[0002] The treadmill is a very popular indoor aerobic fitness device because it can simulate natural walking or running, is not limited by weather and location, is very popular with fitness enthusiasts, and is widely used at home, in gyms and other places.

[0003] The current mainstream of household treadmills on the market typically comprises a core structure consisting of a long, strip-like running frame to support the user for running or walking, a stand at the front of the running frame, and a support frame on the floor. To accommodate limited home living space, most products are designed with a folding mechanism, which usually involves lifting the entire running deck section around the pivot axis at the front end to transform it from a horizontal usage state to a near-vertical folding state. However, this traditional vertical folding method has significant drawbacks: Excessive vertical space occupied: Even when the platform is raised vertically, the overall height of the device in its folded state is considerable due to its length, which is almost entirely converted into its height when folded. This can create a noticeable vertical space barrier in small homes, low storage areas, or rooms with limited ceiling height, resulting in significant "vertical space wastage." The device can often only be placed against a wall, which not only affects its aesthetics but also easily hinders daily activities.

[0004] Furthermore, the entire shape of the vertically folded treadmill is thin and has a high center of gravity; its volume is still large, and it is difficult to move and find a suitable storage place. CONTENTS OF THE PRESENT USE SAMPLE

[0005] Regarding the shortcomings of the existing technology, the utility model offers a folding treadmill, whereby a folded reduction of the folding treadmill in the longitudinal direction is achieved by folding the running frame and running plates in order to reduce the storage space and facilitate use.

[0007] In the above solution, preferably, the compensation mat is provided on a surface at one end of the front running plate facing the rear running plate and extends to the other end, wherein an upper surface of the compensation mat is higher than a surface of the rear running plate after the front running plate and the rear running plate have unfolded.

[0008] In the above solution, preferably, the compensation mat is provided on a surface at one end of the rear running plate facing the front running plate and extends to the other end, wherein an upper surface of the compensation mat is higher than a surface of the front running plate after the front running plate and the rear running plate have unfolded.

[0009] In the above solution, preferably, a buffer mat is provided between the connected ends after unfolding the front running plate and the rear running plate; wherein the buffer mat is provided on the front running plate or the rear running plate. In the above solution, preferably, the folding treadmill comprises at least one rotating part which is provided between the front running frame and the rear running frame; wherein the rotating part changes an angle between the front running frame and the rear running frame in order to achieve a relative folding and unfolding between the running frames.

[0010] In the above solution, preferably, the rotating part comprises a first positioning element and a second positioning element, wherein the first positioning element and the second positioning element are respectively arranged on the front running frame and the rear running frame; wherein a rotatable connection is established between the first positioning element and the second positioning element via a rotating shaft.

[0011] In the above solution, preferably, one axis of the rotating shaft is flush with the end faces of the front running frame and the rear running frame in the deployed state or higher than these end faces; wherein the rotating shaft is provided on a side where the angle between the front running frame and the rear running frame decreases during relative folding by the rotating part.

[0012] In the above solution, preferably, a locking element is arranged between the front running frame and the rear running frame for the relative fastening of the two after unfolding; wherein the locking part comprises a first locking element on the front running frame and a second locking element on the rear running frame; where, after unfolding the rear running frame relative to the front running frame, the two are locked together by strapping the second locking element to the first locking element.

[0024] The rotating shaft 303 is located on a side where the angle between the front running frame 1 and the rear running frame 2 decreases when the front running frame 1 and the rear running frame 2 are folded relative to each other by the rotating part 3, for example Fig. Taking 3 as an example, the pivot shaft 303 is located above the front running frame and the rear running frame 2.

[0025] The upper surface of the front running plate 101 and / or the rear running plate 201 is provided with a compensation mat 4. In particular, the compensation mat 4 is provided on the upper surface of a side facing the running belt; that is, the compensation mat 4 can be provided separately on the front running plate 101 or the rear running plate 201, or simultaneously cover the front running plate 101 and the rear running plate 201. In this embodiment, the compensation mat 4 on the rear running plate 201 is taken as an example, as shown in Fig. 7 shown;

[0026] The compensating mat 4 is a flexible mat whose lower surface is firmly bonded to the front running plate 101 or the rear running plate 201 by adhesive, and whose upper surface is smooth. When the compensating mat 4 is placed on the upper surface of the rear running plate 201, one end of the compensating mat 4 is flush with the end face of the rear running plate 201 facing the front running plate 101, and the other end of the compensating mat 4 extends rearward from the end of the front running plate 101, and its length can extend over part or all of the surface of the rear running plate 201.

Its length can extend over part or all of the surface of the front running plate 101. The surface of the compensation mat 4 is higher than the surface of the rear running plate 201, and the height difference can be adjusted between 0.2 mm and 1.5 mm.

