Problems solved by technology

In some cases, it is manually tested repeatedly by testers. First, it is labor-intensive. Second, the test efficiency is low and the test cycle is long. It is a very tedious work.
Under the current trend of paying more attention to safety indicators, more large enterprises even require 30,000 times of opening and locking seat belt buckle tests to ensure its safety, which will be impossible to achieve manually

Abstract

The invention discloses a safety belt buckle durability testing apparatus, comprising a buckle clamp, a latch-bolt clamp; a first power element actuating the opening-locking actions of the buckle; a second power element actuating the inserting-drawing actions of the latch-bolt and a control device controlling the work of the first power element and the second power element. The safety belt buckle durability testing apparatus is provided with a simple structure, a convenient mounting process, a simple operation process and a practical capability. Adopting the apparatus to test the durability of the safety belt buckle largely enhances the test efficiency and shortens the test cycle and also reduces the manpower used for test.

Description

technical field [0001] The invention relates to a safety belt buckle durability test device, which belongs to the technical field of automobile product testing. Background technique [0002] The seat belt buckle (also known as the buckle) is the main component of the seat belt system. Whether this part is safe and reliable is related to the personal safety of the driver. Therefore, it is clearly stipulated in Article 4.4.1.2.1 of the national standard GB14166-2003: "The buckle must be opened and locked 500 times before the dynamic test of the seat belt". That is, 500 durable performance tests are required to ensure the safety performance of the component. There is no specific test method for testing this device at this stage, and no test device is available. In some cases, it is manually tested repeatedly by testers. First, it is labor-intensive. Second, the test efficiency is low and the test cycle is long. It is a very tedious work. Under the current trend of paying mor...
