DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Figure 1 It is a schematic diagram of the overall structure provided by an embodiment of the utility model; Figure 2 Schematic diagram of the support structure provided by the embodiment of the utility model. Figure 1 and Figure 2 A BMS fixing bracket structure shown includes a box body 1 and a BMS module 2, and also includes: a bracket 3, the bracket 3 includes a first mounting plate 31 and a second mounting plate 32, the first mounting plate 31 is perpendicular to the second mounting plate 32, and a first reinforcing rib 33 is arranged at the angle between the first mounting plate 31 and the second mounting plate 32, the bracket 3 is arranged on the top of the box body 1, the first mounting plate 31 is connected to the box body 1, and the second mounting plate 32 is connected to the BMS module 2.

[0023] For example, in the embodiment of the present utility model, Figure 1 As shown, the BMS module 2 is square, and correspondingly, the first mounting plate 31 and the second mounting plate 32 are also square, and a mounting hole is opened on the second mounting plate 32, and the BMS module 2 is fixed to the second mounting plate 32 through the mounting hole. The first mounting plate 31 and the second mounting plate 32 are made of 1.2mm thick steel. Compared with the 1.5mm thick steel used in the traditional technology, this bracket structure achieves the goal of lightweight. The first reinforcing rib 33 can be formed by adding welding material at the angle between the first mounting plate 31 and the second mounting plate 32, and then welding the first mounting plate 31, the second mounting plate 32 and the welding material together to form the first reinforcing rib 33. It can also be formed by pressing the angle between the first mounting plate 31 and the second mounting plate 32 inward by external force from the outside of the connection between the first mounting plate 31 and the second mounting plate 32. By providing a first reinforcing rib 33 at the angle between the first mounting plate 31 and the second mounting plate 32, the structural strength between the first mounting plate 31 and the second mounting plate 32 is strengthened, so that when the BMS module 2 is installed on the second mounting plate 32, the first mounting plate 31 and the second mounting plate 32 will not collapse due to the excessive weight of the BMS module 2, thereby enhancing the stability of the bracket structure. Compared with the box structure composed of five surfaces of the bracket in the conventional technology, the bracket structure composed of the first mounting plate 31 and the second mounting plate 32 is adopted in the embodiment of the utility model, thereby reducing the overall weight of the bracket structure. At the same time, by providing the first reinforcing rib 33, the stability of the bracket structure is enhanced.

[0024] The embodiment of the utility model provides a BMS fixed bracket structure, which is provided with a first mounting plate 31 and a second mounting plate 32 to form a main body of the bracket structure. A first reinforcing rib 33 is provided at the connection between the first mounting plate 31 and the second mounting plate 32. The first reinforcing rib 33 is used to strengthen the structural strength between the first mounting plate 31 and the second mounting plate 32, so that the main body of the bracket structure can still maintain a high structural strength when there are only the first mounting plate 31 and the second mounting plate 32, thereby effectively solving the problem of complex main structure and heavy weight in the prior art.

[0025] Optionally, a plurality of first reinforcing ribs 33 are provided, and the plurality of first reinforcing ribs 33 are evenly spaced along a junction line between the first mounting plate 31 and the second mounting plate 32 .

[0026] Exemplarily, in the embodiment of the utility model, by providing a plurality of first reinforcing ribs 33, the structural strength between the first mounting plate 31 and the second mounting plate 32 is made higher, and by evenly arranging the first reinforcing ribs 33, the first reinforcing ribs 33 are made more uniform when subjected to force, thereby further improving the stability of the fixed bracket structure.

[0027] Optionally, a weight-reducing groove 34 is formed on the second mounting plate 32 , and the BMS module 2 covers the weight-reducing groove 34 .

[0028] Exemplarily, in an embodiment of the utility model, a weight-reducing groove 34 is provided on the second mounting plate 32, which further reduces the weight of the main body of the bracket structure. By providing the weight-reducing groove 34, it is convenient to plug in the wires and signal lines of the BMS module 2 through the weight-reducing groove 34. The shape of the weight-reducing groove 34 matches the shape of the BMS module 2, and is also square in the present embodiment. The distance between the weight-reducing groove 34 and the edge of the second mounting plate 32 is 12 mm, so that when the BMS module 2 is installed on the second mounting plate 32, it has a certain structural strength. By providing the weight-reducing groove 34, the weight of the fixed bracket structure is reduced.

