Description

Technical Field

[0001] The utility model relates to the field of energy storage boxes, in particular to a battery rack and an energy storage box. Background Art

[0002] When installing a battery pack in an energy storage container, it needs to be secured within the container. To achieve a higher energy density per unit volume, the battery packs are typically densely packed within the container, with minimal spacing between them. Installation is only accessible from the front, leaving no room for maneuvering elsewhere. Therefore, after installation, the battery pack is typically secured only at the front, failing to fully restrict its freedom of movement. This can cause vibrations during transport, leading to the pack shaking and easily loosening connectors. Furthermore, when installing the battery pack from the front, a push-in method is typically used, and the supporting surface is relatively large, making it difficult to ensure consistent roughness during manufacturing. Excessive surface roughness in certain areas can increase sliding friction when pushing the battery pack in, interfering with proper installation. Utility Model Content

[0030] The present invention discloses a battery rack and an energy storage box. Figure 1The energy storage box includes a box body 1 and the battery rack. The battery rack is arranged inside the box body 1 and is used to load the battery pack 4. The battery rack includes multiple groups of bracket columns 3 and multiple battery brackets 2. The multiple groups of bracket columns 3 are spaced apart along the length of the box body 1, and the ends of each group of bracket columns 3 are fixed to the top and bottom plates of the box body 1. Battery brackets 2 are arranged on opposite sides of two adjacent groups of bracket columns 3. The battery brackets 2 on the same side of the same group of bracket columns 3 are spaced apart along the length of the bracket columns 3.

[0031] See Figure 2 and Figure 3 The battery bracket 2 includes an integrally formed bracket body 21. The bracket body 21 includes a supporting plate 211 and a side connecting plate 212 that are connected to each other on the sides and perpendicular to each other. The supporting plate 211 is mainly used to support the battery pack 4, and the side connecting plate 212 is mainly used to fix the bracket body 21. In this embodiment, the right-angle space enclosed by the supporting plate 211 and the side connecting plate 212 is referred to as the inner side of the bracket body 21, so as to describe the corresponding positions of the remaining structures. The supporting surface of the bracket body 21, that is, the inner side of the supporting plate 211, that is, the side of the supporting plate 211 that contacts the battery pack 4 is provided with a protrusion 213. The protrusion 213 is an arc-shaped protrusion or a point-shaped protrusion. The point-shaped protrusion can be referred to. Figure 4 The protrusion 213 is used to reduce the contact area between the bottom of the battery pack 4 and the supporting surface, thereby reducing the impact of abnormal roughness areas generated during the manufacture of the bracket body 21 on the installation of the battery pack 4. The outer side of the side plate 212 is welded to the bracket column 3, or a mounting hole is opened in the side plate 212, and the side plate 212 is fixed to the bracket column 3 with bolts.

[0032] Through the above structure, a space for loading the battery pack 4 is formed between the two opposing battery brackets 2. When loading the battery pack 4, the battery pack 4 is pushed from the front end to the rear end of the battery bracket 2. Figure 2 The arrow in the figure indicates the direction in which the battery pack 4 is inserted. To facilitate insertion of the battery pack 4, two guides 217 are provided on the side of the side plate 212, away from the support plate 211. The guides 217 are located approximately in the middle of the side plate 212. The guides 217 include a first guide plate 2171 and a second guide plate 2172, connected in sequence along the direction in which the battery pack 4 is inserted. The second guide plate 2172 is integrally connected to the side of the side plate 212 and parallel to the support plate 211. The first guide plate 2171 is connected only to the second guide plate 2172 and is inclined relative to the second guide plate 2172, away from the support plate 211.

[0033] In order to restrict the loaded battery pack 4 from all directions, the battery bracket 2 of the present invention further includes a front limit mechanism 22, a side limit mechanism 23 and a rear limit mechanism 24 sequentially arranged on the bracket body 21 along the pushing direction of the battery pack 4.

[0034] The front end limiting mechanism 22 connects the front end of the bracket body 21 and the front end of the battery pack 4 by bolts. Figure 2 、 Figure 3 and Figure 5 In this embodiment, the front-end limiting mechanism 22 is a front-end limiting plate. A mounting plate 216 is provided downwardly from the front end of the support plate 211, perpendicular to the support plate 211. The mounting plate 216 is integrally formed with the entire bracket body 21. Bolt holes are provided at both ends of the front-end limiting plate. One end is connected to the mounting plate 216 via bolts and nuts, and the other end is connected to the battery pack 4 via bolts. The threaded connection between the front end limit plate and the mounting plate 216 allows the front end limit plate to rotate in a plane parallel to the mounting plate 216. Turning the bolt can adjust the direction of the front end limit plate and the position of the other end of the front end limit plate: when the front end limit plate is rotated so that the entire plate is below the plane where the support plate 211 is located, the front end of the battery bracket 2 has no limiting function, that is, it does not hinder the pushing in of the battery pack 4; after the battery pack 4 is completely pushed into the loading space, the front end limit plate is rotated to be perpendicular to the plane where the support plate 211 is located and the other end is located above the plane where the support plate 211 is located. At the same time, a nut is used to lock the other side of the mounting plate 216, and the front end limit plate and the battery pack 4 can be connected by bolts, thereby limiting the front end of the battery pack 4.

