Definitions
- the invention relates to a roof antenna, designed and suitable for mounting on a vehicle roof of a vehicle, wherein the roof antenna has a flat bottom plate and fastening means, according to the features of the preamble of claim 1.
- This known roof antenna has a flat bottom plate, wherein the bottom plate forms a counter-holder, on which a fixing claw is fixed, and the Befest Trentskraile forms a receiving area for the fastening screw, which is free before the insertion of the fastening screw and after insertion of the fastening screw of this is filled.
- the fixing screw, the claw and the associated receiving area on the bottom plate are not quite, but arranged approximately in a central region (central center) of the bottom plate.
- the bottom plate is formed flat throughout, and the vehicle roof, on which the roof antenna is fixed to the bottom plate is flat.
- such a roof antenna can not be used in vehicle roofs having a doming (Dachbombtechnik). Namely, if the stable flat bottom plate placed in a curved portion of the vehicle roof and then closing the fasteners are actuated (for example, by tightening a mounting screw), there are undesirable roof deformations, through which the tightness in the direction of the interior below the vehicle roof is no longer guaranteed and cracks in the paint of the vehicle roof may arise, which are then rust susceptible.
- the invention is therefore based on the object to improve a generic roof antenna such that the initially described disadvantages are avoided.
- the fastening means (clearly) are arranged outside the middle region of the base plate in a first fastening region and in this fastening region at least one spacer element projecting from the base plate.
- At least one Abstandseiementes and spaced therefrom support point or bearing surface of the bottom plate on the vehicle roof bulges of the vehicle roof can be compensated in an advantageous manner.
- Different vehicle roof curvatures can be compensated by different heights of at least one Abstandseiementes. This means that a vehicle roof curvature can be compensated for in a region between a first direct contact point or direct contact area of the floor panel on the vehicle roof via the support of the floor panel over the second support area in which the spacer element is located.
- roof curvatures can be compensated for by different heights of at least one Abstandseiementes or thereby adapted in an advantageous manner.
- the base plate and thus the roof antenna is fixed in a first fastening area which is clearly located outside the middle area, wherein at least one further fastening area which is distanced therefrom is present, in which the floor panel advantageously rests selectively or over a very small area on the vehicle roof , Alternatively, it may be thought to include in these at least one further attachment region spaced from the first attachment region in which the at least one of the bottom plate
- protruding spacer element with its at least one fastening element is to be provided with further fastening means, such as a fastening screw, locking means or the like.
- further fastening means such as a fastening screw, locking means or the like.
- a simple mounting of the roof antenna on the bottom plate take place in that the locking means of the bottom plate are brought into operative connection with corresponding locking means on or on the vehicle roof or with a corresponding opening in the vehicle roof, for example then a slight pivoting of the bottom plate takes place, so that thereby the at least one spacer element comes to rest on the vehicle roof and then in this first mounting region, the corresponding fastening means can be actuated.
- These fasteners are in a particularly advantageous manner a screw, as this, the attachment process can be done very easily and very quickly. But it is also complementary or alternatively conceivable to perform the fastening means as Rastmittei to use more than a screw or make an adhesive bond or the like.
- a substantially flat bottom plate is to be understood as meaning that the bottom plate is flat (or within the scope of customary manufacturing or material tolerances.)
- the bottom plate itself to have a slight (but not significant) curvature
- the use of the spacer element is necessary and makes sense, it would therefore make no sense to use a spacer element, if the curvature of the bottom plate would be identical or close to the roof curvature.
- the at least one spacer element is designed as a rib.
- This rib has the advantage that a sufficiently large contact surface of the spacer element is provided to set up the flat bottom plate on the curved mounting surface of the vehicle roof and to ensure a permanent attachment.
- the at least one spacer element is punctiform or cylindrical in cross-section or tube-like ⁇ parallel or perpendicular to the surface of the underside of the bottom plate aligned) is formed. While by means of at least one rib tilting of the flat bottom plate is avoided on the curved vehicle roof, in principle a single point-shaped spacer may be sufficient to adapt the flat bottom plate to the vehicle roof curvature, but in this case there is a risk that the bottom plate tilts around the punctiform spacer element. This tilting movement can be compensated by suitable fastening means in the further attachment area or other aids. However, particularly preferred in the punctiform configuration of the spacer element is the two, adjacent, in particular around the fastening means around, arranged point-shaped spacer elements are provided to prevent the tilting of the bottom plate of the roof antenna with respect to the vehicle roof.
- the at least one spacer element in the direction of the longitudinal extent (longitudinal axis) of the roof antenna is arranged in front of or behind the fastening means. Due to the very large radii that cause the vehicle roof curvature (for example, in the single-digit meter range), this arrangement may be considered.
- the at least one spacer element is arranged transversely to a longitudinal extent of the roof antenna next to the fastening means.
- a tilting of the bottom plate is effectively avoided with respect to the vehicle roof and at the same time compensated for the curvature of the vehicle roof or adapted to the flat bottom plate.
- FIG. 1 An embodiment of the roof antenna according to the invention, designed and suitable for mounting on a vehicle roof of a vehicle, is shown in Figures 1 to 3 and described below.
- a roof antenna 1 is shown in a section, which is designed and suitable for mounting on a vehicle roof 2 of a vehicle.
