The present application will now be described more fully hereinafter with reference to the accompanying drawings.

Referring to fig. 1 and fig. 2, fig. 1 and fig. 2 show schematic diagrams of a zoom lens 100 according to some embodiments of the present application, where the zoom lens 100 has an object side and an image side which are oppositely disposed, and light enters the zoom lens 100 from the object side of the zoom lens 100 and exits from the image side of the zoom lens 100. The zoom lens 100 has a refractive power, can adjust light rays, and has a zooming function, and the light rays can better converge on an imaging surface to form an image by adjusting the focal length of the zoom lens 100, so that more different shooting requirements are met. Specifically, the zoom lens 100 includes a support 110, a deformation element 120, a light-transmissive soft element 130, and a transparent cover plate 140. The bracket 110 includes a top wall 111 and a bottom wall 112 disposed opposite to each other, the top wall 111 faces the object side, and the bottom wall 112 faces the image side. The deformable element 120 is disposed on the image side of the bracket 110, and a portion of the deformable element 120 is attached to the bottom wall 112, and an opening 121 is disposed at a middle portion of the deformable element 130 to expose a portion of the light-transmissive flexible element 130. The frame 110 is surrounded to form an accommodating cavity 113, the transparent flexible element 130 is located in the accommodating cavity 113, and has an object-side surface facing the object side and an image-side surface facing the image side, and the image-side surface of the transparent flexible element 130 is attached to the surface of the deformable element 120. The transparent cover plate 140 is made of a transparent material, and the image side surface of the transparent cover plate 140 is attached to the object side surface of the transparent flexible element 130, and at least one of the object side surface and the image side surface of the transparent cover plate is provided with a filter film 141, so that the transparent cover plate 140 has a function of filtering out interference light.

In the zoom lens 100, the transparent flexible element 130 has refractive power and is capable of adjusting light. The shape of the deformation element 120 can be changed according to the change of the voltage applied to the deformation element 120, and when the shape of the deformation element 120 is changed, the shape of the transparent flexible element 130 is changed, so as to change the focal length of the transparent flexible element 130, thereby implementing the zoom function of the zoom lens 100. The supporting member can provide supporting and protecting functions for the deformation element 120 and the light-transmitting flexible element 130 disposed in the accommodating cavity 113. In addition, the transparent cover plate 140 can provide a supporting function for the transparent flexible element 130, and at least one of the object side surface and the image side surface of the transparent cover plate 140 is provided with the filter film 141, so that interference light in light entering the transparent flexible element 130 through the transparent cover plate 140 can be filtered, and the imaging quality of the zoom lens 100 is improved. It can be understood that the filter film 141 is disposed on the transparent cover plate 140, so that the zoom lens 100 can have a filtering function without additionally disposing a filter, thereby being beneficial to shortening the size of the zoom lens 100 and improving the space utilization of the zoom lens 100.

Of course, the type of the filter film 141 is not limited to be specific and can be selected according to the actual application requirement. For example, in some embodiments, the zoom lens 100 is used in the field of image capture, and here, the filter 141 may be an infrared cut filter for filtering out infrared rays and preventing the infrared rays from reaching the image plane and interfering with normal image capture. Moreover, in some embodiments, one of the object-side surface and the image-side surface of the transparent cover plate 140 is provided with the filter film 141, and the other is provided with the antireflection film (AR film), so that on the premise of not increasing the size of the zoom lens 100, the transmittance of the zoom lens 100 for light rays can be improved, and the space utilization rate of the zoom lens 100 is further improved. For example, in some embodiments, the transparent cover plate 140 has a filter film 141 disposed on the object side and an anti-reflective film disposed on the image side. In other embodiments, an antireflection film is disposed on the object side of the transparent cover plate 140, and a filter film 141 is disposed on the image side. It is understood that the antireflection film and the filter film 141 can be disposed on the object side or the image side of the transparent cover 140 by sputtering or the like. Of course, in other embodiments, the object-side surface and the image-side surface of the transparent cover plate 140 may also be provided with the filter film 141 to improve the filtering performance of the zoom lens 100.

More specifically, in some embodiments, the accommodating cavity 113 penetrates through the top wall 111 and the bottom wall 112, and the light-transmissive flexible element 130 is located in the accommodating cavity 113 and spaced apart from the bracket 110. When the deformation element 120 is not deformed, the image-side surface of the transparent flexible element 130 is flush with the bottom wall 112 of the bracket 110, the deformation element 120 is attached around the image-side surface of the transparent flexible element 130 to form the opening 121, meanwhile, the deformation element 120 extends to the bottom wall 112 toward the bracket 110, and the edge portion of the deformation element 120 is attached to the bottom wall 112, so that the transparent flexible element 130 is fixed in the bracket 110. The transparent cover 140 is disposed on a side of the transparent flexible element 130 away from the deformation element 120. It is understood that, by disposing the transparent flexible element 130 in the support 110, the support 110 can provide a supporting function for the deformable element 120, and at the same time provide a supporting and protecting function for the transparent flexible element 130. The transparent flexible element 130 is spaced apart from the frame 110, and the transparent flexible element 130 is not interfered by the frame 110 when deformed. Moreover, in some embodiments, the shape of the light-transmissive flexible element 130 is substantially square, and the side surfaces of the light-transmissive flexible element 130 are all recessed inward to form a concave arc surface. The material of the transparent flexible element 130 may be a polymer material.

