Referring to fig. 2, a lens barrel 10 according to an embodiment of the present disclosure includes a first lens 12, a plurality of second lenses 13, and a first iris 14. The first lens 12 and the plurality of second lenses 13 are sequentially arranged in the lens barrel 11 of the lens 10 along the optical axis direction of the lens 10, and at least one second lens 13 is a liquid lens 131. The variable aperture stop 14 is provided in a stack with the first lens 12 and the second lens 13, the first variable aperture stop 14 is used to change the light output amount of the lens 10, and the liquid lens 131 is used to change the focal length of the lens 10.

The lens 10, the first iris diaphragm 14 and the liquid lens 131 can change the aperture size and the focal length of the lens 10, so that the lens 10 can meet different shooting requirements, and user experience is improved.

The liquid lens 131 is a variable focus optical lens that utilizes the principle of electrowetting on dielectric (EWOD). It can change the shape of the drop by an applied voltage, and thus its focal length. Therefore, the liquid lens 131 can change the focal length of the lens 10, convenience and rapidness are achieved, and user experience is improved.

The lens barrel 10 may be made of plastic. The ductility of the plastic is good, which is beneficial to the manufacture of the lens barrel 10 and improves the mass production of the lens barrel 10. Of course, the lens barrel 10 may be made of not only plastic. The material of the lens barrel 10 may be set according to circumstances. For example, in other embodiments, the lens barrel 10 may be made of a metal material such as iron or an alloy. The specific material of the lens barrel 10 is not limited herein.

In some embodiments, the first iris 14 comprises an electrochromic iris.

The simple structure of electrochromic iris diaphragm, be favorable to the miniaturized production of first iris diaphragm 14, and then be favorable to the miniaturized design of camera lens 10 to electrochromic iris diaphragm operation is more convenient, is favorable to promoting first iris diaphragm 14's the ability of controlling, promotes user experience.

Referring to fig. 3, in one example, the electrochromic iris diaphragm includes a first transparent substrate 141, a first transparent electrode 142, an electrochromic layer 143, a second transparent electrode 145, and a second transparent substrate 144, which are sequentially stacked. Wherein, connect through connecting layer 146 between first transparent electrode 142 and the second transparent electrode 145, electrochromic layer 143 is wrapped up by connecting layer 146, so be favorable to promoting electrochromic layer 143's stability.

In the description of the present application, the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Further, the electrochromic layer 143 includes an electrochromic material, and optical properties (reflectivity, transmittance, absorption, etc.) of the electrochromic material can undergo a stable and reversible color change under the action of an applied electric field, so that the electrochromic material exhibits a reversible change in color and transparency in appearance. With this arrangement, the amount of incident light to the second lens 13 can be changed by energizing the first transparent electrode 142 and the second transparent electrode 145 to change the optical properties of the electrochromic layer 143, thereby controlling the transmittance of light at the electrochromic iris.

For example, in the case where the electrochromic iris diaphragm is powered off, the electrochromic layer 143 is colored, and at this time, the transmittance of light at the electrochromic layer 143 is small. When the electrochromic iris circuit is turned on, the electrochromic layer 143 is switched to a transparent state, and at this time, the transmittance of light at the electrochromic layer 143 is large.

As shown in fig. 4 and 5, the electrochromic iris in fig. 4 is in the energized state, and the electrochromic iris is in the colored state and is in the transparent state, so that light entering the electrochromic iris will not be absorbed by or reflected at the electrochromic iris but will pass through the electrochromic iris. The electrochromic iris in fig. 5 is in the de-energized state, in which the electrochromic iris is in the colored state, so that light entering the electrochromic iris is either absorbed by the electrochromic iris or reflected at the electrochromic iris and does not pass through the electrochromic iris.

