Abstract
The utility model relates to a car front longitudinal beam and aims at providing an improvement structure for the car front longitudinal beam, and with the improvement structure, the strength of the car front longitudinal beam is improved. The car front longitudinal beam comprises a front longitudinal beam body extending along the direction of a car body, and comprising a front segment straightened along the direction of the car body, and a downward connecting segment connected with the rear end of the front segment. The car front longitudinal beam has the beneficial effects that when a car is crashed, the crash force is transmitted to the car front longitudinal beam from a front bumper, so that longitudinal collapse happens to the car front longitudinal beam so as to absorb more energy; and a reinforcing rib penetrating through the whole length of the front longitudinal beam body is arranged on the front longitudinal beam body, therefore, the strength of the car front longitudinal beam can be better ensured.
Description
Technical field
The utility model relates to a kind of longeron, particularly relates to a kind of automobile front rail structure.
Background technology
Along with developing of automobile industry; Security requirement to automobile is increasingly high, when automobile meets accident collision, requires auto body that good energy-absorbing effect can be arranged; Guarantee driver and crew's living space to greatest extent, and the distortion that as far as possible reduces operator's compartment is the most basic requirement.Must there be enough strength and stiffness in the cabin of automotive front as the supporting body of parts such as installation driving engine, and automobile is when bumping, and the effect of protecting the occupant is also being born in the cabin.Front side member is positioned at the front portion of car body both sides; Its front end connects bumper/spoiler; Surrounding baffle before the rear end connects; Be the main parts that make up cabin and load, bearing the vehicle body longitudinal force and longitudinal force passed to miscellaneous part such as floor that the while front side member also is the installation matrix of engine assembly, suspension support, radiator bearer etc.Front side member is to guarantee that automobile has the vitals of good collision performance, it through torsional deflection absorb, the attenuate shock energy, to alleviate or to avoid injury to the occupant; Existing girder work is unreasonable; Occur distortion easily, structural strength is little, can not satisfy the requirement of safety.
Chinese patent notification number CN201761542U discloses a kind of automobile front side member, and it comprises the front side member body that is made into integration, and said front side member body is provided with the weakening processing part that produces the compression degeneration.This front rail structure intensity is little, occurs distortion easily, can not satisfy the requirement of safety.
Summary of the invention
The purpose of the utility model is to provide a kind of process automobile front side member stretching and the expansion reinforced rib to improve structure, and the intensity that exists in the background technology is less to solve, the problem of easy deformation and poor stability.
To achieve these goals, the technical scheme of the utility model is: a kind of automobile front side member, comprise the front side member body that extends along the vehicle body direction, said front side member body comprise along the stretching leading portion of vehicle body direction and with the descending linkage section of leading portion rear end bonded assembly.Existing front side member is " bow " type structure, in collision, is easy to elder generation's bending at bow type top, and conquassation power longitudinally becomes component, is unfavorable for the collapse energy-absorption of longeron; Longeron is vertically evened up, improve the problem of longeron elder generation's bending, make longeron that vertical conquassation take place, absorb more energy at present at bow type top.
As preferably, said front side member entity plate face is provided with the reinforced rib that connects its whole length.Reinforced rib can increase the rigidity of rack body, and it is received when clashing into, and is not easy to take place bending.
As preferably, the leading portion of said front side member body is that integral type is connected with descending linkage section.The front side member body is stamped to form by the monoblock steel plate, and intensity is consistent everywhere to make it, and energy-absorbing is even.
As preferably, the silhouette edge of said front side member body is rounding.The silhouette edge of front side member body is made rounding can eliminate stress.
The beneficial effect of the utility model automobile front side member is: longeron is vertically stretching; Improve the problem of longeron elder generation's bending at bow type top; Make the automobile front side member that vertical conquassation take place; Absorb more energy, and on the front side member body, be provided with the reinforced rib that connects its whole length, better guarantee its intensity.
Description of drawings
Fig. 1 is the front view of the utility model automobile front side member;
Label is respectively among the figure: 1. leading portion 2. descending linkage section 3. reinforced ribs.
The specific embodiment
Below through embodiment and combine accompanying drawing that the technical scheme of the utility model is done further to specifically describe.
Embodiment:
As shown in Figure 1, a kind of automobile front side member comprises the front side member body that extends along the vehicle body direction; The front side member body is stamped to form by the monoblock steel plate; Said front side member body comprise along the stretching leading portion 1 of vehicle body direction and with the descending linkage section 2 of leading portion 1 rear end bonded assembly, said leading portion 1 and descending linkage section 2 are provided with the reinforced rib 3 that connects its whole length for integral type is connected on front side member entity plate face; For contour elimination burr and stress, all make rounding to the profile of front side member body in addition.
During use, with the bumper/spoiler of the front end captive joint automobile of the leading portion 1 of this automobile front side member, with the preceding surrounding baffle of the rear end captive joint automobile of descending linkage section 2, when automobile bumped, vertical conquassation took place in longeron, can absorb more energy.
Above-mentioned described specific embodiment only is that the preferable examples explanation is done in the design of the utility model.Any modification of being made within all spirit and principles at the utility model or replenish or be equal to alternatively all should be included within the protection domain of the utility model claim.
