[0044] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] like Figures 1-6 As shown, the present invention provides a carbon ceramic hatch hinge mechanism, including a door frame bracket 100, a hatch bracket 200, and a moving component 300;

[0046] The door frame bracket 100 is provided with a sliding groove assembly 101;

[0047] The hatch support 200 is provided with a hatch slide groove 201; the hatch support 200 is also provided with a first rotating shaft 202;

[0048] The moving component 300 includes a first moving part 301 and a second moving part 302;

[0049] One end of the first moving part 301 is connected to the first rotating shaft 202, and the other end of the first moving part 301 is connected to the slide groove assembly 101;

[0050] One end of the second moving part 302 is connected to the hatch slide 201, and the other end of the second moving part 302 is connected to the slide assembly 101.

[0051] In one embodiment of the present invention, such as Figure 1-6As shown, the door frame bracket 100 is fixed to the door frame of the aircraft fuselage, and the cabin door bracket 200 is fixed to the aircraft cabin door. The door frame bracket 100 and the cabin door bracket 200 are connected and fixed through the movable component 300. The opening of the aircraft cabin door is also mainly carried out through the cooperation of the door frame bracket 100, the cabin door bracket 200 and the movable component 300 to ensure the normal operation of the aircraft.

[0052] The movable component 300 is movable on the door frame support 100 and the hatch support 200. The door frame support 100 is provided with a sliding groove assembly 101, and the hatch support 200 is provided with a hatch sliding groove 201. A first rotating shaft 202 is also fixed on the hatch support 200, and the first rotating shaft 202 is located at the upper end of the hatch sliding groove 201.

[0053] The movable component 300 includes two types of movable components: a first movable component 301 and a second movable component 302. The right end of the first movable component 301 is rotatably connected to a first rotating shaft 202 on the hatch support 200. The first rotating shaft 202 can rotate on the hatch support 200, but its position on the hatch support 200 is immovable. The left end of the first movable component 301 is slidably connected to the slide rail assembly 101 via a movable shaft. The right end of the first movable component 301 is fixed on the hatch support 200 and moves with the hatch support 200. The right end of the first movable component 301 not only moves with the door frame support 100 but can also move within the slide rail assembly 101 of the door frame support 100, increasing the range of movement and flexibility of the first movable component 301.

[0054] The right end of the second moving part 302 is slidably connected to the hatch slide groove 201 via a moving shaft, and the left end of the second moving part 302 is slidably connected to the slide groove assembly 101 via a moving shaft. Both ends of the second moving part 302 can move within the slide groove, thereby increasing the range of movement of the second moving part 302 and improving the flexibility of movement of the second moving part 302.

[0055] When the aircraft stops flying and the cabin door is opened, the cabin door support 200 moves with the cabin door, while the door frame support 100 remains stationary. The cabin door support 200 and the moving component 300 move along two straight grooves in the slide rail assembly 101 via the moving shaft and move to the end of the two straight grooves. At this time, the cabin door moves outward and opens, increasing the distance between the cabin door and the aircraft door frame. This is mainly to avoid interference between the cabin door and the door frame when the cabin door rotates. For cabin doors of different thicknesses, workers can design the length of the straight grooves in the slide rail assembly 101 according to the actual thickness of the cabin door, making it convenient for workers to open and close the cabin door and avoiding the phenomenon of the cabin door colliding with the door frame.

[0056] Then, as the hatch slides outward and opens, the distance between the hatch and the aircraft door frame increases. The moving component 300 slides in the arc-shaped groove in the slide rail assembly 101, opening the hatch at a certain initial angle. Finally, the second moving component 302 slides along the hatch slide rail 201, opening the hatch at another certain angle. The opening angle of the hatch is related to the length of the arc-shaped groove in the slide rail assembly 101 and the hatch slide rail 201. Workers can determine the length of the slide rail according to their needs, making it convenient to open hatches of different thicknesses and to open them at different angles. This is convenient, quick, and highly applicable.

[0057] Similarly, when the hatch is closed, the moving component 300 returns along the original path to safely close the hatch.

[0058] More preferably, the slide rail assembly 101 includes a first straight slide rail 102, a second straight slide rail 103, and a door frame arc groove 104; the second straight slide rail 103 is connected to the door frame arc groove 104.

[0059] In one embodiment of the present invention, such as Figure 2 , Figure 3 As shown, the slide rail assembly 101 includes a first straight slide rail 102, a second straight slide rail 103, and a door frame arc groove 104. The second straight slide rail 103 and the door frame arc groove 104 are an integral slide rail. The first moving member 301 and the second moving member 302 can directly slide along the second straight slide rail 103 onto the door frame arc groove 104 via the moving shaft.

[0060] When the aircraft stops flying and the cabin door is opened, the left end of the moving component 300 moves upward along the first linear slide 102 and the second linear slide 103, and the cabin door moves outward and opens, increasing the distance between the cabin door and the aircraft door frame. This is mainly to avoid interference between the cabin door and the door frame when the cabin door rotates. For cabin doors of different thicknesses, workers can design the length of the first linear slide 102 and the second linear slide 103 according to the actual thickness of the cabin door, so as to facilitate workers to open and close the cabin door and avoid the phenomenon of the cabin door colliding with the door frame.

