Definitions

  • the invention relates to the attachment of elements of the sensor type intended to control functions, sensors which are placed behind automobile windows.
  • Typical sensors are intended to receive signals from outside the vehicle or monitor the operation of elements integral with this glazing.
  • To the first category belong the various antennas (radio, GPS, telephone ...), rain, light or similar detectors ...
  • To the second category belong the various systems capable of monitoring the operation of certain elements such as heating glazing, the control of electrical control means for controlling the light transmission.
  • the first condition is of course to fulfill their function satisfactorily by not disturbing that of the other neighboring elements, including the fundamental one of the windshield itself which must offer the best possible vision.
  • the sensors must be located in locations which not only guarantee that they can function satisfactorily, but also which do not reduce the visual field or introduce distortions thereof.
  • the sensors are preferably of dimensions as small as their function allows.
  • the invention relates to sensors bonded to glazing and in particular to automobile windshields. More particularly, the invention relates to sensors of the rain detector type or the like, for which the signals which they pick up are transmitted through the glazing. This implies that the sensor support does not come between the glazing and the sensor itself. For this reason, the supports are made up of elements located on the periphery of the sensor.
  • the fixing of these sensors was done according to the experience acquired for the fixing of the first elements which were fixed on the windshields, namely the bases of mirrors.
  • the fixing of the mirrors requires a particular resistance taking into account the efforts supported during use.
  • Each movement of the mirror subjects the base and its attachment to relatively large pulls.
  • the base on which the mirror base was fixed must therefore be particularly rigid. It also had to adhere to the glazing strongly and permanently.
  • Typical alloys are, for example, zinc-based alloys such as that known as "ZAMAC". Supports have therefore been produced in these materials to fix in particular the rain sensors. In practice, it turns out that current supports are largely unsuitable.
  • the surface available for sticking these supports to the glazing must be as small as possible. Most of the surface occupied by the sensor is obviously intended for the transmission of the signal received. In the initial embodiments, the sensor is most often fixed a surrounding or support frame, relatively narrow so as not to increase the total area of the sensor on the glazing. The limited surface area and the weight of the support mean that an insufficiently solid bonding is observed.
  • the invention proposes on the one hand to improve the constituents used as support for the sensors, and on the other hand, to simplify the operations of implementation of these supports and ancillary elements.
  • the sensor support of the rain detector type which requires placing the sensor so that it receives the signals through the glazing, consists of an element surrounding the sensor, closing continuously.
  • the support according to the invention thus formed has better dimensional rigidity although of relatively small section compared to its largest dimensions due to its closed shape.
  • a typical shape is that of a ring overall.
  • the support can be made of a less rigid material than that of the previous supports. Consequently, it is also possible, according to the invention, to lighten this support and, consequently, to have a bonding on the glazing also lighter. Taking advantage of these features, it is possible, if necessary, to constitute the support in the material of the chute. In this way it is still possible according to the invention to constitute in a single piece, the sensor support and the chute intended to receive the conductors. The grouping of several pieces in one, reduces the stocks referenced, and especially reduces the operations of installation on the glazing.
  • the well-known semi-rigid synthetic materials are generally suitable for constituting the supports according to the invention.
  • moldable materials are used. They have the advantage of being relatively easy to use, and like all polymeric materials, are much lighter than metal alloys, and do not raise any corrosion problem.
  • copolymers of the acrylonitrile-butadiene styrene type or any other moldable product leading to relatively rigid products are used.
  • the constituents are chosen to be of the same kind as those of other elements such as the chutes receiving the conductors. By choosing identical materials, it is possible to combine several elements in one piece.
  • FIG. 1 is a partial view of a windshield having a provision of the prior art for the establishment of a sensor
  • FIG. 1 is a plan view of a front sensor support
  • - Figure 3 is a plan view of a sensor support according to the invention
  • - Figure 4 is a plan view of a sensor support according to the invention, comprising a chute
  • - Figure 5 is a side view corresponding to the support of Figure 4.
