The driving assembly comprises a plurality of arch assemblies 50, all the arch assemblies 50 are arranged on the frame body 10 at intervals, each arch assembly 50 comprises an arch body 51 and a shape memory alloy wire 52, the arch body 51 is provided with two elastic arms 5113, the shape memory alloy wire 52 is respectively connected with the two elastic arms 5113, and the shape memory alloy wire 52 contracts after being electrified so as to enable the two elastic arms 5113 to move towards the movable platform 30 and push the movable platform 30 to move along a specified direction. It is understood that the shape memory alloy wire 52 is an alloy wire that can be deformed by contraction when energized, and the contraction speed and degree of the shape memory alloy wire 52 can be controlled by controlling the magnitude of the energizing current.

The suspension mechanism is used for suspending the movable platform 30 in the movable area, when the shape memory alloy wire 52 is not conducted, the movable platform 30 is in the initial state, and the suspension mechanism constantly provides elastic force for respectively resetting the movable platform 30 to the initial state along the X-axis direction and the Y-axis direction.

Referring to fig. 1-5, the arched body of the present embodiment includes two symmetrical arched members 511, each arched member 511 includes a fixing portion 5111, a connecting portion 5112, and an elastic arm 5113, the fixing portion 5111 is mounted on the sidewall of the frame 10, one end of the elastic arm 5112 is connected to the fixing portion 5111, the other end is connected to the connecting portion 5112, and two ends of the shape memory alloy wire 52 are respectively connected to the two connecting portions 5112 of the arched body.

When the shape memory alloy wire 52 of the single bow member 50 is turned on, the shape memory alloy wire 52 is contracted by passing a current, and the shape memory alloy wire 52 simultaneously pulls the two spring arms 5113 to approach each other, so that the included angle between the two spring arms 5113 becomes smaller, which causes the spring arms 5113 to move toward the movable platform 30 and finally pushes the movable platform 30 to move along the positive direction or the negative direction of the X-axis/Y-axis.

Taking the arcuate member 50 disposed along the positive X-axis direction of the movable platform 30 as an example, when the shape memory alloy wire 52 is energized, the shape memory alloy wire 52 is contracted by passing current through the shape memory alloy wire 52, and the shape memory alloy wire 52 simultaneously pulls the two elastic arms 5113 to approach each other, so that the included angle between the two elastic arms 5113 becomes smaller, which causes the elastic arms 5113 to move toward the movable platform 30 and finally pushes the movable platform 30 to move along the negative X-axis direction, so as to actively correct the shake of the movable platform 30 in the negative X-axis direction. Specifically, the shake correction of the image sensor 40 in the X-Y plane is controlled by controlling the amount of current flowing through the shape memory alloy wire 52 to control the moving distance of the moving platform 30.

It should be noted that the contraction speed and the degree of contraction of the shape memory alloy wire 52 are related to the magnitude of the flowing current, as well as the parameters of the shape memory alloy wire 52 such as the alloy material, the thickness, etc., and the type, the diameter and the magnitude of the flowing current of the shape memory alloy wire 52 are set according to the actual requirements, so that the generated acting force can meet the actual requirements.

When the arched member 511 pushes the movable platform 30 to move along the positive X-axis direction/negative X-axis direction/positive Y-axis direction/negative Y-axis direction, the elastic force of the suspension spring 60 corresponding to the axis direction needs to be overcome, and the elastic force is used to limit the moving speed and moving distance of the movable platform 30 along the positive X-axis direction/negative X-axis direction/positive Y-axis direction/negative Y-axis direction, so as to avoid the damage to the image sensor 40 and the shaking failure caused by too fast movement and over-limit movement, thereby effectively improving the reliability of shaking prevention.
