Description

Technical Field

[0001] The present application relates to the technical field of energy storage devices, and in particular to an energy storage cabinet and an energy storage cabinet. Background Art

[0002] As the core component of the energy storage system, the structural design and wiring management of the energy storage cabinet directly affect the stability, safety and sealing performance of the system.

[0003] In related technologies, energy storage cabinets have isolated battery and electrical compartments. The battery compartment houses the battery pack, while the electrical compartment houses the electrical equipment. The cabinet's top crossbeam typically features wiring harness holes, through which the wiring harnesses connecting the battery pack and electrical equipment pass, enabling centralized wiring.

[0004] However, the wiring harness is typically connected to connectors at both ends, which must be passed through the harness holes during wiring. The diameter of the connectors is much larger than the actual diameter of the harness wires. Therefore, when there are a large number of harnesses, such as multiple high-voltage and low-voltage harnesses, the harness holes are often much larger than the actual harness diameter. This can result in large gaps in the harness holes after assembly, hindering the sealing of the battery compartment and potentially affecting the safety of the entire energy storage cabinet.

DETAILED DESCRIPTION

[0073] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0075] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0076] Energy storage cabinets, also known as battery storage cabinets, are a core component of energy storage systems. Typically composed of battery modules, converters, power modules, and control systems, they store electrical energy and release it when needed, providing backup power and stabilizing grid voltage.

[0077] The interior of an energy storage cabinet is typically divided into a battery compartment and an electrical compartment. The battery compartment houses at least one battery pack, while the electrical compartment houses electrical equipment such as converters, power modules, and control systems. Generally speaking, the sealing requirements for the battery compartment are higher than those for the electrical compartment. In energy storage cabinet design, the battery packs in the battery compartment and certain electrical equipment in the electrical compartment must be connected via wiring harnesses to provide power.

[0078] In the related art, a wiring harness hole is generally opened on the cabinet structure between the battery compartment and the electrical compartment for the wiring harness to pass through, thereby realizing centralized wiring. Figure 1 As shown, each end of the wiring harness 4 is usually connected to a plug-in terminal 41. When wiring, the plug-in terminal 41 also needs to be passed through the wiring harness through-hole. The diameter of the plug-in terminal 41 is significantly larger than the wire diameter of the wiring harness 4, which results in the wiring harness through-hole needing to be relatively large. Especially when the number of wiring harnesses 4 is relatively large, for example, when it includes multiple high-voltage wiring harnesses and multiple low-voltage wiring harnesses, the size of the wiring harness through-hole is much larger than the actual wire diameter of the wiring harness 4, which results in a large gap between the wiring harness 4 and the inner wall of the wiring harness through-hole after the wiring harness 4 is assembled. This will cause the sealing performance of the battery compartment to deteriorate, greatly affecting the safety of the energy storage cabinet. In some energy storage cabinets with high sealing requirements, adapter sockets are usually used when the wiring harness is passed through the compartment, but this will greatly occupy the space inside the cabinet and lead to increased costs.

[0079] In response to the above problems, Figure 2 and Figure 3As shown, an embodiment of the present application provides an energy storage cabinet, including a cabinet body 1 and a closing assembly 2. The internal space of the cabinet body 1 includes a battery compartment 11 and an electrical compartment 12 separated from each other. For example, a partition 10 may be provided in the cabinet body 1, which divides the internal space of the cabinet body 1 into the battery compartment 11 and the electrical compartment 12. The partition 10 is provided with a through-compartment hole 131 that allows the wiring harness 4 to pass through. The battery compartment 11 and the electrical compartment 12 are connected through the through-compartment hole 131. The closing assembly 2 is mounted on the partition 10 and blocks or obstructs at least a portion of the through-compartment hole 131.

[0080] The energy storage cabinet provided in the embodiment of the present application is provided with a closing component 2 at the through-hole 131 of the crossbeam 13 of the cabinet body 1. When the wiring harness 4 to be connected passes through the through-hole 131, the closing component 2 is used to block and / or seal the gap between the wiring harness 4 and the inner wall of the through-hole 131, thereby reducing the connectivity between the battery compartment 11 and the electrical compartment 12, thereby improving the sealing performance of the battery compartment 11 of the energy storage cabinet, which is beneficial to improving the safety of the energy storage cabinet.

