Description

Technical Field

[0001] This invention belongs to the field of helicopter overall design technology, and particularly relates to a helicopter cockpit restriction sign display and display method. Background Technology

[0002] Currently, the restriction signs in existing helicopter cockpits are distributed in various locations. For example, restriction signs are placed in the center of the cockpit, door opening signs are placed on the door handles, emergency evacuation signs are placed near the emergency exits, and no-smoking signs are placed on the rear bulkhead of the cockpit. Under normal circumstances, there are only 4 to 5 signs, which is a small number and widely distributed. The scattered signage not only distracts the pilot, but also makes the information cluttered and difficult to see clearly during nighttime combat missions, in poor lighting conditions, or in the event of a helicopter crash. In critical situations, this seriously affects the pilot's response procedures and flight safety.

[0003] In addition, most of the important restriction signs are in the paper version of the flight manual. In emergency situations, pilots have to look them up in the manual themselves, which takes a long time and can affect the pilot's ability to fly the helicopter and monitor the system status. Summary of the Invention

[0004] As operational requirements continue to increase, it becomes increasingly difficult to observe and use restricted signs in a quiet, dark cockpit. Therefore, there is an urgent need for centralized and unified management and control of restricted signs, enabling them to be located and used as needed.

[0005] The present invention is implemented using the following technical solution.

[0006] In a first aspect, the present invention provides a helicopter cockpit restriction sign display, wherein the restriction sign display 26 is mounted on a cylindrical structural member 27 in the center of the cockpit, the restriction sign display 26 is secured to the cylindrical structural member 27 by double clamps 22, and the double clamps 22 are fixed to the back of the restriction sign display 26; the restriction sign display 26 can be adjusted up and down or left and right along the cylindrical structural member 27, and the cylindrical structural member 27 is mounted on the structural frame beam in the middle of the cockpit by countersunk bolts;

[0007] The signage display 26 has a charging port 19 for connecting a charging cable connector 25;

[0008] Four self-reset buttons are arranged on the top, bottom, left, and right sides of the front of the restriction sign display 26, respectively, and are designated as self-reset button one, self-reset button two, ..., self-reset button sixteen. Self-reset button one, self-reset button two, ..., self-reset button sixteen can be controlled separately to display various types of restriction signs.

[0009] Furthermore,

[0010] Two elastic buckles 23 are installed on both sides of the middle part of the charging cable connector 25. One end of the charging cable connector 25 is two semi-circular connectors 24, and the other end of the charging cable connector 25 is a power cord.

[0011] Hold the two elastic clips 23, and the elastic clips 23 will press the semi-circular connector 24, causing the two semi-circular connectors 24 to deform and come together tightly; release the two elastic clips 23, and the elastic clips 23 can return to their original positions, and the semi-circular connectors 24 can also return to their original positions.

[0012] Furthermore,

[0013] The bottom of the restriction sign display 26 is provided with a charging socket 19. There is a miniature clamp inside the charging socket 19. After holding the elastic buckles 23 on both sides of the charging cable connector 25 and inserting it into the charging socket 19, the semi-circular connector 24 will lock onto the miniature clamp inside the charging socket 19 after releasing the hand, thus completing the self-locking.

[0014] Furthermore,

[0015] A light sensor 17 is installed in the upper left corner of the front of the restriction sign display 26 to automatically adjust the brightness of the display screen according to the intensity of external light.

[0016] The restriction sign display 26 adopts three display modes, namely "day", "automatic" and "night" modes. The three display modes are controlled by a three-position lever switch 18, which is installed on the left side of the restriction sign display 26.

[0017] When the three-position handle switch 18 is moved upwards to "Day" mode, the display shows white text on a black background. When the three-position handle switch 18 is moved downwards to "Night" mode, the display shows black text on a white background. When the three-position handle switch 18 is moved to the neutral position to "Auto" mode, the display mode can be automatically adjusted according to the light sensor 17. When the light sensor 17 detects that the light intensity is less than the preset intensity, it automatically switches to "Night" mode. When the light sensor 17 detects that the light intensity is not less than the preset intensity, it automatically switches to "Day" mode.

[0018] Furthermore,

[0019] The restriction sign display 26 has two protrusions on its back, and square rechargeable batteries 21 are respectively installed on the two protrusions.

[0020] Furthermore,

[0021] A square self-reset switch 20 is provided on the right side of the restriction sign display 26 to turn the display on and off; the display's on interface is the same as the display interface of the self-reset button.

