[0016] Examples, such as Figures 1 to 3 As shown, an automatic test device for automobile interior lights includes a set of dark boxes 1 for placing interior lights for testing and a host computer 2 connected to the dark boxes 1 for communication.
[0017] The dark box 1 is provided with an indoor light fixing workbench 11. During the test, the indoor light is fixed on the indoor light fixing workbench 11. The dark box 1 is provided with a camera 13 for monitoring the indoor light. The dark box 1 is also connected with a temperature control device 3 for adjusting the temperature in the dark box 1. The temperature in the dark box 1 is adjusted by the temperature control device 3. Specifically, the temperature control device 3 is a high and low temperature test box. An air inlet pipe 31 and an air return pipe 32 are provided between the high and low temperature test box and the dark box 1. Of course, the temperature of the dark box 1 can also be adjusted by other structures, such as a hot and cold fan, which will not be listed one by one here.
[0018] In order to realize the automatic pressing of the reading light switch, a telescopic pressure rod 12 for pressing the indoor light switch is also provided in the dark box 1. In order to realize the pressing of the touch button, a capacitive pen 14 is installed on the head of the telescopic pressure rod 12. In order to realize the extension and retraction of the telescopic pressure rod 12, the telescopic pressure rod 12 is connected to a telescopic reciprocating motor 15 for driving the telescopic pressure rod 12 to move back and forth. In order to facilitate the adjustment of the position of the telescopic pressure rod 12 to meet the pressing requirements of different reading lights, a longitudinal slide rail 4 is provided on the top of the dark box 1, a longitudinal slider 5 is provided on the longitudinal slide rail 4, a transverse slide rail 6 is fixedly provided on the longitudinal slider 5, a transverse slider 7 is provided on the transverse slide rail 6, and the fixed end of the telescopic reciprocating motor 15 is fixedly installed on the transverse slider 7.
[0019] In the host computer 2, the control module 21 is respectively connected to the temperature control device 3, the telescopic pressure rod 12 and the camera 13 of the dark box 1, and is used to send relevant control instructions; the visual detection module 22 is used to process the real-time image information transmitted back by the camera 13 in the dark box 1, and analyze and process the operating status data of the automobile interior lights; the test report module 23 records the test data of the visual detection module 22 in real time and generates a test report file; the data reset module 24 resets the test data after the test is completed, so as to facilitate a new round of testing.
[0020] Step 1: At the beginning of the test, the tester can set the control parameters of the dark box through the host computer, and the control module can send the corresponding control parameter instructions to the temperature control device, camera and telescopic pressure rod of the dark box. After receiving the temperature adjustment instruction, the temperature control device adjusts the temperature of the dark box to meet the required ambient temperature in the extreme environment test scenario; after receiving the operation instruction, the camera transmits the image information in the dark box to the host computer in real time; after receiving the operation instruction, the telescopic pressure rod touches the car interior light according to the operation cycle set by the tester to realize the cycle of the interior light on and off.
[0021] Step 2: Based on the real-time image information transmitted by the camera, the visual inspection module determines the current operating status of the car interior lights according to the brightness threshold set by the tester and analyzes whether it meets the standards. Based on the judgment results, the operating status of the interior lights will be displayed in real time on the upper computer system software interface for direct observation by the tester. At the same time, the analysis results will be passed to the test report module for recording.
[0022] Step 3: During the test, the tester can decide whether to terminate the test at any time according to the test needs. If the tester chooses to continue the current test, the host system will repeat step 2; if the tester chooses to terminate the current test, the host system will jump out of step 2 and the test report module will output the test report.
[0023] Step 4: After the test report is output, if the tester needs to conduct a new round of testing, he can enter step 1 to conduct the test after resetting the test data of the previous round of testing through the data reset module; otherwise, the control module sends an end command, the temperature control device, camera and telescopic pressure rod stop running, and the host computer system software is closed.
[0024] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
