Description

Technical Field

[0001] The invention relates to the field of working condition simulation testing, and in particular to a performance testing platform for a lighting module. Background Art

[0002] The preliminary test of the performance of the lighting module is usually completed in the laboratory. The environment in the laboratory is often an ideal environment, which is often quite different from the actual working environment of the product. Therefore, even if the lighting module shows stable performance in the laboratory, it cannot guarantee that the product put into actual use can always maintain stable performance, especially under some extreme working conditions.

[0003] For example, the lighting modules installed on some engineering equipment or vehicles are often accompanied by strong vibrations during operation, and the open-air working environment means that the product is likely to be exposed to rain or even soaked in water. These adverse conditions can easily affect the stability of product performance, so it is necessary to design a test platform that simulates extreme working conditions to test the performance of the lighting module.

[0004] In addition, the test platform that simulates real working conditions can easily have an adverse effect on other precision equipment in the laboratory. For example, water set up to simulate rain and soaking in water can easily splash out in a vibrating environment, especially when the test platform is opened to put in and take out the lighting module. Even if the leaked water does not splash onto other equipment, it will make the laboratory humid, which is something the experimenters do not want to see. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a performance testing platform for a lighting module to solve the technical problems in the prior art of lacking a testing platform suitable for use in a laboratory to simulate extreme working conditions and how to minimize its impact on the laboratory environment.

[0006] Based on the above purpose, the present invention provides a performance test platform for a lighting module, comprising a base and a test box installed on the base, wherein the test box is provided with a middle test cavity and water storage cavities on both sides, and the test cavity and the water storage cavity are separated by side partitions;

[0015] Furthermore, a water leakage gap is also arranged on the inner plate of the side partition, and the water leakage gap is located above the transverse partition, and a part of the water leakage gap is covered by the outer plate of the side partition.

[0016] Furthermore, a sealing door is provided at the front of the test box body for sealing the test cavity after closing, and the sealing door is fixedly connected to the front end of the support plate.

[0017] Furthermore, the front ends of the side partitions and the transverse partitions are provided with positioning holes, and the corresponding positions of the sealing door are provided with positioning columns that match the positioning holes.

[0018] Furthermore, an electromagnet is provided in the positioning hole, and a metal sheet is fixedly connected to the outer end of the positioning column.

[0019] Furthermore, a piston plate is provided in the water storage chamber and is slidably connected to the inner wall of the test box. The clean water in the water storage chamber is located on the inner side of the piston plate. The water storage chamber outside the piston plate is a hollow cavity. The piston plate is also fixedly connected to the outer plate of the side partition.

DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0035] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0036] A first aspect of the present invention, as Figure 1 , Figure 2 and Figure 3 As shown, the performance test platform of the lighting module of the present invention comprises a base 12 and a test box 11 installed on the base 12. The main part is the test box 11. The test box 11 is provided with a central test cavity 101 and water storage cavities 102 on both sides. The central test cavity 101 is separated from the water storage cavity 102 by a side partition 17.

[0037] The test chamber 101 includes a vibration motor 19 and a spray mechanism, which are used to simulate real working conditions. The vibration motor 19 is fixedly installed at the bottom of the test box 11. After the vibration motor 19 is started, it will cause the entire test box 11 to vibrate, simulating the vibration environment of the light module. The spray mechanism includes a spray head 28 fixedly installed on the top of the test box 11 and a water pump 26 installed in the water storage chamber 102 for pumping water. The spray head 28 is connected to the water pump 26 through a water pipe 27, and the water storage chamber 102 is also provided with sufficient clean water.

[0038] In addition, if Figure 3 and Figure 4 As shown, a transverse partition 18 is arranged above the vibration motor 19, and a support plate 15 is arranged above the transverse partition 18. A light module connection seat 16 for mounting and connecting the light module is fixedly arranged at the center of the support plate 15. The support plate 15 is provided with a plurality of through holes 103. Through holes 103 are also arranged at the four corners of the light module connection seat 16 for drainage. The light module connection seat 16 is connected to the test equipment through a connecting cable 20; the test equipment is used to test whether the performance of the light module under simulated working conditions is qualified and whether it is stable.

