Description

Periscope type lens, periscope type camera module, manufacturing method of periscope type camera module, periscope type array module and electronic equipment
Technical Field
The invention relates to the technical field of camera modules, in particular to a periscope type lens, a periscope type camera module, a manufacturing method thereof, a periscope type array module and electronic equipment.
Background
With the progress of the science and technology and the development of economy, the requirements of people on the camera shooting function of portable electronic equipment (such as tablet personal computers, ipad, smart phones and the like) are higher and higher, so that not only can the camera shooting module arranged on the electronic equipment realize background blurring and clear shooting at night, but also the camera shooting module arranged on the electronic equipment can realize optical zooming. The periscope type array camera shooting module is taken as a camera shooting module with higher optical zoom capability, and is popular and valued more and more.
At present, the existing periscope type array module is generally formed by combining a periscope type long-focus camera module and a vertical type wide-angle camera module. The periscope type long-focus camera shooting module is characterized in that a prism is added at the front end of a conventional long-focus camera shooting module, light rays entering the end part of the camera shooting module are reflected or refracted to change the direction of the light rays and then enter the camera shooting module, so that the conventional long-focus camera shooting module can be installed in a horizontal mode (namely, the conventional long-focus camera shooting module is horizontally placed), and the height of the camera shooting module is reduced. In addition, when the optical zoom capability of the periscope type long-focus camera module is improved by increasing the module focal length of the periscope type long-focus camera module, the length of the periscope type long-focus camera module is prolonged, the height of the periscope type long-focus camera module is not increased, and accordingly, the height of the periscope type array module is not increased, so that the thickness of the electronic equipment provided with the periscope type array module can be prevented from being increased.
However, in order to meet the trend of the current electronic devices, the height of the periscope type array module needs to be further reduced, i.e. the height of the periscope type tele camera module needs to be further reduced. In the design of the existing periscope type long-focus camera module, the optical lens of the existing periscope type long-focus camera module comprises a group of lenses and a lens barrel, wherein the lens barrel covers the group of lenses, the size of a first lens in the group of lenses is larger than that of other lenses in the group of lenses, so that the height of the optical lens is slightly larger than that of the first lens, and further the height of the existing periscope type long-focus camera module is inevitably larger than that of the first lens, therefore, the height of the existing periscope type long-focus camera module cannot be further reduced, the requirement of the current electronic equipment on the light and thin development cannot be met, and the application and popularization of the periscope type long-focus camera module in various electronic equipment are greatly limited.

In this specification, schematic representations of the above terms are not necessarily directed to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, the different embodiments or examples described in this specification and the features of the different embodiments or examples may be combined and combined by those skilled in the art without contradiction.
Referring to fig. 1 to 10 of the drawings, a periscope type array module according to a first preferred embodiment of the present invention is illustrated. As shown in fig. 1, the periscope type array module 1 includes at least one periscope type camera module 10 and at least one upright type camera module 20, wherein the periscope type camera module 10 and the upright type camera module 20 are combined so as to form the periscope type array module 1 with different assembly layouts, and the periscope type array module 1 has an optical zoom function.
It should be noted that, although the description of fig. 1 to 10 and the following description take the periscope type array module 1 as an example, only one periscope type camera module 10 and one upright type camera module 20 are included in the periscope type array module 1 of the present invention, it should be understood by those skilled in the art that the periscope type array module 1 disclosed in fig. 1 to 10 and the following description is merely an example, and does not limit the content and scope of the present invention, for example, in other examples of the periscope type array module, the periscope type camera module 10 and the upright type camera module 20 may be more than one in number to improve the photographing effect of the periscope type array module 1.
It should be noted that, in the first preferred embodiment of the present invention, the effective focal length of the upright camera module 20 is smaller than the effective focal length of the periscope camera module 10, that is, the Field of View (FOV) of the upright camera module 20 is larger than the Field of View of the periscope camera module 10. In other words, in the present invention, the vertical camera module 20 is configured as a wide-angle camera module, the periscope camera module 10 is configured as a tele camera module, and the range of view of the vertical camera module 20 is wider and wider during the shooting process using the periscope array module, but the details of distant objects are difficult to shoot, while the range of view of the periscope camera module 10 is narrower, but objects that are relatively farther can be shot, so that the function of "optical zoom" is realized by the complementary matching of the vertical camera module 20 and the periscope camera module 10. It should be understood that, in the present invention, the type of the upright camera module 20 is not limited, for example, the upright camera module 20 may be a well-known camera module such as a wide-angle camera module, a standard camera module, or a telephoto camera module, which is not repeated herein.
