Description

Technical Field

[0001] This application relates to the field of camera technology, and in particular to a camera module and electronic device. Background Technology

[0002] With the widespread adoption and development of smartphones, mobile phone photography has become a common way for people to take pictures. Furthermore, phones with both optical image stabilization and autofocus are increasingly popular. Traditional camera modules consist of a gimbal module and the camera body. The gimbal module stabilizes the camera body by controlling its movement perpendicular to the optical axis. However, due to an unreasonable structural design, the camera module is often quite large. Summary of the Invention

[0003] This application provides 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 the image information carried by the light into electrical signals.

[0005] The first carrier is arranged around the camera body, 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 relative to the second carrier around the second rotation axis. The extension direction of the first rotation axis and the extension direction of the second rotation axis intersect each other with the optical axis direction of the camera module.

[0008] Understandably, when the camera module is collecting light, if the electronic device shakes due to external forces, the shaking motion of the camera body can be counteracted by controlling the camera body to rotate around a first rotation axis and / or around a second rotation axis, thereby avoiding or reducing the positional offset of the camera body caused by shaking. In other words, the camera module of this application can control the camera body to rotate around a first rotation axis and / or around a second rotation axis through a gimbal module, achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0009] In this embodiment, by setting a first carrier around the camera body and a second carrier around the first carrier, the camera body, the first carrier, and the second carrier are arranged in a roughly nested manner.

[0010] It is understandable that the first carrier in this embodiment has a "multi-purpose" function. 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. 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 in structural reuse, thereby simplifying the structure of the gimbal module and realizing the miniaturization of the gimbal module.

[0011] Furthermore, the second carrier in this embodiment also has a "multi-purpose" function. The second carrier can cooperate with the first carrier to serve as a stator for the camera body to rotate around the first rotation axis; alternatively, the second carrier can serve as a stator for the camera body to rotate around the second rotation axis. Thus, the second carrier can function as a stator for components of the camera module. Moreover, the second carrier can be arranged around the first carrier, and it serves to protect the first carrier, the first drive mechanism, and the second drive mechanism of the gimbal module. In this way, the second carrier can achieve structural reuse, thereby simplifying the structure of the gimbal module and enabling its miniaturization.

[0012] Understandably, the second carrier can serve as both the stator for the camera module components and protect the first carrier, first drive mechanism, and second drive mechanism of the gimbal module. Thus, when the camera module is applied to an electronic device, the second carrier of the gimbal module can be directly fixed to the structural components (e.g., housing or mid-frame) of the electronic device. This is significantly different from traditional camera module solutions, where the gimbal module requires an outer casing to encapsulate and fix it to the structural components (e.g., housing or mid-frame) of the electronic device. In this embodiment, since the second carrier of the gimbal module can be directly fixed to the structural components (e.g., housing or mid-frame) of the electronic device, the camera module does not need an additional outer casing, further simplifying its structure and facilitating miniaturization. Furthermore, the step of fixing the camera module to the structural components (e.g., housing or mid-frame) of the electronic device via an outer casing is eliminated, reducing costs.

[0013] In one possible implementation, the camera body includes a lens assembly and an image sensor assembly, the image sensor assembly being fixed to the light-emitting side of the lens assembly; the first carrier is disposed around the lens assembly, and the lens assembly is rotatably connected to the first carrier.

[0014] In one possible implementation, the camera body includes a first side and a second side disposed opposite to each other, and the first carrier includes a first side and a second side disposed opposite to each other;

[0015] The first side of the first carrier is opposite to and spaced apart from the first side of the camera body, and the first side of the first carrier is rotatably connected to the first side of the camera body through a first rotating shaft;

[0016] The second side of the first carrier is opposite to and spaced apart from the second side of the camera body. The second side of the first carrier is rotatably connected to the second side of the camera body via a second rotating shaft. The extension of the center line of the first rotating shaft or the extension of the center line of the second rotating shaft constitutes the first rotation axis. The first rotating shaft and the second rotating shaft can be collinear.

[0017] In one possible implementation, the camera body includes a third side portion connected between the first side portion and the second side portion, the first carrier includes a third edge portion connected between the first edge portion and the second edge portion of the first carrier, and the third edge portion of the first carrier is opposite to and spaced apart from the third side portion of the camera body.

[0018] The first drive mechanism includes a first reed, a second reed, and a first SMA wire;

[0019] The first spring includes a first fixed end, an electrical connection end, and a second fixed end connected in sequence. The first fixed end of the first spring is fixed to the third side of the camera body, and the second fixed end of the first spring is fixed to the third side of the first carrier.

[0020] In the optical axis direction of the camera module, there is a height difference between the electrical connection end of the first spring and the first fixed end; in the extension direction of the first rotation axis, there is a distance between the electrical connection end of the first spring and the first fixed end.

[0021] The second spring includes a first fixed end, an electrical connection end, and a second fixed end connected in sequence. The first fixed end of the second spring is fixed to the third side of the camera body, and the second fixed end of the second spring is fixed to the third side of the first carrier. The electrical connection end of the second spring is spaced apart from the electrical connection end of the first spring and is located between the first fixed end of the second spring and the first fixed end of the first spring.

[0022] In the optical axis direction of the camera module, there is a height difference between the electrical connection end of the second spring and the first fixed end; in the extension direction of the first rotation axis, there is a distance between the electrical connection end of the second spring and the first fixed end.

[0023] The first SMA wire is electrically connected to the electrical connection terminal of the second spring and the electrical connection terminal of the first spring.

[0024] In one possible implementation, the third side of the camera body includes a first sub-side, a second sub-side, and a third sub-side connected in sequence. The first sub-side is connected to the first side, and the third sub-side is connected to the second side. The included angle between the first sub-side and the second sub-side, and the included angle between the second sub-side and the third sub-side, are both obtuse angles.

[0025] The third side of the first carrier includes a first sub-side, a second sub-side, and a third sub-side connected in sequence. The first sub-side is connected to the first side of the first carrier, and the third sub-side is connected to the second side of the first carrier. The included angle between the first sub-side and the second sub-side, and the included angle between the second sub-side and the third sub-side, are both obtuse angles.

[0026] The first sub-side portion of the first carrier is opposite to and spaced apart from the first sub-side portion of the camera body; the second sub-side portion of the first carrier is opposite to and spaced apart from the second sub-side portion of the camera body; and the third sub-side portion of the first carrier is opposite to and spaced apart from the third sub-side portion of the camera body.

[0028] It is understandable that, through the above settings, the distance between the first fixed end of the first spring and the second fixed end of the first spring in the direction of extension of the first rotation axis, as well as the distance between the first fixed end of the second spring and the second fixed end of the second spring in the direction of extension of the first rotation axis, can be reduced. This ensures that the rotation angle of the camera body remains unchanged while reducing the distance that the first fixed end of the first spring moves along the optical axis of the camera module, thereby reducing the power consumption of the first SMA line.

[0029] In one possible implementation, the first reed includes a first segment, a second segment, and a third segment connected in sequence, wherein the end of the first segment away from the second segment is a first fixed end. The end of the third segment away from the second segment is a second fixed end. At least a portion of the second segment is an electrical connection end;

[0032] It is understandable that, through the above settings, the distance between the first fixed end of the first spring and the second fixed end of the first spring in the extension direction of the first rotation axis can be reduced, thereby ensuring that the rotation angle of the camera body remains unchanged, while reducing the distance that the first fixed end of the first spring moves along the optical axis of the camera module, thereby reducing the power consumption of the first SMA line.

[0033] In one possible implementation, the camera body includes a fourth side portion connected between the first side portion and the second side portion, the fourth side portion being located on the side of the first rotation axis away from the third side portion;

[0034] The first carrier includes a fourth side portion, which is connected between the first side portion and the second side portion of the first carrier. The fourth side portion of the first carrier is opposite to and spaced apart from the fourth side portion of the camera body.

[0035] The first drive mechanism includes a third reed, a fourth reed, and a second SMA wire;

[0036] The third spring includes a first fixed end, an electrical connection end, and a second fixed end connected in sequence. The first fixed end of the third spring is fixed to the fourth side of the camera body, and the second fixed end of the third spring is fixed to the fourth side of the first carrier.

[0037] In the optical axis direction of the camera module, there is a height difference between the electrical connection end of the third spring and the first fixed end; in the extension direction of the first rotation axis, there is a distance between the electrical connection end of the third spring and the first fixed end.

[0038] The fourth spring includes a first fixed end, an electrical connection end, and a second fixed end connected in sequence. The first fixed end of the fourth spring is fixed to the fourth side of the camera body, and the second fixed end of the fourth spring is fixed to the fourth side of the first carrier. The electrical connection end of the fourth spring is spaced apart from the electrical connection end of the third spring and is located between the first fixed end of the fourth spring and the first fixed end of the third spring.

[0039] In the optical axis direction of the camera module, there is a height difference between the electrical connection end of the fourth reed and the first fixed end; in the extension direction of the first rotation axis, there is a distance between the electrical connection end of the fourth reed and the first fixed end.

[0040] The second SMA wire is electrically connected to the electrical connection terminal of the third spring and the electrical connection terminal of the fourth spring.

[0041] In one possible implementation, the fourth side of the camera body includes a fourth sub-side, a fifth sub-side, and a sixth sub-side connected in sequence. The fourth sub-side is connected to the second side, and the sixth sub-side is connected to the first side. The angle between the fourth sub-side and the fifth sub-side, and the angle between the fifth sub-side and the sixth sub-side, are both obtuse angles.

[0042] The fourth side of the first carrier includes a fourth sub-side, a fifth sub-side, and a sixth sub-side connected in sequence. The fourth sub-side is connected to the first side, and the sixth sub-side is connected to the first side. The included angle between the fourth sub-side and the fifth sub-side, and the included angle between the fifth sub-side and the sixth sub-side, are both obtuse angles.

[0043] The fourth sub-side of the first carrier is opposite to and spaced apart from the fourth sub-side of the camera body; the fifth sub-side of the first carrier is opposite to and spaced apart from the fifth sub-side of the camera body; and the sixth sub-side of the first carrier is opposite to and spaced apart from the sixth sub-side of the camera body.

