[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0031] like Figures 1 to 3 As shown, the BMS bracket 10 of the embodiment of the utility model includes a mounting plate 1 and at least one first leg 21, and the first leg 21 is separately arranged from the mounting plate 1 and connected to the mounting plate 1. The mounting plate 1 has at least one control board mounting portion. The first leg 21 is separately arranged from the mounting plate 1, which can be understood as: the first leg 21 and the mounting plate 1 are separately processed and manufactured, that is, the first leg 21 and the mounting plate 1 are not integrally formed.

[0032] Among them, the BMS bracket 10 includes at least one first leg 21, which can be understood as: the BMS bracket 10 includes one first leg 21, or the BMS bracket 10 includes more than two first legs 21. When the BMS bracket 10 includes one first leg 21, the BMS bracket 10 can be supported and fixed in the battery pack only by one first leg 21, or it can be supported and fixed in the battery pack by the first leg 21 and other legs. When the BMS bracket 10 includes more than two first legs 21, the BMS bracket 10 can be supported and fixed in the battery pack only by more than two first legs 21, or it can be supported and fixed in the battery pack by more than two first legs 21 and other legs. In addition, more than two first legs 21 can be arranged on the same side of the width direction or length direction of the mounting plate 1 at the same time; they can also be arranged on both sides of the width direction or length direction of the mounting plate 1 respectively; they can also be arranged in part on one side of the width direction of the mounting plate 1, and the other part on one side of the length direction of the mounting plate 1.

[0033] The mounting plate 1 has at least one control panel mounting portion, which can be understood as: the mounting plate 1 has one control panel mounting portion, or the mounting plate 1 has more than two control panel mounting portions. When the mounting plate has one control panel mounting portion, the control panel mounting portion can be used to mount the BMS main control panel 20 or the BMS slave control panel 30, or the control panel mounting portion is used to mount both the BMS main control panel 20 and the BMS slave control panel 30; when the mounting plate has more than two control panel mounting portions, the BMS main control panel 20 and the BMS slave control panel 30 can be mounted on two different control panel mounting portions, respectively. For example, Figure 1 As shown, the mounting plate has two control panel mounting parts, which are respectively a master control mounting part 11 and a slave control mounting part. The BMS master control panel 20 is mounted on the master control mounting part 11, and the BMS slave control panel 30 is mounted on the slave control mounting part. The BMS master control panel 20 and the BMS slave control panel 30 are both control panels.

[0034] like Figure 1 As shown, when the BMS bracket 10 of the embodiment of the utility model is in use, the control board is installed on the control board installation part. By separating the first leg 21 from the mounting plate 1, the structure of the first leg 21 will not be restricted by the molding method of the mounting plate 1, so that the angle between the first leg 21 and the mounting plate 1 can be set smaller. In this way, the occupied space of the first leg 21 can be reduced, and then the occupied space of the BMS bracket 10 can be reduced.

[0035] Therefore, the BMS bracket 10 of the embodiment of the utility model has the advantages of occupying a small space.

[0036] In some embodiments, both surfaces of the mounting plate 1 in the thickness direction are provided with control board mounting portions.

[0037] For example, Figure 1 As shown, both the upper and lower surfaces of the mounting plate 1 are provided with control board mounting parts. The BMS main control board 20 is mounted on the control board mounting part provided on the upper surface of the mounting plate 1 , and the BMS slave control board 30 is mounted on the control board mounting part provided on the lower surface of the mounting plate 1 .

[0038] Therefore, integrating the control board mounting parts for the BMS main control board 20 and the BMS slave control board 30 on the same BMS bracket 10 is beneficial to further improve the integration of the BMS bracket 10, thereby further reducing the occupied space of the BMS bracket 10.

[0039] In some embodiments, Figures 1 to 3 As shown, the BMS bracket 10 further includes a second leg 22, which is integrally formed with the mounting plate 1, and is disposed on at least one side in the length direction of the mounting plate 1, and the first leg 21 is disposed on at least one side in the width direction of the mounting plate 1. The second leg 22 and the mounting plate 1 can be integrally stamped, and the angle between the second leg 22 and the mounting plate 1 is an obtuse angle.

[0040] The second leg 22 is provided on at least one side in the length direction of the mounting plate 1, which can be understood as: the second leg 22 is provided on one side in the length direction of the mounting plate 1; or, the second leg 22 is provided on both sides in the length direction of the mounting plate 1. The first leg 21 is provided on at least one side in the width direction of the mounting plate 1, which can be understood as: the first leg 21 is provided on one side in the width direction of the mounting plate 1; or, the first leg 21 is provided on both sides in the width direction of the mounting plate 1.

