Description

[0001] The invention relates to a vehicle with a ventilation device comprising: a front section with a cross member for fastening and supporting a windshield of the vehicle and a cross member for fastening and supporting a front wall of the vehicle; and a ventilation device arranged in the front section with an air distribution unit, which is designed to distribute, in particular, tempered air into an interior of the vehicle, and an air supply unit, which is designed to supply air to the air distribution unit.

[0002] From the document DE 11 2018 001 353 T5 an air conditioning system for a vehicle is known with a temperature control unit that controls a temperature of air that is blown into a cabin of the vehicle.

[0003] From the document JP 2008 126 800 A, an automotive air conditioning system with a cooling circuit module unit is known in which at least one condenser and one evaporator, which form a cooling circuit of the automotive air conditioning system, are formed in one piece.

[0004] From the document US 2019 / 0 210 422 A1 an air conditioning system is known which is arranged in a front section of a vehicle and is separated from the cabin space by a dashboard wall.

[0005] DE 196 32 714 A1 discloses a motor vehicle with a water tank and a dashboard module. The water tank module forms a double-walled partition between the passenger compartment and the engine compartment, thus creating a separate compartment.

[0006] From the document DE 103 43 695 A1, a vehicle air conditioning system is known with an air conditioning unit housing intended to accommodate air conditioning components, in particular a refrigerant evaporator.

[0007] From the document DE 29 46 487 A1 a motor vehicle with a front engine is known in which a heating and / or air conditioning unit is held fixed to the vehicle by means of a support in a transition area between the engine compartment and the passenger compartment.

[0008] From the document EP 0 281 457 A1 a method for mounting a device for heating and / or air conditioning a passenger compartment on a transverse wall separating the passenger compartment and a front engine compartment of a motor vehicle is known.

[0009] From the document DE 103 35 174 A1 an air conditioning system for a motor vehicle with a heater, an evaporator, an air intake, a fan and an air distribution system is known.

[0010] A placement configuration for HVAC units for electric vehicles is known from US 2019 / 0210422 A1. In this case, a vehicle comprises a front compartment, a passenger compartment, a vehicle body, and an HVAC unit.

[0011] A key focus in air conditioning technology for modern vehicles is increasing comfort. New vehicle concepts, such as battery-powered electric vehicles (BEVs), require tailored solutions. Autonomous driving, in particular, presents a further challenge.

[0012] A conventional ventilation system (or air conditioning system) comprises an air distribution unit and an air supply unit. In motor vehicles (MVs), the air distribution unit is located in the interior of the vehicle, i.e., behind a bulkhead that separates the interior from the front section of the vehicle. This requires more space in the vehicle interior, which can impair passenger comfort, especially in autonomous driving.

[0013] The object underlying the invention is seen in providing a vehicle with a ventilation device which is arranged in the vehicle in such a way that more interior space is provided for a passenger.

[0014] This object is achieved by a vehicle with a ventilation device having the features of patent claim 1 and by a ventilation device having the features of claim 9. Advantageous embodiments with expedient further developments are specified in the dependent patent claims.

[0015] The invention therefore proposes a vehicle with a ventilation device comprising: a front section with a cross member for fastening and supporting a windshield of the vehicle and a cross member for fastening and supporting a front wall of the vehicle; and a ventilation device arranged in the front section with an air distribution unit, which is designed to distribute, in particular, tempered air into an interior of the vehicle, and an air supply unit, which is designed to supply air to the air distribution unit. Provision is made for the air distribution unit to be arranged in the front section such that a front end of the air distribution unit, in the vehicle longitudinal direction extending from the front section to a rear section of the vehicle, lies in front of the cross members, in particular at a distance from the cross members of at least 10% of a total length of the air distribution unit.

[0016] This arrangement moves the air distribution unit further forward, i.e., toward the front of the vehicle, creating more interior space. This provides greater passenger comfort, especially during autonomous driving.

[0017] Furthermore, a rear end of the air distribution unit extends into the interior of the vehicle so that the tempered air can be directed into the interior.

[0018] The air distribution unit comprises a housing, with a front edge of the housing being spaced from the cross members at a distance of 10% to 50% of the total length of the air distribution unit housing. This allows for optimal "forward positioning" of the air distribution system, depending on requirements.

[0019] The vehicle may further comprise a drive unit arranged in the front section, wherein the air distribution unit is further arranged in the front section such that the front edge of the housing is located in front of a rear end of the drive unit.

