Abstract
Description
Technical Field
[0001] The present application relates to the field of camera technology, and in particular to a camera module and an electronic device. Background Art
[0002] With the popularity and development of smart phones, mobile phone photography has become a common way of shooting, and mobile phones with both optical image stabilization and autofocus functions are increasingly popular among users. The traditional camera module includes a gimbal module and a camera body. The gimbal module achieves image stabilization of the camera body by controlling the movement of the camera body in a direction perpendicular to the optical axis. However, due to the unreasonable structural setting of the gimbal module, the size of the camera module is relatively large. Summary of the invention
[0003] 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.
[0004] In a first aspect, a camera module is provided. The camera module includes a camera body, a first carrier, a second carrier, a first driving mechanism, and a second driving mechanism. Exemplarily, the camera body is used to collect light and convert image information carried by the light into an electrical signal.
[0005] The first carrier is arranged around the camera subject, and the second carrier is arranged around the first carrier;
[0006] 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;
[0007] 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 around a second rotation axis relative to the second carrier, and 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.
[0008] It is understandable that when the camera module collects light, if the electronic device shakes due to external force, the shaking stroke of the camera subject can be offset by controlling the camera subject 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 subject caused by the shaking. In other words, the camera module of the present application can control the camera subject to rotate around the first rotation axis and / or around the second rotation axis through the gimbal module, so as to achieve optical image stabilization of the camera module and improve the imaging quality of the camera module.
[0009] In this embodiment, the first carrier is arranged to surround the imaging subject, and the second carrier is arranged to surround the first carrier. At this time, the imaging subject, the first carrier and the second carrier are arranged substantially in a nested manner.
[0010] It can be understood that the first carrier of this embodiment has the function of "one object for multiple uses". On the one hand, the first carrier can cooperate with the second carrier to serve as a stator for the camera body to rotate around the first rotation axis, and on the other hand, the first carrier can serve as a mover for the camera body to rotate around the second rotation axis. In this way, the first carrier can play a role of structural reuse, thereby simplifying the structure of the gimbal module, thereby realizing the miniaturization of the gimbal module.
[0011] In addition, the second carrier of the present 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 subject to rotate around the first rotation axis. On the other hand, the second carrier can serve as a stator for the camera subject 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 driving mechanism and the second driving mechanism of the gimbal module. In this way, the second carrier can play a role of structural reuse, thereby simplifying the structure of the gimbal module, thereby realizing the miniaturization setting of the gimbal module.
[0012] It can be understood that the second carrier can be used 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 set 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 realizing 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, reducing the cost investment.

[0115] Figure 1 It is a structural diagram of an electronic device 1000 provided in an embodiment of the present application.
[0116] like Figure 1 As shown, the electronic device 1000 can 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, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses or a VR helmet. Figure 1 The electronic device 1000 in the illustrated embodiment is described by taking a mobile phone as an example.
[0117] Figure 2 yes Figure 1 The electronic device 1000 is shown as a partial cross-sectional view of one embodiment along line AA.
[0118] like Figure 1 and Figure 2 As shown, 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. Figure 1 The following figures and the related drawings only schematically illustrate some components of the electronic device 1000, and the actual shapes, sizes, positions and structures of these components are not limited to the following. Figure 1 In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may not include the screen 300 .
[0119] like Figure 1 and Figure 2 As shown, the device housing 200 may include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. Exemplarily, the back cover 202 may be fixedly connected to the frame 201 by adhesive. The back cover 202 may also be an integrally formed structure with the frame 201, that is, the back cover 202 and the frame 201 are an integral structure.
[0120] In one embodiment, the screen 300 may be located on a side of the frame 201 away from the back cover 202. In this case, the screen 300 and the back cover 202 may be located on both sides of the frame 201, respectively. 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 may be used to place components of the electronic device 1000, such as a battery, a receiver, or a microphone. The screen 300 may be a flat screen or a curved screen.
[0121] For example, the camera module 100 may be located inside the electronic device 1000. The camera module 100 may be located on the side of the screen 300 facing the back cover 202. The back cover 202 may be provided with a light-transmitting hole 203. The shape of the light-transmitting hole 203 is not limited to the following. Figure 1 The light-transmitting hole 203 connects the inside of the electronic device 1000 to the outside of the electronic device 1000. Light outside the electronic device 1000 can enter the inside of the electronic device 1000 through the light-transmitting hole 203. The camera module 100 can collect the light entering the inside of the electronic device 1000.
[0122] Exemplarily, the camera module 100 may 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 may 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 is understood that the camera module 100 of this embodiment is described by taking a common camera module as an example.
[0123] 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 the Y-axis. The thickness direction of the camera module 100 is the Z-axis. It is understandable 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 for example.
[0124] Figure 3 yes Figure 1 A structural schematic diagram of an implementation of a camera module 100 is shown. Figure 4 yes Figure 3 A partially exploded schematic diagram of an embodiment of a camera module 100 is shown.
[0125] like Figure 3 and Figure 4 As shown, the camera module 100 may include a camera body 1 and a pan-tilt module 2. The camera body 1 is arranged on the pan-tilt module 2.
[0126] Exemplarily, the camera body 1 is used to collect light and convert image information carried by the light into electrical signals.
[0127] Exemplarily, the gimbal module 2 can control the camera body 1 to rotate around the first rotation axis P1, and can also control the camera body 1 to rotate around the 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 can be understood that the first rotation axis P1 and the second rotation axis P2 can be the length extension lines of the physical axis, or the length extension lines of the virtual axis.
[0128] Exemplarily, the extension direction of the first rotation axis P1 may be the X-axis direction. The extension direction of the second rotation axis P2 may be the Y-axis direction. The optical axis direction of the camera module 100 is the Z-axis direction. It is understandable that the gimbal module 2 may independently control the camera subject 1 to rotate around the first rotation axis P1, may independently control the camera subject 1 to rotate around the second rotation axis P2, and may 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 can be 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 may rotate along a plane that is perpendicular to the Y-axis direction (i.e., the XZ plane). When the gimbal module 2 controls the camera body 1 to rotate around the first rotation axis P1 and the second rotation axis P2 at the same time, 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.
[0129] 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 shakes due to external force, the pan-tilt module 2 can control the camera subject 1 to rotate around the X-axis and / or around the Y-axis to offset the shaking stroke of the camera subject 1, so as to avoid or reduce the position bias of the camera subject 1 caused by 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 of the camera subject 1 controlled 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.
[0130] Figure 5 yes Figure 4 The camera body 1 is shown in a partially exploded view in one embodiment. Figure 6 yes Figure 5 The camera body 1 is shown as a partially exploded view at another angle.
[0131] See also Figure 5 and Figure 6 , and combined with Figure 4 As shown, 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 can be used to collect light and converge the light to the image sensor assembly 12. The image sensor assembly 12 collects light and converts the image information carried by the light into an electrical signal.
[0132] It is understandable that the camera body 1 may further include more structures. For example, the camera body 1 may further include a variable aperture (not shown). The variable aperture is located on the light incident side of the lens assembly 11 and is fixedly connected to the lens assembly 11. The size of the aperture hole of the variable aperture can be automatically adjusted. Light can enter the lens assembly 11 through the aperture hole of the variable aperture.
[0133] like Figure 5 and Figure 6 As shown, the lens assembly 11 includes a first housing 11a and a focus lens 11b. The lens of the focus lens 11b can move along the Z-axis direction to achieve auto focus (AF). The first housing 11a is provided with a first through hole 11c. The first through hole 11c connects the inside and the outside of the first housing 11a. The focus lens 11b is installed inside the first housing 11a, and a part of the focus lens 11b is exposed outside the first housing 11a through the first through hole 11c.
