DETAILED DESCRIPTION

[0046] The exemplary embodiments will be described in detail hereinbelow with reference to the accompanying drawings. In the following description, the same numbers refer to the same or similar elements throughout the drawings. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present disclosure. Rather, they are merely examples of structures consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0047] The technical solutions provided by the various embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0048] In the related art, the camera used in the current mobile phone is a fixed focal length lens. For example, a zoom function is achieved by using multiple fixed focus lenses such as long focal, wide angle, or ultra-wide angle lenses in combination. There is no continuous optical zoom lens like a single-lens reflex camera.

[0049] Based on this, the embodiments of the present disclosure provide a lens module. Figure 1 is a structural schematic diagram of a lens module according to an exemplary embodiment Figure 1 As shown in the figure, the lens module 10 can include: Figure 1 As shown in the figure, the lens module 10 can include:

[0050] An object plane end 11 and an image plane end 12 arranged along an optical axis direction F;

[0051] A first lens group 13 located between the object plane end 11 and the image plane end 12;

[0052] A second lens group 14 located between the first lens group 13 and the image plane end 12 and capable of moving along the optical axis direction F between the first lens group 13 and the image plane end 12 to change the focal length of the lens module 10.

[0053] In the embodiments of the present disclosure, the lens module can be an optical lens used for realizing zoom function in an electronic device; the electronic device can be a smart phone, a tablet computer, various wearable devices, a virtual reality (VR) device, a monitoring device, a vehicle-mounted device, a smart home device, or any device with a camera function.

[0054] Here, the object plane end can refer to an end of the lens module facing a photographed object, the image plane end can refer to an end of the lens module facing a camera sensor, i.e., an imaging end. The optical axis direction can refer to a central axis direction along which a light ray passes through the lens module.

[0055] The first lens group and the second lens group can be lens groups arranged in sequence between the object plane end and the image plane end in the lens module. The first lens group can include at least one lens, for example, the first lens group can include 4 lenses, 5 lenses, or 7 lenses, etc. The second lens group can also include at least one lens, for example, the second lens group can include 5 lenses, 6 lenses, or 7 lenses, etc. The embodiments of the present disclosure do not limit this.

[0056] It can be understood that the first lens group and the second lens group can be arranged in sequence between the object plane end and the image plane end along the optical axis direction, and the second lens group can move along the optical axis direction between the first lens group and the image plane end. The optical axis direction can be perpendicular to the surface of each lens in the first lens group and the second lens group.

[0057] That is, the electronic device in which the lens module is located can change the distance between the first lens group and the second lens group and the distance between the second lens group and the image plane end by controlling the second lens group to move along the optical axis direction between the first lens group and the image plane end, so as to change the focal length of the lens module, thereby realizing the continuous zoom function of the lens module.

[0058] It should be noted that the embodiments of the present disclosure can change the focal length of the lens module by controlling the second lens group to move along the optical axis direction between the first lens group and the image plane end; or, the focal length of the lens module can also be changed by controlling the first lens group to move along the optical axis direction between the object plane end and the second lens group, and controlling the second lens group to move along the optical axis direction between the first lens group and the image plane end. The embodiments of the present disclosure do not limit this.

[0059] In some embodiments, as shown in FIG. 1, the first lens group 13 is movably arranged between the object plane end 11 and the image plane end 12, and can move along the optical axis direction F between the object plane end 11 and the second lens group 14. Figure 1

[0060] The first lens group 13 and the second lens group 14 can both move to change the focal length of the lens module 10. ​

[0061] In this way, the interval between the first lens group and the second lens group and the interval between the second lens group and the image plane end can be changed by setting the first lens group and the second lens group to be movable along the optical axis direction between the object plane end and the image plane end, so as to change the focal length of the lens module, thereby more effectively realizing the continuous zoom function of the lens module and better improving the experience of the user in taking a photo by using the electronic device in which the lens module is located.

[0062] Here, the first lens group and the second lens group are both movable and arranged between the object plane end and the image plane end; at this time, the first lens group is movable along the optical axis direction between the object plane end and the second lens group, and the second lens group is movable along the optical axis direction between the first lens group and the image plane end, and the focal length of the lens module is changed by controlling the movement of the two lens groups.

