A Method for Obtaining Working Characteristics of Automobile Sliding Door Limit Block

Abstract

The invention discloses a vehicle slide door stop block work characteristic obtaining method characterized by comprising the following steps: adjusting a slide door X-direction hinge position so as to compress a stop block to the limit position; measuring the gap between the slide door and the front door and the gap between the slide door and the rear side wall; quantitatively adjusting the slide door X-direction hinge position, measuring and recording the gap between the slide door and the front door after each adjustment, and the gap between the slide door and the rear side wall after each adjustment; finishing quantitative adjustment of the slide door X-direction hinge position, and obtaining the curve relation between the adjusting amount and the front door and the rear side wall gap; determining an acceptable compression amount of a concave block on the vehicle body and a convex block on the slide door according to the curve relation, and obtaining a position precision target on the concave block mount surface on the vehicle body and a convex block mount surface on the slide door. The method can obtain accurate work characteristic information of the slide door stop block.

Description

technical field [0001] The invention belongs to the technical field of automobile sliding doors, in particular to a method for obtaining the working characteristics of a limit block of an automobile sliding door. Background technique [0002] Due to the special function of the sliding door, its assembly method and positioning method are quite different from ordinary car doors. Due to the large volume and weight of the sliding door, the stability of the assembly and positioning of the sliding door is particularly worthy of attention. It plays an important role in the smoothness of the car and the prevention of abnormal noise in the door operation. Due to its functional requirements, the limit block is made of EPDM artificial rubber (EPDM ELASTOMER), so the limit block has a certain degree of elasticity, and there is a certain amount of compression during service. When the amount of compression reaches the limit, the sliding door will The positioning system function fails. ...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, how to determine the working characteristic information (such as the compression amount) of the sliding door limit block usually only depends on the design theoretical value, but in the actual production process, due to the matching state (body accuracy / fitting angle / interference amount ), material property deviation, and the characteristics of the limit block will differ from the design theoretical value, which will lead to a decrease in positioning reliability and bring troubles to the body matching process
