    专利说明:

    [0001] The invention relates to drones, especially rotary-wing drones such as quadcopters. These drones comprise a drone body and a plurality of propulsion units mounted at the end of the link arm to the body of the drone, each propulsion unit being provided with a propeller driven by an individual motor. The different engines are controllable in a differentiated way to pilot the drone in attitude and speed. In some configurations, it may be advantageous to provide the drone with an accessory, mounted on the body of the drone removably.
    [0002] In the remainder of the description, an example of a drone accessory will be described as an assembly formed of a shaft provided at each of its ends with a wheel of large diameter. The shaft is oriented transversely to the main direction of evolution of the drone and the wheels have a diameter greater than the maximum overall dimension of the drone with its propellers. This configuration makes it possible in particular to make not only fly the drone but also, equipped with its wheels, to roll this drone on the ground, along a wall, against a ceiling, etc., thus multiplying the possibilities of evolution , in addition to the usual configurations of free flight and lift of the drone.
    [0003] This example should however be considered in no way limiting, because as will be understood the invention applies to the assembly of a very large number of accessories on the body of the drone. It may thus be advantageous to provide the drone with floats mounted at the end of the transverse shaft, so as to allow the drone to land on a body of water and move on it safely. It may also be accessories that do not use a support shaft, for example a removable auxiliary camera mounted on the back of the drone, etc. In any case, it is desirable to be able to assemble and disassemble this accessory easily, quickly, and without any tools. The fastening system must also allow complete attachment of the accessory and the drone, these two elements to form a one-piece assembly when the accessory is locked on the body of the drone.
    [0004] In particular, in the case of a transverse shaft attached to the drone, it is important to prevent any axial translation of the shaft, which could cause a lateral displacement of the wheels with the risk of coming into contact with the propellers of the drone. drone.
    [0005] The object of the invention is to provide a quick attachment system of an accessory on a drone body that meets these requirements of ease of use and reliability of the mechanical connection between drone and accessory. On the other hand, to the extent that it is desired to use this fastening system with consumer drones, toys, etc., it should use a system that can be easily industrialized in large series and very low cost , while meeting the criteria of simplicity and reliability outlined above. The quick-release system must also be universal in character, that is, it must be able to be used to attach a wide variety of different accessories to a single drone without the need for an adapter. or other additional element depending on whether the user wishes to mount such or such accessory on his drone. To achieve the above aims, the invention proposes for this purpose an assembly comprising a drone and a drone accessory adapted to be removably attached to the body of the drone. Characteristically, the invention proposes a quick attachment system for the accessory on the drone body, comprising a connecting piece integral with the accessory, and a support frame formed on the drone body, this frame being adapted to cooperate with the connecting piece to allow the mounting, positioning and holding in place of the accessory on the drone body. The connecting piece is rotatable relative to the frame between a free position, where the connecting piece can be freely placed on the frame or disassociated from the frame, and a locked position, where the connecting piece is locked. in rotation and in translation on the frame so as to form therewith a one-piece assembly. The connecting piece comprises a tubular element defining at least one trunnion adapted to cooperate with a bearing homologous to the frame, this bearing being a semi-cylindrical bearing with an opening facing outwards to allow the positioning of the trunnion. the connecting piece.
    [0006] The connecting piece also comprises a lever extending perpendicularly to the tubular element with the trunnion disposed in the vicinity of the lever at the proximal end of the lever, means for rotating stop of the connecting piece relative to the frame defining the locked position, locking means in axial translation of the connecting piece relative to the frame when the connecting piece is in the locked position, and means for clipping the connecting piece on the frame once the locked position reached. According to various advantageous subsidiary characteristics: the means of rotating abutment comprise on the frame a projection formed near the bearing and having a face turned in a direction opposite to that of the openings of the bearings, and on the connecting piece, a abutment face coming into contact and bearing against the face of the projection of the frame once the locked position reached; - The locking means in axial translation comprise on the connecting piece at least one shoulder formed on the tubular body near the journals, and on the frame of the abutment faces extending radially the semi-cylindrical bearing and bearing against the shoulder of the connecting piece; the clipping means of the connecting piece on the frame once the locked position has been reached comprises a boss formed at the distal end of the lever and a cooperating recess formed in a homologous region of the frame, or vice versa; the lever is elastically deformable along its length so as to allow, by a pressure exerted transversely with respect to this length, to move the boss away from the recess and thus to allow unclipping of the connecting piece and the frame and rotation; consecutive of the connecting piece from the locked position to the free position; - The accessory comprises a shaft secured to the connecting piece and extending axially relative to the tubular body on either side thereof, this shaft can include carrying wheels at each of its ends. An embodiment of the invention will now be described with reference to the appended drawings in which the same references designate elements that are identical or functionally similar from one figure to another. Figure 1 is an overall view, in perspective, of a drone equipped with an accessory constituted, in the illustrated example, a pair of side wheels. Figures 2a and 2b are enlarged views of the central portion of the drone of Figure 1 equipped with its accessory, showing the quick fastening system, respectively in the initial position of installation of the accessory and in the final locked position . Figure 3 shows in more detail the constituent elements of the quick fastening system, with the connecting piece and the homologous support frame, formed on the body of the drone. Figure 4 is an isolated view of the connecting piece, taken at an angle different from that of Figure 3. Figures 5a and 5b are side views showing, respectively in the initial position and locked end position, the piece of link and the cooperating support frame. FIG. 1 shows an assembly comprising a quadrocopter type drone with a central body 12 from which four support arms 14 radiate. Each support arm 14 is equipped at its distal end with a propulsion unit. 16 comprising a motor driving in rotation a propeller 18 extending in a horizontal plane above the support arm 14. The drone 10 is provided with an accessory formed of two lateral wheels 20 of large diameter (diameter greater than overall dimension of the drone with its propellers), extending in planes parallel to the main direction A of evolution of the drone, and disposed on either side of the drone body 12 and the propulsion units 16 and propellers 18. The wheels 20 are carried by a transverse shaft 22, which is mounted on the drone body 12 so as to be integral therewith in translation and in rotation (that is to say that the shaft 22 can not move axially or turn around. r himself). The wheels 20 are freely rotatably mounted at the end of the shaft 22, each of the two wheels can therefore rotate independently of the other and is therefore purely passive. The wheels 20 have no training role, they are only used to allow the drone to remain at a distance from the ground or a wall while remaining in contact with the ground or the wall. The drone, driven by the only force of its propellers, can then roll on this ground or this wall. The shaft 22 is advantageously mounted on the back of the drone, so that the center of gravity of the latter is below the shaft 22, and therefore below the center of rotation of the wheels 20, which will allow a natural return to equilibrium whatever the conditions of sustenance. Figures 2a and 2b illustrate in more detail how the shaft 22 is mounted on the drone body 12.
