Description

[0001] The invention relates to a motor vehicle according to the preamble of claim 1 with an electric drive, the motor vehicle comprising: a radiator assembly mounted in a front region of the motor vehicle; a front hood covering the front region; and a receptacle arranged below the front hood for receiving cargo.

[0002] Such a motor vehicle is known, for example, from DE 20 2018 104 423 U1.

[0003] From DE 10 2021 129 919 A1 a motor vehicle is known, wherein the receiving container is arranged in the longitudinal and width directions above a cooling unit.

[0004] From DE 10 2017 005 904 A1, another motor vehicle is known with a receptacle arranged above a radiator which is inclined backwards in the longitudinal direction.

[0005] Furthermore, for the technological background, reference is made to DE 10 2020 001 881 A1.

[0006] In both known motor vehicles, the storage container, which can also be referred to as the frunk (front trunk), is located flat directly under the front hood. Such a storage container arrangement is typically only possible for motor vehicles with a relatively high front hood and sufficient installation space in the vertical and / or longitudinal direction of the vehicle. However, such a storage container arrangement is not possible for motor vehicles with a lower front hood (low hood height), which can also be referred to as a flat vehicle.

[0007] The object underlying the invention is to provide a motor vehicle with a receptacle in which the above disadvantages are avoided, in particular a flat or low front hood is made possible.

[0008] This problem is solved by a motor vehicle having the features of the independent patent claim. Advantageous embodiments with useful further developments are specified in the dependent patent claims.

[0009] Thus, a motor vehicle with an electric drive is proposed, the motor vehicle comprising: a radiator assembly mounted in a front region of the motor vehicle; a front hood covering the front region; and a receptacle arranged below the front hood for accommodating cargo. Provision is made for the receptacle to have a smaller dimension in the longitudinal direction of the motor vehicle than in the vertical direction of the motor vehicle, and for a front boundary wall of the receptacle to be arranged along the radiator assembly, in particular to be aligned substantially parallel to it.

[0010] This provides a receptacle that has a great depth but a small footprint. The arrangement along, particularly behind, the radiator assembly allows for a front hood with a lower hood height.

[0011] In the motor vehicle, the front boundary wall of the receiving container is designed like a grid with several through-openings distributed across the surface of the front boundary wall. This allows (cooling) air escaping from the radiator core assembly to flow into the receiving container, so that an air path behind or downstream of the radiator core assembly is not or only slightly blocked.

[0012] The receiving container can have a rear boundary wall and two lateral boundary walls, wherein the two lateral boundary walls connect the front and the rear boundary wall to one another, and wherein at least one of the lateral boundary walls is designed in a grid-like manner with a plurality of passage openings distributed over the surface of the respective lateral boundary wall.

[0013] This allows air flowing in through the front boundary wall to escape from the receiving container to the side, at least to one side or even to both sides.

[0014] In the motor vehicle, the front boundary wall can be arranged at a distance of less than 10 centimeters, in particular less than 5 centimeters, from the radiator package arrangement.

[0015] This allows the installation space in the front area of ​​the vehicle to be used optimally, so that even a vehicle with a short length in the longitudinal direction is possible with a receiving container, which is particularly advantageous for so-called small cars.

[0016] In the motor vehicle, the receptacle can be concealed or covered by the front hood and / or a separate cover element. In other words, the receptacle can have its own lid or be covered or closed only by the front hood.

[0017] In the motor vehicle, the passage openings arranged in the front boundary wall and / or in a side boundary wall can each have the same flow cross-section. In other words, the passage openings of a boundary wall can be identically designed, for example, circular, oval, or polygonal.

[0018] In the motor vehicle, the rear boundary wall can be designed as a continuous surface such that air flowing into the receiving container through the front boundary wall is deflected laterally and / or upwards, so that the air flows out of the receiving container laterally and / or upwards.

[0019] In the motor vehicle, the front boundary wall and the rear boundary wall can be inclined relative to each other such that their longitudinal distance decreases along the height direction from top to bottom. In other words, the front boundary wall and the rear boundary wall can be arranged in a V-shape.

[0020] In the motor vehicle, the receiving container can be detachably fastened in the motor vehicle in such a way that it can be removed from the motor vehicle, wherein the motor vehicle can be operated with or without the receiving container.

[0021] Further advantages and details of the invention will become apparent from the following description of embodiments with reference to the figures. Fig. 1 a simplified and schematic representation of a motor vehicle with a radiator package arrangement and receiving container; Fig. 2 a simplified and schematic perspective view of a receiving container.

[0022] In Fig. 1 shows a simplified illustration of a motor vehicle 10. The motor vehicle 10 has an electric drive 12, which is illustrated here in simplified form as a dashed rectangle.

