Door with automatic opening and closing, including a door panel, a support column fixed to the door panel and suitable for rotating around its longitudinal axis in such a way to move the door panel between two end-of-travel positions, an electric motor for actuating the support column and a drive unit for transmitting the motion from the electric motor to the support column. The drive unit has a first drive element connected to the electric motor and a second drive element connected to the support column, wherein the drive unit includes a clutch unit that is interposed between the first drive element and the electric motor or between the second drive element and the support column. The door also has an automatic lock that completes the automation of the door by detectors.

A one-way damper mechanism, which can properly operate a damper by appropriately engaging a gear and a rotary damper so as to reduce wobbling, is provided. A one-way damper mechanism includes a gear-holding member provided with a gear engaging with a rack, which relatively moves to the rack; and a damper-holding member provided with a rotary damper, which relatively moves to the rack, and the one-way damper mechanism changes between a braking state wherein the gear and a damper gear are engaged, and a release state wherein the gear and the damper gear are separated.

A hinge arrangement having a first hinge part and having a second hinge part, which are connected to one another such that they can pivot, a first hinge pin being formed on the first hinge part, on which a first hinge sleeve is pivotably mounted, which forms a first sliding bearing with the first hinge pin, a dimensionally stable support part being connected to the first hinge sleeve. A first axial protrusion is formed on a first axial end face of the first hinge pin, which engages in an arcuate first groove of the first hinge sleeve, wherein a circumferential first side wall of the first groove together with the first axial end face and an inner side of an end cover fixed at the end of the first hinge sleeve delimits a working space which is filled with a damping fluid for damping a relative movement of the first axial protrusion with respect to the first groove.

An automatic door device includes a driving motor and a transmission system. An input end of the transmission system is coupled to an output shaft of the driving motor, an output end of the transmission system is coupled to a door shaft, and the transmission system has a transmission link to transmit an output torque of the driving motor to the door shaft. A clutch mechanism is disposed on the transmission link of the transmission system. Accordingly, when the door is subjected to an external force, the transmission link between the door and the driving motor can be automatically disconnected, so that while an automatic door function implemented, it is ensured that a user may not be affected by the resistance brought by the automatic door device when the user opens/closes the door manually, thereby optimizing user experience.

A hinge mechanism includes at least two hinge modules and at least one switching assembly disposed between the adjacent two hinge modules and including a first and second rotating members rotating coaxially with respect to each other. The first rotating member is coaxially disposed at one of the adjacent hinge modules to rotate synchronously. The second rotating member is coaxially disposed at the other one of the adjacent hinge modules to rotate synchronously. The first rotating member has a first driving portion, and the second rotating member has a second driving portion. The first and second driving portions are located on rotating paths of each other, and an idle stroke is provided between the first and second driving portions along the rotating paths. When the first driving portion and the second driving portion pass through the idle stroke, torque forces generated by the adjacent two hinge modules are disconnected.

The invention relates to a drive train of a drive (2) for the motorized displacement of a closure element (3) of a motor vehicle, wherein at least one friction engagement mechanism (6) is provided in order to provide a friction torque, wherein the friction engagement mechanism (6) is a component of a coupling mechanism (7) of the drive train (1) for coupling two drive components (11, 12) of the drive train (1) in a rotationally secure manner, wherein the coupling mechanism (7) is coupled in a rotationally secure manner via a motor-side coupling piece (7a) to a motor-side component of the drive components (11) and via a coupling piece (7b) remote from the motor to a component remote from the motor of the drive components (12), wherein the coupling mechanism (7) has a plurality of friction engagement elements (8, 9, 10) which can be rotated about a drive axle (X) and which are arranged coaxially relative to each other and which form the friction engagement mechanism (6), wherein a central element of the friction engagement elements (8) is in frictional engagement with two additional elements of the friction engagement elements (9, 10). It is proposed that the friction engagement elements (8, 9, 10) be arranged concentrically relative to each other at least in portions and that the central friction engagement element (8) be a tolerance ring (13) and be clamped radially between the two additional elements of the friction engagement elements (9, 10) in order to provide a friction engagement connection.

A door presenting device for a motor vehicle door element having an electric drive unit and an actuating means, wherein the actuating means can be adjusted by means of the drive unit and a gear mechanism arranged between the actuating means and the drive unit, with the result that a movement of the door element can be enabled, and further having a locking means. The door element can be maintained in position by means of the locking means and the locking means can be electrically actuated, namely indirectly, preferably manually, actuated.

An exemplary closure assembly includes a rail assembly and a door assembly movably mounted to the rail assembly. The door assembly includes a rotary damper having a pinion, and the rail assembly includes a rack member operable to engage the pinion. As the door moves from first position to a second position, the rack member engages the pinion, thereby causing the pinion to rotate in a first rotational direction. The rotary damper resists rotation of the pinion in the first direction, thereby slowing movement of the door toward the second position. The rotary damper may be a one-way damper that does not resist rotation of the pinion in a second rotational direction such that the rotary damper does not resist movement of the door from the second position toward the first position.

During the transition from the opening to the closing movement of a glove compartment door, or vice versa, undesirable noises (“clicking”/“popping”) can be reduced by providing regions of a housing surrounding a rotation damper with a contact region made of a material having a lower modulus of elasticity than the material of the remainder of the housing.

A cooling device includes a body, a drawer door attached to the body by rails in a slidable manner, and a door opening assistant for facilitating opening of the drawer door. As an improvement, at least two door closing assistants, that are configured to close the drawer door when the drawer door reaches a predetermined position, are provided on the body and/or the drawer door in such a way that the door opening assistant remains at a location between the at least two door closing assistants.
