Description

Motor vehicle with one in the stem area

arranged load pick-up

The invention relates to a motor vehicle according to the preamble of claim 1 and a motor vehicle according to claim 2.

A motor vehicle with a front structure is known from DE 10 2008 039 972 A1, the front structure forming a trunk recess on the front. Such front trunk recesses have the disadvantage that only an insufficient loading and

Unloading comfort is made available because the load has to be lifted over a front area of the vehicle, for example a front mask. In particular with deep trunk troughs, loading with the cargo is only possible if the person who is moving the cargo is in an anatomically disadvantageous back position and thus exposes himself to health risks.

In order to make loading and unloading easier, the

DE 10 2017 004 263 A1 specifies that in the loading space arranged on the front

Height-adjustable cargo floor is to be arranged, especially one

Height-adjustable cargo area tub with integrated loading edge protection. The height adjustability of the cargo area floor or the cargo area trough is realized by a scissor lift table arranged in the cargo area.

It is an object of the present invention to provide a motor vehicle with a front loading space in which the loading and unloading convenience is further improved compared to the prior art.

To solve this problem, a motor vehicle with the features of claim 1 is proposed. Advantageous configurations result from the subclaims and the following description. The motor vehicle has a vehicle stem, also referred to as a front end, with everything in the forward direction of travel in front of an end wall separating the stem from a passenger compartment being attributed to the vehicle stem. A load space is provided in the front end of the vehicle, for storing units, for example

Components of a vehicle drive or other components can be used. The loading space can be covered by means of a front hood which is movable between a closed position and an open position and is usually pivotably mounted. Arranged in the loading space is a load receptacle which can be adjusted between a basic position and a loading position and is generally referred to as a trunk, in which, for example, luggage or other, in particular movable, objects can be accommodated.

The motor vehicle is characterized in that the load in the

Loading position is inclined relative to its basic position to the outside of the vehicle. By practically accommodating, the loading of goods to a person standing in front of the motor vehicle offers itself quasi directly, who can then load or unload objects in a very short way. This is particularly advantageous in the case of tall vehicles, so-called SUVs, because here the load to be introduced into the load receptacle is via a radiator grille and

If necessary, a so-called “soft nose” must be lifted over a panel between the radiator and the front hood.

In a preferred embodiment, the load receptacle is on the circumference

closed room, which is closed at the bottom by a floor.

If necessary, the load receptacle can be closed by means of a cover, preferably in a sealing manner. It should be noted that the bottom of the

Load receptacle in the loading position with an imaginary horizontal plane spanning the vehicle transverse (y direction) and vehicle longitudinal direction (x direction) encloses a larger angle than in its basic position, in which the floor of the load receptacle is preferably arranged parallel to the horizontal plane. This means that the load is inclined towards the loader in the loading position.

According to a development of the invention it is provided that the person

facing, preferably front wall of the load receptacle is designed to be foldable and at least in the loading position of the load receptacle can be folded forward towards the person loading it. Thus, the interior is the inclined load receptacle even more accessible, since the objects no longer have to be lifted over this wall of the load receptacle. According to a further development, it is provided that the foldable side or

Front wall of the cargo receptacle in its folded position extends over a loading edge of the motor vehicle and thereby protects it from damage. At the same time, covering this area reduces the risk of contamination for the operator.

An exemplary embodiment of the motor vehicle is particularly preferred in which the load receptacle in the loading position — viewed in the forward direction of travel of the motor vehicle — is arranged inclined forward. This makes loading and unloading particularly easy and convenient for a person standing in front of the vehicle. In this position, the otherwise upward sloping front hood, which is arranged in the open position and protects the load receptacle from rain and snow during the loading process, is very clearly visible.

In a particularly advantageous embodiment, the load receptacle can be pivoted about an axis running in the transverse direction of the vehicle. According to an advantageous embodiment variant, the axle is stationary relative to the vehicle stem. This allows a pure swiveling movement of the load receptacle around this axis

Realize the direction of view in the vehicle's transverse direction clockwise and counterclockwise. Not only is the load receptacle inclined forward in the direction of travel, but the floor of the load receptacle is also raised, at least in its area facing the passenger compartment. According to another embodiment variant, the load is picked up by means of a

Coupling gear mounted, which is not only possible to raise and lower the entire load receptacle, but also inclined in the desired manner, that is, can be inclined towards a user. In addition, there is also a translational movement of the load receptacle superimposed on these movements

Longitudinal direction of the vehicle is possible, so that the load can be moved as a whole towards the person standing in front of the vehicle.

