[0039] Figure 1 and Figure 2 The energy storage system 10 in some embodiments of the utility model is shown, and the energy storage system 10 includes a plurality of energy storage cabinets for energy storage, and each energy storage cabinet includes a cabinet 1 and a wall-mounted device 2. The cabinet 1 is used to store energy storage units and related electrical components and devices. The wall-mounted device 2 is used to hang components or devices disposed outside the cabinet 1 on the cabinet 1.

[0040] like Figures 1 to 6 As shown, the cabinet 1 includes a base 11, a side stand assembly 12 and a side panel 13 arranged on the base 11, the side panel 13 has a first side 131 and a second side 132 facing oppositely, the side stand assembly 12 includes at least one column 121 arranged on the base 11 and at least two beams 122 connecting the columns 121, the beams 122 are parallel to each other, the beams 122 are connected to the columns 121, and the columns 121 and the beams are connected to the first side 131.

[0041] It can be understood that the base 11 plays a load-bearing role. The side stand assembly 12 is used to bear the weight and transfer the weight to the base 11. The side panel 13 plays a role in shielding and protecting the internal components of the cabinet 1; the number of side panels 13 can be configured to be multiple, and protection is provided from different positions by multiple side panels. The column 121 is perpendicular to the base 11. The vertical setting can avoid bending and deformation of the column 121, etc., and can improve the load-bearing capacity in the longitudinal direction. Each beam 122 is perpendicular to the column 121. The side panel 13 is plate-shaped as a whole, with the first side 131 facing the inside of the cabinet 1 and the second side 132 exposed to the outside of the cabinet 1.

[0042] It should be noted that the peripheral edge of the side plate 13 may be bent to form a folded edge, and the folded edge may be matched with the end of the cross beam 122 .

[0043] like Figure 2 and Figure 3As shown, the wall-mounted device 2 is located on the second side 132, and the wall-mounted device 2 includes an upper hanging beam 211, a lower hanging beam 212, at least one longitudinal hanging beam 213 and at least one wall-mounted component 22. The upper hanging beam 211 and the lower hanging beam 212 are parallel to each other, and both ends of each longitudinal hanging beam 213 are respectively connected to the upper hanging beam 211 and the lower hanging beam 212, and the wall-mounted component 22 is used to fix wall-mounted objects.

[0044] A wall hanging component 22 is provided on at least the upper hanging beam 211, the lower hanging beam 212 or the longitudinal hanging beam 213. Figure 3 and Figure 7 As shown, the upper hanging beam 211 and one of the cross beams 122 on the side plate 13 correspond to each other, and the lower hanging beam 212 and the other cross beam 122 on the side plate 13 correspond to each other.

[0045] It can be understood that the upper hanging beam 211 is parallel to the cross beam 122, and the lower hanging beam 212 is also parallel to the cross beam 122. The longitudinal hanging beam 213 is used to fix the relative position of the upper hanging beam 211 and the lower hanging beam 212. The wall hanging assembly 22 is used to fix the wall-mounted objects that need to be hung. The wall-mounted objects can be various devices or components in the inverter, PCS or energy storage system of the prior art.

[0046] It should be noted that the upper hanging beam 211 corresponds to one of the cross beams 122 on the side plate 13, which means that the setting position of the upper hanging beam 211 on the side plate 13 corresponds to the position of one of the cross beams 122 on the side plate 13, that is, the setting height of the upper hanging beam 211 relative to the base 11 corresponds to the setting height of one of the cross beams 122 relative to the base 11. When the weight of the wall-mounted object is transferred to the upper hanging beam 211, the load-bearing capacity of the upper hanging beam 211 can be directly transferred to the corresponding cross beam 122 at the position through the side plate 13, avoiding the weight from being transferred to the position on the side plate 13 that is not effectively supported by the cross beam 122, and the cross beam 122 will further transfer the gravity it bears to the column 121, and finally to the base 11. In this way, the wall-mounted object can be supported by the position with higher strength on the cabinet 1, avoiding deformation and damage of the cabinet 1 due to the weight of the wall-mounted object.

[0047] Similarly, the correspondence between the lower hanging beam 212 and the other cross beam 122 can refer to the implementation of the upper hanging beam 211 mentioned above, and will not be repeated here.

[0048] It should also be noted that compared with the separate setting method, the utility model directly hangs the wall-mounted object on the side panel 13 of the cabinet 1, thereby greatly shortening the distance between the wall-mounted object and the cabinet 1, which effectively shortens the length of the connecting cable and greatly reduces the cost.

[0049] Furthermore, the configuration of the wall-mounted component 22 includes at least the following implementation modes: in the first type of embodiment, the wall-mounted component 22 is only arranged on one of the upper hanging beam 211, the lower hanging beam 212 and the longitudinal hanging beam 213; in the second type of embodiment, at least two of the upper hanging beam 211, the lower hanging beam 212 and the longitudinal hanging beam 213 are provided with the wall-mounted component 22; in the third type of embodiment, the wall-mounted component 22 is arranged on all three of the upper hanging beam 211, the lower hanging beam 212 and the longitudinal hanging beam 213.

