[0042] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described 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, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0043] As energy conservation, emission reduction and environmental protection have become the focus of people's attention, the application of energy storage technology has become more and more extensive. Among them, energy storage cabinets are a common energy storage equipment in the field of industrial and commercial energy storage. They usually have more batteries inside and are heavy overall. At present, most energy storage cabinets on the market are mainly installed by forklifts, which is not conducive to on-site installation in some outdoor installation scenarios; some are installed by hoisting, but the hoisting process is only to hoist the cabinets without batteries, and the batteries need to be installed separately on site, which makes the installation time-consuming and difficult.

[0044] In view of this, the utility model provides a frame assembly and an energy storage cabinet, in which a connecting protrusion is provided on one of the first connecting surface of the column and the second connecting surface of the first bottom frame, and a connecting recess is provided on the other, so that the first connecting surface and the second connecting surface have a larger connecting area, thereby improving the connection strength and increasing the bearing capacity of the support frame. The support frame can carry battery storage racks and batteries of greater weight. In this way, when the energy storage cabinet is installed by hoisting, the structural stability of the frame assembly during the hoisting process can be ensured, so that the battery can be placed in the battery storage rack for overall hoisting, thereby reducing the installation difficulty of the energy storage cabinet, shortening the installation time, and improving the installation efficiency.

[0045] Reference below Figure 1-Figure 11 The frame assembly 1 according to the first embodiment of the utility model is described.

[0046] The frame assembly 1 of this embodiment can be used in an energy storage cabinet 100. The frame assembly 1 can include: a battery storage rack 11 and a support rack 12.

[0047] Specifically, the battery storage rack 11 is constructed to accommodate the battery 3. For example, a plurality of battery accommodating portions may be provided on the battery storage rack 11. The plurality of battery accommodating portions are arranged in an array, and each battery accommodating portion may be provided with a battery 3 to ensure the power capacity of the energy storage cabinet 100.

[0048] The support frame 12 can be arranged outside the battery storage rack 11. The support frame 12 can be used to fix and support the battery storage rack 11, and can also serve as the main frame of the entire energy storage cabinet 100. The support frame 12 can define at least one functional area, such as Figure 1 As shown, the support frame 12 may be provided with two functional areas, one of which is used to set and install the battery storage rack 11, and the other may be used to set electronic control components, heat dissipation components or other components.

[0049] The support frame 12 may include a bottom frame 122, a column 121 and a top frame 123. The bottom frame 122 includes two first bottom frames 1221, which may be a solid structure or a hollow tube structure. The two first bottom frames 1221 are arranged opposite to each other and spaced apart along a first direction. For example, the first direction may be the length direction of the energy storage cabinet 100, that is, Figure 3 Alternatively, the first direction may also be the width direction of the energy storage cabinet 100, that is, Figure 3 Y direction shown in .

[0050] The battery storage rack 11 is fixedly connected to the first bottom frame 1221 , for example, by welding or bolting, so that the first bottom frame 1221 can play the role of supporting the battery storage rack 11 and the battery 3 .

[0051] The column 121 is vertical (i.e. Figure 3 The support frame 12 is provided with a plurality of columns 121, for example, there may be four columns 121, and the four columns 121 are respectively arranged at the four corners of the support frame 12. In this case, the bottom frame 122 and the top frame 123 may be in a square shape. Of course, more columns 121 may be arranged according to the number of functional areas inside the support frame 12, so as to ensure that each functional area has enough columns 121 to support it. At the same time, multiple functional areas may also be divided by the columns 121. Of course, when there are six columns 121, the bottom frame 122 and the top frame 123 are correspondingly formed in a square shape.

[0052] The bottom end of the column 121 is connected to the first bottom frame 1221, for example, by welding or bolting, and the top end of the column 121 is connected to the top frame 123, for example, by welding or bolting. The column 121 has a first connection surface 1211 on one side facing the first bottom frame 1221, and the first bottom frame 1221 has a second connection surface 1222. One of the first connection surface 1211 and the second connection surface 1222 is provided with a connection convex portion 1223, and the other is provided with a connection concave portion 1212. When the column 121 is connected to the first bottom frame 1221, the first connection surface 1211 and the second connection surface 1222 can fit each other, and the connection convex portion 1223 is embedded in the connection concave portion 1212. Optionally, the first connection surface 1211 and the second connection surface 1222 can be welded to better transfer the external force on the first bottom frame 1221 to the column 121.

