[0002] With the rapid development of electric machinery, the safety issues brought by electric machinery have become a hot spot and difficulty in the industry. As an important component of electric machinery, the battery module has very strict requirements on its working environment, and strict tests such as vibration testing are required before shipment. Vibration testing is an important verification process for inspecting module quality in product development, which can simulate the status of various safety indicators of the battery module during the driving of electric machinery. Most of the existing vibration test fixtures are universal designs with complex structures. Many of them are not designed for the structural characteristics and assembly characteristics of the battery module. Usually, the vibration test fixture is directly connected to the end plate of the battery module. There is no support at the bottom of the end plate, and there is a gap between the end plate and the bottom structure. The end plate is suspended, which is too different from the actual assembly structure of the battery module, resulting in a gap between the test results and the actual situation.

[0031] See also Figure 1 and Figure 2As shown, an embodiment of the present application provides a combined tooling for vibration testing of a battery module, comprising: a bottom plate 2 and two side structures. The bottom plate 2 is detachably connected to the vibration table 1, and the bottom plate 2 has a battery cell support surface. The bottom plate 2 has fewer holes on its surface and a flat surface, which is suitable for supporting the battery cells 61 of the battery module 6. The two side structures are located on both sides of the bottom plate 2, and both of the side structures are detachably connected to the vibration table 1. A limited space for accommodating each battery cell 61 of the battery module 6 is formed between the two side structures. The side structures are used to support the end plates 62 of the battery module 6. The lower edge of the end plates 62 of the battery module 6 is usually higher than the battery cells 61. The end plates 62 of the battery module 6 can be directly supported on the upper surface of the side structures, which is consistent with the actual assembly structure of the battery module 6. The side structure is provided with a fixing hole 41 for fixing the end plate 62. The side structure does not have a complex connection structure, but only has a fixing hole 41. By using the longitudinal hole on the end plate 62, one end of the fastener 5 can pass through the longitudinal hole of the end plate 62 from top to bottom to connect to the fixing hole 41, and the other end of the fastener 5 is limited to the end plate. The combined tooling for battery module vibration testing of the present application is designed according to the structural characteristics of the battery module 6. By providing the side structure on both sides of the bottom plate 2, the end plate 62 of the battery module 6 can be supported and fixed. The combined tooling for battery module vibration testing has a simple structure, fast product installation, and reduced costs.

[0032] In some possible implementations, a plurality of first connection holes 11 are provided on the vibration table 1, a plurality of second connection holes 21 are provided on the bottom plate 2, and the fasteners 5 are passed through the first connection holes 11 and the second connection holes 21 to connect and fix the vibration table 1 and the bottom plate 2. The fasteners 5 may be bolts, and the bottom plate 2 may be moved to a suitable position on the vibration table 1 as required, and then the bottom plate 2 may be fixed to the vibration table 1 by bolts.

[0033] In some possible implementations, the bottom plate 2 may be formed by splicing a plurality of plates, each of which is fixed to the bottom plate 2 by a fastener 5. Different battery modules 6 usually have different sizes. In the embodiment of the present application, the bottom plate 2 may be a modular structure, and a corresponding number of plates may be selected according to the actual size of the battery module 6. Each plate is located in the same plane, and the size of each plate in one direction is consistent with the size of each battery cell 61 of the battery module 6 along the arrangement direction, which can effectively support each battery cell 61 of the battery module 6, and at the same time facilitate the arrangement of side structures on both sides to support the end plates 62 of the battery module 6.

[0034] In some possible implementations, the side structure protrudes from the bottom plate 2 in a direction perpendicular to the bottom plate 2. The side plate structure is higher than the bottom plate 2, so that the end plate 62 of the battery module 6 can be supported conveniently.

[0035] In some possible embodiments, at least two fixing holes 41 are provided on the side structure, and one end of the fastener 5 can pass through the end plate 62 to be connected to the fixing hole 41. The end plate 62 of the battery module 6 is usually provided with two longitudinal holes for connecting and fixing with the battery box shell. In the present application, the longitudinal holes of the battery module 6 are reused. Two bolts are respectively passed through the longitudinal holes of the end plate 62 to be connected to the fixing holes 41 on the side structure. The fixing hole 41 can be a threaded hole for threaded connection with the bolt.

[0036] In some possible implementations, the side structure includes a support plate 3 and a mounting plate 4, the support plate 3 is attached to the vibration table 1, the mounting plate 4 is attached to the support plate 3, and the mounting plate 4 is provided with the fixing hole 41. The support plate 3 can be a universal plate, and the mounting plate 4 can be a replaceable plate, which is used to replace the mounting plate 4 according to the different sizes of the battery module 6, while the support plate 3 does not need to be replaced. The size of the support plate 3 is a set size, and the combined tooling for the battery module vibration test includes a variety of mounting plates 4, and the sizes of various mounting plates 4 are different, which can be replaced according to the different battery modules 6.

[0037] In some possible implementation schemes, the combined tooling for battery module vibration testing includes a plurality of the mounting plates 4, and the sizes and / or spacings of the fixing holes 41 of the various mounting plates 4 are different. The various mounting plates 4 are selectively attached to the support plate 3, so as to meet the needs of fixing different battery modules 6.

[0038] Preferably, the size of the mounting plate 4 includes any one or more of the thickness of the mounting plate 4, the length of the mounting plate 4, and the width of the mounting plate 4. For example, the spacing between the lower edge of the end plate 62 of different battery modules 6 and the lower edge of the battery cell 61 is different, and the mounting plate 4 of the corresponding thickness can be selected according to different battery modules 6 to effectively support the end plate 62 of the battery module 6.

[0039] In some possible implementation schemes, one end of the fastener 5 passes through the mounting plate 4 and the support plate 3 in sequence and is connected to the vibration table 1, and the other end of the fastener 5 is limited to the mounting plate 4. The first connection hole 11 on the vibration table 1 can be a threaded hole, and the fastener 5 can be a bolt to be threadedly connected to the first connection hole 11 on the vibration table 1.

[0040] It should be noted that a plurality of third connection holes 42 may be provided on the mounting plate 4, and the spacings of the third connection holes 42 on different mounting plates 4 are the same, and are equal to the spacings of the first connection holes 11 on the vibration table 1. Thus, each mounting plate 4 can be connected to the vibration table 1 through the fastener 5. Similarly, a plurality of fourth connection holes 31 are provided on the support plate 3, and the spacings of the fourth connection holes 31 may be equal to the spacings of the third connection holes 42.
