Description

Technical Field

[0001] The present invention relates to the fields of modern logistics and energy storage, and in particular to a battery bracket and an energy storage device. Background Art

[0002] In the field of modern logistics and energy storage, energy storage devices are used more and more widely as a standardized and modular transportation and storage tool. However, with the diversification of usage scenarios and the improvement of safety requirements, traditional energy storage devices have gradually exposed their shortcomings in structural strength, especially in extreme environments such as earthquakes.

[0003] Currently, the IEEE693 standard has clear and strict requirements for high seismic performance to ensure that energy storage equipment can maintain its basic functions and prevent secondary disasters when an earthquake occurs. However, existing energy storage devices often do not fully consider these high seismic requirements during the design and manufacturing process, resulting in major safety hazards in actual applications.

[0004] Especially in application scenarios located in earthquake zones, such as coastal areas with frequent tsunamis or mountainous areas with frequent geological activities, the structural strength of the energy storage device is directly related to the safety of the internal energy storage equipment and the stable operation of the entire system. In addition, in some complex application scenarios, such as temporary emergency energy stations or long-term energy supply points in remote areas, energy storage devices also need to face harsh natural environments and changing usage conditions. Summary of the invention

[0005] The main purpose of the present invention is to provide a battery bracket and energy storage device, which have good stability and shock resistance and can effectively protect the battery module installed inside from the influence of the external environment.

[0006] To achieve the above objectives, some embodiments of the present invention provide a battery bracket, comprising: A plurality of column groups, each column group is spaced apart along a first direction, each column group includes a plurality of columns spaced apart along a second direction, and the first direction intersects the second direction; A plurality of cross beams, each of which extends along a first direction, and the cross beams connect at least two columns arranged along the first direction; A plurality of longitudinal beams, each longitudinal beam extending along the second direction, and the longitudinal beam connects at least two columns arranged along the second direction; A plurality of shock absorbing structures are provided, each of which comprises a reinforcing beam. Along a first direction, two ends of the reinforcing beam are respectively connected to two adjacent columns, and the reinforcing beam is arranged obliquely relative to the transverse beam or the longitudinal beam.

[0007] In some embodiments, the column includes a vertically extending column; or, the column includes two vertically extending columns, and the two columns abut against each other along the first direction or the second direction.

[0008] In some embodiments, the column includes two vertically extending columns, and the two columns are abutted against each other along the second direction; and the two ends of the reinforcing beam along the first direction are correspondingly connected to the two columns.

[0010] In some embodiments, the shock absorbing structure includes at least two reinforcement beams, the reinforcement beams are cross-arranged, and each reinforcement beam is inclined relative to the first transverse direction.

[0011] In some embodiments, the shock absorbing structure further comprises a support beam connecting at least two reinforcement beams.

[0012] In some embodiments, the first axis is parallel to the second direction, and the first axis passes through the intersection of the two reinforcement beams, and the support beams are sequentially connected to the reinforcement beams around the circumference of the first axis.

[0013] In some embodiments, the support beams are sequentially connected to the reinforcement beams in a circumferential direction around the first axis to enclose a rectangular structure.

[0014] In some embodiments, the battery support further includes a plurality of battery layers extending along the second direction, each of the battery layers is connected to a plurality of columns arranged at intervals along the second direction, and the battery layers are used to carry the battery modules.

[0015] An embodiment of the second aspect of the present invention provides an energy storage device, comprising: A battery holder according to any one of the above embodiments; A battery module connected to the battery bracket; and The outer shell defines a receiving cavity, and the battery holder and the battery module are both arranged in the receiving cavity.

[0016] According to the above embodiments, the beneficial effects of the present invention are: The battery support of the present invention includes a plurality of column groups, a crossbeam, a longitudinal beam and a shock absorbing structure. The column groups are spaced apart along a first direction, and each column group is composed of a plurality of columns spaced apart along a second direction, wherein the first direction and the second direction intersect each other. The crossbeam extends along a first direction and connects at least two columns arranged in the first direction; the longitudinal beam extends along a second direction and connects at least two columns arranged in the second direction. The two ends of the reinforcing beam in the shock absorbing structure are respectively connected to two adjacent columns, and are arranged obliquely relative to the crossbeam or the longitudinal beam.

[0026] Reference below Figures 1 to 8 The battery bracket and energy storage device according to the embodiments of the present invention are described.

[0027] Reference Figure 1 and Figure 6 In some embodiments, the battery support includes a plurality of columns 110 groups 100, a crossbeam 200, a longitudinal beam 300 and a shock absorbing structure 800. The columns 110 groups 100 are spaced apart along a first direction X, and each column 110 group 100 is composed of a plurality of columns 110 spaced apart along a second direction Y, wherein the first direction X and the second direction Y intersect each other. The crossbeam 200 extends along the first direction X and connects at least two columns 110 arranged in the first direction X; the longitudinal beam 300 extends along the second direction Y and connects at least two columns 110 arranged in the second direction Y. The two ends of the reinforcing beam 810 in the shock absorbing structure 800 are respectively connected to two adjacent columns 110, and are inclined relative to the crossbeam 200 or the longitudinal beam 300.