[0081] In some embodiments of the present application, Figure 2 and Figure 3 As shown, a crossbeam 13 is typically provided on the top wall of the cabinet body 1. This crossbeam 13 enhances the stability of the cabinet body 1, making it durable and sturdy. A partition 14 is also provided below the crossbeam 13 within the cabinet body 1. The top of the partition 14 is sealed to the crossbeam 13, and the other circumferential sides of the partition 14 are connected to the inner wall of the cabinet body 1, thereby dividing the interior space of the cabinet body 1 into a battery compartment 11 and an electrical compartment 12. The partition 10 includes the crossbeam 13 and the partition 14.

[0082] In some embodiments, the partition 10 is sealed to the cabinet body 1, and the through-hole 131 provided on the partition 10 is the only connection between the battery compartment 11 and the electrical compartment 12. The through-hole 131 can be located on the crossbeam 13, on the partition 14, or at the connection between the crossbeam 13 and the partition 14.

[0083] Optionally, the through-hole 131 is located on the crossbeam 13 and passes through the crossbeam 13 to connect the battery compartment 11 and the electrical compartment 12. By arranging the through-hole 131 on the crossbeam 13, the impact of the opening on the structural stability of the cabinet body 1 can be minimized, thereby ensuring the service life of the cabinet body 1.

[0084] The following describes in detail the structure of the energy storage cabinet provided in the embodiment of the present application, taking the through-hole 131 disposed on the crossbeam 13 as an example. Based on the following description, those skilled in the art can easily infer the corresponding situation when the through-hole 131 is disposed on other parts of the partition 10, such as the partition 14.

[0085] In some embodiments of the present application, Figure 3 As shown, the closure assembly 2 includes a shielding member 21 connected to the side wall 132 of the beam 13; see Figure 4 The orthographic projection of the shielding member 21 on the side wall 132 of the beam 13 is partially located within the orthographic projection of the through-hole 131 on the side wall 132. The side wall 132 of the beam 13 refers to the beam wall of the beam 13 facing the battery compartment 11 or the electrical compartment 12.

[0086] The axis of the through-hole 131 is usually perpendicular to the side wall 132 of the crossbeam 13. Accordingly, in order to block or seal the through-hole 131, the shielding member 21 can also be connected to the side wall 132 of the crossbeam 13 so as to block the opening of the through-hole 131. Figure 4 As shown, by making the orthographic projection of the shielding member 21 on the side wall 132 of the beam 13 located within the orthographic projection of the through-bin hole 131 on the side wall 132, that is, the shielding member 21 blocks a part of the opening of the through-bin hole 131, thereby reducing the exposed area of the through-bin hole 131 in the battery compartment 11 or the electrical compartment 12, thereby reducing the connectivity of the battery compartment 11 and the electrical compartment 12.

[0087] In practice, the covering member 21 can cover the entire free space of the through-cell hole 131 except for the space occupied by the wiring harness 4 passing therethrough as much as possible, thereby achieving the closure of the through-cell hole 131 and further achieving the sealing of the battery compartment 11.

[0088] It should be noted that in the embodiment of the present application, the shielding member 21 and the crossbeam 13 are connected in a movable or detachable manner, so that when wiring, the wiring harness 4 can smoothly pass through the through-hole 131 with a larger aperture without being interfered with by the shielding member 21; after the wiring harness 4 passes through the through-hole 131, the shielding member 21 is assembled or moved into place to achieve shielding of the empty space of the through-hole 131.

[0089] In order to improve the shielding effect of the covering member 21 on the empty space and close the through-bin hole 131 as much as possible, in some embodiments, the covering member 21 can be made in close contact with the wiring harness 4, and the part of the covering member 21 used for contact can be made of a flexible material, so that based on the pressure, the flexible material part is deformed to adapt to the shape of the wiring harness 4, thereby improving the sealing effect of the contact position between the covering member 21 and the wiring harness 4, and then improving the sealing effect of the through-bin hole 131.

