The invention discloses an isosceles trapezoid section straight quadrangular prism mechanism capable of being folded in a bunchy mode, and belongs to the field of space folding and unfolding mechanisms. The mechanism is provided with two isosceles trapezoid units in mirror symmetry and a rectangular unit with the two sides sharing the same-side bevel edges of the two isosceles trapezoids. Meanwhile, the isosceles trapezoid units and the rectangular units are connected through connecting rods, and the connecting rods are connected through connecting pieces to form rotating pairs; and meanwhile, four connecting rods on the top surface and the bottom surface of the whole mechanism are foldable rods. The degree of freedom of the mechanism is 1, the shape of the unfolded mechanism is a straight quadrangular prism with an isosceles trapezoid section, the angle of the isosceles trapezoid can be changed within a certain range, and the shape of the folded mechanism is bundle-shaped. The isosceles trapezoid section straight quadrangular prism mechanism is simple in motion control, convenient to produce and machine, capable of achieving bunchy folding, large in working space after being unfolded and rich in appearance, and has important significance and wide application prospects in the fields of buildings, aviation, spaceflight and the like.
本发明公开一种可束状折叠的等腰梯形截面直四棱柱机构,属于空间折展机构领域。机构具有呈镜面对称的两个等腰梯形单元,以及两侧共用两个等腰梯形同侧斜边的矩形单元;同时等腰梯形单元与矩形单元采用连杆连接而成,各连杆间通过连接件连接形成转动副;同时整个机构顶面与底面四根连杆采用可折叠杆。机构自由度为1,展开后外形为等腰梯形截面直四棱柱,等腰梯形角度可在一定范围内变化,折叠后外形为束状。本发明运动控制简单,生产加工方便,可实现束状折叠,展开后工作空间大且外形丰富,在建筑、航空、航天等领域中有重要意义和广泛应用前景。
