Detailed Description

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a front view of a battery housing box according to an embodiment of the present invention, and fig. 2 is a plan view.

The battery storage case 1 is a rectangular parallelepiped storage case that detachably stores the battery case 2, and can be disposed outdoors and used. For example, the battery housing box 1 is used as an emergency power supply for supplying power to equipment to be used even when power failure occurs due to a disaster.

The respective directions such as the vertical direction shown in fig. 1, fig. 2, and the later-described figures correspond to the respective directions when the battery housing case 1 is used. For example, the left-right direction coincides with the longitudinal direction of the battery storage case 1, and handles for a user to hold when moving the battery storage case 1 may be provided at both left and right ends of the battery storage case 1. The front side is a user side for performing various operations (replacement of the battery box 2, etc.) on the battery housing box 1, and the rear side is provided on a wall side when the battery housing box 1 is disposed close to the wall, for example, in consideration of the installation position of the battery housing box. However, each direction may be changed as appropriate depending on the use situation and the like.

The battery case 2 is a unit that supports a plurality of air batteries 10 (fig. 7 and 8 described later). By replacing the battery box 2, the plurality of air batteries 10 can be replaced together. The battery case 2 can have any structure as long as it has a structure for simultaneously supporting a plurality of air batteries 10 and exposing at least a part of each air battery 10.

the battery housing box 1 includes: an inner case 3 for detachably housing the battery case 2; and an outer case 4 surrounding the inner case 3 with a heat insulating space using air therebetween around the inner case 3, wherein the battery housing case 1 is made of plastic cardboard. The plastic cardboard is a sheet made of polypropylene having a hollow structure, and is a material that is impermeable to water, light, and easily bendable.

Each part constituting the battery housing case 1 is manufactured by cutting a plastic cardboard and bending it appropriately. The respective portions are joined to each other by a known fastener (indicated by reference numeral 5 in fig. 1) such as a rivet or a clip made of heat-welded or plastic. Therefore, as compared with the case where the battery housing case 1 is made of metal, it is possible to obtain a desired strength and reduce the weight, and it is possible to avoid the initial cost such as the die cost of the resin molded product.

The inner case 3 is formed into a rectangular box body having an open upper side, and has a rectangular plate-shaped bottom plate 3A that is horizontal to the floor G, and rectangular plate-shaped side walls 3B that are erected from the bottom plate 3A and cover the front, rear, left, and right of the battery case 2.

The outer box 4 has a rectangular box 4A opened upward and a cover 4B openably and closably covering the box 4A from above, and the outer box 4 supports the box 4A by a plurality of legs 4C so as to be spaced from the floor G. As shown in fig. 1, the cover 4B is joined to the case 4A by a plurality of fixing members 5, and a part of the cover 4B is bent, whereby opening and closing can be performed without providing a separate hinge member.

The casing 4A of the outer box 4 has a rectangular plate-shaped bottom plate 5A that is horizontal to the floor G, and a rectangular plate-shaped side wall 5B that is erected from the outer periphery of the bottom plate 5A. The bottom plate 5A of the outer box 4 and the bottom plate 3A of the inner box 3 may be the same member or different members. Hereinafter, for convenience of explanation, the bottom plate 3A of the inner box 3 will be described as "inner bottom plate 3A", and the side wall 3B of the inner box 3 will be described as "inner side wall 3B".

As shown in fig. 2, the inner side wall 3B has an inner front wall 3F, an inner rear wall 3G, an inner left wall 3L, and an inner right wall 3R located in front, rear, left, and right of the battery case 2.

The side wall 5B of the outer box 4 has: a front wall 5F disposed forward with a gap S1 therebetween from the inner front wall 3F; a rear wall 5G disposed rearward with a gap S2 from the inner rear wall 3G; a left wall 5L disposed on the left with a gap S3 therebetween and the inner left wall 3L; and a right wall 5R disposed rightward with a gap S4 therebetween from the inner right wall 3R.

