Abstract

This utility model discloses a treadmill lifting structure capable of achieving a high incline, including a running platform and a lifting mechanism. The top surface of the running platform is for running and is configured so that the front part can rise and fall. Rising increases the incline (higher at the front, lower at the back) of the running platform, while lowering decreases the incline. Two lifting mechanisms are provided, located on the left and right sides of the front of the running platform, respectively, to provide support for the platform. The two lifting mechanisms operate synchronously to raise or lower the front part of the running platform. This utility model improves the stability of the running platform after the front part is raised to create an incline.

Description

Technical Field

[0001] This utility model relates to the field of treadmill technology, and in particular to a treadmill lifting structure that can achieve high incline. Background Technology

[0002] In order to allow users to simulate running uphill, some current treadmills have the function of raising the front of the running platform to form a slope that is higher in the front and lower in the back. However, after the front of the current treadmill is raised, the structural stability is poor. During the running process, the deformation of the running platform is large and the shaking is obvious. This instability becomes more and more obvious as the height of the front of the running platform increases, so it is difficult to achieve a high slope. Utility Model Content

[0003] The purpose of this invention is to provide a treadmill lifting structure that can achieve a high incline. The technical problem to be solved is how to improve the stability of the treadmill after the front part of the running platform is raised to form an incline.

[0004] To achieve the above objectives, the solution of this utility model is: a treadmill lifting structure capable of achieving high inclines, including a running platform and a lifting mechanism;

[0005] The top surface of the treadmill is for people to run on, and it is configured so that the front part can rise and fall, so that by rising, the slope of the treadmill is increased from front to back, and by falling, the slope of the treadmill is decreased.

[0006] There are two lifting mechanisms, located on the left and right sides of the front of the runway, respectively, to provide support for the runway. The two lifting mechanisms operate synchronously to drive the front of the runway to rise or fall.

[0007] Furthermore, it also includes a base frame, which is used to rest on the ground and is located below the runway, with a lifting mechanism connecting the base frame and the runway;

[0008] It is also equipped with a support frame, the bottom of which is pivotally connected to the base frame so that the top of the support frame tilts backward and is pivotally connected to the running platform. When the front part of the running platform rises, the top of the support frame swings up and moves forward, and the running platform moves forward accordingly. When the front part of the running platform descends, the top of the support frame swings down and moves backward, and the running platform moves backward accordingly.

[0009] Furthermore, the connection point between the lifting mechanism and the running platform is located in front of the connection point between the support and the running platform, and the connection point between the lifting mechanism and the base frame is located behind the connection point between the support and the base frame, so that the support and the lifting mechanism form an intersection.

[0010] Furthermore, the support frame and the running platform are pivotally connected by two upper support pivot points spaced apart on the left and right, and the support frame and the base frame are pivotally connected by two lower support pivot points spaced apart on the left and right. The support portion extending between the upper and lower support pivot points on the left side is close to the lifting mechanism located on the left side, and the support portion extending between the upper and lower support pivot points on the right side is close to the lifting mechanism located on the right side.

[0011] Furthermore, the lifting mechanism is a telescopic rod capable of active extension and retraction. One end is hinged to the running platform, and the other end is hinged to the base frame, so as to lift the front of the running platform by extending.

[0012] Furthermore, the lifting mechanism is an electric push rod.

[0013] Furthermore, the bracket is formed into a bent shape with the top and bottom ends curving upwards and the middle part concave downwards.

[0014] Furthermore, the rear of the running platform is equipped with rollers, which allow the rear of the running platform to rest on the ground and roll back and forth.

[0015] Furthermore, a limiting structure is also provided, which can connect or disconnect the front end of the running platform from the base frame. After connection, the front part of the running platform is restricted from rising. The lifting point of the lifting mechanism is located behind the connection point between the running platform and the base frame, so that when the lifting mechanism lifts the running platform, the running platform rotates around the connection point between the running platform and the base frame, and the rear part of the running platform flips upward.

[0016] Furthermore, the limiting structure includes a hook; mounted on the running platform, capable of hooking or releasing a hook portion on the base frame, or mounted on the base frame, capable of hooking or releasing a hook portion on the running platform.

