Optical lens assembly and electronic device

An optical lens assembly, comprising:

• a first lens having a negative refractive power, a second side surface of the first lens is a concave surface;
• a second lens having a negative refractive power, a first side surface of the second lens is a concave surface;
• a third lens having a positive refractive power, a second side surface of the third lens is a convex surface;
• a fourth lens having a positive refractive power, a first side surface of the fourth lens is a convex surface;
• a fifth lens having a refractive power, a first side surface of the fifth lens is a convex surface;
• a sixth lens having a refractive power;
• and
• a seventh lens having a refractive power;
• wherein refractive powers of the fifth lens and the sixth lens are opposite;
• a distance d11 from a second side surface of the sixth lens to a first side surface of the seventh lens on an optical axis of the optical lens assembly and a total optical length TTL of the optical lens assembly meet:
• d11/TTL≥0.03;
• a distance d7 from a second side surface of the fourth lens to the first side surface of the fifth lens on the optical axis of the optical lens assembly and the total optical length TTL of the optical lens assembly meet:
• d7/TTL≥0.09;
• and
• a focal length F7 of the seventh lens and a focal length F of the optical lens assembly meet:
• |F7/F|≥2.5.
