REMOTE-CONTROLLABLE FLYING PLATFORM
Description The invention relates to a remote-controllable disk-shaped flying platform that includes a platform housing, the platform housing having multiple motorized, horizontally oriented rotors.
Remote-controllable aircraft or flying platforms are known as toys, for example, wherein the aircraft as disk-shaped airborne platforms have multiple horizontally arranged rotors which are used on the one hand for ascent, and on the other hand for propulsion of the aircraft.
However, aircraft are also known which are designed as flying platforms used for industrial or military purposes. Such flying platforms, in particular for industrial purposes, have a diameter between one-half meter and one meter and greater. Such remote-controllable flying platforms, also referred to as aerial robots, when fitted with a camera on the bottom side are used for collecting information concerning the activities of groups of people, for examining structures such as houses or bridges, or for inspecting industrial facilities, in particular chemical plants. Such aircraft in the form of flying platforms have, among other elements, accelerators and gyroscopes for controlling such flying platforms.
The rotors generate vibrations which by their nature are transmitted to the housing of the flying platform. Such vibrations may lead to disturbances in the accelerators and gyroscopes, resulting in inaccurate position recognition of the flying platform, which in turn adversely affects the flight characteristics.
It has been noted above that such flying platforms are also used for taking aerial photographs or videos. In particular with regard to video recordings, vibrations of the camera are likewise disadvantageous, since blurred images may be unusable.
Accordingly, it is desirable is to provide a remote-controllable flying platform of the type stated at the outset, in which during operation of the platform the vibrations generated by the rotors have no influence on the flight characteristics of the flying platform, and also have essentially no influence on the payload, for example a camera.
In one aspect, each rotor of the remote-controllable flying platform is connected via a support arm to a support structure that accommodates the support arms of the rotors, the support structure being centrally situated in a platform housing. Also included is at least one transport housing that is vibrationally decoupled from the motorized rotors accommodated by the support structure. The transport housing accommodates devices, for example flight position recognition equipment such as accelerators and gyroscopes. This transport housing may alternatively or additionally be used for accommodating a payload, in particular a camera, for example, so that, due to the vibrational decoupling, such a camera may take recordings with little or no vibration during the flight operation.
According to one aspect of the invention, the support structure contains a vibration-damping material. It is thus clear that the vibrations that are transmitted from the motorized rotor to the support structure via the support arm are absorbed by the support structure, so that the transport housing is free or practically free of vibrations. For this purpose, the support structure may be made of a rigid foam, i.e., a vibration-absorbing material. Using such a rigid foam for manufacturing the support structure has the advantage that the support structure is extremely stiff, but due to the properties of the foam is able to absorb all or essentially all vibrations that are introduced by the support arms. It has proven to be particularly advantageous for the connection between the support structure and the respective support arm to be established using a vibration-damping material.
For example, an elastomer such as silicone may be used as the vibration-damping material, resulting in a reduction in the portion of vibrations that are actually transmitted to the support structure.
This may also be achieved by the support arm accommodating the motor of the particular rotor essentially in a vibrationally decoupled manner. On its end the support arm has a support arm head which has an essentially cylindrical design. In order to minimize the transmission of vibrations of the rotor to the support arm via the motor, the motor of the rotor is accommodated in the support arm head by means of a vibration-damping elastomer bearing, for example.
According to another aspect of the invention, the support structure is connected to the platform housing essentially in a vibrationally decoupled manner. The platform housing itself has sensors for distance recognition, for example, on the end-face side. The function of such sensors may also be impaired by vibrations. It has been pointed out above that the support structure itself is able to absorb a significant portion of the vibrations due to the use of a foam material, for example. Additional absorption of vibrations is achieved by connecting the platform housing to the support structure in a vibration-damping manner using elastomeric elements, for example.

