[0027] The following is combined Figures 1-7 This invention describes a camera module and an electronic device according to embodiments of the present invention.

[0028] like Figure 1 As shown, a camera module according to some embodiments of the present invention includes: a housing 1 and a carrier 2, a rotating member 3, a first image stabilization component 4, and a second image stabilization component 5 disposed within the housing 1, wherein the carrier 2 is sleeved on the rotating member 3, and the rotating member 3 is used to mount the camera; the first image stabilization component 4 is connected to the carrier 2 and the housing 1 respectively, and is used to drive the carrier 2 to move along a first direction and / or a second direction, the plane containing the first direction and the second direction being a target plane; the second image stabilization component 5 is connected to the carrier 2 and the rotating member 3 respectively, and is used to drive the rotating member 3 to rotate around a target straight line, the target straight line being parallel to the target plane.

[0029] In the embodiments of this application, the first image stabilization component 4 drives the carrier 2 to move along a first direction and / or a second direction. The carrier 2 can drive the rotating component 3 to move along the first direction and / or the second direction. The rotating component 3 can drive the camera to move along the first direction and / or the second direction, thereby achieving the image stabilization function of the camera. The second image stabilization component 5 drives the rotating component 3 to rotate linearly around the target. The rotating component 3 can drive the camera to rotate linearly around the target, thereby achieving the image stabilization function of the camera. Thus, when one of the first image stabilization component 4 and the second image stabilization component 5 is controlled, the camera can achieve small-angle image stabilization; when the first image stabilization component 4 and the second image stabilization component 5 are controlled to work together, the camera can achieve large-angle image stabilization.

[0030] In this embodiment, the housing 1 is the main structure of the camera module, used to install and protect the carrier 2, rotating component 3, first image stabilization component 4, second image stabilization component 5, camera, etc. The rotating component 3 can be used to mount the camera, and the rotating component 3 can be rigidly connected to the camera so that the rotating component 3 can drive the camera to rotate, thereby achieving the image stabilization function.

[0031] Specifically, the housing 1 can be the stator structure of the camera module, and the carrier 2 and the rotating component 3 can be the moving component structure of the camera module.

[0032] Specifically, the carrier 2 is sleeved outside the rotating part 3, and the rotating part 3 and the carrier 2 can be movably connected. The rotating part 3 can move relative to the carrier 2, and the carrier 2 can also drive the rotating part 3 to move synchronously.

[0033] Specifically, the first image stabilization component 4 is connected to both the carrier 2 and the housing 1, and can drive the carrier 2 to move along a first direction and / or a second direction; the second image stabilization component 5 is connected to both the carrier 2 and the rotating component 3, and is used to drive the rotating component 3 to move linearly around the target. In this embodiment, under the action of the first image stabilization component 4, the rotating component 3 and the carrier 2 move synchronously, and the carrier 2 can drive the camera to move along the first direction and / or the second direction, providing a certain value of image stabilization angle through translation; under the action of the second image stabilization component 5, the rotating component 3 can drive the camera to rotate linearly around the target, providing a certain value of image stabilization angle through rotation, enabling the camera to move in multiple directions, facilitating large-angle image stabilization.

[0034] For example, the target line can be as follows: Figure 7 The S-shaped line shown.

[0035] Furthermore, when at least one of the first image stabilization component 4 and the second image stabilization component 5 is in operation, the carrier 2 can drive the camera to achieve small-angle image stabilization; when the first image stabilization component 4 and the second image stabilization component 5 are in operation simultaneously, the carrier 2 can drive the camera to achieve large-angle image stabilization. In this embodiment, the camera module can achieve large-angle image stabilization with minimal change in size.

[0036] Specifically, the first image stabilization component 4 and the second image stabilization component 5 are set independently, which can realize independent control of the camera's rotation and translation, and can also achieve a high response speed.

[0037] Optionally, the rotating component 3 is provided with a mounting hole 31 for mounting a camera to improve the reliability of assembling the rotating component 3 and the camera.

[0038] Specifically, the mounting hole 31 can be adapted to a camera, and its specific shape and size can be set with reference to the camera. This application embodiment does not specifically limit this.

[0039] Optionally, the housing 1 includes a top plate and a base 12 disposed opposite to each other along a third direction, and the top plate is provided with a clearance hole; the mounting hole 31 and the clearance hole are opposite to each other along a third direction, and both the mounting hole 31 and the clearance hole are through along a third direction, and the third direction intersects with the target plane.

