Description

A kind of morpet

The utility model relates to a kind of morpet.

Existing power-assisted two-wheeled, tricycle have electric boosted, there is spark ignition engine power-assisted, also have adopt the potential energy that the unnecessary kinetic energy in the downhill running process is converted into spring to accumulate then to discharge power-assisted, the potential energy that also has employing that the bumping kinetic energy in the process by bike is converted into spring accumulate then discharge power-assisted.In the above several types, though preceding two kinds of power-assisted effects are better, cost height, maintenance are many, but also will consume the energy, contaminated environment, are subjected to the restriction of masses' economic condition or certain rules, have certain difficulty in promoting the use of.The back all needs corresponding transformation mechanism of supporting assembling and control mechanism for two types, the structure more complicated, and cost is than higher, and it uses the restriction that is subjected to certain landform again, and range of use has certain limitation, generally promotes also being not easy.

The purpose of this utility model is to provide a kind of morpet, and this bicycle should have simpler structure, cheaper cost, and accumulation of energy at any time simultaneously arbitrarily discharges power-assisted.

For achieving the above object, this technical scheme is to have adopted a kind of morpet, one Voluted spring energy accumulated device is installed on cycle frame, transmission cooperates and the ratchet device that transmission cooperates is installed between the output shaft of this energy storage equipment and the bicycle middle shaft, and the ratchet device engage a gear was to spring energy-storage when this cooperation can make the pedal back-pedal.

Described Voluted spring energy accumulated device is installed on the main car frame of axis top, and ratchet device is installed on the axis.

The output shaft of described energy storage equipment and ratchet device can be assemblied in the left side of main car frame respectively, also can be assemblied in the right side of main car frame respectively.

Be equipped with a fluted disc on the output shaft of described energy storage equipment, the diameter of this fluted disc is greater than the diameter of ratchet, and chain is connected between fluted disc and the ratchet device.

Right-hand member head at the energy storage equipment output shaft radially fixedly mounts a ratchet dish, this ratchet dish and one rotates the non-return be assemblied on the energy storage equipment housing right flank and comes directly towards mutual retaining and cooperate, one side of the afterbody of non-return top is connected with retracing spring, another side links to each other with an end of the heart yearn of a control brake cable, and the other end of the heart yearn of control brake cable links to each other with the control sneek that the right handlebar of bicycle assembles down.

Because the ratchet device that is equipped with on the axis of the present utility model, Voluted spring energy accumulated device is installed on the main car frame above the axis, when not accumulation of energy of spring pedal is just being pedaled, axis and axis canine tooth wheel disc just change, the utility model drives operation as the ordinary bicycle manpower, along sliding, its driving chain is motionless between the inside and outside cover of ratchet device, and energy-storaging spring is in free relaxed state.When bicycle is about to climbing and will need power-assisted or think that power-assisted slides, the user only needs the pedal back-pedal, ratchet device can carry out accumulation of energy to spring by engage a gear drive chain, like this, bicycle has just been finished the operation of power-assisted accumulation of energy in the advancing slip process of freedom, when climbing the cyclist with regard to available less strength along pedaling pedal, easily advance under the twisting force releasing forward of energy storage equipment, when thinking that the level land power-assisted slides, need not exert oneself, only along with rotating, pedal gets final product with both feet.In that release can power-assisted in the process, the cyclist also needs according to circumstances pedal pedal at any time, allows the bicycle art skating, and arbitrarily release can power-assisted in control.In addition since an end of energy storage equipment central rotating shaft assembled can control setup by releasing of constituting of ratchet dish and non-return top, the cyclist also can according to the length on sloping road and need power-assisted particular case arbitrarily control accumulation of energy what and release can what.As can be seen, the utlity model has advantage simple in structure, reliable operation, maintenance less, cost is low, popularize easily.The utility model can arbitrarily be controlled accumulation of energy and release energy, and does not change the original function and the original structure of bicycle, both has been convenient to producer and has implemented to produce, and also is convenient to the masses' daily use.Moreover total man's power of the present utility model designs not energy loss, and is free from environmental pollution, not only favourable, also favourable to improving environment to reducing use cost.

