DETAILED DESCRIPTION

[0037] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0038] Furthermore, the accompanying drawings are merely illustrative diagrams of embodiments of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0039] This example embodiment first provides a running device for a treadmill, referring to... Figure 1-7 As shown, the running device includes: a running belt 100, two oppositely arranged side frames 200, a folding mechanism 300, and a transmission mechanism 400.

[0040] Specifically, the running belt 100 includes multiple strip-shaped rigid members 101, with a first gap between adjacent strip-shaped rigid members 101. Adjacent strip-shaped rigid members 101 are not connected, and the first gap provides sufficient space for folding the running belt 100. The shapes of the two opposite long sides of the strip-shaped rigid members 101 can be inclined planes or ">" shaped surfaces, but are not limited to these. The upper surface of the strip-shaped rigid members 101 can be provided with multiple protrusions for anti-slip purposes; the shapes of the protrusions can be circular, rectangular, triangular, rhomboid, etc., but are not limited to these. Furthermore, the material of the strip-shaped rigid members 101 can be steel plate, plastic steel, etc., but is not limited to these.

[0041] The two side frames 200 are disposed on both sides of the running belt 100. Each side frame 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 fixedly connected. The abutting between them or the second gap is provided to provide the structure or space required for folding. When folding is required, it can be done by folding the second frame 202. The folding process will be explained in more detail later.

[0042] It should be noted that a second lateral support 700 can be provided at the bottom of the first frame 201 and the second frame 202. There can be multiple second lateral supports 700, specifically located at the abutment of the first frame 201 and the second frame 202, below the second gap, in the middle of the first frame 201, or at the end of the first frame 201 away from the second frame 202. The second lateral supports 700 support the first frame 201 and the second frame 202. Furthermore, the second lateral support 700 can be a plate or a support block, etc., and a foot is provided below the second lateral support 700 to support 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 respect to the shaft 301. The shaft 301 and the first frame 201 are either fixedly or non-fixedly connected. For example, the shaft 301 can be fixedly connected to the first frame 201 by bolts or other connecting members, while 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 that of 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 non-fixed), while the other end of the connecting member is fixedly connected to the first frame 201.

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

[0046] The shaft 301 can be a pin, a rotating shaft, etc. The shaft 301 and the first frame 201 are connected by a sleeve 303. The sleeve 303 is partially sleeved on the shaft 301 and is fixedly connected to the first frame 201.

[0047] In this embodiment, the first frame 201 and the socket 303 are fixedly connected, and the socket 303 is sleeved on the shaft 301. The rotating member 302 is also sleeved on the shaft 301, and the rotating member 302 is fixedly connected to the second frame 202. Thus, when a rotational force is applied to the second frame 202, the second frame 202 can rotate around the shaft 301, thereby achieving folding of the second frame 202. Furthermore, it should be noted that both the rotating member 302 and the socket 303 can be sleeved on the shaft 301. Specifically, the pin can be inserted into the rotating member 302 and the socket 303. Based on this, limiting elements, such as limiting clips or limiting blocks, can be provided at both ends of the pin to prevent the pin from detaching from the rotating member 302 and the socket 303.

[0048] It should be noted that the shaft 301 can be located on the upper surface of the side frame 200 or above the side frame 200. When located above the side frame 200, it can be supported by a support member. Typically, the height of the shaft 301's axis is the same as the height of the running belt 100, or the height of the shaft 301 is higher than the height of the running belt 100. This arrangement allows the running belt 100 to rotate around the shaft 301 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 inside 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 simultaneously.

[0051] It is important to note that when the second frame 202 is folded, the running belt 100 and the annular flexible belt 401 are folded simultaneously.

