On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0028] like Figures 1 to 4 As shown, a battery pack placement bracket 100 provided by the utility model includes a column 10, a fixing member 20 located at the top of the column 10, and a side beam 30, a cross beam 40 and a support beam 50 located between the columns 10. Among them, the side beam 30 connects the adjacent columns 10 along the length direction of the battery pack placement bracket 100, and the cross beam 40 connects the adjacent columns 10 along the width direction of the battery pack placement bracket 100. The fixing member 20 is fixed to the top of the column 10, and is used to connect two adjacent battery pack placement brackets 100. The support beam 50 is located in the battery pack accommodating cavity 60 formed between the columns 10, and is used to support and position the battery pack 70. The bottom of the battery pack placement bracket 100 is provided with a retractable universal wheel 80, which is in an extended state when needed, so that the operator can move the battery pack placement bracket 100 when needed. The universal wheel 80 is in a retracted state when not in use, which can avoid unnecessary displacement of the battery pack placement bracket 100.

[0029] See especially Figure 2The column 10 of the battery pack placement bracket 100 is a square tube, which includes a first side plate 11, a second side plate 12, a third side plate 13 and a fourth side plate 14 connected end to end. Among them, the first side plate 11 is opposite to the first side plate 11 of another column 10 in the width direction of the battery pack placement bracket 100, the second side plate 12 is opposite to the second side plate 12 of another column 10 in the length direction of the battery pack placement bracket 100, the third side plate 13 is opposite to the first side plate 11, and is located on the outside of the column 10 in the width direction of the battery pack placement bracket 100, and the fourth side plate 14 is opposite to the second side plate 12, and is located on the outside of the column 10 in the length direction of the battery pack placement bracket 100. The first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14 are surrounded to form a cavity 15 located in the middle of the column 10. The fixing member 20 is inserted into the cavity 15 and tightly fits with the inner surface of the column 10. The upper part of the fixing member 20 forms a receiving groove 21 for receiving the upper column 10. The side wall of the receiving groove 21 fits with the column 10 of the upper battery pack placement bracket 100, which can realize the stable connection between the upper and lower battery pack placement brackets 100 and prevent shaking after connection. A support beam fixing hole (not shown) for connecting the support beam 50 is provided at the lower position on the first side plate 11 of the column 10, and a hoisting hole 16 for hoisting the battery pack placement bracket 100 is provided at the upper position on the third side plate 13. A battery pack fixing hole 17 for fixing the battery pack 70 is provided on the fourth side plate 14. The hoisting hole 16 is used to lift the battery pack placement bracket 100 by a hoisting device when the forklift is not high enough, and place it above the battery pack placement bracket 100 below to achieve stacking of the battery pack placement brackets 100. In addition, a column bottom plate 18 is welded to the bottom of the column 10 , and the column bottom plate 18 can increase the contact area between the bottom of the column 10 and the side beam 30 , making it easier for the upper column 10 to slide into the receiving groove 21 of the fixing member 20 .

[0030] like Figure 5 As shown, the fixing member 20 includes a rectangular fixing body 22, a fixing portion 23 located at the lower end of the fixing body 22, and a receiving groove 21 formed at the top of the fixing body 22. The fixing member 20 is installed on the column 10 through the fixing portion 23 at the lower end thereof, and is connected to the upper column 10 through the receiving groove 21 at the upper portion thereof.

[0031] Specifically, the fixed body 22 includes a bottom plate 221 and four first side walls 222 extending upward from the edge of the bottom plate 221. The accommodating groove 21 is formed between the bottom plate 221 and the four first side walls 222 of the fixing member 20, and is used to accommodate the column 10 of the upper battery pack placement bracket 100. The fixing portion 23 extends downward from the middle of the bottom plate 221 in a direction perpendicular to the bottom plate 221, and includes a second side wall 231 parallel to the four first side walls 222 of the fixing member 20. The outer surface of the second side wall 231 of the fixing portion 23 is indented inwardly relative to the outer surface of the first side wall 222 of the fixed body 22, and the dimension of the outer surface of the second side wall 231 of the fixing portion 23 indented inwardly relative to the outer surface of the first side wall 222 of the fixed body 22 is greater than the thickness of the column 10. In this way, when the fixing portion 23 is inserted into the column 10, the outer surface of the first side wall 222 of the fixing member 20 protrudes outward relative to the outer surface of the column 10, that is, the outer circumference of the fixing body 22 is greater than the outer circumference of the column 10. In this way, the cross-sectional size of the receiving groove 21 formed between the first side walls 222 can be equal to the outer circumferential size of the column 10, so that the receiving groove 21 can just accommodate the bottom of the column 10, which is convenient for the stable assembly of the upper and lower columns 10.