[0017] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0018] (1) The top surface of the running platform is for people to run on, and the front part can be raised and lowered. By raising it, the slope of the running platform is increased from front to back, and by lowering it, the slope of the running platform is reduced. There are two lifting mechanisms, which are located on the left and right sides of the front part of the running platform, respectively, to support the running platform on the left and right sides of the front part of the running platform. The two lifting mechanisms move synchronously to drive the front part of the running platform to rise or fall, thereby supporting the front part of the running platform at the left and right points, and enhancing the ability of the front part of the running platform to resist left and right twisting and swaying after it is raised.

[0019] (2) A support is also provided, with the bottom end of the support pivotally connected to the base frame so that the top end of the support tilts backward and pivotally connected to the running platform. The hinge point between the lifting mechanism and the running platform is located in front of the hinge point between the support and the running platform, and the hinge point between the lifting mechanism and the base frame is located behind the hinge point between the support and the base frame. Thus, the support supports the running platform behind the lifting mechanism. After the front part of the running platform is lifted, the bending resistance of the middle part of the running platform is improved, and the stability of the running platform is improved in conjunction with the lifting mechanism.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Embodiments of the invention will now be described in full with reference to the accompanying drawings. It should be noted that the invention may be implemented in various forms and is not limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0027] This utility model provides a treadmill lifting structure capable of achieving high inclines, combined with... Figure 1-4As shown, it includes a running platform 1 and a lifting mechanism 2. The top surface of the running platform 1 is for users to run on, specifically, a running belt 10 is installed on the running platform 1, and the user stands on the top of the running belt 10. During operation, the top side of the running belt 10 forms a backward conveyor, and the user stands on the running belt 10 to walk or run forward. This is a common design on treadmills and will not be described in further detail. The running platform 1 can form an incline that is higher in the front and lower in the back, allowing users to exercise by running uphill. Of course, it can also be adjusted to be level. The running platform 1 is configured so that the front can rise and fall, so that by rising, the front-to-back incline of the running platform 1 can be increased. The slope of the running platform 1 is reduced by lowering it, thus creating different slope angles. Two lifting mechanisms 2 are provided, located on the left and right sides of the front of the running platform 1, respectively, to provide support for the running platform 1 on both sides. The two lifting mechanisms 2 operate synchronously to raise or lower the front of the running platform 1. The two lifting mechanisms 2 support the front of the running platform 1 at two points on the left and right, enhancing the ability of the front of the running platform 1 to resist lateral twisting and swaying after being raised, improving the stability of the front of the running platform 1, and making it more suitable for forming a running platform 1 with a large slope. The lifting mechanism 2 can be any existing structure capable of providing upward lifting action and has a certain degree of rotational freedom to achieve a matching swing when lifting the front of the running platform 1, without simultaneously lifting the rear of the running platform 1. A preferred embodiment is given below. In one specific embodiment, it also includes a base frame 3, which is used to rest on the ground and is located below the running platform 1. A lifting mechanism 2 is connected between the base frame 3 and the running platform 1. Preferably, the running platform 1 is provided with a roller 9 at the rear, and the rear of the running platform 1 rests on the ground through the roller 9, which can roll back and forth.

[0028] Preferably, a support 4 is also provided, with its bottom end pivotally connected to the base frame 3, so that the top end of the support 4 tilts backward and pivotally connects to the running platform 1, specifically the front half of the running platform 1. This provides support for the running platform 1 from the rear of the lifting mechanism 2, further enhancing the stability of the support for the running platform 1 in conjunction with the lifting mechanism 2. When the front of the running platform 1 rises, the top end of the support 4 swings up and moves forward, causing the running platform 1 to move forward accordingly. When the front of the running platform 1 descends, the top end of the support 4 swings down and moves backward, causing the running platform 1 to move backward accordingly. This ensures that the center position of the running platform 1 does not shift significantly forward or backward during the slope adjustment process, preventing users standing on the running platform 1 from stepping into empty spaces due to the shift in the center position of the running platform 1, making it safer to use. In a more specific embodiment, handrails 8 extend upward from the left and right sides of the base frame 3, providing a grip for people standing on the running platform 1. The center position of the running platform does not shift significantly forward or backward, ensuring that the handrails 8 are in a position that is easy for users to grip before and after the slope adjustment of the running platform 1, making it even safer to use.

