Description

TECHNICAL FIELD

[0001] The present application relates to the field of camera, in particular to a driving motor and related products thereof. BACKGROUND

[0002] With the popularity and development of smart phones, mobile phone photography has become a common shooting method, and users have increasingly high requirements for the shooting quality of electronic devices. Currently, long-focus lenses on the market usually adopt a periscopic structure to achieve miniaturization. The periscopic structure usually includes a light folding element and a lens group arranged from an object side to an image side, and the light folding element is driven to move by a anti-shake motor to achieve optical image stabilization. However, the driving precision of the current anti-shake motor is low, and the focal point offset is high, resulting in poor final image quality. SUMMARY

[0003] The embodiments of the present application provide a driving motor and related products comprising the same, aiming to provide a driving motor with high anti-shake precision and small focal point offset and related products thereof.

[0004] In a first aspect, a driving motor is provided. The driving motor has a light inlet hole and a light outlet hole. The driving motor comprises: a base; a first support movably connected to the base, the first support comprising a mounting slope, the mounting side of the mounting slope facing the side of the light inlet hole and the light outlet hole being a mounting side, and the mounting side being used for mounting a first optical element; and a first driving mechanism for driving the first support to rotate relative to the base about a first axis, the first axis being parallel to the mounting slope; wherein light enters the driving motor from the light inlet hole along a first direction, and after being reflected by the first optical element, the light exits the driving motor from the light outlet hole along a second direction, the first direction intersects the second direction, the first axis is located on the mounting side of the mounting slope, and the first axis is perpendicular to the plane on which the first direction and the second direction lie.

[0005] It can be understood that, compared to some driving motors driving the first optical element to rotate relative to the base about the first axis to achieve the function of optical image stabilization. Among them, the first axis is perpendicular to the plane on which the first direction and the second direction lie, and the first axis is located on the mounting slope of the mover or on the side of the mounting slope facing away from the light outlet hole. This makes the driving motor drive the first optical element to rotate about the first axis for optical image stabilization, and the focal point offset is large, which makes the modulation transfer function of the entire camera module drop greatly, the anti-shake precision is low, and the imaging quality is affected. The first axis of the driving motor in the embodiment is located on the side of the mounting slope close to the light outlet hole, that is, the mounting side of the mounting slope. The first axis is perpendicular to the plane on which the first direction and the second direction lie. In this way, when the driving motor drives the first optical element to rotate about the first axis, the focal point offset is small, thereby effectively reducing the influence of focal point offset on the modulation transfer function, which is conducive to improving the anti-shake precision of the entire camera module and improving the imaging quality.

[0006] In a possible implementation, the driving motor further includes a second support and a second driving mechanism. The second support is movably connected between the base and the first support. The second driving mechanism is configured to drive the second support and the first support to rotate relative to the base about a second axis. The second axis passes through the installation slope and is parallel to the second direction.

[0007] It can be understood that, compared to driving the first optical element to rotate about a second axis by a driving motor to realize optical image stabilization, the second axis is parallel to the first direction. Such stabilization can cause the exit surface of the first optical element to have an inclination angle with the entrance surface of a subsequent focusing assembly, thereby causing a large decline in the modulation transfer function of the entire camera module, low stabilization accuracy, and an impact on imaging quality. In the embodiment, the second axis of the driving motor is parallel to the second direction. When the first optical element rotates about the second axis to realize stabilization under the driving of the driving motor, the exit surface of the first optical element can always be parallel to the entrance surface of the subsequent focusing assembly, thereby effectively improving the overall stabilization accuracy of the driving motor, reducing the impact on the modulation transfer function, and being beneficial to improving the imaging quality of the camera module.

[0008] In a possible implementation, the first support is provided with a first connecting portion and a second connecting portion on a side close to the light exit hole. The first connecting portion is opposite to the second connecting portion and is arranged at intervals. The arrangement direction of the first connecting portion and the second connecting portion is parallel to the first axis. The driving motor further includes a first set of support members. The first set of support members includes a plurality of first support members. Part of the first support members are connected between the first connecting portion and the second support. Another part of the first support members are connected between the second connecting portion and the second support. In this way, the first connecting portion of the first support can be movably connected to the second support through part of the first support members. The second connecting portion can be movably connected to the second support through another part of the first support members. Meanwhile, the first connecting portion and the second connecting portion can be arranged close to the light exit hole, so as to arrange the first axis on the installation side of the installation slope and improve the stabilization accuracy.

[0009] In a possible implementation, the first axis passes through the first connecting portion and the second connecting portion. In this way, the distance between the first axis and the light exit hole of the driving motor is short, which is beneficial to improving the stabilization accuracy.

In this way, when the first optical element is mounted on the driving motor, the center point of the second set of support members is located on the mounting side, and the center point of the second set of support members is relatively close to the center of gravity of the first optical element, the first support, and the second support as a whole. In this way, on the one hand, the anti-interference capability of the driving motor when performing anti-shake around the second axis can be effectively enhanced; and on the other hand, the power consumption of the driving motor can be reduced, which is beneficial to prolong the endurance time of the electronic device and improve the user experience.

[0019] It can be understood that the first support frame and the second support frame are respectively provided with two sets of paired opponent grooves (i.e., the first sliding groove and the first guide groove and the second sliding groove and the second guide groove), and by arranging at least one of the first sliding groove and the second sliding groove to be a V-shaped groove, one of the first guide groove and the second guide groove to be a V-shaped groove, or at least one of the first guide groove and the second guide groove to be a V-shaped groove and one of the first sliding groove and the second sliding groove to be a V-shaped groove, the driving motor can determine the position of the first axis while avoiding the first support frame from being stuck when moving relative to the second support frame, and can also automatically correct the relative position between the actual first axis and the theoretical first axis, which is conducive to improving the smoothness of the movement of the first support frame relative to the second support frame when rotating around the first axis.

Meanwhile, the first connecting portion and the second connecting portion can be arranged close to the light exit hole, so as to facilitate to arrange the first shaft on the mounting side of the mounting inclined surface, thereby improving the anti-shake precision.

[0028] In a possible implementation manner, the driving motor further includes a bottom plate, the bottom plate includes a main body portion and an extension portion connected to each other, the main body portion is fixedly connected to a surface of the base away from the light entrance hole, and the extension portion is oppositely arranged relative to the first side wall, and an arrangement direction of the extension portion and the first side wall is parallel to the second shaft; the extension portion is provided with a first protrusion facing the first side wall, and the first side wall is provided with a first limiting groove, and at least part of the first protrusion is located in the first limiting groove.

[0030] In a possible implementation, the distance between the first shaft and the mounting slope is greater than 0.01 millimeter; and / or, the distance between the first shaft and the mounting slope is greater than or equal to 5 millimeters. In this way, the first shaft can be located on the mounting side of the mounting slope and has a certain distance from the mounting slope, which is beneficial to reduce the shift of the focal point, thereby effectively reducing the influence of the shift of the focal point on the modulation transfer function, and is beneficial to improve the anti-shake precision of the entire camera module and improve the imaging quality.

[0031] In a possible implementation, the first support is arranged in the first direction, and the first support is arranged in the second direction. The first support is provided with a first connecting portion and a second connecting portion on the side close to the light exit hole. The first connecting portion and the second connecting portion are oppositely and separately arranged, and the arrangement direction of the first connecting portion and the second connecting portion is parallel to the first shaft. The driving motor further includes a first set of support members. The first set of support members includes a plurality of first support members. The first connecting portion is rotationally connected to the base through part of the first support members, and the second connecting portion is rotationally connected to the base through another part of the first support members. In this way, the first support is directly movably connected to the base, which is beneficial to reduce the error between the first support and the base caused by assembly and the like, and improve the motion precision.

