[0002] In the related art, an optical lens can be set in a camera module, and the camera module can be installed on an electronic device to provide the electronic device with a corresponding shooting function. Taking the electronic device as an example, the telephoto camera module in the current mobile phone has achieved 10x optical zoom, and 5x periscope optical zoom has begun to become popular, and users' demand for telephoto lenses is also increasing. The current optical zoom solution mainly relies on switching back and forth between camera modules of different focal lengths, and because the periscope is in front, the diaphragm (aperture) of the optical system is set behind the periscope. The size of the aperture will be limited by the thickness of the mobile phone, and there is no way to make it larger, resulting in low light intake, low diffraction limit of light and other adverse effects. Summary of the Invention

[0003] To overcome the problem in related art that the aperture size is limited by the thickness of the mobile phone and cannot be enlarged, resulting in low light intake and low diffraction limit of light, the present disclosure provides an optical lens, a camera module and an electronic device.

[0004] According to a first aspect of an embodiment of the present disclosure, there is provided an optical lens, comprising:

[0005] An aperture, a zoom lens group, a light deflection assembly, and a compensation lens group are arranged in sequence along the optical axis from the object side to the imaging surface;

[0006] The optical axis forms a first optical axis segment between the aperture and the light deflecting assembly, and the zoom lens group is located on the first optical axis segment;

[0007] The optical axis forms a second optical axis segment between the light deflection component and the compensation lens group;

[0008] Wherein, the first optical axis segment is different from the second optical axis segment.

[0009] Optionally, the light deflection component includes:

[0010] A light incident surface that is perpendicular to the first optical axis segment, and a light exit surface that is perpendicular to the second optical axis segment.

[0011] Optionally, the light incident surface of the light deflection assembly and the light emitting surface of the light deflection assembly are perpendicular to each other.

[0012] Optionally, the zoom lens group includes:

[0013] at least one varifocal lens;

[0014] a first driving assembly connected to the at least one variable focus lens;

[0015] Wherein, the first lens optical axis formed by the optical center of the at least one zoom lens and the first optical axis segment are located on the same straight line.

[0016] Optionally, the optical lens further includes:

[0017] a second driving assembly connected to the compensation lens group;

[0018] Wherein, the second lens optical axis of the compensation lens group and the second optical axis segment are located on the same straight line.

[0019] Optionally, the aperture includes:

[0020] A light-transmitting hole, wherein the aperture of the light-transmitting hole is greater than or equal to the maximum diameter of the zoom lens included in the zoom lens group.

[0021] According to a second aspect of an embodiment of the present disclosure, a camera module is provided, comprising the optical lens according to any one of the first aspects, and further comprising:

[0022] The image sensor is located on a side of the compensation lens group away from the light deflection component.

[0023] Optionally, the camera module further includes:

[0024] The filter component is located between the compensation lens group and the image sensor.

[0025] Optionally, the camera module further includes:

[0026] The light-transmitting cover plate is located on the side of the aperture facing away from the zoom lens group.

[0027] According to a third aspect of an embodiment of the present disclosure, an electronic device is provided, comprising the camera module described in the second aspect.

[0028] The technical solutions provided by the embodiments of the present disclosure may have the following beneficial effects:

[0029] As can be seen from the above embodiments, the optical lens of the present disclosure includes an aperture, a zoom lens group, a light deflection assembly, and a compensating lens group arranged in sequence along the optical axis from the object side to the imaging surface, and the first optical axis segment formed between the aperture and the light deflection assembly is different from the second optical axis segment formed between the light deflection assembly and the compensating lens group.

[0030] Because the aperture is closest to the object side and located at the very front of the entire optical lens, adjusting the aperture size is not restricted by the sizes of other components on the first optical axis segment. Furthermore, because the second optical axis segment is different from the first, adjusting the aperture size on the first optical axis segment is also not restricted by the sizes of components on the second optical axis segment. This allows the aperture size to be increased as needed to improve light intake and the diffraction limit, without being restricted by the sizes of other components.

[0046] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0047] Figure 1 is a schematic diagram of the structure of an optical lens according to an exemplary embodiment Figure 1 ,like Figure 1 As shown, the optical lens may include:

[0048] An aperture 101, a zoom lens group 102, a light deflection assembly 103, and a compensation lens group 104 are arranged in sequence along the optical axis from the object side to the imaging plane;

[0049] The optical axis forms a first optical axis segment between the aperture 101 and the light deflecting assembly 103 , and the zoom lens group 102 is located on the first optical axis segment;

[0050] The optical axis forms a second optical axis segment between the light deflection component 103 and the compensation lens group 104;

[0051] Wherein, the first optical axis segment is different from the second optical axis segment.

