Embodiment Construction

[0021] The deformable cushioning safety helmet shell according to the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0022] The present invention changes the hard shell of the conventional safety helmet, that is, the cap shell, into a flexible carbon fiber material, and replaces the belt-shaped cap lining with a honeycomb structure, which improves the uneven stress state of the safety helmet under the action of external impact load, and avoids the conventional The hidden danger that the hard shell of the helmet is broken and the head is directly subjected to the impact load. The deformable energy-absorbing safety helmet with the honeycomb structure as the buffer layer not only ensures that the local force of the cap shell is not damaged when the local impact load is large, but also eliminates the hidden danger of the residual impact load directly acting on the head. The deformable buffer safety helm...

Abstract

The invention discloses a safety helmet shell capable of deforming for buffering. The safety helmet shell consists of five layers in total: a carbon fiber shell, a honeycomb sandwich, a carbon fiber liner, an outer side glue line and an inner side glue line. According to the safety helmet shell disclosed by the invention, the hard material of a conventional safety helmet shell is changed for a flexible carbon fiber material, the ribbon-shaped helmet liner is replaced with a honeycomb structure, and impact energy is absorbed by means of the deformation of the honeycomb, and therefore, the condition that a safety helmet is stressed unevenly under the action of external impact load is improved; the helmet shell cannot be broken even under the condition that the impact load is larger, and the phenomenon that the hard shell of the conventional safety helmet is broken due to impact to cause the head to be seriously injured is also eliminated. The safety helmet shell disclosed by the invention has the advantages of being simple in structural composition, convenient to manufacture and process, long in service life, and the like.

Description

technical field [0001] The invention relates to the technical field of safety helmet structure, in particular to a deformable cushioning helmet shell. Background technique [0002] In industries such as construction, coal mines, and metallurgy, helmets are the most commonly used means of protecting the heads of construction workers. Conventional safety helmets are composed of two parts: a cap shell and a belt-shaped cap liner. The cap shell is a hard shell, mostly composed of metal and hard plastic, and the tape-shaped cap liner is composed of a strip structure. The hard shell first bears the impact from the outside. As the hard shell breaks, the cap lining connected to the hard shell can further relieve the impact load, and the remaining impact load is absorbed by the head and cervical spine. [0003] The anti-shock effect of conventional safety helmets is realized by the joint action of the strip-shaped cap liner and the hard shell. The hard shell disperses the impact loa...