[0134] It is understandable that the structures of the first housing 11a and the focus lens 11b can adopt the structures of the conventional first housing and the focus lens, and the specific application is not limited thereto. 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. In this case, the lens assembly 11 includes a fixed focus lens.
[0135] like Figure 5 and Figure 6 As shown, 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.
[0136] 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 connected in sequence. The first sub-side portion 1131 is connected to the first side portion 111 , and the third sub-side portion 1133 is connected to the second side portion 112 .
[0137] 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.
[0138] 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 , and the sixth sub-side portion 1143 is connected to the first side portion 111 .
[0139] Exemplarily, the angle between the fourth sub-side portion 1141 and the fifth sub-side portion 1142 and the angle between the fifth sub-side portion 1142 and the sixth sub-side portion 1143 are both obtuse angles.
[0140] Exemplarily, the cross-section of the first housing 11 a parallel to the XY plane is substantially octagonal in shape.
[0141] The first housing 11a is also 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 convexly arranged on the outer surface of the first housing 11a. The extension line of the center line of the first rotating shaft 111a or the extension line of the center line of the second rotating shaft 111b may constitute the first rotation axis P1. It is understandable that the first housing 11a may be an integrally formed structure with the first rotating shaft 111a. The first housing 11a may be an integrally formed structure with the second rotating shaft 111b.
[0142] Exemplarily, the first rotating shaft 111a is protruded from the first side portion 111 of the first housing 11a. The second rotating shaft 111b is protruded from the second side portion 112 of the first housing 11a. The first rotating shaft 111a and the second rotating shaft 111b may be parallel to the X-axis direction.
[0143] Figure 7 yes Figure 5 A partial cross-sectional view of one embodiment of image sensor assembly 12 is shown at line BB.
[0144] like Figure 7As shown, 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. At this time, the image sensor 122 and the module circuit board 121 can transmit signals to each other. 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 in the light-transmitting hole 125. The filter 124 is also arranged opposite to the image sensor 122. The filter 124 can be used to filter infrared light or blue light in the light before entering the image sensor 122, so as to ensure that the image sensor 122 has a better imaging quality.
[0145] like Figure 6 and Figure 7 As shown, when the image sensor assembly 12 is fixed on the light-exiting side of the lens assembly 11, the image sensor 122, the filter 124 and the focus lens 11b are arranged in sequence in the Z-axis direction. At this time, the image sensor 122 is located on the light-exiting side of the focus lens 11b. The filter 124 is located between the focus lens 11b and the image sensor 122.
[0146] Exemplarily, the image sensor assembly 12 includes a second housing 126. The second housing 126 can be fixed on the module circuit board 121, or on 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, and the second through hole 127 connects the inside and the outside 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 relative to the filter 124 and the image sensor 122 through the second through hole 127 of the second housing 126.
[0147] It is understandable that the image sensor assembly 12 may also 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 image sensor 122 to move 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 generates jitter 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 jitter stroke of the focus lens 11b in the XY plane, so as to avoid or reduce the position offset of the focus lens 11b caused by the jitter. 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, realize the 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 below in conjunction with the relevant drawings.
[0148] The above specifically describes 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 specifically describes 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.
[0149] Figure 8 yes Figure 4 The shown diagram is a partial exploded view of the pan / tilt module 2 in one embodiment.
[0150] like Figure 8 As shown, 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 .
[0151] Fig. 9 yes Figure 8 The first carrier 21 is shown in a partially exploded view in one embodiment. Fig.10 yes Fig. 9 The first carrier 21 is shown as a partially exploded view at another angle. Fig.11 yes Fig. 9 The first carrier 21 is shown in a partially exploded view at yet another angle.
[0152] like Figures 9 to 11 As shown, the first carrier 21 includes a first bracket 21a, a first fixing member 21b and a second fixing member 21c.
[0153] Exemplarily, 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.
[0154] 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 connects the first side 211 of the first bracket 21a, and the third sub-side 2133 connects the second side 212 of the first bracket 21a.
[0155] 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.
[0156] Exemplarily, 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 .
[0157] Exemplarily, the angle between the fourth sub-side portion 2141 and the fifth sub-side portion 2142 and the angle between the fifth sub-side portion 2142 and the sixth sub-side portion 2143 are both obtuse angles.
[0158] Exemplarily, the cross-section of the first bracket 21 a parallel to the XY plane is substantially octagonal.
[0159] 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 shape of the cross section of the first bracket 21a parallel to the XY plane may be a quadrilateral, a pentagon, a hexagon, or a heptagon. When the first bracket 21a includes more structures, the shape of the cross section of the first bracket 21a parallel to the XY plane may be an n-gon, where n is greater than 8.
[0160] Exemplarily, the angle between two adjacent sides is 135°. At this time, the first bracket 21a is substantially in the shape of a regular octagon.
[0161] like Figures 9 to 11 As shown, the first bracket 21a is provided with a first groove 251 and a second groove 252 which are arranged opposite to each other. The first groove 251 and the second groove 252 form openings on the inner surface and the bottom surface of the first bracket 21a.
[0162] Exemplarily, the first groove 251 is located at the first side portion 211 of the first bracket 21 a. The second groove 252 is located at the second side portion 212 of the first bracket 21 a.
[0163] Exemplarily, the first groove 251 includes a first groove side wall 253 and a second groove side wall 254 that are oppositely disposed. The angle between the first groove side wall 253 and the second groove side wall 254 of the first groove 251 is an acute angle.
[0164] It is understandable that the second groove 252 and the first groove 251 adopt a similar or identical configuration.
[0165] like Fig.11 As shown, 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.
[0166] 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 .
[0167] It is understandable that although Fig.11 It is shown that the first bump 255 and the second bump 256 are arranged at intervals, but the first bump 255 can also be connected to the second bump 256, in which case the first bump 255 and the second bump 256 form one bump.
[0168] like Fig. 9 and Fig.10 As shown, 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.
[0169] 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 .
[0170] It is understandable that although Fig. 9 and Fig.10 It is shown that the third bump 257 and the fourth bump 258 are arranged at intervals, but the third bump 257 can also be connected to the fourth bump 258. In this case, the third bump 257 and the fourth bump 258 form one bump.
[0171] like Figures 9 to 11 As shown, the first bracket 21a is further provided with a third rotating shaft 259a and a fourth rotating shaft 259b. The third rotating shaft 259a and the fourth rotating shaft 259b can be on the same straight line, that is, the third rotating shaft 259a and the fourth rotating shaft 259b are colinear. The third rotating shaft 259a and the fourth rotating shaft 259b are convexly arranged on the outer surface of the first bracket 21a. The extension line of the center line of the third rotating shaft 259a or the extension line of the center line of the fourth rotating shaft 259b can constitute the second rotation axis P2.
[0172] Exemplarily, 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 may be parallel to the Y-axis direction.
[0173] Exemplarily, the third rotating shaft 259a and the fourth rotating shaft 259b are both cylindrical.
[0174] 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.
[0175] Fig.12 yes Figure 3 The camera module 100 shown is a partial structural schematic diagram of an embodiment.
[0176] like Fig.12 As shown, the camera body 1 is located inside the first bracket 21a. In other words, the first bracket 21a can be arranged around the camera body 1. Exemplarily, the first bracket 21a can be arranged around the lens assembly 11 of the camera body 1.
[0177] Exemplarily, 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.
[0178] Fig.13 yes Fig.12 The camera module 100 shown is a partial cross-sectional view of an embodiment along the CC line.
