At the same time, since the connecting surface is connected to the battery assembly and the base via bolts, in order to ensure that the bolts can smoothly penetrate into the screw holes of the connecting surface and avoid interference with the installation of the bolts by the fin portion, this embodiment makes the width of the fin portion located in the middle along the height direction greater than the width of the fin portion located at both ends, so that the fin portions located at both ends along the height direction can give way to ensure that the bolts can smoothly penetrate into the screw holes of the connecting surface.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] Combine the following Figures 1 to 8 , describing an embodiment of the present invention.

[0033] According to an embodiment of the present invention, on the one hand, an insulating bracket is provided, and a battery assembly 1 and a base 3 are respectively arranged at both ends along the height direction; the insulating bracket includes:

[0034] Two connecting surfaces 21, the two connecting surfaces 21 are spaced apart and arranged in parallel along the height direction; the two connecting surfaces 21 are suitable for being connected to the battery assembly 1 and the base 3 respectively via bolts 5;

[0035] The connecting rib 26 is connected between the two connecting surfaces 21, and the plane where the connecting rib 26 is located is perpendicular to the two connecting surfaces 21 at the same time; the thickness of the connecting rib 26 along the width direction is smaller than the width of the connecting surface 21 along the width direction;

[0036] Multiple fin portions 24 are arranged on the connecting rib 26 and extend along the width direction. Multiple fin portions 24 are arranged at intervals along the height direction. The width of the fin portion 24 located in the middle along the height direction is greater than the width of the fin portion 24 located at both ends, wherein the height direction is perpendicular to the width direction.

[0037] The insulating bracket 2 of this embodiment is supported between the battery assembly 1 and the base 3 along the height direction. Since the battery assembly 1 and the base 3 are both conductive structures, the battery assembly 1 may specifically include a battery rack and multiple groups of batteries arranged on the battery rack. The base 3 serves as the base of the entire energy storage frame, and the base 3 can simultaneously support multiple battery assemblies 1. The insulating bracket 2 can meet the requirements of the battery floating design and play an insulating role.

[0038] In this embodiment, the insulating bracket is constructed in an "I" shape, and parallel connecting surfaces 21 are respectively provided at both ends of the insulating bracket in the height direction. The connecting surfaces 21 specifically include a first connecting surface 211 and a second connecting surface 212, and the two connecting surfaces 21 are connected via a connecting rib 26. Specifically, one side of the first connecting surface 211 is connected to the connecting rib 26, and the other side is fixedly connected to the battery assembly 1; one side of the second connecting surface 212 is connected to the connecting rib 26, and the other side is fixedly connected to the base 3.

[0039] By forming a first connection surface 211 and a second connection surface 212 at both ends of the insulating bracket 2 in the height direction, the contact area between the insulating bracket 2 and the battery assembly 1 and the base 3 is increased, ensuring stability during installation and facilitating connection and fixing. Specifically, the connection surface 21 is connected to the battery assembly 1 and the base 3 via bolts 5.

[0040] However, since the insulating bracket is constructed in an "I" shape, the connecting rib 26 located in the middle of the height direction meets the height requirement of the battery assembly 1, but the connecting rib 26, due to its thin thickness, will become a weak link in the strength of the entire insulating bracket structure. It is easy to bend when the force angle is not appropriate, and then the bending deformation is further aggravated under the action of gravity of the battery assembly 1, which may eventually cause the connecting rib 26 to break and cause a collapse accident.

[0041] In this embodiment, a fin portion 24 is provided at the middle position of the "I"-shaped structure of the insulating bracket in the height direction, thereby improving the structural strength of the connecting rib 26, reducing the weak links in the structural strength of the entire insulating bracket, and reducing the possibility of bending and deformation of the connecting rib 26.

[0042] At the same time, since the connecting surface 21 is respectively connected to the battery assembly 1 and the base 3 via the bolts 5, in order to ensure that the bolts 5 can smoothly penetrate into the screw holes of the connecting surface 21 and avoid the fin portion 24 from interfering with the installation of the bolts 5, this embodiment makes the width of the fin portion 24 located in the middle along the height direction greater than the width of the fin portion 24 located at both ends, so that the fin portions 24 located at both ends along the height direction can make way, thereby ensuring that the bolts 5 can smoothly penetrate into the screw holes of the connecting surface 21.

