Referring to fig. 1, the electronic device includes a main body 100 and a camera module 200, wherein the camera module 200 is disposed on the main body 100 and is used for capturing images.

The body 100 includes a housing 101 and a display 110 connected to the housing 101, wherein an accommodating space is formed between the housing 101 and the display 110, the accommodating space is used for accommodating internal parts of the electronic device, and the housing 101 can protect the internal parts of the electronic device.

The camera module 200 can be installed on the housing 101, and when shooting is needed, the camera module 200 can receive external light to image.

As shown in fig. 2 and 3, the camera module 200 includes a lens group 210 for processing light and a light sensor 220 for receiving the light processed by the lens group 210 to form an image. The photosensor 220 has a photosensitive area 220a, and the photosensitive area 220a can generate photoelectric effect when being irradiated by light to perform imaging.

The light sensor 220 may be a color light sensor, a monochromatic light sensor, an infrared light sensor, a gray sensor, and the like, divided from colors.

Referring to fig. 4, when the lens group 210 and the optical sensor 220 are assembled to form the camera module 200 according to the optical path requirement, the plane of the photosensitive area 220a of the optical sensor 220 is substantially perpendicular to the imaging optical axis 200b, specifically, when the camera module 200 performs the photographing, the external light is incident on the photosensitive area 220a of the optical sensor 220 along the direction of the imaging optical axis 200b, so that the photosensitive area 220a is illuminated by the light, it is noted that "along the imaging optical axis 200 b" of the camera module 200 does not mean that the propagation direction of all the light incident on the optical sensor 220 is completely coincident with or parallel to the direction of the imaging optical axis 200b, for example, as shown in fig. 2, some of the light incident on the optical sensor 220 along the imaging optical axis 200b of the camera module 200 are coincident with or parallel to the direction of the imaging optical axis 200b, and some of the light are from the imaging optical axis 200b, as long as the light can enter the optical sensor 220 and the imaging optical sensor 220 is suitable for the imaging.

In , the camera module 200 may be fixedly disposed in the housing 101, and the housing 101 is provided with a light-transmitting member or a light-transmitting region for allowing light from outside the housing 101 to enter the camera module 200, so as to meet the shooting requirement of the camera module 200. the light-transmitting member may be transparent plastic or transparent glass, the housing 101 may also be partially made of transparent material to form the light-transmitting region, or may be made of transparent material, so that the light can penetrate into the electronic device from the outside and enter the light-incident surface 200a of the camera module 200, so as to meet the shooting requirement of the camera module 200.

In other embodiments, the camera module 200 can be movably disposed on the body 100. for example, the body 100 has a receiving slot for receiving the camera module 200, the camera module 200 can move relative to the body 100 and can be selectively located in a receiving state and an extending state, in the receiving state, the camera module 200 is located in the receiving slot, and the camera module 200 is shielded by the housing 101 at the periphery of the body 100, so as to prevent the camera module 200 from being exposed to the outside and spoil the overall appearance of the electronic device, in the extending state, the camera module 200 extends out of the receiving slot, so that the external light can be incident into the camera module 200 through the imaging optical axis 200b of the camera module 200, so as to meet the imaging requirement of the camera module 200.

It should be noted that, the camera module 200 can be used for front-end shooting, for example, in the electronic device shown in fig. 1, the light incident surface 200a of the camera module 200 is exposed to the side of the displayable region 110a of the display screen 110. in other embodiments , the position of the camera module 200 in the main body 100 is adjusted, so that the light incident surface 200a faces away from the side of the displayable region 110a of the display screen 110, i.e., the camera module 200 can be used for rear-end shooting, and the shooting angle of the camera module 200 relative to the main body 100 is not limited herein.

Referring to fig. 2, in embodiments, the lens assembly 210 includes a lens 211, a second lens 212, a liquid lens 213 and an electrode set 214 a.

The optical axis of the th lens 211 is coaxial with the optical axis of the second lens 212, and the liquid lens 213 is disposed between the th lens 211 and the second lens 212 along the extending direction of the optical axis of the th lens 211, to be exact, the optical axes of the th lens 211 and the second lens 212 define the imaging optical axis 200b of the camera module 200, that is, the th lens 211, the liquid lens 213 and the second lens 212 are sequentially disposed along the imaging optical axis 200b of the camera module 200.