According to the first preferred embodiment of the present invention, as shown in fig. 1, the periscope type camera module 10 includes a photosensitive assembly 11, a periscope type lens 12 and a light turning assembly 13, wherein the periscope type lens 12 and the light turning assembly 13 are both held in a photosensitive path of the photosensitive assembly 11, and the periscope type lens 12 is located between the photosensitive assembly 11 and the light turning assembly 13. The light steering component 13 can change the direction of an imaging light ray entering the light steering component 13, and enable the turned imaging light ray to pass through the periscope lens 12 along a photosensitive path of the photosensitive component 11 and then be received by the photosensitive component 11 for imaging, that is, the light steering component 13 can enable the imaging light ray to pass through the periscope lens 12 after being turned so as to be received by the photosensitive component 11 for imaging. It should be understood that the imaging light may be implemented as ambient light reflected by a space object, or as light emitted by the space object itself, and the type of the imaging light is not limited in the present invention, so long as the imaging light can be received by the photosensitive module 11 to form an image.
Preferably, as shown in fig. 1 to 3, the light-turning component 13 is capable of turning the light by 90 degrees so that the light perpendicular to the light-sensing path of the light-sensing component 11 is parallel to the light-sensing path of the light-sensing component 11 after being turned by the light-turning component 13, so that when the periscope type array module 1 is mounted to an electronic device body 500 to be assembled into an electronic device, the upright type camera module 20 is mounted to the electronic device body 500 in a "upright" mounting manner, and the periscope type camera module 10 is mounted to the electronic device body 500 in a "recumbent" mounting manner, so as to reduce the height of the periscope type array module 1, and prevent the height of the periscope type array module 1 from being greater than the height of the electronic device body 500 (i.e., the thickness of the electronic device body 500), thereby conforming to the current trend of light and thin electronic devices.
Illustratively, as shown in fig. 2A, after the periscope type array module 1 is assembled to an electronic apparatus body 500 to be assembled into an electronic apparatus, the upright type camera module 20 is disposed along a height direction of the electronic apparatus body 500, and the photosensitive assembly 11, the periscope type lens 12, and the light steering assembly 13 of the periscope type camera module 10 are disposed along a width direction of the electronic apparatus body 500, respectively, so that an optical axis direction of the periscope type lens 12 is parallel to the width direction of the electronic apparatus body 500, thereby enabling to prevent an end surface of the periscope type lens 12 from protruding from a front surface or a rear surface of the electronic apparatus body 500 due to an excessively long length of the periscope type lens 12, or to increase a height (i.e., thickness) of the electronic apparatus body 500. In other words, the height (i.e., thickness) of the electronic device body 500 is limited only to the height of the periscope lens 10, irrespective of the length or width of the periscope lens 10, so that the structure of the periscope image capturing module 10 of the present invention is particularly suitable for the periscope lens 12 of tele.
As shown in fig. 2B, after the periscope type array module 1 is assembled to an electronic device body 500 to form an electronic device, the upright type camera module 20 is disposed along the height direction of the electronic device body 500, and the photosensitive assembly 11, the periscope type lens 12 and the light steering assembly 13 of the periscope type camera module 10 are disposed along the length direction of the electronic device body 500, respectively, so that the optical axis direction of the periscope type lens 12 is parallel to the length direction of the electronic device body 500, and it is possible to prevent the end surface of the periscope type lens 12 from protruding from the front surface or the rear surface of the electronic device body 500 due to the overlong length of the periscope type lens 12, or to increase the height (i.e., thickness) of the electronic device body 500. In other words, the height (i.e., thickness) of the electronic device body 500 is limited only to the height of the periscope lens 10, irrespective of the length or width of the periscope lens 10, so that the structure of the periscope image capturing module 10 of the present invention is particularly suitable for the periscope lens 12 of tele.
It should be noted that, although fig. 2A and 2B of the drawings illustrate the electronic device body 500 as a smart phone body, features and advantages of the periscope type array module 1 of the present invention are described, those skilled in the art should understand that the smart phone body illustrated in fig. 2A and 2B is merely an example, and does not limit the content and scope of the present invention, for example, in other embodiments of the present invention, the electronic device body 500 may be implemented as other electronic device bodies such as Ipad, a tablet computer, a notebook computer, etc.
However, as the development progress of the light and thin electronic devices is deepened, the height of the periscope type camera module 10 still becomes a significant obstacle for the height (i.e. thickness) of the electronic devices to be reduced, so that how to reduce the height of the periscope type camera module 10 has become a problem to be solved. It should be noted that, since the height of the periscope lens 12 directly determines the height of the periscope image capturing module 10, in the first preferred embodiment of the present invention, the structure of the periscope lens 12 is designed to reduce the height of the periscope lens 12, so as to achieve the effect of reducing the height of the periscope image capturing module 10.
