The following describes an ignition material storage structure according to an embodiment of the present invention with reference to the drawings.

First Embodiment
First, an ignition material storage structure 100 according to a first embodiment will be described with reference to Fig. 1. Fig. 1 is a cross-sectional view of the ignition material storage structure 100. The ignition material storage structure 100 is a storage box for storing ignition materials such as secondary batteries and smoke bombs. The secondary batteries are, for example, lithium ion secondary batteries for vehicles. Note that in the following figures, illustrations of ignition materials are omitted.

As shown in FIG. 1, the ignition material storage structure 100 includes a metal body 10 that defines a storage space S for storing ignition materials. The metal forming the body 10 is, for example, steel, stainless steel, aluminum, aluminum alloy, titanium, etc.

The main body 10 is a box body including a pair of box members 11 and 12. The box member 11 has a recess 11a and an annular flange portion 11b extending from the opening edge of the recess 11a to the outside of the recess 11a. Like the box member 11, the box member 12 has a recess 12a and an annular flange portion 12b extending from the opening edge of the recess 12a to the outside of the recess 12a. The pair of box members 11 and 12 are formed from a metal plate having a thickness of 1 mm or more, more preferably a thickness of 1.6 mm or more.

The ignition material storage structure 100 is used with the flanges 11b and 12b overlapping each other so that the internal space of the recess 11a and the internal space of the recess 12a are connected to each other. The recesses 11a and 12a form the storage space S. A band (not shown) is hung across the flanges 11b and 12b to fasten the pair of box members 11 and 12 to each other.

The ignition material storage structure 100 further includes fire-resistant cloths 21 and 22 provided on the main body 10. For ease of explanation, the thicknesses of the fire-resistant cloths 21 and 22 are exaggerated in FIG. 1.

The fire-resistant cloth 21 is attached to the box member 11 and covers the inner surface of the recess 11a. The fire-resistant cloth 22 is attached to the box member 12 and covers the inner surface of the recess 12a. In other words, the fire-resistant cloths 21 and 22 cover the inner surface of the main body 10. The fire-resistant cloths 21 and 22 are attached to the box members 11 and 12 using members such as pins, screws, and screws.

The fire-resistant cloths 21 and 22 extend along the flange portions 11b and 12b, respectively. When the flange portions 11b and 12b are overlapped with each other, the fire-resistant cloths 21 and 22 are sandwiched between the flange portions 11b and 12b.

The fire-resistant cloths 21 and 22 are, for example, cloths made of non-flammable materials, and are also called "fireproof cloths." As the fire-resistant cloths 21 and 22, fireproof cloths made of Zylon (registered trademark), fireproof cloths made of glass fiber, and fireproof cloths made of silica fiber can be used. One or both surfaces of these fireproof cloths may be coated with a heat-resistant resin. As the fireproof cloth made of Zylon (registered trademark), the fire-extinguishing fireproof cloth Wizard WL-9090 manufactured by Tokyo Glass Machinery Co., Ltd., etc. can be used depending on the dimensions of the flammable material storage structure 100.

In this way, in the ignitable material storage structure 100, the storage space S is defined by the metal main body 10. Therefore, the ignitable material storage structure 100 can withstand an explosion of the ignitable material stored in the storage space S. In addition, the fire-resistant cloths 21 and 22 cover the inner surface of the main body 10. Therefore, even if the ignitable material stored in the storage space S ignites, the main body 10 will not be directly exposed to the flames. This prevents heat from being transferred to the main body 10 and prevents the main body 10 from melting, and prevents the flames from spreading to the outside of the ignitable material storage structure 100.

Figure 2A is a diagram showing an example of an ignition material storage structure 100 mounted on a box-type passenger car 1. Specifically, the ignition material storage structure 100 is installed in the lower part of the body of the box-type passenger car 1, the back of the rear seat of the box-type passenger car 1, and/or under the floor of the trunk of the box-type passenger car 1. The lower part of the body may be inside or outside the body. The ignition material storage structure 100 may be installed in another location of the box-type passenger car 1. If the ignition material is a battery, the box-type passenger car 1 may use the power stored in the battery.

Figure 2B is a diagram showing an example in which the ignition material storage structure 100 is mounted on a station wagon passenger vehicle 2. Specifically, the ignition material storage structure 100 is installed under the body of the station wagon passenger vehicle 2 and/or under the luggage room floor of the station wagon passenger vehicle 2. The underside of the body may be on the inside or outside of the body. The ignition material storage structure 100 may be installed in another location on the station wagon passenger vehicle 2. If the ignition material is a battery, the station wagon passenger vehicle 2 may use the power stored in the battery.

