Abstract

A roof module for forming a vehicle roof on a motor vehicle, the roof module having a panel component, which forms at least sections of a roof cladding of the vehicle roof, and having an opening in which at least one environment sensor is disposed within a casing, the environment sensor being able to transmit and/or receive electromagnetic signals for charting the vehicle environment and being displaceable between a retracted position and an extracted position, wherein the roof module may have a sealing assembly which surrounds the opening and has a sealing area which extends in a movably flexible manner between the panel component and at least one section of the casing and is injection-molded on one side on the panel component and/or the casing.

First claim

The invention claimed is:

1 . A roof module for forming a vehicle roof on a motor vehicle, the roof module having:
a panel component, which forms at least sections of a roof cladding of the vehicle roof, and having an opening in which at least one environment sensor is disposed within a casing, the environment sensor being able to transmit and/or receive electromagnetic signals for charting the vehicle environment and being displaceable between a retracted position and an extracted position, wherein the roof module comprises a sealing which surrounds the opening and has a sealing area which extends in a movably flexible manner between the panel component and at least one section of the casing and is fixed on one side on the panel component and/or the casing; and wherein the sealing assembly comprises another sealing area which is disposed so as to surround the opening and is designed to seal the opening in the retracted position of the at least one environment sensor by abutting the other sealing area against a first counter sealing section formed on the casing and to seal the opening in the extracted position of the at least one environment sensor by abutting the other sealing area against a second counter sealing section formed on the casing.

2 . The roof module according to claim 1 , wherein the sealing area is injection-molded on one side on the panel component and/or the casing.

3 . The roof module according to claim 2 , wherein the sealing area is injection-molded in one piece on one side on the panel component and/or the casing via a two-component or multi-component injection-molding method.

4 . The roof module according to claim 1 , wherein the sealing area is injection-molded in one piece on one side on the panel component via a glass injection-molding method.

5 . The roof module according to claim 1 , wherein the sealing area comprises at least one drain and is designed to collect liquid entering through the opening in the direction of the at least one drain.

6 . The roof module according to claim 5 , wherein the at least one drain is injection-molded on the sealing area.

7 . The roof module according to claim 1 , wherein the sealing area is essentially bag-shaped and is formed so as to surround the opening.

8 . The roof module according to claim 7 , wherein the sealing area defines a wet area of the roof module surrounding the opening and forms a separation barrier to a dry area of the roof module in which the environment sensor is disposed.

9 . The roof module according to claim 1 , wherein the sealing area is made of a flexible, mat-shaped material made of rubber or a liquid-proof textile.

10 . The roof module according to claim 1 , wherein the sealing area is designed in the form of a water skin.

11 . The roof module according to claim 1 , wherein the sealing area has a first edge area which is injection-molded on an edge section of the panel component, which is provided around the opening, so as to be liquid-proof by an injection-molding tool.

12 . The roof module according to claim 11 , wherein the sealing area has a second edge area which is injection-molded on the at least one section of the casing of the environment sensor so as to be liquid-proof.

13 . A method for fixating a sealing assembly on a roof module according to claim 12 , the method comprising at least the following steps: injection-molding the first edge area on the edge section of the panel component, which is provided around the opening, by a manually actuated or partially automatic or automatic injection-molding tool; and/or injection-molding the second edge area on the at least one section of the casing of the environment sensor by a manually actuated or partially automatic or automatic injection-molding tool.

14 . The method according to claim 13 , the injection-molding of the first edge area on the edge section of the panel component and/or the injection-molding of the second edge area on the at least one section of the casing of the environment sensor taking place via a two-component or multi-component injection-molding method and/or a glass injection-molding method whereby the edge area is connected to the edge section of the panel component and/or the second edge area is connected to the at least one section of the casing in one piece.

15 . The roof module according to claim 1 , wherein the at least one environment sensor is rotatable about a rotational axis between the retracted position and the extracted position.

16 . The roof module according to claim 1 , claims, wherein the at least one environment comprises a lidar sensor and/or a radar sensor and/or a camera sensor and/or a multi-camera sensor and/or an ultrasound sensor.

17 . A motor vehicle, comprising a roof module according to claim 1 .

18 . A roof module for forming a vehicle roof on a motor vehicle, the roof module having:
a panel component, which forms at least sections of a roof cladding of the vehicle roof, and having an opening in which at least one environment sensor is disposed within a casing, the environment sensor being able to transmit and/or receive electromagnetic signals for charting the vehicle environment and being displaceable between a retracted position and an extracted position, wherein the roof module comprises a sealing which surrounds the opening and has a sealing area which extends in a movably flexible manner between the panel component and at least one section of the casing and is fixed on one side on the panel component and/or the casing; wherein the sealing assembly comprises another sealing area which is disposed so as to surround the opening and is designed to seal the opening in the retracted position of the at least one environment sensor by abutting the other sealing area against a first counter sealing section formed on the casing and to seal the opening in the extracted position of the at least one environment sensor by abutting the other sealing area against a second counter sealing section formed on the casing; and wherein the other sealing area comprises a tube seal which is disposed in an edge area of the opening and is made in one piece.

19 . A roof module for forming a vehicle roof on a motor vehicle, the roof module having:
a panel component, which forms at least sections of a roof cladding of the vehicle roof, and having an opening in which at least one environment sensor is disposed within a casing, the environment sensor being able to transmit and/or receive electromagnetic signals for charting the vehicle environment and being displaceable between a retracted position and an extracted position, wherein the roof module comprises a sealing which surrounds the opening and has a sealing area which extends in a movably flexible manner between the panel component and at least one section of the casing and is fixed on one side on the panel component and/or the casing; and wherein the sealing area forms at least sections of a funnel-shaped section, which flows into the drain for collecting the leaking liquid.