[0028] On the one hand, through this structural design, the crossbeam 200 and the longitudinal beam 300 together form a grid-like basic frame, which can provide stable support, and the battery module is located in the grid frame. On the other hand, the reinforcing beam 810 in the shock-absorbing structure 800 forms a certain angle with the crossbeam 200 or the longitudinal beam 300, which not only increases the rigidity of the overall structure, but also can absorb part of the energy when impacted by external force, thereby achieving a shock-absorbing effect. Specifically, this oblique reinforcing beam 810 can provide additional support, and when subjected to vibration or impact, it can disperse the force through its own inclination angle, thereby reducing the impact on the overall structure.

[0029] It is understandable that the design of the reinforcing beam 810 takes into account the principles of mechanics. When the reinforcing beam 810 is connected to the column 110, they together form a stable triangular structure. This geometric shape has high rigidity and torsion resistance. Therefore, even under extreme conditions, such as severe vibration or accidental collision, the battery holder of the present application can maintain its structural integrity and ensure the safety of the internal battery. Specifically, when an external force is applied to the battery holder, the reinforcing beam 810 has a certain angle deviation due to its tilted arrangement, which enables it to more effectively transmit the force to the column 110 connected to it. Since the direction of the force is changed, the reinforcing beam 810 can help absorb and diffuse the vibration energy, reduce the vibration directly transmitted to other structural parts, and thus improve the overall stability and durability of the battery holder. Therefore, regardless of the shape, number and other structural elements of the reinforcing beam 810, the shock absorbing structure 800 designed by such a principle is within the scope of protection of the present application. For example, the reinforcing beam 810 can be a straight beam, and the reinforcing beam 810 can also be an arc beam or a beam of other irregular shapes.

[0030] This arrangement enables the battery holder to have good stability and earthquake resistance, and can effectively protect the battery modules installed inside from the influence of the external environment, while improving the safety of the entire energy storage device.

[0031] Furthermore, in some embodiments, the design of the reinforcing beam 810 can be further optimized, for example, by using a material with higher strength, or by designing the reinforcing beam 810 into a corrugated shape to increase its elastic deformation capacity. In addition, the angle between the reinforcing beam 810 and the crossbeam 200 or the longitudinal beam 300 can be adjusted according to actual needs to adjust the shock absorption effect and meet the needs of different application scenarios. In addition, considering cost control, it is also possible to choose to use standard profiles for assembly to facilitate large-scale production. Through these extended designs, the battery holder not only maintains the original function, but also improves the economy and practicality.

[0032] Of course, it is understandable that, in some embodiments, the force effect of the reinforcing beam 810 can be adjusted by changing the thickness of the reinforcing beam 810 so that the battery bracket can obtain a better shock-absorbing effect.

[0033] It is understandable that in some embodiments, the column 110 can be made of high-strength materials, such as aluminum alloy or steel, to ensure sufficient load-bearing capacity. At the same time, the longitudinal beam 300 and the cross beam 200 can also be made of similar materials to ensure that they have good bending strength. The inclination angle of the reinforcing beam 810 can be adjusted according to the load conditions in actual applications, and the angle that maximizes the structural rigidity is usually selected. In addition, the connection between the reinforcing beam 810 and the column 110 can be welding or bolting, depending on the requirements of the manufacturing process. Such a design not only enhances the overall stability of the battery bracket, but also improves its ability to resist external impacts and prolongs its service life.

[0034] It is understandable that in some embodiments, in order to adapt to different use environments or increase the load-bearing capacity of the battery rack, the number of columns 110 in the column 110 group 100 can be adjusted according to actual needs. For example, more columns 110 can be added to enhance the rigidity of the overall frame; at the same time, the sizes of the longitudinal beams 300 and the cross beams 200 can also be changed accordingly according to specific application requirements to ensure optimal structural performance.

[0035] Reference Figures 4 to 6 In some embodiments, the column 110 can be designed as a single vertically extending column 111, or a form formed by a combination of two vertically extending columns 111 in parallel, and the two columns 111 can abut against each other in the first direction X or the second direction Y. On the one hand, such a design increases the density of the column 110 group 100; on the other hand, such a flexible design allows the selection of a suitable column 110 configuration scheme according to different load requirements. Specifically, when the column 110 is composed of a single column 111, it directly provides a supporting force in the vertical direction, which is suitable for occasions with high vertical load requirements. When the column 110 is composed of two columns 111 and abuts against each other in the first direction X or the second direction Y, the overall stiffness and stability of the column 110 can be significantly enhanced. Especially for those application scenarios that need to withstand large lateral forces, the double column 111 design helps to better resist bending deformation. Both of these different column 110 design schemes can effectively improve the overall load-bearing capacity and stability of the battery bracket, ensuring that the battery module is safely and reliably installed thereon. In particular, the double-column 111 design can also provide additional torsional resistance, which is crucial for maintaining the long-term operational stability of the entire energy storage system.

