In combination with <FIG> and <FIG>, the imaging module <NUM> includes a substrate <NUM>, a sensor assembly <NUM>, a lens assembly <NUM>, and an adjustable lens assembly <NUM>. The sensor assembly <NUM> is arranged on the substrate <NUM> and configured to receive light passing through the adjustable lens assembly <NUM> and the lens assembly <NUM>. The adjustable lens assembly <NUM> includes a piezoelectric actuator <NUM> and an adjustable lens <NUM> (as illustrated in <FIG>). The piezoelectric actuator <NUM> is configured to drive the adjustable lens <NUM> to deform under the action of an electrical signal, so as to change a focal length of the imaging module <NUM>.

In some embodiments of the present disclosure, the substrate <NUM> may include a wiring board and electronic components arranged on the wiring board.

The electronic components may be transistors, capacitors, inductors, etc. The substrate <NUM> may be used to connect the imaging module <NUM> to a motherboard of the electronic apparatus <NUM>, for example to electrically connect the sensor assembly <NUM> and the adjustable lens assembly <NUM> to the motherboard, so as to enable the imaging module <NUM> to communicate with the motherboard of the electronic apparatus <NUM>.

As illustrated in <FIG>, the sensor assembly <NUM> is arranged on the substrate <NUM>. The sensor assembly <NUM> may be configured to convert a received optical signal into an electrical signal, and transmit the electrical signal through the substrate <NUM> to a processor of the electronic apparatus <NUM>, for a final imaging. The sensor assembly <NUM> includes a sensor <NUM> and a package body <NUM>. The sensor <NUM> is configured to receive the light, and the sensor <NUM> may be a CCD or CMOS image sensor. The package body <NUM> is configured to package the sensor <NUM>. In the embodiment of the present disclosure, the sensor <NUM> may be fixed to the package body <NUM>, and the package body <NUM> may be fixed with the substrate <NUM> by means of an adhesive or the like. Furthermore, the package body <NUM> may also carry an optical filter <NUM> thereon, and the optical filter <NUM> may be configured to filter an interference light entering the imaging module <NUM>, for example. When the imaging module <NUM> is a visible light imaging module, the optical filter <NUM> may be configured to filter an infrared light, and in this case, the optical filter <NUM> may, in particular, be a blue glass to reduce the influence of the infrared light on the imaging quality. When the imaging module <NUM> is an infrared imaging module <NUM>, the optical filter <NUM> may be configured to filter a visible light to reduce the influence of the visible light on the imaging quality.

Continuing to refer to <FIG>, the lens assembly <NUM> may be arranged on the sensor assembly <NUM>. In particular, the lens assembly <NUM> includes a lens barrel <NUM>, which may be carried on the package body <NUM>, and a lens <NUM>, which may be received in the lens barrel <NUM>. The entire lens barrel <NUM> may have a small upper portion and a large lower portion so that the lens barrel <NUM> may be stable after being mounted. The lens barrel <NUM> includes a top face <NUM> and a bottom face <NUM> facing away from each other, the bottom face <NUM> may be connected with the package body <NUM>, and the top face <NUM> may be connected with the adjustable lens assembly <NUM>. A plurality of the lenses <NUM> may be provided, and the lenses <NUM> may change a light path of the light entering the imaging module <NUM> to have a converging or diverging influence on the light. In the embodiment of the present disclosure, the focal length of the lens assembly <NUM> is not adjustable, i.e., the distance among the plurality of lenses <NUM> will not need to be adjusted, so that an additional driving apparatus (such as a voice coil motor) may be not needed to drive the lenses <NUM> to move, and thus the lens assembly <NUM> is simple in structure and small in size.

As illustrated in <FIG> and <FIG>, the adjustable lens assembly <NUM> is arranged on the lens assembly <NUM>, and the light sequentially passes through the adjustable lens assembly <NUM> and the lens assembly <NUM> to enter the imaging module <NUM>. In some embodiments of the present disclosure, the adjustable lens assembly <NUM> is arranged on the top face <NUM> of the lens barrel <NUM>, and the lens assembly <NUM> is arranged between the substrate <NUM> and the adjustable lens assembly <NUM>, so that the adjustable lens assembly <NUM> is easy to disassemble and replace. The adjustable lens assembly <NUM> includes a piezoelectric actuator <NUM> and an adjustable lens <NUM>.

The piezoelectric actuator <NUM> may be electrically connected to the substrate <NUM>, may be made of a material with a piezoelectric effect, such as a piezoelectric ceramic, and may deform under the action of an electrical signal, such as a voltage. The adjustable lens <NUM> may be made of a transparent flexible polymer, and tends to deform under a squeezing or pulling action of an external force so as to change a curvature of an outer surface of the adjustable lens <NUM>, thereby changing a refraction action of the adjustable lens <NUM> on the light, i.e. changing a focal length of the imaging module <NUM>.

