1. An optical imaging lens, sequentially comprising a first lens element, a second lens element, a third lens element, and a fourth lens element along an optical axis from an object side to an image side, wherein each of the first lens element to the fourth lens element comprises an object-side surface facing the object side and allowing imaging rays to pass through, and an image-side surface facing the image side and allowing the imaging rays to pass through;
the first lens element has negative refracting power, and a periphery region of the object-side surface of the first lens element is convex;
at least one of an optical axis region of the object-side surface of the second lens element and an optical axis region of the image-side surface of the second lens element is plane;
the third lens element has negative refracting power or the fourth lens element has positive refracting power;
lens elements of the optical imaging lens are only the four lens elements, and the optical imaging lens satisfies HFOV/(Tmax+Tmax2)≥39.000 degrees/mm and T2/T3 ≤ 2,000, where HFOV is a half field of view of the optical imaging lens, Tmax is a maximum value of thicknesses of the four lens elements from the first lens element to the fourth lens element on the optical axis, Tmax2 is a second largest value of thicknesses of the four lens elements from the first lens element to the fourth lens element on the optical axis, T2 is a thickness of the second lens element on the optical axis, and T3 is a thickness of the third lens element on the optical axis.
