Description

Technical Field

[0001] The utility model relates to the technical field of automotive optical components, and particularly relates to a test device for the reflective performance of an automotive retroreflector. Background Art

[0002] An automotive retroreflector, also known as a reflective sheet or reflective lattice, is mainly made of plastic parts injection-molded from PMMA, PC, AS, etc. It is a passive reflector that uses the pattern inside the reflector for "borrowing light and reflecting light". Generally speaking, it is a reflector and a reflective pattern. The specific principle is that a parallel light beam passes through air and a transparent plastic sheet and enters three prism surfaces for refraction and then returns the light.

[0003] During the preparation process of an automotive retroreflector, it is necessary to test its reflective performance. The existing reflective performance test devices usually need to change the reflection angles of the automotive retroreflector multiple times in order to improve the measurement results, so as to test the reflective performance of the automotive retroreflector at multiple angles. In this process, the staff needs to use adjustment tools to change the position of the installed automotive retroreflector, and to ensure the accuracy of the data, it is necessary to calibrate and compare the installation angle of the automotive retroreflector with the changed position through an angle measuring tool. The operation is relatively cumbersome, resulting in a relatively long overall time for testing the reflective performance of the automotive retroreflector. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a test device for the reflective performance of an automotive retroreflector.

The upper side of the storage box 1 is hinged with a top cover 10 through evenly distributed hinges, and a handle 11 is provided on the upper side of the top cover 10.

[0022] Among them, the fine adjustment mechanism 8 for the reflection angle includes a base 81, a first rotating shaft 82, a rotating seat 83, a flipping seat 84, an electric rotary table 86 and an angle sensor 87. The base 81 is arranged on the bottom wall of the storage box 1. The upper side of the base 81 is rotatably connected with a rotating seat 83 through the first rotating shaft 82. The inside of the rotating seat 83 is rotatably connected with a flipping seat 84 through a second rotating shaft. Electric rotary tables 86 are provided on the top wall of the base 81 and the front side of the rotating seat 83, and angle sensors 87 are provided on the upper side of the base 81 and the rear wall of the rotating seat 83. The first rotating shaft 82 and the second rotating shaft are both fixedly connected to the rotating end of the adjacent electric rotary table 86 and the detection shaft of the angle sensor 87.

[0023] Among them, the fine adjustment mechanism 8 for the reflection angle further includes a limiting component 85. The limiting component 85 includes a telescopic column 851, a spring 852 and an arc-shaped pressing seat 853. The telescopic columns 851 are evenly arranged at the upper and lower ends of the right side inside the flipping seat 84. An arc-shaped pressing seat 853 is provided between the telescopic ends of the longitudinally adjacent telescopic columns 851. Uniformly distributed springs 852 are provided between the arc-shaped pressing seat 853 and the flipping seat 84, and the springs 852 are all movably sleeved on the outer ends of the adjacent telescopic columns 851; the limiting component 85 further includes a rubber pad 854, and the rubber pads 854 are all arranged on the side of the arc-shaped pressing seat 853 close to the center of the flipping seat 84. Horizontally insert the automotive retroreflector from right to left between the two arc-shaped pressing seats 853. The arc surface of the arc-shaped pressing seat 853 is pressed, and the telescopic ends of the telescopic columns 851 and the springs 852 contract, so as to quickly install and fix the automotive retroreflector for the light reflection performance test. The rubber pads 854 avoid the relative sliding phenomenon between the arc-shaped pressing seat 853 and the automotive retroreflector by increasing the contact friction.

[0024] The working principle of the present utility model is as follows:

[0025] When performing a retroreflective performance test on an automotive retroreflector, first open the top cover 10 through the handle 11. Then, horizontally insert the automotive retroreflector from right to left between the two arc-shaped pressing seats 853. The arc surfaces of the arc-shaped pressing seats 853 are pressed, and the telescopic ends of the telescopic columns 851 and the springs 852 contract, thereby quickly installing and fixing the automotive retroreflector for the retroreflective performance test. The rubber pads 854 increase the contact friction to prevent relative sliding between the arc-shaped pressing seats 853 and the automotive retroreflector. Subsequently, the single-chip microcomputer 2 starts the tungsten halogen lamp 4. The light source emitted by the tungsten halogen lamp 4 irradiates the automotive retroreflector through the semi-transparent mirror 5 and the light-transmitting glass 6. After the irradiated light shines on the automotive retroreflector, retroreflection occurs. The retroreflected light is reflected through the light-transmitting glass 6 and the semi-transparent mirror 5 into the photodetector 7. The single-chip microcomputer 2 starts the photodetector 7. The photodetector 7 measures the retroreflective luminous intensity coefficient and transmits the result to the single-chip microcomputer 2 in the form of an electrical signal. The single-chip microcomputer 2 compares the measured luminous intensity coefficient with the standard luminous intensity coefficient to determine whether the automotive retroreflector is qualified, and transmits the result and data comparison to the display screen 9 in the form of an electrical signal for the staff to observe;

[0026] During the retroreflective performance test of the automotive retroreflector, the single-chip microcomputer 2 starts the lower electric rotating table 86 so that its rotating end drives the rotating shaft 82 to rotate. The rotating shaft 82 indirectly drives the fixed automotive retroreflector to rotate horizontally through the rotating seat 83, thereby adjusting the retroreflective incident angle of the automotive retroreflector. During this process, the single-chip microcomputer 2 starts the lower angle sensor 87. The angle sensor 87 uses a high-performance integrated magnetic-sensitive element to measure the rotation angle of the detection shaft by utilizing the non-contact characteristic of magnetic signal induction, and transmits the measurement result of the rotation angle of the rotating shaft 82 to the single-chip microcomputer 2 in the form of an electrical signal. The single-chip microcomputer 2 controls the lower electric rotating table 86 according to the measured result, so as to accurately adjust the retroreflective incident angle of the automotive retroreflector. The single-chip microcomputer 2 starts the upper electric rotating table 86 and the angle sensor 87 to perform vertical rotation adjustment on the automotive retroreflector through the same principle. By changing the reflection angle of the automotive retroreflector, multiple groups of measurement results are obtained, thereby improving the accuracy of the device for testing the retroreflective performance of the automotive retroreflector and being convenient to use.

[0027] It should be noted that in the above embodiments, the single-chip microcomputer 2 can adopt NY8A050D, the photodetector 7 can adopt PDA10A2 silicon photodetector, the electric rotating table 86 can adopt PT-GD204 high-precision electric rotating table, the angle sensor 87 can adopt HSM22M multi-turn non-contact magnetic-sensitive potentiometer, the display screen 9 can adopt DS-D4015, and the single-chip microcomputer 2 controls the tungsten halogen lamp 4, the photodetector 7, the electric rotating table 86, the angle sensor 87 and the display screen 9 to work using the commonly used methods in the prior art.

[0028] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are similarly included within the patent protection scope of the present utility model.
