[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a testing device for a rain gauge light sensor, including a stand 10 and a light shield 11 covering the stand 10. The stand 10 has a turntable unit 100, a testing station 101 for placing a sample 12 to be tested, and a testing pin 102 for electrical connection with the sample 12. The turntable unit 100 includes a transparent plate 1001 and a water film plate 1002 stacked on the transparent plate 1001. A drive unit (not shown) is provided inside the stand 10 to drive the turntable unit 100 to rotate and cover or expose the testing station 101. A first light source 103 and a second light source 104 are provided on the stand 10, with the light intensity of the first light source 103 being greater than that of the second light source 104. A controller (not shown) is provided inside the stand 10, electrically connected to the drive unit, the first light source 103, and the testing pin 102. A switch button 105 electrically connected to the controller is provided on the stand 10.
[0039] Specifically, the light shield 11 is made of opaque material. One side of the light shield 11 has an opening to facilitate equipment adjustment by the operator, while the other sides are closed to isolate ambient light. During testing, the sample to be tested 12 is placed at the test station 101. After the sample to be tested 12 is electrically connected to the test pin 102, the second light source 104 is manually turned on, and the test equipment is started via the switch button 105. The first light source 103 on the equipment then illuminates, operating at high brightness. The test checks whether the sample to be tested 12 will turn off the automatic headlight illumination function under high brightness. After a period of testing, the first light source 103 is turned off, while the second light source 104 remains on, operating at low brightness. The test then checks whether the sample to be tested 12 will activate the automatic headlight illumination function under low brightness. Then, the drive unit rotates the turntable unit 100, causing it to start rotating. The transparent plate 1001 simulates dry glass, while the water film plate 1002, which is stacked on the transparent plate 1001, can simulate a wet glass surface during rain. The transparent plate 1001 is a glass panel or an acrylic panel, and the water film plate 1002 is a bubble glass panel or a water ripple glass panel, used to simulate rain (the rain light sensor is located on the inside of the windshield. The infrared scattering rain sensor emits infrared light to illuminate the glass surface and then judges the presence of rain based on the changes in the light reflected back from the surface. When the glass surface is dry, the infrared light can pass through the glass smoothly, and the light intensity received by the sensor is high; when the glass surface is wet, the glass surface is covered by rainwater, and the infrared light is scattered by the rainwater, and the light intensity received by the sensor is significantly reduced). The bubble glass panel or the water ripple glass panel can simulate the effect of rainwater scattering. At this time, the rain light sensor is tested to see if it enters the rain mode, thus completing the test.
[0040] In this way, the testing equipment can simulate different lighting and weather conditions to accurately test the performance of the rain and light sensors, ensuring that they respond accurately in changing environments and improving driving safety.
[0041] like Figure 4 As shown, in this embodiment, the height distance between the light-emitting surface of the second light source 104 and the table surface of the stand 10 is 40-50cm, thereby ensuring that the light source of the second light source 104 uniformly illuminates and covers the table surface. In addition, the second light source 104 provides a low-brightness light source to avoid the low-brightness light source being too close to the test sample 12 and interfering with the test sample 12's accurate judgment of the light environment.
[0042] like Figure 1 and Figure 2As shown, in this embodiment, the test station 101 has a groove structure, and the frame 10 is provided with a clamping pusher 106 for clamping the sample 12 to be tested together with the inner wall of the groove structure. The clamping pusher 106 includes a fixed frame 1061, a handle 1062 rotatably disposed on the fixed frame 1061, a top clamping rod 1063 slidably sleeved on the fixed frame 1061, and a transmission rod 1064 hinged between the handle 1062 and the top clamping rod 1063.
[0043] Specifically, the sample 12 to be tested is placed in the test station 101. The groove structure of the test station 101 has a certain limiting effect on the sample 12 to be tested. Then, the handle 1062 is rotated, and the transmission rod 1064 drives the clamping rod 1063 to move, so that the front end of the clamping rod 1063 abuts against the sample 12 to be tested, thereby making the clamping rod 1063 cooperate with the inner wall of the test station 101 to achieve a stable clamping of the sample 12 to be tested.
[0044] like Figure 1 and Figure 3 As shown, in this embodiment, a control station 107 for placing standard sample 13 is provided on the table surface of the stand 10. The control station 107 and the test station 101 are arranged side by side. The control station 107 is used to place standard sample 13. The stand 10 is provided with a first indicator light (not shown in the figure) corresponding to the control station 107 and a second indicator light 1011 corresponding to the test station 101. The first indicator light and the second indicator light 1011 are electrically connected to the controller.
[0045] Specifically, standard sample 13 is used to test whether the external low-brightness light source meets the requirements. After the second light source 104 is turned on, if the low-brightness light source sensed by standard sample 13 reaches the critical threshold for the rain and light sensor to turn on, it indicates that the low-brightness light source setting is reasonable. The first indicator light will light up green, and then a red indicator light will light up to prompt the start of the test equipment to illuminate the first light source 103. The operator can confirm whether the low-brightness light source meets the standard and whether to start the subsequent test by observing the status of the first indicator light.
[0046] The second indicator light 1011 corresponding to the test station 101 will light up green after the test is completed, indicating that the sample 12 under test has passed the performance test. Otherwise, it will light up red, indicating that the performance of the sample 12 under test has not met the standard and needs to be readjusted or replaced.
[0047] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the stand 10 includes a housing 108 and a cover plate 109. A hinge 1091 connected to the housing 108 is provided on one side of the cover plate 109, which can be opened to maintain the inside of the equipment and extend the service life of the equipment.
[0048] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, handles 1081 are provided on both sides of the housing 108 to facilitate the operator to move the test equipment. During the test, the test equipment needs to be moved away from strong ambient light (e.g., away from windows) to avoid the influence of outdoor ambient light on the test.
[0049] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