[0052] Here, the aperture can be an element used to constrain and limit the incident light. For example, it can be a frame of a set size set at the front end of the zoom lens group. In some optional embodiments, the light deflection component can be a prism, or it can be other devices that change the propagation direction of the incident light. In some embodiments, the light deflection component can include: a prism. Here, a prism is a transparent body with a triangular cross-section in optics, and is an optical instrument with a triangular cross-section made of transparent material. In other embodiments, the light deflection component can also be a prism of other shapes, such as a quadrangular prism, a pentaprism, etc., which are not specifically limited here.

[0053] During the implementation process, the incident light can be transmitted through the aperture to the zoom lens group. After receiving the incident light, the zoom lens group can transmit the incident light to the light deflection component. After receiving the incident light, the light deflection component can deflect the incident light to the compensation lens group.

[0054] In the embodiment of the present disclosure, a first optical axis segment is formed between the aperture and the light deflection assembly, and the zoom lens group is located on the first optical axis segment, that is, the aperture and the light deflection assembly are located on both sides of the zoom lens group. In the embodiment of the present disclosure, the optical axis can be a line passing through the lens center of the zoom lens group and the lens center of the compensation lens group. The first optical axis segment can be a line segment that starts from the aperture, ends at the light deflection assembly, passes through the lens center of the zoom lens group, and is perpendicular to the light incident surface of the zoom lens group. The second optical axis segment can be a line segment that starts from the light deflection assembly, ends at the compensation lens group, passes through the lens center of the compensation lens group, and is perpendicular to the light incident surface of the compensation lens group.

[0055] In some embodiments, when the light deflection assembly has multiple sides, the compensating lens group and the zoom lens group can be located on different sides of the light deflection assembly. For example, the compensating lens group can be located on a first side of the light deflection assembly, and the zoom lens group can be located on a second side of the light deflection assembly, with the first side and the second side being perpendicular to each other. Furthermore, since the compensating lens group is located on the second optical axis segment and the zoom lens group is located on the first optical axis segment, if the first and second sides of the light deflection assembly are perpendicular to each other, the first and second optical axis segments are also perpendicular to each other.

[0056] For another example, the compensating lens group may be located on a first side of the light deflection assembly, and the zoom lens group may be located on a second side of the light deflection assembly, with the first and second sides being at a 50-degree angle relative to each other. Furthermore, since the compensating lens group is located on the second optical axis segment and the zoom lens group is located on the first optical axis segment, when the first and second sides of the light deflection assembly are at a 50-degree angle relative to each other, the first and second optical axis segments also form a 50-degree angle relative to each other. In other embodiments, the relationship between the first and second sides may be determined based on the shape of the light deflection assembly, which is not specifically limited herein.

[0057] In some embodiments, a plurality of compensating lenses can be provided within the compensating lens assembly. These lenses are lenses that can form a predetermined light transmission path. After incident light enters the compensating lens assembly, it can be transmitted along the predetermined light transmission path. In other embodiments, the compensating lens assembly can be composed of a single convex lens or a single concave lens. In still other embodiments, the compensating lens assembly can be composed of a combination of convex and concave lenses.

[0058] For example, the compensating lens group may include a first compensating lens, a second compensating lens, and a third compensating lens. The first compensating lens has a convex light-entry surface and a concave light-exit surface. The second compensating lens has a convex light-entry surface and a concave light-exit surface. The third compensating lens has a concave light-entry surface and a concave light-exit surface. During implementation, the first, second, and third compensating lenses can form a predetermined light transmission path. After incident light enters the compensating lens group, it can be transmitted along the predetermined light transmission path.

[0059] In other embodiments, the compensating lens group can be moved to compensate for the incident light output from the light deflection assembly, thereby assisting the zoom lens group in zooming. To ensure that the set light transmission path remains unchanged, the individual compensating lenses in the compensating lens group can be moved simultaneously. For example, if the incident light is relatively divergent, more of the divergent light can be focused to improve the quality of the resulting target image.

[0060] Figure 2A It is a schematic diagram of the structure of an optical lens in a 3x zoom mode in the related art. Figure 2B It is a schematic diagram of the structure of an optical lens in a 4x zoom mode in the related art. Figure 2C FIG. 1 is a schematic diagram of the structure of an optical lens in a 5x zoom mode in the related art, such as Figures 2A to 2C As shown, in the related art, the prism 201 is set at the front end of the entire optical system 202. In this way, since the lenses in the optical system 202 need to be placed vertically, the diaphragm (aperture) 203 is located at the front end of the optical system. When the diaphragm 203 and the display screen of the electronic device are perpendicular to each other, if the aperture is to be made larger, the thickness of the electronic device needs to be increased to provide enough space for the aperture, but this will make the electronic device very thick and heavy.

