BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates generally to a vehicle sunshade and more particularly to an automated vehicle sunshade that is formed of a photovoltaic material.
2. State of the Art
Vehicles are driven to various places that people need to go and are often parked in a parking lot that is open and exposed to the elements of nature. The weather conditions often affect the vehicles parked in these types of parking lots. One type of weather condition that is of particular concern is a sunny, hot day. With the temperature being hot and a vehicle exposed to the sun for extended periods of time, the rays of the sun enter the vehicle through the windows and the vehicle becomes hotter than the ambient temperature outside of the vehicle. This often causes great discomfort for people who must then enter the vehicle and in some instances can even cause harm such as burning of the person within the car.
This concern is greater in regional locations where the temperature is consistently hot for a substantial period of time. In these types of locations, people often tint their vehicle windows and/or use conventional sunshades in an attempt to block or deflect at least a portion of the sun rays entering the vehicle. While shade serves to provide a much cooler vehicle, the conventional sunshades have several limitations.
Conventional sunshades are typically made for use on the windshield. This allows the owner of the vehicle to block a portion of the sun from entering the car, but cannot block the sun from entering all of the windows of the vehicle. Often, the owner will park in such a direction that most of the sun will be blocked during the time the vehicle is parked in that particular location.
Further, other typical sunshades may be used to block the sun from portions of other windows by use of sunshades with suction cups to retain them on the window. These often fall and do not cover the entire window, thereby exposing the inside of the vehicle to the sun. Additionally, as the type of vehicle changes, the need for different types of sunshades is required to account for the varying types of windows on the vehicle.
Conventional sunshades are limited to only providing shade to the inner portion of the vehicle and do not protect the outer vehicle parts from exposure to the sun. For example, and not as a limitation, vehicle doors and door handles are often formed of a type of metal. The metal exposed to the sun often heats to a degree that it is hot to the touch causing difficulty to the person attempting to open the hot door who must grasp the hot handle. Further still, the vehicle engine is hot and starting can result in inefficient starting and consumption of greater fuel.
Due to the limitations of conventional sunshades, owners often use other means to block the sun from certain vehicle parts. For example, and without limitation, a steering wheel cover is used to protect the steering wheel and provide a material that does not heat as easily, a towel or other cover is used to cover parts such as a seat belt buckle, a car seat and even leather or vinyl seats.
Additionally, while the sun is often a problem in warmer climates, colder climates have other needs with their vehicle windows. For example, in climates were there is snow, conventional methods of removing snow from a window of a vehicle include the use of a brush to brush the windows free from snow. Additionally, in cold climates, ice forms on the windshield and other vehicle windows. An ice scrapper is often utilized to free the window from ice.
Accordingly, there is a need in the field of vehicle sunshades for an improved vehicle sunshade.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
As discussed above, embodiments of the present invention relate to an automated vehicle sunshade that provides shade to all windows of a vehicle independent of the sun location and further provides shade to portions of the vehicle exterior.
As shown in FIGS. 1A-1C and 2A-2C, particular embodiments of the present invention include an automated vehicle sunshade 10. The sunshade 10 comprises a compartment 12, retractable extendable rods 14, support wires 16, guide wires 18 and 20, a shade 22 and a drive device 30. The retractable extendable rods 14 comprise a first end 13 and a second end 15 and may be telescopically extendable and retractable between an extended and a retracted position. The rods 14 may further have a predetermined curvature, such that when in the extended position, the second end 15 of the rods 14 extends below the first end 13 of the rods 14. Each retractable extendable rod 14 may be coupled at one end to the drive device 30 and at the other end to an end of the rod cable 16. The other end of the rod cable 16 may be coupled to the drive device 30 below the rod 14. The rod cable 16 may provide support for the rod 14 when the rod 14 is in the extended position. When the rod 14 is extended, the rod cable 16 is free to extend with the rod 14 into the extended position. When the rod 14 is retracted, the rod cable 16 is also refracted.
It will be understood by those of ordinary skill in the art, that the curvature of the rods 14 is not limited in the amount of curvature. So long as the rods 14 may be refracted within the compartment 12, the curvature of the rods 14 is proper. Further still, it will be understood that the present invention is not limited to rods, but may use other types of devices to support the shade, such as, but not limited to hinged members such as metal, fiberglass and the like in a zigzag configuration. Additionally, the number of rods 14 utilized may be any number such as 2, 3, 4, 5, 6 or more.
