Description

Retractable camera mirror device The present invention relates to a retractable camera mirror device, and more specifically, to a retractable camera mirror device that enables at least one camera to move between the interior and exterior of a vehicle body. Generally, vehicles are equipped with inside mirrors to allow the driver to assess the situation behind the vehicle, and outside mirrors on both front doors to assess the situation to the sides and rear; through the field of view secured by the inside and outside mirrors, the driver identifies other vehicles or pedestrians in situations such as reversing, overtaking, and changing lanes. Recently, camera mirrors utilizing cameras have been installed instead of outside mirrors to reduce air resistance while driving and minimize the risk of damage from external impacts. Additionally, images of the vehicle's surroundings acquired by the camera mirror are displayed through a display device installed inside the vehicle, enabling the driver to easily identify other vehicles or pedestrians. Since these camera mirrors are exposed to the exterior of the vehicle body not only when the vehicle is in operation but also when it is not, there is a possibility of damage from external impact or contamination due to the ingress of foreign substances. Consequently, there is a need for measures to prevent damage and contamination of the camera mirrors when the vehicle is not in operation.
