In this embodiment, the camera assembly 100 is rear-mounted, or in other words, the camera assembly 100 is disposed on the back of the electronic device 1000 so that the electronic device 1000 can perform rear-facing photography. In the example of FIG. 1 , the camera assembly 100 is disposed at the upper left corner of the casing 102 . Of course, it can be understood that the camera assembly 100 may be disposed at other positions such as the upper-middle position or the upper-right position of the casing 102 . The location where the camera assembly 100 is disposed on the housing 102 is not limited to the examples of the present application.

Referring to FIG. 2 and FIG. 3 , the camera assembly 100 includes a decorative component 10 , a first camera module 20 , a second camera module 30 and a bracket 40 . The decorative element 10 is disposed on the casing 102 and protrudes from the surface of the casing 102 . The first camera module 20 and the second camera module 30 are both disposed inside the casing 102 . Both the first camera module 20 and the second camera module 30 are disposed close to the decoration member 10 . The first camera module 20 and the second camera module 30 are both disposed in the bracket 40 and fixedly connected to the bracket 40 .

The decoration piece 10 is arranged above the bracket 40 , specifically, the decoration piece 10 may abut on the bracket 40 , or may be arranged at a distance from the bracket 10 . The bracket 40 can reduce the impact on the first camera module 20 and the second camera module 30 , and improve the service life of the first camera module 20 and the second camera module 30 .

The decorative element 10 can be made of metal material, for example, the material of the decorative element 10 is stainless steel, and the decorative element 10 can be processed by a polishing process to form a bright surface, so as to make the decorative element 10 more beautiful.

Please refer to FIG. 4 , the decoration member 10 is formed with a through hole 11 , and both the first camera module 20 and the second camera module 30 are exposed to the decoration member 10 from the through hole 11 , or in other words, the first camera module 20 and the second camera module The camera modules 30 collect external images through the through holes 11 . Specifically, in this embodiment, the through hole 11 includes a first sub-hole 111 and a second sub-hole 112 , and the first sub-hole 111 and the second sub-hole 112 are arranged at intervals. In other words, the first sub-hole 111 and the second sub-hole 112 are disconnected.

Of course, in other embodiments, the first sub-hole 111 and the second sub-hole 112 may communicate to form an integral hole. The first camera module 20 collects external images through the first sub-hole 111 , and the second camera module 30 collects external images through the second sub-hole 112 . In this embodiment, the first sub-hole 111 is a circular hole, and the second sub-hole 112 is a square hole.

In other embodiments, the shapes of the first sub-hole 111 and the second sub-hole 112 are not limited to the shapes in the figures. For example, the first sub-hole 111 and the second sub-hole 112 are both circular holes; for another example, the first sub-hole 111 and the second sub-hole 112 are both square holes.

The decorative piece 10 includes a decorative ring 12 and a bead 13 , and the bezel 13 extends from the bottom of the decorative bezel 12 in a direction away from the decorative bezel 12 . The through hole 11 is formed in the decorative ring 12 and penetrates through the decorative ring 12 and the flange 13 . The decorative ring 12 is mounted on the casing 102 , and the flange 13 abuts on the casing 102 , as shown in FIG. 10 . In this way, the raised edge 13 can limit the position of the decorative element 10 to prevent the decorative element 10 from moving out of the casing 102 .

In one example, when installing the decorative element 10 , the decorative element 10 is inserted outward from the inside of the casing 102 , and when the flange 13 abuts against the inner surface of the casing 102 , the decorative element 10 is installed to a predetermined position. The decorative piece 10 can be fixed on the casing 102 by adhesive, or the decorative piece 10 can be interference fit with the casing 102 , so that the decorative piece 10 is not easy to fall off from the casing 102 .

The decorative piece 10 may be an integrally formed structure formed by the decorative ring 12 and the flange 13 , for example, the decorative piece 10 is formed by cutting. In addition, the decorative ring 12 and the bead 13 may also be a separate structure, or in other words, the decorative ring 12 and the bezel 13 are first formed into two independent elements, and then assembled together by welding and other processes to form the decorative piece 10 .

It should be pointed out that, in other embodiments, the convex edge 13 may be omitted, that is, in this embodiment, the decorative element 10 only includes the structure of the decorative ring 12 .

