[0026] Some embodiments of the present disclosure will be described in detail here, and examples thereof are shown in the accompanying drawings.

Various changes, modifications and equivalents of the methods, devices and / or systems described herein will become apparent after understanding the present disclosure.

[0027] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0028] See also Figure 1 , which representatively shows a schematic diagram of the structure of the insulating bracket 100 proposed in the present disclosure. In this exemplary embodiment, the insulating bracket 100 proposed in the present disclosure is described by taking the application to a vehicle-mounted power battery as an example. It is easy for those skilled in the art to understand that in order to apply the relevant design of the present disclosure to other types of battery devices, various modifications, additions, substitutions, deletions or other changes are made to the specific embodiments described below, and these changes are still within the scope of the principle of the insulating bracket 100 proposed in the present disclosure.

[0029] like Figure 1 As shown, in one embodiment of the present disclosure, the insulating bracket 100 provided in the present disclosure includes a bracket body 110. Figures 2 to 10 , Figure 2 , a schematic diagram of the decomposition of the insulating bracket 100 is representatively shown, in which the first sealing cover 131 and the second sealing cover 132 are disassembled from the bracket body 110; Figure 3 and Figure 4 The representative figures are shown in Figure 2 The schematic diagram of the structure of the partial structure at two different viewing angles shows the structure of the support body 110 and the heat-resistant layer 120 in detail; Figure 5 Representatively shown in Figure 3 A top view of the structure shown; Figure 6 The representative diagram shows the Figure 5 Schematic diagram of the cross section made by the straight line AA in; Figure 7 A representative example is shown in Figure 6 An enlarged schematic diagram of part B in FIG. Figure 8 A representative example is shown in Figure 6 An enlarged schematic diagram of part C in FIG. Fig. 9 , a schematic structural diagram of the insulating support 100 connected to the first main connecting bar 210 and the second main connecting bar 220 is representatively shown; Fig.10 and Fig.11 2 and 3 respectively show schematic diagrams of the process of connecting and assembling the insulating support 100 with the first main connecting bar 210 and the second main connecting bar 220. The structure, connection mode and functional relationship of the main components of the insulating support 100 proposed in the present disclosure will be described in detail below in conjunction with the above drawings.

[0030] like Figures 1 to 5 , Fig. 9 As shown, in one embodiment of the present disclosure, the insulating bracket 100 proposed in the present disclosure is used to be arranged in a battery box of a battery device. The bracket body 110 is connected to the battery box, and the bracket body 110 is made of an insulating material. The bracket body 110 has a first connection surface 1101 (for example, the top surface of the bracket body 110 shown in the figure), and the first connection surface 1101 has a first area 1102 and a second area 1103. Among them, the first area 1102 of the first connection surface 1101 is used to connect the first main connection row 210, and the second area 1103 is used to connect the second main connection row 220, and the polarity of the first main connection row 210 and the second main connection row 220 is opposite. On this basis, a retaining wall 111 is protruding from the first connection surface 1101, a part of the retaining wall 111 is located between the first area 1102 and the second area 1103, and another part of the retaining wall 111 is located at least one edge area of ​​the first connection surface 1101. Through the above design, the present disclosure can use the retaining wall 111 to increase the creepage distance, improve the insulation isolation effect between the first area 1102 and the second area 1103, and improve the insulation isolation effect between the connection position of the connection row and the edge area of ​​the bracket body 110, thereby avoiding insulation failure. Accordingly, when the arrangement of the first main connection row 210 and the second main connection row 220 on the insulating bracket 100 is relatively compact, or when the insulating bracket 100 is close to other charged structures in the battery device (such as single cells 410, etc.), the insulation failure problem can be avoided. Therefore, on the basis of improving the space utilization of the battery device, the safety of the battery device can be guaranteed.

[0031] like Figures 2 to 5 , Fig. 9 As shown, in one embodiment of the present disclosure, the retaining wall 111 can be arranged around the first area 1102 and the second area 1103, thereby forming a first accommodation space on the first area 1102 and a second accommodation space on the second area 1103. The first accommodation space is used to accommodate a part of the structure of the first main connection bar 210, and the second accommodation space is used to accommodate a part of the structure of the second main connection bar 220. Through the above design, the present disclosure can use the retaining wall 111 to be arranged around the first area 1102 and the second area 1103, and further improve the insulation effect of the connection between the first main connection bar 210, the second main connection bar 220 and the bracket body 110.

[0032] like Figures 1 to 5 , Fig. 9As shown, based on the design that the retaining wall 111 is arranged around the first area 1102 and the second area 1103, in one embodiment of the present disclosure, the retaining wall 111 may be provided with a first notch 1111 and a second notch 1112. The first notch 1111 is connected to the above-mentioned first accommodation space, and the first notch 1111 allows the first main connecting row 210 to extend out of the first accommodation space. The second notch 1112 is connected to the above-mentioned second accommodation space, and the second notch 1112 allows the second main connecting row 220 to extend out of the second accommodation space. On this basis, the directions of the first notch 1111 and the second notch 1112 may be different.

