Description

Technical Field

[0001] This disclosure relates to the field of sports equipment technology, and more specifically, to a treadmill. Background Technology

[0002] With the increasing demand for home exercise, treadmills have become a common piece of exercise equipment for families to run and work out. Treadmills typically have two functions: incline adjustment and running platform retraction. However, in current technology, these two functions are achieved through two separate structures, which makes the treadmill's structure very complex, increases costs, and is also detrimental to production. Summary of the Invention

[0003] The purpose of this disclosure is to provide a treadmill that reduces the structural complexity of the treadmill.

[0004] To achieve the above objectives, this disclosure provides a treadmill, comprising: a support including a base and a first and second upright mounted on the base; a running platform having a first end and a second end opposite to each other; and a lifting and folding mechanism including a drive member, a first movable member, a linkage structure, and a second movable member. The drive member is tractively connected to the first movable member, the first movable member is tractably mounted on the first upright along a first direction, the second movable member is tractably mounted on the second upright along the first direction, and the first movable member is tractably connected to the first end via the linkage structure, the second movable member being rotatably connected to the first end. The lifting and folding mechanism is configured such that the treadmill can switch between a flat state, an incline state, and a folded state. In the flat state, the running platform is parallel to the base. In the incline state, an angle is formed between the running platform and the base, and the first end is higher than the second end. In the folded state, the running platform is rotated around the first end until the projection of the running platform in the first direction is located within the area defined by the base.

[0005] Optionally, the linkage structure includes a first linkage and a second linkage, wherein the first linkage is hinged to the first movable member and the second linkage at both ends, and the second linkage is fixedly connected to the first end.

[0006] Optionally, the base is provided with an abutment structure. In the stored state, the second movable member abuts against the abutment structure to restrict the movement of the second movable member in the first direction, so that the running platform frame rotates around the rotational connection point with the second movable member.

[0007] Optionally, the abutment structure is constructed as a pad, and the abutment structure is arranged close to the second upright and opposite to the second movable member in the first direction.

[0008] Optionally, a sliding connection structure is provided between the second upright and the second movable member. The sliding connection structure includes a slide rail and a slider. The slide rail extends along the first direction and is fixed to the second upright. The slider slides in cooperation with the slide rail. The second movable member is fixedly installed on the slider.

[0009] Optionally, a lifting guide structure is provided between the first upright and the first movable component. The lifting guide structure includes a guide rail and a guide block. The guide rail extends along the first direction and is fixed to the first upright. The guide block slides with the guide rail. The first movable component is fixedly installed on the guide block.

[0010] Optionally, the treadmill further includes a limiting member disposed on the first upright and used to constrain the movement of the first movable member in the first direction.

[0011] Optionally, the driving component is configured as a motor, and the lifting and storage mechanism includes a motion conversion structure. The motion conversion structure is connected between the driving component and the first movable component and is used to convert the rotational motion of the driving component into the linear motion of the first movable component in the first direction.

[0012] Optionally, the motion conversion structure includes a lead screw and a movable block that are threaded together, the lead screw extending along the first direction and being drivenly connected to the output shaft of the drive member, and the movable block being fixedly connected to the first movable member.

[0013] Optionally, the second end is provided with a roller.

[0014] Through the above technical solution, the treadmill of this disclosure is equipped with a lifting and storage mechanism, which can realize two different functions as needed: incline adjustment and storage. When it is necessary to flatten the running platform, the drive component drives the first movable component to move along the first direction on the first upright, causing the first movable component to descend. The first movable component, through a linkage structure, drives the second movable component to descend on the second upright. The second movable component drives the running platform to descend until the running platform is parallel to the base, at which point the treadmill is in a flat state. When it is necessary to adjust the incline of the treadmill, the drive component drives the first movable component to rise. During the rise of the first movable component, it drives the linkage structure, which in turn pulls the second movable component to rise. During the rise of the second movable component, it pulls the first end of the running platform to rise, thus forming an incline. By controlling the degree to which the first end of the running platform is raised, the incline of the treadmill can be adjusted. When the treadmill needs to be stored, it is adjusted to the storage position. At this time, the drive mechanism drives the first movable component to descend. Once the first movable component reaches a level position, the drive mechanism continues to drive it downwards, and through a linkage structure, it drives the second movable component to descend. The second movable component then stops descending after reaching a certain point. The continuously descending first movable component then uses the linkage structure to lift the running platform frame, causing it to flip upwards until the running platform frame is completely stored. Using this disclosed treadmill, both incline adjustment and storage functions can be achieved with a single structure, reducing the complexity of the treadmill's structure.

Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, unless otherwise stated, "inner" and "outer" refer to the inner and outer contours of the corresponding parts themselves, and "far" and "near" refer to the outer and near dimensions relative to a comparative reference object. Furthermore, terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not have sequential or material significance. In the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0031] According to a specific embodiment of this disclosure, refer to Figures 1 to 10As shown, a treadmill includes: a running platform 2 having a first end 21 and a second end 22 opposite to each other; a support 1 including a base 11 and a first upright 12 and a second upright 13 disposed on the base 11; and a lifting and storage mechanism including a drive member 31, a first movable member 32, a connecting rod structure 33, and a second movable member 34. The drive member 31 is throttlely connected to the first movable member 32. The first movable member 32 is throttlely mounted on the first upright 12 in a first direction. The second movable member 34 is throttlely mounted on the second upright 13 in the first direction. The first movable member 32 is throttlely connected to the first end 21 through the connecting rod structure 33, and the second movable member 34 is rotatably connected to the first end 21.

[0032] The lifting and storage mechanism is configured to allow the treadmill to switch between flat ground, incline, and storage states. In the flat ground state, the running platform 2 and the base 11 are parallel to each other. In the incline state, the running platform 2 and the base 11 are at an angle, and the first end 21 is higher than the second end 22. In the storage state, the running platform 2 is rotated around the first end 21 until the projection of the running platform 2 in the first direction is located within the area defined by the base 11.

[0033] Through the above technical solution, the treadmill of this disclosure is equipped with a lifting and storage mechanism, which can realize two different functions as needed: incline adjustment and storage. When it is necessary to flatten the running platform 2, the drive component 31 drives the first movable component 32 to move along the first direction on the first upright 12, causing the first movable component 32 to descend. The first movable component 32 drives the second movable component 34 to descend on the second upright 13 through the connecting rod structure 33. The second movable component 34 drives the running platform 2 to descend until the running platform 2 is parallel to the base 11, at which point the treadmill is in a flat state. When it is necessary to adjust the incline of the treadmill, the drive component 31 drives the first movable component 32 to rise. During the rise of the first movable component 32, the connecting rod structure 33 pulls the second movable component 34 to rise. During the rise of the second movable component 34, the first end 21 of the running platform 2 is pulled to rise, thus forming an incline. By controlling the degree of lifting of the first end 21 of the running platform 2, the incline of the treadmill can be adjusted. When the treadmill needs to be stored, it is adjusted to the storage state. At this time, the drive unit 31 drives the first movable part 32 to descend. Once the first movable part 32 reaches the height of the ground, the drive unit 31 continues to drive it downwards, and through the linkage structure 33, drives the second movable part 34 to descend. After the second movable part 34 descends to a certain point, it stops descending. At this point, the continuously descending first movable part 32, through the linkage structure 33, lifts the running platform 2, causing it to flip upwards until the running platform 2 is completely stored. Using this disclosed treadmill, both incline adjustment and storage functions can be achieved with a single structure, reducing the complexity of the treadmill structure.

[0034] Among them, reference Figures 1 to 3 As shown, the first end 21 and the second end 22 are the two ends along the length of the running platform 2, with the first end 21 being closer to the first upright 12 than the second end 22. The drive component 4 can be mounted on the support 1 or at other locations. The second movable component 34 is hinged to the first end 21 of the running platform 2, and a bearing is installed at the hinge position to achieve a rotational connection between the two. The base 11 is made of a metal frame. The first upright 12 and the second upright 13 both extend along the first direction and are fixed to the base 11. There are two first uprights 12, distributed along a second direction perpendicular to the first direction. There are also two second uprights 13, located on both sides of the running platform 2 in the second direction. Two sets of lifting and storage mechanisms are also provided. The first movable component 32 of each of the two sets of lifting and storage mechanisms is slidably connected to one of the first uprights 12, and the second movable component 34 of each of the two sets of lifting and storage mechanisms is slidably connected to one of the second uprights 13.

