The invention consist in a mechanical holding system structure that holds the engines, and other equipment, of a remote controlled and Unmanned Aerial Vehicle - U.A.V., otherwise usually called drone. The innovation regards a supporting structure of a radio controlled multirotor.
The vehicle includes a number of propeller engines, that achieve a propelling force used to take off and fly in any direction. The vehicle is remote controlled using a remote control unit, used to control the vehicle along the expected directions and trajectories.
From the State of the art, remote-controlled aerial vehicles Multirotor are known. They generally consist of a mechanical structure, or frame, where a series of propeller engines are integrated, in order to obtain enough driving force to fly. Considering that this kind of vehicles are controlled remotely, they require some electronic devices that detect physical measurements of position and orientation in order to fly properly and to receive remote control signals of direction, trajectory, speed and flight altitude.
This electronic device must be installed on the same vehicle, and usually the weight and the number of components used affects significantly the location of the center of mass of the vehicle and therefore on the dynamics of flight.
Nowadays some attempts have been proposed in order to optimize the distribution of weights and to avoid additional forces affecting negatively on the trajectory. Mainly, it has been proposed to install all the engines in a symmetrical configuration in respect to the vertical axis of the vehicle.
For this reason, the multirotor aerial vehicles usually have four-rotors, so called quad- copters, having the engines placed symmetrically to the main axis.
Therefore, the main objective of the present invention is to propose a mechanical holding system for multirotor's engine and other equipment of a radio controlled multirotor. The same structures including all the typical elements of an Unmanned Aerial Vehicle - UAV, like in example the rotor engines, the electronic control unit, the sensors, the battery and the radio transmission means from/to a remote controlling unit.
Another objective is that all said functional components, that are the rotor engines, the electronic control unit, the sensors, the battery and the radio transmission means from/to a remote controlling unit, could be installed at the center of the structure, in such a way that the center of mass is contained exactly in the geometric center of the same structure, and said vehicle, or radio controlled multirotor, can achieve some more stable and easily controllable flight dynamics.
Another further objective is that the mechanical structure could be a basis element, or module, belonging to a more complex modular structure. Therefore, the larger structure would be composed by one or more smaller structures placed according to a geometric configuration on the same plane, having engines in a radial position, otherwise placed each on the other, having engines in a coaxial position, so that more complex vehicles could be achieved, like in example a four-rotors craft, a six-rotors craft, a eight-rotors-craft, etc.
Another further objective is that the structure includes protection elements so that either the propellers, connected to said engines, and the electronic controlling elements are protected from the possible impact with external objects and agents.
Another further objective is that the structure includes adds-on particularly useful in case of emergency or malfunctioning during the flight of the vehicle, in order to avoid damage by a falling to the ground.
Therefore, it is specific subject of the present invention a mechanical structure, mechanical holding system for multirotor's engine and other equipment of a remote controlled and Unmanned Aerial Vehicle - UAV, and more exactly of a radio controlled multirotor, characterized in that comprising:
a series of basic elements, each of them being composed by at least three respective circular elements which are connected each other on a central element; said basic elements being placed one on the other, having their perimeter jointed by transversal jointing elements, in order to achieve a unique block; in the central part of each circular element a supporting element is installed, embedding a rotating propeller, said supporting element being composed by a central ring, on which a respective engine is fixed, and said central ring is connected to a respective circular element by radial arms,
so that the entire mechanical structure includes all the typical elements belonging to an Unmanned Aerial Vehicle - UAV, like in example the rotor engines, the electronic control unit, the sensors, the battery and the radio transmission means from/to a remote controlling unit.
The present invention will now be described for illustrative but not limitative purposes, according to its preferred embodiments, with particular reference to figures of the enclosed drawings, wherein:

It is here underlined that only few of the many conceivable embodiments of the present invention are described, which are just some specific non-limiting examples, having the possibility to describe many other embodiments based on the disclosed technical solutions of the present invention. In the different figures the same elements are indicated by the same reference numbers.
Figure 1 shows a mechanical structure 100, holding system for multirotor's engine and other equipment of a remote controlled and Unmanned Aerial Vehicle - UAV, in a open configuration, according to the present invention.
