Description

A kind of auto side-crash energy-absorbing box
Technical field
The present invention relates to a kind of auto side-crash energy-absorbing box.
Background technology
Along with the development of society, automobile is not the most unreachable luxury goods, and increasing people start to have genus Automobile in oneself.And increasing along with automobile quantity, vehicle accident generating capacity is also significantly rising.Due to automotive dead weight one As at about 1.5 tons, and travel speed is the lowest, the most once has an accident, it is more likely that make health or vehicle itself Become huge damage.
Generally, the destructive maximum during Vehicular impact relatively travelled, therefore energy-absorption box is often installed in vapour On the front bumper of car, alleviate vehicle and personnel's impact with this.But in actual accidents, the situation of head-on collision is relatively Few, modal is often side impact, and in the side door of most of automobile is the buffer unit not having energy-absorption box etc, because of Easily passenger is damaged when this has an accident.Existing energy-absorption box is usually connected between front bumper and vehicle frame, will It is placed in car door, and its energy-absorbing effect is the most up to standard, and the side being therefore not particularly suited for car body uses.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing energy-absorption box, the present invention provides the vapour that a kind of energy-absorbing effect is up to standard and safer Car side impact energy-absorbing box.
The present invention solves the technical scheme of its technical problem: a kind of auto side-crash energy-absorbing box, including being arranged on car door Energy-absorption box body between plaque and car body, described energy-absorption box body is a boring and has the four of bottom opening Face body housing, the shape of left and right two sides of this energy-absorption box body is up-small and down-big trapezoidal, described energy-absorption box body The intersection of each side all offers notch, and this notch is arranged on the bottom of each side, and described energy-absorption box is intrinsic A reinforcement it is provided with between upper surface and leading flank.
Further, the bottom surface of described energy-absorption box body extends the some fixed plates of formation laterally, and described fixed plate is opened It is provided with ultrasound wave installing hole.
Further, the drafting angle of the leading flank of described energy-absorption box body is 30 degree, the trailing flank of described energy-absorption box body Drafting angle be 3 degree.
Further, described notch is the notch of inverted U.
Further, the bottom of described energy-absorption box body is provided with some locating convex blocks.
Further, the thickness of described energy-absorption box body is 2.5mm.
Further, described energy-absorption box body is made up of PP.
When the present invention uses, this energy-absorption box body is fixed on automobile door trim, is preferably mounted to and human body On the door trim position, Qianmen that abdominal part, waist are corresponding, and the door trim position, back door corresponding with human abdomen.First lead to during installation Crossing locating convex block centering position, fixed by ultrasound wave installing hole, this mounting means low cost, efficiency is high, and can realize certainly Dynamic metaplasia is produced.
The beneficial effects of the present invention is: 1. simple in construction, easy to assembly, steadiness is good, and actual energy-absorbing effect is obvious;2. PP material is used to make, lower compared to conventional foam material cost, and can recycle, meet environmental protection trend, subtract Few resource ground waste;3. this energy-absorption box is by test, and reliability reaches and exceeds index value.

Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 1~Fig. 5, a kind of auto side-crash energy-absorbing box, including being arranged between automobile door trim 1 and car body Energy-absorption box body, described energy-absorption box body 2 is a boring and the tetrahedron housing with bottom opening, and this energy-absorption box is originally The shape of left and right two sides 3 of body 2 is up-small and down-big trapezoidal, the intersection of each side of described energy-absorption box body 2 All offer notch 4, and this notch 4 is arranged on the bottom of each side, the upper surface in described energy-absorption box body 2 and leading flank Between be provided with a reinforcement 5.
The bottom surface of described energy-absorption box body 2 extends the some fixed plates 6 of formation laterally, and described fixed plate 6 offers Ultrasound wave installing hole 7.It is preferably the bottom surface of this energy-absorption box body and extends 1 fixed plate of each formation towards 3 different directions, one Totally 3 fixed plates, the line of these three fixed plate forms triangle, according to the character of triangle, the arrangement of this fixed plate Both can ensure that the stability of installation, and be able to ensure that energy-absorption box deformation simultaneously when clashing into, rupture, thus absorb rapidly More Impact energy.
In the present embodiment, the drafting angle of the leading flank 8 of described energy-absorption box body 2 is 30 degree, described energy-absorption box body 2 The drafting angle of trailing flank 9 is 3 degree.The setting of drafting angle makes product be easier to the demoulding in process of production, and makes raw The energy-absorption box that output is come is with corresponding angle, during deformation fracture, it is possible to lay down the energy of more shock.
In the present embodiment, described notch 4 is the notch of inverted U.The notch of this inverted U can concentrate absorption more to hit Hit energy, and more equalize during deforming, rupturing, it is ensured that using effect.
In the present embodiment, the bottom of described energy-absorption box body 2 is provided with some locating convex blocks 10, it is simple to fast aligning during installation Position.
In the present embodiment, the thickness of described energy-absorption box body 2 is preferably 2.5mm, and thickness is the thinnest does not reaches energy-absorbing standard, mistake The thick degree that can affect deformation when receiving and clashing into, rupture again, causes using effect the best.
In the present embodiment, described energy-absorption box body 2 is made up of PP, lower compared to conventional foam material cost, and And can recycle, meet environmental protection trend, reduce the waste of resource ground.
When the present invention uses, this energy-absorption box body is fixed on automobile door trim.Convex is first passed through during installation Block centering position, is being fixed by ultrasound wave installing hole, this mounting means low cost, and efficiency is high, and can realize automated production.
The inspection center that the automobile side door-plate being fixed with energy-absorption box body is taken Howa Machinery, Ltd of Japan is carried out Detection, obtain following CAE resolve account:
In conjunction with upper table and Fig. 6, Fig. 7, it can be seen that when the energy-absorption box of the present invention is arranged on the front door corresponding with human chest When position and the Rear Door position corresponding with human body waist, test result shows and does not reaches test target value;Suction as the present invention Can be arranged on the front door position corresponding with human abdomen, waist by box, and during corresponding with human abdomen Rear Door position, Test result shows can reach test target value.Therefore, this energy-absorption box is preferably mounted to corresponding with human abdomen, waist On front door position, and the Rear Door position corresponding with human abdomen.
