TECHNICAL FIELD

The present disclosure relates to the technical field of camera devices and, in particular, to a camera device and a portable electronic device.

BACKGROUND

With the rapid development of photographing technology, camera devices including lenses are widely used in various portable electronic devices, such as portable phones, tablet computers, and the like.

In general, a camera device applied to a general portable electronic device includes a drive mechanism for adjusting the focus in an optical axis direction and a camera shake correction mechanism for driving in a plane orthogonal to the optical axis direction.

The driving function is achieved by coils and magnets, and the coils are fixed to an outer periphery of a lens carrier. When a current is applied to the coil, the coil moves the lens carrier along the optical axis direction of the lens under the action of electromagnetic force, thereby enabling focusing.

In addition, when a user takes an image while holding the electronic device by hand, the camera shake can be corrected by driving in a direction perpendicular to the optical axis for compensating shake of the camera device caused by the hand.

However, as a small device mounted on for example a portable electronic device, a camera shake correction mechanism in an optical system such as a medium-telephoto lens with a long total optical length is difficult to achieve in a highly integrated miniaturized mechanism with low height due to the length of the driving extent and the weight of the lens.

Moreover, since the drive mechanism for adjusting the focus which is driven in the optical axis direction and the camera shake correction mechanism which is driven in a plane orthogonal to the optical axis are integrated to each other, a mechanism for suppressing natural vibrations and a mechanism for centering adjustment of the lens and the like are further needed. As a result, time-consuming assembling and difficulty of design tend to increase.

Embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, but not to be construed as limitations to the present disclosure.

As shown fromFIG.1toFIG.11, an embodiment of the present disclosure provides a camera device10, which includes a housing100having an accommodation cavity100a, an optical imaging part placed in the accommodation cavity100a, and an anti-shake mechanism300. The optical imaging part includes a lens200having an optical axis500and a drive mechanism400for driving the lens200. The optical imaging part and the anti-shake mechanism300are arranged successively along a direction of the optical axis500, and the lens200is located on a light-receiving side of the optical axis500.

The housing100includes a top wall101, a bottom wall102and a peripheral wall103. The peripheral wall103is connected to the top wall101and the bottom wall102. The accommodation cavity100ais surrounded by the top wall101, the bottom wall102and the peripheral wall103. A through hole104is provided communicating with the accommodation cavity100afor at least part of the lens200to protrude therefrom.

The anti-shake mechanism300includes a first movable part301, a first fixed part302, a first coil306, a first magnet307, a filter303and a photosensitive sensor304. The first fixed part302is fixed in the accommodation cavity100a, and the first movable part301is movably disposed in the accommodation cavity100a. The first movable part301is supported on the first fixed part302through rolling of a ball314. The first movable part301can move in a plane orthogonal to the direction of the optical axis500. The first magnet307is fixed on the first fixed part302. The first coil306, the filter303and the photosensitive sensor304are all fixed on the first movable part301.

The filter303is closer to the light-receiving side of the optical axis500than the photosensor304. In some embodiments, the filter303is an infrared cut filter303, which generally protects the photosensor304and blocks undesired wavelengths, filtering out undesired light and passing only visible light.

The first coil306, the filter303, signal lines and power lines of the photosensitive sensor304can be disposed outside the anti-shake mechanism300through the first flexible conductive substrate308, so as not to block the operation of the anti-shake mechanism300. Optionally, the accommodation cavity100ais provided with space for free movement, so that at least when the curved surface of the first flexible conductive substrate308moves in the plane, it will not block the movement of the anti-shake mechanism300.

The anti-shake mechanism300uses the first movable part301to move the filter303and the photosensitive sensor304in a plane orthogonal to the optical axis500to perform hand-shake correction. At the same time, the first coil306, the filter303and the photosensitive sensor304are fixedly connected to the first movable part301, thereby realizing the low height and miniaturization of the camera device10, simplifying the structure and reducing the occupied space, and improving the quality of the image. The working principle of the above-mentioned anti-shake mechanism300is as follows: when the first coil306is energized, through the interaction between the magnetic field of the first magnet307and the current flowing in the first coil306, a Lorentz force is generated in the first coil306. The direction of the Lorentz force is a direction orthogonal to the direction of the magnetic field of the first magnet307and the direction of the current flowing in the first coil306. Since the first magnet307is fixed, a reaction force acts on the first coil306. This reaction force becomes the driving force of the first movable part301, and the first movable part301having the first coil306moves in a plane orthogonal to the direction of the optical axis500, thereby performing anti-shake correction.