[0063] It can be understood that the electronic device in which the lens module is located can change the interval between the first lens group and the second lens group by controlling the first lens group to move along the optical axis direction between the object plane end and the second lens group, and change the interval between the first lens group and the second lens group and the interval between the second lens group and the image plane end by controlling the second lens group to move along the optical axis direction between the first lens group and the image plane end, so as to change the focal length of the lens module and realize the continuous zoom function of the lens module.

[0064] In some embodiments, the interval between the first lens group and the second lens group is negatively correlated with the focal length of the lens module, and the interval between the second lens group and the image plane end is positively correlated with the focal length of the lens module.

[0065] In this way, the focal length of the lens module can be changed by controlling the interval between the first lens group and the second lens group and controlling the interval between the second lens group and the image plane end, so as to further effectively realize the continuous zoom function of the lens module and improve the experience of the user in taking a photo by using the electronic device in which the lens module is located.

[0066] In the embodiments of the present disclosure, the interval between the first lens group and the second lens group can be the interval between the image side surface of a lens closest to the second lens group in the first lens group and the object side surface of a lens closest to the first lens group in the second lens group. The interval between the second lens group and the image plane end can be the interval between the image side surface of a lens closest to the image plane end in the second lens group and the image plane end. Wherein, the image side surface can refer to the side of the lens facing the image plane end, and the object side surface can refer to the side of the lens facing the object plane end.

[0067] Here, the interval between the first lens group and the second lens group is negatively correlated with the focal length of the lens module, which can be understood as that the larger the interval between the first lens group and the second lens group, the smaller the focal length of the lens module; or the smaller the interval between the first lens group and the second lens group, the larger the focal length of the lens module. The interval between the second lens group and the image plane end is positively correlated with the focal length of the lens module, which can be understood as that the larger the interval between the second lens group and the image plane end, the larger the focal length of the lens module; or the smaller the interval between the second lens group and the image plane end, the smaller the focal length of the lens module.

[0068] For example, during the process of transforming the lens module from the ultra-wide-angle state to the long-focus state, that is, when the focal length of the lens module gradually increases, the interval between the first lens group and the second lens group gradually decreases, and the interval between the second lens group and the image plane end gradually increases. The focal length ratio between the first lens group and the second lens group can be less than or equal to -2, and the change of the focal length of the lens module is realized by the position change of the first lens group and the second lens group.

[0069] It should be noted that, due to the limited internal space of the electronic device in which the lens module is located, the movable space of the first lens group and the second lens group is also limited, that is, the interval between the first lens group and the second lens group is within a first preset range, and the interval between the second lens group and the image plane end is within a second preset range; for example, the first preset range can be 0.3 millimeters (mm) to 5.2 mm, and the second preset range can be 0.92 mm to 3.78 mm.

[0070] In some embodiments, the interval between the first lens group and the second lens group ranges from 0.3 mm to 5.2 mm, and the interval between the second lens group and the image plane end ranges from 0.92 mm to 3.78 mm.

[0071] In this way, by setting the interval between the first lens group and the second lens group to range from 0.3 mm to 5.2 mm, and the interval between the second lens group and the image plane end to range from 0.92 mm to 3.78 mm, the continuous zoom function of the lens module can be effectively realized, and the movable space of the first lens group and the second lens group is further reduced, so as to better realize the miniaturization of the lens module.

[0072] Exemplarily, when the lens module is in the ultra-wide-angle state, the interval between the first lens group and the second lens group can be 5 mm, and the interval between the second lens group and the image plane end can be 1.12 mm; when the lens module is in the wide-angle state, the interval between the first lens group and the second lens group can be 1.53 mm, and the interval between the second lens group and the image plane end can be 2.75 mm; when the lens module is in the telephoto state, the interval between the first lens group and the second lens group can be 0.5 mm, and the interval between the second lens group and the image plane end can be 3.58 mm, and the like.

[0073] In the embodiments of the present disclosure, the focal length of the lens module can be the equivalent focal length of the combination of each lens group in the first lens group and the second lens group; for example, the equivalent focal length of the lens module can be 18 mm, 25 mm or 30 mm, and the like.

[0074] In some embodiments, the focal length range of the lens module is 18 mm to 35 mm. In this way, by setting the focal length range of the combination of each lens group in the first lens group and the second lens group of the lens module to be 18 mm to 35 mm, the continuous zoom function of the lens module from 0.7 to 1.5 times, i.e., from the ultra-wide-angle state to the telephoto state, can be better achieved, and the design requirement of large base and large aperture can be better met.