    [0007] This assembly is carried out by means of a quick fastening system, characteristic of the invention, comprising a connecting piece 24 cooperating in a removable manner with a frame 26 integral with the drone body 12. The connecting piece 24 is integral with in rotation and in translation of the shaft 22, and it can be placed in the frame 26 (position shown in Figure 2a). The connecting piece 24 may in particular be overmolded directly on the shaft 22 so as to make these two elements integral both in rotation and in translation, without any relative degree of freedom. The locking of the connecting piece 24 on the frame 26, and therefore the locking of the drone accessory (materialized in this case by the shaft 22) on the drone body 12, is obtained by rotation between: - a initial position, illustrated Figure 2a, where the connecting piece 24 can be freely placed on the frame 26 (or dissociated thereof), and - a locked position, illustrated in Figure 2b, where the connecting piece 24 is blocked in rotation and in translation on the frame 26 so as to form therewith a one-piece assembly, without relative degree of freedom. The transition from the initial position to the locked position is operated by a simple rotation of a fraction of a turn (about 60 to 90 °), shown schematically by the arrow 28 in Figure 2a. Mounting and locking the accessory on the drone body is therefore limited to the establishment of the connecting piece 24 on the frame 26 and the rotation according to the arrow 28, without further manipulation necessary. Figures 3 and 4, as well as Figures 5a and 5b, illustrate in more detail the constituent elements of the connecting piece 24 and the support frame 26 to achieve the desired results. The connecting piece 24 comprises a tubular element coaxial with the shaft 22 (shaft not shown in Figures 3 and 4), defining two journals 30 intended to abut against homologous bearings 32 of the support frame 26. These bearings 32 are open upwards, the opening 34 (Figures 5a and 5b) being sufficiently wide to allow the establishment and removal of the pins 30 of the connecting piece 24 in the free initial position (position shown in Figures 2a, 3 and 5a). The support frame 26 also comprises a central rib 36 perpendicular to the axis of the trunnions 30 and two lateral ribs 38, the bearings 32 being formed in the ribs 38. The central rib 36 and the lateral ribs 38 define two pairs of parallel flat faces 40, 42 for guiding and housing a respective shoulder 44 formed on the tubular body of the connecting piece 24. Each shoulder 44 has abutment faces 46, 48 coming into contact respectively with the faces 42 lateral ribs 38 and 40 of the central rib 36. This configuration allows, once the connecting piece 24 has been placed in the support frame 26 with the journals 30 in the bearings 32, to immobilize in axial translation the connecting piece 24, and thus the shaft 22 and generally the drone accessory, relative to the body 12 of the drone. The shoulders 44 further comprise, as shown in Figures 5a and 5b, an end region 50 terminating in a face 52 forming an abutment face, for example a planar face extending in a radial plane. This abutment face 52 is intended to come into contact with a counter-facing homologous contact face 54 formed on a projecting flange 56 of the support frame 26. In the free initial position (FIG. 5a), the two faces 52 and 56 are remote, and the rotation (arrow 28) to the locked position comes to put these faces in contact and abutment, preventing any output of the journals 30 out of the bearings 32.
    [0008] To maintain the connecting piece 24 in the locked position (that is to say the position of Figure 5b), the connecting piece 24 comprises a lever 58 extending radially relative to the tubular member carrying the pins 30 This lever 58 is provided at its end with a boss 62 intended to cooperate with a homologous recess 64 formed in the central rib 36 of the support frame 26, the boss 62 being formed on one of the lateral faces of the lever 58 in the vicinity of its distal end 60. Due to the elasticity of the material of the lever, which is for example made of plastic, the boss / recess assembly 62, 64 is a clipping means resistant to various external stresses, vibrator - tions, etc. which could urge the connecting piece 24 in the direction of the opening in the absence of any maneuver of the user. The assembly connecting piece / support frame 24, 26, and thus the entire body of drone / accessory remains well secured once the lever 58 has been lowered until the boss 62 comes clipping into the recess 64. To dismount the accessory, it is sufficient for the user to exert a transverse stress on the lever, for example by means of a spout 64 formed at the end 60, this maneuver being illustrated by arrow 62 in Figure 2b. This bias, because of the elasticity of the lever, will have the effect of moving the boss 62 away from the recess 64 and will thus unlock the lever 58 from the support structure 26, thus allowing a reverse rotation of the connecting piece to the free position where the accessory can be easily removed.
