Description

Technical Field

[0001] The present invention relates to a battery installation stand and a battery installation structure for fixing a household battery to an installation surface such as a building foundation or the ground.

Background Art

[0002] In a household solar power generation system, a solar panel (solar cell module) is installed on the roof of a building, and a household battery (hereinafter simply referred to as "battery") for storing electricity generated by the solar panel is used. Many of these batteries have a capacity (storage capacity) of 10 to 15 kWh, but some large-capacity batteries exceeding 15 kWh are also used. The size of the battery is the same as or larger than that of an outdoor unit of an air conditioner, and some are larger than two outdoor units. The weight of the battery is generally 100 to 200 kg, and some exceed 200 kg. As described above, the battery is a large and heavy equipment for household use. It is installed to be applicable to natural environments such as wind, rain, and earthquakes, and various proposals have been made regarding the installation structure of the battery in order to reduce the load of installation work and the like.

[0003] For example, Patent Document 1 (Japanese Patent No. 5291822) discloses a building equipment installation structure for installing a battery as building equipment on the outdoor side of a building. A battery 6 is installed via a pedestal 具有5 having an internal space available for wiring from the battery 6 on a building equipment installation foundation (battery installation foundation 2). The legs of the battery 6 are fixed to the upper surface of the pedestal 5 with bolts and nuts, and the pedestal 5 is fixed to the battery installation foundation 2 with anchor bolts 7. However, in the building equipment installation structure described in Patent Document 1, the frame 5 is fixed to the battery installation foundation 2 by anchor bolts 7, but the battery 6 and the frame 5 are only fixed to the legs of the battery 6 and the top surface of the frame 5 with bolts and nuts. Therefore, if a large force acts on the battery 6 from the front horizontal direction, or if lateral shaking occurs due to an earthquake, an excessive force will act on the fixing part between the legs of the battery 6 and the frame 5, causing the fixing part to deform or break, resulting in problems such as the battery 6 no longer being fixed to the frame 5 or the battery 6 tipping over. This problem is particularly pronounced when the battery 6 has a small base area and is tall.

[0004] Furthermore, Patent Document 2 (Japanese Unexamined Patent Publication No. 2019-207847) discloses an energy storage system comprising a storage battery 32, a housing 33 for housing the storage battery 32, and a pair of support members 11a and 11b for supporting the housing 33, wherein the lower surface (second flat plate portion 13a) of the support member 11a (11b), which is made of H-beam, is fixed to a foundation block 36 by anchor bolts 37, and the upper surface (first flat plate portion 12a) of the support member 11a (11b) is fixed to a pair of legs 47 and 48 of the housing 33 with bolts 34 and nuts 35. However, the energy storage system described in Patent Document 2 involves fixing a housing 33 containing a battery 32 to a base block 36 via a pair of supports 11a and 11b, and is not applicable to fixing a battery that is not housed in a housing. Furthermore, in the energy storage system of Patent Document 2, similar to Patent Document 1, the fixing of the housing 33 to the support bodies 11a and 11b is only done by fixing the legs 47 and 48 of the housing 33 to the support bodies 11a and 11b with bolts 34 and nuts 35, which leads to the same problems as the building equipment installation structure of Patent Document 1.

[0005] In this regard, Patent Document 3 (Japanese Patent Publication No. 2017-155459) discloses an equipment mounting structure in which a horizontal member 2 is fixed to the surface of the tiled exterior wall 1a of a building 1, and equipment (a stationary water heater 3 and a storage battery body) is attached to the upper part of this horizontal member 2 via a mounting bracket 4, and a base 6 is placed on the side of the foundation 1c located below the tiled exterior wall 1a, and the equipment is installed on this base 6. However, in the equipment mounting structure described in Patent Document 3, the equipment is attached to a horizontal member 2 fixed to the tiled exterior wall 1a of the building 1 via a mounting bracket 4, so the equipment cannot be installed in places where there is no exterior wall of the building. Furthermore, in the equipment mounting structure described in Patent Document 3, since the horizontal member 2 is fixed to the tiled exterior wall 1a of the building 1, not only does it impair the appearance of the tiled exterior wall 1a, but since the horizontal member 2 is fixed to the tiled exterior wall 1a with screws, when the equipment and the horizontal member 2 are removed, screw holes remain in the tiled exterior wall 1a, which also impairs the appearance of the tiled exterior wall 1a.