[0179] like Fig.13As shown, at least a portion of the first rotating shaft 111a of the lens assembly 11 is located in the first groove 251 of the first bracket 21a and is rotatably connected to the groove wall of the first groove 251. The first fixing member 21b is fixed to the first bracket 21a and covers the first groove 251. The first fixing member 21b is used to prevent the first rotating shaft 111a from escaping from the first groove 251.
[0180] 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.
[0181] Exemplarily, the first fixing member 21 b may be a metal sheet, such as a steel sheet or an aluminum sheet.
[0182] In other embodiments, the positions of the first rotating shaft 111 a of the lens assembly 11 and the first groove 251 of the first bracket 21 a may be swapped.
[0183] Fig.14 yes Fig.12 The camera module 100 shown is a partial structural schematic diagram of an embodiment.
[0184] like Fig.13 and Fig.14 As shown, illustratively, the first fixing member 21b supports the first rotating shaft 111a. The first fixing member 21b, the first groove side wall 253 of the first groove 251, and the second groove side wall 254 of the first groove 251 can roughly surround a triangle. At this time, the first fixing member 21b, the first groove side wall 253 of the first groove 251, and the second groove side wall 254 of the first groove 251 can realize three-point support for the first rotating shaft 111a. In this way, the connection stability between the first rotating shaft 111a and the first bracket 21a is better.
[0185] like Fig.13 As shown, at least a portion of the second rotating shaft 111b of the lens assembly 11 is located in the second groove 252 of the first bracket 21a and is rotatably connected to the groove wall of the second groove 252. The 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 rotating shaft 111b from escaping from the second groove 252. In other embodiments, the positions of the second rotating shaft 111b of the lens assembly 11 and the second groove 252 of the first bracket 21a can be swapped.
[0186] 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.
[0187] Exemplarily, the second fixing member 21c may be a metal sheet, such as a steel sheet or an aluminum sheet.
[0188] Exemplarily, the second fixing member 21c supports the second rotating shaft 111b. The second fixing member 21c can also realize three-point support with each groove 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.
[0189] 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, so that the connection stability between the camera body 1 and the first carrier 21 is better.
[0190] like Fig.13 As shown, the camera body 1 can be rotatably connected to the first bracket 21a via the first rotating shaft 111a and the second rotating shaft 111b. The first rotating shaft 111a and the second rotating shaft 111b can constitute a first rotating axis of the camera body 1. The camera body 1 can rotate relative to the first carrier 21 around the first rotating axis.
[0191] Exemplarily, 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 .
[0192] Fig.15 yes Figure 8 A schematic structural diagram of an implementation manner of the first driving mechanism 23 is shown.
[0193] like Fig.15 As shown, the first driving mechanism 23 includes a first shape memory alloy (SMA) wire 3a, a second SMA wire 3b, a first reed 4a, a second reed 4b, a third reed 4c and a fourth reed 4d.
[0194] It is understandable that the first SMA wire 3a and the second SMA wire 3b are made of shape memory alloy (SMA) material, such as nickel-titanium alloy material. 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 a structure that uses its own deformation to generate relative displacement.
[0195] Fig.16 yes Fig.15 A schematic structural diagram of an implementation manner of the first reed 4a is shown. Fig.17 yes Fig.16The structure diagram of the first reed 4a shown is at another angle. Fig.18 yes Fig.16 The structure diagram of the first reed 4a shown is at another angle.
[0196] like Figures 16 to 18 As shown, the first spring piece 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.
[0197] For example, in the Z-axis direction, there is a height difference between the electrical connection end 43a of the first reed 4a and the first fixed end 41a. It is understandable that in the Z-axis direction, the first fixed end 41a can be located at the top of the electrical connection end 43a, or can be located at the bottom of the electrical connection end 43a. Figures 16 to 18 It is illustrated that in the Z-axis direction, the first fixing end 41 a may be located on the top of the electrical connection end 43 a .
[0198] Exemplarily, in the X-axis direction, there is a distance between the electrical connection end 43a and the first fixed end 41a. It is understandable that in the X-axis direction, the first fixed end 41a can be located on the left side of the electrical connection end 43a, or can be located on the right side of the electrical connection end 43a. Figures 16 to 18 It is illustrated that in the Z-axis direction, the first fixing end 41 a may be located on the left side of the electrical connection end 43 a .
[0199] Exemplarily, in the Y-axis direction, there is a distance between the electrical connection end 43a and the first fixed end 41a. It is understandable that in the Y-axis direction, the first fixed end 41a can be located at the rear side of the electrical connection end 43a, or can be located at the front side of the electrical connection end 43a. Figures 16 to 18 It is illustrated that in the Y-axis direction, the first fixing end 41 a may be located at the rear side of the electrical connection end 43 a .
[0200] like Figures 16 to 18 As shown, 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 away from the second section 45a is the first fixed end 41a. The end of the third section 46a away from the second section 45a is the second fixed end 42a. At least part of the second section 45a is the electrical connection end 43a.
[0201] For example, the first segment 44a of the first reed 4a includes a first subsegment 441a and a second subsegment 442a connecting the first subsegment 441a. The first subsegment 441a of the first reed 4a connects the second segment 45a of the first reed 4a.
[0202] Exemplarily, the first sub-segment 441a of the first reed 4a is bent relative to the second segment 45a of the first reed 4a along the Y-axis direction, and the angle a1 between the first sub-segment 441a and the second segment 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.
[0203] Exemplarily, the first sub-segment 441a of the first reed 4a is bent relative to the second sub-segment 442a of the first reed 4a along the Z-axis direction, and the angle b1 between the first sub-segment 441a and the second sub-segment 442a of the first reed 4a satisfies: 90° < b1 < 180°.
[0204] Exemplarily, the thickness of the first sub-segment 441a of the first reed 4a is greater than the thickness of the second sub-segment 442a of the first reed 4a.
[0205] Exemplarily, the third segment 46a of the first reed 4a includes a fixed segment 461a, a deformation segment 462a, and a connection segment 463a connected in sequence. In other words, the deformation segment 462a of the first reed 4a is connected between the fixed segment 461a and the connection segment 463a. Among them, the connection segment 463a of the first reed 4a is connected to the second segment 45a of the first reed 4a.
[0206] Exemplarily, the first end of the fixed segment 461a of the first reed 4a is disposed opposite to the first end of the connection segment 463a of the first reed 4a. The second end of the fixed segment 461a of the first reed 4a is disposed opposite to the second end of the connection segment 463a of the first reed 4a. One end of the deformation 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 connection segment 463a of the first reed 4a. At this time, the third segment 46a of the first reed 4a is substantially Z-shaped.
[0207] Exemplarily, the thickness of the deformation segment 462a of the first reed 4a is less than the fixed segment 461a and the connection segment 463a of the first reed 4a.
[0208] It can be understood that the second reed 4b and the first reed 4a can be a symmetric or partially symmetric structure, or different structures. In this embodiment, the second reed 4b and the first reed 4a are symmetric structures. For the basic design of the component structure of the second reed 4b, the design of the connection relationship between components, and the design of the connection relationship between components and other structures outside the component, the relevant solutions of the first reed 4a can be referred to. At the same time, it is allowed that there are some differences in the detailed structure or position arrangement of the components between the second reed 4b and the first reed 4a.
[0209] It is understandable that the structures of the third reed 4c and the fourth reed 4d are similar to or the same as the structures of the first reed 4a and the second reed 4b, and the details will not be repeated here.
[0210] Fig.19 yes Figure 3 The camera module 100 shown is a partial structural schematic diagram of an embodiment. Fig. 20 yes Fig.12 The shown is a partial cross-sectional view of an embodiment of the camera module 100 at DD.
