[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0031] First, in the related art, the junction box is directly fixed to the bottom plate of the container by bolts. However, because the bottom plate of the container is relatively thin, the junction box is prone to pulling on the bolts and the bottom plate of the container under vibration conditions (such as during transportation), causing the bottom plate of the container to deform at the fixed position, thereby resulting in the fixing of the junction box being insufficiently stable.

[0032] In order to solve the above technical problems, such as Figure 1 As shown, an embodiment of the present invention provides a combiner cabinet fixing structure 100 , which includes a combiner cabinet 10 , a fixing base plate 20 and a positioning assembly 30 .

[0033] The junction box 10 mentioned in this application is a device for concentrating currents from different directions into one place and transmitting them to downstream equipment through suitable wires or cables. For example, the junction box 10 is used in an energy storage container, which generally also includes a battery cluster. The junction box 10 gathers the current from the battery cluster and transmits the current to the downstream equipment through wires. The junction box 10 mainly includes a cabinet body and a plurality of conductor bars installed in the cabinet body. Of course, some junction boxes 10 also integrate components such as power distribution and UPS (Uninterruptible Power Supply). In short, the specific structure of the junction box 10 is not limited here, and it can be flexibly designed according to needs in actual application.

[0034] like Figure 2 As shown, in this embodiment, the overall shape of the combiner cabinet 10 is a rectangular parallelepiped, and a plurality of column feet 11 are protruding from the bottom surface 14 of the combiner cabinet 10. Figure 2 In the structure shown, there are four column feet 11, which are respectively located at the four corners of the combiner cabinet 10. Of course, the column feet 11 can also be set to other numbers, such as two, three, five, six, eight, etc.

[0035] In addition, the shape, length, etc. of the column base 11 can be flexibly designed according to needs. For example, in the present embodiment, the column base 11 is a square column. In other embodiments, the column base 11 can also be cylindrical, elliptical, or other polygonal shapes (such as triangular prism, pentagonal prism, hexagonal prism, etc.).

[0036] In this embodiment, the column foot 11 is in a hollow tubular shape, which can reduce the weight of the combiner cabinet 10 . In other embodiments, the column foot 11 can also be solid, which can improve the structural strength of the column foot 11 .

[0037] One of the fixing column 21 and the column foot 11 is provided with a fixing hole 211 , and the other is inserted into the fixing hole 211 one by one.

[0038] Specifically, such as Figure 4 As shown, in one embodiment, a plurality of fixing columns 21 are provided on the fixed base plate 20, each of which has fixing holes 211 defined therein, and the plurality of column feet 11 are inserted one by one into the fixing holes 211. Specifically, because the combiner cabinet 10 is intended to be installed in an energy storage container, the fixed base plate 20 can be formed by the bottom plate of the energy storage container. Alternatively, in other embodiments, the fixed base plate 20 is a base plate independent of the energy storage container and specifically used to fix the combiner cabinet 10. When fixing the combiner cabinet 10 in the energy storage container, the fixed base plate 20 can be first fixed to the bottom plate of the energy storage container, and then the combiner cabinet 10 can be fixed to the fixed base plate.

[0039] like Figure 4 As shown, a plurality of fixing columns 21 are provided on the fixed base plate 20. The number of fixing columns 21 is the same as the number of column feet 11. For example, if there are four column feet 11, the number of fixing columns 21 is also four. The fixing columns 21 can be integrally formed with the fixed base plate 20 or welded to the fixed base plate 20. Fixing holes 211 are provided in the fixing columns 21. The fixing holes 211 extend along the axial direction of the fixing columns 21. The size and shape of the fixing holes 211 are adapted to match the column feet 11. For example, if the column feet 11 are square columns, the fixing holes 211 are adapted to be square holes.