[0032] In a second aspect, an anti-shake assembly is provided. The anti-shake assembly includes a first optical element and the above-described driving motor. The first optical element includes an optical path folding element. The optical path folding element includes a first surface, a second surface, and a third surface. The first surface is perpendicular to the third surface. The second surface is arranged towards the first surface and the third surface and connects the first surface and the second surface. The first surface and the third surface are both transmissive surfaces. The second surface is a reflective surface. The first surface is oppositely arranged with the light entrance hole. The third surface is oppositely arranged with the light exit hole. The first optical element has a light entrance axis and a light exit axis. The light entrance axis is parallel to the first direction. The light exit axis is parallel to the second direction.

[0033] It can be understood that the first shaft of the driving motor of the anti-shake assembly in the embodiment is located on the side of the mounting slope close to the light exit hole, that is, the mounting side of the mounting slope. The first shaft is perpendicular to the plane in which the first direction and the second direction are located. In this way, when the driving motor drives the first optical element to rotate around the first shaft, the shift of the focal point is small, thereby effectively reducing the influence of the shift of the focal point on the modulation transfer function, and being beneficial to improve the anti-shake precision of the entire camera module and improve the imaging quality.

[0034] In a third aspect, a kind of anti-shake assemblies is provided.The anti-shake assembly includes a first optical element and the driving motor described above, the first optical element includes an optical path folding element, the optical path folding element includes a reflecting surface and a mounting surface, the reflecting surface is arranged opposite to the mounting surface, the mounting surface is towards the mounting inclined surface of the first support, and is fixedly connected with the mounting inclined surface, and the reflecting surface is arranged away from the mounting inclined surface;The first optical element has a light inlet axis and a light outlet axis, the light inlet axis is parallel to the first direction, and the light outlet axis is parallel to the second direction.

[0035] It can be understood that the first shaft of the driving motor of the anti-shake assembly in the embodiment is located on the side of the mounting inclined surface close to the light outlet hole, that is, the mounting side of the mounting inclined surface.The first shaft is perpendicular to the plane in which the first direction and the second direction lie.In this way, when the driving motor drives the first optical element to rotate around the first shaft, the displacement of the focal point is small, thereby effectively reducing the influence of the focal point displacement on the modulation transfer function, and facilitating to improve the anti-shake precision of the entire camera module and to improve the imaging quality.

[0036] Secondly, compared with the anti-shake assembly in which the optical path folding element is a reflective triangular prism, the first surface, the second surface and the third surface of the reflective triangular prism are all solid surfaces, and the transmission of light between the first surface and the third surface is located inside the reflective triangular prism.The refractive index inside the reflective triangular prism is high, so that the optical path requirement of the entire camera module increases, the focusing path of the focusing assembly is long, and the overall size of the module is large.The optical path folding element in the embodiment is a reflective plane mirror, and the reflecting surface of the optical path folding element is exposed to the air.In this way, the transmission of light between the light inlet hole and the light outlet hole is located in the air.The refractive index in the air is low, which is conducive to reducing the optical path requirement of the camera module, thereby shortening the focusing path of the focusing assembly, facilitating to reduce the size of the module in the second direction, and realizing the miniaturization of the camera module.

[0037] In a possible implementation manner, the driving motor further includes an optical mounting piece, at least a part of the optical mounting piece is fixedly connected between the optical path folding element and the mounting inclined surface, and the strength of the optical mounting piece is greater than the strength of the part where the mounting inclined surface of the first support is located.

[0038] It can be understood that, compared with the case where the optical path folding element directly contacts with the mounting inclined surface of the first support, the strength of the part where the mounting inclined surface of the first support is located is low, so that the part where the mounting inclined surface is located is prone to deformation due to impact or in a high-temperature environment, thereby affecting the surface type precision of the contact surface between the optical path folding element and the mounting inclined surface, and reducing the optical quality.The optical path folding element in the embodiment is indirectly fixed to the mounting inclined surface through the optical mounting piece, the optical path folding element does not directly contact with the mounting inclined surface, and the strength of the optical mounting piece is high, so that the optical mounting piece is not prone to deformation due to impact or in a high-temperature environment, which is conducive to ensuring the surface type precision of the contact surface between the optical path folding element and the optical mounting piece, and ensuring the optical quality of the optical path folding element.

[0039] In a possible implementation, the optical mount includes a first mount and a second mount, the first mount and the second mount are spaced apart, at least part of the first mount is fixedly connected between the optical path folding element and the mounting slope, and at least part of the second mount is fixedly connected between the optical path folding element and the mounting slope.

[0040] It can be understood that, compared with the optical mount being an integral body, that is, the first mount and the second mount are integrally formed. When the driving motor is impacted, the stress of the optical mount is relatively concentrated and is transmitted inward to the first optical element, so that the first optical element is pulled and the surface accuracy of the first optical element is affected, and the optical quality is reduced. In the embodiment, the optical mount is provided as the first mount and the second mount which are independent of each other and are separately arranged. In this way, when the driving motor is impacted, the first mount and the second mount can bear different directions of stress, respectively, so that the first optical element can be prevented from being pulled by the stress in different directions and the surface accuracy of the first optical element is reduced and the optical quality is affected.

[0041] In a possible implementation, the first optical element further includes a first lens, the first lens is located on the light-in side of the optical path folding element, and the first lens has a positive optical power. In this way, the first lens can have a light converging effect, the first lens can make as much external light as possible enter the optical path folding element, so that the light-in amount of the entire first optical element can be improved, and the light-in amount of the subsequent focusing assembly is improved.

[0042] In a possible implementation, the first optical element further includes a second lens, the second lens is located on the light-out side of the optical path folding element, and the second lens has a negative optical power. In this way, the second lens has a light diverging effect, the second lens can make as much light as possible emitted by the optical path folding element diverge, so that the light-out amount of the entire first optical element can be improved, and the light-in amount of the subsequent focusing assembly is improved.

[0043] In a possible implementation, a projection point of the first axis on a plane where the first direction and the second direction are located is a first point, and a distance between the first point and the light-out axis is less than or equal to 3 mm. In this way, the distance between the first point and the light-out axis is relatively close, and the anti-shake precision of the anti-shake assembly is improved.

[0044] In a possible implementation, the driving motor further includes a second support and a second driving mechanism, the second support is movably connected between the base and the first support, and the second driving mechanism is configured to drive the second support and the first support to rotate relative to the base about a second axis, the second axis intersects the first axis, the second axis passes through the light emitting hole and the installation slope, and is parallel to the second direction; and a distance between the second axis and the light emitting axis is less than or equal to 3 mm. In this way, the distance between the second axis and the light emitting axis is relatively small, which is beneficial to improving the anti-shake precision of the anti-shake assembly.

[0045] In a possible implementation, the driving motor further includes a second set of supports, the second support is slidably connected to the base through the second set of supports; and a distance between a center point of the second set of supports and a gravity center of the first support, the second support and the first optical element is less than or equal to 0.3 mm. In this way, the distance between the center point of the second set of supports and the gravity center of the first support, the second support and the first optical element is relatively small, which is beneficial to effectively enhancing the anti-interference capability of the driving motor when rotating about the second axis for anti-shake, and reducing the power consumption of the driving motor, thereby prolonging the endurance time of the electronic device and improving the user experience.

[0046] In a fourth aspect, a camera module is provided. The camera module includes the anti-shake assembly, a focusing assembly and an image sensor, the focusing assembly is located on the light emitting side of the anti-shake assembly, and the image sensor is located on the light emitting side of the focusing assembly. It can be understood that the first axis of the driving motor of the camera module in the embodiment is located on the side of the installation slope close to the light emitting hole, that is, the installation side of the installation slope. The first axis is perpendicular to the plane in which the first direction and the second direction lie. In this way, when the driving motor drives the first optical element to rotate about the first axis, the shift amount of the focal point is relatively small, thereby effectively reducing the influence of the focal point shift on the modulation transfer function, and improving the anti-shake precision of the entire camera module and the imaging quality.

