Description

Camera module and electronic device

[0001] The present application claims priority to the Chinese patent application No. 202410545085.5, filed on April 30, 2024, and entitled "Camera module and electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of electronic devices, in particular to a camera module and an electronic device. BACKGROUND

[0003] When a camera device with camera function, such as a mobile phone, a tablet computer, etc., takes a picture, the picture may be blurred, ghosted or out of focus due to slight shaking. With the continuous maturation and expansion of the camera device market, the demand for high performance of camera devices is increasing, which puts higher requirements on the automatic focusing (AF) function and optical image stabilization (OIS) function of camera devices. The anti-shake function of the camera device in the prior art needs to be improved. SUMMARY

[0004] Embodiments of the present application provide a camera module and an electronic device, which aims to improve the anti-shake performance of the camera module.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions.

[0006] In a first aspect, the present application provides a camera module. The camera module comprises a lens holder, a first frame, a first rotating shaft and a first driving assembly. The lens holder is used to accommodate a lens module. The first frame is sleeved outside the lens holder; the first rotating shaft and the first driving assembly, the first driving assembly comprising a first arm and a swing piece, the first frame being rotationally connected with the swing piece through the first rotating shaft, and the swing piece being connected with the lens holder; when the camera module is in a first state, the first frame rotates along a first reference direction about a first virtual axis, and the first arm drives the swing piece to rotate along a first direction about an axis of the first rotating shaft; the first reference direction is opposite to the first direction, and the first virtual axis is parallel to the axis of the first rotating shaft. The swing piece is connected with the lens holder, so that the swing piece moves synchronously with the lens holder. When the camera module is in the first state, the rotating directions of the lens holder and the first frame are opposite. If a component (such as a mobile phone middle frame) connected with the first frame shakes, the first arm drives the mobile phone middle frame to rotate relative to the lens holder to weaken the offset of the lens holder caused by the rotation of the first frame. The influence of the shaking of the first frame on the lens module is weakened, the influence of the rotation of the first frame on the shooting effect is weakened, and the anti-shake performance of the lens module is improved.

[0007] With reference to the first aspect, in some possible implementation, the first arm includes a first end and a second end opposite to each other, and the first end is connected with the first frame. The first arm drives the swing member to rotate about the axis of the first rotating shaft in the first direction includes that the second end drives the swing member to rotate about the axis of the first rotating shaft in the first direction.

[0008] With reference to the first aspect, in some possible implementation, the first driving assembly further includes a second arm. When the camera module is in the second state, the first frame rotates about the first virtual axis in the second reference direction, and the second arm drives the swing member to rotate about the axis of the first rotating shaft in a second direction opposite to the first direction; and the first reference direction is opposite to the second reference direction. In this way, if the component connected with the first frame shakes, the second arm drives the mobile phone frame to rotate relative to the lens holder to weaken the deviation of the lens holder caused by the rotation of the first frame. The anti-shake performance of the lens module is improved.

[0009] With reference to the first aspect, in some possible implementation, the first driving assembly further includes a traction member, and the first arm and the second arm are connected through the traction member. The swing member has a first abutting portion and a second abutting portion on opposite sides. When the camera module is in the first state, the first arm abuts against the first abutting portion; and the second arm and the second abutting portion have a first gap therebetween. When the camera module is in the second state, the second arm abuts against the second abutting portion; and the first arm and the first abutting portion have a second gap therebetween. In this way, in the first state, the force of the second arm can be transmitted to the first arm through the traction member, and then transmitted to the swing member. The first arm can drive the swing member to rotate through the first abutting portion. The first gap prevents the second arm from interfering with the movement of the swing member towards the second arm. In this way, the first arm and the second arm can jointly drive the swing member to rotate about the axis of the first rotating shaft, so that the swing member can rotate through a larger angle. In the second state, the force of the first arm can be transmitted to the second arm through the traction member, and then transmitted to the swing member. The second arm can drive the swing member to rotate through the second abutting portion. The second gap prevents the first arm from interfering with the movement of the swing member towards the first arm. In this way, the first arm and the second arm can jointly drive the swing member to rotate about the axis of the first rotating shaft, so that the swing member can rotate through a larger angle.

[0010] In some possible implementation modes of the first aspect, the traction member comprises a first elastic member; one end of the first elastic member is connected to the first arm, and the other end of the first elastic member is connected to the second arm. When the first elastic member is in a free state, the first arm and the first abutting portion are in abutment, and the second arm and the second abutting portion are in abutment. In this way, when the first elastic member is subjected to an external force, the first elastic member with elasticity will be deformed. The deformation adjusts the distance between the first arm of the first arm and the first arm of the second arm. When the swing member needs to rotate, the first arm or the second arm exerts a force on the first elastic member to make the second arm and the second abutting portion have a first gap, or to make the first arm and the first abutting portion have a second gap. The first elastic member can adjust the size of the second gap or the first gap.

[0011] In some possible implementation modes of the first aspect, the traction member further comprises a second elastic member; one end of the second elastic member is connected to the first arm, and the other end of the second elastic member is connected to the second arm; the first elastic member and the second elastic member are respectively located on opposite sides of the first arm. When the second elastic member is in a free state, the first arm and the first abutting portion are in abutment, and the second arm and the second abutting portion are in abutment. The first elastic member and the second elastic member can make the force between the first arm and the second arm more evenly distributed. There are at least two force points between the first arm and the second arm, which avoids the force between the first arm and the second arm from being concentrated and deviated.

[0012] In some possible implementation modes of the first aspect, the first driving assembly further comprises a driving member; one end of the driving member is connected to the swing member, and the other end of the driving member is connected to the first arm. In this way, the force of the first arm can be transmitted to the swing member through the driving member, so that the swing member rotates around the axis of the first rotating shaft.

[0013] In some possible implementation modes of the first aspect, the first driving assembly further comprises a first magnetic member and a second magnetic member; the first magnetic member is connected to the first arm, and the second magnetic member is connected to the swing member; the first magnetic member and the second magnetic member are magnetically attracted to each other. In this way, when the first arm connected to the first magnetic member moves, the second magnetic member moves close to the first magnetic member under the interaction force of the first magnetic member and the second magnetic member, so that the swing member connected to the second magnetic member rotates around the axis of the first rotating shaft.

The elastic layer can deform, and the space generated by the deformation provides a bending space for the bending process of the first deformation layer and the second deformation layer, so that the first deformation layer and the second deformation layer are prevented from being torn or damaged due to the inability to release internal stress during the bending process. During the bending process of the first deformation layer and the second deformation layer, the arm body connected with the elastic layer also bends to generate a force for driving the swing piece to rotate about the axis of the first rotating shaft.

The third reference direction and the fourth reference direction are opposite to each other, and the fourth direction and the third direction are opposite to each other.

[0019] With reference to the first aspect, in some possible implementation manners, the first driving assembly further includes a traction member, and the third arm and the fourth arm are connected through the traction member.

In the embodiments of the present application, the electronic device can be a foldable device or an un-folding device.

[0059] For the convenience of description, the electronic device is taken as a mobile phone in the following description. FIG. 1 is a structural schematic diagram of an electronic device 01. As shown in FIG. 1, the electronic device 01 includes a cover plate 11, a display screen 12, a middle frame 13, and a rear shell 15. The rear shell 15 is also referred to as a rear cover. The rear shell 15 and the display screen 12 are respectively located on two sides of the middle frame 13, and the middle frame 13 and the display screen 12 are arranged in the rear shell 15. The cover plate 11 is arranged on a side of the display screen 12 away from the middle frame 13, and a display surface of the display screen 12 faces the cover plate 11.

[0060] In some embodiments of the present application, the display screen 12 is a multi-layer structure. The display screen 12 includes, for example, a touch panel (TP) module, a liquid crystal display (LCD) module, and a back light unit (BLU). Alternatively, in some other embodiments of the present application, the display screen 12 can be an organic light emitting diode (OLED) display screen. In some other embodiments of the present application, the display screen 12 can be an active matrix organic light emitting diode (AMOLED) display screen.

[0061] For the convenience of description, the thickness direction of the display screen 12 is defined as the z direction, in other words, the rear shell 15 and the display screen 12 are arranged in a stack along the z direction. It can be understood that, in the embodiments in which the display screen 12 is a curved screen, the display screen 12 is perpendicular to the z direction in the planar part.

[0062] It can be understood that the contour shape of the cover plate 11 can match the contour shape of the display screen 12. For example, the outer contour of the cover plate 11 is square. The cover plate 11 can be a cover glass, and can also be replaced by a cover plate made of other materials, such as a cover plate made of ultra-thin glass material, a cover plate made of polyethylene terephthalate (PET) material, and the like.

[0063] In some embodiments, a user can interact with the electronic device 01 through the cover plate 11 or the display screen. Illustratively, the cover plate 11 or the display screen can receive an input operation of the user, and make a corresponding output in response to the input operation, for example, the user can select (or otherwise) open, edit a graphic, etc. by touching or pressing a graphic position on the display screen.

