Referring to fig. 2 and 4, the image sensor 200 may be located at the end of the optical path. Specifically, the light is reflected by the third reflective element 70 and then converged onto the surface of the image sensor 200, and the image sensor 200 converts the converged light into an electrical signal for imaging. The image sensor 200 may be a Complementary Metal Oxide Semiconductor (CMOS) image sensor 200 or a Charge-coupled Device (CCD) image sensor 200 or other types of image sensors 200, but is not limited thereto. The image sensor 200 may be a visible light image sensor 200, an infrared image sensor 200, or other types of image sensors 200, and is not limited herein.
The first reflective element 10 may be a reflective prism or a mirror, wherein the reflective prism may be a reflective prism, a reflective pentaprism, or other types of reflective prisms, etc., without limitation.
With continued reference to fig. 2 and 4, in some embodiments, the second reflective element 50 may be a second reflector, and further, the second reflective element 50 may be a second reflector. The third reflective element 70 may be a third mirror, and further, the third reflective element 70 may be a third reflective plane mirror.

The third reflecting element 70 may be a third reflecting prism, and further, the third reflecting element 70 may be a third reflecting prism.
Referring to fig. 5 or fig. 6, in some embodiments, the second reflective element 50 and the third reflective element 70 can move in the same direction on the second optical axis O2 to change the converging position of the light reflected by the third reflective element 70, so that the anti-shake function of the optical lens 100, the camera module 1000, and the electronic device 2000 according to the embodiments of the present disclosure is realized through the moving mode in which the second reflective element 50 and the third reflective element 70 move in the same direction on the second optical axis O2, thereby avoiding the adverse effect on the imaging caused by the shake of the optical lens 100, the camera module 1000, or the electronic device 2000 during the imaging process, and improving the imaging definition.
Specifically, the movement on the second optical axis O2 includes movement in the first direction on the second optical axis O2 and movement in the second direction on the second optical axis O2.
Referring to fig. 1 and 5, the second reflective element 50 and the third reflective element 70 can both move in the first direction on the second optical axis O2, and at this time, the converging position of the light reflected by the third reflective element 70 on the plane perpendicular to the first optical axis O1 moves in the first direction, so that the imaging light of the optical lens 100, the camera module 1000, and the electronic device 2000 in the embodiment of the present application on the image sensor 200 generally moves in the first direction, for example, as shown in fig. 5, a certain image point P1 moves to a point P1' in the first direction. Here, the first direction may be a y direction shown in fig. 1 and 5, and the first direction may be parallel to the second optical axis O2.
Referring to fig. 1 and 6, the second reflective element 50 and the third reflective element 70 can move in the second direction on the second optical axis O2, and at this time, the converging position of the light reflected by the third reflective element 70 on the plane perpendicular to the first optical axis O1 moves in the second direction, so that the imaging light of the optical lens 100, the camera module 1000, and the electronic device 2000 in the embodiment of the present application on the image sensor 200 can move in the second direction as a whole, for example, as shown in fig. 6, a certain image point P2 moves to a point P2' in the first direction. Wherein the second direction may be parallel to the second optical axis O2 and opposite to the first direction. The second direction may be opposite to the y direction as shown in fig. 1 and 6. It is understood that during the process of capturing an image or video, the lens may have a certain degree of shake due to the user's hand or other environmental factors, and the shake may blur the captured image or video. According to the optical lens 100, the camera module 1000, or the electronic device 2000 of the embodiment of the present application, the second reflective element 50 and the third reflective element 70 are used to move towards the first direction or move towards the second direction on the second optical axis O2, so that the imaging light of the optical lens 100, the camera module 1000, and the electronic device 2000 of the embodiment of the present application on the image sensor 200 can move towards the first direction or move towards the second direction in the imaging process, thereby being helpful to correct the adverse effect on the imaging light caused by shaking in the imaging process, and being beneficial to improving the imaging definition and ensuring the definition of the captured image or video.
Preferably, the second reflective element 50 and the third reflective element 70 can move in the same direction on the second optical axis O2 by the same distance to change the converging position of the light reflected by the third reflective element 70. It should be noted that, when the second reflective element 50 and the third reflective element 70 move in the same direction and for the same distance on the second optical axis O2, as shown in fig. 5 or fig. 6, it is easy to understand that, since the moving direction and the moving distance of the second reflective element 50 and the third reflective element 70 are the same, the distance between the second reflective element 50 and the third reflective element 70 will be kept constant during the moving process, and the distance between the lens assembly 30 and the second reflective element 50 is the same as the distance between the image sensor 200 and the third reflective element 70, so the optical path length of the light from the lens assembly 30 to the image sensor 200 will be kept constant. The second reflective element 50 and the third reflective element 70 can move a same distance on the second optical axis O2 in the same direction to change the convergence position of the light reflected by the third reflective element 70, which is beneficial to avoiding the influence on the length of the optical path or the length of the focal length of the optical lens 100 when the anti-shake function of the optical lens 100, the camera module 1000, and the electronic device 2000 is implemented, thereby facilitating the improvement of the stability of the optical system of the optical lens 100, the camera module 1000, and the electronic device 2000.
