- the vehicle 10 corresponds for example to a vehicle with a combustion engine, with electric motor(s) or else a hybrid vehicle with a combustion engine and one or more electric motors.
- the vehicle 1 thus corresponds for example to a land vehicle, for example an automobile, a truck, a coach.
- a mobile communication device 101 is advantageously arranged on the dashboard and maintained on the latter via a support system 100 for a mobile communication device.
- the mobile communication device 101 corresponds for example to a smart phone or a tablet.
- the mobile communication device 101 is connected to the vehicle 10 via a wireless connection, for example a Bluetooth® or Wifi® connection, for example Wifi Direct (according to IEEE 802.11, for example according to IEEE 802.11h or IEEE 802.11ac).
- a wireless connection for example a Bluetooth® or Wifi® connection, for example Wifi Direct (according to IEEE 802.11, for example according to IEEE 802.11h or IEEE 802.11ac).
- the mobile communication device 101 is connected to the vehicle 10 via a USB cable (from the English “Universal Serial Bus” or “Universal Serial Bus” in French), for example to recharge the battery of the mobile communication device 101.
- a USB cable from the English “Universal Serial Bus” or “Universal Serial Bus” in French
- the support system 100 is adapted to hold the mobile communication device 101 to allow a user installed in the passenger compartment of the vehicle 10 to see the screen of the device 101.
- the support system 100 is thus configured to hold the device 101 in a vertical or essentially vertical position, the screen of the device 101 facing one or more passengers of the vehicle 10.

- the support system 100 is fixed to the windshield of the vehicle 10 or to any other element of the passenger compartment of the vehicle 10.
- FIG. 2 schematically illustrates the support system 100 configured to hold a mobile communication device in position in the passenger compartment of a vehicle, according to a particular and non-limiting embodiment of the present invention.
- the support system 100 is advantageously obtained or produced by additive manufacturing by melting on a powder bed.
- the support system 100 is for example manufactured according to a method implementing selective laser sintering, known as the SLS (Selective Laser Sintering) method.
- SLS Selective Laser Sintering
- Such a manufacturing process makes it possible to produce 3D (three-dimensional) objects by depositing layers of powder on top of each other and one after the other as the process progresses, each layer being subjected to laser radiation which makes it possible to sinter or fuse the powder according to a 3D model thanks to the energy of the laser (comprising for example between 200 and 400 W), such as a CO2 laser for example. All the parts forming the support system are printed in one go, i.e.
- the parts are printed in such a way that no assembly of the parts is required between them after printing to obtain the support system 100.
- Selective laser sintering has the advantage of allowing the printing of systems or parts with complex geometries via the implementation, for example, of 3D modeling techniques such as topological optimization.

- MJF method from the English Multi Jet Fusion "
- the powder is brought to its melting point in the MJF method, maintaining the principle of depositing successive layers of powder to print the system as a whole at once, and not piece by piece.
- the melting of the powder is obtained by using a binder subjected to infrared radiation.
- a liquid binder is for example sprayed (for example in the form of 80 ⁇ m droplets) onto a bed of powder, which solidifies layer after layer to form the final system at the end of the process.
- the MJF method and more particularly the MJF HP method, allows a significant gain in productivity compared to the SLS method.
- the support system 100 is for example made of nylon type PA11 (Polyamide 11) or PA12 (Polyamide 12).
- PA11 has the advantage of being of renewable origin (derived from castor oil) and of offering superior mechanical properties to PA12, in particular superior impact and abrasion resistance.
- the support system 100 is made from a metal powder, for example an aluminum-based alloy.
- the support system 100 is formed of a set of parts cooperating with each other and comprising in particular a body 20, a member 22 movable vis-à-vis the body 20 and a wheel 21 for driving the member 22 in translation when a rotational movement is applied to the wheel 21.
- the body 20 advantageously comprises a housing 201 configured to receive the mobile communication device 101.
- the housing 201 corresponds for example to a space hollowed out in the body 20, for example in the general shape of a U, with one face forming the bottom of the hollow space on which applies the back of the mobile communication device 101, this face having a determined height (for example equal to a few centimeters) corresponding to the height of the support system 100 for example.
- the housing 201 is closed on its sides by two side walls, a first fixed side wall 202 formed by the body 20 and a second movable side wall formed by one end of the movable member 22.
- the first side wall 202 and the second wall advantageously form a vice for clamping the mobile communication device, a first side portion of the mobile communication device 101 bearing against the first side wall 202 and a second side portion (opposite to the first side portion) of the mobile communication device 101 bearing against the second side wall.
- a support system 100 thus makes it possible to hold the mobile communication device in position in a stable manner.
- the member 22 being mobile, the space between the first side wall 202 and the second side wall is adjustable (by rotation of the wheel 21), which makes it possible to adjust the clamping force on the mobile communication device 101 and to receive mobile communication devices of different sizes, in particular of different widths.