[0064] Illustratively, the electronic device 01 further includes a printed circuit board 16. The printed circuit board 16 can be disposed between the back shell 15 and the display screen 12. The printed circuit board 16 can be made of a flame-retardant material (FR-4) medium plate, a Rogers medium plate, a hybrid medium plate of Rogers and FR-4, etc. Here, FR-4 is a code of a flame-retardant material grade, and the Rogers medium plate is a high-frequency plate. The printed circuit board 16 carries electronic components, such as a radio frequency chip, etc.

[0065] In some embodiments, the electronic device 01 also has an image acquisition function. As shown in FIG. 1, the electronic device 01 further includes a camera module 20. The camera module 20 is used to acquire images. The camera module 20 is connected with the middle frame 13 or the back shell 15.

[0066] In some embodiments, the camera module 20 can be regarded as a front camera, that is, the object side of the camera module 20 is located at the light-emitting side of the display screen 12. In some embodiments, the camera module 20 can be regarded as a rear camera, that is, the object side of the camera module 20 is located at the light-receiving side of the display screen 12. The embodiments of the present application take the camera module 20 as a rear camera as an example for description.

[0067] The anti-shake function of the camera assembly in the prior art needs to be improved. The camera assembly provided by the embodiments of the present application can effectively improve the anti-shake performance of the camera assembly.

[0068] FIG. 2a is a structural schematic diagram of the camera module 20 provided by the embodiments of the present application. FIG. 2b is a structural schematic diagram of the camera module 20 shown in FIG. 2a from another perspective. Please refer to FIG. 2a and FIG. 2b. The camera module 20 includes a first frame body 110, a first rotating shaft 210 (as shown in FIG. 3a), a first driving assembly 310, and a lens holder 220. The first frame body 110 is sleeved outside the lens holder 220, and the first frame body 110 is rotationally connected with the lens holder 220 through the first rotating shaft 210. The first driving assembly 310 is used to drive the lens holder 220 to rotate relative to the first frame body 110 along a first direction or along a second direction.

[0069] As shown in FIG. 2a, the axis of the first rotating shaft 210 is L1. Under the action of the first driving assembly 310, the lens holder 220 can rotate along the first direction or along the second direction around the axis L1.

[0070] In the embodiments of the present application, for the convenience of description, the extending direction of the axis L1 is defined as the x direction. The x direction and the z direction are perpendicular to each other. It can be understood that the x direction and the z direction being perpendicular is not limited to the included angle between the x direction and the z direction being 90°, and the existence of assembly error or manufacturing error can be allowed. Exemplarily, the included angle between the x direction and the z direction can be 85°-95°. For example, it can be 85°, 87°, 88°, 89°, 90°, 91°, 92°, 93° or 95°, and the like. The rest of the description about perpendicular in the present document is the same.

[0071] In the case of the same or parallel axis, the direction of rotation includes two opposite directions. For example, the first direction and the second direction are opposite; if the first direction is the clockwise direction, the second direction is the counterclockwise direction. Conversely, if the second direction is the clockwise direction, the first direction is the counterclockwise direction. The present application takes the first direction as the clockwise direction and the second direction as the counterclockwise direction as an example. In the subsequent figures, the rotation of the swing member in the positive direction also represents the rotation in the first direction, and the rotation of the swing member in the reverse direction also represents the rotation of the swing member in the second direction.

[0072] FIG. 3a is an exploded structural schematic diagram of the camera module 20 shown in FIG. 2a. Referring to FIG. 3a, the first driving assembly 310 includes a first arm 311 and a swing member 313. The swing member 313 is sleeved on the first rotating shaft 210, and the first frame 110 is rotationally connected with the swing member 313 through the first rotating shaft 210. The swing member 313 is connected with the lens holder 220.

[0073] Exemplarily, when the camera module 20 is in the first state, the first frame 110 rotates around a first virtual axis (as shown in FIG. 3b) in a first reference direction (as shown in FIG. 3b), and the first arm 311 drives the swing member 313 to rotate around the axis L1 of the first rotating shaft 210 in the first direction. The first virtual axis is parallel to the axis L1 of the first rotating shaft 210.

[0074] The embodiments of the present application do not limit the connection mode of the first arm 311 and the first frame 110. In some embodiments, the first arm 311 and the first frame 110 can be independently provided. The movement of the first frame 110 has little effect on the first arm 311. In some embodiments, the first arm 311 has two ends arranged oppositely, which are a first end 301 and a second end 302 (as shown in FIG. 4). The first end 301 is connected with the first frame 110. The first arm 311 driving the swing member 313 to rotate around the axis L1 of the first rotating shaft 210 in the first direction includes: the second end 302 driving the swing member 313 to rotate around the axis L1 of the first rotating shaft 210 in the first direction. In this way, it is not necessary to additionally provide a structure to support the first arm 311. The integration of the camera module 20 can be increased, and the volume of the camera module 20 can be reduced.

[0075] Because the swing member 313 is connected with the lens holder 220, when the first frame body 110 rotates around the first virtual axis along the first reference direction, the first arm 311 drives the swing member 313 to rotate around the axis L1 of the first rotating shaft 210 along the first direction. The first arm 311 weakens the deviation of the lens holder 220 caused by the rotation of the first frame body 110, and accordingly weakens the deviation of the lens module. The deviation of the lens module from the shooting object is avoided, the anti-shake performance of the lens module is improved, and the quality of the picture captured by the camera module 20 is improved.

[0076] When the camera module 20 is in the second state, the first frame body 110 rotates around the first virtual axis along the second reference direction (as shown in FIG. 3b), and the first driving assembly 310 drives the swing member 313 to rotate around the axis L1 of the first rotating shaft 210 along the second direction. The second direction is opposite to the first direction, and the first reference direction is opposite to the second reference direction.

[0077] In the embodiments of the present application, the swing member 313 moves synchronously with the lens holder 220, so the angle of swing or rotation of the swing member 313 is the same as the angle of swing or rotation of the lens holder 220.

[0078] The connection mode of the swing member 313 and the lens holder 220 is not limited in the embodiments of the present application. For example, the swing member 313 and the lens holder 220 are bonded, clamped or welded, etc. Alternatively, the swing member 313 and the lens holder 220 can be connected as an integral molded part.

[0079] For example, in some embodiments of the present application, after the component (such as a mobile phone middle frame) connected with the first frame body 110 shakes, the camera module 20 is in the first state or in the second state.

[0080] FIG. 3b is a motion schematic diagram of the first frame body 110 and the lens holder 220 in the first state. In FIG. 3b, in the first state, the first frame body 110 tilts or shakes, so that the back side of the first frame body 110 is higher than the front side. The tilt of the first frame body 110 can be regarded as that the first frame body 110 rotates around the first virtual axis along the second reference direction. Correspondingly, the lens holder 220 also has a tendency to rotate synchronously with the first frame body 110. In this state, the second end 302 (as shown in FIG. 3a) drives the swing member 313 (as shown in FIG. 3a) to rotate around the axis L1 of the first rotating shaft 210 along the first direction (the positive direction in FIG. 3b), which can compensate for the deviation of the lens holder 220 caused by the rotation of the first frame body 110 around the first virtual axis along the second reference direction, and achieve the purpose of anti-shake.

[0081] Fig. 3c is a schematic diagram of the movement of the first frame 110 and the frame 220 in the second state. In Fig. 3c, in the second state, the first frame 110 is tilted or shaken, so that the front side of the first frame 110 is higher than the back side. The tilt of the first frame 110 can be regarded as a rotation of the first frame 110 about the first virtual axis in the second reference direction. Accordingly, the frame 220 also has a tendency to rotate synchronously with the first frame 110. In this state, the second end 302 (as shown in Fig. 3a) drives the swing member 313 (as shown in Fig. 3a) to rotate about the axis L1 of the first rotation shaft 210 in the second direction (the reverse direction in Fig. 3b), which can compensate for the rotation of the first frame 110 about the first virtual axis in the second reference direction, so as to achieve the purpose of anti-shake.

[0082] Please refer to Fig. 3a. In some embodiments of the present application, the camera module 20 can further include a lens module 201, which is located in the frame 220 and connected with the frame 220. The lens module 201 and the frame 220 move synchronously. The axis of the optical axis of the lens module 201 is parallel to the thickness direction (z direction) of the display screen 12. It can be understood that, since the lens module 201 has an anti-shake function, when the electronic device is shaken, the optical axis of the lens module 201 will be offset to compensate for the shaking, for example, the optical axis of the lens module 201 is offset to have a small included angle with the z direction. The embodiments of the present application are described by taking the axis of the optical axis of the lens module 201 being parallel to the z direction when the electronic device is not shaken as an example.

[0083] For example, the lens module 201 includes a lens and an image sensor. In some embodiments, the lens module 201 can further include a variable aperture module, an automatic focusing module, an optical anti-shake module, etc.

