Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile door frame upper strip structure. Background Art

[0002] As a key component of automobile door frames, the design and manufacturing technology of automobile door frame upper strips is crucial. Referring to the Chinese invention patent application (application publication number: CN107082008A), an improved structure of the cross-section of automobile door frame upper strips and its manufacturing method are disclosed. This innovation uses a piece of plate to form a complex structure including a hook part, an overlapping part, an outer side end of the vehicle and a cylindrical part through continuous roll forming. Among them, a support pocket is provided in the center of the cylindrical part, which is intended to increase the cross-sectional area of ​​the structure, thereby significantly improving the rigidity of the product. In the overlapping part where the hook extension part, the cylindrical starting end and the cylindrical extension fitting part meet, three layers of materials are superimposed. This area is precisely welded by laser along the length direction of the door frame to ensure that the components are firmly combined into a whole.

[0003] The highlight of this invention is that the addition of the support pocket not only expands the cross-sectional area and enhances the rigidity of the product, but also cleverly sets the laser welding point at the center of the overlapped part, effectively ensuring the tight connection between the hook extension part, the cylindrical starting end and the cylindrical extension fitting part. The application of laser welding significantly improves the overall welding strength and performance of the door frame upper strip. In addition, the shrinkage design of the cylindrical starting end also has an anti-corrosion function, which fully guarantees the quality of the product.

[0004] However, although the structure integrates rolling and laser welding to achieve a breakthrough in performance, its complex manufacturing process requires the rolling equipment to be bulky and have a precise structure, which to a certain extent increases the production cost of the automobile door frame upper strip.