[0041] It is understandable that inside the battery pack, the size requirements of the BMS bracket 10 in each direction may be different. Figure 4 As shown, the box body 40 of the battery pack includes a front crossbeam 401 and a front side beam 402, the first leg 21 is connected to the front crossbeam 401, and the second leg 22 is connected to the front side beam 402. The space in the box body 40 for installing the BMS bracket 10 is larger in the front-to-back direction and smaller in the left-to-right direction. The first leg 21 is arranged on the right side of the mounting plate 1, and the second leg 22 is arranged on the front side of the mounting plate 1, so that the size of the BMS bracket 10 in the left-to-right direction is smaller. Among them, the length direction of the mounting plate 1 is consistent with the front-to-back direction, and the width direction of the mounting plate 1 is consistent with the left-to-right direction.

[0042] The second leg 22 is integrally formed with the mounting plate 1, which is conducive to simplifying the structure of the BMS bracket 10 and facilitating the processing and manufacturing of the BMS bracket 10. Thus, while ensuring that the size of the BMS bracket 10 in a certain direction is small, the processing and manufacturing of the BMS bracket 10 can be facilitated.

[0043] In other embodiments, the first leg 21 and the second leg 22 are arranged on the same side of the mounting plate 1 in the width direction; or, the first leg 21 and the second leg 22 are arranged on the same side of the mounting plate 1 in the length direction; or, the first leg 21 is arranged on at least one side of the mounting plate 1 in the length direction, and the second leg 22 is arranged on at least one side of the mounting plate 1 in the width direction. In addition, when there are multiple first legs 21, the multiple first legs 21 are arranged on the same side of the mounting plate 1 in the width direction, and the second legs 22 are arranged on one side of the mounting plate 1 in the length direction; or, the multiple first legs are arranged on the same side of the mounting plate 1 in the length direction, and the second legs 22 are arranged on one side of the mounting plate 1 in the width direction; or, a part of the first legs 21 are arranged on one side of the mounting plate 1 in the width direction, and another part of the first legs 21 and the second legs 22 are arranged on one side of the mounting plate 1 in the length direction; or, a part of the first legs 21 and the second legs 22 are arranged on one side of the mounting plate 1 in the width direction, and another part of the first legs 21 are arranged on one side of the mounting plate 1 in the length direction.

[0044] In some embodiments, the first leg 21 is extended along the thickness direction of the mounting plate 1 .

[0045] For example, the first leg 21 is arranged perpendicular to the plane where the mounting plate 1 is located.

[0046] For example, Figure 1 and Figure 4 As shown, the first leg 21 extends in the up-down direction, the upper end of the first leg 21 is connected to the mounting plate 1 , and the lower end of the first leg 21 is connected to the box body 40 of the battery pack.

[0047] The first leg 21 is extended along the thickness direction of the mounting plate 1, so that the angle between the first leg 21 and the mounting plate 1 is small. Thus, the space occupied by the first leg 21 can be further reduced, and the space occupied by the BMS bracket 10 can be further reduced.

[0048] In other embodiments, the angle between the first leg 21 and the mounting plate 1 may be an acute angle.

[0049] Optionally, the first leg 21 is a support column, one end of the first leg 21 in the extension direction is detachably connected to the mounting plate 1 , and a thread 211 is provided on the outer peripheral surface of the first leg 21 .

[0050] The outer circumference of the first leg 21 is provided with threads 211, which means that the outer circumference of the first leg 21 is entirely provided with threads 211, or the outer circumference of the first leg 21 is partially provided with threads 211. When the outer circumference of the first leg 21 is partially provided with threads 211, a section of the first leg 21 away from the mounting plate 1 in the thickness direction of the mounting plate 1 is provided with threads 211; and a section of the first leg 21 close to the mounting plate 1 in the thickness direction of the mounting plate 1 is not provided with threads.

[0051] For example, Figure 1 As shown, the upper end of the first leg 21 is detachably connected to the mounting plate 1 by screws. The lower section of the first leg 21 is provided with a thread 211, and the front cross beam 401 is provided with a first threaded hole, and the thread 211 is threadedly connected with the first threaded hole.

[0052] Therefore, when installing the BMS bracket 10, the first leg 21 can be firstly threadedly connected to the box body 40 (such as the front crossbeam 401) of the battery pack, and then the mounting plate 1 can be connected to the first leg 21. This facilitates the installation and fixation of the BMS bracket 10.

[0053] In other embodiments, a buckle may also be provided at the end of the first leg 21 away from the mounting plate 1 , so that the first leg 21 is buckled with the box body 40 of the battery pack.