[0084] In some embodiments of the present application, the first frame 110 is connected with the middle frame 13 (as shown in Fig. 1). For example, the first frame 110 and the middle frame 13 can be connected by a glue layer, a solder layer or other connecting structures. In some embodiments of the present application, the first frame 110 is connected with the back shell 15 (as shown in Fig. 1). For example, the first frame 110 and the back shell 15 can be connected by a glue layer, a solder layer or other connecting structures. When the user uses the mobile phone, the first frame 110, the middle frame 13 and the back shell 15 move synchronously, for example, in the process of the first frame 110 being tilted about the x direction in the reverse direction, the first frame 110 and the middle frame 13 are also tilted about the x direction in the reverse direction.

[0085] The embodiments of the present application do not limit the shape of the first frame 110. For example, the first frame 110 can be a ring structure, which can be an open ring structure or a closed ring structure. The ring structure can be a circular ring, an elliptical ring, a polygonal ring or a special-shaped ring structure, etc.

[0086] In embodiments of the present application, the swing member 313 has multiple implementations for rotating around the axis L1 of the first rotating shaft 210. In some embodiments, the first rotating shaft 210 and the first frame body 110 are fixedly connected, and the first rotating shaft 210 and the swing member 313 are rotatably connected. The fixed connection between the first rotating shaft 210 and the first frame body 110 includes but is not limited to interference fit, bonding, clamping, welding, or the like, and the first rotating shaft 210 and the first frame body 110 can also be connected as an integral molded part. The rotatable connection between the first rotating shaft 210 and the swing member 313 includes but is not limited to bearing, universal joint, or hinge, or the like.

[0087] In some embodiments, the first rotating shaft 210 and the first frame body 110 are rotatably connected, and the first rotating shaft 210 and the swing member 313 are fixedly connected. The fixed connection between the first rotating shaft 210 and the swing member 313 includes but is not limited to interference fit, bonding, clamping, welding, or the like, and the first rotating shaft 210 and the swing member 313 can also be connected as an integral molded part. The rotatable connection between the first rotating shaft 210 and the first frame body 110 includes but is not limited to bearing, universal joint, or hinge, or the like.

[0088] In some embodiments of the present application, the first driving assembly 310 can further include a second arm 312. The second arm 312 has a third end 303 and a fourth end 304 arranged opposite to each other. The third end 303 is connected to the first frame body 110. The fourth end 304 cooperates with the swing member 313. The power of the third end 303 can be transmitted to the swing member 313 through the fourth end 304.

[0089] When the camera module 20 is in the first state, the fourth end 304 drives the swing member 313 to rotate around the axis L1 of the first rotating shaft 210 in the first direction. When the camera module 20 is in the second state, the fourth end 304 drives the swing member 313 to rotate around the axis L1 of the first rotating shaft 210 in the second direction.

[0090] In this way, the second end 302 and the fourth end 304 drive the swing member 313 to rotate in the same direction, which can improve the angle of rotation of the swing member 313.

[0091] In embodiments of the present application, the connection relationship between the second end 302 and the swing member 313 has multiple forms, and correspondingly, the connection relationship between the fourth end 304 and the swing member 313 also has multiple forms. The following is an exemplary description.

[0092] Figure 4 is a structural schematic diagram of a first driving assembly 310 according to an embodiment of the present application. Referring to Figure 4, the first driving assembly 310 further comprises a traction member 314, the second arm 312 and the first arm 311 are connected through the traction member 314. Exemplarily, one end of the second arm 312 is connected with the traction member 314, and the other end of the first arm 311 is connected with the traction member 314.

[0093] The swing member 313 has a first abutting portion 3131 and a second abutting portion 3132, which are located at opposite sides of the swing member 313. The second end 302 is used to abut against the first abutting portion 3131, and the fourth end 304 is used to abut against the second abutting portion 3132.

[0094] Figure 5a is a structural schematic diagram of the swing member 313, the second end 302 and the fourth end 304 in a first state according to an embodiment of the present application. Referring to Figure 5a, in the first state, the second end 302 abuts against the first abutting portion 3131, and the fourth end 304 has a first gap 001 with the second abutting portion 3132. Because the second arm 312 and the first arm 311 are connected through the traction member 314, the force of the second arm 312 can be transmitted to the second end 302 of the first arm 311 through the traction member 314 and then to the swing member 313. The second end 302 can drive the swing member 313 to rotate in a first direction (the positive direction in Figure 5a) through the first abutting portion 3131. The existence of the first gap 001 makes the fourth end 304 not interfere with the movement of the swing member 313 towards the fourth end 304. In this way, the second end 302 and the fourth end 304 can jointly drive the swing member 313 to rotate in the first direction about the axis L1 of the first rotation shaft 210, so that the swing member 313 can rotate at a larger angle.

[0095] In Figure 5a, the second arm 312 (as shown in Figure 4) moves away from the swing member 313, the third end 303 (as shown in Figure 4) applies a force F21 to the fourth end 304, and the force F21 is transmitted to the second end 302 through the traction member 314. The first arm 311 (as shown in Figure 4) moves close to the swing member 313, and the first end 301 (as shown in Figure 4) applies a force F11 to the second end 302. In this way, the force F21 and the force F11 are both transmitted to the swing member 313 through the first abutting portion 3131, so that the swing member 313 rotates in the first direction (the positive direction in Figure 5a). The directions of the force F21 and the force F11 are the same.

[0096] It can be understood that as the swing member 313 rotates forward, the position and size of the aforementioned first gap 001 can change. For example, during the rotation of the swing member 313 in the first direction (forward direction in FIG. 5a), the width s1 of the first gap 001 can gradually decrease until s1 equals 0, i.e., the fourth end 304 abuts against the second abutting portion 3132. In some scenarios, the swing member 313 can stop rotating before the width s1 of the first gap 001 decreases to 0. For example, according to a requirement (which can be an instruction issued by the printed circuit board to the camera module), the second arm 312 and the first arm 311 apply a torque to the swing member 313, which causes the swing member 313 to rotate by a preset angle, and the swing member 313 stops after rotating by the preset angle, and the width s1 of the first gap 001 is greater than 0 after the swing member 313 stops.

[0097] FIG. 5b is a structural schematic view of the swing member 313, the second end 302, and the fourth end 304 in a second state according to an embodiment of the present application. Referring to FIG. 5b, in the second state, the fourth end 304 abuts against the second abutting portion 3132, and the second end 302 and the first abutting portion 3131 have a second gap 002 therebetween. As described above, because the second arm 312 and the first arm 311 are connected through the traction member 314, the force of the first arm 311 can be transmitted to the fourth end 304 of the second arm 312 through the traction member 314 and then to the swing member 313. The fourth end 304 can drive the swing member 313 to rotate reversely through the second abutting portion 3132. The existence of the second gap 002 prevents the second end 302 from interfering with the movement of the swing member 313 toward the second end 302. In this way, the second end 302 and the fourth end 304 can jointly drive the swing member 313 to rotate reversely about the axis L1 of the first rotation shaft 210, so that the swing member 313 can rotate by a larger angle.

[0098] Similarly, as the swing member 313 rotates reversely, the position and size of the aforementioned second gap 002 can change. During the rotation of the swing member 313 in the second direction (reverse direction in FIG. 5b), the width s2 of the second gap 002 can gradually decrease until s2 equals 0, i.e., the second end 302 abuts against the first abutting portion 3131. Similarly, in some scenarios, the swing member 313 can stop rotating before the width s2 of the second gap 002 decreases to 0. For example, the second arm 312 and the first arm 311 apply a torque to the swing member 313, which causes the swing member 313 to rotate by a preset angle, and the swing member 313 stops after rotating by the preset angle, and the width s2 of the second gap 002 is greater than 0 after the swing member 313 stops.

[0099] In FIG. 5b, the first arm 311 (as shown in FIG. 4) moves away from the swing piece 313, the first end 301 (as shown in FIG. 4) applies a force F12 to the second end 302, and the force F12 is transmitted to the fourth end 304 through the traction piece 314. The second arm 312 (as shown in FIG. 4) moves close to the swing piece 313, and the third end 303 (as shown in FIG. 4) applies a force F22 to the fourth end 304. In this way, the force F12 and the force F22 are both transmitted to the swing piece 313 through the second contact portion 3132, so that the swing piece 313 rotates in the second direction (the reverse direction in FIG. 5b). The directions of the force F12 and the force F22 are the same.

[0100] The shape of the swing piece 313 is not limited in the embodiments of the present application. For example, the swing piece 313 is eccentric in shape. The swing piece 313 is coaxially arranged with the first rotating shaft 210. The distance from the outer periphery of the swing piece 313 to the axis of the first rotating shaft 210 is not completely the same. The first contact portion 3131 is located in a region where the swing piece 313 is far away from the axis of the first rotating shaft 210, and the second contact portion 3132 is also located in a region where the swing piece 313 is far away from the axis of the first rotating shaft 210.

[0101] The way in which the first contact portion 3131 and the second end 302 abut is not limited in the embodiments of the present application. In some embodiments, the first contact portion 3131 and the second end 302 abut through a groove and a protrusion. The groove is arranged on the first contact portion 3131, and the protrusion is arranged on the second end 302; or the groove is arranged on the second end 302, and the protrusion is arranged on the first contact portion 3131. For example, the groove can be a V-shaped groove, and the protrusion can be a conical protrusion.

