Abstract
The present invention relates to wheelchair technical field, a kind of traveling mechanism of stair-climbing wheel chair is disclosed, it is characterised in that：It is made up of 3 wheels, 3 small wheel sprockets, driving chain, support, 1 center sprocket wheel, 3 expansion tightening wheels；The support is that triangle is star-like；The wheel diameter is much larger than in small wheel sprocket, and three angles rack-mount with steamboat sprocket coaxiality；The center sprocket wheel is arranged in carriage center；The expansion tightening wheel is arranged at the circumference of three wheels；The above-mentioned all wheels of the driving chain series connection, constitute wheel group structure, each wheel can be made to rotate.The wheel group structure that the present invention is constituted using three wheels, device center of gravity rises and falls less during stair activity, and more safe, simple in construction, light quality, motion is flexible.
Description
Technical field
The present invention relates to wheelchair technical field, more particularly, to a kind of traveling mechanism of stair-climbing wheel chair.
Background technology
Wheelchair is elderly and infirm and the essential walking-replacing tools of lower limb the disabled, but common wheelchair does not possess and climbed
Going upstairs and the function across roadblock, greatly limit it and use scope.The type of current stair-climbing device traveling mechanism, mainly
It is wheel group formula Stair climbing device.Wheel group formula Stair climbing device is compared with the device of other configurations, light quality, and motion is flexible, without barrier
Hindering under environment has preferably action performance.But device center of gravity big rise and fall during stair activity, occupant can be made not feel well.
The content of the invention
It is an object of the invention to the above mentioned problem for solving prior art appearance, there is provided a kind of traveling machine of stair-climbing wheel chair
Structure, the wheel group structure constituted using three wheels, device center of gravity rises and falls less during stair activity, safe, simple in construction, light weight
Just, move flexible.
A kind of traveling mechanism of stair-climbing wheel chair, it is characterised in that：By 3 wheels, 3 small wheel sprockets, driving chain, branch
Frame, 1 center sprocket wheel, 3 expansion tightening wheel compositions.The support is that triangle is star-like.The wheel diameter is much larger than small wheel sprocket, and
On three angles rack-mount with steamboat sprocket coaxiality.The center sprocket wheel is arranged in carriage center.The expansion tightening wheel
At the circumference of three wheels.The above-mentioned all wheels of the driving chain series connection, constitute wheel group structure, can make each wheel
Son can be rotated.
Turning torque when traveling mechanism climbs building needed for wheel carrier is maximum, and the fluctuating at wheel pack support center is also maximum.With small
The increase of number is taken turns, the turning torque needed for wheel pack support reduces, and the fluctuating at group wheel carrier center reduces, but structure is also multiple therewith
It is miscellaneous, therefore the wheel group structure that the present invention is constituted using three wheels.
Beneficial effects of the present invention：
Center of gravity fluctuating smaller, light quality during stair activity of the present invention, motion is flexible, simple in construction.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the overall structure figure of the present invention；
In figure：1. wheel, 2. small wheel sprockets, 3. driving chains, 4. supports, 5. center sprocket wheels, 6. expansion tightening wheels.
Embodiment
The preferred embodiments of the present invention are described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly being defined so as to be made to protection scope of the present invention.
The structural representation of the present invention is as shown in figure 1, a kind of traveling mechanism of stair-climbing wheel chair, it is characterised in that：By 3 cars
Wheel 1,3 small wheel sprockets 2, driving chain 3, support 4,1 center sprocket wheel 5,3 expansion tightening wheels 6 are constituted.The support 4 is triangle
It is star-like.The diameter of wheel 1 is much larger than in small wheel sprocket 2, and three angles being coaxially mounted to small wheel sprocket 2 on support 4.Institute
Center sprocket wheel 5 is stated on the center of support 4.The expansion tightening wheel 6 is arranged at the circumference of three wheels 1.The driving chain 3
Connect above-mentioned all wheels, constitute wheel group structure, each wheel can be made to rotate.
The course of work of the present invention：Power intake drives center sprocket wheel 5 to rotate, and center sprocket wheel 5 passes through driving chain 3
Small wheel sprocket 2 is driven to rotate, so as to realize the rotation of 3 wheels 1.When level land is travelled, train is fixed shaft gear train, any two car
Wheel 1 lands, and realizes and moves ahead；When running into obstacle or stair, using a clutch by support 4 and power input shaft be linked to be one it is whole
Body, fixed shaft gear train develops into planetary gear train, drives support 4 to overturn, so as to realize obstacle detouring and stair climbing.
Although describing embodiments of the present invention, patent owner can be within the scope of the appended claims
Various deformations or amendments are made, as long as no more than the protection domain described by the claim of the present invention, all should be in the present invention
Protection domain within.