[0036] It is understandable that in some embodiments, in order to further enhance the function of the column 110, it is possible to consider surface treatment of the column 110, such as plating or spraying anti-corrosion paint, to extend the service life. If the column 110 is composed of two cylinders 111, a buffer gasket can be added between the contact surfaces of the two to reduce vibration transmission and prevent metal-to-metal wear. In addition, a modular design concept can be introduced, that is, the different components of the column 110 can be quickly replaced or upgraded according to specific needs, which is not only convenient for maintenance, but also enhances the adaptability and scalability of the product. Through these improvement measures, the battery holder can be more in line with the diverse needs in practical applications.

[0037] It is understandable that the connection between the two parallel columns 111 can be achieved by welding, bolting or other suitable fixing means. Such a combined structure not only enhances the strength of the column 110 itself, but also enables the battery holder to withstand greater weight without deformation. In addition, this double column 111 structure can better resist external forces from different directions, ensuring that the battery holder can maintain good stability even during transportation.

[0038] Furthermore, in some embodiments, two parallel columns 111 can be fixed together by additional connecting members (such as metal plates or reinforcement strips) to further improve their efficiency as a whole. The advantage of this is that even under extreme conditions, such as strong lateral impact, it can ensure that there is no relative displacement between the columns 110, maintaining the shape integrity of the entire battery bracket.

[0039] Further, refer to Figure 6In some embodiments, the column 110 in the battery support includes two vertically extending columns 111, and the two columns 111 abut against each other along the second direction Y. The two ends of the reinforcing beam 810 along the first direction X are respectively connected to two adjacent columns 110. Specifically, one end of the reinforcing beam 810 is connected to a group of columns 111 arranged in parallel, and the other end is connected to another group of columns 111 arranged in parallel corresponding to it along the first direction X. When the reinforcing beam 810 is connected to a more stable and sturdy combination of columns 111, it can distribute the load more evenly and reduce the risk of a single column 111 being subjected to excessive pressure. It can be understood that the use of two columns 111 abutting along the second direction Y to form a composite column 110 can significantly enhance the bending strength and lateral stiffness of the column 110. When subjected to lateral force, the contact surface between the two columns 111 can bear the load together, thereby dispersing the stress and reducing the bending or twisting deformation of the single column 111 due to local stress concentration. In addition, the reinforcing beam 810 connects adjacent columns 110 along the first direction X, further enhancing the overall structural stability and torsional resistance of the bracket. At the same time, since the reinforcing beam 810 is inclined relative to the first cross beam 200 or the first longitudinal beam 300, it can also provide additional supporting force in a direction perpendicular to its own length, thereby improving the rigidity of the overall frame.

[0040] Such a design not only increases the load-bearing capacity of each column 110, but also improves the ability of the entire battery support to resist external impact, ensuring the safe and stable installation of the battery module. It is particularly suitable for application scenarios that need to withstand large lateral forces, such as mobile energy storage equipment or fixed energy storage systems in earthquake-prone areas.

[0041] It is understandable that in some embodiments, in order to optimize the design of the above-mentioned double cylinders 111, a connector, such as a metal splint or a high-strength adhesive, can be added between the two cylinders 111 to further strengthen the bonding strength between the two. In addition, it is also possible to consider special treatment of the contact surfaces of the two cylinders 111, such as increasing the friction coefficient by knurling, embossing, etc., to prevent slippage during long-term use. In addition, the design of the reinforcing beam 810 can also be more flexible and diverse, such as using beams with different cross-sectional shapes (such as T-shaped, L-shaped) to adapt to different mechanical requirements, or using materials with better ductility to make the reinforcing beam 810, so that it can have a certain flexibility while ensuring sufficient strength to absorb more vibration energy. These improvement measures will help to further improve the overall performance of the battery holder.

[0042] Reference Figure 6In some embodiments, the end of the reinforcing beam 810 in the battery support is clamped between two columns 111 abutting against each other. This shows that the reinforcing beam 810 is not simply connected to the column 110, but is more firmly combined through an embedded connection method. The end of the reinforcing beam 810 is clamped between the two columns 111, which can be regarded as a clamping and fixed connection form. This method utilizes the close fit between the two columns 111 and the physical constraints of the end of the reinforcing beam 810, so that the connection between the reinforcing beam 810 and the column 110 is more reliable. When subjected to external force, the clamping force between the reinforcing beam 810 and the column 111 will increase, thereby effectively transmitting and dispersing the load and reducing the possible loose connection problem. In addition, this clamping connection also helps to limit the degree of freedom of the reinforcing beam 810, reduce its displacement in unintended directions, and further ensure the stability of the entire support structure.