[0029] In a preferred embodiment, the support 4 is bent upwards at the top and bottom and concave in the middle. In an embodiment where a drive component such as a motor is provided on the bottom front surface of the running platform 1 to drive the running belt 10, the drive component can be moved aside. This allows the pivot point between the support 4 and the running platform 1 to be as close as possible to the front of the running platform 1 while moving the drive component aside. As a result, when the running platform 1 forms a large slope with a high front and low back, the support 4 can be supported at a higher position at the front of the running platform 1, which can more effectively improve the stability of the front of the running platform 1.

[0030] In a preferred embodiment, the support 4 and the running platform 1 have two upper support pivot points 11 spaced apart on the left and right, and the support 4 and the base frame 3 have two lower support pivot points 12 spaced apart on the left and right. The support portion extending between the upper support pivot point 11 and the lower support pivot point 12 on the left side is close to the lifting mechanism 2 located on the left side, and the support portion extending between the upper support pivot point 11 and the lower support pivot point 12 on the right side is close to the lifting mechanism 2 located on the right side. The closeness mentioned in this application refers to a smaller distance between them without interference or contact, so as to improve the resistance to left and right torsional torsion of the running platform 1, and to prevent the running platform 1 from tilting to the left and right when the two lifting mechanisms 2 fail and move asynchronously.

[0031] In a preferred embodiment, the lifting mechanism 2 is a telescopic rod. Two lifting mechanisms 2, i.e., two telescopic rods, are arranged parallel to each other and can actively extend and retract. Preferably, an electric push rod is used in this embodiment (electric push rod: after the motor is reduced by gears or worm gears, it drives a pair of lead screw nuts to move, realizing electric extension and retraction). The electric push rod has the characteristics of more stable support, self-locking, and safer and more reliable use. One end of the electric push rod is hinged to the running platform 1, and the other end is hinged to the base frame 3, so that the front of the running platform 1 can be raised by extending and the front of the running platform 1 can be lowered by shortening. More preferably, the hinge point between the telescopic rod and the running platform 1 is located in front of the pivot point between the support 4 and the running platform 1, and the hinge point between the telescopic rod and the base frame 3 is located behind the pivot point between the support 4 and the base frame 3, so that the telescopic rod and the support 4 intersect, thereby more effectively supporting the running platform 1 from multiple points. The support portion extending on the left side between the upper support pivot point 11 and the lower support pivot point 12 is close to the lifting mechanism 2 located on the left side, and the support portion extending on the right side between the upper support pivot point 11 and the lower support pivot point 12 is close to the lifting mechanism 2 located on the right side. In embodiments where the lifting mechanism 2 is positioned close to the side, the lifting mechanism 2 is a telescopic rod that intersects with the support 4. This allows the support to be positioned as close as possible to the left and right edges of the running platform 1, maximizing the platform's resistance to lateral swaying and rocking. Furthermore, the intersection allows the support 4 to distribute the weight of the running platform 1 more widely, minimizing the load on the telescopic rod. The telescopic rod also tilts forward to the maximum extent, effectively counteracting the force that causes the support 4 and telescopic rod to swing backward and fall due to the weight of the running platform 1. Even when the lifting mechanism 2 is not a telescopic rod, the same intersecting technical solution can be achieved by adjusting the connection points between the lifting mechanism 2 and the base frame and running platform to form a triangular mechanical structure and distribute the torque.

[0032] In a preferred embodiment, a limiting structure 5 is also provided. The limiting structure 5 can connect or disconnect the front end of the running platform 1 from the base frame 3. After connection, it restricts the front of the running platform 1 from rising. The lifting mechanism 2's lifting point for the running platform 1 is located behind the connection point between the running platform 1 and the base frame 3. When the lifting mechanism 2 lifts the running platform 1, the running platform 1 rotates around its connection point with the base frame 3, causing the rear of the running platform 1 to flip upwards. Specifically, the limiting structure 5 includes a hook 6; or a hook 7 installed on the running platform 1 that can hook or disconnect from the base frame 3, or a hook 7 installed on the base frame 3 that can hook or disconnect from the running platform 1. The hook connects the front end of the running platform 1 to the base frame 3, and after disconnection, the front end of the running platform 1 can resume its normal lifting motion.

[0033] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
