Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

Referring to fig. 1, an electronic device 1000 according to an embodiment of the present disclosure includes a housing 110 and a camera assembly 100. The camera assembly 100 is exposed through the housing 110.

By way of example, the electronic device 1000 may be any of various types of computer system equipment (only one modality shown in fig. 1 by way of example) that is mobile or portable and that performs wireless communications.

Specifically, the electronic apparatus 1000 may be a mobile phone or a smart phone (e.g., an iPhone system (apple) based phone, an Android system (Android) based phone), a portable game device (e.g., an iPhone (apple phone)), a laptop, a Palmtop (PDA), a portable internet appliance, a music player, and a data storage device, other handheld devices, and devices such as a watch, an in-ear headset, a pendant, a headset, and the like.

The electronic apparatus 100 may also be other wearable devices (e.g., head mounted di spot, HMD), such as electronic glasses, electronic clothing, electronic bracelets, electronic necklaces, electronic tattoos, electronic devices, or smartwatches).

The housing 110 is an external component of the electronic device 1000, and plays a role of protecting internal components of the electronic device 1000. The housing 110 may be a rear cover of the electronic device 1000, and the rear cover covers parts 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-middle position of the cabinet 110.

Of course, it is understood that the camera assembly 100 may be disposed at other positions such as an upper left position or an upper right position of the housing 110. The position where the camera head assembly 100 is provided in the cabinet 110 is not limited to the examples of the present application.

Referring to fig. 2, the camera assembly 100 includes a first imaging module 20, a second imaging module 30, a third imaging module 40, and a bracket 50.

The first imaging module 20, the second imaging module 30 and the third imaging module 40 are all disposed in the bracket 50 and are fixedly connected with the bracket 50. The bracket 50 can reduce the impact on the first imaging module 20, the second imaging module 30 and the third imaging module 40, and improve the service life of the first imaging module 20, the second imaging module 30 and the third imaging module 40.

In the present embodiment, the field angle FOV3 of the third imaging module 40 is larger than the field angle FOV1 of the first imaging module 20 and smaller than the field angle FOV2 of the second imaging module 30, that is, FOV1 < FOV3 < FOV 2. Thus, the three imaging modules with different field angles enable the camera assembly 100 to meet the shooting requirements in different scenes.

In one example, the field angle FOV1 of the first imaging module 20 is 10-30 degrees, the field angle FOV2 of the second imaging module 30 is 110-130 degrees, and the field angle FOV3 of the third imaging module 40 is 80-110 degrees.

For example, the field angle FOV1 of the first imaging module 20 is 10 degrees, 12 degrees, 15 degrees, 20 degrees, 26 degrees, or 30 degrees. The field angle FOV2 of the second imaging module 30 is 110, 112, 118, 120, 125 or 130 degrees. The FOV3 of the third imaging module 40 is 80, 85, 90, 100, 105 or 110 degrees.

Since the field angle FOV1 of the first imaging module 20 is small, it can be understood that the focal length of the first imaging module 20 is large, and therefore, the first imaging module 20 can be used to capture a long shot, thereby obtaining a sharp long shot image. The field angle FOV2 of the second imaging module 30 is larger, and it can be understood that the focal length of the second imaging module 30 is shorter, so the second imaging module 30 can be used to capture a close-up view, thereby obtaining a close-up image of a part of an object. The third imaging module 40 can be used for normally photographing the object.

In this way, by combining the first imaging module 20, the second imaging module 30 and the third imaging module 40, image effects such as background blurring and local sharpening of images can be obtained.

The second imaging module 30 is disposed proximate to the first imaging module 20. The third imaging module 40 is disposed adjacent to the second imaging module 30. The second imaging module 30 is disposed between the first imaging module 20 and the third imaging module 40.

The first imaging module 20, the second imaging module 30 and the third imaging module 40 are arranged in parallel. In the present embodiment, the first imaging module 20, the second imaging module 30 and the third imaging module 40 are arranged in an L shape.

Due to the field angle of the first imaging module 20 and the third imaging module 40, in order to obtain images with better quality from the first imaging module 20 and the third imaging module 40, the first imaging module 20 and the third imaging module 40 may be configured with an optical anti-shake device, and the optical anti-shake device is generally configured with more magnetic elements, so that the first imaging module 20 and the third imaging module 40 can generate a magnetic field.

In the present embodiment, the second imaging module 30 is located between the first imaging module 20 and the third imaging module 40, so that the first imaging module 20 and the third imaging module 40 can be far away from each other, and the magnetic field formed by the first imaging module 20 and the magnetic field formed by the third imaging module 40 are prevented from interfering with each other and affecting the normal use of the first imaging module 20 and the third imaging module 40.

The arrangement of the first imaging module 20, the second imaging module 30 and the third imaging module 40 in the L shape may mean that a first plane formed by the imaging optical axis and the light inlet axis of the first imaging module 20 is substantially perpendicular to a second plane formed by the light inlet axis of the second imaging module 30 and the light inlet axis of the third imaging module 40; it can also mean that the connecting lines of the central points of the light inlets of the first imaging module 20, the second imaging module 30 and the third imaging module 40 are in an "L" shape.

In other embodiments, the first imaging module 20, the second imaging module 30, and the third imaging module 40 are arranged along the same line.

