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. Preferably, one end of the elastic arm 5113 away from the fixing portion 5111 is extended and bent to form a transition portion 51131 for fixing the connecting portion 5112, so as to reduce the distance from the connecting portion 5112 to the movable platform 30, so that the shape memory alloy wire 52 provides a smaller deformation driving force to effectively drive the movable platform 30.

Preferably, the frame 10 is rectangular, the driving assembly includes four bow assemblies 50, the bow assemblies 50 are respectively disposed on four sides of the frame 10, one of the four bow assemblies 50 is used for pushing the movable platform 30 to move along the positive direction of the X axis, the other is used for pushing the movable platform 30 to move along the negative direction of the X axis, the other is used for pushing the movable platform 30 to move along the positive direction of the Y axis, and the other is used for pushing the movable platform 30 to move along the negative direction of the Y axis. Through the above arrangement, the movable platform 30 can receive the driving force in the positive direction of the X axis, the negative direction of the X axis, the positive direction of the Y axis and the negative direction of the Y axis, so that the shaking directional movement of the movable platform 30 in the positive direction of the X axis, the negative direction of the X axis, the positive direction of the Y axis and the negative direction of the Y axis is realized
When the shape memory alloy wire 52 of the single bow assembly 50 is turned on, the shape memory alloy wire 52 is contracted by flowing a current, 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 towards 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 assembly 50 disposed along the positive X-axis of the movable platform 30 as an example, when the shape memory alloy wire 52 is energized, the shape memory alloy wire 52 contracts when current flows 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 towards the movable platform 30 and finally pushes the movable platform 30 to move along the negative X-axis direction, thereby actively calibrating the shaking 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 stage 30.

It should be noted that the contraction speed and the contraction degree 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 and the like, 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.
