Description

Technical Field

[0001] This application relates to the field of photography, and more particularly to a stabilization device, a camera module, and an electronic device. Background Technology

[0002] When a camera module is shaken during operation, it is prone to image blurring. Therefore, an optical image stabilization (OIS) module is often added to achieve lens image stabilization. Existing OIS modules typically use a ball bearing and a sliding groove to achieve movable contact between the lens carrier and the base. However, when the ball bearing moves within the groove, it inevitably experiences Z-axis torsion, causing the image stabilization compensation motion to deviate from the preset trajectory, which is detrimental to image quality. Utility Model Content

[0003] This application provides an image stabilization device, a camera module, and an electronic device, which helps to avoid Z-axis lens shake and improve image quality.

[0004] In a first aspect, this application provides a shake-stabilizing device, including a carrier, a base, a movable component, and a drive component, wherein the carrier and the base are arranged sequentially along a first direction. The movable component includes a first support rod, a second support rod, a first movable member, a second movable member, and a third movable member. The first and second support rods are located between the carrier and the base, connected and forming an angle, with the first support rod extending along a second direction and the second support rod extending along a third direction. The second direction is perpendicular to the first direction, the third direction is perpendicular to the first direction, and the second and third directions intersect. The first movable member is fixedly or movably connected to the end of the first support rod away from the second support rod; the second movable member is fixedly or movably connected to the connection point of the first and second support rods; and the third movable member is fixedly or movably connected to the end of the second support rod away from the first support rod. All movable members are in movable contact with the carrier and all movable members are in movable contact with the base. The drive component is connected to the carrier and is used to drive the carrier to move relative to the base in a plane perpendicular to the first direction.

[0005] In this embodiment, the first support rod and the second support rod are connected and form an angle, together constituting an "L-shaped" support frame, which can be referred to as an L-shaped support frame. By fixing or movably connecting at least three movable parts at intervals to the L-shaped support frame, all movable parts can be fixed within the plane (e.g., the XY plane) where the support frame is located. All movable parts slide within this plane, accompanied by slight rolling, suppressing third-direction (Z-direction) torsion of the movable parts. This prevents the image stabilization compensation movement of the carrier and its fixed lens assembly from deviating from the preset trajectory, thus improving image quality. Furthermore, since these movable parts are located in the same plane, it is beneficial for reducing the thickness of the image stabilization device, thereby facilitating the miniaturization of the camera module and electronic equipment.

[0006] In one implementation of the first aspect, the first support rod is provided with a first through hole, the first support rod or the second support rod is provided with a second through hole, the second support rod is provided with a third through hole, the first movable member is fixedly or movably connected to the first through hole, the second movable member is fixedly or movably connected to the second through hole, and the third movable member is fixedly or movably connected to the third through hole.

[0007] In this implementation, the moving parts are either fixedly or movably connected to the through holes of the first or second support rod, resulting in a simple structure and high reliability.

[0008] In one implementation of the first aspect, the first movable member is welded to the end of the first support rod away from the second support rod, the second movable member is welded to the connection between the first support rod and the second support rod, and the third movable member is welded to the end of the second support rod away from the first support rod.

[0009] In this implementation, the moving parts are directly welded to the support rod, which eliminates the need for through holes in the support rod, resulting in a simpler structure and easier manufacturing.

[0010] In one implementation of the first aspect, the carrier is able to move in a third direction relative to the first movable member, the second movable member, and the third movable member, and the base is able to move in a second direction relative to the first movable member, the second movable member, and the third movable member.

[0011] In this implementation, by making all moving parts contact the carrier in the third direction and all moving parts contact the base in the second direction, the movement of the carrier in the second direction and the movement in the third direction can be independent of each other, avoiding crosstalk between the two, improving the accuracy of the carrier's anti-shake compensation motion, and thus improving the imaging quality.

[0012] In one implementation of the first aspect, the carrier is provided with a first slide groove, a second slide groove, and a third slide groove, the openings of which face the base. The first and second slide grooves are arranged sequentially along a second direction, and the second and third slide grooves are arranged sequentially along a third direction. The dimension of the first slide groove along the third direction is greater than its dimension along the second direction, the dimension of the second slide groove along the third direction is greater than its dimension along the second direction, and the dimension of the third slide groove along the third direction is greater than its dimension along the second direction. The base is provided with a fourth slide groove, a fifth slide groove, and a sixth slide groove, the openings of which face the carrier, and the positions of the fourth, fifth, and sixth slide grooves correspond to the positions of the first, second, and third slide grooves, respectively. The fourth and fifth slide grooves are arranged sequentially along the second direction, and the fifth and sixth slide grooves are arranged sequentially along the third direction. The dimension of the fourth slide along the second direction is greater than the dimension of the fourth slide along the third direction; the dimension of the fifth slide along the second direction is greater than the dimension of the fifth slide along the third direction; the dimension of the sixth slide along the second direction is greater than the dimension of the sixth slide along the third direction. The first movable member is received within the first slide and the fourth slide; the second movable member is received within the second slide and the fifth slide; the third movable member is received within the third slide and the fifth slide.

[0013] In this implementation, the movable parts make contact with the carrier and base through sliding grooves. This simple structure helps reduce friction and thus the required thrust. Furthermore, by ensuring that the length directions of the first, second, and third sliding grooves on the carrier are all along a third direction, and the length directions of the fourth, fifth, and sixth sliding grooves on the base are all along a second direction, the orthographic projections of the first and fourth sliding grooves along the first direction intersect (e.g., orthogonally), the second and fifth sliding grooves along the first direction intersect (e.g., orthogonally), and the third and sixth sliding grooves along the first direction intersect (e.g., orthogonally). This groove arrangement resembles multiple "crosses" and can be called a cross-shaped groove. This cross-shaped groove arrangement allows all movable parts to make contact with the carrier in the third direction and with the base in the second direction, thus ensuring that the movement of the carrier along the second and third directions is independent and avoids crosstalk between them.

