Rocker reciprocating type variable-speed bicycle additionally with neutral gear

Abstract

The invention relates to a rocker reciprocating type variable-speed bicycle additionally with a neutral gear. The rocker reciprocating type variable-speed bicycle additionally with the neutral gear comprises a frame; a return rocker swing-angle control speed change device used for controlling a pedal rocker to reciprocate up and down and controlling the swing angel of a return rocker to change is arranged on the middle upper portion of the frame and comprises a mounting frame; and a transversely-arranged return rocker locating groove and a longitudinally-arranged return rocker lifting groove are formed in the mounting frame, the return rocker is mounted in the return rocker locating groove and the return rocker lifting groove through a return rocker shaft, and the speed of the bicycle is adjusted by regulating the swing angle. The rocker reciprocating type variable-speed bicycle additionally with the neutral gear has a better comfort degree and a better labor-saving effect, perfect use functions and higher use safety, and has the characteristics of being simple in structure, convenient to operate, easy to manufacture, wide in application range, and the like.

Description

technical field [0001] The invention belongs to the technical field of bicycles, and relates to a bicycle with a reciprocating rocker and a neutral gear. Background technique [0002] Existing pedal bicycle product, the conversion transmission mechanism of its power is to be made up of the central axis of bicycle, left and right pedal rocking arms, large chain disc transmission chain unidirectional transmission sprocket wheel, rear axle etc. Its power is generated by the continuous 360° circular rotation of the left and right rocker arms and the large chain plate relying on the continuous up and down circular motion of the human body's legs. And through the transmission chain, the power is transmitted to the one-way transmission sprocket, the chain shaft and the wheels so that the bicycle can roll forward. The size of its power depends on the size of the force exerted by the human legs on the rocker arm, and the length of its rocker arm is also one of the main factors. How...

Problems solved by technology

The power of the human body is also difficult to give full play to, which ultimately results in poor labor-saving effect of this type of pedal bicycle, heavy operation, and high energy consumption.

For this reason, the applicant applied for a patent on August 10, 2015. The patent application number is 2015104847045 for a rocker reciprocating rubbing bicycle, but there are defects in use, mainly in the original application. The lack of a speed change function reduces the riding comfort and labor-saving effect of the bicycle. Secondly, this type of bicycle does not have a neutral design. When the bicycle needs to move backward when it is parked to avoid pedestrians or objects, it will be restricted by the limit of the rocker and cannot move by itself. , causing inconvenient use. In addition, the length of the pedal rocker is long and the pedal is set forward.
