Abstract

The utility model relates to a human body potential energy boosting bicycle, comprising a rear wheel drive bicycle. The human body potential energy boosting bicycle is characterized in that springs are arranged under a bicycle seat; the spring is plugged on a bicycle frame; rack bars are arranged under the bicycle seat; springs are arranged on the rack bar; a ratchet wheel which is arranged on the bicycle frame is in mesh with the rack bar; a chain wheel is arranged on the same shaft of the ratchet wheel; the chain wheel is connected with the ratchet wheel which is arranged on the rear shaft via a chain. The utility model utilizes the consumed natural energy to boost the bicycle, and no electric energy nor fuel is needed to consume; not only the work efficiency of the bicycle can be raised but also can achieve labor saving and high speed, and generates no pollution to the natural environment simultaneously.

Description

Human body potential energy morpet

The utility model is a kind of vehicle, particularly a kind of morpet.

Bicycle is the main vehicle in contemporary China, it is a kind of rickshaw, and for reducing the expenditure of people's muscle power in traveling process, the someone has developed morpet, the power-assisted of existing various morpets is by a fractional motor being installed on car body, being divided into fuel oil and power consumption two classes.Though this boosted vehicle can reduce the expenditure of people's muscle power, has wasted the energy, environment is produced pollute simultaneously.

The purpose of this utility model provides a kind of later-model boosted vehicle, and it can overcome existing shortcoming in the prior art, not only can be laborsaving, and the source, free from environmental pollution of not consuming energy.

The purpose of this utility model is achieved in that it comprises a back-wheel drive bicycle, it is characterized in that under bike saddle, spring being housed, be inserted on the vehicle frame, tooth bar is installed below the vehicle seat, spring is housed on the tooth bar, what be meshed with tooth bar is mounted in ratchet on the vehicle frame, with coaxial ratchet a sprocket wheel is arranged, and this sprocket wheel links by chain with the ratchet that is installed on the rear axle.

For tooth bar and ratchet can be thrown off where necessary, a power-transfer clutch is installed under vehicle seat, promptly be suppressed with decorative pattern on clamp and the contacted plane of tooth bar that tooth bar is installed, to increase the friction coefficient between them, when needs broke away from, the plate carry-over bar was thrown off it and ratchet, because the friction force between clamp and the tooth bar is greater than the spring force on the tooth bar, so tooth bar can keep disengaged position.

For improving the reinforcement coefficient, can also increase the one-level chain gear, improve converter speed ratio, to improve reinforcement efficient.

The vibratory force that the utility model produces by the ground-surface out-of-flat, pass to trailing wheel by tooth bar by sprocket wheel, the effect that bicycle is reached advance automatically, utilized used up in the past natural energy, and need not consume any electric energy or fuel, so not only can improve the work efficiency of bicycle, accomplish laborsavingly, quick, simultaneously do not produce any pollution for natural environment.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.

Fig. 1 is a structure side view of the present utility model.

Fig. 2 is that A among Fig. 1 is to view.

As seen from the figure, 1 for the vehicle frame of rear drive bicycle, be fitted with vehicle seat 3 above the vehicle frame, at the plug-in mounting position spring 2 is housed, to improve the elasticity of vehicle seat,, the nut 13 and the jackscrew 14 of regulating spring tension force is housed below spring owing to people's body weight difference, jackscrew is stuck on the step same under the nut, just can obtains different spring tensions.Under the seat clamp 4 is arranged, tooth bar 6 is contained in the centre of clamp, use bolt, spring 5 is housed on the tooth bar, to keep tooth bar to have outside tension force, be meshed with ratchet 8, with coaxial ratchet be a sprocket wheel 7, sprocket wheel 7 links by chain 9 and minor sprocket 10 in the pair of sprocket that is installed on the vehicle frame, bull wheel 11 links with the ratchet 12 that is installed on the rear axle, rolling has straight burr on clamp 4 and the tooth bar 6 contacted A surfaces, so that it has the elastic force that enough friction force can overcome spring 2, tooth bar can be thrown off with ratchet.

Claims

1, human body potential energy morpet, it comprises a back-wheel drive bicycle, it is characterized in that under bike saddle, spring being housed, be inserted on the vehicle frame, tooth bar is installed below the vehicle seat, spring is housed on the tooth bar, what be meshed with tooth bar is mounted in ratchet on the vehicle frame, with coaxial ratchet a sprocket wheel is arranged, this sprocket wheel links by chain with the ratchet that is installed on the rear axle.

2, according to the said bicycle of claim 1, it is characterized in that tooth bar is fixed under the vehicle seat by a clamp, the surperficial rolling that clamp contacts with tooth bar has decorative pattern.
