[0072] In some embodiments, the second bracket 200 includes a first rod 210 and a second rod 220 spaced apart along a second direction Y, and the first bracket 100 includes a third rod 110 and a fourth rod 120 spaced apart along the second direction Y. The seat 10 includes a first connecting rod 910, a second connecting rod 920, a third connecting rod 930, a fourth connecting rod 940, a fifth connecting rod 950, a sixth connecting rod 960, a seventh connecting rod 970, and an eighth connecting rod 980.

[0073] In some embodiments, the first connecting rod 910 has two ends connected to the first rod 210 and the second rod 220, respectively. The second connecting rod 920 has two ends connected to the first rod 210 and the second rod 220, respectively. The first connecting rod 910 and the second connecting rod 920 are arranged crosswise and connected. This allows the first connecting rod 910 and the second connecting rod 920 to rotate relative to each other during the folding or unfolding of the seat 10, so that the end of the first connecting rod 910 connected to the first rod 210 and the end of the second connecting rod 920 connected to the second rod 220 move closer to or further away from each other, thereby allowing the first rod 210 and the second rod 220 to move closer to or further away from each other, thereby achieving a more stable folding or unfolding process.

[0074] In some embodiments, the ends of the third connecting rod 930 are connected to the first rod 210 and the third rod 110, respectively. The ends of the fourth connecting rod 940 are connected to the first rod 210 and the third rod 110, respectively. The third connecting rod 930 and the fourth connecting rod 940 are arranged crosswise and connected. This allows the third connecting rod 930 and the fourth connecting rod 940 to rotate relative to each other during the folding or unfolding of the seat 10, so that the end of the third connecting rod 930 connected to the first rod 210 and the end of the fourth connecting rod 940 connected to the third rod 110 move closer to or further away from each other, thereby moving the first rod 210 and the third rod 110 closer to or further away from each other, thereby achieving a more stable folding or unfolding of the seat 10.

[0075] In some embodiments, the ends of the fifth connecting rod 950 are respectively connected to the second rod 220 and the fourth rod 120, and the ends of the sixth connecting rod 960 are respectively connected to the second rod 220 and the fourth rod 120. The fifth connecting rod 950 and the sixth connecting rod 960 are arranged crosswise and connected. This allows the fifth connecting rod 950 and the sixth connecting rod 960 to rotate relative to each other during the folding or unfolding of the seat 10, so that the end of the fifth connecting rod 950 connected to the second rod 220 and the end of the sixth connecting rod 960 connected to the fourth rod 120 move closer to or farther from each other, thereby moving the second rod 220 and the fourth rod 120 closer to or farther from each other, thereby achieving folding or unfolding of the seat 10, and the folding or unfolding process is more stable.

[0076] In some embodiments, the ends of the seventh connecting rod 970 are respectively connected to the third rod 110 and the fourth rod 120, and the ends of the eighth connecting rod 980 are respectively connected to the third rod 110 and the fourth rod 120. The seventh connecting rod 970 and the eighth connecting rod 980 are arranged crosswise and connected. This allows the seventh connecting rod 970 and the eighth connecting rod 980 to rotate relative to each other during the folding or unfolding of the seat 10, so that the end of the seventh connecting rod 970 connected to the third rod 110 and the end of the eighth connecting rod 980 connected to the fourth rod 120 move closer to or farther from each other, thereby moving the third rod 110 and the fourth rod 120 closer to or farther from each other, thereby achieving folding or unfolding of the seat 10, and the folding or unfolding process is more stable.

[0077] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
