Definitions
- the invention relates to a movable wheel control device used in automobiles as a digital control interface.
- the multiplicity of commands to which the driver of a modern vehicle has access is such that many interfaces are developed to activate functions without having to look at the command or his hands.
- the user relies on digital feeling to control a function and can stay focused and keep their eyes on the road.
- the control of many functions, including the navigation system, the radio, the telephone and all telematic functions, as well as the control of ventilation and air conditioning, is achieved through a control screen and a remote interface.
- the most recently developed navigation interfaces are directional wheels placed on the center console between the front passengers of the vehicle.
- Figure 1 illustrates in an orthogonal reference, longitudinal axis also called “front-rear”, transverse axis also called “right-left” and neutral axis, also called “vertical”, the possibilities of movement models with four degrees of freedom: longitudinal displacement front-back, right-left transverse displacement, main rotation by turning the wheel on itself and, to validate its choice the user can press the wheel which sinks slightly like a touch computer keyboard.
- the movements of directional wheels for vehicles have very small amplitudes limited to a few millimeters or less.
- the movements must be safe and precise so that the user focused on driving selects and validates easily and without error the function he is looking for.
- a return means constantly urges the wheel to a neutral position, generally central.
- the front-to-back and right-left movements of the wheel therefore require a light and pleasant effort necessary to overcome the recall.
- the rotation of the wheel is accompanied by a small cyclical effort felt by the user.
- Smartphones require in their cars interfaces that are simple, precise and flexible, that are caressed and return imperturbably in an immutable neutral position. The important restoring forces are no longer appreciated and the slightest inaccuracy in returning the wheel to the neutral position is an unacceptable defect.
- Figure 2 shows the kinematics currently the most optimized for devices whose wheel has four degrees of freedom presented before.
- An electronic card equipped with the circuits, switches and sensors necessary for the control of the functions is fixed at the bottom of a fixed box.
- the sensors are conventionally arranged under protective elastic domes which also serve to generate the return forces necessary for the return of
- the wheel in the neutral position, under the wheel, the mechanical part is organized around a pivoting shaft which extends along a main axis and whose lower part, close to the base, is in ball joint connection against a central sensor.
- the wheel In the absence of biasing the wheel is placed in neutral position in which the main axis coincides with the neutral axis and the wheel is in the up position, not supported.
- the displacements of the wheel being of small amplitude, the angular deviations of the main axis with the neutral axis are also very weak.
- a pivoting plate is arranged in sliding connection with the shaft so as to be driven by it during rotations and pivoting but not when pressing on the wheel. Longitudinal and transverse pivoting of the shaft and the plate cause longitudinal and transverse sensors to be switched via vertical actuators. On the other hand, during the main rotation of the wheel, the plate rotates but without acting on the actuators or the sensors. These, solicited vertically by the elastic domes rub slightly against the plate they solicit towards the top of the housing. These first parasitic friction, even slight, are the main source of disruption of good operation of the device. Furthermore, the plate is the upper part of a universal joint called "high-gimbal", whose lower part called “low-gimbal” is pivotally connected along the neutral axis with the base and the housing.
- the low-gimbal can be held in the housing by at least three flexible vertical uprights and defining a cylinder of revolution of neutral axis of a radius adjusted to that of the lower gimbal. Each amount is terminated by a lug directed towards the neutral axis so as to fall just above the lower gimbal when it is in place.
- the low-gimbal is radially held in place by the uprights and vertically by the lugs.
- the main rotation of the wheel rotates the shaft, the plate and the high-gimbal around the main axis and the low-gimbal around the neutral axis.
- the plate urges the low-gimbal upwards which rotating on the neutral axis rubs against the holding pins, or any other device now vertically down -cardan.
- the device is further provided with a discrete means of indexing the rotation.
- a discrete means of indexing the rotation During rotations, an index biased by a spring against a notched crown provided in the lower gimbal moves notch notch.
- the index When the rotation is stopped, the index must stop and position the wheel with precision.
- the parasitic friction explained above disrupts the positioning of the index and the device stops while the index is not on the screen not at the bottom of a notch.
- the wheel stops in an unstable position.
- the slightest solicitation then causes a small displacement of the wheel bringing the index to the bottom of the notch. This causes an inappropriate displacement of a cursor on the control screen and this positioning blur related to parasitic friction of the mechanical part is now unacceptable.
