Definitions
- the present invention relates to a method of manufacturing a control device for a motor vehicle intended to control several functions of said vehicle.
- the passenger compartment of a motor vehicle constitutes for users - the driver and any passengers - a place to live and interact with controls which make it possible to control vehicle functions; these functions are very diverse in nature and may concern in particular the opening and closing of the vehicle doors, the orientation of the side mirrors, as well as the opening and closing of the windows fitted to the side doors of the vehicle.
- the commands which are typically found inside a vehicle and which constitute the interface for controlling the functions of a vehicle are in particular of the type: push buttons for, for example, controlling the locking of a vehicle, rotary knobs to, for example, control the temperature setting of the air conditioning system; rocker buttons, for example, to control the window opening/closing mechanism trigger, for example, to control the door opening mechanism sliders, for example, to control the temperature setting of the air conditioning system
- Such control devices are located in several places within the passenger compartment, for example on the door trim, in the armrest, near the gear lever, or even on the steering wheel.
- control devices buttons, sliders, etc. - are of the mechanical or electromechanical type.
- these control devices are, on the one hand, relatively expensive and, on the other hand, have significant installation constraints in the passenger compartment of the vehicle since they can only be positioned at locations which allow to accommodate their mechanisms. This last constraint therefore greatly reduces the freedom of design of the passenger compartment since the location of these members is dictated not according to ergonomic considerations but according to mechanical constraints which may be in contradiction with ergonomic considerations.
- a control device with electrical controls.
- the device then comprises a panel provided with inoperative zones, and with control zones.
- the control device comprises a sheet sensitive to touch via a detection surface coated with sensors.
- the sheet is arranged under the panel in such a way that each of the sensors are contiguous, that is to say, facing one of the control zones.
- Each sensor is configured to detect the presence of a user's finger, by sending a signal to an electronic control unit arranged on a printed circuit board.
- the contiguity between the sensors and the control zones is essential to allow the achievement of a good detection of the finger of the user, and thus to guarantee a good reactivity of the chosen function.
- control zones are arranged on a flat sector or a sector in relief.
- sector in relief reference is made to any zone having a clumsy shape, for example an embossment or a cavity.
- the sheet is thermoformed on an internal surface of the panel, in order to allow the shapes of the panel to be matched.
- One such method of assembling the sheet on the panel consists in heating the sheet to a predetermined temperature, before applying it by pressure to an internal surface of the panel.
- thermoforming process allows the adjustment of the sheet to the shape of the panel.
- contiguity in other words a shift between the control zones with sectors in relief, and the sensors.
- Such an anomaly comes from an excessive stretching of the sheet during its application on the internal surface. Stretching generates a deformation which remains during the hardening of the sheet after cooling.
- control device is energetically expensive, in particular due to the use of a heat source to allow the thermoforming to be carried out.
- the invention aims in particular to solve the aforementioned drawbacks.
- a first objective is to propose a process for manufacturing a panel which makes it possible to dispense with recalibration of the sensor, while offering the most optimal detection precision possible.
- a second objective is to propose such a method which makes it possible to produce a control device having raised sectors of very complex shape.
- a third objective is to propose such a process, which offers limited energy consumption.
- a fourth objective is to propose such a process, which requires a minimum number of steps.
- a fifth objective is to provide a panel obtained by the method presented above.
- a sixth objective is to provide a motor vehicle comprising such a panel.
- a method for manufacturing a detection assembly for a control device intended to be integrated into the passenger compartment of a motor vehicle including a panel comprising at least one sector in relief provided with an edge, a sheet comprising a detection surface provided with at least one sensor, the method comprising a step of forming at least one flap in the detection surface, a positioning step, the sheet being positioned facing the panel, the detection surface being positioned facing the sector in relief, a securing step, the sheet being applied against the panel, the flap being moved during the securing step to come into contact with a edge of the raised sector.
- shutters which are applied on sectors in relief makes it possible to avoid a deformation of the sensors during the application of the sheet, and to be freed from thermoforming when joining the sheet to the panel.
- the forming step comprises making cutouts or pre-cutouts within the detection surface, according to a predetermined pattern, so as to define a flap.
- the cutouts or pre-cutouts are made using a punch tool or a laser.
- the method comprises between the forming step and the positioning step, or before the forming step, a gluing step comprising the application of glue to the sheet.
- the sheet is provided with an inactive surface devoid of a sensor
- the gluing step comprises the application of a first glue on the inactive surface, and a second glue on the detection surface, after hardening of the first glue and the second glue, the second glue providing greater rigidity than the first glue.
- the securing step is carried out by a die-stamping machine, the die-stamping machine comprising a die able to translate, the die-stamping machine comprising a mobile part and a fixed part, the mobile part being able to translate relative to the fixed part so as to move between a retracted position and a contact position, the sheet being placed on the die in such a way that the moving part is facing the detection surface, the die-stamping machine performing a first movement aiming to put the sheet against the panel via the fixed part, and during a second movement, the movable part is moved from a retracted position to a contact position so as to apply the surface of detection against the raised sector.
- a detection assembly including: a panel comprising at least one sector in relief provided with an edge, as well as a sheet comprising a detection surface provided with at least one sensor, the sheet being secured opposite the panel, the detection surface being positioned opposite the sector in relief, the detection assembly comprising a flap secured to an edge of the sector in relief.

- a gluing step 101 the detection surface 21 and the inactive surface 22 of the sheet 7 are coated with a glue or an adhesive, so as to allow the assembly of the sheet 7 on the internal surface 9 of the panel 6.
