Description

Technical Field

[0001] This invention relates to the field of aircraft ground maintenance technology, and in particular to a portable electronic flight bag mounting bracket and its installation method. Background Technology

[0002] Traditional flight bags are document pouches carried by pilots into the cockpit, containing various onboard manuals, navigation charts, and other paper reference materials. With technological advancements, traditional flight bags have been gradually replaced by electronic flight bags (EFBs). Portable EFBs have become widely used by airlines worldwide in recent years. The most common uses of EFBs are: 1) when the EFB needs to be charged in the cockpit; and 2) when the portable EFB needs to interact with other data interfaces in the cockpit. For example, the EFB can be connected via a data cable to the aircraft's "cabin video monitoring module" interface to facilitate real-time monitoring of the cabin via surveillance cameras; or when pilots use the EFB to view flight manuals, flight charts, and other flight data. For flight safety reasons, crew members must use brackets to secure the portable EFB when using it in the cockpit.

[0003] Currently, common electronic flight bag mounting brackets have the following structural defects: 1) The adjustment mechanism is complex, inconvenient to operate, and has poor reliability and durability; 2) In some aircraft models with small cockpits and limited installation space (such as the ERJ190 model), if the installation position is not properly selected, the electronic flight bag or mounting bracket may interfere with the pilot's body movements or obstruct the pilot's view, affecting the pilot's normal operation of the flight control mechanism, hindering the pilot's observation and use of control equipment and displays, and preventing the pilot from opening sliding windows for emergency evacuation, which may easily lead to safety accidents.

[0004] Meanwhile, existing electronic flight bag mounting brackets are mostly installed using adsorption or adhesive methods. Some are fixed to the control panel with hooks and loops, some are fixed to the window glass with suction cups, and some are attached to the bottom decorative panel of the sliding window with adhesive. As the time of use increases, the mounting brackets become less secure, and in emergency landing situations, the brackets may come loose, causing injuries and safety accidents. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a portable electronic flight bag mounting bracket and its installation method to overcome the deficiencies in existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A method for installing a mounting bracket for a portable electronic flight bag includes the following steps:

[0008] S1: Remove some of the rivets from the original support of the trim panel below the sliding window of the cockpit, so that the original support of the trim panel remains connected to the trim panel.

[0009] A fixed bracket is manufactured, the fixed bracket including a base assembly and a slide rail assembly, a connecting assembly and a tray assembly mounted on the base assembly;

[0010] The base assembly includes a first fixed base plate, a second fixed base plate, and a third fixed base plate. The first fixed base plate is installed on the top surface of the lower decorative panel of the aircraft sliding window, and the second and third fixed base plates are installed at intervals on the bottom surface of the lower decorative panel of the aircraft sliding window.

[0011] The first fixed base plate has two sets of mounting holes, which correspond to the two sets of mounting holes on the original decorative panel under the sliding window of the aircraft. The first set of mounting holes is used to connect and fix the first fixed base plate, the decorative panel, the second fixed base plate, and the original first support position of the decorative panel in sequence by rivets. The second set of mounting holes is used to connect and fix the first fixed base plate, the decorative panel, the third fixed base plate, and the original second support position of the decorative panel in sequence by rivets.

[0012] The slide rail assembly includes a slide rail, with limiting blocks fixedly installed at both ends of the slide rail, a slider slidably installed on the slide rail, a connecting plate fixedly installed on the slider, and a locking hook installed on the connecting plate; the slide rail assembly also includes a first locking mechanism installed at the front end of the slide rail and a second locking mechanism installed at the rear end of the slide rail.

[0013] The first locking mechanism includes a locking wrench that rotates about a pivot, the locking wrench being provided with a locking pin that engages with a locking hook, and the locking wrench being connected to a torsion spring;

[0014] The second locking mechanism includes a first ball groove formed at the rear end of the slide rail. A first return spring and a ball are installed in the first ball groove. Under the action of the first return spring, the top of the ball is higher than the top surface of the slide rail in the initial state, so that the ball can cooperate with the second ball groove on the bottom surface of the connecting plate on the sliding trajectory of the slider.

