Lens carrying device, camera module and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 30, 2022, with application number 202211058238.0 and application name “Lens carrying device, camera module and electronic device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of terminal technology, and in particular to a lens carrying device, a camera module, and an electronic device. Background Art

[0003] With the explosive growth of electronic devices such as smartphones and tablets, electronic devices have more and more functions. Since people expect electronic devices to meet more functional requirements, the functions that electronic devices themselves can realize are increasing. For example, people expect electronic devices to have higher and higher camera performance to obtain high-resolution images. A camera module is set in the electronic device. The camera module includes a lens, a lens barrel and a photoelectric sensor. External light can reach the photoelectric sensor through the lens in the lens barrel. The photoelectric sensor converts the light signal into an electrical signal for forming an image. In the prior art, the lens and the lens barrel are both fixed, so when the overall position of the electronic device is fixed, the shooting angle range of the camera module is also fixed. When the electronic device as a whole moves, the camera module will also move synchronously, and the camera module has poor scene adaptability.

[0077] The electronic device in the embodiments of the present application can be referred to as user equipment (UE) or terminal, etc. For example, the electronic device can be a tablet computer (portable Android device, PAD), a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving (self-driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and other mobile terminals or fixed terminals. In the embodiments of the present application, the form of the terminal device is not specifically limited.

[0078] In an embodiment of the present application, FIG1 schematically shows the structure of an electronic device 10 according to an embodiment. Referring to FIG1 , the electronic device 10 is described as a handheld device with wireless communication function. The handheld device with wireless communication function may be, for example, a mobile phone.

[0079] Figure 2 schematically illustrates a partial structure of the back side of electronic device 10. Referring to Figures 1 and 2 , electronic device 10 according to an embodiment of the present application may include a display assembly 20 and a housing assembly 30. Display assembly 20 is coupled to housing assembly 30. The exposed display area of ​​display assembly 20 may be used to present image information to a user.

[0080] The electronic device 10 may include a mainboard and electronic components. The mainboard may be a printed circuit board (PCB). The electronic components are mounted on the mainboard. The electronic components are soldered to the mainboard using a soldering process. The electronic components may include, but are not limited to, a central processing unit (CPU), an intelligent algorithm chip, an image processing chip, or a power management IC (PMIC).

[0081] The electronic device 10 may include a camera module 40. The camera module 40 is used to capture a selected target and generate corresponding image information. The camera module 40 includes a light inlet. External light can enter the camera module 40 through the light inlet. The camera module 40 may be electrically connected to the mainboard, for example, via a flexible printed circuit (FPC).

[0082] For example, when the electronic device 10 is a mobile phone, the camera module 40 can be used as a rear camera or a front camera, which is not limited in this application.

[0083] The housing assembly 30 may include a battery cover. The battery cover has a through-hole. The through-hole is used to avoid the light inlet portion of the camera module 40. The through-hole extends through two opposing surfaces of the battery cover. For example, the cross-sectional shape of the through-hole may be circular, elliptical, or polygonal, but this application is not limited thereto.

[0084] The camera module 40 includes a lens, a focusing lens group and a photoelectric sensor. For example, the lens may include a prism 300. Figure 3 schematically shows the structure of the prism 300 of the present application. As shown in Figure 3, the prism 300 has a light incident surface 301, an inclined reflecting surface 302 and a light emitting surface 303. The light incident surface 301 and the light emitting surface 303 can be perpendicular to each other. The reflecting surface 302 can reflect the light incident on the light incident surface 301, and then emit it through the light emitting surface 303. The light emitted from the prism 300 can enter the focusing lens group and reach the photoelectric sensor after focusing adjustment by the focusing lens group. The photoelectric sensor can receive and perform photoelectric conversion, thereby forming an image.

[0085] In the related art, the prism 300 can be set in the lens barrel. The relative positions of the prism 300 and the lens barrel are fixed, so that the range of light received by the camera module is fixed, that is, the field of view of the camera module is fixed. In scenarios where it is necessary to follow the shot or take multiple pictures and stitch together a large field of view picture, it is necessary to move the electronic device 10 as a whole to adjust the shooting angle of the camera module for shooting. In addition, since the position of the prism 300 is relatively fixed, when the electronic device 10 as a whole shakes, the camera module will shake synchronously, resulting in blurred images taken by the camera module, affecting the imaging quality.

[0086] The lens supporting device 50 provided in the embodiment of the present application can realize the rotation of the lens, so that when the lens supporting device 50 is applied to the camera module 40, the camera module 40 can have a larger field of view or realize mobile tracking, and at the same time, the camera module 40 can also have anti-shake performance, which is beneficial to improving the scene adaptability and imaging quality of the camera module 40.

[0087] The following describes the implementation of the lens carrying device 50 provided in the embodiment of the present application.

[0088] Figure 4 schematically illustrates the overall structure of a lens support device 50 according to one embodiment. Figure 5 schematically illustrates a partially exploded view of the lens support device 50 according to one embodiment. Figure 6 schematically illustrates a partially exploded view of the lens support device 50 according to one embodiment. Referring to Figures 4 to 6 , the lens support device 50 according to one embodiment of the present application includes a base 60, a rotating support 70, a first actuator, a swing support 90, a second actuator, a lens support 110, and a third actuator.

[0089] The base 60 of the present application includes a first receiving portion 60a. The base 60 is used to provide a mounting base for other structural components. The lens supporting device 50 can be connected to other external structural components through the base 60 to fix the position of the lens supporting device 50 in the electronic device 10.

[0090] The rotating support 70 of the present application can be disposed within the first receiving portion 60a of the base 60. Part or all of the rotating support 70 can be located within the first receiving portion 60a. The rotating support 70 is rotatably connected to the base 60. When a force is applied to the rotating support 70, the rotating support 70 can rotate relative to the base 60 about the first axis P1. That is, the rotating support 70 can rotate in the plane of the X and Z directions shown in Figure 5. The rotating support 70 includes a second receiving portion 70a.

[0091] The first driver of the present application can be disposed between the base 60 and the rotating support 70. The first driver is configured to drive the rotating support 70 to rotate relative to the base 60 about the first axis P1. When the first driver is in operation, it can apply a rotational torque to the rotating support 70, causing the rotating support 70 to rotate relative to the base 60. When the first driver is in a stopped state, the first driver no longer applies a rotational torque to the rotating support 70. Therefore, the first driver can control the rotation direction and angle of the rotating support 70.

[0092] The swing support 90 of the present application can be disposed within the second accommodating portion 70a of the rotating support 70. Part or all of the swing support 90 can be located within the second accommodating portion 70a. The swing support 90 is rotatably connected to the rotating support 70. When a force is applied to the swing support 90, the swing support 90 can rotate relative to the rotating support 70 about the second axis P2. That is, the swing support 90 can rotate in the plane of the Y and Z directions shown in Figure 5. The first axis P1 and the second axis P2 can be perpendicular to each other. The swing support 90 includes a third accommodating portion 90a.

[0093] The second actuator of the present invention can be disposed between the rotating support 70 and the swing support 90. The second actuator is used to drive the swing support 90 to rotate about the second axis P2. When the second actuator is in operation, it applies a rotational torque to the swing support 90, causing it to swing relative to the rotating support 70. When the second actuator is in a stopped state, it no longer applies a rotational torque to the swing support 90. Therefore, the second actuator can control the rotational direction and angle of the swing support 90.

[0094] The lens holder 110 of the present application can be disposed within the third accommodating portion 90a of the swing support 90. Part or all of the lens holder 110 can be located within the third accommodating portion 90a. The lens holder 110 is rotatably connected to the swing support 90. When a force is applied to the lens holder 110, the lens holder 110 can rotate relative to the swing support 90 about the first axis P1, i.e., the lens holder 110 can rotate in the plane of the X and Z directions shown in Figure 5. Alternatively, when a force is applied to the lens holder 110, the lens holder 110 can rotate relative to the swing support 90 about the third axis P3, i.e., the lens holder 110 can rotate in the plane of the X and Y directions shown in Figure 5. Any two of the first axis P1, the second axis P2, and the third axis P3 are perpendicular to each other.

[0095] The third driver of the present application is disposed between the swing support 90 and the lens support 110 , and is used to drive the lens support 110 to rotate relative to the swing support 90 around the first axis P1 or around the third axis P3 .

[0096] The lens holder 110 can be used to support a lens. In some examples, the lens holder 110 can include a lens receiving portion 110a. The lens is disposed within the lens receiving portion 110a. The lens can be a prism 300. The lens holder 110 has an inclined positioning surface for cooperating with the reflective surface 302 of the prism 300. For example, as shown in FIG3 , the first axis P1 can be coplanar with the reflective surface 302 of the prism 300 and parallel to the light incident surface 301 and the light exit surface 303 of the prism 300. The second axis P2 can be perpendicular to the light exit surface 303 of the prism 300 and parallel to the light incident surface 301 of the prism 300. The third axis P3 can be perpendicular to the light incident surface 301 of the prism 300 and parallel to the light exit surface 303 of the prism 300.

[0097] In some possible implementations, the first, second, and third drivers can operate independently. For example, while the first driver drives the rotating support 70 to rotate, the second and third drivers can be stopped. This allows the rotating support 70 to drive the swing support 90 and the lens support 110 to rotate synchronously about the first axis P1, thereby enabling the lens to rotate about the first axis P1 and adjust its angle.

[0098] Alternatively, when the second driver drives the swing support 90 to rotate, the first driver and the third driver can be in a stopped state, so that the swing support 90 can drive the lens support 110 to rotate synchronously around the second axis P2 to achieve rotation of the lens around the second axis P2 and angle adjustment.

[0099] Alternatively, when the third driver drives the lens holder 110 to rotate, the first driver and the third driver may be in a stopped state, so that the lens holder 110 can rotate around the first axis P1 or the third axis P3 to achieve lens angle adjustment.

[0100] It is understood that any two of the first, second, and third drivers can be in operation simultaneously while the other is stopped. For example, when the first driver drives the rotating support 70 to rotate and the second driver drives the swing support 90 to rotate, the rotating support 70 can drive the swing support 90 and the lens support 110 to rotate synchronously about the first axis P1, while the swing support 90 can drive the lens support 110 to rotate synchronously about the second axis P2.

[0101] Alternatively, when the first driver drives the rotating support 70 to rotate and the third driver drives the lens support 110 to rotate, the rotating support 70 can drive the swing support 90 and the lens support 110 to rotate synchronously around the first axis P1, and the lens support 110 can rotate around the first axis P1 or the third axis P3.

[0102] Alternatively, when the second driver drives the swing support 90 to rotate and the third driver drives the lens support 110 to rotate, the swing support 90 can drive the lens support 110 to rotate synchronously around the second axis P2, and the lens support 110 can rotate around the first axis P1 or the third axis P3.

[0103] The first drive, the second drive and the third drive can also be in working state at the same time, so that the rotating support 70 can drive the swing support 90 and the lens support 110 to rotate synchronously around the first axis P1, and the swing support 90 can drive the lens support 110 to rotate synchronously around the second axis P2, and the lens support 110 can rotate around the first axis P1 or the third axis P3.

[0104] In some possible implementations, the first driver, the second driver, and the third driver may all be in communication with a central processing unit, and the central processing unit may be configured to control the first driver, the second driver, and the third driver to switch between a working state and a stopped state.

[0105] The lens supporting device 50 of the embodiment of the present application can control the rotation of the rotating support 70, the swing support 90, and the lens support 110 through the first driver, the second driver, and the third driver, respectively, to achieve the angle adjustment of the lens. The rotating support 70 drives the swing support 90 and the lens support 110 to rotate around the first axis P1. The swing support 90 can drive the lens support 110 to rotate around the second axis P2. When the position of the lens support 110 changes, the position of the lens light-entry area set on the lens support 110 can be changed, so that the camera module 40 with the lens supporting device 50 can obtain a larger field of view. When the electronic device 10 as a whole does not move, the camera module 40 can adjust the angle of the lens to achieve continuous shooting at different angles to splice a large field of view image or realize video tracking, so that the camera module 40 can adapt to more scenarios. When the lens holder 110 rotates around the first axis P1 or the third axis P3 , the lens holder 110 can ensure that the position of the lens mounted on the lens holder 110 is stable, thereby achieving anti-shake, which is beneficial to improving the imaging quality of the camera module 40 .

[0106] In some achievable embodiments, as shown in Figures 4 and 5, the lens supporting device 50 further includes a housing 130. The housing 130 may be connected to the base 60, for example, the housing 130 may be detachably connected to the base 60. The base 60, the rotating support 70, the swing support 90, the lens support 110, and the lens are located within the housing 130. The housing 130 may provide protection for internal structural components. The housing 130 includes a light-transmitting hole 131. The lens receiving portion 110a of the lens support 110 may correspond to the light-transmitting hole 131, so that when a lens is arranged in the lens receiving portion 110a, the lens may correspond to the light-transmitting hole 131. In some examples, the housing 130 may be a pentahedral structure. The light-transmitting hole 131 passes through two adjacent side walls of the housing 130, that is, a portion of the light-transmitting hole 131 is arranged on one side wall, and the other portion is arranged on the other side wall. When the lens is a prism 300, the light incident surface 301 and light emitting surface 303 of the prism 300 correspond to two adjacent side walls of the housing 130 where the light-transmitting hole 131 is provided. External light can pass through the light-transmitting hole 131 and reach the prism 300. Then, after being reflected by the prism 300, the light emitted from the light-emitting surface 303 can be emitted through the light-transmitting hole 131.

[0107] In some embodiments, the first driver includes a first sensing member 80 and a first driving member 81. The first sensing member 80 is provided on one of the base 60 and the rotating support 70, and the first driving member 81 is provided on the other. The first driving member 81 and the first sensing member 80 can interact with each other to generate a rotational torque in the rotating support 70, thereby driving the rotating support 70 to rotate about the first axis P1.

