Abstract
Description
Technical Field
[0001] This application belongs to the field of image acquisition equipment technology, specifically relating to a lens module and an electronic device. Background Technology
[0002] Currently, commonly used lenses for electronic devices include main cameras, wide-angle lenses, and telephoto lenses. Wide-angle lenses have a long depth of field and a large area of sharpness, mainly used for shooting large-area scenes. Telephoto lenses have a long focal length and a narrow angle of view, suitable for shooting details of distant objects and subjects that are difficult to approach. Main cameras have the most usage scenarios, but they cannot make two objects that are far apart simultaneously sharp.
[0003] Wide-angle and telephoto lenses in existing electronic devices are only used under specific conditions and are often idle. When used alone, neither wide-angle nor telephoto lenses can achieve a state where both distant and close-up views are clear at the same time. If the main camera is used to take pictures, it is impossible to achieve the same level of clarity for both distant and close-up views. If it is necessary to achieve both, some optical parameters, such as aperture and overall height, must be sacrificed. Summary of the Invention
[0004] This application aims to provide a lens module and electronic device that at least solves one of the problems of low lens utilization in electronic devices.
[0005] To solve the above-mentioned technical problems, this application is implemented as follows:
[0006] In a first aspect, embodiments of this application propose a lens module, comprising: a first lens group; a second lens group, the second lens group being arranged spaced apart from the first lens group; and a reflector group, the reflector group having a light-inlet surface and a light-outlet surface, the reflector group being switchable between a first state and a second state; when the reflector group is in the first state, the reflector group is disposed between the first lens group and the second lens group, the light-inlet end of the first lens group receives external light and independently forms an image; when the reflector group is in the second state, the light-inlet surface receives external light or light passing through the first lens group, and the light-outlet surface transmits the light received by the light-inlet surface to the second lens group for imaging.
[0007] Secondly, embodiments of this application provide an electronic device including a lens module as described in the first aspect.
[0008] According to the lens module of this application, by setting a reflector group to cooperate with the first lens group and the second lens group, the reflector group can be switched between different states, so that the first lens group and the second lens group can not only be used independently, but also combined to form a combined image, which improves the utilization rate of the lens, and also reduces the situation of limited image clarity or field of view of a single lens, so as to be suitable for shooting in different scenarios.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0027] The lens module according to an embodiment of this application will now be described in detail with reference to the accompanying drawings.
[0028] like Figures 1 to 6 As shown, the lens module 100 according to an embodiment of this application includes: a first lens group 10, a second lens group 20, and a reflector group 30.
[0029] Specifically, the second lens group 20 is arranged spaced apart from the first lens group 10, and the reflector group 30 has a light-inlet surface and a light-outlet surface. The reflector group 30 can be switched between a first state and a second state. In the first state, the reflector group 30 is positioned between the first lens group 10 and the second lens group 20, and the light-inlet end of the first lens group 10 receives external light and forms an image independently. In the second state, the light-inlet surface receives external light or light passing through the first lens group 10, and the light-outlet surface transmits the light received by the light-inlet surface to the second lens group 20 for imaging.
[0030] In other words, such as Figure 1 and Figure 2 As shown, the lens module 100 according to an embodiment of this application mainly consists of a first lens group 10, a second lens group 20, and a reflector group 30. The first lens group 10 and the second lens group 20 are arranged spaced apart. This spaced-apart arrangement can mean there is a spatial gap between the first lens group 10 and the second lens group 20. The orientation of the light-inlet or light-outlet ends of the first lens group 10 and the second lens group 20 can be the same or different; no specific limitation is made here. Both the first lens group 10 and the second lens group 20 can form images independently. The reflector group 30 can be disposed between the first lens group 10 and the second lens group 20, or it can be disposed on the light transmission path of the first lens group 10 and the second lens group 20.