[0054] like Figures 1 to 3 As shown, a second connecting hole 221 is provided at the bottom of the second supporting leg 22, and a second threaded hole is provided at the front side beam 402. A screw passes through the second connecting hole 221 and is threadedly connected with the second threaded hole.

[0055] Optionally, the main control mounting part 11 is provided with a first stud 111, and the BMS main control board 20 is provided with a first through hole for the first stud 111 to pass through. The slave control mounting part is provided with a second stud 121, and the BMS slave control board 30 is provided with a second through hole for the second stud 121 to pass through.

[0056] For example, the main control mounting portion 11 is arranged on the upper side of the slave control mounting portion, the first stud 111 is arranged to protrude upward from the mounting plate 1, and the second stud 121 is arranged to protrude downward from the mounting plate 1. The up-down direction is consistent with the thickness direction of the mounting plate 1.

[0057] When installing the BMS main control board 20 and the BMS slave control board 30, the first stud 111 passes through the first through hole of the BMS main control board 20 and is threadedly connected to the nut to achieve the connection between the BMS main control board 20 and the BMS bracket 10; the second stud 121 passes through the second through hole of the BMS slave control board 30 and is threadedly connected to the nut to achieve the connection between the BMS slave control board 30 and the BMS bracket 10.

[0058] Optionally, a first stud hole 112 and a second stud hole 122 are provided on the mounting plate 1 , the first stud 111 passes through the first stud hole 112 and is welded to the hole wall of the first stud hole 112 , and the second stud 121 passes through the second stud hole 122 and is welded to the hole wall of the second stud hole 122 .

[0059] In some embodiments, Figures 1 to 3 As shown, a lug plate 13 is provided at the edge of the mounting plate 1 , and the first leg 21 is detachably connected to the lug plate 13 .

[0060] For example, the ear plate 13 is arranged on one side in the width direction of the mounting plate 1, the first leg 21 is arranged on the lower side of the ear plate 13, the ear plate 13 is provided with an ear plate hole passing through in the up and down directions, the first leg 21 is provided with a third threaded hole opening in a certain direction, a screw passes through the ear plate hole and is threadedly connected with the third threaded hole, thereby realizing a detachable connection between the first leg 21 and the ear plate 13.

[0061] By connecting the first leg 21 to the ear plate 13 , the connection area between the first leg 21 and the mounting plate 1 is increased, thereby improving the connection reliability between the first leg 21 and the mounting plate 1 , which is beneficial to improving the reliability of the BMS bracket 10 .

[0062] Of course, in other embodiments, the first leg 21 and the ear plate 13 may also be connected by snap fastening or bonding.

[0063] Optionally, the BMS bracket 10 further includes a harness buckle 3, the harness buckle 3 includes a clamping joint 31 and a harness hole 32, and the clamping joint 31 of the harness buckle 3 is clamped with the ear plate 13. The number of the harness buckles 3 may be 1 to 4; the harness buckle 3 may be a cable tie type harness buckle, that is, the harness buckle 3 includes a cable tie, and the cable tie surrounds the harness hole 32.

[0064] For example, the clamping joint 31 of the harness clamp 3 can be a fir tree clamp or a sheet metal clamp. The ear plate 13 is provided with a clamping hole 1312 , and the clamping joint 31 is clamped with the clamping hole 1312 .

[0065] The harness hole 32 of the harness buckle 3 is used to fix the electrical harness, so as to fix the electrical harness inside the battery pack. The harness buckle 3 is connected to the ear plate 13, so that the ear plate 13 not only has the function of connecting with the first leg 21, but also integrates the function of fixing the harness buckle 3, which is conducive to improving the integration of the BMS bracket 10, thereby further reducing the occupied space of the BMS bracket 10.

[0066] Alternatively, if Figures 1 to 3 As shown, there are two wire harness buckles 3, which are a first wire harness buckle 301 and a second wire harness buckle 302. The clamping joint 31 of the first wire harness buckle 301 is a fir buckle, and the clamping joint 31 of the second wire harness buckle 302 is a sheet metal buckle.

[0067] Alternatively, if Figure 2 and Figure 3 As shown, a flange 133 is provided at the edge of the ear plate 13 , and the flange 133 and the first leg 21 are provided on the same side of the ear plate 13 in the thickness direction of the mounting plate 1 .

[0068] For example, Figure 1 and Figure 2As shown, the first leg 21 is arranged on the lower side of the ear plate 13 , and the edge of the ear plate 13 is provided with a downward flange 133 .

[0069] The provision of the flange 133 can also improve the structural strength of the ear plate 13 , thereby improving the structural strength of the BMS bracket 10 and improving the reliability of the BMS bracket 10 .

