The invention relates to an air cushion easy to fold and unfold. The air cushion comprises an air bag and a supporting structure. An air port is formed in the air bag so as to inflate and deflate the air bag; the supporting structure is arranged in the air bag in the first direction and can stretch out and draw back in the first direction. A first receding opening and a second receding opening are formed in the two opposite sides of the supporting structure in the first direction correspondingly, so that when the air bag exhausts air outwards, the two opposite side walls of the air bag shrink and are embedded into the first receding opening and the second receding opening, the supporting structure is driven to be folded in the first direction, the first receding opening and the second receding opening are closed, and the air bag shrinks in the first direction; the side wall of the air bag can be folded regularly according to the distribution of the first avoiding opening and the second avoiding opening of the supporting structure, the contraction ratio in the first direction after air exhaust is large, when the air bag is inflated, the supporting structure stretches in the first direction, the first avoiding opening and the second avoiding opening are opened, the air cushion is convenient to store and unfold, and use is more convenient.

    本发明涉及一种易收放的气垫,包括气囊和支撑结构;气囊上设有气口,以对气囊内充放气体;支撑结构在气囊内沿第一方向设置,并能在第一方向伸缩;支撑结构的两相对侧沿第一方向分别排布有第一避让口、第二避让口,以在气囊向外抽气时,气囊两相对的侧壁收缩嵌入到第一避让口、第二避让口内,且带动支撑结构在第一方向折叠,第一避让口、第二避让口闭合,使得气囊在第一方向收缩,气囊的侧壁会按支撑结构的第一避让口、第二避让口的分布有规律地折叠,抽气后在第一方向的收缩比大,并在向气囊内充气时,支撑结构在第一方向伸展,第一避让口、第二避让口打开,便于气垫的收纳和展开,让使用更便利。
