Abstract
Description
Technical Field
[0001] This utility model relates to the field of component testing technology, specifically a high-temperature resistance testing structure for automotive internal plastic components. Background Technology
[0002] Plastic components inside a car are an important part of the car's interior system. They not only affect the vehicle's aesthetics and comfort, but are also closely related to its safety and functionality.
[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219142547U) discloses a high-temperature resistance testing device for plastic parts. The device includes an insulation shell, a rotating plate movably connected to the bottom of the insulation shell, a vacuum suction cup fixedly connected inside the rotating plate, and a rotating gear fixedly connected below the rotating plate. One end of the rotating gear is connected to a drive assembly, which includes a rack, a drive motor, a reciprocating slide groove, and a roller. One end of the rack is fixedly connected to the reciprocating slide groove and meshes with the rotating gear. One end of the drive motor is fixedly connected to the bottom of the insulation shell and rotatably connected to the roller. The roller is slidably connected inside the reciprocating slide groove. One end of the vacuum suction cup is fixedly connected to a rotary joint, and one end of the rotary joint is fixedly connected to a vacuum pump. A sliding groove is opened on one side of the insulation shell, and a buckle is fixedly connected to one side of the sliding groove.
[0004] Although the aforementioned patent has the advantage of driving the rotating gear to rotate through the moving component, thereby rotating the plastic parts above the vacuum suction cup and making the plastic parts heat up evenly and the experimental temperature controllable, the device cannot quickly cool down the plastic parts after the test is completed. This makes it very time-consuming and laborious for the staff to remove the tested parts, and may even result in the staff being burned.
[0005] Therefore, this utility model provides a high-temperature resistance testing structure for plastic parts inside automobiles to solve the above problems. Utility Model Content

[0029] In Example 3, based on Example 1, the blowing assembly includes a blower 4 fixedly installed on the top surface of the test box 1. An air inlet pipe 5 is fixedly connected to the air outlet end of the blower 4.

[0031] In Example 5, based on Example 1, the purification component includes two slots 11 respectively opened on one side of the inner wall of the detection box 1 and the side of the second partition 10. A frame 12 is movably inserted between the two slots 11. An activated carbon filter plate 13 is fixedly installed inside the frame 12.

After that, close the chamber door 2 and turn on the heating plate 6. The heating plate 6 heats the cavity above the first partition 9, keeping the plastic parts in a high-temperature environment to complete the high-temperature resistance test. After the test, the operator can turn on the blower 4 and the cylinder 18. The blower 4 blows external airflow into the hollow disc 7 through the air inlet pipe 5, and the airflow exits from the blower pipe 8, rapidly cooling the plastic parts. The cylinder 18 moves the baffle 19, ventilating the through hole 17, allowing the hot airflow above the first partition 9 to pass through the through hole 17 and enter the cavity below the first partition 9. This hot airflow then passes through the activated carbon filter plate 13 and exits the testing chamber 1 through the exhaust pipe 14. The activated carbon filter plate 13 filters out any toxic gases mixed in with the hot airflow, preventing them from being directly released into the external environment.
