Currently, when conducting vibration tests on battery packs for packaging and transportation, a vibration fixture that can partially support the bottom of the battery pack is usually designed specifically for the battery pack.

[0003] Existing bottom-supporting vibration tooling is often only suitable for a specific type of battery pack, has poor versatility, and has complicated on-site assembly steps. There is also a problem of low installation precision of the bottom-supporting tooling and the battery pack. Utility Model Content

[0004] The purpose of the utility model is to provide a battery pack bottom supporting vibration tooling, which can solve the technical problems of poor versatility and low installation precision of the existing battery pack bottom supporting vibration tooling.

[0005] To achieve the above-mentioned purpose, the utility model designs a battery pack bottom support vibration tooling, which includes a vibration table, a battery pack mounting support, and a vibration tooling assembly. The battery pack mounting support and the vibration tooling assembly are both arranged at the upper end of the vibration table and located at the bottom of the battery pack. The vibration tooling assembly is a retractable structure.

[0006] As a preferred solution, the vibration tooling assembly includes a tooling body and a telescopic assembly. The tooling body is arranged on the vibration table, and the telescopic assembly is arranged on the tooling body.

[0007] As a preferred solution, the telescopic assembly includes a contact pressure head, a telescopic airbag, and an intake and exhaust valve. The contact pressure head is arranged above the telescopic airbag and contacts the bottom of the battery pack. The intake and exhaust valve is located on the side of the telescopic airbag.

[0008] Furthermore, a pressure sensor is installed at the bottom of the telescopic airbag.

It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of it.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] This utility model provides a battery pack bottom-supporting vibration fixture that can be freely adjusted on a vibration table to automatically complete the bottom-supporting action. This fixture has extremely high versatility while effectively improving assembly precision and efficiency. By optimizing the fixture's fixing form, this utility model achieves greater versatility. Furthermore, by adopting a pneumatic power form, it eliminates the need for additional laboratory equipment. The fixture automatically supports the battery pack, eliminating the tedious operations previously required by laboratory operators when installing the bottom-supporting vibration fixture.

[0026] like Figure 1 、 2 As shown, the present invention relates to a battery pack bottom supporting vibration tooling, comprising a vibration table 1, a battery pack mounting support 6, and a vibration tooling assembly. The battery pack mounting support 6 and the vibration tooling assembly are both arranged at the upper end of the vibration table 1 and located at the bottom of the battery pack. The vibration tooling assembly is a retractable structure.

[0027] like Figure 3 、 4As shown, the vibration tooling assembly includes a tooling body 2 and a telescopic assembly 8. The tooling body 2 is arranged on the vibration table 1, and the telescopic assembly 8 is arranged on the tooling body 2. The telescopic assembly 8 includes a contact pressure head 3, a telescopic airbag 4, and an intake and exhaust valve 5. The contact pressure head 3 is arranged above the telescopic airbag 4, and the contact pressure head 3 is in contact with the bottom of the battery pack. The intake and exhaust valve 5 is located on the side of the telescopic airbag 4. A pressure sensor is installed at the bottom of the telescopic airbag 4. A vertical mounting hole is provided at the top of the tooling body 2, and the telescopic assembly 8 is provided in the vertical mounting hole. A transverse valve hole is provided on the side of the tooling body 2, and the intake and exhaust valve 5 is provided in the transverse valve hole. The bottom of the tooling body 2 has a protrusion, and the protrusion matches the size of the mounting hole on the vibration table 1, so that the battery pack 7 can be fixed in the appropriate position of the vibration table 1.

[0028] The contact pressure head 3 is connected to the telescopic airbag 4 and assembled in the hole of the tooling body 2. The telescopic airbag 4 is connected to the inlet and exhaust valve 5 through the pre-opened hole in the tooling body 2. The external inflation tube can inflate and deflate the telescopic airbag 4 through the inlet and exhaust valve 5. The length of the telescopic airbag 4 is adjusted by inflating and deflation of the telescopic airbag 4. A pressure sensor is installed at the bottom of the telescopic airbag 4. Inflation is stopped when the pressure reaches the preset value, ensuring the bottoming effect while preventing the contact pressure head 3 from over-extension.

[0029] There are four battery pack mounting supports 6 symmetrically distributed on the vibration table 1 , and the tooling body 2 is set in the middle of the vibration table 1 .

[0030] Installation process:

[0031] The ends of the battery pack 7 are mounted on four battery pack mounting brackets 6, with the bottom of the battery pack 7 in direct contact with the telescopic assembly 8. The length of the telescopic airbag 4 is adaptively adjusted to suit the thickness of the battery pack 7, ensuring that the contact pressure head 3 is in full contact with the bottom of the battery pack 7. Specifically, the external inflation tube inflates and deflates the telescopic airbag 4 through the inlet and outlet valves 5. This adjustment adjusts the length of the telescopic airbag 4. A pressure sensor is installed at the bottom of the telescopic airbag 4, and inflation stops when the pressure reaches a preset value, ensuring a supportive effect while preventing the contact pressure head 3 from overextending.

[0032] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
