Referring to fig. 1 to 4F of the drawings, an image capturing module according to a preferred embodiment of the present invention is disclosed and described in the following description, wherein the image capturing module includes a photosensitive member 10, a lens assembly 20, and a lens apparatus 30, and the photosensitive member 20 and the lens apparatus 30 are both held in a photosensitive path of the photosensitive member 10.

Specifically, the photosensitive assembly 10 includes a circuit board 11 and a photosensitive chip 12, and the photosensitive chip 12 is connected to the circuit board 11. Preferably, the photosensitive assembly 10 further includes a lens holder 13, the lens holder 13 is disposed on the circuit board 11, and the lens holder 13 at least surrounds the photosensitive area of the photosensitive chip 12, so that the photosensitive area of the photosensitive chip 12 can correspond to a light channel 131 defined by the lens holder 13, and thus, incident light can reach the photosensitive chip 12 after passing through the light channel 131 of the lens holder 13.

It should be noted that the manner in which the photosensitive chip 12 is connected to the circuit board 11 is not limited. For example, in this specific example of the camera module shown in fig. 1 to 4F, after the back surface of the photosensitive chip 12 is attached to the front surface of the wiring board 11, the pads of the photosensitive chip 12 and the pads of the wiring board 11 are connected by a connection line 14 to achieve connection of the photosensitive chip 12 and the wiring board 11.

It should be noted that the manner in which the lens base 13 is disposed on the circuit board 11 is not limited. For example, in this specific example of the camera module shown in fig. 1 to 4F, the lens mount 13 is integrally bonded to the wiring board 11 and a portion of the non-photosensitive region of the photosensitive chip 12 during molding, and the lens mount 13 forms the light passage 131 during molding to allow the photosensitive region of the photosensitive chip 12 to correspond to the light passage 131.

Optionally, the lens holder 13 is a prefabricated member, after the photosensitive chip 12 is attached to the circuit board 11, the lens holder 13 is attached to the circuit board 11 by an adhesive such as glue, and the photosensitive area of the photosensitive chip 12 corresponds to the light path 131 of the lens holder 13.

In addition, with continued reference to fig. 1, the photosensitive assembly 10 includes at least one electronic component 15, which may be, but is not limited to, a resistor, a capacitor, a processor, a driver, etc., wherein the electronic component 15 is mounted on the circuit board 11, and the electronic component 15 can be embedded by the lens holder 13.

In addition, with continued reference to fig. 1, the photosensitive assembly 10 further includes a filter 16, which may be, but is not limited to, an ir cut filter, wherein the filter 16 is attached to an inner side of the top surface of the lens base 13 to maintain the photosensitive path of the filter 16 on the photosensitive chip 12, so that the incident light can reach the photosensitive chip 12 through the light channel 131 of the lens base 13 after being filtered by the filter 16.

In this specific example of the camera module shown in fig. 1 to 4F, the lens assembly 20 is mounted on the outer side of the top surface of the lens holder 13 to maintain the photosensitive path of the photosensitive chip 12 of the photosensitive assembly 10, and the lens device 30 is integrated inside the lens assembly 20 to maintain the photosensitive path of the lens device 30 on the photosensitive chip 12 of the photosensitive assembly 10, so that incident light can reach the photosensitive chip 12 after passing through the lens assembly 20 and the lens device 30, respectively, to be photoelectrically converted by the photosensitive chip 12 for imaging.

It should be noted that the specific structure of the lens assembly 20 is not limited in the image capturing module of the present invention, for example, in this specific example of the image capturing module shown in fig. 1 to 4F, the lens assembly 20 includes a top lens 21 and a bottom lens 22, the top lens 21 includes a top lens barrel 211 and at least one top lens 212 assembled to the top lens barrel 211, the bottom lens 22 includes a bottom lens barrel 221 and at least one bottom lens 222 assembled to the bottom lens barrel 221, wherein the top lens barrel 211 of the top lens 21 and the bottom lens barrel 221 of the bottom lens 22 are respectively attached to opposite sides of the lens device 30 to integrate the lens device 30 inside the lens assembly 20, so that incident light can reach the chip 12 after passing through the top lens 21, the lens device 30 and the bottom lens 22, respectively, to be photoelectrically converted by the photo chip 12.