The first imaging module 20, the second imaging module 30 and the third imaging module 40 are arranged along the same straight line, which means that a first plane formed by the imaging optical axis and the light inlet axis of the first imaging module 20 and a second plane formed by the light inlet axis of the second imaging module 30 and the light inlet axis of the third imaging module 40 are coplanar.

The first imaging module 20, the second imaging module 30 and the third imaging module 40 may be disposed at intervals, and two adjacent imaging modules may abut against each other.

In the first imaging module 20, the second imaging module 30, and the third imaging module 40, any one of the imaging modules may be a black-and-white camera, an RGB camera, or an infrared camera.

It is to be noted that the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 3-5, in the present embodiment, the first imaging module 20 includes a light conversion device 10, a housing 21, a first lens assembly 24, a loading element 25, a first image sensor 26, a driving mechanism 27, and a driving device 28.

The first lens assembly 24 and the loading element 25 are disposed in the housing 21. The first lens assembly 24 is secured to the mounting member 25. The loading member 25 is disposed at a side of the first image sensor 26. Further, the loading element 25 is located between the light conversion device 10 and the first image sensor 26.

A drive mechanism 27 connects the loading element 25 with the housing 21. After entering the first imaging module 20, the incident light is turned by the light turning device 10 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 is used for driving the loading element 25 to move along the optical axis of the first lens assembly 24 so as to focus and image the first lens assembly 24 on the first image sensor 26.

Referring to fig. 6 and 7, in the present embodiment, the light conversion device 10 includes a lens barrel 11, a light conversion element 12, and a two-axis hinge 13. The light conversion element 12 is disposed inside the lens barrel 11. The light conversion element 12 is used for converting light rays from the light inlet axis 101 to the imaging optical axis 102, and the imaging optical axis 102 is perpendicular to the light inlet axis 101. The biaxial hinge 13 rotatably connects the lens barrel 11 and the light conversion element 12. The two-axis hinge 13 includes a first rotation axis 103 and a second rotation axis 104, the first rotation axis 103 is perpendicular to the light entering axis 101 and the imaging optical axis 102, and the second rotation axis 104 is parallel to the light entering axis 101.

In this way, the first rotating shaft 103 and the second rotating shaft 104 of the two-axis hinge 13 can enable the light conversion element 12 to rotate in two directions, and the rotation precision of the light conversion element 12 is high, so that the camera with the light conversion device 10 can achieve a good optical anti-shake effect in two directions. In addition, the two-axis hinge 13 is compact, and the volume of the light conversion device 10 can be reduced.

It should be noted that the light entering from the light entrance axis 101 refers to the light entering into the first imaging module 20 with the light entrance axis 101 as the center, and the light may be parallel to the light entrance axis 101 or may form a certain angle with the light entrance axis 101.

In addition, the light rays that turn toward the imaging optical axis 102 refer to light rays that propagate around the imaging optical axis 102, and the light rays may be parallel to the imaging optical axis 102 or may form a certain angle with the imaging optical axis 102.

It is understood that the first imaging module 20 is a periscopic camera module. Compare in vertical lens module, the height of periscopic camera module is less to can reduce electronic device 1000's whole thickness. The vertical lens module means that the imaging optical axis and the light inlet axis of the lens module are a straight line. In other words, the incident light is transmitted to the photosensitive device of the lens module along a linear optical axis.

Specifically, the lens barrel 11 is substantially square. The lens barrel 11 may be made of plastic, metal, or the like. The lens barrel 11 has a light inlet 211, and the incident light enters the light conversion device 10 through the light inlet 211. That is, the light diverting element 12 is used for diverting the incident light entering from the light inlet 211 and passing the diverted incident light to the first image sensor 26 through the first lens assembly 24 so that the first image sensor 26 senses the incident light outside the first imaging module 20.

Referring to fig. 4 and 6, the lens barrel 11 includes a top wall 213, a side wall 214, and a bottom wall 216. The side wall 214 is formed extending from a side edge 2131 of the top wall 213. The bottom wall 216 is opposite the top wall 213. The top wall 213 is formed with a light inlet 211, or the light inlet 211 is formed in the top wall 213. The top wall 213 includes two opposing sides 2131. The number of sidewalls 214 is two, and each sidewall 214 extends from a corresponding one of the side edges 2131. Alternatively, the sidewalls 214 are connected to opposite sides of the top wall 213.

The light conversion element 12 includes a prism 22 and a mount 23, and the prism 22 is disposed on the mount 23. 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.

The prism 22 may be a triangular prism having a right triangle cross-section, wherein light is incident from one of the right-angled faces of the right triangle and then reflected to exit from the other right-angled face.

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.

Referring to fig. 6 and 8, the prism 22 has a light incident surface 222, a light emergent surface 224, a light rotating surface 226, a light emergent surface 228, and a side surface 229. The light incident surface 222 is close to and faces the light inlet 211. The backlight surface 224 is far away from the light inlet 211 and is opposite to the light incident surface 222. The backlight surface 224 is formed by a missing corner structure formed on the side of the prism 22 remote from the light-in surface 222. Alternatively, the prism 22 has a missing corner structure on a side away from the light incident surface 222 and forms a backlight surface 224.

