Description

Technical Field

[0001] The invention belongs to the technical field of overall helicopter design, and in particular relates to a helicopter cockpit restriction sign display and a display method. Background Art

[0002] At present, the restriction display signs of existing helicopter cockpits are set in different positions, such as the restriction sign is arranged in the middle of the cockpit, the door opening sign is arranged at the door handrail, the emergency evacuation sign is arranged near the emergency exit, and the no smoking sign is arranged on the rear wall of the cockpit. Under normal circumstances, there are only 4 to 5 signs, which are relatively small in number and widely distributed. The scattered sign information not only distracts the driver's attention, but also makes the sign information messy and difficult to observe clearly when performing combat missions at night, in weak lighting environments, or when the helicopter crashes. In the event of a helicopter emergency, it seriously affects the handling procedures and flight safety.

[0003] In addition, most important restriction signs are in the paper version of the flight manual. In an emergency, the pilot needs to look up the manual by himself, which takes a long time and affects the pilot's ability to fly the helicopter and monitor the system status. Summary of the invention

[0004] With the continuous increase in combat use requirements, it is more difficult to observe and use restricted use signs in a dark cockpit. Therefore, there is an urgent need to centrally manage and control restricted signs so that they can be searched and used as needed.

[0005] The present invention is implemented by adopting the following technical scheme.

[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, and the restriction sign display 26 is clamped on the cylindrical structural member 27 by a double clamp 22, and the double clamp 22 is 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 a countersunk bolt;

[0007] A charging socket 19 is provided on the restriction sign display 26 for connecting a charging cable connector 25;

[0008] Four self-reset buttons are arranged on the top, bottom, left and right of the front of the restriction sign display 26, respectively, and are recorded 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 of the charging cable connector 25. One end of the charging cable connector 25 is two semicircular connectors 24, and the other end of the charging cable connector 25 is a power cord;

[0011] Holding the two elastic buckles 23, the elastic buckles 23 will press the semicircular joints 24, causing the two semicircular joints 24 to deform and come close together; releasing the two elastic buckles 23, the elastic buckles 23 can return to their original positions, and the semicircular joints 24 can also return to their original positions.

[0012] Furthermore,

[0013] A charging socket 19 is arranged at the bottom of the restriction sign display 26. A micro clamp is arranged inside the charging socket 19. After holding the elastic buckles 23 on both sides of the charging line connector 25 and inserting it into the charging socket 19, the semicircular connector 24 is clamped on the micro clamp inside the charging socket 19 after letting go, completing self-locking.

[0014] Furthermore,

[0015] A light sensor 17 is provided at the upper left corner of the front side of the restriction sign display 26 to automatically adjust the brightness of the display screen according to the external light intensity;

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

[0017] When the three-position handle toggle switch 18 is turned upward to the "day" mode, the display content of the display is displayed in black text on a white background. When the three-position handle toggle switch 18 is turned downward to the "night" mode, the display content of the display is displayed in white text on a black background. When the three-position handle toggle switch 18 is turned to the neutral position to the "automatic" mode, the display mode can be automatically adjusted according to the light sensor 17. When the light sensor 17 senses that the light intensity is less than the preset intensity, it automatically switches to the "night" mode. When the light sensor 17 senses that the light intensity is not less than the preset intensity, it automatically switches to the "day" mode.

[0018] Furthermore,

[0019] Two bosses are arranged on the back of the restriction sign display 26 , and square rechargeable batteries 21 are respectively installed on the two bosses.

[0063] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings.

[0064] The embodiment of the present invention provides a helicopter cockpit restriction display, which uses a restriction display to display restriction signs in the cockpit in a centralized and unified manner, which not only greatly increases the number of displayed signs, but also improves the pilot's ability to learn all flight restriction sign information in a short time under weak lighting conditions, and can display a large amount of flight restriction information in a unified and centralized manner, which is convenient to use. Figures 1 to 19 shown.

[0065] A helicopter cockpit restriction display method uses a restriction display to display the contents of multiple restriction signs separately;

[0066] like Figure 1 and Figure 2 As shown, a limit display 26 is installed on the cylindrical structure 25 in the center of the cockpit. The limit display 26 is clamped on the cylindrical structure 27 by a double clamp 22, and the double clamp 22 is fixed to the back of the limit display 26. The limit display 26 can be adjusted along the bottom or left and right of the cylindrical structure 27, which is convenient for drivers in different positions to adjust according to the sitting height and viewing direction. The cylindrical structure 27 is installed on the structural frame beam in the middle of the cockpit by four countersunk bolts. A charging socket 19 is provided on the limit display 26 for connecting the charging cable connector 25.

[0067] A charging cable connector 25, with two elastic buckles 23 installed on both sides. When the two elastic buckles 23 are held, the elastic buckles 23 press the semicircular connector 24, causing the two semicircular connectors 24 to deform and come close together; when the two elastic buckles 23 are released, the elastic buckles 23 can return to their original positions, and the semicircular connectors 24 can also return to their original positions.