[0053] Among them, embedding the connecting protrusion 1223 into the connecting recess 1212 can increase the connection area between the first connecting surface 1211 and the second connecting surface 1222. At the same time, it also makes the force on the first bottom frame 1221 better transmitted to the column 121, so that the lateral force can be converted into vertical force, which is beneficial to the dispersion of force and thus improves the bearing capacity of the support frame 12.

[0054] For example, part of the structure of the first connection surface 1211 is raised toward the second connection surface 1222 to form a connection convex portion 1223, and part of the structure of the second connection surface 1222 is recessed away from the first connection surface 1211 to form a connection concave portion 1212; or, part of the structure of the first connection surface 1211 is recessed away from the second connection surface 1222 to form a connection concave portion 1212, and part of the structure of the second connection surface 1222 is raised toward the first connection surface 1211 to form a connection convex portion 1223. There can be one or more connection convex portions 1223, and the number of connection concave portions 1212 corresponds to the connection convex portions 1223, so as to ensure that the first connection surface 1211 and the second connection surface 1222 can be well fitted for welding. In this way, the weld formed by the first connecting surface 1211 and the second connecting surface 1222 is longer and more complex in shape, forming a maze-like structure, which can significantly increase the welding strength of the first connecting surface 1211 and the second connecting surface 1222, thereby improving the connection strength between the column 121 and the first bottom frame 1221. The gravity borne by the first bottom frame 1221 can be better transmitted to the column 121, thereby increasing the bearing capacity of the support frame 12.

[0055] According to the frame assembly 1 of the embodiment of the utility model, the column 121 has a first connection surface 1211, the first bottom frame 1221 has a second connection surface 1222, one of the first connection surface 1211 and the second connection surface 1222 is provided with a connection protrusion 1223, and the other is provided with a connection recess 1212. In this way, the first connection surface 1211 and the second connection surface 1222 have a larger connection area, which significantly improves the connection strength between the column 121 and the first bottom frame 1221, so that the support frame 12 can carry a heavier battery storage rack 11 and battery 3. In this way, when installing the energy storage cabinet 100, the battery 3 can be placed in the battery storage rack 11 for integral hoisting, eliminating the need to install the battery separately after the cabinet body is hoisted, which is conducive to reducing the installation difficulty of the energy storage cabinet 100, shortening the installation time, improving the installation efficiency, and ensuring the structural stability of the frame assembly 1 during the hoisting process.

[0056] The following description will be made by taking the welding of the first connection surface 1211 and the second connection surface 1222 as an example.

[0057] Optionally, combined Figure 3 and Figure 4 The bottom frame may further include two second bottom frames 1226, and the two second bottom frames 1226 may be arranged along the second direction (ie Figure 3 The two bottom frames 1226 are arranged relative to each other and spaced apart from each other (in the Y direction shown in FIG), and both ends of each second bottom frame 1226 are connected to the two first bottom frames 1221, or both ends of each second bottom frame 1226 are connected to the pillars 121, or the second bottom frame 1226 is connected to both the first bottom frame 1221 and the pillars 121. In this way, the bottom frame formed by the two first bottom frames 1221 and the two second bottom frames 1226 is a quadrilateral, which has higher structural stability and can further improve the bearing capacity of the support frame 12.

[0058] In some embodiments, in combination Figure 5 and Figure 7 The first connection surface 1211 is the bottom end surface of the column 121, the first connection surface 1211 extends obliquely relative to the vertical direction, and a part of the structure of the first connection surface 1211 is recessed to form a connection recess 1212. The second connection surface 1222 is an end surface of the first bottom frame 1221 facing the column 121, the second connection surface 1222 is parallel to the first connection surface 1211, and a part of the structure of the second connection surface 1222 protrudes toward the first connection surface 1211 to form a connection protrusion 1223. In this way, the matching mode of the first connection surface 1211 and the second connection surface 1222 is relatively simple and easy to weld.

