Embodiment 1

[0046] like Figure 4 As shown, in this embodiment, the number of the notches 311 is two, and the two notches 311 are symmetrically arranged on the first cylindrical body 31 . It is formed by cutting off a part of the barrel wall. Therefore, when the lens is placed in the mobile terminal, the two notches are parallel to the rear shell of the mobile terminal. 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 of the first lens 33 is 2*d=c. At this time, the circumference of the first lens 33 and the side wall of the gap and the outer side wall of the first cylindrical body 31 form two The plane where each tip is located is flush, thereby further reducing the aperture value and improving the imaging effect.

[0048] In addition, it should be understood that, in this embodiment, the numbe...

Embodiment 2

[0052] like Image 6 As shown, the edge of each gap 311 provided in the embodiment of the present application at 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 cut 311 and the cut surface 312 corresponding to the cut 311 as an example, it can be understood that a cut surface 312 is formed by cutting a part of the side wall of the first cylindrical body 31, After that, a gap 311 is opened on the cut surface 312, and the gap 311 is communicated with the hollow part of the first cylindrical body 31, or, it can also be understood that a gap 311 is opened on the side wall of the first cylindrical body 31, and then, A part of the side wall of the first cylindrical body 31 is cut out to form a cut surface 312 , and the cut surface 312 is passed through the cut surface, so as to form a one-to-one correspondence between each cut surface 311 and the cut surface 312 .

Abstract

The present application relates to the technical field of mobile terminals, and discloses a periscope lens module of a mobile terminal and a mobile terminal. The module includes: a motor casing and a lens; the lens includes: a casing, a first lens and a second lens, wherein the casing includes a first cylindrical body and a second cylindrical body communicated with the first cylindrical body, the first 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 penetrating 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 of the first cylindrical body is cut off. 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 should be oriented 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 image quality.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, and in particular, to a periscope lens module of a mobile terminal and a mobile terminal. Background technique [0002] In the current telephoto lenses in thin and light mobile terminal devices such as mobile phones and tablet computers, the lateral size (vertical optical axis direction) is often determined by the front lens group. Therefore, the lateral size of the lens determines the module height. However, due to the thickness of mobile terminals such as mobile phones and tablet computers, the height of the module is greatly affected, and the height of the module has a strong correlation with the aperture value of the lens, that is, the height of the module determines the light incident side of the module. The diameter of the lens, and the larger the diameter of the lens on the light-incident side of the module, the smaller the aperture value of the lens, and the aperture v...
