The support frame 2 is provided with a hollow area 221, and when the battery package 1 to be detected is placed on the support frame 2, the hollow area 221 exposes part of the bottom of the battery package 1 to be detected, so that the external testing device can pass through the hollow area 221 to perform bottom ball impact, bottom extrusion and bottom needle test on the battery package 1 to be detected.

[0033] In the patent, the fixed mechanism 3 is movably connected to the support frame 2, so that when the battery package 1 to be detected of different sizes is placed on the support frame 2, the interval of the fixed mechanism 3 itself can be adjusted by moving the fixed mechanism 3 on the support frame 2, so that the fixed mechanism 3 can fix the battery package 1 to be detected of different sizes on the support frame 2, and thus the test tool can be suitable for bottom ball impact, bottom extrusion and bottom needle test of different battery packages, reducing production cost and improving production efficiency.

[0034] In the embodiment, the support frame 2 includes at least two legs 21 extending in the vertical direction, and a support platform 22 arranged at the top of the at least two legs 21. The battery package 1 to be detected is placed on the support platform 22, and the hollow area 221 is arranged on the support platform 22. In the patent, the support frame 2 includes at least two legs 21 and a support platform 22, the at least two legs 21 extend in the vertical direction, and the support platform 22 is arranged at the top of the at least two legs 21.

[0035] When testing, the battery pack 1 to be tested is placed on the support platform 22, so that the support platform 22 lifts the battery pack 1 to be tested off the ground. Because the hollowed-out area 221 is provided on the support platform 22, the external testing device can perform bottom ball impact, bottom extrusion, and bottom needle puncture tests on the battery pack 1 to be tested through the hollowed-out area 221.

[0036] In this embodiment, the support platform 22 includes a peripheral frame 222, a plurality of Y-direction support plates 223 extending along the Y-axis direction, and a plurality of X-direction support plates 224 extending along the X-axis direction. The plurality of Y-direction support plates 223 are arranged at intervals within the peripheral frame 222, and the plurality of X-direction support plates 224 are arranged at intervals within the peripheral frame 222.

[0037] In this patent, the support platform 22 includes a peripheral frame 222, a plurality of Y-direction support plates 223, and a plurality of X-direction support plates 224.

The plurality of X-direction support plates 224 are arranged at intervals within the peripheral frame 222 and extend along the X-axis direction. Thus, a plurality of rectangular holes arranged in an array are formed between the plurality of Y-direction support plates 223 and the plurality of X-direction support plates 224, and the plurality of rectangular holes arranged in an array are the hollowed-out area 221.

[0038] It can be predicted that in actual detection, the bottom of the battery pack 1 to be tested is provided with a plurality of detection points. Therefore, in this patent, the plurality of rectangular holes arranged in an array formed on the support platform 22 can not only support the battery pack 1 to be tested, but also expose the plurality of detection points on the bottom of the battery pack 1 to be tested. Thus, the external testing device can perform bottom ball impact, bottom extrusion, and bottom needle puncture tests on the plurality of detection points of the battery pack 1 to be tested through the plurality of rectangular holes.

[0039] When different sizes of battery packs 1 to be tested are placed on the support platform 22, the positions of the battery packs 1 to be tested on the support platform 22 are adjusted. Thus, the detection points on the bottom of the battery packs 1 to be tested of different sizes can be exposed through the rectangular holes. Therefore, this testing tool can be suitable for bottom ball impact, bottom extrusion, and bottom needle puncture tests of different battery packs, which reduces production costs and improves production efficiency.

[0040] Further, in this embodiment, a sliding groove 2221 is provided in the peripheral frame 222. The plurality of Y-direction support plates 223 are slidingly connected to the sliding groove 2221, and the plurality of X-direction support plates 224 are arranged at the bottom of the sliding groove 2221. Thus, the plurality of X-direction support plates 224 support the plurality of Y-direction support plates 223.

[0041] When the battery pack 1 to be detected is placed on the support platform 22, the plurality of Y-direction support plates 223 support the battery pack 1 to be detected, so that the support platform 22 can support the battery pack 1 to be detected and expose a plurality of detection points at the bottom of the battery pack 1 to be detected through the hollow area 221 formed between the plurality of Y-direction support plates 223 and the plurality of X-direction support plates 224.

