1 shows a device (1) for the arrangement of environment sensors (2a, 2b, 2c) in a schematic representation. The device (1) consists of a housing (8) and a housing cover (26) and the environment sensors arranged therein (2a, 2b, 2c) and the electrical contacting of the environment sensors (2a, 2b, 2c) with a common connector (18) , In the interior of the housing (22), a first environment sensor (2a), a second environment sensor (2b) and a third environment sensor (2c) are arranged. The electrical connection of the environmental sensors (2a, 2b, 2c) via a housing (8) arranged common connector (18). The common plug-in connection (18) is connected to a common conductor track (20), shown in FIG. 2, which is enclosed by a potting compound (21) in order to close it Track (20) to protect against environmental influences and corrosion and seal. A connecting line (54a, 54b, 54c) branches off from the common printed conductor (20) to each environmental sensor (2a, 2b, 2c).

The first environment sensor (2a) is connected via a first connector (16a) and a first connection line (54a) to the common conductor (20) and the common connector (18). The third environment sensor (2c) is connected via a third connector (16c) and a third connecting line (54c) to the common conductor (20) and the common connector (18). In this case, both the first connector (16a) and the second connector (16c) in a common direction. The second connector (16b) of the second environmental sensor (2b) points in the opposite direction of the first and third connector (16a, 16c). The second connector (16b) is connected via a second connecting line (54b) with the common conductor (20) and the common connector (18) in connection.

The first environment sensor (2a) has a first center axis (10a) of the first detection area (12a). The first central axis (10a) is arranged at a first angle (α) with respect to the second central axis (10b) of the second detection area (12b) of the second environmental sensor (2b). The third environment sensor (2c) has a third central axis (10c) of the third detection area (12c), which is arranged at a second angle (β) with respect to the first central axis (10a) of the first environmental sensor (2a). With this orientation of the central axes (10a, 10b, 10c) of the environment sensors (2a, 2b, 2c), it is possible to use a common device (1) or a common housing (8) to cover a very large surrounding area of a vehicle (4) by means of environmental sensors (2a, 2b, 2c) and their detection areas (12a, 12b, 12c) to monitor seamlessly and over a large area. FIG. 1a shows the same device for arranging environmental sensors (1) as FIG. 1 and describes further details of this device (1). In the common housing (8), a first environment sensor (2a), a second environment sensor (2b) and a third environment sensor (2c) are arranged. The housing (8) is closed by a wave-shaped housing cover (26). The first environment sensor (2a) is vibration-decoupled from the housing cover (26) by a first elastomeric element (56a). Also between the second environment sensor (2b) and the housing cover (26) and between the third environment sensor (2c) and the housing cover (26) is in each case a second and third elastomeric element (56b, 56c) for damping and vibration decoupling of the environment sensors (2b , 2c) arranged opposite the housing (8) or the housing cover (26).

The waveform of the housing cover (26) has at least three vertical shaft portions (34a, 34b, 34c). Here, the first vertical shaft portion (34a) is aligned perpendicular to the first central axis (10a) of the first environmental sensor (2a). The second vertical shaft portion (34b) is aligned perpendicular to the second central axis (10b) of the second environmental sensor (2b), the second central axis (10b) being disposed at a first angle (α) with the first central axis (10a). The third vertical wave portion (34c) is arranged perpendicular to the third central axis (10c). In this case, the third central axis (10c) has a second angle (β) to the first central axis (10a).

FIG. 2 shows a schematic top view of a device for arranging environmental sensors (1) with a common housing (8) and a common plug connection (18) attached thereto. In the common housing (8) a first environment sensor (2a), a second environment sensor (2b), a third environment sensor (2c) are arranged. The plug opening of the first environment sensor (2a) and the third environment sensor (2c) point in a different direction than the plug opening of the second environmental sensor (2b).

