Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment, and in particular to an intelligent fire-fighting helmet with a front-mounted hidden flipping mechanism. Background Art

[0002] The fire-fighting helmet consists of a helmet shell, a face mask, a cape, a buffer layer, etc. It has a semi-helmet design with novel styles and has properties such as protection against sharp object impacts, corrosion resistance, heat radiation resistance, reflectivity, insulation, and lightness. An air respirator and a wireless communication system can be worn inside the helmet, and there are obvious reflective signs.

[0003] With the development of science and technology, the protection and adaptability of old-fashioned helmets can no longer meet the requirements of modern fire-fighting work. Therefore, many countries have developed new composite material helmets. The fire-fighting helmets originally used in our country followed the form of military steel helmets in terms of cap shape, and the material was phenolic fiberglass. Subsequently, an inlaid protective face mask and a combined waterproof cape were added, thus improving the fire and heat insulation performance. Later, the helmet liner was improved, the safety distance at the top of the helmet was increased, and the impact absorption performance was improved.

[0004] The current fire-fighting helmets have a simple structure and very single functionality. With the development of technology, more and more intelligent technologies have been applied to fire-fighting helmets to become intelligent fire-fighting helmets. However, the device positions of intelligent fire-fighting helmets on the market are fixed and exposed, unable to be hidden, resulting in limited protection performance. At the same time, the working environment of firefighters is mostly at a relatively high temperature, and the wearing comfort of fire-fighting helmets is relatively poor. Working for a long time consumes a lot of physical energy of firefighters. At the same time, the structure of the fire-fighting helmet is fixed, unable to be adjusted according to needs, and the battery life is not long. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to solve the problems existing in the above background art, to provide an improved intelligent fire-fighting helmet with a front-mounted hidden flipping mechanism, and to solve the problems that the device positions of intelligent fire-fighting helmets on the market are fixed and exposed, unable to be hidden, resulting in limited protection performance, at the same time, the working environment of firefighters is mostly at a relatively high temperature, the wearing comfort of fire-fighting helmets is relatively poor, working for a long time consumes a lot of physical energy of firefighters, at the same time, the structure of the fire-fighting helmet is fixed, unable to be adjusted according to needs, and the battery life is not long.