[0047] In a fifth aspect, an electronic device is provided. The electronic device includes a device shell and the camera module described above, and the camera module is arranged on the device shell. The camera module of the electronic device in the embodiment has high anti-shake precision and high imaging quality. BRIEF DESCRIPTION OF DRAWINGS

[0113] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0114] In the description of the embodiments of the present application, it should be noted that unless specifically defined and limited, the terms "mounting", "connecting" should be interpreted broadly, for example, "connecting" can be detachable connection, or can be non-detachable connection; can be direct connection, or can be indirect connection through intermediate medium.

[0118] It can be understood that the specific embodiments described herein are merely intended to explain the related application, but not to limit the application. In addition, it should be noted that, for the convenience of description, only the parts related to the application are shown in the drawings.

[0119] Figure 20 is a structural schematic diagram of an embodiment of the electronic device 1000 provided by the present application. Figure 44 is Figure 43 is a cross-sectional structural schematic diagram of an embodiment of the electronic device 1000 shown in FIG. 1 along A-A.

[0120] As shown in FIGS. 1 and 2, the electronic device 1000 can be a device with a camera module, such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses, or VR helmet. Figure 45 As shown in FIG. 1, the electronic device 1000 of the embodiment is exemplified by a mobile phone. Figure 44 As shown in FIGS. 1 and 2, the electronic device 1000 can include a camera module 100, a device housing 200, and a screen 300. The camera module 100 can be a rear camera module or a front camera module. It should be noted that Figure 46 The drawings related below and hereinafter only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of these components are not limited by The drawings related below and hereinafter only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of these components are not limited by

[0121] In addition, when the electronic device 1000 is some other form of device, the electronic device 1000 can also not include the screen 300. Figure 44 Figure 43 to Figure 46 For the convenience of description, the width direction of the electronic device 1000 is defined as the X-axis. The length direction of the electronic device 1000 is the Y-axis. The thickness direction of the electronic device 1000 is the Z-axis. It can be understood that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs. Figure 47

[0122] For the convenience of description, the width direction of the electronic device 1000 is defined as the X-axis. The length direction of the electronic device 1000 is the Y-axis. The thickness direction of the electronic device 1000 is the Z-axis. It can be understood that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs.

[0123] ​In this embodiment, 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 integral structure.

[0124] Alternatively, the screen 300 can be located on the side of the bezel 201 away from the back cover 202. In this case, the screen and the back cover 202 are located on opposite sides of the bezel 201. The screen 300, the bezel 201, and the back cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, receiver, or microphone. The screen 300 can be a flat screen or a curved screen.

[0125] For example, the camera module 100 can be a periscope camera module. The camera module 100 can be located inside the electronic device 1000. The camera module 100 can be fixed to the side of the screen 300 facing the rear cover 202. The rear cover 202 can have a light-transmitting hole 203. The shape of the light-transmitting hole 203 is not limited to the following. Figure 10 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 its interior through the light-transmitting hole 203. The camera module 100 can capture the ambient light entering the interior of the electronic device 1000.

[0126] Figure 48 yes Figure 10 The image stabilization component of the camera module 100 shown is illustrated in some embodiments. Figure 47 yes Figure 48 The diagram shows an exploded view of the image stabilization component in some embodiments.

[0127] like Figure 49 As shown, the camera module 100 may include an image stabilization component 1, a focusing component 2, and an image sensor 3. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting hole 203, then pass sequentially through the image stabilization component 1 and the focusing component 2, and finally be imaged onto the image sensor 3. For example, the image stabilization component 1, the focusing component 2, and the image sensor 3 can be arranged sequentially along the X-axis.

[0128] In some embodiments, one or more mirrors / lenses with reflecting function can be additionally arranged between the focusing assembly 2 and the image sensor 3 to change the propagation path of the light between the focusing assembly 2 and the image sensor 3, so that the light emitted by the focusing assembly 2 can be reflected for one or more times before finally entering the image sensor 3. In this way, the light path of the camera module 100 as a whole is lengthened, which is beneficial to increase the zoom ratio of the camera module 100.

[0129] For example, the anti-shake assembly 1 can include a driving motor la and a first optical element lb. The first optical element lb can be mounted on the driving motor la. The driving motor la can realize optical image stabilization (OIS) of the camera module 100 by driving the first optical element lb to rotate around a first axis (not shown in the figure) and / or a second axis (not shown in the figure), thereby improving the imaging quality of the camera module 100.

[0130] For example, the focusing assembly 2 can include a focusing motor (not shown in the figure) and a second optical element (not shown in the figure). The second optical element can be mounted on the focusing motor. The focusing motor can control the second optical element to move along the optical axis direction for realizing auto focus (AF). The second optical element can include at least one lens. The first optical element and the second optical element can jointly constitute the optical system of the camera module 100.

[0131] Figure 20 is Figure 50 The first optical element lb of the anti-shake assembly 1 shown in the exploded structure schematic view in some embodiments. Figure 20 is Figure 49 The partial cross-sectional structure schematic view of the anti-shake assembly 1 along B1-B1 in one embodiment.

[0132] As Figure 50 and Figure 32As shown, the first optical element 1b can include an incident surface 101, a reflection surface 102, and an exit surface 103. Light rays can enter the interior of the first optical element 1b by the incident surface 101 of the first optical element 1b, be reflected by the reflection surface 102, and exit by the exit surface 103. The light-incident axis T1 of the first optical element 1b can be perpendicular to the incident surface 101. The light-exit axis T2 of the first optical element 1b can be perpendicular to the exit surface 103. In this embodiment, the light-incident axis T1 of the first optical element 1b can be parallel to the Z-axis direction, and the light-exit axis T2 can be parallel to the X-axis direction. The first optical element 1b can include a light-path folding element 104 and a first lens 105. The first lens 105 can be fixed on the light-incident side of the light-path folding element 104. At this time, the incident surface of the first lens 105 can constitute the incident surface 101 of the first optical element 1b.

[0133] Exemplarily, the light-path folding element 104 can be a reflective triangular prism. The cross section of the light-path folding element 104 can be a triangle. The light-path folding element 104 can include a first surface 1041, a second surface 1042, and a third surface 1043. The first surface 1041 and the third surface 1043 can be perpendicular to each other. The second surface 1042 can be connected between the first surface 1041 and the third surface 1043. The first surface 1041 can be perpendicular to the light-incident axis. The third surface 1043 can be perpendicular to the light-exit axis. The first surface 1041 and the third surface 1043 can both be transmission surfaces. The second surface 1042 can be a reflection surface. In this way, light rays can enter the interior of the light-path folding element 104 by the first surface 1041, be reflected by the second surface 1042, and exit by the third surface 1043. At this time, the second surface 1042 of the light-path folding element 104 can constitute the reflection surface 102 of the first optical element 1b. The third surface 1043 of the light-path folding element 104 can constitute the exit surface 103 of the first optical element 1b.

[0134] Exemplarily, the cross section of the light-path folding element 104 can be an isosceles triangle, i.e., the included angle between the second surface 1042 and the first surface 1041 can be 45°, and the included angle between the second surface 1042 and the third surface 1043 can also be 45°. At this time, the deflection angle of the light rays after being reflected by the second surface 1042 can be 90° (as shown). Figure 51 In other embodiments, the included angle between the second surface 1042 and the first surface 1041 can also be other angles, which are not limited in the present application.

[0135] For example, the first lens 105 can be located on the light-incident side of the optical path folding element 104. The first lens 105 can be fixedly connected to the first surface 1041 of the optical path folding element 104 by means of bonding or the like. The first lens 105 can be a lens with positive optical power. In this way, the first lens 105 can have a light-gathering effect, allowing as much external light as possible to enter the optical path folding element 104, thereby increasing the light intake of the entire first optical element 1b and thus improving the light intake of the subsequent focusing assembly 2.

