The following describes a lens module according to an embodiment of the present application with reference to the drawings.

As shown in fig. 1 to 6, a lens module 100 according to an embodiment of the present disclosure includes: a first lens group 10, a second lens group 20 and a reflecting mirror group 30.

Specifically, the second lens group 20 is disposed spaced apart from the first lens group 10, the mirror group 30 has a light-entering surface and a light-exiting surface, and the mirror group 30 is switchable between a first state and a second state. Wherein, under the condition that the reflector 30 is in the first state, the reflector 30 is disposed between the first lens group 10 and the second lens group 20, and the light-in end of the first lens group 10 receives external light and forms images independently; when the reflecting lens assembly 30 is in the second state, the light-entering surface receives external light or light passing through the first lens assembly 10, and the light-exiting surface transmits the light received by the light-entering surface to the second lens assembly 20 for imaging.

In other words, as shown in fig. 1 and fig. 2, the lens module 100 according to the embodiment of the present application mainly comprises a first lens group 10, a second lens group 20 and a reflector group 30, wherein the first lens group 10 and the second lens group 20 are arranged at a distance, which may be a space between the first lens group 10 and the second lens group 20, and the light-in end or the light-out end of the first lens group 10 and the second lens group 20 may have the same or different directions, which is not limited herein. The first lens group 10 and the second lens group 20 can be imaged independently, and the reflecting lens group 30 can be disposed between the first lens group 10 and the second lens group 20, or disposed on the light transmission path of the first lens group 10 and the second lens group 20.

The reflecting mirror group 30 has a light inlet surface and a light outlet surface, and the reflecting mirror group 30 can be switched between the first state and the second state, and the switching manner can be manually adjusted by a person or adjusted by receiving a control signal output by a control unit, where the control unit can be a control chip of an associated device or a controller externally connected to the lens module 100, and is not limited specifically here.

When the reflector 30 is disposed between the first lens group 10 and the second lens group 20, the reflector 30 is in the first state, and the first lens group 10 can directly receive external light and form images independently.

When the mirror group 30 is in the second state, the light incident surface of the mirror group 30 can be located on the light transmission path of the first lens group 10, and the light emergent surface of the mirror group 30 receives the light incident into the mirror group 30 from the light incident surface, reflects the light to the second lens group 20, and forms an image on the second lens group 20. The light entrance surface of the reflector assembly 30 can also be located on the transmission path of the external natural light, and the light entrance surface of the reflector assembly 30 receives the external light and reflects the light to the second lens assembly 20 to form an image on the second lens assembly 20 independently.

It should be noted that the first lens group 10 and the second lens group 20 may be the same lens, or different lenses, or may be lenses commonly used in the art, or may be lenses capable of forming different shooting effects by matching, for example, the first lens group 10 may be a wide-angle lens group, the second lens group 20 may be a telephoto lens group, the first lens group 10 and the second lens group 20 are used together, and according to the frazier lens principle, a design scheme of a camera module capable of achieving a large depth of field effect may be achieved.

Therefore, according to the lens module 100 of the present 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 is switchable between different states, so that the first lens group 10 and the second lens group 20 can not only be used alone, but also the first lens group 10 and the second lens group 20 can be combined, so that the first lens group 10 and the second lens group 20 are combined to image, the utilization rate of the lenses is improved, and meanwhile, the condition of single lens image definition or limited visual field is also reduced, so as to be suitable for shooting in different scenes.

According to an embodiment of the application, the second state comprises a first operating state and a second operating state.

Specifically, when the reflecting mirror group 30 is in the first working state, the light entering surface receives external light, and the light exiting surface transmits the light received by the light entering surface to the second lens group 20 for imaging; when the reflector assembly 30 is in the second working state, the light entering surface receives the light passing through the first lens assembly 10, and the light exiting surface transmits the light received by the light entering surface to the second lens assembly 20 for imaging.

In other words, the second state of the mirror group 30 can include a first working state and a second working state, as shown in fig. 3 and 4, when the mirror group 30 is in the first working state, the light entering surface of the mirror group 30 does not form light cooperation with the first lens group 10, but receives externally incident light, the light received by the light entering surface of the mirror group 30 is transmitted to the second lens group 20 by the light exiting surface of the mirror group 30 for imaging, and the mirror group 30 reflects the external light to the second lens group 20, so as to realize the independent imaging of the second lens group 202 without changing the light transmission track of the first lens group 10.

