Safety helmet with rotary impact buffering function

Abstract

A safety helmet with a rotary impact buffering function comprises a shell and an elastic liner arranged in the shell, wherein a gap is formed between the shell and the elastic liner, and a rotary impact buffering device enabling the shell to rotate relative to the elastic liner is arranged between the shell and the elastic liner. When the safety helmet is impacted by external force, the shell has the tendency to rotate relative to the elastic liner under the effect of component force applied to the shell in the tangential direction; however, through tangential deformation of the rotary impact buffering device, the shell can rotate relative to the elastic liner by a certain angle on the premise of keeping the elastic liner unmoved, and thus the impact to users from external force is greatly reduced.