[0015] When the slider slides to the front end of the slide rail, the locking hook on the connecting plate engages with the first locking mechanism, and the slider is locked to the front end of the slide rail; when the slider slides to the rear end of the slide rail, the connecting plate engages with the second locking mechanism, and the slider is temporarily locked to the rear end of the slide rail.

[0016] The connection assembly includes a hinged base;

[0017] The tray assembly includes a hollow card seat, a slide rail slidably disposed at the open end of the card seat, the slide rail being inserted into the card seat in a drawer-like manner, a first claw disposed at the blind end of the card seat, a second claw disposed at the sliding end of the slide rail corresponding to the first claw, and a turntable disposed at the bottom of the card seat.

[0018] S2: Install a base assembly for a fixed bracket on the decorative panel; the first fixed base plate has a first set of mounting holes and a second set of mounting holes at both ends, which correspond to the two sets of rivet holes on the decorative panel. The first set of mounting holes is used to connect and fix the first fixed base plate, the decorative panel, the second fixed base plate, and the original support of the decorative panel in sequence by rivets; the second set of mounting holes is used to connect and fix the first fixed base plate, the decorative panel, the third fixed base plate, and the original support of the decorative panel in sequence by rivets, so that the two ends of the first fixed base plate are connected and fixed to the decorative panel and the original support by the second fixed base plate and the third fixed base plate, respectively.

[0019] S3: Install a fixed slide rail assembly on the first fixed base plate of the base assembly; so that the rear end of the slide rail is suspended and supported on the decorative panel by a support block fixed on the rear end of the slide rail, with the bottom surface of the support block in contact with the top surface of the decorative panel;

[0020] S4: Install the connecting component on the slide rail assembly;

[0021] S5: Install the tray assembly on the connecting assembly.

[0022] Furthermore, in step S3, the front end of the slide rail is screwed and fixed to the first fixed base plate; the third set of assembly holes in the middle of the first fixed base plate is used to screw the slide rail.

[0023] Further, in step S4, the hinge seat of the connecting assembly is installed on the slider.

[0024] Further, in step S5, the turntable of the tray assembly is mounted on the hinge seat in the connecting assembly.

[0025] Furthermore, the slide includes a guide slide rod inserted into the card seat, and a second return spring is sleeved on the guide slide rod. One end of the second return spring is fixed to the card seat, and the other end is fixed to the slide.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1) The installation method of the electronic flight bag mounting bracket in this case is to install the mounting bracket on the original decorative panel of the aircraft without damaging the original decorative panel and the original supporting components of the decorative panel, without affecting the pilot's daily operation, and without affecting the pilot's safe escape in special circumstances.

[0028] 2) The electronic flight bag mounting bracket in this case has its base assembly installed on the decorative panels and existing supports below the sliding windows on both sides of the cockpit, rather than directly on the main load-bearing window frame structure. Therefore, it has no significant impact on the structural strength of the sliding window frames. In the original aircraft configuration, the decorative panels and supports are connected by rivets. When installing this electronic flight bag mounting bracket, the existing mounting holes at the front of the decorative panels are used for fixing. This ensures that the modification of the electronic flight bag mounting bracket does not damage the original structure of the decorative panels and existing supports, thus complying with aircraft airworthiness standards.

[0029] 3) The electronic flight bag mounting bracket in this case is installed on the decorative panel below the sliding windows on both sides of the cockpit, near the original configuration chart holder. When the pilot is using the mounting bracket normally, the mounting bracket is in the forward-locked position. When it is necessary to open the sliding window, simply press the locking lever of the first locking mechanism and then push the tray assembly (or together with the electronic flight bag) backward to the temporary locking position of the second locking mechanism to open the sliding window normally. This will not affect the pilot's ability to open the window, will not affect emergency window opening, and will not affect the aircraft's safety performance.

Detailed Implementation

[0038] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0039] Furthermore, if terms such as "first" or "second" are used for descriptive purposes only, they are mainly used to distinguish different devices, components or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance or quantity of the indicated devices, components or parts, and should not be construed as indicating or implying relative importance.

