Description

The present invention relates to a front flap arrangement for a motor vehicle with the features of the preamble of patent claim 1 and to a motor vehicle with such a front flap arrangement.

Front flap arrangements for covering an engine compartment and/or a luggage compartment arranged in a front area of a motor vehicle are known in various configurations from the prior art.

The DE 10 2021 109 277 A1 describes a motor vehicle with a closure plate for covering an engine compartment of the motor vehicle. The closure plate is mounted centrally on the motor vehicle in the transverse direction of the motor vehicle about a pivot axis extending in the longitudinal direction of the motor vehicle. This means that either an engine compartment located to the left of the pivot axis in the transverse direction of the vehicle or an engine compartment located to the right of the pivot axis in the transverse direction of the vehicle is accessible.

Based on that in the DE 10 2021 109 277 A1 described motor vehicle, it is the object of the present invention to provide a front flap arrangement for covering an engine compartment of the motor vehicle and / or a luggage compartment arranged in a front area of the motor vehicle, which ensures simultaneous accessibility of an entire engine compartment and / or a luggage compartment arranged in a front area of a motor vehicle enabled. A further object of the present invention is to provide a motor vehicle with such a front flap arrangement.

This object is achieved according to the invention by the front flap arrangement with the features of patent claim 1 and the motor vehicle with the features of patent claim 11.

According to the invention, a front flap arrangement for a motor vehicle, in particular for covering an engine compartment of the motor vehicle and/or a luggage compartment arranged in a front region of the motor vehicle, is provided, which comprises at least two covers. The two covers can be mounted on the motor vehicle so that they can pivot about a pivot axis extending in the longitudinal direction of the front flap arrangement between a closed position and an open position, in particular via intermediate positions. In the closed position, the engine compartment or the luggage compartment arranged in the front area of the motor vehicle, in particular at the top in the vertical direction of the motor vehicle, is covered by the front flap arrangement. If the covers are in the open position, the engine compartment or the luggage compartment arranged in the front area of the motor vehicle, in particular at the top in the vertical direction of the motor vehicle, is open and therefore accessible. If only one of the covers is in the open position, part of the engine compartment or the luggage compartment arranged in the front area of the motor vehicle, in particular the engine compartment or luggage compartment arranged below the cover in question, in particular upwards in the vertical direction of the motor vehicle, is open. The front flap arrangement further comprises a water drainage channel, which, when the covers are in the closed position, is covered by the covers, in particular in the front flap arrangement vertical direction at the top. If one of the covers is in the closed position, the water drainage channel is partially covered, especially in the vertical direction of the front flap arrangement.

The core idea of the invention is therefore to provide two covers, each of which can be pivoted independently of one another about a pivot axis extending in the longitudinal direction of the front flap arrangement on the motor vehicle. An engine compartment and/or luggage compartment arranged to the left of the pivot axis and an engine compartment and/or luggage compartment arranged to the right of the pivot axis are therefore accessible at the same time. The water drainage channel also makes it possible to prevent unwanted entry of deposits on the covers, in particular liquids, into the engine compartment or the luggage compartment.

The water drainage channel is arranged centrally in the front flap arrangement transverse direction, for example.

A position of the longitudinal center plane of the water drainage channel can correspond to a center point between the two pivot axes of the covers in the transverse direction of the front flap arrangement.

The water drainage channel is provided in the vertical direction of the front flap arrangement, for example below the covers.

When they are in the open position, the covers can be partially arranged in a cavity enclosed by the water drainage channel.

In an exemplary embodiment of the front flap arrangement according to the invention, the covers each have at least one hinge fixed to the body, in particular two hinges fixed to the body, ie hinges which are rigid with connected to a body of the motor vehicle, can be stored on the body.

The hinges are, for example, fixed to the body directly or via a support element.

For example, the hinges are fixed to a front region of one of the covers in the longitudinal direction of the front flap arrangement and to a rear region of one of the covers in the longitudinal direction of the front flap arrangement.

