Problems solved by technology

When the bicycle of the present invention is in use, if the user encounters an uphill road or a bad road condition, the user switches the clutch structure to the first state through the transmission device, and the pedals can quickly transition from the state where it is difficult to exert force to the state where it is easy to exert force. When the pedal is close to the plumb line, that is to say, when the pedal is generally distributed upwards and downwards, the clutch structure is switched to the off position, the rotating shaft cannot drive the crankshaft, and the rotating shaft is idling without bearing the load. The plate leaves the plumb line quickly and transitions to a state where it is easy to exert force. At the same time, the clutch structure is switched to the closed position, and the rotating shaft drives the crankshaft to rotate. It can be seen that when the rotating bearing is loaded, the pedal has left the plumb line, overcoming Eliminate the disadvantages of bicycle riding effort

Abstract

The invention relates to a bicycle, comprising a vehicle frame, a handlebar, a front wheel, a rear wheel, a crankshaft, a rotating shaft, a clutch structure, and two connecting rods; a circular hole is arranged in the center of the crankshaft, and the rotating shaft runs through the circular hole, and the clutch structure is provided Between the rotating shaft and the crankshaft; it also includes a transmission device; the transmission device is used to transmit the user's operation action to the clutch structure, so that the clutch structure can choose one of the first state and the second state; if the clutch The structure is in the first state. When the pedal is close to the plumb line, the clutch structure switches to the off position, and the rotating shaft cannot drive the crankset. When the pedal leaves the plumb line, the clutch structure switches to the close position, and the rotating shaft can drive the crankset; If the clutch structure is in the second state, the clutch structure is always kept in the closed position, and the rotating shaft can drive the crankshaft. The invention has the following advantages: it is convenient to ride, and the user can randomly change the way of exerting force.

Description

technical field [0001] The invention relates to the field of bicycle manufacture. Background technique [0002] Bicycle can be seen everywhere as a kind of walking-replacing tool, and bicycle generally comprises vehicle frame, front wheel, trailing wheel, chainring, but the bicycle of prior art has a common shortcoming: riding is laborious, not too convenient, when two pedals of bicycle When the boards are distributed forward and backward, it is easy for the rider to apply force to the pedals, as long as the pedals are pushed with the feet, the movement is very natural and coordinated. It is difficult for the rider to exert force on the pedals, and the cyclist must make the following actions: the sole of the left foot pushes one pedal forward, the sole of the right foot pushes the other pedal backward, the sole of the left foot forms an acute angle with the left calf, and the sole of the right foot The sole of the foot forms an obtuse angle with the right calf. This movemen...
