Detailed Implementation

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figures 1-3 As shown, this application provides an automotive headlight air tightness testing device, including a bracket 1 and a workbench 2 fixedly installed on the upper end of the bracket 1. In order to facilitate the testing of automotive headlight air tightness, a testing mechanism 5 is provided on the workbench 2. The testing mechanism 5 includes a water tank 54 fixedly installed on the workbench 2 at the middle position. The water tank 54 is used to place automotive headlights and testing liquid used for testing.

[0034] Meanwhile, in order to complete the test smoothly, a column 55 is fixedly installed on the workbench 2, and a fixing plate 56 is fixedly installed on the upper end of the column 55. A water tank 50 is fixedly installed on the fixing plate 56, and a water inlet pipe 51 is fixedly installed on the water tank 50. The other end of the water inlet pipe 51 is connected to the water tank 54 so that the test liquid can be introduced into the water tank 54. A drain pipe 52 is fixedly installed at the bottom of the water tank 54, and the drain pipe 52 is also connected to the water tank 54 so that the test liquid after the test can be discharged from the water tank 54.

[0035] In order to keep the car headlights stable during testing, a fixing mechanism 3 is provided at both ends of the water tank 54. The fixing mechanism 3 is used to fix the car headlights. The fixing mechanism 3 includes a sliding rod 34 that is slidably disposed at both ends of the water tank 54. A pressure plate 33 is fixedly disposed at one end of the sliding rod 34 inside the water tank 54. The pressure plate 33 is used to directly contact the car headlights.

[0036] Meanwhile, fixed seats 30 are fixedly installed on both sides of the water tank 54 on the workbench 2, and hydraulic cylinders 31 are fixedly installed on the fixed seats 30. The output end of the hydraulic cylinder 31 is fixedly connected to the sliding rod 34. Thus, starting the hydraulic cylinder 31 can push the sliding rod 34 to drive the pressure plates 33 on both sides to move closer and further away from each other, thereby fixing the car lights inside the water tank 54.

[0037] During testing, simply place the headlight into the water tank 54, pour in the appropriate test liquid, and ensure that the headlight is completely immersed in the test liquid. At the same time, inflate the headlight with air to make its internal air pressure higher than the external environment. If no bubbles are generated on the surface of the test liquid, the headlight's airtightness is qualified; if bubbles appear on the surface of the test liquid, the headlight's airtightness is unqualified.

[0038] like Figure 1 and Figure 4 As shown, in order to dry the car headlights in time after the inspection, a drying mechanism 6 is provided on the fixed plate 56. The drying mechanism 6 includes multiple sets of cylinders 60 fixedly installed on the fixed plate 56. The output end of the cylinder 60 extends through the fixed plate 56 to the lower end and is fixedly installed with a mounting bracket 64. Thus, starting the cylinder 60 can push the mounting bracket 64 to move vertically up and down.

[0039] Meanwhile, a mounting box 61 is fixedly installed between the mounting brackets 64, and an electric heating wire 62 is fixedly installed inside the mounting box 61. The electric heating wire 62 is used to provide heat energy for drying the car headlights.

[0040] Furthermore, a fan 63 is provided at the upper end of the mounting box 61. The fan 63 is used to conduct the heat energy generated by the heating wire 62 through the mounting box 61 to the surface of the car headlight.

[0041] Once the test is complete, simply activate cylinder 60 to push mounting bracket 64 and mounting box 61 against the car headlight until it is in the correct position. Then, activate heating wire 62 to provide heat energy, which is then blown onto the surface of the car headlight by fan 63 until the surface moisture is dried.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
