Many motorcycle drivers do not wear helmets as required in daily life, but helmets play a vital role in the safety of drivers. Today, I would like to introduce the purchase of motorcycle helmets, the safety protection effect of each part of the structure on driving, and how to maintain the helmets.

Helmets have many functions, such as windproof, rain proof, insect proof and cold proof, but the more important function is to ensure personal safety. Therefore, the safety of helmets must be taken into account when choosing helmets. The following points should be paid attention to when purchasing helmets:

1. Look at the safety signs on the helmet. Domestic helmets are subject to production license and national safety standards. Imported motorcycle safety helmets shall bear the following marks: TIS for Japanese products, SNE for American products, and ECE for European products.

2. Look at the strength of the helmet. When purchasing a helmet, press the helmet hard to see if it is easy to deform. If it is easy to deform or soften, it will not have a good protective effect.

3. Try it on. When trying it on, the key is to be comfortable, and try to see if its shape and size are appropriate.

The motorcycle helmet is generally composed of six parts. The following are the safety protection functions of each part structure for the driver:

1. Hat shell: the outer hard shell of the helmet. In case of accidental collision, the cap shell is the first line of defense to protect the head to disperse the impact force.

2. Cap body: the foam inner layer inside the helmet. It is the second line of defense to protect the head. It is mainly used to absorb the impact force in accidents and reduce accident injuries.

3. Buckle and headband (safety harness): used to fix the helmet position. The hat band is fixed below the ears on both sides, and the buckle is fixed at the throat. Note: After the snap ring is fastened, the snap ring and throat shall be reserved with 1 to 2 finger spaces, and it shall not be too tight or too loose.

4. Air hole: Air hole is to help the head heat dissipation and ventilation, which can ensure the dryness of hair during long-distance riding. The more air holes, the cooler the rider will feel, but the lower the relative safety factor. Generally, helmets with appropriate air holes are preferred.

5. Knob: There is a knob on the back of the motorcycle helmet to adjust the tightness. The driver can adjust the size of the helmet according to the size of his head.

6. Cushion: Cushion can absorb sweat and micro vibration from human body during cycling.
