Description

Technical Field

[0001] This disclosure relates to the technical field of securing devices used on aircraft, and more specifically, to a securing device for reliably holding an electronic flight bag (EFB) within an aircraft, particularly a bracket mounted on the control panel of an aircraft cockpit for holding the electronic flight bag. Background Technology

[0002] An EFB (Electronic Flight Bag) is an electronic display system used in the cockpit or cabin of an aircraft. It can display various aviation information data or perform basic calculations (such as performance data, fuel calculations, etc.). Currently, the existing EFB brackets on mainstream aircraft models can only accommodate EFBs of limited sizes, lacking flexibility. Furthermore, when the aircraft's tilt changes, the existing EFB brackets cannot adapt well to changes in flight attitude, potentially limiting the pilot's field of vision. To facilitate the placement, retrieval, and viewing of electronic flight bags, an EFB bracket needs to be designed that can secure EFBs of different sizes while preventing them from falling due to strong airflow.

[0051] The specific embodiments of this utility model are described in detail below. This utility model provides a bracket for holding an electronic flight bag, which can be detachably mounted on the control panel of an aircraft cockpit and is suitable for fixing electronic flight bags (EFB) of different sizes.

[0052] As attached Figure 1-2 As shown, the bracket for holding the electronic flight bag according to the present invention includes a base 10 that can be detachably mounted on the control panel of the aircraft cockpit, an adjustment part 21 mounted on the base 10, a support plate 23 that can be positioned in different limiting slots 211 of the adjustment part 21 by means of a connecting rod 22, a base 31 mounted on the support plate 23 and capable of rotating relative to the support plate 23, and a mounting platform 41 mounted on the base 31 for placing the electronic flight bag. A ball joint assembly is provided between the mounting platform 41 and the base 31, so that when the aircraft tilts, the mounting platform 41 can tilt in the direction of the aircraft's tilt, thereby facilitating the pilot to view the data on the EFB.

[0053] The distal end of the adjusting part 21 is mounted on the base 10, and the proximal end of the adjusting part 21 extends towards the proximal side of the base 10. Furthermore, a U-shaped through-slot extending along the length of the adjusting part 21 and open on both sides is formed inside the adjusting part 21.

Figure 1 and 2The adjustment part 21 includes a fixed end 212 connected to the base 10 and an extension 213 extending proximally toward the base 10. The portion of the extension 213 connected to the fixed end 212 is designed with a smooth, curved shape, and the angle between the extension direction of the extension 213 and the extension direction of the base 10 is ≤15°. This facilitates not only the installation of the support plate 23 but also the adjustment of its installation position. See also the attached drawing. Figure 1 The support plate 23 has a first slot 231 at its distal end, which is longer than the width of the extension 213. First through holes are formed on the side walls of the first slot 231. The support plate 23 is first secured to the extension 213 through the first slot 231. Then, the connecting rod 22 passes through the first through hole and the limiting slot 211. Finally, the end of the connecting rod 22 is locked and fixed by fasteners, thereby fixing the distal end of the support plate 23 to the extension 21 of the adjustment part 21.

[0055] As attached Figure 3 As shown, the mounting platform 41 includes a platform 411 for placing and supporting an electronic flight bag, a groove 412 formed on two laterally opposite sides of the platform 411 and extending longitudinally along the platform 411, a slide plate 42 slidably disposed within the groove 412 in the lateral direction of the platform 411, and a first spring 43 disposed in the gap between the inner wall of the groove 412 and the slide plate 42. The lateral sidewall of the groove 412 has an opening that penetrates the platform 411, allowing the slide plate 42 to extend out from the opening. The slide plate 42 includes a first portion 421 located within the groove 412 and flush with the platform 411, and a second portion 422 located outside the opening of the groove 411 and extending perpendicularly to the first portion 421 in a direction away from the platform 411. One end of the first spring 43 is fixed to the inner wall of the groove 412, and the other end is fixed to the first portion 421 of the slide plate 42. In use, first place the electronic flight bag on the table 411. Adjust the distance between the second parts 422 of the slide plates 42 on both sides of the table 411 according to the size of the electronic flight bag placed on the table 411. With the help of the elastic force of the first spring 43, ensure that the second parts 422 of the slide plates 42 on both sides can clamp and fix the electronic flight bag, so that it can be used to fix electronic flight bags of different sizes.