[0035] Appendix Figure 4 This diagram illustrates the treadmill when it is on level ground. At this position, the running platform 2 is parallel to the base 11, meaning the running belt on the running platform 2 is horizontal. (Attached) Figure 6 and attached Figure 7 This is a schematic diagram of the treadmill in incline mode. At this point, the first end 21 is raised, creating an incline on the running platform 2. (Attached) Figure 8 This is a state diagram at a certain moment during the storage process, attached. Figure 9 and attached Figure 10 This is a diagram illustrating the storage state, specifically the state after storage is complete. (See attached image.) Figure 9 and attached Figure 10 In the embodiment shown, the storage state is that the running platform 2 is stored in a vertical state. In other embodiments, the running platform 2 can be stored in an inclined state. As long as the projection of the running platform 2 in the first direction is within the range of the base 11, the storage effect can be achieved.

[0036] In the specific embodiments provided in this disclosure, reference is made to Figure 2 and Figure 3 As shown, the linkage structure 33 includes a first linkage 331 and a second linkage 332. The two ends of the first linkage 331 are respectively hinged to the first movable member 32 and the second linkage 332, and the second linkage 332 is fixedly connected to the first end 21.

[0037] With the above technical solution, in the slope state, the first movable part 32 slides upward along the first direction and pulls the first end 21 of the running platform 2 up through the first link 331 and the second link 332; in the flat state, the first movable part 32 slides downward along the first direction and lowers the first end 21 of the running platform 2 through the first link 331 and the second link 332, so that the running platform 2 is in a horizontal state; in the storage state, the first movable part 32 continues to slide downward from the flat state position, and the second movable part 34 stops sliding downward after it comes into contact with the base 11 or the ground. Since the second link 332 is fixedly connected to the running platform 2, and both are hinged to the second movable part 34, during the continuous downward movement of the first movable part 32, the first link 331 and the second link 332 lift the running platform 2 so that the running platform 2 can be flipped upward until it is stored.

[0038] Among them, reference Figure 2 and Figure 3 As shown, each linkage structure 33 includes a first linkage 331 and two second linkages 332. The two second linkages 332 are located on both sides of the first linkage 331 in the second direction. One end of the second linkage 332 in the length direction is hinged to the first linkage 331, and the other end in the length direction is fixedly connected to the first end 21 of the treadmill frame 2. After the second linkage 332 is fixed to the treadmill frame 2, it is hinged to the second moving part 34 through a bearing.

[0039] In the specific embodiments provided in this disclosure, reference is made to Figure 5 As shown, the base 11 is provided with an abutment structure 111. In the retracted state, the second movable member 34 abuts against the abutment structure 111 to restrict the movement of the second movable member 34 in the first direction, causing the running platform 2 to rotate around the rotational connection point with the second movable member 34. With this design, when the second movable member 34 descends to a certain extent, it will abut against the abutment structure 111. At this point, the second movable member 34 will no longer descend, and the descending first movable member 32 can then be used to tilt the running platform 2 and rotate via the connecting rod structure 33. In other embodiments, the abutment structure 111 may be omitted, and the second movable member 34 will stop descending after it touches the ground or the base 11.

[0040] In other embodiments, the abutment structure 111 can be a metal block, as detailed in the specific embodiments provided in this disclosure. Figure 5 As shown, the abutment structure 111 is constructed as a pad, and is arranged close to the second upright 13 and opposite to the second movable member 34 in the first direction. With this design, when the second movable member 34 abuts against the pad, it no longer slides downwards. At this point, continuously pressing down one end of the second connecting rod 332 will lift the running platform 2. The abutment structure 111 can be a rubber pad, and is fixedly installed on the base 11 with screws.

[0041] In order to achieve smooth sliding of the second movable component 34 on the second upright 13, in the specific embodiments provided in this disclosure, refer to... Figure 2 As shown, a sliding connection structure is provided between the second upright 13 and the second movable member 34. The sliding connection structure includes a slide rail 131 and a slider 132. The slide rail 131 extends along a first direction and is fixed to the second upright 13. The slider 132 is slidably engaged with the slide rail 131, and the second movable member 34 is fixedly mounted on the slider 132. With the above design, when the second movable member 34 slides, it drives the slider 132 to slide. The slider 132 engages with the slide rail 131, enabling the second movable member 34 to slide smoothly on the second upright 13. There are two second uprights 13, and the second movable members 34 in both sets of lifting and storage mechanisms are slidably connected to the corresponding second upright 13 through the sliding connection structure.