[0136] In some embodiments, the first optical element 1b may further include a second lens 106. The second lens 106 may be a lens with negative optical power. The second lens 106 may be located on the light-emitting side of the optical path folding element 104. The second lens 106 may be fixedly connected to the third surface 1043 of the optical path folding element 104 by means of bonding or the like. In this way, the second lens 106 has a diffusing effect, which can diffuse as much light emitted from the optical path folding element 104 as possible, thereby increasing the light output of the entire first optical element 1b and improving the light intake of the subsequent focusing assembly 2. At this time, the exit surface of the second lens 106 may constitute the exit surface 103 of the first optical element 1b.

[0137] Figure 20 yes Figure 52 A simplified schematic diagram of the first optical element 1b shown. Figure 20 yes Figure 51 The diagram shows the structure from another perspective. It should be noted that... Figure 52 The first optical element 1b in the diagram only shows the optical path folding element 104 and the first lens 105, and the optical path folding element 104 only shows the second surface 1042 (that is, the reflective surface 102 of the first optical element 1b).

[0138] like Figure 53 and Figure 20As shown, the first optical element 1b can rotate (i.e. nodding motion) around the first axis R1. The plane on which the light-incoming axis T1 and the light-outgoing axis T2 lie is the reference plane M0. The first axis R1 can be perpendicular to the light-incoming axis T1 and also perpendicular to the light-outgoing axis T2, i.e. the first axis R1 can be perpendicular to the reference plane M0. The intersection of the light-outgoing axis T2 and the reflecting surface 102 is the first intersection G1. The straight line L0 intersects the edge line of the first lens 105 close to the focusing assembly 2 and is parallel to the light-incoming axis T1. The straight line L0 intersects the light-outgoing axis T2 at the second intersection G2. Exemplarily, the straight line L0 can coincide with the light-outgoing surface 103, i.e. the intersection of the light-outgoing axis T2 and the light-outgoing surface 103 is the second intersection G2. The intersection of the light-incoming axis T1 and the incident surface 101 is the third intersection G3. The intersection of the straight line L0 and the incident surface 101 is the fourth intersection G4. At this time, the first intersection G1, the second intersection G2, the third intersection G3 and the fourth intersection G4 are all on the reference plane M0. It should be understood that the first axis R1 being perpendicular to the light-incoming axis T1 can be completely perpendicular or approximately perpendicular, for example, the deviation is within 1°. The first axis R1 being perpendicular to the light-outgoing axis T2 also applies to the above definition, which will not be described here.

[0139] Exemplarily, the projection of the first axis R1 on the reference plane M0 is the first point. The first point can be located in the area defined by the straight line L1, the straight line L2 and the straight line L3. The straight line L1 and the straight line L2 are both parallel to the light-outgoing axis T2. The straight line L1 is located on the side of the light-outgoing axis T2 close to the first lens 105. The straight line L2 is located on the side of the light-outgoing axis T2 away from the first lens 105. The straight line L1 intersects the reflecting surface 102 at the k1 point. The straight line L2 intersects the reflecting surface at the k2 point. The distance of the straight line k1 and the straight line k2 to the light-outgoing axis T2 is 3mm. The straight line L3 is parallel to the light-incoming axis T1. The distance of the straight line L3 to the light-incoming axis T1 is 20mm.

[0140] It should be noted that the area defined by the straight line L1, the straight line L2 and the straight line L3 includes the area surrounded by the straight line L1, the straight line L2 and the straight line L3 and the boundary of the straight line L1, the straight line L2 and the straight line L3. In other words, the first point can be located on the image side of the reflecting surface 102, and the distance of the first point to the light-outgoing axis T2 can be less than or equal to 3mm. The distance of the first point and the second intersection G2 in the X-axis direction can be less than or equal to 20mm. In this embodiment, the first axis R1 can pass through the second intersection G2, i.e. the first axis R1 can be located on the light-outgoing surface 103 of the first optical element 1b.

[0141] Figure 54 is a simplified schematic diagram of the first optical element 1b of the anti-shake assembly 1 rotating around the first axis R1 for anti-shake in some embodiments. Figure 20 is Figure 55The first optical element 1b rotates around the first axis R1 to prevent the camera from shaking. It should be noted that Figure 20 and Figure 53 to Figure 55 The left side of the figure in the middle is a schematic diagram of the first optical element 1b shaking and the anti-shake not being turned on, and the right side of the figure is a schematic diagram of the first optical element 1b shaking and the anti-shake being turned on.

[0142] As shown in Figure 56 , ​ and ​ When the electronic device 1000 shakes in a direction parallel to the reference plane M0 and the driving motor 1a does not turn on the anti-shake, the focal point of the first optical element 1b is the first original focal point P0. It should be understood that the light emitted by the first optical element 1b will have multiple focal points, that is, the driving motor 1a has multiple first original focal points P0 when the anti-shake is not turned on, and only one of the first original focal points P0 is shown here. When the electronic device 1000 shakes in a direction parallel to the reference plane M0 and the driving motor 1a turns on the anti-shake, the driving motor 1a can drive the first optical element 1b to rotate around the first axis R1 to compensate for the image drift on the image plane caused by the shaking of the electronic device 1000, so as to achieve anti-shake.

[0143] It can be understood that in some embodiments, the first axis R1` is located on the reflecting surface 102 of the first optical element 1b, or on the side of the reflecting surface 102 facing away from the exit surface 103. However, after the first optical element 1b rotates around the first axis R1` to prevent shaking, the first focal point P1` generated by the first optical element 1b has a larger offset amount compared to the first original focal point P0, which causes the modulation transfer function (MTF) of the camera module 100 as a whole to decrease greatly, affecting the imaging quality.

[0144] In the embodiment, the first axis R1 can be located on the side of the reflecting surface 102 facing the exit surface 103, that is, on the image side of the reflecting surface 102 (on the right side of the reflecting surface 102 in ​ ). In this way, the first axis R1 is located on the side of the reflecting surface 102 of the first optical element 1b facing the exit surface 103, so that after the first optical element 1b rotates around the first axis R1 to prevent shaking, the first focal point P1 generated by the first optical element 1b has a smaller offset amount compared to the first original focal point P0, which is beneficial to improve the anti-shake precision of the camera module 100, while reducing the influence of focal point offset on the modulation transfer function, which is beneficial to improve the imaging quality.

[0145] In addition, the first axis R1 in the embodiment can pass through the second intersection G2, that is, the first axis R1 can be located on the exit surface 103 of the first optical element 1b. In this way, the focal point offset amount generated by the rotation of the first optical element 1b around the first axis R1 is smaller, which is beneficial to further reduce the influence of the focal point offset on the modulation transfer function, so as to further improve the imaging quality.

[0146] ​ is a simplified schematic diagram of the first optical element 1b in the embodiment. ​ ​ is a simplified schematic diagram of the first optical element 1b in some embodiments of the anti-shake assembly 1 rotating around the second axis R2 for anti-shake. ​ ​ is a simplified schematic diagram of the first optical element 1b rotating around the second axis R2 for anti-shake. It should be noted that, ​ In the first optical element 1b in the embodiment, only the optical path folding element 104 and the first lens 105 are shown, and the optical path folding element 104 only shows the second surface 1042 (that is, the reflection surface 102 of the first optical element 1b). ​ ​ The left side of the diagram in and the right side of the diagram in are schematic diagrams when the first optical element 1b shakes and the anti-shake is not turned on, and the right side of the diagram is a schematic diagram when the first optical element 1b shakes and the anti-shake is turned on.