[0102] Similarly, the way in which the second contact portion 3132 and the fourth end 304 abut can refer to the description of the abutting way of the first contact portion 3131 and the second end 302.

[0103] In some embodiments of the present application, the swing piece 313 is an integrally formed member. The first contact portion 3131 and the second contact portion 3132 are also connected as an integrally formed member. In some embodiments, the swing piece 313 can be connected by a plurality of separate components, for example, the first contact portion 3131 and the second contact portion 3132 are separately arranged and connected to form the swing piece 313 by bonding or welding.

[0104] Please refer back to FIG. 4. In the embodiments of the present application, the first arm 311 and the second arm 312 are arranged around the outer periphery of the frame 220 (as shown in FIG. 3b), and the swing piece 313 is located between the first arm 311 and the second arm 312. In other words, the first arm 311 and the second arm 312 are respectively located on opposite sides of the swing piece 313 along the circumferential direction of the frame 220. The first contact portion 3131 and the second end 302 are respectively located on opposite sides of the swing piece 313 along the circumferential direction of the frame 220.

[0105] In some embodiments of the present application, the traction member 314 can further comprise a first elastic member 3141, one end of which is connected to the first arm 311. The other end of the first elastic member 3141 is connected to the second arm 312.

[0106] When the first elastic member 3141 is in a free state, the second end 302 and the first abutting portion 3131 abut, and the fourth end 304 and the second abutting portion 3132 abut. When the first elastic member 3141 is subjected to an external force, the first elastic member 3141 with elasticity will be deformed.

[0107] The aforementioned first elastic member 3141 is in a free state, which means that the interaction force between the second arm 312 and the first elastic member 3141 is small, for example, the size of the interaction force is less than or equal to 10 Newton (N), and the interaction force between the first arm 311 and the first elastic member 3141 is small, for example, the size of the interaction force is less than or equal to 10 Newton (N).

[0108] Please return to FIG. 5a, in the first state, the force F21 of the fourth end 304 is transmitted to the first elastic member 3141, so that the first elastic member 3141 is elongated, and the fourth end 304 moves away from the second abutting portion 3132, so that there is a first gap 001 between the fourth end 304 and the second abutting portion 3132. Part of the force F21 of the fourth end 304 makes the first elastic member 3141 be elongated, and the remaining part is transmitted to the second end 302 to drive the swing member 313 to rotate forward.

[0109] The setting of the first elastic member 3141 can adjust the size of the first gap 001. For example, if the force F21 is larger, the first gap 001 is correspondingly larger. As mentioned above, in the process of forward rotation of the swing member 313, the width s1 of the first gap 001 can gradually decrease until s1 is equal to 0, that is, the fourth end 304 abuts against the second abutting portion 3132. After the first gap 001 increases, the width s1 increases, and the swing member 313 can swing a larger amplitude to be abutted by the fourth end 304. In this way, the swing member 313 can swing a larger angle.

[0110] In addition, after the force F21 of the fourth end 304 and the force F11 of the second end 302 are removed, the elastic potential energy stored in the first elastic member 3141 makes the fourth end 304 move close to the second abutting portion 3132 to abut against the second abutting portion 3132.

[0111] Similarly, in FIG. 5b, in the second state, the force F12 of the second end 302 is transmitted to the first elastic member 3141, so that the first elastic member 3141 is elongated, the second end 302 moves away from the first abutting part 3131, and the second gap 002 exists between the second end 302 and the first abutting part 3131. Part of the force F12 of the second end 302 elongates the first elastic member 3141, and the remaining part is transmitted to the fourth end 304 to drive the swing member 313 to rotate reversely.

[0112] Similarly, the first elastic member 3141 can adjust the size of the second gap 002. The angle of the swing member 313 can be adjusted by adjusting the size of the force F12. When the force F12 and the force F22 are removed, the elastic potential energy stored in the first elastic member 3141 drives the second end 302 to move close to the first abutting part 3131, so that the second end 302 abuts against the first abutting part 3131.

[0113] In some embodiments, when the first elastic member 3141 is in a free state, the second end 302 abuts against the first abutting part 3131, and the fourth end 304 does not abut against the second abutting part 3132. Alternatively, when the first elastic member 3141 is in a free state, the second end 302 does not abut against the first abutting part 3131, and the fourth end 304 abuts against the second abutting part 3132. In this way, the first elastic member 3141 can also adjust the distance between the second end 302 and the fourth end 304, so that the swing angle of the swing member 313 is not limited by the distance between the second end 302 and the fourth end 304.

[0114] The embodiments of the present application do not limit the structure of the first elastic member 3141. For example, the first elastic member 3141 can be a spring or a spring.

[0115] The embodiments of the present application do not limit the connection mode of the first elastic member 3141 and the first arm 311. For example, the first elastic member 3141 and the first arm 311 can be connected by a glue layer, a welding layer or a clamping structure. Similarly, the first elastic member 3141 and the second arm 312 can be connected by a glue layer, a welding layer or a clamping structure.

[0116] Please refer to FIG. 4. In some embodiments of the present application, the traction member 314 can further include a second elastic member 3142. One end of the second elastic member 3142 is connected to the first arm 311. The other end of the second elastic member 3142 is connected to the second arm 312. The first elastic member 3141 and the second elastic member 3142 are respectively located on opposite sides of the first arm 311. For example, the first elastic member 3141 and the second elastic member 3142 are respectively located on both sides of the first arm 311 along the extension direction of the lens holder 220. In other words, the first elastic member 3141 and the second elastic member 3142 are respectively located on both sides of the first arm 311 along the z direction.

[0117] When the second elastic member 3142 is in a free state, the second end 302 and the first abutting portion 3131 abut, and the fourth end 304 and the second abutting portion 3132 abut. In this way, when the second elastic member 3142 is subjected to an external force, the second elastic member 3142 will deform. For example, when the second elastic member 3142 is in a free state, there is a gap between the swing member 313 and the second elastic member 3142, and the interference of the swing member 313 to the second elastic member 3142 is small during the deformation of the second elastic member 3142.

[0118] The first elastic member 3141 and the second elastic member 3142 can make the force between the first arm 311 and the second arm 312 more evenly distributed. There are at least two force points between the first arm 311 and the second arm 312, which avoids the force between the first arm 311 and the second arm 312 from being concentrated and deviated.

[0119] The structure of the second elastic member 3142, the relationship between the second elastic member 3142 and the second end 302, and the relationship between the second elastic member 3142 and the fourth end 304 can refer to the description of the first elastic member 3141 above, and will not be described here.

[0120] It can be understood that, in some embodiments of the present application, the traction member 314 can be a non-elastic structure. The traction member 314 can not include an elastic member.

[0121] FIG. 6 is a structural schematic diagram of another first driving assembly 310 provided by an embodiment of the present application. The difference between FIG. 6 and FIG. 4 is that the traction member 314 in FIG. 6 is a non-elastic member. It can be understood that the non-elastic member is different from the elastic member, and the deformation amount of the non-elastic member under the action of an external force is small, but it is not limited that the non-elastic member does not deform under the action of an external force.

[0122] In FIG. 6, the distance between the second end 302 and the fourth end 304 is greater than the distance between the first abutting portion 3131 and the second abutting portion 3132. The gap allows the swing member 313 to swing. The difference between the distance between the second end 302 and the fourth end 304 and the distance between the first abutting portion 3131 and the second abutting portion 3132 is related to the maximum angle by which the swing member 313 can swing.

[0123] In FIG. 6, the first gap 001 between the second abutting portion 3132 and the fourth end 304 has a width of s1. The third end 303 applies a force F21 to the fourth end 304, which is transmitted to the second end 302 by the traction member 314. The first end 301 applies a force F11 to the second end 302. Thus, the force F21 and the force F11 are both transmitted to the swing member 313 by the first abutting portion 3131, causing the swing member 313 to rotate in the forward direction. Since the traction member 314 is a non-elastic member, the distance between the second end 302 and the fourth end 304 does not change. The swing member 313 rotates in the forward direction until the second abutting portion 3132 abuts against the fourth end 304.

[0124] Similarly, when the swing member 313 rotates in the reverse direction, the force applied by the third end 303 and the first end 301 is transmitted to the second abutting portion 3132, causing the swing member 313 to rotate in the reverse direction until the second end 302 abuts against the first abutting portion 3131.

[0125] In the embodiment in which the traction member 314 is a non-elastic member, the traction member 314 and the first arm 311 can be connected by a glue layer, a welding layer, or a clamping structure, etc. The traction member 314 and the second arm 312 can also be connected by a glue layer, a welding layer, or a clamping structure, etc.

[0126] In some embodiments of the present application, the second end 302 can drive the swing member 313 to move in the first direction or the second direction by other means.

[0127] FIG. 7a is a structural schematic diagram of another first driving assembly 310 provided by an embodiment of the present application. Referring to FIG. 7a, in some embodiments, the first driving assembly 310 further includes a poking member 315, one end of the poking member 315 being connected to the swing member 313, and the other end of the poking member 315 being connected to the second end 302. Thus, the force applied by the second end 302 can be transmitted to the swing member 313 by the poking member 315, causing the swing member 313 to rotate in the first direction or the second direction about the axis L1 of the first rotation shaft 210.