[0040] In this embodiment, the mounting hole 31 and the clearance hole are opposite each other along a third direction, and both the mounting hole 31 and the clearance hole are through each other along a third direction, so that the camera can collect light through the clearance hole on the top plate, thereby ensuring the camera module's ability to take pictures.

[0041] Optionally, the camera module may further include a driving component, which is connected to the carrier 2. The driving component can drive the carrier 2 to move in a third direction. The carrier 2 can drive the camera to move in the third direction through the rotating component 3, so as to realize the focusing function of the camera module.

[0042] Optionally, the first anti-shake component 4 includes a sliding shaft 41 extending along a third direction. The sliding shaft 41 includes a first end and a second end along the third direction. The housing 1 includes a top plate and a base 12 opposite each other along the third direction. The third direction intersects with the target plane. The sliding shaft 41 passes through the carrier 2. The first end is movably connected to the top plate along the first direction and / or the second direction. The second end is movably connected to the base 12 along the first direction and / or the second direction.

[0043] In this embodiment of the application, when the carrier 2 moves along the first direction and / or the second direction, the first end of the sliding shaft 41 can move relative to the top plate along the first direction and / or the second direction, and the second end of the sliding shaft 41 can move relative to the base 12 along the first direction and / or the second direction, which can improve the reliability and stability of the first anti-shake component 4 driving the carrier 2 to move along the first direction and / or the second direction.

[0044] Specifically, the carrier 2 may be provided with a through hole 21; the sliding shaft 41 may be passed through the through hole 21 to improve the reliability of the sliding fit between the carrier 2 and the sliding shaft 41.

[0045] Specifically, the camera module also includes a bushing 47, which can be embedded in the through hole 21; the sliding shaft 41 can be inserted through the bushing 47 to reduce the friction between the sliding shaft 41 and the carrier 2.

[0046] Optionally, the first anti-shake component 4 includes two first balls 42; both the first and second ends are provided with first limiting grooves, and the top plate and the base 12 are provided with rolling grooves, the rolling grooves being opposite to the first limiting grooves, and the rolling grooves, the first limiting grooves, and the first balls 42 being correspondingly arranged; part of the first ball 42 is embedded in the corresponding first limiting groove, and the other part is embedded in the corresponding rolling groove and movably connected to the corresponding rolling groove; the orthographic projection of the rolling groove in the target plane is greater than the orthographic projection of the corresponding first ball 42 in the target plane.

[0047] In this embodiment, the rolling groove, the first limiting groove, and the first ball 42 are correspondingly arranged. Part of the first ball 42 is embedded in the corresponding first limiting groove, and the other part is embedded in the corresponding rolling groove and movably connected to the corresponding rolling groove. The orthographic projection of the rolling groove in the target plane is greater than the orthographic projection of the corresponding first ball 42 in the target plane, so that the first limiting groove can limit the movement range of the first ball 42, thereby limiting the movement range of the carrier 2, and finally limiting the movement range of the camera to ensure the image stabilization capability of the camera module.

[0048] Specifically, rolling grooves are provided on the base 12 and the top plate, and the first ball 42 rolls within the rolling grooves, which can also meet the requirements for greater load-bearing capacity. The rolling grooves can also be used to limit the range of motion of the first ball 42.

[0049] Specifically, a protrusion 122 may be provided on the side of the base 12 facing the top plate. The protrusion 122 may have the aforementioned rolling groove, or the protrusion 122 may be formed by enclosing the base 12 to form a rolling groove with its opening facing the top plate. Similarly, the arrangement of the rolling groove on the top plate can refer to the arrangement of the rolling groove on the base 12, and will not be described again in this embodiment.

[0050] Specifically, the first ball 42 can be fixedly connected in the first limiting groove so that the first ball 42 can slide in the rolling groove; or, the first ball 42 can also be tactilely connected to the first limiting groove so that the first ball 42 can roll along the rolling groove.

[0051] Specifically, when the carrier 2 moves along the first direction and / or the second direction, it can drive the sliding shaft 41 to move along the first direction and / or the second direction. The sliding shaft 41 can drive the first ball 42 to move along the first direction and / or the second direction. The first ball 42 can only move within the rolling groove, thereby ensuring the reliability of the carrier 2 moving along the first direction and / or the second direction.

