In order that the above-recited objects, features and advantages of the present utility model will be more clearly understood, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
Example 1
A vehicle crash cushion apparatus as shown in fig. 1 to 3, comprising: the anti-collision main beam 2, anti-collision auxiliary beam 5, anti-collision main beam 2 rear side is equipped with the energy-absorbing box, and be connected fixedly through energy-absorbing box and automobile body longeron 1, anti-collision auxiliary beam 5 is fixed to be set up in the place ahead of anti-collision main beam 2, be equipped with a plurality of fixed plates 7 and a plurality of damping plates 8 between anti-collision auxiliary beam 5 and the anti-collision main beam 2, the even setting of fixed plate 7 is between anti-collision main beam 2 and anti-collision auxiliary beam 5, damping plate 8 is the bending plate of vertical setting, covering 6 fixed mounting is on anti-collision auxiliary beam 5, still be equipped with buffer structure 9 between covering 6 and anti-collision auxiliary beam 5, anti-collision auxiliary beam 5 can adopt the structure of metal box.
Specifically, when a vehicle encounters a frontal collision, the vehicle firstly collides with the covering part 6, the covering part 6 of the vehicle body does not have the function of buffering and absorbing energy, the auxiliary anti-collision beam 5 firstly bears the impact force of the collision, after receiving the impact force, the acting force on the auxiliary anti-collision beam 5 can be transmitted to the fixing plate 7 and the damping plate 8, and under the condition of smaller impact force, the rigidity of the fixing plate 7 and the auxiliary anti-collision beam 5 can play a good role in anti-collision, so that other parts of the vehicle at the rear part of the vehicle are protected; when the impact force is large, the anti-collision auxiliary beam 5, the fixed plate 7 and the damping plate 8 reduce the impact force of collision by utilizing deformation energy absorption, if the impact force of collision is very large, after the anti-collision auxiliary beam 5, the fixed plate 7 and the damping plate 8 are damaged, the impact force can be transmitted to the anti-collision main beam 2, and at the moment, the energy absorption box at the rear side of the anti-collision main beam 2 absorbs energy and buffers the impact force of collision is further reduced.
The energy-absorbing box comprises a shell 3, a straight sleeve 4 and a buffer 10, wherein the straight sleeve 4 is positioned in the shell 3, the side wall of the straight sleeve 4 is a folded plate side wall, the straight sleeve 4 can be gradually bent and compressed when encountering impact, and part of energy can be absorbed by the straight sleeve 4 and the shell 3 in the process.
