[0002] With the progress of society and the development of the economy, the automobile industry has developed rapidly, the number of vehicles on the road has increased, and traffic accidents have occurred frequently. In some car accidents, the driver is mainly hit from the side. Although there are protections of doors and frames, there is a lack of direct protection and buffer structure. The glass fragments or broken parts after the collision can easily cause damage to the side of the patient's head. In addition, when the vehicle hits sideways, the driver's head will swing accordingly, and the frame will deform and bulge, which may cause the patient's head to be hit from the side, causing serious harm to the driver.
