Description

Technical Field

[0001] The invention relates to the technical field of treadmills, and in particular to a treadmill lifting and folding integrated device. Background Art

[0002] With the development and progress of society, people's quality of life is constantly improving, but the number of people suffering from sub-health and obesity is increasing. The reason is that due to the changes in the current social structure, people's lives are tense and busy, and the time for exercise is relatively reduced. In addition, most fitness venues are open-air venues, which are greatly affected by weather factors, making it difficult to stick to fitness. Therefore, indoor fitness exercises have been widely accepted by people. After being introduced to the market as aerobic exercise equipment, treadmills are becoming more and more popular among consumers. It can not only exercise the runner's physique, tolerance and cardiopulmonary function, but also make the runner feel like running on a normal road, achieving the purpose of scientific exercise.

[0003] The frame and the treadmill are the main components of a treadmill. With the continuous development of the industry, in order to facilitate the folding and use of the frame and the treadmill, treadmills in the prior art have been designed with various folding structures. Generally, the rear part of the treadmill is lifted manually for folding, or conversely, the frame is rotated downward and folded onto the treadmill, and then a gas spring is used for limiting the position to fix the folding angle.

[0004] In addition, existing treadmills all have a slope adjustment mechanism that is separate from the folding structure and independent of the folding structure. The slope adjustment mechanism mostly adopts a three-link or two-link mechanism, and the slope is raised and lowered by extending and shortening the lifting motor. At the same time, the lifting slope is limited by the link mechanism.

[0005] As can be seen from the above, the existing folding structure is relatively common, not safe, laborious to use, and takes up space. In addition, there is no design that combines slope adjustment and folding functions, so this case is born. Summary of the invention

DETAILED DESCRIPTION

[0024] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figure 1 The present invention provides a treadmill lifting and folding integrated device, including a frame 1, a first lifting mechanism 2 and a treadmill 3, wherein the first lifting mechanism 2 is installed on the frame 1, the front of the treadmill 3 is connected to the first lifting mechanism 2, and the first lifting mechanism 2 drives the front of the treadmill 3 to lift and lower.

[0026] In one embodiment, the lifting and folding integrated device further includes a control console 4 for controlling the operation of the treadmill and an armrest 6 , wherein the armrest 6 is rotatably connected to the frame 1 .

[0027] The console 4 is provided with a second lifting mechanism 5, and the console 4 is installed on the frame 1 through the second lifting mechanism 5 and performs lifting movement along the frame 1. The first lifting mechanism is electrically connected to the console. It is important that the second lifting mechanism 5 is located on the outside of the first lifting mechanism 2. When folding, the console 4 closes the front of the treadmill 3, so that the folding limit can be achieved. It can be seen that the console of the present invention is not just used as a console, but also used as a limiting structure, so that the console is flexibly used.

[0028] The specific forms of the first lifting mechanism 2 and the second lifting mechanism 5 of the present invention can be various. In this embodiment, a relatively reliable screw transmission structure is adopted:

[0029] The first lifting mechanism 2 includes two treadmill screw rods 21, 22, a synchronization component 23, a first reduction motor 24 and treadmill nuts 25, 26 matched with the treadmill screw rods 21, 22. The treadmill screw rods 21, 22 are vertically installed on both sides of the frame 1, and a synchronization component 23 is provided between the two treadmill screw rods 21, 22 and the first reduction motor 24, and are connected through the synchronization component 23. Treadmill cams 31, 32 are provided on both sides of the front of the treadmill 3. The treadmill nuts 25, 26 are provided with first grooves 251, 261 for placing the treadmill cams 31, 32. The treadmill nuts 25, 26 are matched with the treadmill screw rods 21, 22 to drive the front of the treadmill to move up and down along the treadmill screw rods 21, 22.

[0030] The second lifting mechanism 5 includes two console lead screws 51, 52, two fixing boxes 53, 54, two second reduction motors 55, 56 and two console nuts 57, 58. The fixing boxes 53, 54 are respectively fixed on both sides of the frame 1 and are located on the outside of the first lifting mechanism 2. The console lead screws 51, 52 are vertically installed on the fixing boxes 53, 54. A second reduction motor 55, 56 is connected to each of the console lead screws 51, 52. Console cams (not shown in the figure) are provided on both sides of the console 4. Second grooves 571, 581 for placing the console cams are provided on the console nuts 57, 58. The console nuts 57, 58 are matched with the console lead screws 51, 52 to drive the console 4 to move up and down along the console lead screws 51, 52.

