The invention discloses a bionic sucker-bristle composite structure for a slippery rough wall surface. The structure comprises a suction cup body, the center of the bottom of the sucker body is recessed to form a cavity, a circle of flange is formed at the part of the sucker body at the periphery of the cavity; a plurality of submillimeter-level bulges are arranged at the bottom of the flange of the sucker body; a plurality of micron-sized bristles are arranged at the bottom of each submillimeter-sized bulge; a plurality of nano-scale fluff is arranged at the bottom of each micron-scale bristle; a shape memory alloy driving structure is embedded in the suction cup body, the shape memory alloy driving structure is powered on, so that the shape memory alloy driving structure deforms due to temperature changes, the suction cup body is driven to deform, the size of the cavity of the suction cup body is changed, and then the adsorption force of the suction cup body is adjusted. The bionic sucker-bristle composite structure has the advantage that stable adsorption on the slippery rough wall surface is realized. Autonomous adsorption and desorption can be realized.
本发明公开了一种用于湿滑粗糙壁面的仿生吸盘‑刚毛复合结构,包括吸盘本体,吸盘本体底部中心内凹形成空腔,吸盘本体在位于空腔外围的部分形成一圈凸缘,吸盘本体的凸缘底部设有多个亚毫米级凸起,每个亚毫米级凸起底部设有多个微米级刚毛,每个微米级刚毛底部设有多个纳米级绒毛,吸盘本体内嵌设有形状记忆合金驱动结构,通过给形状记忆合金驱动结构通电,使得形状记忆合金驱动结构由于温度变化而产生形变,从带动吸盘本体产生形变,使得吸盘本体的凹腔体积产生变化,进而调节吸盘本体的吸附力。本发明的优点:实现了在湿滑粗糙壁面的稳定吸附。且可实现自主吸附与脱附。
