[0039] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0040] According to an embodiment of the present utility model, on the one hand, a support structure is provided for fixing a BMS module 1, and the support structure includes:

[0041] The base 2 extends along an X direction, wherein the X direction is parallel to a length direction of the BMS module 1;

[0042] A connecting member 5, fixedly connected to at least one end of the BMS module 1 along the X direction;

[0043] At least one side support block 3 is arranged in one-to-one correspondence with the connecting member 5, and the side support block 3 is arranged on a side of the connecting member 5 away from the BMS module 1 along the X direction; the side support block 3 is detachably connected to the base 2, and the side support block 3 is suitable for moving relative to the base 2 along the X direction;

[0044] The side support block 3 is provided with a disassembly guide groove 33, and the connecting member 5 is suitable for sliding along the disassembly guide groove 33; and a first quick-release member is provided on one of the connecting member 5 and the side support block 3, and a second quick-release member is provided on the other, and the connecting member 5 and the side support block 3 are connected via the first quick-release member and the second quick-release member.

[0045] The base 2 may be an independent structure, and is fixedly connected to the battery pack box by bolts or other connectors; as a variant, the base 2 may also be a part of the battery pack box. In this embodiment, a plurality of positioning holes are provided on the base 2, and the base 2 is fixedly connected to the battery pack by bolts.

[0046] The BMS module 1 can have various shapes. Figure 1 Taking the state of the BMS module 1 shown as an example, in this embodiment, the length direction of the BMS module 1 is parallel to the X direction, the width direction of the BMS module 1 is parallel to the Y direction, and the thickness direction of the BMS module 1 is parallel to the Z direction.

[0047] A connector 5 is fixed to at least one end of the BMS module 1 along the X direction. Figure 5 As shown, the connector 5 includes a connector block body 54, which is fixedly connected to the end surface of one side of the BMS module 1 along the length direction through a locking member 52. The same connector block body 54 is fixedly connected to the BMS module 1 via at least two locking members 52.

[0048] At least one side support block 3 is arranged in one-to-one correspondence with the connecting member 5. By connecting the connecting member 5 with the side support block 3, the BMS module 1 can be fixed on the side support block 3. Since the side support block 3 is movably connected with the base 2, the side support block 3 is suitable for moving relative to the base 2 along the X direction, so that the BMS module 1 can be moved relative to the base 2 along the X direction. Therefore, the fixed position of the side support block 3 on the base 2 can be reasonably adjusted according to the length of the BMS module 1 to adapt to BMS modules 1 of different lengths.

[0049] The side support block 3 is provided with a disassembly guide groove 33, and the connecting member 5 is suitable for sliding along the disassembly guide groove 33, so that the BMS module 1 can be moved relative to the side support block 3 along the Y direction; Figure 1 Taking the state of the BMS module 1 and the side support block 3 as an example, the disassembly guide groove 33 can extend along the Y direction, and at this time, the BMS module 1 is suitable for moving along the Y direction relative to the side support block 3. Therefore, the fixed position of the BMS module 1 on the side support block 3 can be reasonably adjusted according to the width of the BMS module 1 to adapt to BMS modules 1 of different widths.

[0050] At the same time, since the connector 5 is fixed on the BMS module 1 and the BMS module 1 has no interference with the side support block 3 along the Z direction, by reasonably setting the fixed position of the connector 5 on the BMS module 1, it can adapt to BMS modules 1 of different thicknesses.

[0051] The bracket structure provided in the embodiment of the utility model can fix the BMS module 1 on the side support block 3 by connecting the connecting piece 5 with the side support block 3, and because the side support block 3 is movably connected with the base 2, the side support block 3 is suitable for moving relative to the base 2 along the X direction, so that the BMS module 1 can move relative to the base 2 along the X direction; the side support block 3 is provided with a disassembly guide groove 33, and the connecting piece 5 is suitable for sliding along the disassembly guide groove 33, so that the BMS module 1 can move relative to the side support block 3 along the Y direction; and the BMS module 1 has no interference with the side support block 3 along the Z direction, so that the bracket structure provided in the embodiment of the utility model can adapt to BMS modules 1 of different lengths, widths and thicknesses, achieve dimensional compatibility in the three directions of XYZ, meet the installation requirements of BMS modules of different specifications, improve the redundancy of the size of the BMS module 1 in the development process of the power battery, reduce the risk of secondary development, and reduce the development cost. At the same time, a first quick-release part is provided on one of the connecting member 5 and the side support block 3, and a second quick-release part is provided on the other, which can realize quick disassembly and quick installation of the connecting member 5 and the side support block 3, reduce the complexity of installation, facilitate later maintenance, and improve the maintenance efficiency of the BMS module 1.

[0052] Combination Figure 1 As shown, when the BMS module 1 is in a vertical state, the projection of the BMS module 1 along the Y direction does not overlap with the projection of the side support block 3. By setting the wiring harness of the BMS module 1 on the end surface away from the base 2 along the Y direction, the risk of interference of the support structure with the wiring harness of the BMS module 1 can be reduced. Similarly, when the BMS module 1 is in a horizontal state, the projection of the BMS module 1 along the Z direction does not overlap with the projection of the side support block 3. By setting the wiring harness of the BMS module 1 on the end surface away from the base 2 along the Z direction, the risk of interference of the support structure with the wiring harness of the BMS module 1 can be reduced.

