[0032] like Figure 1-4As shown, this embodiment proposes a battery tray airtightness testing fixture, including a workbench 1. A rectangular frame 2 and a U-shaped sealing gasket 3 are fixedly installed on the top of the workbench 1. A battery tray 4 is placed on the top of the U-shaped sealing gasket 3. A water tank 5 is installed on the workbench 1. A water pump 6 is installed on one side of the water tank 5. A water inlet pipe 7 is fixedly installed between the water inlet end of the water pump 6 and the water tank 5. When the water pump 6 is started, water is drawn out of the water tank 5 through the water inlet pipe 7. A water injection pipe 8 is fixedly installed at the water outlet end of the water pump 6. The end of the water injection pipe 8 away from the water pump 6 is located inside the rectangular frame 2. The water drawn out is injected into the rectangular frame 2 through the water injection pipe 8, so that the battery tray 4 is completely submerged in water. A [missing information - likely a device or equipment] is installed on the lower inner surface of the workbench 1. Air pump 9 has a connecting pipe 10 fixedly installed at its air inlet end. When air pump 9 is started, external air is drawn in through the connecting pipe 10. Air pump 9 has an air injection pipe 11 fixedly installed at its air outlet end. The end of air injection pipe 11 away from air pump 9 is located inside rectangular frame 2. Gas is injected into the sealed cavity formed by the top of workbench 1 and the inner surface of battery tray 4 through air injection pipe 11. If there is a problem with the airtightness of battery tray 4, bubbles will rise in the water inside rectangular frame 2. Drain pipe 12 is fixedly installed on the upper inner surface of workbench 1. Drain valve 13 is installed on drain pipe 12. The specific location of the airtightness problem of battery tray 4 can be determined by observing the position of the bubbles generated in the water inside rectangular frame 2.
[0033] like Figure 1 and Figure 2 As shown, an L-shaped frame 14 is fixedly connected to the back of the workbench 1. A cylinder 15 is fixedly connected to the lower surface of the L-shaped frame 14. An I-shaped pressure plate 16 is fixedly installed on the push rod end of the cylinder 15. When the cylinder 15 is activated, the I-shaped pressure plate 16 is moved down by the cylinder 15, so that it contacts the outer surface of the battery tray 4 and fixes the battery tray 4, so that the top of the workbench 1 and the inner surface of the battery tray 4 form a sealed cavity.
[0034] like Figure 2 As shown, the lower surface of the L-shaped frame 14 is equipped with heaters 17 symmetrically distributed with respect to the cylinder 15. The two heaters 17 blow hot air onto the surface of the battery tray 4 to quickly dry the water stains on the outer surface of the battery tray 4.
[0035] like Figure 2 and Figure 3 As shown, a water inlet pipe 18 is fixedly connected to the water tank 5, and the end of the drain pipe 12 away from the workbench 1 is connected to the water tank 5. Water can be easily added to the water tank 5 through the water inlet pipe 18.
[0036] like Figure 1 As shown, the water pump 6 is located to the left of the air pump 9, and the water pump 6 is fixedly installed on the lower inner surface of the workbench 1.
[0037] like Figure 3 As shown, the spiral-shaped sealing gasket 3 is located inside the rectangular frame 2, and the spiral-shaped sealing gasket 3 is tightly fitted to the inner wall of the rectangular frame 2.
[0038] like Figure 1 and Figure 3 As shown, the battery tray 4 is attached to the U-shaped sealing gasket 3, and the rectangular frame 2 is made of transparent glass.
[0039] Specifically, when using this battery tray airtightness testing fixture: The battery tray 4 to be tested is placed upside down on top of the U-shaped sealing gasket 3. The cylinder 15 is activated, causing the I-shaped pressure plate 16 to move downwards, contacting the outer surface of the battery tray 4 and fixing it in place. This creates a sealed cavity between the top of the workbench 1 and the inner surface of the battery tray 4. The water pump 6 is then activated, drawing water from the water tank 5 through the suction pipe 7 and injecting it into the rectangular frame 2 through the injection pipe 8, completely submerging the battery tray 4 in water. Then, the air pump 9 is activated, drawing in external air through the connecting pipe 10 and injecting it into the space between the top of the workbench 1 and the battery tray 4 through the air injection pipe 11. If there is a problem with the airtightness of the battery tray 4, bubbles will rise in the water inside the rectangular frame 2, which is made of transparent glass. By observing the location of the bubbles in the water inside the rectangular frame 2, the specific location of the airtightness problem of the battery tray 4 can be determined, thus improving the accuracy of the airtightness test. After the airtightness test of the battery tray 4 is completed, the drain valve 13 is opened, and the water inside the rectangular frame 2 flows back into the water tank 5 through the drain pipe 12 for subsequent recycling, thus avoiding waste of water resources. Finally, hot air is blown onto the surface of the battery tray 4 by two heaters 17 to quickly dry the water stains on the outer surface of the battery tray 4.
[0040] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
