Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and more specifically, to a battery rack and an energy storage device. Background Art

[0002] At present, after the battery rack of the energy storage device is painted, the surface friction coefficient is relatively large. When assembling a large-capacity battery inward, due to the large weight of the battery itself, the generated frictional force is also relatively large, increasing the difficulty of pushing in or pulling out the battery pack and resulting in low assembly efficiency. Summary of the Utility Model

[0003] The utility model aims to at least solve the technical problem of low assembly efficiency when pushing in or pulling out the battery pack in the prior art or related technologies.

[0004] In view of this, an embodiment of the first aspect of the utility model provides a battery rack.

[0005] An embodiment of the second aspect of the utility model provides an energy storage device.

[0006] To achieve the above object, an embodiment of the utility model provides a battery rack, including: a plurality of racks arranged oppositely, each rack including: a plurality of support columns and a plurality of support frames detachably connected, the support columns extending along a first direction, the support frames extending along a second direction, the support frames including a bearing surface for contacting and supporting the energy storage battery; a partition plate arranged on the bearing surface; wherein, the friction coefficient of the surface of the partition plate away from the bearing surface is lower than that of the bearing surface.

[0007] The battery rack proposed according to the present utility model significantly reduces friction, improves safety and stability, and is convenient for assembly and maintenance. Among them, the battery rack includes a plurality of oppositely arranged rack bodies, and each rack body includes support columns and support frames arranged alternately. Specifically, the support columns extend in a first direction, and the support frames extend in a second direction. The first direction and the second direction are not the same direction. The support columns, as the main load-bearing structure of the battery rack, extend in the first direction. Through the arrangement of a plurality of support columns, the weight of the energy storage battery can be dispersed, the pressure on a single support point can be reduced, and the load-bearing capacity of the battery rack can be enhanced. The support frames extend in the second direction to form a support platform for the battery, and the bearing surface is used to contact and support the energy storage battery. It can be understood that the bearing surface usually has a relatively high coefficient of friction to prevent the battery from sliding during transportation or movement when it is in direct contact with the bearing surface, ensuring the safe fixation of the battery. On this basis, partitions are provided on the bearing surface. By restricting the coefficient of friction of the surface on one side of the partition away from the bearing surface to be lower than that of the bearing surface, the friction when the battery is pushed in or pulled out can be reduced, and the operation difficulty can be reduced. In addition, under the action of the partitions, it can also help disperse the weight of the battery, reduce local pressure, and at the same time provide additional support points to enhance the stability of the battery pack.

[0008] It should be added that the support columns and the support frames are detachably connected, which can improve the flexibility of the assembly and disassembly of the battery rack, facilitate transportation, maintenance and replacement of components. At the same time, users can adjust the configuration of the support columns and the support frames according to specific needs to adapt to different types and sizes of energy storage batteries.

[0009] It should be added that the support columns are arranged alternately with the support frames in the first direction and the second direction to form a stable support structure, which can improve the overall stability of the battery rack and avoid deformation or inclination caused by uneven stress.

[0010] In some technical solutions, optionally, the shape of the partition is adapted to the shape of the support frame; or, the shape of the partition is adapted to the shape of the bearing surface.

[0011] In this technical solution, the shape of the partition can be selectively adapted to the shape of the support frame or the bearing surface. The partition can better cover and contact the bearing surface on the support frame, and ensure a tight fit between the partition and the support frame or the bearing surface, which helps to resist sliding that may occur during vibration or movement and increases the overall stability of the structure. At the same time, using a partition with a shape-adapted design can be installed on the support frame or the bearing surface more quickly and accurately, simplifies the assembly process, improves production efficiency, and reduces the possibility of assembly errors.

[0012] It can be understood that the shape of the partition can be adapted to the overall shape of the support frame. During installation, the partition is equivalent to cooperating with the entire support frame. Alternatively, the shape of the partition is adapted to the shape of a part of the support frame, that is, the bearing surface. In this case, during installation, the partition only needs to cooperate with the bearing surface to achieve assembly.

[0013] In some technical solutions, optionally, the support frame specifically includes a connecting wall and a bearing wall connected to each other. An angle is formed between the connecting wall and the bearing wall. A first fitting hole is provided on the connecting wall, and one side of the bearing wall is a bearing surface.