[0211] like Fig.19 As shown, the first fixed end 41a of the first reed 4a is fixed on 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 on 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. Among them, the electrical connection end 43a of the first reed 4a is arranged opposite to the electrical connection end 43b of the second reed 4b. 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.
[0212] Exemplarily, 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 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 from the second sub-side portion 1132 of the lens assembly 11 of the camera subject 1.
[0213] like Fig.19 As shown, the electrical connection end 43a of the first spring piece 4a is electrically connected to one end of the first SMA wire 3a. The electrical connection end 43b of the second spring piece 4b is electrically connected to the other end of the first SMA wire 3a. In this way, the first SMA wire 3a is electrically connected between the electrical connection end 43a of the first spring piece 4a and the electrical connection end 43b of the second spring piece 4b. Exemplarily, the first SMA wire 3a is parallel to the extension direction of the first rotation axis P1, that is, the X-axis direction.
[0214] like Fig. 20 As shown, the second fixed end 42a of the first reed 4a is fixed to the first protrusion 255 of the first bracket 21a. The second fixed end 42b of the second reed 4b (see Fig.19 ) is fixed to the second protrusion 256 of the first bracket 21a (see Fig.11 ).
[0215] like Fig.19 and Fig. 20 As shown, when the first SMA wire 3a is energized, the first SMA wire 3a contracts. On the one hand, the first end of the first SMA wire 3a applies a pulling force along the positive direction of the X-axis to the electrical connection end 43a of the first spring 4a ( Fig.19 The direction of the pulling force is indicated by a thick arrow. The first fixed end 41a of the first spring 4a is subjected to a first component force along the positive direction of the X axis and a second component force along the negative direction of the Z axis ( Fig.19 The direction of the pulling force is indicated by a thick arrow. On the other hand, the second end of the first SMA wire 3a applies a pulling force along the negative direction of the X-axis to the electrical connection end 43b of the second spring leaf 4b ( Fig.19 The direction of the pulling force is indicated by a thick arrow. The first fixed end 41b of the second spring 4b is subjected to a third force component along the negative direction of the X axis and a fourth force component along the negative direction of the Z axis ( Fig.19 The direction of the pulling force is indicated by a thick arrow. The first force component and the third force component can be substantially offset. Under the action of the second force component and the fourth force component, the camera body 1 can be moved through the first rotating shaft 111a (see Fig.13 ) and the second rotating shaft 111b (see Fig.13 ) rotates counterclockwise relative to the first carrier 21.
[0216] Fig.21 yes Fig.19 The camera module 100 shown is a partial structural schematic diagram at another angle.
[0217] like Fig.21 As shown, the first fixed end 41c of the third reed 4c is fixed on the camera subject 1. The electrical connection end 43c and the second fixed end 42c of the third reed 4c can be spaced apart from the camera subject 1. The first fixed end 41d of the fourth reed 4d is fixed on the camera subject 1. The electrical connection end 43d and the second fixed end 42d of the fourth reed 4d are spaced apart from the camera subject 1. Among them, the electrical connection end 43c of the third reed 4c is arranged opposite to the electrical connection end 43d of the fourth reed 4d. 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.
[0218] Exemplarily, the first fixed end 41c of the third spring piece 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 piece 4c are both opposite to and spaced from the fifth sub-side portion 1142 of the lens assembly 11. The first fixed end 41d of the fourth spring piece 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 piece 4d can both be opposite to and spaced from the fifth sub-side portion 1142 of the lens assembly 11.
[0219] like Fig.21 As shown, the electrical connection end 43c of the third spring piece 4c is electrically connected to one end of the second SMA wire 3b. The electrical connection end 43d of the fourth spring piece 4d is electrically connected to the other end of the second SMA wire 3b. In this way, the second SMA wire 3b is electrically connected between the electrical connection end 43c of the third spring piece 4c and the electrical connection end 43d of the fourth spring piece 4d. Exemplarily, the second SMA wire 3b is parallel to the extension direction of the first rotation axis P1, that is, the X-axis direction.
[0220] like Fig. 20 As shown, the second fixed end 42c of the third spring piece 4c is fixed to the third protrusion 257 of the first bracket 21a. The second fixed end 42d of the fourth spring piece 4d is fixed to the fourth protrusion 258 of the first bracket 21a (see Fig.10 ).
[0221] like Fig. 20 and Fig.21 As shown, when the second SMA wire 3b is energized, the second SMA wire 3b contracts. On the one hand, the first end of the second SMA wire 3b applies a tensile force along the negative direction of the X-axis to the electrical connection end 43c of the third spring 4c ( Fig.21 The direction of the pulling force is indicated by a thick arrow. The first fixed end 41c of the third spring 4c is subjected to the fifth force component along the negative direction of the X axis and the sixth force component along the negative direction of the Z axis ( Fig.21 The direction of the pulling force is indicated by a thick arrow. On the other hand, the second end of the second SMA wire 3b applies a pulling force along the positive direction of the X-axis to the electrical connection end 43d of the fourth spring leaf 4d ( Fig.21 The direction of the pulling force is indicated by a thick arrow. The first fixed end 41d of the fourth spring 4d is subjected to the seventh force component along the positive direction of the X axis and the eighth force component along the negative direction of the Z axis ( Fig.21 The direction of the pulling force is indicated by a thick arrow. The fifth force component and the seventh force component can be substantially offset. Under the action of the sixth force component and the eighth force component, the camera body 1 can rotate relative to the first carrier 21 in a clockwise direction via the first rotating shaft 111a and the second rotating shaft 111b.
[0222] A specific implementation method 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 is described below in conjunction with the related drawings.
[0223] like Figures 19 to 21 As shown, in one embodiment, the first SMA wire 3a and the second SMA wire 3b are energized to the maximum current at the same time, and the first SMA wire 3a and the second SMA wire 3b are contracted. On the one hand, the first end of the first SMA wire 3a applies a pulling force along the positive direction of the X-axis to the electrical connection end 43a of the first spring piece 4a. The first fixed end 41a of the first spring piece 4a is subjected to a first component force along the positive direction of the X-axis and a second component force along the negative direction of the Z-axis. On the other hand, the second end of the first SMA wire 3a applies a pulling force along the negative direction of the X-axis to the electrical connection end 43b of the second spring piece 4b. The first fixed end 41b of the second spring piece 4b is subjected to a third component force along the negative direction of the X-axis and a fourth component force along the negative direction of the Z-axis. On the other hand, the first end of the second SMA wire 3b applies a pulling force along the negative direction of the X-axis to the electrical connection end 43c of the third spring piece 4c. The first fixed end 41c of the third spring piece 4c is subjected to a fifth component force along the negative direction of the X-axis and a sixth component force along the negative direction of the Z-axis. On the other hand, the second end of the second SMA wire 3b applies a pulling force along the positive direction of the X-axis to the electrical connection end 43d of the fourth spring leaf 4d. The first fixed end 41d of the fourth spring leaf 4d is subjected to the seventh force component along the positive direction of the X-axis and the eighth force component along the negative direction of the Z-axis. Among them, the first force component and the third force component can be roughly offset. The fifth force component and the seventh force component can be roughly offset. In addition, the resultant force of the second force component and the fourth force component can be roughly offset by the resultant force of the sixth force component and the eighth force component. At this time, the camera subject 1 can be in a balanced state.
[0224] When the current on the first SMA wire 3a is controlled to be greater than the current on the second SMA wire 3b (i.e., the current on the second SMA wire 3b is reduced), the resultant force of the second force component and the fourth force component is greater than the resultant force of the sixth force component and the eighth force component. At this time, the camera body 1 can rotate clockwise relative to the first carrier 21 through the first rotating shaft 111a and the second rotating shaft 111b.