To shift the load between the basic position and the

Loading position, a separate drive can be provided so that the

Load pick-up is adjustable independently of the front hood. According to another advantageous embodiment, the load receptacle is coupled to the front hood, so that when the front hood is opened, the load receptacle is automatically carried along into the loading position. This is particularly convenient for a user. In addition, both the front cover and the load receptacle can be moved here by means of a single drive, which can have cost advantages.

To achieve the object, a motor vehicle with the features of claim 2 is also proposed, in which the load receptacle is pivotally coupled to the front hood, even then or also in the embodiment of the motor vehicle in which the load receptacle is only adjustable in height and - unlike in the variant according to claim 1 provided - can not be inclined. Further advantageous embodiments result from the subclaims.

Further advantages, features and details of the invention result from the following description of advantageous exemplary embodiments and from the drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A motor vehicle 1 according to the invention is shown in detail in FIGS. 1 and 2, which comprises a front loading space 2 which has a loading space opening 3. A front hood 4 is pivotally mounted on the motor vehicle 1, that is to say on its body, the front hood 4 being pivotable between a closed position 5, which is shown in FIG. 1, and at least one open position 6, which is shown in FIG. 2. The front hood 4 closes in the closed position 5

Loading space opening 3 and releases the loading space opening 3 in the open position 6, so that it is accessible from outside the motor vehicle 1 and objects can be accommodated or removed therein.

A cargo receptacle 7 is arranged in the loading space 2 and is designed in the form of a storage box, tub or tray. The cargo receptacle 7 is here closed on the circumference and for this purpose has a front wall 9 and a rear wall 11, viewed in the forward direction of travel, which are connected by means of side walls (not shown). The load receptacle 7 is downwards by means of a bottom 13 closed. In the area of the rear wall 11 there is provided a cover 17, which can be pivoted about an axis 15 and is shown with a broken line, by means of which the cover 17

Load receptacle 7 can be sealed. The cover 17 is optional, that is to say the load receptacle 7 can also be designed without a cover. A

In this case, closing, and possibly also sealingly closing, the cargo receptacle can also be carried out by means of the front hood, which for this purpose may have a corresponding sealing contour, which is brought into sealing contact with sealing surfaces of the cargo receptacle in the closed position of the front hood.

In the embodiment shown in FIGS. 1 and 2, the cargo receptacle 7 is connected to the front hood 4 via a coupling element 19, which is preferably resistant to pressure and tension, in particular designed as a pendulum support,

Loading position, which is shown in Figure 2, moves, the loading position being higher compared to the basic position with respect to the motor vehicle 1. Furthermore, the load receptacle 7 is pivoted and / or rotated in the loading position in comparison to the basic position, specifically in the direction of a person in front of the motor vehicle. This means that the base 13 is clearly inclined relative to its starting position in the basic position of the load receptacle. The tilted, inclined arrangement of the load receptacle in the direction of travel makes loading and unloading much easier and more convenient than if it remained in its basic position. It should be noted that in the exemplary embodiment according to FIGS. 1 and 2, the load receptacle can be tilted about an axis which is stationary with respect to the body and which runs through the joint 27 in the transverse direction of the vehicle, i.e. perpendicular to the image plane of FIGS. 1 and 2, this here due to the coupling with the bonnet positively controlled when it is moved between the closing and

The first link element 29 and the second link element 33 can each be designed as a pendulum support and here form a four-bar mechanism by means of which the load receptacle 7 can be moved from its basic position into the loading position in a combined lifting and swiveling movement.

The coupling element 19, which can be designed as a pendulum support, is connected to the front hood 4 via the joint 23 and via the joint 21, which is in the region of the

Rear wall 11 is pivotally coupled to the load receptacle 7.

