The present invention generally relates to side-view, rear-view and/or cross-view mirrors for large vehicles, such as school buses, transit buses and trucks. Specifically, the present invention relates to side-view, rear-view and/or cross-view mirrors containing a camera for use by a driver as an additional sight-aide.
One example of a side-view mirror example of the type that may be used for the present invention is described in U.S. Pat. No. 6,059,419, hereby incorporated by reference in its entirety. In the present invention, the side-view mirror advantageously incorporates a camera to aide a driver by providing additional information that may not be obtained by viewing an image in a side-view mirror alone. As one example, a side-view mirror is provided with a camera that provides an image to a display screen in view of the driver within the vehicle. The camera may advantageously be, for example, provided with night-vision or high sensitivity sensors to provide the driver with an image in poor lighting conditions. The camera may optionally be further provided with infrared sensors such that a driver would be able to discern heat signatures of individuals or animals within view of the camera. According to one optional embodiment, the driver may control the selection of the type of image provided by the camera, e.g., night-vision, infrared, standard, etc. Advantageously, the present invention allows a driver to turn and back up a large vehicle while able to see objects, individuals and/or animals in poor lighting conditions. In alternative optional embodiments, the camera is aided with additional lighting attached to the housing, integrated within the housing and/or attached to the side of the vehicle.
According to one embodiment, the camera may be connected to a monitor within the vehicle in a wired or a wireless manner. For example, the camera may be connected by USB, fiber optic, coaxial, component, Ethernet, HDMI, WiFi, Bluetooth, radio, etc. In some embodiments, the camera and/or monitor is wired to an existing power source associated with the vehicle. In other embodiments, dedicated additional power sources or shared power sources are provided for the monitor and/or camera unit located within the monitor and/or camera, within the vehicle engine compartment and/or in other areas of the vehicle. When the power source is located remote from the camera, wiring for the connection to the power source may optionally be disposed within the mirror pole and one or more support arms for connection to area within the vehicle.
Mounting hole 11 provides an opening for the mirror pole 20 to enter the shell housing 10. A grommet 22 is disposed in the mounting hole 11 and prevents moisture, dirt and the like from entering the shell housing 10 through the mounting hole 11. The mirror pole 20 comprises a first support arm 26 and a second support arm 28 each having a mounting hole 21 on its distal end. While
According to another embodiment, the invention is provided with a first mirror unit as described above and second mirror unit is replaced with a wide-angled camera to provide a field of view similar to the field of view of a convex mirror and/or other types of camera lenses. According to other embodiments of the present invention, more than two mirrors are provided, each mirror providing a different field of view. Advantageously, a camera may be provided in any or all of the mirrors for providing a driver with multiple fields of view on a monitor within the vehicle.
With reference to
The flat mirror 60 is disposed on a flat mounting plate 61 and secured at its edges by a long snap 62 and a short snap 63. Relative ease of installation of the flat mirror 60 onto the flat mounting plate 61 is achieved by first inserting one edge of flat mirror 60 under one of the long snap 62 and the short snap 63 and then pressing the other end of flat mirror 60 under the remaining snap to obtain secure engagement of the flat mirror 60 to the flat mounting plate 61. It is preferred that one edge of the flat mirror 60 is first placed under the long snap 62 and then the other end of flat mirror 60 is snapped under short snap 63.
The ease with which the flat mirror 60 is secured to, and removed from, the flat mounting plate 61 enables field replaceability and retrofitability of the flat mirror 60, for example, when the flat mirror 60 is accidentally broken. Alternative connection systems may optionally be used to connect flat mirror 60 from flat mounting plate 61, for example, using an adhesive or other standard means for securing mirror 60 to the mounting plate 61. In addition, mirror 60 need not be flat, and other types of mirror lenses may be used, such as dome type mirror lenses.
Optional vibration tabs 64 extend somewhat above the plane of the flat mounting plate 61 and are elastically biased to engage the rear surface of the flat mirror 60 when the mirror is engaged under the long snap 62 and the short snap 63. The force exerted by the vibration tabs 64 to the rear surface of the flat mirror 60 prevents vibrations in the flat mirror 60 when the vehicle is in motion or when vibrations are transmitted to the first mirror unit 16 from other sources such as, for example, from the engine of the vehicle.
With reference to
The solenoid 76 is positioned such that the core 78 contacts the inside surface of the shell housing 10 when the solenoid is not energized and the spring forces the core 78 into its outward position. Therefore, when the solenoid is not energized, vibrations of the flat mounting plate 61 with respect to the shell housing 10 are damped.
However, when it is desired that the position of the first mirror unit 16 be changed via the motors of the swivel mechanism 66, the solenoid 76 is concurrently energized with the motors (via, for example, the motor control switch) such that the core 78 is drawn inwardly and away from the inside surface of the shell housing 10 thus enabling free movement of the flat plate 61 with respect to the swivel mechanism 66. Further, when the first mirror unit 16 has reached the desired position and the motors of the swivel mechanism 66 are deactivated, the solenoid 76 is also deactivated and the core 78 returns to its resting position against the inside surface of the shell housing 10.
With reference to
In various embodiments a power supply is provided to power the motors in each of the first and second mirror units as well as a camera. In other embodiments, a separate power supply is provided for each component component or existing power supplies on the vehicle may optionally be used.
The shell housing 10, the flat mounting plate 61, the cup 65, the swivel mechanism 66, the connecting plate 73, the convex mounting plate 81, the cup 85, the swivel mechanism 86 and the connecting plate 93 may be manufactured from suitable plastics, metals, composite materials or the like. It is preferred that the above-listed elements be manufactured from suitable plastics. The mirror pole 20 and the hinge member 30 may also be manufactured from suitable plastics, metals, composite materials or the like; however, it is preferred that these elements be manufactured from suitable metals. As described above, it is most preferred that mirror pole 20 and the first and second support arms 26, 28 be manufactured from steel and the core material 23 be manufactured from aluminum.
