[0020] In the present embodiment, the bedside gear seat structure includes a gear box 41 fixedly mounted on the right side of the bed frame 1, a threaded column 42 is rotatably mounted between the inner top wall and the inner bottom wall of the gear box 41, and the outer surface of the threaded column 42 is threadedly connected to a support plate 43 having one end passing through the gear box 41 and extending to the inside of the bed frame 1, so that rotating the threaded column 42 can control the support plate 43 to move up and down, and a limit assembly 44 for limiting the support plate 43 to move only up and down is provided inside the bed frame 1, and the limit assembly 44 includes a rectangular groove and a limit column, which is fixedly mounted between the inner top wall and the inner bottom wall of the rectangular groove, and the rectangular groove is opened inside the bed frame 1, and the limit column One end of the gear box 41 passes through the support plate 43, and the inner wall of the support plate 43 is slidably connected to the outer surface of the limit column, so that the support plate 43 can only move up and down on the outer surface of the guide column. An asynchronous motor 45 is fixedly installed on the inner bottom wall of the gear box 41, and a gear transmission assembly 46 for driving the threaded column 42 to rotate is provided on the front side of the asynchronous motor 45. The gear transmission assembly 46 includes two bevel gears, and the outer surfaces of the two bevel gears are meshed with each other. The two bevel gears are fixedly installed on the outer surface of the output shaft of the asynchronous motor 45 and the outer surface of the threaded column 42, respectively, so that the asynchronous motor 45 can drive the threaded column 42 to rotate by meshing the two bevel gears.