In this state, the lower end of the arm plate 15 is inserted between the clamping plate 14Q and the clamping plate 14R so that it is sandwiched between them, the shaft bolt 27 is inserted through the shaft hole 14Rh of the clamping plate 14R, the shaft hole 15h1 of the arm plate 15, and the shaft hole 14Qh of the clamping plate 14Q, and the shaft nut 28 is screwed onto the shaft bolt 27. In this way, as shown in Figure 9(a), the base plate 13 of the panel fixing bracket 12 is temporarily fixed to the upper surface of the raised object 9, and the arm plate 15 is attached to the clamping plates 14Q and 14R of the panel fixing bracket 12. In this case, the attachment of the arm plate 15 to the clamping plates 14Q and 14R may be performed before fixing the base plate 13 of the panel fixing bracket 12 to the upper surface of the raised object 9. Next, the intermediate panel 16 is positioned so that the upper end of the arm plate 15 is sandwiched between the clamping plates 16Q and 16R on the back of the intermediate panel 16. The shaft bolt 29 is then inserted through the shaft hole 16Rh of the clamping plate 16R, the shaft hole 15h2 of the arm plate 15, and the shaft hole of the clamping plate 16Q, and the shaft nut 30 is screwed onto the shaft bolt 2. In this way, as shown in Figure 9(b), the clamping plates 16Q and 16R on the back of the intermediate panel 16 are attached to the arm plate 15.

[0040] Next, the back of the support panel 17 is placed against the front of the intermediate panel 16, so that the holes 17a1, 17b1, 17c1, and 17d1 of the support panel 17 overlap with the holes 16a, 16b, 16c, and 16d of the intermediate panel 16. The tightening bolts 31a, 31b, 31c, and 31d are then inserted through the holes 17a1 and 16a, 17b1 and 16b, 17c1 and 16c, and 17d1 and 16d, respectively, and the tightening nuts 32a, 32b, 32c, and 32d are screwed onto the respective tightening bolts. Next, the upper plate 18U and lower plate 18S of the engaging plate 18 are placed against the front of the support panel 17, so that the elongated holes 18a and 18b of the upper plate 18U overlap with the holes 17a2 and 17b2 of the support panel 17, and the elongated holes 18c and 18d of the lower plate 18S overlap with the holes 17c2 and 17d2 of the support panel 17. Then, the tightening bolts 33a, 33b, 33c, and 33d are inserted through the elongated holes 18a and 17a2, 18b and 17b2, 18c and 17c2, and 18d and 17d2, respectively, and the tightening nuts 34a, 34b, 34c, and 34d are screwed onto the respective tightening bolts. Furthermore, the fixing bolt 24a is inserted through the hole 17e on the left side of the support panel 17 and screwed into the nut embedded in the hole 8c on the left side of the support frame 8, and the fixing bolt 24b is inserted through the hole 17e on the right side of the support panel 17 and screwed into the nut embedded in the hole 8c on the left side of the support frame 8, thereby temporarily fixing the support panel 17 to the support frame 8. Finally, the base plate 13 of the panel fixing bracket 12 is moved back and forth, the arm plate 15 and the intermediate panel 16 are rotated around the shaft bolt 27, and the support panel 17 is adjusted to be vertical, the panel fixing bracket 12 is fixed to the upper surface of the erecting structure 9, the arm plate 15 is fixed to the panel fixing bracket 12 and the intermediate panel 16, and the support panel 17 is fixed to the support frame 8. In this way, as shown in Figures 1 to 5, the battery storage base 1 is installed on the foundation concrete surface 2.

