Abstract
The utility model relates to a rotating device for hand-driven vehicle. A rotating shaft 4 is fixed to a deflector rod 5 which is connected with a chain 6; the chain 6 is joggled with a flywheel 8 which is fixed to an axle 9; the chains 6 and 2 are matched with an intermediate gear 1; a joystick 2 can be pushed and pulled by hands repeatedly; the flywheel 8 can be rotated by the actions of the rotating shaft 4, the deflector rod 5 and the chain 6; the vehicle can be driven to advance.
Description
The utility model relates to a kind of wheel word of hand-propelled vehicle.
Present car for disabled persons mostly is to drive the flywheel rotation with a hand floral disc by chain, drives front-wheel and promotes that car advances.This structure is because can not design-calculated oversize with the fixing crank of floral disc, faceplate diameter also can not be excessive etc. all multifactor influences, particularly travelling at a distance when driving just seems very painstaking.This vehicle human body both arms and working direction when turning form the angle of a variation, caused person for driving a car's forward lean, upper body is distorted, to adapt to the adjustment of this angle, make the person for driving a car pay more work, also do not conform to the requirement of disabled person's health.Also have a kind of car for disabled persons to drive trailing wheel to rotate handwheel by turbine worm vehicle is advanced, though this car has solved the problem that human body will adapt to the turning angle, the speed of a motor vehicle obviously slows down, and the strength that the person for driving a car pays is bigger.
The purpose of this utility model is exactly the deficiency at the above-mentioned background technology, and provides a kind of rational in infrastructure, and is firmly less, the wheel word of the hand-propelled vehicle of can powered vehicle advancing by the push-and-pull joystick.
The technical solution that realizes above-mentioned purpose is: fix one pair of flywheel of installing in the same way on axletree, be connected with chain with the driving lever termination that has in the rotating shaft of joystick bonded assembly, wherein chain is connected with attachment point by extension spring behind flywheel, and another root chain is connected with attachment point by extension spring after then centering on idle wheel and flywheel respectively.The axle sleeve of rotating shaft and all be fixed on the vehicle body with extension spring bonded assembly attachment point.
Accompanying drawing is a structural representation of the present utility model.
Now in conjunction with the accompanying drawings the utility model is done a description.
As shown in drawings, with the fixing axletree 9 of wheel 7 on a pair of flywheel 8.1,8.2 is installed in the same way, the gear on this flywheel 8.1,8.2 meshes with chain 6.1,6.2.One end of rotating shaft 4 is connected with joystick 2, also is fixed with two driving levers 5 in the rotating shaft 4, and each flexibly connects an end of this driving lever 5 with an end of chain 6.1,6.2.Wherein chain 6.1 is connected with attachment point 12 by extension spring 11 around flywheel 8.1 backs; And 6.2 on chain is connected with attachment point 12 by extension spring 11 behind idle wheel 1 and flywheel 8.2.All be rigidly connected with rotating shaft 4 and axletree 9 bonded assembly axle sleeves 3 and attachment point 12 with vehicle body.The damper brake 10 that similar three-wheel vehicle is used also is installed on axletree 9, and this damper brake 10 can be by pulling or pin is treaded existing braking.The flywheel that said flywheel 8.1,8.2 is used for ordinary bicycle.
When staff back and forth during reciprocating sliding joystick 2,4 drive driving levers 5 of rotating shaft move repeatedly, and drive flywheels 8.1,8.2 by chain 6.1,6.2 and rotates (wherein a chain 6.2 is to move around flywheel 8.2 again after walking around idle wheel 1) repeatedly.Because the characteristic of flywheel and the effect that two flywheels 8.1,8.2 and extension spring 11 are installed, when the corresponding flywheel 8.1 of a chain 6.1 drivings rotates, its another root chain 6.2 is walked around idle wheel 1 and has been changed sense of motion, thereby the relative axletree 9 of external toothing that drives corresponding flywheel 8.2 is done the opposite sense motion.Alternating movement so so repeatedly then can make vehicle advance forward continuously, and when vehicle need suspend rest when going up a slope, need only decontrol joystick and get final product, because the effect of flywheel, vehicle just can oppositely not slide, and can stop automatically.
According to person for driving a car's health and custom, joystick can be installed in an end of rotating shaft arbitrarily, to adapt to the human needs of driving.
The utility model is simple and reasonable, can drive vehicle body by the reciprocating sliding joystick and advance, and can stop automatically during back skating, is fit to very much the sound disabled person of upper limbs or the elderly and uses as walking-replacing tool.
Claims (3)
