Referring to fig. 1, an electronic device 1000 according to an embodiment of the invention 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. The embodiment of the invention is described by taking the electronic device 1000 as 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 assembly 100 is provided in the chassis 102 is not limited to the example of the present invention.

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 prism 22, a mounting base 23, a first lens assembly 24, a moving element 25, a driving mechanism 27, and a first image sensor 26. The prism 22, the mount 23, the first lens assembly 24, and the moving element 25 are all disposed within the housing 21. The prism 22 is disposed on the mounting base 23, the first lens unit 24 is accommodated in the moving member 25, and the driving mechanism 27 connects the moving member 25 and the housing 21. After entering the housing 21, the incident light is deflected by the prism 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 move the first lens assembly 24, so that the first camera module 20 achieves a zooming effect.

As shown in fig. 6, in some embodiments, the moving element 25 has a cylindrical shape, and a plurality of lenses 241 are fixed in the moving element 25 at intervals along the axial direction of the moving element 25; or as shown in fig. 7, the moving element 25 includes two clips 252, and the two clips 252 clamp the plurality of lenses 241.

It can be understood that, because the moving element 25 is used for fixedly arranging the lenses 241 arranged at a plurality of intervals, 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 is in a cylindrical shape and can be better provided with a plurality of lenses 241, and the lenses 241 can be better protected in the cavity, so that the lenses 241 are not easy to shake.

In addition, the moving element 25 has certain stability because the two clamping pieces 252 clamp the plurality of lenses 241 between the two clamping pieces 252, the weight of the moving element 25 can be reduced, the power required by the driving mechanism 27 to drive the moving element 25 can be reduced, the design difficulty of the moving element 25 is low, and the lenses 241 are easily 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, 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 imaging module 10, the specific selection is only needed.

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 prism 22 is used to divert incident light incident from the light inlet 211 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.

In one example, the prism 22 is a triangular prism and the cross-section of the prism 22 is a right triangle, wherein light is incident from one of the legs of the right triangle and exits through reflection from the hypotenuse to the other leg. It will be appreciated that, of course, the incident light may exit after being refracted by the prism 22, without being reflected. The prism 22 may be made of a material having a relatively high light transmittance, such as glass or plastic. In one embodiment, one of the surfaces of the prism 22 may be coated with a light reflecting material such as silver to reflect incident light.

Referring to fig. 12 and 13, the prism 22 includes an edge 222, and the edge 222 is chamfered or rounded. It will be appreciated that the prism 22 includes a right-angle surface and an acute-angle surface, wherein the edge 222 forms an edge portion of the prism 22, which is easily damaged by external impact, so that the edge 222 is chamfered or rounded to form a smoother and smoother structure at each edge 222 of the prism 22, thereby reducing damage to the prism 22 when the impact is applied.

In one example, all the edges 222 of the prism 22 are rounded to form a rounded structure on all the edge portions of the prism 22, so as to improve the strength of the prism 22 as a whole;

in another example, all of the edges 222 of the prism 22 are chamfered so that all edge portions of the prism 22 form a chamfered structure to enhance the strength of the prism 22 as a whole.

In some examples, a portion of the edge 222 of the prism 22 is chamfered and a portion of the edge 222 is rounded.

In some examples, the three shorter edges 222 of the prism 22 may be chamfered or rounded to reduce the cost and duration of the process. Of course, one or more of the edges 222 of the prism 22 may be optionally chamfered or rounded to accommodate further embodiments.

In one example, the prism 22 turns the incident light incident from the light inlet 211 at an angle of 90 degrees. For example, the incident angle of the incident light on the emitting surface of the prism 22 is 45 degrees, and the reflection angle is also 45 degrees. Of course, the angle at which the prism 22 turns the incident light may be other angles, such as 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 prisms 22 is one, and in this case, the incident light is once turned and then transmitted to the first image sensor 26. In other embodiments, the number of prisms 22 is multiple, and the incident light is diverted to the first image sensor 26 at least twice.

In some embodiments, the radius of the rounded edge of edge 222 is 0.1-0.15mm, or the size of the chamfer of edge 222 is 0.1-0.15 mm.

The radius range of the rounded corner of the edge 222 is appropriate to the size of the chamfered corner of the edge 222, so that the integral structure of the prism 22 can be ensured to be relatively complete, the strength of the prism 22 can be ensured, and the implementation is relatively easy. Of course, the radius of the fillet and the size of the chamfer are not limited to the above-mentioned ranges, and may be selected specifically in specific embodiments.

The chamfer dimension of the edge 222 of 0.1-0.15mm means: the size of any one chamfer straight edge of the chamfer is 0.1-0.15mm, and the size of the chamfer straight edge is 0.1mm, 0.11mm, 0.12mm and the like.

The rounded corners of the edges 222 have a radius of, for example, 0.1mm, 0.11mm, 0.12mm, etc.

In some embodiments, the outer surface 226 of the prism 22 is hardened and formed with a hardened layer.

The prism 22 itself is brittle, and in order to increase the strength of the prism 22, the outer surface 226 of the prism 22 may be hardened, for example, by penetrating lithium ions, or by attaching a film to the outer surface 226 without affecting the light conversion of the prism 22.

The mounting seat 23 is used for mounting the prism 22, or the mounting seat 23 is a carrier of the prism 22, and the prism 22 is fixedly arranged on the mounting seat 23. This allows the position of the prism 22 to be determined to facilitate the prism 22 to reflect or refract incident light. The prism 22 can be fixed on the mounting seat 23 by using an adhesive bonding to realize a fixed connection with the mounting seat 23.

Referring to fig. 6, in one example, the mounting seat 23 is movably disposed in the housing 21, the mounting seat 23 can rotate relative to the rotation axis 232 of the housing 21 to adjust the direction of the incident light of the prism 22, and the size of the chamfer or the fillet formed by the edge 224 consistent with the extending direction of the rotation axis 232 is larger than that of the chamfer or the fillet formed by the other edges 222. In this way, the prism 22 can be rotated to prevent the edge 224 from interfering with other components of the first imaging module 20.

The mounting seat 23 can drive the prism 22 to rotate together in the direction opposite to the shaking direction of the first camera module 20, so as to compensate the incident deviation of the incident light of the light inlet 211, and achieve the optical anti-shaking effect. The mounting seat 23 may be connected to a driving mechanism 27, and the driving mechanism 27 may drive the mounting seat 23 to rotate. Furthermore, the edge 224 coinciding with the extending direction of the rotation axis 232 may mean that the extending direction of the edge 224 and the extending direction of the rotation axis 232 may be parallel to each other or slightly inclined to each other.

The first lens assembly 24 is accommodated in the moving element 25, and further, the first lens assembly 24 is disposed between the prism 22 and the first image sensor 26. The first lens assembly 24 is used to image incident light onto the 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 function of zooming of the first camera module 20, and further, the driving mechanism 27 drives the moving element 25 to move in the housing 21 for zooming.

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 12 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.
