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.
Embodiment
As shown in Figure 2, be the assembly axis side figure that goes downstairs on the wheelchair, the device of going downstairs on the described wheelchair comprises spindle motor 141 and the line slideway 15 that is connected with wheelchair montant 16, line slideway 15 is articulated and connected with wheelchair montant 16.Spindle motor 141 connects leading screw 14, and spindle motor 141 can drive leading screw 14 rotations.Leading screw 14 comprises left-handed part and dextrorotation part, the left-handed part of leading screw 14 is connected with dextrorotation and is respectively connected a feed screw nut 13, two feed screw nut 13 hinged the first montant 10 of difference and the second montants 11, the first montant 10 and the second montant 11 each hinged two slide block 12 of being located on the line slideway 15, slide block 12 can be along line slideway 15 smooth and easy slips, two slide blocks 12 that are connected with the first montant 10 are affixed upper hanger 5 and middle hanger 6 respectively, two slide blocks, the 12 respectively affixed decelerators 2 and lower hanger 7 that are connected with the second montant 11, upper hanger 5 is located at getting on the right track on 8 of paralleling with balustrade, middle hanger 6 and lower hanger 7 are located on the lower railway 9 that parallels with balustrade, decelerator 2 connection reducer motors 21 and gear 3, gear 3 be located at get on the right track 8 with lower railway 9 between tooth bar 4 be meshed.Upper hanger 5, middle hanger 6 and lower hanger 7 consist of suspension arrangement, described upper hanger 5 comprises support, support is provided with a locating wheel 17 and a support roller 18, described middle hanger 6 comprises support, support is provided with a locating wheel 17 and a support roller 18, described lower hanger 7 comprises support, and support is provided with a support roller 18.
As shown in Figure 1, for on the wheelchair downstairs device be installed at shaft side figure on the wheelchair, wheelchair by means of described suspension arrangement be suspended on be installed in step one side be parallel to each other square get on the right track 8 and lower railway 9 on, decelerator motor 21 by take accumulator jar 1 as power supply drive decelerators 2 driven wheels 3 be installed in get on the right track 8 and lower railway 9 between and with it parallel tooth bar 4 be meshed realization wheelchair moving up and down along guide rail.
As shown in Figure 3 and Figure 4, during beginning, spindle motor 141 drives leading screw 14 and rotates, and two feed screw nuts 13 make progress respectively, move downward about making, and then go up hanger 5 and decelerator 2, and 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.
As shown in Figure 5 and Figure 6, make again spindle motor 141 counter-rotatings, make up and down two feed screw nuts 13 respectively downwards, move upward, adjust simultaneously the wheelchair front and back position in good time, gear 3 is meshed with tooth bar 4, until suspension arrangement clamp get on the right track 8, behind the lower railway 9, operation decelerator motor 21 rotates, and makes gear 3 in tooth bar 4 motions, then drives wheelchair, realize about the moving horizontally, tilt of wheelchair, the action such as flat bank, such as Fig. 7～shown in Figure 9.Downstairs device is opposite with the above-mentioned operation that this installs grip track with the disengaging of track on this wheelchair.
Because decelerator 2 is worm type of reduction gearing, utilize the self-locking property of worm and gear, guaranteed that gear 3 can only a direction rotation and can not reverse, thereby avoided the voluntarily landing of wheelchair on tooth bar 4.
Owing to get on the right track 8 and lower railway 9 spacings be steady state value, this just guaranteed wheelchair downstairs in the process wheelchair user remain horizontal sitting posture.
