Definitions
- Coupling device for the articulated connection of the mirror glass support of a motor vehicle rear view mirror with the housing of the mirror drive
- the invention relates to a coupling device for the articulated connection of the mirror glass support of a motor vehicle rear view mirror to the housing of the mirror drive
- the mirror glass support which is adjustable in two mutually perpendicular directions with respect to the fixed drive housing, is provided with a dome-shaped projection which, with the interposition of a spherical shell in a receptacle of the Drive housing engages, with guides in the form of mutually corresponding projections and grooves are provided on the dome-shaped components and the receptacle and a connecting element, the head of which is held in a recess in the mirror glass support, penetrates the dome-shaped components and the receptacle centrally and in connection with a spring element whose restoring force acts on the mirror glass carrier in the direction of the drive housing, engages.
- the connecting element is a plug-in pin, the shaft of which consists of two resilient legs which penetrate the drive housing and bear against the outer surface of the drive housing in a locking manner with a detent which is seated on its free end.
- a spring element in the form of a wire spring engages in the slot between the two resilient legs of the connecting element and is supported on both sides of the recess of the mirror glass support. This spring element bears against the underside of the head of the connecting element and thus exerts a restoring force which moves the mirror glass carrier in the direction of the drive housing.
- the head of the connecting element is without contact with the wall of the recess of the mirror glass carrier.
- this known coupling device has shortcomings. Since the connection between the mirror glass support and the drive housing - apart from the adjustment elements - is made solely by the wire spring, there is a risk that the wire spring will be bent if the rearview mirror is subjected to a sudden load. This results in at least one play in the coupling device, which makes the rearview mirror inoperable; in the worst case, the rearview mirror will be destroyed. In addition, the frictional forces between the coupling parts of this known coupling device are low, which favors disadvantageous vibrations of the rearview mirror. These low frictional forces are mainly due to the fact that there is only a line contact between the head of the connecting element and the mirror glass support via the wire spring, the combination of plastic and
- REPLACEMENT BLA ⁇ (RULE 26) Metal reduces friction. After all, inaccuracies in the shape of the spring - seen over the adjustment path of the mirror glass support - lead to different frictional forces.
- the invention has for its object to provide a coupling device for motor vehicle rear-view mirrors, which is impact or shock resistant and keeps vibrations of the mirror as low as possible by increasing the frictional force of the coupling parts, the frictional force in both adjustment directions of the mirror glass support and the entire adjustment path is the same.
- the connecting element is a threaded bolt, the free end of which penetrates at least one wall of the drive housing is provided with a nut,
- the surface of the nut facing the drive housing can be supported with a first region against the spring element and with a second region against the drive housing and
- the spring element is arranged in or on the drive housing.
- the feature lit. b the contact surfaces of the components which can be pivoted relative to one another are enlarged.
- the feature lit. d alone assigns the spring element the function of ensuring a defined frictional force; Influences on this function by other tasks such as securing of the hold, friction surface, axis of rotation and sliding axis, as in the case of the known coupling device, are therefore not to be taken care of.
- the mother of the feature lit. In interaction with the spring element, a causes the defined frictional force by the contact areas provided on the underside of the head of the threaded bolt against the surface of the recess of the mirror glass carrier and in interaction with the drive housing, the limitation of the spring amplitude and the protection against harmful effects of impacts or Bumps.
- An increase in the frictional force is achieved according to a further essential feature of the invention in that the dome-shaped projection of the mirror glass carrier, the dome shell and the receptacle of the drive housing are designed to lie flat against one another at least in regions.
- the threaded bolt has a slot which runs in the direction of its longitudinal axis and is open towards its free end and which is provided with an axially extending conical extension which opens towards the free end.
- a space is created for the passage of the spring element and for accommodating the first area of the nut acting on it.
- the conical widening causes the threaded bolt to spread when the first area is inserted, thereby securing the nut against unintentional loosening.
- the underside of the head of the threaded bolt is bulky. preferably spherical.
- the contact areas are enlarged with the surface of the recess of the mirror glass carrier. If, according to a further feature of the invention, the spherical surface is roughened, a further increase in the frictional force is achieved.
