Description

Technical Field

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

[0002] Energy storage containers are generally composed of battery racks, battery packs, and other accessories. Battery packs typically need to be assembled onto the battery racks so that the support frames within the racks provide stable support and fixation. However, existing battery packs are generally quite heavy, causing uneven stress on the support frames when the battery packs are moving in and out of the racks, especially in the area near the opening. During the process of the battery pack not being fully inserted into or removed from the rack, this area near the opening has to bear the weight of the entire battery pack, making the battery rack highly susceptible to damage or deformation during battery pack assembly. Utility Model Content

[0003] This application provides a battery holder that can prevent the support bracket from deforming or being damaged due to uneven force.

[0004] A battery rack according to an embodiment of this application includes: a frame body with an opening; a support bracket disposed within the frame body, the support bracket having a main support surface for supporting a battery pack; and an auxiliary crossbeam disposed on the outside of the support bracket near the opening, the auxiliary crossbeam having an auxiliary support surface, the auxiliary support surface being flush with or higher than the main support surface, the auxiliary support surface providing support for the battery pack when it enters or exits the opening.

[0005] On this battery rack, the auxiliary support surface of the auxiliary crossbeam is flush with or higher than the main support surface of the support bracket, so that the auxiliary crossbeam can act as a load-bearing beam when the battery pack enters or exits the rack through the opening, thus preventing the support bracket from deforming or being damaged due to uneven stress.

[0006] According to some embodiments of this application, the auxiliary support surface is 0-2 mm higher than the main support surface.

[0007] According to some embodiments of this application, two lintels are also included, and the auxiliary crossbeam is detachably connected between the two lintels.

[0008] According to some embodiments of this application, the door beam is provided with a mounting conical groove, and both ends of the auxiliary crossbeam are provided with end shafts that are detachably connected to the mounting conical groove; in the height direction of the door beam, the cross-sectional size of the mounting conical groove decreases from top to bottom.

[0009] According to some embodiments of this application, the support bracket includes two guide rails disposed within the frame body; each guide rail includes a horizontal section extending along the clustering direction, and the two horizontal sections form the main support surface.

[0011] According to some embodiments of this application, a fixing hole is also included, which is formed in the horizontal section and is used to cooperate with a fastener to fix the battery pack.

[0012] According to some embodiments of this application, it further includes a limiting baffle and a wedge block, both of which are disposed on the guide rail; the wedge block and the limiting baffle are arranged sequentially along the direction away from the auxiliary crossbeam, and are used to jointly abut against the battery pack to limit the clustering direction.

[0013] According to some embodiments of this application, a height limiting plate is also included. The height limiting plate is disposed on the guide rail, and the height limiting plate and the horizontal segment are spaced apart to form a limiting gap for limiting the height of the battery pack.

[0014] Based on the same inventive concept, this application also proposes an energy storage container, including a container body and a battery rack as described above, wherein the battery rack is assembled inside the container body.

[0015] In summary, the battery rack provided in this application has the following technical advantages:

[0016] The auxiliary support surface of the auxiliary crossbeam is flush with or higher than the main support surface of the support bracket, so that the auxiliary crossbeam can act as a load-bearing beam when the battery pack enters or exits the frame through the opening, thus preventing the support bracket from deforming or being damaged due to uneven stress.

[0024] To better understand and implement this application, the technical solutions in this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] In the description of this application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, 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 application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0027] See Figure 1 This application discloses a battery rack. The battery rack includes a frame body 1, a support bracket 2, and an auxiliary crossbeam 3. In some embodiments, the frame body 1 has an opening 11, the support bracket 2 is disposed within the frame body 1, and the support bracket 2 has a support plane 21, the main support plane 21 being used to support a battery pack; the auxiliary crossbeam 3 is disposed on the outside of the support bracket 2 near the opening 11, and the auxiliary crossbeam 3 has an auxiliary support surface, the auxiliary support surface being flush with or higher than the main support surface 21, the auxiliary support surface being used to provide support when the battery pack enters and exits the opening. Thus, by having the auxiliary support surface of the auxiliary crossbeam 3 flush with or higher than the main support surface 21 of the support bracket 2, the auxiliary crossbeam 3 can act as a load-bearing beam when the battery pack enters and exits the frame body 1 through the opening, preventing the support bracket 2 from deforming or being damaged due to uneven stress.

[0028] In some embodiments, the height difference between the auxiliary support surface and the support plane 21 should not be too large. If the height difference is too large, during the process of the battery pack entering the frame 1, when the battery pack leaves the auxiliary support surface, it may fall due to the excessive height difference, causing a violent collision between the battery pack and the support bracket 2, seriously affecting the safety of the equipment and the battery pack. Preferably, the auxiliary support surface is 0-2mm higher than the support plane 21. In this way, by limiting the height difference between the auxiliary beam 3 and the support plane 21 to 0-2mm, the excessive height difference between the auxiliary support surface and the support plane 21 is avoided, thereby preventing a violent collision between the battery pack and the support bracket 2.

