[0031] See also Figures 1 to 5As shown, the helmet of the embodiment of the present application includes a helmet body 1 and a head circumference adjuster 2 fixed to the helmet body 1. In some embodiments, the head circumference adjuster 2 is detachably assembled on the helmet body 1 to facilitate replacement of the head circumference adjuster 2.

[0032] The head circumference adjuster 2 includes a head circumference band 20 and an adjuster 21 fixed to the head circumference band 20. The head circumference band 20 is fixed to the helmet body 1 to connect the helmet body 1 and the adjuster 21. The head circumference band 20 can be adjusted according to the size of the head circumference to be suitable for people with different head circumferences.

[0033] In some embodiments, after the driver and passenger wear the helmet, the headband 20 is arranged around the periphery of the driver and passenger's head, and the adjuster 21 is located at the back of the driver and passenger's head.

[0034] In some embodiments, the adjuster 21 and the headband 20 are engaged with each other through teeth to adjust the size of the headband 20 .

[0035] In some embodiments, the head circumference band 20 is detachably assembled on the helmet body 1 to facilitate replacement of the head circumference adjuster 2 .

[0038] In some embodiments, the head circumference adjuster 2 is fixed on the lining 11 .

[0039] In some embodiments, the inner lining 11 refers to an internal buffer layer, the main function of which is to absorb the impact of external collisions to protect the head. The inner lining 11 can be made of foam material or fibrous material. The outer shell 12 can be made of harder materials such as plastic or carbon fiber. If an accidental collision occurs, the outer shell 12 is the first line of defense to protect the head and is used to disperse the impact force.

[0040] The head circumference adjuster 2 includes an adjuster 21 and a wearing detection device 22 fixed on the adjuster 21 to detect whether the driver or passenger wears a helmet. The data recording function can also be expanded to realize more intelligent functions.

[0041] The wearing detection device 22 is fixed on the adjuster 21. On the basis of an ordinary helmet, by replacing or adding the head circumference adjuster 2, the helmet can have a wearing detection function, thereby increasing riding safety and saving costs compared to purchasing a new helmet with a detection function. At the same time, it can ensure that when the driver and passenger wear the helmet, the wearing detection device 22 contacts the wearer's head to ensure the accuracy of the detection.

[0042] In some implementations, the wearing detection device 22 includes an infrared sensor 221 and a capacitive sensor 222 to increase the accuracy of detection.

[0043] In some implementations, the wearing detection device 22 may only include an infrared sensor 221 or a capacitive sensor 222 .

[0044] The infrared sensor 221 is a sensor using infrared rays as a medium, and can detect whether an object is close to the driver or the passenger. When the driver or the passenger wears a helmet, the infrared sensor 221 is close to the driver or the passenger's head, and it can be determined that the driver or the passenger wears a helmet.

[0045] The capacitive sensor 222 is a conversion device that uses various types of capacitors as sensing elements to convert the measured physical quantity or mechanical quantity into a capacitance change. It is widely used in the measurement of displacement, angle, vibration, speed, pressure, etc. In the present embodiment, after the helmet is worn correctly, the capacitive sensor 222 is close to the head of the driver and passenger, and has a certain pressure. Optionally, the capacitance value of the capacitive sensor can increase as the pressure increases, or it can decrease as the pressure decreases. Taking the capacitance value of the capacitive sensor increasing as the pressure increases as an example, in the present embodiment, when the capacitance value collected by the capacitive sensor is greater than a threshold value, or continues to be greater than the threshold value for a predetermined time, it indicates that the capacitive sensor 222 is close to the head of the driver and passenger, and it can be judged that the driver and passenger are wearing a helmet.

The power consumption of the helmet when working continuously for 24 hours is about 0.24mAh, and the power consumption is relatively low.
