[0013] Furthermore, the various features described below can be combined in the embodiments of the present utility model, as long as they do not conflict with each other.

[0014] The following is an exemplary embodiment of the present utility model in conjunction with the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 to Fig. 8 described.

[0015] According to one embodiment of the present utility model, an insulating bracket is provided in one aspect, wherein a battery assembly 1 and a base 3 are provided at each end along the vertical direction; and the insulating bracket comprises the following: two connecting surfaces 21, wherein the two connecting surfaces 21 are spaced apart from each other and arranged parallel along the vertical direction; wherein the two connecting surfaces 21 are designed to be connected to the battery assembly 1 and the base 3 respectively via bolts 5; a connecting rib 26 which is connected between the two connecting surfaces 21, wherein the plane of the connecting rib 26 is simultaneously perpendicular to the two connecting surfaces 21; wherein the thickness of the connecting rib 26 along the width direction is less than the width of the connecting surface 21 along the width direction; several lamella sections 24 which are provided on the connecting rib 26 and extend along the width direction, wherein several lamella sections 24 are spaced apart along the height direction; the width of the lamella section 24 located in the middle along the height direction is greater than the width of the lamella section 24 located at both ends, wherein the height direction is perpendicular to the width direction.

[0016] The insulating support 2 of this embodiment is supported vertically between the battery assembly 1 and the base 3. Since both the battery assembly 1 and the base 3 are conductive structures, the battery assembly 1 can, in particular, comprise a battery rack and several battery groups arranged on the battery rack, and the base 3 serves as the base of the entire energy storage frame and can support several battery assemblies 1 simultaneously. The insulating support 2 is able to meet the design requirements with a floating ground connection for the battery and to perform an insulating function.

[0017] In this embodiment, the insulating bracket is “ The insulating bracket is shaped in a "-shape and has parallel connecting surfaces 21 at both ends along the vertical direction, wherein the connecting surfaces 21 in particular comprise a first connecting surface 211 and a second connecting surface 212 and the two connecting surfaces 21 are connected to each other via connecting rib 26. In particular, 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.

[0018] By forming a first connecting surface 211 and a second connecting surface 212 at both ends of the insulating bracket 2 along the vertical direction, the contact area between the insulating bracket 2 and the battery assembly 1 and the base 3 is increased, thereby ensuring stability during installation and facilitating connection and fastening. Specifically, the two connecting surfaces 21 are each connected to the battery assembly 1 and the base 3 via bolts 5.

[0019] However, since the insulating bracket “ Although the connecting rib 26, which is arranged in the middle position of the height direction, is designed in a "-shaped manner, it does meet the height requirements of the battery assembly 1, but due to its small thickness it represents a weak point in the strength of the entire insulating support structure, so that at an unsuitable force angle it bends easily and the bending deformation is further increased by the gravity of the battery assembly 1, which can ultimately lead to the breaking of the connecting rib 26 and thus to a collapse.

[0020] In this embodiment, the lamella section 24 is in the middle position of the “ "-shaped structure of the insulation support provided along the vertical direction, thereby improving the structural strength of the connecting rib 26, reducing the weak points in the structural strength of the entire insulation support and reducing the possibility of bending and deformation of the connecting rib 26.

[0021] Since the connecting surface 21 is connected to the battery assembly 1 and the base 3 via bolts 5, in this embodiment, to ensure that the bolts 5 can easily penetrate the bolt holes of the connecting surface 21 and to avoid obstruction of the lamellar section 24 during the installation of the bolts 5, the width of the lamellar section 24 in the middle area along the vertical direction is greater than the width of the lamellar sections 24 at both ends, so that the lamellar sections 24 at both ends can give way along the vertical direction and easy insertion of the bolts 5 into the bolt holes of the connecting surface 21 is ensured.

[0022] Since the insulating bracket is also “ Since the lamella section 24 is shaped in a "-shape", the risk of bending increases the closer it is to the central position of the connecting rib 26 along the vertical direction. Therefore, to meet the structural strength requirements and reduce the weight of the entire insulating bracket 2, the width of the lamella section 24 at both ends along the vertical direction can be correspondingly smaller than the width of the lamella section 24 in the central position along the vertical direction.

[0023] It should be noted that the width of the lamella section 24 is based on the in Fig. 3 and Fig. 4 shows the direction of width and the direction of width of the lamella section 24 runs perpendicular to the direction of height.

