Description

Technical Field

[0001] The utility model relates to the technical field of energy storage systems, and in particular to a battery pack bearing structure of an energy storage battery cabinet. Background Art

[0002] As a key component of battery energy storage systems, energy storage battery cabinets have been widely used in new energy, smart grids, energy-saving technologies, and other fields. The charging and discharging of batteries in energy storage cabinets can help reduce peak loads, improve power quality, serve as a backup power source, regulate frequency, and contribute to smart grid development.

[0003] In an energy storage battery cabinet, batteries are usually placed on the load-bearing rails on the energy storage battery cabinet. Currently, the battery pack load-bearing rails in existing energy storage battery cabinets still have the following problems:

[0004] 1. Most existing energy storage battery cabinets weld the load-bearing guide rails to the cabinet's supporting columns, causing severe deformation due to high-temperature welding. This makes it difficult to ensure the flatness of the load-bearing rails, preventing the bottom of the battery pack from making good contact with the rails during installation. During transportation, the battery pack is prone to swinging and shaking, which can damage the battery pack.

[0005] 2. The existing load rails in energy storage battery cabinets lack proper guide and limit structures, making battery pack installation difficult and increasing the complexity of the operation. For example, once the battery pack is placed in the load rail, it is difficult to center it. Furthermore, the battery pack is relatively heavy, typically weighing between 100 kg and 350 kg, making manual correction difficult. This can cause the fixing point of the battery pack to deviate significantly from the fixing hole during installation, affecting efficiency. Utility Model Content

[0008] As a further improvement of the present invention, the angle between the upper and lower limit folding edges and the front and rear limit folding edges is 93-100°.

[0009] As a further improvement of the present invention, the battery pack bearing guide rail includes an integrally formed bearing plate and a mounting plate, the battery pack guide is connected to the mounting plate, the load-bearing beam is slidingly fitted with the bearing plate, the battery pack fixing screw holes and the front and rear limit folding edges are respectively arranged on the bearing plate, a plurality of bolt connection holes are provided on the mounting plate, and a reinforcing folding edge is provided on the side of the mounting plate away from the bearing plate.

[0010] As a further improvement of the present invention, a first avoidance notch is provided at the front end of the mounting plate, and a second avoidance notch is provided on the mounting plate at a position corresponding to the battery pack fixing screw hole.

[0017] 2. The present invention limits the travel of the battery pack into the battery pack support rail by providing front and rear limit hems. Fixing bolts are then screwed into the battery pack fixing screw holes to limit the front and rear ends of the battery pack to the battery pack support rail, effectively preventing the battery pack from moving forward or backward.

The terms "first" and "second" in the specification and claims of this utility model or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0026] References to "embodiments" in this disclosure mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, an energy storage battery cabinet for carrying multiple battery packs includes a cabinet body 1, two parallel supporting columns 2 are respectively installed on the left and right side walls of the cabinet body 1, multiple battery pack supporting structures are evenly distributed on the supporting columns 2, and load-bearing beams 31 are respectively installed on the left and right sides of the battery pack 3.

[0029] The battery pack support structure includes battery pack support rails 4, which are fixedly connected to the support columns 2 via bolts and are symmetrically arranged in pairs within the cabinet 1. The battery pack support rails 4 are used to accommodate the battery packs 3. During use, the two load-bearing beams 31 of the battery pack 3 are placed on the two corresponding battery pack support rails 4, and the battery pack 3 is pushed to slide on the battery pack support rails 4, thereby placing the battery pack 3 into the cabinet 1. The battery pack support rails 4 are bolted to the support columns 2 to ensure the flatness of the battery pack support rails 4, thereby ensuring that the battery pack 3 can be placed stably on the battery pack support rails 4 and reducing the risk of damage to the battery pack 3.

[0030] The front end of the battery pack support rail 4 is provided with a battery pack fixing screw hole 41, and the rear end of the battery pack support rail 4 is provided with front and rear limit flanges 5, which can connect with the rear end of the load-bearing beam 31. During the installation of the battery pack 3, the battery pack 3 is pushed and slid on the battery pack support rail 4 until the load-bearing beam 31 connects with the front and rear limit flanges 5. At this point, the fixing screw holes on the battery pack 3 are exactly aligned with the battery pack fixing screw holes 41, and the battery pack 3 can be connected and fixed to the battery pack support rail 4 with screws. The provision of the front and rear limit flanges 5 can limit the travel of the battery pack 3 into the cabinet 1 and simultaneously determine the installation position of the battery pack 3 on the battery pack support rail 4.

[0031] The front and rear limiting flanges 5 are provided with upper and lower limiting flanges 6, which can be connected to the upper end surface of the load-bearing beam 31. The upper and lower limiting flanges 6 limit the upper end surface of the load-bearing beam 31, thereby preventing the battery pack 3 from swinging up and down, and keeping the battery pack 3 fixed on the battery pack support rail 4. This improves the installation stability of the battery pack 3 and reduces the risk of damage to the battery pack 3 due to swinging or shaking.

