- the sensor 16 or the magnet 14 is driven by the motor shaft 12.
- Figure 1 shows, without limitation, the magnet 14 mounted on and driven by the motor shaft 12.
- the magnet 14 presents to the sensor 16 an alternation of poles 15 North and South as a function of the relative position, angular and along the axis 13 of the sensor 16 and of the magnet 14.
- the magnet 14 presents to the sensor 16 an alternation of poles 15 which is specific to the relative position of the magnet 14 and of the sensor 16.
- the device 10 can also include a housing 11 in which the motor shaft 12 is rotated about the axis 13 and is movable along d e this axis 13.
- the motor shaft 12 is for example rotated by an electric motor 20.
- the electric motor is in two directions of rotation.
- the motor shaft 12 is movable along the axis 13 along the arrow 18 in the sense that the motor shaft 12 is mounted in the casing with a mounting clearance. This play allows a displacement of the motor shaft 12 along the axis 13 during the drive of the shaft by the electric motor 20.
- the position along the axis 13 of the shaft 12 can be determined by detection of the alternation of poles 15 of the magnet.
- the sensor 16 makes it possible to detect the poles that the magnet 14 presents to it.
- the sensor makes it possible to determine which pole 15 presents the magnet 14.
- the sensor 16 makes it possible to determine the change of pole 15 presented to the sensor 16.
- the sensor 16 is a Hall effect sensor.
- the sensor 16 is in the casing 11.
- the sensor 16 being fixed in the casing 11, this makes it easier to connect the sensor 16 to a signal processing device of the sensor.
- the magnet 14 is multi-pole. According to the example in FIG. 1, the magnet 14 is driven by the shaft 12. The dotted lines show another position of the magnet when the shaft 12 is moved along the axis 13.
- FIG. 2 shows a perspective view of the magnet 14.
- the magnet 14 may be a ring driven in rotation by the motor shaft, the ring having in its thickness the poles extending radially. This allows the magnet to be easily mounted on the shaft 12. The thickness of the magnet is for example 5mm.
- the magnet 14 has an axis of symmetry 13, around which the shape of the rotating magnet is invariant. The axis of symmetry of the ring and the axis of rotation of the motor shaft 12 can advantageously be the same.
- the magnet 14 has a plurality of poles 15.
- the poles alternate, during a rotation around an axis 13 of symmetry and at the height of a plane P perpendicular to the axis 13, as a function of the position along the axis 13 of the magnet 14.
- l 'alternation of poles varies with respect to the plane P.
- the poles 15 have converging flanks 22.
- the border between two consecutive poles is inclined relative to the axis 13 and therefore relative to a displacement along the axis 13.
- the magnet 14 comprises two flanges 24, 26 coaxial with the axis 13.
- the poles 15 extend towards the other flange, each pole 15 of a flange being interposed between two poles 15 of the other flange.
- the poles having inclined flanks 22, the poles 15 form a toothing on the flanges 24, 26.
- the flanges 24, 26, provided with their respective poles are separable from one another. This makes it easier to manufacture the magnet, each of the flanges and their respective poles being able to be manufactured separately and then assembled to the other flange.
- the flanges 24, 26 are for example made of magnetic material such as steel or soft iron and the poles made of magnetizable material such as steel or soft iron. In this way, the magnetic flanges, more fragile, are easily manufactured, while the poles, more difficult to machine, are made of a more solid material.
- the poles are fixed on the flanges.
- the flanges are each of a different polarity, and the poles made of a magnetizable material, acquire the nature of the polarization of the respective flange. In FIG. 2, the flange 24 is polarized South; the corresponding poles are South.
- the flange 26 and the respective poles 15 are polarized North.
- poles 15 and the flanges 24, 26 are made of magnetizable material such as steel or soft iron. Thus these parts are made of a more solid material; the machining of the parts is thus easier.
- Figure 3 shows a side view of the magnet 14.
- the poles 15 are contiguous.
- the poles 15 have opposite sides 22 inclined with respect to the axis 13.
- the poles 15 have for example a triangular cross section. This allows them to be easily interposed with the poles of the other flange, the top of one pole of a flange being inserted between the base of two poles of the other flange. The angle at the top depends on the number of poles and the shape of the polar masses.
- the cross section can also be trapezoidal.
- the poles of one flange are isolated from the poles of the other flange.
- the insulator 28 is interposed between the sides 22 of the poles 15.
- the insulator 28 allows ! better detection of change of poles by the sensor 16.
- the insulator is for example air or a non-magnetic material such as plastic or copper.
- Figure 4 is a graph of detection of the alternation of the poles 15 of the magnet 14 by the sensor 16 in the device 10.
- Figure 4 shows a side view of the magnet 14 according to Figure 3.
- the two flanges 24 and 26, respectively polarized South and North, have the poles 15 which extend between them.
- the poles have the polarity of their respective flange.
