The present invention relates to a hinge system of an electric door comprising a control module, an intelligent automatic recognition system for installing in a door or a door frame and including a recognition device and a sensing module, and a hinge assembly. The hinge assembly comprises a pivot housing, a power unit disposed in the pivot housing and electrically connected to the control module, a first hinge member having a first knuckle for sleeving on the pivot housing and a second hinge member connected to two ends of the pivot housing. The power unit comprises a motor assembly having a motor axis, a reduction gearbox having one end connected to the motor axis, a gear shaft and plural planetary gears, and a gear connected to the gear shaft of the reduction gearbox.

A foot operable door opener operates, without using one's hands, and without an electrical assist. The entrance cycle is initiated by stepping on a pedal. This force drives the pedal a ¼ turn, engaging a soft wheel to open the door. The pedal is hard linked to a crank arm which goes into a unidirectional crank shaft hub to turn the wheel. The downward pressure from the pedal pivots a ratcheted hinge connected to a bracketed spring-loaded wheel assembly to keep constant pressure to the ground. A gear box or multiple pumps of the pedal turns the wheel two or more 360 degrees rotations, opening the door to allow the entrant to pass until the foot pedal is disengaged. This action releases the ratcheting hinge mechanism, allowing the spring assisted wheel assemble to rotate to its original up position, releasing the wheel from the ground, allowing the door to close.

A drive device for moving a leaf, in particular a door leaf or window leaf, includes an electric machine. The electric machine is an axial flux machine having a stator, in particular a single stator, and a rotor, in particular a single rotor, which is rotatable relative to the stator about a machine axis.

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 door drive for a door of a vehicle includes a rotation motor, a first torque transmitting device for transmitting a first torque, and a second torque transmitting device for transmitting a second torque.
wherein

The door drive further includes a blocking device for blocking the first torque transmitting device, wherein the blocking device can be activated and deactivated, and the door drive has an actuating member for activating and/or deactivating the blocking device.

A refrigerator and a method for controlling the same are disclosed, which may automatically open or close a door and a method for controlling the same. The refrigerator may automatically open or close door(s) of the refrigerator by controlling a motor. After lapse of a predetermined time after the door of the refrigerator has been closed, the refrigerator operates a motor with an output used when the door is not opened, such that the refrigerator may remove noise while simultaneously maintaining a constant door opening time when the door is opened. In addition, when the door opening signal time is detected, the refrigerator may immediately opens the door.

An access control system for restricting access through a passageway includes a shaft rotatable about a central axis; a barrier fixed to the shaft to rotate therewith; and a brake assembly. The brake assembly includes a sun gear rotatable about the central axis, a carrier, and a ring gear, wherein one of the carrier or the ring gear is fixed against rotation and the other of the carrier or ring gear is connected to the shaft to rotate therewith. A plurality of planet gears are rotatably connected to the carrier, each planet gear being disposed between and engaging with each of the sun gear and the ring gear. The armature of an electromagnetic brake comprising an electromagnet and an armature is connected to or integral with the sun gear to rotate therewith. At least one of the electromagnet or the armature is moveable between an operative and an inoperative position.

A power closure actuator for powering a movable closure includes an output member configured to drive movement of the movable closure, a motor coupled through a gear reduction to drive the output member, and an integrated brake-clutch unit having an input configured to receive drive power from the electric motor. The brake-clutch unit provides independent braking and clutching between the electric motor and the output member via an electric brake actuator and an electric clutch actuator, respectively. Brake and clutch portions of the brake-clutch unit act on a rotor, and brake force can be maintained on the rotor without powering the brake actuator. A clutch disc is biased disengaged from the rotor. The integrated brake-clutch unit provides a drive state between the electric motor and the output member when the brake portion is released concurrently with the clutch portion establishing a power coupling between the clutch disc and the rotor.

A control unit for establishing a functional connection between two gearing components comprises at least one control element, which can be moved in order to switch the control unit between different switching states, wherein the at least one control element is configured to provide a retaining force between the gearing components in a first switching state, and to allow movement of the gearing components in relation to one another in a second switching state. An actuator is used to move the at least one control element. A control mechanism controls the actuator. It is provided thereby that the control mechanism is configured to activate the actuator to switch the control unit from the first switching state to the second switching state, in order to move the at least one control element to reduce the retaining force (FH) based on a predetermined delay function (VF).

A spindle drive assembly for opening and/or closing a vehicle flap is described, having a spindle extending along a spindle drive axis and a spindle drive motor which is drivingly coupled to the spindle via a gearing and the motor shaft of which is arranged substantially coaxially with the spindle drive axis, wherein a coupling compensating an axial offset and a hysteresis brake are drivingly interposed between the spindle drive motor and the gearing. In addition, a vehicle flap with such a spindle drive assembly is presented.