[0014] In this technical solution, the structure of the support frame is further refined to include a connecting wall and a bearing wall. Among them, the connecting wall is responsible for connecting the support frame to the support column or other structural components. The connecting wall realizes a firm connection with other components through the first fitting hole provided on it.

[0015] The bearing wall is connected to the connecting wall, and an angle is formed between the two. One side of the bearing wall is the bearing surface, which is directly used to contact and support the energy storage battery. The bearing wall improves the load-bearing capacity of the support frame through the angle with the connecting wall. Under the action of the angle, the weight of the energy storage battery can be transmitted from the support frame to other structures connected to it, such as the support column, thereby improving the load-bearing capacity and stability of the battery rack.

[0016] It can be understood that since an angle is designed between the connecting wall and the bearing wall, the support frame can better bear the load in the vertical direction and transfer part of the load to the lateral support. This can reduce the situation of single-point stress on the bearing surface and avoid deformation or damage caused by excessive concentrated stress.

[0017] Among them, a first fitting hole is provided on the connecting wall for connecting with the support column or other structural components through bolts, screws or other fasteners.

[0018] Among them, the existence of the first fitting hole ensures the modular installation and flexible assembly of the support frame. This design allows the support frame to closely cooperate with other components while retaining a certain degree of assembly flexibility, facilitating the adjustment of the position or quantity of the support frame according to actual needs. In addition, the standardized design of the fitting hole helps to improve the installation accuracy and the overall structural stability.

[0019] It can be understood that the support frame is fixedly connected to the support column through the first fitting hole on its connecting wall, forming a stable structural framework. The support column extends in the first direction, while the support frame extends in the second direction through the connecting wall, forming a complementary support system between the two.

[0020] The included angle design between the connecting wall and the bearing wall ensures that the support frame can effectively bear the weight of the battery. The bearing surface of the bearing wall provides support in the horizontal position, while the connecting wall fixes the support frame on the support column through the first mating hole, forming an integral framework.

[0021] In some technical solutions, optionally, it further includes: a limiting protrusion provided at one end of the connecting wall away from the bearing wall; wherein, the limiting protrusion extends from the connecting wall in a direction parallel to the bearing wall.

[0022] In this technical solution, by providing a limiting protrusion at one end of the connecting wall away from the bearing wall, the position of the energy storage battery on the support frame can be effectively limited, preventing the battery from undergoing excessive displacement or falling off during use. It can be understood that the limiting protrusion extends horizontally from the connecting wall, that is, in a direction parallel to the bearing wall. When the energy storage battery is assembled, the limiting protrusion can contact the upper and lower edges of the energy storage battery during battery installation, realizing the limitation of the battery position.

[0023] In some technical solutions, optionally, it further includes: a tail-end baffle provided at one end of the support frame along the second direction, and the tail-end baffle is connected to the connecting wall and the bearing wall.

[0024] In this technical solution, by providing a tail-end baffle and arranging the tail-end baffle at one end of the support frame in the second direction, it can play a role in blocking and limiting the energy storage battery placed on the support frame, preventing the battery from slipping off the end of the support frame. It can be understood that when the energy storage battery is inserted into the battery rack, the tail end of the energy storage battery will contact the tail-end baffle, preventing it from moving further, realizing anti-detachment and reducing the safety risk.

[0025] Wherein, the tail-end baffle is connected to the connecting wall and the bearing wall of the support frame, forming a stable integral structure, and this connection can be welding, bolt connection or other reliable connection methods.

[0026] The tail-end baffle is arranged at one end of the support frame along the second direction, and specifically can be perpendicular to the bearing surface, so that the tail-end baffle can effectively block the battery from slipping off the end of the support frame, and at the same time does not affect the normal placement and use of the battery on the bearing surface.

[0027] In some technical solutions, optionally, it further includes: a guide plate provided at the other end of the support frame along the second direction, the guide plate is connected to the connecting wall, and the guide plate extends toward the side away from the bearing wall.

