     Exemplary Embodiments 
     The optical imaging lens assembly according to an exemplary embodiment of the disclosure includes seven lenses, which sequentially includes from an object side to an image side along an optical axis: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens, wherein, each lens is independent of each other, and there is an air space between each lens on the optical axis. 
     In an exemplary embodiment, the first lens has a positive refractive power; the second lens has a positive refractive power or a negative refractive power; the third lens has a positive refractive power or a negative refractive power; the fourth lens has a positive refractive power or a negative refractive power; the fifth lens has a positive refractive power or a negative refractive power, an object-side surface thereof is a convex surface, and an image-side surface thereof is a concave surface; the sixth lens has a positive refractive power, an object-side surface thereof is a convex surface, and an image-side surface thereof is a concave surface; and the seventh lens has a negative refractive power. Reasonable matching of the refractive power and surface shapes of each lens in the optical imaging system is not only conducive to a rationality of the structure of the optical imaging lens assembly, but also conducive to a ultra-clear photographing function of the lens and reducing the system tolerance sensitivity. 
     In an exemplary embodiment, TTL is an on-axis distance from an object-side surface of the first lens to an imaging surface, ImgH is a half of a diagonal length of an effective pixel region on the imaging surface, TTL and ImgH satisfy the following condition: TTL/ImgH&lt;1.25. A smaller compression ratio of a total length of structure of a wide-angle lens and an image surface can be achieved, a ultra-thin design effect is achieved, which is beneficial to a miniaturization of the system. More specifically, TTL and ImgH satisfy: 1.12≤TTL/ImgH≤1.21. 
     In an exemplary embodiment, an effective focal length f of the optical imaging lens assembly and a maximum field of view FOV of the optical imaging lens assembly satisfy: 4.8 mm&lt;f×tan(1/2FOV)&lt;6.5 mm.

More specifically, 4.95 mm≤f×tan(1/2FOV)≤6.01 mm. 
     In an exemplary embodiment, an effective focal length f of the optical imaging lens assembly and an Entrance Pupil Diameter (EPD) of the optical imaging lens assembly satisfy: f/EPD&lt;1.9. By controlling a ratio range of the effective focal length f of the optical imaging lens assembly to the Entrance Pupil Diameter (EPD) of the optical imaging lens assembly, a luminous flux of the lens can be effectively increased, a relative illumination is high, an imaging quality of the lens in the darker environment can be well improved, and customers can have a better experience in the dark environment.

     In an exemplary embodiment, an effective focal length f6 of the sixth lens, a curvature radius R12 of the image-side surface of the sixth lens and a curvature radius R11 of the object-side surface of the sixth lens satisfy: 0.7&lt;f6/(R11+R12)&lt;1.5. By controlling the effective focal length of the sixth lens and a curvature radius of the image-side surface of the object-side surface of the sixth lens, a total large aperture effect can be improved, and a field curvature and a chromatic aberration can be avoided, meanwhile, an astigmatism and a spherical aberration are not easily generated. More specifically, 0.75≤f6/(R11+R12)≤1.37. 
     In an exemplary embodiment, an effective focal length f4 of the fourth lens and an effective focal length f1 of the first lens satisfy: 2.2&lt;f4/f1&lt;3.2. By reasonably adjusting the effective focal length of the first lens and the fourth lens, not only can the refractive power of the lens group be distributed more reasonably, which is not excessively concentrated on the fourth lens, and is conducive to improving an imaging quality of the system and reducing a sensitivity of the system, but also can keep the ultra-thin characteristics of the lens group. More specifically, 2.36≤f4/f1≤3.00. 
     In an exemplary embodiment, an effective focal length f3 of the third lens and an effective focal length f7 of the seventh lens satisfy: 1.0&lt;(f3+f7)/(f3−f7)&lt;1.5. By reasonably distributing the effective focal length of the third lens and the effective focal length of the seventh lens, a size of the lens group can be shortened more effectively, so that the ultra-thin characteristics can be maintained, the excessive concentration of the refractive power of the system can be avoided, and the system aberration can be better corrected by matching 2.2&lt;f4/f1&lt;3.2. More specifically, 1.26≤(f3+f7)/(f3−f7)≤1.31.

