    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF INVENTION

    [0037] Hereinafter, a charging connection device for a drone according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG. 1 is a view illustrating an example in which a drone charging connection device according to an embodiment of the present invention is installed in a drone; FIGS. 2 to 4 are views illustrating the configuration of the drone charging connection device according to an embodiment of the present invention, specifically including an assembly view, a side cross-sectional view in an assembled state, a front cross-sectional view in an assembled state, and an exploded view; FIG. 6 is a view illustrating the configuration of a tension unit in the drone charging connection device according to an embodiment of the present invention; and FIG. 7 is a view illustrating the operation of the drone charging connection device according to an embodiment of the present invention.

    [0038] The drone charging connection device according to an embodiment of the present invention may include a core 20, a current carrying member 30 and a tension unit 40.

    [0039] The core 20 may be provided on a drone 10, and more specifically, may be mounted on a landing skid 12 of the drone 10.

    [0040] That is, the core 20 may be mounted on a component that is grounded when the drone 10 lands.

    [0041] In the embodiment of the present invention, the core 20 may be formed in a cylindrical shape, but is not limited thereto, and the shape may vary depending on a shape of the landing skid 12.

    [0042] The current carrying member 30 may be disposed on an outer periphery of the core 20 and may be made of an electrically conductive material. The current carrying member 30 may be made of copper, aluminum, copper alloy, aluminum alloy, or the like, so that electricity can easily pass while maintaining rigidity.

    [0043] Meanwhile, as shown in FIG. 2, an electric wire 14 may be connected to one side of the current carrying member 30, and the electric wire 14 may be connected to a battery charging circuit of the drone 10.

    [0044] The tension unit 40 may be disposed between the core 20 and the current carrying member 30, and may absorb an impact transferred from the current carrying member 30.

    [0045] In more detail, when attempting to land the drone 10, the current carrying member 30 may be firstly grounded and, at this time, an impact possibly occurring due to a descending speed of the drone 10 may be absorbed by the tension unit 40.

    [0046] On the other hand, the drone 10 may land at a station 50 and may be ready for takeoff. The station 50 may be provided with a current carrying plate 52 as shown in FIG. 1.

    [0047] That is, with regard to the drone charging connection device according to an embodiment of the present invention, when the drone 10 lands on the station 50 or is ready for takeoff, the current carrying member 30 may be placed on the current carrying plate 52, and thus, a circuit of the current carrying member 30 and the current carrying plate 52 may be closed.

    [0048] Therefore, with regard to the drone charging connection device according to an embodiment of the present invention, power may be supplied from the current carrying plate 52 to the current carrying member 30.

    [0049] That is, the drone charging connection device according to an embodiment of the present invention may allow a battery to be charged while the drone 10 is ready for takeoff; precisely control a landing location when landing is attempted; and safely land the drone at a desired charging position even with roughly controlling.

    [0050] Further, the drone charging connection device according to an embodiment of the present invention may allow the drone 10 to attempt landing without excessively reducing a speed in the sky above the landing point when landing is attempted.

    [0051] Further, with regard to the drone charging connection device according to an embodiment of the present invention, a contact point for power connection may be pressed by the weight of the drone itself, resulting in a more complete form of contact point, so that spark splashing due to a contact failure during charging can be prevented.

    [0052] Further, as shown in FIGS. 4, 6 and 7, the tension unit 40 may be provided in plurality, and may be disposed in a circular form around an outer periphery of the core 20.

    [0053] Accordingly, when an impact is applied to the current carrying member 30 from the outside, it is possible to absorb the impact in all directions regardless of which direction the impact is applied from.

    [0054] In addition, as shown in FIG. 6, mounting holes 22 may be formed concavely on an outer surface of the core 20 in a number corresponding to the number of the tension units 40 so as to align the tension units 40 thereon.

    [0055] That is, the plurality of tension units 40 may be disposed at predetermined positions as intended by the designer, and it is possible to inhibit the tension units from arbitrarily departing from the predetermined positions.

    [0056] Further, the tension unit 40 may be provided in a form in which a coil 44 is provided on one side of the head 42 as shown in FIG. 4 and, when the head 42 is placed in the mounting hole 22, it may contribute to alignment of a posture of the coil 44. As a result, the coil 44 may maintain the posture in contact with the current carrying member 30 in a normal line. Further, a load applied to the landing skid 12 when the drone 10 is landing may be delivered to a direction in which the coil 44 contracts, thereby more perfectly contributing to shock absorption or shock mitigation.

    [0057] Further, the head 42 may be fixed while being press-fitted into the mounting hole 22, or may be fixed with an adhesive.

    [0058] Further, among the plurality of tension units 40, as shown in FIG. 4, with respect to the cross line CL passing through the center of the core 20, the tension units 40 below the cross line CL may be subjected to compressive stress so as to transfer the weight of the drone 10 to the current carrying member 30.

    [0059] That is, the weight of the drone 10 may entirely contribute to keeping the current carrying member 30 and the current carrying plate 52 in close contact, thereby more reliably preventing contact failure.

    [0060] Further, as shown in FIG. 7, when the current carrying plate 52 is provided in a concave shape rather than a flat shape, the current carrying member 30 may contact the current carrying plate 52 at two points. Further, due to the weight of the drone 10, the current carrying member 30 may be pressed to the current carrying plate 52 through the plurality of tension units 40 disposed below the cross line CL, thereby preventing a contact failure problem.

    [0061] A plurality of the current carrying members 30 may be provided as shown in FIGS. 2 and 3, and may be sequentially disposed on a single core 20. That is, one current carrying member 30 and another current carrying member 30 adjacent thereto may move physically independently to each other.

    [0062] Accordingly, even if one of the current carrying members 30 is deformed for an unknown reason, another current carrying member 30 still may contact the current carrying plate 52.

    [0063] That is, the drone charging connection device according to an embodiment of the present invention can prevent charging failure when charging is attempted.

    [0064] Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains will understand that the present invention may be embodied in other specific forms without changing the technical spirit or essential characteristics thereof.

    [0065] Therefore, the embodiments described above are to be understood as illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the appended claims, and all changes or modifications which are derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention.
