Test detecting device with safety belt height adjuster and detecting method for test detecting device

Abstract

The invention discloses a test detecting device with a safety belt height adjuster and a detecting method for the test detecting device. The detecting device comprises a detecting sample, a driving unit and a detecting unit, wherein the detecting sample comprises a sample installing plate for installing the detecting sample and a cylinder for pressing and unlocking the detecting sample; the driving unit and the detecting unit are arranged on the sample installing plate; the driving unit comprises a driving motor, a ball screw and a screw nut in match with the ball screw; a force sensor bracket is connected with the screw nut; the detecting unit comprises a force sensor and a displacement sensor; the cylinder is installed on a cylinder installing plate; when the detecting sample is locked, a piston rod of the cylinder is mutually contacted with a locking button of the detecting sample; one end of the force sensor is connected with the force sensor bracket; the other end of the force sensor is connected with one end of the cylinder installing plate; and the other end of the cylinder installing plate is mutually connected with a detecting head of the displacement sensor. With adoption of the test detecting device, a force and a moving distance can be fed back precisely, and objective data, such as operation comfort can be further displayed.

Description

technical field [0001] The invention relates to the technical field of auto parts detection, in particular to a test detection device and a detection method for a safety belt height adjuster. Background technique [0002] With the continuous improvement of users' requirements for car ride comfort and safety, as an auxiliary device for seat belt adjustment, the frequency of use of height adjusters increases accordingly. At present, the height adjuster is generally installed on the B-pillar of the car (especially the car). Drivers of different heights or shapes can adjust the contact position between the seat belt and the driver's body according to their own comfort requirements; by adjusting the height adjuster The position changes to adjust the contact position and the size of the contact force to meet the requirements of the best safety and ride comfort. In view of this, the enterprise will take the durability test of different height adjusters of the corresponding model a...

Problems solved by technology

[0003] Since the early seat belt height adjuster test device did not strictly formulate the test standard, the detection range was small, and most of them were not included in the scope of investigation. At the same time, the installation and clamping of the test product were cumbersome, and the test process could not be well controlled and adjusted. During the test process, the objective data such as the user’s strength, moving distance and operating comfort cannot be accurately fed back, so it is difficult to analyze and adjust the design in the later stage, and it is difficult to meet the test requirements of parts