The shade 22 may be coupled to the retractable extendable rods 14. For the exemplary purposes of this disclosure and not as a limitation, the shade 22 may be a frusto-pyramidal shape. The corners 24 of the shade 22 may be coupled to the second ends 15 of the retractable extendable rods 14. A center portion 26 of the shade 22 may be coupled to the compartment 12. The guide wires 18 may be transverse to the guide wires 20, wherein the guide wires 18 and 20 are coupled on one end to edges of the shade 22 extending between each of the second ends 15 of the rods 14 and coupled to the drive device 30 on another end. The guide wires 18 and 20 may be free to extend when the rods 14 are moved into the extended position. The guide wires 18 and 20 provide support and guidance for properly retracting the shade 22 within the compartment 12, wherein the drive device 30 retracts the guide wires 18 and 20, thereby retracting and folding in the shade 22. The drive device 30 may have gear ratios driving the retracting of each of the guide wires 18 and 20, the support wires 16 and the rods 14 wherein the retraction of each of the guide wires 18 and 20, the support wires 16 and the rods 14 occur substantially contemporaneously.
The shade 22 may be formed of a flexible, durable material that may easily be folded to a size that fits within the compartment 12. Further, particular embodiments of the present invention may include a shade that has apertures extending through portions of the shade to allow air and wind to pass through, thereby allowing the shade 22 to remain open in a certain amount of wind without causing damage to the sunshade 10.
Referring further to the drawings, FIG. 3 depicts a portion of an automated vehicle sunshade 10 in an extended position according to particular embodiments of the present invention. In operation and with reference to FIG. 3, the automated sunshade 10 may be opened into an extended position. The compartment 12 may further comprise moveable flap portions 11. The flap portions 11 are moveable between an opened and a closed position wherein the opened position allows the shade to be extended and the closed position retains all the components of the sunshade 10 within the compartment 12. The drive device 30, covered by drive cover 31, may be activated, wherein the drive device extends the retractable extendable rods 14. As the rods 14 begin to extend, the rods 14 may engage the flap portions 11 and move the flaps 11 into the opened position. The support wires 16 and the guide wires 18 and 20 are not inhibited from extending with the rods 14. As the rods 14 extend, the shade 22 (as shown in FIG. 1) pulls the guide wires 18 and 20 into the extended position. Once the rods 14 are fully extended, the drive device 30 is automatically deactivated and the shade remains in the extended position. When in the extended position, the shade 22 may provide shade for not only all of the windows, but may also provide shade for a portion of the vehicle, including, but not limited to potions of the door, door handles, a portion of the hood, a portion of the trunk and the roof. This enables a user of the sunshade 10 to protect himself or herself from some injuries from touching hot metal when opening the vehicle door, and further provides shade to the hood and roof of the car to further limit the amount of heat transfer into the vehicle.
When shade is no longer desired over the vehicle, the sunshade 10 may be refracted. The drive device 30 may then be activated again. The drive device 30 now begins to retract the rods 14, the support wires 16 and the guide wires 18 and 20 substantially contemporaneously. The retraction of the guide wires 18 and 20 along with the rods 14 may provide proper folding of the shade such that the shade is folded into a size that fits within the compartment 12. Once the rods 14, support wires 16 and the guide wires 18 and 20 are fully retracted, the drive device 30 further retracts compartment cables 28, wherein the compartment cables 28 are coupled to the flaps 11. As the drive device 30 retracts the compartment cables 28, the flaps 11 are moved into the closed position and retain the other components of the sunshade 10 within the compartment 12. Once the flaps 11 are fully closed, the drive device 30 may automatically deactivate.
In other particular embodiments, the flaps 11 of the compartment 12 may be opened and closed automatically, such as by use of an actuator. The actuator may be, but is not limited to, hydraulic cylinders, mechanically driven linkages, slide mechanisms, and the like, so long as the flaps 11 may be automatically opened and closed.
Referring further to the drawings, FIG. 4 depicts a particular embodiment of a drive device 30 in accordance to the present invention. The drive device 30 may comprise gears 32, 33, 34 and 35, motor 36 and rod cables 38. In operation, the motor 36 may be activated, wherein the activation of the motor 36 actuates the rotation of the gears 32, 33, 34 and 35. The gears 32, 33, 34 and 35 may be coupled to the rod cables 38 as well as the support wires 16 and the guide wires 18 and 20. The rod cables 38 extend and retract the rods 14 by mechanically coupling the rods to the drive device 30. The gears 32, 33, 34 and 35 have ratios that provide substantially contemporaneous extension and refraction of the rods 14, the support wires 16 and the guide wires 18 and 20. The motor 36 may be an electrical motor and has a power source and a controller. The controller of the drive device 30 provides the proper information as to when to activate and deactivate the motor 36. Additionally, elastic members may be used to assist in retracting the sunshade within the compartment.
