Description

[0001] This application claims priority to Japanese Patent Application No. 2022-059566, filed with the Japan Patent Office on March 31, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of camera device technology, and more particularly to a drive mechanism, camera device, and portable electronic device. Background Technology

[0003] With the rapid development of shooting technology, camera devices with lens-driven mechanisms are widely used in many shooting devices. The application of camera devices with lens-driven mechanisms to various portable electronic devices such as mobile phones and tablet computers has been accepted by consumers.

[0004] The drive mechanism of lens drive devices used in typical portable electronic devices usually includes an autofocus mechanism that adjusts the focus in the optical axis direction and an image stabilization mechanism that drives the lens in a plane orthogonal to the optical axis direction.

[0005] In existing drive mechanisms, the mover of the autofocus mechanism carries the lens and accompanies it in autofocusing along the optical axis and in image stabilization along a plane perpendicular to the optical axis. To suppress unwanted vibrations generated during autofocusing, an autofocus damping gel can be applied between the mover and stator of the autofocus mechanism. However, to avoid affecting the image stabilization, this autofocus damping gel is usually not applied between the mover and the housing of the drive mechanism, but only inside the autofocus mechanism. This means that the amount of autofocus damping gel can only be determined during the assembly of the drive mechanism, and the amount of autofocus damping gel cannot be adjusted when testing the autofocus drive sensitivity after the entire drive mechanism is assembled.

[0006] Therefore, it is necessary to provide a new drive mechanism to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a drive mechanism, a camera device, and a portable electronic device, which allows for adjustment of the amount of damping gel used for autofocus after the drive mechanism is assembled.

[0008] The technical solution of the present invention is as follows: A driving mechanism is provided, including an autofocus mechanism and an image stabilization mechanism. The autofocus mechanism can accommodate a lens and drive the lens along the optical axis of the lens. The autofocus mechanism includes an autofocus stator and an autofocus mover movable relative to the autofocus stator. The autofocus mover includes an autofocus bracket for mounting the lens. The image stabilization mechanism can accommodate a camera element assembly and drive the camera element assembly in a plane perpendicular to the optical axis of the lens. The image stabilization mechanism and the autofocus mechanism are arranged along the optical axis of the lens. The image stabilization mechanism includes an image stabilization mechanism stator and an image stabilization mover movable relative to the image stabilization mechanism. A stabilizing mechanism mover is configured to move via a stator and is located on the side of the stabilizing mechanism stator closer to the autofocus mechanism. The stabilizing mechanism mover includes a stabilizing mechanism movable frame spaced apart from the autofocus mover. The movable frame is used to mount the camera element assembly. The autofocus bracket has a groove on its surface facing the autofocus stator. The groove is coated with autofocus damping gel. The autofocus stator has a claw member extending toward the groove, which can extend into the groove and engage with the autofocus damping gel. The autofocus stator also has a through hole opposite the groove to expose the groove.

[0009] In one possible design, the autofocus bracket is provided with a plurality of grooves at intervals, and the autofocus stator is provided with a plurality of claw members corresponding to the grooves.

[0010] In one possible design, the autofocus housing is further provided with a claw member, the surface of the autofocus bracket for setting the groove is perpendicular to the optical axis of the lens, and at least a portion of the claw member extends along the optical axis of the lens.

[0011] In one possible design, the claw member includes a claw member root connected to the wall of the through hole and a claw member pin extending from the claw member root. The claw member root is arc-shaped, and the claw member pin is a flat plate extending along the optical axis of the lens.

[0012] In one possible design, the autofocus stator includes an autofocus housing, the image stabilization stator includes an image stabilization housing, the autofocus housing and the image stabilization housing are closed to form a receiving space, and the autofocus mover and the image stabilization mover are received within the receiving space.

[0013] In one possible design, the autofocus housing includes a top wall perpendicular to the optical axis of the lens and a light-transmitting hole formed in the top wall, the through hole being formed in the top wall and communicating with the light-transmitting hole.

[0014] In one possible design, the top wall of the autofocus housing is quadrilateral, and the claw members are disposed at the four corners of the top wall.

[0015] In one possible design, a first damping gel for the image stabilization mechanism is provided between the stator and the mover of the image stabilization mechanism; and a second damping gel for the image stabilization mechanism is provided between the mover and the stator for autofocus.