In a preferred embodiment of the front flap arrangement according to the invention, the pivot axes of the covers in the vertical direction of the front flap arrangement are aligned with lateral ends of the water drainage channel. The pivot axes therefore have the same position in the front flap arrangement transverse direction as the side ends of the hydropower canal.

Alternatively, the pivot axes of the covers can be arranged laterally next to the water drainage channel in the transverse direction of the front flap arrangement.

In an exemplary embodiment, the front flap arrangement according to the invention comprises at least two locking elements. The covers can be secured in the closed position, in particular on the body of the motor vehicle, by means of the at least two locking elements. In particular, a first of the covers can be secured in the closed position by means of a first of the locking elements and the second cover can be secured in the closed position by means of the second locking element.

The locking elements are adjustable, for example, between a locking position and a release position. If the locking elements are in the release position, the covers can be pivoted from the closed position into the open position.

For example, the two locking elements are arranged on the cover in question in a central region in the front flap arrangement's longitudinal direction and an outer region in the front flap arrangement's transverse direction of the cover in question.

In an exemplary embodiment, the front flap arrangement according to the invention comprises four locking elements, i.e. two locking elements per cover.

The locking elements are arranged, for example, in an outer region in the front flap arrangement transverse direction and in a front or a rear region of the relevant cover in the front flap arrangement longitudinal direction on the relevant cover.

In a preferred embodiment, the front flap arrangement according to the invention comprises at least two bearing arrangements. The covers can be stored in the closed position by means of the at least two bearing arrangements.

The bearing arrangements can each include a securing element. The securing elements can secure the covers in the closed position if a force that exceeds a predefined value acts on the covers in the upward direction of the front flap assembly. If a force acting upward on the covers in the front flap assembly vertical direction is below the predefined value, the securing elements release the covers. The covers can therefore be pivoted into the open position. This can ensure that the covers do not open or even bend over, even at high travel speeds, especially in the area of the bearing arrangements.

For example, the bearing arrangements are each arranged on the cover in question in an outer region in the front flap arrangement's transverse direction, in a front region in the front flap arrangement's longitudinal direction and in a rear region of the relevant cover in the front flap arrangement's longitudinal direction.

The bearing arrangements can also be arranged on the cover in question in an outer region in the transverse direction of the front flap arrangement, in a front region in the longitudinal direction of the front flap arrangement or in a rear region of the covers in question in the longitudinal direction of the front flap arrangement, and the locking elements can be arranged on the cover in question in a front flap arrangement - Transverse direction outer region, in a rear region in the front flap arrangement longitudinal direction or in a front region in the front flap arrangement longitudinal direction of the relevant cover, i.e. in the front flap arrangement longitudinal direction on one of the relevant bearing arrangement in the front flap arrangement longitudinal direction opposite sides of the relevant cover.

In a preferred embodiment, the front flap arrangement according to the invention comprises at least two lifting devices, i.e. one lifting device per cover. By means of the Lifting devices allow the covers to be displaced upwards relative to the water drainage channel in the vertical direction of the front flap arrangement, in particular to be lifted.

The lifting devices are, for example, each arranged between a relevant locking element and a relevant cover.

The lifting devices can also be arranged between a relevant locking element and the body of the motor vehicle.

The lifting devices can be arranged at a distance from the connecting elements.

The lifting devices can each be arranged together with a relevant locking element on a connection plate.

The connection plate, for example, is fixed to the body.

By means of the lifting devices, the covers can be displaced upwards, for example at a front end in the longitudinal direction of the front flap arrangement, relative to the water drainage channel in the vertical direction of the front flap arrangement.

In a central region in the front flap arrangement's longitudinal direction, the cover can be displaced upwards in the front flap arrangement's vertical direction by means of the lifting devices, for example relative to the water drainage channel.

At the rear end in the front flap arrangement's longitudinal direction, the covers can be displaced upwards in the front flap arrangement's vertical direction by means of the lifting devices, for example relative to the water drainage channel.