Specifically, as shown in fig. 3 to 5, the periscope lens 12 of the periscope image capturing module 10 includes a lens barrel 121, a first lens group 122 and a second lens group 123, and the radial dimension of the first lens group 122 is larger than the radial dimension of the second lens group 123, wherein the first lens group 122 and the second lens group 123 are coaxially disposed on the lens barrel 121, and the first lens group 122 and the second lens group 123 are located on the photosensitive path of the photosensitive assembly 11, wherein the outer periphery of the first lens group 122 is partially covered by the lens barrel 121, and the outer periphery of the second lens group 123 is completely covered by the lens barrel 121, so that the height of the periscope lens 12 is not larger than the radial dimension of the first lens group 122.
It should be noted that, although the description of fig. 1 to 10 and the following description take the first lens group 122 including one lens and the second lens group 123 including four lenses as examples, features and advantages of the periscope type camera module 10 of the present invention are described, it should be understood by those skilled in the art that the periscope type camera module 10 disclosed in fig. 1 to 10 and the following description is merely exemplary, and does not limit the content and scope of the present invention, for example, in other examples of the periscope type camera module 10, the number of lenses included in the first lens group 122 may be two or more, and the number of lenses included in the second lens group 123 may be one. In addition, the first lens group 122 and/or the second lens group 123 may include only a convex lens, only a concave lens, and both a convex lens and a concave lens, so as to achieve the desired light effect of the periscopic lens 12, which is not limited in the present invention.
More specifically, as shown in fig. 3 and 5, the lens barrel 121 is provided with a light channel 1211, wherein the light channel 1211 extends along the light sensing path of the light sensing assembly 11 to allow the diverted imaging light to pass through the lens barrel 121 along the light channel 1211, and wherein the first lens group 122 and the second lens group 123 are coaxially mounted to the light channel 1211 of the lens barrel 121 such that the first lens group 122 and the second lens group 123 are located in the light sensing path of the light sensing assembly 11, such that the diverted imaging light is received by the light sensing assembly 11 to be imaged after passing through the first lens group 122 and the second lens group 123.
Notably, of all the lenses of the periscope lens 12 of the periscope camera module 10, the radial dimension of the lens closer to the light redirecting assembly 13 is generally greater than the radial dimension of the lens farther from the light redirecting assembly 12. Thus, in the first preferred embodiment of the present invention, as shown in fig. 3 and 5, the lens barrel 121 further has a first end 1212 adjacent to the light-redirecting component 13 and a second end 1213 adjacent to the photosensitive component 11, wherein the light channel 1211 extends from the first end 1212 of the lens barrel 121 to the second end 1213 of the lens barrel 121, and the first lens group 122 is located at the first end 1211 of the lens barrel 121, and the second lens group 123 is located at the second end 1212 of the lens barrel 121, such that the imaging light redirected by the light-redirecting component 13 passes through the first lens group 122 and then passes through the second lens group 123 before being received by the photosensitive component 11 for imaging. In other words, the first lens group 122 of the optical lens 12 is located between the light steering assembly 13 and the photosensitive assembly 11, and the second lens group 123 is located between the first lens group 122 and the photosensitive assembly 123, so that the imaging light beam that is steered by the light steering assembly 13 passes through the first lens group 122, then passes through the second lens group 123, and finally is received by the photosensitive assembly 11 to be imaged.
It should be noted that, in the existing periscope type image capturing module, since the lens barrel of the optical lens of the existing periscope type image capturing module completely covers the outer peripheral edges of all lenses, and the lens barrel itself has a corresponding thickness, the height of the optical lens of the existing periscope type image capturing module is inevitably larger than the radial dimension (or diameter) of all lenses.
However, in the periscope type photographing module 10 according to the first preferred embodiment of the present invention, as shown in fig. 5, the lens barrel 121 of the periscope type lens 12 of the periscope type photographing module 10 partially covers the outer circumference of the first lens group 122, and the upper and lower edges of the first lens group 122 are not covered by the lens barrel 121, so that the height of the periscope type lens 12 can be reduced to be equal to the radial dimension (or diameter) of the first lens group 122, thereby achieving the effect of reducing the height of the periscope type photographing module 10, so as to satisfy the trend of the current light and slim development of electronic equipment.
Notably, as shown in fig. 4, it is found through optical studies that the first lens group 122 of the periscopic lens 12 has an effective optical area 1221 and a non-effective optical area 1222, wherein the effective optical area 1221 is located at a middle portion of the first lens group 122, the non-effective optical area 1222 is located at an outside of the first lens group 122, and the non-effective optical area 1222 is arranged around the effective optical area 1221, that is, the non-effective optical area 1222 is located around the effective optical area 1221, and the effective optical area 1221 of the first lens group 122 corresponds to the light channel 1211 of the lens barrel 121, such that the effective optical area 1221 of the first lens group 122 serves to collect the imaging light passing through the effective optical area 1221 of the first lens group 122, and the non-effective optical area 1222 of the first lens group 122 serves to contact the lens barrel 121 while fixedly mounting the first lens group 122.
