Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a housing module and an energy storage device. Background Technology

[0002] Energy storage devices typically include an inverter module housed within the device's casing. The inverter module generates a significant amount of heat during operation. To ensure its proper functioning, space is usually reserved around it to increase gas flow within the casing and provide ample wiring space. This improves heat dissipation and facilitates wiring installation. However, constructing this space results in a larger cavity within the energy storage device's casing, making it prone to deformation under load. Utility Model Content

[0003] In view of this, this application provides a housing module and an energy storage device, which can improve the structural strength of the housing module of the energy storage device, making the housing module less prone to deformation.

[0004] In a first aspect, one embodiment of this application provides a housing module applied to an energy storage device, the energy storage device including a battery cell and an inverter module. The housing module includes a mounting shell and a mounting structure. The mounting shell includes a top shell and a bottom shell. The top shell forms an accommodating space, which accommodates at least a portion of the inverter module. The bottom shell accommodates one end of the battery cell. The mounting structure is located within the space formed by the mounting shell. The mounting structure includes a support plate and a shield. The support plate is fixed to the bottom shell and located outside the accommodating space at the end of the battery cell away from the bottom shell. The side of the support plate away from the battery cell is configured to fix the inverter module. The shield is fixed to the support plate and configured to cover the inverter module. The top shell is provided with a first support column and a second support column spaced apart. A portion of the first support column extends out of the accommodating space and is fixed to the support plate. The second support column is located within the accommodating space and abuts against the shield.

[0005] By setting a first support column and a second support column in the top shell, the first support column extends out of the receiving space and is fixed to the support plate, while the support plate is fixed to the bottom shell, so that the top shell and the bottom shell are fixed. The second support column is located in the receiving space and abuts against the shielding cover. When the top shell is subjected to external force, the first support column transmits the force to the bottom shell in time for distribution, and the second support column provides support in the receiving space and disperses the force to the support plate. This ensures that the top shell still has sufficient load-bearing strength even with the receiving space, thereby improving the structural strength of the shell module and improving the problem of the top shell being easily deformed when subjected to external force.

[0006] In at least one embodiment, a plurality of first support columns are provided, the plurality of first support columns are arranged at intervals along the circumference of the top shell, the plurality of first support columns are all arranged near the edge of the top shell, and are all fixed to the support plate.

[0007] By setting multiple first support columns, the external forces on the top shell and / or bottom shell can be further dispersed, thereby reducing stress concentration in the top shell, increasing the structural strength of the shell module, and improving the problem of easy deformation of the top shell and / or bottom shell when subjected to external forces.

[0008] In at least one embodiment, there are multiple second support columns, which are spaced apart inside the accommodating space and all abut against the shielding cover.

[0009] By setting multiple second support columns, the top shell can be supported and the external force on the top shell can be further dispersed, thereby reducing stress concentration on the top shell, increasing the structural strength of the shell module, and thus improving the problem of the top shell being easily deformed when subjected to external forces.

[0010] In at least one embodiment, the shielding cover is provided with stepped holes, and one end of the second support column extends into the stepped holes and abuts against the stepped surface inside the stepped holes.

[0011] By setting stepped holes in the shielding cover, on the one hand, the stepped holes can quickly locate the position of the end of the second support column. Since the second support column is located on the top shell, quickly locating the position between the second support column and the shielding cover can improve the assembly efficiency of the top shell and the shielding cover. On the other hand, the stepped holes can limit the position of the second support column to reduce the shaking of the second support column and improve the stability of the contact between the second support column and the shielding cover.

[0012] In at least one embodiment, the mounting structure further includes a third support column located on the side of the support plate away from the battery cell and connecting the shield and the support plate.

[0013] By setting a third support column, the third support column can serve to support the shielding cover. When the mounting shell is subjected to external force, the external force can be transmitted through the first, second and third support columns, thereby further improving the problem of the top shell being prone to deformation when subjected to external force.

[0014] In at least one embodiment, the edge of the support plate is provided with a flange facing the side where the battery cell is located. The flange is connected to the bottom shell, and the support plate, the flange, and the bottom shell together form an installation space for accommodating the battery cell.

