The invention discloses an intelligent headlamp projection lens and an intelligent headlamp projection lens module. The intelligent headlamp projection lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are sequentially arranged from an image side to an object side along an optical axis, the second lens has negative focal power; the third lens has positive focal power; the object side surface of the fourth lens is a concave surface close to the optical axis; a fifth lens element having a convex image-side surface near the optical axis; the intelligent headlamp projection lens meets the following conditional expressions: # imgabs0 # 0.927 < = f1/f < = 1.410; tTL is the distance from the image side surface of the first lens to the imaging surface of the intelligent headlamp projection lens on the optical axis; the # imgabs 1 # is the effective aperture of the image side surface of the projection lens of the intelligent headlamp; f1 is the effective focal length of the first lens of the intelligent headlamp projection lens; f is the effective focal length of the projection lens of the intelligent headlamp. At least one of a large projection light field angle, a small size, high brightness and high imaging quality is realized.
