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 adjustable gap assembled expansion block structure, which is suitable for use when the distance between the mounting hole position of the body sheet metal and the expansion block is long. Background Technology

[0002] In automotive body design, due to limited options for the mounting hole positions of expansion plugs on the body sheet metal, and sometimes using sheet metal from other models to save costs, the gap between the body and the expansion plug mounting points is often large. For installing expansion plugs over such long distances, the current common method is to create two different mounting holes on the body sheet metal: one circular (using a circular mounting clip) and the other oblong (using a circular clip, which can move laterally along the long side within the oblong hole to absorb tolerances). If the body sheet metal only has two circular holes, the two circular mounting clips may not be able to be installed into the mounting holes simultaneously, causing the expansion plug to fail to install. Furthermore, because the mounting hole positions on the body sheet metal are fixed, if a standard expansion plug is used, the distance between the two mounting points is fixed and cannot be adjusted. The large tolerances between the sheet metal and the plug also mean that the two mounting clips may not be able to be installed into the mounting holes simultaneously, resulting in the expansion plug failing to install. In this case, since the gap between the mounting holes of the two rubber blocks is large and the shape of the mounting holes is fixed as two round holes, it is not possible to rely on a single elongated hole to absorb the tolerance. Therefore, a new type of expansion block structure is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable-gap, modular expansion block structure, which solves the problem in existing technologies where the expansion block cannot be installed due to tolerances in the vehicle body sheet metal and the expansion block itself. It also allows the same expansion block to be used at locations with different sheet metal lengths (for vehicles on the same platform, using a portion of the sheet metal), thereby reducing costs.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: The adjustable gap assembly expansion block structure has four gap adjustment pins 6 on the left end of the first block 1 and four corresponding gap adjustment grooves 5 on the right end of the second block 2. The length of the gap adjustment grooves 5 is greater than the length of the gap adjustment pins 6. The four gap adjustment pins 6 are located in the four gap adjustment grooves 5 and can move laterally left and right. The first block 1 is assembled with the second block 2 as one unit through the gap adjustment grooves 5 and the gap adjustment pins 6, and then installed on the body sheet metal through the first buckle 3 and the second buckle 4.

[0005] There is a sufficient gap between the first adhesive block 1 and the second adhesive block 2 as a gap adjustment area 7. The first adhesive block 1 and the second adhesive block 2 can move laterally left and right through the gap adjustment groove 5 and the gap adjustment clip 6 to absorb sheet metal tolerances and adhesive block tolerances. The first adhesive block 1 and the second adhesive block 2 are assembled, which is simple to install and saves price and time costs.

[0006] The first plastic block 1 and the second plastic block 2 are respectively processed by injection molding, which has low mold cost and high production efficiency.

[0007] The advantages of this utility model are: novel design, simple structure, simple assembly method, and easy installation, saving both price and time costs. The rubber block is manufactured using injection molding, resulting in low mold costs and high production efficiency. The first and second rubber blocks can move laterally to accommodate sheet metal tolerances and rubber block tolerances. The same rubber block can also be used to install on two different sheet metal lengths (for vehicles on the same platform, borrowing part of the sheet metal) to reduce costs. It is highly practical.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. To make the above-mentioned objects, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] See Figures 1 to 10 As shown, the adjustable gap assembled expansion block structure of this utility model includes a first block 1, a second block 2, a first buckle 3, a second buckle 4, a gap adjustment groove 5, and gap adjustment pins 6. Four gap adjustment pins 6 are provided on the left end of the first block 1, and four corresponding gap adjustment grooves 5 are provided on the right end of the second block 2. The length of the gap adjustment groove 5 is greater than the length of the gap adjustment pins 6. The four gap adjustment pins 6 are located in the four gap adjustment grooves 5 and can move laterally left and right. The first block 1 is assembled with the second block 2 as a whole through the gap adjustment grooves 5 and the gap adjustment pins 6, and then installed on the body sheet metal through the first buckle 3 and the second buckle 4.

[0013] There is a sufficient gap between the first adhesive block 1 and the second adhesive block 2 as a gap adjustment area 7. The first adhesive block 1 and the second adhesive block 2 can move laterally left and right to absorb sheet metal tolerances and adhesive block tolerances. The first adhesive block 1 and the second adhesive block 2 are assembled, which is simple to install. This saves on price and time costs.

[0014] The first plastic block 1 and the second plastic block 2 are respectively processed by injection molding, which has low mold cost and high production efficiency.

[0015] See Figure 5 and Figure 6 As shown, when the gap between the first buckle 3 and the second buckle 4 is 325.28mm, the gap between the first rubber block 1 and the second rubber block 2 is adjusted to 13.5mm. Figure 6 This is the installation state onto the sheet metal. (The dimensions 325.28mm and 13.5mm in the example can be adjusted according to the actual sheet metal opening position).

[0016] See Figure 7 and Figure 8 As shown, when the gap between the first buckle 3 and the second buckle 4 is 333.28mm, the gap between the first rubber block 1 and the second rubber block 2 is adjusted to 21.5mm. Figure 8 This is the installation state onto the sheet metal. (The dimensions 325.28mm and 13.5mm in the example can be adjusted according to the actual sheet metal opening position).

[0017] See Figure 9 As shown, the lengths of design A and B (gap adjustment groove and gap adjustment clip) can be adjusted according to the sheet metal gap. The gap adjustment range of the rubber block is AB, in mm.

[0018] See Figure 10 As shown below, taking A=13 and B=5 as an example, the adjustment range for the gap between the rubber blocks is 13-5=8mm. (Dimensions AB in the figure can be adjusted according to the actual sheet metal data).

[0019] The adjustment range of the gap adjustment area 7 shown in the example is 8mm (the size of 8mm in the figure can be adjusted according to the actual sheet metal data) to avoid the problem of the glue block not being able to be installed due to tolerance.