The light-turning surface 226 connects the light-incident surface 222 and the light-exiting surface 224. The light-emitting surface 228 connects the light-entering surface 222 and the light-exiting surface 224. The side surface 229 is connected to the light incident surface 222 and the light emitting surface 228. The light exit surface 228 faces the first image sensor 26. The light-turning surface 226 is disposed obliquely to the light-entering surface 222. The light emitting surface 228 is opposite to the light rotating surface 226.

Specifically, in the turning process of the light, the light passes through the light inlet 211 and enters the prism 22 through the light incident surface 222, and finally is reflected out of the prism 22 from the light emitting surface 228, thereby completing the turning process of the light. In other words, the prism 22 is used to divert the light incident from the light incident surface 222 and then emit the light from the light emitting surface 228. The backlight surface 224 is fixedly arranged with the mounting seat 23 to keep the prism 22 stable.

As shown in fig. 9, in the related art, the light-turning surface 226a of the prism 22a is inclined with respect to the horizontal direction due to the need to reflect the incident light, and the prism 22a has an asymmetric structure in the reflection direction of the light. Thus, the actual optical area below the prism 22a is small relative to the actual optical area above the prism 22 a. This is understood to mean that the portion of the light-diverting surface 226a away from the light inlet is less or unable to reflect light.

Therefore, referring to fig. 10, the prism 22 of the embodiment of the present application cuts off the corner angle far from the light inlet with respect to the prism 22a in the related art, which not only does not affect the effect of the prism 22 on reflecting light, but also reduces the overall thickness of the prism 22.

Referring to fig. 6 again, the light-converting surface 226 is inclined at an angle α of 45 degrees with respect to the light-incident surface 222. Therefore, the incident light rays are better reflected and converted, and a better light ray conversion effect is achieved.

Further, 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. Of course, the prism 22 can use the principle of total reflection of light to achieve the incident light turning. In this case, the prism 22 does not need to be coated with a reflective material.

As in the example of fig. 6, the light incident surface 222 and the light exit surface 224 are arranged in parallel. Thus, when the backlight surface 224 and the mounting base 23 are fixedly arranged, the prism 22 can be kept stable, the light incident surface 222 is also a plane, and incident light forms a regular light path in the conversion process of the prism 22, so that the conversion efficiency of the light is better.

Specifically, along the light incident direction of the light inlet 211, the cross section of the prism 22 is substantially trapezoidal, or the prism 22 is substantially trapezoidal. As in the example of fig. 6, the light-in surface 222 and the light-out surface 224 are both perpendicular to the light-out surface 228. Thus, a regular prism 22 can be formed, so that the light path of the incident light is straight, and the conversion efficiency of the light is improved.

In one example, the distance between the light-in surface 222 and the light-out surface 224 is in the range of 4.8-5.0 mm. For example, the distance between the light incident surface 222 and the light backlight surface 224 may be 4.85mm, 4.9mm, 4.95mm, and the like. Alternatively, the distance between the light incident surface 222 and the light emergent surface 224 is understood to be 4.8-5.0 mm.

The prism 22 formed by the light incident surface 222 and the light backlight surface 224 in the above distance range has a moderate volume, and can be better integrated into the first imaging module 20, so as to form a more compact and miniaturized first imaging module 20, camera assembly 100 and electronic device 1000, thereby satisfying more demands of consumers.

Optionally, the light incident surface 222, the light backlight surface 224, the light conversion surface 226, the light emitting surface 228, and the side surface 229 are hardened to form a hardened layer.

When the prism 22 is made of glass or the like, the prism 22 itself is brittle, and in order to increase the strength of the prism 22, the light incident surface 222, the backlight surface 224, the light conversion surface 226, and the light emitting surface 228 of the prism 22 may be hardened. Furthermore, all surfaces of the light conversion element 12 may be hardened to further increase the strength of the light conversion element 12.

Further, the hardening treatment may be infiltration of lithium ions, or coating of the above surfaces without affecting the conversion of light by the prism 22, or the like.

In one example, the prism 22 turns the incident light incident from the light inlet 211 at an angle of 90 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.

The mounting base 23 is used for mounting the prism 22, or the mounting base 23 is a carrier of the prism 22. The prism 22 is fixed to the mount 23. This allows the position of the prism 22 to be determined to facilitate the prism 22 to reflect or refract incident light.

Specifically, referring to fig. 4, in the present embodiment, the mounting base 23 is provided with a position-limiting structure 232, and the position-limiting structure 232 is connected to the prism 22 to limit the position of the prism 22 on the mounting base 23.

In this way, the position limiting structure 232 limits the position of the prism 22 on the mounting seat 23, so that the prism 22 does not shift under the condition of impact, and normal use of the first imaging module 20 is facilitated.

It is understood that in one example, the prism 22 is fixed on the mounting seat 23 by adhesion, and if the position limiting structure 232 is omitted, the prism 22 is easy to fall off from the mounting seat 23 if the adhesion force between the prism 22 and the mounting seat 23 is insufficient when the first imaging module 20 is impacted.

In the present embodiment, the mounting seat 23 is formed with a receiving groove 233, the prism 22 is disposed in the receiving groove 233, and the limiting structure 232 is disposed at an edge of the receiving groove 233 and abuts against the prism 22.

Thus, the accommodating groove 233 allows the prism 22 to be easily mounted on the mounting seat 23. The position limiting structure 232 is disposed at the edge of the accommodating groove 233 and abuts against the edge of the prism 22, so that the position of the prism 22 can be limited, and the prism 22 is not prevented from emitting the incident light to the first image sensor 26.

