[0042] In the related art, household energy storage boxes are mostly of assembled or integrated structures. Among them, the integrated structure connects each box panel by welding to form a complete energy storage box, which cannot be disassembled and is not conducive to transportation. The assembled structure separates each box panel. During assembly, each box panel needs to be assembled and connected by screws, with many assembly steps and a large on-site assembly workload.

[0043] Based on the above problems and concepts, please combine Figures 1 to 19 As shown, the present utility model provides an energy storage box 100 for placing batteries. The energy storage box 100 includes a box body and a battery fixing rack 7. The box body includes a back panel 1, a top panel 2, a first side panel 3, a second side panel 4, a bottom panel 5, and a door panel 6. The top panel 2, the first side panel 3, the second side panel 4, and the bottom panel 5 are respectively rotatably connected to the back panel 1, and the door panel 6 is detachably connected to the first side panel 3 and the second side panel 4; the battery fixing rack 7 is arranged on the first side panel 3 and the second side panel 4; wherein, the energy storage box 100 has an assembled state and a folded state; in the folded state, the top panel 2, the first side panel 3, the second side panel 4, the bottom panel 5 are in abutting connection with the back panel 1; in the assembled state, the top panel 2, the first side panel 3, the second side panel 4, the bottom panel 5, and the door panel 6 enclose to form a cavity, and the battery fixing rack 7, the first side panel 3, and the back panel 1 enclose to form a placement cavity.

[0044] In this embodiment, when the energy storage box 100 needs to be transported, first remove the door panel 6 from the first side plate 3 and the second side plate 4, and then rotate the top plate 2, the first side plate 3, the second side plate 4, and the bottom plate 5 around the back plate 1 so that the top plate 2, the first side plate 3, the second side plate 4, and the bottom plate 5 are stacked on the back plate 1, enabling the energy storage box 100 to enter the folded state, thereby reducing the occupied space of the energy storage box 100 and improving the transportation efficiency. When the energy storage box 100 needs to be used, rotate the top plate 2, the first side plate 3, the second side plate 4, the bottom plate 5, and the door panel 6 back to their original positions, then assemble the movable ends, and then install the door panel 6 on the first side plate 3 and the second side plate 4 to complete the assembly of the energy storage box 100, enabling the energy storage box 100 to enter the assembled state. Battery fixing frames 7 are also provided on the first side plate 3 and the second side plate 4. After the energy storage box 100 is assembled, the top plate 2, the first side plate 3, the second side plate 4, the bottom plate 5, and the door panel 6 enclose a cavity to protect the battery located in the cavity. The battery fixing frames 7 on the first side plate 3 and the second side plate 4, the first side plate 3, the second side plate 4, and the back plate 1 enclose a placement cavity. In this way, the cavity can be partitioned by the battery fixing frames 7 to facilitate the neat arrangement and heat dissipation of the batteries.

[0045] In actual implementation, in the combined state, the door panel 6 can be removed from the first side plate 3 and the second side plate 4 to facilitate the placement of the battery. In the folded state, the door panel 6 can be stacked and transported together with the folded top plate 2, the first side plate 3, the second side plate 4, the bottom plate 5, and the back plate 1. It can be understood that battery fixing frames 7 are provided on both the first side plate 3 and the second side plate 4. The battery fixing frames 7 can include two groups and can be used to place batteries that meet the international 19-inch rack standard. The battery fixing frames 7 are welded to the first side plate 3 and the second side plate 4 by means of resistance welding or carbon dioxide shielded welding. The top plate 2, the first side plate 3, the second side plate 4, the bottom plate 5, the back plate 1, and the door panel 6 are produced by sheet metal bending process.

[0046] In an embodiment of the present utility model, as Figures 1 to 3 shown, the back plate 1 has a first surface 11 and a second surface 12 facing away from each other, and a first side, a second side, a third side, and a fourth side connected in sequence. The top plate 2 is rotatably connected to the first side, the first side plate 3 and the second side plate 4 are rotatably connected to the second side and the third side, and the bottom plate 5 is rotatably connected to the fourth side; in the folded state, the top plate 2 and the bottom plate 5 abut against the first surface 11, and the first side plate 3 and the second side plate 4 abut against the second surface 12.

