Description

Periscopic lens, periscopic camera module, manufacturing method of periscopic camera module, periscopic array module and electronic equipment Technical Field

The present invention relates to the field of camera modules, and in particular, to a periscopic lens, a periscopic camera module, a manufacturing method thereof, a periscopic array module, and an electronic device.

Background

With the progress of the science and technology and the development of economy, people have higher and higher requirements on the camera shooting function of portable electronic equipment (such as tablet computers, ipads, smart phones and the like), and not only the camera shooting module configured for the electronic equipment is required to realize background blurring and night shooting clarity, but also the camera shooting module configured for the electronic equipment is required to realize optical zooming. The periscopic array camera module is more and more popular and valued by people as a camera module with stronger optical zoom capability.

Currently, the periscopic array module is usually composed of a periscopic telephoto camera module and a vertical wide-angle camera module. The periscopic long-focus camera shooting module reflects or refracts light rays entering the end part of the camera shooting module in order to change the direction of the light rays and then enters the interior of the camera shooting module in a mode of adding a prism at the front end of the conventional long-focus 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 periscopic long-focus camera module is improved by increasing the module focal length of the periscopic long-focus camera module, the length of the periscopic long-focus camera module is lengthened, the height of the periscopic long-focus camera module cannot be increased, and correspondingly, the height of the periscopic long-focus camera module cannot be increased, so that the thickness of the electronic equipment provided with the periscopic long-focus camera module can be prevented from being increased.

However, in order to comply with the trend of light and thin electronic devices, the height of the periscopic array module, i.e. the periscopic telephoto camera module, needs to be further reduced. In the design of the existing periscopic long-focus camera module, the optical lens of the existing periscopic long-focus camera module comprises a group of lenses and a lens barrel, wherein the lens barrel covers the group of lenses, and 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 periscopic long-focus camera module is inevitably larger than that of the first lens, therefore, the height of the existing periscopic long-focus camera module cannot be further reduced, and the existing periscopic long-focus camera module cannot meet the requirement of the current electronic equipment on the development of light and thin, and the application and popularization of the periscopic long-focus camera module in various electronic equipment are greatly limited.

In the description of the present invention, it should be noted that, unless explicitly stated or limited otherwise, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In this specification, the schematic representations of the terms used above are not necessarily intended to refer 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, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

Referring to fig. 1 to 10 of the drawings, a periscopic array module according to a first preferred embodiment of the present invention is illustrated. As shown in fig. 1, the periscopic array module 1 includes at least one periscopic camera module 10 and at least one upright camera module 20, wherein the periscopic camera module 10 and the upright camera module 20 are combined to form the periscopic array module 1 with different assembly layouts, and the periscopic array module 1 has an optical zoom function.

It should be noted that although the periscopic array module 1 shown in fig. 1 to 10 and the following description are only provided with one periscopic camera module 10 and one upright camera module 20 as an example to illustrate the features and advantages of the periscopic array module 1 of the present invention, it should be understood by those skilled in the art that the periscopic array module 1 shown in fig. 1 to 10 and the following description is only an example and is not to be construed as a limitation to the scope and content of the present invention, for example, in other examples of the periscopic array module, the number of the periscopic array modules 10 and the upright camera modules 20 may be more than one to improve the shooting effect of the periscopic 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 that of the periscopic camera module 10, that is, the Field of View (FOV) of the upright camera module 20 is larger than that of the periscopic camera module 10. In other words, in the present invention, the vertical camera module 20 is configured as a wide-angle camera module, the periscopic camera module 10 is configured as a long-focus camera module, and during the shooting process using the periscopic array module, the view range of the vertical camera module 20 is wider and wider, but it is difficult to shoot the details of the distant objects, and the view range of the periscopic camera module 10 is narrower, but it is possible to shoot the objects that are relatively farther away, so that the function of "optical zooming" is realized through the complementary matching of the vertical camera module 20 and the periscopic camera module 10. It should be understood that the type of the upright camera module 20 in the present invention is not limited, for example, the upright camera module 20 may be a known camera module such as a wide-angle camera module, a standard camera module, or a telephoto camera module, and the description thereof is omitted here.

