Description

Method and device for testing opening and closing durability of oil filler cap, terminal and storage medium

Technical Field

The invention belongs to the technical field of automobiles, and particularly relates to a method and a device for testing opening and closing durability of an oil filler cover, a terminal and a storage medium.

Background

The oil filler cover is a cover for filling a fuel port on the outer surface of an automobile body and is one of key safety parts of an automobile, and the oil filler cover needs to meet the performance test requirements of certain rigidity strength, durability, damage prevention, water prevention and the like, wherein the opening and closing durability test is one of important performance tests. The opening and closing durability test of the oil filler cover needs to repeatedly open and close the oil filler cover, and a common opening/closing mode of the common oil filler cover adopts a PUSH-PUSH mechanism, namely, when the oil filler cover is opened, the rear part of an outer plate of the oil filler cover is pressed, the PUSH-PUSH mechanism jacks the oil filler cover to a certain height, and then the oil filler cover is manually opened; when the oil filler cover is closed, the oil filler cover is manually closed to the position contacting with the PUSH-PUSH mechanism, and then the rear part of the outer plate of the oil filler cover is pressed, so that the oil filler cover is closed. In the prior published documents, when the fuel filler cap is opened/closed, the operating force value for pressing the outer plate of the fuel filler cap generally has no definite requirement or only gives a fixed value, and the disadvantage is that the operating force value cannot better simulate the working condition of operating the fuel filler cap by a user according to the specific structural form of the fuel filler cap, so that the operating force value is too large or insufficient to lose the significance of performance test.
