Technical Field

[0001] This application relates to the field of power battery technology, and in particular to a mounting bracket, battery pack and electrical equipment. Background Technology

[0002] Currently, electrical modules such as the BMU (Battery Management Unit) are the core components of the BMS (Battery Management System). The BMU (hereinafter referred to as the control board structure) is usually fixed to the battery pack housing by a mounting bracket. It is mainly responsible for monitoring parameters such as voltage, current and temperature of individual battery cells. By collecting these data, it can understand the status of the battery in real time and ensure that the battery works normally.

[0003] In related technologies, the mounting bracket includes a mounting base and bolt fasteners. The mounting base is fixed to the battery pack housing. The mounting base has multiple mounting holes at its four corners, and the control board structure has multiple positioning holes at its four corners. The bolt fasteners pass through the positioning holes of the control board structure and the mounting holes of the mounting base to fix the control board structure onto the mounting bracket.

[0004] However, the inventors recognized that in practical use, due to the inconsistent dimensions of control board structures from different manufacturers (e.g., different specifications), the positions of the mounting holes for the mounting base used to fix the control board structure are different, resulting in poor versatility of the mounting bracket.

[0047] Figure 1 This is an exploded structural diagram of the mounting bracket and control board structure according to some embodiments of this application.

[0048] One or more embodiments of this application disclose a mounting bracket. (See also...) Figure 1 The mounting bracket includes a mounting base 1, a sliding device 2, and a clamping device. The mounting base is formed in a mounting groove. The sliding device 2 is fixed inside the mounting base 1. The clamping device includes a clamping assembly 3, which forms a clamping space for clamping the control board structure 4 between the clamping assembly 3 and the groove wall of the mounting groove. The clamping assembly 3 and the sliding device 2 are slidably connected in a first direction to adjust the length of the clamping space.

[0049] In at least one embodiment, the mounting base 1 can be mounted on the battery box housing of the battery pack.

[0050] The first direction can refer to the direction in which two adjacent clamping components 3 are relatively close or far apart, or it can refer to the length direction of the mounting base 1, or it can refer to the extension direction of the sliding device 2. The first direction can be related to... Figure 1 The X-axis is parallel in the coordinate system.

[0051] The clamping device includes at least one clamping component 3. For example, if the clamping device includes a clamping component 3, the clamping component 3 and the side wall of the mounting groove along the first direction and the two side walls along the second direction together form a clamping space. The side wall of the mounting groove corresponding to the clamping component 3 may be provided with a bayonet, so that the clamping component 3 cooperates with the bayonet to realize the clamping and fixing operation of the control board structure 4.

[0052] If the clamping device includes two clamping components 3, the two clamping components 3 can be spaced apart and arranged opposite each other along a first direction. The two clamping components spaced apart along the first direction, together with the two sidewalls of the mounting groove along a second direction, together form a clamping space. The second direction can be... Figure 1 The Y-axis is parallel in the coordinate system.

[0053] The clamping assembly 3 is slidably connected to the sliding device 2 along the first direction, so that the clamping assembly 3 can move relative to the sliding device 2 along the first direction to adjust the length of the clamping space.

[0054] The mounting bracket includes a mounting base 1, a sliding device 2, and a clamping device. The sliding device 2 is fixed in the mounting groove of the mounting base 1, and the clamping components 3 arranged at intervals along the first direction in the clamping device are slidably connected to the sliding device 2, so that the clamping components 3 arranged along the first direction are movably mounted on the mounting base 1 through the sliding device 2.

[0055] Since the clamping assembly 3 is used to move relative to the sliding device 2 along the first direction, a clamping space for accommodating the control board structure is formed between the clamping assembly and the groove wall of the mounting groove. The clamping assembly 3 can be adjusted to move relative to the sliding device 2 along the first direction according to the length of the control board structure 4 from different manufacturers (e.g., different specifications). This adjusts the length of the clamping space formed between the two clamping assemblies 3 arranged along the first direction, thereby enabling clamping operations on control board structures 4 of different specifications and improving the universality of the mounting bracket for installing the control board structure 4.

