Abstract

The invention discloses a helmet capable of weakening the superimposed effect of explosive shock waves in the helmet, and relates to the field of mechanics. The helmet comprises a helmet shell system, a cushion block system and a fixing bolt system. The helmet shell system comprises a front helmet shell, a middle helmet shell and a rear helmet shell. The cushion block system is fixed in the helmet shell system and used for fixing the helmet to the head of a protected person. The middle helmet shell is fixedly connected with the front helmet shell and the rear helmet shell through the fixing bolt system. A first gap with preset spacing is reserved between the top of the front helmet shell and the top of the rear helmet shell. The middle helmet shell is located at a preset distance below the first gap, so that second gaps are formed between the middle helmet shell and the front helmet shell and between the middle helmet shell and the rear helmet shell in the upper and lower spatial positions; and the width of the middle helmet shell is larger than the preset spacing. According to the helmet provided by the embodiment, the superimposed effect of the explosive shock waves in the helmet is effectively weakened, the safety of the head of the protected person is guaranteed, and the helmet has extremely high practical value.

Description

technical field [0001] The invention relates to the field of mechanics, in particular to a helmet that weakens the superposition effect of explosion shock waves in the helmet. Background technique [0002] Explosives in the air will generate strong shock waves when they explode, which will cause damage to surrounding objects and pose a major threat to the safety of personnel. Therefore, the protection of explosion shock waves is particularly important. A typical form of equipment in helmet-type personnel protection, which provides effective protection for the personnel's head. However, the current helmets are mainly designed to improve ballistic performance, and their performance in protecting against blast shock waves is relatively weak. [0003] For the personnel wearing the helmet, the explosion shock wave can pass through the gap between the helmet shell of the helmet and the personnel's head, and enter the inside of the helmet shell of the helmet. The explosion shock ...
