Technical Field

[0001] The present application relates to the technical field of batteries, and particularly to a vibration tooling and a vibration test device. Background Art

[0002] With the increasing environmental pollution, how to reduce pollution emissions and improve our living environment has become an urgent problem to be solved. And the pollution emissions of traditional fuel vehicles using fossil fuels are also at the top of the list of problems to be solved. Therefore, both the government and automobile manufacturers highly favor the development of electric vehicles and have invested a large amount of human and material resources in developing electric vehicle technologies. The energy supply of electric vehicles comes from the power battery pack, so the battery pack technology is crucial for electric vehicles.

[0003] Existing battery packs are generally developed specifically for a single vehicle model, and the installation points of the battery pack correspond to the vehicle body. Therefore, the shapes of the battery packs assembled in various vehicles are different, which leads to differences in the external dimensions and installation points of the battery packs of different vehicle models. The tooling for vibrating the battery pack needs to be developed specifically for a specific battery pack and cannot be universal. Summary of the Utility Model

Specific embodiments

[0032] The following will clearly and completely describe the technical solutions of the present application in combination with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0033] The following in combination withFigures 1 - 7 , describe the vibration tooling provided in the embodiments of the present application.

[0034] Refer to Figure 1 As shown, in the embodiment provided by the present application, the vibration tooling includes a first support seat 100 and a second support seat 200. The first support seat 100 is used to connect with a vibration table, and a first connection surface 110 is formed on the first support seat 100; the second support seat 200 is used to fix the battery pack to be tested, and a second connection surface 210 is formed on the second support seat 200. The second support seat 200 is arranged on the first support seat 100 by contacting the first connection surface 110, and the total height of the first support seat 100 and the second support seat 200 is adjusted by changing the relative position of the second connection surface 210 on the first connection surface 110. In some specific embodiments, the first connection surface 110 and the second connection surface 210 are planes or curved surfaces with continuously changing heights. By changing the position of the second connection surface 210 on the first connection surface 110, the first support seat 100 can generate a displacement in the height direction, thereby changing the total height of the first support seat 100 and the second support seat 200.

[0035] Using the technical solution of the above embodiment of the present application, by setting the first support seat 100 and the second support seat 200, the first support seat 100 is used to connect with a vibration table, a first connection surface 110 is formed on the first support seat 100, and a second connection surface 210 is formed on the second support seat 200. The total height of the first support seat 100 and the second support seat 200 is adjusted by changing the relative position of the second connection surface 210 on the first connection surface 110. Since the battery pack to be tested can be fixed on the second support seat 200, it can be used to fix battery packs to be tested with different thicknesses, realizing the generalization of vibration tooling for different types of battery packs, saving tooling costs and development cycles for enterprises and laboratories.

[0036] Refer to Figure 1 , Figure 2As shown, in some embodiments provided by the present application, the tooling further includes a substrate 600 and a connecting plate 700. The substrate 600 is disposed on the vibration table and is used to connect with the vibration table. The first support seat 100 is disposed on the substrate 600; the connecting plate 700 is disposed on the second support seat 200, and the connecting plate 700 is connected to the second support seat 200. The connecting plate 700 is used to fix the battery pack to be tested. In some specific embodiments, the substrate 600 and the vibration table, the substrate 600 and the first support seat 100, the first support seat 100 and the second support seat 200, and the second support seat 200 and the connecting plate 700 are respectively fixedly connected by bolts, so that the vibration table, the substrate 600, the first support seat 100, the second support seat 200, and the connecting plate 700 form an integral structure, ensuring that the vibration force of the vibration table is transmitted to the battery pack to be tested without being affected; at the same time, it is also convenient for disassembly and for adjusting the relative positions of the first support seat 100 and the second support seat 200 to change the height of the entire tooling. In some specific embodiments, the substrate 600 and the connecting plate 700 are parallel to each other, and multiple groups of the first support seat 100 and the second support seat 200 are arranged at intervals along the length direction of the substrate 600 between the substrate 600 and the connecting plate 700, thereby enhancing the stability of the connecting plate 700 and enabling the vibration force of the vibration table to be transmitted to the battery pack to be tested without being affected.

[0037] In some embodiments provided by the present application, the first connection surface 110 and the second connection surface 210 are respectively inclined surfaces. The inclined surface has a first edge and a second edge that are oppositely arranged. Along the direction from the first edge to the second edge, the distance between the inclined surface and the vibration table gradually increases. Thus, by moving the second support seat 200 up or down along the inclined surface, the total height of the first support seat 100 and the second support seat 200 can be adjusted.

