Description

Technical Field

[0001] This utility model relates to the field of aircraft cabin crew accessories, and in particular to a fireproof and flame-retardant luggage box for civil aviation passenger aircraft flight crew members. Background Technology

[0002] The cabin crew's suitcases are not only storage containers for their belongings, but also "mobile equipment depots" to ensure the smooth execution of flight missions and respond to various emergencies. For the needs of civil aviation operations, suitcases are permitted to store communication and electronic devices (such as work mobile phones, spare power banks, and emergency lighting tools, etc., provided they meet civil aviation regulations. Work mobile phones are used for internal crew communication or receiving airline notifications; spare power banks must comply with civil aviation regulations, and the rated energy value of lithium-ion batteries must not exceed 100Wh; those exceeding 100Wh but not exceeding 160Wh require airline approval). Electronic devices containing lithium batteries also include laptops, electronic flight bags (EFB), flashlights, Bluetooth headsets, etc. If electronic devices containing lithium batteries are placed in the aircraft cockpit, they pose a potential threat to flight safety. Work phones and spare power banks, among other electronic devices, contain lithium batteries. Lithium batteries can experience thermal runaway due to internal short circuits, overcharging, or physical damage. This uncontrolled chemical reaction within the battery releases large amounts of heat and flammable gases (such as carbon monoxide and hydrogen fluoride), potentially causing a fire and posing a significant risk. This places higher demands on the luggage of flight crew members, as existing ordinary luggage simply cannot meet fire-retardant requirements. Luggage is an essential item for flight crew members, and both crew members and luggage remain on the aircraft for extended periods during their work. Although mobile phones and spare power banks meet civil aviation regulations, they still represent potential sources of incident risk and are a key focus for airlines in lithium battery protection. Therefore, luggage safety measures are becoming increasingly important. Utility Model Content

[0006] Preferably, the intermediate heat insulation layer is further composited with a multi-layer reflective heat insulation screen, which is composed of alternating layers of high-reflectivity metal foil and low-thermal-conductivity spacer material; the intermediate heat insulation layer is also filled with an inorganic heat-absorbing material, which includes one or more of magnesium hydroxide, aluminum hydroxide, hydrated potassium aluminum sulfate, and hydrated calcium sulfate.

[0007] Preferably, the high-temperature resistant inner lining is further filled with titanium alloy foil and / or stainless steel foil, and the flame-retardant fiber fabric is made of one or more composites of aramid and polyimide.

[0011] Preferably, the housing is rectangular in shape, and corner reinforcement structures are provided at the corners of the top and / or bottom of the housing; an elastic sealing strip is provided between the outer sealing plate of the top cover and the inner lining plate of the housing, and the elastic sealing strip is made of silicone rubber, fluororubber or expanded graphite woven tape.

[0012] Preferably, the top cover plate and / or the housing body have a pressure relief port, and a pressure relief flame arrester is installed at the pressure relief port by means of an elastic sealing strip. The pressure relief flame arrester includes a turbine interceptor cylinder and an exhaust cover plate that is sealed to the turbine interceptor cylinder. The turbine interceptor cylinder has an interceptor cylinder cavity for intercepting particles.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects: (1) This utility model is specifically designed for fireproof and flame-retardant luggage that is frequently used by flight crew members for extended periods of time. The fireproof and flame-retardant luggage can store lithium battery-containing electronic devices in accordance with regulations. The whole is composed of a lightweight internal frame and a multi-layer fireproof composite structure tightly wrapped around the lightweight internal frame. The multi-layer fireproof composite structure includes a high-temperature resistant inner lining, a middle heat insulation layer and an impact-resistant heat insulation layer from the inside to the outside.

It has the advantages of high structural performance and strong safety protection capabilities.

[0015] (2) This utility model is equipped with a pressure relief flame arrester through a sealing fit of an elastic sealing strip. When the thermal runaway of the lithium battery causes high temperature and high pressure airflow (including smoke or dust generated by combustion) to enter the turbine interceptor cylinder through the air inlet, the smoke, dust or particulate matter (such as battery fragments and larger particulate matter spray) is intercepted inside the interceptor cylinder cavity. The intercepted gas is discharged through the air outlet of the air outlet cover and pressure relief is performed, effectively releasing the high pressure gas containing the box to prevent the suitcase from being damaged.

