Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a battery rack and energy storage equipment. Background Technology

[0002] Electrochemical energy storage, as an energy storage method, has been widely used in the new energy industry. Typical electrochemical energy storage uses battery packs as the energy storage medium and is applied in harsh natural environments in the form of containers. In order to install the battery packs, battery racks are often set up inside the container as a fixed frame, and then multiple battery packs are installed on the battery racks.

[0003] The existing battery racks inside energy storage containers are generally independent racks, not connected to the surrounding battery racks or the container as a whole, resulting in poor stability. Battery racks are mostly constructed from square tubing or welded sheet metal parts. Each rack holds one or more battery packs. The stacking of multiple battery packs makes the racks prone to deformation and collapse. Due to the poor vibration resistance of the racks, the battery packs are easily displaced during transportation, which can damage the rack's strength and reduce its stability, severely impacting the lifespan of the energy storage container. Furthermore, due to assembly issues, there are numerous fixing points for the battery packs within the rack, with some energy storage containers having as many as 12 to 15 fixing points, resulting in low installation efficiency. Because the battery packs are stacked in multiple layers within the rack, maintenance and replacement of the bottom battery pack requires disassembling the upper battery packs layer by layer, leading to low maintenance efficiency. Finally, since the battery packs are mostly fixed in a rigid connection without cushioning or protection, vibrations generated during transportation can cause mechanical damage to the battery packs, seriously affecting the safety and reliability of the energy storage container's operation.

[0004] Therefore, there is an urgent need to provide a new type of battery rack and energy storage device to solve the above-mentioned technical problems in the existing technology. Utility Model Content

The front fixing member is used to fix the front panel of the battery pack, and the rear limiting member is used to engage the tail end of the battery pack. Multiple pressing members are correspondingly fixed to the multiple mounting frames, and each pressing member is positioned between adjacent rear limiting members at the same height. The pressing members apply vertical downward pressure to the tail end of the battery pack.

[0008] Optionally, the mounting frame includes two side beams and multiple crossbeams. The two side beams are fixed to two adjacent support frames. The multiple crossbeams are spaced apart along the first direction. The two ends of the crossbeams along the second direction are connected to the two side beams.

[0011] Optionally, the rear limiting member includes a limiting part and a buffer part. The limiting part extends along the second direction and is fixed to the crossbeam at the far end of the first direction among the plurality of crossbeams. The buffer part extends along the first direction, with one end fixed to the limiting part and the other end fixed to the side beam.

[0012] Optionally, the crimping member includes a connecting part and a fixing part. The connecting part extends along the height direction and is connected at one end to the crossbeam at the far end of the plurality of crossbeams along the first direction, and at the other end to the fixing part.

[0013] Optionally, the fixing part extends toward the direction close to the battery pack, and the fixing part and the last of the multiple crossbeams along the first direction form an opening receiving space, at least a portion of the tail end of the liquid cooling plate of the battery pack can be received and engaged in the opening receiving space.

[0014] Optionally, the fixing part is curved upward along the first direction and near the end of the battery pack and forms a guide flare.

[0027] The present invention will now be described in further detail 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 not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] The first direction described in this embodiment is: Figure 1 The X direction shown is the second direction. Figure 1 As shown, the Y direction, X direction and Y direction are perpendicular to each other, and both X direction and Y direction are horizontal directions perpendicular to the vertical direction.

[0032] like Figure 1 As shown, the battery rack includes at least two support frames 100, multiple mounting frames 200, and multiple pressing members 300. Adjacent support frames 100 are spaced apart and arranged opposite to each other. The multiple mounting frames 200 are spaced apart along the height direction, and their two ends along a second direction are correspondingly connected to adjacent support frames 100. The mounting frames 200 are used to support the battery pack. Each support frame 100 has a front fixing member 201 at one end along the first direction and a rear limiting member 202 at the other end. The rear limiting member 202 is fixed to the mounting frame 200. The front fixing member 201 is used to fix the front panel of the battery pack, and the rear limiting member 202 is used to engage the bottom of the rear end of the battery pack along the second direction. Multiple pressing members 300 are correspondingly fixed to the multiple mounting frames 200, and each pressing member 300 is disposed between adjacent rear limiting members 202 at the same height. The pressing members 300 are used to apply vertical downward pressure to the rear end of the battery pack.