The common connector (18) is connected via a common connecting line (58) with the common conductor track (20). The common conductor track (20) is connected via a first connecting line (54a) and a first plug connection (16a) to the first surroundings sensor (2a). The second environment sensor (2b) is connected via a second plug connection (16b) and a second connection line (54b) with the common conductor track (20) in connection. The third environment sensor (2c) is connected via a third plug connection (16c) and a third connection line (54c) to the common conductor track (20). Since the interior (22) of the housing (8) is in communication with the atmosphere, the common conductor track (20) is completely surrounded by environmental protection from a potting compound (21). The common conductor track (20) can alternatively be replaced by a common cable harness, which branches off from the common plug connection (18) to the individual connecting lines (54a, 54b, 54c) and the first, second and third plug connections (16a, 16b, 16c) ,

The interior space (22) communicates with the atmosphere via a first opening (24a), a second opening (24b) and / or a third opening (24c). But it is also possible to use a different opening for connecting the interior (22) with the atmosphere. The first central axis (10a) of the first environmental sensor (2a) and the third central axis (10c) of the third environmental sensor (2c) are arranged on a common plane (14), around the first detection area (12a) and the third detection area (12c) without gaps to be able to capture.

The second or the third environment sensor (12b, 12c) can be replaced by a dummy. In this case, there is no contacting of the dummy with the common conductor track (20) or the common Plug connection (18). When using a dummy, the second or third opening (24b, 24c) in the housing (8) can be closed by a blanking plug, for example in the form of a second or third elastomeric element (54b, 54c).

FIG. 3 shows a vehicle (4) with two housings (8) with devices for arranging environmental sensors. A first housing (8) is in the front area of the vehicle (4) and a second housing (8) is arranged on the right side of the vehicle (4). The first housing (8) in the front region of the vehicle has three environmental sensors, wherein the first environmental sensor has a first center axis (10a) with a first detection area (12a). The first central axis (10a) is arranged at a first angle (α) of the second central axis (10b) of the second environmental sensor and at a second angle (β) to the third central axis (10c) of the third environmental sensor. The second environment sensor has a second detection area (12b) about the second central axis (10b). The third detection area (12c) is arranged around the third center axis (10c) of the third environment sensor. The same arrangement of the central axes (10a, 10b, 10c) and their detection areas (12a, 12b, 12c) applies to the second housing (8) of the device for the provision of environmental sensors, which with its housing (8) on the right side of the vehicle (4) is arranged.

The distances between the first detection areas (12a) and the second or third detection areas (12b, 12c) are very small and practically not important, so that a total of a complete detection range of the housing (8) of the device for the arrangement of environmental sensors is achieved.

In the illustrated arrangement of the housing (8) in the front and on the right side of the vehicle (4) overlap the third detection area (12c) of the housing (8) in the front area and the second Detection area (12b) of the housing (8) on the right side of the vehicle (4). It would also be possible to dispense with one of these two detection areas (12b, 12c) and to move the housing (8) laterally either on the right side of the vehicle or in the front area of the vehicle (4) and arrange them correspondingly closer to one another. The housings (8) are fastened to the vehicle (4) by a screw connection (not shown). The connection between the housing (8) and the vehicle (4) can also be effected by an adhesive or latching connection. Of course, it is also possible to arrange a further housing (8) with at least two environment sensors on the left side of the vehicle (4).

FIG. 4 shows a front view of a vehicle (4) standing on a flat road surface (60). A housing (8) of a device (1) is arranged on the vehicle (4) in the front region, and a further housing (8) of a device (1) for arranging environmental sensors (2a, 2b, 2c) is arranged in the right-hand side region. The housing (8) in the side region of the vehicle is arranged at a sensor height (H) with respect to the road surface (60) on the vehicle (4) by means of a latching connection (not shown).

A first central axis (10a) of an environmental sensor in the housing (8) is arranged at a third angle (γ) with respect to a horizontal plane (15). In this example, the horizontal plane (15) is aligned parallel to the flat road surface (16). By the inclination of the first central axis (10a) by the third angle (γ), it is possible to detect objects in the vicinity of the vehicle or the vehicle side area. This applies in particular to objects (6) which have a height (h) of approximately 0.5 to 1 m at a distance (d) of approximately 0.5 to 1 m from the vehicle side or the outer vehicle body of the vehicle (4). This is possible even small objects, such. B. playing children or the like in the vehicle area to capture safely.
