One end of the first hinge member is connected to the driving end of the driving component, and the other end is hinged to the second frame. One end of the second hinge member is hinged to the first frame, and the other end is hinged to the second frame. The first hinge member, the second hinge member, the first frame, and the second frame together constitute a linkage mechanism.
[0008] According to the present invention, the first hinge member and the second hinge member are both arc-shaped hinge members with openings facing upwards, and their common hinge point is located at the lowest point.
[0009] According to the present invention, the driving component is a hydraulic cylinder, and the piston rod of the hydraulic cylinder is connected to the folding hinge shaft; the hydraulic cylinder is controlled by bidirectional oil pressure.
[0010] According to the present invention, the hydraulic cylinder is further provided with an overload protection valve at the tail end of the cylinder body.
[0011] According to the present invention, the folding hinge and the drive component are further disposed on one side of the running board assembly.

Detailed Implementation
[0020] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0021] like Figures 1 to 3 As shown in the figure, this application discloses a folding treadmill, including a bottom frame 100, a running board assembly 200 disposed on the top of the bottom frame 100, and a running belt 300 covering the top surface of the running board 200 and wrapped around the front and rear drive structure of the treadmill; wherein, the running board assembly 200 includes a first running board 210 and a second running board 220 disposed on one side end face thereof, the two being connected by a folding hinge shaft 400, the folding hinge shaft 400 being driven by a drive component to realize the folding or unfolding of the second running board 220 relative to the first running board 210.
[0022] Correspondingly, the bottom frame 100 includes a first frame 110 disposed at the bottom of the first running plate 210 and a second frame 120 disposed at the bottom of the second running plate 220. The first frame 110 has an inwardly facing receiving cavity, in which a driving component is disposed. Its driving end is connected to the folding hinge shaft 400, driving the folding hinge shaft 400 to fold or unfold. Both the first frame 110 and the second frame 120 are integrally formed from aluminum alloy profiles, meeting the dual requirements of lightweight and load-bearing rigidity.
[0023] The folding hinge shaft 400 includes a first hinge member 410 connected at one end to the drive end of a drive component, and the other end of the first hinge member 410 hinged to a second frame 120. The first hinge member 410 is hinged to a second hinge member 420 at a second hinge point 421 via a first hinge point 411. One end of the second hinge member 420 is hinged to a first frame 110, and the other end is hinged to the second frame 120. Both the first hinge member 410 and the second hinge member 420 are upward-opening arc-shaped hinge members, with the first hinge point 411 and the second hinge point 421 located at their lowest points. The first hinge member 410, the second hinge member 420, the first frame 110, and the second frame 120 together constitute a linkage mechanism, with the drive component serving as the power source for the folding hinge shaft 400.
[0024] In this embodiment, the driving component is preferably a hydraulic cylinder 500, whose piston rod is connected to the folding hinge shaft 400. The hydraulic cylinder 500 is controlled by bidirectional hydraulic pressure, and the extension and retraction of the piston rod are slow to avoid pinching the operator during the folding process. An overload protection valve is provided at the tail of the cylinder body of the hydraulic cylinder 500, which automatically releases pressure when the folding resistance exceeds a preset value to prevent the two running plates from pinching each other. The driving component can be located on one side or both sides of the running plate assembly. The driving component can also be a component capable of applying driving force, such as an electric push rod.
[0025] In this embodiment, the running board assembly 200 uses a high-density fiberboard with a composite structure of an EVA buffer layer and a wear-resistant surface, which improves the shock absorption and wear resistance of the running board assembly 200. The mating end faces of the first running board 210 and the second running board 220 are chamfered at 10°, and a transition strip of flexible material is provided on the end faces to reduce the hard collision between the first running board 210 and the second running board 220 and improve the overall service life.
[0026] The working principle of this invention is as follows:
[0027] Deployed state: The piston rod of the cylinder changes from the original contracted state to the extended state, applying a force away from the cylinder to the first hinge 410, causing the second hinge 420 to rotate synchronously around the hinge point, so that the hinge end of the second hinge 420 and the second frame 120 moves downward, thereby causing the second running board 220 to move downward to the same plane as the first running board 210, completing the deployment of the treadmill.
[0028] Folded state: The piston rod of the cylinder changes from the original contracted state to the extended state, applying a force close to the cylinder to the first hinge 410, which drives the second hinge 420 to rotate synchronously around the hinge point, causing the hinge end of the second hinge 420 and the second frame 120 to rise, thereby causing the second running board 220 to flip towards the first running board 210 until the two upper surfaces are in contact, completing the folding of the treadmill.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