[0059] refer to Figure 7 and Figure 8When the column 121 and the first bottom frame 1221 are both hollow tube structures, the first connection surface 1211 refers to an annular surface formed by the bottom end surfaces of the four side walls of the column 121, and the second connection surface 1222 refers to an annular surface formed by the end surfaces of the four side walls of the first bottom frame 1221. Accordingly, the connection recess 1212 penetrates the side walls of the column 121 on both sides along the second direction, and the connection protrusion 1223 is formed on the end surfaces of the side walls of the second bottom frame 1226 on both sides along the second direction. In this way, the connection area of ​​the first connection surface 1211 and the second connection surface 1222 can be increased while reducing the weight of the support frame 12, thereby increasing the connection strength between the column 121 and the first bottom frame 1221, which is conducive to transferring the gravity borne by the first bottom frame 1221 to the column 121, thereby better dispersing the gravity of the battery 3.

[0060] In some embodiments, in combination Figure 5 and Figure 6 , the connecting recess 1212 is constructed to have an upward supporting force on the connecting protrusion 1223. Here, the upward supporting force can be the force of the connecting recess 1212 on the connecting protrusion 1223 upward in the vertical direction, or it can also be the force of the connecting recess 1212 on the connecting protrusion 1223 in other directions, but the force has a component force upward in the vertical direction. In this way, the gravity borne by the first bottom frame 1221 can be better transmitted to the column 121, thereby dispersing the force borne by the first frame, and ensuring the structural stability of the energy storage cabinet 100 during the hoisting process.

[0061] Optionally, combined Figure 5 and Figure 7 The connecting recess 1212 on the first connecting surface 1211 has a first side surface 12121 and a second side surface 12122 relative to each other. The second side surface 12122 is located at the lower side of the first side surface 12121. The second side surface 12122 can extend downward and toward the second connecting surface 1222 relative to the horizontal direction, or the second side surface 12122 can extend along the horizontal direction.

[0062] Correspondingly, the connecting protrusion 1223 on the second connecting surface 1222 has a first fitting surface and a second fitting surface, the second fitting surface is located at the lower side of the first fitting surface, and the second fitting surface is parallel to the second side surface 12122. In this way, the present embodiment can ensure that the second side surface 12122 always exerts an upward force or a force component on the first fitting surface, so as to ensure that the gravity borne by the first bottom frame 1221 can be better transmitted to the column 121.

[0063] In addition, the second side surface 12122 and the second fitting surface may also be arcuate surfaces or other shapes, and it is only necessary to ensure that the second side surface 12122 always exerts an upward force or a component force on the first fitting surface.

[0064] In some embodiments, in combination Figure 7 , Figure 8 and Fig.10 The column 121 and the bottom frame are both hollow tube structures. The support frame 12 may further include a positioning member 124. Specifically, the positioning member 124 includes a first positioning segment 1241 and a second positioning segment 1242, and the first positioning segment 1241 and the second positioning segment 1242 are perpendicular to each other, that is, the positioning member 124 is an L-shaped structure.

[0065] The first positioning section 1241 is embedded in the inner side of the column 121 to position the column 121 during the assembly process, and the second positioning section 1242 is embedded in the inner side of the first bottom frame 1221 to position the first bottom frame 1221 during the assembly process. Optionally, the first positioning section 1241 can be fixedly connected to the column 121, such as by welding or bolting, and the second positioning section 1242 can be fixedly connected to the first bottom frame 1221, such as by welding or bolting. During the assembly process, the column 121 can be sleeved on the first positioning section 1241, and the first bottom frame 1221 can be sleeved on the second positioning section 1242, and then the first connection surface 1211 and the second connection surface 1222 are fitted, and welding is performed along the contact line between the first connection surface 1211 and the second connection surface 1222.

[0066] In this way, on the one hand, the positioning piece 124 can be used to position the column 121 and the first bottom frame 1221, so that the first connecting surface 1211 and the second connecting surface 1222 are automatically aligned, thereby facilitating the welding of the first connecting surface 1211 and the second connecting surface 1222; on the other hand, connecting the column 121 with the first positioning section 1241 and connecting the first bottom frame 1221 with the second positioning section 1242 can further increase the connection strength between the column 121 and the first bottom frame 1221, ensure the reliability of the connection and the stability of the overall structure, and at the same time, it is also beneficial to better disperse the external force borne by the bottom frame 122, so as to improve the load-bearing performance of the support frame 12, thereby facilitating the later overall lifting of the energy storage cabinet 100.

