Description

[0001] The invention relates to a roof module for forming a vehicle roof on a motor vehicle according to the preamble of claim 1. Furthermore, the invention relates to a motor vehicle having at least one such roof module. The invention also relates to a method for attaching a cleaning device to a roof module.

[0002] Generic roof modules are widely used in vehicle construction, as these roof modules are prefabricated as separate functional modules and can be delivered to the assembly line during vehicle assembly. The roof module forms, at least in part, a roof skin for the vehicle roof, preventing moisture or airflow from penetrating the vehicle interior. The roof skin is formed by one or more surface components, which can be made of a stable material, such as painted sheet metal or painted or dyed plastic. The roof module can be part of a rigid vehicle roof or part of an openable roof assembly.

[0003] Furthermore, developments in vehicle construction are increasingly focused on autonomous or semi-autonomous vehicles. To enable the vehicle control system to control the vehicle autonomously and / or semi-autonomously, a multitude of environmental sensors (e.g., lidar sensors, radar sensors, (multi-)cameras, etc., along with other (electrical) components) are used. These sensors detect the environment around the vehicle and, from the recorded environmental data, determine, for example, the current traffic situation. Roof modules equipped with a multitude of environmental sensors are also known as roof sensor modules (RSM). These familiar environmental sensors send and receive electromagnetic signals, such as laser beams or radar beams. Signal analysis generates a data model of the vehicle's environment, which can be used for vehicle control.

[0004] The environmental sensors for monitoring and recording the vehicle's surroundings are usually attached to the vehicle roof, as the vehicle roof is usually the highest elevation on a vehicle from which the vehicle's surroundings can be clearly seen. The environmental sensors are usually attached as an attachment to the surface component of the roof module that forms the roof skin, or they can be extended and retracted opposite the surface component. During use of the environmental sensor, there is a risk due to environmental influences (e.g., weather conditions) that a partially transparent or transparent viewing area through which the environmental sensor records the vehicle's surroundings will become dirty and at least partially opaque to the environmental sensor. This leads to at least temporary failures of the environmental sensor, which must be avoided.

[0005] Roof modules are known from the prior art that comprise a cleaning device with multiple cleaning nozzles that are individually mounted on the surface component of the roof module, often in front of the viewing area to be cleaned, as viewed in the direction of the environment sensor. Multiple openings are provided in the surface component. A cleaning nozzle is usually inserted through each of the openings from the outside and secured to the surface component on the inside, for example, clamped to it. Each of the cleaning nozzles is then connected to a fluid line to enable fluid to be supplied to the cleaning nozzle from what is often a central fluid tank. The cleaning nozzles cannot be connected to the respective fluid lines during pre-assembly, since such a fluid line can only be installed on the inside of the roof module.A functional test of the cleaning system and adjustment of the cleaning nozzles are therefore only possible after installation at the customer's / OEM's site. The cleaning nozzles apply a cleaning fluid to the viewing area to clean it in case of contamination. The installation of the cleaning nozzles is complex and often requires at least some manual assembly steps. This leads to high installation costs and long installation times. Maintenance is also complex and time-consuming.

[0006] An object of the invention is to provide an improved roof module, in particular a roof module with an improved cleaning device.

[0007] The problem is solved by a roof module having the features of independent claim 1.

[0008] The object is also achieved by a method for attaching a cleaning device to a roof module having the features of independent claim 14.

[0009] Advantageous embodiments of the invention are the subject of the dependent claims. The scope of the invention includes all combinations of at least two features disclosed in the description, the claims, and / or the figures. It is understood that the statements made regarding the roof module relate equivalently to the present motor vehicle and to the method, without being redundant for the latter. In particular, it is understood that customary linguistic transformations and / or a corresponding replacement of respective terms within the scope of common linguistic practice, in particular the use of synonyms supported by generally accepted linguistic literature, are encompassed by the present disclosure content without being explicitly mentioned in their respective formulation.