[0033] like Figures 1 to 5 , Fig. 9 As shown, in one embodiment of the present disclosure, the first notch 1111 and the second notch 1112 may be oriented in opposite directions. For example, the first notch 1111 and the second notch 1112 are oriented toward opposite sides of the direction D2 shown in the figure. Fig.12 and Fig.13 When the arrangement shown is installed on the longitudinal beam 310, the first notch 1111 and the second notch 1112 are respectively oriented to the opposite sides in the direction D4 shown in the figure, that is, respectively oriented to the two battery columns 400 on both sides of the longitudinal beam 310, so as to facilitate the first main connection row 210 (first sub-connection row 211) and the second main connection row 220 (third sub-connection row 221) respectively connected to the two battery columns 400 to be connected to the insulating bracket 100 via the two notches. Through the above design, the present disclosure utilizes the first notch 1111 and the second notch 1112 to facilitate the connection of the lead-out structure of the battery columns on both sides, reduce the bending of the connection row, reduce the difficulty of assembly, and simplify the complexity of the structure. On this basis, since the first notch 1111 and the second notch 1112 are oriented in different directions, the first main connection row 210 and the second main connection row 220 can be led out from different directions, further reducing the difficulty of assembly and improving the rationality of the structure. In some other embodiments of the present disclosure, when the retaining wall 111 is provided with a first notch 1111 and a second notch 1112 , the orientations of the first notch 1111 and the second notch 1112 may be the same, or the present embodiment is not limited thereto.

[0034] like Figures 2 to 5 , Fig. 9As shown, based on the design that the retaining wall 111 is arranged around the first region 1102 and the second region 1103, in an embodiment of the present disclosure, the first region 1102 and the second region 1103 may be arranged along a first direction (for example, the direction D1 shown in the accompanying drawings), and this first direction is parallel to the first connection surface 1101. On this basis, the first notch 1111 and the second notch 1112 may respectively face opposite sides in a second direction (for example, the direction D2 shown in the accompanying drawings), and this second direction is parallel to the first connection surface 1101 and perpendicular to the first direction. Through the above design, the present disclosure can achieve the "front-back" connection of the first main connection row 210 and the second main connection row 220 on the insulating bracket 100, and at the same time achieve the "left-right" lead-out of the first main connection row 210 and the second main connection row 220 from the insulating bracket 100, further ensuring the spaced arrangement in space of the lead-out parts of the first main connection row 210 and the second main connection row 220, and improving the insulation performance and structural rationality. In some other embodiments of the present disclosure, the first notch 1111 and the second notch 1112 may also respectively face opposite sides in the first direction, and are not limited to this embodiment.

[0035] As Figures 2 to 5 shown, based on the design that the retaining wall 111 is arranged around the first region 1102 and the second region 1103, in an embodiment of the present disclosure, on a reference plane parallel to the first connection surface 1101, the orthographic projection pattern of the retaining wall 111 may be approximately in an "S" shape. Through the above design, on the basis of realizing the surrounding arrangement of the retaining wall 111 and the structural design of the first notch 1111 and the second notch 1112, the present disclosure can further reduce the structural complexity of the retaining wall 111 and facilitate processing.

[0036] It should be noted that Figures 2 to 5 in the illustrated embodiment, the orthographic projection pattern of the retaining wall 111 being approximately in an "S" shape is taken as an example for illustration, that is, except for a part of the retaining wall 111 between the first region 1102 and the second region 1103, all or part (for example, the regions where the first notch 1111 and the second notch 1112 are provided) of the edge regions of the first connection surface 1101 are provided with the retaining wall 111. It should be understood that in various possible embodiments that conform to the design concept of the present disclosure, the retaining wall 111 in the edge region of the first connection surface 1101 may also be other structures. Accordingly, the overall orthographic projection pattern of all the retaining walls 111 protruding on the first connection surface 1101 may also be other shapes, such as a "ㄱ" shape, a "丄" shape, a "凵" shape, a "ㄣ" shape, an "H" shape, a "日" shape, etc., and is not limited to this embodiment.

[0037] As Figure 1 、 Figure 2 and Fig. 9As shown, in one embodiment of the present disclosure, the insulating bracket 100 proposed in the present disclosure may also include a first sealing cover 131, which is detachably connected to the retaining wall 111, and the first sealing cover 131 is specifically located above at least a portion of the first accommodating space. Through the above design, the present disclosure can use the first sealing cover 131 to shield at least a portion of the first accommodating space, further protecting the first main connection row 210 from impact and collision from above, and at the same time preventing dust and impurities from falling into the first accommodating space, thereby improving the connection reliability of the first main connection row 210. In addition, the first sealing cover 131 can also be made of insulating material to further improve the insulation effect, for example, Fig.11 As shown, when the first main connecting bar 210 has been connected to the insulating bracket 100 and the second main connecting bar 220 and the insulating bracket 100 need to be disassembled or connected and assembled, the first sealing cover 131 can be installed on the bracket body 110 to prevent the operator from contacting the first main connecting bar 210, further improving safety, and further facilitating the first main connecting bar 210 and the second main connecting bar 220 to be arranged at a closer distance on the insulating bracket 100.