The first camera module 20 and the second camera module 30 are arranged side by side, that is to say, the second camera module 30 is arranged on one side of the first camera module 20 . In this embodiment, the first camera module 20 and the second camera module 30 are arranged in a line shape, or in other words, the first camera module 20 and the second camera module 30 are arranged along the same straight line. In other embodiments, the first camera module 20 and the second camera module 30 may be arranged in an L shape. The first camera module 20 and the second camera module 30 may be arranged at intervals, or may be abutted against each other.

In this embodiment, the first camera module 20 is located on the right side of the second camera module 30 , or in other words, the first camera module 20 is closer to the middle of the electronic device 1000 than the second camera module 30 . Of course, it can be understood that in other embodiments, the positions of the first camera module 20 and the second camera module 30 can be interchanged, or the first camera module 20 is located on the left side of the second camera module 30 .

In the first camera module 20 and the second camera module 30, one of the camera modules can be a black and white camera, and the other camera module is an RGB camera; or one camera module is an infrared camera, and the other camera module is RGB camera; or one camera module is an RGB camera, and the other camera module is also an RGB camera; or one camera module is a wide-angle camera, and the other camera module is a telephoto camera, etc.

In other embodiments, the second camera module 30 may be omitted, or the electronic device 1000 may include more than three camera modules.

Referring to FIGS. 5-7 , in this embodiment, the first camera module 20 includes a housing 21 , a light converting element 50 , a first lens assembly 24 , a moving element 25 , a first image sensor 26 and a driving mechanism 27 .

The light converting element 50 , the first lens assembly 24 , and the moving element 25 are all arranged in the housing 21 . The light converting element 50 has an integral molding structure, and the light converting element 50 includes a light converting portion 22 and a mounting portion 23 connected to the light converting portion 22 . The first lens assembly 24 is accommodated in the moving element 25 . The moving element 25 is provided on the side of the first image sensor 26 .

The drive mechanism 27 connects the moving element 25 with the housing 21 . After the incident light enters the housing 21 , it is turned by the light converting portion 22 , and then passes through the first lens assembly 24 to reach the first image sensor 26 , so that the first image sensor 26 obtains an external image. The driving mechanism 27 drives the moving element 25 to drive the movement of the first lens assembly 24, so that the first camera module 20 can achieve the effect of focusing.

The casing 21 is substantially square-shaped, and the casing 21 is provided with a light inlet 211 , and incident light enters the first camera module 20 from the light inlet 211 . That is to say, the light diverting part 22 is used to divert the incident light incident from the light inlet 211 and transmit it to the first image sensor 26 . Therefore, it can be understood that the first camera module 20 is a periscope lens module. Compared with the vertical lens module, the height of the periscope lens module is smaller, so that the overall thickness of the electronic device 1000 can be reduced. The vertical lens module means that the optical axis of the lens module is a straight line, or in other words, the incident light is transmitted to the photosensitive device of the lens module along the direction of a straight optical axis.

It can be understood that the light inlet 211 is exposed through the through hole 11 so that the external light enters the first camera module 20 from the light inlet 211 after passing through the through hole 11 .

Referring to FIG. 8 , in this embodiment, in the width direction of the first camera module 20 , the casing 21 is formed with a groove 212 on one side of the light inlet 211 , and the decorative element 10 is covered above the light inlet 211 and Partially snaps into groove 212 .

Referring to FIG. 10 , if the groove is omitted, in order to make the overall thickness of the electronic device thinner, the periscope camera module 20a partially extends into the decoration member 10a in the width direction. Compared with the width of the vertical camera module, the size of the decorative element 10a is larger at this time, which is not conducive to the appearance of the electronic device, and also makes the electronic device not compact enough.

Please refer to FIG. 5 and FIG. 8 again, and in this embodiment, the groove 212 is formed on one side of the light inlet 211 , and the decorative element 10 is covered above the light inlet 211 and partially clamped into the groove 212 , not only The width dimension of the decorative part 10 is made smaller, and the overall height dimension of the camera assembly 100 can also be reduced, which is beneficial to the compact structure and miniaturization of the camera assembly 100 .

Specifically, the housing 21 includes a top wall 213 and side walls 214 . The side wall 214 is formed to extend from the side edge 2131 of the top wall 213 . The top wall 213 includes two opposite sides 2131 , the number of the side walls 214 is two, and each side wall 214 extends from a corresponding side 2131 , or in other words, the side walls 214 are connected to the opposite sides of the top wall 213 respectively. sides. The light inlet 211 is formed on the top wall 213 , the groove 212 is formed at the connection between the top wall 213 and the side wall 214 , and the decorative element 10 abuts on the top wall 213 . In this way, the groove 212 can be easily formed, which is beneficial to the manufacture of the housing 21 . In one example, the groove 212 is a profile of the housing 21 , that is, the groove 212 may be formed by stamping.

