[0037] Test box bottom is equipped with four legs 1, and the bottom of the leg 1 is equipped with adjustable rubber foot pad, which can adapt to different flatness of ground by rotating the foot pad, to ensure that the test box always remains stable during working. Above the leg 1 is the box 2, which is a cuboid shape. The inside of the box 2 is reasonably divided into multiple functional areas, and the dust blowing component 6 and the water spraying component 7 are installed inside the box 2. The inside of the box 2 can accommodate different models and sizes of automobile lamps for testing.

[0038] The box cover 3 is connected to the box 2 by high-strength hinges, and the opening and closing operation is smooth and stable. The box cover 3 is equipped with a ring of high-elasticity silicone sealing strip around the edge. When the box cover 3 is closed, the sealing strip can tightly fit the box 2, forming a sealed test space, effectively preventing dust and water flow from leaking outside the box 2 during testing. On one side of the box 2, an air inlet 4 is provided to ensure sufficient air inflow. The air inlet 4 is installed with a filter screen 5 to prevent larger impurities from entering the inside, affecting the rotation of the blade 675, and preventing the rectangular box 61 from being blocked.

[0039] The dust blowing component 6 and the water spraying component 7, as important components of the test box, are arranged inside the box 2. The dust blowing component 6 simulates different concentrations and impact forces of sand and dust environment to strictly test the dustproof performance of the lamp. The water spraying component 7 sprays water to the lamp in 360 degrees without dead angle, comprehensively detecting the waterproof sealing performance of the lamp.

[0040] Through the cooperative work of the dust blowing component 6 and the water spraying component 7, the test box can accurately spray dust and water flow to the lamp, and combined with the light tester 9 and other equipment, the performance of the lamp under different environmental conditions can be detected comprehensively.

[0041] As shown in Figures 2 to 4 The inside of the box 2 is provided with a first partition 21, which divides the box 2 into a first cavity 22 and a second cavity 23. The lamp to be tested is placed in the first cavity 22, the dust blowing component 6 sprays dust into the first cavity 22, and the water spraying component 7 sprays water into the first cavity 22.

The design of the inclined plate 24 not only constructs the water tank 25, but also plays a key role in the dustproof test link. After the dust and sand particles sprayed from the circular pipe 63 complete the impact test on the car lamp, they will slide down the inclined surface of the inclined plate 24 due to gravity, and finally gather at the opening 211 below the first partition plate 21, which is convenient for recycling. The inclined plate 24 is also provided with a water outlet hole 241, the water outlet hole 241 is in communication with the water tank 25, and is used for discharging the water after the test. The water outlet hole 241 is located at the lowest point of the inclined plate 24, and the water outlet hole 241 is also provided with a filter mesh to prevent dust and sand particles from being discharged with the water flow through the water outlet hole 241.

[0044] The second cavity 23 is the core area of dust and sand storage and transmission. Above the first tapered block 26 and the second tapered block 27, as a temporary storage space for dust and sand, it provides dust and sand for the continuous conveying of the spiral auger 651. At the same time, the inclined first tapered block 26 and the second tapered block 27 can make the dust and sand move around the cylinder 65 by their own weight, and be transported by the spiral auger 651.

[0045] As Figures 3 to 6As shown, the dust blowing assembly 6 comprises a rectangular box 61, a conical barrel 62, a circular tube 63, an air inlet box 64, a cylinder 65, a drive motor 66, a rotating shaft 67, a transmission shaft 68 and a drive shaft 69.

One end of the drive shaft 69 is arranged at the bottom of the third cavity 28, and the other end penetrates the first conical block 26 and is connected with the spiral auger 651. A third pulley 691 is arranged on the drive shaft 69 and is connected with the second pulley 681 below the transmission shaft 68 through a second belt 692. The top end of the rotating shaft 67 is drivingly connected with a gas blowing assembly.

[0046] The flow splitter 611 is welded to one end of the rectangular box 61 close to the first partition plate 21, which can effectively reduce the flow resistance of dust and divide the dust and sand particles into two different flow directions, so that the dust and sand particles can be sprayed from different angles to the vehicle lamp.

[0047] The cylinder 65 penetrates the bottom of the rectangular box 61 and is internally fitted with the spiral auger 651. The dust and sand particles inside the second cavity 23 are transported to the inside of the rectangular box 61 through the spiral auger 651, and the dust and sand particles are moved by the wind generated by the rotation of the blade 675.

