The specific embodiment
Below in conjunction with accompanying drawing this utility model can be elaborated the device that wheelchair expands to rocking chair.
Referring to Fig. 2 and Fig. 3, this utility model can be fixed on the device 2 that wheelchair expands to rocking chair the seat support below of wheelchair 1 through screw bolt and nut.In conjunction with Fig. 1, this utility model device comprises spiral lifting mechanism 4 and hyperbola rocking bar 3.The upper end of spiral lifting mechanism 4 links to each other with the seat support of wheelchair 1, and lower end and hyperbola rocking bar 3 are fixedly linked.Hyperbola rocking bar 3 is located at the left and right sides of spiral lifting mechanism 4.Hyperbola rocking bar 3 is provided with foldable mechanism 16, and this foldable mechanism 16 is a hinge.Hyperbola rocking bar 3 comprises a plurality of bows, links to each other through foldable mechanism 16 between the bow.
During use, open motor power 6,, drive shaft coupling 8 successively and rotate with drive link 17 through just commentaries on classics, the counter-rotating of motor 7.Rotate through drive link 17, drive gear wheel 10 and rotate; Or, drive gear wheel 10 and rotate through manually rotating hand handle 12.Drive the rotation (module of big pinion is identical) of two pinions 11 through gear wheel 10 rotation, and the rotating speed of pinion 11 is several times of gear wheel 10, occurrence is relevant with the gear ratio of pinion greatly.Pinion 11 rotates the rotation that drives threaded screw rod 9, thereby realizes the up-down of spiral lifting mechanism 4.
In the lifting process, it is constant that threaded screw rod 9 and power transmission shaft 17 remain the sustained height difference, with one lifting of same speed.In conjunction with Fig. 4 and Fig. 5, threaded screw rod 9 has two junction points with the diamond structure of lifting structure 13.Junction point of left end (end that threaded screw rod 9 links to each other with front support stand 14) is equivalent to nut; The female thread of locating through external screw thread on the threaded screw rod 9 and junction point (being the fulcrum of lifting structure 13) links to each other; When the rotation of pinion 11 drives threaded screw rod 9 rotations; This end junction point side-to-side movement thereupon, and realize that the angle of diamond structure changes, thus realize.Junction point of right-hand member is being rotationally connected of threaded screw rod 9 and lifting structure 13, and this connection can make threaded screw rod 9 freely rotate, and guarantees the invariant position of junction point at the length direction of threaded screw rod 9 simultaneously.When threaded screw rod 9 rotates, left end junction point meeting side-to-side movement, the junction point of right-hand member keeps original link position, but threaded screw rod 9 can rotate freely.Rotate the rhombus angle that changes lifting structures 13 through threaded screw rod 9 and change, just can realize that elevating movement controlled.
When the hyperbola rocking bar 3 that is connected lifting structure 13 lower ends drops to the four wheels that is lower than common wheelchair; Wheelchair is converted into rocking chair; Can realize the leisure swing function of rocking chair, the wheelchair user is loosened and leisure fully, help physical and mental health more.When directly using as wheelchair, hyperbola rocking bar 3 rises, and fold through foldable mechanism 16 and packs up, and can make implementation wheelchair person free, safe, unrestricted more.
