The lens barrel 151 may be fixedly connected to the base 110 by a screw connection, or an adhesive or a snap connection. Of course, the lens barrel 151 is not necessary, and the plurality of lenses 153 may be directly mounted to the holder body 110. Further, the liquid lens 120 includes a substrate 121 and a light-transmitting body 123 disposed on the substrate 121, and the substrate 121 is fixedly connected to the seat 110 and covers the light inlet 111.

Specifically, in some embodiments, the connecting portion 131 is an elastic sheet, the pressing structure 130 includes a magnet 135 and a coil 137, the magnet 135 is connected to the base 110 and is used for providing a magnetic field, the coil 137 is connected to the moving portion 133 and is located in the magnetic field, when the coil 137 is powered on, the coil can interact with the magnetic field and drive the moving portion 133 to move so as to press the light-transmitting body 123, and the connecting portion 131 can be used for returning the moving portion 133. In other embodiments, the connecting portion 131 is a spring, and the moving portion 133 comprises a magnetostrictive material comprising Laves phase rare earth iron compound RFe₂Etc., magnetostrictive materials can deform telescopically in a magnetic field. The pressing structure 130 includes an electromagnet fixedly connected to the base 110 and capable of generating a magnetic field when the electromagnet is powered on to drive the moving portion 133 to deform and press the light-transmitting body 123, and the connecting portion 131 is used for returning the moving portion 133. In other embodiments, the connecting portion 131 is a spring, and the moving portion 133 includes a piezoelectric material, which can be deformed by an electric field.

The structure of the extrusion structure 130 is simple and easy to control, and the volume of the extrusion structure 130 is relatively small, which is beneficial to miniaturization design. Since the driving force required for the deformation of the liquid is relatively small, the liquid lens 120 can be driven to generate a relatively large deformation under relatively low power consumption, so as to meet the focusing or anti-shake requirements of the camera module 100, and a faster response speed can be obtained. Particularly, for the camera module 100 with high pixels, the volume of the lens group 150 is relatively large, and after the liquid lens 120 and the extrusion structure 130 of the present application are adopted, it is not necessary to set a driving mechanism to drive the lens group 150 to move, so that the structure of the camera module 100 can be simplified, the power consumption of the camera module 100 can be reduced, the manufacturing difficulty and the manufacturing cost of the camera module 100 can be reduced, and the miniaturization design of the camera module 100 can be facilitated.

Further, the camera module 100 includes a filter 160 and a circuit board 170, the filter 160 and the circuit board 170 are respectively connected to the base 110, the filter 160 is located between the lens assembly 150 and the image sensor 140, and the image sensor 140 is electrically connected to the circuit board 170. The circuit board 170 may be provided with a flexible circuit board, and is electrically connected to the main board of the terminal device 10 through the flexible circuit board, so as to transmit the image data collected by the camera module 100 to the processor of the terminal device 10 for further processing. The optical filter 160 can filter infrared light, so that the camera module 100 can obtain better shooting quality.

The number of the pressing structures 130 may be multiple, for example, the pressing structures 130 may include two, and the two pressing structures 130 are disposed on two sides of the lens group 150 opposite to each other. For another example, the pressing structures 130 may include three pressing structures 130, and the three pressing structures 130 are disposed in the circumferential direction of the lens group 150 at equal intervals, that is, the central angle of two adjacent pressing structures 130 with respect to the optical axis 152 of the lens group 150 is 120 degrees. Referring to fig. 3 and 4, in the embodiment of the present application, the number of the pressing structures 130 is four, and the four pressing structures 130 are disposed at equal intervals in the circumferential direction of the lens group 150, i.e., the central angle of two adjacent pressing structures 130 with respect to the optical axis 152 is 90 degrees. Such a pressing structure 130 can control two pressing structures 130 arranged opposite to each other as a group, so that the deformation of the liquid lens 120 can be easily controlled, and relatively high control accuracy can be obtained. Referring to fig. 3, in some embodiments, the cross-sectional profile of the holder body 110 is rectangular, and the pressing structures 130 are disposed corresponding to four sides of the rectangle. For example, a rectangle may have magnets 135 disposed on each side of the rectangle, with a coil 137 disposed on each magnet. Referring to fig. 4, in other embodiments, the crush structures 130 are disposed at four corners of a rectangle. For example, a magnet 135 is disposed at each corner of the rectangle, and a coil 137 is disposed corresponding to each magnet 135. Other types of extrusion structures 130 can be provided with reference to the above embodiments, and are not described in detail herein. Of course, in other embodiments, the number of the pressing structures 130 may be 4 or more, so as to provide a plurality of force application points to the light-transmitting body 123 of the liquid lens 120, thereby realizing more accurate control.

Referring to fig. 2, in the first embodiment of the present application, the lens group 150 is disposed on a side of the moving portion 133 away from the liquid lens 120, and a projection of the moving portion 133 is spaced from a projection of the lens group 150 in an extending direction of an optical axis 152 of the lens group 150. That is, the moving portion 133 is located between the lens group 150 and the substrate 121 of the liquid lens 120, and is movable between the substrate 121 and the lens group 150. The moving portions 133 can be integrally connected by using a spring, so that the pressing structures 130 have a relatively stable structure and can be easily assembled with the housing 110. The plurality of moving portions 133 may surround to form a through hole, and the light transmitted through the light-transmitting body 123 may pass through the through hole and enter the lens assembly 150.

Referring to fig. 5, in the second embodiment of the present application, the moving portion 133 is disposed at the outer periphery of the lens group 150, and the projection of the moving portion 133 and the projection of the lens group 150 at least partially overlap in the extending direction of the optical axis 152 of the lens group 150. That is, at least a part of the structure of the lens group 150 is surrounded by the moving portion 133 so that the lens group 150 and the moving portion 133 have an overlapping region in projection in the extending direction of the optical axis 152. With this arrangement, the lens group 150 is prevented from overlapping the moving portion 133 in the extending direction of the optical axis 152, and thus the thickness of the camera module 100 in the extending direction of the optical axis 152 can be reduced, so that the internal structure of the camera module 100 is more compact, and the miniaturization of the camera module 100 is facilitated.

In the camera module 100, the extrusion structure 130 can extrude the liquid lens 120 to deform the liquid lens 120, and the radian of the surface of the liquid lens 120 is changed after the liquid lens 120 is deformed, so that the angle of light passing through the liquid lens 120 can be adjusted, and focusing or anti-shaking functions can be realized. The pressing structure 130 and the liquid lens 120 have relatively small volumes and simple structures, and the deformation of the fluid is easy to control, so that the deformation of the liquid lens 120 can be easily controlled at relatively low power consumption to obtain a faster focusing speed or a better anti-shake effect. After the liquid lens 120 is adopted, a driving mechanism is not required to be arranged to push the lens group 150 to move, so that the structure of the camera module 100 can be simplified, and the difficulty and the cost of manufacturing are reduced. Of course, in other embodiments, the lens assembly 150 may be provided with a driving mechanism such as a voice coil motor, so as to enable the lens assembly 150 to move relative to the base 110, or to enable one or more lenses 153 in the lens assembly 150 to move relative to the base 110, so as to achieve better focusing or anti-shake effect. It is understood that since the camera module 100 is provided with the liquid lens 120 and the pressing structure 130, the requirements for the voice coil motor may be reduced. For example, the control accuracy of the voice coil motor can be reduced to reduce the manufacturing difficulty of the voice coil motor and the manufacturing cost of the camera module 100.
