[0019] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0020] Example like Figure 1-3 As shown, a simple fixture for testing product leakage according to the present invention includes: a tray 1, an inflation head 4, and a sealing gasket 5. A product 6 is placed on the tray 1, and an inflation hole 7 is provided on the upper surface of the product 6. The inflation head 4 is installed on one side of the tray 1 through an inflation head moving device 3. The inflation head 4 can move up and down to connect or separate from the product inflation hole 7. A connector 8 is provided on one side of the product 6. The sealing gasket 5 is installed on the side of the tray 1 near the connector 8 through a sealing gasket moving device 2. The sealing gasket 5 can move closer to or away from the product 6 through the sealing gasket moving device 2. When the sealing gasket 5 is pressed against the product 6, the sealing gasket 5 can completely seal the connector 8.

[0021] The inflation head 4 and the sealing gasket 5 are installed on opposite sides of the tray 1. Generally, the inflation head 4 is installed on the left side of the tray 1 to continuously inflate the product 6 by connecting to the product inflation hole 7; the sealing gasket 5 is installed on the right side of the tray 1 to seal the connector 8 of the product 6.

[0022] The inflation head moving device 3 includes an inflation head handle and a handle mounting base. The handle mounting base is fastened to the tray 1. One end of the inflation head handle is movably connected to the handle mounting base, and the other end is movably connected to the inflation head 4.

[0023] The inflation head 4 includes a foldable inflation head. The top of the inflation head 4 is provided with an air inlet, and the outer side of the air inlet channel of the inflation head 4 is provided with threads. The inflation head handle is provided with a threaded hole that matches the threads, and the inflation head 4 moves up and down through the cooperation of the threads and the threaded hole.

[0024] The gasket moving device 2 includes a gasket moving rod, a gasket moving handle, and a gasket moving mounting base. The gasket moving handle is drivenly connected to the gasket moving rod, which can move axially. The gasket moving rod is drivenly connected to the gasket 5, allowing the gasket 5 to move closer to or further away from the connector 8. Generally, the operator needs to pry the gasket moving handle from the outer side to make the gasket 5 press against the connector 8.

[0025] The gasket moving rod is connected to the gasket 5 by multiple springs, which can act as a buffer when the gasket 5 and the product 6 are pressed together.

[0026] The movable gasket mounting base has mounting holes, and the tray 1 has multiple mounting holes, with the number of mounting holes exceeding the number of mounting holes. This creates multiple mounting positions for the movable gasket mounting base on the tray 1. Generally, the number of mounting holes is an integer multiple of the number of mounting holes.

[0027] The connector 8 of product 6 includes one or more connection ports, and the sealing gasket 5 includes a rectangular PU sealing gasket. All connection ports are embedded in the sealing gasket 5 to form a sealed connection.

[0028] The operation process of this application is as follows: The operator installs the sealing gasket 5 and the sealing gasket moving device 2 according to the position of the connector 8 of product 6, places product 6 on tray 1, pushes the sealing gasket 5 to the sealing area using the sealing gasket moving device 2, and seals the connector 8 with the sealing gasket 5. The operator then adjusts the inflation head 4 to the inflation area using the inflation head moving device 3, connects the inflation head 4 to the product inflation port 7, turns on the air source to continuously inflate product 6, drips liquid to check for leaks at the structural adhesive seal, and observes for air bubbles. After the operation is completed, the air source is turned off, and the sealing gasket 5 and inflation head 4 are reset using the sealing gasket moving device 2 and the inflation head moving device 3. Product 6 is then removed from tray 1.

[0029] This application requires an external air source to supply 0.1 MPa compressed air through a pressure reducing valve, which is then injected into the controller product via the inflation head 4. The connector 8 of the controller is then sealed using a sealing gasket 5. This application features a simple structure, convenient operation, and supports replacement of all models on the production line. After inflation and sealing are complete, leak detection fluid is sprayed onto the structural adhesive seal. If the seal fails, a large amount of foam will continuously be generated at the failure point, enabling rapid and accurate location of leaks in the vehicle integrated controller, effectively improving the production line yield and first-pass yield.

[0030] Variation Example Based on embodiment 1, the product 6 is provided with multiple connectors 8, and the tray 1 is correspondingly equipped with multiple sealing gaskets 5 and multiple sealing gasket moving devices 2. The multiple sealing gaskets 5 are respectively driven by the corresponding sealing gasket moving devices 2 to seal and connect with the corresponding connectors 8.

[0031] like Figure 4 As shown, the controller has two connectors 8, and correspondingly, the tray 1 is equipped with two sets of sealing gaskets 5 and a sealing gasket moving device 2. The two connectors 8 are sealed by the two sealing gaskets 5 respectively. After inflation and sealing are complete, leak detection fluid is sprayed onto the structural adhesive seal. If the seal fails, a large amount of foam will be continuously generated at the failure point. This enables rapid and accurate location of leaks in the vehicle integrated controller, effectively improving the yield rate and first pass rate of the production line.
