Description

Technical Field

[0001] The invention relates to the field of test lamps, in particular to a test device and a test method for automobile lamps. Background Art

[0002] As a key safety component of a vehicle, the performance of car lights is directly related to driving safety. Therefore, it is very important to conduct a comprehensive inspection of car lights. The commonly used car light inspection methods are mainly to test the functional reliability of car lights;

[0003] The existing Chinese patent with publication number CN118311476B discloses a testing device and testing method for new energy vehicle headlights, including a detection body for testing headlights and a lamp holder for placing headlights. A detection cavity is provided on the surface of the detection body, and both ends of the detection cavity are open. Conveyor belts are installed at both ends of the detection body. The conveying end surfaces of the two conveyor belts are respectively aligned with the openings at both ends of the detection cavity, and a detection mechanism is installed on the inner wall of the upper end of the detection cavity. The testing device and testing method for new energy vehicle headlights separate the lamp holder from the detection body, use multiple lamp holders to match the headlights into the detection body, and use the conveyor belt to convey the lamp holder and the headlight in an assembly line manner, thereby improving the detection efficiency, and reducing labor costs by realizing automated operations. At the same time, automatic transportation and output are realized by means of conveyor belts, which can adapt to production needs of different scales and have strong scalability.

[0004] However, the testing device and testing method for new energy vehicle lamps still have the following defects:

[0005] 1. The corners of car lights are where stress is concentrated. In actual use, the corners are the most likely locations for the front and rear lights to break, because the corners are more susceptible to scratches or impacts. These external factors increase the risk of corner breakage. When the glass is impacted by external forces, these stress-concentrated areas are more likely to break. In addition, the lights are installed in accordance with the shape of the car model, not flat, and cannot fully simulate the compressive strength of the corners after installation.

[0006] 2. In addition to testing the strength and rigidity of the headlights during use, it is also necessary to test the waterproofness and insulation of the headlights. The waterproof performance is to adapt to extreme weather such as rain and snow. Because the headlights and the body frame are spliced ​​and installed, there are gaps in the joints. Water vapor will enter the headlights through the gaps and affect the life of the headlights. The headlights are made of translucent polyethylene, and the insulation affects the ability of the headlights to absorb dust, thereby affecting the lighting ability of the headlights.

[0038] The present invention provides a testing device and a testing method for automobile lamps through improvements, which have the following improvements and advantages compared with the prior art:

[0039] Firstly, the raised shape of the edge of the pressure test plate is used to increase the pressure felt by the corners of the car headlights when pressing down, simulating the pressure on the corners after external impact. Because the corners of the headlights are at the stress concentration position, in actual use, the corners are where the most broken parts of both the front and rear headlights are. In addition, the angle of the car headlight model of the headlight support plate order is adjusted by rotating the first socket roller and the second socket roller to further simulate the pressure resistance of the headlight corners at different angles after installation. Because the headlights are installed to fit the shape of the car model and are not flat, according to the specific shape of the headlights, the impact forces at different angles will have different pressures on the corners of the car. The structure of the device can adjust the angle of the headlight body and the direction of the pressure test structure according to the shape of different cars, so as to detect the maximum strength and rigidity that the headlights can withstand during use.

[0040] Secondly, by injecting gas into the car headlight model through the gas pressure relief pipes connected on both sides of the car headlight model, the air tightness of the headlight body and the waterproofness of the headlight can be tested. The purpose of testing the air tightness is to test the adaptability of the headlight to extreme rain and snow weather. Because the headlight and the body frame are installed in a splicing manner, there are gaps in the joints. Water vapor in a high temperature environment will enter the headlight through the gaps. Too low temperature and too large temperature difference between the inside and outside will affect the life of the headlight. The pressure that the inside of the headlight can withstand can be detected by increasing the air pressure. In addition, the insulation of the headlight surface can be tested through the power transmission port. The material of the headlight body is translucent plexiglass. The purpose of testing the insulation at the power transmission port is to test the headlight's ability to resist dust adsorption. Dust adsorption is due to the static electricity easily generated on the surface of the headlight, which leads to dust adsorption and affects the lighting ability of the headlight.