[0108] In some examples, Figure 7 schematically illustrates a partial structure of the lens carrier 50 of the present application. Figure 8 schematically illustrates a partial structure of the lens carrier 50 of the present application. As shown in Figures 7 and 8, a first driving member 81 is disposed on the base 60, and a first sensing member 80 is disposed on the rotating support 70. The base 60 may include a first side plate 61 and a first bottom plate 62 connected to each other. The first side plate 61 and the first bottom plate 62 intersect with each other. Along the second axis P2, the first side plate 61 of the base 60 is located on one side of the rotating support 70. The first driving member 81 can be disposed on the first side plate 61 of the base 60. The first sensing member 80 can be disposed on the rotating support 70. The first driving member 81 can interact with the first sensing member 80 to generate a driving force. The relative positions of the first sensing member 80 and the first driving member 81 change, causing the first sensing member 80 to drive the rotating support 70 to rotate synchronously. Along the third axis P3, the rotating support 70 is located on the side of the first bottom plate 62 facing the first receiving portion 60a. Along the first axis P1, the first side plate 61 of the base 60 is located on the outside of the rotating support 70, and along the third axis P3, the first bottom plate 62 of the base 60 is located on the outside of the rotating support 70, so that the first side plate 61 and the first bottom plate 62 can respectively form protection for the rotating support 70 on the outside of the rotating support 70.

[0109] For example, the housing 130 may be connected to the first bottom plate 62. For example, the housing 130 may be bonded, welded, or connected to the first bottom plate 62 using fasteners. The first side plate 61 may be located within the housing 130.

[0110] In some examples, the base 60 further includes a second side plate 63. The first side plate 61 and the first bottom plate 62 are connected to the second side plate 63, thereby enclosing a first accommodating portion 60a. Two second side plates 63 are spaced apart from the first side plate 61 along the first axis P1. A swivel support 70 is disposed between the two second side plates 63. The swivel support 70 is rotatably connected to the second side plates 63 of the base 60.

[0111] Exemplarily, the rotating support 70 may include a third side plate 71 and a fourth side plate 72. Along the first axis P1, the two third side plates 71 are spaced apart from the fourth side plate 72. The third side plate 71 and the fourth side plate 72 may be enclosed to form a second accommodating portion 70a. The third side plate 71 of the rotating support 70 is rotatably connected to the base 60, for example, it may be rotatably connected to the second side plate 63 of the base 60. Along the second axis P2, the first side plate 61 of the base 60 is arranged facing the fourth side plate 72 of the rotating support 70. The first driver may be arranged between the first side plate 61 of the base 60 and the fourth side plate 72 of the rotating support 70. For example, a first driving member 81 may be provided on the first side plate 61 of the base 60, and a first sensing member 80 may be provided on the fourth side plate 72 of the rotating support 70.

[0112] When the first driving member 81 is in the working state, the first driving member 81 and the first sensing member 80 can sense each other, so that the first driving member 81 can generate an induction force with the first sensing member 80. This induction force can serve as the driving force for driving the rotating support 70 to rotate. Along the second axis P2, the first driving member 81 and the first sensing member 80 are spaced apart, that is, the first driving member 81 and the first sensing member 80 do not contact each other. Therefore, there is no need for a transmission structure to transmit the force between the first driving member 81 and the first sensing member 80, so there is no friction resistance between the first driving member 81 and the first sensing member 80, which is beneficial to improving the rotation accuracy of the rotating support 70. At the same time, it is also beneficial to reduce the possibility of rotational impact force of the rotating support 70 at the start or stop of rotation due to the existence of frictional resistance, thereby ensuring that the position movement process of the lens support 110 is stable and the position movement accuracy is high.

[0113] In some examples, an induction force can be generated between the first driving member 81 and the first induction member 80 by magnetic induction. Exemplarily, the first induction member 80 can be a magnet. For example, the first induction member 80 can be a permanent magnet. The first induction member 80 includes but is not limited to a neodymium iron boron magnet or an alnico magnet. The first driving member 81 can be a coil. For example, the material of the first driving member 81 can be copper or a copper alloy. When the first driving member 81 is powered on, it is in a working state to generate a magnetic force. When the first driving member 81 is powered off, it is in a stopped state and does not generate a magnetic force. By controlling the current in the first driving member 81, the magnetic force generated by the first driving member 81 can be controlled. The first induction member 80 can sense the change in the current in the first driving member 81, thereby generating a driving force to drive the rotating support 70 to drive the rotating support 70 to rotate.

[0114] In some feasible embodiments, as shown in Figure 8, the outer surface of the first side plate 61 of the first sensing member 80 facing the base 60 can be raised toward the first side plate 61 and be arc-shaped, that is, the outer surface of the first sensing member 80 facing away from the second accommodating portion 70a is raised and be arc-shaped, so that when the rotating support 70 and the first sensing member 80 rotate together around the first axis P1, a small gap can be maintained between the first sensing member 80 and the first driving member 81, thereby ensuring that the driving force generated by the first driving member 81 and the first sensing member 80 is stable, which is beneficial to improving the rotation stability of the rotating support 70 and the accuracy of the rotation angle.

[0115] In some examples, the outer surface of the fourth side plate 72 of the rotating support 70 facing the first side plate 61 is raised and has an arc shape, that is, the outer surface of the fourth side plate 72 facing away from the second accommodating portion 70a is raised and has an arc shape. The outer surface of the fourth side plate 72 can have the same shape as the outer surface of the first sensing member 80. The outer surface of the fourth side plate 72 can be flush with the outer surface of the first sensing member 80. A portion of the first sensing member 80 is embedded in the fourth side plate 72. Exemplarily, the outer surface of the first sensing member 80 facing the first side plate 61 and the outer surface of the fourth side plate 72 facing the first side plate 61 are both arc-shaped.

[0116] In some examples, the inner surface of the first sensing member 80 may be recessed toward the first side plate 61 and have an arc shape. Both the outer and inner surfaces of the first sensing member 80 are arc-shaped, for example, circular arc-shaped. The outer and inner surfaces of the first sensing member 80 have the same shape, such that the central axis of the outer surface coincides with the central axis of the inner surface, thereby forming a uniform thickness structure for the first sensing member 80. For example, the central axis of the outer surface and the central axis of the inner surface may both coincide with the first axis P1.

[0117] Alternatively, the inner surface of the first induction member 80 may be a plane. For example, the inner surface of the first induction member 80 may be parallel to the first axis P1.

[0118] In some examples, the rotating support 70 includes a first insulating portion 701 and a first magnetically conductive metal sheet 702. The first insulating portion 701 is disposed on the outer surface of the first magnetically conductive metal sheet 702. The first magnetically conductive metal sheet 702 and the first sensing member 80 can be attracted to each other by magnetic attraction, thereby securing the first sensing member 80 to the rotating support 70. This eliminates the need for an additional connecting structure between the first sensing member 80 and the rotating support 70, resulting in a simple connection structure. A receiving recess can be provided on the surface of the first insulating portion 701 facing the base 60. The shape of the receiving recess is the same as that of the first sensing member 80. The first sensing member 80 can be disposed within the receiving recess, further ensuring the accurate installation position of the first sensing member 80 and improving the reliability and stability of the connection between the first sensing member 80 and the fourth side plate 72. The outer surface of the first insulating portion 701 can be the same shape as that of the first sensing member 80. The outer surface of the first insulating portion 701 can be flush with the outer surface of the first sensing member 80, so that the first insulating portion 701 does not obstruct the outer surface of the first sensing member 80 facing the base 60.

[0119] For example, the inner surface of the first sensing member 80 can be directly bonded to the first magnetic conductive metal sheet 702. For example, the inner surface of the first sensing member 80 may be curved, and the inner surface area of ​​the first magnetic conductive metal sheet 702 corresponding to the first sensing member 80 may be raised, so that the inner surface of the first sensing member 80 can be directly bonded to the first magnetic conductive metal sheet 702. Alternatively, the inner surface of the first sensing member 80 may be flat, and the inner surface area of ​​the first magnetic conductive metal sheet 702 corresponding to the first sensing member 80 may be flat.

[0120] For example, the inner surface area of ​​the first magnetic conductive metal sheet 702 corresponding to the first inductive element 80 can be flat. A portion of the first insulating portion 701 is located between the first magnetic conductive metal sheet 702 and the inner surface of the first inductive element 80, so that the inner surface of the first inductive element 80 and the first insulating portion 701 can directly contact each other.

[0121] For example, both ends of the first magnetic conductive metal sheet 702 are located on the third side plate 71. The middle portion of the first magnetic conductive metal sheet 702 is located on the fourth side plate 72. The middle portion of the first magnetic conductive metal sheet 702 and the first induction element 80 can be attracted to each other by magnetic attraction.

[0122] For example, the material of the first insulating portion 701 may include, but is not limited to, plastic. The material of the first magnetic conductive metal sheet 702 may include, but is not limited to, steel.

[0123] In some examples, as shown in Figures 6 and 7, the first side plate 61 of the base 60 includes a first insulating frame 611 and a first magnetic conductive metal plate 612. The first magnetic conductive metal plate 612 is disposed on the first insulating frame 611 and covers the central hole of the first insulating frame 611. The first driving member 81 can be disposed on the surface of the first magnetic conductive metal plate 612 facing the first accommodating portion 60a. For example, the material of the first insulating frame 611 can be plastic. The material of the first magnetic conductive metal plate 612 can be steel.

[0124] In some examples, the number of the first sensing members 80 and the first driving members 81 can both be two. Along the first axis P1, the two first sensing members 80 are spaced apart on the rotating support 70. The position of the first driving member 81 is set in a one-to-one correspondence with the position of the first sensing member 80. The two first driving members 81 can generate driving force simultaneously with the two first sensing members 80, respectively, so that the overall force of the rotating support 70 is more balanced, which is beneficial to improving the rotation stability of the rotating support 70. It can be understood that the number of the first sensing members 80 and the first driving members 81 is not limited to the above number, but can be set to other numbers as required. For example, the number of the first sensing members 80 and the first driving members 81 can both be more than three, and this application does not limit this.

[0125] In some embodiments, as shown in FIG. 7 , the lens carrier 50 further includes a first angle sensor 140. The first angle sensor 140 is disposed on the base 60. When the first driving member 81 and the first sensing member 80 jointly drive the rotating support 70 to rotate, the first angle sensor 140 can be used to detect the angle of rotation of the rotating support 70 about the first axis P1, thereby facilitating control of the rotation angle of the rotating support 70 and improving the accuracy of the rotation angle of the rotating support 70.

[0126] In some examples, the first angle sensor 140 can be in communication with the central processing unit. The first angle sensor 140 can detect the rotation angle of the rotating support 70 in real time and control the driving force generated by the first driving member 81 and the first sensing member 80 to control the rotation angle of the rotating support 70.

[0127] In some examples, the first sensing member 80 may be a magnet, the first angle sensor 140 may be a Hall sensor, the first driving member 81 may be a coil, and the first angle sensor 140 may be located in a central hole of the first driving member 81 .

[0128] In some achievable embodiments, FIG9 schematically shows a partial cross-sectional structure of the lens supporting device 50 of the present application. FIG10 is an enlarged view of point M in FIG9. FIG11 schematically shows a partial structure of the lens supporting device 50 of the present application. Referring to FIG9 to FIG11 , the lens supporting device 50 further includes a brake assembly 150. The brake assembly 150 is disposed in the first accommodating portion 60a. The brake assembly 150 is disposed between the base 60 and the rotating support 70. The brake assembly 150 is used to brake the rotating support 70. When the rotating support 70 rotates to a predetermined angle, the brake assembly 150 brakes the rotating support 70 so that the rotating support 70 remains stably in the current position, is less likely to shake, and reduces the possibility of the rotating support 70 shifting from the predetermined position, thereby improving the position stability of the rotating support 70 and thereby ensuring that the position of the lens remains stable. After the brake assembly 150 brakes the rotatable support 70, the first driving member 81 can be in a stopped state, and no driving force is generated between the first driving member 81 and the first sensing member 80. When the rotatable support 70 needs to rotate to adjust its position, the brake assembly 150 releases the rotatable support 70, and the first driving member 81 and the first sensing member 80 generate a driving force to drive the rotatable support 70 to rotate.

[0129] In some examples, as shown in FIG. 10 , the brake assembly 150 includes a stopper 151 and a stopper 152. The stopper 151 is provided on one of the rotating support 70 and the base 60, and the stopper 152 is provided on the other. The stopper 151 and the stopper 152 engage or disengage to brake or release the rotating support 70. When the rotating support 70 rotates to a predetermined angle, the stopper 151 and the stopper 152 engage to brake the rotating support 70. When the stopper 151 and the stopper 152 are engaged, relative movement between the stopper 151 and the stopper 152 is unlikely to occur, which helps further improve the positional stability of the rotating support 70.

[0130] Exemplarily, a limiting portion 151 is provided on the rotating support 70 , and a limiter 152 is provided on the base 60 .

[0131] For example, there may be two first sensing members 80. Along the first axis P1, the limiter 151 is disposed between the two first sensing members 80. There may be two first driving members 81. Along the first axis P1, the limiter 152 is disposed between the two first driving members 81.

[0132] Exemplarily, the rotating support 70 includes a third side plate 71 and a fourth side plate 72. The fourth side plate 72 is provided with a limiter 151. The base 60 includes a first side plate 61. The first side plate 61 is provided with a limiter 152.

[0133] In some examples, as shown in FIG11 , the limiter 152 includes a limit spring 1521 and an actuator 1522 . The actuator 1522 is used to drive the limit spring 1521 to engage with or disengage from the limit portion 151 , thereby braking or releasing the rotating support 70 .

