Cargo compartment cover device and motor vehicle

Description

[0001] The present invention relates to a load compartment cover device for automatically covering and uncovering a loading compartment opening of a motor vehicle's cargo area. Furthermore, the invention relates to a motor vehicle with such a load compartment cover device.

[0002] Motor vehicles with cargo spaces are known in which an upper cargo space opening can be automatically covered and uncovered by a cargo space covering device. DE 101 02 792 A1 discloses a cargo space covering device with a roller cover that can be moved linearly by means of a drive device for covering and uncovering the cargo space opening. The drive device has a cable drive with a drive cable and an electric motor for driving the drive cable. Furthermore, one slat end of the roller cover is attached on each side to a linearly guided carriage. Document DE 198 25 353 C2 shows a cargo space covering device in which the drive device has a belt drive with an endless toothed belt guided over two deflection pulleys instead of a cable drive.

[0003] DE 101 23 420 A1 describes a drive for an adjustable closing element of a vehicle roof, which selectively closes or at least partially opens a roof opening. DE 10 2007 040 282 A1 shows a covering device for a motor vehicle interior with a covering sheet that can be stretched flat and rolled up onto a rotatably mounted winding shaft, on which a pull rod is arranged. Further covering devices are known from documents EP 2 289 723 A2, EP 2 028 053 ​​A1, EP 1 211 111 A1, and EP 1 182 066 A2.

[0004] Existing load compartment cover devices have the disadvantage of being highly complex and difficult to assemble. Some devices require a large number of components to be assembled during final assembly, which significantly complicates the final assembly process. Other devices are available as compact assemblies that have a relatively high overall weight and can often only be installed using complex assembly tools. This leads to longer lead times during final assembly and usually to higher manufacturing costs.

[0005] It is therefore an object of the present invention to remedy, or at least partially remedy, the disadvantages described above in a load compartment covering device. In particular, it is an object of the present invention to provide a load compartment covering device for automatically covering and uncovering a loading compartment opening of a motor vehicle's load compartment, and a motor vehicle, which have reduced complexity and / or improved assembly in a simple and cost-effective manner.

[0006] The above object is achieved by the patent claims. Accordingly, the object is achieved by a load compartment covering device for automatically covering and uncovering a load compartment opening of a motor vehicle's load compartment, having the features of independent claim 1, and by a motor vehicle having the features of independent claim 13. Further features and details of the invention emerge from the subclaims, the description, and the drawings. Features and details described in connection with the load compartment covering device according to the invention naturally also apply in connection with the motor vehicle according to the invention, and vice versa, so that, with regard to the disclosure, reference is and can always be made to the individual aspects of the invention.

[0007] According to a first aspect of the invention, the object is achieved by a load compartment cover device for automatically covering and uncovering a loading compartment opening of a cargo space of a motor vehicle. The load compartment cover device has an extendable and retractable load compartment cover for covering the cargo space, a guide device for linearly guiding the load compartment cover between an extended state in which the load compartment cover covers the cargo space and a retracted state in which the load compartment cover uncovers the cargo space, and a drive system for specifically moving the load compartment cover. The drive system has a housing. Furthermore, the drive system for moving the load compartment cover has a first flexible shaft, a second flexible shaft, and a motor for moving the first flexible shaft and the second flexible shaft.For linearly guiding the load compartment cover, the guide device has a first guide rail, a first guide carriage guided for linear movement on the first guide rail and attachable to a first cover side of the load compartment cover, a second guide rail, and a second guide carriage guided for linear movement on the second guide rail and attachable to a second cover side of the load compartment cover. The first flexible shaft is mechanically coupled to the first guide carriage, and the second flexible shaft is mechanically coupled to the second guide carriage. The drive system has a first guide tube and a second guide tube, wherein the first flexible shaft is arranged at least partially in the first guide tube and the second flexible shaft is arranged at least partially in the second guide tube.A first tube end region of the first guide tube is held on a first rail end region of the first guide rail, wherein the first rail end region is adjacent to a region of the first guide rail in which the first guide carriage is arranged in the retracted state. A second tube end region of the second guide tube is held on a second rail end region of the second guide rail, wherein the second rail end region is adjacent to a region of the second guide rail in which the second guide carriage is arranged in the retracted state. Furthermore, the drive system has a first pitot tube for receiving a first section of the first flexible shaft when the first guide carriage is moved into the retracted state and a second pitot tube for receiving a second section of the second flexible shaft when the second guide carriage is moved into the retracted state.According to the invention, a second pitot tube region of the second pitot tube pointing away from the engine is held on the first guide tube.