[0090] In addition, after the shielding member 21 is installed, other components can be used to improve the sealing effect of the through-bin hole 131. For example, in some embodiments of the present application, Figure 13 and Figure 14As shown, the closure assembly 2 further includes a blocking member 22, which can be filled in the through-hole 131 to seal the gap between the inner wall of the through-hole 131 and the wiring harness 4 passing through the through-hole 131. In this way, the through-hole 131 can be sealed, thereby improving the sealing level of the battery compartment 11.

[0091] Optionally, the sealing member 22 may be sealing mud.

[0092] During implementation, to facilitate the installation of the sealing putty, the sealing putty can be filled on the side of the through-hole 131 away from the blocking member 22. For example, when the shielding member 21 is installed on the side wall 132 of the crossbeam 13 facing the electrical compartment 12, the sealing putty can be installed from the side wall 132 of the crossbeam 13 facing the battery compartment 11. In this way, the portion of the shielding member 21 extending into the opening of the through-hole 131 can be used to block the sealing putty, preventing the sealing putty from overflowing and falling out of the side opening of the through-hole 131 facing the electrical compartment 12 during the filling process.

[0093] In some embodiments of the present application, Figure 4 As shown, the shielding member 21 may include a first splicing portion 211 , a second splicing portion 212 , and at least two locking portions 213 . The first splicing portion 211 and the second splicing portion 212 may be connected to the beam 13 via the at least two locking portions 213 .

[0094] See also Figure 5 The first splicing portion 211 is provided with a first hole 2111, one side of the first hole 2111 extends to the first edge 2112 of the first splicing portion 211, thereby forming an open end on the first edge 2112. Figure 6 The second splicing portion 212 is provided with a second hole 2121, and one side of the second hole 2121 extends to the second edge 2122 of the second splicing portion 212, thereby forming an open end on the second edge 2122. Figure 4 and Figure 7 As shown, the second splicing portion 212 can be connected to the first splicing portion 211 in the first direction, thereby connecting the second hole 2121 and the first hole 2111. The first direction is parallel to the opening direction of the open end of the first hole 2111 and the opening direction of the open end of the second hole 2121.

[0095] When installing the first splicing part 211 and the second splicing part 212 on the side wall 132 of the beam 13, the open end of the first hole 2111 must be positioned opposite to the open end of the second hole 2121. In this way, when the first splicing part 211 and the second splicing part 212 are connected, the open end of the first hole 2111 will be connected to the open end of the second hole 2121, thereby realizing the connection between the first hole 2111 and the second hole 2121.

[0096] In some embodiments of the present application, Figure 4 As shown, the opening diameter of the first hole 2111 at the first edge 2112 is smaller than or equal to the diameter of the through-hole 131; the opening diameter of the second hole 2121 at the second edge 2122 is smaller than or equal to the diameter of the through-hole 131. This ensures that when the first and second splicing parts 211, 212 are joined, the shielding member 21 can shield the through-hole 131 in the width direction of the first and second splicing parts 211, 212.

[0097] It should be noted that the through-hole 131 provided on the crossbeam 13 is generally a round hole or a waist-shaped hole, for example Figure 4 The shown through-hole 131 is a waist-shaped hole. When the through-hole 131 is a circular hole, the diameter and length of the through-hole 131 refer to the diameter of the circular cross section of the circular hole; when the through-hole 131 is a waist-shaped hole, since the cross section of the waist-shaped hole includes two semicircles of equal size and a rectangle located between the two semicircles, the diameter of the through-hole 131 refers to the diameter of the semicircles, and the length of the through-hole 131 refers to the sum of the radii of the two semicircles and the length of the rectangle. For example, Figure 4 The diameter of the through-cell hole 131 shown is 50 mm, and the length of the through-cell hole 131 is 80 mm.