[0134] In some examples, as shown in FIG10 , the limiting portion 151 includes a limiting groove. Multiple limiting grooves are arranged side by side along a direction perpendicular to the first axis P1 and the second axis P2 (e.g., the Z direction shown in FIG10 ), that is, multiple limiting grooves can be arranged side by side along the third axis P3. The actuator 1522 is used to drive the limiting spring 1521 to engage or disengage with the limiting groove. For example, the limiting spring 1521 can engage or disengage with any of the limiting grooves.

[0135] Taking the initial state in which the limiting spring piece 1521 is engaged with the limiting groove as an example, when the swivel support 70 needs to be rotated and adjusted, the actuator 1522 can apply a force to the limiting spring piece 1521, causing the limiting spring piece 1521 to move away from the limiting groove and exit from the limiting groove to separate and release the swivel support 70. When the swivel support 70 is rotated to a predetermined angle, the actuator 1522 can release the limiting spring piece 1521, which can then reset and insert the limiting spring piece 1521 into the limiting groove, achieving engagement and braking the swivel support 70. After the limiting spring piece 1521 is engaged with the limiting groove, relative movement between the limiting spring piece 1521 and the limiting groove is unlikely to occur, thereby limiting the swivel support 70 from rotating forward or reverse, and thus preventing the swivel support 70 from shifting.

[0136] There is a spacing between two adjacent limiting grooves. When one of the two adjacent limiting grooves engages the limiting spring 1521, the rotatable support 70 is in the first position; when the other one engages the limiting spring 1521, the rotatable support 70 is in the second position. Therefore, by adjusting the spacing between the two adjacent limiting grooves, the rotation angle of the rotatable support 70 from the first position to the second position can be controlled. Exemplarily, the plurality of limiting grooves are evenly distributed along the third axis P3. Exemplarily, along the third axis P3, the number of limiting grooves on both sides of the first axis P1 can be equal.

[0137] For example, Figure 12 is an enlarged view of point W in Figure 8 . Referring to Figures 8 and 12 , a limiting portion 151 is provided on the surface of the fourth side plate 72 facing the base 60. A limiting groove may be provided on the fourth side plate 72 of the rotating support 70, for example, in the center region of the fourth side plate 72.

[0138] For example, the outer surface of the fourth side plate 72 has a raised, curved area. A retaining groove may be provided in the middle of the raised, curved area along the first axis P1. Alternatively, retaining grooves may be provided at both ends of the raised, curved area along the first axis P1.

[0139] For example, referring to Figures 8 and 10, the rotating support 70 includes a first insulating portion 701 and a first magnetic metal sheet 702. The first insulating portion 701 is arranged on the outer surface of the first magnetic metal sheet 702. The first magnetic metal sheet 702 and the first induction member 80 can attract each other through magnetic attraction to fix the first induction member 80 on the rotating support 70. A limiting groove is provided on the first magnetic metal sheet 702. The first magnetic metal sheet 702 itself has a large mechanical strength, so when the limiting spring piece 1521 and the limiting groove are engaged, the first magnetic metal sheet 702 is not easily deformed under the action of the limiting spring piece 1521. In addition, when the limiting spring piece 1521 and the limiting groove are frequently engaged or separated, the first magnetic metal sheet 702 is less likely to have friction loss, which may cause the limiting groove to expand and increase in size. This reduces the possibility that the limiting groove will expand and increase in size, resulting in poor engagement between the limiting spring piece 1521 and the limiting groove or the occurrence of a gap between the two, which is beneficial to ensuring that the limiting spring piece 1521 and the limiting groove maintain good matching accuracy for a long time.

[0140] As shown in Figure 12, the first insulating part 701 can be provided with an avoidance groove 701a. A limiting groove is provided on the area of ​​the first magnetic conductive metal sheet 702 corresponding to the avoidance groove 701a. The avoidance groove 701a of the first insulating part 701 is used to avoid the part of the limiting spring piece 1521 that is used to engage with the limiting groove, so as to avoid positional interference between the limiting spring piece 1521 and the first insulating part 701, resulting in the limiting spring piece 1521 failing to accurately engage with the limiting groove or failing to fully engage with the limiting groove. The number and position of the avoidance grooves 701a of the first insulating part 701 can be set in a one-to-one correspondence with the number and position of the limiting grooves. For example, along the first axis P1, the limiting groove is located in the middle area of ​​the avoidance groove 701a.

[0141] 7 and 10 , the base 60 includes a first side plate 61 and a first bottom plate 62 connected to each other. The first side plate 61 is provided with an actuating member 1522 and a limiting spring 1521 .

[0142] For example, Figure 13 schematically illustrates a partial structure of the brake assembly 150 of the present application. As shown in Figure 13 , the retaining spring 1521 has a protrusion 1521d. The retaining spring 1521 can be engaged with or disengaged from the retaining groove via the protrusion 1521d. The protrusion 1521d can be a strip-shaped structure extending along the first axis P1.

[0143] For example, as shown in FIG13 , the limiting spring piece 1521 includes a first extension section 1521a, a second extension section 1521b, and a third extension section 1521c. The first extension section 1521a and the third extension section 1521c are respectively disposed on either side of the second extension section 1521b. The first extension section 1521a is connected to the base 60. The actuator 1522 is located between the third extension section 1521c and the base 60. The actuator 1522 is energized or deenergized to drive the third extension section 1521c to engage or disengage with the limiting groove. For example, the third extension section 1521c has a protrusion 1521d. The third extension section 1521c can be engaged or disengaged with the limiting groove via the protrusion 1521d.

[0144] Exemplarily, the first extension section 1521a is connected to the base 60. A gap is provided between the third extension section 1521c and the base 60.

[0145] For example, the angle between the first extension section 1521a and the second extension section 1521b can be an obtuse angle. The angle between the third extension section 1521c and the second extension section 1521b can also be an obtuse angle. The first extension section 1521a and the third extension section 1521c can be arranged parallel to each other. After the limiting spring piece 1521 is connected to the first side plate 61 via the first extension section 1521a, the second extension section 1521b is inclined to form a gap between the third extension section 1521c and the first side plate 61.

[0146] Exemplarily, the brake assembly 150 further includes a limiting member 153. The limiting member 153 is used to limit the limiting spring piece 1521 along the first axis P1. When the limiting spring piece 1521 is subjected to a force along the first axis P1 and swings, the limiting member 153 can block the limiting spring piece 1521 to effectively reduce the swing amplitude of the limiting spring piece 1521 along the first axis P1, and reduce the possibility that the limiting spring piece 1521 cannot accurately engage with the limiting groove due to deformation and separation of the limiting spring piece 1521 from the predetermined engaging position. Exemplarily, the limiting member 153 can be a plate-shaped structure. The limiting spring piece 1521 and the limiting member 153 are arranged on the first side plate 61 of the base 60. Exemplarily, the limiting spring piece 1521 can be provided with a limiting hole 1521e. The limiting member 153 is passed through the limiting hole 1521e. Specifically, a limiting hole 1521e may be provided on the second extension section 1521b of the limiting spring piece 1521. The limiting hole 1521e passes through the second extension section 1521b along the second axis P2.

[0147] Exemplarily, the limiting spring piece 1521 can be a magnetic conductive structure. For example, the material of the limiting spring piece 1521 can include, but is not limited to, steel. The actuator 1522 can be an electromagnet. The actuator 1522 can be arranged between the limiting spring piece 1521 and the base 60. For example, the actuator 1522 can be arranged between the third extension section 1521c and the base 60. The actuator 1522 is powered off or powered on to drive the limiting spring piece 1521 to engage or separate with the limiting groove. For example, the actuator 1522 can be located between the third extension section 1521c and the first side plate 61. When the actuator 1522 is powered on, a magnetic attraction force is generated, and the actuator 1522 adsorbs the third extension section 1521c, so that the third extension section 1521c moves close to the actuator 1522 and separates from the limiting groove. When the actuating member 1522 is powered off, the actuating member 1522 releases the third extending section 1521 c so that the third extending section 1521 c moves away from the actuating member 1522 and engages with the limiting groove.

[0148] The first side plate 61 of the base 60 includes a first insulating frame 611 and a first magnetically conductive metal plate 612. The first magnetically conductive metal plate 612 is disposed on the first insulating frame 611 and covers the center hole of the first insulating frame 611. The first driving member 81 can be disposed on the surface of the first magnetically conductive metal plate 612 facing the first accommodating portion 60a. For example, the material of the first insulating frame 611 can include, but is not limited to, plastic. The material of the first magnetically conductive metal plate 612 can include, but is not limited to, steel. The limiting spring 1521 can be disposed on the first magnetically conductive metal plate 612. For example, the first extension 1521a of the limiting spring 1521 can be connected to the first magnetically conductive metal plate 612. The first extension 1521a can be welded, adhesively bonded, or connected to the first magnetically conductive metal plate 612 using fasteners. The actuator 1522 can be disposed on the first magnetically conductive metal plate 612 and located between the third extension 1521c and the first magnetically conductive metal plate 612. When the actuator 1522 is powered on, it generates a magnetic attraction force, which attracts the third extension section 1521c, causing the third extension section 1521c to move closer to the actuator 1522 and separate from the retaining groove. When the actuator 1522 is powered off, the actuator 1522 releases the third extension section 1521c, causing the third extension section 1521c to move away from the actuator 1522 and engage with the retaining groove.

[0149] For example, FIG14 schematically shows a partial cross-sectional structure of the lens carrying device 50 of the present application. As shown in FIG14 , the actuator 1522 can be a shape memory alloy (SMA) component. The limiting spring 1521 is connected to the actuator 1522. When the actuator 1522 is powered on or off, telescopic changes can be achieved. The actuator 1522 is powered on or off to drive the limiting spring 1521 to engage or separate with the limiting groove. Therefore, the structure of the actuator 1522 for driving the limiting spring 1521 is simple, which is conducive to reducing the number of parts used, reducing the difficulty of assembly and saving installation space.

[0150] One end of the actuator 1522 can be connected to the third extension section 1521c of the limiting spring 1521, and the other end can be connected to the first extension section 1521a, the end of the second extension section 1521b near the first extension section 1521a, or the base 60. The actuator 1522 is located on the side of the limiting spring 1521 facing the base 60. For example, the actuator 1522 is located on the side of the limiting spring 1521 facing the first side plate 61. When the actuator 1522 is energized and retracted, the actuator 1522 can drive the third extension section 1521c to move closer to the base 60 and separate from the limiting groove. When the actuator 1522 is de-energized, the actuator 1522 returns to its original length and releases the third extension section 1521c, allowing the third extension section 1521c to move away from the base 60 and engage with the limiting groove.

[0151] In some achievable embodiments, the base 60 includes a first side plate 61, a second side plate 63, and a first bottom plate 62 that are connected. The first side plate 61, the second side plate 63, and the first bottom plate 62 enclose a first accommodating portion 60a. Along the first axis P1, two second side plates 63 are spaced apart from the first side plate 61. Along the second axis P2, the first side plate 61 is located on one side of the rotating support 70. Along the third axis P3, the rotating support 70 is located on the side of the first bottom plate 62 facing the first accommodating portion 60a. Along the first axis P1, the second side plates 63 are respectively provided on both sides of the rotating support 70. For example, the rotating support 70 is provided between the two second side plates 63. Figure 15 schematically shows a partial structure of the lens supporting device 50 of the present application. As shown in Figure 15, the rotating support 70 includes a rotating shaft 73. The rotating support 70 is rotatably connected to the second side plate 63 via the rotating shaft 73.

[0152] Exemplarily, the rotating support 70 includes two rotating shafts 73. Along the first axis P1, the two rotating shafts 73 are respectively located on both sides of the second receiving portion 70a. The two rotating shafts 73 are rotatably connected to the two second side plates 63 respectively.

[0153] For example, the axis of the rotating shaft 73 may coincide with the first axis P1 .

[0154] In some examples, the pivot support 70 includes a third side plate 71 and a fourth side plate 72 connected to each other. Along the first axis P1, the two third side plates 71 are spaced apart from the fourth side plate 72. The third side plate 71 is located on the side of the second side plate 63 facing the first receiving portion 60a. The third side plate 71 is rotatably connected to the second side plate 63 via a rotating shaft 73. Along the second axis P2, the first actuator is disposed between the first side plate 61 and the fourth side plate 72.

[0155] In some examples, the second side plate 63 of the base 60 includes an axial hole. The rotating shaft 73 of the rotating support 70 mates with the axial hole of the second side plate 63. At least a portion of the rotating shaft 73 of the rotating support 70 is disposed within the axial hole. A rolling element is disposed between the rotating shaft 73 of the rotating support 70 and the second side plate 63. The rolling element is disposed within the axial hole of the second side plate 63. The rolling element can effectively reduce the rotational resistance of the rotating support 70 when it rotates relative to the second side plate 63, thereby allowing the first driver to drive the rotating support 70 to rotate with a relatively small driving force. For example, the rolling element can be a spherical structure.

[0156] In some examples, at least one second side plate 63 includes an axial stop 631 (see FIG. 7 ). Along the first axis P1, the rotation shaft 73 of the rotation support 70 can be disposed on the side of the axial stop 631 facing the first accommodating portion 60a. The axial stop 631 can block the rotation support 70 along the first axis P1, preventing the rotation shaft 73 of the rotation support 70 from shifting along the first axis P1 due to a force acting along the first axis P1. This, on the one hand, reduces the possibility of the rotation support 70 shifting along the first axis P1 and causing the lens to shift. On the other hand, it reduces the possibility of the rotation support 70 shifting along the first axis P1 and causing the limiter 151 and the stopper 152 to become stuck. Furthermore, it reduces the possibility of the rotation shaft 73 of the rotation support 70 dislodging from the shaft hole, which could cause the lens carrier 50 to malfunction.