[0056] As attached Figure 4As shown, the ball joint assembly includes a ball seat 51 mounted on a base 31, a ball 52 disposed within a cavity of the ball seat 51, and a connecting plate 53 disposed on top of the ball 52. The bottom of the ball seat 51 has external threads, and the base 31 has a fixing hole 311 corresponding to the ball seat 51 and having internal threads, thereby allowing the ball seat 51 to be fixed to the base 31 by a threaded connection. The connecting plate 53 has mounting holes 531, and the connecting plate 53 can be detachably fixed to the mounting platform 41 by fasteners passing through the mounting holes 531.

[0057] The proximal end of the base 31 is rotatably connected to the proximal end of the support plate 23 via the roller assembly 32, while the distal end of the base 31 is rotatably connected to the side wall of the support plate 23 via the connecting rod assembly 33. This allows the base 31 to be rotated relative to the support plate 23 to adjust the angle between the base 31 and the support plate 23, thereby adjusting the installation angle of the electronic flight bag.

[0058] Additionally, please refer to the appendix again. Figure 1 The roller assembly 32 includes a hollow sleeve 322 fixed to the bottom surface of the base 31 and connecting rods 321 fixed at both ends to the support plate 23. The connecting rods 321 pass through the internal cavity of the sleeve 322 and can rotate relative to the sleeve 322, thereby allowing the base 31 to flip relative to the support plate 23. Specifically, connecting ears are formed at both ends of the sleeve 322, and the sleeve 322 is fixed to the bottom surface of the base 31 through the connecting ears. A second slot 232 with a length greater than the length of the sleeve 322 is provided at the proximal end of the support plate 23, and second through holes are formed on the side walls on both sides of the second slot 232. The sleeve 322 can be placed in the second slot 232 first, and then the connecting rod 321 can be passed through the second through hole and the internal cavity of the sleeve 322, and then the end of the connecting rod 321 can be locked and fixed by fasteners.

[0059] See appendix for further details. Figure 1 The linkage assembly 33 includes two linkage sub-assemblies located on the lateral sides of the support plate 23. Each linkage sub-assembly includes a first connecting arm 331 with one end fixed to the base 31 and a second connecting arm 332 with one end fixed to the side wall of the support plate 23. The other end of the second connecting arm 332 is hinged to the other end of the first connecting arm 331. Preferably, the other end of the second connecting arm 332 is rotatably connected to the other end of the first connecting arm 331 by a pin, thereby supporting the base 31 when it is flipped relative to the support plate 23.

[0060] As attached Figure 5 As shown, the base 10 has recesses 101 on opposite sides in the lateral direction. Fixing components are provided at the recesses 101, and the bracket can be detachably installed on the control panel of the cockpit through the fixing components.

[0061] According to a preferred embodiment of the present invention, as shown in the appendix Figure 5 and 6 As shown, each fixing component includes a rotating shaft 11 rotatably disposed in the recess 101, a locking plate 12 with one end sleeved and fixed to the rotating shaft 11 and rotatable around the rotating shaft 11, and an angle adjustment mechanism for adjusting the direction of the locking plate 12. The two ends of the rotating shaft 11 are rotatably fixed to the side walls of opposite sides of the recess 101. Preferably, the two ends of the rotating shaft 11 are fixed to the side walls of the recess 101 by bearings. The locking plate 12 rotates with the rotation of the rotating shaft 11, and the locking plate 12 is configured to engage with a locking hole on the control panel, thereby detachably mounting the bracket on the control panel of the cockpit, thus increasing the convenience of bracket installation.