According to the first preferred embodiment of the present invention, as shown in fig. 1, the periscopic camera module 10 includes a photosensitive component 11, a periscopic lens 12 and a light turning component 13, wherein the periscopic lens 12 and the light turning component 13 are both held in the photosensitive path of the photosensitive component 11, and the periscopic lens 12 is located between the photosensitive component 11 and the light turning component 13. The light steering assembly 13 can change the direction of an imaging light ray entering the light steering assembly 13, and the steered imaging light ray can firstly pass through the periscopic lens 12 along the photosensitive path of the photosensitive assembly 11 and then be received by the photosensitive assembly 11 for imaging, that is, the light steering assembly 13 can make the imaging light ray pass through the periscopic lens 12 after being steered so as to be received by the photosensitive assembly 11 for imaging. It should be understood that the imaging light can be implemented as the ambient light reflected by a space object, and can also be implemented as the light emitted by the space object itself, and the type of the imaging light is not limited in the present invention as long as the imaging light can be received by the photosensitive module 11 to form an image.

Preferably, as shown in fig. 1-3, the light diverting assembly 13 is capable of diverting light rays by 90 degrees, so that the light ray perpendicular to the light sensing path of the light sensing component 11 is converted by the light turning component 13 to be parallel to the light sensing path of the light sensing component 11, so that when the periscopic array module 1 is mounted to an electronic equipment body 500 to be assembled into an electronic equipment, the upright camera module 20 is mounted to the electronic apparatus body 500 in a "vertical" mounting manner, the periscopic camera module 10 is mounted to the electronic device body 500 in a "lying" manner, the height of the periscopic array module 1 is reduced, and the periscopic array module 1 is prevented from being larger than the height of the electronic device body 500 (i.e. the thickness of the electronic device body 500), so as to meet the trend of thinning and lightening of the electronic device.

For example, as shown in fig. 2A, after the periscopic array module 1 is assembled to an electronic device body 500 to assemble an electronic device, the upright camera module 20 is disposed along the height direction of the electronic device body 500, and the photosensitive component 11, the periscopic lens 12 and the light steering component 13 of the periscopic camera module 10 are respectively disposed along the width direction of the electronic device body 500, so that the optical axis direction of the periscopic lens 12 is parallel to the width direction of the electronic device body 500, thereby preventing the end surface of the periscopic lens 12 from protruding out of the front surface or the rear surface of the electronic device body 500 due to the overlong length of the periscopic lens 12 or increasing 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 by the height of the periscopic lens 10, regardless of the length or width of the periscopic lens 10, so that the periscopic camera module 10 of the present invention is particularly suitable for the long-focus periscopic lens 12.

As shown in fig. 2B, after the periscopic array module 1 is assembled to an electronic device body 500 to assemble an electronic device, the upright camera module 20 is disposed along the height direction of the electronic device body 500, and the photosensitive component 11, the periscopic lens 12 and the light steering component 13 of the periscopic camera module 10 are respectively disposed along the length direction of the electronic device body 500, so that the optical axis direction of the periscopic lens 12 is parallel to the length direction of the electronic device body 500, thereby preventing the end surface of the periscopic lens 12 from protruding out of the front surface or the rear surface of the electronic device body 500 due to the overlong length of the periscopic lens 12 or increasing 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 by the height of the periscopic lens 10, regardless of the length or width of the periscopic lens 10, so that the periscopic camera module 10 of the present invention is particularly suitable for the long-focus periscopic lens 12.

It should be noted that although the features and advantages of the periscopic array module 1 of the present invention are described in fig. 2A and 2B of the drawings by taking the electronic device body 500 as a smart phone body as an example, those skilled in the art should understand that the smart phone body in fig. 2A and 2B is only 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, tablet, notebook, etc.

However, as the electronic device is getting thinner and lighter, the height of the periscopic camera module 10 still becomes a great obstacle to the reduction of the height (i.e. thickness) of the electronic device, so that how to reduce the height of the periscopic camera module 10 becomes a problem to be solved urgently. It should be noted that, since the height of the periscopic lens 12 directly determines the height of the periscopic camera module 10, in the first preferred embodiment of the present invention, the height of the periscopic lens 12 is reduced by designing the structure of the periscopic lens 12, so as to achieve the effect of reducing the height of the periscopic camera module 10.