[0043] In addition, since the insulating bracket is constructed as an "I"-shaped bracket, the closer to the middle of the connecting rib 26 along the height direction, the greater the risk of bending. Therefore, under the premise of meeting the structural strength requirements, in order to reduce the weight of the entire insulating bracket 2, the width of the fin portion 24 at both ends along the height direction can be appropriately smaller than the width of the fin portion 24 located in the middle along the height direction.

[0044] It should be noted that the width of the fin portion 24 refers to the width of the fin portion 24. Figure 3 , Figure 4 In the width direction shown in FIG. 1 , the width direction of the fin portion 24 is perpendicular to the height direction.

[0045] The insulating bracket 2 of this embodiment also plays an insulating role. In the related art, insulating plates, insulating mats, insulating pillars, etc. are often used to isolate the base from the battery assembly. These insulating structures can meet the insulation requirements of medium and low voltage energy storage equipment. However, due to insufficient creepage distance and other reasons, the insulation level and withstand voltage requirements of these insulating structures cannot meet the high-voltage insulation requirements of 35KV.

[0046] Creepage distance is the shortest path between two conductive parts or between a conductive part and the protective interface of the equipment measured along the insulating surface. Figure 7 As shown, the path indicated by the thick black line in the figure is the creepage distance 4 of the insulating bracket 2 in this embodiment.

[0047] In this embodiment, the insulating bracket is provided with a fin portion 24 in the middle of the "I"-shaped structure in the height direction, so that the insulating bracket forms a zigzag structure in the width direction, thereby increasing the creepage distance of the insulating bracket 2. The insulation performance is improved, and the insulation effect between the base 3 and the battery assembly 1 is ensured, so as to better meet the 35KV high-voltage insulation requirements.

[0048] In some embodiments, the width of the fin portion 24 located in the middle along the height direction is D1, and the width of the fin portion 24 located at both ends along the height direction is D2, satisfying: 2mm≤D1-D2≤80mm.

[0049] By limiting the lower limit of D1-D2, it is possible to prevent the width of the fin portion 24 at both ends along the height direction from being too narrow, thereby preventing the structural strength from failing to meet the requirements, and at the same time, preventing the width of the fin portion 24 at the middle along the height direction from being too large, thereby preventing material waste. By limiting the upper limit of D1-D2, it is possible to prevent insufficient installation space reserved for the bolt 5, ensure that the fin portion 24 at both ends along the height direction can make way for the installation space of the bolt 5, and ensure that the bolt 5 can smoothly penetrate into the screw hole of the connection surface 21.

[0050] In some embodiments, in combination Figure 7 As shown, the shortest distance between the fin portion 24 at one end and the adjacent connecting surface 21 along the height direction is H2, which satisfies: 40 mm ≤ H2 ≤ 70 mm.

[0051] By limiting the lower limit of H2, sufficient space can be reserved for the fixing of the bolt 5, ensuring that the bolt 5 can smoothly penetrate into the screw hole of the connection surface 21. At the same time, limiting the upper limit of H2 can avoid the distance between the fin portion 24 at one end and the adjacent connection surface 21 being too large in the height direction, thereby preventing the structural strength from being insufficient, and avoiding the consumption of more materials and wasting space after satisfying the basic creepage distance.

[0052] In some embodiments, the connection surface 21 where the insulating bracket and the battery assembly 1 are connected is defined as a reference plane, and when the projection of the bolt 5 on the reference plane partially overlaps with the projection of the fin portion 24 on the reference plane, the following is satisfied: 2mm≤D1-D2≤80mm.

[0053] When the projection of the bolt 5 on the reference plane partially overlaps with the projection of the fin portion 24 on the reference plane, the fastening force on the connection surface 21 is relatively strong, so D2 does not need to be set too long to avoid waste.

[0054] In some embodiments, the connection surface 21 where the insulating bracket and the battery assembly 1 are connected is defined as a reference plane, and when the projection of the bolt 5 on the reference plane and the projection of the fin portion 24 on the reference plane do not overlap, the following is satisfied: 20mm≤D1-D2≤65mm.

[0055] When the projection of the bolt 5 on the reference plane does not coincide with the projection of the fin portion 24 on the reference plane, the fastening force on the connection surface 21 is weak, and therefore the length of D2 needs to be increased to increase the strength of the insulating bracket.

[0056] In some embodiments, the distance between adjacent fin portions 24 is H1, satisfying: 6 mm ≤ H1 ≤ 12 mm.

