The frame 21 has a front connecting end 211 and a rear connecting end 212 opposite to each other along the horizontal direction, and a pivot end 213 located between the front connecting end 211 and the rear connecting end 212. The frame 21 is pivotally connected to the pivot point 121 via the pivot end 213, so that the frame 21 can be swingably arranged on the base 11; specifically, the frame 21 is also rectangular corresponding to the base 11, and two opposite reinforcement bars 214 are arranged at the bottom of the frame 21 along the horizontal direction, and the front connection end 211 and the rear connection end 212 are respectively arranged on the two aforementioned reinforcement bars 214, and the aforementioned reinforcement bars 214 are hollow tubes and have a rectangular cross-sectional shape. A handrail is erected on the frame 21, and the handrail and the running belt body 22 jointly define a running space, and the running belt drive motor 23 drives the running belt body 22 to move around the frame 21 in a circular motion, which belongs to the existing technology, so it will not be described in detail here.

[0038] The adjustment unit 3 has a chain 31, a chain drive motor 32, four idler wheels 33 and an elastic idler wheel 34. The chain drive motor 32 includes a motor body 323, a reducer 322 and a driving sprocket 321. The opposite ends of the chain 31 are respectively connected to the front connecting end 211 and the rear connecting end 212, and are wound around the driving sprocket 321, the four aforementioned idler wheels 33 and the elastic idler wheel 34. The motor body 323 is fixed to the base 11 and connected to the reducer 322. The driving sprocket 321 is set on the output shaft of the reducer 322. The four aforementioned idler wheels 33 are rotatably disposed in sequence on the base 11 along the horizontal direction.

[0040] See also Figure 2 , Figure 6 and Figure 7In addition to maintaining the running belt unit 2 in a horizontal state when in use, the utility model can also adjust the angle of the running belt unit 2 to simulate an uphill state; specifically, the chain drive motor 32 is started, so that the chain drive motor 32 drives the driving sprocket 321 to rotate and drive the chain 31 to move, and one end of the chain 31 will be driven by the driving sprocket 321 to move in the direction of the driving sprocket 321 and pull the frame 21, and the frame 21 rotates and swings relative to the base 11 with the pivot end 213 as the center, and the frame 21 swings in different directions according to the different directions in which the chain drive motor 32 drives the driving sprocket 321 to rotate. For example, the frame 21 is pulled so that the rear connection end 212 of the frame 21 approaches the base 11 and the front connection end 211 moves away from the base 11. The chain 31 connected to the front connection end 211 is pulled by the frame 21, so that the chain 31 is maintained at a certain tension and does not get loose. At the same time, the elastic idler wheel 34 can also continue to stop at the chain 31 according to the different positions of the chain 31 after the swing, so that the chain 31 maintains tension; in this way, the frame 21 and the base 11 are sandwiched at an elevation angle to simulate the state of going uphill. When the elevation angle is adjusted to the maximum value, the frame 21 just abuts against the aforementioned rear end abutment portion 14, so that the frame 21 can be firmly against the base 11.

[0041] See also Figure 2 , Figure 8 and Fig. 9 , the utility model can also adjust the angle of the treadmill unit 2 to simulate a downhill state; specifically, similar to the above embodiment, the chain drive motor 32 is used to drive the drive sprocket 321 to rotate and drive the chain 31 to move, but the difference is that the direction of rotation of the drive sprocket 321 is opposite to the above rotation direction, so that the front connection end 211 of the frame 21 is close to the base 11, and the rear connection end 212 is away from the base 11, so that the frame 21 and the base 11 are inclined at an angle to simulate a downhill state.

[0042] See also Figure 2 and Fig.10In order to enable the frame 21 to pivot and swing relative to the base 11, the frame 21 and the base 11 need to be arranged at a distance from each other, so an accommodating space is formed between the frame 21 and the base 11, and the adjustment unit 3 is just arranged in the accommodating space; and in order to prevent the user from accidentally touching the chain 31 or the chain drive motor 32 and other parts arranged in the accommodating space, the utility model further includes a shield 6, which is telescopically connected between the base 11 and the frame 21 along the height direction, and is arranged around the periphery of the base 11 and the frame 21, and surrounds and closes the accommodating space, thereby not only preventing the user from touching the chain 31 or the chain drive motor 32 and other parts, but also beautifying the appearance of the utility model, so that the appearance of the seat unit 1 combined with the running belt unit 2 has integrity.

[0043] Based on the description of the above embodiments, the operation, use and effects of the present invention can be fully understood. However, the above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of implementation of the present invention. That is, simple equivalent changes and modifications made according to the claims and the description of the present invention are all within the scope of the present invention.