As shown in fig. 5 and fig. 6, when the mirror assembly 30 is in the second working state, the light entrance surface of the mirror assembly 30 is located on the light transmission path of the first lens assembly 10, the light entrance surface can receive light passing through the first lens assembly 10, the light exit surface of the mirror assembly 30 transmits the light received by the light entrance surface to the second lens assembly 20 for imaging, so that the primary imaging output by the first lens assembly 10 is transmitted to the second lens assembly 20 through the mirror assembly 30, and the second lens assembly 20 processes the primary imaging for outputting secondary imaging.

Therefore, according to the lens module 100 of the embodiment of the present application, the reflecting mirror assembly 30 having two working states is disposed, so that the second lens group 20 can be independently imaged, and the second lens group 20 and the first lens group 10 can be cooperatively imaged, thereby realizing different lens combinations, improving the definition of the captured image or the width of the field of view, and further improving the utilization rate of the lens.

According to an embodiment of the present application, the mirror group 30 comprises a first mirror 31 and a second mirror 32.

Specifically, the first mirror 31 has a light-entering surface, and the first mirror 31 is movable in a first direction; the second reflector 32 has a light-emitting surface, the second reflector 32 is disposed opposite to the first reflector 31, and the second reflector 32 is movable in a first direction; in the case where the mirror group 30 is in the first state, the first mirror 31 and the second mirror 32 are respectively located between the first lens group 10 and the second lens group 20; in the case where the mirror group 30 is in the second state, the first mirror 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 mirror 32 is located in the light transmission path of the second lens group 20.

In other words, a horizontal moving rail 7 may be disposed inside one of the electronic devices, and as shown in fig. 1, 3 and 5, both the first reflecting mirror 31 and the second reflecting mirror 32 may slide horizontally between the horizontal moving rails 7, and both the first reflecting mirror 31 and the second reflecting mirror 32 may slide along the length direction (i.e., the first direction) of the horizontal moving rail 7.

As shown in fig. 1 and 2, in the state where the mirror group 30 is in the first state, the first mirror 31 can be slid on the horizontal movement guide 7 to an extreme position away from the first lens group 10, and the second mirror 32 can be slid on the horizontal movement guide 7 to an extreme position away from the second lens group 20, at which time the first lens group 10 and the second lens group 20 are in the closest position. Accordingly, both the first lens group 10 and the second lens group 20 can be in an idle state, and can also be in a state of being operated alone.

As shown in fig. 3 and 4, when the mirror assembly 30 is in the first working state, the second mirror 32 can slide on the horizontal moving guide 7 to a position close to the second lens assembly 20, and the light-exiting surface of the second mirror 32 faces the light-entering end of the second lens assembly 20. The first reflector 31 can transmit the external light to the second reflector 32, and then the external light is output to the second lens group 20 by the second reflector 32, so as to realize the independent imaging of the second lens group 20.

As shown in fig. 5 and 6, when the mirror assembly 30 is in the second operating state, the first mirror 31 is moved close to the first lens group 10, and the second mirror 32 is moved close to the second lens group 20, at this time, the light-entering surface of the first mirror 31 faces the light-exiting end of the first lens group 10, and the light-exiting surface of the second mirror 32 faces the light-entering end of the second lens group 20. The first lens group 10 can transmit external light to the first mirror 31, transmit the light passing through the first mirror 31 to the second mirror 32 and form an image on the second lens group 20.

Therefore, according to the lens module 100 of the embodiment of the present application, the spatial positions of the two reflectors are changed, on one hand, the first lens group 10 and the second lens group 20 are imaged separately or in combination, and on the other hand, in the state that the reflector group 30 does not work, the reflector group 30 is moved to the inner space of the electronic device and located between the first lens group 10 and the second lens group 20, so that the utilization rate of the inner space of the electronic device is improved.

According to one embodiment of the present application, the first mirror 31 and the second mirror 32 are prisms, respectively.

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, and the light outlet surface is disposed opposite to the light inlet surface.

In other words, the prisms can reflect the vertically input light rays out horizontally, such that the light rays can be reversed by the cooperation of the two prisms, as shown in fig. 3 and 4, and when the reflector assembly 30 is in the first working state, the external light rays input from the light input surface of the first reflector 31 can be output from the light output surface of the second reflector 32, so as to image the second lens group 20.

Referring to fig. 5 and 6, when the mirror group 30 is in the second operating state, the first mirror 31 moves to the light transmission path of the first mirror 31, and the first mirror 31 can receive the light passing through the first lens group 10 and output the light to the second lens 21 by the second mirror 32, so as to realize the combined imaging of the first lens 11 and the second lens 21.

Therefore, according to the lens module 100 of the embodiment of the present application, by using the optical characteristics of the prism, the first reflector 31 or the second reflector 32 moves to any position on the horizontal moving guide 7, and the light emitted through the first reflector 31 can be output to the optical incident surface of the second reflector 32, so that the situation that the light path of the first reflector 31 changes after the first reflector 31 or the second reflector 32 moves is reduced, and the imaging integrity of the second lens 21 is improved.