[0032] In this embodiment, the battery pack support rail 4, front and rear limit flanges 5, and upper and lower limit flanges 6 are integrally formed. This integrally formed structure reduces the number of installation steps, thereby improving assembly efficiency. In other embodiments, the battery pack support rail 4, front and rear limit flanges 5, and upper and lower limit flanges 6 can also be independent components that are fixed together by bolts or welding.

[0033] In order to facilitate pushing the battery pack 3 into connection with the front and rear limit folds 5, the angle between the upper and lower limit folds 6 and the front and rear limit folds 5 needs to be controlled at 93-100°, preferably 95°, and the height of the front and rear limit folds 5 is slightly larger than the thickness of the load-bearing beam 31; in the process of pushing the battery pack 3 into the cabinet 1, after the rear end of the load-bearing beam 31 is connected with the front and rear limit folds 5, the upper end surface of the load-bearing beam 31 is also connected with the upper and lower limit folds 6, and then the rear end of the battery pack 3 is limited by the front and rear limit folds 5 and the upper and lower limit folds 6, thereby reducing the possibility of the battery pack 3 loosening.

[0034] Each battery pack guide rail 4 is provided with a battery pack guide 7, each having a guide slope 71 that engages the side walls of the battery pack 3. In this embodiment, the height of the guide slope 71 gradually increases from the front end to the rear end of the battery pack guide rail 4. The battery pack guide 7 is used to guide the battery pack 3 as it is inserted into the cabinet 1. Specifically, when the battery pack 3 is placed on the battery pack guide rail 4 and inserted into the cabinet 1, if one of the side walls of the battery pack 3 engages the corresponding guide slope 71, the guide slope 71 gradually guides the battery pack 3 toward the center, thereby aligning the battery pack 3 as closely as possible after insertion. This allows the fixing screw holes on the battery pack 3 to align with the fixing screw holes 41. The provision of the battery pack guide 7 simplifies the installation of the battery pack 3, allowing it to be centered on the two corresponding battery pack guide rails 4.

[0035] In order to prevent the battery pack 3 from shaking after being installed in place, the inclination angle of the guide slope 71 needs to be controlled within 1-5°, preferably 3°.

[0036] like Figure 4 As shown, the battery pack bearing guide rail 4 includes an integrally formed bearing plate 42 and a mounting plate 43. The battery pack guide 7 is fixed to the mounting plate 43 by rivets. The bearing plate 42 is used to install the battery pack 3, and the load-bearing beam 31 can slide on the bearing plate 42, thereby pushing the battery pack 3 into or pulling out the cabinet 1; the battery pack fixing screw holes 41 and the front and rear limit folds 5 are respectively arranged on the bearing plate 42, and the mounting plate 43 is provided with a plurality of bolt connection holes 44 for connecting the support columns 2; the mounting plate 43 is provided with a reinforcing fold 8 on the side away from the bearing plate 42. By providing the reinforcing fold 8, the structural rigidity of the battery pack bearing guide rail 4 can be improved, thereby improving the bearing capacity of the battery pack bearing guide rail 4, reducing the load-bearing deformation, and improving the working stability.

[0037] A first clearance notch 45 is provided at the front end of the mounting plate 43. This allows for space for wiring the energy storage battery cabinet, facilitating wiring, reducing installation difficulty, and improving efficiency. A second clearance notch 46 is provided on the mounting plate 43 at a position corresponding to the battery pack fixing screw hole 41. This provides space for the installation tool to secure the fixing screws at the front end of the battery pack 3, avoiding interference and reducing installation difficulty and improving efficiency.

[0038] An L-shaped support block 9 is provided on the lower end surface of the mounting plate 43, and the L-shaped support block 9 is connected to the support column 2. The provision of the L-shaped support block 9 can increase the supporting force of the battery pack bearing rail 4, reduce the deformation of the load, and thus improve the stability of the battery pack bearing structure.

[0039] like Figure 5 As shown, the rear end of the battery pack guide 7 is provided with a tail stopper 72. The tail stopper 72 is integrally formed with the battery pack guide 7 and connected to one end of the guide slope 71. The tail stopper 72 is parallel to the direction in which the battery pack 3 is pushed into the cabinet 1, and the tail stopper 72 can contact the side wall of the battery pack 3. The tail stopper 72 is provided so that when the battery pack 3 is installed, the side wall of the battery pack 3 contacts the guide slope 71, ensuring surface contact between the battery pack 3 and the battery pack guide 7. This surface contact can reduce the damage to the battery pack 3 caused by the sharp corner of the guide slope 71. If the tail stopper 72 is not present, the guide slope 71 will have a sharp angle at the rear end, which can easily damage the battery pack 3.

[0040] The battery pack guide 7 is provided with an installation fixing plate 73, which is connected to the support column 2; by connecting the installation fixing plate 73 to the support column 2, the battery pack guide 7 is installed more firmly, thereby improving the structural stability.

[0041] The above-mentioned specific implementation manner is a preferred implementation manner of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