[0038] like Figure 2 As shown, based on the design that the insulating bracket 100 includes the first sealing cover 131, in one embodiment of the present disclosure, the first sealing cover 131 and the retaining wall 111 can be connected by a snap-fit ​​structure to achieve quick-disconnect assembly. For example, the first sealing cover 131 can be provided with a first snap 1311, and the retaining wall 111 can be provided with a snap groove 1113 at a position corresponding to the first snap 1311, and the first snap 1311 and the snap groove 1113 are snap-fitted to achieve quick-disconnect assembly of the first sealing cover 131 and the retaining wall 111. In some other embodiments of the present disclosure, the first sealing cover 131 and the retaining wall 111 can also be connected by other methods, such as bonding, connecting with a connector, etc., which is not limited to this embodiment.

[0039] like Figure 1 , Figure 2 and Fig. 9 As shown, in one embodiment of the present disclosure, the insulating bracket 100 proposed in the present disclosure may also include a second sealing cover 132, which is detachably connected to the retaining wall 111, and the second sealing cover 132 is specifically located above at least a portion of the second storage space. Through the above design, the present disclosure can use the second sealing cover 132 to shield at least a portion of the second storage space, further protect the second main connection row 220 from impact and collision from above, and at the same time prevent dust and impurities from falling into the second storage space, thereby improving the connection reliability of the second main connection row 220. In addition, the second sealing cover 132 can also be made of insulating material, thereby further improving the insulation effect, for example, Fig.10As shown, when the second main connecting bar 220 has been connected to the insulating bracket 100 and the first main connecting bar 210 and the insulating bracket 100 need to be disassembled or connected and assembled, the second sealing cover 132 can be installed on the bracket body 110 to prevent the operator from contacting the second main connecting bar 220, further improving safety, and further facilitating the first main connecting bar 210 and the second main connecting bar 220 to be arranged at a closer distance on the insulating bracket 100.

[0040] like Figure 2 As shown, based on the design that the insulating bracket 100 includes the second sealing cover 132, in one embodiment of the present disclosure, the second sealing cover 132 and the retaining wall 111 can be connected by a snap-fit ​​structure to achieve quick-disconnect assembly. For example, the second sealing cover 132 can be provided with a second snap 1321, and the retaining wall 111 can be provided with a snap groove 1113 at a position corresponding to the second snap 1321, and the second snap 1321 and the snap groove 1113 are snap-fitted to achieve quick-disconnect assembly of the second sealing cover 132 and the retaining wall 111. In some other embodiments of the present disclosure, the second sealing cover 132 and the retaining wall 111 can also be connected by other methods, such as bonding, connecting with a connector, etc., which is not limited to this embodiment.

[0041] like Figure 5 , Figures 9 to 11 As shown, in one embodiment of the present disclosure, the first main connection row 210 is connected to the first region 1102 via at least two first connection members (e.g., bolts 1122), such as but not limited to the two first connection members shown in the figure. Also, the second main connection row 220 is connected to the second region 1103 via at least two second connection members (e.g., bolts 1122), such as but not limited to the two second connection members shown in the figure. The first connection member and the second connection member may also be connected according to Figure 5 , Figure 7 and Figure 8 It can be understood by the first connecting hole 112 or the nut 1121 in the first area 1102 and the second area 1103 shown in the figure. On this basis, at least two first connecting members are arranged along a first direction, and the first direction is parallel to the first connecting surface 1101. The first direction is, for example, the direction D1 shown in the figure, and at least two second connecting members are arranged along a second direction, and the second direction is parallel to the first connecting surface and intersects with the first direction, for example, is perpendicular to the first direction, and the second direction is, for example, the direction D2 shown in the figure. Through the above design, the present disclosure designs the arrangement direction of the connecting members of the first main connecting row 210 and the second main connecting row 220 to be intersecting, which can achieve a more reasonable structural design of the bracket body 110, avoid the problem of excessive space occupation caused by the arrangement direction of the first connecting member being parallel to the arrangement direction of the second connecting member, and is beneficial to the layout inside the battery box. For example, with Figure 5For example, when the two first connecting members and the two second connecting members are arranged along the direction D1, the size of the bracket body 110 along the direction D1 will be too large. For another example, when the two first connecting members and the two second connecting members are arranged along the direction D2, the size of the portion of the bracket body 110 corresponding to the first area 1102 (such as the first frame described below) along the direction D2 will be too large.

[0042] like Figure 5 As shown, in one embodiment of the present disclosure, the bracket body 110 may include a first frame 1104 and a second frame 1105, and the portion of the first connection surface 1101 located in the first frame 1104 is the above-mentioned first area 1102, and the portion of the first connection surface 1101 located in the second frame 1105 is the above-mentioned second area 1103. On this basis, along the second direction, the width of the first frame 1104 may be smaller than the width of the second frame 1105. Along the first direction, the width of the first frame 1104 may be greater than the width of the second frame 1105. Through the above design, since the present disclosure designs the arrangement direction of the connecting members of the first main connection row 210 and the second main connection row 220 to be in an intersecting form, different parts of the bracket body 110 can be set to different widths. The outer dimensions are suitable for the application of the insulating bracket 100 at different positions in the battery device, thereby avoiding the waste of space occupation caused by the uniform width of each part of the bracket body 110.