[0040] Furthermore, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0041] Please also refer to Figure 1-7 The present invention provides a portable electronic flight bag mounting bracket, including a base assembly 1 and a slide rail assembly 2, a connecting assembly 3 and a tray assembly 4 mounted on the base assembly 1. The slide rail assembly 2 is mounted on the base assembly 1, and the connecting assembly 3 connects the tray assembly 4 and the slide rail assembly 2, so that the tray assembly 4 can slide on the slide rail assembly 2.

[0042] The base assembly 1 includes a first fixed base plate 11, a second fixed base plate 12, and a third fixed base plate 13. The first fixed base plate 11 is installed on the top surface of the lower decorative panel 9 of the aircraft sliding window, and the second fixed base plate 12 and the third fixed base plate 13 are installed at intervals on the bottom surface of the lower decorative panel 9 of the aircraft sliding window. Specifically, the first fixed base plate 11 has two sets of mounting holes, which correspond to the two sets of mounting holes on the lower decorative panel 9 of the aircraft sliding window. The first set of mounting holes is used to sequentially connect and fix the first fixed base plate 11, the decorative panel 9, the second fixed base plate 12, and the original first support position of the decorative panel 9 by rivets. The second set of mounting holes is used to sequentially connect and fix the first fixed base plate 11, the decorative panel 9, the third fixed base plate 13, and the original second support position of the decorative panel 9 by rivets. In this way, the two ends of the first fixed base plate 11 are connected and fixed to the decorative panel 9 and the original support components through the second fixed base plate 12 and the third fixed base plate 13 respectively, thereby ensuring that the installation of the first fixed base plate 11 meets the structural strength and stability requirements of aviation modification, and does not damage the original aircraft structure such as the decorative panel 9.

[0043] The slide rail assembly 2 includes a slide rail 21, with limiting blocks 22 fixedly disposed at both ends of the slide rail 21. A slider 23 is slidably disposed on the slide rail 21, and a connecting plate 24 is fixedly disposed on the slider 23. A locking hook 241 is disposed on the connecting plate 24. The slide rail assembly 2 also includes a first locking mechanism disposed at the front end of the slide rail 21 and a second locking mechanism disposed at the rear end of the slide rail 21. When the slider 23 slides to the front end of the slide rail 21, the locking hook 241 on the connecting plate 24 cooperates with the first locking mechanism, and the slider 23 is locked at the front end of the slide rail 21. When the slider 23 slides to the rear end of the slide rail 21, the connecting plate 24 cooperates with the second locking mechanism, and the slider 23 is temporarily locked at the rear end of the slide rail 21.

[0044] The first locking mechanism includes a locking lever 25 that rotates around a pivot. The locking lever 25 has a locking pin (not shown) that engages with a locking hook 241. The locking lever 25 is connected to a torsion spring (not shown). Under the action of the torsion spring, the locking lever 25 remains in its initial position. When the slider 23 slides to the front end of the slide rail 21, the locking hook 241 pushes open the locking pin, causing the locking lever 25 to rotate. This allows the locking hook 241 to engage with the locking pin on the locking lever 25, achieving the locking effect on the slider 23. When the locking lever 25 is manually rotated, it causes the locking pin to deflect, disengaging the locking hook 241 from the locking pin. The slider 23 is then released by the first locking mechanism and can slide freely on the slide rail 21. In this embodiment, the first locking mechanism locks the slider 23 at the front end of the slide rail 21, meaning the tray assembly 4 is locked at the front end of the slide rail 21. At this time, the aircraft sliding window is closed, and the pilot can use the electronic flight bag on the fixed bracket normally. Furthermore, when the first locking mechanism is unlocked, the pilot can unlock it simply by operating the locking lever 25 with one hand, making the operation simple and convenient.

