Embodiment 1
[0035] Such as figure 1 with Figure 7 As shown, the bicycle labor-saving mechanism is connected to the vehicle frame 9, including the central axis 1 horizontally pierced on the vehicle frame 9, and two guide rails with annular guide grooves 21 respectively sleeved on the outer sides of the two ends of the central axis 1. 2 and two pedal rods 3 in the shape of square rods, the two pedal rods 3 are arranged perpendicular to the central axis 1, and the inner ends of the pedal rods 3 are connected with guides 4 that snap into the corresponding guide grooves 21, Foot pedals 5 are connected to the outer ends of the pedal rods 3 , and the distance between the pedals 5 and the central axis 1 increases or decreases gradually when the pedal rods 3 move along the guide groove 21 . In this embodiment, the two guide rails 2 are substantially disc-shaped and fixed on both sides of the vehicle frame 9 in an axisymmetric manner. 21 is roughly in the shape of a duck egg; the positions where...
Embodiment 2
[0044] Such as Figure 5 As shown, the solution of this embodiment is roughly the same as that of Embodiment 1, the difference is that: the number of the rolling element 3 42 is only one and it is rotatably connected to the inner end of the pedal rod 3; the guide groove 21 is round Shape; Pedal bar 3 is round bar shape.
Embodiment 3
[0046] Such as Image 6 As shown, the solution of this embodiment is roughly the same as that of Embodiment 1, except that the number of rolling elements 3 42 is three, two of which are rotatably connected to both sides of the pedal bar 3, and the third It is rotatably connected to the inner end of the pedal rod 3 .