- the face forming the bottom of the housing 201 is customizable, for example by printing a text, a graphic object such as an icon or a logo, during the manufacturing process of the support system by 3D printing, called also additive manufacturing.
- FIG. 3 schematically illustrates a view in longitudinal section of a part of the support system 100, according to a particular and non-limiting embodiment of the present invention.
- FIG. 3 illustrates a part of the support system 100 according to a longitudinal section, in the plane formed by the X and Y axes of an orthonormal frame in which the longitudinal axis of the support system 100 is according to the X axis.
- the movable member 22 advantageously comprises a part forming a nut 32, a part forming a clamping element 34 of the mobile communication device and a part 33 connecting the nut 22 to the clamping element 34.
- a first thread 321 is formed in the nut part 32.
- the body 20 advantageously comprises a hollow part 301 forming a chamber to receive at least partly the movable member 22, in particular the part 32 of the movable member 22 forming a nut.
- the dimensions of the hollow part 301 are adapted to allow a translation of the movable member 22 along the axis X, allowing a stroke for example equal to 1, 2, 3, 4 or 5 cm of the part forming a nut 32 in the hollow part 301 along the axis X.
- the body also comprises at one of its longitudinal ends a tubular end portion 30, this tubular end portion comprising a thread, called second thread, on its inner contour.
- the tubular end portion 30 thus forms a nut.
- the shape of the nut 32 and the shape of the hollow part 301 are provided so that the nut 32 is mounted or housed in sliding connection with the body 20 of the support system 100.
- the cross section of the hollow part 301 is for example rectangular and the cross section of the nut 32 is also rectangular, the dimensions of the section of the nut 32 being smaller than those of the section of the hollow part 301 to allow a translation of the nut 32 in the hollow part 301.
- the sections of the hollow part 301 and of the nut 32 are circular, the external envelope of the nut 32 being for example grooved to cooperate with one or more tabs formed on the inner contour of the hollow part to allow the slide connection.
- the wheel 21 advantageously comprises a head from which extends a screw 31.
- the screw 31 advantageously comprises two threads, a first thread 311 formed on an end portion of the screw and a second thread 312 formed on a portion of the screw in contact with the head of the wheel 21.
- the screw 31 corresponds for example to a differential screw, the screw pitch of the first thread 311 being different from the screw pitch of the second thread 312.
- the screw pitch of the first thread 311 is by example greater than the screw pitch of the second thread 312.
- the end portion of the screw 31 receiving the first thread 311 has for example a diameter smaller than the portion of the screw 32 receiving the second thread 312. In other words, the outer diameter (called first outer diameter) of the first thread 311 is smaller than the outer diameter (called second outer diameter) of the second thread 312.
- the first thread 311 is adapted to cooperate with the first internal thread 321 and the second thread 312 is adapted to cooperate with the second internal thread 302.
- the head of wheel 21 is circular or essentially circular in shape.
- the head of the wheel is hollow and comprises a bottom 310 from which the screw 31 extends.
- a circular cavity 313 is advantageously formed in the head between an interior contour of the hollow head and an exterior contour of the screw 31 (in particular of the portion of the screw 31 attached to the bottom 310 and receiving the second thread 312), the circular cavity being provided to allow the engagement of the knob 21 on the tubular end portion 30 of the body 20.
- Such an engagement is obtained by printing a rotational movement of the wheel 21 in a screwing direction, the second thread 312 engaging with the second thread 302 of the part forming the nut of the tubular end portion 30.
- a shoulder or bead of material 303 is advantageously formed on the outer contour of the tubular portion 30, at the end of this tubular portion 30, to limit the travel of wheel 21 along the X axis and prevent withdrawal of wheel 21 from support system 20.
- a return of the head of wheel 21 comes into abutment against shoulder 303 when a translational movement is printed on the wheel 21 along the X axis to prevent any withdrawal of the wheel 21 .
- the parts forming the support system 20 are arranged in two different arrangements.
- the parts are in a first arrangement when the support system 20 is in a so-called support system printing state or position.
- a printing position corresponds to the position of the system 20 and the parts that compose it at the end of the manufacture of the system 20 by 3D printing.
- Figure 3 illustrates such a first arrangement.
- the parts are according to a second arrangement when the support system 20 is in a state or a position called use of the support system 20.
- a printing position corresponds to the position of the system 20 and the parts that compose it when the support system is used to hold the mobile communication device 101.
- the second thread 312 is not engaged with the second thread 302, i.e. no thread of the second thread 312 is introduced into the second thread 302. end of the second thread is thus at a determined distance from the end thread of the second internal thread 302. Conversely, in the first arrangement, the first thread 311 is engaged with the second internal thread 321 over a first determined thread length, for example on one or two threads of the first thread 311 .