[0052] Specifically, the target plane can be parallel to the top plate and the base 12 respectively, and the bottom of the first rolling groove can also be parallel to the target plane to ensure the reliability of the carrier 2 moving along the first direction and / or the second direction.

[0053] Specifically, the corresponding rolling groove, first limiting groove, and first ball 42 can be combined to form a first limiting component, and a set of first limiting components can be set at each end of the sliding shaft 41.

[0054] Optionally, the first anti-shake component 4 further includes two first elastic elements 43 and two elastic elements 44; the first elastic element 43 is disposed between the carrier 2 and the top plate, and the first elastic element 43 is connected to one end of the carrier 2 and the top plate respectively; the second elastic element 44 is disposed between the carrier 2 and the base 12, and the second elastic element 44 is connected to the other end of the carrier 2 and the base 12 respectively.

[0055] In this embodiment, the first elastic member 43 is disposed between the carrier 2 and the top plate, and the second elastic member 44 is disposed between the carrier 2 and the base 12. In this way, under the elastic action of the first elastic member 43 and the second elastic member 44, the carrier 2 can be prevented from hitting the top plate or the base 12, thus avoiding noise.

[0056] Specifically, under the rebound action of the first elastic element 43 and the second elastic element 44, after the driving force of the carrier 2 disappears, the first elastic element 43 and the second elastic element 44 can drive the carrier 2 back to its original position and ensure that the carrier 2 remains in its original position.

[0057] Specifically, when the carrier 2 is subjected to a driving force, the first elastic element 43 and the second elastic element 44 can accumulate elastic potential energy; after the driving force on the carrier 2 disappears, the first elastic element 43 and the second elastic element 44 release the elastic potential energy and drive the carrier 2 to reset. When the carrier 2 is subjected to a driving force, it is also subjected to the elastic force of the first elastic element 43 and the second elastic element 44. When the driving force and the elastic force on the carrier 2 are balanced, the position of the carrier 2 is stable, which is beneficial to achieving anti-shake.

[0058] Specifically, the first elastic element 43 can be a spring or a sheet, and it can be a ring-shaped element to ensure the uniformity of force on the carrier 2. The second elastic element 44 can be configured with reference to the first elastic element 43, which will not be described in detail in this embodiment.

[0059] Optionally, such as Figure 2 As shown, the first anti-shake component 4 also includes a magnetic component 45 and an electromagnetic component 46. The housing 1 also includes a circumferential side plate 13. One end of the circumferential side plate 13 along a third direction is connected to the top plate, and the other end of the circumferential side plate 13 along a third direction is connected to the base 12. The magnetic component 45 is disposed on the side of the carrier 2 facing the circumferential side plate 13, and the electromagnetic component 46 is disposed on the side of the circumferential side plate 13 facing the carrier 2. The electromagnetic component 46 is disposed opposite to the magnetic component 45, and the electromagnetic component 46 is connected to the power supply.

[0060] In this embodiment, energizing the electromagnetic component 46 can drive the magnetic component 45 to move, and the magnetic component 45 can drive the carrier 2 to move. This application drives the carrier 2 to move through electromagnetic drive, which is simple and convenient.

[0061] Specifically, electromagnetic components 46 and magnetic components 45 can be arranged in a one-to-one correspondence. The number of magnetic components 45 can be one, two, or more, etc., and at least two magnetic components 45 can be evenly spaced along the circumferential side plate 13. For example... Figure 2 The illustration only shows one case where four magnetic elements 45 are arranged around the perimeter of the circumferential side plate 13. Other cases can be set with reference to this, and this application embodiment does not make specific limitations on this.

[0062] Specifically, the electromagnetic component 46 can be a coil that generates a magnetic field when energized. The magnetic component 45 can be a magnet or lodestone, etc.

[0063] Specifically, a receiving groove 25 may be provided on the side of the carrier 2 facing the circumferential side plate 13, and at least a portion of the magnetic component 45 may be embedded in the receiving groove 25.

[0064] Specifically, the circumferential side plate 13 and the top plate can be integrally formed or welded together, and the circumferential side plate 13 and the base 12 can be welded together or bonded together.

[0065] Optionally, combined Figures 3-7 As shown, the carrier 2 is provided with a through hole 22 extending along a third direction, which intersects with the target plane. The hole wall of the through hole 22 forms a first spherical arc surface 23, and the outer peripheral surface of the rotating part 3 is a second spherical arc surface 33. The rotating part 3 is embedded in the through hole 22, and the second spherical arc surface 33 slides with the first spherical arc surface 23.

