This patent application claims the benefit of German application No. 10 2020 122 965.8, filed Sep. 2, 2020, the teachings and disclosure of which are hereby incorporated in their entirety by reference thereto.
The invention relates to a mounting system for a load carrier or a trailer coupling, comprising at least one mounting receptacle, which is mountable on a rear section of a motor vehicle body.
Such mounting systems are known from the prior art.
These usually use a cross-member, which can be mounted on the rear section, carries the mounting receptacle and on which the load carrier or the trailer coupling are then fixable.
These solutions are known from the prior art, but lead to a significant increase of the vehicle weight, in particular if a load carrier or trailer coupling is not being used.
These solutions are then less suitable, in particular if weight-reduced solutions are required, for example also in the case of electric cars.
The object of the invention is therefore to create a mounting system of the kind described at the outset which allows a very high weight saving, in particular in the case that a load carrier or a trailer coupling is not being used.
In a mounting system of the kind described at the outset, this object is achieved in accordance with the invention in that the mounting system has a set of two mounting receptacles, which is configured such that each of the mounting receptacles in the mounted state is connected to the motor vehicle body by means of a mounting region for a rear-side impact or crash element provided on the motor vehicle body.
This solution has the great advantage that a simple attachment to the rear section of the motor vehicle can be achieved by means of the mounting regions for the rear-side impact or crash element and in particular is possible together therewith.
It is particularly favorable here if the impact or crash element has a carrier that is deformable in the event of an impact or crash and that is connected by means of mounting attachments to the mounting regions of the motor vehicle body.
A carrier of this kind has the advantage that it can deform, at least within limits, independently of the rear section of the motor vehicle and can thus absorb impact and/or crash energy.
The mounting receptacles are particularly advantageously connected to the mounting region in each case by means of a mounting carrier, by means of which the mounting receptacle is connectable or, in the mounted state, is connected to the corresponding mounting region.
Here, the mounting receptacles are preferably arranged next to the mounting attachments of the impact or crash element by the mounting carrier, so that there is thus no need for any structural changes to the impact or crash element with its mounting attachments, and instead the mounting receptacles can in turn be made accessible as a result of their arrangement next to the mounting attachments of the impact or crash element.
It is particularly favorable if the mounting receptacles are arranged, by means of the mounting carrier, below the mounting attachments of the impact or crash element in the direction of the force of gravity.
In order to make the mounting carrier on the one hand as simple as possible and on the other hand as stable as possible, it is preferably provided that the mounting carrier is fixed between a mounting attachment of the impact or crash element and the corresponding mounting region of the motor vehicle body for connection to the mounting regions of the motor vehicle body, in particular is clamped between the corresponding mounting attachment and the corresponding mounting region, and is fixed on the mounting region together with the mounting attachment by the connection of the corresponding mounting attachment to the mounting region, for example by means of screws.
A wide range of different possibilities are conceivable in respect of the configuration of the mounting carrier.
An advantageous solution provides that the mounting carrier has a central body which is stabilized by at least one reinforcement.
Here, it is preferably provided that the central body has a support region, which is fixable between the mounting region and the corresponding mounting attachment.
To save weight, the central body can be provided with one or more recesses.
A central body of this kind should be as flat as possible so as not to negatively influence the connection between the mounting region and the mounting attachment.
For this reason, the at least one reinforcement runs outside the support region.
It is furthermore preferably provided that the central body has a holding region, which carries the mounting receptacle.
In order to also configure a holding region of this kind as simply as possible, it is also provided that the at least one reinforcement runs outside the holding region.
It is also possible, however, to connect the at least one reinforcement to the mounting receptacle.
A solution in which the support region and the holding region are connected to one another in a rigid manner by the at least one reinforcement is particularly favorable.
No further details have yet been provided in respect of the configuration and use of the mounting receptacles.
It is particularly favorable if each of the mounting receptacles is connectable to a mounting element for mounting a load carrier or a trailer coupling.
A mounting element of this kind can be connected to the mounting receptacles in a very many ways.
A particularly simple and in particular weight-saving solution provides that the mounting receptacles are sleeve-like, so that the mounting elements are insertable into them or attachable to them.
It is particularly favorable if mounting elements can be inserted into the mounting receptacles and can be fixed therein, which mounting elements are in turn provided in particular with load receptacles, which allow a connection to a load carrier or a trailer coupling.
