Description

Technical Field

[0001] This invention belongs to the field of cabinet technology, and more specifically, relates to a cabinet frame. Background Technology

[0002] Server racks are typically used to store computers, related control equipment, and electrical equipment. Server racks can protect the stored equipment, shield electromagnetic interference, arrange the equipment in an orderly and neat manner, and facilitate subsequent maintenance.

[0003] For cabinets equipped with power modules and energy storage devices (i.e., uninterruptible power supplies), in order to facilitate grid connection and reduce the overall space occupied by the cabinet, the existing technology matches a power distribution module inside the cabinet. Specifically, the inner cavity of the cabinet is divided into a first cavity and a second cavity distributed on the left and right. The power module and energy storage device are set in the first cavity, and the power distribution module is set in the second cavity. In order to facilitate maintenance operations of each module, the cabinet door is divided into two groups: a first door that covers the power module and energy storage device, and a second door that covers the power distribution module.

[0004] The inventors discovered that because the weight of the power module and energy storage device is much greater than that of the power distribution module, the second cavity accounts for a large proportion of the total weight of the unit. This results in uneven stress on the cabinet frame, causing the frame to deform. In particular, deformation of the front part of the frame leads to a height difference between the first and second door panels after installation, reducing the overall aesthetics of the cabinet and affecting the opening and closing of the door panels.

[0059] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0060] It should be noted that the orientation or positional relationship indicated by "front", "rear", "inner", "outer", "upper", and "lower" in this embodiment is based on the orientation of the cabinet after installation. The front of the cabinet represents "front", the back represents "rear", the top represents "upper", the bottom represents "lower", "inner" refers to the side facing the inside of the cabinet in the left-right direction, and "outer" refers to the side facing the outside of the cabinet in the left-right direction.

[0061] In addition, the front-back direction defined in the embodiments of the present invention refers to the spacing direction between the front and back of the cabinet, the left-right direction refers to the spacing direction between the two sides of the cabinet, and the up-down direction refers to the spacing direction between the top and bottom surfaces of the cabinet.

[0062] Please refer to the following: Figures 1 to 3The rack frame provided by the present invention will now be described. The rack frame includes a frame body 1 and partitioned vertical frames 2 disposed inside the frame body 1. The frame body 1 includes a front rectangular frame 11 and longitudinal beams; the front end of the longitudinal beams is connected to the corner points of the front rectangular frame 11; a first corner connector 3 is provided between the longitudinal beams and the front rectangular frame 11; the first corner connector 3 has a first support plate 31; a second corner connector 4 is also provided at the corner points of the front rectangular frame 11; the second corner connector 4 has a second support plate 41. The first support plate 31 and the second support plate 41 are respectively supported between the horizontal beam and the front vertical beam 112 of the front rectangular frame 11.

[0063] The vertical frame 2 divides the main frame 1 into a left frame and a right frame. The left and right frames have different volumes. Figure 1 and Figure 2 For example, the volume of the left frame is smaller than that of the right frame. Therefore, the left frame is used to house the power distribution module, and the right frame is used to house the power module and energy storage device. To facilitate zoned maintenance of each module, the left frame has a left door panel at the front, and the right frame has a right door panel at the front. Specifically, the left and right door panels are respectively installed on the front rectangular frame 11.

[0064] Specifically, because the weight of the power module and energy storage device is much greater than that of the power distribution module, the right frame accounts for a larger proportion of the overall weight of the unit. This causes the cabinet frame to tend to tilt to the right, and there is a tendency for the angle to change at each corner of the main frame 1. If the front rectangular frame 11 deforms, there will be a height difference between the left and right door panels after installation.

[0065] To prevent deformation of the front rectangular frame 11 and maintain its rectangular shape, second corner connectors 4 are installed at the corners of the front rectangular frame 11, and first corner connectors 3 are installed between the longitudinal beam and the front rectangular frame 11. It should be noted that the corners of the front rectangular frame 11 are at least one of the lower left, lower right, upper left, and upper right corners. In other words, at least one corner of the front rectangular frame 11 has a first corner connector 3 installed, and at least one corner has a second corner connector 4 installed. The corners where the first corner connector 3 and the second corner connector 4 are installed can be the same corner or different corners.

