The mushroom head buckle 9 undergoes a slight deformation, passes through the narrow part 82, and locks itself in the wide part 81 after rebounding. During disassembly, press the exposed pressing block 92 on the side, causing the elastic connecting block 91 to bend. The angle of the mushroom head buckle 9 changes, and the side retracts from the wide part 81 into the narrow part 82, allowing the cushioning pad 6 to be removed upwards for easy replacement or cleaning.

[0038] In summary, the helmet liner structure provided by this utility model has significant advantages. Firstly, it greatly improves the replaceability of key vulnerable components such as buckles. Through modular design, the buckles are installed on independent plastic plates, making buckle replacement exceptionally simple and quick, without touching or damaging the liner itself, greatly extending the overall service life of the liner and reducing user maintenance costs. Secondly, it innovatively adds a cushioning pad for further protection of important areas. A side-press mushroom-shaped buckle and plastic slot structure enable the removable cushioning pad. This structure is intuitive to unlock, effortless to operate, and reliable in connection, allowing users to clean or replace the cushioning pad at any time, greatly improving product hygiene and user experience. Finally, the combination of Velcro and ventilation holes ensures a secure connection between the liner and the outer shell while significantly improving breathability and comfort during wear. Overall, this utility model effectively solves the pain point of inconvenient maintenance of traditional liner structures. Its ingenious overall structural design and strong practicality make it highly valuable for market promotion.
