Exercise bicycle with reciprocating mechanism of pedal along track

Abstract

The invention relates to an exercise bicycle with a reciprocating mechanism of a pedal along a track. The exercise bicycle mainly comprises a main frame, a crank, an adjusting rod, a rotating shaft, the pedal and the track, wherein the main frame is used for supplying a base to a motion; the crank is used for transferring kinetic energy; a distance can be adjusted by the adjusting rod; the track is connected with a rotating base and is used for supplying a synchronous motion trail to a sliding base; the crank is connected with the rotating base; the track is connected with a swinging rod through a second connecting rod; the rotating shaft is used for fixing the swinging rod and causing the swinging rod to move along the rotating shaft; the sliding base is connected with the adjusting rod through a first connecting rod; the pedal is mounted on the sliding base; and under the driving of an input torque, a circular motion of the crank is converted into a reciprocating motion of the pedal on the track by a planar four-rod mechanism which is composed of the track, the first connecting rod, the second connecting rod and the adjusting rod, so as to change a stride of a sporter, wherein a change curve of the stride is a sine curve. The exercise bicycle provided by the invention has the beneficial effects that the reciprocating mechanism is the planar four-rod mechanism composed of the track and the connecting rods; the periodical change of the stride is realized by using the motion mechanism of the pedal along the track, so that human motion is more suitable and comfortable; and the cardio-pulmonary function and the physical coordination of a body builder and a rehabilitee are increased.

Description

technical field [0001] The invention relates to the field of exercise bikes, in particular to an exercise bike with a pedal reciprocating mechanism along a track. Background technique [0002] The pedal structure of a traditional exercise bike, such as Figure 5 Shown: it includes a frame 101 for installing a transmission system and a resistance system, a crank 102 for transmitting external torque, a rotating seat 103, a pedal connecting rod 104, an adjusting rod 105, a rocking rod 106, a rotating shaft 107 and a pedal 108 ; When the user moves, the athlete first drives the crank 102 to rotate, and the crank 102 drives the pedal link 104 to move through the rotating seat 103 . The pedal link 104 is connected with the rotating shaft 107 through the adjustment rod 105 and the rocking rod 106; the pedal 108 is fixed on the pedal link 104 through screw connection, when the user moves, the hand drives the rocking rod 106, and the leg drives the crank 102 Movement. Through the t...
