These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0029] The terms “first,” “second,” “third,” “fourth,” etc., as used in this application (if applicable), are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0030] In this application, the terms "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplarily" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] In related technologies, when placing the battery pack into the test fixture, the connection between the battery pack and the test fixture is not secure. When the test fixture is moved to or from the test area, the battery pack may be damaged by impact due to bumps.

[0032] The present application provides a battery pack rack, which uses a battery pack bracket on the rack to fix the battery pack, and uses a fixing member and a first connecting member on the battery pack bracket to limit and fix the battery pack, thereby avoiding collision damage between the battery pack and the battery pack bracket during the transportation of the rack.

[0033] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0034] like Figures 1 to 5As shown in the figure, this application embodiment provides a battery pack rack, which includes a frame body 100 and at least one battery pack bracket 200. The battery pack bracket 200 is fixed to the frame body 100 and includes two connected fasteners 210. Each fastener is provided with a limiting groove 211, and the limiting groove 211 has an opening on one side in a first direction. The openings of the limiting grooves 211 on the two fasteners 210 are arranged opposite to each other and together form a insertion groove. The first ends of the two limiting grooves 211 communicate to form a first insertion interface, which is used for inserting a battery pack 10 into the insertion groove. The fastener 210 is provided with a fastener located at the first insertion interface for connecting the first end of the battery pack 10 to restrict the movement of the battery pack 10 in the first direction.

[0035] Through the above technical solution, the battery pack 10 can be inserted into the insertion slot formed on the battery pack bracket 200 along the first direction through the first insertion interface, and both sides of the battery pack 10 are respectively inserted into the two limiting slots 211. Through the cooperation of the two limiting slots 211, the battery pack 10 is limited in other directions besides the first direction. In addition, the first end of the battery pack 10 is also fixedly connected to the first direction, thereby limiting the battery pack 10 in the first direction. Thus, the battery pack 10 is fixed to the battery pack bracket 200 as a whole. The frame 100 provides an installation base for the battery pack bracket 200. When there are multiple battery pack brackets 200, the multiple battery pack brackets 200 can be fixed together by the frame 100. The transport frame 100 enables the overall transport of all battery pack brackets 200 and battery packs 10 mounted on the battery pack brackets 200. Furthermore, the limiting effect of the battery pack brackets 200 on the battery packs 10 reduces the risk of collision and damage between the battery packs 10 and the battery pack brackets 200 during the transport of the battery packs.

[0036] It should be noted that when there are multiple battery pack brackets 200, the multiple battery pack brackets 200 can be arranged at intervals along the height direction on the frame 100, thereby making full use of the space in the height direction and reducing the space occupied by the entire cluster in the horizontal direction. Thus, more clusters can be placed in the same ground area to hold more battery packs 10.

[0037] It is understandable that the aforementioned first direction is also the direction in which the battery pack 10 is inserted into the connector slot. The battery pack 10 is fixed to the frame 100 by means of fasteners 210. The two fasteners 210 connected together can be directly connected or indirectly connected through a bracket.

[0038] like Figure 3 and Figure 4As shown, for the specific structure of the fastener 210, in some optional embodiments, the fastener 210 includes a first support portion 212, a second support portion 213, a third support portion 214, and a fourth support portion 215. The first support portion 212, the second support portion 213, and the third support portion 214 are connected in sequence to form the aforementioned limiting groove 211. The first support portion 212 and the third support portion 214 are disposed opposite to each other, the second support portion 213 is disposed opposite to the opening, and the fourth support portion 215 and the first connector 220 are respectively fixed to the two ends of the first support portion 212 in the first direction. The fourth support portion 215 is used to connect the second end of the battery pack 10.

[0039] It can be understood that the first end and the second end of the battery pack 10 are the opposite ends of the battery pack 10. After the battery pack 10 is inserted into the insertion slot, one side of the battery pack 10 is located in the limiting slot 211. The first support part 212 can support the bottom of the battery pack 10, the third support part 214 can support and limit the top of the battery pack 10, the second support part 213 can support and limit the side of the battery pack 10, the fourth support part 215 can support and limit the second end of the battery pack 10, and the first connector 220 can support and limit the first end of the battery pack 10. This further restricts the movement of the battery pack 10 in the first direction.

