4Kg, according to formula:
F＝μ·N
Even get μ is 0.1, and the friction force in this device between engine bed and the guide rail also reaches 4 * 10
3Kg, and the impact force overwhelming majority is to act on horizontal direction, can not give initial velocity along the guide rail direction of driving engine, in addition, the deadweight of driving engine approximately is between 50kg～200kg, and therefore, driving engine also can not rely on the gravity of self to move along the guide rail direction.Therefore, in the process that automobile bumps, the situation that most probable occurs is that driving engine can not produce motion in the guide rail direction, and on the contrary, driving engine still can be charged into passenger compartment under the effect of impulsive force.
As seen, realize making in the automobile collision procedure purpose of driving engine by the expected trajectory motion, the impact when only depending on collision and the gravity of driving engine are irrealizable, also must provide a kind of external force, by the effect of this power, make the deformation position arrival engine location of vehicle body structure in the collision process just can allow driving engine leave original position by desired trajectory in advance before.
Summary of the invention:
It is a kind of in the frontal crash of vehicles process that the purpose of this utility model is to provide, the deformation position of vehicle body structure just can allow driving engine leave original position by desired trajectory in advance before arriving driving engine, and the driving engine of avoiding charging into passenger compartment injury occupant is dodged mechanism.
