Abstract
The utility model relates to the improvement for an existing bicycle; a human body deadweight booster composed of a guide sleeve, a sliding bar, a support frame, a connecting bar, a compression spring, a crank, a chain wheel, a chain wheel shaft, a tension wheel, a chain, a flywheel, etc. is added The utility model is characterized in that the energy generated by the deadweight of a riding person because of bumpiness is converted to auxiliary power boosting the bicycle advance during riding, so that the effects of saving labour and easily accelerating are achieved. The utility model provides left and right placing schemes for selecting and provides the production scheme for new bicycles and the reforming scheme of old bicycle.
Description
The utility model relates to a kind of power-assisted bicycle of body weight that utilizes, and it comprises vehicle frame, wheel, handlebar, work-saving device etc.The prior art bicycle has only one to pedal capable propulsion source with both feet.The utility model has overcome the deficiency of prior art bicycle, increase by a cover body weight work-saving device, the energy that (it is violent to jolt during Uneven road) produced when the cyclist jolted onboard when just sitting saddle and in riding with cyclist's body weight, change the auxiliary power that propelled bicycles advances, quickens into, to reach purpose laborsaving by bike, easy acceleration.
The utility model design-calculated body weight work-saving device, simple structure, compact conformation, easily processing and manufacturing.
Body weight morpet structure sees accompanying drawing 1 for details.
The neutral beam of body weight morpet vehicle frame be about two parallel steel tube, and as the orienting sleeve of work-saving device.
Work-saving device is made up of orienting sleeve (1), sliding bar (2), support (3), connecting rod (4), compression spring (5), crank (6), sprocket wheel (7), sprocket shaft (8), tension wheel (9), chain (10), flywheel (11) etc.
Orienting sleeve (1) is made up of interior two parallel steel tube that compression spring (5) is housed, and wherein a bottom has slotted hole.Sliding bar (2) also is made up of two parallel sliding bars, and the upper end connects firmly with a flat board, and saddle is installed on it.Sliding bar and orienting sleeve fit in sliding guide mechanism, right side or left side (deciding) sliding bar bottom on selected work-saving device installation site, and promptly orienting sleeve leaves the slotted hole place and connects with support (3), plays power transmission and position-limiting action.Crank (6) connects firmly with sprocket wheel (7), and sprocket shaft (8) is installed in the chain stays front portion.Support (3) connects with connecting rod (4) with crank (6), and sprocket wheel (7) links to each other with flywheel (11) on being contained in backshaft skin by chain (10).Tension wheel (9) is contained in the chain stay middle part with the chain homonymy.
Function of the present utility model has:
One, when the cyclist just sits saddle, because the gravity of human body makes sliding bar (2) and support (3) move along orienting sleeve (1) downwards by saddle, reach crank (6) through connecting rod (4), make sprocket wheel (7), drive flywheel (11) by chain (10) and rotate around sprocket shaft (8) rotation.This moment, the cyclist did not use the pedal car as yet, and bicycle just can advance.
The gravity of (it is more violent to jolt during Uneven road) human body will be exerted pressure continuously to saddle when two, the people jolted onboard in riding, and work-saving device promptly works and makes the utility model bicycle than prior art bicycle labor saving, easily acceleration.
Three, when for a long time by bike, when the cyclist felt that two legs are tired, a very important person is porpoising up and down on saddle, and work-saving device will work, and bicycle is moved on, and can make cyclist's leg muscle intermittently.
Four, set up under the saddle by orienting sleeve (1), sliding bar (2), compression spring (5), the bitubular spring vibration damper formed, improved damping effect.Therefore, ride that the utility model bicycle is more comfortable than prior art bicycle, indefatigability.
Maximum characteristics of the present utility model are cyclist's body weight as an auxiliary power source, and propelled bicycles advances under given conditions.
It is selective that work-saving device can be placed in the right side or the left side of vehicle frame.
When work-saving device was placed in the vehicle frame right side, the flywheel that is used for work-saving device was the same with existing freewheel, can and adorn two existing flywheels (wherein inboard flywheel is used for work-saving device); Also can be processed into the outer round trip flight wheel of adorning two Case of fly-wheel of cover in.But it is longer that rear axle leather jacket flywheel one side will be processed, and is as the criterion can hold two flywheels.This kind compact conformation, processing easily.
The flywheel that is used for work-saving device when work-saving device is placed in the vehicle frame left side will be processed into the left-handed flywheel opposite with existing freewheel, and backshaft skin can be with having common backshaft skin now, and left end is processed into the minus thread that cooperates with left-handed flywheel and gets final product.It is convenient that this kind structure is installed, repaired.
The utility model also can be implemented by accompanying drawing 2.Fixedly chain (13) stretches two ends and is fixed on the chain frame (12), its chain stretch direction will with orienting sleeve (1) axis parallel, hinge wheel (or fan-shaped sprocket sheet) (14) and the riveted joint of sprocket wheel (7) concentric, hinge wheel and fixing chain engages.Remainder is with accompanying drawing 1.
The utility model can also can improve old bike as new car production, only need form one group of pilot sleeve with former neutral beam by a face down bonding one steel pipe of selected arrangement scheme at the neutral beam of former vehicle frame during improvement, gets final product with addition of worker's rod member that slides again.Remaining parts is manufactured by new car.
Claims (3)
1, a kind of power-assisted bicycle of body weight that utilizes, it comprises vehicle frame, wheel, handlebar, work-saving device etc.It is characterized in that: orienting sleeve (1) is made up of interior two parallel steel tube that compression spring (5) is housed, and wherein all has slotted hole under one.Sliding bar (2) also is made up of two parallel sliding bars, and the upper end connects firmly with a flat board, and saddle is installed on it.Sliding bar and orienting sleeve fit in sliding guide mechanism, a sliding bar bottom, and promptly orienting sleeve leaves the slotted hole place and connects with support (3), plays power transmission and position-limiting action.Crank (6) connects firmly with sprocket wheel (7), and sprocket shaft (8) is installed in the chain stays front portion.Support (3) connects with connecting rod (4) with crank (6), and sprocket wheel (7) links to each other with flywheel (11) on being contained in backshaft skin by chain (10).Tension wheel (9) is contained in the chain stay middle part with the chain homonymy.