It should be appreciated that since the inactive optical area 1222 of the first lens group 122 mainly functions to provide a contact surface corresponding to the lens barrel 121 to ensure that the active optical area 1221 of the first lens group 122 is not contacted or blocked by the lens barrel 121, a portion of the inactive optical area 1222 of the first lens group 122 may be exposed outside the lens barrel 121 to form an exposed portion of the first lens group 122, and another portion of the inactive optical area 1222 of the first lens group 122 may be covered by the lens barrel 121, thereby not affecting the converging effect of the first lens group 122 on the imaging light while ensuring that the first lens group 122 is fixedly mounted to the lens barrel 121.
Preferably, as shown in fig. 4 and 5, the lens barrel 121 of the periscopic lens 12 is further provided with at least one side opening 1210 located at the first end 1212 of the lens barrel 121, wherein the at least one side opening 1210 is located in a height direction of the lens barrel 121 and communicates with the light channel 1211 of the lens barrel 121, wherein at least a portion of the non-effective optical area 1222 of the first lens group 121 can protrude from the corresponding at least one side opening 1210 such that the at least a portion of the non-effective optical area 1222 of the first lens group 121 is exposed outside the lens barrel 121 in the height direction of the lens barrel 121, thereby reducing the height of the periscopic lens 12.
Illustratively, as shown in fig. 4 and 5, the at least one side opening 1210 of the barrel 121 of the periscope lens 12 includes an upper side opening 1214 and a lower side opening 1215, wherein the upper side opening 1214 and the lower side opening 1215 are respectively communicated with the light passage 1211, and when the first lens group 122 is mounted to the light passage 1211 of the barrel 121, an upper side portion 12221 of the non-effective optical area 1222 of the first lens group 122 protrudes from the upper side opening 1214 of the barrel 121 so that the upper side portion 1222 of the non-effective optical area 1222 of the first lens group 122 is exposed outside the barrel 121 to form an upper exposed portion; a lower portion 12222 of the inactive optical area 1222 of the first lens group 122 protrudes from the lower opening 1215 of the lens barrel 121 such that the lower portion 12222 of the inactive optical area 1222 of the first lens group 122 is exposed outside the lens barrel 121 to form a lower exposed portion, so that the height of the periscope lens 12 is equal to the dimension of the first lens group 122 in the up-down direction (i.e., the radial dimension or diameter of the first lens group 122) to reduce the height of the periscope image pickup module 10.
It should be appreciated that, since the periscope type lens 12 of the periscope type camera module 10 according to the first preferred embodiment of the present invention is reduced in thickness of the side walls of the two layers of the lens barrel 121 in the height direction compared to the existing periscope type camera module, even if all lenses of the periscope type lens 12 of the periscope type camera module 10 are identical to all lenses of the existing periscope type camera module's optical lenses, the periscope type camera module 10 will have a smaller height than the existing periscope type camera module, thereby making the periscope type camera module 10 according to the first preferred embodiment of the present invention particularly suitable for the light and thin development trend of the current electronic devices.
As shown in fig. 6 and 7, the present invention further provides a first variant of the periscopic lens 12 according to the first preferred embodiment of the present invention, wherein the periscopic lens 12 of the periscopic camera module 10 further comprises an opaque layer 124, and the opaque layer 124 is disposed to cover a portion of the non-effective optical area 1222 of the first lens group 122 corresponding to the at least one side opening 1210 of the lens barrel 121, so as to prevent stray light from entering the effective optical area 1221 of the first lens group 122 from the non-effective optical area 1222 of the first lens group 122, and at the same time, avoid light leakage caused by the imaging light exiting from the non-effective optical area 1222 of the first lens group 122, thereby improving the photographing quality of the periscopic camera module 10. It should be understood that the thickness of the opaque layer 124 is smaller than the thickness of the side wall of the lens barrel 121, so as to ensure that the height of the periscope type camera module 10 according to the first modified embodiment of the present invention is smaller than that of the existing periscope type camera module. More preferably, the thickness of the opaque layer 124 is thin to prevent the height of the periscope type camera module 10 from being greatly increased due to the opaque layer 124.