Figure 2C is a diagram showing an example of an ignition material storage structure 100 mounted on a bus 3. Specifically, the ignition material storage structure 100 is installed in the lower part of the body of the bus 3, the upper part of the roof of the bus 3, and/or the rear part of the body of the bus 3. The lower part of the body may be inside or outside the body. The ignition material storage structure 100 may be installed in another location on the bus 3. If the ignition material is a battery, the bus 3 may use the power stored in the battery.

Figure 2D is a diagram showing an example of an ignition material storage structure 100 mounted on a truck 4. Specifically, the ignition material storage structure 100 is installed in the lower part of the body of the truck 4 and/or the rear part of the cab of the truck 4. The lower part of the body may be inside or outside the body. The ignition material storage structure 100 may be installed in another location on the truck 4. If the ignition material is a battery, the truck 4 may use the power stored in the battery.

Figure 2E is a diagram showing an example of an ignition material storage structure 100 mounted on a railway vehicle 5. Specifically, the ignition material storage structure 100 is incorporated into the lower part of the body of the railway vehicle 5 and/or the upper part of the body of the railway vehicle 5. The lower part of the body may be on the inside or outside of the body. The ignition material storage structure 100 may be incorporated into another location on the railway vehicle 5. If the ignition material is a battery, the railway vehicle 5 may use the power stored in the battery.

Figure 2F is a diagram showing an example of an ignition material storage structure 100 mounted on a ship 6. Specifically, the ignition material storage structure 100 is incorporated into the hull of the ship 6. The ignition material storage structure 100 may also be incorporated in other locations on the ship 6. If the ignition material is a battery, the ship 6 may use the power stored in the battery.

Figure 2G is a diagram showing an example of an ignition material storage structure 100 mounted on an aircraft 7. Specifically, the ignition material storage structure 100 is installed in the front, middle, and/or rear of the aircraft 7's fuselage. The ignition material storage structure 100 may also be installed in other locations on the aircraft 7. If the ignition material is a battery, the aircraft 7 may use the power stored in the battery.

<First Modification of First Embodiment>
Next, an ignition material storage structure 101 according to a first modification of the first embodiment will be described with reference to Fig. 3. In the following, differences from the first embodiment will be mainly described, and the same or corresponding components as those described in the first embodiment will be denoted by the same reference numerals in the drawings and will not be described. For ease of explanation, the thicknesses of the fire-resistant cloths 21 and 22 are also exaggerated in Fig. 3.

In explosive materials such as secondary batteries, electrolyte may leak out. Since electrolyte permeates fabric, in the explosive material storage structure 100, when electrolyte leaks out from the explosive material stored in the storage space S, the electrolyte will reach the metal main body 10. If electrolyte reaches the metal main body 10 and a person touches the main body 10, there is a risk of receiving an electric shock. Therefore, the explosive material storage structure 101 employs a structure that prevents electric shock.

Figure 3 is a cross-sectional view of the ignition material storage structure 101. As shown in Figure 3, the ignition material storage structure 101 has electrical insulation layers 31, 32 provided on the metal body 10. The electrical insulation layers 31, 32 are, for example, heat-resistant rubber, bakelite, heat-resistant resin, etc.

The electrical insulating layer 31 covers the outer surface of the box member 11, and the electrical insulating layer 32 covers the outer surface of the box member 12. In other words, the electrical insulating layers 31 and 32 cover the outer surface of the main body 10. Therefore, the metal main body 10 is electrically insulated from the surroundings of the ignitable material storage structure 101. Therefore, even if electrolyte leaks from the ignitable material stored in the storage space S, electric shock can be prevented.

In the ignition material storage structure 101, even if the ignition material stored in the storage space S ignites, the main body 10 is not directly exposed to the flames. This prevents heat from being transferred to the main body 10 and prevents the main body 10 from melting, and prevents the flames from spreading to the outside of the ignition material storage structure 101.

<Second Modification of First Embodiment>
Next, an ignition material storage structure 102 according to a second modification of the first embodiment will be described with reference to Fig. 4. In the following, differences from the first embodiment will be mainly described, and the same or corresponding components as those described in the first embodiment will be denoted by the same reference numerals in the drawings and will not be described. For ease of explanation, the thicknesses of the fire-resistant cloths 21 and 22 are also exaggerated in Fig. 4.

