The present disclosure refers to a base assembly of an exterior rear view device to be mounted to a vehicle, the base assembly comprising a base frame and at least one camera sub-assembly attached to the base frame. It also refers to a rear view device with such a base assembly, a vehicle with such a rear view device and a method for assembling such a base assembly.
A rear view device typically includes a base assembly to be attached to a vehicle and a head assembly mounted to the base assembly and being moveable relative to the base assembly. Generally the head assembly of a rear view device can be rotated between a driving position and a parking position.
The term “rear view” may refer to a view of the surrounding area, which is not in the field of view of a driver of a vehicle, i.e. the directions opposing, left, right, below and above of the viewing direction, but can also comprise the view in the direction of the viewing direction of the driver and/or any combinations of the directions. The rear view can be achieved via at least one rear view element in form of a reflective element like a mirror and/or an image acquisition means like a camera. The rear view, that is the field of view of the driver, can be adjusted by moving, in particular rotating, the reflective element and/or the image acquisition means.
The base assembly in general comprises a base frame which fulfills a multitude of functions, in particular that of supporting the head assembly and connecting the same as well as electronic components of the exterior rear view device to the vehicle and a central control unit within the vehicle. A camera is one of such electronic components, and it is common to attach such a camera via a camera cradle.
Further, the base frame is covered by one or more pieces to achieve a pleasing appearance and to adapt the exterior rear view device to the vehicle design. But the cover pieces also have to fulfill technical functions, like water drainage and the like.
It is an object of the present disclosure to further develop the known base assembly such that a camera can easily and simultaneously reliably be mounted.
This object may be achieved in that the camera sub-assembly comprises at least one camera, a camera cradle and a camera holder designed to provide clamping force and datum onto the camera.
According to an embodiment the camera is loaded into the camera cradle, wherein preferably the camera extends at least partly through a housing portion of the camera cradle, and/or the camera is clamped within the housing portion of the camera cradle, and/or a lens extends beyond an opening of the camera cradle such that the camera can obtain images through the opening.
According to another embodiment the camera cradle is clamped to the base frame, in particular both directly and via the camera holder, wherein preferably the camera cradle comprises at least one extension and/or protrusion designed to be inserted and/or clamped into a complementary recess of the base frame, and/or the camera cradle comprises at least one clips designed to be inserted and/or clamped into a complementary part of the base frame, and/or the camera cradle comprises at least one opening designed for a protrusion of the camera holder to pass through, and/or the camera cradle comprises at least one contact surface designed to be engaged by a clip of the camera holder.
In this respect it is also proposed that a first camera cradle opening extends through the camera cradle protrusion, preferably arranged in an arm extending from the camera cradle housing portion at the end opposite the opening beyond which the lens extends, and/or a second camera cradle opening is arranged in the region of the camera cradle housing portion, and/or there are two camera cradle contact surfaces, preferably arranged on two opposite lateral sides of the camera cradle housing portion, and/or the camera cradle extension is arranged in the camera cradle housing portion, and/or there are two camera cradle protrusions, preferably one arranged in the camera cradle housing portion and another in the arm extending therefrom.
It may also be that the camera holder positioning within the camera sub-assembly is achieved by its clip(s), and the camera holder locking within the camera sub-assembly is achieved by its clip(s) and protrusion(s) via clamping force.
Further, an embodiment can be characterized in that the camera sub-assembly is clamped to the base frame, and the clamped camera sub-assembly is secured via at least one screw connection, wherein preferably a screw is passed through the protrusions and/or openings of the camera holder and the camera cradle.
It may also be that the base frame has a head attachment portion designed for attaching a head assembly of the rear view device and a camera attachment portion designed for attaching the camera sub-assembly, with the head attachment portion and the camera attachment portion being arranged at opposite sides of the base frame, preferably at an end portion opposite a door attachment portion of the base frame.
Still further embodiments can comprise cover pieces designed to releasably mantle a base frame by being attached via clip, snap and/or latch connections, wherein preferably the cover pieces comprise a lower base cover, a base cover cap and an upper base cover, and/or at least one of the cover pieces provides a camera opening, and/or at least one of the cover pieces is attached to the camera sub-assembly via a clip, snap and/or latch connection.
It may also be that a base assembly according to the present disclosure comprises a glare shield surrounding the lens of the camera, in particular the lens extending through the opening of the base cover cap, and providing an opening through which the camera can obtain images, wherein preferably the glare shield is configured to be releaseably attached to at least one of the cover pieces and/or the camera cradle and/or the camera holder via at least one the via clip, snap and/or latch connection.
The present disclosure also provides an exterior rear view device with a base assembly outlined above and a head assembly moveably attached to said bas assembly.
Still further, the present disclosure provides a vehicle with at least one such exterior rear view device.
According to this disclosure, the same also provides a method for assembling a base assembly of an exterior rear view device to be mounted to a vehicle, comprising the following steps: loading a camera into a camera cradle, in particular into a camera cradle housing portion, locating a camera holder onto the camera cradle, in particular via clip, snap and/or latch connection, especially via two clips of the camera holder engaging respective contact surfaces arranged at opposite sides of the housing portion, and rotating the camera holder into the camera cradle to clip into position and clamp the camera in place, such that the camera, the camera cradle and the camera holder form a camera sub-assembly.
In line with one embodiment the method may also comprise the following steps: clamping the camera sub-assembly to a base frame of the base assembly, and securing the clamping force applied to the camera within the camera sub-assembly and the clamping force acting between the camera sub-assembly and the base frame via a further connection, in particular a screw connection.
According to the present disclosure a camera holder is assembled onto a camera cradle loaded with a camera to provide clamping force and datum onto the camera. Said clamping force is maintained and even strengthened by assembling the camera sub-assembly of the camera, the camera cradle and the camera holder on a base frame of a rear view device base assembly via a clip, snap and/or latch connection and, if necessary, a screw connection.
