Abstract

The utility model relates to a spiral power spring boosting bicycle which can tighten a spiral power spring in a spiral power spring box by stringing while riding in the process of normal running. Energy stored by the tightened spiral power spring can pull up a draw rod spiral power spring by using a control wheel, so that the energy can be released to drive the spiral power spring box to rotate, a one-way driving wheel which is arranged on the spiral power spring box can drive a big chain wheel to rotate, the rotation can be transmitted to a back wheel through a chain, and accordingly, the purposes of speeding up and boosting can be obtained.

Description

The spiral spring boosting bicycle

The utility model relates to a kind of bicycle transformation, utilizes clockwork spring to tighten the back energy storage specifically, drives hinge wheel by its force of explosion when discharging, and chain and rear axle reach the purpose of the bicycle power-assisted speedup in advancing.

Though bicycle has its performance of many improvement that raising is also arranged at present, but still require great effort very much, as accelerating an axle bicycle, derailleur etc. will improve just effort of the speed of a motor vehicle.

With regard to existing energy-saving electric bicycle, the HM Hydraulic Motor bicycle is the disclosed notification number CN2030170U of Patent Office of the People's Republic of China, and multiple energy storage bicycle etc. still needs battery, motor, HM Hydraulic Motor, need many axles in the transmission device again, multiple gear and part, complex structure, the cost height, contaminated environment is unfavorable for implementing the improvement of still needing.

The purpose of this utility model is exactly the deficiency at above-mentioned car, utilizes clockwork spring and two flywheels, a control wheel, and an axis simple structure is designed to save manpower, and is with low cost, the free of contamination spiral spring boosting bicycle of being convenient to keep in repair durable in use.

The purpose of this utility model is achieved in that

To reequip parts and be connected, and pass repacking parts shell two end cap bearing hole and adorn an axis, axis two ends dress pedal with bicycle rack.The barrel that bearing is housed is contained on the axis, and axis, barrel are respectively adorned a flywheel, clamp hinge wheel between two flywheels.On barrel, install a control wheel, this control wheel be contained in shell on and the control pull rod of passing shell be meshed, and spur control pull rod by brake lever on the handlebar.Dress clockwork spring in the barrel, clockwork spring one end hangs on the barrel inwall, and an end hangs on the bar core that installs on the axis.When control wheel and control pull rod did not mesh the axis rotation, flywheel drove hinge wheel on the axis, and chain and rear axle rotate, flywheel idle running on the barrel.When the control wheel was meshed the axis rotation with control pull rod, the bar core winded up clockwork spring on the axis, after the control pull rod pull-up, flywheel on the barrel drives hinge wheel because of the force of explosion that the clockwork spring that tightens discharges, chain and rear axle rotate, and flywheel dallies on the axis, reach the purpose of this utility model.

For reaching the purpose of this utility model, the concrete structure characteristics are described with reference to the accompanying drawings as follows:

Fig. 1 is repacking parts and the joining scheme drawing of bicycle rack.

The scheme drawing that Fig. 2 cuts open for repacking components A-A.

Repacking parts and vehicle frame link up both with screw.Repacking parts concrete structure is the bearing hole that axis 8 passes the shell two end cap, carries out axial location with collar, except that adorning former bicycle pedal, also adorns anti-reverse runner 9 at the axis two ends on it, bar core, barrel 1 and flywheel 5.And anti-reverse runner 9, the bar core, flywheel 5 is fixed with axis 8 usefulness keys, barrel 1 left side endoporus is adorned 203 bearings and is bearing on the axis 8, dress clockwork spring 2 in the big endoporus in barrel 1 left side, one end of clockwork spring 2 hangs on the bar core, and an end hangs on the inwall of barrel 1, adorns a control wheel 3 and one flywheel 5 with key on barrel 1 right side small end external diameter.Flywheel 5 on flywheel on the axis 85 and barrel 1 fastens a hinge wheel 6 between the two.Anti-reverse runner 9 is contained in the shell left end cap, and ratchet also is packed in the shell left end cap, and is meshed with anti-reverse runner 9.Control pull rod 4 on the control wheel 3 is contained on the shell, and passes control wheel 3 engagements on shell and the barrel 1, the brake lever pulling on the available handlebar.When control wheel 3 and control pull rod 4 did not mesh axis 8 rotations, the flywheel 5 that is contained on the axis 8 drove hinge wheels 6, and chain 7 and rear axle rotate, and was contained in flywheel 5 idle running on the going barrel 1.When control wheel 3 rotates with control pull rod 4 engagement axis 8, bar core on the axis 8 winds up clockwork spring 2, when pull-up control pull rod 4, flywheel on the barrel 1 drives hinge wheel 6 because of the force of explosion that the clockwork spring that tightens discharges, chain 7 and rear axle rotate, flywheel idle running on the axis 8, the bicycle power-assisted speedup in advancing.Anti-reverse runner 9 can not reverse because of clockwork spring tightens the back bounce with the engagement axis 8 of ratchet.

The advantage of spiral power spring boosting bicycle:

1, because above structure adopts standardized element more, comprise two flywheels, bearing, ratchet,

Ratchet, control wheel is so the simple and easy cost of this structure processing and manufacturing is low, safe and reliable, anti-

With, renewal part is easy to maintenance.

2, again because auxiliary power adopts clockwork spring, thus fuel-efficient, power saving, pollution-free.

3, again owing to the utility model novel and reasonable structure, two flywheels clamp hinge wheel, cause

Make this car as required speed of a motor vehicle speed wind up at any time and put string, more outstanding is that car is at height

It is more laborsaving to wind up when speed is travelled.

4, behind the pull bar 4 of pull-up control wheel 3, because going barrel and clockwork spring quality are bigger, its

Effect of inertia is also big than ordinary bicycle, so car is lighter laborsaving when sliding.

Number in the figure: 1 going barrel, 2 clockwork springs, 3 control wheels, 4 control pull bars, 5 flywheels, 6 hinge wheels, 7 Chain, 8 axis, 9 anti-reverse runners.

Claims (1)
