[0007] By adopting the technical scheme, when detecting, the light emitter emits incident light, which is reflected by the mirror of the cosmetic mirror lamp and then falls on the frosted glass light transmission screen to form a light spot. If the light spot stably falls in the light calibration mark area within a specified time, it indicates that the stability of the mirror of the cosmetic mirror lamp in the hovering position is qualified. If the light spot on the frosted glass light transmission screen moves significantly within the specified time, it indicates that the stability of the mirror of the cosmetic mirror lamp in the hovering position is unqualified. The position change of the light spot can sensitively reflect the slight displacement of the mirror of the cosmetic mirror lamp. The test method is simple, the detection precision is high, and the repeatability is high.

[0011] By adopting the technical scheme, the plurality of reflective mirrors distributed along the horizontal direction can make the hovering angle covered by the detection more comprehensive, and increase the reliability of the test.

[0012] Optionally, the frame body adopts a sealed test box.

[0013] By adopting the technical scheme, the sealed test box can effectively reduce the interference of the outside world, provide a relatively stable environment for the test, and thus improve the accuracy and reliability of the test result.

[0014] Optionally, the light emitter adopts a single-beam light emitter.

[0015] By adopting the technical scheme, the single-beam light emitter can provide high-precision and high-reliability detection effect, and has a simple structure, a small size, and effectively reduces the cost.

[0016] Optionally, the light spot imaged on the frosted glass light transmission screen can be captured by a CCD camera.

[0017] By adopting the technical scheme, the CCD camera has a fast reading speed, can quickly capture the position change of the light spot, reduces the misjudgment caused by the light spot moving too fast, and improves the accuracy of the detection result.

[0018] Optionally, the light calibration mark area on the frosted glass light transmission screen is provided with a plurality of.

[0019] By adopting the above technical scheme, a plurality of light calibration mark areas are arranged on the same frosted glass light transmission screen, so that the test of a plurality of hovering positions can be completed in one experiment, and the detection efficiency is improved.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. During detection, the light emitted by the light emitter is reflected by the mirror surface of the cosmetic mirror lamp and falls on the frosted glass light transmission screen to form a light spot. If the light spot falls within the light calibration mark area and the position does not change within a specified time, it indicates that the stability of the mirror surface of the cosmetic mirror lamp at the hovering position is qualified. If the light spot falling on the frosted glass light transmission screen has a significant movement within a specified time, it indicates that the stability of the mirror surface of the cosmetic mirror lamp at the hovering position is unqualified. The position change of the light spot sensitively reflects the small displacement of the mirror surface of the cosmetic mirror lamp, and the test method is simple, the detection precision is high, and the repeatability is high, so that the stability of the mirror surface of the cosmetic mirror lamp can be effectively judged.

[0022] 2. By arranging the reflecting mirror, the light that cannot be directly reflected by the mirror surface of the cosmetic mirror lamp to form a light spot on the frosted glass light transmission screen is further reflected, so as to ensure comprehensive coverage of the hovering angle detection;

[0023] 3. By adopting the sealed test box body, the interference of the outside world is effectively reduced, a relatively stable environment is provided for the test, and the accuracy and reliability of the test result are improved. BRIEF DESCRIPTION OF DRAWINGS

[0031] When the included angle between the mirror of the cosmetic mirror lamp and the horizontal direction is large, the light emitted by the light emitter 3 cannot be directly reflected by the mirror of the cosmetic mirror lamp to form a light spot on the frosted glass light transmission screen 4, therefore, a plurality of reflecting mirrors are arranged below the cosmetic mirror lamp assembly product 2 to be detected, the plurality of reflecting mirrors are distributed along the horizontal direction, and are used for reflecting the reflected light reflected by the mirror of the cosmetic mirror lamp to the frosted glass light transmission screen 4 to form a light spot.

