Abstract
The utility model relates to a wheelchair which can get up and down stairs. The wheelchair is composed of an upper vehicle body (1) and a lower vehicle body (15) which can relatively move in the horizontal direction, wherein, the upper and the lower vehicle bodies are respectively provided with four small wheel rods / leg rods and four supporting base rods which can move up and down. Because the upper and the lower vehicle bodies slide backwards and forwards in the horizontal direction, and the eight small wheel rods / leg rods and supporting base rods alternately rise and fall, the wheelchair can complete the action of getting up and down stairs.
Description
This utility model relates to a kind of wheelchair of energy stair activity; A portion-human lives's needs-A61G the group that belongs to International Classification of Patents.
Common wheelchair can be walked on level land and slope in easy flights, brings convenience to the people with disability, thereby is used widely.Yet common wheelchair but can not stair activity, and its application is restricted.
The purpose of this utility model is the shortcoming that will overcome prior art, and a kind of wheelchair of energy stair activity is provided.
Task of the present utility model realizes by following proposal: the wheelchair of energy stair activity comprises upper body (1), seat (2), footboard (3), handrail (4), pushing hands (5), main wheel (6) and main axle assembly (7), the total part of a pair of preceding steamboat common wheelchairs such as (8); But different with common wheelchair is: on upper body (1), have a pair of before steamboat bar (9) and preceding steamboat (8) link, also have a pair of rear support leg (10) and rear support leg bar (11) on upper body (1), preceding steamboat bar (9) and rear support leg bar (11) can move up and down with respect to upper body (1) by lifting drive (12).Below upper body (1), have one by track-type facilities (13) and upper body (1) link, and the lower body (15) that can move horizontally with respect to upper body (1) work by guide rail driving device (14), the position, front and back of lower body (15) has a pair of preceding bearing (16) and preceding seat bar (17) and a pair of rear support (18) and rear support bar (19) respectively, and forward and backward seat bar can move up and down with respect to lower body (15) by lifting drive (12).
Compared with prior art, the utlity model has significantly useful effect: common wheelchair is powerless in face of stair, not only can not manned stair activity, wheelchair itself also other need someone carries about, very inconvenient.This utility model walking on level land and the slope in easy flights, can also make wheelchair user's comfortable stair activity safely that is sitting in steadily on the wheelchair still as when level walking except can resembling common wheelchair, and need not other people help.
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is the structural representation of this utility model wheelchair.
Fig. 2 to Fig. 6 is the wheelchair process sketch map of going downstairs.
As seen from Figure 1, this utility model wheelchair is divided into two large divisions up and down, that is: upper body (1) part and lower body (15) part.This two large divisions connects by track-type facilities (13).Upper body (1) can pass through the relative in the horizontal direction slip with guide rail driving device (14) of track-type facilities (13) with lower body (15), but can not be disconnected from each other in vertical direction.Upper body partly comprises all basic elements of character of forming common wheelchair, for example upper body (1), seat (2), footboard (3), handrail (4), pushing hands (5), main wheel (6) and main axle assembly (7), a pair of preceding steamboat (8) etc.But different with common wheelchair is: on upper body (1), have a pair of before steamboat bar (9) and preceding steamboat (8) link, on upper body (1), also have a pair of rear support leg (10) and rear support leg bar (11), preceding steamboat bar (9) and rear support leg bar (11) can move up and down with respect to upper body (1) by lifting drive (12) separately, and the height of upper body (1) is changed thereupon.Before steamboat bar (9) and rear support leg bar (11) can rest on respectively on the position of differing heights, to keep the level of car body when the stair activity.A pair of preceding bearing (16) and preceding seat bar (17) and a pair of rear support (18) and rear support bar (19) are arranged on the lower body (15), and forward and backward seat bar can move up and down with respect to lower body (15) by lifting drive (12) separately.Make the height lifting thereupon of lower body (15).Forward and backward seat bar can rest on respectively on the position of differing heights, to keep the level of car body when the stair activity.Add the alternately lifting of 8 steamboat bar/supporting leg bars and seat bar owing to slide in the front and back of upper and lower car body on the wheelchair direction of advance, wheelchair just can be finished the action of upper and lower stair.
The track-type facilities (13) that connects upper body (1) and lower body (15) can adopt multiple organization plan, and present embodiment adopts the structure of two spherical guides.
The structure of above-mentioned lifting drive (12) and guide rail driving device (14) is conventional mechanical transmission structure, and what present embodiment used is screw mandrel-nut structure.When using screw mandrel-nut structure, 8 steamboat bar/supporting leg bars and seat bar are screw structure.The driving power of above-mentioned lifting drive (12) and guide rail driving device (14) is electric power, can use accumulator and direct current generator.
In the process of wheelchair stair activity, roll in order to prevent preceding steamboat (8), each steamboat is equipped with a brake unit (20) respectively.This brake unit (20) can be manpower manual, also can be electromagnetic band-type brake.
In order to increase rear support leg (10) and forward and backward bearing (16, the 18) frictional force to step surface, rear support leg (10) and forward and backward bearing (16,18) are made at the bottom of the glue.
The step width of various stair is different.In order to adapt to various step width, bearing (16) can be adjusted within the specific limits with the horizontal range of rear support (18) before requiring.For this reason, there is a crank structure (21) lower end of pro-, rear support bar (17,19), and forward and backward seat bar (17,19) links by crank structure (21) and forward and backward bearing (16,18) respectively.Adjust the position of crank (21), can adjust the horizontal range of forward and backward bearing.
The structure of lower body (15) is common steel construction, also can be other light metal structures.
Fig. 2 to Fig. 6 has shown the process that wheelchair is gone downstairs.Fig. 2: the forward and backward bearing of lower body (15) lands, and the preceding steamboat and the rear support leg of upper body (1) are liftoff slightly.Fig. 3: upper body (1) is equivalent to the distance of a step width to front slide.Fig. 4: the preceding steamboat and the rear support leg of upper body (1) land, and the forward and backward bearing of lower body (15) is liftoff.Fig. 5: lower body (15) is equivalent to the distance of a step width to front slide.Fig. 6: the forward and backward bearing of lower body (15) lands, and the preceding steamboat and the rear support leg of upper body (1) are liftoff slightly, promptly get back to state shown in Figure 2 again, and so far wheelchair is finished the action of a descending step.The course of action of going upstairs can be analogized.
This utility model wheelchair adopts driven by power, establishes panel in the wheelchair appropriate location, is used for controlling the action of all lifting drive motors and guide rail driving device motor and electromagnetic brake.Also can realize full-automatic programme-control by the PLC machine.
