    Modular drone
    The invention relates to a modular drone.
    In the sense of the present invention, a drone is a mobile motorized device without pilot, which can be controlled remotely to move in the air or on the ground.
    A drone conventionally comprises a base and several arms each supporting a motor, the various motors making it possible to move the drone. When it is an aerial drone, the motors drive propellers, the rotation of which allows the drone to lift. When it is a land drone, the motors drive wheels or tracks.
    The base of a drone is an elaborate and therefore expensive equipment, which includes, among other things, means of power supply and control of the different motors, as well as means of remote communication with a remote control and, possibly, a parachute. of security. Such a base is also generally designed to support one or more accessories, such as a camera or a camera.
    The conditions of use of a drone are variable, depending on the autonomy sought, the carrying capacity to be provided and the regulations in force.
    Under these conditions, it is known to produce a drone in the form of a base and a set of arms removably mounted on a body of this base, the set of arms being suitable for the use intended for the drone. . It is thus possible for the user or the operator of a drone to have a base and several sets of arms, each set of arms being intended for a type of use.
    In addition, a removable mounting of the drone's arms on its base makes it possible to store the arms apart from the base when transporting the drone.
    It is necessary to circulate, between the base and the different arms, a current necessary for the operation of the different motors, as well as, if necessary, electrical signals for controlling these motors. On the other hand, the attachment of each arm to the body of the base must be reliable, while being easy and quick to implement by a user, at the site of use of the drone, that is to say - say most often outdoors. In particular, the positioning of the different arms on the body of the drone base must be able to be carried out quickly, without the risk of bad attachment or risk of deterioration or premature wear of electrical contacts between the base and each arms.
    It is to these constraints that the present invention intends to respond more particularly, by proposing a new modular drone in which the mounting of the arms on the base is both reliable and rapid, while avoiding premature wear of the electrical contacts between the base and arms of this drone.
    To this end, the invention relates to a modular drone which comprises a base, with a body including at least one current source for a motor for moving this drone, as well as a set of arms intended to be removably mounted on the body of the base, each arm supporting at least one drone displacement motor. According to the invention, this drone comprises a first interface formed either on an arm, at its mounting end on the base, or, on the body of the base, at a mounting area d 'an arm. This first interface includes a first base surface and a central nose which extends, with respect to the first base surface, along a first longitudinal axis and which is equipped with first electrical contact members. This first interface also includes at least one member equipped with at least one tapping or threading section. The drone also comprises a second interface formed on the body of the base, at the level of the arm mounting zone on the base, when the first interface is formed on the arm, or on the arm, at its end. mounting on the body of the base, when the first interface is formed on the body of the base. This second interface includes a second base surface which receives the first base surface when the arm is mounted on the body of the base, as well as a cavity for receiving the central nose, this cavity extending relative to to the second base surface, along a second longitudinal axis superimposed on the first longitudinal axis when the arm is mounted on the body of the base, this cavity being equipped with second electrical contact members complementary to the first electrical contact members. This second interface also includes a locking ring arranged around the cavity and rotatably mounted around the second longitudinal axis, this locking ring being equipped with at least one peripheral relief, in the form of a section of thread or complementary tapping. (s) of the tapping or threading section of the member of the first interface.
    Thanks to the invention, the mounting of an arm of the drone on the body of the base is carried out by introducing the nose of the first interface into the cavity of the second interface, which makes it possible to center the first interfaces one relative to the other, then by turning the locking ring to bring its peripheral relief (s) into engagement with the tapping or threading section (s) of the member of the first interface, which allows to take up an axial clearance between the first and second interfaces and to mechanically secure the assembly, while guaranteeing electrical continuity between the first and second electrical contact members. The disassembly of the arm takes place by reversing the above sequence. This assembly and disassembly are both quick and easy to implement, while ensuring long-term attachment of the arm to the base of the drone.