[0032] In this embodiment, two mirrors are provided, which are a first mirror 5 and a second mirror 6, and the second mirror 6 is installed at one end of the first mirror 5 close to the ground glass light transmission screen 4; the first mirror 5 is used to reflect the reflected light L4 when the mirror surface of the makeup mirror lamp is in the fourth hovering position A4 and reflect it onto the ground glass light transmission screen 4 to form a light spot, and the second mirror 6 is used to reflect the reflected light L3 when the mirror surface of the makeup mirror lamp is in the third hovering position A3 and reflect it onto the ground glass light transmission screen 4 to form a light spot.

[0033] The light emitter 3 adopts a single-beam light emitter 3 and is installed at one end away from the rotating shaft of the makeup mirror lamp assembly product 2; the ground glass light transmission screen 4 is located below the light emitter 3, and the ground glass light transmission screen 4 is provided with four light calibration mark areas corresponding to the hovering positions, which are respectively named as light calibration mark area S1, light calibration mark area S2, light calibration mark area S3 and light calibration mark area S4, and the center axes of the four light calibration mark areas are located on the same straight line.

[0034] The measurement principle of the mirror surface hovering stability test of the automobile interior makeup mirror lamp of the present application is as follows:

[0035] First, fix the makeup mirror lamp assembly product 2 to be tested at the installation port above the test box body 1, and the mirror surface of the makeup mirror lamp is located at one end of the makeup mirror lamp assembly product 2 close to the inner side of the test box body 1.

[0036] Release the unfolding mechanism to rotate the mirror surface of the makeup mirror lamp to the first hovering position A1 (the free unfolding position); the single-beam incident light L0 is emitted by the light emitter 3 to the mirror surface of the makeup mirror lamp, and the reflected light L1 of the mirror surface of the makeup mirror lamp forms the first light spot on the ground glass light transmission screen 4; if the first light spot stably falls in the light calibration mark area S1 on the ground glass light transmission screen 4, the stability of the mirror surface of the makeup mirror lamp in the first hovering position A1 is qualified; if the first light spot moves significantly within a specified time, the stability of the mirror surface of the makeup mirror lamp in the first hovering position A1 is unqualified.

[0037] Then, adjust the mirror surface of the makeup mirror lamp to the second hovering position A2 by operating the hovering angle pushing mechanism, and the reflected light L2 of the incident light L0 reflected by the mirror surface of the makeup mirror lamp forms the second light spot on the ground glass light transmission screen 4; if the second light spot stably falls in the light calibration mark area S2 on the ground glass light transmission screen 4, the stability of the mirror surface of the makeup mirror lamp in the second hovering position A2 is qualified; if the second light spot moves significantly within a specified time, the stability of the mirror surface of the makeup mirror lamp in the second hovering position A2 is unqualified.

[0038] Then, the hovering angle pushing mechanism is operated to adjust the mirror surface of the vanity mirror lamp to the third hovering position A3. Since the second mirror 6 is located on the reflected light path of the reflected light L3 of the mirror surface of the vanity mirror lamp, the reflected light L3 is reflected by the mirror surface of the second mirror 6 to the frosted glass light transmission screen 4 to form a third light spot.

[0039] Finally, the hovering angle pushing mechanism is operated to adjust the mirror surface of the vanity mirror lamp to the fourth hovering position A4 (an unfolded limit position). Since the first mirror 5 is located on the reflected light path of the reflected light L4 of the mirror surface of the vanity mirror lamp, the reflected light L4 is reflected by the mirror surface of the first mirror 5 to the frosted glass light transmission screen 4 to form a fourth light spot. If the fourth light spot stably falls in the light calibration mark area S4 on the frosted glass light transmission screen 4, the stability of the mirror surface of the vanity mirror lamp at the fourth hovering position A4 is qualified. If the fourth light spot has a significant movement within a specified time, the stability of the mirror surface of the vanity mirror lamp at the fourth hovering position A4 is unqualified.

[0040] The test result can be observed by the naked eye to determine whether the mirror surface of the vanity mirror lamp is qualified in hovering stability. Alternatively, the light spot on the frosted glass light transmission screen 4 can be captured by a CCD camera, and a pattern recognition technology can be used to determine whether the mirror surface of the vanity mirror lamp is qualified in hovering stability.
