Description

Technical Field

[0001] This utility model relates to the field of aviation protective box technology, and in particular to an aviation safety protective box. Background Technology

[0002] With the improvement of people's living standards, the penetration rate of electronic products is increasing. Electronic devices containing lithium batteries, such as mobile phones and laptops, have become necessities and are inseparable from people's lives. Even when traveling by plane, almost every passenger carries these electronic products. Lithium batteries have the risk of spontaneous combustion and explosion, and this is highly unpredictable. The large number of electronic products containing lithium batteries in aircraft cabins poses a significant threat to aviation safety. Once a lithium battery fire occurs in an aircraft cabin, if it is not dealt with promptly and effectively, it will inevitably lead to loss of life, property damage, or environmental damage.

[0003] In related technologies, equipment for emergency response to lithium battery fires and smoke in the cabin, such as fireproof bags, are similar to tablet bags—lightweight, compact, and easy to use. However, they cannot handle the large amounts of toxic gases and dust particles generated during a lithium battery fire and smoke process, nor do they have explosion-proof capabilities. Fireproof bags are small and have limited space, making them unsuitable for handling larger, common equipment. Furthermore, the soft material of fireproof bags is not ideal for storing unburned lithium batteries. Previously reported emergency response boxes also focus on emergency response after a lithium battery fire, with less consideration for storage requirements and relatively limited storage space. This makes storing and handling lithium batteries inconvenient, hindering emergency response to lithium battery fires and thus reducing the protective effect of lithium batteries.

[0004] Therefore, it is necessary to provide an aviation safety protection case to solve the above problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 5 An aviation safety protection case includes: a case body 1, with a case cover 2 hinged to the top of the case body 1;

[0025] Both the box body 1 and the box lid 2 are composed of a five-layer structure, including an outer layer 101, a first intermediate layer 102, a second intermediate layer 103, a third intermediate layer 104 and an inner layer 105. The outer layer 101 is a carbon fiber protective layer, the first intermediate layer 102 is a high-performance non-combustible cloth, the second intermediate layer 103 is a flame-retardant heat insulation felt, the third intermediate layer 104 is a high-performance non-combustible cloth, and the inner layer 105 is an aluminum alloy inner liner.

[0026] Multiple U-shaped frames 3 are fixedly installed on the inner walls of the box body 1 and the box cover 2 respectively. Each U-shaped frame 3 has a self-extinguishing patch 4 glued inside, and each U-shaped frame 3 has a sliding clamp 5 located on both sides of the self-extinguishing patch 4.

[0027] Multiple drive components 6 are respectively disposed on one side of multiple U-shaped frames 3, and are used to drive the movement of the clamping plates 5 inside them.

[0028] In this embodiment, both the housing 1 and the lid 2 are composed of a five-layer structure, using independently developed high-performance composite materials, non-combustible materials, and high-strength materials to form a sandwich design. This achieves high strength, lightweight, and corrosion resistance for the housing 1, with a long-term temperature resistance of 1500℃, significantly improving its explosion-proof and flame-retardant performance. Furthermore, the overall weight of the housing 1 does not exceed 5.5 kg, achieving a lightweight design while ensuring explosion-proof and flame-retardant functions, making it convenient to carry and use. The housing 1 and lid 2 are equipped with independently developed self-extinguishing fire patches 4 around their perimeter, enabling active sensing and autonomous fire extinguishing. Moreover, the movement of the clamping plate 5 is driven by the drive component 6, facilitating the stable installation of the self-extinguishing fire patches 4 and preventing them from sliding and falling off, which would result in poor fire extinguishing effect. This facilitates efficient protection of the lithium battery and improves its protective effect.

[0029] In a further embodiment, such as Figure 3 As shown, the drive assembly 6 includes two fixing blocks 61, both of which are fixedly mounted on one side of the U-shaped frame 3. A bidirectional lead screw 62 is rotatably connected between the two fixing blocks 61. Two drive blocks 63 that are fixed to the clamping plate 5 are threadedly connected to the outer wall of the bidirectional lead screw 62. A handle 64 is fixed to one end of the bidirectional lead screw 62.