    According to advantageous but not compulsory aspects of the invention, such a drone can incorporate one or more of the following characteristics, taken in any technically admissible combination:
    - The member of the first interface is formed by at least one stud which extends, relative to the first base surface, on the same side as the central nose and which is equipped with a tapping section, while the relief device of the locking ring is in the form of a section (s) of complementary thread (s) of the tapping section of the stud of the first interface.
    - As a variant, the member of the first interface is formed by the nose which is equipped with at least one threading section, while the peripheral relief of the locking ring is in the form of a section (s) of complementary tapping (s ) of the threading section of this nose.
    - The amplitude of rotation of the locking ring around the second longitudinal axis is limited and less than 60 °, preferably less than 45 °, more preferably between 30 and 35 °.
    - The drone comprises at least one seal ensuring the tightness of the mounting of the nose of the first interface in the cavity of the second interface and / or at least one seal ensuring the tightness of the mounting of the second interface on the body of the base or arm.
    - The locking ring is immobilized axially, along the second longitudinal axis, between a part defining the cavity and a body on which this part is attached.
    - The locking ring is equipped with rotation blocking members, around the second longitudinal axis, in one of two predetermined angular positions relative to a part defining the cavity, the ring allowing the introduction of the nose into the cavity and its withdrawal when it is in a first angular position, among these two predetermined angular positions, and the ring preventing the introduction of the nose into the cavity and its withdrawal when it is in the second angular position, among these two angular positions predetermined.
    - The locking members comprise a button mounted on the locking ring, movable relative to the latter in a radial direction to the second longitudinal axis and equipped with a pin projecting towards the part defining the cavity. The part defining the cavity is equipped, on one side facing the locking ring, with a pin guide groove which extends between two seats for receiving this pin. The button is subjected to the action of an elastic return member from the pin towards the bottom of the seats of the part defining the cavity.
    - The button is fitted with an identification mark because the pin is at the bottom of one of the two seats.
    - The second interface includes two identification marks of the two predetermined positions, preferably in the form of pictograms respectively arranged near the button when it is in each of these positions.
    - The first electrical contact members are arranged on an end face of the nose, while the second electrical contact members are arranged at the bottom of the cavity and that, preferably, at least some of these electrical contact members are piston contacts.
    - The arm includes a one-piece body fitted with a pressure-balancing opening between its interior volume and the ambient atmosphere, this opening being closed by a water-tight and gas-porous plug.
    The invention will be better understood and other advantages of it will appear more clearly in the light of the following description of an embodiment of a drone in accordance with its principle, given solely by way of example and made with reference to the accompanying drawings, in which:
    - Figure 1 is a schematic perspective representation of a drone according to the invention;
    - Figure 2 is a partial perspective view of the junction between an arm and the base of the drone of Figure 1;
    - Figure 3 is an enlarged view of detail III in Figure 2;
    - Figure 4 is an enlarged view of detail IV in Figure 2;
    FIG. 5 is a view similar to FIG. 2, taken from another angle,
    FIG. 6 is an enlarged view of detail VI in FIG. 3 and
    - Figure 7 is a section oriented upwards along plane VII in Figure 1.
    The drone 2 according to the invention shown in Figures 1 to 4 comprises a base 4, on which are removably mounted, four arms 6A, 6B, 6C and 6D.
    These arms are identical. For clarity of the drawing, the arms 6B, 6C and 6D are only shown partially.
    As visible only for the arm 6A, each of the arms comprises an electric motor 8 for driving a two-bladed propeller 10. As a variant, the propeller 10 can be three or four-bladed. According to another variant, two motors can be provided one above the other on the arms 6A to 6D, each motor driving a propeller.
    Each of the motors 8 is electrically supplied from a battery 12 integrated in a body 14 of the base 4. Electric wires, not shown, run between the battery 12 and each of the motors 8, these wires being interrupted at the level of the mounting zones of the arms 6A to 6D on the body 14. The body 14 also contains an electronic unit 16 for controlling the motors 8, which is connected by conductive wires to each of these motors, these conductive wires also being interrupted at these mounting areas.
    The body 14 of the base 4 also includes an antenna 18 for communication with a remote control 20 intended to be taken in hand by a user and which comprises means for piloting the drone 2, in particular in the form of one or more joysticks and / or one or more buttons. In practice, the remote control 20 can be of any suitable type.