[0020] In this context, the air supply unit may further be arranged in the front portion such that it is arranged above the drive unit in a vertical direction of the vehicle.

[0021] The ventilation device can be arranged substantially centrally in the transverse direction of the vehicle, thereby enabling an even distribution of the tempered air.

[0022] Furthermore, the vehicle can have a side air duct arranged in the front section with a fresh air flap and a further air duct arranged in the front section with a recirculation flap.

[0023] The air supply unit can be connected to the side air duct and the additional air duct. It can draw in fresh air from the side between the windshield and the hood of the vehicle via the side air duct and draw in recirculated air from the vehicle's interior via the additional air duct. This creates a closed air intake system.

[0024] The vehicle may also have a control device for controlling the fresh air flap and the recirculated air flap. Thus, the supply of fresh air and / or recirculated air can be controlled and, if necessary, adjusted by controlling the respective flap.

[0025] The vehicle may have a suspension strut device arranged in the front section, wherein the air supply unit is further arranged in the front section such that a front end of the air supply unit is located in front of the suspension strut device.

[0026] The above object is also achieved by a ventilation device for a vehicle having an air distribution unit configured to distribute, in particular, tempered air into an interior of the vehicle; and an air supply unit configured to supply air to the air distribution unit. The air distribution unit is dimensioned such that, in an installed state, it is arranged in a front section of the vehicle such that a front end of the air distribution unit, in the longitudinal direction of the vehicle, lies in front of cross members of the vehicle arranged in the front section.

[0027] This places the air distribution unit further forward in the front section, allowing for more interior space in the vehicle.

[0028] In this case, a front edge of a housing assigned to the air distribution unit can have a distance from the cross members of 10% to 50% of a total length of the housing of the air distribution unit.

[0029] The air supply unit may further comprise a laterally connected air duct which is designed such that, in an installed state, fresh air is sucked in from the side of the vehicle.

[0030] The air distribution unit may comprise a heat exchanger and at least one air outlet.

[0031] The air supply unit may further comprise a fan and a filter.

[0032] Further advantages and details of the invention will become apparent from the following description of embodiments with reference to the figures. Fig. 1a is a simplified schematic diagram of an embodiment of a vehicle with a ventilation device; and Fig. 1b a simplified schematic plan view of an embodiment of the vehicle.

[0033] In Fig. 1a shows a simplified schematic diagram of an embodiment of a vehicle F with a ventilation device 10. Shown here is a front section FA of the vehicle F, which has a ventilation device 10 comprising an air distribution unit 12 and an air supply unit 14. The air distribution unit 12 distributes tempered air TL in an interior of the vehicle F. This is shown in Fig. 1b, which shows a schematic top view of vehicle F, simplified by arrows. This can be heated air for heating or cooled air for air conditioning the interior.

[0034] The front section FA of the vehicle further comprises a cross member QT1 for fastening and supporting a windscreen of the vehicle F (a so-called windscreen cross member) and a cross member QT2 for fastening and supporting a bulkhead of the vehicle F (a so-called bulkhead cross member). The cross member QT2 is connected, for example, at its respective end to an A-pillar of the vehicle F (not shown). Fig. 1a and Fig. 1b) to create a continuous support in the transverse direction QR of the vehicle F. The cross members QT1, QT2 can be designed differently and form, together with other components (such as a Fig. 1b shown spring strut assembly 18) the vehicle body. In Fig. 1a further shows a high-voltage battery 20 arranged on an underside of the vehicle F.

[0035] As from Fig. 1a and Fig. 1b, the air distribution unit 12 is arranged in the front section FA in such a way that a vehicle longitudinal direction FLR, which extends from the front section FA to a rear section (not in Fig. 1a and Fig. 1b) of the vehicle, the front end 12_1 of the air distribution unit 12 is located in front of the cross members QT1, QT2, in particular having a distance from the cross members of at least 10% of a total length of the air distribution unit 12.

[0036] As a result, the air distribution unit 12 is shifted further into the front section FA of the vehicle F, i.e., further forward. This allows for more interior space, which provides greater comfort. This arrangement provides a passenger with more freedom of movement, particularly during autonomous driving of the vehicle F.

[0037] A rear end 12_2 of the air distribution unit 12 can extend into the interior of the vehicle F, which in Fig. 1b is shown schematically.

