Problems solved by technology

But the disadvantage is that, for example, in the event of an accident and the failure of the electric system, the door can only be moved with great force because of the strong damping effect via the permanent magnets
This can be problematic especially if elderly people or children are sitting in the car and they can only open the doors with difficulty or possibly not at all

Embodiment Construction

[0170] figure 1 A schematic plan view of a parked motor vehicle 100 is shown, in which case two door mechanisms 53 designed as doors are provided here, which are both open. The doors are generally in an angular position 13 . Each door is part of a door part 50 which in this case comprises a door 53 . Both doors 53 may be attached to the door part 50 . The door part 50 includes damping means. The door part 50 or the damping device 1 each comprise a connection unit 51 , 52 for connecting to the support structure 101 of the vehicle 100 and the door 53 to pivotably hold the door on the support structure 101 . Here, the door can consist of a plurality of units, which are all pivotable and articulated to each other. The door may be held for rotation about one or more than two pivot axes. Hatching is used to show the door 53 in the closed position 2 in which the door in this case ends flush with the vehicle.

Abstract

A door part (50) having a controllable damping device (1) filled with a magneto-rheological fluid (6) as a working fluid, comprising two connecting units (51, 52) movable relative to each other, the two One of the two connecting units (51, 52) can be connected to the supporting structure, and the other of the two connecting units (51, 52) can be connected to especially the movable door mechanism (53) of the vehicle (100), so that when closing Movement (53) of the movable door mechanism is controllably damped between position (2) and open position (3). The magnetorheological damping device (1) comprises a piston unit (30) and a cylinder unit (31) surrounding the piston unit (30), wherein the piston unit (30) divides the cylinder volume (32) into two chambers (33,34 ). The piston unit (31) has a first piston rod (43) extending through the first chamber (33) and a second piston rod (44) extending through the second chamber (34).

Description

technical field [0001] The invention relates to a door element with a controllable damping device, in particular for a motor vehicle. In this case, the door part comprises two connecting units which are movable relative to each other, the relative movement of which can be at least braked by a controllable damping device. In this case, one of the two connecting units can be connectable or connectable to the support structure and the other of the two connecting units can be connectable or connectable to, in particular, a pivotable door mechanism of the vehicle. Background technique [0002] Various door components are known in the prior art, with which a predetermined damping of the door movement and, in particular, a predetermined fixing of the door in a predetermined angular position can be achieved. Mechanical systems are usually used for this, which are inexpensive and allow the motor vehicle door to be fixed in two or three corner positions. In this way, the user can mo...
