Abstract
A hand-cranked assistive bicycle is characterized by comprising rear bicycle wheels, a front bicycle wheel, a seat, handbrakes, rockers, a link set, a bicycle driving shaft and ratchets; the handbrakes are mounted at the front ends of the rockers, the rear ends of the rockers are fixed on the frame, and the middle of the rockers are connected to the upper end of the link set; the link set is composed of four links and forms a diamond-shaped structure, the lower end of the link set is connected to the ratchets, the ratchets are mounted at two ends of the bicycle driving shaft, the left ratchet and the right ratchet are in opposite directions, and the left rocker and the right rocker are lifted up and pressed down alternately to drive the bicycle to move forward. The mechanism combining the rockers, the links and the ratchets is utilized cleverly, a rider can operate more simply, and force can be saved; the left rocker and the right rocker are lifted up and pressed down alternately to drive the bicycle to move forward, so that running smoothness of the bicycle can be improved; the rider can swing up and down the operating rods to drive the bicycle while lying on the backrest, so that riding comfortableness is increased.
Description
Technical field:
The present invention relates to a kind of shaking bicycle of helping the disabled, belong to the field of mechanical technique of helping the disabled.
Background technology:
In recent years, the market development of disabled person's bicycle is rapid, but for the bicycle of the residual personage's design of pin, mostly be in the market the driven by shaking bicycle of 360 degree, it is larger that the driving of this class bicycle needs chaufeur to have an effect, and while having an effect, people's health need lean forward, and for a disabled person, driving for a long time can be comparatively tired out, therefore design a kind of laborsaving and meet the have an effect bicycle of custom of human body and become particularly important.
Summary of the invention:
For designing the bicycle that a kind of disabled person of meeting has an effect and is accustomed to shank disabled person, the technical solution adopted in the present invention is: a kind of shaking bicycle of helping the disabled, it is characterized in that by bicycle rear, front wheel, seat, parking brake, rocking bar, linkage rod group, bicycle axle drive shaft, ratchet forms, parking brake is arranged on rocking bar front end, the rear end of rocking bar is fixed on vehicle frame, the middle part of rocking bar is connected with linkage rod group upper end, linkage rod group is by four linkage rod group diamondwise structures, the lower end of linkage rod group is connected with ratchet, ratchet is arranged on the ratchet opposite direction of bicycle axle drive shaft two ends and left end and right-hand member, on hocketing, left rocking bar and right rocking bar carry, press down and drive bicycle to advance.
The ingenious mechanism that utilizes rocking bar, connecting rod, ratchet to combine of the present invention, make driver's operation simpler, laborsaving, on left rocking bar and right rocking bar hocket, carry, press down and drive bicycle to advance, meet the human body custom of having an effect, increase the ride comfort of bicycle running, chaufeur lies on backrest and can use joystick to swing up and down driving bicycle, has increased driver comfort.
Accompanying drawing explanation
Fig. 1: disabled person's special bicycle schematic diagram
Fig. 2: ratchet schematic diagram
In figure, structure consists of: 1. bicycle rear; 2. seat; 3. parking brake; 4. front wheel; 5. rocking bar; 6. ratchet; 7. connecting rod; 8. bicycle axle drive shaft
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, on chaufeur, carry and press down rocking bar (5), by the effect drive link (7) of lever, and then driving pawl (6), bicycle axle drive shaft (8) is rotated, by chain drive trailing wheel (1), thereby drive bicycle to advance, the ratchet of the right and left (6) installation direction is contrary, and when wherein left side rocking bar (5) presses down, bicycle advances, while carrying on the rocking bar (5) on the right, bicycle advances, and has guaranteed on rocking bar, to carry and press down the power that Shi Junyou drives bicycle to advance, and increases the riding comfort of bicycle.Chaufeur is pinched lower parking brake (3) and can be slowed down or stop.