[0014] In one implementation of the first aspect, the dimension of the bottom of the second chute along the second direction is smaller than the dimension of the opening of the second chute along the second direction. The second chute includes a first bottom surface and a first side surface and a second side surface opposite to each other along the second direction, both of which are inclined relative to the first bottom surface. The dimension of the bottom of the third chute along the second direction is smaller than the dimension of the opening of the third chute along the second direction. The third chute includes a second bottom surface and a third side surface and a fourth side surface opposite to each other along the second direction, both of which are inclined relative to the second bottom surface. And / or, the dimension of the bottom of the fourth chute along the third direction is smaller than the dimension of the opening of the fourth chute along the third direction. The fourth chute includes a third bottom surface and a fifth side surface and a sixth side surface opposite to each other along the third direction, both of which are inclined relative to the third bottom surface. The dimension of the bottom of the fifth chute along the third direction is smaller than the dimension of the opening of the fifth chute along the third direction. The fifth chute includes a fourth bottom surface and a seventh side surface and an eighth side surface opposite to each other along the third direction, both of which are inclined relative to the fourth bottom surface.

[0015] In this implementation, the "surface inclined relative to the bottom surface" in the second or third slide groove can be, for example, a straight inclined surface or an arc-shaped surface, and the second and third slide grooves can be V-shaped slide grooves or arc-shaped slide grooves. By making the second and third slide grooves V-shaped slide grooves or arc-shaped slide grooves, the second moving member can achieve bidirectional line contact with the two side walls of the second slide groove, and the third moving member can achieve bidirectional line contact with the two side walls of the third slide groove, which is beneficial to reduce frictional resistance while achieving guidance.

[0016] In this implementation, the "surface inclined relative to the bottom surface" in the fourth and fifth slides can be, for example, a straight inclined surface or an arc-shaped surface, and the fourth and fifth slides can be V-shaped slides or arc-shaped slides. By making the fourth and fifth slides V-shaped slides or arc-shaped slides, the first moving member can achieve bidirectional line contact with the two side walls of the fourth slide, and the second moving member can achieve bidirectional line contact with the two side walls of the fifth slide, which helps to reduce frictional resistance while achieving guidance.

[0017] In one implementation of the first aspect, the first movable member contacts the bottom surface of the first slide groove and the bottom surface of the fourth slide groove, the second movable member contacts the bottom surface of the second slide groove and the fifth slide groove, and the third movable member contacts the bottom surface of the third slide groove and the sixth slide groove.

[0018] In this implementation, by ensuring that each moving part can fully contact the bottom surface of its corresponding groove, the reliability of the movement of the moving part can be guaranteed.

[0019] In one implementation of the first aspect, the driving component includes a first magnet, a second magnet, a first coil, and a second coil. The first magnet and the second magnet are fixed to a carrier, and the first coil and the second coil are fixed to a base. The first magnet and the first coil are arranged opposite to each other, and the second magnet and the second coil are arranged opposite to each other. The first coil is used to drive the carrier to move along a second direction together with the first magnet, and the second coil is used to drive the carrier to move along a third direction together with the second magnet.

[0020] In this implementation, the first coil is energized and interacts with the first magnet, thereby driving the first magnet and the carrier to move along the second direction. The second coil is energized and interacts with the second magnet, thereby driving the second magnet and the carrier to move along the third direction. This helps to further reduce the crosstalk risk of the carrier moving along the second direction and moving along the third direction.

[0021] In one implementation of the first aspect, a magnetic absorbing sheet is fixed to the side of the base facing the carrier, and the magnetic absorbing sheet is used to magnetically attract the support frame; and / or, the anti-shake device includes a plurality of elastic elements, one end of each elastic element is fixedly connected to the carrier, and the other end of each elastic element is fixedly connected to the base.

[0022] In this implementation, the support frame is fixed between the base and the carrier in the first direction by magnetic clasps and / or elastic elements, which can further prevent the fixed movable parts on the support frame from shaking in the first direction, thereby preventing the carrier and its fixed lens assembly from shaking in the first direction.

[0023] Secondly, embodiments of this application provide a camera module, which includes a lens assembly, a photosensitive element, and any one of the aforementioned image stabilization devices, with the lens assembly fixed to a carrier.

[0024] In this embodiment, the image stabilization device of the camera module prevents the image stabilization compensation movement of the carrier and its fixed lens assembly from deviating from the preset trajectory, which is beneficial to improving the imaging quality of the camera module.

[0025] Thirdly, embodiments of this application provide an electronic device, including a main body and any of the above-mentioned camera modules, wherein the camera module is disposed on the main body.

[0026] In this embodiment, the use of the aforementioned camera module in the electronic device is beneficial for improving the shooting effect. Attached Figure Description

[0055] Figure 1 This is a schematic diagram of the structure of an electronic device 1 in one embodiment. For example... Figure 2 and Figure 3 As shown, for ease of description, the X-axis can be defined as the width direction of electronic device 1, the Y-axis as the length direction of electronic device 1, and the Z-axis as the height direction of electronic device 1. It is understood that the coordinate system of electronic device 1 can be flexibly set according to specific practical needs and is not limited to the one described above.

[0056] like Figure 1 As shown, electronic device 1 can be, for example, a mobile phone. Electronic device 1 may include a camera cell module (CCM) 10, a housing 20, and a display screen (not shown). It is understood that the accompanying drawings in this embodiment only schematically show some components of electronic device 1, and the actual structure, size, position, and number of these components are not limited by the figures shown. In this embodiment, the part of electronic device 1 other than the camera module 10 can be referred to as the main body. It is readily understood that the main body includes the housing 20 and the display screen, etc., and the camera module 10 is installed in the main body.