[0157] For example, a guide groove is provided on the rotating shaft 73. The inner wall of the shaft hole of one second side plate 63 is provided with a guide groove. The rolling body is provided between the guide groove of the rotating shaft 73 and the guide groove of the second side plate 63, so that the second side plate 63, the rolling body and the rotating shaft 73 can form a limit with each other. The other second side plate 63 includes an axial stop portion 631. The inner wall of the shaft hole of the second side plate 63 on which the axial stop portion 631 is provided is a smooth inner wall. The rolling body is located between the guide groove of the rotating shaft 73 and the smooth inner wall of the shaft hole. The axial stop portion 631 is located on the side of the shaft hole away from the first accommodating portion 60a. After the rotating shaft 73 is assembled with the second side plate 63, the end face of the rotating shaft 73 can be pressed against the surface of the axial stop portion 631 facing the shaft hole.

[0158] In some examples, as shown in Figure 15 , the rotating shaft 73 of the rotating support 70 can be semicircular. The rotating shaft 73 includes a connected arcuate surface 731 and a flat surface 732. The shaft hole of the second side plate 63 is semicircular. A rolling element is disposed between the arcuate surface 731 of the rotating shaft 73 and the inner wall of the shaft hole. Figure 16 schematically illustrates the structure of the baffle of the present application. As shown in Figures 15 and 16 , the base 60 also includes a baffle 64. The baffle 64 can be connected to the second side plate 63. The rotating shaft 73 is located between the baffle 64 and the second side plate 63. The baffle 64 includes a clearance notch 641. The clearance notch 641 of the baffle 64 is connected to the shaft hole of the second side plate 63. Along the second axis P2, the flat surface 732 of the rotating shaft 73 faces the clearance notch 641 of the baffle 64. The clearance notch 641 of the baffle 64 is used to clear the rotating shaft 73, thereby providing space for the rotating shaft 73 to rotate. When the shaft 73 rotates and the lower end or upper end of the shaft 73 enters the avoidance gap 641 and presses against the baffle 64, the shaft 73 is constrained by the baffle 64 and no longer rotates, so that the maximum rotation angle of the shaft 73 can be limited by the baffle 64, so that the rotation range of the shaft 73 can be controlled, reducing the possibility of the rotating support 70, the swing support 90 or the lens support 110 colliding with the base 60 due to the excessive rotation angle of the shaft 73 of the rotating support 70.

[0159] Exemplarily, the distance between the flat surface 732 of the rotating shaft 73 and the bottom wall of the avoidance notch 641 facing the flat surface 732 is smaller than the diameter of the rolling body, so that the maximum distance between the arc surface 731 of the rotating shaft 73 and the hole wall of the shaft hole is smaller than the diameter of the rolling body, so that the rolling body will not fall out from between the rotating shaft 73 and the second side plate 63.

[0160] In some examples, the second side plate 63 includes a first mounting slot 632 and a second mounting slot 633 that are interconnected. The shaft hole is connected to the first mounting slot 632. The rotating shaft 73 of the rotating support 70 can be installed in the shaft hole of the second side plate 63 through the first mounting slot 632. Along the third axis P3, the first mounting slot 632 includes two opposing side walls. The second mounting slot 633 is provided on the side wall of the first mounting slot 632. The baffle 64 includes a stopper 642 and a fixing portion 643. The shapes of the stopper 642 and the fixing portion 643 match the shapes of the first mounting slot 632 and the second mounting slot 633, respectively. The stopper 642 of the baffle 64 can be provided in the first mounting slot 632, while the fixing portion 643 of the baffle 64 can be provided in the second mounting slot 633, thereby connecting and fixing the baffle 64 to the second side plate 63. The avoidance notch 641 is provided in the stopper 642.

[0161] For example, along the first axis P1, the second mounting groove 633 may not extend through the two opposing surfaces of the second side plate 63. The opening of the second mounting groove 633 may be located on the surface of the second side plate 63 facing away from the first accommodating portion 60a. Along the first axis P1, the stopper 642 and the fixing portion 643 of the baffle 64 are aligned with the first mounting groove 632 and the second mounting groove 633, respectively. Then, a force is applied to press the stopper 642 and the fixing portion 643 into the first mounting groove 632 and the second mounting groove 633. The surfaces of the stopper 642 and the fixing portion 643 facing away from the first accommodating portion 60a may be flush with the surface of the second side plate 63.

[0162] In some embodiments, Figures 17 and 18 schematically illustrate a partial structure of the lens support device 50 of the present application. As shown in Figures 17 and 18 , the second driver includes a second sensing member 100 and a second driving member 101. The second sensing member 100 is provided on one of the rotating support 70 and the swing support 90, while the second driving member 101 is provided on the other. The second driving member 101 interacts with the second sensing member 100, causing the swing support 90 to generate a rotational torque, thereby driving the swing support 90 to rotate about the second axis P2.

[0163] When the second driving member 101 is in operation, the second driving member 101 and the second sensing member 100 can sense each other, thereby generating an inductive force between the second driving member 101 and the second sensing member 100. This inductive force can serve as a driving force to drive the swing support 90 to rotate. The second driving member 101 and the second sensing member 100 are spaced apart, that is, the second driving member 101 and the second sensing member 100 do not contact each other. Therefore, no transmission structure is required to transmit the force between the second driving member 101 and the second sensing member 100, so there is no friction resistance between the second driving member 101 and the second sensing member 100, which is beneficial to improving the rotation accuracy of the swing support 90. It is also beneficial to reducing the possibility of rotational impact force on the swing support 90 at the start or stop of rotation due to friction resistance, thereby ensuring that the position movement process of the lens support 110 is stable and the position movement accuracy is high.

[0164] In some examples, the rotating support 70 includes a third side plate 71 and a fourth side plate 72 connected to each other. Along the first axis P1, the two third side plates 71 are spaced apart from the fourth side plate 72. The third side plate 71 is rotatably connected to the base 60. The swing support 90 is disposed between the two third side plates 71. The swing support 90 is rotatably connected to the fourth side plate 72. The third side plate 71 and the fourth side plate 72 are located on the outside of the swing support 90, so that the third side plate 71 and the fourth side plate 72 can form a protection for the swing support 90. The fourth side plate 72 can be provided with a second sensing member 100, and the swing support 90 can be provided with a second driving member 101.

[0165] The swing support 90 includes a fifth side plate 91, a sixth side plate 92, and a second bottom plate. Both the fifth side plate 91 and the sixth side plate 92 are connected to the second bottom plate 93, thereby enclosing the third accommodating portion 90a. Along the first axis P1, two fifth side plates 91 are spaced apart from the sixth side plate 92. The two fifth side plates 91 are located on the same side of the sixth side plate 92. Along the second axis P2, the fourth side plate 72 of the rotating support 70 faces the sixth side plate 92. The second driving member 101 is mounted on the sixth side plate 92. A lens holder 110 is located on the side of the second bottom plate 93 facing the third accommodating portion 90a. Along the first axis P1, the fifth side plates 91 are disposed on either side of the lens holder 110. For example, the lens holder 110 is disposed between the two fifth side plates 91. For example, along the third axis P3 , the first bottom plate 62 of the base 60 is disposed facing the second bottom plate 93 of the rocker support 90 .

[0166] In some examples, the number of the second sensing members 100 and the second driving members 101 can both be two. Along the first axis P1, the two second sensing members 100 are spaced apart on the fourth side plate 72 of the rotating support 70. The position of the second driving member 101 is set in a one-to-one correspondence with the position of the second sensing member 100. The two second driving members 101 can generate driving force simultaneously with the two second sensing members 100 respectively, so that the overall force of the swing support 90 is more balanced, which is beneficial to improve the rotation stability of the swing support 90. It can be understood that the number of the second sensing members 100 and the second driving members 101 is not limited to the above number, but can be set to other numbers as required. For example, the number of the second sensing members 100 and the second driving members 101 can both be more than three, and this application does not limit this.

[0167] In some examples, an induction force can be generated between the second driving member 101 and the second induction member 100 by magnetic induction. Exemplarily, the second induction member 100 can be a magnet. For example, the second induction member 100 can be a permanent magnet. The second induction member 100 includes but is not limited to a neodymium iron boron magnet or an alnico magnet. The second driving member 101 can be a coil. For example, the material of the second driving member 101 can be copper or a copper alloy. When the second driving member 101 is powered on, it is in a working state to generate a magnetic force. When the second driving member 101 is powered off, it is in a stopped state and does not generate a magnetic force. By controlling the magnitude of the current in the second driving member 101, the magnitude of the magnetic force generated by the second driving member 101 can be controlled. The second induction member 100 can sense the change in the current in the second driving member 101, thereby generating a driving force to drive the swing support 90 to drive the swing support 90 to rotate.

[0168] Exemplarily, the rotating support 70 includes a third side plate 71 and a fourth side plate 72 that are intersectingly disposed. The second sensing member 100 is disposed on the fourth side plate 72. The second sensing member 100 can be disposed on a side of the fourth side plate 72 facing the second receiving portion 70a.

[0169] Exemplarily, the rotating support 70 includes a first insulating portion 701 and a first magnetic metal sheet 702. The first insulating portion 701 is arranged on the outer surface of the first magnetic metal sheet 702. The first magnetic metal sheet 702 and the second sensing member 100 can attract each other through magnetic attraction to fix the second sensing member 100 on the fourth side plate 72, so that no additional connection structure is required between the second sensing member 100 and the fourth side plate 72, and the connection method between the two is simple in structure. A receiving recess can be provided on the surface of the first insulating portion 701 facing the swing support 90. The shape of the receiving recess is the same as the shape of the second sensing member 100. The second sensing member 100 can be arranged in the receiving recess, which is conducive to further ensuring the accurate installation position of the second sensing member 100 and can improve the reliability and stability of the connection between the second sensing member 100 and the fourth side plate 72. The surface of the first insulating portion 701 can be the same shape as that of the second sensing element 100 , and can be flush with the surface of the second sensing element 100 , so the first insulating portion 701 does not block the surface of the second sensing element 100 facing the swing support 90 .

[0170] Exemplarily, along the second axis P2 , the first induction element 80 and the second induction element 100 are respectively disposed on two sides of the first magnetic conductive metal sheet 702 .

[0171] In some achievable embodiments, FIG19 schematically illustrates a partially exploded structure of the swing support 90 of the present application. Referring to FIG19 , a second sensing member 100 is provided on the rotating support 70. A position-limiting fixing portion is provided on the swing support 90. A second driving member 101 is provided on the position-limiting fixing portion. The position-limiting fixing portion can limit the second driving member 101, maintaining a stable position of the second driving member 101 and preventing it from shifting, thereby ensuring that the relative positions of the second sensing member 100 and the second driving member 101 are not easily changed.

[0172] Figure 20 schematically illustrates the structure of the first flexible circuit board 160 of the present application. Referring to Figures 18 and 20 , the lens support device 50 further includes a first flexible circuit board 160. The first flexible circuit board 160 is connected to the swing support 90. The first flexible circuit board 160 includes a main body 161, a bent portion 162, and a transition portion 163. The transition portion 163 corresponds to the position-limiting fixing portion. The bent portions 162 are provided at opposite ends of the main body 161 along the first axis P1. Both the main body 161 and the bent portion 162 are connected to the swing support 90. Along the first axis P1, the third accommodating portion 90a is located between the two bent portions 162. A transition portion 163 is provided on each bent portion 162. The second driver 101 is electrically connected to the transition portion 163, thereby enabling the first flexible circuit board 160 to control the current input to the second driver 101.

[0173] Exemplarily, along the second axis P2 , a transition portion 163 is provided on one side of the bent portion 162 .

[0174] Exemplarily, the main body 161 of the first flexible circuit board 160 is located on the side of the swing support 90 facing the base 60. The main body 161 can be connected to the second bottom plate 93 of the swing support 90, and the bent portion 162 can be connected to the fifth side plate 91 of the swing support 90.

[0175] As shown in FIG18 , the lens carrier 50 further includes a first support plate 170. The first support plate 170 is disposed on the side of the main body 161 facing away from the third receiving portion 90 a. The first support plate 170 is connected to the swing support 90. The main body 161 is connected to the surface of the first support plate 170 facing the third receiving portion 90 a. The first support plate 170 provides support for the main body 161, preventing it from bending or deforming.

[0176] In some examples, the main body 161 of the first flexible circuit board 160 can be disposed on the side of the second base plate 93 of the swing support 90 facing away from the third accommodating portion 90a. The first support plate 170 is connected to the second base plate 93, for example, by adhesive or snap-fit ​​connection. Exemplarily, the first support plate 170 can be a magnetically conductive metal structure. For example, the material of the first support plate 170 can include, but is not limited to, steel.

[0177] The lens support device 50 also includes a second support plate 180. The second support plate 180 is disposed on the side of the bent portion 162 facing away from the third receiving portion 90a. The second support plate 180 is connected to the swing support 90. The bent portion 162 is connected to the surface of the second support plate 180 facing the third receiving portion 90a. The second support plate 180 provides support for the bent portion 162, preventing it from bending or deforming.

[0178] In some examples, the bent portion 162 of the first flexible circuit board 160 is located on the side of the fifth side plate 91 of the swing support 90 that faces away from the third accommodating portion 90a. The second support plate 180 is connected to the fifth side plate 91, for example, by bonding or snapping. Exemplarily, the second support plate 180 may be a magnetically conductive metal structure. For example, the material of the second support plate 180 may include, but is not limited to, steel.

[0179] As shown in Figure 19, the fifth side plate 91 has a connected avoidance hole 911 and a receiving space 912. Along the first axis P1, the receiving space 912 is located on the side of the avoidance hole 911 facing away from the third receiving portion 90a. The avoidance hole 911 connects the third receiving portion 90a with the receiving space 912. The avoidance hole 911 is located on the side of the bent portion 162 facing the third receiving portion 90a. The bent portion 162 and the second support plate 180 are both located in the receiving space 912. The area of ​​the bent portion 162 corresponding to the avoidance hole 911 is exposed to the third receiving portion 90a.

