Referring to FIG. 3 , this application also provides a camera assembly 101 , which includes a lens module 10 and a photosensitive chip 20 . The lens module 10 is used to change the propagation path of light. The photosensitive chip 20 is used to receive light from the lens module 10 and convert the optical signal into an electrical signal. The lens module 10 and the photosensitive chip 20 may be arranged oppositely (as shown in FIG. 3 ), or may not be arranged oppositely. When arranged oppositely, the light emitted from the lens module 10 directly captures the photosensitive chip 20 . When they are not arranged oppositely, the light emitted from the lens module 10 can be reflected to the photosensitive chip 20 through the reflector.

Referring to FIG. 3 , the present application also provides a lens module 10 . The lens module 10 includes a lens barrel 12 and at least one lens 11 . The lens 11 is installed in the lens barrel 12 . The lens module 10 may further include at least one lens 13 , which is disposed in the lens barrel 12 and opposite to the lens 11 . The lens module 10 includes an object side and an image side. The object side refers to the side of the lens module 10 that is close to the photographed object. The so-called image side refers to the side of the lens module 10 that is far away from the photographed object. The lens 11 can be disposed on the object side, that is, the light first passes through the lens 11 and then reaches the lens 13 . The lens 11 may also be disposed between multiple lenses 13 . Of course, in other embodiments, the lens 11 can also be on the image side.

Referring to FIGS. 4 to 6 , this application also provides a lens 11 , which includes: a first light-transmitting layer 111 , a dielectric layer 112 and a first actuator 113 . Wherein, the first light-transmitting layer 111 can be elastically bent. The dielectric layer 112 is elastic and connected to one side of the first light-transmitting layer 111 . The first actuator 113 includes a first driving member 1131 and a second driving member 1132 . The first driving member 1131 is disposed on a side of the first light-transmitting layer 111 facing away from the dielectric layer 112 . The second driving member 1132 is disposed on a side of the first light-transmitting layer 111 away from the first driving member 1131 . The first driving member 1131 and/or the second driving member 1132 is used to drive the first light-transmitting layer 111 so that the first light-transmitting layer 111 elastically bends and passes through the first light-transmitting layer 111. The layer 111 drives the dielectric layer 112 to elastically deform. That is to say, any one of the first driving member 1131 and the second driving member 1132 can independently drive the first light-transmitting layer 111 to deform, or they can jointly drive the first light-transmitting layer 111 to deform. Layer 111 is deformed.

Wherein, the first light-transmitting layer 111 includes a first light-transmitting part 1111 and a first connecting part 1112. The first connecting portion 1112 is annular and is connected around the outer periphery of the first light-transmitting portion 1111 . The first light-transmitting part 1111 is connected to the dielectric layer 112 . The first connecting part 1112 is used to carry the first actuator 113 . The first light-transmitting layer 111 is in the shape of a film, has high light transmittance, and can be elastically bent within a certain range. The first light-transmitting layer 111 can also be called a flexible optical film. Optionally, the thickness of the first light-transmitting layer 111 is 20um-100um.

In one embodiment, the material of the first light-transmitting layer 111 may be glass, such as ultra-thin glass (UTG) with a thickness of 20 μm to 100 μm. The glass may be glass containing elements such as boron, phosphorus, and silicon, quartz glass, or glass containing elements such as sodium and potassium. In terms of preparation, the first light-transmitting layer 111 can be provided in the form of a circular glass wafer with a diameter of 50 mm to 300 mm. Then, the subsequent process of preparing the lens 11 (forming the first actuator 113) can be directly performed on the wafer. and finally slicing, thereby producing multiple lenses 11 at one time, which helps to improve preparation efficiency and mass production. Of course, in other embodiments, the first actuator 113 can be prepared first on glass with a conventional thickness of, for example, 150um, or 200um or above, and then the glass thickness can be ground thin to form a glass with a thickness of 20um to 100um. The first light-transmitting layer 111. In another embodiment, the first light-transmitting layer 111 can also be made of resin material, such as polymethyl methacrylate, polycarbonate, allyl diglycol dicarbonate, etc. In another embodiment, the first light-transmitting layer 111 may also be made of silicon dioxide. For example, a certain thickness of silicon dioxide is deposited on a silicon or glass substrate using a CVD method as the first light-transmitting layer 111 .

The dielectric layer 112 itself has elasticity and high light transmittance. Since the dielectric layer 112 is connected to the first light-transmitting layer 111, when the first light-transmitting layer 111 bends, the dielectric layer 112 will be driven by the first light-transmitting layer 111 and elastically deform accordingly. After the first light-transmitting layer 111 and the dielectric layer 112 are deformed, the light can be deflected, that is, the propagation direction of the light passing through the lens 11 will change. Therefore, the lens 11 can participate in the imaging process of the camera assembly 101 and is equivalent to a lens 13 . In addition, the degree of curvature of the first light-transmitting layer 111 can change as the driving force of the first actuator 113 changes, thereby making the focal length of the lens 11 adjustable. In Figure 5, the dashed lines represent light rays.

