Description

Technical Field

[0001] This utility model relates to the field of automotive body sheet metal sound insulation parts manufacturing, and in particular to an expansion rubber block structure for partial assembly of different sheet metals. Background Technology

[0002] To reduce production costs and increase profits, OEMs have adopted platform-based design in recent years, resulting in some body panels having similar structures or being completely reused. When two expansion blocks need to be designed for different locations on the same model, or two expansion blocks need to be designed for the same location on different models, some parts of the body panel structure are completely identical, while others are different. Generally, two different shapes of expansion blocks are designed based on the two body panel shapes. These two expansion blocks require two sets of large-sized molds, leading to high costs and high unit prices, resulting in unnecessary resource waste and urgently needing improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a universal expansion block structure for partial assembly of different sheet metal parts. This solves the problems of high mold costs, high unit prices, and resource waste caused by the need to design two different shapes of expansion blocks when two body parts share the same sheet metal or have different sheet metal parts. This invention uses an assembly method, sharing a portion of the expansion blocks, reducing the volume of expansion blocks for different body sheet metal parts, thus saving on expansion block usage costs for OEMs using similar sheet metal for models on the same platform.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: The expansion block structure for partial assembly of different sheet metals includes a common expansion block 2, an expansion block 1, and an expansion block 3. The expansion block 1 and the expansion block 3 are each designed with two mounting pins 6 of the same size, and the ends of the mounting pins 6 are provided with anti-loosening protrusions 8. The common expansion block 2 is designed with four mounting holes 7 that cooperate with the mounting pins 6.

[0005] The adhesive block 1 is connected to the common adhesive block 2 via mounting nails 6 and mounting holes 7 to form a combined adhesive block 4.

[0006] The adhesive block 3 is connected to the common adhesive block 2 via mounting nails 6 and mounting holes 7 to form a combined adhesive block 2 5.

[0007] The anti-detachment protrusion 8 has a height of 3mm and a thickness of 1.5mm.

[0008] The diameter of the mounting hole 7 is 4mm, and the diameter of the mounting pin 6 is 3mm.

[0009] The advantages of this invention are: novel design, simple structure, and convenient use. By using an assembly and connection structure, two different shaped rubber blocks can be installed onto another rubber block, avoiding the need to design two different large-sized rubber blocks and significantly reducing the cost of using rubber blocks. It is highly practical. Attached Figure Description
