It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The technical scheme disclosed by the embodiment of the application is described in detail below with reference to the accompanying drawings.
In order to solve the technical problem that the height dimension of the camera is thickened by the iris diaphragm in the related art, the embodiment of the application provides a lens module. As shown in fig. 1 to 9, the lens module disclosed in the embodiment of the application includes a lens barrel 100, a lens set 200, an iris diaphragm 300 and a driving device 400.
The lens barrel 100 is a basic component of the lens module, provides a mounting base for the lens group 200, the iris diaphragm 300 and the driving device 400, and plays a role in protection.
As shown in fig. 2 to 4 and 7, the lens barrel 100 has a light inlet and a receiving cavity, the light inlet is communicated with the receiving cavity, and the lens set 200 is disposed in the receiving cavity. The accommodating cavity provides an installation space for the lens group 200, and the light inlet communicates the accommodating cavity with the outside, so that light can enter the accommodating cavity through the light inlet, and the lens group 200 performs light distribution, so that functions of eliminating chromatic aberration, aberration and the like are realized, and a camera can acquire high-quality images.
The iris diaphragm 300 is mounted on the lens barrel 100, and the iris diaphragm 300 is located at a side of the lens barrel 100 where the light inlet is provided. It should be understood that the iris diaphragm 300 can adjust the light passing area by changing the aperture size of the diaphragm aperture, so as to control the light flux transmitted from the light inlet aperture to the lens set 200, so that the iris diaphragm 300 can be adapted under different light environments and different shooting requirements. With this arrangement, the iris diaphragm 300 can be adjusted before the light is projected onto the lens set 200, so as to adaptively adjust the light flux introduced from the light inlet.
In the related art, the iris diaphragm and the lens module are two independent structures, and the iris diaphragm and the lens module are overlapped inside the camera, so that the overall size of the camera is larger, and the convex hull problem is particularly shown on the electronic equipment.
In the embodiment of the application, the lens set 200 has a protrusion 211, and the protrusion 211 is convexly disposed in the iris diaphragm 300. It should be understood that the lens assembly 200 includes a convex lens on a side near the light entrance, and the convex portion 211 is referred to as the convex side of the convex lens. Under this structural layout, the protruding portion 211 can extend towards the light inlet side into the aperture hole of the iris 300, and the aperture hole can avoid the protruding portion 211 and provide a receiving space for the protruding portion 211, and at this time, the lens group 200 is partially embedded in the iris 300, which corresponds to the height direction of the lens module.
It should be noted that, in the embodiment of the present application, the iris diaphragm 300 is set as a part of the lens module, and the lens group 200 and the iris diaphragm 300 have a partially-structured embedding relationship inside the lens module, so that the iris diaphragm 300 and the lens group 200 share the same carrier, i.e. the lens barrel 100, and the overall structural compactness of the lens module can be improved. Compared with the scheme that the iris diaphragm and the lens module are respectively and independently arranged in the related art, the height dimension of the lens module is reduced, so that the height dimension of the camera can be reduced, and the convex hull problem of the electronic equipment is improved.
Meanwhile, the driving device 400 is connected to the iris diaphragm 300, and the driving device 400 is used to adjust the size of the diaphragm aperture of the iris diaphragm 300. When the iris diaphragm 300 needs to be adjusted, convenient adjustment and control can be realized through the driving device 400, so that the operation convenience can be improved.
In order to further play a role in protection, the lens module may further include a protection cover 600, where the protection cover 600 is disposed on a side of the lens module near the light inlet. Of course, the protection cover 600 needs to be provided with a light-passing hole so as to facilitate light passing.
As can be seen from the above description, in the embodiment of the present application, the iris diaphragm is mounted on the side of the lens barrel where the light inlet is provided, and the protruding portion of the lens group is protruding into the iris diaphragm, that is, the protruding portion of the lens group facing the light inlet extends into the aperture hole of the iris diaphragm.
