Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a camera module and an electronic device. Background Technology

[0002] In related technologies, as smart terminal products are constantly being innovated, their functions and the user experience they provide are also continuously evolving. Among these, photo quality is crucial for enhancing the value of smart terminal products. However, camera shake during shooting affects the final image quality, especially in scenarios where users hold the smart terminal to take photos, where the image quality is easily affected by hand tremors, often resulting in blurry photos. Related technologies use voice coil motors to drive lens movement for image stabilization, but the tilt angle for this stabilization is limited. Summary of the Invention

[0003] This application aims to provide a camera module and electronic device that at least solves the problem of limited tilt angle for image stabilization when the lens is driven by a voice coil motor.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application propose a camera module, comprising: a bracket assembly including a sleeve having an opening, the sleeve having a first slide rail on its inner wall surface; a lens movably disposed within the sleeve and exposed through the opening, the lens having a second slide rail on its outer wall surface, the second slide rail being arranged circumferentially along the lens; at least two connectors located between the lens and the sleeve, a portion of the connectors being disposed within the first slide rail and capable of sliding within the first slide rail, and a portion of the connectors being disposed within the second slide rail and capable of sliding within the second slide rail, the at least two connectors being used to adjust the tilt angle of the lens relative to the sleeve, wherein, along the axial direction of the sleeve, at least one of the first slide rail and the second slide rail is bent.

[0006] Secondly, embodiments of this application provide an electronic device, including: a camera module as described in any of the first aspects.

[0007] In the embodiments of this application, the camera module includes a support assembly, a lens, and at least two connectors. The support assembly includes a sleeve, with the lens movably disposed within the sleeve. A first slide rail is provided within the sleeve, and a second slide rail is provided on the outer wall of the lens. At least two connectors are disposed between the first and second slide rails, with a portion of the connector corresponding to a part of the sleeve extending into the first slide rail and a portion of the connector corresponding to a part of the lens extending into the second slide rail. The connectors are slidable within the first and second slide rails respectively. At least one of the first and second slide rails is bent along the axial direction of the sleeve, resulting in a height difference between the at least two connectors along the axial direction of the sleeve when the at least two connectors move along the first and second slide rails. Thus, when the camera module shakes, the at least two connectors can adjust the tilt angle of the lens through the different height differences, thereby balancing the shake, achieving image stabilization, and improving the shooting effect. Furthermore, the camera module proposed in this application, by setting the first and second slide rails, achieves lens tilt, which is not limited by the drive mechanism, thereby expanding the adjustment of the tilt angle and improving the image stabilization effect.

[0025] The following is combined with Figures 1-9 This application describes a camera module 1 and an electronic device according to embodiments thereof.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, a camera module 1 according to some embodiments of this application includes: a bracket assembly 2, the bracket assembly 2 including a sleeve 20 having an opening 202, and a first slide rail 204 provided on the inner wall surface of the sleeve 20; a lens 3, the lens 3 being movably disposed within the sleeve 20 and being exposed through the opening 202, and a second slide rail 30 provided on the outer wall surface of the lens 3, the second slide rail 30 being disposed along the circumference of the lens 3; at least two connectors 4, located between the lens 3 and the sleeve 20, a portion of the connectors 4 being disposed within the first slide rail 204 and being slidable within the first slide rail 204, and a portion of the connectors 4 being disposed within the second slide rail 30 and being slidable within the second slide rail 30, the at least two connectors 4 being used to adjust the tilt angle of the lens 3 relative to the sleeve 20, wherein, along the axial direction of the sleeve 20, at least one of the first slide rail 204 and the second slide rail 30 is bent.

[0027] In the embodiments of this application, the camera module 1 includes a bracket assembly 2, a lens 3, and at least two connectors 4. The bracket assembly 2 includes a sleeve 20, the lens 3 is movably disposed within the sleeve 20, a first slide rail 204 is disposed within the sleeve 20, a second slide rail 30 is disposed on the outer wall surface of the lens 3, and at least two connectors 4 are disposed between the first slide rail 204 and the second slide rail 30. A portion of the connector 4 corresponding to a part of the sleeve 20 extends into the first slide rail 204, and a portion of the connector 4 corresponding to a part of the lens 3 extends into the second slide rail 30. The connectors 4 are slidable within the first slide rail 204 and the second slide rail 30, respectively. At least one of the first slide rail 204 and the second slide rail 30 is bent along the axial direction of the sleeve 20, resulting in a height difference between the at least two connectors 4 along the axial direction of the sleeve 20 when the connectors 4 move along the first slide rail 204 and the second slide rail 30. In this way, when the camera module 1 shakes, at least two connecting parts 4 can adjust the tilt angle of the lens 3 through different height differences, thereby balancing the shaking and achieving the image stabilization function of the lens 3, thus improving the shooting effect. Meanwhile, the camera module proposed in this application, by setting the first slide rail 204 and the second slide rail 30, achieves the tilt of the lens 3, which is not limited by the drive mechanism, thereby expanding the adjustment of the tilt angle and improving the image stabilization effect.