[0067] In some embodiments, the first positioning section 1241 is welded to the column 121, and the second positioning section 1242 is welded to the first bottom frame 1221. For example, the side wall of the column 121 is provided with a plurality of first welding holes 1215, and the plurality of first welding holes 1215 are arranged at intervals, and the side wall of the first bottom frame 1221 is provided with a plurality of second welding holes 1225, and the plurality of second welding holes 1225 are arranged at intervals, and the column 121 and the first positioning section 1241 can be welded through the first welding holes 1215, and the column 121 and the second positioning section 1242 can be welded through the second welding holes 1225, so as to further increase the connection strength between the column 121 and the first bottom frame 1221.

[0068] In some embodiments, in combination Figure 5-Figure 10 , the first positioning section 1241 may be provided with a first connection hole 12411, the side wall of the column 121 may be provided with a first connection matching hole 1213, and the first positioning section 1241 and the column 121 are also connected by a connection pin that passes through the first connection matching hole 1213 and the first connection hole 12411 in sequence. In this way, during the assembly process before welding, after the first positioning section 1241 penetrates the column 121, the connection pin can be used to pass through the first connection matching hole 1213 and the first connection hole 12411 in sequence, so as to keep 124 relatively fixed with the column 121, and then the first bottom frame 1221 is sleeved on the second positioning section 1242 to facilitate welding.

[0069] In some alternative embodiments, the second positioning section 1242 may be provided with a second connection hole, the side wall of the first bottom frame 1221 may be provided with a second connection matching hole, and the second positioning section 1242 and the first bottom frame 1221 are also connected by a connection pin that passes through the second connection matching hole and the second connection hole in sequence. In this way, during the assembly process before welding, after the second positioning section 1242 penetrates the first bottom frame 1221, the connection pin can be used to pass through the second connection matching hole and the second connection hole in sequence, so as to keep 124 relatively fixed with the first bottom frame 1221, and then the column 121 is sleeved on the second positioning section 1242 to facilitate welding.

[0070] In some embodiments, reference Figure 3 The support frame 12 may further include a plurality of connecting beams 125, which may extend along the first direction, and the plurality of connecting beams 125 are arranged vertically at intervals, and each connecting beam 125 is connected to two columns 121 that are opposite and spaced along the first direction. In this way, by providing the connecting beams 125, the connection strength of the plurality of columns 121 can be further enhanced, thereby improving the overall structural stability of the support frame 12.

[0071] Optionally, the plurality of columns 121 may be divided into a plurality of column groups, each column group includes at least two columns 121 arranged opposite to each other and spaced apart in the first direction, and the plurality of connecting beams 125 are divided into a plurality of connecting groups, and the connecting beams 125 in each connecting group are used to connect at least two columns 121 in the corresponding column group. In this way, the overall structural stability and bearing performance of the support frame 12 can be improved, which is conducive to the overall hoisting and installation of the energy storage cabinet 100 in the later stage.

[0072] In some embodiments, in combination Figure 3 and Figure 4The bottom of the battery storage rack 11 has a lower support beam 111 extending along the first direction. There are multiple lower support beams 111, which are arranged in parallel and at intervals along the second direction. The lower support beam 111 is fixedly connected to the first bottom frame 1221, such as by snapping, welding, bolting, etc. The first direction and the second direction are perpendicular to each other. In this way, the lower support beam 111 can transfer the gravity of the battery storage rack 11 and the battery 3 to the first bottom frame 1221, and then transfer it to the column 121 by the first bottom frame 1221. At the same time, the lower support beam 111 can achieve a stable connection between the battery storage rack 11 and the support frame 12 to ensure the stability of the battery storage rack 11 during the hoisting process of the energy storage cabinet 100.

