Abstract
Description
Technical Field
[0001] This invention relates to the field of adjustment device technology, and more particularly to an electronic flight manual fixed adjustment device. Background Technology
[0002] With the increasing integration of electronic equipment in modern aircraft cockpits, traditional paper-based aeronautical chart manuals have been gradually replaced by electronic flight bags (EFBs). According to FAA AC 120-76D standards, over 90% of airlines use Class 1 or Class 2 EFB systems, with 65% choosing tablets as display terminals. While this change has improved data update efficiency, it has brought challenges to equipment mounting—the Boeing 787 cockpit design specifications explicitly require that any new equipment must not obstruct the pilot's normal operating space (SAE ARP5056 standard). Current solutions often employ simple elastic straps or magnetic brackets, which cannot meet the requirements for maintaining a view during changes in flight attitude.
[0003] Existing adjustment devices include three methods: instrument panel embedded mounting brackets, knee plate fixing solutions, and suction cup temporary brackets. Instrument panel embedded mounting brackets fix the flat panel to the side of the center console using an aluminum alloy frame. The advantage is good stability, but the disadvantage is that the viewing angle is fixed and cannot be adjusted, and it occupies maintenance passage space. Knee plate fixing solutions use carbon fiber brackets to fix the panel to the pilot's thigh plate. The advantage is that it can move with the body, but it hinders the push-pull stroke of the emergency control stick. Suction cup temporary brackets use vacuum suction cups to adhere to the windshield. The advantage is flexible installation, but there is a risk of detachment in low-pressure environments. Therefore, existing adjustment devices have drawbacks: the fixing method affects the normal working space of flight control devices, the lack of three-dimensional spatial adjustment capability leads to poor reading angle, and the fixing reliability is insufficient in vibration environments, affecting the normal flight of the aircraft.

[0050] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0051] To facilitate the mounting of the tablet equipment and make it easier for aircraft pilots to view, such as Figure 1 As shown, this invention proposes an electronic flight manual fixing and adjustment device, comprising: a base 100, a universal joint 200, a first plate 300, a second plate 400, a insert plate 700, a cylinder 1000, and a circular plate 1100. Specifically, as...Figure 2 and Figure 3 As shown in the figure, the universal joint 200 is fixedly installed on the outer surface of the base 100, and the base 100 is fixed on the aircraft through locking bolts, wherein the universal joint 200 is a ball joint, which allows the connection mechanism to rotate or swing in multiple directions, and is a mature technology, and the present application does not improve it, so it will not be described in detail here. In order to limit the position of the tablet device, as shown in Figure 3 and Figure 4 The first plate 300 is fixedly installed at one end of the universal joint 200 and can adjust the orientation with the rotation and swing of the universal joint 200, and the second plate 400 is arranged at one end of the first plate 300. When in use, the tablet device is placed on the upper surfaces of the first plate 300 and the second plate 400. Since the end face of one end of the first plate 300 is provided with two insertion slots 320, the lower surface of the second plate 400 is fixedly installed with two insertion blocks 420, and the two insertion blocks 420 are respectively arranged inside the two insertion slots 320 and are slidingly installed with the inner walls of the insertion slots 320, so the second plate 400 can move along the central axis direction of the insertion slots 320. In addition, the outer surface of the first plate 300 is provided with a plurality of first protruding portions 310, and the upper surface of the second plate 400 is provided with a plurality of second protruding portions 410. When the second plate 400 moves along the central axis direction of the insertion slots 320 and moves close to the first plate 300, the tablet device is clamped by the plurality of second protruding portions 410 and the plurality of first protruding portions 310, thereby limiting the position of the tablet device.
[0052] In order to fix the relative position of the second plate 400 and the first plate 300, as shown in Figure 4 , Figure 5 and Figure 6 The insertion plate 700 is fixedly installed on the lower surface of the second plate 400, the outer surface of the insertion plate 700 is provided with a limiting slot 710, the cylindrical body 1000 and the circular plate 1100 are arranged on the lower surface of the first plate 300, the circular plate 1100 is fixedly installed at one end of the cylindrical body 1000, the cylindrical body 1000 is slidingly installed between the inner walls of the limiting slot 710, the diameter of the circular plate 1100 is greater than the slot width of the limiting slot 710, and the circular plate 1100 is arranged to move the circular plate 1100 close to the insertion plate 700 when the cylindrical body 1000 rotates around its central axis. Directional movement, the circular plate 1100 can press the outer surface of the insertion plate 700, thereby limiting the position of the insertion plate 700, and further fixing the relative position of the second plate 400 and the first plate 300. Through the above arrangement, the position of the tablet device can be fixed, so that the adjusting device can limit and fix the tablet device. In actual use, the stability of the tablet device can be ensured, and the angle can be adjusted arbitrarily in three-dimensional space, thereby ensuring the normal flight of the aircraft.
