As shown in fig. 1 to 3, the utility model provides a vehicle energy-absorbing device 100 sets up between crashproof roof beam and automobile body, include: the automobile anti-collision device comprises a supporting frame 10 and a deformation inserting plate 20, wherein the deformation inserting plate 20 penetrates through the supporting frame 10 and absorbs kinetic energy of a vehicle after collision through deformation, and damage of the vehicle caused by collision is reduced.

Specifically, the supporting frame 10 includes a first bottom plate 11 and a second bottom plate 12 that are parallel to each other, and at least one side plate 13 connected between the first bottom plate 11 and the second bottom plate 12, at least one insertion hole 111 is formed in the first bottom plate 11 along a direction perpendicular to the first bottom plate 11, and an arc abutting portion 121 is disposed on one side of the second bottom plate 12 close to the first bottom plate 11;

the deformation insert plate 20 is inserted into the insertion hole 111 and abuts against the arc abutting portion 121, and when the deformation insert plate 20 moves towards the second bottom plate 12, one end of the deformation insert plate 20 abutting against the arc abutting portion 121 is bent and deformed under the guiding action of the arc abutting portion 121.

As shown in fig. 4, the deformable insert plate 20 abuts against the arc abutting portion 121, and when the deformable insert plate 20 moves toward the arc abutting portion 121, one end of the deformable insert plate 20 abutting against the arc abutting portion 121 is deformed and bends toward a lower side of the arc abutting portion 121, so that the deformable insert plate 20 is deformed while being attached to the arc structure, thereby absorbing kinetic energy of the vehicle and reducing impact of vehicle collision on the vehicle frame.

It is worth mentioning that, as shown in fig. 5, after the transformable inserting plate 20 is completely sunk into the supporting frame 10, the impact beam and the car body press the supporting frame 10, and at this time, the side plate 13 and the transformable inserting plate 20 are simultaneously transformed to absorb the kinetic energy of the car. The deformed inserting plate 20 forms an annular structure in the supporting frame 10 after being deformed, and when the first bottom plate 11 and the second bottom plate 12 abut against the annular structure, the annular structure continues to be deformed for the second time, so that kinetic energy of the vehicle is further absorbed. It can be understood that the vehicle energy absorption device 100 can effectively reduce the impact force caused by vehicle collision and reduce the damage caused by an accident after absorbing energy in various ways.

Preferably, with reference to fig. 1 to 3, two insertion holes 111 are formed in the first bottom plate 11, a deformation insertion plate 20 is disposed in each insertion hole 111, two arc-shaped abutting portions 121 are correspondingly disposed on the second bottom plate 12, and each deformation insertion plate 20 abuts against one arc-shaped abutting portion 121.

It can be understood that the two opposite side plates 13 can provide better support for the support frame 10 when the support frame 10 is deformed, and can make the first bottom plate 11 and the second bottom plate 12 uniformly stressed when the support frame 10 is deformed, so as to keep the first bottom plate 11 and the second bottom plate 12 parallel to each other.

Further, the side plate 13 is perpendicular to the second bottom plate 12.

Preferably, at least one groove 131 is formed on the side plate 13 close to the deforming insert plate 20, and the groove 131 extends in a direction parallel to the first bottom plate 11.

It can be understood that the provision of the recess 131 in the side plate 13 enables the side plate 13 to protrude away from the deforming insert plate 20 when deforming, thereby avoiding the side plate from being squeezed with the deforming insert plate 20 and affecting the deformation of the deforming insert plate 20.

Preferably, the thickness of the first bottom plate 11 is x, and x is more than or equal to 10mm and less than or equal to 15 mm.

It can be understood, so set up, can make first bottom plate 11 play the effect of direction to warping picture peg 20, it needs to explain, braced frame 10 is fixed in respectively on frame and crashproof roof beam with warping picture peg 20, and make second bottom plate 12 and warp picture peg 20 mutually perpendicular, nevertheless when colliding, warp picture peg 20 and take place deformation, it is relatively poor to make warp picture peg 20 take place to buckle easily and lead to the deformation effect, and then influence the absorption of kinetic energy, so can have the guide effect to warping picture peg 20 through thickening first bottom plate 11, the effect of the deformation energy absorption of picture peg 20 is warp in the improvement.

It is worth mentioning that when the deformation insert plate 20 is arranged in a manner that the thickness gradually decreases from the end far away from the second bottom plate 12 to the end near the second bottom plate 12, a gap is formed between the first bottom plate 11 and the deformation insert plate 20, but a certain guiding function can still be achieved.

Preferably, a connecting plate 30 is arranged at one end of the deformation insert plate 20 away from the second bottom plate 12, and the connecting plate 30 is arranged perpendicular to the deformation insert plate 20.

It will be appreciated that the deforming effect of the deformer plate 20 is enhanced by providing the connecting plate 30 and attaching the connecting plate 30 to the frame or impact beam so that the deformer plate 20 is perpendicular to the surface to which it is attached.
