FIG. 2 is a schematic perspective view of the overall structure of the present utility model;
FIG. 3 is a schematic view of the inner and outer cushioning layers of the present utility model detached from the pre-crash beam.
Detailed Description
The utility model will be further described with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, an automobile anti-collision beam comprises an anti-collision beam body 1, a pre-collision beam 2 is arranged at a side interval of the anti-collision beam body 1 towards a head of a vehicle, the length direction of the pre-collision beam 2 is arranged along the width direction of the vehicle body, a buffer zone 3 in the front-rear direction of the vehicle body is included between the pre-collision beam 2 and the anti-collision beam body 1, the automobile anti-collision beam is used for providing space for the invagination deformation generated by the impact of the pre-collision beam, the direct impact on the anti-collision beam body after the bending invagination of the pre-collision beam is avoided, the pre-collision beam 2 comprises a plurality of continuous and integrated collision sections in the length direction of the beam body, the collision sections refer to a section of the beam body positioned on the pre-collision beam, for example, two side sections, a middle section and the like can be divided, any one of the collision sections face the invagination deformation in the buffer zone 3 under the impact state, the pre-collision beam 2 is arranged in front of the anti-collision beam body, the impact force acts on the pre-collision beam 2, so that the pre-collision beam is stressed and the invagination deformation is enabled to be bent to a bending state, the extent is also is avoided, the impact is received through the buffer zone, and the impact force is reduced, and the impact force is directly stressed by the impact force is relieved when the impact force is relieved to the impact force is directly from the impact force of the impact body.
The rigidity of the pre-collision beam 2 is smaller than that of the anti-collision beam body 1, the impact strength of the pre-collision beam 2 is 20% -35% of that of the anti-collision beam body, and plastic, wood strips or low-hardness metal and the like are adopted, so that pedestrians or electric vehicles can unload and buffer force when impacting the anti-collision beam body 1 through the pre-collision beam.
