Description

Clamping structure of automotive interior parts

technical field

The utility model relates to an automobile interior decoration, in particular to a connecting part when the automobile interior decoration is assembled.

Background technique

The use of automobiles is becoming more and more popular. In order to create a more comfortable, safe and individual car space, people have been pursuing high-grade, high-quality, and pollution-free automotive interiors. Therefore, automotive interior decoration products mostly adopt composite material injection molding to meet various interior decoration requirements such as soft decoration and fiberization, and the assembly requirements of automobile interior decoration are also getting higher and higher to meet the precision and reliability.

At present, in the assembly process of injection molded parts, the traditional integrated clamping structure of injection molded parts has the characteristics of simple mold structure and single function. In the case of overturning, there is a lack of design, which causes the appearance of the product to be poor after assembly, and it is easy to break when it is disassembled. The traditional solution needs to add parts and other structures, so that the number of molds is large, the mold structure is complicated, and the cost is high.

Utility model content

The purpose of the utility model is to provide a clamping structure of automobile interior parts with compact structure, reliability and low cost.

The technical solution for realizing the purpose of this utility model is as follows: a clamping structure of an automobile interior decoration, which has a clamping joint integrally formed with the main body part and a clamping interface arranged on the assembly part. The above-mentioned clamping joint is a double-piece structure, one of which is The clamping piece is provided with a clamping claw that cooperates with the card interface, and the other clamping piece is provided with a limit portion for cooperating with the card interface, and a "V"-shaped support bridge is provided between the two clamping pieces. The front ends of the above two clamping pieces are provided with installation guide surfaces, and the rear ends of the clamping pieces are provided with reinforcing ribs close to the main parts. The "V"-shaped opening of the above-mentioned "V"-shaped support bridge faces the main body part.

The advantages of this new type are compact structure, reliable installation, convenient disassembly, easy manufacture, and low cost; the "V"-shaped support bridge is arranged between the two clamping pieces, which effectively supports the elastic force of the clamping pieces and facilitates clamping assembly The clamping claw and the limiting part can prevent the main part from turning over and slipping through the cooperation with the clamping interface; the installation guide surface on the clamping piece makes full use of the elastic characteristics of plastics, so that the main part and the assembly part can be smoothly engaged.

detailed description

See Fig. 1 and Fig. 2, the clamping structure of the new automobile interior trim has a clamping joint formed integrally with the main part 7 and a clamping interface arranged on the assembly part 1. The above-mentioned clamping joint is a double-piece structure, and one of the clamping joints A snap-in claw 2 for cooperating with the card interface is provided on the connecting piece, a limit portion 3 for cooperating with the card interface is provided on the other snap-in piece, and a “V”-shaped support bridge 4 is provided between the two snap-in pieces. The front ends of the above two clips are provided with installation guide surfaces 6, and the rear ends of the clips are provided with reinforcing ribs 5 close to the main parts. The "V"-shaped opening of the above-mentioned "V"-shaped support bridge 4 faces the main body part 7 .

See Figure 3 and Figure 4, the new model uses PP+EPDM-TD20 as material, and is integrally formed by injection molding process. The snap-in claw 2 of the snap-in structure fits with the snap-in interface on the assembly part 1 in a clearance fit, the limit part 3 on one of the snap-in pieces of the snap-in joint fits with the snap-in interface without clearance, and the thickness of the "V"-shaped support bridge 4 is 1mm , the thickness of the ribs 5 between the clamping pieces is 1mm, the angle between the mounting guide surface 6 of the clamping structure and the loading direction is 30°, and the thickness of the clamping interface on the above-mentioned assembly parts is 2mm.

Apparently, the above specific implementation manners of the present utility model are only examples for clearly illustrating the present utility model, rather than limiting the implementation manner of the present utility model. Those of ordinary skill in the art can easily make other changes or substitutions on the basis of the above description, and these changes or substitutions will also be included in the protection scope of the utility model.
