Hand and foot driven bicycle

Abstract

The invention provides a hand and foot driven bicycle, and belongs to the field of vehicles or bodybuilding apparatus. The bicycle comprises a bicycle frame and a front wheel and a rear wheel which are arranged on the frame. The innovation point is that: an upper limb driving device is arranged on a beam of the frame and is mainly used for shaking a rocker arm by using front-pushing rear-pulling force applied to a bicycle handlebar through a handlebar shaft connected with the bicycle handlebar, realizing the transmission control of gears on a shaft II, a shaft III, a shaft IV and a shaft V through the rocker arm, and outputting power to the rear wheel; meanwhile, rotating force which is applied to the bicycle handlebar and is used for controlling the direction is transmitted to the handlebar shaft connected with the bicycle handlebar, a universal joint coupler, a control connecting rod component and a bicycle front fork in turn, so that the direction of the bicycle is controlled. Compared with the prior art, the hand and foot driven bicycle has the advantages that: the strength of upper limbs can be effectively utilized, the speed of the bicycle can be increased, the comfort degree and interestingness during riding are increased, and the effect of exercising the whole body can be achieved.

Description

(1) Technical field [0001] The invention relates to a vehicle or a body-building apparatus, in particular to a bicycle with dual-wheel drive of hands and feet, which uses the upper limbs to apply auxiliary forward power to the bicycle and simultaneously achieves a good body-building effect. (2) Technical background [0002] The applicant submitted to the State Intellectual Property Office of China on July 30, 2009 an invention patent application for a bicycle with the patent application number 200910017427.1 and the patent name "with auxiliary drive device for upper limbs". After more than a year of experiments, it was found that , the application has the following problems: [0003] 1) The steering booster assembly and the transmission reversing assembly are designed separately and are respectively fixed on the brackets below the crossbeam. The structure is complex and loose, and the power loss is more during the mechanical transmission process, and it is not beautiful. ...

AI Technical Summary

Problems solved by technology

[0003] 1) The steering booster assembly and the transmission reversing assembly are designed separately and fixed on the brackets below the crossbeam respectively. The structure is complex and loose, and the power loss is more during the mechanical transmission process, and it is not beautiful

[0004] 2) The universal joint coupling is easy to be squeezed and damaged during use, resulting in inflexible direction control, and in severe cases, it will be dangerous

[0005] 3) Using 3-stage chain transmission, not only the power loss is large, but also the chain between the pedal sprocket and the rear wheel sprocket is easy to fall off, and the fallen chain is squeezed between the two sprockets on the pedal shaft, making it difficult to repair

[0006] 4) The lock mechanism is complicated to set, the position is unreasonable, the operation is inconvenient, the lock effect is not good and it is not beautiful