Since there is no need to drive the entire lens <NUM> to move to change the focal length, the use of the adjustable lens assembly <NUM> has the following advantages: (<NUM>) the power consumption of the adjustable lens assembly <NUM> is low when changing the focal length, for example, the power consumption of only <NUM> milliwatts may be required; (<NUM>) the adjustable lens assembly <NUM> does not have the problem that the difficulty of driving the lens <NUM> to move is different due to the different arrangement directions of the imaging module <NUM>, that is, changing the focal length is not affected by gravity; (<NUM>) the plurality of lenses <NUM> do not need to move relative to one another, and thus there is not the problem of instability of an optical axis when the relative movement of the plurality of lenses <NUM> shifts; (<NUM>) when the adjustable lens assembly <NUM> is to be tested and corrected, only one adjustable lens <NUM> needs to be tested and corrected, and the plurality of lenses <NUM> do not need to be tested and corrected, which reduces the cost of the test and correction; (<NUM>) the adjustable lens <NUM> does not have hysteresis under the action of the electrical signal.

When the focal length of the imaging module <NUM> needs to be adjusted, the electrical signal of a corresponding size is applied to the piezoelectric actuator <NUM> according to a size of the focal length required to be adjusted, so that the piezoelectric actuator <NUM> generates a corresponding deformation, the deformation of the piezoelectric actuator <NUM> causes the adjustable lens <NUM> to be affected by an external force, and thus the adjustable lens <NUM> generates a corresponding deformation, thereby finally achieving the purpose of adjusting the focal length. It will be appreciated that since a conventional mechanical structure is not required for driving during the entire process of adjusting the focal length, the adjustable lens assembly <NUM> does not generate a noise during operations, and the time required for adjusting the focal length is short, which can achieve a rapid focusing.

In addition, in the process of realizing zooming by using the adjustable lens assembly <NUM>, the distance between the adjustable lens <NUM> and the sensor <NUM> is not changed, and a field of view range of the imaging module <NUM> is not changed, such that a plurality of images at different object-side focal planes can be shot in a short time in combination with the fast focusing feature of the adjustable lens assembly <NUM>. Synthesizing the plurality of images can obtain an image with all objects in the field of view being clear. Or, a plane or a depth range required to be imaged clearly is selected from the plurality of images, and then a background is blurred to achieve a background blurring by using a single imaging module <NUM>.

In the related art, the volume of the lens module is greatly increased due to the existence of the voice coil motor, and thus the lens module is prevented from being made smaller and thinner. Moreover, the voice coil motor drives the lens to move under the action of a magnetic force so as to complete focusing, and hence peripheral magnetic fields generated by other electronic components can interfere with the normal operation of the voice coil motor. In summary, in the electronic apparatus <NUM> according to the embodiment of the present disclosure, the electrical signal can act on the piezoelectric actuator <NUM> to drive the adjustable lens <NUM> to deform so as to change the focal length of the imaging module <NUM>, and the additional driving apparatus such as the voice coil motor can be omitted so as to reduce the size of the imaging module <NUM>. Moreover, the peripheral magnetic fields generated by other electronic components will not affect the operation of the adjustable lens assembly, and hence the imaging module has a strong anti-interference capability.

As illustrated in <FIG> and <FIG>, in some embodiments, the adjustable lens assembly <NUM> further includes at least two contact terminals <NUM>. The contact terminals <NUM> are connected to the piezoelectric actuator <NUM>. A plurality of conductive members <NUM> are arranged to the lens barrel <NUM>, and both ends of at least two of the plurality of conductive members <NUM> are electrically connected to the contact terminal <NUM> and the substrate <NUM>, respectively, so as to transmit the electrical signal.

In the embodiment of the present disclosure, two contact terminals <NUM> are provided, and both contact terminals <NUM> are connected to the piezoelectric actuator <NUM>. Each contact terminal <NUM> is electrically connected to the substrate <NUM> through one conductive member <NUM>, and there may be no direct contact between two conductive members <NUM>. The conductive member <NUM> may be particularly made of a conductive material such as a copper foil.

In an example, the conductive member <NUM> is arranged on the outer surface of the lens barrel <NUM> to facilitate the fabrication of the conductive member <NUM> on the lens barrel <NUM>. For example, the outer surface of the lens barrel <NUM> is plated with the conductive member <NUM>. Furthermore, the plurality of conductive members <NUM> may be formed on the same side of an outer wall of the lens barrel <NUM> to facilitate the arrangement of the contact terminals <NUM> and the arrangement of wirings on the substrate <NUM>.

