Description

Technical Field

[0001] This utility model relates to the field of aircraft cabin storage technology, and specifically to a cabin storage cabinet. Background Technology

[0002] To meet the stringent requirements of civil aviation airworthiness regulations regarding strength, rigidity, and occupant survival rate (crash resistance) under emergency landing conditions, traditional aircraft cabin storage compartments, luggage compartments, and other devices generally use metal materials and conservative structural designs.

[0003] This design philosophy is essentially "trading weight for safety": to ensure the structure is foolproof, designers often tend to use additive methods such as continuously increasing the thickness of sheet metal parts and adding dense reinforcing ribs and supporting components to cope with extreme loads. This approach directly results in the high structural weight of storage devices.

[0004] However, in the aviation industry, weight is a core indicator related to fuel economy and operational efficiency. Excessive cabin interior equipment, especially numerous overhead storage compartments, significantly increases the aircraft's unproductive weight. According to industry consensus, every kilogram of weight reduction can save tens of thousands of dollars in fuel costs over an aircraft's lifespan. Therefore, the "overweight" problem of traditional metal storage structures directly translates into high operating costs for airlines, weakening their market competitiveness.

[0005] Currently, lightweighting has become one of the primary principles of aircraft design, and the application of new materials and new structural forms is the main trend. However, how to achieve significant weight reduction in these new solutions with more sophisticated and efficient designs while meeting or even exceeding established airworthiness standards remains a technical challenge that the industry urgently needs to overcome.

[0024] Example

[0025] See Figure 1 , Figure 2 and Figure 3 This embodiment discloses a cabin storage cabinet, including a side panel 10, a door panel 20, a support rod 30, and a support plate 40. There are two side panels 10, arranged parallel to each other, with a gap between them forming a storage area for storing items on the aircraft. Sealing panels 50 are installed at the top, bottom, and back of the storage area.

[0026] All side plates 10 are fixedly connected to all end plates 50 by multiple connecting parts, including but not limited to multiple screws and multiple L-shaped metal connecting plates, and the metal connecting plates are provided with through holes through which the screws pass.

[0027] One side of the door panel 20 is rotatably connected to the side of a side panel 10 via a hinge. Usually, multiple hinges are installed to achieve the rotatable connection. The other side of the door panel 20 is detachably connected to another side panel 10. Usually, a door lock is installed between the door panel 20 and the side panel 10 to achieve the detachable connection. In addition, the door panel 20 is installed at the front of the storage area.

[0028] The support rod 30 is set at the top of the storage area, and both ends of the support rod 30 are connected to the two side plates 10 respectively, so that the eye of the support rod 30 is installed horizontally in the storage area.

[0029] The support plate 40 is installed at the bottom of the storage area, and both sides of the support plate 40 are also fixedly connected to the two side plates 10 respectively.

[0030] The side panel 10 located at the back of the storage area has an arc-shaped edge, and the distance between the left and right sides of the storage area is smaller than the distance between its front and rear sides. This design allows for installation inside the aircraft cabin.

[0031] The locker in this technical solution consists of only two side panels 10, one door panel 20, one support plate 40, and a support rod 30, plus connecting parts. It not only has strong structural stability, but also has the advantage of being lighter than existing technologies, which is more conducive to the use of civil aircraft.

[0032] In addition, the entire locker is equipped with an aluminum alloy frame, and the aforementioned side panels 10, door panels 20, sealing panels 50, and support panels 40 are all supported by fiber-reinforced composite material (aramid fiber) sandwich panels. This further reduces the overall weight of the locker.

[0033] In one specific embodiment: The storage area is equipped with two support rods 30 at the same height, distributed along the front-to-back direction of the storage area. By installing multiple support rods 30, more items can be hung above the storage cabinet.

[0034] In another specific embodiment: The side panel 10 has a curved edge with a cushioning strip 60. When installing the storage cabinet, the cushioning strip 60 is connected to the internal structure of the aircraft cabin.

[0035] By installing the cushioning strip 60, vibrations during flight can be absorbed, thereby protecting the integrity of the locker structure and enhancing its shock resistance.

[0036] In another specific embodiment: The support panel 40 divides the storage area into an upper hanging space and a lower storage space, with the hanging space being 2-4 times the height of the storage space. The ample hanging space allows for the hanging of frequently used items such as towels, blankets, and clothing. The storage space can hold smaller, miscellaneous items.

[0037] In another specific embodiment: One of the side panels 10 is the outer side panel 11, which has a straight structure. The other side panel 10 is the inner side panel 12, which has a Z-shaped structure.

[0038] Specifically, the inner panel 12 includes a first panel 121, a second panel 122, and a third panel 123. The first panel 121 and the third panel 123 are arranged parallel to each other, and the two sides of the second panel 122 are perpendicularly connected to the first panel 121 and the third panel 123, respectively. The storage area is located between the first panel 121 and the outer panel 11, and the area between the third panel 123 and the outer panel 11 is a support area. A back panel is provided between the storage area and the support area.

[0039] This design allows for adaptation to the cabin's spatial structure and provides a large support area for the storage locker's installation within the cabin, thereby enhancing its stability during flight.

[0040] In another specific embodiment, multiple ribs are provided on the side plate 10 and between the two side plates 10, thereby enhancing the impact resistance of a single side plate 10.

[0041] In another specific embodiment: The top panel 50 of the storage area has a curved front end and extends downwards from the front of the storage area to the top of the door panel 20. By designing the top panel 50 of the storage area to be curved forward, the exposed parts of the entire storage cabinet are protected from right angles, thus providing good protection and preventing injury to passengers or crew members during aircraft turbulence.

[0042] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