If the front hood 4 is moved from the closed position 5 to the open position 6, the cargo receptacle 7 becomes one by coupling with the front hood 4 Basic position, which is shown in FIG. 3, is raised to a loading position, which is shown in FIG. 4, the loading position being higher than the basic position with respect to the motor vehicle 1. Furthermore, the load receptacle 7 in the

Loading position pivoted and / or rotated compared to the basic position. The loading position of the load receptacle 7 is compared to

Basic position shifted in the front direction of the motor vehicle. Here too is the

Load receptacle 7 is arranged inclined towards a person in front of the motor vehicle.

FIGS. 5 and 6 show a detail of a motor vehicle 1 according to the invention, which comprises a load space 2 on the front, in which a height-adjustable load receptacle 7 is arranged, which can be pivoted with the front hood 4

Coupling gear 39 is coupled. The coupling gear 39 comprises coupling elements 41, 43 and 45.

The coupling elements 41, 43 and 45 form a three-joint coupling element which is pivotally coupled to the motor vehicle 1 with a joint 47. The three-articulated coupling member is pivotally coupled to the cargo receptacle 7 via a joint 49 and pivotably coupled to the coupling element 19 via a joint 51, the coupling element 19 being pivotably coupled at one end to the front hood 4 via the joint 23.

FIG. 7 shows a further detail in a schematic representation

Embodiment of motor vehicle 1 in which a load receptacle 7

is provided, which differs from the exemplary embodiment according to FIGS. 1 and 2 in particular in that the cover 17 is integrated in the coupling element 19, which is preferably designed as a tension / compression strut and which couples the load receptacle 7 to the front hood, or the coupling element 19 as Lid 17 is designed by means of which the interior is sealed when the front hood is closed and the cargo receptacle 7 is arranged in the basic position. The coupled opening of the cover 17 with the front hood 4 allows the cargo receptacle to be opened comfortably. FIG. 8 shows a further detail in a schematic illustration

Embodiment of motor vehicle 1 in which a load receptacle 7

is provided, which differs from the exemplary embodiment according to FIGS. 3 and 4 in particular in that the lid 17 of the cargo receptacle 7 is opened and closed by means of a four-bar linkage. The four-bar linkage here comprises the link element 10, which is articulated at one end to the cargo receptacle 7 via a joint 27 which is arranged in a fixed position / position with respect to the body and at the other end. Furthermore, the link element 33 is provided, which is firmly connected at one end to the body via the joint 35 and at the other end is connected directly via a joint 53 to a coupling element 55 fixedly attached to the cover 17.

The joint 53 is located at a distance from the axis 15 about which the cover 17 can be pivoted on the load receptacle 7.

In Figure 8, the coupling of the cargo receptacle 7 with the front cover 4 is off

Not shown for reasons of clarity, but may be the same as or similar to the exemplary embodiments of the invention described above. It is important that here too, when the front hood 4 is shifted, the load receptacle 7 is shifted from its lowered basic position into a raised loading position that is inclined forward toward the front of the vehicle. It is important in this exemplary embodiment that the link element 33 and the coupling element 19, not shown, for connecting the load receptacle 7 to the front hood 4 in an end position (open position of the

Front hood) lie in a stretched position, that is to say they are in alignment or - viewed in the direction of gravity - are essentially arranged one above the other. In this case, these can optionally also be locked together so that pivoting back of the cargo receptacle 7 and thus also the front cover 4 can be avoided by the weight of the cargo in the cargo receptacle 7.

It is common to all of the exemplary embodiments that the opening of the front hood 4 and the lifting and

Can automatically tilt the load receptacle 7.

All embodiments of the motor vehicle with cargo receptacle 7 and cover 17 have in common that the front hood 4 has no sealing surfaces in the case of a

Pedestrian impact must have critical head impact areas. The cargo receptacle 7 is sealed by the cover 17, which, when the bonnet is closed and the cargo receptacle 7 is lowered in the basic position, is removed from the bonnet is spaced. Furthermore, the cover 17 also does not require a separate locking device, since this is held down by holding down the front hood by means of a corresponding one

Front hood lock is secured in the basic position on the load receptacle 7.