In one example, a part of the bottom of the decorative ring 12 is accommodated in the groove 212 , and a part of the decorative ring 12 abuts on the top wall 213 . In other words, the decorative ring 12 and the housing 21 form a complementary structure, and the decorative ring 12 and the housing 21 are fitted with each other, so that the matching structure of the decorative element 10 and the housing 21 is more compact.

In this embodiment, a groove 212 is formed at the connection between each side wall 214 and the top wall 213 . In other words, the number of grooves 212 is two. Of course, in its embodiment, the number of the grooves 212 may also be single, that is, a groove 212 is formed at the connection between one of the side walls 214 and the top wall 213 .

In this embodiment, the grooves 212 are elongated, and the grooves 212 extend along the length direction of the first camera module 20 . In this way, the groove 212 is more compactly matched with the decorative element 10 . In some embodiments, the grooves 212 may be arc-shaped, and the arc-shaped grooves 212 surround the light inlet 211 . Of course, in other embodiments, the structure and shape of the groove 212 are not limited to the above examples, as long as the decorative element 10 and the first camera module 20 form a complementary structure to reduce the size of the decorative element 10 .

Please refer to FIG. 6 , FIG. 7 and FIG. 12 , the light-converting element 50 is integrally formed. The light-converting element 50 includes a light-converting part 22 and a mounting part 23 connected to the light-converting part 22 . The incident light incident from the optical port 211 is turned and transmitted to the first image sensor 26 so that the first image sensor 26 can sense the incident light outside the first camera module 20 , and the mounting portion 23 can be rotated relative to the housing 21 to adjust the light converting portion. 22 is the direction in which the incident light is turned, so that the first camera module 20 can achieve optical anti-shake.

In this way, due to the integral molding structure of the light converting element 50 , the problem of the light converting portion 22 falling off during use or after being dropped can be reduced, which is beneficial to improve the reliability of the light converting element 50 .

In one example, a blank part may be used, and then the light converting element 50 may be formed by a cutting process.

In another example, the molten material can be injected into the mold, and the integrally formed light converting element 50 can be formed after the molten material is cooled.

Of course, the integrally formed light converting element 50 can also be made in other ways, and the above examples are only for explanation and do not represent a limitation on the integrally formed process.

The light diverting part 22 has a reflective surface 226 for diverting and reflecting the incident light to the first image sensor 26 . In one example, the reflective surface 226 rotates the incident light by 90° and reflects it to the first image sensor 26 . In another example, the reflective surface 226 rotates the incident light by 45° and reflects it to the first image sensor 26 .

Referring to FIG. 12 , it is assumed that the light converting element 50 is cut on a plane that coincides with the reflective surface 226 , and the light converting element 50 is cut into the light converting portion 22 and the mounting portion 23 along the dotted line in FIG. 12 .

There is a gap 232 between the reflective surface 226 and the mounting portion 23 . In this way, the gap 232 can prevent the light from being refracted to the mounting portion 23 to cause light loss.

Since the light converting element 50 is integrally formed, the material of the mounting portion 23 is the same as that of the light converting portion 22, and the mounting portion 23 has the function of refraction. The first camera module 20 of this embodiment utilizes the refractive index difference between light in the air and the light converting portion 22 to cause the light to be totally reflected on the reflective surface 226 and unable to enter the mounting portion 23. Therefore, the medium in the gap 232 may be Air.

Specifically, the void 232 may be processed on the integrally formed light converting element 50 by using a computer numerical control technology (Computerized Numerical Control, CNC), a laser or other methods.

The light converting part 22 may be a prism or a plane mirror. In one example, when the light converting portion 22 is a prism, the prism can be a triangular prism, and the cross section of the prism is, for example, a right-angled triangle, wherein the light is incident from one of the right-angled sides of the right-angled triangle, and after the reflection of the hypotenuse, the other side is reflected. A right-angled edge exits. It can be understood that, of course, the incident light can be refracted by the prism and then exit without being reflected. The prism can be made of materials with relatively good light transmittance such as glass and plastic. In one embodiment, one surface of the prism may be coated with a reflective material such as silver to reflect incident light.

It can be understood that when the light turning part 22 is a flat mirror, the flat mirror reflects the incident light so as to realize the turning of the incident light.