The driving mechanism400includes a second magnet404for driving the lens200to move.

Further, as shown inFIG.5, the first magnet307, the first coil306and the second magnet404are successively arranged at intervals along the optical axis direction. The first magnet307, the first coil306and the second magnet404are successively arranged along the direction of the optical axis500. The first coil306is simultaneously acted by the first magnet307and the second magnet404to drive the first movable part301to move.

By arranging the first magnet307, the first coil306and the second magnet404at intervals along the optical axis direction, and by arranging the first coil306between the first magnet307and the second magnet404, the first coil306can simultaneously use the magnetic fluxes of both the first magnet307and the second magnet404. As a result, the first movable part301having the first coil307can receive a larger driving force, thereby improving the efficiency of anti-shake correction of the camera.

Further, multiple groups of first magnets307and multiple groups of second magnets404are provided. The multiple groups of first magnets307and the multiple groups of second magnets404are arranged in a one-to-one correspondence around the optical axis500. Each group of first magnets307includes two magnets arranged perpendicular to the optical axis500. The two first magnets307have opposite magnetization directions along the direction of the optical axis500. Each group of second magnets404is magnetized along the direction perpendicular to the optical axis500, and each group of second magnets404and one of the corresponding group of first magnets307that is facing the second magnet404have opposite magnetic pole distribution directions.

In some embodiments, as shown inFIG.10, the first magnet307has two layers in the optical axis direction, the polarities of the two layers of the first magnet307are opposite to each other. The S pole of the layer close to the second magnet404is closer to the lens200than the N pole, and the S pole of the layer away from the second magnet404is further away from the lens200than the N pole.

Further, referring toFIG.11, the first movable part301can translate in the first direction D1and the second direction D2orthogonal to the direction of the optical axis500and can rotate in a plane defined by the first direction D1and the second direction D2. The first direction D1is perpendicular to the second direction D2. The anti-shake mechanism300has a first axis315parallel to the first direction D1and a second axis316parallel to the second direction D2, and the optical axis500passes through the intersection point of the first axis315and the second axis316. Multiple groups of first coils306are provided. The multiple groups of first coils306are arranged around the optical axis and are rotationally symmetrical about the intersection point, and the multiple groups of first coils306are asymmetrically distributed with respect to the first axis315and the second axis316. The first coil306can change the direction of rotation of the first movable part301by changing the direction of the current, so that the first movable part301can perform clockwise rotation and counterclockwise rotation in a plane orthogonal to the optical axis500.

Further, as shown inFIGS.6to8, in some embodiments, the main body of the first movable part301is a plate-like structure, and the main body of the first movable part301is provided with a first protrusion3011on the backlight side in the direction of the optical axis500. The first protrusion3011is optionally located in the middle of the first movable part301. The photosensitive sensor304is fixed on the first protrusion3011and can move synchronously with the movement of the first movable part301. A first groove3012is recessed on the end surface of the protrusion3011away from the first movable part301. The first groove3012is configured to accommodate a partial structure of the photosensitive sensor304, so that one end of the photosensitive sensor304extends into the first groove3012. Therefore, the space occupied by the photosensitive sensor304in the direction of the optical axis500can be further compressed and, at the same time, the photosensitive sensor304can be protected. The shape and size of the first groove3012can be determined according to the shape and size of the photosensitive sensor304, which is not limited herein.

A second groove3021is recessed on the light-receiving side of the first fixed part302in the direction of the optical axis500. The second groove3021corresponds to the first groove3012. The second groove3021is configured to accommodate a partial structure of the photosensitive sensor304, so that one end of the photosensitive sensor304extends into the second groove3021. The space occupied by the photosensitive sensor304in the direction of the optical axis500can be further compressed and, at the same time, the photosensitive sensor304can be protected. The shape and size of the second groove3021can be determined according to the shape and size of the photosensitive sensor304, which is not limited herein. Those skilled in the art can understand that the inner diameter of the second groove3021is larger than the photosensitive sensor304extending therein, so that the lateral movement of the photosensitive sensor304in the second groove3021is not blocked, to prevent the movement of the photosensitive sensor304from being limited by the inner wall of the second groove3021.