In the embodiment of the present application, the specific implementation that the protruding portion 211 protrudes into the iris diaphragm 300 is not limited, for example, by thinning the side of the lens barrel 100 where the light inlet is provided, when the iris diaphragm 300 is mounted on the lens barrel 100, the height position of the iris diaphragm 300 is reduced and is sleeved around the protruding portion 211, that is, the protruding portion 211 is located in the aperture hole of the iris diaphragm 300, and at this time, the overall height dimension of the lens module is necessarily reduced.
In another embodiment, as shown in fig. 2 to 4, the lens barrel 100 of the embodiment of the application may be provided with a first step groove 111 on the light entrance side, the first step groove 111 is disposed around the light entrance, and the iris diaphragm 300 is disposed in the first step groove 111. It should be appreciated that since the first stepped groove 111 is disposed around the light entrance such that the first stepped groove 111 is arranged stepwise with the opening of the light entrance, when the iris diaphragm 300 is disposed within the first stepped groove 111, it is ensured that the iris diaphragm 300 is also disposed around the light entrance so as to control the light flux projected by the light entrance to the lens group 200 through the iris diaphragm 300.
Meanwhile, since the iris diaphragm 300 is disposed in the first stepped groove 111, the first stepped groove 111 provides a receiving space for the iris diaphragm 300, and the iris diaphragm 300 is correspondingly embedded in the lens barrel 100, so that only the size space of the lens module needs to be occupied after the iris diaphragm 300 and the lens module are combined.
In order to further optimize the compactness of the lens module, as shown in fig. 3, the protrusion 211 of the embodiment of the present application may protrude from the top surface of the iris diaphragm 300. It should be understood that the top surface of the iris diaphragm 300 refers to the end surface of the iris diaphragm facing away from the lens barrel. With this structural arrangement, the boss 211 is configured to have more portion extending into the aperture of the iris 300 until the end of the boss 211 protrudes beyond the top surface of the iris 300, at which time the height dimension of the lens module is reduced to a minimum.
Meanwhile, the protruding portion 211 protrudes from the top surface of the iris diaphragm 300 in the surrounding area, so that a receiving space can be provided for other components, such as the protection cover 600 and the stop ring 500 described below, which can be disposed around the protruding portion 211, thereby avoiding increasing the height of the lens module.
In the embodiment of the present application, the type of the iris diaphragm 300 may be various, for example, the iris diaphragm 300 is a deformed structural member, which can change the size of the diaphragm aperture in the middle thereof by deforming. In another embodiment, as shown in fig. 2 to 7, the iris diaphragm 300 of the embodiment of the application may include a first blade 310 and a second blade 320, where the first blade 310 and/or the second blade 320 are movably disposed in the first stepped groove 111 and are stacked along the optical axis direction of the lens module, the first blade 310 is provided with a first through hole 311, the second blade 320 is provided with a second through hole 321, and the driving device 400 is used for driving the first blade 310 and the second blade 320 to generate a relative motion so as to change the size of the aperture of the diaphragm.
Specifically, in the embodiment of the present application, at least one of the first vane 310 and the second vane 320 is movably disposed in the first stepped groove 111, that is, the first vane 310 or the second vane 320 is movably disposed in the first stepped groove 111, or both the first vane 310 and the second vane 320 are movably disposed in the first stepped groove 111. Meanwhile, since the first blade 310 and the second blade 320 are stacked along the optical axis direction of the lens module, only the overlapping area of the first through hole 311 and the second through hole 321 can smoothly pass light, and the overlapping area of the first through hole 311 and the second through hole 321 defines the light transmission hole of the iris 300.
Under the driving action of the driving device 400, when the first blade 310 and the second blade 320 can generate relative motion, the relative positions of the first through hole 311 and the second through hole 321 will also change, so that the overlapping area of the first through hole 311 and the second through hole 321 can be adjusted, and the size of the diaphragm aperture of the iris diaphragm 300 can be further changed.
It should be noted that, the iris diaphragm 300 of the embodiment of the present application is not provided with a housing, which is equivalent to that the iris diaphragm 300, the lens set 200 and the driving device 400 all use the lens barrel 100 as the carrier, so that the overall occupied volume of the iris diaphragm 300 can be definitely reduced, and the structural compactness of the lens module is further improved, so as to achieve the effect of further reducing the height dimension of the camera.