[0043] like Figures 1 to 5 As shown, in one embodiment of the present disclosure, the insulating bracket 100 proposed in the present disclosure may further include a heat-resistant layer 120. The heat-resistant layer 120 may be disposed on at least one side of the retaining wall 111, and the heat-resistant layer 120 is made of an insulating material. By utilizing the heat-resistant layer 120, the present disclosure can achieve heat-resistant protection for the retaining wall 111. Among them, the heat-resistant performance of the heat-resistant layer 120 is at least reflected in the following characteristics: when the outer temperature of the heat-resistant layer 120 reaches the jet temperature of the explosion-proof mechanism 411 when the single cell 410 has thermal runaway, the inner temperature of the heat-resistant layer 120 is less than or equal to the thermal deformation temperature of the material of the bracket body 110. In other words, when thermal runaway occurs in the battery device, the explosion-proof mechanism 411 of the single battery 410 releases the pressure and sprays the valve, and the heat flow sprayed by the explosion-proof mechanism 411 impacts the heat-resistant layer 120 and increases the temperature of the outside thereof. In this process, the heat-resistant property of the heat-resistant layer 120 is utilized to ensure that the temperature of the retaining wall 111 (i.e., the support body 110) inside the heat-resistant layer 120 will not rise to its thermal deformation temperature, that is, the retaining wall 111 can be prevented from being deformed by heat. Through the above design, the present disclosure can utilize the heat-resistant layer 120 provided on the retaining wall 111 to further improve the high temperature resistance of the insulating support 100, thereby effectively reducing the risk of thermal runaway of the battery device, ensuring that the high-voltage components will not be damaged by high temperature, and reducing the risk of fire in the battery device.

[0044] Based on the design that the insulating bracket 100 includes a heat-resistant layer 120, in one embodiment of the present disclosure, for the partial retaining wall 111 located between the first area 1102 and the second area 1103, the heat-resistant layer 120 can be respectively provided on the two side surfaces of the partial retaining wall 111 facing the first area 1102 and the second area 1103.

[0045] Based on the design that the insulating bracket 100 includes a heat-resistant layer 120, in one embodiment of the present disclosure, for the portion of the retaining wall 111 located in the edge area of ​​the bracket body 110, the heat-resistant layer 120 can be set on the outer side surface of the portion of the retaining wall 111. Of course, the heat-resistant layer 120 can also be set on the inner side surface of the portion of the retaining wall 111 located in the edge area, and it is not limited to this embodiment.

[0046] like Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, for a plurality of retaining walls 111 extending in different directions, the retaining wall 111 separating the first area 1102 and the second area 1103, that is, the retaining wall 111 located between the first area 1102 and the second area 1103 and extending along the direction D2 in the figure, can be provided with a heat-resistant layer 120 on both sides thereof. In addition to the above retaining walls 111, for other retaining walls 111, a heat-resistant layer 120 can be selectively provided only on the outer side thereof, or a heat-resistant layer 120 can be provided on both sides thereof. Through the above design, on the basis of ensuring the heat-resistant function and the arc-prevention effect, the present disclosure can reduce the amount of the heat-resistant layer 120, reduce the material cost, and simplify the assembly process.

[0047] In one embodiment of the present disclosure, when the retaining wall 111 is provided with a card slot 1113, the upper edge of the heat-resistant layer 120 can be lower than the position of the retaining wall 111 where the card slot 1113 is provided, so as to expose the card slot 1113 and facilitate the card connection and disassembly of the first sealing cover 131 and the second sealing cover 132.

[0048] like Figures 1 to 5 As shown, in one embodiment of the present disclosure, the heat-resistant layer 120 can also be provided on at least one side of the bracket body 110. Through the above design, the present disclosure can utilize the heat-resistant layer 120 to achieve heat-resistant protection for the bracket body 110, and further improve the high temperature resistance of the bracket body 110. At the same time, due to the improvement of the high temperature resistance of the bracket body 110, a more compact arrangement of the explosion-proof mechanism 411 of the single battery 410 and the insulating bracket 100 becomes possible, for example, the explosion-proof mechanism 411 can be arranged toward the insulating bracket 100, and the distance between the explosion-proof mechanism 411 and the insulating bracket 100 can be further reduced, which is further conducive to the improvement of the space utilization rate of the battery device.

[0049] See also Fig.12As shown, based on the design that the heat-resistant layer 120 is disposed on the side of the bracket body 110, in one embodiment of the present disclosure, when the insulating bracket 100 is applied to the battery device and the explosion-proof mechanism 411 of the single battery 410 faces the insulating bracket 100, the heat-resistant layer 120 can be disposed at least on the side of the bracket body 110 facing the explosion-proof mechanism 411. Through the above design, since the explosion-proof mechanism 411 is arranged toward the insulating bracket 100, when the explosion-proof mechanism 411 releases the pressure and sprays the valve, the ejected heat flow will directly impact the above-mentioned side of the bracket body 110. The present disclosure can utilize the heat-resistant layer 120 to further improve the high temperature resistance of the bracket body 110 and prevent the bracket body 110 from thermal deformation.