By accommodating the photosensitive sensor304in the first groove3012and the second groove3021, the projection of the photosensitive sensor304in the direction of the optical axis500overlaps the first movable part301and the first fixed part302. The thicknesses of the first movable part301, the first fixed part302and the photosensitive sensor304are overlapped, thereby reducing the space occupied by the photosensitive sensor304, which is beneficial to the miniaturization of the camera device10, the reduction of components of the photosensitive sensor304and the improvement of the perpendicularity of the photosensitive sensor304with respect to the optical axis500. Moreover, the undesired inclination of the photosensitive sensor304with respect to the optical axis500, the mounting deviation of the photosensitive sensor304in the plane are also alleviated, and the overall rigidity of the photosensitive sensor304as well as the protection against falling shocks can be improved.

Further, referring toFIGS.6to8, a stepped groove3013is provided penetrating through the light-receiving side of the first movable part301in the direction of the optical axis500, and corresponds to the position of the first protrusion3011. The groove3013corresponds to the first groove3012and penetrates to communicate with the first groove3012. The filter303is fixed in the stepped groove3013. The filter303and the photosensitive sensor304are relatively spaced along the direction of the optical axis500. The filter303is closer to the light-receiving side along the direction of the optical axis500. The projection of the filter303in the direction of the optical axis500overlaps the first movable part301. By overlapping the thicknesses, the space occupied by the filter303is reduced, which is beneficial to the miniaturization of the camera device10, the reduction of components of the filter303and the improvement of the perpendicularity of the filter303with respect to the optical axis500. Moreover, the undesired inclination of the filter303with respect to the optical axis500, the mounting deviation of the filter303in the plane are also alleviated, and the overall rigidity of the filter303as well as the protection against falling shocks can be improved.

Further, as shown inFIG.5, the first movable part301is disposed on the light-receiving side of the first fixed part302in the direction of the optical axis500. The first coil306is fixed on one side of the first movable part301facing the first fixed part302. The first coil306is arranged around the photosensitive sensor304. The first magnet307is fixed on the side of the first fixed part302facing the first movable part301. The first magnet307one-to-one corresponds to the first coil306. In some embodiments, multiple first magnets307and multiple first coils306are provided, and the multiple first magnets307and the multiple first coils306are in one-to-one correspondence. Optionally, four first coils306are arranged at equal intervals by taking the photosensitive sensor304as the center. Those skilled in the art can understand that the number and distribution of the first coils306can be determined according to the actual situation, which is not limited herein.

Further, referring toFIG.5andFIG.7, a third groove3014is recessed on the backlight side of the first movable part301in the direction of the optical axis500, and a yoke305is fixed in the third groove3014. The yoke305one-to-one correspond to the magnet307. The yoke305is disposed in the third groove3014, so that the surface of the yoke305is lower than the surface of the first movable part301, which is also beneficial to the miniaturization of the camera device10.

The yoke305is attached to the first movable part301and has a structure tended to be pulled closer to the center of the first magnet307, so as to achieve the magnetic spring effect of pulling the anti-shake mechanism300closer toward the optical axis500by the yoke305and the first magnet307. The yoke305and the first magnet307interact with each other to effectively eliminate looseness, which can reduce the inclination of the first movable part301relative to the optical axis500, and achieve motion reset as well as compressing the ball314.

Further, referring toFIGS.5to8, a second protrusion3015is protruded from the backlight side of the first movable part301in the direction of the optical axis500, and a fourth groove3016is recessed on the end surface of the second protrusion3015facing away from the first movable part301. A first plate312is disposed in the fourth groove3016, and the first plate312is fixed on the bottom surface of the fourth groove3016.

A fifth groove3022is recessed on the light-receiving side of the first fixed part302in the direction of the optical axis500. The fifth groove3022one-to-one corresponds to the fourth groove3016. The plate313is fixed to the bottom surface of the fifth groove3022.

