Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, and more particularly to a rain testing device for automotive lighting fixtures. Background Technology

[0002] Vehicle lights are an important component that provides illumination for vehicles in the dark or when visibility is poor. During the production process of vehicle lights, it is necessary to test the sealing performance and rain protection capabilities of the lights to ensure that they can maintain stable illumination and waterproofing in rainy weather.

[0003] Existing headlight rain tests involve spraying water onto the headlight housing using a nozzle. The presence of water mist inside the housing after spraying is used to determine the headlight's seal. However, in actual use, direct spraying can result in some water getting into the headlight assembly, affecting its performance. While spraying the headlight housing can protect the back of the assembly, headlight sizes and shapes vary depending on the vehicle, requiring different housing structures, which is costly. Using pressurized nozzles for spraying has limited pressure range. During vehicle operation, the impact of rainwater on the vehicle's speed varies, especially under simulated high-speed conditions. Ordinary pressurized nozzles cannot accurately reflect the results of rain testing at high speeds. Summary of the Invention

[0004] In view of the above-mentioned problems existing in the prior art, the main objective of the present invention is to provide a rain test device for automotive lamps.

[0005] The technical solution of the present invention is as follows: a rain test device for automotive lighting includes a support base, a conical support structure fixedly mounted on the support base, a capped end fixedly mounted on the top of the conical support structure, the conical support structure including a conical outer shell and a conical support platform, a spiral acceleration bend tube mounted on the conical support platform, the spiral acceleration bend tube having an inlet through the capped end, the output port of the spiral acceleration bend tube passing through the conical outer shell and connected to an output pipe, the output port of the output pipe being fixedly connected to a connecting bag, a nozzle fixedly mounted on one end of the connecting bag, a rain sealing groove fixedly connected to the outside of the output pipe, a nozzle moving mechanism fixedly mounted inside the rain sealing groove, a vehicle light connecting structure fixedly mounted on the end of the rain sealing groove away from the output pipe, a collection pipe at the bottom of the rain sealing groove, one end of the collection pipe being connected to the support base, a water inlet pipe fixedly connected to the support base, and an inlet fixedly mounted on the end of the water inlet pipe away from the support base.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example A rain test device for automotive lighting includes a support base 1, a conical support structure 2 fixedly mounted on top of the support base 1, a capped end 3 fixedly mounted on the top of the conical support structure 2, the conical support structure 2 including a conical outer shell and a conical support platform, a spiral accelerating bend tube mounted on the conical support platform, the spiral accelerating bend tube passing through the capped end 3 and having an inlet 4, the outlet of the spiral accelerating bend tube passing through the conical outer shell and connecting to an output pipe 5, a connecting bag 6 fixedly connected to the outlet of the output pipe 5, a nozzle 7 fixedly mounted on one end of the connecting bag 6, a rain sealing groove 9 fixedly connected to the outside of the output pipe 5, a nozzle moving mechanism 8 fixedly mounted inside the rain sealing groove 9, a vehicle lighting connection structure 10 fixedly mounted on the end of the rain sealing groove 9 away from the output pipe 5, a collection pipe 11 at the bottom of the rain sealing groove 9, and one end of the collection pipe 11 connected to the support base. 1. A water supply pipe 11 is fixedly connected to the support base 1. The end of the water supply pipe 11 away from the support base 1 is fixedly connected to the inlet 4. The headlight cover is connected to the headlight cover through the headlight connection structure 10, and fits tightly with the headlight cover. A booster pump and a water pipe are connected to the inlet 4. After the water is pressurized by the booster pump, it enters the spiral acceleration bend through the inlet 4. In the spiral acceleration bend, it is further accelerated by the height difference, and then delivered to the output pipe 5 and enters the nozzle 7. The water sprayed from the nozzle 7 directly hits the headlight cover for a rain test. During the test, the nozzle moving mechanism 8 changes the spray position of the nozzle 7 to ensure that the headlight cover is fully sprayed during the rain test. The water collected in the rain sealing groove 9 enters the interior of the support base 1 through the water supply pipe 11, and then enters the inlet 4 through the collection pipe 11, realizing water recycling, energy saving and environmental protection.

[0019] The support base 1 has a water storage tank inside. The collection pipe 11 is connected to the upper part of the water storage tank. The water supply pipe 11 is equipped with a submersible pump at one end inside the water storage tank. The water storage tank stores the recycled water. The submersible pump is used to pump the water out of the water storage tank and send it back to the inlet 4 to achieve recycling.

[0020] The spiral acceleration bend is a spiral bend with a diameter that gradually increases from top to bottom. The spiral bend ensures that the conveying pipeline has sufficient acceleration length. By utilizing the height difference of the spiral bend, the water flow is further accelerated, making it faster and more suitable for simulating high-speed rain impact.

[0021] The nozzle moving mechanism 8 includes a fixed base 81, with columns 82 fixedly mounted on both sides of the fixed base 81. An electric telescopic rod 83 is fixedly mounted on the opposite side of the columns 82. The control end of the electric telescopic rod 83 is located inside the columns 82, and the output end of the electric telescopic rod 83 is fixedly connected to the nozzle 7. As the output end of the electric telescopic rod 83 on one side extends, the electric telescopic rod 83 on the other side retracts accordingly, ensuring the horizontal movement of the nozzle 7. The electric telescopic rod 83 itself has a wireless transmission module for easy wireless control.

[0022] The inlet 4 is connected to an external water pipe, one end of which is connected to a booster pump for initial acceleration. A waterproof camera is installed on the rain sealing groove 9, above the connection between the output pipe 5 and the connecting cloth bag 6. The waterproof camera is used to observe the position of the water impact, which facilitates the control of the movement of the nozzle 7.

[0023] The vehicle headlight connection structure 10 includes a flexible connecting rubber layer 101. An elastic shrink band 102 is provided at one end of the flexible connecting rubber layer 101 away from the rain sealing groove 9. The elastic shrink band 102 is used to fit and shrink the vehicle headlight cover to achieve a seal.

[0024] Working principle: As shown in the figure, during use, the headlight cover is placed inside the flexible rubber layer 101, and the headlight cover is folded together using the elastic shrink band 102. Then, the inlet 4 is connected to the external water pipe and the booster pump. The booster pump is started to pressurize and accelerate the water flow into the inlet 4. The water enters the spiral acceleration bend for secondary acceleration. After acceleration, the water flows into the nozzle 7. The water sprayed from the nozzle 7 directly hits the headlight cover to conduct a rain test. During the spraying process, the position of the water impact is observed through a waterproof camera. The nozzle moving mechanism 8 is used to change the position of the water impact to ensure that all parts of the headlight cover are sprayed, thus completing the rain test at high speed.

[0025] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