[0039] The front end of the support plate 15 is also fixedly connected to the sealing door 13, which is used to seal the test chamber 101 after closing. In addition, after closing, the sealing door 13 is tightly attached to the diaphragm 18, so that the test chamber 101 is divided into two layers, the upper and lower layers, separated and sealed from each other by the diaphragm 18. The test chamber 101 and the water storage chamber 102 remain sealed from the outside, and the test chamber 101 and the water storage chamber 102 are connected. It should be noted that only the upper test chamber 101 above the diaphragm 18 is connected to the water storage chamber 102, and the lower test chamber 101 below the diaphragm 18 is completely sealed.

[0040] The upper test chamber 101 above the transverse partition 18 is connected to the water storage chamber 102 through two paths. A leaking seam 107 is also provided on the side partition 17. The leaking seam 107 connects the test chamber 101 and the water storage chamber 102. The leaking seam 107 is located below the support plate 15 and above the transverse partition 18, and is attached to the upper edge of the transverse partition 18. In addition, other connecting channels are required to be provided between the test chamber 101 and the water storage chamber 102. A gap can be left at the position where the top of the side partition 17 is slidably connected to the test box 11, or a small hole can be opened above the side partition 17 to connect the test chamber 101 and the water storage chamber 102.

[0041] The specific testing process is: first, install the light module on the light module connection seat 16 before testing, and then close the sealing door 13. After closing the sealing door 13, it fits tightly with the diaphragm 18 and the side diaphragm 17 to seal the test chamber 101. Then start the vibration motor 19 and the water pump 26. The vibration motor 19 causes the entire test box 11 to vibrate, simulating the vibration conditions of the operating equipment in reality. The water pump 26 draws water from the water storage chamber 102 and then sprays it toward the light module through the sprinkler head 28, simulating a rainfall scene. The rainwater flows down through the through holes 103 on the support plate 15 and the through holes 103 at the four corners of the light module connection seat 16, and flows to the top of the diaphragm 18. Since a leaking seam 107 is provided above the diaphragm 18, the rainwater can flow back to the water storage chamber 102 through the leaking seam 107.

[0042] Preferably, the water spraying rate of the sprinkler head 28 and the water drainage rate of the leaking seam 107 can be set so that the spraying rate is greater than the water drainage rate of the leaking seam 107, so that water will gradually accumulate until the lighting module is immersed in water, simulating the extreme working condition of being immersed in water.

[0043] On the other hand, after the test is completed, in order to avoid water splashing out and affecting the laboratory environment when the test platform is opened, the vibration motor 19 and the water pump 26 can be turned off first, and then wait for a while to allow the accumulated water to drain through the leaking seam 107, and then open the sealed door 13. However, waiting wastes the time of the experimenters, and some experimenters can't wait to open it in advance, resulting in water leakage and affecting the laboratory environment. Even if it is not opened in advance, some water is likely to remain on the diaphragm 18, and splash out when the sealed door 13 is opened. In addition, sometimes unexpected situations occur, and it is necessary to stop the test urgently and open the sealed door 13, then the water will leak into the laboratory before it can be drained.

[0044] Therefore, the present invention designs a drainage insurance mechanism, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the transverse partition 18 and the side partition 17 are composed of an inner plate 105 fixedly connected to the inner wall of the test box 11 and an outer plate 104 sleeved outside the inner plate 105 and slidably connected thereto, and a reset spring 110 is also connected between the inner plate 105 and the outer plate 104; the support plate 15 is slidably connected to the side partition 17 through a slide rail fixedly connected to the outer plate 104 of the side partition 17, and the leaking seam 107 is arranged on the inner plate 105 of the side partition 17, and a part of the leaking seam 107 is covered by the outer plate 104 of the side partition 17. The front ends of the outer plates 104 of the side partition 17 and the transverse partition 18 are provided with positioning holes 108, and the corresponding positions of the sealing door 13 are provided with positioning columns 111 that match the positioning holes 108. An electromagnet 109 is arranged in the positioning hole 108, and a metal sheet 112 is fixedly connected to the outer end of the positioning column 111.

[0045] In addition, a piston plate 106 is provided in the water storage chamber 102 and is slidably connected to the inner wall of the test box 11. The clean water in the water storage chamber 102 is located inside the piston plate 106. The water storage chamber 102 outside the piston plate 106 is a hollow cavity. The piston plate 106 is also fixedly connected to the outer plate 104 of the side partition 17. The part that is connected to the leaking seam 107 is the water storage chamber 102 part inside the piston plate 106.