[0056] Figure 2 This is a schematic diagram of the mounting bracket and the first control board 41 according to some embodiments of this application; Figure 3 This is one of the partial schematic diagrams of the sliding device 2 and the clamping device according to some embodiments of this application.

[0057] In some embodiments, combined with Figure 2 and Figure 3 As shown, the sliding device 2 includes a first slide rail structure 21, and the clamping assembly 3 includes a fixed base 31, a first clamping part 33, and a connecting member 32. The fixed base 31 is slidably connected to the first slide rail structure 21, and the fixed base 31 is fixed to the first slide rail structure 21 through the connecting member 32. The first clamping part 33 is connected to the fixed base 31.

[0058] The control board structure 4 includes a first control board 41, and the clamping space for clamping the first control board 41 is formed between the first clamping part 33 and the groove wall of the mounting groove.

[0059] In at least one embodiment, the first slide rail structure 21 may extend along a first direction and may be fixed to the inner wall of the mounting base 1 by means of welding, bonding or other methods.

[0060] The connector 32 can be connected to the fixed base 31 and the first slide rail structure 21 in the following ways: for example, the connector 32 can be a bolt fastener, the fixed base 31 can be placed on the first slide rail structure 21, the first slide rail structure 21 is provided with a first adjustment hole 210, the first adjustment hole 210 is parallel to the extending direction of the first slide rail structure 21, and the connector 32 passes through the first adjustment hole 210 of the fixed base 31 and the first slide rail structure 21 to realize the movable connection between the fixed base 31 and the first slide rail structure 21. The first adjustment hole 210 can be a rectangular hole or an oblong hole.

[0061] Each clamping component 3 includes at least one first clamping part 33, so the clamping device may include at least two first clamping parts 33. The at least two first clamping parts 33 are arranged at intervals along a first direction. The clamping space includes a first clamping area. A first clamping area for clamping the first control plate 41 is formed between at least two adjacent first clamping parts 33. The first slide rail structure 21 extends along the first direction. The at least two first clamping parts 33 are slidably connected to the first slide rail structure 21 through corresponding fixing seats 31.

[0062] When different specifications, such as different lengths of first control plates 41, need to be installed, the connector 32 is loosened, and the fixing seat 31 in the corresponding clamping assembly 3 can be operated to drive the first clamping part 33 to move along the first direction, so as to adjust the length of the first clamping area between the two first clamping parts 33 corresponding to the two clamping assemblies 3, so as to clamp the first control plates 41 of different lengths; when it is necessary to adjust the position of the first control plate 41 along the first direction, the two first clamping parts 33 can be adjusted and the first control plate 41 can be driven to move along the first direction, so as to realize the position adjustment operation of the first control plate 41 relative to the mounting seat 1 along the first direction.

[0063] Figure 4 This is one of the partial structural schematic diagrams of the clamping component 3 according to some embodiments of this application.

[0064] In some embodiments, combined with Figure 4 As shown, the first clamping part 33 includes a first clamping plate 331 and a first fastener 332. The first clamping plate 331 is provided with a first slot 3310. The first slot 3310 is used to receive the edge of the first control plate 41. The first fastener 332 passes through the first clamping plate 331 and extends into the first slot 3310 to abut against the first control plate 41.

[0065] In at least one embodiment, the first clamping plate 331 may be a plate-like structure with a first slot 3310, the width of which is greater than or equal to the edge thickness of the first control plate 41. The first fastener 332 may be a bolt fastener. The first slot 3310 is located along... Figure 4 The dimension along the Z-axis in the coordinate system is the width of the first slot 3310, and the first control plate 41 is along... Figure 4 The dimension in the Z-axis direction of the coordinate system is the edge thickness of the first control plate 41.

[0066] The first control plate 41 can be fixed in the following way: for example, the two ends of the first control plate 41 along the first direction are respectively inserted into the first slots 3310 of the two first clamping parts 33, and the first fastener 332 is rotated so that the first fastener 332 passes through the first clamping plate 331 and abuts against the first control plate 41, thereby realizing the clamping and fixing operation of the first control plate 41; furthermore, the tightness of the first fastener 332 can be adjusted to be suitable for clamping first control plates 41 of different thicknesses.