[0024] The insulating support 2 of this embodiment also has an insulating function, and in related technologies, insulating plates, insulating mats, insulating columns, etc., are frequently used to insulate the base and battery assembly. These insulating structures can meet the insulation requirements of medium- and low-voltage energy storage devices. However, due to insufficient creepage distances and other reasons, the insulation level and dielectric strength requirements of these insulating structures cannot meet the high-voltage insulation requirements of 35 kV. The 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. Fig. 7 is the path marked by the thick black line in this embodiment the creepage distance 4 of the insulating bracket 2.

[0025] In this embodiment, the insulating bracket is in the middle position of the “ The "-shaped structure is provided with a lamellar section 24 along its vertical direction, such that the insulating support has a sawtooth structure in its lateral direction, thereby increasing the creepage distance of the insulating support 2. This improves the insulation performance and ensures the insulating effect between the base 3 and the battery assembly 1, better meeting the high-voltage insulation requirements of 35 kV. In some embodiments, the width of the lamellar section 24 located in the middle along the vertical direction is D1, and the width of the lamellar section 24 located at both ends is D2, provided that the following condition is met: 2 mm ≤ D1-D2 ≤ 80 mm.

[0026] Limiting the lower boundary of D1-D2 prevents the width of the lamella section 24 from being too small at both ends along the vertical direction, thus ensuring that the structural strength does not meet the requirements. Simultaneously, it prevents the width of the lamella section 24 from being too large in the middle position along the vertical direction, which would lead to material waste. Limiting the upper boundary of D1-D2 prevents insufficient installation space for the bolts 5 and ensures that the lamella sections 24 provide sufficient space at both ends along the vertical direction for the installation of the bolts 5, thus ensuring that the bolts 5 can easily penetrate the bolt holes of the connecting surface 21.

[0027] In some embodiments, with reference to Fig. 7 the shortest distance between the lamella section 24 lying at one end along the vertical direction and the adjacent connecting surface 21 H2, wherein the following condition is met: 40 mm ≤ H2 ≤ 70 mm.

[0028] Limiting the lower boundary of H2 ensures sufficient space for fastening the bolts 5, allowing them to easily penetrate the bolt holes of the connecting surface 21. Limiting the upper boundary of H2 also prevents an excessive gap between the lamella section 24 at one end and the adjacent connecting surface 21, which could lead to insufficient structural strength. Furthermore, even after complying with the minimum creepage distance, additional material consumption and space loss are avoided.

[0029] In some embodiments, the connecting surface 21, which connects the insulating bracket and the battery assembly 1, is defined as the reference surface, and if the projection of the bolt 5 on the reference surface and the projection of the lamella section 24 on the reference surface partially overlap, the following condition is met: 2 mm ≤D1-D2≤ 80 mm.

[0030] If the projection of bolt 5 on the reference plane and the projection of lamella section 24 on the reference plane partially overlap, the fastening force on the connecting surface 21 is stronger, so that D2 does not need to be set too long to avoid waste.

[0031] In some embodiments, the connecting surface 21, which connects the insulating bracket and the battery assembly 1, is defined as the reference surface, and if the projection of the bolt 5 on the reference surface and the projection of the lamella section 24 on the reference surface do not overlap, the following condition is met: 20 mm ≤D1-D2≤ 65 mm.

[0032] If the projection of bolt 5 on the reference surface and the projection of lamellar section 24 on the reference surface do not overlap, the fastening force on the connecting surface 21 is weaker, so the length of D2 must be increased to increase the strength of the insulating bracket.

[0033] In some embodiments the distance between adjacent lamella sections (24) is H1, and the following condition is met: 6 mm ≤ H1 ≤ 12 mm.

[0034] By limiting the upper limit of the distance H1 between adjacent lamella sections 24, insufficient structural strength due to an excessively large distance between adjacent lamella sections 24 can be avoided. At the same time, increased material consumption and wasted space can be avoided after reaching the basic creep distance. By limiting the lower limit of the distance H1 between the adjacent lamella sections 24, a situation in which the creep distance is insufficient can be avoided.

