Rear-view camera and light system for vehicle
A rear-view camera and light system for a vehicle having a rear-view camera, a back light, and a brake light and an attachment structure that attaches the system to a center hub of a spare tire at the back of the vehicle. The rear-view camera and light system includes a mounting base having a plate like shape and configured to attach to a mounting bracket provided on about a center of a back of a vehicle for mounting a spare tire, a mounting post having a cylindrical shape with a hollow therethrough and configured to attach to the mounting base at one end, and a camera/light unit having circular shape and configured to attach to another end of the mounting post.
1. A rear-view camera and light system for a vehicle, comprising:
a mounting base having a plate like shape and configured to attach to a mounting bracket provided on a back of a vehicle for mounting a spare tire;
a mounting post configured to attach to the mounting base at one end, and to pass through a center bore of the spare tire, which is a center hole in a wheel of the spare tire, wherein the mounting post is cylindrical shape having a hollow space therein; and
a camera/light unit configured to attach to another end of the mounting post, the camera/light unit including a rear-view camera, a back light, and a brake light;
wherein the camera/light unit is attached at a hub of the spare tire via the mounting base and the mounting post, and wherein:
the brake light is located at about a center of the camera/light unit and is extended in a horizontal direction;
the back light is provided at an upper location of the camera/light unit, and oriented to face diagonally downward; and
the rear-view camera is provided at a lower location of the camera/light unit, and oriented to face diagonally downward.
2. The rear-view camera and light system for a vehicle as defined in claim 1 , further comprising:
an electric cable for electrically connecting the camera/light unit with electric components provided inside of the vehicle, the electric cable being configured to run through the hollow space of the mounting post.
3. The rear-view camera and light system for a vehicle as defined in claim 2 , further comprising:
a slit formed on the mounting base to introduce the electric cable from the camera/light unit to the electric components in the inside of the vehicle.
4. The rear-view camera and light system for a vehicle as defined in claim 1 , further comprising:
a lug nut camera base provided between the another end of the mounting post and the camera/light unit;
wherein the lug nut camera base has a camera base bolt at its center so that the camera/light unit is connected to the lug nut camera base by the camera base bolt with use of a lug nut.
5. The rear-view camera and light system for a vehicle as defined in claim 4 , wherein:
the lug nut is a locking nut to prevent theft which requires a special adaptor between the nut and a wrench to remove from the camera base bolt.
6. The rear-view camera and light system for a vehicle as defined in claim 4 , further comprising:
a first face gear provided on the camera/light unit and a second face gear provided on the lug nut camera base;
wherein the first face gear includes a first set of teeth that meshes with a second set of teeth provided on the second face gear, thereby the light/camera unit is rotatably adjustable around a center axis when the camera/light unit is attached to another end of the mounting post.
7. The rear-view camera and light system for a vehicle as defined in claim 6 , wherein:
the first set of teeth of the first face gear includes 36 teeth and the second set of teeth of the second face gear includes 36 teeth.
8. The rear-view camera and light system for a vehicle as defined in claim 1 , wherein:
the rear-view camera at the lower location of the camera/light unit is separated from the back light by a predetermined distance, whereby reducing light interference of images.
9. The rear-view camera and light system for a vehicle as defined in claim 8 , wherein:
the predetermined distance between the rear-view camera and the back light is in a range between 40 mm and 180 mm.
10. The rear-view camera and light system for a vehicle as defined in claim 1 , wherein:
the rear-view camera at the lower location of the camera/light unit is separated from the break light by a predetermined distance, whereby reducing light interference of images.
11. The rear-view camera and light system for a vehicle as defined in claim 10 , wherein:
the predetermined distance between the rear-view camera and the break light is in a range between 20 mm and 140 mm.
12. The rear-view camera and light system for a vehicle as defined in claim 1 , further comprising:
a plurality of mounting posts with different lengths;
wherein the mounting post with an appropriate length is selected depending on difference in back spacing of a spare tire wheel with the mounting bracket, thereby maintaining the location of the camera/light unit regardless of types of spare tire wheel and depths of mounting bracket to capture an image of ground immediate to the back of the vehicle.
13. The rear-view camera and light system for a vehicle as defined in claim 1 , wherein:
the mounting post has a cylindrical shape with a hollow therethrough.
14. The rear-view camera and light system for a vehicle as defined in claim 1 , wherein:
the camera/light unit has a circular shape and is attached at a center of the hub of the spare tire.