[0050] like Figures 2 to 4 As shown, in one embodiment of the present disclosure, part of the retaining wall 111 (for example, the retaining wall 111 other than the retaining wall 111 located between the first area 1102 and the second area 1103) can be arranged along the edge of the first connection surface 1101, so that one side of the part of the retaining wall 111 (for example, the side facing away from the first accommodating space or the side facing away from the second accommodating space) is flush with part of the side of the bracket body 110. Through the above design, the present disclosure can simplify the structural complexity of the bracket body 110 provided with the retaining wall 111, and simplify the manufacturing difficulty of the bracket body 110. In addition, when the above-mentioned side of the bracket body 110 is also provided with a heat-resistant layer 120, an integral heat-resistant layer 120 can also be provided at these positions, and the integral heat-resistant layer 120 covers the part of the retaining wall 111 and the bracket body 110 at the same time, so as to avoid the gap between the two parts of the retaining wall 111, which leads to weak local heat-resistant protection, and at the same time helps to reduce the number of parts and simplify the assembly process. In some other embodiments of the present disclosure, part of the retaining wall 111 arranged along the edge of the first connection surface 1101 and the corresponding side of the bracket body 110 can also be staggered to form a step structure, thereby further extending the creepage distance and further improving the insulation performance, which is not limited to this embodiment.

[0051] In one embodiment of the present disclosure, the heat-resistant layer 120 may be a ceramic composite tape. Through the above design, the present disclosure can further prevent arcing by utilizing the natural insulation advantages of the ceramic composite tape, and further improve the insulation performance. In some other embodiments of the present disclosure, the heat-resistant layer 120 may also be a heat-resistant structure of other materials or structural forms, and is not limited to this embodiment.

[0052] In one embodiment of the present disclosure, the thickness of the heat-resistant layer 120 can be 0.3mm~1.5mm, such as 0.3mm, 0.5mm, 1mm, 1.2mm, 1.5mm, etc. Through the above design, since the heat-resistant capacity of the heat-resistant layer 120 increases with its thickness, the present disclosure selects a suitable range for the thickness of the heat-resistant layer 120, which can avoid the heat-resistant performance being insufficient due to the thickness of the heat-resistant layer 120 being too small, such as failing to meet the design requirements of the heat-resistant properties of the above-mentioned heat-resistant layer 120. At the same time, the present disclosure can avoid the waste of materials caused by the excessive thickness of the heat-resistant layer 120, which is conducive to reducing material costs, reducing weight, and reducing space occupancy. In some other embodiments of the present disclosure, the thickness of the heat-resistant layer 120 can also be less than 0.3mm, or can be greater than 1.5mm, such as 0.29mm, 1.51mm, etc., and is not limited to this embodiment.

[0053] In one embodiment of the present disclosure, the material of the bracket body 110 (i.e., the material of the retaining wall 111) can be a liquid crystal polymer (LCP, also known as liquid crystal polymer, LCP plastic material, etc.), which has good insulation properties and certain heat resistance. In some other embodiments of the present disclosure, the material of the bracket body 110 can also be other materials, such as polyetheretherketone (PEEK), polyimide (PI), etc., and is not limited to this embodiment.

[0054] As mentioned above, taking the case where the material of the support body 110 is a liquid crystal polymer, the heat-resistant layer 120 is a ceramic composite tape with a thickness of 0.3 mm as an example, after testing, when the front temperature of the 0.3 mm thick ceramic composite tape is 500°C, the back temperature can be lower than 350°C. In other words, the present disclosure uses a ceramic composite tape, and when the temperature of the pressure relief valve of the single battery 410 is 500°C, the back temperature of the ceramic composite tape (i.e., the side facing the support body 110) can be kept below 350°, that is, the temperature of the support body 110 is kept lower than the minimum thermal deformation temperature of its own material. Based on this, it can be seen that by using the heat-resistant layer 120, the present disclosure can provide reliable heat-resistant protection for the retaining wall 111 (support body 110), and significantly improve the high temperature resistance of the insulating support 100.

[0055] In one embodiment of the present disclosure, the heat-resistant layer 120 may be provided on the retaining wall 111 and the bracket body 110 by bonding.

[0056] like Figures 5 to 7As shown, in one embodiment of the present disclosure, the first area 1102 and the second area 1103 of the first connection surface 1101 may be respectively provided with a first connection hole 112, and a nut 1121 is provided in the first connection hole 112. On this basis, the first main connection row 210 may be connected to the nut 1121 located in the first area 1102 via a bolt 1122, and the second main connection row 220 may be connected to the nut 1121 located in the second area 1103 via a bolt 1122.

[0057] like Figure 7 As shown, based on the design that the nut 1121 is provided in the first connection hole 112, in one embodiment of the present disclosure, the top surface of the nut 1121 can protrude from the first connection surface 1101. For example, the height of the top surface of the nut 1121 protruding from the first connection surface 1101 can be 0.5mm~2mm, such as 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 2mm, etc. Through the above design, the present disclosure can ensure that the bolt 1122 and the nut 1121 are hard-linked when they are locked, and avoid the situation where the bolt 1122 is torqued back.