- the present invention solves the aforementioned problems by providing a mechanical control device whose internal friction has been minimized so as to bring the greatest satisfaction to the user.
- the device according to the invention is intended to select and select functions in a vehicle and comprises a manipulable wheel.
- the wheel is secured to the end of a shaft extending along a main axis.
- the wheel may be in a neutral position, the main axis coinciding with a fixed neutral axis, or may be displaced in at least one direction orthogonal to the neutral axis, the shaft being then rotated and the main axis inclined by relative to the neutral axis.
- This directional displacement is detected by at least one directional sensor.
- the wheel and the shaft can rotate about the main axis and this main rotation is detected by a rotation sensor.
- the sensors being connected to a steering unit of the vehicle functions.
- the device further comprises a directional switch connected to the shaft, the contactor extending from the shaft to a distal zone of action in said at least one orthogonal direction. The distal zone cooperates with the directional sensor so that pivoting of the shaft rotates the switch and distal zone actuates the directional sensor.
- the device is also provided with a discrete means of indexing the main rotation linked in rotation with the shaft. The means determines a plurality of stable positions of immobilization of the wheel. This has the double advantage on the one hand
- the directional contactor and the shaft are pivotally connected along the main axis so that the main rotation of the wheel and the shaft does not cause the directional contactor to leave it immobile without friction. between the distal zone and the directional sensor.
- the absence of friction advantageously ensures that the immobilization of the wheel at the stop of said main rotation is in one of the stable positions determined by the discrete means of indexing.
- the device is further provided with means for returning the wheel to the neutral position.
- the return means permanently exerts on the directional contactor a restoring force which, during directional displacements, is oriented in a direction opposite to the pivoting and which, in neutral position is oriented along the neutral axis.
- the pivot connection between the directional contactor and the shaft is pivot-sliding type isolating the discrete means of indexing said restoring force.
- this pivot-sliding connection only the radial component of the restoring force, component perpendicular to the main axis, acts on the shaft to oppose pivoting, the component along the main axis is only to it not transmitted to the tree and therefore not either by means of discreet indexing. This has the advantage of not creating additional parasitic friction at the indexing means and therefore to confirm that following a main rotation the wheel stops in one of the stable positions determined by the discrete means of indexing.
- pressing the wheel along the main axis translates the wheel and the shaft.
- This translation is detected by a validation sensor.
- this feature can advantageously enable the validation of a function.
- the shaft is slidably connected along the neutral axis with the discrete indexing means, so that, advantageously, the directional contactor and the discrete indexing means remain stationary when the wheel is seated on the wheel. pressing on the wheel being transmitted neither to one nor to the other.
- the means for returning the wheel to the neutral position is completed to permanently exert on the shaft another restoring force which opposes the translation and urges the shaft and the wheel to a high position corresponds to the neutral position.
- the neutral position is the position in which not only the main and neutral axes are merged but also the wheel and the shaft are pushed relative to the pressed position.
- the sliding and pivot-sliding connections isolate the shaft from the discrete means of indexing and the directional contactor and therefore from any force oriented along the main axis. Said other restoring force is therefore without influence on the directional contactor and on the indexing means and therefore
- the directional and validation sensors are electrical switches integrated into an electronic control board.
- the switches each comprise an elastically deformable dome made of elastomer in which are arranged an electrically conductive mobile pellet integral with the top of the dome and a fixed electrical conductive pellet integral with the electronic control board.
- the dome being not deformed, the pellets are moved away from each other and the corresponding control circuit is open, and active, the dome being deformed, the pellets are in contact with each other. other said corresponding control circuit being closed.
- the deformation of the dome generates a biasing force opposing the deformation.
- the shaft consists of a low section and a high section articulated with each other by a transmission joint such as a universal joint.
- the lower section extends along the neutral axis in conjunction with the discrete indexing means and the upper section extends along the main axis in connection with the directional contactor, the wheel being attached to the end of the section. high.
- the transmission joint is advantageously independent of both the directional switch and the discrete indexing means, so that the main rotation of the wheel causes the rotation along the main axis of the upper section as well as the rotation along the axis neutral of the low section and the discreet means of indexing and leaves the directional switch still.