[0147] As shown in ​ , the first optical element 1b can rotate around the second axis R2 (that is, a pan motion). The second axis R2 can be parallel to the light exit axis T2, that is, the second axis R2 can be parallel to the X-axis direction. The distance between the second axis R2 and the light exit axis T2 can be less than or equal to 3 mm, that is, the second axis R2 can be located within a cylindrical space with the light exit axis T2 as the central axis and a radius of 3 mm. Exemplarily, the second axis R2 can coincide with the light exit axis T2. It should be understood that the second axis R2 can be parallel to the light exit axis T2, which can be completely parallel or approximately parallel, for example, the deviation is within 1°. When the electronic device 1000 shakes in a direction parallel to the reference plane M0 and the anti-shake of the first optical element 1b is not turned on, the exit surface M1 of the anti-shake assembly 1 can be parallel to the entrance surface M2 of the focusing assembly 2. The exit surface M1 of the anti-shake assembly 1 is parallel to the exit surface 103 of the first optical element 1b. When the driving motor 1a turns on the anti-shake, the driving motor 1a can drive the first optical element 1b to rotate around the second axis R2 to compensate for the image drift on the image plane caused by the shaking of the electronic device 1000, so as to realize anti-shake.

[0148] ​​​It can be understood that, in some embodiments, the second axis R2` coincides with the light entrance axis G1 of the first optical element 1b, that is, the second axis R2` can be parallel to the Z-axis direction. However, when the first optical element 1b rotates around the second axis R2`, the exit surface M1` of the anti-shake assembly 1 forms an angle with the entrance surface M2 of the focusing assembly 2, so that the first optical element 1b and the focusing assembly 2 have a large inclination angle, the optical quality of the camera module 100 decreases greatly, the imaging quality is low, and the focus offset is large, so that the modulation transfer function of the camera module 100 as a whole decreases greatly, affecting the imaging quality.

[0149] In the embodiment, the second axis R2 can be parallel to the light exit axis T2, that is, the second axis R2 can be perpendicular to the exit surface 103 of the first optical element 1b and the entrance surface M2 of the focusing assembly 2. In this way, when the first optical element 1b rotates around the second axis R2, the exit surface M1 of the anti-shake assembly 1 can always be parallel to the light exit axis T2 and perpendicular to the entrance surface M2 of the focusing assembly 2, thereby effectively reducing the inclination angle between the first optical element 1b and the focusing assembly 2, improving the anti-shake precision of the camera module 100, and the optical quality of the camera module 100 decreases less, and the focus offset is small, which is beneficial to reducing the influence of the focus offset on the modulation transfer function, thereby improving the imaging quality of the camera module 100.

[0150] In addition, the distance between the second axis R2 and the light exit axis T2 can be less than or equal to 3 mm, so that the second axis R2 can be arranged close to the light exit axis T2, thereby better reducing the influence of the focus offset on the modulation transfer function, and being beneficial to improving the imaging quality of the camera module 100.

[0151] Please refer to ​ , ​ and ​ It can be understood that, compared with a camera module in which a reflecting prism is additionally arranged between a focusing assembly and an image sensor, and the optical anti-shake is realized by controlling the displacement of the image sensor, the module volume is large. In the camera module 100 of the embodiment, the driving motor 1a is arranged to drive the first optical element 1b to rotate around the first axis R1 and / or the second axis R2, so as to realize the optical image anti-shake of the entire camera module 100, thereby not needing to additionally arrange a prism between the focusing assembly 2 and the image sensor 3, the module volume is small, and it is beneficial to realize the miniaturization of the camera module 100.

[0152] Secondly, in this embodiment, the first axis R1 is perpendicular to both the input optical axis T1 and the output optical axis T2 (i.e., parallel to the Y-axis in this embodiment), and is located on the side of the reflective surface 102 of the first optical element 1b closest to the output surface 103, i.e., the image side of the reflective surface 102. The second axis R2 is parallel to the output optical axis T2. In this way, whether the first optical element 1b rotates around the first axis R1 or around the second axis R2, the focal point shift is small. At the same time, the output surface M1 of the image stabilization component 1 can always remain parallel to the incident surface M2 of the focusing component 2, thereby effectively improving the image stabilization accuracy of the camera module 100, reducing the impact of focal point shift and tilt angle on the overall modulation transfer function of the camera module 100, and improving the imaging quality of the camera module 100.

[0153] In other words, the camera module 100 in this embodiment performs image stabilization by controlling the first optical element 1b to rotate around the first axis R1 and / or the second axis R2. The first axis R1 is parallel to the Y-axis direction, the second axis R2 is parallel to the X-axis direction, and the first axis R1 is located on the side of the reflective surface 102 facing the output surface 103 (that is, the image side of the reflective surface 102). This makes the focus shift of the camera module 100 small when performing optical image stabilization, thereby achieving high image stabilization accuracy and good image quality.

[0154] The above text describes the structure of the electronic device 1000, the structure of the camera module 100, and the image stabilization principle of the first optical element 1b of the camera module 100. The following text will describe the structure of the drive motor 1a in the camera module 100 in detail with reference to the relevant figures.

At this time, the first portion 521 can semi-enclose the first connecting portion 515. In this way, the structure of the first portion 521 and the first connecting portion 515 is more compact, which is conducive to achieving the miniaturization of the driving motor la.

[0213] For example, two of the third guide groove 5215, the fourth guide groove 5216, the fifth guide groove 5225, and the sixth guide groove 5226 can be "V"-shaped grooves. This ensures that, on the one hand, two of the third guide groove 5215, the fourth guide groove 5216, the fifth guide groove 5225, and the sixth guide groove 5226 being "V"-shaped grooves can automatically correct the relative position between the actual third rotation center O3 and the theoretical third rotation center O3, thereby making the rotation of the second support 52 relative to the base 10 smoother; on the other hand, it also avoids the second support 52 from jamming when rotating relative to the base 10 if all three of the third guide groove 5215, the fourth guide groove 5216, the fifth guide groove 5225, and the sixth guide groove 5226 are "V"-shaped grooves.

The third side portion 13 of the base 10 can partially surround the second portion 522 of the second bracket 52.

The reflecting surface 102 of the first optical element 1b can face the mounting slope 511a of the first support 51. It should be noted that when the first optical element 1b is mounted on the first support 51, the reflecting surface 102 of the first optical element 1b is opposite to the mounting slope 511a, the reflecting surface 102 of the first optical element 1b and the mounting slope 511a can be in contact or there is a small gap. The small gap can be formed by an air gap or the thickness of a fixing member (such as an adhesive layer or the like). At this time, the small gap between the reflecting surface 102 and the mounting slope 511a can be ignored, and the reflecting surface 102 and the mounting slope 511a are considered to be coincident. That is, the first axis R1 can be located on the side of the reflecting surface 102 close to the light exit hole 20b.

[0218] Exemplarily, the light entrance axis T1 of the first optical element 1b can pass through the light entrance hole 20a and the mounting slope 511a.

The distance between the third rotation center O3 and the center of gravity of the mover 50 and the first optical element 1b as a whole can be less than or equal to 0.3 millimeter. It should be noted that the center of gravity of the mover 50 and the first optical element 1b as a whole can also be approximately considered as the center of gravity of the first support 51, the second support 52 and the first optical element 1b as a whole of the mover 50.

Wherein the direction of the first driving force is opposite to the direction of the second driving force, so as to drive the first support 51 to rotate relative to the base 10 around the second axis R2 together with the second support 52, that is, the first support 51 can drive the second support 52 to rotate relative to the stator around the second axis R2. At this time, the second set of magnetic pieces 54 and the second driving coil 322 can jointly constitute a second driving mechanism of the driving motor 1a. The first sensor 331 can cooperate with the first sub-magnetic piece 541, and the third sensor 333 can cooperate with the second sub-magnetic piece 542 to jointly detect the magnetic field intensity when the first support 51 rotates around the second axis R2 at different angles, so as to detect the angle of rotation of the first support 51 around the second axis R2. In other words, the first optical element 1b can rotate relative to the stator around the second axis R2 under the action of the mover 50, so as to realize anti-shake.

