[0030] Working principle: When in use, first adjust the thigh support plate 111 and the calf support plate 114 to the lowest position, then the user lies on the reclining board 116 and puts the legs on the thigh support plate 111 and the calf support plate 114, and according to the user's body length ratio, use the slide groove 102 to adjust the two support plates 103 to the optimal position, and then start the drive motor 104 to drive the bidirectional threaded rod 107 to rotate, adjust the distance between the user's legs to achieve the most comfortable position, and at the same time, further adjust the leg position by controlling the extension and retraction degree of the electric push rod A109 and the electric push rod B112 respectively. Under the action of the bearing B110 and the bearing C113, the thigh support plate 111 and the calf support plate 114 can be automatically adjusted according to the user's leg direction to avoid discomfort to the user. In the backrest adjustment mechanism 2, the extension and retraction of the hydraulic rod 205 is utilized to control the lowering and lifting of the backrest board 201. The height of the backrest board 201 is adjusted to meet the needs of different users. When the user needs to get down, the support device only needs to be moved in the opposite direction of the backrest board 201 through the slide slot 102, and the electric push rod A109 and the electric push rod B112 are controlled to be lowered to the lowest position. Then, the hydraulic rod 205 is used to lift the backrest board 201 to assist the user to get down. In this way, the support device can be user-centered and the distance between the leg support board and the backrest can be freely adjusted according to the height ratio of different users. In this way, the user can accelerate physical recovery, provide support and stability, reduce pain and discomfort, and improve the psychological state. At the same time, the comfort of the device is ensured, and the convenience and practicality of the device are improved.