[0066] The first corner connector 3 has a first support plate 31 and the second corner connector 4 has a second support plate 41. The first support plate 31 and the second support plate 41 are respectively supported between the horizontal beam and the vertical beam 112 of the front rectangular frame 11, which can keep the vertical beam 112 of the front rectangular frame 11 perpendicular to the horizontal beam at all times, and avoid the problem that the angle at the corner of the front rectangular frame 11 changes due to uneven force, and the vertical beam 112 tilts or deflects.

[0067] It should be noted that the aforementioned longitudinal beams include upper longitudinal beam 13 and lower longitudinal beam 12, with two upper longitudinal beams 13 and two lower longitudinal beams 12. In addition, the main frame 1 also includes a rear rectangular frame 14. The rear rectangular frame 14, the front rectangular frame 11, the two upper longitudinal beams 13 and the two lower longitudinal beams 12 are spliced ​​together to form a hexahedral frame structure.

[0068] The front rectangular frame 11 has two front vertical beams 112 and two horizontal beams. The four beams are connected in sequence to form a rectangular frame structure.

[0069] Compared with the prior art, the cabinet frame provided by the present invention has a first corner connector 3 between the longitudinal beam and the front rectangular frame 11, and a second corner connector 4 at the corner of the front rectangular frame 11. Both the first corner connector 3 and the second corner connector 4 are used to increase the connection strength at the corner of the front rectangular frame 11 and increase the deformation resistance of the front rectangular frame 11. Moreover, the first support plate 31 and the second support plate 41 are used to support the corner of the front rectangular frame 11, ensuring that the corner of the front rectangular frame 11 is always in a vertical state and that the corner of the front rectangular frame 11 does not change angle, thereby avoiding deformation of the front rectangular frame 11 and ensuring that there is no height difference after the two sets of doors are installed.

[0070] In some embodiments, the first corner connector 3 and the second corner connector 4 described above can also adopt the structure shown in Figure 3. See [reference needed]. Figure 3 The longitudinal beam includes a lower longitudinal beam 12, the front end of which is connected to the lower corner of the front rectangular frame 11; the lower end of the front vertical beam 112 of the front rectangular frame 11 extends downward from the front lower horizontal beam 111 of the front rectangular frame 11, forming a lower extension 1121.

[0071] The first corner connector 3 is connected to the inner front side of the lower longitudinal beam 12, the rear side of the lower extension 1121, and the rear side of the front lower crossbeam 111; the surface of the first support plate 31 is perpendicular to the front-rear direction, and the first support plate 31 has a first anti-deformation inclined edge 311 that slopes downward from the inside to the outside.

[0072] The second corner connector 4 is connected to the inner side of the front vertical beam 112 and the top surface of the front lower cross beam 111; the surface of the second support plate 41 is perpendicular to the front-rear direction, and the second support plate 41 has a second anti-deformation inclined edge 411 that is inclined upward from the inside to the outside.

[0073] The front rectangular frame 11 has two front vertical beams 112, a front lower horizontal beam 111, and a front upper horizontal beam 113. The four beams are connected in sequence to form a rectangular frame structure.

[0074] The lower extension 1121 of the front vertical beam 112 rests on the ground, serving to support the main frame 1. The lower extension 1121 can raise the front lower crossbeam 111, thus raising the entire main frame 1. It should be noted that the main frame 1 has a lower extension 1121 at each of the four corners at its bottom.

[0075] Since the second corner connector 4 is located on the top surface of the front lower crossbeam 111, and the first corner connector 3 is located on the rear side of the front lower crossbeam 111 and the rear side of the lower extension 1121, if the first corner connector 3 and the second corner connector 4 are installed at the same corner point of the front rectangular frame 11, it can be considered that the second corner connector 4 is located above the lower corner point, the first corner connector 3 is located below the lower corner point, and the second corner connector 4 is located in front of and above the first corner connector 3.

[0076] The first support plate 31 has a first anti-deformation inclined side 311, and the second support plate 41 has a second anti-deformation inclined side 411. When the rectangular frame 11 has a tendency to deflect to the right, the first support plate 31 and the second support plate 41 can transmit the supporting force to the first anti-deformation inclined side 311 and the second anti-deformation inclined side 411 while supporting the front vertical beam 112 of the front rectangular frame 11, so that the supporting force is dispersed, thereby increasing the strength of the first corner connector 3 and the second corner connector 4 and avoiding damage to the first corner connector 3 and the second corner connector 4 due to stress concentration.

