Description
technical field [0001] The present invention relates to the technical field of testing devices, and more particularly, to a testing device and a testing method for a driving system of a back-lifting mechanism. Background technique [0002] The back lift mechanism is the mechanical solution used by most passenger car tailgates, and it is also used in many mechanical structures such as high-rise building windows, and safety is of great concern; its drive systems (such as gas spring struts, electric struts, etc., The safety of the mechanical hinge) design must be verified. [0003] The gravity characteristics of the back-up mechanism are the key factors in the strength design and reliability analysis of the support parts of the back-up mechanism. The test device must be able to simulate the real gravity characteristics of the back flip mechanism, so that it can be used to accurately assess the safety and reliability of related components. [0004] The characteristics of the b...