By reasonably distributing the curvature radius of an object-side surface of the first lens, the curvature radius of the object-side surface and the image-side surface of the second lens, it will help to balance various aberrations of the system, correct the aberrations of the system and improve the imaging quality of the lens group. More specifically, 1.53≤(R3+R4)/(R1+R2)≤1.96. 
     In an exemplary embodiment, a curvature radius R10 of the image-side surface of the fifth lens and a curvature radius R9 of the object-side surface of the fifth lens satisfy: 0.8&lt;R9/R10&lt;1.3. Controlling the curvature radius of the image-side surface of the fifth lens and the curvature radius of the object-side surface of the fifth lens is helpful to increase a subject space, reduce an aberration of the edge field of view and improve an image quality. More specifically, 0.95≤R9/R10≤1.20. 
     In an exemplary embodiment, a curvature radius R14 of an image-side surface of the seventh lens, a curvature radius R13 of an object-side surface of the seventh lens and a center thickness CT7 of the seventh lens on the optical axis satisfy: 1.7&lt;(R13+R14)/CT7&lt;3.4. By reasonably controlling the curvature radius of the object-side surface and the image-side surface of the seventh lens and the center thickness of the seventh lens on the optical axis, an astigmatism and a coma of the seventh lens can be effectively balanced. More specifically, 1.82≤(R13+R14)/CT7≤3.21. 
     In an exemplary embodiment, an air space T67 between the sixth lens and the seventh lens on the optical axis and a center thickness CT6 of the sixth lens on the optical axis satisfy: 2.0&lt;T67/CT6&lt;2.8. By controlling the air space between the sixth lens and the seventh lens on the optical axis and the center thickness of the sixth lens on the optical axis in a reasonable range, the lens group can better balance the system chromatic aberration, meanwhile, the sixth lens does not cause difficulty in a processing technology due to too thin. More specifically, 2.10≤T67/CT6≤2.63. 
     In an exemplary embodiment, a combined focal length f12 of the first lens and the second lens, a center thickness CT1 of the first lens on the optical axis and a center thickness CT2 of the second lens on the optical axis satisfy: 6.6&lt;f12/(CT1+CT2)&lt;8.6. Reasonable control of the combined focal length of the first lens and the second lens and the center thickness of the first lens on the optical axis and the center thickness of the second lens on the optical axis are beneficial to achieve a miniaturization of the system, reduce a ghost image risk, reduce the chromatic aberration of the system effectively in the matching of the first two lenses, meanwhile, avoid the technological difficulties caused by the thinness of the first two lenses. More specifically, 6.74≤f12/(CT1+CT2)≤8.48. 
     In an exemplary embodiment, SAG51 is an on-axis distance between an intersection point of the object-side surface of the fifth lens and the optical axis and an effective radius vertex of the object-side surface of the fifth lens, SAG52 is an on-axis distance between an intersection point of the image-side surface of the fifth lens and the optical axis and an effective radius vertex of the image-side surface of the fifth lens, SAG41 is an on-axis distance between an intersection point of an object-side surface of the fourth lens and the optical axis and an effective radius vertex of the object-side surface of the fourth lens, and SAG42 is an on-axis distance between an intersection point of an image-side surface of the fourth lens and the optical axis and an effective radius vertex of the image-side surface of the fourth lens, and SAG51, SAG52, SAG41 and SAG42 satisfy: 1.7&lt;(SAG51+SAG52)/(SAG41+SAG42)&lt;2.5. Reasonable control of this conditional expression is firstly helpful to improve an effective focal length of the system while maintaining an imaging quality of the lens group; Secondly, it is helpful to improve a spherical aberration of the middle field of view and a coma of the edge field of view, and enabling the system to have better aberration correction ability; Thirdly, it is helpful to increase a relative illumination of the system and improve an imaging quality of the lens in a darker environment. More specifically, 1.82≤(SAG51+SAG52)/(SAG41+SAG42)≤b  2 . 34 . 