Further, referring to fig. 1 and 2, in some embodiments, the shape changing element 120 is a piezoelectric film, and the opening 121 of the shape changing element 120 is circular. And both ends of the deformation element 120 are further provided with a positive electrode 122 and a negative electrode 123 to supply power to both ends of the deformation element 120. Specifically, in some embodiments, two positive electrodes 122 may be disposed, and two positive electrodes 122 are disposed on two sides of one end of the deformation element 120, and two negative electrodes 123 may be disposed, and two negative electrodes 123 are disposed on two sides of the other end of the deformation element 122. It should be noted that, when different voltages are applied to the two ends of the deformation element 120, the deformation element 120 may distort and deform, so as to drive the edge portion of the transparent flexible element 130 to distort and deform, and the distortion deformation of the edge portion of the transparent flexible element 130 may also drive the middle portion of the transparent flexible element 130 to bend, so as to change the focal length of the transparent flexible element 130, thereby implementing the zoom function of the zoom lens 100. It should be noted that, because the transparent cover plate 140 is attached to the object-side surface of the transparent flexible element 130, when the transparent flexible element 130 is deformed, the surface of the transparent flexible element 130 away from the transparent cover plate 140 is bent, and the surface of the transparent flexible element 130 facing the transparent cover plate 140 is not bent, and when the transparent flexible element 130 is deformed, the thickness of the transparent flexible element 130 is also changed, so as to drive the transparent cover plate 140 to move toward the direction close to or away from the deformable element 120 in the accommodating cavity 113.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating a camera module 200 according to some embodiments of the present application, where the camera module 200 includes an imaging element 210, a photosensitive element 230, and the zoom lens 100 according to any of the embodiments. Specifically, the imaging element 210 is disposed on the object side of the zoom lens 100, and includes an imaging lens 211, where the imaging lens 211 includes at least one lens with refractive power, so that the imaging element 210 has a light ray adjusting capability. The imaging assembly 210 and the zoom lens 100 are coaxially disposed, the photosensitive element 230 is disposed on the image side of the zoom lens 100, and the imaging assembly 210 and the zoom lens 100 cooperate to better adjust light rays, so that the light rays converge on the photosensitive surface of the photosensitive element 230 for imaging. By adopting the zoom lens 100 in the camera module 200, the camera module 200 can have a light filtering function without additionally configuring a light filter, so that the space utilization rate in the camera module 200 can be improved, and the size of the camera module 200 can be reduced.

In some embodiments, the camera module 200 further includes a circuit board 250 and a supporting base 260, and the light sensing element 230 is attached to the circuit board 250 and electrically connected to the circuit board 250 to convert image information formed on the light sensing element 230 into an electrical signal for outputting. The supporting base 260 covers the photosensitive element 230 to protect the photosensitive element 230, the zoom lens 100 is mounted on the supporting base 260, one end of the supporting base 260 away from the zoom lens 100 is fixedly connected to the circuit board 250, and the imaging component 210 can be connected to the supporting base 260. In addition, in some embodiments, the circuit board 250 further includes an electronic component 251, such as a capacitor resistor, and the electronic component 251 is disposed at a position away from the position where the photosensitive component 230 is disposed, so as to avoid interference with the image formed on the photosensitive component 230.

Further, in some embodiments, a fixing glue 240 is dotted at the edge of the photosensitive element 230, and the fixing glue 240 connects the photosensitive element 230 and the circuit board 250. Through the above design, the fixing glue 240 makes the photosensitive element 230 more firmly connected to the circuit board 250. Meanwhile, the fixed glue 240 is disposed at the edge of the photosensitive element 230, so as to protect the light receiving area of the photosensitive element 230 from being interfered by the solidified glue 230, and prevent the glue from occupying space between the photosensitive element 230 and the circuit board 250, thereby reducing the overall length of the camera module 200.

Further, in some embodiments, a counterbore 261 is formed at one end of the support base 260 where the zoom lens 100 is mounted, and the zoom lens 100 is mounted in the counterbore 261. Because the two ends of the supporting seat 260 are mutually light-transmitting, that is, the end of the supporting seat 260 where the zoom lens 100 is installed is provided with the through hole 262, and the end of the supporting seat 260 where the zoom lens 100 is installed is provided with the counter bore 261, the structures of the counter bore 261 and the through hole 262 are mutually overlapped, and the surface of the inner side of the end of the supporting seat 260 where the zoom lens 100 is installed forms a step-shaped structure, which can be used for erecting the zoom lens. Through the above design, on one hand, the stability of the connection between the zoom lens 100 and the support 260 is enhanced, and on the other hand, the overall length of the camera module 200 is reduced because the zoom lens 100 can be regarded as being embedded into the support 260.