[0098] Optionally, the opening diameter of the first hole 2111 at the first edge 2112 is in the range of 30-40 mm, and the opening diameter of the second hole 2121 at the second edge 2122 is in the range of 30-40 mm.

[0099] In the embodiment of the present application, the length direction of the through-cell hole 131 is parallel to the length direction of the first splicing part 211 and the second splicing part 212 installed on the beam 13, and is parallel to the first direction; the width direction of the through-cell hole 131 is parallel to the width direction of the first splicing part 211 and the second splicing part 212 installed on the beam 13, and is perpendicular to the first direction and the axial direction of the through-cell hole 131 respectively.

[0100] In some embodiments, the first joint portion 211 and the second joint portion 212 are both plate-shaped, for example, made of sheet metal. During assembly, the first joint portion 211 and the second joint portion 212 are both attached to the side wall 132 of the beam 13 .

[0101] The first hole 2111 and the second hole 2121 respectively penetrate the first splicing portion 211 and the second splicing portion 212 along the plate thickness direction. Optionally, the first hole 2111 and the second hole 2121 are semicircular, semi-elliptical or U-shaped.

[0102] Figure 8 The process of connecting the first joint part 211 and the second joint part 212 is shown. Figure 8As shown in the top, middle, and bottom figures, during the docking process of the first splicing portion 211 and the second splicing portion 212, the shielding member 21 is sequentially positioned in a first position where the first splicing portion 211 and the second splicing portion 212 are spaced apart from each other, a second position where the first splicing portion 211 and the second splicing portion 212 are in contact with each other, and a third position where the first splicing portion 211 and the second splicing portion 212 overlap each other. From the second position onwards, it can be considered that the first splicing portion 211 and the second splicing portion 212 are in overlapping engagement.

[0103] Figure 8 The corresponding perspective and Figure 4 The corresponding viewing angles are the same, both facing the side wall 132 of the beam 13, and Figure 4 and Figure 8 In the figure, dashed lines and partially solid lines (e.g. Figure 8 The upper figure in FIG) shows the position of the through hole 131. Figure 8 As shown, the relative positions of the first splicing portion 211 and the second splicing portion 212 of the shielding member 21 can be adjusted according to actual needs (i.e., the space occupied by the wiring harness 4). Optionally, the length of the space enclosed by the first hole 2111 of the first splicing portion 211 and the second hole 2121 of the second splicing portion 212 in the first direction is greater than 0 mm and less than 80 mm, so that the space can accommodate the passage of a wiring harness 4 with a radial cross-sectional length of 0-80 mm and a radial cross-sectional width of 0-50 mm.

[0104] For example, when the number of wire harnesses 4 that need to pass through the through-hole 131 is relatively large, the shielding member 21 can be positioned at Figure 8 In the first position shown in the top figure, the first splicing portion 211 and the second splicing portion 212 do not contact each other, and there is a large gap between the first edge 2112 and the second edge 2122. The first splicing portion 211 and the second splicing portion 212 respectively clamp the wiring harness 4 passing through the through-bin hole 131 through the edge of the first hole 2111 and the edge of the second hole 2121, and the covering member 21 blocks a smaller part of the free space of the through-bin hole 131 to maximize the reduction of the exposed opening area of the through-bin hole 131.

[0105] When the number of wire harnesses 4 that need to pass through the through-hole 131 is relatively small, the shielding member 21 can be positioned at Figure 8The second position is shown in the middle figure, at this time, the first edge 2112 of the first splicing part 211 and the second edge 2122 of the second splicing part 212 are in contact with each other or the positive projections coincide with each other, the first hole 2111 and the second hole 2121 are connected, and the first splicing part 211 and the second splicing part 212 respectively clamp the wiring harness 4 passing through the through-bin hole 131 through the edge of the first hole 2111 and the edge of the second hole 2121, and the covering part 21 blocks a large part of the free space of the through-bin hole 131 to maximize the reduction of the exposed opening area of the through-bin hole 131.