According to one embodiment of the present application, the first lens group 10 is movable in a second direction between a first initial position and a first operational position, and the second lens group 20 is movable in the second direction between a second initial position and a second operational position, wherein the second direction is perpendicular to the first direction.

Specifically, when the mirror 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; under the condition that the reflector group 30 is in the first working state, the first lens group 10 is located at the first initial position, the second lens group 20 is located at 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 intake end of the second lens group 20 in the second direction; when the reflector set 30 is in the second working state, the first lens group 10 is located at the first working position, the second lens group 20 is located at the second working position, the first reflector 31 is located at the light-emitting end of the first lens group 10 in the second direction, and the second reflector 32 is located at the light-entering end of the second lens group 20 in the second direction.

In other words, the electronic device is provided with a vertical moving rail 8 along the thickness direction thereof, as shown in fig. 1 and 5, the first lens group 10 and the second lens group 20 correspond to one vertical moving rail 8, 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 rail 8, and the horizontal moving rail 7 can also be provided in the electronic device, accordingly, the vertical moving rail 8 is perpendicular to the horizontal moving rail 7. The first lens 11 or the second lens 21 can extend out of the electronic device along the vertical moving guide rail 8, the extended limit position of the first lens 11 is a first working position, and the extended limit position of the second lens 21 is a second working position; the second lens 21 can also be retracted into the electronic device along the vertical moving guide 8, and the extreme position where the second lens 21 is retracted is the first initial position, and the extreme position where the second lens 21 is extended is the second initial position.

As shown in fig. 1 and 2, when the mirror 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 operate, or may start to operate independently.

As shown in fig. 3 and 4, when the reflector 30 is in the first working state, the first lens group 10 is located at the first initial position, the second lens group 20 is located at 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-in 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.

As shown in fig. 5 and 6, when the mirror assembly 30 is in the second working state, the first lens assembly 10 is located at the first working position, the second lens assembly 20 is located at the second working position, the first mirror 31 is located at the light emitting end of the first lens assembly 10 in the second direction, and the second mirror 32 is located at the light entering end of the second lens assembly 20 in the second direction, at this time, the first lens assembly 10 and the second lens assembly 20 can be combined through the mirror assembly 30 to realize the imaging of the common work.

Therefore, according to the lens module 100 of the embodiment of the present application, 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 the non-photographing mode, the first lens 11 and the second lens 21 are located in the electronic device, so as to effectively reduce the abrasion of the light-in ends of the first lens group 10 and the second lens group 20. When the electronic device is in a photographing mode, the light-in end of the first lens group 10 and/or the second lens group 20 extends out of the electronic device, so that the condition that the light of the first lens group 10 and/or the second lens group 20 in the electronic device is dim is reduced, and the imaging quality of the electronic device is improved.

In some embodiments of the present application, the first lens group 10 includes a first lens 11 and a first photo chip 12, the first lens 11 is movable, the first photo chip 12 is disposed at the light emitting end of the first lens 11, and the first reflector 31 is disposed between the first lens 11 and the first photo chip 12 when the reflector set 30 is in the second working state.

In other words, the first lens 11 can slide on the corresponding vertical moving guide rail 8, the first photosensitive chip 12 can be installed in the corresponding electronic device, and the first lens 11 can transmit external light to the first photosensitive chip 12, so that the first photosensitive chip 12 images light output by the first lens 11, where the first photosensitive chip 12 can be a light sensing chip. As shown in fig. 1, 3 and 5, when the mirror assembly 30 is in the first state or the first working state, the first mirror 31 is located at a side of the first lens 11 close to the second lens assembly 20, and the second lens assembly 20 can be imaged by the first mirror 31 and the second mirror 32. Under the condition that the reflector group 30 is in the second working state, the first reflector 31 is located between the first lens 11 and the first photo-sensing chip 12, and the first reflector 31 transmits the light passing through the first lens 11 to the second reflector 32, so that no image can be formed on the first photo-sensing chip 12.

Therefore, according to the lens module 100 of the embodiment of the present application, the first lens 11 slides on the vertical moving rail 8, and a cavity for placing the first reflector 31 is formed between the first lens 11 and the first light sensing chip 12, so as to realize the switching from the imaging of the second lens group 20 alone to the combined imaging of the first lens group 10 and the second lens group 20.

Optionally, according to an embodiment of the present 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 move synchronously, and the second photosensitive chip 22 is disposed at a light-emitting end of the second lens 21.