[0075] Here, the large base can refer to the size of the image sensor of the camera in the electronic device in which the lens module is located; the image sensor with a large size can have stronger photosensitivity and be able to capture more light, thereby showing better imaging effect in low-light environment. The large aperture can refer to the aperture size of the lens module; the large aperture can capture more light, ensuring the brightness and clarity of the picture.

[0076] It should be noted that the focal number (Focal number, FNO), i.e., F value, can refer to the ratio of the focal length of the lens module to the entrance pupil diameter; wherein the smaller the F value, the larger the entrance pupil diameter, i.e., the larger the aperture, which can represent that the larger the light aperture of the lens module, the stronger the light transmission capability, and the lens module can capture more light under the same illumination condition.

[0077] Exemplarily, assuming that the standard focal length of the lens module is 25 mm, when the equivalent focal length of the lens module is 18 mm, the lens module achieves a zoom function of 18 / 25 = 0.72, which is approximately equal to 0.7 times; or when the equivalent focal length of the lens module is 30 mm, the lens module achieves a zoom function of 30 / 25 = 1.2 times; or when the equivalent focal length of the lens module is 35 mm, the lens module achieves a zoom function of 35 / 25 = 1.4 times, and the like.

[0078] The lens module provided by the embodiment of the present disclosure comprises: an object plane end and an image plane end arranged along an optical axis direction; a first lens group located between the object plane end and the image plane end; and a second lens group located between the first lens group and the image plane end and capable of moving along the optical axis direction between the first lens group and the image plane end to change the focal length of the lens module.

[0079] In this way, the first lens group and the second lens group are sequentially arranged between the object plane end and the image plane end arranged along the optical axis direction in the lens module, and the second lens group is capable of moving along the optical axis direction between the first lens group and the image plane end, so that the focal length of the lens module can be changed by changing the distance between the first lens group and the second lens group and the distance between the second lens group and the image plane end, thereby better realizing the continuous zoom function of the lens module and improving the experience of the user in using the electronic device in which the lens module is located to take a photo.

[0080] Figure 2a FIG. 1 is a structural schematic diagram of a lens module in an ultra-wide-angle state according to an example embodiment, Figure 2b FIG. 2 is a structural schematic diagram of a lens module in a wide-angle state according to an example embodiment, Figure 2c FIG. 3 is a structural schematic diagram of a lens module in a long-focus state according to an example embodiment.

[0081] As shown in FIG. 1, Figures 2a-2c when the distance between the first lens group and the second lens group is in a range of 4.8 mm to 5.2 mm and the distance between the second lens group and the image plane end is in a range of 0.92 mm to 1.32 mm, the lens module is in the ultra-wide-angle state;

[0082] when the distance between the first lens group and the second lens group is in a range of 1.33 mm to 1.73 mm and the distance between the second lens group and the image plane end is in a range of 2.55 mm to 2.95 mm, the lens module is in the wide-angle state;

[0083] when the distance between the first lens group and the second lens group is in a range of 0.3 mm to 0.7 mm and the distance between the second lens group and the image plane end is in a range of 3.38 mm to 3.78 mm, the lens module is in the long-focus state.

[0084] In this way, the distance between the first lens group and the second lens group and the distance between the second lens group and the image plane end are respectively controlled to be in different ranges, so that the lens module is controlled to be in different focal lengths, thereby better realizing the continuous zoom function of the lens module and effectively improving the experience of the user in using the electronic device in which the lens module is located to take a photo.

[0085] In the embodiments of the present disclosure, when the lens module is in the ultra-wide-angle state, the focal length range of the lens module can be 8mm to 24mm; at this time, the angle of view range of the lens module can be 80 to 110 degrees, the field of view of the lens module is wide, and a wider scene than a wide-angle lens can be captured. When the lens module is in the wide-angle state, the focal length range of the lens module can be 24mm to 38mm; at this time, the angle of view range of the lens module can be 60 to 84 degrees, the focal length of the lens module is short, the angle of view is large, and the depth of field is long, and a large area of scene can be captured within a short shooting distance. When the lens module is in the long-focus state, the focal length range of the lens module can be 70mm or more; at this time, the angle of view of the lens module is small, the spatial range of the scene captured is small, and the depth of field is short.