[0067] In some embodiments, combined with Figure 3 and Figure 4 As shown, the clamping assembly 3 further includes a connecting shaft 34, which passes through the end of the fixed base 31 away from the first slide rail structure 21 and the first clamping part 33. The first clamping part 33 is used to rotate relative to the fixed base 31 about the axis of the connecting shaft 34.

[0068] In at least one embodiment, the connecting shaft 34 extends along a first direction, and the axis of the connecting shaft 34 is parallel to the first direction. The connecting shaft 34 may adopt a pin structure, bolt structure, rod-like member, etc., and is not specifically limited thereto.

[0069] The connecting shaft 34 can be inserted into the first clamping part 33 in the following manner: for example, the first clamping part 33 also includes a first cylindrical part 333, the first cylindrical part 333 is fixedly connected to the first clamping plate 331, and the connecting shaft 34 is inserted into the end of the fixed seat 31 away from the first slide rail structure 21 and the first cylindrical part 333. Therefore, the cooperation between the first cylindrical part 333 and the connecting shaft 34 not only realizes the disassembly and assembly of the first clamping part 33 and the fixed seat 31, but also drives the first control plate 41 to rotate relative to the fixed seat 31 around the axis of the connecting shaft 34, thereby realizing the adjustment of the installation angle of the first control plate 41.

[0070] In some embodiments, combined with Figure 4 As shown, the first clamping part 33 has a notch 3311 at the end away from the first control plate 41, and the fixing seat 31 is located in the notch 3311. Along the second direction, the size of the notch 3311 is larger than the size of the mounting seat 1.

[0071] In at least one embodiment, since the second direction is compatible with... Figure 4 The Y-axis in the coordinate system is parallel and can refer to the width direction of mounting base 1.

[0072] The first clamping plate 331 of the first clamping part 33 has a notch 3311 at the end away from the first control plate 41. Along the second direction, the size of the notch 3311 is larger than the size of the mounting base 1.

[0073] Since the size of the notch 3311 is larger than the size of the mounting base 1 along the second direction, at least part of the edge of the fixing base 31 is inside the notch 3311. This allows the notch 3311 to abut against the edge of the fixing base 31 after rotating at a predetermined angle, based on the first clamping part 33 rotating about the connecting shaft 34 relative to the fixing base 31 to adjust the mounting angle of the first control plate 41. Thus, the edge of the notch 3311 can also lock the position of the first clamping part 33 after rotation.

[0074] In some embodiments, combined with Figure 3 and Figure 4 As shown, the sliding device 2 includes a plurality of first slide rail structures 21, which are arranged at intervals along a second direction; the fixed base 31 is provided with a second adjustment hole 310, which extends along the second direction; the connecting member 32 passes through the second adjustment hole 310 and is connected to the corresponding first slide rail structure 21; the second direction refers to the width direction of the mounting base 1 (reference). Figure 4 (in the Y-axis direction).

[0075] In at least one embodiment, the sliding device 2 includes a plurality of, for example, two or four, first slide rail structures 21. When the number of first slide rail structures 21 is two, the two first slide rail structures 21 are arranged at intervals along the second direction. In this case, the length of each first slide rail structure 21 is greater than the distance between the two first clamping portions 33, and the two fixing seats 31 can be slidably connected to the same first slide rail structure 21. Figure 3 As shown, when there are four first slide rail structures 21, the four first slide rail structures 21 are arranged in a quadrilateral shape, and the two fixed seats 31 can be slidably connected to different first slide rail structures 21.

[0076] The second direction can be combined with Figure 3 The Y-axis is parallel in the coordinate system.

[0077] Two second adjustment holes 310 are provided on each fixed seat 31, which are spaced apart along the second direction and extend along the second direction. Therefore, the second adjustment holes 310 can be rectangular holes or oblong holes.

