Technical Field

[0001] The present invention relates to the technical field of battery testing, and particularly to a vibration testing tooling for battery cells. Background Art

[0002] Thin battery cells usually adopt aluminum-plastic soft packaging, which has the advantages of small volume, low hardness and high capacity, and is widely used in electronic products or wearable devices. In order to evaluate the performance and safety of thin battery cells under different vibration environments and ensure their reliability and durability in actual use, it is necessary to use vibration testing equipment to perform vibration tests on thin battery cells.

[0003] At present, most vibration testing equipment has only a single vibration direction. When performing vibration tests on thin battery cells, it is necessary to build test benches in multiple directions to meet the multi-directional testing of thin battery cells. However, building the benches multiple times is not only troublesome in operation, but also reduces the testing efficiency. Moreover, since thin battery cells use soft packaging, it is difficult to fix and clamp them, and frequent clamping is likely to cause damage to thin battery cells. Summary of the Invention

[0015] Further preferably, the second limiting member is connected or not connected to the first limiting member.

[0016] Further preferably, there are two first limiting members, and the two first limiting members are arranged on both sides of the cell in the second direction.

[0017] Further preferably, the first limiting member includes:

[0018] A straight line segment, the straight line segment extends along the first direction and is used to limit the moving pair of the cell in the second direction.

The first support plate intersects and is fixed to the third support plate. When the first support plate is installed on the vibration test workbench, it can meet the vibration test of the battery cell in the first direction. By flipping the battery cell vibration test tooling, the third support plate is installed on the vibration test workbench, thereby meeting the vibration test of the battery cell in the second direction.

[0048] As Figures 1 - 7 shown, this embodiment provides a battery cell vibration test tooling, which has a first direction X, a second direction Y and a third direction Z that intersect pairwise.

[0049] In some embodiments, the first direction X, the second direction Y and the third direction Z intersect pairwise at right angles.

[0050] In some embodiments, the battery cell vibration test tooling includes a support table 10, a support 20 and a cover plate 30. Among them, the cover plate 30 is used to fix the battery cell 50 on the support 20, and the support 20 is then connected to the support table 10 to meet the vibration test requirements of the battery cell 50 in multiple directions.

[0051] In a specific embodiment, the support platform 10 includes a first support plate 11, a second support plate 12, and a third support plate 13. The first support plate 11 intersects and is fixed to the third support plate 13. The second support plate 12 intersects and is fixed to the first support plate 11 and the third support plate 13 respectively. The support 20 is connected to the second support plate 12. The cover plate 30 is spaced from the support 20 along the third direction Z. The cover plate 30 is connected to the support 20 to clamp the battery cell 50. Thus, when the first support plate 11 is installed on the vibration test workbench, the vibration test of the battery cell 50 in the first direction X can be satisfied. Flip the battery cell vibration test tooling so that the third support plate 13 is installed on the vibration test workbench, thereby satisfying the vibration test of the battery cell 50 in the second direction Y. When it is necessary to perform a vibration test on the battery cell 50 in the third direction Z, only need to remove the support 20 from the second support plate 12, and directly install the support 20 on the vibration test workbench to realize the vibration test of the battery cell 50 in the third direction Z. After the test is completed, the battery cell 50 is taken out by disassembling the cover plate 30. In this embodiment, when the vibration test equipment has only a single vibration direction, it can be realized that a thin battery cell can be set up once to meet the vibration test requirements in multiple directions, avoiding damage to the thin battery cell caused by frequent clamping of the thin battery cell, and having the advantages of simple operation and high test efficiency.

[0052] In some embodiments, the second support plate 12 has a mounting surface 122 extending along the first direction X and the second direction Y. The mounting surface 122 is disposed on both sides of the second support plate 12 in the third direction Z. The support 20 is detachably mounted on the mounting surface 122. By forming the mounting surface 122 on both sides of the second support plate 12, a multi-station design is formed, so that multiple battery cells 50 can be simultaneously arranged on the mounting surface 122 for simultaneous and synchronous detection, improving the test efficiency.

[0053] In some embodiments, the first support plate 11, the second support plate 12, and the third support plate 13 are perpendicular to each other in pairs to ensure that the vibration test of the battery cell can be carried out along the specified direction during the vibration test process, without the need to calibrate the direction before the test.