Figure 4 is a cross-sectional view of the ignition material storage structure 102. As shown in Figure 4, the box member 12 in the ignition material storage structure 102 has a folded portion 12c that is folded back at the opening edge of the recess 12a. The flange portion 12b is located away from the folded portion 12c in the depth direction of the recess 12a. The fire-resistant cloth 22 covers the folded portion 12c in addition to the inner surface of the recess 12a.

When the flange portion 12b is overlapped with the flange portion 11b, the folded portion 12c is inserted into the recess 11a and is pressed into the inside of the recess 12a by the inner peripheral surface of the recess 11a. Therefore, the fireproof cloths 21 and 22 are compressed between the folded portion 12c and the recess 11a, and the gap between the folded portion 12c and the recess 11a is blocked. Therefore, even if the electrolyte leaks from the ignition material contained in the storage space S, the electrolyte can be prevented from leaking out from between the box members 11 and 12.

Even in the ignitable material storage structure 102, if the ignitable material stored in the storage space S ignites, the main body 10 is not directly exposed to the flames. This prevents heat from being transferred to the main body 10 and prevents the main body 10 from melting, and prevents the flames from spreading to the outside of the ignitable material storage structure 102.

<Third Modification of First Embodiment>
Next, an ignition material storage structure 103 according to a third modified example of the first embodiment will be described with reference to Fig. 5. In the following, differences from the second modified example of the first embodiment will be mainly described, and the same or corresponding components as those described in the second modified example of the first embodiment will be denoted by the same reference numerals as those in the first embodiment and will not be described. In Fig. 5, the thicknesses of the fire-resistant cloths 21 and 22 are also exaggerated for ease of explanation.

Figure 5 is a cross-sectional view of the ignition material storage structure 103. As shown in Figure 4, the box member 12 in the ignition material storage structure 103 has a folded portion 12c that is folded back at the opening edge of the recess 12a. The ignition material storage structure 103 has electrical insulation layers 31, 32 provided on the metal main body 10. The electrical insulation layers 31, 32 cover the outer surface of the main body 10. Therefore, the metal main body 10 is electrically insulated from the surroundings of the ignition material storage structure 103. Therefore, even if electrolyte leaks from the ignition material stored in the storage space S, electric shock can be prevented.

In the ignition material storage structure 103, even if the ignition material stored in the storage space S ignites, the main body 10 is not directly exposed to the flames. This prevents heat from being transferred to the main body 10 and prevents the main body 10 from melting, and prevents the flames from spreading to the outside of the ignition material storage structure 103.

In addition, in the ignition material storage structure 103, the fireproof cloths 21 and 22 are compressed between the folded portion 12c and the recessed portion 11a, and the gap between the folded portion 12c and the recessed portion 11a is blocked. Therefore, even if the electrolyte leaks from the ignition material stored in the storage space S, the electrolyte can be prevented from leaking out from between the box members 11 and 12.

<Fourth Modification of First Embodiment>
Next, an ignition material storage structure 104 according to a fourth modification of the first embodiment will be described with reference to Fig. 6. In the following, differences from the first embodiment will be mainly described, and the same or corresponding components as those described in the first embodiment will be denoted by the same reference numerals in the drawings and will not be described. For ease of explanation, the thicknesses of the fire-resistant cloths 21 and 22 are also exaggerated in Fig. 6.

Figure 6 is a cross-sectional view of the ignition material storage structure 104. As shown in Figure 6, the metal body 10 in the ignition material storage structure 104 includes a box member 13 having an opening, and a lid member 14 that closes the opening of the box member 13. In other words, the ignition material storage structure 104 is a top-lid type.

The fire-resistant cloth 21 is attached to the box member 13 and covers the inner surface of the box member 13. The fire-resistant cloth 22 is attached to the lid member 14. The lid member 14 is placed over the box member 13 so that the fire-resistant cloth 22 is positioned on the inner space side of the box member 13. In other words, the fire-resistant cloths 21 and 22 cover the inner surface of the main body 10. Therefore, even if the ignitable material stored in the storage space S ignites, the main body 10 will not be directly exposed to the flames. This prevents heat from being transferred to the main body 10 and prevents the main body 10 from melting, and prevents the flames from spreading to the outside of the ignitable material storage structure 104.

Fifth Modification of First Embodiment
Next, an ignition material storage structure 105 according to a fifth modified example of the first embodiment will be described with reference to Fig. 7. In the following, differences from the fourth modified example of the first embodiment will be mainly described, and the same or corresponding components as those described in the fourth modified example of the first embodiment will be denoted by the same reference numerals as those in the first embodiment and will not be described. In Fig. 7, the thicknesses of the fire-resistant cloths 21 and 22 are also exaggerated for ease of explanation.

