DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0036] In the description of the present application, it should be understood that the terms "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined.

[0037] In the following embodiments, a first direction X, a second direction Y, and a third direction Z intersecting in pairs are introduced, wherein the first direction X is parallel to the height direction of the entire energy storage cabinet in the present embodiment, the second direction Y is parallel to the length direction of the bottom of the energy storage cabinet in the present embodiment, and the third direction Z is parallel to the width direction of the bottom of the energy storage cabinet in the present embodiment.

[0038] Reference Figures 1 to 4An energy storage cabinet includes a base 1 and a reinforcement mechanism 2. The base 1 has a first surface 10 and a second surface 11 arranged opposite to each other in a first direction X, and the first surface 10 is used to carry batteries. The reinforcement mechanism 2 includes a reinforcement component 20 arranged on the first surface 10 and a plurality of locking members 21 connected to the reinforcement component 20. The reinforcement component 20 is detachably connected to the base 1 through the locking member 21. The locking member 21 penetrates the first surface 10 and the second surface 11 in the first direction X, and the locking member 21 has a support end 210 protruding from the second surface 11.

[0039] By setting the reinforcing component 20 on the first surface 10 to strengthen the structural strength of the entire base 1, there is no need to thicken the base 1 additionally, thus avoiding excessive increase in the weight of the base 1 and increasing the occupancy rate of the external space. The detachable reinforcing component 20 can be flexibly replaced with different specifications and sizes as needed to improve the adaptability to different structural strength requirements. On the one hand, the locking member 21 serves as a fixing structure for fixing the reinforcing component 20, and on the other hand, the base 1 can be directly supported on the surface where the base 1 needs to be placed through the support end 210 protruding from the second surface 11, without the need to install an additional support structure on the second surface 11, thereby reducing the occupancy rate of the external space.

[0040] It should be noted that, refer to Figure 3 and Figure 4 In this embodiment, the locking member 21 can be a bolt. In order to improve the supporting stability of the locking member 21, the supporting end 210 of the locking member 21 is locked by screwing the nut 23, and the contact area between the supporting end 210 and the mounting surface can be further expanded through the cooperation of the nut 23, thereby further improving the supporting stability of the locking member 21.

[0041] In addition, it can be understood that in other embodiments, as needed, the bottom of the base 1 can also be equipped with structures such as support legs, pulleys (not shown in the figure) at the support end 210 to meet the needs of different application scenarios of the energy storage cabinet. In this case, the support legs and pulleys are fixed by using nuts 23.

[0042] In addition, it can be understood that in other embodiments, as needed, the locking components 21 can also be pre-buried in the position where the energy storage cabinet needs to be placed (not shown in the figure). During the placement of the energy storage cabinet, each locking component 21 passes through the second surface 11 and the first surface 10 in turn and is locked on one side of the first surface 10 by the nut 23 to achieve fixation, which will not be repeated here.

[0043] Specifically, in some embodiments, referring to Figures 1 to 4 The reinforcement assembly 20 includes a first reinforcement member 200 and a second reinforcement member 201 .

[0044] The first reinforcement member 200 is provided on the first surface 10 and extends in the second direction Y, the second reinforcement member 201 is provided on the first surface 10 and extends in the third direction Z, and the first reinforcement member 200 is connected to the second reinforcement member 201. In this embodiment, it is taken as an example that some locking members 21 are connected to the first reinforcement member 200, and some locking members 21 are connected to the second reinforcement member 201. In other embodiments, if the first reinforcement member 200 and the second reinforcement member 201 are fixedly connected in advance, the locking members 21 may be distributed only on the second reinforcement member 201 or only on the first reinforcement member 200, which will not be described in detail here.

[0045] The first reinforcement member 200 and the second reinforcement member 201 extend in different directions to improve the uniformity of coverage of the reinforcement structure. At the same time, the locking members 21 are distributed on the first reinforcement member 200 and the second reinforcement member 201 so that the supporting ends 210 of each locking member 21 are evenly distributed, thereby improving the stability of the support for the base 1 and improving the uniformity of force on each locking member 21.

[0046] Furthermore, it is understood that reference Figure 3 and Figure 4 In order to improve the connection strength between the locking member 21 and the first reinforcement member 200 and the second reinforcement member 201, a gasket 22 may be added between the locking member 21 and the first reinforcement member 200 and the second reinforcement member 201, thereby increasing the contact area and friction between the locking member 21 and the first reinforcement member 200 and the second reinforcement member 201, which is conducive to dispersing the force acting on the first reinforcement member 200 and the second reinforcement member 201 and reducing friction loss. In other embodiments, a sleeve structure (not shown in the figure) may be pre-installed in the first reinforcement member 200 and the second reinforcement member 201 for the locking member 21 to pass through and lock, so as to increase the contact area between the locking member 21 and the first reinforcement member 200 and the second reinforcement member 201.

[0047] In some embodiments, reference Figure 1 and Figure 2 The first reinforcement 200 has a first side 202 and a second side 203 that are arranged opposite to each other in the third direction Z. The first side 202 and the second side 203 are respectively provided with a second reinforcement 201. By further evenly arranging the first reinforcement 200 and the second reinforcement 201, it is beneficial to optimize the uniformity of the force of the overall structure of the first reinforcement 200 and the second reinforcement 201.

[0048] In addition, according to the extended arrangement structure of the first reinforcement member 200 and the second reinforcement member 201, in this embodiment, some locking members 21 are arranged on the first reinforcement member 200 in the second direction Y, and multiple locking members 21 are respectively arranged on each second reinforcement member 201 and arranged in the third direction Z. In other embodiments, the arrangement of the locking members 21 can also be flexibly adjusted as needed.

