Operation principle of the present utility model is：Base apparatus are driven to move up and down by switching mechanism, seat 1 relies on external force
Auxiliary is overturn.The swing of flexible drive front bar 5 and rear bar 4 of the switching mechanism by electric pushrod 9 is realizing base apparatus
Lifting.Six decelerating step motors 14 are installed on chassis, decelerating step motor 14 drives six supporting legs to rotate, realizes climbing
The function of stair.During level walking, base apparatus are lifted off ground, and a pair of bull wheels 7 and a pair of steamboats 6 land, with ordinary wheel phase
Seemingly.
The process upstairs of stair climbing wheelchair is divided into three phases：Preparatory stage for climbing before building, car body be located on stair, car body
Go out flight of steps；
The preparatory stage climbed before building：In view of the safety of user, gone upstairs by the way of backward.Before going upstairs,
Electric pushrod 9 is tightened up, and drives base apparatus to decline, and six supporting legs land, seat turned over, as shown in Figure 5 a.Back leg
13 lift successively, ride on the first rank stair, while middle lower limb 12, foreleg 11 are driven along clockwise direction by decelerating step motor 14
Rotation forces wheelchair is integrally moved forward such as Fig. 5 b.Foreleg 11 is lifted, and back leg 13 is revolved on the first stage rank along clockwise direction
Turn certain angle, the afterbody on chassis 8 is gradually contacted with ground, the inclination angle of chassis 8 and horizontal plane inclination angle phase gradually with stair
Deng as shown in Figure 5 c.Foreleg 11 is continued after rotation is turned around and is contacted with ground, now back leg 13 and 11 dextrorotation simultaneously of foreleg
Turn, by wheelchair overall along stair incline direction lifting certain distance, dextrorotation after middle lower limb 12 is hanging is turned around and the first rank building
Ladder contact, such as Fig. 5 d.So far, the preparatory stage climbed before building has completed, and car body is located on stair.
Car body is located on stair：The formal building stage of climbing mainly is made up of three gaits, i.e., three groups of lower limbs are successively back to front
Lift, foreleg 11 is lifted again after back leg 13 lands, so circulate, advance similar to the wriggling of insect.As fig 5d, back leg 13
The maximum position of vertical distance is reached, central lower limb 12 and foreleg 11 continue the band motor vehicles bodies oblique upper movement that turns clockwise
When, back leg 13 is just hanging.Six supporting legs are all rotated clockwise, but 13 turns of back leg is fast, after hanging clockwise
Higher leveled step, such as Fig. 5 e touched after rotation again, Fig. 5 f, wherein, Fig. 5 e are car body when second-order stair lifting
View, Fig. 5 f leave car body view during the first rank stair for foreleg.After back leg 13 lands, foreleg 11 is lifted again
Rise, such as Fig. 5 f.When in after foreleg 11 is hanging, lower limb 12 continues to rotate clockwise with back leg 13, car body continues to move along oblique upper, turns
Back leg 13 is contacted with higher leveled step after rotating a circle faster, as shown in fig. 5g.Now wheelchair has risen a platform
Rank.Middle lower limb 12 has reached the maximum position of vertical distance again.Six supporting leg is rotated further, and middle lower limb 12 is hanging, in the air with compared with
Fast speed is contacted with higher leveled step after turning around, and back leg 13 and foreleg 11 are also suitable with slower speed in this process
Hour hands are rotated, and car body continues to move along oblique upper, as shown in figure 5h.It is that back leg 13 is lifted again afterwards, so circulation is gone down.Whole
During individual the bottom surface on chassis 8 always with stair EDGE CONTACT, can so make chassis 8 identical with stair inclination angle, center of gravity rise and fall
It is little, the pressure to supporting leg can also be reduced.
View when having gone out stair for the first half of car body.
View when Fig. 5 k have gone out stair for the major part of car body.
Climb out of view during stair for car body completely.
Fig. 5 m are the car body view after adjusting wheelchair angle.
Fig. 5 n land for chassis after car body view.
Car body goes out flight of steps：When wheelchair climbs to the stair end soon, it is parallel with the bottom surface on chassis 8 that back leg 13 goes to tangent line
Position when, stop operating.As shown in figure 5i.Middle lower limb 12 and foreleg 11 are rotated further, and wheelchair continues tiltedly upper movement, such as Fig. 5 j institutes
Show.Central lower limb 12 go to tangent line it is parallel with the bottom surface on chassis when also stop operating, foreleg 11 is rotated further, and wheelchair continues tiltedly upper shifting
It is dynamic, as shown in figure 5k.As most of weight is all on right side after a wheelchair tiltedly upper mobile segment distance, wheelchair is just in action of gravity
Under rotate clockwise, be changed into level, as shown in Fig. 5 l.Foreleg 11 continues to turn, six supporting legs after foreleg 11 is contacted with ground
All rotate clockwise, the translation of wheelchair oblique upper, as shown in figure 5m.Six supporting legs are further continued for rotating, and make the bottom surface on chassis land,
As shown in figure 5n.So far, climb building process to terminate.
Downstairs process with climb building similar process, the simply above-mentioned inverse process for climbing building process, and the bottom surface on chassis againsts building
Terraced edge, rotates realization successively by three groups before, during and after six supporting legs point and goes downstairs.
This utility model has the function of level land, stair dual-purpose, common wheelchair is can be used as at level land and is used, on stair
Complete to climb building by when only needs wheelchair one people of person or downstairs process；It is simple to operate, easy to use, and have simple structure,
The relatively low advantage of cost, is particularly suited for the handicapped people such as the old,weak,sick and disabled.
Above-mentioned embodiment is not that, to restriction of the present utility model, this utility model is also not limited to the example above,
Change, remodeling, addition or replacement that those skilled in the art are made in the range of the technical solution of the utility model,
Also belong to protection domain of the present utility model.
