Technical Field

[0002] With the development of the automotive industry and technological advancements, vehicle safety and comfort have become important considerations for consumers when purchasing vehicles. As an important safety feature of a vehicle, the quality and performance of headlights directly affect driving safety. Therefore, manufacturers need to ensure that every headlight produced complies with relevant international and national standards, such as ISO and ECE standards for air tightness and optical performance.
[0003] Traditional headlight testing devices often rely on a fixed illumination panel and a single measurement angle when performing optical performance tests. This means that the test results only reflect the headlight's optical performance at a specific angle, but cannot fully evaluate its overall performance at multiple angles. This limitation not only leads to one-sided test data and may omit key optical performance parameters such as beam distribution and illumination uniformity, but also has difficulty meeting the personalized needs of different vehicle models and types of headlights due to its poor adaptability. Therefore, we propose an integrated headlight airtightness and optical performance testing device to address these issues. Utility Model Content

[0022] An integrated vehicle lamp air tightness and light performance detection device, such as Figure 1-Figure 5As shown, it includes a chassis 1, which is an assembly carrier of the detection device. The upper part of the chassis 1 is a detection chamber 102 for an integrated headlight, and the front side of the detection chamber 102 of the chassis 1 is an opening; it also includes: a clamping component 2, which is installed on the bottom plate of the detection chamber 102, and the clamping component 2 is used to clamp the headlight; an airtight detection component 3, which is also installed on the bottom plate of the detection chamber 102, and the airtight detection component 3 is located on one side of the clamping component 2, and the airtight component is used to detect the airtightness of the headlight on the clamping component 2, and the clamping component 2 and the airtight detection component 3 are both prior art; an electric slide rail 4, which is arranged on the top plate of the detection chamber 102; a light receiving plate 41, which is installed on the electric slide rail 4, and the light receiving plate 41 is used to receive the luminous light of the headlight beam Parameters such as degree, color and intensity are collected to facilitate the subsequent generation of light field images to understand the light performance of the headlights; the guide frame 5 is fixedly mounted on the front opening of the detection chamber 102 of the chassis 1, and the guide frame 5 is a hollow frame; the blackout cloth 9 is arranged inside the guide frame 5, and the blackout cloth 9 is used to block the detection chamber 102 in the chassis 1, thereby effectively shielding other light sources in the surrounding environment, ensuring that only light from the tested headlights is measured during the detection process, and cooperating with the electric slide rail 4 to drive the light receiving plate 41 to adjust to a suitable light receiving position, thereby improving the accuracy and reliability of the test results. A reel for winding the blackout cloth 9 is provided in the detection chamber 102, and the reel is used to quickly reel in the blackout cloth 9 in the guide frame 5, so that the user can put in the headlights to be tested.
[0023] like Figure 1 、 Figure 3 and Figure 4 As shown, the winding member includes a mounting plate 6, a motor 7 and a winding roller 8. The mounting plate 6 is fixedly connected to the inner wall of the detection chamber 102, and the motor 7 is fixedly installed at one end of the mounting plate 6. A winding roller 8 is rotatably arranged on the mounting plate 6, and the rotating shaft of the winding roller 8 is connected to the output shaft of the motor 7. One end of the blackout cloth 9 slides through the guide frame 5 and is connected to the winding roller 8. A rebound member is provided in the guide frame 5, and the other end of the blackout cloth 9 is blocked in the entire guide frame 5 by the rebound member. The motor 7 rotates and rewinds the blackout cloth 9 through the winding roller 8, so that the blackout cloth 9 is pulled back from the guide frame 5, thereby facilitating the opening of the blackout cloth on the chassis 1; the guide frame 5 is detachably mounted on the chassis 1, and the winding roller 8 and the blackout cloth 9 are snap-fitted. The guide frame 5 and the blackout cloth 9 can be conveniently disassembled and assembled, saving the maintenance cost of the detection device.
[0024] like Figure 1 and Figure 4As shown, the resilient member includes a sliding block 10, a guide rod 11 and a spring 12. The guide rods 11 are fixed to the upper and lower sides of the inner wall of the guide frame 5. The sliding block 10 is slidably arranged in the guide frame 5 through the guide rods 11. A spring 12 is arranged between the sliding block 10 and the guide frame 5. The sliding block 10 is connected to the blackout cloth 9. The blackout cloth 9 is blocked on the entire guide frame 5 under the action of the spring 12, so that a relatively stable dark detection environment is created in the detection chamber 102 of the chassis 1.
[0025] like Figure 1 and Figure 5 As shown, a bracket 13 is fixed to the outer wall of the chassis 1, and a hinge shaft 15 is rotatably provided at the end of the bracket 13. The display 14 is rotatably mounted on the bracket 13 through the hinge shaft 15. The detection data of the airtight detection component 3 and the light receiving plate 41 are transmitted to the display 14 for display. The display 14 can be rotated and adjusted, and intuitively displays the airtightness and light performance detection parameters of the car lamp.
[0026] like Figure 1 As shown, universal wheels 101 are installed at the four corners of the bottom of the chassis 1. Braking parts are provided on the universal wheels 101. The universal wheels 101 facilitate moving the entire chassis 1, thereby improving the flexibility of use of the detection device.
[0027] First, the operator places the integrated headlight to be tested into the test chamber 102 in the chassis 1 through the opening of the guide frame 5. Before placing it in, the motor 7 drives the winding roller 8 to rotate, so that the blackout cloth 9 is quickly wound on the winding roller 8, thereby opening the entrance of the guide frame 5 and placing the headlight. Once the headlight is in place, the clamping assembly 2 is started to fix the headlight to ensure that it remains stable during the test. Next, the airtightness detection assembly 3 starts working by applying a certain pressure to the inside of the headlight and monitoring any possible pressure drop. If the headlight is airtight, it should be able to maintain a stable internal pressure; if there is a leak, it will cause the pressure to gradually decrease. At the same time, the light receiving plate 41 moves to the optimal position along the electric slide rail 4, ready for light performance testing. In order to ensure that the measurement results are not affected by external light, the motor 7 is enabled to release the winding roller 8, and the winding roller 8 no longer presses on the blackout cloth. When tension is applied to the light cloth 9, the spring 12 releases its stored energy, generating a restoring force that pushes the slider 10 in the opposite direction along the guide rod 11 within the guide frame 5. The movement of the slider 10 pulls the light cloth 9 with it, allowing it to quickly unfold and cover the entire opening of the guide frame 5, creating a dark environment for light performance testing. This ensures that only light from the tested lamp is captured by the light receiving plate 41, allowing accurate assessment of parameters such as the brightness, color, and intensity of the lamp beam. Simultaneously, all test data from the lamp's airtightness and light performance testing is transmitted to the display 14. The operator can rotate the display 14 to find the most suitable viewing angle and intuitively view all necessary test information. Finally, when the lamp testing is complete, the operator can activate the motor 7 again using a command on the control panel, rewinding the light cloth 9 and allowing removal of the tested lamp. Universal wheels 101 at the bottom of the entire testing device allow the user to easily move the device to different locations, while brakes ensure stability during use.
