[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] In the figure, there are a carbon fiber skeleton 100, a connecting bracket 200, a mounting buckle 300, a surface layer 400, a mounting bracket 500, a fuselage 600, a rivet hole 700, a blind rivet 800, a rivet sealing layer 900, and an adhesive layer 1000.

[0023] like Figure 1 As shown, the carbon fiber composite material product installation and 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. The carbon fiber composite material is not limited to carbon fiber, for example but not limited to glass fiber, etc. Here, the entire installation and connection structure includes a carbon fiber skeleton 100, 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.

[0024] There is a connection matching structure between the connecting bracket 200 and the carbon fiber skeleton 100, and the connecting bracket 200 is installed and connected to the carbon fiber skeleton 100 through the connection matching structure. The mounting buckle 300 is connected and installed on the connecting bracket 200 and is installed and connected to the opponent through the mounting buckle 300. In this embodiment, the opponent has a fuselage 600 of a flying car as an example. There is a mounting bracket 500 between the mounting buckle 300 and the opponent. The upper part of the mounting buckle 300 is installed and connected to the connecting bracket 200, and the lower part is installed and connected to the mounting bracket 500. There is a connection between the mounting bracket 500 and the opponent. The carbon fiber skeleton 100 is connected to the same connecting and matching structure, so that the non-formable part is designed as an independent mounting bracket 500, and the entire carbon fiber composite material product is connected to the body by riveting and bonding, 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. For different installation parts, different structures can be used during connection and installation. There are mainly two types of connecting and matching structures in this patent, one is a riveting connection structure, and the other is a bonding structure. For the fuselage 600 of the flying car, bonding can be used in the middle position, and in order to increase the strength, riveting is used at the edge.

[0025] Specifically, if Figure 2 as well as Figure 3 As shown, when the connecting matching structure is a blind rivet 800 and a rivet hole 700 opened between the carbon fiber skeleton 100 and the connecting bracket 200, the blind rivet 800 passes through the rivet hole 700 to rivet the carbon fiber skeleton 100 and the connecting bracket 200 together. Here, the connecting bracket 200 is made of PC, ABS or stainless steel material, and the mounting buckle 300 is a separate part or is 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, a rivet sealing layer 900 is provided on the upper end surface of the rivet hole 700 after riveting. Here, the rivet sealing layer 900 can be formed by glue pouring. 00 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 the glue is poured. Similarly, the connection matching structure of the connection part between the other end and the fuselage 600 is a blind rivet 800 and a rivet hole 700 opened between the opponent and the mounting bracket 500. The mounting bracket 500 can be made of PC, ABS or metal material. In this embodiment, the mounting bracket 500 is a metal bracket. The blind rivet 800 passes through the rivet hole 700 to rivet the opponent and the mounting bracket 500 together. Similarly, the rivet hole 700 is sealed by glue pouring, so that the entire carbon fiber composite material product can be installed on the fuselage 600 of the flying car. Figure 4 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 700 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 clip 300 is installed on the connecting bracket 200. Similarly, the rivet holes 700 between the hand piece 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 clip 300 is installed into the mounting bracket 500.

[0026] like Figure 5 as well as Figure 6As shown, the connection and matching structure between the mounting bracket 500 and the opponent part is an adhesive layer 1000 arranged between the opponent part and the mounting bracket 500, and the adhesive layer 1000 can be bonded with structural adhesive. The mounting bracket 500 is installed and connected to the opponent part through the adhesive layer 1000. Here, the connecting bracket 200 is made of PC, ABS or stainless steel material, and the mounting buckle 300 is a separate part or is 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, and the connection and matching structure between the mounting bracket 500 at the other end and the opponent part is an adhesive layer 1000 arranged between the opponent part and the mounting bracket 500. The mounting bracket 500 is installed and connected to the opponent part through the adhesive layer 1000. The mounting bracket 500 can be made of PC, ABS or metal material. In this embodiment, the mounting bracket 500 is a metal bracket. After the mounting buckle 300 is connected to the connecting bracket 200, the other end is installed on the mounting bracket 500, so that the entire carbon fiber composite material product can be installed on the fuselage 600 of the flying car.

[0027] The specific embodiments described in this article are merely examples of the spirit of the present invention. Technicians in the technical field to which the present invention belongs can make various modifications to the described specific embodiments or replace them in similar ways, but they will not deviate from the scope defined by the spirit of the present invention.
