Description

TECHNICAL FIELD

[0001] The present application relates to the field of aircraft interior installation design, and in particular to an aircraft luggage rack box door adjusting device which is not only used for the installation of an aircraft luggage rack, but also has the functions of box door fixing, box door limiting and attitude adjusting. BACKGROUND

[0002] As is known, in modern aircraft, an aircraft luggage rack is used for the placement of articles carried by passengers and part of the on-board emergency equipment. Figure 1 A structural schematic diagram of a typical aircraft luggage rack in the prior art is shown schematically. As shown in the diagram, the aircraft luggage rack mainly comprises a box body A and a box door B, wherein the box body A and the box door B are typically connected through a hinge device C and a screw D. Conventional aircraft luggage racks are generally divided into fixed type and pivot type. The fixed type is mainly used in branch or narrow-body aircraft, and the box body is used for the placement of luggage or equipment. The pivot type is used in large trunk or wide-body aircraft, and the box door is also used for the placement of luggage or equipment.

[0003] However, since the aircraft luggage rack belongs to functional equipment in the aircraft, passengers often need to open the box door before placing or taking the luggage or equipment. This involves the problem of the usability of the aircraft luggage rack, that is, the height after the box door is opened and the angle of the box door opening, which both affect each other and have a key impact on the convenience of passengers placing or taking luggage or equipment on the route. This is because: if the box door is opened at a higher distance from the floor of the aircraft, it will directly affect the convenience of the aisle passengers, and therefore the opening angle of the box door is usually designed to be adjustable so as to be able to adjust the height after the box door is opened.

[0004] At present, there are mainly the following schemes in this technical field:

[0005] For example, the existing document US6622965B1 relates to an aircraft luggage rack composed of a limiting wall with a partition and a cover and a cover opening mechanism. The cover opening mechanism comprises a gas compensator and an arm, one end of which is fixed to the partition through a hinge pin, and the other end is fixed to the luggage rack cover through a bracket. A roller is fixed to the arm in such a way that it can move along the shaped guide formed in the partition. In addition, there is a housing on the top of the rack, and in the housing, the cover is arranged at the topmost position.

[0006] For example, the existing document CN209427040U relates to an aircraft cabin luggage rack hatch cover lock control device, which comprises an electromagnetic lock, a connection circuit, a magnetic steel plate, a remote control and a line controller. During the ground sliding of the aircraft (including before take-off and after landing), the remote control is used to lock the luggage rack hatch cover, so that the passenger cannot open the luggage rack hatch cover to take luggage, thereby avoiding accidental injury to the passenger.

[0007] In fact, the adjustment on the current route is mainly achieved by adjusting the fixed position of the hinge device for connecting the box body and the box door, but this adjustment must be performed after releasing the screw for fixing the hinge, which not only seriously affects the production and assembly efficiency of the manufacturer, increases the development cost, but also greatly affects the operation efficiency of the aircraft operator and the route operation, increases the maintenance and use cost, and directly affects the economic benefit.

The support structure 1 is the base unit of the aircraft luggage rack door adjustment device of the application, and the limiting mechanism 2 and the latch mechanism 3 are both installed on the support structure 1.

[0058] The composition of the aircraft luggage rack door adjustment device of the application and the functions of the main components will be described in detail below.

[0059] Support structure 1

[0060] Figure 3 A schematic structural diagram of the support structure in the aircraft luggage rack door adjustment device of the application is shown. The left side shows the back of the support structure, and the right side shows the front of the support structure. Figure 3 The left side shows the back of the support structure, and the right side shows the front of the support structure. Figure 3 The left side shows the back of the support structure, and the right side shows the front of the support structure.

[0061] As shown, the support structure 1 is preferably in the shape of "L" (but not limited to this), and is composed of a first end 1A and a second end 1B, wherein the first end 1A is the short side of the "L" shape, and the second end 1B is the long side of the "L" shape.

[0062] A first clamping groove 11 is arranged on the first end 1A of the support structure 1. The limiting mechanism 2 is connected with the first clamping groove 1A so as to provide the limiting mechanism 2 with a moving space by the support structure 1.

