Description

Technical Field

[0001] The invention relates to a method for installing and positioning an aircraft cabin decorative panel. Background Art

[0002] Aircraft cabins are places for passengers to rest, work and entertain. The main uses of aircraft cabin decorative panels are cabin decoration, ensuring cabin safety and reducing noise, providing passengers with a good environment and improving their experience.

[0003] The commonly used installation method of aircraft cabin decorative panels is as follows: use positioning pins to position, and then use mushroom buckles to fix. Among them, mushroom buckles are a quick and safe structure that can be opened and closed, which can replace nuts / bolts, buckles, pins, nails, zippers, welding, etc. For example, 3M mushroom buckles are composed of two plastic backing strips with mushroom-shaped plastic protrusions (mushroom heads) on the backing strips. There are different mesh numbers of mushroom heads per square inch, 170, 250, and 400 meshes. The higher the mesh number, the greater the closure strength. The back of the mushroom head can be selected with different adhesives or without adhesives as needed. When the two pieces of the mushroom buckle are pressed together, the mushroom heads will lock with each other and make a crackling sound. If necessary, they can be opened and can be reused 1000 times.

[0004] This assembly method requires that the locating pin and the locating pin support position match accurately. When the assembly accuracy is insufficient, the locating pin is often installed off-center, resulting in the decorative panel not being able to maintain verticality and horizontality, affecting the aesthetics of the cabin interior. Summary of the invention

[0005] The object of the present invention is to provide a method for installing and positioning an aircraft cabin decorative panel, aiming to achieve accurate and rapid positioning of the decorative panel after the initial installation and positioning, thereby improving the efficiency of disassembly and assembly.

[0006] The purpose of the present invention can be achieved through the following technical solutions.

[0007] A method for installing and positioning a decorative panel in an aircraft cabin, wherein a structural panel and a decorative panel in the aircraft cabin are connected via a mounting hole on the structural panel, a positioning pin support, a bracket, a positioning pin and a mushroom buckle, wherein the positioning pin support is mounted on the structural panel via a bracket, and the positioning pin is mounted on the decorative panel, the positioning pin support and the positioning pin are configured as a plug-in assembly that can be connected through the mounting hole, and the sub-buckle and the female buckle of the mushroom buckle are matched and arranged on the structural panel and the decorative panel;

[0008] The installation and positioning method comprises the following steps:

[0009] S1. After moving the decorative panel so that it matches the position of the structural panel, the decorative panel is temporarily fixed to the structural panel;

[0010] S2. Adjust the position of the locating pin support and the bracket on the structural plate, and mark the mounting point of the locating pin support and the bracket when the locating pin position matches the locating pin position;

[0011] S3. According to the marked installation points, the positioning pin support is installed on the bracket by fasteners, and the bracket is installed on the structural plate by fasteners, and the mounting surface where the positioning pin support is connected to the bracket is provided with an elongated or elliptical positioning pin support hole, and the mounting surface where the bracket is connected to the structural plate is provided with an elongated or elliptical bracket hole;

[0012] S4. Install the decorative panel in place;

[0013] S5. Disassemble the decorative panel, verify the installation effect of the positioning pin support and the positioning pin, and then reinstall the decorative panel.

[0014] The method of the present invention is used to install the decorative panel of the aircraft cabin. After the decorative panel is installed for the first time, the subsequent removal and installation can be more accurate and quick. The positioning pin support hole and the bracket hole are set to be elongated or elliptical. During the installation process, the position of the positioning pin support can be fine-tuned to match the position of the positioning pin, thereby ensuring the installation accuracy and ensuring that the decorative panel is always installed in the ideal position.

[0015] The present invention also has the following preferred design:

[0016] The cross section of the bracket of the present invention is "L"-shaped, one mounting surface of the bracket is used to connect with the structural plate, and the other mounting surface is used to connect with the positioning pin support.

[0017] The length direction of the positioning pin support hole of the present invention is perpendicular to the length direction of the bracket hole, so that the up-down and left-right positions of the positioning pin support can be fine-tuned.

[0018] The structural plate and the decorative plate of the present invention are connected by a plurality of strip-shaped mushroom buckles.

[0019] The structural plate and the decorative plate of the present invention are connected via a plug-in assembly consisting of a plurality of groups of positioning pin supports and positioning pins.

[0020] The present invention has the following beneficial effects:

[0021] The method of the present invention is used to install the decorative panel of the aircraft cabin. After the decorative panel is installed for the first time, the subsequent disassembly and reinstallation can be more accurate and quick. The positioning pin support hole and the bracket hole are set to be elongated or elliptical. During the installation process, the position of the positioning pin support can be fine-tuned to match the position of the positioning pin, thereby ensuring the installation accuracy and ensuring that the decorative panel is always installed in the ideal position.
