For example, if the third mounting plate surface 230 is provided with four sixth mounting holes 232, the third fastening assembly may include four third fasteners.

For example, the first clamp 240 and the second clamp 250 may be a square plate structure, the first clamp 240 has a first plate surface and a second plate surface, the second clamp 250 has a first plate surface and a second plate surface, the second plate surface of the first clamp 240 is provided with a first groove 242, and the second plate surface of the second clamp 250 is provided with a second groove 252. When the first clamp 240 and the second clamp 250 are locked, the first groove 242 and the second groove 252 are enclosed to form a receiving cavity for accommodating the battery 70 to be tested.

[0066] The first plate surface of the first clamp 240 or the first plate surface of the second clamp 250 can be the first mounting plate surface 210 of the clamp assembly 20. Exemplarily, the first clamp 240 also has a first side surface and a second side surface, and the second clamp 250 also has a first side surface and a second side surface, the first side surface of the first clamp 240 is arranged correspondingly to the first side surface of the second clamp 250, and the second side surface of the first clamp 240 is arranged correspondingly to the second side surface of the second clamp 250, then the first side surface of the first clamp 240 and the first side surface of the second clamp 250 constitute the second mounting plate surface 220 of the clamp assembly 20, and the second side surface of the first clamp 240 and the second side surface of the second clamp 250 constitute the third mounting plate surface 230 of the clamp assembly 20.

[0067] In one embodiment, Figure 3 As shown, the battery testing tool also includes a fourth fastening component 60; the first clamping member 240 is provided with a plurality of seventh mounting holes 244, and the second clamping member 250 is provided with a plurality of eighth mounting holes 254, and each seventh mounting hole 244 is arranged in a one-to-one correspondence with each eighth mounting hole 254; the fourth fastening component 60 is used to penetrate the correspondingly arranged seventh mounting holes 244 and eighth mounting holes 254 to fix the battery 70 to be tested.

[0068] The fourth fastening assembly 60 may be composed of a plurality of fourth fasteners, which may be bolts, and the number of the fourth fasteners is the same as the number of the seventh mounting holes 244. For example, if the first clamping member 240 has four seventh mounting holes 244, the fourth fastening assembly 60 may include four fourth fasteners. The number of the seventh mounting holes 244 is the same as the number of the eighth mounting holes 254. For example, if the first clamping member 240 includes four seventh mounting holes 244, the second clamping member 250 includes four eighth mounting holes 254, and the four seventh mounting holes 244 are arranged in a one-to-one correspondence with the four eighth mounting holes 254.

[0069] When performing a mechanical test on the battery 70 to be tested, the first end of the battery 70 to be tested is set in the first groove 242 of the first clamp 240, and the second end of the battery 70 to be tested is set in the second groove 252 of the second clamp 250. The fourth fastening component 60 passes through the corresponding seventh mounting hole 244 and the eighth mounting hole 254, and then the first clamp 240 and the second clamp 250 are locked, so that the battery 70 to be tested is locked and fixed between the first clamp 240 and the second clamp 250. Furthermore, after the clamping assembly 20 clamps and fixes the battery 70 to be tested, one mounting plate surface of the clamping assembly 20 can be installed and set in the corresponding mounting area of ​​the support plate 10, so that the battery 70 to be tested can be subjected to a mechanical test in one direction; after completing the test in one direction, the clamping assembly 20 is disassembled and flipped to another direction on the same test equipment, and the other mounting plate surface is re-fixed on the corresponding mounting area of ​​the support plate 10, so that the battery 70 to be tested can be subjected to a mechanical test in another direction, thereby reducing the cost of the test equipment. When changing to a different direction for mechanical testing, there is no need to disassemble the battery 70 to be tested, which simplifies the test process and shortens the test time.

[0070] In one embodiment, Figure 3 and Figure 4 As shown, the first groove 242 includes a plurality of first sub-grooves 2422, and the second groove 252 includes a plurality of second sub-grooves 2522; each first sub-groove 2422 is arranged in one-to-one correspondence with each second sub-groove 2522, and a accommodating sub-cavity is formed between the first sub-groove 2422 and the corresponding second sub-groove 2522; each accommodating sub-cavity is used to accommodate multiple battery cells 710 to be tested.

For example, the second plate surface of the first clamping member 240 may be provided with a plurality of first sub-grooves 2422 at intervals, and the second plate surface of the second clamping member 250 may be provided with a plurality of second sub-grooves 2522 at intervals. When the first clamping member 240 and the second clamping member 250 are locked, the first sub-grooves 2422 and the corresponding second sub-grooves 2522 are enclosed to form a receiving sub-cavity for receiving the battery cell 710 to be tested.

[0072] When the battery 70 to be tested is subjected to a mechanical test, the first end of each battery cell 710 to be tested is respectively arranged in the corresponding first sub-groove 2422 of the first clamp 240, and the second end of each battery cell 710 to be tested is arranged in the corresponding second sub-groove 2522 of the second clamp 250. The fourth fastening assembly 60 passes through the corresponding seventh mounting hole 244 and the eighth mounting hole 254 to lock the first clamp 240 and the second clamp 250, so that the battery 70 to be tested is locked and fixed between the first clamp 240 and the second clamp 250, thereby improving the convenience of installing and fixing each battery cell 710 to be tested.

[0073] In one embodiment, Figure 3 As shown, the support plate 10 has a first plate surface and a second plate surface corresponding to the first plate surface. The first plate surface is provided with a mounting area, and the second plate surface is provided with a fixing area 140 . The support plate 10 is used to be set on the test equipment through the fixing area 140 .

[0074] Among them, the support plate 10 has a first plate surface and a second plate surface, and the first plate surface corresponds to the second plate surface. The first plate surface of the support plate 10 is provided with an installation area, and the installation area can be used to support and fix the clamping assembly 20, and the second plate surface of the support plate 10 can be used to be set on the test equipment. It should be noted that the test equipment can be used to perform vibration and mechanical shock tests on the battery 70 to be tested. The fixing area 140 of the second plate surface of the support plate 10 can be set on the test equipment by screw connection or the like. During the mechanical test of the battery 70 to be tested in different directions, there is no need to disassemble the support plate 10, and there is no need to replace the test equipment. It is only necessary to disassemble and replace the clamping assembly 20 in different directions, so as to realize mechanical tests of the battery 70 to be tested in different directions, thereby simplifying the test process, reducing the cost of the test equipment, and improving the efficiency of mechanical testing of the battery 70 to be tested.
