[0002] In the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:

[0003] Existing battery pack vibration tooling mainly uses welded frames or aluminum plate assembly structures, and most of the battery pack lifting ear fixing parts are fixed structures, which cannot be shared by battery packs of different specifications and sizes.

[0004] If the battery pack's dimensions, or the structure or position of the lifting lugs, change, new tooling must be fabricated to accommodate vibrations, or the original lifting lugs' welds must be cut and re-welded. However, repeated welding can cause the frame to deform, weakening it and rendering the tooling useless.

[0005] The existing welding vibration tooling has large welding deformation and high processing difficulty. After welding, stress concentration needs to be eliminated and the bottom surface flatness is difficult to control. At the same time, it is difficult to switch to other products for compatibility. Repeated cutting and welding will reduce the tooling accuracy and make it unusable.

[0006] Existing aluminum single-body vibration tooling is large in size and high in cost. If vibration tooling is required for battery packs of different structures or sizes, it will take up a lot of money and storage space, and cause a lot of pollution and waste of resources.

[0010] base plate;

[0011] The columns are slidably mounted on both sides of the base plate; the columns are connected to the base plate through a positioning mechanism;

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 4 A new type of battery pack vibration device comprises: a base plate 1; a column 2, which is slidably mounted on both sides of the base plate 1; the column 2 is connected to the base plate 1 through a positioning mechanism; a mounting plate 3, which is fixedly mounted on the column 2; a slide groove 22, a slide groove 22 is provided on the upper surface of the column 2; a lifting ear fixing plate 4, which is slidably mounted in the slide groove 22; the end of the lifting ear fixing plate 4 can be locked on the mounting plate 3. The X-direction position is changed by sliding the column 2 on the base plate 1, and the Y-direction position is changed by sliding the lifting ear fixing plate 4 on the column 2. The lifting ear of the battery pack is mounted on the lifting ear fixing plate 4 to fix the battery pack, which is convenient for subsequent vibration experiments. One tool is compatible with multiple battery packs to reduce the investment in vibration tooling, save storage space, and solve the problems of large deformation and high processing difficulty of the original welding tooling.

[0028] The positioning mechanism includes a series of mounting holes 11 provided on the base plate 1, and the column 2 is connected to the base plate 1 through bolts and the mounting holes 11. After the column 2 moves, the column 2 is fixed through the corresponding mounting holes 11.

[0029] A guide groove 12 is provided on the bottom plate 1 , and a slider 21 adapted to the guide groove 12 is provided on the column 2 . The slider 21 is a V-shaped block and plays a guiding role during the sliding process of the column 2 .

[0030] The mounting plate 3 is provided with a mounting groove 31, and the ear fixing plate 4 can be locked in the mounting groove 31. During the sliding process, the ear fixing plate 4 is fixed in position by the ear fixing plate 4 on the side. During the sliding process of the ear fixing plate 4, the mounting groove 31 plays a guiding role.

[0031] A waist-shaped hole 41 is further provided on the ear fixing plate 4. The battery pack can be adjustably installed in the waist-shaped hole 41, which can also play an adjustment role during the installation of the battery pack.

[0032] The lug fixing plate 4 has a series of different height specifications. You can choose a lug fixing plate 4 of different height specifications to achieve position change in the Z-axis direction to meet the usage requirements of battery packs of different specifications.

[0033] This solves the problems of large deformation, high processing difficulty, and poor processing precision of welding tooling. It also solves the problem that existing single-piece aluminum plate tooling is not compatible with multiple battery packs, reduces tooling capital investment and waste of management and storage space, while also reducing energy consumption and pollution.

[0034] Process steps:

[0035] 1. Make a tooling base with a slide groove to adjust the width direction of the battery pack column;

[0036] 2. Make a column with a slide groove and connect it to the base plate with bolts to adjust the position of the lifting lugs along the length of the battery pack;

[0037] 3. Make a sliding lug fixing plate with holes and connect it to the column slide groove through T-nuts and bolts to fix the battery pack lug;

[0038] 4. By making different lifting ear fixing plates and long waist holes on the lifting ear fixing plates, battery packs with different lifting ears can be universally used;

[0039] 5. In summary, the frame and the ear fixing plate can be adjusted in three directions: X, Y, and Z, so that one tool can be compatible with a variety of different battery packs.

[0040] After adopting the above structure, one tool is compatible with multiple battery packs, which reduces the investment in vibration tooling and saves storage space. At the same time, it solves the problem of large deformation and high processing difficulty of the original welding tooling.