[0061] In the embodiment of the present disclosure, compared with Figures 2A to 2CThe technical solution in [1] positions the diaphragm closest to the object by placing the zoom lens group between the aperture and the light deflection assembly. This ensures that incident light passes through the aperture before entering the zoom lens group and the light deflection assembly. Because the aperture is closest to the object and located at the very front of the entire optical lens, increasing the aperture size does not require a corresponding increase in the size of other components. This allows the aperture size to be increased as needed, increasing light intake and achieving the diffraction limit without being restricted by the size of other components.

[0062] In some embodiments, the light deflection assembly comprises:

[0063] A light incident surface that is perpendicular to the first optical axis segment, and a light exit surface that is perpendicular to the second optical axis segment.

[0064] Figure 3 is a schematic diagram of a cross-sectional structure of a prism according to an exemplary embodiment. Figure 3 As shown, the prism may include a light incident surface 301, a light deflecting surface 302, and a light emitting surface 303. During implementation, the prism may receive incident light based on the light incident surface, and after receiving the incident light, refract the incident light based on the light deflecting surface to change the transmission direction of the incident light, and then output the incident light with the changed transmission direction based on the light emitting surface.

[0065] In some optional embodiments, the light incident surface of the prism can be perpendicular to the light emitting surface, and the light deflection surface 302 forms a 45-degree angle with the light incident surface and the light emitting surface, respectively. In this way, when the prism receives incident light perpendicular to the light incident surface 301, the direction of the incident light can be changed to a direction parallel to the light incident surface 301 after passing through the prism.

[0066] For example, if the aperture is located in the XOY plane of a Cartesian coordinate system, increasing the aperture size during implementation simply requires occupying more area on the XOY plane without increasing the height along the Z axis. This way, if the electronic device's display is also located in the XOY plane of a Cartesian coordinate system, the thickness of the electronic device will not increase.

[0067] In the disclosed embodiment, the aperture and the zoom lens group can be arranged on the light incident side of the light deflection assembly. Since the aperture is located at the front end of the light deflection assembly, the size of the aperture can be increased as needed without increasing the thickness of the electronic device.

[0068] In some embodiments, the light incident surface of the light deflection assembly and the light exit surface of the light deflection assembly are perpendicular to each other. In some embodiments, when the optical lens is applied to an electronic device with a display screen, the light incident surface of the light deflection assembly can be parallel to the display screen of the electronic device, and the light exit surface of the light deflection assembly can be perpendicular to the light exit surface of the display screen of the electronic device.

[0069] In other embodiments, the light entrance surface of the aperture for receiving incident light is parallel to the light entrance surface of the light deflection assembly. In this way, the light entrance surface of the aperture can be made parallel to the display screen of the electronic device, and when the size of the aperture needs to be increased, the thickness of the electronic device will not be increased.

[0070] In some embodiments, the optical axis of the first lens of the zoom lens group and the optical axis of the second lens of the compensating lens group are perpendicular to each other. In the disclosed embodiments, by making the optical axis of the first lens of the zoom lens group perpendicular to the optical axis of the second lens of the compensating lens group, when the light incident surface of the light deflection assembly and the light exit surface of the light deflection assembly are perpendicular to each other, the incident light deflected by the light deflection assembly can be successfully deflected to the compensating lens group, and the optical zoom function of the camera module can be achieved by moving the compensating lens group.

[0071] In some embodiments, the zoom lens assembly includes:

[0072] at least one varifocal lens;

[0073] a first driving assembly connected to the at least one variable focus lens;

[0074] Wherein, the first lens optical axis formed by the optical center of the at least one zoom lens and the first optical axis segment are located on the same straight line.

[0075] Here, the individual zoom lenses in the at least one zoom lens are arranged sequentially along the first lens optical axis of the zoom lens group, and the zoom lenses are spaced apart from each other. In some embodiments, the optical centers of the multiple zoom lenses are located on the same straight line, forming the first lens optical axis of the zoom lens group. During implementation, the distance between any two adjacent zoom lenses can be changed. In the disclosed embodiments, the focal length of the camera module can be adjusted by changing the distance between any two adjacent zoom lenses in the multiple zoom lenses.

[0076] Here, the first drive assembly may include a guide rail parallel to the optical axis of the first lens, and the guide rail is slidably connected to the multiple zoom lenses. The first drive assembly may be composed of a drive motor, for example, a linear motor, a rotor motor, or other drive motor. In the embodiment of the present disclosure, by providing the first drive assembly on the zoom lens group, the zoom lens can be driven to move based on the first drive assembly, thereby achieving optical zoom of the camera module.

[0077] In some embodiments, the camera module further includes:

[0078] a second driving assembly connected to the compensation lens group;

[0079] Wherein, the second lens optical axis of the compensation lens group and the second optical axis segment are located on the same straight line.