[0043] The design of sandwiching the end of the reinforcing beam 810 between the two columns 111 greatly improves the reliability of the connection between the reinforcing beam 810 and the column 110, and reduces the risk of structural damage due to connection failure. This is crucial to maintaining the long-term safe operation of the entire battery rack, especially in working environments that are often subject to vibration or impact. Such a connection method can better protect the battery module from damage.

[0044] It is understood that in some embodiments, in order to enhance structural stability, the reinforcing beam 810 may be made of high-strength material, and its shape and size are designed to fit the space between the columns 110. The connection between the reinforcing beam 810 and the column 110 can be achieved by welding, bolts or other fixing methods to ensure the integrity and strength of the structure. In addition, this embedded design also helps to improve the battery bracket's resistance to vibration and impact, because the reinforcing beam 810 can provide support in different directions, enhancing the rigidity of the overall frame.

[0045] Furthermore, in some embodiments, in order to enhance the effect of the clamping connection, a specific slot or protrusion may be designed at the end of the reinforcing beam 810 to match the pre-set groove inside the column 111, which not only simplifies the assembly process, but also ensures the consistency and accuracy of the connection position. In addition, anti-rust oil may be applied or a sealing gasket may be installed on the contact surface between the reinforcing beam 810 and the column 111 to prevent corrosion problems and extend service life. For applications requiring higher seismic performance, elastic materials such as rubber gaskets may be filled between the reinforcing beam 810 and the column 111 to absorb vibration energy and further improve the shock absorption effect. These extended measures help to further improve the overall performance and durability of the battery holder.

[0046] Reference Figures 6 to 8In some embodiments, the shock absorbing structure 800 of the battery holder includes at least two reinforcing beams 810, which are cross-arranged and each of which is tilted relative to the first cross beam 200. This design improves the stability of the overall structure and provides an effective shock absorption function through the cross-arrangement of multiple reinforcing beams 810. Such an arrangement enables the reinforcing beams 810 to provide support at different angles, forming a more complex force distribution network. The cross-arranged reinforcing beams 810 can provide support in different directions, thereby enhancing the rigidity and torsion resistance of the entire frame. When impacted by external force, the cross-arranged reinforcing beams 810 can disperse the load and reduce stress concentration in a single direction. When external force acts on the battery holder, the cross-arranged reinforcing beams 810 can effectively disperse the force and reduce the pressure on any single component, thereby improving the stability and shock resistance of the entire structure.

[0047] At the same time, since the reinforcing beam 810 is inclined relative to the first cross beam 200, this not only increases the stability of the structure, but also enables the reinforcing beam 810 to provide additional supporting force in a direction perpendicular to its own length, further improving the rigidity of the overall structure.

[0048] The cross-arranged reinforcing beams 810 can form a more stable triangular support structure. This layout helps to absorb part of the energy through the interaction between the reinforcing beams 810 when vibration or impact occurs, thereby achieving a shock-absorbing effect and making the battery holder less likely to deform when subjected to external forces. This design improves the overall stability and seismic resistance of the battery holder, ensuring the safety and reliability of the battery module in various working environments. Especially in application scenarios that need to withstand multi-directional loads, such as mobile energy storage equipment or fixed energy storage systems in earthquake-prone areas, this structure can effectively protect the battery module from damage.

[0049] It is understandable that in some embodiments, in order to further optimize the shock absorption effect, a reinforcing beam 810 of different materials and cross-sectional shapes can be used. For example, the reinforcing beam 810 is made of high-strength alloy steel or composite materials to increase its strength and durability. In addition, the cross-sectional shape of the reinforcing beam 810 can be designed to be a complex shape such as an I-beam to meet different mechanical requirements. In addition, an elastic gasket or a rubber buffer can be added at the connection between the reinforcing beam 810 and the column 110 to further absorb vibration energy. These improvement measures help to improve the overall performance and service life of the battery holder.

[0050] It is understandable that the cross-arranged reinforcing beams 810 can also adjust their inclination angles and relative positions according to actual needs in order to more effectively cope with loads in a specific direction. For example, if the battery holder is expected to be subjected to vibration or impact from a specific direction, the angle of the reinforcing beam 810 can be optimized accordingly to better absorb the energy in that direction. In addition, the cross-arrangement also increases the redundancy of the structure. Even if a reinforcing beam 810 is damaged, the other reinforcing beams 810 can still maintain the integrity of the structure. Specifically, in some embodiments, the cross angle between the reinforcing beams 810 can be adjusted according to actual needs, and 45 degrees or 60 degrees are usually selected to obtain the best force transmission effect. In addition, the connection between the reinforcing beam 810 and the column 110 can be achieved by welding, bolting, etc., to ensure the stability of the structure. When the battery holder is vibrated, the cross-arranged reinforcing beams 810 can effectively convert the vibration energy into internal stress in the structure, reducing the impact on the battery. At the same time, the inclined design also allows the reinforcing beam 810 to better cooperate with the longitudinal beam 300 and the cross beam 200 to jointly maintain the stability of the overall frame and prevent damage caused by local stress concentration.

