Description

Technical Field

[0001] This utility model relates to the field of automotive light guide component manufacturing technology, and in particular to a retroreflector water permeability testing device. Background Technology

[0002] Motor vehicle lighting and light signaling devices are crucial for safe vehicle operation. Environmental testing of retroreflectors is a mandatory inspection item for vehicle certification. Among these tests, the water permeability test is one of the mandatory certification items for retroreflectors. The method involves immersing the retroreflector in water tanks at different temperatures for an extended period, then turning it upside down in the water, and finally checking for water leakage to determine whether the retroreflector's performance meets the standard requirements.

[0003] Traditional water permeability tests often use fixed immersion or manual flipping methods, which have the following problems: the sample needs to be repeatedly disassembled to switch between the front and back sides during the test, which is inefficient and prone to human error; rigid clamps can easily damage the reflector surface or destroy the sealing structure, affecting the test results.

[0004] Therefore, it is necessary to provide a device for testing the water permeability of reflectors to solve the above-mentioned technical problems. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figures 1-4 This utility model provides a retroreflector permeability testing device, comprising: a testing device body 1 and a retroreflector 11. A control host 2 is provided on the upper part of the testing device body 1. A test water tank 3 is provided on the testing device body 1. Extension plates 4 are provided on both sides of the test water tank 3. A lifting assembly 5 is provided on the extension plates 4. The retroreflector 11 is adjusted to enter the water for permeability testing. A base 6 is fixedly connected to the lifting assembly 5. A sealed installation chamber 7 is provided on the top of the base 6. A first rotating part 8 and a second rotating part 9 are provided in the sealed installation chamber 7. Multiple clamping parts 10 are fixedly connected to the second rotating part 9. The first rotating part 8, in conjunction with the second rotating part 9, changes the direction of the clamping parts 10. The retroreflector 11 corresponds to the clamping parts 10.

[0020] The reflector 11 is fixed on the clamping part 10, and the lifting assembly 5 drives the sample to be immersed in the test water pool 3. After the front test is performed, the rotating wheel 82 is rotated to drive the first bevel gear 83 and the second bevel gear 93 to flip the sample and complete the water permeability test on the reverse side. After the test, the lifting assembly 5 is reset, and the degree of water seepage is checked by external analysis and detection equipment. Finally, the results are recorded.

[0021] The lifting assembly 5 includes a lifting drive unit 51, and a lifting plate 52 is fixedly connected to the output end of the lifting drive unit 51. A group of water-permeable holes 53 is provided on the lifting plate 52 for allowing water in the detection pool 3 to pass through during the descent.

[0022] The lifting assembly 5 controls the vertical displacement of the lifting plate 52 through the lifting drive unit 51. Combined with the design of the permeable hole group 53, it can avoid the interference of drastic water level fluctuations on the test results, while maintaining the stability of the water in the test pool 3.

[0023] The first rotating part 8 includes a first rotating rod 81, which is rotatably connected to the upper part of the sealed installation chamber 7. A rotating wheel 82 is fixedly connected to the upper part of the first rotating rod 81, and a first bevel gear 83 is fixedly connected to the upper part of the first rotating rod 81.

[0024] The first rotating part 8, through the meshing transmission of the first bevel gear 83 and the second bevel gear 93, converts the rotational force of the manually or electrically driven rotating wheel 82 into the horizontal rotation of the second rotating part 9, realizing the 180° flipping function of the clamping part 10. The permeability test of the front and back sides can be completed without disassembling the sample, thus improving the testing efficiency.

[0025] The second rotating part 9 includes a second rotating rod 91 and a bearing seat 92. The second rotating rod 91 is rotatably connected to the sealed mounting chamber 7 through the bearing seat 92. A second bevel gear 93 is fixedly connected to the second rotating rod 91. The second bevel gear 93 meshes with the first bevel gear 83. Symmetrically distributed extension rods 94 are fixedly connected to the second rotating rod 91. The clamping part 10 is located at the end of the extension rod 94 and is fixedly connected to it.

[0026] The symmetrical extension rods 94 of the second rotating part 9 ensure that the clamping part 10 is subjected to uniform force during the flipping process, avoiding sample displacement or loosening due to stress concentration on one side.

[0027] The clamping part 10 includes a fixed base 101 and a fixing member 103. The fixed base 101 has a mounting hole 102. The fixing member 103 is located in the mounting hole 102. The upper and lower sides of the fixing member 103 are respectively provided with a first clamping plate 104 and a rotating seat 105. The rotating seat 105 is connected to a second clamping plate 106 by a torsion spring, thereby clamping the retroreflector 11 between the first clamping plate 104 and the second clamping plate 106.

[0028] The fixing seat 101 and mounting hole 102 of the clamping part 10 provide an adjustable mounting reference for the fixing part 103, which can be adapted to the clamping requirements of different specifications of retroreflectors 11; the elastic structure of the first clamping plate 104 and the second clamping plate 106 connected by a torsion spring can automatically adapt to the thickness change of the reflector, ensuring clamping force while avoiding excessive compression that could cause sample deformation or sealing failure.

[0029] Contact pads 107 are provided on both the first clamping plate 104 and the second clamping plate 106, and a handle 108 is provided on the second clamping plate 106.

[0030] The contact pad 107 is made of silicone or rubber, which increases friction to prevent the sample from slipping and avoids the hard clamp from scratching the reflector surface. The handle 108 is designed to facilitate quick manual opening and closing of the second clamp 106, simplifying the clamping process and reducing the intensity of operation.

[0031] The working principle of this utility model is as follows:

[0032] The reflector 11 is fixed on the clamping part 10, and the lifting assembly 5 drives the sample to be immersed in the test water pool 3. After the front test is performed, the rotating wheel 82 is rotated to drive the first bevel gear 83 and the second bevel gear 93 to flip the sample and complete the water permeability test on the reverse side. After the test, the lifting assembly 5 is reset, and the degree of water seepage is checked by external analysis and detection equipment. Finally, the results are recorded.

[0033] The lifting assembly 5 of this utility model balances water pressure through the water-permeable hole group 53 to ensure a stable testing environment; the first bevel gear 83 and the second bevel gear 93 drive the clamping part 10 to rotate 180°, realizing the front and back of each group of reflectors 11 and water permeability testing without disassembly; the first clamping plate 104 and the second clamping plate 106 and the contact pad 107 adaptively clamp, with the functions of anti-slip and anti-damage surface, taking into account efficiency, compatibility and reliability as a whole.

[0034] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
