Description

A cage nut and a motor vehicle are described.

Cage nuts and motor vehicles of the type mentioned are known in the prior art.

In the case of motor vehicles, various components are frequently fixed to one another by means of screw connections. In order to be able to compensate for manufacturing tolerances, a tolerance compensation system is necessary in many cases. An example is the attachment of batteries or accumulators in motor vehicles such as Trucks. Thrust systems are sometimes used here, in which the accumulator is inserted into a battery holder and fixed there.

It is known to use cage nuts for these purposes where a nut is slidable in one dimension in a fixed, e.g. welded to the battery holder, cage is arranged. The cage nut can compensate to a certain extent for the corresponding tolerances.

A cage nut is from, for example EP 3 354 914 B1 known. The cage nut comprises a nut with a radially projecting flange, which has two side faces arranged parallel to one another and a sleeve-like screw receptacle, a holding plate with a cover plate, which is arranged on two opposite sides and parallel to one another and has a perpendicularly bent leg, which is provided with a through-opening which extends from the The screw holder of the nut is penetrated, as well as a connecting bush which encloses the screw holder of the nut and which has at one end a first collar for engaging the flange of the nut and at its opposite end a second collar, which collar, the cover plate of the retaining plate on both sides in the area partially cover the passage opening, the second collar being designed to be elastic and at least partially curved in the direction of the first collar, the second collar being excessive in relation to the passage opening has, such that it can be pressed through the passage opening, after which it resumes its original shape.

A disadvantage of the known cage nuts is that when positioning the object to be fixed, e.g. when inserting an accumulator into a battery holder, the object, here the accumulator, can get caught on a cage nut, which hinders the assembly process or, in the worst case, can damage the object, here the accumulator.

Thus, the task arises to further develop cage nuts and motor vehicles in such a way that an easier mounting of objects on cage nuts is possible and that there is less risk of damage to the objects to be assembled.

The object is achieved by a cage nut according to claim 1 and a motor vehicle according to the independent claim 8. Further refinements and developments are the subject of the dependent claims.

• - einem Mutternkörper mit einem radial überstehenden, zwei parallel zueinander gegenüberliegend angeordnete Seitenflächen aufweisenden Flansch und einer hülsenartigen Schraubenaufnahme,
• - einem Käfig mit einem an zwei gegenüberliegenden Seiten parallel zueinander angeordnete rechtwinklig von einer Montageseite abgekantete Schenkel aufweisenden Deckblech, das mit einer Durchtrittsöffnung versehen ist, die von der Schraubenaufnahme des Mutternkörpers durchdrungen ist, wobei die Schenkel an ihren freien Enden Fügebereiche zur Festlegung an einer Kraftfahrzeugkarosseriekomponente aufweisen, sowie
• - einer Führungsplatte, welche die Schraubenaufnahme des Mutternkörpers umschließt und auf der dem Flansch des Mutternkörpers gegenüberliegenden Montageseite des Deckblechs angeordnet ist und somit den Mutternkörper am Käfig sichert,

wobei an dem Käfig wenigstens eine Anlauframpe quer zu den Schenkeln angeordnet ist, die einen Bereich zwischen der Kraftfahrzeugkarosseriekomponente bis zur Schraubenaufnahme zumindest teilweise abdeckt.A cage nut is described with

• a nut body with a radially projecting flange having two side surfaces arranged opposite one another and a sleeve-like screw receptacle,
• - A cage with a parallel arranged on two opposite sides mutually perpendicular leg from a mounting side leg cover, which is provided with a passage opening which is penetrated by the screw receptacle of the nut body, the legs at their free ends joining areas for fixing to a motor vehicle body component have, as well
• a guide plate which encloses the screw receptacle of the nut body and is arranged on the mounting side of the cover plate opposite the flange of the nut body and thus secures the nut body on the cage,

wherein at least one starting ramp is arranged on the cage transversely to the legs and at least partially covers an area between the motor vehicle body component and the screw receptacle.

Due to the fact that at least one starting ramp is arranged transversely to the legs on the cage, an object to be fastened, for example an accumulator, can come into contact with the cage, but is transported via the starting ramp to a suitable position without damage, so that the assembly process can be easier than with conventional cage nuts. At the same time, the risk of damage is significantly reduced.

Corresponding cages can be manufactured cost-effectively as stamped and deep-drawn components.

In a first further embodiment it can be provided that the joining areas are welding studs.

This makes it possible to fix the cage by welding. In the case of a battery holder, the cage can, for example, be welded to the battery holder using the welding pins.

In a further development, it can be provided that the starting ramp has at least one welding spigot.

This makes it possible to fix the starting ramp in the same way as the rest of the cage by welding and thus to secure it. In addition, in such an embodiment the entire area between the welding point and the top of the cage is covered, so that even extreme tolerances can be compensated for.

In a further development, it can be provided that the starting ramp forms an undercut.

In this way, an inadvertent slipping out of the object to be fastened against a mounting direction can be prevented.

In a further development, it can be provided that the passage opening is designed as an elongated hole, so that the nut body is arranged to be displaceable relative to the cage.

In this way, a tolerance compensation range can be defined, within which an assembly on the cage nut is possible.

In a further development, it can be provided that the guide plate consists of plastic.

In this way, the guide plate can be easily connected to the screw holder of the nut body by clipping the guide plate onto the screw holder. This is possible due to the elasticity of the plastic guide plate.

In a further development, it can be provided that the guide plate is locked in place with the screw receptacle.

This allows easy assembly, disassembly and, if necessary, maintenance of a cage nut without destroying the cage.

A first independent object relates to a motor vehicle with at least one cage nut of the type described above.

In a first further embodiment it can be provided that the motor vehicle body component is a battery holder.

Further advantages, features and details result from the following description, in which - if necessary with reference to the drawing - at least one exemplary embodiment is described in detail. Identical, similar and / or functionally identical parts are provided with the same reference symbols.