[0057] By limiting the upper limit of the spacing H1 between adjacent fin portions 24, insufficient structural strength caused by excessive spacing between adjacent fin portions 24 can be avoided, and more materials should be avoided to avoid wasting space after the basic creepage distance is met. By limiting the lower limit of the spacing H1 between adjacent fin portions 24, insufficient creepage distance can be avoided.

[0058] In some embodiments, in combination Figure 7 As shown, the mutually parallel connecting surfaces 21 are connected via connecting ribs 26, with the connecting ribs 26 as the central axis, and the fin portions 24 are symmetrically arranged relative to the connecting ribs 26, satisfying: 20mm≤D1-D2≤65mm.

[0059] With the connecting rib 26 as the central axis, the fin portion 24 is symmetrically arranged relative to the connecting rib 26. At this time, the adjacent fin portions 24 along the height direction need to ensure sufficient spacing to meet the creepage distance requirement, while avoiding insufficient structural strength caused by excessive spacing between adjacent fin portions 24. Correspondingly, the value range of D1-D2 can be narrowed.

[0060] In some embodiments, in combination Figure 8 As shown, the parallel connecting surfaces 21 are connected via connecting ribs 26, with the connecting ribs 26 as the central axis, and the fin portion 24 is staggered relative to the connecting ribs 26 to meet the following conditions: 2mm≤D1-D2≤80mm.

[0061] When the fin portion 24 is staggered relative to the connecting rib 26 with the connecting rib 26 as the central axis, the fin portion 24 is staggered relative to the connecting rib 26 along the width direction. Figure 8 Taking the fin portion 24 on the left side of the connecting rib 26 as an example, since the spacing between the adjacent fin portions 24 in the height direction is sufficient to meet the creepage distance requirement, similarly, the fin portion 24 located on the right side of the connecting rib 26 can also meet the creepage distance requirement. At this time, along the height direction, the spacing between the fin portion 24 on the left side of the connecting rib 26 and the fin portion 24 on the right side of the closest connecting rib 26 can be further shortened.

[0062] In some embodiments, the parallel connecting surfaces 21 are connected via connecting ribs 26 . Along the width direction, the thickness of the connecting ribs 26 is F, satisfying: 6 mm ≤ F ≤ 15 mm.

[0063] By limiting the lower limit of the thickness F of the connecting rib 26, insufficient structural strength caused by too thin thickness of the connecting rib 26 can be avoided, the structural strength of the connecting rib 26 can be ensured, and the weak link of the structural strength of the entire insulating support can be reduced. By limiting the upper limit of the thickness F of the connecting rib 26, the weight of the insulating support 2 can be avoided to be too large on the basis of ensuring the structural strength of the connecting rib 26, thereby preventing material waste.

[0064] In some additional embodiments, the insulating bracket is formed with a plurality of widthwise notches 25 in a cross section perpendicular to the lengthwise direction, and the plurality of widthwise notches 25 are spaced apart along the height direction;

[0065] The insulating bracket is formed with a plurality of longitudinal notches 23 in a cross section perpendicular to the width direction, and the plurality of longitudinal notches 23 are spaced apart along the height direction;

[0066] Among them, the height direction, the length direction and the width direction are perpendicular to each other.

[0067] In this embodiment, the insulating bracket is provided with a plurality of widthwise notches 25 in a cross section perpendicular to the length direction, and the plurality of widthwise notches 25 are spaced apart along the height direction; and the insulating bracket is provided with a plurality of lengthwise notches 23 in a cross section perpendicular to the width direction, and the plurality of lengthwise notches 23 are spaced apart along the height direction; thereby forming a serrated structure in both the length direction and the width direction of the insulating bracket, thereby increasing the creepage distance of the insulating bracket 2 in multiple directions.

[0068] By forming a serrated structure on the insulating bracket in both the length and width directions, the creepage distance of the insulating bracket 2 is increased, the insulation performance is improved, and the insulation effect between the battery assembly 1 and the base 3 is ensured, so as to better meet the high-voltage insulation requirements of 35KV.

[0069] In this embodiment, the insulating bracket 2 is made of an insulating material, such as plastic. By forming a serrated structure in both the length and width directions of the insulating bracket, the structural strength of the insulating bracket 2 can be improved and the supporting stability of the insulating bracket 2 can be ensured.

[0070] In some embodiments, in combination Figure 5 As shown, the insulating bracket includes:

[0071] A plurality of fin portions 24, wherein the plurality of fin portions 24 are arranged at intervals along a height direction;

[0072] A connecting rib 26 connected between adjacent fin portions 24;

[0073] The interval area between adjacent fin portions 24 forms a widthwise notch portion 25 .

