Specify whether the Bluetooth helmet needs to be replaced

The main purpose of the hard shell on the helmet is to protect the polystyrene foam under the helmet in daily use. Although the hard shell does help to spread the force to larger areas during impact, the polystyrene foam really absorbs the impact. According to this statement, the very small cracks near the vent will not seriously affect the protection of the Bluetooth helmet.

1. If you find large cracks on the Bluetooth helmet, such as those along the edge of the helmet shell or connecting the two vents, it's time to replace your helmet.

2. Are the fixtures secure

In addition to determining the wearing comfort, the helmet fixing device also has the function of fixing the helmet without shaking, making it more fit the back of the user's head and increasing safety and stability. Therefore, if a helmet fixing device is loose, broken or worn, it means that the helmet has lost its most basic protection function and needs to be replaced in time.

3, the bubble part

The foam part inside the Bluetooth helmet is the most important part of protecting the head when it is thrown. It is mainly used to absorb the impact force in the accident and reduce the injury. The bicycle helmet has a hard plastic shell and a polystyrene foam inner layer. These bubbles can absorb impact force and bear external forces through their own fragmentation so as to reduce the strength of the head and play a protective role.

The inner layer of the helmet should not be soft or fragile. Long term exposure or exposure to chemicals can cause bubbles to break down, which means that there is no way to protect you when an accident happens. If so, you need to replace your helmet immediately.

If the foam feels strong, check if there is any crack. If there is a description, it should be replaced.

4. The stress positions of the hat belt buckle will cause the gum to become brittle and fracture due to long-term use or exposure to the sun, which needs to be checked regularly.

5. In addition to the fixing mechanism of the back of the head, the loosening of the fixing belt on both sides of the temple is also a symbol that needs to be replaced.

The helmet pad will gradually become thinner and damaged after long-term use, which needs to be replaced in time, otherwise it will affect the wearing comfort. Since many brand helmets are not equipped with an additional set of pads for replacement, the helmet pad becomes dilapidated, which also means that your helmet is not far from retirement.