[0015] By setting a flange, it is easy to fix the support plate and the bottom shell. At the same time, the installation space formed by the support plate, flange and bottom shell limits the position of the battery cell. When the installation shell is subjected to external force impact, it can reduce the shaking of the battery cell and improve the installation stability of the battery cell.

[0016] In at least one embodiment, the bottom shell is provided with a connecting post, which is fixedly connected to the flange.

[0017] By setting connecting posts in the bottom shell, the connecting posts can position the battery cell before connecting the support plate and the bottom shell, so that the battery cell can be quickly installed into the bottom shell, thereby improving the assembly efficiency of the battery cell.

[0018] In at least one embodiment, the first support column and the top shell are integrally formed.

[0019] By making the first support column and the top shell a single molded structure, the structural strength of the first support column and the top shell can be improved without physical interruption.

[0020] In at least one embodiment, the second support column and the top shell are integrally formed.

[0021] By making the second support column and the top shell a single molded structure without any physical interruption, the structural strength of the second support column and the top shell can be improved.

[0022] In at least one embodiment, the mounting housing further includes a panel housing, which is disposed between the top housing and the bottom housing and connects the top housing and the bottom housing. The panel housing, the top housing and the bottom housing enclose a space for accommodating the mounting structure, and the support plate is fixedly connected to the panel housing.

[0023] When the panel shell of the mounting shell is subjected to an external impact, the external force on the panel shell can be transmitted to the support plate, top shell and bottom shell, thereby dispersing the external force on the panel shell, further improving the structural strength of the shell module and improving the problem of easy deformation of the panel shell when subjected to external force.

[0024] Secondly, embodiments of this application provide an energy storage device, including a battery cell, an inverter module, and the aforementioned housing module. The battery cell is installed inside the mounting shell of the housing module; the inverter module is disposed inside the mounting shell and installed on the mounting structure of the housing module, and the inverter module is electrically connected to the battery cell.

[0025] The aforementioned energy storage device employs the aforementioned shell module. By installing a first support column and a second support column on the top shell, the first support column extends out of the receiving space and is fixed to the support plate, while the support plate is fixed to the bottom shell, thus securing the top and bottom shells. The second support column is located within the receiving space and abuts against the shielding cover. When the top shell bears external forces, the first support column promptly transmits the force to the bottom shell for distribution, while the second support column provides support within the receiving space and disperses the force to the support plate. This ensures that the top shell, despite having a receiving space, still possesses sufficient load-bearing strength, thereby enhancing the structural strength of the shell module and mitigating the problem of the top shell easily deforming under external forces.

[0043] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0044] 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. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0045] Energy storage devices typically include an inverter module housed within the device's casing. The inverter module generates a significant amount of heat during operation. To ensure its proper functioning, space is usually reserved around it to increase gas flow within the casing and provide ample wiring space. This improves heat dissipation and facilitates wiring installation. However, constructing this space results in a larger cavity within the energy storage device's casing, making it prone to deformation under load.

[0046] This application provides a housing module applied to an energy storage device, which includes a battery cell and an inverter module. The housing module includes a mounting shell and a mounting structure. The mounting shell includes a top shell and a bottom shell. The top shell forms an accommodating space that accommodates at least a portion of the inverter module. The bottom shell accommodates one end of the battery cell. The mounting structure is located within the space formed by the mounting shell and includes a support plate and a shield. The support plate is fixed to the bottom shell and located outside the accommodating space at the end of the battery cell away from the bottom shell. The side of the support plate away from the battery cell is configured to fix the inverter module. The shield is fixed to the support plate and configured to cover the inverter module. A first support column and a second support column are provided between the top shells. A portion of the first support column extends out of the accommodating space and is fixed to the support plate. The second support column is located within the accommodating space and abuts against the shield.

[0047] By setting a first support column and a second support column in the top shell, the first support column extends out of the receiving space and is fixed to the support plate, while the support plate is fixed to the bottom shell, so that the top shell and the bottom shell are fixed. The second support column is located in the receiving space and abuts against the shielding cover. When the top shell is subjected to external force, the first support column transmits the force to the bottom shell in time for distribution, and the second support column provides support in the receiving space and disperses the force to the support plate. This ensures that the top shell still has sufficient load-bearing strength even with the receiving space, thereby improving the structural strength of the shell module and improving the problem of the top shell being easily deformed when subjected to external force.