[0022] Secondly, the present invention also provides a method for displaying restriction signs in a helicopter cockpit, implemented using the aforementioned restriction sign display, the method comprising:

[0023] Press and hold the square self-reset switch 20, and the restriction sign display 26 will be in the "on" state;

[0024] Self-reset button 1, self-reset button 2, ..., self-reset button 16, each has a corresponding restriction label engraved on it;

[0025] The driver can press the corresponding self-reset button as needed to obtain the restriction sign information corresponding to that button.

[0026] Furthermore, each of the self-reset buttons (1, 2, ..., 16) is engraved with a corresponding restriction label, specifically:

[0027] The self-reset button 1 is engraved with "Team", indicating "Team Personnel Configuration Identification";

[0028] The self-reset button 2 is engraved with "Hatch Door", indicating "Hatch Door Opening Method Sign";

[0029] The self-reset button 3 is engraved with "Window", indicating "Window opening and closing method label";

[0030] The self-reset button 4 is engraved with "Emergency", indicating "Emergency Exit Opening Method Indicator";

[0031] The self-reset button 5 is engraved with "No Smoking", indicating a "No Smoking Sign";

[0032] The self-reset button 6 is engraved with "Model", indicating "the helicopter's model designation";

[0033] The self-reset button 7 is engraved with "external suspension", indicating "maximum weight marking for external suspension";

[0034] The self-reset button 8 is engraved with "variable", indicating "expandable other restriction indicators"; this button can be set with multiple restriction indicators, and when the button is pressed successively, other restriction indicators will be displayed in sequence;

[0035] The self-reset button 9 is engraved with "slope", indicating "helicopter take-off and landing slope restriction sign";

[0036] The self-reset button 10 is engraved with "Altitude", indicating "maximum flight altitude of the helicopter";

[0037] The self-reset button 11 is engraved with "Restriction", indicating "Helicopter Restriction Marking";

[0063] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0064] This invention provides a helicopter cockpit restriction display that centrally displays restriction signs within the cockpit. This not only significantly increases the number of signs displayed but also improves pilot visibility of all flight restriction information in low-light conditions, allowing for faster access to all signs. Furthermore, the unified display of numerous flight restriction information enhances ease of use. Figures 1 to 19 As shown.

[0065] A method for displaying restrictions in a helicopter cockpit, which uses a restriction display to display the contents of multiple restriction signs individually;

[0066] like Figure 1 and Figure 2 As shown, a restriction display 26 is mounted on a cylindrical structural member 25 in the center of the cockpit. The restriction display 26 is secured to the cylindrical structural member 27 using double clamps 22, which are also fixed to the back of the restriction display 26. The restriction display 26 can be adjusted downwards or left and right along the cylindrical structural member 27, allowing drivers in different positions to adjust it according to their seating height and viewing direction. The cylindrical structural member 27 is mounted on the structural frame beam in the center of the cockpit using four countersunk bolts. The restriction display 26 has a charging port 19 for connecting a charging cable connector 25.

[0067] A charging cable connector 25 has two elastic clips 23 installed on both sides. When the two elastic clips 23 are held, they press against the semi-circular connector 24, causing the two semi-circular connectors 24 to deform and come together tightly. When the two elastic clips 23 are released, they return to their original positions, and the semi-circular connectors 24 also return to their original positions. Figure 3 As shown.

[0068] A charging port 19 is arranged at the bottom of the display 26. The charging port 19 has a miniature clamp. After holding the elastic buckles 23 on both sides of the charging cable connector 25 and inserting it into the charging port 19, the semi-circular connector 24 is locked onto the miniature clamp in the charging port 19 after releasing the hand, thus completing the self-locking and preventing the charging cable connector 25 from falling off due to the strong vibration of the helicopter, which would cause a power outage and affect the display of the logo.

[0069] A light sensor 17 is arranged in front of the display 26 to automatically adjust the brightness of the display screen according to the intensity of external light.

[0070] A restriction display 26 employs three display modes: "Day," "Auto," and "Night." These three modes are controlled by a three-position toggle switch 18, which is located on the left side of the restriction display. When the toggle switch 18 is moved upwards to "Day" mode, the display shows white text on a black background; when moved downwards to "Night" mode, the display shows black text on a white background. When the toggle switch 18 is moved to the neutral position to "Auto" mode, the display mode is automatically adjusted based on a light sensor 17. When the light sensor 17 detects weak light, it automatically switches to "Night" mode; when the light sensor 17 detects strong light, it automatically switches to "Day" mode.

