Description

Technical Field

[0001] The utility model relates to a heat resistance testing device for automobile interior decoration parts, in particular to a heat resistance testing device for automobile interior decoration parts, and belongs to the technical field of heat resistance testing of automobile interior decoration parts. Background Art

[0002] With the advancement of science and technology, the automobile industry is also booming. Cars have become an indispensable and particularly important tool for every household. In the automobile production process, the automobile interior parts will be subjected to heat resistance tests after processing to test the heat resistance and thermal stability of the automobile interior parts to ensure that the automobile interior parts can maintain good performance and appearance under high temperature conditions.

[0003] A heat resistance testing device for automobile interior parts is disclosed in the Chinese patent application publication specification CN219957420U. The device can facilitate heat resistance testing of automobile interior parts and realize semi-automatic operation. There is no need for manual heating of interior parts with a heating plate, which reduces manual work intensity and improves safety. At the same time, it can also improve the accuracy and convenience of testing.

[0004] However, during the implementation of the technical solution of the above patent, the automobile interior parts cannot be heated uniformly on the surface of the interior parts during the heat resistance test. The existing heat resistance testing device will fix the interior parts and gradually move them close to the heating plate to test the heat resistance of the interior parts. This fixing method will cause one side of the interior parts to face the heating plate and the other side to face away from the heating plate. Most automobile interior parts are made of heat-insulating materials, which will make the surface temperature of the interior parts uneven. When automobile interior parts are used in actual high-temperature environments, their surrounding temperature is mostly uniform. When the surface temperature of the interior parts is uneven, it will lead to inaccurate heat resistance test results. Utility Model Content