[0045] It is understandable that, through the above settings, the distance between the first fixed end of the third spring and the second fixed end of the third spring in the extension direction of the first rotation axis, as well as the distance between the first fixed end of the fourth spring and the second fixed end of the fourth spring in the extension direction of the first rotation axis, can be reduced. This ensures that the rotation angle of the camera body remains unchanged while reducing the distance that the first fixed end of the first spring moves along the optical axis of the camera module, thereby reducing the power consumption of the first SMA line.

[0046] In one possible implementation, the first rotating shaft and the first side of the camera body are integrally formed, and the second rotating shaft and the second side of the camera body are integrally formed.

[0047] The first carrier has a first groove on its first side and a second groove on its second side;

[0049] In this embodiment, by setting the first rotating shaft of the lens assembly to cooperate with the first groove of the first bracket, and the second rotating shaft of the lens assembly to cooperate with the second groove of the first bracket, on the one hand, the camera body can rotate relative to the first carrier through the first rotating shaft and the second rotating shaft, and on the other hand, the rotation of the camera body in other directions can be restricted, thereby restricting the degree of freedom of the camera body to rotate around the first rotation axis. In this way, the image stabilization of the camera body is more stable and the image stabilization effect is better.

[0050] In one possible implementation, the first carrier includes a first support and a first fixing member. The first groove is located on a first side of the first support, and the second groove is located on a second side of the first support. The first groove includes a first groove sidewall and a second groove sidewall disposed opposite to each other. The first fixing member is fixed to the first support and covers the first groove. The first fixing member, the first groove sidewall, and the second groove sidewall of the first groove provide three-point support for the first rotating shaft. In this way, the connection stability between the first rotating shaft and the first support is better.

[0051] In one possible implementation, the first carrier includes a second fixing member, which is fixed to the first bracket and covers the second groove. The second fixing member, the first groove sidewall of the second groove, and the second groove sidewall of the second groove provide three-point support for the second rotating shaft. This improves the connection stability between the second rotating shaft and the first bracket.

[0052] It is understandable that by using the first bracket and the first fixing member to support the first rotating shaft at three points, and by using the first bracket and the second fixing member to support the second rotating shaft at three points, the connection stability between the camera body and the first carrier is improved. This also improves the connection stability between the second rotating shaft and the first bracket.

The first fixed end of the fifth reed is fixed to the third side of the first carrier, and the second fixed end of the fifth reed is fixed to the third side of the second carrier.

[0060] In the optical axis direction of the camera module, there is a height difference between the electrical connection end of the sixth reed and the first fixed end; in the extension direction of the second rotation axis, there is a distance between the electrical connection end of the sixth reed and the first fixed end.

[0065] In one possible implementation, the second carrier includes a fourth side portion, which is connected between the first side portion and the second side portion of the second carrier, and the fourth side portion of the second carrier is opposite to and spaced apart from the fourth side portion of the first carrier.

The first fixed end of the seventh reed is fixed to the fourth side of the first carrier, and the second fixed end of the seventh reed is fixed to the fourth side of the second carrier.

[0110] The embodiments of this application are described below with reference to the accompanying drawings.

[0111] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the components can rotate relative to each other after connection. The directional terms mentioned in the embodiments of this application, such as "top," "bottom," "upper," "lower," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the referred device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. "Multiple" refers to at least two. A and / or B include three schemes, specifically scheme A, scheme B, and scheme AB. "Electrical connection" means that electrical signals can be conducted between them. In addition, the integrated structure obtained by the two components through the one-piece molding process means that during the formation of one of the two components, that component is connected to the other component, without the need for further processing (such as bonding, welding, snap-fit ​​connection, screw connection) to connect the two components together.

[0112] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0113] Furthermore, the mathematical concepts mentioned in the embodiments of this application, such as parallel and perpendicular, are limitations specific to the current technological level, rather than absolute and strict mathematical definitions. Slight deviations are permissible; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0114] It is understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0115] Figure 1 This is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of this application.

[0116] like Figure 1 As shown, the electronic device 1000 can be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses or VR helmet, or other devices with camera functions. Figure 1 The electronic device 1000 of the embodiment shown is illustrated using a mobile phone as an example.

[0117] Figure 2 yes Figure 1 A partial cross-sectional view of the electronic device 1000 shown in one embodiment on 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 can be a rear-facing camera module or a front-facing camera module. It should be noted that... Figure 1 The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 As well as the accompanying drawings below. Furthermore, 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 rear cover 202. The rear cover 202 is fixed to the frame 201. For example, the rear cover 202 can be fixedly connected to the frame 201 by adhesive. The rear cover 202 may also be integrally formed with the frame 201, that is, the rear cover 202 and the frame 201 are a single structure.

[0120] In one embodiment, the screen 300 can be located on the side of the bezel 201 away from the back cover 202. In this case, the screen 300 and the back cover 202 can be located on opposite sides of the bezel 201. The screen 300, bezel 201, and back cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, receiver, or microphone. The screen 300 can 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 rear cover 202. The rear cover 202 may have a light-transmitting hole 203. The shape of the light-transmitting hole 203 is not limited to the following. Figure 1 The schematic diagram shows a circle. The light-transmitting hole 203 connects the interior of the electronic device 1000 to the exterior. Light from outside the electronic device 1000 can enter the interior through the light-transmitting hole 203. The camera module 100 can capture the light entering the interior of the electronic device 1000.

[0122] For example, the camera module 100 can be a conventional camera module (i.e., the optical axis of the camera module 100 is in the Z-axis direction). In some embodiments, the camera module 100 can also be a periscope camera module (i.e., the optical axis of the camera module 100 is in any direction on the XY plane). It is understood that the camera module 100 in this embodiment is described using a conventional 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 defined as the Y-axis. The thickness direction of the camera module 100 is defined as the Z-axis. It is understood that the coordinate system of the camera module 100 can be flexibly set according to specific practical needs. In this embodiment, the X-axis direction is used as the first direction, the Y-axis direction as the second direction, and the Z-axis direction as the third direction for description.

[0124] Figure 3 yes Figure 1 A schematic diagram of one embodiment of the camera module 100 shown. Figure 4 yes Figure 3 A partially exploded view of one embodiment of the camera module 100 shown.

[0125] like Figure 3 and Figure 4 As shown, the camera module 100 may include a camera body 1 and a gimbal module 2. The camera body 1 is mounted on the gimbal module 2.

[0126] For example, the camera body 1 is used to collect light and convert the image information carried by the light into electrical signals.

[0127] For example, the gimbal module 2 can control the camera body 1 to rotate around a first rotation axis P1, and can also control the camera body 1 to rotate around a second rotation axis P2. The extension directions of the first rotation axis P1 and the second rotation axis P2 intersect each other with the optical axis direction of the camera module 100. It can be understood that the first rotation axis P1 and the second rotation axis P2 can be extensions of physical axes or extensions of virtual axes.

[0128] For example, the extension direction of the first rotation axis P1 can be the X-axis direction. The extension direction of the second rotation axis P2 can be the Y-axis direction. The optical axis direction of the camera module 100 is the Z-axis direction. It is understood that the gimbal module 2 can independently control the camera body 1 to rotate around the first rotation axis P1, independently control the camera body 1 to rotate around the second rotation axis P2, or simultaneously control the camera body 1 to rotate around both the first and second rotation axes P1. For example, when the gimbal module 2 independently controls the camera body 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 body 1 can rotate along a plane perpendicular to the X-axis direction (i.e., the YZ plane). When the gimbal module 2 independently controls the camera body 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 body 1 can rotate along a plane perpendicular to the Y-axis direction (i.e., the XZ plane). When the gimbal module 2 simultaneously controls the camera body 1 to rotate around both the first rotation axis P1 and the second rotation axis P2, since the extension direction of the first rotation axis P1 is the X-axis direction and the extension direction of the second rotation axis P2 is the Y-axis direction, the camera body 1 can rotate around both the X-axis and the Y-axis.

[0129] It is understood that the gimbal module 2 can control the camera body 1 to rotate around the X-axis and / or around the Y-axis. When the camera module is collecting light, if the electronic device shakes due to external forces, the gimbal module 2 can control the camera body 1 to rotate around the X-axis and / or around the Y-axis to counteract the shaking stroke of the camera body 1, thereby avoiding or reducing the positional offset of the camera body 1 caused by shaking. In other words, the camera module 100 of this application can control the camera body 1 to rotate around the X-axis and / or around the Y-axis through the gimbal module 2 to achieve optical image stabilization (OIS) of the camera module and improve the imaging quality of the camera module. It is understood that the image stabilization controlled by the gimbal module 2 can be a large-angle and low-frequency image stabilization. For example, the image stabilization angle of the gimbal module 2 in this embodiment is greater than 0.8° and the frequency is less than 4Hz.

[0130] Figure 5 yes Figure 4 The camera body 1 shown is partially exploded in one embodiment. Figure 6 yes Figure 5 The exploded view of the camera subject 1 from another angle.

[0131] Please see Figure 5 and Figure 6 and combined 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 electrical signals.

[0132] It is understood that the camera body 1 may also include more structures. For example, the camera body 1 may also 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 opening of the variable aperture can be automatically adjusted. Light can enter the lens assembly 11 through the aperture opening of the variable aperture.

[0133] like Figure 5 and Figure 6 As shown, the lens assembly 11 includes a first housing 11a and a focusing lens 11b. The focusing lens 11b is movable along the Z-axis to achieve autofocus (AF). The first housing 11a has a first through-hole 11c. The first through-hole 11c connects the interior and exterior of the first housing 11a. The focusing lens 11b is mounted inside the first housing 11a, and a portion of the focusing lens 11b protrudes outside the first housing 11a through the first through-hole 11c.

[0134] It is understood that the structures of the first housing 11a and the focusing lens 11b can both adopt conventional structures for the first housing and the focusing lens, and this application does not impose any specific limitations. Furthermore, the lens assembly 11 may include more or fewer structures. For example, when the lens assembly 11 does not include the focusing lens 11b, then the lens assembly 11 includes a fixed-focus lens.

[0135] like Figure 5 and Figure 6 As shown, exemplarily, 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 disposed opposite to each other, and a fourth side portion 114. 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] For example, the second sub-side 1132 includes a first sub-side 1131, a second sub-side 1132, and a third sub-side 1133 connected in sequence. The first sub-side 1131 is connected to the first side 111. The third sub-side 1133 is connected to the second side 112.

