Referring to fig. 1 and 2, fig. 1 is a schematic cross-sectional view of an embodiment of a free-form surface lens according to the present application, and fig. 2 is a schematic overall structure of an embodiment of a camera according to the present application. The camera structure includes a free-form surface lens 100, a lens assembly 200, and a lens base 300.

With continued reference to FIG. 1, the free-form lens 100 includes a glass film layer 10 and a plurality of piezoelectric ceramic blocks 20. The glass film layer 10 includes a first surface 11 and a second surface 12 disposed opposite to each other, and a plurality of piezoelectric ceramic blocks 20 are disposed on one side of the second surface 12 in a circular arrangement.

Specifically, the glass film layer 10 has good flexibility. The piezoelectric ceramic block 20 deforms under the voltage excitation, and as the piezoelectric ceramic block 20 is fixedly connected with the second surface 12 of the glass film layer 10, the piezoelectric ceramic block 20 drives the glass film layer 10 to deform when deforming so as to change the curvature of the corresponding position of the glass film layer 10, thereby adjusting the light transmission effect. In addition, the piezoelectric ceramic blocks 20 are arranged in a circular ring shape, so that light is transmitted through the middle hollow area of the circular ring formed by the arrangement of the piezoelectric ceramic blocks, and the light transmission effect of the camera is prevented from being influenced.

In one embodiment, referring to fig. 3 in conjunction with fig. 1, fig. 3 is a bottom view of one embodiment of the freeform lens of the present application. The piezoelectric ceramic block 20 comprises a third surface 21 and a fourth surface 22 which are arranged opposite to each other, the third surface 21 of the piezoelectric ceramic block 20 is connected with the second surface 12 of the glass film layer 10, and the fourth surface 22 is provided with a plurality of first contacts 23.

Specifically, the piezoelectric ceramic block 20 can receive a voltage excitation signal through the corresponding first contact 23 to generate corresponding deformation, and simultaneously drive the glass film layer 10 to generate deformation, so as to eliminate distortion generated in the photographing process. When the piezoelectric ceramic blocks 20 are arranged on the second surface 12 side of the glass film layer 10, gaps are formed between the adjacent piezoelectric ceramic blocks 20, so that interference of the piezoelectric ceramic blocks 20 during deformation is avoided, and overall stability of the camera is improved. The specific size of the gap between the adjacent piezoelectric ceramic blocks 20 can be set according to actual requirements.

Alternatively, the piezoelectric ceramic blocks 20 are connected with the glass film layer 10 by coating glue on the plurality of piezoelectric ceramic blocks 20. Alternatively, the piezoelectric ceramic block 20 is connected to the glass film layer 10 by a lamination process.

In addition, fig. 3 only schematically illustrates that 8 piezoelectric ceramic blocks 20 are disposed on one side of the second surface 12, but in practical applications, the number of piezoelectric ceramic blocks 20 included in the camera structure of the present application may be other, for example, 6, 7, 9, or 10. The larger the number of the piezoelectric ceramic blocks 20, the smaller the volume of each piezoelectric ceramic block 20, and the higher the adjustment accuracy of the free-form surface lens 100, and the higher the manufacturing cost.

In an implementation scenario, please refer to fig. 4 in conjunction with fig. 3, fig. 4 is a top view of an embodiment of a fourth surface of the piezoelectric ceramic of the present application. The fourth surface 22 of each piezoceramic block 20 is provided with a plurality of first contacts 23. The fourth surface 22 is in a fan ring shape, and includes a first arc edge 221, a second arc edge 222, a first side edge 223 and a second side edge 224, where the length of the first arc edge 221 is greater than that of the second arc edge 222, and two first contacts 23 on the same piezoelectric ceramic block 20 are respectively close to a first connection position between the first arc edge 221 and the first side edge 223 or a second connection position between the first arc edge 221 and the second side edge 224. It should be noted that, in this embodiment, the fourth surface 22 of each piezoelectric ceramic block 20 is provided with two first contacts 23, and in practical application, the number of the first contacts 23 may be other, such as 1 or 3.

Specifically, in order to form a circular ring after the piezoelectric ceramic blocks 20 are arranged, the cross sections of the piezoelectric ceramic blocks 20 are arranged as a fan ring, that is, the fourth surface 22 includes a first arc edge 221 and a second arc edge 222 which are oppositely arranged, and a first side edge 223 and a second side edge 224 which are correspondingly arranged. By arranging the two first contacts 23 on the same piezoelectric ceramic block 20 in a graphical manner, so that the distance between the two first contacts 23 is larger, when corresponding voltage excitation signals are received, the transmission range of the voltage excitation signals on the piezoelectric ceramic block 20 is larger, and therefore the piezoelectric ceramic block 20 can generate larger deformation amount so as to adapt to the deformation requirements in more scenes. In addition, by disposing two first contacts 23 on the same piezoelectric ceramic block 20 on the side close to the first arc edge 221, the manufacturing difficulty and the manufacturing cost of the first contacts 23 are reduced.

