State cushion side and be provided with multigroup spacing hole, described baffle plate one end both sides are respectively connected with shock-absorbing connection, the shock-absorbing connection one
Side is connected with connector, and the connector side is evenly arranged with multigroup fixing hole, and the connector is connected by fixing hole
There is a longeron, the junction of the beam body and cushion is internally provided with surrounding activity outside multigroup telescopic mast, and the telescopic mast
Helical spring is connected with, the beam body is provided with multigroup hydraulic cavities close to cushion side, and the beam body is connected by hydraulic cavities
Telescopic mast.
It is preferred that, in order that the impulsive force that collision is produced obtains effective attenuation at shock-absorbing connection, reduce the shadow to longeron
Ring, the shock-absorbing connection is internally provided with energy-absorbing housing.
It is preferred that, in order that telescopic mast can freely stretch inside hydraulic cavities, it can be stretched when hitting and play slow
The effect of punching, is movably connected between the telescopic mast and hydraulic cavities.
It is preferred that, in order that beam body is more solid, impulsive force can be distributed to both sides when being hit, it is not easy to become
Shape, the contour structures of the beam body are set in circular arc.
It is preferred that, in order that shock-absorbing connection is firmer, possess the ability for preferably absorbing impulsive force, the energy-absorbing housing
Inside is set in multi-layer honeycomb shape.
It is preferred that, in order that collision prevention girders with multi-faceted protection longeron can make that longeron can be protected not at front and oblique angle
It is knocked, the length of the beam body is more than the distance between two longerons.
The beneficial effects of the invention are as follows：By connecting cushion in beam body side, and added between beam body and longeron
Shock-absorbing connection, when making car collision, impact first passes around cushion, telescopic mast and spiral between cushion and beam body
Spring is slowed down and absorbed to impulsive force, reduces dynamics of the impulsive force to beam body, protects beam body, and reduction beam body becomes
The probability of shape.The honeycombed energy-absorbing housing that impulsive force is entered inside shock-absorbing connection, shock-absorbing connection by beam body enters to impulsive force
Row absorbs, and impulsive force is decayed inside shock-absorbing connection, reduces the impact to longeron, improves the general safety of vehicle
Property, the personnel of vehicle interior are protected, the loss of collision belt is reduced.