As illustrated in <FIG>, <FIG> and <FIG>, in some embodiments, the outer surface of the lens barrel <NUM> is provided with a wire groove <NUM> at a position corresponding to the conductive member <NUM>, and the conductive member <NUM> is arranged in the wire groove <NUM>. Since the conductive member <NUM> is arranged in the wire groove <NUM>, the conductive member <NUM> tends not to be scratched by external foreign matters so as not to affect the conductive performance thereof, and the conductive member <NUM> can be fixed in the wire groove <NUM> easily and tends not to come out thereof.

As illustrated in <FIG> and <FIG>, in some embodiments, the top face <NUM> is provided with a relief groove <NUM>, and the contact terminal <NUM> extends into the relief groove <NUM> and is electrically connected to the conductive member <NUM>. In some embodiments of the present disclosure, the conductive member <NUM> may also be arranged at the bottom of the relief groove <NUM>, and the contact terminal <NUM> extends into the relief groove <NUM> to be in contact the conductive member <NUM>. By providing the relief groove <NUM> in the lens barrel <NUM>, a space is actually provided for accommodating part of the contact terminal <NUM>, and thus the overall size of the imaging module <NUM> is reduced.

As illustrated in <FIG>, <FIG>, and <FIG>, in some embodiments, the lens barrel <NUM> includes a body <NUM> and a connecting protrusion <NUM>. The connecting protrusion <NUM> extends from the body <NUM>. The connecting protrusion <NUM> is also provided with the conductive member <NUM>.

The connecting protrusion <NUM> extends into the connecting groove <NUM> to electrically connect the conductive member <NUM> on the connecting protrusion <NUM> with the contact <NUM>.

In some embodiments of the present disclosure, the connecting protrusion <NUM> extends from the bottom face <NUM> in a direction running away from the top face <NUM>, and the conductive member <NUM> is arranged on the connecting protrusion <NUM>. The connecting groove <NUM> is formed in the package body <NUM>, and may extend through the package body <NUM>. The sensor assembly <NUM> is mounted to the substrate <NUM> while the connecting groove <NUM> is in alignment with the contact <NUM>, and the lens assembly <NUM> is mounted to the sensor assembly <NUM> while the connecting protrusion <NUM> is in alignment with the connecting groove <NUM>, so as to quickly align a mounting direction and prevent a reverse mounting. After the connecting protrusion <NUM> extends into the connecting groove <NUM>, the conductive member <NUM> is adjacent to or in contact with the contact <NUM>, and the conductive member <NUM> can be further soldered with the contact <NUM> by a soldering tin <NUM>, so as to increase the reliability of the electric connection.

As illustrated in <FIG>, in some embodiments, the adjustable lens assembly <NUM> further includes a frame <NUM>. The frame <NUM> is arranged on the lens barrel <NUM>, and the piezoelectric actuator <NUM> and the adjustable lens <NUM> are received in the frame <NUM>.

The amount of deformation of the adjustable lens <NUM> is proportional to the magnitude of the electrical signal acting on the piezoelectric actuator <NUM>.

The whole lining <NUM> may have an annular shape and surround the adjustable lens <NUM>. The lining <NUM> is received in the accommodating space <NUM>, and arranged between the adjustable lens <NUM> and the frame <NUM>.

The supporting member <NUM> may be made of transparent glass. When the adjustable lens <NUM> deforms, the side of the adjustable lens <NUM> attached to the supporting member <NUM> may not deform due to the restriction of the supporting member <NUM>. That is, the curvature of the side of the adjustable lens <NUM> attached to the supporting member <NUM> may not be changed so that the amount of deformation is concentrated on the side of the adjustable lens <NUM> attached to the membrane <NUM>.

The fixing member <NUM> is fixed to the frame <NUM>. In some embodiments of the present disclosure, the fixing member <NUM> is fixed to a side of the frame <NUM> facing away from the lens barrel <NUM>. The fixing member <NUM> may be configured to fix the lining <NUM> in the accommodating space <NUM> so as to prevent elements such as the lining <NUM>, the adjustable lens <NUM>, etc. from coming out of the accommodating space <NUM>.

When the light entering the imaging module <NUM> passes through the adjustable lens assembly <NUM>, the light may sequentially pass through a first light-passing hole <NUM> in the fixing member <NUM>, the supporting member <NUM>, the adjustable lens <NUM>, the membrane <NUM>, and a second light-passing hole <NUM> in the piezoelectric actuator <NUM>.

As illustrated in <FIG>, <FIG>, and <FIG>, in some embodiments, the adjustable lens assembly <NUM> further includes a conductive shielding member <NUM>.