[0057] like Figure 1 As shown, for example, the housing 20 may include a first housing 201 and a second housing 202. The first housing 201 may be, for example, a rear housing (hereinafter referred to as rear housing 201), and the second housing 202 may be, for example, a mid-frame (hereinafter referred to as mid-frame 202). The rear housing 201 and the display screen may be respectively connected to the two sides of the mid-frame 202. The rear housing 201 and the mid-frame 202 may enclose the internal space of the electronic device 1. Various devices, such as batteries, receivers, microphones, etc., may be arranged inside the electronic device 1.

[0058] Figure 1 The image shows one camera module 10 of the electronic device 1. This is merely an illustrative example and is not intended to limit the number of camera modules 10. The electronic device 1 may also have multiple camera modules 10 as needed.

[0060] In this embodiment, the optical axis direction of the camera module 10 can be the thickness direction of the electronic device 1.

[0061] Figure 2 for Figure 1 A three-dimensional structural diagram of the camera module 10. (See diagram below.)

In this embodiment, the first direction described below can be defined as the Z-axis direction, the second direction as the X-axis direction, and the third direction as the Y-axis direction. The first direction, the second direction, and the third direction can be perpendicular or approximately perpendicular to each other. It is understood that the perpendicularity of the first direction, the second direction, and the third direction is only an illustrative example. For example, the first direction can be the height direction of the carrier 121 and the base 122, or it can be the optical axis direction of the camera module 10. In another embodiment, the second direction and the third direction are both perpendicular to the first direction, and the second direction and the third direction can intersect but are not perpendicular.

The carrier 121 and the base 122 may be arranged sequentially along a first direction, with the movable component 125 located between the carrier 121 and the base 122. The multiple elastic elements 124 may be, for example, spring sheets. These elastic elements 124 can be used to elastically connect the carrier 121 and the base 122, allowing the movable component 125 to be fixed between the carrier 121 and the base 122 along the first direction. They can also be used to reset the carrier 121 after image stabilization compensation movement, as will be explained below. In another embodiment, whether or not to provide elastic elements 124 can be determined according to product requirements.

[0065] Figure 5 This is a three-dimensional structural diagram of active component 125. Figure 6 for Figure 5 A three-dimensional structural diagram of the support frame 125a.

[0066] like Figure 5 As shown, the movable component 125 may include a support frame 125a and at least three movable parts that are fixedly connected to the support frame 125a.

The shape of the support frame 125a is similar to an "L-shape", and this support frame 125a may be called an L-shaped support frame 125a.

[0068] like Figure 5 As shown, there may be three movable parts, including a first movable part 125b, a second movable part 125c, and a third movable part 125d. The first movable part 125b is fixedly or movably connected to the end of the first support rod 1251a away from the second support rod 1252a. The second movable part 125c is fixedly or movably connected to the connection between the first support rod 1251a and the second support rod 1252a. The third movable part 125d is fixedly or movably connected to the end of the second support rod 1252a away from the first support rod 1251a. That is, the second movable part 125c can be fixedly or movably connected to one end of the support frame 125a, and the third movable part 125d can be fixed to the other end of the support frame 125a. For example, these movable parts can be spheres, ellipsoids, or other shapes that meet the requirements.

[0069] Combination Figure 5 and Figure 6As shown, in one possible embodiment, the support frame 125a may be provided with a first through hole 1255a, a second through hole 1254a, and a third through hole 1253a. Specifically, the first support rod 1251a may be provided with the first through hole 1255a, either the first support rod 1251a or the second support rod 1252a may be provided with the second through hole 1254a, and the second support rod 1252a may be provided with the third through hole 1253a. A first movable member 125b is fixedly or movably connected within the first through hole 1255a, a second movable member 125c is fixedly or movably connected within the second through hole 1254a, and a third movable member 125d is fixedly or movably connected within the third through hole 1253a. These movable members are all fixedly or movably connected within the through holes of the support frame 125a, resulting in a simple structure and high reliability.

[0070] Combination Figure 5 and Figure 6 As shown, in the above embodiment, the first movable member 125b can be engaged with the support frame 125a through the first through hole 1255a, the second movable member 125c can be engaged with the support frame 125a through the second through hole 1254a, and the third movable member 125d can be engaged with the support frame through the third through hole 1253a. In this embodiment, by having the movable members engaged in the through holes of the support frame 125a, the disassembly and replacement of the movable members can be facilitated.

[0071] Combination Figure 5 and Figure 6 As shown, in the above embodiment, the first movable member 125b, the second movable member 125c, and the third movable member 125d can also be welded to the support frame 125a. In this embodiment, the first movable member 125b, the second movable member 125c, and the third movable member 125d are all welded to the support frame 125a, which can enhance the reliability and stability of the connection between the movable members and the support frame 125a.

[0072] refer to Figure 5 As shown, in another embodiment, the first support rod 1251a and the second support rod 1252a may not have through holes. The first movable member 125b can be directly welded to the end of the first support rod 1251a away from the second support rod 1252a. The second movable member 125c can be directly welded to the connection between the first support rod 1251a and the second support rod 1252a. The third movable member 125d can be directly welded to the end of the second support rod 1252a away from the first support rod 1251a. In this embodiment, the structure of the first support rod 1251a and the second support rod 1252a is simple and easy to manufacture.

[0073] like Figure 4 and Figure 5As shown, these movable parts can all make movable contact with the carrier 121 and the base 122.

The first part 1251b, the third part 1251c and the fifth part 1251d can be used to make contact with the carrier 121, and the second part 1252b, the fourth part 1252c and the sixth part 1252d can be used to make contact with the base 122, which will be further explained below.