[0023] A radiator assembly 14 is arranged or mounted in a front region FB of the motor vehicle 10. The radiator assembly 14 can have at least one heat exchanger (radiator) around which air FL flows, for example for cooling a coolant that is passed through a respective heat exchanger or for cooling / heating a refrigerant that is passed through a heat exchanger.

[0024] The front area FB of the motor vehicle is covered by a front hood 16. A receptacle 18, also referred to as a frunk (front trunk), is located below the front hood 16. It can accommodate cargo not shown here. This cargo could be, for example, a charging cable, a container with windshield washer fluid, or the like.

[0025] The receiving container 18 has a smaller extent in the longitudinal direction X of the motor vehicle 10 than in the vertical direction Z of the motor vehicle 10, wherein a front boundary wall 18v of the receiving container 18 is arranged along the radiator package arrangement 14, in particular is aligned substantially parallel thereto.

[0026] This provides a receptacle 18 that has a great depth relative to the height direction Z, while its base area (extension in the X / Y direction) is rather small. Due to the arrangement along, particularly behind, the radiator core assembly 14, a front hood 16 can be provided that has a lower hood height HH, which is illustrated purely qualitatively by the dashed line 16n.

[0027] Fig. 2 shows in a simplified and schematic perspective view an example of a possible design of the receiving container 18.

[0028] In the receiving container 18, the front boundary wall 18v is designed in a grid-like manner, wherein passage openings 20 are formed distributed in the surface of the front boundary wall 18v.

[0029] In the example shown, the passage openings 20 are oval. However, the shape of the passage openings 20 is not limited to the illustrated embodiment. The passage openings 20 can also be polygonal, in particular triangular to hexagonal, or circular or lens-shaped. It is also conceivable to combine passage openings 20 with different shapes.

[0030] In the example shown the Fig. 2, the passage openings 20 of a row of passage openings 20 arranged at a specific height (height direction Z) are offset from the passage openings 20 of the directly adjacent row (below and / or above). Such a row-by-row offset arrangement of the passage openings 20 allows for more passage openings 20 to be arranged per unit area. However, it should be noted that a regular arrangement of the passage openings (without row-by-row offset) is also possible.

[0031] The receiving container 18 has a rear boundary wall 18h and two lateral boundary walls 18s. The two lateral boundary walls 18s connect the front and rear boundary walls 18v, 18h. At least one of the lateral boundary walls 18s is designed in a grid-like manner with several passage openings 20s distributed over the surface of the respective lateral boundary wall 18s. In the example shown, only the one on the left (in Fig. 2 visible) lateral boundary wall 18s has passage openings 20s. However, it is also possible for such passage openings 20s to be arranged in both lateral boundary walls 18s.

[0032] With regard to the shape and arrangement of the passage openings 20s in a respective lateral boundary wall 20s, reference is made to the above explanations regarding the passage openings 20 in the front boundary wall 18v.

[0033] In the motor vehicle 10, as in Fig. 1, the front boundary wall 18v can be arranged at a distance of less than 10 centimeters, in particular less than 5 centimeters, from the cooler package arrangement 14, in particular measured along the longitudinal direction X.

[0034] The receiving container 18 can be opened by the front hood 16 and / or by a Fig. 2 merely indicated separate cover element 22 can be covered or covered.

[0035] The passage openings 20, 20s arranged in the front boundary wall 18v and / or in one or both of the lateral boundary walls 18s can each have the same flow cross-section. In other words, the passage openings 20, 20s can each enclose a substantially equal opening area.

[0036] The rear boundary wall is designed as a continuous surface such that air FL flowing in through the front boundary wall 18v, in particular the passage openings 20 there, is deflected laterally and / or upwards in the receiving container 18, so that the air FL flows out of the receiving container 18 laterally and / or upwards.

[0037] From the representations of the Fig. 1 and Fig. 2 also shows that the front boundary wall 18v and the rear boundary wall 18h are inclined relative to each other, at least in some sections. Their distance Avh decreases from top to bottom in the longitudinal direction X along the height direction Z.

[0038] The receptacle 18 is detachably mounted in the motor vehicle 10 so that it can be removed from the motor vehicle 10 (when the front hood 16 is open). The motor vehicle 10 can be operated with or without the receptacle 18 inserted.

[0039] By means of a receptacle 18 as described above, it is possible to optimally utilize the installation space available in the front area FB, particularly in the case of a short front area FB in the longitudinal direction X, so that even in cases of limited space, a receptacle 18 or frunk can be provided for the motor vehicle 10. Due to the saved hood height HH (dashed hood line 16n in Fig. 1) the concept of the receiving container 18 provided behind the cooler package arrangement 14, through which air FL can flow, is particularly advantageous for so-called small or compact cars as motor vehicle 10. By means of the design of the receiving container 18 with the passage openings 20, the flow path of air FL, which is to be diverted downstream from the cooler package arrangement 14, can be directly influenced.