[0041] As described above, in the battery installation base 1, base blocks 3 and 4 are fixed to the foundation concrete surface 2 by block fixing brackets 5 and 6, the mounting frame 7 is fixed to base blocks 3 and 4 by connecting bolts 22a and 22b, the support frame 8 is fixed to base blocks 3 and 4 by connecting bolts 23a and 23b, the raising frame 9 is fixed to the upper surface of the support frame 8 by connecting brackets 10 and 11, the panel fixing bracket 12 is fixed to the upper surface of the raising frame 9, and the intermediate panel 16 is fixed to the panel fixing bracket 12 via the arm plate 15. The back of the support panel 17 is fixed to the intermediate panel 16, and an engagement plate 18 is attached to the front of the support panel 17. In this state, the battery 40 is placed on the mounting frame 7, and the back of the battery 40 is attached to the engagement plate 18 and fixed in place. Therefore, even if a large force acts on the battery 40 from the front horizontal direction or if it is subjected to lateral shaking due to an earthquake, the part that fixes the back of the battery 40 will not deform or break, preventing the battery 40 from being released from its fixation. Thus, the battery 40 can be installed even in places without building walls.

[0042] [Other embodiments of battery storage units] Next, another embodiment of the battery storage stand of the present invention will be described. Base blocks 3 and 4 may be placed on the ground instead of on the foundation concrete surface 2. Figure 10(a) is a perspective view showing the ground on which base blocks 3 and 4 are placed, and Figure 10(b) is a perspective view showing the base blocks 3 and 4 placed on the ground. In the diagram, 50 is the ground, 50p is the drop hole, 51 is the concrete body, and 51a and 51b are the holes. As shown in Figure 10(a), when the base blocks 3 and 4 are placed on the ground 50, the ground 50 is in contact with the front of the concrete body 51, and a drop hole 50p is dug in the ground 50 for dropping the base blocks 3 and 4 into. The concrete body 51 is the foundation on which the building's base rests, and it protrudes several tens of centimeters upward from the ground 50. Holes 51a and 51b are provided at predetermined positions on the front surface (the rising surface of the building's foundation) of the concrete body 51, and anchor bolts (described later) are driven into the holes 51a and 51b. As shown in Figure 10(b), the base blocks 3 and 4 are dropped into the recessed holes 50p so that their back surfaces are in contact with the front surface of the concrete body 51, and the top surfaces of the base blocks 3 and 4 are at the same height as the ground 50. In this case, the block fixing brackets 5 and 6 used to secure the base blocks 3 and 4 to the concrete surface 2 are unnecessary. Note that when placing base blocks 3 and 4 on the ground at 50, you can place base blocks 3 and 4 directly on the ground at 50 without digging a drop hole at 50p.

