Description

Along stair suspension type electric vehicle device up and down

Technical field

The utility model relates to a kind of mechanical technique of riding instead of walk, particularly a kind of mechanical device of riding instead of walk for the stair up-downgoing.

Background technology

At present, mannedly finishing downstairs, the device overwhelming majority of function is to use the vertical lift elevator of designated lane, it has the waste Housing resource, complete closed operation can't realize taking with walking the shortcoming such as freely changes, and a large portion residence building does not all have lift-mounting in China, all adopt on the most original manner of walking and go downstairs, this has brought very large difficulty for old, weak, sick, residual crowd.Tool China committee for the study of problems of the aged statistics, at present China more than 60 years old elderly population reached 1.43 hundred million people, surpass 10% of total population, in addition, the population of China's physical disabilities is near 9,000,000 people, lower limb disability population is about 2,000,000 people, and the major part among these elderly and the disabled all needs dependance on wheel chair to come auxiliary moving, up and down just must be by about the stair at the building that does not have elevator.At least want plural people to be assisted because structural restriction, common wheelchair (comprising electric wheelchair) will be finished stair activity, this has caused very large inconvenience for wheelchair user's daily life.Simultaneously, there is not the residential building of elevator to bring inconvenience in life to staying in slightly higher normal person yet.

Except elevator and, in order to enlarge the range of use of wheelchair, how the researcher uses and does a lot of work aspect the speeling stairway of wheelchair both at home and abroad, mainly can be divided into three aspects:

1, improve Wheelchair structure, comprise type of drive such as adopting deformed caterpillar, joint wheel, wherein more representational is the IBOT electric wheelchair of U.S. SEGWAY company design.This wheelchair adopts the double-planet rear-wheel structure, carries out balance by the gyro mechanism of complexity, requires dorsad stair and leaning back of user when speeling stairway, as far as possible by banister promptly to assist.The wheelchair user must just can stair activity through special training, and manufacturer also still advises being assisted to finish by experienced auxiliary as far as possible, this shows the wheelchair of this kind structure, be not suitable for common corridor or customer, so its application value is little.

2, at the banister upper mounting rail, this class device be with wheelchair be connected with guide rail after under the motor draw wheelchair along the guide rail upstream or downstream, this kind structure affects normal person's walking on the one hand, in addition on the one hand in the stair corner, its difficulty very of turning, and existing a lot of banister employing is wooden, and there is great safety performance in the weight that can not bear wheelchair and user.

3, lay drop front at stair, make the part stair form an inclined-plane passage by on stair, laying drop front, be connected with wheelchair by people's non-productive operation with the power-assisted dolly and finish stair activity, successively panel is packed up again afterwards, this kind method needs the auxilian to lay and dismantles drop front, there are how many stair just to need to lay how many panels, thereby brought huge work capacity to the auxilian, be unfavorable for promotion and application.

More than three kinds of schemes, when using degree of utilization low also exist safety not high, comfort level low, existence be difficult to large scale application problem high except improvement cost.