[0225] When the current on the first SMA wire 3a is controlled to be smaller than the current on the second SMA wire 3b (i.e., the current on the first SMA wire 3a is reduced), the resultant force of the sixth force component and the eighth force component is greater than the resultant force of the second force component and the fourth force component. At this time, the camera body 1 can rotate counterclockwise relative to the first carrier 21 through the first rotating shaft 111a and the second rotating shaft 111b.
[0226] Exemplarily, the angle at which the camera subject 1 rotates relative to the first carrier 21 around the first rotation axis is within a range greater than 0.8°.
[0227] Exemplarily, the angle of rotation of the imaging body 1 relative to the first carrier 21 about the first rotation axis is in the range of 1° to 4°.
[0228] The following introduces simulation data of the rotation of the imaging body 1 relative to the first carrier 21 through the first rotating shaft 111a and the second rotating shaft 111b.
[0229] In one embodiment, the wire 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 reed 4a can descend by 370 micrometers along the Z-axis direction. In this way, the first reed 4a can magnify the contraction distance of the first SMA wire 3a by 3.7 times, that is, the magnification factor of the first reed 4a is 3.7. At this time, the imaging body 1 can rotate 3° relative to the first carrier 21 under the pulling of the first reed 4a through the first rotating shaft 111a and the second rotating shaft 111b.
[0230] It can be understood that the magnitude of the magnification factor of the first reed 4a is related to the rotation effect of the imaging body 1. Generally, if the magnification factor of the first reed 4a is relatively large, the imaging body 1 is prone to instability during rotation and the anti-shake accuracy is poor. If the magnification factor of the first reed 4a is relatively small, the rotation angle of the imaging body 1 is small and the anti-shake effect is poor. In this embodiment, by setting the thickness, shape, and bending angle of each section of the first reed 4a, a first reed 4a with a suitable magnification factor is set, so that the imaging body 1 can be stable during rotation, the anti-shake accuracy is better, and the rotation angle of the imaging body 1 is not small and the anti-shake effect is better.
[0231] Exemplarily, the magnification factor of the first reed 4a is in the range of 4 to 5.
[0232] 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. Details are not described here again.
[0233] It can be understood that by setting the first sub-section 441a of the first reed 4a to be bent along 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, the distance that the first fixed end 41a of the first reed 4a moves along the Z-axis direction can be reduced while ensuring that the rotation angle of the imaging body 1 remains unchanged, thereby reducing the power consumption of the first SMA wire 3a.
[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. Details are not described here again.
[0235] An implementation of the assembly steps of the camera body 1 , the first carrier 21 , and the first driving mechanism 23 is described below.
[0236] like Figures 9 to 11 As shown, the first carrier 21 is inverted, that is, the bottom surface of the first carrier 21 faces. 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.
[0237] like Fig.19 and Fig.21 As shown, the first fixed end 41a of the first reed 4a, the first fixed end 41b of the second reed 4b, the first fixed end 41c of the third reed 4c, and the first fixed end 41d of the fourth reed 4d are respectively fixed at different positions of the camera body 1, and the electrical connection end 43a of the first reed 4a is arranged opposite to the electrical connection end 43b of the second reed 4b. 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 end 43b of the third reed 4c is arranged opposite to the electrical connection end 43d of the fourth reed 4d. 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 a side of the electrical connection end 43d of the fourth reed 4d away from the third reed 4c.
[0238] like Fig.19 and Fig.21 As shown, the first SMA wire 3a is electrically connected between the electrical connection end 43a of the first spring piece 4a and the electrical connection end 43b of the second spring piece 4b, and the second SMA wire 3b is electrically connected between the electrical connection end 43c of the third spring piece 4c and the electrical connection end 43d of the fourth spring piece 4d.
[0239] like Fig.12 and Fig.13 As shown, the camera body 1 is turned upside down, the first rotating 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 rotating shaft 111 b is aligned with the second groove 252 and assembled into the second groove 252 .
[0240] 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. Exemplarily, the first fixing member 21b can be fixed to the first bracket 21a by a glue dispensing process.
[0241] 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. Exemplarily, the second fixing member 21c can be fixed to the first bracket 21a by a glue dispensing process.
[0242] like Fig. 20 As shown, 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.
[0243] Fig. 22 yes Figure 8 The second carrier 22 is shown in a partially exploded schematic diagram in one embodiment. Fig.23 yes Fig. 22 The structure schematic diagram of the second carrier 22 shown in another angle.
[0244] like Fig. 22 and Fig.23 As shown, the second carrier 22 includes a second bracket 22a, a third fixing member 22b and a fourth fixing member 22c.
[0245] 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.
[0246] 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 connects the first side 221 of the second bracket 22a, and the third sub-side 2233 connects the second side 222 of the second bracket 22a.
[0247] 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.
[0248] Exemplarily, 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 .
[0249] Exemplarily, the angle between the fourth sub-side portion 2241 and the fifth sub-side portion 2242 , and the angle between the fifth sub-side portion 2242 and the sixth sub-side portion 2243 are obtuse angles.
[0250] Exemplarily, the cross-section of the second bracket 22 a parallel to the XY plane is substantially octagonal.
[0251] It is understandable that the second bracket 22a may include fewer or more structures. For example, the shape of the cross section of the second bracket 22a parallel to the XY plane may be a quadrilateral, a pentagon, a hexagon or a heptagon, etc. When the second bracket 22a includes more structures, the second bracket 22a may include more sides. In this case, the shape of the cross section of the second bracket 22a parallel to the XY plane may be an n-gon, where n is greater than 8.
[0252] Exemplarily, the angle between two adjacent sides is 135°. At this time, the second bracket 22a is substantially in the shape of a regular octagon.
[0253] like Fig. 22 and Fig.23 As shown, the second bracket 22a is provided with a third groove 271 and a fourth groove 272 which are arranged opposite to each other.
[0254] Exemplarily, the third groove 271 is located at the second sub-side portion 2232 of the second bracket 22a. The fourth groove 272 is located at the fifth sub-side portion 2242 of the second bracket 22a.
[0255] It is understandable that the third groove 271 and the fourth groove 272 can be connected to the first carrier 21 (see Figures 9 to 11 ) The first groove 251 and the second groove 252 are similar or identical in configuration. The details are not described in detail here.
[0256] like Fig. 22 and Fig.23 As shown, 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.
[0257] 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.
[0258] It is understandable that although Fig. 22 and Fig.23 It is shown that the first bump 275 and the second bump 276 are arranged at intervals, but the first bump 275 can also be connected to the second bump 276. In this case, the first bump 275 and the second bump 276 form one bump.
[0259] like Fig. 22 and Fig.23 As shown, 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.
[0260] Exemplarily, the third protrusion 277 and the fourth protrusion 278 may be protruded from the inner surface of the second side portion 222 .
[0261] It is understandable that although Fig. 22 and Fig.23 It is shown that the third bump 277 and the fourth bump 278 are arranged at intervals, but the third bump 277 can also be connected to the fourth bump 278. In this case, the third bump 277 and the fourth bump 278 form one bump.
[0262] Fig.24 yes Figure 3 The camera module 100 shown is a partial structural schematic diagram of an embodiment.
[0263] like Fig.24 As shown, 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.
[0264] Exemplarily, 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 from each other.
[0265] Fig.25 yes Fig.24 The camera module 100 shown is a partial cross-sectional view of an embodiment along line EE.