[0074] It is understood that the active contact in the embodiments of this application refers to sliding contact, which may be accompanied by a small range of rolling contact; the movement in the embodiments of this application refers to sliding, which may be accompanied by slight rolling.

[0075] It is understandable that Part 1251b, Part 3251c and Part 5251d can also be referred to as the upper part of each moving part, and Part 2252b, Part 4252c and Part 6252d can also be referred to as the lower part of each moving part.

[0076] Understandable, Figure 4 and Figure 5 The movable component 125 shown and described above only includes the first movable member 125b, the second movable member 125c, and the third movable member 125d; this is merely an illustrative example. In another embodiment, the movable component 125 may have more than three movable members, for example, it may also include a fourth movable member and a fifth movable member. The fourth and fifth movable members are both fixedly or movably connected to the support frame 125a. The fourth movable member may be located between the first movable member 125b and the second movable member 125c, and the fifth movable member may be located between the second movable member 125c and the third movable member 125d.

[0077] Figure 7 This is a schematic diagram of the three-dimensional structure of carrier 121. Figure 8 for Figure 7 A three-dimensional structural diagram of the carrier 121 from another perspective.

[0078] Combination Figure 2 and Figure 7As shown, for example, the carrier 121 may be provided with a through hole 121a, which can be used to support the lens assembly 11. In another embodiment, whether the carrier 121 is provided with a through hole 121a can be determined according to product requirements.

[0079] like Figure 7 As shown, exemplarily, the outer wall of the carrier 121 may be provided with a plurality of protrusions 121b, for example, four protrusions 121b may be provided, wherein two protrusions 121b may be positioned opposite to the other two protrusions 121b in a third direction (Y direction). Each protrusion 121b may be used to fixally connect to one end of an elastic member 124, as will be described below. In another embodiment, the carrier 121 may also be without protrusions 121b.

[0080] Combination Figure 4 , Figure 7 and Figure 8 As shown, exemplarily, the carrier 121 may have a first groove 121c and a second groove 121d, the openings of which can both face the base 122. The first groove 121c and the second groove 121d can be used to place the first magnet 123a and the second magnet 123c of the drive assembly 123, as will be described below. In another embodiment, the carrier 121 may not have the first groove 121c and the second groove 121d, and the magnets can be directly fixed to the surface of the carrier 121.

[0081] Combination Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the carrier 121 may be provided with a first slide groove 121e, a second slide groove 121f, and a third slide groove 121g, the openings of which may all face the base 122. The first slide groove 121e and the second slide groove 121f may be arranged sequentially along a second direction (X direction), and the second slide groove 121f and the third slide groove 121g may be arranged sequentially along a third direction (Y direction). The first slide groove 121e, the second slide groove 121f, and the third slide groove 121g may be used to make active contact with the first part 1251b, the third part 1251c, and the fifth part 1251d, respectively, as will be explained below.

[0082] Combination Figure 5 , Figure 7 and Figure 8As shown, by creating the first groove 121e, the second groove 121f, and the third groove 121g on the carrier 121, active contact between the movable component and the carrier 121 can be achieved. This helps to reduce the frictional force experienced by the carrier 121 during its movement relative to the base 122, thereby reducing the thrust required for the carrier 121 to move. In another embodiment, the active contact structure between the carrier 121 and the movable component is not limited to those described above.

[0083] Figures 9(A), 9(B), and 9(C) are respectively Figure 8 The enlarged structural diagrams of parts A, B and C of the carrier 121 are also enlarged structural diagrams of the first groove 121e, the second groove 121f and the third groove 121g.

[0084] Referring to Figures 9(A), 9(B), and 9(C), the dimension of the first slide groove 121e along the third direction can be greater than the dimension of the first slide groove 121e along the second direction, the dimension of the second slide groove 121f along the third direction can be greater than the dimension of the second slide groove 121g along the third direction can be greater than the dimension of the third slide groove 121g along the second direction. The depth direction of the first slide groove 121e, the length direction of the second slide groove 121f, and the width direction of the third slide groove 121g can all be along the first direction (Z direction), the length direction of the third slide groove 121f can all be along the third direction (Y direction), and the width direction of the third slide groove 121g can all be along the second direction (X direction).

[0085] It is understood that the groove bottom width mentioned in the embodiments of this application refers to the width of the bottom of the groove, and the groove opening width refers to the width of the opening of the groove. For example, the bottom widths of the first slide groove 121e, the second slide groove 121f, and the third slide groove 121g refer to the dimensions of the bottoms of the first slide groove 121e, the second slide groove 121f, and the third slide groove 121g along the second direction; the opening widths of the first slide groove 121e, the second slide groove 121f, and the third slide groove 121g refer to the dimensions of the openings of the first slide groove 121e, the second slide groove 121f, and the third slide groove 121g along the second direction; the bottom widths of the fourth slide groove 122d, the fifth slide groove 122e, and the sixth slide groove 122f refer to the dimensions of the bottoms of the fourth slide groove 122d, the fifth slide groove 122e, and the sixth slide groove 122f along the third direction; and the opening widths of the fourth slide groove 122d, the fifth slide groove 122e, and the sixth slide groove 122f refer to the dimensions of the openings of the fourth slide groove 122d, the fifth slide groove 122e, and the sixth slide groove 122f along the third direction.

