Supporting assembly

Disclosed is a supporting assembly. The supporting assembly comprises a plurality of rigid supporting parts, elastic parts and connecting pieces. Each rigid supporting part comprises a plurality of connected secondary supporting parts. Each secondary supporting part comprises a first flat plate and two second flat plates, wherein the second flat plates are arranged in a separated mode, the side walls, facing with each other, of the two second flat plates are connected with two side walls of the first flat plate through two connecting plates respectively, and the included angle between each connecting plate and the first flat plate is an acute angle. A deformation space is defined between the first flat plate and the two connecting plates of each secondary supporting part, every two adjacent secondary supporting parts are connected through the corresponding second flat plate, and a holding space is defined between every two adjacent secondary supporting parts. The elastic parts are arranged in at least one holding space of each rigid supporting part, and the height of each elastic part is smaller than that of the corresponding rigid supporting part. Every two adjacent rigid supporting parts are connected through the corresponding connecting piece. According to the invention, the supporting assembly is simple in structure and high in shock absorption capacity, and has the advantages of being high in load bearing capacity and high in fatigue resistance.
