[0002] In the field of automotive technology, automotive lighting is an important component of automobiles, and automotive lighting must undergo airtightness testing before leaving the factory.

[0003] Chinese utility model patent, authorized announcement number CN209085866U, discloses an airtightness testing device for automotive lamps. This device uses a pressing cylinder to press a pressing structure onto the lamp, vents air into the airtightness testing frame through an air inlet, and observes the value of the air pressure gauge to test the airtightness of the lamp. This utility model has a novel structure and is easy to operate.

[0004] The above solution addresses the technical problems raised in the background section, but in practical applications, it still has certain shortcomings, such as:

[0006] 2. In the above-mentioned device, the automotive lamp to be tested is placed on the lamp placement plate. The lamp placement plate will come into contact with the surface of the automotive lamp, which may block the leakage of the automotive lamp, thereby reducing the detection accuracy. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The detection structure in this solution is used to test the airtightness of automotive headlights.

[0032] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: an automotive lighting detection structure, including a detection box 1, a box door 101 and a controller. At least one partition is fixed inside the detection box 1, and the partition divides the inner cavity of the detection box 1 into multiple detection chambers. After the box door 101 is closed, each detection chamber is in a closed state. In this solution, the number of partitions is set to one, thus forming two detection chambers.

[0033] Each detection chamber is equipped with a placement plate 5. The top of the placement plate 5 has a placement groove 501, and the bottom of the placement groove 501 has several through holes 502. The through holes 502 can prevent the placement groove 501 from blocking the bottom of the car lamp due to contact, thereby improving the detection accuracy. Furthermore, a pushing component is provided at the bottom of the placement plate 5. The pushing component can vertically push the car lamp placed in the placement groove 501, so that the car lamp can be flipped. This further prevents the placement groove 501 from blocking the bottom of the car lamp due to contact, thereby further improving the detection accuracy.

[0034] like Figure 3 and Figure 4 As shown, the pushing assembly includes a vertical tube 703 fixed to the bottom of the placement groove 501, a push rod 704 movably inserted into the vertical tube 703, and a rotating shaft 701 movably connected to the bottom of the detection box 1. Several cams 702, equal in number to the push rods 704, are fixed on the shaft of the rotating shaft 701. The push rods 704 contact the cams 702. Thus, when the rotating shaft 701 is rotated, the rotation of the cams 702 drives the push rods 704 to move up and down along the inner wall of the vertical tube 703, thereby pushing the bottom of the automotive lamp and causing the automotive lamp to shift, preventing the placement groove 501 from blocking the leakage point of the automotive lamp due to contact with the bottom of the automotive lamp.

[0035] like Figure 2 As shown, a testing component 2 is provided on the back of the testing box 1, and the airtightness of the automotive lamps is tested through the testing component 2.

[0036] Specifically, the detection component 2 includes a pressure sensor 3 fixed to the inner wall of the detection chamber 1. Each detection chamber is fixedly connected to an air inlet branch pipe. A first solenoid valve 202 is connected to the body of the air inlet branch pipe. An air inlet main pipe 201 is fixedly connected between the air inlet branch pipes. A pump pipe is fixedly connected to the body of the air inlet main pipe 201. An air pump 203 is connected to the air pump pipe. Compressed gas is injected into each detection chamber through the air pump 203. In this scheme, the air pump 203 fills the detection chamber with compressed air to 30 kPa.

[0037] Example 2: To safely depressurize the detection chambers, based on Example 1, the detection component 2 in this example further includes an exhaust pipe 204 connected to each detection chamber. The bottom of the exhaust pipe 204 is fixedly connected to an exhaust pipe 205. Since the exhaust port of the exhaust pipe 205 is vertically downward, it can prevent high-pressure gas from being directly sprayed onto the workers, thus improving the safety of depressurization. A second solenoid valve 206 is connected to the body of the exhaust pipe 205. The first solenoid valve 202, pressure sensor 3, air pump 203, and second solenoid valve 206 are all electrically connected to the controller.

[0038] Example 3: To facilitate placing the automotive lamps in the placement slot 501 of the placement plate 5, based on Example 1 or Example 2, guide rails 4 are fixed on both the side of the test box 1 and the side of the partition. The placement plate 5 is movably inserted between the two guide rails 4. When placing the automotive lamps, the placement plate 5 can be pulled out of the test box 1.

[0039] Example 4: In order to control the moving distance of the placement plate 5 and prevent the placement plate 5 from falling off the guide rail 4, based on Example 3, at least one limiting member 6 is provided between the placement plate 5 and the inner wall of the detection box 1.

[0040] Among them, such as Figure 3 and Figure 5 As shown, the limiting member 6 includes an insertion rod 602 movably connected to the placement plate 5 and a socket tube 601 movably connected to the inner wall of the detection chamber 1. The socket tube 601 is movably inserted into the insertion rod 602. A protrusion 603 adapted to the socket tube 601 is fixed at the end of the insertion rod 602. An annular pressure plate 604 adapted to the insertion rod 602 is fixed at the end of the socket tube 601. It can be seen that, in order to prevent the air pressure in the detection chamber from pushing the insertion rod 602, the socket tube 601 and the protrusion 603 and the annular pressure plate 604 and the insertion rod 602 are all clearance fit, so that the air pressure inside and outside the limiting member 6 is consistent.

[0041] As a supplement to this solution, the placement plate 5 is pulled out of the detection chamber, and the automotive lamp to be tested is placed in the placement slot 501. After the box door 101 is closed, each detection chamber is in a closed state. The controller controls the air pump 203 to turn on, and outside air is pumped into the detection chamber. When the air pressure in one of the detection chambers reaches the set value, the controller controls the first solenoid valve 202 on the corresponding side to close, until the air pressure in all detection chambers reaches the set value. The air pressure in the detection chamber is detected by the pressure sensor 3. At the same time, the rotating shaft 701 is rotated, and the rotation of the cam 702 drives the push rod 704 to move up and down along the inner wall of the vertical tube 703, thereby pushing the bottom of the automotive lamp and causing the automotive lamp to flip and shift, preventing the placement slot 501 from contacting the bottom of the automotive lamp and blocking the leakage point of the automotive lamp. If the pressure drop in the detection chamber exceeds the threshold within the set time (e.g., set to 20 seconds), it is judged as unqualified; if it does not exceed the threshold, it is qualified.

[0042] After the test is completed, the second solenoid valve 206 is opened, and the high-pressure air in the test chamber is discharged through the exhaust pipe 205.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