[0086] As shown in Figure 9(A), for example, the first groove 121e can be a rectangular groove, and the bottom width D1 of the first groove 121e can be equal to the opening width D2 of the first groove 121e. In another embodiment, the bottom width D1 of the first groove 121e can be smaller than the opening width D2 of the first groove 121e. The first groove 121e can include a bottom surface and two opposite sides along the second direction. Both sides can be inclined relative to the bottom surface, for example, they can be straight or curved surfaces. A second groove 121f where the bottom width D1 is smaller than the opening width D2 and both opposite sides along the second direction are straight surfaces can be called a V-shaped groove; a second groove 121f where the bottom width D1 is smaller than the opening width D2 and both opposite sides along the second direction are curved surfaces can be called an arc-shaped groove.

[0087] As shown in Figure 9(B), by way of example, the bottom width D3 of the second groove 121f can be smaller than the opening width D4 of the second groove 121f. The second groove 121f may include a first bottom surface 1212f and a first side surface 1211f and a second side surface 1213f opposite to each other along a second direction. The first side surface 1211f and the second side surface 1213f can both be inclined relative to the first bottom surface 1212f, for example, they can be inclined straight surfaces or curved surfaces. Among them, the second groove 121f with a bottom width D3 smaller than the opening width D4 and both the first side surface 1211f and the second side surface 1213f being inclined straight surfaces can be called a V-shaped groove; the second groove 121f with a bottom width D3 smaller than the opening width D4 and both the first side surface 1211f and the second side surface 1213f being curved surfaces can be called a curved groove.

[0088] As shown in Figure 9(C), by way of example, the bottom width D5 of the third groove 121g can be smaller than the opening width D6 of the third groove 121g. The third groove 121g may include a second bottom surface 1212g and a third side surface 1211g and a fourth side surface 1213g opposite to each other along the second direction. The third side surface 1211g and the fourth side surface 1213g can both be inclined surfaces relative to the second bottom surface 1212g, for example, they can be inclined straight surfaces or curved surfaces. Among them, the third groove 121g with a bottom width D5 smaller than the opening width D6 and both the third side surface 1211g and the fourth side surface 1213g being inclined straight surfaces can be called a V-shaped groove; the third groove 121g with a bottom width D5 smaller than the opening width D6 and both the third side surface 1211g and the fourth side surface 1213g being curved surfaces can be called a curved groove.

[0089] Combination Figure 5As shown in Figures 9(A), 9(B), and 9(C), by setting the second slide groove 121f as a V-shaped slide groove or an arc-shaped slide groove with its length direction along a third direction, the third part 1251c of the second movable member 125c can move only within the second slide groove 121f along a third direction; by setting the third slide groove 121g as a V-shaped slide groove or an arc-shaped slide groove with its length direction along a third direction, the fifth part 1251d of the third movable member 125d can slide only within the third slide groove 121g along a third direction, as will be explained below. With the above settings, the movable component 125 can make active contact with the carrier 121 along a third direction, as will be further explained below.

[0090] It is understood that the second slide groove 121f and the third slide groove 121g are V-shaped or arc-shaped slide grooves, which allows the second movable member 125c to achieve bidirectional line contact with the two side walls of the second slide groove 121f, and the third movable member 125d to achieve bidirectional line contact with the two side walls of the third slide groove 121g, which is beneficial to reduce frictional resistance while achieving guidance. In another embodiment, the first slide groove 121e, the second slide groove 121f, and the third slide groove 121g can all be rectangular slide grooves with their length direction along a third direction. The first slide groove 121e abuts against the first movable member 125b along the second direction, so that the first movable member 125b moves only along the third direction within the first slide groove 121e; the second slide groove 121f abuts against the second movable member 125c along the second direction, so that the second movable member 125c moves only along the third direction within the second slide groove 121f; the third slide groove 121g abuts against the third movable member 125d along the second direction, so that the third movable member 125d moves only along the third direction within the third slide groove 121g.

[0091] Figure 10 This is a schematic diagram of the three-dimensional structure of base 122. Figure 10 As shown, the outer wall of the base 122 may be provided with a plurality of protrusions 122a, the number of protrusions 122a may be the same as the number of protrusions 121b, and the positions of protrusions 122a and protrusions 121b may correspond to those of protrusions 121b in the first direction. Each protrusion 122a may be used to fixally connect to the other end of an elastic member 124.

[0092] Combination Figure 3 , Figure 4 and Figure 10As shown, the number of elastic elements 124 can be the same as the number of protrusions 121b or 122a. One end of each elastic element 124 is fixedly connected to a protrusion 121b, and the other end is fixedly connected to a protrusion 122a, allowing the carrier 121 and the base 122 to be elastically connected. The carrier 121 is fixed relative to the base 122 in a first direction, but movable in a second direction, thus allowing the movable component 125 to be fixed between the carrier 121 and the base 122 in the first direction. This ensures that the support frame 125a and the movable component are fixed between the carrier 121 and the base 122 in the first direction. Furthermore, the elastic element 124 ensures that after the anti-shake compensation movement ends, the carrier 121 returns to its initial position due to the elastic force of the elastic element 124, thus achieving the reset of the carrier 121. In another embodiment, the carrier 121 and the base 122 may not have protrusions, and both ends of the elastic element 124 can be directly fixedly connected to the outer walls of the carrier 121 and the base 122.

[0093] Combination Figure 4 and Figure 10 As shown, a magnetic locating piece (not shown) can be fixed to the side of the base 122 facing the carrier 121. The magnetic locating piece can be used to magnetically attract the support frame 125a, thereby fixing the support frame 125a between the carrier 121 and the base 122 along the first direction, thus fixing the support frame 125a and the movable part to the carrier 121 and the base bracket along the first direction. In another embodiment, the base 122 may not have a magnetic locating piece.

[0094] Combination Figure 2 , Figure 4 and Figure 10 As shown, the base 122 may have a through hole 122b, which can communicate with the through hole 121a. The camera module 10 may also include a photosensitive element (not shown), which can be disposed on the image side of the lens assembly 11, for example, it can be disposed in the through hole 122b or on the side of the base 122 away from the carrier 121. The photosensitive element can receive light transmitted through the through hole 122b. In another embodiment, whether the base 122 has a through hole 122b can be determined according to product requirements.

