The drive device (1) is for a pivoting vehicle flap, to provide automatic pivoting and a flexible holding force for the vehicle flap, such that at least one of the first brake element and the second brake element can be displaced in the axial direction (x) of the spindle rod (12) by the magnetic field.

An actuation system and method of operation for moving a closure panel in one of a normal drive state and a back drive state are provided. The actuation system includes a mechanical coupling for moving the closure panel. A motor with a shaft is directly and operably connected to the mechanical coupling to directly move the mechanical coupling. A sensor detects movement of the closure panel and couples to a controller connected to the motor. The controller moves the closure panel with the motor based on a detected motor movement command in the normal drive mode. The controller also detects movement of the closure panel using the at least one sensor and selectively brakes the movement of the closure panel based on the movement detected in the back drive state.

A fitting arrangement for a leaf of a sliding window or door that can be moved away in parallel, includes a control unit having a mounting part for fixing on the leaf and an adjusting part which is displaceable relative to the mounting part for moving the leaf away in parallel. A movement unit is fastened to the control unit and has an energy storage device and an activation element for the energy storage device. A closure arrangement for a building opening, includes a frame, the control unit and the adjusting part. The leaf which, in a closed position, can, by means of the control unit, be brought up to the frame and be moved away from the frame in parallel, so the leaf is displaceable along a guide rail of the frame. The movement unit supports an automatic movement of the leaf along the guide rail.

Disclosed is a hidden shower door with a low-rail sliding assembly, including an upper rail assembly (10), a movable door assembly (20), a vertical frame assembly (30), and a bottom guide part (40), wherein the upper rail assembly (10) includes an upper rail (1010), a damping trigger (1020), and sliding assemblies (1030), and the sliding assemblies (1030) each are mounted in the upper rail (1010); the sliding assemblies (1030) each include pulleys (10311), pulley brackets (1060), adjusting screws (10312), a damper (1050), and a damper bracket (1040); the pulleys (10311) are mounted on the pulley brackets (1060). The two pulley brackets (1060) are connected and fixed to two ends of the damper bracket (1040) respectively, and the damper (1050) is mounted in a damper accommodating groove (1041) of the damper bracket (1040); the upper rail (1010) is provided with a first bottom plate (1011).

Provided is a motorized drive system for actuating a door, including at least one gear having a spindle axis and a drive axis, wherein the gear assembly is designed to convert a rotational movement about the drive axis into a rotational movement about the spindle axis; at least one spindle assembly having a threaded spindle which can be rotated about a spindle axis, wherein the threaded spindle is mechanically coupled to a part of the gear assembly that can be rotated about the spindle axis, and at least one drive assembly for driving the threaded spindle with a drive shaft, wherein the drive shaft is mechanically coupled to a part of the gear assembly that can be rotated about the drive axis.

The present subject matter relates to hinge connectors with rotation control units. In an example, a hinge connector may couple a base unit with a cover unit of a device. The hinge connector includes hinge shaft. The rotation control unit is to control the rotation of the hinge shaft and stop a free-rotation of the hinge shaft at a predefined angle with respect to the base unit.

A vehicle door checker integrated with a power drive unit for an automobile door includes a direct current permanent magnet electric motor subject to cogging torque. The electric motor includes a central shaft. The vehicle door checker also includes a cogging torque increase device that is mounted to the central shaft externally of the motor. The cogging torque increase device includes pairs of oppositely magnetized permanent magnets that are mounted coaxially in a stator and rotor respectively about the motor shaft. The stator magnets and the rotor magnets shift into and out of alignment with each other as the shaft is rotated such that the motor is held in multiple discrete stable positions that correspond to check positions of an automobile door.

A spindle drive for the motor-driven adjustment of an adjustable element including a housing, a body connector, an adjustable element connector, a spindle nut, a spindle disposed in the housing and operatively connected to the spindle nut and the adjustable element. Either the spindle translate along a drive axis, extending in an axial direction, to move the adjustable element between an open position and a closed position, a planetary gear assembly operatively coupled to and disposed between the spindle nut and the motor, the planetary gear assembly including, a sun wheel, a planet carrier, a gear carried by the planet carrier, an annulus connected to the housing and arranged coaxially to the sun wheel, and a first frictional element non-rotatably fixed with respect to the housing and connected to either the planet gear or the planet carrier.