[0180] Exemplarily, as shown in Figure 19, the limiting fixing portion includes a fixing groove 90b. The fixing groove 90b is provided on the surface of the swing support 90 facing the rotating support 70. At least part of the second driving member 101 is located in the fixing groove 90b to achieve the installation and fixation of the second driving member 101. For example, the fixing groove 90b is provided on the surface of the swing support 90 facing the fourth side plate 72. Along the second axis P2, the thickness of the second driving member 101 can be the same as the depth of the fixing groove 90b. For example, the swing support 90 includes a sixth side plate 92. The second driving member 101 is provided on the sixth side plate 92. The fixing groove 90b is provided on the surface of the sixth side plate 92 facing the rotating support 70. Specifically, the fixing groove 90b is provided on the surface of the sixth side plate 92 facing the fourth side plate 72.

[0181] The sidewall shape of the fixing groove 90b matches the shape of the side surface of the second driving member 101, so that the second driving member 101 can be aligned with the sidewall of the fixing groove 90b. This helps ensure that the second driving member 101 is positioned with high precision and is not easily displaced within the fixing groove 90b. For example, the second driving member 101 can be polygonal, such as a hexagon. Three sides of the second driving member 101 can be aligned with the sidewall of the fixing groove 90b.

[0182] Two fixing slots 90b are provided on the swing support 90. The two fixing slots 90b are spaced apart along the first axis P1. Each fixing slot 90b can be provided with a second driving member 101.

[0183] At least a portion of the adapter portion 163 is located in the fixing groove 90 b. The second driving member 101 is located on the side of the adapter portion 163 facing the rotating support 70. The adapter portion 163 is located between the second driving member 101 and the sixth side plate 92 of the swing support 90.

[0184] At least a portion of the adapter portion 163 can be located within the fixing groove 90b. The second driving member 101 can be electrically connected to the adapter portion 163. For example, the shape of the sidewalls of the fixing groove 90b matches the shape of the side surface of the adapter portion 163, so that the adapter portion 163 can fit closely with the sidewalls of the fixing groove 90b. This helps ensure that the adapter portion 163 is accurately positioned and installed, and is not easily displaced within the fixing groove 90b.

[0185] As shown in Figures 19 and 20 , the transition portion 163 of the first flexible circuit board 160 can be positioned on one side of the bent portion 162 along the second axis P2. The transition portion 163 of the first flexible circuit board 160 includes an end connection section 1631 and a narrowing section 1632. The end connection section 1631 is positioned within the fixing slot 90b and electrically connected to the second driving member 101. The narrowing section 1632 connects the end connection section 1631 and the bent portion 162. The position-limiting fixing portion also includes a positioning slot 90c. The positioning slot 90c is connected to the fixing slot 90b. The positioning slot 90c extends through the sixth side plate 92 along the second axis P2. The narrowed section 1632 of the adapter part 163 is located in the positioning groove 90c, so that the adapter part 163 and the sixth side plate 92 have a compact structure. At the same time, the narrowed section 1632 is not easy to offset relative to the sixth side plate 92, and the narrowed section 1632 can be protected by the sixth side plate 92 and is not easy to be scratched or collided and damaged.

[0186] The positioning groove 90c of the swing support 90 can correspond to the center hole of the second driving member 101, so that after the second driving member 101 is installed in the fixing groove 90b, the second driving member 101 will not squeeze the narrowing section 1632 of the adapter 163, thereby avoiding the narrowing section 1632 being squeezed and damaged.

[0187] As shown in Figure 19, along the second axis P2, a protrusion 913 is provided at the end of the fifth side plate 91 away from the sixth side plate 92. The protrusion 913 is provided facing the rotating support 70, for example, the protrusion 913 is provided facing the third side plate 71. The accommodating space 912 is located between the protrusion 913 and the sixth side plate 92. Along the first axis P1, the protrusion 913 protrudes from the second support plate 180. The surface of the sixth side plate 92 facing the rotating support 70 and the surface of the protrusion 913 facing the rotating support 70 are both arc-shaped. For example, the surface of the sixth side plate 92 facing the third side plate 71 and the surface of the protrusion 913 facing the third side plate 71 are both arc-shaped, specifically, they can be circular arcs.

[0188] Exemplarily, the side surface of the second driving member 101 has the same shape as the surface of the sixth side plate 92 facing the third side plate 71. The side surface of the second driving member 101 and the surface of the sixth side plate 92 facing the third side plate 71 are flush with each other.

[0189] In some examples, Figure 21 schematically illustrates a partial structure of the lens carrier 50 of the present application. Figure 22 schematically illustrates a partial exploded structure of the lens carrier 50 of the present application. Referring to Figures 21 and 22, the third side plate 71 of the rotating support 70 can be provided with a second sensing member 100, while the swing support 90 can be provided with a second driving member 101. For example, the second sensing member 100 is provided on the third side plate 71 of the rotating support 70, while the second driving member 101 is provided on the fifth side plate 91 of the swing support 90.

[0190] A second sensing member 100 is respectively provided on the two third side plates 71 of the rotating support 70. The second sensing member 100 can be provided on the surface of the third side plate 71 facing the second accommodating portion 70a. The number of second sensing members 100 can be two. A second sensing member 100 is provided on each third side plate 71. A second driving member 101 is respectively provided on the two fifth side plates 91 of the swing support 90. The second driving member 101 can be provided on the side of the fifth side plate 91 facing the third side plate 71. The number of second driving members 101 can be two. A second driving member 101 is provided on each fifth side plate 91. The two second driving members 101 can respectively generate driving force simultaneously with the two second sensing members 100, so that the force on the swing support 90 is more balanced, which is beneficial to improving the rotation stability of the swing support 90.

[0191] Exemplarily, the rotating support 70 includes a third side plate 71 and a fourth side plate 72 that are intersectingly disposed. The second sensing element 100 is disposed on the third side plate 71 .

[0192] The surface of the second sensing member 100 facing away from the third side plate 71 is a concave arc-shaped surface, for example, a concave circular arc surface. Therefore, when the swing support 90 rotates about the second axis P2, a small gap can be maintained between the second sensing member 100 and the second driving member 101, thereby ensuring the stability of the driving force generated by the second driving member 101 and the second sensing member 100, which is conducive to improving the rotational stability of the swing support 90 and the accuracy of the rotation angle.

[0193] The two ends of the first magnetic conductive metal sheet 702 are located on the third side plate 71. The middle portion of the first magnetic conductive metal sheet 702 is located on the fourth side plate 72. The ends of the first magnetic conductive metal sheet 702 and the second inductive element 100 can be attracted to each other through magnetic attraction, thereby fixing the second inductive element 100 to the third side plate 71. As a result, no additional connecting structure is required between the second inductive element 100 and the third side plate 71, and the connection between the two is simple.

[0194] A second driving member 101 is disposed on the fifth side plate 91 of the swing support 90. The surface of the second driving member 101 facing the second sensing member 100 may be an arcuate surface, for example, a circular arc surface, so that a small gap can be maintained between the second sensing member 100 and the second driving member 101 when the swing support 90 rotates about the second axis P2.

[0195] In some examples, as shown in FIG. 22 , the position-limiting and fixing portion includes a clamping portion 914. The clamping portion 914 is located on the side of the adapter portion 163 facing away from the third accommodating portion 90a. The clamping portion 914 faces the rotating support 70, for example, facing the third side plate 71. The second driving member 101 is connected to the clamping portion 914, thereby enabling the second driving member 101 to be fixedly engaged with the rotating support 70 via the clamping portion 914.

[0196] Exemplarily, the fifth side plate 91 includes two spaced apart clamping portions 914 . The two clamping portions 914 are located in the central hole of the second driving member 101 , so that the second driving member 101 and the fifth side plate 91 can be clamped and fixed via the clamping portions 914 .

[0197] Figure 23 schematically illustrates the structure of the first flexible circuit board 160 of the present application. As shown in Figure 23 , the end of the bent portion 162 of the first flexible circuit board 160, facing away from the main body 161, is connected to the adapter portion 163. Along the first axis P1, the adapter portion 163 is located on the side of the bent portion 162 facing away from the third accommodating portion 90a. Both the adapter portion 163 and the bent portion 162 can be located within the accommodating space 912 of the fifth side plate 91. The second driving member 101 is located on the side of the adapter portion 163 facing away from the bent portion 162. Along the first axis P1, the second support plate 180 is located between the adapter portion 163 and the bent portion 162.

[0198] 22 , the lens carrier 50 further includes a third support plate 190. The third support plate 190 is located between the clamping portion 914 and the adapter portion 163. The second driving member 101 is located on a side of the third support plate 190 facing away from the adapter portion 163. The third support plate 190 is connected to the swing support 90.

[0199] Illustratively, the third support plate 190 is connected to the fifth side plate 91. Along the first axis P1, the third support plate 190 is located between the second driver 101 and the adapter 163. The second driver 101 is disposed on the side of the third support plate 190 facing the third side plate 71. The adapter 163 is located between the second support plate 180 and the third support plate 190. The clamping portion 914 can press against the surface of the third support plate 190 facing the second driver 101 to secure the position of the third support plate 190. Illustratively, the third support plate 190 can be a magnetically conductive metal structure. For example, the material of the third support plate 190 can include, but is not limited to, steel.

[0200] In some embodiments, the swing support 90 is rotatably connected to the fourth side plate 72 of the rotating support 70. The lens supporting device 50 also includes a guide rail. The guide rail is disposed between the fourth side plate 72 and the sixth side plate 92 along the second axis P2. The swing support 90 rotates relative to the rotating support 70 about the second axis P2 via the guide rail. The guide rail reduces rotational resistance between the swing support 90 and the rotating support 70, ensures stable rotation of the swing support 90, and improves rotational accuracy.

[0201] In some examples, as shown in Figures 17 and 18 , the guide rail includes a curved rail 200, an annular rail 201, and ball bearings 202. The curved rail 200 is provided on the fourth side plate 72 of the rotating support 70. The two curved rails 200 are symmetrically arranged about the second axis P2. The annular rail 201 is provided on the sixth side plate 92 of the swing support 90. Ball bearings 202 are provided between the curved rail 200 and the annular rail 201. Both the curved rail 200 and the annular rail 201 extend around the second axis P2. For example, the central axes of the curved rail 200 and the annular rail 201 coincide with the second axis P2. When the swing support 90 rotates relative to the rotating support 70, it drives the ball bearings 202 to roll. The ball bearings 202 effectively reduce the rotational resistance of the swing support 90 relative to the rotating support 70, allowing the second actuator to rotate the swing support 90 with relatively less driving force.

[0202] For example, an arcuate groove is provided on the surface of the fourth side plate 72 of the rotating support 70 facing the sixth side plate 92 of the swing support 90. This arcuate groove forms an arcuate slide rail 200. An annular groove is provided on the surface of the sixth side plate 92 of the swing support 90 facing the fourth side plate 72 of the rotating support 70. This annular groove forms an annular slide rail 201. A ball bearing 202 is disposed between the arcuate groove and the annular groove.

[0203] For example, the ball 202 may be a spherical structure.

[0204] In some examples, a second sensing member 100 is provided on the fourth side plate 72 of the rotating support 70. The swing support 90 includes a second insulating portion 901 and a second magnetic conductive metal sheet 902. The second insulating portion 901 is provided on the outer surface of the second magnetic conductive metal sheet 902. The second magnetic conductive metal sheet 902 and the second sensing member 100 can attract each other through magnetic attraction. Under the action of the magnetic attraction between the second magnetic conductive metal sheet 902 and the second sensing member 100, the swing support 90 and the rotating support 70 squeeze the ball 202 against each other, so that the swing support 90 and the rotating support 70 are rotatably connected, and the ball 202 will not fall out from between the swing support 90 and the rotating support 70. The swing support 90 and the rotating support 70 can be connected under the action of the magnetic attraction force between the second magnetic conductive metal sheet 902 and the second sensing element 100, so that no additional connecting structure is required between the swing support 90 and the rotating support 70. Therefore, the connection method between the swing support 90 and the rotating support 70 is simple, and the number of parts used is small, which is conducive to improving the compactness of the structure and reducing the difficulty of assembly.

[0205] For example, there may be two second sensing members 100. Along the first axis P1, the two second sensing members 100 are spaced apart, and the arc-shaped slide rail 200 is located between the two second sensing members 100. The two second sensing members 100 may be symmetrically arranged relative to the second axis P2.

[0206] For example, an annular groove is provided on the surface of the sixth side plate 92 of the swing support 90 that faces the fourth side plate 72 of the rotating support 70. This annular groove forms the annular guide rail 201. The area of ​​the second magnetic conductive metal sheet 902 of the swing support 90 corresponding to the annular groove can be exposed in the annular groove, so that the ball bearing 202 presses against the second magnetic conductive metal sheet 902.

[0207] Along the second axis P2, the swing support 90 and the rotating support 70 are spaced apart, meaning they do not contact each other. Therefore, there is no direct frictional resistance between the swing support 90 and the rotating support 70. As a result, the swing support 90 only needs to overcome the rolling resistance of the balls 202 during rotation. This improves the rotational accuracy of the swing support 90 and reduces the likelihood of rotational impact forces caused by frictional resistance during the start or stop phases of rotation. This ensures stable and precise movement of the lens support 110.

[0208] Illustratively, the swing support 90 is provided with a fixing groove 90b. For example, the fixing groove 90b is provided on the sixth side plate 92. The portion of the second magnetic conductive metal sheet 902 corresponding to the fixing groove 90b can be visible. The adapter portion 163 of the first flexible circuit board 160 can be connected to the surface of the second magnetic conductive metal sheet 902 facing the second driving member 101.

