Description

Technical Field

[0001] This utility model relates to the field of airtight tooling technology, specifically to an airtight tooling for a new energy battery pack. Background Technology

[0002] With the continuous development of society, people are using cars more and more. Traditional cars cause a lot of pollution, and new energy vehicles are developing faster and faster. The battery pack is the main source of power for new energy vehicles. New energy battery packs can leak air during use. Therefore, it is necessary to conduct airtightness testing on the battery pack during the production process to prevent short circuits caused by air leakage and water seepage.

[0003] However, when existing airtight fixtures are used to perform airtightness tests on battery packs, the cover will expand and deform to varying degrees due to inflation. This deformation not only leads to inaccurate results for a single airtightness test, but also requires the deformed cover to be disassembled and reassembled for another airtightness test. Repeated tests can cause secondary or tertiary deformation of the cover, which increases testing time and labor costs.

[0004] In summary, the applicant has proposed an airtight tooling for a new energy battery pack. Utility Model Content

[0005] The purpose of this utility model is to provide an airtight tooling for new energy battery packs to save labor costs and improve network security. To achieve the above technical objective, the technical solution of this utility model is as follows:

[0006] A new energy battery pack airtight tooling, comprising:

[0007] The pressure arm structure has a sliding groove at the bottom and a through groove at the top that communicates with the sliding groove.

[0008] The sliding structure is provided in two sets, both of which are slidably connected to the sliding groove;

[0009] The connecting structure is also provided in two sets, which are respectively installed below the two sets of sliding structures;

[0010] A buffer element is disposed at the bottom of the pressure arm structure.

[0011] Furthermore, the sliding structure includes a slide plate slidably disposed in a slide groove, a slide rod mounted on top of the slide plate, and a locking component rotatably connected to the top of the slide rod via a through shaft.

[0012] Furthermore, the connection structure includes a sleeve installed on the bottom of the slide plate, a bolt threadedly connected to the sleeve, and a retaining plate disposed between the sleeve and the bolt.

[0013] Furthermore, the buffer is made of a special high-elasticity material.

[0014] After improvement, this utility model further produces the following beneficial effects:

[0015] 1. This tooling uses multi-point uniform compression of the battery pack casing to simulate the stress state under real-world usage conditions, reducing the risk of local deformation. It effectively solves problems such as unstable air pressure and casing deformation in existing technologies. In practical applications, it can significantly improve the accuracy and reliability of airtightness testing of new energy battery packs, reduce quality and safety accidents caused by testing, and lower testing costs, thus having significant economic and practical value.

[0016] 2. This fixture, through the combined action of its sliding and connecting structures, can be adapted to different battery pack models and ensures that the top cover maintains a stable shape during testing, avoiding multiple deformations caused by repeated disassembly and reassembly.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1-6 As shown, a new energy battery pack airtight tooling includes:

[0026] The pressure arm structure 1 has a sliding groove at the bottom and a through groove at the top that communicates with the sliding groove.

[0027] Sliding structure 2, wherein two sets of sliding structure 2 are provided, and both are slidably connected to the sliding groove;

[0028] The connecting structure 3 is also provided in two sets, which are respectively installed below the two sets of sliding structures 2;

[0029] Buffer 4 is disposed at the bottom of the pressure arm structure 1.

[0030] It should be noted that when installing this fixture, simply place the pressure arm structure 1 on the battery pack, then adjust the distance of the connecting structures 3 on both sides inward / outward through the sliding structure 2 so that the connecting structures 3 engage with the lifting lugs of the battery pack, and finally complete the fixing.

[0031] In addition, the cooperation between the sliding structure 2 and the connecting structure 3 enables this fixture to be adapted to different battery pack models, ensuring that the top cover maintains a stable shape during testing and avoiding multiple deformations caused by repeated disassembly and assembly.

[0032] The sliding structure 2 includes a slide plate 21 slidably disposed in a slide groove, a slide rod 22 installed on the top of the slide plate 21, and a clamp 23 rotatably connected to the top of the slide rod 22 via a through shaft.

[0033] It should be noted that, depending on the battery pack model, the distance between the two skateboards 21 is adjusted to complete the width adjustment of the connecting structure 3, so that it engages with the hanging lug of the battery pack. After adjusting to the appropriate position, the clip 23 is pushed down to press the clip 23 into the receiving groove opened above the pressure arm structure 1. The front end of the clip 23 is an elastic buckle, which completes the fixation of the skateboard 21 through elastic action.

[0034] The connection structure 3 includes a sleeve 31 installed at the bottom of the slide plate 21, a bolt 32 threadedly connected to the sleeve 31, and a clamping plate 33 disposed between the sleeve 31 and the bolt 32.

[0035] It should be noted that by adjusting the sliding structure 2, one end of the clamping plate 33 will engage with the lifting lug of the battery pack. At this time, the bolt 32 is tightened to complete the fixing of the pressure arm structure 1. At the same time, the height of the battery pack is different, that is, the distance between the sleeve 31 and the bolt 32 is different. Therefore, by cooperating the sleeve 31 and the bolt 32, the fixing of the pressure arm structure 1 is completed and the height of different battery pack models can be adjusted.

[0036] In addition, by fixing the pressure arm structure 1, the pressure arm structure 1 is tightly fitted to the box cover, providing a uniform and stable support force for the box cover. During the airtightness test, even if the box cover is subjected to inflation pressure, the support of the pressure arm structure 1 can effectively limit the deformation of the box cover, ensuring the stability of the box cover's shape, thereby improving the accuracy of the airtightness test.

[0037] The buffer 4 is made of a special high-elasticity material.

[0038] It should be noted that the main purpose of buffer 4 is to prevent excessive pressure from impacting the battery pack cover.

[0039] The specific working method is described below using specific embodiments: Example 1

[0040] Adjust the distance between the two skateboards 21 according to the different battery pack models to complete the width adjustment of the connecting structure 3, so that it can engage with the hanging lug of the battery pack. After adjusting to the appropriate position, push the clip 23 downward to press the clip 23 into the receiving groove opened on the upper part of the pressure arm structure 1. The front end of the clip 23 is an elastic buckle, which fixes the skateboard 21 through elastic action. Example 2

[0041] Tighten bolt 32 to complete the fixing of the pressure arm structure 1. At the same time, the height of the battery pack is different, that is, the distance between the sleeve 31 and the bolt 32 is different. Therefore, by cooperating with the sleeve 31 and the bolt 32, the fixing of the pressure arm structure 1 is completed, and the height of different battery pack models can be adjusted. By fixing the pressure arm structure 1, the pressure arm structure 1 is made to fit tightly with the box cover, providing uniform and stable support for the box cover. During the airtightness test, even if the box cover is subjected to inflation pressure, the support of the pressure arm structure 1 can effectively limit the deformation of the box cover, ensure the shape stability of the box cover, and thus improve the accuracy of the airtightness test.

[0042] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