[0010] The present invention proposes a roof module for forming a vehicle roof on a motor vehicle. The roof module comprises a surface component which, at least in part, forms a roof skin of the vehicle roof, which functions in particular as an outer sealing surface of the roof module. The roof module comprises at least one viewing area and at least one environmental sensor which can transmit and / or receive electromagnetic signals to detect the vehicle's surroundings through the at least one viewing area. The roof module comprises a cleaning device for cleaning the at least one viewing area, wherein the cleaning device comprises a plurality of cleaning nozzles. In the present case, the cleaning nozzles are pre-mounted on a carrier plate. The carrier plate is in turn arranged on the surface component.

[0011] Alternatively or additionally, the problem can also be solved by a sensor module for mounting on a motor vehicle. Such a sensor module has a housing component that, at least in some areas, forms an outer skin of the motor vehicle.

[0012] The sensor module has at least one viewing area, at least one environmental sensor that can transmit and / or receive electromagnetic signals to detect the vehicle's surroundings through the at least one viewing area, and a cleaning device for cleaning the at least one viewing area. The cleaning device has a plurality of cleaning nozzles. The cleaning nozzles are pre-mounted on at least one carrier plate. The at least one carrier plate is arranged on the housing component.

[0013] All statements and examples provided below refer equivalently to the preferred sensor module, without being mentioned redundantly for this purpose. It is understood that linguistic reformulations are implicitly included and can thus be transferred to the features of the sensor module. Accordingly, for example, features mentioned with regard to the surface component can be transferred to the housing component in an equivalent form.

[0014] In its intended use, the carrier plate is preferably designed to be attached to the surface component and / or another support structure of the roof module. The individual cleaning nozzles are preferably attached, for example plugged, to one or more carrier plates during pre-assembly. This carrier plate or adapter plate is then attached, preferably during final assembly, on the inside or outside, particularly preferably with a seal, to the surface component or the housing component and / or another cover of a sensor module. This means that there is no need to arrange the individual cleaning nozzles on the surface component, which in particular enormously speeds up the final assembly process. It is particularly preferred in this case that the cleaning device can be prefabricated by pre-assembling the multiple cleaning nozzles on the carrier plate and then attaching them as a whole to the roof module with the support structure.This eliminates a large number of assembly steps, particularly for final assembly. This is particularly advantageous for an OEM, as they can, for example, purchase such pre-assembled cleaning devices and assemble them on the assembly line. For example, the carrier plate can be mounted to the surface component and / or a roof module frame with the aid of an adapter. In principle, the carrier plate itself can also form an adapter plate in order to be adaptable to different vehicle models and / or surface component models, for example. This enables simple assembly and / or disassembly of the cleaning device. In this way, at least the plurality of cleaning nozzles arranged together on the carrier plate can be assembled and / or disassembled.

[0015] The main advantages of the present invention are summarized as follows: The cleaning system can be at least largely pre-assembled in a pre-assembly process and then delivered by a supplier to a customer, who then only carries out the final assembly of the cleaning system. The cleaning system can be tested for functionality during or at least after pre-assembly. This prevents late detection of malfunctions and / or confusion of the cleaning nozzles before final assembly. The positioning of the cleaning nozzles can be customized. This can reduce tool change costs. Furthermore, the use of the carrier plate makes it possible to adjust different nozzle spray angles during pre-assembly. This eliminates the need for complex adjustment during final assembly on the vehicle for the customer. This reduces assembly time for the customer during final assembly. Potential assembly errors are also reduced.Furthermore, pre-assembly allows for complete automation of both the pre-assembly process and the final assembly of the cleaning device. Furthermore, the pre-assembly of the cleaning device eliminates the need for quick-release couplings between the respective fluid lines and the respective cleaning nozzles. This leads to a significant cost reduction.