[0209] For example, as shown in FIG. 19 , the swing support 90 is provided with a fixing slot 90 b. The lens support device 50 further includes a magnetic conductive sheet 210. The magnetic conductive sheet 210 can be disposed on the bottom wall of the fixing slot 90 b. For example, the magnetic conductive sheet 210 can be bonded to the bottom wall of the fixing slot 90 b. For example, the bottom wall of the fixing slot 90 b is perpendicular to the second axis P2. The adapter portion 163 of the first flexible circuit board 160 can be connected to the surface of the magnetic conductive sheet 210 facing the second driving member 101. For example, the adapter portion 163 can be bonded to the magnetic conductive sheet 210. The second driving member 101 can be bonded to the magnetic conductive sheet 210. The area of ​​the adapter portion 163 can be smaller than that of the magnetic conductive sheet 210, such that the adapter portion 163 does not completely cover the magnetic conductive sheet 210. The magnetic conductive sheet 210 and the second magnetic conductive metal sheet 902 can be provided independently. For example, the material of the magnetic conductive sheet 210 includes, but is not limited to, steel.

[0210] In other examples, as shown in FIG21 , a second sensing element 100 is provided on the third side plate 71 of the rotating support 70. A second driving element 101 is provided on the fifth side plate 91 of the swing support 90. The swing support 90 includes a second insulating portion 901 and a second magnetic conductive metal sheet 902. The second insulating portion 901 is disposed on the outer surface of the second magnetic conductive metal sheet 902. The lens support device 50 also includes a magnetic plate 220. The magnetic plate 220 is disposed on the side of the fourth side plate 72 facing the swing support 90. The second magnetic conductive metal sheet 902 and the magnetic plate 220 can attract each other through magnetic attraction, thereby connecting the swing support 90 and the rotating support 70. Under the action of the magnetic attraction between the second magnetic conductive metal sheet 902 and the magnetic plate 220, the swing support 90 and the rotating support 70 squeeze the ball bearing 202 against each other, thereby achieving a rotatable connection between the swing support 90 and the rotating support 70, and preventing the ball bearing 202 from falling out from between the swing support 90 and the rotating support 70. The swing support 90 and the rotating support 70 can be connected under the magnetic attraction of the second magnetic conductive metal sheet 902 and the magnetic plate 220, so that no additional connecting structure is required between the swing support 90 and the rotating support 70. Therefore, the connection method between the swing support 90 and the rotating support 70 is simple, and the number of parts used is small, which is conducive to improving the compactness of the structure and reducing the difficulty of assembly.

[0211] Illustratively, the magnetic plate 220 may include, but is not limited to, a permanent magnet, such as a neodymium iron boron magnet or an alnico magnet.

[0212] For example, there may be two magnetic plates 220. Along the first axis P1, the two magnetic plates 220 are spaced apart, and the arc-shaped slide rail 200 is located between the two magnetic plates 220. The two magnetic plates 220 may be symmetrically arranged relative to the second axis P2.

[0213] In some embodiments, as shown in FIG. 18 , the lens support device 50 further includes a second angle sensor 230 . The second angle sensor 230 is disposed on the swing support 90 . The second angle sensor 230 is configured to detect the rotation angle of the swing support 90 about the second axis P2 . When the second driving member 101 and the second sensing member 100 jointly drive the swing support 90 to rotate, the second angle sensor 230 can be used to detect the rotation angle of the swing support 90 about the second axis P2 , thereby facilitating control of the rotation angle of the swing support 90 and improving the accuracy of the rotation angle of the swing support 90 .

[0214] In some examples, the second angle sensor 230 is in communication with the central processing unit. The second angle sensor 230 can detect the rotation angle of the swing support 90 in real time and control the rotation angle of the swing support 90 by controlling the driving force generated by the second driving member 101 and the second sensing member 100.

[0215] In some examples, the second sensing element 100 may be a magnet, the second angle sensor 230 may be a Hall sensor, the second driving element 101 may be a coil, and the second angle sensor 230 may be located in a central hole of the second driving element 101 .

[0216] Exemplarily, the second angle sensor 230 is disposed on the surface of the adapter portion 163 of the first flexible printed circuit board 160 that faces the second driver 101. The second driver 101 is disposed on the sixth side plate 92 of the swing support 90. The second angle sensor 230 can be connected to the sixth side plate 92. The second angle sensor 230 can be electrically connected to the adapter portion 163.

[0217] For example, as shown in FIG22 , the second angle sensor 230 is disposed on the surface of the adapter portion 163 of the first flexible printed circuit board 160 facing the second driver 101. The second driver 101 is disposed on the fifth side plate 91 of the swing support 90. The second angle sensor 230 can be connected to the fifth side plate 91. A third support plate 190 is disposed between the second driver 101 and the adapter portion 163. The third support plate 190 can have a through hole. This through hole is provided to allow the second angle sensor 230 to pass through.

[0218] In some achievable embodiments, Figure 24 schematically shows the side view structure of the lens supporting device 50 of the present application. As shown in Figure 24, the lens supporting device 50 also includes a brake assembly 150. The brake assembly 150 is arranged between the base 60 and the swing support 90. The brake assembly 150 is used to brake the swing support 90. When the swing support 90 rotates to a predetermined angle, the brake assembly 150 brakes the swing support 90 so that the swing support 90 is stably maintained in the current position and is not prone to shaking, thereby reducing the possibility of the swing support 90 being offset and deviating from the predetermined position, which is beneficial to improving the position stability of the swing support 90, thereby ensuring that the position of the lens remains stable. After the brake assembly 150 brakes the swing support 90, the second driving member 101 can be in a stopped state, and at this time, no driving force is generated between the second driving member 101 and the second sensing member 100. When the swing support 90 needs to rotate to adjust its position, the brake assembly 150 releases the swing support 90 , and the second driving member 101 and the second sensing member 100 generate a driving force to drive the swing support 90 to rotate.

[0219] In some examples, the brake assembly 150 includes a stopper 151 and a stopper 152. The stopper 151 is provided on one of the swing support 90 and the base 60, and the stopper 152 is provided on the other. The stopper 151 and the stopper 152 engage or disengage to brake or release the swing support 90. When the swing support 90 rotates to a predetermined angle, the stopper 151 and the stopper 152 engage to brake the swing support 90. When the stopper 151 and the stopper 152 are engaged, relative movement between the stopper 151 and the stopper 152 is unlikely, further improving the positional stability of the swing support 90.

[0220] Exemplarily, a limiting portion 151 is provided on the swing support 90 , and a limiter 152 is provided on the base 60 .

[0221] Illustratively, the base 60 includes a first bottom plate 62. The swing support 90 includes a second bottom plate 93. Along the third axis P3, the second bottom plate 93 of the swing support 90 is disposed facing the first bottom plate 62 of the base 60. A stopper 152 is provided on the first bottom plate 62 of the base 60. A stopper 151 is provided on the second bottom plate 93 of the swing support 90. The stopper 151 and the stopper 152 are located between the first bottom plate 62 and the second bottom plate 93.

[0222] In some examples, the limiting portion 151 includes a limiting groove. Multiple limiting grooves are distributed around the second axis P2. Multiple limiting grooves are arranged in an arc shape. Figure 25 schematically shows a partial structure of the lens supporting device 50 of the present application. Figure 26 is an enlarged view of point G in Figure 9. As shown in Figures 25 and 26, the limiter 152 includes a limiting spring 1521 and an actuator 1522. The actuator 1522 is used to drive the limiting spring 1521 to engage or disengage with the limiting groove. For example, the limiting spring 1521 can engage or disengage with any one of the limiting grooves.

[0223] Taking the engagement state of the limiting spring piece 1521 and the limiting groove as an example, when the swing support 90 needs to be rotated to adjust its position, the actuator 1522 applies a force to the limiting spring piece 1521, causing it to move away from the limiting groove and exit from the limiting groove, thereby releasing the swing support 90. When the swing support 90 rotates to a predetermined angle, the actuator 1522 releases the limiting spring piece 1521, which then resets and re-enters the limiting groove, thereby locking the limiting spring piece 1521 into the limiting groove and braking the swing support 90. After the limiting spring piece 1521 is engaged with the limiting groove, relative movement between the limiting spring piece 1521 and the limiting groove is unlikely to occur, thereby limiting the forward or reverse rotation of the swing support 90 and preventing the swing support 90 from shifting.

[0224] There is a spacing between two adjacent limiting grooves. When one of the two adjacent limiting grooves engages the limiting spring 1521, the swing support 90 is in the first position. When the other one engages the limiting spring 1521, the swing support 90 is in the second position. Therefore, by adjusting the spacing between the two adjacent limiting grooves, the rotation angle of the swing support 90 from the first position to the second position can be controlled. For example, the multiple limiting grooves are evenly distributed around the second axis P2.

[0225] 22 , the swing support 90 includes a second insulating portion 901 and a second magnetic conductive metal sheet 902 . The second insulating portion 901 is provided on the outer surface of the second magnetic conductive metal sheet 902 .

[0226] Specifically, the second insulating portion 901 may be provided with a limiting groove that passes through the second insulating portion 901 along the second axis P2.

[0227] Specifically, the limiting groove can pass through the second magnetic conductive metal sheet 902 along the second axis P2. Alternatively, the limiting groove can pass through the second insulating portion 901 and the second magnetic conductive metal sheet 902 along the second axis P2. The second magnetic conductive metal sheet 902 itself has a relatively large mechanical strength. Therefore, when the limiting spring 1521 and the limiting groove are engaged, the second magnetic conductive metal sheet 902 is not easily deformed under the action of the limiting spring 1521. In addition, when the limiting spring 1521 and the limiting groove are frequently engaged or separated, the second magnetic conductive metal sheet 902 is not prone to friction loss, which may cause the limiting groove to expand or become larger in size. This reduces the possibility that the limiting groove expands or becomes larger in size, resulting in poor engagement between the limiting spring 1521 and the limiting groove, or a gap between the two, and is conducive to ensuring that the limiting spring 1521 and the limiting groove maintain good matching accuracy for a long time.

[0228] For example, as shown in FIG26 , a curved plate 90d is provided on the surface of the swing support 90 facing the base 60. For example, a curved plate 90d is provided on the surface of the second bottom plate 93 facing the rotating support 70. The central axis of the curved plate 90d can coincide with the second axis P2. A retaining groove is provided on the curved plate 90d. The retaining groove extends through the curved plate 90d along the second axis P2.

[0229] The second insulating portion 901 forms an arc-shaped plate 90d at the bottom of the swing support 90. The limiting groove passes through the second insulating portion 901.

[0230] Alternatively, the second magnetic conductive metal sheet 902 forms an arc-shaped plate 90d at the bottom of the swing support 90. The limiting groove passes through the second magnetic conductive metal sheet 902.

[0231] Alternatively, the second insulating portion 901 and the second magnetic conductive metal sheet 902 form an arc-shaped plate 90d at the bottom of the swing support 90. The limiting groove passes through the second insulating portion 901 and the second magnetic conductive metal sheet 902.

[0232] For example, the limiting spring piece 1521 has a protrusion 1521d. The limiting spring piece 1521 can be engaged with the limiting groove through the protrusion 1521d. The protrusion 1521d can be a strip-shaped structure extending along the second axis P2.

[0233] The top surface of the protrusion 1521d facing the limiting groove can be a flat surface 732, so that the height of the protrusion 1521d is the same at all positions. Alternatively, the top surface of the protrusion 1521d facing the limiting groove includes a flat surface 732 and a raised surface, so that the height of the protrusion 1521d varies.

[0234] For example, as shown in Figures 25 and 26, the limiting spring piece 1521 includes a first extension section 1521a, a second extension section 1521b, and a third extension section 1521c. The first extension section 1521a and the third extension section 1521c are respectively disposed on either side of the second extension section 1521b. The first extension section 1521a is connected to the base 60. A gap is provided between the third extension section 1521c and the base 60. The third extension section 1521c is configured to engage with or disengage from the limiting groove. For example, the third extension section 1521c includes a protrusion 1521d. The third extension section 1521c can engage with or disengage from the limiting groove via the protrusion 1521d.

[0235] For example, the angle between the first extension section 1521a and the second extension section 1521b can be an obtuse angle. The angle between the third extension section 1521c and the second extension section 1521b can also be an obtuse angle. The first extension section 1521a and the third extension section 1521c can be arranged parallel to each other. After the limiting spring piece 1521 is connected to the first base plate 62 via the first extension section 1521a, the second extension section 1521b is inclined, and a gap is formed between the third extension section 1521c and the first base plate 62.

[0236] Illustratively, the brake assembly 150 further includes a limiting member 153. The limiting member 153 is used to limit the limiting spring piece 1521 along the first axis P1. When the limiting spring piece 1521 is subjected to a force along the first axis P1 and swings, the limiting member 153 can block the limiting spring piece 1521, thereby effectively reducing the swing amplitude of the limiting spring piece 1521 along the first axis P1 and reducing the possibility that the limiting spring piece 1521 will not be able to accurately engage with the limiting groove due to deformation and displacement of the limiting spring piece 1521 from the predetermined engaging position. Illustratively, the limiting member 153 can be a plate-shaped structure. The limiting spring piece 1521 and the limiting member 153 are disposed on the first bottom plate 62 of the base 60. Illustratively, a limiting hole 1521e can be provided in the second extension section 1521b of the limiting spring piece 1521. The limiting hole 1521e extends through the second extension section 1521b along the third axis P3. The limiting member 153 is passed through the limiting hole 1521e.

