Camera modules and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on August 4, 2023, with application number 202310986626.3, and priority to the Chinese patent application with the invention name “Camera module and electronic device”, all contents of which are incorporated by reference into this application. Technical Field

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

[0003] With the widespread adoption and development of smartphones, mobile photography has become a common method of photography. Furthermore, phones with both optical image stabilization and autofocus are increasingly popular. Traditional camera modules consist of a gimbal module and a camera body. The gimbal module achieves image stabilization by controlling the movement of the camera body perpendicular to the optical axis. However, the irrational design of the gimbal module results in a large camera module.

[0004] Summary of the Invention

[0005] The embodiments of the present application provide a camera module and an electronic device including the camera module, aiming to obtain a small-sized camera module.

[0006] In a first aspect, a camera module is provided. The camera module includes a camera body, a first carrier, a second carrier, a first drive mechanism, and a second drive mechanism. Exemplarily, the camera body is used to collect light and convert image information carried by the light into electrical signals.

[0007] The first carrier is arranged around the camera subject, and the second carrier is arranged around the first carrier;

[0008] The camera body is rotatably connected to the first carrier, and the first driving mechanism is used to drive the camera body to rotate relative to the first carrier around a first rotation axis;

[0009] The second carrier is rotatably connected to the first carrier, and the second driving mechanism is used to drive the first carrier to drive the camera body to rotate relative to the second carrier around a second rotation axis. The extension direction of the first rotation axis and the extension direction of the second rotation axis intersect with the optical axis direction of the camera module.

[0010] It is understandable that when the camera module collects light, if the electronic device is shaken due to external force, the shaking stroke of the camera body can be offset by controlling the camera body to rotate around the first rotation axis and / or around the second rotation axis, so as to avoid or reduce the position deviation of the camera body caused by the shaking. In other words, the camera module of the present application can control the camera body to rotate around the first rotation axis and / or around the second rotation axis through the gimbal module, thereby realizing optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0011] In this embodiment, the first carrier is arranged to surround the imaging subject, and the second carrier is arranged to surround the first carrier. In this case, the imaging subject, the first carrier and the second carrier are arranged substantially in a nested manner.

[0012] It can be understood that the first carrier of this embodiment has a "one-item-multiple-purposes" function. On the one hand, the first carrier can cooperate with the second carrier to serve as a stator for rotating the camera body around the first rotation axis. On the other hand, the first carrier can serve as a mover for rotating the camera body around the second rotation axis. In this way, the first carrier can play a role in structural reuse, thereby simplifying the structure of the gimbal module and achieving a miniaturized gimbal module.

[0013] In addition, the second carrier of this embodiment also has the function of "one thing for multiple uses". The second carrier can cooperate with the first carrier to serve as a stator for the camera body to rotate around the first rotation axis. On the other hand, the second carrier can serve as a stator for the camera body to rotate around the second rotation axis. In this way, the second carrier can serve as a stator of a component of the camera module. In addition, the second carrier can be arranged around the first carrier, and the second carrier has the function of protecting the first carrier, the first drive mechanism and the second drive mechanism of the pan-tilt module. In this way, the second carrier can play a role of structural reuse, thereby simplifying the structure of the pan-tilt module, thereby realizing the miniaturization setting of the pan-tilt module.

[0014] It can be understood that the second carrier can serve as a stator of a component of the camera module, and can also protect the first carrier, the first drive mechanism and the second drive mechanism of the pan-tilt module. In this way, when the camera module is applied to an electronic device, the second carrier of the pan-tilt module can be directly fixed on the structural member (such as a shell or a middle frame) of the electronic device. In this way, compared with the traditional camera module solution: a shell needs to be provided on the outside of the pan-tilt module of the camera module, and the camera module is packaged and fixed to the structural member (such as a shell or a middle frame) of the electronic device through the shell. In this embodiment, since the second carrier of the pan-tilt module can be directly fixed on the structural member (such as a shell or a middle frame) of the electronic device, the camera module does not need to be additionally provided with a shell, thereby further simplifying the structure of the camera module, which is conducive to the miniaturization of the camera module. In addition, the step of fixing the camera module to the structural member (such as a shell or a middle frame) of the electronic device through the shell can be omitted, thereby reducing the cost investment.

[0117] FIG1 is a schematic structural diagram of an electronic device 1000 provided in an embodiment of the present application.

[0118] As shown in FIG1 , electronic device 1000 may be a device with a camera function, such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, an in-vehicle device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet. The electronic device 1000 of the embodiment shown in FIG1 is described using a mobile phone as an example.

[0119] FIG2 is a partial cross-sectional view of the electronic device 1000 shown in FIG1 taken along line AA in one embodiment.

[0120] As shown in Figures 1 and 2, the electronic device 1000 may include a camera module 100, a device housing 200, and a screen 300. The camera module 100 may be a rear camera module or a front camera module. It should be noted that Figure 1 and the related figures below only schematically illustrate some components included in the electronic device 1000, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1 and the figures below. In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may also not include the screen 300.

[0121] As shown in Figures 1 and 2, the device housing 200 may include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. For example, the back cover 202 may be fixed to the frame 201 by adhesive. The back cover 202 may also be integrally formed with the frame 201, that is, the back cover 202 and the frame 201 form a single unitary structure.

[0122] In one embodiment, the screen 300 can be located on the side of the frame 201 away from the back cover 202. In this case, the screen 300 and the back cover 202 can be located on either side of the frame 201. The screen 300, the frame 201, and the back cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, a receiver, or a microphone. The screen 300 can be either flat or curved.

[0123] For example, the camera module 100 can be located inside the electronic device 1000. The camera module 100 can be located on the side of the screen 300 facing the back cover 202. The back cover 202 can have a light hole 203. The shape of the light hole 203 is not limited to the circular shape shown in FIG1. ​​The light hole 203 connects the interior of the electronic device 1000 to the exterior of the electronic device 1000. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light hole 203. The camera module 100 can collect light entering the interior of the electronic device 1000.

[0124] For example, the camera module 100 can be a common camera module (i.e., the optical axis direction of the camera module 100 is the Z-axis direction). In some embodiments, the camera module 100 can also be a periscope camera module (i.e., the optical axis direction of the camera module 100 is any direction on the XY plane). It will be understood that the camera module 100 of this embodiment is described using a common camera module as an example.

[0125] For ease of description, the width direction of the camera module 100 is defined as the X-axis. The length direction of the camera module 100 is defined as the Y-axis. The thickness direction of the camera module 100 is defined as the Z-axis. It is understood that the coordinate system setting of the camera module 100 can be flexibly set according to specific actual needs. In this embodiment, the X-axis direction is the first direction, the Y-axis direction is the second direction, and the Z-axis direction is the third direction.

[0126] Fig. 3 is a schematic structural diagram of an embodiment of the camera module 100 shown in Fig. 1. Fig. 4 is a partially exploded schematic diagram of an embodiment of the camera module 100 shown in Fig. 3.

[0127] As shown in Figures 3 and 4, the camera module 100 may include a camera body 1 and a pan / tilt module 2. The camera body 1 is disposed on the pan / tilt module 2.

[0128] Exemplarily, the camera body 1 is used to collect light and convert image information carried by the light into electrical signals.

[0129] For example, the gimbal module 2 can control the camera body 1 to rotate about a first rotation axis P1 and a second rotation axis P2. The extension direction of the first rotation axis P1, the extension direction of the second rotation axis P2, and the optical axis direction of the camera module 100 intersect with each other. It is understood that the first rotation axis P1 and the second rotation axis P2 can be extensions of a physical axis or a virtual axis.

[0130] Exemplarily, the extension direction of the first rotation axis P1 can be the X-axis direction. The extension direction of the second rotation axis P2 can be the Y-axis direction. The optical axis direction of the camera module 100 is the Z-axis direction. It can be understood that the gimbal module 2 can independently control the camera subject 1 to rotate around the first rotation axis P1, can independently control the camera subject 1 to rotate around the second rotation axis P2, and can simultaneously control the camera subject 1 to rotate around both the first rotation axis P1 and the second rotation axis P2. For example, when the gimbal module 2 independently controls the camera subject 1 to rotate around the first rotation axis P1, since the extension direction of the first rotation axis P1 is the X-axis direction, the camera subject 1 rotates along a plane that is perpendicular to the X-axis direction (i.e., the YZ plane). When the gimbal module 2 independently controls the camera subject 1 to rotate around the second rotation axis P2, since the extension direction of the second rotation axis P2 is the Y-axis direction, the camera subject 1 can rotate along a plane that is perpendicular to the Y-axis direction (i.e., the XZ plane). When the gimbal module 2 simultaneously controls the camera body 1 to rotate around the first rotation axis P1 and the second rotation axis P2, since the extension direction of the first rotation axis P1 is the X-axis direction and the extension direction of the second rotation axis P2 is the Y-axis direction, the camera body 1 can rotate around both the X-axis and the Y-axis.

[0131] It is understandable that the pan-tilt module 2 can control the camera subject 1 to rotate around the X-axis and / or around the Y-axis. When the camera module collects light, if the electronic device is shaken due to external force, the pan-tilt module 2 can be used to control the camera subject 1 to rotate around the X-axis and / or around the Y-axis to offset the shaking stroke generated by the camera subject 1, so as to avoid or reduce the position bias of the camera subject 1 caused by the shaking. In other words, the camera module 100 of the present application can control the camera subject 1 to rotate around the X-axis and / or around the Y-axis through the pan-tilt module 2 to achieve optical image stabilization (OIS) of the camera module and improve the imaging quality of the camera module. It is understandable that the anti-shake control of the camera subject 1 by the pan-tilt module 2 can be large-angle and low-frequency anti-shake. For example, the anti-shake angle of the pan-tilt module 2 of this embodiment is greater than 0.8° and the frequency is less than 4Hz.

[0132] Fig. 5 is a partially exploded view of the camera body 1 shown in Fig. 4 in one embodiment. Fig. 6 is a partially exploded view of the camera body 1 shown in Fig. 5 at another angle.

[0133] Referring to Figures 5 and 6 , in conjunction with Figure 4 , the camera body 1 includes a lens assembly 11 and an image sensor assembly 12. The image sensor assembly 12 is located on the light-emitting side of the lens assembly 11 and is fixedly connected to the lens assembly 11. The lens assembly 11 is configured to collect light and converge it onto the image sensor assembly 12. The image sensor assembly 12 collects the light and converts the image information carried by the light into an electrical signal.

[0134] It is understood that the camera body 1 may further include further structures. For example, the camera body 1 may further include a variable aperture (not shown). The variable aperture is located on the light-entering side of the lens assembly 11 and is fixedly connected to the lens assembly 11. The aperture size of the variable aperture can be automatically adjusted. Light can enter the lens assembly 11 through the aperture of the variable aperture.

