Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, specifically to an automotive headlight brightness testing device. Background Technology

[0002] Currently, when manufacturing automotive headlights, it is necessary to test the luminous intensity of the headlights to ensure that they can correctly illuminate the required area when driving at night. At present, when testing the luminous intensity of headlights, general light detection devices are usually used. However, general headlights can only test a certain area illuminated by the headlight, not the entire area, and the device is always fixed in place during testing.

[0003] Publication No. CN217505160U discloses an automotive headlight brightness detection device, including a base with a light-shielding cover fixedly mounted on top of the base. The light-shielding cover has movable slots on both sides of its inner top. It also includes a first driving mechanism that moves along the movable slots and drives a detection mounting base. The detection mounting base, with a concave arc end, can simulate the headlight illumination intensity at different incident angles. Furthermore, a color temperature detection mechanism is added to detect LED unit failures, increasing functionality and accuracy. However, this patent still has the following problems in practical use:

[0004] Although this vehicle headlight brightness detection device uses a detection mounting base with a concave arc end, which can simulate the headlight illumination intensity at different incident angles, it cannot simulate the headlight illumination brightness at different locations during vehicle turning and straight driving. This fails to improve the accuracy of vehicle headlight brightness detection. Since there are blind spots when turning, the headlight illumination range is particularly important. It also affects the field of vision of oncoming vehicles when meeting oncoming traffic. It cannot simulate the headlight illumination brightness during vehicle meeting and turning, resulting in unrepresentative test data.

[0005] Therefore, a vehicle headlight brightness detection device is proposed to solve the problems mentioned above. Utility Model Content

By changing the relative position of the photosensitive detector and the car headlights, it is convenient to simulate vehicle meeting and thus detect the brightness of the headlights during vehicle meeting. The adjustment motor can also drive the bidirectional adjusting threaded rod to rotate, causing the two adjusting threaded sleeves to move the second electric telescopic rod and the photosensitive detector relative to each other. Simultaneously, the height of the photosensitive detector can be adjusted using the second electric telescopic rod, facilitating the detection of brightness at different positions of the car headlights.
