The same reference numerals in the drawings represent the same or similar parts, and their repeated descriptions will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0039] In this exemplary embodiment, a treadmill running device is first provided. Figure 1-7 As shown, the running device includes: a treadmill 100 , two side frames 200 arranged opposite to each other, a folding mechanism 300 and a transmission mechanism 400 .

[0040] Specifically, the treadbelt 100 includes a plurality of strip rigid members 101, and a first gap is provided between two adjacent strip rigid members 101. Two adjacent strip rigid members 101 are not connected, and have a first gap, and the first gap can meet the space required for the treadbelt 100 to be folded. The shapes of the two opposite long sides of the strip rigid member 101 can be inclined surfaces, or surfaces in a “>” shape, but are not limited thereto. A plurality of protrusions can be provided on the upper surface of the strip rigid member 101 for anti-slip, and the shapes of the protrusions can be circular, rectangular, triangular, diamond-shaped, etc., but are not limited thereto. In addition, the material of the strip rigid member 101 can be steel plate, plastic steel, etc., but are not limited thereto.

[0041] The two side frames 200 are arranged on both sides of the running belt 100, and each of the side frames 200 includes a first frame 201 and a second frame 202 that abut against each other or have a second gap. The first frame 201 and the second frame 202 are not in a fixed connection state, and the abutment between the two or the second gap is provided to provide a structure or space required for folding. When folding is required, it can be done by folding the second frame 202. The folding situation will be described in more detail later.

[0042] It should be noted that the second transverse supporting member 700 may be disposed at the bottom of the first frame 201 and the second frame 202, and the number of the second transverse supporting member 700 may be multiple, and may be specifically disposed at the abutment of the first frame 201 and the second frame 202 or below the second gap, and may also be disposed at the middle position of the first frame 201 or at the end of the first frame 201 away from the second frame 202. The second transverse supporting member 700 is used to support the first frame 201 and the second frame 202. In addition, further, the second transverse supporting member 700 may be a plate, or a support block, etc., and a support foot is disposed below the second transverse supporting member 700 for supporting the running device.

[0043] The specific structure of the folding mechanism 300 is described in detail below.

[0044] Please refer to Figure 4 and Figure 5 The folding mechanism 300 includes: a shaft 301, and a rotating member 302 mounted on the shaft 301 and capable of relative rotation with the shaft 301. The shaft 301 and the first frame 201 are fixedly or non-fixedly connected. For example, the shaft 301 can be fixedly connected to the first frame 201 by a connecting member such as a bolt, and the rotating member 302 can be sleeved on the shaft 301 and can rotate around the shaft 301; the shaft 301 can be non-fixedly connected to the first frame 201 by a connecting member (for example, the connecting member here can adopt a structure similar to the rotating member 302), for example, one end of the connecting member can be sleeved on the shaft 301, and the connecting member and the shaft 301 can rotate relative to each other (in this case, the connection between the shaft 301 and the first frame 201 is a non-fixed connection), and the other end of the connecting member is fixedly connected to the first frame 201.

[0045] The rotating member 302 and the second frame 202 are fixedly connected, and the second frame 202 can rotate around the shaft member 301 under the action of the rotating member 302 .

[0046] The shaft 301 may be a pin, a rotating shaft, etc. The shaft 301 and the first frame 201 are connected via a sleeve 303 , a part of the sleeve 303 is sleeved on the shaft 301 , and the sleeve 303 is fixedly connected to the first frame 201 .

[0047] In this embodiment, the first frame 201 and the sleeve 303 are fixedly connected, and the sleeve 303 is sleeved on the shaft 301, and the rotating member 302 is also sleeved on the shaft 301. The rotating member 302 and the second frame 202 are fixedly connected, so that when a rotational force is applied to the second frame 202, the second frame 202 can rotate around the shaft 301, thereby realizing the folding of the second frame 202. In addition, it should be noted that both the rotating member 302 and the sleeve 303 can be sleeved on the shaft 301, and the specific installation method can be to insert the pin into the rotating member 302 and the sleeve 303. On this basis, limit members, such as limit cards, limit blocks, etc., but not limited to this, can be set at both ends of the pin to prevent the pin from coming off the rotating member 302 and the sleeve 303.

