Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-3, a large field angle fixed focus lens 1 includes a lens 1 for collecting and transmitting light, and a base for fixing the lens 1, the lens 1 is further provided with a wide-angle lens 2, the wide-angle lens 2 is fixedly disposed at the front end of the lens 1, the base includes a CCD chip 6, a frame 5 and a transmission line 7, and the lens 1 is movably connected with the base. The inner side wall of the frame 5 is provided with an internal thread 3, and the outer side wall of the lens 1 is provided with an external thread 4 corresponding to the internal thread 3. The lens 1 is connected with the base in a rotating mode through an internal thread 3 and an external thread 4. The focal length of the lens 1 is 20 mm to 13 mm. The CCD chip 6 is fixedly arranged on the inner side surface of the bottom of the frame body 5, and the transmission line 7 is electrically connected with the CCD chip 6.

In summary, the working principle is as follows: the focal length in the lens 1 is shortened, and because the wide-angle lens 1 has a short focal length and a large visual angle, a scene with a large area can be shot in a short shooting distance range, and the effective shooting angle of the lens 1 is 176 degrees; the light reflected by the object to be shot is transmitted to the lens 1 and focused on the CCD chip 6 through the lens 1, the CCD accumulates corresponding charges according to the intensity of the light, and an electric signal representing a frame of picture is generated through periodic discharge, and a bolt through hole for fixing the base on an automobile or a wall is reserved on the base.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
