Embodiment 1

[0031] see Figure 1-4 , Embodiment 1 of the present invention provides an optical anti-shake assembly 100, including a first base 10, a second base 20, and three shape memory alloy wires 30, the first base 10 is ring-shaped, and the second base 20 Spaced on the inside of the first base 10, the second base 20 is provided with mounting holes 21 for lens mounting. Each shape memory alloy wire 30 includes a first fixed end 31 fixed on the first base 10, a first extension section 32 extending from the first fixed end 31 toward the second base 20, and fixed on the second base. The second fixed end 33 of 20, the second extension section 34 extending from the second fixed end 33 toward the direction of the first base 10, and the third fixed end 34 connected with the second extension section 34 and fixed on the first base 10 end 35, the first fixed end 31 and the third fixed end 35 are spaced apart, and the end of the first extension section 32 away from the first fixed end 31 is fix...

Embodiment 2

[0046] see Figure 8 The main difference between the optical anti-shake assembly 200 provided in this embodiment and the optical anti-shake assembly 100 provided in Embodiment 1 is that the arrangement of the three shape memory alloy wires is different, which is specifically reflected in: in this embodiment, the second side plate 201 is provided with only one connection terminal 202, and the fourth side plate 203 is provided with two connection terminals 202, the first fixed end and the third fixed end of the third shape memory alloy wire 204 are fixed to the fourth side plate 203 The two terminals 202.

Abstract

The invention discloses an optical anti-shake assembly which comprises an annular first base, a second base arranged on the inner side of the first base at an interval and used for installing a lens,and three shape memory alloy wires. Each shape memory alloy wire comprises a first fixing end fixed to the first base, a first extending section extending from the first fixing end to the second base,a second fixing end fixed to the second base, a second extending section extending from the second fixing end to the first base, and a third fixing end connected with the second extending section andfixed to the first base. The first fixing end and the third fixing end are arranged in a spaced mode, the included angle between two driving force generated by every two adjacent shape memory alloy wires on the second base is smaller than 180 degrees when the two adjacent shape memory alloy wires are powered on, and the reverse extension lines of the driving force generated by the shape memory alloy wires are gathered at one point. The optical anti-shake assembly has the advantages of being simple in structure and low in production cost.

Description

【Technical field】 [0001] The invention relates to the technical field of lens optical imaging, in particular to an optical anti-shake component. 【Background technique】 [0002] In recent years, high-performance lens modules have been mounted on portable terminals such as smartphones and tablet computers. The high-performance lens module generally has an auto focusing function (Auto Focusing, AF) and an optical image stabilization function (Optical Image Stabilization, OIS). The high-performance lens module moves the lens along the optical axis of the lens when autofocusing, and moves the lens along the optical axis perpendicular to the lens when realizing the optical anti-shake function. Since shape memory alloys (shape memory alloys, SMA) are currently the best shape memory materials among shape memory materials, SMA wires are widely used in the field of optical anti-shake. [0003] In order to achieve the anti-shake function of the existing lens module, it is usually nec...