- the thread profile of the threaded bolt is expediently sawtooth-shaped. In conjunction with the aforementioned spreading of the threaded bolt, this results in an increased clamping effect in the threaded area.
- the shaft area between the head and thread of the threaded bolt have a reduced diameter.
- the passage opening in the recess of the mirror glass carrier can thus be kept small, so that there is sufficient area available for contact with the underside of the head of the threaded bolt.
- the nut assigned to the free end of the threaded bolt is cap-shaped, a pin projecting axially from the center of the underside of the cap roof.
- the end face of the pin forms the first region that can be supported against the spring element, while the lower cap edge represents the second region that can be supported against the drive housing.
- the pin is conical in its area adjacent to the cap roof and a cylindrical area adjoins this conical area, the conical area of the pin being slightly has a larger diameter than the conical extension of the slot of the threaded bolt.
- the threaded bolt and the nut expediently consist of the same plastic material, but the nut is reinforced with glass fiber.
- the uniformity of the material increases static friction, while the glass fiber reinforcement protects the pin against deformation.
- the spring element is designed as a double-sided spiral spring in the form of a straight round wire, which is positioned on the inside of the wall of the drive housing opposite the mirror glass support and inserted in two receptacles arranged at the ends . in front of which there is a locking element and a support as well as a groove for holding and supporting the spiral spring, the depth of the groove running below the spiral spring increasing towards the center of the spring.
- the spiral spring penetrates the threaded bolt.
- the surface areas located between the guides are roughened in whole or in part. As already mentioned above, this increases the frictional force. In the case of partial roughening, it is advisable not to roughen the area adjacent to the threaded bolt because this makes the least contribution to the frictional force; it also counteracts the ingress of dust and dirt from the outside.
- the further feature of the invention also aims in this direction, according to which the radii of the dome-shaped components are selected such that the roughened areas but not the non-roughened areas lie against one another.
- Fig. 5 is a longitudinal section perpendicular to the spring element through the coupling device according to the invention.
- FIG. 1 shows a threaded bolt 1, a mirror glass support 2, two adjusting elements 3, a spherical cap 4, a drive housing 5 and a nut 6 from bottom to top.
- FIG. 2 shows a housing shell 5a, a spiral spring 7, two drive motors 8, two corrugated rings 9, two ring springs 10, two drive wheels 11, two intermediate wheels 12 and a housing shell 5b from bottom to top.
- Fig. 3 shows the housing shell 5a with built-in spiral spring 7 and built-in drive 8 - 12.
- the spiral spring 7 runs between the two drive motors 8 parallel to their longitudinal axis; it is inserted at the end into a receptacle 13, in front of which there is a detent element 14 and a support 15 as well as a channel 16.
- the channel 16 continues in a centering and fixing socket 17.
- FIGS. 4 and 5 show the mirror glass carrier 2 with a recess 18 in which the head 19 of the threaded bolt 1 is located, one on its underside has spherical surface 20, which rests fully against the inner surface of the recess 18. Underneath the recess 18, the spherical shell 4 bearing against its outer surface can be seen, which in FIG. 4 with outer projections 21 in corresponding grooves 22 of a receptacle 23 provided in the housing shell 5a and in FIG. 5 with inner projections 24 in corresponding grooves 22 of the recess 18 engages.
- the recess 18 and the spherical cap 4 are penetrated with radial play by a threadless region 25 of the threaded bolt 1 with a reduced cross section.
- the threaded bolt 1 has a slot 26 which coincides with a longitudinal center plane and which is open towards the free end of the threaded bolt 1 and is provided with an axially extending conical extension.
- the free end of the threaded bolt 1 has a sawtooth thread 27.
- the spiral spring 7 runs through the slot 26 of the threaded bolt 1. This is acted upon by a pin 28 in the direction of the mirror glass carrier 2.
- the pin 28 protrudes from the center of the cap roof of the mother 6.
- the lower peripheral edge 29 of the nut 6 is held in the fully screwed-on position shown at a distance from a stop surface 30 of the drive housing 5, against which it only briefly comes into contact when the rearview mirror is impacted or struck.
- the distance between the lower peripheral edge 29 and the stop surface 30 is dimensioned such that the spiral spring 7 can only be bent in the elastic region.