Specifically, with continued reference to fig. 1 to 4F, the lens apparatus 30 includes a zoom unit 31 and an anti-shake unit 32, the zoom unit 31 and the anti-shake unit 32 being disposed along a height direction (i.e., a Z direction), wherein the zoom unit 31 is configured to implement zooming of the camera module, and the anti-shake unit 32 is configured to implement anti-shake of the camera module.

It should be noted that the relative positions of the zoom unit 31 and the anti-shake unit 32 of the lens apparatus 30 are not limited in the image capturing module of the present invention. For example, in some embodiments of the camera module of the present invention, the zoom unit 31 is located at the object side of the anti-shake unit 32, that is, the incident light passes through the anti-shake unit 32 after passing through the zoom unit 31; in other embodiments of the camera module of the present invention, the zoom unit 31 is located at the image side of the anti-shake unit 32, i.e. the incident light passes through the zoom unit 31 after passing through the anti-shake unit 32.

With continued reference to fig. 2A-4F, the zoom unit 31 includes a light transmissive zoom substrate 311, a flexible and light transmissive zoom film 312, and a deformable zoom polymer 313, wherein the zoom polymer 313 is supported to the zoom substrate 311 to provide good support for the zoom polymer 313 by the zoom substrate 311 and define a planar shape of a first surface 3131 of the zoom polymer 313, wherein the zoom film 312 is supported to the zoom polymer 313 to define a planar shape of a second surface 3132 of the zoom polymer 313 by the zoom film 312, such that the zoom polymer 313 is held between the zoom substrate 311 and the zoom film 312. When a force is applied to the zoom film 312 to allow the zoom film 312 to bend toward a direction approaching the zoom base 311, the zoom film 312 can press the zoom polymer 313 toward the direction approaching the zoom base 311 to change the surface shape of the second surface 3132 of the zoom polymer 313 to change the optical power of the lens device 30, thereby achieving zooming of the image pickup module.

Preferably, the zoom film 312 and the second surface 3132 of the zoom polymer 313 are combined such that when a force is applied to the zoom film 312 to allow the zoom film 312 to bend away from the zoom substrate 311, the zoom film 312 can press the zoom polymer 313 away from the zoom substrate 311 to change the surface shape of the second surface 3132 of the zoom polymer 313 to change the optical power of the lens device 30, thereby achieving zooming of the camera module.

It should be noted that the material of the zoom substrate 311 is not limited in the image capturing module of the present invention, as long as it can provide good support for the zoom polymer 313 to define the surface shape of the first surface 3131 of the zoom polymer 313 and has high transmittance to visible light, for example, the zoom substrate 311 may be made of glass.

It should be noted that the material of the zoom film 312 is not limited in the image capturing module of the present invention, as long as it has good bending property to define the surface shape of the second surface 3132 of the zoom polymer 313 and has good light transmittance. For example, the zoom film 312 may be a flexible glass film such that the zoom film 312 is capable of changing and maintaining the shape of the second surface 3132 of the zoom polymer 313 when the zoom film 312 is forced to bend.

The deformable zoom polymer 313 is located between the zoom substrate 311 and the zoom film 312, the first surface 3131 of the zoom polymer 313 is attached to the zoom substrate 311 to define a plane shape of the first surface 3131 of the zoom polymer 313 by the zoom substrate 311, the second surface 3132 of the zoom polymer 313 is bonded to the zoom film 312 to define a plane shape of the second surface 3132 of the zoom polymer 313 by the zoom film 312, and the zoom polymer 313 has a relatively high elastic modulus and refractive index, which can generate converging or diverging effects on light rays in different shapes.

In this specific example of the lens device 30 shown in fig. 2A to 4F, in an initial state, the zoom polymer 313 has a flat cylindrical shape, and the central axis of the zoom polymer 313, the central axis of the zoom base 311, and the central axis of the zoom film 312 coincide to form the central axis of the zoom unit 31. When the zoom film 312 is bent toward the direction approaching the zoom base 311 by a force, the bent zoom film 312 can press the zoom polymer 313 toward the direction approaching the zoom base 311 to make the second surface 3132 of the zoom polymer 313 convex, so that the lens device 30 can collect light, and the magnitude of deformation of the second surface 3132 of the zoom polymer 313 increases in order from the central axis to the edge direction, that is, the magnitude of deformation of the edge portion of the zoom polymer 313 is greater than that of the central portion. Accordingly, when the zoom film 312 is bent in a direction away from the zoom base 311 by a force, the bent zoom film 312 can press the zoom polymer 313 in a direction away from the zoom base 311 to make the second surface 3132 of the zoom polymer 313 concave, so that the lens device 30 can radiate light, and the magnitude of deformation of the second surface 3132 of the zoom polymer 313 increases in order from the central axis to the edge direction, that is, the magnitude of deformation of the edge portion of the zoom polymer 313 is greater than that of the central portion.

