According to the embodiment of the image capturing module 100 provided by the present application, the image capturing module 100 divides the lens into two groups, namely, the first lens structure 102 and the second lens structure 104 which are stacked, and when light enters the image capturing module 100, the light sequentially passes through the first lens structure 102 and the second lens structure 104 and then is imaged. Specifically, as shown in fig. 3, one or more first lenses 1022 are disposed in the first lens structure 102, as shown in fig. 4, one or more second lenses 1042 are disposed in the second lens structure 104, and after light passes through at least one first lens 1022 in the first lens structure 102, the light passes through at least one second lens 1042 in the second lens structure 104, and finally is injected into the light sensor for imaging.
It should be emphasized that the optical filter 106 is disposed at the other end of the second lens structure 104, i.e. the end far from the first lens structure 102, so as to filter the light with a specific wavelength, thereby greatly improving the imaging quality. Through adopting the split lens structure to integrate the light filter 106 at the other end of second lens structure 104, make light filter 106 fixed connection in the tip or the tip inboard of second lens structure 104, reducible traditional light filter 106's space, thereby make the holistic thickness of camera module 100 obtain the attenuate, and in order to satisfy normal shooting focusing demand, still can set up first lens structure 102 activity, when first lens structure 102 moves to different positions, the relative position between first lens structure 102 and the second lens structure 104 can change, thereby make the whole flexible effect that has of camera module 100.

Further, the method further comprises the following steps: the first magnetic element 1024 is disposed on the first lens structure 102; the second magnetic element 1044 is disposed on the second lens structure 104; wherein at least one of the first magnetic member 1024 and the second magnetic member is magnetically changeable.
In controlling the movement of the first lens structure 102, this is mainly achieved by magnetic adjustment of the first magnetic element 1024 and the second magnetic element. The first magnetic element 1024 is disposed on the first lens structure 102, and the second magnetic element is disposed on the second lens structure 104, so that the control key for the relative position between the first lens structure 102 and the second lens structure 104 can be realized under the action of the first magnetic element 1024 and the second magnetic element by arranging the first magnetic element 1024 and the second magnetic element close to each other. Specifically, by controlling the magnetism of the first magnetic element 1024 and the second magnetic element to be different, the first lens structure 102 can be driven to move to the first position under the action of magnetic attraction force, so that the first lens structure 102 and the second lens structure 104 are mutually attached, in this state, the thickness of the whole camera module 100 is smaller, in the case of photographing by using the camera module 100 normally, the magnetism of the first magnetic element 1024 and the magnetism of the second magnetic element are controlled to be the same, and in the action of repulsive force, the first lens structure 102 is driven to extend outwards, and when moving to the second position, the first lens structure 102 and the second lens structure 104 are arranged at intervals.

Further, as shown in fig. 7, the first magnetic element 1024 and the second magnetic element have different magnetic properties, and the first lens structure 102 moves to the first position, and the first lens structure is attached to the second lens structure; as shown in fig. 8, the first magnetic element 1024 and the second magnetic element have the same magnetic properties, and the first lens structure 102 moves to the second position and is separated from the second lens structure, i.e. a gap exists.
In one particular embodiment, the first magnetic element 1024 and the second magnetic element are both electromagnets.
In another specific embodiment, the first magnetic element 1024 is an electromagnet and the second magnetic element is a permanent magnet.
In another specific embodiment, the first magnetic element 1024 is a permanent magnet and the second magnetic element is an electromagnet.
Further, as shown in fig. 5, the method further includes: the lens carrier 103, the first lens structure 102 is disposed in the lens carrier 103, and the first lens 1022 is disposed at an end of the first lens structure 102 away from the lens carrier 103.
By arranging the lens carrier 103, a certain supporting effect can be achieved on the first lens structure 102, and by arranging the first magnetic element 1024 at one end of the first magnetic element 1024, the position of the lens carrier 103 can be controlled and adjusted under the action of the second magnetic element, so that the requirements of lightness, thinness and photographing can be met. It should be emphasized that the position of the first lens 1022 with respect to the first lens structure 102 is fixed, but in the case of the lens carrier 103 moving up and down, the distance between the first lens 1022 and the second lens 1042 is changed so as to meet the normal shooting requirement.