[0135] As shown in Figures 5 and 6, the lens assembly 11 includes a first housing 11a and a focus lens 11b. The focus lens 11b can move along the Z-axis to achieve auto focus (AF). The first housing 11a is provided with a first through-hole 11c. The first through-hole 11c connects the interior and exterior of the first housing 11a. The focus lens 11b is mounted inside the first housing 11a, with a portion of the focus lens 11b exposed outside the first housing 11a through the first through-hole 11c.

[0136] It is understood that the structures of the first housing 11a and the focus lens 11b can both adopt conventional first housing and focus lens structures, and this application does not limit the specific structure. In addition, the lens assembly 11 can include more or fewer structures. For example, when the lens assembly 11 does not include the focus lens 11b, the lens assembly 11 includes a fixed-focus lens.

[0137] 5 and 6 , the first housing 11a includes a first side portion 111 and a second side portion 112 disposed opposite to each other, a second sub-side portion 1132 and a fourth side portion 114 disposed opposite to each other. The second sub-side portion 1132 and the fourth side portion 114 are connected between the first side portion 111 and the second side portion 112.

[0138] Exemplarily, the second sub-side portion 1132 includes a first sub-side portion 1131, a second sub-side portion 1132, and a third sub-side portion 1133 that are sequentially connected. The first sub-side portion 1131 is connected to the first side portion 111. The third sub-side portion 1133 is connected to the second side portion 112.

[0139] Exemplarily, the angle between the first sub-side portion 1131 and the second sub-side portion 1132 and the angle between the second sub-side portion 1132 and the third sub-side portion 1133 are both obtuse angles.

[0140] Exemplarily, the fourth side portion 114 includes a fourth sub-side portion 1141, a fifth sub-side portion 1142, and a sixth sub-side portion 1143 connected in sequence. The fourth sub-side portion 1141 is connected to the second side portion 112. The sixth sub-side portion 1143 is connected to the first side portion 111.

[0141] Exemplarily, the included angle between the fourth sub-side portion 1141 and the fifth sub-side portion 1142 and the included angle between the fifth sub-side portion 1142 and the sixth sub-side portion 1143 are both obtuse angles.

[0142] Exemplarily, the cross-section of the first housing 11 a parallel to the XY plane is substantially octagonal.

[0143] The first housing 11a is further provided with a first rotating shaft 111a and a second rotating shaft 111b. The first rotating shaft 111a and the second rotating shaft 111b may be on the same straight line, that is, the first rotating shaft 111a and the second rotating shaft 111b are colinear. The first rotating shaft 111a and the second rotating shaft 111b are protruding from the outer surface of the first housing 11a. An extension of the centerline of the first rotating shaft 111a or an extension of the centerline of the second rotating shaft 111b may constitute the first rotation axis P1. It is understood that the first housing 11a may be integrally formed with the first rotating shaft 111a. The first housing 11a may be integrally formed with the second rotating shaft 111b.

[0144] For example, the first rotation axis 111a is protruded from the first side portion 111 of the first housing 11a. The second rotation axis 111b is protruded from the second side portion 112 of the first housing 11a. The first rotation axis 111a and the second rotation axis 111b may be parallel to the X-axis direction.

[0145] FIG. 7 is a partial cross-sectional view of the image sensor assembly 12 shown in FIG. 5 taken along line BB according to an embodiment.

[0146] As shown in Figure 7, the image sensor assembly 12 includes a module circuit board 121, an image sensor 122, a filter holder 123, and a filter 124. In some embodiments, the image sensor 122 can be fixed to the module circuit board 121 and electrically connected to the module circuit board 121. In this case, signals can be transmitted between the image sensor 122 and the module circuit board 121. The filter holder 123 is fixedly connected to the module circuit board 121. The filter holder 123 and the image sensor 122 are located on the same side of the module circuit board 121. The filter holder 123 is provided with a light-transmitting hole 125. The filter 124 is fixedly connected to the filter holder 123. The filter 124 can be located within the light-transmitting hole 125. The filter 124 is also positioned opposite the image sensor 122. The filter 124 can be used to filter infrared light, blue light, and other light from light entering the image sensor 122, thereby ensuring that the image sensor 122 has excellent imaging quality.

[0147] As shown in Figures 6 and 7 , when the image sensor assembly 12 is fixed to the light-exiting side of the lens assembly 11, the image sensor 122, the optical filter 124, and the focus lens 11b are arranged in sequence along the Z-axis. In this case, the image sensor 122 is located on the light-exiting side of the focus lens 11b. The optical filter 124 is located between the focus lens 11b and the image sensor 122.

[0148] Illustratively, the image sensor assembly 12 includes a second housing 126. The second housing 126 can be fixed to the module circuit board 121 or to the filter holder 123. The image sensor 122, the filter holder 123, and the filter 124 can be located inside the second housing 126. The second housing 126 can be used to protect the image sensor 122, the filter holder 123, and the filter 124. In addition, the second housing 126 is provided with a second through hole 127, which connects the interior and exterior of the second housing 126. The first housing 11a of the lens assembly 11 can be fixed to the second housing 126 by adhesive or the like. In the Z-axis direction, the focus lens 11b can be arranged opposite the filter 124 and the image sensor 122 through the second through hole 127 of the second housing 126.

[0149] It is understandable that the image sensor assembly 12 may further include an anti-shake motor (not shown). The anti-shake motor may be fixed to the module circuit board 121. The anti-shake motor is used to control the movement of the image sensor 122 along a plane perpendicular to the third direction Z (i.e., the XY plane). In this way, when the camera module 100 collects ambient light, if the electronic device 1000 vibrates in the XY plane due to external force, the anti-shake motor may be used to control the movement of the image sensor 122 in the XY plane to offset the shaking stroke of the focus lens 11b in the XY plane, thereby avoiding or reducing the position offset of the focus lens 11b caused by the shaking. In other words, the camera module 100 of the present application may control the movement of the image sensor 122 in the XY plane through the anti-shake motor to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100. It is understandable that the anti-shake of the image sensor 122 controlled by the anti-shake motor may be small-angle and high-frequency anti-shake. For example, the anti-shake angle of the anti-shake motor is less than 0.8° and the frequency is greater than 4 Hz. The relevant structure of the anti-shake motor will be described in detail later with reference to the relevant drawings.

[0150] The above describes in detail the structure of the camera module 100 and the camera body 1 of the camera module 100 in conjunction with the relevant drawings. The following describes in detail the structure of the pan / tilt module 2 and the connection relationship between the pan / tilt module 2 and the camera body 1 in conjunction with the relevant drawings.

[0151] FIG8 is a partial exploded view of the pan / tilt module 2 shown in FIG4 in one embodiment.

[0152] As shown in FIG8 , the pan / tilt module 2 includes a first carrier 21 , a second carrier 22 , a first driving mechanism 23 and a second driving mechanism 24 .

[0153] Figure 9 is a partially exploded view of the first carrier 21 shown in Figure 8 in one embodiment. Figure 10 is a partially exploded view of the first carrier 21 shown in Figure 9 at another angle. Figure 11 is a partially exploded view of the first carrier 21 shown in Figure 9 at yet another angle.

[0154] As shown in FIG. 9 to FIG. 11 , the first carrier 21 includes a first bracket 21 a , a first fixing member 21 b and a second fixing member 21 c .

[0155] Illustratively, the first bracket 21 a includes a first side portion 211 and a second side portion 212 that are oppositely disposed, and a third side portion 213 and a fourth side portion 214 that are oppositely disposed.

[0156] Exemplarily, the third side 213 of the first bracket 21a includes a first sub-side 2131, a second sub-side 2132 and a third sub-side 2133 connected in sequence, the first sub-side 2131 is connected to the first side 211 of the first bracket 21a, and the third sub-side 2133 is connected to the second side 212 of the first bracket 21a.

[0157] Exemplarily, the angle between the first sub-side portion 2131 and the second sub-side portion 2132 and the angle between the second sub-side portion 2132 and the third sub-side portion 2133 are both obtuse angles.

[0158] Illustratively, the fourth side 214 of the first bracket 21a includes a fourth sub-side 2141 , a fifth sub-side 2142 and a sixth sub-side 2143 connected in sequence. The fourth sub-side 2141 is connected to the second side 212 , and the sixth sub-side 2143 is connected to the first side 211 .

[0159] Exemplarily, the included angle between the fourth sub-side portion 2141 and the fifth sub-side portion 2142 and the included angle between the fifth sub-side portion 2142 and the sixth sub-side portion 2143 are both obtuse angles.

[0160] Exemplarily, the cross section of the first bracket 21 a parallel to the XY plane is substantially octagonal.

[0161] It is understood that the first bracket 21a may include fewer or more structures. For example, when the first bracket 21a includes fewer structures, the cross-section of the first bracket 21a parallel to the XY plane may be a quadrilateral, pentagon, hexagon, or heptagon. When the first bracket 21a includes more structures, the cross-section of the first bracket 21a parallel to the XY plane may be an n-gon, where n is greater than 8.

[0162] For example, the angle between two adjacent sides is 135°. In this case, the first bracket 21a is substantially in the shape of a regular octagon.

[0163] As shown in Figures 9 to 11, the first bracket 21a is provided with a first groove 251 and a second groove 252 which are oppositely arranged. The first groove 251 and the second groove 252 form openings on the inner surface and the bottom surface of the first bracket 21a.

[0164] Exemplarily, the first groove 251 is located at the first side portion 211 of the first bracket 21 a , and the second groove 252 is located at the second side portion 212 of the first bracket 21 a .

[0165] Exemplarily, the first groove 251 includes a first groove sidewall 253 and a second groove sidewall 254 that are oppositely disposed. The angle between the first groove sidewall 253 and the second groove sidewall 254 of the first groove 251 is an acute angle.

[0166] It is understandable that the second groove 252 and the first groove 251 adopt a similar or identical configuration.

[0167] As shown in Figure 11, the first bracket 21a is further provided with a first protrusion 255 and a second protrusion 256. The first protrusion 255 and the second protrusion 256 are protruded from the inner surface of the first bracket 21a.

[0168] Exemplarily, the first protrusion 255 and the second protrusion 256 are protruded from the inner surface of the second sub-side portion 2132 of the third side portion 213 .

[0169] It is understandable that, although FIG. 11 shows that the first bump 255 and the second bump 256 are spaced apart from each other, the first bump 255 may also be connected to the second bump 256 , in which case the first bump 255 and the second bump 256 form one bump.

[0170] As shown in Figures 9 and 10, the first bracket 21a is further provided with a third protrusion 257 and a fourth protrusion 258. The third protrusion 257 and the fourth protrusion 258 are protruded from the inner surface of the first bracket 21a.

