1. An optical imaging lens assembly, comprising, sequentially along an optical axis from an object side to an image side:
a first lens having a refractive power;
a second lens having a refractive power, an object-side surface of the second lens being a concave surface;
a third lens having a refractive power, an object-side surface of the third lens being a concave surface at the optical axis;
a diaphragm;
a fourth lens having a refractive power;
a fifth lens having a negative refractive power, an object-side surface of the fifth lens being a concave surface; and
a sixth lens having a negative refractive power, an image-side surface of the sixth lens being a convex surface at the optical axis,
wherein half of a maximal field-of-view Semi-FOV of the optical imaging lens assembly satisfies: Semi-FOV≥70°, and
a distance TTL from an object-side surface of the first lens to an image plane of the optical imaging lens assembly on the optical axis and a total effective focal length f of the optical imaging lens assembly satisfy: 3.5<TTL/f<5.1.