[0028] In this technical solution, the guide plate is arranged at the inlet end of the support frame, that is, the guide plate and the tail baffle are respectively arranged at both ends of the support frame in the second direction, and the energy storage battery is assembled and installed from the side of the guide plate. When installing the energy storage battery, the guide plate can contact the battery first during battery installation, guiding the battery to enter the support frame along the correct direction, and at the same time not affecting the placement of the battery on the bearing surface. The guide plate can play a role in guiding the battery to smoothly enter the support frame, making the battery installation process smoother.

[0029] It can be understood that the existence of the guide plate can prevent the battery from directly contacting the edge of the support frame during the installation process, thereby reducing friction and possible collision damage. At the same time, the battery can be installed on the support frame more quickly and accurately during installation, saving installation time and improving work efficiency.

[0030] Among them, the guide plate is connected to the connecting wall, ensuring the stable installation of the guide plate. The specific connection method can be selected according to the actual situation, such as welding, bolt connection, etc.

[0031] In some technical solutions, optionally, it further includes: an assembly hole, which is arranged on the bearing wall, and the second dimension of the assembly hole in the second direction is greater than the first dimension of the assembly hole in the first direction.

[0032] In this technical solution, by arranging the assembly hole on the bearing wall, it can be used to install and fix the energy storage battery or related components. Among them, the dimension of the assembly hole in the second direction is greater than that in the first direction, enabling it to adapt to processing tolerances and assembly errors to a certain extent, and at the same time providing convenience for subsequent adjustment and maintenance.

[0033] The larger second dimension enables the energy storage battery to have a greater movement space in the second direction during the assembly process, facilitating position adjustment and alignment, thereby improving the efficiency and accuracy of assembly.

[0034] Among them, the assembly hole is arranged on the bearing wall and can be connected to related components through bolts, rivets or other connecting pieces.

[0035] Among them, the assembly hole can be a rectangular hole or a waist-shaped hole.

[0036] In some technical solutions, optionally, the support frame is provided with a first mating hole, and the support column is provided with a second mating hole. The detachable connection between the support column and the support frame is realized through the cooperation of the connecting piece with the first mating hole and the second mating hole.

[0037] In this technical solution, the detachable connection between the support column and the support frame is realized through the cooperation of the first mating hole, the second mating hole and the connecting piece, thereby realizing the stable connection between the support column and the support frame and ensuring the overall structural stability of the battery rack.

[0038] Specifically, the first mating hole is provided on the connecting wall of the support frame, and the second mating hole is provided on the support column. Their positions correspond to each other to ensure that the connecting member can accurately pass through and achieve the connection function. During the actual installation process, it is necessary to align the positions of the support column and the support frame, align the first mating hole and the second mating hole, and then insert the connecting member for fixation.

[0039] It can be understood that when a certain component is damaged or needs to be replaced, it can be conveniently disassembled for repair or replacement without the need to replace the entire battery rack, reducing the maintenance cost.

[0040] During transportation and storage, the support column and the support frame can be disassembled into smaller components, saving space and facilitating handling and management.

[0041] Among them, the connecting member passes through the second mating hole on the support column and the first mating hole on the support frame, tightly connecting the two together. The connecting member can be a bolt, a screw, etc.

[0042] In some technical solutions, optionally, it further includes: a paint layer provided on the surface of the support frame; an adhesive provided on the paint layer of the bearing surface; wherein, the thickness of the paint layer is not less than 100 microns, and the thickness of the adhesive is not greater than 0.3 mm.

[0043] In this technical solution, a paint layer and an adhesive are provided on the surface of the support frame. Among them, the paint layer is provided on the surface of the support frame, which can prevent the support frame from being corroded and oxidized, and extend the service life of the battery rack. In addition, by providing the adhesive on the paint layer of the bearing surface, it is convenient to achieve the adhesion with the separator.

[0044] Among them, the thickness of the paint layer is greater than or equal to 100 microns to ensure the anti-corrosion effect. In addition, by connecting through an adhesive layer between the paint layer and the separator, the surface of the support frame can be prevented from directly contacting the energy storage battery, avoiding the energy storage battery from damaging the paint layer.

