Definitions

  • the invention relates to a door arrester for detecting a motor vehicle door or a method for blocking a door arrester.
  • the door arrester comprises a spindle rod which is pivotally connected at one end to a vehicle body and received at the other end in the vehicle door, where a braking or locking device is arranged.
  • the braking or locking device is accommodated in a holding housing, wherein the holding housing surrounds the spindle rod substantially rotationally symmetrical.
  • the spindle rod passes through a central recess of the holding housing.
  • the spindle rod has an external thread, which is in engagement with an internal thread of a spindle nut, wherein the spindle nut is rotatably mounted in the holding housing by means of a rolling bearing.
  • a longitudinally displaceable electromagnet which is designed as a coil arrangement in a housing, displaces the braking surfaces counter to the force application direction of the spring during energization, so that the brake pad is brought out of material contact with the spindle nut, whereby the spindle nut can rotate freely and the vehicle door is no longer detected, but is released.
  • the longitudinally displaceable electromagnet can be triggered by means of sensors.
  • DE 10 2007 026 796 A1 shows an electrically controllable door lock for vehicle doors.
  • a rack support rod gear housing accommodated, wherein the rack is connected to the body via a bearing.
  • the rack is in engagement with a gear of the gear housing, said gear being non-rotatably connected to a transmission gear, which is in engagement with another gear.
  • On one end side of the further gear discs are arranged.
  • a spring element is received in a coil housing and spaced from an end face of the coil housing, which is designed as a bearing surface, of the brake discs.
  • an annular coil is further arranged in an outer region of the coil housing, whereas the spring element is arranged in an inner region of the coil housing.
  • the brake discs and the coil housing made of a magnetizable material.
  • the magnetization of the material follows in that the brake discs are pressed against the support surface of the bobbin case, so that a frictional connection is formed and the door stops moving. Even with a termination of the energization of the coil, the magnetization is maintained and the vehicle door is secured in position, so that only an oppositely energized coil the brake disc again spaced from the support surface of the coil housing and the door release releases. It is intended to trigger the energization of the door detection by external sensors.
  • DE 10 2011 056 225 A1 shows a stepless door arrester, in which a transmission housing is fixed in a holding housing, wherein the holding housing is fixed to a vehicle door.
  • the door arrester comprises a spindle rod having a threaded portion and a non-threaded end portion, wherein the spindle rod at its end portion portion comprises a bearing for pivotal connection with the body and at the end portion facing away from the end stop.
  • the end stop limits a maximum opening travel of the vehicle door.
  • a spindle nut which is rotatably received in the transmission housing, engages with an internal thread in an external thread of the spindle rod. In the area of the unthreaded end section, the spindle nut slides over the spindle rod.
  • a displacement of the spindle nut over the spindle rod is Designed as frictionless as possible, so that the vehicle door can open unintentionally, for example, in a gust of wind.
  • the spindle nut is additionally provided with an external thread, which is in the manner of a bevel gear with a pinion of a power transmission element engaged.
  • a shaft connected to the force transmission element is connected to a cup-shaped friction element, which is resiliently received in a cup-shaped braking surface. If the vehicle door is now moved, the spindle nut rotates about the spindle rod and displaces the spindle rod relative to the transmission housing by generated axial forces.
  • a coefficient of friction between the cup-shaped friction member and the braking surface may be selected such that movement of the door has a desired resistance such that, for example, a sudden gust of wind is unable to inadvertently open the vehicle door.
  • the end portion of the spindle rod is provided so that during a closing operation of the vehicle door, the spindle nut does not have to rotate about the last distance to the thread of the spindle rod, but can slide over the end portion, so that a braking effect can not engage and closes the vehicle door reliably.
  • DE 10 2011 106 664 A1 shows a stepless door lock, in which a trained as a spindle rod support rod is axially displaceably mounted in a holding housing.
  • a spindle nut is received in the holding housing.
  • the spindle nut is in this case mounted in the manner of a rolling bearing rotatable about an axis of rotation of the spindle rod and has on an inner side a threaded bore which engages with a threaded bore of the spindle rod.
  • the holding housing comprises a permanent magnetic material and a cavity, which is formed coaxially to the axis of rotation of the spindle rod, so that an inner Wall with a smaller radius of the holding housing surrounds the spindle rod and an outer wall is arranged with a larger radius spaced from the axis of rotation of the spindle rod.
