Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile parts, in particular to an adhesive block for an automobile inner top. Background Art
[0002] With the rapid development of the automobile industry, people have increasingly stringent requirements for the comfort and noise control of automobiles, and the noise level inside the car has become one of the important indicators for judging riding comfort. However, with the increasing quality of my country's roads, especially the increasing number of expressways, cars are also moving towards high speed and light weight, and the resulting noise problem inside the car is becoming more and more prominent. On the other hand, with the improvement of people's living standards, cars have entered families in large numbers, people are exposed to more and more types of vehicles, their understanding of cars is constantly improving, and they are becoming more and more picky about the noise control inside the car.
[0003] In addition, it is well known that the interior parts of the car can play a very important role in controlling the noise inside the car. Therefore, the car is equipped with felt interior, which can absorb the noise inside the car on the one hand, and hide the car wiring and the roof steel structure on the other hand. The existing connection methods of car interiors mainly include gluing and snap connections. Among them, gluing is easily affected by the high temperature on the top of the car, which is easy to melt and affect the bonding effect, and it is easy to fall off; and the snap connection needs to be plugged into the car sheet metal, so the layout position is limited, especially for the position where the car sunroof is not suitable for setting the snap, and it is inconvenient to disassemble. Summary of the invention
[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides an adhesive block for an inner roof of an automobile, which has a simple structure, high connection reliability and is easy to disassemble.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A bonding block for an inner roof of an automobile is characterized in that it comprises an integrally injection-molded connection block body, one side of the connection block body has a boss, a plurality of hook groups are regularly arranged on the boss, each of the hook groups comprises two hooks arranged in a staggered manner, and the two hooks are bent and extended in opposite directions, both ends of the boss have hanging platforms, the top surfaces of both ends of the hanging platform along the width direction have first inclined surfaces, and both ends of the end surface of the hanging platform have second inclined surfaces.
[0007] Furthermore, the hook has a width that gradually decreases from the base to the tip.
[0008] Furthermore, the bottom surface of the boss has a plurality of material reduction grooves.
[0009] The beneficial effects of the utility model include: simple structure, convenient installation, good connection stability, little influence by temperature, and convenient assembly and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural schematic diagram of the utility model;
[0011] Figure 2 yes Figure 1 A partial enlarged view of
[0012] Figure 3 yes Figure 1 Schematic diagram of the back structure. DETAILED DESCRIPTION
[0013] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.
[0014] A kind of Figure 1-3 The adhesive block for the interior roof of the automobile shown is used for the installation and connection of the interior decoration of the automobile roof, especially for the connection of the interior decoration of the sunroof frame. Its structure includes a connection block body 1 that is integrally injection-molded, and one side of the connection block body 1 has a boss 2. A plurality of hook groups 3 are regularly arranged on the boss 2. Each hook group 3 includes two hooks 7 arranged in an interlaced manner, and the two hooks 7 are bent and extended in opposite directions. The interlaced hooks are used to connect with the felt block on the roof, that is, multiple limit connections are formed with the fibers on the felt through multiple hooks. There are hanging platforms 4 at both ends of the boss 2, which are used to limit the connection in the embedded groove on the interior decoration of the automobile sunroof. The top surfaces of the two ends of the hanging platform 4 along the width direction have a first inclined surface 5, and the two ends of the end surface of the hanging platform 4 have a second inclined surface 6. This structure is convenient for inserting into the embedded groove during installation. If the structures at both ends are the same, it can be installed regardless of the front or back, thereby improving the installation efficiency.
[0015] In order to improve the structural stability of a single hook 7, the utility model is designed that the width of the hook 7 gradually decreases from the root to the tip. This structure can prevent the hook from being broken, and the tip of the hook 7 is easy to insert into the fiber layer or deform and be taken out of the fiber layer during installation and disassembly.
[0016] In order to save material, the bottom surface of the boss 2 of this embodiment has a plurality of material reduction grooves 8 .
[0017] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present invention.
