1. An optical imaging lens assembly, sequentially comprising a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens with refractive powers, from an object side to an image side along an optical axis, wherein
the first lens has a positive refractive power, and an image-side surface of the first lens is a concave surface;
the second lens has a negative refractive power;
the fifth lens has a negative refractive power, and an object-side surface of the fifth lens is a concave surface; and
a distance TTL from an object-side surface of the first lens to an imaging surface of the optical imaging lens assembly on the optical axis and a total effective focal length f of the optical imaging lens assembly satisfy TTL/f≤0.85;
wherein an axial distance SAG52 from an intersection point of an image-side surface of the fifth lens and the optical axis to an effective radius vertex of the image-side surface of the fifth lens and an axial distance SAG62 from an intersection point of an image-side surface of the sixth lens and the optical axis to an effective radius vertex of the image-side surface of the sixth lens satisfy 0.3<SAG52/SAG62<0.8.