[0053] In this embodiment, in order to enable the cylinder 1000 to rotate around its own central axis, as shown in Figure 5 , Figure 6 and Figure 13 , a fixed ring 600 is fixedly installed on the lower surface of the first plate 300, a circular hole 610 is formed in the inside of the fixed ring 600, the cylinder 1000 is rotatably installed between the inner walls of the circular hole 610, and a knob 500 is fixedly installed at the other end of the cylinder 1000 and penetrates the circular hole 610. During use, the knob 500 is manually rotated to drive the cylinder 1000 to rotate around its own central axis, and the direction of manually rotating the knob 500 is shown by the arrow direction in Figure 1 .
[0054] In order to enable the cylinder 1000 to rotate around its own central axis, the circular plate 1100 can be driven to move towards the plug plate 700, as shown in Figure 6 and Figure 11 , a through groove 1010 is formed through the circumferential outer surface of the cylinder 1000, a weight block 1400 is slidably installed on the inner wall of the through groove 1010, a hole 1430 is formed through the upper surface of the weight block 1400, a circular ring 1200 is sleeved on the circumferential outer surface of the cylinder 1000, a connecting rod 1210 is fixedly installed between the inner walls of the circular ring 1200, the connecting rod 1210 penetrates the hole 1430 and is slidably installed on the inner wall thereof, a third spring 1450 is fixedly connected to one end of the weight block 1400 close to the knob 500, a sliding block 1440 is fixedly connected to the other end of the third spring 1450, the outer surface of the sliding block 1440 abuts against and is slidably installed on the inner wall of the through groove 1010, the weight block 1400 can slide in the through groove 1010 through the sliding block 1440, a second limiting column 1460 is fixedly connected to one end of the weight block 1400 close to the knob 500, a first ring groove 620 is formed in the outer surface of one end of the fixed ring 600 close to the knob 500, a triangular protrusion 650 is fixedly installed on the inner wall of the first ring groove 620, as shown in Figure 12 , a spherical protrusion 1220 is arranged on the outer surface of one side of the circular ring 1200 close to the fixed ring 600, when the cylinder 1000 rotates, it drives the circular ring 1200 to rotate around the central axis of the cylinder 1000, thereby driving the spherical protrusion 1220 to move towards the triangular protrusion 650, when the spherical protrusion 1220 abuts against the triangular protrusion 650, it drives the weight block 1400 to move towards the knob 500, until the second limiting column 1460 abuts against the sliding block 1440, it drives the circular plate 1100 to move towards the plug plate 700, thereby compressing the plug plate 700, so that the relative positions of the second plate 400 and the first plate 300 are fixed.
[0055] Because the tablet device is put on the upper surface of the first plate 300 and the second plate 400, the tablet device is clamped by manually pushing the second plate 400 to move close to the first plate 300, and then the position of the second plate 400 is locked by the round plate 1100 pressing the plug plate 700, because the force of manually pushing the second plate 400 to move is different, in order to prevent the second plate 400 and the second protruding part 410 on the first plate 300 and the first protruding part 310 from not clamping the tablet device, as shown in Figure 7 and Figure 8 The bottom wall of the limiting groove 710 is fixedly installed with a first sawtooth plate 800, and a plurality of triangular sawteeth are equidistantly arranged on the outer surface of the first sawtooth plate 800, as shown in Figure 15 The other end of the weight block 1400 is fixedly installed with a clamping block 1500, the clamping block 1500 is triangularly arranged, and the clamping block 1500 is in abutment with the triangular sawteeth on the outer surface of the first sawtooth plate 800. When the cylinder 1000 rotates, because of the gravity of the weight block 1400 itself, the clamping block 1500 will slide along the inner wall of the through groove 1010, so that the clamping block 1500 slides out of the through groove 1010 when it rotates to the direction close to the first sawtooth plate 800. At this time, the tip of the clamping block 1500 is inserted between the adjacent two triangular sawteeth, and as the cylinder 1000 continues to rotate, the clamping block 1500 drives the first sawtooth plate 800 to move in the direction close to the first plate 300, so that the second plate 400 moves in the direction close to the first plate 300. Through the above arrangement, the second plate 400 can be moved a fixed distance in the direction of the first plate 300 before being fixed, so that the clamping force between the second protruding part 410 and the first protruding part 310 is larger, preventing the tablet device from slipping off. Because, as shown in Figure 11 , Figure 12 , Figure 13 and Figure 14 The upper surface of the weight block 1400 is provided with a triangular stop block 1410, which is in abutment with the triangular protrusion 650. When the weight block 1400 drives the triangular stop block 1410 to abut against the triangular protrusion 650, the cylinder 1000 stops rotating. At this time, the clamping force of the tablet device is certain, which can ensure that the tablet device is clamped. It should be noted that the triangular stop block 1410 is in abutment with the side of the triangular protrusion 650, and the spherical protrusion 1220 is in abutment with the end face of the triangular protrusion 650, and the two do not interfere with each other. The spherical protrusion 1220 contacts the triangular protrusion 650 first, and then the triangular stop block 1410 contacts the triangular protrusion 650. The advantage of this arrangement is that when the clamping block 1500 drives the second plate 400 to move in the direction close to the first plate 300 through the first sawtooth plate 800, the round plate 1100 has not yet pressed the plug plate 700, so that the second plate 400 moves more easily. When the second plate 400 moves to the position, the round plate 1100 is pressed against the plug plate 700.