Figure 7 is a cross-sectional view of the ignition material storage structure 105. As shown in Figure 7, the ignition material storage structure 105 is a top-lid type.

The electrical insulating layer 31 covers the outer surface of the box member 13. The electrical insulating layer 32 covers the outer surface of the lid member 14 (the surface opposite the internal space of the box member 13 when the lid member 14 is placed over the box member 13 so that the fireproof cloth 22 is located on the internal space side of the box member 13). In other words, the electrical insulating layers 31 and 32 cover the outer surface of the main body 10. Therefore, the metal main body 10 is electrically insulated from the surroundings of the ignitable material storage structure 105. Therefore, even if electrolyte leaks from the ignitable material stored in the storage space S, electric shock can be prevented.

In the ignition material storage structure 105, even if the ignition material stored in the storage space S ignites, the main body 10 is not directly exposed to the flames. This prevents heat from being transferred to the main body 10 and prevents the main body 10 from melting, and prevents the flames from spreading to the outside of the ignition material storage structure 101.

Sixth Modification of First Embodiment
Next, an ignition material storage structure 106 according to a sixth modified example of the first embodiment will be described with reference to Figures 8A and 8B. In the following, differences from the fourth modified example of the first embodiment will be mainly described, and the same or corresponding components as those described in the fourth modified example of the first embodiment will be denoted by the same reference numerals as those in the first embodiment and will not be described. In Figures 8A and 8B, the thicknesses of the fire-resistant cloths 21 and 22 are also exaggerated for ease of description.

Figure 8A is a cross-sectional view of the ignition material storage structure 106, showing the ignition material storage structure 106 in a closed state. Figure 8B is a cross-sectional view of the ignition material storage structure 106, showing the ignition material storage structure 106 in an open state. As shown in Figures 8A and 8B, the ignition material storage structure 106 has a receiving stand 41 housed in a box member 13. The ignition material is placed on the receiving stand 41 and stored.

The lid member 14 is connected to the box member 13 via a hinge 42. When the lid member 14 rotates around the hinge 42, the ignition material storage structure 106 is opened or closed. In other words, the ignition material storage structure 106 is of a side-entry type.

The fire-resistant cloth 21 is attached to the box member 13 and covers the inner surface of the box member 13. The fire-resistant cloth 22 covers the inner surface of the lid member 14 (the surface facing the internal space of the box member 13 when the lid member 14 is closed). Therefore, even if the ignitable material stored in the storage space S ignites, the main body 10 will not be directly exposed to the flames. This prevents heat from being transferred to the main body 10 and prevents the main body 10 from melting, and prevents the flames from spreading to the outside of the ignitable material storage structure 104.

Seventh Modification of First Embodiment
Next, an ignition material storage structure 107 according to the seventh modified example of the first embodiment will be described with reference to Figures 9A and 9B. In the following, differences from the sixth modified example of the first embodiment will be mainly described, and the same or corresponding configurations as those described in the sixth modified example of the first embodiment will be denoted by the same reference numerals as those in the first embodiment and will not be described. In Figures 9A and 9B, the thicknesses of the fire-resistant cloths 21 and 22 are also exaggerated for ease of description.

Figure 9A is a cross-sectional view of the ignition material storage structure 107, showing the ignition material storage structure 107 in a closed state. Figure 9B is a cross-sectional view of the ignition material storage structure 107, showing the ignition material storage structure 107 in an open state. As shown in Figures 9A and 9B, the ignition material storage structure 107 is of a horizontal entry type.

The electrical insulating layer 31 covers the outer surface of the box member 13. The electrical insulating layer 32 covers the outer surface of the lid member 14 (the surface opposite the internal space of the box member 13 when the lid member 14 is closed). In other words, the electrical insulating layers 31 and 32 cover the outer surface of the main body 10. Therefore, the metal main body 10 is electrically insulated from the surroundings of the ignitable material storage structure 107. Therefore, even if electrolyte leaks from the ignitable material stored in the storage space S, electric shock can be prevented.

Even in the ignition material storage structure 107, if the ignition material stored in the storage space S ignites, the main body 10 is not directly exposed to the flames. This prevents heat from being transferred to the main body 10 and prevents the main body 10 from melting, and prevents the flames from spreading to the outside of the ignition material storage structure 101.

