[0011] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0012] A foot lowering mechanism includes a hip frame 1, a leg frame 2, and a foot frame 3, which are rotatably connected by hinges. A support frame 4 is fixedly connected to the bottom of the hip frame 1. A leg motor assembly 5 and a foot motor assembly 6 are respectively provided on the front side of the support frame 4. The leg motor assembly 5 drives the leg frame 2 to rotate relative to the hip frame 1, and the foot motor assembly 6 drives the foot frame 3 to rotate relative to the leg frame 2.

[0013] This invention, by setting up a leg motor assembly 5 and a foot motor assembly 6, can drive the leg frame 2 and foot frame 3 to rotate, thereby realizing the free switching between the flat, raised and lowered states of the leg frame 2 and foot frame 3, thus meeting the usage needs of elderly people with limited lower limb mobility.

[0014] Furthermore, in another embodiment, the leg motor assembly 5 includes a leg motor 51 rotatably connected to the support frame 4, and a first rotating bracket 52 rotatably connected to the telescopic end of the leg motor 51, the rotating bracket 52 being fixedly connected to the leg frame 2.

[0015] By setting up the leg motor assembly 5, the leg frame 2 is driven to rotate under the mutual cooperation of the leg motor 51 and the first rotating bracket 52, thereby adapting to multi-angle adjustment of the legs.

[0016] Furthermore, in another embodiment, the foot motor assembly 6 includes a foot motor 61 rotatably connected to the support frame 4, a second rotating bracket 62 rotatably connected to the telescopic end of the foot motor 61, a rotating rod 63 fixedly connected to the second rotating bracket 62, a roller bracket 64 fixedly connected to both ends of the rotating rod 63, a roller 65 mounted on the roller bracket 64, and a roller guide rail 66 that cooperates with the roller 65 to roll, wherein the roller guide rail 66 is fixedly connected to the foot frame 3.

[0017] By setting up the foot motor assembly 6, the foot frame 3 is driven to rotate under the mutual cooperation of the foot motor 61, the second rotating bracket 62, the rotating rod 63, the roller bracket 64, the roller 65 and the roller guide rail 66, thereby adapting to multi-angle foot adjustment.

[0018] Furthermore, in another embodiment, the two ends of the rotating rod 63 are rotatably connected to the two sides of the support frame 4, respectively.

[0019] The working principle of one embodiment of this utility model is as follows: When laid flat, the leg frame 2 and hip frame 1 are in an unfolded state, and the foot frame 3 is kept horizontal with the leg frame 2. At this time, the leg motor assembly is in the initial position, and each frame maintains a stable horizontal posture through hinges.

[0020] When in the lowered position, the leg motor assembly 5 is activated, and the leg motor 51 retracts to drive the first rotating bracket 52, causing the leg frame 2 to rotate upward around the hinge with the hip frame 1 and lift up; at the same time, the foot motor assembly 6 works in coordination, and the foot motor 61 drives the second rotating bracket 62 and the rotating rod 63 to roll on the guide rail 66 through the roller 65, causing the foot frame 3 to rotate upward relative to the leg frame 2, thus lifting the foot as a whole.

[0021] When raised, the leg motor 51 extends to push the first rotating bracket 52, causing the leg frame 2 to rotate downwards around the hinge; the foot motor 61 extends simultaneously, and through the cooperation of the rotating rod 63, roller 65, and guide rail 66, drives the foot frame 3 to rotate downwards relative to the leg frame 2, ultimately bringing the foot frame 3 into contact with the ground, completing the lowering action. Throughout the process, the rotational connection between the rotating rod 63 and the support frame 4 ensures the stability of the movement of each component.

[0022] Based on the description and drawings of this utility model, those skilled in the art can easily manufacture or use a foot lowering mechanism of this utility model, and can produce the positive effects described in this utility model.