[0043] Figure 11(a) is a perspective view showing the mounting frame 7, support frame 8, and raising frame 9 fixed on the base blocks 3 and 4. Figure 11(b) is a front view thereof, and Figure 11(b) is a right side view thereof. In the figures, 52a and 52b are nuts. In the same manner as when the base blocks 3 and 4 are fixed to the concrete surface 2, the mounting frame 7 is fixed to the upper surface of the base blocks 3 and 4 with connecting bolts 22a and 22b, the support frame 8 is fixed to the upper surface of the base blocks 3 and 4 with connecting bolts 23a and 23b, and the connecting fittings 10 and 11 are fixed to the upper surface of the support frame 8, and the erection unit 9 and the connecting fittings 10 and 11 are fixed with fixing bolts 25a and 25a. In this state, anchor bolts (not shown), such as all-purpose anchors, grip anchors, and chemical anchors, are inserted through the elongated holes 10c and 11c on the back of the connecting fittings 10 and 11, driven into the holes 51a and 51b on the front of the concrete body 51, and nuts 52a and 52b are screwed onto the heads of the anchor bolts protruding from the elongated holes 10c and 11c. As a result, the support frame 8 and the erection structure 9 are fixed to the front of the concrete body 51 via the connecting fittings 10 and 11. Then, in the same manner as when the base blocks 3 and 4 were fixed to the foundation concrete surface 2, the panel fixing bracket 12 is fixed to the upper surface of the erected structure 9, the arm plate 15 is fixed to the panel fixing bracket 12 and the intermediate panel 16, the support panel 17 is fixed to the intermediate panel 16, the engagement plate 18 is attached to the support panel 17, and the support panel 17 is fixed to the support frame 8. In this manner, when the base blocks 3 and 4 are placed on the ground 50 (recessed hole 50p) instead of the foundation concrete surface 2, the base blocks 3 and 4 are not fixed to the ground 50 (recessed hole 50p). However, the support frame 8 and the erecting body 9 fixed to the base blocks 3 and 4 are fixed to the concrete body 51 by connecting fittings 10 and 11, nuts 52a and 52b, and anchor bolts. Even if a large force acts on the battery 40 from the front horizontal direction or if lateral shaking occurs due to an earthquake, the support frame 8 that fixes the battery 40 via the support panel, etc., will not move and shift its position, and the part that fixes the back of the battery 40 will not deform or break, preventing the battery 40 from being released.

[0044] When the battery storage stand of the present invention is placed on a foundation concrete surface (the upper surface of concrete embedded in the ground that forms the foundation of a building, etc.), the base blocks 3 and 4 may be omitted, and the mounting frame 7 and support frame 8 may be placed on the foundation concrete surface. In this case, the concrete foundation surface on which the mounting frame 7 and the support frame 8 are placed becomes the installation surface of the present invention. Figure 12(a) is a perspective view of the foundation concrete surface on which the mounting frame 7 and support frame 8 are placed, and Figure 12(b) is a perspective view of the state in which the mounting frame 7, support frame 8 and erection frame 9 are fixed on the foundation concrete surface. In the figures, 2' is the foundation concrete surface, and 2a1', 2a2', 2b1', and 2b2' are holes. As shown in Figure 10(a), when the mounting frame 7 and the support frame 8 are placed on the foundation concrete surface 2', the foundation concrete surface 2' is assumed to be in contact with the concrete body 51. The foundation concrete surface 2' has holes 2a1', 2b1', 2a2', and 2b2' at predetermined positions, and anchor nuts that screw into connecting bolts 22a, 22b, 23a, and 23b are driven into the holes 2a1', 2b1', 2a2', and 2b2'. The mounting frame 7 is fixed to the foundation concrete surface 2' by inserting connecting bolts 22a and 22b through holes 7a and 7b in the mounting frame 7 and screwing them into anchor nuts driven into holes 2a1' and 2b1' in the foundation concrete surface 2'. Furthermore, the support frame 8 is fixed to the foundation concrete surface 2' by inserting connecting bolts 23a and 23b through the holes 10a1 and 11b1 of the connecting fittings 10 and 11 and the through holes 8a and 8b of the support frame 8, and screwing them into anchor nuts driven into the holes 2a2' and 2b2' of the foundation concrete surface 2'. The fixing of the connecting fittings 10 and 11 to the concrete body 51 is the same as when the base blocks 3 and 4 shown in Figures 10 and 11 are placed on the ground 50 (recessed hole 50p) instead of the concrete surface 2, and the mounting and fixing of the panel fixing fittings 12, arm plate 15, intermediate panel 16, support panel 17, and engaging plate 18 is the same as when the mounting frame 7 and support frame 8 are fixed to the base blocks 3 and 4.