[0016] (3) The lightweight built-in frame of this utility model serves as the inner lining support structure of the housing, ensuring the integrity of the housing structure, preventing deformation and cracking under high temperature and high pressure; the multi-layer fireproof composite structure has the advantages of good heat insulation and protection effect and good airflow impact resistance, which improves the protection capability of the lithium battery thermal runaway inside the fireproof and flame-retardant luggage.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the embodiments: Example

[0020] like Figures 1 to 7As shown, a fire-resistant and flame-retardant luggage case for civil aviation passenger aircraft flight crew includes a housing body 1 and a lid assembly hinged to the housing body 1. The housing body 1 has an opening at the top, and the interior of the housing body 1 is an inner cavity 2 communicating with the opening. The edge of the opening of the housing body 1 extends with an inner lining 3 (such as...). Figure 3 As shown, the inner side of the opening edge of the accommodating box 1 has a raised inner lining plate 3. The inner lining plate 3 forms a step at the opening to facilitate the sealing of the outer sealing plate 81 of the top cover plate 8. The box cover assembly includes a top cover plate 8, the edge of which has an outer sealing plate 81 that seals against the inner and outer sides of the inner lining plate 3. The top cover plate 8 seals the opening of the accommodating box 1 (when the top cover plate 8 is on top of the accommodating box 1, the outer sealing plate 81 is tightly fitted against the outer side of the inner lining plate 3, and the top cover plate 8 completely covers and seals the opening of the accommodating box 1). An elastic sealing strip is installed between the outer sealing plate 81 and the inner lining plate 3 to enhance the sealing performance. This embodiment of the fireproof and flame-retardant luggage clearly marks safety warnings such as "Fireproof luggage - specially designed for lithium battery-containing equipment" and "Do not move in case of fire"; it can also integrate a temperature indicator label (thermal label).

[0021] like Figure 6 As shown, the housing 1 consists of a lightweight internal frame 12 and a multi-layer fireproof composite structure 13 tightly wrapped around the lightweight internal frame 12. Preferably, the lightweight internal frame 12 is located in the middle of the multi-layer fireproof composite structure 13 (see [reference]). Figure 6The lightweight internal frame 12 serves as the internal support layer for the housing 1. In this embodiment, the housing 1 is rectangular in shape, with four edges on its top and bottom surfaces and four edges on its sides. All edges are connected to form a rectangular frame structure. The lightweight internal frame 12 includes edge structures made of lightweight titanium alloy or aluminum alloy. These edge structures constitute the edges of the housing 1, and all edge structures are connected to form a rectangular frame structure. Preferably, the lightweight internal frame 12 also includes connecting reinforcing ribs. Several connecting reinforcing ribs are correspondingly connected to the rectangular frame structure (generally in the bottom and side areas of the housing 1, or in areas prone to collapse, such as areas with a large side surface; the use of connecting reinforcing ribs effectively improves the side support capacity; the multi-layer fireproof composite structure 13 covering the exterior of the lightweight internal frame 12 has good planar effect and anti-collapse function) to improve the overall structural performance of the housing 1. The lightweight internal frame 12 serves as the inner lining support structure for the suitcase 1, providing a cavity structure that is non-deformable and stable for the inner cavity 2. If the lithium battery inside the suitcase experiences thermal runaway, it will not be damaged by structural damage (such as collapse or disintegration) and thus fail to provide protection (when the lithium battery experiences thermal runaway, the high pressure and high heat environment inside the suitcase 2 will place higher demands on the structural performance of the suitcase 1). In this embodiment, the lightweight internal frame 12 can ensure the structural integrity of the suitcase 1 under high temperature and high pressure, without deformation or cracking.

[0022] like Figure 7 As shown, the multi-layer fireproof composite structure 13 includes, from the inside out, a high-temperature resistant inner lining 133, an intermediate heat insulation layer 132, and an impact-resistant heat insulation layer 131. The high-temperature resistant inner lining 133 is made of flame-retardant fiber fabric (such as aramid, polyimide, etc.) and / or ceramic fiber fabric (such as Nextel, alumina fiber cloth) that can withstand temperatures greater than 900°C. The high-temperature resistant inner lining 133 does not melt, does not support combustion, and produces low smoke at extreme high temperatures. Preferably, the high-temperature resistant inner lining 133 is also filled with titanium alloy foil and / or stainless steel foil, and the flame-retardant fiber fabric is made of one or more composites of aramid and polyimide.