[0032] like Figure 6 As shown, the side beam 30 is also a square tube, which is welded and fixed between the two columns 10 in the front and rear directions, and is located at the top and near the bottom of the two columns 10 in the front and rear directions. The upper surface of the side beam 30 located at the top of the column 10 is flush with the upper surface of the fixing member 20, and the upper parts of the two ends of the side beam 30 located at the top of the column 10 are provided with notches 31 for avoiding the upper part of the fixing member 20. When the fixing member 20 is installed on the column 10, the side beam 30 is welded to the column 10 and the fixing member 20, and the part of the fixing member 20 protruding relative to the second side plate 12 of the column 10 is located in the notch 31. In this way, when the upper battery pack placement bracket 100 is placed on the lower battery pack placement bracket 100, the column 10 of the upper battery pack placement bracket 100 can slide on the upper surface of the lower battery pack placement bracket 100, which can reduce the requirements for placement accuracy and facilitate the assembly of the upper battery pack placement bracket 100 and the lower battery pack placement bracket 100.

[0033] like Figure 7 As shown, the crossbeam 40 is a telescopic crossbeam, which includes a sleeve 41 and a telescopic tube 42 inserted in the sleeve 41. The sleeve 41 is provided with a plurality of through holes 411 arranged along the length direction of the crossbeam 40, and the telescopic tube 42 is provided with a positioning pin 421 which can be retracted along the axial direction of the through hole 411. The positioning pin 421 is in a retracted position when the telescopic tube 42 slides relative to the sleeve 41. After the position of the telescopic tube 42 relative to the sleeve 41 is adjusted, it is inserted into the corresponding through hole 411. In this way, the length of the crossbeam 40 can be adjusted, so that the battery pack placement bracket 100 can adapt to battery packs 70 of different widths.

[0034] like Figure 8 As shown, the support beam 50 is fixed between the two columns 10 in the left and right directions by bolts inserted into the fixing holes of the support beam, and is located in the battery pack accommodating cavity 60 formed between the columns 10. The support beam 50 includes a support plate 51 and a vertical plate 52 extending from the support plate 51, the support plate 51 extends in the horizontal direction, the vertical plate 52 extends upward from the edge of the support plate 51 perpendicular to the support plate 51, and the support plate 51 and the vertical plate 52 surround a slide rail 53. An upwardly extending baffle 54 is provided at one end of the support plate 51, and the baffle 54 can abut against the battery pack 70 to prevent the battery pack 70 from sliding out of the battery pack accommodating cavity 60. A position of the vertical plate 52 near the baffle 54 is provided with a limit portion 55 extending upward, and the limit portion 55 includes a connection portion 551 connected to the vertical plate 52 and a limit piece 552 extending from one end of the connection portion 551 away from the support plate 51 to the battery pack accommodating cavity 60, and the limit piece 552 can be inserted into the card slot provided on the battery pack 70 to prevent the battery pack 70 from moving in the up and down direction. During installation, the battery pack 70 is placed on the slide rail 53 from the end of the support plate 51 where the baffle 54 is not provided, and at the same time, the limit piece 552 of the support plate 51 is inserted into the card slot formed on the battery pack 70, and then the battery pack 70 is pushed along the slide rail 53 to gradually slide into the battery pack accommodating cavity 60 until one end of the battery pack 70 abuts against the baffle 54, and then the battery pack 70 is fixed to the battery pack placement bracket 100 by screws passing through the fixing piece 71 provided on the battery pack 70 and the battery pack fixing hole 17 of the column 10.

[0035] It can be known from the above description that the battery pack placement bracket 100 of the utility model can realize the stacking of multiple battery pack placement brackets 100 by setting a fixing member 20 on the top of the column 10. The stacking process of the battery pack placement bracket 100 only requires placing one battery pack placement bracket 100 on another battery pack placement bracket 100, and then pushing the battery pack placement bracket 100 along the length direction so that the column 10 of the upper battery pack placement bracket 100 slides into the receiving groove 21 of the lower battery pack placement bracket 100. The stacking operation is simple, labor-saving, time-saving, and highly safe. In addition, when placing the battery pack 70 into the battery pack placement bracket 100, it is only necessary to push the battery pack 70 from one end of the battery pack placement bracket 100 into the battery pack placement bracket 100, and then use bolts to fix the battery pack 70, which is also simple and time-saving. In addition, the battery pack placement bracket 100 of the utility model can also realize the adjustment of the width, so that the battery pack placement bracket 100 can adapt to battery packs 70 of different widths, increasing its compatibility and scope of application. The universal wheels 80 at the bottom of the battery pack placement bracket 100 also ensure its mobility. The above advantages can meet the convenience of testing to the greatest extent, save preparation time before testing, and ensure convenient installation during testing and convenient disassembly and transportation after testing.

[0036] It should be noted that the battery pack placement bracket 100 of the present invention is not only suitable for placing the battery pack 70 when the battery pack 70 is tested, but is also suitable for other occasions where the battery pack 70 needs to be placed or stacked.