[0058] Based on the design that a nut 1121 is provided in the first connecting hole 112 , in one embodiment of the present disclosure, the nut 1121 may be an insert nut, wherein the insert nut and the bracket body 110 may be manufactured by an integral injection molding process.

[0059] like Figures 1 to 6 , Figure 8 As shown, in one embodiment of the present disclosure, the bracket body 110 may be provided with a mounting portion 113, and the mounting portion 113 has a second connection surface 1131, and the second connection surface 1131 is parallel to the first connection surface 1101. The second connection surface 1131 may be provided with a second connection hole 114, and a bushing 1141 is provided in the second connection hole 114. On this basis, the bracket body 110 can be connected to the bracket body 110 by a rivet bolt 1142 (for example, see Fig.14 Through the above design, the present disclosure utilizes the rivet bolt 1142 and the bushing 1141 to achieve a fixed connection between the insulating bracket 100 and the battery box, and can ensure the reliability of the connection structure and avoid shaking and abnormal noise.

[0060] Based on the design that the bushing 1141 is provided in the second connection hole 114 , in one embodiment of the present disclosure, the bushing 1141 may be an insert bushing, wherein the insert bushing and the bracket body 110 may be manufactured by an integral injection molding process.

[0061] like Figure 8As shown, based on the design that the bushing 1141 is provided in the second connection hole 114, in one embodiment of the present disclosure, the top surface of the bushing 1141 can protrude from the second connection surface 1131. For example, the height of the top surface of the bushing 1141 protruding from the second connection surface 1131 can be 0.5mm~2mm, such as 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 2mm, etc. Through the above design, the present disclosure can ensure that the rivet bolt and the bushing 1141 are hard-linked when they are locked, avoiding the occurrence of torque back-twisting of the rivet bolt.

[0062] like Figures 1 to 6 , Figure 8 As shown, based on the design that the bracket body 110 is provided with the mounting portion 113, in one embodiment of the present disclosure, the mounting portion 113 may be provided with a receiving groove 1132, and the receiving groove 1132 is used to receive a part of the structure of the rivet bolt, such as the part of the rivet bolt extending out of the bushing 1141, and the second connection surface 1131 is the bottom of the receiving groove 1132. Through the above design, the present disclosure can receive the rivet bolt in the second connection hole 114 (bushing 1141) and the receiving groove 1132, avoid the rivet bolt from being exposed, and ensure the connection stability and reliability between the insulating bracket 100 and the battery box.

[0063] like Figure 6 As shown, in one embodiment of the present disclosure, the bracket body 110 may be provided with a positioning column 115, which extends along the assembly direction when the insulating bracket 100 is installed in the battery box, for example, Fig.12 and Fig.14 Taking the structure shown as an example, when the insulating bracket 100 is arranged on the top of the longitudinal beam 310, that is, when the assembly direction of the insulating bracket 100 when it is installed in the battery case is the height direction of the battery case, the positioning column 115 extends downward from the bracket body 110 along the height direction. On this basis, the positioning column 115 can be inserted into the positioning hole provided in the battery case or positioned and matched with other corresponding positioning structures. Through the above design, the present disclosure can utilize the positioning column 115 to achieve the positioning and matching of the insulating bracket 100 when it is assembled in the battery case, and further improve the connection stability and reliability. At the same time, during the assembly process of the insulating bracket 100 and the battery case, the present disclosure can utilize the positioning column 115 to realize the guiding function, guide the insulating bracket 100 to move to the predetermined installation position of the battery case, reduce the difficulty of assembly, and improve the assembly efficiency.

[0064] It should be noted here that the insulating support 100 shown in the drawings and described in this specification are only a few examples of many kinds of insulating support 100 that can adopt the principles of the present disclosure. It should be clearly understood that the principles of the present disclosure are by no means limited to any details or any components of the insulating support 100 shown in the drawings or described in this specification.

[0065] Based on the above detailed description of several exemplary embodiments of the insulating bracket 100 proposed in the present disclosure, an exemplary embodiment of the battery device proposed in the present disclosure will be described below.

[0066] See also Fig.12 , which representatively shows a partial enlarged view of the battery device proposed in the present disclosure. In this exemplary embodiment, the battery device proposed in the present disclosure is described by taking a vehicle-mounted power battery as an example. It is easy for those skilled in the art to understand that in order to apply the relevant design of the present disclosure to other types of battery devices, various modifications, additions, substitutions, deletions or other changes are made to the specific embodiments described below, and these changes are still within the scope of the principle of the battery device proposed in the present disclosure.

[0067] Related References Fig.13 and Fig.14 , Fig.13 A representative example is shown in Fig.12 A top view of Fig.14 The representative diagram shows the Fig.13 The following is a cross-sectional schematic diagram of the straight line DD in FIG. In conjunction with the above drawings, the structure, connection mode and functional relationship of the main components of the battery device proposed in the present disclosure will be described in detail.