  • the mutually facing sides of the inner wall and the outer wall are magnetically differently polarized.
  • the holding housing and the brake shoes are permanently magnetically formed such that in a rest position of the vehicle door, the brake shoes are pressed by magnetic forces on the inner wall of the holding housing, which is arranged rotationally symmetrically between the spindle rod and the holding jaws.
  • the brake shoes By resting the brake shoes on the spindle rod facing inner wall of the holding housing of a rotational movement of the spindle nut is opposed to a frictional force.
  • the brake shoes By overcoming a breakaway torque, the brake shoes are lifted by means of a centripetal force despite the magnetically attractive effect of the inner wall of the housing and are displaced in a kind of floating state in the cavity between the inner wall and the outer wall.
  • the outer wall of the housing is designed as a permanent magnet such that its magnetic force acts repulsively on the brake shoes. If the axial displacement of the spindle clasp, for example, by a gust of wind, significantly increased, so does the rotational speed of the spindle nut and thereby the centripetal force on the brake shoes, so that the repulsion of the outer support housing is overcome and the brake shoes by the increased centripetal force in a material contact reach the outer wall, whereby a frictional force is generated which slows down the rotational speed of the spindle nut and thereby also a displacement speed of the spindle rod.
  • the door lock works according to the principle of the centrifugal brake and works without an external power supply.
  • FR 2 830 893 A1 describes a lock for a vehicle door, which is hingedly connected to a body part, in which a hingedly connected to the body part holding rod passes through a holder housing which is arranged in the flap, wherein the support rod has a toothed with a gear of the holder housing in Gear engagement is, wherein the gear is coupled to a permanent magnetic armature disc with a plurality of poles, which rotates with the gear opposite a fixed permanent magnetic armature disc.
  • oppositely poled portions of the armature discs tend to attract each other and thus counteract further rotation of the movable armature disc, so that for a rotational movement first a force must be applied, which acts as a braking force.
  • DE 199 21 213 A1 shows a stepless vehicle door arrester, in which a holding housing is connected via a hinge to a vehicle door or a body, and a spindle rod, which passes through the holding housing in the middle.
  • the spindle rod is rotatably connected to the vehicle door or the vehicle body.
  • the spindle rod engages in a thread of a spindle nut, wherein the spindle nut is rotatably received in a radial bearing.
  • two cup springs are supported on both inner sides of the holding housing in an extension direction of the spindle rod, wherein the disc springs are supported with their concave sides on support surfaces of the holding housing and supported on the opposite convex sides of the spindle nut.
  • balls are arranged in ball grooves on the disc springs.
  • the ball acts as a pivot point of a lever, so that a peripheral contact surface of the plate spring is lifted from the housing wall, so that the corresponding plate spring is no longer in direct contact with the holding housing, whereby a frictional force between the plate spring and the housing is reduced and the spindle nut is easier to rotate than at the beginning of a sliding process of the spindle rod.
  • the disc springs are mounted only by means of the balls on a corresponding holding housing side. It follows that when opening a vehicle door first an increased force must be expended, but that after applying this increased force, a vehicle door is easier to open, as the friction coefficient between disc spring and the spindle nut is lowered.
  • DE 44 35 720 A1 or. DE 198 32 502 C2 show a stepless locking device for a vehicle door, wherein in a closing or opening operation, a spindle rod with an external thread is displaced by an internal thread of a rotatable spindle nut.

  • the spindle nut is arranged on an end region of the support rod.
  • this provides the ability to easily install the spindle nut but easy to replace even if damaged.
  • a dimension of the support rod can be made smaller, otherwise the spindle nut would have to be completely absorbed into the cavity of the support rod. Inevitably, this leads to a larger dimension of the support rod.
  • this arrangement has the advantage that the length of the spindle rod is kept as small as possible, since the opening movement of the vehicle door of a certain Displacement of the spindle rod corresponds. If the spindle nut were connected inside the support rod, then the spindle rod would have to be extended by a distance from the end portion of the support rod to the bearing of the spindle nut inside the support rod.
  • the spindle rod is proportional to a pivoting of the door out of the support bar moved out. This ensures that a pivoting movement of the vehicle door is directly coupled to the movement of the spindle rod, so that stopping the movement of the spindle rod also stops the pivoting movement of the vehicle door.