[0086] It can be understood that when the distance between the first lens group and the second lens group is controlled to be in the range of 4.8mm to 5.2mm, and the distance between the second lens group and the image plane end is controlled to be in the range of 0.92mm to 1.32mm, the lens module can be in the ultra-wide-angle state; when the distance between the first lens group and the second lens group is controlled to be in the range of 1.33mm to 1.73mm, and the distance between the second lens group and the image plane end is controlled to be in the range of 2.55mm to 2.95mm, the lens module can be in the wide-angle state; when the distance between the first lens group and the second lens group is controlled to be in the range of 0.3mm to 0.7mm, and the distance between the second lens group and the image plane end is controlled to be in the range of 3.38mm to 3.78mm, the lens module can be in the long-focus state.

[0087] It should be noted that when the distance between the first lens group and the second lens group is in the range of 1.73mm to 4.8mm, and the distance between the second lens group and the image plane end is in the range of 1.32mm to 2.55mm, the lens module can be in the ultra-wide-angle-wide-angle state; when the distance between the first lens group and the second lens group is in the range of 0.7mm to 1.33mm, and the distance between the second lens group and the image plane end is in the range of 2.95mm to 3.38mm, the lens module can be in the medium-long focus state.

[0088] In some embodiments, as shown in FIGS. 1 to 3, the first lens group 13 includes at least two lenses, and the second lens group 14 includes at least two lenses. Figure 1 and Figures 2a-2c As shown in FIGS. 1 to 3, the first lens group 13 includes at least two lenses, and the second lens group 14 includes at least two lenses.

[0089] When the first lens group 13 is movable, at least two lenses in the first lens group 13 can move along the optical axis direction F between the object plane end 11 and the second lens group 14.

[0090] When the second lens group 14 is movable, at least two lenses in the second lens group 14 can move along the optical axis direction F between the first lens group 13 and the image plane end 12.

[0091] In this way, at least two lenses can be arranged in the first lens group and the second lens group respectively, and the at least two lenses in the first lens group are movable along the optical axis direction between the object plane end and the second lens group, and the at least two lenses in the second lens group are movable along the optical axis direction between the first lens group and the image plane end, so that the focal length of the lens module can be changed by changing the distance between the first lens group and the second lens group and the distance between the second lens group and the image plane end, thereby more effectively realizing the continuous zoom function of the lens module and improving the experience of the user in taking pictures by using the electronic device provided with the lens module.

[0092] In the embodiments of the present disclosure, the at least two lenses in the first lens group can be arranged in sequence along the optical axis direction between the object plane end and the second lens group, and the first lens group has a distance between any two adjacent lenses; and the at least two lenses in the second lens group can be arranged in sequence along the optical axis direction between the first lens group and the image plane end, and the second lens group has a distance between any two adjacent lenses.

[0093] It should be noted that, when the first lens group is movable, the distance between any two lenses in the first lens group can remain unchanged; when the second lens group is movable, the distance between any two lenses in the second lens group can also remain unchanged. Alternatively, when the first lens group is movable, the distance between any two adjacent lenses in the first lens group can change; when the second lens group is movable, the distance between any two adjacent lenses in the second lens group can also change, and the embodiments of the present disclosure do not make any limitation.

[0094] In some embodiments, as shown in FIG. 1, the at least two lenses in the first lens group 13 include a first lens 131, a second lens 132, a third lens 133, a fourth lens 134 and a fifth lens 135 arranged in sequence along the object plane end 11 to the image plane end 12, and the at least two lenses in the second lens group 14 include a sixth lens 141, a seventh lens 142, an eighth lens 143, a ninth lens 144, a tenth lens 145 and an eleventh lens 146 arranged in sequence along the object plane end 11 to the image plane end 12.