Specifically, as shown in fig. 3 to 5, the periscopic lens 12 of the periscopic camera module 10 includes a lens barrel 121, a first lens group 122 and a second lens group 123, and a radial dimension of the first lens group 122 is greater than a 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 both located in a photosensitive path of the photosensitive component 11, wherein an outer periphery of the first lens group 122 is partially covered by the lens barrel 121, and an outer periphery of the second lens group 123 is completely covered by the lens barrel 121, so that a height of the periscopic lens 12 is not greater than a radial dimension of the first lens group 122.

It should be noted that although the first lens group 122 including one lens and the second lens group 123 including four lenses are taken as examples in fig. 1 to 10 and the following description to illustrate the features and advantages of the periscopic camera module 10 of the present invention, it can be understood by those skilled in the art that the periscopic camera module 10 disclosed in fig. 1 to 10 and the following description is only an example and does not limit the content and scope of the present invention, for example, in other examples of the periscopic 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 only include a convex lens, may only include a concave lens, and may also include both a convex lens and a concave lens to achieve the light effect required by 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 a light sensing path of the light sensing component 11 to allow the diverted imaging light to pass through the lens barrel 121 along the light channel 1211, and the first lens group 122 and the second lens group 123 are coaxially mounted on the light channel 1211 of the lens barrel 121, so that the first lens group 122 and the second lens group 123 are located on the light sensing path of the light sensing component 11, so that the diverted imaging light passes through the first lens group 122 and the second lens group 123 first and then is received by the light sensing component 11 to be imaged.

It should be noted that, in all the lenses of the periscopic lens 12 of the periscopic camera module 10, the radial dimension of the lens close to the light diverting assembly 13 is generally larger than the radial dimension of the lens far from the light diverting assembly 12. Therefore, in the first preferred embodiment of the present invention, as shown in fig. 3 and fig. 5, the lens barrel 121 further has a first end 1212 adjacent to the light turning 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, 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, so that the imaging light turned by the light turning component 13 passes through the first lens group 122 first and then passes through the second lens group 123, and then is 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 turning component 13 and the photosensitive component 11, and the second lens group 123 is located between the first lens group 122 and the photosensitive component 123, so that the imaging light turned by the light turning component 13 passes through the first lens group 122, then passes through the second lens group 123, and finally is received by the photosensitive component 11 for imaging.

It should be noted that, in the existing periscopic camera module, since the lens barrel of the optical lens of the existing periscopic camera module completely covers the outer peripheries of all the lenses and the lens barrel has a corresponding thickness, the height of the optical lens of the existing periscopic camera module is inevitably greater than the radial dimension (or diameter) of all the lenses.

However, in the periscopic camera module 10 according to the first preferred embodiment of the present invention, as shown in fig. 5, the lens barrel 121 of the periscopic lens 12 of the periscopic camera module 10 partially covers the outer periphery 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 periscopic 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 periscopic camera module 10, so as to satisfy the trend of light and thin electronic devices.

It is noted that, 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 in the middle of the first lens group 122, the non-effective optical area 1222 is located outside 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 passage 1211 of the lens barrel 121, such that the effective optical area 1221 of the first lens group 122 is used for converging 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 is used for contacting the lens barrel 121 to make the first lens group 121 contact A lens group 122 is fixedly mounted to the barrel 121.

It should be understood that, since the inactive optical area 1222 of the first lens group 122 mainly serves 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 is covered by the lens barrel 121, so as to ensure that the first lens group 122 is fixedly mounted to the lens barrel 121, and at the same time, the converging effect of the first lens group 122 on the imaging light rays is not affected.

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 is communicated with the light passage 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, so 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 lens barrel 121 of the periscopic 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 optical channel 1211, and when the first lens group 122 is mounted on the optical channel 1211 of the lens 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 lens 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 lens barrel 121 to form an upper exposed portion; a lower side portion 12222 of the non-effective optical area 1222 of the first lens group 122 protrudes from the lower side opening 1215 of the lens barrel 121, so that the lower side portion 12222 of the non-effective optical area 1222 of the first lens group 122 is exposed outside the lens barrel 121 to form a lower exposed portion, thereby making the height of the periscopic lens 12 equal to the size of the first lens group 122 in the up-down direction (i.e., the radial size or diameter of the first lens group 122) to reduce the height of the periscopic camera module 10.

