Electronic device having a lens assembly employing an avoidance space in conjunction with a total track length

An electronic device, comprising a housing, a lens cover, and a lens assembly disposed in the housing, wherein:

• the lens assembly comprises a plurality of lenses sequentially arranged from an object side to an image side along an optical axis;
• the lens cover is located on one side that is of the lens assembly and that faces the object side, the lens cover extends out of the housing along the optical axis to form avoidance space, and at least one lens that is in the lens assembly and that is close to the object side is configured to move in the avoidance space along the optical axis;
• the lens assembly satisfies a conditional expression:
• 0.7<IH/(4*F #)<6, wherein IH is a total image height of the lens assembly, and F # is an F-number of the lens assembly;
• and
• an equivalent focal length of the lens assembly is between 18 mm and 30 mm.