[0237] Exemplarily, the limiting spring 1521 may be a magnetically conductive structure. For example, the material of the limiting spring 1521 may include, but is not limited to, steel. The actuator 1522 may be an electromagnet. The actuator 1522 may be disposed between the limiting spring 1521 and the base 60. The actuator 1522 is powered on or off to drive the limiting spring 1521 to engage or disengage with the limiting groove. For example, the actuator 1522 may be located between the third extension section 1521c and the first base plate 62. When the actuator 1522 is powered on, a magnetic attraction force is generated, which attracts the third extension section 1521c, causing it to move closer to the actuator 1522 and separate from the limiting groove. When the actuator 1522 is powered off, the actuator 1522 releases the third extension section 1521c, causing it to move away from the actuator 1522 and engage with the limiting groove.

[0238] The first bottom plate 62 of the base 60 includes a second insulating frame 621 and a second magnetic conductive metal plate 622. The first insulating frame 611 of the first side plate 61 can be integrally formed with the second insulating frame 621 of the first bottom plate 62. The second magnetic conductive metal plate 622 is disposed on the second insulating frame 621 and covers the center hole of the second insulating frame 621. The stopper 152 can be disposed on the surface of the second magnetic conductive metal plate 622 facing the first accommodating portion 60a. For example, the material of the second insulating frame 621 can include, but is not limited to, plastic. The material of the second magnetic conductive metal plate 622 can include, but is not limited to, steel. The stopper spring 1521 can be disposed on the second magnetic conductive metal plate 622. For example, the first extension section 1521a of the stopper spring 1521 can be connected to the second magnetic conductive metal plate 622. The first extension section 1521a can be welded, bonded, or connected to the second magnetic conductive metal plate 622 using fasteners. The actuator 1522 can be disposed on the second magnetically conductive metal plate 622 and positioned between the third extension section 1521c and the second magnetically conductive metal plate 622. When the actuator 1522 is energized, it generates a magnetic attraction force, which attracts the third extension section 1521c, causing the third extension section 1521c to move closer to the actuator 1522 and separate from the retaining groove. When the actuator 1522 is de-energized, the actuator 1522 releases the third extension section 1521c, causing it to move away from the actuator 1522 and engage with the retaining groove.

[0239] For example, actuator 1522 may be a shape memory alloy component. Position-limiting spring 1521 is connected to actuator 1522. Actuator 1522 can be retracted or retracted when powered on or off. Powering on or off actuator 1522 drives position-limiting spring 1521 to engage or disengage with the position-limiting groove. Therefore, actuator 1522, which drives position-limiting spring 1521, has a simple structure, reducing the number of components, simplifying assembly, and conserving installation space.

[0240] One end of the actuator 1522 can be connected to the third extension section 1521c of the limiting spring 1521, and the other end can be connected to the first extension section 1521a, the end of the second extension section 1521b near the first extension section 1521a, or the first base plate 62. The actuator 1522 is located on the side of the limiting spring 1521 facing the first base plate 62. When the actuator 1522 is energized and retracted, the actuator 1522 can drive the third extension section 1521c to move closer to the first base plate 62 and separate from the limiting groove. When the actuator 1522 is de-energized, the actuator 1522 returns to its original length and releases the third extension section 1521c, allowing the third extension section 1521c to move away from the second side plate 63 and engage with the limiting groove.

[0241] In some possible implementations, the third driver is used to rotate the lens holder 110. When a user uses the electronic device 10 to take a photo and the electronic device 10 shakes, the third driver can drive the lens holder 110 to rotate in a direction opposite to the shaking direction, so that the lens holder 110 remains relatively in its current position, thereby achieving lens anti-shake.

[0242] In some examples, the third driver includes a first sub-driver and a second sub-driver. Figures 27 and 28 schematically illustrate a partial structure of the lens support device 50 of the present application. As shown in Figures 27 and 28, the first sub-driver includes a first sub-sensor 120 and a first sub-driver 121. The first sub-sensor 120 is provided on one of the swing support 90 and the lens support 110, while the first sub-driver 121 is provided on the other. The first sub-driver 121 and the first sub-sensor 120 interact to drive the lens support 110 to rotate relative to the swing support 90 about the third axis P3. Figure 29 schematically illustrates a partial structure of the lens support device 50 of the present application. As shown in Figures 28 and 29, the second sub-driver includes a second sub-sensor 122 and a second sub-driver 123. The second sub-sensor 122 is provided on one of the swing support 90 and the lens support 110, while the second sub-driver 123 is provided on the other. The second sub-driving member 123 and the second sub-sensing member 122 interact with each other to drive the lens support 110 to rotate relative to the swing support 90 around the first axis P1.

[0243] The first sub-driver and the second sub-driver can work independently. When at least one of the first sub-driver and the second sub-driver is in the working state, it can drive the lens support 110 to rotate to achieve lens anti-shake.

[0244] In some examples, the first sub-sensing member 120 and the second sub-sensing member 122 are both disposed on the lens support 110 . The first sub-driving member 121 and the second sub-driving member 123 are both disposed on the swing support 90 .

[0245] Illustratively, the swing support 90 includes a fifth side plate 91, a sixth side plate 92, and a second bottom plate 93 connected to each other. Along the first axis P1, the two fifth side plates 91 are spaced apart from the sixth side plate 92. The lens support 110 is located between the two fifth side plates 91, thereby providing protection for the lens support 110 from the outside thereof. A first sub-driver 121 is provided on the side of the fifth side plate 91 facing the third accommodating portion 90a, while a first sub-sensor 120 is correspondingly provided on the lens support 110. A second sub-driver 123 is provided on the side of the second bottom plate 93 facing the third accommodating portion 90a, while a second sub-sensor 122 is correspondingly provided on the lens support 110.

[0246] The lens holder 110 includes a seventh side plate and a third bottom plate connected to each other. The seventh side plate 111 and the third bottom plate 112 of the lens holder 110 can be combined to form a lens receiving portion 110a. Along the first axis P1, two seventh side plates 111 are spaced apart from the third bottom plate 112. Along the first axis P1, the fifth side plate 91 of the swing support 90 is located on one side of the seventh side plate 111 of the lens holder 110. Along the second axis P2, the sixth side plate 92 of the swing support 90 is located on one side of the third bottom plate 112 of the lens holder 110. Along the third axis P3, the second bottom plate 93 of the swing support 90 is located on one side of the third bottom plate 112 of the lens holder 110. A first sub-sensor 120 is provided on the seventh side plate 111 of the lens holder 110, while a second sub-sensor 122 is provided on the third bottom plate 112 of the lens holder 110.

[0247] Illustratively, the surface of the third base plate 112 facing the lens receiving portion 110a is an inclined positioning surface. The inclined positioning surface of the third base plate 112 intersects the second axis P2. In the embodiment where the lens is a prism 300, the reflective surface 302 of the prism 300 is aligned with the inclined positioning surface of the third base plate 112.

[0248] When the first sub-driving member 121 is in operation, mutual induction can occur between the first sub-driving member 121 and the first sub-sensing member 120, thereby generating an induction force between the first sub-driving member 121 and the first sub-sensing member 120. This induction force can serve as the driving force for rotating the lens holder 110. The first sub-driving member 121 and the first sub-sensing member 120 are spaced apart, i.e., the first sub-driving member 121 and the first sub-sensing member 120 do not contact each other.

[0249] When the second sub-driving member 123 is in operation, it senses the second sub-sensing member 122, thereby generating an inductive force on the second sub-sensing member 122. The inductive force of the second sub-sensing member 122 can serve as the driving force for rotating the lens holder 110. The second sub-driving member 123 and the second sub-sensing member 122 are spaced apart, i.e., they do not contact each other.

[0250] Therefore, no transmission structure is required to transmit the force between the first sub-driving member 121 and the first sub-sensing member 120, and the second sub-driving member 123 and the second sub-sensing member 122, so that there is no friction resistance between the first sub-driving member 121 and the first sub-sensing member 120, and the second sub-driving member 123 and the second sub-sensing member 122, which is beneficial to reducing the possibility of rotational impact force occurring in the lens support 110 at the start or stop of rotation due to the existence of frictional resistance, thereby ensuring that the position movement process of the lens support 110 is stable and the position movement accuracy is high.

[0251] In some examples, an inductive force can be generated between the first sub-driver 121 and the first sub-sensor 120 through magnetic induction. For example, the first sub-sensor 120 can be a magnet. For example, the first sub-sensor 120 can be a permanent magnet. The first sub-sensor 120 includes, but is not limited to, a neodymium iron boron magnet or an alnico magnet. The first sub-driver 121 can be a coil. For example, the material of the first sub-driver 121 can be copper or a copper alloy. When powered on, the first sub-driver 121 is in an operating state, generating a magnetic force. When powered off, the first sub-driver 121 is in a stopped state, generating no magnetic force. By controlling the current in the first sub-driver 121, the magnitude of the magnetic force generated by the first sub-driver 121 can be controlled. The first sub-sensor 120 can sense changes in the current in the first sub-driver 121, thereby generating a driving force to drive the lens holder 110, thereby driving the lens holder 110 to rotate.

[0252] In some examples, the induction force can be generated between the second sub-driver 123 and the second sub-sensor 122 through magnetic induction. For example, the second sub-sensor 122 can be a magnet. For example, the second sub-sensor 122 can be a permanent magnet. The second sub-sensor 122 includes, but is not limited to, a neodymium iron boron magnet or an alnico magnet. The second sub-driver 123 can be a coil. For example, the material of the second sub-driver 123 can be copper or a copper alloy. When the second sub-driver 123 is powered on, it is in an operating state, generating a magnetic force. When the second sub-driver 123 is powered off, it is in a stopped state, generating no magnetic force. By controlling the current in the second sub-driver 123, the magnitude of the magnetic force generated by the second sub-driver 123 can be controlled. The second sub-sensor 122 can sense changes in the current in the second sub-driver 123, thereby generating a driving force to drive the lens holder 110, thereby driving the lens holder 110 to rotate.

[0253] In some examples, FIG30 schematically shows a partial cross-sectional structure of the lens supporting device 50 of the present application. Referring to FIG27, FIG29 and FIG30, the lens support 110 includes a third insulating portion 110b and a third magnetic conductive metal sheet 110c. The third insulating portion 110b is provided on the outer surface of the third magnetic conductive metal sheet 110c. The first sub-sensor 120 and the second sub-sensor 122 can be attracted to each other by the third magnetic conductive metal sheet 110c through magnetic attraction to fix the first sub-sensor 120 and the second sub-sensor 122 to the lens support 110, so that no additional connection structure is required between the first sub-sensor 120 and the second sub-sensor 122 and the lens support 110, making the connection structure simple.

[0254] Illustratively, the lens holder 110 includes a seventh side plate 111 and a third bottom plate 112. Third magnetic conductive metal sheets 110c are disposed on each of the seventh side plate 111 and the third bottom plate 112, respectively. A first sub-sensor 120 is disposed on the surface of the seventh side plate 111 facing the fifth side plate 91. A second sub-sensor 122 is disposed on the surface of the third bottom plate 112 facing the second bottom plate 93.

[0255] For example, the material of the third insulating portion 110b may include, but is not limited to, plastic. The material of the third magnetic conductive metal sheet 110c may include, but is not limited to, steel.

[0256] In some examples, the swing support 90 includes a fifth side plate 91 and a second bottom plate 93. A first sub-driver 121 is connected to the fifth side plate 91. A second sub-driver 123 is connected to the second bottom plate 93. The lens support device 50 also includes a first flexible printed circuit board 160. The fifth side plate 91 has a clearance hole 911. The first sub-driver 121 is disposed within the clearance hole 911 and is disposed on a surface of the bent portion 162 of the first flexible printed circuit board 160 that faces the third accommodating portion 90a. The first sub-driver 121 can be electrically connected to the bent portion 162 of the first flexible printed circuit board 160.

[0257] The second base plate 93 has a mounting hole 931 (see FIG. 28 ). The mounting hole 931 extends through the second base plate 93 along the third axis P3. The second sub-driver 123 is disposed within the mounting hole 931. The second sub-driver 123 is disposed on a surface of the main body 161 of the first flexible printed circuit board 160 that faces the third accommodating portion 90a. The second sub-driver 123 is electrically connected to the main body 161 of the first flexible printed circuit board 160.

[0258] In some embodiments, as shown in Figures 28 and 30 , the lens support device 50 further includes a third angle sensor 240 and a fourth angle sensor 250. The third angle sensor 240 is disposed on the fifth side plate 91 of the swing support 90. The third angle sensor 240 is used to detect the rotation angle of the lens support 110 about the third axis P3. The fourth angle sensor 250 is disposed on the second bottom plate 93 of the swing support 90. The fourth angle sensor 250 is used to detect the rotation angle of the lens support 110 about the first axis P1.

[0259] When the second driver drives the lens holder 110 to rotate, the third angle sensor 240 and the fourth angle sensor 250 can be used to detect the rotation angles of the lens holder 110 around the third axis P3 and the first axis P1, respectively, thereby facilitating the control of the rotation angle of the lens holder 110 and improving the accuracy of the rotation angle of the lens holder 110.

[0260] In some examples, the third angle sensor 240 and the fourth angle sensor 250 can both be in communication with the central processing unit. The third angle sensor 240 and the fourth angle sensor 250 can detect the rotation angle of the lens holder 110 in real time and control the driving force generated by the third actuator to control the rotation angle of the lens holder 110.

[0261] In some examples, the first sub-sensing element 120 and the second sub-sensing element 122 can both be magnets. The third angle sensor 240 and the fourth angle sensor 250 can both be Hall sensors. The first sub-driving element 121 and the second sub-driving element 123 can both be coils. The third angle sensor 240 and the fourth angle sensor 250 can be disposed within the center holes of the corresponding first sub-driving element 121 and the second sub-driving element 123.

[0262] For example, the first sub-driver 121 is disposed on the fifth side plate 91 of the swing support 90. The third angle sensor 240 can be connected to the fifth side plate 91. For example, the third angle sensor 240 can be disposed on the surface of the bent portion 162 of the first flexible printed circuit board 160 facing the third receiving portion 90a. The third angle sensor 240 can be electrically connected to the bent portion 162. The third angle sensor 240 is disposed corresponding to the center hole of the first sub-driver 121.

