Description

Technical Field

[0001] This utility model relates to the field of vehicle lamp sealing test technology, specifically a vehicle lamp sealing test device. Background Technology

[0002] Since the 20th century, global annual automobile production has increased from several thousand to tens of thousands of vehicles, then to tens of millions, reaching approximately 42.49 million vehicles by 1978. The automotive industry has become the world's largest manufacturing industry. In the 1980s, six of the world's 20 largest industrial companies were automobile manufacturers. In 1980, the world's total number of vehicles was approximately 335 million, including 265 million passenger cars and 70 million trucks and buses. The production and use of automobiles involve a wide range of applications. The sealing performance of vehicle lights is one of the standards for measuring the quality of vehicle lights. The sealing performance of automotive lights is extremely important for automobiles; if the quality of the lights is substandard, it can easily lead to traffic accidents.

[0003] The existing Chinese utility model patent with publication number CN208458939U discloses a vehicle headlight sealing test device, including a base. Symmetrically arranged support plates are bolted to both sides of the top outer wall of the base. A common crossbeam is bolted to the outer wall of the two support plates on the side away from the base. Two symmetrically arranged water-absorbing racks are bolted to one side of the outer wall of one of the support plates, and absorbent cloth is adhered to the opposite side of the outer wall of each of the two water-absorbing racks. A water tank is bolted to the top outer wall of the base, and a water pump is bolted to the top outer wall of the water tank. This utility model allows water mist to enter the vehicle headlight through gaps, effectively improving the test effect and efficiency of the vehicle headlight sealing test. It also achieves water resource recycling, reducing resource consumption in vehicle headlight testing. The absorbent cloth on the water-absorbing rack wipes away water droplets from the surface of the vehicle headlight, facilitating observation by staff to check for water ingress inside the headlight.

[0004] In the aforementioned vehicle headlight sealing test device, the design of an atomizing nozzle, mounting cover, and water suction frame successfully solves the problem of difficulty in detecting small gaps when using water immersion testing. However, without water immersion, this device is not ideal for testing vehicle headlight sealing. To ensure the sealing of the headlight, a certain pressure must be applied through water immersion testing. Furthermore, although the device uses a water suction frame to absorb water, in actual operation, it is difficult to observe whether water has actually entered the headlight or whether water vapor can form due to water temperature and the temperature difference between the external environment and the headlight interior. This presents too many conditions that are difficult to meet, making the testing process less intuitive and affecting the accuracy of the test. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of poor detection effect and inconvenience of detection in the existing technology, and to provide a vehicle headlight sealing detection device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vehicle headlight sealing performance testing device, comprising:

[0008] The testing chamber has a rotatably connected sealing door on one side. Two air vents are located on one side of the top of the testing chamber. Four first electric actuators are fixedly installed inside the testing chamber on one side. A water tank is fixedly installed on one side of each first electric actuator. A high-pressure hose is fixedly installed on one side of the water tank. A water pump is fixedly installed on one side of the high-pressure hose. An atomizing device is fixedly installed on the top of the water pump. A drying chamber is fixedly installed on the top of one side of the testing chamber. A ventilation hole is located on the top of the drying chamber. A drying lamp is fixedly installed inside the drying chamber on one side. A sealing cover is rotatably connected to one side of the drying chamber. A sliding groove is located on the right side of the interior of the drying chamber. Two electric actuators are fixedly installed on both sides of the sliding groove. A sealing plate is fixedly installed on the top of each electric actuator.

[0009] In a preferred embodiment, an electric slide groove is fixedly provided on the top of the inside of the detection box, and a support frame is slidably connected inside the electric slide groove. The support frame is a structure for support.

[0010] In a preferred embodiment, a second electric push column is fixedly installed at the top interior of the support frame, and a clamping block is fixedly installed at the bottom of the second electric push column. The clamping block is a structure for clamping.

[0011] In a preferred embodiment, a clamping plate is fixedly installed at the bottom of the inner side of the support frame, and the clamping plate is a structure used to cooperate with the clamping block for clamping.

[0012] In a preferred embodiment, the top of the testing box is fixedly provided with an air extraction slot, and an air extraction device is fixedly installed on the top of the air extraction slot. The air extraction device is a structure used for air extraction.

[0013] In a preferred embodiment, an air blowing pipe is fixedly installed on one side of the air extraction device, and a condenser is fixedly installed on one side of the air blowing pipe. The condenser is a structure used for condensation.

[0014] In a preferred embodiment, a water outlet pipe is fixedly installed on one side of the condenser, and the water outlet pipe is a structure for discharging water.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This vehicle headlight sealing test device uses the operation of the second electric push column inside the support frame to push the clamping block to clamp the headlight. The operation of the first electric push columns on both sides of the water tank pushes the water tank upward, thereby immersing the headlight into the water tank and testing the water tank's sealing performance. A water pump draws water into the atomizing device and sprays it out, thus performing two different sealing tests on the headlight. A condenser facilitates the condensation of the water vapor extracted by the suction device, and the water is returned to the water tank through the outlet pipe, improving the practicality and testing effect of the vehicle headlight sealing test device.