[0045] [Battery mounting stands with different methods for securing the battery to the back of the battery] Figure 13 is a perspective view showing the configuration of a battery mounting base with a different battery rear fixing means from battery mounting base 1, Figure 14 is a plan view of the battery mounting base shown in Figure 13, Figure 15 is a front view of the battery mounting base shown in Figure 13, Figure 16 is a right side view of the battery mounting base shown in Figure 13, Figure 17 is a rear view of the battery mounting base shown in Figure 13, and Figure 18 is an exploded perspective view of the battery mounting base shown in Figure 13. In the diagram, 1' is the battery mounting base, 3a3 and 4b4 are holes, 60L is the left support panel, 60R is the right support panel, 60a, 60b, 60c, 60d, and 60e are holes, 61 is the upper angle, 62 is the middle angle, 63 is the lower angle, 64 is the reinforcing block, 65 is the bumper, 70 and 71 are connecting fittings, 70a1, 70a2, 71b1, and 71b2 are holes, 70c and 71c are elongated holes, 80a, 80b, 81a, and 81b are fixing bolts, and 82a and 82b are nuts. Components of the battery mounting base 1 shown in Figures 1 to 12 are denoted by the same reference numerals. As shown in the figure, the battery mounting base 1' consists of a mounting frame 7, a support frame 8, a left support panel 60L, a right support panel 60R, an upper angle 61, a middle angle 62, a lower angle 63, a reinforcing block 64, a bumper 65, connecting fittings 70, 71, etc. In other words, the battery mounting base 1' is similar to the battery mounting base 1 in that it has a mounting base 7 and a support base 8 that are placed on the base blocks 3 and 4, but it differs from the battery mounting base 1 in that it has a structure that supports and fixes the back of the battery 40. In the battery mounting base 1', instead of the raised support 9, panel fixing brackets 12, intermediate panel 16, support panel 17 etc. of the battery mounting base 1, the left support panel 60L, right support panel 60R, upper angle 61, middle angle 62, lower angle 63, reinforcing block 64, bumper 65 etc. are used.

[0046] The left support panel 60L and the right support panel 60R are symmetrical metal or plastic panels with an L-shaped cross-section that support the back of the battery 40, and correspond to the support panel 17 of the battery mounting base 1. The front of the left support panel 60L is provided with two holes 60a and 60c, one at the top and one at the bottom, and the front of the right support panel 60R is also provided with two holes 60b and 60d, one at the top and one at the bottom. Then, similar to the support panel 17 of the battery mounting base 1, the upper plate 18U and lower plate 18S of the engaging plate 18 that engages with the battery 40 are placed against the front of the left support panel 60L and the right support panel 60R, so that the elongated holes 18a and 18b of the upper plate 18U overlap with the holes 60a and 60b, and the elongated holes 18c and 18d of the lower plate 18S overlap with the holes 60c and 60d, and the tightening bolts 33a, 33b, 33c, and 33d are inserted through the elongated holes 18a and 60a, 18b and 60b, 18c and 60c, and 18d and 60d respectively, and the tightening nuts 34a, 34b, 34c, and 34d are screwed onto the tightening bolts. As a result, the engagement plate 18 is attached to the front of the left support panel 60L and the right support panel 60R. Furthermore, a hole 60e is provided near the lower end of the right side of the right support panel 60R, and a similar hole 60e is also provided near the lower end of the right side of the left support panel 60L. The upper angle 61, middle angle 62, and lower angle 63 are metal or plastic angles with an L-shaped cross-section, and are attached to the upper, middle, and lower parts of the back of the left support panel 60L and the right support panel 60R, respectively, by welding, screws, adhesive, etc., connecting the left support panel 60L and the right support panel 60R from left to right. The left support panel 60L, the right support panel 60R, the upper angle 61, the middle angle 62, the lower angle 63, etc., form a box-shaped frame, which constitutes the fixed frame of the present invention. The reinforcing block 64 is a resin block that is fixed to the back of the left support panel 60L and the right support panel 60R directly below the lower angle 63 using screws, adhesive, etc., to prevent the box-shaped frame from deforming when subjected to external forces. The bumper 65 is a rod-shaped body made of resin with a roughly semicircular cross-section, and is attached to the rear side of the left support panel 60L and the right support panel 60R so as to protrude outward from the upper angle 61. This bumper 65 is designed to prevent damage to a building wall even if the installed left support panel 60L and right support panel 60R sway back and forth due to an earthquake or other event, causing their upper ends to collide with the wall of a nearby building.

