Description

Technical Field

[0001] This utility model relates to the field of safety helmets, and in particular to a safety helmet liner assembly with a positioning structure. Background Technology

[0002] Safety helmets are primarily used to protect the wearer's head from potential injuries, preventing head injuries caused by falling objects or collisions. The inner lining is a crucial component of a safety helmet, providing comfort, cushioning, and protection to reduce head injuries from external impacts.

[0003] Existing safety helmets typically use adhesives to bond the inner liner to the outer shell. Adhesive bonding provides strong hold, preventing the liner from detaching or shifting during strenuous activity and securing the liner assembly. However, the adhesive strength decreases with prolonged use or exposure to high temperatures. This can lead to an unstable connection between the liner and the outer shell, especially under severe impacts or collisions, where the adhesive may fail to provide sufficient support, thus compromising safety performance.