[0040] like Figure 3 and Figure 4 As shown, optionally, in this embodiment, the first support portion 212, the second support portion 213, the third support portion 214, and the fourth support portion 215 are integrally formed and formed by bending a plate. Of course, in other embodiments, the first support portion 212, the second support portion 213, the third support portion 214, and the fourth support portion 215 can also be fixed by welding.

[0041] Optionally, the first support portion 212 and the second support portion 213 are arranged in parallel.

[0042] like Figure 3 and Figure 4 As shown, in order to facilitate the insertion of the battery pack 10 into the insertion slot, in some optional embodiments, the first connector 220 is disposed below the first support portion 212, so that the first connector 220 will not interfere with the insertion of the battery pack 10 into the insertion slot. Furthermore, the first end of the battery pack 10 can be connected to the first connector 220 through a rigid connector to realize the connection between the first battery pack 10 and the first connector 220.

[0043] Of course, in other embodiments, the first connector 220 may also be configured to be rotatably connected to the first support portion 212, so that during the process of inserting the battery pack 10 into the insertion slot, the first connector 220 can be rotated to the lower part of the first support portion 212, and after the battery pack 10 is inserted, one end of the first connector 220 can be rotated to the upper part of the first support portion 212 to connect with the first end of the battery pack 10.

[0044] In some alternative embodiments, the frame 100 has a receiving cavity in which the battery pack bracket 200 is disposed.

[0045] By providing a receiving cavity within the frame 100 and placing the battery pack bracket 200 within the receiving cavity, the frame 100 can protect the battery pack bracket 200 located within the receiving cavity. Optionally, the opening direction of the receiving cavity is the same as the opening direction of the insertion slot, so that the installation of the battery pack bracket 200 on the frame 100 and the installation of the battery pack 10 on the battery pack bracket 200 can both be completed in one direction, making it more convenient to use.

[0046] like Figure 3 and Figure 4 As shown, in some alternative embodiments, the first support portion 212 is provided with an extension portion 2121 at one end away from the fourth support portion 215, and at least part of the extension portion 2121 is located outside the receiving cavity.

[0047] It is understood that while the extension 2121 is located outside the receiving cavity, the extension 2121 is also located outside the first insertion interface. By setting the extension 2121, when the battery pack 10 is placed on the cluster rack, the battery pack 10 can be pre-positioned on the extension 2121, thereby making it easier to push the battery pack 10 from the extension 2121 through the first insertion interface into the insertion slot.

[0048] like Figure 3 and Figure 4 As shown, in some optional embodiments, the two fasteners 210 in the battery pack bracket 200 are respectively fixedly connected to the frame 100, and the two fasteners 210 in the battery pack bracket 200 are spaced apart, so that the extensions 2121 respectively provided on the two fasteners 210 are also spaced apart. The gap between the two fasteners 210 allows the forklift forks to pass through when raising or lowering. This makes it more convenient to move the battery pack 10 by forklift. Furthermore, the battery pack 10 can be directly placed on the extension 2121.

[0049] Optionally, the upper surface of the extension 2121 is parallel to the upper surface of the first support 212, thereby making the battery pack 10 easier to push into the insertion slot.

[0050] like Figure 3 and Figure 4 As shown, in some alternative embodiments, the third support portion 214 has an inclined first guide portion 2141 formed at the end away from the fourth support portion 215, and the distance between the first guide portion 2141 and the first support portion 212 gradually decreases along the first direction.

[0051] By providing the first guide portion 2141, the opening area of ​​the first connector can be increased, making it easier to push the battery pack 10 into the connector slot. Specifically, when the battery pack 10 is pushed in at an angle, if the battery pack 10 is in an angled state, the battery pack 10 will contact the first guide portion 2141 and enter the connector slot under the guidance of the first guide portion 2141.

[0052] It can be understood that the end of the third support 214 that is far away from the fourth support 215 refers to the end of the third support 214 that is close to the first insertion interface.

[0053] like Figure 3 and Figure 4 As shown, in some optional embodiments, the fourth support portion 215 is provided with a plug portion 2151, which is used to insert into the second end of the battery pack 10.

[0054] By providing the insertion part 2151, when the battery pack 10 is inserted into the insertion slot, the second end of the battery pack 10 can be inserted into the insertion part 2151, thereby further fixing the battery pack 10 through the insertion part 2151, and further preventing the battery pack 10 from colliding with the battery pack bracket 200 and being damaged during the transport of the cluster frame.

[0055] It is understood that a plug hole adapted to the plug part 2151 is provided at the second end of the battery pack 10 so that the plug part 2151 can be inserted into the plug hole.