[0031] The bottom of the treadmill screw rods 21, 22 and the console screw rods 51, 52 are respectively provided with a bearing seat assembly, and the bearing seat assembly includes components such as bearings, which mainly play the role of supporting and bearing the treadmill screw rods. The synchronization assembly 23 described in this embodiment specifically includes a synchronization screw rod 231 and synchronization gears 232, 233. The top of the console screw rods 51, 52 is respectively fixed with a synchronization gear 232, 233, and the two synchronization gears 232, 233 are horizontally flush. The two ends of the synchronization screw rod 231 are respectively matched with the synchronization gears 232, 233. The first reduction motor 24 is connected to the synchronization screw rod 231, and the frame 1 is provided with a crossbeam 12 at the position corresponding to the synchronization screw rod 231, and the crossbeam 12 is for placing the synchronization screw rod 231 and the first reduction motor 24. The installation process of this case is as follows: first, fix the two bearing seat assemblies on both sides of the bottom of the frame 1 by bolts, install the treadmill screw rods 21, 22 on the bearing seat assemblies respectively, then place the synchronous screw rod and the first reduction motor on the crossbeam, and connect the synchronous screw rod to the treadmill screw rod according to the above installation method, then put the treadmill nuts 25, 26 on the treadmill screw rods 21, 22 to ensure that the treadmill nuts 25, 26 on both sides are kept at the same height, and then hang the treadmill 3 in the first grooves 251, 261 of the treadmill nuts through the treadmill convex shafts 31, 32 on both sides of the front, so as to obtain the connection between the front part of the treadmill and the first lifting mechanism 2; secondly, first install the second lifting mechanism 5 and the control console 4 together, and then fix the fixing boxes 53, 54 of the second lifting mechanism 5 on the frame 1 outside the first lifting mechanism 2, so as to complete the installation of the control console 4 and the frame 1; finally, install the handrails 6 on both sides of the frame 1.

[0032] The working process of this case is as follows: the first reduction motor 24 is started, and the synchronization component 3 is driven to synchronously rotate the two treadmill screw rods 21, 22 first, and the treadmill nuts 25, 26 matched with the two treadmill screw rods 21, 22 drive the front of the treadmill 3 to be lifted steadily; during this lifting process, the second reduction motor 55, 56 is started again, the console screw rods 51, 52 rotate, and the console nuts 57, 58 matched with the console screw rods move up, driving the console 4 to move up. When the slope of the treadmill 3 reaches the maximum value, the treadmill 3 is folded. Finally, the second reduction motor 24 is reversed, and the console 4 moves down, so that the console 4 closes the front of the treadmill 3, restricting the treadmill 3 from being lowered, and the handrail 6 is rotated downward to move close to the frame 1, so that the handrail 6 is folded.

[0033] It should be noted that a synchronization structure of the analog and synchronization components can be set between the control console screws, which can be designed according to actual needs and will not be described in detail in this case.

[0034] like Figure 3 and Figure 4As shown in the figure, when the front part of the treadmill is lifted and the slope increases, the front part of the treadmill drives the rear part of the treadmill to move toward the frame 1, and the treadmill 3 as a whole is folded relative to the frame 1. At this time, the treadmill 3 is in a folded state. When the front part of the treadmill 3 is lowered, it drives the rear part of the treadmill away from the frame 1, and the treadmill 3 as a whole is stretched and laid flat relative to the frame 1. At this time, the treadmill 3 can be used for running, as shown in the figure. Figure 2 As shown. The present invention can also control the lifting height of the front part of the treadmill by controlling the screw drive, that is, adjusting the slope, and the maximum lifting slope can reach 90 degrees, which can also achieve the purpose of folding. The present invention combines the two into one, and the structure is relatively simpler. It can simultaneously meet the user's requirements for labor-saving, space-saving folding and slope adjustment. It has a novel concept and promotes the progress of treadmills.

[0035] In order to reduce the friction between the rear part of the treadmill and the ground and facilitate movement, a roller 33 is provided at the rear part of the treadmill.

[0036] In one embodiment, a support base 11 in contact with the ground is provided at the bottom of the frame 1. The support base 11 is in a long strip shape, which is conducive to enhancing the grip and allowing the frame 1 to stand upright on the ground stably.

[0037] The above description is only a preferred embodiment of the present invention and is not a limitation on the design of this case. Any equivalent changes made based on the design key of this case shall fall within the protection scope of this case.