[0062] See appendix Figure 5 and 6 The angle adjustment mechanism includes cavities 102 formed at two corners near the base 10, a ratchet 111 disposed within the cavities 102, and a pawl plate 13. The cavities 102 are adjacent to and aligned with the recesses 101. The ratchet 111 is disposed where the rotating shaft 11 passes through the end wall of the recess 101 and extends to the proximal end within the cavity 102. A rotating rod 14 is disposed within the cavity 102 and is parallel to the rotating shaft 11. The pawl plate 13 is rotatably disposed on the rotating rod 14. Preferably, the pawl plate 13 is designed with a bushing, and the rotating rod 14 passes through the hollow cavity of the bushing and is rotatable relative to the bushing, thereby allowing the pawl plate 13 to rotate relative to the rotating rod 14. One end of the pawl plate 13 is configured as a pawl 131 capable of engaging with the ratchet 111. By engaging different tooth phases of the pawl 131 with the ratchet 111, the latch plate 12 can be positioned in different directions, thereby enabling the latch plate 12 to engage with the latch hole on the operating table. The other end of the pawl plate 13 extends outward into the cavity 102 and is configured to disengage the pawl 131 from the ratchet 111 under pressure, thereby allowing the bracket to be removed from the operating table. Specifically, the side wall of the cavity 102 is provided with an opening 103 that allows the other end of the pawl plate 13 to extend outward, and a second spring 15 is provided on the lower side of the other end of the pawl plate 13 extending outward into the cavity 102, so that the pawl plate 13 can re-engage with the ratchet 111 under the elastic force of the second spring 15, thereby enabling the latch plate 12 to engage with the latch hole on the operating table.

[0063] According to a preferred embodiment of the present invention, the base 10 is provided with anti-slip protrusions 16, which can engage with the grippers on the operating table to prevent the bracket from sliding relative to the operating table during use. Specifically, the base 10 is designed with a groove 104 extending laterally along the base 10 and penetrating the upper and lower surfaces of the base 10 at the position between the adjustment part 21 and the fixing component. Anti-slip protrusions 16 are designed in the groove 104 and are evenly distributed along the length direction of the groove 104. The anti-slip protrusions 16 are configured to engage with the grippers on the operating table to prevent the bracket from sliding relative to the operating table.

[0064] The bracket provided by this utility model is adjustable and flexible, enabling it to adapt to the needs of electronic flight bags (EFBs) of different sizes and flight attitudes, and is suitable for effective use under various flight conditions. Specifically, the EFB is placed on the platform 411 of the mounting table 41. Slide plates 42, which can slide along the platform 411, are provided on opposite sides of the platform 411. Under the action of elasticity, the second part 422 of the slide plates 42 can clamp and hold the EFB. The distance between the second parts 422 of the slide plates 42 on both sides can be adjusted according to the size of the EFB to accommodate different sizes of EFBs. The mounting table 41 is mounted on the base 31 via a ball joint assembly, allowing for angle adjustment of the mounting table 41. When the aircraft tilts, the mounting table 41 can tilt in the same direction as the aircraft, thus facilitating the pilot's viewing of data on the EFB. The base 31 is constructed via a roller assembly 32 and a connecting rod assembly 33 to be able to rotate relative to the support plate 23, thereby adjusting the angle between the base 31 and the support plate 23 and adjusting the placement angle of the EFB. The support plate 23 can be positioned in different limiting slots 211 via the connecting rod 22, thereby adjusting the relative position of the support plate 23 and thus adjusting the placement position of the EFB.

[0065] Furthermore, in the bracket according to this utility model, the U-shaped through groove with open sides inside the adjustment part 21 effectively reduces the weight of the EFB bracket and avoids the problem of increased weight due to the increased function of the bracket.