[0047] In this embodiment, the back panel 1 has a first surface 11 and a second surface 12 facing away from each other. When the top panel 2, the first side panel 3, the second side panel 4, and the bottom panel 5 are rotated and folded relative to the back panel 1, the top panel 2 and the bottom panel 5 abut against the first surface 11, and the first side panel 3 and the second side panel 4 abut against the second surface 12. In this way, the difficulty of folding the energy storage box 100 can be reduced, and the battery fixing bracket 7 can be prevented from interfering with the folding. The top panel 2, the first side panel 3, the second side panel 4, and the bottom panel 5 are respectively rotatably connected to the first side, the second side, the third side, and the fourth side of the back panel 1. In this way, the top panel 2, the first side panel 3, the second side panel 4, and the bottom panel 5 can rotate around the back panel 1 from different directions to improve the folding efficiency of the energy storage box 100. It can be understood that in the folded state, the top panel 2 and the bottom panel 5 each occupy half of the first surface 11, and the first side panel 3 and the second side panel 4 each occupy half of the second surface 12 to ensure the size of the cavity.

[0048] In actual implementation, one side of the top panel 2, the first side panel 3, the second side panel 4, and the bottom panel 5 is rotatably connected to the back panel 1, and the other sides of the top panel 2, the first side panel 3, the second side panel 4, and the bottom panel 5 are installation sides for mutual combined installation to form the energy storage box 100.

[0049] In an embodiment of the present utility model, as Figure 4 and Figure 6 shown, a top panel rotating shaft 13 is provided on the first side, and the top panel 2 is provided with a top panel rotating shaft hole 21 corresponding to the top panel rotating shaft 13, and the top panel rotating shaft 13 passes through the top panel rotating shaft hole 21.

[0050] In this embodiment, the top panel 2 and the back panel 1 are rotatably connected through the rotational cooperation of the top panel rotating shaft 13 and the top panel rotating shaft hole 21. The top panel rotating shaft 13 on the first side is installed on the back panel 1 through a detachable connection method such as screws or snap-fit structures, so as to facilitate the replacement of the top panel rotating shaft 13.

[0051] In actual implementation, the back panel 1 is provided with an avoidance groove corresponding to the top panel rotating shaft 13, and the top panel rotating shaft 13 is arranged in the avoidance groove to facilitate the rotation of the top panel 2. The top panel rotating shaft hole 21 can be arranged on a mounting plate, and the mounting plate is installed on the top panel 2 through a detachable connection method such as screws or snap-fit structures. The mounting plate can be arranged in an L shape, and no specific limitation is made here.

[0052] In an embodiment of the present utility model, as Figure 4 and Figure 14 shown, the energy storage box 100 further includes a limiting diagonal brace 8. One end of the limiting diagonal brace 8 is rotatably connected to the back panel 1, and the top panel 2 is provided with a sliding groove 22, and the other end of the limiting diagonal brace 8 is slidably arranged in the sliding groove 22.

[0053] In this embodiment, when the top plate 2 rotates around the back plate 1, one end of the limiting diagonal brace 8 also rotates accordingly, and the other end of the limiting diagonal brace 8 also moves within the sliding groove 22. The sliding groove 22 has a first position close to the first side, a second position far from the second side, and a third position between the first end and the second end. When the energy storage box 100 is in the assembled state, the other end of the limiting diagonal brace 8 is located at the third position. When the top plate 2 rotates around the back plate 1 until it abuts against the back plate 1, the other end of the limiting diagonal brace 8 is located at the second position. When the energy storage box 100 changes from the folded state to the assembled state, the top plate 2 needs to be turned upwards. At this time, the other end of the limiting diagonal brace 8 is limited at the first position to keep the top plate 2 in the turned-up state, thus preventing the top plate 2 from accidentally turning downwards when the first side plate 3 and the second side plate 4 are opened and reset.

