Example Embodiment

[0027] The following are specific embodiments of the present invention combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0028] Such as figure 1 , figure 2 with image 3 As shown, the labor-saving bicycle includes a frame 2, a front wheel connected to the front of the frame 2, and a rear wheel connected to the rear of the frame 2, where the rear wheel is generally used as the driving wheel 1. The frame 2 between the front wheel and the rear wheel is connected with a vertically arranged crankshaft disc 3 in the shape of a disc, and the outer side of the crankshaft disc 3 is connected with a pedal for the user to step on and drive the crankshaft disc 3 to rotate in the circumferential direction. 4.

[0029] The labor-saving bicycle also includes a transmission rod 5 in the shape of a long rod. The eccentric position of the side of the crankshaft disc 3 also ha...

Abstract

The invention provides a labor-saving bicycle, and belongs to the technical field of bicycles. The labor-saving bicycle solves the problem that the existing bicycle has poor structural stability. The labor-saving bicycle comprises a frame and a driving wheel, wherein crank discs are connected to two sides of the frame respectively; pedals are connected to the side parts of the crank discs; the labor-saving bicycle further comprises a driving wheel rotationally fixed on the frame and two transmission rods which are arranged on two sides of the frame respectively and are in a long rod shape; one ends of the two transmission rods are connected with the driving wheel; the other ends of the two transmission rods are movably connected to the eccentric positions of two crank discs respectively; the two transmission rods can alternately swing back and forth around the driving wheel when the crank discs rotate in the circumferential direction; a one-way transmission structure is arranged between the driving wheel and the two transmission rods; and the rotation of the driving wheel can be driven by a chain or a belt to rotate the driving wheel. The labor-saving bicycle has the advantage of good stability of the transmission structure.

Description

technical field [0001] The invention belongs to the technical field of bicycles and relates to a labor-saving bicycle. Background technique [0002] With the continuous increase of the number of automobiles, the pollution caused by the tail gas emitted by automobiles is also becoming more and more serious. Simultaneously, the parking space is also increasingly tight, and it is difficult to meet the increasing demand of automobiles. Because of its economy, convenience, flexibility, pollution-free and docking freedom, bicycles begin to receive people's attention constantly, and bicycles will inevitably become an indispensable means of transportation in people's daily life. Yet present bicycle only cooperates simple sprocket chain structure to drive wheel forward by traditional foot pedal, once run into the road condition that needs bigger driving force such as steep slope, will cause bigger inconvenience to people's travel. [0003] For this reason, people have designed a ki...