[0023] The intermediate heat insulation layer 132 is made of one or more composites of aerogel felt, intumescent fireproof material, and ceramic fiber material. In this embodiment, the heat insulation layer 132 is composed of aerogel felt, intumescent fireproof material with a temperature resistance greater than 1000°C, and ceramic fiber material with a temperature resistance greater than 1260°C in sequence. The aerogel felt (such as silica aerogel) has an extremely low thermal conductivity (<0.02 W / mK) and can provide excellent heat insulation effect with its ultra-thin thickness, effectively blocking heat transfer to the outside. The intumescent fireproof material (such as intumescent fireproof gypsum board, fireproof sealing board, etc.) undergoes a chemical reaction when heated, expanding its volume by tens or even hundreds of times, and forming a dense, low thermal conductivity intumescent char layer. The ceramic fiber material uses low thermal conductivity and chemically stable ceramic fibers, which have excellent heat insulation and fire resistance properties. Preferably, the intermediate heat insulation layer 132 is further composited with a multi-layer reflective heat insulation screen. The multi-layer reflective heat insulation screen is composed of alternating layers of high-reflectivity metal foil (e.g., aluminum foil) and low-thermal-conductivity spacer material. For example, several layers of aluminum foil are sequentially composited with low-thermal-conductivity spacer material. The multi-layer reflective heat insulation screen provides insulation by reflecting radiant heat. The intermediate heat insulation layer 132 is also filled with an inorganic heat-absorbing material, including one or more of magnesium hydroxide, aluminum hydroxide, hydrated potassium aluminum sulfate, and hydrated calcium sulfate. When heated, the inorganic heat-absorbing material absorbs heat and produces water, thus interrupting the combustion chain reaction and providing physical cooling.

[0024] The impact-resistant thermal insulation layer 131 is composed of one or more composites of fire-retardant carbon fiber reinforced polymer, Kevlar fiber reinforced polymer, and aramid / high-strength polyester substrate; the impact-resistant thermal insulation layer 131 mainly provides physical protection for structural strength and internal and external thermal insulation to resist external impact and internal pressure.

[0025] In some preferred embodiments, the high-temperature resistant inner lining 133 of the multi-layer fireproof composite structure 13 (with high resistance to extreme high temperatures, high specific heat capacity or heat of vaporization, high carbonization rate, and excellent thermal stability) is made of one or more of the following: PBO fabric (poly(p-phenylene benzodioxazole) fiber), polyimide PI fabric, high-silica fiber fabric, carbon fiber fabric, basalt fiber fabric, and aramid pre-oxidized fiber blend / aramid pre-oxidized fiber coated with aluminum foil. The intermediate heat insulation layer 132 is made of one or more of the following: pre-oxidized fiber heat insulation felt, Nomex needle-punched felt (aramid heat insulation felt), carbon fiber & aramid blend heat-resistant and flame-retardant felt, ceramic fiber felt, and aerogel felt. The impact-resistant heat insulation layer 131 (with high strength, high modulus, and excellent abrasion and tear resistance) is made of one or more of the following: aramid fabric, carbon fiber & aramid blended fabric, PBO fabric, and polyimide PI fabric.

[0026] In some embodiments, such as Figures 1-3As shown, the bottom front of the housing 1 is equipped with several unidirectional rotating ratchet guide wheels 6 (made of high-temperature resistant wheel materials, such as high-performance polymers or metal coatings). In this embodiment, the ratchet guide wheels 6 restrict movement to only forward and cannot move backward. The bottom rear of the housing 1 is equipped with several feet 7. (As shown...) Figure 2 As shown, a pull rod assembly 4 is installed on one side of the housing 1. The pull rod assembly 4 includes two pull rod cylinders and a pull rod that moves up and down within the pull rod cylinders. A pull rod handle 41 is connected and fixed to the top of the pull rod. The housing cover assembly also includes flip-up plates 9 hinged to three outer sealing plates 81 on the top cover 8. The three outer sealing plates 81 correspond to the three sides of the non-pull rod assembly 4 (i.e., the three sides of the non-pull rod assembly 4 each have an outer sealing plate 81, see [reference]). Figure 2 The side panel 9 is locked to the housing 1 by a combination lock 10. The combination lock 10 is made of high-temperature resistant metal (stainless steel, titanium alloy) and must maintain its locking function at high temperatures to prevent the top cover 8 from accidentally popping open due to internal pressure or deformation. Preferably, the top cover 8 of the housing cover assembly is also composed of a lightweight internal frame 12 and a multi-layer fireproof composite structure 13 tightly wrapped around the lightweight internal frame 12. A handle 82 is fixed to the outer side of the top cover 8.