[0137] For example, the included angle between the first sub-side 1131 and the second sub-side 1132, and the included angle between the second sub-side 1132 and the third sub-side 1133 are both obtuse angles.

[0138] For example, the fourth side 114 includes a fourth sub-side 1141, a fifth sub-side 1142, and a sixth sub-side 1143 connected in sequence. The fourth sub-side 1141 is connected to the second side 112. The sixth sub-side 1143 is connected to the first side 111.

[0139] For example, the included angle between the fourth sub-side 1141 and the fifth sub-side 1142, and the included angle between the fifth sub-side 1142 and the sixth sub-side 1143 are both obtuse angles.

[0140] For example, the first housing 11a has an approximately octagonal shape in cross-section parallel to the XY plane.

[0141] The first outer casing 11a also includes a first rotating shaft 111a and a second rotating shaft 111b. The first rotating shaft 111a and the second rotating shaft 111b can be on the same straight line, that is, the first rotating shaft 111a and the second rotating shaft 111b are collinear. The first rotating shaft 111a and the second rotating shaft 111b protrude from the outer surface of the first outer casing 11a. The extension of the center line of the first rotating shaft 111a or the extension of the center line of the second rotating shaft 111b can constitute the first rotation axis P1. It is understood that the first outer casing 11a and the first rotating shaft 111a can be integrally formed. The first outer casing 11a and the second rotating shaft 111b can be integrally formed.

[0142] For example, a first rotating shaft 111a protrudes from a first side 111 of a first housing 11a. A second rotating shaft 111b protrudes from a second side 112 of a 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 the image sensor assembly 12 at the BB line.

[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 and electrically connected to the module circuit board 121. In this case, 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 has a light-transmitting hole 125. The filter 124 is fixedly connected to the filter holder 123. The filter 124 can be located within the light-transmitting hole 125. The filter 124 is also disposed opposite to the image sensor 122. The filter 124 can be used to filter infrared light or blue light, etc., from the light entering the image sensor 122, thereby ensuring that the image sensor 122 has better imaging quality.

[0145] like Figure 6 and Figure 7 As shown, when the image sensor assembly 12 is fixed to the light-emitting side of the lens assembly 11, the image sensor 122, the filter 124, and the focusing lens 11b are arranged sequentially in the Z-axis direction. At this time, the image sensor 122 is located on the light-emitting side of the focusing lens 11b. The filter 124 is located between the focusing 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 to the module circuit board 121 or to the filter holder 123. The image sensor 122, the filter holder 123, and the filter 124 can be located inside the second housing 126. The second housing 126 can be used to protect the image sensor 122, the filter holder 123, and the filter 124. In addition, the second housing 126 is provided with a second through hole 127, which connects the interior and exterior of the second housing 126. The first housing 11a of the lens assembly 11 can be fixed to the second housing 126 by adhesive or the like. In the Z-axis direction, the focusing lens 11b can be disposed opposite to the filter 124 and the image sensor 122 through the second through hole 127 of the second housing 126.

[0147] It is understood that the image sensor assembly 12 may also include a stabilization motor (not shown). The stabilization motor can be fixed to the module circuit board 121. The stabilization motor is used to control the movement of the image sensor 122 along a plane perpendicular to the third direction Z (i.e., the XY plane). Thus, when the camera module 100 collects ambient light, if the electronic device 1000 experiences shaking in the XY plane due to external forces, the stabilization motor can control the movement of the image sensor 122 in the XY plane to counteract the shaking travel of the focusing lens 11b in the XY plane, thereby avoiding or reducing the positional offset of the focusing lens 11b caused by shaking. In other words, the camera module 100 of this application can control the movement of the image sensor 122 in the XY plane through the stabilization motor to achieve optical image stabilization (OIS) of the camera module 100, improving the imaging quality of the camera module 100. It is understood that the stabilization of the image sensor 122 controlled by the stabilization motor can be a small-angle and high-frequency stabilization. For example, the stabilization motor has a stabilization angle of less than 0.8° and a frequency greater than 4Hz. The structure of the stabilization motor will be described in detail later with reference to the accompanying diagrams.

[0148] The above text, with reference to the accompanying drawings, details the structure of the camera module 100 and its main camera body 1. The following text, with reference to the accompanying drawings, details the structure of the gimbal module 2 and its connection to the main camera body 1.

[0149] Figure 8 yes Figure 4 The gimbal module 2 shown is partially exploded in one embodiment.

[0150] like Figure 8 As shown, the gimbal module 2 includes a first carrier 21, a second carrier 22, a first drive mechanism 23, and a second drive mechanism 24.

[0151] Figure 9 yes Figure 8 The first carrier 21 shown is partially exploded in one embodiment. Figure 10 yes Figure 9 The first carrier 21 shown is partially exploded from another angle. Figure 11 yes Figure 9 The first carrier 21 shown is partially exploded from another angle.

[0152] like Figures 9 to 11 As shown, the first carrier 21 includes a first support 21a, a first fixing member 21b, and a second fixing member 21c.

[0153] For example, the first bracket 21a includes a first side 211 and a second side 212 disposed opposite to each other, and a third side 213 and a fourth side 214 disposed opposite to each other.

[0154] For example, the third side 213 of the first bracket 21a includes a first sub-side 2131, a second sub-side 2132 and a third sub-side 2133 connected in sequence. The first sub-side 2131 is connected to the first side 211 of the first bracket 21a and the third sub-side 2133 is connected to the second side 212 of the first bracket 21a.

[0155] For example, the included angle between the first sub-side 2131 and the second sub-side 2132, and the included angle between the second sub-side 2132 and the third sub-side 2133 are both obtuse angles.

[0156] For example, 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] For example, the angle between the fourth sub-side 2141 and the fifth sub-side 2142, and the angle between the fifth sub-side 2142 and the sixth sub-side 2143 are both obtuse angles.

[0158] For example, the first support 21a has an approximately octagonal shape in its cross-section parallel to the XY plane.

[0159] It is understood that the first support 21a may include fewer or more structures. For example, when the first support 21a includes fewer structures, the shape of its cross-section parallel to the XY plane may be quadrilateral, pentagonal, hexagonal, or heptagonal. When the first support 21a includes more structures, the shape of its cross-section parallel to the XY plane may be n-sided, where n is greater than 8.

[0160] For example, the angle between two adjacent sides is 135°. In this case, the first support 21a is approximately 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 disposed opposite to each other. The first groove 251 and the second groove 252 form openings on the inner surface and bottom surface of the first bracket 21a.

[0162] For example, the first groove 251 is located at the first side 211 of the first bracket 21a. The second groove 252 is located at the second side 212 of the first bracket 21a.

[0163] For example, the first groove 251 includes a first groove sidewall 253 and a second groove sidewall 254 disposed opposite to each other. The angle between the first groove sidewall 253 and the second groove sidewall 254 of the first groove 251 is an acute angle.

[0164] It is understandable that the second groove 252 has a similar or identical configuration to the first groove 251.

[0165] like Figure 11 As shown, the first bracket 21a is also provided with a first protrusion 255 and a second protrusion 256. The first protrusion 255 and the second protrusion 256 protrude from the inner surface of the first bracket 21a.

[0166] For example, the first protrusion 255 and the second protrusion 256 protrude from the inner surface of the second sub-side 2132 of the third side 213.

[0167] Understandably, although Figure 11 The illustration shows that the first protrusion 255 and the second protrusion 256 are spaced apart, but the first protrusion 255 can also be connected to the second protrusion 256, in which case the first protrusion 255 and the second protrusion 256 form a protrusion.

[0168] like Figure 9 and Figure 10 As shown, the first bracket 21a is also provided with a third protrusion 257 and a fourth protrusion 258. The third protrusion 257 and the fourth protrusion 258 protrude from the inner surface of the first bracket 21a.

[0169] For example, the third protrusion 257 and the fourth protrusion 258 protrude from the inner surface of the fifth sub-side 2142 of the fourth side 214.

[0170] Understandably, although Figure 9 and Figure 10 The diagram shows that the third protrusion 257 and the fourth protrusion 258 are spaced apart, but the third protrusion 257 can also be connected to the fourth protrusion 258, in which case the third protrusion 257 and the fourth protrusion 258 form a protrusion.

[0171] like Figures 9 to 11 As shown, the first support 21a also includes a third rotating shaft 259a and a fourth rotating shaft 259b. The third rotating shaft 259a and the fourth rotating shaft 259b can be on the same straight line, that is, the third rotating shaft 259a and the fourth rotating shaft 259b are collinear. The third rotating shaft 259a and the fourth rotating shaft 259b protrude from the outer surface of the first support 21a. The extension of the center line of the third rotating shaft 259a or the extension of the center line of the fourth rotating shaft 259b can form the second rotation axis P2.

[0172] For example, the third pivot 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 pivot 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 pivot 259a and the fourth pivot 259b may be parallel to the Y-axis direction.

[0173] For example, both the third shaft 259a and the fourth shaft 259b are cylindrical.

[0174] For example, the third rotating shaft 259a and the first support 21a can be an integrally formed structure. The fourth rotating shaft 259b and the first support 21a can be an integrally formed structure.

[0175] Figure 12 yes Figure 3 The diagram shows a partial structural schematic of the camera module 100 in one embodiment.

[0176] like Figure 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. For example, the first bracket 21a can be arranged around the lens assembly 11 of the camera body 1.

[0177] Exemplarily, a first side portion 111 of the first housing 11a of the lens assembly 11 is opposite to and spaced apart from a first edge portion 211 of the first bracket 21a. A second side portion 112 of the first housing 11a of the lens assembly 11 is opposite to and spaced apart from a second edge portion 212 of the first bracket 21a. A first sub-side portion 1131 of the first housing 11a of the lens assembly 11 is opposite to and spaced apart from a first sub-edge portion 2131 of the first bracket 21a. A second sub-side portion 1132 of the first housing 11a of the lens assembly 11 is opposite to and spaced apart from a second sub-edge portion 2132 of the first bracket 21a. A third sub-side portion 1133 of the first housing 11a of the lens assembly 11 is opposite to and spaced apart from a third sub-edge portion 2133 of the first bracket 21a. A fourth sub-side portion 1141 of the first housing 11a of the lens assembly 11 is opposite to and spaced apart from a fourth sub-edge 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 apart from the fifth sub-side 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 apart from the sixth sub-side portion 2143 of the first bracket 21a.