  • the part of the windshield shown in Figure 1 is located in the upper and middle part, part which traditionally receives the base of the mirror. This part includes several areas coated with enamel intended to hide from the outside the elements fixed to the windshield. Where appropriate as shown, the enamel is placed in a first zone 1 continuously, excluding the reserves such as 2, to maintain the light transmission necessary for certain sensors such as that intended to detect rain. In this zone 2 there is no enamel. Zone 1 can be extended by one second, in which the enamel is applied discontinuously in the form of dots. This procedure is traditionally intended to mark a transition between the continuous zone 1, and the uncoated glass 4.
  • the glazing comprises layers of conductive type, it is possibly necessary to clear an area, as in 3, to guarantee the functioning of sensors operating on the basis of radiometric waves.
  • FIG. 1 the location of the mirror base is marked in 5..
  • the support of a traditional rain detector is shown in 6.
  • the support in question consists of an element which in this example is of incomplete annular shape.
  • the support 6 is glued to the windshield in the same way as the rear view mirror.
  • a chute 7 intended to receive the conductors of the sensor is also bonded to the windshield. Given the low mass of the chute and the conductors it receives, a lighter adhesive is often sufficient.
  • a double-sided adhesive material previously applied to the back of the chute, so that the installation of the chute consists of applying it on the windshield after removing the film that protects the adhesive attached to the chute.
  • the support 6 and the chute 7 are separated. They are made of different materials and applied separately.
  • the support 6 is made of a metallic alloy of "ZAMAC", an alloy based on zinc and less aluminum, and whose density is of the order of 6 g / cm 3 . This material apart from the fact that it is relatively heavy, is very rigid which guarantees that the support remains stable in dimensions even when the sensor is inserted to be clipped to it.
  • the chute is much lighter. It is formed from a U-shaped profile.
  • a typical material for the manufacture of the chute is a moldable polymer such as ABS material.
  • the lightness of the chute facilitates its attachment to the windshield. Possibly it is known to have parts on the walls of the trough in which, locally, the branches of the U are interrupted to facilitate the conformation of the trough to the curved profile of the windshield.
  • the support 6 and the chute are applied separately with a certain precision.
  • the sensor is then fixed on its support as indicated above, by clipping.
  • the conductors and the connector connecting the sensor to the control members are then put in place.
  • Finally the assembly is covered with a cover which conceals the sensor, the sensor support, the chute and the electrical conductors inside the vehicle.
  • the cover is usually made of the same material as the chute, and is clipped onto the latter and onto the sensor support.
  • the sensor support of the prior art is shown in Figure 2 on the side which is applied to the windshield.
  • This support comprises an annular band 8 delimited inwards by a rib 9.
  • the provision aims on the one hand to avoid uneven crushing of the bead of adhesive which is applied to the band 8, and on the other hand, prevents the glue overflowing inward in areas of the windshield not coated with enamel.
  • the rib is relatively low. A few tenths of a millimeter is a usual measurement.
  • the support also includes a rebate 10 set back relative to the plane of the strip 8, a rebate on which the sensor rests. The latter is still centered by means of the studs 11 which ensure precise positioning on the glazing.
  • the support shown in Figure 3 is of similar construction to that of the traditional support with regard to the provisions relating to the fixing on the glazing, and those of fixing the sensor.
  • the ends of the annular support are joined by a bridge 12 whose shape is partly determined by that of the connector which is connected to the sensor. In the form presented, this leads to spreading the connection part from the annular part proper. This part 13 is carried beyond the connection area under the conductors.
  • the presence of the bridge 12 according to the invention makes it possible to use a support made of a material having less rigidity than that of the previous supports not having the risk of seeing the ends of the annular support move apart.
  • FIG. 4 shows an embodiment of the support of the previous type, in which the chute intended to receive the conductors is in one piece with the part receiving the sensor.
  • Figure 5 shows how these two parts are brought together.
  • the chute has parts on which it is composed only of the sole 15 resting on the windshield.
  • the same type of connection 16 is made between the body of the sensor support and the chute, giving the assembly the desired flexibility.
