Embodiment Construction

[0014] Below in conjunction with accompanying drawing, further describe the present invention in detail:

[0015] see figure 1 and image 3 , the airbag cover rigidity testing equipment is composed of a force loader 1, a laser range finder 5, a sample clamping tool 4, a computer 7 and a finger simulation tool 2. The force loader 1, the laser range finder 5, the sample clamping tool 4, and the computer 7 are existing equipment. The force loader 1 has an output range of 0-100N, and can continuously record the force output curve. One end of the telescopic rod 1.1 of the force loader 1 has an external thread. The laser range finder 5 can accurately measure the subtle deformation of the cover plate, and can continuously record the displacement change.

[0016] see figure 2 and image 3 , The simulated finger tooling 2 is composed of the fingertip part 2.1 of the simulated finger and an internally threaded joint 2.2, the internally threaded joint 2.2 is matched with the extern...

Abstract

The invention provides rigidity test equipment of an airbag cover plate. The rigidity test equipment comprises a force loader, a laser range finder, a sample piece clamping tool, a computer and a finger simulation tool, wherein the finger simulation tool is installed on the loading end of the force loader and is used for simulating a finger to press an airbag cover, the computer is used for receiving a force value output by the force loader and displacement deformation output by the laser range finder, and the sample piece clamping tool is used for fixing the airbag cover plate. A test method comprises the steps of installing the finger simulation tool on the force loader, selecting an area, which is frequently pressed, from a sample piece of the cover plate, applying load to the selected area by the finger tool, recording the displacement deformation of the cover plate by the laser range finder, and outputting a force-displacement curve graph by the computer according to force and displacement which are output by the force loader and the laser range finder. According to the test equipment and the test method, the deformation of the cover plate under stress can be conveniently tested, and the rigidity of the cover plate is quantitatively described.

Description

technical field [0001] The invention belongs to the testing technology of automobiles, and in particular relates to a testing device and method for an airbag cover plate. Background technique [0002] The driver's airbag is assembled inside the steering wheel, and is installed and protected by the driver's airbag cover. The driver's airbag cover must not only meet the airbag detonation performance requirements, but also meet the requirements of sufficient rigidity when pressing the horn. At present, the stiffness of the cover plate is mainly evaluated through subjective pressing, and there is no quantitative test detection and data description. Contents of the invention [0003] The invention provides an automobile safety airbag cover plate rigidity testing device and a method for implementing stiffness detection by using the device, which can conveniently test the deformation amount of the cover plate under a force condition, and quantitatively describe the cover plate st...