The spaces corresponding to the gaps S1 to S4 are cavities, and the cavities are filled with air. Accordingly, the spaces corresponding to the gaps S1 to S4 become heat insulation spaces in which the heat insulation effect by the air can be obtained. Hereinafter, the spaces corresponding to the gaps S1 to S4 are referred to as heat insulation spaces S1 to S4.

Fig. 3 is a view of the battery housing case 1 when the lid 4B is opened. In fig. 3, the battery case 2 is omitted.

As shown in fig. 3, since the heat insulating spaces S1 to S4 are formed all over the front, rear, left, and right of the inner box 3, it is possible to suppress a temperature rise in the interior of the inner box 3 due to the influence of direct sunlight or the like. This can suppress a temperature rise of the battery case 2 inside the inner case 3. Further, the temperature inside the inner box 3 can be stabilized more than the outside space in winter and summer.

The lid 4B is formed larger than the case 4 when the battery housing case 1 is viewed in plan. Thus, by closing the lid 4B, a gap (corresponding to a part of the gap 8D in fig. 5 described later) for allowing air to enter and exit can be secured between the lid 4B and the outer box 4 while preventing rainwater and the like from entering from above.

Further, lid 4B is provided with a plurality of cushioning members 6A, and these cushioning members 6A abut against the upper surface of battery case 2 inside inner case 3 when lid 4B is closed. Thus, when the lid 4B is closed, a gap S5 (fig. 5 described later) into which the cushioning member 6A is inserted is formed between the lid 4B and the battery case 2, and this gap S5 also functions as a heat insulating space using air. Therefore, it is possible to suppress a temperature rise in the inner box 3 due to the influence of direct sunlight or the like irradiated to the lid 4B.

A sealing gasket 6B (shown by hatching in fig. 3) is further provided on the inner surface of the lid 4B, and this sealing gasket 6B closes the upper opening of the heat insulating space S2 when the lid 4B is closed.

Fig. 4 is a side view of the battery housing case 1 shown in fig. 3. In fig. 4, the battery case 2 is indicated by a two-dot chain line.

As shown in fig. 3 and 4, a power supply unit 7 is housed in the heat insulating space S2, and the power supply unit 7 converts dc power output from the air battery 10 in the battery box 2 into predetermined power and supplies the converted power to a load. The power supply unit 7 includes a panel 7A positioned above the heat insulating space S2 and a mounting board provided on the back side of the panel 7A, and the panel 7A is provided with an output terminal and the like for outputting the converted electric power.

Since the power supply unit 7 is disposed in the heat insulating space S2, the battery housing box 1 can be made smaller and the temperature rise of the power supply unit 7 due to the influence of direct sunlight or the like can be suppressed, as compared with a case where a separate disposition space for the power supply unit 7 is provided.

As a power supply unit that converts the DC power into predetermined power, a converter (DC-DC converter) or an inverter (DC-AC inverter) may be used.

Since the upper opening of the heat insulating space S2 is closed by the sealing gasket 6B provided in the lid body 4B, the independence of the heat insulating space S2 can be improved, and the heat insulating property and the sealing property with the surroundings can be further improved. Since the sealing property can be improved, the reaction gas or the like of the air battery 10 can be effectively prevented from flowing into the heat insulating space S2.

Further, a sealing gasket 6C (see fig. 3 and 4) is provided at the upper end of the position corresponding to the inner rear wall 3G, the inner left wall 3L, the inner right wall 3R, and the rear wall 5G forming the heat insulation space S2. Therefore, the power supply cable connected to the output terminal of the power supply unit 7 is sandwiched between the sealing gaskets 6C and 6B, and thus the sealing property of the heat insulating space S2 is sufficiently ensured. The sealing gaskets 6C and 6B can be widely used as known gaskets such as rubber gaskets.

As shown in fig. 3 and 4, the inner bottom plate 3A is provided with a plurality of support members 8A for supporting the battery case 2 in a floating manner, and a plurality of holes 8B (see fig. 3) functioning as air vents for allowing air to flow into the inner case 3 are provided between the support members 8A. The air battery 10 can be supported in a floating manner while being positioned by these support members 8A, and air from below can be made to flow into the inside of the inner case 3 by the holes 8B.

a filter 8C (shown by a two-dot chain line in fig. 3) covering the plurality of holes 8B is placed on the inner bottom plate 3A. These filters 8C have air permeability, and prevent foreign matter such as bugs from entering the holes 8B. As described above, since the battery housing case 1 is supported by the leg portion 4C in a floating manner on the floor surface G, air can easily flow into the battery housing case 1, and moisture on the floor surface G does not enter the battery housing case 1.