[0066] In this embodiment, the second spherical arc surface 33 and the first spherical arc surface 23 are slidably engaged, which facilitates the shape adaptation of the second spherical arc surface 33 and the first spherical arc surface 23, thereby avoiding jamming during the rotation of the rotating part 3 and ensuring the reliability of the anti-shake mechanism.

[0067] Specifically, the centers of the second spherical arc surface 33 and the first spherical arc surface 23 can be close to or coincide.

[0068] Optionally, the centers of the first spherical arc surface 23 and the second spherical arc surface 33 coincide, and the target straight line passes through the center of the sphere. In this way, the gap between the rotating component 3 and the carrier 2 can remain unchanged during the rotation of the rotating component 3, which can further ensure the reliability of the anti-shake.

[0069] Optionally, the second anti-shake component 5 includes a second ball bearing 51; a second limiting groove 32 is provided on the side of the rotating member 3 facing the carrier 2, and an arc-shaped groove 24 is provided on the side of the carrier 2 facing the rotating member 3, the arc-shaped groove 24 is opposite to the second limiting groove 32, and the arc-shaped groove 24 extends along a third direction; part of the second ball bearing 51 is embedded in the second limiting groove 32, and another part is embedded in the arc-shaped groove 24 and is movably connected to the arc-shaped groove 24.

[0070] In this embodiment, the second ball 51 is movably connected to the arc groove 24, so that the arc groove 24 can restrict the running trajectory of the second ball 51, thereby restricting the rotation path of the rotating member 3 and improving the accuracy of the anti-shake angle control.

[0071] Specifically, the second ball 51 can be fixedly connected to the second limiting groove 32, so that the second ball 51 can slide in the arc groove 24; or, the second ball 51 can also be tumbledly connected to the second limiting groove 32, so that the second ball 51 can roll in the arc groove 24.

[0072] Specifically, the second ball 51, the second limiting groove 32 and the arc groove 24 are set in a one-to-one correspondence. The corresponding second ball 51, the second limiting groove 32 and the arc groove 24 can be combined to form a second limiting component. The number of second limiting components can include two sets, and the two sets of second limiting components can be set symmetrically relative to the target line.

[0073] Specifically, in combination Figure 1 and Figure 5 As shown, in some embodiments, the number of second limiting components is four, and the corresponding target straight line may include two lines.

[0074] Optionally, the second anti-shake component 5 further includes an electrodeformable element 54; the electrodeformable element 54 is disposed between the carrier 2 and the rotating element 3, and is connected to the carrier 2 and the rotating element 3 respectively; the electrodeformable element 54 is connected to a power source, and the electrodeformable element 54 deforms when energized to drive the rotating element 3 to move.

[0075] In this embodiment, the rotating member 3 can be driven to move by the electro-deformable member 54, which is simple and convenient.

[0076] Specifically, the electrodeformable element 54 can deform when energized, so that the deformation force of the electrodeformable element 54 can drive the rotating element 3 to move. The electrodeformable element 54 can be made of an electrodeformable material. When the electrodeformable element 54 is energized, its length can be shortened so that the electrodeformable element 54 applies a tensile force to the rotating element 3, thereby driving the rotating element 3 to rotate; or, when the electrodeformable element 54 is energized, its length can be extended so that the electrodeformable element 54 can compress the rotating element 3, thereby driving the rotating element 3 to rotate.

[0077] Furthermore, the length of the electro-deformable element 54 can be adjusted by the magnitude of the current.

[0078] Specifically, by changing the adjustable length range of the electrodeformation element 54, the second image stabilization component 5 can also drive the camera independently to achieve large-angle image stabilization.

[0079] Optionally, the second anti-shake component 5 further includes a third elastic element 52, which is connected to the carrier 2 and the electrodeformable element 54 respectively; the third elastic element 52 is connected to a power source to connect the electrodeformable element 54 to the power source.

[0080] In this embodiment, the third elastic element 52 is connected to the carrier 2 and the electrodeformable element 54 respectively. In this way, after the electrodeformable element 54 is de-energized, the third elastic element 52 can drive the electrodeformable element 54 to reset, which facilitates the subsequent implementation of the anti-shake function.