[0028] Furthermore, the first slide rail 204 is curved, and the second slide rail 30 is annular. The second slide rail 30 is rigidly connected to the outer wall of the lens 3, for example, the second slide rail 30 is bonded to the outer wall of the lens 3 by an adhesive.

[0029] In practical applications, when the camera module 1 shakes, the control device 6 generates a signal to resist the shaking. At least two connecting pieces 4 move in the first slide rail 204 and the second slide rail 30 under the action of the control device 6. With at least two connecting pieces 4 in different positions and at different heights of tilt, the lens 3 is tilted, thereby achieving the effect of image stabilization.

[0030] Along the circumference of the sleeve 20, any connector 4 can slide along the first slide rail 204 and the second slide rail 30. The arrangement of at least two connectors 4 can form different height differences according to the bending of at least one of the first slide rail 204 and the second slide rail 30 when shaking occurs, thereby achieving the tilting of the lens 3 under the action of at least two connectors 4.

[0031] like Figure 7 As shown, according to some embodiments of this application, the camera module 1 further includes: a detection unit 5, which is used to detect the shaking signal of the lens 3; a control device 6, connected to the detection unit 5, which is used to determine the target position of the connector 4 in the first slide rail 204 or the second slide rail 30 according to the shaking signal; and a drive member 7, connected to the control device 6, which drives the connector 4 to rotate circumferentially along the sleeve 20 according to the target position to adjust the tilt angle.

[0032] In this embodiment, the camera module 1 further includes a detection unit 5, a control device 6, and a drive unit 7. The detection unit 5 can detect the shaking signal of the lens 3. The control device 6 determines the target position of the connector 4 based on the shaking signal detected by the detection unit 5. Then, the control device 6 controls the drive unit 7 to drive the connector 4 to move to the target position, so that the lens 3 tilts to resist the shaking and realize the image stabilization function of the lens 3.

[0033] In a specific application, the control device 6 generates a motion signal that can resist the shaking signal based on the shaking signal generated by the camera module 1, determines the target position of at least two connectors 4 based on the motion signal, and then controls the drive unit 7 to drive at least two connectors 4 to move so that at least two connectors 4 move to the target position, thereby realizing the image stabilization of the camera module 1.

[0034] It is understandable that when at least two connectors 4 are in the target position, the tilt angle of the lens 3 is offset by the tilt angle caused by the shaking of the camera module 1, thereby achieving image stabilization of the lens 3.

[0035] like Figure 3 and Figure 4As shown, according to some embodiments of this application, the driving component 7 includes: a plurality of piezoelectric ceramic components 70 disposed in the first slide rail 204 or the second slide rail 30; and contacts 71 disposed in the connector 4, with the contacts 71 corresponding to the piezoelectric ceramic components 70, and the piezoelectric ceramic components 70 driving the connector 4 to move through the contacts 71.

[0036] In this embodiment, the driving component 7 includes a plurality of piezoelectric ceramic components 70, which are disposed in the first slide rail 204 or the second slide rail 30. The connecting component 4 is provided with a contact 71, which is correspondingly disposed with the piezoelectric ceramic component 70. After the control device 6 determines the target position, it transmits a signal to the piezoelectric ceramic component 70. The contact 71 is driven by the piezoelectric ceramic component 70 to slide along the first slide rail 204 and the second slide rail 30, thereby causing the lens 3 to tilt to resist shaking.

[0037] In addition, the piezoelectric ceramic component 70 is small in size and has a simple structure, which is beneficial for the miniaturization design of the camera module 1.

[0038] Furthermore, the piezoelectric ceramic component 70 is a piezoelectric ceramic motor, which can drive the connector 4 to move circumferentially along the sleeve.