For more details, please refer to FIG. 6 and FIG. 12 , the light converting portion 22 has a light incident surface 222 , a light reflecting surface 226 and a light exit surface 228 . The light incident surface 22 is close to and faces the light inlet 211 , the reflective surface 226 is connected to the light incident surface 222 , and the light exit surface 228 is connected to the light incident surface 222 .

Specifically, the light passes through the light inlet 211 and enters the light turning portion 22 from the light incident surface 222, is reflected by the reflective surface 226, and finally exits the light turning portion 22 from the light exit surface 228, thereby completing the turning process.

As shown in FIG. 13, in the related art, due to the need to reflect incident light, the light-reflecting surface 226a of the light-reversing portion 22a is inclined with respect to the horizontal direction, and the light-reversing portion 22a has an asymmetric structure in the reflection direction of the light. The light has a certain angle of incidence, so the incident light cannot be incident on the lower part of the reflective surface 226a. Therefore, the part of the reflective surface 226a far from the light inlet is less or cannot reflect light.

Therefore, referring to FIG. 14 , the light-converting portion 22 according to the embodiment of the present application has cut edges and corners away from the light inlet relative to the light-converting portion 22a in the related art, which not only does not affect the effect of the reflected light of the light-converting portion 22 , but also The overall size of the light converting portion 22 is reduced.

In some embodiments, the angle α of the light-reflecting surface 226 relative to the light-incident surface 222 is inclined at 45 degrees.

In this way, the incident light is better reflected and converted, and has a better light conversion effect.

The light converting element 50 can be made of materials with relatively good light transmittance such as glass and plastic. In one embodiment, a reflective material such as silver may be coated on one surface of the light converting portion 22 to reflect incident light.

In some embodiments, the light incident surface 222 , the light reflecting surface 226 and the light exit surface 228 are all hardened to form a hardened layer.

When the light-converting element 50 is made of materials such as glass, the material of the light-converting element 50 itself is relatively brittle. 228 is hardened.

Furthermore, all surfaces of the light converting element 50 can be hardened to further improve the strength of the light converting element 50 . The hardening treatment is such as infiltration of lithium ions, and filming the above surfaces on the premise that the normal operation of the light converting element 50 is not affected.

In one example, the angle by which the light diverting portion 22 diverts the incident light incident from the light inlet 211 is 90 degrees. For example, the incident angle of the incident light on the reflection surface of the light converting portion 22 is 45 degrees, and the reflection angle is also 45 degrees. Of course, the angle at which the light turning portion 22 turns the incident light can also be other angles, such as 80 degrees, 100 degrees, etc., as long as the incident light can be turned to reach the first image sensor 26 .

In this embodiment, the number of the light diverting elements 50 is one. In this case, the incident light is diverted once and then transmitted to the first image sensor 26 . In other embodiments, the number of light diverting elements 50 is multiple. In this case, the incident light is diverted at least twice and then transmitted to the first image sensor 26 .

Please refer to FIG. 6 again, in one example, the light-reversing element 50 is integrally formed, the light-reversing element 50 is movably disposed in the housing 21 , and the light-reversing element 50 can rotate relative to the housing 21 to adjust the light-reversing portion 22 The direction in which incoming light is turned.

The light converting element 50 can rotate together toward the opposite direction of the shaking of the first camera module 20 , thereby compensating for the incident light deviation of the incident light of the light inlet 211 and realizing the effect of optical anti-shake.

The first lens assembly 24 is accommodated in the moving element 25 , and further, the first lens assembly 24 is disposed between the light converting element 50 and the first image sensor 26 . The first lens assembly 24 is used to image incident light on the first image sensor 26 . In this way, the first image sensor 26 can obtain images with better quality.

When the first lens assembly 24 moves as a whole along its optical axis, an image can be formed on the first image sensor 26 , so as to realize the focusing of the first camera module 20 . The first lens assembly 24 includes a plurality of lenses 241. When at least one lens 241 moves, the overall focal length of the first lens assembly 24 changes, so as to realize the zoom function of the first camera module 20. More, it is driven by the driving mechanism 27 The moving element 25 moves in the housing 21 for zooming purpose.

In the example of FIG. 6 , in some embodiments, the moving element 25 is cylindrical, and the plurality of lenses 241 in the first lens assembly 24 are fixed in the moving element 25 along the axial interval of the moving element 25 . In the example of FIG. 7 , the moving element 25 includes two clips 252 that sandwich the lens 241 between the two clips 252 .