[0080] In other embodiments, the compensating lens group can be moved to compensate for the incident light output from the light deflection assembly, thereby assisting the zoom lens group in zooming. To ensure that the set light transmission path remains unchanged, the individual compensating lenses in the compensating lens group can be moved simultaneously. For example, if the incident light is relatively divergent, more of the divergent light can be focused to improve the quality of the resulting target image.

[0081] Figure 4 FIG. 1 is a schematic structural diagram of a compensation lens assembly according to an exemplary embodiment. Figure 4 As shown, the compensating lens group 104 may have a plurality of lenses 401 .

[0082] Here, the second drive assembly may include a guide rail parallel to the optical axis of the second lens, and the guide rail is slidably connected to the compensating lens group. The second drive assembly may be composed of a drive motor, for example, a linear motor, a rotor motor, or other drive motor. In the disclosed embodiment, by providing a second drive assembly on the compensating lens group, the compensating lens group can be driven to move based on the second drive assembly, thereby compensating for incident light and achieving optical zoom together with the zoom lens group.

[0083] In some embodiments, the aperture comprises:

[0084] A light-transmitting hole, wherein the aperture of the light-transmitting hole is greater than or equal to the maximum diameter of the zoom lens included in the zoom lens group. Here, by providing a light-transmitting hole in the diaphragm and making the aperture of the light-transmitting hole greater than or equal to the maximum diameter of the zoom lens included in the zoom lens group, the amount of light entering the zoom lens group can be increased.

[0085] Figure 5A The structure of the camera module is shown in accordance with an exemplary embodiment. Figure 1 As shown in FIG5 , the camera module includes an optical lens and further includes:

[0086] The image sensor 105 is located on a side of the compensation lens group of the optical lens away from the light deflection component.

[0087] In the embodiment of the present disclosure, the image sensor is arranged on a side of the compensation lens group away from the light deflection component to receive the incident light output by the compensation lens group 104 and form a target image based on the image sensor.

[0088] In some embodiments, the camera module further includes:

[0089] The filter component 501 is located between the compensation lens group and the image sensor.

[0090] Figure 5B 2 is a structural diagram of a camera module according to an exemplary embodiment. Figure 5B As shown, the filter component 501 is located between the compensation lens group 104 and the image sensor 105 .

[0091] Here, the filter assembly can be used to filter out light within a set wavelength band. In some embodiments, the camera module may further include: a filter assembly for filtering out infrared light, located on the light-emitting side of the compensating lens group. In the disclosed embodiment, a filter assembly can be provided between the compensating lens group and the image sensor to filter out infrared light. For example, an infrared filter can be provided between the compensating lens group and the image sensor. Here, the infrared filter assembly can filter out infrared light to prevent the image sensor from sensing invisible light, thereby preventing ghosting or flare from forming during imaging and affecting image quality.

[0092] In some embodiments, the camera module further includes:

[0093] The light-transmitting cover plate is located on the side of the aperture facing away from the zoom lens group.

[0094] Figure 6 The structure of the camera module is shown in accordance with an exemplary embodiment. Figure 3 ,like Figure 6 As shown, a transparent cover plate 601 can be provided on the side of the aperture 101 facing away from the zoom lens group 102. The transparent cover plate is waterproof and dustproof to protect the component structure inside the camera module from damage.

Figure 7B is a structural diagram of a camera module in 4x zoom mode according to an exemplary embodiment.

That is, the zoom lens in the zoom lens group can move in a first direction, and the compensating lens group can move in a second direction. The first direction can be the direction of the optical axis of the first lens in the zoom lens group, which can be the up-down direction as shown in the figure, and the second direction can be the direction of the optical axis of the second lens in the compensating lens group, which can be the left-right direction as shown in the figure. In the disclosed embodiment, the user can enlarge the aperture as needed without being limited by the size of the lenses and light deflection components in the zoom lens group, thereby increasing the amount of light entering and the diffraction limit of light.

[0096] In some embodiments, the electronic device is installed with a camera module as described in any of the above embodiments.

[0097] In the embodiment of the present disclosure, the camera module can be set in an electronic device, wherein the electronic device can include a mobile terminal and a fixed terminal. The mobile terminal can include a mobile phone, a laptop computer, a tablet computer, a wearable electronic device, etc., and the fixed terminal can include a personal computer device, a monitoring device, or a medical device, etc. The electronic device involved in the embodiment of the present disclosure includes a display module, wherein the display module can be a display screen of the electronic device. In the case where the electronic device includes a display screen, the light incident surface of the light deflection assembly can be parallel to the display screen of the electronic device, and the light exit surface of the light deflection assembly can be perpendicular to the display screen of the electronic device.