The lifting devices are, for example, part of the locking elements.

In a preferred embodiment, the front flap arrangement according to the invention comprises at least one seal. The seal is arranged between the two covers in such a way that it connects the two covers together in a material-tight manner when the covers are in the closed position. This ensures that no deposits on the covers get into the engine compartment or luggage compartment when the covers are in the closed position.

The seal is arranged, for example, at a first end of a first one of the covers, which faces the second cover.

The front door assembly may include two seals disposed at a first end of a first one of the covers facing the second cover and a first end of the second cover facing the first cover.

In an exemplary embodiment, the front flap arrangement according to the invention comprises two water drain channel seals which connect the covers to the water channel in a liquid-tight manner. This prevents unwanted penetration of deposits, in particular liquid, into areas that laterally adjoin the water drainage channel.

The water drain channel seals can extend in the longitudinal direction of the front flap assembly along the entire water drain channel.

The water drain channel seals are, for example, each attached to a respective one of the covers and, when the covers are in the closed position, close to the water channel in a liquid-tight manner.

The water drainage channel is made of plastic, for example.

The water drainage channel can have a U-shaped profile in the longitudinal direction of the front flap arrangement when viewed from the front.

The two covers can each include at least one reinforcement.

The reinforcement extends, for example, in the longitudinal direction of the front flap arrangement, in particular over the entire length of the cover in question, and is arranged, for example, in a middle region of the front flap arrangement in the transverse direction of the front flap arrangement, i.e. an inner region of the cover in question.

The reinforcements can be arranged in a front and/or rear region of the covers in the longitudinal direction of the front flap arrangement and extend in the transverse direction of the front flap arrangement, in particular over the entire width of the covers.

In a preferred embodiment of the front flap arrangement according to the invention, the covers and/or the water drain box nal at least one predetermined kink point and/or at least one predetermined breaking point.

The predetermined breaking point(s) and/or the predetermined breaking point(s) can extend in the front flap arrangement transverse direction and/or front flap arrangement vertical direction.

The invention further relates to a motor vehicle comprising a front flap arrangement described above.

The front flap arrangement longitudinal direction, the front flap arrangement transverse direction and the front flap arrangement vertical direction correspond, for example, to a motor vehicle longitudinal direction, a motor vehicle transverse direction and a motor vehicle vertical direction, respectively.

The invention is explained in more detail below using an exemplary embodiment shown in the drawing. It shows:

• 1 a perspective view of a motor vehicle according to the invention with a front lid assembly comprising covers that are in an open position;
• 2 a perspective view of the front flap arrangement 1 , additionally comprising two locking elements, the covers being in a closed position and a representation of a water drain channel has been omitted;
• 3 a portion of a section along line III - III in 2 ;
• 4 a top view of a portion of the motor vehicle according to the invention 1 , additionally comprising two locking elements and four bearing assemblies, the covers being shown transparently and being in the closed position; and
• 5 a top view of a portion of a further motor vehicle according to the invention with a front flap arrangement with four locking elements and two covers that are in a closed position.

In the 1 until 4 is a portion of a first motor vehicle 4 according to the invention, comprising a front flap arrangement 2 shown. The front flap arrangement 2 is arranged in the longitudinal direction x of the motor vehicle in front of a partition 28, which separates a luggage compartment 32 of the motor vehicle 4, which is arranged in a front region of the motor vehicle 4 in the longitudinal direction x, from a passenger compartment of the motor vehicle 4.

The front flap arrangement 2 includes a first cover 6 and a second cover 8, which are designed mirror-symmetrically to a motor vehicle longitudinal center plane 36.

The first cover 6 and the second cover 8 are each mounted on a body 18 of the motor vehicle 4 so that they can pivot about a pivot axis 10 via hinges 16 fixed to the body. The covers 6 and 8 are therefore each between one in 1 shown open position and one in the 2 until 4 Adjustable closed position shown.

