Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing technology. Specifically, this utility model relates to a general-purpose expansion block. Background Technology

[0002] Currently, in the automotive manufacturing industry, the design of body expansion pads is primarily based on the specific shape of the body sheet metal. Existing body expansion pads are typically made of ordinary rubber or materials with a low foaming ratio, and their structure and shape perfectly conform to the corresponding body sheet metal parts. In practical applications, due to the differences in body structures between different car models, and even the different sheet metal shapes in different locations within the same car model, the expansion pads used for each car model and each location require specialized design and manufacturing.

[0003] Chinese patent (publication number: CN207466802U) discloses a foam bracket and a foam product. The foam bracket includes a bracket body, a connecting post extending from one side of the bracket body near its edge, and a spring sheet fixed to the bracket body via the connecting post; the spring sheet is parallel to the bracket body and protrudes from the side of the bracket body. However, the foam bracket and foam product require specialized design and manufacturing, and cannot be adapted to multiple vehicle models. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a universal expanding rubber block that can be used in various car models. To achieve the above objective, the technical solution adopted by this utility model is as follows: a universal expanding rubber block, including a mounting frame, one end of which is provided with a buckle, and a first expanding rubber and a second expanding rubber are provided on the mounting frame.

[0005] The mounting frame includes a base plate, one side of which is provided with a first limiting plate and a second limiting plate, and the other side of which is provided with a third limiting plate and a fourth limiting plate. The first foam adhesive is disposed between the first limiting plate and the second limiting plate, and the second foam adhesive is disposed between the third limiting plate and the fourth limiting plate.

[0006] The third limiting plate is provided with a first clamping plate, and the fourth limiting plate is provided with a second clamping plate.

[0007] The buckle includes a fixing plate, and a locking plate is symmetrically arranged at one end of the fixing plate.

[0008] Both the first limiting plate and the second limiting plate are triangular structures.

[0009] The first foam is an EVA foam injection molded integral structure, and the second foam is an EVA foam injection molded integral structure.

[0010] The base plate, the first limiting plate, the second limiting plate, the third limiting plate, the fourth limiting plate, the first clamping plate, and the second clamping plate are integrally formed.

[0011] The technical advantages of this invention are as follows: the first and second limiting plates precisely restrict the diffusion of the first foam adhesive in other directions, allowing it to better fill irregular gaps inside the vehicle body, thus enhancing the sealing effect. The second foam adhesive is positioned between the third and fourth limiting plates, which limit and fix it. When the second foam adhesive expands, it accurately fills the cavity space at the other end. Through the combined action of the first and second foam adhesives, comprehensive sealing and shock absorption are achieved for cavities of different shapes and sizes, improving the versatility and applicability of the adhesive block.

[0014] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0015] like Figure 1 As shown, a universal expanding rubber block includes a mounting frame 1, with a clip 2 at one end. A first expanding foam 3 and a second expanding foam 4 are disposed on the mounting frame 1. The mounting frame 1 is the main body of the universal expanding rubber block, and the clip 2 is the mounting base for the universal expanding rubber block, connecting to the mounting holes on the vehicle body sheet metal. After the universal expanding rubber block is fixed, it facilitates the directional foaming of the first expanding foam 3 and the second expanding foam 4, enhancing the strength of the sheet metal area in the universal expanding rubber block region.

[0016] The mounting frame 1 includes a base plate 101. One side of the base plate 101 is provided with a first limiting plate 102 and a second limiting plate 103, and the other side of the base plate 101 is provided with a third limiting plate 104 and a fourth limiting plate 105. A first expanding foam 3 is disposed between the first limiting plate 102 and the second limiting plate 103, and a second expanding foam 4 is disposed between the third limiting plate 104 and the fourth limiting plate 105. The base plate 101 is the main body for mounting the frame 1. A first limiting plate 102 and a second limiting plate 103 are spaced apart on one side of the base plate 101. A first expanding foam 3 is positioned between the first limiting plate 102 and the second limiting plate 103. The first and second limiting plates 102 and 103 precisely restrict the expansion of the first expanding foam 3 in other directions, allowing it to better fill irregular gaps inside the vehicle body, thus enhancing the sealing effect. A second expanding foam 4 is positioned between the third limiting plate 104 and the fourth limiting plate 105, which limit and fix the second expanding foam 4. When the second expanding foam 4 expands, it accurately fills the cavity space at the other end. Through the synergistic effect of the first expanding foam 3 and the second expanding foam 4, all-around sealing and shock absorption of the cavity are achieved, improving the versatility and applicability of the foam blocks.

