This invention relates to a solar wing, and more particularly, to a system and method for modifying the position of a solar wing to maximize downforce and optimize solar energy absorption.
A wing can generally be described as an elongated object with a shape that will produce an aerodynamic force when air passes by it. An airfoil can generally be described as the cross-sectional shape of a wing, where the airfoil shape creates the aerodynamic force.
Various airfoil shapes exist in the prior art depending on the type of aerodynamic force desired.
Downforce can generally be described as a downward aerodynamic force created by a wing or airfoil. While the most traditionally understood implementation of a wing or airfoil is in an airplane to create lift (upward force), the same principle can be used to provide downward force. Vehicles commonly employ wings or spoilers for this purpose, generating downward vertical force to generate more grip on the road.
A solar panel, or photo-voltaic (PV) module, can generally be described as a device configured to convert sunlight into electricity. This is accomplished through a plurality of photo-voltaic cells, which use the photovoltaic effect to excite electrons within the solar panels to create a flow of electric current. The more direct the sunlight, the more efficient the solar panels can generate energy. As such, when the solar panel receives the sunlight at a perpendicular angle, this will generate the most electricity.
While wings are common in land vehicles to generate downforce, and while electric land vehicles which utilize electrical power to drive themselves are becoming more and more common, there is a continued need for a solar wing capable of providing downforce while also generating electricity through solar energy. Furthermore, there is a continued need for a solar wing which can articulate to provide dynamic downforce while also providing a more efficient conversion of solar energy into electricity. The present invention satisfies these needs.
The present invention will provide a system configured to move a solar wing in three dimensions to increase downforce and solar panel efficiency. This is accomplished through a solar wing, a drive mechanism, a rail mechanism, and a support mechanism. These components work in conjunction to provide a lightweight and compact system configured to move and rotate a solar wing to maximize downforce and increase solar panel efficiency.
These and other objectives of the present invention will become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiments. It is to be understood that the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.

The present invention comprises a solar wing 20, a drive mechanism 30, a rail mechanism 40, and a support mechanism 50. The drive mechanism 30 is positioned at the proximal end 23 of the solar wing 20 and is configured to move the solar wing 20 in a linear motion. The rail mechanism 40 is positioned between the proximal 23 and distal ends 24 of the solar wing 20 and is configured to move the solar ring 20 along a rail 42, converting the linear motion of the drive mechanism 30 into vertical and horizontal motion. The support mechanism 50 is positioned at the distal end 24 of the solar wing 20 and is configured to provide a pivot point for the solar wing 20 while it is being moved by the other mechanisms. These components work in conjunction to provide a lightweight and compact system configured to move and rotate a solar wing 20 to maximize downforce, increase solar panel efficiency, and improve cornering performance.
The solar wing 20 comprises a carbon fiber body having a proximal 23 and distal end 24. The solar wing 20 further comprises a multi junction solar inlay 21, or plurality of solar panels 21, configured to convert solar energy into electrical energy. The solar wing 20 further comprises a generally airfoil shape and has a curvature configured to convert drag forces into downward force. The solar wing 20 has three attachment points, a drive mechanism 30 at its proximal end 23, a support mechanism 50 at its distal end 24, and a rail mechanism 40 between the proximal 23 and distal ends 24. In an alternative embodiment, the solar wing 20 further comprises a plurality of ribbed support members 22 positioned between said solar panels 21 to provide structural support. In a further alternative embodiment, the solar wing 20 further comprises a clear covering for a smooth airfoil shape and for protecting the solar panels 21. In yet a further alternative embodiment, the solar wing 20 comprises an air vacuum between the clear covering and carbon fiber body to prevent damage by particulate and dust.
The drive mechanism 30 is positioned at the proximal end 23 of the solar wing 30 and is configured to move the solar wing 20 in a linear motion. The drive mechanism 30 comprises a motor 31, a drive rail 32, and a support member 33 fixedly attached to the solar wing 20. The motor 31 is configured to move the support member 33 along the drive rail 32. The drive rail 32 is configured to receive the support member 33 and to restrict its movement laterally. The support member 33 is configured to travel along the drive rail 32 and is fixedly attached to the solar wing 20.
The rail mechanism 40 comprises a cam 41, a rail 42, a shaft 43, a spring 44, and a rail support 45. The cam 41 is in a fixed position and is configured to provide outward motion to the shaft 43 as it travels along the cam 41. The rail 42 is also in a fixed position and is configured to provide upward motion to the shaft 43 as it travels within the rail 42. The shaft 43 is positioned through the rail 42 and adjacent to the cam 41, and is fixedly attached to the rail support device 45 and solar wing 20 such that any forces applied to it from the cam 41 or the rail 42 are also applied to the rail support device 45 and solar wing 220. The spring 44 is positioned about the shaft 43 between the cam 41 and the rail 42 and is configured to provide compression force between the cam 41 and rail 42 such that the shaft 43 is always positioned adjacent to the cam 41. The rail support device 45 is configured to receive the shaft 43 and guide it along the rail 42. The rail support device 45 further comprises a plurality of wheels to ensure the shaft 43 travels smoothly within the rail 42, and further comprises a means of fixedly attaching to the solar wing 20.
