Description
Technical Field
The utility model belongs to the technical field of the car, especially, relate to a car side wall door ring structure.
Background
In the process of implementing the present invention, the inventor finds that the prior art has at least the following problems:
with the continuous development of economy, automobiles are more and more popularized, the problem of traffic safety is more and more concerned, automobile consumers take safety performance indexes as an important consideration for selecting automobiles, and the problem of automobile collision safety is more and more emphasized. The safety performance of the vehicle body framework is improved mainly by improving the strength of the vehicle body in the metal plate structure of the personnel cabin. According to the traditional reinforcing method, the sheet metal A column, the sheet metal B column and the threshold at the position of the personnel cabin are reinforced in material thickness and material and locally reinforced by the sheet metal joint. This conventional reinforcement method tends to result in increased vehicle body weight and cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an adopt the integral type to take shape is provided, has avoided connecting the car side wall door ring structure of position solder joint inefficacy problem
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: an automobile side wall door ring structure, comprising:
an A-pillar section including an A-pillar upper portion and an A-pillar lower portion;
the upper end of the column B and the upper part of the column A are of an integrated structure;
and the lower part of the A column is connected with the first end of the threshold part through laser tailor welding, and the upper part of the B column part is connected with the second end of the threshold part through laser tailor welding.
The thickness of the material of the threshold part is 1.2 mm.
The material thickness of the column A and the column B is 1.4 mm.
The A column portion, the B column portion and the threshold portion are made of hot forming steel plates.
One of the technical schemes has the following advantages or beneficial effects, and the joint is formed integrally, so that the failure of welding spots at the joint position is avoided.
Drawings
Fig. 1 is a schematic structural view of a side door ring structure of an automobile provided in an embodiment of the present invention;
FIG. 2 is a cross-sectional view A-A of FIG. 1;
the labels in the above figures are: 1. the upper part of the column A, the lower parts of the column A, the column B, the threshold part, the column A, the column B, the column A, the threshold part and the column B, and the laser splicing and welding line.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1-2, an automotive side door ring structure has:
an A-pillar section including an A-pillar upper portion and an A-pillar lower portion;
the upper end of the column B and the upper part of the column A are of an integrated structure;
and the lower part of the A column is connected with the first end of the threshold part through laser tailor welding, and the upper part of the B column part is connected with the second end of the threshold part through laser tailor welding. The side wall door ring threshold position and other positions are welded in a tailor-welded mode through laser, the material thickness is reduced by 0.2mm relative to other positions, and the side wall reinforced door ring is reduced into a door ring single piece through four parts of a traditional A column upper reinforcing plate, an A column lower reinforcing plate, a threshold reinforcing plate and a B column reinforcing plate.
The thickness of the material of the threshold part is 1.2 mm. The thicknesses of the material of the column A and the column B are 1.4 mm. The door ring thermoform material is defined as PHS 1500.
The A column part, the B column part and the threshold part are made of hot forming steel plates, and the forming process is hot forming.
The side wall door ring threshold position and other positions are welded in a tailor-welded mode through laser, the material thickness is reduced by 0.2mm relative to other positions, and the side wall reinforced door ring is reduced into a door ring single piece through four parts of a traditional A column upper reinforcing plate, an A column lower reinforcing plate, a threshold reinforcing plate and a B column reinforcing plate.
The collision performance of the automobile body framework can be improved, the number of automobile body parts is reduced, and the tooling cost of corresponding dies, clamps and checking tools is saved. The weight is reduced by about 3Kg compared with the traditional structure under the requirement of equivalent performance. The welding tolerance accumulation is reduced, and the dimensional precision is easier to control.
After the structure is adopted, the integrated forming is adopted, and the failure of welding spots at the joint part is avoided.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