[0128] As shown in FIG. 7a, the force F11 applied by the second end 302 can be transmitted to the swing member 313 by the poking member 315, causing the swing member 313 to perform a rotational movement.

[0129] The connection manner of the toggle 315 and the second end 302 is not limited in the embodiments of the present application. For example, the toggle 315 and the second end 302 can be connected by a glue layer, a welding layer or a clamping structure. In some embodiments, the toggle 315 and the second end 302 can be an integrally formed piece.

[0130] Similarly, the toggle 315 and the swing 313 can be connected by a glue layer, a welding layer or a clamping structure. In some embodiments, the toggle 315 and the swing 313 can be an integrally formed piece.

[0131] In some embodiments, the toggle 315 has a bending property. In the process of the swing 313 rotating, the toggle 315 bends. In this way, the second end 302 moving in a straight line can drive the swing 313 to rotate through the bendable toggle 315. For example, the second end 302 moves close to the swing 313. Because the toggle 315 is connected to the second end 302, the toggle 315 also moves in the direction of the second end 302 moving close to the swing 313. Because the toggle 315 has a bending property, the toggle 315 bends to generate a torque, which is transmitted to the swing 313 to make the swing 313 rotate.

[0132] For example, the material of the toggle 315 can include at least one of copper and its alloy, aluminum and its alloy, titanium and its alloy or nickel and its alloy. The toggle 315 can be a long strip structure such as a strip, a column or a wire.

[0133] In FIG. 7a, the swing 313 can be a ring structure. Because the toggle 315 is connected to the swing 313. The swing 313 can be a protrusion protruding on the first rotating shaft 210, and the second end 302 can drive the protrusion to rotate through the bendable toggle 315.

[0134] In FIG. 7a, the first driving assembly 310 includes the first arm 311. As described above, in some embodiments, the first driving assembly 310 can include a second arm.

[0135] FIG. 7b is a structural schematic diagram of another first driving assembly 310 including a second arm 312 provided by the embodiments of the present application. The difference between FIG. 7b and FIG. 7a is that in the example of FIG. 7b, the first driving assembly 310 can further include a second arm 312. One end of the toggle 315 is connected to the swing 313, and the other end of the toggle 315 away from the swing 313 is connected to the fourth end 304 of the second arm 312.

[0136] In FIG. 7b, the force F11 of the second end 302 and the force F21 of the fourth end 304 can be transmitted to the swing member 313 through the toggle member 315 to make the swing member 313 rotate. The force driving the swing member 313 to rotate is greater. In addition, the force driving the swing member 313 comes from the force F11 of the second end 302 and the force F21 of the fourth end 304, which can make the force on the toggle member 315 more uniform.

[0137] In FIG. 7b, the connection between the second arm 312 and the toggle member 315 can refer to the description of the connection between the first arm 311 and the toggle member 315 in the foregoing FIG. 7a, which will not be repeated here.

[0138] In the example of FIG. 7b, the first arm 311 and the second arm 312 are located on both sides of the swing member 313. The first arm 311 and the second arm 312 surround the outer periphery of the frame 220 (as shown in FIG. 3a), and the swing member 313 is located between the first arm 311 and the second arm 312. The space on the outer periphery of the frame 220 can be fully utilized, which is conducive to the miniaturization of the camera module.

[0139] In some embodiments of the present application, the first arm 311 and the second arm 312 can not be located on both sides of the swing member 313.

[0140] FIG. 7c is a structural schematic diagram of a first driving assembly 310 including a second arm 312 according to an embodiment of the present application. The difference between FIG. 7c and FIG. 7b is that in the example of FIG. 7c, the first arm 311 and the second arm 312 are located on the same side of the swing member 313. The first arm 311 and the second arm 312 can simultaneously drive the swing member 313 to rotate in the first direction or the second direction.

[0141] In the example of FIG. 7c, the first driving assembly 310 can also drive the swing member 313 to rotate. The space in the height direction (z direction) of the frame 220 (as shown in FIG. 3a) can be fully utilized.

[0142] FIG. 8 is a structural schematic diagram of a first driving assembly 310 according to an embodiment of the present application. Referring to FIG. 8, the first driving assembly 310 can include a first magnetic member 316 and a second magnetic member 317. The first magnetic member 316 is connected with the second end 302, and the second magnetic member 317 is connected with the swing member 313. The first magnetic member 316 and the second magnetic member 317 are magnetically attracted. In this way, after the second end 302 connected with the first magnetic member 316 moves, the second magnetic member 317 will move close to the first magnetic member 316 under the interaction force between the first magnetic member 316 and the second magnetic member 317, so as to make the swing member 313 connected with the second magnetic member 317 rotate in the first direction or the second direction around the axis L1 of the first rotation shaft 210.

[0143] In the embodiments of the present application, the first magnetic member 316 and the second end 302 can be connected by a glue layer, a welding layer or a clamping structure.

[0144] In the embodiments in which the first driving assembly 310 includes the second arm 312, the first driving assembly 310 can further include a third magnetic member 318. The third magnetic member 318 is connected to the fourth end 304. The third magnetic member 318 and the second magnetic member 317 are magnetically attracted to each other. Thus, after the fourth end 304 moves, the interaction force between the third magnetic member 318 and the second magnetic member 317 can cause the second magnetic member 317 to move closer to the third magnetic member 318, thereby driving the swing member 313 to rotate around the axis L1 of the first rotating shaft 210 in the first direction or the second direction.

[0145] Exemplarily, the third magnetic member 318 and the fourth end 304 can be connected by a glue layer, a welding layer or a clamping structure.

[0146] It can be understood that, in other embodiments, the second end 302 driving the swing member 313 to rotate in the first direction or the second direction is not limited to the above-described manner. Similarly, the fourth end 304 driving the swing member 313 to rotate in the first direction or the second direction is not limited to the above-described manner.

[0147] As described above, the first arm 311 moving away from or close to the swing member 313 drives the second end 302 to swing the swing member 313. The embodiments of the present application do not limit the implementation manner of the first arm 311 moving away from or close to the swing member 313. The following is exemplarily introduced.

[0148] FIG. 9 is a structural schematic view of the first arm 311 provided by the embodiments of the present application. Please refer to FIG. 9. The first arm 311 includes an arm body 410 and a deformation assembly 420. The deformation assembly 420 includes a first deformation layer 421, an elastic layer 423 and a second deformation layer 422 which are sequentially stacked in the a direction. The first deformation layer 421 or the second deformation layer 422 serves as the first end 301. One end of the arm body 410 is connected to the elastic layer 423, and the other end of the arm body 410 serves as the second end 302.

[0149] When the camera module is in the first state, the first deformation layer 421 and the second deformation layer 422 are both bent towards the a direction. When the camera module is in the second state, the first deformation layer 421 and the second deformation layer 422 are both bent towards the b direction.

[0150] The foregoing first arm driving the swing member to rotate in the first direction around the axis of the first rotating shaft includes: the first deformation layer and the second deformation layer being bent in the same direction, and the one end of the arm body away from the elastic layer driving the swing member to rotate in the first direction around the axis of the first rotating shaft.

[0151] The present embodiment does not limit the relationship between the extension direction of the axis L1 of the first rotating shaft 210 (i.e., the x direction in the foregoing) and the a direction. In FIG. 9, the a direction and the x direction are perpendicular to each other. It can be understood that, in the case where the first arm 311 provides driving for the swing member 313 to rotate in the first direction or the second direction, the bending direction a direction of the first deformation layer 421 and the second deformation layer 422 can be in any angle relationship with the x direction.

[0152] In FIG. 9, the bending direction b direction of the first deformation layer 421 is perpendicular to the axis L1 of the first rotating shaft 210. The extension direction of the arm body 410 is perpendicular to the b direction. The first arm 311 can be regarded as an L-shaped structure. The first arm 311 is arranged around the outer periphery of the frame 220 (as shown in FIG. 3a). The volume of the first arm 311 and the frame 220 can be reduced, which is beneficial to the miniaturization of the camera module.

[0153] In other embodiments, the first arm 311 can have other shapes, and the first arm 311 can have an arc-shaped structure arranged around the outer periphery of the frame 220 (as shown in FIG. 3a). Similarly, the volume of the first arm 311 and the frame 220 can be reduced, which is beneficial to the miniaturization of the camera module. In some embodiments, the first arm 311 can have a straight line type arm or a curved arm, etc.

[0154] The present embodiment does not limit the connection manner of the first deformation layer 421 and the elastic layer 423. Exemplarily, the first deformation layer 421 and the elastic layer 423 can be connected through a glue layer. Similarly, the second deformation layer 422 and the elastic layer 423 can be connected through a glue layer.