[0178] Figure 13 yes Figure 12 The image shows a partial cross-sectional view of the camera module 100 along the CC line in one embodiment.

[0179] like Figure 13As shown, at least a portion of the first pivot 111a of the lens assembly 11 is located within the first groove 251 of the first bracket 21a and is rotatably connected to the groove wall of the first groove 251. A 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 pivot 111a from dislodging from the first groove 251.

[0180] It is understood that the first fixing member 21b can be fixed to the bottom surface of the first bracket 21a or fixed within the first groove 251. Furthermore, the first fixing member 21b can cover the entire first groove 251 or only a portion of it.

[0181] For example, the first fastener 21b may be a metal sheet, such as a steel sheet or an aluminum sheet.

[0182] In other embodiments, the positions of the first pivot 111a of the lens assembly 11 and the first groove 251 of the first bracket 21a can be interchanged.

[0183] Figure 14 yes Figure 12 The diagram shows a partial structural schematic of the camera module 100 in one embodiment.

[0184] like Figure 13 and Figure 14 As shown, exemplarily, the first fixing member 21b supports the first rotating shaft 111a. The first fixing member 21b, the first groove sidewall 253 of the first groove 251, and the second groove sidewall 254 of the first groove 251 can roughly form a triangle. In this case, the first fixing member 21b, the first groove sidewall 253 of the first groove 251, and the second groove sidewall 254 of the first groove 251 can provide three-point support for the first rotating shaft 111a. In this way, the connection stability between the first rotating shaft 111a and the first bracket 21a is better.

[0185] like Figure 13 As shown, at least a portion of the second pivot 111b of the lens assembly 11 is located within the second groove 252 of the first bracket 21a and is rotatably connected to the groove wall of the second groove 252. A second fixing member 21c is fixed to the first bracket 21a and covers the second groove 252. The second fixing member 21c prevents the second pivot 111b from dislodging from the second groove 252. In other embodiments, the positions of the second pivot 111b of the lens assembly 11 and the second groove 252 of the first bracket 21a can be interchanged.

[0186] It is understood that the second fastener 21c can be fixed to the bottom surface of the first bracket 21a or to the second groove 252. Furthermore, the second fastener 21c can cover the entire second groove 252 or only a portion of it.

[0187] For example, the second fastener 21c can be a metal sheet, such as a steel sheet or an aluminum sheet.

[0188] For example, the second fixing member 21c supports the second rotating shaft 111b. The second fixing member 21c can also provide three-point support with each sidewall 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, thereby making the connection stability between the camera body 1 and the first carrier 21 better.

[0190] like Figure 13 As shown, the camera body 1 can be rotatably connected to the first bracket 21a via a first rotating shaft 111a and a second rotating shaft 111b. The first rotating shaft 111a and the second rotating shaft 111b can form a first rotation axis of the camera body 1. The camera body 1 can rotate relative to the first carrier 21 around the first rotation axis.

[0191] For example, since the first rotating shaft 111a and the second rotating shaft 111b are parallel to the X-axis direction, the camera body 1 can rotate relative to the first carrier 21 in the YZ plane around the X-axis direction.

[0192] Figure 15 yes Figure 8 The diagram shows a structural schematic of one embodiment of the first drive mechanism 23.

[0193] like Figure 15 As shown, the first drive 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] Understandably, the first SMA line 3a and the second SMA line 3b are made of shape memory alloys (SMA), such as nickel-titanium alloys. 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] Figure 16 yes Figure 15 A schematic diagram of one embodiment of the first reed 4a shown. Figure 17 yes Figure 16The diagram shows the structure of the first reed 4a at another angle. Figure 18 yes Figure 16 The diagram shows the structure of the first reed 4a at another angle.

[0196] like Figures 16 to 18 As shown, the first reed 4a includes a first fixed end 41a, a second fixed end 42a, and an electrical connection end 43a. 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 spring 4a and the first fixed end 41a. It is understood that in the Z-axis direction, the first fixed end 41a may be located at the top of the electrical connection end 43a or at the bottom of the electrical connection end 43a. Figures 16 to 18 This illustrates that, in the Z-axis direction, the first fixed end 41a can be located on top of the electrical connection end 43a.

[0198] For example, in the X-axis direction, there is a distance between the electrical connection end 43a and the first fixed end 41a. It can be understood that in the X-axis direction, the first fixed end 41a may be located to the left of the electrical connection end 43a or to the right of the electrical connection end 43a. Figures 16 to 18 This illustrates that, in the Z-axis direction, the first fixed end 41a can be located to the left of the electrical connection end 43a.

[0199] For example, in the Y-axis direction, there is a distance between the electrical connection end 43a and the first fixed end 41a. It is understood that in the Y-axis direction, the first fixed end 41a may be located behind the electrical connection end 43a or in front of the electrical connection end 43a. Figures 16 to 18 This illustrates that, in the Y-axis direction, the first fixed end 41a can be located behind the electrical connection end 43a.

[0200] like Figures 16 to 18 As shown, the first reed 4a includes a first segment 44a, a second segment 45a, and a third segment 46a connected in sequence. In other words, the second segment 45a of the first reed 4a is connected between the first segment 44a and the third segment 46a. The end of the first segment 44a furthest from the second segment 45a is a first fixed end 41a. The end of the third segment 46a furthest from the second segment 45a is a second fixed end 42a. At least a portion of the second segment 45a is an electrical connection end 43a.

[0201] For example, the first segment 44a of the first reed 4a includes a first sub-segment 441a and a second sub-segment 442a connected to the first sub-segment 441a. The first sub-segment 441a of the first reed 4a is connected to 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 of the first reed 4a 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 of the first reed 4a 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 of the first reed 4a 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 may 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. Further details will not be elaborated here.

[0210] Figure 19 yes Figure 3 The diagram shows a partial structural schematic of the camera module 100 in one embodiment. Figure 20 yes Figure 12 A partial cross-sectional view of one embodiment of the camera module 100 at DD.

[0211] like Figure 19 As shown, the first fixed end 41a of the first spring 4a is fixed to the camera body 1. The electrical connection end 43a and the second fixed end 42a of the first spring 4a are spaced apart from the camera body 1, i.e., not in contact. The first fixed end 41b of the second spring 4b is fixed to the camera body 1. The electrical connection ends 43b and the second fixed end 42b of the second spring 4b are spaced apart from the camera body 1. The electrical connection ends 43a and 43b of the first spring 4a are positioned opposite each other. The first fixed end 41a of the first spring 4a is located on the side of the electrical connection end 43a of the first spring 4a away from the second spring 4b. The first fixed end 41b of the second spring 4b is located on the side of the electrical connection end 43b of the second spring 4b away from the first spring 4a.

[0212] For example, the first fixing end 41a of the first spring 4a can be fixed to the first sub-side 1131 of the lens assembly 11. The second fixing end 42a and the electrical connection end 43a of the first spring 4a are both opposite to and spaced apart from the second sub-side 1132 of the lens assembly 11 of the camera body 1. The first fixing end 41b of the second spring 4b can be fixed to the third sub-side 1133 of the lens assembly 11 of the camera body 1. The second fixing end 42b and the electrical connection end 43b of the second spring 4b are both opposite to and spaced apart from the second sub-side 1132 of the lens assembly 11 of the camera body 1.

[0213] like Figure 19 As shown, the electrical connection end 43a of the first reed 4a is electrically connected to one end of the first SMA wire 3a. The electrical connection end 43b of the second reed 4b is electrically connected to the other end of the first SMA wire 3a. Thus, the first SMA wire 3a is electrically connected between the electrical connection end 43a of the first reed 4a and the electrical connection end 43b of the second reed 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 Figure 20 As shown, the second fixing end 42a of the first spring 4a is fixed to the first protrusion 255 of the first bracket 21a. The second fixing end 42b of the second spring 4b (see [reference]). Figure 19 The second protrusion 256, fixed to the first bracket 21a (see also...) Figure 11 ).

[0215] like Figure 19 and Figure 20 As shown, when the first SMA line 3a is energized, the first SMA line 3a contracts. On one hand, the first end of the first SMA line 3a applies a tensile force along the positive X-axis to the electrical connection end 43a of the first spring 4a. Figure 19 The direction of the tension 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 X-axis and a second component force along the negative Z-axis. Figure 19 (The direction of the tension is indicated by a thick arrow). On the other hand, the second end of the first SMA line 3a applies a tension force along the negative X-axis to the electrical connection end 43b of the second reed 4b. Figure 19 The direction of the tension is indicated by a thick arrow. The first fixed end 41b of the second spring 4b is subjected to a third component force along the negative X-axis and a fourth component force along the negative Z-axis. Figure 19 (The direction of the pulling force is indicated by the thick arrow). The first and third components of the force roughly cancel each other out. Under the action of the second and fourth components, the camera body 1 can pass through the first rotating shaft 111a (see [reference]). Figure 13 ) and second shaft 111b (see Figure 13 It rotates counterclockwise relative to the first carrier 21.

[0216] Figure 21 yes Figure 19 The diagram shows a partial structural view of the camera module 100 from another angle.

[0217] like Figure 21 As shown, the first fixed end 41c of the third spring 4c is fixed to the camera body 1. The electrical connection end 43c and the second fixed end 42c of the third spring 4c are both spaced apart from the camera body 1. The first fixed end 41d of the fourth spring 4d is fixed to the camera body 1. The electrical connection end 43d and the second fixed end 42d of the fourth spring 4d are both spaced apart from the camera body 1. The electrical connection end 43c of the third spring 4c and the electrical connection end 43d of the fourth spring 4d are positioned opposite each other. The first fixed end 41c of the third spring 4c is located on the side of the electrical connection end 43c of the third spring 4c away from the fourth spring 4d. The first fixed end 41d of the fourth spring 4d is located on the side of the electrical connection end 43d of the fourth spring 4d away from the third spring 4c.