[0048] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0049] Please see Figure 1 and Figure 2 The embodiments of this application provide a housing module 100 and an energy storage device 200. The energy storage device 200 has the functions of storing and discharging electricity for use as backup power for homes, production units, outdoor work, and outdoor recreation.

[0050] Please see Figure 1 and Figure 2 In some embodiments, the housing module 100 is applied to the energy storage device 200. It is understood that the energy storage device 200 includes the housing module 100 and the battery cell 201. The battery cell 201 is installed in the housing module 100 so as to realize the functions of energy storage and discharge of the energy storage device 200 through the battery cell 201, while the housing module 100 provides protection for the battery cell 201.

[0051] Please see Figure 1 and Figure 2In some embodiments, the energy storage device 200 includes an inverter module 202. The inverter module 202 is disposed within the housing module 100 and is electrically connected to the battery cell 201. The inverter module 202 is used to control the AC / DC conversion of the output current of the battery cell 201. The energy storage device 200 equipped with the inverter module 202 can be a small portable power bank, a residential energy storage power supply, an industrial or commercial energy storage power supply, or a containerized energy storage power supply, etc.

[0052] In some embodiments, the inverter module 202 may be omitted. An energy storage device 200 without an inverter module 202 can be used independently. An energy storage device 200 without an inverter module 202 typically only outputs DC power. When used independently, an energy storage device 200 without an inverter module 202 can be used in conjunction with an energy storage device 200 with an inverter module 202 as a power system providing additional battery capacity.

[0053] Please see Figure 2 and Figure 3 In some embodiments, the housing module 100 includes a mounting shell 10, which includes a top shell 11 and a bottom shell 12. The top shell 11 forms a receiving space 110 that accommodates at least a portion of the inverter module 202, and the bottom shell 12 accommodates one end of the battery cell 201.

[0054] By configuring the mounting housing 10 into a structure including a top housing 11 and a bottom housing 12, the battery cell 201 can be installed on the bottom housing 12 first, and then the top housing 11 can be assembled, so as to facilitate the overall assembly of the energy storage device 200.

[0055] Please see Figure 2 and Figure 3 In some embodiments, the housing module 100 includes a mounting structure 20 located within the space formed by the housing 10. The mounting structure 20 includes a support plate 21 and a shielding cover 22. The support plate 21 is fixed to the bottom shell 12 and located outside the receiving space 110, at the end of the battery cell 201 away from the bottom shell 12. The side of the support plate 21 away from the battery cell 201 is configured to fix the inverter module 202. The shielding cover 22 fixes the support plate 21 and is configured to cover the inverter module 202 to provide electromagnetic shielding for the inverter module 202.

[0056] In some embodiments, the support plate 21 is a sheet metal part, which can cooperate with the shielding cover 22 to electromagnetically shield the inverter module 202 and improve the electromagnetic shielding effect.

[0057] Please see Figure 3 and Figure 6In some embodiments, the top shell 11 is provided with a first support column 111 and a second support column 112 at intervals. The first support column 111 extends out of the receiving space 110 and is fixed to the support plate 21. The second support column 112 is located in the receiving space 110 and abuts against the shielding cover 22.

[0058] Since the first support column 111 and the second support column 112 are located on the top shell 11, when the top shell 11 is subjected to external force, the first support column 111 and the second support column 112 can support the top shell 11. Since the shielding cover 22 is fixed to the support plate 21, and the support plate 21 is fixed to the bottom shell 12, the external force on the top shell 11 can be dispersed to the support plate 21 through the first support column 111, and the external force on the top shell 11 can be dispersed to the shielding cover 22, the support plate 21 and the bottom shell 12 through the second support column 112. This allows the top shell 11 to still have sufficient load-bearing strength even with the accommodating space 110 provided, thereby improving the structural strength of the shell module 100 and improving the problem of the top shell 11 being prone to deformation when subjected to external force.