Wherein, the lens carrier 103 is provided with an opening for transmitting light, and the lens carrier 103 does not shade light, so as to realize normal view finding.
Further, the lens carrier 103 is provided with at least one electromagnetic channel 1032, and the camera module 100 further includes: a plurality of electromagnetic posts 108 are movably disposed within the electromagnetic channels 1032.
By arranging the electromagnetic pillar 108, a certain guiding effect can be achieved on the movement of the first lens structure 102, and meanwhile, the electromagnetic pillar 108 can also achieve the effect of improving the assembly efficiency during assembly. In addition, since the electromagnetic channel 1032 is disposed on the lens carrier 103, the electromagnetic pillar 108 may cooperate with the electromagnetic channel 1032, so that when the first lens structure 102 is driven to extend outwards, that is, when the magnetism of the first magnetic element 1024 and the magnetism of the second magnetic element are the same, the electromagnetic pillar 108 is suspended in the electromagnetic channel 1032, that is, the electromagnetic pillar 108 is not contacted with the inner wall of the electromagnetic channel 1032, friction between the first lens structure 102 and the electromagnetic pillar 108 in the vertical stretching process can be effectively reduced, the process of extending the first lens structure 102 to the second position is faster, abrasion to the electromagnetic pillar 108 and the inner wall of the electromagnetic channel 1032 can be reduced, and the service life is prolonged.
In one embodiment, the electromagnetic channel 1032 is not movable within the lens carrier 103, and the electromagnetic pillar 108 is movable within the electromagnetic channel 1032 to effect movement of the first lens structure relative to the second lens structure during movement.
In another embodiment, the electromagnetic channel 1032 itself is movable relative to the lens carrier 103, and the electromagnetic pillar 108 may act as a guide for movement of the electromagnetic channel 1032.
Further, as shown in fig. 6, the method further includes: the stabilizing support 110 is connected with the second lens structure 104, and the stabilizing support 110 is arranged at one end of the second lens structure 104 far away from the first lens structure 102; wherein the electromagnetic pillar 108 is disposed on the stabilizing support 110, and at least a portion of the electromagnetic pillar 108 extends into the electromagnetic channel 1032.
By arranging the stabilizing support 110 at the other end of the second lens structure 104, i.e. at the end of the second lens structure 104 far away from the first lens structure 102, the shake on the XY plane can be prevented under the action of the stabilizing support 110. It should be emphasized that the electromagnetic pillar 108 is disposed on the stabilizing support 110, so as to provide support for the installation of the electromagnetic pillar 108, and meanwhile, a part of the electromagnetic pillar 108 extends into the electromagnetic channel 1032 to be installed in a complete positioning manner, so that when the first lens structure 102 stretches out and draws back, friction to the inner wall of the electromagnetic channel 1032 is reduced, and the stretching efficiency is improved.
Further, the first magnetic element 1024 and the second magnetic element are both ring-shaped; and/or the first magnetic element 1024 and the second magnetic element 1044 are different in magnetic properties, and the first lens structure 102 moves to the first position; the first magnetic element 1024 and the second magnetic element 1044 have the same magnetic properties, and the first lens structure 102 moves to the second position; the distance between the first lens structure and the second lens structure is smaller than that between the first lens structure and the second lens structure at the first position.
By arranging the first magnetic member 1024 and the second magnetic member in a ring shape, the first magnetic member can be arranged around the first lens 1022 and the second lens 1042, respectively, thereby reducing the light entering influence on the first lens 1022 and the second lens 1042, and on the basis of ensuring the imaging quality, the extension and retraction of the first lens structure 102 relative to the second lens structure 104 can be realized.
It should be emphasized that, since the two magnetic members are annular, the movement of the first lens structure 102 can be made smoother when the first lens structure 102 is controlled to extend from the first position to the second position.
By controlling the magnetism of the first magnetic element 1024 and the second magnetic element 1044 on the basis of using two annular magnetic elements, adjustment of the pitch of the first lens structure relative to the second lens structure can be achieved. Specifically, in the case where the magnetism of the first magnetic member 1024 and the second magnetic member 1044 are different, the first lens structure 102 is moved to the first position, the interval between the two lens structures is smaller, and in the case where the magnetism of the first magnetic member 1024 and the second magnetic member 1044 is the same, the interval between the two lens structures is larger.
