The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
The camera module 100 according to an embodiment of the present application is described below with reference to fig. 1 to 5.
As shown in fig. 1, according to the camera module 100 of the first aspect of the present application, the camera module 100 is used in an electronic apparatus 1000, the camera module 100 can be retracted into a housing 3 of the electronic apparatus 1000 and a portion of the camera module 100 can be extended out of the housing 3 of the electronic apparatus 1000, and the camera module 100 includes: a light sensing element 1 and a lens assembly.
The photosensitive element 1 is located at one axial side of the lens assembly, the lens assembly includes a plurality of sets of coaxially arranged lens groups 2, each set of lens groups 2 includes at least one lens 20, for example, each set of lens groups 2 may include only one lens 20, each set of lens groups 2 may also include a plurality of lenses 20, or one part of lens groups 2 includes only one lens 20 and another part of lens groups 2 includes a plurality of lenses 20.
The lens group 2 farthest from the photosensitive element 1 is an outer lens group 2, and the outer lens group 2 is movable in the axial direction of the lens assembly with respect to the housing 3 of the electronic apparatus 1000. Therefore, the total lens length of the camera module 100 can be changed through the movement of the outer lens group 2, so that the whole volume of the camera module 100 can be changed; and by the movement of the outer lens group 2, the focal length can also be changed, which is an outer zoom mode.
At least one of the other lens groups 2 of the plurality of lens groups 2 excluding the outer lens group 2 is movable in the axial direction of the lens assembly with respect to the housing 3 of the electronic apparatus 1000, for example, one of the other lens groups 2 excluding the outer lens group 2 of the plurality of lens groups 2 is movable in the axial direction of the lens assembly with respect to the housing 3 of the electronic apparatus 1000, a part of the other lens groups 2 excluding the outer lens group 2 of the plurality of lens groups 2 is movable in the axial direction of the lens assembly with respect to the housing 3 of the electronic apparatus 1000, or each of the other lens groups 2 excluding the outer lens group 2 of the plurality of lens groups 2 is movable in the axial direction of the lens assembly with respect to the housing 3 of the electronic apparatus 1000. The setting can adjust and change the focal length, when the focal length is changed in an external zooming mode, the total length of the lens is also changed, so that the total length of the lens can be further changed, and the whole volume of the camera module 100 can be further changed; when the focal length is changed by means of inner zooming, the total length of the lens is unchanged.
Therefore, by moving the lens group 2 relative to the housing 3 of the electronic device 1000, not only the total lens length can be changed, the volume of the camera module 100 can be changed, and the focal length can be adjusted, but also the camera module 100 can be retracted into the housing 3 of the electronic device 1000 or a part of the camera module 100 can be extended out of the housing 3 of the electronic device 1000.
When the camera module 100 works, the camera module 100 can be adjusted to a working state by moving the outer lens group 2 and removing the movable lens group 2 in the other lens group 2 of the outer lens group 2, at this time, a part of the camera module 100 extends out of the shell 3 of the electronic device 1000, at this time, external light can sequentially pass through the plurality of lens groups 2 and enter the photosensitive element 1, and the photosensitive element 1 captures the light to form an image. In this process, zooming may also be achieved by adjusting and moving the outer lens group 2, zooming may also be achieved by adjusting and moving the movable lens group 2 in the other lens group 2 excluding the outer lens group 2, or zooming may also be achieved by adjusting and moving the outer lens group 2 in conjunction with adjusting and moving the movable lens group 2 in the other lens group 2 excluding the outer lens group 2.
When the camera module 100 does not work, the outer lens group 2 can be moved towards the direction adjacent to the photosensitive element 1 by moving the outer lens group 2, so that the total length of the lens is reduced, and the whole volume of the camera module 100 can be reduced; alternatively, when the camera module 100 does not operate, the total lens length can be reduced by moving the outer lens group 2 and the movable lens groups 2 in the other lens groups 2 excluding the outer lens group 2 so that the outer lens group 2 and the movable lens groups 2 in the other lens groups 2 excluding the outer lens group 2 move toward the direction adjacent to the photosensitive element 1, so that the overall volume of the camera module 100 can be reduced. At this time, the whole camera module 100 may be retracted into the housing 3 of the electronic device 1000, so that when the camera module 100 does not operate, the electronic device 1000 has a compact and beautiful overall structure, and a lens of the camera module 100 is prevented from protruding out of the housing 3 of the electronic device 1000 to cause large abrasion.