[0266] like Fig.25As shown, at least a portion of the third rotating shaft 259a of the first bracket 21a is located in the third groove 271 of the second bracket 22a and is rotatably connected to the groove 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 escaping from the third groove 271.
[0267] It is understandable that the third fixing member 22b can be fixed to the bottom surface of the second bracket 22a, or can be 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.
[0268] Exemplarily, the third fixing member 22b may be a metal sheet, such as a steel sheet or an aluminum sheet.
[0269] Exemplarily, the third fixing member 22b supports the third rotating shaft 259a. The third fixing member 22b can cooperate with the side walls of each groove 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 better.
[0270] 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.
[0271] like Fig.25 As shown, at least a portion of the fourth rotating shaft 259b of the first bracket 21a is located in the fourth groove 272 of the second bracket 22a and is rotatably connected to the groove wall of the fourth groove 272. The 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 escaping from 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 swapped.
[0272] 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.
[0273] Exemplarily, the fourth fixing member 22c may be a metal sheet, such as a steel sheet or an aluminum sheet.
[0274] Exemplarily, 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 side wall of the fourth groove 272. In this way, the connection stability between the fourth rotating shaft 259b and the second bracket 22a is better.
[0275] 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, so that the connection stability between the first carrier 21 and the second carrier 22 is better.
[0276] It is understandable that the camera body 1 and the first carrier 21 can be rotatably connected to the second carrier 22 via the third rotating shaft 259a and the fourth rotating shaft 259b. The third rotating shaft 259a and the fourth rotating shaft 259b can constitute the 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.
[0277] Exemplarily, 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 around the Y-axis direction on the XZ plane relative to the second carrier 22 .
[0278] Fig.26 yes Figure 8 A schematic structural diagram of an implementation scheme of the second driving mechanism 24 is shown.
[0279] like Fig.26 As shown, the second driving mechanism 24 includes a third SMA wire 5a, a fourth SMA wire 5b, a fifth reed 6a, a sixth reed 6b, a seventh reed 6c and an eighth reed 6d.
[0280] It is understandable 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 driving mechanism 24 are respectively configured the same or similarly 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 driving mechanism 23. The details are not repeated here.
[0281] Fig. 27 yes Figure 3 The camera module 100 shown is a partial structural schematic diagram of an embodiment.
[0282] like Fig. 27As shown, the first fixed end 61a of the fifth spring piece 6a is fixed on the first bracket 21a. The electrical connection end 63a and the second fixed end 62a of the fifth spring piece 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 piece 6b is fixed on the first bracket 21a. The electrical connection end 63b and the second fixed end 62b of the sixth spring piece 6b are both spaced apart from the first bracket 21a. Among them, the electrical connection end 63a of the fifth spring piece 6a is arranged opposite to the electrical connection end 63b of the sixth spring piece 6b. The first fixed end 61a of the fifth spring piece 6a is located on the side of the electrical connection end 63a of the fifth spring piece 6a away from the sixth spring piece 6b. The first fixed end 61b of the sixth spring piece 6b is located on the side of the electrical connection end 63b of the sixth spring piece 6b away from the fifth spring piece 6a.
[0283] Exemplarily, the first fixed end 61a of the fifth spring piece 6a can be fixed to the sixth sub-side portion 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 the first side portion 211 of the first bracket 21a and are arranged at intervals. The first fixed end 61b of the sixth spring piece 6b can be fixed to the first sub-side portion 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 the first side portion 211 of the first bracket 21a and are arranged at intervals.
[0284] like Fig. 27 As shown, the electrical connection end 63a of the fifth spring piece 6a is electrically connected to one end of the third SMA wire 5a. The electrical connection end 63b of the sixth spring piece 6b is electrically connected to the other end of the third SMA wire 5a. In this way, the third SMA wire 5a is electrically connected between the electrical connection end 63a of the fifth spring piece 6a and the electrical connection end 63b of the sixth spring piece 6b. Exemplarily, the third SMA wire 5a is parallel to the extension direction of the second rotation axis P2, that is, the Y-axis direction.
[0285] Fig.28 yes Fig. 27 The camera module 100 shown is a partial cross-sectional view of an embodiment of the camera module 100 taken along line FF.
[0286] like Fig.28 As shown, the second fixed end 62a of the fifth reed 6a is fixed to the first protrusion 275 of the second bracket 22a. The second fixed end 62b of the sixth reed 6b (see Fig. 27 ) is fixed to the second protrusion 276 of the second bracket 22a (see Fig.23 ).
[0287] like Fig. 27 and Fig.28As shown, when the third SMA wire 5a is energized, the third SMA wire 5a contracts. On the one hand, the first end of the third SMA wire 5a applies a pulling force along the positive direction of the Y axis to the electrical connection end 63a of the fifth spring leaf 6a. The first fixed end 61a of the fifth spring leaf 6a is subjected to a first component force along the positive direction of the X axis and a second component force along the negative direction of the Z axis. On the other hand, the second end of the third SMA wire 5a applies a pulling force along the negative direction of the Y axis to the electrical connection end 63b of the sixth spring leaf 6b. The first fixed end 61b of the sixth spring leaf 6b is subjected to a third component force along the negative direction of the X axis and a fourth component force along the negative direction of the Z axis. The first component force and the third component force can be roughly offset. Under the action of the second component force and the fourth component force, the camera subject 1 can be moved through the third rotating shaft 259a (please refer to Fig.25 ) and the fourth rotating shaft 259b (see Fig.25 ) rotates counterclockwise relative to the second carrier 22.
[0288] Fig.29 yes Fig. 27 The camera module 100 shown is a partial structural schematic diagram at another angle.
[0289] like Fig.29 As shown, the first fixed end 61c of the seventh spring 6c is fixed on 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 on 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. Among them, the electrical connection end 63c of the seventh spring 6c is arranged opposite to 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 spring 6d is located on the side of the electrical connection end 63d of the eighth spring 6d away from the seventh spring 6c.
[0290] Exemplarily, the first fixed end 61c of the seventh spring piece 6c can be fixed to the third sub-side portion 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 the second side portion 212 of the first bracket 21a and are arranged at intervals. The first fixed end 61d of the eighth spring piece 6d can be fixed to the fourth sub-side portion 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 the second side portion 212 of the first bracket 21a and are arranged at intervals.
[0291] like Fig.29As shown, the electrical connection end 63c of the seventh spring piece 6c is electrically connected to one end of the fourth SMA wire 5b. The electrical connection end 63d of the eighth spring piece 6d is electrically connected to the other end of the fourth SMA wire 5b. In this way, the fourth SMA wire 5b is electrically connected between the electrical connection end 63c of the seventh spring piece 6c and the electrical connection end 63d of the eighth spring piece 6d. Exemplarily, the fourth SMA wire 5b is parallel to the extension direction of the second rotation axis P2, that is, the Y-axis direction.
[0292] like Fig.28 As shown, the second fixed end 62c of the seventh reed 6c is fixed to the third protrusion 277 of the second bracket 22a. The second fixed end 62d of the eighth reed 6d is fixed to the fourth protrusion 278 of the second bracket 22a.