[0095] The first lens 131, the fourth lens 134, the fifth lens 135, the ninth lens 144 and the tenth lens 145 are all crescent-shaped lenses, the second lens 132, the sixth lens 141 and the seventh lens 142 are all double-convex lenses, the third lens 133 and the eighth lens 143 are both double-concave lenses, and the eleventh lens 146 is an arch-shaped lens; the first lens 131, the fourth lens 134, the fifth lens 135 and the ninth lens 144 are all curved towards the image plane end 12, and the tenth lens 145 and the eleventh lens 146 are both curved towards the object plane end 11; and / or, ​

[0096] The first lens 131, the third lens 133, the fifth lens 135, the sixth lens 141, the seventh lens 142, the ninth lens 144 and the eleventh lens 146 are high Abbe number rate materials, and the second lens 132, the fourth lens 134, the eighth lens 143 and the tenth lens 145 are high refractive index materials.

[0097] In this way, the five lenses in the first lens group and the six lenses in the second lens group can be sequentially arranged from the object plane end to the image plane end, and the first lens, the fourth lens, the fifth lens, the ninth lens and the tenth lens are all crescent-shaped lenses, the second lens, the sixth lens and the seventh lens are all double-convex lenses, the third lens and the eighth lens are both double-concave lenses, and the eleventh lens is an arch-shaped lens. In addition, the first lens, the fourth lens, the fifth lens and the ninth lens are all curved towards the image plane end, and the tenth lens and the eleventh lens are both curved towards the object plane end. Therefore, the focal length of the lens module can be changed by changing the distance between the first lens group and the second lens group and the distance between the second lens group and the image plane end, so as to realize the continuous zoom function of the lens module, and effectively improve the user experience of using the electronic device with the lens module. In addition, the first lens, the third lens, the fifth lens, the sixth lens, the seventh lens, the ninth lens and the eleventh lens are all high Abbe number rate materials, which can better reduce the dispersion of light in the lens module and improve the imaging quality of the lens module. Furthermore, the second lens, the fourth lens, the eighth lens and the tenth lens are all high refractive index materials, which can increase the refractive index of the lens module while reducing the weight and volume of the lens module, and improve the portability and comfort of the lens module.

[0098] In the embodiments of the present disclosure, the first lens group can include the first lens, the second lens, the third lens, the fourth lens and the fifth lens, and the second lens group can include the sixth lens, the seventh lens, the eighth lens, the ninth lens, the tenth lens and the eleventh lens.

[0099] Here, the order of the lenses sequentially arranged between the object plane end and the image plane end along the optical axis direction can be the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens, the eighth lens, the ninth lens, the tenth lens and the eleventh lens. Among them, the first lens, the second lens, the third lens, the fourth lens and the fifth lens can be relatively fixed, that is, the distance between any two lenses in the first lens group is fixed and unchanged; the sixth lens, the seventh lens, the eighth lens, the ninth lens, the tenth lens and the eleventh lens can also be relatively fixed, that is, the distance between any two lenses in the second lens group is also fixed and unchanged.

[0100] Understandably, the electronic device containing the lens module can control the movement of the first, second, third, fourth, and fifth lenses as a whole, as well as the sixth, seventh, eighth, ninth, tenth, and eleventh lenses, between the object plane and the image plane to change the spacing between the fifth and sixth lenses and the spacing between the eleventh lens and the image plane, thereby changing the focal length of the lens module, such as switching from an ultra-wide-angle state to a telephoto state.

[0101] For example, such as Figure 2a As shown in Table 1 below, when the lens module 10 is in ultra-wide-angle mode, the distance between the fifth lens 135 and the sixth lens 141 can be in the range of 4.8mm to 5.2mm. For example, the distance between the fifth lens 135 and the sixth lens 141 can be 5mm. The distance between the eleventh lens 146 and the image plane end 12 can be in the range of 0.92mm to 1.32mm. For example, the distance between the eleventh lens 146 and the image plane end 12 can be 1.12mm.

[0102] like Figure 2b As shown in Table 1 below, when the lens module 10 is in wide-angle mode, the distance between the fifth lens 135 and the sixth lens 141 can be in the range of 1.33mm to 1.73mm. For example, the distance between the fifth lens 135 and the sixth lens 141 can be 1.53mm. The distance between the eleventh lens 146 and the image plane end 12 can be in the range of 2.55mm to 2.95mm. For example, the distance between the eleventh lens 146 and the image plane end 12 can be 2.75mm.