[0035] In some embodiments, reference is made to Fig. 7 the parallel connecting surfaces 21 are connected via connecting ribs 26 and the lamella sections 24 are arranged symmetrically to the connecting rib 26 with the connecting rib 26 as the central axis, wherein the following condition is met: 20 mm ≤D1-D2≤ 65 mm.

[0036] With the connecting rib 26 as its central axis, the lamella sections 24 are arranged symmetrically to the connecting rib 26. Sufficient spacing must be maintained between adjacent lamella sections 24 along the vertical direction to meet the creepage distance requirements, while simultaneously preventing insufficient structural strength due to excessive spacing between adjacent lamella sections 24. Accordingly, the range of values ​​D1-D2 can be narrowed.

[0037] In some embodiments, reference is made to Fig. 8 the parallel connecting surfaces 21 are connected via connecting ribs 26 and the lamella sections 24 are arranged with the connecting rib 26 as the central axis offset relative to the connecting rib 26, whereby the following condition is met: 2 mm ≤D1-D2≤ 80 mm.

[0038] If the lamella sections 24 are arranged offset relative to the connecting rib 26 as their central axis, then along the width direction, as shown in Fig. As shown in Figure 8, for example, at the lamella section 24 on the left side of the connecting rib 26, the distance between adjacent lamella sections 24 along the vertical direction is sufficient to meet the creepage distance requirements. Similarly, the lamella section 24 on the right side of the connecting rib 26 can also meet the creepage distance requirements. At this point, the distance along the vertical direction between the lamella section 24 on the left side of the connecting rib 26 and the lamella section 24 on the right side of the nearest connecting rib 26 can be further reduced.

[0039] In some embodiments, the parallel connecting surfaces 21 are connected via connecting ribs 26 and the thickness of the connecting rib 26 is F along the width direction, where the following condition is met: 6 mm ≤F ≤ 15 mm.

[0040] By limiting the lower limit of the thickness F of the connecting rib 26, insufficient structural strength caused by an excessively thin connecting rib 26 can be avoided, the structural strength of the connecting rib 26 is ensured, and the weak points in the structural strength of the entire insulating bracket are reduced. By limiting the upper limit of the thickness F of the connecting rib 26, excessive weight of the insulating bracket 2 can be avoided, material waste can be prevented, while simultaneously ensuring the structural strength of the connecting rib 26.

[0041] In some additional embodiments, the insulating bracket has several width-oriented recesses 25 in a cross-section perpendicular to the longitudinal direction, wherein the several width-oriented recesses 25 are spaced apart along the height direction; the insulating bracket has several longitudinal-oriented recesses 23 in a cross-section perpendicular to the width direction, wherein the several longitudinal-oriented recesses 23 are spaced apart along the height direction;

[0042] The altitude, longitude, and latitude directions are perpendicular to each other.

[0043] In this embodiment, the insulating bracket has several width-oriented recesses 25 in a cross-section perpendicular to the longitudinal direction, wherein the several width-oriented recesses 25 are spaced apart along the height direction; and the insulating bracket has several longitudinal-oriented recesses 23 in a cross-section perpendicular to the width direction, wherein the several longitudinal-oriented recesses 23 are spaced apart along the height direction; so that a sawtooth structure is formed in both the longitudinal and width directions of the insulating bracket, thereby increasing the creepage distance of the insulating bracket 2 in several directions.

[0044] By forming a sawtooth structure in the longitudinal and transverse directions of the insulating bracket, the creepage distance of the insulating bracket 2 is increased, the insulation performance is improved and the insulating effect between the battery assembly 1 and the base 3 is ensured, so that the high voltage insulation requirements of 35 kV are better met.

[0045] In this embodiment, the insulating bracket 2 is made of an insulating material, for example, plastic. By forming a sawtooth structure in both the longitudinal and lateral directions of the insulating bracket, the structural strength of the insulating bracket 2 can be improved, thus ensuring its support stability.

[0046] In some embodiments, with reference to Fig. 5 the insulating bracket The following: several lamella sections 24, wherein the several lamella sections 24 are spaced apart along the vertical direction; Connecting ribs 26 that connect the adjacent lamella sections 24; wherein width-oriented recesses 25 are formed in the intervals between adjacent lamella sections 24.

[0047] In this embodiment, the lamella section 24 extends in a plane perpendicular to the vertical direction, wherein the lengths of the several lamella sections 24 along the longitudinal direction can be equal or unequal and the widths of the several lamella sections 24 along the lateral direction can be equal or unequal.

