[0043] like Figures 1 to 6 As shown, an embodiment of the present application provides a helicopter full-view door, comprising:
[0044] like Figure 1 As shown, the cabin door body 1 includes a door panel 11 and a visual window 12. The visual window 12 is provided on the door panel 11. The visual window 12 is curved and bulges toward the outside of the helicopter cabin. The visual window 12 is composed of two transparent units 121. The two transparent units 121 are connected to form a complete visual window 12. The two transparent units 121 are rotatably connected to the door panel 11. The door panel 11 is provided with a door handle 111 and a door lock 112. The door lock 112 can firmly lock the cabin door body 1 to the aircraft cabin to improve safety. The door handle 111 can facilitate the opening and closing of the cabin door body 1.
[0045] In an embodiment of the present application, the transparent unit 121 is rotatably connected to the door panel 11 through a rotating shaft. The rotating shaft is embedded in the door panel 11, and a damping is provided at the rotating shaft. The rotation connection position is located on the opposite side of the two symmetrically arranged transparent units 121. The close ends of the two transparent units 121 abut against each other on the symmetry axis. On the door panel 11, an avoidance embedding groove is opened at the position of the rotating shaft, thereby ensuring that the transparent unit 121 can be opened to the outside of the cabin without obstacles.
[0046] like Figure 1、 Figure 2 、 Figure 3 and Figure 4 As shown, the limiting and fixing component 3 is slidably installed in the door panel 11, and an adjustment block 33 is fixed on the limiting and fixing component 3. The adjustment block 33 extends from the limiting and fixing component 3 toward the inside of the helicopter cockpit, and a sliding groove 114 is provided on the inner side of the door panel 11 for the adjustment block 33 to extend and slide.
[0047] like Figure 4 As shown, the driving component 4, the output end of the driving component 4 and the limiting and fixing component 3 are connected by a connecting rod 423, which is used to drive the limiting and fixing component 3 to approach the edge of the transparent unit 121 to limit the rotation of the transparent unit 121, or drive the limiting and fixing component 3 away from the transparent unit 121 to release the restriction on the transparent unit 121.
[0048] like Figure 5 and Figure 6 As shown, the demolition component 5 is used to destroy the connecting rod 423, and the adjustment block 33 is used to be manually operated to drive the limiting and fixing component 3 away from the transparent unit 121 to release the restriction on the transparent unit 121 after the connecting rod 423 is destroyed.
[0049] The visual window 12, which is composed of two transparent units 121, bulges to one side, allowing the personnel in the cabin to observe the external environment in full view when performing flight missions. The connecting splint 2 rotates the transparent unit 121 to the door panel 11, and the visual window 12 composed of the transparent units 121 can be opened outward by rotating it, which not only further increases the field of view, but also can be used for escape in the event of an accident. The limit fixing component 3 is used to fix the visual window 12 to the door panel 11. When the visual window 12 is not needed to be opened, it can ensure the safety of the personnel in the cabin during the flight and further reduce wind noise and temperature loss. The setting of the adjustment block 33 can manually directly release the fixed limit, so that after an accident occurs in the aircraft, the personnel in the cabin can open the visual window 12 more quickly and open the escape passage for emergency escape, effectively improving the emergency escape probability of the personnel in the cabin.
[0050] like Figure 2 and Figure 3 As shown, the helicopter full-view door also includes a connecting splint 2. The connecting splint 2 is made of metal material, and the connecting splint 2 is wrapped around the edge of the transparent unit 121, and a cavity is formed between the connecting splint 2 and the edge of the transparent unit 121; in the embodiment of the present application, the connecting splint 2 is made of stainless steel alloy, and the connecting splint 2 has the same edge contour shape as the transparent unit 121, and the connecting splint 2 is wrapped around the edge of the transparent unit 121 by bonding.