[0038] In this context, the air distribution unit 12 may further comprise a housing, wherein a front edge 12_K1 of the housing has a distance from the cross members QT1, QT2 of 10% to 50% of a total length of the housing of the air distribution unit 12. In Fig. 1a and Fig. Figure 1b shows a simplified illustration of the air distribution unit 12 and the housing associated with it. The housing can be designed and shaped according to requirements. The same applies to the air supply unit 14.

[0039] The vehicle F may further comprise a drive unit 16 arranged in the front section FA for operating the vehicle F. In one embodiment, the air distribution unit 12 is further arranged in the front section FA such that the front edge 12_K1 of the housing lies in front of a rear end 16_2 of the drive unit 16, which is simplified in Fig. 1a is illustrated.

[0040] In a further embodiment, the air supply unit 14 can be arranged in the front section FA in such a way that it is directed in a vertical direction HR of the vehicle F, which Fig. 1b is indicated by a corresponding arrow, is arranged above the drive unit 16.

[0041] Likewise, the ventilation device 10 can be arranged substantially centrally in the transverse direction QR of the vehicle F. The transverse direction is in Fig. 1b, also indicated by an arrow. This ensures a uniform distribution of the tempered air TL throughout the interior of the vehicle F.

[0042] The vehicle F further comprises a side air duct L1 arranged in the front section FA with a fresh air flap KL1 and a further air duct L2 arranged in the front section FA with a recirculation flap KL2. In the Fig. In the example shown in Figure 1b, the air ducts L1 and L2 as well as the fresh air flap KL1 and the recirculated air flap KL2 are arranged in the area of the air supply unit 14. Corresponding arrows indicate an opening direction of the corresponding flaps KL1, KL2. Furthermore, the second air duct L2 extends into the interior of the vehicle F, thus enabling a corresponding supply of recirculated air. Fig. However, the arrangement of the air ducts L1, L2 shown in Figure 1b is only an example. Other arrangements are possible. For example, the air duct L2 can be arranged on a side of the air supply unit 14 opposite the air duct L1.

[0043] The air supply unit 14 can be connected to the side air duct L1 and the additional air duct L2. Fresh air can be drawn in from the side between the windshield and the hood of the vehicle F via the side air duct L1. Furthermore, recirculated air can be drawn in from the interior of the vehicle F via the additional air duct L2. This creates a closed air intake, which is illustrated in simplified form by arrows in the air ducts L1, L2.

[0044] To control the fresh air flap KL1 and the recirculated air flap KL2, the vehicle F can also have a control device (not included in Fig. 1a and Fig. 1b) to control the respective flap KL1, KL2.

[0045] The vehicle may also include a spring strut assembly 18 arranged in the front section FA for absorbing static forces in the form of the body weight and for supporting dynamic driving forces. The air supply unit 14 is further arranged in the front section FA such that a front end 14_1 of the air supply unit 14 is located in front of the spring strut assembly 18.

[0046] Fig. 1a and Fig. 1b also shows a ventilation device 10 for a vehicle F with an air distribution unit 12, which distributes, in particular, tempered air TL into an interior of the vehicle F. Furthermore, the ventilation device 10 has an air supply unit 14, which supplies air to the air distribution unit 12.

[0047] The air distribution unit 12 is dimensioned such that, in an installed state, it is arranged in a front section FA of the vehicle F such that a front end 12_1 of the air distribution unit 12 in the vehicle longitudinal direction FLR lies in front of cross members QT1, QT2 of the vehicle F arranged in the front section FA.

[0048] As a result, the air distribution unit 12 is pushed further forward into the front section FA, thereby achieving a volume gain in the interior of the vehicle.

[0049] Furthermore, a front edge 12_K1 of a housing associated with the air distribution unit 12 can have a distance from the cross members QT1, QT2 of 10% to 50% of a total length of the housing of the air distribution unit 12. As previously described, the housing of the air distribution unit 12 (as well as a housing associated with the air supply unit 14) can be configured as desired.

[0050] In a further embodiment, the air supply unit 12 may comprise a laterally connected air duct L1 which is designed such that, in an installed state, fresh air is sucked in from the side of the vehicle F.

[0051] The air distribution unit 12 can have a heat exchanger and at least one air outlet for generating and distributing the tempered air TL (not shown in Fig. 1a and Fig. 1b).

[0052] The air supply unit 14 may further comprise a fan and a filter (not shown in Fig. 1a and Fig. 1b).