[0046] Therefore, when the sealing door 13 is opened, the sealing door 13 will move the outer plates 104 of the side partitions 17 and the transverse partitions 18. The outer plate 104 of the transverse partition 18 moves to prevent moisture from flowing into the lower test cavity 101 below the transverse partition 18, and the movement of the outer plate 104 of the side partition 17 has two functions. One is to expose the leaking seam 107 covered by the outer plate 104 again, thereby increasing the area of ​​the leaking seam 107 and increasing the drainage rate, so that the water can be drained quickly. Another function is that the movement of the outer plate 104 moves the piston plate 106, and the movement of the piston plate 106 rapidly increases the space of the water storage chamber 102 inside the piston plate 106. Since the small hole set above the side partition plate 17 to connect the test chamber 101 and the water storage chamber 102 has a small aperture and a limited air flow rate, a large negative pressure is generated in the water storage chamber 102 inside the piston plate 106, and then suction is generated at the leaking seam 107, so that the residual water is quickly sucked into the water storage chamber 102 through the leaking seam 107, ensuring that no water will splash out when the sealing door 13 is opened under any circumstances.

[0047] Among them, the electromagnet 109 can be set to control by setting a switch. After opening the sealing door 13, the experimenter observes whether the water is drained, and then closes the switch of the electromagnet 109, so that the sealing door 13 is separated from the outer plate 104 of the side partition 17 and the transverse partition 18, and then the outer plate 104 of the side partition 17 and the transverse partition 18 shrinks and resets under the action of the reset spring 110. The suction force of the electromagnet 109 can also be set in advance. As the sealing door 13 is opened more and more, the pulling force of the reset spring 110 becomes larger and larger, and finally exceeds the suction force of the electromagnet 109, then the sealing door 13 is automatically separated from the outer plate 104 of the side partition 17 and the transverse partition 18, and then the outer plate 104 of the side partition 17 and the transverse partition 18 shrinks and resets under the action of the reset spring 110.

[0048] On the other hand, Figure 2 and Figure 3 As shown, a cable 22 is also connected to the rear side of the light module connection seat 16, and the other end of the cable 22 is fixedly connected to a slider 23, and the slider 23 is slidably connected to a slide bar 24, and the slide bar 24 is fixedly connected to the outer plate 104 of the side partition 17 through mounting seats at both ends, and a tension spring 25 is also sleeved on the slide bar 24, and one end of the tension spring 25 is connected to the slider 23, and the other end is connected to the mounting seat at the inner end of the slide bar 24. The lower end of the slider 23 is rotatably connected to a steering wheel 21, and the connecting cable 20 is connected to the steering wheel 21.

[0049] The tension spring 25 and the return spring 110 can not only ensure the stability of the entire system and the sealing after the sealing door 13 is closed, but also the connecting cable 20 is connected to the bottom of the slider 23 through the steering wheel 21, so that the connecting cable 20 always moves with the cable 22, ensuring that the connecting cable 20 is always in a limited space, preventing the connecting cable 20 from being entangled or stuck.

[0050] On the other hand, Figure 7 As shown, a stabilizing leg 14 is also provided at the lower end of the base 12, and a protrusion 113 is provided at the connection between the base 12 and the stabilizing leg 14. The portion where the upper end of the stabilizing leg 14 is connected to the base 12 is a cylindrical member, and the protrusion 113 is located inside the cylindrical member. A buffer spring 114 is connected between the protrusion 113 and the bottom of the cylindrical member, and a buffer pad 115 is also filled in the gap between the protrusion 113 and the side wall of the cylindrical member.

[0051] Therefore, when the vibration motor 19 causes the entire test box 11 to vibrate, the test box 11 will deviate and shake relative to the base 12, while the base 12 itself can remain stable. When shaking, due to the effects of the buffer spring 114 and the buffer pad 115, the test box 11 will not collide hard with the base 12. Specific embodiments

[0052] When testing the performance of the lighting module under simulated actual working conditions, first open the sealing door 13, then install the lighting module on the lighting module connector 16, perform preliminary debugging on the testing equipment to ensure that there is no problem with the connection of the lighting module, then close the sealing door 13, and ensure that the sealing door 13 is closed and the test chamber 101 is sealed (this can be judged by pulling the sealing door 13, after the metal sheet 112 at the outer end of the positioning column 111 is attracted by the electromagnet 109 in the positioning hole 108, the sealing door 13 will not be easy to pull open, which means that the sealing door 13 is closed).