[0077] Furthermore, when the current vertical beam 112 tends to deflect, the deflection center of the front vertical beam 112 is the connection point with the front lower horizontal beam 111. If the deflection force is very large, it may damage the first corner connector 3 and the second corner connector 4, causing deformation of the first corner connector 3 and the second corner connector 4. To avoid the above problem, in this embodiment, since the second corner connector 4 is located above the lower corner point and the first corner connector 3 is located below the lower corner point, and the first anti-deformation inclined edge 311 slopes downward from the outside to the inside, and the second anti-deformation inclined edge 411 slopes upward from the outside to the inside, the inclination directions of the two anti-deformation inclined edges are opposite. Conversely, in the left-right direction, regardless of which direction the front vertical beam 112 tends to deflect, one of the main body of the front vertical beam 112 (the part located above the front upper crossbeam 113) and the lower extension 1121 compresses one of the corner connectors, while the other stretches the other corner connector. The stretched corner connector disperses the tensile force through its anti-deformation inclined side, avoiding damage from compression. Therefore, by making the inclination directions of the two anti-deformation inclined sides opposite, when the deflection force on the front vertical beam 112 is very large, it can ensure that at least one of the first corner connector 3 and the second corner connector 4 plays a stable supporting role.

[0078] In some embodiments, the first corner connector 3 described above can be adopted as follows: Figure 6 The structure shown is described in the following document. Figure 6The first corner connector 3 is an integral structure, including the first support plate 31, the first connecting plate 32, the first bending plate 33 and the first top plate 34 mentioned above. The first support plate 31 is attached to the rear side of the lower extension 1121 and the rear side of the front lower crossbeam 111, and is connected to the lower extension 1121 and the front lower crossbeam 111 in the front-back direction; one section of the inner side edge of the first support plate 31 is the first anti-deformation inclined edge 311; the first connecting plate 32 is located below the lower longitudinal beam 12, the plate surface is perpendicular to the left-right direction, and the front edge is connected to the outer edge of the first support plate 31; the outer edge of the first bent plate 33 is connected to the upper edge of the first connecting plate 32; the first bent plate 33 is attached to the inner side and the lower bottom surface of the lower longitudinal beam 12, and is connected to the lower longitudinal beam 12 in the left-right direction and the up-down direction; the outer edge of the first upper top plate 34 is connected to the upper edge of the first bent plate 33, and the front edge is folded down to form the first flange 35, the first flange 35 abuts against the first support plate 31, and the first flange 35 is connected to the front rectangular frame 11 in the front-back direction.

[0079] The first corner connector 3 is formed by bending a plate. The integrated structure can increase the strength of the first corner connector 3 itself and enhance its support for the lower longitudinal beam 12, the front vertical beam 112, and the front lower horizontal beam 111.

[0080] Since the first corner connector 3 is fixed to the lower protrusion 1121, meaning that the first corner connector 3 does not occupy the inner cavity enclosed by the frame body 1, it is preferable to install the first corner connector 3 at both the lower left and lower right corners of the front rectangular frame 11. Installing the first corner connector 3 at both lower corners further ensures the structural stability of the front rectangular frame 11 and prevents changes in the angles at its various corners.

[0081] The first connecting plate 32 serves as a transitional connection between the outer side of the first support plate 31 and the lower side of the first bending plate 33. The first upper top plate 34 and the first flange 35 serve as a transitional connection between the upper side of the first bending plate 33 and the upper side of the first support plate 31, thereby ensuring that the first corner connector 3 forms a three-dimensional structure that can be fixed along the vertical, horizontal and front-back directions.

[0082] In addition, the rear edge of the first connecting plate 32 is the first side inclined edge 321, which slopes upward from front to back. The first side inclined edge 321 can disperse the deflection force along the vertical direction; the rear edge of the first upper top plate 34 is the first upper inclined edge 341, which slopes backward from the inside to the outside. The first upper inclined edge 341 can disperse the deflection force along the horizontal direction.