[0035] Combine Figure 2 、 Figure 3 、 Figures 6 to 8 The side limiter 23 is detachably connected to the bracket body 21 and gradually approaches the side edge of the battery pack 4 as the battery pack 4 is inserted until it contacts the battery pack 4. The side connecting plate 212 is provided with two sets of latches 214 and slots 215, sequentially arranged along the insertion direction of the battery pack 4. The latches 214 are chamfered right-angled and protrude from the inner side of the side connecting plate 212. The slots 215 and latches 214 are integrally formed with the side connecting plate 212 through a punching and pressing process. In this embodiment, the side limit mechanism 23 is a side limit plate comprising two end plates 231 and an intermediate plate 232. The two end plates 231 are located in the same plane, and the intermediate plate 232 is connected to the two end plates 231 at an angle relative to the plane of the end plates 231. The width of the intermediate plate 232 is greater than the width of the end plates 231. That is, the intermediate plate 232 is flush with the end plates 231 on one side and protrudes from the end plates 231 on the other side. This ensures that when the two end plates 231 are respectively inserted into the corresponding slots 215 and one side is inserted into the inner side of the buckle 214, the opposite side of the intermediate plate 232 can directly contact the surface of the support plate 211, thereby securing the side limit plate to the bracket body 21. It should be noted that when installing the side limit plate, the intermediate plate 232 should be tilted in a direction that gradually approaches the battery pack 4 along the direction in which the battery pack 4 is inserted.

[0036] The installation position of the side limit mechanism 23 is close to the tail limit mechanism 24, and one end is located below the tail limit mechanism 24 to cooperate with the use of the tail limit mechanism 24. Figure 2 、 Figure 3 、 Figures 9 to 11 The tail end stop mechanism 24 is located near the rear end of the bracket body 21 and includes a first and second stopper sections that move synchronously. The rear end of the battery pack 4 can push the second stopper section, driving the first stopper section to press the battery pack 4 downward. A first axial hole 218 is defined in the side plate 212, and a second axial hole 243 is defined in the tail end stop mechanism 24. The second axial hole 243 and the first axial hole 218 are connected by a rotating shaft 25, hingedly connecting the tail end stop mechanism 24 to the side plate 212. The rotating shaft 25 also has baffles at both ends to prevent the tail end stop mechanism 24 from falling off the bracket body 21. The second shaft hole 243 is flanked by a first-stage limiting portion and a second-stage limiting portion. In this embodiment, the tail end limiting mechanism 24 is an integrally formed structure. The first-stage limiting portion includes a first connecting plate 242 and an upper pressure plate 241, and the second-stage limiting portion includes a second connecting plate 244 and a rear baffle 245. The upper pressure plate 241, the first connecting plate 242, the second connecting plate 244, and the rear baffle 245 are sequentially connected. The upper pressure plate 241 and the rear baffle 245 are perpendicular to the plane of the first connecting plate 242 and the second connecting plate 244. The first connecting plate 242 and the second connecting plate 244 form an obtuse angle, and the length of the second connecting plate 244 is greater than that of the first connecting plate 242. Under normal conditions, due to the action of force, the upper pressure plate 241 is at a higher level, and the rear baffle 245 is at a lower level.

[0037] During the pushing process of the battery pack 4, the tail end of the battery pack 4 passes through the front end limit mechanism 22, the guide portion 217, and the side limit mechanism 23 in sequence until it reaches the tail end limit mechanism 24: As mentioned above, when the battery pack 4 is pushed in, the front end limit mechanism 22 is not activated, and the guide portion 217 plays a basic guiding and upper and lower limiting role for the battery pack 4; combined with Figure 12 After the tail end of the battery pack 4 passes through the side limiting mechanism 23, the left and right sides of the entire battery pack 4 are restricted by the side limiting mechanism 23; the tail end of the battery pack 4 pushes the rear baffle 245, combined with Figure 13 The rear baffle 245 drives the upper pressing plate 241 to rotate synchronously along the red arrow in the figure until the upper pressing plate 241 presses the side of the battery pack 4 and the battery pack 4 cannot be pushed in any further. Figure 14 , thereby restricting the rear side and the upper and lower sides of the battery pack 4; at this time, the battery pack 4 is completely pushed into the loading space, and it is only necessary to rotate the front end limiting mechanism 22 to connect the front end of the battery pack 4 and the bracket body 21 through bolts to restrict the front side of the battery pack 4, while further restricting the left and right freedom of the battery pack 4.

[0038] In summary, the present invention completely limits the freedom of movement of the battery pack 4 in six directions, including up and down, left and right, and front and back, by setting limiting mechanisms at different positions of the bracket body 21, thereby making the installation of the battery pack 4 more stable; and the connection between the bracket body 21 and each limiting mechanism is non-welded, which reduces the influence of thermal deformation during welding and ensures the straightness of the bracket body 21.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
