Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber products, and specifically relates to a glue riveting connection structure of a carbon fiber (not limited to carbon fiber, composite materials must include, for example but not limited to glass fiber, etc.) product. Background Art

[0002] Carbon fiber (not limited to carbon fiber, composite materials are also required to be included, such as but not limited to glass fiber, etc.) products are often needed as interior decoration (not just interior decoration, most parts are used) on the interior of vertical lift (not just vertical lift aircraft, other aircraft must also be included, not only used on aircraft, such as cars, etc.). Since carbon fiber products (composite materials) are all produced by molding (not just molding, they are mainly divided into thermoplastic and thermosetting, but no matter what process, the installation structure cannot be molded in the mold) process, it is impossible to mold the installation structure like plastic injection molding integration. Currently, it is common to install it directly on other products through glue. The disadvantage of this is that it cannot be disassembled and maintained, and the bonding tooling is too large, the cost is high, and the adjustable space is small. In particular, high strength needs to be guaranteed at the edge position. Ordinary bonding cannot meet the strength requirements (there is no problem with the strength of the glue, the main consideration is disassembly and maintenance, and the bonding tooling is too large, the cost is high, and the adjustable space is small). Therefore, the connection structure needs to be improved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a glue riveting connection structure of carbon fiber products which is convenient to install, has good strength and can solve the problems of small adjustable space and the like, in view of the current status of the prior art.

[0005] In the above-mentioned glue-riveted connection structure of a carbon fiber product, the carbon fiber skeleton and the connecting bracket are opened and aligned to form rivet holes, and the rivet holes form a sealing step portion at the carbon fiber skeleton, and the aperture of the sealing step portion is larger than the aperture of the rivet hole at the connecting bracket.

[0006] In the above-mentioned glue-riveted connection structure of a carbon fiber product, the sealing step portion has a rivet sealing layer, and the rivet sealing layer and the surface of the carbon fiber skeleton are kept flat.

[0007] In the above-mentioned glue-riveted connection structure of a carbon fiber product, the outer surface of the carbon fiber skeleton has a surface layer.

[0008] In the above-mentioned glue-riveted connection structure of a carbon fiber product, the carbon fiber frame is installed between the fuselage through a mounting clip, a mounting bracket is provided between the mounting clip and the fuselage, the upper part of the mounting clip is mounted and connected to the connecting bracket, and the lower part is mounted and connected to the mounting bracket.

[0018] like Figure 1As shown, the glue-riveted connection structure is mainly used to install the interior product made of the carbon fiber skeleton 100 on the fuselage 600 of the flying car. Here, carbon fiber is not limited to carbon fiber, and composite materials are also possible, such as but not limited to glass fiber, etc. Here, the glue-riveted connection structure includes a carbon fiber skeleton 100, a core-pulling rivet 800, a connecting bracket 200 and a mounting buckle 300. When there is a need for appearance, a surface layer 400 can be provided on the outer surface of the carbon fiber skeleton 100, wherein the surface layer 400 can be a suede coating, a paint layer, an ink layer or a PUR layer. The carbon fiber skeleton 100 is installed with the fuselage 600 through the mounting buckle 300, and a mounting bracket 500 is arranged between the mounting buckle 300 and the fuselage 600. The upper part of the mounting buckle 500 is installed and connected with the connecting bracket 200, and the lower part is installed and connected with the mounting bracket 500. The entire carbon fiber product is connected to the fuselage by riveting, which solves the problems of being unable to disassemble and install, the bonding tooling is too large, the cost is high, and the adjustable space is small, and a certain strength can be guaranteed at the same time.

[0019] Specifically, if Figure 2 as well as Figure 3 As shown, the carbon fiber skeleton 100 and the connecting bracket 200 are opened and aligned to form a rivet hole 700, and the rivet hole 700 forms a sealing step 1000 at the carbon fiber skeleton 100. The aperture of the sealing step 1000 is larger than the aperture of the rivet hole 700 at the connecting bracket 200. Here, the connecting bracket 200 is made of PC, ABS or stainless steel material, and the mounting buckle 300 is a separate part or integrally formed with the connecting bracket 200, which is convenient for disassembly and installation. In this embodiment, the connecting bracket 200 is a plastic bracket. In order to ensure good sealing performance After riveting, the sealing step portion 1000 has a rivet sealing layer 900, where the rivet sealing layer 900 can be formed by glue pouring, and the rivet sealing layer 900 and the surface of the carbon fiber skeleton 100 are kept flat. Here, the rivet sealing layer 900 is mainly polished to be flat after glue pouring, and the mounting bracket 500 and the fuselage 600 are opened and aligned to form a rivet hole 700, and the rivet hole 700 also forms a sealing step portion 1000 at the fuselage 600, and the aperture of the sealing step portion 1000 is larger than the aperture of the rivet hole 700 at the mounting bracket 500, such as Figure 3 As shown, when performing riveting connection, taking the carbon fiber skeleton 100 and the connecting bracket 200 as an example (the fuselage 600 is the same), first, rivet holes are opened on the carbon fiber skeleton 100 and the connecting bracket 200 and aligned, and then the blind rivets 800 are installed and riveted, and then the glue is poured and polished, and then the surface layer 400 is added, and then the buckle 300 is installed on the connecting bracket 200. Similarly, the rivet holes 700 between the fuselage 600 and the mounting bracket 500 are aligned, and then the blind rivets 800 are installed and riveted, and then the glue is poured, and the mounting buckle 300 is installed into the mounting bracket 500.