     In an exemplary embodiment, SAG71 is an on-axis distance between an intersection point of an object-side surface of the seventh lens and the optical axis and an effective radius vertex of the object-side surface of the seventh lens, SAG61 is an on-axis distance between an intersection point of the object-side surface of the sixth lens and the optical axis and an effective radius vertex of the object-side surface of the sixth lens, and SAG71 and SAG61 satisfy: 1.6&lt;SAG71/SAG61&lt;2.3. Reasonable control of this conditional expression, firstly, makes the a ray has a certain convergence function when passing through the object-side surface of the seventh lens, and better improves an aberration correction ability of the system; Second, it is helpful for the system to obtain a smaller F-number; The third point is to avoid the process problems such as processing difficulties caused by the oversized SAG71. More specifically, 1.89≤SAG71/SAG61≤2.15. 
     In an exemplary embodiment, the above optical imaging lens assembly may further include a diaphragm. The diaphragm may be arranged at an appropriate position as required, for example, the diaphragm may be arranged between the object side and the first lens. In an embodiment, the above optical imaging lens assembly may further include an optical filter for correcting color deviation and/or a protective glass for protecting photosensitive elements located on the imaging surface. 
     The optical imaging lens assembly according to the above embodiment of the disclosure may adopt multiple lenses, such as the above-mentioned seven lenses. By reasonably distributing the refractive power, surface type, center thickness of each lens and on-axis spacing distance between each lens, the optical imaging lens assembly has a larger imaging image surface, has the characteristics of wide imaging range and high imaging quality, and ensures the ultra-thinness of the mobile phone. 
     In an exemplary embodiment, at least one mirror surface of each lens is an aspheric mirror surface, that is, at least one mirror surface from the object-side surface of the first lens to the image-side surface of the seventh lens is an aspheric mirror surface. The characteristic of aspheric lens is that: the curvature changes continuously from the center of lens to the periphery of lens, and different from the spherical lens with constant curvature from the center of the lens to the periphery of the lens, the aspheric lens has better curvature radius characteristics and has the advantages of improving distortion aberration and astigmatism aberration. After adopting aspheric lens, the aberration during imaging can be eliminated as much as possible, thus improving the imaging quality. In an embodiment, at least one of the object-side surface and the image-side surface of each lens of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens and the seventh lens is an aspheric mirror surface. In another embodiment, the object-side surface and the image-side surface of each lens of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens and the seventh lens are all aspheric mirror surfaces. 
     However, those skilled in the art should understand that the number of lens constituting the optical imaging lens assembly can be changed to obtain the results and advantages described in this description without departing from the technical solution claimed in this application. For example, although the embodiment has been described with seven lenses as an example, the optical imaging lens assembly is not limited to seven lenses, but may further include other numbers of lens if necessary.

       FIG. 10 a    shows a longitudinal aberration curve of the optical imaging lens assembly according to Embodiment 5, to represent deviations of a convergence focal point after light with different wavelengths passes through the lens.  FIG. 10 b    shows an astigmatism curve of the optical imaging lens assembly according to Embodiment 5, to represent a tangential image surface curvature and a sagittal image surface curvature.  FIG. 10 c    shows a distortion curve of the optical imaging lens assembly according to Embodiment 5, to represent distortion values corresponding to different image heights.  FIG. 10 d    shows a lateral color curve of the optical imaging lens assembly according to Embodiment 5, to represent deviations of different image heights on the imaging surface after the light passes through the lens. According to  FIGS. 10 a -10 d   , it can be seen that the optical imaging lens assembly given in Embodiment 5 may achieve good imaging quality.