Illustratively, the opaque layer 124 is disposed to cover the upper portion 12221 and the lower portion 12222 of the inactive optical area 1222 of the first lens group 122, so as to prevent stray light from entering the active optical area 1221 of the first lens group 122 from the upper portion 12221 and the lower portion 12222 of the inactive optical area 1222 of the first lens group 122, and at the same time, to prevent problems caused by the imaging light being emitted from the upper portion 12221 and the lower portion 12222 of the inactive optical area 1222 of the first lens group 122, thereby improving the photographing quality of the periscopic camera module 10.
In particular, the opaque layer 124 may be, but is not limited to, made of an opaque material such as black glue, black paint, black pigment, black paint, etc. in a coating manner to cover the upper portion 12221 and the lower portion 12222 of the inactive optical region 1222 of the first lens group 122. It should be appreciated that since the opaque layer 124 is formed in a coated manner, the opaque layer 124 can have an extremely thin thickness, so that the influence of the opaque layer 124 on the height of the periscope type camera module 10 can be minimized.
Illustratively, as shown in fig. 6, after the first lens group 122 is mounted to the lens barrel 121, a layer of black glue is applied to the upper and lower portions 12221 and 12222 of the inactive optical area 1222 of the first lens group 122 to form the light-impermeable layer 124 covering the upper and lower portions 12221 and 12222 of the inactive optical area 1222 of the first lens group 122 after the black glue is cured. In other words, after the first lens group 122 is mounted to the lens barrel 121, only a layer of black glue is applied to the exposed portion of the inactive optical area 1222 of the first lens group 122, so that the opaque layer 124 covering the upper portion 12221 and the lower portion 12222 of the inactive optical area 1222 of the first lens group 122 can be formed after the black glue is cured, thereby simplifying the complexity of the whole application process and reducing the difficulty of manufacturing the opaque layer 124.
In addition, as illustrated in fig. 7, a layer of black glue may be applied to the upper and lower portions 12221 and 12222 of the inactive optical region 1222 of the first lens group 122 before the first lens group 122 is mounted to the lens barrel 121, to form the light-blocking layer 124 after the black glue is cured, wherein the light-blocking layer 124 covers the upper and lower portions 12221 and 12222 of the inactive optical region 1222 of the first lens group 122; then, the first lens group 122 is mounted to the lens barrel 121 correspondingly, and the upper and lower side portions 12221, 12222 of the inactive optical region 1222 of the first lens group 122 are secured to correspond to the upper and lower side openings 1214, 1215 of the lens barrel 121, respectively.
Fig. 8 shows a second variant of the periscopic lens 12 according to the first preferred embodiment of the present invention, wherein the opaque layer 124 is disposed to cover all the portions of the inactive optical region 1222 of the first lens group 122, so as to prevent stray light from entering the active optical region 1221 of the first lens group 122 through any position of the inactive optical region 1222 of the first lens group 122, or light leakage problem caused by the imaging light exiting through any position of the inactive optical region 1222 of the first lens group 122. It should be appreciated that since the opaque layer 124 covers all portions of the inactive optical region 1222 of the first lens group 122, an opaque material needs to be applied to the inactive optical region 1222 of the first lens group 122 before the first lens group 122 is mounted to the lens barrel 121, so that the opaque layer 124 is formed on the inactive optical region 1222 of the first lens group 122.
Illustratively, as shown in fig. 8, a black glue is applied to all portions of the inactive optical area 1222 of the first lens group 122 before the first lens group 122 is mounted to the lens barrel 121, so as to form the opaque layer 124 covering all portions of the inactive optical area 1222 of the first lens group 122 after the black glue is cured.
The present invention further provides a method for manufacturing the periscope lens 12 according to the first preferred embodiment of the present invention. As shown in fig. 9, the manufacturing method of the periscope 12 includes the steps of:
s1: a second lens group 123 is installed in an optical channel 1211 of a lens barrel 121, and the second lens group 123 is located at a second end 1213 of the lens barrel 121; and
s2: a first lens group 122 is mounted on the optical channel 1211 of the lens barrel 121, and the first lens group 122 is located at a first end 1212 of the lens barrel 121, wherein a radial dimension of the first lens group 122 is larger than a radial dimension of the second lens group 123, and a portion of an inactive optical area 1222 of the first lens group 122 is exposed to the lens barrel 121 to form an exposed portion of the inactive optical area 1222 of the first lens group 122.
Further, the manufacturing method of the periscope 12 further comprises the following steps:
s3: an opaque layer 124 is disposed on the inactive optical area 1222 of the first lens group 122 to cover the exposed portion of the inactive optical area 1222 of the first lens group 122 by the opaque layer 124.
Notably, in said step S3: a black glue is applied to the exposed portion of the inactive optical area 1222 of the first lens group 122 to form the opaque layer 124 covering the exposed portion of the inactive optical area 1222 of the first lens group 122 after the black glue is cured.
