Technical Field

[0001] This utility model relates to the field of safety helmet technology, and in particular to an adjustable adhesive strap for a smart safety helmet. Background Technology

[0002] The helmet strap is an important component of a smart safety helmet. It is typically made of materials such as fabric or plastic and is usually located inside the helmet, wrapping around it. Its function is to prevent the safety helmet from accidentally falling off during work, allowing it to better perform its protective function. Without the strap, the safety helmet can easily shift in the event of a collision or accidental fall, failing to properly protect critical parts of the head. The strap ensures that the safety helmet remains in the correct position upon impact, evenly distributing the impact force.

[0003] Currently, common smart helmet straps use adhesive Velcro straps, which are convenient, quick, highly adjustable, secure, and durable. However, after prolonged use, Velcro straps wear down, deform, and pill after repeated friction, affecting their effectiveness and causing the straps to become loose. Therefore, there is an urgent need to design an adjustable adhesive strap for smart helmets to solve these problems. Utility Model Content