[0030] In this embodiment, after the self-extinguishing patch 4 is adhered to the U-shaped frame 3, the handle 64 is manually rotated. The handle 64 drives the bidirectional lead screw 62 to rotate, and the bidirectional lead screw 62 drives the two drive blocks 63 to move in opposite directions. The two drive blocks 63 can then drive the two clamping plates 5 to move in opposite directions. In this way, the self-extinguishing patch 4 can be clamped and fixed by the two clamping plates 5, which facilitates the stable installation of the self-extinguishing patch 4 and prevents the self-extinguishing patch 4 from falling off during adhesion, thereby facilitating the use of the self-extinguishing patch 4.

[0031] In a further embodiment, such as Figure 3 As shown, it also includes a sliding component 7, which includes two first sliders 71. The two first sliders 71 are fixedly disposed on both sides of the clamping plate 5. The inner walls of the U-shaped frame 3 are provided with first sliding grooves 72 on both sides. The two first sliders 71 are slidably connected to the two first sliding grooves 72 respectively.

[0032] In this embodiment, when the clamping plate 5 moves, it drives the first slider 71 to slide within the first slide groove 72. In this way, the sliding cooperation between the first slider 71 and the first slide groove 72 facilitates the auxiliary support and limiting of the clamping plate 5, and makes it easier for the clamping plate 5 to move stably.

[0033] In a further embodiment, such as Figure 2As shown, a groove 8 is provided in the middle of the top of the box cover 2, and a handle 9 is rotatably connected in the groove 8. A filter port 10 is provided on one side of the top of the box cover 2, and a viewing window 11 is provided on the other side of the top of the box cover 2. A water inlet 12 is connected to the top of the box cover 2, and a cover plate 13 is provided at the top of the water inlet 12. An elastic component 14 for driving the cover plate 13 to move is provided at the top of the box cover 2.

[0034] In this embodiment, the handle 9, which can be made of stainless steel, facilitates the transfer of the box 1. The lid 2 and the box 1 are connected and locked by a butterfly buckle. The filter port 10 allows for the filtration of toxic gases and fumes. The visualization window 11 allows for easy observation of the situation inside the box 1. The water inlet 12 is used to inject fire extinguishing or cooling media into the box 1. The water inlet 12 can be quickly opened and closed by the movement of the cover plate 13 driven by the elastic component 14, thus facilitating the injection of fire extinguishing or cooling media.

[0035] In a further embodiment, such as Figure 5 As shown, the elastic component 14 includes a movable block 141, which is fixedly disposed on one side of the cover plate 13. A second slider 142 is fixed at the bottom end of the movable block 141. A second groove 143 for sliding the second slider 142 is provided at the top end of the box cover 2. The second groove 143 is elastically connected to the second slider 142 by a spring 144.

[0036] In this embodiment, under the elastic action of the spring 144, the second slider 142 is driven to move elastically, and the second slider 142 drives the moving block 141 to move elastically, thereby driving the cover plate 13 to move elastically. This facilitates the automatic closing of the cover plate 13, thereby facilitating the closing of the water inlet 12. When it needs to be opened, the personnel can manually move the cover plate 13.

[0037] In a further embodiment, such as Figure 1 As shown, a filter element 15 is fixed to the inner wall of the box cover 2, and the filter element 15 is set in correspondence with the filter port 10.

[0038] In this embodiment, the combination of filter port 10 and filter element 15 facilitates the discharge of toxic gases and fumes, and the filter element 15 can filter the toxic gases and fumes, preventing them from being directly discharged to the outside and causing pollution.

[0039] The working principle of the aviation safety protection box provided by this utility model is as follows:

[0040] After the self-extinguishing patch 4 is adhered to the U-shaped frame 3, the handle 64 is manually turned. The handle 64 drives the bidirectional lead screw 62 to rotate, which in turn drives the two drive blocks 63 to move in opposite directions. The two drive blocks 63 then drive the two clamping plates 5 to move in opposite directions. This clamping plate 5 secures the self-extinguishing patch 4, ensuring stable installation and preventing it from falling off during adhesion. This facilitates the use of the self-extinguishing patch 4. Then, the lithium battery is placed in the housing. Inside box 1, cover box 2 and lock it in place with butterfly buckles. With the cooperation of box 1 and box 2, using self-developed high-performance composite materials, non-combustible materials and high-strength materials, a sandwich design is formed, which makes box 1 high-strength, lightweight, corrosion-resistant and long-term temperature resistant to 1500℃, greatly improving explosion-proof and flame-retardant performance. In addition, through the self-developed self-extinguishing fire patch 4, it can realize the function of active sensing and self-extinguishing fire, thus facilitating efficient protection of lithium batteries and improving the protection effect of lithium batteries.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