- the directional displacement of the wheel causes the pivoting of the upper section and the directional contactor, the low section and the discrete indexing means remaining stationary.
- the device may further be provided with a translation limiter limiting to the neutral position the possibility of translation of the wheel and the shaft.
- the discrete indexing means of the main rotation comprises an index biased by an elastic means such as a spring, against a notched indexing wheel, the wheel, respectively the index, being arranged in pivot connection along the axis neutral.
- the positioning of the index at the bottom of a notch determines an angular position of stable immobilization of the wheel.
- the wheel thus has as much stable immobilization position as the wheel is provided with notches.
- the main rotation of the shaft drives the indexing wheel, respectively the index, in rotation according to the neutral axis, the index then moves notch notch relative to the wheel and, when stopping said main rotation the index is naturally positioned at the bottom of a notch thus immobilizing the wheel in a stable position .
- the device may be provided with a rotation limiter limiting the possibility of rotation of the wheel to the neutral position.
- the shaft may for example extend through a cross-shaped opening limiting to the branches of the cross the directional movements of the wheel.
- the device may be such that the wheel can be moved orthogonally to the neutral axis in four directions corresponding to the two opposite orientations of two distinct directions, for example a longitudinal direction, also called front-rear and a transverse direction, also called right left.
- the directional switch of such a device extends in the four directions, front, rear, right and left, up to four co-operating distal zones, front, rear, right and left, each with a directional sensor, front, rear, right and left, so that the movement of the wheel in any one of the four directions, front, rear, right or left, rotate the switch and the corresponding distal zone, front, rear, right and left, actuates the directional sensor corresponding, front, back, right and left, in the direction of movement.

- the invention described is a control device 10 for selecting and selecting functions in a vehicle, these operations being performed by manipulating a movable wheel 12 located outside a fixed housing 14 located in a tri-axis orthogonal coordinate system. direct, longitudinal axis L, transverse axis T and neutral axis N.
- the wheel 12 is fixed to the end of a shaft 16 extending along a main axis P which can be coincident with the neutral axis N, and then the wheel 12 is said PN neutral position, or spaced from the neutral axis N, the wheel 12 has been moved to any position.
- a “bottom” orientation “up” such as along the neutral axis N of the figures can be used, the wheel 12 being at the top of the device 10.
- the directions “right-left” and “front-rear” respectively can designate the directions along the transverse axes T and longitudinal L.
- the terms “high”, “low”, “above”, “below”, “higher”, “Lower”, “right”, “left”, “forward”, “rear” and “horizontal” and “vertical” may serve the description without limiting the scope of the invention in particular in relation to the many possible facilities of the device in the vehicle.
- the kinematic connections between the parts will be described respecting for the denomination and for the representation in the figures the standard NF EN 23952 / ISO 3952-1.
- the possible displacements of the wheel 12 has four degrees of freedom which are a transverse movement, or right-left, DG, corresponding to a pivot about the longitudinal axis L, a
- the front-rear movements AA and left-right DG are very small amplitudes too, although actually corresponding to pivoting, these movements can be perceived as small translations.
- the vertical movement TP is of very small amplitude, equivalent to the depression of a computer keyboard key. Only the main rotation RP can be of great amplitude, even may not be limited, the wheel can rotate indefinitely around the main axis P.
- the wheel 12 has the four degrees of freedom shown above.
- the invention can also be applied to devices that do not include all these possibilities, in particular not having the translation support, the validation of a function being done for example by pressing a separate button, or having no only longitudinal and not transversal displacement.
- FIGS. 3 and 4 The kinematics of the control device according to the invention is represented by FIGS. 3 and 4.
- This device 10 enables a user who manipulates the wheel 12 to act on functions of the vehicle. It is common, but not essential, that the movements are independent of each other and can not be combined.
- displacements is to limit the number of possibilities and thus to avoid errors to the user.
- Various means known to those skilled in the art are implemented to limit or even prohibit these combinations of displacement.
- an opening 18 in the form of a cross which limits the movements of the wheel 12 to the branches of the cross.
- a fixed indentation in the casing 14 which, in the neutral position, is remote from a movable indentation integral with the wheel 12, the two indentations interlocking as soon as the wheel 12 is moved, the meshing thus preventing the rotation of the wheel 12 inclined positon.