[0029] Optionally, a second reinforcing rib 35 is provided on the edge of the weight-reducing groove 34 , the reinforcing rib 35 is located on the opposite side of the BMS module 2 , and the second reinforcing rib 35 is perpendicular to the second mounting plate 32 .

[0030] Exemplarily, in the embodiment of the utility model, since the weight reducing groove 34 is square, the edge of the weight reducing groove 34 is also square, and second reinforcing ribs 35 are arranged at the four edges of the weight reducing groove 34, so that when the second mounting plate 32 is subjected to a bending force perpendicular to the direction of the second reinforcing rib 35, the second reinforcing rib 35 can provide a certain structural strength, so that the second mounting plate 32 is less likely to bend and deform due to external force, thereby further improving the stability of the fixed bracket structure.

[0031] Optionally, a first reinforcement edge 36 is disposed on the top of the second mounting plate 32 , and the first reinforcement edge 36 is perpendicular to the second mounting plate 32 .

[0032] Exemplarily, in an embodiment of the utility model, by providing a first reinforcing edge 36 on the top of the second mounting plate 32, when the second mounting plate 32 is subjected to a bending force perpendicular to the direction of the first reinforcing edge 36, the first reinforcing edge 36 can provide a certain structural strength, so that the second mounting plate 32 is less likely to bend and deform due to external force, thereby further improving the stability of the fixed bracket structure.

[0033] Optionally, a wire binding hole 37 is provided on the first reinforcement edge 36 .

[0034] Exemplarily, in an embodiment of the utility model, a wire tie hole 37 is provided on the first reinforcement edge 36, and the wire tie hole 37 is used to prevent a tie base, so that the wires and signal lines connected to the BMS module 2 can be fixed by the tie base on the wire tie hole 37, and finally the wires and signal lines on the BMS are bundled, preventing the loose wires and signal lines from interfering with other components, thereby improving the practicality of the fixed bracket structure.

[0035] Optionally, second reinforcement edges 38 are provided on both side edges of the second mounting plate 32 , and the second reinforcement edges 38 are perpendicular to the second mounting plate 32 .

[0036] For example, in the example of the utility model, by providing second reinforcing edges 38 on both side edges of the second mounting plate 32, when the second mounting plate 32 is subjected to a bending force perpendicular to the direction of the second reinforcing edges 38, the second reinforcing edges 38 can provide a certain structural strength, so that the second mounting plate 32 is less likely to bend and deform due to external force, thereby further improving the stability of the fixed bracket structure.

[0037] Optionally, third reinforcement edges 39 are provided on both side edges of the first mounting plate 31 , and the third reinforcement edges 39 are perpendicular to the first mounting plate 31 .

[0038] Exemplarily, in the example of the utility model, by providing a third reinforcing edge 39 on both side edges of the first mounting plate 31, when the first mounting plate 31 is subjected to a bending force perpendicular to the direction of the third reinforcing edge 39, the third reinforcing edge 39 can provide a certain structural strength, so that the first mounting plate 31 is less likely to bend and deform due to external force, thereby further improving the stability of the fixed bracket structure.

[0039] Exemplarily, in the embodiment of the utility model, the length of the first mounting plate 31 and the second mounting plate 32 are both 200 mm, and the widths of the first reinforcing rib 33, the second reinforcing rib 35, the first reinforcing edge 36, the second reinforcing edge 38 and the third reinforcing edge 39 are all 2 mm. When the length of the first mounting plate 31 and the second mounting plate 32 is 400 mm, the widths of the first reinforcing rib 33, the second reinforcing rib 35, the first reinforcing edge 36, the second reinforcing edge 38 and the third reinforcing edge 39 are all 4 mm, that is, the ratio of the length of the first mounting plate 31 and the second mounting plate 32 to the width of the first reinforcing rib 33, the second reinforcing rib 35, the first reinforcing edge 36, the second reinforcing edge 38 and the third reinforcing edge 39 is 100:1. The first reinforcing rib 33, the second reinforcing rib 35, the first reinforcing edge 36, the second reinforcing edge 38 and the third reinforcing edge 39 constructed in this way can still improve the structural strength of the first mounting plate 31 and the second mounting plate 32 while using the least material, thereby solving the problem of heavy weight and relatively simple structure in the prior art.
