[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the following embodiments are intended only to illustrate the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some of the embodiments of the present invention and not all of them. All other embodiments obtained by persons of ordinary skill in the art without creative effort are also within the scope of protection of the present invention.

[0030] See also Figure 1 and Figure 5 , Figure 1 is an assembly diagram of the test device provided in an embodiment of the present application, Figure 5 It is a structural diagram of the test device base 100 provided in an embodiment of the present application. The vibration testing device of the present invention includes a base 100, a support frame 200 and a fixing assembly 300, wherein the base 100 includes a workbench 110 and a support table 120, the support table 120 is arranged at both ends of the workbench 110 and is connected to the workbench 110, and the workbench 110 and the support table 120 are surrounded to form an avoidance groove 131, which simulates the vibration environment of the battery pack in actual use, while optimizing the transmission path of the vibration energy, reducing the attenuation and interference of the vibration inside the device, and improving the accuracy and effectiveness of the test. In addition, the support frame 200 is arranged on the support table 120, and the support frame 200 is used to connect with the battery pack. The fixing assembly 300 is installed on the support frame 200, which can realize the clamping and limiting effect on the battery pack, ensuring that the battery pack can be firmly fixed on the support frame 200 and can remain stable even in a strong vibration environment.

[0031] Preferably, the vibration testing device of the present invention is made of high-strength materials and has a reasonable structural design, which can effectively prevent equipment damage accidents caused by vibration and ensure the safety and reliability of the testing process.

[0032] Furthermore, support platform 120 includes a first plate 121, a second plate 122, and a third plate 123, which are connected in sequence. Specifically, first plate 121 of support platform 120 is connected to workbench 110, while second plate 122, third plate 123, and first plate 121 collectively form a receiving groove 132, which can be used to assemble other components. Thus, the three-plate structure of support platform 120 forms a sturdy support frame, which not only ensures the stability of the test device during operation but also effectively resists the impact force generated during vibration testing, reducing the risk of deformation or damage caused by vibration.

[0033] Please continue reading Figure 6 , Figure 6 13 is a top view of the test device provided in an embodiment of the present application. In this embodiment, the support platform 120 includes a plurality of first reinforcing ribs 124, and the plurality of first reinforcing ribs 124 are arranged in the accommodating groove 132 and are respectively connected to the first plate 121, the second plate 122 and the third plate 123. The plurality of first reinforcing ribs 124 not only improve the load-bearing capacity and vibration resistance of the test device, but also improve the overall structural strength and rigidity of the device through the connection with the first plate 121, the second plate 122 and the third plate 123, thereby ensuring the accuracy and reliability of the vibration test. During the vibration test, the battery pack and its accessories will generate large dynamic loads, and the presence of the reinforcing ribs effectively disperses these loads, preventing the device from being deformed or damaged due to overload.

[0034] In one embodiment, the support platform 120 further includes a plurality of second reinforcing ribs 125 disposed within the receiving groove 132 and connected to the second plate 122. Specifically, the second reinforcing ribs 125 may extend along the support frame and intersect with the first reinforcing ribs 124. This intersecting connection not only increases the complexity of the internal structure of the support platform 120 but also further enhances the stability of the overall structure through force transmission at the intersection. The second reinforcing ribs 125 may also be annular, surrounding the receiving groove 132 or key locations of the support platform 120 and connected to the first reinforcing ribs 124. This annular design facilitates uniform stress distribution and reduces local stress concentration, thereby improving the vibration resistance and service life of the support platform 120. Furthermore, the annular second reinforcing ribs 125 provide additional support for the first reinforcing ribs 124, allowing the two to form a more robust and stable overall structure.

[0035] Please continue reading Figure 7 , Figure 7It is a schematic diagram of the three-dimensional structure of the support frame 200 provided in this application. In this embodiment, the support frame 200 includes a bottom plate 210, a side plate 220 and an end plate 230, and the bottom plate 210, the side plate 220 and the end plate 230 are jointly arranged to form a limiting groove 240. Among them, the bottom plate 210 is fixedly connected to the support platform 120 to ensure that the support frame 200 can stably withstand the weight and vibration load of the battery pack during the vibration test. The side plates 220 and the end plates 230 are arranged on the adjacent two side edges of the bottom plate 210, and the side plates 220 extend along the length direction of the bottom plate 210. The end plates 230 are perpendicular to the bottom plate 210 and the side plates 220, forming the boundary of the support frame 200.

[0036] The beneficial effect of adopting the above-mentioned further solution is that, in actual application, the utility model is provided with baffles in the length and width directions of the battery pack, which enhances the stability of the battery pack during the test. During the vibration test, the battery pack is often subjected to vibration and impact forces from all directions, and the provision of the baffles can effectively prevent the battery pack from sliding or shifting under the action of these forces, thereby ensuring the accuracy and reliability of the test results. In addition, during transportation, the battery pack may encounter adverse conditions such as bumps and shaking, which can easily cause the battery pack to fall or be damaged. By providing baffles in the utility model, we can significantly reduce this risk, protect the battery pack from damage by external shocks and vibrations, and ensure its safety and integrity during transportation.

