Description

State of the art

[0001] The invention relates to a mobile home device.

[0002] A mobile home device has already been proposed, comprising a motor vehicle body defining an interior space and having a length of 6100 mm to 6700 mm and a width of 1920 mm to 2120 mm, and comprising a rear extension module connected to a rear end of the motor vehicle body to extend the motor vehicle body and expand an interior space.

[0003] The object of the invention is, in particular, to provide a generic device with improved properties in terms of an advantageous size and a simple and advantageously insulating design. This object is achieved according to the invention by the features of claim 1, while advantageous embodiments and further developments of the invention can be found in the subclaims. Advantages of the invention

[0004] The invention is based on a mobile home device with a motor vehicle base body that delimits an interior space and has a length of 6100 mm to 6700 mm and a width of 1920 mm to 2120 mm, and with a rear extension module that is connected to a rear end of the motor vehicle base body in order to extend the motor vehicle base body and to expand an interior space.

[0005] It is proposed that the rear extension module has a base body formed from a sandwich material and an outer skin which surrounds the base body to the outside and is preferably formed from a fiber composite material.

[0006] A "mobile home device" should preferably be understood as a device that forms at least part of a mobile home, in particular a semi-integrated mobile home, or an entire mobile home. The mobile home is preferably designed as a semi-integrated mobile home. The mobile home has an interior that forms at least a living area, as well as a driving area and a bathroom area. A "motor vehicle base body" should preferably be understood as a load-bearing base body of the mobile home, which has at least a base plate, two side walls, a roof, and preferably an integrated driver's cab. The motor vehicle base body is preferably designed as a van body.The basic motor vehicle body is preferably designed as a body of a production vehicle which, in a production variant, has a rear opening at its rear, which can preferably be closed by two pivoting rear door elements. The basic motor vehicle body is designed as a body of a base vehicle. The base vehicle is preferably designed as a vehicle finished in itself by a manufacturer, in particular a van. The base vehicle is used by a motorhome manufacturer as the base vehicle and is accordingly converted into a mobile home. The base vehicle can, for example, be designed as a Mercedes Sprinter or another suitable panel van. The basic motor vehicle body preferably has a length of 6400 mm. The basic motor vehicle body preferably has a width of 2020 mm.A "rear extension module" is understood to be a module that can be permanently mounted to the rear of a motor vehicle body in order to extend the motorhome, i.e. the interior of the motorhome, towards the rear. The rear extension module is designed as a load-bearing module that is rigidly connected to the motor vehicle body. The rear extension module is intended to be rigidly mounted to the motor vehicle body. A "base body" is preferably understood to be a load-bearing base frame of the rear extension module, which is intended to absorb and transmit forces to the motor vehicle body. The base body is intended to be connected directly to the motor vehicle body. The base body is preferably formed from several rigidly connected individual elements, in particular individual plates.A "sandwich material" should preferably be understood as a flat lightweight construction element that has at least two spaced-apart cover layers, in particular an outer layer and an inner layer, and a core arranged between the two cover layers. The core of the sandwich material is preferably formed from a foam core and / or a honeycomb core. The foam core can be formed, for example, from a PU foam. In principle, it is also conceivable for the core of the sandwich material to be formed from an XPS foam. An "outer skin" should preferably be understood as a thin-walled, shaped component that closes off a housing, in particular the rear extension module, from the outside. The outer skin is preferably formed from a fiber composite material. Preferably, the outer skin is formed from a GRP or a CFRP. In principle, it would also be conceivable for the outer skin to be formed from a thin, shaped metal sheet."Intended" should be understood, in particular, to mean specially designed and / or equipped. The fact that an object is intended for a specific function should be understood, in particular, that the object fulfills and / or performs this specific function in at least one application and / or operating state. This makes it particularly easy to provide a motorhome with a particularly advantageous length.

[0007] It is further proposed that the basic motor vehicle body have a rear door bearing to which the base body of the rear extension module is mounted. A "rear door bearing" should preferably be understood to mean a bearing, in particular bearing points, for example a hinge, to which a rear door for closing the rear of the basic motor vehicle body can be mounted. In a standard equipment version of the basic vehicle, the basic motor vehicle body of which is used to form the mobile home device, a pivotable rear door is connected to a rear door bearing, via which a rear opening of the basic motor vehicle body can be closed. The rear door bearing is preferably formed by at least one bearing point, in particular a hinge unit firmly connected to the basic body.The vehicle body preferably has two rear door mountings, each of which allows a separate rear door to be mounted to the vehicle body. The rear door mountings are preferably each firmly attached to a rear end of the side walls of the vehicle body. This allows the rear extension module to be attached to the vehicle body particularly easily.

[0008] It is further proposed that the base body of the rear extension have a floor plate that, when installed, is positioned lower than a floor plate of the vehicle's base body. "Lower positioned" should be understood to mean positioned closer to a support surface. The support surface is designed as a plane on which the motorhome rests with its tires when installed. This advantageously creates a large storage space in the area of ​​the rear extension. Furthermore, loading is facilitated by the lowered floor plate.

[0009] It is further proposed that the outer skin of the rear extension module, in an assembled state, overlaps the base motor vehicle body on the outside at least in the side regions and in a roof region. In an overlap region in which the outer skin overlaps the base motor vehicle body, the outer skin covers the base motor vehicle body on an outer side by at least 1 cm, preferably at least 3 cm. Preferably, the outer skin of the rear extension module is non-positively, materially and / or positively connected to the base motor vehicle body in the region in which it overlaps the base motor vehicle body. Preferably, the outer skin of the rear extension module is adhesively bonded to the base motor vehicle body at least. Preferably, the outer skin of the rear extension module is screwed to the base motor vehicle body or positively connected in another way.In principle, it would also be conceivable for the outer skin of the rear extension module to be force-fitted to the vehicle's base body, for example, by tensioning it. This would allow the rear extension to be connected to the vehicle's base body in a particularly advantageous manner.

[0010] Furthermore, it is proposed that the outer skin be bonded to an outer side of the vehicle body. Preferably, the outer skin is bonded to the side walls and roof of the vehicle body via a continuous adhesive bead, i.e., bonded integrally. In addition to the bonding, the outer skin can be firmly connected to the vehicle body by at least one screw connection. This allows the outer skin to be connected to the vehicle body in a particularly simple and advantageous manner, ensuring a sealed connection.

[0011] It is further proposed that the rear extension module forms a storage space. A “storage space” should preferably be understood as a space at least partially delimited by the rear extension module, which is provided for stowing utensils and luggage when the motorhome is assembled. The storage space preferably has a height of at least 100 cm. More preferably, the storage space has a height between 90 cm and 110 cm, preferably between 95 cm and 105 cm. The storage space is preferably accessible from the outside through at least one lockable door or flap. The storage space is preferably accessible from an interior of the motorhome. The rear extension module can therefore be particularly advantageously designed for stowing luggage and travel items.

[0012] It is also proposed that the rear extension module have a pivoting tailgate that is connected to the outer skin and by means of which the storage space can be closed. The tailgate is preferably formed around a substantially horizontally pivoting element that, in a closed position, closes a rear opening of the rear extension module to the outside and, in an open state, releases the rear opening. The rear extension module preferably has a hinge unit that is firmly mounted to the outer skin and via which the tailgate is pivotally connected to the rear extension module. This advantageously makes the storage space accessible from the outside and particularly advantageously integrates the tailgate into the rear extension module. Drawings