    Alternatively, the antenna 18 can be replaced by a wired connection with the remote control. In this case, the battery 20 can be supplemented by current supply means provided on the ground or replaced by the termination of a ground connection cable.
    The body 14 also supports a safety parachute 22 which can be triggered remotely in the event of damage, in order to slow the fall of the drone 2 under the effect of gravity.
    The arms 6A to 6D are mounted on the body 14 of the base 4 in a removable manner, which makes it possible to disassemble them when the body 2 must be transported.
    The removable nature of the assembly between the base 4 and the arms 6A to 6D also makes it possible to substitute for these arms another set of arms configured in a different manner to take account of the conditions of use of the drone 2, as represented by the arms 6Ά and 6 ”A in Figure 1, which also include at least one motor 8 and one propeller. In practice, the arms 6A to 6D are then all replaced by arms of the 6Ά or 6 ”A type.
    In a variant not shown, the arms mounted on the body 14 of the base 4 are provided with wheels or tracks allowing the drone 2 to move on the ground.
    In the following, and in Figures 2 and following, the reference 6 is used to identify one of the arms 6A to 6D, 6Ά, 6 ”A or equivalent.
    The removable nature of the mounting of an arm 6 on the body 14 of the base 4 is obtained by means of two interfaces 100 and 200 provided respectively at one end 62 of the arm 6 facing the base 4 in the mounted configuration of the arm, and at a zone 24 of the body 14 provided for mounting this arm.
    The arm 6 comprises an elongated body 64 made of a composite material, with carbon fibers, and which ends, on the side of the base 4, by the end 62. This material is impermeable to gases and liquids. V6 the interior volume of the arm 6, which is accessible through the end 62.
    The first interface 100 comprises a part 102 made of metal, for example aluminum, this part 102 being a single piece and comprising a plate 102A and a skirt 102B which extends from the plate 102A so as to cover the end 62 in mounted configuration of the arm 6 on the body 14. In practice, the skirt 102B can be force fitted, glued or riveted to the end 62.
    The surface 102C of the plate 102 opposite the skirt 102B is planar. X100 denotes an axis perpendicular to the surface 102C. A nose 102D in one piece with the rest of the piece 102 extends, from the surface 102C, opposite the skirt 102B. The X100 axis constitutes a longitudinal axis for the 102D nose which is hollow.
    On the outside, the nose 102D is provided with two peripheral grooves in which are arranged two seals 104.
    Two identical studs 106 are attached to the piece 102. These studs are arranged on either side of the nose 104 and are immobilized on the piece 102 by means of screws 108 which pass through the plate 102A and are screwed into the studs 106. The studs 106 extend, from the surface 102A, on the same side of the plate 102 as the nose 102D.
    The studs 106 are made of steel, so that they have good mechanical resistance. Furthermore, given their relatively small volume, they do not significantly increase the interface 100, which remains light given the relatively low density of the aluminum used for the part 102.
    Each of the studs 106 is provided, on its side facing the nose 102D, with a groove 106A in the form of a tapping section. In other words, each of the grooves 106A is in the form of a propeller section centered on the axis X100. The section of each of the grooves 106A can be chosen according to the type of tapping to be used, for example a tapping with a diameter of 30mm and a pitch of 0.7mm. The pitch can be changed to modify the desired clamping force.
    The interface 100 also includes a wafer 110 fitted with pads 112 which form the first electrical contact members. The plate 110 is immobilized on the nose 102D by means of two screws 114. Once in position on the nose 102D, the plate 110 forms an end face of the nose 102.
    The pellets 112 are connected to conductive wires (not shown) which extend inside the nose 102D, pass through the plate 102A and enter the volume V6 of the arm 6 to supply and drive the motor (s) 8 mounted ( s) on this arm.
    The interface 100 includes all of the parts 108 and 114.
    The second interface 200 comprises a part 202 also made of metal, preferably aluminum, and which is mounted on the zone 24 of the body 14 by means of four screws 204.
