Air bag damping wheelbarrow

Abstract

The invention discloses an air bag damping wheelbarrow which comprises a motor wheel assembly, a wheel carrier provided with pedals are at the two sides respectively; a motor wheel assemblyin relativesliding connection with the wheel carrier through a guide device; and a damping air bag which is arranged between the wheel carrier and the motor wheel assembly ,and bears damping of relative movement between the wheel carrier and the motor wheel assembly. According to the wheelbarrow, the damping air bag is adopted for damping, the wheelbarrow has the advantages of being low in weight, high in comfortableness, resistant to fatigue, long in service life and the like, the stroke ratio is large, and a good damping effect can be achieved in a limited space; and meanwhile, the rigidity of the damping air bag is changed along with the vibration load capacity, so that elastic grounding can be avoided, and rigid collision between the wheel carrier and the motor wheel assembly is prevented.

Description

technical field [0001] The invention relates to the technical field of electric unicycles, in particular to an airbag shock-absorbing unicycle. Background technique [0002] As a new type of walking, entertainment and sports equipment, the unicycle has the advantages of fashion and lightness. [0003] Most of the unicycles currently on the market use attitude sensors and accelerometers to control the operation of the unicycle, so the riding posture of the human body has a significant impact on the operation of the unicycle. In a general unicycle, since the car itself does not have a shock absorbing device, all the shock absorbers only rely on the single effect of rubber pneumatic tires, which makes it difficult to control the handling and speed of off-road, obstacle-crossing, and bumpy roads, and the sports comfort is very poor. People are often knocked off the pedals, or because of the displacement of the feet on the pedals at the moment of flight, the balance state after ...

AI Technical Summary

Problems solved by technology

In a general unicycle, since the car itself does not have a shock absorbing device, all the shock absorbers only rely on the single effect of rubber pneumatic tires, which makes it difficult to control the handling and speed of off-road, obstacle-crossing, and bumpy roads, and the sports comfort is very poor. People are often knocked off the pedals, or their feet are shifted on the pedals at the moment of flight, resulting in unstable balance after landing and falling down

[0004] Although there are also some unicycles with shock absorption function, hydraulic shock absorbers are used for shock absorption. Since the hydraulic shock absorber has a piston rod and cylinder body structure, the maximum compression stroke during shock absorption is less than 50% of its overall length. The shock absorption stroke ratio is small and the weight is heavy. When driving in complex road conditions, it is easy to run out of shock absorption stroke and produce elastic bottoming
