Problems solved by technology

[0004] However, according to the statistics of the wear and tear failure cases of the sealing strip and the analysis results of the failure location of the sealing strip, a considerable number of after-sales quality cases are caused by the frequent friction between the clothes (such as cotton clothes or jeans) and the body sealing strip when the customer enters and exits the car. The current wear-resistant test items of glass friction head and metal friction head cannot fully simulate the customer's working conditions

Abstract

The invention relates to an automobile sealing strip wear resistant test device and a test method. The device includes: a fixed tooling main body, which is equipped with a vertical sealing strip support plate; a linear reciprocating motion body, which is located at a first side of the support plate and can perform reciprocating motion perpendicular to the support plate; an angle adjustment member, which is located at a second side of the support plate; a strip-type textile, which has a first end fixed to the motion body and a second end attached to a traction part for textile stretching. During a sealing strip wear resistant test, the textile is put on a to-be-tested sealing strip at a top edge of the support plate, and passes through the angle adjustment member at the second side of the support plate, and the adjustment member adjusts the inclination angle of the part between the support plate and the adjustment member to make the textile cover a wear-resistant coating on the sealing strip appropriately. The device and method provided by the invention can simulate the abrasion of clothing to the automobile sealing strip, lower the sealing strip failure risk, are suitable for evaluation of automobile sealing strip textile wear resistance, also are low in cost, and have wide application range.

Description

technical field [0001] The invention relates to the technical field of automobile design and manufacture; in particular, the invention relates to a wear-resistant test device and a test method for automobile sealing strips. Background technique [0002] The sealing strips of automobile doors, windows and luggage compartments are usually coated with wear-resistant coating or surface flocking to improve the wear resistance of the sealing strips, so that the service life of the sealing strips matches the life of the entire vehicle. The necessary wear resistance test is carried out on the sealing strip with wear-resistant surface treatment, which can monitor the wear resistance of the sealing strip, and make necessary adjustments to the production materials and processes in the early stage of part design to improve product quality and improve customer satisfaction. vehicle satisfaction. [0003] In the existing wear-resisting testing technology of the sealing strip, a glass fri...
