The invention relates to a camera arrangement for a motor vehicle and a motor vehicle with such a camera arrangement.
In modern motor vehicles exterior rearview mirrors are increasingly being supplemented by camera arrangements or completely replaced. As is known from exterior rear view mirrors, it is desirable to move such camera arrangements into a rest position when not in use, for example when parking a vehicle, in order in particular to avoid damage. Since a pure camera arrangement, which is also referred to as a camera hood, can generally be made more compact than an exterior rearview mirror, it is preferred if the camera arrangement is stowed completely in the rest position within the motor vehicle trim, that is, the rest position represents a stowed position.
A rear view device for a motor vehicle provides an at least legally compliant image of the rear of the motor vehicle and belongs to a subset of devices for indirect vision. These provide images and views of objects that are not in the direct field of vision of a driver, that is, in directions opposite, left, right, below, and / or above the driver's line of sight. The driver's gaze may not be completely satisfactory especially in the viewing direction, for example, obstructions may be caused by vehicle parts of the own vehicle, such as parts of the body, in particular the A-pillar, the roof construction and / or the hood, and obstructions result in other vehicles and / or objects outside the vehicle, which can obstruct the view such that the driver can not completely satisfactory or incomplete capture a driving situation. In addition, it is possible that the driver is not able to grasp the situation present to him in or out of the line of sight, as it would be necessary to control the vehicle according to the situation. Therefore, a review device may also be configured to process the information according to the capabilities of the driver to enable him to best capture the situation.
Various functions and devices can be installed in rearview devices and / or controlled by means of rearview devices, in particular including cameras. Functions and devices are particularly useful for improving, extending and / or maintaining the functionality of the review device under normal or extreme conditions. In this case, heating and / or cooling devices, cleaning agents such as wipers, liquid and / or gaseous sprays, actuator means for moving the rearview device or parts thereof, such as a display, a camera system and / or parts of a camera system comprising for example lenses, filters, Light sources, adaptive optics such as deformable mirrors, sensors and / or mirrors, and / or actuator means for inducing movements of other objects, for example parts of the vehicle and / or objects surrounding the vehicle, may be included.
Furthermore, the rearview device may comprise linear guides and / or rotating wheels, such as a filter wheel, for exchanging optical elements, for example comprising lenses, mirrors, light sources, sensors, adaptive optics such as deformable mirrors and / or filters.
In rearview devices, other devices may be integrated, and / or other devices may be controlled by means of rearview devices, such as any type of light module, including an external light module, an internal light module, a headlight, a taillight, a fog lamp, a brake light , an accelerating light, a flashing light, a logo light, an apron lighting, a ground light, a puddle light, a flashlight, a navigation light, a position light, an emergency light, a headlight, a green light, a red light, a warning light, a flashing light light module, a proximity light, a search light, an information light, a display and / or the like. Other examples of functions and devices that are integrated in reviewing devices and / or controlled by reviewing devices may include, for example, a fatigue detection system, a microsleep detection system, a distance and / or speed determination system, such as a LIDAR (Light Detection and Distance Detection) system , a blind spot indication system, a lane change assistance system, a navigation assistance system, a tracking assistant system, a human-machine interaction system, an engine-machine interaction system, an emergency and precautionary assistance system, such as an accident avoidance assistance system , a countermeasure assistance system, a brake assist system, a steering assist system, an acceleration assistance system, an escape assist system including, for example, an ejection seat system, a direction indicator, a blind spot indicator, an approach system, an emergency brake system, a cargo Status display, a vehicle mode system that includes, for example, a sports mode system, an economy mode system, an autonomous-driving mode system, a sleep-mode system and / or an anti-theft system, a vehicle-locked indication system, a Vehicle Stolen Display, a Warning Signal System, a Temperature Indicator System, a Weather Indicator System, a Traffic Signal System, a Fuel Status System and / or any combination thereof.

, the European Patent No. 2202826
, the U.S. Patent No. 7,999,992
and the U.S. Patent No. 8,537,451
The camera module may also be equipped with light intensity control devices, such as the U.S. Patent Application No. 14 / 809,509
described and light amplifier amplifiers, as in U.S. Patent Application No. 09 / 771,140

can also be used for this purpose, as well as a transflector for transmitting or reflecting light based on a corresponding input signal, as in US Pat German Patent Application No. 102016106126.3
The camera module or a cover adapted to the camera module can be moved with various actuators, drives and / or a flexible path, such as in the German Application No. 102016108247.3
and the U.S. Patent Application No. 15 / 281,780
described. Furthermore, the camera module may also include cleaning elements to clean the outwardly facing and environmentally exposed optical element. The cleaning element may, for example, wipers, brushes, lips, nozzles, fans and similar elements, as shown in the European Patent Application No. 14165197.6
, of the U.S. Patent Application No. 15 / 281,780
, of the German Patent Application No. 102016108247.3
, of the European Patent Application No. 13163677.1

