Technical Field

[0001] The utility model relates to the technical field of energy storage equipment manufacturing, in particular to a shell assembly and energy storage equipment. Background Art

[0002] Energy storage containers are usually used to store energy storage devices and provide efficient heat dissipation for the energy storage devices. During the heat dissipation process, condensed water will be generated inside the energy storage container (in the related art, the heat dissipation of energy storage containers usually adopts a liquid cooling mode. If the liquid cooling pipeline leaks, there will be a large amount of liquid in the energy storage container, causing the operation of the energy storage device to be disturbed. In severe cases, it may even cause the energy storage device to be damaged and unable to work). In order to avoid the risk of bacteria breeding in the energy storage container or even corrosion of the energy storage device due to the long-term residence of the liquid, it is necessary to drain the liquid in time. Therefore, it is necessary to design a device that can discharge the liquid in the box in time. Utility Model Content

[0004] To achieve the above objectives, the present invention provides a housing assembly for an energy storage device, the housing assembly comprising:

[0005] The shell body defines a receiving space;

[0006] A mounting bracket is provided in the accommodation space, wherein the mounting bracket defines a plurality of mounting areas in the accommodation space, the mounting areas being arranged laterally with each other, and each mounting area being used to mount a corresponding group of battery modules;

[0010] or,

[0011] The second guide plate and the first guide plate are arranged in a stepped manner, and the setting position of the first guide plate is lower than the setting position of the second guide plate.

[0012] In some embodiments, the shell assembly also includes a main beam connected to the base plate and multiple secondary beams, the main beams are arranged at intervals along a first direction, and each secondary beam is arranged at intervals along a second direction and connected to the main beam, the second direction is perpendicular to the first direction, and the mounting bracket is connected to the secondary beam.

[0013] In some embodiments, the connection position of each of the secondary beams to the main beam is gradually lowered along the second direction toward the drain port.

[0014] In some embodiments, the bottom plate includes one first guide plate and a plurality of second guide plates, the second guide plates are adjacent to each other, and the second guide plates and the secondary beams are alternately arranged, and at least one second guide plate is adjacent to the first guide plate;

[0015] One of the secondary beams is defined as a first beam, wherein a connection position between the first beam and the main beam is lower than a connection position between the other secondary beams and the main beam, and the first beam is connected to the first guide plate and one of the second guide plates.

[0016] In some embodiments, one of two adjacent second guide plates is defined as a first plate and the other as a second plate, the position where the first plate is connected to the main beam is lower than the position where the second plate is connected to the main beam, and the highest point of the secondary beam connected to the first plate and the second plate is no higher than the lowest end of the first plate;

[0017] The highest point of the secondary beam connected to the first guide plate and the second guide plate is not higher than the lowest end of the second guide plate.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figures 1 to 4 The utility model provides a shell assembly 100, which includes a shell body 110 and a mounting bracket 120. The shell body 110 defines a accommodating space 111, which can be used to place components such as battery modules of energy storage equipment. The mounting bracket 120 is arranged in the accommodating space 111 inside the shell body 110, and divides the accommodating space 111 into a plurality of installation areas 121, which are arranged in sequence along the horizontal direction. Each installation area 121 can accommodate one or more groups of battery modules to ensure that the battery modules can be stably fixed in the shell body 110. A cooling device is also provided in the shell body 110, which can improve the heat dissipation efficiency of the battery module to ensure the safety and normal operation of the battery module. It should be noted that "horizontal" can be any direction perpendicular to the vertical direction. Specifically, "horizontal" can be the second direction Y, please refer to Figure 4 Along the second direction Y, the mounting bracket 120 divides the accommodating space 111 into six mounting areas 121 .

[0041] The shell body 110 also includes a bottom plate 112, which includes a first guide plate 1121 and a second guide plate 1122. The first guide plate 1121 is provided with a drain port 1123, while the second guide plate 1122 is designed to guide the liquid toward the first guide plate 1121. Through this structural design, when condensed water exists in the storage space 111 or a cooling pipe leaks, the liquid will first be guided by the second guide plate 1122 to the first guide plate 1121, and then discharged from the shell through the drain port 1123 on the first guide plate 1121. This layout not only helps prevent liquid from accumulating inside the shell and causing bacterial growth and corrosion of the structure in the storage space 111, but also effectively protects the electronic components in the shell from damage caused by liquid infiltration.

