Abstract

The utility model, which relates to an electric controlling focal length micro-camera, comprises a lens, a CCD module and a shell. The lens is fixed densely at the shell, the image taking end is outside of the shell, the refraction end is arranged in the shell, and the CCD module is arranged at the posterior of the refraction end. The utility model, which is characterized in that the CCD module can do transverse shift, is fixed movably in the shell, and has changed the problem that people are used to find a way to solve the focal length from the lens. The utility model finds a way from the CCD behind the lens and uses various electronic controlled transmission mechanisms skillfully, and the focal length regulation can be realized by regulating the distance between a photographic chip and the lens. The utility model fills up the great difficulty that a high definition of the micro-camera used in various fields cannot be solved, and the utility model which uses the prior art can employ different focal length regulation programs according to different using situations.

Description

A kind of microcam of electric control focusing distance

Technical field

The utility model belongs to a kind of video camera, is a kind of microcam of electric control focusing distance specifically.

Background technology

The alleged microcam of the utility model is meant by built-in 1/4 " or 1/3 " CCD (light signal being converted to the integration module of the signal of telecommunication) or CMS module chip, the microcam that external 2mm or 6mm diameter camera lens constitute, its principle is by the camera lens pickup image, this image refraction is converted to signal of telecommunication output to light signal by the CCD module on CCD.Its focal length of the microcam of this type is fixed in application, definition is that the pitch of armrest adjusting camera lens realizes focusing.Can't obtain best sharpness in the image of change at random, make microcam be subjected to great limitation in each application like this, the object of particularly observing in the motion in micromodule equipment (image) can not reach optimum efficiency.The little special occasions in the space, so type camera realizes focusing at a distance, promotes clearness, and its use value can't be estimated, and can utilize the civilian every field of science and techniques of defence widely, and prospect is infinitely wide.

Summary of the invention

The purpose of this utility model provides a kind of special occasions little in the space, under the situation that does not enlarge the video camera sectional area, has realized the microcam of the electric control focusing distance of automatically controlled adjustment focal length, to overcome above-mentioned deficiency.

To achieve these goals, the utility model is made of camera lens, CCD module and housing, wherein camera lens is close solid on housing, the capture end of camera lens is outside housing, the refraction end is in housing, rear portion at the refraction end is provided with the CCD module, and be characterized in: the CCD module is laterally mobile activity to be fixed in the housing;

Above-mentioned CCD module is fixed in the framework that opening arranged, and the opening part of this framework is embedded with camera lens, opening fixation of C CD module on the right frame inner wall, the framework outer wall on the opening part both sides of framework and be embedded with between the housing both sides inwall of camera lens and be provided with spring;

The framework outer wall end of said fixing CCD module is settled by a lever connecting lever, one end activity of lever connecting lever is fixed on the housing, the framework outer wall end in contact of its top and fixation of C CD module, the other end is inserted in the groove that shell end opens, also be provided with the flexible axle core that can in groove, move in the groove, the flexible axle core is by in the flexible shaft protecting insertion groove, and the outer end of flexible axle core is connected with flexible axle core control device.

The utility model has changed the past people custom and has tried every possible means to solve the problem that focalizes from camera lens, the utility model is to try every possible means from the CCD chip of camera lens back, use various automatically controlled transmission mechanisms dexterously, realize focusing by the distance of adjusting between sensitive chip and the camera lens.Filled up China can not solve high definition in the microcam every field is used a great difficult problem.The utility model can utilize prior art, at different use occasions, can adopt different focusing schemes.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Embodiment

Further specify the utility model below in conjunction with accompanying drawing.

The utility model is owing to be provided with spring 1 between the framework 8 of the housing 7 of fixed lens 4 and fixation of C CD module 2, make framework 8 compressings live the movable top that is fixed on the lever connecting lever 3 on the housing 7, make the movable end compressing groove 9 interior flexible axle cores 5 of lever connecting lever 3, when flexible axle core 5 moves up and down in groove 9, lever connecting lever 3 is rotated along its stiff end, the top of lever connecting lever 3 promotes framework 8 move left and right, distance between CCD module 2 and the camera lens 4 is changed, the process that the process that changes just focalizes promptly reaches the purpose that focalizes.

The effect of flexible shaft protecting 6 of the present utility model is that flexible axle core 5 can be moved up and down in groove 9 easily.The outer end of flexible axle core 5 can connect the cam of a micromachine band, and when the micromachine rotating, this cam driven flexible axle core 5 moves up and down, but both line traffic control of micromachine is also remote-controlled.The utility model control flexible axle core 5 moves up and down, and can also adopt other automatically controlled or remote control mode of prior art.
