Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted camera simulation test, and in particular relates to a vehicle-mounted camera simulation test device. Background Art

[0002] The future development trend of automobiles is smart cars or driverless cars, which requires on-board cameras to accurately judge the target objects in the scene ahead and provide the car ECU with the speed and distance of the target objects for safety warning. The function of on-board cameras in automobiles to present video and audio in real time provides a more scientific basis for our traffic accident handling and positioning, and fully protects our property and life safety.

[0003] Authorization announcement number: CN213056933U, authorization public number date: 2021.04.27 "A set of autonomous driving simulation test equipment", includes an installation frame, a buffer support structure, a clamping structure, and a transverse clamping structure. The utility model realizes all-round clamping and fixation of the camera by setting a buffer support structure, a clamping structure, and a transverse clamping structure, which effectively improves the stability of the camera installation. The setting of the spring block and the support plate realizes the longitudinal support of the camera. The spring block and the protective pad can play a protective role, extend the service life, and reduce the economic cost. The spring can play a buffering role for the camera during the installation process. The transverse clamping plate realizes transverse clamping under the elastic force of the tension spring. At the same time, the coordinated use of the limit rod and the limit groove realizes the limitation of the pull rod position. This application is improved on the basis of the existing fixation with a single locking screw, further improves the stability of the camera installation, and improves the working efficiency of the camera.