[0042] The first guide plate 1121 and the second guide plate 1122 correspond to at least two mounting areas 121. In some embodiments, the first guide plate 1121 and the second guide plate 1122 correspond to two mounting areas 121, with the first guide plate 1121 corresponding to one mounting area 121 and the second guide plate 1122 corresponding to another mounting area 121. In other embodiments, the first guide plate 1121 corresponds to one mounting area 121 and the second guide plate 1122 corresponds to multiple mounting areas 121. It should be noted that if the projections of the first guide plate 1121 and the second guide plate 1122 on the horizontal plane completely cover the projections of the two mounting areas 121 on the horizontal plane in the vertical direction, it can be considered that "the first guide plate 1121 and the second guide plate 1122 correspond to two mounting areas 121." In some embodiments, the first guide plate 1121 can be an independent whole plate, and similarly, the second guide plate 1122 can also be an independent whole plate. In other embodiments, the first guide plate 1121 may also be formed by splicing a plurality of plate structures, and the second guide plate 1122 may also be formed by splicing a plurality of plates. Compared to the related art, in order to ensure that the liquid in each area can be discharged and a drainage floor drain is set in each area, the second guide plate 1122 can guide the condensed water or leaked liquid generated in the multiple installation areas 121 to the first guide plate 1121, and discharge it through the drain port 1123 set in the first guide plate 1121. Thus, the number of drainage floor drains is reduced, thereby reducing the material cost of the shell assembly 100. In addition, the reduction in the number of drainage floor drains means the reduction in the number of drainage pipes connected to the drainage floor drains, so that the laying of the drainage pipes is more streamlined, reducing the difficulty of laying the drainage pipes while avoiding the pipes taking up too much space, thereby improving the assembly and maintenance convenience of the drainage pipes.

[0043] It is understood that in some embodiments, in order to enhance the adaptability of the housing assembly 100 to battery modules of different sizes or shapes, the design of the mounting bracket 120 can be adjusted according to actual needs. For example, the spacing between adjacent mounting areas 121 can be adjusted to accommodate different battery module sizes. In addition, additional sealing material can be added between the mounting bracket 120 and the base plate 112 to further improve the waterproof performance of the entire system. The housing body 110 can also be equipped with ventilation holes or other auxiliary structures to optimize internal air circulation and help dissipate heat, thereby extending the service life of the battery.

[0044] See also Figure 1 and Figure 2In some embodiments, the bottom plate 112 of the housing assembly 100 is provided with only one drain port 1123. This port is located on the first guide plate 1121, which, together with the second guide plate 1122, covers all mounting areas 121. Consequently, liquid generated in any mounting area 121 is ultimately guided by the second guide plate 1122 to the first guide plate 1121 and drained through the drain port 1123. This further reduces costs, simplifies the drainage system, reduces potential failure points, and improves the reliability and ease of maintenance of the overall structure.

[0045] It will be appreciated that in some embodiments, although there is only one drain port 1123, efficient drainage can be achieved by modifying the design of the first and second guide plates 1121, 1122. Furthermore, the surfaces of the first and second guide plates 1121, 1122 can be treated with special surface treatments, including but not limited to hydrophobic coatings, to reduce liquid adhesion and accelerate liquid flow. This enhances the performance of the energy storage device in extreme environments, and improves its safety and durability.

[0046] See also Figure 2 In some embodiments, the bottom plate 112 of the housing assembly 100 includes a first guide plate 1121 and a second guide plate 1122. To effectively guide liquid from the mounting area 121 to the drain port 1123, the second guide plate 1122 is tilted relative to the first guide plate 1121. This tilted design allows any liquid that enters the bottom plate 112 to naturally flow downward along the slope until it reaches the drain port 1123 on the first guide plate 1121 and is discharged. This ensures quick and smooth drainage even with large amounts of liquid, reducing the possibility of liquid stagnation within the housing.

