Description

[0025] An exemplary embodiment of the invention is described below. In this respect:

[0026] FIG. 1 shows an antenna apparatus;

[0027] FIG. 2 shows a fastening device;

[0028] FIG. 3 shows a further view of the fastening device; and

[0029] FIG. 4 shows a further view of the fastening device.

[0030] The exemplary embodiment explained below is a preferred embodiment of the invention. In the exemplary embodiment, the described components of the embodiment each represent individual features of the invention that should be considered independently of one another and that each also develop the invention independently of one another and can therefore also be considered to be part of the invention individually or in a combination other than that shown. Furthermore, the embodiment described can also be supplemented by further features of the invention that have already been described.

[0031] In the figures, elements with the same function are each provided with the same reference signs.

[0032] FIG. 1 shows a vehicle 1 with an antenna apparatus 2. The antenna apparatus 2 can be inserted into an antenna opening 3 which can be located in a roof panel 4 of a vehicle roof 5 of the vehicle 1. The antenna apparatus 2 can have an antenna chassis 6 and a cover 7, the antenna chassis 6 being able to bear against an underside of the vehicle roof 5. The cover 7 of the antenna apparatus 2 can at least partially protrude from the antenna opening 3 of the vehicle roof 5. In order to be able to fasten the antenna apparatus 2 to the vehicle roof 5 of the vehicle 1, the antenna apparatus 2 can have a fastening device 8. The fastening device 8 can have a locking lever 9 and a spring device 10. The locking lever 9 can be set up to fix the antenna apparatus 2 on the vehicle roof 5 in a predetermined final assembly position relative to the antenna opening 3. In order to bring the locking lever 9 into a predetermined locking position, the spring device 10 can be set up to act on the locking lever 9 with a restoring force acting in the direction of the predetermined locking position of the locking lever 9 and thereby to hold the locking lever 9 in the locking position. The spring device 10 can be braced with the vehicle roof 5 in the predetermined final assembly position. The bracing can take place in such a way that a region of the roof panel 4 is pressed against an opposite side 11 of the antenna chassis 6 by the spring device 10. A support block 11′ may be provided here. In order to be able to fix the fastening device 8 in the final assembly position of the antenna apparatus 2, a locking element 12 can be inserted in a guide channel 13 of the antenna chassis 6. The locking element 12 can thereby prevent a movement of the locking lever 9 from the predetermined locking position.

[0033] FIG. 2 shows the fastening device 8. The fastening device 8 can have the spring device 10 and the locking lever 9. The spring device 10 and the locking lever 9 can be caulked into one another via a connection 14. In order to provide the restoring force, it can be provided that the spring device 10 is designed as a wire spiral spring, with the spring ends of the spring device 10 being designed as restoring ends 15 which can be arranged on the antenna chassis 6 of the antenna apparatus 2. A pivot pin 16 can be formed on the locking lever 9 and can be inserted into a receptacle 20 of the antenna chassis 6 as shown in FIG. 3. A spiral of the spring device 10 can be arranged around the pivot pin 16 and can be set up to bring about the restoring force. The spring device 10 and the locking lever 9 can have sliding surfaces 17 which can enable the fastening device 8 to be threaded into the vehicle roof 5. The spring device 10 can provide latching edges 18 which can rest on the roof panel 4 of the vehicle roof 5 in the predetermined final assembly position. As a result, the antenna apparatus 2 can be clamped on the vehicle roof 5. In the final assembly position, the locking lever 9 can rest on the vehicle roof 5 by means of its projection 19.

[0034] FIG. 3 shows the fastening device 8 and the locking element 12 while the antenna apparatus 2 is being threaded into the antenna opening 3. Owing to the oblique sliding surfaces 17 of the fastening device 8, a force can be exerted when the antenna apparatus 2 is moved through the antenna opening 3, as a result of which the locking lever 9 can be moved out of the locking position. In this case, the pivot pin 16 can lie in a receptacle 20 of the antenna chassis 6. The locking element 12 can be arranged in a free position during threading in and not yet be arrested in the guide channel 13 of the antenna chassis 6. The locking element 12 can provide an opposite side 21 which can rotatably support the pivot pin 16 together with the receptacle 20 of the antenna chassis 6.

[0035] FIG. 4 shows the fastening device 8 in the final assembly position of the antenna apparatus 2. In the final assembly position, the roof panel 4 of the vehicle roof 5 can be pressed against an opposite side 11 of the antenna apparatus 2 by the spring device 10 . The roof panel 4 can here be located between the latching edge 18 and the opposite side 11. In the final assembly position, the locking lever 9 can be oriented in the locking position. The restoring end 15 of the spring device 10 can bear against an underside of the antenna chassis 6 and thereby provide the spring force which can hold the locking lever 9 in the predetermined locking position. In order to be able to fix the fastening device 8 in the predetermined locking position, the locking element 12 can be arranged in the guide channel 13 and thus prevent the locking lever 9 from being released from the predetermined locking position.

[0036] The invention consists in a combination of the locking lever 9 and the spring device 10 to form the fastening device 8 (spring system) by caulking the locking lever 9 with the spring device 10. The spring device 10 can be configured as a wire spiral spring, and the locking lever 9 can be configured as a sheet metal spring. The wire spiral spring enables the antenna apparatus 2 to be easily threaded into the antenna opening 3. Because of its round shape, paint on the roof panel 4 is not damaged. The spring device 10 allows the antenna apparatus 2 to be able to be pre-latched in the antenna opening 3 of the vehicle roof 5 until the locking element 12 (locking device) can be pressed in. The locking lever 9, which can be configured as a rigid sheet metal spring, is supported on the roof panel 4 in the event of a shock/crash and thus directs the forces of the impulse into the vehicle roof 5. The invention allows the antenna apparatus 2 to be mounted with one hand in the antenna opening 3 of the vehicle roof 5 with a tolerance compensation of the sheet metal thicknesses of the roof panel 4 of 0.7 to 1.2 mm. This makes it possible to withstand a mechanical shock (crash situation) of 150 g without losing the connection between the antenna apparatus 2 and the vehicle roof 5. A further use may be possible in trucks, trains and commercial vehicles, where highly integrated and stacked printed circuit boards can be used. One-hand assembly of the antenna apparatus 2 in the antenna opening 3 from inside the vehicle is made possible by the spring device 10. The spring device 10 can allow pre-latching of the antenna apparatus 2 to occur until a worker has pressed the locking element 12 (locking device) into the guide channel 13. The fastening device 8 enables tolerance compensation for different sheet metal thicknesses of the vehicle roof from 0.7 to 1.2 mm. In the event of a crash, the locking lever 9 can absorb a shock of 150 g without the antenna apparatus 2 being released from the antenna opening 3.

[0037] Overall, the example shows how two-part mounting spring locking can be provided by the invention.
