Description

Technical Field

[0001] This utility model belongs to the field of vehicle testing, and more specifically, it relates to a reconfigurable vehicle testing system. Background Technology

[0002] In existing technologies, before a vehicle rolls off the assembly line, most of the vehicle's control and power components are tested and verified as a single system or on a fixed test bench. Different vehicle models require the construction of corresponding test benches to complete the relevant functional verifications, resulting in long testing cycles and high costs.

[0003] For example, publication number CN211042710U, publication date 2020-07-17, and patent title "A Universal Vehicle Test Bench and Vehicle Headlight Test System" discloses a universal vehicle test bench, which includes: a test platform, at least four vertical actuation components, at least two longitudinal actuation components, a front track adjustment assembly, and a rear track adjustment assembly. The test platform is located in the XOY plane; the at least four vertical actuation components are correspondingly located at the four corners of the test platform, each vertical actuation component has a first hinge structure at its end and its head connected to the test platform via a second hinge structure, and each vertical actuation component is extendable along its own length; the at least two longitudinal actuation components are respectively located on both sides of the test platform, each longitudinal actuation component has one end connected to the test platform via a third hinge structure and its other end provided with a fourth hinge structure; each longitudinal actuation component is extendable along its own length. The aforementioned publicly available documents can only test vehicle headlights and cannot meet the testing needs of multiple components of the entire vehicle.
