Abstract

The invention relates to the technical field of electronic products, and particularly discloses an optical imaging lens, a camera shooting module, electronic equipment and an automobile. The optical imaging lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens which are sequentially arranged from the object side to the image side, wherein the optical imaging lens meets the conditional expression that f2 / f is greater than -20 and less than-13, f2 is the focal length of the second lens, and f is the effective focal length of the optical imaging lens. According to the optical imaging lens, the seven lenses respectively with the negative refractive power, the negative refractive power, the positive refractive power, the positive refractive power, the negativerefractive power, thepositive refractive power andthe positive refractive power are arranged, the aberration of the optical imaging lens can be corrected, astigmatism can be eliminated, the imaging resolution of the optical imaging lens can be improved, and the optical imaging lens can be balanced in the aspects of field angle range expansion and high pixel. When the optical imaging lens is used in a camera of a vehicle, the driving risk can be reduced.

Description

technical field [0001] The present application relates to the technical field of electronic products, in particular to an optical imaging lens, a camera module, electronic equipment and an automobile. Background technique [0002] With the development of the vehicle industry, the technical requirements for vehicle cameras such as front view, automatic cruise control, driving recorder, and reversing image are getting higher and higher. The front-view camera is an on-board camera installed in front of the car. It can be used as a camera system in an advanced driver assistance system to analyze video content and provide lane departure warning (LDW), automatic lane keeping assist (LKA), high beam / low beam Control and Traffic Sign Recognition (TSR). When it is turned on when parking, you can intuitively see the obstacles in front of the car, making parking more convenient. Realize that when the car passes through special places (such as roadblocks, parking lots, etc.), turn on ...
