Description
Technical Field
[0001] The present invention relates to the technical field of robots, and in particular to a high-strength, wear-resistant corrugated power cord sheath structure for an outdoor window-cleaning robot. Background Art
[0002] With the increasing popularity of smart homes and automated cleaning devices, outdoor window-cleaning robots are attracting widespread attention for their efficient and safe cleaning capabilities. However, the outdoor environment poses significant challenges to the robots' power cord sheaths, including frequent mechanical friction, extreme temperature fluctuations, ultraviolet (UV) radiation, rain erosion, and bending fatigue. Traditional power cord sheath structures often fail to meet the wear resistance and durability requirements of long-term outdoor use, leading to sheath cracking, insulation damage, and even safety hazards.
[0003] At present, most common power cord sheaths on the market are made of a single material (such as PVC, TPU or rubber). Although they have certain flexibility and protective performance, they are easily worn due to long-term friction or bending under complex outdoor working conditions. In addition, most existing sheaths are fixed with fixed buckles or adhesives, which are easy to loosen and fall off in areas with frequent bending. Summary of the Invention