[0293] like Fig.29 As shown, when the fourth SMA wire 5b is energized, the fourth SMA wire 5b contracts. On the one hand, the first end of the fourth SMA wire 5b applies a pulling force along the negative direction of the Y axis to the electrical connection end 63c of the seventh spring leaf 6c. The first fixed end 61c of the seventh spring leaf 6c is subjected to the fifth force component along the negative direction of the Y axis and the sixth force component along the negative direction of the Z axis. On the other hand, the second end of the fourth SMA wire 5b applies a pulling force along the positive direction of the Y axis to the electrical connection end 63d of the eighth spring leaf 6d. The first fixed end 61d of the eighth spring leaf 6d is subjected to the seventh force component along the positive direction of the Y axis and the eighth force component along the negative direction of the Z axis. The fifth force component and the seventh force component can be roughly offset. Under the action of the sixth force component and the eighth force component, the camera subject 1 can be moved through the third rotating shaft 259a (see Fig.25 ) and the fourth rotating shaft 259b (see Fig.25 ) rotates clockwise relative to the second carrier 22.
[0294] The following describes a method for controlling the camera body 1 to rotate through the third rotating shaft 259a (see Fig.25 ) and the fourth rotating shaft 259b (see Fig.25 ) is a specific implementation method of rotating relative to the second carrier 22.
[0295] In one embodiment, the third SMA wire 5a and the fourth SMA wire 5b are energized to the maximum current at the same time, and the third SMA wire 5a and the fourth SMA wire 5b are contracted. On the one hand, the first end of the third SMA wire 5a applies a pulling force along the positive direction of the Y axis 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 component force along the positive direction of the Y axis and a second component force along the negative direction of the Z axis. On the other hand, the second end of the third SMA wire 5a applies a pulling force along the negative direction of the Y axis 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 component force along the negative direction of the Y axis and a fourth component force along the negative direction of the Z axis. On the other hand, the first end of the fourth SMA wire 5b applies a pulling force along the negative direction of the Y axis 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 component force along the negative direction of the Y axis and a sixth component force along the negative direction of the Z axis. On the other hand, the second end of the fourth SMA wire 5b applies a pulling force along the positive direction of the Y axis to the electrical connection end 63d of the eighth spring leaf 6d. The first fixed end 61d of the eighth spring leaf 6d is subjected to the seventh force component along the positive direction of the Y axis and the eighth force component along the negative direction of the Z axis. Among them, the first force component and the third force component can be roughly offset. The fifth force component and the seventh force component can be roughly offset. In addition, the resultant force of the second force component and the fourth force component can be roughly offset by the resultant force of the sixth force component and the eighth force component. At this time, the camera subject 1 can be in a balanced state.
[0296] When the current on the third SMA wire 5a is controlled to be greater than the current on the fourth SMA wire 5b (i.e., the current on the fourth SMA wire 5b is reduced), the resultant force of the second force component and the fourth force component is greater than the resultant force of the sixth force component and the eighth force component. Fig.25 ) and the fourth rotating shaft 259b (see Fig.25 ) rotates clockwise relative to the second carrier 22.
[0297] When the current on the third SMA wire 5a is controlled to be smaller than the current on the fourth SMA wire 5b (i.e., the current on the third SMA wire 5a is reduced), the combined force of the sixth force component and the eighth force component is greater than the combined force of the second force component and the fourth force component. Fig.25 ) and the fourth rotating shaft 259b (see Fig.25 ) rotates counterclockwise relative to the second carrier 22.
[0298] 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°.
[0299] Exemplarily, the first carrier 21 drives the camera body 1 to rotate relative to the second carrier 22 around the second rotation axis at an angle ranging from 1° to 4°.
[0300] It is understandable that, as mentioned above, by setting the thickness of the first reed 4a in each section, the shape of each section, and the bending angle of each section, a first reed 4a capable of obtaining a suitable magnification can be set, thereby ensuring that the camera subject 1 is stable during the rotation process, the anti-shake accuracy is better, and the rotation angle of the camera subject 1 is not small, and the anti-shake effect is better. Similarly, the structural settings of the fifth reed 6a, the sixth reed 6b, the seventh reed 6c, and the eighth reed 6d are similar to the structural settings of the first reed 4a. The details are not repeated here.
[0301] It is understandable that each of the above embodiments describes that the gimbal module 2 drives the lens assembly 11 to rotate relative to the first carrier 21 around the first rotation axis P1, and the first carrier 21 drives the lens assembly 11 to rotate relative to the second carrier 22 around the second rotation axis P2. In other embodiments, the gimbal module 2 can also drive the image sensor assembly 12 to rotate relative to the first carrier 21 around the first rotation axis P1, and the first carrier 21 drives the image sensor assembly 12 to rotate relative to the second carrier 22 around the second rotation axis P2. The arrangement between the image sensor assembly 12 and the first carrier 21 can refer to the arrangement between the lens assembly 11 and the first carrier 21. The details are not repeated here.
[0302] It can be understood that the above text specifically introduces a pan / tilt module 2 through the relevant drawings. The first carrier 21 is arranged around the camera body 1, and the camera body 1 rotates around the first rotation axis P1 relative to the first carrier 21, and the second carrier 22 is arranged around the first carrier 21, and the first carrier 21 drives the camera body 1 to rotate around the second rotation axis P2 relative to the second carrier 22. At this time, the camera body 1, the first carrier 21 and the second carrier 22 are roughly arranged in a nested manner.
[0303] It can be understood that the first carrier 21 of this embodiment has the function of "one object for multiple uses". On the one hand, the first carrier 21 can cooperate with the second carrier 22 to serve as a stator for the camera body 1 to rotate around the first rotation axis P1, and on the other hand, the first carrier 21 can serve as a mover for the camera body 1 to rotate around the second rotation axis P2. In this way, the first carrier 21 can play a role of structural reuse, thereby simplifying the structure of the pan-tilt module 2, thereby realizing a miniaturized setting of the pan-tilt module 2.
[0304] In addition, the second carrier 22 of the present 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 subject 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 subject 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 driving mechanism 23 and the second driving mechanism 24 of the gimbal module 2. In this way, the second carrier 22 can play a role of structural reuse, thereby simplifying the structure of the gimbal module 2, thereby realizing the miniaturization setting of the gimbal module 2.
[0305] It can be understood that the second carrier 22 can be used 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 a shell or a middle frame) of the electronic device 1000. In this way, compared with the traditional camera module solution: a shell needs to be set 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 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 a shell or a 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 realizing 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 the cost investment.
[0306] In this embodiment, by setting 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.
[0307] 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 allowed to rotate 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.
[0308] An implementation of the assembly steps of the first carrier 21 , the second carrier 22 , and the second driving mechanism 24 is described below.
[0309] like Fig. 22 and Fig.23 As shown, the second carrier 22 is inverted, 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.
[0310] like Fig. 27 and Fig.29 As shown, the first fixed end 61a of the fifth spring piece 6a, the first fixed end 61b of the sixth spring piece 6b, the first fixed end 61c of the seventh spring piece 6c, and the first fixed end 61d of the eighth spring piece 6d are respectively fixed at different positions of the first carrier 21, and the electrical connection end 63a of the fifth spring piece 6a is arranged opposite to the electrical connection end 63b of the sixth spring piece 6b. The first fixed end 61a of the fifth spring piece 6a is located on the side of the electrical connection end 63a of the fifth spring piece 6a away from the sixth spring piece 6b. The first fixed end 61b of the sixth spring piece 6b is located on the side of the electrical connection end 63b of the sixth spring piece 6b away from the fifth spring piece 6a. The electrical connection end 63c of the seventh spring piece 6c is arranged opposite to the electrical connection end 63d of the eighth spring piece 6d. The first fixed end 61c of the seventh spring piece 6c is located on the side of the electrical connection end 63c of the seventh spring piece 6c away from the eighth spring piece 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.
[0311] like Fig. 27 and Fig.29 As shown, the third SMA wire 5a is electrically connected between the electrical connection end 63a of the fifth reed 6a and the electrical connection end 63b of the sixth reed 6b, and the fourth SMA wire 5b is electrically connected between the electrical connection end 63c of the seventh reed 6c and the electrical connection end 63a of the eighth reed 6d.