[0068] like Fig.12 and Fig.13 As shown, in one embodiment of the present disclosure, the battery device proposed in the present disclosure includes a battery box and an insulating bracket 100 proposed in the present disclosure and described in detail in the above embodiments. The battery box is used to accommodate a single battery 410, and the insulating bracket 100 is disposed in the battery box.

[0069] like Figure 12 to Figure 14 As shown, in one embodiment of the present disclosure, the battery device proposed in the present disclosure includes a battery column 400, and the battery column 400 includes a plurality of single cells 410 arranged along a third direction (for example, refer to the direction D3 shown in the figure). A longitudinal beam 310 is provided in the battery box, and the longitudinal beam 310 extends along the third direction. On this basis, the insulating bracket 100 can be provided on the longitudinal beam 310, that is, the bracket body 110 is connected to the longitudinal beam 310 and is located at the end of the longitudinal beam 310.

[0070] like Fig.12 and Fig.13As shown, the battery device proposed in the present disclosure may include two battery columns 400, which are respectively located on both sides of the longitudinal beam 310 in the fourth direction (for example, refer to the direction D4 shown in the figure), the fourth direction is perpendicular to the third direction, and each single battery 410 belonging to the same battery column 400 has a lead-out structure (not shown in the figure) through series-parallel connection. On this basis, the first main connecting bar 210 includes a first sub-connecting bar 211, and the second main connecting bar 220 includes a third sub-connecting bar 221. One end of each of the first sub-connecting bar 211 and the third sub-connecting bar 221 is respectively connected to the insulating bracket 100, and the other end of each is respectively connected to the lead-out structure of the two battery columns 400.

[0071] like Figure 12 to Figure 14 As shown, based on the design that the insulating bracket 100 is arranged on the longitudinal beam 310, in one embodiment of the present disclosure, the arrangement direction of the first area 1102 and the second area 1103 of the first connection surface 1101 of the bracket body 110 can be the same as the extension direction of the longitudinal beam 310, for example, refer to the direction D3 shown in the figure (in other words, in this embodiment, Figures 1 to 5 The direction D1 shown may be parallel to the path 12 to Fig.14 Direction D3 shown).

[0072] like Fig.12 and Fig.13 See also Figure 5In one embodiment of the present disclosure, the battery device includes a battery column 400, and the battery column 400 includes a plurality of single cells 410 arranged along a third direction, and the third direction may be the direction D3 in the figure. A longitudinal beam 310 is provided in the battery box, and the longitudinal beam 310 extends along the third direction and is located on the side of the battery column 400 in a fourth direction, and the fourth direction is perpendicular to the third direction, and the fourth direction may be the direction D4 in the figure. The longitudinal beam 310 has a first part and a second part arranged along the third direction, and the first part is a part of the longitudinal beam 310 that overlaps with the battery column 400 in projection, that is, a part of the longitudinal beam 310 that is arranged corresponding to the position of the battery column 400 in the third direction, and the second part is a part of the longitudinal beam 310 that does not overlap with the battery column 400 in projection, that is, a part of the longitudinal beam 310 that is not arranged corresponding to the position of the battery column 400 in the third direction, or it can be understood as a part of the longitudinal beam 310 that is arranged corresponding to the position of other components (such as end plates, etc.) in the third direction. On this basis, the bracket body 110 can be connected to the longitudinal beam. Among them, the first area 1102 (or the first frame 1104 of the bracket body 110) is located in the first part of the longitudinal beam 310, the second area 1103 (or the second frame 1105 of the bracket body 110) is located in the second part of the longitudinal beam 310, and the first direction is parallel to the third direction, such as the direction D1 and the direction D3 shown in the figure. Through the above design, the present disclosure uses the arrangement direction of the connecting members of the first main connecting row 210 and the second main connecting row 220 to be designed in an intersecting form, which can further reduce the width of the first frame 1104 in the fourth direction (i.e., the second direction), so that the first part of the longitudinal beam 310 corresponding to the first frame 1104 can also be designed to be smaller in width than the second part, thereby further reducing the space occupied by the longitudinal beam 310 on the side of the battery column 400, and further improving the energy density of the battery device.

