Abstract
The invention provides a wheelchair and an operation method thereof. According to the technical scheme, hand wheel rings of a traditional wheelchair are removed, and ratchet wheel drive rods capable of resetting automatically are mounted on hubs of vehicle wheels. The ratchet wheel end of each ratchet wheel drive rod is fixed on the hub of the vehicle wheel, and the other end of the ratchet wheel drive rod is a free end, which can carry out reciprocated circular motion around the axle, and act to drive the wheelchair to move. The ratchet wheel drive rods are provided with elastic pieces for connection with a frame, and after acting, under drive of the elasticity of the elastic pieces, the ratchet wheel drive rods automatically reset to the initial position. Due to change of the force application mode and direction, a user can drive with arm force or elbow force, which is far powerful than the wrist force; meanwhile, due to the lever principle of the ratchet wheel drive rods capable of resetting automatically, the patient can relatively conveniently operate the wheelchair and can save abundant force, the patient with the handicapped lower limbs can move for a long distance conveniently, and thus the patient with the handicapped lower limbs is enabled to go out conveniently.
Description
Technical field:
The present invention relates to medical care equipment field, particularly relate to a kind of wheelchair and operational approach thereof.
Background technology:
Wheelchair is the important tool of rehabilitation, and it is not only the walking-replacing tool of limbs the disabled and handicapped personage, the more important thing is and makes them carry out physical exercise by means of wheelchair and participate in social activity.Common wheelchair is generally made up of by four parts wheelchair frame, wheel, brake gear and seat.
Hand rim by wheelchair exclusive, diameter is 5cm less of large wheel rim usually, is generally directly promoted by wrist by patient.For being easy to drive, the change of following manner can be had: (1) add rubber etc. on hand rim surface to increase frictional force.(2) increase along hand rim surrounding and promote handle.But due to position and the size factor of seat, brachium, wheel rim, and be unfavorable for that occupant exerts a force, the conversion effect of wrist power is also very poor, therefore, can design one makes patient more laborsaving when using wheelchair, more convenient, more easily operate? is strength conversion effect better? facilitate the long distance walking of lower limb disabled, lower limb disabled trip wheelchair more easily can be made?
Summary of the invention:
Of the present invention can automatically reset sour jujube center wheel drive power wheelchair be traditional push chairs hand rim removed, and wheel is installed can automatically reset ratchet drive rod, and patient is by pulling the pull bar before seat downwards or with elbow pressing plate, just can driving to move.Owing to changing force mechanism and force direction, occupant can drive by arm strength or elbow power, more strong more than wrist; Meanwhile, due to the lever principle in automatically reset ratchet drive rod, patient is more convenient laborsaving, greatly facilitates the long distance walking of lower limb disabled, lower limb disabled can be made to go on a journey more convenient.
Of the present inventionly can the ratchet end of automatically reset ratchet drive rod be fixed on the wheel hub of wheel, the other end be free end.Under arm strength or the effect of elbow power, ratchet drive rod does circular motion downwards around axletree.Ratchet drive rod, by shaft driving pawl rotating-wheel, drives car motion.The corresponding wheel steering angle of the upper and lower stroke S of ratchet drive rod is about 90 °, and L is the longest for the arm of force, and power loss is minimum, and strength conversion effect is best.When ratchet drive rod moves to lower limit position, under the elastic force effect of elastic component, automatically return to upper extreme position, prepare the acting process entering next round, go round and begin again.
The technical solution adopted for the present invention to solve the technical problems:
A kind of wheelchair and operational approach thereof is characterized in that: traditional push chairs hand rim removed, two ratchet drive rods are symmetrical, cocurrent and parallel, and be arranged on two hubs for vehicle wheel of left and right with identical inclination angle, wheel is arranged on axletree; The ratchet end of ratchet drive rod is fixed on the wheel hub of wheel, and the other end is free end; Free end is connected with pull bar or pressing plate, does reciprocal circular motion around axletree; Ratchet drive rod is connected with the elastic component be fixed on vehicle frame, and after acting terminates, driven by the elastic force of elastic component, ratchet drive rod automatically returns to initial position; Described elastic component is extension spring; Described elastic component is leaf spring; Described elastic component is gas spring; Described elastic component is stage clip; Described elastic component is torsion spring.
The invention has the beneficial effects as follows: wheelchair of the present invention is installed on hub for vehicle wheel can automatically reset ratchet drive rod, changes force mechanism and force direction, occupant can drive by arm strength or elbow power, more strong more than wrist; Meanwhile, due to the lever principle in automatically reset ratchet drive rod, patient is more convenient laborsaving, greatly facilitates the long distance walking of lower limb disabled, lower limb disabled can be made to go on a journey more convenient.

Detailed description of the invention
In the embodiment shown in fig. 1, a kind of wheelchair of the present invention is removed traditional push chairs hand rim, and wheel (3) wheel hub is installed ratchet drive rod (11).Two ratchet drive rods (11) are symmetrical, cocurrent and parallel, and be arranged on two wheels (3) wheel hub of left and right with identical inclination angle, wheel is arranged on axletree (2).The ratchet end (10) of ratchet drive rod (11) is fixed on the wheel hub of wheel (3), and the other end is free end.Free end does reciprocal circular motion around axletree (2).Elastic component in the present embodiment is extension spring (12), and one end is fixed on vehicle frame (1), and one end connects ratchet drive rod (11).
When needing to advance, occupant pulls the pull bar (14) before seat downwards, and by ratchet drive rod (11) shaft driving pawl rotating-wheel (3), acting drives to move ahead.Elastic component extension spring (12), by ratchet drive rod (11) stretcher strain, stores energy storage capacity.When ratchet drive rod (11) moves to lower limit position, stop doing power motion.
The ratchet drive rod (11) being in lower limit position, under the elastic force effect of elastic component extension spring (12), automatically returns to upper extreme position, prepares the acting process entering next round, goes round and begins again.
In the embodiment depicted in figure 2, only and embodiment illustrated in fig. 1ly change gas spring (16) into unlike elastic component.Elastic component gas spring (16) one end is fixed on vehicle frame (1), and one end connects ratchet drive rod (11).When ratchet drive rod (11) moves downward, compressing elastic component gas spring (16) distortion, stores energy storage capacity.Ratchet drive rod (11) moves to lower limit position and stops doing power motion.Elastic component gas spring (16) release stores energy storage capacity, restores to the original state, ratchet drive rod (11) is returned back to upper extreme position, prepares the acting process entering next round, goes round and begins again.
At Fig. 3, in 4 embodiments, conveniently C5 spinal injury patient, finger motion critical constraints and the patient that can not clench fist, and suffer from osteoarthritis, heart disease or elderly patients, make the pull bar (14) before seat into pressing plate (13).Elbow arm is placed on pressing plate (13) by the person of taking advantage of, and by bending the acting of elbow power, drives to advance.