Referring to fig. 4, after the lens group 210 is assembled to the camera module 200, the light sensor 220 is located on the side of the second lens 212 facing away from the th lens 211, and external light can pass through the th lens 211, the liquid lens 213 and the second lens 212 in sequence along the imaging optical axis 200b of the camera module 200 and then be incident on the light sensor 220, so that the photosensitive area 220a of the light sensor 220 is imaged when being illuminated to meet the shooting requirement.

The electrode set 214a is used to adjust the state of the liquid lens 213 when the power is turned on, so that the light passing through the liquid lens 213 exhibits different focuses or divergences.

As shown in fig. 9 to 11, the liquid lens 213 includes a sealed cavity, and a conductive fluid 213a and an insulating fluid 213b filling the sealed cavity.

The sealed cavity may be formed by enclosing the light incident side 2131, the peripheral side and the light exit side 2132, wherein the light incident side 2131 and the light exit side 2132 can allow light to pass through, for example, a transparent glass plate or a plastic plate is used to form the light incident side 2131 and the light exit side 2132. The periphery is enclosed between the light incident side 2131 and the light emergent side 2132, and the inner wall is provided with the hydrophobic layer 2133, so that the conductive fluid 213a has a more precise contact angle regulation effect when generating an electrowetting effect. The material of the hydrophobic layer 2133 may be an amorphous fluoropolymer such as AF1600, AF1601 or AF1600X, supplied by DuPont, or any other low surface energy polymer.

When the propagation direction of light needs to be adjusted by the liquid lens 213, electricity can be conducted to the conductive fluid 213a through the electrode group 214a to generate an electrowetting effect, so as to change a contact angle between the conductive fluid 213a and the peripheral side, that is, a contact angle between the interface 213c and the side wall of the sealed cavity, so that the shape of the interface 213c is changed, and further, light passing through the interface 213c is refracted to different degrees.

Next, the optical principle of the liquid lens 213 will be further described only in three states of the liquid lens 213 shown in fig. 9 to 11.

As shown in fig. 9, the th electrode 2134 electrically connected to the conductive fluid 213a and the second electrode 2135 electrically connected to the sealed cavity form the electrode group 214a, since the conductive fluid 213a is electrically isolated from the side wall of the sealed cavity by the hydrophobic layer 2133, when the voltage V applied to the th electrode 2134 and the second electrode 2135 of the electrode group 214a is th voltage value, for example, 0V, the conductive fluid 213a does not generate an electrowetting effect, the interface 213c between the conductive fluid 213a and the insulating fluid 213b is in the th state, the interface 213c presents a convex arc surface on the side relative to the conductive fluid 213a, and since the refractive indexes of the conductive fluid 213a and the insulating fluid 213b are different, light is refracted when passing through the interface 213c, and parallel light is diffused.

Referring to fig. 10, when the voltage V applied to the th electrode 2134 and the second electrode 2135 of the electrode set 214a is a second voltage value, for example, 37V, the conductive fluid 213a generates an electrowetting effect, the interface 213c between the conductive fluid 213a and the insulating fluid 213b will be in a second state, the interface 213c is in a plane, and the propagation direction of the parallel light ray passing through the interface 213c along the optical axis is unchanged.

Referring to fig. 11, when the voltage V applied to the th and

second electrodes

2134 and 2135 of the electrode group 214a is a third voltage value, for example, 50V, the conductive fluid 213a generates an electrowetting effect, the interface 213c between the conductive fluid 213a and the insulating fluid 213b is in a third state, the interface 213c is in a concave arc surface on the side with respect to the conductive fluid 213a, and light propagating along the optical axis is refracted and focused when passing through the interface 213c due to the different refractive indexes of the conductive fluid 213a and the insulating fluid 213 b.

By changing the voltage V applied to the conductive fluid 213a by the th electrode 2134 and the second electrode 2135 of the electrode set 214a, the contact angle between the conductive fluid 213a and the side wall of the sealed cavity is changed, and the shape of the interface 213c is changed, so as to adjust the emitting direction of the light.

