Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment, and in particular to a quality testing equipment for automobile taillights. Background Art

[0002] Car taillights are important safety and functional parts at the rear of the vehicle, mainly used to provide warning signals and improve visibility to other drivers. The housing of car taillights is usually made of weather-resistant plastic to protect the internal components from environmental impacts.

[0003] When the car taillight shell is produced, there will be multiple triangular columns evenly distributed on its inner wall, which can help optimize the scattering and projection of light. They reflect and refract light to make the light emitted by the taillight more uniform and increase brightness, thereby enhancing the visibility of the driver behind. At the same time, the triangular columns can increase the structural strength of the internal components of the taillight, making it more durable and able to withstand external impact. The triangular columns near the middle of the car taillight shell are more easily damaged when hit, so before using the car taillight shell, it is necessary to test the strength and integrity of the triangular columns inside it.

[0004] When the existing testing device is used to test the compressive strength of triangular columns, the test personnel cannot directly observe the test results. The test results can only be seen after the automobile taillight housing is removed from the test bench. This affects the efficiency of the test during batch testing. Summary of the invention