Fig. 5 is a V-V sectional view of fig. 2. Here, as shown in fig. 4 and 5, the left and right side walls (left wall 5L, right wall 5R) of the outer box 4 are formed lower than the front and rear side walls (front wall 5F, rear wall 5G). The left and right side walls (inner left wall 3L, inner right wall 3R) of the inner box 3 are also formed lower than the front and rear side walls (front wall 5F, rear wall 5G) of the outer box 4. As a result, as shown in fig. 5, a gap 8D functioning as a vent through which air enters and exits is formed between the lid body 4B and the left and right side walls (the left wall 5L and the right wall 5R).

That is, when the lid 4B is closed, the lid 4B abuts a part of the side wall 5B, and a gap 8D functioning as a vent is formed between the lid 4B and the other part of the side wall 5B.

Here, in fig. 5, arrows indicate an example of the air flow from the holes 8B provided in the inner floor panel 3A. As shown in fig. 5, the air flowing from the hole 8B can flow from the inner box 3 to the outside through the left and right gaps 8D.

Fig. 6 is a cross-sectional view VI-VI of fig. 2. As shown in fig. 6, the heat insulating space S1 of the heat insulating spaces S1 to S4 is open at the lower side. An opening 8E is formed in the inner front wall 3F, which is a partition member that partitions the heat insulating space S1 and the inside of the inner box 3, and this opening 8E allows air that has flowed into the heat insulating space S1 to flow into the inside of the inner box 3 as indicated by an arrow in fig. 6. This makes it possible to flow air into the inside of the inner box 3 while suppressing a temperature rise in the inside of the inner box 3 due to the influence of direct sunlight from the front side or the like.

In this way, in the present configuration, since the hole 8B, the gap 8D, and the opening 8E, which function as vents for allowing outside air to enter and exit the inside of the inner case 3, it is possible to supply sufficient air to the air battery 10 and to discharge gas and heat generated by the battery reaction to the outside. Further, since the heat insulation spaces S1 to S4 are provided at least in the front, rear, left, and right of the inner box 3, it is possible to effectively suppress a temperature change in the inside of the inner box 3 due to direct sunlight or the like.

(for air battery)

Next, an example of the air battery 10 housed in the battery housing case 1 will be described.

Fig. 7 is a front view of the air battery 10, and fig. 8 is a sectional view of each air battery 10 in the battery case 2.

The air battery 10 includes a hollow box-shaped exterior body 11 (also referred to as a battery can or a battery case), an air electrode 13 exposed to the outside of the exterior body 11, and a metal electrode 15 (fig. 8) housed inside the exterior body 11. The air battery 10 is a magnesium air battery using a magnesium alloy as the metal electrode 15, and the electrolyte is an aqueous sodium chloride solution. The air battery 10 is a primary battery in which an electrolyte is injected into the exterior 11 to cause the air electrode 13 to function as a positive electrode and the metal electrode 15 to function as a negative electrode. In fig. 8, symbol UL indicates the position of the upper surface of the electrolyte solution.

The exterior body 11 integrally has: a bottom plate portion 21 that constitutes a bottom surface of the exterior body 11; a front wall portion 22 constituting a front surface; a rear wall portion 23 (fig. 8) constituting a rear surface; left and right side wall portions (left and right wall portions) 24 that constitute left and right side surfaces; and an upper plate portion 25 constituting an upper surface. The front wall portion 22 and the rear wall portion 23 are surfaces (lateral long surfaces) having the same shape and longer in the horizontal direction than in the vertical direction, are arranged in parallel with each other, and are formed as the largest surfaces in the exterior body 11.

