1. A camera lens assembly, comprising, sequentially 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 and a sixth lens,
wherein,
the first lens has negative refractive power, and an image-side surface of the first lens is a concave surface;
the second lens has negative refractive power, an object-side surface of the second lens is a convex surface, and an image-side surface of the second lens is a concave surface;
the third lens has positive refractive power, and an image-side surface of the third lens is a convex surface;
the fourth lens has refractive power;
the fifth lens has refractive power; and
the sixth lens has positive refractive power,
wherein 5.59 mm≥ImgH2/f>4.5 mm,
1.43≤DT11/ImgH<1.8,
−1<f1/f3<−0.5, and
−8<f2/f3<−3,
where ImgH is half of a diagonal length of an effective pixel area of an electronic photosensitive element on an imaging plane of the camera lens assembly, f is a total effective focal length of the camera lens assembly, DT11 is an effective half-aperture of an object-side surface of the first lens, f1 is an effective focal length of the first lens, f3 is an effective focal length of the third lens, and f2 is an effective focal length of the second lens.
