Lying type precursor two wheel rickshaw

Abstract

The invention relates to the technology of transportation vehicle, in particular to a novel lying type three wheel rickshaw which comprises a frame, a layback seat, a manual drive mechanism, a front wheel and a rear wheel; the frame comprises a front frame and a rear frame, the front end of the front frame is provided with the manual drive mechanism, the middle part thereof is provided with the front wheel and the tail thereof is flexibly connected with the rear frame to form a pair of rotators; the front frame is connected with a rotary handle, and the front wheel is transmitted with the manual drive mechanism by chains; the rear frame is connected with the layback seat, and the tail of the rear frame is mounted with the rear wheel. The layback type seat of the invention has large contact area with human body, adopts layback type hacking during riding, improves riding comfort, and the butt has landing points when hacking is carried out, therefore hacking is more powerful; the invention adopts the front wheel to drive, thus shortening the transmission distance of the chains and causing riding to be more powerful; the front frame and the rear frame are connected by a joint bearing, thus satisfying the requirement of flexible rotation and improving the centring effect of the front wheel; and the whole vehicle has low gravity, thus being beneficial for the stability of riding.

Description

technical field [0001] The invention relates to vehicle technology, in particular to a lying front-drive two-wheeled rickshaw. Background technique [0002] Human-powered bicycles are still used by most residents in our country, mainly as tools for walking and exercising. Especially with the deterioration of environmental pollution worldwide and the soaring international oil prices in recent years, environmentally friendly and energy-saving human-powered bicycles are more and more popular among people. Admired. Most of the currently used human-powered bicycles are mostly two-wheeled structures, but the seats of this type of human-powered bicycles are too small, and they are sandwiched between the two strides, which is not conducive to people's health. The main hazards are genital congestion, prostate Congestion, triggering inflammation, leading to benign prostatic hyperplasia and prostatitis, etc. In addition, when the legs of this bicycle are pedaling, the buttocks have n...

Problems solved by technology

Most of the currently used human-powered bicycles are mostly two-wheeled structures, but the seats of this type of human-powered bicycles are too small, and they are sandwiched between the two strides, which is not conducive to people's health. The main hazards are genital congestion, prostate Congestion, causing inflammation, leading to BPH and prostatitis, etc.

In addition, when the legs of this bicycle are pedaling, the buttocks have no force point, pedaling is laborious, and the center of gravity is high, which is not conducive to riding stability, etc., and because the rear wheel drive is adopted, the chain transmission distance is long, and pedaling is laborious