[0016] It goes without saying that the carrier plate can basically be designed with any desired geometry. Particularly preferably, the carrier plate has at least a similar shape to the surface component to which it is mounted. The carrier plate can be plate-shaped and / or flat and / or at least partially curved and / or bent. The plurality of cleaning nozzles are preferably inserted into respective openings in the carrier plate during pre-assembly. This can generally be done from both sides, preferably viewed in a thickness direction, of the surface component. The plurality of cleaning nozzles can, for example, be clipped and / or plugged and / or clamped to the carrier plate. Screwing or gluing is also possible. The plurality of cleaning nozzles can also, in principle, be at least partially extendable and retractable relative to the carrier plate.Alternatively or additionally, the plurality of cleaning nozzles can also be arranged at least partially rigidly on the carrier plate. The individual cleaning nozzles can preferably be sealed from the carrier plate.

[0017] In a preferred embodiment, the at least one carrier plate is arranged in an opening in the surface component. The carrier plate, which can also be designed as an adapter plate, is inserted into the opening, for example. A circumferential geometry of the opening preferably corresponds to a circumferential geometry of the carrier plate, preferably including assembly-related tolerances.

[0018] In a preferred embodiment, the at least one carrier plate is arranged on the inside of an inner surface of the surface component opposite the roof skin and is inserted through the opening in the surface component, in particular such that the plurality of cleaning nozzles protrude beyond the roof skin at least for cleaning the viewing area. In other words, this means that the roof module or the preassembled cleaning device comprises a carrier plate positioned on the inside of the surface component, opposite the roof skin. The carrier plate is inserted through an opening in the surface component. This arrangement allows the cleaning nozzles to protrude beyond the roof skin to enable effective cleaning of the viewing area.The phrase "arranged on the inside of an inner surface of the surface component opposite the roof skin" means that the support plate is positioned on the inside of the surface component. The inside is opposite the roof skin. The phrase "inserted through the opening of the surface component" means that the support plate is inserted through an opening or passage in the surface component and then fixed to the surface component.

[0019] In a preferred embodiment, the at least one carrier plate is arranged on the outside on an outer surface of the surface component and inserted into the opening in the surface component, in particular in such a way that the plurality of cleaning nozzles protrude above the roof skin at least for cleaning the view-through area. In principle, it is also possible for the carrier plate to be applied to the surface component from the outside or fastened to it without the surface component comprising an opening. However, this may not be desirable with regard to the design, so that an arrangement of the carrier plate in the opening is preferred. The carrier plate can, for example, be inserted into the opening from the outside. However, in this embodiment, the carrier plate can also be fastened on the inside on the inside of the surface component. Of course, it is also possible for the carrier plate to be fastened from the outside to the surface component or the roof skin.

[0020] In a preferred embodiment, the cleaning device comprises at least one sealing element designed to seal the at least one carrier plate relative to the surface component. Whether the at least one sealing element is provided on the surface component, for example, at least partially surrounding the edge of the opening, and / or, in particular, on the edge of the carrier plate functional device, is fundamentally arbitrary. The sealing element can prevent moisture from penetrating the interior of the roof module, in particular into a dry area formed inside the roof module.

[0021] In a preferred embodiment, the at least one carrier plate is flush with the roof skin when installed. In other words, the carrier plate preferably does not protrude beyond the roof skin when installed. Only the plurality of cleaning nozzles protrude beyond the roof skin, at least in one cleaning position, for example when the plurality of cleaning nozzles are adjustably arranged on the carrier plate. In principle, it is also conceivable to arrange the cleaning nozzles on the carrier plate in such a way that at least some of the cleaning nozzles are formed by the carrier plate. The carrier plate can therefore, for example, integrally form a nozzle head of the cleaning nozzles, so that during pre-assembly only one nozzle body of the respective cleaning nozzle needs to be mounted or fastened to the carrier plate.

[0022] In a preferred embodiment, the at least one carrier plate is arranged directly or indirectly on the inner surface of the surface component or the outer surface of the surface component. The carrier plate can be arranged, for example, indirectly on the inner surface of the surface component via an assembly aid and / or an assembly guide and / or a mounting profile.

[0023] In a preferred embodiment, the carrier plate is preferably directly or indirectly screwed to the inner surface and / or glued to the inner surface and / or soldered to the inner surface and / or clamped to a molded section formed on the inner surface and / or welded to the inner surface and / or injection-molded onto the inner surface and / or overmolded together with the inner surface. In principle, other fastening options, such as a plug-in fastening, are also possible, so the above list is not intended to be limiting.