Additional absorption of vibrations is achieved by connecting the platform housing to the support structure in a vibration-damping manner using elastomeric elements, for example.
2 According to another aspect of the invention, the support structure itself has a crown-like design, the support arms for accommodating the rotors being equidistantly distributed along the periphery of the crown-like support structure. That is, the support arms are not directly connected to one another, but instead are indirectly connected via the support structure. The generation of resonances is thus prevented here due to the decoupling of the vibrations of the support arms.
According to another aspect of the invention, the transport housing has a bowl-or pot-like design for accommodation by the support structure. As stated above, this bowl- or pot-like transport housing, which for weight savings may also have a skeletonized design, for example, may contain on the one hand the electrical and electronic devices, for example flight position recognition equipment such as accelerators and gyroscopes, and on the other hand the load, such as a camera. A further advantage of using a transport housing in the form of a bowl or pot is that the rigidity of the support structure itself is thus increased. As a result, the platform housing essentially does not have to have inherent stability, so that the platform housing may have a lightweight design.
The bowl- or pot-like transport housing is advantageously situated on the bottom side of the flying platform, which has advantages with regard to the center of gravity of the flying platform as such. Located on the top side of the support structure is a flat cover, which together with a base forms a housing chamber. The base may be an integral part of the platform housing, in particular the top shell of the platform housing having a two-shell design.
This housing chamber is used, for example, for accommodating the battery. In addition, to a certain extent the cover also provides reinforcement of the support structure, similar to the transport housing which is oppositely situated on the bottom side of the support structure. At least three legs by means of which the flying platform rests on the ground are situated on the support structure or also on the transport housing.
The platform housing itself has a disk-shaped design, and is provided with recesses for the rotors, corresponding to the number of rotors. The platform housing also has a closed contour on the end-face side. The advantage of a platform housing that is closed on the end-face side is that the rotors are thus protected. That is, if such a platform strikes objects during flight, this does not automatically cause damage to the rotors. In addition, the risk of injury to persons from the high-speed rotors in the event of contact with such a flying platform is reduced. Sensors for determining the distance of the flying platform from other objects are distributed over the periphery on the end face of the closed contour of the platform.
According to another aspect of the invention, the transport housing has a bowl-or pot-like design for accommodation by the support structure. As stated above, this bowl- or pot-like transport housing, which for weight savings may also have a skeletonized design, for example, may contain on the one hand the electrical and electronic devices, for example flight position recognition equipment such as accelerators and gyroscopes, and on the other hand the load, such as a camera.

As a result, the platform housing essentially does not have to have inherent stability, so that the platform housing may have a lightweight design.

In addition, the risk of injury to persons from the high-speed rotors in the event of contact with such a flying platform is reduced. Sensors for determining the distance of the flying platform from other objects are distributed over the periphery on the end face of the closed contour of the platform.
3 The recesses for the rotors are situated in the edge region of the platform housing.
The contour of the platform housing, which is closed on the end-face side, follows the configuration of the recesses for the rotors in the platform housing in an undulating manner.
In conjunction with the recesses for the individual rotors, this results in a skeletonized platform housing which thus has a weight-saving design.
The platform housing, as stated, may be composed of a top shell and a bottom shell, which in combination form a stable structure due to the fact that the top shell and bottom shell form a housing.
The invention is explained in greater detail by way of example with reference to the drawings.

The flying platform, denoted overall by reference numeral 1, has a total of six circular recesses 2 for the rotors, denoted by reference numeral 5. Each rotor includes a motor 6 which is accommodated by the support arm head 10 of the support arm 11 in a vibration-damping manner, for example by means of elastomeric elements. The support arm head 10 has a base 12 on which an elastomer pad 10a for accommodating the motor 6 is situated.
Each support arm 11 is held by the support structure, denoted overall by reference numeral 20. The support structure 20 is illustrated as a crown- or ring-shaped structure, the support arm structure 20 having shell-shaped recesses 13 and flange-shaped projections 21 in the area of the transition to the support arms 11 for enlarging the contact surface for the support arms. The support arms 11 are accommodated by the support structure 20 in the area of the projections 21.
The configuration of the support arms 11 on the support structure 20 is shown in detail in Figures 3 through 5. Figure 3 shows that the support structure 20 has a shell-shaped recess 25 for accommodating the support arms 11 in the area of the flange-shaped projections 21.