It can be understood that since the moving element 25 is used to fix a plurality of lenses 241, the required length of the moving element 25 is relatively large. If the element 25 is installed in a tube, a plurality of lenses 241 can be better arranged, and the lenses 241 can be better protected in the cavity, so that the lenses 241 are not easily shaken.

In addition, in the example of FIG. 7 , the moving element 25 clamps the plurality of lenses 241 between the two clips 252 , which not only has a certain stability, but also reduces the weight of the moving element 25 and reduces the driving force of the driving mechanism 27 . The power required by the moving element 25 is relatively low, and the design difficulty of the moving element 25 is also relatively low, and the lens 241 is also easier to set on the moving element 25 .

Of course, the moving element 25 is not limited to the above-mentioned cylindrical shape and two clips 252. In other embodiments, the moving element 25 may include three, four or more clips 252 to form a more stable structure. , or a simpler structure such as a clip 252 ; or a rectangular body, a circular body, etc., with a cavity to accommodate various regular or irregular shapes of the lens 241 . On the premise of ensuring the normal imaging and operation of the camera module 10, a specific selection can be made.

The first image sensor 26 may use a complementary metal oxide semiconductor (CMOS, Complementary Metal Oxide Semiconductor) photosensitive element or a charge-coupled device (CCD, Charge-coupled Device) photosensitive element.

In some embodiments, the driving mechanism 27 is an electromagnetic driving mechanism, a piezoelectric driving mechanism or a memory alloy driving mechanism.

Specifically, the electromagnetic drive mechanism includes a magnetic field and a conductor. If the magnetic field moves relative to the conductor, an induced current will be generated in the conductor. The induced current causes the conductor to be affected by the ampere force, and the ampere force causes the conductor to move. The conductor here is an electromagnetic The part of the driving mechanism that drives the moving element 25 to move; the piezoelectric driving mechanism is based on the inverse piezoelectric effect of the piezoelectric ceramic material: if a voltage is applied to the piezoelectric material, mechanical stress will be generated, that is, the conversion between electrical energy and mechanical energy will occur. Controlling its mechanical deformation to generate rotational or linear motion has the advantages of simple structure and low speed.

The drive of the memory alloy drive mechanism is based on the characteristics of the shape memory alloy: the shape memory alloy is a special alloy, once it has memorized any shape, even if it is deformed, when it is heated to a certain appropriate temperature, it can return to The shape before deformation, in order to achieve the purpose of driving, has the characteristics of rapid displacement and free direction.

Please refer to FIG. 6 again, further, the first camera module 20 further includes a driving device 28, and the driving device 28 drives the mounting portion 23 with the light-turning portion 22 to rotate around the rotation axis 29 and move along the axial direction of the rotation axis 29, The rotation axis 29 is perpendicular to the optical axis of the light inlet 211 and the photosensitive direction of the first image sensor 26, so that the first camera module 20 can realize the optical anti-shake on the optical axis of the light inlet 211 and the axis of the rotation axis 29. .

In this way, since the volume of the light converting portion 22 is smaller than that of the lens barrel, the driving device 28 drives the mounting portion 23 to move in two directions, which can not only achieve the optical anti-shake effect of the first camera module 20 in two directions, but also The volume of the first camera module 20 can be made smaller.

Referring to FIGS. 5-6 , for the convenience of description, the width direction of the first camera module 20 is defined as the X direction, the height direction is defined as the Y direction, and the length direction is defined as the Z direction. Therefore, the optical axis of the light inlet 211 is the Y direction, the light receiving direction of the first image sensor 26 is the Z direction, and the axial direction of the rotation axis 29 is the X direction.

The driving device 28 drives the mounting part 23 to rotate, so that the light-transforming part 22 rotates around the X direction, so that the first camera module 20 can achieve the effect of optical anti-shake in the Y direction. In addition, the driving device 28 drives the mounting portion 23 to move along the axial direction of the rotation axis 29 , so that the first camera module 20 can achieve the effect of X-direction optical anti-shake. Additionally, the first lens assembly 24 may be along the Z direction to enable the first lens assembly 24 to focus on the first image sensor 26 .

Specifically, when the light turning part 22 rotates around the X direction, the light reflected by the light turning part 22 moves in the Y direction, so that the first image sensor 26 forms different images in the Y direction to achieve the anti-shake effect in the Y direction. When the light transfer part 22 moves along the X direction, the light reflected by the light transfer part 22 moves in the X direction, so that the first image sensor 26 forms different images in the X direction to realize the anti-shake effect in the X direction.