[0031] The reflector assembly 30 has a light-inlet surface and a light-outlet surface. The reflector assembly 30 can be switched between a first state and a second state. The switching method can be manual adjustment or adjustment by receiving a control signal output by the control unit. The control unit can be a control chip of the associated device or an external controller of the lens module 100. No specific limitation is made here.
[0032] When the reflector group 30 is positioned between the first lens group 10 and the second lens group 20, the reflector group 30 is in the first state. At this time, the first lens group 10 can directly receive external light and form an image independently.
[0033] When the reflector group 30 is in the second state, the light-incoming surface of the reflector group 30 can be located on the light transmission path of the first lens group 10. The light-outcoming surface of the reflector group 30 receives the light entering the reflector group 30 from the light-incoming surface and reflects the light to the second lens group 20, forming an image on the second lens group 20. Alternatively, the light-incoming surface of the reflector group 30 can be located on the transmission path of external natural light. The light-incoming surface of the reflector group 30 receives external light and reflects the light to the second lens group 20, forming an image independently on the second lens group 20.
[0034] It should be noted that the first lens group 10 and the second lens group 20 can be the same lens or different lenses. They can be lenses commonly used in this field, or lenses that can be combined to create different shooting effects. For example, the first lens group 10 can be a wide-angle lens group, and the second lens group 20 can be a telephoto lens group. When the first lens group 10 and the second lens group 20 are used together, a camera module design scheme with a large depth of field effect can be achieved according to the Fraser lens principle.
[0035] Therefore, according to the lens module 100 of this application, by setting the reflector group 30 to cooperate with the first lens group 10 and the second lens group 20, the reflector group 30 can be switched between different states, so that the first lens group 10 and the second lens group 20 can not only be used individually, but also combined to form a combined image, which improves the utilization rate of the lens, and also reduces the situation of limited image clarity or field of view of a single lens, so as to be suitable for shooting in different scenarios.
[0036] According to one embodiment of this application, the second state includes a first working state and a second working state.
[0037] Specifically, when the reflector group 30 is in the first working state, the light-inlet surface receives external light, and the light-outlet surface transmits the light received by the light-inlet surface to the second lens group 20 for imaging; when the reflector group 30 is in the second working state, the light-inlet surface receives light passing through the first lens group 10, and the light-outlet surface transmits the light received by the light-inlet surface to the second lens group 20 for imaging.
[0038] In other words, the second state of the mirror assembly 30 can include both a first operating state and a second operating state, such as... Figure 3 and Figure 4 As shown, when the reflector group 30 is in the first working state, the light-incoming surface of the reflector group 30 does not form a light-matching relationship with the first lens group 10, but receives the light incident from the outside. The light-outcoming surface of the reflector group 30 transmits the light received by its light-incoming surface to the second lens group 20 for imaging. The reflector group 30 reflects the external light and transmits it to the second lens group 20, so as to realize the second lens group 202 imaging independently without changing the light transmission trajectory of the first lens group 10.
[0039] like Figure 5 and Figure 6As shown, when the reflector group 30 is in the second working state, the light-inlet surface of the reflector group 30 is located on the light transmission path of the first lens group 10. The light-inlet surface can receive the light passing through the first lens group 10, and the light-outlet surface of the reflector group 30 transmits the light received by its light-inlet surface to the second lens group 20 for imaging. This enables the primary image output by the first lens group 10 to be transmitted to the second lens group 20 through the reflector group 30. The second lens group 20 then reprocesses the primary image and outputs a secondary image.
[0040] Therefore, according to the lens module 100 of this application embodiment, by setting a reflector group 30 with two working states, it can realize the independent imaging of the second lens group 20, and can also realize the cooperative imaging of the second lens group 20 and the first lens group 10, thereby realizing different lens combinations to improve the clarity or field of view of the captured image and further improve the utilization rate of the lens.
[0041] According to one embodiment of this application, the reflector group 30 includes a first reflector 31 and a second reflector 32.
