Description

Technical Field

[0001] This application relates to the field of optical technology, and in particular to a lens assembly, camera module and terminal device. Background Technology

[0002] Optical zoom is a technology that enables changes in focal length. Optical zoom does not involve digital processing or image magnification and can maintain high image quality and clarity.

[0003] However, lens assemblies with optical zoom function usually change the focusing position of light by adjusting the relative positions of the lenses in the lens assembly, thereby adjusting the focal length. Their structural form is simple and cannot meet the increasingly diverse needs of different scenarios. Summary of the Invention

[0004] This application provides a lens assembly, a camera module, and a terminal device, which can solve the problem that the lens assembly with optical zoom function has a single structural form and cannot meet the increasingly diverse needs of various scenarios.

[0005] The technical solution is as follows:

[0006] On one hand, a lens assembly is provided, the lens assembly including: a second lens group, a third lens group, a first lens group, and an optical path deflection element;

[0007] The first lens group is located on the first optical axis, and the optical path deflection element is located in the light-emitting direction of the first lens group;

[0008] The second lens group is located on the second optical axis, and the third lens group is located on the third optical axis. The second optical axis and the third optical axis intersect the first optical axis perpendicularly, respectively.

[0009] The optical path deflection element includes a first position and a second position that can be switched.

[0010] At the first position, the optical path turning element is located at the intersection of the first optical axis and the second optical axis, and the optical path turning element is used to turn the optical path from the first optical axis to the second optical axis;

[0011] In the second position, the optical path reversing element is located at the intersection of the first optical axis and the third optical axis, and the optical path reversing element is used to revers the optical path from the first optical axis to the third optical axis.

[0012] The lens assembly provided in this embodiment has an optical path reversing element arranged after the first lens group. The optical path reversing element can be switched between a first position and a second position to make the first optical axis and the second optical axis intersect, and the first optical axis and the third optical axis intersect, respectively. The second lens group and the third lens group are arranged on the second optical axis and the third optical axis, respectively. The two lenses can have different optical characteristics, so that the lens assembly can achieve different optical effects. Only the optical path reversing element is a moving part in the lens assembly. As long as the accuracy of the optical path reversing element is guaranteed, less tolerance can be introduced, and the lens assembly has less stray light.

[0013] In addition, the second and third lens groups in the lens assembly are arranged along a second optical axis and a third optical axis that are different from the first optical axis. The size of the lens assembly along the first optical axis is small, and the second and third optical axes only need to be perpendicular to the first optical axis, which has a large flexible arrangement space. This is conducive to improving the flexibility of the lens assembly, enabling the lens assembly to have a variety of different product shapes, which can adapt to the stacking space in different usage scenarios and improve the application range of the lens assembly.

[0014] In some possible implementations, the first lens group includes a first lens, the object-side surface and the image-side surface of the first lens being spherical, and the first lens being made of glass material.

[0015] In this embodiment, the first lens group is composed of a first lens, which occupies a small size only on the first optical axis, and the lens assembly has a small size along the first optical axis.

[0016] The object-side and image-side surfaces of the first lens are both spherical, offering advantages such as low manufacturing cost and ease of mass production. Secondly, by optimizing the curvature combination of the two spherical surfaces (e.g., positive-negative lens pairing), spherical aberration on the first optical axis can be effectively compensated; for example, the double Gaussian structure corrects spherical aberration and field curvature. The double-spherical first lens facilitates a symmetrical layout along the first optical axis, reducing assembly sensitivity (strong tolerance adaptability) and avoiding assembly problems such as eccentricity and tilt. Thirdly, the first lens is less affected by temperature changes, resulting in more stable refractive index matching and reduced performance fluctuations at high / low temperatures. Furthermore, the dispersion characteristics of the first lens are easier to correct for chromatic aberration through material matching, making it suitable for multi-band imaging (visible to near-infrared).

[0017] In some possible implementations, the object-side surface of the first lens is convex, and the image-side surface of the first lens is concave.

[0018] With the above arrangement, the first lens has a high spherical aberration compensation and field curvature suppression effect. The first lens is formed into a convex-concave positive meniscus shape, which can serve as the core element of the double Gaussian symmetry structure. The optical axis symmetry is achieved by superimposing the "convex-concave" shape, which significantly expands the aperture. The divergence effect of the concave surface can widen the light cone angle and reduce edge vignetting under large aperture.