    The part 202 comprises a plate 202A from which extends a hollow boss 202B, opposite a generally planar surface 202C and perpendicular to an axis X200 of the interface 200. The internal volume of the boss 202B defines a 202D waterproof receiving cavity 102D of the nose 102D when the surfaces 102C and 202C are in contact with one another.
    To do this, the section of the cavity 202D perpendicular to the axis X200 is adapted to the outside section of the nose 102D perpendicular to the axis X200. The geometry of the cavity 202D is such that the seals 104 come to bear against the internal surface of the boss 202B when the nose 102D is introduced into this cavity, which isolates the end face of the nose 102D, therefore the pellets 112, from outside.
    On the outside, the boss 202B is equipped with a peripheral seal 206. When the plate 202 is mounted on the zone 24, the boss 202B penetrates into an opening 14D of the body 14 located in the zone 24 and whose section is adapted to that of the boss 202B, so that the seal 206 abuts against the surface of the body 14 which delimits the opening 14D. The seal 206 therefore constitutes a tight barrier, which protects the interior volume of the body 14 against impurities and humidity.
    Furthermore, a plate 210 is mounted on the part 202 by means of screws 214. This plate is equipped with second electrical contact members 212 complementary to the pads 112 and which, in the example, are piston contacts, which allows compensate for a possible lack of parallelism and / or an axial difference between the plates 112 and 212 when the nose 102D is in place in the cavity 202D.
    Wires not shown extend from the piston contacts 212 towards the battery 12 and the electronic control unit 16.
    The plate 210 constitutes the bottom of the cavity 202D.
    As the contacts 212 are arranged at the bottom of the cavity 202D when the plate 210 is in place on the part 202, these contacts are protected from shocks, including when the arm 6 is disassembled.
    When the nose 102D is in position in the cavity 202D, the axes X100 and X200 are merged.
    A locking ring 240 is mounted on the part 202, around the boss 202B and makes it possible to lock the plates 102 and 202 in a configuration where the nose 102D is in place in the cavity 202D.
    This locking ring 240 is made of steel and comprises, on its external peripheral surface 240A, two series of diametrically opposite grooves 240B, one of which is visible in the upper part of the locking ring 240, in FIGS. 2 and 4 to 6, and the other of which is located in the lower part of this ring.
    The locking ring 240 is movable in rotation, about the axis X200, relative to the plate 202. The grooves 240B allow a user to exert a driving torque of the ring 240 around the axis X200.
    On its external peripheral surface 240A, the locking ring 240 carries two reliefs 240C, each in the form of a thread section. The geometry of the external peripheral reliefs or sections of thread 240C is adapted to the geometry of the grooves or tapping sections 106A, so that the locking ring 240 can be screwed in and between the studs 106. The thread in which the 240C reliefs can also be 30mm in diameter and 0.7mm pitch. The pitch can be changed to modify the desired clamping force.
    The plate 202A is pierced with two openings 202E for the passage of the studs 106 when the surfaces 102C and 202C are brought opposite or in contact with one another, due to the introduction of the nose 102D into the cavity 202D, during mounting the arm 6 on the body 14.
    On the other hand, a surface 202G of the plate 202A opposite the surface 202C is oriented towards the locking ring 240. This surface 202G is provided with a groove 202H in the form of an arc of a circle centered on the axis X200, at the end of which two seats 202J and 202L are provided.
    For its part, the locking ring 240 is equipped with a button 250 which is pushed back by a spring 252 radially towards the outside of the peripheral surface 240A. This button 250 carries a pin 254 which passes through a bore 250A provided in the button 250, to the point that this pin 254 protrudes from the button 250A in the direction of the surface 202G when the ring 240 is mounted around the boss 202B. In this configuration, the pin 254 penetrates into the groove 202H, so that this groove 202H defines, by its angle at the apex a, the angular amplitude of the rotation of the ring 240 around the boss 202B.
    The angle a, therefore the angular amplitude of rotation of the locking ring 240, is chosen less than 60 °, preferably less than 45 °, more preferably between 30 and 35 °.
