[0051] The directional words such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the specification and claims of the utility model are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional words should not limit the scope of protection claimed by the utility model.

[0052] like Figures 1 to 5 As shown, the foldable treadmill provided by the embodiment of the utility model comprises a treadmill body 1, a pole assembly 2, a storage bracket 3 and a storage platform 4, and the storage platform 4 is detachably arranged on the storage bracket 3. The pole assembly 2 comprises two columns 21 respectively arranged on the left and right sides of the treadmill body 1, and the bottom end of each column 21 is rotatably connected to the front end of the treadmill body 1, and the storage bracket 3 is rotatably connected to the top ends of the two columns 21 at the same time, so that the pole assembly 2 and the storage bracket 3 can both be unfolded and folded.

[0053] The foldable treadmill has an unfolded state and a folded state. Figure 1 and Figure 2 As shown, when the foldable treadmill is in the unfolded state, the upright pole assembly 2 is maintained in a standing state (that is, the upright pole assembly 2 is in a vertical state, or the upright pole assembly 2 is in an inclined upright state at a certain angle to the vertical direction), the storage bracket 3 is maintained in a horizontal state and is used to place the storage table 4 (of course, when there is no need to place items, the storage table 4 may not be placed on the storage bracket 3), and a certain angle is formed between the storage bracket 3 and the upright pole assembly 2; Figure 3 As shown, when the foldable treadmill is in the folded state, the storage platform 4 is removed from the storage bracket 3, and the storage bracket 3 is rotated to be in the same plane as the upright assembly 2 (that is, the plane where the storage bracket 3 is located is in the same plane as the plane where the upright assembly 2 is located), and the storage bracket 3 and the upright assembly 2 are both stored to the side of the treadmill body 1 and can be maintained in the folded state.

[0054] The foldable treadmill provided in this embodiment is provided with a storage bracket 3 and a storage platform 4. The storage bracket 3 is rotatably connected to the upright assembly 2, and the storage platform 4 is detachably arranged on the storage bracket 3. When the foldable treadmill is unfolded, the upright assembly 2 is rotated to remain in a standing state, and the storage bracket 3 is rotated to a horizontal state, so that the foldable treadmill is in an unfolded state. At this time, the storage platform 4 can be placed on the storage platform 4, and the user can put items such as mobile phones and tablets (of course, water cups, keys, etc. can also be portable items) Items) are placed on the storage table 4 to realize the storage function of the treadmill; when folding the foldable treadmill, the storage table 4 is first removed from the storage bracket 3, and then the storage bracket 3 and the upright assembly 2 are rotated to the side of the treadmill body 1, so that the storage bracket 3 and the upright assembly 2 are stored to realize the folding and storage function of the treadmill; and in the folding process, the storage bracket 3 is rotated to be in the same plane as the upright assembly 2, thereby reducing the space occupied by the storage bracket 3 in the folded state and facilitating folding. The foldable treadmill is equipped with a storage table 4, which can hold items such as mobile phones and tablets, and has a folding and storage function, which is convenient for users to use.

[0055] It should be noted that some existing foldable treadmills are also provided with a mobile phone holder, but in order to facilitate the folding of the mobile phone holder, the mobile phone holder is generally set very small and is only used to temporarily place the mobile phone, but cannot place other items or large items. However, this embodiment provides a storage holder 3 and a storage table 4, and the storage table 4 can place various different items or large items, thereby improving the functionality of the foldable treadmill and facilitating the use of users.

[0057] like Figure 1 and Figure 2 As shown, when the foldable treadmill is in the unfolded state, the storage bracket 3 is in a horizontal state, the top of the column 21 is tilted backward compared to its bottom, and the storage bracket 3, the upright assembly 2 and the treadmill body 1 form a Z-shaped structure (that is, the storage bracket 3 is located at the front side of the top of the upright assembly 2); such a configuration can reduce the storage bracket 3 and the storage platform 4 occupying the upper space of the treadmill body 1, improve the space utilization rate of the treadmill body 1, and facilitate users to run on the treadmill body 1. Figure 3As shown, when the foldable treadmill is in a folded state, the storage bracket 3 is located at the rear side of the upright assembly 2, the cross bar 31 is stored to the rear side of the treadmill body 1 (i.e., the cross bar 31 is located at the rear side of the treadmill body 1 and close to the rear side wall of the treadmill body 1), and the two uprights 21 and the two side bars 32 are respectively stored to the left and right sides of the treadmill body 1 (i.e., one of the uprights 21 and one of the side bars 32 is located on the left side of the treadmill body 1 and close to the left side wall of the treadmill body 1, and the other uprights 21 and the other side bars 32 are located on the right side of the treadmill body 1 and close to the right side wall of the treadmill body 1); such a configuration can facilitate the folding of the storage bracket 3 and the upright assembly 2, and minimize the space occupied by the storage bracket 3 and the upright assembly 2 when in the folded state.

When the storage platform 4 is placed on the storage bracket 3, the cross bar 31 is locked in the locking groove 401, and the hooks 402 on the left and right sides are respectively hooked on the two side bars 32, so that the storage platform 4 is fixed on the storage bracket 3; when the storage platform 4 is removed from the storage bracket 3, the hooks 402 on the left and right sides are first rotated to disengage the hooks 402 from the side bars 32, and then the storage platform 4 can be removed from the storage bracket 3. Of course, in other embodiments, the locking mechanism 40 can also be other locking structures.