Below in conjunction with accompanying drawing the utility model is further explained the explanation:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the accumulation of energy of energy storage equipment one side assembling among Fig. 1 and the unidirectional transmission of releasing energy cooperate scheme drawing;

Fig. 3 is the structural representation of releasing the energy control mechanism of energy storage equipment opposite side assembling among Fig. 1;

Fig. 4 is the structural representation of Voluted spring energy accumulated device among Fig. 1.

Embodiment such as Fig. 1, Fig. 2, shown in Figure 4, among Fig. 1, the middle part of main car frame 1 is equipped with Voluted spring energy accumulated device, and this device is made up of central rotating shaft 2, volute spring 3 and shell 4.Volute spring is wrapped on the central rotating shaft, and its inner termination is fixed on the axial plane of central rotating shaft, and its outer end is fixed on the housing of shell 4.About 6 meters of the roll bending length of volute spring, width 40 millimeter, thickness 1.5 millimeter.The volute spring central rotating shaft of present embodiment stretches out left, and fixedly is equipped with fluted disc 5 on the termination stretching out.On pedaling the axial plane of the axis 6 that turns in the fixed head, the left foot in bicycle left side fixedly is equipped with ratchet device 7.The ratchet diameter of ratchet device 7 is in transmission connection with chain 8 between the two less than the diameter (ratio between two was generally got 1: 3) of fluted disc 5.When the pedal back-pedal, make ratchet device 7 engage a gears drive chain 8 and fluted disc 5 make volute spring 3 accumulation of energys by axis 6.When step is pedaled when just pedaling, if in the volute spring 3 accumulation of energy is arranged, volute spring will drive chain and ratchet device rotates, and drives axis by ratchet device again and rotates bicycle is advanced, and as if no accumulation of energy, ratchet device will only slide, and bicycle is only driven by manpower.

Embodiment 2 is with the difference of embodiment 1: a, ratchet device 7 are assemblied on the axis 6 of big chain plate inboard, bicycle right side; B, central rotating shaft 2 stretch out to the right, and fluted disc 5 fixedly is assemblied on the termination that central rotating shaft 2 stretches out to the right; C, chain 8 are in transmission connection fluted disc 5 and ratchet device 7 together on the bicycle right side.Owing to only be obviously corresponding change the on the rigging position, therefore in this no longer accompanying drawing signal.The using method of present embodiment does not describe in detail at this with embodiment 1 yet.

Embodiment 3 is as Fig. 1, Fig. 2, shown in Figure 3.Present embodiment and embodiment 1 structure are basic identical, difference is at the fixing assembling one of the right-hand member head of the central rotating shaft 2 of Voluted spring energy accumulated device ratchet dish 11 radially, on the right flank of the shell 4 of energy storage equipment, rotate assembling one non-return top 13, non-return top 13 cooperates with the ratchet non-return of ratchet dish, one side of the afterbody of non-return top connects a retracing spring 12, another side connects an end of the heart yearn of a brake cable 9, and the other end of the heart yearn of this brake cable is connected last control sneek 10 with bicycle is right.This embodiment central rotating shaft right-hand member head side install additional release can control mechanism after, can reach the gradation accumulation of energy, the effect that gradation discharges.Level road slide or downhill running in, but the back-pedal pedal carries out accumulation of energy at any time, accumulation of energy is blocked at any time by non-return top 13 again, can not freely emit.When needs, can pinch the control sneek 10 under the right bicycle handle bar, the heart yearn pulling non-return top by brake cable 9 emits the potential energy in the energy storage equipment at any time, thereby plays the power-assisted effect.When not needing power-assisted, unclamp control sneek 10, pin the ratchet dish again non-return top 13, stops accumulation of energy to be emitted.

It is to be noted; the embodiment that more than exemplifies is two kinds of embodiments of fairly simple practicality; in addition the variation that some are installed; for example Voluted spring energy accumulated device is installed in rear bicycle frame; perhaps transfer ratchet device is installed on the central rotating shaft of Voluted spring energy accumulated device; perhaps allow Voluted spring energy accumulated device be in transmission connection with bicycle rear axle earlier and link with bicycle middle shaft then, should all belong to the row of the utility model protection by chain.
