Abstract
The invention relates to wheelchair accessories, in particular to a travelling device capable of performing rocker reciprocating linear motion and converted rotation. When the wheelchair adopts small-diameter wheels or similar mechanical devices, a travelling driving device is provided. The design adopts two rockers which are on the same axial center and have the opposite directions; when the rockers swing towards the same direction, the rockers respectively rotate clockwise and anticlockwise on the axis; and each of the rockers is respectively connected with a ratchet clutch to be fixed on the axis. When the two rockers swing back and forth along one straight line, the two ratchet clutches fixed on the axis can alternately apply power to the axis and continuously drive the wheels of the wheelchair to rotate, so the volume of the wheelchair can be reduced, a user can perform long-distance walking, and pollution of dust to clothes can be avoided.
Description
Technical field
The present invention relates to a kind of Wheel-chair fittings, specifically a kind of rocking bar oscillating rectilinear motion is changed the running gear that rotates.
Background technology
Wheel-chair in the past mainly is the wheel of paying that relies on two road wheels, with the mode driving wheel Wheel-chair walking of arm paddling.There is following defective in this mode: 1, because the spoke diameter of wheel-chair is larger, the volume that dwindles wheel-chair is formed obstacle; 2, when the arm paddling is paid wheel, can't apply continuously power to wheel, be difficult to long distance walking; 3, when the arm paddling is paid wheel, the easy pollution clothes of the dust on the tire and mud.
Summary of the invention
The present invention is intended to design a kind of wheelchair travel driving unit, when wheel-chair adopts minor diameter wheel or similar machinery, provides a kind of travel driving system.The design adopts two on same axle center, the rocking bar of opposite direction; When swinging to same direction, form clockwise and be rotated counterclockwise at axle respectively.Connect separately a pawl clutch, and be fixed on the axle.When two rocking bars swing back and forth along straight line, be fixed on two pawl clutches on the axle like this, just can replace the countershaft power that applies, the rotation of wheel of Continuous Drive wheel-chair.Can not only dwindle the volume of wheel-chair, user is walked at a distance.Also can break away from dust to the pollution of medicated clothing.
Description of drawings
Fig. 1 is the apparatus structure axonometric drawing.
Fig. 2 is apparatus structure running status sketch map.
Fig. 3 is the A-A cutaway view of installation drawing 2.1.
The specific embodiment
The present invention relates to a kind of driving device of wheel-chair walking, as shown in Figure 1, technical characteristics is, ratchet (4) is fixed on the axletree (6) with the internal ring of ratchet (5), the outer shroud of ratchet (4) is connected with lower shake-changing arm (3), the outer shroud of ratchet (5) is connected with upper rocker arm (7), one end of one end of connecting rod (2) and connecting rod (8) and stick (9) is connected on the movable axis, the other end of connecting rod (8) and connecting rod (2) links to each other with lower shake-changing arm (3) with upper rocker arm (7) respectively, and axletree (6) is separately fixed on 2 moving fulcrums of vehicle frame with stick (9).
Stick (9) is its stick other end when pushing away forward, move backward by movable axis (1) drivening rod (8) and connecting rod (2), simultaneously upper rocker arm (7) and lower shake-changing arm (3) under the promotion of connecting rod (8) and connecting rod (2) take axletree (6) as the center of circle, respectively round about rotation, lower shake-changing arm this moment (3) passes through ratchet (4) to axletree (6) transmission of drive force, upper rocker arm (7) zero load.When stick (9) to pulling back, when applying opposite direction strength, drive link (8) and connecting rod (2) drive respectively upper rocker arm (7) and lower shake-changing arm (3) take axletree (6) as the center of circle, rotation is returned round about, and upper rocker arm this moment (7) passes through ratchet (5) to axletree (6) transmission of drive force.Because stick constantly waves, two ratchets have been realized the continuous rotation of wheel alternately to the axletree transferring power.
Claims (2)
1. the outer shroud of ratchet (4) links to each other with lower shake-changing arm (3) and is fixing, the outer shroud of ratchet (5) links to each other with upper rocker arm (7) and is fixing, one end of one end of connecting rod (2) and connecting rod (8) and stick (9) is connected on the movable axis (1), the other end of connecting rod (8) and connecting rod (2) links to each other with lower shake-changing arm (3) with upper rocker arm (7) respectively, and axletree (6) is separately fixed on 2 moving fulcrums of vehicle frame with stick (9).
2. wheel-chair travel driving unit according to claim 1, it is characterized in that: when stick (9) is back and forth done rectilinear motion forwards, backwards, the vertical pole other end, by movable axis (1) and connecting rod (8) and connecting rod (2) drive upper rocker arm (7) and lower shake-changing arm (3) take axletree (6) as the center of circle, respectively round about rotation, continuous conversion direction of rotation, thus drive ratchet (4) and ratchet (5) are alternately to axletree (6) transferring power; Because stick constantly waves, two ratchets with straight reciprocating motion, are converted to continual rotatablely moving alternately to the axletree transferring power.
