Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
A side wall reinforcing frame comprises a body 10 which is integrally annular, and the body 10 of an integrated structure is formed by butt welding and connecting plate edges of strip plate-shaped plate bodies. Therefore, the plate bodies of the body 10 are not overlapped, the dead weight of the side wall reinforcing frame can be obviously reduced, and meanwhile, the plate bodies are connected into a whole, so that the body 10 has higher structural strength, and the reliability is greatly improved.
Preferably, the butt weld of the body 10 is composed of vertical welds 11a and transverse welds 11b, each of the vertical welds 11a being arranged parallel to each other and each of the transverse welds 11b being arranged parallel to each other. Two types of welding seams which are arranged vertically and horizontally can realize the reliable connection of the plate bodies and form the annular body 10. The butt welding seams arranged in parallel are processed by adopting two welding guns, so that the angle of the welding guns does not need to be adjusted, the welding cost can be further reduced, and the processing efficiency is improved. It should be noted that the vertical weld 11a and the transverse weld 11b are used to indicate that there are two types of welds and an included angle between the two types of welds in the body 10.
Preferably, the body 10 comprises an A-pillar reinforcing plate 12 and a B-pillar reinforcing plate 13 which are vertically arranged integrally, the A-pillar reinforcing plate 12 and the B-pillar reinforcing plate 13 are in transitional connection above an AB-pillar connecting plate 14 and below a threshold reinforcing plate 15, and the AB-pillar connecting plate 14 and the threshold reinforcing plate 15 are transversely arranged integrally.
In this embodiment, the middle plate of the AB column connecting plate 14 extends downward to form a convex portion, and the convex portion is connected with the upper plate of the B column reinforcing plate 13 by butt welding, and the butt welding seam is a transverse welding seam 11B, and the middle plate of the threshold reinforcing plate 15 extends upward to form a convex portion, and the convex portion is connected with the lower plate of the B column reinforcing plate 13 by butt welding, and the butt welding seam is a transverse welding seam 11B. The A-pillar reinforcing plate 12 comprises an A-pillar upper reinforcing plate 121 and an A-pillar lower reinforcing plate 122, the rear end plate edge of the A-pillar upper reinforcing plate 121 is in butt welding connection with the front end plate edge of the AB-pillar connecting plate 14, the butt welding seam is a vertical welding seam 11a, the front end of the A-pillar upper reinforcing plate 121 extends downwards to form a convex portion and the upper plate edge of the A-pillar lower reinforcing plate 122 in butt welding connection, the butt welding seam is a transverse welding seam 11b, and the lower plate body of the A-pillar lower reinforcing plate 122 extends backwards to form a convex portion and the front end plate edge of the sill reinforcing plate 15 in butt welding connection, and the butt welding seam is a vertical welding seam 11a. The connecting weld of each plate body is parallel to each other or perpendicular, namely vertical weld 11a and horizontal weld 11b mutually perpendicular, wherein, vertical weld 11a plummet is arranged, and horizontal weld 11b horizontal arrangement and horizontal weld 11b accord with the longitudinal direction of automobile body, and the connecting weld of each plate body is arranged with the transmission direction of power is perpendicular like this, can further promote the reliability of connecting weld to promote the structural strength and the reliability performance of body 10.
In specific implementation, the plate bodies of the body 10 are connected into an integral annular plate by using a laser tailor welding technology. In order to ensure the connection quality of the body 10, the plate bodies are made of the same material, and in order to reduce the dead weight of the body 10 while ensuring the strength requirement of the body 10, the thickness of each plate body can be different.
Because the plate body of the body 10 is arranged reasonably, the body 10 can meet the strength requirement by adopting a material with smaller material thickness.
In the conventional technique shown in fig. 1, the plates a1, a3 and a5 are cold-stamped materials, the plates a2 and a4 are hot-formed materials, and the plate thickness of the plate a1 is t1The plate thickness of the plate a2 is t2The plate thickness of the plate a3 is t3The plate thickness of the plate a4 is t4The plate thickness of the plate a5 is t5。
In the embodiment shown in fig. 2, each plate body is made of a thermo-forming material, and the plate thickness of the reinforcement plate 121 on the a-pillar is t1The plate thickness of the A-pillar lower reinforcing plate 122 is t2The thickness of the doorsill reinforcing plate 15 is less than t3The thickness of the B-pillar reinforcement plate 13 is t4The thickness of the AB column connecting plate 14 is less than t4。
In other words, in the embodiment, each plate body of the main body 10 is made of the same material, which is convenient for material management and processing, and reduces the production cost. Meanwhile, on the premise of meeting the strength requirement, the body 10 eliminates the overlapping area of the plate body, reduces the plate thickness of the reinforcing plate at the doorsill and the reinforcing plate at the A, B column joint, further reduces the dead weight of the body 10 and ensures the realization of light weight of the automobile body.
