The structure and function of motorcycle helmets The importance of motorcycle helmets

1. The structure and function of motorcycle helmets Motorcycle helmets look very simple, like a beautiful shell with some foam stuck inside, but it is not. Motorcycle helmets are high-tech products. It is a complex, multi-layered technical system consisting of five parts: outer shell, buffer layer, inner lining, face shield and fixing system. 1. Shell The shell is the first line of defense of a motorcycle helmet, absorbing and dispersing impact energy. The shell is usually subject to small bumps, such as falling off the seat when parked, without affecting your protection, and small bumps or scratches will not affect its performance. The material of the shell helmet includes ABS resin material, PC+ABS alloy material, glass fiber reinforced plastic, carbon fiber, etc. Among them, the material of the shell carbon fiber has the highest technical content. 2. Buffer layer The function of the buffer layer is to slow down the movement through deformation and damping. When a motorcycle is involved in an accident, an emergency stop can be fatal to the head when it falls and hits the ground. The role of the buffer layer is to slow down the movement and avoid sudden stops. The buffer layer is generally EPS (expanded polystyrene) material, and it is best to sandwich several different densities together. 3. Lining The lining fits snugly against the head. Its main job is to wrap the helmet around the head, preventing it from wobbling or spinning. It also reduces noise inside the helmet, absorbs shock, sweat and skin oils, acting as a barrier between the head and the cushioning layer. A good motorcycle helmet usually has a removable comfort pad. 4. Facing Qin The function of the mask is to allow the owner to see the road clearly, while preventing things from bouncing off the road and hurting the face. Good masks are made of polycarbonate and tested for penetration resistance. 5. Retention system A retention system is a method that allows the motorcycle helmet to be fastened to the head to prevent the helmet from tilting forward and slipping off the head. Many drivers don’t like to have the fasteners fastened so that the motorcycle helmet will turn around in the event of an accident, which is no different than not wearing a helmet. The Importance of Motorcycle Helmets Motorcycle helmets are very important and must-have equipment for motorcyclists. If nothing else, according to my country’s “Road Traffic Management Regulations” and related laws, motorcycles are motor vehicles, and they are not allowed to go on the road without a motorcycle helmet. If you wear a motorcycle helmet, the traffic police will not check you for fines. Of course, we don’t wear hard hats to prevent fines. The functions of motorcycle helmets are: 1. Buffer protection Motorcycle helmets provide buffers for the head in the event of an accident. The smooth hemisphere of the helmet dissipates and absorbs the impact force, while the deformation or cracking of the helmet and liner also acts as a buffer, absorbing some of the energy. 2. Windproof and noise reduction Motorcycles travel fast, but do not have the narrow space of cars. The wind is still unpleasant, and the noise caused by the wind will also affect the driver’s ability to judge. Therefore, the wind and noise protection of the helmet is still very important. 3. Meeting reminder Motorcycle helmets are usually in bright and eye-catching colors, so that they can attract the attention of the other driver and look good when meeting or overtaking. It looks tall and professional.