[0008] The load compartment cover device comprises the load compartment cover, the guide device, and the drive device. The load compartment cover is designed to cover the loading compartment opening of the load compartment in the extended state and to uncover it in the retracted state. According to the invention, the load compartment cover is preferably designed as a roller blind or slatted cover. A roller blind-like load compartment cover is preferably designed to be rollable and thus, in addition to being relatively lightweight, has a particularly small installation space. A slat-like load compartment cover is preferably designed to be rollable or foldable, preferably has a plurality of pivotably coupled transverse slats, and can be particularly stable. Alternatively, the load compartment cover can also be designed as a roller blind and have one or more transverse slats to increase stability.

[0009] The guide device is designed for linear guidance of the load compartment cover. For this purpose, the guide device has the first guide rail with the first guide carriage and the second guide rail with the second guide carriage. The guide carriages are guided linearly in the respective guide rail and are preferably held positively on the guide rail to prevent twisting or transverse movement. The guide carriages are linearly movable in the guide rails between the retracted state and the extended state. The guide carriages and / or the guide rails preferably have means for reducing friction between the guide carriages and the guide rail, such as a particularly smooth surface, hardened surface, anti-friction coating, curves or the like. The cover side of the load compartment cover is held on the guide carriages.The cover side is preferably a free end side of the load compartment cover.

[0010] The drive device is designed to move the guide carriages. For this purpose, the drive device has two flexible shafts, each of which is mechanically coupled or can be coupled to one of the guide carriages. The flexible shafts are each guided in the associated guide tube and the pitot tube. When moving the flexible shafts from the extended state to the retracted state, the flexible shafts can be moved from the guide tube into the pitot tube and vice versa. The guide tube ends of the guide tubes are held on the respective guide rails. For the linear displacement of the flexible shafts, the drive device has the motor. The motor is mechanically engaged with the flexible shafts at an engagement point directly, in particular via a gearwheel, or indirectly, in particular via a transmission, such as a gear transmission, in order to convert the rotational energy of the motor into kinetic energy of the flexible shafts.The engagement point is located between the guide tubes and the pitot tubes. The gear or transmission is preferably located in the housing. Further preferably, the flexible shafts are each guided into the housing via a guide tube and out of the housing via a pitot tube. The motor preferably protrudes from the housing with one side.

[0011] The second pitot tube region of the second pitot tube, facing away from the engine, is held on the first guide tube, for example by a plug-in connection, a clamp connection, a screw connection, an adhesive connection, or the like. A clamping device can be designed, for example, as a plug-in receptacle with one or more elastically bendable holding jaws, which are designed to move back into an initial position after being bent open. More preferably, the clamping device has a receptacle and a clamping screw or the like. The second pitot tube region is held on the first guide tube, thereby improving the pre-assembly of individual modules of the load compartment cover device. By connecting the second pitot tube region to the first guide tube, the drive device of the load compartment cover device has greater inherent stability.

[0012] A load compartment cover device according to the invention has the advantage over conventional load compartment cover devices in that it provides a particularly compact and easy-to-install load compartment cover device using simple means and in a cost-effective manner. By connecting the second pitot tube to the first guide tube, the torsional rigidity of the drive device is increased. Furthermore, this facilitates the installation of the guide tubes to the guide rails.

[0013] Preferably, a first pitot tube end of the first pitot tube, facing away from the engine, is designed as a freestanding end. In other words, it is preferred that at least the first pitot tube end, preferably the entire first pitot tube, is not directly connected to the second guide tube. The first pitot tube end and the second pitot tube end are thus designed differently from one another. This has the advantage that assembly of the load compartment cover device is simplified using simple means and in a cost-effective manner while ensuring the required inherent stability.

