Abstract
The invention provides a foam metal anti-collision protector. The protector consists of a front panel, guide blocks and guide boxes, wherein, the front panel is connected with the guide blocks; the guide blocks are connected with foam metal filled in the guide boxes; and the guide boxes are connected with a car body. The foam metal anti-collision protector has the characteristics of simple structure, simple manufacturing process, high absorbed energy, lower cost, good protection effect, high utilization ratio of the foam metal and the like, and is convenient for installation, thus being applicable to popularization and application.
Description
Technical field
The invention belongs to a kind of foam metal anti-collision protection device.
Background technology
Vehicle anticollision gear such as Federal bumper or automobile side safety guard, beam etc. can absorb most of energy when the vehicle are subjected to high-speed impact, thereby reach the protection passenger and the safe device that carries cargo.With the Federal bumper is example, and traditional Federal bumper has following several types: 1, adopt steel plate to be stamped to form.This type of bumper/spoiler is along with the raising of the speed of collision, and impulsive force increases sharply, and S. E. A. is very low, causes car body and personnel's injury easily; 2, utilize spring as buffer element.But spring is in that absorbed after the energy will be with same big force reaction and car body almost, with 2 injuries that cause human body or vehicle.3, utilize foamed plastic as energy-absorbing material.Because the intensity of non-metal plastics is very low, therefore after having used a large amount of foams, the energy of absorption still seldom.4, the utility model patent of the patent No. 99221233.2 has been announced a kind of high-energy absorption foam metal bumper/spoiler, and this bumper/spoiler disperses to be provided with the foam metal of fritter energy absorbing between the face guard of the vehicle frame front end and the left and right sides and car body.Because the consumption of foam metal seldom, so the energy that absorbs seldom, and is described by its specification sheets, for the required cost of the protection of the 20Km/h speed of a motor vehicle is more than 100 yuan, and the general automobile protective requirement speed of a motor vehicle is 60km/h, and energy is 9 times of 20km/h, far away the purpose of out of reach energy absorbing.It is inner all with foam metal filled that this patent 200420069769.0 is proposed whole bumper/spoiler, but automobile is when colliding, and is general only stressed at specific stress point, distortion mainly occurs in these points when taking place to collide, and the foam metal of other parts does not have the effect of energy-absorbing.Therefore, though the consumption of foamed aluminium has increased, but greatly reduce the degree of utilization and the protective capability of material.
Summary of the invention
The purpose of this invention is to provide a kind of foam metal anti-collision protection device, utilize foam metal can absorb macro-energy, avoid the deficiency of above-mentioned anticollision device, improve vehicle safeguard function.
The present invention is made up of front panel, orienting lug, orientating box, and front panel is connected with orienting lug, and the foam metal of filling in orienting lug and the orientating box links to each other, and orientating box is connected with car body.
The present invention is simple in structure, easy for installation, have manufacturing process simple, absorb that energy is big, characteristics such as price is lower, protection effect good, foam metal degree of utilization height, suitable popularizing action.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
So-called foam metal 5 is materials of a kind of a large amount of holes that distributed on metallic matrix (as aluminium).The entity metal is in when distortion, along with the increase of deformation quantity, and stressed increasing sharply, foam metal 5 then energy keeps stressed constant (or increasing seldom) under the situation that the large deformation amount takes place.Like this; when foam metal 5 uses as the surge protection material; as long as foam metal 5 is also not densified fully; just can guarantee the stressed level that it can bear that is no more than that maintains all the time of protected object; extraneous impact energy is absorbed by the distortion of foam metal 5, thereby reaches the purpose of protection object.Simply foam metal 5 is made protective device, the low shortcoming of stock utilization is arranged, and the cost of foam metal 5 is higher, thereby causes waste, and protection effect is undesirable.If but can be when vehicle collision, all (or overwhelming majority) foam metals 5 all participate in distortion, then can improve protection effect greatly.
The made vehicle protective device of the present invention is by front panel 1, orienting lug 2, and orientating box 3 is formed, filled and process metal 5 in the described orientating box 3.Described orientating box 3 is connected with car body 4.Described orienting lug 2 can insert orientating box 3 inside.The quantity of the orienting lug 2 that had of device and orientating box 3 and size are according to different vehicle models and difference.
Principle of work
When automobile or other vehicle generation high-speed crash; front panel 1 drives orienting lug 2 along the wall of orientating box 3 internal motion to orientating box 3; because yield-stress ratio car body 4, orientating box 3, the orienting lug 2 of foam metal 5 are little; therefore with crushed foam metal 5; cause foam metal 5 distortion, thereby absorb the kinetic energy when clashing into and protected car body.And the existence of orienting lug 2 and orientating box 3, the energy that can guide different rum points can not form the problem of energy distribution inequality in foam metal.Therefore, the degree of utilization of foam metal 5 is very high.