Further, as shown in fig. 2, 5 and 6, the first through hole 311 of the embodiment of the present application may include a first light transmitting portion 311a and a second light transmitting portion 311b which are connected, the area of the first light transmitting portion 311a is smaller than the area of the second light transmitting portion 311b, the second through hole 321 includes a third light transmitting portion 321a and a fourth light transmitting portion 321b which are connected, the area of the third light transmitting portion 321a is smaller than the area of the fourth light transmitting portion 321b, the iris diaphragm 300 has a first state and a second state, the first light transmitting portion 311a and the third light transmitting portion 321a overlap to form a small aperture light transmitting area H1 when the iris diaphragm 300 is in the first state, and the second light transmitting portion 311b and the fourth light transmitting portion 321b overlap to form a large aperture light transmitting area H2 when the iris diaphragm 300 is in the second state.
Under such a structural layout, due to the size relationship of the dimensions, the first light transmitting portion 311a and the second light transmitting portion 311b are more convenient to form the small aperture light transmitting region H1 when they are overlapped, and the second light transmitting portion 311b and the fourth light transmitting portion 321b are more convenient to form the large aperture light transmitting region H2 when they are overlapped. By the driving action of the driving device 400, the first blade 310 and the second blade 320 can be driven to generate relative motion, so that the iris diaphragm 300 is switched between the first state and the second state. When a smaller light quantity is required, the variable aperture 300 can be switched to a first state and the light is transmitted by the small aperture light transmission area H1, and when a larger light quantity is required, the variable aperture 300 can be switched to a second state and the light is transmitted by the large aperture light transmission area H2.
In the embodiment of the present application, the specific shapes of the first through hole 311 and the second through hole 321 are not limited, for example, the first light-transmitting portion 311a, the second light-transmitting portion 311b, the third light-transmitting portion 321a and the fourth light-transmitting portion 321b may be square holes, so that the small aperture light-transmitting area H1 and the large aperture light-transmitting area H2 are square light-transmitting areas. In another embodiment, as shown in fig. 2, 5 and 6, the hole edges of the first through hole 311 and the second through hole 321 in the embodiment of the present application may be circular, so that the small aperture transparent area H1 and the large aperture transparent area H2 are circular transparent areas.
It should be understood that, when the iris diaphragm 300 is switched to the first state, the hole edges of the first light transmitting portion 311a, the second light transmitting portion 311b, the third light transmitting portion 321a and the fourth light transmitting portion 321b are all circular arcs, and when the iris diaphragm 300 is switched to the first state, the hole edges of the first light transmitting portion 311a and the third light transmitting portion 321a are mostly overlapped to form a circular light transmitting area, and the aperture of the circular light transmitting area is smaller, so that the aperture of the circular light transmitting area is a small aperture light transmitting area H1, as can be seen in fig. 5, and when the iris diaphragm 300 is switched to the second state, the hole edges of the second light transmitting portion 311b and the fourth light transmitting portion 321b are mostly overlapped to form a circular light transmitting area, and when the aperture of the circular light transmitting area is larger, the aperture of the circular light transmitting area is a large aperture light transmitting area H2, as can be seen in fig. 6.
In an alternative solution, as shown in fig. 2 and fig. 5 to fig. 7, the iris diaphragm 300 of the embodiment of the application may further include a third blade 330 and a fourth blade 340, where the third blade 330 and the fourth blade 340 are positioned and installed in the first stepped groove 111, the first blade 310 and the second blade 320 are disposed between the third blade 330 and the fourth blade 340, the third blade 330 is provided with a third through hole 331, the fourth blade 340 is provided with a fourth through hole 341, the third through hole 331 and the fourth through hole 341 have the same shape, and central axes of the third through hole 331 and the fourth through hole 341 are located on an optical axis of the lens module, and the third through hole 331 and the fourth through hole 341 are used for passing light in a superposition area of the first through hole 311 and the second through hole 321.