[0014] Alternatively, it can be provided according to the invention that a first pitot tube region of the first pitot tube pointing away from the engine is held on the second guide tube or the second rail end region. This can be realized, for example, by a plug-in connection, a clamping connection, a screw connection, an adhesive connection or the like. A clamping device can, for example, be designed as a plug-in receptacle with one or more elastically bendable holding jaws, which are designed to move back into an initial position after being bent open. More preferably, the clamping device has a receptacle and a clamping screw or the like. Preferably, the first pitot tube region is held on the second guide tube, thus improving the pre-assembly of individual modules of the load compartment cover device.The connection of the first pitot tube area to the second guide tube or the second rail end area has the advantage that the drive device of the loading space cover device has a higher inherent stability using simple means and in a cost-effective manner.

[0015] According to the invention, it is preferred that a third pipe end region of the first guide pipe and / or a fourth pipe end region of the second guide pipe is held on the housing of the drive device via a clamping device. As an alternative to a clamping connection, a form-fitting section can be formed, for example, on a pipe end region, which can be introduced into a counter-form-fitting section of the housing, for example by opening the housing, wherein the housing preferably has two housing parts that can be moved relative to one another for this purpose. The housing parts can, for example, be screwed together, clipped together, or the like. A dividing line between the housing parts preferably runs through the counter-form-fitting section. This has the advantage that assembly of the load compartment cover device is simplified using simple means and in a cost-effective manner.

[0016] Preferably, a first channel is formed in the housing for guiding the first flexible shaft from the first guide tube to the first pitot tube. Alternatively or additionally, the invention can provide for a second channel to guide the second flexible shaft from the second guide tube to the second pitot tube to be formed in the housing. A channel prevents a relative change in the position of the shaft to the gear or transmission in a direction transverse to the longitudinal extent of the shaft in the housing. This ensures that the gear or transmission always has the intended engagement depth in the shaft and that the shaft is prevented from being pushed away transversely to the longitudinal extent of the shaft. This has the advantage that the operational safety and reliability of the load compartment covering device are improved using simple means and in a cost-effective manner.

[0017] According to a preferred further development of the invention, it can be provided in a load compartment cover device that the first guide tube and / or the second guide tube is / are flexible. The first guide tube and the second guide tube are particularly preferably flexible. In the context of the invention, a flexible design is understood in particular to mean a design such that the guide tubes can be deflected by means of the flexible shaft guided therein and can thus easily yield to a transverse force load. This has the advantage that friction between the flexible shaft and the guide tube can be reduced using simple means and in a cost-effective manner, thus improving adjustment of the load compartment cover.

[0018] According to the invention, it is preferred that the first pitot tube and / or the second pitot tube be rigid. Particularly preferably, the first pitot tube and the second pitot tube are rigid. Within the scope of the invention, a rigid design is understood in particular to mean a design in which the pitot tube cannot be deflected by means of the flexible shafts guided therein. This has the advantage of improving the inherent stability and thus the mountability of the load compartment cover device using simple means and in a cost-effective manner.

[0019] Further preferably, the first guide rail has a first upper rail part and a first lower rail part, wherein a first linear guide channel with a first lateral longitudinal slot is formed between the first upper rail part and the first lower rail part, wherein the first lateral longitudinal slot is delimited by the first upper rail part and the first lower rail part on two sides, and wherein the first guide carriage is guided linearly in the first linear guide channel.Further preferably, the second guide rail has a second upper rail part and a second lower rail part, wherein a second linear guide channel with a second lateral longitudinal slot is formed between the second upper rail part and the second lower rail part, wherein the second lateral longitudinal slot is delimited on two sides by the second upper rail part and the second lower rail part, and wherein the second guide carriage is guided linearly in the second linear guide channel. Preferably, the guide rails are formed at least predominantly from the upper rail part and the lower rail part. The linear guide channel is preferably formed substantially by the lower rail part, wherein an upper channel cover of the linear guide channel is preferably formed by the upper rail part.This has the advantage of improving the ease of installation of the load compartment cover device using simple and cost-effective means. For example, the lower rail sections can be positioned on the load compartment first, allowing the guide carriage and the remaining components of the load compartment cover device to be installed in a subsequent step. The subsequent installation of the upper rail sections ensures the linear guidance of the guide carriages.