[0024] In a preferred embodiment, the cleaning device comprises a plurality of cleaning function components that are pre-assembled on the at least one support plate, in particular together with the plurality of cleaning nozzles. The cleaning device can therefore preferably comprise further components that are preferred for cleaning the viewing area. All of these components are preferably pre-assembled on the support plate in order to provide the cleaning device to the end customer as a preferably functionally ready unit.

[0025] In a preferred embodiment, the plurality of cleaning function components comprise at least one fluid line and / or at least one fluid line connector and / or at least one fluid line adapter and / or at least one valve and / or at least one pump and / or at least one compressor and / or at least one electrical connection line and / or at least one fluid power divider. The list provided here is not intended to be exhaustive, so that, in principle, other components used for cleaning a viewing area are also included, at least implicitly.

[0026] In a preferred embodiment, the carrier plate can be, for example, a housing or a housing section or a plate-shaped, trough-shaped, beam-shaped, or arched support element on which the cleaning function components and / or the cleaning nozzles can preferably be arranged. The carrier plate can also be constructed in several parts. The carrier plate can, for example, be designed as part of a housing of the at least one environmental sensor, on which the additional functional components can then be arranged, so that it can be attached to the roof module together with the housing.

[0027] In a preferred embodiment, the see-through area is arranged on the surface component or formed by it. Alternatively or additionally, the see-through area is provided on a housing of the at least one environmental sensor. For example, the surface component can form the at least one see-through area for the at least one environmental sensor, at least in part. The see-through area can be formed integrally in the surface component or, alternatively, inserted as a window in an opening in the surface component. In this case, the environmental sensor can generally be retractable and extendable relative to the surface component or can also protrude rigidly outwards beyond it.

[0028] In a preferred embodiment, the at least one environmental sensor comprises a lidar sensor and / or a camera sensor and / or a multi-camera sensor and / or an ultrasonic sensor and / or an antenna and / or an antenna module. Other environmental sensors are also conceivable, so the list mentioned here is not intended to be limiting.

[0029] In a preferred embodiment, the invention comprises a motor vehicle with a roof module according to any embodiment.

[0030] The motor vehicle preferably comprises a motor vehicle body and is characterized in that the roof module according to any embodiment forms a structural unit which is arranged on the motor vehicle body, in particular on at least one body member of the motor vehicle body.

[0031] The roof module according to the invention can, in principle, be arranged at any location on a motor vehicle and be designed for different purposes. The preferred sensor module can, in principle, be arranged at any location on a motor vehicle and / or the roof module. The carrier plate can, in principle, be arranged at any location on a motor vehicle and / or the roof module. The motor vehicle can preferably be a passenger car, a truck, a transport vehicle, a rail vehicle, an autonomously or semi-autonomously driving vehicle, a passenger transport vehicle, a military vehicle, or the like.

[0032] The present invention further claims a method for attaching a cleaning device to a roof module. The roof module comprises a surface component that forms a roof skin of the vehicle roof at least in part, at least one viewing area, and at least one environmental sensor that can transmit and / or receive electromagnetic signals to detect the vehicle's surroundings through the at least one viewing area. The method comprises the steps of: preassembling the cleaning device by arranging a plurality of cleaning nozzles on a carrier plate; arranging and / or attaching the carrier plate to the surface component.

[0033] In a preferred embodiment, step (b) comprises: (b1) arranging and / or fastening the carrier plate on the inside to an inner surface of the surface component opposite the roof skin; or (b2) arranging and / or fastening the carrier plate on the outside to an outer surface of the surface component.

It is also understood that the embodiments and examples mentioned above and those to be explained below relate in an equivalent or at least similar manner to all embodiments of the invention, without each being mentioned separately.

