Description

Technical Field

[0001] This utility model belongs to the field of lighting testing technology, specifically relating to a testing device for automotive lighting. Background Technology

[0002] Automotive lights are an important component of vehicles, affecting not only driving safety but also the driver's experience and the vehicle's appearance. At night and in adverse weather conditions, headlights provide necessary illumination and signals to ensure driving safety. When a car is in motion, especially at high speeds, a pressure difference occurs between the inside and outside of the headlight housing. If the headlight's seal is poor, external contaminants such as water vapor and dust may be drawn into the housing, affecting lighting performance and circuit safety. Therefore, automotive lights require airtightness testing before leaving the factory.

[0003] Traditional testing devices typically test each car light individually, completing one test before moving on to the next. This sequential, single-process operation results in significant time consumption during testing, as the device remains idle while waiting for the previous light to finish testing, being removed, and preparing for the next light. This lack of time utilization directly leads to low testing efficiency.

[0004] Therefore, in order to solve the above problems, it is necessary to design a testing device for automotive lighting. Utility Model Content

[0005] The purpose of this invention is to provide a testing device for automotive lighting fixtures to solve the technical problem of low testing efficiency.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0046] like Figures 1 to 4 As shown, this embodiment provides a testing device for automotive lighting fixtures, including:

[0047] The testing platform 1; the cover assembly 2, comprising: a first telescopic member 201 and a cover 202 connected to the telescopic end of the first telescopic member 201; and the moving assembly 3, comprising: two moving platforms 301 disposed on the testing platform 1 and a testing box 302 disposed on the moving platform 301; wherein the testing box 302 is adapted to hold a plurality of lamps to be tested; the two moving platforms 301 are adapted to move the testing box 302 sequentially to below the cover 202; and the first telescopic member 201. The first telescopic component 201 is adapted to move the cover 202 downward when it is extended, so as to cooperate with the detection box 302 to form a sealed space; the one-way valve 4 is embedded in the cover 202 and is adapted to supply air into the sealed space; the pressure gauge 5 is embedded in the cover 202 and is adapted to detect the air pressure change in the sealed space; wherein the first telescopic component 201 is, but is not limited to, a cylinder; wherein the one-way valve 4 is adapted to be connected to an air pump so that when the air pump is started, air is supplied to the sealed space through the one-way valve 4, and when the air pump is turned off, the one-way valve 4 maintains pressure in the sealed space.

[0048] In this embodiment, several lamps to be tested are placed in a test box 302. A moving platform 301 moves the test box 302 containing the lamps to be tested sequentially to below the cover 202. The first telescopic component 201 extends, causing the cover 202 to move downwards, forming a sealed space with the test box 302. Air is supplied to the sealed space through a one-way valve 4. After the air supply stops, the one-way valve 4 maintains pressure. A pressure gauge 5 detects the pressure change in the sealed space. Based on the pressure change, it is determined whether the airtightness of this batch of lamps is qualified. By setting up the test box 302 and the moving component 3, continuous testing of multiple lamps is achieved, greatly shortening the testing time and improving the testing efficiency. By setting up the first telescopic component 201 and the moving platform 301, the testing process is automated, improving the testing efficiency.

[0049] The testing principle is as follows: when air is supplied to a sealed space and pressure is maintained, if the airtightness of the lamp is good, the air pressure in the sealed space will remain stable; if there is air leakage in the lamp, the air pressure in the sealed space will drop. By monitoring the air pressure change in the sealed space in real time through the air pressure gauge 5, it is possible to accurately determine whether the airtightness of the lamp is qualified.

[0050] The cover assembly 2 further includes a sealing ring 203 disposed at the bottom of the cover 202; wherein the sealing ring 203 is adapted to seal the contact point between the cover 202 and the detection box 302; wherein by setting the sealing ring 203, gas leakage is effectively prevented to ensure the accuracy of the airtightness test.

[0051] The closing assembly 2 further includes a connecting plate 204 disposed on the top of the lid 202; wherein the connecting plate 204 is connected to the telescopic end of the first telescopic member 201; wherein by setting the connecting plate 204, it is ensured that the first telescopic member 201 can drive the lid 202 to cover the detection box 302 smoothly and without shaking.

[0052] The cover assembly 2 further includes: four columns 205 disposed on the detection platform 1 and a support plate 206 connected to the four columns 205; wherein the first telescopic member 201 is disposed on the support plate 206, and the telescopic end of the first telescopic member 201 penetrates through the support plate 206; wherein by setting the columns 205 and the support plate 206, the effect of providing stable support for the first telescopic member 201 is achieved.

[0053] The lid assembly 2 further includes two guide posts 207 disposed on the top of the lid 202; wherein the guide posts 207 penetrate the support plate 206 and are slidably connected to the support plate 206; wherein by the guide posts 207 penetrating the support plate 206 and being slidably connected to the support plate 206, the guide posts 207 can slide on the support plate 206 when the first telescopic member 201 moves the lid 202 up and down, providing precise guidance for the lid 202, so as to ensure that the lid 202 can move smoothly and accurately to the position that cooperates with the detection box 302.

[0054] The moving component 3 further includes: two slide rails 303 disposed on the detection platform 1, two second telescopic members 305 disposed on the detection platform 1, and two pairs of sliders 304 disposed at the bottom of the moving platform 301; wherein each slider 304 is slidably connected to the corresponding slide rail 303; the two second telescopic members 305 are respectively connected to the corresponding moving platform 301; and the second telescopic members 305 are adapted to drive the moving platform 301 to move during extension and retraction, while each slider 304 slides on the corresponding slide rail 303; wherein the second telescopic member 305 is, but is not limited to, a long cylinder.

[0055] In this embodiment, when the mobile platform 301 needs to be moved, the two second telescopic members 305 extend and retract in sequence to move the mobile platform 301 to the bottom of the box cover 202. At the same time, the mobile platform 301 slides on the slide rail 303 through each slider 304 to make the movement of the mobile platform 301 more stable and accurate.

[0056] The detection box 302 is provided with a support frame 6; the support frame 6 is suitable for placing several lamps to be tested; by setting the support frame 6, the operator can place multiple lamps to be tested at one time, thereby reducing the time spent on repeated placement and movement of lamps and improving detection efficiency.

[0057] The mobile platform 301 is provided with a placement part 3011 on its top; wherein the detection box 302 is adapted to be placed in the placement part 3011; wherein by setting the placement part 3011, the detection box 302 is positioned to ensure that the box cover 202 can accurately cover the detection box 302.
