The lifting unit comprises a stepping motor, a screw rod, a movable sliding block, a fixed seat, a first connecting rod and a second connecting rod, one end of the screw rod is connected with the fixed seat, the fixed seat is connected with the upper part of the frame shell through the first connecting rod, the other end of the screw rod is connected with the stepping motor, the movable sliding block is in threaded connection with the screw rod, and the movable sliding block is connected with the zooming mechanism through the second connecting rod.
The stepping motor is connected with a motor drive in the mobile equipment.
The image sensor is connected with an image processor in the mobile device.
The image sensor adopts a CMOS image sensor.
The main lens group is provided with a plurality of camera lenses which are vertically arranged.
Compared with the prior art, the utility model discloses technical scheme obtains beneficial effect is:
1. the utility model discloses a principle of reflection makes light not get into image sensor from the camera lens directly like traditional structure, but reflects 90 to the camera lens module erects, can reduce the thickness of camera module by a wide margin like this, possess better camera lens image quality and zoom performance simultaneously;
2. the utility model discloses a zoom principle of combining the camera lens, possess the electrodeless zoom that cell-phone originally did not, can replace all the other cameras in the cell-phone, become a camera by a plurality of cameras, and do not need a plurality of sensors, can control the volume better, save space, reduce cost, more environmental protection;
3. the utility model discloses let the lens group of owner and image sensor depend on step motor and lead screw and reciprocate, so, can realize under the condition of advantages such as the size is less, electrodeless zoom, possess better wide angle performance, more excellent structure and stronger image quality simultaneously;
4. the image sensor can be enlarged better by transversely arranging the image sensor, so that the image quality, the dark light performance and the pixel number are improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Reference numerals: the lens system comprises a frame shell 1, a transmission mirror 2, a reflecting mirror 3, a zoom lens 4, a primary lens group 5, an image sensor 6, a stepping motor 71, a screw rod 72, a movable sliding block 73, a fixed seat 74, a first connecting rod 75 and a second connecting rod 76.
Detailed Description
In order to make the technical problem, technical solution and beneficial effects to be solved by the present invention clearer and more obvious, the following description is made in detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1, the present embodiment includes a frame case 1, a transmission mirror 2, a reflection mirror 3, a zoom lens 4, a primary lens group 5, an image sensor 6, and an elevating unit;
the transmission mirror 2 is arranged in front of the upper part of the frame shell 1, the reflector 3 is arranged at the top end in the frame shell 1, the reflector 3 is arranged towards the transmission mirror 2 and forms an angle of 45 degrees with the transmission mirror 2, the zoom lens 4, the main lens group 5 and the image sensor 6 are sequentially arranged below the reflector 3 in the frame shell 1 from top to bottom, the main lens group 5 is provided with a plurality of camera lenses, and the camera lenses are vertically arranged;