[0029] See Figure 1 , Figure 3 and Figure 5 In some embodiments, two door beams 4 are also included, and the auxiliary crossbeam 3 is detachably connected between the two door beams 4. In this way, the two door beams 4 serve as support mechanisms for the auxiliary crossbeam 3, thereby making full use of the components on the battery rack and optimizing manufacturing costs. Preferably, by detachably connecting the auxiliary crossbeam 3 between the two door beams 4, the auxiliary crossbeam 3 can be removed from the door beams 4 after the battery pack is assembled or disassembled, allowing the door beams 4 to function normally for opening and closing the door. When the battery pack needs to be assembled or disassembled again, the auxiliary crossbeam 3 can be reassembled onto the door beams 4, and it can be quickly replaced if it is deformed or damaged.

[0030] See Figure 1 , Figure 3 and Figure 5In some embodiments, the door beam 4 and the auxiliary crossbeam 3 can be detachably connected by means of snap-fit ​​connection and threaded connection. Preferably, the door beam 4 has a mounting conical groove 41, and both ends of the auxiliary crossbeam 3 are provided with end shafts 31 that cooperate with the mounting conical groove 41. In the height direction of the door beam 4, the cross-sectional size of the mounting conical groove 41 decreases from top to bottom. In this way, the auxiliary crossbeam 3 is fixed to the door beam 4 by cooperating with the mounting conical groove 41 and the end shafts 31. The cross-sectional size of the mounting conical groove 41 decreases from top to bottom in the height direction of the door beam 4, so that the upper end of the mounting conical groove 41 is the area with the largest cross-section, driving the end shaft 31 to extend into or out of the mounting conical groove 41 from the upper end of the mounting conical groove 41. When the end shaft 31 extends into the upper end of the mounting conical groove 41, under the action of the gravity of the auxiliary crossbeam 3, the end shaft 31... The auxiliary beam 3 moves downwards to engage the mounting tapered groove 41 with the end shaft 31, forming a stable connection. When the auxiliary beam 3 needs to be removed from the door beam 4, simply pull the auxiliary beam 3 upwards. The end shaft 31 moves upwards along with the auxiliary beam 3 to the upper end of the mounting tapered groove 41, allowing the end shaft 31 to be removed from the mounting tapered groove 41. This enables the auxiliary beam 3 to be removed from the door beam 4, achieving quick assembly and disassembly between the auxiliary beam 3 and the door beam 4.

[0031] See Figure 1 , Figure 2 and Figure 4 In some embodiments, the support bracket 2 includes two guide rails 22, which are disposed within the frame 1; the guide rails 22 include horizontal sections 221, which extend along the clustering direction, and the two horizontal sections 221 form the main support surface 21. Preferably, the main support surface 21 is formed by two horizontal segments 221 extending along the clustering direction, so that the horizontal segments 221 support the batteries assembled on the frame 1. In this embodiment, the horizontal segments 221 support the bottom of the battery pack, forming the support plane 21 for supporting the battery pack. In this way, the battery pack can slide on the horizontal segments 221, so that the battery panels can be assembled onto or off the frame 1. Specifically, when assembling or disassembling the battery pack on the battery rack, the auxiliary crossbeam 3 is set on the outer side of the horizontal segment 221 near the opening 11. The auxiliary support surface of the auxiliary crossbeam 3 is flush with or higher than the main support surface 21 formed by the horizontal segment 221, so that the auxiliary crossbeam 3 can act as a load-bearing beam when the battery pack enters or exits the horizontal segment 221 through the opening, avoiding deformation or damage to the horizontal segment 221 due to uneven stress.

[0032] See Figure 1 , Figure 2 and Figure 4 In some embodiments, the support bracket 2 further includes a bracket 223, through which the horizontal section 221 is fixedly connected to the frame 1; a vertical section is connected to the side of the horizontal section 221 away from the bracket 223, and the vertical section is fixedly connected to the frame 1. Optionally, the horizontal section 221 is fixedly connected to the bracket 223 by welding, bolting, or other means, and the bracket 223 is fixedly connected to the frame 1 by welding, bolting, or other means, so that the frame 1 provides support to the horizontal section 221 through the bracket 223, thereby improving the load-bearing capacity of the horizontal section 221. Optionally, the horizontal section 221 and the vertical section are integrally formed. The vertical section is fixedly connected to the frame 1 by welding, bolting, or other methods. Optionally, the bracket 223, the horizontal section 221, and the vertical section are arranged along the height direction of the frame 1, so that the horizontal section 221 can be fixedly connected to the frame 1 on both sides along the height direction of the frame 1. This drives the frame 1 to provide sufficient support and fixation to the horizontal section 221, fully optimizing the load-bearing capacity of the horizontal section 221, so that the battery pack can be reliably fixed in the frame 1.