[0016] The second technical solution adopted by the present invention is: to provide a camera device, the camera device including the driving mechanism described above and the lens and the camera element assembly housed in the driving mechanism, the camera element assembly including a filter and a circuit board equipped with an image sensor, the image stabilization mechanism of the driving mechanism using a movable frame including a main body for mounting the filter and a cantilever extending vertically from the main body, the circuit board being fixed to the cantilever.

[0017] The third technical solution adopted by the present invention is to provide a portable electronic device, which includes the camera device described above.

[0018] The beneficial effects of this invention are as follows: the autofocus mover and the anti-shake mechanism mover are independent of each other. By setting the autofocus damping gel between the autofocus mover and the autofocus stator, vibration in the optical axis direction can be suppressed without affecting the movement of the anti-shake mechanism mover. At the same time, the autofocus stator is provided with a through hole that exposes the groove containing the autofocus damping gel. After the drive mechanism is assembled, the autofocus damping gel can be added or removed into the groove through the through hole to adjust the autofocus damping gel, thereby improving the damping effect of the autofocus mechanism.

[0019] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention. Attached Figure Description

[0078] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention. Detailed Implementation

[0079] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0080] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0081] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0082] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of the present invention are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of the present invention. Furthermore, in the context, it should be understood that when referring to an element being connected "upper" or "lower" to another element, this can mean not only that it can be directly connected to the other element "upper" or "lower," but also that it can be indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0083] like Figures 1 to 10As shown, the present invention provides a driving mechanism including an autofocus mechanism 20A and an image stabilization mechanism 10A. The autofocus mechanism 20A can accommodate a lens 1 and drive the lens 1 along the optical axis direction X of the lens 1. The image stabilization mechanism 10A can accommodate an image sensor assembly 5 and drive the image sensor assembly 5 in a plane perpendicular to the optical axis direction X of the lens 1. The image stabilization mechanism 10A is disposed on the image side of the lens 1 and is arranged with the autofocus mechanism 20A along the optical axis direction X of the lens 1.

[0084] The autofocus mechanism 20A includes an autofocus stator and an autofocus mover that can move relative to the autofocus stator. The image stabilization mechanism 10A includes an image stabilization mechanism stator and an image stabilization mechanism mover that can move relative to the image stabilization mechanism stator.

[0085] The autofocus stator includes an autofocus housing 2, and the anti-shake mechanism stator includes an anti-shake mechanism housing 3. The autofocus housing 2 and the anti-shake mechanism housing 3 are located at both ends of the drive mechanism and are covered to form a receiving space. The autofocus mover and the anti-shake mechanism mover are both received in the receiving space.

[0086] The autofocus actuator includes an autofocus bracket 21 for mounting the lens 1. The autofocus bracket 21 can move the lens 1 along the optical axis X to achieve focus adjustment. The image stabilization actuator includes a movable frame 11 for mounting the image sensor assembly 5. The movable frame 11 can move the image sensor assembly 5 in a plane perpendicular to the optical axis X to achieve optical image stabilization. The autofocus bracket 21 and the movable frame 11 are spaced apart along the optical axis X. Therefore, in this embodiment, the autofocus actuator and the image stabilization actuator can move independently without interfering with each other.

[0087] In this embodiment, the autofocus bracket 21 has a groove 21-1 on its surface facing the autofocus stator. The groove 21-1 is coated with an autofocus damping gel 31. The autofocus stator is provided with a claw member 4 extending toward the groove 21-1. The claw member 4 can extend into the groove 21-1 and cooperate with the autofocus damping gel 31 to generate damping that suppresses vibration in the X direction of the optical axis.

[0088] In this embodiment, the stator for autofocusing is also provided with a through hole 2-1-1 opposite to the groove 21-1 so that the groove 21-1 is exposed, that is, the groove 21-1 can be touched from the outside of the stator for autofocusing. After the drive mechanism is assembled, the autofocusing damping gel 31 can be added or removed into the groove 21-1 through the through hole 2-1-1 to adjust the autofocusing damping gel 31, thereby adjusting the damping effect of the autofocusing mechanism 20A.