[0074] In this embodiment, the fin portion 24 extends in a plane perpendicular to the height direction, and the lengths of the plurality of fin portions 24 along the length direction may be equal or unequal, and the widths of the plurality of fin portions 24 along the width direction may be equal or unequal.

[0075] The connecting ribs 26 extend in the height direction to connect adjacent fin portions 24 so that the insulating bracket forms an integrated structure.

[0076] In this embodiment, the connecting rib 26 is arranged in the middle of the fin portion 24 along the width direction, so that the fin portion 24 is evenly distributed on both sides of the connecting rib 26 along the width direction. The insulating bracket 2 forms a centrally symmetrical structure along the width direction, thereby improving the structural stability of the insulating bracket 2 and ensuring the supporting effect of the insulating bracket 2.

[0077] In some embodiments, in combination Figure 6 As shown, at least one fin portion 24 is shorter than other fin portions 24 along the length direction to form a longitudinal notch portion 23;

[0078] And / or, at least a portion of the connecting rib 26 is recessed along the length direction to form a longitudinal notch portion 23 .

[0079] By forming the longitudinal notch portion 23 , the creepage distance of the insulating bracket 2 can be increased, thereby ensuring the insulating effect.

[0080] In some embodiments, in combination Figure 5 As shown, along the width direction, the widthwise notch portions 25 are arranged on both sides of the insulating bracket; and / or, along the lengthwise notch portions 23 are arranged on both sides of the insulating bracket.

[0081] Furthermore, along the width direction, the widthwise notches 25 are symmetrically arranged on both sides of the insulating bracket, and along the lengthwise notches 23 are symmetrically arranged on both sides of the insulating bracket, so that the insulating bracket 2 is subjected to balanced forces and has a more stable structure.

[0082] The first connection surface 211 and the second connection surface 212 can be used as part of the fin portion 24, and also play the role of insulation and increasing the creepage distance. The dimensions of the first connection surface 211 and the second connection surface 212 along the width direction are not less than the dimensions of the other fin portions 24 along the width direction, thereby ensuring that the contact area with the battery assembly 1 and the base 3 is large enough to make the installation more stable. Similarly, the dimensions of the first connection surface 211 and the second connection surface 212 along the length direction are not less than the dimensions of the other fin portions 24 along the length direction.

[0083] According to an embodiment of the present invention, on the other hand, there is also provided an energy storage frame, comprising:

[0084] Battery assembly 1 and base 3;

[0085] and an insulating support 2 as described above, which is arranged between the battery assembly 1 and the base 3 in the height direction;

[0086] The number of battery assemblies 1 is X, the number of insulating brackets 2 is NX, and each battery assembly 1 corresponds to N insulating brackets 2; wherein N and X are both positive integers;

[0087] Adjacent insulating brackets 2 are arranged discontinuously.

[0088] The insulating bracket is arranged between the battery assembly 1 and the base 3 along the height direction. In this embodiment, the battery assembly 1 and the base 3 can be the battery assembly 1 and the base 3 respectively. The battery assembly 1 is full of batteries. The base 3 serves as the base of the entire energy storage frame. The base 3 can support multiple battery assemblies 1 at the same time.

[0089] By forming a sawtooth structure in both the length and width directions of the insulating bracket, the creepage distance of the insulating bracket 2 is increased, the insulation performance is improved, and the insulation effect between the battery assembly 1 and the base 3 is ensured, so as to better meet the 35KV high-voltage insulation requirements. In addition, the sawtooth structure can also improve the structural strength of the insulating bracket 2 and ensure the stability of the insulating bracket 2 supporting the battery assembly 1.

[0090] By making each battery assembly 1 correspond to N insulating brackets 2, the insulating brackets 2 can support the battery assembly 1 at multiple points, thereby ensuring the connection strength and reducing the influence of the continuity of the insulating brackets 2, thereby effectively ensuring the creepage distance.

[0091] Both sides of the insulating bracket 2 along the height direction are connected to the battery assembly 1 and the base 3 by means of bolts and nuts.

[0092] In some embodiments, when X≥2, adjacent battery assemblies 1 are connected via bolts.

[0093] When there are multiple battery assemblies 1, the fixing strength can be increased by connecting adjacent battery assemblies 1 with bolts to ensure stability during transportation. Adjacent insulating brackets 2 are still arranged discontinuously, which will not affect the insulation performance.

[0094] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