[0020] In a particularly preferred embodiment of the invention, a loading space covering device can be provided with a first carriage section of the first guide carriage being guided through the first lateral longitudinal slot. Preferably, a second carriage section of the second guide carriage is guided through the second lateral longitudinal slot. Tilting of the guide carriages about their longitudinal carriage axis can be prevented by an interaction between the carriage sections guided in the longitudinal slot and the guide rails. Further preferably, the carriage sections are guided in the respective longitudinal slot with no play or essentially no play. This has the advantage that linear guidance of the guide carriages is improved using simple means and in a cost-effective manner.

[0021] Preferably, a first end section of the first guide tube is held positively or non-positively on the first guide rail by the interaction of the first upper rail part with the first lower rail part. More preferably, a second end section of the second guide tube is held positively or non-positively on the second guide rail by the interaction of the second upper rail part with the second lower rail part. During assembly, the guide carriages with the flexible shafts attached thereto are therefore first placed on the lower rail parts, and the guide tubes can be arranged on the lower rail parts. By mounting the upper rail parts on the lower rail parts, the guide tubes are held on the guide rail. For this purpose, the end sections of the guide tubes preferably have a positive-fitting section, such as a bead, bulge or the like.The guide rail preferably has a corresponding counter-form-locking section. The form-locking section and / or the counter-form-locking section are preferably designed to be circumferential to further facilitate assembly and improve the hold of the guide tubes on the guide rails. Alternatively or additionally, the outer diameters of the guide tubes are slightly oversized compared to the guide rail receptacles, so that a clamping force can be achieved on the guide tubes when the upper rail sections are mounted on the lower rail sections. This has the advantage of further improving the assembly of the load compartment cover device using simple means and in a cost-effective manner.

[0022] Particularly preferably, the first flexible shaft is designed to independently return to a straight state or in the direction of a straight state. Further preferably, the second flexible shaft is designed to independently return to a straight state or in the direction of a straight state. Accordingly, the flexible shafts preferably have elasticity, wherein the flexible shafts are preferably relaxed in an extended, straight state. A restoring force can be built up by bending the flexible shafts. Preferably, the flexible shafts are designed to only provide a restoring force when a predefined minimum curvature is exceeded. According to the invention, it is preferred that at least the shaft section of the flexible shaft which is arranged within the guide rail in the extended state is designed in this way.This has the advantage that grinding of the flexible shaft on the guide rail can be avoided using simple means and in a cost-effective manner.

[0023] It is preferred according to the invention that a first spring device is arranged in the first flexible shaft, wherein the first spring device is designed to return the first flexible shaft to a straight state. Further preferably, a second spring device is arranged in the second flexible shaft, wherein the second spring device is designed to return the second flexible shaft to a straight state. According to the invention, it is preferred that such a spring device is arranged at least in the shaft section of the flexible shaft which, in the extended state, is arranged within the guide rail. This has the advantage that grinding of the flexible shaft on the guide rail can be avoided using simple means and in a cost-effective manner.

[0024] According to a second aspect of the invention, this object is achieved by a motor vehicle. The motor vehicle has a cargo space with an upper cargo space opening. According to the invention, the motor vehicle has a cargo space covering device according to the invention for automatically covering and uncovering the cargo space opening.

[0025] The motor vehicle according to the invention provides all the advantages already described for a load compartment cover device according to the first aspect of the invention. Accordingly, the motor vehicle according to the invention has the advantage over conventional motor vehicles that a motor vehicle is provided with a particularly compact and easy-to-install load compartment cover device using simple means and in a cost-effective manner. By connecting the guide tubes to the pitot tubes, the torsional rigidity of the drive device is increased, thus facilitating installation on the guide device.