[0061] As another embodiment, the storage table 4 and the storage bracket 3 are fixed by magnetic attraction to achieve a detachable connection between the two. Specifically, a magnetic block (not shown in the figure, such as a magnetic steel, a magnet, etc.) can be set on the storage table 4, and the storage bracket 3 is made of a metal material that can be attracted to the magnetic block, and the magnetic block and the storage bracket 3 are attracted to achieve the fixing of the storage table 4 and the storage bracket 3; or, a first magnetic block is set on the storage table 4, and a second magnetic block is set on the storage bracket 3, and the first magnetic block and the second magnetic block are attracted to achieve the fixing of the storage table 4 and the storage bracket 3.

[0064] like Figures 6 to 9 As shown, as an embodiment, the foldable treadmill also includes a hinge assembly 500, and the bottom end of the column 21 is rotatably connected to the treadmill body 1 through the hinge assembly 500; the hinge assembly 500 includes a rotating assembly 5 and a fixed assembly 6, the bottom end of the column 21 is fixedly connected to the rotating assembly 5, the fixed assembly 6 is fixedly connected to the treadmill body 1, the rotating assembly 5 is rotatably connected to the fixed assembly 6, and the rotating assembly 5 can rotate relative to the fixed assembly 6, thereby realizing the rotational connection between the column 21 and the treadmill body 1.

[0065] like Figures 9 to 13b As shown, as an embodiment, a first limiting structure 53 is provided on the rotating component 5, and a second limiting structure 64 is provided on the fixed component 6. The second limiting structure 64 is used to cooperate with the first limiting structure 53 to stop the rotating component 5 so that the rotating component 5 cannot continue to rotate after rotating to a specific position, so as to limit the column 21 when the column 21 is in an expanded state or a folded state, preventing the column 21 from continuing to rotate, so that the column 21 can remain in the expanded state or the folded state.

[0066] like Figures 9 to 13bAs shown, as an embodiment, the hinge assembly 500 further includes a limit switch 7 for locking and unlocking the rotating assembly 5, and the limit switch 7 is movably connected to the fixing assembly 6. The limit switch 7 can be engaged with the rotating assembly 5, so that the rotating assembly 5 is locked, so as to lock the column 21 in the unfolded state, and prevent the column 21 from rotating and folding by itself during the user's movement; when the limit switch 7 is turned on, the rotating assembly 5 is unlocked, and the rotating assembly 5 can continue to rotate, so that the column 21 can rotate and fold.

[0067] like Figures 8 to 13b As shown, as an embodiment, the fixing assembly 6 includes a hollow base 61 and a first shaft 62 fixed to the base 61, one end of the first shaft 62 is located outside the base 61 and fixedly connected to the treadmill body 1, and the other end of the first shaft 62 extends into the base 61;

The limiting shaft 52 is located in the base 61 and is sleeved on the first shaft 62. The limiting shaft 52 is fixedly connected to the column 21 and can rotate with the column 21.

[0069] The first limiting structure 53 is arranged on the limiting shaft 52, and the second limiting structure 64 is arranged on the inner wall of the base 61. The second limiting structure 64 is located on the rotation path of the first limiting structure 53, so that when the limiting shaft 52 rotates with the column 21, the first limiting structure 53 on the limiting shaft 52 can stop the second limiting structure 64 on the inner wall of the base 61, so as to limit the column 21 when the column 21 is in the unfolded state or the folded state.

[0070] like Figures 10 to 12 As shown, as an embodiment, the first shaft 62 and the second shaft 51 are both cylindrical structures, and the second shaft 51 is located on one side of the first shaft 62 along the axial direction of the second shaft 51. The first shaft 62 is fixedly connected to the pin 63, and the second shaft 51 is rotatably connected to the pin 63, thereby realizing the rotatable connection between the second shaft 51 and the first shaft 62.

[0075] like Figures 9 to 12 As shown, as an embodiment, a mounting opening 611 is provided on the side of the base 61 facing the second shaft 51, and the mounting opening 611 is used to install the limiting shaft 52 and other components into the base 61. A cover plate 65 fixed to the base 61 is provided at the mounting opening 611 (specifically, the cover plate 65 and the base 61 can be fixed by screwing), so as to seal the base 61 and prevent the parts inside the base 61 from loosening or falling out.

[0076] like Figures 8 to 11 As shown, as an embodiment, the limiting shaft 52 is fixedly connected to the column 21 through a connecting rod 55, one end of the connecting rod 55 is fixed to the column 21, and the other end of the connecting rod 55 is fixed to the limiting shaft 52, so that the limiting shaft 52 can rotate with the column 21. Specifically, in this embodiment, there are two connecting rods 55, one end of the two connecting rods 55 is connected to the first limiting portion 531 and the second limiting portion 532 respectively, and the other ends of the two connecting rods 55 are connected to the column 21 (specifically, the column 21 is provided with a hole for the connecting rod 55 to be inserted).

The shaft 631 includes a first rod portion 631a and a second rod portion 631b connected to each other. The first rod portion 631a is located between the stop portion 632 and the second rod portion 631b. The outer diameter of the first rod portion 631a is greater than the outer diameter of the second rod portion 631b.
