[0019] Example 1

[0020] like Figure 1 As shown, this detachable transparent component for a low-altitude aircraft includes a transparent component 100, a sealing strip 200, and a fuselage 300. The sealing strip 200 is located between the transparent component 100 and the fuselage 300 and serves as a sealing element for installation between them. The sealing strip 200 also improves the fit between the transparent component 100 and the fuselage 300 and enhances the appearance. For ease of installation, a detachable connection structure is provided between the transparent component 100 and the fuselage 300. The transparent component 100 is connected to the fuselage 300 via this detachable connection structure. This detachable connection structure replaces the adhesive-applied structure, simplifying installation, reducing stress, significantly lowering production time and costs, and improving production efficiency and yield. Specifically, in this embodiment, the detachable connection structure between the transparent component 100 and the fuselage 300 is a screw... In this embodiment, the transparent component 100 includes a body 400 made of PC material. For easy installation, a copper sleeve 500 is embedded in the body 400. The middle of the copper sleeve 500 is a fixing hole that passes through the body 400, the sealing strip 200, and the body 300. The detachable connection structure consists of 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 component 100 is formed by two-color injection molding, where the first color is PC101 and the second color is PUR102. A PUR medium is formed by two-color injection molding on the outer surface of the body 400. The PUR medium can improve the toughness and heat resistance of the transparent component 100. At the same time, the connection between the bolt 600 and the nut 700 replaces the glue structure, making installation simple and stress-free.

[0021] Example 2

[0022] like Figure 2As shown, most of the structure of this embodiment is the same as that of embodiment 1. The main difference is that the transparent part 100 is formed by three-color injection molding. The transparent part 100 includes a body 400. The first color of the transparent part 100 is PC101, the second color is PUR102, and the third color is PC / ABS103. The outer surface of the body 400 is injection molded with PUR medium formed by the second color. The PC / ABS103 has a through hole. The detachable connection structure is a bolt 600 and a nut 700. The bolt 600 passes through the through hole and one end is connected and fixed to the nut 700. The installation is achieved through the through hole on the PC / ABS103, which can reduce the stress on the body 400 and the risk of silver lines. Finally, putty and paint are applied to the bolt 600 to meet the appearance requirements.