It is known to provide heaters for such cameras or protective glasses. For this example, heating films are glued to the protective glass or laminated with this. Such a solution is expensive to manufacture and has only a low heat output due to the low thermal mass of such a heating foil. Various heating means, such as heating coils, heaters integrated in the lens holder or enclosure, or other heating elements may be used to prevent condensation and icing on the surface of optical elements, such as in the US Pat German Patent Application No. 102016108247.3

Waterproof seals against the effects of the weather as well as the influence of washing processes with detergents, solvents and high-pressure cleaners can be used on the housing of the camera module, such as in the U.S. Patent Application No. 13 / 090,127
described. Alternatively, the housing may be made of a body made of plastic and conductive material, the conductive material being dispersed in the plastic material to form a conductive mass to allow a source of current, preferably a DC voltage source, to pass through at least two electrodes to connect with the body and to warm the body accordingly. A conductive trace may be embedded in plastic parts of the camera module, as in FIG European Patent No. 1328141
and the U.S. Patent No. 7,083,311
The camera module may comprise an energy collection system, as for example in the European Patent Application No. 09171683.7
is described. A fault detection system for electrical consumers, as in the U.S. Patent No. 8,487,633

described. In addition, HDR (High Dynamic Range) technology can be used in accordance with the U.S. Patent Application No. 14 / 830,40
, be used.
Various types of fasteners may be used to attach the camera module to the vehicle or other components, such as the snap-in connection included in the vehicle European Patent No. 2233360
From the US 2016/065 796 A1
a camera arrangement for a motor vehicle is known, in which a camera along a movement axis linearly from a rest position to an operating position is movable. To enable different viewing directions of the camera, the camera can also be rotated about its axis of motion.
The US 2009/231 430 A1
describes a camera arrangement in which a sliding sleeve is provided for moving the camera between a rest position and an operating position. The sliding sleeve can perform a linear movement, while the camera is pivotally mounted on the sliding sleeve and can be swung out of a window opening perpendicular to the axis of movement of the sliding sleeve.
The known movement mechanisms are usually very complex and require a complex mechanism, which in turn increases the necessary space.
It is therefore the object of the present invention to provide a camera assembly for a motor vehicle, which is particularly compact and simple in construction. It is a further object of the present invention to provide a motor vehicle with such a camera arrangement.
This object is achieved by a camera assembly for a motor vehicle, with a movable camera housing in which at least one camera is recorded or receivable, wherein the camera body between a stowed position in a receptacle and an operating position, in which the camera body at least partially extended from the recording is movable along a free-form curve, which preferably comprises a first, substantially translational movement section and a second, substantially rotational movement section starting from the stowed position.
The movement along a free-form curve makes it possible to realize a particularly space-saving sequence of movements, which requires significantly less installation space than, for example, a combination of purely translatory and purely rotational movement phases. Thus, both the receptacle for the camera arrangement can be kept particularly small, as well as the opening of the recording, which camera is moved to its operating position. At the same time, such a sequence of movements can also be realized particularly easily mechanically. It is also possible to vary both the geometry of the recording for the camera arrangement as well as the camera arrangement itself. In order to maintain the desired functionality, only an adjustment of the respective free-form curve is necessary. According to the invention, the free-form curve, starting from the storage position, comprises a first, substantially translatory movement section and a second, essentially rotational movement section. This also serves a space-saving movement.
The term "free-form curves" should in particular be understood to mean curves which do not have a constant radius and in particular have a continuous change in their tangential gradient or their curve radius. However, this does not have to be a free-form curve in the narrower sense, ie a curve that can not be described analytically.
By "substantially" translatory or rotational is to be understood here as meaning that the respective movement component predominates in the respective movement section.
According to the invention, it is preferred that the first movement section comprises a first translational movement component and possibly a first rotational movement component, and the second movement section comprises a second rotational movement component and optionally a second translational movement component, wherein preferably the first rotational movement component is smaller than the second rotational motion component, and the first translational motion component is greater than the second translational motion component.
Thus, both translatory and rotational components of motion can be present in each movement section. For example, it may be possible for the camera arrangement to be guided translationally to an opening in an associated receptacle and at the same time oriented by rotation relative to the opening. This not only reduces the space required for the movement compared to the prior art, but also allows a faster transfer of the camera assembly from the storage position to the operating position and vice versa.
If the camera arrangement is initially displaced in the direction of its operating position, while the correct orientation is taken by rotation only during the later course of the movement, the movement of the camera arrangement can be adapted particularly easily to different designs and also to different configurations of the motor vehicle. For example, in the event that a trailer is coupled, the displacement can be greater and the rotation can be adjusted in order to achieve a reliable viewing angle in the desired range even with a trailer.
With the invention it is also proposed that the direction of translation of the first and / or second translational movement component is substantially perpendicular to an outer surface of the outer trim part and / or extends substantially horizontally.
The camera assembly is thus brought translationally in particular at a distance from the outer panel of the motor vehicle, so that it is sufficiently spaced in its operating position of the outer panel in order to achieve the desired image angle, for example, for a retrospective function.