[0038] Referring to Figure 6 、 Figure 7 As shown, in some embodiments provided by the present application, step structures are respectively provided on the first connection surface 110 and the second connection surface 210. The step structure includes a horizontal surface 310 and a vertical surface 320 that are arranged at intervals. Specifically, the horizontal surface 310 of the first support seat 100 abuts against the horizontal surface 310 of the second support seat 200, and the vertical surface 320 of the first support seat 100 abuts against the vertical surface 320 of the second support seat 200. By adjusting the relative positions of the step structure of the second support seat 200 and the step structure of the first support seat 100, the height of the entire tooling can be adjusted; at the same time, the horizontal surface 310 and the vertical surface 320 can also play a limiting role on the first support seat 100 and the second support seat 200 in the horizontal and vertical directions, ensuring the overall stability of the first support seat 100 and the second support seat 200, which is beneficial to enabling the vibration force of the vibration table to be transmitted to the battery pack to be tested without being affected.

[0039] Reference Figure 4 and Figure 5 As shown, in some embodiments provided by the present application, a first through hole 120 is provided on the first support seat 100, and a second through hole 220 is provided on the second support seat 200. The axes of the first through hole 120 and the second through hole 220 are perpendicular to the horizontal plane 310; the tooling further includes a connecting bolt 400, and the connecting bolt 400 connects the first support seat 100 and the second support seat 200 by passing through the first through hole 120 and the second through hole 220. In some specific embodiments, two rows of first through holes 120 are provided on the first support seat 100, and two rows of second through holes 220 are provided on the second support seat 200. After adjusting the second support seat 200 so that some of the first through holes 120 and some of the second through holes 220 are coaxially aligned up and down, the corresponding connecting bolts 400 are respectively passed through the first through hole 120 and the second through hole 220 to connect the first support seat 100 and the second support seat 200. In some specific embodiments provided by the present application, the first through hole 120 and the second through hole 220 respectively include a smooth hole section 510 and a threaded hole section 520. The threaded hole section 520 is arranged close to the horizontal plane 310, and the diameter of the threaded hole section 520 is smaller than the diameter of the smooth hole section 510. By providing the smooth hole section 510, the installation speed of the connecting bolt 400 can be improved, and by making the diameter of the threaded hole section 520 smaller than the diameter of the smooth hole section 510, the bolt head of the connecting bolt 400 can be limited.

[0040] Reference Figure 1 and Figure 3 As shown, in some embodiments provided by the present application, a fixing hole 710 is provided on the connecting plate 700. The tooling further includes a fixing bolt 810 and a fixing nut 820. The fixing bolt 810 fixes the battery pack to be tested to the connecting plate 700 by passing through the fixing hole 710 and the bushing of the battery pack to be tested in sequence. In some specific embodiments of the present application, the fixing hole 710 is a strip-shaped hole opened along the length direction of the connecting plate 700. Thus, by adjusting the position of the fixing bolt 810 in the strip-shaped hole, the distance between the bushings of different models of battery packs to be tested can be adapted, and the same set of vibration tooling can be matched with different models of battery packs. In some specific embodiments of the present application, there are multiple strip-shaped holes, and the multiple strip-shaped holes are arranged along the width direction of the connecting plate 700. For example, there are three strip-shaped holes. By arranging the multiple strip-shaped holes along the width direction of the connecting plate 700, the positions of the bushings of different models of battery packs to be tested can be adapted, and the same set of vibration tooling can be matched with different models of battery packs.

[0041] The working process of the vibration tooling provided by the embodiments of the present application is as follows:

[0042] Place the second support base 200 on the first support base 100. After adjusting the first support base 100 and the second support base 200 to a suitable height, install the connecting bolts 400 into the corresponding first through holes 120 and second through holes 220, so that the first support base 100 and the second support base 200 are fixedly connected to each other;

[0043] Pass the bolt through the screw holes on the substrate 600 and the first support base 100 from bottom to top, so as to install the first support base 100 on the substrate 600;

[0044] Pass the bolt through the screw holes on the connecting plate 700 and the second support base 200 from top to bottom, so as to install the connecting plate 700 on the second support base 200;

[0045] Fix the substrate 600 to the corresponding screw holes of the vibration table with bolts, so as to install the entire tooling on the vibration table;

[0046] Place the bushings on both sides of the battery pack to be tested at the positions of the fixing holes 710 of the corresponding connecting plates 700 respectively. Adjust the fixing bolts 810 in the fixing holes 710 to the positions of the bushings. After the fixing bolts 810 pass through the bushings and the fixing holes 710, screw the fixing nuts 820 to fix the battery pack to be tested on the connecting plate 700;