[0063] A second clamping groove 12 is arranged on the second end 1B of the support structure 1. The locking mechanism 3 is connected with the second clamping groove 1B so as to provide the locking mechanism 3 with a moving space by the support structure 1.

[0064] The limiting mechanism 2 and the locking mechanism 3 are respectively installed on the support structure 1 through the first clamping groove 11 and the second clamping groove 12.

[0065] In addition, a limiting adjuster opening 13 is arranged at the bottom of the first clamping groove 11, and a locking adjuster opening 14 is arranged at the bottom of the second clamping groove 12, which are used for adjusting the opening and closing postures of the luggage rack door.

[0066] Limiting mechanism 2

[0067] Figure 4 The structure of the limiting mechanism in the adjusting device for the door of the luggage rack of the aircraft of the present application is schematically shown. The limiting mechanism 2 is used to control the opening posture of the door of the luggage rack of the aircraft.

[0068] As shown in the figure, the limiting mechanism 2 mainly comprises a limiting adjuster 21 and a limiting adjuster 22, and the limiting adjuster 21 is connected with the limiting adjuster 22. Preferably, one end of the limiting adjuster 22 is threadedly connected with the limiting adjuster 21.

[0069] In order to prevent the limiting adjuster 22 from rotating, the limiting mechanism 2 is further provided with an adjuster fixing device 23, which is a sleeve structure and provides support for the fixing of the limiting adjuster 22 in the first clamping groove of the support structure 1. Preferably, the support allows the limiting adjuster 22 to be rotated and adjusted through the limiting adjuster opening 13 at the bottom of the first clamping groove 11.

[0070] Figure 5 The operation of the limiting mechanism in the adjusting device for the door of the luggage rack of the aircraft of the present application is schematically shown.

[0071] As shown in the figure, during the installation of the limiting mechanism 2 in the support structure 1, when the limiting adjuster 21 is rotated through the limiting adjuster opening 13 by using an adjusting tool 100, the limiting adjuster 21 will move in the direction of the arrow R relative to the support structure 1, thereby achieving the adjustment of the opening angle of the door of the luggage rack. Preferably, the adjusting tool can be a common hexagonal tool.

[0072] Latching mechanism 3

[0073] Figure 6The structure diagram of the latch mechanism in the aircraft luggage rack door adjusting device is shown schematically. The latch mechanism 3 is used to control the closing position of the aircraft luggage rack door.

[0075] Figure 7 The operation diagram of the latch mechanism in the aircraft luggage rack door adjusting device is shown schematically.

[0076] As shown in the figure, before adjusting the latch 31, the latch 31 is manually pushed in the direction of the arrow R2 to expose the latch adjuster 34, which facilitates the operation of the adjusting tool 100. Then, the latch mechanism 3 is installed in the support structure 1. When the adjusting tool 100 is rotated through the latch adjusting port 14, the latch mounting unit 33 moves in the direction of the arrow R2 relative to the support structure 1, and the movement is transmitted to the latch 31 through the latch connecting rod 32, thereby adjusting the closing position of the luggage rack door.

[0077] In summary, in the aircraft luggage rack door adjusting device of the present application, the limiting mechanism provides the limiting function after the door is fully opened, and the latch mechanism provides the function of fixing the door lock hook. Therefore, when it is necessary to adjust the angle of the fully opened luggage rack door, it is only necessary to use a common adjusting tool, such as a hexagonal tool, to rotate the limiter and the latch fixing point to achieve the adjustment.

[0078] In view of the above technical solution, compared with the prior art, the aircraft luggage rack door adjusting device of the present application can not only provide the limiting of the door rotation, but also conveniently adjust the door without the need to remove the relevant fasteners or parts. Moreover, since the aircraft luggage rack door adjusting device of the present application has the functions of part integration and convenient adjustment, it can not only improve the production and assembly efficiency of aircraft manufacturers and reduce the development cost, but also improve the operation efficiency for aircraft operators and airlines, thereby greatly improving the economic benefits, and also better product maintenance and use convenience.