At the same time, the heating lamp 8 can cooperate with the water spraying assembly 7 and the dust blowing assembly 6 to simulate the high temperature, high humidity and high concentration environment, so as to test the sealing effect of the vehicle lamp under different environments. In the central position of the first partition plate 21, a high-precision light test instrument 9 is embedded and installed, which can realize real-time and accurate monitoring of the light intensity of the vehicle lamp in different test stages. The light test instrument 9 is connected with the control system outside the box body 2 through a data line, and can transmit the collected light data to the computer terminal in real time, so as to facilitate the data analysis and recording of the test personnel.

[0061] The opening 211 on the first partition plate 21 is provided with an electromagnetic valve.

[0062] It should be noted that the opening 211 is provided with an electromagnetic valve to prevent the water flow in the first cavity 22 after the test from flowing directly into the second cavity 23 through the opening 211, so as to avoid the dust and sand particles in the second cavity 23 from being agglomerated, thereby affecting the flow of the dust and sand particles.

[0063] In the working process of the application: when testing the vehicle lamp, first open the box cover 3, and fix and install the vehicle lamp on the mounting disc 74, fix the vehicle lamp through the clamping jaw 741, and at the same time, power on the vehicle lamp; the vehicle lamp is powered on and illuminated, and the light directly irradiates on the light test instrument 9, and the light intensity of the vehicle lamp is detected by the light test instrument 9.

[0064] Subsequently, the driving motor 66 on the dust blowing assembly 6 is started, the driving motor 66 drives the rotation of the rotating shaft 67, the rotating shaft 67 drives the rotation of the first bevel gear 672 and the first rotating wheel 671 in the process of rotation, the power is transmitted to the second rotating wheel 681 on the transmission shaft 68 through the first belt 682, the second rotating wheel 681 above the transmission shaft 68 drives the rotation of the transmission shaft 68, the transmission shaft 68 drives the rotation of the second rotating wheel 681 below, the third rotating wheel 691 is driven to rotate through the second belt 692, and the driving shaft 69 is driven to rotate, and the power is transmitted to the spiral auger 651 in the cylinder 65, so that the spiral auger 651 in the cylinder 65 rotates, the spiral auger 651 rotates to transport the dust and sand particles in the second cavity 23 to the top of the cylinder 65, and into the rectangular box 61, and since the first tapered block 26 and the second tapered block 27 are arranged in the second cavity 23, the dust and sand particles flow to the bottom of the cylinder 65 by their own gravity, so as to ensure the transportation of the dust and sand particles by the spiral auger 651.

[0065] At the same time, since the first bevel gear 672 and the second bevel gear 673 are engaged with each other, the second bevel gear 673 will be driven to rotate, and the external air is sucked from the air inlet 4, flows to the rectangular box 61 through the air inlet box 64, and blows the dust and sand particles transported by the spiral auger 651 at the bottom of the rectangular box 61, so as to blow the dust and sand particles to move, and the dust and sand particles will pass through the baffle 622 to enter the circular hole 621 inside the conical barrel 62, and then enter the circular tube 63 through the circular hole 621, and finally the dust and sand particles are blown to the car lamp through the free end of the circular tube 63, so as to test the car lamp, and the light emitted by the car lamp is detected by the light tester 9.

[0066] It should be noted that by controlling the rotation speed of the driving motor 66, the rotation speed of the blade 675 can be controlled, so as to control the overall wind speed and change the amount of dust and sand particles blown out. When the rotation speed of the blade 675 is fast, the rotation speed of the spiral auger 651 will also increase at the same time, and more dust and sand particles will be sent out, and the dust and sand particles with larger particles will be blown out. Higher wind speed can blow more dust and sand particles, and the baffles 622 on both sides of the flow divider 611 will rotate due to the increase of the wind speed, so that the distance between the adjacent baffles 622 increases, so that more dust and sand particles enter the conical barrel 62 along with the air, and are sprayed to the car lamp through the circular tube 63, so as to test the sealing performance of the car lamp under different concentrations of dust and sand particles and under different impact forces. The dust and sand particles blown out will fall on the inclined plate 24 by gravity, and most of the dust and sand particles will flow to the opening 211 below the first partition plate 21 through the inclined plate 24. After the detection is completed, the electromagnetic valve in the opening 211 can be controlled to be opened, and most of the dust and sand particles will flow into the second cavity 23 through the opening 211, and be recycled.