Alternatively, in other implementation scenarios, the arrangement manner of the first contacts 23 on the same piezoelectric ceramic block 20 may be other, for example, one first contact 23 is disposed at the connection between the first arc edge 221 and the first side edge 223, and another first contact 23 is disposed at the connection between the second arc edge 222 and the second side edge 224; alternatively, one first contact 23 is disposed at a junction of the first arc edge 221 and the second side edge 224, and the other first contact 23 is disposed at a junction of the second arc edge 222 and the first side edge 223.

On the premise of not influencing light transmission, by applying corresponding voltage excitation signals to at least part of the piezoelectric ceramic blocks 20, the glass film layer 10 is driven to generate corresponding deformation, so that the imaging process of the camera is corrected, distortion in a shot picture is avoided, and the quality of the shot image is improved.

Wherein the first flexible circuit board 30 may be connected to the piezoelectric ceramic block 20 by a bonding process, and the first contact 23 is electrically connected to the corresponding second contact 32.

In an implementation scenario, please continue to refer to fig. 5, in order to prevent the first flexible circuit board 30 from affecting the light transmittance of the camera, a first through hole 33 is disposed on the connection surface 31 of the first flexible circuit board 30. The first through hole 33 is matched with a middle area formed by surrounding the piezoelectric ceramic blocks 20.

Specifically, in response to the plurality of piezoelectric ceramic blocks 20 being arranged in a circular ring shape, that is, the middle area formed by surrounding the plurality of piezoelectric ceramic blocks 20 is circular, the first through hole 33 is also circular, and the diameter of the first through hole 33 is the same as the diameter of the inner circle of the circular ring formed by the plurality of piezoelectric ceramic blocks 20, so as to prevent the first through hole 33 from affecting the light transmission effect of the camera.

Alternatively, in other implementation scenarios, the diameter of the first through hole 33 may be slightly larger than the diameter of the inner circle of the ring formed by the plurality of piezoelectric ceramic blocks 20 without affecting the arrangement of the second contact 32, so as to reduce the manufacturing cost of the first flexible circuit board 30.

In another embodiment, referring to fig. 2, to control the plurality of piezoelectric ceramic blocks 20, the camera structure further includes a second flexible circuit board 40 and a controller (not shown).

Specifically, the second flexible circuit board 40 is located at a side of the lens base 300 away from the lens assembly 200, and is electrically connected with the first flexible circuit board 30.

Specifically, after the piezoelectric ceramic driving module generates a voltage excitation signal, the voltage excitation signal is sequentially transmitted to the corresponding piezoelectric ceramic block 20 through the second flexible circuit board 40, the first flexible circuit board 30, the second contact 32 and the first contact 23, so that the piezoelectric ceramic block 20 is correspondingly deformed. It should be noted that, the voltage excitation signal is generated for each piezoelectric ceramic block 20, that is, the voltage excitation signals received by different piezoelectric ceramic blocks 20 may be different, and the deformations generated by the corresponding piezoelectric ceramic blocks 20 may be different in response to the received voltage excitation signals.

The material of the supporting layer 70 may be silica gel or the like.

The casing 80 is located at the periphery of the free-form surface lens 100, and is used for fixing and protecting the free-form surface lens 100, i.e. the outer glass 60, the glass film layer 10, the piezoelectric ceramic block 20 and the first flexible circuit board 30.

In addition, the housing 80 may also be used for the connection between the freeform lens 100 and the lens assembly 200. For example, the first end 201 of the lens assembly 200 is threadably coupled to an end of the housing 80 remote from the outer glass 60; alternatively, the first end 201 of the lens assembly 200 is fixedly coupled to the housing 80 by applying glue.

In response to the distortion in the image signal, the piezoceramic drive module determines the piezoceramic blocks 20 that need to be adjusted according to the specific location of the distortion and generates a corresponding voltage excitation signal. The piezoelectric ceramic driving module transmits the generated voltage excitation signal to the piezoelectric ceramic block 20 corresponding to the distortion position through the second flexible circuit board 40, the first flexible circuit board 30, the second contact 32 and the first contact 23 in sequence, so that the piezoelectric ceramic block 20 extends or contracts in the horizontal direction and/or the vertical direction, and the curvature of the corresponding position of the glass film layer 10 is adjusted, so that the distortion generated in the shooting process is eliminated.

In addition, the piezoelectric ceramic driving module in the processor can control the camera to realize automatic focusing by simultaneously controlling all piezoelectric ceramic blocks 20 to generate the same deformation.