The cam 41 has a curved, generally convex shape and is configured to push the shaft 43 outward as the shaft 43 travels along the rail 42. More specifically, as the shaft 43 travels along the rail 42 and the surface of the cam 41, the shape of the cam 41 will force the shaft 43 to travel laterally, perpendicular to the surface of the cam 41. The spring 44 will provide the necessary outward compression force to ensure that the shaft 43 is in constant physical contact with the cam 41 during this motion and to prevent any jittering or vibration during travel.
The rail 42 has an elongated, curved shape with an aperture configured to receive the shaft 43. The rail 42 is further configured to restrict the movement of the shaft 43 between the rail 42 as it travels within said aperture and as it travels along the cam 41. As the cam 41 forces the shaft 43 to travel laterally, the rail 42 will ensure that the shaft 43 remains within a restricted area to ensure proper continuous motion. In a first position, or closed position, the drive mechanism 30 is retracted fully and the solar wing 20 is in a resting position. Here, the downforce generated by the solar wing 20 will be the lowest. In a second position, or open position, the drive mechanism 30 has driven the drive support member 33 at its furthest point on the drive rail 32, and as such, the shaft 43 will have traveled along the cam 41, causing the solar wing 30 to open vertically and laterally (outward). Here, the downforce generated by the solar wing 20 will be at its highest.
The support mechanism 50 comprises an elongated support beam 51 and a ball joint 52. The support mechanism 50 is positioned at the distal end 24 of the solar wing 20 and is configured to provide a pivot point for the solar wing 20 while it is being moved by the other mechanisms. The elongated support beam 51 is configured to provide structural support to the distal end 24 of the solar wing 20, while the ball joint 52 is configured to provide radial motion to the solar wing 20 as it moves pursuant to the lateral motion of the drive mechanism 30, the outward motion of the cam 41, and the upward motion of the rail 42.
The control mechanism 60 is configured to control the drive mechanism 30. More specifically, the control mechanism 60 is configured to produce lateral movement from the motor 31 to the support member 33 along the drive rail 32. This lateral movement will also generate upward and outward movement of the solar wing 20, depending on the desired wing position and wing angle. For example, if an increase in angle of the solar wing 20 is desired, the control mechanism 60 will activate the motor 31, causing the support member 33 to travel along the drive rail 32 until the desired solar wing 20 position and angle are produced.
In the preferred embodiment, the solar wing 20 is attached to a land vehicle and the control mechanism 60 is in electrical communication with a plurality of sensors 70. The plurality of sensors 70 further comprises velocity sensors, steering wheel angle sensors, GPS position sensors, directional sensors, pressure sensors, temperature sensors, collision sensors, fault sensors, or any other sensors which can be used to determine the properties of the vehicle and the surrounding environment. These sensors 70 may work alone or in conjunction to provide input to the control mechanism 60 to adjust the position and angle of the solar wing 20.
In this embodiment, the control mechanism 60 will process the input obtained from the vehicle's sensors 70, which includes constantly changing wing dynamics in real time, to modify the solar wing 20 position and angle relative to vehicle's axis. The control mechanism 60 is configured to optimize the output variables, wing position and wing angle, each differently depending on the driving conditions of the vehicle. Examples of output variables include increasing downforce, increasing turning force, reducing drag, or increasing solar power absorption.
In a first embodiment, when optimizing for increased turning speed, the control mechanism 60 is configured to optimize the solar wing 20 position and angle to optimize for maximum downforce. Here, the control mechanism is configured to receive vehicle velocity and steering angle from the vehicle. Using this input, the control mechanism 60 will adjust the position and angle of the solar wing 20 to maximize the downforce relative to these inputs. This will increase the grip the vehicle has on the road, increasing the speed at which the vehicle can make the turn.
In an alternative embodiment, the control mechanism 60 is configured to further optimize the solar wing 20 position and angle to optimize for downforce while in a turn by dynamically adjusting each solar wing 20 individually. Here, while the vehicle is cornering around a turn, and where the solar wings 20 are positioned on either end of the vehicle, the control mechanism 60 will receive vehicle velocity and steering angle input and adjust each solar wing 20 relative to the other such that the solar wing 20 closer to the turning corner is configured to open more than the opposing solar wing 20. This results in a force opposite to the direction of the turn, which will optimize the cornering performance while not increasing the experienced drag force.
In a further alternative embodiment, the control mechanism 60 is configured to optimize for maximum solar influx onto the multi junction solar inlay 21 in between the ribbed support members 22 along the solar wing 20. The control mechanism 60 receives velocity, time, longitude, and latitude input to ensure that the car is in a stationary position and to determine the general position of the sun relative to the position of the car. The control mechanism 60 will then modify the solar wing 20 position and angle such that the multi junction solar inlay will optimize solar absorption. More specifically, the control mechanism 60 will attempt to angle the solar inlay 21 such that it is perpendicular to the sun, as this is will produce the most energy. In an alternative embodiment, the control mechanism 60 will calculate the average angles of all solar panels and adjust the solar wing such that the highest overall energy absorption is achieved.