[0078] Since each of the second adjustment holes 310 of the fixed base 31 extends along the second direction, and the connecting member 32 passes through the second adjustment hole 310 and is connected to the first adjustment hole 210 of the first slide rail structure 21, the connecting member 32 can also move in the second adjustment hole 310 along the second direction, so as to adjust the first control plate 41 back and forth by adjusting the fixed base 31 to move along the second direction; and since the first adjustment hole 210 of the first slide rail structure 21 extends along the first direction, the connecting member 32 and the fixed base 31 can also move relative to the first slide rail structure 21 along the first direction, so as to adjust the first control plate 41 along the first direction, thereby increasing the position adjustment range of the first control plate 41.

[0080] Part Two Figure 7 For two second clamping parts 37 and a second control plate 42 according to some embodiments of this application

[0081] A schematic diagram of the explosion structure.

[0082] In some embodiments, combined with Figure 5 and Figure 7 As shown, the clamping assembly 3 further includes a connecting rod 35, a second clamping part 37, and a second fastener 36. The connecting rod 35 includes a connecting rod body 351, which is connected to the fixed base 31. The sliding device 2 includes a second slide rail structure 22. The end of the connecting rod body 351 in the extending direction is connected to the second slide rail structure 22 through the second fastener 36. The second clamping part 37 is spaced apart from the connecting rod body 351 along the first direction, and the second clamping part 37 and the second slide rail structure 22 are slidably connected along the first direction.

[0083] The control board structure 4 further includes a second control board 42, and the clamping space for clamping the second control board 42 is formed between the second clamping part 37 and the groove wall of the mounting groove.

[0084] In at least one embodiment, the connecting rod 35 and the first clamping part 33 may be located on opposite sides of the fixing seat 31. Specifically, the first clamping part 33 is located on the side of one fixing seat 31 facing the other fixing seat 31, and the connecting rod 35 and the second clamping part 37 are located on the side of one fixing seat 31 away from the other fixing seat 31.

[0085] A connecting rod 35 can be installed on each fixed base 31. The end of the connecting rod body 351 of each connecting rod 35 along the second direction is connected to the corresponding second slide rail structure 22 by a second fastener 36. The second clamping part 37 is connected to the corresponding second slide rail structure 22. The second fastener 36 can be a bolt fastener.

[0086] A first threaded hole can be opened at the end of the connecting rod body 351 in the extension direction, and a second fastener 36 is inserted into the first threaded hole of the second slide rail structure 22 and the connecting rod body 351 to achieve a fixed connection between the connecting rod body 351 and the second slide rail structure 22.

[0087] The second clamping part 37 and the connecting rod body 351 of the connecting rod 35 are arranged at intervals along the first direction and are connected and fixed by the second slide rail structure 22.

[0088] The clamping space also includes a second clamping area. If the clamping device includes a second clamping part 37, the second clamping part 37, together with one side wall of the mounting groove along the first direction and the two side walls of the mounting groove along the second direction, form a second clamping area. If the clamping device includes at least two second clamping parts 37, the two second clamping parts 37 arranged at intervals along the first direction, together with the two side walls of the mounting groove along the second direction, form a second clamping area. The second control plate 42 is located within the second clamping area.

[0089] The second clamping area can be located above the first clamping area; therefore, the second control board 42 can also be located within the second clamping area.

[0090] Two second clamping parts 37 arranged at intervals along the first direction cooperate to clamp the second control board 42; the second control board 42 and the first control board 41 can be electrically connected through a ribbon cable.

[0091] The second clamping part 37 can be connected to the fixed base 31 via the second slide rail structure 22 and the connecting rod 35. The two second clamping parts 37 are spaced apart along the first direction, and the two second clamping parts 37 are used to clamp and install the second control plate 42. The distance between the two second clamping parts 37 can be adjusted by moving the second clamping parts 37 relative to the corresponding second slide rail structure 22 along the first direction. This is applicable to clamping and fixing operations of second control plates 42 of different specifications, such as different lengths.