[0095] Combination Figure 4 and Figure 10 As shown, the base 122 may have a fourth groove 122g and a third groove 122c, the openings of which may face the carrier 121. The fourth groove 122g and the third groove 122c may be used to place the first coil 123b and the second coil 123d of the drive assembly 123, as will be described below. In another embodiment, the base 122 may not have the fourth groove 122g and the third groove 122c, and the coil may be directly fixed to the surface of the base 122.

[0096] Combination Figure 4 and Figure 10 As shown, the bottom wall of the fourth groove 122g can be provided with a receiving groove 1221g, and the bottom wall of the third groove 122c can be provided with a receiving groove 1221c. The openings of both the receiving grooves 1221g and 1221c can face the carrier 121. The receiving grooves 1221g and 1221c can be used to house the first position sensor 123e and the second position sensor 123f of the drive assembly 123, as will be described below. In another embodiment, the positions of the receiving grooves 1221g and 1221c are not limited to those described above, or the base 122 may not have the receiving grooves 1221g and 1221c, and the position sensors can be directly fixed to the surface of the base 122.

[0097] Combination Figure 4 , Figure 5 and Figure 10 As shown, the base 122 may be provided with a fourth slide groove 122d, a fifth slide groove 122e, and a sixth slide groove 122f. The openings of the fourth slide groove 122d, the fifth slide groove 122e, and the sixth slide groove 122f may all face the carrier 121, and the positions of the fourth slide groove 122d, the fifth slide groove 122e, and the sixth slide groove 122f may correspond to the positions of the first slide groove 121e, the second slide groove 121f, and the third slide groove 121g, respectively. The fourth slide groove 122d and the fifth slide groove 122e may be arranged sequentially along the second direction (X direction), and the fifth slide groove 122e and the sixth slide groove 122f may be arranged sequentially along the third direction (Y direction). The fourth slide groove 122d, the fifth slide groove 122e, and the sixth slide groove 122g may be used to make active contact with the second part 1252b, the fourth part 1252c, and the sixth part 1252d, respectively, as will be explained below.

[0098] Combination Figure 5 and Figure 10 As shown, by providing a fourth sliding groove 122d, a fifth sliding groove 122e, and a sixth sliding groove 122f on the base 122, the movable part can achieve active contact with the base 122, which helps to reduce the frictional force experienced by the carrier 121 during its movement relative to the base 122, thereby reducing the thrust required for the carrier 121 to move. In another embodiment, the active contact structure between the base 122 and the movable part is not limited to those described above.

[0099] Figures 11(A), 11(B), and 11(C) are respectively Figure 10 The enlarged structural diagrams of the base 122 at points D, E, and F are also enlarged structural diagrams of the fourth slide groove 122d, the fifth slide groove 122e, and the sixth slide groove 122f.

[0100] Referring to Figures 11(A), 11(B), and 11(C), the dimension of the fourth slide groove 122d along the second direction can be greater than its dimension along the third direction; the dimension of the fifth slide groove 122e along the second direction can be greater than its dimension along the third direction; and the dimension of the sixth slide groove 122f along the second direction can be greater than its dimension along the third direction. The depth direction of the fourth slide groove 122d, the length direction of the fifth slide groove 122e, and the width direction of the sixth slide groove 122f can all be along the first direction (Z-direction), the length direction of the sixth slide groove 122e can all be along the second direction (X-direction), and the width direction of the sixth slide groove 122f can all be along the third direction (Y-direction).

[0101] As shown in Figure 11(A), by way of example, the bottom width D7 of the fourth groove 122d can be smaller than the opening width D8 of the fourth groove 122d. The fourth groove 122d may include a third bottom surface 1222d and a fifth side surface 1221d and a sixth side surface 1223d opposite to each other along a third direction. The fifth side surface 1221d and the sixth side surface 1223d can both be inclined surfaces relative to the third bottom surface 1222d, for example, they can be inclined straight surfaces or curved surfaces. Among them, the fourth groove 122d with a bottom width D7 smaller than the opening width D8 and both the fifth side surface 1221d and the sixth side surface 1223d being inclined straight surfaces can be called a V-shaped groove; the fourth groove 122d with a bottom width D7 smaller than the opening width D8 and both the fifth side surface 1221d and the sixth side surface 1223d being curved surfaces can be called a curved groove.

[0102] As shown in Figure 11(B), by way of example, the bottom width D9 of the fifth groove 122e can be smaller than the opening width D10 of the fifth groove 122e. The fifth groove 122e may include a fourth bottom surface 1222e and a seventh side surface 1221e and an eighth side surface 1223e opposite to each other along a third direction. The seventh side surface 1221e and the eighth side surface 1223e can both be inclined surfaces relative to the fourth bottom surface 1222e, for example, they can be inclined straight surfaces or curved surfaces. Among them, the fifth groove 122e in which the bottom width D9 is smaller than the opening width D10 and the seventh side surface 1221e and the eighth side surface 1223e are both inclined straight surfaces can be called a V-shaped groove; the fifth groove 122e in which the bottom width D9 is smaller than the opening width D10 and the seventh side surface 1221e and the eighth side surface 1223e are both curved surfaces can be called a curved groove.

