DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, a roof rack assembly is generally shown at 10 for allowing articles to be stored and transported along a roof 12 of a motor vehicle, generally indicated at 14. The roof rack assembly 10 includes a front frame member 16, a rear frame member 18, and side frame members 20, 22. Each of the frame members 16, 18, 20, 22 includes an inboard surface 24 and an outboard surface 26.
Various electronic components, including a radio frequency receiver module 28, a camera 30, and a radar sensor 32, are accommodated within the frame members 16, 18, 20, 22 of the roof rack assembly 10. It will be appreciated that the radio frequency receiver module 28, the camera 30, and the radar sensor 32 may be positioned along any of the frame members 16, 18, 20, 22. It will be further appreciated that each frame member 16, 18, 20, 22 can include more than one radio frequency module 28, more than one camera 30, and/or more than one radar sensor 32.
The frame members 16, 18, 20, 22 are formed from a thermoset or thermoplastic material and may be manufactured by injection or compression molding. In addition, the front frame member 16, the rear frame member 18, and the side frame members 20, 22 may be formed as a molded integral component.
A plurality of cross members 34 extend between the side frame members 20, 22 to assist the roof rack assembly 10 in retaining articles along the roof 12. The motor vehicle 14 includes an exterior rearview mirror 36 extending out from a side 38 to provide a motor vehicle operator with a view alongside and to the rear of the motor vehicle 14.
Referring to FIGS. 2 through 5, the front frame member 16 includes a lower panel 40, which is secured to the roof 12, and a body structure 42 secured to the lower panel 40. A sealing member 44, including but not limited to, an elastomeric gasket, extends between the lower panel 40 and the roof 12 to prevent the roof rack assembly 10 from scratching the roof 12. Although the lower panel 40 and the body structure 42 are shown with respect to the front frame member 16, it will be appreciated that the rear frame member 18 and the side frame members 20, 22 each include the lower panel 40 and the body structure 42.
Referring to FIGS. 2 and 4, the radio frequency receiver module 28 is seated within a housing 46 formed in the body structure 42 of front frame member 16. The radio frequency receiver module 28 receives signals from outside the motor vehicle 14, and may be utilized for cellular phones, wireless internet systems, satellite radio, global positioning systems, and guidance systems. Various housing 46 may be formed along the outboard surface 26 of each of the frame members 16, 18, 20, 22, as shown in FIGS. 4, 5, and 8.
Referring to FIGS. 2 and 4 5, the camera 30 is seated within rearwardly extending end segments 48 of the body structure 42 of front frame member 16. A camera retainer 50 is provided to hold the camera 30 within each of the end segments 48. A wire harness 52 connects each camera 30 and the radio frequency receiver module 28 to a power source (not shown).
The camera 30 is oriented within the front frame member 16 to create a digitized signal of a space alongside the motor vehicle 14. Referring to FIG. 6, the exterior rearview mirror 36 typically allows the motor vehicle operator to view the space alongside the motor vehicle 14. There are, however, blind spots along each side 38 that prevent the exterior rearview mirror 36 from showing a complete view along each side 38 of the motor vehicle 14. The camera 30 completes the view along one side 38 of the motor vehicle 14 and eliminates the blind spots.
The digitized signal created by the camera 30 is sent, via an output terminal 54, to a monitor 56 within a passenger compartment 58 of the motor vehicle 14. The monitor 56 may be an interior LED, a rearview interior mirror, or a display device devoted exclusively to the camera 30. Thus, the motor vehicle operator is able to view the blind spot along each side 38 of the motor vehicle 14 by viewing the monitor 56.
Referring to FIGS. 7 and 8, the camera 30 is positioned along the rear frame member 18. While the camera 30 may be positioned to face outwardly at various angles, the camera in FIGS. 7 and 8 faces downwardly towards the ground in order to eliminate a blind spot immediately behind the motor vehicle 14.
Furthermore, in a preferred embodiment, the camera 30 of the rear frame member 18 is designed to operate when the motor vehicle 14 is traveling in a reverse direction. Referring back to FIG. 6, the camera 30 includes a power switch 60 for turning the camera 30 on or off. The power switch 60 is operably connected to a reverse sensor 62 designed to identify when a transmission 64 of the motor vehicle 14 is in reverse. When the transmission 64 is shifted into reverse, the reverse sensor 62 sends a reverse signal to the power switch 60 to turn the camera 30 on. And when the transmission 64 is shifted out of reverse, the reverse signal is stopped and the power switch 60 turns the camera 30 off.
After the camera 30 is turned on, the camera 30 creates the digitized signal of a rear space behind the motor vehicle 14. The digitized signal is sent, via an output terminal 66, to the monitor 56. Thus, as the motor vehicle 14 travels in the reverse direction, the motor vehicle operator is able to view the blind spot behind the motor vehicle 14 by viewing the monitor 56.
Moreover, it is contemplated that the camera 30 may be activated even before shifting the transmission 64 into reverse to allow the motor vehicle operator additional time to survey the space behind the motor vehicle 14. It is also contemplated that the camera 30 may remain on at all times.
Referring to FIGS. 7 and 9, more than one radar sensor 32 is shown positioned along the rear frame member 18 on either side of a center high mounted stop lamp 68. The radar sensors 32 detect objects behind the motor vehicle 14 as part of a drive-by wire system or a similar computer-mediated driving system, as known to those skilled in the art.
A solar panel 70 may be secured to the outboard surface 26 of each of the frame members 16, 18, 20, 22. The solar panel 70 receives solar energy and converts the solar energy into an electric current to provide power to various systems or components of the motor vehicle 14. Referring to FIGS. 2 and 5, the solar panel 70 is secured to the outboard surface 26 of the front frame member 16. Referring to FIGS. 7 and 10, the solar panel 70 is shown secured to the outboard surface 26 of the rear frame member 18.
The solar panel 70 extends through a similar plane as the outboard surface 26 of the front 16 and rear 18 frame members. To optimize solar panel 70 performance, the plane through which the front 16 and rear 18 frame members extends is curved, and the solar panel 70 extends through the curved plane so that the solar panel 70 is tilted relative to the horizontal plane of the ground.
The invention has been described in an illustrative manner, and it is to be understood that the terminology, which has been used, is intended to be in the nature of words of description rather than of limitation. Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced other than as specifically described.
