Description

Automobile side impact energy absorption box

Technical Field

The utility model relates to an energy-absorbing box is bumped to car side.

Background

With the development of society, automobiles which were once looked upon by ordinary consumers have gone into thousands of households to become the most popular means of transportation. With the increase of the number of automobiles, the use is wide, and the incidence rate of traffic accidents is greatly increased. Since the self weight of the automobile is generally about 1.5 tons and the running speed is not low, there is a high possibility that a user or the automobile itself is damaged greatly in case of an accident.

In general, since the crash box is most destructive to a traveling vehicle at the time of collision, the crash box is often attached to a front bumper of an automobile to reduce the impact on the vehicle and a passenger in the automobile at a time. In an actual accident, however, there are fewer head-on collisions. The side impact is the most common, and most automobiles are not provided with a buffer device such as a crash box in a side door, so that the automobile body and passengers are extremely easy to be injured in the side impact. The existing energy absorption box is generally arranged between a front bumper and a frame and is placed in a vehicle door, and the energy absorption effect of the energy absorption box is not up to the standard, so that the energy absorption box is not suitable for side impact of a vehicle body.

Disclosure of Invention

In order to solve the above-mentioned problem that exists among the prior art, the utility model provides an effectual and safer car side impact energy-absorbing box of energy-absorbing.

The technical proposal of the utility model for solving the technical problem is that:

an automobile side impact energy absorption box comprises an energy absorption box body arranged between an automobile door trim and an automobile body, wherein the energy absorption box body is of a hollow shell structure with an opening at the bottom, and a plurality of staggered rib positions are arranged inside the energy absorption box body to divide the inside of the shell into a plurality of tetrahedral spaces; and an O-shaped notch is formed at the intersection of the side surfaces of the energy absorption box body.

Furthermore, a plurality of grooves are formed in the bottom of the side face of the energy absorption box body, the grooves extend outwards to form fixing plates, and BOSS column mounting holes are formed in the fixing plates.

Furthermore, a plurality of BOSS columns are arranged at the top of the energy absorption box body.

Furthermore, a plurality of rib positions are arranged between the BOSS column at the top of the energy absorption box body and the top panel.

Further, the thickness of the energy absorption box body is 2 mm.

Further, the energy absorption box body is made of a PP material.

The utility model discloses when using, fix this energy-absorbing box body installation on car trunk side plaque, preferably install the trunk plaque position that corresponds with human belly, waist, make the BOSS post insert energy-absorbing piece hole site earlier during the installation, rethread hot melt BOSS post welding.

The utility model has the advantages that: (1) the structure is simple, the assembly is convenient, the stability is improved by arranging a plurality of staggered rib positions, and the actual energy absorption effect is obvious; (2) the O-shaped notch is arranged at the top end of the energy absorption box, so that more energy is absorbed in a concentrated manner, and the stress is balanced; (3) the material is made of PP material, so that compared with the common foam material, the material has lower cost and can be recycled, the environment-friendly trend is met, and the resource waste is reduced; (4) the reliability of the energy absorption box reaches and exceeds an index value through testing.

Fig. 2 is an installation schematic diagram of the present invention.

Fig. 3 is a top view of the present invention.

The attached drawings are marked with: 1. the energy absorption box comprises an energy absorption box body, 2, a fixing plate, 3, a BOSS column mounting hole, 4, a BOSS column, 5, a second rib position, 6, an O-shaped notch, 7 and a first rib position.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. As shown in fig. 1 to 3, an automobile side impact energy absorption box comprises an energy absorption box body 1 arranged between an automobile door trim and an automobile body, wherein the energy absorption box body 1 is of a hollow shell structure with an opening at the bottom, a plurality of first rib positions 7 which are arranged in a staggered mode are arranged inside the energy absorption box body 1, and the interior of the shell is divided into a plurality of tetrahedral spaces; an O-shaped notch 6 is formed in the intersection of the side faces of the energy absorption box body 1. The O-shaped groove opening 6 can intensively absorb more impact energy, is more balanced in the deformation and rupture processes, and ensures the use effect.

In this embodiment, the bottom of the side surface of the energy absorption box body 1 is provided with a plurality of grooves, the grooves extend outwards to form a plurality of fixing plates 2, and the fixing plates 2 are provided with BOSS mounting holes 3.

In this embodiment, the top of the energy absorption box body 1 is provided with a plurality of BOSS columns 4.

In this embodiment, a plurality of second rib positions 5 are arranged between the BOSS columns 4 on the top of the energy absorption box body 1 and the top panel. The second rib position 5 collides with a sheet metal screw in collision to assist energy absorption, and the condition that the energy absorption is not up to the standard due to the limitation of sheet metal modeling and collision angle is compensated.

In this embodiment, the thickness of the crash box body 1 is 2 mm. The thickness is too thin to reach the energy absorption standard, and too thick can influence the deformation and fracture degree when being impacted, so that the using effect is not good.

In this embodiment, the crash box body 1 is made of PP material. Compared with the common foam material, the cost is lower, and the foam material can be recycled, so that the environment-friendly trend is met, and the waste of resources is reduced.

When the energy absorption box is used, the energy absorption box body is installed and fixed on a side decorative plate of an automobile trunk, preferably the energy absorption box body is installed at the position of the trunk decorative plate corresponding to the abdomen and the waist of a human body, and when the energy absorption box is installed, the BOSS column is inserted into the hole position of the energy absorption block and then welded through the hot melting BOSS column.

The energy absorption device has the advantages that (1) the structure is simple, the assembly is convenient, the stability is improved by arranging the plurality of staggered rib positions, and the actual energy absorption effect is obvious; (2) the O-shaped notch is arranged at the top end of the energy absorption box, so that more energy is absorbed in a concentrated manner, and the stress is balanced; (3) the material is made of PP material, so that compared with the common foam material, the material has lower cost and can be recycled, the environment-friendly trend is met, and the resource waste is reduced; (4) the reliability of the energy absorption box reaches and exceeds an index value through testing.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
