The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiments of the present invention relate to the device of going downstairs on a kind of wheelchair, as depicted in figs. 1 and 2, comprise the first montant 10, the second montant 11 and wheelchair montant 16, and described wheelchair montant 16 top and bottom are fixed with respectively line slideway 15; Described the first montant 10 upper ends are connected with hanger 5, and the lower end is connected with middle hanger 6; Described upper hanger 5 is installed on the line slideway 15 of wheelchair montant 16 upper ends by slide block 12; Described middle hanger 6 is installed on the line slideway 15 of wheelchair montant 16 lower ends by slide block 12; Described upper hanger 5 and middle hanger 6 slide at line slideway 15 by the mode of lead screw transmission; Described the second montant 11 upper ends are connected with driven wheel 3, and the lower end is connected with lower hanger 7; Described driven wheel 3 is positioned at hanger 5 belows, and is installed in by slide block 12 on the line slideway 15 of wheelchair montant 16 upper ends; Described driven wheel 3 drives by accumulator jar 1; Described lower hanger 7 is arranged in hanger 6 belows, and is installed in by slide block 12 on the line slideway 15 of wheelchair montant 16 lower ends; Described driven wheel 3 and lower hanger 7 slide at line slideway 15 by the mode of lead screw transmission.Be provided with decelerator 2 between described driven wheel 3 and the accumulator jar 1, wherein, described decelerator 2 is worm type of reduction gearing.Be provided with the leading screw 14 that links to each other with spindle motor 141 between described wheelchair montant 16 and the second montant 11; Described leading screw 14 two ends are equipped with feed screw nut 13, and wherein, a feed screw nut 13 links to each other with the first montant 10, and another feed screw nut 13 links to each other with the second montant 11.Support roller 18 is installed on the crossbeam of described upper hanger 5, locating wheel 17 is installed on the column of side.Described middle hanger bracket 6 is the inverted L-shaped structure, and support roller 18 is installed on the horizon bar of described inverted L-shaped structure, vertically on the bar locating wheel 17 is installed.Described lower hanger bracket 9 L-shaped structures, the horizon bar of described L shaped structure is provided with support roller 18.
As shown in Figure 3, during beginning, spindle motor 141 drives leading screws 14 and rotates, make be positioned at leading screw up and down the feed screw nut 13 at two ends make progress respectively, move downward, then go up hanger 5 and decelerator 2, middle hanger 6 is widened same distance respectively with the spacing of lower hanger 7.
Then, the wheelchair user operates wheelchair, and the device of going downstairs on the wheelchair is placed in the track perpendicular, and the locating wheel 17 of hanger 6 is tangent with lower railway 9 sides in this moment.