    Furthermore, due to the action of the spring 252, when the pin 254 arrives at one of the ends of the groove 252H, this pin is automatically pushed towards the bottom of one of the seats 202J or 202L. Thus, the locking ring 240 is automatically locked in rotation around the X200 axis when it reaches one or the other of the ends of its rotational travel around the X200 axis.
    In the mounted configuration, most of the pin 250 and the spring 252 are arranged inside an internal cavity 240D of the locking ring 240.
    The button 250 is equipped with a color mark 250B which extends around this button, near its external radial surface 250C. When the ring 240 is in one of its predetermined positions corresponding to the engagement of the pin 254 in one of the seats 202J or 202L, the button 250 projects radially outside the peripheral surface 240A of the ring 240 under the action of the spring 252 to the point that the colored mark 250B is visible. On the contrary, when the pin 250A is in an intermediate position between the seats 202J and 202L, along the groove 202H, the pin 250 is brought back radially in the direction of the axis X200 in the cavity 240D, against the action of the spring 252, to the point that the colored mark 250B is not visible. Thus, it is possible for the user to identify that the locking ring 240 is in one of its two predetermined positions, at the ends of its travel, when the colored mark 250B is visible on the outside of the surface 240A.
    The interface 200 includes all of the parts 202 to 254.
    On the other hand, the zone 24 of the body 14 forms a skirt 24A which surrounds the part 202, the plate 210 and the ring 240B when the part 202 is immobilized on the body 14 by means of the screws 204. In this configuration, the ring 240 is retained axially, along the axis X200, between the plate 202A and the body 14, which makes this ring captive.
    The skirt 24A is interrupted locally at two notches 24B and 24C, which allows the ring 240 to protrude radially from the body 24, relative to the axis X200, giving access to the user to the grooves 240B which are provided on two diametrically opposite zones of the ring 240. The button 250, which slightly protrudes from the grooves 240B, and a cube-shaped relief, provided in the center of the grooves formed at the bottom in the locking ring 240, are also accessible through the notches 24B and 24C. It is thus possible for the user to exert a torque on the ring 240 making it possible to pass the latter from a first angular position, where its pin 254 is engaged in the seat 202J, to a second angular position, where this pin 254 is engaged in seat 202L, and vice versa.
    The reliefs or thread sections 240C are arranged on the ring 240 so that, when its pin 254A is in place in the seat 202J, the reliefs 240C are angularly offset, around the axes X100 and X200 then combined, relative to the studs 106. It is then possible to introduce the nose 102D into the cavity 202D, without discomfort linked to the ring 240. As a result of this introduction, the studs 206 penetrate into the openings 202E so that the surfaces 102C and 202C come to bear one against the other and that the grooves or thread sections 106A come in axial alignment, along the axes X100 and X200 combined, with the reliefs or thread sections 240C. By rotating the locking ring 240 in the direction of the arrow F1 in FIG. 4, it is then possible to penetrate the reliefs 240C in the grooves 106A, which has the effect of screwing the locking ring 240 in and between the studs 106, on the angular travel defined by the angle a.
    To carry out this screwing, the user should press the button 250 in order to eject the pin 250A from the seat 202J to bring it into the groove 202H. The rotation of the ring 240 and the screwing of this ring in the studs 106 continue until the pin 254 reaches opposite the seat 202L where it is automatically engaged under the action of the spring 252.
    The angle a is chosen so that, in this angular position of the locking ring 240 with engagement of the pin 254 in the seat 202L, the thread sections 240 are engaged in the grooves 106A, without coming out.
    The fact of screwing the locking ring 240 in the studs 106 has the effect of exerting between the parts 102 and 202 an axial approximation force which is added to the effect of the initial fitting of the nose 102D into the cavity 202D . This reinforces the support of the surfaces 102C and 202C and the electrical contact members 112 and 212 against each other.
    At the end of the screwing of the ring 240, the arm 6 is firmly immobilized on the body 14, with good electrical conductivity at the level of the members 112 and 212 and without risk of separation or vibration of the arm 6 relative to the base 4 .