[0053] In some embodiments, in combination Figure 2 , Figure 3 As shown, the side support block 3 is provided with a plurality of fixing holes 31 spaced apart along the extension direction of the disassembly and assembly guide groove 33, and the connecting member 5 is provided with a fixing pin 51, which is suitable for sliding along the disassembly and assembly guide groove 33 and for extending into the fixing hole 31 to realize the connection between the connecting member 5 and the side support block 3.

[0054] In some embodiments, in combination Figure 4 , Figure 5 As shown, the connecting member 5 further includes a connecting block body 54 and an elastic member 53 . The connecting block body 54 is provided with a mounting hole, and the fixing pin 51 is telescopically mounted in the mounting hole of the connecting block body 54 via the elastic member 53 .

[0055] The disassembly guide groove 33 is arranged on a side of the side support block 3 facing the connecting member 5 .

[0056] Taking the BMS module 1 in a vertical state as an example, the upper end of the disassembly and assembly guide groove 33 along the Y direction forms an entry and exit port 331, and the fixing pin 51 slides into the disassembly and assembly guide groove 33 from the entry and exit port 331. The fixing pin 51 slides along the disassembly and assembly guide groove 33. When the BMS module 1 moves to the desired position, the fixing pin 51 is moved along the Z direction so that the fixing pin 51 slides into the fixing hole 31. Due to the elastic force of the elastic member 53, the fixing pin 51 and the fixing hole 31 can be kept in a clamping state, so as to achieve the fixation of the connecting member 5 and the side support block 3.

[0057] By providing connectors 5 on both sides of the BMS module 1 along the X direction and providing fixing pins 51 on the connectors 5 on both sides, the BMS module 1 can be quickly fixed to the side support blocks 3 on both sides, thereby realizing the quick disassembly and quick installation functions of the BMS module 1.

[0058] At least two fixing pins 51 are disposed on the connecting member 5 , and the spacing between adjacent fixing pins 51 corresponds to the spacing between adjacent fixing holes 31 .

[0059] When the thickness of the BMS module 1 changes, as long as there are bolt holes corresponding to the connectors 5 on both sides of the BMS module 1 along the X direction, the BMS module 1 can be installed on the side support blocks 3 on both sides through the connectors 5 .

[0060] In addition, taking the BMS module 1 in a vertical state as an example, if the BMS module 1 is too large in thickness direction, that is, Figure 1 The Z-direction dimension of the BMS module 1 shown in the figure is too large, and the BMS module 1 can be fixed by installing two or more bracket structures side by side in the Z-direction.

[0061] Taking the BMS module 1 in a vertical state as an example, the quick disassembly process of the BMS module 1 is as follows:

[0062] Press the fixing pins 51 on the connecting members 5 on both sides to disengage the fixing pins 51 from the fixing holes 31 on the side support blocks 3, and apply force along the Z direction to make the fixing pins 51 slide into the disassembly guide grooves 33. Move along the extension direction of the disassembly guide grooves 33 to pull the BMS module 1 and the connecting member 5 out of the bracket structure, thereby completing the disassembly of the BMS module 1.

[0063] Similarly, the quick installation process of the BMS module 1 is as follows: press the fixing pins 51 on the connecting parts 5 on both sides, align the fixing pins 51 with the disassembly and assembly guide grooves 33, and move the fixing pins 51 along the extension direction of the disassembly and assembly guide grooves 33. When the BMS module 1 moves to the desired position, apply force along the Z direction to make the fixing pins 51 rebound in the fixing holes 31, thereby completing the installation and fixation of the BMS module 1.

[0064] The quick disassembly and quick assembly process of the BMS module 1 in the horizontal state is the same as that in the vertical state, and will not be repeated here.

[0065] In some embodiments, in combination Figure 2 , Figure 3 As shown, the support structure also includes a limiting component 4 connected to the side support block 3, and a first slider is provided on one of the limiting component 4 and the base 2, and a first slide track is opened along the X direction on the other. For example, a first slider 41 is provided on the limiting component 4, and a first slide track 21 is opened along the X direction on the base 2, and the limiting component 4 and the base 2 are slidably connected with the first slide track 21 via the first slider 41.

[0066] In this embodiment, a first sliding block 41 is disposed on the limiting assembly 4, and a first slideway 21 is formed on the base 2 along the X direction.

[0067] The first sliding block 41 may specifically be a T-shaped nut.

[0068] By sliding the limiting assembly 4 on the base 2, the relative position of the side support block 3 and the base 2 along the X direction can be adjusted, thereby adjusting the distance between the two relatively arranged side support blocks 3 to achieve compatibility with the dimensional changes in the length direction of the BMS module 1.

