Problems solved by technology
[0002] With the popularization of smart phones, the application range of mobile phone cameras is increasing. However, the current lens drive mechanism has electromagnetic technology and magnetic interference. Need to use sensors to assist actual operation
As for memory alloy-driven solutions, most of the current solutions use a single memory alloy, or two memory alloys are distributed one above the other, and the thrust in one direction is not enough to support the current market demand.

The invention discloses an optical element driving mechanism. The optical element driving mechanism comprises a shell, a base, a frame, a carrier, an upper reed, a lower reed, a first group of memoryalloys and a second group of memory alloys, wherein the frame, the carrier, the upper reed, the lower reed, the first group of memory alloys and the second group of memory alloys are arranged in a space defined by the shell and the base; the frame is movably connected with the carrier through the upper reed; the lower reed enables the base to be movably connected with the carrier, the first groupof memory alloys is installed on one pair of opposite side portions of the carrier to drive the carrier to move towards one direction along the optical axis, and the second group of memory alloys is installed on the other pair of opposite side portions of the carrier to drive the carrier to move towards the other direction along the optical axis. Maximum thrust can be provided, and the problem ofinsufficient thrust is solved.
Description
technical field [0001] The invention relates to the technical field of medical imaging equipment, in particular to an optical element driving mechanism. Background technique [0002] With the popularization of smart phones, the application range of mobile phone cameras is increasing. However, the current lens drive mechanism has electromagnetic technology and magnetic interference. Need to use sensors to assist the actual operation. As for memory alloy-driven solutions, most of the current solutions use a single memory alloy, or two memory alloys are distributed one above the other, and the thrust in one direction is not enough to support the current market demand. Contents of the invention [0003] The object of the present invention is to provide an optical element driving mechanism to solve the above-mentioned problems in the prior art. [0004] In order to solve the above problems, according to one aspect of the present invention, an optical element driving mechanism...