[0155] The present embodiment does not limit the connection manner of the arm body 410 and the elastic layer 423. Exemplarily, the arm body 410 and the elastic layer 423 can be connected through a glue layer. In FIG. 9, the arm body 410 has a glue containing hole 411, the glue containing hole 411 is filled with a glue layer, and the arm body 410 and the elastic layer 423 are connected through the glue layer in the glue containing hole 411.

[0156] The present embodiment does not limit the material of the elastic layer 423. Exemplarily, the material of the elastic layer 423 can include at least one of silicone, thermoplastic elastomer, thermoplastic polyurethane elastomer rubber, polyvinyl chloride soft glue, or rubber (such as silicone rubber, natural rubber, butadiene rubber, styrene butadiene rubber, and isoprene rubber, etc.). The foregoing materials have the characteristics of softness and elastic deformation, and the deformation of the elastic layer 423 made of the foregoing materials can provide space for the bending of the first deformation layer 421 and the second deformation layer 422. In some embodiments, in order to be aesthetically pleasing, the surface of the elastic layer 423 can be provided with a coating or a plating layer.

[0157] The material of the arm body 410 is not limited in the embodiments. In some embodiments, the arm body 410 is a rigid material. The rigid material is different from the flexible material, and the rigid material is not easy to deform. For example, the material of the arm body 410 includes at least one of metal, steel, carbon fiber, or plastic.

[0158] FIG. 10a is a trajectory diagram of the movement of the first arm 311 in the first state. Referring to FIG. 10a, in the first state, the first deformation layer 421 and the second deformation layer 422 are bent towards the a direction. The elastic layer 423 can deform, and the space generated by the deformation provides a bending space for the bending process of the first deformation layer 421 and the second deformation layer 422, avoiding tearing or damage of the first deformation layer 421 and the second deformation layer 422 due to the inability to release internal stress during the bending process. In addition, part of the kinetic energy generated during the bending process of the first deformation layer 421 and the second deformation layer 422 can be stored in the elastic layer 423, and the kinetic energy can make the first deformation layer 421 and the second deformation layer 422 recover.

[0159] During the bending process of the first deformation layer 421 and the second deformation layer 422, because the first end 301 is connected to the first frame 110 (as shown in FIG. 3a), the arm body 410 connected to the elastic layer 423 swings towards the a direction with the first end 301 as the center. In other words, the bending of the arm body 410 has a sub-movement in the a direction. The end of the arm body 410 away from the elastic layer 423 (i.e., the second end 302) moves towards the a direction, and the second end 302 outputs the force F11. When the force acts on the swing piece 313, the swing piece 313 rotates forward. In this way, in the first state, the first deformation layer 421 and the second deformation layer 422 are bent towards the a direction, and the second end 302 outputs the force F11 towards the a direction.

[0160] FIG. 10b is a trajectory diagram of the movement of the first arm 311 in the second state. In contrast to the aforementioned FIG. 10a, in FIG. 10b, in the second state, the first deformation layer 421 and the second deformation layer 422 are bent towards the b direction. The arm body 410 connected to the elastic layer 423 swings towards the b direction with the first end 301 as the center. In other words, the bending of the arm body 410 has a sub-movement in the b direction. The end of the arm body 410 away from the elastic layer 423 (i.e., the second end 302) moves towards the b direction, and the second end 302 outputs the force F12. When the force acts on the swing piece 313, the swing piece 313 rotates reversely.

[0161] The bending of the first deformation layer 421 and the second deformation layer 422 towards the a direction or the b direction has various implementation manners.

[0162] Figure 10c is a structural schematic diagram of the deformation assembly 420 in different states according to an embodiment of the present application. Referring to Figure 10c, in the initial state, the first deformation layer 421 and the second deformation layer 422 are not bent or have a small bending deformation. The elastic layer 423 can be regarded as being in a free state, i.e., there is almost no interaction force between the first deformation layer 421 and the elastic layer 423, and there is almost no interaction force between the second deformation layer 422 and the elastic layer 423.

[0163] In the first state, compared with the initial state, the first deformation layer 421 is lengthened and the second deformation layer 422 is shortened, so that the first deformation layer 421 and the second deformation layer 422 are bent towards the a direction. In the bending process, the elastic layer 423 between the first deformation layer 421 and the second deformation layer 422 is deformed to provide space for the bending of the first deformation layer 421 and the second deformation layer 422.

[0164] Similarly, in the second state, compared with the initial state, the first deformation layer 421 is shortened and the second deformation layer 422 is lengthened, so that the first deformation layer 421 and the second deformation layer 422 are bent towards the b direction. In the bending process, the elastic layer 423 is deformed to provide space for the bending of the first deformation layer 421 and the second deformation layer 422.

[0165] The first deformation layer 421 is lengthened in the first state and is shortened in the second state, which has various implementation manners. For example, the first deformation layer 421 includes piezoelectric material, electroactive artificial muscle material, thermoelectric deformation material, electrostatic deformation material, magnetic electro-deformation material, or asphalt mastic (Stone Mastic Asphalt, SMA) material.

[0166] The piezoelectric material is a crystal material that generates voltage between two end faces when subjected to pressure, and the crystal in the piezoelectric material will be distorted to convert electrical energy into mechanical energy under the action of electrical energy. Illustratively, the piezoelectric material can include at least one of a piezoelectric single crystal, a piezoelectric polycrystal (piezoelectric ceramic), a piezoelectric polymer, a piezoelectric composite material, and a piezoelectric semiconductor. The piezoelectric single crystal includes a piezoelectric quartz crystal, lithium niobate, lithium tantalate, Rochelle salt, ammonium dihydrogen phosphate, potassium dihydrogen phosphate, or dipotassium tartrate, etc. The piezoelectric polycrystal includes barium titanate, lead titanate, potassium sodium niobate, lead metaniobate, lead zirconate titanate, and lead barium metaniobate. The piezoelectric polymer includes polyvinylidene fluoride, etc.

[0167] The electroactive artificial muscle material can include a dielectric-elastomer (De). The pyroelectrically deformable material can include a shape memory polymer (SMP). The electrostatically deformable material can include an electrostatic actuator. The magnetoelectrically deformable material can include an electromagnetic actuator. Embodiments of the present application are described by way of example with the material of the first deformable layer 421 including a piezoelectric material. In FIG. 10c, in a first state, the first deformable layer 421 is applied with a first electric field E1, and the first deformable layer 421 grows. In a second state, the first deformable layer 421 is applied with a second electric field E2, and the first deformable layer 421 shortens, the first electric field E1 and the second electric field E2 are in opposite directions. In an initial state, the first deformable layer 421 is applied with a third electric field E3, and the first deformable layer 421 does not bend, the third electric field E3 is zero. In other words, in the initial state, the first deformable layer 421 is not applied with an electric field.

[0168] In this way, the growth or shortening of the first deformable layer 421 can be adjusted by adjusting the direction of the electric field applied to the first deformable layer 421. The growth or shortening of the second deformable layer 422 can be adjusted by adjusting the direction of the electric field applied to the second deformable layer 422.

[0169] Further, the polarization direction of the piezoelectric material and the electric field direction together determine the elongation or shortening of the piezoelectric material. For example, the electric field direction is the same as the polarization direction, and the first deformable layer 421 grows. The electric field direction is opposite to the polarization direction, and the first deformable layer 421 shortens.

[0170] In some embodiments, the deformation amount of the first deformable layer 421 growing or the deformation amount of the first deformable layer 421 shortening can be adjusted by adjusting the size of the electric field applied to the first deformable layer 421. Similarly, the deformation amount of the second deformable layer 422 growing or the deformation amount of the second deformable layer 422 shortening can be adjusted by adjusting the size of the electric field applied to the second deformable layer 422.

[0171] By adjusting the deformation amount of the first deformable layer 421 and the deformation amount of the second deformable layer 422, the radius of the bending of the deformable assembly 420 can be adjusted, so as to adjust the distance of the second end 302 (as shown in FIG. 10b) of the arm body 410 (as shown in FIG. 10b) connected with the deformable assembly 420 moving close to or away from the swing piece 313 (as shown in FIG. 10b), and the forces F11 (as shown in FIG. 5a) and F12 (as shown in FIG. 5b) transmitted to the second end 302 by the arm body 410.

[0172] In some embodiments of the present application, the deformation assembly 420 can further include a controller 424 configured to obtain deformation indication information and output a control instruction based on the indication information. The indication information is used to indicate the state of the camera module. For example, the indication information can come from the printed circuit board 16 of the electronic device 01.

[0173] The control instruction is used to control the electric field applied to the deformation assembly 420 to be the first electric field E1 when the indication information indicates that the camera module is in the first state. Alternatively, the control instruction is used to control the electric field applied to the deformation assembly 420 to be the second electric field E2 when the indication information indicates that the camera module is in the second state. Alternatively, the control instruction is used to control the electric field applied to the deformation assembly 420 to be the third electric field E3 when the indication information indicates that the camera module is in the initial state.

[0174] Please refer to FIG. 10b, as mentioned above, the first deformation layer 421 or the second deformation layer 422 serves as the first end 301, and the first end 301 is connected to the first frame 110. In some embodiments of the present application, the first arm 311 further includes a connecting portion 430, and the first end 301 is connected to the first frame 110 through the connecting portion 430.