The flying platform, denoted overall by reference numeral 1, has a total of six circular recesses 2 for the rotors, denoted by reference numeral 5. Each rotor includes a motor 6 which is accommodated by the support arm head 10 of the support arm 11 in a vibration-damping manner, for example by means of elastomeric elements. The support arm head 10 has a base 12 on which an elastomer pad 10a for accommodating the motor 6 is situated.
Each support arm 11 is held by the support structure, denoted overall by reference numeral 20. The support structure 20 is illustrated as a crown- or ring-shaped structure, the support arm structure 20 having shell-shaped recesses 13 and flange-shaped projections 21 in the area of the transition to the support arms 11 for enlarging the contact surface for the support arms. The support arms 11 are accommodated by the support structure 20 in the area of the projections 21.
The configuration of the support arms 11 on the support structure 20 is shown in detail in Figures 3 through 5. Figure 3 shows that the support structure 20 has a shell-shaped recess 25 for accommodating the support arms 11 in the area of the flange-shaped projections 21. Situated between the top side of the shell-shaped recess and the support arm 11 is an elastomer material 26, for example in the form of a pad, which may be adhesively bonded on the one hand to the shell-shaped recess in the support structure 20, and on the
5 other hand to the support arm. However, it is also conceivable to use a silicone adhesive to bond the support arm 11 directly in the shell-shaped recess 25 in the support structure 20.
The use of such an elastomer pad, or also adhesive bonding using a silicone adhesive, for example, reduces the transmission of vibrations from the support arm in the support structure. For securely fastening the support arm 11 in the shell-shaped recess 25 in the support structure, a tab 28 may be provided on the top side which rests against the top side of the support arm above the elastomer pad 26 and which is situated on the support structure. The support structure 20 may likewise be arranged on the platform housing using elastomer pads 8.
The bowl- or pot-like transport housing 30 is situated on the support structure 20.
Gyroscopes or accelerators (not illustrated), for example, which are necessary for controlling the flying platform during flight operation are supported in the transport housing 30. In addition, the transport housing has means in the form of threaded bushings 31, for example, for mounting a camera (not illustrated). Located on the top side of the flying platform is a cover 35 which in conjunction with a base, which may be provided by means of an indentation in the platform housing, forms a housing chamber 38 which is used, for example, for accommodating a battery 36. The individual electric motors 6 for the rotors 5 are supplied with power via the battery 36. However, it is also conceivable to situate the battery directly at the cover 35.
As described above, the flying platform 1 also includes a platform housing 7.
The platform housing includes a top shell and a bottom shell 7a, 7b, respectively, which are joined together, in particular adhesively bonded. In this manner the platform housing acquires inherent stability which is further reinforced by the support structure. The platform housing 7 is connected, for example, adhesively bonded, to the support structure. It is apparent that the disk-shaped platform housing 7 is closed all around on the end-face side (arrow 50). In conjunction with the recesses 2 for the rotors 5 and the end-face curvature of the platform housing around the recesses 2, this results in a skeletonized design of the platform housing. That is, for reasons of weight savings, only enough material remains at the platform housing between the individual recesses as is necessary on the one hand for the stability of the platform housing in connection with the support structure 20, and on the other hand for the formation of the closed contour on the end-face side. Such a closed contour has several advantages: for one, the rotors are protected if objects are inadvertently struck during the flight operation, and in addition humans are protected from the rotors in the event of
The use of such an elastomer pad, or also adhesive bonding using a silicone adhesive, for example, reduces the transmission of vibrations from the support arm in the support structure. For securely fastening the support arm 11 in the shell-shaped recess 25 in the support structure, a tab 28 may be provided on the top side which rests against the top side of the support arm above the elastomer pad 26 and which is situated on the support structure. The support structure 20 may likewise be arranged on the platform housing using elastomer pads 8.

Such a closed contour has several advantages: for one, the rotors are protected if objects are inadvertently struck during the flight operation, and in addition humans are protected from the rotors in the event of
6 accidental contact with the aircraft during operation. This is particularly true in light of the high rotational speed of the rotors.
In this regard it is pointed out that the stability is provided not only by the support structure 20, but also by the bowl- or pot-like transport housing 30 situated on the support structure, since this bowl- or pot-like transport housing 30 provides for an increase in the torsional rigidity of the crown- or ring-shaped support structure 20. The cover 35, which is situated on the top side of the support structure 20, functions in a similar manner.
Three legs 32 by means of which the flying platform 30 rests on the ground are situated on the transport housing 30.
Sensors 45 which are used for determining the lateral distance of the flying platform from objects during the flight operation are situated at the end-face side of the platform housing.
The scope of the claims should not be limited by particular embodiments set forth herein, but should be construed in a manner consistent with the specification as a whole.