[0050] like Figures 3 to 6 As shown, in some embodiments of the energy storage system 10 , the side stand assembly 12 includes two parallel columns 121 , each column 121 is provided with a slot 1211 for accommodating a cross beam 122 , and each cross beam 122 is connected to the two columns 121 .

[0051] It can be understood that the groove wall profile of the slot 1211 is configured to match the outer contour of the beam 122 . After the beam 122 is placed in the slot 1211 , the groove wall of the slot 1211 will fit with the outer side wall of the beam 122 .

[0052] It should be noted that by providing support from two different positions with two columns 121 , the structural strength of the side stand assembly 12 can be improved, and bending deformation of a single column 121 due to uneven force can be avoided.

[0053] Furthermore, after the cross beam 122 is placed in the slot 1211, the configuration positions of the cross beam 122 and the column 121 can be further welded. Preferably, welding is performed along the slot wall contour of the slot 1211. In this way, the opening of the slot 1211 can greatly expand the welding connection position, improve the connection strength, and thus improve the durability and structural strength of the product.

[0054] like Figure 2 As shown, in some embodiments of the energy storage system 10, the cabinet 1 further includes a skeleton assembly 14. Figures 4 to 6 The skeleton assembly 14 includes a plurality of support columns 141 whose bottoms are welded to the base 11 , and the two upright columns 121 are welded and connected to the two support columns 141 in a one-to-one correspondence.

[0055] It can be understood that the skeleton assembly 14 plays a load-bearing role. The number of support columns 141 is configured to be at least two. The support columns 141 are configured to be perpendicular to the base 11. Each column 121 is welded to a corresponding support column 141, so that the load-bearing of each column 121 can be directly transferred to the support column 141, further improving the wall-hanging reliability of the product and preventing deformation damage.

[0056] like Figure 5As shown, in some embodiments of the energy storage system 10, each support column 141 includes a first bending edge 1411, a second bending edge 1412 and a third bending edge 1413 formed by bending, the second bending edge 1412 is located between the first bending edge 1411 and the third bending edge 1413, the second bending edge 1412 faces the column 121, and the first bending edge 1411 and the third bending edge 1413 are respectively welded to the column 121.

[0057] It can be understood that the first bending edge 1411, the second bending edge 1412 and the third bending edge 1413 are all formed by bending processing. It is preferred to configure the first bending edge 1411 and the second bending edge 1412 to intersect at 90°, and it is preferred to configure the second bending edge 1412 and the third bending edge 1413 to intersect at 90°. The right-angle matching relationship can improve the structural strength to a certain extent and avoid accidental bending between the two.

[0058] In some embodiments of the energy storage system 10 , each beam includes a first beam, a second beam, a third beam, and a fourth beam disposed one by one along the length direction of the column 121 ;

[0059] The first cross beam is connected to the top of the column 121 , the fourth cross beam is connected to the bottom of the column 121 , the second cross beam and the upper hanging beam 211 on the side plate 13 correspond to each other, and the third cross beam and the lower hanging beam 212 on the side plate 13 correspond to each other.

[0060] It can be understood that in this embodiment, the number of beams is configured to be four, and the four beams are arranged one by one at intervals, wherein the first beam and the fourth beam can fix the upper and lower ends of the column 121, and the second beam and the third beam are used to reinforce the position between the first beam and the fourth beam on the one hand, and on the other hand, they are also used to directly bear the gravity transmitted from the wall-mounted device 2, so as to further transfer the load-bearing to the column 121.

[0061] like Figure 3 and Figure 5 As shown, in some embodiments of the energy storage system 10, each beam includes a first beam 1221, a second beam 1222, a third beam 1223, a fourth beam 1224 and a fifth beam 1225 which are arranged one by one along the length direction of the column 121;

[0062] The first cross beam 1221 is connected to the top of the column 121, the fifth cross beam 1225 is connected to the bottom of the column 121, and the fourth cross beam 1224 divides the column 121 into a long section 1212 and a short section 1213 along the length direction. The second cross beam 1222 and the third cross beam 1223 are both located on the long section 1212, the second cross beam 1222 and the upper hanging beam 211 on the side plate 13 correspond to each other, and the third cross beam 1223 and the lower hanging beam 212 on the side plate 13 correspond to each other.

[0063] It can be understood that in this embodiment, the number of cross beams is configured to be five, and the five cross beams are arranged one by one along the length direction of the column 121. Among them, the first cross beam 1221 and the fifth cross beam 1225 are used to fix the two ends of the column 121. If the number of the columns 121 is set to multiple, the first cross beam 1221 and the fifth cross beam 1225 can fix the ends of each column 121.

[0064] It should be noted that when the wall-mounted height of the wall-mounted device 2 is higher relative to the base 11, the heights of the second beam 1222 and the third beam 1223 relative to the base 11 will also increase accordingly, thereby increasing the distance between the third beam 1223 and the fifth beam 1225. The setting of the fourth beam 1224 can reinforce the part of the column between the third beam 1223 and the fifth beam 1225, thereby ensuring the structural strength and improving the reliability of the wall-mounted.

