The tabletop 1 is installed at one end of the hinge assembly 4 and is located between the horizontal page 45 and the vertical page 452. The horizontal page 45 and the vertical page 452 are perpendicularly connected. The hinge assembly 4 is installed back-to-back with the aircraft seat back, enabling the tabletop 1 to be unfolded and folded. The rotatable panel 6 is connected to the tabletop 1 via a seat body 5 and supports multi-angle rotation. The screw adjustment mechanism 2 is installed inside the tabletop 1, and the rotatable panel 6 is hinged to the screw adjustment mechanism 2. By rotating the handwheel 21, the screw adjustment mechanism 2 can be moved, causing the rotatable panel 6 to rotate around the seat body 5, thereby adjusting the angle of the rotatable panel 6 and allowing it to rotate flexibly along the seat body 5, greatly facilitating passenger use.

[0040] In this embodiment, the desktop board 1 serves as the basic support platform. Its surface can be integrated with an anti-slip and wear-resistant coating, and its edges are designed with rounded edges to effectively prevent bumps and improve safety during use.

[0041] Both the desktop panel 1 and the rotatable panel 6 are made of lightweight, high-strength materials (such as carbon fiber composite materials), which reduces weight while ensuring structural stability. The size and angle adjustment range of the desktop panel 1 and the rotatable panel 6 must strictly conform to ergonomic principles to improve passenger comfort.

[0042] Both the hinge assembly 4 and the lead screw adjustment mechanism 2 are made of corrosion-resistant metal materials (such as stainless steel), ensuring their durability and reliability.

[0043] like Figure 2 , Figure 3 and Figure 4As shown, the lead screw adjustment mechanism 2 includes a rotating shaft 211, a lead screw 22, a nut 23 mounted on the outer periphery of the lead screw 22, a sliding block 24 mounted on the nut 23, and a connecting rod 26. The rotating shaft 211 is connected to the side end of the desktop 1, and a handwheel 21 is fitted onto the outer periphery of the rotating shaft 211. The lead screw 22 is mounted together with a pair of bearing seats 221 located inside the desktop 1, and the rotating shaft 211 is connected to the end of the lead screw 22, thereby providing a stable transmission effect and reducing friction loss. One end of the connecting rod 26 is hinged to a first hinge seat 261 located on the sliding block 24, and the other end is hinged to a second hinge seat 262 located on the bottom surface of the rotatable panel 6. The angle adjustment of the rotatable panel 6 is achieved through the first hinge seat 261 and the second hinge seat 262.

[0044] In this embodiment, the rotating shaft 211 and the lead screw 22 are coaxially arranged, and the lead screw 22 is driven to rotate by rotating the handwheel 21. The sliding block 24 is slidably connected to the guide rod 25 disposed in the desktop 1, converting the rotational motion into linear motion, and the sliding block 24 slides along the guide rod 25. By rotating the handwheel 21, the rotating shaft 211 and the lead screw 22 are driven to rotate, thereby driving the nut 23 and the sliding block 24 to move linearly along the guide rod 25. The sliding block 24 pushes the rotatable panel 6 to rotate around the base 5 through the connecting rod 26, realizing angle adjustment.

[0045] like Figure 1 and Figure 7 As shown, a mounting block 31 is fixed to the side of the desktop panel 1. The mounting block 31 is provided with a fixing bolt 3, which is used to temporarily fix the desktop panel 1 to the seat frame for easy maintenance.

[0048] In this embodiment, a fixed frame 7 and a movable frame 8 are installed on the rotatable panel 6 for fixing items of different sizes (such as tablet computers, books, etc.). The first set screw 71 on the fixed frame 7 initially fixes the items, while the movable frame 8 achieves adaptive clamping through the slide groove 61 and the compression spring 62, and the second set screw 81 on the movable frame 8 can complete the fixing of the items.

[0049] like Figure 3 and Figure 6As shown, the fixed body 41 is connected to the seat back by the mounting screw 9, the rotating body 451 is linked with the tabletop 1, and a washer 91 is provided between the mounting screw 9 and the fixed body 41 to ensure a stable connection between the hinge assembly 4 and the seat back and reduce vibration.

[0050] The operation process is as follows:

[0051] 1. Unfolding the tabletop: The passenger pulls the tabletop 1, and the rotating body 451 of the hinge assembly 4 rotates relative to the fixed part 41. The end of the limiting platform 44 abuts against the fixed part 41, so that the tabletop 1 unfolds to a horizontal position.

[0052] 2. Adjust the panel angle: Rotate the handwheel 21 to adjust the angle of the rotatable panel 6 to the desired position via the screw adjustment mechanism 2.

[0053] 3. Secure the item: Place the item on the rotatable panel 6 and secure it using the first set screw 71 on the fixing bracket 7 and the second set screw 81 on the movable bracket 8.
