Abstract
The utility model provides an energy-absorbing structure for an automobile front cross beam, belongs to the technical field of mechanics, and solves the problem that the automobile body is damaged due to insufficient energy-absorbing capacity of the front cross beam in the prior art. The energy-absorbing structure comprises a front cross beam and an energy-absorbing case arranged between the front cross beam and a front longitudinal beam; and is characterized in that the front cross beam is single plate made of a steel plate, and the front end of the energy-absorbing case is fixedly connected with the front cross beam. The energy-absorbing structure reduces the space occupied by the front cross beam, lengthens the length of the energy-absorbing case to increase the load capable of absorbed and converted by the energy-absorbing case, ensures gentle and sufficient energy absorption after collision of the front cross beam, provides higher survival probability to passengers, and reduces the damage to the automobile as much as possible.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of automobile front cross rail, particularly a kind of endergonic structure of automobile front cross rail.
Background technology
Front cross rail is horizontally installed on the front end of automobile, destroy for fear of vehicle structure being produced when the front end crash, added deformation element, it is energy-absorbing box structure, the energy-absorbing box is that the box body structure that rectangular thin-walled element is made is made, is generally to steel, aluminium or plastics, it can be put together by the sheet material shell that compacting forms, also can be integrally formed by the section bar of extruding.Energy-absorbing box operated by rotary motion is between automobile longitudinal girder and front cross rail, and it absorbs because the kinetic energy that collision causes is converted into work of deformation with kinetic energy in this process, can avoid making when surpassing a critical load level vehicle body generation gross distortion thus.
At present, some minicar in the time of body drawing because space constraint, the energy-absorbing box is very short, cause the conquassation fully when head-on crash of energy-absorbing box, thereby influenced the collision safety performance of car load, when automobile bumps, will produce serious impact and cause the occupant to come to harm the crew module.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind ofly more can fully be out of shape and energy-absorbing, has good conversion load ability, and the endergonic structure of simple and practical automobile front cross rail.
The purpose of this utility model can realize by following technical proposal: a kind of endergonic structure of automobile front cross rail, comprise front cross rail and be installed in front cross rail and front side member between the energy-absorbing box, it is characterized in that, described front cross rail is the single plate structure that sheet material is made, the front end of energy-absorbing box and front cross rail Joint.
By the front cross rail transformation of the way is become single plate structure, reduced the thickness and the volume of front cross rail in the technical program,, improved energy-absorbing effect, reduced the impaired of vehicle body to increase the length of energy-absorbing box.
In the endergonic structure of above-mentioned a kind of automobile front cross rail, described front cross rail has the transverse concave groove structure, the opening of its groove direction in car, the bottom Joint of the front end of energy-absorbing box and groove.
In the endergonic structure of above-mentioned a kind of automobile front cross rail, the front end of described energy-absorbing box be provided with one with front cross rail be fixedly coupled plate.
In the endergonic structure of above-mentioned a kind of automobile front cross rail, described energy-absorbing box is by two affixed forming of notch shape box plate dislocation.
In the endergonic structure of above-mentioned a kind of automobile front cross rail, described energy-absorbing box is the box like structure that a block plate panel beating is made.
In the endergonic structure of above-mentioned a kind of automobile front cross rail, the flanging place of described energy-absorbing box is shaped on and induces the hole or induce groove.The technical program is provided with on the energy-absorbing box and induces the hole or induce groove, and with respect to traditional energy-absorbing box, its distortion is more abundant, and energy-absorbing effect is more superior.
In the endergonic structure of above-mentioned a kind of automobile front cross rail, be provided with the energy-absorbing buffering material in the described energy-absorbing box.
Compared with prior art, interior plate structure in this structure cancellation front cross rail, the double plate structure that changes the front cross rail in original technology is a single plate structure, has reduced the shared space of front cross rail, the length of the energy-absorbing box that extended, the load that makes the energy-absorbing box can absorb conversion increases, can ensure front cross rail after being clashed into, energy-absorbing is mild, abundant, for the occupant provides bigger living space, the damage that simultaneously alleviates vehicle as much as possible is to reduce the later period maintenance expense.With it simultaneously, the front cross rail that uses veneer to make in the technical program can economical with materials, and alleviates integrally-built weight.