It should be understood that, since the periscopic lens 12 of the periscopic camera module 10 according to the first preferred embodiment of the present invention is reduced in thickness of the side walls of the lens barrel 121 in the height direction compared to the existing periscopic camera module, even if all the lenses of the periscopic lens 12 of the periscopic camera module 10 are identical to all the lenses of the optical lens of the existing periscopic camera module, the height of the periscopic camera module 10 will be smaller than that of the existing periscopic camera module, so that the periscopic camera module 10 according to the first preferred embodiment of the present invention is particularly suitable for the trend of thinning and developing the electronic devices of the present invention.

As shown in fig. 6 and 7, the present invention further provides a first modified embodiment of the periscopic lens 12 according to the first preferred embodiment of the present invention, wherein the periscopic lens 12 of the periscopic module 10 further includes a light-impermeable layer 124, wherein the light-impermeable 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 being emitted from the non-effective optical area 1222 of the first lens group 122 into the effective optical area 1221 of the first lens group 122, and at the same time, to prevent the imaging light from being emitted from the non-effective optical area 1222 of the first lens group 122 to cause light leakage, thereby improving the shooting quality of the periscopic module 10. It should be understood that the thickness of the opaque layer 124 is smaller than that of the sidewall of the lens barrel 121 to ensure that the height of the periscopic camera module 10 according to the first modified embodiment of the present invention is smaller than that of the existing periscopic camera module. More preferably, the opaque layer 124 is thin to prevent the height of the periscopic camera module 10 from being greatly increased due to the presence of the opaque layer 124.

Illustratively, the light-impermeable layer 124 is disposed to cover the upper portion 12221 and the lower portion 12222 of the ineffective optical area 1222 of the first lens group 122, so as to prevent stray light from entering the effective optical area 1221 of the first lens group 122 from the upper portion 12221 and the lower portion 12222 of the ineffective optical area 1222 of the first lens group 122, and at the same time, to prevent the imaging light from exiting the upper portion 12221 and the lower portion 12222 of the ineffective optical area 1222 of the first lens group 122 and causing a problem of light leakage, thereby improving the photographing quality of the periscopic camera module 10.

Specifically, the opaque layer 124 may be made of, but not limited to, an opaque material such as black glue, black paint, black pigment, black lacquer, etc. in a coating manner to cover the upper portion 12221 and the lower portion 12222 of the non-effective optical area 1222 of the first lens group 122. It should be understood that since the opaque layer 124 is formed in a coating 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 eliminated to the maximum extent.

Exemplarily, 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 portion 12221 and the lower portion 12222 of the non-effective optical area 1222 of the first lens group 122 to form the opaque layer 124 covering the upper portion 12221 and the lower portion 12222 of the non-effective 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 one layer of black glue needs to be applied to the exposed portion of the non-effective 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 non-effective 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 in manufacturing the opaque layer 124.

In addition, as shown in fig. 7, for example, before the first lens group 122 is mounted to the lens barrel 121, a layer of black glue may be applied to the upper portion 12221 and the lower portion 12222 of the inactive optical area 1222 of the first lens group 122 to form the opaque layer 124 after the black glue is cured, wherein the opaque layer 124 is coated on the upper portion 12221 and the lower portion 12222 of the inactive optical area 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 non-effective optical area 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 system 12 according to the first preferred embodiment of the present invention, wherein the light-impermeable layer 124 is disposed to cover all portions 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 through any position of the inactive optical area 1222 of the first lens group 122, or the imaging light from exiting through any position of the inactive optical area 1222 of the first lens group 122 and causing light leakage. It should be understood that, since the opaque layer 124 covers all portions of the inactive optical area 1222 of the first lens group 122, an opaque material needs to be applied to 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 in the inactive optical area 1222 of the first lens group 122.

Illustratively, as shown in fig. 8, before mounting the first lens group 122 to the lens barrel 121, a black glue is applied to all portions of the inactive optical area 1222 of the first lens group 122 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.

