The reciprocating mechanism 100 may further include a pad 140 and a bracket 150. The seat cushion 140 is pivotally connected to the first connector 110, and the second connector 120 is pivotally connected to one side of the bracket 150. Therefore, through the mutual connection between the first connecting member 110, the second connecting member 120, the seat cushion 140 and the bracket 150, a periodic motion along the arc-shaped trajectory of the simulated horse riding is formed. In addition, a first angle is formed between the first follower 131 and the second follower 132, and a second angle is formed between the second link 120 and the second follower 132. In an embodiment, the first included angle may be greater than or equal to 120 degrees, and the second included angle may be greater than 0.1 degrees. By controlling the angle range of the first included angle and the second included angle, the direction of the periodic motion formed by the reciprocating mechanism 100 can be controlled.

The reciprocating mechanism 100 of the present invention can not only form a reciprocating motion simulating riding, but also drive the bicycle 200 to move at the same time to achieve the traveling effect. Therefore, in the embodiment of FIG. 1, the bicycle 200 includes a frame 210 for mounting the reciprocating mechanism 100. The frame 210 includes body tubes 211, 212, and 213. The rotation axis 133 of the reciprocating mechanism 100 is installed on the body tube 211. One end of the bracket 150 is pivotally connected to one side of the body tube 212. One end of the seat cushion 140 is pivotally connected to the first connecting member 110, and the other end is pivotally connected to one end of the body tube 213. The bicycle 200 also includes a gear 214, a belt 215, and a first tire 216. The gear 214 is sleeved on the rotation axis 133, the belt body 215 is wound on the gear 214, and interlocks the first tire 216. The bicycle 200 further includes a second tire 217 mounted on the frame 210 and driven to rotate by the first tire 216. Therefore, when the reciprocating mechanism 100 forms a reciprocating motion, it can drive the rotation axis 133 of the crank shaft 130 to rotate, thereby connecting The moving gear 214 rotates, and drives the first tire 216 of the bicycle 200 to rotate through the belt body 215, thereby driving the second tire 217 to rotate, so that the bicycle 200 can travel displaceably. Therefore, the reciprocating motion of the reciprocating mechanism 100 can be used as the traveling power of the bicycle 200.

The following paragraphs will explain the operating mechanism of the new reciprocating mechanism 100. For ease of understanding, each element will be simplified as a line, and will be described in a schematic plan view, and the size ratio of several elements will be adjusted appropriately to more clearly explain the action mechanism.

FIG. 6, FIG. 7, FIG. 8, and FIG. 9 are schematic diagrams illustrating the first, second, third, and fourth operating states of the reciprocating mechanism 100, respectively. Please refer to Figures 1 to 5 together. In FIG. 6, a first angle θ1 is formed between the first follower 131 and the second follower 132, and a second angle θ2 is formed between the second follower 132 and the second connector 120. In the embodiment of FIG. 6, the first included angle θ1 is 150 degrees, and the second included angle θ2 is 3.6 degrees. When the bracket 150 is stepped on by the user and pivots downward, the second connecting member 120 is pivotally pivoted, and at the same time, the second driven member 132 is also rotated clockwise around the rotation axis 133. At this time, since the first follower 131 and the second follower 132 are respectively located on opposite sides of the rotation axis 133, the second follower 132 also rotates the first follower while rotating clockwise The member 131 rotates clockwise. Since the relative positions of the first follower 131 and the second follower 132 are fixed, and the first connecting member 110 is linked to the first follower 131, the first connection is driven by the rotation of the first follower 131 The member 110 pivots upward, and at this time, the seat cushion 140 is also caused to pivot upward. Therefore, in the present invention, when the bracket 150 pivots downward, the seat cushion 140 pivots upward, as can be seen from the continuous actuation state in FIGS. 7 to 8. In Figure 8, when When the bracket 150 is stepped on and pivoted downward to a lowest position, the seat cushion 140 is also pivoted upward to a highest position. At this time, the seat cushion 140 starts to pivot downward due to the weight pressed by the rider, and the first connecting member 110 is pivoted downward, and at the same time drives the first follower 131 to continue clockwise around the rotation axis 133 The direction rotates, so that the second follower 132 also continues to rotate clockwise around the rotation axis 133. At this time, the rotation of the second follower 132 causes the bracket 150 to pivot upward. Therefore, when the seat cushion 140 pivots downward, the bracket 150 pivots relatively upward. This can be seen from the continuous actuation state of Figure 8 to Figure 9. Therefore, the first follower 131 and the second follower 132 passing through the crank shaft 130 rotate around the rotation axis 133, so that the first connecting member 110, the seat cushion 140, the second connecting member 120 and the bracket 150 are pivotally linked to each other The pendulum forms a reciprocating motion similar to horseback riding. Furthermore, the first follower 131 and the second follower 132 rotate relative to the rotation axis 133 relative to each other, which can respectively drive the first connecting member 110 and the second connecting member 120 to form a circular arc-shaped trajectory. Periodic reciprocating motion. When the rider rides on the seat cushion 140, not only does the seat cushion 140 form a reciprocating pivot, but also cooperates with the stepping action of the foot on the bracket 150, you can feel the complex movement trajectories above, below, front, and back The reciprocating movement can simulate the effect of horseback riding more realistically, and achieve the purpose of full body movement. In more detail, the seat cushion 140 is for riding the hips of the rider, and the first connecting member 110 is actuated by the action of the hip; the bracket 150 is for stepping on the foot of the rider, and is linked by the action of the foot The second connector 120 is activated. In this way, the bicycle 200 can correspond to the movements of the hips and feet of the rider through the first connecting member 110 and the second connecting member 120, respectively, to achieve a more comprehensive sports effect. As in the embodiment of FIG. 1, when the gear 214 is installed, the rotation through the rotation axis 133 of the crank shaft 130 can also drive the gear 214 to rotate, and the belt body 215 to drive the first The tire 216 rotates to drive the second tire 217 to rotate so that the entire bicycle 200 can be displaced forward. In other embodiments, a motor (not shown) may be installed to automatically drive the gear 214 to rotate.