[0049] For example, refer to Figures 1 to 3 In order to further enhance the uniform force effect of the overall reinforcement component 20, at least one of the first side 202 and the second side 203 is provided with a plurality of second reinforcement members 201, and the plurality of second reinforcement members 201 are spaced apart in the second direction Y.

[0050] In addition, at least one second reinforcement member 201 located on the first side 202 and at least one second reinforcement member 201 located on the second side 203 are disposed opposite to each other in the third direction Z.

[0051] In this embodiment, Figure 2 As shown, a plurality of second reinforcement members 201 are disposed on both the first side 202 and the second side 203. Moreover, the second reinforcement members 201 located on the first side 202 correspond to the second reinforcement members 201 located on the second side 203 one by one and are opposite to each other in the third direction Z. At this time, the first reinforcement members 200 and the second reinforcement members 201 form an overall V-shaped arrangement structure on the first surface 10.

[0052] It is understandable that, in some embodiments, according to the size of the base 1 in the second direction Y, the spacing between adjacent second reinforcement members 201 in the second direction Y can be flexibly adjusted, which is beneficial to optimize the force uniformity of the overall reinforcement assembly 20.

[0053] In addition, in other embodiments, multiple second reinforcement members 201 may be provided only on the first side 202 or the second side 203 , which can be flexibly adjusted according to design requirements and equipment installation requirements on the first surface 10 , and will not be elaborated herein.

[0054] In addition, in some embodiments, the base 1 includes a substrate 12 and a frame 13 surrounding the substrate 12, the first surface 10 and the second surface 11 are located on the substrate 12, the frame 13 protrudes from the first surface 10 in the first direction X, and the reinforcing component 20 is connected to the frame 13. Specifically, the first reinforcing member 200 abuts against the frame 13 at both ends of the second direction Y, and the second reinforcing member 201 is connected to the first reinforcing member 200 at one end in the third direction Z, and the other end abuts against the frame 13.

[0055] In some embodiments, reference Figure 1 and Figure 3 The energy storage cabinet further includes a base frame 3, which is disposed on a side of the first surface 10 away from the second surface 11. The base frame 3 includes a plurality of first support members 30 extending in the first direction X, the plurality of first support members 30 are connected to the base 1, and the plurality of first support members 30 are spaced apart along the normal direction around the first surface 10.

[0056] In order to further enhance the structural strength of the base frame 3 , the base frame 3 includes a plurality of second support members 31 extending in the first direction X. The plurality of second support members 31 are connected to the first reinforcement member 200 and are arranged in the second direction Y at intervals.

[0057] Specifically, in this embodiment, four first support members 30 are provided, and the four first support members 30 are distributed one by one at the four corners of the frame 13. Two second support members 31 are provided, and the two second support members 31 are respectively close to the two ends of the first reinforcement member 200 in the second direction Y to avoid excessive occupation of the internal space of the energy storage cabinet.

[0058] In some embodiments, reference Figure 1 and Figure 3 The base frame 3 further includes a third reinforcing member 32 . In the direction surrounding the first surface 10 , the third reinforcing member 32 is connected between at least two adjacent first supporting members 30 .

[0059] Exemplarily, in this embodiment, a plurality of third reinforcing members 32 are provided and are spaced apart between two first supporting members 30 along the first direction X. The third reinforcing members 32 may be connected to adjacent first supporting members 30 using a Y-shaped or V-shaped rod structure to improve the supporting structural strength of the first supporting members 30. In other embodiments, only a straight rod may be used to connect the two first supporting members 30 horizontally or obliquely.

[0060] In addition, in some embodiments, reference Figure 1 and Figure 3 The base frame 3 further includes a fourth reinforcement member 33, and the fourth reinforcement member 33 is connected between at least part of the first support member 30 and the base 1. In this embodiment, the fourth reinforcement member 33 is exemplarily adopted as a right-angle rib plate structure connected between the frame 13 and the first support member 30, thereby further improving the structural strength of the first support member 30. In addition, it can be understood that in other embodiments, the number of the fourth reinforcement members 33 can be flexibly increased or decreased as needed, which will not be repeated here.

[0061] In addition, in some embodiments, reference Figure 1 and Figure 3 The base frame 3 also includes a top frame 34 , the top frame 34 and the frame 13 are arranged in the first direction X, and the first support member 30 is connected between the top frame 34 and the frame 13 .

[0062] It is understandable that the structure of the top frame 34 can be the same as that of the frame 13. The top frame 34, the frame 13 and the base frame 3 form the overall frame structure of the energy storage cabinet, thereby improving the overall structural stability. Figure 1 Based on the structure shown, the energy storage cabinet needs to further install sheet metal parts between adjacent first support members 30 and on the side of the top frame 34 away from the frame 13 to form a closed energy storage cabinet structure.

[0063] In addition, in some embodiments, reference Figure 1A connecting rod 35 is also connected to the top frame 34. The connecting rod 35 extends along the third direction Z and is opposite to the second support member 31 in the first direction X. The connecting rod 35 is connected to an end of the second support member 31 away from the base 1 to improve the stability of the base frame 3.

[0064] In addition, it should be noted that, referring to Figure 3 For example, the base plate 12 is provided with a plurality of fixing holes 120. The fixing holes 120 can facilitate the insertion of bolts and other components when placing battery packs and other equipment for energy storage in the energy storage cabinet, thereby quickly fixing the battery packs and other equipment. The positions of the fixing holes 120 are not unique and can be flexibly adjusted as needed, which will not be described in detail here.

[0065] Accordingly, an embodiment of the present application provides an energy storage device, which includes the above-mentioned energy storage cabinet, and the energy storage device may also include a battery pack disposed in the energy storage cabinet, etc. It is understandable that the energy storage device may have all the technical features and corresponding beneficial effects of the above-mentioned energy storage cabinet, which will not be repeated here.
