Referring to fig. 1, an electronic device 1000 according to an embodiment of the present disclosure includes a housing 102 and a camera assembly 100. The camera assembly 100 is disposed on a chassis 102. The electronic device 1000 may be a mobile phone, a tablet computer, a notebook computer, an intelligent bracelet, an intelligent watch, an intelligent helmet, an intelligent glasses, and the like. In the embodiment of the present application, the electronic device 1000 is a mobile phone as an example, and it is understood that the specific form of the electronic device 1000 may be other, and is not limited herein.

Specifically, the housing 102 is an external component of the electronic device 1000, which functions to protect internal components of the electronic device 1000. The housing 102 may be a rear cover of the electronic device 1000, which covers components of the electronic device 1000 such as a battery. In this embodiment, the camera assembly 100 is disposed at the rear, or the camera assembly 100 is disposed at the rear of the electronic device 1000 so that the electronic device 1000 can perform rear-view imaging. As in the example of fig. 1, the camera assembly 100 is disposed at an upper left corner of the housing 102. Of course, it is understood that the camera assembly 100 may be disposed at other locations, such as at the top-middle or top-right position of the housing 102. The position where the camera head assembly 100 is provided in the chassis 102 is not limited to the example of the present application.

Referring to fig. 2 and 3, the camera assembly 100 includes a decoration 10, a first camera module 20, a second camera module 30, and a bracket 40. The decoration 10 is disposed on the housing 102 and protrudes from the surface of the housing 102. The first camera module 20 and the second camera module 30 are both disposed inside the housing 102. The first camera module 20 and the second camera module 30 are both disposed near the decoration 10. First camera module 20 and second camera module 30 all set up in support 40 and with support 40 fixed connection.

The garnish 10 is disposed above the bracket 40, and specifically, the garnish 10 may abut on the bracket 40 or may be disposed spaced apart from the bracket 10. The support 40 can reduce the impact that first camera module 20, second camera module 30 received, improves first camera module 20 and second camera module 30 life-span.

The decoration 10 may be made of a metal material, for example, the decoration 10 may be made of stainless steel, and the decoration 10 may be processed by a polishing process to form a bright surface so that the decoration 10 is more beautiful.

Referring to fig. 4, the through hole 11 is formed in the decoration 10, and the first camera module 20 and the second camera module 30 are exposed out of the decoration 10 from the through hole 11, or the first camera module 20 and the second camera module 30 collect external images through the through hole 11. Specifically, in the present 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 disposed at intervals. Alternatively, the first sub-hole 111 and the second sub-hole 112 are not communicated.

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

In other embodiments, the shapes of the first sub-hole 111 and the second sub-hole 112 are not limited to the shapes illustrated in the drawings. 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 ornament 10 includes an ornament ring 12 and a flange 13, and the flange 13 extends from the bottom of the ornament ring 12 to a direction away from the ornament ring 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 housing 102, and the flange 13 abuts against the housing 102, as shown in fig. 10. In this way, the rim 13 can limit the position of the decoration 10 and prevent the decoration 10 from moving out of the housing 102.

In one example, the garnish 10 is inserted outwardly from the interior of the housing 102 when the garnish 10 is installed, and the garnish 10 is installed at a predetermined position when the collar 13 abuts against the interior surface of the housing 102. The decoration 10 can be fixed on the housing 102 by using an adhesive, or the decoration 10 can be in interference fit with the housing 102, so that the decoration 10 is not easy to fall off from the housing 102.

The decoration 10 may be an integrally formed structure formed by the decoration ring 12 and the convex edge 13, for example, the decoration 10 is manufactured by cutting. In addition, the decorative ring 12 and the flange 13 may be separate structures, or the decorative ring 12 and the flange 13 are formed as two separate elements and then assembled together by welding or the like to form the decoration 10.

It should be noted that in other embodiments, the collar 13 may be omitted, that is, in this embodiment, the decorative piece 10 includes only the configuration of the bezel 12.