[0017] The third limiting plate 104 is provided with a first clamping plate 5, and the fourth limiting plate 105 is provided with a second clamping plate 6. The first clamping plate 5 and the second clamping plate 6 can limit and guide the second expanding foam 4. When the second expanding foam 4 expands, the first clamping plate 5 and the second clamping plate 6 can precisely control the expansion direction and range of the expanding foam, so that the second expanding foam 4 accurately fills the corresponding cavity space, thereby improving the strength of the cavity area of ​​the general-purpose expanding foam block.

[0018] The clip 2 includes a fixing plate 201, with a symmetrically arranged clamping plate 202 at one end of the fixing plate 201. The fixing plate 201 is the main body of the clip 2. After the clamping plate 202 enters the mounting hole on the body sheet metal, the clamping plate 202 will abut against the mounting hole on the body sheet metal, fixing the entire universal expanding rubber block so that the first foaming adhesive 3 and the second foaming adhesive 4 can foam, thereby improving the universality and applicability of the entire universal expanding rubber block.

[0019] Both the first limiting plate 102 and the second limiting plate 103 are triangular in structure. The triangular structure increases the contact area between the first limiting plate 102 and the second limiting plate 103 and the first expanding foam 3, increasing the friction and bonding force between them. This effectively prevents the first expanding foam 3 from detaching from the first limiting plate 102 and the second limiting plate 103 during expansion, ensuring the durability of the sealing performance. The first limiting plate 102 and the second limiting plate 103 can also be configured with other structures, such as elliptical or square structures, to prevent the first expanding foam 3 from detaching from the first limiting plate 102 and the second limiting plate 103 during expansion and ensure that the foaming direction of the first expanding foam 3 is acceptable.

[0020] The first foam 3 and the second foam 4 are both EVA foam injection molded as a single unit. The fact that both foam 3 and foam 4 are EVA foam injection molded as a single unit results in higher foaming rates. When subjected to high-temperature environments such as automotive painting baking or other stimulating conditions, foam 3 and foam 4 decompose to generate a large amount of gas and begin to expand rapidly. The expanded foam 3 and foam 4 effectively block external noise, dust, and rainwater from entering the vehicle body, while also absorbing some vibration energy, reducing the impact of vehicle body vibration on ride comfort.

[0021] The base plate 101, the first limiting plate 102, the second limiting plate 103, the third limiting plate 104, the fourth limiting plate 105, the first clamping plate 5, and the second clamping plate 6 are integrally formed. This integrally formed structure results in higher connection strength and greater structural stability for the base plate 101, the first limiting plate 102, the second limiting plate 103, the third limiting plate 104, the fourth limiting plate 105, the first clamping plate 5, and the second clamping plate 6.

[0022] The role and effect of the embodiments

[0023] The first limiting plate 102 and the second limiting plate 103 precisely restrict the diffusion of the first expanding foam 3 in other directions. The first expanding foam 3 can better fill irregular gaps inside the vehicle body, thereby enhancing the sealing effect. The second expanding foam 4 is positioned between the third limiting plate 104 and the fourth limiting plate 105, which limit and fix the second expanding foam 4. When the second expanding foam 4 expands, it accurately fills the cavity space at the other end. Through the combined action of the first expanding foam 3 and the second expanding foam 4, all-round sealing and shock absorption of the cavity are achieved, improving the versatility and applicability of the foam block.

[0024] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