In order to provide a secure mounting of each mounting element on its corresponding mounting receptacle, it is preferably provided that each mounting element has a guide body, by means of which the mounting element is insertable in an insertion direction into the mounting receptacle or placeable thereon and is fixable thereto against transverse movements and/or rotations about the insertion direction.
It is also preferably provided that, by means of stops, each mounting element is positionable in a defined manner in the insertion direction relative to the corresponding mounting receptacle.
In order to be able to fix the mounting element in the mounting receptacle, each mounting element is preferably provided with a securing unit, in which the mounting element is fixable, in the position inserted into the mounting receptacle, against a movement opposite the insertion direction.
An advantageous solution provides that the securing unit has a securing body, which is configured to be brought into engagement with a securing receptacle, for example a recess, of the mounting receptacle.
In addition, it is preferably provided that a carrier base of a load carrier or of a trailer coupling is fixable in the load receptacle of each mounting element.
This means that the load receptacle itself in turn merely represents a receptacle for a carrier base of a load carrier or of the trailer coupling.
In principle, the mounting elements can be connected, for example fixedly connected, to the carrier base of the load carrier or of the trailer coupling.
It is also possible, however, to make the load receptacles such that the carrier base of the load carrier or of the trailer coupling, once the mounting elements have been inserted into the mounting receptacles, is fixable in a force-locking and/or positive-locking manner or, in the operating state, is fixed in a force-locking and/or positive-locking manner.
An advantageous and in particular easily realized solution provides that there are associated with each load receptacle clamping elements, by means of which the carrier base is fixable in the corresponding load receptacle, as applicable in a force-locking addition to a positive engagement.
This is possible, for example, since the clamping elements act directly on the carrier base.
It is also conceivable, however, that the clamping elements deform the load receptacle itself in such a way that the carrier base is clampable by the load receptacle.
An advantageous configuration of a load receptacle of this kind provides that this is U-shaped, for example in order to receive the carrier base.
In order to also ensure that the securing body, when the load carrier is mounted or when the trailer coupling is mounted, remains engaged with the securing receptacle in the mounting receptacle, it is preferably provided that the securing body is blocked by a blocking element against a movement out from the securing receptacle, when the load carrier or the trailer coupling is held in the respective load receptacle, in particular is held by means of the carrier base.
Another advantageous solution provides that the set of two mounting receptacles is held on the impact or crash element, that is to say is directly connected to the impact or crash element. This can be an indirect, releasable connection, for example by means of a mounting carrier, or a direct connection, for example by joining.
A preferred solution in this case provides that the mounting receptacles are connected to the carrier of the impact or crash element. This can be an indirect, releasable connection, for example by means of a mounting carrier, or a direct connection, for example by joining.
Here, the mounting receptacles can be arranged for example on the carrier in continuation of the mounting attachments, so that in particular the mounting attachments can be configured such that they likewise also form the mounting receptacles.
Another advantageous solution provides that the mounting receptacles are arranged offset relative to the mounting attachments of the impact or crash element.
In principle, the mounting receptacles could be arranged on the carrier such that they are held releasably thereon, for example by screwing.
Another advantageous solution provides that the mounting receptacles are connected non-releasably to the carrier of the impact or crash element, that is to say for example are welded thereto.

Further features and advantages of the invention are the subject of the following description and also the representation of some exemplary embodiments in the drawings.
An exemplary embodiment, shown in
Each mounting region 26 of the rear section 14 is formed for example by one of two side members 28 extending in the vehicle longitudinal direction 18 on opposite longitudinal sides of the motor vehicle body 12, which side members for example each also carry a termination plate 32, wherein the termination plate 32, with its side facing the mounting attachment 24, forms the mounting region 26 on the rear section 14.
Each of the mounting attachments 24 preferably comprises a flange plate 34 and a support arm 36, which extends from the flange plate to the carrier 22 and holds the carrier 22 at a spacing from the rear section 14 so that the carrier 22, in the event of a rear-side impact on the motor vehicle body 12, can deform at least initially independently thereof.
The impact and crash element 16 is also preferably covered by a bumper unit 38, which is held on the rear section 14 so as to be visible and is provided fundamentally for the visual design of the rear section, but for example in the event of a rear impact on the motor vehicle 10 has an insignificant influence on the absorption of forces.