[0103] like Figure 2c As shown in Table 1 below, when the lens module 10 is in telephoto mode, the distance between the fifth lens 135 and the sixth lens 141 can be in the range of 0.3mm to 0.7mm. For example, the distance between the fifth lens 135 and the sixth lens 141 can be 0.5mm. The distance between the eleventh lens 146 and the image plane end 12 can be in the range of 3.38mm to 3.78mm. For example, the distance between the eleventh lens 146 and the image plane end 12 can be 3.58mm.

[0104] Table 1

[0105] D1 D2 Ultra-wide angle state 5 1.12 Wide angle state 1.53 2.75 Telephoto state 0.5 3.58

[0106] In Table 1, D1 can refer to the distance between the fifth and sixth lenses, and D2 can refer to the distance between the eleventh lens and the image plane.

[0107] It should be noted that the first lens to the eleventh lens can be lenses of different shapes or different materials, and the embodiments of the present disclosure are not limited.

[0108] In the embodiments of the present disclosure, the meniscus lens can refer to a lens with a convex side and a concave side, the biconvex lens can refer to a lens with two convex sides, the biconcave lens can refer to a lens with two concave sides, and the arch-shaped lens can refer to a lens with an overall arch shape.

[0109] Here, the first lens, the fourth lens, the fifth lens, the ninth lens and the tenth lens can all be meniscus lenses, and the first lens, the fourth lens, the fifth lens and the ninth lens are curved towards the image plane end, and the tenth lens is curved towards the object plane end; that is, the object side of the first lens, the fourth lens, the fifth lens and the ninth lens can be a convex surface, the image side of the first lens, the fourth lens, the fifth lens and the ninth lens can be a concave surface, the object side of the tenth lens can be a concave surface, and the image side of the tenth lens can be a convex surface.

[0110] It can be understood that the high Abbe number material can refer to a small dispersion of the corresponding lens, that is, the refractive ability of the lens to different wavelengths of light is close, which can reduce the chromatic aberration of the lens module. The Abbe number, also known as the dispersion coefficient, is an important indicator for measuring the dispersion ability of the lens material.

[0111] Here, the high refractive index material can determine the degree of deflection when light enters from one medium to another medium. The high refractive index material can refer to a greater degree of deflection of light when passing through the lens, thereby allowing the design of thinner and lighter lenses.

[0112] In some embodiments, at least two lenses in the first lens group and at least two lenses in the second lens group are aspherical lenses.

[0113] In this way, by setting at least two lenses in the first lens group and at least two lenses in the second lens group as aspherical lenses, on the one hand, the aberration existing in the spherical lens can be significantly reduced to provide clearer and more accurate imaging effect; on the other hand, the lens can be made thinner and lighter to make the electronic device on which the lens module is smaller.

[0114] Here, the aspherical lens can be a special designed optical lens, and the surface or any cross section of the aspherical lens is not in the shape of a sphere. The aspherical lens is characterized in that the radius of curvature from the center to the edge changes continuously with the increase of the height, and this change enables the aspherical lens to correct optical aberrations such as spherical aberration, coma, astigmatism and distortion more effectively.

[0115] In the embodiments of the present disclosure, the object side surface of at least two lenses in the first lens group and the object side surface of at least two lenses in the second lens group can be provided as aspheric surfaces, and the image side surface of at least two lenses in the first lens group and the image side surface of at least two lenses in the second lens group can also be provided as aspheric surfaces. The radius of curvature of the aspheric surface changes continuously from the center to the edge with the increase of the height. Such a change enables the aspheric surface to correct optical aberrations such as spherical aberration, chromatic aberration and distortion more effectively, thereby improving the flexibility and optimization space of the radius of curvature of the object side surface and the image side surface of each lens in the first lens group and the second lens group.

[0116] In some embodiments, at least one lens in the first lens group and the second lens group is made of plastic, or at least one lens in the first lens group and the second lens group is made of glass.

[0117] In this way, by setting at least one lens in the first lens group and the second lens group to be made of plastic or at least one lens in the first lens group and the second lens group to be made of glass, the light transmittance of the lens module can be improved, and the imaging effect of the lens module can be improved.

[0118] In the embodiments of the present disclosure, when at least one lens in the first lens group is made of plastic, at least one lens in the second lens group is made of plastic, or each lens in the second lens group is made of glass; when at least one lens in the first lens group is made of glass, at least one lens in the second lens group is made of glass, or each lens in the second lens group is made of plastic.