Further, the position-limiting structure 232 includes a protrusion 234 protruding from the edge of the receiving groove 233, and the protrusion 234 abuts against the edge of the light-emitting surface 228.

Since the prism 22 is mounted on the mounting base 23 through the light-rotating surface 226, the light-emitting surface 228 is disposed opposite to the light-rotating surface 226. Therefore, the prism 22 is more likely to be positioned toward the light exit surface 228 when being impacted. In the present embodiment, the position-limiting structure 232 abuts against the edge of the light-emitting surface 228, so that the prism 22 is prevented from moving to the side of the light-emitting surface 228, and the light can be ensured to be emitted from the light-emitting surface 228 normally.

Of course, in other embodiments, the position limiting structure 232 may include other structures as long as the position of the prism 22 can be limited. For example, the position limiting structure 232 is formed with a slot, the prism 22 is formed with a position limiting post, and the position limiting post is clamped in the slot to limit the position of the prism 22.

In the present embodiment, the protrusion 234 is in a shape of a strip and extends along the edge of the light emitting surface 228. Thus, the contact area between the protrusion 234 and the edge of the light emitting surface 228 is large, so that the prism 22 can be more stably located in the mounting seat 23.

Of course, in other embodiments, the protrusion 234 may have other structures such as a block shape.

It can be understood that the mounting seat 23 can drive the prism 22 to rotate together in the opposite direction to the shake of the first imaging module 20, so as to compensate the incident deviation of the incident light of the light inlet 211, and achieve the optical anti-shake effect.

Referring to fig. 11, in the related art, the light-converting surface of the prism 22b generally faces the mounting base, and when the light reflected by the mounting base enters the prism 22b from a certain angle, the incident light can be refracted by the light-converting surface 226b of the prism 22b and then exit from the light-entering surface 222b, so that the appearance of the periscopic camera can be reduced by seeing the abnormal phenomenon through the light-entering surface 222 b.

In this embodiment, referring to fig. 6 and 8, the mounting base 23 includes a surface 235 facing the light-converting surface 226, and a light-absorbing element 225 is disposed between the surface 235 and the light-converting surface 226.

In this way, the light absorbing element 225 can absorb the light reaching the outside of the light conversion surface 226 of the prism 22 (the mounting base 23), so that the light conversion device 10 can be prevented from forming foreign matters and the like due to the light being refracted by the light conversion surface 226 of the prism 22 to the outside of the light conversion device 10, and the appearance expression and the user experience of the light conversion device 10 can be improved.

The light absorbing element 225 is a black material. For example, the light absorbing element 225 includes at least one of paint and foam. The black material has a good light absorption effect, and the light absorption element 225 made of the black material can simply and conveniently realize the light absorption effect.

In one example, the light absorbing element 225 is a paint, and during the manufacturing process, a black paint may be applied to the back surface 224 of the prism 22, and after the paint is dried, the prism 22 is mounted on the mount 2323. Further, a less fluid paint may be selected to avoid paint flowing to other areas of other prisms 22 that could affect the prisms 22 in turning the light.

In another example, the light absorbing element 225 is foam, and during the manufacturing process, black foam is selected and attached to the backlight surface 224 of the prism 22, and then the prism 22 is mounted on the mount 2323.

In yet another example, the light absorbing elements 225 are paint and foam, and during manufacture, foam may be applied to a portion of the prism 22 between the light-turning surface 226 and the surface 235 of the mount 23 and paint may be applied to another portion.

In this embodiment, the light absorbing element is fixedly disposed on surface 235. Of course, in other embodiments, the light absorbing element is fixedly disposed on the light-turning surface.

It is noted that a gap is formed between the light-turning surface 226 and the surface 235 of the mount 23. Alternatively, the light diverting surface 226 is not in contact with the surface 235 of the mounting base 23. The surface 235 of the mounting seat 23 may be a plane, and may also be a curved surface or a turning surface, and the specific shape of the surface 235 of the mounting seat 23 is not limited herein.

In this embodiment, the surface 235 of the mounting seat 23 is the bottom surface of the accommodating groove. It should be noted that the light absorbing element 225 can be a unitary structure with the mount. For example, the mount 23 is made of black material, so that the surface 235 of the mount 23 has light absorption capability.

Referring to fig. 5-7, in the present embodiment, the two-axis hinge 13 includes a connecting member 14, a limiting structure 15, a first rotating member 16 and a second rotating member 17. The restriction structure 15 serves to restrict the degree of freedom of the mount 23 and the attachment 14 in the direction of the imaging optical axis 102. The first rotating member 16 rotatably connects the lens barrel 11 and the connecting member 14. The first rotating member 16 forms a first rotating shaft 103. The second rotating member 17 rotatably connects the mount 23 and the connecting member 14. The second rotating member 17 forms a second rotating shaft 104.

In this way, the first rotating member 16 and the second rotating member 17 can realize the rotation of the light conversion element 12 in two directions. Specifically, the first rotating member 16 is formed with a first rotating shaft 103 so that the light conversion member 12 can rotate around the first rotating shaft 103 through the connecting member 14. The second rotating member 17 is formed with a second rotating shaft 104 so that the light conversion element 12 can rotate about the second rotating shaft 104.