[0171] Exemplarily, the third protrusion 257 and the fourth protrusion 258 are protruded from the inner surface of the fifth sub-side portion 2142 of the fourth side portion 214 .

[0172] It is understandable that, although FIG9 and FIG10 illustrate that the third bump 257 and the fourth bump 258 are spaced apart, the third bump 257 may also be connected to the fourth bump 258 , in which case the third bump 257 and the fourth bump 258 form one bump.

[0173] As shown in Figures 9 to 11, the first bracket 21a further includes a third rotating shaft 259a and a fourth rotating shaft 259b. The third rotating shaft 259a and the fourth rotating shaft 259b can be co-linear. The third rotating shaft 259a and the fourth rotating shaft 259b are protruding from the outer surface of the first bracket 21a. An extension of the centerline of the third rotating shaft 259a or the extension of the centerline of the fourth rotating shaft 259b can constitute the second rotation axis P2.

[0174] Illustratively, the third rotation axis 259a is located on the outer surface of the second sub-side 2132 of the third side 213 of the first bracket 21a. The fourth rotation axis 259b is located on the outer surface of the fifth sub-side 2142 of the fourth side 214 of the first bracket 21a. The third rotation axis 259a and the fourth rotation axis 259b can be parallel to the Y-axis direction.

[0175] Exemplarily, the third rotating shaft 259a and the fourth rotating shaft 259b are both cylindrical.

[0176] For example, the third rotating shaft 259a and the first bracket 21a may be an integrally formed structure. The fourth rotating shaft 259b and the first bracket 21a may be an integrally formed structure.

[0177] FIG12 is a schematic diagram of a partial structure of the camera module 100 shown in FIG3 in one embodiment.

[0178] As shown in FIG12 , the camera body 1 is located inside the first bracket 21 a. In other words, the first bracket 21 a can be disposed around the camera body 1. For example, the first bracket 21 a can be disposed around the lens assembly 11 of the camera body 1.

[0179] Illustratively, the first side portion 111 of the first housing 11a of the lens assembly 11 is opposite to and spaced from the first side portion 211 of the first bracket 21a. The second side portion 112 of the first housing 11a of the lens assembly 11 is opposite to and spaced from the second side portion 212 of the first bracket 21a. The first sub-side portion 1131 of the first housing 11a of the lens assembly 11 is opposite to and spaced from the first sub-side portion 2131 of the first bracket 21a. The second sub-side portion 1132 of the first housing 11a of the lens assembly 11 is opposite to and spaced from the second sub-side portion 2132 of the first bracket 21a. The third sub-side portion 1133 of the first housing 11a of the lens assembly 11 is opposite to and spaced from the third sub-side portion 2133 of the first bracket 21a. The fourth sub-side portion 1141 of the first housing 11a of the lens assembly 11 is opposite to and spaced from the fourth sub-side portion 2141 of the first bracket 21a. The fifth sub-side portion 1142 of the first housing 11a of the lens assembly 11 is opposite to and spaced from the fifth sub-edge portion 2142 of the first bracket 21a. The sixth sub-side portion 1143 of the first housing 11a of the lens assembly 11 is opposite to and spaced from the sixth sub-edge portion 2143 of the first bracket 21a.

[0180] FIG13 is a partial cross-sectional view of an embodiment of the camera module 100 shown in FIG12 taken along line CC.

[0181] As shown in FIG13 , at least a portion of the first rotating shaft 111 a of the lens assembly 11 is located within the first groove 251 of the first bracket 21 a and is rotatably connected to the wall of the first groove 251. The first fixing member 21 b is fixed to the first bracket 21 a and covers the first groove 251. The first fixing member 21 b is used to prevent the first rotating shaft 111 a from falling out of the first groove 251.

[0182] It is understandable that the first fixing member 21b can be fixed to the bottom surface of the first bracket 21a, or fixed in the first groove 251. In addition, the first fixing member 21b can cover the entire first groove 251, or can cover part of the first groove 251.

[0183] Exemplarily, the first fixing member 21b may be a metal sheet, such as a steel sheet or an aluminum sheet.

[0184] In other embodiments, the positions of the first rotation axis 111 a of the lens assembly 11 and the first groove 251 of the first bracket 21 a can be swapped.

[0185] FIG14 is a schematic diagram of a partial structure of the camera module 100 shown in FIG12 in one embodiment.

[0186] As shown in Figures 13 and 14 , for example, the first fixing member 21b supports the first rotating shaft 111a. The first fixing member 21b, the first groove sidewall 253 of the first groove 251, and the second groove sidewall 254 of the first groove 251 can roughly form a triangle. In this case, the first fixing member 21b, the first groove sidewall 253 of the first groove 251, and the second groove sidewall 254 of the first groove 251 can provide three-point support for the first rotating shaft 111a. This improves the stability of the connection between the first rotating shaft 111a and the first bracket 21a.

[0187] As shown in Figure 13, at least a portion of the second rotation shaft 111b of the lens assembly 11 is located within the second groove 252 of the first bracket 21a and is rotatably connected to the wall of the second groove 252. A second fixing member 21c is fixed to the first bracket 21a and covers the second groove 252. The second fixing member 21c is used to prevent the second rotation shaft 111b from falling out of the second groove 252. In other embodiments, the positions of the second rotation shaft 111b of the lens assembly 11 and the second groove 252 of the first bracket 21a can be reversed.

[0188] It is understandable that the second fixing member 21c can be fixed to the bottom surface of the first bracket 21a, or fixed in the second groove 252. In addition, the second fixing member 21c can cover the entire second groove 252, or can cover a portion of the second groove 252.

[0189] Exemplarily, the second fixing member 21c may be a metal sheet, such as a steel sheet or an aluminum sheet.

[0190] For example, the second fixing member 21c supports the second rotating shaft 111b. The second fixing member 21c can also realize three-point support with each side wall of the second groove 252. In this way, the connection stability between the second rotating shaft 111b and the first bracket 21a is better.

[0191] It is understandable that the first rotating shaft 111a is supported at three points by the first bracket 21a and the first fixing member 21b, and the second rotating shaft 111b is supported at three points by the first bracket 21a and the second fixing member 21c, thereby improving the connection stability between the camera body 1 and the first carrier 21.

[0192] As shown in Figure 13, the camera body 1 can be rotatably connected to the first bracket 21a via the first rotation shaft 111a and the second rotation shaft 111b. The first rotation shaft 111a and the second rotation shaft 111b can form a first rotation axis of the camera body 1. The camera body 1 can rotate relative to the first carrier 21 around the first rotation axis.

[0193] For example, since the first rotation axis 111 a and the second rotation axis 111 b are parallel to the X-axis direction, the camera body 1 can rotate around the X-axis direction in the YZ plane relative to the first carrier 21 .

[0194] FIG15 is a schematic structural diagram of an embodiment of the first driving mechanism 23 shown in FIG8 .

[0195] As shown in FIG. 15 , the first driving mechanism 23 includes a first shape memory alloy (SMA) wire 3 a , a second SMA wire 3 b , a first reed 4 a , a second reed 4 b , a third reed 4 c and a fourth reed 4 d .

[0196] It is understood that the first SMA wire 3a and the second SMA wire 3b are made of shape memory alloy (SMA) materials, such as nickel-titanium alloy. SMA is a general term for a class of metals with shape memory effect. The first reed 4a, the second reed 4b, the third reed 4c, and the fourth reed 4d can be structures that use their own deformation to generate relative displacement.

[0197] Figure 16 is a schematic structural diagram of an embodiment of the first reed 4a shown in Figure 15. Figure 17 is a schematic structural diagram of the first reed 4a shown in Figure 16 at another angle. Figure 18 is a schematic structural diagram of the first reed 4a shown in Figure 16 at yet another angle.

[0198] As shown in Figures 16 to 18, the first spring 4a includes a first fixed end 41a, a second fixed end 42a, and an electrical connection end 43a, wherein the electrical connection end 43a is located between the first fixed end 41a and the second fixed end 42a.

[0199] For example, in the Z-axis direction, there is a height difference between the electrical connection end 43a of the first spring 4a and the first fixed end 41a. It is understood that in the Z-axis direction, the first fixed end 41a can be located at the top of the electrical connection end 43a, or at the bottom of the electrical connection end 43a. Figures 16 to 18 illustrate that the first fixed end 41a can be located at the top of the electrical connection end 43a in the Z-axis direction.

[0200] For example, in the X-axis direction, the electrical connection end 43a is spaced apart from the first fixed end 41a. It is understood that in the X-axis direction, the first fixed end 41a can be located to the left of the electrical connection end 43a, or to the right of the electrical connection end 43a. Figures 16 to 18 illustrate that in the Z-axis direction, the first fixed end 41a can be located to the left of the electrical connection end 43a.

[0201] Exemplarily, in the Y-axis direction, there is a distance between the electrical connection end 43a and the first fixed end 41a. It can be understood that in the Y-axis direction, the first fixed end 41a can be located behind the electrical connection end 43a, or can be located in front of the electrical connection end 43a. FIGS. 16 to 18 illustrate that in the Y-axis direction, the first fixed end 41a can be located behind the electrical connection end 43a.

[0202] As shown in FIGS. 16 to 18, the first reed 4a includes a first section 44a, a second section 45a, and a third section 46a connected in sequence. In other words, the second section 45a of the first reed 4a is connected between the first section 44a and the third section 46a. Among them, the end of the first section 44a far from the second section 45a is the first fixed end 41a. The end of the third section 46a far from the second section 45a is the second fixed end 42a. At least a part of the second section 45a is the electrical connection end 43a.

[0203] Exemplarily, the first section 44a of the first reed 4a includes a first sub-section 441a and a second sub-section 442a connecting the first sub-section 441a. The first sub-section 441a of the first reed 4a is connected to the second section 45a of the first reed 4a.

[0204] Exemplarily, the first sub-section 441a of the first reed 4a is bent in the Y-axis direction relative to the second section 45a of the first reed 4a, and the angle a1 between the first sub-section 441a of the first reed 4a and the second section 45a of the first reed 4a satisfies: 90° < a1 < 180°. In this way, in the X-axis direction, there is a distance between the electrical connection end 43a and the first fixed end 41a. In the Y-axis direction, there is a distance between the electrical connection end 43a and the first fixed end 41a.

[0205] Exemplarily, the first sub-section 441a of the first reed 4a is bent in the Z-axis direction relative to the second sub-section 442a of the first reed 4a, and the angle b1 between the first sub-section 441a of the first reed 4a and the second sub-section 442a of the first reed 4a satisfies: 90° < b1 < 180°.

[0206] Exemplarily, the thickness of the first sub-section 441a of the first reed 4a is greater than the thickness of the second sub-section 442a of the first reed 4a.