The front wall 22 and the rear wall 23 are provided with an opening 22K covered with the air electrode 13. In the air battery 10, since the air electrodes 13 are disposed on both sides of one metal electrode 15, the air electrode area can be increased. The air battery 10 may be configured to have one metal electrode 15 and one air electrode 13, and the number of the electrode plates is not limited.

The exterior body 11 is formed by bending a sheet containing paper. Specifically, as shown in fig. 8, the bottom plate portion 21 is formed in a V-shape protruding downward in a side view, and thereby the lower end of the metal electrode 15 is positioned by the downward protruding portion 21T.

The upper plate portion 25 is formed by bending the upper ends of the front wall portion 22 and the rear wall portion 23 as shown in fig. 8. The upper plate portion 25 has bent portions 25A, 25B, 25C, and 25D that are alternately bent downward in front of the metal electrode 15 or beyond the metal electrode 15 so as to sandwich the upper portion of the metal electrode 15 from the front wall portion 22 and the rear wall portion 23 side, and the upper portion of the metal electrode 15 is supported by these bent portions 25A to 25D. Thereby, the upper plate portion 25 also serves as a support member for supporting the metal electrode 15.

The bent portions 25A and 25C are portions formed by bending the front wall portion 22 side, and the bent portions 25B and 25D are portions formed by bending the rear wall portion 23 side. Gaps SF and SR having the same width are provided on both sides of the metal electrode 15, and the spaces corresponding to the gaps SF and SR are filled with the electrolyte.

The sheet material to be the exterior body 11 is formed by using a sheet material having a film provided on the surface of paper constituting a base material as a blank material, and sequentially performing a cutting step (also referred to as a rotary sheet pressing step), a punching step, and a peeling step on the blank material, and is generally referred to as a blank, a blank sheet, or a punched sheet.

The air electrode 1 is integrally formed by pressing (punching) a catalyst sheet 13B constituting a catalyst layer on both surfaces of a rectangular copper mesh 13A constituting a current collector. A part of the copper mesh 13A is exposed to the outside of the catalyst sheet 13B, and the exposed part is used as a terminal 13T of the air electrode 13. The air electrode 13 has air permeability that allows outside air to pass through to the inside of the exterior body 11 and water impermeability that prevents leakage of the electrolyte. In addition, the water impermeability may be secured by providing a sheet having water impermeability separately.

the air battery 10 is not limited to the above configuration, and a configuration of a known air battery can be widely applied. For example, the following structure may be adopted: a bag containing sodium chloride as a dielectric is disposed inside the outer package 11, and when water such as tap water is injected, power generation is performed.

The metal electrode 15 is not limited to a magnesium alloy, and other materials may be used. Examples of the other material include metals such as zinc, iron, and aluminum, and alloys containing any of these metals.

As described above, the battery housing case 1 of the present embodiment includes: an inner case 3 for detachably housing the air battery 10; and an outer box 4 surrounding the inner box 3 with insulating spaces S1 to S5 using air therebetween around the inner box 3. The outer box 4 forms heat insulating spaces S1 to S4 at least in the front, rear, left, and right directions of the inner box 3, and has ventilation ports (holes 8B, gaps 8D, and openings 8E) for allowing outside air to enter and exit the inside of the inner box 3. This makes it possible to supply sufficient air to the air cell 10, and to discharge the gas and heat generated by the cell reaction to the outside, thereby further suppressing the temperature change in the inside of the inner box 3 due to direct sunlight or the like. Therefore, the battery housing case 1 suitable for disposing the air battery 10 outdoors can be provided.

Further, the outer box 4 has: side walls 5B forming heat insulation spaces S1 to S4 between the inner box 3 and the side walls and extending in the front, rear, left, and right directions of the inner box 3; and a lid 4B openably and closably covering the internal space surrounded by the side wall 5B from above, wherein when the lid 4B is closed, the lid 4B abuts against a part of the side wall 5B, and a gap 8D functioning as a vent is provided between the lid 4B and the other part of the side wall 5B. This prevents the cover 4B from rainwater entering, and allows air to flow through the gap 8D formed between the cover 4B and the side wall 5B.