The axis of rotation of the first and / or second rotational movement component can differ according to the invention from the translation direction. In addition, the direction of rotation may run clockwise or counterclockwise from the stowed position to the operating position.
The rotational movement component not only allows adjustment of the angle of the camera up and down, but also a free adjustment in any direction.
With the invention it is further proposed that the camera body has a base portion and a camera receiving portion, which is angled by more than 90 ° and less than 180 °, in particular by about 100 °, to the base portion.
Furthermore, it can be provided that the freeform curve is defined by a guide slot in the receptacle. In this way, a particularly simple motion mechanism can be created, which manages with very few components and therefore is inexpensive and space-saving.
Preferred embodiments of the invention are characterized in that in the camera body, a further component is mounted or attachable, in particular in the form of a light element, preferably selected from a side limiting light, a signal light, a turn signal, a laser display, a logo lamp, a floor lamp and / or a projector, and / or in the form of a cleaning device for the camera, preferably a lens of the camera. By integrating such components can be dispensed with additional attachments. As a result, the aerodynamics of the motor vehicle is improved and weight saved.
The receptacle can be arranged or arranged according to the invention behind an outer covering part of the motor vehicle and / or an opening for the passage of the camera, preferably the camera and the further component having.
It can be provided that when passing the opening through the camera of the first movement section in the second movement section, starting from the storage position and / or from the second movement section in the first movement section, starting from the operating position is changeable.
The invention further relates to a motor vehicle with a camera arrangement of the type described above. Again, the advantages mentioned come into play.
In the following the invention and its embodiments will be described by way of example by way of example. This shows
- 1 a schematic sectional view of an embodiment of a camera assembly according to the invention in the operating position;
- 2 the camera arrangement after 1 in a schematic perspective view;
- 3 the camera arrangement after 1 in a schematic sectional view in the stowed position and the operating position;
- 4 the camera arrangement after 1 in a schematic sectional view in different operating positions;
- 5 a detail view of an embodiment of a camera assembly in the stowed position and the operating position;
- 6 a detailed view of a camera body of the camera assembly after 5 in the stowed position and the operating position; and
- 7 a schematic graph illustrating different Verschwenkpfade an embodiment of a camera assembly according to the invention between the stowed position and its operating position.
A generally designated 10 camera assembly for a motor vehicle comprises a camera body 12 with a camera recording section 14 and a base section 16 , In the camera recording section 14 which is about 100 ° towards the base section 16 Angled is a camera 18 added.
The camera body 12 is in a recording 20 an exterior trim part 22 of the motor vehicle can be received. The recording 20 has an opening 21 for the passage of at least a part of the camera body 12 on. From the in 3 stowage position shown the camera body 12 through the opening 21 be pivoted into an operating position in which the camera body 12 laterally from the outer paneling 22 stands out as in 3 represented by the solid line. The extent of protrusion depends on the desired field of view of the camera 18 from.
The movement of the camera body 12 between the stowed position and the operating position comprises a superposition of a displacement along a translation direction indicated by an arrow 24 is characterized and substantially perpendicular to an outer surface of the outer trim part 22 runs, and a clockwise rotation, as with the arrow 26 in 1 and 2 illustrated. This results in a movement along a freeform curve 28 , as in 3 shown. Free-form curves are to be understood here in particular as curves which do not have a constant radius and in particular have a continuous change in their tangential gradient or their radius of curvature.
Accordingly, the movement comprises a first movement section, in which the displacement along the arrow 24 outweighs, while in a second movement section, the rotation along the arrow 26 predominates. Such a course of movement can be achieved, for example, by a corresponding guide slot (not shown). Such a guide slot can be easily adapted to different circumstances, so that, for example, the same camera body in different vehicles with different geometry of the outer lining part 22 can be used. Also, the use in different mounting positions in the vehicle, for example as a side rearview camera or as a rear camera is possible.
4 shows examples of different possible free-form curves 28 . 30 . 32 , which can be used in different mounting positions or different component geometries application. For the sake of clarity, only the camera is in each case 18 shown in the operating position. Of course, the movement also affects the entire camera body 12 ,
It is also possible to realize different movement sequences from the same installation position in the same vehicle. For example, the camera position can be adjusted depending on whether a trailer is coupled to the motor vehicle or not.
In the 5 and 6 is an exemplary embodiment of a camera arrangement 10 again shown in more detail. The figures show the camera body 12 dashed in the stowed position and with solid lines in the operating position. This in 5 also shown outer trim part 22 is to illustrate the movement between the positions in 6 omitted.
In 7 is a schematic diagram of different path-time profiles for the movement between the stowed position and the operating position of the camera body 12 shown. This is an alternative representation of the free-form curves shown in the other figures 28 . 30 . 32 , In general, it also applies here that these courses are reversible, that is, when moving from the operating position to the stowed position, the courses or free-form curves become 28 . 30 . 32 go through in the opposite direction. Alternatively, it is also possible that during the movement from the stowed position to the operating position, a different freeform curve is passed through, as in the movement from the operating position to the stowed position.
Overall, such a camera arrangement 10 which is particularly compact, requires little space for its movement and can be easily adapted to different component geometries.
The features of the invention disclosed in the foregoing description as well as in the claims and drawings may be essential both individually and in any combination for the realization of the invention in its various embodiments.