It will be understood by those of ordinary skill in the art that while particular gears are shown, the orientation, placement and gear ratios may be any type of orientation, placement and gear ratio, so long as the shade is foldable within the compartment 12 and contained within the compartment 12.

When the sunshade 250 is activated, the cover 251 extends in a direction away from the base 256. The cover 251 may further have two sets of opposing flaps 252 and 254. The flaps 252 and 254 may rotate so as to not inhibit the extension of the shade 260 from the base 256. The operation of other components of the vehicle sunshade 250 is the same as the operation of other embodiments of the present invention.

In one embodiment of the invention shown in FIG. 25, automated vehicle sunshade 22 is formed of photovoltaic material. A photovoltaic material converts light rays 322 into electrical charge, as shown in FIG. 26. Light rays 322 can be sunlight, but are no limited in this aspect. FIG. 26 shows photovoltaic material 320. Photovoltaic material 320 generates electrical charge 321, or current 321, when sunlight is incident on photovoltaic material 320. In this embodiment electrical charge 321 is harvested and stored in battery 312. Automated vehicle sunshade 22 is meant to block sunlight. Converting the sunlight incident on automated vehicle sunshade 22 into electrical charge 321 and storing electrical charge 321 is one way to put the incident sunlight to good use. Automated vehicle sunshade 22 consists in this embodiment of one or more than one panel of photovoltaic material 320. A panel of photovoltaic material 320 is also known as a solar cell, a solar collector, or a photovoltaic panel.
FIG. 25 shows automated vehicle sunshade 22 electrically coupled to charge controller 310 and battery 312. In this embodiment the flexible material that automated sunshade 22 is formed of is photovoltaic material 320. In some embodiments one or more than one panels of photovoltaic material 320 are attached to the flexible material that forms automated vehicle sunshade 22. In the embodiment shown in FIG. 25 the photovoltaic material is silicon, which can be in the form of crystalline silicon, polycrystalline silicon, or amorphous silicon. In some embodiments the photovoltaic material is cadmium telluride. In some embodiments the photovoltaic material is a solar ink or a solar dye or a conductive plastic. The photovoltaic material in automated sunshade 22 can be any material that converts optical radiation into electrical charge.
Sunlight incident on automated vehicle sunshade 22 is converted into electrical charge 321 in response to the light rays 322 hitting photovoltaic material 320 comprised in automated vehicle sunshade 22. Electrical charge 321 is collected and regulated by charge controller 310. A charge controller is also known in the art as a charge regulator. Charge controller 310 collects electrical charge 321, or current 321, created by photovoltaic material 320 and converts it into voltage or current. The voltage created by the automated vehicle sunshade 22 in this embodiment is between 6 and 40 volts, but the invention is not limited to these voltage levels. Automated vehicle sunshade 22 and charge controller 310 can convert electrical charge 321 into any voltage or current level. This voltage can vary in other embodiments depending on how many individual panels of photovoltaic material 320 are used and how they are electrically connected. Photovoltaic panels used in the invention can be electrically connected in parallel to increase current or in series to increase voltage or in series/parallel to increase both current and voltage. In this embodiment the 6 to 40 volts created is regulated by charge controller 310 and sent to battery 312 for storage. Battery 312 can be a car battery. Battery 312 can be a battery used solely for powering automated vehicle sunshade 22. Battery 312 can be a battery that is used to collect charge 321 from automated vehicle sunshade 22 and when full, is removed and replaced with a new battery to be charged. Battery 312 can be any battery used for any purpose. In some embodiments the charge 321 collected from automated vehicle sunshade 22 is stored in a different form of energy storage device, such as a fuel cell.
In some embodiments battery 312 that is used to store electrical charge 321 generated by automated vehicle sunshade 22 is the battery that powers the vehicle that automated vehicle sunshade 22 is mounted to. In this embodiment automated vehicle sunshade 22 will recharge battery 312 while the vehicle is parked. In some embodiments the vehicle is an electric vehicle. Automated vehicle sunshade 22 can be used to re-charge the vehicle's battery 312 when an electrical outlet is not available.
