[0037] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0038] See also Figures 1-12 A treadmill includes a treadmill main frame 1, a treadmill sub-frame 2 and a drive unit 3.

[0039] The front and rear ends of the treadmill main frame 1 are respectively rotatably connected to the active roller 11 and the driven roller 12. A running belt 13 is wound around the active roller 11 and the driven roller 12. The active roller 11 is connected to the second drive motor 15 fixed to the treadmill sub-frame 2 through a belt 14 or a chain, thereby driving the running belt 13 to circulate. Of course, the structure of the running board and other structures under the running belt 13 can refer to the existing design.

[0040] In this embodiment, brackets 4 are fixed on the left and right sides of the front end of the treadmill main frame 1 respectively. The brackets 4 can be specifically fixed on the outer side of the front end of the treadmill main frame 1, and the inner side of the front end of the treadmill main frame 1 is used for the installation of the active roller 11 so that the two are isolated from each other and do not interfere with each other.

[0041] A first connecting shaft 41 is fixedly provided on the bracket 4 . As one option, the first connecting shaft 41 and the bracket 4 are integrally formed.

[0042] The first connecting shaft 41 extends horizontally toward the outside of the treadmill main frame 1. A rolling unit 5 is mounted on the first connecting shaft 41. The rolling unit 5 is a gear or a roller. In this embodiment, gears are specifically selected, that is, corresponding gears are provided on the left and right sides of the front end of the treadmill main frame 1.

[0043] The rolling unit 5 has a mounting hole in the middle thereof that matches the first connecting shaft 41 , so that the rolling unit 5 is assembled on the first connecting shaft 41 and can rotate on the first connecting shaft 41 .

[0044] The treadmill sub-frame 2 has a first state in which it is arranged in front of the treadmill main frame 1 and a second state in which it is arranged below the treadmill main frame 1 to elevate the treadmill platform. Figure 1 As shown, the treadmill platform is in a horizontal state, which is used for running exercises on flat ground; the second state is as shown in FIG. Figure 2 、 Figure 12 As shown, the treadmill platform is in an inclined state and is used for climbing exercise.

[0045] In this embodiment, the treadmill sub-frame 2 includes a base plate 21 and two side plates 22 fixed at both ends of the base plate 21. Corresponding arc tracks 6 are fixed on the inner side walls of the two side plates 22 respectively. The arc tracks 6 are used to cooperate with the rolling unit 5 so that the rolling unit 5 moves along the track set by the arc tracks 6.

[0046] As described above, the rolling unit 5 is preferably a gear, and correspondingly, the outer wall of the arc track 6 has a convex tooth 61 that meshes with the gear, and the two cooperate as shown in FIG. Figure 5 、 Figure 7 、 Figure 8 and Figure 12As shown, in this embodiment, the protruding teeth 61 are arranged in an arc shape on the arc track 6, that is, the moving path of the rolling unit 5 on the arc track 6 is an arc shape. Of course, the arc track 6 can also be designed as an arc shape as a whole.

[0047] In order to make the connection between the treadmill main frame 1 and the treadmill sub-frame 2 more stable and firm, in this embodiment, a second connecting shaft 23 is fixedly provided on the side plate 22 of the treadmill sub-frame 2. The second connecting shaft 23 is installed at the center of the convex teeth 61 arranged in a circular arc shape. A connecting bar 7 is rotatably connected to the second connecting shaft 23 so that the rolling unit 5 and the movable path of the connecting bar are concentric.

[0048] Specifically, one end of the connecting bar 7 is rotatably connected to the second connecting shaft 23, and the other end is rotatably connected to the first connecting shaft 41. As one option, one end of the connecting bar 7 and the first connecting shaft 41 can be specifically arranged between the rolling unit 5 and the bracket 4, such as Figure 8 shown.

[0049] The cooperation between the rolling unit 5 and the arc track 6 defines the moving path of the front end of the treadmill main frame 1 , and the lifting action of the treadmill depends on the drive of the drive unit 3 .

[0050] Specifically, the drive unit 3 includes a first drive motor 31, a screw 32 and a sleeve 33. The first drive motor 31 is rotatably connected to the treadmill sub-frame 2. One end of the screw 32 is transmission-connected to the first drive motor 31, and the other end is passed through the sleeve 33 and threadedly connected to the sleeve 33. The sleeve 33 is rotatably connected to the treadmill main frame 1.