[0089] In this embodiment, the autofocus stator further includes an autofocus base 20 and an autofocus magnet 24, and the autofocus mover includes at least an autofocus bracket 21 and an autofocus coil 25. The lens 1 and the autofocus coil 25 are both connected to the autofocus bracket 21. The lens 1 is fixed to the circular hole at the center of the autofocus bracket 21, and the autofocus coil 25 is sleeved on the outer wall of the autofocus bracket 21. The autofocus base 20 is a frame structure sleeved on the autofocus bracket 21, and the autofocus magnet 24 is fixed to the inner wall of the autofocus base 20, spaced apart from the autofocus coil 25.

[0090] When the autofocus mechanism 20A performs autofocus, the autofocus coil 25 is energized. Through the interaction between the magnetic field of the autofocus magnet 24 and the current flowing through the autofocus coil 25, a driving force is generated that can drive the autofocus mover to move relative to the autofocus stator along the optical axis X of the lens 1. This drives the lens 1, which is fixed on the autofocus bracket 21, to move. By controlling the direction and magnitude of the current flowing into the autofocus coil 25, the position of the lens 1 can be adjusted to achieve focus adjustment.

[0091] Furthermore, such as Figure 1 As shown in the embodiment, the autofocus mechanism 20A also includes an autofocus-conducting flexible substrate 26, an autofocus-conducting position detection element 27, and an autofocus-conducting position detection magnet 28. The autofocus-conducting position detection magnet 28 is disposed on the autofocus-conducting bracket 21, and the autofocus-conducting flexible substrate 26 is equipped with the autofocus-conducting position detection element 27, which can detect the magnetic flux of the autofocus-conducting position detection magnet 28 moving along the optical axis direction X of the lens 1, thereby performing accurate position detection and autofocus control.

[0092] The autofocus mechanism 20A also includes an upper autofocus spring 22 and a lower autofocus spring 23. The two ends of the autofocus bracket 21 are connected to the upper autofocus spring 22 and the lower autofocus spring 23 respectively. Both the upper autofocus spring 22 and the lower autofocus spring 23 are elastic and can keep the lens 1 in a suspended state without the application of electromagnetic force.

[0093] During the operation of the drive mechanism, the elasticity of the upper leaf spring 22 and the lower leaf spring 23 for autofocus will cause the autofocus mechanism 20A to generate vibrations in the optical axis direction X of the lens 1 that affect the focusing effect. However, since the present invention provides an autofocus damping gel 31 between the autofocus bracket 21 and the autofocus stator, the vibration can be suppressed.

[0094] In one specific embodiment, such as Figure 2 and Figures 4 to 7 As shown, the autofocus bracket 21 has a groove 21-1 on one surface facing the autofocus stator, and this surface is perpendicular to the optical axis X of the lens 1. An autofocus damping gel 31 is disposed within the groove 21-1. The autofocus stator has a through hole 2-1-1 corresponding to the groove 21-1, which connects to the outside and the groove 21-1. At least a portion of the claw member 4 extends through the through hole 2-1-1 into the interior of the groove 21-1 along the optical axis X of the lens 1, cooperating with the autofocus damping gel 31 to generate a damping effect.

[0095] like Figure 4 As shown in the embodiment, the autofocus bracket 21 is provided with a plurality of grooves 21-1 at intervals, and the autofocus stator is provided with a plurality of through holes 2-1-1 corresponding to the grooves 21-1 and a claw member 4, so that the shock absorption capability of the autofocus mechanism 20A is further improved.

[0096] In one specific embodiment, such as Figure 6 As shown, the claw component 4 includes a claw component root 4-1 connected to the wall of the through hole 2-1-1 and a claw component pin 4-2 extending from the claw component root 4-1. The claw component root 4-1 is arc-shaped, and the claw component pin 4-2 is a flat plate extending along the optical axis X of the lens 1. In this embodiment, the claw component 4 has a simple structure and is easy to manufacture.

[0097] In one specific embodiment, such as Figure 6 and Figure 7 As shown, the autofocus housing 2 includes a top wall 2-1 perpendicular to the optical axis X of the lens 1 and a light-transmitting hole 2-1-2 opened in the top wall 2-1. The through hole 2-1-1 is opened in the top wall 2-1 and communicates with the light-transmitting hole 2-1-2.

[0098] In this embodiment, the light-transmitting hole 2-1-2 is located in the middle of the autofocus housing 2 and is used to accommodate the lens 1. Light enters the lens 1 through the light-transmitting hole 2-1-2. When the autofocus mechanism 20A performs autofocus, the autofocus bracket 21 can drive the lens 1 to move along the optical axis X of the lens 1 within the light-transmitting hole 2-1-2. The connection between the through hole 2-1-1 and the light-transmitting hole 2-1-2 simplifies the structure of the autofocus housing 2.

