1. An optical imaging lens assembly, along an optical axis from an object side to an image side, sequentially comprising:
a first lens having a positive refractive power, and an image-side surface of the first lens is a flat surface;
an autofocus component having a refractive power;
a second lens having a refractive power;
a third lens having a refractive power;
a fourth lens having a refractive power; and
at least one subsequent lens having a refractive power;
wherein the first lens and the autofocus component are cemented together;
a radius of curvature of an image-side surface of the autofocus component is variable;
a distance TTL from an object-side surface of the first lens to an imaging plane of the optical imaging lens assembly on the optical axis, a sum of center thicknesses D of the autofocus component and the first lens on the optical axis, and a center thickness CT1 of the first lens on the optical axis satisfy: 3.0<TTL/(D+CT1)<4.0; and
at least one surface from an object-side surface of the first lens to an image-side surface of the at least one subsequent lens is an aspheric surface.
