The through hole 11 is formed in the decorative ring 12 and runs through the decorative ring 12 and the convex edge 13 . The decorative ring 12 is installed on the casing 102 , and the convex edge 13 is against the casing 102 , as shown in FIG. 10 . In this way, the protruding edge 13 can limit the position of the decoration part 10 and prevent the decoration part 10 from moving out of the casing 102 .

In one example, when installing the decoration 10 , the decoration 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 decoration 10 is installed to a predetermined position. The decorative part 10 can be fixed on the casing 102 with glue, or the decorative part 10 can be interference-fitted with the casing 102 , so that the decorative part 10 is not easy to fall off from the casing 102 .

The decorative part 10 may be an integrally formed structure formed by the decorative ring 12 and the flange 13 , for example, the decorative part 10 is manufactured by cutting. In addition, the decorative ring 12 and the flange 13 can also be a separate structure, or in other words, the decorative ring 12 and the flange 13 are firstly formed as two independent components, and then assembled together by welding or other processes to form the decorative part 10 .

It should be noted that, in other embodiments, the flange 13 may be omitted, that is to say, in this embodiment, the decoration 10 only includes the structure of the decoration 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, 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 can be arranged at intervals, or they can lean against each other.

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

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

The light turning element 50 , the first lens assembly 24 , and the moving element 25 are all arranged in the housing 21 . The light converting element 50 is integrally formed, and the light converting element 50 includes a light converting part 22 and a mounting part 23 connected with the light converting part 22 . The first lens assembly 24 is accommodated in the moving element 25 . The moving element 25 is provided on the first image sensor 26 side.

The driving mechanism 27 connects the moving element 25 and the casing 21 . After the incident light enters the housing 21 , it is diverted by the light turning 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 achieves the effect of focusing.

The housing 21 is roughly square in shape. The housing 21 is provided with a light inlet 211 , and incident light enters the first camera module 20 through the light inlet 211 . That is to say, the light turning part 22 is used to turn the incident light incident from the light inlet 211 to the first image sensor 26 after turning it. 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 external light enters the first camera module 20 from the light inlet 211 after passing through the through hole 11 .

Please refer to FIG. 8 , in this embodiment, in the width direction of the first camera module 20 , the housing 21 is formed with a groove 212 on one side of the light inlet 211 , and the decorative part 10 is arranged above the light inlet 211 and Partially snap into groove 212 .

Please refer 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 10a in the width direction, because the periscope camera module 20a has the same width as Compared with the width of the vertical camera module, the size of the decorative part 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 decoration 10 is covered above the light inlet 211 and partially snapped into the groove 212, not only Making the width of the decorative part 10 smaller can also reduce the overall height of the camera assembly 100 , which is beneficial to the compact structure and miniaturization of the camera assembly 100 .

Specifically, the housing 21 includes a top wall 213 and a side wall 214 . The side wall 214 extends from the side 2131 of the top wall 213 . The top wall 213 includes two opposite sides 2131, the number of 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 respectively connected to the opposite sides of the top wall 213. sides. The light inlet 211 is formed on the top wall 213 , the groove 212 is formed at the junction of the top wall 213 and the side wall 214 , and the decorative part 10 leans against the top wall 213 . In this way, the groove 212 is easy to form, which is beneficial to the manufacture of the casing 21 . In one example, the groove 212 is a stamped form of the housing 21 , that is, the groove 212 can be formed by stamping.

In one example, part of the bottom of the decorative ring 12 is received in the groove 212 , and a part of the decorative ring 12 abuts against the top wall 213 . In other words, the decorative ring 12 and the shell 21 form a complementary structure, and the decorative ring 12 and the shell 21 are fitted together, so that the matching structure of the decorative part 10 and the shell 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 . In other words, the number of grooves 212 is two. Certainly, in the embodiment, the number of grooves 212 may also be single, that is to say, grooves 212 are formed at the junction of one of the side walls 214 and the top wall 213 .

In this embodiment, the groove 212 is elongated, and the groove 212 extends along the length direction of the first camera module 20 . In this way, the groove 212 fits more compactly with the decoration part 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 implementations, the structure and shape of the groove 212 are not limited to the above examples, 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, Fig. 7 and Fig. 12, the light-transfer element 50 is integrally formed, and the light-transfer element 50 includes a light-transfer part 22 and a mounting part 23 connected with the light-transfer part 22, and the light-transfer part 22 is used to convert the The incident light incident on the optical port 211 is diverted and transmitted 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 part 23 can rotate relative to the housing 21 to adjust the light turning part. 22 to turn the incident light to a direction, so that the first camera module 20 realizes optical anti-shake.

In this way, since the light converting element 50 is integrally formed, the problem of falling off of the light converting part 22 during use or after being dropped can be reduced, which is beneficial to improving the reliability of the light converting element 50 .

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

In another example, the molten material can be injected into the mold, and the integrally molded 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 example is only for explanation, and does not represent a limitation on the integrally formed process.

