Independent double-rear-wheel comfortable long-distance bicycle

Abstract

The invention discloses an independent double-rear-wheel comfortable long-distance bicycle in the field of bicycles, which comprises a frame, a front fork, a rear wheel connecting frame and a front wheel, one side of the frame is fixedly connected with the front fork, the other side of the frame is fixedly connected with a power supporting device, the front wheel is rotatably connected below the front fork. A handle is fixedly connected to the upper portion of the front fork, a power input assembly is fixedly connected to one side wall of the front fork, and a rear wheel supporting frame is fixedly connected to one side of the upper portion of the rear wheel connecting frame. According to the independent double-rear-wheel comfortable long-distance bicycle, the double-rear-wheel independent suspension is adopted, is different from the situation that rear wheels of other tricycles are connected through middle shafts and easy to turn on one side during turning, and is also different from the situation that a common bicycle is provided with a single rear wheel and can only keep balance during movement, thereby having the unique advantages of flexibility and stability, and being suitable for long-distance riding and old people riding.

Description

technical field [0001] The invention relates to the field of bicycles, in particular to a comfortable long-distance bicycle with independent double rear wheels. Background technique [0002] Bicycles and tricycles are the means of transportation that are used more now, but the existing bicycles need to consider the thighs as the axis because the legs are pedaling downward when riding, and the seat design is small and the support is poor. The comfort level is low when traveling, which leads to fatigue easily during long-distance riding, and because it can only maintain balance during exercise, the center of gravity is high, and it is easy to fall, so it is not suitable for the elderly to ride, and some two-wheeled "recumbent bicycles" although lower The center of gravity does not solve the stability problem, and the "lying" riding posture makes the human body's control over the body worse, making it easier to fall and reduce safety. Existing tricycles have poor flexibility d...

[0002] Bicycles and tricycles are the means of transportation that are used more now, but the existing bicycles need to consider the thigh as the axis because the legs are pedaling downward when riding, and the seat design is small and the support is poor. The comfort level is low when traveling, which leads to easy fatigue during long-distance riding, and because it can only maintain balance during exercise, the center of gravity is high, and it is easy to fall, so it is not suitable for the elderly to ride. The center of gravity does not solve the stability problem, and the "lying" riding posture makes the human body's control over the body worse, making it easier to fall, reducing safety

Existing tricycles have poor flexibility due to the central shaft connection between the rear wheels. When turning, because the radius of motion between the inner and outer wheels is different, it is easy to cause one wheel to lift off the ground due to centrifugal force, and it is easy to rollover

At the same time, the power input of existing bicycles and tricycles is circular motion, the power conversion rate is low, and the pedal load is relatively large.
