Problems solved by technology

Since the plastic lens made by this method is integrally formed with the raised structure of the edge, the process of assembling the spacer is omitted; however, when the plastic lens is made, the edge of the lens is formed The convex structure needs to take into account the stress change of plastic forming, which will make the forming of plastic lenses more difficult and the process is more difficult

Embodiment Construction

[0014] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] Referring to FIGS. 1 and 2 , an embodiment of the present invention provides a lens barrel 10 , which includes a cylindrical main body 100 , a front end 102 of the lens barrel, a plurality of bending portions 104 and a holding portion 106 .

[0016] The main body 100 has external threads 1002 formed on its outer surface. The main body 100 is used for accommodating optical elements such as lenses and filters, and its material can be engineering plastics such as polyethylene, polypropylene, polyvinyl chloride or polystyrene.

[0017] The front end 102 of the lens barrel is located at one end of the cylindrical main body 100 , the front end 102 of the lens barrel and the main body 100 are integrally formed, and it also has a funnel-shaped incident light whose diameter gradually changes along the thickness of the front end 102 of the len...

Abstract

The lens cone for containing optical components comprises a cylinder body and a lens cone front at one end of the body, features in several folded section and fixed holding section spaced along the circumference of the body at the other end of the circumference, with the folding section and the fixed section stretching along the axis of the body, with the said folding section inwardly folding to form the compartment along the radius of the body. It also provides a lens module set of the said lens cone, forming protruding structures free from barricade gasket or optical components at the ridge with less assembly process and less difficult manufacturing process.

Description

【Technical field】 [0001] The invention relates to a lens barrel and a lens module using the lens barrel, which can be applied in the field of imaging systems. 【Background technique】 [0002] A lens module is an important part of an imaging system, such as a digital camera, and includes components such as a lens and a cylindrical lens barrel. Most lens modules also include optical elements such as filters to change the light conditions of the imaging system during shooting, enhance the contrast, and improve the shooting effect. In the lens module, it is usually necessary to provide intervals between the various optical elements to avoid wear of adjacent optical elements due to mutual friction or collision, thereby preventing the optical performance of the optical elements from deteriorating. [0003] In the prior art, a method for forming a space between the lens and the filter is disclosed, that is, in the assembly process of the lens module, an annular spacer is used to ar...