The light turning part 22 has a reflective surface 226 for turning and reflecting 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 , assuming that the light converting element 50 is cut on a plane coincident with the reflective surface 226 , the light converting element 50 is cut along the dotted line in FIG. 12 into the light converting portion 22 and the mounting portion 23 .

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 installation portion 23 to cause light loss.

Since the light converting element 50 is integrally formed, the material of the mounting part 23 is consistent with that of the light converting part 22 , and the mounting part 23 has the function of refraction. The first camera module 20 of this embodiment makes use of the refractive index difference between the light in the air and the light transfer part 22, so that the light is totally reflected on the reflective surface 226 and cannot enter the installation part 23. Therefore, the medium in the gap 232 can be Air.

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

The light converting part 22 can be a prism or a plane mirror. In one example, when the light conversion part 22 is a prism, the prism can be a triangular prism, and the cross section of the prism is, for example, a right triangle, wherein the light is incident from one of the right angle sides in the right triangle, and after being reflected by the hypotenuse, another A right-angled edge emerges. It can be understood that, of course, the incident light can be refracted by the prism and then exit without reflection. The prism can be made of materials with better light transmission properties such as glass and plastic. In one embodiment, one of the surfaces 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 diverting part 22 is a plane mirror, the plane mirror reflects the incident light so as to achieve redirection of the incident light.

More, please refer to FIG. 6 and FIG. 12 , the light transfer portion 22 has a light incident surface 222 , a light reflection surface 226 , and a light output surface 228 . The light incident surface 22 is close to and faces the light entrance 211 , the light reflective surface 226 is connected to the light incident surface 222 , the light exit surface 228 is connected to the light incident surface 222 , and the light reflective surface 226 is inclined relative 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 light reflecting surface 226 , and finally exits the light turning portion 22 from the light emitting surface 228 , and the light thus completes the turning process.

As shown in Figure 13, in the related art, due to the need to reflect the incident light, the reflective surface 226a of the light conversion part 22a is inclined relative to the horizontal direction, and the light conversion part 22a is an asymmetric structure in the reflection direction of the light. The light has a certain incident angle, therefore, the incident light cannot enter the lower part of the reflective surface 226a, therefore, the part of the reflective surface 226a away from the light inlet is less or unable to reflect light.

Therefore, referring to FIG. 14 , the light turning part 22 in the embodiment of the present application cuts away the corners away from the light entrance compared to the light turning part 22a in the related art, so that not only does not affect the effect of the reflected light of the light turning part 22, but also The overall size of the light turning part 22 is reduced.

In some embodiments, the angle α of the reflective 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 glass, plastic and other materials with relatively good light transmission. In one embodiment, a reflective material such as silver may be coated on one surface of the light transfer portion 22 to reflect incident light.

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

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

Furthermore, all surfaces of the light-transferring element 50 can be hardened to further increase the strength of the light-transferring element 50 . Hardening treatment, such as infiltrating lithium ions, applying films to the above surfaces without affecting the normal operation of the light converting element 50 , etc.

In one example, the angle at 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 reflective 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 diverting unit 22 diverts the incident light may also be other angles, such as 80 degrees, 100 degrees, etc., as long as the incident light can be diverted and reach the first image sensor 26 .

In this embodiment, the number of the light turning element 50 is one, and at this time, the incident light passes to the first image sensor 26 after being turned once. In other embodiments, there are multiple light turning elements 50 , at this time, 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 turning element 50 is integrally formed. The light turning element 50 is movably arranged in the housing 21. The light turning element 50 can rotate relative to the housing 21 to adjust the light turning part 22. The direction to turn the incoming light.

The light turning element 50 can rotate together towards the opposite direction of the shaking of the first camera module 20, so as to compensate the incident deviation of the incident light at the light inlet 211, and realize the effect of optical anti-shaking.

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

The first lens assembly 24 can form an image on the first image sensor 26 when it moves as a whole along its optical axis, so as to achieve 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, thereby realizing the zoom function of the first camera module 20. More, it is driven by the drive mechanism 27 The moving element 25 moves in the housing 21 for zooming purposes.

In the example of FIG. 6 , in some embodiments, the moving element 25 is cylindrical, and a plurality of lenses 241 in the first lens assembly 24 are fixed in 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 between which the lens 241 is sandwiched.

It can be understood that since the moving element 25 is used to fix a plurality of lenses 241, the length of the required moving element 25 is relatively large, and the moving element 25 can be cylindrical, square, etc., with a relatively certain cavity shape, so that the moving element 25 can move The element 25 is packaged in a tube so that 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 less likely to shake.