[0224] It can be understood that, compared with driving the mover of the driving motor to drive the first optical element to rotate relative to the stator around the first axis and rotate around the second axis to realize the optical image anti-shake function. Among them, the first axis is parallel to the Y-axis direction. The first axis is located on the installation slope of the mover, or on the side of the installation slope away from the light exit hole. The second axis is parallel to the Z-axis direction. This makes the driving motor drive the first optical element to rotate around the first axis and / or rotate around the second axis for optical image anti-shake, the displacement of the focal point is relatively large, the modulation transfer function of the entire camera module decreases greatly, the anti-shake precision is relatively low, and the imaging quality is affected. The first axis R1 of the driving motor 1a in the embodiment is located on the side of the installation slope 511a close to the light exit hole 20b, that is, the installation side 51b of the installation slope 511a. The first axis R1 is parallel to the Y-axis direction. In this way, when the mover 50 of the driving motor 1a drives the first optical element 1b to rotate around the first axis R1, the displacement of the focal point is small, thereby effectively reducing the influence of focal point displacement on the modulation transfer function, which is conducive to improving the anti-shake precision of the entire camera module 100 and improving the imaging quality. At the same time, the mover 50 drives the first optical element 1b to rotate relative to the stator around the second axis R2, and the second axis R2 is parallel to the X-axis direction. In this way, when the mover 50 of the driving motor 1a drives the first optical element 1b to rotate around the second axis R2, the exit surface of the anti-shake assembly 1 can always be perpendicular to the light exit axis T2, thereby effectively reducing the inclination angle between the anti-shake assembly 1 and the focusing assembly 2, reducing the displacement of the focal point, and improving the anti-shake precision of the entire camera module 100. The optical quality of the camera module 100 is high, which is conducive to improving the imaging quality.

[0225] In other words, by setting the first axis R1 parallel to the Y-axis direction, the second axis R2 parallel to the X-axis direction, and the first axis R1 on the installation side 51b of the installation slope 511a of the mover 50, the driving motor 1a in the embodiment can effectively improve the anti-shake precision of the driving motor 1a as a whole, reduce the influence on the modulation transfer function, and improve the imaging quality of the camera module 100.

[0226] Secondly, the third rotation center O3 of the mover 50 of the driving motor 1a in the embodiment when driving the stator to rotate around the second axis R2 is located on the installation side 51b of the installation slope 511a of the mover 50, so that the third rotation center O3 can be closer to the center of gravity of the mover 50 and the first optical element 1b as a whole. In this way, on the one hand, the anti-interference ability of the driving motor 1a when rotating around the second axis R2 for anti-shake can be effectively enhanced; on the other hand, the power consumption of the driving motor 1a can also be reduced, which is conducive to prolonging the endurance time of the electronic equipment 1000 and improving the user experience. The distance between the third rotation center O3 and the center of gravity of the mover 50 and the first optical element 1b as a whole can be less than or equal to 0.03 millimeters.

[0227] In addition, compared with the first shaft being parallel to the Y-axis direction, the first shaft is located on the installation slope of the mover or on the side of the driving motor facing away from the light exit hole. In the present embodiment, the first shaft R1 of the driving motor 1a is located on the installation side 51b of the installation slope 511a, so that the distance between the first set of magnetic components 53 and the first shaft R1 can be increased, that is, the driving force arm when the first set of magnetic components 53 drives the first support 51 to rotate around the first shaft R1 relative to the second support 52. In this way, under the condition that the total weight of the mover 50 and the first optical element 1b is the same, the driving motor 1a of the present embodiment can generate greater thrust to prevent shake and achieve large-angle anti-shake. Under the condition that the anti-shake angle is the same, the mover 50 of the driving motor 1a of the present embodiment can carry a first optical element 1b with a greater weight, which is beneficial to improve the optical quality of the entire camera module 100.

[0228] In addition, in the present embodiment, the plurality of sets of magnetic components (in the present embodiment, the first set of magnetic components 53 and the second set of magnetic components 54) of the driving motor 1a are all arranged on the first support 51, so that integrated transmission can be achieved, which is beneficial to improve the smoothness of the driving motor 1a when performing anti-shake.

[0229] In some embodiments, the end of the third side wall 514 of the first support 51 away from the light entrance hole 20a can be provided with a bump stop 5142 ​ and ​ The bump stop 5142 is also schematically shown from another perspective. The second side 12 of the base 10 can be provided with a limiting hole 122 ​ The limiting hole 122 is also schematically shown from another perspective. At least part of the bump stop 5142 of the first support 51 can be located in the limiting hole 122 of the base 10. In this way, when the first support 51 rotates around the first shaft R1 relative to the base 10, the bump stop 5142 can cooperate with the limiting hole 122, so as to effectively avoid the angle of rotation of the first support 51 around the first shaft R1 relative to the base 10 being too large, causing the first optical element 1b to collide with the stator of the driving motor 1a and be damaged, which is beneficial to prolong the service life of the camera module 100.

[0230] In other embodiments, as ​ and ​As shown, the extension portion 222 of the base plate 22 may be provided with a first protrusion 2221 and a second protrusion 2222. The first protrusion 2221 may be disposed toward the first sidewall 512 of the first bracket 51. The second protrusion 2222 may be disposed toward the second sidewall 513 of the first bracket 51. The first sidewall 512 of the first bracket 51 may be provided with a first limiting groove 512a. At least a portion of the first protrusion 2221 may be located within the first limiting groove 512a. The second sidewall 513 of the first bracket 51 may be provided with a second limiting groove 513a. At least a portion of the second protrusion 2222 may be located within the second limiting groove 513a. Thus, when the first bracket 51 is under the action of the second bracket 52, it rotates relative to the stator around the second axis R2 (please refer to...). ​ When rotating, the first protrusion 2221 can engage with the first limiting groove 512a, and the second protrusion 2222 can engage with the second limiting groove 513a. This can effectively prevent the first bracket 51 from rotating too much relative to the stator around the second axis R2, which would cause the first optical element 1b to collide with the stator of the drive motor 1a and be damaged. This is beneficial to extending the service life of the camera module 100.

[0232] like ​ and ​ As shown, the structure of the drive motor 1a in this embodiment is similar to... ​The structure of the driving motor 1a shown is substantially the same, and the same parts will not be described again. The difference is that the first group of magnetic pieces 53 of the driving motor 1a in this embodiment can further include a third magnet 533. The third magnet 533 can be located between the first magnet 531 and the second magnet 532. The first magnet 531, the third magnet 533, and the second magnet 532 can be arranged in sequence along the Z-axis direction. The third magnet 533 can be a single-pole magnetized magnet. The polarization direction of the third magnet 533 can be perpendicular to the polarization direction of the first magnet 531. For example, the part of the first magnet 531 facing the first side wall 512 is S-pole, and the part of the first magnet 531 away from the first side wall 512 is N-pole. The part of the second magnet 532 facing the first side wall 512 can be S-pole. The part of the second magnet 532 away from the first side wall 512 can be N-pole. The part of the third magnet 533 facing the first magnet 531 can be N-pole. The part of the third magnet 533 facing the second magnet 532 can be S-pole. At this time, the plurality of magnets of the first group of magnetic pieces 53 (in this embodiment, the first magnet 531, the second magnet 532, and the third magnet 533) can form a Halbach array.

[0233] It can be understood that the first group of magnetic pieces 53 in this embodiment adopts a Halbach array to arrange a plurality of magnets. In the case of the same overall size of the first group of magnetic pieces 53, the first group of magnetic pieces 53 in this embodiment generates a larger driving force with the first driving coil 321. In this way, under the condition that the total weight of the mover 50 and the first optical element 1b is the same, the mover 50 of this embodiment can drive the first optical element 1b to rotate a larger angle around the first axis R1 (see ​ ) to achieve large-angle anti-shake. Under the condition of the same rotation angle, the mover 50 in this embodiment can carry a first optical element 1b with a larger weight, which is beneficial to improve the optical quality of the entire camera module 100.

