Abstract
This application provides an anti-pinch force testing device for testing the anti-pinch force of a vehicle door, comprising: a support base; a slide rail assembly supported by the support base, the slide rail assembly including a slide rail having an arc-shaped profile, the radius of which is greater than the distance between the pivot of the vehicle door and the edge of the vehicle door; a sliding plate connected to the side of the slide rail assembly opposite to the support base and capable of sliding along the slide rail; and a force gauge fixedly connected to the sliding plate. According to the technical solution of this application, automatic matching and adaptation of the force gauge test trajectory with the movement trajectory of the vehicle door edge is achieved, reducing manual adjustment operations, improving test accuracy, simplifying the test process, automating the test, and improving test efficiency.