The first camera module 20 and the second camera module 30 are arranged in parallel, that is, the second camera module 30 is disposed on one side of the first camera module 20. In the present embodiment, the first camera module 20 and the second camera module 30 are arranged in a straight line, or the first camera module 20 and the second camera module 30 are arranged along the same straight line. In other embodiments, the first and

second camera modules

20 and 30 may be arranged in an L-shape. The first camera module 20 and the second camera module 30 may be disposed at an interval, or may abut against each other.

In this embodiment, the first camera module 20 is located at the right side of the second camera module 30, or the first camera module 20 is closer to the middle of the electronic device 1000 than the second camera module 30. Of course, it is understood that in other embodiments, the positions of the first camera module 20 and the second camera module 30 may 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 may 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 an 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 long-focus camera and the like.

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 fig. 5-7, in the present embodiment, the first camera module 20 includes a housing 21, a light conversion element 50, a first lens assembly 24, a moving element 25, a first image sensor 26, and a driving mechanism 27.

The light conversion element 50, the first lens assembly 24 and the motion element 25 are all disposed in the housing 21. The light conversion element 50 is an integrally formed structure, and the light conversion element 50 includes a light conversion portion 22 and a mounting portion 23 connected to the light conversion portion 22. The first lens assembly 24 is received in the moving element 25. The moving element 25 is disposed on the first image sensor 26 side.

A drive mechanism 27 connects the moving element 25 with the housing 21. After entering the housing 21, the incident light is turned by the light turning part 22 and then reaches the first image sensor 26 through the first lens assembly 24, so that the first image sensor 26 obtains an external image. The driving mechanism 27 drives the moving element 25 to drive the first lens assembly 24 to move, so that the first camera module 20 achieves a focusing effect.

The housing 21 is substantially square, and the housing 21 is provided with a light inlet 211, and the incident light enters the first camera module 20 through the light inlet 211. That is, the light diverting portion 22 is used to divert incident light entering from the light inlet 211 and then transmit the diverted incident light to the first image sensor 26. Therefore, it can be understood that the first camera module 20 is a periscopic lens module, and the height of the periscopic lens module is smaller than that of the vertical lens module, 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 the incident light is transmitted to the photosensitive device of the lens module along the direction of the straight line optical axis.

It can be understood that the light inlet 211 is exposed through the through hole 11, so that 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 the present embodiment, in the width direction of the first camera module 20, a groove 212 is formed on one side of the light inlet 211 of the housing 21, and the decoration 10 is covered on the light inlet 211 and partially inserted into the groove 212.

Referring to fig. 10, if the recess is omitted, in order to make the overall thickness of the electronic device thinner, the periscopic camera module 20a partially extends into the decoration 10a in the width direction, and since the width of the periscopic camera module 20a is larger than that of the vertical camera module, the size of the decoration 10a is larger at this time, which is not good for the appearance of the electronic device, and also makes the electronic device not compact enough.

Referring to fig. 5 and 8 again, in the present embodiment, the groove 212 is formed at one side of the light inlet 211, and the decoration 10 is covered above the light inlet 211 and partially clamped into the groove 212, so that not only the width of the decoration 10 is smaller, but also the overall height of the camera assembly 100 is reduced, which is beneficial to the compact and miniaturized structure of the camera assembly 100.

Specifically, the housing 21 includes a top wall 213 and a side wall 214. The side wall 214 is formed extending from a 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 one of the side walls 2131, or the side walls 214 are respectively connected to two opposite sides of the top wall 213. The light inlet 211 is formed at the top wall 213, the recess 212 is formed at the junction of the top wall 213 and the side wall 214, and the decoration 10 abuts against the top wall 213. In this manner, the groove 212 is easily formed, facilitating the manufacture of the housing 21. In one example, the recess 212 is a profiling of the housing 21, i.e., the recess 212 may be formed by stamping.