- a slight hollow in the housing 14 marking the location of the neutral position PN hollow in which one can press the knob 12, the surface of the housing rising slightly, but sufficiently around this neutral position PN and so prohibiting the translation of the wheel 12 combined with a displacement.
- the support on the wheel which causes a vertical translation TP and the main rotation RP of the wheel 12 can be done only when the wheel 12 is in the neutral position PN, the main axis P coincides with the neutral axis N.
- the main rotation RP will remain so called during the description.
- the control device 10 is fixed on a base 20 which can be either the horizontal bottom of the housing 14 on which is arranged an electronic card or a printed circuit, or directly the electronic card, or the printed circuit.
- On the electronic card 22 are provided switches and sensors 24, electrical or optical or any other technology, necessary for detecting the movements of the wheel 12 and the transmission of corresponding orders.
- Each sensor 24 is placed under an elastic dome 26 made of elastomer which on the one hand protects the sensor 24 and on the other hand exerts a force F1 opposed to any deformation imposed on it.
- the sensors are
- a switch is formed by arranging face to face within the dome, a mobile chip secured to the top of the dome and a fixed chip integral with the electronic card.
- the two pellets are made of an electrically conductive material such as copper or another metal. Pressing the dome deforms the pads into contact and closes an electrical control circuit. By stopping to press the dome, it returns to its original shape, and then the switch switches opening the control circuit, the mobile chip moving away from the fixed chip. It therefore appears that in this embodiment the elastomer dome is an integral part of the switch.
- the housing 14 fixed on the horizontal base 20 is provided with an upper opening 18 from which the shaft 16 emerges.
- the shaft 16 comprises an upper part 28, the upper shaft, which extends along the main axis P, and a lower part 30, the lower shaft, which extends along the neutral axis N.
- the upper shaft 28 and the lower shaft 30 are connected to the to one another by means of a universal joint type transmission joint 32 so that in neutral position PN, as in FIG. 3, the high shaft 28 and the low shaft 30 are aligned and the main axes P and neutral N coincide and that, following the longitudinal displacement AA of the wheel 12, as in Figure 4, the high shaft 28 is inclined and the main axis P away from the neutral axis N while the lower shaft 30 remains along the neutral axis N.
- the upstanding shaft 28 is connected to a directional switch 34 extending perpendicularly to the main axis P from the top shaft 28 to four distal zones of action 36: 36A front and 36B rear aligned along the longitudinal axis L and right 36C and left 36D aligned along the transverse axis T.
- the wheel 12 is limited to movements along the front-rear directions AA and right-left DG and a contactor 34 Cross-shaped with four perpendicular branches is therefore appropriate.
- the distal zones of 36A front, rear 36B, right 36C and 36D left, are in the vicinity of the ends of the corresponding branches.
- the contactor may also have the shape of a cross with more or less than four branches, or even the shape of a circular plate, the distal zones of 'action being in this case indistinctly integrated in the plateau.
- the contactor 34 is provided with an orifice 38 through which the upper shaft 28 extends in pivot-sliding connection LPG along the main axis P.
- the orifice 38 of the contactor 32 is in the center of the cross with four branches.
- the transverse and longitudinal pivoting of the shaft 16 therefore rotate the switch 34 while the main translation TP and the main rotation RP do not move it.
- a pivot-sliding connection LPG is currently carried out by means of two coaxial revolution cylinders, male for the high-shaft 28 and female for the orifice 38, whose diameters are adjusted so that the shaft can be easily inserted into the hole and that it can slip and run smoothly.
- actuators 40, 40A front, 40B rear, right 40C and 40D left extend vertically each between a dome 26 capping a direction sensor 24 respectively right front 24A, rear 24B, right 24C and left 24D, and the distal zone d 36, 36A, 36A, rear 36B and 36D left, of the switch 34.
- the switch 34 pivots around the longitudinal axis L, the rear distal zone 36D of the contactor 34 lowers and bears on the rear actuator 40D, the bottom of the rear actuator deforming the rear dome 26D and actuating the rear sensor 24D.
- the contactor 34 is similar to a rudder making it possible to transform the small horizontal displacements of the upper shaft 28 into vertical displacements. thanks to the large lever arm of the 34 contactor arms.
- the domes 26 constitute a return means 42 in the neutral position PN of the device.
