For convenience of understanding the technical solution in the present embodiment, the periscopic lens module is first described below with reference to the accompanying drawings.

As shown in fig. 1, fig. 1 shows a schematic structural diagram of a lens module. The structure of the lens module comprises: the device comprises a reflector 2 or a reflecting prism 2.1, a lens 3, a filter 4, an image sensor 5, a signal processing module 6 and a display module 7. The imaging principle is as follows: the imaging light 1 enters the lens 3 after being refracted by the reflecting prism 2 or the reflecting mirror 2.1 (the reflecting prism 2 and the reflecting mirror 2.1 have the same function), the lens 3 has the function of converging and imaging the light 1, and redundant light waves (such as light waves except visible light) in the light 1 are filtered out through the optical filter 4 and finally converged at the image sensor 5; the signal processing module 6 controls the image sensor 5 to perform photoelectric conversion on the collected optical signals, and the optical signals are transmitted to the display module 7 for display after being processed.

In addition, in addition to the hardware, the lens module further includes: the focusing motor is used for adjusting the position of the lens to shoot objects with different distances; the anti-shake motor is used for adjusting the position of the lens, so that the photographed object can not cause image blurring due to hand shake of a user and the like. A system control device: the system comprises a photographing control for setting a photographing mode, such as a black and white mode, a high dynamic mode and the like; the focusing control is used for controlling the focusing motor to realize automatic focusing; and the anti-shake control is used for controlling the anti-shake motor to stably shoot images. The focusing motor, the anti-shake motor, the system control device, etc. are similar to the functions of the lens module in the mobile terminal in the prior art, and are not described in detail herein.

In a specific use, as shown in fig. 2, which shows a schematic diagram of a lens module and a mobile terminal, the lens module is horizontally disposed in the mobile terminal, that is, the reflector 2 or the reflecting prism 2.1, the lens 3, and the filter 4 (light in the propagation direction of the imaging lens module) are arranged along the width direction of the mobile terminal. And when the mobile terminal is specifically arranged, the shell 8 of the motor (focusing motor) is fixed in the mobile terminal, and a certain focusing gap is formed between the lens 3 and the big shell 8. Since the aperture value of the lens module is directly related to the quality of photographing, such as resolution, low-light imaging capability, etc., and the aperture value is determined by the diameter of the lens at the front end of the lens module, in the present application, the lens in the lens module is improved to achieve the effect of improving the imaging quality.

Specifically, the structure of the lens in the periscopic lens module is improved, and when the lens is specifically arranged, the lens is placed in a shell of a motor (a focusing motor); the lens barrel includes a housing, a first lens 33, and a plurality of second lenses. Specifically, as shown in fig. 4, the housing includes a first cylinder 31 with a larger diameter and a second cylinder 32 with a smaller diameter, the first cylinder 31 and the second cylinder 32 are communicated and coaxially disposed, the first lens 33 is disposed in the first cylinder 31 with a larger diameter, the plurality of second lenses are disposed in the second cylinder 32, and the first lens 33 and the plurality of second lenses are coaxially disposed, wherein the first lens 33 is a lens on the light incident side, that is, the first lens 33 receives the reflected light 1 and then propagates to the second lens. Referring to fig. 2 and 3 together, when the first lens 33 is a lens on the light incident side, the aperture value is determined by the size of the first lens 33, and when the diameter of the first lens 33 is larger, the aperture value is smaller, and the imaging quality is better. Therefore, in order to increase the diameter of the first lens 33, it is necessary to utilize the space in the motor housing to the maximum, and in the present application, in order to increase the diameter of the first lens 33, at least one notch 311 penetrating the first cylindrical body 31 is provided on the side wall of the first cylindrical body 31, and the notch 311 is formed by cutting a part of the side wall of the first cylindrical body 31, so that the distance from the center of the first lens 33 to the position where the notch is formed on the outer side wall of the first cylindrical body 31 is smaller than the distance from the center of the first lens 33 to the position where the notch is not formed on the outer side wall of the first cylindrical body 31. Referring to fig. 2 together, when the lens is placed specifically, the notch faces the thickness direction of the mobile terminal, so that, by adopting the notch, the size of the first cylinder 31 in the thickness direction of the mobile terminal is reduced, and the size in the thickness direction of the mobile terminal is the main size for limiting the size of the first cylinder 31, so that, after the notch reduces the size of the first cylinder 31 in the rear end direction of the mobile terminal, the size of the first cylinder 31 can be made larger, and further the size of the first lens 33 can be made larger.