In other words, as shown in fig. 3 and fig. 5, the second lens 21 and the second photosensitive chip 22 may be adhered, welded, inserted and the like to achieve synchronous movement, which is not limited herein. The second photosensitive chip 22 is disposed at a light emitting end of the second lens 21 to realize imaging of light output by the second lens 21. When the second lens group 20 is imaged alone, external light can be input to the second lens 21 in the fourth direction through the mirror group 30 and imaged on the second photo-sensitive chip 22. When the first lens group 10 and the second lens group 20 are combined to form an image, light can be inputted into the second lens 21 from the same fourth direction through the mirror group 30. The fourth direction may be a direction entering along the optical axis of the second lens and toward the light-entering surface of the second lens.

Therefore, according to the lens module 100 in the embodiment of the present application, since the second lens 21 receives light from the fourth direction, the second lens 21 and the second sensor chip 22 move synchronously, that is, the distance between the second lens 21 and the second sensor chip 22 is relatively fixed, so that the second sensor chip 22 can be located at a better imaging position, and the imaging quality of the second lens group is further improved.

In some alternative embodiments of the present application, according to one embodiment of the present application, the first lens group 10 is a wide angle lens group, the second lens group 20 is a telephoto lens group, and a moving distance of the first lens group 10 is smaller than a moving distance of the second lens group 20 in the second direction.

In other words, the first lens 11 of the first lens group 10 may be a wide-angle lens, and the second lens 21 of the second lens group 20 may be a telephoto lens. As shown in fig. 1 and 2, when the mirror group 30 is in the first state, the wide-angle lens and the telephoto lens may be operated independently or not operated; as shown in fig. 3 and 4, when the mirror group 30 is in the first working state, the telephoto lens can work; as shown in fig. 5 and fig. 6, when the mirror assembly 30 is in the second working state, the wide-angle lens and the telephoto lens may cooperate to form a frazier lens, the telephoto lens may zoom in on a distant object, and the range of the wide-angle lens is wider.

Thus, according to the lens module 100 of the present embodiment, the first lens group 10 can be used for taking a long-range view as a wide-angle lens group, and the second lens group 20 can be used for taking a short-range view as a telephoto lens group, and the combination of the wide-angle lens group and the telephoto lens group through the mirror group 30 realizes a large wide-angle lens having a large imaging circle. When the field lens 4 is disposed 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 on the field lens 4, and then one telephoto lens group captures the image on the field lens 4 to realize zooming and control the aperture, so as to realize clear imaging of a far scene and a near scene.

According to one embodiment of the present application, the field lens 4 is provided between the first mirror 31 and the second mirror 32.

In other words, the field lens 4 may be disposed at an intermediate position between the first lens group 10 and the second lens group 20, with the incident surface of the field lens 4 disposed toward the light exit surface of the first reflector 31 and the transmitting surface of the field lens 4 disposed toward the light incident surface of the second reflector 32.

Therefore, according to the lens module 100 of the embodiment of the present application, when the first lens 11 and the second lens group 20 are combined to image, the field lens 4 can collect light passing through the edge of the first lens 11, reduce vignetting, and enlarge an intermediate image, so as to improve the quality of a captured image. When imaging on the second lens group 20 through the mirror group 30, the field lens 4 can collect light passing through the edge of the first mirror 31 to improve the image quality when the second lens group 20 is imaged alone.

Optionally, according to an embodiment of the present application, the lens module 100 further includes a first cover plate 5 and a second cover plate 6.

Specifically, the first cover plate 5 is movable in the third direction to block or avoid the light transmission of the first lens group 10; the second cover plate 6 can move in the third direction to block or avoid the light transmission of the second lens group 20; the second direction is respectively vertical to the first direction and the third direction.

In other words, the respective electronic devices may further be provided with glass moving rails 9, and the glass moving rails 9 may be simultaneously disposed perpendicular to the horizontal moving rails 7 and the vertical moving rails 8 so that the first cover 5 and the second cover 6 may slide on the corresponding glass moving rails 9. The first lens group 10 and the second lens group 20 both correspond to a glass moving rail 9, wherein the length of the glass moving rail 9 corresponding to the second lens group 20 is greater than that of the glass moving rail 9 corresponding to the first lens group 10, so as to realize that the glass moving rail 9 corresponding to the second lens group 20 can cover the light-in surface of the first reflector 31, and further when the second lens 21 and the first reflector 31 are both shielded by the glass moving rail 9, the first lens group 10 can work alone, or the first lens group 10 and the second lens group 20 can be combined for imaging, similarly, when the first lens group 10 is shielded by the glass moving rail 9, the second lens group 20 can work alone. When the first cover plate 5 and the second cover plate 6 are retracted simultaneously, the first lens group 10 and the second lens group 20 can work independently, or can work in combination through the mirror group 30.
