[0031] like Figure 1-2 As shown, a liquid-cooled battery pack bracket for energy storage includes: a frame body 1, a movable bracket 2 and a bottom bracket 3. The movable bracket 2 is arranged on the frame body 1 for supporting the battery pack, and the bottom bracket 3 is arranged on the frame body 1 for supporting the movable bracket 2.

[0032] The movable bracket 2 includes a supporting plate 21, a mounting plate 22 and a guide device 23. The mounting plate 22 is connected to the frame body 1. The supporting plate 21 is connected to the mounting plate 22 and is used to support the battery pack. The guide device 23 is arranged on the mounting plate 22 and is used to provide guidance for the removal of the battery pack.

[0033] In the present disclosure, the guide device 23 can provide guidance for the installation of the battery pack, and can quickly install the battery pack on the battery pack bracket, avoiding collision of the battery pack due to loading and unloading angles and improving installation efficiency.

[0034] In some embodiments, the guiding inclination angle of the guiding device 23 is 30°. Specifically, the guiding device 23 includes an abutting surface 231 and a first guiding surface 232 and a second guiding surface 233 arranged on both sides of the abutting surface 231. When the battery pack is installed, the abutting surface 231 contacts the battery pack, the first guiding surface 232 is used for guiding when the battery pack is installed, and the second guiding surface 233 is used for guiding when the battery pack is pulled out, so as to achieve the effect of quickly installing or removing the battery pack. It can be understood that the guiding inclination angle includes but is not limited to 30°, and can be set according to actual needs.

[0035] In some embodiments, the guide device 23 includes a sheet metal guide frame.

[0036] Specifically, multiple sets of sheet metal guide frames are welded on the side of the movable bracket 2, and the guide inclination angle of the sheet metal guide frame is 30°. A stainless steel internal threaded round head cylindrical pin is set at the rear of the movable bracket 2 as a guide positioning pin for the battery pack installation. In the design of the battery pack bracket, the guiding and positioning function is added, which makes the installation of the battery pack easier, reduces the consumption of human resources, and improves work efficiency.

[0037] In some embodiments, there are multiple guide devices 23, and the multiple guide devices 23 are arranged at intervals along the length direction of the mounting plate 22. The above arrangement can ensure that the battery pack is effectively guided in the installation or removal of the battery pack on the length dimension of the movable bracket 2, ensure the installation accuracy of the battery pack and save manpower. It is understandable that the multiple guide devices 23 can be arranged at equal intervals or unequal intervals, and the specific arrangement can be set as needed according to actual use requirements.

[0038] In some embodiments, the battery pack bracket further includes a detachable connector, and a mounting hole 4 is provided on the mounting plate 22, wherein the detachable connector is connected to the bracket body 1 through the mounting hole 4, so that the movable bracket 2 can be detachably connected to the bracket body 1. The split battery pack bracket designed in the above-mentioned setting method can realize the split installation of the movable bracket 2 and the bracket body 1.

[0039] In some embodiments, the detachable connector includes a threaded connector. Furthermore, the threaded connector includes a bolt, and the mounting hole 4 includes a threaded hole. In the present disclosure, a threaded connector is connected to the bracket body 1 through a threaded hole, thereby realizing a detachable connection between the movable bracket 2 and the bracket body 1, so that the movable bracket 2 is detachable, which significantly increases the practicality of the battery pack bracket. On the other hand, the above arrangement avoids the problem of the movable bracket 2 being welded to the bracket body 1, resulting in thermal deformation of the structural beam of the bracket body 1. It can be understood that the detachable connector includes but is not limited to a threaded connector, and can also be a snap or the like.

[0040] In some embodiments, there are multiple detachable connectors, and a plurality of mounting holes 4 are provided on the mounting plate 22 , wherein the multiple detachable connectors and the multiple mounting holes 4 are connected to the bracket body 1 correspondingly.

[0041] refer to Figure 3 In some embodiments, the battery pack bracket further includes a limiting plate 5. The limiting plate 5 is disposed on the movable bracket 2, and the limiting plate 5 is used to limit the position of the battery pack.

[0042] In some embodiments, the battery pack bracket further includes a guide positioning member 6, which is disposed on the limiting plate 5, and is used to position the battery pack.

[0043] In some embodiments, the guide positioning member 6 comprises a stainless steel internally threaded round head cylindrical pin.

[0044] In some embodiments, the battery pack bracket further includes a liquid cooling pipe fixing bracket 7. The liquid cooling pipe fixing bracket 7 is arranged on the movable bracket 2, and the liquid cooling pipe fixing bracket 7 is used to fix the liquid cooling pipe of the battery pack. Through the above arrangement, the liquid cooling pipe of the battery pack can be effectively fixed by the movable bracket 2 to ensure the working reliability of the battery pack.

[0045] In some embodiments, the bottom bracket 3 is welded to the bracket body 1 by a welding process. The welding process can ensure the reliability of the connection between the bottom bracket 3 and the bracket body 1, thereby ensuring reliable support for the movable bracket 2.

[0046] refer to Figure 4 In some embodiments, a positioning hole 31 is provided on the base 3, wherein the base 3 is welded after a positioning tool is inserted into the positioning hole 31 for positioning.

[0047] Specifically, 2*20mm positioning holes 31 are designed on the bottom bracket 3 and the frame body 1 respectively. The positioning holes 31 are cut by laser, and the processing error is less than 0.1mm. When welding, the tool is inserted into the positioning hole 31 and then welded. The above design significantly improves the welding positioning accuracy of the bottom bracket 3, which can effectively prevent the tilting and warping problems of the battery pack after installation.

[0048] The split battery pack bracket disclosed in the present invention is a bilaterally symmetrical part, and uses movable brackets 2 placed on both sides of the battery rack to jointly carry the battery pack. The frame body 1 includes a welded bottom bracket 3 and a movable bracket 2. The bottom bracket 3 mainly plays the role of supporting and positioning the movable bracket 2. In the present disclosure, only the bottom bracket 3 and the frame body 1 need to be welded, thereby reducing the overall welding amount of the bracket and reducing the influence of welding thermal deformation on the bracket frame.