[0019] In some possible implementations, the relative positions of the second optical axis and the third optical axis are any one of coincidence, parallelism, intersection, or non-plane orientation.

[0020] With the above arrangement, the second and third lens groups in the lens assembly have a large amount of flexible arrangement space, which can improve the flexibility of the lens assembly, enabling the lens assembly to have a variety of different product shapes, adapt to the stacking space in different usage scenarios, and improve the application range of the lens assembly.

[0021] In some possible implementations, the second lens group and the third lens group have different optical parameters. Thus, the lens assembly can switch between the two optical parameters using an optical path deflection element, enabling the lens assembly to have two imaging effects and improving the overall imaging performance.

[0022] In some possible implementations, the second lens group includes a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens arranged sequentially along the light-incident direction;

[0023] The object-side surface of the second lens is convex, and the image-side surface of the second lens is convex; the object-side surface of the third lens is convex, and the image-side surface of the third lens is either convex or concave; the object-side surface of the fourth lens is convex, and the image-side surface of the fourth lens is either convex or concave; the object-side surface of the fifth lens is concave, and the image-side surface of the fifth lens is either convex or concave; the object-side surface of the sixth lens is either convex or concave, and the image-side surface of the sixth lens is either convex or concave.

[0024] In this embodiment, the second lens group has a simple structure and good optical performance.

[0025] In some possible implementations, the third lens group includes a seventh lens, an eighth lens, a ninth lens, a tenth lens, and an eleventh lens arranged sequentially along the light-gathering direction.

[0026] The object-side surface of the seventh lens is convex, and the image-side surface of the seventh lens is convex; the object-side surface of the eighth lens is convex, and the image-side surface of the eighth lens is either convex or concave; the object-side surface of the ninth lens is convex, and the image-side surface of the ninth lens is either convex or concave; the object-side surface of the tenth lens is concave, and the image-side surface of the tenth lens is either convex or concave; the object-side surface of the eleventh lens is either convex or concave, and the image-side surface of the eleventh lens is either convex or concave.

[0027] In this embodiment, the third lens group has a simple structure and good optical performance.

[0028] In some possible implementations, the lens assembly further includes a first aperture stop and a second aperture stop, the first aperture stop being located on the second optical axis and the second optical axis being located on the third optical axis.

[0029] With the above arrangement, the first and second apertures adjust their aperture sizes to control the amount of light entering the lens, thereby affecting the brightness of the image and achieving correct exposure of the lens assembly.

[0030] On the other hand, a camera module is provided, the camera module including: the lens assembly described in this application, and a first imaging assembly and a second imaging assembly;

[0031] The first imaging component is located on the light-emitting side of the second lens group, and the second imaging component is located on the light-emitting side of the third lens group.

[0033] On the other hand, a terminal device is provided, which includes the lens assembly described in this application or the camera module described in the claims.

[0064] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0065] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0066] On the one hand, combined with Figure 1 and Figure 2As shown, this embodiment provides a lens assembly, which includes: a first lens group 3, a second lens group 1, a third lens group 2, and an optical path deflection element 4.

[0067] The first lens group 3 is located on the first optical axis 001, the optical path deflection element 4 is located in the light output direction of the first lens group 3, the second lens group 1 is located on the second optical axis 002, and the third lens group 2 is located on the third optical axis 003. The second optical axis 002 and the third optical axis 003 intersect the first optical axis 001 perpendicularly, respectively.

[0068] The optical path switching element 4 includes a first position and a second position that can be switched.

[0069] In the first position, the optical path turning element 4 is located at the intersection of the first optical axis 001 and the second optical axis 002. The optical path turning element 4 is used to turn the optical path from the first optical axis 001 to the second optical axis 002.

[0070] In the second position, the optical path turning element 4 is located at the intersection of the first optical axis 001 and the third optical axis 003. The optical path turning element 4 is used to turn the optical path from the first optical axis 001 to the third optical axis 003.

[0071] The lens assembly provided in this embodiment has an optical path reversing element 4 arranged after the first lens group 3. The optical path reversing element 4 can be switched between a first position and a second position to make the first optical axis 001 and the second optical axis intersect, and the first optical axis 001 and the third optical axis 003 intersect, respectively. The second lens group 1 and the third lens group 2 are arranged on the second optical axis 002 and the third optical axis 003, respectively. The two lens groups can have different optical characteristics, so that the lens assembly can achieve different optical effects. Only the optical path reversing element 4 is a moving part in the lens assembly. As long as the accuracy of the optical path reversing element 4 is guaranteed, less tolerance can be introduced, and the lens assembly has less stray light.