In one example, a portion of the bottom of the bezel 12 is received in the recess 212 and a portion of the bezel 12 rests against the top wall 213. Or, the bezel 12 and the housing 21 form a complementary structure, and the bezel 12 and the housing 21 are engaged with each other, so that the fitting structure of the decoration 10 and the housing 21 is more compact.

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

In the present embodiment, the groove 212 has an elongated shape, and the groove 212 extends along the longitudinal direction of the first camera module 20. In this manner, the recess 212 mates more compactly with the trim piece 10. In some embodiments, the groove 212 may be arc-shaped, and the arc-shaped groove 212 surrounds the light inlet 211. Of course, in other embodiments, the structure and shape of the groove 212 are not limited to the above-described example, as long as the decoration 10 and the first camera module 20 form a complementary structure to reduce the size of the decoration 10.

Referring to fig. 6, 7 and 12, the light conversion element 50 is an integrated structure, the light conversion element 50 includes a light conversion portion 22 and a mounting portion 23 connected to the light conversion portion 22, the light conversion portion 22 is used for diverting incident light incident from the light inlet 211 and then transmitting the diverted incident light to the first image sensor 26, so that the first image sensor 26 senses the incident light outside the first camera module 20, and the mounting portion 23 can rotate relative to the housing 21 to adjust a direction in which the light conversion portion 22 diverts the incident light, so that the first camera module 20 realizes optical anti-shake.

In this way, since the light conversion element 50 is integrally formed, the problem that the light conversion part 22 falls off when in use or after falling can be reduced, which is beneficial to improving the reliability of the light conversion 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, a molten material may be injected into the mold and cooled to form the integrally formed light conversion element 50.

Of course, the light conversion element 50 can be made by other methods, and the above examples are only for illustration and do not represent a limitation to the integral molding process.

The light-turning part 22 has a light-reflecting surface 226, and the light-reflecting surface 226 is used for turning and reflecting incident light to the first image sensor 26. In one example, the light-reflecting surface 226 reflects incident light to the first image sensor 26 after rotating the incident light by 90 °. In another example, the light reflecting surface 226 reflects the incident light after rotating 45 ° to the first image sensor 26.

Referring to fig. 12, assuming that the light conversion element 50 is cut in a plane coinciding with the light reflection surface 226, the light conversion element 50 is cut into the light conversion portion 22 and the mounting portion 23 along a dotted line in fig. 12.

A gap 232 is provided between the light reflecting surface 226 and the mounting portion 23. Thus, the gap 232 prevents the light from being refracted to the mounting portion 23 to cause light loss.

Since the light conversion element 50 is an integrally molded structure, the material of the mounting portion 23 is the same as that of the light conversion portion 22, and the mounting portion 23 has a refraction function. The first camera module 20 of the present embodiment uses the difference in refractive index between air and the light converting portion 22 to totally reflect light on the light reflecting surface 226 and prevent the light from entering the mounting portion 23, so the medium in the gap 232 may be air.

Specifically, the voids 232 may be machined into the integrally formed light conversion element 50 using Computer Numerical Control (CNC), laser, or other methods.

The light conversion part 22 may be a prism or a plane mirror. In one example, when the light-converting part 22 is a prism, the prism may be a triangular prism, and the cross section of the prism is, for example, a right triangle, wherein light enters from one of the legs of the right triangle and exits from the other leg after being reflected by the hypotenuse. It will be appreciated that, of course, the incident light may exit after being refracted by the prism, without being reflected. The prism can be made of glass, plastic and other materials with better light transmittance. In one embodiment, one of the surfaces of the prism may be coated with a light reflecting material such as silver to reflect incident light.

It is understood that when the light-converting part 22 is a flat mirror, the flat mirror reflects the incident light to convert the incident light.

Referring to fig. 6 and 12, the light conversion portion 22 has a light incident surface 222, a light reflecting surface 226, and a light emitting surface 228. The light incident surface 22 is close to and faces the light entrance 211, the light reflecting surface 226 is connected to the light incident surface 222, the light emitting surface 228 is connected to the light incident surface 222, and the light reflecting surface 226 is inclined with respect to the light incident surface 222.