[0045] The second locking mechanism includes a first ball groove (not shown) opened at the rear end of the slide rail 21. A first return spring (not shown) and a ball 26 are installed in the first ball groove. Under the action of the first return spring, the top of the ball 26 is higher than the top surface of the slide rail 21 in the initial state, so that the ball 26 can cooperate with the second ball groove on the bottom surface of the connecting plate 24 on the sliding trajectory of the slider 23. When the slider 23 slides to the rear end of the slide rail 21, the connecting plate 24 pushes the ball 26, and the ball 26 sinks into the first ball groove. When the second ball groove on the connecting plate 24 aligns with the first ball groove on the slide rail 21, the ball 26 is pushed up under the action of the first return spring, and the top of the ball 26 sinks into the second ball groove, achieving the effect of temporarily locking the slider 23. When an external force (such as the external force transmitted to the slider 23 by the push-pull tray assembly 4) overcomes the friction between the ball 26 and the second ball groove, the ball 26 disengages from the second ball groove, and the slider 23 is released by the second locking mechanism, allowing the slider 23 to slide freely on the slide rail 21. In this embodiment, the function of the second locking mechanism is to lock the slider 23 at the rear end of the slide rail 21, that is, the tray assembly 4 is locked at the rear end of the slide rail 21. At this time, the aircraft may be in a special state on the ground, and the pilot needs to open the sliding window for safe evacuation. The tray assembly 4 is locked at the rear end of the slide rail 21, which can prevent the fixed bracket or electronic flight bag from interfering with the pilot's operation of the sliding window handle when the pilot opens the sliding window backward, thus affecting the pilot's evacuation in emergency situations.

[0046] Preferably, in this embodiment, the slider 23 and the slide rail 21 are connected by a fitting. The fitting part between the slider 23 and the slide rail 21 is a pad made of nylon material. During the sliding of the slider 23 on the slide rail 21, the pad and the slide rail 21 rub against each other to generate damping, so that the fixed bracket can avoid sudden movement and safety hazards during the back-and-forth sliding process.

[0047] Preferably, in this embodiment, the limiting blocks 22 at the front and rear ends of the slide rail 21 are fixed to the slide rail 21 by countersunk screws. The function of the front and rear limiting blocks 22 is to limit the sliding of the slider 23 within the travel range of the slide rail 21.

[0048] Furthermore, the slide rail assembly 2 also includes a support block (not shown) disposed at the rear end of the slide rail 21. The support block is fixed to the bottom surface of the rear end of the slide rail 21, and the bottom of the support block is in contact with the decorative panel 9. The function of the support block is to prevent the structural stress form of the slide rail 21 from becoming a cantilever beam when the tray assembly 4 slides to the rear end of the slide rail 21, and to prevent the slide rail 21 from bending and deforming after long-term use.

[0049] Preferably, in this embodiment, the front end of the slide rail 21 is fixed to the first fixed base plate 11 in the base assembly 1, while the rear end of the slide rail 21 is supported on the original decorative panel 9 of the aircraft by the support block. The reason for this arrangement is that the original decorative panel 9 of the aircraft only has two sets of mounting holes for the support component at the front part of the decorative panel 9, and there are no mounting holes at the rear part of the decorative panel 9. The installation of the first fixed base plate 11 can be fixed by using the original mounting holes at the front part of the decorative panel 9. In this way, the entire modification project of the electronic flight bag fixing bracket will not damage the original structure of the decorative panel 9 and the original support component, which meets the airworthiness standards of the aircraft.

[0050] The connecting component 3 includes a stainless steel damping hinge seat disposed on the connecting plate 24. The hinge seat is connected to the connecting plate 24 at one end via a hinge assembly and to the tray assembly 4 at the other end. The hinge seat is limited to deflection of 0-30° by a limiting member, allowing the pilot to adjust the electronic flight bag screen on the fixed bracket to rotate freely within the range of 0-30° with one hand, stopping as needed, and adjusting the electronic flight bag to an angle suitable for the pilot's line of sight. The adjustment process is simple and convenient.

[0051] The tray assembly 4 includes a hollow card holder 41, with a slide 47 slidably disposed at the open end of the card holder 41. The slide 47 is inserted into the card holder 41 in a drawer-like manner. A first claw 42 is disposed at the blind end of the card holder 41, and a second claw 43 is disposed at the sliding end of the slide 47 corresponding to the first claw 42. The electronic flight bag is installed and locked between the first claw 42 and the second claw 43.

[0052] Furthermore, the slide 47 includes a guide slide rod 44 inserted into the mounting base 41. A second return spring (not shown) is sleeved on the guide slide rod 44. One end of the second return spring is fixed to the mounting base 41, and the other end is fixed to the slide 47, allowing the slide 47 to slide elastically within the mounting base 41. Under the action of the second return spring, the electronic flight bag is secured between the first claw 42 and the second claw 43. Guided by the guide slide rod 44, the slide 47 slides more smoothly and without jamming when pulled out of the mounting base 41, making it easier to operate.