[0045] Among them, the paint layer is directly coated on the surface of the support frame to form a protective film. The thickness of the adhesive is not greater than 0.3 mm, which can provide sufficient adhesive force and will not increase too much thickness, ensuring that the separator can be stably fixed on the bearing surface and will not fall off or shift during use.

[0046] The paint layer covers the entire surface of the support frame, including the connecting wall and the bearing wall. The adhesive is located on the paint layer of the bearing surface and has a large contact area with the separator to provide sufficient connection ability.

[0047] An embodiment of the second aspect of the present application provides an energy storage device, including: a battery rack; an energy storage battery provided between multiple frames of the battery rack.

[0048] The energy storage device provided by the present application includes a battery rack and batteries. The battery rack provides a stable support structure for the energy storage batteries, ensuring that the energy storage batteries can be safely placed therein and preventing the batteries from shaking, displacing, or toppling during use.

[0049] The design of multiple racks enables the energy storage batteries to be arranged orderly in the battery rack, facilitating the management and maintenance of the batteries and also conducive to improving the space utilization rate.

[0050] The energy storage batteries are located inside the battery rack. The support frames and partitions of each rack work together to fix the energy storage batteries in specific positions, keeping a certain distance between the batteries, which is beneficial for heat dissipation and maintenance.

[0051] Since the energy storage device includes any of the above battery racks, it has the beneficial effects of any of the above battery racks, which will not be elaborated here.

[0052] Furthermore, the size of the battery rack in the second direction is larger than the size of the energy storage battery in the second direction; wherein, in the second direction, the difference between the size of the energy storage battery and the size of the battery rack is 2 mm to 4 mm.

[0053] In the second direction, the size of the battery rack is larger than the size of the energy storage battery, and the difference between the two is 2 mm to 4 mm. The size of the battery rack is slightly larger than the size of the energy storage battery, providing a certain margin for the installation of the energy storage battery. This can ensure that the energy storage battery can be smoothly installed into the battery rack and also facilitate the replacement and maintenance of the battery.

[0054] Those skilled in the art should understand that considering the tolerances in the manufacturing and assembly processes and the possible thermal expansion and deformation of the batteries, leaving an appropriate size difference can avoid problems such as difficult installation or battery damage due to pressure caused by size mismatch.

[0055] The additional aspects and advantages of the present utility model will become apparent in the following description section or be learned through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the embodiments of the present utility model, the embodiments of the present utility model will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0070] In the following description, many specific details are set forth in order to fully understand the present application. However, the embodiments of the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited to the limitations of the specific embodiments disclosed below.

[0071] The following will refer to Figures 1 to 10 Describe some embodiments according to the present utility model.

[0072] As Figure 1 and Figure 2 shown, this embodiment provides a battery rack 100, which significantly reduces friction, improves safety and stability, and is convenient for assembly and maintenance. Among them, the battery rack 100 includes a plurality of rack bodies 102 arranged oppositely, and each rack body 102 includes support columns 1022 and support frames 1032 arranged alternately. Specifically, the support columns 1022 extend along a first direction, and the support frames 1032 extend along a second direction. The first direction and the second direction are not the same direction. The support columns 1022 serve as the main load-bearing structure of the battery rack 100 and extend along the first direction. By arranging a plurality of support columns 1022, the weight of the energy storage battery 202 can be dispersed, the pressure on a single support point can be reduced, and the load-bearing capacity of the battery rack 100 can be enhanced. The support frames 1032 extend along the second direction to form a support platform for the battery, and the bearing surface 1038 is used to contact and support the energy storage battery 202. It can be understood that the bearing surface 1038 usually has a relatively high coefficient of friction to prevent the battery from sliding during transportation or movement when it is in direct contact with the bearing surface 1038, ensuring the safe fixation of the battery. On this basis, a partition 104 is provided on the bearing surface 1038. By restricting the coefficient of friction of the surface of the partition 104 away from the bearing surface 1038 to be lower than that of the bearing surface 1038, the friction when the battery is pushed in or pulled out can be reduced, and the operation difficulty can be reduced. In addition, under the action of the partition 104, it can also help to disperse the weight of the battery, reduce the local pressure, and at the same time provide additional support points to enhance the stability of the battery pack.