[0218] For example, the first fixing end 41c of the third spring 4c can be fixed to the fourth sub-side 1141 of the lens assembly 11. The second fixing end 42c and the electrical connection end 43c of the third spring 4c are both opposite to and spaced apart from the fifth sub-side 1142 of the lens assembly 11. The first fixing end 41d of the fourth spring 4d can be fixed to the sixth sub-side 1143 of the lens assembly 11. The second fixing end 42d and the electrical connection end 43d of the fourth spring 4d are both opposite to and spaced apart from the fifth sub-side 1142 of the lens assembly 11.

[0219] like Figure 21 As shown, the electrical connection end 43c of the third reed 4c is electrically connected to one end of the second SMA line 3b. The electrical connection end 43d of the fourth reed 4d is electrically connected to the other end of the second SMA line 3b. Thus, the second SMA line 3b is electrically connected between the electrical connection end 43c of the third reed 4c and the electrical connection end 43d of the fourth reed 4d. Exemplarily, the second SMA line 3b is parallel to the extension direction of the first rotation axis P1, that is, the X-axis direction.

[0220] like Figure 20 As shown, the second fixing end 42c of the third spring 4c is fixed to the third protrusion 257 of the first bracket 21a. The second fixing end 42d of the fourth spring 4d is fixed to the fourth protrusion 258 of the first bracket 21a (see [reference]). Figure 10 ).

[0221] like Figure 20 and Figure 21 As shown, when the second SMA line 3b is energized, the second SMA line 3b contracts. On one hand, the first end of the second SMA line 3b applies a tensile force along the negative X-axis to the electrical connection end 43c of the third spring 4c. Figure 21 The direction of the tension is indicated by the thick arrow. The first fixed end 41c of the third reed 4c is subjected to a fifth component force along the negative X-axis and a sixth component force along the negative Z-axis. Figure 21 (The direction of the tension is indicated by a thick arrow). On the other hand, the second end of the second SMA line 3b applies a tension force along the positive X-axis to the electrical connection end 43d of the fourth reed 4d. Figure 21 (The direction of the tension is indicated by the thick arrow). The first fixed end 41d of the fourth reed 4d is subjected to the seventh component force along the positive X-axis and the eighth component force along the negative Z-axis. Figure 21 (The direction of the pulling force is indicated by the thick arrow). The fifth and seventh components of the force can roughly cancel each other out. Under the action of the sixth and eighth components, the camera body 1 can rotate clockwise relative to the first carrier 21 via the first rotating shaft 111a and the second rotating shaft 111b.

[0222] The following describes a specific implementation method for controlling the camera body 1 to rotate relative to the first carrier 21 via the first rotating shaft 111a and the second rotating shaft 111b, in conjunction with the relevant accompanying drawings.

[0223] like Figures 19 to 21 As shown, in one embodiment, when the first SMA wire 3a and the second SMA wire 3b are simultaneously energized to the maximum current, the first SMA wire 3a and the second SMA wire 3b contract. On one hand, the first end of the first SMA wire 3a applies a tensile force along the positive X-axis to the electrical connection end 43a of the first reed 4a. The first fixed end 41a of the first reed 4a receives a first component force along the positive X-axis and a second component force along the negative Z-axis. On the other hand, the second end of the first SMA wire 3a applies a tensile force along the negative X-axis to the electrical connection end 43b of the second reed 4b. The first fixed end 41b of the second reed 4b receives a third component force along the negative X-axis and a fourth component force along the negative Z-axis. Furthermore, the first end of the second SMA wire 3b applies a tensile force along the negative X-axis to the electrical connection end 43c of the third reed 4c. The first fixed end 41c of the third reed 4c receives a fifth component force along the negative X-axis and a sixth component force along the negative Z-axis. On the other hand, the second end of the second SMA line 3b applies a tensile force along the positive X-axis to the electrical connection end 43d of the fourth reed 4d. The first fixed end 41d of the fourth reed 4d is subjected to a seventh component force along the positive X-axis and an eighth component force along the negative Z-axis. The first and third components can approximately cancel each other out. The fifth and seventh components can also approximately cancel each other out. Furthermore, the resultant force of the second and fourth components can approximately cancel out the resultant force of the sixth and eighth components. At this point, the camera body 1 can be in a balanced state.

[0224] When the current on the first SMA line 3a is greater than the current on the second SMA line 3b (i.e., the current on the second SMA line 3b is reduced), the resultant force of the second and fourth component forces is greater than the resultant force of the sixth and eighth component forces. 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 line 3a is less than the current on the second SMA line 3b (i.e., the current on the first SMA line 3a is reduced), the resultant force of the sixth and eighth component forces is greater than the resultant force of the second and fourth component forces. At this time, the camera body 1 can rotate counterclockwise relative to the first carrier 21 via the first rotating shaft 111a and the second rotating shaft 111b.

[0226] For example, the camera body 1 rotates relative to the first carrier 21 about the first rotation axis at an angle greater than 0.8°.

[0227] Exemplarily, the angle by which the imaging body 1 rotates relative to the first carrier 21 about the first rotation axis is within the range of 1° to 4°.

[0228] The following introduces the 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. Thus, the first reed 4a can magnify the distance by which the first SMA wire 3a contracts by 3.7 times, that is, the magnification factor of the first reed 4a is 3.7. At this time, under the pulling of the first reed 4a, the imaging body 1 can rotate 3° relative to the first carrier 21 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 it can ensure the stability of the imaging body 1 during rotation, with better anti-shake accuracy, and can also ensure that the rotation angle of the imaging body 1 is not small and the anti-shake effect is good.

[0231] Exemplarily, the magnification factor of the first reed 4a is within 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 the structural setting of the first reed 4a. Details are not elaborated here.

[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 and the second section 45a of the first reed 4a satisfies: 90° < a1 < 180°, in this way, while ensuring that the rotation angle of the imaging body 1 remains unchanged, the distance by which the first fixed end 41a of the first reed 4a moves along the Z-axis direction can be reduced, 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 the structural setting of the first reed 4a. Details are not elaborated here.

[0235] The following describes one embodiment of the assembly steps of the camera body 1, the first carrier 21, and the first drive mechanism 23.

[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 upwards. 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 Figure 19 and Figure 21 As shown, the first fixed end 41a of the first spring 4a, the first fixed end 41b of the second spring 4b, the first fixed end 41c of the third spring 4c, and the first fixed end 41d of the fourth spring 4d are respectively fixed at different positions on the camera body 1, and the electrical connection end 43a of the first spring 4a is opposite to the electrical connection end 43b of the second spring 4b. The first fixed end 41a of the first spring 4a is located on the side of the electrical connection end 43a of the first spring 4a away from the second spring 4b. The first fixed end 41b of the second spring 4b is located on the side of the electrical connection end 43b of the second spring 4b away from the first spring 4a. The electrical connection end 43b of the third spring 4c is opposite to the electrical connection end 43d of the fourth spring 4d. The first fixed end 41c of the third spring 4c is located on the side of the electrical connection end 43c of the third spring 4c away from the fourth spring 4d. The first fixed end 41d of the fourth reed 4d is located on the side away from the third reed 4c of the electrical connection end 43d of the fourth reed 4d.

[0238] like Figure 19 and Figure 21 As shown, the first SMA wire 3a is electrically connected between the electrical connection end 43a of the first reed 4a and the electrical connection end 43b of the second reed 4b, and the second SMA wire 3b is electrically connected between the electrical connection end 43c of the third reed 4c and the electrical connection end 43d of the fourth reed 4d.

[0239] like Figure 12 and Figure 13 As shown, the camera body 1 is inverted, the first rotating shaft 111a of the camera body 1 is aligned with the first groove 251 and installed into the first groove 251, and the second rotating shaft 111b is aligned with the second groove 252 and installed 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 dispensing process.

[0241] The second fastener 21c is fixed to the first bracket 21a and covers the second groove 252. The first bracket 21a and the second fastener 21c support the second rotating shaft 111b. For example, the second fastener 21c can be fixed to the first bracket 21a by a dispensing process.

[0242] like Figure 20 As shown, the second fixed end 42a of the first spring 4a, the second fixed end 42b of the second spring 4b, the second fixed end 42c of the third spring 4c, and the second fixed end 42d of the fourth spring 4d are respectively fixed at different positions on the camera body 1.

[0243] Figure 22 yes Figure 8 The second carrier 22 shown is partially exploded in one embodiment. Figure 23 yes Figure 22 The diagram shows the structure of the second carrier 22 from another angle.

[0244] like Figure 22 and Figure 23 As shown, the second carrier 22 includes a second support 22a, a third fastener 22b, and a fourth fastener 22c.

[0245] For example, the second bracket 22a includes a first side 221 and a second side 222 disposed opposite to each other, and a third side 223 and a fourth side 224 disposed opposite to each other. The third side 223 and the fourth side 224 of the second bracket 22a are connected between the first side 221 and the second side 222 of the second bracket 22a.

[0246] For example, the third side 223 of the second bracket 22a includes a first sub-side 2231, a second sub-side 2232 and a third sub-side 2233 connected in sequence. The first sub-side 2231 is connected to the first side 221 of the second bracket 22a and the third sub-side 2233 is connected to the second side 222 of the second bracket 22a.

[0247] For example, the included angle between the first sub-side 2131 and the second sub-side 2132 of the second carrier 22, and the included angle between the second sub-side 2132 and the third sub-side 2133 of the second carrier 22 are both obtuse angles.

[0248] For example, the fourth side 224 of the second support 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 being connected to the second side 222 and the sixth sub-side 2243 being connected to the first side 221.

[0249] For example, the included angle between the fourth sub-side 2241 and the fifth sub-side 2242, and the included angle between the fifth sub-side 2242 and the sixth sub-side 2243 are obtuse angles.

[0250] For example, the second support 22a has an approximately octagonal shape in its cross-section parallel to the XY plane.

[0251] It is understood that the second support 22a may include fewer or more structures. For example, the shape of the cross-section of the second support 22a parallel to the XY plane may be quadrilateral, pentagonal, hexagonal, or heptagonal, etc. When the second support 22a includes more structures, it may include more sides. In this case, the shape of the cross-section of the second support 22a parallel to the XY plane may be n-sided, where n is greater than 8.