Specifically, the light passes through the light inlet 211, enters the light-converting portion 22 through the light-entering surface 222, is reflected by the light-reflecting surface 226, and finally exits the light-converting portion 22 through the light-exiting surface 228, so that the light-converting process is completed.

As shown in fig. 13, in the related art, since the light reflecting surface 226a of the light converting portion 22a is inclined with respect to the horizontal direction and the light converting portion 22a has an asymmetric structure in the light reflecting direction, the incident light cannot be incident on the lower portion of the light reflecting surface 226a because the incident light has a certain incident angle, and thus, the light reflecting surface 226a far from the light inlet is less or cannot reflect the light.

Therefore, referring to fig. 14, the light converter 22 according to the embodiment of the present invention cuts off the corner of the light converter 22a far from the light inlet, which not only does not affect the effect of reflecting light by the light converter 22, but also reduces the overall size of the light converter 22.

In some embodiments, the light-reflecting surface 226 is inclined at an angle α of 45 degrees with respect to the light-entering surface 222.

Therefore, the incident light rays are better reflected and converted, and a better light ray conversion effect is achieved.

The light conversion element 50 may be made of a material having a relatively good light transmittance, such as glass or plastic. In one embodiment, one surface of the light conversion part 22 may be coated with a light reflecting material such as silver to reflect incident light.

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

When the light conversion element 50 is made of glass or the like, the light conversion element 50 itself is brittle, and in order to increase the strength of the light conversion element 50, the light incident surface 222, the light reflecting surface 226, and the light emitting surface 228 of the light conversion part 22 may be hardened.

Furthermore, all surfaces of the light conversion element 50 may be hardened to further enhance the strength of the light conversion element 50. Hardening treatment such as penetration of lithium ions, and film-coating of the above surfaces without affecting the normal operation of the light conversion element 50.

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

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

Referring to fig. 6 again, in an example, the light conversion element 50 is an integrated structure, the light conversion element 50 is movably disposed in the housing 21, and the light conversion element 50 can rotate relative to the housing 21 to adjust a direction in which the light conversion portion 22 converts the incident light.

The light conversion element 50 can rotate together in the direction opposite to the direction of the shake of the first camera module 20, so as to compensate the incident deviation of the incident light at the light inlet 211, thereby achieving the optical anti-shake effect.

The first lens assembly 24 is accommodated in the moving element 25, and further, the first lens assembly 24 is disposed between the light conversion element 50 and the first image sensor 26. The first lens assembly 24 is used to image incident light onto a first image sensor 26. This allows the first image sensor 26 to obtain a better quality image.

The first lens assembly 24 can form an image on the first image sensor 26 when moving integrally along the optical axis thereof, 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 implement the zooming function of the first camera module 20, and more, the driving mechanism 27 drives the moving element 25 to move in the housing 21 to achieve the zooming purpose.

In the example of FIG. 6, in some embodiments, the moving element 25 is cylindrical and the plurality of lenses 241 of the first lens assembly 24 are fixed within the moving element 25 at intervals along the axial direction of the moving element 25. In the example of fig. 7, the moving element 25 includes two clips 252, the two clips 252 sandwiching the lens 241 between the two clips 252.

It can be understood that, because the moving element 25 is used for fixedly arranging the plurality of lenses 241, the length of the moving element 25 is large, and the moving element 25 can be cylindrical or square-cylindrical and has a certain cavity shape, so that the moving element 25 can be in a cylindrical shape to better arrange the plurality of lenses 241, and can better protect the lenses 241 in the cavity, so that the lenses 241 are not easy to shake.

In addition, in the example of fig. 7, the moving element 25 clamps the plurality of lenses 241 between the two clamping pieces 252, which not only has certain stability, but also reduces the weight of the moving element 25, which can reduce the power required by the driving mechanism 27 to drive the moving element 25, and the moving element 25 is also less difficult to design, and the lenses 241 are also easier to be disposed on the moving element 25.