- the sensor 16 is shown in different relative positions A, B, C relative to the magnet 14, according to the movements along the axis 13 of the motor shaft 12.
- the magnet 14 or the sensor 16 is driven by the tree. In the example which is described, the magnet 14 is driven by the shaft 12 and the sensor 16 is in the casing 11.
- Positions A and C correspond to extreme advancement or retraction positions of the shaft 12 along the axis 13 in the casing 11.
- Position B is an intermediate position of the shaft 12.
- the lines referenced 30a , 30b, 30c represent the passage of the poles 15 of the magnet 14 in front of the sensor 16 during the rotation of the shaft 12 around the axis 13.
- the positions A, B, C represent the mobility of the shaft along the axis 13 (arrow 18 in Figure 1) and the lines 30a, 30b, 30c represent the rotation of the shaft 12 around the axis 13 (arrow 17 in Figure 1).
- Also shown in FIG. 4 is the detection by the sensor 16 of the poles 15 which appear in front of the sensor 16.
- the signal is for example a square signal which indicates a state "0" when a north pole is detected and which indicates a state " 1 ”when a South Pole is detected.
- the signals Sa, Sb, Se represent the detection by the sensor 16 of the alternation of the poles which appear to it according to the different positions of the shaft 12. According to the relative position A, B, C, of the sensor 16 relative at magnet 14, the passage times of the North and South poles in front of the sensor 16 are different.
- the sensor 16 In position A, the sensor 16 is close to the South polarized flange 24. In this position, and due to the convergence of the sides 22 of the poles, the sensor 16 is at the height of the base of the South poles of triangular section, and at the height of the vertices of the North poles of inverted triangular section. Thus, the time of passage of the South poles in front of the sensor 16 is longer than the time of passage of the North poles in front of the sensor 16. This results in a signal Sa indicating a state mainly "1" interspersed with brief passages to the 'state' 0 '.
- the sensor In position B, the sensor is approximately halfway between the flange 24 polarized South and flange 26 polarized North.
- the sensor 16 is located halfway up the North and South poles.
- the transit times of the South and North poles in front of the sensor 16 are substantially the same. This results in a signal Sb indicating states "0" and "1" of similar durations.
- the sensor 16 In position C, the sensor 16 is close to the North polarized flange 26. In this position, and due to the convergence of the sides 22 of the poles, the sensor 16 is at the height of the base of the North poles of triangular section, and at the height of the vertices of the South poles of inverted triangular section. Thus, the time of passage of the South poles in front of the sensor 16 is shorter than the time of passage of the North poles in front of the sensor 16. This results in a signal Se indicating a state mainly "0" interspersed with brief passages to the 'state' 1 '.
- the square signals Sa, Sb, Se are different, which indicates a different detection by the sensor 16 of the poles according to the relative position of the magnet 14 and the sensor 16.
- the repeated succession of the poles in front of the sensor does not occur from the same way depending on the relative position of the sensor and the magnet.
- the magnet 14 alternates with the sensor 16 of different poles according to relative A, B, C positions.
- the gearmotor can further comprise an output shaft 32 (FIG. 1) driven by the drive shaft 12.
- the drive shaft 12 is for example provided with a worm screw 34 driving a wheel 36 carrying the output shaft 32.
- It may for example be a window regulator motor.
- the window regulator also includes a cable winding drum or a mechanical arm.
- the output shaft drives the take-up drum or the arm.
- the device 10 makes it possible to determine the torque applied to the output shaft 32 by determining the axial movement of the motor shaft 12. In fact, according to the torque applied to the output shaft, the drive resistance of the wheel 36 by the shaft 12 is more or less large. This results in an axial movement of the motor shaft 12 in the casing 11 whose position along the axis 13 is determined by the device 10.
- the device 10 allows the torque at the output of the gearmotor to be determined simply and quickly. The output torque of the motor results in an axial force on the axis of the motor shaft.
- the device 10 can for example be implemented in the window regulator motor so as to detect the pinching of an object by a window.
- the torque applied to the output shaft of the window regulator increases. This results in the displacement of the motor shaft along its axis of rotation.
- the device 10 makes it possible to measure this displacement and to give the order to interrupt the drive of the window. This is also applicable for detecting the limit switches of the window.
- FIG. 5 shows another embodiment of the magnet 14.
- the magnet has the flanges 24, 26 and the poles 15 enveloping a magnetic core 38.
- the poles 15 and the flanges 24, 26 are made of magnetizable material; the magnetic core 38 allows the magnetization of the flanges and poles. The presence of the core 38 allows the magnetization of the flange and the poles in a lasting manner.
- Each of the flanges 24, 26 can be machined directly with poles 15 which extend from the flanges along the axis 13.