[0071] Two square rechargeable batteries 21 are installed on two protrusions on the back of a limiting display 26. They can continue to be used even after the charging cable connector 25 is dropped or the power is cut off in an emergency, which increases the reliability of the limiting display. In the same space, the square rechargeable batteries 21 can charge a larger volume of energy than cylindrical batteries.

[0072] A square self-reset switch 20 is arranged on the right side of a restriction display 26, which can be used to turn the restriction display 26 on and off. When the restriction display 26 is in the "on" state, pressing and holding the square self-reset switch 20 for more than 3 seconds can turn the restriction display 26 off. When the restriction display 26 is in the "off" state, pressing and holding the square self-reset switch 20 for more than 3 seconds can turn the restriction display 26 on. The on interface of the restriction display 26 is the display interface of the self-reset button 1.

[0073] Four self-reset buttons are arranged on the top, bottom, left, and right sides of the front of a display 26. These are self-reset button 1, self-reset button 2, ..., self-reset button 16.

[0074] The self-reset button 1 is engraved with "crew," indicating "crew personnel configuration identification." See the label for details. Figure 4 As shown;

[0075] The self-reset button 2 is engraved with "Hatch Door," indicating "Hatch Door Opening Method Sign." See the sign for details. Figure 5 As shown;

[0076] The self-reset button 3 is engraved with "Window," indicating "Window opening and closing method label." See the label for details. Figure 6 As shown;

[0077] The self-reset button 4 is engraved with "Emergency," indicating "Emergency Exit Opening Method Indication." See the label for details. Figure 7 As shown;

[0078] The self-reset button 5 is engraved with "No Smoking," indicating a "No Smoking Sign." See the label for details. Figure 8 As shown;

[0079] The self-reset button 6 is engraved with "Model," indicating "helicopter model designation." See the label for details. Figure 9 As shown;

[0080] The self-reset button 7 is engraved with "external suspension," indicating "maximum weight marking for external suspension." See the label for details. Figure 10 As shown;

[0081] The self-reset button 8 is engraved with "Variable," indicating "expandable additional restriction indicators." This button can be set with multiple restriction indicators; when the button is pressed sequentially, other restriction indicators will be displayed in turn. See the label content below. Figure 11 As shown;

[0082] The self-reset button 9 is engraved with "Slope," indicating "Helicopter Takeoff and Landing Slope Limitation Sign." See the sign for details. Figure 12 As shown;

[0083] The self-reset button 10 is engraved with "Altitude," indicating "maximum flight altitude indicator for helicopters." See the label for details. Figure 13 As shown;

[0084] The self-reset button 11 is engraved with "Restriction," indicating a "helicopter restriction marking." See the label for details. Figure 14 As shown;

[0085] The self-reset button 12 is engraved with "Type," indicating "Helicopter Operation Type Identification." See the label for details. Figure 15 As shown;

[0088] The self-reset button 15 is engraved with "Center of Gravity," indicating "the lateral and longitudinal center of gravity markers for the helicopter." See the marker content below. Figure 18 As shown;

[0089] The self-reset button 16 is engraved with "Weight," indicating "Helicopter Operating Weight Plate." See the plate for details. Figure 19 As shown;

[0090] Specifically,

[0091] A method for displaying restrictions in a helicopter cockpit, using a restriction display 26 to display the contents of multiple restriction signs individually;

[0092] A restraint display 26 is mounted on a cylindrical structural member 3 in the center of the cockpit. The restraint display 26 is secured to the cylindrical structural member 25 using double clamps 22, which are fixed to the back of the restraint display 26. The restraint display 26 can be adjusted up and down or left and right along the cylindrical structural member 25. The cylindrical structural member 25 is mounted on the structural frame beam in the center of the cockpit using four countersunk bolts, with the mounting plane of the countersunk bolts flush with the upper plane.

[0093] A charging cable connector 25 has two elastic clips 23 installed on both sides. When the two elastic clips 23 are held, the elastic clips 23 will press the semi-circular elastic clips 24, causing the two semi-circular elastic clips 24 to deform and come together. When the two elastic clips 23 are released, the elastic clips 23 stop deforming, and the semi-circular elastic clips 24 also stop deforming.

[0094] A self-locking charging socket 19 is arranged at the bottom of the display 26. The charging socket 19 has a miniature clamp. After holding the elastic buckles 23 on both sides of the charging cable connector 25 and inserting it into the charging socket 19, the semi-circular elastic buckle 24 will lock onto the miniature clamp inside the charging socket 19 after releasing the hand, thus completing the self-locking.