[0051] Reference Figure 7 In some embodiments, the shock absorbing structure 800 includes a support beam 820 in addition to the cross-arranged reinforcement beams 810, and the support beam 820 is used to connect at least two reinforcement beams 810. The function of the support beam 820 is to further strengthen the connection between the reinforcement beams 810. The support beam 820 connects the cross-arranged reinforcement beams 810 together to form a more stable overall structure. This connection method can not only enhance the synergy between the reinforcement beams 810, but also better transmit and disperse the load when subjected to external force, avoiding damage caused by excessive force on a certain point. The existence of the support beam 820 can also limit the degree of freedom of the reinforcement beam 810 and reduce its displacement in unexpected directions, thereby further improving the rigidity and stability of the entire shock absorbing structure 800. In addition, the support beam 820 itself can also provide additional support in the direction perpendicular to its length, thereby enhancing the torsion resistance of the overall frame. The support beam 820 and the reinforcement beam 810 form a whole, which can jointly bear a larger load, and also improve the rigidity and stability of the entire shock absorbing structure 800.

[0052] The design of the support beam 820 also takes into account the principles of mechanics. Its existence is not only to simply connect the reinforcing beams 810 together, but also plays a key role in force transmission in the entire structure. The support beam 820 can help distribute the forces between the reinforcing beams 810 and avoid local stress concentration, thereby extending the service life of the battery holder. By introducing the support beam 820, the shock absorbing structure 800 of the battery holder becomes more sturdy and reliable, and can more effectively resist external shocks and vibrations. This design not only improves the overall stability of the battery holder, but also extends its service life and ensures the safe operation of the battery module. Especially for those application scenarios that require long-term operation and face a variety of load conditions, the addition of support beam 820 provides additional safety protection.

[0053] It is understood that in some embodiments, in order to further enhance the function of the support beam 820, a material with a high strength-to-weight ratio, such as aluminum alloy or carbon fiber composite material, can be selected to reduce weight and maintain sufficient strength. In addition, welding, bolting or riveting are used at the connection between the support beam 820 and the reinforcement beam 810 to ensure the firmness of the connection point and ensure that the two are tightly combined without relative displacement. In some embodiments, a metal splint or a high-strength adhesive can also be added at the connection to further strengthen the bonding strength between the two.

[0054] Of course, it is understandable that the support beam 820 can be designed into different cross-sectional shapes, such as rectangular, circular or special-shaped cross-sections, to meet different mechanical requirements. For example, a rectangular cross-section can provide greater bending strength, while a circular cross-section is conducive to uniform load distribution. In some embodiments, an elastic element, such as a spring or a rubber gasket, is added between the support beam 820 and the reinforcing beam 810 to absorb more vibration energy and improve the shock absorption effect.

[0055] In addition, the position layout of the support beam 820 should take into account the mechanical balance of the overall structure. For example, it can be arranged near the intersection of the reinforcing beam 810 to more effectively transmit force. This design allows the entire battery rack to maintain good stability and safety when facing a complex and changing external environment.

[0056] Reference Figures 1 to 6In some embodiments, the shock absorbing structure 800 of the battery holder includes at least two reinforcing beams 810, and these reinforcing beams 810 are arranged crosswise. The first axis is parallel to the second direction Y, and the first axis passes through the intersection of the two reinforcing beams 810, and the support beam 820 connects the reinforcing beams 810 in sequence around the circumference of the first axis. This design further connects the cross-arranged reinforcing beams 810 through the support beam 820 to form a more stable overall structure, thereby increasing the stability of the entire shock absorbing structure 800. When an external force acts on the battery holder, through this specific layout between the support beam 820 and the reinforcing beam 810, the support beam 820 can effectively transmit and disperse the load, reduce local stress concentration, and thus protect the battery holder from damage. Moreover, such a layout forms a centrally symmetrical structure, which helps to evenly distribute the force, so that the entire battery holder can disperse the load more evenly when it is impacted. In addition, the layout of the support beam 820 around the first axis also enhances the torsional resistance of the entire structure and ensures the stability of the structure in different directions.