[0065] like Figure 7 As shown, in some embodiments of the energy storage system 10, a direction perpendicular to the first side surface 131 is set as a first direction X;

[0066] The projection surface A of the upper hanging beam 211 in the first direction X at least partially overlaps with the projection surface B of one of the cross beams 122 in the first direction X; thus, the load-bearing of the upper hanging beam 211 can be directly transferred to the cross beam 122 corresponding to the projection surface B.

[0067] The projection surface C of the lower hanging beam 212 in the first direction X at least partially overlaps with the projection surface D of another beam 122 in the first direction X. Thus, the load-bearing capacity of the lower hanging beam 212 can be directly transferred to the beam 122 corresponding to the projection surface D.

[0068] It can be understood that the projection surface A and the projection surface B are configured to overlap at least partially, so that the wall-hanging height of the upper hanging beam 211 relative to the base 11 is the same or close to the wall-hanging height of the cross beam 122 relative to the base 11, and the wall-hanging weight is avoided as much as possible from being transferred through the side plate 13, effectively preventing load-bearing deformation. Similarly, the projection surface C and the projection surface D are configured to overlap at least partially, which can also ensure the structural strength of the product.

[0069] like Figure 3 As shown, in some embodiments of the energy storage system 10, the upper hanging beam 211, the lower hanging beam 212 and each longitudinal hanging beam 213 are sequentially connected to form a wall hanging frame 21;

[0070] Among them, the wall-mounted component 22 includes at least the following two embodiments: in the first embodiment, the wall-mounted component 22 includes a plurality of wall-mounted nuts 221, each of which is symmetrically arranged on the wall-mounted frame 21, and each of which is used to fix the wall-mounted objects; in the second embodiment, the wall-mounted component 22 includes a plurality of wall-mounted studs, each of which is symmetrically arranged on the wall-mounted frame 21, and each of which is used to fix the wall-mounted objects.

[0071] It can be understood that the wall-mounted nut 221 can be set on the wall-mounted frame 21 by welding. The wall-mounted object can be fixed on the wall by passing the bolt through the wall-mounted object and screwing it into the wall-mounted nut 221, that is, the relative position of the wall-mounted object and the wall-mounted frame 21 can be fixed.

[0072] The wall-mounted studs are used to pass through wall-mounted objects. When in use, the nuts are screwed onto the wall-mounted studs through which the wall-mounted objects have been passed, thereby completing the fixation of the wall-mounted objects, that is, completing the fixation of the relative positions of the wall-mounted frame 21 and the wall-mounted objects.

[0073] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments of the energy storage system 10, the energy storage system 10 further includes a hanging box 3, on which a plurality of fixing positions 31 are provided (the fixing positions 31 are shown in FIG. Figure 6 ), each fixing position 31 is connected to the wall-mounted component 22.

[0074] It can be understood that the hanging box 3 is used to accommodate various wall-mounted objects that need to be hung. For example, it can be used to accommodate PCS and / or inverters, and can also be used to accommodate other devices or components required by the energy storage system 10. The fixing position 31 is used to cooperate with the wall-mounted component 22 to complete the fixing of the hanging box 3.

[0075] like Figure 1 and Figure 2 As shown, in some embodiments of the energy storage system 10, the energy storage system 10 further includes a connecting device 4, please refer to Figures 4 to 6 The connecting device 4 includes a connecting tube 41 and a waterproof joint 42. The waterproof joint 42 is arranged on the side plate 13. The waterproof joint 42 is used for insertion. The connecting tube 41 is arranged on the second side surface 132. One end of the connecting tube 41 is connected to the hanging box 3, and the other end of the connecting tube 41 is connected to and covers the waterproof joint 42.

[0076] It can be understood that the connection device 4 is used to connect the mounting box 3 and the cabinet 1. The connection tube 41 is cylindrical, and further, the connection tube 41 can be configured to be formed by splicing a plurality of plate-like objects, or configured to be formed by bending and deforming a plate-like object. The number of waterproof joints 42 can be configured to be one or more, and each waterproof joint 42 can be used for cables or pipes to pass through.

[0077] Furthermore, a plurality of heat-insulating cottons may be arranged on the second side surface 132 , and each of the heat-insulating cottons is correspondingly arranged in a gap formed by the intersection of the upright column 121 and the cross beam 122 .

[0078] The implementation of this utility model has the following beneficial effects:

[0079] The utility model relates to an energy storage system. In the energy storage system, the load-bearing of two cross beams is transmitted to a base through the arrangement of upright columns, and then the position of an upper hanging beam on a side plate is arranged to correspond to the position of one of the cross beams on the side plate, and the position of a lower hanging beam on the side plate is arranged to correspond to the position of another cross beam on the side plate, so that the load-bearing of the upper hanging beam and the lower hanging beam can be transmitted to the two cross beams respectively;

[0080] In this way, after the mounted devices or components are fixed on the wall-mounted device as wall-mounted objects, the weight of the wall-mounted objects will be concentrated on the columns, beams and bases with greater strength, avoiding the side panels and other components from bearing deformation. At the same time, the wall-mounted devices or components can be connected to the inside of the cabinet using only short cables, which effectively reduces costs.