Further, in some embodiments, the imaging assembly 210 further includes a voice coil motor 222, and the voice coil motor 222 is connected to the imaging lens 211 and drives the imaging lens 211 to move toward or away from the zoom lens 100. The voice coil motor 222 is a device that converts electric energy into mechanical energy and can realize linear and limited swing angle movements. The imaging lens 211 is connected to the voice coil motor 222, and under the driving of the voice coil motor 222, the imaging lens 211 moves toward a direction close to or away from the zoom lens 100 to achieve a zoom function, and the imaging module 200 can have a larger zoom range by matching with the zoom function of the zoom lens 100. In some embodiments, the voice coil motor 222 is connected to the circuit board 250, and the circuit board 250 can control the movement of the voice coil motor 222 with reference to the image data obtained from the photosensitive element 230 by the circuit board 250, so as to implement the auto zoom function.

In addition, referring to fig. 3 and fig. 4, it should be noted that in some embodiments, in other embodiments, the image module 200 can be applied to a periscopic image technology, in which the imaging component 210 includes a reflection prism 223 and at least one lens group 225 with refractive power, and the lens group 225 is located between the reflection prism 223 and the zoom lens 100. The lens group 225 is disposed coaxially with the zoom lens 100, and the reflection surface 224 of the reflection prism 223 is inclined to the optical axis of the lens group 225. The reflecting prism 223 is used for reflecting light, and the reflecting surface 224 of the reflecting prism 223 is inclined to the axis of the lens group 225, so that the propagation direction of the light can be changed, and the camera module 200 can realize a good zoom function with a smaller volume. For example, when the camera module 200 is used in a smart phone, a periscopic camera technology is adopted, so that the propagation direction of light can be changed, the optical axis of the imaging component 210 is intersected with the incident direction of the light entering the camera module 200, that is, the optical axis of the imaging component 210 is not in the thickness direction of the smart phone, and the smart phone can realize a good optical zoom function with a small volume.

It is understood that the number of the lens groups 225 in the imaging assembly 210 and the structural design of the lenses in the lens groups 225 determine the light adjusting capability of the imaging assembly 210, and the number of the lens groups 225 is not limited according to the requirements of the practical application scenario. Further, in some embodiments, two sets of coaxially disposed lens groups 225 are included in the imaging assembly 210, and the two sets of lens groups 225 are relatively movable. Thus, by changing the relative positions of the two groups of lenses 225, the focal length of the imaging unit 210 can be changed, and the imaging module 200 can have a wider zoom range in accordance with the zoom function of the zoom lens 100.

In addition, the zoom lens 100 can be disposed at other positions in the image pickup module. For example, in some embodiments, the zoom lens 100 is disposed on the object side of the imaging assembly 210; or the zoom lens 100 is disposed between the reflection prism 223 and the lens group 225; or the zoom lens 100 is disposed between two groups of lens groups 225. Of course, in other embodiments, the lens group 225 includes a plurality of lenses, and the zoom lens 100 is disposed between two of the lenses in the lens group 225.

Specifically, the electronic device 300 may be a periscopic camera. Of course, the electronic device 300 may also be applied to different fields according to different structural designs of the imaging component 210, for example, in other embodiments, the electronic device 300 may also be a device with a photographing function, such as a smart phone, a tablet computer, a car recorder, an aerial camera, a game console, and an AR/VR device. By adopting the zoom lens 100 in the electronic device 300, the electronic device 300 can have a light filtering function without additionally arranging a light filter, so that the space utilization rate of the electronic device 300 can be improved, and the size of the electronic device 300 can be reduced. In addition, the light-transmitting flexible element 130 is disposed in the electronic device 300, so that the electronic device 300 has a zoom function, and the focal length of the electronic device 300 can be increased, thereby improving the applicability of the electronic device 300.

Further, in some embodiments, the electronic device 300 may be disposed in an automobile (not shown), the automobile further includes a mounting member, the electronic device 300 is mounted on the mounting member, it is understood that the mounting member may be a rear-view mirror frame, a frame, and other parts of the automobile, and the electronic device 300 may be an onboard camera device such as a car recorder. Adopt electronic equipment 300 in the car, because electronic equipment 300 does not need additionally to set up the light filter and possesses the filtering function promptly, can promote the space utilization in electronic equipment 300, be favorable to reducing electronic equipment 300's size, and then reduce electronic equipment 300 occupation space in the car, promote the space utilization in the car.