[0047] It will be appreciated that in some embodiments, in addition to adopting an inclined design, the second guide plate 1122 and the first guide plate 1121 can also be arranged in a stepped manner, wherein the first guide plate 1121 is positioned lower than the second guide plate 1122. In this arrangement, liquid first accumulates on the higher second guide plate 1122, then gradually flows to the lower first guide plate 1121, and finally drains through the drain port 1123. This stepped structure not only helps improve drainage efficiency but also reduces the risk of liquid directly impacting the first guide plate 1121, thereby extending the service life of the first guide plate 1121 and the entire drainage system. In addition, the stepped layout can also adjust the height difference between each level according to actual needs to accommodate different sizes or types of liquid flow. For example, in the case where a large amount of liquid is expected to enter, the number of steps between the first guide plate 1121 and the second guide plate 1122 can be increased to achieve a smoother transition and further optimize the liquid flow path. At the same time, considering the convenience of maintenance, removable cleaning ports can be added at each step connection to facilitate regular cleaning of sediment or foreign objects, ensuring that the drainage system remains in good working condition for a long time.

[0048] See also Figure 1 In some embodiments, the housing assembly 100 further includes a main beam 130 and a plurality of secondary beams 140, each of which is connected to the base plate 112. The main beams 130 are spaced apart along a first direction X, while the secondary beams 140 are arranged along a second direction Y perpendicular to the first direction X, and each secondary beam 140 is fixed to the main beam 130. The mounting brackets 120 are directly connected to the secondary beams 140, forming a stable support network for supporting heavy-loaded components such as battery modules. This not only effectively disperses the pressure from heavy-loaded components such as battery modules, protecting the base plate 112 from damage, but also provides the necessary rigid support for the mounting brackets 120, ensuring their stable position and non-deformation.

[0049] It will be appreciated that in some embodiments, where greater weight is required or specific size restrictions exist, the main beams 130 and secondary beams 140 can be constructed from materials with higher strength and larger cross-sections. Alternatively, the number of main beams 130 and secondary beams 140 can be appropriately increased to enhance the overall load-bearing capacity of the frame. Furthermore, considering environmental factors, such as earthquake-prone areas or mobile applications, additional reinforcement measures can be implemented for the main beams 130 and secondary beams 140, including but not limited to adding diagonal braces or using elastic materials as connectors, to improve the overall vibration resistance of the housing assembly 100. Furthermore, the connection methods between the main beams 130, secondary beams 140, and base plate 112 include but are not limited to bolting and welding. To facilitate assembly and maintenance, bolting can be used to connect the beams, simplifying the production process and facilitating the subsequent replacement or upgrade of individual components. Furthermore, to ensure good air circulation within the housing body 110 and prevent safety hazards caused by excessive temperatures, sufficient space or ventilation ducts can be reserved between the beams without compromising structural strength.

[0050] See also Figure 4 In some embodiments, the connection positions of the secondary beams 140 and the main beam 130 in the housing assembly 100 are gradually lowered along the second direction Y toward the drain port 1123. Therefore, the bottom plate 112 connected to the secondary beams 140 changes its vertical position as the connection position of each secondary beam 140 relative to the main beam 130 changes. Specifically, the shape of the bottom plate 112 changes to a state that gradually lowers toward the drain port 1123. This design allows liquid to flow along the gradually descending surface of the bottom plate 112, thereby more effectively converging to the drain port 1123. This helps prevent liquid from accumulating on the bottom plate 112, reducing potential damage to internal components such as the battery module caused by accumulated water.

[0051] It will be appreciated that, in some embodiments, to further optimize drainage efficiency, the secondary beam 140 may have a slightly inclined top surface to facilitate rapid liquid flow; alternatively, the secondary beam 140 may utilize a specially treated surface material (including but not limited to a hydrophobic coating) to reduce liquid adhesion and accelerate flow. Furthermore, the secondary beam 140 may be provided with tiny grooves or protrusions to further control liquid flow and ensure even distribution and flow. This not only improves the drainage performance of the entire system but also enhances the stability and durability of the overall structure of the housing assembly 100.

[0052] See also Figure 2In some embodiments, the bottom plate 112 of the housing assembly 100 includes a first guide plate 1121 and a plurality of second guide plates 1122. The second guide plates 1122 are arranged adjacent to each other and alternately arranged with the secondary beams 140. At least one second guide plate 1122 is arranged directly adjacent to the first guide plate 1121. In addition, for ease of description, one of the plurality of secondary beams 140 is defined as a first beam 141, and its connection position with the main beam 130 is lower than the connection position of the other secondary beams 140 with the main beam 130. The first beam 141 connects the first guide plate 1121 and one of the second guide plates 1122. In this way, it is ensured that the liquid can flow smoothly from the higher second guide plate 1122 to the lower first guide plate 1121, and finally be discharged through the drain port 1123.