- the first screw-nut system formed by the first thread 311 and the first internal thread 321 makes it possible to drive the movable member 22 in translation when a rotational movement is applied to the wheel 21 .
- the first thread 311 being engaged with the first internal thread 321 during the manufacturing or printing phase of the support system 100, it is necessary to provide sufficient play between on the one hand the thread or threads of the first thread 311 in taken in the first thread 321 and on the other hand the thread or threads of the first thread 321 in which the thread or threads of the first 311 threads are engaged.
- Such a clearance, greater than a first threshold is necessary to prevent the particles of powder forming the first thread 311 from merging with the particles of powder forming the first thread 321 during the 3D printing phase of the support system 100.
- the problem associated with such a first game is that a flutter between the wheel 21 and the movable member 22 is felt by a user screwing the wheel 21 to tighten the mobile communication device 101, giving an impression of low quality of the system of communication. support 100. Furthermore, the precision of the adjustment of the tightening via the rotation of the knob 21 is also reduced because of such a first clearance.
- the diameter of the first thread or threads at the end of the first thread 311 (that is to say the threads engaged in the first thread 321 during the 3D printing phase) have a diameter exterior to that of the other threads of the first thread 311.
- Such a feature makes it possible to increase the distance or the clearance between the outer contour of this or these first threads and the threads of the first internal thread 321, which reduces the risk of fusion between this or these first threads and the thread or threads of the first tapping 321 in which they are introduced.
- a second screw-nut system is provided.
- This second screw-nut system is formed by the second thread 312 and the second thread 302.
- the second thread 312 is recessed with respect to the second thread 302 and n is not in touch with the latter.
- This characteristic makes it possible to provide a second clearance, less than the first clearance, between the second thread 312 and the second internal thread 302.
- the second clearance corresponds for example to a tight clearance and makes it possible to compensate for the "floating" felt because of the first clearance.
- the association of the first thread and the second thread makes it possible to form a differential screw 31, which makes it possible to refine the adjustment of the tightening of the mobile communication device 101 when the knob 21 is turned in the direction of tightening.
- the second thread 312 meshes with the second thread 302 and the number of threads of the first thread 311 meshes with the first thread 321 is greater than the number of threads of the first thread 311 engaged with the first thread 321 in the first arrangement (during the manufacturing or 3D printing phase of the system 100).
- the first thread 311 engages with the first internal thread 321 over a thread length greater than the length along which the first thread 311 engages with the first internal thread 321 in the first arrangement.
- the head of the wheel 21 is thus better fitted into the tubular end portion 30 of the body 20.
- the rotation of the wheel 21 in the direction of tightening drives in translation the movable member 22 which comes to tighten in vice the mobile communication device 101 placed in the housing 201.
- the rotation of the knob 21 in the opposite direction drives in translation in an opposite direction the movable member 22 which comes to loosen the vice formed on the device mobile communication 101, allowing the removal of the device 101 from the support system 100.
- FIG. 4 illustrates a flowchart of the different steps of a method of manufacturing a support system such as the support system 100 described with reference to Figures 1 to 3, according to a particular and non-limiting embodiment of the present invention.
- the method is for example implemented by a 3D printer.
- the method advantageously implements a method called additive manufacturing by melting on a powder bed, for example a method called SLS, MJF or MJF HP.
- a first step 41 data representative of a three-dimensional (3D) model of the support system 100 is received.
- This data is, for example, received from a computer connected to the 3D printer via a wired link (for example of the Ethernet or USB type) or via a wireless link (for example of the Wifi® type).
- these data are received from a data storage device, of the USB key type introduced into an interface of the 3D printer provided for this purpose.
- a powder bed is deposited on a support plate by an element of the 3D printer provided for this purpose.
- the powder corresponds for example to PA11.
- the powder bed deposited in the second step is scanned by a laser, the scanning being controlled by a control unit of the 3D printer according to instructions obtained from the data received.
- a liquid binder is deposited on the powder bed by one or more nozzles of a print head of the 3D printer before scanning or as scanning progresses.
- the support plate is lowered by a determined height, for example a height of between 20 and 60 ⁇ m.
- a determined height for example a height of between 20 and 60 ⁇ m.
- Such a height corresponds to the height of each layer or stratum making it possible to obtain the support system 100.
- a new powder bed (that is to say a new layer of powder) is deposited on the layer previously obtained in step 43.
- the method continues by reiterating steps 43, 44 and 45, ending with a scanning step 43 when the last layer making it possible to obtain the support system 100 by 3D printing has been deposited.
- the parts forming the support system 100 are arranged according to the first arrangement described with reference to FIG.
- the method further comprises one or more finishing steps by treatment of the surface of the outer envelope of the support system 100.
- the method further comprises a step of painting the surface of the outer casing of the support system by applying one or more coats of paint.