[0042] The plurality of Y-direction support plates 223 are slidably connected to the sliding groove 2221 in the peripheral frame 222, so that the distance between the adjacent two Y-direction support plates 223 can be adjusted by moving the Y-direction support plates 223 in the sliding groove 2221, and the size of the hollow area 221 formed between the plurality of Y-direction support plates 223 and the plurality of X-direction support plates 224 can be adjusted according to the size of the battery pack 1 to be detected, so that the test tool can be applied to the bottom ball impact test, bottom extrusion test and bottom puncture test of different battery packs, and the production cost is reduced and the production efficiency is improved.

[0043] Specifically, in actual implementation, the X-direction strip-shaped hole 2222 communicating the sliding groove 2221 with the outside can be arranged on the peripheral frame 222, and the threaded hole can be arranged on the Y-direction support plate 223, and one end of the bolt is threaded through the X-direction strip-shaped hole 2222 and screwed with the threaded hole on the Y-direction support plate 223, so that the Y-direction support plate 223 can be fixed on the peripheral frame 222 by tightening the bolt, and the Y-direction support plate 223 can be moved in the sliding groove 2221 by loosening the bolt.

[0044] In the embodiment, the fixing mechanism 3 includes two fixing members and two connecting members, the two fixing members are movably connected to the support platform 22 and detachably connected to the support platform 22 through the two connecting members. During testing, the two fixing members are moved on the support platform 22 according to the size of the battery pack 1 to be detected, and the distance between the two fixing members is adjusted to adapt to the size of the battery pack 1 to be detected.

[0045] Then, the two fixing members are fixed on the support platform 22 through the two connecting members, and then the battery pack 1 to be detected is placed on the support platform 22, so that the two fixing members can fix the two ends of the battery pack 1 to be detected, and the test tool can be applied to the bottom ball impact test, bottom extrusion test and bottom puncture test of different battery packs, and the production cost is reduced and the production efficiency is improved.

[0046] In the embodiment, the fixing member comprises a Y-direction fixing plate 33 slidably connected with the support frame 2, a screw rod 31 arranged on the Y-direction fixing plate 33 in a vertical direction, and a pressing nut 32 used to press one end of the battery pack 1 to be detected, the pressing nut 32 being screwed with the screw rod 31 above the Y-direction fixing plate 33. In the patent, the fixing member comprises the Y-direction fixing plate 33, the screw rod 31, and the pressing nut 32, the Y-direction fixing plate 33 being slidably connected with the support frame 2 and extending along the Y-axis direction, the screw rod 31 being arranged on the Y-direction fixing plate 33 in a vertical direction, and the pressing nut 32 being screwed with the screw rod 31 extending above the Y-direction fixing plate 33.

[0047] Therefore, when the test is performed, the Y-direction fixing plate 33 can be moved on the support frame 2 according to the size of the battery pack 1 to be detected, so as to adjust the positions of the two screw rods 31 on the support frame 2, and then adjust the positions of the two pressing nuts 32 on the support frame 2. When the battery pack 1 to be detected with different sizes is placed on the support frame 2, the two ends of the battery pack 1 to be detected are pressed by the two pressing nuts 32 respectively, so as to fix the battery pack 1 to be detected with different sizes on the support frame 2, and make the test tool suitable for the bottom ball impact test, the bottom extrusion test, and the bottom puncture test of the battery pack with different sizes, reduce the production cost, and improve the production efficiency.

[0048] Specifically, in the actual implementation, the Y-direction fixing plate 33 can also be slidably connected with the sliding groove 2221 on the peripheral frame 222, a threaded hole is arranged on the Y-direction fixing plate 33, and the Y-direction fixing plate 33 is fixed on the peripheral frame 222 by screwing the other end of the bolt through the X-direction strip-shaped hole 2222 on the peripheral frame 222 and being screwed with the threaded hole on the Y-direction fixing plate 33, so as to be fixed on the peripheral frame 222 by screwing the bolt, and be moved in the sliding groove 2221 by unscrewing the bolt.

[0049] Therefore, when the battery pack 1 to be detected with different sizes is placed on the support platform 22, the Y-direction support plate 223 and the Y-direction fixing plate 33 can simultaneously support the battery pack 1 to be detected, so as to enhance the stability of the test tool in fixing the battery pack 1 to be detected, and then improve the test effect of the battery pack 1 to be detected.