[0207] Exemplarily, the third section 46a of the first reed 4a includes a fixed section 461a, a deformation section 462a, and a connection section 463a connected in sequence). In other words, the deformation section 462a of the first reed 4a is connected between the fixed section 461a and the connection section 463a. Among them, the connection section 463a of the first reed 4a is connected to the second section 45a of the first reed 4a.

[0208] For example, the first end of the fixed segment 461a of the first reed 4a is positioned opposite the first end of the connecting segment 463a of the first reed 4a. The second end of the fixed segment 461a of the first reed 4a is positioned opposite the second end of the connecting segment 463a of the first reed 4a. One end of the deformable segment 462a of the first reed 4a is connected to the second end of the fixed segment 461a of the first reed 4a, and the other end is connected to the first end of the connecting segment 463a of the first reed 4a. In this case, the third segment 46a of the first reed 4a is generally Z-shaped.

[0209] For example, the thickness of the deformation section 462a of the first reed 4a is smaller than the fixing section 461a and the connecting section 463a of the first reed 4a.

[0210] It is understood that the second reed 4b and the first reed 4a may have symmetrical or partially symmetrical structures, or different structures. In this embodiment, the second reed 4b and the first reed 4a are symmetrical structures. The basic design of the component structure of the second reed 4b, the connection relationship design between the components, and the connection relationship design between the components and other structures outside the assembly can all refer to the relevant solutions of the first reed 4a. At the same time, the second reed 4b and the first reed 4a can be slightly different in the detailed structure or position arrangement of the components.

[0211] It is understandable that the structures of the third reed 4c and the fourth reed 4d are similar to or identical to the structures of the first reed 4a and the second reed 4b, and details thereof will not be repeated here.

[0212] Fig. 19 is a partial structural diagram of an embodiment of the camera module 100 shown in Fig. 3. Fig. 20 is a partial cross-sectional diagram of an embodiment of the camera module 100 shown in Fig. 12 at DD.

[0213] As shown in Figure 19, the first fixed end 41a of the first reed 4a is fixed to the camera body 1. The electrical connection end 43a and the second fixed end 42a of the first reed 4a are both spaced apart from the camera body 1, that is, they are not in contact. The first fixed end 41b of the second reed 4b is fixed to the camera body 1. The electrical connection end 43b and the second fixed end 42b of the second reed 4b are both spaced apart from the camera body 1. The electrical connection end 43a of the first reed 4a and the electrical connection end 43b of the second reed 4b are arranged opposite to each other. The first fixed end 41a of the first reed 4a is located on the side of the electrical connection end 43a of the first reed 4a away from the second reed 4b. The first fixed end 41b of the second reed 4b is located on the side of the electrical connection end 43b of the second reed 4b away from the first reed 4a.

[0214] For example, the first fixed end 41a of the first reed 4a can be fixed to the first sub-side portion 1131 of the lens assembly 11. The second fixed end 42a and the electrical connection end 43a of the first reed 4a are both opposite to and spaced apart from the second sub-side portion 1132 of the lens assembly 11 of the camera subject 1. The first fixed end 41b of the second reed 4b can be fixed to the third sub-side portion 1133 of the lens assembly 11 of the camera subject 1. The second fixed end 42b and the electrical connection end 43b of the second reed 4b are both opposite to and spaced apart from the second sub-side portion 1132 of the lens assembly 11 of the camera subject 1.

[0215] As shown in Figure 19, the electrical connection end 43a of the first spring 4a is electrically connected to one end of the first SMA wire 3a. The electrical connection end 43b of the second spring 4b is electrically connected to the other end of the first SMA wire 3a. Thus, the first SMA wire 3a is electrically connected between the electrical connection end 43a of the first spring 4a and the electrical connection end 43b of the second spring 4b. For example, the first SMA wire 3a is parallel to the extension direction of the first rotation axis P1, i.e., the X-axis direction.

[0216] As shown in Figure 20, the second fixing end 42a of the first spring 4a is fixed to the first protrusion 255 of the first bracket 21a. The second fixing end 42b of the second spring 4b (see Figure 19) is fixed to the second protrusion 256 (see Figure 11) of the first bracket 21a.

[0217] As shown in Figures 19 and 20, when the first SMA wire 3a is energized, it contracts. On the one hand, the first end of the first SMA wire 3a applies a tensile force along the positive X-axis direction to the electrical connection end 43a of the first spring 4a (the direction of the tensile force is indicated by the bold arrow in Figure 19). The first fixed end 41a of the first spring 4a is subjected to a first force component along the positive X-axis direction and a second force component along the negative Z-axis direction (the direction of the tensile force is indicated by the bold arrow in Figure 19). On the other hand, the second end of the first SMA wire 3a applies a tensile force along the negative X-axis direction to the electrical connection end 43b of the second spring 4b (the direction of the tensile force is indicated by the bold arrow in Figure 19). The first fixed end 41b of the second spring 4b is subjected to a third force component along the negative X-axis direction and a fourth force component along the negative Z-axis direction (the direction of the tensile force is indicated by the bold arrow in Figure 19). The first and third force components can substantially cancel each other out. Under the action of the second force component and the fourth force component, the camera body 1 can rotate counterclockwise relative to the first carrier 21 via the first rotating shaft 111a (see FIG. 13 ) and the second rotating shaft 111b (see FIG. 13 ).

[0218] FIG21 is a schematic diagram of a partial structure of the camera module 100 shown in FIG19 at another angle.

[0219] As shown in Figure 21, the first fixed end 41c of the third spring 4c is fixed to the camera body 1. The electrical connection end 43c and the second fixed end 42c of the third spring 4c can be spaced apart from the camera body 1. The first fixed end 41d of the fourth spring 4d is fixed to the camera body 1. The electrical connection end 43d and the second fixed end 42d of the fourth spring 4d are spaced apart from the camera body 1. The electrical connection end 43c of the third spring 4c is arranged opposite to the electrical connection end 43d of the fourth spring 4d. The first fixed end 41c of the third spring 4c is located on the side of the electrical connection end 43c of the third spring 4c away from the fourth spring 4d. The first fixed end 41d of the fourth spring 4d is located on the side of the electrical connection end 43d of the fourth spring 4d away from the third spring 4c.

[0220] For example, the first fixed end 41c of the third spring 4c can be fixed to the fourth sub-side portion 1141 of the lens assembly 11. The second fixed end 42c and the electrical connection end 43c of the third spring 4c are both opposite to and spaced apart from the fifth sub-side portion 1142 of the lens assembly 11. The first fixed end 41d of the fourth spring 4d can be fixed to the sixth sub-side portion 1143 of the lens assembly 11. The second fixed end 42d and the electrical connection end 43d of the fourth spring 4d can both be opposite to and spaced apart from the fifth sub-side portion 1142 of the lens assembly 11.

[0221] As shown in Figure 21, the electrical connection end 43c of the third spring 4c is electrically connected to one end of the second SMA wire 3b. The electrical connection end 43d of the fourth spring 4d is electrically connected to the other end of the second SMA wire 3b. Thus, the second SMA wire 3b is electrically connected between the electrical connection end 43c of the third spring 4c and the electrical connection end 43d of the fourth spring 4d. For example, the second SMA wire 3b is parallel to the extension direction of the first rotation axis P1, i.e., the X-axis direction.

[0222] As shown in Figure 20, the second fixing end 42c of the third spring 4c is fixed to the third protrusion 257 of the first bracket 21a. The second fixing end 42d of the fourth spring 4d is fixed to the fourth protrusion 258 of the first bracket 21a (see Figure 10).

[0223] As shown in Figures 20 and 21, when the second SMA wire 3b is energized, it contracts. On the one hand, the first end of the second SMA wire 3b applies a tensile force along the negative X-axis direction to the electrical connection end 43c of the third spring 4c (the direction of the tensile force is indicated by a thick arrow in Figure 21). The first fixed end 41c of the third spring 4c is subjected to a fifth force component along the negative X-axis direction and a sixth force component along the negative Z-axis direction (the directions of the tensile forces are indicated by thick arrows in Figure 21). On the other hand, the second end of the second SMA wire 3b applies a tensile force along the positive X-axis direction to the electrical connection end 43d of the fourth spring 4d (the directions of the tensile forces are indicated by thick arrows in Figure 21). The first fixed end 41d of the fourth spring 4d is subjected to a seventh force component along the positive X-axis direction and an eighth force component along the negative Z-axis direction (the directions of the tensile forces are indicated by thick arrows in Figure 21). The fifth and seventh force components can substantially cancel each other out. Under the action of the sixth force component and the eighth force component, the camera body 1 can rotate clockwise relative to the first carrier 21 via the first rotation shaft 111 a and the second rotation shaft 111 b .

[0224] The following describes a specific embodiment of controlling the camera body 1 to rotate relative to the first carrier 21 via the first rotating shaft 111 a and the second rotating shaft 111 b with reference to the relevant drawings.

[0225] As shown in Figures 19 to 21, in one embodiment, when the first and second SMA wires 3a and 3b are simultaneously energized to their maximum current, the first and second SMA wires 3a and 3b contract. On one hand, the first end of the first SMA wire 3a applies a tensile force in the positive X-axis direction to the electrical connection end 43a of the first spring 4a. The first fixed end 41a of the first spring 4a is subjected to a first force component in the positive X-axis direction and a second force component in the negative Z-axis direction. On the other hand, the second end of the first SMA wire 3a applies a tensile force in the negative X-axis direction to the electrical connection end 43b of the second spring 4b. The first fixed end 41b of the second spring 4b is subjected to a third force component in the negative X-axis direction and a fourth force component in the negative Z-axis direction. Furthermore, the first end of the second SMA wire 3b applies a tensile force in the negative X-axis direction to the electrical connection end 43c of the third spring 4c. The first fixed end 41c of the third spring 4c is subjected to a fifth force component in the negative X-axis direction and a sixth force component in the negative Z-axis direction. On the other hand, the second end of the second SMA wire 3b applies a tensile force along the positive X-axis direction to the electrical connection end 43d of the fourth spring 4d. The first fixed end 41d of the fourth spring 4d is subjected to a seventh force component along the positive X-axis direction and an eighth force component along the negative Z-axis direction. The first and third force components can approximately cancel each other out. The fifth and seventh force components can approximately cancel each other out. Furthermore, the combined force of the second and fourth force components can approximately cancel each other out with the combined force of the sixth and eighth force components. At this point, the camera subject 1 is in a balanced state.

[0226] When the current flowing through the first SMA wire 3a is controlled to be greater than the current flowing through the second SMA wire 3b (i.e., the current flowing through the second SMA wire 3b is reduced), the resultant force of the second and fourth force components is greater than the resultant force of the sixth and eighth force components. At this point, the camera body 1 can rotate clockwise relative to the first carrier 21 via the first and second rotating shafts 111a, 111b.