[0042] Specifically, the first reflector 31 has a light-inlet surface and is movable in a first direction; the second reflector 32 has a light-outlet surface and is disposed opposite to the first reflector 31, and is movable in the first direction; when the reflector group 30 is in the first state, the first reflector 31 and the second reflector 32 are respectively located between the first lens group 10 and the second lens group 20; when the reflector group 30 is in the second state, the first reflector 31 is located in the light transmission path of the first lens group 10 or between the first lens group 10 and the second lens group 20, and the second reflector 32 is located in the light transmission path of the second lens group 20.
[0043] In other words, a horizontal moving guide rail 7 can be installed inside an electronic device, such as... Figure 1 , Figure 3 as well as Figure 5 As shown, both the first reflector 31 and the second reflector 32 can slide horizontally between the horizontal moving guide rails 7, and both the first reflector 31 and the second reflector 32 can slide along the length direction (i.e., the first direction) of the horizontal moving guide rails 7.
[0044] like Figure 1 and Figure 2As shown, when the reflector group 30 is in the first state, the first reflector 31 can slide on the horizontal moving guide rail 7 to its extreme position away from the first lens group 10, and the second reflector 32 can slide on the horizontal moving guide rail 7 to its extreme position away from the second lens group 20. At this time, the first lens group 10 and the second lens group 20 are in their closest positions. Correspondingly, both the first lens group 10 and the second lens group 20 can be in an idle state or in a state of independent operation.
[0045] like Figure 3 and Figure 4 As shown, when the mirror assembly 30 is in the first working state, the second mirror 32 can slide on the horizontal moving guide rail 7 to a position close to the second lens assembly 20. At this time, the light-emitting surface of the second mirror 32 faces the light-incoming end of the second lens assembly 20. The first mirror 31 can transmit external light to the second mirror 32, and then the second mirror 32 outputs it to the second lens assembly 20 to achieve independent imaging of the second lens assembly 20.
[0046] like Figure 5 and Figure 6 As shown, when the mirror assembly 30 is in its second operating state, the first mirror 31 moves closer to the first lens assembly 10, and the second mirror 32 moves closer to the second lens assembly 20. At this time, the light-incoming surface of the first mirror 31 faces the light-outgoing surface of the first lens assembly 10, and the light-outgoing surface of the second mirror 32 faces the light-incoming surface of the second lens assembly 20. The first lens assembly 10 can transmit external light to the first mirror 31, and the light passing through the first mirror 31 is transmitted to the second mirror 32 and imaged on the second lens assembly 20.
[0047] Therefore, according to the embodiment of this application, the lens module 100 changes the spatial position of the two reflectors. On the one hand, it enables the first lens group 10 and the second lens group 20 to image individually or in combination. On the other hand, when the reflector group 30 is not working, the reflector group 30 moves into the internal space of the electronic device and is located between the first lens group 10 and the second lens group 20, thereby improving the utilization rate of the internal space of the electronic device.
[0048] According to one embodiment of this application, the first reflector 31 and the second reflector 32 are prisms, respectively.
[0049] Specifically, the first reflector 31 has a light-inlet surface and a light-outlet surface, and the second reflector 32 has a light-inlet surface and a light-outlet surface, with the light-outlet surface and the light-inlet surface arranged opposite to each other.
[0050] In other words, a prism can reflect vertically input light rays horizontally, so that with the cooperation of two prisms, the light rays can be reversed, such as... Figure 3 and Figure 4 Therefore, when the mirror assembly 30 is in the first working state, the external light entering from the light-inlet surface of the first mirror 31 can be output from the light-outlet surface of the second mirror 32 so that the second lens assembly 20 can form an image.
[0051] like Figure 5 and Figure 6 When the reflector group 30 is in the second working state, the first reflector 31 moves to the light transmission path of the first reflector 31. The first reflector 31 can receive the light passing through the first lens group 10 and output it to the second lens 21 by the second reflector 32, thereby realizing the combined imaging of the first lens 11 and the second lens 21.
