Description
Technical Field
The utility model relates to a cell-phone camera technical field, concretely relates to lens evagination formula microcephaly camera lens structure.
Background
At present, the mobile phone camera is roughly divided into a screen digging hole and a Liuhai screen, and the screen digging hole is generally accepted by people due to the fact that the screen occupying ratio is improved.
In order to adapt to the structural characteristics of the screen hole digging, the mobile phone camera usually adopts a small-head lens structure, namely the outer diameter of the first lens of the mobile phone camera is very small. The existing small-head lens is the same as other lenses, a structural form that a lens barrel wraps a lens is generally adopted, see fig. 9, but the size of the head of the small-head lens is still larger due to the structural form, when the small-head lens is matched with a mobile phone for use, the problem of the wall thickness of the lens barrel exists outside the lens is solved, under the condition, the hole digging size (see a D2 mark in fig. 9) of a mobile phone screen needs to comprise a small-head lens barrel part, so that the hole opening of the screen is larger, the screen occupation ratio is influenced, the purpose of achieving a full screen is not facilitated, and the appearance is not facilitated.
CN211180368U discloses a lens module, which includes a lens barrel with a receiving space and a lens set received in the receiving space. The lens group comprises a first lens positioned on the object side, wherein the first lens comprises an optical part for imaging and a bearing part arranged around the optical part. Wherein, the optical part at least partially protrudes out of the accommodating space. The bearing part comprises a top surface close to the object side, the optical part comprises an object side surface close to the object side and a side surface connecting the object side surface and the top surface, and the side surface and the top surface form a step structure to be abutted with the lens barrel. The lens module further comprises a shading sheet attached to the side surface. In order to solve the problem that the wall thickness of the lens barrel is reduced and the screen occupation ratio is reduced, at least part of the first lens is not wrapped in the lens barrel, and in order to avoid stray light which interferes with imaging and is generated at a position outside the effective diameter of the first lens, a shading sheet is additionally arranged. It has reached design original intention to a certain extent, still has the following problem:
1. the shading sheet is sleeved on the surface of the outer side surface of the first lens, and can only be formed into a conical cylinder shape or a straight cylinder shape with a straight bus line due to self characteristics and production process, namely, the shading sheet can only shade the straight surface of the outer side of the first lens, so that stray light is avoided. The transition position (right angle or fillet) of the outer side straight surface of the first lens and the bearing part thereof, and the transition position (fillet) of the outer side straight surface of the first lens and the effective diameter part thereof can also generate veiling glare, but the shading sheet can not realize avoidance through shading, so that the imaging quality of the lens is greatly influenced.
2. The difficulty of manufacturing the shading sheet is high, namely the size of the shading sheet must ensure that the shading sheet is tightly attached to the first lens, otherwise, stray light cannot be avoided.
3. The gobos have no universality, the size of the first lens can be changed for different types of lenses, and the gobos are required to be equipped in a plurality of types.
4. The light shading sheet can not form a diaphragm on the first lens, and only can be additionally provided with a diaphragm in the lens.
5. The size of the bearing part of the first lens is larger than the opening size of the top surface of the lens barrel, so that the first lens can only be installed in the lens barrel from the image side, the process method for assembling the lens is restricted, meanwhile, in order to limit the first lens, the top surface end of the lens barrel needs to be provided with a limiting part, but because the lens barrel is usually integrally formed, the size of the limiting part needs to be adapted to the whole size and is thicker, the first lens is longer to a certain extent, the size of the lens is increased, and the arrangement of the internal structure of the mobile phone is not facilitated.
