Abstract

A roof assembly for forming a vehicle roof on a motor vehicle, the roof assembly has a panel component which forms at least sections of a roof cladding of the vehicle roof, the roof cladding acting as an outer sealing surface, and a roof opening system having a lid part which is configured to selectively open or close a roof opening provided in the panel component, and at least one electric and/or electronic and/or electromagnetic component and an air conditioner, via which waste heat released by the electronic component and/or heat introduced from outside are able to be dissipated, wherein the roof opening system has at least one water gutter via which at least one cooling channel of the air conditioner is formed, the waste heat of the component and/or the heat introduced from outside being able to be dissipated from the roof assembly via cooling channel.

First claim

The invention claimed is:

1 . A roof assembly for forming a vehicle roof on a motor vehicle, the roof assembly comprising: a panel component which forms at least sections of a roof cladding of the vehicle roof, the roof cladding acting as an outer sealing surface, and a roof opening system having a lid part which is configured to selectively open or close a roof opening provided in the panel component, and at least one electric and/or electronic and/or electromagnetic component and an air conditioner, via which waste heat released by the electronic component and/or heat introduced from outside is able to be dissipated, wherein the roof opening system comprises at least one water gutter via which at least one cooling channel of the air conditioner is formed, the waste heat of the component and/or the heat introduced from outside being able to be drained from the roof assembly via the cooling channel.

2 . The roof assembly according to claim 1 , wherein the at least one water gutter is disposed in an edge area of the roof opening, so as to surround the roof opening, and is configured to drain water entering through the roof opening via at least one rear and/or frontal and/or lateral water outlet from the roof assembly.

3 . The roof assembly according to claim 1 , wherein the air conditioner comprises at least one supply channel having a cooling-air inlet, the supply channel being coupled with the water gutter in a flow-conducting manner.

4 . The roof assembly according to claim 1 , wherein the air conditioner comprises at least one other cooling channel having a cooling-air inlet, at least sections of the at least one other cooling channel being coupled with the water gutter in a flow-conducting manner.

5 . The roof assembly according to claim 4 , wherein the at least one other cooling channel is coupled with the at least one component in a heat-conducting manner.

6 . The roof assembly according to claim 1 , wherein the at least one component is coupled with the at least one water gutter in a heat-conducting manner.

7 . The roof assembly according to claim 1 , wherein the roof opening system comprises at least one set of roof opening kinematics and at least one guide rail, in which the lid part is moveably guided linearly along the at least one guide rail for selectively opening and closing the roof opening, the at least one guide rail comprising the at least one water gutter.

8 . The roof assembly according to claim 1 , wherein a seal is provided between a sealing flange of the panel component and the lid part, the seal being configured to prevent dampness from entering through the roof opening at least in a closed position of the lid part.

9 . The roof assembly according to claim 1 , wherein the at least one water gutter comprises an abutment seal which is disposed on an edge of the water gutter and is configured to prevent dampness from entering between the water gutter and the lid part.

10 . The roof assembly according to claim 8 , wherein the cooling channel is circumferentially limited at least by the water gutter, an abutment seal, the lid part, the seal and the sealing flange in the closed position of the lid part.

11 . The roof assembly according to claim 1 , wherein the at least one electric and/or electronic component is disposed in a dry compartment of the roof assembly protected against dampness and the waste heat released by the electric and/or electronic component is dissipated from the dry compartment by the air conditioner.

12 . The roof assembly according to claim 1 , wherein the at least one air conditioner comprises at least one heat conductor and/or at least one cooling body and/or at least one heat pump.

13 . The roof assembly according to claim 1 , wherein the at least one electric and/or electronic component comprises at least an environment sensor, the environment sensor being able to transmit and/or receive electromagnetic signals for charting the vehicle environment through a see-through area.

14 . The roof assembly according to claim 1 , wherein the roof assembly comprises a roof module, which is fastened as a structural unit to a vehicle chassis.

15 . A motor vehicle, comprising a roof assembly according to claim 1 .

16 . The roof assembly according to claim 13 , wherein the environment sensor is a lidar sensor and/or a radar sensor and/or a camera sensor and/or a multi-camera sensor.

17 . The roof assembly according to claim 14 , wherein the vehicle chassis is a roof chassis frame via a roof module frame.
