Technical Field

[0002] The present application relates to the field of imaging, and in particular to a drive motor and related products. Background Art

[0003] With the widespread adoption and development of smartphones, mobile photography has become a common method of photography, and users are demanding increasingly high quality photography from their electronic devices. Currently, telephoto lenses on the market typically employ a periscope-style design to achieve miniaturization. This design typically consists of a light-folding element and lens array arranged from the object side to the image side, with an anti-shake motor driving the light-folding element to achieve optical image stabilization. However, current anti-shake motors suffer from low drive precision, resulting in high focus offsets and poor image quality.

[0004] Summary of the Invention

[0005] The embodiments of the present application provide a drive motor and related products including the drive motor, aiming to provide a drive motor and related products with high anti-shake accuracy and small focus offset.

[0006] In the first aspect, a driving motor is provided. The driving motor has a light inlet and a light outlet. The driving motor comprises: a base; a first bracket movably connected to the base, the first bracket comprising a mounting bevel, the side of the mounting bevel facing the light inlet and the light outlet being the mounting side, the mounting side being used to mount the first optical element; and a first driving mechanism, for driving the first bracket to rotate around a first axis relative to the base, the first axis being parallel to the mounting bevel; wherein light enters the driving motor from the light inlet along a first direction, and after being reflected by the first optical element, the light exits the driving motor from the light outlet along a second direction, the first direction intersects the second direction, the first axis is located on the mounting side of the mounting bevel, and is perpendicular to the plane where the first direction and the second direction are located.

[0007] It can be understood that compared to some driving motors driving the first optical element to rotate relative to the base around the first axis to achieve the optical image stabilization function. Among them, the first axis is perpendicular to the plane where the first direction and the second direction are located, and the first axis is located on the mounting bevel of the mover, or on the side of the mounting bevel facing away from the light exit hole. This makes the focus offset larger when the driving motor drives the first optical element to rotate around the first axis for optical image stabilization, causing the modulation transfer function of the entire camera module to drop significantly, and the anti-shake accuracy is low, affecting the imaging quality. The first axis of the driving motor in this embodiment is located on the side of the mounting bevel close to the light exit hole, that is, the mounting side of the mounting bevel. The first axis is perpendicular to the plane where 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 axis, the focus offset is smaller, thereby effectively reducing the influence of the focus offset on the modulation transfer function, which is beneficial to improving the anti-shake accuracy of the entire camera module and improving the imaging quality.

[0008] In one possible implementation, the drive motor also includes a second bracket and a second drive mechanism, the second bracket is movably connected between the base and the first bracket, and the second drive mechanism is used to drive the second bracket and the first bracket to rotate around a second axis relative to the base, and the second axis passes through the mounting bevel and is parallel to the second direction.

[0009] It is understandable that, compared to some drive motors driving the first optical element to rotate around the second axis to achieve the optical image stabilization function, the second axis is parallel to the first direction. Such anti-shake will cause the exit surface of the first optical element and the incident surface of the subsequent focusing component to have an inclination angle, thereby causing the modulation transfer function of the entire camera module to drop significantly, the anti-shake accuracy is low, and the imaging quality is affected. In this embodiment, the second axis of the drive motor is parallel to the second direction. When the first optical element rotates around the second axis for anti-shake under the drive of the drive motor, the exit surface of the first optical element can always remain parallel to the incident surface of the subsequent focusing component, thereby effectively improving the overall anti-shake accuracy of the drive motor, reducing the impact on the modulation transfer function, and helping to improve the imaging quality of the camera module.

[0010] In one possible implementation, a first connecting portion and a second connecting portion are provided on a side of the first bracket close to the light exit hole, the first connecting portion and the second connecting portion are opposite to each other and spaced apart, and the arrangement direction of the first connecting portion and the second connecting portion is parallel to the first axis. The drive motor also includes a first group of supports, the first group of supports includes a plurality of first supports, some of the first supports are connected between the first connecting portion and the second bracket, and another part of the first supports are connected between the second connecting portion and the second bracket. In this way, the first connecting portion of the first bracket can be movably connected to the second bracket through a part of the first supports, and the second connecting portion can be movably connected to the second bracket through another part of the first supports. At the same time, both the first connecting portion and the second connecting portion can be arranged close to the light exit hole, so that the first axis can be arranged on the mounting side of the mounting slope to improve the anti-shake accuracy.

[0011] In one possible implementation, the first shaft passes through the first connecting portion and the second connecting portion. In this way, the distance between the first shaft and the light exit hole of the driving motor is relatively close, which is conducive to improving the anti-shake accuracy.

[0012] In one possible implementation, the second bracket includes a first portion and a second portion that are relatively arranged, the first portion being located between the first connecting portion and the base, and the second portion being located between the second connecting portion and the base; the drive motor also includes a second group of supports, the second group of supports including a plurality of second supports, the first portion being rotatably connected to the base via some of the second supports, and the second portion being rotatably connected to the base via another portion of the second supports, with the center point of the second group of supports being located on the mounting side. Thus, when the first optical element is mounted on the drive motor, the center point of the second group of supports is located on the mounting side, and the center point of the second group of supports is relatively close to the center of gravity of the first optical element, the first bracket, and the second bracket as a whole. Thus, on the one hand, the anti-interference ability of the drive motor can be effectively enhanced when rotating around the second axis for anti-shake; on the other hand, the power consumption of the drive motor can be reduced, which is beneficial for extending the battery life of the electronic device and improving the user experience.