[0106] When the number of wire harnesses 4 that need to pass through the through-hole 131 is smaller, the shielding member 21 can be positioned at Figure 8 In the third position shown in the bottommost figure, the first splicing portion 211 and the second splicing portion 212 overlap each other, the first hole 2111 and the second hole 2121 are connected and overlap in the second direction, and the first splicing portion 211 and the second splicing portion 212 respectively clamp the wire harness 4 passing through the through-bin hole 131 through the edge of the first hole 2111 and the edge of the second hole 2121. The shielding member 21 blocks more of the free space of the through-bin hole 131 to maximize the reduction of the exposed opening area of the through-bin hole 131. The second direction is perpendicular to the first direction and parallel to the axis direction of the first hole 2111 and the second hole 2121.

[0107] In some embodiments of the present application, the first splicing portion 211 and the second splicing portion 212 are both step-shaped structures. Figure 5 As shown, the first joint portion 211 includes a first step 2113 and a second step 2114 from bottom to top, the first edge 2112 is located on the side of the first step 2113 away from the second step 2114, and the first hole 2111 is located on the first step 2113. Figure 6 As shown, the second joint portion 212 includes a third step 2123 and a fourth step 2124 from bottom to top, the second edge 2122 is located on the side of the third step 2123 away from the fourth step 2124, and the second hole 2121 is located on the third step 2123. Figure 7 When the first splicing portion 211 and the second splicing portion 212 are docked, the first step 2113 can overlap with the third step 2123, thereby ensuring that the first splicing portion 211 and the second splicing portion 212 will not interfere with each other and warp before and after the first splicing portion 211 and the second splicing portion 212 are docked, and the thickness of the shielding member 21 is always consistent.

[0108] Continue to see Figure 6The first step 2113 has a first step surface, also referred to as the tread of the first step 2113; the second step 2114 has a second step surface, also referred to as the tread of the second step 2114. A first stop surface 2115 is provided between the first step 2113 and the second step 2114. The first stop surface 2115 is the vertical surface between the first step 2113 and the second step 2114, and the two sides of the first stop surface 2115 are connected to the first step surface and the second step surface respectively.

[0109] Similarly, see Figure 7 The third step 2123 has a third step surface, also referred to as the tread of the third step 2123; the fourth step 2124 has a fourth step surface, also referred to as the tread of the fourth step 2124. A second stop surface 2125 is located between the third step 2123 and the fourth step 2124. The second stop surface 2125 is the vertical surface between the third step 2123 and the fourth step 2124, and the two sides of the second stop surface 2125 are connected to the third step surface and the fourth step surface respectively.

[0110] When the first joint portion 211 and the second joint portion 212 are joined, the first stop surface 2115 on the first joint portion 211 can abut against the second edge 2122 of the second joint portion 212, and at the same time, the second stop surface 2125 on the second joint portion 212 can abut against the first edge 2112 of the first joint portion 211, thereby limiting the position of the first joint portion 211 and the second joint portion 212. It should be understood that when the first stop surface 2115 abuts against the second edge 2122 and the second stop surface 2125 abuts against the first edge 2112, the shielding member 21 is equivalent to being located at Figure 8 In the third position shown in the bottom figure, the shielding area of the blocking member 21 to the through-bin hole 131 reaches the maximum.

[0111] In some embodiments of the present application, Figure 5 As shown, the first hole 2111 is located on the first step 2113, that is, the distance between the first stop surface 2115 and the first edge 2112 is greater than or equal to the length dimension of the first hole 2111 in the first direction; the second hole 2121 is located on the third step 2123, that is, the distance between the second stop surface 2125 and the second edge 2122 is greater than or equal to the length dimension of the second hole 2121 in the first direction.

[0112] Therefore, by overlapping the first step 2113 and the third step 2123 with each other, the first hole 2111 and the second hole 2121 can be connected and overlapped in the second direction, thereby maximally shielding the through-bin hole 131 and reducing the exposed area of the through-bin hole 131 in the battery compartment 11 or the electrical compartment 12.

