DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model. Example

[0018] like Figure 1-4The inner frame of a pull-out sofa shown in the figure includes a bed body 1 and a frame body 7, and is characterized in that: the frame body 7 includes two parallel supporting longitudinal rods, and also includes a plurality of parallel supporting cross rods, the supporting cross rods are arranged between the opposite surfaces of the supporting longitudinal rods, and a cushion 3 is provided at the top of the frame body 7. The bed body 1 includes a bed frame with a U-shaped cross-section, a ball screw assembly 16 is provided at the top of the bed frame, a slide plate 14 is provided at the top of the ball screw assembly 16, the slide plate 14 is screwed to the bottom end of the supporting longitudinal rod, a first connecting rod 15 is provided at one end of the supporting longitudinal rod, a vertically arranged transverse dividing plate 11 and a longitudinal dividing plate 10 are provided at the bottom end of the frame body 7, and also includes a bottom plate, which is arranged on the bottom plate of the longitudinal dividing plate 10, and also includes a storage box 5, which is arranged in the area surrounded by the transverse dividing plate 11, the longitudinal dividing plate 10 and the bottom plate, and the bottom plate is slidably matched with the inner side surface of the bed frame.

[0019] A support plate 4 is provided at the bottom end of the frame 7 away from the first connecting rod 15 , and a universal wheel 2 is provided at the bottom end of the support plate 4 .

[0020] A handle 6 is provided on the outer side of the storage box 5 .

[0021] The bed body 1 further comprises an armrest 8 arranged on the top of the bed frame.

[0022] The ball screw assembly 16 includes a ball screw and a drive motor, and the output end of the drive motor is connected to the ball screw through a coupling.

[0023] A flap 12 is disposed at the top end of the first connecting rod 15 .

[0024] A second connecting rod 17 is provided at the bottom end of the flap 12 away from the first connecting rod 15, and a support plate 13 is provided at the top of the second connecting rod 17. The second connecting rod 17 includes a fixed connecting rod 1701, a first support rod 1702 is hinged at one end of the first fixed connecting rod 1701, a second support rod 1704 is hinged at one end of the first support rod 1702, a second fixed connecting rod 1705 is hinged at one end of the second support rod 1704, and a spring 1703 is also included, and both ends of the spring 1703 are respectively connected to the first support rod 1702 and the second support rod 1704.

[0025] In this embodiment, the ball screw is driven by the driving motor of the ball screw assembly 16 to push the frame 7 to move horizontally along the longitudinal direction. Since the ball screw assembly 16 is arranged at the top of the bed frame of the bed body 1, and the cross-section of the bed frame is U-shaped, the area between the frame 7 and the bottom end of the bed frame is left empty, and then the longitudinal partition plate 10, the transverse partition plate 11 and the bottom plate are installed at the bottom end of the frame 7 to divide the cavity space between the bottom end of the frame 7 and the bottom end of the bed frame into several areas, and then the storage box 5 is installed in each area, thereby achieving the purpose of improving space utilization.

[0026] In another embodiment, the bed body 1 also includes a headboard 9. The headboard 9 of the bed body 1 includes a lower enclosing plate and an upper headboard. The upper headboard is hinged to the lower enclosing plate, and the upper headboard is screwed to the second fixed link 1705. When the frame body 7 is unfolded, the frame 7 pulls the first fixed link 1701 to move forward, and then pulls the first support rod 1702 and the second support rod 1704. Since the first support rod 1702 and the second support rod 1704 are hinged and connected by a spring 1703, the angle between the first support rod 1702 and the second support rod 1704 is close to 180 degrees, and then the second fixed link 1705 is driven to fold the upper headboard downward, thereby increasing the length of the bed body to meet the needs of taller people.

[0027] The above are only preferred embodiments of the present invention, which are only used to illustrate the scheme and effect of the present invention and cannot be considered to limit the scope of implementation of the present invention. It should be pointed out that for ordinary technicians in this technical field, several changes and improvements can be made without departing from the concept of the present invention, which should still fall within the scope of the patent coverage of the present invention.