[0069] In some embodiments, in combination Figure 4 As shown, the limit assembly 4 includes a limit block body 44, and the first slider 41 is connected to the limit block body 44 via a first elastic member 43. The first elastic member 43 has a locking state that locks the first slider 41 and the first slide 21, and a loosening state that allows the first slider 41 to slide relative to the first slide 21.

[0070] By loosening the first elastic member 43 , the first slide block 41 can slide relative to the first slideway 21 , thereby facilitating adjustment of the relative position of the limit block body 44 and the base 2 , that is, adjusting the relative position of the side support block 3 and the base 2 .

[0071] By tightening the first elastic member 43 , the first sliding block 41 is locked and connected to the first slideway 21 , thereby fixing the limit block body 44 at a preset position of the base 2 .

[0072] In some embodiments, in combination Figure 3 As shown, one of the limiting assembly 4 and the side support block 3 is provided with a second sliding block 42 , and the other is provided with a second slideway 32 .

[0073] In this embodiment, a second slider 42 is provided on the limit assembly 4, and a second slideway 32 is provided on the side support block 3; when the BMS module 1 is in a vertical state, the extension direction of the second slideway 32 is parallel to the Y direction. When the BMS module 1 is in a horizontal state, the extension direction of the second slideway 32 is parallel to the Z direction.

[0074] The second sliding block 42 may specifically be a T-shaped nut.

[0075] By making the side support block 3 suitable for sliding relative to the limiting assembly 4 along the extension direction of the second slideway 32, the fixed positions of the side support block 3 and the limiting assembly 4 can be reasonably adjusted according to the width of the BMS module 1 to adapt to BMS modules 1 of different widths.

[0076] In some embodiments, in combination Figure 4 As shown, the limit assembly 4 includes a limit block body 44, and the second slider 42 is connected to the limit block body 44 via a second elastic member 45. The second elastic member 45 has a locking state in which the second slider 42 is locked and connected to the second slideway 32, and a loosening state in which the second slider 42 slides relative to the second slideway 32;

[0077] The side support block 3 is suitable for rotating around the axis of the second elastic member 45 to change the angle between the side support block 3 and the limit block body 44, wherein the axis of the second elastic member 45 is parallel to the X direction.

[0078] In this embodiment, combined with Figure 4 As shown, the axial direction of the first elastic member 43 is perpendicular to the axial direction of the second elastic member 45 .

[0079] By loosening the second elastic member 45 , the second slide block 42 can slide relative to the second slideway 32 , thereby facilitating the adjustment of the relative position of the side support block 3 and the limit block body 44 .

[0080] By tightening the second elastic member 45 , the second sliding block 42 is locked and connected to the second slideway 32 , thereby fixing the side support block 3 at a preset position of the limit block body 44 .

[0081] When the second tension piece 45 is in the loosened state, the side support block 3 is suitable for rotating around the second tension piece 45 to change the angle between the side support block 3 and the limit block body 44, thereby enabling the BMS module 1 to switch between the vertical state and the horizontal state.

[0082] The bracket structure provided in the embodiment of the utility model allows the side support block 3 to rotate around the second elastic member 45 to change the angle between the side support block 3 and the limit block body 44, so that the BMS module 1 can be switched between a vertical state and a horizontal state, thereby realizing the diversity of installation directions of the BMS module 1 in the battery pack, increasing the possibility of internal structure layout during the battery pack development process, and also improving the convenience of later maintenance of the BMS module 1.

[0083] In some embodiments, in combination Figure 2As shown, the base 2 is further provided with a scale 22 along the extension direction of the first slideway 21. By providing the scale 22 on the base 2, the side support block 3 can be easily adjusted so as to measure the distance between two side support blocks 3 arranged opposite to each other.

[0084] In some embodiments, connectors 5 are fixed at both ends of the BMS module 1 along the X direction, there are two side support blocks 3 , and the two side support blocks 3 are detachably connected to the base 2 .

[0085] According to an embodiment of the present invention, on the other hand, a battery pack is provided, including a BMS module 1 and a bracket structure for fixing the BMS module 1 as described above.

[0086] The battery pack provided by the embodiment of the utility model can fix the BMS module 1 on the side support block 3 by connecting the connecting piece 5 with the side support block 3, and because the side support block 3 is movably connected with the base 2, the side support block 3 is suitable for moving relative to the base 2 along the X direction, thereby enabling the BMS module 1 to move relative to the base 2 along the X direction; the side support block 3 is provided with a disassembly and assembly guide groove 33, and the connecting piece 5 is suitable for sliding along the disassembly and assembly guide groove 33, thereby enabling the BMS module 1 to move relative to the side support block 3; and the BMS module 1 has no interference with the side support block 3 along the Z direction, so that the bracket structure provided by the embodiment of the utility model can adapt to BMS modules 1 of different lengths, widths and thicknesses, achieve dimensional compatibility in the three directions of XYZ, meet the installation requirements of BMS modules of different specifications, improve the redundancy of the size of the BMS module 1 in the development process of the power battery, reduce the risk of secondary development, and reduce the development cost.