As shown in fig. 1, the second reflective element 50 and the third reflective element 70 move along the second optical axis O2, and in some embodiments, move along the height direction (z direction) of the electronic device 2000 in fig. 1.
In some embodiments, the optical lens 100 may further include a gyroscope (not shown) or another displacement sensor (not shown), and the gyroscope or the other displacement sensor may be used to detect shake information of the optical lens 100, so that the optical lens 100, the camera module 1000, and the electronic device 2000 according to the embodiment of the present disclosure can implement the anti-shake function of the optical lens 100, the camera module 1000, and the electronic device 2000 according to a moving mode in which the second reflecting element 50 and the third reflecting element 70 move in the same direction on the second optical axis O2 according to the shake information.
Referring to fig. 7 in combination with fig. 1, fig. 5 and fig. 6, in some embodiments, the first reflective element 10 can rotate around a predetermined axis Y1 (parallel to the Y direction) of the first reflective element 10, and a converging position of the light reflected by the third reflective element 70 on a plane perpendicular to the first optical axis O1 moves toward the third direction or the fourth direction, so that the imaging light of the optical lens 100, the camera module 1000 and the electronic device 2000 of the present disclosure on the image sensor 200 can move generally toward the second direction. Wherein, the third direction may be a z direction; the fourth direction may be opposite to the z direction. Specifically, the first reflective element 10 can rotate counterclockwise around the preset axis Y1 of the first reflective element 10, and the converging position of the light reflected by the third reflective element 70 on the plane perpendicular to the first optical axis O1 moves toward the third direction, i.e., the z direction; the first reflecting element 10 can rotate counterclockwise around the predetermined axis Y1 of the first reflecting element 10, and the converging position of the light reflected by the third reflecting element 70 on the plane perpendicular to the first optical axis O1 moves toward the fourth direction, i.e., the direction opposite to the z direction. Further, the preset axis Y1 may be a central axis of the first reflective element 10, that is, the first reflective element 10 may have rotational symmetry about the preset axis Y1. The optical lens 100, the camera module 1000, or the electronic device 2000 of some embodiments of the present application can rotate around the preset axis Y1 of the first reflective element 10 by using the first reflective element 10, so that the imaging light on the image sensor 200 of the optical lens 100, the camera module 1000, and the electronic device 2000 of some embodiments of the present application can move generally toward the third direction or generally toward the fourth direction during the imaging process, thereby helping to correct the adverse effect on the imaging light caused by shake during the imaging process, and helping to improve the imaging definition.
Referring to fig. 8 or fig. 9, in some embodiments, the second reflective element 50 and the third reflective element 70 can move in opposite directions on the second optical axis O2 to change the overall focal length of the optical lens 100, so that a plane formed by the light reflected by the third reflective element 70 (i.e. an image plane of the optical lens 100) just falls on a plane where the image sensor 200 is located, thereby implementing a focusing function and ensuring that the formed image is clear. From another perspective, it can be seen that the embodiment changes the overall focal length of the optical lens 100 by the movement pattern of the second reflective element 50 and the third reflective element 70 moving in opposite directions on the second optical axis O2, and also, when the focal length of the lens assembly 30 is not changed, changes the optical path between the image sensor 200 and the lens assembly 30, so that the plane formed by the light reflected by the third reflective element 70 (i.e. the imaging surface of the optical lens 100) can just fall on the plane of the image sensor 200, thereby enabling the optical lens 100, the camera module 1000, or the electronic device 2000 according to some embodiments of the present application to implement a focusing function, and ensuring that the image is clear.
Specifically, the movement on the second optical axis O2 includes movement in the first direction on the second optical axis O2 and movement in the second direction on the second optical axis O2.
