It should be noted that the parallelogram mechanism is a common four-bar structure, in which the two cranks have the same length and are identical in direction of rotation (in this particular embodiment, the two cranks are the driving link 1 and the driven link 2, respectively, the links for connecting the two cranks have the same length as the frame bar, in this particular embodiment, the hinge points of the driving link 1 and the driven link 2 with the vehicle bottom form a virtual frame bar, the length of which is D1, and the hinge points of the driving link 1 and the driven link 2 with the pedal body 3 form a virtual link, the length of which is D2, so as to satisfy d1=d2, as shown in fig. 1 c).
