Definitions

  • Blocking device for at least partially blocking a relative movement
  • the present invention relates to a blocking device for at least partially blocking a relative movement between an immovable and a movable part of a device.
  • a generic blocking device in an operating element in which a ball can be brought into engagement with an introduced in the movable part of the operating element locking profile to block at least one movement of the movable part.
  • the ball is moved by an electromagnet between two end positions.
  • the electromagnet is arranged on one of the limbs of a U-shaped iron core.
  • a permanent magnet abuts one of its poles at the junction between the two legs. If the electromagnet is de-energized, the permanent magnet in the iron core forms a magnetic field that is identical in both legs of the iron core and holds the ball in its current position. While the electromagnet is energized, a superimposed magnetic field results in the iron core, through which the ball moves from its current position to the other end position.
  • the blocking device described above has several disadvantages.
  • the permanent magnet must generate a strong magnetic field in order to keep the ball in position even with vibrations. If the ball is still brought from its position by vibrations or other unwanted influences, there is the possibility that the ball unintentionally gets into its other end position and held there.
  • the individual components must be manufactured and arranged very precisely.
  • the ends of the legs of the iron core over their entire end face must have a constant distance from the running surface of the ball. This distance must not exceed a certain maximum value, since the magnetic force acting on the ball would otherwise be too small.
  • the distance between the legs of the iron core must be slightly larger than the distance between the two end positions of the ball, so that the end positions of the ball in a sufficiently strong area of the magnetic field. This leads to limitations in the design of the control.
  • a blocking device for at least partially blocking a relative movement between an immovable and a movable part of a device has according to claim 1 at least one permanent magnet, an electromagnet on a ferromagnetic core, a locking profile in the movable part and a blocking element, which can be brought into engagement with the locking profile, on.
  • the permanent magnet is movably arranged in the device and movable between at least two end positions.
  • the permanent magnet is disposed between the open end of the ferromagnetic core and the blocking element.
  • the blocking element is, for example, a magnetizable ball. In principle, the blocking element can have any suitable shape.
  • the blocking element consists of a magnetic or magnetizable material, so that a force is exerted on the blocking element by a magnetic field. In each of its end positions, the permanent magnet is located in the region of the end of a leg of the ferromagnetic core. The magnetic field of the permanent magnet extends into the legs of the ferromagnetic core and thus holds the permanent magnet in position.
  • a change in position of the permanent magnet is achieved in that the electromagnet is energized and, as a result, forms a magnetic field in the ferromagnetic core.
  • the current direction through the electromagnet and thus the direction of the magnetic field in the ferromagnetic core is selected so that the magnetic pole forms on the leg, in the region of which the permanent magnet is located, which corresponds to the ferromagnetic core facing pole of the permanent magnet. This leads to a repulsion of the permanent magnet from its current position to the other end position.
  • the movable permanent magnet is guided in such a way that overturning of the permanent magnet is prevented. Tipping over in this context means that the Permanent magnet rotates such that the ferromagnetic core of the other magnetic pole faces.
  • the blocking element which is located in the region of the magnetic field of the permanent magnet, follows the movement of the permanent magnet and is, for example, likewise movable between two end positions. In an end position, the blocking element is in engagement with the locking profile in the movable part of the device and thus blocks the movement of the movable part in at least one direction. In another end position, the blocking element is not engaged with the locking profile. Due to the relative proximity between the blocking element and the permanent magnet, a comparatively weak permanent magnet already leads to a strong magnetic force on the blocking element and thus to a high vibration resistance.
  • the ferromag netic core which consists for example of iron, formed substantially U-shaped.
  • the distances between the ferromagnetic core and the permanent magnet or the permanent magnet and the blocking element can be chosen significantly larger than in the known from the prior art operating element.
  • the electromagnet disposed on the ferromagnetic core and the movable permanent magnet form a mechanical, bi-stable flip-flop, the blocking element following the position of the permanent magnet.
  • a movable permanent magnet has a further advantage when the blocking element blocks the movement of the movable part of the device.
  • the blocking element is jammed in the locking contour and therefore can not leave its position with a correspondingly large clamping force.
  • the position change of the ball is achieved by a short energization of the electromagnet. If the ball is trapped during energization, it does not change its position.
  • the permanent magnet is always movable and changes its position even when the blocking element is clamped, when the electromagnet is energized accordingly.
  • the blocking element follows the movement of the permanent magnet as soon as it is no longer clamped, even when the electromagnet is no longer energized.
  • the blocking device according to the invention can be used, for example, as an actuator in an operating element, in particular a turntable or a joystick. In a device designed as a turntable, a rotation direction is blocked with the blocking device, for example, or a tilting direction in the case of a joystick.
  • the control element with a blocking device according to the invention can be used in particular in a motor vehicle.
  • the device is, for example, a door, in particular a door in a motor vehicle.
  • the blocking device With the blocking device, the opening of the door is blocked and thus the door lockable, for example, to restrict access or as a child safety.
  • the device is an ignition lock.
  • the ignition key can be locked in the lock, so that the key can not be removed, for example, while driving.
  • the device is an actuating device, for example an adjusting device for a steering wheel or a seat, in particular in a motor vehicle.

  • Adjacent to the pockets 8 and 13 are guide elements 15 and 16, respectively, which receive the translationally movable permanent magnets 6 and 11, respectively.
  • Adjacent to the guide elements 15 and 16 are U-shaped iron cores 5 and 10, each carrying an electromagnet 4 and 9, respectively.

  • the permanent magnet 6 rests with its south pole facing the iron core 5 on a running surface 17 of the guide element 15. Due to the magnetic attraction between the north pole in the upper leg of the iron core 5 and the south pole of the permanent magnet 6, the permanent magnet 6 is brought into its position shown in Figure 3 or held there.