According to the first preferred embodiment of the present invention, the present invention further provides a method for manufacturing the periscopic lens 12. As shown in fig. 9, the method for manufacturing the periscopic lens 12 includes the steps of:

s1: mounting a second lens group 123 on a light channel 1211 of a lens barrel 121, wherein 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 greater than a radial dimension of the second lens group 123, and a portion of a non-effective optical area 1222 of the first lens group 122 is exposed on the lens barrel 121 to form an exposed portion of the non-effective optical area 1222 of the first lens group 122.

Further, the method for manufacturing the periscopic lens 12 further includes the steps of:

s3: an opaque layer 124 is disposed on the non-effective optical area 1222 of the first lens group 122, such that the exposed portion of the non-effective optical area 1222 of the first lens group 122 is covered by the opaque layer 124.

Note that, in the step S3: a black glue is applied to the exposed portions of the inactive optical area 1222 of the first lens group 122 to form the opaque layer 124 covering the exposed portions 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 periscopic lens 12, the order among the step S1, the step S2 and the step S3 is not limited, for example, the step S2 may be executed first, and then the step S1 and the step S3 may be executed; it is also possible to execute the step S3 first, then execute the step S1 and the step S2, and so on.

In addition, in the first preferred embodiment of the present invention, as shown in fig. 10, the method for manufacturing the periscopic camera module 10 includes the steps of:

(A) correspondingly arranging a light steering component 13 on a photosensitive path of the photosensitive component 11; and

(B) a periscopic lens 12 is correspondingly disposed on the light sensing path of the light sensing device 11, and the periscopic lens 12 is located between the light turning device 13 and the light sensing device 11, wherein a first lens group 122 of the periscopic lens 12 is partially covered by a lens barrel 121 of the periscopic lens 12.

It should be understood that in the first preferred embodiment of the present invention, the order of the step (a) and the step (B) is not limited, for example, the step (B) may be performed first, and then the step (a) may be performed.

It should be noted that, since the non-effective optical area 1222 of the first lens group 122 of the periscopic lens 12 has less influence on the working effect of the first lens group 122, as shown in fig. 11 and 12, the invention further provides a periscopic lens 12A according to a second preferred embodiment of the invention. The periscopic lens 12A according to the second preferred embodiment of the present invention differs from the first preferred embodiment of the present invention in that: the size of the first lens group 122A of the periscopic lens 12A in the height direction of the lens barrel 121 is smaller than the radial size of the first lens group 122A, in other words, the size 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), so as to further reduce the height of the periscopic lens 12A, thereby further reducing the overall height of the periscopic camera 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 edge plane 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, so that the size of the first lens group 122A in the height direction of the lens barrel 121 is smaller than the radial size of the first lens group 122A, thereby reducing the height of the periscopic lens 12A.

Illustratively, the at least one edge plane 12220A of the non-effective 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 when the first lens group 122A is mounted to the lens barrel 121, the upper edge plane 12223A and the lower edge plane 12224A of the non-effective 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.

Preferably, as shown in fig. 11, the distance between the upper edge plane 12223A and the lower edge plane 12224A of the non-effective optical area 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 opening 1214 and the lower opening 1215 of the lens barrel 121, respectively, to increase 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 non-effective optical area 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 respectively aligned with an outer sidewall of the lens barrel 121 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 assembly 122A can be manufactured by integral molding, mold forming or injection molding, so that the first lens assembly 122A has a height dimension smaller than a radial dimension of the first lens assembly 122A after being manufactured. For example, when the first lens group 122A is formed by molding, the first lens group 122A has the upper edge plane 12223A and the lower edge plane 12224A parallel to each other, and the distance between the upper edge plane 12223A and the lower edge plane 12224A is 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 can be made of 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, since in the first preferred embodiment of the present invention, the first lens group 122 of the periscopic camera module 10 generally has a circular cross section, i.e. the radial dimension of the first lens group 122 is equal in all directions, i.e. the upper portion 12221 and the lower portion 12222 of the non-effective optical area 1222 of the first lens group 122 are both arc-shaped structures, in some other embodiments of the present invention, the upper portion 12221 and the lower portion 12222 of the non-effective optical area 1222 of the first lens group 122 can also be cut out by cutting, but not limited to, to form the upper edge plane 12223A and the lower edge plane 12224A of the non-effective optical area 1222A of the first lens group 122A.