Referring to fig. 4-6, for convenience of description, the width direction, the height direction and the length direction of the first imaging module 20 are defined as X direction, Y direction and Z direction, respectively. Accordingly, the light entrance axis 101 extends in the Y direction, the imaging optical axis 102 extends in the Z direction, the first rotation axis 103 extends in the X direction, and the second rotation axis 104 extends in the Y direction.

That is, the light conversion element 12 can rotate around the X direction by the first rotation member 16, so that the first imaging module 20 realizes optical anti-shake in the Y direction. In addition, the light conversion element 12 can rotate around the Y direction through the second rotation member 17, so that the first imaging module 20 can realize optical anti-shake in the X direction.

Of course, in other embodiments, the first rotating member 16 may form the second rotating shaft 104, and the second rotating member 17 may form the first rotating shaft 103. That is, the first imaging module 20 can be caused to perform optical anti-shake in the X direction by the first rotating member 16, and the first imaging module 20 can be caused to perform optical anti-shake in the Y direction by the second rotating member 17.

In the present embodiment, the connecting member 14 may have a square shape, an irregular shape, or the like. In addition, the connecting member 14 may be made of plastic, metal, or the like. In order to reduce the weight of the light conversion device 10, the connecting member 14 may be made of a material having a relatively low density. Therefore, in the embodiment of the present application, the shape and material of the connecting member 14 are not limited.

The limiting structure 15 can limit the degree of freedom of the connecting member 14 and the light conversion member 12 in the Z direction, so that the connecting member 14 and the light conversion member 12 can be prevented from falling apart.

Referring to fig. 6, in an example, the limiting structure 15 includes a first magnetic element 151 and a second magnetic element 152, the first magnetic element 151 is disposed on the lens barrel 11, the second magnetic element 152 is disposed on the light conversion element 12, and the first magnetic element 151 and the second magnetic element 152 are attracted to each other.

In this way, the magnetic elements attract each other, so that the degree of freedom of the coupling member 14 and the light conversion element 12 in the Z direction can be restricted. Specifically, the lens barrel 11 is formed with a first mounting groove 112. The first magnetic member 151 is disposed in the first mounting groove 112. The light conversion member 12 is formed with a second mounting groove 122, and a second magnetic member 152 is disposed in the second mounting groove 122. This makes the structure among the limiting structure 15, the lens barrel 11 and the light conversion element 12 more compact, so that the volume of the light conversion device can be reduced.

In the present embodiment, the first mounting groove 112 is formed in the side wall 214 of the lens barrel 11. The second mounting groove 122 is formed at the mounting seat 23.

Referring to fig. 7, in another example, the limiting structure 15 includes a first flexible element 153 and a second flexible element 154, the first flexible element 153 connects the lens barrel 11 and the connecting member 14, and the second flexible element 154 connects the connecting member 14 and the light converting element 12. The first flexible element 153 and the second flexible element 154 are elastic elements such as metal wires and plastic parts.

As shown in fig. 6 and 7, in the present embodiment, the connecting member 14 and the lens barrel 11 together define a first accommodating space 141, and the first rotating member 16 is disposed in the first accommodating space 141. In addition, the light conversion element 12 and the connecting member 14 together define a second receiving space 142, and the second rotation member 17 is disposed in the second receiving space 142. The first and second receiving spaces 141 and 142 may make the structure of the biaxial hinge 13 more compact, thereby reducing the volume of the light conversion device 10.

Specifically, the connecting member 14 and the side wall 214 together define the first receiving space 141. The connecting member 14 and the mounting seat 23 together define a second receiving space 142. The first and second receiving spaces 141 and 142 may have a cylindrical shape or a spherical shape.

The first rotating member 16 rotatably connects the side wall 214 and the connecting member 14. The first rotating member 16 includes rollers and/or balls. That is, the first rotating member 16 may be a roller or a ball, or the first rotating member 16 includes a roller and a ball. It will be appreciated that the rollers are elongate. The ball is spherical. The first rotating member 16 may be made of metal or plastic. In order to reduce the friction of the first rotating member 16, the surface of the first rotating member 16 may be provided with a film made of teflon or the like having a low friction coefficient.

The number of the first rotating members 16 is plural, and the plural first rotating members 16 are arranged at intervals along the first rotating shaft 103. For example, the number of the first rotating members 16 is 2, 3, or 4, etc. As mentioned above, it is understood that some of the first rotating members 16 may be rollers, and other some of the first rotating members 16 may be balls.

The second rotating member 17 rotatably connects the mount 23 and the connecting member 14. The second rotation member 17 comprises rollers and/or balls. That is, the second rotating member 17 may be a roller or a ball, or the second rotating member 17 includes a roller and a ball. It will be appreciated that the rollers are elongate. The ball is spherical. The second rotating member 17 may be made of metal or plastic. In order to reduce the friction of the second rotation member 17, the surface of the second rotation member 17 may be provided with a film made of teflon or the like having a low friction coefficient.

The number of the second rotating members 17 is plural, and the plural second rotating members 17 are arranged at intervals along the second rotating shaft 104. For example, the number of the second rotating members 17 is 2, 3, or 4, etc. As mentioned above, it is understood that some of the second rotating members 17 may be rollers, and another portion of the second rotating members 17 may be balls.