[0048] It should be noted that the shaft member 301 can be arranged on the upper surface of the side frame 200, or can be arranged above the side frame 200. When arranged above the side frame 200, it can be supported by a support member. Usually, the axis height of the shaft member 301 is the same as the height of the treadbelt 100 or the height of the shaft member 301 is higher than the height of the treadbelt 100. Such an arrangement allows the treadbelt 100 to rotate with the shaft member 301 as the center to achieve folding.

[0049] The specific structure of the transmission mechanism 400 is described below.

[0050] The transmission mechanism 400 includes an annular flexible belt 401 and a power assembly 402. The annular flexible belt 401 is sleeved on the power assembly 402 and moves or rotates under the drive of the power assembly 402. The annular flexible belt 401 is located on the inner side of the running belt 100 and is fixedly connected to the running belt 100. Transmission process: After the power assembly 402 is started, since the annular flexible belt 401 and the running belt 100 are fixedly connected, the power assembly 402 drives the annular flexible belt 401 and the running belt 100 to move or rotate at the same time.

[0051] It should be pointed out that when the second frame 202 is folded, the tread belt 100 and the endless flexible belt 401 are folded synchronously.

The present application overcomes the discontinuity caused by the presence of the running board in the conventional technology, and can make the runner's foot feel more comfortable, and also eliminates the multi-layer structure used with the running board, making it easier to fold and use.

[0053] Based on the above examples, please refer to Figure 5 Optionally, in some embodiments, the rotating member 302 includes two sleeve portions and a connecting portion, the two sleeve portions are fixedly connected to the connecting portion, the two sleeve portions are sleeved on the shaft member 301, and the connecting portion is fixedly connected to the second frame 202. The sleeve portions are used to realize the sleeve connection and rotation between the rotating member 302 and the shaft member 301, and the connecting portion is used to realize the fixed connection between the rotating member 302 and the second frame 202, so that the second frame 202 can rotate under the rotation of the rotating member 302, thereby realizing the folding of the second frame 202. For a schematic diagram of the structure of the running device after folding, please refer to Figure 8 .

[0054] Optionally, in some embodiments, the running device further includes: two pairs of longitudinally arranged support plates 500 and a plurality of first transverse supporting members 600 for supporting the treadbelt 100 and the endless flexible belt 401 .

[0055] Specifically, please refer to Figure 3 and Figure 4 There is a third gap between the two support plates 500 (to provide folding space for folding), and each support plate 500 is provided with a plurality of first guide wheels 501 and a plurality of second guide wheels 502, wherein the diameter of the first guide wheel 501 is greater than the diameter of the second guide wheel 502 or the height of the first guide wheel 501 is greater than the height of the second guide wheel 502. Please refer to Figure 6The inner side of the endless flexible belt 401 has an annular protrusion 4011, the first guide wheel 501 contacts the non-annular protrusion of the endless flexible belt 401, and the second guide wheel 502 contacts the annular protrusion 4011 of the endless flexible belt 401. As for the arrangement of the first guide wheel 501 and the second guide wheel 502, a first guide wheel 501 can be arranged every three or four second guide wheels 502, and the non-protrusion and the annular protrusion 4011 of the endless flexible belt 401 are supported and guided by the first guide wheel 501 and the second guide wheel 502, so that the running belt 100 can move stably.

[0056] In addition, in some embodiments, a flexible sleeve 5011 is provided on the outer periphery of the first guide wheel 501 to flexibly support the annular flexible belt 401 and reduce the possibility of damage to the annular flexible belt 401 .

[0057] It can be understood that the support plate 500, the first frame 201 and the second frame 202 are respectively fixedly connected to the first transverse supporting member 600. Specifically, one end of the first transverse supporting member 600 is fixedly connected to the support plate 500, and the other end is fixedly connected to the side frame 200, so as to support the running belt 100 and the endless flexible belt 401.