[0263] The second sub-driver 123 is mounted on the second base plate 93 of the swing support 90. A fourth angle sensor 250 can be connected to the second base plate 93. For example, the fourth angle sensor 250 can be mounted on the surface of the main body 161 of the first flexible printed circuit board 160 that faces the third receiving portion 90a. The fourth angle sensor 250 can be electrically connected to the main body 161. The fourth angle sensor 250 is positioned corresponding to the center hole of the second sub-driver 123.

[0264] In some achievable embodiments, as shown in Figures 29 and 30 , the sixth side plate 92 of the lens holder 110 is provided with a columnar body 921. For example, the axis of the columnar body 921 may coincide with the second axis P2. The lens holder 110 is rotatably connected to the columnar body 921. The lens holder 110 includes a mating hole 110d. The columnar body 921 is pluggably engaged with the mating hole 110d. A gap is provided between the columnar body 921 and the mating hole 110d of the lens holder 110, so that when the third actuator drives the lens holder 110 to rotate, the lens holder 110 can move relative to the columnar body 921.

[0265] In some examples, a sphere 400 is disposed between the columnar body 921 and the bottom wall of the mating hole 110d. The lens supporting device 50 further includes an elastic member 260. The elastic member 260 connects the sixth side plate 92 and the lens holder 110. The elastic member 260 applies a force along the second axis P2 to the lens holder 110, causing the lens holder 110 and the columnar body 921 to press against the sphere 400, thereby preventing the sphere 400 from dislodging from between the lens holder 110 and the columnar body 921.

[0266] The swing support 90 and the lens support 110 are spaced apart, meaning they do not contact each other. Consequently, there is no frictional resistance between the swing support 90 and the lens support 110, which improves the rotational accuracy of the lens support 110. This also reduces the likelihood of rotational impact forces caused by frictional resistance during the lens support 110's initial or final rotation, thereby ensuring stable and precise movement of the lens support 110. The simple connection between the swing support 90 and the lens support 110 reduces the number of components used, improving structural compactness and reducing assembly complexity.

[0267] Illustratively, the lens holder 110 includes a third insulating portion 110b and a third magnetically conductive metal sheet 110c. The sphere 400 presses against the surface of the third magnetically conductive metal sheet 110c facing the mating hole 110d, i.e., the sphere 400 is located between the columnar body 921 and the third magnetically conductive metal sheet 110c. The third magnetically conductive metal sheet 110c has considerable mechanical strength, so the elastic member 260 tensions the lens holder 110, preventing deformation of the third magnetically conductive metal sheet 110c when the sphere 400 applies force to it.

[0268] For example, the end surface of the columnar body 921 facing the third magnetic conductive metal sheet 110c and the third magnetic conductive metal sheet 110c are both provided with recesses. A portion of the sphere 400 is located within the recess, so that the columnar body 921 and the third magnetic conductive metal sheet 110c can restrain the sphere 400, thereby reducing the possibility of positional displacement of the sphere 400.

[0269] In some examples, as shown in Figures 28 and 30 , the elastic member 260 may be a leaf spring. The elastic member 260 includes an edge connection portion 261, a deformable portion 262, and a middle connection portion 263. The deformable portion 262 of the elastic member 260 connects the edge connection portion 261 and the middle connection portion 263. The middle connection portion 263 of the elastic member 260 is located between the two edge connection portions 261. The edge connection portion 261 of the elastic member 260 is connected to the sixth side plate 92 of the swing support 90. For example, the edge connection portion 261 of the elastic member 260 may be bonded to or fastened to the sixth side plate 92. The middle connection portion 263 of the elastic member 260 is connected to the lens support 110, for example, to the sidewall of the third base plate 112 of the lens support 110 facing the sixth side plate 92. For example, the middle connection portion 263 of the elastic member 260 may be bonded to or fastened to the third base plate 112. The deformable portion 262 of the elastic member 260 can apply tensile stress toward the sixth side plate 92 of the swing support 90 to the lens support 110 through the intermediate connecting portion 263 , so that the lens support 110 can be pressed tightly against the sphere 400 .

[0270] When the third driver drives the lens holder 110 to rotate about the first axis P1 and / or the third axis P3, the lens holder 110 can cause the deformable portion 262 to deform accordingly, thereby accumulating elastic potential energy. When the third driver stops applying the driving force to the lens holder 110 or applies a reverse force to the lens holder 110, the deformable portion 262 can release the elastic potential energy, thereby applying a force to the lens holder 110 to force the lens holder 110 to rotate in the reverse direction.

[0271] For example, the deformable portion 262 may include a plurality of mutually perpendicular bent sections. One end of the deformable portion 262 is connected to the edge connection portion 261, and the other end is connected to the middle connection portion 263. Two or more deformable portions 262 may be provided between the edge connection portion 261 and the middle connection portion 263.

[0272] Illustratively, the edge connection portion 261, the deformable portion 262, and the intermediate connection portion 263 are arranged along the first axis P1. The intermediate connection portion 263 may be an annular structure. The columnar body 921 is inserted through the center hole of the intermediate connection portion 263. Along the second axis P2, the elastic member 260 may be disposed on the side of the sixth side plate 92 of the swing support 90 that faces the third accommodating portion 90a.

[0273] Figures 31 and 32 schematically illustrate a partial structure of the lens carrier 50 of the present application. As shown in Figures 31 and 32, a circuit board 60b is disposed on the base 60 of the present application. The circuit board 60b is located within the first receiving portion 60a. The lens carrier 50 also includes a second flexible circuit board 270. The second flexible circuit board 270 connects the first flexible circuit board 160 to the circuit board 60b disposed on the base 60, enabling signal exchange between the first flexible circuit board 160 on the swing support 90 and the circuit board 60b on the base 60. For example, the first flexible circuit board 160 on the swing support 90, the second flexible circuit board 270, and the circuit board 60b on the base 60 can control the second driver 101, the first sub-driver 121, and the second sub-driver 123 on the first flexible circuit board 160.

[0274] Figure 33 schematically illustrates the structure of the second flexible printed circuit board 270 of the present application. As shown in Figure 33 , the second flexible printed circuit board 270 includes a first connection end 270a and a second connection end 270b. The first connection end 270a is electrically connected to the first flexible printed circuit board 160, while the second connection end 270b is electrically connected to the printed circuit board 60b.

[0275] When adjusting the position of the lens, the rotating support 70 can drive the swing support 90 to rotate about the first axis P1, or the swing support 90 can rotate relative to the rotating support 70 about the second axis P2. When the swing support 90 moves, it applies a rotational torque to the second flexible circuit board 270. Because the second flexible circuit board 270 is deformable, it can deform accordingly under the influence of the swing support 90. This reduces the possibility of the second flexible circuit board 270 applying a reverse rotational torque on the swing support 90, which would result in significant rotational resistance, ensuring a faster and more timely rotational response. Furthermore, by distributing the torque through deformation, the second flexible circuit board 270 can reduce the possibility of the second flexible circuit board 270 itself breaking due to the large rotational torque.

[0276] In some embodiments, the first flexible printed circuit board 160 includes a main body 161. The main body 161 is located on the side of the swing support 90 facing the base 60. The circuit board 60b on the base 60 is disposed facing the main body 161. For example, along the third axis P3, a distance exists between the swing support 90 and the first base plate 62 of the base 60. The main body 161 is located on the side of the swing support 90 facing the first base plate 62. The circuit board 60b is disposed on the first base plate 62. The first connecting end 270a is electrically connected to the main body 161. The second flexible printed circuit board 270 can be disposed between the swing support 90 and the first base plate 62 of the base 60. When the swing support 90 rotates, the swing support 90 and the first flexible printed circuit board rotate synchronously, thereby causing the main body 161 to drive the first connecting end 270a to rotate synchronously, thereby applying a torque to the second flexible printed circuit board 270.

[0277] In some examples, the base 60 includes a first bottom plate 62. The swing support 90 includes a second bottom plate 93. The first bottom plate 62 of the base 60 is disposed facing the second bottom plate 93 of the swing support 90. The circuit board 60b is disposed on the first bottom plate 62 of the base 60. The main body 161 of the first flexible printed circuit board 160 is disposed on the second bottom plate 93. The second flexible printed circuit board 270 can be disposed between the first bottom plate 62 and the second bottom plate 93.

[0278] In some implementations, the first connection end 270a is located in the middle region of the main body 161 along the first axis P1. When the swing support 90 rotates about the second axis P2, the amplitude of rotation decreases as the area of ​​the main body 161 closer to the middle region of the second axis P2 along the first axis P1. Therefore, the connection between the second flexible printed circuit board 270 and the middle region of the main body 161 results in a relatively small rotational torque exerted by the swing support 90 on the second flexible printed circuit board 270, thereby minimizing deformation of the second flexible printed circuit board 270 and reducing the possibility of breakage of the second flexible printed circuit board 270 due to significant deformation.

[0279] In some implementations, the first connection end 270a is located in the middle region of the main body 161 along the second axis P2. When the swing support 90 rotates about the first axis P1, the amplitude of rotation decreases along the second axis P2, as the area of ​​the main body 161 closer to the middle region of the first axis P1. Therefore, the connection between the second flexible printed circuit board 270 and the middle region of the main body 161 results in a relatively small rotational torque exerted by the swing support 90 on the second flexible printed circuit board 270, thereby minimizing deformation of the second flexible printed circuit board 270 and reducing the possibility of breakage of the second flexible printed circuit board 270 due to significant deformation.

[0280] In some feasible embodiments, as shown in FIG33 , along the first axis P1, the first connection end 270a is located in the middle area of ​​the main body 161, and along the second axis P2, the first connection end 270a is located in the middle area of ​​the main body 161, so that the connection position between the second flexible circuit board 270 and the main body 161 can be relatively close to the intersection of the first axis P1 and the second axis P2, which is beneficial to further reduce the rotational torque of the swing support 90 acting on the second flexible circuit board 270, so that the deformation of the second flexible circuit board 270 is relatively small.

[0281] In some implementations, FIG34 schematically illustrates a partial structure of the lens carrier 50 of the present application. As shown in FIG34 , along the first axis P1, a distance exists between the first connecting end 270a and the second connecting end 270b. Along the first axis P1, the first connecting end 270a is connected to an edge region of the main body 161 away from the second connecting end 270b. Along the first axis P1, the first connecting end 270a and the second connecting end 270b are located on either side of the actuator 1522. Since the distance between the first connection end 270a and the second connection end 270b is relatively large, the length of the second flexible circuit board 270 can be relatively increased in a narrow space, so that the swing support 90 applies a rotational torque to the second flexible circuit board 270, so that when the second flexible circuit board 270 is deformed, the second flexible circuit board 270 as a whole can effectively disperse the rotational torque, thereby reducing the torque borne by the first connection end 270a and the second connection end 270b, ensuring that the connection state of the first connection end 270a and the second connection end 270b is stable and reliable and not prone to falling off.

[0282] In some embodiments, the second flexible circuit board 270 includes a first transition section 271, an intermediate transition section 272, and a second transition section 273. The first transition section 271 and the second transition section 273 are located on the same side of the intermediate transition section 272. The end of the first transition section 271 distal to the intermediate transition section 272 forms a first connection end 270a. The end of the second transition section 273 distal to the intermediate transition section 272 forms a second connection end 270b. The intermediate transition section 272 is in a free state, that is, it is not connected to the base 60 or the swing support 90. Therefore, when the swing support 90 applies a rotational torque to the second flexible circuit board 270, the intermediate transition section 272 is easily deformed.

[0283] In some examples, the first transition section 271 includes an inclined portion. The inclined portion is tilted toward the swing support 90. The first connecting end 270a is located in a region of the inclined portion near the swing support 90. The region of the inclined portion away from the swing support 90 is connected to the intermediate transition section 272. The intermediate transition section 272 is relatively far from the first connecting end 270a. When the swing support 90 rotates, and the swing support 90 drives the first connecting end 270a to move synchronously, the inclined portion deforms to disperse the rotational torque, thereby reducing the deformation of the intermediate transition section 272 and the second transition section 273.

[0284] For example, the intermediate transition section 272 and the second transition section 273 can be flat. Along the third axis P3, the inclined portion is located on the side of the intermediate transition section 272 and the second transition section 273 facing away from the first bottom plate 62 of the base 60. The intermediate transition section 272 and the second transition section 273 are arranged near the first bottom plate 62 of the base 60.

[0285] In some examples, the second transition section 273 includes a narrowing portion 2731. Along the first axis P1, the width of the narrowing portion 2731 is smaller than the width of the first connection end 270a. The narrowing portion 2731 connects the second connection end 270b and the intermediate transition section 272. The second connection end 270b has a larger width, thereby providing a larger connection area with the circuit board 60b on the base 60, ensuring a stable and reliable connection. The narrowing portion 2731 has a smaller angle, making it relatively easy for the second transition section 273 to deform at the narrowing portion 2731, effectively dispersing the rotational torque.

[0286] In some examples, along the first axis P1, the width of the first connection end 270a is smaller than the width of the second connection end 270b. For example, on the second flexible circuit board 270, the width of the second connection end 270b is the largest. The width of the first transition section 271 can be greater or less than the width of the intermediate transition section 272. The width of the intermediate transition section 272 refers to the dimension along the second axis P2.

[0287] In some examples, along the first axis P1, the two ends of the intermediate transition section 272 are respectively connected to the first transition section 271 and the second transition section 273, so that the distance between the first transition section 271 and the second transition section 273 is maximized, which is beneficial to extending the deformable path from the first connection end 270a to the second connection end 270b, and is beneficial to dispersing the rotational torque and reducing the rotational torque borne at the second connection end 270b.
