Description

Technical Field

[0001] The invention belongs to the technical field of automobile interior decoration part detection, and relates to a buckle pulling detection device and a detection method for automobile interior decoration parts. Background Art

[0002] The current buckle pull-out test for automotive interior parts is characterized by first assembling the plastic product and the sheet metal part, and then determining the specific test position of the dynamometer based on the spatial structure of the product to perform the buckle pull-out test.

[0003] The shortcomings of the current detection method are as follows: 1. Generally, plastic products are large interior parts, such as door panels. In order to detect the buckle pull-out force of the product, the plastic interior parts and sheet metal parts need to be assembled. Since the product itself is large, the pull-out force detection preparation process is difficult and cumbersome. Sometimes it is necessary to cut off the buckle part of the door panel and put ropes on both sides of the buckle seat to connect the dynamometer; 2. Due to the uncertainty and complexity of the structural layout of the interior products and sheet metal parts, the tensile gauge cannot detect the buckle pull-out force in the ideal position and normal direction. It is necessary to determine the specific position of the tensile gauge according to the actual space of the product and the sheet metal assembly. Detection at different positions directly affects the accuracy of the results. In summary, the existing buckle pull-out detection of automotive interior parts has many shortcomings and has a large room for improvement. Therefore, it is very beneficial to invent a buckle pull-out detection device and a detection method for automotive interior parts. Summary of the invention

[0006] A preferred technical solution of the present invention is: the snap body (100) comprises a snap-on portion (110), a force transmission portion (120) and a connecting portion (130); the snap-on portion (110), the force transmission portion (120) and the connecting portion (130) are integrally connected; the snap-on portion (110) and the connecting portion (130) are respectively located at two ends of the force transmission portion (120); the snap-on portion (110) passes through the snap-on hole (410) of the sheet metal body and is snap-on with the sheet metal body (400). The snap-on portion (110) of the snap body (100) further comprises a guide slope (111) and a limiting portion (140); the limiting portion (140) is connected to the force transmission portion (120).