[0040] When assembling, you can refer to Figure 1The multiple column feet 11 of the combiner cabinet 10 are inserted into the multiple fixing holes 211 one by one. It can be understood that compared with the combiner cabinet 10 being directly fixed to the thinner container bottom plate by bolts, when the combiner cabinet 10 is inserted into the fixing holes 211 of the fixing columns 21 through the column feet 11, the connection thickness between the combiner cabinet 10 and the fixed bottom plate 20 is increased, so that the combiner cabinet 10 is not easy to pull and deform the fixed bottom plate 20 under vibration conditions, thereby improving the fixing stability of the combiner cabinet 10.

[0041] Alternatively, in another embodiment, the fixing holes 211 are provided on the column base 11. During assembly, the plurality of column bases 11 are sleeved onto the outside of the plurality of fixing columns 21 one by one through the fixing holes 211 (i.e., the fixing columns 21 are inserted into the column base 11). This can also increase the connection thickness between the junction box 10 and the fixed base plate 20.

[0042] Furthermore, in order to improve the fixing stability of the combiner cabinet 10, please combine Figure 1 、 Figure 6 and Figure 7 The junction cabinet fixing structure 100 of the present application also includes a positioning assembly 30, which includes a first positioning member 31 and a second positioning member 32, wherein the first positioning member 31 passes through the side wall of the fixing column 21 along the first direction and penetrates into the column foot 11, and the second positioning column passes through the side wall of the fixing column 21 along the second direction and penetrates into the column foot 11, and the first direction and the second direction are perpendicular to each other.

[0043] Specifically, if Figure 6 As shown, the first positioning member 31 and the second positioning member 32 are rod-shaped as a whole. For example, the first positioning member 31 and the second positioning member 32 can be positioning pins, positioning bolts, etc. Figure 1 As indicated in the direction, the first direction is the X-axis direction, the second direction is the Y-axis direction, and the axial direction of the column foot 11 or the fixing column 21 is the Z-axis direction, so the first direction and the second direction are perpendicular to each other.

[0044] Taking the fixing hole 211 provided in the fixing column 21 as an example, after the column foot 11 is inserted into the fixing hole 211 of the fixing column 21, for each fixing column 21 and the column foot 11 corresponding thereto, the first positioning member 31 penetrates the side wall of the fixing column 21 along the X-axis direction and penetrates the column foot 11, and the second positioning member 32 penetrates the side wall of the fixing column 21 along the Y-axis direction and penetrates the column foot 11.

[0045] It can be understood that because the first positioning member 31 and the second positioning member 32 simultaneously penetrate the side wall of the fixing column 21 and the entire column base 11, the column base 11 can be restricted from upwardly disengaging from the fixing hole 211, that is, the movement of the column base 11 in the Z-axis direction is restricted. Moreover, because the first direction and the second direction are perpendicular to each other, the first positioning member 31 and the second positioning member 32 respectively restrict the movement of the column base 11 in the X-axis direction and the Y-axis direction, that is, the movement of the column base 11 in the X-axis, Y-axis and Z-axis directions is restricted, which can make the fixation of the junction cabinet 10 more stable.

[0046] Optionally, in one embodiment, as Figure 3 As shown, the column foot 11 has a first threaded hole 121 and a second threaded hole 131 extending therethrough. The first threaded hole 121 extends in a first direction, i.e., along the X-axis, and the second threaded hole 131 extends in a second direction, i.e., along the Y-axis. The first positioning member 31 and the second positioning member 32 are both threaded connectors, specifically bolts, with the first positioning member 31 being threadedly engaged within the first threaded hole 121, and the second positioning member 32 being threadedly engaged within the second threaded hole 131.

[0047] It can be understood that in this embodiment, the hole on the column foot 11 for the first positioning member 31 to pass through is the first threaded hole 121, and the hole on the column foot 11 for the second positioning member 32 to pass through is the second threaded hole 131. Therefore, the first positioning member 31 and the second positioning member 32, while being inserted into the column foot 11, are also screwed into the first threaded hole 121 and the second threaded hole 131, respectively. This not only secures the first positioning member 31 and the second positioning member 32 to the column foot 11, preventing them from falling off the column foot 11 and the fixing column 21 under vibration conditions, but also facilitates the removal of the first positioning member 31 and the second positioning member 32, thereby facilitating the removal of the combiner cabinet 10 from the fixing base plate 20.