[0113] In some embodiments of the present application, Figure 5 As shown, two first through slots 2116 are further provided on the first splicing portion 211. The two first through slots 2116 are distributed on both sides of the first hole 2111, and the opening ends of the two first through slots 2116 are both located at the first edge 2112. Figure 6 As shown, two second through slots 2126 are further provided on the second splicing portion 212. The two second through slots 2126 are distributed on both sides of the second hole 2121, and the opening ends of the two second through slots 2126 are both located at the second edge 2122. Figure 7 As shown, when the first splicing portion 211 and the second splicing portion 212 are connected, the first through slot 2116 and the second through slot 2126 are connected. At least two locking portions 213 are installed through the first through slot 2116 and the second through slot 2126, thereby locking the first splicing portion 211 and the second splicing portion 212 on the beam 13.

[0114] like Figure 9 As shown, the first splicing portion 211 is provided with a first through slot 2116 above and below the first hole 2111, and the second splicing portion 212 is provided with a second through slot 2126 above and below the second hole 2121. The shielding member 21 includes four locking portions 213, each corresponding to a first through slot 2116 or a second through slot 2126.

[0115] See also Figure 9 Each locking portion 213 includes a stud 2131 and a nut 2132. The stud 2131 is fixed to the crossbeam 13, for example, by welding to the sidewall 132 of the crossbeam 13. The axis of the stud 2131 is parallel to the axis of the through-hole 131. When installing the first splicing portion 211 and the second splicing portion 212, the studs 2131 of the four locking portions 213 are passed through the first through-slot 2116 and / or the second through-slot 2126. The nuts 2132 are then threadedly connected to the portions of the studs 2131 that pass through the first through-slot 2116 and / or the second through-slot 2126, thereby locking the first splicing portion 211 and the second splicing portion 212 to the crossbeam 13.

[0116] For the shielding member 21 located at different positions, the installation positions of the four locking portions 213 relative to the first splicing portion 211 and the second splicing portion 212 are as follows: Figure 8When the shielding member 21 is in the first position, the studs 2131 of the two locking portions 213 corresponding to the first splicing portion 211 respectively pass through the two first through-slots 2116 and are locked on the first step 2113. The studs 2131 of the two locking portions 213 corresponding to the second splicing portion 212 respectively pass through the two second through-slots 2126 and are locked on the third step 2123. When the shielding member 21 is in the second position, the studs 2131 of the two locking portions 213 corresponding to the first splicing portion 211 respectively pass through the two first through-slots 2116 and are locked on the second step 2114 near the first step 2113. The studs 2131 of the two locking portions 213 corresponding to the second splicing portion 212 respectively pass through the two second through-slots 2126 and are locked on the fourth step 2124 near the third step 2123. When the shielding member 21 is in the third position, the studs 2131 of the two locking parts 213 corresponding to the first splicing part 211 respectively pass through the two first through grooves 2116 and the locking position is located on the second step 2114 away from the first step 2113, and the studs 2131 of the two locking parts 213 corresponding to the second splicing part 212 respectively pass through the two second through grooves 2126 and the locking position is located on the fourth step 2124 away from the third step 2123.

[0117] It should be understood that in some other embodiments of the present application, when the first step 2113 and the third step 2123 are long enough, the bolt of the locking portion 213 may also pass through the connected first through groove 2116 and the second through groove 2126 at the same time to simultaneously lock the first splicing portion 211 and the second splicing portion 212.

[0118] Optionally, at least two locking portions 213 are evenly arranged around the circumference of the through-bin hole 131 to ensure balanced force around the through-bin hole 131 and prevent stress concentration.

[0119] In some embodiments of the present application, Figure 5 As shown, the first through slot 2116 extends parallel to the first direction, and the extension length of the first through slot 2116 is greater than the length of the first hole 2111 in the first direction, and is greater than the distance between the first stop surface 2115 and the first edge 2112. Figure 6 As shown, the second through-slot 2126 extends parallel to the first direction, and the extension length of the second through-slot 2126 is greater than the length of the second hole 2121 in the first direction, and is greater than the distance between the second stop surface 2125 and the second edge 2122. In this way, the shielding member 21 can ensure that wire harnesses 4 of all sizes can pass through the first hole 2111 and the second hole 2121, and the gap between them.

