Claim 3:
4. A periscope camera lens, comprising:
a camera module; and
a prism module provided at an end of the camera module,
wherein the camera module comprises:
a shell having a receiving cavity;
a lens assembly provided in the receiving cavity and movable relative to the shell;
at least one focusing and driving assembly provided in the receiving cavity and configured to drive the lens assembly to move in a direction of an optical axis;
at least one image stabilization and driving assembly provided in the receiving cavity and configured to drive the lens assembly to move in a first direction perpendicular to the optical axis; and
at least one supporting and guiding assembly provided in the receiving cavity and configured to support the lens assembly and guide a movement of the lens assembly,
wherein each of the at least one supporting and guiding assembly comprises a first magnetic portion fixed to the lens assembly, a second magnetic portion fixed to the shell and spaced from and opposite to the first magnetic portion, and a ball provided between the first magnetic portion and the second magnetic portion; the lens assembly is connected to the shell through the at least one supporting and guiding assembly in a rollable way; the first magnetic portion and the second magnetic portion mutually attract in a direction perpendicular to the optical axis and the first direction in such a manner that the lens assembly is suspended in the receiving cavity; and the ball is rollable between the first magnetic portion and the second magnetic portion to guide the lens assembly;
wherein an avoiding groove is formed by recessing from a side of the first magnetic portion and/or the second magnetic portion close to the ball along a direction facing away from the ball, and the ball is received in the avoiding groove and is rollable in the avoiding groove;
wherein the first magnetic portion comprises a first supporting portion fixed to the lens assembly and a first magnet embedded into the first supporting portion; the second magnetic portion comprises a second supporting portion fixed to the shell and a second magnet embedded into the second supporting portion; and the ball is arranged between the first supporting portion and the second supporting portion, and the avoiding groove is formed in the first supporting ortion and/or the second supporting portion;
wherein the lens assembly comprises a bracket spaced apart from the shell and a lens module mounted to the bracket, and the first magnetic portion is fixed to the bracket;
wherein the first supporting portion is formed on the bracket and formed into one piece with the bracket, and/or the second supporting portion is formed on the shell;
wherein the bracket comprises supporting arms that are opposite to and spaced apart from each other in the first direction, and bottom arms connected between the supporting arms, and the lens module is supported by the bottom arms and is located between the supporting arms;
a first receiving groove is formed by recessing from a side of each of the supporting arms facing away from the second magnetic portion, and each of the at least one image stabilization and driving assembly comprises: a first magnetic block fixed to the first receiving groove, and a first coil fixed to the shell; and the first coil cooperates with the first magnetic block to drive the lens assembly to move in the first direction;
the at least one image stabilization and driving assembly comprises two image stabilization driving assemblies that are symmetrically distributed at two sides of a central axis of the lens assembly;
wherein a second receiving groove is formed by recessing from a side of each of the supporting arms facing away from the lens module, and each of the at least one focusing and driving assembly comprises: a second magnetic block fixed to the second receiving groove, and a second coil fixed to the shell; and the second coil cooperates with the second magnetic block to drive the lens assembly to move along the optical axis of the lens assembly;
the at least one focusing and driving assembly comprises two focusing and driving assemblies that are symmetrically distributed at both sides of the central axis of the lens assembly; and
the first receiving groove is perpendicular to the second receiving groove.
