Description

Technical Field

[0001] The invention belongs to the technical field of whole vehicle collision test monitoring, and in particular relates to a vehicle-mounted camera motion image acquisition device for whole vehicle collision test. Background Art

[0002] Vehicle crash testing is a crucial component of vehicle safety performance development. Through vehicle-to-barrier collision tests, testers observe and analyze data collected during the tests to assess and evaluate vehicle safety performance in areas such as vehicle structure, occupant injury, and airbag and curtain airbag protection. Therefore, image acquisition quality is crucial to the accuracy of test result analysis.

[0003] Throughout the test, onboard cameras positioned at different angles inside the passenger compartment should be used to capture motion images, allowing observation of the airbag deployment process and the occupants' movements during a collision. However, due to the airtightness of the cockpit, external cameras and lighting systems typically cannot capture and illuminate the cockpit environment effectively, and ground-based cameras cannot meet the tester's requirements for image capture quality and location. Therefore, in full-vehicle collision tests, a motion image capture device with an onboard camera is required that can be installed inside the passenger compartment and provide excellent capture and lighting effects. The device can also freely adjust the capture and lighting range to suit different types of collision tests and the different locations the tester wishes to observe.

[0004] Existing lighting systems can adjust the deflection angle horizontally, but this structure only illuminates horizontally, failing to effectively illuminate and photograph the lower areas of the passenger compartment. Furthermore, installation requires the removal of the rear seat headrests, hindering the installation and evaluation of rear-seat dummies. Furthermore, existing light adjustment brackets, while capable of rotating the adjustment plate during testing to adjust the illumination area and intensity, only adjust the illumination range and intensity within a fixed area and are unable to meet wide-area lighting requirements.
