Bionic bicycle helmet with tortoiseshell structures

thingiverse

A bionic bicycle helmet based on a tortoiseshell structure, designed to absorb more energy when subjected to an impact, so as to provide better protection for the head. The helmet consists of two layers, the outer layer is like the scutes of a tortoise shell, made of hard materials. The inner layer imitates the bone glue between the scute pieces and is made of soft material. When subjected to an impact, the nail pieces on the outer layer will accumulate against each other, and the flexible material of the inner layer will be compressed and absorb energy. Please note: This model is only a conceptual prototype, and its protective effect has not been proved. It is only used to show concepts and should not be worn in riding!
