The invention discloses a lens module and camera equipment with the same; the lens module comprises a lens barrel, a movable part and a driving assembly, and an accommodating space is arranged in the lens barrel; the movable part is used for bearing an image sensor, and the part, used for bearing the image sensor, of the movable part is located below the accommodating space; the driving assembly comprises an elastic arm and a memory alloy wire, the elastic arm comprises a fixed end and a free end, the free end abuts against the movable part, one end of the memory alloy wire is fixedly arranged, and the other end of the memory alloy wire is connected with the elastic arm; and the memory alloy wire is electrified and contracted to drive the elastic arm to rotate, so that the free end drives the movable part to move. According to the embodiment of the invention, the lens module is low in cost, simple in structure and small in occupied space, and facilitates the reduction of the size of camera equipment.
Description
technical field [0001] The invention relates to the field of imaging technology, in particular to a lens module and an imaging device having the same. Background technique [0002] With the rapid development of multimedia technology, digital cameras, video cameras, tablet computers and mobile phones with cameras are more and more popular among consumers. In digital cameras, video cameras and mobile phone cameras and other photographic devices, lens modules are an indispensable parts. A camera module usually includes a lens barrel, a lens mount, a lens and an image sensor. The lens is accommodated in the lens barrel, and the image sensor is arranged in the lens holder. [0003] The existing focusing lens module utilizes a driving motor or a voice coil motor to drive the lens barrel or the lens base to be displaced so as to change the distance between the lens barrel and the lens base of the lens module to achieve focusing or anti-shake. However, such a lens module is not o...