[0234] In some embodiments, the first sub-magnetic piece 541 and the second sub-magnetic piece 542 of the second group of magnetic pieces 54 can also adopt a Halbach array to arrange a plurality of magnets. The magnetic field direction of the first sub-magnetic piece 541 can be opposite to the magnetic field direction of the second sub-magnetic piece 542. The structure of the first sub-magnetic piece 541 and the second sub-magnetic piece 542 is substantially the same as that of the first group of magnetic pieces 53, and the same parts will not be described again.

[0235] In some embodiments, the first set of magnetic elements 53 can also cooperate with the first drive coil 321 to generate a driving force parallel to the Y-axis, thereby driving the first bracket 51 to rotate relative to the base 10 around the second axis R2, causing the second bracket 52 to rotate together. In this case, the first set of magnetic elements 53 and the first drive coil 321 together constitute the second drive mechanism of the drive motor 1a. The first sub-magnetic element 541 of the second set of magnetic elements 54 can also cooperate with the first sub-coil 3221 of the second drive coil 322 to generate a first driving force along the Z-axis. The second sub-magnetic element 542 of the second set of magnetic elements 54 can also cooperate with the second sub-coil 3222 of the second drive coil 322 to generate a second driving force along the Z-axis. The direction of the first driving force is the same as the direction of the second driving force. Thus, the first sub-magnetic element 541 and the second sub-magnetic element 542 of the second set of magnetic elements 54 can respectively cooperate with the first sub-coil 3221 and the second sub-coil 3222 to jointly drive the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1. At this time, the second set of magnetic components 54 and the second drive coil 322 can together form the first drive mechanism of the drive motor 1a.

[0236] In other embodiments, the first set of magnetic elements 53 and the first driving coil 321 can be disposed on the side of the first bracket 51 facing away from the light-entry hole 20a. The first set of magnetic elements 53 can generate a driving force along the X-axis with the first driving coil 321, thereby driving the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1. Alternatively, without changing the positions of the first set of magnetic elements 53 and the first driving coil 321, a fourth set of magnetic elements and a third driving coil can be disposed on the side of the first bracket 51 facing away from the light-entry hole 20a. The fourth set of magnetic elements can cooperate with the third driving coil to generate a driving force along the X-axis. In this way, the first set of magnetic elements 53 and the fourth set of magnetic elements can cooperate with the first driving coil 321 and the third driving coil respectively to jointly drive the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1, which is beneficial to increasing the driving force of the first bracket 51 rotating relative to the second bracket 52 and achieving large-angle image stabilization.

[0237] ​ yes ​ The diagram shows a cross-sectional structure of another embodiment of the image stabilization component 1 cut along B1-B1. ​ yes ​ The diagram shows a partial exploded view of the image stabilization component 1.

[0238] like ​ and ​ As shown, the structure of the image stabilization component 1 in this embodiment is similar to... ​The structures of the anti-shake assemblies 1 shown are substantially the same, and the same parts will not be described again. The differences between the two will be mainly introduced below. The light path folding element 104 of the anti-shake assembly 1 in this embodiment can be a reflecting plane mirror. The reflecting plane mirror can include a reflecting surface 1044 and a mounting surface 1045 arranged opposite to each other. The reflecting surface 1044 of the reflecting plane mirror can be directed towards the light inlet hole 20a and the light outlet hole 20b. The mounting surface 1045 of the light path folding element 104 can be directed towards the mounting inclined surface 511a of the first support 51. The mounting surface 1045 of the light path folding element 104 can be fixedly connected to the mounting inclined surface 511a of the first support 51. The reflecting surface 1044 of the light path folding element 104 can be arranged at an angle with the surface of the first lens 105 directed towards the light path folding element 104. For example, the reflecting surface 1044 can be arranged at an angle of 45° with the surface of the first lens 105 directed towards the light path folding element 104. At this time, the reflecting surface 1044 of the reflecting plane mirror can constitute the reflecting surface 102 of the first optical element 1b.

[0239] It can be understood that, compared with the anti-shake assembly in which the light path folding element is a reflecting triangular prism, the first surface, the second surface and the third surface of the reflecting triangular prism are all solid surfaces, and the transmission of the light between the first surface and the third surface is located inside the reflecting triangular prism. The refractive index inside the reflecting triangular prism is high, which increases the optical path requirement of the entire camera module, the focusing path of the focusing assembly is long, and the overall size of the module is long. In this embodiment, the light path folding element 104 is a reflecting plane mirror, and the reflecting surface 1044 of the light path folding element 104 is exposed to the air. In this way, the transmission of the light between the light inlet hole 20a and the light outlet hole 20b is located in the air. The refractive index in the air is low, which is beneficial to reduce the optical path requirement of the camera module 100, so as to shorten the focusing path of the focusing assembly 2, which is beneficial to reduce the size of the module in the X-axis direction, and realize the miniaturization of the camera module 100.

[0240] In some embodiments, as shown in ​ , ​ is ​ the assembly structure of the first optical element 1b of the anti-shake assembly 1 shown and the optical mounting member 70. ​ is ​ the cross-sectional structure of the assembly structure of the optical mounting member 70 and part of the structure of the driving motor 1a of the anti-shake assembly 1 shown.

[0241] Exemplarily, the driving motor 1a can further include an optical mount 70. The optical mount 70 can be a steel sheet. The strength of the optical mount 70 can be greater than the strength of the portion where the mounting slope 511a of the first support 51 is located. At least a portion of the optical mount 70 can be located between the optical path folding element 104 and the mounting slope 511a. In other words, the optical path folding element 104 can be indirectly fixed to the mounting slope 511a through the optical mount 70. In this way, compared with the case where the optical path folding element 104 is directly in contact with the mounting slope 511a of the first support 51, the strength of the portion where the mounting slope 511a of the first support 51 is located is lower, so that the portion where the mounting slope 511a is located is prone to deformation due to impact or in a high-temperature environment, thereby affecting the surface type accuracy of the contact surface (in this embodiment, the mounting surface 1045 of the optical path folding element 104) between the optical path folding element 104 and the mounting slope 511a, and reducing the optical quality. In this embodiment, the optical path folding element 104 is indirectly fixed to the mounting slope 511a through the optical mount 70, the optical path folding element 104 is not in direct contact with the mounting slope 511a, and the strength of the optical mount 70 is higher, so that the optical mount 70 is not prone to deformation due to impact or in a high-temperature environment, which is conducive to ensuring the surface type accuracy of the contact surface (in this embodiment, the mounting surface 1045 of the optical path folding element 104) between the optical path folding element 104 and the optical mount 70, and ensuring the optical quality of the optical path folding element 104. In other embodiments, the optical mount 70 can also be a glue layer. The optical path folding element 104 can be fixed to the mounting slope 511a through the optical mount 70.

[0242] Exemplarily, the optical mount 70 can include a first mount 71 and a second mount 72. The first mount 71 can include a first limiting portion 711, a second limiting portion 712, a connecting portion 713, and a mounting portion 714. The first limiting portion 711 of the first mount 71 can be fixedly connected to the surface of the first support 51 facing away from the bottom 10b of the base 10. The second limiting portion 712 of the first mount 71 can be fixedly connected to the surface of the first side wall 512 of the first support 51 facing away from the third side wall 514. The mounting portion 714 of the first mount 71 can be fixedly connected to the mounting inclined surface 511a of the first support 51. The connecting portion 713 of the first mount 71 can be connected between the first limiting portion 711, the second limiting portion 712, and the mounting portion 714. It should be understood that the structure of the second mount 72 is substantially the same as that of the first mount 71, and the same parts will not be described again. The second limiting portion 712 of the second mount 72 can be fixedly connected to the surface of the second side wall 513 facing away from the third side wall 514. The mounting surface 1045 of the optical path folding element 104 can be fixedly connected to the surface of the mounting portion 714 of the first mount 71 facing away from the mounting inclined surface 511a and the surface of the mounting portion 724 of the second mount 72 facing away from the mounting inclined surface 511a. The first lens 105 can be fixedly connected to the first limiting portion 711 of the first mount 71 and the first limiting portion 721 of the second mount 72.