[0175] For example, the connecting portion 430 can be a glue layer, a solder layer or a buckle.

[0176] For example, in the embodiment in which the first deformation layer 421 serves as the first end 301, the connecting portion 430 is connected to the side of the first deformation layer 421 away from the elastic layer 423. Similarly, in the embodiment in which the second deformation layer 422 serves as the first end 301, the connecting portion 430 is connected to the side of the second deformation layer 422 away from the elastic layer 423.

[0177] In the embodiments of the present application, the material, shape and structure of the second arm 312 can refer to the description of the first arm 311, which will not be repeated here.

[0178] Please refer to FIG. 3a, in some embodiments of the present application, the camera module 20 can further include a second driving assembly 320, a second frame 120 and a second rotating shaft 202. The second frame 120 is sleeved outside the first frame 110. The second frame 120 is rotationally connected to the first frame 110 through the second rotating shaft 202, and the second rotating shaft 202 and the second frame 120 are connected to the second driving assembly 320. The axis L1 of the first rotating shaft 210 and the axis L2 of the second rotating shaft 202 are perpendicular to each other.

[0179] When the camera module 20 is in the third state, the second frame body 120 rotates around the second virtual axis in a third reference direction, and the second driving assembly 320 drives the first frame body 110 to rotate around the axis L2 of the second rotating shaft 202 in a third direction. The third reference direction is opposite to the third direction, and the second virtual axis is parallel to the axis L2 of the second rotating shaft 202. When the camera module 20 is in the fourth state, the second frame body 120 rotates around the second virtual axis in a fourth reference direction, and the second driving assembly 320 drives the first frame body 110 to rotate around the axis L2 of the second rotating shaft 202 in a fourth direction. The third reference direction and the fourth reference direction are opposite to each other, and the fourth direction is opposite to the third direction. In this way, under the action of the second driving assembly 320, the first frame body 110 can rotate around the axis L2 of the second rotating shaft 202. For example, the rotation of the first frame body 110 around the axis L2 of the second rotating shaft 202 in the third direction can be regarded as the forward rotation of the first frame body 110 around the axis L2 of the second rotating shaft 202. Similarly, the rotation of the first frame body 110 around the axis L2 of the second rotating shaft 202 in the fourth direction can be regarded as the reverse rotation of the first frame body 110 around the axis L2 of the second rotating shaft 202.

[0180] The description of the relationship between the third direction and the third reference direction is the same as the description of the relationship between the first direction and the first reference direction. Please refer to the foregoing description.

[0181] Because the second frame body 120 is rotationally connected to the first frame body 110 through the second rotating shaft 202, and the first frame body 110 is rotationally connected to the lens holder 220 through the first rotating shaft 210, the first frame body 110, the first rotating shaft 210, and the lens holder 220 can rotate together relative to the second frame body 120. For example, the first frame body 110, the first rotating shaft 210, and the lens holder 220 can rotate together around the axis L2 of the second rotating shaft 202 in the third direction or the fourth direction (i.e., in the forward direction or the reverse direction around the axis L2). If the member connected to the second frame body 120 (for example, the middle frame of a mobile phone) shakes, the first frame body 110, the first rotating shaft 210, and the lens holder 220 can rotate together around the axis L2 of the second rotating shaft 202 to reduce the deviation of the lens holder 220 and improve the anti-shake performance. In addition, the first driving assembly is used to weaken the influence of the rotation of the first frame body around the first virtual axis in the first reference direction or the second reference direction on the lens holder 220, and the second driving assembly 320 is used to weaken the influence of the rotation of the second frame body around the second virtual axis in the third reference direction or the fourth reference direction on the lens holder 220, so as to correct the deviation of the lens holder 220 from multiple angles and further improve the image quality of the camera module 20.

[0182] As mentioned above, when the camera module 20 is in the first state, the first frame body 110 is tilted or shaken, so that the back side of the first frame body 110 is higher than the front side, and the first frame body 110 rotates around the first virtual axis in the first reference direction. When the camera module 20 is in the second state, the first frame body 110 is tilted or shaken, so that the front side of the first frame body 110 is higher than the back side, and the first frame body 110 rotates around the first virtual axis in the second reference direction.

[0183] In the embodiment of the present application, when the camera module 20 is in the third state, the second frame body 120 is tilted or shaken, so that the right side of the second frame body 120 is higher than the left side, which can be regarded as that the second frame body 120 rotates around the second virtual axis in the third reference direction. The second driving assembly 320 drives the first frame body 110, the first rotating shaft 210 and the lens holder 220 to rotate together around the axis L2 of the second rotating shaft 202 in the third direction, which can compensate the problem of large deflection angle between the lens holder 220 and the object to be photographed caused by the rotation of the second frame body 120 around the second virtual axis in the third reference direction.

[0184] Similarly, when the camera module 20 is in the fourth state, the second frame body 120 is tilted or shaken, so that the left side of the second frame body 120 is higher than the right side, which can be regarded as that the second frame body 120 rotates around the second virtual axis in the fourth reference direction. The second driving assembly 320 drives the lens holder 220 to rotate around the axis L2 of the second rotating shaft 202 in the fourth direction, which can compensate the problem of large deflection angle between the lens holder 220 and the object to be photographed caused by the rotation of the second frame body 120 around the second virtual axis in the fourth reference direction.

[0185] The structure of the second frame body 120 can refer to the structure description of the first frame body 110 described above. The connection mode of the second frame body 120 and the second rotating shaft 202 can refer to the description of the connection mode of the first frame body 110, the lens holder 220 and the first rotating shaft 210, which will not be described here.

[0186] In the embodiment in which the first frame body 110 is connected with the middle frame 13 or the rear shell 15, the first frame body 110 and the middle frame 13 or the rear shell 15 are connected through the second frame body 120.

[0187] The structure of the second driving assembly 320 can refer to the structure description of the first driving assembly 310 described above. Correspondingly, the connection mode of the second driving assembly 320 and the second rotating shaft 202 can refer to the description of the connection mode of the first driving assembly 310 and the first rotating shaft 210. The connection mode of the second driving assembly 320 and the second frame body 120 can refer to the description of the connection mode of the first driving assembly 310 and the first frame body 110, which will not be described here.

[0188] Exemplarily, the second driving assembly 320 comprises a third arm 321 and a fourth arm 322. The structures of the third arm 321 and the fourth arm 322 can refer to the description of the first arm 311.

[0189] In the embodiment in which the camera module 20 comprises the first driving assembly 310 and the second driving assembly 320, the first driving assembly 310 and the second driving assembly 320 can have various positional relationships.

[0190] FIG. 11a is a diagram of a positional relationship between the first driving assembly 310 and the second driving assembly 320 according to an embodiment of the present application. As shown in FIG. 11a, the lens holder 220 has a four-prism barrel structure, and in some embodiments, an arc transition is used at the prisms of the four-prism.

[0191] In FIG. 11a, the first arm 311 and the second arm 312 of the first driving assembly 310 are both located on the same side of the lens holder 220. The third arm 321 and the fourth arm 322 of the second driving assembly 320 are both located on the same side of the lens holder 220. The first driving assembly 310 and the second driving assembly 320 are located on two adjacent sides of the lens holder 220. In this way, the space on the side of the lens holder 220 on which no driving assembly is arranged can be utilized.

[0192] FIG. 11b is another diagram of a positional relationship between the first driving assembly 310 and the second driving assembly 320 according to an embodiment of the present application. In FIG. 11b, the first arm 311 and the second arm 312 of the first driving assembly 310 are respectively located on two adjacent sides of the lens holder 220. The third arm 321 and the fourth arm 322 of the second driving assembly 320 are respectively located on two adjacent sides of the lens holder 220. In this way, the space on the side of the lens holder 220 on which no driving assembly is arranged can be utilized.

[0193] The first arm 311 and the second arm 312 in FIGS. 11a and 11b are both in a strip or plate structure, and the extension path of the strip or plate structure is a straight line. The third arm 321 and the fourth arm 322 are the same.

[0194] FIG. 11c is still another diagram of a positional relationship between the first driving assembly 310 and the second driving assembly 320 according to an embodiment of the present application. In FIG. 11c, the first arm 311 is in an L shape, and the second arm 312 is in an L shape. The first driving assembly 310 is arranged around three outer sides of the lens holder 220. Similarly, the third arm 321 and the fourth arm 322 are in an L shape, and the second driving assembly 320 is arranged around three outer sides of the lens holder 220.

[0195] It can be understood that in other embodiments of the present application, the positional relationship between the first driving assembly 310 and the second driving assembly 320 is not limited to the relationship shown in FIGS. 11a, 11b and 11c. The positional relationship can be set according to the size of the space of the camera module.

[0196] In addition, in FIGS. 11a, 11b and 11c, the first driving assembly 310 and the second driving assembly 320 are located at the outer periphery of the frame 220. In other embodiments, the first driving assembly 310 and the second driving assembly 320 can also be located at the bottom of the frame 220, in other words, the first driving assembly 310 and the second driving assembly 320 can also be located at the image side of the frame 220.