[0095] A light sensor 19 is arranged in the upper left corner of the front of a display 26.

[0096] A restriction display 26 employs three display modes: "Day," "Auto," and "Night." These three modes are controlled by a three-position toggle switch 18, which is located on the left side of the restriction display. When the toggle switch 18 is moved upwards to "Day" mode, the display shows white text on a black background. When the toggle switch 18 is moved to the neutral position to "Auto" mode, the display mode automatically adjusts based on the light sensor 17. If the light sensor 17 detects low light, it automatically switches to "Night" mode; if the light sensor 17 detects high light, it automatically switches back to "Day" mode. When the toggle switch is moved downwards to "Night" mode, the display shows black text on a white background.

[0097] Two square rechargeable batteries 21 are mounted on two protrusions on the back of a display 26.

[0098] A square self-reset switch 20 is arranged on the right side of a restriction display 26, which can be used to turn the restriction display 26 on and off. When the restriction display 26 is in the "on" state, pressing and holding the square self-reset switch 20 for more than 3 seconds can turn the restriction display 26 off. When the restriction display 26 is in the "off" state, pressing and holding the square self-reset switch 20 for more than 3 seconds can turn the restriction display 26 on. The system's opening interface is the same as the display interface of the self-reset button 1, both being the crew personnel configuration interface.

[0099] Four self-reset buttons are arranged on the top, bottom, left, and right sides of the front of a limiting display 26. These are self-reset button 1, self-reset button 1, ..., self-reset button 16. The self-reset button 1 is engraved with the word "Unit".

[0100] The self-reset button 2 is engraved with "Hatch Door". The self-reset button 3 is engraved with "Window". The self-reset button 4 is engraved with "Emergency". The self-reset button 5 is engraved with "No Smoking". The self-reset button 6 is engraved with "Model". The self-reset button 7 is engraved with "External Suspension". The self-reset button 8 is engraved with "Variable". The self-reset button 9 is engraved with "Slope"; the self-reset button 10 is engraved with "Height"; the self-reset button 11 is engraved with "Restriction"; the self-reset button 12 is engraved with "Type"; the self-reset button 13 is engraved with "Temperature"; the self-reset button 14 is engraved with "Load Capacity"; the self-reset button 15 is engraved with "Center of Gravity"; and the self-reset button 16 is engraved with "Weight".

[0101] A helicopter cockpit upper control panel is mounted on the upper structure of the helicopter cockpit. It can transmit the lateral and longitudinal shear forces of the helicopter without the need for additional lateral and longitudinal frame beams to improve the structural strength, thus reducing the weight of the airframe. A restriction display 26 is used to display the contents of multiple restriction signs individually, avoiding pilot distraction during normal flight and allowing for the display of multiple restriction signs. The restriction display 26 is mounted on a cylindrical structural member 3 in the center of the cockpit. The restriction display 1 is secured to the cylindrical structural member 25 using double clamps 22, which are fixed to the back of the restriction display 26. The restriction display 26 can be adjusted up and down or left and right along the cylindrical structural member 25. The cylindrical structural member 25 is mounted on the structural frame beam in the center of the cockpit using four countersunk bolts, with the mounting plane of the countersunk bolts flush with the upper plane. The charging cable connector 25 has two elastic clips 23 on both sides. When the two elastic clips 23 are held, they press against the semi-circular elastic clips 24, causing them to deform and come together. When the two elastic clips 23 are released, they stop deforming, and the semi-circular elastic clips 24 also stop deforming. A self-locking charging socket 19 is located at the bottom of the display 26. The charging socket 19 contains a miniature clamp. When the elastic clips 23 on both sides of the charging cable connector 25 are held and the cable is inserted into the charging socket 19, releasing the cable will cause the semi-circular elastic clips 24 to engage with the miniature clamp inside the charging socket 19, completing the self-locking process. A light sensor 19 is located in the upper left corner of the front of the display 26 to detect light and automatically change the displayed color. The display 26 uses three display modes: "Day," "Auto," and "Night," controlled by a three-position lever switch 18. Two square rechargeable batteries 21 are installed on two protrusions on the back of the restriction display 26, which can still power the display in the event of a power outage, meeting the usage requirements. A square self-reset switch 20 is arranged on the right side of the restriction display 26, which can be used to turn the restriction display 26 on and off. The restriction display 26 has 16 self-reset buttons, which can display multiple restriction signs.