For the convenience of understanding the principle of the lens module provided in the present application, the following detailed description is made with reference to fig. 3. Fig. 3 is a schematic diagram illustrating a comparison between a lens module of the present application and a lens module of the prior art placed in a mobile terminal; the lens module on the left side is the lens module of the present application, the first cylinder 31 of the lens module only adopts one notch 311, and the lens module on the right side is the lens module without a notch on the first cylinder; the two horizontal lines in the figure are two parallel auxiliary lines, and the two auxiliary lines are used for helping to understand the width size occupied by the lens module in the thickness direction of the mobile terminal, wherein the two parallel lines are respectively tangent to the two cylinders, and the distance c between the two parallel lines is the width occupied by two different lens modules in the thickness direction of the mobile terminal. As can be seen from fig. 3, in the lens module of the present application, c is the diameter 2 × d of the first lens + the thickness e of one sidewall of the first cylindrical body 31 + the distance f from the sidewall of the first lens to the notch 311; in the right lens module, c is the lens diameter 2 × D + the sidewall thickness E × 2 of the cylinder. When the lateral wall thickness of the cylinder on first cylinder 31 in this application is unanimous with the lateral wall thickness of the cylinder on right side, because breach 311 is for excising some structure formation on the lateral wall of first cylinder 31, therefore, f < E, thereby can realize when numerical value c (the width that the camera lens occupy at mobile terminal thickness direction promptly) is unchangeable, the diameter D of first lens 33 in this application is greater than the value of the diameter D of the first lens on right side, therefore, in the technical scheme that this application provided, first cylinder 31 adopts the structural style of non-circular symmetry, can effectual increase the diameter of first lens 33, thereby make full use of motor shell's inner space, reduce the camera lens aperture value, promote camera lens optical property, promote the experience of shooing.

As a limit, f is 0, in this case, the diameter 2 × d of the first lens 33 is c, and in this case, the circumferential surface of the first lens 33 is flush with the plane where the two tips formed by the notch side wall and the outer side wall of the first cylindrical body 31 are located, so that the aperture value is further reduced, and the imaging effect is improved.

Further, it should be understood that in the present embodiment, the number of the notches 311 is not limited to two, and may be any number of notches 311 such as four, six, etc., as shown in fig. 5, which shows the case of using four notches 311. When the plurality of notches 311 are adopted, the lens module can be conveniently fixed when being placed in the mobile terminal, namely, any two opposite notches 311 are adopted to be matched with the mobile terminal.

When the notch is formed on the side wall of the first cylinder 31, the first cylinder 31 encloses a non-circular space, and when the first lens 33 is placed in the first cylinder 31, due to machining errors and assembly errors, eccentricity occurs, and in order to ensure the installation accuracy of the first lens 33, preferably, referring to fig. 8, the lens module further includes a first fixing member 332, and the first fixing member 332 is embedded in the second cylinder 32 and is used for fixing the first lens 33.

In a specific embodiment, as shown in fig. 7, as an extreme case, the distance from the center of the first lens 33 to the tangent plane 312 is equal to the radius of the first lens 33, and each tangent plane 312 is the tangent plane of the first lens 33. With this configuration, the space in the motor housing can be utilized to the maximum, that is, the diameter of the first lens 33 can be increased to the maximum, thereby reducing the aperture value and improving the imaging effect.

It should be understood that, whichever of the above solutions is adopted, the notch 311 may also serve as a structure for fixing the first lens 33 at the time of the specific setting.

In order to avoid the assembly difficulty caused by the excessive friction distance between the notch 311 and the second fixing member 331 during the insertion of the first lens 33, in another specific embodiment, the notch 311 may be a step-shaped notch 311, as shown in fig. 9, each notch 311 is a convex notch, specifically, the notch 311 is in a shape of a "convex", but the boundary of the "convex" is not strictly limited, as shown in fig. 9, the notch 311 is located at one end of the first cylindrical body 31 on the light incident side, and the notch 311 forms an opening at one end of the first cylindrical body 31 on the light incident side. And the smaller open end of the notch 311 is adjacent to the second cylinder 32. I.e. the cut-out opening at the port of the first cylinder 31 is larger and the cut-out opening at the side closer to the second cylinder 32 is smaller, the second fastener 331 being adapted to cooperate with the cut-out having a smaller opening. When the first lens 33 is inserted, there is sufficient clearance between the notch having the large opening and the second fixing member 331 so that the first lens 33 is inserted into the first cylindrical body 31, and the first lens 33 and the notch are engaged only at the last position where the first lens 33 needs to be fixed.