[0056] like Figure 3 and Figure 4 As shown, optionally, in this embodiment, the plug-in portion 2151 and the fourth support portion 215 are integrally formed. Specifically, the end of the fourth support portion 215 away from the first support portion 212 is bent toward the first plug-in interface to form the plug-in portion 2151. In other embodiments, the plug-in portion 2151 and the fourth support portion 215 can be fixed by welding.

[0057] In some alternative embodiments, the second support portion 213 is provided with at least one second guide portion 2131 on the side facing the opening, and the second guide portion 2131 is configured to guide the insertion portion 2151 to be inserted into the battery pack 10.

[0058] By providing the second guide 2131, the battery pack 10 will be guided during the insertion of the battery pack 10 into the insertion slot. Under the joint limiting effect of the second guide 2131 on the two opposing fasteners 210, the position of the battery pack 10 can be corrected and adjusted, so that the battery pack 10 can be directly inserted into the insertion part 2151.

[0059] In this embodiment, the second guide portion 2131 protrudes from the side of the second support portion 213. This allows the second guide portion 2131 to guide the sidewall of the battery pack 10.

[0060] like Figure 3 and Figure 4 As shown, in some optional embodiments, there are multiple second guide portions 2131, which are arranged at intervals along the first direction. By using multiple second guide portions 2131 arranged at intervals, the guiding requirements can be met, and the weight of the battery pack bracket 200 can be reduced to a certain extent.

[0061] To facilitate the installation of the fastener 210 onto the frame 100, in some optional embodiments, the fastener 210 is provided with a plurality of second connectors 230, which are used for detachable connection with the frame 100. The second connectors 230 enable the connection and disassembly of the fastener 210 to the frame 100. Of course, in other embodiments, the fastener 210 can also be directly welded to the frame 100.

[0062] In some alternative embodiments, the fastener 210 is detachably connected to the frame 100 by bolts.

[0063] like Figure 1 , Figure 2 and Figure 5 As shown, in some optional embodiments, the cluster rack also includes a high-voltage box bracket 300 for placing the high-voltage box 20, and the high-voltage box bracket 300 is fixed to the frame 100.

[0064] A high-voltage box holder 300 is installed in the cluster rack, which allows the high-voltage box 20 to be placed on the cluster rack. This enables the battery pack 10 to be pre-connected to the high-voltage box 20 via conductive parts before testing, making testing of the battery pack 10 more convenient.

[0065] In addition, for energy storage systems with multiple battery pack clusters, each cluster includes multiple battery packs 10 and each cluster has an independent high-voltage box 20, the high-voltage box bracket 300 and battery pack bracket 200 on the cluster rack can respectively prevent the high-voltage box 20 and battery pack 10 of a cluster of energy storage systems, thereby making the test results closer to the results of the actual application scenario of battery pack 10 and high-voltage box 20 in the energy storage system.

[0066] like Figure 1 , Figure 2 and Figure 5 As shown, in some alternative embodiments, the high-voltage box bracket 300 is located above the battery pack bracket 200. Since all the connecting wires of the battery pack 10 converge at the high-voltage box 200, positioning the high-voltage box bracket 300 above the battery pack bracket 200 allows the high-voltage box 20 to be placed above the battery pack 10, facilitating wiring between the high-voltage box 20 and the battery pack 10.

[0067] Regarding the specific structure of the high voltage box bracket 300, in some optional embodiments, the high voltage box bracket 300 includes a base plate 310, a first limiting member 320 and a second limiting member 330. The upper surface of the base plate 310 is used to support the high voltage box 20, and a fixing part 311 is provided on the base plate 310. The fixing part 311 is used to connect the high voltage box 20.

[0068] The first limiting member 320 and the second limiting member 330 are both fixed to the upper surface of the base plate 310, and the first limiting member 320 and the second limiting member 330 are spaced apart so that the first limiting member 320, the second limiting member 330 and the base plate 310 together form a sliding groove. The sliding groove has a second insertion interface along the first direction, which is used for inserting the high voltage box 20 into the sliding groove.

[0069] By constructing a sliding groove, the high-voltage box 20 is pushed into the groove along a first direction. The groove guides both sides of the high-voltage box 20, allowing it to slide along a predetermined path. This enables the high-voltage box 20 to align with the fixing part 311, facilitating connection between them. Furthermore, after the high-voltage box 20 is connected to the fixing part 311, it can be fixed to the base plate 310, preventing damage from collisions during the transport of the cluster rack.