Exemplarily, as shown in fig. 13, before mounting the first lens group 122 to the lens barrel 121, the upper side part 12221 and the lower side part 12222 of the non-effective optical area 1222 of the first lens group 122 are cut out 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 periscopic lens 12A such that the height of the periscopic lens 12A is smaller than the radial dimension of the first lens group 122, and thus the height of the periscopic camera module according to the second preferred embodiment of the present invention can be smaller than the height of the periscopic camera module 10 according to the first preferred embodiment of the present invention. In other words, since the exposed portion of the non-effective optical area 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., height direction), the height of the periscopic lens 12 is further reduced to achieve the effect of further reducing the height of the periscopic camera module 10.

It should be understood that, in another embodiment of the present invention, the bare portion of the inactive optical area 1222 of the first lens group 122 may also be cut along the outer sidewall of the lens barrel 121 after the first lens group 122 is mounted to the lens barrel 121, so as to ensure that the inactive optical area 1222 of the first lens group 122 does not protrude out of the lens barrel 121, and also ensure that the upper edge plane 12223A and the lower edge plane 12224A of the first lens group 122A are respectively aligned with the outer sidewall of the lens barrel 121, so as to minimize the influence on the operation of the active optical area 1221 of the first lens group 122 due to the excessive cutting of the inactive optical area 1222 of the first lens group 122.

It should be 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 ineffective 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 prevent the first lens group 122A from light leakage, as shown in fig. 14, the present invention further provides a modified embodiment of the periscopic lens 12A according to the second preferred embodiment of the present invention, wherein the periscopic lens 12A also includes the opaque layer 124, wherein the opaque layer 124 is disposed to cover the upper edge plane 12223A and the lower edge plane 12224A of the ineffective optical area 1222A of the first lens group 122A to prevent stray light from the upper edge plane 12223A and the lower edge plane 12224A of the ineffective optical area 1222A of the first lens group 122A The lower edge plane 12224A enters the effective optical area 1221 of the first lens group 122A, and at the same time, the imaging light can be prevented from exiting from the upper edge plane 12223A and the lower edge plane 12224A of the non-effective optical area 1222A of the first lens group 122A to cause light leakage, thereby improving the shooting quality of the periscopic camera module.

It should be noted that, in the second preferred embodiment of the present invention, except for the above-mentioned differences, other structures of the periscopic camera module are the same as the structure of the periscopic camera module 10 according to the first preferred embodiment of the present invention, and the periscopic camera module also has a modified embodiment similar to or the same as the various modified embodiments of the periscopic camera module 10 according to the first preferred embodiment, and therefore, the descriptions thereof are omitted.

Since the first lens group 122 of the periscopic camera module 10 according to the first preferred embodiment of the present invention generally has a circular cross section, and a portion of the non-effective 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 behind the lens barrel 121 to be loosened or rotated 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, once the first lens group 122 rotates, the non-effective optical area 1222 not covered by the opaque layer 124 is exposed outside the lens barrel 121, thereby increasing the influence on the effective optical area 1221 of the first lens group 122. Therefore, the present invention further provides a periscopic camera module according to a third preferred embodiment of the present invention.

Referring to fig. 15 and 16 of the drawings, the periscopic lens 12B according to the third preferred embodiment of the present invention is illustrated. The periscopic lens 12B according to the third preferred embodiment of the present invention is different from the first preferred embodiment of the present invention in that: the periscopic lens 12B further includes at least one position-limiting element 126B and at least one position-limiting groove 127B corresponding to the position-limiting element 126B, wherein each position-limiting element 126B is disposed in the non-effective optical area 1222 of the first lens group 122B, each position-limiting groove 127B is disposed at the first end 1212 of the first lens group 121B, and when the first lens group 122B is mounted at the first end 1212 of the lens barrel 121B, each position-limiting element 126B is coupled with the corresponding position-limiting groove 127B in a matching manner, so as to position-limit the first lens group 122B to be mounted on the lens barrel 121B, so as to prevent the first lens group 122B from rotating unintentionally or accidentally.