Please continue to refer to FIG. 10, which is a schematic diagram illustrating the modulation of the first included angle θ1 between the first follower 131 and the second follower 132 in another embodiment of the present invention. The present invention can finely adjust the relative geometric relationship of the movement of each element in the reciprocating mechanism 100 by adjusting the angle value of the first included angle θ1. In the aforementioned embodiment of FIG. 6, the first included angle θ1 between the first follower 131 and the second follower 132 is 150 degrees. In the embodiment of FIG. 10, the first included angle θ1 between the first follower 131 and the second follower 132 is 120 degrees. In this way, when the reciprocating mechanism 100 forms a reciprocating action, it can still maintain the rotation axis 133 of the crank shaft 130 to rotate clockwise, so as not to cause conflicts between the interlocking operations of the components, resulting in component damage or mutual interference. . It should also be mentioned that in the present invention, when the first included angle θ1 between the first follower 131 and the second follower 132 is greater than or equal to 120 degrees, and between the second link 120 and the second follower 132 When the second included angle θ2 is greater than 0.1 degrees, it can form a continuous reciprocating action as shown in Figures 6 to 9 of the present invention without causing interference or conflict between the components. Therefore, it is very important to adjust the angle range of the first included angle θ1 and the second included angle θ2. In addition, since the reciprocating mechanism 100 rotates the crank shaft 130 to link the first connecting member 110 and the second connecting member 120 to reciprocate, it can be used as a driving force for the bicycle 200. When possible, the rotation axis 133 of the crank shaft 130 can rotate clockwise or counterclockwise. However, when rotating counterclockwise, it is easy to cause the components to interfere with each other or cause idle rotation. Therefore, in other embodiments, the bicycle 200 may further include a ratchet (not shown). The ratchet system can be used to restrict the first connector 110 and the second connector 120 The direction of the pivoting reciprocating cycle. In other words, through the ratchet unidirectional limit function, the rotation axis 133 of the crank shaft 130 can be ensured to rotate clockwise, thereby ensuring that the first connecting member 110 and the second connecting member 120 are clockwise along the arc-shaped trajectory Periodic reciprocating motion.

Please continue to refer to FIG. 11, which is a schematic flowchart of a method for forming a reciprocating motion according to an embodiment of the present invention. According to the structure of the aforementioned reciprocating mechanism 100, the present invention provides a method for forming a reciprocating motion, which includes: Step S101 is to provide a crank shaft 130, wherein the crank shaft 130 includes a rotating shaft 133 and a relatively rotatable shaft 133 A first follower 131 and a second follower 132; Step S102 provides a first connection member 110, so that the first connection member 110 is linked to the first follower 131; Step S103 provides a second connection 120, the second connecting member 120 is linked to the second follower 132; step S104 causes the first follower 131 and the second follower 132 to rotate around the rotation axis 133 to connect the first connecting member 110 and The second connecting members 120 are pivoted reciprocally and cyclically along a circular arc path.

Therefore, the present invention can apply the reciprocating mechanism 100 to a bicycle 200, a horse-riding machine or the like, and through the pivotal swing of the first connecting member 110 and the second connecting member 120, respectively drive the hips and feet of the rider to form respectively Periodic motion with one of circular arc trajectories. With this, the effect of simulating horseback riding can be achieved. If installed on the bicycle 200, it can also be used as a power source to drive the bicycle 200 forward.
