Definitions

  • the present invention relates to devices for controlling window regulators with electric motors in a motor vehicle.
  • each window regulator has associated therewith at least one relay connected between the electrical system of the motor vehicle and the motor of the window regulator in order to control the supply of working energy to the motor, and in that remote control units are provided comprising switches which are each connectible through low power conductors to the energisation circuit of one of the relays.
  • a device for controlling the electric window regulators of a motor vehicle having good reliability, efficiency, convenience and safety in use, due to the fact that the control of the window regulators is effected by currents of the order of a few milliamperes, which are the typical energisation currents of the relays.
  • Electrical conductors of reduced cross-section such as those generally called “low power" conductors, can therefore be used for connection to the control units of the window regulators.
  • the control of the window regulators by means of relays ensures that only the relay energisation current passes through the switches of the control units, avoiding any risk to their users.
  • high currents can be used to supply the motors of the window regulators, improving the characteristics -of speed and efficiency of operation of these motors.
  • the device according to the invention is characterised in that the motor of each window regulator has associated therewith a pair of relays for activating the motor in the directions of raising and lowering the window respectively, and in that the connection arrangement of these relays is such that the simultaneous operation of the control switches associated with both the relays of each pair causes the interruption of the supply to the motor.
  • a motor car generally indicated A, has front windows with which there are associated window regulator devices driven by electric motors indicated M (left-hand side) and M 2 (right-hand side).
  • Two control units are situated respectively within reach of the driver and the passenger occupying the front right-hand seat of the car.
  • Each of the units U 1 and U 2 is provided with four push buttons for controlling the operation of the motors M 1 and M 2 in two directions to effect raising and lowering of the front windows of the car A.
  • the push buttons which control operation of the motor M 1 acting on the left-hand window are indicated 1 and 2
  • the push buttons which control the operation of the motor M 2 associated with the front right-hand window of the car are indicated 3 and 4.
  • the four push buttons of the unit U 2 each of which duplicates the operation of a corresponding push button of the unit U 1 , are indicated 11, 12, 13 and 14.
  • Two relays preferably relays of the automotive type, which control the operation of the motor M 1 are indicated 5 and 6.
  • Two similar relays 7 and 8 control the operation of the motor M 2 .
  • a first bundle of low power cables connects the control unit U 1 to the energisation circuits 5a, 6a of the relays 5 and 6 ( Figure 2).
  • a similar bundle D 2 of low power conductors connects the second control unit U 2 to the energisation circuits 7a, 8a of the relays 7 and 8.
  • diodes 5b, 6b, 7b and 8b are connected in parallel with the energisation circuits of all four relays to protect the latter against reverse polarisations and overvoltages.
  • the two control units U 1 ,U 2 are connected together by means of a further bundle of low power cables, indicated D 3
  • the diagram of Figure 2 is substantially symmetrical about a horizontal line ⁇ .
  • the portion of the diagram above the line ⁇ shows the connections of those components of the device on the left-hand side of the car, while the portion of the diagram below the line illustrates the connections of those components of the device on the right-hand side of the car.
  • the diagram of Figure 2 is further subdivided into two parts, the first of which, shown on the left, has the low power components of the device, that is all the control components of the device which, in use, are passed through by modest currents of the order of milliamperes.
  • the part of the diagram shown on the right of the Figure includes the power elements, that is those elements which, in use, are passed through by the operating currents of the motors M 1 and M 2
  • the push button 1 of the unit U 1 and the push button 11 of the unit U 2 which are connected in parallel with each other, are disposed electrically in series with the energisation circuit 5a of the relay 5 in the connection arrangement of this energisation circuit to the poles P and N of the electrical system of the car.
  • buttons 2 and 12 which are in parallel with each other, are disposed in series with the energisation circuit 6a of the relay 6.
  • a similar connection arrangement is provided for the energisation circuit 7a of the relay 7 disposed electrically in series with the push buttons 3 and 13, which are connected in parallel with each other, and for the energisation circuit 8a of the relay 8 disposed electrically in series with the push buttons 4 and 14, which are connected in parallel with each other.
  • each relay may be effected equally well by one or other of the control units U 1 , U 2 .
  • the motor M 1 is connected between the relays 5 and 6, each of which acts as a switch able to connect one of the supply terminals of the motor M 1 selectively with the positive pole P or the negative pole N of the electrical system of the car.
  • the motor M 2 associated with the front right-hand window of the car is connected between the relays 7 and 8 each of which can connect one of the supply terminals of the motor with one or other of the poles of the electrical system of the car.
  • the motor M 1 is thus activated causing, for example, the raising of the window with which it is associated.
  • the push button 1 (or the push button 11) can be released to return the relay 5 to the de-energised state and cut off the supply of the motor M1
  • the same window may be lowered by operation of the push button 2 (or the push button 12) so as to energise the relay 6.
  • the motor M 1 is connected to the electrical system of the car and is rotated.
  • the polarity of the connection is however reversed with respect to that which can be obtained when the relay 5 is energised.
  • the motor M 1 thus rotates in the opposite direction, lowering the window associated with it.
  • the relays 5, 6,and the motor controlled thereby may have associated sensors (not illustrated) for causing the deactivation of the motor itself when the windows reach their upper and lower travel limit positions.
  • connection arrangement described is such that the accidental operation of a raising push button (for example the push button 1) and a lowering push button (for example the push button 2 or the push buton 12) acting on the same motor M 1 energises both relays 5 and 6.
  • a raising push button for example the push button 1
  • a lowering push button for example the push button 2 or the push buton 12
  • Both the supply terminals of the motor are thus connected to the positive pole P of the electrical system.
  • the motor is therefore not activated, avoiding accidental overloads and damage to its windings.
  • connection arrangement of the push buttons 3, 4,13 and 14 to the relays 7 and 8 is exactly the same as the connection arrangement of the push buttons 1, 2, 11 and 12 to the relays 5 and 6.
  • the push button 3 and the push button 13 allow the relay 7 to be energised in ordertto cause the raising of the glass of the front right- hand window of the car.
  • the push buttons 4 and 14 act instead on the relay 8 and allow lowering of this window.