It substantially includes a series of basic elements 101 a, 101 b, 101 c, each of them, like in example said element 101 a, being composed by at least three respective circular elements 102a, 103a, 104a, which are connected each other on a central element 105b. The basic elements 101 a, 101 b, 101 c are placed one on the other, having their perimeter jointed by transversal jointing elements 112, in order to achieve a unique block.
In the central part of each circular element 102a, 102b, 102c a supporting element is installed, embedding a rotating propeller. Said supporting element being composed by a central ring 110, 111 , on which a respective engine is fixed, and said central ring 110, 111 is connected to a respective circular element by radial arms 114, 115.
In such a way, the entire mechanical structure 100 includes all the typical elements belonging to an Unmanned Aerial Vehicle - UAV, like in example the rotor engines, the electronic control unit, the sensors, the battery and the radio transmission means from/to a remote controlling unit.
All the functional components are installed on said central element 105b, like in example, the electronic control components, the sensors, the battery, and the radio transmission means from/to a remote controlled system. In such a way, the center of mass of the mechanical structure 100 is contained exactly in the geometric center of the same structure 100, and said vehicle, or radio controlled multirotor, achieves some more stable and easily controllable flight dynamics.
Figure 2 shows a mechanical structure 200, holding system for multirotor's engine and other equipment of a remote controlled and Unmanned Aerial Vehicle - UAV, in a closed configuration, according to the present invention.
Said structure 200 further includes a protection net 108 installed on the upper part of said circular elements 102a, 103a, 104a of the respective basic element 101 a, and on the lower part of said circular elements 102c, 103c, 104c, of the respective basic element 101 c. In such a way, the propellers connected to said engines can be protected, in respect to possible contact with external objects and agents.
Furthermore, the same structure can include further protection elements, placed on the outer border of said circular elements 102a, 103a, 104a, of the respective basic elements 101 a, 101 b, 101 c. In such a way, either the propellers, connected to said engines, and the central element 105b, where the electronic controlling elements, the sensors, the battery and the radio transmission means are installed, are protected from the possible impact with external objects and agents.
A fundamental characteristic of the present invention is represented by its modularity. In fact, the mechanical structure 100 can be a basis element, or module, belonging to a more complex modular structure.
The larger structure can be composed by one or more smaller structures 100 placed according to a geometric configuration on the same plane, having engines in a radial position, otherwise placed each on the other, having engines in a coaxial position, so that more complex vehicles can be achieved, like in example a four-rotors craft, a six- rotors craft, a eight-rotors-craft, etc.
Furthermore, the mechanical structure 100 of the present invention can include some adds-on, particularly useful in case of emergency or malfunctioning during the flight of the vehicle, in order to avoid damaged by a falling to the ground. One add-on is represented by a parachute device that, in case of emergency, is able to open a parachute automatically or by command, in order to slow down the falling of the mechanical structure 100 to the ground, avoiding that it can be damaged by the impact to the ground.
Another add-on is represented by a pneumatic inflatable band, where air and/or a proper gas, like helium, are pushed inside. This band can be directly installed and connected to the outer border of the same mechanical structure 100 by using proper connection means.
The material by which the mechanical structure 100 is made, completely or in its components, can be a metallic material, or a plastic material, or a composite material like carbon fiber or fiberglass, or further a natural material like wood, having proper characteristics of lightness and robustness.
Therefore, the above examples show that the present invention achieves all the proposed objectives. In particular, it permits to obtain a mechanical holding system for multirotor's engine and other equipment of a radio controlled multirotor. The same structures includes all the typical elements of a Unmanned Aerial Vehicle - UAV, like in example the rotor engines, the electronic control unit, the sensors, the battery and the radio transmission means from/to a remote controlling unit.
Furthermore, all said functional components, that are the rotor engines, the electronic control unit, the sensors, the battery and the radio transmission means from/to a remote controlling unit, are installed at the center of the structure, in such a way that the center of mass is contained exactly in the geometric center of the same structure, and said vehicle, or radio controlled multirotor, achieves some more stable and easily controllable flight dynamics.
Further according to the invention, the mechanical structure represents a basis element, or module, belonging to a more complex modular structure. Therefore, the larger structure is composed by one or more smaller structures placed according to a geometric configuration on the same plane, having engines in a radial position, otherwise placed each on the other, having engines in a coaxial position, so that more complex vehicles are achieved, like in example a four-rotors craft, a six-rotors craft, a eight-rotors-craft, etc.