The ball314is arranged between the first plate312and the second plate313. Multiple first plates312, multiple second plates313and multiple balls314are provided. The multiple first plates312, multiple second plates313and multiple balls314are in one-to-one correspondence, so as to provide a balanced and evenly distributed support force to prevent the first movable part301from tilting during movement. One end of the ball314close to the first movable part301extends into the fourth groove3016and is in rolling connection with the first plate312, and one end of the ball314close to the first fixed part302extends into the fifth groove3022and is in rolling connection with the second plate313, so that the first movable part301can reciprocate in a plane orthogonal to the direction of the optical axis500.

By accommodating the ball314in the fourth groove3016and the fifth groove3022, the movement of the ball314can be limited, so as to prevent the excessive movement of the first movable part301. There is an overlapping area between the projection of the ball314in the direction of the optical axis500and the first movable part301and the first fixed part302, so that the thicknesses of the first movable part301, the first fixed part302and the thickness of the ball314are overlapped, thereby reducing the occupied space of the ball314and thus is beneficial for the miniaturization of the camera device10and the improvement of the protective effect against the impact of falling.

Further, as shown inFIG.5, a third protrusion3017is protruded from the light-receiving side of the first movable part301in the direction of the optical axis500. In some embodiments, multiple third protrusions3017are provided, and third protrusions3017are arranged on the first movable part301at annular intervals, so as to provide balanced and dispersed buffering and supporting. Those skilled in the art can understand that, the number and distribution of the third protrusions3017can be determined according to the actual situation, which is not limited herein. A first shockproof buffer311is optionally a shock-absorbing gel, which can achieve more accurate anti-shake function by producing shock-absorbing effect for the sudden power-on pulse control of the anti-shake mechanism300.

Further, the optical imaging part and the anti-shake structure300are detachably abutted along the direction of the optical axis500. The motion driven by the driving mechanism400of the optical imaging part and the motion driven and guided by the anti-shake structure300will not interfere or influence each other. Therefore, the anti-shake structure300according to the present disclosure can be freely combined with optical imaging parts of various structures and different driving modes.

In some embodiments, as shown inFIG.1, the first flexible conductive substrate308is equipped with a first position detection element310capable of detecting the magnetic flux of the first magnet307. Optionally, at least two first position detection elements310are provided. By detecting the magnetic flux of the first magnet307, accurate position detection and anti-shake control can be performed for the first movable part301.

According to the technical solutions of the above-mentioned embodiments, the purpose of realizing a more efficient anti-shake mechanism300in the portable electronic device with the characteristic of miniaturization can be achieved, and the quality of the captured image can be improved.

Referring toFIGS.1,5and9, the optical imaging part is an auto-focusing lens structure, and the driving mechanism400includes a second movable part401, a second fixed part402, an elastic support part405and a second coil403. The second movable parts401can reciprocate along the direction of the optical axis500, and both the lens200and the second coil403are connected to the second movable part401.

A cylindrical through groove runs through the middle portion of the second movable part401. The lens200is fixed on the inner circumferential surface of the through groove by bonding, screwing or by other connection manners. The second coil403is an air-core coil that is energized during focusing. When observing along the direction of the optical axis500, the second coil403is a polygon structure, such as a quadrilateral structure. The second coil403is wrapped around the outer wall surface of the second movable part401. When observing along the direction of the optical axis500, the second fixed part402is a square frame structure, and the second movable part401extends into the frame of the second fixed part402. The second magnets404are arranged on the inner wall surface of the second fixed part402, and the second magnets404are arranged around the second coil403.

Two ends of the elastic support part405are connected to the second movable part401and the second fixed part402, respectively, so as to suspend the second movable part401in the accommodation cavity100a. Through their respective elasticity, the lens200is kept in the suspended state with the application of electromagnetic force.