[0048] Furthermore, in one embodiment, please combine Figure 3 and Figure 9 The column foot 11 is hollow tubular, and a first stud 12 and a second stud 13 are fixed on the column foot 11. The first stud 12 extends along the first direction, and a first threaded hole 121 is provided in the first stud 12; the second stud 13 extends along the second direction, and a second threaded hole 131 is provided in the second stud 13.

[0049] Specifically, in this embodiment, the column foot 11 is hollow tubular, which reduces the weight of the combiner cabinet 10. To form the first threaded hole 121 and the second threaded hole 131 in the hollow tubular column foot 11, a first stud 12 and a second stud 13 are fixed to the column foot 11. Each of the first stud 12 and the second stud 13 is an oblong nut. The first stud 12 extends in a first direction and has the first threaded hole 121 formed therein. The second stud 13 extends in a second direction and has the second threaded hole 131 formed therein. This ensures that the first threaded hole 121 and the second threaded hole 131 are formed in the column foot 11 while reducing the weight of the combiner cabinet 10.

[0050] It should be noted that the first stud 12 and the second stud 13 can be fixed to the column foot 11 by means of clamping, welding, bonding, etc.

[0051] Optionally, in one embodiment, as Figure 8 or Figure 9 As shown, the first positioning member 31 and the second positioning member 32 are both bolts, and both include a connected screw 301 and a screw head 302. The screw 301 passes through the side wall of the fixing column 21 and is screwed to the column foot 11. The screw head 302 abuts against the outside of the side wall of the fixing column 21, and a spring washer 33 and / or a flat washer 34 are sandwiched between the screw head 302 and the side wall of the fixing column 21.

[0052] Among them, the spring washer 33 is made of elastic material, which can effectively relieve vibration and impact force, thereby increasing the anti-loosening performance of the first positioning member 31 and the second positioning member 32, making the first positioning member 31 and the second positioning member 32 not easy to fall off, thereby ensuring the stable fixation of the junction box 10.

[0053] The flat washer 34 is made of a hard material, which can evenly distribute the fastening force of the first positioning member 31 and the second positioning member 32 so that the first positioning member 31 and the second positioning member 32 can be more firmly and stably connected to the column foot 11, thereby ensuring the installation stability of the combiner cabinet 10.

[0054] Optionally, in one embodiment, as Figure 5 As shown, the side wall of the fixing column 21 is provided with a first through hole 212 and a second through hole 213. Figure 1 and Figure 3 The first through hole 212 is arranged corresponding to the first threaded hole 121, the first positioning member 31 passes through the first through hole 212 and is screwed into the first threaded hole 121, the second through hole 213 is arranged corresponding to the second threaded hole 131, the second positioning member 32 passes through the second through hole 213 and is screwed into the second threaded hole 131; wherein, the first through hole 212 and the second through hole 213 are both waist-shaped holes.

[0055] It can be understood that in this embodiment, by making the first through hole 212 and the second through hole 213 on the fixing column 21 both waist-shaped holes, it is possible to avoid the situation where the holes are not accurately aligned due to processing errors, which makes it difficult for the bolts to penetrate and screw in.

[0056] Optionally, in one embodiment, a fixing hole 211 is provided in the fixing column 21, and an elastic member (not shown) is sandwiched between the outer peripheral wall of the column foot 11 and the inner peripheral wall of the fixing hole 211. Specifically, in this embodiment, to ensure that the column foot 11 can be smoothly inserted into the fixing hole 211, the column foot 11 and the fixing hole 211 are clearance-matched, and an elastic member is provided in the gap between the column foot 11 and the fixing hole 211. The elastic member may specifically be elastic cotton, elastic glue, etc., thereby providing a good buffering effect on the combiner cabinet 10 and reducing the degree of vibration transmitted to the combiner cabinet 10.

