This invention relates generally to vehicles and more particularly to remote control vehicles having aerial, ground and aquatic mobility capability with a combination rotor/wheel assembly.
Vehicles that have both aerial and ground mobility capability are well known and are used for many different applications, including military and police operations as well as personal use. Typically, these vehicles include both rotors (for aerial mobility) and wheels (for ground mobility) arranged in a variety of configurations.
In one such configuration, the vehicle includes two completely separate systems: a rotor system and a wheel system where power may be switched between the two systems. This type of configuration typically includes one set of motors to drive the wheels and another set of motors to drive the rotors. Unfortunately, having multiple motors is undesirable for at least three reasons: 1) multiple motors take up valuable space which not only increases the size and cost of the vehicle but also limits the power of the available motors, 2) multiple motors increase the weight of the vehicle thereby requiring motors that have enough power to lift and/or propel the entire system, and 3) having multiple motors increases the complexity of the control which has to be configured to control all of the motors simultaneously or individually.
In another such configuration, the vehicle includes an integrated rotor/wheel system, where the rotor forms part of the wheel support. For example, rotor functions as the “rim” of the wheel and when not being used for lift the rotor remains stationary. When the rotor is being used for lift the rotor rotates within the wheel cavity. As with the first configuration, the rotor system and the wheel system are basically separate and typically require separate motors. Accordingly, most if not all of the same issues present with the first configuration are present with this configuration with the addition that additional motors are required to configure the wheel/rotor combination between a horizontal configuration and a vertical configuration.
A multi-dimensional vehicle configured for aerial and ground mobility is provided and includes a vehicle body, a plurality of vehicle wheels, wherein the plurality of vehicle wheels are movably associated with the vehicle body and configurable between a ground mobility configuration and an aerial mobility configuration and a control device, wherein the control device is configured for wireless communication and is associated with the vehicle body and the plurality of vehicle wheels to controllably operate the plurality of vehicle wheels and to controllably configure the plurality of vehicle wheels between the ground mobility configuration and the aerial mobility configuration, wherein each of the plurality of vehicle wheels include a wheel rim having an inner rim circumference and a plurality of fan blades distributed along the inner rim circumference, wherein the plurality of fan blades are configured to create a flow channel between each of the plurality of fan blades and an adjacent fan blade.
A multi-dimensional vehicle configured for aerial and ground mobility is provided and includes a vehicle body, a plurality of vehicle wheels rotatably associated with the vehicle body, wherein the plurality of vehicle wheels are movably associated with the vehicle body and configurable between a plurality of mobility configurations and a control device, wherein the control device is associated with the plurality of vehicle wheels to controllably operate the plurality of vehicle wheels and to controllably configure the plurality of vehicle wheels between the plurality of mobility configurations, wherein each of the plurality of vehicle wheels include a wheel rim having an inner rim circumference and a plurality of fan blades distributed along the inner rim circumference.
A vehicle wheel for use with a multi-dimensional vehicle configured for aerial and ground mobility is provided and includes a wheel rim, wherein the wheel rim includes, a rim support structure having a rim outer structure and a rim inner structure, a rim center structure; and a plurality of rim blades, wherein the plurality of rim blades connect the rim center structure with the rim inner structure, and wherein the plurality of rim blades are configured to generate an air flow between the plurality of rim blades when the vehicle wheel is rotated.
The foregoing and other features and advantages of the present invention will be more fully understood from the following detailed description of illustrative embodiments, taken in conjunction with the accompanying drawings in which like elements are numbered alike:

The vehicle main body 102 further includes a vehicle body cover 116 which defines a body cavity 118 for containing a processing device 120 and/or control circuitry 122. As discussed hereinafter, the vehicle body cover 116 may be removably associated with the vehicle main body 102 and may be removable and/or configurable to be more aerodynamic, as desired. It should be appreciated that the vehicle body cover 116 may be associated with the vehicle main body 102 via any method and/or device suitable to the desired end purpose, such as friction fit, snap fit, clip, screws, etc.
Each of the wheel arms 114 includes a first arm portion 124 and a second arm portion 126, wherein the first arm portion 124 is connected (movably or non-movably as desired) to the vehicle main body 102 and wherein the second arm portion 126 is connected (movably or non-movably as desired) to the vehicle wheel 104. It should be appreciated that the RCV 100 further includes four (4) wheel motors 128, wherein one of each of the four (4) wheel motors 128 is associated with one of each of the vehicle wheels 104, such that the respective wheel motor 128 controllably drives (i.e. powers) the vehicle wheel 104 to cause the vehicle wheel 104 to rotate about an axis M. Additionally, the RCV 100 further includes four (4) arm motors 130, wherein one of each of the four (4) arm motors 130 is associated with one of each of the wheel arms 114 to controllably configure the second arm portions 126 between a first configuration 132 and a second configuration 134. It should be appreciated that an additional motor 127 may be included to controllably configure the second arm portions 126 between a first configuration 132/second configuration 134 and a third configuration 136 as illustrated in
This advantageously allows the arm motor 130 to controllably configure the second arm portion 126 between the X, Y and/or Z plane to go between the first configuration 132, the second configuration 134 and the third configuration 136. It should be appreciated that when the second arm portion 126 is configured into the first configuration 132, the RCV 100 is configured for ground mobility and the plurality of vehicle wheels 104 are aligned to rotate in a direction that is substantially parallel to the vehicle sides 112 (plus or minus approximately 45°) and toward at least one of the vehicle front 106 and/or vehicle rear 108 of the RCV 100. When the second arm portion 126 is configured into the second configuration 134, the RCV 100 is configured for air mobility and the plurality of vehicle wheel(s) 104 are aligned to rotate in a direction that is substantially horizontal relative to the first arm portion 114, plus or minus approximately 20°. When the second arm portion 126 is configured into the third configuration 136, the RCV 100 is configured for aquatic mobility and the plurality of wheels 104 are aligned to rotate in a direction that is substantially directed toward the vehicle sides 112 and substantially perpendicular to the vehicle front 106 and vehicle rear 108 of the RCV 100. It should be appreciated that in one embodiment, an additional arm portion may be included and the arm motor 127 may controllably configure the additional arm portion (and/or the second arm portion 126) between the first configuration 132 and/or the second configuration 134 and the third configuration 136.