[0103] As shown in Figure 11(C), for example, the sixth groove 122f can be a rectangular groove, and the bottom width D11 of the sixth groove 122f can be equal to the opening width D12 of the sixth groove 122f. In another embodiment, the bottom width D11 of the sixth groove 122f can be smaller than the opening width D12 of the sixth groove 122f. The sixth groove 122f can include a bottom surface and two opposite sides along a third direction. Both sides can be inclined surfaces relative to the bottom surface, such as straight surfaces or curved surfaces. Among them, the fourth groove 122d with a bottom width D11 smaller than the opening width D12 and two opposite sides along a third direction being straight surfaces can be called a V-shaped groove; the fourth groove 122d with a bottom width D11 smaller than the opening width D12 and two opposite sides along a third direction being curved surfaces can be called an arc-shaped groove.

[0104] Combination Figure 5 , Figure 8 As shown in Figures 11(A)-(C), by setting the fourth slide groove 122d as a V-shaped slide groove or an arc-shaped slide groove with its length direction along the second direction, the second part 1252b of the first movable member 125b can move only along the second direction within the fourth slide groove 122d; by setting the fifth slide groove 122e as a V-shaped slide groove or an arc-shaped slide groove with its length direction along the second direction, the fourth part 1252c of the second movable member 125c can move only along the second direction within the fifth slide groove 122e, as will be explained below. With the above settings, the movable component 125 can make contact with the base 122 along the second direction, as will be further explained below.

[0105] It is understood that the fourth slide groove 122d and the fifth slide groove 122e are V-shaped or arc-shaped slide grooves, which allows the first movable member 125b to achieve bidirectional line contact with the two side walls of the fourth slide groove 122d, and the second movable member 125c to achieve bidirectional line contact with the two side walls of the fifth slide groove 122e, which is beneficial for reducing frictional resistance while achieving guidance. In another embodiment, the fourth slide groove 122d, the fifth slide groove 122e, and the sixth slide groove 122f can all be rectangular slide grooves with their length direction along the second direction. The fourth slide groove 122d abuts against the first movable member 125b along a third direction, so that the first movable member 125b moves only along the second direction within the fourth slide groove 122d; the fifth slide groove 122e abuts against the second movable member 125c along a third direction, so that the second movable member 125c moves only along the second direction within the fifth slide groove 122e; the sixth slide groove 122f abuts against the third movable member 125d along a third direction, so that the third movable member 125d moves only along the second direction within the sixth slide groove 122f.

[0106] Figure 12This is a schematic diagram of the assembly structure of the carrier 121, the base 122, and the movable component 125. Some structures of the carrier 121 and the base 122 have been simplified. Figure 12 Components that are not visible to the naked eye are indicated by dashed lines.

[0107] Combination Figure 5 and Figure 12 As shown, the first movable member 125b can be accommodated in the first slide groove 121e and the fourth slide groove 122d, the second movable member 125c can be accommodated in the second slide groove 121f and the fifth slide groove 122e, and the third movable member 125d can be accommodated in the third slide groove 121g and the sixth slide groove 122f. For example, the first part 1251b of the first movable member 125b can be disposed in the first slide groove 121e, the second part 1252b of the first movable member 125b can be disposed in the fourth slide groove 122d, the third part 1251c of the second movable member 125c can be disposed in the second slide groove 121f, the fourth part 1252c of the second movable member 125c can be disposed in the fifth slide groove 122e, the fifth part 1251d of the third movable member 125d can be disposed in the third slide groove 121g, and the sixth part 1252d of the third movable member 125d can be disposed in the sixth slide groove 122f.

[0108] Combination Figure 5 and Figure 12As shown, the first movable member 125b can contact the bottom surface of the first slide groove 121e and the bottom surface of the fourth slide groove 122d; the second movable member 125c can contact the bottom surface of the second slide groove 121f and the bottom surface of the fifth slide groove 122e; and the third movable member 125d can contact the bottom surface of the third slide groove 121g and the bottom surface of the sixth slide groove 122f. For example, the dimension of the first portion 1251b along the first direction can be greater than the depth of the first slide groove 121e, and the first portion 1251b can contact the bottom surface of the first slide groove 121e; the dimension of the second portion 1252b along the first direction can be greater than the depth of the fourth slide groove 122d, and the second portion 1252b can contact the bottom surface of the fourth slide groove 122d; the dimension of the third portion 1251c along the first direction can be greater than the depth of the second slide groove 121f, and the third portion 1251c can contact the bottom surface of the second slide groove 121f. Contact; the fourth part 1252c, along the first direction, can have a dimension greater than the depth of the fifth slide groove 122e, and the fourth part 1252c can contact the bottom surface of the fifth slide groove 122e; the fifth part 1251d, along the first direction, can have a dimension greater than the depth of the third slide groove 121g, and the fifth part 1251d can contact the bottom surface of the third slide groove 121g; the sixth part 1252d, along the first direction, can have a dimension greater than the depth of the sixth slide groove 122f, and the sixth part 1252d can contact the bottom surface of the sixth slide groove 122f. By ensuring that each moving part can fully contact the bottom surface of its corresponding slide groove, the reliability of the movement of the moving part can be guaranteed. In another embodiment, whether the moving part contacts the bottom surface of its corresponding slide groove can be determined according to product requirements.

[0109] like Figure 12 As shown, the length directions of the first slide groove 121e, the second slide groove 121f, and the third slide groove 121g on the carrier 121 can all be along the third direction, and the length directions of the fourth slide groove 122d, the fifth slide groove 122e, and the sixth slide groove 122f on the base 122 can all be along the second direction. The orthographic projections of the first slide groove 121e and the fourth slide groove 122d along the first direction intersect (for example, they can be orthogonal), the orthographic projections of the second slide groove 121f and the fifth slide groove 122e along the first direction intersect (for example, they can be orthogonal), and the orthographic projections of the third slide groove 121g and the sixth slide groove 122f along the first direction intersect (for example, they can be orthogonal). This slide groove arrangement is similar to multiple "crosses" and can be called a cross slide groove.