The degree of change in the shape of the interface 213c, , is related to the amount of voltage applied by the electrode set 214a, is also related to the material used for the conductive fluid 213 a. different materials will have different electrowetting effects at the same voltage, i.e., the interface 213c will have different shapes at the same th voltage, second voltage and third voltage with different conductive fluids 213 a.

In , the conductive fluid 213a may be deionized water and the insulating fluid 213b may be silicone oil, but the materials of the conductive fluid 213a and the insulating fluid 213b are not limited herein, and only the electrowetting effect is required to change the shape of the interface 213 c.

When the interface 213c is deformed to be in different forms, the liquid lens 213 will focus or scatter light to different degrees, and further the electrowetting of the electrode group 214a on the conductive fluid 213a is used to change the contact angle of the interface 213c, so that the direction of the light emitted by the liquid lens 213 can be adjusted, and the light finally incident on the photosensitive area 220a of the optical sensor 220 and imaged is always the light modulated by the liquid lens 213, therefore, from the perspective of imaging performed by the optical sensor 220, the light modulation performed by the liquid lens 213 will enable the optical sensor 220 to obtain different shooting fields. For example, when the liquid lens 213 is used to properly focus light, the light emitted from the liquid lens 213 enters the photosensitive area 220a of the optical sensor 220 after passing through the second lens 212, and the light sensing area 220a of the optical sensor 220 obtains light of a distant scene to achieve long-range shooting or the light sensing area 220a of the optical sensor 220 obtains light of a close scene to achieve short-range shooting as the liquid lens 213 focuses light differently, i.e., adjusts the focal length.

In this way, the liquid lens 213 is only electrowetting inside the conductive fluid 213a, and the position of the contact angle of the interface 213c is not changed, so that the light propagation direction can be changed to meet the focusing or anti-shake requirement without moving the liquid lens 213. Because the liquid lens 213 does not need to move when dimming, the response is fast and sensitive, so that a faster dimming effect can be obtained, and when adjusting a larger lens, a power source with a large volume is not needed, and only the electrode group 214a is needed to provide electrowetting voltage for the conductive fluid 213a, so that the camera module 200 can still provide a better focusing or anti-shaking effect under the condition of maintaining a small structure.

In , the electronic device further includes a detection module for detecting the shaking information of the camera module 200 and a driving module for adjusting the working state of the electrode set 214a according to the shaking information, specifically, the driving module is used to adjust the electrode set 214a to provide different voltages for the conductive fluid 213a so as to generate an electrowetting effect to adjust the contact angle between the interface 213c and the side wall of the sealed cavity, and then change the shape of the interface 213c to meet the requirement of optical anti-shaking by adjusting the light.

The th lens element 211 and the second lens element 212 include a plurality of lens groups formed by convex and/or concave lens elements for focusing or filtering light rays, and accordingly, the th lens element 211 includes a plurality of lens groups formed by convex and/or concave lens elements for focusing or diverging light rays emitted from the liquid lens element 213.

Taking the th lens 211 as an example, in embodiments, the th lens 211 includes convex lenses and concave lenses arranged along an optical axis, light passing through the liquid lens 213 is focused at after entering the convex lens of the th lens 211, and then is diverged while passing through the concave lens, so that stray light of different frequency bands in the light can be separated from light entering the photosensitive area 220a of the optical sensor 220, and the stray light is prevented from entering the photosensitive area 220a of the optical sensor 220 to affect an imaging effect.

The specific structural forms of the lens 211 and the second lens 212 are not limited herein as long as the liquid lens 213 can process the propagation direction of the light between the two, so that the light finally incident to the photosensitive area 220a of the optical sensor 220 can meet the imaging requirements.

The camera module 200 further includes a lens holder 216 and a mounting plate 214 disposed in the lens holder 216, wherein the th lens 211 and the second lens 212 are both mounted in the lens holder 216 and respectively located at two sides of the mounting plate 214, and the liquid lens 213 is connected to the mounting plate 214. the lens holder 216 is used as a mounting carrier for the th lens 211 and the second lens 212, so as to facilitate structural integration, so that when the camera module 200 is manufactured, the th lens 211 and the second lens 212 can be assembled to the body through the lens holder 216, thereby realizing the mounting and fixing of the th lens 211 and the second lens 212, and being integrally assembled to the camera module 200 as lenses.

