Definitions

  • the invention relates to an electromechanical actuating device which is driven by an electric motor by half a revolution in each case.
  • the known actuators for example fi use in central locking systems for motor vehicles, generally comprise an electronic control center which transmits the drive to all the actuators in the system, the precise stopping of the actuators in the rest position and the security against untimely actuation.
  • the conditions of use generally make these systems appear fragile, and in all cases their installation is costly and complicated.
  • the aim of the invention is to ensure the system's functions and safety features by means of electromechanical means which are accommodated in the actuating device itself, and to use the properties of the electromechanical means with regard to robustness, simplicity, functionality and economy.
  • object of the invention is an electromechanical actuator with renztourigem driven by electric motor, the umfdies t an electric motor for driving a gear which drives a control pin to back-and-fro movement at each half-rotation, characterized in that said toothed wheel with limited angular play fixed is connected to a drive wheel of the said pin and this drive wheel comprises a torque spring which tends to bring the gear wheel and the drive wheel back into a certain angular position, and the drive wheel also comprises a stop element which can be retracted into a certain angular position at the end of the working cycle; in this case, the tension of the torque spring induced by the abovementioned stop produces the retraction of the abovementioned stop member and the locking by the retractable stop member in a second specific angular position.
  • the gear wheel R (FIGS. 4 to 6) is offset via a bean-shaped opening 1 through which the protruding driver (d) of a second drive wheel E (FIGS. 7 to 11) passes - the drive wheel E rotates on the same axis A as the wheel R. , which partially covers the circumference of the wheel E - the wheel E in rotation, which in turn drives a locking slide C (shown in more detail in Figures 12 to 16) and also, as will be explained below, ensures safety of the successive attacks.
  • the driver d is supported sequentially depending on the starting position of the sequence, which is initiated by a return or exit position of the control pin T of the actuating device, either on the outer edge r 1 of the upper side relief r of the raised part r of the lower side relief r i of the sliding sole S des Sled C on this Is stimulated to a linear reciprocating movement, namely every half rotation of the drive wheel E equipped with the driver (d).
  • the wheel E carries on its outer circumferential edge, which is not covered by the wheel R, two diametrically opposite cut-in areas Cr 1 and Cr 2 , which are shown in further detail in FIGS. 8, 10 and 11.
  • the areas Cr 1 and Cr 2 each comprise incisions 1 and 2, which interact in sequence in the course of the sequential displacement with a V-shaped leaf spring R 1 with a curved apex (FIG. 17).
  • the ends of the spring R are supported in a seat 1 in the housing of the actuating device, while their rounded apex is elastically supported on the circumferential edge of the wheel E so that at the end of a sequence of these apices it engages in the incision 1 in the area Cr 1 or Cr 2 , which was diametrically opposed to him at the beginning of the episode.
  • the wheel E carries a torque spring R, the free ends of which approach each other in the course of the sequence under the joint action of an inner cam b 1 of the wheel R and an inner stop edge b 2 of the wheel E. If the wheel R stops, the spring R C instantaneously relaxes and exerts a return pressure on the stop b 2 of the wheel E, which causes an additional rotation of this wheel E until the apex of the spring R 1 passes from incision 1 to incision 2 of the incised area. In this effective and safe manner, the wheel E is stopped in a precise and stable position, which is determined by the incision 2.
  • the precise angular position of the wheel E causes a precise displacement of this carriage C and its control pin T in the return or exit position 'via the driver d, which sits between the drive joint edges r 1 and r 2 of the carriage C.
  • the wheel E carries on its back the circular contact track, divided into sectors S 1 and S 2 , each of which, depending on the angular position of the wheel E, cooperate with electrical grinding wheels F 1 - F 2 - F 3 , which are in the wall of the housing Actuating device are housed and the loop ends assume the positions shown in Figure 2.
  • This arrangement ensures that each work sequence that has been started is ended and that each precise stopping of the wheel E guides the live sectors of the contact track to only two of three grinding wheels, whereby the triggering of the next sequence depending on the position of the distributor contact C C -C T , which alternately connects the grinding wheels F 1 -F3 with the power supply line, is guaranteed.
  • the actuating device also includes means which make it possible to actuate the lock by hand if one of the electromechanical control parts fails, also for the functioning of other associated electromechanical locks, for example on a motor vehicle.
  • the pin T is mechanically mounted on the slide C in such a way that it acts on one or the other of these parts under the action of a greater longitudinal force exercised is elastically disengaged, which enables the electrical supply and power consumption, i.e. the functioning of further locks connected in parallel.
  • the control pin T is provided with an end piece 3, the width of which is selected such that it finds accommodation with gentle friction in a groove 3 'of the sole of the carriage C and can slide therein.
  • a leaf spring Rd ( Figure 21), similar to the spring R 1 , has its apex supported on the bottom of a longitudinal seat 4 of the pin T and engages in a notch 4 'of the groove 3' of the carriage C.
  • the carriage C-pin T assembly is thus stiffened for normal operation, but can be separated by elastic deformation of the spring Rd in the event of an abnormal force.
  • the two distribution contacts C c and C one located under the sole of the slide C, the other under the control pin T, slide on the fixed terminal area of each grinding wheel F 1 and F 3 to connect them to an electrical supply terminal A and a proper one Ensure current consumption in the sequential circuit.
  • This topic is referred to in FIGS. 22, 23 and 24.
  • the embodiment according to FIG. 37 enables total functional reliability to be obtained when the control pin T is displaced.
  • the track S carries a radial projection S 3 which , in the holding position (shown in the drawing), is in contact with an abrasive body F 4 which is responsible for the front actuator ACA and the rear actuator ACR is connected to a line L.
  • a grinding wheel F 5 diametrically opposite the grinding wheel F, is connected to a line L 2 .
  • a control grinding body F 6 connected to the opposite polarity (in the drawing -) with respect to that to which the motor M (in the drawing +) is connected cooperates with the circumference of the path S which has two diametrically opposite cutouts E 1 and E2, one of which one (in the drawing E 1 ) is in the stop position on the grinding wheel F 6 .
  • the motor M is connected to a grinding wheel F 7 , which is in constant contact with the web S.
  • control pin T switches the contacts F 5 and F 6 of the front actuating device ACA side by side, and the motors M of the two actuating devices are not supplied.
  • control pin T When the control pin T is actuated (dotted position in the drawing), it switches the grinding wheels F 4 and F 6 side by side, and the motor M of the front actuating device ACA is supplied.
  • the motor M of the rear actuating device ACR is also supplied via the line L 1 .
  • each motor M is no longer supplied and each actuating device stops in the correct position.
  • the drive is effected by a pulse contact CI, which acts on the terminals of the motor M of the front actuation device ACA.
  • the rear actuating device ACR is connected to only three lines.
  • the grinding wheel F 6 is not connected directly to earth, but to the grinding wheels F 4 and F5 via diodes D 1 and D 2 .
