Description

technical field [0001] The invention relates to the technical field of assembly of auto parts, in particular to a fastening structure for compensating tolerances. Background technique [0002] With the rapid development of the automobile industry, the assembly requirements for automobile hidden door handles, headlights and other parts that need to adjust the clearance and surface difference during the assembly process are also getting higher and higher. In order to ensure the appearance of the sheet metal, such as the current The installation sheet metal of the hidden door handle of the car is fixed with the outer sheet metal by glue. However, during the assembly process, the gap and surface difference between the accessories need to be adjusted. This assembly method is not easy to control and will make the accessories The assembly size error between them is relatively large. Contents of the invention [0003] In view of the above problems, the present invention provides ...
