Abstract
一种轮椅驱动机构，安装在通用人力轮椅车轮轴(13)上，轮椅可方便的实现较长距离的出行：将摇杆机构通过滚柱式单向离合器(8)与车轮轴(13)相联接，当用手通过手把(7)向前推动摇臂(6)时，外环(1)与内环(2)将滚柱(3)往外挤压，使滚柱式单向离合器(8)与车轮轴(13)接合，带动大车轮(9)转动，驱动轮椅向前移动；当用手通过手把(7)向后推动摇臂(6)时，复位弹簧(5)向右拉动滚柱(3)，使滚柱式单向离合器(8)脱离，大车轮(9)靠惯性继续转动，轮椅继续向前移动。两前轮通过固联在前轮的转向连杆(17)同时转动，实现两前轮同步转向。本实用新型的主要用途是，让行动不方便人群通过操作轮椅的摇杆机构，非常方便省力，能够保证使用者自助驱动轮椅，提高残疾人的生活自理能力，非常适用于残疾人群。
A wheelchair driving mechanism is installed on a wheel shaft (13) of a general-purpose human wheelchair, and the wheelchair can conveniently realize long-distance travel: the rocker mechanism is connected to the wheel shaft (13) through a roller type one-way clutch (8). When the rocker arm (6) is pushed forward by hand through the handle (7), the outer ring (1) and the inner ring (2) will squeeze the roller (3) outward, so that the roller type one-way clutch ( 8) Engage with the wheel shaft (13), drive the big wheel (9) to rotate, and drive the wheelchair to move forward; when the rocker arm (6) is pushed backward through the handle (7), the return spring (5) will move to the right Pull the roller (3), the roller type one-way clutch (8) is disengaged, the large wheel (9) continues to rotate by inertia, and the wheelchair continues to move forward. Two front-wheels rotate simultaneously by being fixedly connected in the steering link (17) of front-wheel, realize two front-wheels synchronous steering. The main purpose of the utility model is to allow people with disabilities to operate the rocker mechanism of the wheelchair, which is very convenient and labor-saving, can ensure that the user can drive the wheelchair by himself, and improve the self-care ability of the disabled, and is very suitable for the disabled.
Description
Affiliated technical field
This utility model relates to a kind of wheelchair driving mechanism, is applicable to the trip of the longer distance of the inconvenient crowd of action.
Background technology
Wheelchair is the important tool of rehabilitation, and it is not only the walking-replacing tool of limbs the disabled, the more important thing is to make them carry out physical exercise and participate in social activity by means of wheelchair.Available man-power drives the driving mechanism structure more complicated of wheelchair, operates easyly inadequately, and the wheelchair overall weight is bigger, and manufacturing process and cost requirement are higher, is unfavorable for the trip of lower limb disability and the handicapped longer distance of old people.
Summary of the invention
In order to overcome existing deficiency, this utility model provides a kind of wheelchair driving mechanism, and not only simple and reliable for structure, manufacturing process is simple, and cost is lower, and that operation is very easy is laborsaving.
The technical scheme that its technical problem that solves this utility model adopts is: the wheelchair driving mechanism mainly is made up of rocking arm, roller-type one way clutch and steering mechanism, rocking arm and roller-type one way clutch are linked, adopt two roller-type one way clutches that are connected to link with two axletrees respectively, axletree and big wheel connect firmly, and axletree is connected on wheelchair frame and the seat by bearing.Endplay device links by roller-type one way clutch and axletree, when promoting rocking arm with hands forward by handgrip, outer shroud and internal ring push roller outward, and roller-type one way clutch is engaged with axletree, drive big wheel and rotate forward, drive wheelchair and move forward; When promoting rocking arm with hands backward by handgrip, back-moving spring spurs roller to the right, and roller-type one way clutch is broken away from, and big wheel is rotated further by inertia, and wheelchair continues to move forward; Two front-wheels can rotate the front-wheel steer connecting rod that connects firmly in the front-wheel steering spindle by turning to handgrip, realize that two front-wheels turn to synchronously.Because what driving mechanism used is mono-directional overrun clutch, when driving wheelchair with hand rim, driving mechanism and hand rim mutually noninterfere.
The beneficial effects of the utility model are, the wheelchair driving mechanism is installed on the general manpower wheel chair wheel axle, can allow the inconvenient crowd of action drive operating mechanism by wheelchair, and the trip of longer distance is realized in very convenient labour-saving.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is wheelchair driving mechanism sketch map.
Fig. 2 is wheelchair driving mechanism overall schematic.
Fig. 3 turns to the control sketch map.
1. outer shrouds among the figure, 2. internal ring, 3. roller, 4. ejector pin, 5. back-moving spring, 6. rocking arm, 7. handgrip, 8. roller-type one way clutch, 9. big wheel, 10. hand rim, 11. axle sleeves, 12. bearings, 13. axletree, 14. clutch connecting rods, 15. wheelchair frames and seat, 16. turn to handgrip, 17. front-wheel steer connecting rods.
The specific embodiment
In Fig. 1, roller-type one way clutch is to support with roller (3) between outer shroud (1) and the internal ring (2), and internal ring (2) is equipped with spring (5) and ejector pin (4), produce a lasting thrust by ejector pin (4), roller (3) is pushed outward the contact that has just constituted outer shroud (1), internal ring (2) and roller (3), roller (3) is uninterrupted with contacting of internal ring (2), outer shroud (1), so reaction and transfer of torque power that can be immediately.
When promoting rocking arm (6) with hands forward by handgrip (7), outer shroud (1) pushes roller (3) outward with internal ring (2), and roller-type one way clutch is engaged, and drives big wheel and rotates, and drives wheelchair and moves forward.When pulling back rocking arm (6) with hands by handgrip (7), back-moving spring (5) spurs roller (3) to the right, and roller-type one way clutch is broken away from, and big wheel is rotated further by inertia, and wheelchair continues to move forward.
In Fig. 2, big wheel (9) is welded into integral body with axle sleeve (11), connect with axletree (13) by bearing (12), the flat key of the pillar that rolls left clutch (8) by internal ring (2) connects with axle sleeve (11) on the axletree (13), about two clutches (8) be linked to be integral body by clutch connecting rod (14), when promoting rocking arm forward with hands, about two roller-type one way clutches (8) drive big wheel simultaneously and rotate forward, realize the movement of wheelchair.
Claims (2)
1. wheelchair driving mechanism, mainly formed by rocking arm, roller-type one way clutch and steering mechanism, it is characterized in that, rocking arm (6) and roller-type one way clutch (8) are linked, adopt two roller-type one way clutches that are connected (8) to link with two axletrees (13) respectively, axletree (13) connects firmly with big wheel (9), and axletree (13) is connected on wheelchair frame and the seat (15) by bearing (12).
2. wheelchair driving mechanism according to claim 1 is characterized in that, two front-wheels rotate the front-wheel steer connecting rod (17) that connects firmly in the front-wheel steering spindle by turning to handgrip (16).
