Abstract
The utility model relates to a front crossbeam assembly structure, and solves the problems that a common front crossbeam assembly structure has defects in the aspect of protecting pedestrians. The front crossbeam assembly structure includes a front crossbeam outer plate and a front crossbeam inner plate, the section of the front crossbeam outer plate is ladder-shaped, the section of the front crossbeam inner plate is shaped like the Chinese character 'ji', and a groove is arranged on the surface of the front crossbeam inner plate. The front crossbeam assembly structure has the advantages that the external strength of the front crossbeam is reduced, so that the deformation energy adsorption can be easier; moreover, the displacement of a human body knee joint is reduced in comparison with buffering foam, so that a pedestrian can be well protected; and the strength of the front crossbeam inner plate is improved, so that the front crossbeam inner plate cannot be deformed easily, a longitudinal beam crushing area can adsorb energy completely before the rear part of a longitudinal beam is bent, and the front crossbeam assembly structure can achieve good collision effect.
Description
Technical field
The utility model relates to a kind of automobile component, relates in particular to a kind of front cross rail assembly structure that can better protect the pedestrian.
Background technology
In the present car load design, in order to guarantee the effect of head-on crash and 40% offset collision, the front cross rail assembly is general to adopt two high tensile steel plates to be welded into an osed top die cavity.In order to carry out protection to the pedestrian; can between front cross rail assembly and bumper/spoiler, add one deck bump rubber; but still there is deficiency in this structure aspect pedestrian protecting; the buffering foam is because rigidity is not enough; can cause dummy's knee joint place displacement to surpass laws and regulations requirement easily toward the shrinkage distortion of front cross rail direction.Aspect 40% offset collision, because the front cross rail assembly adopts two high tensile steel plates, increased complete vehicle quality, if complete vehicle quality is excessive, the too early bending of front cross rail assembly meeting forms torque to left longeron then, causes the longeron bending, conquassation district energy-absorbing deficiency.China's utility model patent 200920309195.2 discloses a kind of front cross rail of automobile, and it comprises inner panel and the outside plate that is fixed together, and the support of at least one rigidity is installed between inner panel and the outside plate, and this support is several fonts.This structure has been improved the conquassation performance of front cross rail; the distortion in cabin when alleviating head-on crash; when collision; can allow support produce the stack distortion; reduce whole front cross rail after the amount of moving; guaranteeing the living space of personnel on chaufeur and the dress circle, but this device when not considering to clash into to pedestrian's protection, can not form good protection to the pedestrian.
Summary of the invention
The utility model has mainly solved general front cross rail assembly and had not enough problem aspect pedestrian protecting, and a kind of front cross rail assembly structure that can better protect the pedestrian is provided.
Another goal of the invention of the utility model is the problem that has solved the too early bending of front cross rail assembly in the past.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of front cross rail assembly structure, comprise front cross rail outside plate and front cross rail inner panel, the cross section of described front cross rail outside plate is echelon form, the cross section of described front cross rail inner panel is several fonts, and the surface of front cross rail inner panel is provided with groove.Cancelled the buffering foam that in the past is installed on the front cross rail outside plate in the technical program; it is trapezium structure that the front cross rail outside plate is designed to the cross section; and cancelled groove on the front cross rail outside plate, reduced the intensity of front cross rail outside plate, when the pedestrian is clashed into the car front cross rail; the front cross rail outside plate is the easy deformation energy-absorbing more; protected the pedestrian, in addition, compared with the buffering foam; this front cross rail outside plate has reduced the displacement of human body knee joint, makes the more difficult fracture of pedestrian's shank.The front cross rail inner panel is provided with groove, has strengthened the intensity of front cross rail inner panel, and this makes the front cross rail inner panel not yielding, the longitudinal-beam crushing district can be before the bending of longeron rear portion abundant energy-absorbing, obtain good collision effect.
As a kind of preferred version of such scheme, the thickness of described front cross rail outside plate is 0.6mm ~ 0.7 mm, and the thickness of described front cross rail inner panel is 1.8mm ~ 2.0mm.Attenuate the thickness of front cross rail outside plate, not only reduced the intensity of front cross rail outside plate, and reduced complete vehicle weight, improved the car load safety, increased the thickness of front cross rail inner panel, strengthen the intensity of front cross rail inner panel.
As a kind of preferred version of such scheme, described front cross rail inner panel adopts high tensile steel plate to be stamped to form.Make the front cross rail inner panel more not yielding.
The utility model has the advantages that and reduced the exterior intensity of front cross rail that feasible more easy deformation energy-absorbing is compared the displacement that the buffering foam has reduced human body knee joint in addition, has well protected the pedestrian; Strengthened the intensity of front cross rail inner panel, made the front cross rail inner panel not yielding, the longitudinal-beam crushing district can be before the bending of longeron rear portion abundant energy-absorbing, obtain good collision effect.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to cutaway view.
The specific embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.
Embodiment:
A kind of front cross rail assembly structure of present embodiment as depicted in figs. 1 and 2, comprises front cross rail outside plate 1 and front cross rail inner panel 2, and the cold-reduced sheet that this front cross rail outside plate employing trade mark is 0.7/DC04 is made, and its thickness is 0.7mm.The front cross rail inner panel employing trade mark is that the ultrahigh-strength steel plates of 1.8/BTR165 is made, and its thickness is 1.8mm.The cross section of front cross rail outside plate is an echelon form.The cross section of front cross rail inner panel is several fonts, and the front cross rail outside plate is arranged on prelaminar part in the front cross rail, fixes by welding and front cross rail inner panel, in order to strengthen the intensity of front cross rail inner panel, at the square groove 3 that is provided with of front cross rail inner panel surface upper edge length.
Specific embodiment described herein only is that spirit of the present invention is made casehistory.The technical personnel of the technical field of the invention can be made various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as front cross rail outside plate, front cross rail inner panel, groove morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
