Embodiment 1

[0046] Such as Figure 4 As shown, in this embodiment, the number of notches 311 is two, and the two notches 311 are symmetrically arranged on the first cylindrical body 31. It is formed by cutting a part of the barrel wall from the top, so when the lens is placed in the mobile terminal, the two notches are parallel to the rear shell of the mobile terminal, refer to image 3 , when placed in the above manner, the diameter 2*d of the first lens 33 can be increased by 2*(e-f) compared with the diameter of the first lens in the lens module without a notch.

[0047] As a limit, f=0, at this time, the diameter 2*d=c of the first lens 33, at this moment, the circumferential surface of the first lens 33, the notch side wall and the outer side wall of the first cylindrical body 31 form two The plane where the two tips are located is flush, thereby further reducing the aperture value and improving the imaging effect.

[0048] In addition, it should be understood that, in this embodim...

Embodiment 2

[0052] Such as Image 6 As shown, the edge of each notch 311 provided by the embodiment of the present application on the outer side of the first cylindrical body 31 is set as a cut surface 312 . That is, each notch 311 corresponds to a cut surface 312 one-to-one. Taking a notch 311 and the cut surface 312 corresponding to the notch 311 as an example, it can be understood that a part of the side wall of the first cylinder 31 is cut to form a cut surface 312, After that, a notch 311 is opened on the cut surface 312, and the notch 311 communicates with the hollow part of the first cylindrical body 31, or, it can also be understood as, a notch 311 is opened on the side wall of the first cylindrical body 31, and then, A part of the side wall of the first cylinder 31 is cut away to form a cutout 312 , and the cutout passes through the notch 311 , thereby forming a one-to-one correspondence relationship between each notch 311 and the cutout 312 .

[0053] When setting it specifical...

Abstract

The application relates to the technical field of mobile terminals, and discloses a periscope lens module for a mobile terminal and the mobile terminal. The module includes: a motor housing and a lens; the lens includes: a casing, a first lens, and a second lens, wherein the casing includes a first cylinder and a second cylinder connected to the first cylinder, and the second cylinder communicates with the first cylinder. The side wall of a cylinder is provided with at least one notch penetrating the side wall; the first lens is fixed in the first cylinder, and the second lens is fixed in the second cylinder. In the above embodiment, at least one through notch is provided on the side wall of the first cylindrical body, and when the notch is formed, a part of the arc-shaped side wall on the first cylindrical body is cut away. When the lens module is placed in the mobile terminal, the thickness of the mobile terminal affects the diameter of the first lens. Therefore, when placing the lens module, the notch is directed towards the rear shell of the mobile terminal, so that the diameter of the first lens can be increased and the diameter of the first lens can be reduced. The aperture value of the small lens module improves the quality of imaging.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, in particular to a periscope lens module of a mobile terminal and the mobile terminal. Background technique [0002] At present, the horizontal size (vertical optical axis direction) of telephoto lenses in thin and light mobile terminal devices such as mobile phones and tablets is often determined by the front group lens. In order to achieve the purpose of thinning and lightening, telephoto lenses generally adopt a periscope folding structure. Therefore, the horizontal size of the lens determines the height of the module. However, due to the influence of the thickness of mobile terminals such as mobile phones and tablet computers, the height of the module is greatly affected, and there is a strong correlation between the height of the module and the aperture value of the lens, that is, the height of the module determines the aperture of the incident side of the module. The dia...