[0053] It is understood that in some embodiments, in order to further enhance the liquid guiding effect, the second guide plates 1122 are arranged in a stepped manner or connected to each other and arranged at a certain tilt angle, so that the bottom plate 112 has different height differences. As a result, the liquid can gradually descend between each level of the second guide plates 1122, thereby flowing more smoothly. In addition, a sealing strip or other waterproof material is provided at the junction of the guide plate and the secondary beam 140 to enhance the waterproof effect of the shell assembly 100. At the same time, considering the convenience of manufacturing and installation, the second guide plates 1122 and the secondary beam 140 can adopt a modular design to facilitate on-site assembly and later replacement. This modular design also makes maintenance and upgrades more flexible, and partial replacements can be performed according to actual needs without disassembling the entire bottom plate 112 structure. For example, one of the multiple modules is defined as a first module, and each module includes a guide plate and a secondary beam 140 connected to each other. When assembling the base plate 112, the second guide plate 1122 of another module can be connected to the secondary beam 140 of the first module, and the end of the second guide plate 1122 of the first module facing away from the secondary beam 140 located in the first module is connected to the secondary beam 140 of another module, and so on.

[0054] For ease of expression, two adjacent second guide plates 1122 are defined, one of which is the first plate and the other is the second plate. The position where the first plate is connected to the main beam 130 is lower than the position where the second plate is connected to the main beam 130, so that the liquid can flow smoothly from the higher second plate to the lower first plate. The highest point of the secondary beam 140 connected between the first plate and the second plate does not exceed the lowest end of the first plate to ensure that the liquid can flow smoothly without being blocked by the secondary beam 140, further avoiding the possibility of water accumulation on the bottom plate 112, thereby improving the protective effect of the shell assembly 100 on the battery module. Similarly, the highest point of the secondary beam 140 connected between the first guide plate 1121 and the second guide plate 1122 does not exceed the lowest end of the second guide plate 1122. This ensures that the liquid can flow along the predetermined path and avoids water accumulation.

[0055] It is understandable that in some embodiments, in order to further optimize the drainage efficiency, the height difference between the first plate and the second plate can be adjusted to accommodate different drainage needs. For example, when it is expected that there may be a large liquid flow in the accommodating space 111, the height difference or inclination angle between the first plate and the second plate can be appropriately increased to speed up the flow of the liquid. In addition, tiny grooves or guide strips can be provided between the first plate and the second plate to guide the liquid to flow more accurately to the drain port 1123. At the same time, considering the needs of maintenance and cleaning, sufficient space can be reserved at the secondary beam 140 to facilitate regular inspection and cleaning of debris that may block the drainage path. In addition, for application scenarios that require special waterproof performance, sealing strips or other waterproof materials can be added at the junction of the first plate, the second plate and the secondary beam 140 to enhance the overall waterproof effect.

[0056] In some embodiments, an equal number of second deflectors 1122 are arranged on either side of the first deflector 1121 along the second direction Y. This symmetrical design helps maintain the balance of the base plate 112. In particular, it evens out the pressure exerted by the mounting bracket 120 on the base plate 112 or the secondary beam 140, effectively transferring and dissipating stress across the base plate 112. Furthermore, it prevents excessive liquid accumulation on one side of the first deflector 1121, which could affect drainage on the other side. Furthermore, since each secondary beam 140 is lowered one by one at its connection point to the main beam 130, the balanced arrangement of the second deflectors 1122 on both sides of the first deflector 1121 improves the utilization of the main beam 130 in the third direction Z, avoiding excessive dimensions of the main beam 130 in the third direction Z, which could increase costs or even occupy excessive space. This balanced layout allows liquid to flow more efficiently from the second deflectors 1122 to the first deflector 1121, ultimately draining through the drain port 1123. In other words, the drain port 1123 is disposed near the center of the bottom plate 112. In other embodiments, the drain port 1123 can be disposed at any position of the bottom plate 112 while ensuring that the forces at all locations of the bottom plate 112 are balanced.

[0057] It is understood that in some embodiments, if a symmetrical design cannot be achieved due to installation space or other factors, the number of second guide plates 1122 on both sides of the first guide plate 1121 along the second direction Y can differ by one. Even in this case, a reasonable layout can ensure that the liquid can be evenly distributed and flow smoothly, and the total hypotenuse length or total number of steps of the second guide plates 1122 provided on both sides of the first guide plate 1121 is relatively small. Therefore, the dimensional requirements for the main beam 130 along the third direction Z are relatively small, ensuring structural stability while reducing the material cost of the main beam 130. In other embodiments, if an additional second guide plate 1122 is provided on one side of the first guide plate 1121, the flow of the liquid can be balanced by appropriately lowering the height of the secondary beam 140 on that side, or by adding more guide structures on that side.