[0243] It can be understood that, compared to the optical mount 70 being an integral body, that is, the first mount 71 and the second mount 72 are integrally formed. When the driving motor 1a is impacted, the stress of the optical mount 70 is more concentrated and is transmitted inward to the first optical element 1b, causing the first optical element 1b to be pulled, affecting the surface accuracy of the first optical element 1b and reducing the optical quality. In the present embodiment, the optical mount 70 is provided as the first mount 71 and the second mount 72 which are independent of each other and are separately arranged. In this way, when the driving motor 1a is impacted, the first mount 71 and the second mount 72 can bear different directions of stress, respectively, so that the first optical element 1b can be prevented from being pulled by different directions of stress, thereby reducing the surface accuracy of the first optical element 1b and affecting the optical quality.

[0244] Secondly, the optical mount 70 is arranged in cooperation with the first support 51 through a plurality of limiting portions, which on the one hand increases the fixing area of the optical mount 70, the first support 51, and the first optical element 1b, and is beneficial to improving the structural stability among the optical mount 70, the first optical element 1b, and the mover 50; on the other hand, the arrangement of the plurality of limiting portions is also beneficial to the positioning and assembly among the optical mount 70, the first optical element 1b, and the mover 50, and is beneficial to improving the assembly accuracy.

[0245] Exemplarily, the connecting portion 713 of the first mounting member 71 can be bent in a direction away from the mounting portion 714. At this time, the connecting portion 713 of the first mounting member 71 can be bent to be substantially in a "U" shape. The first bracket 51 can further be provided with a fourth avoiding hole 517. A part of the connecting portion 713 of the first mounting member 71 can be located in the fourth avoiding hole 517. In this way, by bending the part of the first mounting member 71, the first mounting member 71 can further have the functions of buffering and releasing stress, so as to effectively improve the structural stability of the whole anti-shake assembly 1. Meanwhile, the first bracket 51 is further provided with the fourth avoiding hole 517 for avoiding the connecting portion 713 of the first mounting member 71, so that the structure between the first mounting member 71 and the first bracket 51 is more compact, which is beneficial to realize the miniaturization of the driving motor la.

[0246] Exemplarily, the connecting portion 713 of the second mounting member 72 can be bent in a direction away from the mounting portion 714. At this time, the connecting portion 713 of the second mounting member 72 can also be bent to be substantially in a "U" shape. The first bracket 51 can further be provided with a fifth avoiding hole 518. A part of the connecting portion 713 of the second mounting member 72 can be located in the fifth avoiding hole 518.

[0247] In some embodiments, the connecting portion 713 of the first mounting member 71 can be provided with one or more through holes, so that the first mounting member 71 can better buffer and release stress.

[0248] The above describes an embodiment of the mover 50 of the driving motor la and the setting of the driving motor la including the mover 50 in various anti-shake assemblies 1 in detail in combination with the related drawings. The following will introduce several setting modes of the mover 50 of the driving motor la in combination with the related drawings.

[0250] As ​As shown, the first bracket 51 in the embodiment can also not be provided with the first mounting slot and the second mounting slot. The second bracket 52 can also be provided with a fourth mounting slot 5217 and a fifth mounting slot 5227. The fourth mounting slot 5217 can be arranged at the middle portion 5212 of the first portion 521 of the second bracket 52. The opening of the fourth mounting slot 5217 can be formed on the surface of the middle portion 5212 of the first portion 521 facing away from the second portion 522. The fifth mounting slot 5227 can be arranged at the middle portion 5222 of the second portion 522 of the second bracket 52. The opening of the fifth mounting slot 5227 can be formed on the surface of the middle portion 5222 of the second portion 522 facing away from the first portion 521. In some embodiments, the mover 50 can also include a magnetic conducting member 58. The magnetic conducting member 58 can be fixed to the third mounting slot 5141 of the first bracket 51.

[0251] Exemplarily, the mover 50 can also include a second reinforcing member 59. The second reinforcing member 59 can be a steel sheet. The second reinforcing member 59 can have magnetic conductivity. The second reinforcing member 59 can be embedded in the interior of the second bracket 52 by injection molding or the like. Part of the second reinforcing member 59 can be exposed through the fourth mounting slot 5217 and the fifth mounting slot 5227.

[0253] As ​ and ​ As shown, the first sub-magnetic member 541 and the second sub-magnetic member 542 of the second group of magnetic members 54 can be fixed to the second bracket 52 and located in the fourth mounting slot 5217 and the fifth mounting slot 5227, respectively. The first group of magnetic members 53 can be fixed to the first bracket 51 and located in the third mounting slot 5141. At this time, the first group of magnetic members 53 can be arranged in the second direction (i.e., the X-axis direction in the embodiment) with the mounting inclined surface 511a of the first bracket 51. The first sub-magnetic member 541, the mounting inclined surface 511a of the first bracket 51, and the second sub-magnetic member 542 can be arranged in the third direction (i.e., the Y-axis direction in the embodiment) in sequence.

[0254] When the first driving coil 321 is applied with a signal, the first set of magnetic pieces 53 can cooperate with the first driving coil 321 to generate a driving force along the direction of the Z axis, so as to drive the first support 51 to rotate relative to the second support 52 around the first axis R1, that is, the first support 51 rotates relative to the stator around the first axis R1. In other words, the first optical element 1b can rotate relative to the stator around the first axis R1 under the action of the mover 50, so as to realize anti-shake.

[0255] When the second driving coil 322 is applied with a signal, the first sub-magnetic piece 541 of the second set of magnetic pieces 54 can cooperate with the first sub-coil 3221 of the second driving coil 322 to generate a first driving force along the direction of the Z axis. The second sub-magnetic piece 542 of the second set of magnetic pieces 54 can cooperate with the second sub-coil 3222 of the second driving coil 322 to generate a second driving force along the direction of the Z axis. The direction of the first driving force is opposite to the direction of the second driving force, so as to drive the second support 52 to rotate relative to the base 10 around the second axis R2 together with the first support 51, that is, the second support 52 can drive the first support 51 to rotate relative to the stator around the second axis R2. In other words, the first optical element 1b can rotate relative to the stator around the second axis R2 under the action of the mover 50, so as to realize anti-shake.

[0256] It can be understood that in the embodiment, the second set of magnetic pieces 54 of the mover 50 is fixed to the second support 52, so that the driving force generated by the cooperation between the second set of magnetic pieces 54 and the second driving coil 322 can directly act on the second support 52, and is not interfered by the assembly error between the first support 51 and the second support 52, which is beneficial to improving the anti-shake precision of the driving motor 1a.

[0258] As ​ and ​ shown, the number of the first ball 551 in the embodiment can be one. The first connecting part 515 of the first support 51 can be rotatably connected to the first part 521 of the second support 52 through the first ball 551. Exemplarily, the first ball 551 can be fixed in the first guide groove 5214 of the first part 521. Part of the first ball 551 can be located in the first sliding groove 5152 of the first connecting part 515.

[0259] Exemplarily, the mover 50 can further include a first magnetic piece 5191 and a second magnetic piece 5192. The first magnetic piece 5191 and the second magnetic piece 5192 can have the same shape and size. The first magnetic piece 5191 and the second magnetic piece 5192 can be fixed to the first connecting portion 515 of the first support 51 (for example, the first magnetic piece 5191 and the second magnetic piece 5192 are embedded in the first connecting portion 515).