[0059] Understandably, when the top shell 11 is subjected to an external impact, since the shielding cover 22 is fixed to the support plate 21, and the support plate 21 is fixed to the bottom shell 12, the external force on the top shell 11 can be distributed sequentially to the support plate 21 and the bottom shell 12 through the first support column 111. The external force on the top shell 11 can be distributed sequentially to the shielding cover 22, the support plate 21, and the bottom shell 12 through the second support column 112.

[0060] Please see Figure 3 , Figure 4 and Figure 8 In some embodiments, the support plate 21 is provided with mounting posts 212, and the mounting posts 212 and the first support post 111 are fixedly connected by a first fastener 101. By providing the mounting posts 212, the support plate 21 is connected to the first support post 111 through the mounting posts 212. The mounting posts 212 can distribute the fastening force of the first fastener 101 to a wider area, reduce local stress concentration, and improve the situation of deformation or cracking caused by the direct connection between the support plate 21 and the first fastener 101.

[0061] For example, the first fastener 101 can be a bolt or screw to facilitate the assembly and disassembly of the support plate 21 and the first support column 111. Since the first support column 111 is located on the top shell 11, it facilitates the assembly and disassembly of the top shell 11 and the support plate 21, thereby facilitating the inspection and maintenance of the internal components of the housing module 100.

[0062] Please see Figure 3 and Figure 4In some embodiments, the first support column 111 is a hollow column with a connecting channel 1110. The top shell 11 is provided with an opening 1111 that communicates with the connecting channel 1110, so that the first fastener 101 can pass through the opening 1111 from the outside of the top shell 11, thereby facilitating the connection of the first fastener 101 with the support plate 21 and the first support column 111 and improving the assembly efficiency of the first support column 111 and the support plate 21. Furthermore, setting the first support column 111 as a hollow column can also reduce the weight of the housing module 100.

[0063] Please see Figure 3 , Figure 6 and Figure 8 In some embodiments, multiple first support columns 111 are provided, and the multiple first support columns 111 are arranged at intervals along the circumference of the top shell 11. The multiple first support columns 111 are all arranged close to the edge of the top shell 11 and are all fixed to the support plate 21.

[0064] By setting multiple first support columns 111, the external forces on the top shell 11 can be further dispersed, thereby reducing stress concentration on the top shell 11, increasing the structural strength of the shell module 100, and improving the problem that the top shell 11 and / or bottom shell 12 are prone to deformation when subjected to external forces.

[0065] Please see Figure 3 , Figure 6 and Figure 8 In some embodiments, there are multiple second support columns 112, which are spaced apart inside the accommodating space 110 and all abut against the shielding cover 22.

[0066] By setting multiple second support columns 112, the multiple second support columns 112 support the top shell and further disperse the external force on the top shell 11, thereby reducing the stress concentration of the top shell 11 and / or the bottom shell 12, increasing the structural strength of the shell module 100, and thus improving the problem that the top shell 11 is prone to deformation when subjected to external forces.

[0067] Please see Figure 6 In some embodiments, the top shell 11 has a shell sidewall 113, and the distance between the first support column 111 and the shell sidewall 113 is less than the distance between the second support column 112 and the shell sidewall 113, so that the first support column 111 is disposed close to the edge of the top shell 11, and the second support column 112 is disposed inside the accommodating space 110.

[0068] For example, a plurality of first support columns 111 are provided on the shell sidewall 113 so that the plurality of first support columns 111 are located at the edge of the top shell 11, thereby reducing the volume occupied by the first support columns 111 in the accommodating space 110; wherein, the plurality of first support columns 111 are arranged at intervals around the shield 22 so that the assembly position of the top shell 11 can be quickly positioned through the cooperation of the plurality of first support columns 111 and the shield 22, thereby improving the assembly efficiency of the top shell 11 and the support plate 21.