Further, a leg portion 4C projecting downward from the battery housing case 1 is provided, and a hole 8B functioning as a vent for allowing outside air to enter and exit the inside of the inner case 3 and a filter 8C for preventing foreign matter from entering the hole 8B are provided in the inner bottom plate 3A. This allows air to flow through the battery housing case 1, and prevents foreign matter from entering from below.

Further, since the support member 8A for supporting the air battery 10 in a floating manner is provided on the inner bottom plate 3A, air can easily flow in through the hole 8B provided in the inner bottom plate 3A.

Further, since the lower portion of the heat insulating space S1 in front of the inner box 3 is open, and the heat insulating space S1 is provided with the opening portion 8E through which the air flowing in from below flows into the inner box 3, the heat insulating space S1 can insulate the inner box 3, and the outside air can be supplied to the inside of the inner box 3 through the heat insulating space S1.

Further, without being limited to this configuration, the lower portions of the other heat insulating spaces S2 to S3 may be opened, and the opening 8E through which the air flowing from the lower portion flows into the inside of the inner box 3 may be provided. In short, it is sufficient to open the lower side of 1 or more of the heat insulation spaces S1 to S4 located in the front, rear, left, and right of the inner box 3, and provide the opening 8E through which the air flowing in from below flows into the inner box 3.

Further, since the power supply unit 7 is housed in the heat insulating space S2 and the sealing gasket 6B is provided between the heat insulating space S2 in which the power supply unit 7 is housed and the lid 4B, it is possible to effectively prevent moisture or foreign matter from entering the power supply unit 7.

The power supply unit 7 is not limited to the structure in which it is provided in the heat insulation space S2, and may be provided in any one of the heat insulation spaces S1 to S4. A plurality of the heat insulating spaces S1 to S4 may be used as arrangement spaces for components such as the power supply unit 7.

further, since the battery housing case 1 is formed of a plastic cardboard, strength that can be used repeatedly can be obtained, weight reduction can be achieved, and initial cost such as die cost can be avoided, which is also advantageous in cost reduction. The material of the battery housing case 1 is not limited to plastic cardboard. For example, other sheets having a hollow configuration than plastic cardboard may also be used. By using a hollow plate material, the battery housing case 1 can be made lighter and can be easily transported.

In addition, in the case where weight reduction of the battery housing case 1 is not necessary or durability is more required, a plate material other than the hollow structure may be used, and the material may be appropriately changed.

The present invention is not limited to the above-described embodiments, and various modifications and changes can be made according to the technical idea of the present invention.

For example, the battery housing box 1 may have a housing box 100, and the housing box 100 may house a bottle filled with a liquid to be injected into the air battery 10. Fig. 9 (a) is a front view of the battery housing case 1 having the housing case 100, and fig. 9 (B) is a side view.

The storage box 100 includes a rectangular parallelepiped box 100A having an upper opening and a lid 100B openably and closably covering the box 100A from above, and the storage box 100 constitutes a hollow box. The housing box 100 is formed as a cavity so as to be able to house a plurality of bottles filled with an electrolyte, and the housing box 100 is arranged to overlap the upper surface of the battery housing box 1 so as to cover the entire upper surface of the battery housing box 1.

In the storage case 100, an electrolyte solution is always provided in the vicinity of the battery storage case 1. In addition, the temperature rise in the battery housing box 1 due to direct sunlight can be suppressed by the housing box 100. This can further suppress the air battery 10 from being susceptible to an increase in temperature due to direct sunlight or the like.

In the above-described embodiment, the battery storage case 1 is formed in a rectangular parallelepiped shape, but the present invention is not limited to the rectangular parallelepiped shape. The shape of each member of the battery housing case 1 may be appropriately changed, and for example, the side walls 3B and 5B may not be limited to a rectangular frame shape in a plan view, and may be a polygonal frame shape other than a rectangular frame shape or a frame shape along a circle. The shapes, positions, and the like of the holes 8B, the gaps 8D, and the openings 8E serving as the air vents can be changed as appropriate.

Further, although the case where the plurality of air batteries 10 are housed in the battery housing box 1 by the battery box 2 has been described, the plurality of air batteries 10 may be housed in the battery housing box 1 as they are.