[0051] like Figures 2 to 4As shown, each of the two transparent units 121 is correspondingly provided with a limiting fixing component 3, and each of the two limiting fixing components 3 is correspondingly provided with an adjustment block 33 and a connecting rod 423. The limiting fixing component 3 includes a mounting bracket 31 and a limiting column 32. The mounting bracket 31 is slidably connected to the door panel 11, and the output end of the driving component 4 is connected to the mounting bracket 31 through a connecting rod 423. The edge shape of the mounting bracket 31 is the same as that of the transparent unit 121. The mounting bracket 31 is located at the outer periphery of the transparent unit 121. There are multiple limiting columns 32, and multiple limiting columns 32 are symmetrically fixed on the mounting bracket 31. The limiting columns 32 are installed on the side of the mounting bracket 31 facing the transparent unit 121. A limiting hole 21 is opened at the position corresponding to the connecting splint 2 and the limiting column 32. The limiting column 32 is used to extend into the limiting hole 21. A cavity is formed between the connecting splint 2 and the edge of the transparent unit 121 to provide space for accommodating the limiting column 32.
[0052] By moving the mounting bracket 31 through the driving component 4 or manually controlling the adjustment block 33, the limiting column 32 can be inserted into the limiting hole 21, so that the limiting column 32 is located in the cavity formed between the connecting splint 2 and the visual window 12 to limit and fix the visual window 12, thereby firmly limiting the visual window 12 on the door panel 11. When the mounting bracket 31 drives the limiting column 32 to move out of the limiting hole 21, the transparent unit 121 can be rotated by the rotating shaft embedded in the door panel 11.
[0053] Regarding the setting of the sliding groove 114 and the adjustment block 33: the sliding groove 114 perpendicular to the mating surfaces of the two transparent units 121 is opened on the side of the mounting frame 31 on the door panel 11 away from the transparent unit 121, and the adjustment block 33 is fixedly connected to the mounting frame 31.
[0054] In this embodiment, a sealing strip 6 is provided on the opposite side of the connecting plate 2 and the mounting bracket 31. The sealing strip 6 is bonded to one side of the mounting bracket 31. The sealing strip 6 prevents rapid temperature loss within the chamber, reduces wind noise, and reduces hard contact damage to the transparent unit caused by bumps.
[0055] like Figure 4 As shown, the driving assembly 4 includes:
[0056] A rotating handle 41 is rotatably connected to the door panel 11 . The rotating handle 41 is located on a side of the door panel 11 facing the interior of the cockpit.
[0057] The connecting rod driving member 42 is used to drive the movement of the limiting and fixing assembly 3 on one side.
[0058] The gear driving member 43 is used to drive the movement of the limiting and fixing component 3 on the other side.
[0059] The connecting rod driving member 42 and the gear driving member 43 are both driven by the rotating handle 41 .
[0060] After the handle 41 is rotated, the fixing rod 421 is driven to rotate, and the fixing rod 421 and the connecting rod 423 are rotatably connected, so that one end of the connecting rod 423 can be driven to rotate along the rotation connection point between the connecting rod 423 and the door panel 11 as the center of the circle, and then the other end of the rotating rod 422 is driven to rotate in the opposite direction, thereby driving the connecting rod 423 to move along the length direction parallel to the slide groove 114, and finally removing the limiting column 32 from the limiting hole 21, which has the advantages of easy operation and simple structure.
[0061] The connecting rod driving member 42 includes:
[0062] A fixing rod 421 is fixedly connected to the rotating handle 41 and is located inside the door panel 11 .
[0063] The rotating rod 422 has one end that is rotatably connected to the end of the fixed rod 421 , a point between the two ends of the rotating rod 422 is rotatably connected to the door panel 11 , and the other end of the rotating rod 422 is fixedly connected to the mounting bracket 31 through the connecting rod 423 .
[0064] Regarding the specific setting of the connecting rod: the cross-sectional area of the connecting rod 423 is smaller than the cross-sectional areas of the fixed rod 421 and the rotating rod 422, one end of the connecting rod 423 is rotatably connected to the end of the rotating rod 422, and the other end is fixedly connected to the adjustment block 33.
