Recommendation of cost-effective helmets

Racing helmet:

Mainly refers to the helmet used in automobile competitions. For example, used in F1 competitions, the F1 driver's helmet is composed of three materials: carbon, Kevlar fiber, and polyethylene. Helmets used in F1 races must of course pass the FIA's "impact and fire performance test." What is different from other racing helmets is that when the car is running on the track at a speed of 330 kilometers per hour, the air turbulence flowing through the helmet will not only cause a great burden on the driver's neck (the helmet drifts upward), but also reduce the engine speed. Air intake effect. Therefore, the helmets used by F1 drivers have also been designed by aerodynamic engineers (you can see many spoilers on the surface), and have even become part of the development plan for new racing cars.

The helmet is equipped with a radio supply device (convenient for drivers to communicate with team managers and technicians), as well as a drinking water tube for drivers to replenish water during the race. Fans who are unfamiliar with the game may not understand the physical load placed on F1 drivers. This isn't just an easy job done by turning the steering wheel. The driver's heart beats more than 200 times per minute throughout the race. After the race, the driver will lose 3 to 4 kilograms of weight (lost water). Therefore, the first thing a driver should do after a race is to replenish water. Imagine that on a hot afternoon, you have to wear an airtight fireproof racing suit under a huge amount of exercise. An annual salary of several million pounds a year is not that easy to earn! In order to reduce the temperature inside the helmet during competition, the ventilation ducts in the helmet have also been carefully designed to optimize their function of removing heat from the helmet.

The surface of the driver's helmet goggles is covered with multiple layers of plastic film (called Visor), each piece is about 0.3 mm thick. Dust, oil and dirt often get on the helmet during competition, and riders will tear off a layer of Visor after a period of time to ensure clear vision. Since 2002, the FIA ??has stipulated that helmets must be integrated with the neck support device HANS. HANS has been an essential protective tool for drivers in North American racing for many years.

Bicycle helmets can be divided into: downhill helmets, ordinary riding helmets

Equestrian helmets:

Equestrian helmets can be divided into: equestrian helmets, knight helmets, horse racing helmets

Other sports helmets can be divided into: skateboard helmets, mountain climbing helmets, roller skating helmets (downhill helmets, stunt helmets), ice hockey helmets, baseball helmets, speed skating helmets, skating helmets, ski helmets, skating helmets, Hockey helmets, football helmets, roller skating helmets, hip-hop helmets, extreme sports helmets

Hockey helmets:

All players must wear hockey helmets, referees and line referees can also wear helmets . In age group competitions approved by the IIHF for those aged 20 or under, athletes must wear full-face masks whose structure should be able to block the passage of the puck or hockey stick blade.

Roller skating helmet:

1. EPS (polypropylene) helmet. The inside of the helmet is polypropylene and the outside is made of plastic shell.

2. ABS (engineering plastic) hard plastic shell and EPS (polypropylene) lining, mostly used in extreme roller skating and FSK and other projects. Mainly used to prevent collision with hard objects and protect the head.

3.ABS (engineering plastic) hard plastic shell and hard sponge lining, mostly used in ice hockey and in-line skating. It is mainly used to prevent collision with hard objects and protect the head from the impact of ice balls. Many helmets can be equipped with a plexiglass or wire-welded face shield.

4. Helmets with chin protection are basically made of glass fiber or carbon fiber shell and EPS lining. Some varieties are made of pure EPS, and the part of the chin protection can be removed. This type of helmet is used for downhill skating.

5. Aerodynamic helmets are basically made of glass fiber or carbon fiber shells with smooth surfaces, and some are lined with EPS. The shape is very unique. The front part is a large goggle, which covers half of the face. The rear part of the helmet is very long. When gliding, it just rectifies the part where the neck and the back meet, reducing air resistance. Hence the name aerodynamic helmet.

Football helmet:

Americans love football. It is exciting for the audience to see athletes wearing full protective clothing running on the field, falling down, and scoring touchdowns. However, while this strenuous exercise brings excitement and stimulation to the audience, it also causes serious injuries to the athletes, especially to the head. Therefore, rugby must wear a special helmet.

Ski helmet:

The ski helmet is made of hard plastic molding or fiberglass outer shell. The helmet has an impact-resistant EPS inner shell and a special, matching, comfortable and elastic inner lining for thermal insulation. Layer, the entire helmet is streamlined, relatively lightweight, does not affect the field of vision, and skiers feel safe wearing it. Helmets are generally divided into full-face helmets and half-face helmets. Half-face helmets are suitable for wearing when doing tricks, making it easier to hear various sounds from the outside world and have heat dissipation functions; full-face helmets are suitable for speed competitions. Ski helmets are often used in alpine skiing downhill and super-G, ski jumping, aerials and other events.