[0033] The battery rack in this embodiment consists of at least two support frames 100, multiple mounting frames 200, and multiple pressing members 300. The mounting frames 200 serve to support the battery pack, and their two ends are respectively connected to two adjacent support frames 100, thus forming the main frame structure of the battery rack. When fixing the battery pack to the battery rack, a front fixing member 201 is provided at one end of the support frame 100 along the first direction to fix the front panel of the battery pack. A rear limiting member 202 is provided at the other end of the support frame 100 along the first direction to limit the bottom two ends of the rear end of the battery pack, thereby achieving the limitation and fixation of the battery pack in the first and second directions. The mounting frame 200 is also provided with pressing members 300, which apply downward pressure in the vertical direction to the tail end of the battery pack to achieve the limitation and fixation of the battery pack in the vertical direction. This enables the limitation of the battery pack in three directions, making the fixing method of the battery rack more reliable. This battery rack can reliably secure the battery pack, and the installation method is simple and convenient. It is easy to disassemble the battery pack for maintenance, and the battery rack has a stable structure, which can improve the safety and reliability of energy storage container transportation.

[0034] Furthermore, the aforementioned support frame 100 includes at least two side beams 110, a plurality of uprights 120 spaced apart along a first direction, and a plurality of reinforcing beams 130. Each upright 120 is connected to at least two side beams 110, and the two ends of each reinforcing beam 130 are correspondingly connected to two adjacent uprights 120. At least one reinforcing beam 130 is inclined. The support frame 100 is composed of side beams 110, uprights 120, and reinforcing beams 130. The two ends of each reinforcing beam 130 are correspondingly connected to two adjacent uprights 120, and at least one reinforcing beam 130 is inclined, thereby improving the mechanical strength of the support frame 100 and the battery rack and preventing the battery rack from tipping over or tilting.

[0035] Specifically, the aforementioned multiple reinforcing beams 130 are connected end to end in a sawtooth shape, providing longitudinal and lateral support to the support frame 100, further improving the mechanical strength of the support frame 100 and the battery rack.

[0036] Please continue to refer to this. Figure 1The aforementioned mounting frame 200 includes two side beams 210 and multiple crossbeams 220. The two side beams 210 are correspondingly fixed to two adjacent support frames 100. The multiple crossbeams 220 are spaced apart along the first direction. The two ends of each crossbeam 220 along the second direction are correspondingly connected to the two side beams 210. The rear limiting member 202 is fixed to the side beams 210. The pressing member 300 is fixed to the crossbeam 220 at the very end along the first direction. The mounting frame 200 adopts a frame structure composed of side beams 210 and crossbeams 220, rather than being a one-piece molded structure or a structure made of sheet metal, which can reduce the weight and processing difficulty of the mounting frame 200.

[0037] Optionally, the mounting frame 200 further includes a plurality of intermediate beams 230, which are spaced apart along the second direction. Each intermediate beam 230 is located between two adjacent side beams 210, and each intermediate beam 230 is fixed to a plurality of crossbeams 220 of the mounting frame 200. Thus, the side beams 210, intermediate beams 230, and crossbeams 220 constitute a crisscrossing frame structure along the first and second directions, resulting in higher mechanical strength and providing a more reliable and stable platform for supporting the battery pack.

[0038] In this embodiment, the side beam 210 is made of angle steel, and the cross beam 220 and the middle beam 230 are made of flat steel pipe. The top wall of the middle beam 230 is flush with the inner top wall of the side beam 210, providing a solid and stable support platform for carrying the battery pack.

[0039] Optionally, the two ends of the aforementioned crossbeam 220 along the second direction are fixed to the columns 120 of two adjacent support frames 100, and the multiple crossbeams 220 are arranged in a one-to-one correspondence with the multiple columns 120 of the support frames 100. Since the columns 120 and crossbeams 220 of the support frames 100 are arranged in a one-to-one correspondence, the columns 120 of the two support frames 100 and the corresponding crossbeams 220 of the multiple support frames 100 constitute a frame mechanism, which further improves the mechanical strength of the battery rack, can more stably support and fix the battery pack, avoid the battery pack from shaking and shifting within the battery rack, and improve the stability and reliability of the energy storage equipment using this battery rack during transportation.