[0073] It should be added that the support columns 1022 and the support frames 1032 are detachably connected, which can improve the flexibility of the assembly and disassembly of the battery rack 100, and is convenient for transportation, maintenance and replacement of components. At the same time, users can adjust the configuration of the support columns 1022 and the support frames 1032 according to specific needs to adapt to different types and sizes of energy storage batteries 202.

[0074] It should be added that the support columns 1022 are arranged alternately with the support frames 1032 along the first direction and the second direction to form a stable support structure, which can improve the overall stability of the battery rack 100 and avoid deformation or inclination caused by uneven force.

[0075] In some embodiments, optionally, the shape of the partition 104 is selectively adapted to the shape of the support frame 1032 or the bearing surface 1038. The partition 104 can better cover and contact the bearing surface 1038 on the support frame 1032. A tight fit is ensured between the partition 104 and the support frame 1032 or the bearing surface 1038, which helps to resist possible sliding during vibration or movement and increases the overall stability of the structure. At the same time, using the partition 104 with a shape adaptation can be installed on the support frame 1032 or the bearing surface 1038 more quickly and accurately, simplifies the assembly process, improves production efficiency, and also reduces the possibility of assembly errors.

[0076] It can be understood that the shape of the partition 104 can be adapted to the overall shape of the support frame 1032. During installation, the partition 104 is equivalent to cooperating with the entire support frame 1032. Alternatively, the shape of the partition 104 is adapted to the shape of a partial structure in the support frame 1032, that is, the bearing surface 1038. At this time, during installation, the partition 104 only needs to cooperate with the bearing surface 1038 to achieve assembly.

[0077] In some embodiments, optionally, the structure of the support frame 1032 is further refined to include a connecting wall 1034 and a bearing wall 1036. Among them, the connecting wall 1034 is responsible for connecting the support frame 1032 with the support column 1022 or other structural components. The connecting wall 1034 realizes a firm connection with other components through the first mating holes 1062 provided thereon.

[0078] The bearing wall 1036 is connected to the connecting wall 1034, and an included angle is formed between the two. One side of the bearing wall 1036 is the bearing surface 1038, which is directly used to contact and support the energy storage battery 202. The bearing wall 1036 improves the load-bearing capacity of the support frame 1032 through the included angle with the connecting wall 1034. Under the action of the included angle, the weight of the energy storage battery 202 can be transmitted from the support frame 1032 to other structures connected thereto, such as the support column 1022, thereby improving the load-bearing capacity and stability of the battery rack 100.

[0079] It can be understood that due to the included angle designed between the connecting wall 1034 and the bearing wall 1036, the support frame 1032 can better bear the vertical load and transfer part of the load to the lateral support. This can reduce the situation of single-point stress on the bearing surface 1038 and avoid deformation or damage caused by excessive concentrated stress.

[0080] Among them, by providing the first mating holes 1062 on the connecting wall 1034, it is used to connect with the support column 1022 or other structural components through bolts, screws or other fasteners.

[0081] Among them, the existence of the first mating hole 1062 ensures the modular installation and flexible assembly of the support frame 1032. This design allows the support frame 1032 to closely cooperate with other components while retaining a certain degree of assembly flexibility, facilitating the adjustment of the position or quantity of the support frame 1032 according to actual requirements. In addition, the standardized design of the mating holes helps to improve the installation accuracy and overall structural stability.

[0082] It can be understood that the support frame 1032 is fixedly connected to the support column 1022 through the first mating hole 1062 on its connecting wall 1034, forming a stable structural framework. The support column 1022 extends along the first direction, while the support frame 1032 extends along the second direction through the connecting wall 1034, forming a complementary support system between the two.

[0083] The angle design between the connecting wall 1034 and the bearing wall 1036 ensures that the support frame 1032 can effectively bear the weight of the battery. The bearing surface 1038 of the bearing wall 1036 provides support in the horizontal position, while the connecting wall 1034 fixes the support frame 1032 on the support column 1022 through the first mating hole 1062, forming an integral framework.