[0052] Therefore, according to the lens module 100 of this application embodiment, by utilizing the optical characteristics of the prism, the first reflecting mirror 31 or the second reflecting mirror 32 can be moved to any position on the horizontal moving guide rail 7, and the light emitted through the first reflecting mirror 31 can be output to the optical incident surface of the second reflecting mirror 32, thereby reducing the change in the light path of the first reflecting mirror 31 after the first reflecting mirror 31 or the second reflecting mirror 32 moves, and improving the integrity of the imaging of the second lens 21.
[0053] According to one embodiment of this application, a first lens group 10 is movable between a first initial position and a first working position along a second direction, and a second lens group 20 is movable between a second initial position and a second working position along a second direction, wherein the second direction is perpendicular to the first direction.
[0054] Specifically, when the reflector group 30 is in the first state, the first lens group 10 is in the first initial position and the second lens group 20 is in the second initial position; when the reflector group 30 is in the first working state, the first lens group 10 is in the first initial position and the second lens group 20 is in the second working position, the first reflector 31 is located between the first lens group 10 and the second lens group 20, and the second reflector 32 is located at the light-inlet end of the second lens group 20 in the second direction; when the reflector group 30 is in the second working state, the first lens group 10 is in the first working position and the second lens group 20 is in the second working position, the first reflector 31 is located at the light-outlet end of the first lens group 10 in the second direction, and the second reflector 32 is located at the light-inlet end of the second lens group 20 in the second direction.
[0055] In other words, a vertical moving guide rail 8 is provided on the electronic device along its thickness direction, such as... Figure 1 and Figure 5As shown, the first lens group 10 and the second lens group 20 each correspond to a vertical moving guide rail 8. Both the first lens group 10 and the second lens group 20 can slide along the length direction (i.e., the second direction) of the vertical moving guide rail 8. The horizontal moving guide rail 7 can also be set inside the electronic device. Correspondingly, the vertical moving guide rail 8 is perpendicular to the horizontal moving guide rail 7. Either the first lens 11 or the second lens 21 can extend out of the electronic device along the vertical moving guide rail 8. The extreme position of the first lens 11 is the first working position, and the extreme position of the second lens 21 is the second working position. Alternatively, it can retract into the electronic device along the vertical moving guide rail 8. The extreme position of the second lens 21 retracting is the first initial position, and the extreme position of the second lens 21 extending is the second initial position.
[0056] like Figure 1 and Figure 2 As shown, when the reflector group 30 is in the first state, the first lens group 10 is in the first initial position and the second lens group 20 is in the second initial position. At this time, the first lens group 10 and the second lens group 20 may not work or may start working independently.
[0057] like Figure 3 and Figure 4 As shown, when the reflector group 30 is in the first working state, the first lens group 10 is located in the first initial position, the second lens group 20 is located in the second working position, the first reflector 31 is located between the first lens group 10 and the second lens group 20, and the second reflector 32 is located at the light-inlet end of the second lens group 20 in the second direction. At this time, the first lens group 10 and the second lens group 20 can work independently or both can work independently.
[0058] like Figure 5 and Figure 6 As shown, when the mirror group 30 is in the second working state, the first lens group 10 is located in the first working position, the second lens group 20 is located in the second working position, the first mirror 31 is located at the light-emitting end of the first lens group 10 in the second direction, and the second mirror 32 is located at the light-incoming end of the second lens group 20 in the second direction. At this time, the first lens group 10 and the second lens group 20 can be combined through the mirror group 30 to achieve joint imaging.
[0059] Therefore, according to the lens module 100 of this application embodiment, the first lens group 10 and the second lens group 20 move along the thickness of the electronic device. When the electronic device is in a non-photographing mode, the first lens 11 and the second lens 21 are located inside the electronic device, which can effectively reduce wear on the light-gathering ends of the first lens group 10 and the second lens group 20. When the electronic device is in a photographing mode, the light-gathering ends of the first lens group 10 and / or the second lens group 20 extend out of the electronic device, reducing the dim lighting conditions when the first lens group 10 and / or the second lens group 20 are inside the electronic device, and improving the imaging quality of the electronic device.