In the open position, the luggage compartment 32 is released upwards in the vertical direction z of the motor vehicle, so that objects can be inserted into and removed from the luggage compartment 32. If the covers 6 and 8 are in the closed position, the luggage compartment 32 is bounded at the top by the covers 6 and 8 in the vertical direction z of the motor vehicle.

In order to ensure that the luggage compartment 32 is protected from environmental influences in the closed position of the covers 6 and 8 and to improve the aerodynamics of the front lid arrangement 2, the covers 6 and 8 each comprise at their inner ends in the transverse direction y of the motor vehicle, i.e. at their the end facing the other cover 8 or 6, a seal 26. The seals 26 extend over the entire length of the covers 6 and 8.

A water drainage channel 12 is arranged between the hinges 16 fixed to the body, which extends in the longitudinal direction x of the motor vehicle and has a U-shaped profile.

How out 3 As can be seen, the covers 6 and 8 are connected to the water drain channel 12 via water drain channel seals 34.

If the covers 6 and 8 or if one of the covers 6 and 8 is moved from the closed position to the open position, deposits present on the covers 6 and 8 or the cover 6 or 8 in question, in particular liquids and/or solids, get into the water drainage channel 12, via which these can be drained in a defined manner.

The body-mounted hinges 16 are each connected to a drive unit 30. By means of the drive unit 30, the covers 6 and 8 can be individually, automatically adjusted between the closed position and the open position.

It is also conceivable to open and/or close the covers 6 and 8 manually.

The motor vehicle 4 according to the invention further comprises two locking elements 24, ie a lifting device 24 per cover 6 or 8. By means of the lifting devices 24, the covers 6 and 8 are relative to the water drainage channel 12 and therefore relative to the body 18 of the motor vehicle 4 in the vertical direction of the motor vehicle z can be moved upwards.

To secure the covers 6 and 8 in the closed position, the covers 6 and 8 are each provided with a locking element 20 (see 2 ). The locking elements 20 secure the covers 6 and 8 in the closed position of the covers 6 and 8 on the body 18.

The locking elements 20 are arranged on the covers 6 and 8 in a central area in the vehicle's longitudinal direction and outer area in the vehicle's transverse direction y of the relevant cover 6 and 8, respectively.

Furthermore, a bearing arrangement 22 is provided in the vehicle transverse direction y on the outside at a front end in the vehicle longitudinal direction x and at a rear end in the vehicle longitudinal direction x of the covers 6 and 8.

The bearing arrangements 22 each include a securing element. The securing elements are designed in such a way that they secure the relevant cover 6 or 8 in the closed position when a force which exceeds a predefined value acts on the relevant cover 6 or 8 in the front flap arrangement vertical direction z. If a force acting upwards on the relevant covers 6 or 8 in the front flap arrangement vertical direction z is below the predefined value, the securing element releases the covers 6 or 8, so that the relevant cover 6 or 8 is unlocked when the relevant locking element is unlocked 20 can be pivoted into the open position.

In 5 another motor vehicle 38 is shown according to the invention. The further motor vehicle 38 according to the invention essentially corresponds to that in the 1 until 4 Motor vehicle 4 shown. Therefore, only the distinguishing features will be explained below. The above statements regarding the motor vehicle 4 apply accordingly to all other features.

While that's in the 1 until 4 Motor vehicle 4 shown has two locking elements 20 and four bearing arrangements 22, the further motor vehicle 38 instead comprises four locking elements 20, ie two locking elements 20 per cover 6 or 8.

If the covers 6 and 8 are in the closed position, the locking elements 20 are in an outer region of the covers 6 and 8 in the vehicle transverse direction y, in the vehicle longitudinal direction x at a front end region and at a rear end region of the relevant cover 6 or 8 arranged. By means of the locking elements 20, the covers 6 and 8 can be stored and secured to the body of the other motor vehicle 38.
