Description

Technical Field

[0001] The utility model belongs to the technical field of individual protective equipment, and specifically relates to an intelligent safety protection helmet for special working scenes, such as for the self-protection of workers in emergency, fire fighting and dangerous working scenes. Background Art

[0002] As head protection equipment, helmets are widely used in various fields such as emergency, firefighting, construction, mining, transportation, etc. They can play a good role in protecting the important head of the human body during production or sports activities to avoid accidents. They are indispensable personal protective equipment for people's production and life. However, traditional ordinary helmets only play the role of protecting the user's head. They are only a passive defense equipment and do not incorporate intelligent technology.

[0003] With the rapid development of science and technology, some special-purpose smart helmets are now available on the market. For example, traditional helmets are equipped with headphones and microphones, and sockets for installing additional equipment such as cameras and flashlights are reserved, and connected to user terminal devices, so that communication, video, lighting, etc. can be directly performed when wearing the helmet. This has to some extent solved the problem that the emerging takeaway and express delivery industries cannot communicate with customers in time when riding with helmets. However, the above-mentioned helmets cannot achieve true intelligence, and the user experience is not good. This is because in the use scenario, the personnel protection and operation capabilities depend not only on the protection capabilities of the protective equipment, but also on their situational awareness capabilities and information intelligence levels at the scene, especially the police and firefighters who are always in danger. Therefore, how to enable users to understand the surrounding and external situations in a timely manner, and how to enable the rear support personnel to obtain personnel information and needs at the fastest speed and to the greatest extent have become important issues that need to be solved urgently. In addition, most of the intelligent devices on existing smart helmets are fixed structures, which are inconvenient for later maintenance and replacement, and have fewer supporting functions, resulting in a poor user experience.

[0004] In view of this, this utility model is proposed. Utility Model Content
