Step S2: and calculating impact energy according to the collision acceleration signal. Specifically, the controller 40 analyzes the acceleration signal and calculates the speed change and the impact energy of the vehicle.
Step S3: and comparing the impact energy with preset impact energy and judging the corresponding collision grade. Specifically, the controller 40 compares the calculated impact energy with a preset impact energy and determines a corresponding collision level, and transmits a control signal of the collision level to the cylinder 30.
Step S4: the air cylinder 30 is controlled to apply a corresponding air pressure to the headrest airbag 21 according to the collision grade. Specifically, the air cylinder 30 applies corresponding air pressure to the headrest air bag 21 according to a received control signal, the air cylinder 30 inflates the headrest air bag 21 through an air pipe communicated with the headrest air bag 21, the headrest air bag 21 rushes out through the air bag bursting open 22 due to rapid expansion and rapidly deploys by breaking the tearing area 121, at the moment, the headrest air bag 21 has a special modeling design that the middle-lower area of the seat headrest 11 and the top area of the seat backrest 12 can be covered after being deployed, the first supporting part 211 supports the head of the passenger, the second supporting part 212 supports the shoulder of the passenger, the convex part 213 effectively supports the neck of the passenger, the wrapping part 214 protrudes and wraps the neck of the passenger due to two stressed sides being high, the left and right neck movement of the passenger can be prevented, the back surface of the first supporting part 211 tightly adheres to the middle-lower part of the seat headrest 11, the back surface of the second supporting part 212 tightly adheres to the top of the seat backrest 12, and plays a certain supporting role for the convex portion 213 of the headrest airbag 21.
Further, the method further comprises: different impact energies are set in advance to a plurality of collision levels. Specifically, the air pressures of the headrest airbags 21 corresponding to different impact energies are tested in advance, and then the different impact energies are set to a plurality of collision levels, which are different from each other in correspondence to the air pressures of the headrest airbags 21. In this embodiment, the collision zone is divided into three collision levels, i.e., a high collision level corresponds to the impact energy within one range value, a medium collision level corresponds to the impact energy within another range value, and a low collision level corresponds to the impact energy within another range value. The air pressures of the three collision grades corresponding to the headrest air bag 21 are respectively high air pressure, middle air pressure and low air pressure, and the air pressure for filling the headrest air bag 21 can be controlled through the high gear, the middle gear and the low gear of the air cylinder 30. Of course, the collision zone may be divided into more levels according to the impact energy, or a calculation formula of the impact energy and the air pressure of the airbag may be set, but not limited thereto.
Specifically, when the impact energy is in a low-level collision level, the head and neck movement tendency of the passenger is relatively mild, the controller 40 controls the cylinder 30 to open the low-gear switch, the inflation speed is relatively slow, the headrest airbag 21 is slowly deployed, and the head is relatively comfortable and mild after contacting the head; when the impact energy is in a middle-grade collision grade, the head and neck movement tendency of the passenger is also strengthened, the controller 40 controls the air cylinder 30 to open the middle-grade switch, the inflation speed is increased, and the headrest air bag 21 is rapidly unfolded and plays a supporting role for the head and neck of the passenger; when the impact energy is in a high-level collision level, the head and neck movement tendency of the passenger is also aggravated, the controller 40 controls the cylinder 30 to open the high-level switch, the headrest airbag 21 is rapidly inflated and expanded, and the head of the passenger is guaranteed to be timely and effectively supported. According to the impact energy, the unfolding condition of the headrest airbag 21 and the head and neck movement trend of the passenger need to be ensured to be matched, so that the optimal protection effect is ensured, and the comfort and the safety of the protection process are ensured.