[0084] In some embodiments, optionally, as Figure 3 shown, a limiting protrusion 1024 is provided at one end of the connecting wall 1034 away from the bearing wall 1036, which can effectively limit the position of the energy storage battery 202 on the support frame 1032 and prevent the battery from undergoing excessive displacement or falling off during use. It can be understood that the limiting protrusion 1024 extends transversely from the connecting wall 1034, that is, in a direction parallel to the bearing wall 1036. When the energy storage battery 202 is assembled, the limiting protrusion 1024 can contact the upper and lower edges of the energy storage battery 202 during battery installation to achieve the limitation of the battery position.

[0085] In some embodiments, optionally, a tail-end baffle 1026 is provided and the tail-end baffle 1026 is arranged at one end of the support frame 1032 in the second direction, which can play a role in blocking and limiting the energy storage battery 202 placed on the support frame 1032 and prevent the battery from slipping off from the end of the support frame 1032. It can be understood that when the energy storage battery 202 is inserted into the battery rack 100, the tail end of the energy storage battery 202 will contact the tail-end baffle 1026, preventing it from continuing to move, achieving anti-disconnection and reducing the safety risk.

[0086] Among them, the tail-end baffle 1026 is connected to the connecting wall 1034 and the bearing wall 1036 of the support frame 1032 to form a stable integral structure, and this connection can be welding, bolt connection or other reliable connection methods.

[0087] The end baffle 1026 is disposed at one end of the support frame 1032 along the second direction, and specifically may be perpendicular to the bearing surface 1038, so that the end baffle 1026 can effectively prevent the battery from sliding off the end of the support frame 1032, while not affecting the normal placement and use of the battery on the bearing surface 1038.

[0088] In some embodiments, optionally, the guide plate 1028 is disposed at the entrance end of the support frame 1032, that is, the guide plate 1028 and the end baffle 1026 are respectively disposed at both ends of the support frame 1032 in the second direction, and the energy storage battery 202 is assembled and installed from the side of the guide plate 1028. When the energy storage battery 202 is installed, the guide plate 1028 can first contact the battery during battery installation, guiding the battery to enter the support frame 1032 along the correct direction, while not affecting the placement of the battery on the bearing surface 1038. The guide plate 1028 can play a role in guiding the battery to smoothly enter the support frame 1032, making the battery installation process smoother.

[0089] It can be understood that the presence of the guide plate 1028 can prevent the battery from directly contacting the edge of the support frame 1032 during the installation process, thereby reducing friction and possible collision damage. At the same time, during installation, the battery can be installed on the support frame 1032 more quickly and accurately, saving installation time and improving work efficiency.

[0090] Among them, the guide plate 1028 is connected to the connecting wall 1034, ensuring the stable installation of the guide plate 1028. The specific connection method can be selected according to the actual situation, such as welding, bolt connection, etc.

[0091] In some embodiments, optionally, an assembly hole 1030 is provided on the bearing wall 1036, which can be used to install and fix the energy storage battery 202 or related components. Among them, the size of the assembly hole 1030 in the second direction is larger than the size in the first direction, enabling it to adapt to machining tolerances and assembly errors to a certain extent, and also facilitating subsequent adjustment and maintenance.

[0092] The larger second dimension enables the energy storage battery 202 to have a larger movement space in the second direction during the assembly process, facilitating position adjustment and alignment, thereby improving the efficiency and accuracy of assembly.

[0093] Among them, the assembly hole 1030 is provided on the bearing wall 1036 and can be connected to related components through bolts, rivets or other connecting parts.

[0094] Among them, the assembly hole 1030 can be a rectangular hole or a waist-shaped hole.

[0095] In some embodiments, optionally, such as Figure 2 、 Figure 7 andFigure 8 As shown, the support column 1022 and the support frame 1032 are detachably connected through the cooperation of the first mating hole 1062, the second mating hole 1064 and the connecting member 1066, so as to achieve a firm connection between the support column 1022 and the support frame 1032, and ensure the overall structural stability of the battery rack 100.

[0096] Specifically, the first mating hole 1062 is provided on the connecting wall 1034 of the support frame 1032, and the second mating hole 1064 is provided on the support column 1022. Their positions correspond to each other to ensure that the connecting member 1066 can accurately pass through and perform the connection function. During the actual installation process, it is necessary to align the positions of the support column 1022 and the support frame 1032, align the first mating hole 1062 and the second mating hole 1064, and then insert the connecting member 1066 for fixation.