[0060] In some specific embodiments of this application, the first lens group 10 includes a first lens 11 and a first photosensitive chip 12. The first lens 11 is movable, and the first photosensitive chip 12 is disposed at the light-emitting end of the first lens 11. When the reflector group 30 is in the second working state, the first reflector 31 is located between the first lens 11 and the first photosensitive chip 12.
[0061] In other words, the first lens 11 can slide on the corresponding vertical moving guide rail 8, and the first photosensitive chip 12 can be installed in a corresponding electronic device. The first lens 11 can then transmit external light to the first photosensitive chip 12, so that the first photosensitive chip 12 can image the light output by the first lens 11. The first photosensitive chip 12 can be a light-sensitive chip. Figure 1 , Figure 3 as well as Figure 5 As shown, when the mirror assembly 30 is in the first state or the first working state, the first mirror 31 is located on the side of the first lens 11 closer to the second lens assembly 20, and the second lens assembly 20 can form an image through the first mirror 31 and the second mirror 32. When the mirror assembly 30 is in the second working state, the first mirror 31 is located between the first lens 11 and the first photosensitive chip 12, and the first mirror 31 transmits the light passing through the first lens 11 to the second mirror 32, so that no image can be formed on the first photosensitive chip 12.
[0062] Therefore, in the lens module 100 according to the embodiment of this application, the first lens 11 slides on the vertical moving guide rail 8 and a cavity is formed between the first lens 11 and the first photosensitive chip 12 for placing the first reflector 31, so as to realize the switching between imaging from the second lens group 20 alone to imaging from the first lens group 10 and the second lens group 20 combined.
[0063] Optionally, according to one embodiment of this application, the second lens group 20 includes a second lens 21 and a second photosensitive chip 22, the second lens 21 and the second photosensitive chip 22 are synchronously active, and the second photosensitive chip 22 is disposed at the light-emitting end of the second lens 21.
[0064] In other words, such as Figure 3 and Figure 5 As shown, the second lens 21 and the second photosensitive chip 22 can be synchronously connected through methods such as bonding, welding, or plugging, which are not limited here. The second photosensitive chip 22 is disposed at the light-emitting end of the second lens 21 to image the light output from the second lens 21. When the second lens group 20 images alone, external light can be input into the second lens 21 along a fourth direction through the reflector group 30 and imaged on the second photosensitive chip 22. When the first lens group 10 and the second lens group 20 combine to image, light can also be input into the second lens 21 from the same fourth direction through the reflector group 30. The fourth direction can be the direction along the optical axis of the second lens and towards the light-receiving surface of the second lens.
[0065] Therefore, in the lens module 100 according to the embodiment of this application, since the second lenses 21 all receive light from the fourth direction, the second lenses 21 and the second photosensitive chip 22 move synchronously, that is, the distance between the second lenses 21 and the second photosensitive chip 22 is relatively fixed, so that the second photosensitive chip 22 can be in a better imaging position, thereby improving the imaging quality of the second lens group.
[0066] In some optional embodiments of this application, according to one embodiment of this application, the first lens group 10 is a wide-angle lens group and the second lens group 20 is a telephoto lens group. In the second direction, the movement distance of the first lens group 10 is less than the movement distance of the second lens group 20.
[0067] In other words, the first lens 11 of the first lens group 10 can be a wide-angle lens, and the second lens 21 of the second lens group 20 can be a telephoto lens. For example... Figure 1 and Figure 2 As shown, when the reflector group 30 is in the first state, the wide-angle lens and the telephoto lens can work independently or not at all; for example... Figure 3 and Figure 4 As shown, the telephoto lens can operate when the reflector group 30 is in its first working state; as Figure 5 and Figure 6 As shown, when the reflector group 30 is in the second working state, the wide-angle lens and the telephoto lens can work together to form a Fraser lens. The telephoto lens can bring distant objects closer, while the wide-angle lens can capture a wider range of objects.
