Description

Technical Field

[0001] The present invention relates to the technical field of safety helmets, and in particular to an intelligent monitoring safety helmet for promoting standardized wearing and a use method thereof. Background Art

[0002] In modern industry and construction, hard hats, as one of the most basic personal protective equipment, are crucial to protecting the lives of workers. Hard hats are mainly used to prevent accidental injuries to the head from falling objects, collisions, etc., and are an indispensable safety protection measure at the construction site. The requirements for the wearing of hard hats by project supervisors and construction parties are becoming increasingly stringent, and ensuring that workers always wear hard hats during construction has become an important safety management task.

[0003] There are many kinds of helmets on the market, but the designs of most helmets are mainly focused on improving their physical protection performance, such as enhancing the strength of the helmet shell, adding an internal buffer layer, etc. However, the existing technical means still have certain limitations for the correct wearing of helmets. For example, patent CN221653705U proposes a standard-wearing helmet, in which an elastic member is pressed into the inside of the helmet body under the pressure of the human head to ensure that the chin strap is fastened. Patent CN103783710A provides a new type of helmet that ensures that the chin strap is worn correctly through an obstruction mechanism in the cap lining. In addition, patent CN218354812U proposes a helmet with a pressure sensor and a collection device, which uses the deadweight of the lower jaw to act on the pressure sensor to monitor the wearer's wearing condition.

[0004] Although the above-mentioned prior art has solved the problem of standard wearing of safety helmets to a certain extent, there are still some obvious shortcomings. First, the safety helmets using elastic parts (such as patent CN221653705U) are prone to shaking after wearing, which affects the comfort of wearing, and are easy to fall off when impacted, and cannot provide reliable protection. Secondly, the complex metal parts design in patent CN103783710A not only increases the weight of the safety helmet, but also may cause secondary damage to the wearer's head in the event of an accident. Finally, the pressure sensor in patent CN218354812U cannot accurately determine whether the pressure comes from the lower jaw, and is easily disturbed by the outside world, resulting in monitoring failure. These shortcomings have seriously affected the practicality and reliability of the safety helmet, and there is an urgent need for a new technology that can effectively solve these problems. Summary of the invention

[0005] In view of the above defects or improvement needs of the prior art, the object of the present invention is to provide an intelligent monitoring safety helmet and a method of use that promote standardized wearing. The safety helmet can hinder the linkage between the strap and the cheek guard.