Here, the intensity of transparency of the color of the electrochromic layer 143 may be proportional to the magnitude of the current passing through the electrochromic iris, that is, the light transmittance of the electrochromic layer 143 gradually increases as the current passing through the electrochromic iris is larger, and the light transmittance of the electrochromic layer 143 gradually decreases as the current passing through the electrochromic iris is smaller. This is advantageous for controlling the light transmittance of the electrochromic iris, and thus, varying the amount of incident light into the second lens 13 is achieved.

In the above example, the electrochromic iris in fig. 5 is in the off state, in which the current through the electrochromic iris is 0 and the transmittance of the electrochromic iris in fig. 5 is the minimum value. The electrochromic iris in fig. 4 is in the energized state, and at this time, the current passing through the electrochromic iris is set to the maximum value, and the transmittance of the electrochromic iris in fig. 4 is also set to the maximum value.

Further, the material of the first transparent substrate 141 includes blue glass. The main component of the blue glass is phosphate or fluorophosphate, which has high absorptivity to infrared light, and the first transparent substrate 141 made of the blue glass has good filtering effect on infrared light, thereby being beneficial to improving the shooting quality. The material of the second transparent substrate 144 may be the same as or different from the material of the first transparent substrate 141. For example, the second transparent substrate 144 may be made of blue glass or optical glass. The second transparent substrate 144 may also be made of PET (Polyethylene terephthalate), which has high film forming property, optical property and weather resistance, and the second transparent substrate 144 made of PET has good light transmittance. The second transparent substrate 144 may be made of a material with good light transmittance, such as PI (Polyimide).

In one example, the connecting layer 146 may be made of an adhesive. Due to the arrangement, the connection between the first transparent electrode 142 and the second transparent electrode 145 is facilitated, and the light transmittance of the adhesive is low, so that the electrochromic layer 143 can be well shielded from light and prevented from light leakage. Of course, the connecting layer 146 can be made of glue. The specific material of the connection layer 146 may be set according to different situations. The specific material of the connection layer 146 is not limited herein.

In some embodiments, the number of the second lenses 13 is at least two, the number of the liquid lenses 131 is at least one, and the liquid lenses 131 are arranged in parallel with the second lenses 13.

The mutual matching of the second lenses 13 and the liquid lenses 131 changes the focal length of the lens 10, so that the lens 10 can meet different shooting requirements, and the user experience is improved.

In the present embodiment, the number of the second lenses 13 is three, and the number of the liquid lenses 131 is one, and there are many cases where the positional relationship between the liquid lenses 131 and the other two second lenses 13 is established.

Referring to fig. 2, for example, in one example, the liquid lens 131 is located between two other second lenses 13.

Referring to fig. 6, for another example, in another example, the liquid lens 131 and the two other second lenses 13 are sequentially arranged along the optical axis direction of the lens barrel 10, and the liquid lens 131 is disposed close to the first lens 12.

Referring to fig. 7, for example, in another example, another two second lenses 13 and the liquid lens 131 are sequentially arranged along the optical axis direction of the lens 10, and the liquid lens 131 is disposed away from the first lens 12.

Of course, as can be seen from the above description, the number of the second lenses 13 is not only three, but also the number of the liquid lenses 131 is not only one, and the specific numbers of the second lenses 13 and the liquid lenses 131 can be set according to different situations.

For example, in the other embodiments, the number of the second lenses 13 is two, and the number of the liquid lenses 131 is one, and in this case, the positional relationship between the liquid lenses 131 and the other second lens 13 is as follows.

Referring to fig. 8, in one example, the liquid lens 131 and the second lens 13 are sequentially arranged along the optical axis of the lens 10, and the liquid lens 131 is disposed close to the first lens 12.

Referring to fig. 9, in another example, another second lens 131 is sequentially arranged along the optical axis of the lens 10, and the second lens 131 is disposed away from the first lens 12.

For example, in another embodiment, the number of the second lenses 13 is three, and the number of the liquid lenses 131 is two, and in this case, the positional relationship between the two liquid lenses 131 and the other second lens 13 is as follows.

Referring to fig. 10, in one example, another second lens 13 is located between two liquid lenses 131.

