Abstract
The invention relates to a car door anti-collision beam. The car door anti-collision beam comprises a first plate and a second plate, which are arranged in parallel and are elongated. Two long edges of the first plate are bent towards the second plate respectively, two long edges of the second plate are bent towards the first plate respectively, and the long edges of the first plate and the corresponding long edges of the second plate are in butt joint and fixed. According to the car door anti-collision beam, the parallel first plate and second plate form a box structure, and the anti-collision beam is high in strength and is better than the anti-collision beam formed by direct stamping of metal plates; the anti-collision beam can be subjected to direct laser welding with the a car door inner plate instead of being fixed with the car door inner plate through connectors, the anti-collision beam and the car door inner plate welding strength is good, and the anti-collision beam is simple and convenient to mount.
Description
Technical field
The present invention relates to a kind of sedan door collision prevention girders.
Background technology
Collision prevention girders is the important protecting component on sedan door.Existing collision prevention girders has two kinds of versions, and one is to be formed by metal plate punching, and two ends and inner plate of car door are welded to connect, and its advantage is simple installation, and shortcoming is that self intensity difference, impact strength are poor; Another kind of version is pipe beam type collision prevention girders, this kind of structure is to be made by a hollow tubular, two ends respectively increase an attaching parts again and inner plate of car door is fixed, its advantage is that self intensity is higher, shortcoming is because be the assembly set that welds formation by two guarantors, so a little less than assembly rigidity, impact strength is poor, install complicated.
Summary of the invention
The object of the invention is to, for the deficiencies in the prior art, provide a kind of sedan door collision prevention girders, impact strength is high, simple installation.
Technical scheme of the present invention is, a kind of sedan door collision prevention girders, comprise the first plate body and the second plate body that are arranged in parallel, and the first plate body and the second plate body are strip, two long limits of the first plate body are respectively to the second plate body direction bending, and two long limits of the second plate body are also respectively to the first plate body direction bending, the long limit docking corresponding with the second plate body of the long limit of described the first plate body is fixing.
It is rectangular box-like that the present invention adopts two boards body to be spliced into, and between two boards body, except stitching portion, there is no overlapping place, simple in structure so on the one hand, is easy to processing and fabricating, and productive costs is low, is conducive to body lightening; On the other hand, self intensity is high, impact strength is high, when collision, has enough energy-absorbing buffering spaces, and anti-invasion is effective.One in two boards body can be used as inner panel and presses close to inner plate of car door, the two ends of overall collision prevention girders can be directly and inner plate of car door adopt laser welding, not only convenient but also firm.
The first plate body and the second plate body are made by the Heat forming of high strength steel sheet metal component, contact edges all between the first plate body and the second plate body are all fixed by laser welding, to reach the welding effect of laser full weld, although be assembly, but just the same with global formation part out, integral rigidity and intensity are all very good.Above structure not only production technology is simple, and the fastness connecting between two boards body is good.
On the plate face of described the first plate body, along plate body length direction, be provided with to the first plate body U-lag of the second plate body direction depression.
On the plate face of described the second plate body, along plate body length direction, be provided with to the second plate body U-lag of the first plate body direction depression.
U-lag can increase the structural strength of plate body, further to improve impact strength.
Preferably, described the first plate body U-lag is located at the middle part of the first plate body, and described the second plate body U-lag is located at the middle part of the second plate body.U-lag is located at plate body middle part, can farthest increase the structural strength of plate body.
The present invention, as a kind of sedan door collision prevention girders, forms box like structure by the first plate body being arranged in parallel and the second plate body, and self intensity is high, is better than the collision prevention girders that panel beating is directly stamped to form; Collision prevention girders can be directly and inner plate of car door laser welding, without fixing by attaching parts and inner plate of car door, good with inner plate of car door weld strength, simple installation; Collision prevention girders with together with edge-to-edge's laser full weld, without design welding flange, has reduced the use of material by the first plate body being arranged side by side and the second plate body, has alleviated the quality of part; The first plate body and second plate body structure of collision prevention girders are simple, are easy to processing and fabricating.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention;
Fig. 2 is part-structure lateral plan of the present invention;
Fig. 3 is A-A welded section figure in Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of sedan door collision prevention girders, comprise the first plate body 1 and the second plate body 2 that are arranged in parallel, and the first plate body 1 and the second plate body 2 are strip, two long limits of the first plate body 1 are respectively to the second plate body 2 direction bendings, and two long limits of the second plate body 2 are also respectively to the first plate body 1 direction bending, the long limit docking corresponding with the second plate body 2 of the long limit of described the first plate body 1 is fixing.
The plate face middle part of the first plate body 1 is provided with to the first plate body U-lag 3 of the second plate body 2 direction depressions along plate body length direction; The plate face middle part of the second plate body 2 is provided with to the second plate body U-lag 4 of the first plate body 1 direction depression along plate body length direction.
The docking fixed form on the first plate body 1 long limit corresponding to the second plate body 2 is welding, and weld seam 5 shapes as shown in Figure 3.