[0039] That is, this application achieves image stabilization of the camera module 1 by setting a first slide rail 204 on the sleeve 20, setting a second slide rail 30 on the lens 3, and connecting the two with a connector 4. When the electronic device shakes while taking a picture, the control device 6 generates a signal to resist the shaking. The piezoelectric ceramic component 70 inside the sleeve 20 converts the signal and drives the connector 4 to move. This causes the connector 4 to rotate along the specially designed first slide rail 204 in the sleeve 20, causing the lens 3 to tilt, thereby achieving a specific tilt angle and achieving the effect of image stabilization. Specifically, as shown... Figure 1 As shown, by driving at least two connecting parts 4 to move, the lens 3 rotates around the X-axis by an angle α, where, Figure 1 The X-axis shown is set perpendicular to the plane of the paper. For example... Figure 2 As shown, by driving at least two connecting parts 4 to move, the lens 3 rotates around the Y-axis. The dashed arrow indicates the direction of rotation of the lens 3, and the rotation angle is β (not shown in the figure). Specifically, in a plane perpendicular to the axis of the sleeve 20, the X-axis is perpendicular to the Y-axis.

[0040] It should be noted that in related technologies, the tilt angle of the lens is less than or equal to 1°, while in the embodiments proposed in this application, the rotation angle α of the lens 3 around the X-axis is greater than or equal to 2° and less than or equal to 3°, and the rotation angle β of the lens 3 around the Y-axis is greater than or equal to 2° and less than or equal to 3°. Therefore, the camera module proposed in this application can improve the anti-shake angle range, thereby improving the camera effect.

[0041] In one possible design, with the first slide rail 204 bent along the axial direction of the sleeve 20, the piezoelectric ceramic element 70 is disposed within the first slide rail 204, and the contact 71 is disposed at the end of the connector 4 extending into the first slide rail 204. The piezoelectric ceramic element 70 can drive a connector 4 to move within the first slide rail 204 and the second slide rail 30, and can maintain the position of at least one connector 4 unchanged. That is, different angles of the lens 3 can be adjusted by varying the position of the connector 4 within the first slide rail 204, thus reducing energy consumption. Furthermore, placing the piezoelectric ceramic element 70 within the sleeve 20 facilitates the arrangement of the piezoelectric ceramic element 70's wiring.

[0042] like Figure 3 and Figure 4 As shown, in another possible design, with the first slide rail 204 bent along the axial direction of the sleeve 20, the piezoelectric ceramic element 70 is disposed within the first slide rail 204, and the contact point 71 is disposed at the end of the connector 4 extending into the first slide rail 204. The piezoelectric ceramic element 70 can drive at least two connectors 4 to slide circumferentially within the first slide rail 204 and the second slide rail 30 of the sleeve 20, so that at least two connectors 4 are located in different positions, thereby achieving adjustment of different angles of the lens 3. Because the first slide rail 204 is bent, when at least two connectors 4 can rotate circumferentially under the drive of the piezoelectric ceramic element 70, the rotation angle of the lens 3 can be increased. At the same time, since the structure is simple and occupies little space by driving the connectors 4 through the piezoelectric ceramic element 70, a larger angle adjustment can also be achieved. Furthermore, placing the piezoelectric ceramic element 70 within the sleeve 20 facilitates the arrangement of the piezoelectric ceramic element 70 circuitry.

[0043] Specifically, by adjusting the curvature of the first slide rail 204, a greater tilt angle of the lens 3 can be achieved. Specifically, the sleeve 20 structure is as follows: Figure 3 As shown, the first slide rail 204 is curved. The curve shape of the first slide rail 204 is specially designed. The connector 4 on the lens 3 slides in the first slide rail 204 to achieve a certain angle of tilt of the lens 3, which meets the motion angle requirements of the lens 3 for image stabilization.

[0044] In one possible design, with the piezoelectric ceramic component 70 disposed within the second slide rail 30, the contact 71 is disposed at the end of the connector 4 that extends into the second slide rail 30.

[0045] It should be noted that the piezoelectric ceramic component 70 can drive the connector 4 to rotate circumferentially along the sleeve 20 through the contact 71, thereby moving to different positions and achieving different angles of tilt.

[0046] According to some embodiments of this application, a plurality of piezoelectric ceramic elements 70 are equally spaced within the first slide rail 204 or the second slide rail 30 along the circumference of the sleeve 20.

[0047] In this embodiment, multiple piezoelectric ceramic elements 70 are equally spaced within the first slide rail 204 or equally spaced within the second slide rail 30 along the circumference of the sleeve 20. Thus, under the combined action of the multiple piezoelectric ceramic elements 70, the drive connector 4 can move continuously along the circumference of the sleeve 20, thereby moving the connector 4 to the target position to balance the shaking of the lens 3, achieve the anti-shake function, and improve the anti-shake effect of shooting.

[0048] Of course, the spacing between two adjacent piezoelectric ceramic parts 70 can also be set to be unequal.