[0120] In some embodiments of the present application, Figure 10As shown, the difference between the length of the first splicing portion 211 and the extended length of the first through-slot 2116 is greater than or equal to the thickness of the nut 2132; and the difference between the length of the second splicing portion 212 and the extended length of the second through-slot 2126 is greater than or equal to the thickness of the nut 2132. The thickness of the nut 2132 refers to the dimension between the inner and outer diameters of the nut 2132. If the nut 2132 is a flanged nut 2132, the thickness of the nut 2132 refers to the dimension between the outer and inner diameters of the flange.

[0121] Optionally, the length range of the first splicing part 211 and the second splicing part 212 is 56-65 mm, which satisfies the requirement that the first splicing part 211 and the second splicing part 212 can block the through-hole 131 in the first direction after being docked. After the first splicing part 211 and the second splicing part 212 are opened, they will not interfere with other structures on both sides, nor will they occupy too much space on the side wall 132 of the beam 13.

[0122] Optionally, the extension length of the first through slot 2116 and the second through slot 2126 in the first direction should be as large as possible to ensure that as many wire harnesses 4 as possible or with as large radial dimensions as possible can pass through them.

[0123] Optionally, the distance between the first stop surface 2115 and the first edge 2112 is in the range of 30-45 mm, the distance between the second stop surface 2125 and the first edge 2112 is in the range of 30-45 mm, and the thickness of the nut 2132 is 5 mm, thereby ensuring the locking strength of the nut 2132 .

[0124] In this way, it can be ensured that the locking member reaches a sufficiently large locking strength, avoiding the situation of inadequate locking and insufficient locking force, thereby ensuring the close fit between the shielding member 21 and the side wall 132 of the beam 13, and ensuring the sealing and shielding effect of the through-bin hole 131.

[0125] In some embodiments of the present application, Figure 11 As shown, the width of the first joint portion 211 is greater than the diameter of the through-hole 131, and the distance between the two first through-slots 2116 on the first joint portion 211 is greater than the diameter of the through-hole 131. The width of the second joint portion 212 is greater than the diameter of the through-hole 131, and the distance between the two second through-slots 2126 on the second joint portion 212 is greater than the diameter of the through-hole 131. Therefore, after the first and second joint portions 211 and 212 are assembled to the sidewall 132 of the crossbeam 13, the first and second through-slots 2116 and 2126 do not communicate with the through-hole 131, thereby preventing the through-hole 131 from being excessively exposed.

[0126] Optionally, the width of the first splicing portion 211 is in the range of 68-75 mm, and the width of the second splicing portion 212 is in the range of 68-75 mm. In this way, the first splicing portion 211 and the second splicing portion 212 can cover the through-hole 131 on the crossbeam 13 in the width direction after being connected.

[0127] Optionally, the first splicing portion 211 and the second splicing portion 212 have the same structure. Therefore, the first splicing portion 211 and the second splicing portion 212 can be manufactured using the same set of molds, which reduces mold costs and has better economy.

[0128] The energy storage cabinet provided in the embodiment of the present application may have an impact on the structural strength of the crossbeam 13 due to the through-hole 131 opened on the crossbeam 13, resulting in structural instability. To solve this problem, in some embodiments of the present application, such as Figure 9 and Figure 10 As shown, the shielding member 21 further includes a reinforcement portion 214, which is located between the nut 2132 and the first splicing portion 211 or the second splicing portion 212. The reinforcement portion 214 has screw holes 2141 at both ends. The two studs 2131 located on opposite sides of the through-hole 131 in the at least two locking portions 213 respectively pass through the screw holes 2141 at both ends of the reinforcement portion 214.

[0129] The reinforcement portion 214 is a rigid structural member, and the connection points between it and the locking portion 213 are rigid connection points. Because the two rigid connection points between each reinforcement portion 214 and the corresponding two locking portions 213 are located on both sides of the through-hole 131, the rigidity and strength of the beam wall around the through-hole 131 are increased, thereby making the crossbeam 13 structure more stable.