[0227] When the current flowing through the first SMA wire 3a is controlled to be smaller than the current flowing through the second SMA wire 3b (i.e., the current flowing through the first SMA wire 3a is reduced), the resultant force of the sixth and eighth force components is greater than the resultant force of the second and fourth force components. At this point, the camera body 1 can rotate counterclockwise relative to the first carrier 21 via the first and second rotating shafts 111a, 111b.

[0228] Exemplarily, the angle at which the camera subject 1 rotates relative to the first carrier 21 around the first rotation axis is greater than 0.8°.

[0229] Exemplarily, the angle at which the camera subject 1 rotates relative to the first carrier 21 around the first rotation axis is in a range of 1° to 4°.

[0230] The following describes simulation data of the camera body 1 rotating relative to the first carrier 21 via the first rotating shaft 111 a and the second rotating shaft 111 b .

[0231] In one embodiment, the length of the first SMA wire 3a is 10 millimeters (mm). When the first SMA wire 3a contracts by 100 micrometers, the first fixed end 41a of the first spring 4a can descend by 370 micrometers along the Z-axis. Thus, the first spring 4a can amplify the contracted distance of the first SMA wire 3a by 3.7 times, i.e., the amplification factor of the first spring 4a is 3.7. At this point, the camera subject 1 can rotate 3° relative to the first carrier 21 via the first and second rotating shafts 111a, 111b, pulled by the first spring 4a.

[0232] It is understood that the magnification of the first spring 4a is related to the rotation effect of the camera subject 1. Generally, if the magnification of the first spring 4a is large, the camera subject 1 is likely to become unstable during rotation, and the anti-shake accuracy is poor. If the magnification of the first spring 4a is small, the rotation angle of the camera subject 1 is small, and the anti-shake effect is poor. In this embodiment, by adjusting the thickness of each segment of the first spring 4a, the shape of each segment, and the bending angle of each segment, a first spring 4a capable of achieving an appropriate magnification is provided. This ensures that the camera subject 1 is stable during rotation, with better anti-shake accuracy, while also ensuring that the rotation angle of the camera subject 1 is not small, and the anti-shake effect is better.

[0233] Exemplarily, the magnification factor of the first reed 4a is in the range of 4 to 5.

[0234] Similarly, the structural settings of the second reed 4b, the third reed 4c, and the fourth reed 4d are similar to those of the first reed 4a. Specifically, it will not be elaborated here.

[0235] It can be understood that by setting the first sub-segment 441a of the first reed 4a to be bent along the Y-axis direction relative to the second segment 45a of the first reed 4a, and the angle a1 between the first sub-segment 441a and the second segment 45a of the first reed 4a satisfies: 90° < a1 < 180°, this can ensure that the rotation angle of the imaging body 1 remains unchanged while reducing the distance that the first fixed end 41a of the first reed 4a moves along the Z-axis direction, thereby reducing the power consumption of the first SMA wire 3a.

[0236] Similarly, the structural settings of the second reed 4b, the third reed 4c, and the fourth reed 4d are similar to those of the first reed 4a. Specifically, it will not be elaborated here.

[0237] The following introduces an implementation manner of the assembly steps of the imaging body 1, the first carrier 21, and the first driving mechanism 23.

[0238] As shown in FIGS. 9 to 11, invert the first carrier 21, that is, face the bottom surface of the first carrier 21. At this time, the openings formed by the first groove 251 and the second groove 252 on the bottom surface of the first carrier 21 can face the operator.

[0239] As shown in FIGS. 19 and 21, fix the first fixed ends 41a of the first reed 4a, the first fixed ends 41b of the second reed 4b, the first fixed ends 41c of the third reed 4c, and the first fixed ends 41d of the fourth reed 4d at different positions of the imaging body 1 respectively, and the electrical connection ends 43a of the first reed 4a and the electrical connection ends 43b of the second reed 4b are arranged opposite to each other. The first fixed end 41a of the first reed 4a is located on the side of the electrical connection end 43a of the first reed 4a away from the second reed 4b. The first fixed end 41b of the second reed 4b is located on the side of the electrical connection end 43b of the second reed 4b away from the first reed 4a. The electrical connection ends 43b of the third reed 4c and the electrical connection ends 43d of the fourth reed 4d are arranged opposite to each other. The first fixed end 41c of the third reed 4c is located on the side of the electrical connection end 43c of the third reed 4c away from the fourth reed 4d. The first fixed end 41d of the fourth reed 4d is located on the side of the electrical connection end 43d of the fourth reed 4d away from the third reed 4c.

[0240] As shown in Figures 19 and 21, the first SMA wire 3a is electrically connected between the electrical connection end 43a of the first spring 4a and the electrical connection end 43b of the second spring 4b, and the second SMA wire 3b is electrically connected between the electrical connection end 43c of the third spring 4c and the electrical connection end 43d of the fourth spring 4d.

[0241] As shown in FIG12 and FIG13 , the camera body 1 is turned upside down, the first rotation shaft 111 a of the camera body 1 is aligned with the first groove 251 and assembled into the first groove 251 , and the second rotation shaft 111 b is aligned with the second groove 252 and assembled into the second groove 252 .

[0242] The first fixing member 21b is fixed to the first bracket 21a and covers the first groove 251. The first bracket 21a and the first fixing member 21b support the first rotating shaft 111a. For example, the first fixing member 21b can be fixed to the first bracket 21a by a dispensing process.

[0243] The second fixing member 21c is fixed to the first bracket 21a and covers the second groove 252. The first bracket 21a and the second fixing member 21c support the second rotating shaft 111b. For example, the second fixing member 21c can be fixed to the first bracket 21a by a dispensing process.

[0244] As shown in FIG20 , the second fixed end 42a of the first reed 4a, the second fixed end 42b of the second reed 4b, the second fixed end 42c of the third reed 4c and the second fixed end 42d of the fourth reed 4d are fixed at different positions of the camera body 1 respectively.

[0245] Figure 22 is a partially exploded schematic diagram of an embodiment of the second carrier 22 shown in Figure 8. Figure 23 is a schematic structural diagram of the second carrier 22 shown in Figure 22 at another angle.

[0246] As shown in FIG. 22 and FIG. 23 , the second carrier 22 includes a second bracket 22 a , a third fixing member 22 b and a fourth fixing member 22 c .

[0247] Exemplarily, the second bracket 22a includes a first side portion 221 and a second side portion 222, and a third side portion 223 and a fourth side portion 224. The third side portion 223 and the fourth side portion 224 of the second bracket 22a are connected between the first side portion 221 and the second side portion 222 of the second bracket 22a.

[0248] Exemplarily, the third side 223 of the second bracket 22a includes a first sub-side 2231, a second sub-side 2232 and a third sub-side 2233 connected in sequence, the first sub-side 2231 is connected to the first side 221 of the second bracket 22a, and the third sub-side 2233 is connected to the second side 222 of the second bracket 22a.

[0249] For example, the angle between the first sub-side 2131 of the second carrier 22 and the second sub-side 2132 of the second carrier 22, and the angle between the second sub-side 2132 of the second carrier 22 and the third sub-side 2133 of the second carrier 22 are both obtuse angles.

[0250] Illustratively, the fourth side 224 of the second bracket 22a includes a fourth sub-side 2241 , a fifth sub-side 2242 and a sixth sub-side 2243 connected in sequence. The fourth sub-side 2241 is connected to the second side 222 , and the sixth sub-side 2243 is connected to the first side 221 .

[0251] Exemplarily, the included angle between the fourth sub-side 2241 and the fifth sub-side 2242 , and the included angle between the fifth sub-side 2242 and the sixth sub-side 2243 are obtuse angles.

[0252] Exemplarily, the cross-section of the second bracket 22 a parallel to the XY plane is substantially octagonal.

[0253] It is understood that the second bracket 22a may include fewer or more structures. For example, the cross-section of the second bracket 22a parallel to the XY plane may be a quadrilateral, pentagon, hexagon, or heptagon. When the second bracket 22a includes more structures, the second bracket 22a may include more sides. In this case, the cross-section of the second bracket 22a parallel to the XY plane may be an n-gon, where n is greater than 8.

[0254] For example, the angle between two adjacent sides is 135°. In this case, the second bracket 22a is substantially in the shape of a regular octagon.

[0255] As shown in FIG. 22 and FIG. 23 , the second bracket 22 a defines a third groove 271 and a fourth groove 272 that are oppositely disposed.

[0256] Exemplarily, the third groove 271 is located at the second sub-side portion 2232 of the second bracket 22a, and the fourth groove 272 is located at the fifth sub-side portion 2242 of the second bracket 22a.

[0257] It is understandable that the third groove 271 and the fourth groove 272 may be similar or identical to the first groove 251 and the second groove 252 of the first carrier 21 (see FIG. 9 to FIG. 11 ), and details thereof will not be repeated here.

[0258] As shown in Figures 22 and 23, the second bracket 22a is further provided with a first protrusion 275 and a second protrusion 276. The first protrusion 275 and the second protrusion 276 are protruded from the inner surface of the second bracket 22a.

[0259] Exemplarily, the first protrusion 275 and the second protrusion 276 are protruded from the inner surface of the first side portion 221 of the second bracket 22 a.

[0260] It is understandable that, although FIG. 22 and FIG. 23 illustrate that the first bump 275 and the second bump 276 are spaced apart from each other, the first bump 275 may also be connected to the second bump 276 , in which case the first bump 275 and the second bump 276 form one bump.

[0261] As shown in Figures 22 and 23, the second bracket 22a is further provided with a third protrusion 277 and a fourth protrusion 278. The third protrusion 277 and the fourth protrusion 278 are protruded from the inner surface of the second bracket 22a.

[0262] Exemplarily, the third protrusion 277 and the fourth protrusion 278 may be protruded from the inner surface of the second side portion 222 .

[0263] It is understandable that, although FIG. 22 and FIG. 23 illustrate that the third bump 277 and the fourth bump 278 are spaced apart, the third bump 277 may also be connected to the fourth bump 278 , in which case the third bump 277 and the fourth bump 278 form one bump.

[0264] FIG24 is a schematic diagram of a partial structure of the camera module 100 shown in FIG3 in one embodiment.

[0265] As shown in Figure 24, the first bracket 21a is located inside the second bracket 22a, that is, the second bracket 22a is arranged around the first bracket 21a. In this way, the first carrier 21 is also located inside the second carrier 22, that is, the second carrier 22 can also be arranged around the first carrier 21.

