Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to an external airtightness testing fixture for new energy storage boxes. Background Technology

[0002] Currently, the energy storage assembly is the power source for new energy vehicles, and its performance directly impacts the overall vehicle safety. Because the energy storage assembly is located under the vehicle body, especially when the vehicle is submerged in water, it must be able to withstand a certain water pressure. Water ingress will severely affect its functionality and may even cause short circuits or fires. Therefore, the airtightness of the energy storage assembly is a crucial safety feature for pure electric vehicles.

[0003] Existing insert-type tooling requires water nozzles to be inserted into the cold plate of the energy storage tank, which is complicated and time-consuming. In addition, insert-type tooling may scratch the cold plate, causing coolant leakage due to seal failure, reducing the service life of the energy storage tank. It cannot meet the increasingly high requirements of modern industry and production for airtightness testing tooling.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0037] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0038] like Figure 1-4 As shown, this application discloses an external airtightness testing fixture for a new energy storage box, comprising a first steel ring sleeve 10 and a second steel ring sleeve 20. Specifically, the first steel ring sleeve 10 includes a first cylinder 11 and four axially extending first spring pieces 12 evenly distributed in a ring on the radial outer edge of the first cylinder 11, forming a non-penetrating first cavity 13. A first rubber sleeve 30 is disposed inside the first cavity 13, and a first steel ring clamping ring 70 is fitted over the four first spring pieces 12. The second steel ring sleeve 20 includes a second cylinder 21 and four axially extending second spring pieces 22 evenly distributed in a ring on the radial outer edge of the second cylinder 21, forming a non-penetrating second cavity 23. A second rubber sleeve 40 is disposed inside the second cavity 23, and a second steel ring clamping ring 80 is fitted over the four second spring pieces 22.

[0039] The second steel ring sleeve 20 has a first air passage 24 inside, and the second rubber sleeve 40 has a second air passage 42 that communicates with the first air passage 24. The air inlet 2411 of the first air passage 24 is connected to an inflation pipe 50, and the second air passage 42 has an air outlet 421. During operation of this application, if... Figure 5As shown, the first steel ring clamp 70 seals the first rubber sleeve 30 onto the water inlet of the energy storage tank, and the second steel ring clamp 80 seals the second rubber sleeve 40 onto the water outlet of the energy storage tank. An airtightness tester is connected to the air inlet of the air inlet tube to perform an airtightness test on the energy storage tank. The air inlet tube can be quickly connected to the cold plate water inlet through the interface without disassembling the tank or cold plate structure, which greatly shortens the test preparation time, is convenient to operate, avoids scratching the cold plate of the energy storage tank, has high test safety, and extends the service life of the energy storage tank.

[0040] In a preferred embodiment, each of the first spring pieces 12 has a first arc-shaped stop 121 extending radially outward from its outer radial edge, and each of the second spring pieces 22 has a second arc-shaped stop 221 extending radially outward from its outer radial edge. By providing the first arc-shaped stop 121 and the second arc-shaped stop 221 on the outer radial edges of the first spring pieces 12 and the second spring pieces 22 respectively, the first steel ring clamp ring 70 and the second steel ring clamp ring 80 are prevented from easily slipping off the first steel ring sleeve 10 and the second steel ring sleeve 20 respectively.

[0041] Specifically, the first air passage 24 includes a radial air passage 241 and an axial air passage 242 connected to the radial air passage 241. The radial air passage 241 has the air inlet 2411. An air inlet adapter 60 is also provided between the air inlet 2411 and the air inlet 2411 to achieve a stable connection between the air inlet 50 and the air passage 24.

[0042] Specifically, each end of the first steel ring clamp 70 has a first protrusion 71 formed thereon, and the two first protrusions 71 are arranged opposite to each other. A first locking arm 72 is hinged to one of the first protrusions 71. The first locking arm 72 has a first strip-shaped opening with a width greater than the width of the two first protrusions 71. The first locking arm 72 can fix or separate the two first protrusions 71. Since the width of the first strip-shaped opening of the first locking arm 72 is greater than the width of the two first protrusions 71, the two first protrusions can be housed in the first strip-shaped opening, thereby fixing the two first protrusions by the first locking arm 72, and also making the first... A steel ring clamp 70 can fasten the first steel ring sleeve 10 and the first rubber sleeve 30 to the water inlet of the energy storage tank; both ends of the second steel ring clamp 80 are formed with a second protrusion 81, and the two second protrusions 81 are arranged opposite each other. A second locking arm 82 is hinged to one of the second protrusions 81. The second locking arm 82 can fix or separate the two second protrusions 81. The second locking arm 82 is provided with a second strip-shaped opening with a width greater than the width of the two protrusions 81. Similarly, the second steel ring clamp 80 can fasten the second steel ring sleeve 20 and the second rubber sleeve 40 to the water outlet of the energy storage tank.

[0043] Specifically, the second rubber sleeve 40 is connected to the second steel ring sleeve 20 by a connecting bolt 41, so that the second rubber sleeve and the second steel ring sleeve are fixedly connected together.

[0044] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, convenient operation, and high testing safety.

[0045] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