[0047] When installing the battery storage stand 1', as in other embodiments of the battery storage stand 1 shown in Figure 10, etc., base blocks 3 and 4 are placed on the foundation concrete surface 2 or ground 50 that is in contact with the concrete body 51 (the figure shows the case where base blocks 3 and 4 are placed on ground 50 without a recess hole 50p), the mounting frame 7 is placed on the upper surface of the base blocks 3 and 4 and fixed with connecting bolts 22a and 22b, and the support frame 8 is placed on the upper surface of the base blocks 3 and 4 and fixed with connecting bolts 23a and 23b. In this case, unlike the battery mounting base 1, the connecting fittings 10 and 11 are not used, and the connecting bolts 23a and 23b are inserted through the through holes 8a and 8b of the support frame 8 without going through the holes 10a1 and 11b1 of the connecting fittings 10 and 11. Furthermore, unlike battery mounting base 1, battery mounting base 1' has connecting fittings 70 and 71 positioned on the left and right sides of the support frame 8, with the left support panel 60L and right support panel 60R in between. The connecting fittings 70 and 71 are fittings consisting of three surfaces (bottom, side, and back), similar to the connecting fittings 10 and 11. The bottom and side surfaces are provided with holes 70a1, 70a2, 71b1, and 71b2, while the back surface is provided with elongated holes 70c and 71c. On the upper surfaces of the base blocks 3 and 4, where the connecting fittings 70 and 71 are placed, holes 3a3 and 4b4 are provided at positions where the holes 70a1 and 71b1 overlap, and nuts that engage with fixing bolts are embedded in holes 3a3 and 4b4.

[0048] The connecting fittings 70 and 71, positioned on the upper surfaces of the base blocks 3 and 4, are then fixed to the base blocks 3 and 4, the support frame 8, the left support panel 60L, the right support panel 60R, and the concrete body 51 using fixing bolts 80a, 80b, 81a, 81b and nuts 82a, 82b. Specifically, the fixing bolt 80a is inserted through the hole 70a1 of the connecting fitting 70 and screwed with a nut embedded in the hole 3a3 of the base block 3, and the fixing bolt 81a is inserted through the hole 70a2 of the connecting fitting 70 and a hole provided near the lower end of the left side surface of the left support panel 60L and screwed with a nut embedded in the hole on the left side surface of the support frame 8. Furthermore, an anchor bolt (not shown) is inserted through the elongated hole 70c of the connecting fitting 70 and driven into the hole 51a on the front of the concrete body 51, and a nut 82a is screwed onto the head of the anchor bolt protruding from the elongated hole 70c. As a result, the base block 3, support frame 8, left support panel 60L, and concrete body 51 are fixed to each other via the connecting fitting 70. Similarly, the fixing bolt 80b is inserted through the hole 71b1 of the connecting fitting 71 and screwed with a nut embedded in the hole 4b4 of the base block 4, and the fixing bolt 81b is inserted through the hole 71b2 of the connecting fitting 71 and the hole 60e provided near the lower end of the left side of the right support panel 60R and screwed with a nut embedded in the hole 8c on the right side of the support frame 8. Furthermore, an anchor bolt (not shown) is inserted through the elongated hole 71c of the connecting fitting 71 and driven into the hole 51b on the front of the concrete body 51, and a nut 82a is screwed onto the head of the anchor bolt protruding from the elongated hole 71c. As a result, the base block 4, support frame 8, right support panel 60R, and concrete body 51 are fixed to each other via the connecting fitting 71.