Of course, the moving element 25 is not limited to the above-mentioned cylindrical shape and two clips 252, and in other embodiments, the moving element 25 may include three, four, etc. more clips 252 to form a more stable structure, or one clip 252 to form a simpler structure; or a rectangular body, a circular body, etc. having a cavity for accommodating various regular or irregular shapes of the lens 241. On the premise of ensuring normal imaging and operation of the camera module 10, the specific selection is only needed.

The first image sensor 26 may employ a Complementary Metal Oxide Semiconductor (CMOS) photosensitive element or a Charge-coupled Device (CCD) photosensitive element.

In certain embodiments, the drive mechanism 27 is an electromagnetic drive mechanism, a piezoelectric drive mechanism, or a memory alloy drive mechanism.

Specifically, the electromagnetic driving mechanism includes a magnetic field and a conductor, if the magnetic field moves relative to the conductor, an induced current is generated in the conductor, the induced current makes the conductor subject to an ampere force, and the ampere force makes the conductor move, where the conductor is a part of the electromagnetic 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 voltage is applied to the piezoelectric material, mechanical stress is generated, namely, the electric energy and the mechanical energy are converted, and the rotation or linear motion is generated by controlling the mechanical deformation of the piezoelectric material, so that the piezoelectric material has the advantages of simple structure and low speed.

The driving of the memory alloy driving mechanism is based on the characteristics of the shape memory alloy: the shape memory alloy is a special alloy which, once it has memorized any shape, even if deformed, can recover to the shape before deformation when heated to a certain proper temperature, thereby achieving the purpose of driving, and has the characteristics of rapid displacement and free direction.

Referring to fig. 6 again, the first camera module 20 further includes a driving device 28, the driving device 28 drives the mounting portion 23 with the light rotating portion 22 to rotate around the rotation axis 29 and move along the axial direction of the rotation axis 29, and the rotation axis 29 is perpendicular to the optical axis of the light inlet 211 and the light sensing direction of the first image sensor 26, so that the first camera module 20 achieves optical anti-shake of the optical axis of the light inlet 211 and the axial direction of the rotation axis 29.

In this way, since the size of the light conversion part 22 is smaller than that of the lens barrel, the driving device 28 drives the mounting part 23 to move in two directions, which not only can realize the optical anti-shake effect of the first camera module 20 in two directions, but also can make the size of the first camera module 20 smaller.

Referring to fig. 5-6, for 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. Accordingly, 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 portion 23 to rotate, so that the light rotating portion 22 rotates around the X direction, and the first camera module 20 achieves the Y direction optical anti-shake effect. 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 achieves the effect of optical anti-shake in the X direction. Additionally, the first lens assembly 24 may be along the Z-direction to achieve focusing of the first lens assembly 24 on the first image sensor 26.

Specifically, when the light conversion part 22 rotates around the X direction, the light reflected by the light conversion part 22 moves in the Y direction, so that the first image sensor 26 forms different images in the Y direction to realize the anti-shake effect in the Y direction. When the light conversion part 22 moves along the X direction, the light reflected by the light conversion 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 drive device 28 is formed with an arcuate guide 281, and the drive device 28 drives the mounting portion 23 along the arcuate guide 281 to rotate about a central axis 282 of the arcuate guide 281 and to move axially along the central axis 282, with the central axis 2282 coinciding with the axis of rotation 29.

Thus, since the driving device 28 drives the installation part 23 with the light rotating part 22 to rotate together in the manner of the arc-shaped guide rail 281, the friction force between the driving device 28 and the installation part 23 is small, which is beneficial to the smooth rotation of the installation part 23 and improves the optical anti-shake effect of the first camera module 20.

