Description

The double crawler belt stair-climbing wheel chair of single-unit swung based on road wheel
Technical field
This utility model relates to stair-climbing wheel chair, the frame for movement of the most wheel-track combined stair-climbing wheel chair.
Background technology
Current four-wheel wheelchair is elderly and infirm and the requisite walking-replacing tool of lower limb the disabled, but four Wheel wheelchair can not stair activity, limit range, the wheelchair user living in walk-up building cannot The most downstairs, affect it and go out to participate in social activity.China has rapidly entered aging society, and old people goes on a journey Problem is the most prominent.
In order to solve the problems referred to above, market occurs in that split type and integral type wheel carries out compound stair-climbing wheel chair.
Split type structure is to be fixed on common wheelchair to climb on building crawler belt, such as Chinese patent CN201020122939.2 discloses a kind of electric track stair-climbing vehicle, time the most downstairs, is temporarily installed at by wheelchair On electric track stair-climbing vehicle, people is sitting on wheelchair together stair activity or perron again.It is in rectangle The rear portion of crawler body arranges wheelchair carrier, and wheelchair carrier includes longeron and carrier bar, longeron lower end with Chassis is rotationally connected;Close to wheelchair carrier longeron lower end, carrier bar, carrier bar and longeron right angle are being set Intersect.The defect that this patent exists, one is: be no matter level walking or need repeatedly to split when climbing building and Assemble stairs-mover and wheelchair, bulky;Need when going out to be helped to carry by other people;Two are: platform is turned Time tilt backwards due to wheelchair, longitudinal separation is long, and the operator that wheelchair is below also needs to standing room, It is extremely difficult that this makes whole wheelchair turn at platform;Three are: whole process needs entourage and then, splits The process assembled is required for other people operation, and during climbing building be also other people in operation, especially at stair half Layer platform at, due to the device of the most anti-hypsokinesis, need people hold up slowly crawler belt from stair to level land.
Integral type crawler belt stair-climbing wheel chair has a following scheme:
1. stair-climbing wheel chair disclosed in Chinese patent CN201210590075.0, can only carry on the whole due to crawler belt or Transfer, it is impossible to fold so that wheelchair anteroposterior dimension is relatively big, causes wheelchair property passed through at stair half storey platform Bad.
2. stair-climbing wheel chair disclosed in Chinese patent CN201320833460.3, its walking bull wheel installation site is to the front, Cannot use on level land, and can not be by operator's autonomous operation.
3. stair-climbing wheel chair disclosed in Chinese patent CN201510048349.7, it is impossible to enough in operator's autonomous operation Under by the reflex angle of (angles more than 90 degree and less than 180 degree) place, the obtuse angle of stair and stair (more than 180 The angle of degree) place.
4. stair-climbing wheel chair structure disclosed in Chinese patent 201510594011.1 is complicated, and it is excellent not mention stair At angle by method, the concept feasible climbing building is poor.
5. the integral type compound stair-climbing wheel chair of wheel shoe of a entitled " explorer's stair climbing vehicle " of Italy can Under occupant's autonomous operation, steadily climb building neatly walk pacifically, but its motion is more than 4, knot Structure is complicated, build is huge, and corridor is poor by property, it is difficult to be applied to ordinarily resident building, and cost is high, is difficult to In promoting the use of.