[0252] For example, the angle between two adjacent sides is 135°. In this case, the second support 22a is approximately octagonal.

[0253] like Figure 22 and Figure 23 As shown, the second bracket 22a is provided with a third groove 271 and a fourth groove 272 that are arranged opposite to each other.

[0254] For example, the third groove 271 is located at the second sub-side 2232 of the second bracket 22a. The fourth groove 272 is located at the fifth sub-side 2242 of the second bracket 22a.

[0255] It is understood that the third groove 271 and the fourth groove 272 can be connected to the first carrier 21 (see [link]). Figures 9 to 11 The first groove 251 and the second groove 252 are configured similarly or identically. Further details will not be elaborated here.

[0256] like Figure 22 and Figure 23 As shown, the second bracket 22a is also provided with a first protrusion 275 and a second protrusion 276. The first protrusion 275 and the second protrusion 276 protrude from the inner surface of the second bracket 22a.

[0257] For example, the first protrusion 275 and the second protrusion 276 protrude from the inner surface of the first side 221 of the second bracket 22a.

[0258] Understandably, although Figure 22 and Figure 23 The illustration shows that the first protrusion 275 and the second protrusion 276 are spaced apart, but the first protrusion 275 can also be connected to the second protrusion 276, in which case the first protrusion 275 and the second protrusion 276 form a protrusion.

[0259] like Figure 22 and Figure 23 As shown, the second bracket 22a is also provided with a third protrusion 277 and a fourth protrusion 278. The third protrusion 277 and the fourth protrusion 278 protrude from the inner surface of the second bracket 22a.

[0260] For example, the third protrusion 277 and the fourth protrusion 278 may protrude from the inner surface of the second side 222.

[0261] Understandably, although Figure 22 and Figure 23 The diagram shows that the third protrusion 277 and the fourth protrusion 278 are spaced apart, but the third protrusion 277 can also be connected to the fourth protrusion 278, in which case the third protrusion 277 and the fourth protrusion 278 form a protrusion.

[0262] Figure 24 yes Figure 3 The diagram shows a partial structural schematic of the camera module 100 in one embodiment.

[0263] like Figure 24 As shown, the first support 21a is located inside the second support 22a, that is, the second support 22a is arranged around the first support 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] For example, the first side 211 of the first bracket 21a is opposite to and spaced apart from the first side 221 of the second bracket 22a. The second side 212 of the first bracket 21a is opposite to and spaced apart 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 apart 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 apart 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 apart 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 apart 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 apart from the fifth sub-side 2242 of the second bracket 22a. The sixth sub-side 2143 of the first bracket 21a is opposite to and spaced apart from the sixth sub-side 2243 of the second bracket 22a.

[0265] Figure 25 yes Figure 24 The image shows a partial cross-sectional view of the camera module 100 in one embodiment on the EE line.

[0266] like Figure 25As shown, at least a portion of the third rotating shaft 259a of the first bracket 21a is located within the third groove 271 of the second bracket 22a and is rotatably connected to the groove wall of the third groove 271. A 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 dislodging from the third groove 271.

[0267] It is understood that the third fastener 22b can be fixed to the bottom surface of the second bracket 22a or fixed within the third groove 271. Furthermore, the third fastener 22b can cover the entire third groove 271 or only a portion of it.

[0268] For example, the third fastener 22b can be a metal sheet, such as a steel sheet or an aluminum sheet.

[0269] For example, the third fastener 22b supports the third rotating shaft 259a. The third fastener 22b can mate with the sidewalls of each groove of the third groove 271 to provide 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 pivot 259a of the first bracket 21a and the third groove 271 of the second bracket 22a can be interchanged.

[0271] like Figure 25 As shown, at least a portion of the fourth pivot 259b of the first bracket 21a is located within the fourth groove 272 of the second bracket 22a and is rotatably connected to the groove wall of the fourth groove 272. A fourth fixing member 22c is fixed to the second bracket 22a and covers the fourth groove 272. The fourth fixing member 22c is used to prevent the fourth pivot 259b from dislodging from the fourth groove 272. In other embodiments, the positions of the fourth pivot 259b of the first bracket 21a and the fourth groove 272 of the second bracket 22a can be interchanged.

[0272] It is understood that the fourth fastener 22c can be fixed to the bottom surface of the second bracket 22a, or it can be fixed within the fourth groove 272. Furthermore, the fourth fastener 22c can cover the entire fourth groove 272, or it can cover only a portion of the fourth groove 272.

[0273] For example, the fourth fastener 22c can be a metal sheet, such as a steel sheet or an aluminum sheet.

[0274] For example, the fourth fastener 22c supports the fourth rotating shaft 259b. The fourth fastener 22c can also provide three-point support with each sidewall 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, thereby making the connection stability between the first carrier 21 and the second carrier 22 better.

[0276] It is understood that the camera body 1 and the first carrier 21 can be rotatably connected to the second carrier 22 via the third 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] For example, since the third rotating shaft 259a and the fourth rotating shaft 259b are parallel to the Y-axis direction, the camera body 1 and the first carrier 21 can rotate relative to the second carrier 22 in the XZ plane around the Y-axis direction.

[0278] Figure 26 yes Figure 8 A schematic diagram of one embodiment of the second drive mechanism 24 is shown.

[0279] like Figure 26 As shown, the second drive mechanism 24 includes a third SMA line 5a, a fourth SMA line 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 line 5a, the fourth SMA line 5b, the fifth reed 6a, the sixth reed 6b, the seventh reed 6c, and the eighth reed 6d of the second drive mechanism 24 adopt the same or similar configuration as the first SMA line 3a, the second SMA line 3b, the first reed 4a, the second reed 4b, the third reed 4c, and the fourth reed 4d of the first drive mechanism 23. Specific details will not be elaborated here.

[0281] Figure 27 yes Figure 3 The diagram shows a partial structural schematic of the camera module 100 in one embodiment.

[0282] like Figure 27As shown, the first fixed end 61a of the fifth reed 6a is fixed to the first bracket 21a. The electrical connection end 63a and the second fixed end 62a of the fifth reed 6a are spaced apart from the first bracket 21a, i.e., not in contact. The first fixed end 61b of the sixth reed 6b is fixed to the first bracket 21a. The electrical connection ends 63b and the second fixed end 62b of the sixth reed 6b are spaced apart from the first bracket 21a. The electrical connection ends 63a and 63b of the fifth reed 6a are positioned opposite each other. The first fixed end 61a of the fifth reed 6a is located on the side of the electrical connection end 63a of the fifth reed 6a away from the sixth reed 6b. The first fixed end 61b of the sixth reed 6b is located on the side of the electrical connection end 63b of the sixth reed 6b away from the fifth reed 6a.

[0283] For example, the first fixing end 61a of the fifth spring 6a can be fixed to the sixth sub-side 2143 of the first bracket 21a. The second fixing end 62a and the electrical connection end 43a of the fifth spring 6a are both opposite to and spaced apart from the first side 211 of the first bracket 21a. The first fixing end 61b of the sixth spring 6b can be fixed to the first sub-side 2131 of the first bracket 21a. The second fixing end 62b and the electrical connection end 63b of the sixth spring 6b are both opposite to and spaced apart from the first side 211 of the first bracket 21a.

[0284] like Figure 27 As shown, the electrical connection end 63a of the fifth reed 6a is electrically connected to one end of the third SMA line 5a. The electrical connection end 63b of the sixth reed 6b is electrically connected to the other end of the third SMA line 5a. Thus, the third SMA line 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. Exemplarily, the third SMA line 5a is parallel to the extension direction of the second rotation axis P2, that is, the Y-axis direction.

[0285] Figure 28 yes Figure 27 The image shows a partial cross-sectional view of the camera module 100 along the FF line in one embodiment.

[0286] like Figure 28 As shown, the second fixing end 62a of the fifth spring 6a is fixed to the first protrusion 275 of the second bracket 22a. The second fixing end 62b of the sixth spring 6b (see [reference]) Figure 27 The second protrusion 276, fixed to the second bracket 22a (see also...) Figure 23 ).

[0287] like Figure 27 and Figure 28As shown, when the third SMA line 5a is energized, it contracts. On one hand, the first end of the third SMA line 5a applies a pulling force along the positive Y-axis to the electrical connection end 63a of the fifth reed 6a. The first fixed end 61a of the fifth reed 6a is subjected to a first component force along the positive X-axis and a second component force along the negative Z-axis. On the other hand, the second end of the third SMA line 5a applies a pulling force along the negative Y-axis to the electrical connection end 63b of the sixth reed 6b. The first fixed end 61b of the sixth reed 6b is subjected to a third component force along the negative X-axis and a fourth component force along the negative Z-axis. The first and third components roughly cancel each other out. Under the action of the second and fourth components, the camera body 1 can pass through the third rotating shaft 259a (see [reference]). Figure 25 ) and fourth shaft 259b (see Figure 25 It rotates counterclockwise relative to the second carrier 22.

[0288] Figure 29 yes Figure 27 The diagram shows a partial structural view of the camera module 100 from another angle.

[0289] like Figure 29 As shown, the first fixed end 61c of the seventh reed 6c is fixed to the first bracket 21a. The electrical connection end 63c and the second fixed end 62c of the seventh reed 6c are both spaced apart from the first bracket 21a. The first fixed end 61d of the eighth reed 6d is fixed to the first bracket 21a. The electrical connection end 63d and the second fixed end 62d of the eighth reed 6d are both spaced apart from the first bracket 21a. The electrical connection end 63c of the seventh reed 6c and the electrical connection end 63d of the eighth reed 6d are positioned opposite each other. The first fixed end 61c of the seventh reed 6c is located on the side of the electrical connection end 63c of the seventh reed 6c that is furthest from the eighth reed 6d. The first fixed end 61d of the eighth reed 6d is located on the side of the electrical connection end 63d of the eighth reed 6d that is furthest from the seventh reed 6c.

[0290] For example, the first fixed end 61c of the seventh spring 6c can be fixed to the third sub-side 2133 of the first bracket 21a. The second fixed end 62c and the electrical connection end 63c of the seventh spring 6c are both opposite to and spaced apart from the second side 212 of the first bracket 21a. The first fixed end 61d of the eighth spring 6d can be fixed to the fourth sub-side 2141 of the first bracket 21a. The second fixed end 62d and the electrical connection end 63d of the eighth spring 6d are both opposite to and spaced apart from the second side 212 of the first bracket 21a.