In the embodiment shown in fig. 8 and 9, when the second reflecting element 50 is moved toward the first direction on the second optical axis O2 and the third reflecting element 70 is moved toward the second direction on the second optical axis O2, the overall focal length of the optical lens 100 increases. Wherein the first direction and the second direction may both be parallel to the second optical axis O2, and the first direction is opposite to the second direction. Further, when the second reflecting element 50 is moved toward the second direction on the second optical axis O2 and the third reflecting element 70 is moved toward the first direction on the second optical axis O2, the overall focal length of the optical lens 100 is decreased. Wherein the first direction and the second direction may both be parallel to the second optical axis O2, and the first direction and the second direction are also opposite. The first direction may be the y direction shown in fig. 8, 9 and 1, and the second direction may be the opposite direction to the y direction shown in fig. 8, 9 and 1. The image sensor 200 may be disposed on a first side of the first optical axis O1, the first side being a side of the first optical axis O1 that is away from the y-direction, i.e., a side facing the opposite direction of the y-direction. In another aspect, the optical lens 100 (shown in fig. 8), the camera module 1000, or the electronic device 2000 of some embodiments of the present application can be regarded as increasing the optical path between the image sensor 200 and the lens assembly 30 under the condition that the focal length of the lens assembly 30 is not changed by moving the second reflecting element 50 toward the first direction on the second optical axis O2 and moving the third reflecting element 70 toward the second direction on the second optical axis O2, so that the plane formed by the light reflected by the third reflecting element 70 (i.e., the imaging plane of the optical lens 100) can just fall on the plane of the image sensor 200, and thus the optical lens 100, the camera module 1000, or the electronic device 2000 of some embodiments of the present application can realize the focusing function, and ensure that the formed image is clear. Similarly, the optical lens 100 (shown in fig. 9), the camera module 1000, or the electronic device 2000 of some embodiments of the present application can be regarded as reducing the optical path between the image sensor 200 and the lens assembly 30 when the focal length of the lens assembly 30 is unchanged by using the second reflective element 50 to move towards the second direction on the second optical axis O2 and the third reflective element 70 to move towards the first direction on the second optical axis O2, so that the plane formed by the light reflected by the third reflective element 70 (i.e. the image plane of the optical lens 100) can just fall on the plane of the image sensor 200, and thus the optical lens 100, the camera module 1000, or the electronic device 2000 of some embodiments of the present application can realize the focusing function to ensure that the image is clear.
In further embodiments, when the second reflective element 50 is moved toward the first direction on the second optical axis O2 and the third reflective element 70 is moved toward the second direction on the second optical axis O2, the overall focal length of the optical lens 100 increases. Further, when the second reflecting element 50 is moved toward the second direction on the second optical axis O2 and the third reflecting element 70 is moved toward the first direction on the second optical axis O2, the overall focal length of the optical lens 100 is decreased. The first direction is opposite to the second direction, specifically, the first direction may be opposite to the y direction shown in fig. 1, and the second direction may be the y direction shown in fig. 1. At this time, the image sensor 200 may be disposed on a second side of the first optical axis O1, the second side being a side of the first optical axis O1 facing the y direction. .
The optical lens 100, the camera module 1000 and the electronic device 2000 of some embodiments may first utilize the second reflective element 50 and the third reflective element 70 to move in the same direction on the second optical axis O2, so as to change the converging position of the light reflected by the third reflective element 70 on the image sensor 200, thereby achieving the anti-shake effect; the second reflective element 50 and the third reflective element 70 move in different directions on the second optical axis O2 to change the overall focal length of the optical lens 100, thereby achieving the focusing function. The anti-shake process (i.e., the moving process in which the second reflective element 50 and the third reflective element 70 move in the same direction on the second optical axis O2, which is the same as the moving process below) and the focusing process (i.e., the moving process in which the second reflective element 50 and the third reflective element 70 move in different directions on the second optical axis O2, which is the same as the moving process below) are realized in a time-sharing manner, so that the coupling degree between the anti-shake process and the focusing process can be reduced, interference caused by the anti-shake process to the focusing process can be avoided, interference caused by the focusing process to the anti-shake process can be avoided, the focusing effect and the anti-shake effect of the optical lens 100, the camera module 1000, and the electronic device 2000 according to the embodiments of the present disclosure can be better realized, and the stability of the optical system can be improved. Preferably, the optical lens 100, the camera module 1000, and the electronic device 2000 of the embodiment of the present disclosure may perform a focusing process first, and then perform an anti-shake process, so that a plane formed by light reflected by the third reflecting element 70 (i.e., an imaging plane of the optical lens 100) can just fall on a plane where the image sensor 200 is located, and then adjust the imaging light on the image sensor 200 to move towards one or more of the first direction, the second direction, the third direction, or the fourth direction, so as to correct shake in real time, which is beneficial to enabling the optical lens 100, the camera module 1000, and the electronic device 2000 of the embodiment of the present disclosure to achieve a better anti-shake effect.
In some embodiments, the optical lens 100, the camera module 1000 and the electronic device 2000 may further include a driving device. The driving device may include an electrostatic actuator device, an electromagnetic actuator device, a magnetostrictive actuator device, a piezoelectric motor, a stepping motor, an electroactive polymer actuator device, and the like, without limitation. The driving device may drive one or more of the first reflective element 10, the second reflective element 50, and the third reflective element 70 to move, so as to facilitate an anti-shake process and/or a focusing process of the optical lens 100, the camera module 1000, and the electronic device 2000 according to the embodiment of the present disclosure.
In some embodiments, referring to fig. 9, the optical lens 100 further includes a housing 90, and the housing 90 is used for accommodating and mounting the optical lens 100.
