Description
Technical field
The present invention relates to wheelchair technical field more particularly to a kind of multifunctional wheelchairs.
Background technique
Wheelchair is the important work of old weak person and the essential walking-replacing tool of lower limb the disabled and sick and wounded Rehabilitation
Tool, it is often more important that enable them to be carried out physical exercise by means of wheelchair and participate in social activities.Wheelchair is generally divided into commonly
Wheelchair and specifical wheelchair, common wheelchair generally by wheelchair frame, wheel, brake gear and seat against four parts and form, and common wheelchair is not
Have climbing ladder and cross-country obstacle crossing function, greatly limits its use scope.
Thus, technical staff both domestic and external proposes the specifical wheelchair for much climbing building obstacle detouring, the kind of relevant apparatus and patent
There are many class, include mainly the three categories such as crawler type, wheel group formula and polypody, function and application characteristic are also to cut both ways.Such as
In turning, steel ring crawler belt damages ground very big crawler-type wheel chair；Polypody wheelchair when walking, (or the support of each wheel
Foot) it is relatively uniform to geostatic pressure, but seat jolts with wheel (or support leg) fluctuating, and the center of gravity of occupant constantly changes, and relaxes
Appropriateness is poor；Wheel group formula wheelchair is fine in smooth-riding surface barrier-free environment downward driving performance, but when stair activity or obstacle detouring, center of gravity
Change big rise and fall, occupant can be made not feel good.
The above specifical wheelchair needs switch mode when climbing building or obstacle detouring, and the structure of wheelchair is complex, and price is also more
It is expensive.Seat suspension is generally the integrated design with wheel suspension simultaneously, it means that when wheel jolts, seat is also therewith
Jolt, center of gravity is easy to happen offset, so comfort level is poor, turning, obstacle detouring or it is upper downstairs when safety it is also poor.
Although gyroscope is introduced into Wheelchair structure by some technologies, to increase the balance of wheelchair.Such as patent CN
106943248 A propose " a kind of multifunctional wheelchair ", by gyroscope measure seat inclination, by chain, gear, turbine and
The drive mechanism of worm screw rises or falls seat in suspension, thus the horizontal direction for guaranteeing seat lower to a certain degree；But due to
Its wheel and seat on same suspension frame structure, can only two front-wheels or rear-wheel obstacle detouring simultaneously, single front-wheel or rear-wheel are in obstacle detouring
When, confusion can occur for the operational mode of gyroscope, cause another front-wheel to generate hanging, cause the risk overturned, while it is tied
Structure is complicated, and spare and accessory parts are very more, and operation is not easy, and are easily damaged.
In sum, it is ensured that for the specifical wheelchair of obstacle detouring class to the adaptability of various landform, primary is exactly by wheel suspension
It is separated with seat suspension, makes the tilt mode of wheel and the tilt mode independent operating of seat, i.e., when wheel jolts, seat is basic
Keep horizontal direction, to guarantee the comfort level and safety of wheelchair, this point be also wheelchair field important brainstorm subject it
One.

The working principle of the invention: the connection type of cable wire 19 are as follows: the fixed pulley 17- angle pulley of cable wire fixed point 18-
Group another fixed another cable wire fixed point 18 of pulley 17- of another angle pulley group 23- of 23- mobile pulley 12-.As shown in Fig. 7-a,
When going upstairs, two front-wheels rise, and swing back inclined moment in seat 1 and seat suspending framework 2, solid-state precision gyroscope and acceleration
Sensor automatically determines tilt angle and inclined speed, and the tilt signals of generation are transmitted in servo-control system, according to inclining
Steering and the revolving speed of oblique signal adjustment motor 15 and screw rod 14, the precession in oscillating rod 9 and sliding sleeve 13 of screw rod 14 drive and swing
Bar 9 is swung to rear-wheel direction, and the rope between the mobile pulley 12 and angle pulley group 23 of wheelchair latter half is long at this time is reduced, accordingly
The long increase of rope between ground angle pulley group 23 and fixed pulley 17, the cable wire 19 of wheelchair latter half are in relaxed state, wheelchair
Rope length between the seat 1 and cable wire fixed point 18 of latter half also increases, and vertical range increases between wheelchair latter half and rear-wheel,
Vertical range reduces between corresponding wheelchair first half and front-wheel, that is, realizes the motor pattern that seat 1 turns forward, take people's
Center of gravity also biased forwards, improve safety upstairs；As shown in Fig. 7-c, when going downstairs, two front-wheel declines, such as aforementioned original
Manage it is similar, unlike, oscillating rod 9 to front-wheel direction swing, realize motor pattern of the seat 1 to layback, take the weight of people
The heart also deviates backward, improves safety downstairs；As shown in Fig. 7-d, when a front-wheel encounters barrier, oscillating rod 9 to
Rear-wheel direction is swung, and realizes the motor pattern that seat 1 turns forward, at the same two fixed pulleys 17 of wheelchair first half with it is right
The cable wire fixed point 18 answered is mutually adjusted, specific adjustment mode are as follows: is hung down between the front-wheel side wheelchair first half lifted and front-wheel
Straight distance reduces, and vertical range increases between the front-wheel side wheelchair first half not lifted and front-wheel, to make wheelchair first half
Divide and not only turn forward, also occurs never to lift a side of front-wheel to the angled manner for the side for lifting front-wheel, to protect
During demonstrate,proving obstacle detouring, seat 1 and seat suspending framework 2 keep horizontal direction substantially, by the connection type of pulley wire rope, when obstacle detouring
Each wheel can land, and avoid risk of overturning caused by wheel hanging；As shown in Fig. 7-b, level land when driving, without inclining
Tiltedly, oscillating rod 9 is static, travels as common wheelchair.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
