[0002] The working principle of the power-assisted bicycle mainly relies on the coordinated action of three parts: sensors, controllers and motors. When the rider pedals, the sensor is responsible for sensing the force and speed of the pedaling, and transmits the detected speed, pedaling frequency, torque and other information to the controller. The controller calculates and issues instructions to control the operation of the motor, providing additional power, making the riding process easy and labor-saving.

[0003] In daily life, riders need to wear helmets when riding power-assisted bicycles to protect their heads. The interior of the helmet is a helmet cavity to surround the rider's head. A simple grid is arranged in the helmet cavity. The grid can be adjusted to suit the heads of different riders, so that the overall coordination can protect the rider's head from being injured.

[0004] In the prior art, the helmets equipped on power-assisted bicycles simply play a protective role. The overall structural impact resistance of the helmets is poor, and the mesh frame that wraps the head is not stable enough, resulting in poor use effect and difficulty in meeting the safety protection needs of actual riders.
