Abstract
The utility model relates to an automobile longitudinal beam assembly belonging to the field of automobile manufacturing, in particular to an automobile front longitudinal beam. The automobile front longitudinal beam is characterized in that the rear part of a main body is provided with a plurality of parallel power absorbing grooves which are distributed at intervals, and each power absorbing groove extends in the width direction of the main body. The automobile front longitudinal beam can reasonably absorb collision stress after collision to achieve the purpose of protecting a cab and a driver, and the remanufacturing cost is lower.
Description
Technical field
The utility model relates to a kind of automobile longitudinal girder assembly, especially the automobile front side member in the automobile manufacturing field.
Background technology
In recent years, Domestic Automotive Industry and market development are rapid, and the auto-industry volume of production and marketing rises to the No. 1 in the world at present.Along with the increase of national family income and the raising of consumption demand, automotive safety becomes the key factor that influences the decision-making of consumers gradually.How to use low cost to realize that automotive safety becomes each big auto vendor difficult problem.
Analysis through the expert sees, the general safety coefficient of automobile is main still to be decided by structure (having the structure of energy-absorbing and non-deformability step by step).Have the car load of energy-absorbing and non-deformability structure step by step in a flash when what get into an accident, Vehicular body front can be finished maybe many absorbing impact energy, avoid the operator's compartment distortion, and the protection driver and crew avoid traffic accident crisis life.
Main endergonic structure spare when in general front side member is as head-on crash, its energy-absorbing effect directly influence operator's compartment and take advantage of personnel's safety with guarding the emperor.Therefore design a rational front rail structure safety of protecting driver and crew is played decisive role.
Existing front side member energy-absorbing effect is not good especially, causes the operator's compartment distortion of collision back to jeopardize driver and crew's safety easily.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of prior art, and a kind of automobile front side member is provided, and reasonable absorbing impact stress reaches the purpose of protecting driving compartment and driver and crew after collision, and improvement cost is lower.
For solving above technical matters, the technical scheme of the utility model is: the automobile front side member, its difference is: its back body is provided with the energy-absorbing groove that a plurality of parallel interval distribute, and said each energy-absorbing groove extends along the body width direction.
By above scheme, the quantity of said energy-absorbing groove is at least 3.
The contrast prior art, the beneficial features of the utility model is following:
1), this automobile front side member, realize that after collision stress is transmitted in distortion step by step, improved energy-absorbing effect, reach protection driving compartment and driver and crew's purpose.
2), this automobile front side member, improvement cost is lower.
Description of drawings
Fig. 1 is the utility model automobile front side member integral structure scheme drawing.
The specific embodiment
Combine accompanying drawing that the utility model is done further explain through the specific embodiment below.
Please refer to Fig. 1, the utility model automobile front side member, its back body is provided with the energy-absorbing groove 1 that a plurality of parallel interval distribute, and each energy-absorbing groove 1 extends along the body width direction.
Preferably, the quantity of energy-absorbing groove 1 is at least 3.
This project organization is simple, directly is used for after can transforming existing frock producing, and reduces the rectification cycle, reduces improvement cost.Do not have excessive change because of main profile, existing welding jig can directly use.Because this part is by a whole set of die stamping, need change a whole set of die face.
Above content is the further explain that combines concrete embodiment that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
Claims (2)
1. automobile front side member is characterized in that: its back body is provided with the energy-absorbing groove that a plurality of parallel interval distribute, and said each energy-absorbing groove extends along the body width direction.
2. automobile front side member as claimed in claim 1 is characterized in that: the quantity of said energy-absorbing groove is at least 3.