[0040] like Figure 1 and Figure 2As shown, the crimping member 300 includes a connecting portion 310 and a fixing portion 320. The connecting portion 310 extends along the height direction and is connected at one end to the last of the multiple crossbeams 220 along the first direction, while the other end is connected to the fixing portion 320. The bottom wall of the fixing portion 320 can apply a vertically downward pressure to the tail end of the battery pack. In this embodiment, the crimping member 300 includes a connecting portion 310 and a fixing portion 320. The fixing portion 320 can apply downward pressure to the tail end of the bottom of the battery pack, thereby pressing and fixing the battery pack onto the mounting frame 200. The fixing method is reliable and can provide sufficient pressure to limit the vertical movement of the battery pack.

[0041] Optionally, the fixing part 320 extends towards the battery pack, and an opening is formed between the fixing part 320 and the rearmost of the plurality of crossbeams 220 along the first direction to form an accommodating space. At least a portion of the rear end of the liquid cooling plate of the battery pack can be accommodated and engaged in the opening. The opening formed between the fixing part 320 connecting part 310 and the top wall of the crossbeam 220 facilitates the insertion of the rear end of the liquid cooling plate at the bottom of the battery pack. This not only ensures reliable fixation of the battery pack but also utilizes the outward-protruding structure at the bottom of the battery pack, eliminating the need for an additional structure to fix the battery pack, simplifying the fixation structure, and reducing the weight of the battery rack and battery pack.

[0042] Furthermore, the aforementioned fixing part 320 curves upward along the first direction and near the end of the battery pack, forming a guide flare part 321. The guide flare part 321 has a flared structure, which can provide guidance when the tail end of the liquid cooling plate at the bottom of the battery pack is inserted into the opening space formed by the crimping member 300, thereby facilitating the fixing of the battery pack and improving installation efficiency.

[0043] In this embodiment, a buffer member 330 is provided on the bottom wall of the fixing part 320, and multiple reinforcing ribs 340 are connected between the connecting part 310 and the crossbeam 220. The buffer member 330 can reduce the impact of vibration on the battery pack during transportation when the energy storage device using the battery rack is transported, playing a shock absorption and buffering role, avoiding hard collisions between the battery pack and the battery rack, and improving safety and reliability.

[0044] Specifically, the fixing part 320 and the connecting part 310 are integrally formed, which makes the crimping member 300 have a certain degree of elasticity, thereby facilitating the insertion and installation of the battery pack. The elastic force can increase the downward pressure of the crimping member 300, resulting in a better fixing effect, which will not be elaborated here.

[0045] like Figure 1 and 3As shown, the aforementioned rear limiting member 202 includes a limiting part 2021 and a buffer part 2022. The limiting part 2021 extends along the second direction and is fixed to the end of the crossbeam 220 along the first direction among the plurality of crossbeams 220. The buffer part 2022 extends along the first direction, with one end fixed to the limiting part 2021 and the other end fixed to the side beam 210. Thus, the limiting part 2021 can apply a force along the first direction to the battery pack, thereby limiting the battery pack in the first direction. The buffer part 2022 can prevent the two ends of the battery pack along the second direction from directly colliding with the side beam 210. While providing a limiting and fixing function for the battery pack in the second direction, it also plays a buffering role, preventing damage to the battery pack caused by vibration during transportation.

[0046] In this embodiment, both the buffer section 2022 and the buffer element 330 are made of EVA (Ethylene Vinyl Acetate Copolymer) cushioning foam.

[0047] like Figure 4 As shown, the aforementioned front fixing member 201 is a threaded plate with threaded holes 2011. The front panel of the battery pack is fixed to the support frame 100 by fixing screws to the threaded holes 2011. This will not be described in detail here.

[0048] This embodiment also provides an energy storage device, which includes a battery rack as described in any of the above embodiments. This energy storage device has a more robust and reliable structure, can improve energy density, and has a longer service life. Specifically, this energy storage device is an energy storage container, which will not be described further here.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