- the actuators 40 are a little longer than the space in which they are placed between a dome 26 and the contactor 34.
- the domes 26 act very slightly on their respective actuators which exert on the switch 34 a vertical force Fl directed upwards.
- the LPG pivot-sliding connection between the contactor 34 and the shaft 16 isolates the shaft and then ensures that this vertical force Fl is not transmitted to the shaft.
- the lower shaft 30 In the vicinity of the base 20, the lower shaft 30 is in slide connection LG along the neutral axis N an indexing wheel 44 provided with a low central orifice 46, itself in pivot connection PV according to the neutral axis N with the housing 14.
- a sliding link LG is easily made by means of two cylinders, male for the low-shaft 30 and female for the indexing wheel 44, of complementary sections but not circular, for example sections cross, star, or square. The sections are adjusted so that the low shaft 30 can be easily inserted into the hole 46 of the indexing wheel 44 and can slide smoothly there but can not rotate freely.
- the lower shaft 30 passes through the bottom central orifice 46 and can slide freely therein, but the rotation of the lower shaft 30 causes the indexing wheel 44 to rotate around the neutral axis N .
- the electronic card 22 is provided with a validation sensor 24F which, like the directional sensors, is placed under an elastic dome 26F.
- a pressing on the wheel 12 causes a translation TP along the main axis P of the shaft 16, which slides in the orifice 46 of the indexing wheel 44, deforms the dome 26F and actuates the validation sensor 24F.
- the dome 26F resumes its original shape by exerting on the shaft a vertical restoring force F2 which pushes the shaft 16 to a high neutral position PN.
- the neutral position PN is then exactly defined by the alignment of the main axes P and neutral N and the wheel in the up position 26F dome is not deformed.
- the biasing means 42 in the neutral position PN of the wheel 12 thus comprises the domes, or other elastic means, opposing the pivoting, and the central dome 26F, opposing the main translation TP.
- the indexing wheel 44 may for example be arranged between uprights 48 forming vertical tongues defining a cylinder, the tongues 48 being provided at their upper end with lugs 50 horizontally being placed just above the indexing wheel 44 and thus keep it in position in the housing 14, while leaving it free to rotate around the neutral axis N.
- the cylindrical side surface of the wheel of indexing is provided with a rotation sensor 24E, optical or phonic wheel or any other technology, intended obviously, to detect and generate a signal function of the rotations of the indexing wheel 44 and therefore the rotations of the wheel 12.
- indexing wheel 44 is part of a discrete means
- the indexing wheel 44 is provided on its underside with a notched crown 54 whose notches 56 extend radially.
- An index 58 is vertically biased upwards by a spring 60 against the ring gear 54.
- a main rotation RP of the wheel 12 causes the indexing wheel 44 to rotate and forces the index 58, held in a housing of the case 14, to go from notch 56 to notch 56 amount then down successively the flanks of the notches 56.
- the rise of a blank is effected by compression of the spring 60 and therefore against it and the rotation in progress, while during the descent of a blank, the action of the spring 60 is driving and causes the rotation of the indexing wheel 44.
- the indexing means 52 thus determines a finite number of angular positions of immobilization of the wheel 12, each stable position PS corresponding to the positioning of the index 58 at the bottom of a notch 56. In the case where the index 58 would stand still, not at the bottom, the position of the wheel 12 would be unstable and the slightest external stress would result in an immediate adjustment of position so that the index is at the bottom of a notch. This adjustment can be detected by the angle sensor and cause a boring movement of a cursor on a control screen.
- the device 10 according to the invention is advantageously made of molded plastic parts and respects, during the main rotations RP of the wheel 12, a maximum torque of less than 5 N.cm. To do this, the surface conditions of the friction parts are carefully treated and the materials used chosen so as to minimize friction. With the index 58 going from notch 56 to notch 56, the rotation of the wheel 12 is pleasantly accompanied by a slight "click-click" and a cyclic force felt at the wheel 12. In the absence of parasitic friction, the rotation of the wheel 12 then always stops in one of the stable positions PS when the index 58 reaches the bottom of a notch 56.
- the indexing wheel 44 can be fixed in the housing 14 and the index 58 movable and secured to the shaft 16.
- the rotation sensor 24E can be arranged differently than on the wheel indexing 44 for example directly on the lower shaft 30.