[0052] In this embodiment, the running belt 100 is configured as multiple rigid strips 101, connected by a ring-shaped flexible belt 401, eliminating the need for the running board structure in traditional treadmills. The side frame 200 is configured as a first frame 201 and a second frame 202 that are not fixedly connected. Then, under the action of the folding mechanism 300, the second frame 202, the ring-shaped flexible belt 401, and the running belt 100 are folded together. The folded running device saves storage space and is easy to store and transport. This application overcomes the discontinuity caused by the presence of the running board in traditional technology, making the runner's foot feel more comfortable. It also eliminates the need for a multi-layered structure used with the running board, making it easier to fold and use.

[0053] Based on the above embodiments, please refer to Figure 5 Optionally, in some embodiments, the rotating member 302 includes two sleeve portions and one connecting portion. The two sleeve portions and the connecting portion are fixedly connected. 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 enable the sleeve and rotation between the rotating member 302 and the shaft member 301, while the connecting portion enables the fixed connection between the rotating member 302 and the second frame 202. This allows the second frame 202 to rotate under the rotation of the rotating member 302, thereby achieving the folding of the second frame 202. Please refer to the schematic diagram of the folded structure of the running device. 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 support members 600 for supporting the running belt 100 and the annular flexible belt 401.

[0055] For details, please refer to Figure 3 and Figure 4 A third gap (providing folding space) exists between the two support plates 500. Each support plate 500 is provided with multiple first guide wheels 501 and multiple 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 [reference needed]. Figure 6The inner surface of the annular flexible belt 401 has an annular protrusion 4011. The first guide wheel 501 contacts the non-annular protrusion of the annular flexible belt 401, and the second guide wheel 502 contacts the annular protrusion 4011 of the annular flexible belt 401. The first guide wheel 501 and the second guide wheel 502 can be arranged such that a first guide wheel 501 is placed every three or four second guide wheels 502. The first guide wheel 501 and the second guide wheel 502 support and guide the non-protrusion and the annular protrusion 4011 of the annular flexible belt 401, thereby enabling the running belt 100 to move stably.

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

[0057] It is understood that the support plate 500, the first frame 201, and the second frame 202 are respectively fixedly connected to the first transverse support member 600. Specifically, one end of the first transverse support member 600 is fixedly connected to the support plate 500, and the other end is fixedly connected to the side frame 200, thereby achieving support for the running belt 100 and the annular flexible belt 401. The shaft member 301 is located above the abutment of the first frame 201 and the second frame 202 or above the second gap.

[0058] Optionally, in some embodiments, please refer to Figure 6 The annular flexible belt 401 has an engagement portion 4012 on its outer periphery of the annular protrusion 4011.

[0059] Please refer to Figure 2 and Figure 7 The power assembly 402 includes a motor 4021, a drive roller 4022, and a driven roller 4023. Both the drive roller 4022 and the driven roller 4023 are provided with teeth 4024. A meshing part 4012 engages with the teeth 4024. The drive roller 4022 is connected to the motor 4021. The rotation of the motor 4021 drives the drive roller 4022 and the driven roller 4023 to rotate, thereby causing the annular flexible belt 401 and the running belt 100 to move or rotate. The meshing of the meshing part 4012 and the teeth 4024 prevents the annular flexible belt 401 from detaching from the drive roller 4022 and the driven roller 4023, making the running belt 100 run more safely, stably, and smoothly, thus ensuring the user's safety while running.

[0060] Optionally, in some embodiments, there are two annular flexible belts 401, which are respectively disposed at both ends of the driving roller 4022 and the driven roller 4023. The annular flexible belts 401 are disposed on both sides of the rollers, which can make the running belt 100 run more balanced and stable.

[0062] In this embodiment, the beneficial effects of the treadmill with the running device are the same as those described above, and will not be repeated here.

[0063] Optionally, in some embodiments, the treadmill further includes a handrail mechanism (not shown in the figure), which is fixedly or rotatably connected to the running device. The handrail mechanism can also be configured as a foldable structure, allowing the treadmill to be folded to the maximum extent, saving storage space and facilitating transportation.

[0064] It should be understood that in the above embodiments, a front frame 800 can be provided in front of the running belt 100. The front frame 800 and the side frame 200 are fixedly connected to support other parts of the running device.