[0049] Figure 19 is a rear view of the battery mounting base 1' when a rear block is used instead of the middle angle 62, lower angle 63, and reinforcing block 64 that connect the left support panel 60L and the right support panel 60R. In the figure, 90, 91, and 92 are rear blocks, and 93a, 93b, 94a, 94b, 95a, and 95b are fixing bolts. The rear blocks 90, 91, and 92 are rectangular concrete blocks with the same width as the support frame 8. They have through holes that penetrate from the top to the bottom at the same positions as the support frame 8, and the left and right sides have holes identical to the holes 8c on the left and right sides of the support frame 8, into which nuts are embedded. When using the rear blocks 90, 91, and 92, holes are provided on the sides of the left support panel 60L and the right support panel 60R in positions that overlap with the holes on the sides of the rear blocks 90, 91, and 92, and the support frame 8 uses nutted connecting bolts instead of connecting bolts 23a and 23b. These rear blocks 90, 91, and 92 are stacked on top of the support frame 8, and nutted connecting bolts are inserted through the through holes of the rear blocks 90, 91, and 92. The nutted connecting bolt inserted into rear block 90 is screwed onto the nut on the head of the nutted connecting bolt inserted into the support frame 8, and the nutted connecting bolts inserted through the through holes of each rear block 90, 91, and 92 are connected to each other, and the rear blocks 90, 91, and 92 are fixed to the top of the support frame 8. Then, the fixing bolts 93a, 94a, and 95a are inserted through holes provided on the side of the left support panel 60L and screwed into nuts embedded in holes provided on the left side of the rear blocks 90, 91, and 92. This fixes the side of the left support panel 60L to the left side of the rear blocks 90, 91, and 92. Furthermore, fixing bolts 93b, 94b, and 95b are inserted through holes provided in the right support panel 60R and screwed into nuts embedded in holes provided on the right side of the rear blocks 90, 91, and 92. This fixes the side of the right support panel 60R to the right side of the rear blocks 90, 91, and 92. In this way, the left support panel 60L and the right support panel 60R are connected by rear blocks 90, 91, and 92 fixed to the upper surface of the support frame 8, resulting in a stronger connection between the left support panel 60L and the right support panel 60R compared to when they are connected by middle angle 62, lower angle 63, and reinforcing block 64.

[0050] As described above, in the battery installation platform 1', the mounting frame 7 and the support frame 8 are placed on the upper surface of the base blocks 3 and 4 which are placed on the foundation concrete surface 2 or the ground 50, the mounting frame 7 is fixed to the base blocks 3 and 4 by connecting bolts 22a and 22b, the support frame 8 is fixed to the base blocks 3 and 4 by connecting bolts 23a and 23b, the left support panel 60L and the right support panel 60R are connected by upper angle 61, middle angle 62 and lower angle 63 to form a box-shaped frame which is reinforced by reinforcing block 64, or reinforced by back blocks 90, 91 and 92, and the left support panel 60L and the right support panel 60R are connected by connecting fittings 70 The battery 40 is fixed to the base blocks 3 and 4, the support frame 8, and the concrete body 51 via 71, and engaging plates 18 are attached to the front of the left support panel 60L and the right support panel 60R. In this state, the battery 40 is placed on the mounting frame 7, and the back of the battery 40 is attached to the engaging plates 18 and fixed in place. Thus, even if a large force is applied to the battery 40 from the front horizontal direction or if lateral shaking occurs due to an earthquake, the part that fixes the back of the battery 40 will not deform or break, preventing the battery 40 from being released from its fixation, and the battery 40 can be installed even in places without building walls. [Industrial applicability]

[0051] The battery mounting base and battery mounting structure of the present invention prevent deformation or damage to the fixing part of the battery, even if excessive force is applied to the part that fixes the battery during installation, thus preventing the battery from being released. This allows for battery installation even in locations without building walls, and can be used to install household batteries on building foundations, the ground, etc. [Explanation of Symbols]