[0081] Specifically, the third elastic element 52 can be a spring or a sheet, etc., which can be selected according to actual needs.

[0082] Specifically, this embodiment of the application only uses the electrodeformable element 54 as a suspension wire for illustration. Multiple suspension wires can be arranged at intervals along the circumference of the rotating element 3. The third elastic element 52 can be an annular element, so that the third elastic element 52 is adapted to the rotating element 3, which can improve the reliability and uniformity of the force on the rotating element 3.

[0083] Specifically, the evenly spaced arrangement of multiple suspension wires can further improve the reliability and uniformity of the force applied to the rotating component 3.

[0084] Optionally, the number of electrodeformable elements 54 may include multiple electrodeformable elements 54; multiple electrodeformable elements 54 may be respectively disposed on both sides of the rotating member 3 in a third direction, and / or multiple electrodeformable elements 54 may be respectively disposed on both sides of the rotating member 3 in a fourth direction, the fourth direction being perpendicular to the target line; wherein, the electrodeformable elements 54 on both sides of the rotating member 3 in the third direction are used to apply driving forces in opposite directions to the rotating member 3, and the electrodeformable elements 54 on both sides of the rotating member 3 in the fourth direction are used to apply driving forces in opposite directions to the rotating member 3.

[0085] In this embodiment, the electrodeformable elements 54 on both sides of the rotating member 3 in the third direction apply opposite forces to the rotating member 3, and the electrodeformable elements 54 on both sides of the rotating member 3 in the fourth direction apply opposite forces to the rotating member 3, which facilitates driving the rotating member 3 to rotate around a specific direction, thereby improving the reliability of the anti-shake.

[0086] For example, the rotating member 3 has up-down, front-back, and left-right directions; the multiple electro-deformable members 54 may include a first electro-deformable member, a second electro-deformable member, a third electro-deformable member, and a fourth electro-deformable member; the first and second electro-deformable members may be disposed on the upper side of the rotating member 3, the third and fourth electro-deformable members may be disposed on the lower side of the rotating member 3, the first and third electro-deformable members may be disposed on the left side of the rotating member 3, and the second and fourth electro-deformable members may be disposed on the right side of the rotating member 3.

[0087] Specifically, by having the first electro-deformable element pull upwards to the left side of the rotating element 3, and / or by having the fourth electro-deformable element pull downwards to the right side of the rotating element 3, the rotating element 3 can rotate clockwise around the front-back direction. By having the third electro-deformable element pull downwards to the left side of the rotating element 3, and / or by having the second electro-deformable element pull upwards to the right side of the rotating element 3, the rotating element 3 can rotate counterclockwise around the front-back direction.

[0088] Specifically, referring to the above description, with four electrodeformable elements 54 engaged, the rotating element 3 can rotate clockwise or counterclockwise around the front-back direction, i.e., rotation in two directions. Similarly, with four electrodeformable elements 54 engaged, the rotating element 3 can also rotate clockwise or counterclockwise around the left-right direction, i.e., rotation in two directions. Furthermore, with eight electrodeformable elements 54 engaged, the rotating element 3 can rotate clockwise or counterclockwise around the front-back direction, or the rotating element 3 can rotate clockwise or counterclockwise around the left-right direction, i.e., rotation in four directions.

[0089] Specifically, the exact number of electrodeformable elements 54 can be selected according to actual needs, and this application embodiment does not impose a specific limitation on this.

[0090] Optionally, the camera module may further include a sensor 6 and a control unit. The control unit is connected to the sensor 6 and a power supply, respectively. The control unit can control the power supply to supply power to the electrodeformable element 54 and / or the electromagnetic element 46 according to the detection signal fed back by the sensor 6.

[0091] The camera module described in this application embodiment has at least the following advantages:

[0092] In the embodiments of this application, the first image stabilization component drives the carrier to move along the first direction and / or the second direction. The carrier can drive the rotating component to move along the first direction and / or the second direction, and the rotating component can drive the camera to move along the first direction and / or the second direction, thereby achieving the image stabilization function of the camera. The second image stabilization component drives the rotating component to rotate linearly around the target, and the rotating component can drive the camera to rotate linearly around the target, thereby achieving the image stabilization function of the camera. Thus, when one of the first and second image stabilization components is controlled, the camera can achieve small-angle image stabilization; when both the first and second image stabilization components are controlled to work together, the camera can achieve large-angle image stabilization.
