The safety helmet is a hat which can protect the head of a person from being hurt by falling objects and other specific factors. The safety helmet consists of a helmet shell, a helmet liner, a chin strap, accessories and the like. The protection mechanism is as follows: buffering and damping effects: a gap of 25-50 mm is formed between the helmet shell and the helmet liner, and when an object hits the safety helmet, the helmet shell is not directly affected to the top of the helmet due to stress deformation; dispersing stress action: the hat shell is oval or hemispherical, the surface is smooth, and when an object falls on the hat shell, the object cannot stay and immediately slides; and the cap shell is transmitted to the surroundings by the force received by the striking point. The force reduced by the buffering of the cap liner can reach more than 2/3, and the rest force is transferred to the skull of a person through the moving area of the cap liner, so that the acting point is changed into an acting surface, the stress concentration of the impact force on a certain point on the cap shell is avoided, and the stress of the unit area is reduced; biomechanics: the safety helmet must absorb 4900N, which is regulated by the standard because biological tests show that the maximum limit of human cervical vertebra is the maximum limit when the human cervical vertebra is stressed, the cervical vertebra is injured when the limit is exceeded, a light person causes paralysis, and a heavy person threatens life.
