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

Description

Helmet structure

This creation belongs to a helmet technology that protects the head. Specifically, it refers to a helmet structure with good energy absorption, which can protect the user's head to improve the safety of the user and has good ventilation. , Further and can improve the comfort of wearing.

According to the helmet, the helmet is mainly used to protect the head of the user. Generally, the helmet usually includes a shell and a cushioning inner lining provided in the shell, and the adjustment straps that can be buckled on both sides of the shell for further Fasten the helmet to the proper position of the user's head so that the helmet can provide head protection. Therefore, helmets are widely used in helmets such as military helmets and helmets for construction workers, mine workers, or motorcycle and bicycle riders. Taking the steel helmet used by the military as an example, the amount of activity and the risk to bear is much higher than that of the general helmet, so the quality of the entire helmet is higher.

For example, the shell system of the traditional helmet-type helmet is mainly made of steel or high-strength composite materials (multi-layer polyester glass fiber), and the inner lining is made of leather rubber ring, styrofoam liner or Kevlar coated with resin glue. Made of fiber and polyethylene foam, the inner lining can play a shock-absorbing and buffering effect, but the existing inner lining is under the protection effect The amount of elastic deformation is limited, so the lining design needs to be developed with different head sizes. When there is a problem with the head shape or size, the traditional helmet will often cause head pain after being worn for a certain period of time. Occurs, and brings great discomfort to people. Moreover, the existing linings are usually made of a one-piece shape, which is caused by insufficient elastic deformation. Even though some of the linings are designed with exhaust runners, they can usually only be carried out by using the heat generated by the user’s head. Heat dissipation, for soldiers with a large amount of activity, has a poor heat dissipation effect, which in turn causes discomfort for users to wear.

Furthermore, some of the existing inner lining materials are water-absorbent, which can easily absorb rainwater or user's sweat, and produce peculiar smell when damp, and it is not easy to replace, which affects the user's personal hygiene and causes a great impact on the user's wear and load. Troubles.

In other words, due to the imperfect inner lining design of the existing helmets, there are problems such as insufficient energy absorption and poor ventilation respectively, which makes the helmet unable to effectively improve its protection and also causes discomfort to wear. Therefore, there is indeed an improvement to the existing helmet. It is necessary to solve the aforementioned problems, and it is a topic that the industry is eager to think about, and it is also a topic that this creation wants to explore.

In view of this, the creator has made an in-depth discussion on the problems faced by the aforementioned existing helmets, and upholds many years of rich design development and practical production experience in the related industry, and has researched and improved the existing shortcomings. After continuous hard work and trial production, he finally succeeded. A helmet structure was developed to overcome the inconvenience and trouble caused by insufficient elasticity of the existing inner lining.

Therefore, the main purpose of this creation is to provide a helmet structure, In this way, better energy absorption function can be provided, and the overall supporting effect can be improved to further improve the safety of users.

In addition, the second main purpose of this creation is to provide a helmet structure that can generate automatic airflow during the user's activities to provide better exhaust and heat dissipation, and has the effect of cooling and ventilation, thereby improving the wear and load. Comfortable, and can effectively prevent sultry heatstroke.

Furthermore, another main purpose of this creation is to provide a helmet structure that can improve its elastic strain, so that it can have a greater deformation effect under the support specification, so as to meet different head sizes and avoid wearing a certain size. After time, the head swelling and pain caused by compression will further improve the comfort of wearing.

What's more, another main purpose of this creation is to provide a helmet structure. The inner lining does not have water absorption, so it will not produce peculiar smell due to absorption of rain or sweat, and it can be easily disassembled and replaced by users for self-cleaning. To maintain personal hygiene.

Based on this, this creation is mainly through the following technical means to achieve the aforementioned goals and effects: It includes;

A housing having an inner edge surface, and at least one connecting portion is provided on the inner edge surface;
