The sealing strip 200 is located between the transparent part 100 and the fuselage 300 and is used for installation and sealing between the transparent part 100 and the fuselage 300. The sealing strip 200 also improves the matching clearance and appearance effect between the transparent part 100 and the fuselage 300. Here, in order to facilitate installation, a detachable connecting structure is provided between the transparent part 100 and the fuselage 300. The transparent part 100 is connected and installed with the fuselage 300 through the detachable connecting structure. The detachable connecting structure is used here instead of the gluing structure, which is simple to install and has low stress, greatly reduces the production time cost, and improves the production efficiency and qualified rate of the product. Specifically, in this embodiment, the detachable connecting structure between the transparent part 100 and the fuselage 300 is a screw Bolt connection. In this embodiment, the transparent part 100 includes a main body 400, which is made of PC material. In order to facilitate installation, a copper sleeve 500 is embedded in the main body 400. The middle of the copper sleeve 500 is a fixing hole. The fixing hole passes through the main body 400, the sealing strip 200 and the fuselage 300 at the same time. The detachable connection structure is a bolt 600 and a nut 700. The bolt 600 passes through the fixing hole and one end is connected and fixed to the nut 700. The transparent part 100 is formed by two-color injection molding, wherein the first color is PC101 and the second color is PUR102. A PUR medium body is formed by two-color injection molding on the outer surface of the main body 400. Here, the PUR medium body can be used to improve the toughness and heat resistance of the transparent part 100. At the same time, the bolt 600 and the nut 700 are connected instead of the gluing structure, which is simple to install and has low stress.
[0021] Example 2
[0022] like Figure 2As shown, most of the structures of this embodiment are the same as those of Example 1, with the main difference being that the transparent member 100 is formed by three-color injection molding, and the transparent member 100 includes a body 400, the first color of the transparent member 100 is PC101, the second color is PUR102, and the third color is PC / ABS103, and a PUR medium body formed by the second color is injection-molded on the outer surface of the body 400, wherein the PC / ABS103 has a through hole, and the detachable connection structure is a bolt 600 and a nut 700, wherein the bolt 600 passes through the through hole and one end is connected and fixed to the nut 700, and the installation is achieved through the through hole on the PC / ABS103, which can reduce the stress of the body 400 and the risk of silver streaks; finally, putty is scraped and painted at the bolt 600 to meet the appearance requirements.
[0023] Example 3
[0024] The transparent part 100 is formed by three-color injection molding. The transparent part 100 includes a main body 400, wherein the first color of the transparent part 100 is PC101, the second color is PUR102, and the third color is PC / ABS103.
