Embodiment 1

[0031] Such as figure 1 and figure 2 As shown, the optical lens switching panel 2 is a circular optical lens switching panel 2.3, the center of the circular optical lens switching panel 2.3 is provided with a rotating shaft 2.1, and the output shaft of the motor 5 is connected to the circular optical lens switching panel 2.3 The rotating shaft 2.1 is fixedly connected, and the circular optical lens switching panel 2.3 is uniformly provided with a plurality of lens mounting holes 2.2 along the circumferential direction of the circular optical lens switching panel 2.3, and each lens mounting hole 2.2 is provided with a corresponding switching lens 3.1. For every 45-degree sector of the circular optical lens switching panel 2.3, a switching lens 3.1 is placed, and 8 switching lenses 3.1 can be placed in total, or each sector can be designed to be 60 degrees, so the circular optical lens switching panel 2.3 can be placed in total Place 6 switching mirrors 3.1.

Embodiment 2

[0033] Such as image 3 and Figure 4 As shown, the optical lens switching panel 2 is a fan-shaped optical lens switching panel 2.4, the center of circle of the fan-shaped optical lens switching panel 2.4 is provided with a rotating shaft 2.1, the output shaft of the motor 5 and the rotating shaft 2.1 of the fan-shaped optical lens switching panel 2.4 Fixedly connected, the fan-shaped optical lens switching panel 2.4 is uniformly provided with a plurality of lens mounting holes 2.2 along the circumference of the fan-shaped optical lens switching panel 2.4, and each lens mounting hole 2.2 is provided with a corresponding switching lens 3.1. The sector angle is 135 degrees, and the sector angle of the internal sector disc is 90 degrees, on which two switching lenses 3.1 are placed, each occupying a sector area of ​​45 degrees.

[0034]When the first fixed optical lens 1 is enabled, the focal length of the overall lens is 3mm, which is used when taking pictures normally. When t...

Embodiment 3

[0036] Such as Figure 5 and Figure 6 As shown, it also includes a switch panel peripheral slide rail 7 (the switch panel peripheral slide rail 7 is installed in the corresponding position of the mobile phone), and the optical lens switch panel 2 is a rectangular optical lens switch panel 2.5, and the rectangular optical lens switch panel 2.5 One side of one side is provided with the slide block 8 that matches with the peripheral slide rail 7 of the switching panel, the other side of the rectangular optical lens switching panel 2.5 is provided with a rack 9, and the output shaft of the motor 5 is fixed with a gear 14, so The gear 14 meshes with the rack 9.

[0037] Since the present invention only has a multi-stage zooming function and cannot realize continuous zooming alone, the optical zooming and digital zooming of the present invention can be combined to jointly realize continuous zooming and form infinite zooming.

[0038] A zooming method utilizing the above-mentioned...

Abstract

The present invention relates to a compact zoom lens with switchable focal length, comprising a first fixed optical lens, an optical lens switching panel, and a switchable optical lens group arranged on the optical lens switching panel, wherein the switchable optical lens group includes A plurality of switching lenses with different curvatures and / or different materials, all the switching lenses are located on the same plane, and the optical axis of each switching lens can be aligned with the optical axis of the first fixed optical lens driven by the optical lens switching panel. The lens of the present invention can select the required lenses in the switchable optical lens group according to the needs of taking pictures, thus changing the focal length of the whole lens and further achieving the ability of zooming.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a compact zoom lens with switchable focal length and a zoom method. Background technique [0002] Nowadays, mobile phone photography is more and more convenient and popular, and users' demand for mobile phone photography is getting higher and higher. With the development and evolution of technology, the camera function of mobile phones has been able to meet the needs of high resolution and optimized image quality. Most of them can also support digital zoom, but when the digital "zoom" is larger, the details of the image will be seriously lost, grainy or jagged, and the clarity will be lost. Optical zoom can achieve clear images without losing details when zooming in. The optical zoom function in compact and ultra-thin products such as mobile phones and tablet computers has always been a major technical problem in the industry, but users are looking forward to this functi...