[0072] Furthermore, the second lens group 1 and the third lens group 2 in the lens assembly are arranged along the second optical axis 002 and the third optical axis 003, which are different from the first optical axis 001, respectively. The size of the lens assembly along the first optical axis 001 is relatively small, and the second optical axis 002 and the third optical axis 003 only need to be perpendicular to the first optical axis 001, which provides a large amount of flexible arrangement space. This is beneficial to improving the flexibility of the lens assembly, enabling the lens assembly to have a variety of different product shapes, which can adapt to the stacking space under different usage scenarios and improve the application range of the lens assembly.

[0073] In this embodiment, the optical path deflection element 4 can deflect light along the first optical axis 001, the second optical axis 002 and the third optical axis 003, so that the lens assembly is formed as a periscope optical lens, which can make full use of the thickness, length or width space inside the terminal device and improve the space utilization of the terminal device.

[0074] In some possible implementations, the optical path deflection element 4 includes a reflector and a driving unit. The driving unit can drive the reflector to rotate, translate, or perform other movements, so that when the reflector is in the first position, the light rays of the first optical axis 001 can be deflected to the second optical axis 002, and when the reflector is in the second position, the light rays of the first optical axis 001 can be deflected to the third optical axis 003.

[0075] Combination Figure 1 and Figure 2 As shown, in some possible embodiments, the first lens group 3 includes a first lens, the object side and the image side of the first lens are spherical, and the first lens is made of glass material.

[0076] In this embodiment, the first lens group 3 is composed of the first lens and occupies a small size only on the first optical axis 001. The size of the lens assembly along the first optical axis 001 is small.

[0077] The object-side and image-side surfaces of the first lens are both spherical, offering advantages such as low manufacturing cost and ease of mass production. Secondly, by optimizing the curvature combination of the two spherical surfaces (e.g., positive-negative lens pairing), spherical aberration on the first optical axis (001) can be effectively compensated; for example, the double Gaussian structure corrects spherical aberration and field curvature. The double-spherical first lens facilitates a symmetrical layout along the first optical axis (001), reducing assembly sensitivity (strong tolerance adaptability) and avoiding assembly problems such as eccentricity and tilt. Thirdly, the first lens is less affected by temperature changes, resulting in more stable refractive index matching and reduced performance fluctuations at high / low temperatures. Furthermore, the dispersive characteristics of the first lens are easier to correct for chromatic aberration through material matching, making it suitable for multi-band imaging (visible to near-infrared).

[0078] Combination Figure 1 As shown, in some possible implementations, the object-side surface of the first lens is convex, and the image-side surface of the first lens is concave.

[0079] With the above arrangement, the first lens has a high spherical aberration compensation and field curvature suppression effect. The first lens is formed into a convex-concave positive meniscus shape, which can serve as the core element of the double Gaussian symmetry structure. The optical axis symmetry is achieved by superimposing the "convex-concave" shape, which significantly expands the aperture. The divergence effect of the concave surface can widen the light cone angle and reduce edge vignetting under large aperture.

[0080] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some possible implementations, the relative positions of the second optical axis 002 and the third optical axis 003 are any one of coincidence, parallelism, intersection, or non-plane.

[0081] With the above arrangement, the second lens group 1 and the third lens group 2 in the lens assembly have a large amount of flexible arrangement space, which can improve the flexibility of the lens assembly, enabling the lens assembly to have a variety of different product shapes, adapt to the stacking space under different usage scenarios, and improve the application range of the lens assembly.

[0082] In some possible implementations, refer to Figure 1 and Figure 2 As shown, the relative positions of the second optical axis 002 and the third optical axis 003 coincide, and the intersection of the first optical axis 001 and the second optical axis 002 coincides with the intersection of the first optical axis 001 and the third optical axis 003. The optical path deflection element 4 includes a reflector and a rotating shaft structure. The reflector is capable of reflecting light rays from the first optical axis 001 toward the second optical axis 002 or the third optical axis 003. The rotating shaft structure is connected to the reflector and can drive the reflector to rotate around the aforementioned intersection point.