[0083] In some embodiments, the second corner connector 4 described above can be adopted as follows: Figure 3 and Figure 7 The structure shown is described in the following document. Figure 3 and Figure 7 The second corner connector 4 is an integral structure, including the aforementioned second support plate 41, second side plate 43, and second bottom plate 42. The second side plate 43 is attached to the inner side of the front vertical beam 112 and connected to the front vertical beam 112 in the left-right direction; the rear end edge of the second side plate 43 is connected to the outer edge of the second support plate 41; the second bottom plate 42 is attached to the top surface of the front lower crossbeam 111 and connected to the front lower crossbeam 111 in the up-down direction; the rear end edge of the second bottom plate 42 is connected to the lower edge of the second support plate 41, and the outer edge of the second bottom plate 42 is folded upward to form a second flange 421, which abuts against the second side plate 43 and is connected to the front vertical beam 112 in the left-right direction.

[0084] The second corner connector 4 is also formed by bending a single plate. The integrated structure can increase the strength of the second corner connector 4 itself and enhance its strength in supporting the front vertical beam 112 and the front lower horizontal beam 111.

[0085] The second support plate 41, the second side plate 43, and the second bottom plate 42 are arranged vertically in pairs. The second support plate 41 not only supports the front vertical beam 112 and the front lower horizontal beam 111, but also serves as a transitional connection between the second side plate 43 and the second bottom plate 42, realizing the integral bending and forming of the second corner connector 4.

[0086] It should be noted that the second corner connector 4 can be installed at both the lower left and lower right corners of the front rectangular frame 11, or, depending on the position of other components at the lower corners to avoid interference, the second corner connector 4 can be installed only at the lower left or lower right corners.

[0087] In some embodiments, the lower corner of the aforementioned front rectangular frame 11 may also be used as follows: Figure 7 The structure shown is described in the following document. Figure 7 The lower corner of the front rectangular frame 11 is also provided with a first reinforcing plate 44, which is connected to the second corner connector 4 along the vertical and horizontal directions respectively.

[0088] Specifically, in the main frame 1, the crossbeams, front vertical beams 112 and longitudinal beams are all C-shaped steel. The C-shaped grooves of the longitudinal beams and front vertical beams 112 face inward, the C-shaped grooves of the lower crossbeam face downward, and the C-shaped grooves of the upper crossbeam face backward.

[0089] Multiple assembly holes are provided on the crossbeams, front vertical beams 112, and longitudinal beams, and these assembly holes are spaced apart along the length of each beam. Providing multiple assembly holes facilitates the assembly of other components onto each beam and also reduces the overall weight of the frame body 1.

[0090] like Figure 3 , Figure 6 and Figure 9 In the middle, the first corner connector 3 and the second corner connector 4 are fixed to the assembly holes of each beam by multiple fasteners.

[0091] The first reinforcing plate 44 is an L-shaped plate structure, with its vertical part located inside the front vertical beam 112 and its horizontal part located inside the front lower cross beam 111. The first reinforcing plate 44 is connected to the second corner connector 4 to further increase the support strength at the lower corner of the front rectangular frame 11.

[0092] In addition, the first reinforcing plate 44 is provided with multiple first fixing holes on its vertical and horizontal parts, and the second bottom plate 42 and the second side plate 43 are provided with multiple second fixing holes. The multiple second fixing holes and the multiple first fixing holes are axially corresponding one by one, and are also axially corresponding one by one with certain assembly holes on the front lower crossbeam 111 and the front vertical beam 112, so as to fasten the second corner connector 4, the front rectangular frame 11 and the first reinforcing plate 44 with fasteners.

[0093] In some embodiments, the front vertical beam 112 and the front lower horizontal beam 111 may also be connected by a method such as Figure 1 , Figure 3 , Figure 6 and Figure 9 The structure shown is described in the following document. Figure 1 , Figure 3 , Figure 6 and Figure 9 The lower end of the front vertical beam 112 of the front rectangular frame 11 extends downward to the front lower crossbeam 111 of the front rectangular frame 11, forming a lower extension 1121; the first corner connector 3 is connected to the lower extension 1121 and the front lower crossbeam 111 in the front-rear direction respectively; a second reinforcing plate 114 is connected between the inner cavity of the lower extension 1121 and the inner cavity of the front lower crossbeam 111, and a first support body 115 is also provided on the inner side of the lower extension 1121 and below the front lower crossbeam 111, and the second reinforcing plate 114 is also connected to the first support body 115.

[0094] A first support body 115 is added to the inner side of the lower extension 1121. The first support body 115 and the lower extension 1121 are supported on the ground together to increase the support area and the support strength of the frame body 1, thereby improving the stability of the frame body 1.

