Description
Technical Field
[0001] The utility model relates to the technical field of automotive parts, and particularly to a general integrated structure for realizing the sealing of the sill aluminum beam. Background Art
[0002] Due to the continuous improvement of people's requirements for automotive performance, automotive noise reduction technology has received more extensive attention, and at the same time, there are higher requirements for the wading performance of automobiles. In order to improve this part of the relevant performance of the whole vehicle, sound absorption and insulation structures are often added to the sill aluminum beam of the vehicle body to seal the connection between cavities and achieve functional improvement. Most traditional sill aluminum beam seals use injection molded parts, greatly increasing the overall vehicle cost and mold cost. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is that most traditional automotive sill aluminum beam seals use injection molded parts, greatly increasing the overall vehicle cost and mold cost.
[0004] To solve the above problems, the technical solution of the utility model is: a general integrated structure for realizing the sealing of the sill aluminum beam, including a general skeleton, a metal clamping part, and an expansion component;
[0005] Two platform structures are symmetrically arranged at one end of the general skeleton, the expansion component is installed on the platform structure, and a through groove adapted to the metal clamping part is arranged in the middle of the general skeleton;
[0006] The expansion component includes a self-expanding sealing gasket and a buckle, and a through hole adapted to the buckle is arranged on the self-expanding sealing gasket.
[0007] Further, the general skeleton includes two U-shaped skeletons, and the two skeletons are connected and fixed by a cross bar, and the platform structure is located at the open end of the skeleton.
[0008] Further, the general skeleton is installed on the sill aluminum beam through the metal clamping part.
[0009] Further, an installation hole adapted to the buckle is arranged on the platform structure, and the self-expanding sealing gasket is installed on the platform structure through the buckle.
[0010] The advantages of the utility model compared with the existing technology are as follows: the utility model installs the expansion component on the general skeleton, and then installs the general skeleton on the sill aluminum beam through the metal clamping part, thus completing the sealing of the internal cavity of the sill aluminum beam. The shape of the self-expanding sealing gasket in the expansion component can be specifically selected according to the different shapes of the internal cavities of the sill aluminum beam. Compared with the traditional injection molded part seal, this general integrated structure not only reduces the production cost but also shortens the production cycle. Description of the Drawings

[0013] As shown in the figure: 1. Universal skeleton; 2. Metal clamping part; 3. Expansion component; 4. Threshold aluminum beam. Specific implementation manner
[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0015] As Figures 1 to 2 shown, a universal integrated structure for realizing the plugging of the threshold aluminum beam includes a universal skeleton 1, a metal clamping part 3 and an expansion component 2.
[0016] Two platform structures are symmetrically arranged at one end of the universal skeleton 1, the expansion component 2 is installed on the platform structure, a through groove adapted to the metal clamping part 3 is provided in the middle of the universal skeleton 1, the universal skeleton 1 includes two U-shaped skeletons, and the two skeletons are connected and fixed by a cross bar. The platform structure is located at the open end of the skeleton, and the universal skeleton 1 is installed on the threshold aluminum beam 4 through the metal clamping part 3.
[0017] The expansion component includes a self-expanding sealing gasket and a buckle. A through hole adapted to the buckle is provided on the self-expanding sealing gasket, and a mounting hole adapted to the buckle is provided on the platform structure. The self-expanding sealing gasket is installed on the platform structure through the buckle.
[0018] In specific use, the self-expanding sealing gasket in the expansion component 2 is installed on the universal skeleton 1 through the buckle, and then the universal skeleton 1 is installed on the threshold aluminum beam 4 through the metal clamping part 3, that is, the plugging of the internal cavity of the threshold aluminum beam 4 is completed. The shape of the self-expanding sealing gasket in the expansion component 2 can be specifically selected according to the different shapes of the internal cavity of the threshold aluminum beam 4.
[0019] To meet the NVH requirements and wading requirements of the threshold aluminum beam, traditional layout schemes all choose injection-molded expansion rubber blocks to plug the aluminum beam cavity. This requires an injection mold, with high production costs and a long cycle. By using this universal integrated structure, only a suitable expansion component 2 needs to be selected according to the different shapes of the internal cavity of the threshold aluminum beam 4, which not only reduces the production cost but also shortens the production cycle.