[0119] For example, when the first lens group includes the first lens to the fifth lens and the second lens group includes the sixth lens to the eleventh lens, the first lens to the eleventh lens can be made of plastic or glass; or the first lens to the eleventh lens can include one glass lens and ten plastic lenses; or the first lens to the eleventh lens can include two glass lenses and nine plastic lenses; or the first lens to the eleventh lens can include three glass lenses and eight plastic lenses, and so on.

[0120] Table 2

[0121]

[0122] For example, as shown in Table 2 above, the object side surface of the first lens, i.e., the surface with surface number 1, the image side surface of the first lens, i.e., the surface with surface number 2, and both the object side surface and the image side surface of the first lens can be aspherical surfaces, and the curvature radius of the object side surface of the first lens can be -16.23 mm, and the curvature radius of the image side surface of the first lens can be 56.50 mm; the thickness of the first lens along the optical axis can be 0.77 mm, and the distance between the image side surface of the first lens and the object side surface of the second lens can be 2.43 mm. Similarly, the object side surface of the fifth lens, i.e., the surface with surface number 9, the image side surface of the fifth lens, i.e., the surface with surface number 10, and both the object side surface and the image side surface of the fifth lens can be aspherical surfaces, and the curvature radius of the object side surface of the fifth lens can be 29.56 mm, and the curvature radius of the image side surface of the fifth lens can be 9.83 mm; the thickness of the fifth lens along the optical axis can be 0.50 mm, and the distance between the image side surface of the fifth lens and the object side surface of the sixth lens can be D1 in Table 1 above.

[0123] By analogy, the object side surface of the eleventh lens, i.e., the surface with surface number 21, the image side surface of the eleventh lens, i.e., the surface with surface number 22, and both the object side surface and the image side surface of the eleventh lens can be aspherical surfaces, and the curvature radius of the object side surface of the eleventh lens can be 14.30 mm, and the curvature radius of the image side surface of the eleventh lens can be 4.30 mm; the thickness of the eleventh lens along the optical axis can be 1.02 mm, and the distance between the image side surface of the eleventh lens and the image plane end can be D2 in Table 1 above.

[0124] In some embodiments, when the lens module is in the ultra-wide-angle state, the aperture value of the lens module is less than or equal to 1.88;

[0125] When the lens module is in the wide-angle state, the aperture value of the lens module is less than or equal to 2;

[0126] When the lens module is in the telephoto state, the aperture value of the lens module is less than or equal to 2.2.

[0127] In this way, by setting the first lens group and the second lens group in the lens module, the aperture value of the lens module is less than or equal to 1.88 when the lens module is in the ultra-wide-angle state, the aperture value of the lens module is less than or equal to 2 when the lens module is in the wide-angle state, and the aperture value of the lens module is less than or equal to 2.2 when the lens module is in the telephoto state, thereby better meeting the design requirements of a large aperture, and improving the user experience of using the electronic device in which the lens module is located to take photos without sacrificing the imaging quality of the lens module.

[0128] In the embodiments of the present disclosure, the aperture value of the lens module can refer to the aperture coefficient FNO of the lens module, that is, the F value; the smaller the aperture value is, the larger the entrance pupil diameter is, that is, the larger the aperture is, which can represent that the larger the light aperture of the lens module is and the stronger the light transmission capability is, so as to meet the design requirement of the large aperture of the lens module and improve the imaging brightness and definition of the lens module.

[0129] Here, when the focal length of the lens module changes to the focal length range corresponding to the ultra-wide angle state, such as the focal length of the lens module changes to 18 mm, the FNO of the lens module is less than or equal to 1.88; when the focal length of the lens module changes to the focal length range corresponding to the wide angle state, such as the focal length of the lens module changes to 30 mm, the FNO of the lens module is less than or equal to 2; when the focal length of the lens module changes to the focal length range corresponding to the telephoto state, the FNO of the lens module is less than or equal to 2.2.

[0130] In some embodiments, the imaging height of the lens module is greater than or equal to 16 mm. In this way, by setting the first lens group and the second lens group in the lens module, the imaging height of the lens module can be greater than or equal to 16 mm, so as to meet the design requirement of the large base, so as to improve the shooting experience of the user in the process of shooting with the large base without losing the pixels and imaging quality of the lens module.