[0266] Illustratively, the first side 211 of the first bracket 21a is opposite to and spaced from the first side 221 of the second bracket 22a. The second side 212 of the first bracket 21a is opposite to and spaced from the second side 222 of the second bracket 22a. The first sub-side 2131 of the first bracket 21a is opposite to and spaced from the first sub-side 2231 of the second bracket 22a. The second sub-side 2132 of the first bracket 21a is opposite to and spaced from the second sub-side 2232 of the second bracket 22a. The third sub-side 2133 of the first bracket 21a is opposite to and spaced from the third sub-side 2233 of the second bracket 22a. The fourth sub-side 2141 of the first bracket 21a is opposite to and spaced from the fourth sub-side 2241 of the second bracket 22a. The fifth sub-side 2142 of the first bracket 21a is opposite to and spaced from the fifth sub-side 2242 of the second bracket 22a. The sixth sub-side portion 2143 of the first bracket 21 a and the sixth sub-side portion 2243 of the second bracket 22 a are opposite to each other and spaced apart.

[0267] FIG25 is a partial cross-sectional view of an embodiment of the camera module 100 shown in FIG24 taken along line EE.

[0268] As shown in Figure 25 , at least a portion of the third rotating shaft 259a of the first bracket 21a is located within the third groove 271 of the second bracket 22a and is rotatably connected to the wall of the third groove 271. The third fixing member 22b is fixed to the second bracket 22a and covers the third groove 271. The third fixing member 22b is used to prevent the third rotating shaft 259a from falling out of the third groove 271.

[0269] It is understandable that the third fixing member 22b can be fixed to the bottom surface of the second bracket 22a, or fixed in the third groove 271. In addition, the third fixing member 22b can cover the entire third groove 271, or can cover part of the third groove 271.

[0270] Exemplarily, the third fixing member 22b may be a metal sheet, such as a steel sheet or an aluminum sheet.

[0271] For example, the third fixing member 22b supports the third rotating shaft 259a. The third fixing member 22b can cooperate with the side walls of the third groove 271 to achieve three-point support for the third rotating shaft 259a. In this way, the connection stability between the third rotating shaft 259a and the second bracket 22a is improved.

[0272] In other embodiments, the positions of the third rotating shaft 259a of the first bracket 21a and the third groove 271 of the second bracket 22a can be swapped.

[0273] As shown in Figure 25 , at least a portion of the fourth rotating shaft 259b of the first bracket 21a is located within the fourth groove 272 of the second bracket 22a and is rotatably connected to the wall of the fourth groove 272. A fourth fixing member 22c is fixed to the second bracket 22a and covers the fourth groove 272. The fourth fixing member 22c is used to prevent the fourth rotating shaft 259b from falling out of the fourth groove 272. In other embodiments, the positions of the fourth rotating shaft 259b of the first bracket 21a and the fourth groove 272 of the second bracket 22a can be reversed.

[0274] It is understandable that the fourth fixing member 22c can be fixed to the bottom surface of the second bracket 22a, or fixed in the fourth groove 272. In addition, the fourth fixing member 22c can cover the entire fourth groove 272, or can cover a portion of the fourth groove 272.

[0275] Exemplarily, the fourth fixing member 22c may be a metal sheet, such as a steel sheet or an aluminum sheet.

[0276] For example, the fourth fixing member 22c supports the fourth rotating shaft 259b. The fourth fixing member 22c can also realize three-point support with each groove sidewall of the fourth groove 272. In this way, the connection stability of the fourth rotating shaft 259b and the second bracket 22a is better.

[0277] It is understandable that the third rotating shaft 259a is supported at three points by the second bracket 22a and the third fixing member 22b, and the fourth rotating shaft 259b is supported at three points by the second bracket 22a and the fourth fixing member 22c, thereby improving the connection stability between the first carrier 21 and the second carrier 22.

[0278] It is understood that the camera body 1 and the first carrier 21 can be rotatably connected to the second carrier 22 via the third rotation axis 259a and the fourth rotation axis 259b. The third rotation axis 259a and the fourth rotation axis 259b can form a second rotation axis of the camera body 1. The camera body 1 and the first carrier 21 can rotate relative to the second carrier 22 around the second rotation axis.

[0279] For example, since the third rotation axis 259 a and the fourth rotation axis 259 b are parallel to the Y-axis direction, the camera body 1 and the first carrier 21 can rotate relative to the second carrier 22 around the Y-axis direction on the XZ plane.

[0280] FIG26 is a schematic structural diagram of an embodiment of the second driving mechanism 24 shown in FIG8 .

[0281] As shown in FIG. 26 , the second driving mechanism 24 includes a third SMA wire 5 a , a fourth SMA wire 5 b , a fifth reed 6 a , a sixth reed 6 b , a seventh reed 6 c and an eighth reed 6 d .

[0282] It is understood that the third SMA wire 5a, the fourth SMA wire 5b, the fifth spring 6a, the sixth spring 6b, the seventh spring 6c, and the eighth spring 6d of the second drive mechanism 24 are respectively configured the same as or similar to the first SMA wire 3a, the second SMA wire 3b, the first spring 4a, the second spring 4b, the third spring 4c, and the fourth spring 4d of the first drive mechanism 23. Detailed description is omitted here.

[0283] FIG27 is a schematic diagram of a partial structure of the camera module 100 shown in FIG3 in one embodiment.

[0284] As shown in Figure 27, the first fixed end 61a of the fifth spring 6a is fixed to the first bracket 21a. The electrical connection end 63a and the second fixed end 62a of the fifth spring 6a are both spaced apart from the first bracket 21a, that is, they are not in contact. The first fixed end 61b of the sixth spring 6b is fixed to the first bracket 21a. The electrical connection end 63b and the second fixed end 62b of the sixth spring 6b are both spaced apart from the first bracket 21a. The electrical connection end 63a of the fifth spring 6a and the electrical connection end 63b of the sixth spring 6b are arranged opposite each other. The first fixed end 61a of the fifth spring 6a is located on the side of the electrical connection end 63a of the fifth spring 6a away from the sixth spring 6b. The first fixed end 61b of the sixth spring 6b is located on the side of the electrical connection end 63b of the sixth spring 6b away from the fifth spring 6a.

[0285] For example, the first fixed end 61a of the fifth spring piece 6a can be fixed to the sixth sub-side 2143 of the first bracket 21a. The second fixed end 62a and the electrical connection end 43a of the fifth spring piece 6a are both opposite to and spaced apart from the first side 211 of the first bracket 21a. The first fixed end 61b of the sixth spring piece 6b can be fixed to the first sub-side 2131 of the first bracket 21a. The second fixed end 62b and the electrical connection end 63b of the sixth spring piece 6b are both opposite to and spaced apart from the first side 211 of the first bracket 21a.

[0286] As shown in Figure 27, the electrical connection end 63a of the fifth spring 6a is electrically connected to one end of the third SMA wire 5a. The electrical connection end 63b of the sixth spring 6b is electrically connected to the other end of the third SMA wire 5a. Thus, the third SMA wire 5a is electrically connected between the electrical connection end 63a of the fifth spring 6a and the electrical connection end 63b of the sixth spring 6b. For example, the third SMA wire 5a is parallel to the extension direction of the second rotation axis P2, i.e., the Y-axis direction.

[0287] FIG28 is a partial cross-sectional view of an embodiment of the camera module 100 shown in FIG27 taken along line FF.

[0288] As shown in Figure 28, the second fixed end 62a of the fifth spring 6a is fixed to the first protrusion 275 of the second bracket 22a. The second fixed end 62b of the sixth spring 6b (see Figure 27) is fixed to the second protrusion 276 (see Figure 23) of the second bracket 22a.

[0289] As shown in Figures 27 and 28, when the third SMA wire 5a is energized, it contracts. On the one hand, the first end of the third SMA wire 5a applies a tensile force along the positive Y-axis direction to the electrical connection end 63a of the fifth spring 6a. The first fixed end 61a of the fifth spring 6a is subjected to a first force component along the positive X-axis direction and a second force component along the negative Z-axis direction. On the other hand, the second end of the third SMA wire 5a applies a tensile force along the negative Y-axis direction to the electrical connection end 63b of the sixth spring 6b. The first fixed end 61b of the sixth spring 6b is subjected to a third force component along the negative X-axis direction and a fourth force component along the negative Z-axis direction. The first and third force components can substantially cancel each other out. Under the action of the second and fourth force components, the camera body 1 can rotate counterclockwise relative to the second carrier 22 via the third and fourth rotation axes 259a (see Figure 25) and 259b (see Figure 25).

[0290] FIG29 is a schematic diagram of a partial structure of the camera module 100 shown in FIG27 at another angle.

[0291] As shown in Figure 29, the first fixed end 61c of the seventh spring 6c is fixed to the first bracket 21a. The electrical connection end 63c and the second fixed end 62c of the seventh spring 6c are both spaced apart from the first bracket 21a. The first fixed end 61d of the eighth spring 6d is fixed to the first bracket 21a. The electrical connection end 63d and the second fixed end 62d of the eighth spring 6d are both spaced apart from the first bracket 21a. The electrical connection end 63c of the seventh spring 6c is positioned opposite the electrical connection end 63d of the eighth spring 6d. The first fixed end 61c of the seventh spring 6c is located on the side of the electrical connection end 63c of the seventh spring 6c that is away from the eighth spring 6d. The first fixed end 61d of the eighth spring 6d is located on the side of the electrical connection end 63d of the eighth spring 6d that is away from the seventh spring 6c.

[0292] For example, the first fixed end 61c of the seventh spring piece 6c can be fixed to the third sub-side 2133 of the first bracket 21a. The second fixed end 62c and the electrical connection end 63c of the seventh spring piece 6c are both opposite to and spaced apart from the second side 212 of the first bracket 21a. The first fixed end 61d of the eighth spring piece 6d can be fixed to the fourth sub-side 2141 of the first bracket 21a. The second fixed end 62d and the electrical connection end 63d of the eighth spring piece 6d are both opposite to and spaced apart from the second side 212 of the first bracket 21a.

[0293] As shown in Figure 29, the electrical connection end 63c of the seventh spring 6c is electrically connected to one end of the fourth SMA wire 5b. The electrical connection end 63d of the eighth spring 6d is electrically connected to the other end of the fourth SMA wire 5b. Thus, the fourth SMA wire 5b is electrically connected between the electrical connection end 63c of the seventh spring 6c and the electrical connection end 63d of the eighth spring 6d. For example, the fourth SMA wire 5b is parallel to the extension direction of the second rotation axis P2, i.e., the Y-axis direction.

[0294] As shown in Figure 28, the second fixed end 62c of the seventh spring piece 6c is fixed to the third protrusion 277 of the second bracket 22a. The second fixed end 62d of the eighth spring piece 6d is fixed to the fourth protrusion 278 of the second bracket 22a.