It should be understood that in the manufacturing method of the periscope lens 12, the sequence among the step S1, the step S2 and the step S3 is not limited, for example, the step S2 may be performed first, and then the step S1 and the step S3 may be performed; the step S3 may be performed first, and then the step S1 and the step S2 may be performed.
In addition, in the first preferred embodiment of the present invention, as shown in fig. 10, the method for manufacturing the periscope type camera module 10 includes the steps of:
(A) Correspondingly, a light steering component 13 is arranged on a photosensitive path of a photosensitive component 11; and
(B) A periscope lens 12 is correspondingly disposed on the photosensitive path of the photosensitive assembly 11, and the periscope lens 12 is disposed between the light steering assembly 13 and the photosensitive assembly 11, wherein a first lens group 122 of the periscope lens 12 is partially covered by a lens barrel 121 of the periscope lens 12.
It should be understood that in the first preferred embodiment of the present invention, the order of the steps (a) and (B) is not limited, and for example, the step (B) may be performed first and then the step (a) may be performed.
It should be noted that, since the inactive optical area 1222 of the first lens group 122 of the periscope lens 12 has a smaller influence on the working effect of the first lens group 122, the present invention further provides a periscope lens 12A according to a second preferred embodiment of the present invention as shown in fig. 11 and 12. The periscope lens 12A according to the second preferred embodiment of the present invention is different from the first preferred embodiment of the present invention in that: the dimension of the first lens group 122A of the periscope lens 12A in the height direction of the lens barrel 121 is smaller than the radial dimension of the first lens group 122A, in other words, the dimension of the first lens group 122A in the height direction of the lens barrel 121 is smaller than the diameter of the first lens group 122A (i.e., the diameter of the first lens group 122) to further reduce the height of the periscope lens 12A, thereby further reducing the overall height of the periscope image capturing module.
Preferably, as shown in fig. 11 and 12, the first lens group 122A of the periscopic lens 12A is provided with the effective optical area 1221 and a non-effective optical area 1222A, wherein the non-effective optical area 1222A is located around the effective optical area 1221, and the non-effective optical area 1222A is provided with at least one edge plane 12220A, wherein each of the edge planes 12220A corresponds to the corresponding side opening 1210 of the lens barrel 121 when the first lens group 122A is mounted to the lens barrel 121, such that a dimension of the first lens group 122A in a height direction of the lens barrel 121 is smaller than a radial dimension of the first lens group 122A, thereby reducing a height of the periscopic lens 12A.
Illustratively, the at least one edge plane 12220A of the inactive optical area 1222A of the first lens group 122A includes an upper edge plane 12223A and a lower edge plane 12224A, wherein the upper edge plane 12223A and the lower edge plane 12224A are parallel to each other, and a distance between the upper edge plane 12223A and the lower edge plane 12224A is smaller than a dimension of the first lens group 122A in a non-up-down direction (i.e., a non-height direction), wherein the upper edge plane 12223A and the lower edge plane 12224A of the inactive optical area 1222A correspond to the upper opening 1214 and the lower opening 1215 of the lens barrel 121, respectively, to reduce a height of the periscopic lens 12A, thereby reducing a height of the periscopic camera module when the first lens group 122A is mounted to the lens barrel 121.
Preferably, as shown in fig. 11, the distance between the upper edge plane 12223A and the lower edge plane 12224A of the inactive optical region 1222A of the first lens group 122A is not greater than the height of the lens barrel 121A to ensure that the upper edge plane 12223A and the lower edge plane 12224A of the first lens group 122A do not protrude from the upper side opening 1214 and the lower side opening 1215 of the lens barrel 121, respectively, in order to prevent an increase in the height of the periscopic lens 12A.
More preferably, as shown in fig. 11, a distance between the upper edge plane 12223A and the lower edge plane 12224A of the inactive optical region 1222A of the first lens group 122A is equal to a height of the lens barrel 121A, so that the upper edge plane 12223A and the lower edge plane 12224A of the first lens group 122A are aligned with outer sidewalls of the lens barrel 121, respectively, when the first lens group 12 is mounted to the lens barrel 121.
It should be noted that, in the second preferred embodiment of the present invention, as shown in fig. 12, the first lens group 122A may be manufactured by integral molding, die molding or injection molding, so that the first lens group 122A is manufactured to have a dimension of the first lens group 122A in the height direction smaller than a radial dimension of the first lens group 122A. For example, when the first lens group 122A is formed by molding, the upper edge plane 12223A and the lower edge plane 12224A are parallel to each other, and the distance between the upper edge plane 12223A and the lower edge plane 12224A is made smaller than the radial dimension of the first lens group 122A, so as to simplify the manufacturing process of the first lens group 122A. It should be understood that the first lens group 122A may be made of a transparent material such as plastic, glass, resin, etc., and is not limited in the second preferred embodiment of the present invention.
