1. Field of the Invention
This invention relates to a visual watching device for an automobile, particularly to one for detecting the dead angle caused by a front post and a rear post of an automobile in order to keep the automobile safe in running.
2. Description of the Prior Art
Nowadays automobiles are indispensable tools in our daily life, and their accessories are quite a lot, especially for keeping them safe in running, for example, various radar or visual systems for backing cars. And the radar or visual systems generally includes a sensor fixed on the rear bumper for detecting the traffic condition behind the car for helping a driver to watch the road condition hidden by the dead angle impossible to be seen by the rearview mirror.
However, in using the rearview mirror, the front posts at the two sides are an obstacle for viewing functioning as a dead angle for a driver, making up a potential risk in running of an automobile. So a driver may lose the proper opportunity for stepping on the brake in time. Moreover, the dead angle by the rear post always becomes a great trouble for backing an automobile. Those dead angle caused by the front and the rear posts is almost impossible to be get rid of by means of conventional radar or observing system and only compensated by alarming sound.
This invention has been devised to offer a visual watching device for an automobile for detecting the dead angle caused by the front posts and the rear posts of an automobile. The device includes a camera respectively installed on the front and the rear posts and facing the exterior of the automobile, a thin display respectively fixed in the front and the rear posts, connected with the cameras electrically and facing the driver, and a power source supplying the cameras and the displays with electricity. Then the traffic conditions hidden by the front and the rear posts can be picked up by the cameras and shown on the displays for the driver to watch for taking necessary measures, to avoid accidents and keep safe his/her automobile and persons on it in addition to passersby and other automobiles.
This invention will be better understood by referring to the accompanying drawings, wherein:
A preferred embodiment of a visual watching system 1 for an automobile for detecting the dead angle caused by the front post in the present invention, as shown in
The cameras 10 are respectively deposited on two front posts and two rear posts of an automobile, with its lens 11 facing the exterior of the automobile. Then a user adjusts the proper angles of the cameras 10 and multiple of the lens 11, letting the road condition and the scene around the road completely picked up by the lens 11 and transmitted to the displays for showing out.
The displays 20 are very thin, with its width being almost the same as that of the front and the rear posts 2 and 3, and with its length being almost the same as that of the front and the rear post 2 and 3. The displays 20 are respectively deposited in the front and the rear post 2 and 3 properly so that the driver can look at them just straightly on the front sides or indirectly through the rearview mirror.
The signal wires 30 are respectively connected between each camera 10 and each relative display 20, so the image seen through the lens 11 may be completely and clearly shown on the screen of the displays 20.
The power source 40 is arranged in an automobile properly, and it can be a battery of an automobile, connected with each camera 10 and each display 20 by means of power wires 41 for supplying electricity.
In using, a driver can directly look at the displays 20 on the front posts 2, for viewing the scene and the traffic condition on the road it runs on, and the scene is the dead angle that could otherwise not be seen, and the driver can easily see it on the displays 20, as shown in
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claimed are intended to cover all such modifications that may fall within the spirit and scope of the invention.
