, mediate for keeping sliding bar 3; Balladeur train 6 is installed on sliding bar 3, can move rotate with crossing cabin axle 2 with sliding bar 3, gears meshing when balladeur train 6 is positioned at centre position and on worm gear 18; Sliding bar sealing ring 21(two) be installed on sliding bar 3, and move with sliding bar 3, for sealing the gap between sliding bar 3 and crossing cabin axle 2; Idler gear 11 is supported on housing 8 and end cap 12 by idler gear bearing 7, and with the gears meshing on crossing cabin axle 2; Output gear 10 is supported on housing 8 and end cap 12 by output gear bearing 9, and engages with idler gear 11.Out of my cabin on handle 1 and cabin inner handle 14 can respectively from out of my cabin with insert crossing cabin axle 2 in cabin, the bond structure out of my cabin on handle 1 and cabin inner handle 14 coordinates with the keyway arrangements on crossing cabin axle 2, can by power transmission to crossing cabin axle 2.
Under normal circumstances, this device adopts motorized motions, and handle 1 and cabin inner handle 14 all do not insert in crossing cabin axle 2 out of my cabin.Motor 16 power is passed to output gear 10 through driving-chain and exports.Under emergency or failure condition, spacefarer will handle 1 and cabin inner handle 14 insert in crossing cabin axle 2 out of my cabin out of my cabin or in cabin, switch to manual work pattern by the interlock of mechanism, can rapidly and reliably realize manual operation.Crossing cabin Simmer ring 20 and sliding bar sealing ring 21 ensure that drive unit in the course of the work to the sealing of cabin body.
Below the course of work of the present invention is described.
Fig. 1 is the structural representation of the present invention under motorized motions pattern.Now sliding bar 3 is in the centre position of crossing cabin axle 2 under the effect of left back-moving spring 4 and right back-moving spring 13, when being in this position, and balladeur train 6 and the gears meshing on worm gear 18.Spacefarer is in cabin or out of my cabin after starter motor 16, power passes to worm gear 18 through worm screw 17, and passes to balladeur train 6 by the gear on worm gear 18, drives crossing cabin axle 2 to rotate, power passes to output gear 10 by crossing cabin axle 2 by idler gear 11, is outputed power by output gear 10.When motor 16 quits work, because worm gear 17 and worm screw 18 self-locking action make drive unit remain on stop position, hatch door can be kept to be in locking and released state.
The schematic diagram that Fig. 2 is the present invention under manual drive mode out of my cabin.Under this drive pattern, motor 16 does not work, spacefarer will insert in crossing cabin axle 2 by handle 1 out of my cabin, bond structure out of my cabin on handle 1 coordinates with the keyway arrangements on crossing cabin axle 2, handle 1 inserts and promotes sliding bar 3 in crossing cabin axle 2 process and move right out of my cabin, balladeur train 6 moves with sliding bar 3, depart from and engage, thus crossing cabin axle 2 freely can rotate with the gear of worm gear 18.Spacefarer's turning handle 1 drives crossing cabin axle 2 to rotate, and power passes to output gear 10 by crossing cabin axle 2 by idler gear 11, is outputed power by output gear 10.After manual driving operation terminates, spacefarer will extract by handle 1 out of my cabin in crossing cabin axle 2, sliding bar 3 returns back to the centre position of crossing cabin axle 2 under the effect of left back-moving spring 4 and right back-moving spring 13, thus balladeur train 6 engages again with the gear on worm gear 18, because worm gear 17 and worm screw 18 self-locking action make drive unit remain on stop position.
In cabin, manual drive mode is with drive pattern principle is identical out of my cabin, and when cabin inner handle 14 inserts in crossing cabin axle 2, promote sliding bar 3 and be moved to the left, balladeur train 6 departs from the gear of worm gear 18 and engages, and can carry out manual actuation in cabin.After having operated, cabin inner handle 14 is extracted by spacefarer in crossing cabin axle 2, and sliding bar 3 resets, and balladeur train 6 engages again with the gear on worm gear 18, and worm gear 17 and worm screw 18 self-locking action make drive unit remain on stop position.
Can to be realized in cabin by the present invention and two kinds of mode activated out of my cabin, have structure simple, quality is light, the effects such as reliable in action.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