[0130] Furthermore, the reinforcing portion 214 can also improve the strength between the first through-slot 2116 and the edges of the first hole 2111 and the first splicing portion 211, as well as the strength between the second through-slot 2126 and the edges of the second hole 2121 and the second splicing portion 212. On this basis, the first through-slot 2116 on the first splicing portion 211 can be designed to be relatively close to the edges of the first hole 2111 and the first splicing portion 211, and the second through-slot 2126 on the second splicing portion 212 can be designed to be relatively close to the edges of the second hole 2121 and the second splicing portion 212. This reduces the overall size of the first splicing portion 211 and the second splicing portion 212, preventing them from occupying too much of the layout area on the side wall 132 of the crossbeam 13.

[0131] In addition, the reinforcing portion 214 can also play a role similar to a gasket, thereby increasing the compression strength between the overlapping portions of the first splicing portion 211 and the second splicing portion 212 and preventing the overlapping portions from warping.

[0132] In some embodiments of the present application, Figure 11 As shown, the orthographic projection of the reinforcement portion 214 on the side wall 132 of the beam 13 is located outside the orthographic projection of the through-hole 131 on the side wall 132, and at least partially overlaps with the orthographic projections of the corresponding first through-groove 2116 and second through-groove 2126 on the side wall 132 of the beam 13.

[0133] Among them, "the orthographic projection of the reinforcing portion 214 on the side wall 132 of the beam 13 is located outside the orthographic projection of the through-warehouse hole 131 on the side wall 132", which includes the situation where the outer contour of the orthographic projection of the reinforcing portion 214 on the side wall 132 of the beam 13 is connected with the outer contour of the orthographic projection of the through-warehouse hole 131 on the side wall 132, and also includes the situation where there is a gap between the orthographic projection of the reinforcing portion 214 on the side wall 132 of the beam 13 and the orthographic projection of the through-warehouse hole 131 on the side wall 132.

[0134] In this way, it is possible to avoid interference between the reinforcement portion 214 and the wiring harness 4 passing through the through-hole 131 after installation, thereby affecting wiring.

[0135] In some embodiments of the present application, for a structure that improves the strength of the beam 13, in addition to the above-mentioned reinforcement portion 214, the energy storage cabinet may also include a support ring 3, which is embedded in the interior of the through-bin hole 131, and the outer ring surface 31 of the support ring 3 is in contact with the inner wall of the through-bin hole 131.

[0136] The support ring 3 is a rigid structure. By embedding the support ring 3 in the through-hole 131, the mechanical strength of the crossbeam 13 at the through-hole 131 can be increased. The shape of the support ring 3 is adapted to the shape of the through-hole 131. For example, when the through-hole 131 is a circular hole, the support ring 3 is a circular ring; when the through-hole 131 is a waist-shaped hole, the support ring 3 is a waist-shaped ring.

[0137] The present application also provides an energy storage cabinet, the structure of which is as follows: Figure 2 and Figure 13 As shown, the energy storage cabinet includes the energy storage cabinet body described in the above embodiment.

[0138] In addition to the above energy storage cabinet, the energy storage cabinet also includes a battery pack 5, electrical equipment 6 and a wiring harness 4, such as Figure 2 As shown, the battery pack 5 is installed in the battery compartment 11 of the cabinet body 1 of the energy storage cabinet, the electrical equipment 6 is installed in the electrical compartment 12 of the cabinet body 1 of the energy storage cabinet, and the wiring harness 4 passes through the through-compartment hole 131 on the partition 10 of the energy storage cabinet and is electrically connected to the battery pack 5 and at least one electrical equipment 6 respectively.

[0139] The energy storage cabinet provided in the embodiment of the present application adopts the energy storage cabinet body described in the above embodiment, so the overall structure is more stable, and the sealing level of the battery compartment 11 can be improved, thereby making the energy storage cabinet have good safety.

This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein.