The dielectric layer 112 has a certain refractive index, such as 1.5. Optionally, the refractive index of the dielectric layer 112 is greater than the refractive index of the first light-transmitting layer 111 . The greater the refractive index of the dielectric layer 112, the stronger its ability to deflect light, and the lower the bending requirement for the first light-transmitting layer 111. That is, the first light-transmitting layer 111 can achieve the same effect by producing slight bending deformation. Focusing effect, it can be understood that this will be beneficial to extending the life of the first light-transmitting layer 111.

The dielectric layer 112 may be, but is not limited to, polydimethylsiloxane, polyurethane, fluorosilicone, etc. Aliphatic organic or inorganic acids can be added to the dielectric layer 112 as additives to improve stability and adjust the refractive index; in other embodiments, the dielectric layer 112 can also include titanium dioxide, zirconium oxide, tin oxide, zinc oxide, etc. for changing refractive index. The dielectric layer 112 can be prepared from completely liquid silicone oil, such as methyl silicone oil, phenyl silicone oil, hydroxyl silicone oil, etc., by adding a certain proportion of coupling agent to form a cured elastomer. The softness and hardness of the elastomer can be determined by the added coupling agent. Adjust the dosage ratio.

The first actuator 113 is used to drive the first light-transmitting layer 111 to elastically bend, and then drive the dielectric layer 112 to elastically deform through the first light-transmitting layer 111 . When the first actuator 113 stops working, both the first light-transmitting layer 111 and the dielectric layer 112 can return to their original state. In this application, the first actuator 113 includes a first driving member 1131 and a second driving member 1132. The first driving member 1131 and the second driving member 1132 are disposed on opposite sides of the first light-transmitting layer 111. A light-transmitting layer 111 can be bent under the joint action of the first driving member 1131 and the second driving member 1132 . The first driving member 1131 and the second driving member 1132 may be, but are not limited to, piezoelectric materials, voice coil motors, memory alloy motors, stepper motors, etc. The following content of this application only uses piezoelectric materials as examples.

It should be noted that although the first actuator 113 in the lens 11 provided by this application includes a first driving member 1131 and a second driving member 1132, during operation, the first driving member 1131 and the second driving member 1132 can work independently. That is to say, in one embodiment, the first driving member 1131 and the second driving member 1132 work simultaneously to jointly drive the first light-transmitting layer 111 to bend. In another embodiment, only one of the first driving member 1131 and the second driving member 1132 works and independently drives the first light-transmitting layer 111 to bend.

It should also be noted that when either one of the first driving member 1131 and the second driving member 1132 works independently, the first light-transmitting layer 111 can only protrude outward or recess inward, so that the lens 11 becomes Spherical mirror. When the first driving member 1131 and the second driving member 1132 operate simultaneously, the lens 11 may form a spherical mirror (as shown in FIG. 5 ) or an aspherical mirror (as shown in FIG. 6 ). The situation of spherical mirrors and aspherical mirrors will be introduced in detail in later embodiments.

In the related art, only one driving member is provided in the lens 11, and the bending degree of the first light-transmitting layer 111 is adjusted through the driving member, thereby achieving adjustable focal length. However, driving the first light-transmitting layer 111 to bend through a driving member can only make the first light-transmitting layer 111 protrude outward or recess inward. Correspondingly, the lens 11 can only form a spherical mirror. In addition, due to the limited driving force of one driving member, the bending amplitude range of the first light-transmitting layer 111 is small, so that the focal length variation range of the lens 11 is small.

Compared with related technologies, the first actuator 113 in the lens 11 provided by this application includes a first driving member 1131 and a second driving member 1132. The first driving member 1131 and the second driving member 1132 are disposed on the third Opposite sides of a light-transmitting layer 111 can cooperate with each other to jointly drive the first light-transmitting layer 111 to bend. Therefore, the lens 11 provided by the present application can not only form a spherical mirror that can be constructed in the related art, but also can form an aspherical mirror that cannot be constructed in the related art. Therefore, the lens 11 provided by the present application can be applied to more application imaging scenarios. In addition, when the first driving member 1131 and the second driving member 1132 jointly drive the first light-transmitting layer 111 to bend, compared with related technologies, the first light-transmitting layer 111 can obtain a larger bending amplitude, that is, , the form of joint driving can make the first light-transmitting layer 111 have a larger bending amplitude range. The larger bending amplitude means that the focal length of the lens 11 changes in a wider range, that is, the focal length can be adjusted in a wider range, and the light has better sensitivity. There are many different deflection effects, so it can be applied to more shooting scenes.