[0017] 2. This vehicle headlight sealing test device uses an electric sliding chute to move the clamped headlight into the drying chamber. Two electric push rods inside the chute push the sealing plate upwards, sealing the connection between the test chamber and the drying chamber. The drying lamp dries the headlight, and hot air is expelled through ventilation holes. The drying process causes the moisture inside the headlight to appear as a mist on the surface, facilitating the testing of the headlight's sealing performance and improving the effectiveness of the device.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Combined with appendix Figure 1-4 In this embodiment, a vehicle headlight sealing performance testing device includes: a testing box 1, a sealing door 11 rotatably connected to one side of the testing box 1, two air vents 12 on one side of the top of the testing box 1, four first electric push rods 13 fixedly installed inside one side of the testing box 1, a water tank 14 fixedly installed on one side of the first electric push rods 13, a high-pressure hose 15 fixedly installed on one side of the water tank 14, a water pump 16 fixedly installed on one side of the high-pressure hose 15, an atomizing device 17 fixedly installed on the top of the water pump 16, a drying box 18 fixedly installed on the top of one side of the testing box 1, a ventilation hole 19 opened on the top of the drying box 18, a drying lamp 110 fixedly installed inside one side of the drying box 18, a sealing cover 111 rotatably connected to one side of the drying box 18, a sliding groove 112 opened on the right side of the interior of the drying box 18, two electric push rods 113 fixedly installed on both sides of the interior of the sliding groove 112, and a sealing plate 114 fixedly installed on the top of the electric push rods 113.

[0025] Specifically, by flipping the sealing door 11, one side of the test box 1 is sealed; by flipping the sealing cover 111, one side of the drying box 18 is sealed; by operating the electric push rod 113 inside the sliding groove 112 on one side of the drying box 18, the sealing plate 114 is pushed upward, thereby sealing the gap between the drying box 18 and the test box 1; by operating the first electric push column 13, the water tank 14 is adjusted in height; by operating the water pump 16, the water inside the water tank 14 is drawn out through the high-pressure hose 15 and sent into the atomizing device 17 for atomization and spraying.

[0026] An electric slide 2 is fixedly provided on the top of the inside of the testing box 1. A support frame 21 is slidably connected inside the electric slide 2. A second electric push column 22 is fixedly installed on the top of the inside of the support frame 21. A clamping block 23 is fixedly installed on the bottom of the second electric push column 22. A clamping plate 24 is fixedly installed on the bottom of the inside of the support frame 21.

[0027] Specifically, the operation of the electric slide 2, i.e. the start and operation of the electric slide 2, can effectively drive the support frame 21 to slide smoothly inside it. The top second electric push column 22 inside the support frame 21 then operates, thereby pushing the clamping block 23 to move downward. The coordinated work of this series of actions enables the clamping block 23 to closely cooperate with the clamping plate 24 to accurately clamp the vehicle light. Finally, through the continuous operation of the electric slide 2, the movement operation of the vehicle light is realized, ensuring the efficiency and stability of the entire clamping and movement process.

[0028] The top of the test box 1 is fixedly provided with an air extraction slot 3, the top of the air extraction slot 3 is fixedly installed with an air extraction device 31, an air blowing pipe 32 is fixedly installed on one side of the air extraction device 31, a condenser 33 is fixedly installed on one side of the air blowing pipe 32, and a water outlet pipe 34 is fixedly installed on one side of the condenser 33.

[0029] Specifically, through the continuous operation of the suction device 31, the core function of the suction device 31 is to extract gas from the closed space through the gas pressure difference to form a negative pressure environment. Through the mechanical movement of the reciprocating piston, the volume of the pump chamber is changed periodically to form a gas compression and emission cycle. This realizes the effective extraction of atomized gas through the air outlet 12 of the suction slot 3. Subsequently, the extracted atomized gas is sent into the interior of the condenser 33 through the air blowing pipe 32 for condensation treatment. After the condensation process, the obtained pure water is sent back to the interior of the water tank 14 through the water outlet pipe 34, thus completing the entire cycle process.

[0030] Working principle: First, the headlight is placed inside the support frame 21. The movement of the second electric push column 22 inside the support frame 21 pushes the clamping block 23 downwards, coordinating with the clamping plate 24 to clamp the second headlight vertically. By rotating the sealing door 11, one side of the test box 1 is closed. The movement of the first electric push columns 13 on both sides of the water tank 14 pushes the water tank 14 upwards, immersing the headlight inside the water tank 14 for a water immersion seal test. The sealing effect is tested by immersion. After the test is completed, the second electric push column 22... The retraction of the electric push column 13 causes the water tank 14 to reset. The operation of the electric slide 2 causes the support frame 21 to slide to the left inside, moving the headlight to the top of the atomizing device 17. The operation of the water pump 16 draws water from the water tank 14 through the high-pressure hose 15 and sends it into the atomizing device 17. The atomizing device 17 then sprays the water onto the headlight, facilitating a seal test on small gaps in the headlight. The operation of the air extraction device 31 causes the air extraction channel 3 to open through the air outlet 12. After the atomized gas is drawn in, it is sent into the condenser 33 through the air blowing pipe 32, which facilitates the collection and condensation of the atomized water. Finally, the condensed water is sent back to the water tank 14 through the water outlet pipe 34 for collection and recycling, which improves the convenience of the vehicle headlight sealing test device. At the same time, by using two sealing tests, the accuracy of the vehicle headlight sealing test device is improved. After the test is completed, the electric slide 2 drives the clamped vehicle headlight into the drying chamber 18, and the electric push rod 11 in the sliding groove 112 on one side of the drying chamber 18 moves the light. The operation of step 3 pushes the sealing plate 114 upward, thereby sealing the connection between the drying chamber 18 and the testing chamber 1. The operation of the drying lamp 110 on one side of the drying chamber 18 dries the vehicle lamp. The water vapor is discharged through the ventilation hole 19 at the top of the drying chamber 18. After drying, if the sealing is insufficient and water vapor enters the vehicle lamp, water mist will form inside the vehicle lamp after drying, which is convenient for testing the sealing of the vehicle lamp. This avoids the problem of a small amount of water vapor entering and making it difficult to test, and improves the practicality of the vehicle lamp sealing test device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
