Description

[0001] The present invention relates to a motor vehicle. The present invention also relates to an arrangement for camping with such a motor vehicle. State of the art

[0002] In motor vehicles, it has long been common practice to regulate the temperature in the interior using an integrated air conditioning unit. Such air conditioning units typically consist of a compressor, an evaporator, a condenser, and an expansion valve. They are designed to increase occupant comfort by providing a pleasant interior temperature, regardless of external weather conditions. The tempered air is usually distributed throughout the various areas of the vehicle interior via a system of air ducts and vents.

[0003] The air conditioning system is controlled via a control unit, usually integrated into the vehicle's dashboard. The control unit allows the driver or passengers to set the desired temperature and regulate the airflow distribution.

[0004] Furthermore, it is well known that additional storage spaces are created in vehicles to increase transport capacity. Therefore, in addition to the main trunk at the rear of the vehicle, many modern vehicles also offer additional storage space at the front of the vehicle, sometimes referred to as the "frunk" (a combination of the English terms "front" and "trunk"). This additional storage space is particularly found in rear-engined vehicles or battery-electric vehicles, where the electric motor takes up less space than a conventional combustion engine. Access to this front trunk is usually via a hood that opens from the outside.

[0005] It's also known that vehicles can be adapted for camping purposes. This often involves devices such as foldable beds or tents that can be attached to the vehicle to create a sleeping area.

[0006] US 2023 / 0 312 009 A1 discloses the subject matter of the preamble of claim 1.

[0007] DE 197 56 311 A1 discloses a device for supplying warm or cold air to a motor vehicle, comprising a heat exchanger for obtaining warm air from the waste heat of the internal combustion engine of the motor vehicle and / or an air conditioning compressor operated by an internal combustion engine of the motor vehicle for obtaining cold air, as well as an air conveying device for conveying the warm or cold air into the vehicle interior, wherein a portion of the warm or cold air that can be conveyed into the vehicle interior can be diverted for heating or cooling a luggage compartment of the motor vehicle.

[0010] DE 10 2023 203 295 A1 relates to a device for regulating the indoor climate of an interior of a mobile living facility using an air conditioning unit. To propose a device that enables the indoor climate of an interior of a mobile living facility to be regulated cost-effectively and flexibly, it is proposed that the air conditioning unit be designed as a vehicle air conditioning unit of a vehicle and have at least one interface configured for detachable connection to a first end of a hose line. The hose line is configured to conduct a heat flow and is detachably connectable to the interior of the mobile living facility by a second end.

[0011] DE 2734713 A1 describes a sleeping area in the rear trunk of a vehicle. This sleeping area can be folded out when the trunk is open. Additionally, a tarpaulin is provided, which is attached to the open trunk lid and can enclose the sleeping area.

[0012] WO 2023 / 072 352 A1 describes a fold-out sleeping area in the rear trunk of a vehicle. This sleeping area can be folded out when the trunk is open. A tarpaulin is also provided, which is attached to the open trunk lid, thus creating a protected space above the sleeping area.

[0013] DE 102019126724 A1 describes a climate-controlled front trunk for an electric vehicle. This front trunk is equipped with a climate control system that regulates the temperature inside the trunk.

[0014] DE 102023113492 A1 describes a front trunk for an electric vehicle. This front trunk is equipped with an air conditioning system that can be operated independently of the vehicle's interior.

[0015] DE 202019106016 U1 describes a climate-controlled front trunk for an electric vehicle. The vehicle's air conditioning system is installed directly in the front trunk. Disclosure of the invention

[0016] One problem arises from the common separation of vehicle functions from applications for recreational activities such as camping. While modern motor vehicles offer comprehensive interior climate control, the comfort provided by these systems remains limited to the passenger compartment. Additional storage spaces, such as the front trunk of electric vehicles, are excluded from these systems and offer neither access to temperate air nor to other amenities of the vehicle interior.

[0017] For vehicle users who want to use their car not only as a means of transportation but also as an integral part of their leisure activities, especially when camping, this creates a comfort deficit. They have to forgo the benefits of air conditioning if they sleep in a tent attached to the vehicle or use the sleeping area in the trunk. This can be an unpleasant experience, especially in extreme weather conditions. Cold at night or excessive heat during the day can significantly limit the everyday suitability and comfort of these camping solutions.

[0018] Another problem is the lack of integration of vehicle functions into these leisure activities. While vehicles can be equipped with sleeping areas and tents, these are often not seamlessly integrated into the overall vehicle concept, resulting in a suboptimal user experience. The necessary handling of separate components can be cumbersome and requires additional effort for setting up and dismantling these modules, as well as for air conditioning.

[0019] The described problem is solved by a motor vehicle and an arrangement for camping with such a motor vehicle according to the independent claims.

[0020] This approach has the advantage of extending the climate control concept to the front trunk area, increasing comfort for users who want to use their vehicle for camping or similar activities. Controlling the temperature of the additional storage space and the associated sleeping area makes it possible to create a pleasant environment even under variable and extreme weather conditions.

[0021] Adapting the climate control unit to supply temperate air to the front trunk allows for seamless and comfortable use of the sleeping area and tent without forgoing the usual temperature control. This configuration expands the vehicle's usability and extends living comfort beyond the traditional interior.

[0022] By integrating a control unit in the front trunk area, the climate control can be conveniently controlled by the user without having to leave the area. This significantly simplifies operation and significantly increases the flexibility of using the vehicle.

[0023] Furthermore, the integration of climate control ducts leading to the front trunk contributes to a unified and efficient vehicle design. It eliminates the need for separate climate control units for the interior and exterior, reducing additional weight, complexity, and potentially costs.

[0024] Compared to previous solutions, which required the subsequent addition of external climate control modules to the vehicle or the acceptance of an uncomfortable environment, this concept enables a higher level of comfort and user-friendliness. This opens up new possibilities for the recreational use of motor vehicles and improves the experience for users who view their vehicle as a place of retreat and a functional extension of their living space.

[0025] Further advantageous embodiments of the invention are specified in the dependent patent claims. Short description of the drawings Fig. 1 shows the front view of a conventional electric vehicle with the front trunk open. Fig. 2 shows a schematic side view of a vehicle according to the invention with the front trunk open, a bed with support feet folded out of it and a tent pitched above it. Fig. 3 shows one of the Fig. 2 corresponding configuration in a vehicle according to the invention in a longitudinal section showing details of the air conditioning unit and air duct. Fig. 4 shows a front view of the vehicle with the front trunk open and the bed unfolded, but without the tent and support legs. Embodiments of the invention

[0026] Fig. Figure 1 illustrates the front view of a conventional electric vehicle with the front trunk lid open. Here, it is clearly visible that the trunk has an easily accessible loading sill. The user does not have to lean over the front of the vehicle to access the trunk, but can conveniently load from the front.

[0027] Fig. Figure 2 illustrates, for comparison, a motor vehicle (1) according to the invention, the hood (2) of which is open to provide access to the front trunk. A bed (4) is folded out from this front trunk and stabilized by support feet (4.1). A tent (5) is erected above the bed (4), the entrance (5.1) of which is provided at the foot end of the bed (4) facing away from the trunk. The structure of the tent (5) is held in place by tent poles (10.1, 10.2) and is fixed to the hood (2) by means of a piping rail (7) into which the piping (7.1) of the tent is inserted.