From this, when camera module 100 is out of work for camera module 100's total lens length reduces, thereby makes camera module 100's whole volume reduce, is favorable to camera module 100's miniaturization, reduces the space that camera module 100 took when out of work. When the camera module 100 is used for equipment such as a mobile phone, the total length of the lens of the camera module 100 can be reduced when the camera module 100 does not work, and the camera module 100 can be retracted to reduce the thickness of the whole machine, so that the whole machine is light and thin, and the occupied space of the camera module 100 is reduced, so that the whole machine is favorable for placing other devices.
According to the camera module 100 of the embodiment of the application, owing to be equipped with the coaxial battery of lens 2 of multiunit, and outer lens group 2 is portable along the axial of lens subassembly, can make camera module 100's whole volume adjustable, when camera module 100 is out of work, can reduce camera module 100's camera lens overall length, thereby can reduce camera module 100's whole volume, make camera module 100's whole miniaturization more, reduce camera module 100 occupation space, when being used for this camera module 100 the complete machine, be favorable to reducing the thickness of complete machine, thereby be favorable to the frivolousness of complete machine, and be favorable to putting of other devices in the complete machine. In addition, zooming can be conveniently achieved by movement of the lens group 2.
According to some embodiments of the present application, referring to fig. 1-2, the camera module 100 includes: a first barrel 21 and a second barrel 22. The other lens groups 2 of the plurality of lens groups 2 excluding the outer lens group 2 are disposed in the first barrel 21, and the outer lens group 2 is disposed in the second barrel 22. The second barrel 22 is movably disposed on the first barrel 21 along the axial direction of the first barrel 21, and the second barrel 22 moves to drive the outer lens group 2 to extend out of and retract into the first barrel 21, so that the movement of the outer lens group 2 can be conveniently achieved, and the total lens length and the overall size of the camera module 100 can be conveniently changed. For example, when the camera module 100 is operated, the second barrel 22 may be controlled to move so that at least a portion of the second barrel 22 extends out of the first barrel 21, so that the camera module 100 may be adjusted to an operating state, and external zooming may be achieved by adjusting and moving the second barrel 22, or internal zooming may be achieved by adjusting and moving the movable lens group 2 in the other lens groups 2 excluding the outer lens group 2 in the first barrel 21; when the camera module 100 does not work, the second barrel 22 can be controlled to move so that at least a part of the second barrel 22 is retracted into the first barrel 21, thereby reducing the total lens length of the camera module 100 and reducing the overall volume of the camera module 100.
For example, in the example of fig. 1-2, the lens assembly includes four sets of coaxially disposed lens groups 2, each set of lens groups 2 includes one lens 20, wherein the lens group 2 farthest from the photosensitive element 1 is an outer lens group 2, the outer lens group 2 is located in a second barrel 22, the remaining three sets of lens groups 2 are located in the first barrel 21, and each set of lens groups 2 located in the first barrel 21 are movable along the axial direction of the lens assembly, and the second barrel 22 is movably disposed in the first barrel 21 along the axial direction of the first barrel 21.
According to some embodiments of the present application, referring to fig. 3-4, each group of lens groups 2 is movable in an axial direction of the lens assembly. Therefore, the total lens length, the whole volume and the focal length of the camera module 100 can be adjusted more flexibly by moving the lens group 2 along the axial direction of the lens component. For example, when the camera module 100 is in the working state, the camera module 100 can be adjusted to the working state by adjusting and moving at least a part of the lens group 2, and the focal length can be changed by adjusting and moving at least a part of the lens group 2, so that the adjustment of the working state of the camera module 100 is more flexible and diversified; when the camera module 100 does not work, each group of lens groups 2 can be moved through adjustment, so that each group of lens groups 2 moves towards the direction adjacent to the photosensitive element 1, the distance between the adjacent lens groups 2 is reduced, the total length of the lens can be reduced to a greater extent, the whole volume of the camera module 100 can be reduced to a greater extent, the whole body of the camera module 100 is more miniaturized, the occupied space of the camera module 100 is further reduced, when the camera module 100 is used for a whole machine, the thickness of the whole machine can be reduced, the whole machine can be lightened and thinned, and the placement of other devices in the whole machine can be facilitated.
In some alternative embodiments of the present application, the at least one lens group 2 comprises a plurality of lenses 20, and each lens 20 of the lens group 2 comprising the plurality of lenses 20 is movable in an axial direction of the lens assembly. Therefore, the interval between each group of lens groups 2 and the interval between each lens 20 in at least one lens group 2 can be compressed, so that the camera module 100 can be in an inoperative state, the total lens length of the camera module 100 can be shorter, and the whole camera module 100 is more miniaturized. When the camera module 100 is in operation, the lens group 2 and the lens 20 can be adjusted to adjust the camera module 100 to an operating state.