[0099] like Figure 2 As shown, the top wall 2-1 of the automatic focusing housing 2 is quadrilateral, and the claw members 4 are located at the four corners of the top wall 2-1, which can maintain the force balance of the automatic focusing mechanism 20A during the movement.

[0100] In one specific embodiment, the stator for the image stabilization mechanism further includes an image stabilization mechanism base 10 and an image stabilization mechanism magnet 17, while the mover for the image stabilization mechanism includes an image stabilization mechanism circuit board 16 and an image stabilization mechanism coil 16-1 embedded in the image stabilization mechanism circuit board 16. The image stabilization mechanism magnet 17 is fixed to the image stabilization mechanism base 10, and the image stabilization mechanism circuit board 16 and the camera element assembly 5 are both fixed to the movable frame 11 of the image stabilization mechanism. The image stabilization mechanism coil 16-1 and the image stabilization mechanism magnet 17 are arranged at intervals relative to each other along the optical axis X of the lens 1.

[0101] When the image stabilization mechanism 10A performs image stabilization correction, the coil 16-1 of the image stabilization mechanism is energized. Through the interaction between the magnetic field of the magnet 17 of the image stabilization mechanism and the current flowing through the coil 16-1, a movable frame 11 of the image stabilization mechanism is driven to move in a plane orthogonal to the optical axis X of the lens 1, thus completing the image stabilization correction. By controlling the direction and magnitude of the current flowing through the coil 16-1, the angle and amplitude of the movement of the movable frame 11 can be controlled, enabling the drive mechanism to achieve the image stabilization effect.

[0102] Specifically, such as Figure 1 , Figure 8 and Figure 9 As shown, in one application, the camera element assembly 5 includes a filter 5-1 and a circuit board 5-2 on which an image sensor 5-3 is mounted. The movable frame 11 for the image stabilization mechanism includes a main body 11-1 on which the filter 5-1 is mounted and a cantilever 11-2 extending vertically from the main body. The circuit board 5-2 is fixed to the cantilever 11-2.

[0103] The filter 5-1 is used to block harmful wavelengths of infrared light to protect the image sensor 5-3. Both the filter 5-1 and the circuit board 5-2 on which the image sensor 5-3 is mounted are set on the movable frame 11 of the image stabilization mechanism. This reduces the number of components in the image stabilization mechanism 10A, which is beneficial to the miniaturization of the image stabilization mechanism 10A. It also improves the perpendicularity of the image sensor 5-3 to the optical axis X of the lens 1 and reduces the possibility of deviations during the installation process.

[0104] like Figure 1 As shown, the image stabilization mechanism also includes a magnetic yoke 12 disposed on the movable frame 11 of the image stabilization mechanism. The magnetic yoke 12 is located on the side of the coil 16-1 of the image stabilization mechanism near the autofocus mechanism 20A. The magnetic yoke 12 can work together with the magnet 17 of the image stabilization mechanism to ensure that the movable frame 11 of the image stabilization mechanism always moves in a plane orthogonal to the optical axis X of the lens 1, thereby reducing the tilt of the image sensor assembly 5 relative to the optical axis. In this invention, the magnetic yoke 12 of the image stabilization mechanism can also reduce magnetic leakage to increase the magnetic flux through the coil 16-1 of the image stabilization mechanism, thereby increasing the driving force.

[0105] In one specific embodiment, at least two position detection elements 16-2 for the anti-shake mechanism can be provided on the circuit board 16 for the anti-shake mechanism. By detecting the magnetic flux of the fixed magnet 17 for the anti-shake mechanism, correct position detection and anti-shake control can be performed.

[0106] In one specific embodiment, such as Figure 1 As shown, the image stabilization mechanism 10A also includes a support plate (for movable frame) 13 for the image stabilization mechanism support member and a support plate (for base) 15 for the image stabilization mechanism support member. Along the optical axis X of the lens 1, an image stabilization mechanism support member 14 is provided between the support plate (for movable frame) 13 for the image stabilization mechanism support member and the support plate (for base) 15 for the image stabilization mechanism support member. The image stabilization mechanism support member 14 can be a sphere, which can reduce the resistance between the movable frame 11 for the image stabilization mechanism and the base 10 for the image stabilization mechanism during the movement, reduce the force required to drive the movable frame 11 for the image stabilization mechanism, and make the movement of the movable frame 11 for the image stabilization mechanism more convenient. By adjusting the surface accuracy of the support plate (movable frame) 13 and the support plate (base) 15 of the support member for the anti-shake mechanism, the friction between the support member 14 of the anti-shake mechanism and the support plate (movable frame) 13 and the support plate (base) 15 of the support member for the anti-shake mechanism can be reduced, thereby enabling the support member 14 of the anti-shake mechanism to slide more smoothly.

