Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.

In the related art, in order to improve the shooting effect of a camera of an electronic device such as a mobile phone under low light, the aperture design of the camera is gradually increased, but the problem of overexposure, flickering stripes under an alternating current light source, and blurred short-distance shooting edges under a large aperture and a shallow depth of field also can be caused when the aperture is too large under a normal environment or a bright environment.

Fig. 1 is a schematic view illustrating an assembly structure of a lens module according to an exemplary embodiment of the disclosure; fig. 2 is an exploded schematic view of a lens module according to an exemplary embodiment of the disclosure. As shown in fig. 1 and 2, the lens module 1 includes: the diaphragm switching mechanism 11 and at least one first lens 12, the diaphragm switching mechanism 11 and the first lens 12 are assembled to form an assembly 14. The first lens 12 includes a first barrel 122 and a first lens group 121 assembled to the first barrel 122, and at least a portion of the first lens group 121 protrudes from the first barrel 122 in an axial direction of the lens module 1. The diaphragm switching mechanism 11 includes a mechanism body 111, an assembly space 112 defined by the mechanism body 111 and disposed along an axial direction of the first lens 12, and an insertion space 112 into which at least a portion of the first lens 12 is fixedly inserted, so that a first axial length d1 of the assembly 14 is smaller than a sum of a second axial length d2 of the diaphragm switching mechanism 11 and a third axial length d3 of the first lens 12.

In this embodiment, since the lens module 1 includes the first lens 12 and the diaphragm switching mechanism 11, the diaphragm switching mechanism 11 can adaptively change the size of the diaphragm under different light environments, and switch to a large diaphragm in a dark environment, so as to ensure sufficient light input, reduce noise, improve dark state effect, and obtain clear images. The bright environment time switches to little light ring to guarantee each visual field definition, avoid simultaneously because of the scintillation stripe problem under the alternating current light source that big light ring short exposure caused, promoted lens module 1's shooting effect. The mechanism body 111 of the iris switching mechanism 11 encloses an assembly space 112 disposed along the axial direction of the first lens 12, at least a portion of the first lens 12 is embedded in the assembly space 112, and the portion of the first lens 12 embedded in the assembly space 112 does not occupy the axial thickness, thereby reducing the overall thickness of the lens module 1. In addition, as shown in fig. 3, at least a portion of the first lens group 121 protrudes out of the first barrel 122 in the axial direction of the lens module 1, so as to reduce the length of the first barrel 122, which not only reduces the overall length of the first lens 12, but also reduces the space occupation of the first barrel 122 to the assembly space 112, thereby facilitating to increase the insertion depth of the first lens 12 and reduce the first axial length d1 of the assembly 14.

The length of the first lens 12 inserted into the assembly space 112 and the first lens barrel 122 is reduced, so that the first axial length d1 of the assembly 14 formed by the first lens 12 and the diaphragm switching mechanism 11 is smaller than the sum of the second axial length d2 of the diaphragm switching mechanism 11 and the axial length of the first lens 12, the overall thickness of the assembly 14 is reduced, and the lightness and thinness of the lens module 1 and the electronic device using the lens module 1 are improved.

It should be noted that the dotted line in fig. 1-7 may represent the optical axis direction of the first lens 12, the axial direction of the first lens 12 may be the optical axis direction of the first lens group 121 of the first lens 12, and the third axial length d3 of the first lens 12 may refer to the length of the first lens 12 in the optical axis direction. The second axial length d2 of the diaphragm switching mechanism 11 may refer to a length of the diaphragm switching mechanism 11 in the optical axis direction, and the first axial length d1 of the assembly 14 may refer to a length of the assembly 14 formed by the first lens 12 and the diaphragm switching mechanism 11 in the optical axis direction. At least a portion of the first lens group 121 protrudes from the first barrel 122 in the axial direction of the lens module 1, which means that the first lens group 121 protrudes from an end surface 1221 of the first barrel 122 facing the aperture switching mechanism 11 in the axial direction of the lens module 1. For example, the portion of the first lens group 121 protruding from the first lens barrel 122 may be an arc-shaped structure, and the arc-shaped structure protrudes from an end surface 1221 of the first lens barrel 122 facing the aperture switching mechanism 11. In other embodiments, as shown in fig. 4, the first lens group 121 of the first lens barrel 12 can also be accommodated in the first lens barrel 122.

In the above embodiment, part or all of the structure of the first lens 12 can be fixedly accommodated in the assembly space 112, so that the part of the first lens 12 embedded in the assembly space 112 does not occupy the axial thickness, thereby reducing the overall thickness of the lens module 1. When the entire structure of the first lens 12 is inserted into the assembly space 112, the first lens 12 and the diaphragm switching mechanism 11 form an integrated assembly 14, and the overall structural layout of the assembly 14 is optimized, thereby further reducing the overall thickness of the lens module 1.

In some embodiments, as shown in fig. 3-6, the lens module 1 may further include at least one second lens 13 assembly, the second lens 13 assembly is fixed to the first lens 12 and/or the iris switching mechanism 11, and an optical axis of the second lens 13 assembly coincides with an optical axis of the first lens 12. That is, the lenses of the lens module 1 can be grouped to obtain the first lens 12 and the second lens 13, and the height of the first lens barrel 122 of the first lens 12 can be conveniently shortened and adjusted after the lens is grouped, so that the influence of the height reduction of the lens barrel on the lens assembly of the lens module 1 is avoided.

In the above embodiment, as shown in fig. 5 and fig. 6, the second lens 13 assembly may include at least one second lens 13, the first lens 12 includes an insertion end 124 and an assembly end 125, which are axially opposite to each other, the insertion end 124 is accommodated in the assembly space 112, and the assembly end 125 is assembled with the second lens 13. The axial direction may be an optical axis direction of the first lens group 121 of the first lens 12, and the diaphragm switching mechanism 11 and the second lens 13 are respectively disposed at two ends of the first lens 12. For example, the second lens 13 assembly may include a second lens 13, and the second lens 13 is fixedly connected to the assembling end 125 of the first lens 12, so that the first lens 12 and the second lens 13 cooperate to achieve a corresponding lighting effect.

At least a portion of the second lens group 131 protrudes from the second barrel 132 in the axial direction of the lens module 1, which means that the second lens group 131 protrudes from the end surface 1321 of the second barrel 132 in the axial direction of the lens module 1. When at least a portion of the second lens group 131 protrudes out of the second lens barrel 132, the length of the second lens barrel 132 can be reduced, which not only reduces the overall length of the second lens 13, but also reduces the axial length of the second lens 13 occupied by the second lens barrel 132, thereby contributing to reducing the overall thickness of the lens module 1. In addition, the second lens 13 and the first lens 12 may be fixedly connected by means of adhesive dispensing, clamping, or threaded connection, which is not limited in this disclosure.

In an embodiment, the second connection portion 123 may be disposed at one end of the first barrel 122, so that the first connection portion 113 and the second connection portion 123 may realize a snap fit after the first lens 12 is inserted into the assembly space 112.

The locking groove comprises a radial matching surface and an axial matching surface which are abutted to the locking block, so that the first lens 12 and the diaphragm switching mechanism 11 are limited along the axial direction and the radial direction of the first lens 12.

In some embodiments, as shown in fig. 7, the mechanism body 111 of the aperture switching mechanism 11 may include a housing 1111 and a control assembly 1112.