[0057] Alternatively, in another embodiment, a fixing hole 211 is defined within the column foot 11, and an elastic member is interposed between the outer circumferential wall of the fixing column 21 and the inner circumferential wall of the fixing hole 211. Specifically, in this embodiment, to ensure smooth insertion of the fixing column 21 into the fixing hole 211, the fixing column 21 and the fixing hole 211 are clearance-matched, and an elastic member, specifically elastic cotton, elastic glue, etc., is disposed in the gap between the fixing column 21 and the fixing hole 211. This provides a good buffering effect on the combiner cabinet 10, reducing the degree of vibration transmitted to the combiner cabinet 10.

[0058] Optionally, in one embodiment, as Figure 4 As shown, multiple fixing columns 21 are spaced apart along the circumference of the combiner cabinet 10, with a crossbeam 22 connecting two adjacent fixing columns 21. Specifically, in this embodiment, the combiner cabinet 10 has an overall rectangular parallelepiped structure. Four column feet 11 are provided at the bottom of the combiner cabinet 10, located at the four corners of the combiner cabinet 10. There are also four fixing columns 21, each corresponding to one of the four column feet 11. A crossbeam 22 connects every two adjacent fixing columns 21 along the circumference of the combiner cabinet 10.

[0059] It can be understood that by connecting the crossbeam 22 between two adjacent fixing columns 21 , the multiple fixing columns 21 can support each other, thereby improving the overall structural strength and facilitating more stable fixing and support of the combiner cabinet 10 .

[0060] Optionally, in one embodiment, as Figure 1 As shown, the combiner cabinet 10 has a bottom surface 14 facing the fixed base plate 20, and the column foot 11 protrudes from the bottom surface 14 toward the fixed base plate 20. Figure 4 and Figure 5As shown, the depth of the fixing hole 211 is greater than the length of the column foot 11. The crossbeam 22 has a support surface 221 facing the bottom surface 14. The fixing column 21 has an upper end surface 214 facing the bottom surface 14. The support surface 221 is flush with the upper end surface 214, and the bottom surface 14 is also supported on the support surface 221. In other words, in addition to connecting two adjacent fixing columns 21 to enhance the overall structural strength, the crossbeam 22 also supports the combiner cabinet 10, increasing the support area of the fixed base plate 20 for the combiner cabinet 10, thereby ensuring a more stable installation of the combiner cabinet 10 on the fixed base plate 20.

[0061] Optionally, in one embodiment, as Figure 4 As shown, a relief recess 222 is provided on the side of the crossbeam 22 facing away from the combiner cabinet 10. The relief recess 222 is used to pass the wires in the combiner cabinet 10. Specifically, a combiner cabinet 10 generally contains multiple wires, some of which need to pass through the bottom of the combiner cabinet 10 to connect to other equipment. Because the crossbeam 22 is connected between two adjacent fixing columns 21 in this embodiment, the crossbeam 22 may hinder the extension of the wires. Therefore, the relief recess 222 is also provided on the side of the crossbeam 22 facing away from the combiner cabinet 10 to facilitate the wires to pass through the relief recess 222 and connect to other equipment.

[0062] Optionally, in one embodiment, as shown in FIG5 , the fixing column 21 is a square tube, and is fixed with adjacent connecting side walls 215 and two adjacent positioning side walls 216. Figure 4 The connecting sidewall 215 is connected to a crossbeam 22, the positioning sidewall 216 is penetrated by a first positioning member 31 or a second positioning member 32, and a reinforcing rib 23 is connected between the positioning sidewall 216 and the fixed base plate 20. In other words, in this embodiment, each sidewall of the fixing column 21 is provided with a reinforcing structure (i.e., a crossbeam 22 and a reinforcing rib 23), which improves the structural strength of the fixing column 21 and further secures the combiner cabinet 10.

[0063] An embodiment of the present application further provides an energy storage container, which includes the combiner cabinet fixing structure 100 of any of the above embodiments. Since the energy storage container adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described one by one here.

[0064] The above is a detailed introduction to the embodiments of the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, based on the idea of the present invention, there will be changes in the specific implementation methods and application scope.