- glue makes it possible to assemble the sheet 7 by gluing, making it possible to dispense with the thermoforming of said sheet 7 which consumes energy.
- putting on the sheet 7 of glue limits the risk of deformation of sheet 7, in contrast to a thermoforming operation which weakens the sensors 20 during the deformation of sheet 7.
- the inoperative zone 10 is coated with a first glue
- the control zone 2 is coated with a second glue.
- the first glue and the second glue are chosen so that after hardening, the second glue offers greater rigidity than that of the first glue. In this way, after assembly of the sheet 7 on the internal surface 9, the detection surfaces 21 and the inoperative zones 3 have a different rigidity.
- Such an arrangement prevents a deformation of a control zone 2 following the application of an effort by the user from being transmitted to an inactive surface 22, or to another detection surface 21.
- an effort caused by the pressure of a finger of the user on an edge 15 will only activate the detection of the sensor 20 associated with the edge 15, and not another sensor 20.
- the detection precision is thus ensured.
- the occurrence of undesirable deformation of any sensor 20 unrelated to the function chosen by the user is therefore considerably limited, avoiding any recalibration after assembly of the panel 2.
- a protective film is placed on the surfaces 21, 22 of the sheet 5, which makes it possible to protect the glue from any dirt or impurity.
- the sheet 7 can be handled, moved and stored without difficulty.
- cutouts 31 are made within the detection surface 21, according to a predetermined pattern, so as to form the flap 24.
- the pattern is determined according to the sector 12 in relief and the shape edges 15.
- the cutouts 31 are made with a punch tool or a laser, which allows rapid and economical formation of the flaps 24.
- the protective film is removed from the glued surfaces, before any joining between the panel 6 and the sheet 7.
- the gluing step 101 is carried out after the forming step 102, which makes it possible to dispense with the use of a protective film.
- a positioning step 103 the sheet 7 is placed facing the panel 6, for example facing the internal surface 9. In such a situation, the detection surface 21 is positioned opposite the sector 12 in relief.
- a securing step 104 the sheet 7 is brought close to the panel 6 until the sheet 7 is secured to the inner surface 9, for example being kept applied until the bonding between the surfaces 21, 22 previously glued , and the inner surface 9 takes place.
- a flap 24 is moved to come into contact with an edge 15 of the sector 11 in relief facing it.
- the positioning step 103 and the joining step 104 are advantageously carried out on a stamping machine 32 as shown in Figures 9 to 11.
- Such a stamping machine 32 comprises a die 33, which translates for example in a vertical direction.
- the matrix 33 is advantageously provided with fixed parts 34, and with movable parts 35.
- the matrix 33 moves in translation, between a distal position shown in Figure 9, and a proximal position shown in Figures 10 and 11.
- the movable parts 35 are movable in translation within the matrix 33, moving between a retracted position visible in the 9, 10, and a contact position visible in figure 11.
- the matrix 33 advantageously has a contact surface 36 which defines a shape complementary to the shape of the internal surface 9.
- the contact surface 36 reproduces in negative, that is to say in an inverted manner, the sectors 12 in relief.
- the joining step 104 is carried out as follows.
- the sheet 7 is deposited on the matrix 33, the detection surfaces 21 provided with cutouts 31 being positioned facing the moving parts 35 .
- the moving parts 35 are in the retracted position. Such a situation is shown in Figure 9.
- the matrix 33 is brought close to the internal surface 9 so as to reach a proximal position, allowing the fixed parts 34 to be applied against the sheet 7. In this way the inoperative zones 10 can be glued.
- the moving parts 35 preferably remain retracted, and do not interfere with the sheet 7. Such a situation is shown in Figure 10.
- the first movement precedes the second movement, which allows assembly by gluing of the inoperative zones 10, before the gluing of the flaps 24 against the edge 15.
- this promotes the formation of folds 23, hinges 26, folds 27 and thus considerably reduces the risk of offset between the facets 25 and the edges 15.
- the occurrence of the phenomenon of deformation of the sensors 20, is considerably limited, which avoids any recalibration after assembly of the panel 6.
- the first movement and the second movement are carried out simultaneously, which saves time during the manufacture of the detection assembly 3.
- the movable parts 35 have a complementary shape with the sectors 12 in relief, which facilitates the placement of the facets 25 on the edges 15.
- the moving parts 35 have the shape of a finger. Such moving parts 35 offer less precision, but make it possible to avoid a change of tool in the event of a change in the shape of the sectors 12 in relief.
- the stamping machine 32 comprises both moving parts 35 having the shape of a finger, and other moving parts 35 having complementary shapes with the sectors 12 in relief.
- the moving part 35 is not limited to the performance of a single movement, but performs a plurality of movements so as to apply each of the facets 25 to a respective edge 15.
- the detection assembly 3 thus manufactured, an intermediate element 4, then an electronic card are advantageously assembled to the detection assembly 3, by means known to those skilled in the art, during an assembly step 105, represented in FIG. 12.
- Such an assembly step 105 enables the formation of the control device 1 .
- the manufacturing method of the control device 1 offers many advantages such as: the production of a control device 1 having sensors 20 that do not require recalibration after the shaping of the control device 1, the possibility of positioning flaps 24 in sectors 12 in relief having complex shapes, reduced energy use compared to a process using thermoforming, possible implementation on pre-existing machines such as a stamping machine, manufacturing time reduced.