According to some alternative embodiments of the present application, referring to fig. 3 to 5, the camera module 100 includes a plurality of lens barrels 23 arranged in an axial direction of the lens assembly, one of adjacent two lens barrels 23 is movable relative to the other in the axial direction of the lens assembly, so that one of the adjacent two lens barrels 23 can be extended and retracted into the other, by moving the lens barrel 23 of the adjacent two lens barrels 23 away from the photosensitive element 1, at least a part of the lens barrel 23 can extend out of the other lens barrel 23 and at least a part of the lens barrel 23 can be accommodated in the other lens barrel 23, the number of the lens barrels 23 is the same as that of the lens groups 2, and the lens groups 2 are arranged in the corresponding lens barrel 23, and when each lens barrel 23 moves, the lens groups 2 in the lens barrel 23 and the lens barrel 23 on the side of the lens barrel 23 far away from the photosensitive element 1 can be driven to move. Since the plurality of lens barrels 23 are arranged in the axial direction of the lens barrel assembly, one of the adjacent lens barrels 23 can move relative to the other lens barrel in the axial direction of the lens barrel assembly, so that one of the adjacent lens barrels 23 can extend out and retract into the other lens barrel, thereby reducing the length of the lens assembly in the axial direction and further shortening the total lens length of the camera module 100. When the camera module 100 works, at least one of the lens barrels 23 can be moved to adjust the camera module 100 to a working state, and zooming can be realized by adjusting and moving at least one of the lens barrels 23, and as any one of the lens barrels 23 is moved, the total length of the lens can be changed, and external zooming can be realized by moving any one of the lens barrels 23; when the camera module 100 does not work, each lens barrel 23 can be moved, so that each lens barrel 23 moves towards the direction adjacent to the photosensitive element 1, the distance between the adjacent lens groups 2 can be shortened, the size of the camera module 100 can be reduced when the camera module does not work, and the occupied space is reduced.
For example, in the example of fig. 3 to 5, the lens assembly includes four groups of lens groups 2, the camera module 100 includes four lens barrels 23, one lens group 2 is disposed in each lens barrel 23, the four lens barrels 23 are coaxially arranged along the axial direction, and the lens barrel 23 far away from the photosensitive element 1 in two adjacent lens barrels 23 is movable along the axial direction, so that the lens barrel 23 can extend out or retract into the other lens barrel 23 in two adjacent lens barrels.
According to some embodiments of the present application, referring to fig. 1 to 5, the camera module 100 has a compression state and an operating state, and the total lens length of the camera module 100 is L when the camera module 100 is in the compression state1When the camera module 100 is in the working state, the total lens length of the camera module 100 is L2，L2、L1Satisfies the following conditions: l is1＜L2. From this, when the camera was out of work, can be so that camera module 100 is in compression state for the total length of the camera lens when camera module 100 was out of work shortens, and thus the volume is littleer. When the camera module 100 is in a compressed state, the distance between at least one group of adjacent lens groups 2 is smaller than the distance between the corresponding adjacent lens groups 2 when the camera module 100 is in an operating state.
According to some alternative embodiments of the present application, referring to fig. 1-5, the distance between adjacent lens groups 2 is d when camera module 100 is in a compressed state1When the camera module 100 is in an operating state, the distance between the adjacent lens groups 2 is d2，d1、d2Satisfies the following conditions: d1≤0.9d2. Therefore, when the camera does not work, the camera can be used for shootingThe camera module 100 is in a compressed state, so that the total lens length of the camera module 100 when not in operation is effectively shortened, and the volume is smaller.
It should be noted that the comparison of the pitches between the adjacent lens groups 2 when the camera module 100 is in the operating state and in the compressed state refers to the comparison of the pitches between the corresponding adjacent lens groups 2.
According to some alternative embodiments of the present application, referring to fig. 1 and 3, when the camera module 100 is in a compressed state, the distance between adjacent lens groups 2 is not greater than 0.15 mm. Therefore, when the camera module 100 is in the compressed state, the total length of the lens barrel can be effectively shortened, and the volume of the camera module 100 in the compressed state can be effectively reduced.
According to some alternative embodiments of the present application, at least one group of lens groups 2 comprises a plurality of lenses 20, and when camera module 100 is in a compressed state, a spacing between adjacent lenses 20 in the group of lens groups 2 comprising the plurality of lenses 20 is not greater than 0.15 mm. Therefore, when the camera module 100 is in the compressed state, by limiting the distance between the adjacent lens groups 2 and the distance between the adjacent lenses 20, the total lens length can be further effectively shortened, and the volume of the camera module 100 in the compressed state can be further effectively reduced.
