Abstract
The utility model provides a reinforcement structure for a posterior segment of an automobile front rail, which belongs to the technical field of machines, and can solve the problem of large deformation of a passenger compartment during the collision due to insufficient rigidity of the existing posterior segment of the automobile front rail. The improved reinforcement structure for the posterior segment of the automobile front rail comprises the posterior segment of the front rail and an inner reinforcement beam which is fixedly connected therewith, and is characterized in that a reinforcement beam is arranged between the posterior segment of the front rail and the inner reinforcement beam. The reinforcement structure, the posterior segment of the front rail and the inner reinforcement beam constitute the whole reinforcement structure, thereby ensuring the safety of drivers and passengers, and having the advantages of simple structure, and convenience in production and installation.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of automobile front side member, particularly a kind of additional strengthening of automobile front side member back segment.
Background technology
Along with rapid economic development, living standards of the people are greatly improved, and automobile has entered huge numbers of families as a kind of important vehicle, and people have also had more and more higher demand for the safety performance of automobile.
One, front rail structure is installed in the both sides of vehicle in the machinery space along the longitudinal in the automobile, supporting driving engine and change-speed box, and provides installing space for it.
In the NCAP evaluation test, crew module's rigidity and occupant injury have direct relation, and crew module's rigidity greatly then cabin body is out of shape for a short time in collision, and occupant's injury will correspondingly reduce, and occupant's living space just is guaranteed like this.The rigidity of front side member back segment is one of important indicator that guarantees crew module's integraty, and the size of front side member back segment rigidity directly influences the deflection of cabin body in the head-on crash process.Body structure can deform in the more weak position of intensity ratio in head-on crash, existing front side member back segment structural strength a little less than, increased the risk that dash shield is invaded to the crew module, the danger coefficient also corresponding increase of occupant's shank injury.In CAE emulation collision model, a little less than the front side member back segment structural strength, cause the dash shield bottom very big to crew module's intrusion amount, can not satisfy the security development target.
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 of simple in structure, additional strengthening of automobile front side member back segment safely and effectively.
The purpose of this utility model can realize by following technical proposal: a kind of additional strengthening of automobile front side member back segment, comprise front side member back segment and the interior strength beam affixed with it, it is characterized in that, be provided with a strength beam between described front side member back segment and the interior strength beam.
In the technical program by will be provided with on the front side member one with the front side member back segment and in the affixed strength beam of strength beam structure, this strength beam and front side member back segment and interior strength beam three constitute a single-piece additional strengthening, promptly guaranteed the conformability of the back segment intensity of front side member, kept away and exempted from longeron in the weak excessively problem of back segment intensity.
In above-mentioned a kind of automobile front side member additional strengthening, be shaped on reinforced rib on the described strength beam.By on strength beam, setting up reinforced rib,, improve its crashworthiness in the technical program to strengthen the energy-absorbing effect of strength beam.
In above-mentioned a kind of automobile front side member additional strengthening, described strength beam is an ellbeam, and it has the cross section of U-shaped from front to back.The technical program adopts the strength beam with U-shaped cross section, is convenient to match with the back segment and the interior strength beam of front side member.
In above-mentioned a kind of automobile front side member additional strengthening, described strength beam is stacked between front side member back segment and the interior strength beam.
In above-mentioned a kind of automobile front side member additional strengthening, described strength beam and front side member back segment and interior strength beam are fixing by welding.In the technical program, only need get final product by spot-welded on when mounted at the solder joint that strength beam and relevant position on the strength beam in the back segment of relevant front side member reaches are shaped on.
In above-mentioned a kind of automobile front side member additional strengthening, described strength beam is structure as a whole.
Compared with prior art, the improvement of this structure does not influence the relation of front side member and interior strength beam and other part of longeron, also no effect on longitudinal-beam and the manufacturing of before enclosing other part, simple in structure, be convenient to produce, aspect installation, only need to get final product with this position associated part spot welding, and by improving strength beam, longeron back segment additional strengthening has constituted unified integral body, the part no longer occurs and crosses weak and phenomenon that cause conquassation to be out of shape.In head-on crash, strengthened crew module's rigidity by improving strength beam structure in the front side member, reduced the deflection of dash shield bottom, guaranteed crew module's space in the collision process, reduced occupant's injury.
Description of drawings
Fig. 1 is a mounting structure scheme drawing of the present utility model.
Fig. 2 is the structural representation of strength beam of the present utility model.
Fig. 3 is the left view of Fig. 2.
Among the figure, 1, the front side member back segment; 2, strength beam; 3, interior strength beam; 4, reinforced rib.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
With reference to accompanying drawing, front side member back segment 1 is provided with strength beam 2 and the interior strength beam of being made by the high tensile steel plate integrated punching 3.This strength beam 2 is for having the bar ellbeam in the cross section of U-shaped from front to back.
As shown in Figure 2, strength beam 2 is provided with the reinforced rib 4 that strengthens energy-absorbing effect, and the outside face of U-shaped strength beam 2 can fit with front side member back segment 1, and inside face can fit with the bottom of interior strength beam 3.In the time of assembling, strength beam 2 and interior strength beam 3 are stacked on the front side member back segment 1 successively.In the present embodiment, because the length that the front end length of strength beam 2 will be longer than the front side member back segment 1 on the institute fixed position, the front end that is its strength beam 2 extends in the machinery space, and can with the connecting element Joint in the machinery space, constitute a single-piece additional strengthening, strengthen crashworthiness, avoid occurring again front side member back segment 1 part and cross weak and phenomenon that cause conquassation to be out of shape.
Specific embodiment described herein only is that the utility model spirit is made casehistory.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as front side member back segment 1, strength beam 2, interior strength beam 3, reinforced rib 4 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 utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