The roof module 10 comprises a surface component 12 for forming a roof skin 14 of the vehicle roof 100. In a front region of the vehicle roof 100 or the roof module 10, viewed in a vehicle longitudinal direction x, at least one environmental sensor 16 is arranged symmetrically to the vehicle longitudinal axis x, which environmental sensor can transmit and / or receive electromagnetic signals through at least one viewing area 18 to detect the vehicle environment. The environmental sensor 16 is according to Fig. 1 is arranged in a sensor housing 19. The environmental sensor 16 is arranged on the surface component so that it can be retracted and extended relative to the roof skin 14. Alternatively, the environmental sensor 16 can also be arranged below the roof skin 14 or below the surface component 12 and overlapped by the surface component 12, as can be seen from the Fig. 2 to 4.

[0037] The environment sensor 16 looks through a viewing area 18, which according to Fig. 1 is formed by a portion of the sensor housing 19. According Fig. 2-4, the see-through area 18 is formed on the surface component 12. The see-through area 18 can be made, for example, from a preferably shatter-proof plastic or a material that is transparent or partially transparent for the environment sensor 16. The environment sensor 16 is presently a lidar sensor. Other sensor types, e.g., multidirectional cameras and / or cameras and / or ultrasonic sensors and / or lighting devices, can also be used. The environment sensor 16 is aligned along an optical axis 20, which in the case of Fig. 1 is aligned parallel to the vehicle longitudinal direction x. The vehicle longitudinal direction x is aligned transversely, in particular orthogonally, to a vehicle width direction y.

[0038] The surroundings sensor 16 is arranged directly behind a front cross member 102, which defines a roof-side cowl of the motor vehicle 1000. The roof module 10 is preferably arranged as a structural unit on a motor vehicle body 104 of the motor vehicle. The roof module 10 can be arranged, for example, on at least one cross member 102 and / or at least one longitudinal member 106 of the motor vehicle body 104. The roof module 10 in the illustrated embodiment has a roof opening system 108. The motor vehicle further comprises a windshield 110.

[0039] The roof module 10 further comprises a cleaning device 22 for cleaning the at least one viewing area 18, wherein the cleaning device 22 has a plurality of cleaning nozzles 24. The cleaning nozzles 24 are pre-mounted on a support plate 26. The support plate 26 is arranged on the surface component 12. There are various possibilities for this arrangement of the support plate 26 on the surface component 12.

[0040] In principle, the at least one carrier plate 26 is preferably arranged in an opening 28 of the surface component 12.

[0041] As from Fig. 2, the at least one carrier plate 26 is arranged or fastened, for example, on the inside of an inner surface 30 of the surface component 12 opposite the roof skin 14 and is inserted through the opening 30 of the surface component 12, in particular in such a way that the plurality of cleaning nozzles 24 protrude beyond the roof skin 14 at least for cleaning the viewing area 18.

[0042] Alternatively, the at least one carrier plate 26 can also be arranged on the outside of an outer surface 32 of the surface component 12 and inserted into the opening 30 of the surface component 12, in particular in such a way that the plurality of cleaning nozzles 24 protrude beyond the roof skin 14 at least for cleaning the viewing area 18.

[0043] Out of Fig. 2 shows at least schematically that the cleaning device 22 has at least one sealing element 34 which is designed to seal the at least one carrier plate 26 relative to the surface component 12. Furthermore, Fig. 2 and from the Fig. 3 and Fig. 4 shows that the at least one support plate 26 in the assembled state is flush with the roof skin 14.

[0044] According to Fig. 2, the at least one carrier plate 26 is arranged indirectly via mounting profiles 36 on the inner surface 30 of the surface component 12. In the present case, the at least one carrier plate 26 is screwed to the surface component 12 using screws 38, for example. Counter-mounting sections 39 projecting on the inside are formed on the surface component 12. The mounting profiles 36 can be formed integrally on the carrier plate 26. The mounting profiles 36 can also be formed as separate components and connected to the carrier plate 26. The counter-mounting sections 39 can also be formed integrally on the surface component 12. The counter-mounting sections 39 can also be formed as separate components and connected to the surface component 12.