Referring to fig. 11, in another example, another second lens 13 and two liquid lenses 131 are sequentially arranged along the optical axis direction of the lens barrel 10, and the another second lens 13 is disposed close to the first lens 12.

Referring to fig. 12, in another example, two liquid lenses 131 and another second lens 13 are sequentially arranged along the optical axis direction of the lens barrel 10, and the two liquid lenses 131 and the another second lens 13 are located at two sides of the first lens 12.

As can be seen from the above, the number of the second lenses 13 and the number of the liquid lenses 131 can be set according to different situations, and the positional relationship between the liquid lenses 131 and the other several second lenses 13 can also be set according to different situations, and the specific number and the specific positional relationship between the second lenses 13 and the liquid lenses 131 are not limited herein.

Referring to fig. 9 and 15, in some embodiments, the liquid lens 131 includes a body 1311 and at least one optical wall 13111 connected to the body 1311, the body 1311 and the optical wall 13111 enclose a cavity 13112, and a transparent liquid is stored in the cavity 13112, and is used for changing the focal length of the lens 10 when the shape of the transparent liquid is changed.

The transparent liquid has conductivity, and the shape of the liquid drop of the transparent liquid changes after the transparent liquid is electrified, so that the function of zooming the liquid lens 131 is realized.

Wherein, the light-transmitting liquid can be an ionic solution. For example, the light-transmissive liquid is a potassium sulfate solution. Of course, the transparent liquid can be not only potassium sulfate solution, but also specific types of the transparent liquid can be set according to different situations. The specific type of light-transmissive liquid is not limited herein.

In one example, the inner walls of the body 1311 and the optical walls 13111 are hydrophobic treated so that the light-transmissive liquid does not stick to the inner walls of the body 1311, facilitating the collection of the light-transmissive liquid within the body 1311.

Further, the arrangement of the optical wall 13111 facilitates adjustment of the light-exiting angle of the light, and the optical wall 13111 facilitates design of the optical system and optimization of optical phase difference compared to a plane.

The optical wall 13111 may be a spherical surface, an aspherical surface, a concave surface, or another type of arc surface, and the specific type of the optical wall 13111 may be set according to different situations.

Referring to fig. 9 and 15, in one example, the body 1311 is formed with a through hole 13113 in communication with the cavity 13112, and the through hole 13113 is used to control the amount of the light-transmissive liquid in the cavity 13112 to change the curvature of the optical wall 13111.

In the above example, the optical wall 13111 is made of a flexible material (flexible plastic). The transparent liquid can be filled into the cavity 13112 through the through hole 13113, and since the optical wall 13111 is made of flexible material, when the liquid in the cavity 13112 is too much, the optical wall 13111 will bulge outwards, thereby changing the curvature of the optical wall 13111.

That is, the liquid lens 131 can change the focal length of the lens 10 by electrically changing the shape of the liquid drop of the transparent liquid, and can also change the curvature of the optical wall 13111 by changing the amount of the transparent liquid in the cavity 13112.

Of course, the specific manner of changing the focal length of the lens 10 by using the liquid lens 131 to pass light is not limited to the above two, and may be specifically set according to actual situations, and only needs to enable the liquid lens 131 to change the focal length of the lens 10, which is not limited herein.

In the example of fig. 15, the number of optical walls 13111 is two and is connected to the body 1311, wherein the body 1311 may be made of a light-impermeable material, for example, black plastic. Of course, the body 1311 may be made of not only black plastic. The specific material of the body 1311 may be set according to different situations, and the specific material of the body 1311 is not limited herein.

