Therefore, related experimental testing equipment must also reflect universality, which is crucial for cost savings, improved work efficiency, and shortened project cycles. Thus, a universal vibration fixture for bottom-fixed standard boxes, without requiring a long procurement and manufacturing cycle, ensures a fixed connection for each standard box under vibration conditions through the installation positions of the mounting plates and the dimensions of the mounting holes in the vibration pack, achieving the fixture's universality. Repeated operation with the same fixture allows experimental operators to become increasingly proficient, reducing work time and improving efficiency. Furthermore, the fixture uses a simple connection structure for easy loading and unloading, further enhancing work efficiency.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] This application aims to address the following issues in vibration experiments involving bottom-fixed standard boxes: long manufacturing cycles for vibration fixtures; complex disassembly and disassembly of fixtures when fixing the standard box vibration pack, resulting in low work efficiency; and difficulties in storage, high manufacturing costs, and resource waste caused by the wide variety of fixtures.

[0034] This application provides a battery pack vibration fixture, referenced... Figure 1 The tooling body 1 includes a tooling body 1 on which a fixed mounting component is installed.

[0035] The tooling body 1 is surrounded by multiple first-fixed parts 7, and the tooling body 1 is connected to the vibration table through the first-fixed parts 7.

[0036] The fixed installation component is equipped with a second fixing part 6 and a third fixing part 8. The fixed installation component is connected to the tooling body 1 through the second fixing part 6, and the fixed installation component is connected to the battery pack body through the third fixing part 8.

[0037] This application, when using a universal vibration fixture for a bottom-fixed standard box, achieves universality by ensuring a fixed connection for each battery pack under vibration conditions through the installation position of the fixed mounting components and the mounting hole size of the battery pack body, without requiring a long procurement and manufacturing cycle. Repeated operation with the same fixture allows experimental operators to become increasingly proficient, reducing work time and improving work efficiency. Furthermore, the fixture uses a simple connection structure, facilitating loading and unloading, further enhancing work efficiency.

[0038] In one embodiment of this utility model, reference is made to... Figure 1 The fixed installation assembly includes a first fixed installation plate 2, a second fixed installation plate 3, and a third fixed installation plate 4;

[0039] Two sets of fixed mounting plates 1 2 are set at both ends of the tooling body 1, fixed mounting plates 2 3 are set in the middle of the tooling body 1, and two sets of fixed mounting plates 3 4 are symmetrically set at both ends of fixed mounting plates 2 3.

[0040] The main body of the battery pack is mounted on the first mounting plate 2 and the second mounting plate 3, or on the second mounting plate 3 and the third mounting plate 4.

[0041] By dividing the mounting assembly into five parts—one mounting plate 2, two mounting plates 1, and two mounting plates 3—and then selecting the corresponding three parts to connect according to the size of the battery pack body, it is convenient to install battery pack bodies of different sizes.

[0042] In one embodiment of this utility model, two sets of lifting rings 5 ​​are installed on the tooling body 1, and the two sets of lifting rings 5 ​​are respectively located at both ends of the tooling body 1.

[0043] By setting lifting rings 5 ​​at both ends, the tooling body 1 can be transferred and assembled.

[0044] In one embodiment of this utility model, each set of fixed mounting plates 34 includes two;

[0045] Each set of mounting plates 3 4 includes two adjacent plates, which can be further selected and connected to a more suitable position according to the size of the battery pack body, thereby further ensuring the stability of the connection.

[0046] In one embodiment of this utility model, reference is made to... Figure 2 The mounting assembly has a countersunk hole at the location of the second fixing member 6, which matches the second fixing member 6. The countersunk hole is designed so as not to affect the installation of the battery pack body.

[0047] In one embodiment of this utility model, reference is made to... Figure 1 and Figure 2 The fixed mounting component has a second mounting hole, and the tooling body 1 has a plurality of first mounting holes evenly distributed on it; the spacing between adjacent first mounting holes is equal to the spacing between the second mounting holes on the fixed mounting component.

[0048] It can adjust the installation position of the fixed mounting components along the length of the tooling body 1.

[0049] In one embodiment of this utility model, the tooling body 1 has a connecting hole that matches the first fixing component 7 at the setting position of the first fixing component 7.

[0050] The fixture body 1 is connected to the vibration table by bolts through the connection holes, and can be reasonably configured according to the size and weight of the specific battery pack body.

[0051] In one embodiment of this utility model, the second fixing member 6 and the third fixing member 8 are internal hex bolts.

[0052] Using hexagonal socket head cap screws, the mounting assembly and fixture body 1 are connected via mounting holes 1, 2, and countersunk holes, with the hexagonal head lower than the upper surface of the mounting assembly. Corresponding mounting holes are machined according to the dimensions of the battery pack mounting points. The battery pack body and the mounting assembly are connected via mounting holes on fixture body 1 and corresponding mounting holes in the mounting assembly.

[0053] In one embodiment of this utility model, the two sets of lifting rings 5 ​​include four rings, which are distributed at the four corner positions of the tooling body 1.

[0054] By distributing four lifting rings 5 ​​at the four corners, they are used for on-site transportation, pre-vibration assembly with the battery pack body, and use on and off the vibration table.

[0055] In one embodiment of this utility model, the tooling body 1 and the fixing mounting component are made of aluminum.

[0056] The body is made of aluminum sheet, which not only gives it sufficient strength and rigidity, but also makes it smooth, which facilitates the installation of the top mounting plates and the bottom fixing to the vibration table; and prevents red rust from damaging the tooling, so as to facilitate storage.

[0057] Specific work process:

[0058] like Figure 3 As shown, the battery pack body is a standard box 9. The standard box battery pack is a platform-based battery pack. The standard box 9 is fixed by the No. 3 fastener 8 on the fixed mounting plate 2 and the fixed mounting plate 3.

The internal hex bolts pass through the mounting holes of fixing mounting plate 3 4 and fixing mounting plate 2 3 from bottom to top and are fixedly connected to the corresponding mounting holes on standard box 2 10.

[0061] like Figure 6 As shown, the battery pack body is standard box four 12, and standard box two 10 is fixed by fixing mounting plate three 4 and fixing mounting plate two 3 with fixing part number three 8.

The internal hex bolts pass through the mounting holes of fixing mounting plate three 4 and fixing mounting plate two 3 from bottom to top and are fixedly connected with the corresponding mounting holes on standard box two 10.

[0063] In standard box 2 10 and standard box 3 11, the fixed mounting plate 3 4 is one of the two fixed mounting plates 3 4 that are closer to both ends of the tooling body 1; in standard box 4 12 and standard box 5 13, the fixed mounting plate 3 4 is one of the two fixed mounting plates 3 4 that are closer to the middle of the tooling body 1.
