Abstract
The present disclosure relates to a sensor unit for the position determination of a powered door having a position sensor and a transmission stage for the connection of the position sensor to the drive shaft of the door, with the sensor unit having its own housing so that it can be installed independently of the drive unit of the door.
Claims24
A sensor unit to determine a position of a powered door, comprising:
- a position sensor;
- a drive shaft;
- a transmission stage to connect the position sensor to the drive shaft;
- and
- a housing configured to enable installation of the sensor unit independent of a drive unit of the door.
A door drive train, comprising:
- a drive unit;
- a drive shaft;
- and
- an independent sensor unit including:
- a position sensor;
- and
- a transmission stage connecting the position sensor to the drive shaft to cause one revolution of the drive shaft to correspond to one revolution of the position sensor and align an axis of rotation of the position sensor with an axis of rotation of the drive shaft drive such that the axes of rotation are parallel, wherein the sensor unit is configured to be mounted to a door separately from the drive unit.
A retrofit sensor unit to determine a position of a powered door, the sensor unit mechanically separate from a drive unit of the powered door, the sensor unit comprising:
- a position sensor including a reference point disk, the position sensor configured to recognize at least one end position and one start position of the powered door based on a position of the reference point disk;
- a transmission stage to connect the position sensor to a drive shaft of the powered door, the transmission stage including a hollow worm gear, the hollow worm gear forming an opening adapted to receive the drive shaft, wherein gear reduction of the hollow worm gear causes one revolution of the drive shaft to correspond to one revolution of the reference point disk, and the transmission stage including a bevel gear stage to align an axis of rotation of the position sensor with an axis of rotation of the drive shaft drive such that the axes of rotation are parallel;
- a housing configured to mount to the powered door independent of the drive unit, the housing forming a cut-out adapted to receive the drive shaft;
- and
- a control system to evaluate positional data from the position sensor and adjusting the position of the powered door based on the positional data.