Further, the second lens 1042 and the optical filter 106 are of separate structures, the surface of the second lens 1042 near the first lens structure 102 is a curved surface, the surface of the second lens 1042 far away from the first lens structure 102 is a plane, and the optical filter 106 is attached to the surface of the second lens 1042 far away from the first lens structure 102.
By adopting the split structure for the second lens 1042 and the optical filter 106, the second lens 1042 and the optical filter 106 can be processed separately and then connected together secondarily after the processing is completed. It can be appreciated that by adopting a split structure, the structure of the second lens 1042 and the structure of the optical filter 106 can be separately arranged, so that the yield is greatly improved, and the difficulty is reduced for each processing procedure although the mounting procedure is increased, thereby being more convenient for processing.
It should be added that, one side of the second lens 1042 is curved, and the other side is flat for easy assembly with the optical filter 106, so that refraction of the view beam can be achieved under the combined action of the second lens 1042 and the first lens 1022.
It is understood that the material and shape of the second lens 1042 may be the same as or different from the material and shape of the filter 106.
Further, the materials of the second lens 1042 and the optical filter 106 are different, and the second lens 1042 and the optical filter 106 are connected by adhesion.
On the basis of adopting the split second lens 1042 and the optical filter 106, the materials of the split second lens 1042 and the optical filter 106 can be selected to be different materials, so long as the light transmission can be ensured. In addition, the filter 106 may be attached to the second lens 1042 by providing an adhesive connection between the second lens 1042 and the filter 106.
Further, the second lens 1042 and the optical filter 106 are integrally formed.
By directly taking the second lens 1042 and the optical filter 106 as an integral structure, the glass material can be directly molded, and the refraction of light can be realized by the lens with the integral structure, and the effect of filtering light rays with specific wavelengths can be realized.
Further, be equipped with first magnetism spare on the first lens structure, be equipped with the second magnetism spare on the second lens structure to through the magnetism of adjustment first magnetism spare and/or second magnetism spare, with the interval between adjustment first lens structure and the second lens structure, the module of making a video recording still includes: the stable support is arranged at one end of the first lens structure, at least one electromagnetic column is arranged on the stable support, a lens carrier is arranged at one end of the first lens structure, at least one electromagnetic channel is arranged in the lens carrier, the other end of the electromagnetic column is inserted into the electromagnetic channel, the magnetism of the electromagnetic channel is the same as that of the electromagnetic column, and the electromagnetic column is suspended in the electromagnetic channel.

The integrated lens integrated with the second lens 1042 and the optical filter 106 can realize the focal power function and the optical filtering function, so that the second lens 1042 and the optical filter 106 are integrated into an integrated structure, and the height of the lens in the Z direction is reduced.

The second lens structure 104 and the stabilizing support 110 may be adhered together by glue, and the second lens structure 104 is connected to the stabilizing support 110.
The first lens structure 102 and the lens carrier 103 are fixed by glue, and an electromagnetic channel 1032 on the lens carrier 103 is assembled with an electromagnetic column 108 on the stabilizing support 110. When the second lens structure 104 pushes the first lens structure 102 to move through the second magnetic member 1044, the electromagnetic pillar 108 generates electromagnetic force similar to the electromagnetic channel 1032, so that the electromagnetic pillar 108 is suspended in the electromagnetic channel 1032 without friction with the inner wall of the electromagnetic channel 1032. So that the first lens structure 102 pops up quickly. The stable support 110 is adhered to the second lens structure 104 through glue, the stable support 110 is connected with the first lens structure 102 through the electromagnetic column 108 and the lens carrier 103, and therefore the stable support 110 connects the first lens structure 102 with the first lens structure 102, and the stable support 110 drives the first lens structure 102 and the second lens structure 104 to integrally move in the X/Y direction to achieve an anti-shake function.
In the non-working state, the first lens structure 102 and the second lens structure 104 are connected together by the first magnetic element 1024 and the second magnetic element 1044 of the ring-shaped magnet structure on the respective lens barrel structure, so that the height of the camera module in the Z direction can be further reduced.