Optionally, please refer to Figures 5 and 6. The orthographic projections of the first driving member 1131 and the second driving member 1132 on the first light-transmitting layer 111 at least partially overlap. That is to say, the first The driving member 1131 and the second driving member 1132 are arranged oppositely, which is beneficial to the imaging of the camera assembly 101. It can be understood that if the above-mentioned orthographic projections do not overlap, the curved shape of the first light-transmitting layer 111 will be asymmetrical, resulting in uneven light distribution, resulting in low imaging quality. Further optionally, the orthographic projections of the first driving member 1131 and the second driving member 1132 on the gambler's light-transmitting layer are bent and coincident.

Optionally, please refer to FIG. 7 . The projections of the first driving member 1131 and the second driving member 1132 on the first light-transmitting layer 111 are both circular. Such an arrangement can make the circumferential deformation of the first light-transmitting layer 111 more uniform, which is beneficial to the focusing accuracy of the lens 11 . Further optionally, the first driving member 1131 and the second driving member 1132 are circular rings, so that the first light-transmitting layer 111 can be deformed uniformly around the circumference. Of course, in other embodiments, the shapes of the first driving member 1131 and the second driving member 1132 may also be rectangular rings, elliptical rings, etc.

Further, the first driving member 1131 and the second driving member 1132 are made of piezoelectric material. The piezoelectric material has the following characteristics: when the piezoelectric material is deformed by an external force in a certain direction, polarization will occur inside the material, and at the same time, positive and negative charges will appear on its two opposite surfaces. When the external force is removed, it will return to its uncharged state. On the contrary, when an electric field is applied in the polarization direction of the piezoelectric material, the piezoelectric material will deform. When the electric field is removed, the deformation of the piezoelectric material disappears. Therefore, when the first driving member 1131 and the second driving member 1132 are acted upon by an electric field, the first driving member 1131 and the second driving member 1132 will deform, thereby driving the first light-transmitting layer 111 bending. It can be understood that the deformation of the piezoelectric material itself is used to drive the bending of the first light-transmitting layer 111. The piezoelectric material only needs a simple structural form to achieve this, which is conducive to achieving a simplified and compact structure of the lens 11. change. Moreover, the production of the piezoelectric material itself is relatively simple, easy to make into the required shape, the cost is correspondingly low, and it is suitable for mass production.

The individual thicknesses of the first driving member 1131 and the second driving member 1132 may be 1um˜100um, such as 1um, 2um, 3um, 4um, 15um, etc. The piezoelectric material may be, but is not limited to, lead zirconate titanate (PZT).

In terms of preparation, in one embodiment, the piezoelectric material can be directly attached to the first light-transmitting layer 111 through a sol-gel method or a magnetron sputtering method, thereby obtaining the first driving member 1131 and the second Driver 1132. In another embodiment, the piezoelectric material can be prepared in advance into a block according to the required thickness and shape, and then bonded to the first light-transmitting layer 111 to obtain the first driving member 1131 and the second driving member 1131 . Item 1132. In yet another embodiment, a silk screen method can also be used to make the piezoelectric material into a slurry and then screen print it onto the film to obtain the first driving member 1131 and the second driving member 1132.

Several bending forms of the first light-transmitting layer 111 driven by the first actuator 113 will be introduced below with reference to the accompanying drawings.

Please refer to FIG. 8 , the first actuator 113 further includes a first electrode 1133 and a second electrode 1134 respectively connected to opposite sides of the first driving member 1131 . The first electrode 1133 and the second electrode 1134 are used to form an electric field that can cause the first driving member 1131 to deform. The first actuator 113 further includes a third electrode 1135 and a fourth electrode 1136 respectively connected to opposite sides of the second driving member 1132 . The third electrode 1135 and the fourth electrode 1136 are used to form an electric field that can cause the second driving member 1132 to deform. The material of each of the above electrodes may be, but is not limited to, a metal containing platinum (Pt). The electrode and driver can be bonded with transparent optical glue.

Please refer to Figures 9 and 10 in conjunction with Figure 8. In Figures 9 and 10, F1 represents tensile deformation, F2 represents compression deformation, and the corresponding arrow direction is the deformation direction. Taking the first driving member 1131 as an example (please refer to FIG. 7 ), when the first driving member 1131 undergoes tensile deformation, its inner diameter R1 becomes smaller and its outer diameter R2 becomes larger; when the first driving member 1131 compresses During deformation, its inner diameter R1 becomes larger and its outer diameter R2 becomes smaller. It should be noted that for subsequent drawings and descriptions involving F1 tensile deformation and F2 compression deformation, please refer to the description here. The first light-transmitting layer 111 has a first surface M1 facing away from the dielectric layer 112 . When the directions of the electric fields acted upon by the first driving member 1131 and the second driving member 1132 are opposite, the first surface M1 is deformed into a spherical surface. in. The spherical surface may be a concave spherical surface or a convex spherical surface. The spherical surface means that the curvature at the bend is consistent.
