Description

The present invention relates to a vehicle camera housing comprising: at least one main housing portion having at least one receiving opening; and at least one objective lens module housing portion having at least one objective lens receptacle for at least one optical system, wherein the objective lens module housing portion is disposed in at least one of the receiving openings of the at least one main housing portion, the at least one main housing portion having at least one main contact portion; and the at least one objective lens module housing portion having at least one module contact portion that at least partially contacts the at least one main contact portion. Furthermore, the present invention relates to a vehicle camera having at least one housing on which at least one image sensor is disposed and at least one optical system aligned with at least one image sensor is disposed, wherein the at least one housing comprises at least one main housing portion having at least one receiving aperture and at least one objective lens module housing portion having at least one objective lens receptacle for at least one optical system, and the objective lens module housing portion being disposed in at least one of the receiving apertures of the at least one main housing portion, wherein the at least one main housing portion has at least one main contact portion, and the at least one objective lens module housing portion has at least one module contact portion that at least partially contacts the at least one main contact portion. Furthermore, the present invention relates to a vehicle having at least one vehicle camera, wherein the vehicle camera has at least one housing on which at least one image sensor is disposed and at least one optical system aligned with at least one image sensor is disposed, and the at least one housing comprises at least one main housing portion having at least one receiving aperture, and at least one objective lens module housing portion having at least one objective lens receptacle for at least one optical system, the objective lens module housing portion being disposed in at least one of the receiving apertures of the at least one main housing portion, the at least one main housing portion having at least one main contact portion, and the at least one objective lens module housing portion having at least one module contact portion that at least partially contacts the at least one main contact portion. DE 10 2019 113 081 A1 discloses a vehicle camera comprising a main housing and at least one objective lens module mounted on a receptacle of the main housing. The objective lens module comprises a module housing. The main housing has a housing step in its rear region. An opening forming the receptacle extends from the upper surface of the housing step, through the front of the housing step facing the opposite rear, into a cover located below the main housing. A rim surrounding the receptacle in the upper and front regions of the housing step forms a step in the contour and a support portion of the module housing. The module housing has a support rim. The support rim extends as a step corresponding to the rim of the receptacle on the upper and front surfaces of the housing step and cover. The side and rear portions of the support rim form a step in the contour corresponding to the side and support portions on the upper surface of the housing step of the main housing. The object of the present invention is to provide a housing, vehicle camera, and vehicle of the type described at the beginning, wherein the vehicle camera can be assembled more effectively, specifically, in a simpler and/or more reliable manner. In particular, the aim is to achieve the protection class required for the operation of the vehicle camera in a more reliable and simple manner. According to the present invention, this objective is achieved in the case of a housing in which at least one of the main contact portions has at least one main contact surface that is curved in at least a portion, and at least one of the module contact portions has at least one module contact surface that is curved in at least a portion and has a module contact surface that at least partially contacts the curved portion of at least one of the main contact surfaces of at least one of the main contact portions, and the curvature of the at least one curved portion of the at least one module contact surface that is in contact is the same as the curvature of the at least one curved portion of the at least one module contact surface. According to the present invention, at least one curved portion of the main contact surface contacts at least one curved portion of the module contact surface. The curved portion allows the main contact surface to be more flexibly aligned with the module contact surface to be contacted. In this way, tolerances between parts can be better compensated. Therefore, the main contact surface can be in close contact with t