[0049] like Figure 8 As shown, according to some embodiments of this application, the driving component 7 includes an electromagnet 72 and a magnet 73. One of the electromagnet 72 and the magnet 73 is disposed in the connecting component 4, and the other is disposed in the first slide rail 204 or the second slide rail 30. The electromagnet 72 is connected to the control device 6, and the control device 6 controls the electromagnet 72 to work according to the target position.

[0050] In this embodiment, the driving component 7 further includes an electromagnet 72 and a magnet 73. The magnetic field between the electromagnet 72 and the magnet 73 drives the connecting component 4 to move, thereby adjusting the tilt angle of the lens 3. Specifically, one of the electromagnet 72 and the magnet 73 is disposed on the connecting component 4, and the other is disposed within the first slide rail 204 or the second slide rail 30. The electromagnet 72 is connected to the control device 6, which controls the current intensity and direction of the electromagnet 72. Under the influence of the magnetic field between the electromagnet 72 and the magnet 73, the connecting component 4 is driven to move to the target position, thus adjusting the tilt angle of the lens 3.

[0051] In practical applications, the electromagnet 72 is installed inside the first slide rail 204 of the sleeve 20, and the magnet 73 is installed on the connector 4 to facilitate the wiring of the electromagnet 72. Under the action of the magnetic field of the electromagnet 72 and the magnet 73, the connector 4 can be driven to rotate circumferentially along the sleeve 20, thereby causing the lens 3 to tilt to adjust the tilt angle of the lens 3.

[0052] Furthermore, each connector 4 is provided with a magnet 73, and multiple electromagnets 72 are provided in the first slide rail 204. Specifically, after the control device 6 determines the target position of the connector 4 based on the jitter signal, it controls the electromagnet 72 corresponding to the target position to be energized, so that it generates an attraction force, thereby attracting the magnet 73 on the corresponding connector 4, causing the connector 4 to move to the target position. When there are two connectors 4, the connectors 4 include a first connector 4 and a second connector 4. Accordingly, the control device 6 determines that the first connector 4 should move to a first position and the second connector 4 should move to a second position to counteract the jitter, based on the jitter signal. In this way, the control device 6 controls the electromagnets 72 at the first position and the second position to be energized, so that the magnet 73 on the first connector 4 is attracted by the electromagnet 72 at the first position and moves to the first position, and the magnet 73 on the second connector 4 is attracted by the electromagnet 72 at the second position and moves to the second position, thereby realizing the movement of the two connectors 4.

[0053] Furthermore, magnet 73 is a permanent magnet.

[0054] like Figure 9 As shown, according to some embodiments of this application, the driving member 7 includes a driving motor 74, which is used to drive the connecting member 4 to slide within the first slide rail 204 and the second slide rail 30.

[0055] In this embodiment, the driving component 7 includes a driving motor 74, which is connected to the connecting component 4 and is used to drive the connecting component 4 to slide within the first slide rail 204 and the second slide rail 30, thereby realizing the adjustment of the tilt angle of the lens 3.

[0056] In a specific application, a drive motor 74 is connected to any connector 4. The control device 6 determines the target position of at least two connectors 4 based on the shaking signal, and then controls the drive motor 74 to drive at least two connectors 4 to move to the corresponding target position according to the target position, thereby realizing the adjustment of the tilt angle of the lens 3.

[0057] like Figure 3 As shown, according to some embodiments of this application, when the first slide rail 204 is bent, the first slide rail 204 includes a plurality of peaks 206 and a plurality of valleys 208, wherein, along the axial direction of the sleeve 20, the distance between the peaks 206 and the openings 202 is less than the distance between the valleys 208 and the openings 202.

[0058] In this embodiment, when the first slide rail 204 is bent, the first slide rail 204 includes a plurality of peaks 206 and a plurality of valleys 208. Along the axial direction of the sleeve 20, the distance between the peaks 206 and the openings 202 is smaller than the distance between the valleys 208 and the openings 202, thereby making the first slide rail 204 have a height difference in the axial direction of the sleeve 20. That is, when the connector 4 slides in the first slide rail 204 along the circumference of the sleeve 20, the height of the connector 4 in the axial direction of the sleeve 20 changes, thereby causing the lens 3 to tilt.

[0059] It is understandable that when the two connectors 4 are located in different positions and at different distances from the opening 202, the lens 3 can produce different tilt angles.

[0060] Furthermore, the second slide rail 30 is annular, and the second slide rail 30 includes a first wall surface near the opening 202 and a second wall surface away from the opening 202. The first wall surface and the second wall surface are arranged opposite to each other. Along the circumference of the sleeve 20, the distance between the first wall surface and the opening 202 remains unchanged, and the distance between the second wall surface and the opening 202 remains unchanged.