[0070] Optionally, the harness buckle 3 and the first leg 21 are arranged opposite to each other on two sides of the ear plate 13 in the thickness direction of the mounting plate 1 .

[0071] For example, Figure 1 and Figure 2 As shown, the first leg 21 is disposed on the lower side of the ear plate 13 , and the first harness buckle 301 is disposed on the upper side of the ear plate 13 .

[0072] By arranging the harness buckle 3 and the first leg 21 on two different sides of the ear plate 13, it is possible to avoid interference between the harness buckle 3 and the first leg 21, and to facilitate fixing the harness on the harness buckle 3. In addition, when the flange 133 and the first leg 21 are arranged on the same side of the ear plate 13, when an electrical harness is fixed on the harness buckle 3, it is possible to avoid the edge of the ear plate 13 from abrading the electrical harness, which is beneficial to improving the safety and reliability of the battery pack.

[0073] Alternatively, if Figure 2 and Figure 3 As shown, the ear plate 13 includes a first portion 131 and a second portion 132 connected to each other, the first portion 131 is smoothly connected to the mounting plate 1, and the second portion 132 extends along the thickness direction of the mounting plate 1. The first leg 21 is connected to the first portion 131, and the number of the wire harness buckles 3 is multiple, wherein a part of the wire harness buckles 3 is clamped to the first portion 131, and another part of the wire harness buckles 3 is clamped to the second portion 132.

[0074] For example, Figure 1 and Figure 2 As shown, the first wire harness buckle 301 is buckled with the first part 131 , and the second wire harness buckle 302 is buckled with the second part 132 .

[0075] By setting the ear plate 13 to the above structure, at least two harness buckles 3 can be fixed on the ear plate 13, which is beneficial to further improve the integration of the BMS bracket 10, thereby further reducing the occupied space of the BMS bracket 10.

[0076] Alternatively, if Figure 3As shown, the first part 131 is provided with a first connection hole 1311 and a clamping hole 1312, and the first connection hole 1311 is arranged closer to the mounting plate 1 than the clamping hole 1312. The first leg 21 is provided with a fixing hole, which is aligned with the first connection hole 1311. The screw passes through the first connection hole 1311 and is threadedly connected with the fixing hole to realize the connection between the first leg 21 and the ear plate 13; the clamping joint 31 of the first harness buckle 301 is clamped with the clamping hole 1312.

[0077] For example, Figure 3 As shown, the ear plate 13 is arranged on the right side of the mounting plate 1 , and the first connecting hole 1311 is arranged on the left side of the clamping hole 1312 , so that the first leg 21 is arranged on the left side of the first wire harness buckle 301 .

[0078] Therefore, the first leg 21 is disposed closer to the mounting plate 1 , which is beneficial to further reduce the occupied space of the BMS bracket 10 .

[0079] Alternatively, if Figure 2 and Figure 3 As shown, the mounting plate 1 has at least one hollow portion 14. The hollow portion 14 is formed by hollowing out a portion of the mounting plate 1.

[0080] The mounting plate 1 has at least one hollow portion 14, which means that the mounting plate 1 has only one hollow portion 14, and the hollow portion 14 is located in the middle of the mounting plate 1; or the mounting plate 1 has more than two hollow portions 14. Figure 2 and Figure 3 As shown, the mounting plate 1 has two hollow portions 14, and the two hollow portions 14 are arranged at intervals along the length direction of the mounting plate 1, so that the mounting plate 1 forms a structure including two first beams and three second beams, wherein the first beam extends along the length direction of the mounting plate 1, and the two first beams are arranged at intervals along the width direction of the mounting plate 1; the second beam extends along the width direction of the mounting plate 1, and the three second beams are arranged at intervals along the length direction of the mounting plate 1.

[0081] By providing the hollow portion 14 on the mounting plate 1 , the weight and material cost of the mounting plate 1 can be reduced, thereby reducing the cost of the BMS bracket 10 .

[0082] Optionally, the mounting plate 1 has at least one recessed portion 15, which is recessed along the thickness direction of the mounting plate 1. The mounting plate 1 may be a sheet metal part with a thickness greater than or equal to 1 mm, and the recessed portion 15 is formed by stamping a portion of the mounting plate 1 downward.

[0083] The mounting plate 1 having at least one recessed portion 15 means that the mounting plate 1 has only one recessed portion 15; or the mounting plate 1 has more than two recessed portions 15. For example, the mounting plate 1 includes two first beams and three second beams, wherein the first beams extend along the length direction of the mounting plate 1, and the two first beams are arranged at intervals along the width direction of the mounting plate 1; the second beams extend along the width direction of the mounting plate 1, and the three second beams are arranged at intervals along the length direction of the mounting plate 1.
