[0030] In one embodiment, refer to Figures 1 to 7 This application provides an adjustable aircraft cockpit eye position positioning device. The device includes a C-shaped component 3 and a fixing assembly disposed at the front of the C-shaped component 3. The fixing assembly is connected to the central column of the sunroof frame and is connected to the front of the C-shaped component 3 through a first oblong hole 4, which is arranged laterally at the front of the C-shaped component 3. The top of the C-shaped component 3 is provided with two second oblong holes 6 and a round hole. The round hole is disposed on the outer side of the top of the C-shaped component 3, and the second oblong holes 6 are disposed on the inner side of the top of the C-shaped component 3. The bottom of the C-shaped component 3 is provided with two second oblong holes 6 and a round hole corresponding to the top of the C-shaped component 3. The two holes are located on the same plane. A second oblong hole 6 and a round hole are located at the three vertices of the triangle, respectively. The second oblong hole 6 is arranged laterally at the top and bottom of the C-shaped part 3. A first long screw is provided in the round hole that is arranged opposite to the top of the bottom of the C-shaped part 3. A second long screw is provided in the second oblong hole 6 that is arranged opposite to the top of the bottom of the C-shaped part 3. A first small ball that can move along the axis of the first long screw is sleeved in the middle area of the first long screw. A second small ball that can move along the axis of the second long screw is sleeved in the middle area of the second long screw. The size of the second small ball is larger than the size of the first small ball. The first small ball is threadedly connected to the first long screw, and the second small ball is threadedly connected to the second long screw.
[0031] In practice, small balls of different colors and sizes are used. The first small ball is set as a green ball 10, and the second small ball includes a first white ball 11 and a second white ball 12. Using the basic principle that three points can form a line, the driver can adjust the seat heading and height. When the green ball 10 coincides with the first white ball 11, or the green ball 10 coincides with the second white ball 12, the driver's left and right eye positions are positioned.
[0032] For example, one green ball 10 has a diameter of 14mm, and two white balls have a diameter of 16mm. Since the diameter of the green ball 10 is smaller than that of the white ball, when the observer's eye position, the green ball 10, and the white ball form a straight line within a viewing distance of 500-750mm, the observation result is that the green ball 10 occludes the white ball, and the overall outer contour of the white ball at the back can be clearly observed. This indicates that the designed eye position adjustment has reached the theoretical design value.
[0033] Furthermore, the fixing component is configured as two L-shaped profiles 1 facing back to back, with the bottom of the L-shaped profile 1 connected to the front end face of the C-shaped part through the first waist-shaped hole 4, and the opening of the L-shaped profile 1 facing outward.
[0034] In practical implementation, four 20mm long first oblong holes 4 are set on the front end face of the C-shaped part 3, which are connected to the L-shaped part 1 by four bolts 5. The L-shaped part 1 can be adjusted according to the windshield frame structure and thickness to meet the installation of sunroof frames with a thickness of 30-80mm. It is suitable for the cockpits of various existing small, medium, large, and heavy two-person pilot military and civilian transport aircraft and helicopters, and has the characteristics of strong versatility and "ready to use after installation". Each of the two L-shaped parts 1 is provided with two mounting holes 2, which can be used to connect the L-shaped part 1 to the central column of the sunroof frame by four screws. Its advantage is that it does not require a pre-set mounting groove on the central column of the sunroof frame for direct installation.
[0035] Two second oblong holes 6 are provided on the front of the upper and lower ends of the C-shaped part 3. Long screws 7 are connected and fixed to the C-shaped part 3 via nuts 8 and washers 9 on both sides. Each of the two long screws 7 has a small white metal ball (second ball) with a diameter of 16mm. A round hole is provided on the rear of the upper and lower ends of the C-shaped part 3 for installing one long screw 7. The long screw 7 is connected and fixed to the C-shaped part 3 via nuts 8 and washers 9 on both sides. A small green metal ball (first ball) with a diameter of 14mm is provided on the long screw 7. The three long screws 7 are threaded, and the three balls can be precisely adjusted in the aircraft altitude direction as needed. This allows for adaptation to cockpits with different eye-view heights. Simultaneously, the three metal balls form an isosceles triangle in space, with the apex angle adjustable within the range of 75° to 102°. Based on the specific parameters of the cockpit eye position design, and according to the reference marks marked on the C-shaped part 3, adjust the specific position of the long bolt 5 in the two second oblong holes 6 at the front of the C-shaped part 3, change the distance between the two long screws 7, realize the angle change of the isosceles triangle, meet the installation and use requirements of eye positions with different parameters, and have the advantages of strong versatility and high practicality.
[0036] In one embodiment, the length of the waist-shaped hole is 15mm-20mm.
[0037] In one embodiment, the spacing between the two second long screws is 34mm-68mm.
[0038] In one embodiment, the first ball is positioned at the center of the first screw to achieve an adjustment range of -17.5mm to 17.5mm along the aircraft altitude direction.
[0039] In one embodiment, the diameter of the first ball is 10mm-18mm.
[0040] In one embodiment, the diameter of the second ball is 12mm-20mm.
[0041] In one embodiment, the fixing component is adapted to the installation of the central column of a sunroof frame with a thickness of 30mm-80mm.
[0042] In one embodiment, the second oblong hole 6 is provided with equidistant scale markings 13 along its length. The second oblong hole 6 on the upper and lower end faces of the C-shaped part 3 is provided with equidistant scale markings, which can be adjusted according to the specific parameters of the designed eye position, adapting to cockpits of different geometric sizes, and has good expandability and convenience.