[0053] After the above preparations are completed, start the vibration motor 19 and the water pump 26. The vibration motor 19 causes the entire test box 11 to vibrate, simulating the vibration conditions of the operating equipment in reality. The water pump 26 draws water from the water storage chamber 102 and then sprays it toward the light module through the sprinkler head 28, simulating a rainfall scene. The rainwater flows down through the through holes 103 on the support plate 15 and the through holes 103 at the four corners of the light module connection seat 16, and flows to the top of the diaphragm 18. Since a leaky seam 107 is provided above the diaphragm 18, the rainwater can flow back to the water storage chamber 102 through the leaky seam 107. In addition, the water spraying rate of the sprinkler head 28 and the drainage rate of the leaky seam 107 are set so that the spraying rate is greater than the drainage rate of the leaky seam 107. Therefore, water will gradually accumulate until the light module is soaked in water, simulating the extreme condition of soaking in water.

[0054] The testing equipment is used to test the performance and stability of the lighting module under the above three working conditions and under the conditions of vibration and water immersion at the same time.

[0055] Finally, after the test is completed, in order to avoid water splashing out and affecting the laboratory environment when the test platform is opened, the vibration motor 19 and the water pump 26 are first turned off, and a period of time can be waited for the accumulated water to be drained through the leaking seam 107, and then the sealing door 13 is opened, or the sealing door 13 can be directly opened.

[0056] When the sealing door 13 is opened, the metal sheet 112 at the outer end of the positioning column 111 on the sealing door 13 is attracted by the electromagnet 109 in the positioning hole 108 on the outer plate 104 of the side partition 17 and the transverse partition 18, so the sealing door 13 will move with the outer plate 104 of the side partition 17 and the transverse partition 18. The outer plate 104 of the transverse partition 18 moves to prevent water from flowing into the lower test cavity 101 below the transverse partition 18. The movement of the outer plate 104 of the side partition 17 exposes the leaking seam 107 covered by the outer plate 104 again, increases the area of ​​the leaking seam 107, and then increases the drainage rate, so that the water is drained quickly. In addition, the movement of the outer plate 104 brings with it the movement of the piston plate 106, and the movement of the piston plate 106 rapidly increases the space of the water storage chamber 102 inside the piston plate 106. Since the small hole set above the side partition plate 17 to connect the test chamber 101 and the water storage chamber 102 has a small aperture and a limited air flow rate, a large negative pressure is generated in the water storage chamber 102 inside the piston plate 106, and then suction is generated at the leaking gap 107, so that the residual water is quickly sucked into the water storage chamber 102 through the leaking gap 107, ensuring that when the sealing door 13 is opened under any circumstances, the water is sucked into the water storage chamber 102 through the leaking gap 107 in a short time, and will not splash out to affect laboratory equipment or environment.

[0057] As the sealing door 13 opens more and more, the pulling force of the reset spring 110 becomes greater and greater, and finally becomes greater than the suction force of the electromagnet 109, the sealing door 13 automatically separates from the outer plate 104 of the side partition 17 and the transverse partition 18, and then the outer plate 104 of the side partition 17 and the transverse partition 18 shrinks and resets under the action of the reset spring 110.

[0058] Finally, take out the light module and wipe off the remaining water stains on the light module with a dry towel or paper.

[0059] Based on the above, the present invention designs a test platform that simulates extreme working conditions in reality. A vibration motor 19 and a spray mechanism are set in the test chamber 101, and the spraying rate is greater than the drainage rate of the leaking seam 107, so water will gradually accumulate until the product is soaked in water, which is very consistent with the product working conditions in an open-air working environment. After the sealing door 13 is closed, the test chamber 101 and the water storage chamber 102 in the test box 11 are both in a sealed environment, and the entire test process is also carried out in the sealed chamber, and water will not splash out and affect the laboratory environment. When the sealing door 13 is opened, it will move with the outer plate 104 and the piston plate 106, so that the leaking seam 107 becomes larger, and the air pressure in the water storage chamber 102 becomes lower, so that a large pressure difference is generated in the water storage chamber 102 and the test chamber 101, and then suction is generated in the leaking seam 107 to suck away the residual water, so as to avoid the residual water from leaking out and affecting the laboratory environment after the sealing door 13 is opened.
