wherein,
a total number of lenses comprised in the optical lens assembly is six;
an object-side surface of the first lens is a convex surface, and an image-side surface of the first lens is a concave surface;
the second lens has negative refractive power;
the third lens has positive refractive power;
the fourth lens has positive refractive power, and each of an object-side surface and an image-side surface of the fourth lens is convex surface;
the fifth lens has positive refractive power; and
the sixth lens has negative refractive power,
wherein TTL/F≤3.5,
where TTL is a total track length of the optical lens assembly, and F is a total focal length of the optical lens assembly.