[0033] Furthermore, the frame 1 can be a box structure formed by several plates and having an opening 11, or a frame structure formed by several longitudinal beams and having an opening 11, or a frame structure formed by several plates and several longitudinal beams. In this embodiment, the frame 1 is composed of several longitudinal beams. Optionally, four longitudinal beams are arranged at intervals along the clustering direction. Optionally, all four longitudinal beams are fixedly connected to the vertical section 222. The vertical section 222 is connected to the upper end face of the horizontal section 221, and a bracket 223 is fixedly connected to each of the four longitudinal beams. The lower end face of the horizontal section 221 is fixedly connected to the bracket 223.

[0034] See Figure 1 and Figure 4 In some embodiments, a fixing hole 5 is also included. The fixing hole 5 is formed in the horizontal segment 221 and is used to cooperate with a fastener to fix the battery pack. Optionally, the fastener can be a bolt, screw, pin, or clip, etc. In this embodiment, when the battery pack slides to the assembly position along the clustering direction on the horizontal segment 221, the fastener can cooperate with the fixing hole 5 to fix the battery pack in the assembly position, so that the battery pack is locked on the horizontal segment 221. Optionally, the rod of the fastener can first pass through the hole in the battery pack and then cooperate with the fixing hole 5 to lock the battery pack on the horizontal segment 221.

[0035] See Figure 1 and Figure 4 In some embodiments, a limiting baffle 6 and a wedge block 7 are also included, both of which are disposed on the guide rail 22. The wedge block 7 and the limiting baffle 6 are arranged sequentially along the direction away from the auxiliary crossbeam 3, and are used to jointly abut against the battery pack to limit the clustering direction. Optionally, the limiting baffle 6 is disposed at the end of the guide rail 22 away from the opening, and the wedge block 7 is disposed above the horizontal section 221. When the battery pack slides on the horizontal section 221 along the clustering direction to the assembly position, the battery pack can simultaneously abut against the limiting baffle 6 and the wedge block 7, so that the limiting baffle 6 and the wedge block 7 jointly limit the battery pack in the clustering direction.

[0036] Optionally, the wedge block 7 may also be provided with an abutting slope for abutting with the battery pack. Optionally, the distance between the end of the abutting slope near the auxiliary crossbeam and the horizontal segment 221 is greater than the distance between the end of the abutting slope away from the auxiliary crossbeam and the horizontal segment 221. That is, the abutting slope is inclined downward along the clustering direction to increase the contact area between the wedge block 7 and the battery pack. Optionally, a buffer layer may also be provided on the abutting slope. The buffer layer is made of elastic material and is used to buffer the wedge block 7 and the battery pack to prevent collision.

[0037] See Figure 1 and Figure 4 In some embodiments, a height limiting plate 8 is also included. The height limiting plate 8 is disposed on the guide rail 22, and the height limiting plate 8 and the horizontal segment 221 are spaced apart to form a limiting gap 81 for limiting the height of the battery pack. Preferably, when the battery pack moves along the clustering direction on the horizontal segment 221, the battery pack is driven into the limiting gap 81, so that the limiting gap 81 limits the position of the battery pack in the height direction, ensuring that the battery pack is fixed on the horizontal segment 221 and preventing the battery pack from displacing in the height direction.

[0038] In some embodiments, an energy storage container includes a container body and a battery rack as described above, the battery rack being assembled within the container body.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, during battery pack assembly, the auxiliary crossbeam 3 is pre-assembled between the two door beams 4, driving the auxiliary crossbeam 3 to be positioned on the outside of the support bracket 2 near the opening 11. The auxiliary support surface of the auxiliary crossbeam 3 is flush with or higher than the main support surface 21 of the support bracket 2, so that the auxiliary crossbeam 3 can act as a load-bearing beam when the battery pack enters the frame 1 through the opening, preventing the support bracket 2 from deforming or being damaged due to uneven stress. Then, the battery pack is driven to move along the clustering direction on the horizontal section 221, and by driving the battery pack into the limiting gap 81, the limiting gap 81 limits the position of the battery pack in the height direction, preventing displacement of the battery pack in the height direction. When the battery moves to the assembly position, the limiting baffle 6 and the... The wedge block 7 abuts against the battery pack simultaneously, jointly limiting the battery pack's entry direction. Then, the fasteners engage with the fixing holes 5 to fix the battery pack in the assembly position, locking it onto the horizontal section 221. This completes the assembly of the battery pack onto the frame 1. The auxiliary beam 3 is then removed from the door beam 4 so that the door beam 4 can be used for normal door opening and closing. When it is necessary to assemble or disassemble the battery pack again, the auxiliary beam 3 can be reassembled onto the door beam 4. When disassembling the battery pack, the fasteners are first removed from the fixing holes 5, and then the battery pack is driven through the opening to leave the frame 1. This allows the auxiliary beam 3 to act as a load-bearing beam when the battery pack leaves the frame 1 through the opening, preventing the support bracket 2 from deforming or being damaged due to uneven stress.