[0073] Based on the design that the insulating support 100 is arranged on the longitudinal beam 310 of the battery box, in one embodiment of the present disclosure, the battery device proposed in the present disclosure can adopt an upper and lower layered structure. For example, the battery box has a battery compartment and an electrical compartment, the battery compartment is used to accommodate a single battery 410, and the electrical compartment is located above the battery compartment and is at least used to accommodate a high-voltage device (such as BDM, etc.). On this basis, the two ends of the first main connecting bar 210 extend to the battery compartment and the electrical compartment respectively, and are respectively connected to the single battery 410 and the high-voltage device, and the two ends of the second main connecting bar 220 extend to the battery compartment and the electrical compartment respectively, and are respectively connected to the single battery 410 and the high-voltage device. For example, the two ends of the main connecting bar (such as the first main connecting bar 210 and the second main connecting bar 220) can extend to the upper layer and the lower layer respectively and be connected to the battery part and the high-voltage control part, that is, the insulating support 100 proposed in the present disclosure can be used as a transition structure between the upper and lower layers. Specifically, the middle part of the main connecting bar can be connected to the insulating support 100, and the so-called middle part refers to any area of ​​the main connecting bar except the two ends. Furthermore, the main connection bar can also adopt a split design, that is, the main connection bar can include two parts, for example, the first main connection bar 210 can include a first sub-connection bar 211 and a second sub-connection bar 212. Among them, one end of each of the first sub-connection bar 211 and the second sub-connection bar 212 is commonly connected to the first area 1102 of the first connection surface 1101 of the bracket body 110, the other end of the first sub-connection bar 211 is connected to the battery part, for example, connected to the pole of the single battery 410, and the other end of the second sub-connection bar 212 is connected to the high-voltage device, for example, connected to the positive electrode interface of the BDU. Similarly, the second main connection bar 220 can include a third sub-connection bar 221 and a fourth sub-connection bar 222. Among them, each end of the third sub-connection row 221 and the fourth sub-connection row 222 is commonly connected to the second area 1103 of the first connection surface 1101 of the bracket body 110, the other end of the third sub-connection row 221 is connected to the battery part, for example, connected to the pole of the single cell 410, and the other end of the fourth sub-connection row 222 is connected to the high-voltage device, for example, connected to the negative electrode interface of the BDU.

[0074] It should be noted that in some other embodiments of the present disclosure, the battery device proposed in the present disclosure may also adopt other structural forms, and is not limited to the above-mentioned upper and lower layered structures. For example, the internal space of the battery box may include a battery compartment and an electrical compartment arranged in a horizontal direction, the battery compartment is used to accommodate the battery part (i.e., the battery column 400, the single battery 410), and the electrical compartment is used to accommodate electrical parts including the high-voltage control part (such as high-voltage devices such as BDU). Among them, a partition beam may be provided in the battery box, and the partition beam is located between the battery compartment and the electrical compartment to separate the two parts of the compartment body. On this basis, the insulating bracket 100 can also be provided on the partition beam of the battery box, and of course it can also be provided on other structures such as the longitudinal beam 310.

[0075] like Fig.12As shown, in one embodiment of the present disclosure, an explosion-proof mechanism 411 may be provided on one side of the single cell 410 facing the insulating support 100. Of course, in some embodiments, the explosion-proof mechanism 411 may also be provided on other sides of the single cell 410. For example, the battery device proposed in the present disclosure includes a battery column 400, and the battery column 400 includes a plurality of single cells 410 arranged along a third direction (for example, refer to the direction D3 shown in the accompanying drawings). A longitudinal beam 310 is provided in the battery box, and the longitudinal beam 310 extends along the third direction. The support body 110 is connected to the longitudinal beam 310. On this basis, an explosion-proof mechanism 411 may be provided on the side of the single cell 410 parallel to the third direction and facing the insulating support 100, and on a reference plane parallel to the side, the orthographic projection figure of the explosion-proof mechanism 411 at least partially overlaps with the orthographic projection figure of the insulating support 100. Through the above design, the battery device proposed in the present disclosure adopts a design in which the explosion-proof mechanism 411 of some single cells 410 is arranged toward the insulating support 100. When the single cell 410 has thermal runaway, the explosion-proof mechanism 411 releases the pressure and sprays the valve, and the sprayed heat flow will directly impact the insulating support 100. In this regard, since the insulating support 100 adopts the design of the heat-resistant layer 120, the high-temperature resistance of the insulating support 100 can be improved, so that the insulating support 100 can withstand the spray valve impact of the explosion-proof mechanism 411 during thermal runaway, thereby making it possible for the battery device to adopt the above-mentioned more compact structural arrangement scheme, which is conducive to improving the energy density of the battery device. Further, when the heat-resistant layer 120 is also provided on some sides of the support body 110, for example, when the side of the support body 110 facing the explosion-proof mechanism 411 (i.e., the side perpendicular to the direction D4 and parallel to the direction D3 shown in the figure) is provided with the heat-resistant layer 120, the present disclosure can further improve the high-temperature resistance of the relevant position of the insulating support 100. In some other embodiments of the present disclosure, on the above-mentioned reference plane, the orthographic projection pattern of the explosion-proof mechanism 411 and the orthographic projection pattern of the insulating bracket 100 may not overlap at all. Since the explosion-proof mechanism 411 releases the pressure when the valve is sprayed, the heat flow is ejected in a conical dispersion manner. At this time, the ejected high-temperature material may still splash onto the heat-resistant layer 120 provided on the insulating bracket 100. Then the heat-resistant layer 120.

[0076] In one embodiment of the present disclosure, the battery box may include a cover plate and a battery tray, and the cover plate is arranged on the top of the battery tray and closes the top opening of the battery tray. Specifically, the battery tray can be arranged at the bottom of the vehicle body floor, and the body floor can be used as a cover plate of the battery box to close the top opening of the battery tray. For example, the top of the battery tray can be connected to the body floor, and such a structure of the battery device can refer to the CTB (Cell to Body) battery structure.