[0070] In some alternative embodiments, the length direction of the first limiting member 320 is parallel to the first direction, so that the sliding direction of the high voltage box 20 in the slide groove is also parallel to the first direction, that is, the high voltage box 20 slides into the slide groove along the first direction.

[0071] In some alternative embodiments, the fixing part 311 is a threaded hole, which is formed on the base plate 310. The high-voltage box 20 is provided with a through hole 2132 that matches the threaded hole. By using a bolt to pass through the through hole 2132 and then screw it into the threaded hole, the high-voltage box 20 and the base plate 310 are fixedly connected. Of course, in other embodiments, the connection between the high-voltage box 20 and the base plate 310 can also be achieved by a snap-fit ​​structure.

[0072] In some alternative embodiments, the end of the second limiting member 330 near the second insertion interface is cylindrical.

[0073] When the high-voltage box 20 is placed on the base plate 310 from top to bottom, it may not be able to fit precisely between the first limiting member 320 and the second limiting member 330, resulting in a longer placement time. However, in this embodiment, the end of the second limiting member 330 near the second insertion interface is made into a cylinder. The curved surface of the cylinder can guide the high-voltage box 20, allowing it to be easily and quickly placed into the slot.

[0074] Optionally, the second limiting member 330 includes a first part 331 and a second part 332. One end of the first part 331 and one end of the second part 332 are connected. The first part 331 is a cylinder. The second part 332 is provided with a second stop 333 at the end away from the first part 331. The second stop is used to limit the insertion depth of the high voltage box 20.

[0075] Optionally, a first stop 321 is provided at the end of the first limiting member 320 away from the second insertion interface. The first stop 321 and the second stop 333 cooperate to limit the insertion depth of the high voltage box 20.

[0076] In some alternative embodiments, the base plate 310 has a heat dissipation vent 312, which is located between the first limiting member 320 and the second limiting member 330.

[0077] It is understandable that, since the heat dissipation vent 312 is located between the first limiting member 320 and the second limiting member 330, the heat dissipation vent 312 is located within the slide groove. When the high-voltage box 20 is installed in the slide groove, the heat dissipation vent 312 can dissipate heat from the high-voltage box 20.

[0078] like Figure 1 and Figure 2 As shown, in some optional embodiments, the bottom of the frame 100 is provided with a first forklift hole 110 and a second forklift hole 120. The first forklift hole 110 is arranged along a first direction, and the second forklift hole 120 is arranged along a second direction, which is perpendicular to the first direction in the horizontal plane.

[0079] Both the first forklift hole 110 and the second forklift hole 120 can be inserted by the fork arms of a forklift, so as to carry the cluster rack by the forklift. Moreover, by setting the first forklift hole 110 and the second forklift hole 120, the cluster rack can be carried in different orientations, making the handling of the cluster rack faster.

[0080] As Figure 1 and Figure 2 shown, in some alternative embodiments, lifting lugs 130 are provided on the top of the frame body 100.

[0081] The lifting lugs 130 are used to connect the lifting equipment, so as to lift the cluster rack by the lifting equipment for handling.

[0082] In some alternative embodiments, there may be multiple lifting lugs 130, and the multiple lifting lugs 130 are distributed at intervals on the top of the frame body 100. During hoisting, at least one of the multiple lifting lugs 130 can be selected to be connected to the lifting equipment.

[0083] As Figure 2 shown, in some alternative embodiments, a cross-shaped beam 140 is provided on the side wall of the frame body 100. By means of the cross-shaped beam 140, the stiffness and load-bearing capacity of the frame body 100 can be improved, and the frame body 100 can be prevented from deforming.

[0084] As Figure 2 shown, in some alternative embodiments, the cross-shaped beam 140 includes a cross beam 141, a longitudinal beam 142 and a diagonal beam 143 arranged in the same plane. The cross beam 141 is perpendicularly connected to the longitudinal beam 142, and multiple diagonal beams 143 are distributed between the cross beam 141 and the longitudinal beam 142, so as to jointly construct the cross-shaped beam 140 with a "cross" structure by the cross beam 141, the longitudinal beam 142 and the diagonal beam 143.

[0085] As Figure 2 shown, in some alternative embodiments, a diagonal brace 144 is provided on the frame body.