- the roof antenna 1 has, in addition to other structural and functional features, a bottom plate 3, which is configured flat throughout. This is among other reasons why important for the solution, because such a flat bottom plate 3 can be very easily, for example, in a casting or die casting of a metallic material (for example, zinc) or in a similar manner can be made of a plastic material.
- the flat, ie planar design of the bottom plate 3 has the advantage that other elements of the roof antenna 1 can be mounted very well and without problems on the bottom plate 3. This applies, for example, to a printed circuit board which is arranged on the base plate 3 and carries antenna elements, further electronic and possibly also mechanical components.
- the vehicle roof 2 Compared to the continuous flat bottom plate 3, the vehicle roof 2 usually has a curvature, which does not allow the roof antenna 1 by means of its bottom plate 3 plane-parallel on the curved vehicle roof 2 set up and mount, as this is to roof deformations, cracks in the Paint of the vehicle roof and other disadvantages can come. Although not readily apparent in Figures 1 and 2, it is believed that the
- Curvature of the vehicle roof 2 in Figure 1 for example, a radius of 9000 mm (9 m) and in Figure 2 has a radius of 2000 mm (2 m). Even radii of the curvature of the vehicle roof 2 in this order of magnitude must be compensated if a flat bottom plate 3 is used.
- first fastening region 4 and a second fastening region 5 are provided, these two fastening regions 4, 5 being clearly spaced from one another (for example at the end of the roof antenna 1 once on the one side and once on the other side in longitudinal extension) and in front All things are clearly offset from the center of the bottom plate 3.
- this further attachment region 6 may also be suitable and designed to fix the bottom plate 3 on or on the vehicle roof 2. But it can also be thought to use this further attachment area 6 for the sealing of the roof antenna 1 and the bottom plate 3 relative to the surface of the vehicle roof 2.
- a cover 7 of the roof antenna 1 is shown below which the base plate 3, antenna elements, circuit board and other relevant elements of the roof antenna 1 are located.
- Enumeration is purely exemplary and not restrictive. In addition, it may be possible to provide not only the cover 7 but also another hood (not shown) around it.
- At least one fastening element 8 is shown, which is designed, for example, as a screw.
- the fastener 8 may also be otherwise formed, for example as a locking means or the same.
- the curvature of the vehicle roof 2 with respect to the flat bottom plate 3 is formed by the fact that the bottom plate 3 is seconded in this first mounting portion 4 spaced from the surface of the vehicle roof 2, while in the second mounting portion 5 either directly rests or spaced from the surface of the vehicle roof 2 is arranged, wherein the distances of the bottom plate in the two attachment areas 4, 5 differ from each other.
- the fastening element 8 is advantageously arranged approximately in the one end region of the roof antenna 1 on the longitudinal axis L, where two rib-shaped spacers 9 are transverse to the latter Longitudinal axis L on the bottom plate 3 are arranged.
- the spacer elements 9 not rib-shaped but punctiform design, where they not only transversely, but alternatively or additionally also in the direction of the
- Longitudinal axis L can be arranged in the area around the fastening element 8 around.
- other forms of the spacer 9 are conceivable.
- such a spacer element 9 may also be arranged annularly around the fastening element 8.
- the bottom plate 3 in this case does not rest directly on the vehicle roof, but that a latching hook 10 on the bottom plate 3 and a spring element 11 corresponding thereto, which at a cutout on the Vehicle roof 2 is fixed, can be brought into operative connection with each other.
- This causes the roof antenna 1 is placed inclined to the vehicle roof 2 in the second mounting portion 5 and provisionally fixed on the Rastmittei (latching hook 10 and spring element 1).
- the fastener 8 passes with its at least one spacer 9 in the first mounting portion 4 until the bottom of the at least one spacer element 9 comes to rest on the surface of the vehicle roof 2.
- the fastener 8 is actuated (for example, by turning the screw) or it is carried out by further pivoting a locking of the locking means in this mounting area 4.
- the roof antenna 1 is permanently fixed to the vehicle roof 2.
- Vehicle roof 2 can be permanently fixed. It is also conceivable to arrange in this fastening region 6 at least one sealing element, for example a sealing element provided circumferentially around a recess in the vehicle roof 2 in order to effect a sealing of the roof antenna 1 from the outer region of the vehicle roof 2 in the direction of the vehicle interior.
- a sealing element provided circumferentially around a recess in the vehicle roof 2 in order to effect a sealing of the roof antenna 1 from the outer region of the vehicle roof 2 in the direction of the vehicle interior.
- a single or multi-part sealing element may be arranged by means of which the outer region of the roof antenna 1 (and so that the exterior of the vehicle) with respect to the interior of the roof antenna 1 (and thus also the interior of the vehicle, namely, for example, the passenger compartment) is sealed.
- antenna elements 13 With 13 are shown schematically antenna elements 13, which can be arranged directly or with the interposition of a printed circuit board on the bottom plate 3 of the roof antenna 1. Finally, with 14 connectors are shown, via which the signal transmission can take place. Instead of the connector 14 can also be a signal transmission via cable to and from the roof antenna 1. This means that in any case in the vehicle roof, an opening (recess, bore or the like) is provided, adjacent to the corresponding openings for the fasteners in the first and second mounting portion 4, 5 (if necessary).