When the vehicle wheels 104 are configured into the first configuration 132, the support wheels 300 are stowed to prevent the support wheels 300 from interfering with the ground mobility and/or aquatic mobility. When the vehicle wheels 104 are configured into the second configuration 134, the support wheels 300 are unstowed to support the RCV 100 when landing and sitting on the ground during the aerial mobility. It should be further appreciated that other embodiments are contemplated for supporting the RCV 100 while the RCV 100 is being configured between the first configuration 132, second configuration 134 and/or third configuration 136.
Referring to
Each of the fan blades 436 may be positioned relative to adjacent fan blades 436 such that a portion of the blade center portion 448 of one of the fan blades 436 partially overlaps the blade center portion 448 of the adjacent fan blade 436. Additionally, each of the fan blades 436 may be positioned relative to the adjacent blades 436 such that a flow channel 450 is created between each fan blade 436 and its adjacent fan blade 436. As such, when the vehicle wheels 104 are rotating, the rotation of the fan blades 436 generates an airflow into the rim front 429 through the flow channel 450 and out of the rim rear 431. When the vehicle wheel(s) 104 are configured into the second configuration 134 (i.e. rim front 429 directed toward vehicle top 110), this airflow generates lift causing the RCV 100 to have aerial mobility. Additionally, each of the vehicle wheel(s) 104 may include a tire portion 452 located along the rim outer structure 144 such that when the vehicle wheel(s) 104 are configured into the first configuration 132 (i.e. rim front 429 directed toward vehicle side 112), the tire portion 152 contacts the ground such that the when the vehicle wheels 104 rotate normally, the RCV 100 has ground mobility capability. When the vehicle wheel(s) 104 are configured into the third configuration 136 (i.e. rim front 429 directed toward vehicle front 106), this airflow generates thrust/pull causing the RCV 100 to have aquatic mobility.
Furthermore, referring to
It should be appreciated that in one embodiment, the vehicle wheels 104 include a first vehicle wheel 200 and a second vehicle wheel 202, wherein the first vehicle wheel 200 includes fan blades 140 that are configured in a clockwise configuration when viewed from the vehicle front 106 and the second vehicle wheel 202 includes fan blades 140 that are configured in a counter-clockwise configuration when viewed from the vehicle front 106. In this embodiment, the vehicle wheels 104 are configured such that one set of vehicle wheels 104 (either the first vehicle wheel 200 or the second vehicle wheel 202) are located diagonally from each other and the other set of vehicle wheels 104 (the other of either the first vehicle wheel 200 or the second vehicle wheel 202) are also located diagonally from each other. For example, a first vehicle wheel 200 may be located on the vehicle front 106 right side and the vehicle rear 108 left side and a second vehicle wheel 202 may be located on the vehicle front left side and the vehicle rear right side (or vise versa).
It should be appreciated that in another embodiment, the vehicle wheels 104 that are meant to be located one side of the RCV 100 (i.e. either right or left side) have fan blades 136 that are oriented in one direction and the vehicle wheels 104 that are meant to be located on the other side of the RCV 100 (i.e. either the left or right side) have fan blades 140 that are oriented in the opposite direction. This is because the vehicle wheels 104 on one side of the RCV 100 may be configured to rotate in one direction and the vehicle wheels 104 on the other side of the RCV 100 may be configured to rotate in the opposite direction.
It should be appreciated that
Referring to
It should be appreciated that in another embodiment, the vehicle wheels 104 may have fan blades 436 that have the same orientation and the motors may be controllably adjusted to rotate such that the fan blades 436 generate lift. As such, when the vehicle wheels 104 are configured for ground mobility (i.e. first configuration 132), the vehicle wheels 104 on one side of the RCV 100 will rotate in one direction and the vehicle wheels 104 on the other side of the RCV 100 will rotate in the opposite direction. When the vehicle wheels 104 are configured for aerial mobility (i.e. second configuration 134 and/or third configuration 136), the motors that control the rotation of the vehicle wheels 104 may be configured such that all of the vehicle wheels 104 will rotate in the direction required to generate lift (for aerial use) or forward thrust (for aquatic use).
Moreover, it should be appreciated that the vehicle body cover 108 may be configured to be easily connected to the vehicle top 110 of the vehicle main body 102 via any method and/or device suitable to the desired end purpose, such as snaps, clips, screws, Hook and Loop Fasteners, etc. It is contemplated that the invention disclosed herein may also be applied to vehicle of any size, and as such, may be implemented in vehicles having much greater sizes, such as passenger vehicles. As such, passenger vehicles may include all of the elements of the present invention or only a portion and the elements may be mixed and used as desired, such as the wheel rim 428. Referring to
