Description

Technical Field

[0001] The invention relates to the technical field of rain testing, in particular to a box-type rain testing box for producing ADB automobile headlamps. Background Art

[0002] Automotive lamps need to be used in natural environments. Lamps with poor waterproof performance will produce moisture inside the lamps after water enters, affecting the illumination of the light. Lamps that have been flooded also pose certain safety hazards, shortening the service life of the lamps and resulting in high operating costs. Therefore, during the research and development or production process, the lamps need to be tested for rain exposure to determine their waterproof performance.

[0003] Current ADB headlights must undergo a rain test before installation. This is because headlights are susceptible to the effects of rainfall, which can cause physical impact and chemical corrosion, impacting performance and service life. Therefore, rain testing is necessary for outdoor equipment installation. Existing rain test chambers mostly test headlights by rotating the water jet 180°, and the jet height is fixed, which underestimates the level of headlight testing.

[0016] The present invention provides a box-type rain test chamber for the production of ADB automobile headlights. It has the following beneficial effects:

[0017] 1. The ADB car headlamp production box rain test chamber, by starting the motor, makes the screw connected to it drive the connecting rod to move up and down, thereby driving the slide rail to move, so as to adjust the distance between the upper and lower sprinklers and the headlamp, thereby simulating the headlamp test by replacing the size of rain.

[0019] 3. The ADB car headlamp production box rain test chamber, through the contraction of the expansion bladder, causes the blocking plate to move downward and cuts off the flow of water inside the return pipe, so that the upper and lower sprinklers will immediately stop spraying the headlamp.

[0020] 4. The ADB car headlamp production box-type rain test box uses a slide plate to slide upward along the inner wall of the box, eventually allowing the water to flow through the expansion pipe and along the return pipe to re-enter the upper and lower bends, thereby achieving the effect of reusing the water flow. The return device plays the role of returning the water flow.

[0021] 5. The ADB car headlamp production box type rain test box will drive the lower axis of the alkali solution tank to rotate clockwise through the other end of the connecting pipe, so that the alkali solution inside the alkali solution tank will pour into the box body to achieve the purpose of testing the alkaline resistance of the headlamp material.

[0022] 6. The ADB car headlamp production box rain test chamber neutralizes acid and alkali. The acid volume in the acid tank is greater than the alkali volume in the alkali tank. Therefore, after the acid and alkali are neutralized, the water in the box will gradually become acidic, thereby achieving the purpose of testing the acid resistance of the headlamp material.

DETAILED DESCRIPTION

[0033] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0034] like Figures 1-9As shown, the present invention provides a technical solution: a box-type rain test box for ADB automobile headlamp production, comprising a box body 1, a test device 2, an emergency stop device 3, a reflux device 4 and an acid-base detection device 5, wherein the test device 2, the emergency stop device 3, the reflux device 4 and the acid-base detection device 5 are all arranged inside the box body 1, the top of the test device 2 is connected to the emergency stop device 3, the test device 2 is connected to the reflux device 4, and the reflux device 4 is connected to the acid-base detection device 5.

[0035] The test device 2 includes a support column 21, which is connected to the reflux device 4. The surface of the support column 21 is fixedly connected to a placement table 22. The top of the placement table 22 is fixedly connected to an anti-slip claw 23 and a side frame 24. The surface of the side frame 24 is sleeved with a fixed wire sleeve 25. The fixed wire sleeve 25 is sleeved on the surface of the compartment 1. The inner wall of the compartment 1 is fixedly connected to an output device 26. The surface of the output device 26 is slidably connected to a slide rail 202. The bottom of the slide rail 202 is fixedly connected to the output device 26. The upper surface of the output device 26 is fixedly connected to an upper bend pipe 27. The side of the upper bend pipe 27 is fixedly connected to an external pipe 28. An upper sprinkler 29 is installed on the side of the upper bend pipe 27 away from the external pipe 28. The lower surface of the output device 26 is fixedly connected to a lower bend pipe 20. The side of the lower bend pipe 20 is installed with a lower sprinkler 201. By rotating the lower bend pipe 20, the upper sprinkler 29 and the lower sprinkler 201 can perform a 360-degree rain simulation test on the headlamp without dead angles.