[0042] In order to achieve smooth sliding of the first movable component 32 on the first upright 12, in the specific embodiments provided in this disclosure, refer to... Figure 2 As shown, a lifting guide structure is provided between the first upright 12 and the first movable member 32. The lifting guide structure includes a guide rail 121 and a guide block 122. The guide rail 121 extends along a first direction and is fixed to the first upright 12. The guide block 122 is slidably engaged with the guide rail 121. The first movable member 32 is fixedly mounted on the guide block 122. With the above design, when the first movable member 32 slides, it drives the guide block 122 to slide. The guide block 122 engages with the guide rail 121, enabling the first movable member 32 to slide smoothly on the first upright 12. There are two first uprights 12, and the first movable members 32 in both sets of lifting and storage mechanisms are slidably connected to the corresponding first upright 12 through the lifting guide structure.

[0043] In the specific embodiments provided in this disclosure, reference is made to Figure 2 As shown, the treadmill also includes a limiting member 4, which is mounted on the first upright 12 and used to constrain the movement stroke of the first movable member 32 in the first direction. Through this design, when the first movable member 32 moves downward to a certain extent, it will collide with the limiting member 4, preventing the first movable member 32 from moving excessively downward. The limiting member 4 can be a metal block and is located at the bottom of the first guide rail 121.

[0044] In the specific embodiments provided in this disclosure, reference is made to Figure 2As shown, the driving member 31 is constructed as a motor, and the lifting and storing mechanism includes a motion conversion structure 35. The motion conversion structure 35 is drively connected between the driving member 31 and the first movable member 32, and is used to convert the rotational motion of the driving member 31 into the linear motion of the first movable member 32 in a first direction. In other embodiments, the driving member 31 can be a hydraulic cylinder or a pneumatic cylinder, which lifts or lowers the first movable member 32.

[0045] In the specific embodiments provided in this disclosure, reference is made to Figure 2 As shown, the motion conversion structure 35 may include a lead screw 351 and a movable block 352 that are threadedly connected to each other. The lead screw 351 extends along a first direction and is driven by the output shaft of the drive member 31. The movable block 352 is fixedly connected to the first movable member 32. With this design, the drive member 31 drives the lead screw 351 to rotate, the rotation of the lead screw 351 drives the movable block 352 to move, and the movable block 352 drives the first movable member 32 to move, thereby achieving the lifting and lowering of the first movable member 32. The drive member 31 can drive the rotation of the lead screw 351 through a belt drive structure or a gear drive structure.

[0046] To facilitate the movement of the treadmill 2, in the specific embodiments provided in this disclosure, refer to Figure 1 As shown, a roller 23 is provided at the second end 22. When the treadmill 2 moves due to slope adjustment, the roller 23 facilitates the movement of the treadmill 2. Two rollers 23 can be provided, and the two rollers 23 are distributed along the second direction at the bottom of the second end 22 of the treadmill 2.

[0047] The specific implementation principle of this embodiment is as follows: When the incline of the treadmill needs to be adjusted, the first movable part 32 is driven to slide by the drive member 31. The lifting and sliding of the first movable part 32 drives the linkage structure 33 to move, and the linkage structure 33 pulls the first end 21 of the running platform 2 to rise and fall, so that the treadmill enters the incline state, realizing the adjustment of the incline. Similarly, the first movable part 32 is driven to move down by the drive member 31. After the first movable part 32 lowers the linkage structure 33, the first end 21 of the running platform 2 is also lowered, so that the treadmill is adjusted to a flat state. When the drive member 31 continues to drive the first movable part 32 to move down, since the second movable part 34 stops moving down after sliding down to a certain extent, the first end 21 of the running platform 2 is pressed down by the linkage structure 33, causing the second end 22 of the running platform 2 to tilt up, and the entire running platform 2 flips upward until it is stored. At this time, the treadmill is in the stored state. The treadmill disclosed herein can achieve both incline adjustment and running platform storage functions with a single structure, reducing the complexity of the treadmill structure.

[0048] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0049] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0050] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