It should be noted that, as shown in fig. 13, in the first preferred embodiment of the present invention, since the first lens group 122 of the periscopic camera module 10 generally has a circular cross section, that is, the radial dimensions of the first lens group 122 are equal in all directions, that is, the upper portion 12221 and the lower portion 12222 of the inactive optical area 1222 of the first lens group 122 are arc-shaped structures, in some other embodiments of the present invention, the upper portion 12221 and the lower portion 12222 of the inactive optical area 1222 of the first lens group 122 may be cut off by cutting, so as to form the upper edge plane 12223A and the lower edge plane 12224A of the inactive optical area 1222A of the first lens group 122A.
Illustratively, as shown in fig. 13, before the first lens group 122 is mounted to the lens barrel 121, the upper side portion 12221 and the lower side portion 12222 of the non-effective optical area 1222 of the first lens group 122 are cut off to form the first lens group 122A having the upper edge plane 12223A and the lower edge plane 12224A, and then the first lens group 122A is mounted to the lens barrel 121 to make the periscope lens 12A such that the periscope lens 12A is smaller in height than the radial dimension of the first lens group 122, and therefore, the periscope camera module according to the second preferred embodiment of the present invention can be smaller in height than the periscope camera module 10 according to the first preferred embodiment of the present invention. In other words, since the exposed portion of the inactive optical region 1222 of the first lens group 122 according to the first preferred embodiment of the present invention is cut away to reduce the size of the first lens group 122 in the up-down direction (i.e., the height direction), the height of the periscope lens 12 is further reduced to achieve the effect of further reducing the height of the periscope image capturing module 10.
It should be appreciated that in another embodiment of the present invention, the bare portion of the inactive optical region 1222 of the first lens group 122 may be cut along the outer side wall of the lens barrel 121 after the first lens group 122 is mounted to the lens barrel 121, so that it is possible to ensure that the upper edge plane 12223A and the lower edge plane 12224A of the first lens group 122A are aligned with the outer side wall of the lens barrel 121, respectively, while ensuring that the inactive optical region 1222 of the first lens group 122 does not protrude out of the lens barrel 121, to minimize the influence on the operation of the active optical region 1221 of the first lens group 122 due to the excessive cutting of the inactive optical region 1222 of the first lens group 122.
It is noted that, in the second preferred embodiment of the present invention, since the upper edge plane 12223A and the lower edge plane 12224A of the non-effective optical area 1222A of the first lens group 122A are not covered by the lens barrel 121, in order to eliminate the interference of stray light to the first lens group 122A or to prevent the problem of light leakage of the first lens group 122A, as shown in fig. 14, the present invention further provides a variant of the periscopic lens 12A according to the second preferred embodiment of the present invention, wherein the periscopic lens 12A also includes the light-impermeable layer 124, wherein the light-impermeable layer 124 is disposed to cover the upper edge plane 12223A and the lower edge plane 12224A of the non-effective optical area 122A of the first lens group 122A, to prevent stray light from exiting the upper edge plane 23A and the lower edge plane 12224A of the non-effective optical area 122A of the first lens group 122A, and to thereby further improve the quality of the periscopic lens group 1222A and the lower edge plane 12224A of the non-effective optical area 122A of the first lens group 122A, and further to thereby prevent the problem of light from exiting the periscopic lens group 122A from exiting the lower edge plane 1222A of the non-effective optical area 122A.
It should be noted that, in the second preferred embodiment of the present invention, except for the above-mentioned structure, other structures of the periscope type camera module are the same as those of the periscope type camera module 10 according to the first preferred embodiment of the present invention, and the periscope type camera module also has various modification embodiments similar to or the same as those of the periscope type camera module 10 of the first preferred embodiment, which are not repeated herein.
Since the first lens group 122 of the periscope type camera module 10 according to the first preferred embodiment of the present invention has a generally circular cross section, and a portion of the inactive optical area 1222 of the first lens group 122 is not covered by the lens barrel 121, a contact area between the first lens group 122 and the lens barrel 121 becomes small, which easily causes the first lens group 122 mounted on the lens barrel 121 to loosen or rotate around the optical axis of the first lens group 122, thereby affecting the normal operation of the first lens group 122. Particularly, when the opaque layer 124 covers only a portion of the non-effective optical area 1222 of the first lens group 122, the non-effective optical area 1222 not covered by the opaque layer 124 is exposed outside the lens barrel 121 once the first lens group 122 rotates, thereby increasing the influence on the effective optical area 1221 of the first lens group 122. Therefore, the present invention further provides a periscope type camera module according to a third preferred embodiment of the present invention.