[0051] The sleeve 33 is a screw sleeve structure, one end of which is open and has a hollow cavity inside that cooperates with the screw 32, and an internal thread that cooperates with the thread of the screw 32 is provided on the inner wall of the hollow cavity. When the screw 32 rotates forward, the thread cooperation can make one end of the screw 32 move into the sleeve 33, that is, the screw 32 and the sleeve 33 shrink relatively, and the overall size of the screw 32 and the sleeve 33 is shortened; when the screw 32 reverses, the screw 32 and the sleeve 33 extend relatively, and the overall size of the screw 32 and the sleeve 33 becomes longer. The forward and reverse rotation of the screw 32 is controlled by the forward and reverse rotation of the first drive motor 31.

[0052] As a further option, a reduction mechanism is connected to the output end of the first drive motor 31, and the reduction mechanism is assembled into one with the first drive motor 31 to form a drive body. The drive body can directly select the reduction motor, or add a related reduction structure in the existing technology to the motor. One end of the screw 32 is inserted into the reduction mechanism and is connected to the reduction mechanism to increase the output torque.

[0053] As one of the embodiments, a first pivot seat 24 is fixed on the treadmill sub-frame 2, and a second pivot seat 16 is fixed on the bottom cross bar of the treadmill main frame 1. The driving body is rotatably assembled on the first pivot seat 24, and the outer end of the sleeve 33 is rotatably assembled on the second pivot seat 16.

[0054] When the treadmill needs to be lifted, the first drive motor 31 is started to rotate forward to drive the screw 32 to rotate. Depending on the threaded fit between the screw 32 and the sleeve 33, the two are relatively contracted. During this action, the rolling unit 5 climbs along the trajectory set by the arc track 6, and the treadmill sub-frame 2 gradually moves under the head of the treadmill main frame 1. The head of the treadmill main frame 1 is gradually lifted. After lifting, Figure 12 As shown; and when you need to restore the treadmill to Figure 1 In the horizontal state shown, it is only necessary to control the first drive motor 31 to rotate in the reverse direction, so that the screw 32 and the sleeve 33 are relatively extended, and the treadmill main frame 1 and the treadmill auxiliary frame 2 are restored to their original state.

[0055] In order to improve the stability of the treadmill's shape change, in this embodiment, when the treadmill sub-frame 2 is in the first state, the bottom plate 21 of the treadmill sub-frame 2 is located below the rolling unit 5. As a further option, at least a portion of the bottom plate 21 is located directly below the rolling unit 5.

[0056] As one option, a baffle 25 may be further provided at the front of the treadmill sub-frame 2. Figure 9 As shown, the left and right ends of the baffle 25 are respectively fixedly connected to the left and right side plates 22, and the lower end is fixedly connected to the bottom plate 21. The baffle 25, the two side plates 22 and the bottom plate 21 are connected into one body.

[0057] In this embodiment, a treadmill head shell is also provided, which is used to cover the treadmill head structure, including two states: raised and non-raised.

[0058] Specifically, the treadmill head shell includes a main shell 81 and a front side panel 82, wherein the main shell 81 includes a top side panel 811 and two side panels 812 arranged on the left and right sides of the top side panel 811, and has an opening 813 at the front, and the front side panel 82 is assembled at the opening 813.

[0059] In this embodiment, the lower end of the front side plate 82 is rotatably connected to the front lower end of the treadmill sub-frame 2, and the upper end of the front side plate 82 is rotatably connected to the main shell 81. As one of the implementation methods, the upper end of the front side plate 82 is specifically rotatably connected to the upper end position of the opening 813. For example, the extended edges 821 at both ends of the front side plate 82 are arranged at the two side panels 812 of the main shell 81, and can be arranged to fit each other. The upper end of the extended edge 821 is rotatably connected to the corresponding position of the side panel 812, which is located at the upper end of the opening 813.

[0060] In this embodiment, the rear end of the main shell 81 is rotatably connected to the front end of the treadmill main frame 1. As one implementation method, the rear end of the main shell 81 is rotatably connected to the first connecting shaft 41, and the rotating connection is concentric with the rolling unit 5.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