[0027] In some embodiments, such as Figure 3 As shown, the housing 1 is generally rectangular in shape. Corner reinforcement structures 5 are provided at the top and / or bottom corners of the housing 1, which serve to strengthen the structure at the corners. An elastic sealing strip is provided between the outer sealing plate 81 of the top cover plate 8 and the inner lining plate 3 of the housing 1. The elastic sealing strip is made of silicone rubber, fluororubber, or expanded graphite woven tape.

[0028] like Figure 1As shown, a pressure relief port is provided on the top cover plate 8 and / or the housing 1. A pressure relief flame arrester 11 is installed at the pressure relief port through an elastic sealing strip. The pressure relief flame arrester 11 includes a turbine interceptor cylinder 111 and an exhaust cover plate 114 that is sealed and fitted onto the turbine interceptor cylinder 111. The turbine interceptor cylinder 111 has an interceptor cylinder cavity for intercepting dust, smoke, or particulate matter. The bottom of the interceptor cylinder cavity of the turbine interceptor cylinder 111 is a cylinder bottom plate. An air inlet 112 is provided in the center of the cylinder bottom plate (a one-way air pressure valve can be installed in the air inlet 112. The one-way air pressure valve has a preset pressure relief threshold. When the pressure in the inner cavity 2 of the housing is greater than the pressure relief threshold, the one-way air pressure valve opens the air inlet 112 and releases the pressure and exhausts the air. An example of the pressure relief threshold is 5-15 kPa). Several exhaust holes 115 communicating with the interceptor cylinder cavity are provided on the exhaust cover plate 114. Thermal runaway of lithium batteries or lithium battery-containing electronic devices causes high-temperature and high-pressure airflow (including smoke or dust generated by combustion) to enter the turbine interceptor cylinder 111 through the air inlet 112. Smoke, dust, or particulate matter (such as battery fragments and larger particulate matter spray) is intercepted inside the interceptor cylinder cavity. The intercepted gas is discharged through the air outlet 115 of the air outlet cover 114 and pressure is released.

[0029] In some embodiments, such as Figure 5 As shown, a turbine blade assembly located within the interception chamber is fixed to the bottom plate of the turbine interception cylinder 111. The turbine blade assembly consists of several turbine arc-shaped blades 113, all of which are circumferentially distributed around the air inlet 112. The turbine arc-shaped blades 113 are generally arc-shaped, with a height equal to half the height of the inner cavity of the turbine interception cylinder 111. All turbine arc-shaped blades 113 have the same arc orientation and are used to guide clockwise or counterclockwise airflow. Adsorbents, including activated carbon (which adsorbs some toxic gases such as HF and CO) and zeolite, are provided at the bottom of the interception chamber and / or on the walls of the interception chamber of the turbine interception cylinder 111. After the high-temperature and high-pressure airflow enters the turbine interceptor cylinder 111, the high-temperature and high-pressure airflow (carrying dust or particulate matter) is first blocked and intercepted by the various turbine arc blades 113 (after being intercepted, it will be gradually carried by the airflow to the bottom of the turbine interceptor cylinder 111 and accumulate). Then, under the guidance of the turbine blade assembly, it accumulates at the bottom of the interceptor cylinder cavity of the turbine interceptor cylinder 111. At the same time, under the centrifugal effect of the airflow, the dust or particulate matter will gradually be deposited on the circumference of the bottom of the interceptor cylinder cavity of the turbine interceptor cylinder 111, and can be cleaned up afterward.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
