In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1 to fig. 2, a zoom lens 100 according to an embodiment of the present disclosure will be described. Zoom lens 100 includes: a voice coil motor stator 10, a voice coil motor mover 20, and a resilient support structure 30.
Specifically, voice coil motor mover 20 is disposed in voice coil motor stator 10, a light passing hole 21 is disposed in voice coil motor mover 20, a zoom lens 22 is disposed in light passing hole 21, and elastic support structure 30 is connected to voice coil motor stator 10 and voice coil motor mover 20 at the same time, and is used for guiding motor mover 20 to move along the axial direction of motor stator 10.
When the voice coil motor mover 20 is energized in the magnetic field of the voice coil motor stator 10, the voice coil motor mover 20 can drive the zoom lens 22 to reciprocate.
It will be appreciated that the voice coil motor stator 10 is capable of emitting a steady magnetic field and the voice coil motor mover 20 is positioned within the magnetic field emitted by the voice coil motor stator 10. When the voice coil motor mover 20 is not energized, since the elastic support structure 30 is simultaneously connected to the voice coil motor stator 10 and the voice coil motor mover 20, the elastic support structure 30 can maintain an initial state with the voice coil motor stator 10 and the voice coil motor mover 20.
When the voice coil motor mover 20 is energized in the magnetic field of the voice coil motor stator 10, according to the ampere force principle, the energized voice coil motor mover 20 is subjected to an inductive force in the magnetic field of the voice coil motor stator 10, the inductive force can drive the voice coil motor mover 20 to axially move in the voice coil motor stator 10, at this time, the zoom lens 22 and the voice coil motor mover 20 move synchronously, and the elastic support structure 30 deforms. Meanwhile, the elastic support structure 30 can guide the motor mover 20 to move along the axial direction of the motor stator 10, so as to perform a guiding function.
When opposite currents are conducted to the voice coil motor mover 20 and then go backward, according to the ampere force principle, when the currents are opposite, the directions of the induced forces applied to the voice coil motor mover 20 in the magnetic field of the voice coil motor stator 10 after being electrified are also opposite. Therefore, the induced force may drive the voice coil motor mover 20 to move in the reverse direction in the voice coil motor stator 10. Meanwhile, the elastic supporting structure 30 releases elastic potential energy to synchronously push the voice coil motor mover 20 to move reversely in the voice coil motor stator 10, so that the voice coil motor mover 20 rebounds rapidly, the zoom lens 22 also moves reversely with the voice coil motor mover 20, and when light enters the zoom lens 22 in the light through hole 21, the focal length of the light also changes.
Compared with the traditional lens, the zoom lens 100 has the advantages that the zoom lens 22 is arranged in the light through hole 21 of the voice coil motor mover 20, and the zoom lens 22 is driven to axially move by the induced force applied to the voice coil motor mover 20, so that the structure is simplified, and the size and the weight are reduced. Meanwhile, the elastic supporting structure 30 can accelerate the resetting of the voice coil motor mover 20 and the zoom lens 22, so that the zooming speed is improved, and meanwhile, the elastic supporting structure 30 can also reduce the radial vibration of the voice coil motor mover 20, thereby being beneficial to improving the stability during zooming.
It should be added that the magnitude of the focal length change of the zoom lens 100 can also be adjusted by changing the magnitude of the current flowing into the voice coil motor mover 20. According to the ampere force principle, the magnitude of the inductive force received by the magnetic field of the voice coil motor mover 20 is proportional to the magnitude of the current passing through the voice coil motor mover 20. Therefore, the larger the current passing through the voice coil motor mover 20 is, the larger the voice coil motor mover 20 can work against the elastic potential energy of the elastic support structure 30, the larger the axial movement distance of the voice coil motor mover 20 is, and the larger the focal length change of the zoom lens 100 is; conversely, the smaller the current passing through the voice coil motor mover 20 is, the smaller the voice coil motor mover 20 can work against the elastic potential energy of the elastic support structure 30, the smaller the axial movement distance of the voice coil motor mover 20 is, and the smaller the focal length change of the zoom lens 100 is.
The number of the elastic supporting structures 30 may be two, the two elastic supporting structures 30 are respectively disposed at the head end and the tail end of the zoom lens 100, and the voice coil motor stator 10 and the voice coil motor mover 20 are simultaneously connected through the pair of elastic supporting structures 30, so that the zooming speed and stability of the zoom lens 100 can be further improved.
The application provides a zoom lens 100 compares with prior art, through the electromagnetic induction control zoom lens 22's that produces between voice coil motor stator 10 and the voice coil motor active cell 20 axial displacement, and elastic support structure 30 is connected with voice coil motor stator 10 and voice coil motor active cell 20 simultaneously, and is right voice coil motor active cell 20's motion plays the guide effect, has both simplified overall structure, reduces volume and weight, can accelerate voice coil motor active cell 20 again and zoom lens 22 and reset, improves the speed of zooming, stability when keeping zooming.

It can be understood that, since the first fixing plate 311 is fixedly connected to the voice coil motor stator 10 and the second fixing plate 312 is fixedly connected to the voice coil motor mover 20, when the induced force drives the voice coil motor mover 20 to axially move in the voice coil motor stator 10, the voice coil motor mover 20 can drive the second fixing plate 312 to synchronously axially move. Since both ends of the connection piece 313 are fixedly connected to the first fixing piece 311 and the second fixing piece 312, respectively, the connection piece 313 is elastically deformed. When opposite currents are conducted to the voice coil motor mover 20 and go backwards, the connecting piece 313 releases elastic potential energy to push the voice coil motor mover 20 to move reversely, so that the voice coil motor mover 20 rebounds rapidly, the zoom lens 22 resets along with the voice coil motor mover 20, and the zoom speed is improved.