[0061] Then, as the hatch slides outward and opens, the distance between the hatch and the aircraft door frame increases. The first moving part 301 and the second moving part 302 are no longer in the moving position within the first straight slide groove 102. The moving part 300 slides along the arc groove 104 of the door frame via the moving axis within the first straight slide groove 102, causing the hatch to open at a certain initial angle. Subsequently, the second moving part 302 slides along the hatch slide groove 201, causing the hatch to open again at a certain angle. The opening angle of the hatch is related to the length of the arc groove within the slide groove assembly 101 and the hatch slide groove 201. Workers can determine the length of the slide groove according to the hatch thickness requirements, which facilitates the opening of hatches of different thicknesses and allows for opening at different angles. This is convenient, quick, and highly applicable.

[0062] More preferably, the included angle between the second linear groove 103 and the door frame arc groove 104 is set to an obtuse angle.

[0063] In one embodiment of the present invention, such as Figure 2 , Figure 3 As shown, compared to acute or right angles, setting the included angle between the second straight slide groove 103 and the door frame arc groove 104 to an obtuse angle makes it easier for the moving component 300 to slide between the second straight slide groove 103 and the door frame arc groove 104, making it easier for the aircraft door to close and making the movement of the moving component 300 smoother.

[0064] More preferably, the hatch slide 201 is configured as an arc-shaped slide.

[0065] In one embodiment of the present invention, such as Figure 2 , Figure 3 As shown, the arc-shaped hatch slide 201 is fixed on the hatch, and the hatch moves along an arc-shaped line. The corresponding hatch slide 201 is also set to an arc-shaped structure as the hatch moves. The opening angle of the hatch depends on the length of the hatch slide 201 and the arc-shaped groove 104 of the door frame. Workers can set the length of the two arc-shaped slides according to actual needs.

[0066] More preferably, the first moving member 301 includes a first moving rod 303 and a first arc-shaped rod 304;

[0067] One end of the first moving rod 303 is connected to one end of the first arc-shaped rod 304;

[0068] The intersection of the first moving rod 303 and the first arc-shaped rod 304 is connected to the second straight slide groove 103; the other end of the first moving rod 303 is connected to the first straight slide groove 102; the other end of the first arc-shaped rod 304 is connected to the first rotating shaft 202.

[0069] In one embodiment of the present invention, such as Figure 2 , Figure 3 As shown, the first moving part 301 is an integral structure formed by the first moving rod 303 and the first arc-shaped rod 304. The first moving rod 303 is a straight rod, which facilitates its vertical movement in the first straight groove 102 and the second straight groove 103. The lower end of the first moving rod 303 is connected to the left end of the first arc-shaped rod 304. The two form a moving part with a U-shaped structure. The upper end of the first moving rod 303 slides in the first straight groove 102 through the moving shaft, so that the hatch is away from the door frame and avoids interference between the thickness of the hatch and the door frame.

[0070] The first moving rod 303 and the first arc-shaped rod 304 intersect and are slidably connected to the second straight slide groove 103 via a moving shaft, so that the hatch opens to a certain initial angle. The right end of the first arc-shaped rod 304 is rotatably connected to the first rotating shaft 202, so that the second moving part 302 can slide in the hatch slide groove 201 with the first rotating shaft 202 as the axis, so that the hatch opens to a certain angle again, making it convenient for workers to open the hatch.

[0071] More preferably, the second moving member 302 includes a second moving rod 305 and a second arc-shaped rod 306;

[0072] One end of the second moving rod 305 is connected to one end of the second arc-shaped rod 306;

[0073] The intersection of the second moving rod 305 and the second arc rod 306 is connected to the second straight slide groove 103; the other end of the second moving rod 305 is connected to the first straight slide groove 102; the other end of the second arc rod 306 is connected to the hatch slide groove 201.

[0074] In one embodiment of the present invention, such as Figure 2 , Figure 3 As shown, the second moving part 302 is an integral structure formed by combining the second moving rod 305 and the second arc-shaped rod 306. The second moving rod 305 is a straight rod, which facilitates its vertical movement within the first straight slide groove 102 and the second straight slide groove 103. The lower end of the second moving rod 305 is connected to the left end of the second arc-shaped rod 306, and the two form a U-shaped moving part. The upper end of the second moving rod 305 slides within the first straight slide groove 102 via a moving shaft, so that the hatch is away from the door frame, avoiding interference between the thickness of the hatch and the door frame.

[0075] The second moving rod 305 and the second arc rod 306 are connected at a position that moves within the second straight slide groove 103 via a moving shaft. The right end of the second arc rod 306 slides within the hatch slide groove 201 via a moving shaft, allowing the hatch to open at a certain angle again, making it easier for workers to open the hatch.

[0076] The first moving rod 303 and the second moving rod 305 have the same movement trajectory. The upper and lower ends of the two moving rods are respectively sleeved on the same moving shaft and slide within the door frame bracket 100.

[0077] More preferably, there are two second moving parts 302; the first moving part 301 is located between the two second moving parts 302.

[0078] In one embodiment of the present invention, such as Figure 2 , Figure 3As shown, the first moving part 301 is positioned between the two second moving parts 302, which can increase the stability of the moving assembly 300 and make the hatch opening and closing smoother.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