[0050] Further, in the embodiment, the Y-direction fixing plate 33 is provided with a Y-direction strip-shaped hole 331, the screw rod 31 penetrates the Y-direction strip-shaped hole 331, and the connecting member comprises a mounting nut 34 screwed with one end of the screw rod 31 penetrating the Y-direction strip-shaped hole 331 below the Y-direction fixing plate 33.

[0051] Therefore, in the patent, a Y-direction strip-shaped hole 331 is arranged on the Y-direction fixed plate 33 in the axial direction. When the screw rod 31 is arranged on the Y-direction fixed plate 33 in the vertical direction, it penetrates the Y-direction strip-shaped hole 331. The connecting piece includes a mounting nut 34, which is arranged below the Y-direction fixed plate 33 and is screwed with one end of the screw rod 31 penetrating the Y-direction strip-shaped hole 331. When the mounting nut 34 is tightened, the screw rod 31 is fixed on the Y-direction fixed plate 33; when the mounting nut 34 is loosened, the screw rod 31 can move along the Y-direction strip-shaped hole 331 on the Y-direction fixed plate 33, so as to adjust the position of the screw rod 31 on the support frame 2 in the Y-axis direction, and further adjust the position of the pressing nut 32 on the support frame 2 in the Y-axis direction, so as to make the test tool suitable for the bottom ball impact test, bottom extrusion test and bottom puncture test of different models of battery packs.

[0052] In the foregoing embodiment, it is mentioned that the support platform 22 includes a plurality of X-direction support plates 224 extending in the X-axis direction, and the plurality of X-direction support plates 224 are arranged at intervals on the bottom of the sliding groove 2221. Therefore, the bottom of the screw rod 31 penetrates the Y-direction strip-shaped hole 331 and passes between the adjacent two X-direction support plates 224. Therefore, when the screw rod 31 moves along the Y-direction strip-shaped hole 331 on the Y-direction fixed plate 33, it is limited by the two X-direction support plates 224 through which it passes. That is, the adjustment range of the screw rod 31 in the Y-axis direction is equal to the distance between the adjacent two X-direction support plates 224.

[0053] Further, in the embodiment, the battery pack 1 to be detected is provided with a connecting plate 11 at both ends, and the connecting plate 11 is provided with a through hole 111. After adjusting the positions of the two screw rods 31 on the support platform 22 and fixing the two screw rods 31 on the Y-direction fixed plate 33 by the two mounting nuts 34 respectively, the battery pack 1 to be detected is placed on the support platform 22, and the connecting plates 11 at both ends of the battery pack 1 to be detected are respectively sleeved on the two screw rods 31 through the through holes 111.

[0054] Then, the two pressing nuts 32 are respectively screwed with the two screw rods 31 above the support platform 22, so that the two pressing nuts 32 respectively abut against the connecting plates 11 at both ends of the battery pack 1 to be detected, thereby fixing the battery pack 1 to be detected of different sizes on the support platform 22, and making the fixation of the battery pack 1 to be detected on the support platform 22 more stable, and further making the test effect of the battery pack 1 to be detected better.

[0055] In the embodiment, the pressing nut 32 includes a screwing part 321 screwed with the screw rod 31, and a pressing part 322 pressing the connecting plate 11, and the pressing part 322 extends vertically below the screwing part 321.

[0056] The pressing part 322 extends vertically below the screwing part 321, and the cross-sectional area of the pressing part 322 is larger than that of the screwing part 321, so that when the screwing part 321 and the pressing part 322 are screwed to the screw rod 31 and the pressing part 322 abuts against the connecting plate 11, the connecting plate 11 is pressed by the pressing part 322, so that the fixing of the battery pack 1 to be detected on the support platform 22 is more stable, and the testing effect of the battery pack 1 to be detected is better.

[0057] In the embodiment, the test tool further comprises a base 23 arranged at the bottom of the support leg 21, the base 23 abuts against the ground to support the support leg 21, and the cross-sectional area of the base 23 is larger than that of the support platform 22. In the patent, the test tool further comprises the base 23, and the support leg 21 is arranged on the base 23 to support the support leg 21 by the base 23, and thus support the battery pack 1 to be detected fixed on the support platform 22.

[0058] Since the cross-sectional area of the base 23 is larger than that of the support platform 22, the support leg 21 is supported by the base 23 abutting against the ground, which can further enhance the stability of the test tool structure, and thus the testing effect of the battery pack 1 to be detected is better.