[0054] In some embodiments, the support platform 10 is an integral structure, that is, the first support plate 11, the second support plate 12, and the third support plate 13 are integrally formed.

[0055] In other embodiments, the support platform 10 is a split structure, that is, the first support plate 11, the second support plate 12, and the third support plate 13 are detachably connected to each other in pairs, such as by bolt connection, mortise and tenon connection, or snap connection, etc. It should be noted that bolt connection, mortise and tenon connection, or snap connection are all existing technologies and will not be described in detail here.

[0056] In some embodiments, each mounting surface 122 can mount at least one support 20 to meet the mounting test of at least one battery cell 50. The term "at least one" means that the quantity is greater than or equal to 1, such as 1, 2, 3, ……, 8, 9, or even more. Those skilled in the art can arrange according to actual needs and no specific limitation is made here. For those of ordinary skill in the technical field, without departing from the technical principle of the present invention, several improvements and substitutions can also be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.

[0057] In some embodiments, when there are more than two supports 20 on each mounting surface 122, a matrix arrangement is adopted.

[0058] In some embodiments, to further improve the test efficiency, there are at least two second support plates 12. The at least two second support plates 12 are spaced along the third direction Z to provide more mounting surfaces 122, meet the mounting requirements of more battery cells 50, and realize the simultaneous and synchronous detection of multiple battery cells 50, thereby improving the test efficiency.

[0059] In some embodiments, the vibration workbench is usually provided with through holes to meet the fixed connection of the support table 10. For this purpose, the first support plate 11 is provided with first mounting holes 111 penetrating along the first direction X, the third support plate 13 is provided with second mounting holes 131 penetrating along the second direction Y, and the support 20 is provided with third mounting holes 22 penetrating along the third direction Z, so as to meet the assembly of the first support plate 11 or the third support plate 13 or the support 20 with the vibration workbench.

[0060] In the above embodiments, the apertures of the first mounting holes 111, the second mounting holes 131, and the third mounting holes 22 are the same and match the through holes of the vibration workbench, thereby reducing the processing requirements of the vibration workbench, eliminating the need to set through holes of multiple specifications, and realizing the multi-purpose use of one hole.

[0061] In some embodiments, the support 20 is further provided with a first fastener 21, and the support 20 is connected to the second support plate 12 through the first fastener 21.

[0062] In some embodiments, the cover plate 30 is further provided with a second fastener 31, and the cover plate 30 is connected to the support 20 through the second fastener 31.

[0063] In other embodiments, both the first fastener 21 and the second fastener 31 are preferably bolt assemblies.

[0064] In some embodiments, the cover plate 30 is connected to the support 20 to clamp the battery cell 50. To prevent the battery cell 50 from shifting during the vibration test, the battery cell vibration test tooling further includes a limiting structure 40. The limiting structure 40 is disposed between the cover plate 30 and the support 20. A limiting groove is formed in the middle of the limiting structure 40. The battery cell 50 is disposed in the limiting groove. The limiting structure 40 is used to limit the battery cell 50 to prevent the battery cell 50 from shifting during the vibration test and affecting the test result.

[0065] In some embodiments, the limiting structure 40 includes a first limiting member 41 and a second limiting member 42. Both the first limiting member 41 and the second limiting member 42 are connected to the support 20. The first limiting member 41 and the second limiting member 42 jointly enclose to form a limiting groove. The battery cell 50 is placed in the limiting groove. After the cover plate 30 is covered, the battery cell 50 can be limited while being clamped, thereby preventing the battery cell 50 from shifting during the vibration test and affecting the test result.

[0066] In some embodiments, the limiting structure 40 further includes a third fastener 411 and a fourth fastener 421. The third fastener 411 is used to fix the first limiting member 41 to the support 20, and the fourth fastener 421 is used to fix the second limiting member 42 to the support 20.

[0067] In some embodiments, the second limiting member 42 is connected to the first limiting member 41 to form an integral structure, which can improve the installation efficiency of the limiting structure 40.