[0083] In some possible implementations, the second lens group 1 and the third lens group 2 have different optical parameters. Thus, the lens assembly can switch between the two optical parameters using the optical path deflection element 4, enabling the lens assembly to have two imaging effects and improving the overall imaging performance.

[0084] In some possible implementations, the different optical parameters of the second lens group 1 and the third lens group 2 can be focal length, radius of curvature, thickness and spacing, refractive index, Abbe number, optical power, etc.

[0085] For example, the second lens group 1 and the third lens group 2 have different focal lengths. For instance, the second lens group 1 has a short focal length and the third lens group 2 has a long focal length, or the second lens group 1 has a long focal length and the third lens group 2 has a short focal length.

[0086] Combination Figure 7 As shown, in some possible embodiments, the second lens group 1 includes a second lens 11, a third lens 12, a fourth lens 13, a fifth lens 14, and a sixth lens 15 arranged sequentially along the light-incident direction.

[0087] The object-side surface of the second lens 11 is convex, and the image-side surface of the second lens 11 is convex; the object-side surface of the third lens 12 is convex, and the image-side surface of the third lens 12 is either convex or concave; the object-side surface of the fourth lens 13 is convex, and the image-side surface of the fourth lens 13 is either convex or concave; the object-side surface of the fifth lens 14 is concave, and the image-side surface of the fifth lens 14 is either convex or concave; the object-side surface of the sixth lens 15 is either convex or concave, and the image-side surface of the sixth lens 15 is either convex or concave.

[0088] In this embodiment, the second lens group 1 has a simple structure and good optical performance.

[0089] Combination Figure 8 As shown, in some possible embodiments, the third lens group 2 includes a seventh lens 21, an eighth lens 22, a ninth lens 23, a tenth lens 24, and an eleventh lens 25 arranged sequentially along the light-gathering direction.

[0090] The object-side surface of the seventh lens 21 is convex, and the image-side surface of the seventh lens 21 is convex; the object-side surface of the eighth lens 22 is convex, and the image-side surface of the eighth lens 22 is either convex or concave; the object-side surface of the ninth lens 23 is convex, and the image-side surface of the ninth lens 23 is either convex or concave; the object-side surface of the tenth lens 24 is concave, and the image-side surface of the tenth lens 24 is either convex or concave; the object-side surface of the eleventh lens 25 is either convex or concave, and the image-side surface of the eleventh lens 25 is either convex or concave.

[0091] In this embodiment, the third lens group 2 has a simple structure and good optical performance.

[0092] Combination Figure 7 and Figure 8 As shown, in some possible embodiments, the lens assembly further includes a first aperture stop 5 and a second aperture stop 6, the first aperture stop 5 being located on the second optical axis 002 and the second optical axis 002 being located on the third optical axis 003.

[0093] With the above arrangement, the first aperture 5 and the second aperture 6 adjust the aperture size to control the amount of light entering, thereby affecting the brightness of the image and achieving correct exposure of the lens assembly.

[0106] On the other hand, combining Figure 1 and Figure 2 As shown, this embodiment provides a camera module, which includes: the lens assembly of this application, and a first imaging assembly 7 and a second imaging assembly 8; the first imaging assembly 7 is located on the light-emitting side of the second lens group 1, and the second imaging assembly 8 is located on the light-emitting side of the third lens group 2.

The sensor consists of thousands of photosensitive units (pixels), each capable of sensing the intensity and color of light. Optionally, the sensor can be of any of the following types:

[0110] Complementary Metal Oxide Semiconductor (CMOS) Sensors: CMOS sensors are currently the most common type of camera sensor, offering advantages such as low power consumption, high integration, and cost-effectiveness. CMOS sensors enable fast readout and high-resolution images, making them suitable for most digital cameras and mobile phone cameras.

[0111] Charge Coupled Device (CCD) Sensor: CCD sensors were widely used in digital cameras in the past because they have high image quality and low noise levels.

[0117] The variable aperture or camera module is electrically connected to the processor. The processor is the control center of the terminal device, connecting various parts of the phone via various interfaces and lines. It performs various functions and processes data by running or executing software programs and / or modules stored in the memory, and by calling data stored in the memory, thereby providing overall monitoring of the phone. Optionally, the processor may include one or more processing cores; preferably, the processor may integrate an application processor and a modem processor, wherein the application processor mainly handles the operation of the storage medium, user interface, and applications, while the modem processor mainly handles wireless communication.