[0057] The design of the support beam 820 connecting the reinforcing beam 810 circumferentially along the first axis not only provides additional lateral support, but also enhances the rigidity of the entire frame. In this way, the battery holder can maintain its geometric shape unchanged even when subjected to forces from different directions, reducing the risk of deformation. The connection between the support beam 820 and the reinforcing beam 810 can be achieved by welding, bolts or other fasteners to ensure the stability of the structure. In addition, the presence of the support beam 820 also improves the seismic performance of the shock absorbing structure 800, because it can provide additional support at multiple points, thereby enhancing the torsion resistance and durability of the overall structure. This design improves the overall rigidity and stability of the battery holder, enabling it to better resist external shocks and vibrations. This not only improves the safety of the battery module, but also extends the service life of the battery holder, and is particularly suitable for application scenarios that require long-term operation and face a variety of load conditions.

[0058] It is understood that, in some embodiments, the support beam 820 may be made of high-strength alloy steel or composite material to improve its strength and durability.

[0059] It is understood that in some embodiments, the connection between the support beam 820 and the reinforcement beam 810 can be welded, bolted or riveted to ensure the firmness of the connection point. A metal splint or a high-strength adhesive can also be added at the connection to further strengthen the bonding strength between the two.

[0060] It is understood that in some embodiments, the support beam 820 can be designed into different cross-sectional shapes, such as rectangular, circular or special-shaped cross-sections, to meet different mechanical requirements. For example, a rectangular cross-section can provide greater bending strength, while a circular cross-section is conducive to uniform load distribution.

[0061] It is understandable that, in some embodiments, an elastic element, such as a spring or a rubber gasket, is added between the support beam 820 and the reinforcement beam 810 to absorb more vibration energy and improve the shock absorption effect.

[0062] It will be appreciated that in some embodiments, the support beams 820 may be connected to the reinforcement beams 810 in a specific order, such as from top to bottom or from left to right, to ensure even distribution of loads and avoid imbalance in the structure.

[0063] It is understandable that in some embodiments, the connection method of the support beam 820 around the first axis can be a continuous annular connection or a segmented connection, which depends on the actual manufacturing process and design requirements. If an annular connection is adopted, the support beam 820 will form a complete closed loop, further enhancing the integrity of the structure; if it is a segmented connection, each section of the support beam 820 needs to be precisely docked to ensure that there is no gap. In either case, the key is to ensure that all connection parts have sufficient strength and rigidity to withstand the maximum load that may be encountered. In addition, in order to improve the durability of the structure, gaskets can be added to the contact surface of the support beam 820 and the reinforcement beam 810 or a special coating can be used to prevent wear and corrosion.

[0064] Reference Figure 7 In some embodiments, the support beam 820 is connected to the reinforcing beam 810 in sequence around the circumference of the first axis to form a rectangular structure. This rectangular structure is enclosed by the support beam 820 and the reinforcing beam 810. This closed structure forms a complete frame between the reinforcing beams 810, thereby greatly enhancing the rigidity and stability of the entire shock absorbing structure 800. The closed characteristics of the rectangular structure can also provide additional support force, especially in the direction perpendicular to the length of the support beam 820. When subjected to external force, the closed rectangular structure can more effectively transfer and disperse the load, reduce local stress concentration, and provide better torsional resistance. When the battery holder is subjected to vibration or impact, the rectangular structure can evenly distribute the load and prevent local stress concentration, thereby protecting the safety of the battery.

[0065] It is understood that in some embodiments, in order to further improve the strength of the rectangular structure, the material selection and size design of the support beam 820 and the reinforcement beam 810 are considered. For example, the support beam 820 may be made of high-strength steel, while the reinforcement beam 810 adjusts the cross-sectional size and thickness as needed to achieve the best load-bearing capacity. In addition, each connection point in the rectangular structure needs to be reinforced, such as using high-strength bolts or welding, to ensure that the connection does not become a weak link. The rectangular structure is also easy to install and maintain because its regular shape helps to standardize the production and assembly process.

[0066] It is understandable that in some embodiments, in order to form a rectangular structure, usually, the support beams 820 at the four corners will be specially reinforced to ensure that the four corners of the rectangular frame are strong enough. In addition, special attention should be paid to the connection points between the support beam 820 and the reinforcing beam 810 to ensure that the connection does not become a weak link. The rectangular structure formed in this way can not only resist pressure in the vertical direction, but also cope well with shear forces in the horizontal direction. In addition, transverse or longitudinal auxiliary beams can be added inside the rectangular frame to further enhance its bending resistance and overall rigidity. The shock absorbing structure 800 designed in this way can provide all-round protection for the battery and maintain good functionality even in extreme environments.

[0067] Reference Figure 5 In some embodiments, the battery holder further comprises a plurality of battery layers extending along the second direction Y. These battery layers are connected to a plurality of columns 110 arranged at intervals along the second direction Y. The main function of the battery layer is to carry the battery module. Since there is a solid connection between the battery layer and the column 110, this provides a stable support platform for the battery module placed thereon, thereby ensuring the safety and stability of the battery module. Through such a design, the weight of the battery module can be effectively dispersed, and the pressure on a single column 110 is reduced, thereby increasing the overall strength and reliability of the entire battery holder structure.

