[0034] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0035] Refer to Figures 1-11 , a lifting structure of a double-sided treadmill, including a treadmill main frame 1, a connecting member 2, and a lifting unit 3.

[0036] For the treadmill main frame 1 and the components such as the running board and running belt provided on the treadmill main frame 1, reference can be made to the existing design or the patent application filed by the applicant: 2024215907326.

[0037] The connecting member 2 is fixedly provided on the side wall of the treadmill main frame 1. As one of the embodiments, the connecting member 2 includes a first part 21 and a second part 22. As shown in Figure 4 , Figure 5 , wherein the second part 22 is fixedly provided on the treadmill main frame 1, and the first part 21 and the second part 22 can be integrally formed, such as by bending to form the first part.

[0038] As another embodiment, the connecting member 2 only has a first part, and the inner end of the first part is fixedly provided on the side wall of the treadmill main body frame 1, as shown in Figure 6 .

[0039] Regardless of which of the above implementation manners is adopted, the structure of the first part 21 of the connecting member 2 is the same or similar. In this embodiment, the first part 21 specifically extends laterally towards the main frame body 1 of the treadmill. The first part 21 is used for limiting the lifting unit 3. The form of lateral extension enables the movement range of the lifting unit 3 to be on the side of the main frame body 1 of the treadmill, and the components of the main frame body 1 of the treadmill will not interfere with the movement of the lifting unit 3, so that it can be applied to both the front and back sides of the treadmill.

[0040] Further, the upper part of the first part 21 is bent forward towards the main frame body 1 of the treadmill to form a first limiting wall 211, and the lower part of the first part 21 is bent forward towards the main frame body 1 of the treadmill to form a second limiting wall 212. The first limiting wall 211 and the second limiting wall 212 are connected by a curved surface, and this curved surface faces the lifting unit 3.

[0041] Specifically, taking the middle part of the first part 21 as the starting point, its upper part is bent into an inclined state, and the bending direction is from the rear end to the front end of the main frame body 1 of the treadmill; its lower part is also bent into an inclined state, and the bending direction is from the rear end to the front end of the main frame body 1 of the treadmill.

[0042] The curved surface part is the middle part 23 of the first part 21. The curved surface design can improve the rotation smoothness of the lifting unit 3 and prevent the two from getting stuck; the first limiting wall 211 and the second limiting wall 212 are used for the limiting function when the lifting unit 3 is in the lifted state. For specific details, please refer to the description of the lifting unit below.

[0043] As one option, the first limiting wall 211 and the second limiting wall 212 are symmetrically arranged.

[0044] For the lifting unit 3, it is rotatably arranged on the connecting member 2 or the main frame body 1 of the treadmill, and has a first state of abutting against the first limiting wall 211 to lift the treadmill with the front side facing up, a second state of abutting against the second limiting wall 212 to lift the treadmill with the back side facing up, and a third state of being folded, as Figure 1 、 Figure 2 shown, which is a schematic diagram of the lifting unit 3 in the first state; as Figure 7 、 Figure 8 shown, which is a schematic diagram of the lifting unit 3 in the third state; as Figure 9 、 Figure 10 shown, which is a schematic diagram of the lifting unit 3 in the second state.

[0045] When the lifting unit 3 is in the first state, its side wall fits against the first limiting wall 211. At this time, the whole lifting unit 3 is also in an inclined state, specifically inclined towards the front end direction of the main frame body 1 of the treadmill. Limited by the first limiting wall 211, it can only rotate towards the rear end direction of the main frame body 1 of the treadmill. Therefore, it can stably play the role of lifting and supporting.

[0046] When the lifting unit 3 is in the second state, its side wall fits against the second limiting wall 212. At this time, the entire lifting unit 3 is also in an inclined state, specifically inclined towards the front end of the main frame body 1 of the treadmill. Limited by the second limiting wall 212, it can only rotate towards the rear end of the main frame body 1 of the treadmill. Therefore, it can stably play the role of lifting and supporting.

[0047] When the lifting unit 3 is in the third state, its lower end leaves the ground and is horizontally arranged on the side wall of the main frame body 1 of the treadmill, in a horizontal or nearly horizontal state. As an option, the width of the lifting unit 3 can be less than or equal to the width of the side rod of the main frame body 1 of the treadmill, or less than the height of the side of the treadmill after installing the outer shell, so that the height of the lifting unit 3 will not exceed the height of the treadmill itself after folding, making the whole more coordinated and beautiful.

[0048] As mentioned above, the connecting member 2 has a curved surface portion. Correspondingly, the outer wall 31 at the upper end of the lifting unit 3 is semi-circular. During the process of the lifting unit 3 switching between being applicable to the front of the treadmill and being applicable to the back of the treadmill, its semi-circular outer wall 31 at the upper end needs to contact or approach the curved surface portion. By designing these two portions into curved surfaces, the smoothness of the rotation of the lifting unit 3 can be ensured and jamming can be prevented.

[0049] In this embodiment, the center of the semi-circular outer wall 31 at the upper end of the lifting unit 3 is concentric with the rotation center point of the lifting unit 3.

[0050] Of course, the bottom surface 32 at the lower end of the lifting unit 3 for contacting the ground can also be designed as an arc to reduce the friction during the rotation process and improve the smoothness of the state change.

[0051] Regarding the rotation positioning method of the lifting unit 3, in this embodiment, a first through hole is opened on the main frame body 1 of the treadmill. A screw sleeve 4 is inserted through the first through hole, and at least one end of the screw sleeve 4 extends outside the main frame body of the treadmill to form an extension section. A second through hole 24 adapted to the outer surface of the extension section is opened on the connecting member 2 so that it is sleeved on the extension section of the screw sleeve 4.

[0052] A through hole is also opened on the lifting unit 3 to insert a screw rod 5 that is threadedly engaged with the screw sleeve 4 on the lifting unit 3. Specifically, after passing through the second through hole 24, the screw rod 5 is threadedly engaged with the screw sleeve 4, thereby positioning the lifting unit 3 on the main frame body 1 of the treadmill. Allowing the screw rod 5 to pass through is also the main function of the second through hole 24. The form of the sleeve of the connecting member 2 and the extension section does not affect the design of the connecting member being fixed to the main frame body 1 of the treadmill. For example, if the extension section is only inserted through the connecting member 2, the connecting member 2 is still fixed to the main frame body 1 of the treadmill; of course, the screw sleeve 4, the main frame body 1 of the treadmill, and the connecting member 2 can also be fixed together.

[0053] In this embodiment, the rotation center point of the lifting unit 3 is located on the symmetry line L of the first limiting wall 211 and the second limiting wall 212. As Figure 11 shown, to ensure that the lifting unit 3 can reliably cooperate with the corresponding part of the first part 21 of the connecting member after rotation, and can stably support the overall treadmill and the user on the treadmill after lifting.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
