2. The plug-and-play multifunctional attachment device of the remote control rotorcraft according to claim 1, wherein the device board comprises at least one light emission element mounted to and electrically connected to the bottom surface thereof so that when the remote control device transmits the signal to the remote control receiver unit, the light emission element is caused to give off light.

3. The plug-and-play multifunctional attachment device of the remote control rotorcraft according to claim 1, wherein the device board further comprises a switch element electrically connected thereto.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

(9) Referring to FIG. 1, the present invention provides a plug-and-play multifunctional attachment of a remote control rotorcraft, which comprises: an attachment body 10 and a second coupling member 20, of which components and/or parts and spatial relationships thereof will be described in detail in the following.

(10) Referring to FIG. 2, the attachment body 10 comprises a device board 11, which may include a circuit board or is a circuit board itself, and a remote control receiver unit 12. The device board 11 has a top surface to which a first coupling member 13 is mounted. The remote control receiver unit 12 is mounted to and electrically connected to a bottom surface of the device board 11. A remote control device 30 may be used for transmission of wireless or radio signals, in a wireless manner, with the remote control receiver unit 12.

(11) Referring to FIGS. 1 and 2, the device board 11 of the attachment body 10 further comprises a dropping mechanism 14 and a power unit 15 mounted to the bottom surface thereof The dropping mechanism 14 comprises a slidable bar 141 and a retainer member 142. The slidable bar is coupled to the power unit 15 to have the slidable bar 141 reciprocally movable. The retainer member 142 has an end pivotally connected to the dropping mechanism 14 and an opposite end set in retained engagement with the slidable bar 141.

(12) Further, the device board 11 may also comprise at least one light emission element 16 and a switch element 17 mounted to and electrically connected with the bottom surface thereof When the remote control device 30 transmits a signal to the remote control receiver unit 12, the light emission element 16 is activated to give off light. The switch element 17 is provided for activating or de-activating the operation of the attachment body 10.

(13) Referring to FIG. 3, the second coupling member 20 is provided for being mounted to or coupled to a bottom of an unmanned aircraft 40 (which is the remote control rotorcraft) for enabling coupling engagement and connection between the second coupling member 20 and the first coupling member 13. In the instant embodiment, the first coupling member 13 and the second coupling member 20 are generally and respectively in the form of a male buckling part and a female buckling part, which enable releasable and removable coupling therebetween.

(14) Referring to FIGS. 4 and 5, in use, the retainer member 142 provides a function for suspending and thus retaining an object A thereon. The remote control device 30 may be operated to cause the slidable bar 141 to move into retaining engagement with and coupling with the retainer member 142 so that the object A is suspended and retained on the retainer member 142. When the unmanned aircraft 40 has flown to a desired location and a desired height, the remote control device 30 may be operated to transmit a signal to the remote control receiver unit 12 to have the power unit 15 drive the slidable bar 141 to move in such a way that the retainer member 142 disengages from the slidable bar 141 to allow the object A to drop. This may be used in dropping supply for rescue, execution of rescue in water areas, and dispatching marine rescue equipment in an air-dropping manner.

(15) Referring to FIGS. 6 and 7, a second embodiment of the present invention is illustrated, which has a structure similar to that of the previous embodiment so that description of the similar parts will be omitted and only the illustration of the different parts will be given below.

(16) In the instant embodiment, a lifting mechanism 18 is used to replace the dropping mechanism 14 of the previous embodiment. The lifting mechanism 18 is mounted to the bottom surface of the device board 11. The lifting mechanism 18 comprises an axle 181 and a cable 182. The axle 181 is coupled to the power unit 15. The cable 182 has an end coupled to the axle 181 and wound around the axle 181. An opposite end of the cable 182 is provided with a hook 183 or a ring (not shown) connected thereto.

(17) The cable 182 provides a function of being coupled to an object A so that when the remote control device 30 transmits a signal to the remote control receiver unit 12, the power unit 15 is caused to drive the axle 181 to rotate to have the cable 182 descend to lower down the object A or to lift up the object A.

(18) It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

(19) While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