In the present embodiment, the number of the optical walls 13111 is two, and two optical walls 13111 are provided oppositely on the liquid lens 131, wherein, as shown in fig. 9, in such an example, the two optical walls 13111 are circular arc surfaces and are recessed inward. As shown in fig. 13, in such an example, the two optical walls 13111 are circular arc surfaces and are convex outward. As shown in fig. 14, in such an example, the two optical walls 13111 are circular arc surfaces and one of the circular arc surfaces is convex outward and the other circular arc surface is concave inward. Of course, the optical wall 13111 may not be limited to the above-mentioned cases, and may be designed according to different situations, for example, in other embodiments, the optical wall 13111 may also be a wave-shaped arc surface. The specific type of optical wall 13111 is not limited in this regard.

Referring to fig. 11, the first variable aperture stop 14 is disposed between the first lens 12 and the second lens 13. With this arrangement, the light output amount of the light beam emitted from the first lens 12 can be changed, and the light input amount through the second lens 13 can be changed, thereby changing the light output amount of the lens 10.

Referring to fig. 12, the first iris diaphragm 14 is sandwiched between two second lenses 13. With this arrangement, the light output amount through the second lens 13 can be changed, thereby changing the light output amount of the lens 10.

Referring to fig. 13, the first iris 14 is disposed on the object side of the first lens element 12. This arrangement can change the amount of light entering the first lens 12 after passing through the first iris diaphragm 14, thereby changing the amount of light exiting the lens 10.

Referring to fig. 14, the first variable aperture stop 14 is disposed on an image side of the second lens element 13 of the at least one second lens element 13, which is far from the first lens element 12. With this arrangement, the light output amount of the lens 10 is changed by the light output amount of the light ray that is emitted from the image side of the second lens 13 and passes through the first variable aperture 14.

Of course, the position of the first iris diaphragm 14 is not just the above-mentioned ones. The specific position of the first iris diaphragm 14 may be set according to different situations. The specific position of the first iris diaphragm 14 is not limited herein.

Further, in a case where the first iris diaphragm 14 is disposed between the first lens 12 and the second lens 13, the first iris diaphragm 14 is disposed on the first lens 12.

The first iris diaphragm may be attached to the first lens 12, and the first iris diaphragm 14 may be attached to the first lens 12 by light-transmitting adhesive. The first iris diaphragm 14 may be screwed with the first lens 12 by a light-passing screw. It is not limited to how the first iris diaphragm 14 is attached to the first lens 12.

According to the camera 100 of the embodiment of the application, the first iris diaphragm 14 and the liquid lens 131 are arranged to change the size of the iris diaphragm and the focal length of the lens 10, so that the lens 10 can meet different shooting requirements, and the user experience is improved.

In the present embodiment, the lens 10 is disposed on the side of the image sensor 103, and more specifically, the lens 10 is disposed between the image sensor 103 and the periscopic lens 102.

The provision of the housing 101 can protect the periscopic lens 102, the lens 10, and the image sensor 103 within the housing 101. Therefore, external water vapor or an ash layer is prevented from being attached to the periscopic lens 102, the lens 10 and the image sensor 103, the periscopic lens 102, the lens 10 and the image sensor 103 are prevented from being damaged due to the fact that the external water vapor or the ash layer is attached to the periscopic lens 102, the lens 10 and the image sensor 103, and the service life of the camera 100 is prolonged.

Further, the housing 101 may be made of plastic. The ductility of the plastic is high, which is advantageous for molding the housing 101 and for mass production of the housing 101. Of course, the housing 101 may be made of more than plastic. The specific material of the housing 101 may be set according to different situations. For example, in other embodiments, the housing 101 may be made of a metal material such as stainless steel or alloy. The specific material of the housing 101 is not limited herein.

Wherein the housing 101 may include a first housing 1011 and a second housing 1012, the periscopic lens 102 is disposed in the first housing 1011, and the lens 10 and the image sensor 103 are disposed in the second housing 1012, in one example, the first housing 1011 and the second housing 1012 may be integrally formed, and in another example, the first housing 1011 and the second housing 1012 may be separately formed. That is, the first shell 1011 and the second shell 1012 can be spliced into the housing 101 by clipping, bonding or screwing. Alternatively, the first shell 1011 and the second shell 1012 are integrally formed.