Referring to fig. 6 and fig. 7 again, the light conversion device 10 further includes a driving device 28, and the driving device 28 is used for driving the mounting base 23 with the prism 22 to rotate around the first rotating shaft 103 and the second rotating shaft 104.

In this way, the driving device 28 drives the mounting base 23 to move in two directions, which not only can achieve the optical anti-shake effect of the first imaging module 20 in two directions, but also can make the first imaging module 20 smaller in size.

The driving device 28 drives the mounting base 23 to rotate, so that the prism 22 rotates around the X direction, and the first imaging module 20 achieves the Y-direction optical anti-shake effect. In addition, the driving device 28 drives the mounting seat 23 to move along the axial direction of the rotation axis 29, so that the first imaging 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 prism 22 rotates in the X direction, the light turned by the prism 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 prism 22 moves along the X direction, the light turned by the prism 22 moves in the X direction, so that the first image sensor 26 forms different images in the X direction to achieve the anti-shake effect in the X direction.

Referring to fig. 6-7 and 12 again, the driving device 28 includes an inductive element 281, a first electromagnetic element 282, a third magnetic element 283, a driving circuit board 285, a second electromagnetic element 286, and a fourth magnetic element 287.

The inductive element 281 is disposed outside the first electromagnetic element 282. The sensing element 281 is used to detect the rotation angle of the prism 22. The first electromagnetic element 282 is disposed on the prism 22 side. The first electromagnetic element 282 is used for driving the prism 22 to rotate according to the data detected by the sensing element 281 so as to enable the first imaging module 20 to realize optical anti-shake.

Further, the first electromagnetic element 282 is used for driving the mounting base 23 to rotate according to the data detected by the sensing element 281 to drive the prism 22 to rotate.

Alternatively, the inductive element 281 is a hall sensor, the first electromagnetic element 282 is a coil, and the third magnetic element 283 is a permanent magnet.

So, inductive element 281 sets up in the first electromagnetic element 282 outside, and when the offset of inductive element 281 was gone into in the assembling process, the inductive data deviation that can avoid detecting was great, when guaranteeing that inductive element 281 normally participates in optics anti-shake, can improve the precision of the data that inductive element 281 gathered, is favorable to improving optics anti-shake's accuracy.

The related art generally arranges the hall sensor at the center of the coil so that the initial value of the hall sensor is 0, thereby maximizing the span of the hall sensor. However, during the assembly of the components, the positions of the components may shift, resulting in errors in the data measured by the hall sensor. For example, a hall sensor is placed in the center of a coil, the hall sensor is initially 0mv, and after assembly, the offset in position causes the hall sensor to actually deviate by 10mv, where the effect of the deviation is 100%.

If the hall sensor is arranged outside the coil, the hall sensor forms a non-zero initial value, which reduces the influence of the offset. For example, when the hall sensor is disposed outside the coil, the initial value of the hall sensor is 140mv, and when the hall sensor is assembled, the positional deviation causes a deviation of 10mv in practice, and the effect of the deviation is 7%.

The definition U direction is a direction in which the prism 22 moves in the X direction, and the definition V direction is a direction in which the prism 22 rotates around the X direction.

Referring to fig. 13 and 14, the U direction is defined as a direction in which the prism 22 moves in the X direction, and the V direction is defined as a direction in which the prism 22 rotates around the X direction.

Fig. 13 is a simulation result of deviation ratios of U-direction and V-direction hall sensors in the related art. Fig. 14 is a simulation result of the deviation ratios of the hall sensors in the U direction and the V direction in the present application. Where the horizontal axis is the deviation ratio and the vertical axis is the number of samples that fall within the corresponding deviation ratio. The deviation ratio (%) - ((actual value-center value)/range of the hall sensor) × 100%. The range of the Hall sensor is in the range of +/-1.5 degrees.

As can be seen from fig. 13 and 14, compared to the prior art, the present application has more concentrated data in the V direction, i.e., the deviation ratio is smaller. Further, the deviation ratio of the Hall sensor in the V direction can be reduced to one thousandth of the deviation ratio of the prior art.

Referring to fig. 12, the first electromagnetic element 282 is disposed on the bottom wall 216. The first electromagnetic element 282 is annular, the first electromagnetic element 282 has a first centerline 2821, and the inductive element 281 is disposed offset from the first centerline 2821. The distance A between the center of inductive element 281 and the first centerline 2821 of first electromagnetic element 282 is in the range of 0.5mm-1.0 mm.

When the distance a between the center of the inductive element 281 and the first center line 2821 of the first electromagnetic element 282 is in the range of 0.5mm to 1.0mm, the initial value after the offset is suitable. It can be understood that the initial value after the deviation cannot be too small, so that the deviation rate cannot be reduced more; the initial value after the offset also cannot be too large, which can result in insufficient measurement range of the hall sensor.

Preferably, the center of inductive element 281 is 0.75mm from first centerline 2821 of first electromagnetic element 282.

In another example, the center of inductive element 281 is at a distance A of 0.5mm from first centerline 2821 of first electromagnetic element 282; in yet another example, the center of inductive element 281 is at a distance A of 0.8mm from first centerline 2821 of first electromagnetic element 282; in yet another example, the center of inductive element 281 is 1mm from first centerline 2821 of first electromagnetic element 282. The specific value of the distance a between the center of inductive element 281 and the first centerline 2821 of first electromagnetic element 282 is not limited herein.

