Definitions

  • the present invention relates to a mirror actuator housing construction, in particular for a wing mirror of a vehicle, comprising a mirror housing frame having an actuator housing and a mirror-adjusting plate with mirror mounted therein, in which actuator housing drive means are present for rotating the mirror-adjusting plate with mirror relative to the mirror housing frame about a mirror rotation point located adjacent the mirror-adjusting plate. It is known to fixedly mount the actuator housing on the mirror housing frame and to fix the mirror-adjusting plate with mirror on the actuator housing via a ball joint construction.
  • the drive means are typically formed by two motors, each having a gear transmission mechanism for driving a relevant spindle to effect a translatory movement of the spindle in the longitudinal direction thereof. Since this spindle engages the mirror-adjusting plate with mirror in a point spaced from the mirror rotation point, there is thereby obtained a tilting of the mirror-adjusting plate about a relevant virtual axis through the mirror rotation point defined by the ball joint construction.
  • the object of the invention is to enable a more compact construction of the actuator housing.

  • the construction as described further enables providing the holder with an electric plug terminal, while on the mirror-adjusting plate, a separate electric terminal is present for an electric connection to the plug terminal on the actuator housing, enabling ready through-connecting by looping.

  • the movement mechanism enables a mirror actuator housing construction wherein the mirror rotation point S (see Fig. 39) is a virtual rotation point, formed by the intersection of the X-axis and the Y- axis, relative to which the actuator housing, i.e. the holder 1 with the support 21 and accessories, is movably connected to the mirror housing frame, including bowl 2, while the mirror-adjusting plate 33 with mirror 34 is fixedly mounted on the actuator housing.
  • a mirror actuator housing construction is enabled wherein the drive means, i.e. the actuator 35, in the actuator housing on the one hand and the mirror-adjusting plate 33 with mirror 34 on the other, are located on either side of the rotation point S of the mirror-adjusting plate 33.
  • the electrically adjustable mirror construction hitherto described is further particularly suitable for fitting an electric wiring for realizing, apart from the electric mirror adjustment, other functions for the use of the mirror in the mirror housing.
  • Such functions may for instance relate to a mirror heating, electrically dimming of incident light, keeping the mirror water-free through vibrations, and the like.

Abstract

Cette invention concerne un ensemble boîtier d'actionneur de miroir, comprenant une armature de boîtier de miroir présentant un boîtier d'actionneur et une plaque de réglage de miroir, à l'intérieur duquel se trouve le miroir. Des dispositifs d'entraînement situés dans le boîtier d'actionneur servent à faire tourner la plaque de réglage de miroir avec le miroir par rapport à l'armature de boîtier de miroir autour d'un point de rotation de miroir situé à proximité de la plaque de réglage de miroir. Le point de rotation de miroir est un point de rotation virtuel auquel le boîtier d'actionneur est relié pour pouvoir tourner par rapport à l'armature de boîtier de miroir, alors que la plaque de réglage de miroir et le miroir sont montés fixes sur le boîtier d'actionneur. Le boîtier d'actionneur et les éléments fixés à l'intérieur de celui-ci peut être encliquetés sur l'armature de boîtier de miroir pour former une unité.