In order to be able to mount a load carrier or a trailer coupling on a motor vehicle 10 of this kind, in particular the motor vehicle body 12 thereof on its rear section 14, a set 40 of mounting receptacles 42 is provided for releasable fixing of a load carrier or of a trailer coupling, which mounting receptacles for example each have a receiving sleeve 44, which are used to receive mounting elements described hereinafter in detail.
For example, the receiving sleeves 44 are formed here as sleeve bodies that are rectangular in cross section.
To connect these mounting receptacles 42 to the motor vehicle body 12, each of these mounting receptacles 42 is fixed to a mounting carrier 46, which, as shown in
The mounting carrier 46 is preferably formed not exclusively as a flat plate, but, as shown in
Instead of turned-up edges 54, it is also possible here to provide beads or folds, in particular laterally of the central body 52.
The central body 52 is formed here in particular such that it forms a central support region 56, on which the mounting attachments 24 of the impact or crash element 16, in particular with the flange plates 34, are supportable over the entire surface, which central support region can thus be clamped between the corresponding mounting attachment 24 and the corresponding mounting region 26.
The support region 56 furthermore also has openings 58, which are arranged congruently with corresponding openings 62 in the flange plates 34 and thus allow the corresponding flange plate 34 to be screwed to the central body 52 of the mounting carrier 46 and the mounting region 26.
Furthermore, in the solution according to the invention, the mounting receptacles 42 are welded by means of an end face 64 to a holding region 66 of the central body 52, wherein the reinforcements 54 extend both along the support region 56 and the holding region 66 in order to thus fix the holding region 66 relative to the support region 56 in a bend-proof manner, in particular rigidly.
As shown in
In particular, the guide body 84 comprises a C-shaped main body 88 and a support body 92 inserted into the main body 88, so that the main body 88 with its middle limb 94 on the one hand and the support body 92 on the other hand forms a lateral guide for the mounting element 82 and with its two side limbs 96 and 98 secures the mounting element 82 in the receiving sleeve 44 of the mounting receptacle 42 against movements parallel to a vertical direction.
The guide body 84 is furthermore also provided with stops 102 protruding beyond the guide body on both sides, which stops delimit the insertion of the guide body 84 into the receiving space 68 of the corresponding mounting receptacle 42, in particular of the corresponding receiving sleeve 44, by abutting against the end face 104 furthest away from the mounting carrier 46.
To fix each mounting element 82 in the corresponding mounting receptacle 42, the mounting element 82 in question is provided with a securing unit 112, which has a securing body, for example a securing hook 114, which cooperates with a securing receptacle 116, for example formed in the manner of an aperture in the mounting receptacle 42, in particular the receiving sleeve 44 thereof, in order to be able to secure the mounting element 82, in its position inserted into the corresponding mounting receptacle 42, against a movement opposite the insertion direction.
Here, the securing body 114 is acted on by means of a spring element 118 such that the securing body 114, when the mounting element 82 is inserted into the mounting receptacle 42, aims to come into engagement with the securing receptacle 116.
In the simplest case, the securing body 114 is mounted rotatably about a pin forming the stops 102 and is acted on by the spring element 118 in the direction of a pivoting movement into the position engaging in the securing receptacle 116.
As can be seen in particular in
In addition, as shown in
In a second exemplary embodiment, the carrier base 132 is not the carrier base of a load support 130, but of a trailer coupling 160, and carries a ball neck 162 with a coupling ball 164, to which a trailer can be coupled in the known manner (
In a third exemplary embodiment, shown in
Furthermore, the mounting receptacles 42 are formed similarly to the first exemplary embodiment, so that, as shown in
In a fourth exemplary embodiment, shown in
In this exemplary embodiment as well, in particular the receiving sleeves 44 are formed similarly as in the preceding exemplary embodiments, so that the same mounting elements 82 as in the preceding exemplary embodiments can be inserted into these receiving sleeves 44, which mounting elements are provided with the load receptacles 122 similarly as in the preceding exemplary embodiments.
In the fourth exemplary embodiment as well, the carrier base 132 of the load carrier 130 or of the trailer coupling 160 is thus insertable into the load receptacles 122 and fixable therein.
