Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a plastic blocking structure applied to aluminum profiles. Background Art

[0002] In the structural design of automobiles, aluminum profiles are widely used in body frames, chassis and other key parts. When aluminum profiles are used as automobile parts, they can not only significantly reduce the overall weight of the vehicle and improve fuel efficiency, but also provide good impact resistance and structural rigidity, thereby improving driving safety.

[0003] The aluminum profiles used in automobiles have open cavities. When in use, aluminum plugging sheets are usually used to block the ports of the above cavities to prevent external air from entering the cab through sheet metal positioning holes, weight reduction holes, mounting holes (without sealing pads), etc., thereby preventing noise from entering the car through the medium of air. The use of aluminum plugging sheets for blocking in the prior art has the following shortcomings:

[0004] First, aluminum plugging pieces are mostly formed by hot extrusion process. For complex aluminum profile structures, they need to be bent to the shape of the corresponding plugging pieces, which increases the processing difficulty of the aluminum plugging pieces. In addition, aluminum plugging pieces also have the disadvantage of high material cost.

[0005] Second, since aluminum plugging pieces are difficult to process and are not easy to match with corresponding mechanical connection structures (common mechanical connection structures (bolts, screws, rivets and other mechanical fasteners) require additional connection positions to be processed on the aluminum plugging pieces), aluminum plugging pieces are mostly connected by welding, which results in low installation efficiency.

[0006] Third, the aluminum plugging piece is prone to surface oxidation when it encounters corrosion, which shortens the service life and has the disadvantage of a low service life. Utility Model Content