[0053] Furthermore, a turntable 45 is provided at the bottom of the card holder 41. The turntable 45 is mounted on the hinge seat in the connecting assembly 3. The card holder 41 can rotate omnidirectionally on the turntable 45, allowing the pilot to freely adjust the attitude of the electronic flight bag to a comfortable angle.

[0054] Preferably, in this embodiment, the first claw 42 and the second claw 43 are both made of aluminum alloy, and flame-retardant foam is installed on the inner edges of the first claw 42 and the second claw 43. The flame-retardant foam not only avoids pinching the electronic flight bag, but also plays a role in shock absorption.

[0055] Preferably, in this embodiment, rubber blocks 46 are provided at both ends of the outer side of the first claw 42 and the second claw 43, so that the four corners of the entire tray assembly 4 are rubber blocks 46, which can effectively prevent the fixed bracket from scratching the sliding window glass of the aircraft in the event of failure of the limiting or locking.

[0056] In this embodiment, when the pilot installs the electronic flight bag, they only need to pull the slide 47 off the mounting bracket 41 with slight force by hand, and the electronic flight bag can be easily placed on the mounting bracket 41. Under the action of the second return spring, the electronic flight bag is clamped between the first claw 42 and the second claw 43. The tray assembly 4 in this embodiment can clamp electronic flight bags with a length of not less than 205 mm and not more than 280 mm, a width of not less than 170 mm and not more than 180 mm, a thickness of not less than 6 mm and not more than 8 mm, and a weight of not more than 0.8 kg, and is also compatible with electronic flight bags of different sizes.

[0067] S5: Install tray assembly 4 on connecting assembly 3.

[0068] Furthermore, in step S1, the original support of the decorative panel 9 is connected to the front of the decorative panel 9 through the rivet holes and rivets on the decorative panel 9. The rivet holes include a first set of rivet holes and a second set of rivet holes. In step S1, some of the rivets in the rivet holes of the decorative panel 9 are removed so that the original support of the decorative panel 9 remains connected to the decorative panel (9).

[0069] Furthermore, in step S2, the first fixing base plate 11 is installed on the top surface of the lower decorative panel 9 of the aircraft sliding window, and the second fixing base plate 12 and the third fixing base plate 13 are installed at intervals on the bottom surface of the lower decorative panel 9 of the aircraft sliding window.

[0070] Furthermore, in step S2, the first fixed base plate 11 has a first set of assembly holes and a second set of assembly holes at both ends, which correspond to the two sets of rivet holes on the decorative panel 9. The first set of assembly holes is used to connect and fix the first fixed base plate 11, the decorative panel 9, the second fixed base plate 12, and the original support of the decorative panel 9 in sequence by rivets. The second set of assembly holes is used to connect and fix the first fixed base plate 11, the decorative panel 9, the third fixed base plate 13, and the original support of the decorative panel 9 in sequence by rivets, so that the two ends of the first fixed base plate 11 are connected and fixed to the decorative panel 9 and the original support by the second fixed base plate 12 and the third fixed base plate 13, respectively.

[0071] Furthermore, in step S3, the front end of the slide rail 21 is screwed and fixed to the first fixed base plate 11. Specifically, the first fixed base plate 11 has a third set of assembly holes in the middle for screwing the slide rail 21.

[0072] Furthermore, in step S3, the rear end of the slide rail 21 is suspended and supported on the decorative panel 9 by a support block fixed to the rear end of the slide rail 21, with the bottom surface of the support block in contact with the top surface of the decorative panel 9.

[0073] Furthermore, in step S4, the hinge seat of the connecting assembly 3 is installed on the slider 23.

[0074] Furthermore, in step S5, the turntable 45 of the tray assembly 4 is mounted on the hinge seat in the connecting assembly 3.

[0075] Compared to existing technologies, the installation method of the portable electronic flight bag mounting bracket in this case involves installing the bracket on the original decorative panel of the aircraft without damaging the original decorative panel and its original supporting components. This does not affect the pilot's daily operations or the pilot's safe escape in special circumstances.

[0076] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