[0048] The connecting ribs 26 extend along the vertical direction to connect adjacent lamella sections 24, so that the insulating bracket forms an integrated structure.

[0049] In this embodiment, the connecting rib 26 is positioned in the central location of the lamella section 24 along its width, such that the lamella section 24 is evenly distributed on both sides of the connecting rib 26 along its width. The insulating bracket 2 forms a centrally symmetrical structure along its width, thereby improving the structural stability of the insulating bracket 2 and ensuring its supportive effect.

[0050] In some embodiments, with reference to Fig. 6 at least one lamella section 24 is shorter along the longitudinal direction than the other lamella sections 24 in order to form a longitudinally oriented recess 23; and / or at least a part of the connecting rib 26 is recessed along the longitudinal direction in order to form a longitudinally oriented recess 23.

[0051] By forming the longitudinally oriented recess 23, the creepage distance of the insulating bracket 2 can be increased and the insulating effect can thereby be ensured.

[0052] In some embodiments, reference is made to Fig. 5 the width-oriented recesses 25 are provided along the width direction on both sides of the insulating bracket; and / or the length-oriented recesses 23 are provided along the length direction on both sides of the insulating bracket.

[0053] Furthermore, the width-oriented recesses 25 are provided along the width direction on both sides of the insulating bracket; and / or the length-oriented recesses 23 are provided along the length direction on both sides of the insulating bracket. This subjects the insulating bracket 2 to uniform forces and makes the structure more stable.

[0054] The first connecting surface 211 and the second connecting surface 212 can be formed as part of the lamella section 24 and also serve the role of insulation and increasing the creepage distance. Furthermore, the dimensions of the first connecting surface 211 and the second connecting surface 212 along the longitudinal direction are no smaller than the dimensions of the lamella section 24 along the longitudinal direction, thus 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 lengths of the first connecting surface 211 and the second connecting surface 212 along the longitudinal direction are no smaller than the lengths of the other lamella sections 24 along the longitudinal direction.

[0055] According to one embodiment of the present utility model, in another aspect an energy storage frame is provided which comprises: a battery assembly 1 and a base 3; and an insulating support 2 mentioned above, which is arranged along the vertical direction between the battery assembly 1 and the base 3; where the number of battery assemblies is 1 X and the number of insulating brackets is 2 N·X, where each battery assembly is assigned 1 N insulating brackets 2; where N and X are each positive integers; where adjacent insulating brackets 2 are not arranged continuously.

[0056] The insulating support is arranged along the vertical direction between the battery assembly 1 and the base 3. In this embodiment, the battery assembly 1 and the base 3 can each be the battery assembly 1 and the base 3, respectively, wherein the battery assembly 1 is filled with batteries and the base 3 is designed as the base of the entire energy storage frame, and the base 3 can support several battery assemblies 1 simultaneously.

[0057] The formation of a sawtooth structure in the longitudinal and transverse directions of the insulating bracket increases the creepage distance of the insulating bracket 2, improves the insulation performance, and ensures the insulating effect between the battery assembly 1 and the base 3, thus better meeting the high-voltage insulation requirements of 35 kV. Furthermore, the sawtooth structure can also improve the structural strength of the insulating bracket 2 and ensure its load-bearing stability on the battery assembly 1.

[0058] By assigning N insulating supports 2 to each battery assembly 1, the insulating supports 2 can achieve multi-point support for the battery assembly 1, thereby ensuring the connection strength, reducing the effects of the continuity of the insulating support 2 and effectively ensuring the creepage distance.

[0059] The insulating brackets 2 are connected on both sides along the vertical direction to the battery assembly 1 and the base 3 by means of bolts and nuts.

[0060] In some embodiments, when X ≥ 2, adjacent battery assemblies 1 are connected via bolts.

[0061] When multiple battery assemblies 1 are connected, the fastening strength can be increased by connecting adjacent battery assemblies 1 with bolts, thus ensuring stability during transport. Furthermore, adjacent insulating brackets 2 are not arranged continuously, which does not impair the insulation performance.

[0062] Obviously, the above embodiments are merely examples for clarification and are not intended to limit the embodiments. Although the embodiments of the present utility model are described in conjunction with the figures, a person skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations all fall within the scope of protection defined by the appended claims.
