DETAILED DESCRIPTION
Reference is now made to FIG. 1 illustrating a vehicle V equipped with a hidden camera system 10 which is concealed behind the cover 12 which, in the illustrated embodiment, is formed by the manufacturer emblem. As illustrated in FIGS. 2 and 3, the hidden camera system 10 includes a housing or enclosure 14 that holds a camera 16, a drive motor 18 and associated gear transmission 20, and a linkage 22 connecting the drive motor and gear transmission to the cover 12 and the camera 16. A gasket 17 is provided around the first or front opening 19 of the housing 14 and seals the front of the housing when the cover 12 is closed.
As illustrated, the linkage 22 includes a crank arm 24, a first link 26, a second link 28, a cover support bracket 30 on which the cover 12 is mounted, and a camera mounting bracket 32. More specifically, the crank arm 24 is connected to the gear transmission 20 by a rotating driveshaft 34. The opposite end of the crank arm 24 is pivotally connected to the first link 26 by the pivot pin 36. The second end of the first link 26 is connected to the second link 28 by the pivot pin 38. The first end of the second link 28 is connected to the cover support bracket 30 by a pivot pin 40. The second end of the second link 28 is connected to the camera mounting bracket 32 by a cam or roller 42 that is received and moves in a track 43 provided on the camera mounting bracket.
As should be further appreciated, the second link 28 is pivotally mounted at a first point to the housing 14 by a pivot pin 45 received in a boss 44 (see also FIG. 7). The pivot pin 38 connecting the first and second links 26, 28 is provided at a second point on the link 28 between the first point and the second end. In the illustrated embodiment, the second link 28 is substantially c-shaped.
The camera mounting bracket 32 includes flanges 46 and other related structures to engage the housing 48 of the camera 16 and securely hold the camera in position. The camera mounting bracket 32 is pivotally connected to the housing 14 by means of a first pivoting support arm 50. More specifically, the support arm 50 is pivotally supported on the housing 14 by means of the boss 52. The cover support bracket 30 (and, therefore, the cover 12 supported thereon) is pivotally mounted to the housing 14 by means of a second pivoting support arm 54. More specifically, the second support arm 54 is pivotally mounted to the housing 14 on the boss 56.
FIGS. 2 and 3 illustrate the hidden camera system 10 with the camera 16 in the fully retracted position and the camera hidden from view by the cover (deleted from figure for clarity). When activated, the camera 16 is displaced to a fully deployed position illustrated in FIGS. 4 and 5. More specifically, the drive motor 18 operates through the gear transmission 20 and the driveshaft 34 to turn the crank arm 24 in the direction of action arrow A. This causes the first link 26 to translate in the direction of action arrow B so as to pivot the second link 28 about the boss 44 in the direction of action arrow C. This simultaneously causes the cover 12 to pivot open about the boss 56 and the camera 16 to pivotally deploy about the boss 52. An abutment 58, projecting from the side of the camera mounting bracket 32 engages a stop 60 on the housing 14 when the camera 16 and cover 12 are both in the fully deployed position. Here it should be appreciated that a biasing element, in the form of a torsion spring 62 received around the boss 52, biases the camera 16 toward the fully deployed position. See FIG. 8. This ensures that the camera 16 is repeatedly fully deployed into the same position during each deployment. More specifically, the torsion spring 62 has a first end 64 secured in a socket 66 to the housing 14 and a second end 68 engaging the camera mounting bracket 32.
When it is desired to retract the camera 16, the drive motor 18 is driven in the opposite direction. This drives the crank arm 24 in the direction opposite to action arrow A which in turn causes the drive link 26 to translate in a direction opposite to action arrow B. As a result, the second link 28 pivots in a direction opposite to action arrow C causing the camera 16 to be retracted while the cover 12 is closed. When the camera 16 is fully retracted and the cover 12 is fully closed, the abutment 58 engages a second stop 70 formed on the housing 14. See FIG. 7.
As illustrated in FIG. 9, the hidden camera system 10 may also include a nozzle jet 71 for cleaning the lens or cover window 72 of the camera 16. More specifically, during each cleaning cycle cleaning fluid is fed by a pump (not shown) to the nozzle jet 71 through the delivery line 74 and is expelled in a washing stream 76 across the lens or cover window 72 Such a cleaning cycle may be initiated from inside the vehicle each time the vehicle operator engages the wiper washer to clean the windshield.
As illustrated in FIGS. 2-5 and 7, the housing or enclosure 14 includes a second or rear opening 80 opposite the first or front opening 19. As illustrated in FIGS. 10 and 11, a flexible seal 82 closes and seals the opening 80 to prevent dirt, debris and contaminants from entering the housing 14 from the rear side. This helps to maintain the drive motor 18, transmission 20, linkage 22 and camera 16 in peak operating condition.
In addition, it should be appreciated that the flexible seal 82 provides additional pedestrian protection when compared to a hard or rigid structural element. More specifically, the flexible nature of the seal 82 will not convey load from the forward portion of the housing 14 in the event of an impact event should the seal contact fixed members to the rear of the housing. As such, an enclosure or housing 14 with a flexible rear wall or seal 82 provides a distinct safety benefit.
It should be appreciated that the flexible wall or seal 82 may take a number of different forms. In the embodiment illustrated in FIGS. 10 and 10a, the seal 82 comprises a pleated diaphragm of elastomeric or resilient material. In the FIG. 11 embodiment, the flexible wall or seal 82 includes one or more openings 84 to route control and/or power lines 86. In any embodiment, the seal 82 may include a cavity 88 open toward the interior of the housing 14.
The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the camera system 10 to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