It should be understood that the fourth blade 340 is a bottom blade of the iris diaphragm 300, and can support other blades, and meanwhile, the fourth through hole 341 can block the light outside the overlapping area of the first through hole 311 and the second through hole 321 by the light in the overlapping area of the first through hole 311 and the second through hole 321, so as to avoid stray light formed in the accommodating cavity to affect the image quality. The third blade 330 is a top blade of the iris diaphragm 300, and the third through hole 331 can also block light outside the overlapping area of the first through hole 311 and the second through hole 321 to avoid stray light formed in the accommodating cavity to affect the image quality, and meanwhile, the third blade 330 can also cover and shield the first blade 310 and the second blade 320 to avoid appearance defects caused by direct exposure of the first blade 310 and the second blade 320.
The embodiment of the application is not limited to the specific positioning and mounting manner of the third blade 330 and the fourth blade 340, for example, the lens barrel 100 is provided with a plurality of positioning protrusions 114 in the first step groove 111, the third blade 330 is provided with a third through hole 331, the fourth blade 340 is provided with a fourth through hole 341, the third through hole 331 can be in positioning fit with the positioning protrusion 114, the fourth through hole 341 can be in positioning fit with the positioning protrusion 114, and particularly, see fig. 2 and 7, of course, the lens barrel 100 can be provided with positioning recesses in the first step groove 111, and the third blade 330 and the fourth blade 340 can be provided with protrusion structures engaged with the positioning recesses, thereby realizing positioning fit.
In an embodiment of the present application, there may be various relative movement modes of the first blade 310 and the second blade 320, for example, at least one of the first blade 310 and the second blade 320 is configured to be movable toward the other, so that the size of the aperture of the iris diaphragm 300 may be adjusted by the relative movement of the first blade 310 and the second blade 320.
In another embodiment, as shown in fig. 2 to 6, the first blade 310 and the second blade 320 of the embodiment of the present application may be both rotatably disposed in the first stepped slot 111, the driving device 400 includes a driving component 410 and an engaging piece 420, the engaging piece 420 is movably disposed in the lens barrel 100, the driving component 410 is used for driving the engaging piece 420 to move, the moving path of the engaging piece 420 is located in a direction of a perpendicular bisector of the first connecting line, the first connecting line is a connecting line between a rotation center of the first blade 310 and a rotation center of the second blade 320, the engaging piece 420 is disposed through the first blade 310 and the second blade 320, and the engaging piece 420 drives the first blade 310 and the second blade 320 to rotate when moving.
Specifically, the first blade 310 and the second blade 320 can both rotate relative to the lens barrel 100 in the first stepped groove 111, and in the embodiment in which the lens barrel 100 is provided with the positioning boss 114 for positioning the third blade 330 and the fourth blade 340, the first blade 310 and the second blade 320 can rotate about the positioning boss 114 as a fulcrum, that is, the positioning boss 114 is a rotation center. The engaging member 420 and the lens barrel 100 can move relatively, and the movement can be smoothly realized under the driving action of the driving assembly 410.
Meanwhile, since the connecting piece 420 is inserted into the first blade 310 and the second blade 320, when the connecting piece 420 moves, an interference relationship exists between the connecting piece and the first blade 310 and the second blade 320, and further the connecting piece also drives the first blade 310 and the second blade 320 to move. Based on the technical feature that the moving path of the linking member 420 is located in the direction of the perpendicular bisector of the first connection, when the linking member 420 moves, it can drive the first blade 310 and the second blade 320 to rotate opposite to each other or rotate opposite to each other, so that the iris diaphragm 300 is switched between the first state and the second state.
Specifically, as shown in fig. 5 and 6, in the process of switching the iris diaphragm 300 from the first state to the second state, the linking member 420 moves from bottom to top in the figure, the first blade 310 and the second blade 320 rotate first in opposite directions and then rotate back to back until they rotate to form the large diaphragm transparent area H2, and in the process of switching the iris diaphragm 300 from the second state to the first state, the linking member 420 moves from top to bottom in the figure, the first blade 310 and the second blade 320 rotate first in opposite directions and then rotate back to back until they rotate to form the small diaphragm transparent area H1.