[0069] Please see Figure 3 , Figure 6 and Figure 8 In some embodiments, multiple second support columns 112 are disposed inside multiple first support columns 111, that is, multiple second support columns 112 are located on the side of multiple first support columns 111 close to the accommodating space 110; the projection of each second support column 112 along a third direction completely falls into the side of the shielding cover 22 facing the top shell 11, so as to ensure that there is sufficient abutment area between each second support column 112 and the shielding cover 22, thereby improving the abutment effect between the multiple second support columns 112 and the shielding cover 22; wherein the third direction is the distribution direction of the top shell 11 and the bottom shell 12.

[0070] In some embodiments, the second support column 112 is a hollow column, and the structure of the second support column 112 is similar to that of the first support column 111. By setting the second support column 112 as a hollow column, the weight of the housing module 100 can be reduced.

[0071] Please see Figure 8 , Figure 9 and Figure 10 In some embodiments, the shield 22 is provided with a stepped hole 220, and one end of the second support column 112 extends into the stepped hole 220 and abuts against the step surface 221 inside the stepped hole 220.

[0072] By providing a stepped hole 220 in the shielding cover 22, on the one hand, the stepped hole 220 can quickly position the end of the second support column 112. Since the second support column 112 is located on the top shell 11, quickly positioning the position between the second support column 112 and the shielding cover 22 can improve the assembly efficiency of the top shell 11 and the shielding cover 22. On the other hand, the stepped hole 220 can limit the position of the second support column 112 to reduce the shaking of the second support column 112 and improve the stability of the contact between the second support column 112 and the shielding cover 22.

[0073] Please see Figure 2 , Figure 3 and Figure 11 In some embodiments, the mounting structure 20 further includes a third support column 23, which is located on the side of the support plate 21 away from the battery cell 201 and connects the shield 22 and the support plate 21.

[0074] The third support column 23 can support the shield 22, so that when the mounting shell 10 is subjected to external force, the external force can be transmitted through the first support column 111, the second support column 112 and the third support column 23, thereby further improving the problem that the top shell 11 is prone to deformation when subjected to external force.

[0075] Please see Figure 11 In some embodiments, the two ends of the third support column 23 are connected to the shield 22 and the support plate 21 respectively by the second fastener 102.

[0076] For example, the second fastener 102 may be a bolt or screw, so as to enable the assembly and disassembly of the shield 22, the support plate 21 and the third support column 23, so as to facilitate the replacement of the third support column 23 when the third support column 23 is severely deformed.

[0077] Please see Figure 2 , Figure 3 and Figure 8 In some embodiments, the edge of the support plate 21 is provided with a flange 210, which faces the side where the battery cell 201 is located. The flange 210 is connected to the bottom shell 12. The support plate 21, the flange 210 and the bottom shell 12 enclose and form an installation space 2101 for accommodating the battery cell 201.

[0078] By setting the flange 210, it is convenient to fix the support plate 21 and the bottom shell 12. At the same time, the installation space 2101 formed by the support plate 21, the flange 210 and the bottom shell 12 limits the position of the battery cell 201. When the installation shell 10 is subjected to external force impact, the shaking of the battery cell 201 can be reduced, and the installation stability of the battery cell 201 can be improved.

[0079] Please see Figure 2 , Figure 3 and Figure 9 For example, the support plate 21 includes a first plate segment 211, which is fixedly connected to the third support column 23. The first plate segment 211 is used to support and install the inverter module 202, and the shield 22 is connected to the first plate segment 211.

[0080] The support plate 21 has flanges 210 on both sides along the first direction, which extend toward and connect to the bottom shell 12. The first plate segment 211, the flanges 210, and the bottom shell 12 together form an installation space 2101, in which the battery cell 201 is housed, that is, the support plate 21 covers the battery cell 201. The first direction is perpendicular to the third direction.

[0081] In some embodiments, the first plate segment 211 and the flange 210 are integrally formed, and the integrally formed structure has no physical interruption, which can make the connection strength between the first plate segment 211 and the flange 210 better. In other embodiments, the flange 210 may also be welded to the first plate end 211 or threaded onto the first plate segment 211. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0082] Please see Figure 8 and Figure 9 In some embodiments, multiple flanges 210 are provided, and multiple flanges 210 are connected to both sides of the first plate segment 211 along the first direction. The multiple flanges 210 on each side of the first plate segment 211 are spaced apart along the second direction.