In some embodiments, the elastic support part405includes an upper leaf spring4051and a lower leaf spring4052. The upper leaf spring4051is located on the side of the second movable part401close to the light-receiving side in the direction of the optical axis500. The two ends are respectively connected with the upper end surfaces of the second movable part401and the second fixed part402. The upper end surfaces of the second movable part401and the second fixed part402are provided with several positioning protrusions, and the upper leaf spring4051is provided with positioning through grooves matching with the positioning protrusions. Similarly, the lower leaf spring4052is located on the side of the second movable part401away from the light-receiving side in the direction of the optical axis500. The lower leaf spring4052is arranged opposite to the upper leaf spring4051. Two ends of the lower leaf spring4052are respectively connected with the lower end surfaces of the second movable part401and the second fixed part402. The lower end surfaces of the second movable part401and the second fixed part402are provided with several positioning protrusions, and the lower leaf spring4052is provided with positioning through grooves matching with the positioning protrusions.

The working principle of the above-mentioned driving mechanism400is as follows: the second coil403is energized, and through the interaction between the magnetic field of the second magnet404and the current flowing in the second coil403, a Lorentz force is generated in the second coil403. The direction of the Lorentz force is a direction orthogonal to the direction of the magnetic field of the second magnet404and the direction of the current flowing in the second coil403. Since the second magnet404is fixed, a reaction force acts on the second coil403. This reaction force becomes the driving force of the second movable part401, and the second movable part401having the second coil403moves in the direction of the optical axis500to perform focusing.

Further, referring toFIG.1andFIG.5, the driving mechanism400is further provided with a second flexible conductive substrate407. The second flexible conductive substrate407is equipped with a second position detection element406capable of detecting the magnetic flux of the second magnet. By detecting the magnetic flux of the second magnet404, accurate position detection and focus control can be performed on the lens200. The second coil403, the signal lines and the power lines of the second position detection element406can be arranged at the outside of the driving mechanism400through the second flexible conductive substrate407. Optionally, the second flexible conductive substrate407is integrated with the first flexible conductive substrate308. Furthermore, when a driving integrated circuit is mounted on the first flexible conductive substrate308, energization for driving the movement of the lens200, servo control for feeding back the signal of the second position detection element406can be performed.

Further, as shown inFIG.1, the second movable part401is provided with a second shockproof buffer408, and the second shockproof buffer408is optionally a shock-absorbing gel, which can achieve more accurate anti-shake function by producing shock-absorbing effect for the sudden power-on pulse control of the lens200.

In the related art, there is a further technical problem that is as the size of the imaging assembly increases, the heat generation increases. In the anti-shake mechanism300for shockproof of the imaging assembly, the heat dissipation becomes a problem. There may be a case where the movement is restricted and the elements are damaged due to the heat generation of the imaging assembly itself. In order to solve the technical problem of heat dissipation of the imaging assembly, at least a part of the housing100is made of a metal material with high thermal conductivity, and this part is optionally arranged adjacent to the photosensitive sensor304, for example, located on the bottom wall102, or the bottom wall102is made of metal as a whole. The accommodation cavity100ais provided with a thermal conductive member309, and the thermal conductive member309is in contact with the photosensitive sensor304and the housing100, to conduct the heat of the photosensitive sensor304to the housing100.

Therefore, there is no need to adopt a new heat dissipation structure or use more components such as a fan for air circulation for heat dissipation, so this embodiment has the technical advantages of reducing damage of the photosensitive sensor304, performing good heat dissipation effect, and achieving miniaturization.

In some embodiments, the thermal conductive member309is a heat dissipation gel, which can efficiently transfer the heat emitted from the photosensitive sensor304to the housing100, and can achieve more accurate anti-shake function by producing shock-absorbing effect for the sudden power-on pulse control of the anti-shake mechanism300. Those skilled in the art may understand that the thermal conductive member309also has other implementing manners, which are not listed herein.

The optical imaging part of the foregoing embodiments is an auto-focusing lens structure. In some embodiments, as shown inFIG.12, the above-mentioned anti-shake mechanism300can also be applied to the optical imaging part of a periscope lens structure600. The lens structure600further includes a first prism601on the object side of the lens200and/or a second prism602on the image side of the lens200. The first prism601and the second prism602are configured to change the direction of the light path. By arranging the first prism601and/or the second prism602capable of changing the optical path, it is beneficial to reduce the volume of the camera device, thereby facilitating the miniaturization and portability of the camera device.
