Abstract
The utility model discloses a car cracking longeron structure after absorbing energy progressively. The longeron is divided into two parts that are welded together. The front part of the longeron is structure strengthening area while the back part is energy absorbing area. The front part is thicker than the back part as the front part and the back part are designed optimally with different materials. The strengthening elastic is arranged horizontally on the back part of the longeron. The space between the elastics is gradually narrowed from the front to the end. The utility model has the advantages of that the utility model adopts the progressive energy absorbing structure. The thick front part with flexible deformation has good energy absorbing function which is contacted first when rear collision happens. The back part is not as strong as the front part, and is provided with the energy absorbing elastic to get the effect of absorbing energy progressively and make the back part have little deflection or no deflection. The progressive energy absorbing structure gradually deforms no more and absorb energy no more to get well absorbing effect, reduce the damage caused by the collision, elevate the safety of the car in the whole process of collision.
Description
Technical field
The utility model belongs to the automotive body structure technology, particularly the impact beam structure of car.
Background technology
Car collision longeron is the critical component that bears car longitudinal impact power.In order to reach energy-absorbing effect preferably, many car collision longerons are strengthened from the angle that increases the energy-absorbing muscle, have certain effect.But these energy-absorbing muscle are normally equidistantly arranged, and do not consider the vertical variation of impact energy, in addition, before and after the material thickness that existing collision longeron is adopted all is the same, energy-absorbing effect is bad after during collision, and it is serious to cause vehicle body to destroy, and has seriously reduced the vehicle body safety.
Summary of the invention
The purpose of this utility model is at the prior art above shortcomings, proposes a kind of car and collides girder work behind the energy-absorbing step by step, improves back collision energy-absorbing effect, and vehicle body safety is guaranteed.
A kind of car collides girder work behind the energy-absorbing step by step, and it is distributed with reinforced rib on longeron.It is characterized in that longeron is divided into two sections of front and back, be welded to each other to form.Longitudinal beam front section is that structure is strengthened the district, and the longeron back segment is energy-absorbing district step by step, adopts the different thick optimal designs of expecting, the longitudinal beam front section material is thick in the longeron back segment, and is horizontally arranged with reinforced rib on the beam of longeron back segment, and the spacing between reinforced rib reduces after by forward direction gradually.
Described longeron back segment be 1mm, the material of longitudinal beam front section is thick to be 1.8mm.
Advantage of the present utility model is to have adopted endergonic structure step by step, the leading portion material of contact was thick earlier when collided the back, it is good to be out of shape big energy-absorbing effect, and back segment intensity ratio leading portion is little, has designed the energy-absorbing muscle of spacing alternation again, reach and be out of shape energy-absorbing step by step, deflection is relatively little when making the back segment distortion, and not even distortion is out of shape the energy-absorbing that diminishes gradually and is weakened in whole collision process, so not only played good energy-absorbing effect and also reduced the destruction of causing, improved the vehicle body safety because of collision.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Referring to Fig. 1, back collision longeron is welded to each other for two sections by front and back and forms.Longitudinal beam front section 1 is that structure strengthens the district, and expecting thick is 1.8mm, and longeron back segment 2 is energy-absorbing district step by step, and expecting thick is 1mm, is horizontally arranged with reinforced rib 3 on the beam of longeron back segment 2, and the spacing between reinforced rib reduces after by forward direction gradually.
Claims (2)
1, car collides girder work behind the energy-absorbing step by step, is distributed with reinforced rib on longeron, it is characterized in that longeron is divided into two sections of front and back, is welded to each other to form; Longitudinal beam front section is that structure is strengthened the district, and the longeron back segment is energy-absorbing district step by step, and the longitudinal beam front section material is thick in the longeron back segment, is horizontally arranged with reinforced rib on the beam of longeron back segment, and the spacing between reinforced rib reduces after by forward direction gradually.
2, car according to claim 1 collides girder work behind the energy-absorbing step by step, it is characterized in that: the longeron back segment for 1.8mm, the material of longitudinal beam front section is thick to be 1mm.