Specifically, referring to fig. 15, in the related art, a mounting portion (not shown) is rotatably connected to a rotating shaft 23a, and the mounting portion rotates around the rotating shaft 23a to drive the rotating portion 22a to rotate together. Assuming that the friction force is F1, the radius of the rotating shaft 23a is R1, the thrust force is F1, and the rotation radius is R1. The friction torque to thrust torque ratio K1 is then K1 ═ F1R1/F1a 1. Since the light-turning portion 22a only needs to be slightly rotated, F1 cannot be too large; the camera module itself needs to be thin and small, so that the size of the light-turning part 22a cannot be too large, and the enlarged space of a is limited, so that the influence of friction cannot be further eliminated.

Referring to fig. 16, in the present application, the mounting portion 23 rotates along the arc-shaped guide 281, and the radius of the arc-shaped guide 281 is R2. At this time, the ratio K2 between the friction torque and the rotation torque is K2 — F2R2/F2A, and when F2, R2, and F2 do not change greatly, since the orbital oscillation method is adopted for rotation, the corresponding thrust torque becomes R2, and R2 can be not limited by the size of the light conversion part 22, and can be several times or more as large as R1. In this case, the influence of the friction force on the rotation of the light conversion part 22 can be greatly reduced (the size of K2 is reduced), so that the rotation precision of the light conversion part 22 is improved, and the optical anti-shake effect of the first camera module 20 is better.

In some embodiments, the mounting portion 23 includes an arcuate surface 231, the arcuate surface 231 being concentrically disposed with the arcuate guide 281 and cooperating with the arcuate guide 281. Or, the center of the arc-shaped face 231 coincides with the center of the arc-shaped guide 281. This makes the mounting portion 23 more compact to cooperate with the drive means 28.

In some embodiments, the central axis 282 is located outside of the first camera module 20. In this way, the radius R2 of the arcuate guide 281 is larger, which reduces the adverse effect of friction on the rotation of the mounting portion 23.

In some embodiments, the drive means 28 is located at the bottom of the housing 21. Alternatively, the drive means 28 is of unitary construction with the housing 21. Thus, 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 powered on, the coil can generate a magnetic field to drive the electromagnetic sheet to move, so as to drive the mounting portion 23 and the light conversion portion to rotate together.

Of course, in other embodiments, the driving device 28 may drive the mounting portion 23 to move by a piezoelectric driving method or a memory alloy driving method. Please refer to the above description for the piezoelectric driving method and the memory alloy driving method, which are not described herein.

Referring to fig. 9, in the present embodiment, the second camera module 30 is a vertical lens module, but in other embodiments, the second camera module 30 may also be a periscopic lens module. The second camera module 30 includes a second lens assembly 31 and a second image sensor 32, the second lens assembly 31 is used for imaging light on the second image sensor 32, and an incident optical axis of the second camera module 30 coincides with an optical axis of the second lens assembly 31.

In this embodiment, the second camera module 30 is a fixed focus lens module, and therefore, the number of lenses 241 of the second lens assembly 31 is small, so that the height of the second camera module 30 is low, which is beneficial to reducing the thickness of the electronic device 1000.

The type of the second image sensor 32 may be the same as the type of the first image sensor 26 and will not be described in detail herein.

In summary, the first camera module 20 of the present embodiment includes a housing 21 having a light inlet 211, and a light conversion element 50 and a first image sensor 26 both disposed in the housing 21. The light conversion element 50 is an integrally formed structure. The light conversion element 50 includes a light conversion portion 22 and a mounting portion 23 connected to the light conversion portion 22, and the light conversion portion 22 is used for converting incident light incident from the light inlet 211 to be transmitted to the first image sensor 26, so that the first image sensor 26 senses the incident light outside the first camera module 20. The mounting portion 23 can rotate relative to the housing 21 to adjust a direction in which the light converting portion 22 converts incident light, so that the first camera module 20 achieves optical anti-shake.

In the first camera module 20 according to the embodiment of the present application, since the light conversion element 50 is an integrally formed structure, the problem that the light conversion part 22 falls off when in use or after falling can be reduced, which is beneficial to improving the reliability of the light conversion element 50.