[0061] like Figure 3 As shown, according to some embodiments of this application, a plurality of peaks 206 and a plurality of valleys 208 are arranged intersectingly along the circumference of the sleeve 20.

[0062] In this embodiment, multiple peaks 206 and multiple valleys 208 are arranged in an intersecting manner, which facilitates the adjustment of the tilt angle of the lens 3 by the connector 4.

[0063] In practical applications, the first slide rail 204 extends in a wave-like shape.

[0064] According to some embodiments of this application, the connector 4 is rod-shaped or ball-shaped.

[0065] In this embodiment, such as Figure 4 , Figure 5 and Figure 6 As shown, when the connector 4 is rod-shaped, one end of the rod-shaped connector 4 extends into the first slide rail 204, and the other end extends into the second slide rail 30, allowing the connector 4 to move circumferentially along the sleeve 20 within the first slide rail 204 and the second slide rail 30. Simultaneously, the rod-shaped connector 4 ensures support for the lens 3, enhances the connection strength between the lens 3 and the sleeve 20, and prevents the lens 3 from detaching from the sleeve 20.

[0066] When the connector 4 is spherical, the spherical connector 4 can reduce the sliding resistance of the connector 4 in the first slide rail 204 and the second slide rail 30, thereby ensuring the drive of the lens 3 and improving the image stabilization effect of the shooting.

[0067] like Figure 1 and Figure 2 As shown, according to some embodiments of this application, the bracket assembly 2 further includes: a base 22, with the sleeve 20 connected to the base 22; a circuit board 24 disposed at the bottom of the base 22, with the lens 3 connected to the circuit board 24; a filter 26 disposed inside the base 22, with the lens 3 and the filter 26 correspondingly disposed; and a chip 28 disposed on the circuit board 24, with the chip 28 and the filter 26 correspondingly disposed.

[0068] In this embodiment, the support assembly 2 further includes a base 22, a circuit board 24, a filter 26, and a chip 28. The sleeve 20 is connected to the base 22, and the base 22 serves to support the sleeve 20. The circuit board 24 is disposed at the bottom of the base 22, the chip 28 is disposed on the circuit board 24, and the filter 26 is disposed at the bottom of the lens 3 and between the lens 3 and the chip 28. In this way, external light can pass through the lens 3 and enter the filter 26, and then be fed back to the chip 28 to realize the imaging of the camera module 1.

[0069] According to some embodiments of this application, the camera module 1 further includes: a first limiting member disposed on the first slide rail 204, and a portion of the connector 4 is disposed on the first slide rail 204 through the first limiting member; and a second limiting member disposed on the second slide rail 30, and a portion of the connector 4 is disposed on the second slide rail 30 through the second limiting member.

[0070] In this embodiment, the camera module 1 further includes a first limiting member and a second limiting member. The first limiting member is disposed on the first slide rail 204, and the connector 4 is connected to the first slide rail 204 through the first limiting member. The second limiting member is disposed on the second slide rail 30, and the connector 4 is connected to the second slide rail 30 through the second limiting member, thereby improving the connection strength between the lens 3 and the sleeve 20 and preventing the lens 3 from falling off the sleeve 20.

[0071] Understandably, the first limiting member is used to prevent the connector 4 from falling off the first slide rail 204, and the second limiting member is used to prevent the connector 4 from falling off the second slide rail 30.

[0072] like Figure 5 and Figure 6 As shown, the two support rods can slide independently and freely in the slide rail, thereby causing the lens 3 to form different tilt angles.

[0073] Specifically, when the user's camera shakes during shooting, the control device 6 analyzes the image and generates a motion signal to counteract the shaking. This motion signal is transmitted through the wiring in the sleeve 20 to the piezoelectric ceramic element 70 in the first slide rail 204, forming a drive signal. The two supports on the lens 3 are driven by the piezoelectric ceramic element 70, with one end sliding in the second slide rail 30 and the other end moving along the specially designed curved first slide rail 204 in the sleeve 20 to reach the target position specified by the drive signal. Because the two supports are in different positions, a height difference is created based on the shape of the curved first slide rail 204, causing the lens 3 to tilt at different angles, thus achieving image stabilization. The camera module 1 proposed in this application can achieve a larger anti-shake tilt angle, which is beneficial for improving the image stabilization effect.

[0074] According to some embodiments of this application, an electronic device is also proposed, including a camera module 1 as proposed in any of the above embodiments.

[0075] In this embodiment, the electronic device includes the camera module 1 proposed in any of the above embodiments, and therefore has all the beneficial effects of the camera module 1.

[0076] It should be noted that electronic devices can be smartphones, tablets, e-readers, wearable devices, etc., which will not be listed here.