[0028] Any drop or resistance that occurs when pedaling at the connection when unfolding the front running plate 101 and the rear running plate 201 is compensated or overcome by the compensation mat 4.

[0029] After the front running plate 101 and the rear running plate 201 have been unfolded, a buffer mat 401 is provided between the adjoining ends. The buffer mat 401 is provided on the front running plate 101 or on the rear running plate 201. In this embodiment, the buffer mat 401 is shown on the front running plate 101 as an example. The section of the buffer mat 401 is a right-angled section. One lateral right-angled surface of the buffer mat 401 rests against the end face of one side of the front running plate 101 facing the rear running plate 201 in order to compensate for a gap that arises when the front running plate 101 and the rear running plate 201 are unfolded. The other lateral right-angled surface of the buffer mat 401 extends towards the end face of a side facing away from the running belt 7 to allow for fastening.When the buffer mat 401 is placed on the rear running plate 201, the setting direction of the buffer mat 401 is a mirror image of the setting direction of the buffer mat 401 on the front running plate 101, i.e. one lateral rectangular surface lies against the end face of the rear running plate 201, and the other lateral rectangular surface extends in the direction of the lower end face of the rear running plate 201.

[0030] The upper end face of the buffer mat 401, located at the junction between the front running plate 101 and the rear running plate 201, may be lower than either the front running plate 101 or the rear running plate 201, or it may be flush with the end face of the aforementioned running plate to form a seamless connection between the front and rear running plates.

A locking element 5 is provided between the front running frame 1 and the rear running frame 2 for the relative fastening of the two after unfolding. The locking element 5 comprises a base 6, a first locking element 501, and a second locking element 502. The base 6 is fastened by a screw to the side face of an end of the front running frame 1 facing the rear running frame 2, as shown in Fig.4 shown, and base 5 is located below the front running plate 101.

[0031] The first locking element 501 is hinged to the base 6 via a pin shaft 601, and the first locking element 501 is pivotable about the pin shaft 601 at a certain angle to match the angle at which the second locking element 502 engages the first locking element 501. The second locking element 502 is welded or bolted to the side surface of an end of the rear running frame 2 facing the front running frame 1. The second locking element 502 is provided at its front end with a locking core 506, which is cylindrical in the vertical direction and has a clamping opening at its junction with the second locking element 502 that is smaller than the outer diameter of the locking core 506.

[0032] The first locking element 501 is provided with a locking hole 503 that fits the locking core 506. The locking hole 503 is provided on both sides with an elastic spring steel wall 505. The locking hole 503 is also a cylindrical hole, the end of which facing away from the base 6 is provided with a transition slot 504. The transition slot 504 extends through the locking hole 503. The locking core 506 can press the elastic wall 505 into the locking hole 503 on both sides and pass through the transition slot 504. Subsequently, the elastic wall 505 is retracted so that its end is firmly inserted into the clamping opening, forming a clamping action between the first locking element 501 and the second locking element 502.

[0033] The end of the elastic wall 505 forms an elastic joint with the base 6 via the pin shaft 601, in which a torsion spring can be installed to further improve the elastic restoring function of the elastic wall 505.

[0034] The front running frame 1 and the rear running frame 2 are each provided with a second running plate on the end faces of the sides facing away from the front running plate 101 and the rear running plate 201, respectively. This second running plate is a massage plate whose surface has several protruding points. When the treadmill unfolds, the second running plate on the front running frame 1 and the second running plate on the rear running frame 2 are connected at their centers; that is, their position is the same as that of the front running plate 101 and the rear running plate 201 when the treadmill is unfolded. The running belt 7 covers the front running plate 101, the rear running plate 201, and the second running plate.When the front running frame 1 and the rear running frame 2 are in the unfolded state and the front running plate 101 and the rear running plate 201 are facing upwards, the treadmill is in the running state; when the second running plate is facing upwards, i.e., when the treadmill is in the folding state, the treadmill as a whole is reversed so that the front running plate 101 and the rear running plate 201 are on a floor-facing side, at this time the treadmill is in the massage state in order to achieve the floor massage effect by walking on the treadmill through the protrusions on the second running plate. Locking / unlocking process:

[0035] Locking: When the rear running frame 2 unfolds into the horizontal position, the locking core 506 slides along the transition slot 504 and pushes the elastic wall 505 outwards, causing it to expand and deform; when the locking core 506 fully enters the locking hole 503, the elastic wall 505 springs back and works together with the clamping opening to achieve a mechanical locking action. Unlocking: The rear running frame 2 is manually lifted upwards relative to the front running frame 1, then turned over by the rotating part 3, the locking core 506 is necessarily pulled out of the locking hole 503 to expand the elastic wall 505 twice, finally the locking core 506 slides out of the locking hole 503 through the transition slot 504 to release the first locking element 501 from the second locking element 502 to complete the unlocking.