[0068] It is understandable that in some embodiments, in order to further improve the load-bearing capacity of the battery layer and the stability of the overall bracket, additional reinforcement measures may be provided on the battery layer. For example, a support frame may be added under the battery layer or a reinforcing material may be used to increase the rigidity of the layer. In addition, high-strength bolts or other types of fasteners may be used at the connection point between the layer and the column 110 to ensure the firmness of the connection part. This design not only improves the support effect on the battery module, but also extends the service life of the entire battery bracket. In addition, considering that battery modules of different sizes and weights may require different support structures, the design of the battery layer can also be adjusted according to actual needs, such as changing the thickness, width or material of the layer, etc., to meet the installation requirements of battery modules of various specifications. This not only ensures the good adaptability of the battery bracket to various types of battery modules, but also maintains its structural flexibility and extensibility.

[0069] Reference Figures 1 to 8, an embodiment of the second aspect of the present invention proposes an energy storage device, including a battery holder according to any of the aforementioned embodiments, and the energy storage device also includes a battery module and an outer shell. The battery module is connected to the battery holder, and the outer shell defines a receiving cavity, in which the battery holder and the battery module thereon are housed. By placing the battery holder and the battery module in a closed outer shell, the internal components can be effectively protected from external environmental factors (such as temperature changes, moisture, etc.), while also preventing the risk of accidental electric shock, thereby ensuring safe use.

[0070] It is understandable that in some embodiments, the design of the outer shell can be adjusted accordingly according to the needs of the specific application scenario. For example, the outer shell can be made of a material with good insulation and corrosion resistance to enhance resistance to adverse external conditions. In addition, the outer shell can also be equipped with heat dissipation holes, vents and other facilities to timely discharge the heat generated by the battery operation and maintain a suitable internal operating temperature range. For some special occasions, such as mobile energy storage systems, the outer shell also needs to consider the lightweight design principle and select lightweight but durable materials for easy handling. In addition, the connection method between the outer shell and the battery holder is also one of the important considerations. Usually, fasteners that are easy to disassemble are used to facilitate later maintenance and repair operations. Finally, in order to meet the needs of different user groups, the surface treatment process of the outer shell will also be different, such as spraying anti-rust paint, covering warning signs, etc., to achieve the purpose of beauty and practicality.

[0071] Reference Figure 1 In some embodiments, the energy storage device further includes a bottom cross beam 400 and a bottom side beam 600. The bottom cross beam 400 is arranged in a horizontal direction to support the bottom of the entire energy storage device to ensure the stability and carrying capacity of the energy storage device. The bottom side beam 600 is arranged along the side of the energy storage device to enhance the rigidity of the side of the energy storage device and also provide additional support for the battery holder. The bottom cross beam 400 and the bottom side beam 600 together constitute the basic frame of the energy storage device, providing a solid foundation for the internal battery holder and other components.

[0072] It is understandable that, in some embodiments, the design of the bottom cross beam 400 and the bottom side beam 600 takes into account various load conditions that may be encountered during the transportation of the energy storage device. For example, the bottom cross beam 400 may be designed to have a larger cross-sectional area to better disperse the weight and reduce the pressure on the ground. The bottom side beam 600 may adopt a thickened or special cross-section design to improve its bending strength and ensure that the energy storage device will not be lateral deformed during transportation or stacking. In addition, the material of the bottom cross beam 400 and the bottom side beam 600 is usually selected from steel with good corrosion resistance to extend the service life of the energy storage device. The battery bracket in the energy storage device is effectively connected to the bottom cross beam 400 and the bottom side beam 600, which further improves the stability of the entire system and ensures the safety of the battery during transportation.

[0073] Specifically, in some embodiments, the bottom cross beam 400 is made of a square material with a thickness between 5mm and 8mm, for example, the thickness of the bottom cross beam 400 is 5mm, 6mm, 7mm, and 8mm; the width of the bottom cross beam 400 is set between 110mm and 150mm, for example, its width is 110mm, 120mm, 130mm, 140mm, and 150mm, and its length is also within the range of 110mm to 150mm, for example, its width is 110mm, 120mm, 130mm, 140mm, and 150mm. As a preferred embodiment, the length, width, and thickness of the bottom cross beam 400 are 130mm, 130mm, and 6mm, respectively. Selecting such size specifications can ensure that the bottom cross beam 400 has sufficient strength to support the upper battery bracket and the weight it carries, while maintaining reasonable cost-effectiveness. In some embodiments, the bottom side beam 600 uses H-shaped steel as the main material, the width of the H-shaped steel is between 180mm and 220mm, and the height is also within this range. For example, the width and / or height of the H-shaped steel is 180mm, 190mm, 200mm, 210mm, 220mm, the thickness of the flange of the H-shaped steel is 7mm to 9mm, for example, the thickness of the flange is 7mm, 8mm, 9mm, and the thickness of the web of the H-shaped steel is 11mm to 13mm, for example, the thickness of the web is 11mm, 12mm, 13mm. As a preferred embodiment, the width and height of the H-shaped steel are both set to 200mm, the thickness of the flange is 8mm, and the thickness of the web is 12mm. By using this H-shaped steel with specific dimensional parameters, excellent bending resistance and stability can be provided, which is crucial to ensuring the safety of the entire energy storage device.