[0068] In other embodiments, the second limiting member 42 is not connected to the first limiting member 41, that is, the second limiting member 42 and the first limiting member 41 are of a split structure, so as to be able to adjust the size of the limiting groove according to the size of the battery cell 50 and improve the adaptability.

[0069] In some embodiments, there are two first limiting members 41. The two first limiting members 41 are disposed on both sides of the battery cell 50 in the second direction Y. Specifically, the first limiting member 41 includes a straight line segment 41a. The straight line segment 41a extends along the first direction X and is used to limit the moving pair of the battery cell 50 in the second direction Y to prevent the battery cell 50 from shifting in the second direction Y during the vibration test and ensure the accuracy of the test result.

[0070] In some embodiments, the second limiting member 42 extends along the second direction Y and is used as a moving pair for the battery cell 50 in the second direction Y; the first limiting member 41 further includes a bent section 41b, one end of the bent section 41b is connected to the straight section 41a, and the other end extends along the second direction Y; wherein, the bent section 41b and the second limiting member 42 are respectively located on both sides of the battery cell 50 in the first direction X, and the bent section 41b and the second limiting member 42 are used to limit the moving pair of the battery cell 50 in the first direction X, so as to avoid the battery cell 50 from shifting in the first direction X during the vibration test and ensure the accuracy of the test results.

[0071] In some embodiments, along the second direction Y, a gap 43 is reserved between the two bent sections 41b to allow the pole columns of the battery cell 50 to protrude, so as to satisfy the electrical connection between the battery cell 50 and the external charging and discharging equipment, and can simulate the vibration test of the battery cell 50 under normal use conditions.

[0072] The working process of the present invention is as follows: Refer to Figures 1 - 7 , before the vibration test of the battery cell 50 is required, select the first limiting member 41 and the second limiting member 42 with appropriate specifications, and fix them on the support 20 through the third fastener 411 and the fourth fastener 421 respectively. Place the battery cell 50 into the limiting groove formed by the common enclosure of the first limiting member 41 and the second limiting member 42, cover the cover plate 30, and connect and lock the cover plate 30 and the support 20 through the second fastener 31. Finally, use the first fastener 21 to fix the support 20 on the installation surface 122 of the second support plate 12 to complete the construction of the battery cell 50;

[0073] When performing the vibration test, install the first support plate 11 on the vibration test workbench, start the vibration test equipment, and realize the vibration test of the battery cell 50 in the first direction X;

[0074] When the vibration test equipment stops, flip the battery cell vibration test tooling so that the third support plate 13 is installed on the vibration test workbench, start the vibration test equipment, and realize the vibration test of the battery cell 50 in the second direction Y;

[0075] When the vibration test equipment stops, remove the support 20 from the second support plate 12, directly install the support 20 on the vibration test workbench, start the vibration test equipment, and realize the vibration test of the battery cell 50 in the third direction Z;

[0076] After the test is completed, remove the cover plate 30 and take out the battery cell 50 to complete the test steps.

[0077] In summary, the embodiment of the present invention provides a cell vibration test tooling. By forming mounting surfaces 122 on both sides of the second support plate 12, a multi-station design is formed, enabling multiple cells 50 to be arranged on the mounting surfaces 122 simultaneously for simultaneous and synchronous detection, thereby improving the test efficiency. The first support plate 11 intersects and is fixed to the third support plate 13. When the first support plate 11 is installed on the vibration test workbench, it can meet the vibration test of the cell 50 in the first direction X. By flipping the cell vibration test tooling so that the third support plate 13 is installed on the vibration test workbench, the vibration test of the cell 50 in the second direction Y can be satisfied. When it is necessary to perform a vibration test on the cell 50 in the third direction Z, only the support 20 needs to be removed from the second support plate 12 and directly installed on the vibration test workbench to achieve the vibration test of the cell 50 in the third direction Z. After the test, the cell 50 can be taken out by removing the cover plate 30. It can be seen that when the vibration test equipment has only a single vibration direction, the present invention can realize that a thin cell can meet the vibration test requirements in multiple directions with a single setup, avoiding damage to the thin cell caused by frequent clamping. The present invention has the advantages of simple operation and high test efficiency.

[0078] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention. The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above preferred embodiments. The embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention.

[0079] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in the embodiments can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
