Abstract

The invention provides a lens transmission device. The lens transmission device comprises a driving assembly, a first transmission assembly and a second transmission assembly. The first transmission assembly comprises a linear transmission assembly and a rotary driving nut. The second transmission assembly comprises a second sleeve, a rotating assembly and a spring. The rotating assembly comprisesa rotating screw rod and a rotating shaft connected to the rotating screw rod. The driving assembly drives the linear transmission assembly to move linearly in the first direction. The second transmission assembly is pushed to move along the first direction through the interaction of the linear transmission assembly and the spring. When the second transmission assembly moves to the limiting position in the first direction, the linear transmission assembly drives the rotary driving nut to move in the first direction, so that the rotary screw and the rotary driving nut rotate relatively, and the rotary shaft is driven to rotate along the axis of the rotary screw. Compared with the prior art, the lens transmission device is simple in structure, small in occupied space and high in practicability.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a lens transmission device and a lens assembly used in portable electronic products. Background technique [0002] With the continuous development of mobile terminal products, the requirements for the screen ratio of the screen are getting higher and higher, especially in the solution of using a full screen, which requires no other components to be installed on the side of the screen. Therefore, in order to avoid camera The lens is set on one side of the screen, and a pop-up camera solution is required to meet the needs of a full-screen design. [0003] In the lens assembly of the related art, the lens assembly includes a lens module and a lens transmission device for controlling the lifting or rotation of the lens module, and the lens transmission device includes a first motor for controlling the lifting and ejection of the lens module And a second motor for controlling the ...
