[0027] In the embodiment, the middle panel 1 is provided with a first inner wing panel 3 and a second inner wing panel 4 at two ends, and the first inner wing panel 3 and the second inner wing panel 4 are connected through a first hinge structure 5. The hinge connection mode allows the first inner wing panel 3 and the second inner wing panel 4 to rotate relative to each other, realizing folding and unfolding actions. The second inner wing panel 4 is provided with an outer wing panel 6 away from one end of the first inner wing panel 3, and the second inner wing panel 4 and the outer wing panel 6 are connected through a second hinge structure 7, also realizing the folding of the outer wing panel 6 relative to the second inner wing panel 4. The middle panel 1 is provided with an inner wing driving mechanism 8, which drives the first inner wing panel 3 and the second inner wing panel 4 to fold and unfold. The second inner wing panel 4 is provided with a sliding block type outer wing driving mechanism 9 for driving the outer wing panel 6 to fold and unfold. When the first inner wing panel 3, the second inner wing panel 4 and the outer wing panel 6 are completely unfolded, the bottoms of the three are in abutment with the support frame body 2. The bottom of the outer wing panel 6 is provided with a rolling support 10 which rolls with the support frame body 2. The rolling support 10 not only assists in supporting the outer wing panel 6, but also reduces friction during unfolding and folding through rolling, making the operation more smooth. The creativity lies in the ingenious design of the connection mode of each component and the driving mechanism, which realizes the foldable and unfoldable structure of the whole, and forms a stable support structure after unfolding.

[0028] As shown in Figures 1-3 The sliding block type outer wing driving mechanism 9 includes an outer wing folding cylinder 11 arranged on the second inner wing panel 4. The outer wing panel 6 is internally provided with a sliding connecting piece 12 which slides with the outer wing panel 6. The power shaft of the outer wing folding cylinder 11 is connected with the sliding connecting piece 12.

[0029] Specifically, when the outer wing folding cylinder 11 works, the power shaft pushes the sliding connecting piece 12 to slide in the outer wing panel 6, thereby driving the outer wing panel 6 to rotate around the second hinge structure 7, realizing the folding and unfolding actions of the outer wing panel 6.