[0054] In actual implementation, the groove wall of the sliding groove 22 is provided with a depression corresponding to the first position. When the other end of the limiting diagonal brace 8 is located at the first position, the other end of the limiting diagonal brace 8 is limited within the depression. Optionally, the groove wall of the sliding groove 22 is also provided with depressions corresponding to the second position and the third position.

[0055] It can be understood that the sliding groove 22 is arranged on a mounting plate, and the mounting plate is connected to the top plate 2 through a detachable connection method such as screws or snap-fit structures.

The first rotating shaft 31 and the second rotating shaft 41 are respectively installed on the first side plate 3 and the second side plate 4 through detachable connection methods such as screws or snap-fit structures, so as to facilitate the replacement of the first rotating shaft 31 and the second rotating shaft 41.

[0058] In actual implementation, the first rotating shaft hole 14 or the second rotating shaft hole 15 can be arranged on a mounting piece, and the mounting piece is installed on the back plate 1 through a detachable connection method such as screws or snap-fit structures. The mounting piece can be arranged in an L shape, and no specific limitation is made here.

[0059] In an embodiment of the present utility model, as Figure 4 , Figure 13 andFigure 15 As shown, both the first side plate 3 and the second side plate 4 are provided with battery fixing brackets 7. The battery fixing bracket 7 is provided with a first mounting hole 71, and the back plate 1 is provided with a second mounting hole 16 corresponding to the first mounting hole 71. In the assembled state, the battery fixing bracket 7 and the back plate 1 are threadedly connected through the first mounting hole 71 and the second mounting hole 16.

[0060] In this embodiment, when the energy storage box 100 is converted from the folded state to the assembled state, the first side plate 3 and the second side plate 4 are rotated back to their original positions. At this time, the battery fixing brackets 7 on the first side plate 3 and the second side plate 4 abut against the back plate 1, and the first mounting holes 71 on the battery fixing brackets 7 are aligned with the second mounting holes 16 on the back plate 1. Bolts and nuts are used in cooperation or screws are passed through the first mounting hole 71 and the second mounting hole 16 to connect the battery fixing bracket 7 and the back plate 1, thereby relatively fixing the positions of the first side plate 3 and the back plate 1, and relatively fixing the positions of the second side plate 4 and the back plate 1. In this way, the battery fixing bracket 7 has two connection positions to prevent the first side plate 3 or the second side plate 4 from deforming due to the heavy weight of the battery.

[0061] In actual implementation, the battery fixing bracket 7 is arranged in an L shape. The battery fixing bracket 7 includes a first section and a second section that are vertically arranged. The first section is provided with the first mounting hole 71, and the second section is connected to the first side plate 3 or the second side plate 4 to form a placement cavity.

The top plate 2 is respectively provided with a first plug pin 23 and a second plug pin 24 corresponding to the first limiting hole 32 and the second limiting hole 42. In the assembled state, the first plug pin 23 is limited in the first limiting hole 32, and the second plug pin 24 is limited in the second limiting hole 42.

[0063] In this embodiment, when the box body is in the assembled state, the first plug pin 23 and the second plug pin 24 on the top plate 2 are respectively limited in the first limiting hole 32 of the first side plate 3 and the second limiting hole 42 of the second side plate 4 to relatively fix the positions of the top plate 2, the first side plate 3 and the second side plate 4, so that the top plate 2 is in a horizontal state and the top plate 2 is in a non-flippable state to prevent the top plate 2 from folding down or flipping up.

[0064] In actual implementation, when the energy storage box 100 is placed on a horizontal plane, the first bolt 23 and the second bolt 24 are respectively arranged on two sides of the top plate 2, the first limiting hole 32 and the second limiting hole 42 are respectively arranged at the tops of the first side plate 3 and the second side plate 4, the first bolt 23 and the second bolt 24 are arranged in the horizontal direction, and the first limiting hole 32 and the second limiting hole 42 are respectively arranged corresponding to the first bolt 23 and the second bolt 24, and no specific limitation is made here. The first bolt 23 and the second bolt 24 are arranged on the top plate 2 through elastic members. After the first side plate 3 and the second side plate 4 are assembled in place, the top plate 2 presses down, the first bolt 23 and the second bolt 24 respectively abut against the first side plate 3 and the second side plate 4 and retract inward until when the first bolt 23 and the second bolt 24 reach the first limiting hole 32 and the second limiting hole 42, the first bolt 23 and the second bolt 24 rebound, so that the first bolt 23 and the second bolt 24 are respectively limited in the first limiting hole 32 and the second limiting hole 42.