[0291] like Figure 29As shown, the electrical connection end 63c of the seventh reed 6c is electrically connected to one end of the fourth SMA line 5b. The electrical connection end 63d of the eighth reed 6d is electrically connected to the other end of the fourth SMA line 5b. Thus, the fourth SMA line 5b is electrically connected between the electrical connection end 63c of the seventh reed 6c and the electrical connection end 63d of the eighth reed 6d. Exemplarily, the fourth SMA line 5b is parallel to the extension direction of the second rotation axis P2, that is, the Y-axis direction.

[0292] like Figure 28 As shown, the second fixed end 62c of the seventh spring 6c is fixed to the third protrusion 277 of the second bracket 22a. The second fixed end 62d of the eighth spring 6d is fixed to the fourth protrusion 278 of the second bracket 22a.

[0293] like Figure 29 As shown, when the fourth SMA line 5b is energized, it contracts. On one hand, the first end of the fourth SMA line 5b applies a tensile force along the negative Y-axis to the electrical connection end 63c of the seventh reed 6c. The first fixed end 61c of the seventh reed 6c is subjected to a fifth component force along the negative Y-axis and a sixth component force along the negative Z-axis. On the other hand, the second end of the fourth SMA line 5b applies a tensile force along the positive Y-axis to the electrical connection end 63d of the eighth reed 6d. The first fixed end 61d of the eighth reed 6d is subjected to a seventh component force along the positive Y-axis and an eighth component force along the negative Z-axis. The fifth and seventh components roughly cancel each other out. Under the action of the sixth and eighth components, the camera body 1 can pass through the third rotating shaft 259a (see [reference]). Figure 25 ) and fourth shaft 259b (see Figure 25 It rotates clockwise relative to the second carrier 22.

[0294] The following description, in conjunction with the accompanying drawings, describes a method for controlling the camera body 1 via a third rotating shaft 259a (see attached diagram). Figure 25 ) and fourth shaft 259b (see Figure 25 ) Specific implementation of the rotation relative to the second carrier 22.

[0295] In one embodiment, the third SMA wire 5a and the fourth SMA wire 5b are simultaneously energized to their maximum current, causing them to contract. On one hand, the first end of the third SMA wire 5a applies a tensile force along the positive Y-axis to the electrical connection end 63a of the fifth reed 6a. The first fixed end 61a of the fifth reed 6a receives a first component force along the positive Y-axis and a second component force along the negative Z-axis. On the other hand, the second end of the third SMA wire 5a applies a tensile force along the negative Y-axis to the electrical connection end 63b of the sixth reed 6b. The first fixed end 61b of the sixth reed 6b receives a third component force along the negative Y-axis and a fourth component force along the negative Z-axis. Furthermore, the first end of the fourth SMA wire 5b applies a tensile force along the negative Y-axis to the electrical connection end 63c of the seventh reed 6c. The first fixed end 61c of the seventh reed 6c receives a fifth component force along the negative Y-axis and a sixth component force along the negative Z-axis. On the other hand, the second end of the fourth SMA line 5b applies a tensile force along the positive Y-axis to the electrical connection end 63d of the eighth reed 6d. The first fixed end 61d of the eighth reed 6d is subjected to a seventh component force along the positive Y-axis and an eighth component force along the negative Z-axis. The first and third components can approximately cancel each other out. The fifth and seventh components can also approximately cancel each other out. Furthermore, the resultant force of the second and fourth components can approximately cancel out the resultant force of the sixth and eighth components. At this point, the camera body 1 can be in a balanced state.

[0296] When the current on the third SMA line 5a is greater than the current on the fourth SMA line 5b (i.e., the current on the fourth SMA line 5b is reduced), the resultant force of the second and fourth component forces is greater than the resultant force of the sixth and eighth component forces. At this time, the camera body 1 can pass through the third rotating shaft 259a (see [reference]). Figure 25 ) and fourth shaft 259b (see Figure 25 It rotates clockwise relative to the second carrier 22.

[0297] When the current on the third SMA line 5a is less than the current on the fourth SMA line 5b (i.e., the current on the third SMA line 5a is reduced), the resultant force of the sixth and eighth component forces is greater than the resultant force of the second and fourth component forces. At this time, the camera body 1 can pass through the third rotating shaft 259a (see [reference]). Figure 25 ) and fourth shaft 259b (see Figure 25 It rotates counterclockwise relative to the second carrier 22.

[0298] For example, the first carrier 21 drives the camera body 1 to rotate relative to the second carrier 22 around the second rotation axis by an angle greater than 0.8°.

[0299] For example, the angle at which the first carrier 21 drives the camera body 1 to rotate relative to the second carrier 22 about the second rotation axis is in the range of 1° to 4°.

[0300] Understandably, as mentioned above, by adjusting the thickness, shape, and bending angle of each segment of the first reed 4a, a suitable magnification can be achieved. This ensures both stability and good image stabilization accuracy during the rotation of the camera body 1, while also preventing the rotation angle of the camera body 1 from being too small, thus maintaining a good image stabilization effect. Similarly, the structural settings of the fifth reed 6a, sixth reed 6b, seventh reed 6c, and eighth reed 6d are similar to those of the first reed 4a. Further details will not be elaborated here.

[0301] It is understood that the various embodiments described above all involve the gimbal module 2 driving the lens assembly 11 to rotate relative to the first carrier 21 around a first rotation axis P1, and the first carrier 21 driving the lens assembly 11 to rotate relative to the second carrier 22 around a second rotation axis P2. In other embodiments, the gimbal module 2 may also drive the image sensor assembly 12 to rotate relative to the first carrier 21 around a first rotation axis P1, and the first carrier 21 driving the image sensor assembly 12 to rotate relative to the second carrier 22 around a second rotation axis P2. The arrangement of the image sensor assembly 12 and the first carrier 21 can be found in the section on the arrangement of the lens assembly 11 and the first carrier 21. Specific details will not be elaborated here.

[0302] It is understandable that the above text specifically describes a gimbal module 2 with the relevant accompanying drawings. By setting a first carrier 21 around the camera body 1, and the camera body 1 rotating relative to the first carrier 21 around a first rotation axis P1, and a second carrier 22 around the first carrier 21, and the first carrier 21 driving the camera body 1 to rotate relative to the second carrier 22 around a second rotation axis P2, the camera body 1, the first carrier 21 and the second carrier 22 are roughly nested.

[0303] It is understandable that the first carrier 21 in this embodiment has a "multi-purpose" function. On the one hand, the first carrier 21 can cooperate with the second carrier 22 to serve as a stator for the camera body 1 to rotate around the first rotation axis P1. 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 in structural reuse, thereby simplifying the structure of the gimbal module 2 and realizing the miniaturization of the gimbal module 2.

[0304] Furthermore, the second carrier 22 in this embodiment also has a "multi-purpose" function. The second carrier 22 can cooperate with the first carrier 21 to serve as a stator for the camera body 1 to rotate around the first rotation axis P1. On the other hand, the second carrier 22 can also serve as a stator for the camera body 1 to rotate around the second rotation axis P2. Thus, the second carrier 22 can serve as a stator for 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 serves to protect the first carrier 21, the first drive mechanism 23, and the second drive mechanism 24 of the gimbal module 2. Thus, the second carrier 22 can achieve structural reuse, thereby simplifying the structure of the gimbal module 2 and enabling a miniaturized design of the gimbal module 2.

[0305] It is understandable that the second carrier 22 can serve as both a stator for the camera module 100 and a protector of the first carrier 21, the first drive mechanism 23, and the second drive mechanism 24 of the gimbal module 2. Thus, when the camera module 100 is applied to the electronic device 1000, the second carrier 22 of the gimbal module 2 can be directly fixed to the structural components (e.g., housing or mid-frame) of the electronic device 1000. Compared to traditional camera module solutions, where the gimbal module requires an outer shell to encapsulate and fix it to the structural components (e.g., housing or mid-frame) of the electronic device 100, in this embodiment, since the second carrier 22 of the gimbal module 2 can be directly fixed to the structural components (e.g., housing or mid-frame) of the electronic device 100, the camera module 100 does not need an additional outer shell, further simplifying its structure and facilitating miniaturization. In addition, the step of fixing the camera module 100 to the electronic device 1000 via a housing (such as a housing or a mid-frame) can be eliminated, reducing the cost.

[0306] In this embodiment, by setting the first rotating shaft 111a of the lens assembly 11 to cooperate with the first groove 251 of the first bracket 21a, and the second rotating shaft 111b of the lens assembly 11 to cooperate with the second groove 252 of the first bracket 21a, on the one hand, the camera body 1 can 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 body 1 in other directions can be restricted, thereby restricting the degree of freedom of the camera body 1 to rotate around the first rotation axis P1. In this way, the image stabilization of the camera body 1 is more stable and the image stabilization effect is better.

[0307] In this embodiment, by setting the third rotating shaft 259a of the first carrier 21 and the third groove 271 of the second carrier 22 to cooperate with each other, and the fourth rotating shaft 259b of the first carrier 21 and the fourth groove 272 of the second carrier 22 to cooperate with each other, on the one hand, the camera body 1 can 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 body 1 in other directions can be restricted, thereby restricting the degree of freedom of the camera body 1 to rotate around the second rotation axis P2. In this way, the image stabilization of the camera body 1 is more stable and the image stabilization effect is better.

[0308] The following describes one embodiment of the assembly steps of the first carrier 21, the second carrier 22, and the second drive mechanism 24.