[0068] Therefore, according to the lens module 100 of this application embodiment, the first lens group 10, as a wide-angle lens group, can be used to shoot distant scenes, and the second lens group 20, as a telephoto lens group, can be used to shoot close-up scenes. The wide-angle lens group and the telephoto lens group are combined through the reflecting mirror group 30 to achieve a large wide-angle lens with a large imaging circle. When the field lens 4 is positioned between the wide-angle lens group and the telephoto lens group, the wide-angle lens group projects an image with a large depth of field onto the field lens 4, and then a telephoto lens group captures the image on the field lens 4 to achieve zoom and control the aperture, thereby achieving clear imaging for both near and far scenes.
[0069] According to one embodiment of this application, the field mirror 4 is disposed between the first reflecting mirror 31 and the second reflecting mirror 32.
[0070] In other words, the field lens 4 can be positioned between the first lens group 10 and the second lens group 20, with the light-incident surface of the field lens 4 facing the light-out surface of the first reflector 31 and the light-transmitting surface of the field lens 4 facing the light-incident surface of the second reflector 32.
[0071] Therefore, according to the lens module 100 of this application embodiment, when the first lens 11 and the second lens group 20 combine to form an image, the field lens 4 can collect light passing through the edge of the first lens 11, reducing vignetting and magnifying the intermediate image to improve the quality of the captured image. When the image is formed on the second lens group 20 through the reflecting mirror group 30, the field lens 4 can collect light passing through the edge of the first reflecting mirror 31 to improve the image quality when the second lens group 20 forms an image independently.
[0072] Optionally, according to one embodiment of this application, the lens module 100 further includes a first cover plate 5 and a second cover plate 6.
[0073] Specifically, the first cover plate 5 is movable in a third direction to block or avoid the light transmission of the first lens group 10; the second cover plate 6 is movable in a third direction to block or avoid the light transmission of the second lens group 20; wherein the second direction is perpendicular to the first direction and the third direction respectively.
[0074] In other words, the corresponding electronic device can also be equipped with a glass moving guide rail 9, which can be set perpendicular to both the horizontal moving guide rail 7 and the vertical moving guide rail 8, so that the first cover plate 5 and the second cover plate 6 can slide on the corresponding glass moving guide rail 9. The first lens group 10 and the second lens group 20 each correspond to a glass moving guide rail 9. The length of the glass moving guide rail 9 corresponding to the second lens group 20 is greater than that corresponding to the first lens group 10, so that the glass moving guide rail 9 corresponding to the second lens group 20 can cover the light-gathering surface of the first reflector 31. Therefore, when both the second lens 21 and the first reflector 31 are blocked by the glass moving guide rail 9, the first lens group 10 can work independently, or the first lens group 10 and the second lens group 20 can be combined to form an image. Similarly, when the first lens group 10 is blocked by the glass moving guide rail 9, the second lens group 20 can work independently. When the first cover plate 5 and the second cover plate 6 simultaneously avoid each other, the first lens group 10 and the second lens group 20 can work independently, or they can be combined using the reflector group 30.
[0075] Therefore, according to the lens module 100 of this application embodiment, the first cover plate 5 can reduce the wear of the mirror surface of the first lens group 10 when the first lens group 10 is idle, and the second cover plate 6 can reduce the wear of the mirror surface of the second lens group 20 and the mirror surface of the mirror group 30 when the second lens group 20 is idle.
[0076] The electronic device according to the embodiments of this application includes the lens module 100 in any of the above embodiments.
[0077] Since the lens module 100 according to the above embodiments of this application has the aforementioned technical effects, the electronic device according to the embodiments of this application also has corresponding technical effects. That is, the electronic device can combine its own lenses to improve lens utilization and improve the clarity or field of view of the captured image. The images captured by the electronic device have better clarity and field of view, thus improving the user experience.
