Description

Technical Field

[0001] The utility model relates to the technical field of helmets, in particular to a multifunctional helmet. Background Art

[0002] Helmets are used to protect the wearer's head, especially when cycling or engaging in certain sports. To ensure safety, helmets are usually worn. Currently, there are many types of traditional helmets on the market, which can be divided into several categories: full-face helmets, off-road helmets, three-quarter helmets, flip-up helmets, and half-face helmets (also called Harley helmets). Full-face helmets and off-road helmets: These two full-face helmets have a one-piece main helmet body, which can effectively protect the entire head and are the safest of all helmet types. Full-face helmets are suitable for many types of vehicles and competition venues, and have perfect full-head protection. Advantages: They provide comprehensive protection for the entire head. Full-face helmets also provide more protection from noise, sunlight, wind, rain, cold, insects, and stones. Disadvantages: They are more stuffy and lack ventilation in the summer, making them inconvenient to wear when riding. Three-quarter helmets: Compared with full-face helmets, they lack a chin structure and are more suitable for wearing when riding in spring, summer, and autumn. Advantages: They are convenient for daily use and breathable and cool for summer riding, because they look like fighter helmets. Disadvantages: They are not recommended for intense driving or high speeds. Three-quarter helmets give up the protection of the face and chin. The protection is not enough. When hit by things such as road gravel, about 30% of motorcycle accidents will hit the chin. Half helmets ignore the protection of the chin and the back of the head. It is very similar to the steel helmets used in war. This type of helmet has very poor protection and can only protect the top of the head. This type of helmet is more suitable for retro cars, scooters or low-speed driving. Advantages: light weight, cool to wear, easy to use in daily life, easy to carry; Disadvantages: poor protection, loud wind noise, poor warmth retention, not suitable for high-speed riding, flip-up helmets are A variation of the full-face helmet, it can lift up the chin and lens together to become a shape similar to a three-quarter helmet. Advantages: good convenience for daily use, average warmth retention, and less impact on use in rainy days; Disadvantages: the helmet body is large and inconvenient to carry, the helmet has an unbalanced center of gravity and is heavy, the protection is average, and the wind noise suppression is average. The above are the types of helmets traditionally available on the market according to different needs, different car models, different road sections, and different occasions. Each of these helmets has advantages and disadvantages. For this reason, we propose a multi-functional helmet. Utility Model Content