Although not shown, the ignition material storage structures 101 to 107 according to the first to seventh modified examples of the first embodiment are mounted on a box-type passenger car 1 (see FIG. 2A), a station wagon passenger car 2 (see FIG. 2B), a bus 3 (see FIG. 2C), a truck 4 (see FIG. 2D), a railroad car 5 (see FIG. 2E), a ship 6 (see FIG. 2F), and an aircraft 7 (see FIG. 2G), just like the ignition material storage structure 100.

Second Embodiment
Next, an ignition material storage structure 200 according to a second embodiment will be described with reference to Figures 10A to 10D. Figure 10A is an elevation view (front view) of the ignition material storage structure 200. Figure 10B is a plan sectional view of the ignition material storage structure 200. Figure 10C is an elevation view (side view) of the ignition material storage structure 200. Figure 10D is a vertical sectional view of the ignition material storage structure 200. The ignition material storage structure 100 is a storage for storing ignition materials such as secondary batteries and smoke bombs. The secondary battery is, for example, an in-vehicle lithium ion secondary battery. Note that in the following figures, illustrations of ignition materials are omitted.

As shown in Figures 10A to 10D, the ignition material storage structure 200 includes a metal body 210 that defines a storage space S for storing ignition materials. The metal forming the body 210 is, for example, steel, stainless steel, aluminum, aluminum alloy, titanium, etc.

The main body 210 is a warehouse structure including multiple plate members 211 and shutters 212. Some of the plate members 211 extend vertically and are supported by multiple metal pillars 213 erected on the ground, forming the side walls of the flammable material storage structure 200. The other plate members 211 are installed horizontally across the multiple metal pillars 213, forming the floor and roof of the flammable material storage structure 200.

A part of the side wall of the ignition material storage structure 200 is formed by a shutter 212. The shutter 212 can slide up and down. When the shutter 212 is raised, the ignition material storage structure 200 is opened, and it is possible to enter and exit the ignition material storage structure 200. When the shutter 212 is lowered, the ignition material storage structure 200 is closed, and it is not possible to enter or exit the ignition material storage structure 200.

The plate member 211 and the shutter 212 are formed from a metal plate having a thickness of 1 mm or more, more preferably a thickness of 1.6 mm or more. The floor of the ignition material storage structure 200 may be formed from concrete.

The ignition material storage structure 200 further includes fire-resistant cloths 221, 222 provided on the main body 210. For ease of explanation, the thickness of the fire-resistant cloths 221, 222 is exaggerated in Figures 10A to 10D.

The fire-resistant cloth 221 covers the inner surface of the plate member 211 (the surface facing the storage space S). The fire-resistant cloth 222 covers the inner surface of the shutter 212 (the surface facing the storage space S when the shutter 212 is lowered). In other words, the fire-resistant cloths 221 and 222 cover the inner surface of the main body 10. The fire-resistant cloths 221 and 222 are attached to the plate member 211 and the shutter 212 using members such as pins, screws, and bolts.

The fire-resistant cloths 221 and 222 are, for example, cloths made of non-flammable materials, and are also called "fireproof cloths." As with the first embodiment, fireproof cloths made of Zylon (registered trademark), fireproof cloths made of glass fiber, and fireproof cloths made of silica fiber can be used as the fireproof cloths 221 and 222. One or both surfaces of these fireproof cloths may be coated with a heat-resistant resin. As the fireproof cloth made of Zylon (registered trademark), the fireproof cloth Wizard WL-9090 manufactured by Tokyo Glass Machinery Co., Ltd., or the like can be used depending on the dimensions of the flammable material storage structure 100.

In this way, in the ignitable material storage structure 200, the storage space S is defined by the metal main body 210. Therefore, the ignitable material storage structure 200 can withstand an explosion of the ignitable material stored in the storage space S. In addition, the fire-resistant cloths 221, 222 cover the inner surface of the main body 210. Therefore, even if the ignitable material stored in the storage space S ignites, the main body 210 will not be directly exposed to the flames. This prevents heat from being transferred to the main body 210 and prevents the main body 210 from melting, and prevents the flames from spreading to the outside of the ignitable material storage structure 200.

Although not shown in the figure, a water discharge device may be provided on the ceiling of the flammable material storage structure 200. When flammable materials stored in the storage space S catch fire, the fire can be extinguished by discharging water from the water discharge device.

Although the embodiments of the present invention have been described above, the above embodiments merely show some of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments.

In the first embodiment, the case where the ignitable material storage structure 100 is a storage box is described, and in the second embodiment, the case where the ignitable material storage structure 200 is a storage warehouse is described, but the present invention is not limited to these forms.
