[0002] A sunshade is a device used to prevent sunlight from irritating the pilot's eyes. Common aircraft cockpit sunshades are dark, non-metallic flat panels installed on the upper part of the cockpit windshield. When in use, they are flipped down to block the sunlight.

[0003] The existing sunshade device has a fixed position of the sun visor, which occupies the cockpit driving operation space and affects the overall interior effect of the cockpit. It cannot adjust the blocking angle according to the light angle, and the sunshade effect is limited, which affects the overall interior effect of the cockpit.

[0004] After searching, the Chinese patent with announcement number CN214824047U discloses an aircraft cockpit sunshade device. This utility model can adjust the angle between the sun visor and the adjustment rod according to the change of light angle by setting an auxiliary component. It has a good sunshade effect, and is set parallel to the adjustment rod when not in use, reducing the occupied space.

[0005] However, when the above-mentioned sunshade device is actually used, the aircraft itself will vibrate to a certain extent during takeoff and landing. After the sunshade device is opened, the sun visor cannot be positioned in time at different angles, which will cause the sun visor to deflect and reduce the sunshade effect of the sunshade device.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The embodiments of this application disclose Figure 1-7 The shown aircraft cockpit sunshade device comprises an outer shell 1, a fixed rod 2 is fixedly connected to the inside of the outer shell 1, and a rotation locking mechanism is provided on the outside of the fixed rod 2; the rotation locking mechanism comprises two blocks 3, the bottom of the block 3 is fixedly connected to the outside of the fixed rod 2, the inside of the fixed rod 2 is rotatably connected to two latches 4, the bottom of the latches 4 is fixedly connected to two springs 5, the bottom of the spring 5 is fixedly connected to a limiting ring 6, the bottom of the limiting ring 6 is fixedly connected to the upper surface of the fixed rod 2, the bottom of the fixed rod 2 is fixedly connected to an insertion rod 7, the inside of the insertion rod 7 is fixedly connected to a spring 2 8, the bottom end of the spring 2 8 is fixedly connected to a block 19, the outside of the block 19 is slidably connected to the inside of the insertion rod 7, the outside of the fixed rod 2 is slidably connected to a rotating drum 10, the outside of the rotating drum 10 is fixedly connected to two latches 11, slots 12 are provided at both ends of the rotating drum 10, and the two slots 12 are symmetrically arranged on the outside of the rotating drum 10. 2, a limiting groove 13 is provided on the inner side of the 2, and ratchets 14 are sleeved on both ends of the fixed rod 2. The inner side of the ratchet 14 is meshed with the latch teeth 4. Both sides of the ratchet 14 are fixedly connected to a swivel 15, and the inner side of the swivel 15 is rotatably connected to the outer side of the fixed rod 2; an extension mechanism is provided at the bottom of the shell 1, which pushes the rotating drum 10 toward the two sides of the fixed rod 2, so that the latching rod 11 on one side of the rotating drum 10 can better mesh with the outer side of the corresponding ratchet 14, so that the latching rod 11 on the other side of the rotating drum 10 is separated and meshed with the corresponding ratchet 14. Through the opposite arrangement of the latching grooves on the inner sides of the two ratchets 14 and the two latching teeth 4, the two latching teeth 4 and the ratchet 14 respectively limit the upward and downward rotation of the rotating drum 10, so that the device can rotate up and down freely, and after the latching rods 11 on both sides of the rotating drum 10 are in contact and meshed with the two ratchets 14, the rotating drum 10 will stop rotating, completing the locking of the rotation of the rotating drum 10.

[0027] Reference Figure 5 and Figure 6 As shown, the extension mechanism includes a connecting shell 16, the upper surface of the connecting shell 16 is fixedly connected to the bottom of the rotating drum 10, and a gear 17 is rotatably connected inside the connecting shell 16. Two baffles 18 are engaged on the outside of the gear 17, and the outer side of the baffle 18 is slidably connected to the inner side of the connecting shell 16. A plurality of limiting grooves 19 are provided on the outer side of one baffle 18. By pulling the baffle 18 on one side through the meshing transmission of the gear 17, the two baffles 18 can be moved from the inside of the connecting shell 16 to both sides at the same time, thereby increasing the sunshade area of ​​the baffle 18.

[0028] Reference Figure 5 and Figure 7 As shown, a fixed block 20 is fixedly connected to one side of the connecting shell 16, and a spring three 21 is fixedly connected to the inside of the fixed block 20. One end of the spring three 21 is fixedly connected to a clamping block 22. The outer side of the clamping block 22 is slidably connected to the inner side of the fixed block 20. A connecting rod 23 is fixedly connected to one side of the clamping block 22. The inner side of the connecting rod 23 is rotatably connected to a turntable 24. The spring three 21 pushes the clamping block 22 to limit the limiting groove 2 19 on the outer side of the baffle 18, so that the baffle 18 can be fixed after extension. Pulling the turntable 24 drives the connecting rod 23 and the clamping block 22 to move toward the inner side of the fixed block 20, and then rotates the turntable 24 so that the planes at the upper and lower ends of the turntable 24 can support the outer side of the fixed block 20, so that the clamping block 22 can always remain inside the fixed block 20, which is convenient for extending the baffle 18.

[0029] The working principle of the utility model is as follows: when the sun shines on the cockpit during the flight of the aircraft, the driver first pushes the two baffles 18 to drive the connecting shell 16 and the rotating drum 10 to slide on the outside of the fixed rod 2. After the slot 12 on one side of the rotating drum 10 is plugged into the insertion rod 7 on the outside of the fixed rod 2, the rotating drum 10 is continued to be pushed to one side so that the spring 2 8 and the card block 19 inside the insertion rod 7 can be clamped to the limiting groove 13 on the inside of the slot 12. After the spring 2 8 is clamped to the deepest limiting groove 13 on the inside of the slot 12, the card rod 11 on the top of the rotating drum 10 on the plugging side of the insertion rod 7 and the slot 12 is fully engaged with the outer side of the corresponding ratchet 14. At the same time, the card rod 11 on the other side will separate from the corresponding ratchet 14. Then, the baffle 18 and the rotating drum are rotated on the outside of the fixed rod 2. The cylinder 10 is assisted by the ratchet 10 when the baffle 18 is rotated in the opposite direction, and the ratchet 10 is assisted by the ratchet 10 when the baffle 18 is rotated in the opposite direction. After that, when the sunshade angle of the baffle 18 is determined, the cylinder 10 is moved toward the outer middle part of the fixed rod 2, so that the levers 11 on both sides of the cylinder 10 limit the two ratchets 14 evenly, so that the cylinder 10 can be fixed at the adjusted angle;

[0030] During the flight facing the sunlight, the turntable 24 is first rotated so that one end of the turntable 24 is engaged with the outer side of the fixed block 20. Then, during the rotation of the turntable 24, the connecting rod 23 and the block 22 are pulled to slide inside the fixed block 20. At the same time, without rotating the turntable 24, the block 22 will stay inside the fixed block 20. First, the baffle 18 on one side is pulled so that the baffle 18 on the other side can be transmitted through the gear 17 inside the connecting shell 16, so that the two baffles 18 can slide to both sides along the inner side of the connecting shell 16. Then, when the extension distance of the two baffles 18 is appropriate, the turntable 24 is rotated again so that the two block 22 are re-engaged with the limit groove 2 19 on the outer side of the baffle 18 under the push of the connecting rod 23, so that the two baffles 18 are stretched to increase a larger sunshade area.