It is understood that the first electromagnetic element 282 may be circular, square, or any other shape, and the specific shape of the first electromagnetic element 282 is not limited herein.

Additionally, while in the example of FIG. 12 inductive element 281 is located on one side of first electromagnetic element 282, it is to be understood that in other examples inductive element 281 may be located on the other side of first electromagnetic element 282. The specific location of the sensing element 281 is not limited herein as long as the sensing element 281 does not interfere with the existing structure of the first imaging module 20.

The first electromagnetic element 282 has a second center line 2822, the second center line 2822 is perpendicular to the first center line 2821, the second center line 2822 intersects the first center line 2821 at the center of the first electromagnetic element 282, the number of the inductive elements 281 is two, and the two inductive elements 281 are symmetrically disposed about the second center line 2822 of the first electromagnetic element 282.

In this way, the data measured by the first electromagnetic element 282 can be made more accurate. Specifically, the data output by the two first electromagnetic elements 282 may be calculated, such as averaged, to obtain more accurate data. In addition, when one of the first electromagnetic elements 282 is abnormal, the other first electromagnetic element 282 may ensure normal optical anti-shake operation, which is beneficial to improving the reliability of the driving device 28.

Of course, in other examples, the number of the sensing elements 281 may also be 3, 4 or any other number, and the specific number of the sensing elements 281 is not limited herein.

The third magnetic element 283 is disposed on the light conversion element 12. Specifically, the third magnetic element 283 is disposed on the mounting seat 23, and the first electromagnetic element 282 and the third magnetic element 283 cooperate to drive the light conversion element 12 to rotate around the first rotation axis 103.

In this way, the prism 22 can be rotated by driving the mount 23 to rotate, thereby achieving optical anti-shake. Specifically, after the sensing element 281 detects the rotation angle, the processor may determine, according to the data, a voltage that should be applied to the first electromagnetic element 282, the first electromagnetic element 282 generates a magnetic field after the voltage is applied, and the third magnetic element 283 is affected by the magnetic field, so as to drive the mounting base 23 to rotate to compensate for the shake of the first imaging module 10. This achieves optical anti-shake.

A gap 284 is formed between the inductive element 281 and the third magnetic element 283. Dimension B of gap 284 ranges from 0.20mm to 0.25mm as shown in fig. 5.

Thus, a space for the rotation of the third magnetic element 283 and the mounting seat 23 can be avoided, and it is ensured that the third magnetic element 283 and the mounting seat 23 do not interfere with the sensing element 281 during the rotation process. Specifically, gap 284 is an air gap.

Preferably, the dimension B of the gap 284 is 0.22 mm. In another example, the size of gap 284 is 0.20 mm; in yet another example, dimension B of gap 284 is 0.21 mm; in yet another example, the dimension B of the gap 284 is 0.25 mm. The specific value of dimension B of gap 284 is not limited herein.

The driving circuit board 285 is disposed inside the lens barrel. Further, the drive circuit board 285 is provided at the bottom wall 216. First electromagnetic element 282 and inductive element 281 are both disposed on drive circuit board 285. That is, the first electromagnetic element 282 and the induction element 281 are provided at the bottom wall 216 through the driving circuit board 285.

Thus, while the driving circuit board 285 supplies power to the first electromagnetic element 282, the structure of the first imaging module 20 can be made more compact, which is beneficial to miniaturization of the first imaging module 20. Specifically, the driver circuit board 285 may be a flexible circuit board, a printed circuit board, or other type of circuit board.

The driver circuit board 285 may be soldered, bonded, etc. to the bottom wall 216. In one example, the driving circuit board 285 may be attached to the bottom wall 216 by an adhesive tape.

In the assembling process, the first electromagnetic element 282 and the inductive element 281 may be fixed on the driving circuit board 285, the driving circuit board 285 is attached to the bottom wall 216, and finally the bottom wall 216 is assembled to the housing 21. So, simple and convenient can improve the efficiency of equipment.

Note that the drive circuit board 285 is provided at the bottom wall 216 of the lens barrel. It may be referred that the driving circuit board 285 is fixed in contact with the bottom wall 216 of the housing 21, or that the driving circuit board 285 is fixedly connected to the bottom wall 216 of the housing 21 through other components.

The second electromagnetic element 286 is disposed at the sidewall 214. As shown in the orientation in fig. 7, the second electromagnetic element 286 is provided on the side wall 214 in the X direction of the lens barrel 11. The fourth magnetic element 287 is arranged at the mounting 23. As shown in the orientation in fig. 7, the second electromagnetic element 286 is provided at a position of the mount 23 in the X direction. The fourth magnetic element 287 and the second electromagnetic element 286 cooperate to drive the light conversion element 12 to rotate around the second rotation axis 104.

As such, the fourth magnetic element 287 cooperates with the second electromagnetic element 286 to enable the first imaging module to achieve an optical anti-shake effect in the X direction. The second electromagnetic element 286 is, for example, a coil. The fourth magnetic element 287 is, for example, a permanent magnet.