[0295] As shown in Figure 29, when the fourth SMA wire 5b is energized, it contracts. On the one hand, the first end of the fourth SMA wire 5b applies a tensile force along the negative Y-axis direction to the electrical connection end 63c of the seventh spring 6c. The first fixed end 61c of the seventh spring 6c is subjected to a fifth force component along the negative Y-axis direction and a sixth force component along the negative Z-axis direction. On the other hand, the second end of the fourth SMA wire 5b applies a tensile force along the positive Y-axis direction to the electrical connection end 63d of the eighth spring 6d. The first fixed end 61d of the eighth spring 6d is subjected to a seventh force component along the positive Y-axis direction and an eighth force component along the negative Z-axis direction. The fifth and seventh force components can substantially cancel each other out. Under the action of the sixth and eighth force components, the camera body 1 can rotate clockwise relative to the second carrier 22 via the third rotating shaft 259a (see Figure 25) and the fourth rotating shaft 259b (see Figure 25).

[0296] The following describes a specific embodiment of controlling the camera body 1 to rotate relative to the second carrier 22 via the third rotating shaft 259a (see FIG. 25 ) and the fourth rotating shaft 259b (see FIG. 25 ) in conjunction with the relevant drawings.

[0297] In one embodiment, the third and fourth SMA wires 5a, 5b are simultaneously energized to their maximum current, causing them to contract. On one hand, the first end of the third SMA wire 5a applies a tensile force in the positive Y-axis direction to the electrical connection end 63a of the fifth spring piece 6a. The first fixed end 61a of the fifth spring piece 6a is subjected to a first force component in the positive Y-axis direction and a second force component in the negative Z-axis direction. On the other hand, the second end of the third SMA wire 5a applies a tensile force in the negative Y-axis direction to the electrical connection end 63b of the sixth spring piece 6b. The first fixed end 61b of the sixth spring piece 6b is subjected to a third force component in the negative Y-axis direction and a fourth force component in the negative Z-axis direction. Furthermore, the first end of the fourth SMA wire 5b applies a tensile force in the negative Y-axis direction to the electrical connection end 63c of the seventh spring piece 6c. The first fixed end 61c of the seventh spring piece 6c is subjected to a fifth force component in the negative Y-axis direction and a sixth force component in the negative Z-axis direction. On the other hand, the second end of the fourth SMA wire 5b applies a tensile force along the positive Y-axis direction to the electrical connection end 63d of the eighth spring 6d. The first fixed end 61d of the eighth spring 6d is subjected to a seventh force component along the positive Y-axis direction and an eighth force component along the negative Z-axis direction. The first and third force components can substantially cancel each other out. The fifth and seventh force components can substantially cancel each other out. Furthermore, the combined force of the second and fourth force components can substantially cancel each other out with the combined force of the sixth and eighth force components. At this point, the camera subject 1 is in a balanced state.

[0298] When the current flowing through the third SMA wire 5a is controlled to be greater than the current flowing through the fourth SMA wire 5b (i.e., the current flowing through the fourth SMA wire 5b is reduced), the resultant force of the second and fourth force components is greater than the resultant force of the sixth and eighth force components. At this point, the camera body 1 can rotate clockwise relative to the second carrier 22 via the third and fourth rotation shafts 259a (see FIG. 25 ) and 259b (see FIG. 25 ).

[0299] When the current flowing through the third SMA wire 5a is controlled to be smaller than the current flowing through the fourth SMA wire 5b (i.e., the current flowing through the third SMA wire 5a is reduced), the combined force of the sixth and eighth force components is greater than the combined force of the second and fourth force components. At this point, the camera body 1 can rotate counterclockwise relative to the second carrier 22 via the third rotating shaft 259a (see FIG. 25 ) and the fourth rotating shaft 259b (see FIG. 25 ).

[0300] Exemplarily, the first carrier 21 drives the camera body 1 to rotate relative to the second carrier 22 around the second rotation axis within a range of an angle greater than 0.8°.

[0301] Exemplarily, the first carrier 21 drives the camera body 1 to rotate relative to the second carrier 22 around the second rotation axis to an angle in the range of 1° to 4°.

[0302] It will be appreciated that, as mentioned above, by adjusting the thickness, shape, and bending angle of each segment of the first spring 4a, a first spring 4a capable of achieving an appropriate magnification factor is provided. This ensures both stability during rotation of the camera subject 1, achieving excellent anti-shake accuracy, and ensuring that the rotation angle of the camera subject 1 is not reduced, achieving excellent anti-shake effectiveness. Similarly, the structures of the fifth spring 6a, sixth spring 6b, seventh spring 6c, and eighth spring 6d are similar to those of the first spring 4a. The details will not be repeated here.

[0303] It will be appreciated that the various embodiments described above describe the pan-tilt module 2 driving the lens assembly 11 to rotate relative to the first carrier 21 about the first rotation axis P1, and the first carrier 21 driving the lens assembly 11 to rotate relative to the second carrier 22 about the second rotation axis P2. In other embodiments, the pan-tilt module 2 may also drive the image sensor assembly 12 to rotate relative to the first carrier 21 about the first rotation axis P1, and the first carrier 21 may drive the image sensor assembly 12 to rotate relative to the second carrier 22 about the second rotation axis P2. The arrangement between the image sensor assembly 12 and the first carrier 21 can be similar to the arrangement between the lens assembly 11 and the first carrier 21. The details will not be repeated here.

[0304] It will be appreciated that the above description of the pan / tilt module 2 specifically describes the pan / tilt module 2 through the relevant drawings. A first carrier 21 is disposed around the camera body 1, and the camera body 1 rotates relative to the first carrier 21 about a first rotation axis P1. A second carrier 22 is disposed around the first carrier 21, and the first carrier 21 drives the camera body 1 to rotate relative to the second carrier 22 about a second rotation axis P2. In this case, the camera body 1, the first carrier 21, and the second carrier 22 are generally arranged in a nested manner.

[0305] It can be understood that the first carrier 21 of this embodiment has a "multi-purpose" function. On the one hand, the first carrier 21 can cooperate with the second carrier 22 to serve as a stator for rotating the camera body 1 around the first rotation axis P1. On the other hand, the first carrier 21 can serve as a mover for rotating the camera body 1 around the second rotation axis P2. In this way, the first carrier 21 can play a role in structural reuse, thereby simplifying the structure of the pan-tilt module 2 and achieving a miniaturized design of the pan-tilt module 2.

[0306] In addition, the second carrier 22 of this embodiment also has the function of "one thing for multiple uses". The second carrier 22 can cooperate with the first carrier 21 to serve as a stator for the camera body 1 to rotate around the first rotation axis P1. On the other hand, the second carrier 22 can serve as a stator for the camera body 1 to rotate around the second rotation axis P2. In this way, the second carrier 22 can serve as a stator of a component of the camera module 100. In addition, the second carrier 22 can be arranged around the first carrier 21, and the second carrier 22 has the function of protecting the first carrier 21, the first drive mechanism 23 and the second drive mechanism 24 of the pan-tilt module 2. In this way, the second carrier 22 can play a role of structural reuse, thereby simplifying the structure of the pan-tilt module 2, thereby realizing the miniaturization of the pan-tilt module 2.

[0307] It can be understood that the second carrier 22 can serve as a stator of a component of the camera module 100, and can also protect the first carrier 21, the first drive mechanism 23 and the second drive mechanism 24 of the pan-tilt module 2. In this way, when the camera module 100 is applied to the electronic device 1000, the second carrier 22 of the pan-tilt module 2 can be directly fixed on the structural member (such as the shell or the middle frame) of the electronic device 1000. In this way, compared with the traditional camera module solution: a shell needs to be provided on the outside of the pan-tilt module of the camera module, and the camera module is packaged and fixed to the structural member (such as the shell or the middle frame) of the electronic device 1000 through the shell. In this embodiment, since the second carrier 22 of the pan-tilt module 2 can be directly fixed on the structural member (such as the shell or the middle frame) of the electronic device 1000, the camera module 100 does not need to be additionally provided with a shell, thereby further simplifying the structure of the camera module 100, which is conducive to the miniaturization of the camera module 100. In addition, the step of fixing the camera module 100 to a structural member (such as a housing or a middle frame) of the electronic device 1000 through the housing can be omitted, thereby reducing cost investment.

[0308] In this embodiment, by arranging the mutual cooperation between the first rotating shaft 111a of the lens assembly 11 and the first groove 251 of the first bracket 21a, and the mutual cooperation between the second rotating shaft 111b of the lens assembly 11 and the second groove 252 of the first bracket 21a, on the one hand, the camera subject 1 can be allowed to rotate relative to the first carrier 21 through the first rotating shaft 111a and the second rotating shaft 111b, and on the other hand, the rotation of the camera subject 1 in other directions can be restricted, thereby limiting the freedom of rotation of the camera subject 1 around the first rotation axis P1, so that the anti-shake of the camera subject 1 is more stable and the anti-shake effect is better.

[0309] In this embodiment, by setting the mutual cooperation between the third rotating shaft 259a of the first carrier 21 and the third groove 271 of the second carrier 22, and the mutual cooperation between the fourth rotating shaft 259b of the first carrier 21 and the fourth groove 272 of the second carrier 22, on the one hand, the camera subject 1 can be rotated relative to the second carrier 22 through the third rotating shaft 259a and the fourth rotating shaft 259b, and on the other hand, the rotation of the camera subject 1 in other directions can be restricted, thereby limiting the freedom of rotation of the camera subject 1 around the second rotation axis P2, so that the anti-shake of the camera subject 1 is more stable and the anti-shake effect is better.

[0310] An embodiment of the assembly steps of the first carrier 21 , the second carrier 22 , and the second driving mechanism 24 is described below.

[0311] As shown in Figures 22 and 23, the second carrier 22 is turned upside down, that is, the bottom surface of the second carrier 22 faces. At this time, the openings formed by the third groove 271 and the fourth groove 272 on the bottom surface of the second carrier 22 can face the operator.

[0312] As shown in Figures 27 and 29, the first fixed end 61a of the fifth spring 6a, the first fixed end 61b of the sixth spring 6b, the first fixed end 61c of the seventh spring 6c, and the first fixed end 61d of the eighth spring 6d are fixed to different positions on the first carrier 21, with the electrical connection end 63a of the fifth spring 6a and the electrical connection end 63b of the sixth spring 6b positioned opposite each other. The first fixed end 61a of the fifth spring 6a is located on the side of the electrical connection end 63a of the fifth spring 6a away from the sixth spring 6b. The first fixed end 61b of the sixth spring 6b is located on the side of the electrical connection end 63b of the sixth spring 6b away from the fifth spring 6a. The electrical connection end 63c of the seventh spring 6c is positioned opposite the electrical connection end 63d of the eighth spring 6d. The first fixed end 61c of the seventh spring 6c is located on the side of the electrical connection end 63c of the seventh spring 6c away from the eighth spring 6d. The first fixed end 61d of the eighth reed 6d is located on a side of the electrical connection end 63d of the eighth reed 6d away from the seventh reed 6c.