[0197] In some embodiments of the present application, the driving assembly can not adopt the structure of the first driving assembly 310 described above. The following is described by way of example in combination with FIGS. 12a and 12b.

[0198] FIG. 12a is a structural schematic diagram of another camera module 20 provided by an embodiment of the present application. Please refer to FIG. 12a, the difference between FIG. 12a and FIG. 3a is that the driving assembly 40 is different and FIG. 12a can include the first rotation shaft in FIG. 3a. The structures of the first housing 110 and the frame 220 please refer to the description of FIG. 3a above, which will not be described here again.

[0199] FIG. 12b is a structural schematic diagram of the frame 220 and the driving assembly 40 in the example shown in FIG. 12a. In FIG. 12b, the driving assembly 40 includes the first arm 311, the second arm 312, the first gimbal 401 and the second gimbal 402. The first end 301 of the first arm 311 is connected with the first housing 110. The third end 303 of the second arm 312 is connected with the first housing 110. The second end 302 of the first arm 311 is connected with the frame 220 through the first gimbal 401. The fourth end 304 of the second arm 312 is connected with the frame 220 through the second gimbal 402. When the second end 302 and the fourth end 304 move, the movement of the second end 302 and the fourth end 304 will be transmitted to the frame 220, so as to make the frame 220 move.

[0200] When the camera module is in the first state, the first housing 110 rotates around the first virtual axis along the first reference direction, the first arm 311 drives the first gimbal to rotate around the first virtual axis along the first direction, and the first reference direction is opposite to the first direction. In this way, the influence of the rotation of the first housing 110 on the frame 220 is weakened.

[0201] For example, in FIG. 12a, when the second end 302 moves towards the front side and the fourth end 304 moves towards the back side, the second end 302 will exert a force towards the front side on the frame 220, and the fourth end 304 will exert a force towards the back side on the frame 220, so as to make the frame 220 rotate in the positive direction. Conversely, when the second end 302 moves towards the back side and the fourth end 304 moves towards the front side, the second end 302 will exert a force towards the back side on the frame 220, and the fourth end 304 will exert a force towards the front side on the frame 220, so as to make the frame 220 rotate in the reverse direction.

[0202] It can be understood that, in some embodiments, the second arm 312 and the second universal joint 402 can be unnecessary.

[0203] In some embodiments, the driving assembly 40 can further include a third universal joint 403, a fourth universal joint 404, a fifth arm 041 and a sixth arm 042. One end of the fifth arm 041 is connected with the first frame 110, and the other end of the fifth arm 041 is connected with the frame 220 through the third universal joint 403. One end of the sixth arm 042 is connected with the first frame 110, and the other end of the sixth arm 042 is connected with the frame 220 through the fourth universal joint 404. The fifth arm 041 and the sixth arm 042 can make the first frame 110 and the frame 220 have multiple force points, and can make the rotation of the frame 220 more stable.

[0204] As shown in FIG. 12b, when the fifth arm 041 and the second end 302 exert a force towards the front side on the frame 220, and the fourth end 304 and the sixth arm 042 exert a force towards the rear side on the frame 220, the frame 220 rotates forward around the n1 axis. Conversely, when the fifth arm 041 and the second end 302 exert a force towards the rear side on the frame 220, and the fourth end 304 and the sixth arm 042 exert a force towards the front side on the frame 220, the frame 220 rotates reversely around the n1 axis. In this way, the fifth arm 041 and the sixth arm 042 have the effect of increasing the torque when the frame 220 rotates.

[0205] In addition, the fifth arm 041 and the sixth arm 042 can increase the degree of freedom of the frame 220. When the sixth arm 042 and the second end 302 exert a force towards the front side on the frame 220, and the fourth end 304 and the fifth arm 041 exert a force towards the rear side on the frame 220, the frame 220 rotates forward around the n2 axis. Conversely, when the sixth arm 042 and the second end 302 exert a force towards the rear side on the frame 220, and the fourth end 304 and the fifth arm 041 exert a force towards the front side on the frame 220, the frame 220 rotates reversely around the n2 axis.

[0206] In the embodiments of the present application, the included angle between adjacent two arms of the fifth arm 041, the sixth arm 042, the first arm 311 and the second arm 312 is not limited. For example, the included angle between adjacent two arms of the fifth arm 041, the sixth arm 042, the first arm 311 and the second arm 312 is 70°-100°, for example, can be 70°, 80°, 90°, 100°, etc.

[0207] It can be understood that, in some embodiments, the number of arms of the driving assembly 40 can be two, three, four or more, and the embodiments of the present application are not limited to this.

[0208] The structures of the fifth arm 041, the sixth arm 042, the first arm 311 and the second arm 312 of the driving assembly 40 are described in the foregoing description of the first arm 311 of the first driving assembly 310, and are not described herein again.

[0209] It can be understood that the structure of the second driving assembly 320 in the foregoing FIG. 3a can also adopt the driving assembly 40 shown in FIG. 12b.

[0210] Please return to FIG. 3a. In some embodiments of the present application, the electronic device can further include a flexible interconnection assembly 50. One end of the flexible interconnection assembly 50 is electrically connected with the printed circuit board 16 (as shown in FIG. 1). The other end of the flexible interconnection assembly 50 is electrically connected with the camera module. For example, the printed circuit board 16 and the lens module 201 are electrically connected through the flexible interconnection assembly 50. The other end of the flexible interconnection assembly 50 is electrically connected with the image sensor of the lens module 201.

[0211] Exemplarily, the flexible interconnection assembly 50 can be a flexible printed circuit (FPC).

[0212] In some embodiments, the first frame body 110 and the frame 220 jointly enclose the accommodation space 102, and at least part of the flexible interconnection assembly 50 is located in the accommodation space 102. In this way, at least part of the flexible interconnection assembly 50 is accommodated between the first frame body 110 and the frame 220. The space between the first frame body 110 and the frame 220 can be fully utilized, which is conducive to the miniaturization of the camera module 20.

[0213] Here, at least part of the flexible interconnection assembly 50 is located in the accommodation space 102, and the volume of the components of the flexible interconnection assembly 50 exposed outside the camera module 20 is small. The electronic device can provide a smaller space for accommodating the flexible interconnection assembly 50 exposed outside the camera module 20.

[0214] In some embodiments, the flexible interconnection assembly 50 is connected with the first frame body 110. In this way, during the disassembly of the camera module 20 and the lens module 201, the camera module 20 and the flexible interconnection assembly 50 can be separated from the lens module 201 together. In other words, the camera module 20 and the flexible interconnection assembly 50 can be regarded as one module, which can be applicable to more types of lens modules 201. The adaptability of the camera module 20 and the flexible interconnection assembly 50 is increased.

[0215] In the embodiment in which the camera module 20 includes the second frame body 120, the second frame body 120 and the first frame body 110 jointly enclose the accommodation space 103, and at least part of the flexible interconnection assembly 50 is located in the accommodation space 103. In this way, the volume of the components of the flexible interconnection assembly 50 exposed outside the camera module 20 is small.

[0216] FIG. 13 is a structural schematic diagram of a flexible interconnection assembly 50 according to an embodiment of the present application. Referring to FIG. 13, the flexible interconnection assembly 50 includes a first conductive segment 501, a second conductive segment 502, and a flexible conductive segment 503, which are connected in series.

[0217] The first conductive segment 501 is electrically connected to the printed circuit board 16 (shown in FIG. 1) at an end away from the flexible conductive segment 503. The second conductive segment 502 is electrically connected to the camera module 20 (shown in FIG. 1) at an end away from the flexible conductive segment 503. At least a portion of the flexible conductive segment 503 is located in the accommodating space 102 (shown in FIG. 3a).

[0218] Exemplarily, the first conductive segment 501 is connected to the first frame 110 (shown in FIG. 3b), and the second conductive segment 502 is connected to the frame 220 (shown in FIG. 3b). Since the first frame 110 and the frame 220 are rotationally connected, the first conductive segment 501 and the second conductive segment 502 can rotate relative to each other. The flexible conductive segment 503 connecting the first conductive segment 501 and the second conductive segment 502 can buffer the stress generated by the relative rotation of the first conductive segment 501 and the second conductive segment 502, thereby avoiding damage to the flexible interconnection assembly 50 during the rotation of the first frame 110 and the frame 220.

[0219] Exemplarily, the flexible conductive segment 503 is curved. During the relative rotation of the first conductive segment 501 and the second conductive segment 502, the curved flexible conductive segment 503 has a large stretching allowance, thereby avoiding tearing of the first conductive segment 501 and the second conductive segment 502.

[0220] In some embodiments, the flexible conductive segment 503 has a greater degree of curvature than the first conductive segment 501. In other words, the length of the signal line in the same area of the flexible conductive segment 503 is greater than the length of the signal line in the same area of the first conductive segment 501. In this way, the flexibility of the flexible conductive segment 503 is better than that of the first conductive segment 501. The flexibility of the flexible conductive segment 503 is better than that of the second conductive segment 502 for the same reason.

[0221] The above merely provides a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