In the present embodiment, the number of the second electromagnetic elements 286 is two, and the second electromagnetic elements are provided on the two side walls 214 of the lens barrel 11 in the X direction. Accordingly, the number of the fourth magnetic elements 287 is two, and the fourth magnetic elements are respectively disposed on both sides of the mount 23 in the X direction. The two second electromagnetic elements 286 cooperate to drive the prism 22 to rotate around the second rotation axis 104. The amount of electromagnetism formed by the two second electromagnetic elements 286 can be calculated by difference, thereby accurately controlling the angle of rotation of the prism 22.

In this embodiment, the housing 21 is a protection element of the first imaging module 20, which can reduce the impact on the first lens assembly 24. In the present embodiment, the housing 21 has a substantially rectangular parallelepiped shape. The housing 21 is connected to the lens barrel 11. Further, the housing 21 and the lens barrel 11 are of an integral structure. Alternatively, the light conversion device 10 is integrated into the first imaging module 20. Of course, in other embodiments, the housing 21 and the lens barrel 11 are separate structures.

Referring to fig. 5, the first lens element 24 is accommodated in the loading element 25, and further, the first lens element 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 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, thereby realizing the focusing of the first imaging 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 the first imaging module 20, and further, the loading element 25 is driven by the driving mechanism 27 to move in the housing 21 for zooming.

In the example of fig. 5, the mounting element 25 is cylindrical, and the plurality of lenses 241 of the first lens assembly 24 are fixed in the mounting element 25 at intervals along the axial direction of the mounting element 25. As in the example of fig. 15, the loading element 25 includes two clips 252, the two clips 252 sandwiching the lens 241 between the two clips 252.

It can be understood that, since the loading element 25 is used for fixing and arranging the plurality of lenses 241, the length of the loading element 25 is required to be large, and the loading element 25 may be a cylindrical structure, a square cylindrical structure, or the like with a cavity. Thus, the loading element 25 is cylindrical, and the loading element 25 can better set a plurality of lenses 241 and better protect the lenses 241 in the cavity, so that the lenses 241 are not easy to shake.

In the example of fig. 15, the loading element 25 has a certain stability by clamping the plurality of lenses 241 between the two clamping pieces 252, and the weight of the loading element 25 can be reduced, so that the power required by the driving mechanism 27 to drive the loading element 25 can be reduced, the design difficulty of the loading element 25 is low, and the lenses 241 can be easily installed on the loading element 25.

Of course, the loading element 25 is not limited to the above-mentioned cylindrical shape and two clips 252, and in other embodiments, the loading 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 first image sensor 26 may employ a Complementary Metal Oxide Semiconductor (CMOS) photosensitive element or a Charge-coupled Device (CCD) photosensitive element.

The driving mechanism 27 is an electromagnetic driving mechanism, a piezoelectric driving mechanism, or a memory alloy driving mechanism.

Specifically, in the case where the driving mechanism 27 is an electromagnetic driving mechanism, the driving mechanism 27 includes a magnet for generating a magnetic field and a conductor for moving the loading element 25. When the magnetic field moves relative to the conductor, an induced current is generated in the conductor, causing the conductor to be subjected to an ampere force which drives the loading element 25 in motion.

In the case where the driving mechanism 27 is a piezoelectric driving mechanism, a voltage may be applied to the driving mechanism 27 based on the inverse piezoelectric effect of the piezoelectric ceramic material so that the driving mechanism 27 generates a mechanical stress. That is, the driving mechanism 27 is controlled to be mechanically deformed by the conversion between the electric energy and the mechanical energy, thereby driving the loading element 25 to move.

In the case where the drive mechanism 27 is a memory alloy drive mechanism, the drive mechanism 27 may be made to memorize a preset shape in advance. When it is desired to drive the movement of the loading element 25, the driving mechanism 27 may be heated to a temperature corresponding to the preset shape to restore the driving mechanism 27 to the preset shape, thereby driving the movement of the loading element 25.

Referring to fig. 16, in the present embodiment, the second imaging module 30 is an upright lens module, but in other embodiments, the second imaging module 30 may also be a periscopic camera module.

The second imaging module 30 includes a second lens assembly 31 and a second image sensor 32, the second lens assembly 31 is configured to image light onto the second image sensor 32, and an incident optical axis of the second imaging module 30 coincides with an optical axis of the second lens assembly 31.

In this embodiment, the second imaging module 30 can be 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 imaging 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 herein.

The third imaging module 40 has a structure similar to that of the second imaging module 30, for example, the third imaging module 40 is also an upright lens module. Therefore, the features of the third imaging module 40 refer to the features of the second imaging module 40, which are not described herein.

Referring to fig. 17, fig. 17 shows a schematic structural diagram of an electronic device 1000 according to another embodiment of the present application, and as shown in the example of fig. 17, unlike the example of fig. 1, in the example of fig. 17, the electronic device 1000 includes an extending module 130, the extending module 130 is configured to move between a first position housed in the housing 110 and a second position extending out of the housing 110, the extending module 130 is provided with a flashlight 60, and when the extending module 130 is located at the second position, the flashlight 60 is located outside the housing 110.

That is, the flash 60 is provided separately from the camera assembly 100. The extension module 130 may slide out of the housing 110 or rotate out of the housing 110. In this application, the extension module 130 rotates the extension housing 110. The extension module 130 may also be provided with a front camera. When the extension module 130 extends out of the housing 110, the electronic device 1000 may perform front shooting.