- Each of the flanges is in one piece with the poles which extend along the axis 13, from the flanges . This makes it possible to manufacture the magnet in the form of a ring more easily and less expensively. In particular, this avoids the machining of a magnetic material, or the assembly of magnets around a ring, which is long and expensive.
- Each of the flanges provided with its poles forms a half envelope; the magnetic core 38 is thus enveloped by two half envelopes which fit into one another.
- Figure 6 shows a half envelope;
- Figure 6 is a top view of Figure 5. It shows the flange 24 with the poles 15 distributed over its circumference.
- the flanges and poles give the magnet a ring shape, with a hole 48 for passage of the motor shaft.
- the poles 15 thus delimit a housing for the core 38.
- the poles can be distributed regularly around the circumference of the flange 24; the poles 15 are angularly spaced allowing the interposition between them of the poles 15 associated with the other flange 26.
- the other half-envelope is reversed on the half-envelope of FIG. 6, the poles of each half-envelope alternate and the flanges rest on the core 38.
- the core preferably has a North pole and a South pole along the axis 13.
- the flanges 24, 26 each rest on a pole of the core 38, each of the flanges acquiring the polarity of the pole with which it is in contact. .
- Each of the flanges transfers its acquired polarity to the poles 15, each of the envelopes thus being polarized differently. Two magnetizable half-envelopes are thus produced, machining being facilitated by the use of material more solid than that of the core.
- FIG. 7 shows a detail of the magnet 14. In this figure are represented two poles
- the pole 154 is for example South and the pole 156 is for example North.
- the space between the poles 154 and 156 can be occupied by the insulator 28.
- the sensor 16 detects the alternation of N and S poles.
- the poles 154 and 156 are connected by their base 40 to the flanges 24 and 26.
- the poles 154, 156 have an inclined plane 42 extending from a front 46 to a stud 44.
- the stud 44 allows the sensor to better detect the alternation of poles.
- the post has a width transverse to the axis 13 which allows the sensor 16 to detect the presence of a pole 154 South between two poles 156 North, while the magnet 14 is rotated at high speed.
- the sensor is more or less close to one or the other of the bases 40.
- the poles 15 have flanks 22 facing each other in the form of a broken line, the ends of which (the pins 44 and front 46) extend parallel to the axis 13.
- the line 30 corresponds to the detection by the sensor 16 of the alternation of poles which presents itself to it; the line corresponds to one of the lines 30a, 30b 30c of FIG. 4, the line 30 varying in position along the axis 13 according to the load applied to the motor shaft.
- the position shown corresponds to the relative position of the drive shaft relative to the sensor 16, when the drive shaft is idling without load.
- the latter varies in position along the axis 13, the sensor 16 being for example at a higher position along the axis 13 in FIG. 7.
- the sensor offset In the rest position, it is preferable to position the sensor offset along the axis 13 in the direction of one of the bases 40 of the poles 154 or 156, so that when loaded, the sensor 16 shifts towards the mid-height of the poles.
- the offset of the position of the sensor 16 towards the mid-height of the poles 154, 156 is caused when the window is driven upward.
- the line 30 is more halfway up the poles 154, 156.
- the line 30 is along the inclined plane 42, for example along the plane 42 of the pole 154. When the window is raised, the line oscillates along the plane 42 of the pole 154.
- the sensor 16 better detects movement of the shaft; indeed along the plane 42 and whatever the height along the axis 13, the sensor 16 detects the pole 154 over a shorter or longer time, which indicates the movements of the shaft, and of a possible pinch. This is due to a width of the pole 154 or 156 transversely to the axis 13 which varies along the inclined plane 42, which is not the case at the height of the front 46 or of the tenon 44. This allows more detection precise pinching through the glass of an object such as a finger.
- the probe 16 can be bistable (latched). It passes to state 1 in front of a south pole (for example) and must pass in front of a north pole to switch to state 0.
- the probe 16 is placed on line 30.
- Line 30 moves along plane 42 in function of the motor output torque. Due to the shape of the polar masses 156 and 154, the time tl for the passage of the north pole and the time t2 for the passage of the south pole in front of the probe, varies according to the position of the line 30 on the plane 42.
- we can calculate the ratio tl / t2 or tl / (t2 + tl) or t2 / (tl + t2). This ratio is called the duty cycle of the signal generated by the hall sensor 16.
- the duty cycle varies as a function of the position of the curve 30 on the plane 42.
- the position of the curve 30 is a function of the output torque of the engine
- the duty cycle of the signal from probe 16 is a function of the motor output torque. Consequently, if an obstacle appears during the raising of the window, there will be a variation in torque which will result in a variation in the duty cycle of the signal.
- the present invention is not limited to the embodiments described by way of example.
- the magnet with multiple poles could be replaced by a ring with surfaces having different reflecting characteristics and the sensor used could be an optical sensor. It is also conceivable that the magnet has empty spaces, the sensor detecting either the presence of a pole or the absence of a pole.