In addition, in the example of FIG. 7 , the moving element 25 clamps a plurality of lenses 241 between two clips 252, which not only has a certain degree of stability, but also reduces the weight of the moving element 25, and can reduce the driving force of the driving mechanism 27. The power required by the moving element 25 is lower, and the design difficulty of the moving element 25 is relatively low, and the lens 241 is also easier to be arranged 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 cavities 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 , specific selections 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 will cause the conductor to be affected by the Ampere force, and the Ampere force will make the conductor move. The conductor here is 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 is generated, that is, conversion between electrical energy and mechanical energy occurs, through Controlling its mechanical deformation to generate rotation or linear motion has the advantages of simple structure and low speed.

The driving mechanism of the memory alloy driving mechanism is based on the characteristics of the shape memory alloy: the shape memory alloy is a special alloy. The shape before deformation is used to achieve the purpose of driving, and it 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 part 23 with the light turning part 22 to rotate around the rotation axis 29 and move axially along 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 realizes the optical anti-shake in the axial direction of the optical axis of the light inlet 211 and the rotation axis 29 .

In this way, since the volume of the light transfer 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 The volume of the first camera module 20 can be made smaller.

Please refer to FIGS. 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. Thus, the optical axis of the light inlet 211 is in the Y direction, the photosensitive direction of the first image sensor 26 is in the Z direction, and the axial direction of the rotation axis 29 is in the X direction.

The driving device 28 drives the installation part 23 to rotate, so that the light turning part 22 rotates around the X direction, so that the first camera module 20 realizes the effect of optical anti-shake in the Y direction. In addition, the driving device 28 drives the installation part 23 to move axially along the rotation axis 29 , so that the first camera module 20 realizes the effect of optical anti-shake in the X direction. In addition, the first lens assembly 24 can 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 turning part 22 moves along the X direction, the light reflected by the light turning 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 part 23 to rotate along the arc-shaped guide rail 281 around the central axis 282 of the arc-shaped guide rail 281 and to move axially along the central axis 282 , the central axis 2282 coincides with the rotational axis 29 .

In this way, since the driving device 28 uses the arc-shaped guide rail 281 to drive the mounting part 23 with the light turning part 22 to rotate together, the friction force between the driving device 28 and the mounting part 23 is small, which is conducive to the rotation of the mounting part 23 Stable, improving the optical anti-shake effect of the first camera module 20.

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

Please refer to FIG. 16 , and in this application, the installation part 23 rotates along the arc guide rail 281 , and the radius of the arc guide rail 281 is R2. At this time, the ratio K2 of the frictional torque to the rotational torque is K2=f2R2/F2A. When f2, R2, and F2 do not change significantly, the corresponding thrust rotation The moment becomes R2, and R2 is not limited by the size of the light-transferring part 22, and may even be several times more than R1. Therefore, in this case, the influence of frictional force on the rotation of the light turning part 22 can be greatly reduced (the size of K2 is reduced), thereby improving the rotation accuracy of the light turning part 22 and making the optical anti-shake of the first camera module 20 The effect is better.

In some embodiments, the installation part 23 includes an arc surface 231 , and the arc surface 231 is arranged concentrically with the arc guide rail 281 and cooperates with the arc guide rail 281 . In other words, the center of the arc surface 231 coincides with the center of the arc guide rail 281 . In this way, the mounting part 23 and the driving device 28 can be matched more compactly.

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 friction on the rotation of the installation part 23 .

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

In some embodiments, the driving device 28 drives the mounting part 23 to rotate in an electromagnetic manner. In one example, the driving device 28 is provided with a coil, and the electromagnetic sheet is fixed on the installation part 23. After the coil is energized, the coil can generate a magnetic field to drive the electromagnetic sheet to move, thereby driving the installation part 23 and the optical conversion part to rotate together.

Certainly, in other implementation manners, the driving device 28 may drive the installation part 23 to move by means of piezoelectric driving or memory alloy driving. Please refer to the above description for the piezoelectric driving method and memory alloy driving method, and will not repeat them here.

Please refer to FIG. 9 , in this embodiment, the second camera module 30 is a vertical lens module, of course, in other embodiments, the second camera module 30 may also be a periscope 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 to image the light on the second image sensor 32, the incident optical axis of the second camera module 30 is in line with the second 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 lenses 241 of the second lens assembly 31 are 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.

To sum up, the first camera module 20 according to the embodiment of the present application includes the housing 21 with the light inlet 211 opened therein, and the light-transfer element 50 and the first image sensor 26 both disposed in the housing 21 . The light turning element 50 is integrally formed. The light turning element 50 includes a light turning part 22 and a mounting part 23 connected to the light turning part 22. The light turning part 22 is used to turn the incident light incident from the light inlet 211 to the first image sensor 26 so that the first The image sensor 26 senses incident light outside the first camera module 20 . The mounting part 23 can be rotated relative to the housing 21 to adjust the direction in which the light turning part 22 turns the incident light, so that the first camera module 20 realizes optical anti-shake.

In the first camera module 20 of the embodiment of the present application, since the light converting element 50 is integrally formed, the problem of falling off of the light converting part 22 during use or falling can be reduced, which is beneficial to improve the reliability of the light converting element 50 .