[0083] Compared to directly setting the flange 210 as a large plate, setting multiple flanges 210 can ensure the structural strength of the support plate 21 while reducing its weight. The first, second, and third directions are perpendicular to each other.

[0084] Please see Figure 2 , Figure 7 and Figure 8 In some embodiments, the bottom shell 12 is provided with a connecting post 120, which is fixedly connected to the flange 210. By providing the connecting post 120 on the bottom shell 12, the connecting post 120 can position the battery cell 201 before connecting the support plate 21 and the bottom shell 12, so that the battery cell 201 can be quickly installed onto the bottom shell 12, thereby improving the assembly efficiency of the battery cell 201.

[0085] Please see Figure 2 , Figure 7 and Figure 8 In some embodiments, multiple connecting posts 120 are provided, and multiple sets of connecting groups 121 are distributed along the first direction. The multiple connecting posts 120 of each connecting group 121 are spaced apart along the second direction, and at least some of the multiple connecting posts 120 of the connecting groups 121 are staggered along the first direction. Each flange 210 corresponds to a connecting post 120.

[0086] Please see Figure 2 , Figure 7 and Figure 11 In some embodiments, the flange 210 and the connecting post 120 are connected by a third fastener 103. For example, the third fastener 103 may be a screw or bolt, so as to enable the disassembly and assembly of the shield 22 and the bottom shell 12, so as to facilitate the installation of the battery cell 201. The connecting post 120 can distribute the fastening force of the third fastener 103 to a wider area, reduce local stress concentration, and improve the situation of deformation or cracking caused by the direct connection of the bottom shell 12 to the third fastener 103.

[0087] In some embodiments, the connecting column 120 and the bottom shell 12 are integrally formed, and the integrally formed structure has no physical interruption, which can improve the structural strength of the connecting column 120 and the bottom shell 12.

[0088] In some embodiments, the first support column 111 and the top shell 11 are integrally formed structures. The integrally formed structure has no physical interruption, which can improve the structural strength of the first support column 111 and the top shell 11.

[0089] In some embodiments, the second support column 112 and the top shell 11 are integrally formed. The integrally formed structure has no physical interruption, which can improve the structural strength of the second support column 112 and the top shell 11.

[0090] Please see Figure 1 and Figure 2 In some embodiments, the mounting shell 10 further includes a panel shell 13, which is disposed between the top shell 11 and the bottom shell 12 and connects the top shell 11 and the bottom shell 12. The panel shell 13, the top shell 11 and the bottom shell 12 enclose a space to accommodate the mounting structure 20. The support plate 21 is fixedly connected to the panel shell 13 so that when the panel shell 13 of the mounting shell 10 is subjected to an external force impact, the external force on the panel shell 13 can be transmitted to the support plate 21, the top shell 11 and the bottom shell 12, thereby dispersing the external force on the panel shell 13, further improving the structural strength of the shell module 100 and improving the problem that the panel shell 13 is easily deformed when subjected to external force.

[0091] Please see Figure 1 and Figure 2 In some embodiments, the panel housing 13 includes a front housing 131 and a rear housing 132, which are distributed along a second direction. The support plate 21 is fixedly connected to the front housing 131 and / or the rear housing 132 to improve the overall structural strength of the housing module 100.

[0092] Please see Figure 1 and Figure 2 In some embodiments, the panel shell 13 further includes two side panels 133, which are distributed along a first direction. Each side panel 133 covers the shell sidewall 113 of the top shell 11. The support plate 21 is fixedly connected to at least one side panel 133 to improve the overall structural strength of the shell module 100.

[0093] Please see Figure 2 , Figure 3 and Figure 5In some embodiments, the support plate 21 includes a connecting segment 213, which is connected to the first plate segment 211 and protrudes toward the bottom shell 12. The panel shell 13 is provided with a fixing part 134. The connecting segment 213 and the fixing part 134 are stacked and fixedly connected by a fourth fastener 104. Exemplarily, the fourth fastener 104 may be a screw or a bolt, so as to enable the panel shell 13 and the support plate 21 to be disassembled and assembled, so as to facilitate the inspection and maintenance of the components inside the mounting shell 10.