Electrical charge 321 generated by automated vehicle sunshade 22, collected by charge controller 310, and stored in battery 312 can be used for many purposes. In some embodiments battery 312 can power auxiliary devices 314. FIG. 27 shows auxiliary device 314 coupled to battery 312 such that battery 312 provides power for auxiliary device 314. Auxiliary device 314 can be many different types of devices. In some embodiments auxiliary device 314 is a block heater. Block heaters are used in cold climates to keep engine blocks warm when the temperatures are so low that starting an engine becomes difficult to impossible because of the low temperature of both the engine and the battery. The problem is that powering the block heater while the vehicle is off requires additional energy from the already-stressed battery unless an external power source is available. In this embodiment the electrical charge generated by automated vehicle sunshade 22 can be used to power the block heater. The heated block will require less power from the battery when started, and the block heater has not used battery resources to keep the block warm, but has instead used power generated by automated vehicle sunshade 22. Automated vehicle sunshade will be deployed and generated electrical charge while the vehicle is parked, which is when the block heater is needed.
In some embodiments the electrical charge generated by automated vehicle sunshade 22 can be used to power portable devices such as cellphones, laptops, or GPS units. In a particular embodiment automated vehicle sunshade 22 includes a remote cellphone antenna. In this embodiment the electrical charge generated by automated vehicle sunshade 22 can be used to boost the sending and receiving power of the cellphone, increasing the service coverage area of the phone.
It is to be understood that numerous embodiments of automated vehicle sunshade 22 formed of a photovoltaic material are possible. Electrical components and interconnects different from that shown in FIG. 25, FIG. 26, and FIG. 27 are envisioned as part of the invention. Further, while some embodiments are shown with the vehicle sunshade 22 being gathered when in the retracted position, it will be understood that some embodiments may include rolling the material on a spring loaded roller, wherein the drive device 30 operates to roll and unroll the sunshade 22 in a similar manner as other spring-loaded rolling apparatuses, such as, but not limited to, an automated awning.
Further, a method of using a vehicle sunshade 22 may comprise the steps of coupling a flexible shade to a vehicle, wherein the flexible shade comprises photovoltaic material; moving the flexible shade from a retracted position to an extended position, wherein sunlight hits the photovoltaic material; creating an electrical charge in response to the sunlight hitting the photovoltaic material; collecting and regulating the electrical charge in response to operation of a charge controller operatively connected with the flexible shade; and storing the electrical charge in a battery operatively connected to the charge controller. Further, the method may comprise the step of providing power to an auxiliary device operatively coupled to the battery.
It will be understood that various ways of mounting an automated vehicle sunshade may be utilized without departing from the scope of this disclosure. For example, and without limitation, the mounting may include devices such as, magnets, straps, clamps, tie downs, clips, fasteners, bolts, adhesives, hook-and-loop fasteners, and any combinations thereof. The sunshade may be mounted on parts of a vehicle including, but not limited to a roof and a roof rack. Further, the sunshade may be permanently mounted on the vehicle, removably mounted on the vehicle or integral to the vehicle. In instances where the sunshade is integral to the vehicle, the compartment may be mechanically extended from the roof of the vehicle before activating the drive device.
For example, an integral vehicle sunshade may be provided as a vehicle upgrade, similar to a sunroof. The sunshade may not be readily distinguishable as a sunshade and provides a streamline aesthetic appearance.
Particular embodiments of the present invention may include an automated sunshade that is provided in various colors, shades, and surface treatments, so as to compliment the aesthetic qualities of the vehicle the sunshade is mounted to. Additionally, the shade portion of the sunshade may be of a complimentary color and/or may be of a highly reflective material and color.
It will be understood by those of ordinary skill in the art that while the present invention includes an automated vehicle sunshade, the sunshade may be manually operated. For example, if there is a type of malfunction of the motor, the power source and/or the like, the sunshade may still be retractable and extendable without a power source. It will also be understood that the automated vehicle shade may be utilized to shade areas around the vehicle depending on the placement of the sunshade on the vehicle. This enables shade to be provided near the vehicle for uses, such as, but not limited to, tailgate parties, road side concessions, parade viewing and the like. Additionally, written indicia may be placed on the shade material, such as advertisements, team sports, custom graphics and the like.
It will be understood that particular embodiments of the present invention may be used in other types of weather conditions, such as, but not limited to snow and other cold weather. For example, the automated vehicle sunshade may be used to shield the windows of a vehicle from retaining snow on the windows, thereby requiring no need for brushing of the snow away from the windows with a snow brush. Additionally, cold weather is often accompanied with ice formation on windows and often in door locks. Embodiments of the present invention may be used to shield the car, similar to a covering over a parking spot and prevent ice from forming on the windows and the within the key lock, thereby requiring no scraping of ice with an ice scraper nor requiring the deicing of the lock. It will be understood that the shade may be utilized to warm the vehicle, including the windows to melt ice.