[0067] After the dustproof test is completed, the electromagnetic valve in the opening 211 is closed, and then the water pump 71 on the water spraying assembly 7 will be started, and the water in the water tank 25 is pumped into the water outlet pipe 73 through the water inlet pipe 72, and then flows into the arc-shaped hole 771 in the arc-shaped block 77 through the water outlet pipe 73, and then flows into the nozzle 79 through the arc-shaped hole 771, and finally sprays to the outer surface of the car lamp through the nozzle 79, so as to test the sealing performance of the car lamp.

[0068] When the water flow is sprayed by the nozzle 79, the rotating motor 78 will be started and drive the shaft 781 to rotate, and the second teeth 783 on the shaft 781 will mesh with the first teeth 743 on the mounting disc 74, so as to drive the mounting disc 74 to rotate slowly and drive the whole car lamp to rotate. Meanwhile, the protrusion 782 on the shaft 781 will contact with the arc-shaped push block 775 during the rotation, and push the arc-shaped push block 775 to move, and the arc-shaped block 77 will be driven by the arc-shaped push block 775 to rotate from bottom to top. When the arc-shaped block 77 rotates to the top, the outer side of the arc-shaped block 77 will contact with the rectangular push block 763 on the second fixed block 76, and push the rectangular push block 763 to move into the circular groove 761, so as to compress the first spring 762 inside the circular groove 761. With the continuous rotation of the shaft 781, the arc-shaped block 77 will be limited by the rectangular push block 763 and cannot rotate, at this time, the protrusion 782 on the shaft 781 will push the arc-shaped push block 775 to move into the circular cavity 773, and compress the second spring 774 inside the circular cavity 773. When the arc-shaped push block 775 moves, the shaft 781 will drive the protrusion 782 to continue to rotate, and the arc-shaped block 77 will not be limited, and will push the rectangular push block 763 to move and push the arc-shaped block 77 to rotate reversely through the elastic potential energy of the first spring 762. Meanwhile, the arc-shaped push block 775 will return to the original position due to the elastic potential energy of the second spring 774. After the arc-shaped block 77 reversely rotates 90 degrees, it will continue to rotate downward by its own weight until it rotates 180 degrees.

[0069] When the arc-shaped block 77 rotates 180 degrees, the protrusion 782 on the shaft 781 will contact with the arc-shaped push block 775 again and push the arc-shaped push block 775 to move, so that the arc-shaped block 77 rotates up and down on the outside of the car lamp, and the mounting disc 74 also rotates with the car lamp, and the water flow on the arc-shaped block 77 can spray the car lamp at 360 degrees without dead angle, so as to detect the water tightness of the car lamp.

[0070] After the water spray assembly 7 completes the detection of the car lamp, the heating lamp 8 can be controlled to start to heat the inside of the first cavity 22 and evaporate the water molecules inside.

[0071] In the second embodiment, the water spray assembly 7 and the dust blowing assembly 6 are cooperated and operated together when testing the car lamp, the waterproof test is carried out at the same time as the dustproof test, and the sprayed water combines with the blown dust and sand to form larger particles, so as to simulate the sealing performance test of the car lamp in the environment of water flow and dust and sand. After the test is completed, the water molecules inside are evaporated by the heating lamp 8, and then the electromagnetic valve is opened to open the opening 211, so that the dry dust and sand inside enters the second cavity 23 for recycling.

[0072] Embodiment three: the difference between this embodiment and embodiment two is that when testing the vehicle lamp, the dust blowing assembly 6 and the heating lamp 8 are operated together, and the water spraying assembly 7 will not be driven, so as to simulate the sealing performance test of the vehicle lamp in the high-temperature, high-concentration dust and sand particle environment. After the test is completed, the opening hole 211 is opened by the electromagnetic valve, so that the dry dust and sand particles inside are circulated into the second cavity 23.

[0073] Embodiment four: the difference between this embodiment and embodiment three is that when testing the vehicle lamp, the water spraying assembly 7, the dust blowing assembly 6 and the heating lamp 8 will be started at the same time, and the water spraying assembly 7 will spray water mist through the nozzle 79, so as to increase the humidity of the environment inside the box body 2, so as to simulate the sealing performance test of the vehicle lamp in the high-temperature, high-humidity and high-concentration dust and sand particle environment. After the test is completed, the water molecules inside are first evaporated by the heating lamp 8, and after the evaporation is completed, the opening hole 211 is opened by the electromagnetic valve, so that the dry dust and sand particles inside are circulated into the second cavity 23.

[0074] Finally, it should be pointed out that: the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application is described in detail with reference to the embodiments, for those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some technical features can be replaced, but any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