Preferably, the diameter size of the zoom film 312 is larger than the diameter size of the zoom polymer 313, so that the zoom unit 31 forms a zoom avoiding space 314 between the zoom substrate 311 and the zoom film 312, and the zoom avoiding space 314 surrounds the zoom polymer 313, and when the zoom film 312 presses the zoom polymer 313 toward the zoom substrate 311, the zoom polymer 313 is pressed by the zoom film 312 to expand and deform toward the zoom avoiding space 314, so that the zoom polymer 313 has a degree of freedom of a more deformation amount, and in this way, the camera module can zoom within a larger range, so as to improve the imaging capability of the camera module.

And, when the zoom film 312 presses the zoom polymer 313 toward the direction approaching the zoom base 311, by allowing the zoom polymer 313 to expand and deform toward the zoom avoiding space 314, consistency of densities of a central portion and an edge portion of the zoom polymer 313 after deformation can be ensured, thereby facilitating control of optical power of the lens device 30 and further control of imaging quality of the image pickup module.

With continued reference to fig. 2A to 4F, the zoom unit 31 further includes a zoom base 315, the zoom base 315 having a through-hole-shaped zoom accommodation chamber 3151, wherein the zoom base 315 is fixedly connected to the zoom base 311, and the zoom polymer 313 is deformably held in the zoom accommodation chamber 3151 of the zoom base 315 to allow the zoom base 315 to surround the outside of the zoom polymer 313, such that the zoom base 315 can prevent the zoom polymer 313 from being exposed and prevent light from entering from the side of the zoom polymer 313.

Preferably, the zoom accommodation chamber 3151 of the zoom base 315 has a circular cross-sectional shape, the central axis of the zoom polymer 313 and the central axis of the zoom accommodation chamber 3151 of the zoom base 315 coincide, and the radius size of the zoom polymer 313 is smaller than the radius size of the zoom accommodation chamber 3151 of the zoom base 315, so that the zoom avoiding space 314 can be formed inside the zoom base 315 to allow the zoom polymer 313 to be expanded and deformed toward the direction of the zoom base 315 when being pressed by the zoom film 312.

It should be noted that the manner in which the zoom base 315 is fixedly connected to the zoom base 311 is not limited in the camera module of the present invention. For example, in some embodiments, the zoom base 315 may be attached to the zoom base 311 after being prefabricated to fixedly attach the zoom base 315 to the zoom base 311. In other embodiments, the zoom base 315 may be integrally formed on the zoom base 311, specifically, firstly, a glass material is selected as the zoom base 311, and secondly, the zoom base 315 is formed on an edge of the zoom base 311 by etching a silicon substrate, so as to fixedly connect the zoom base 315 to the zoom base 311, during which the zoom base 311 made of glass material is beneficial to ensure the flatness of the zoom base 315 and the reliability of the connection relationship between the zoom base 311 and the zoom base 315.

With continued reference to fig. 2A to 4F, the zoom unit 31 further includes a zoom driving part 316, the zoom driving part 316 includes a zoom piezoelectric element 3161 and has a zoom driving part through hole 3162, the zoom piezoelectric element 3161 is ring-shaped to form the zoom driving part through hole 3162 from the zoom piezoelectric element 3161, wherein an outer side of the zoom piezoelectric element 3161 is fixedly connected to the zoom base 315, and an inner side of the zoom piezoelectric element 3161 is fixedly connected to the zoom film 312, such that the zoom polymer 313 corresponds to the zoom driving part through hole 3162 of the zoom driving part 316 to avoid the zoom driving part 316 from shielding a light transmitting area of the lens device 30.

The upper side and the lower side of the zoom piezoelectric element 3161 have piezoelectric layers, respectively, and the piezoelectric layers of the zoom piezoelectric element 3161 are provided so as to be able to contract or expand in the width direction of the zoom piezoelectric element 3161.
