[0018] Please refer to Figure 1 、 Figure 2 、 Figure 3 As shown in FIGS., a running board folding structure of a treadmill provided in this embodiment includes: an upper hinge body 1, one end of the upper hinge body 1 is rotatably connected to a rotating member I 3, and the other end is rotatably connected to a rotating member III 4. A rotating member II 5 is rotatably connected inside the rotating member III 4. One end of the rotating member I 3 away from the upper hinge body 1 is rotatably connected to the rotating member II 5. One end of the rotating member II 5 away from the rotating member I 3 is rotatably connected to a lower hinge body 2. One end of the lower hinge body 2 away from the rotating member II 5 is rotatably connected to a rotating member IV 6. One end of the rotating member IV 6 away from the lower hinge body 2 is rotatably connected to the rotating member III 4.

[0019] The rotating connection manner between the hinge bodies (1, 2) and the rotating members (3, 4, 5, 6) is hinged through a rotating shaft 7, and the rotating connection manner between the rotating members (3, 4, 5, 6) is also hinged through the rotating shaft 7.

[0020] A washer 8 is padded at the connection of the rotating shaft 7 between the upper hinge body 1 and the rotating member I 3. The thickness of the washer 8 is the same as that of the rotating member II 5, so that the rotating member I 3 is parallel to the rotating member II 5 after connection.

[0021] A through hole I 10 is opened on one side of the rotating member II 5. The through hole I 10 is semi-open. The rotating shaft 7 at the rotating connection between the upper hinge body 1 and the rotating member III 4 is buckled with the through hole I 10 of the rotating member II 5. The rotating member II 5 is disengaged from the rotating shaft 7 at the rotating connection between the upper hinge body 1 and the rotating member III 4 during rotation.

[0022] A through hole II 9 is opened on one side of the rotating member III 4. The through hole II 9 is semi-open. The rotating shaft 7 at the rotating connection between the lower hinge body 2 and the rotating member II 5 is buckled with the through hole II 9 of the rotating member III 4. The rotating member II 5 is disengaged from the rotating shaft 7 at the rotating connection between the lower hinge body 2 and the rotating member II 5 during rotation.

[0023] Both the rotating member II 5 and the rotating member III 4 are U-shaped to prevent the rotating member from hitting the hinge body when it rotates. They have the same shape and size. The rotating member II 5 and the rotating member III 4 are symmetrically arranged up and down with respect to their hinge point. The rotating member I 3 and the rotating member IV 6 have the same shape and size. The rotating member I 3 and the rotating member IV 6 are symmetrically arranged up and down with respect to the hinge point of the rotating member II 5 and the rotating member III 4. The upper hinge body 1 and the lower hinge body 2 have the same shape and size. The hinge body and the lower hinge body 2 are symmetrically arranged up and down with respect to the hinge point of the rotating member II 5 and the rotating member III 4.

[0024] When the running platform folding structure of the treadmill of the present utility model is in use, the upper hinge body 1 is fixed to the rear running platform by bolts or welding, and the lower hinge body 2 is fixed to the front running platform by bolts or welding. After the treadmill is placed horizontally on the ground, the lower hinge body 2 is placed horizontally following the front running platform. When the rear running platform is rotated, the upper hinge body 1 rotates together with the rear running platform. The angle between the upper hinge body 1 and the lower hinge body 2 changes from 0 to 180 degrees during the rotation. After the unfolding is completed, the unfolding process of the running platform of the treadmill is completed. During the unfolding process, as the rotation progresses, the angle between the rotating member I 3 and the upper hinge body 1 increases, and the angle between the rotating member I 3 and the rotating member II 5 decreases. The through hole I 10 of the rotating member II 5 disengages from the rotating shaft 7 at the rotation connection of the upper hinge body 1 and the rotating member III 4. While the rotating member II 5 rotates around the lower hinge body 2, the angle between the rotating member IV 6 and the lower hinge body 2 increases, and the angle between the rotating member IV 6 and the rotating member III 4 decreases. The through hole II 9 of the rotating member III 4 disengages from the rotating shaft 7 at the rotation connection of the lower hinge body 2 and the rotating member II 5. The rotating member III 4 rotates around the upper hinge body 1. During the rotation process, the hinge points of the rotating shafts 7 of the rotating member III 4 and the rotating member II 5 are synchronously adapted to each other to prevent the problem of asynchronous movement of the two hinge bodies.

[0025] When folding is required, the running platform is placed in a horizontal position, and the rear running platform is flipped upward, driving the upper hinge body 1 to rotate together with the rear running platform. The angle between the upper hinge body 1 and the lower hinge body 2 changes from 180 to 0 degrees during the rotation. During the rotation process, the angle between the rotating member I 3 and the upper hinge body 1 decreases, and the angle between the rotating member I 3 and the rotating member II 5 increases. The through hole I 10 of the rotating member II 5 engages with the rotating shaft 7 at the rotation connection of the upper hinge body 1 and the rotating member III 4 along its arc-shaped movement trajectory. While the rotating member II 5 rotates around the lower hinge body 2, the angle between the rotating member IV 6 and the lower hinge body 2 decreases, and the angle between the rotating member IV 6 and the rotating member III 4 increases. The through hole II 9 of the rotating member III 4 engages with the rotating shaft 7 at the rotation connection of the lower hinge body 2 and the rotating member II 5 along its arc-shaped movement trajectory. The rotating member III 4 rotates around the upper hinge body 1.