[0058] See also Figure 2 and Figure 4 In some embodiments, the mounting bracket 120 includes a plurality of support beams 122 arranged along the second direction Y (transverse direction). The support beams 122 have the same dimensions in the third direction Z (a direction perpendicular to the first direction X and the second direction Y) to ensure that the battery modules in each mounting area 121 are stably supported and can withstand consistent pressure distribution. In addition, the same dimensions of the support beams 122 in the third direction Z help reduce the production cost of the support beams 122 (i.e., the structural shapes of the support beams 122 can be the same, so the support beams 122 can be produced using the same mold or process, effectively reducing mold or production line costs). In addition, the same dimensions of the support beams 122 in the third direction Z also avoid situations such as errors in the connection position of the support beam 122 and the corresponding secondary beam 140, which helps reduce the difficulty of assembling the shell assembly 100, thereby improving the assembly efficiency of the shell assembly 100.

[0059] It will be appreciated that in some embodiments, to further enhance the load-bearing capacity and stability of the support beams 122, high-strength materials, including but not limited to aluminum alloys and high-carbon steel, may be used to manufacture the support beams 122. Furthermore, the surface of the support beams 122 may be specially treated, such as with anti-slip grooves or a corrosion-resistant coating, to improve durability and safety. For applications requiring higher precision, fine-tuning mechanisms may be provided on the support beams 122 to allow for subtle adjustments to the battery module position, thereby optimizing the overall layout. Furthermore, to accommodate maintenance and replacement needs, the support beams 122 may be designed as modular components for easy on-site assembly and replacement. Furthermore, to ensure good contact between the battery modules and the support beams 122, cushioning pads or other shock-absorbing materials may be added to the support beams 122 to reduce the impact of vibration and shock on the battery modules. This improves the stability and safety of the system while also enhancing the overall performance of the housing assembly 100. In some embodiments, the dimensions of each support beam 122 in the third direction Z may differ to reduce the design and assembly complexity of the top of the housing assembly 100.

[0060] The second aspect of the present invention further provides an energy storage device, comprising a drainage pipe and a housing assembly 100 according to any of the above-described embodiments or implementations. The drainage pipe is connected to a drainage port 1123 on the first guide plate 1121 of the bottom plate 112 and is used to drain liquid from the interior of the storage space 111. The liquid is first guided to the first guide plate 1121 by the second guide plate 1122, then enters the drainage pipe through the drainage port 1123, and finally exits the housing assembly 100. This effectively prevents liquid from accumulating within the storage space 111, protecting the battery module and other internal components from water damage. An energy storage device employing the housing assembly 100 according to any of the above-described embodiments or implementations can effectively reduce the difficulty of designing and laying out the drainage pipe, reducing obstacles to drainage pipe maintenance or functional expansion, allowing staff to expand the functionality of the drainage pipe at any time. Furthermore, the drainage pipe occupies less space, facilitating staff's thorough inspection or other work in the space surrounding the drainage pipe.

[0061] It is understandable that in some embodiments, in order to further improve the drainage efficiency and reliability, the drainage pipe can adopt a variety of different designs. For example, the drainage pipe can be a pipeline with a certain inclination so that gravity can be used to accelerate the outflow of liquid; or a one-way valve can be set in the drainage pipe to prevent external liquid from flowing back into the shell. In addition, the material of the drainage pipe can be selected from materials with good corrosion resistance, including but not limited to stainless steel, PVC (polyvinyl chloride), etc., to extend the service life. For energy storage equipment that needs to operate for a long time, a filter screen or sedimentation tank can also be added to the drainage pipe to regularly clean impurities that may clog the pipe. At the same time, for ease of maintenance, the drainage pipe can be designed as a detachable part to facilitate cleaning and inspection. In addition, a waterproof cover or protective net can be added to the outlet of the drainage pipe to prevent debris from entering the pipe and causing blockage, so as to improve the reliability and efficiency of the drainage system and enhance the overall performance and life of the energy storage equipment.

[0062] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0063] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or", "and / or" or "and / or" appear in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0064] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