[0313] As shown in Figures 27 and 29, the third SMA wire 5a is electrically connected between the electrical connection end 63a of the fifth spring 6a and the electrical connection end 63b of the sixth spring 6b, and the fourth SMA wire 5b is electrically connected between the electrical connection end 63c of the seventh spring 6c and the electrical connection end 63a of the eighth spring 6d.

[0314] As shown in Figure 25, the structure assembled with the camera body 1 and the first carrier 21 is inverted, the third rotating shaft 259a of the first carrier 21 is aligned with the third groove 271 and assembled into the third groove 271, and the fourth rotating shaft 259b is aligned with the fourth groove 272 and assembled into the fourth groove 272.

[0315] The third fixing member 22b is fixed to the second bracket 22a and covers the third groove 271. The second bracket 22a and the third fixing member 22b support the third rotating shaft 259a. For example, the third fixing member 22b can be fixed to the second bracket 22a by a dispensing process.

[0316] The fourth fixing member 22c is fixed to the second bracket 22a and covers the fourth groove 272. The second bracket 22a and the fourth fixing member 22c support the fourth rotating shaft 259b. For example, the fourth fixing member 22c can be fixed to the second bracket 22a by a dispensing process.

[0317] The second fixing ends 62 a of the fifth reed 6 a , the sixth reed 6 b , the seventh reed 6 c and the eighth reed 6 d are fixed at different positions of the second carrier 22 , respectively.

[0318] It is understood that after the camera module 100 is assembled, it can be installed in the electronic device 1000. For example, the second carrier 22 of the camera module 100 can be directly fixed to the device housing 200 (see Figures 1 and 2), so that the camera module 100 is connected to the structural components of the electronic device 1000.

[0319] The gimbal module 2 mentioned above can control the camera subject 1 to rotate about the first rotation axis P1 and the second rotation axis P2, thereby achieving optical image stabilization of the camera module and improving the imaging quality of the camera module. The first rotation axis P1 intersects the second rotation axis P2. It is understood that the gimbal module 2 can control the camera subject 1 to achieve large-angle and low-frequency stabilization. For example, the gimbal module 2 of this embodiment has an stabilization angle greater than 0.8° and a frequency less than 4Hz. The following describes an stabilization motor in the image sensor assembly 12 in conjunction with the relevant drawings. The stabilization motor controls the movement of the image sensor 122 in the XY plane, achieving optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100. It is understood that the stabilization motor can control the image sensor 122 to achieve small-angle and high-frequency stabilization. For example, the stabilization angle of the stabilization motor is less than 0.8° and the frequency is greater than 4Hz.

[0320] In some embodiments, the anti-shake motor may include, but is not limited to, a coil and a magnet. When the coil is energized, the magnet generates a Lorentz force, which can act on the image sensor to propel it into motion. When the magnetic field is constant, the magnitude and direction of the Lorentz force can be controlled by controlling the magnitude and direction of the coil current, thereby controlling the displacement and direction of the image sensor along each axis.

[0321] Specifically, coils are provided on the first, second and third sides of the image sensor. The coils on the first, second and third sides push the image sensor to move along the X-axis, Y-axis and R-axis to achieve three-axis optical image stabilization.

[0322] In the optical image stabilization motor, the number of coils on each side, the coil arrangement position on each side, and the coil size can be set according to actual needs and are not limited here.

[0323] In one embodiment, a three-coil electromagnetic drive scheme.

[0324] In a three-coil electromagnetic driving scheme, the optical image stabilization motor may include a first coil, a second coil, and a third coil.

[0325] In some embodiments, the first coil is disposed on a first side of the image sensor, and the second coil is disposed on a second side of the image sensor. The first side and the second side are opposite sides, i.e., the first coil is located on an opposite side of the second coil. The third coil is disposed on a third side of the image sensor, adjacent to both the first and second sides.

[0326] The driver chip outputs a first current signal through a current generating structure (e.g., a PWM drive structure) based on the displacement amount and displacement direction of the image sensor in the X-axis direction. The first current signal is applied to the first coil, so that the first coil generates a force acting on the image sensor under the action of the magnetic field, thereby applying a force along the X-axis direction to the image sensor, thereby driving the image sensor to translate along the X-axis direction.

[0327] The driver chip outputs a second current signal through a current generating structure (e.g., a PWM drive structure) based on the displacement amount and displacement direction of the image sensor in the R-axis direction; the second current signal is applied to the second coil so that the second coil generates a force acting on the image sensor under the action of the magnetic field, thereby applying a torque along the R-axis to the image sensor, thereby driving the image sensor to rotate along the R-axis.

[0328] The driver chip outputs a third current signal through a current generating structure (e.g., a PWM drive structure) based on the displacement amount and displacement direction of the image sensor in the Y-axis direction. The third current signal is applied to the third coil so that the third coil generates a force acting on the image sensor under the action of the magnetic field, thereby applying a force along the Y-axis direction to the image sensor, thereby driving the image sensor to translate along the Y-axis.

[0329] In some embodiments, to further reduce crosstalk and thus reduce crosstalk compensation during drive control, the mechanical structure design can be such that the mechanical center coincides with the geometric center of the image sensor and the center of gravity of the image sensor, thereby achieving "multi-center integration." The mechanical center is the mechanical center of the force along the X-axis and the force along the Y-axis generated by the third coil.

[0330] At this point, the normal line passing through the center of the first coil passes through the geometric center of the image sensor, the normal line passing through the center of the second coil does not, and the normal line passing through the center of the third coil passes through the geometric center of the image sensor. Furthermore, the center of gravity and the geometric center of the image sensor coincide. Of course, in other embodiments, if "multi-center integration" is not considered, the normal line passing through the center of the first coil and the normal line passing through the center of the second coil may not pass through the center of the image sensor. However, in this case, when pushing the image sensor along each axis, more crosstalk will be generated, requiring the control algorithm to perform more crosstalk compensation. This increased crosstalk compensation required by the control algorithm will reduce the real-time performance of optical image stabilization compensation control.

[0331] For example, referring to the schematic diagram of the three-coil electromagnetic drive scheme shown in Figure 30, after coils 92, 95 and 96 are energized, they can generate a Lorentz force acting on the image sensor 93 under the action of magnets 98, 99a and 99b, so as to push the image sensor 93 to move on the X-axis, Y-axis and R-axis.

[0332] Among them, coil 96 corresponds to the first coil mentioned above, coil 95 corresponds to the second coil mentioned above, and coil 92 corresponds to the third coil mentioned above. Therefore, in Figure 30, the first side is the left side of the image sensor 93, the second side is the right side of the image sensor 93, and the third side is the upper side of the image sensor 93. In the embodiment of the present application, the magnetization direction of the magnet can be a uniform magnetization of four poles of a magnet, or two identical magnets can be connected together after bipolar magnetization. As shown in Figure 30, two magnets including N poles and S poles are connected together. After the coils are energized, a leftward Lorentz force F is generated in the magnetic field of the two magnets. Of course, the magnetization direction of the magnet can also be opposite to that shown in Figure 30, which is not limited here.

[0333] As shown in FIG30 , according to the Lorentz force and the left-hand rule, when the coil 92 is energized, it can generate a Lorentz force F along the Y-axis under the action of the magnetic field of the magnet 99a. y When the coil 95 is energized, it can generate a Lorentz force F along the Y axis under the action of the magnetic field of the magnet 98. yr When the coil 96 is energized, the magnetic field of the magnet 99b generates a Lorentz force F along the X-axis. x .

[0334] In FIG30 , the image sensor moves along the positive direction of the X-axis under the action of , and moves along the negative direction of the Y-axis under the action of .

[0335] When coil 95 is energized, the Lorentz force generated by the magnetic field produces a torque on image sensor 93 because it does not coincide with the center O of image sensor 93, resulting in a moment arm. This torque causes image sensor 93 to rotate along the R-axis within the XY plane. In Figure 30 , image sensor 93 rotates counterclockwise within the XY plane due to the torque.

[0336] 30 also shows high-precision position sensors 91, 94, and 97. Position sensor 91 is placed in the middle of coil 92, position sensor 94 is placed in the middle of coil 95, and position sensor 97 is placed in the middle of coil 96.

[0337] Position sensor 91 is used in conjunction with magnet 99a to detect the position of the image sensor. Position sensor 94 is used in conjunction with magnet 98 to detect the position of the image sensor. Position sensor 97 is used in conjunction with magnet 99b to detect the position of the image sensor. In specific applications, position sensor 91 can detect the position of the image sensor in the yaw direction in real time and feed the detected position back to the target position controller. Position sensor 94 can detect the position of the image sensor in the roll direction in real time and feed the detected position back to the target position controller. Position sensor 97 can detect the position of the image sensor in the pitch direction in real time and feed the detected position back to the target position controller.

[0338] It should be understood that the diagram in FIG30 , including position sensor 91, coil 92, image sensor 93, position sensor 94, coil 95, coil 96, and position sensor 97, is a top view. The diagrams of magnets 98, 99a, and 99b are front views viewed from the negative Y-axis direction toward the positive Y-axis direction. The diagram of the magnets including the north and south poles is a side view viewed from the positive X-axis direction toward the negative X-axis direction.

[0339] It can be seen that the three-axis decoupling negative feedback of pitch, yaw and roll is realized through position sensor 91 , position sensor 94 and position sensor 97 .

[0340] Based on the decoupling negative feedback of pitch, yaw and roll, the mutual decoupling of the three-axis drive control is achieved.

[0341] It is understood that the electromagnetic drive scheme of the embodiment of the present application is not limited to the three-coil electromagnetic drive scheme mentioned above, and other variations can be obtained based on the content mentioned above. For example, based on the three-coil electromagnetic drive scheme shown in Figure 30, three coils can be used to replace coil 96, and three coils can be used to replace coil 95 to obtain a seven-coil electromagnetic drive scheme. For another example, based on the three-coil electromagnetic drive scheme shown in Figure 30, three coils can be used to replace coil 96, three coils can be used to replace coil 95, and three coils can be used to replace coil 92 to obtain a nine-coil electromagnetic drive scheme.

[0342] In the embodiments of the present application, different electromagnetic drive schemes can be obtained by varying the coil size, number of coils, and coil positions. The drive control logic of these different electromagnetic drive schemes is similar. The driver chip applies currents of corresponding magnitude and direction to the corresponding coils based on the displacement and direction of the image sensor on each axis, thereby generating a Lorentz force acting on the image sensor to drive the image sensor in various directions for jitter compensation. The difference is that the electromagnetic drive scheme with a larger number of coils will have a greater electromagnetic driving force and better drive stability.

[0343] It can be understood that the driving method in the embodiments of the present application is not limited to the electromagnetic driving method mentioned above.

[0344] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the scope of protection of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application.