[0036] The emergency stop device 3 includes a protective sleeve 31, the side of which is fixedly connected to the inner wall of the vehicle body 1. An expansion bladder 33 is provided inside the protective sleeve 31. An extrusion rod 32 is provided on the side of the expansion bladder 33. The end of the extrusion rod 32 away from the expansion bladder 33 is connected to the protective sleeve 31. A traction rod 34 is provided on the top of the protective sleeve 31. The end of the traction rod 34 away from the protective sleeve 31 is fixedly connected to a blocking plate 35. A return pipe 36 is provided on the surface of the blocking plate 35. One end of the return pipe 36 is mounted on the surface of the upper bend pipe 27. The end of the return pipe 36 away from the upper bend pipe 27 is connected to the return device 4. The contraction of the expansion bladder 33 causes the blocking plate 35 to move downward, cutting off the flow of water in the return pipe 36. As a result, the upper sprinkler 29 and the lower sprinkler 201 immediately stop spraying the headlights.

[0037] The reflux device 4 includes a sliding plate 41, which is sleeved on the surface of the support rod 21. A curved bar 42 is fixedly connected to the side of the sliding plate 41. A folding rod 43 is fixedly connected to the end of the folding rod 43 away from the sliding plate 41. A slide plate 44 is fixedly connected to the inner wall of the car body 1 at one end of the sliding plate 41. An expansion pipe 46 is provided on the side of the sliding plate 44. The expansion pipe 46 is sleeved on the surface of the car body 1 and is connected to the reflux pipe 36. A reflux device 45 is connected to the surface of the reflux pipe 36. The slide plate 44 slides upward along the inner wall of the car body 1, and the water flows through the expansion pipe 46 along the reflux pipe and re-enters the upper bend pipe 27 and the lower bend pipe 20, thereby achieving the effect of reusing the water flow. The reflux device 45 serves to allow the water flow to reflux.

[0038] The acid-base detection equipment 5 includes an acid-base device 51, the bottom of which is connected to the compartment 1, a connecting pipe 52 is fixedly connected to the surface of the acid-base device 51, and a sleeve strip 53 is fixedly connected to the end of the connecting pipe 52 away from the acid-base device 51, and the sleeve strip 53 is connected to the slide 44.

[0039] The output device 26 includes a motor 261, with a hollow block 262 fixedly connected to the bottom of the motor 261. The output end of the motor 261 is connected to a screw 263 via a coupling. The bottom of the screw 263 is threadedly connected to a connecting bar 264. The surface of the connecting bar 264 is connected to the slide rail 202. The slide rail 202 is provided with a slider 265. The surface of the slider 265 is fixedly connected to a bottom block 266. The top of the slider 265 is connected to the upper curved tube 27, and the bottom of the bottom block 266 is connected to the lower curved tube 20. When the motor 261 is activated, the screw 263 connected to it drives the connecting bar 264 to move up and down, thereby driving the slide rail 202 to move, thereby adjusting the distance between the upper sprinkler 29 and the lower sprinkler 201 and the headlight, thereby simulating the headlight by replacing the amount of rain.

[0040] The acid-base tester 51 includes a housing 511, the bottom of which is connected to the body 1. An upper shaft 512 and a lower shaft 514 are fixedly connected to the interior of the housing 511. The surface of the upper shaft 512 is provided with an acid tank 513, and the surface of the lower shaft 514 is provided with an alkali tank 515. The surface of the alkali tank 515 is connected to the connecting pipe 52. The other end of the connecting pipe 52 drives the alkali tank 515 to rotate clockwise around the lower shaft 514, thereby pouring the alkali solution inside the alkali tank 515 into the body 1, thereby achieving the purpose of testing the alkaline resistance of the headlamp material.