[0107] In one specific embodiment, such as Figure 10 As shown, the image stabilization mechanism 10A also includes a flexible substrate 18 for image stabilization. The flexible substrate 18 is electrically connected to the circuit board 16 for image stabilization. Current can be passed through the flexible substrate 18 to the coil 16-1 for image stabilization, thereby driving the movable frame 11 for image stabilization to move along the X-axis direction perpendicular to the optical axis of the lens 1 to achieve the effect of stabilizing hand shake. The coil 16-1 for image stabilization and the signal lines and power lines of the camera element assembly 5 can be embedded in the flexible substrate 18 for image stabilization, thus being arranged on the outside of the movable frame 11 for image stabilization, without hindering the operation of the image stabilization mechanism 10A.

[0108] Specifically, the flexible substrate 18 for the image stabilization mechanism can be configured to include at least a curved surface A18-1 and a curved surface B18-2 of the flexible substrate for the image stabilization mechanism.

[0109] In addition, the autofocus mechanism 20A is also provided with an autofocus-powered flexible substrate 26 connected to the flexible substrate 18 for the image stabilization mechanism. The autofocus-powered flexible substrate 26 is located on the outside of the autofocus mechanism 20A and can be integrated with the flexible substrate 18 for the image stabilization mechanism. When a driver integrated circuit is mounted on the flexible substrate 18 for the image stabilization mechanism, it is possible to perform servo control such as powering on autofocus and feeding back signals from the position detection element for autofocus.

[0110] In one specific embodiment, a first damping gel 30 for the anti-shake mechanism is disposed between the stator and the mover of the anti-shake mechanism, such as... Figure 1 As shown, the first damping gel 30 for the image stabilization mechanism is disposed on the side of the housing 3 of the image stabilization mechanism near the camera element assembly 5. The base 10 of the image stabilization mechanism is provided with a clearance hole through which the first damping gel 30 can pass. When the coil 16-1 of the image stabilization mechanism is suddenly energized, the first damping gel 30 has a damping effect on the vibration generated by the camera element assembly 5, so that the image stabilization mechanism 10A has a more accurate image stabilization function.

[0111] A second damping gel 32 for the image stabilization mechanism is provided between the mover of the image stabilization mechanism and the stator of the autofocus mechanism, such as... Figure 1 As shown, the second damping gel 32 for the image stabilization mechanism is disposed on the side surface of the movable frame 11 of the image stabilization mechanism facing the autofocus mechanism 20A, and abuts against the side surface of the autofocus base 20 facing the image stabilization mechanism 10A. When the drive mechanism is subjected to impact from the external environment or when the movable frame 11 of the image stabilization mechanism experiences sudden vibration, the second damping gel 32 for the image stabilization mechanism can play a damping role, reducing the risk of damage to the autofocus mechanism 20A and the image stabilization mechanism 10A.

[0112] In this invention, the components of the autofocus mechanism 20A and the image stabilization mechanism 10A are separated and their inherent vibrations are suppressed, thus reducing the design difficulty. At the same time, it is not necessary to move the lens 1 in three dimensions, which reduces the difficulty of designing shock resistance during drops, and correspondingly, centering the lens 1 becomes easier.

[0113] This invention also provides a camera device 100, including the driving mechanism described in the above embodiments, and a lens 1 and a camera element assembly 5 housed within the driving mechanism.

[0114] This invention also provides a portable electronic device 200, such as... Figure 11 As shown, the camera device 100, including the driving mechanism described in the above embodiments, can be used in the portable electronic device 200. The portable electronic device 200 can be a smartphone, feature phone, or tablet, etc.

[0115] Since the lens 1 only moves along the optical axis X of the lens 1 and there is no movement in the plane, the opening for the lens 1 to protrude in the portable electronic device 200 such as a smartphone can be minimized.

[0116] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
