In one of the optional embodiments, as shown in FIG. 5 , also due to the shape setting of the rotating piece 43 and the position setting of the third through hole 433 in the rotating piece 43, the second group of rotating pieces B The rotating piece 43 will not block the fourth shaft 47 passing through the third through hole 433 of the rotating piece 43 in the first group of rotating pieces A.

Optionally, in the process of unfolding and folding the front running board 1 and the rear running board 2, in order to prevent the user from being hurt by too fast unfolding or folding, the corresponding treatment can be as follows: as shown in Figure 3, the hinge structure 4 also Including a hydraulic cylinder 49; the first hinge body 41 is provided with an installation groove 416 for installing the hydraulic cylinder 49; the cylinder body 491 of the hydraulic cylinder 49 is installed in the installation groove 416; the end of the hydraulic rod 492 of the hydraulic cylinder 49 is provided with a second Four through holes 493 ; the hydraulic rod 492 is installed on the first rotating shaft 44 through the fourth through hole 493 .

Optionally, the shape and size of the fourth through hole 493 may be the same as that of the first through hole 431 .

In one optional embodiment, the hydraulic cylinder 49 is used to apply rotation resistance to reduce the rotation speed when the first hinge body 41 and the second hinge body 42 rotate. Hydraulic cylinder 49 is made up of cylinder body 491 and hydraulic rod 492, and hydraulic rod 492 can move in cylinder body 491, and the pressure in cylinder body 491 is not equal to the pressure of atmosphere, and hydraulic rod 492 can be subjected to resistance when moving in cylinder body 491. Wherein, by setting the hydraulic cylinder 49 , when the hydraulic rod 492 is pulled and pushed, the hydraulic rod 492 has proper resistance in the hydraulic cylinder 49 .

The installation of the hydraulic rod 492 of the hydraulic cylinder 49 can be completed in the above step 3, and the corresponding processing can be, at first, the hydraulic rod 492 of the hydraulic cylinder 49 is placed between the two rotating plates 43 of the first group of rotating plates A, as Figure 3 shows. Then, align the center of the first through hole 431 of the first group of rotating pieces A with the center of the fourth through hole 493 of the hydraulic rod 492 . Finally, pass the first rotating shaft 44 through the first rotating shaft slot 411 , the second rotating shaft slot 412 , the first through hole 431 of the first group of rotating pieces A, and the fourth through hole 493 of the hydraulic rod 492 . The cylinder body 491 of the hydraulic cylinder 49 is fixed in the installation groove 416 of the first hinge body 41 .

In this way, in the process of folding the front running board 1 and the rear running board 2, that is, during the process of the angle between the front running board 1 and the rear running board 2 from 180 degrees to 0 degrees, the hydraulic rod 492 is stretched state. During the process of unfolding the front running board 1 and the rear running board 2 , that is, during the process of the angle between the front running board 1 and the rear running board 2 from 0 degree to 180 degrees, the hydraulic rod 492 is in a compressed state. Therefore, the slow descent can be realized by adjusting the hydraulic pressure in the hydraulic cylinder 49 .

The concrete structure of hydraulic cylinder 49 can be, be provided with hydraulic cylinder tube and hydraulic oil tank in cylinder body 491, they link to each other by small hole, hydraulic rod 492 is connected piston in cylinder body 491, and piston is connected to piston in cylinder body 491. Activities in the hydraulic cylinder. When the hydraulic rod 492 is in a stretched state, hydraulic oil flows from the oil tank into the hydraulic cylinder barrel through the small hole until the hydraulic cylinder barrel is full of hydraulic oil. In this way, when the angle between the front running board 1 and the rear running board 2 is expanded from 0 degrees to 180 degrees, due to the hydraulic pressure, the compression of the hydraulic rod 492 is resisted, showing a slow-down effect, avoiding the front running board when unfolding. The included angle between 1 and the rear running board 2 is too fast from 90 degrees to 180 degrees and hurts the user, thereby protecting the user.

Optionally, the above-mentioned hydraulic cylinder 49 can be installed only in the first hinge body 41 in the above-mentioned hinge structure 4, or the above-mentioned hydraulic cylinder 49 can be installed in both the first hinge body 41 and the second hinge body 42 at the same time, and the hydraulic cylinder 49 can be installed according to the actual situation. It depends on the situation and is not limited here. Wherein, the process of installing the above-mentioned hydraulic cylinder 49 in the second hinge body 42 is the same as the above-mentioned process of installing the above-mentioned hydraulic cylinder 49 in the first hinge body 41 . Optionally, the two-way slow down can be realized by setting and arranging the same hydraulic cylinder on the second hinge body 42 .

Optionally, when the hydraulic cylinder 49 is not installed on the second hinge body 42, a lightening hole 426 can be set on the second hinge body 42; Also can be used as the installation groove of hydraulic cylinder 49.

Optionally, the above-mentioned hydraulic cylinder 49 can also be replaced by other structures with a buffer function, for example, a spring 410 as shown in FIG. 7 , and the spring 410 is installed on a spring seat. During the unfolding and folding process of the first hinge body 41 and the second hinge body 42 , the elastic force of the spring 410 is used to buffer the unfolding and folding. During the folding and unfolding process of the treadmill, the state of the spring 410 can be set according to many times of trial and error. Describe its buffering process in detail with an embodiment below:

In an optional embodiment, the state of the spring 410 may be that when the angle between the first hinge body 41 and the second hinge body 42 is 180 degrees, the spring 410 is in a compressed state; When the angle between 41 and the second hinge body 42 is 90 degrees, the spring 410 is in a normal state; when the angle between the first hinge body 41 and the second hinge body 42 is 0 degrees, the spring 410 is in tension state. In this way, during the folding process, the angle between the first hinge body 41 and the second hinge body 42 ranges from 180 degrees to 90 degrees, because the user is relatively easy to control, and no buffering is required; from 90 degrees to 0 degrees During the process, the spring 410 is always stretched to generate resistance to the folding, thereby playing a buffering role. During the unfolding process, when the included angle between the first hinge body 41 and the second hinge body 42 is from 0° to 90°, the user is less likely to be injured, because the elasticity of the spring 410 is within an appropriate range. , the elastic force will not be too large, and this process does not need buffering; during the process of unfolding from 90 degrees to 180 degrees, the spring 410 is always compressed, which creates resistance to the unfolding, so that it can act as a buffer to prevent hitting the user's body foot.

Optionally, by setting the included angle between the first hinge body 41 and the second hinge body 42 when the spring is in a normal state, one-way slow down can also be realized. For example, it is in a normal state at 0 degrees (or an angle greater than 0 degrees and less than 90 degrees), and it is in a compressed state at 180 degrees, and it can also realize a slow drop in the process of 0 degrees to 180 degrees.