[0092] Alternatively, the first control board 41 can be clamped only by the first clamping part 33, or the second control board 42 can be clamped only by the second clamping part 37, to achieve the installation of a single-layer control board; or, the first clamping part 33 can clamp the first control board 41 and the second clamping part 37 can clamp the second control board 42, to achieve the installation of a double-layer control board. With the same mounting slot volume, the double-layer control board has a larger circuit board area and thus a greater number of detection points compared to the single-layer control board; while the single-layer control board has a larger heat dissipation space and better heat dissipation effect compared to the double-layer control board. Therefore, users can flexibly choose the installation method of single-layer or double-layer control boards according to the actual site conditions.

[0093] Among them, the double-layer control board is compatible with BMU structures (control board structures) from different manufacturers, can adapt to BMU structures (control board structures) of different sizes, and can be installed with or without a shell. Both single-layer and double-layer structures can be installed to achieve rapid matching of customer needs.

[0094] Figure 6 This is a second partial structural schematic diagram of the clamping component 3 according to some embodiments of this application.

[0095] In some embodiments, combined with Figure 6 As shown, the second clamping part 37 includes a third fastener 371, a connecting seat 372, and a second clamping plate 373. The end of the connecting seat 372 is connected to the second slide rail structure 22 through the third fastener 371. The second clamping plate 373 is fixedly connected to the connecting seat 372. The second clamping plate 373 is provided with a second slot 3730, which is used for the edge of the second control plate 42 to be inserted.

[0096] In at least one embodiment, the third fastener 371 may be a bolt fastener.

[0097] A second threaded hole can be opened at the end of the connecting seat 372 in the extension direction, and a third fastener 371 is inserted into the second threaded hole of the second slide rail structure 22 and the connecting seat 372 to achieve a fixed connection between the connecting seat 372 and the second slide rail structure 22.

[0098] The connecting base 372 and the second clamping plate 373 can be integrated into one piece. The second clamping plate 373 can be fixed to the upper part of the connecting base 372, so that the top of the second clamping plate 373 is higher than the height of the connecting base 372. The second clamping plate 373 is used to clamp the second control board 42. Therefore, the second control board 42 is above the first control board 41. There is a gap between the second control board 42 and the first control board 41. This not only allows for quick electrical connection between the two through a ribbon cable, but also meets certain insulation distance requirements, reducing the probability of short circuit faults.

[0099] The second clamping plate 373 is provided with a second slot 3730. The width of the second slot 3730 is greater than or equal to the edge thickness of the second control plate 42, so as to ensure that the edge of the second control plate 42 can be smoothly inserted into the second slot 3730 of the second clamping plate 373.

[0100] In some embodiments, combined with Figure 6 As shown, the second slide rail structure 22 is provided with a third adjustment hole 220, the third adjustment hole 220 extends along the first direction, and the third fastener 371 passes through the third adjustment hole 220 and the connecting seat 372.

[0101] In at least one embodiment, the extending direction of the second slide rail structure 22 is parallel to the extending direction of the third adjusting hole 220, and both are along... Figure 6 The coordinate system extends along the X-axis. The third adjustment hole 220 can be a rectangular hole or an oblong hole.

[0102] When clamping second control plates 42 of different specifications, such as different lengths, the third fastener 371 can be loosened so that the second clamping part 37 moves relative to the connecting rod 35 in the first direction. At this time, the third fastener 371 can move within the third adjustment hole 220 of the second slide rail structure 22 until the distance between the two second clamping parts 37 matches the length of the second control plate 42. Then, the third fastener 371 is tightened to achieve the clamping and fixing operation of the second control plate 42 by fastening the position of the second clamping part 37 and the second slide rail structure 22.

[0103] In some embodiments, combined with Figure 6 As shown, the second card slot 3730 gradually widens from the end away from the second control board 42 to the end of the second card slot 3730 closer to the second control board 42.

[0104] In at least one embodiment, the gradual widening of the second slot 3730 from the end away from the second control board 42 to the end near the second control board 42 means that the width of the second slot 3730 at the end away from the second control board 42 is greater than the width of the second slot 3730 at the end near the second control board 42, and the width of the second slot 3730 gradually increases from the end away from the second control board 42 to the end near the second control board 42. The end shape of the second slot 3730 along the second direction may be a V-shaped structure.