[0095] Specifically, the first support 115 is a shell-like structure, such as... Figure 9 As shown, it has a top plate, side plates and bottom plate, which form a C-shaped plate structure with the C-shaped slot facing forward. The top plate is connected to the bottom surface of the front lower crossbeam 111. In addition, a long strip-shaped support shell is provided inside the cavity of the C-shaped plate, and the support shell is connected to the lower protrusion 1121.

[0096] It should be noted that the length of the C-shaped plate in the left-right direction is greater than the length of the lower protrusion 1121 and the support shell in the left-right direction, which can increase the support area of ​​the first support body 115.

[0097] In addition, a second reinforcing plate 114 is provided inside the front rectangular frame 11. The second reinforcing plate 114 is a 7-shaped plate structure or a Z-shaped plate structure. Its vertical part is located inside the lower extension 1121, and its upper horizontal part is located inside the front lower crossbeam 111. The second reinforcing plate 114 is connected to the first support body 115 to further increase the connection strength between the first support body 115 and the lower corner of the front rectangular frame 11.

[0098] Similar to the first reinforcing plate 44, the second reinforcing plate 114 has multiple first fixing holes on its vertical and horizontal parts. The first support body 115 has multiple second fixing holes on its horizontal part (i.e., the top plate of the C-shaped plate) and vertical part (i.e., the support shell). The multiple second fixing holes and the multiple first fixing holes are axially corresponding one by one, and are also axially corresponding to certain assembly holes on the front lower crossbeam 111 and the lower extension 1121, so as to fasten the second reinforcing plate 114, the front rectangular frame 11 and the first support body 115 with fasteners.

[0099] In some embodiments, the second corner connector 4 is disposed at the lower left corner and / or lower right corner of the front rectangular frame 11; the lower end of the partitioned vertical frame 2 abuts against the front lower crossbeam 111, and the connection between the lower end of the partitioned vertical frame 2 and the front lower crossbeam 111 is also provided with a second corner connector 4; a second support body 21 is also connected below the front lower crossbeam 111, such as... Figure 1 As shown, the second support 21 corresponds vertically to the partition vertical frame 2.

[0100] It should be noted that the second corner connector 4 can be installed at both the lower left and lower right corners of the front rectangular frame 11, or, depending on the position of other components at the lower corner of the front rectangular frame 11, the second corner connector 4 can be installed only at the lower left or lower right corner to avoid interference.

[0101] In addition, in order to further enhance the connection strength between the partition vertical frame 2 and the front rectangular frame 11 and to prevent deformation at the connection between the partition vertical frame 2 and the front rectangular frame 11, a second corner connector 4 can be added at the lower connection of the two to support the partition vertical frame 2 and the front lower crossbeam 111.

[0102] It should be noted that, since the bottom four corners of the frame body 1 are supported by the lower extension 1121 and the first support 115, the front lower crossbeam 111 is raised. In order to decompose the downward pressure of the partition vertical frame 2 and the second corner connector 4 on the front lower crossbeam 111, a second support 21 is also provided below the front lower crossbeam 111 directly opposite the partition vertical frame 2 to support the partition vertical frame 2 and prevent the front lower crossbeam 111 from being deformed by downward pressure.

[0103] Specifically, the second support 21 can adopt the same structure as the first support 115.

[0104] In some embodiments, the frame body 1 described above may also adopt the following: Figure 1 , Figure 2 , Figure 4 and Figure 5 The structure shown is described in the following document. Figure 1 , Figure 2 , Figure 4 and Figure 5 The longitudinal beams include a lower longitudinal beam 12 and an upper longitudinal beam 13; the front end of the lower longitudinal beam 12 is connected to the lower corner of the front rectangular frame 11; the front end of the upper longitudinal beam 13 is connected to the upper corner of the front rectangular frame 11. The first corner connector 3 and the second corner connector 4 are both located at the lower corner of the front rectangular frame 11.

[0105] A third corner connector 5 is provided between the upper longitudinal beam 13 and the front rectangular frame 11, and between the upper end of the partition vertical frame 2 and the front rectangular frame 11; the third corner connector 5 has a third support plate 51 extending in the left and right direction; a fourth corner connector 6 is provided at the upper corner of the front rectangular frame 11 and at the connection between the upper end of the partition vertical frame 2 and the front rectangular frame 11; the fourth corner connector 6 has a fourth support plate 61 extending in the left and right direction.

