Through the deformation of the absorber and the reciprocating action of returning to its original state, the airflow can flow automatically to achieve exhaust heat dissipation. The effect.

Description

helmet structure

The present invention belongs to a helmet technology for protecting the head, and specifically refers to a helmet structure with good energy absorption effect, which can provide the function of protecting the user's head, improve the safety of the user, and has good ventilation , further and can improve wearing comfort.

Press, the helmet is mainly used to protect the user's head. Generally, the helmet usually includes a shell and a lining with a buffering effect inside the shell, and the adjustment straps on both sides of the shell can be relatively buckled for further The helmet is fastened to the user's head in place so that the helmet can provide head protection. Therefore, helmets are widely used such as helmets for soldiers and helmets for construction workers, mine workers or locomotives and bicycle riders. For the steel helmets used by soldiers, because soldiers are in the process of training or combat, their activities and risks are much higher than those of ordinary helmets, so the quality of the entire helmet is higher.

For example, the shell system of the traditional helmet type helmet is mainly steel or high-strength composite material (multi-layer polyester glass fiber), and the inner lining is such as leather rubber ring, Styrofoam liner or Kevlar coated with resin glue Made of fiber and polyethylene foam, the inner lining can play a role of shock absorption and buffering, but the existing inner lining has limited elastic deformation due to concerns about the protection effect, so the design of the inner lining needs to be developed with different head sizes. , When there is a problem with the shape or size of the head, the traditional steel helmet often causes swelling and pain in the head after wearing it for a certain period of time, which brings great discomfort to people. Furthermore, the existing inner lining is usually in the form of a single piece, which is caused by insufficient elastic deformation. Some of the inner linings are designed with exhaust runners, but they can usually only use the heat generated by the user's head to dissipate heat. loading discomfort.