[0056] When the round plate 1100 is pressed against the plug plate 700, in order to ensure that the second plate 400 is fixed more firmly, prevent spacecraft vibration from affecting the loosening of the flat panel device, as shown in Figure 7 and Figure 8 , the bottom wall of the limiting groove 710 is provided with a mounting groove 720, the inner wall of the mounting groove 720 is slidably installed with a second sawtooth plate 900, the outer surface of the second sawtooth plate 900 is provided with a plurality of triangular sawteeth at equal intervals, as shown in Figure 15 and Figure 17 , the outer surface of the clamping block 1500 is provided with an inclined angle 1510, the inclined angle 1510 abuts against the triangular sawteeth on the outer surface of the second sawtooth plate 900, when the weight block 1400 moves towards the knob 500, it will drive the inclined angle 1510 to abut against the edge of the second sawtooth plate 900, and because, as shown in Figure 18 and Figure 19 , the inner wall of one end of the mounting groove 720 is provided with a limiting insertion hole, one end of the second sawtooth plate 900 is fixedly connected with a sliding column 930, the sliding column 930 is slidably inserted between the inner walls of the limiting insertion hole, the outer surface of the plug plate 700 is provided with an opening 730, the opening 730 is in communication with the limiting insertion hole, the other end of the second sawtooth plate 900 is fixedly connected with a first spring 920, the other end of the first spring 920 is fixedly connected with the inner wall of the mounting groove 720, the other end of the second sawtooth plate 900 is fixedly connected with a first limiting column 910, so that after the inclined angle 1510 abuts against the edge of the second sawtooth plate 900, it will drive the second sawtooth plate 900 to move towards the first plate 300, until the first limiting column 910 abuts against the inner wall of the mounting groove 720 close to the first plate 300, at this time, the second sawtooth plate 900 is completely aligned with the triangular sawteeth of the first sawtooth plate 800.
[0057] In order to limit the position of the second plate 400, as shown in Figure 9 , Figure 10 and Figure 14As shown, the inner part of the fixed ring 600 is provided with a square hole 640, the inner wall of the square hole 640 is slidably provided with a square inserting rod 1300, the outer surface of the fixed ring 600 near one end of the inserting plate 700 is provided with a second ring groove 630, the outer surface of the square inserting rod 1300 near one end of the inserting plate 700 is provided with a stop ring 1310, the outer surface of the square inserting rod 1300 is sleeved with a second spring 1320, one end of the second spring 1320 is fixedly connected with the outer surface of the stop ring 1310, the other end of the second spring 1320 is fixedly connected with the inner wall of the second ring groove 630, and one end of the square inserting rod 1300 abuts against the outer surface of the second sawtooth plate 900, when the triangular sawteeth of the second sawtooth plate 900 are completely aligned with the triangular sawteeth of the first sawtooth plate 800, the square inserting rod 1300 will be clamped between the adjacent two triangular sawteeth of the second sawtooth plate 900, and the position of the second sawtooth plate 900 is stopped, so that the second sawtooth plate 900 is prevented from loosening.
[0058] When the tablet device needs to be loosened, the knob 500 needs to be manually rotated in the reverse direction, at this time, the weight block 1400 will also rotate in the reverse direction, since the weight block 1400 is provided with the wedge-shaped block 1420, the outer surface of the stop ring 1310 is provided with the guide column 1311, the guide column 1311 abuts against the outer surface of the wedge-shaped block 1420 away from the inserting plate 700, and the outer surface of the wedge-shaped block 1420 is provided with two symmetrical inclined angles, when the wedge-shaped block 1420 starts to rotate to the position near the second sawtooth plate 900, the wedge-shaped block 1420 will abut against the guide column 1311, because the outer surface of the wedge-shaped block 1420 is provided with two symmetrical inclined angles, the square inserting rod 1300 will be retracted to the inside of the square hole 640 in the direction close to the knob 500, at this time, the second sawtooth plate 900 is limited by contact, and it needs to be noted that the wedge-shaped block 1420 always abuts against the guide column 1311 after the knob 500 is rotated by half a turn, so that the square inserting rod 1300 is always stopped in the square hole 640.