[0065] The gear drive member 43 includes a plurality of gears 431 and a rack 432. The number of the gears 431 is an even number. In this embodiment, there are four gears 431 and one rack 432. The rotating handle 41 is provided with gear teeth. The plurality of gears 431 are arranged adjacent to each other, and two adjacent gears 431 are meshed with each other. The gears 431 at both ends of the plurality of adjacently arranged gears 431 are respectively meshed with the rotating handle 41 and the rack 432. One end of the rack 432 is fixedly connected to the other mounting bracket 31 via the connecting rod 423.
[0066] The personnel in the cabin can simultaneously control the movement of the connecting rod driving member 42 and the gear driving member 43 by turning the handle 41. When the handle 41 is turned 90° clockwise, the fixed rod 421 rotates from the vertical direction to the horizontal direction. The fixed rod 421 can drive one end of the rotating rod 422 to make an arc motion with the rotating connection between the rotating rod 422 and the door panel 11 as the center, and then drive the other end of the rotating rod 422 to lift upward, thereby driving the connecting rod 423 to lift vertically upward, and then by lifting the mounting frame 31, the limiting column 32 located in the upper part is removed from the limiting hole 21; at the same time, the gear teeth on the rotating handle 41 will drive the gear 431 meshing with it to rotate, and through the sequential driving of the adjacent gears 431, the rack 432 can eventually be moved downward in the vertical direction, and the rack 432 will drive the connecting rod 423 connected to it to move downward, and finally the limiting column 32 located in the lower part is removed from the limiting hole 21, thereby releasing the limiting fixation of the viewing window 12.
[0067] As for the gear drive, in other embodiments, the gear drive may also include two driving gears and a belt, the driving gear including a large wheel and a small wheel, the large wheel and the small wheel are concentrically connected and integrally formed, the large wheel of one driving gear is engaged with the gear teeth of the rotating handle, and the large wheel of the other driving gear is engaged with the rack, the belt is sleeved on the small wheels of the two driving gears, and by turning the rotating handle, the rotating handle drives the large wheel engaged with it to rotate, thereby driving the small wheel to rotate, and the small wheel drives the belt to drive the small wheel of the other driving gear to rotate, and finally controls the large wheel to drive the rack to rotate.
[0068] like Figure 5 and Figure 6 As shown, the demolition assembly 5 includes:
[0069] A demolition knife 51 is provided in the door panel 11 and is located on a side of the connecting rod 423 away from the rotating handle 41 , with the blade of the demolition knife 51 facing the connecting rod 423 ;
[0070] The driving block 52 is fixedly connected to the demolition knife 51 , and a driving groove 113 is provided on the door panel 11 at a position corresponding to the demolition knife 51 . The driving groove 113 is perpendicular to the connecting rod 423 , and the driving block 52 slides in the driving groove 113 .
[0071] The sliding drive block 52 can manipulate the demolition knife 51 to cut off the connecting rod 423 at the corresponding position. Since the cross-sectional area of the connecting rod 423 is smaller than that of the fixed rod 421 and the rotating rod 422, it is easiest to cut the connecting rod 423 by using the demolition knife 51. After cutting the connecting rod 423, the adjustment block 33 can be manually slid to move the limiting column 32 out of the limiting hole 21, thereby opening the viewing window 12.
[0072] The design principle of the present invention is: by rotating the handle 41, the connecting rod driving part 42 and the gear driving part 43 can be driven to quickly and effectively drive the limit column 32 to move in the limit hole 21, so that the visual window 12 can be locked and opened at any time. If after an accident in the aircraft, the connecting rod driving part 42 and the gear driving part 43 are damaged, the visual window 12 cannot be opened by rotating the handle 41 and the cabin door body 1 cannot be opened by the door lock 112 for escape, at this time, the driving block 52 can be manually slid to drive the demolition knife 51 to cut off the connecting rod 423, and then the adjustment block 33 can be manually slid to move the limit column 32 out of the limit hole 21, so that the visual window 12 can be opened for escape.
[0073] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