[0110] Combination Figure 2 , Figure 4 and Figure 12As shown, when the drive assembly 123 drives the carrier 121 to move relative to the base 122 in a third direction, all moving parts can remain stationary relative to the base 122. The first moving part 125b can move in the first slide groove 121e in a third direction, the second moving part 125c can move in the second slide groove 121f in a third direction, and the third moving part 125d can move in the third slide groove 121g in a third direction, so that all moving parts are in contact with the carrier 121 in the third direction, that is, the carrier 121 can move relative to all moving parts in the third direction.

[0111] Combination Figure 2 , Figure 4 and Figure 12 As shown, when the drive assembly 123 drives the carrier 121 to move relative to the base 122 in the second direction, the carrier 121 can drive all the moving parts to move together in the second direction. The first moving part 125b can move in the second direction in the fourth slide groove 122d, the second moving part 125c can move in the second direction in the fifth slide groove 122e, and the third moving part 125d can move in the second direction in the sixth slide groove 122f, so that all the moving parts are in contact with the base 122 in the second direction, that is, the base 122 can move relative to all the moving parts in the second direction.

[0112] Combination Figure 2 , Figure 4 and Figure 12 As shown, the cross-shaped sliding grooves allow all moving parts to make contact with the carrier 121 in the third direction and with the base 122 in the second direction. This ensures that the carrier's movement in the second and third directions is independent, preventing crosstalk and improving the accuracy of the carrier's image stabilization compensation motion, thus enhancing image quality. Furthermore, the L-shaped support frame 125a divides each moving part into upper and lower sections. The upper part of each moving part makes contact with the carrier 121 in the third direction, while the lower part makes contact with the base 122 in the second direction. This allows independent movement in both directions to be achieved using only a single layer of moving parts (all moving parts are located in the same plane, with only one layer). This facilitates the thinning of the image stabilization device 12, thereby contributing to the miniaturization of the camera module 10 and the electronic device 1.

[0113] It is understood that all moving parts make contact with the carrier 121 in a third direction, and all moving parts make contact with the base 122 in a second direction; this is merely an illustrative example. In other embodiments, the directions in which all moving parts make contact with the carrier 121 and the base 122 may not be limited to those described above.

[0114] like Figure 4As shown, the drive assembly 123 is connected to the carrier 121, and the drive assembly 123 is used to drive the carrier 121 to move relative to the base in a plane (e.g., the XY plane) perpendicular to the first direction.

[0115] Figure 13 This is a schematic diagram of the assembly structure of the magnet and the carrier 121. Figure 14 This is a schematic diagram of the assembly structure of the coil and the base 122.

[0116] Combination Figure 4 , Figure 8 , Figure 10 , Figure 13 and Figure 14 As shown, exemplarily, the driving component 123 may include a first magnet 123a, a second magnet 123c, a first coil 123b, and a second coil 123d. The first magnet 123a and the second magnet 123c can be fixed to the carrier 121, for example, they can be fixed in the first groove 121c and the second groove 121d of the carrier 121, respectively; the first coil 123b and the second coil 123d can be fixed to the base 122, for example, they can be fixed in the fourth groove 122g and the third groove 122c of the base 122, respectively. The first magnet 123a and the first coil 123b are arranged opposite each other, and the second magnet 123c and the second coil 123d are arranged opposite each other.

[0117] Combination Figure 4 , Figure 13 and Figure 14 As shown, the first coil 123b is energized and interacts with the first magnet 123a, thereby driving the first magnet 123a and the carrier 121 to move along the second direction. The second coil 123d is energized and interacts with the second magnet 123c, thereby driving the second magnet 123c and the carrier 121 to move along the third direction. This helps to further reduce the crosstalk risk of the carrier 121 moving along the second direction and the third direction.

[0118] Combination Figure 4 , Figure 10 and Figure 14As shown, the drive assembly 123 may further include a first position sensor 123e and a second position sensor 123f. The first position sensor 123e may be fixed to the base 122, for example, it may be fixed in the receiving groove 1221g of the base 122. The second position sensor 123f may be fixed to the base 122, for example, it may be fixed in the receiving groove 1221c of the base 122. The first position sensor 123e and the second position sensor 123f can respectively detect the relative displacement of the first magnet 123a along the second direction and the relative displacement of the second magnet 123c along the third direction, thereby detecting the displacement of the carrier 121 relative to the base 122 along the second direction and the third direction, which is beneficial for accurately controlling the movement of the carrier 121 along the second direction and the third direction, and realizing precise image stabilization of the lens assembly 11.

[0119] Combination Figure 4 and Figure 14 As shown, for example, the first position sensor 123e and the second position sensor 123f can be Hall sensors. A Hall sensor is a semiconductor device that integrates a Hall element and signal processing circuitry onto the same integrated circuit (IC), and therefore can also be called an IC sensor. A Hall sensor can convert changes in magnetic field strength into electrical signals, thereby sensing the position of a magnet. In another embodiment, the first position sensor 123e and the second position sensor 123f can also be other types of sensors.

[0120] Combination Figures 2-14 As shown in this embodiment, by fixing at least three movable parts at intervals on the L-shaped support frame 125a, all movable parts can be fixed within the plane (e.g., the XY plane) where the support frame 125a is located. All movable parts slide within this plane, accompanied by slight rolling, suppressing any third-direction (Z-direction) torsion of the movable parts. This prevents the carrier 121 and the lens assembly 11 fixed to the carrier 121 from shaking, resulting in a more stable distance between the optical lens and the photosensitive element in the lens assembly 11, which is beneficial for improving image quality. Furthermore, the fact that these movable parts are located in the same plane facilitates the thinning of the image stabilization device 12, thereby contributing to the miniaturization of the camera module 10 and the electronic device 1.
