Description

Technical Field

[0001] The utility model relates to the technical field of helmets, in particular to a displacement buffer structure for helmets. Background Art

[0002] The working principle of cycling helmets is to protect people by absorbing the impact of collisions. Every cycling helmet has a buffer layer, which can directly resist the impact of external forces on the head when an accident occurs. The buffer layer and the helmet shell can absorb part of the impact force. However, although existing helmets can buffer the impact force, part of the impact force is still received by the head.
