DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1, as Figures 1-3 shown, a force-measuring platform for motion monitoring includes anti-reflective tempered glass 1. The first type of spirit level 2 and the second type of spirit level 3 are arranged on the force-bearing platform 4. The anti-reflective tempered glass 1 is arranged at the upper end of the force-bearing platform 4. The first groove 11 and the second groove 12 are arranged on the force-bearing platform 4. The control box 5 is arranged at the lower end of the force-bearing platform 4. Multi-dimensional force sensors 6 are arranged at the four corner positions at the lower end of the force-bearing platform 4. The first adjustable floor foot 7 is arranged at the lower end of the multi-dimensional force sensor 6. The lower end of the first adjustable floor foot 7 is connected to the leveling lock nut 8. The leveling lock nut 8 is cooperatively connected with the mounting screw 9. The mounting screw 9 is arranged in the second adjustable floor foot 10. The lower end of the leveling lock nut 8 is connected to the second adjustable floor foot 10.

[0020] The optimized force platform structure design has the center of the force platform designed as anti-reflective ultra-clear tempered glass while meeting the load-bearing requirements of the force platform, opening a window for observing the subject's foot condition from the ground, which provides convenience for installing the observation camera. It solves the dilemma that the existing force platform cannot observe the subject's foot condition from the ground; a leveling program is built into the controller, and a strip level for leveling is embedded in the force platform. When the force platform is used portably, it can help the installer provide parameters for adjusting the level of the force platform and the force on its four corners, and then adjust the level of the force platform and the force on its four corners through the floor feet device that can be rotated to adjust the height.