[0312] like Fig.25As shown, the assembled structure of 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.
[0313] 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. Exemplarily, the third fixing member 22b can be fixed to the second bracket 22a by a glue dispensing process.
[0314] 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. Exemplarily, the fourth fixing member 22c can be fixed to the second bracket 22a by a glue dispensing process.
[0315] The second fixing ends 62a of the fifth reed 6a, the sixth reed 6b, the seventh reed 6c and the eighth reed 6d are fixed at different positions of the second carrier 22 respectively.
[0316] It is understandable that after the camera module 100 is assembled, the camera module 100 can be assembled 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 Figure 1 and Figure 2 ) so that the camera module 100 is connected to the structural parts of the electronic device 1000.
[0317] The gimbal module 2 mentioned above can control the camera subject 1 to rotate around the first rotation axis P1, and can also control the camera subject 1 to rotate around the second rotation axis P2, so as to realize the optical image stabilization of the camera module and improve the imaging quality of the camera module. The first rotation axis P1 intersects with the second rotation axis P2. It can be understood that the anti-shake of the camera subject 1 controlled by the gimbal module 2 can be anti-shake of large angle and low frequency. For example, the anti-shake angle of the gimbal module 2 of this embodiment is greater than 0.8°, and the frequency is less than 4Hz. The following will introduce an anti-shake motor in an image sensor assembly 12 in conjunction with the relevant drawings. The anti-shake motor controls the movement of the image sensor 122 on the XY plane to realize the optical image stabilization of the camera module 100 and improve the imaging quality of the camera module 100. It can be understood that the anti-shake of the image sensor 122 controlled by the anti-shake motor can be anti-shake of small angle and high frequency. For example, the anti-shake angle of the anti-shake motor is less than 0.8°, and the frequency is greater than 4Hz.
[0318] 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 drive the image sensor to move. 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 current in the coil, thereby controlling the displacement amount and direction of the image sensor on each axis.
[0319] Specifically, coils are arranged on the first side, the second side and the third side of the image sensor. The coils on the first side, the second side and the third side are used to push the image sensor to move along the X-axis, Y-axis and R-axis directions to achieve three-axis optical image stabilization.
[0320] In the optical image stabilization motor, the number of coils on each side, the coil setting position on each side, and the coil size can be set according to actual needs and are not limited here.
[0321] In one embodiment, a three-coil electromagnetic drive scheme.
[0322] Under the three-coil electromagnetic driving scheme, the optical image stabilization motor may include a first coil, a second coil and a third coil.
[0323] 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, that is, 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, and the third side is adjacent to the first side and the second side.
[0324] The driving chip outputs a first current signal through a current generating structure (e.g., a PWM driving structure) according to 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, so as to apply a force along the X-axis direction to the image sensor, thereby driving the image sensor to translate along the X-axis direction.
[0325] The driving chip outputs a second current signal through a current generating structure (e.g., a PWM driving structure) according to 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, so as to apply a torque along the R-axis to the image sensor, thereby driving the image sensor to rotate along the R-axis.
[0326] The driving chip outputs a third current signal through a current generating structure (e.g., a PWM driving structure) according to 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, so as to apply a force along the Y-axis direction to the image sensor, thereby driving the image sensor to translate along the Y-axis.
[0327] In some embodiments, in order to further reduce crosstalk and reduce crosstalk compensation in drive control, in the mechanical structure design, the mechanical center can be made to coincide 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 direction and the force along the Y-axis direction generated by the third coil.
[0328] At this time, 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 pass through the geometric center of the image sensor, and the normal line passing through the center of the third coil passes through the geometric center of the image sensor. In addition, the center of gravity and the geometric center of the image sensor coincide. Of course, in other embodiments, if "multiple centers in one" are 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 the image sensor is pushed to move along each axis, more crosstalk will be generated, and the control algorithm needs to make more crosstalk compensation. The control algorithm needs to make more crosstalk compensation, which will reduce the real-time performance of the optical image stabilization compensation control.
[0329] For example, see Fig.30 The schematic diagram of the three-coil electromagnetic drive scheme is shown. 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 to push the image sensor 93 to move on the X-axis, Y-axis and R-axis.
[0330] 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. Fig.30 In the embodiment of the present application, the magnetization direction of the magnet can be a uniform magnetization of four poles, or two identical magnets can be connected together after bipolar magnetization. Fig.30 As shown in the figure, two magnets with N poles and S poles are connected together. When the coil is energized, a leftward Lorentz force F is generated in the magnetic field of the two magnets. Of course, the magnetization direction can also be different from Fig.30 To the contrary, this is not intended to be limiting.
[0331] like Fig.30 As shown, 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 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 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 direction. x .
[0332] exist Fig.30 In the figure, 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 .
[0333] The Lorentz force generated by the coil 95 in the magnetic field after being energized does not coincide with the center O of the image sensor 93, and there is a force arm, thus generating a torque on the image sensor 93. Under the action of the torque, the image sensor 93 can rotate along the R axis in the XY plane. Fig.30 In the figure, the image sensor 93 rotates counterclockwise in the XY plane under the action of the torque.
[0334] in addition, Fig.30 Also shown are high-precision position sensors 91, 94, and 97. Position sensor 91 is placed in the middle area of coil 92, position sensor 94 is placed in the middle area of coil 95, and position sensor 97 is placed in the middle area of coil 96.
[0335] Position sensor 91 is used in combination with magnet 99a to detect the position of the image sensor. Position sensor 94 is used in combination with magnet 98 to detect the position of the image sensor. Position sensor 97 is used in combination 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.
[0336] Understandably, Fig.30The diagram 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 magnet 98, magnet 99a and magnet 99b are front views viewed from the negative direction of the Y axis to the positive direction of the Y axis. The diagram of the magnet including the N pole and the S pole is a side view viewed from the positive direction of the X axis to the negative direction of the X axis.
[0337] It can be seen that the three-axis decoupled negative feedback of pitch, yaw and roll is realized through position sensor 91, position sensor 94 and position sensor 97.
[0338] Based on the decoupling negative feedback of pitch, yaw and roll, the mutual decoupling of the three-axis drive control is achieved.
[0339] It is understandable 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 above content. Fig.30 The three-coil electromagnetic drive scheme shown can be replaced by three coils 96 and three coils 95 to obtain a seven-coil electromagnetic drive scheme. Fig.30 The three-coil electromagnetic driving scheme shown can be replaced by three coils in place of coil 96 , three coils in place of coil 95 , and three coils in place of coil 92 to obtain a nine-coil electromagnetic driving scheme.
[0340] In the embodiment of the present application, different coil sizes, coil numbers, and coil positions can result in different electromagnetic drive schemes. The drive control logic of different electromagnetic drive schemes is similar, and the driver chip applies currents of corresponding magnitudes and directions to the corresponding coils according to the displacement and displacement direction of the image sensor on each axis, thereby generating a Lorentz force acting on the image sensor to drive the image sensor to move in all directions for jitter compensation. The difference is that the electromagnetic drive scheme with a larger number of coils will have a greater electromagnetic drive force and better drive stability.
[0341] 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.
[0342] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of the present application. In other words, the multiple embodiments described above can also be arbitrarily combined according to actual needs.
[0343] It should be noted that all the above drawings are illustrative illustrations of the present application and do not represent the actual size of the product. Moreover, the size ratio relationship between the components in the drawings is not intended to limit the actual product of the present application.
[0344] The above are only some embodiments and implementation methods of the present application, and the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
