Abstract

Instrument carrier of a motor vehicle (2), wherein the instrument carrier (12) has at least one lying in a transverse direction to the direction of travel in an end region (14.1, 14.2) cavity (16) having an insertion contour forming inner surface (14.5), wherein in the cavity (16) at least one accumulator (20.1, 20.2, 20.3) is arranged. Furthermore, a corresponding motor vehicle (2) is described.

Description

Described are an instrument carrier of a motor vehicle and a corresponding motor vehicle.

Modern motor vehicles have a large number of components and units. In particular, the number of electrical and electronic components has risen sharply due to the increasing complexity in the past. Many motor vehicles are equipped with a considerably larger number of control units than previous motor vehicles. The control units are required to implement a variety of newer functions and assistance systems. In the effort of space optimization, this increase in control units is a challenge.

The DE 10 2004 056 102 A1 discloses a component comprising a shell-shaped base support and at least one core element, wherein the base support has at least one closing seam and is connected to the core element via at least one tolerance-compensating intermediate layer. In addition, electrical lines, conductor tracks, fiber optic cables, sensors, strain gauges and / or electronic chips can be provided, which are introduced in a cavity formed between the core element and the base support. Basic carrier and core element form a stable component in lightweight construction. The component can be used, for example, as an instrument panel carrier.

A disadvantage of this component is that only little space can be made available for the introduced additional elements, since they must be introduced between the base support and the core element. Since the core element contributes to the stability of the base support, the available space can not be arbitrarily large. In addition, an electrical component in such a cavity is exposed to mechanical stresses, which contributes to premature wear.

Thus, the task of developing an instrument carrier and a motor vehicle to the effect that additional storage space for components of the motor vehicle is provided.

The object is achieved by an instrument carrier of a motor vehicle according to claim 1 and by a motor vehicle according to the independent claim 13. Further developments are the subject of the dependent claims.

In the following, an instrument carrier of a motor vehicle will be described, wherein the instrument carrier has at least one cavity lying transversely to the direction of travel in an end region, which has an inner surface forming an insertion contour, wherein at least one accumulator is arranged in the cavity.

Due to its functions, the wearing of a dashboard and most of the body stiffening, the instrument carrier has a large volume. This volume is used to accommodate at least one accumulator, which can increase the packing density in the motor vehicle and the space utilization is improved. The arrangement of the at least one accumulator in the cavity of the instrument carrier, which is well protected.

In a first further embodiment, a housing may be provided, in which the at least one accumulator and / or another vehicle component is arranged. Thus, a part of the cavity can be used by the at least one accumulator, another part for another vehicle component.

In a further refinement that goes beyond this, it can be provided that the at least one accumulator and / or the housing have an outer surface adapted to the insertion contour, so that the housing sits in the cavity with minimal play or no play, so that noises are generated during movement by movement of the housing can be avoided relative to the cavity and at the same time the mechanical stress on the vehicle component is reduced in the housing.

In another further embodiment, the vehicle component may be a liquid container. The liquid container may in particular be a windscreen wiper water container. The instrument carrier is often spatially arranged in the vicinity of a windshield of the motor vehicle, so that a provision of a liquid container, in particular mop water container, in the instrument carrier storage of mop water in the vicinity of the disc is possible. This can save space in the engine compartment and short cable routes are possible. In addition, a freezing of the liquid in winter is less likely, since the instrument panel is heated by the passenger compartment of the motor vehicle. The arrangement increases the ease of maintenance and facilitates the positioning of the other components and units in the engine compartment.

In another further embodiment, the vehicle component may be a printed circuit board. On the circuit board electrical and electronic components and connections can be arranged. The circuit board can form a module, in particular a control module. As a result, electrical component can be introduced into the instrument carrier.

In another further embodiment, both end regions arranged transversely to the direction of travel (left and right) can form corresponding cavities and receive the least one accumulator and / or the housing. Both cavities may be used to store accumulators, liquid containers or printed circuit boards or one side or a housing may be provided for at least one accumulator, the other side being provided for a liquid container and / or for one or more printed circuit boards.

In another further embodiment, the housing may have a holding structure for the at least one rechargeable battery or the vehicle component. As a result, the vehicle component can be securely arranged in the housing.

In a further embodiment, the housing may have a holding structure for a further vehicle component. As a result, the space utilization can be optimized in the housing. For example, two circuit boards can be arranged back to back to each other.

In another further embodiment, the housing may have a passage opening. This allows access to the vehicle component cause. Depending on the configuration can be passed through the passage opening, for example, a liquid line or a cable or a cable harness.

In another further embodiment, the instrument carrier may have at least one opening arranged on the circumference. As a result, the at least one accumulator and / or the vehicle component can be reached from outside through the instrument carrier. In particular, the opening in the instrument carrier and the passage opening in the housing may be arranged overlapping.

In another further embodiment, an interface can be arranged on the housing. This makes it possible to realize a contact with the arranged inside the housing at least one accumulator from the outside.

In another further embodiment, the cavity may be cylindrical. This facilitates the insertion of the at least one accumulator and / or housing into the cavity.

In another further embodiment, the instrument carrier may have a stop for the at least one accumulator or the housing. This allows the insertion depth of the housing to be defined. A corresponding stop can be indicated for example by one or more projections.

In another further embodiment, the cavity may have a substantially closed peripheral surface. As a result, the cavity can serve for stiffening the structure. An exception may be given in some embodiments by the at least one opening described above.

A first independent subject relates to a motor vehicle having an instrument carrier of the type described above. A corresponding motor vehicle has a greater space density than conventional motor vehicles.

The motor vehicle may in particular be a hybrid or electric vehicle. Electric vehicles have to accommodate a large number of storage batteries for energy storage, so that the storage space gained in the instrument carrier is structurally helpful. In addition, the corresponding at least one accumulator is housed protected.

In a first further refinement of the motor vehicle, an end face of the instrument carrier is arranged in the opening region of a door of the motor vehicle. This allows easy access to the housing and thereby to the vehicle component located inside the housing, thereby facilitating repair and maintenance.

Another further aspect provides a dashboard, which has an opening in the region of the front side of the instrument carrier and a cover for closing the opening. In this way, an aesthetic and uninterrupted appearance of the dashboard can be achieved.

Further features and details will become apparent from the following description, in which - where appropriate, with reference to the drawings - at least one embodiment is described in detail. Described and / or illustrated features form the subject matter, or independently of the claims, either alone or in any meaningful combination, and in particular may additionally be the subject of one or more separate applications.