[0073] In some embodiments, in combination Figure 4 , Figure 8 and Fig. 9 The first bottom frame 1221 is provided with a plurality of accommodating notches 1224, which are arranged at intervals along the second direction, and the accommodating notches 1224 correspond to the lower support beam 111 one by one, and the accommodating notches 1224 penetrate part of the top wall and part of the side wall of the first bottom frame 1221. An assembly protrusion 1111 is provided at one end of the lower support beam 111 facing the first bottom frame 1221, and the assembly protrusion 1111 is inserted into the accommodating notch 1224. An avoidance notch 1112 is formed on the side of the assembly protrusion 1111, so that a part of the first bottom frame 1221 is engaged with the avoidance notch 1112. In this way, through the cooperation of the accommodating notches 1224 and the assembly protrusion 1111, the position of the lower support beam 111 on the first bottom frame 1221 can be ensured to be fixed, so as to facilitate the welding of the lower support beam 111 and the first bottom frame 1221.

[0074] In some embodiments, the lower support beam 111 and the first bottom frame 1221 are welded. For example, welding can be performed along the contact gap between the first bottom frame 1221 and the lower support beam 111, using a notch welding process to increase the weld length and increase the lap strength.

[0075] In some embodiments, in combination Figure 1-Figure 3 The battery storage rack 11 may further include: a stand 112, an upper support beam and a battery bracket 113. The stand 112 extends vertically. There are multiple stands 112 arranged relatively along the second direction. The bottom end of the stand 112 is fixedly connected to the lower support beam 111. The top end of the stand 112 is connected to the upper support beam. There are multiple battery brackets 113. Multiple battery brackets 113 are arranged vertically at intervals. The battery 3 can be arranged on the battery bracket 113. In this way, the battery storage rack 11 has a relatively simple structure and is easy to manufacture and implement.

[0076] In some embodiments, in combination Figure 1-Figure 3 as well as Fig.11The frame assembly 1 may further include: a lifting block 126. Specifically, the lifting block 126 is fixedly arranged at the top of the column 121, and the lifting block 126 can be used to install the lifting ring 21. The lifting block 126 can be embedded in the inner cavity of the column 121 to ensure the installation stability of the lifting block 126 on the column 121. During the lifting process, the force borne by the column 121 can be transmitted to the lifting ring 21 through the lifting block 126, and then transmitted to the lifting equipment.

[0077] In some embodiments, the frame assembly 1 may further include: the side wall of the column 121 may be provided with a plurality of third welding holes 1216. When welding the lifting block 126 and the column 121, the column 121 and the lifting block 126 may be welded through the third welding holes 1216. The welding method may be plug welding. In this way, the installation reliability of the lifting block 126 can be ensured, thereby ensuring the stability and safety of the energy storage cabinet 100 with a large weight during overall lifting. In addition, the welding method is relatively simple and easy to implement.

[0078] In some embodiments, in combination Figure 7 and Fig.11 A first positioning hole 1261 may be provided on the lifting block 126, and a second positioning hole 1214 may be provided on the side wall of the column 121. The column 121 and the lifting block 126 are positioned by positioning pins that pass through the second positioning hole 1214 and the first positioning hole 1261 in turn. In this way, before welding, the lifting block 126 and the column 121 may be positioned using the positioning pins, which is beneficial for transmitting the force on the column 121 to the lifting block 126. In addition, it can also ensure the position stability of the lifting block 126 relative to the column 121 during the welding process, reduce the difficulty of welding, and help improve the welding efficiency.

[0082] For example, the housing assembly 2 may include a top plate 23, a bottom plate and a plurality of side plates 22, which together cover the frame assembly 1. For example, the top plate 23, the bottom plate and the plurality of side plates 22 are all fixed to the support frame 12, and together define an openable and closable cavity, and a partial structure of one of the side plates 22 along the first direction may serve as a door body 24 to open or close the cavity. The housing assembly 2 may better protect the battery 3. Of course, the housing assembly 2 may also be provided with a ventilation window or other electrical components, and the lifting ring 21 is at the top of the housing assembly 2 and is fixedly connected to the lifting block 126.

[0083] According to the energy storage cabinet 100 of the embodiment of the utility model, by setting the frame assembly 1 in the above embodiment, the connection area and connection strength between the column 121 and the first bottom frame 1221 are significantly increased, and the support frame 12 can carry a battery storage rack 11 and a battery 3 of greater weight, so that the energy storage cabinet 100 as a whole can be installed by hoisting, and the structural stability of the frame assembly 1 during the hoisting process can be ensured, thereby reducing the installation difficulty of the energy storage cabinet 100, shortening the installation time, and improving the installation efficiency.