In some embodiments, the driving device 28 is formed with an arc-shaped guide rail 281 , and the driving device 28 drives the mounting portion 23 to rotate along the arc-shaped guide rail 281 around the central axis 282 of the arc-shaped guide rail 281 and move axially along the central axis 282 , the central axis 2282 coincides with the rotation axis 29 .

In this way, since the driving device 28 uses the arc guide rail 281 to drive the mounting portion 23 with the light turning portion 22 to rotate together, the frictional force between the driving device 28 and the mounting portion 23 is small, which is beneficial to the rotation of the mounting portion 23 It is stable, and the optical anti-shake effect of the first camera module 20 is improved.

Specifically, please refer to FIG. 15 , in the related art, the installation part (not shown) is rotatably connected with the rotating shaft 23a, and the installation part rotates around the rotating shaft 23a to drive the light-turning part 22a to rotate together. It is assumed that the frictional force is f1, the radius of the rotating shaft 23a is R1, the thrust force is F1, and the turning radius is R1. Then the ratio K1 of friction torque and thrust torque is K1=f1R1/F1A1. Since the light-reversing portion 22a only needs to be rotated slightly, F1 cannot be too large; and the camera module itself needs to be light, thin and short, so that the size of the light-reversing portion 22a cannot be too large, and the space for the enlargement of A is also limited, so that the influence of friction cannot be further affected. eliminate.

Referring to FIG. 16 , in the present application, the mounting portion 23 rotates along the arc-shaped guide rail 281 , and the radius of the arc-shaped guide rail 281 is R2 . At this time, the ratio K2 of friction torque and rotational torque is K2=f2R2/F2A. In the case that f2, R2, and F2 do not change significantly, due to the use of orbital oscillation, the corresponding thrust is rotated. The moment becomes R2, and R2 is not limited by the size of the light converting part 22, and can even be several times more than R1. Therefore, in this case, the influence of frictional force on the rotation of the light converting portion 22 can be greatly reduced (the size of K2 is reduced), thereby improving the rotational accuracy of the light converting portion 22 and making the optical anti-shake of the first camera module 20 . The effect is better.

In some embodiments, the mounting portion 23 includes an arc-shaped surface 231 , and the arc-shaped surface 231 is disposed concentrically with the arc-shaped guide rail 281 and cooperates with the arc-shaped guide rail 281 . In other words, the center of the arc-shaped surface 231 coincides with the center of the arc-shaped guide rail 281 . This makes the fitting of the mounting portion 23 and the driving device 28 more compact.

In some embodiments, the central axis 282 is located outside the first camera module 20 . In this way, the radius R2 of the arc-shaped guide rail 281 is relatively large, which can reduce the adverse effect of the frictional force on the rotation of the mounting portion 23 .

In some embodiments, the drive device 28 is located at the bottom of the housing 21 . In other words, the driving device 28 is integrally formed with the casing 21 . In this way, the structure of the first camera module 20 is more compact.

In some embodiments, the driving device 28 drives the mounting portion 23 to rotate electromagnetically. In one example, the driving device 28 is provided with a coil, and the mounting portion 23 is fixed with an electromagnetic sheet. After the coil is energized, the coil can generate a magnetic field to drive the electromagnetic sheet to move, thereby driving the mounting portion 23 and the light turning portion to rotate together.

Of course, in other embodiments, the driving device 28 may drive the mounting portion 23 to move by means of piezoelectric driving or memory alloy driving. For the piezoelectric driving method and the memory alloy driving method, please refer to the above description, which will not be repeated here.

The incident optical axis of the second camera module 30 is the same as the second lens assembly 31. The optical axes of the lens assemblies 31 coincide.

In this embodiment, the second camera module 30 is a fixed-focus lens module. Therefore, the number of lenses 241 of the second lens assembly 31 is less, so that the height of the second camera module 30 is lower, which is beneficial to reduce the size of the electronic device 1000 thickness of.

The type of the second image sensor 32 may be the same as the type of the first image sensor 26 , which will not be repeated here.

The light converting element 50 is an integral molding structure. The light converting element 50 includes a light converting portion 22 and a mounting portion 23 connected to the light converting portion 22 .

The image sensor 26 senses incident light outside the first camera module 20 . The mounting portion 23 can be rotated relative to the housing 21 to adjust the direction in which the light-reversing portion 22 turns the incident light, so that the first camera module 20 can achieve optical anti-shake.