The bottom plate rotating shaft 17 on the third side is installed on the back plate 1 through a detachable connection method such as screws or a clamping structure, etc., so as to facilitate the replacement of the bottom plate rotating shaft 17.

[0067] In actual implementation, the back plate 1 is provided with an avoidance groove corresponding to the bottom plate rotating shaft 17, and the bottom plate rotating shaft 17 is arranged in the avoidance groove to facilitate the rotation of the bottom plate 5. The bottom plate rotating shaft hole 51 can be arranged on a mounting piece, and the mounting piece is installed on the bottom plate 5 through a detachable connection method such as screws or a clamping structure, etc. The mounting piece can be arranged in an L shape, and no specific limitation is made here.

[0071] In an embodiment of the present utility model, as Figure 4 , Figure 7 , Figures 15 to 19 shown, the first side plate 3 is provided with a door panel rotating shaft hole 34, the door panel 6 is provided with a door panel rotating shaft 61 corresponding to the door panel rotating shaft hole 34, the second side plate 4 is provided with a door panel lock 44, and the door panel 6 is provided with a lock hole 62 corresponding to the door panel lock 44; in the assembled state, the door panel rotating shaft 61 is inserted through the door panel rotating shaft hole 34.

[0072] In this embodiment, when the energy storage box 100 is in the assembled state, the door panel 6 and the first side plate 3 are rotationally connected through the rotation cooperation of the door panel rotating shaft 61 and the door panel rotating shaft hole 34. By rotating the door panel 6 around the door panel rotating shaft 61, the cavity can be opened or closed. It can be understood that the door panel lock 44 is movably arranged on the first side plate 3. By lifting the door panel lock 44 to align with the lock hole 62, when the lock hole 62 of the door panel 6 extends into the lock hole 62, the door panel lock 44 is pushed down to limit the door panel lock 44 in the lock hole 62 to lock the door panel 6.

[0073] In actual implementation, a buffer pad 63 can also be arranged on the door panel 6. When the door panel 6 is closed, the buffer pad 63 abuts against the second side plate 4 and / or the top plate 2 and / or the bottom plate 5 to reduce the collision between the door panel 6 and these plates and play a buffering role.

[0074] When the energy storage box 100 of the present application is converted from the folded state to the assembled state, first turn the bottom plate 5 outwards, then turn the top plate 2 upwards, and support the top plate 2 with the limiting diagonal brace 8. Then, sequentially open the first side plate 3 and the second side plate 4 from the folded state to the vertical state, and use screws to pass through the first fixing hole 33 and the third fixing hole 52 and the second fixing hole 43 and the fourth fixing hole 53 to fixedly connect the first side plate 3 and the second side plate 4. Then, use screws to pass through the first mounting hole 71 and the second mounting hole 16 to connect the battery fixing member and the back plate 1. Then, put down the top plate 2 in the upwardly turned state to make it in the horizontal state, insert the first pin 23 and the second pin 24 into the first limiting hole 32 and the second limiting hole 42 respectively to make the top plate 2 in a non-turnable state. Finally, insert the door plate rotating shaft 61 of the door plate 6 into the door plate rotating shaft hole 34 to complete the installation of the door plate 6. After putting the battery into the placement cavity, close the door plate 6, push the door plate lock 44 downwards, and limit the door plate lock 44 in the lock hole 62 to complete the locking of the door plate 6. It can be understood that the steps for converting the energy storage box 100 from the assembled state to the folded state can refer to the reverse operation of the above steps. The rotating shaft and rotating hole structures between the respective plates can be arranged in a consistent manner.

[0075] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
