Abstract
Description
Technology Field
[0001] The present invention relates to a portable storage case for an auxiliary battery, and more specifically, to a portable storage case that not only prevents the spread of fire when a fire occurs in the auxiliary battery but also allows the auxiliary battery to be easily carried and moved. Background Technology
[0002] Lithium-ion batteries possess high energy density and are widely used in various electronic devices and industrial products, such as smartphones, laptops, electric vehicles, and energy storage systems (ESS). However, lithium-ion batteries are susceptible to thermal runaway caused by factors such as impact, short circuits, and overheating, which poses a risk of fire and explosion. Currently, various technologies are being researched to prevent battery fires or block their spread, leading to the development of protection circuits, heat dissipation systems, and fire extinguishing devices. Nevertheless, research on protective devices capable of effectively blocking battery fires during transit remains insufficient. In particular, if a battery fire occurs in aircraft, vehicles, trains, or personal portable devices, immediate response is difficult, and there is a high likelihood of serious secondary damage due to the spread of the fire. Prior art literature
[0003] Registered Patent No. 10-2303096 (Registration Date: September 10, 2021) Published Patent No. 10-2022-0149098 (Publication Date: November 8, 2022) Published Patent No. 10-2007-0043087 (Publication Date: April 25, 2007) Published Patent No. 10-2016-0145286 (Publication Date: December 20, 2016) The problem to be solved
[0004] Conventional battery storage cases had problems such as being difficult to carry due to the bulky and heavy weight of some fire-resistant containers, or being difficult to use while moving in aircraft, vehicles, or trains because they were manufactured in a fixed form. In addition, there were issues with low utility in daily life due to a lack of portability, making it difficult to apply to personal batteries (portable batteries, laptop batteries, etc.).
[0005] The present invention aims to solve the above-mentioned problems. Its purpose is to provide a portable storage case for an auxiliary battery that allows a user to store and carry the battery even when using means of transportation such as aircraft, vehicles, or trains.
[0006] In addition, the present invention aims to provide a portable storage case for an auxiliary battery that can effectively block the spread of fire to the outside even if the battery overheats and causes a fire. means of solving the problem
[0007] A portable storage case for an auxiliary battery according to the present invention comprises a fire extinguishing agent sheet and a case means, and is characterized by being portable. The fire extinguishing agent sheet can eject a fire extinguishing agent when overheated. The case means comprises a receiving container with one side open to accommodate an auxiliary battery, a cover coupled to the receiving container to open and close the open side of the receiving container, and a partition wall formed with a through hole so that the fire extinguishing agent can be ejected into the auxiliary battery, which is positioned so that the fire extinguishing agent sheet is inserted upright facing the auxiliary battery contained in the receiving container.
[0008] In addition, regarding the portable storage case of the above-mentioned auxiliary battery, it is preferable that the housing be made of a flame-retardant or heat-resistant material. Effects of the invention
[0009] According to the present invention, the portable storage case for the auxiliary battery can accommodate the auxiliary battery inside and be carried, making it easy to transport the auxiliary battery.
[0010] In addition, according to the present invention, the portable storage case of the auxiliary battery is formed of a flame-retardant or heat-resistant material, so even if a fire occurs in the auxiliary battery during transport, the spread of fire can be prevented.
[0011] In addition, according to the present invention, since a fire extinguishing agent sheet is contained inside the portable storage case of the auxiliary battery, when a fire occurs, the fire extinguishing agent is released to suppress the fire, and the heat can be prevented from spreading to the outside. Brief explanation of the drawing
[0012] FIG. 1 is a conceptual diagram of one embodiment of a portable storage case for an auxiliary battery according to the present invention. FIG. 2 is a cross-sectional view of an embodiment of FIG. 1, FIG. 3 is a conceptual diagram of the embodiment of FIG. 1 with the cover closed, Figure 4 is a conceptual diagram showing a fire occurring in an auxiliary battery in the embodiment of Figure 1. Specific details for implementing the invention
[0013] An embodiment of a portable storage case for an auxiliary battery according to the present invention will be described with reference to FIGS. 1 to 4.
[0014] A portable storage case according to the present invention includes a fire extinguishing agent sheet (10) and a case means (20).
[0015] The fire extinguishing agent sheet (10) has a fire extinguishing agent stored inside and can discharge the fire extinguishing agent when it overheats.
[0016] The case means (20) is equipped with a receiving container (21), a cover (23), and a partition (25).
[0017] One side of the receiving box (21) is open so that it can receive an auxiliary battery (1).
[0018] The cover (23) is attached to the receiving box (21) so as to open and close one side of the receiving box (21). The receiving box (21) can be opened and closed using the cover (23), and when the receiving box (21) is opened, the auxiliary battery (1) can be put into or taken out of the receiving box (21).
[0019] The partition (25) is formed inside the housing (21) so that the fire extinguishing agent sheet (10) can be inserted so that it can be positioned to face the auxiliary battery (1) housed inside the housing (21). Thus, when the cover (23) is open, the fire extinguishing agent sheet (10) can be inserted in the direction of arrow B. Then, the fire extinguishing agent sheet (10) faces the auxiliary battery (1) with the partition (25) in between. At this time, the partition (25) has a through hole (26) formed so that the fire extinguishing agent ejected from the fire extinguishing agent sheet (10) can be supplied to the auxiliary battery (1). Thus, when the auxiliary battery (1) overheats or a fire occurs, the fire extinguishing agent is ejected from the fire extinguishing agent sheet (10), and the ejected fire extinguishing agent passes through the through hole (26) as shown by arrow A and is supplied to the auxiliary battery (1) to cool the auxiliary battery (1) or suppress the fire.
[0020] Here, the case means (20) is formed of a heat-resistant material such as silicone fabric or a fire-resistant polymer, and is implemented with two or more heat-resistant layers to ensure durability and prevent the spread of fire.
[0021] In the case of this embodiment, the case means (20) is portable. Therefore, when carrying the auxiliary battery (1), it can be carried after being stored in the receiving container (21) of the case means (20) of this embodiment. At this time, if the auxiliary battery (1) overheats or a fire occurs, a fire extinguishing agent is ejected from the fire extinguishing agent sheet (10) to cool the auxiliary battery (1) or suppress the fire. Meanwhile, the case means (20) is made of a heat-resistant material to prevent the spread of fire. In addition, the fire extinguishing agent sheet (10) can be inserted into and removed from the receiving container (21) of the case means (20). Therefore, when the case means (20) is used and the fire extinguishing agent sheet (10) is consumed, it can be reused by replacing it with a new fire extinguishing agent sheet (10).