[0131] In the embodiments of the present disclosure, the imaging height of the lens module can refer to the image height after the light passes through the lens module and is imaged in the image sensor.

[0132] Here, the size of the image sensor of the camera in the electronic device in which the lens module is located is large, that is, the large base, and the corresponding imaging height of the lens module in the image sensor is also large; for example, the imaging height of the lens module in the image sensor is greater than or equal to 16 mm, so as to capture more light, thereby showing better imaging effect in a low light environment.

[0133] In some embodiments, the ratio between the total optical length of the lens module and the imaging height of the lens module is less than or equal to 1.75. In this way, by setting the first lens group and the second lens group in the lens module, the ratio between the total optical length of the lens module and the imaging height of the lens module is less than or equal to 1.75, so as to better realize the miniaturization of the lens module.

[0134] In the embodiments of the present disclosure, the total optical length (TTL) of the lens module can refer to the distance from the object side surface of the first lens in the lens module to the image surface end.

[0135] It can be understood that the ratio between the total optical length of the lens module and the imaging height of the lens module can be used to represent the space occupied by the lens module in the electronic device, that is, the smaller the ratio between the total optical length of the lens module and the imaging height of the lens module, the more the lens module can be miniaturized.

[0136] As shown in Figure 3a , Figure 3a a distortion curve diagram of the lens module in the wide-angle state is shown, the abscissa of the distortion curve diagram identifies the distortion parameter of the lens module in the wide-angle state, and the ordinate identifies the imaging height of the lens module in the wide-angle state. As shown in Figure 3b , Figure 3b a spherical aberration curve diagram of the lens module in the wide-angle state is shown, the abscissa of the spherical aberration curve diagram identifies the focal length of the lens module in the wide-angle state, and the ordinate identifies the longitudinal spherical aberration of the lens module in the wide-angle state, Figure 3b the optical distortion level of the lens in the wide-angle state can be reflected; Figure 3b The curves identified by different shapes in the figure can be the mapping relationship between the focal length and the longitudinal spherical aberration of the lens module under different wavelengths of incident light.

[0137] As shown in Figures 4a-4c , Figure 4a a diffraction modulation schematic diagram of the lens module in the ultra-wide-angle state is shown, Figure 4b a diffraction modulation schematic diagram of the lens module in the wide-angle state is shown, Figure 4c a diffraction modulation schematic diagram of the lens module in the telephoto state is shown; Figures 4a-4c The lines identified by different shapes in the figure can refer to the mapping relationship between the spatial frequency and the diffraction modulation transfer function (Modulation Transfer Function, MTF) of the lens module under different fields of view or different imaging heights of the lens module. The spatial frequency is a parameter describing the speed of spatial change of light intensity in an image, and the MTF is an index for measuring the ability of the lens module to transfer various frequency sine modulation systems. From Figures 4a-4c It can be seen from the figure that the imaging performance and quality of the lens module are different under different fields of view or different imaging heights of the lens module.

[0138] In the related art, as Figure 5As shown, the conventional lens module 20 can include, in order from the object side to the image side, i.e., the imaging surface 25, a light guide element 21, a first lens group 22, a second lens group 23, and a third lens group 24; wherein the first lens group 22 can include two lenses, the second lens group 23 can include three lenses, and the third lens group 24 can include two lenses. The conventional lens module 20 achieves an optimal balance state during zooming by limiting the relationship between the radii of curvature of the lenses, which is conducive to achieving a large zoom ratio to realize continuous zooming design from the medium focal length to the long focal length end; and the conventional lens module 20 can satisfy 3≤FNO≤5, which does not meet the current design requirements of large base and large aperture for optical lenses.

[0139] Based on this, the lens module provided by the embodiments of the present disclosure can sequentially arrange the first lens group and the second lens group between the object surface end and the image surface end arranged along the optical axis direction in the lens module, and the second lens group can move along the optical axis direction between the first lens group and the image surface end, so as to change the focal length of the lens module by changing the distance between the first lens group and the second lens group and the distance between the second lens group and the image surface end, thereby better realizing the continuous zooming function of the lens module from 0.7 to 1.5 times, i.e., from the super wide-angle state to the long focal length state, and improving the experience of the user using the electronic device in which the lens module is located to take a photo; and the lens module can better realize the miniaturization while meeting the design requirements of large base and large aperture.