[0041] By neutralizing the acid and alkali, the acid volume in the acid tank 513 is greater than the alkali volume in the alkali tank 515. Therefore, after the acid and alkali are neutralized, the water in the compartment 1 will gradually become acidic, thereby achieving the purpose of testing the acid resistance of the headlamp material.

[0042] When in use, the car's headlights are placed on the placement table 22, and then the charging head of the headlights is connected to the fixed wire sleeve 25, so that the headlights produce lighting, and the lighting direction is facing the emergency stop device 3. Then, by starting the motor 261, the screw 263 connected thereto will drive the connecting bar 264 to move up and down, thereby driving the slide rail 202 to move, so as to adjust the distance between the upper sprinkler 29 and the lower sprinkler 201 and the headlights, thereby simulating the headlights instead of the size of rain.

[0043] As the slider 265 slides on the slide rail 202, the upper curved pipe 27 and the bottom block 266 connected thereto rotate accordingly. The lower curved pipe 20 is connected to the bottom block 266, so the lower curved pipe 20 also rotates, thereby allowing the upper sprinkler 29 and the lower sprinkler 201 to perform a 360° rain simulation test on the headlamp without blind spots.

[0044] The lighting direction of the headlamp is facing the expansion bag 33, so the expansion bag 33 will expand due to the heat. At this time, the expanded expansion bag 33 will squeeze the traction rod 34 arranged on the top thereof, so the traction rod 34 will move upward, and then the blocking plate 35 arranged on the other end of the traction rod 34 will move upward, thereby increasing the flow area inside the return pipe 36; and when the headlamp suddenly fails, the expansion bag 33 will shrink, which will eventually cause the blocking plate 35 to move downward and cut off the flow of water inside the return pipe 36, so that the upper sprinkler 29 and the lower sprinkler 201 will immediately stop spraying the headlamp.

[0045] First, water is filled into the upper bend pipe 27 and the lower bend pipe 20 through the external pipe 28. At this time, the water flow inside the car body 1 will slowly rise. When the water flow rises to the bottom of the slide plate 41, the slide plate 41 will slide upward along the surface of the support column 21. The bending bar 42 is connected to the slide plate 41, and the other end of the bending bar 42 is connected to the pull-down rod 43. At the same time, the other end of the pull-down rod 43 is connected to the slide plate 44. Therefore, the slide plate 44 will slide upward along the inner wall of the car body 1, and finally the water flow will re-enter the upper bend pipe 27 and the lower bend pipe 20 along the return pipe through the expansion pipe 46, so as to achieve the effect of reusing the water flow, wherein the reflux device 45 plays the role of allowing the water flow to reflux.

[0046] As the slide plate 44 moves upward, the strips 53 fixed on both sides thereof move upward. Since the strips 53 are connected to the connecting tube 52, the connecting tube 52 also moves upward. At this time, the other end of the connecting tube 52 drives the alkali solution tank 515 to rotate clockwise about the lower shaft 514, thereby allowing the alkali solution inside the alkali solution tank 515 to pour into the body 1, thereby achieving the purpose of testing the alkaline resistance of the headlamp material.

[0047] By continuously rotating the alkaline solution tank 515 counterclockwise, when the alkaline solution in the alkaline solution tank 515 is poured into the compartment 1, the protruding portion of the alkaline solution tank 515 squeezes the protruding portion of the acid solution tank 513. At this time, the acid solution tank 513 also rotates counterclockwise, causing the acid solution in the acid solution tank 513 to be poured into the compartment 1. At first, the acid solution will neutralize with the alkaline solution, but the acid solution capacity in the acid solution tank 513 is greater than the alkaline solution in the alkaline solution tank 515. Therefore, after the acid and alkali are neutralized, the water in the compartment 1 will gradually become acidic, thereby achieving the purpose of testing the acid resistance of the headlamp material.

[0048] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