[0309] like Figure 22 and Figure 23 As shown, the second carrier 22 is inverted, that is, the bottom surface of the second carrier 22 faces upwards. 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 Figure 27 and Figure 29 As shown, the first fixed end 61a of the fifth reed 6a, the first fixed end 61b of the sixth reed 6b, the first fixed end 61c of the seventh reed 6c, and the first fixed end 61d of the eighth reed 6d are fixed at different positions on the first carrier 21, and the electrical connection end 63a of the fifth reed 6a is opposite to the electrical connection end 63b of the sixth reed 6b. The first fixed end 61a of the fifth reed 6a is located on the side of the electrical connection end 63a of the fifth reed 6a away from the sixth reed 6b. The first fixed end 61b of the sixth reed 6b is located on the side of the electrical connection end 63b of the sixth reed 6b away from the fifth reed 6a. The electrical connection end 63c of the seventh reed 6c is opposite to the electrical connection end 63d of the eighth reed 6d. The first fixed end 61c of the seventh reed 6c is located on the side of the electrical connection end 63c of the seventh reed 6c away from the eighth reed 6d. The first fixed end 61d of the eighth reed 6d is located on the side away from the seventh reed 6c of the electrical connection end 63d of the eighth reed 6d.

[0311] like Figure 27 and Figure 29 As shown, the third SMA line 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 line 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 Figure 25As shown, the structure assembled with the camera body 1 and the first carrier 21 is inverted. The third rotating shaft 259a of the first carrier 21 is aligned with the third groove 271 and installed into the third groove 271. The fourth rotating shaft 259b is aligned with the fourth groove 272 and installed into the fourth groove 272.

[0313] The third fastener 22b is fixed to the second bracket 22a and covers the third groove 271. The second bracket 22a and the third fastener 22b support the third rotating shaft 259a. Exemplarily, the third fastener 22b can be fixed to the second bracket 22a by a dispensing process.

[0314] The fourth fastener 22c is fixed to the second bracket 22a and covers the fourth groove 272. The second bracket 22a and the fourth fastener 22c support the fourth rotating shaft 259b. Exemplarily, the fourth fastener 22c can be fixed to the second bracket 22a by a dispensing process.

[0315] The second fixed ends 62a of the fifth reed 6a, the sixth reed 6b, the seventh reed 6c, and the eighth reed 6d are respectively fixed at different positions on the second carrier 22.

[0316] It is understandable that after the camera module 100 is assembled, it can be installed inside 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 [link]). Figure 1 and Figure 2 This allows the camera module 100 to be connected to the structural components of the electronic device 1000.

[0317] The gimbal module 2 mentioned above 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, thereby achieving optical image stabilization of the camera module and improving the imaging quality of the camera module. The first rotation axis P1 intersects the second rotation axis P2. It can be understood that the image stabilization controlled by the gimbal module 2 can be a large-angle and low-frequency stabilization. For example, the image stabilization angle of the gimbal module 2 in this embodiment is greater than 0.8° and the frequency is less than 4Hz. The following will describe an image stabilization motor in the image sensor assembly 12 with reference to the relevant drawings. The image stabilization motor controls the movement of the image sensor 122 in the XY plane to achieve optical image stabilization of the camera module 100 and improve the imaging quality of the camera module 100. It can be understood that the image stabilization controlled by the image sensor 122 by the image stabilization motor can be a small-angle and high-frequency stabilization. For example, the image stabilization angle of the image stabilization motor is less than 0.8° and the frequency is greater than 4Hz.

[0318] In some embodiments, the image stabilization motor may include, but is not limited to, coils and magnets. When the coil is energized, it generates a Lorentz force under the influence of the magnet. This Lorentz force acts on the image sensor to drive its movement. With a constant magnetic field, the magnitude and direction of the Lorentz force can be controlled by adjusting the current in the coil, thereby controlling the displacement and direction of the image sensor on each axis.

[0319] Specifically, coils are provided on the first, second, and third sides of the image sensor. The image sensor is moved along the X-axis, Y-axis, and R-axis directions by the coils on the first, second, and third sides to achieve three-axis optical image stabilization.

[0320] In optical image stabilization motors, the number of coils on each side, the position of the coils on each side, and the size of the coils can all be set according to actual needs, and are not limited here.

[0321] In one implementation, a three-coil electromagnetic drive scheme is used.

[0322] In a three-coil electromagnetic drive scheme, the optical image stabilization motor may include a first coil, a second coil, and a third coil.

[0323] In some embodiments, a first coil is disposed on a first side of the image sensor, and a 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 the opposite side of the second coil. A third coil is disposed on a third side of the image sensor, and the third side is adjacent to both the first side and the second side.

[0324] The driver chip outputs a first current signal based on the displacement and direction of the image sensor in the X-axis direction through a current generation structure (such as a PWM drive structure). The first current signal is applied to the first coil so that the first coil generates a force on the image sensor under the action of the magnetic field, thereby applying a force along the X-axis to the image sensor and driving the image sensor to translate along the X-axis.

[0325] The driver chip outputs a second current signal based on the displacement and direction of the image sensor along the R-axis through a current generation structure (e.g., a PWM drive structure). The second current signal is applied to the second coil, so that the second coil generates a force on the image sensor under the action of a magnetic field, thereby applying a torque along the R-axis to the image sensor and driving the image sensor to rotate along the R-axis.

[0326] The driver chip outputs a third current signal based on the displacement and direction of the image sensor in the Y-axis direction through a current generation structure (such as a PWM drive structure). The third current signal is applied to the third coil, so that the third coil generates a force on the image sensor under the action of the magnetic field, thereby applying a force along the Y-axis to the image sensor and driving the image sensor to translate along the Y-axis.

[0327] In some embodiments, to further reduce crosstalk and thus reduce crosstalk compensation in drive control, the mechanical structure design can be optimized to align the mechanical center with the geometric center and the center of gravity of the image sensor, thereby achieving "multi-center unification". The mechanical center is the center of force along the X-axis and the center of force along the Y-axis generated by the third coil.

[0328] At this point, the normal passing through the center of the first coil passes through the geometric center of the image sensor, the normal passing through the center of the second coil does not pass through the geometric center of the image sensor, and the normal passing through the center of the third coil passes through the geometric center of the image sensor. Furthermore, the centroid and geometric center of the image sensor coincide. Of course, in some embodiments, if "multi-center convergence" is not considered, the normals passing through the centers of the first and second coils may not pass through the center of the image sensor. However, in this case, more crosstalk will be generated when moving the image sensor along each axis, requiring the control algorithm to perform more crosstalk compensation. More crosstalk compensation in the control algorithm will reduce the real-time performance of optical image stabilization compensation control.

[0329] For example, see Figure 30 The schematic diagram of the three-coil electromagnetic drive scheme shown indicates that after coils 92, 95 and 96 are energized, they can generate Lorentz force on the image sensor 93 under the action of magnets 98, 99a and 99b, thereby driving 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. Therefore, in Figure 30 In the diagram, the first side is the left side of the image sensor 93, the second side is the right side of the image sensor 93, and the third side is the top side of the image sensor 93. In this embodiment, the magnetization direction of the magnet can be either uniformly magnetized on all four poles of a single magnet, or two identical magnets can be bipolar magnetized and then connected together. For example... Figure 30 As shown, two magnets, one with an N pole and the other with a S pole, are connected together. When a coil is energized, a Lorentz force F is generated to the left in the magnetic field of these two magnets. Of course, the magnetization direction can also be the same as... Figure 30 The opposite is shown, but no limitation is made here.

[0331] like Figure 30 As shown, according to the Lorentz force and the left-hand rule, when coil 92 is energized, it can generate a Lorentz force F along the Y-axis under the influence of the magnetic field of magnet 99a. y When coil 95 is energized, it can generate a Lorentz force F along the Y-axis under the influence of the magnetic field of magnet 98. yr When coil 96 is energized, it generates a Lorentz force F along the X-axis under the influence of the magnetic field of magnet 99b. x .

[0332] exist Figure 30 In the image sensor, under the action of [something], it moves along the positive X-axis and under the action of [something], it moves along the negative Y-axis.

[0333] The Lorentz force generated by the coil 95 under the magnetic field after it is energized, due to its non-coincidence with the center O of the image sensor 93, has a lever arm and thus generates torque on the image sensor 93. Under the action of torque, the image sensor 93 can rotate along the R-axis in the XY plane. Figure 30 In the image sensor 93, under the influence of torque, it rotates counterclockwise in the XY plane.

[0334] in addition, Figure 30 The diagram also shows high-precision position sensors 91, 94, and 97. Position sensor 91 is placed in the middle region of coil 92, position sensor 94 is placed in the middle region of coil 95, and position sensor 97 is placed in the middle region of coil 96.

[0335] Position sensor 91, in conjunction with magnet 99a, enables position detection of the image sensor. Position sensor 94, in conjunction with magnet 98, enables position detection of the image sensor. Position sensor 97, in conjunction with magnet 99b, enables position detection 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] Understandable, Figure 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 magnets 98, 99a, and 99b are front views viewed from the negative Y-axis direction towards the positive Y-axis direction. The diagram including the N and S poles of the magnet is a side view viewed from the positive X-axis direction towards the negative X-axis direction.

[0337] It can be seen that the pitch, yaw, and roll three-axis decoupled negative feedback is achieved through position sensors 91, 94, and 97.

[0338] Based on the three-axis decoupling negative feedback of pitch, yaw and roll, the mutual decoupling of the three-axis drive control is realized.

[0339] It is understood that the electromagnetic drive scheme of this application embodiment is not limited to the three-coil electromagnetic drive scheme mentioned above, and other modified schemes can be obtained based on the above content. For example, based on Figure 30 The illustrated three-coil electromagnetic drive scheme can be modified by replacing coil 96 with three coils and coil 95 with three coils to obtain a seven-coil electromagnetic drive scheme. For example, based on... Figure 30 The three-coil electromagnetic drive scheme shown can be replaced by three coils to replace coil 96, three coils to replace coil 95, and three coils to replace coil 92, to obtain a nine-coil electromagnetic drive scheme.

[0340] In this application embodiment, different electromagnetic drive schemes can be obtained by varying the coil size, number of coils, and coil positions. The drive control logic of different electromagnetic drive schemes is similar: the drive chip applies a current of corresponding magnitude and direction to the corresponding coil based on the displacement and direction of the image sensor on each axis, thereby generating a Lorentz force acting on the image sensor to drive it to move in various directions for jitter compensation. The difference lies in the fact that electromagnetic drive schemes with more coils will have a larger electromagnetic driving force and better drive stability.

[0341] It is understood that the driving method in the embodiments of this application is not limited to the electromagnetic driving method mentioned above.