    When it is necessary to dismantle the arm 6 relative to the body 14, it suffices for the user to exert on the button 250 a centripetal force in the direction of the axis X200 to release the pin 254 from the seat 202L, then turn the ring 240 in the direction of the arrow F2 in FIG. 3, so as to bring the pin 254 into the seat 202J. In this predetermined angular position, the reliefs 240C have come out of the grooves 106A, so that the ring 240 does not oppose the extraction of the nose 102D outside the cavity 202D.
    It is understood that the two predetermined angular positions defined respectively by the seats 202J and 202L respectively correspond to an unlocked configuration and to a locked configuration of the interface 200, which can be identified by pictograms 26A and 26B provided on the outside of the skirt 24, respectively near the pin 250 when the ring 240 is in the first predetermined angular position and in the second predetermined angular position mentioned above. The pictogram 26A represents an open padlock, that is to say an unlocked configuration of the interface 200, while the pictogram 26B represents a closed padlock, that is to say a locked configuration.
    Due to the mode of assembly and disassembly of the arm 6 on the body 4, the approach stroke between the electrical contact members 112 and 212 is axial, along the axes X100 and X200 then combined, which ensures good duration life of these electrical contact members, in particular piston contacts 212.
    The invention is not however limited to the case where some of the electrical contact members are piston contacts. Lamella or "bullet tulip" or "jack" type contacts are also possible.
    As the studs 106 and the ring 240 are made of steel, they are not liable to wear out quickly during the various operations of the ring 240 and they make it possible to effectively transmit a force for bringing the plates 102A and 202A closer when screwing the ring 240 between the studs 106.
    The arm 6 is provided, at the end 62, with a notch which forms an opening 62E for balancing the pressure within the volume V6 with respect to the exterior. Indeed, depending on the operating time of the motor 8 it can heat up, as well as the control members of this motor possibly integrated into the arm
    6. Under these conditions, the temperature and pressure within the volume V6 tend to increase and the opening 62E serves as a vent. Likewise, depending on the altitude variations of the drone 2 in use, it evolves in an atmosphere whose pressure varies. The opening 62E allows balancing also in this case. In order to prevent the humidity from propagating inside the volume V6, in particular in the event of rain, this opening 62E is closed by a plug 140 mounted on the part 102.
    In practice, the part 102 comprises, within the skirt 102B, an opening 102E, this opening being surrounded by a flange 102F. The external shape of the collar 102F is adapted so that the latter comes into sealing contact against the edge of the opening 62E when the part 102 is mounted on the end 62 of the arm 6. Under these conditions, the communication between the volume V6 and the outside takes place through opening 102E, within opening 62E.
    The plug 140 is integrated into the collar 102E, to the point that it does not protrude outside the part 102 and does not risk being damaged during the manipulations of the arm 6 and during use of the drone 2 .
    The material and the structure of the plug 140 are chosen so that it is waterproof, while being porous to gas. In particular, the plug 140 can comply with the IP66 protection index of standard IEC60529 of the International Electronic Commission.
    As a variant, the number of studs 106 may be equal to one or greater than or equal to three, the number of reliefs 240C then being adapted accordingly.
    According to another variant, an internal peripheral relief, in the form of a tapping or of tapping section (s), can be provided on the internal radial surface of the locking ring 240, while a relief in the form of a thread or a section (s) of net is provided at the periphery of the nose 102D. These reliefs then respectively play the same role as the reliefs 240C and 106A mentioned above, with an inversion of the thread / tapping structures.
    In the example of the figures, the first interface 100 is mounted on the arm 6, while the second interface 200 is mounted on the zone 24 of the body 14. This has the advantage that the piston contacts 212 and the ring 240 are provided in a single copy for the different sets of arms 6 capable of being mounted on the base 4. However, as a variant, it is possible to provide the first interface 100 at the level of the zone 24 and the second interface 200 to the end 62 of arm 6.
    The embodiment and the variants mentioned above can be combined to generate other embodiments of the invention.
