Abstract

The invention relates to a storage container (10) for a motor vehicle having a pivotably arranged cover (12) whose opening movement can be damped with at least one damping element (21), wherein the at least one damping element (21) is a viscoelastic damping element.

Description

The invention relates to a storage container for a motor vehicle with a pivotally arranged cover whose opening movement is damped with at least one damping element.

The DE 10 2004 047 378 B4 describes a damper device for a lid of a glove box. The damping device has a cam and a wave-shaped spring element which presses against the cam on. In this way, a counter force is generated between the cam and the spring element, with which an opening movement of the lid is damped.

In the DE 10 2006 006 851 A1 is also disclosed a glove box with a lid, wherein an opening movement of the lid is damped. For this purpose, stops, which are preferably made of an elastomer, provided to dampen the striking of the lid to a counter-stop.

A pivotally mounted component, which is reciprocable between two end positions, describes the DE 41 25 184 A1 , To prevent a hard stop during the movement from one to the other end position, a damping element is provided. The damping element is designed as an air-filled hollow organ made of a soft elastic material having at least one air escape opening.

The invention has the object to improve a storage container of the type mentioned in that a springback of a lid when reaching the end position of an open position of the lid can be reduced or completely prevented.

The invention solves this problem with a generic storage container, wherein according to the invention the at least one damping element is a viscoelastic damping element. The at least one damping element thus has viscoelastic damping properties. The at least one damping element may preferably comprise a viscoelastic material, such as a viscoelastic polyurethane foam, a viscoelastic thermoplastic elastomer or a viscoelastic fluid. Alternatively or additionally, the at least one damping element may have a combination of a spring element having elastic properties and a damping element having plastic properties. Due to the viscoelastic damping property of the damping element, springback of the cover upon reaching the end position of an open position is at least reduced.

The at least one damping element can be arranged between a housing of the storage container and an end region of the lid. In this way, the at least one damping element is compressed during the opening movement of the lid. By compressing the damping element, the kinetic energy of the lid is compensated, so that the lid opens with a slow motion and is finally braked gently in its final position without or with little spring back to a standstill.

In a preferred embodiment, the at least one damping element may be arranged in the region of a pivot bearing. Thus, only a slight deformation of the damping element is required to brake the lid.

Particularly simple in construction and thus inexpensive to manufacture is the storage container when the lid is driven by its weight.

However, it is alternatively or additionally possible to drive the lid with a spring force. If necessary, it can then also be moved against gravity or obliquely to open the storage container. The opening of the lid by means of spring force is particularly advantageous when the lid performs its opening movement upwards or sidewards.

For the same reason, the at least one damping element can be designed in the form of a cuboid. Depending on the installation space situation, however, the at least one damping element can also have a different shape, such as, for example, a round or semicircular disk or a body with a pentagonal or other polygonal cross section.

In a preferred embodiment, the storage container can be a storage compartment integrated in the motor vehicle, in particular a glove box.

In a further preferred embodiment, the storage container can be a container which can be arranged separately in the motor vehicle, in particular a cooling container which can be removed in the motor vehicle.

Hereinafter, an embodiment of a storage container will be explained in more detail with reference to the accompanying drawings.

• 2 a detailed view 1 in the region of a damping element in a closed position of the lid;
• 3 another detail view 1 in the region of the damping element in an open position of the lid.

1 shows a storage container 10 which is provided as a glove box in a motor vehicle. The storage container 10 has a housing 11 and a lid pivotally mounted in contrast 12 on. The lid 12 is shown in a closed position and in an open position.

The lid 12 is in a pivot bearing 20 pivotally mounted (see 2 ). A viscoelastic damping element 21 is between an end area 22 of the lid 12 and the housing 11 arranged. The damping element 21 is thus in the area of the pivot bearing 20 , The damping element 21 is formed in this embodiment as a body having a pentagonal cross section. Exemplary suitable viscoelastic damping elements are z. B. marketed as so-called shock absorption slabs SLAB from the company. ACE shock absorber GmbH.

In a closed position of the lid 12 is the end 22 of the lid 12 on the damping element 21 at. The damping element 21 is at least essentially relaxed and undeformed (see 2 ). To open the dust container 10 the lid moves 12 clockwise from top to bottom (see 1 ). The lid 12 is driven by its weight. During the opening movement, the damping element 21 pressed together. This results in the damping element 21 a depression 23 (please refer 3 ). By compressing the damping element 21 becomes the kinetic energy of the lid 12 in deformation energy of the damping element 21 transformed. This opens the lid 12 with a slow movement. When reaching its end position, the lid 12 gently braked to zero with little or no springback.

To close the dust container 10 becomes the lid 12 moved counterclockwise from bottom to top. During this movement, the damping element becomes 21 increasingly relaxed and gradually returns to its original shape. If the lid 12 has reached its closed position, the damping element 21 completely or at least largely relaxed and has regained its original shape.
