Abstract

The invention relates to a structure of a lens-exposed periscopic minimal-head lens, which comprises a first lens group, a second lens group and a third lens group; a first lens group is arranged above the second lens group; the right side of the second lens group is provided with a third lens group. The first lens of the first lens group protrudes out of the lens barrel. The second lens group is a right-angle triangular prism. The third lens group is an aspheric lens group with more than 4 lenses. The invention effectively reduces the overall height of the lens, correspondingly can reduce the overall thickness of the mobile phone, and can increase the screen occupation ratio when the head is smaller. The invention reduces the difficulty of assembling the lens of the prism mobile phone, and the whole lens is more convenient to assemble. The invention reduces the coaxiality tolerance of the light through hole generated by using the cover plate.

Description

Structure of lens-exposed periscopic extremely small-head lens

Technical Field

The invention relates to the technical field of design of a lens mechanism of a mobile phone camera, in particular to a structure of a periscopic extremely small-head lens with an exposed lens.

Background

With the development of the mobile phone industry, the pursuit of people for the use of mobile phones is continuously changed, and the requirements on mobile phone lenses are higher and higher. To achieve a higher duty ratio, prisms are used to reduce the head size to meet the higher duty ratio requirements.

Disclosure of Invention

The invention aims to provide a structure of a lens-exposed periscopic small-head lens, which is characterized in that a first prism sheet is made into an exposed type, so that the overall height of the lens can be further shortened, and the thickness of a mobile phone can be reduced.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a structure of a lens-exposed periscopic extremely small head lens comprises a first lens group, a second lens group and a third lens group; a first lens group is arranged above the second lens group; the right side of the second lens group is provided with a third lens group.

The invention has the beneficial effects that:

1. the invention effectively reduces the overall height of the lens, correspondingly can reduce the overall thickness of the mobile phone, and can increase the screen occupation ratio when the head is smaller.

2. The invention reduces the difficulty of assembling the lens of the prism mobile phone, and the whole lens is more convenient to assemble.

3. The invention reduces the coaxiality tolerance of the light through hole generated by using the cover plate.

Fig. 1 is an overall structural view of the present invention.

Detailed Description

The invention is described in further detail below with reference to the accompanying figure 1.

A structure of a lens-exposed periscopic minimal head lens comprises a first lens group 1, a second lens group 2 and a third lens group 3; a first lens group 1 is arranged above the second lens group 2; the right side of the second lens group 2 is provided with a third lens group 3; the first lens P1 of the first lens group 1 protrudes out of the lens barrel.

The second lens group is a right-angle triangular prism.

The third lens group is an aspheric lens group with more than 4 lenses.

The second lens group and the first lens group are assembled from top to bottom, and the second lens group and the third lens group are assembled from right to left.

The structure bearing part of the first lens P1 is higher than the edge of the lens barrel; the parts except the P1 aspheric surface are subjected to sand blasting and ink coating to improve veiling glare.

The first lens P1 structure leaning part is higher than the edge of the lens cone. The parts of the first lens P1 except the aspheric surface are sand-blasted and inked to improve veiling glare. The height of the protruding bearing part of the first lens P1 is H, and the outer diameter of the first lens P1 is H

Then

The prism lens is a right-angle isosceles prism. The total number of the lens pieces P is more than or equal to 6.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.