[0105] Since the second slot 3730 gradually expands in size from the end away from the second control plate 42 to the end near the second control plate 42, the second clamping part 37 can move relative to the connecting rod 35 in the first direction. During the process of fixing the second control plate 42, the edge of the second control plate 42 is inserted into different positions of the second slot 3730, which is suitable for clamping and fixing operations of second control plates 42 of different thicknesses.

[0106] In some embodiments, combined with Figure 5 and Figure 6 As shown, the connecting rod 35 further includes a second cylindrical portion 352, which is fixedly connected to the connecting rod body 351; the clamping assembly 3 further includes a connecting shaft 34, which passes through the end of the fixed seat 31 away from the first slide rail structure 21 and the second cylindrical portion 352, and the second cylindrical portion 352 is used to rotate relative to the fixed seat 31 about the axis of the connecting shaft 34.

[0107] In at least one embodiment, the connecting shaft 34 can be inserted into the connecting rod 35 in the following manner: for example, the connecting rod 35 further includes a second cylindrical portion 352, which is fixedly connected to the connecting rod body 351. The connecting shaft 34 is inserted into the end of the fixed seat 31 away from the first slide rail structure 21, the first cylindrical portion 333 of the first clamping portion 33, and the second cylindrical portion 352 of the connecting rod 35. Therefore, the cooperation between the first cylindrical portion 333, the second cylindrical portion 352, and the connecting shaft 34 can realize the disassembly and assembly of the first clamping portion 33, the second clamping portion 37, and the fixed seat 31.

[0108] Since the connecting shaft 34 passes through the end of the fixed seat 31 away from the first slide rail structure 21 and the second cylindrical part 352 of the connecting rod 35, the second cylindrical part 352 is fixedly connected to the connecting rod body 351, and the connecting rod body 351 is connected to the second clamping part 37 through the second slide rail structure 22, so that the connecting rod 35 can drive the second slide rail structure 22, the second clamping part 37 and the second control plate 42 to rotate around the connecting shaft 34 relative to the fixed seat 31, thereby realizing the adjustment of the installation angle of the second control plate 42.

[0109] In some embodiments, combined with Figure 6 As shown, the connecting rod 35 also includes a plurality of limiting structures 353, which are fixed at intervals to the second cylindrical part 352, and the fixing seat 31 is located between two adjacent limiting structures 353.

[0110] In at least one embodiment, such as Figure 6As shown, two limiting structures 353 can be fixedly installed on the second cylindrical portion 352 of each connecting rod 35. For example, the limiting structures 353 are fixed to the circumferential sidewall of the second cylindrical portion 352, and the fixing seat 31 can be located between the two second limiting structures 353. The limiting structure 353 can be at least one of the following: rod-shaped structure, block-shaped structure, plate-shaped structure, etc. The limiting structure 353 and the second cylindrical portion 352 can be integrated into a single structure by welding, bonding, integral molding, or other methods.

[0111] Since the fixed seat 31 is located between the two limiting structures 353 provided on the outer wall of the second cylinder part 352, the limiting structure 353 can also abut against the fixed seat 31 while the second clamping part 37 rotates relative to the fixed seat 31 around the connecting shaft 34 to adjust the installation angle of the second control plate 42, so as to lock the position of the connecting rod 35 connected to the second clamping part 37 after rotation.

[0113] In some embodiments, combined with Figure 1 and Figure 8 As shown, the mounting base 1 is provided with a mounting groove and an open end communicating with the mounting groove, and the control plate structure 4 is used to be placed into the mounting groove from the open end.

[0114] In at least one embodiment, the mounting base 1 has a mounting groove and an open end, the open end being in communication with the mounting groove, and the control board structure 4 being able to be placed or removed from the open end into the mounting groove.

[0115] Because the mounting slot of the mounting base 1 extends outward, it creates internal space for mounting the sliding device 2, the clamping device, and the control plate structure 4. At least a portion of the control plate structure 4 is located within the receiving cavity. Figure 8 As shown.