It should be noted that the mounting plate 214 is used as a mounting carrier of the liquid lens 213, but the mounting plate 214 itself does not affect the light entering from the th lens 211 to the liquid lens 213. the mounting plate 214 may be made of a transparent glass plate or plastic plate, the light transmittance of which is above 70%, that is, the light exits from the th lens 211, at least 70% of the light can pass through the mounting plate 214, so that enough light enters the liquid lens 213 and enters the photosensitive area 220a of the optical sensor 220 from the second lens 212. furthermore, the mounting plate 214 may not be made of a transparent material, but a through hole for the light to pass through is formed on the mounting plate 214, and after the liquid lens 213 is mounted and fixed by the mounting plate 214, the light can still enter the liquid lens 213 through the through hole.

The mounting board 214 may electrically connect the electrical signals of the electrode group 214a to an external circuit by means of wires. For example, a lead 214b is disposed on an outer side of the lens holder 216, and the lead 214b is electrically connected to the electrode group 214a through an internal trace of the mounting board 214, so as to be electrically connected to an external circuit through the lead 214b after the lens holder 216 is assembled to the camera module 200. For example, the camera module 200 includes a circuit board 200c, the optical sensor 220 is disposed on the circuit board 200c, and the leads 214b are electrically connected to the circuit board 200 c. The optical sensor 220 is mounted on the circuit board 200c in the form of a patch, and the optical sensor 220 may be adhered to the circuit board 200c by glue.

It should be noted that the circuit board 200c may be a rigid circuit board or a flexible circuit board, and the type of the circuit board 200c is not limited herein. It is understood that the circuit board 200c may be printed with a circuit to electrically connect with the optical sensor 220, so that an electrical signal generated when the photosensitive region 220a of the optical sensor 220 is illuminated to generate an optoelectronic effect may be transmitted from the circuit board 200c to a corresponding functional module such as a controller, an image processor, a memory, etc.

The lens holder 216 is connected to the circuit board 200c and covers the optical sensor 220 therein, so that the light emitted from the second lens 212 can enter the photosensitive area 220a of the optical sensor 220, and the light optically processed by the lens group 210 enters the photosensitive area 220a for imaging.

In embodiments, the optical filter 215 is disposed in the lens holder 216, and the optical filter 215 is located on a side of the second lens 212, which is farther from the th lens 211, in an extending direction of the optical axis of the second lens 212, and then when the lens group 210 is mounted in the camera module 200, the optical filter 215 is located between the second lens 212 and the optical sensor 220 and is used for filtering the light emitted from the second lens 212, so that the light incident on the optical sensor 220 has no stray light interference, and a good imaging effect is obtained.

The th lens 211 can be screwed to the th holder 2161, that is, the 1 th mounting hole 216a of the 0 th holder 2161 is a threaded hole, and correspondingly, the periphery of the th lens 211 is provided with an external thread matching with the th mounting hole 216a, so that the th lens 211 can be screwed into the th mounting hole 216 a. in this way, the th lens 211 can be screwed to the th holder 2161, and this screwing way also achieves the focusing requirement of , so that the distance between the th lens 211 and the optical sensor 220 can be adjusted within a proper range, and the imaging requirement of the light sensing area 220a of the optical sensor 220 can be satisfied.

The th lens 211 can be mounted on the th holder 2161 by clipping, and the second lens 212 can be connected to the second holder 2162 by the same connection method as the th lens 211, which will not be described herein.

As shown in fig. 5, the bracket 2161 and the second bracket 2162 are injection molded on the body, the connection between the bracket 2161 and the second bracket 2162 forms a mounting detent 216d, and the mounting plate 214 is detachably mounted on the mounting detent 216d, so that the bracket 2161 and the second bracket 2162 are not required to be connected by screws or gluing, the assembly is simplified, and the production cost is reduced, meanwhile, the body molding structure is more stable and less prone to loosening, thereby ensuring that the relative position between the lens 211 and the second lens 212 is not affected by the loosening of the bracket 2161 and the second bracket 2162, and effectively ensuring the imaging stability of the camera module 200 during shooting.