[0106] The first corner connector 3 and the second corner connector 4 are both located at the lower corner of the front rectangular frame 11, and the third corner connector 5 and the fourth corner connector 6 are both located at the upper corner of the front rectangular frame 11. In other words, the upper and lower corners of the front rectangular frame 11 are reinforced and fixed by corner connectors, which can further increase the overall strength of the front rectangular frame 11 and prevent deformation.

[0107] In addition, the third corner connector 5 has a third support plate 51, which is supported between the front vertical beam 112 and the front upper cross beam 113. The fourth corner connector 6 has a fourth support plate 61, which is supported between the front vertical beam 112 of the front rectangular frame 11, the front vertical beam 112 of the partitioned vertical frame 2, and the front upper cross beam 113 of the front rectangular frame 11. This ensures that the front vertical beam 112 and the front upper cross beam 113 of the front rectangular frame 11 and the front vertical beam 112 and the front upper cross beam 113 of the partitioned vertical frame 2 remain perpendicular to each other, thus avoiding the problem of the front vertical beam 112 tilting or deflecting due to uneven force, which causes the angle at the corner of the front rectangular frame 11 to change.

[0108] Specifically, the third support plate 51 has a third anti-deformation inclined edge 511, which slopes downward from the inside to the outside, and the fourth support plate 61 has a fourth anti-deformation inclined edge, which also slopes downward from the inside to the outside.

[0109] When the rectangular frame 11 has a tendency to deflect to the right, the third support plate 51 and the fourth support plate 61 can transmit the supporting force to the third anti-deformation inclined side 511 and the fourth anti-deformation inclined side while supporting the front vertical beam 112, so that the supporting force is dispersed, thereby increasing the strength of the third corner connector 5 and the fourth corner connector 6 and avoiding damage to the third corner connector 5 and the fourth corner connector 6 due to stress concentration.

[0110] In some embodiments, the third corner connector 5 described above can be adopted as follows: Figure 4 and Figure 8 The structure shown is described in the following document. Figure 4 and Figure 8 The third corner connector 5 is an integral structure, including the aforementioned third support plate 51, third outer side plate 52, and third top plate 53.

[0111] The third support plate 51 is attached to the rear side of the front upper crossbeam 113 and is connected to the front upper crossbeam 113 in the front-rear direction; the front edge of the third outer plate 52 is connected to the outer edge of the third support plate 51; the third outer plate 52 is attached to the inner side of the upper longitudinal beam 13 and the inner side of the front vertical beam 112, and is connected to the front vertical beam 112 and the upper longitudinal beam 13 in the left-right direction. The surface of the third top plate 53 is perpendicular to the vertical direction, the outer edge of the third top plate 53 is connected to the upper edge of the third outer plate 52, and the front edge is connected to the upper edge of the third support plate 51.

[0112] It should be noted that the third support plate 51 may include two parts, such as Figure 8 As shown, part of it connects to the front upper crossbeam 113 in the front-rear and vertical directions, and part of it is supported below the front upper crossbeam 113, forming a third anti-deformation inclined side 511; the third support plate 51 can also be a flat plate, such as Figure 4 As shown.

[0113] The third corner connector 5 is also formed by bending a single plate. The integrated structure can increase the strength of the third corner connector 5 itself and enhance its strength in supporting the front vertical beam 112 and the front upper horizontal beam 113.

[0114] The structure of the fourth corner connector 6 is similar to that of the second corner connector 4, except that it is symmetrically arranged relative to the left and right directions.

[0115] In some embodiments, the frame body 1 described above may also adopt the following: Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The main frame 1 also includes a rear rectangular frame 14; the rear end of the lower longitudinal beam 12 is connected to the lower corner of the rear rectangular frame 14; the rear end of the upper longitudinal beam 13 is connected to the upper corner of the rear rectangular frame 14; a first corner connector 3 is also provided between the lower longitudinal beam 12 and the rear rectangular frame 14; a second corner connector 4 is also provided at the lower corner of the rear rectangular frame 14; a second corner connector 4 is also provided at the connection between the lower end of the partitioned vertical frame 2 and the rear rectangular frame 14; a third corner connector 5 is also provided between the upper longitudinal beam 13 and the rear rectangular frame 14.