Referring to fig. 15 and 16 of the drawings, the periscope 12B according to the third preferred embodiment of the present invention is illustrated.

Preferably, as shown in fig. 15 and 16, each of the stopper elements 126B is provided at a left side portion 12225 or a right side portion 12226 of the inactive optical region 1222 of the first lens group 122B, and accordingly, each of the stopper grooves 127B is provided at a left side or a right side of the first end 1212 of the lens barrel 121B, so that when the first lens group 122B is mounted to the lens barrel 121B, the stopper elements 126B are coupled with the stopper grooves 127B of the corresponding lens barrel 121B to ensure that the upper and lower side portions 12221, 12222 of the inactive optical region 1222 of the first lens group 122B correspond to the upper and lower side openings 1214, 1215 of the lens barrel 121, respectively. At the same time, the height of the periscope 12B can be prevented from being increased by providing the stopper 126B or the stopper groove 127B on the periscope 12B.
In the third preferred embodiment of the present invention, as shown in fig. 15 and 16, the first lens group 122B illustratively includes two limiting elements 126B, and the lens barrel 121B also includes two limiting grooves 127B, wherein the two limiting elements 126B respectively protrude radially from the left side portion 12225 and the right side portion 12226 of the inactive optical area 1222 of the first lens group 122B to form two protrusions in the inactive optical area 1222 of the first lens group 122B, and the two limiting grooves 127B respectively recess inwardly from the left side and the right side of the first end 1212 of the lens barrel 121B to form two notches matching with the corresponding limiting elements 126B at the first end 1212 of the lens barrel 121B, such that when the first lens group 122B is mounted to the lens barrel 121B, the limiting elements 126B respectively insert into the corresponding limiting grooves 127B to facilitate the engagement of the limiting elements 126B with the corresponding limiting grooves 1212 at the first end 121B.
Preferably, as shown in fig. 16, the limiting element 126B integrally and prominently extends from the inactive optical area 1222 of the first lens group 122B to form the first lens group 122B having an integral structure. It should be appreciated that in some other embodiments of the present invention, the stop element 126B may also be fixedly disposed to the inactive optical region 1222 of the first lens group 122B by gluing, welding, or the like.
It should be noted that, in the third preferred embodiment of the present invention, since the limiting element 126B is integrally formed in the non-effective optical area 1222 of the first lens group 122B, that is, the limiting element 126B and the non-effective optical area 1222 of the first lens group 122B are made of the same material, that is, the limiting element 126B is also made of a light-transmitting material, when the first lens group 122B is mounted on the lens barrel 121B, the limiting element 126B is located in the limiting groove 127B of the lens barrel 121B (i.e. the notch of the lens barrel 121B), a problem that some stray light may be incident into the effective optical area 1221 of the first lens group 122B through the limiting element 126B, or a problem that light leakage occurs due to the imaging light incident into the first lens group 122B through the limiting element 126B is easy to occur.
Therefore, in order to solve the above-mentioned problems, as shown in fig. 17, the present invention further provides a first variant of the periscopic lens 12B according to the third preferred embodiment of the present invention, wherein the periscopic lens 12B further comprises the opaque layer 124, and the opaque layer 124 is configured to cover the limiting element 126B, so as to prevent stray light from entering the effective optical area 1221 of the first lens group 122B from the limiting element 126B, and at the same time, avoid the problem of light leakage caused by the light emitted from the limiting element 126B, thereby improving the shooting quality of the periscopic camera module 10.
Preferably, as shown in fig. 17, the opaque layer 124 is disposed to cover the limiting element 126B and the upper portion 12221 and the lower portion 12222 of the inactive optical region 1222B of the first lens group 122B at the same time, so as to minimize the interference of stray light or the problem of light leakage, thereby improving the photographing quality of the periscope type photographing module 10.

As shown in fig. 18 and 19, the periscope lens 12B includes two limit elements 126B and two limit grooves 127B, wherein the limit grooves 127B are respectively recessed inward from the left side portion 12225 and the right side portion 12226 of the inactive optical area 1222 of the first lens group 122B to form two notches in the inactive optical area 1222 of the first lens group 122B, and the limit elements 126B are respectively protruded from left and right sides of the first end 1212 of the lens barrel 121B toward the light channel 1211 to form two protrusions matching with the corresponding limit grooves 127B in the light channel 1211 of the lens barrel 121B, such that when the first lens group 122B is mounted to the lens barrel 121B, the limit elements 126B are respectively inserted into the corresponding limit grooves 127B to engage the limit elements 126B with the corresponding limit grooves 127B, so as to facilitate fixing the first lens group 122B to the first end 121B.