[0097] It can be understood that when a certain component is damaged or needs to be replaced, it can be conveniently disassembled for repair or replacement without the need to replace the entire battery rack 100, reducing the maintenance cost.

[0098] During transportation and storage, the support column 1022 and the support frame 1032 can be disassembled into smaller components, saving space and facilitating handling and management.

[0099] Among them, the connecting member 1066 passes through the second mating hole 1064 on the support column 1022 and the first mating hole 1062 on the support frame 1032, tightly connecting the two together. The connecting member 1066 can be a bolt, a screw, etc.

[0100] In some embodiments, optionally, as Figure 5 and Figure 6 shown, a paint layer 1082 and an adhesive 1084 are provided on the surface of the support frame 1032. Among them, the paint layer 1082 is provided on the surface of the support frame 1032, which can prevent the support frame 1032 from being corroded and oxidized, and extend the service life of the battery rack 100. In addition, by setting the adhesive 1084 on the upper layer of the paint layer 1082 on the bearing surface, it is convenient to achieve adhesion with the partition 104.

[0101] Among them, the thickness of the paint layer 1082 is greater than or equal to 100 microns to ensure the anti-corrosion effect. In addition, by connecting through an adhesive layer between the paint layer 1082 and the partition 104, the surface of the support frame 1032 can be prevented from directly contacting the energy storage battery 202, avoiding the energy storage battery 202 from damaging the paint layer 1082.

[0102] Among them, the paint layer 1082 is directly coated on the surface of the support frame 1032 to form a protective film. The thickness of the adhesive 1084 is not greater than 0.3 mm, which can provide sufficient adhesive force without increasing too much thickness, ensuring that the partition 104 can be stably fixed on the bearing surface and will not fall off or shift during use.

[0103] The paint layer 1082 covers the entire surface of the support frame 1032, including the connecting wall 1034 and the bearing wall 1036. The adhesive 1084 is located on the paint layer 1082 of the bearing surface and has a large contact area with the partition 104 to provide sufficient connection ability.

[0104] As Figure 10 shown, an embodiment of the second aspect of the present application provides an energy storage device 200, including a battery rack 100 and an energy storage battery 202. The battery rack 100 provides a stable support structure for the energy storage battery 202, ensuring that the energy storage battery 202 can be safely placed therein and avoiding situations such as shaking, displacement or tipping of the battery during use.

[0105] The design of multiple frame bodies 102 enables the energy storage batteries 202 to be arranged in an orderly manner in the battery rack 100, facilitating the management and maintenance of the batteries and also being beneficial to improving the space utilization rate.

[0106] The energy storage battery 202 is located inside the battery rack 100. The support frame 1032 and the partition 104 of each frame body 102 work together to fix the energy storage battery 202 in a specific position, keeping a certain distance between the batteries, which is beneficial to heat dissipation and maintenance.

[0107] Since the energy storage device 200 includes any one of the above battery racks 100, it has the beneficial effects of any one of the above battery racks 100, which will not be elaborated here.

[0108] Furthermore, in the second direction, the size of the battery rack 100 is larger than the size of the energy storage battery 202, and there is a difference of 2 mm to 4 mm between the two. The size of the battery rack 100 is slightly larger than the size of the energy storage battery 202, providing a certain margin for the installation of the energy storage battery 202. This can ensure that the energy storage battery can be smoothly installed into the battery rack 100 and is also convenient for battery replacement and maintenance.

[0109] In a specific embodiment, due to the high cost of stainless steel, the current energy storage box battery rack 100 is generally formed by cold-rolled steel plate. After the battery rack 100 is painted, its surface friction coefficient is about 0.15-0.2. At present, the weight of the battery pack of 1P52S is about 330Kg, and the weight of the battery pack of 1P104S is about 650Kg. μ is taken as 0.2. When the battery pack is pushed into the battery rack 100, its maximum friction force is 66kgf and 130kgf respectively. Without the help of special tooling, the huge friction force will make it very difficult to push and pull the battery pack into and out of the battery rack 100, especially the highest battery pack operator needs to use climbing equipment, which further increases the danger of operation. The bottom structure of the battery pack may have sharp edges, and direct friction with the battery rack 100 will cause damage to the paint layer 1082. When the metal is exposed, the battery rack 100 will inevitably rust over time. Due to the position of the battery pack fixing holes, the current length of the battery rack 100 is a fixed value and cannot absorb the processing tolerance. To solve the installation tolerance, the fixing holes on the battery rack 100 are oblong holes. When the nuts are loosened by transportation vibration, the battery pack will slip, which may cause leakage in severe cases.

