Description

Fixture for Load Testing of Door Trim The present invention relates to a fixing device for load testing, and more specifically, to a fixing device for load testing of a door trim that can increase the convenience of the testing operation by providing a fixing clip capable of fixing a fastener coupled to the door trim, thereby enabling load testing of the door trim without separating the fastener from the door trim. Generally, door trims attached to the side of a vehicle undergo impact testing before being installed on the vehicle to check for stability against potential side collisions and impacts, as well as rigidity and load tests. In addition, the armrest structure for the door trim forms an armrest that protrudes toward the passenger compartment from the center of the door trim and is configured to support the occupant's arms, etc. It functions to absorb the impact load of the occupant through bending deformation and tensile fracture to protect the occupant during a vehicle collision. To prevent the armrest from being crushed during a collision, it is necessary to set the rigidity of the armrest low; however, in this case, deformation occurs due to loads from the occupant or thermal deformation. The method described above for testing the vertical stiffness and strength of the door trim is a test to evaluate whether deformation or breakage of the door trim armrest occurs when a passenger places their elbow on the door trim armrest and presses it with a certain load and a certain number of times. Taking these factors into consideration, the vertical stiffness and strength test is also conducted by using test equipment to apply a load a set number of times with a constant force specified in the ES-SPEC to evaluate the amount of elastic deformation, permanent deformation, and breakage. Meanwhile, conventionally, the (static) load test of a door trim involved fixing a door trim test sample to a jig and applying pressure to a specific target point of the door trim using a loader. In this conventional door trim load test, the jig to which the door trim is fixed is provided as MDF plywood, and the test is conducted by fixing the door trim and the MDF plywood by using a piece or screw to penetrate and join the door trim and the MDF plywood. Conventional door trim load tests had the problem that the fixing strength of the door trim weakened as the MDF plywood was worn down by screws or fasteners during repeated testing, and when the door trim was fixed to the MDF plywood avoiding the worn points, the fixing points could vary each time, which reduced the reliability of test reproducibility.
