Fig. 3 is a full motion process of the lightning protection assembly mechanism when the whole vehicle is impacted by explosion. From the analysis of the whole vehicle, the whole vehicle is divided into two stages of rising (explosion impact) and falling (gravity action), the two stages are reflected to the lightning protection component mechanism and respectively correspond to the rising stage from a to c and the falling stage from d to f of the lightning protection component. As shown in fig. 3, a in fig. 3 is an initial state of the lightning protection assembly, when the vehicle body is impacted by explosion, the entire vehicle is subjected to an upward impact acceleration, the acceleration is filtered and then a part of the impact acceleration is transmitted to the seat, the seat moves downward relative to the entire vehicle, at this time, the lightning protection assembly mechanism starts to intervene due to the impact, first, the first coil spring 30 starts to absorb shock and deform (as shown in b in fig. 3), and if the received impact force is large enough, the second coil spring 50 is triggered to intervene and start to absorb shock and deform (as shown in c in fig. 3) until the received impact force is completely absorbed. At the moment, the seat and the whole vehicle move upwards at the same speed, and the whole vehicle performs deceleration movement upwards because the whole vehicle is always subjected to gravitational acceleration, when the whole vehicle moves to the highest point, the speed is zero, and the vehicle starts to move downwards in a free-fall mode, at the moment, the seat and the passengers are in a weightless state in the whole vehicle, the gas spring 40 can spring the seat and the occupant to the initial position (d in fig. 3) by its own resilience due to the weight loss, the gas spring 40 springs the seat to the initial position before the vehicle hits the ground, so that there is enough space for the seat to descend when the vehicle hits the ground, when the whole vehicle freely falls and impacts the ground, the whole vehicle can be impacted again on the ground, the impact can be transmitted to the seat through the whole vehicle on the ground, the seat can be impacted, the lightning protection assembly mechanism can intervene again (as shown in e and f in fig. 3), and the motion process is similar to that in the ascending stage. The matching use of the gas spring and the coil spring is adopted to achieve the shock absorption function, and the lightning protection component achieves the maximum shock absorption function in a limited space through the rebound effect of the gas spring.