Preferably, as shown in fig. 15 and 16, each of the limiting members 126B is disposed at a left portion 12225 or a right portion 12226 of the non-effective optical area 1222 of the first lens group 122B, and each of the limiting grooves 127B is disposed at a left side or a right side of the first end 1212 of the lens barrel 121B, respectively, so that when the first lens group 122B is mounted to the lens barrel 121B, the limiting members 126B are coupled with the corresponding limiting grooves 127B of the lens barrel 121B to ensure that the upper and lower portions 12221, 12222 of the non-effective optical area 1222 of the first lens group 122B correspond to the upper and lower openings 1214, 1215 of the lens barrel 121, respectively. At the same time, it is possible to prevent the periscopic lens 12B from being increased in height by providing the limiting element 126B or the limiting groove 127B on the periscopic lens 12B.

In the third preferred embodiment of the present invention, as shown in fig. 15 and 16, for example, the first lens group 122B includes two limiting elements 126B, and the lens barrel 121B also includes two limiting grooves 127B, wherein the two limiting elements 126B respectively protrude from the left portion 12225 and the right portion 12226 of the non-effective optical area 1222 of the first lens group 122B and extend radially to form two protruding blocks in the non-effective optical area 1222 of the first lens group 122B, the two limiting grooves 127B respectively recess inwards 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 in the first end 1212 of the lens barrel 121B, so that the limiting elements 126B are respectively inserted into the corresponding limiting grooves 127B when the first lens group 122B is mounted on the lens barrel 121B, so that the limiting element 126B is engaged with the corresponding limiting groove 127B, so as to fix the first lens group 122B at the first end 1212 of the lens barrel 121B in a limiting manner.

Preferably, as shown in fig. 16, the limiting element 126B integrally and protrudingly extends from the non-effective optical area 1222 of the first lens group 122B to form the first lens group 122B having an integral structure. It should be understood that in some other embodiments of the present invention, the position-limiting element 126B can also be fixedly disposed on the non-effective optical area 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 position-limiting element 126B is integrally formed on the non-effective optical area 1222 of the first lens group 122B, that is, the stop element 126B is made of the same material as the non-effective optical area 1222 of the first lens group 122B, that is, the position limiting member 126B is also made of a light-transmitting material, and when the first lens group 122B is mounted to the lens barrel 121B, the position-limiting element 126B is located in the position-limiting groove 127B of the lens barrel 121B (i.e. the notch of the lens barrel 121B), there is a problem that some stray light will possibly be incident into the effective optical area 1221 of the first lens group 122B via the limiting element 126B, or the imaging light rays incident into the first lens group 122B are emitted through the limiting element 126B, so that the light leakage problem occurs.

As shown in fig. 18 and 19, the periscopic lens 12B includes two of the limiting elements 126B and two of the limiting grooves 127B, wherein the two limiting grooves 127B are respectively recessed from the left portion 12225 and the right portion 12226 of the non-effective optical area 1222 of the first lens group 122B to form two notches in the non-effective optical area 1222 of the first lens group 122B, the two limiting elements 126B respectively extend from the left side and the right side of the first end 1212 of the lens barrel 121B toward the optical channel 1211 to form two protrusions matching with the corresponding limiting grooves 127B in the optical channel 1211 of the lens barrel 121B, so that when the first lens group 122B is mounted to the lens barrel 121B, the limiting elements 126B are respectively inserted into the corresponding limiting grooves 127B to engage the limiting elements 126B with the corresponding limiting grooves 127B, the first lens group 122B is conveniently fixed to the first end 1212 of the lens barrel 121B in a limiting manner. Meanwhile, the light-opaque layer 124 of the periscopic lens 12B is disposed to cover the upper portion 12221 and the lower portion 12222 of the non-effective optical area 1222 of the first lens group 122B, so as to improve the photographing quality of the periscopic camera module.

It should be understood that, in the third preferred embodiment according to the present invention, in order to further reduce the height of the periscopic camera module 10B, the first lens group 122B having the upper edge plane 12223A and the lower edge plane 12224A may also be formed by using a mold forming method, or the upper portion 12221 and the lower portion 12222 of the non-effective optical area 1222 of the first lens group 122B of the periscopic lens 12B may also be cut off by using a cutting method, and the specific technical solution is the same as that in the second preferred embodiment according to the present invention, and will not be described again.