[0037] Please return to Figures 2 to 4 , Figure 2 is a schematic cross-sectional view of the test device provided in an embodiment of the present application along the direction of the support frame, Figure 3 yes Figure 2 A magnified image in the middle. Figure 4 yes Figure 2 Enlarged view at point B in the middle. In one embodiment, the fixing assembly 300 provided by the present invention includes a fixing member 310 and a positioning pin 320. Specifically, a fixing hole 211 is provided at the end of the base plate 210, that is, on the side away from the end plate 230. These fixing holes 211 are used to allow the fixing member 310 to pass through and thereby achieve a stable connection with the battery pack, ensuring that the battery pack can be firmly fixed on the test device during the vibration test to avoid displacement or falling off due to vibration. At the same time, a positioning pin 320 is provided on the end plate 230. During the assembly process, the positioning pin 320 can be quickly and accurately inserted into the corresponding position of the battery pack, which not only improves the positioning accuracy of the battery pack on the device, but also enhances its stability in a vibration environment, and prevents potential risks caused by position offset.

[0038] During the actual assembly process, the battery pack is first placed on the support table 120 to ensure that the bottom of the battery pack is in full contact with the surface of the support table 120. Then, according to the positioning holes or notches on the battery pack, it is docked with the positioning pins 320 on the end plate 230. The positioning pins 320 can not only provide preliminary positioning for the battery pack in the horizontal direction, but also limit the lateral movement of the battery pack during the vibration test to a certain extent. Finally, according to the position of the fixing hole 211, the angle and position of the battery pack are adjusted so that the other end can be accurately aligned with the fixing hole 211. When the battery pack is completely aligned with the fixing hole 211, use the fixing parts 310 (such as bolts, nuts, etc.) to pass through the fixing hole 211 and tighten them to tightly connect the battery pack to the support frame 200.

[0039] Please continue reading Figure 8 , Figure 8 It is a cross-sectional schematic diagram of the test device base 100 provided in an embodiment of the present application. In this embodiment, the test device also includes a support member 400, which is arranged on the support platform 120 and abuts against the side of the side plate 220 away from the limiting groove 240. In actual applications, when faced with strong vibrations, the support member 400 can provide additional supporting force to prevent the side plate 220 from unnecessary deformation or displacement due to vibration. At the same time, the support member 400 also plays a role in dispersing the vibration load, transferring part of the vibration energy to the more stable support platform 120 structure, thereby protecting the battery pack and the test device itself from damage.

[0040] Please continue reading Figure 9 and Figure 10 , Figure 9 is a structural diagram of the test device base provided in an embodiment of the present application, Figure 10 yes Figure 9 Enlarged view of point C in the middle. In this embodiment, the testing device also includes a fastener 500. Specifically, an adjustment slot 126 is defined in the support platform 120. The adjustment slot 126 extends away from the workbench 110, providing flexible space for the installation and adjustment of the fastener 500. The fastener 500 is used to penetrate the adjustment slot 126 and tightly connect to the support frame 200, thereby ensuring the stability and reliability of the various components of the vibration testing device.

[0041] During assembly, the position of fastener 500 in adjustment slot 126 can be flexibly adjusted based on actual needs and test conditions. This adjustment process typically involves the following steps: First, loosen the fastener 500 from its initial position, allowing it to move freely within adjustment slot 126; second, gently push or pull the fastener 500 along adjustment slot 126 to the desired distance between support platform 120 and support frame 200, allowing it to slide to the appropriate position; and finally, re-tighten the fastener 500 to ensure it is securely locked in its new position within adjustment slot 126. By adjusting the position of fastener 500 in adjustment slot 126, the distance between support platform 120 and support frame 200 can be fine-tuned to achieve optimal testing results. This not only improves the flexibility and adaptability of the vibration test apparatus, but also ensures stable testing performance when testing battery packs of varying sizes, weights, or vibration characteristics. Furthermore, the coordinated use of fastener 500 and adjustment slot 126 simplifies the assembly and disassembly process, improving work efficiency.

[0042] Please continue reading Figure 11 , Figure 11 It is a cross-sectional schematic diagram of a test device base 100 provided in another embodiment of the present application. In this embodiment, the support frame 200 is configured as a stepped step 600. In actual application, the sizes of battery packs are diverse, and the design of the stepped step 600 can achieve compatibility with battery packs of different sizes and shapes. At the same time, when the battery pack is placed on the stepped support frame 200, its bottom or side will naturally contact the corresponding position of the stepped step 600, which can achieve dual positioning of the battery pack in the vertical and horizontal directions. This positioning method is not only simple and effective, but also can significantly reduce the sliding or offset phenomenon of the battery pack during the vibration test. It ensures that the battery pack can be stably fixed in the test position and is not affected by the vibration environment, thereby ensuring the accuracy and reliability of the test results.