[0074] The bottom cross beam 400 and the bottom side beam 600 work together to form a stable basic platform to carry the battery bracket described above. Their design fully considers the load requirements in actual application scenarios, ensuring that good structural integrity and safety can be maintained even when fully loaded. In addition, by reasonably selecting materials and designing dimensions, the goal of lightweighting the overall structure is also achieved, which helps to reduce transportation costs.

[0075] It is understood that in some embodiments, the bottom cross beam 400 and the bottom side beam 600 in the energy storage device can be further optimized. For example, in addition to using ordinary materials such as hot-rolled steel plates, carbon steel, wood, etc., the bottom cross beam 400 can also consider using other types of high-strength steel or alloy materials, which may have better mechanical properties, such as higher yield strength and better corrosion resistance. For the selection of H-shaped steel, different grades of steel can also be explored, such as low-alloy high-strength steel, so that the dead weight can be reduced without sacrificing structural strength, thereby improving loading efficiency. In addition, regarding the connection method between the bottom cross beam 400 and the bottom side beam 600, in addition to the traditional welding process, bolt connection or other forms of detachable connection methods can also be used, which is not only convenient for installation and maintenance, but also more convenient and quick when damaged parts need to be replaced. Furthermore, considering that the energy storage device may encounter various complex environmental conditions, in terms of surface treatment, the bottom cross beam 400 and the bottom side beam 600 can be treated with a special anti-corrosion coating to extend the service life while reducing the maintenance frequency. Finally, in order to enhance the overall earthquake resistance of the energy storage device, additional reinforcement measures may be provided between the bottom cross beam 400 and the bottom side beam 600, such as adding diagonal braces or transverse tie rods, so as to further enhance the stability of the entire structural system.

[0076] like Figure 1 , 2 As shown, the chassis of the energy storage battery storage device, in addition to meeting some requirements of the standard energy storage device, the bottom cross beam 400 in contact with the column 110 group 100 adopts a square tube with a size of 130 mm wide by 130 mm high and a wall thickness of 6 mm; the bottom side beam 600 uses an H-shaped steel with a size of 200 mm wide by 200 mm high, a flange thickness of 8 mm, and a web thickness of 12 mm, or other steel with equivalent performance. Such a design ensures the reliability of the strength and rigidity of the chassis. In addition, the top side beam 700 uses a square tube with a size of 100 mm wide by 150 mm high and a wall thickness of 8 mm. The columns 110 of the front and rear walls are made of square tubes with a size of 100 mm wide by 150 mm high and a wall thickness of 8 mm. The base frame, front wall, rear wall, and side wall are welded to form a basic skeleton. Then the top crossbeam 500 of the energy storage device is welded, using No. 8 channel steel. This design has the characteristics of occupying less height space and high strength. Finally, the battery bracket is installed.

[0077] like Figures 1 to 3 As shown, the door frame column 110 and the square tube 120 are square tubes with a size of 50 mm x 100 mm and a wall thickness of 6 mm. From front to back, the battery bracket is arranged in sequence with a column 110 with a size of 80 mm wide x 120 mm high and a wall thickness of 4 mm, a double column 110 formed by two second columns 110 arranged side by side with a size of 100 mm wide x 120 mm high and a wall thickness of 4 mm, and another column 110 with a size of 80 mm wide x 120 mm high and a wall thickness of 4 mm. This structure is repeated in 6 groups from left to right, and a 6 mm thick circular reinforcement beam 810 or an 8 mm thick X-shaped reinforcement beam 810 is added at each gap as a shock absorbing structure 800. Subsequently, refer to Figure 4 , add a crossbeam 200 along the length direction at the waist of the battery support, and finally add a battery pack plate 900. In order to meet the high seismic grade requirements of IEEE693, the thickness of the battery pack plate 900 must be at least 4 mm. The fixing point 920 between the battery pack plate 900 and the column 110 is achieved by bolt connection or welding. Figure 1 and Figure 2 As shown, the single-cluster battery cladding plate 900 has three fixing points, namely fixing point 910 and fixing point 920 , among which fixing point 920 is indispensable.

[0078] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