[0110] In order to solve the above problems, this specific embodiment proposes a battery rack solution, including: a battery rack column (i.e., a support column); a battery rack body (i.e., a support frame), which adopts SGCC and is formed by bending a 4.0 mm steel plate, and the effective length between the fixed end and the tail end is as follows: Figure 4 The dimension A shown in the figure is the length from the fixed end of the battery pack to its own tail end. Figure 9 The dimension B shown in the figure is AB = 3 ± 1 mm; the stainless steel plate SUS304 (i.e. the partition) is 0.2 mm thick and is arranged on the horizontal bearing surface of the battery rack body; the silicone structural adhesive (i.e. the bonding adhesive) complies with JT / T 811-2011 "Relevant Provisions on Container Sealant"; the hexagon socket M6 countersunk screw (i.e. the connector) is grade 10.9.

[0111] The battery rack body is connected to the battery rack columns by bolts. Before connection, the battery rack and the columns need to be sprayed separately.

[0112] The silicone structural adhesive is used for bonding between the battery rack body and the stainless steel plate.

[0113] The battery rack column specifications of this application are 100mm×100mm×4mm and 2640mm high;

[0114] The battery rack body of the present application is 2170mm long and 50mm wide;

[0115] The stainless steel plate of this application is 2088mm long and 45mm wide;

[0116] More specifically, the shape of the stainless-steel plate is the same as that of the battery rack body to which it adheres;

[0117] The stainless-steel plate is adhesively bonded to the horizontal bearing surface of the battery rack body in the same direction. After the bonding of the battery rack body and the stainless-steel plate assembly is completed, it is then fastened to the side of the battery rack column.

[0118] The battery rack includes: battery rack columns, battery rack body, stainless-steel plate, silicone structural adhesive, and hexagon socket M6 countersunk head screws, and does not include the battery pack. The battery pack is only used to illustrate the installation process.

[0119] According to the requirements of the energy storage device, set the size value of the battery rack. According to the preset size value, process and inspect the dimensions of the battery rack columns and the battery rack body respectively to ensure that the dimensions meet the set value.

[0120] According to the design value, laser cut the stainless-steel plate. The upper and lower limits of the length and width tolerance of the stainless-steel plate are +0mm and -1mm.

[0121] Spray indoor paint on the battery rack body. The thickness of the paint layer is not less than 100μm. After the paint layer is cured, use a brush to evenly apply the silicone structural adhesive on the horizontal bearing surface of the battery rack body. The thickness of the glue application is not more than 0.3mm. Then align the stainless-steel plate with the edge of the battery rack body and press it flat on the bonding surface, and clamp it with a strong clamp. The curing time needs to be greater than 8 hours.

[0122] Use hexagon socket M6 countersunk head screws to fix the battery rack body and the stainless-steel plate assembly on the battery rack column to complete the general assembly of the left sheet of the battery rack.

[0123] Refer to the above steps to complete the general assembly of the right sheet of the battery rack.

[0124] Weld the left sheet and the right sheet together to form an integral battery rack.

[0125] Push the battery pack along the surface of the stainless-steel plate. If necessary, lubricating grease can be applied in advance to further reduce the friction force.

[0126] Use the battery pack connecting piece to lock the battery pack and the battery rack body. Due to the tolerance of the battery rack body (after being pushed in place, there should be a tolerance of 3±1mm remaining between the tail of the battery pack and the inner end of the battery rack body), the battery pack can be correctly connected to the locking piece, and it remains stationary after being locked with an M8 screw (the locking piece has a round hole of D8.5mm) in cooperation with thread sealant to ensure that there is no slip during transportation.
