Description

Technical Field

[0001] This application relates to the field of treadmill technology, and in particular to a lifting structure for a treadmill. Background Technology

[0002] A treadmill is a device that allows an object to run or walk on the upper part of a moving circular belt (running belt), thereby enabling indoor running and walking, for example, for training and rehabilitation.

[0003] Among existing treadmills, there are those capable of simulating uphill sections. These treadmills are often equipped with a lifting structure that can raise the running platform. Such lifting structures are divided into manual lifting structures and electric lifting structures. Electric lifting structures have advantages such as precise control and labor saving. Existing electric lifting structures include a rear-powered treadmill lifting mechanism as proposed in publication number CN201692564U. The two ends of its lifting device are respectively connected to one end of the bottom support and rotatably connected to the center area of ​​the running platform. One end of the running platform is hinged to one end of the bottom support, and a support rod is set to ensure its connection strength. However, this connection method requires the running platform to have a long running platform length in the incline state. Therefore, in the flat state, there is a long area of ​​the running platform that exceeds the handrails and control panel. This part of the area cannot be effectively utilized in the flat state, and it is not possible to extend the incline to a larger angle. Therefore, how to solve the above problems is the purpose of this application.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a lifting structure for a treadmill to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a lifting structure for a treadmill, including: a mounting bracket and a running platform rotatably mounted on the mounting bracket. One end of the running platform is provided with an extended outer shell, which is triangular in shape and rotatably connected to the mounting bracket. A support leg is movably disposed below the extended outer shell. A lifting device is provided between the running platform and the mounting bracket. One end of the lifting device is rotatably connected to the bottom of the running platform, and the other end is rotatably connected to the mounting bracket. The lifting device includes a driver and an extension arm. The driver extends the extension arm to lift the running platform and put it into an incline state and a flat state. The support leg can provide support for the running platform in the lifted state.

[0007] In some embodiments, the length of the running platform is greater than the length of the mounting bracket.

[0008] In some embodiments, the extended housing includes a ramp that approaches parallel to the ground when the treadmill's lift angle is at its maximum.

[0009] In some embodiments, the driver drives the extension arm to move via a motor screw drive, an electric push rod, a hydraulic push rod, or the like.

[0010] In some embodiments, the hinge point connecting the running platform to the lifting device is located in the middle of the running platform and near the extended housing.

[0011] In some embodiments, the mounting bracket includes a first bracket and a second bracket. The first bracket is disposed on one side of the second bracket and is rotatably connected to the running platform. The second bracket is used to mount handrails and an operation panel. The side of the second bracket connected to the first bracket is rotatably connected to the lifting device.

[0012] In some implementations, the lifting device can drive the treadmill to lift at a negative angle, with the negative angle range being 0-1.5°.

[0013] The beneficial effects of this application are as follows: This application is provided with a triangular extended shell, so that part of the running platform extends beyond the hinge point in the flat state. Therefore, the length of the running platform extending beyond the handrail and control panel in the flat state can be relatively reduced, effectively improving the utilization rate of the running platform in the flat state. Furthermore, through the support of the legs in the slope state, the legs can share more of the pressure of the lifting device. Therefore, one end of the lifting device can be connected between the first support and the second support, increasing the maximum angle range in the slope state, and even enabling negative angle lifting.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them.

[0021] In the embodiments of this application, please refer to Figure 1-4 As shown, this application provides a lifting structure for a treadmill, mainly comprising: a mounting bracket 1 and a running platform 2 rotatably mounted on the mounting bracket 1. One end of the running platform 2 is provided with an extension shell 21, which is triangular in shape and rotatably connected to the mounting bracket 1. A support leg 211 is movably disposed below the extension shell 21. A lifting device 3 is disposed between the running platform 2 and the mounting bracket 1. One end of the lifting device 3 is rotatably connected to the bottom of the running platform 2, and the other end is rotatably connected to the mounting bracket 1. The lifting device 3 includes a driver 31 and an extension arm 32. The driver 31 extends the extension arm 32 to lift the running platform 2 and put it into an incline state and a flat state. The support leg 211 can provide support for the running platform 2 in the lifted state.

[0022] Specifically, the triangular extended outer shell 21 allows the running platform 2 to extend beyond the hinge point in the flattened state. This reduces the length of the running platform 2 that exceeds the handrail and control panel in the flattened state without changing the length of the running platform 2 and the mounting bracket 1. This effectively improves the utilization rate of the running platform 2 in the flattened state. Because the running platform 2 extends beyond the hinge point, it forms a lever relationship with the mounting bracket 1. The support legs 211 can assist in the support in the slope state and share the pressure borne by the lifting device 3.

[0023] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0024] Specifically, in order to enable the running platform 2 to have a longer path to adapt to the slope, the length of the running platform 2 is greater than the length of the mounting bracket 1.

[0025] Preferably, in order to assist the support of the outrigger 211, the extended outer shell 21 includes an inclined surface 212, which is nearly parallel to the ground when the lifting angle of the running platform 2 reaches its maximum.

[0026] The driver 31 drives the extension arm 32 to move through a motor screw drive, electric push rod, hydraulic push rod, etc. Specifically, in this embodiment, a motor screw drive is used. The driver 31 has a built-in motor and gear transmission group. The extension arm 32 is a screw. The motor starts and drives the gear transmission group to drive the screw to extend or retract stably and at a uniform speed, and has strong support strength.

[0027] Specifically, in order to increase the maximum lifting range of the running platform 2, the hinge point connecting the running platform 2 to the lifting device 3 is located in the middle of the running platform 2 and close to the extended outer shell 21.

[0028] Specifically, the mounting bracket 1 includes a first bracket 11 and a second bracket 12. The first bracket 11 is disposed on one side of the second bracket 12. The first bracket 11 is rotatably connected to the running platform 2. The second bracket 12 is used to install handrails and an operation panel. The side of the second bracket 12 connected to the first bracket 11 is rotatably connected to the lifting device 3.

[0029] Preferably, in order to meet the different needs of users, the lifting device 3 can drive the running platform 2 to lift at a negative angle, and the negative angle lifting range of the running platform 2 is 0-1.5°.