[0116] The structure of the rear rectangular frame 14 is exactly the same as that of the front rectangular frame 11, including two rear vertical beams, a rear upper horizontal beam, and a rear lower horizontal beam. A first corner connector 3 and a second corner connector 4 are installed at the lower corner of the rear rectangular frame 14, and a third corner connector 5 is installed at the upper corner of the rear rectangular frame 14. These measures increase the connection strength at each corner of the rear rectangular frame 14, thereby increasing the overall deformation resistance of the frame body 1.

[0117] Since the rear rectangular frame 14 does not require routine maintenance and the assembled back panel is in a fixed state and is not open, multiple crossbeams and multiple diagonal beams can be installed on the rear rectangular frame 14 to further increase its resistance to deformation.

[0118] In some embodiments, the upper front crossbeam 113 of the aforementioned front rectangular frame 11 and the door panel may also be provided with a method such as Figure 4 , Figure 7 and Figure 10 The structure shown is described in the following document. Figure 4 , Figure 7 and Figure 10The front rectangular frame 11 has mounting holes at both ends of its top surface; the front rectangular frame 11 also has door panel adjusting parts 7 at both ends of its top surface; the door panel adjusting parts 7 include a compensating part 71 and a fixing part 72. The compensating part 71 has a waist-shaped hole 711, the length direction of the waist-shaped hole 711 is in the left-right direction; the waist-shaped hole 711 corresponds vertically to the mounting hole; the compensating part 71 is fixed to the front rectangular frame 11 by fasteners 73 passing through the waist-shaped hole 711 and the mounting hole in sequence; the thickness of the compensating part 71 gradually decreases from the inside to the outside in the vertical direction; the fixing part 72 is connected to the compensating part 71 and extends forward of the front rectangular frame 11; the fixing part 72 is rotatably connected to the top surface of the door panel.

[0119] Specifically, the left edge of the top surface of the left door panel is fixed to the left edge of the top surface of the front rectangular frame 11 by a door panel adjusting piece 7; the right edge of the top surface of the right door panel is fixed to the right edge of the top surface of the front rectangular frame 11 by another door panel adjusting piece 7.

[0120] Because the weight of the power module and energy storage device is much greater than that of the power distribution module, the right frame accounts for a larger proportion of the overall weight of the unit, causing the cabinet frame to tend to tilt to the right. If the front vertical beam 112 of the front rectangular frame 11 tilts slightly to the right, the left and right door panels will also tilt slightly to the right along with the front vertical beam 112. Since the front upper crossbeam 113 of the front rectangular frame 11 is still horizontal, that is, the left and right corners of the front upper crossbeam 113 are at the same height, the top surface of the left door panel will be higher on the left and lower on the right, and the top surface of the right door panel will also be higher on the left and lower on the right. Moreover, the left end of the left door panel and the right end of the right door panel are limited to the same height by the front upper crossbeam 113, which will cause the left end of the right door panel to be higher than the right end of the left door panel, resulting in a height difference between the left and right door panels.

[0121] When the left and right door panels are slightly tilted, the position of the door panel adjustment component 7 in the left and right directions can be adjusted to move the left and right door panels slightly to the left, so as to adjust the two tilted door panels back into place and reduce or avoid the height difference between the two door panels.

[0122] Specifically, since the compensation part 71 has a waist-shaped hole 711, the diameter of the waist-shaped hole 711 in the left and right direction is larger than the diameter of the mounting hole. Even if the position of the compensation part 71 is slightly adjusted, the waist-shaped hole 711 can be made to correspond to the mounting hole, without affecting the fixation of the compensation part 71.

[0123] Furthermore, since the thickness of the compensation part 71 gradually decreases from the inside to the outside in the vertical direction, the compensation part 71 can be considered as a wedge-shaped plate with a gradually changing thickness. For the left door panel adjusting part 7, after it moves to the left, the fixed height of the compensation part 71 increases, which correspondingly raises the right end of the top surface of the left door panel. For the right door panel adjusting part 7, after it moves to the left, the fixed height of the compensation part 71 decreases, which correspondingly lowers the left end of the top surface of the right door panel, thereby ensuring that the right end of the left door panel and the left end of the right door panel are basically the same height, solving the problem of height difference between the two door panels.

[0124] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