[0013] In one possible implementation, the first portion semi-encloses the first connecting portion, and the second portion semi-encloses the second connecting portion. In this way, the first connecting portion and the second connecting portion can respectively utilize the dimensional space of the first portion in the second direction and the dimensional space of the second portion in the second direction, making the overall structure of the drive motor more compact and facilitating miniaturization of the drive motor.

[0014] In one possible implementation, the first portion includes a first end, a middle portion, and a second end. The middle portion is fixedly connected between the first and second ends, and the second end is located on a side of the first end away from the light inlet. The middle portion protrudes relative to the first and second ends along a side facing away from the light outlet. The first, middle, and second ends collectively enclose a first space. The first connecting portion is mounted in the first space, and a portion of the first support member is connected between the first connecting portion and the middle portion. In this way, the first connecting portion can utilize the first space enclosed by the first, middle, and second ends, making the structure between the first connecting portion and the first portion more compact and facilitating a miniaturized drive motor.

[0015] In one possible implementation, the drive motor may further include a first upper elastic member and a first lower elastic member, wherein the first upper elastic member is connected between the first end portion and the first connecting portion, and the first lower elastic member is connected between the second end portion and the first connecting portion. The elastic force generated by the first upper elastic member and the first lower elastic member causes a portion of the first support member to maintain contact with the wall surface of the first space. In this way, the first upper elastic member and the first lower elastic member can generate preload on the first connecting member, allowing the portion of the first support member between the first connecting portion and the first portion to maintain contact with the first portion and the first connecting portion, thereby facilitating the stability of the movement of the first optical element when the drive motor drives the first optical element to rotate about the first axis.

[0016] In one possible implementation, the drive motor further includes a first magnetic member, a second magnetic member, and a magnetic sheet. The first magnetic member and the second magnetic member are both fixed to the first connecting portion. The first magnetic member is located on the side of the second magnetic member close to the light inlet. The first connecting portion is provided with a first sliding groove. The first sliding groove is used to install a portion of the first support member. The first sliding groove is located between the first magnetic member and the second magnetic member. The magnetic sheet is fixed to the first portion. The magnetic sheet is arranged opposite to the first magnetic member and opposite to the second magnetic member. The magnetic attraction forces generated by the first magnetic member and the second magnetic member, respectively, together with the magnetic sheet, keep the portion of the first support member in contact with the first portion and the first connecting portion. In this way, the first magnetic member can cooperate with the second magnetic member to generate a magnetic attraction force along the second direction on the magnetic sheet in the first portion, thereby enabling the portion of the first support member to maintain contact with the first portion and the first connecting portion, which is beneficial to ensuring the motion stability when the drive motor drives the first optical element to rotate around the first axis.

[0017] In one possible implementation, some of the second support members are connected between the first end of the first portion and the base, and some of the second support members are connected between the second end of the first portion and the base. This allows the first portion to be movably connected to the base via some of the second support members at both the first and second ends, thereby reducing frictional forces between the first portion and the base. Furthermore, the projection of the second set of support members in the second direction substantially does not overlap with the projection of the first set of support members, thereby improving space utilization within the drive motor and facilitating a compact design of the drive motor.

[0018] In one possible implementation, the multiple first support members include multiple first balls and multiple second balls. The first connecting portion is rotatably connected to the first portion via the multiple first balls, and the second connecting portion is rotatably connected to the second portion via the multiple second balls. The center of the circle containing the multiple centers of the multiple first balls is the first rotation center, and the center of the circle containing the multiple centers of the multiple second balls is the second rotation center. The line connecting the first and second rotation centers coincides with the first axis. In this way, the first bracket is rotatably connected to the second bracket via the multiple first and second balls, which helps reduce the motion friction between the first and second brackets.

[0019] In one possible implementation, the plurality of first support members include a first ball and a second ball. The first connecting portion is rotatably connected to the first portion via the first ball, and the second connecting portion is rotatably connected to the second portion via the second ball. The line connecting the center of the first ball and the center of the second ball coincides with the first axis. Alternatively, the contact point between the first ball and the first connecting portion is a first contact point, and the contact point between the second ball and the second connecting portion is a second contact point. The line connecting the first and second contact points coincides with the first axis. Alternatively, the contact point between the first ball and the first portion is a first contact point, and the contact point between the second ball and the second portion is a second contact point. The line connecting the first and second contact points coincides with the first axis. In this way, the first bracket is rotatably connected to the second bracket via the first and second balls, which helps reduce the motion friction between the first and second brackets.

[0020] In one possible implementation, the first connecting portion is provided with a first sliding groove, the first part is provided with a first guide groove, the opening of the first sliding groove is arranged opposite to the opening of the first guide groove, the first sliding groove and the first guide groove constitute a first ball groove, and at least part of the first ball is located in the first ball groove; the second connecting portion is provided with a second sliding groove, the second part is provided with a second guide groove, the opening of the second sliding groove is arranged opposite to the opening of the second guide groove, the second sliding groove and the second guide groove constitute a second ball groove, and at least part of the second ball is located in the second ball groove; at least one of the first sliding groove and the second sliding groove is a V-shaped groove, and one of the first guide groove and the second guide groove is a V-shaped groove; or, at least one of the first guide groove and the second guide groove is a V-shaped groove, and one of the first sliding groove and the second sliding groove is a V-shaped groove.

[0021] It can be understood that the first bracket and the second bracket are respectively provided with two groups of paired opposing grooves (i.e., the first sliding groove and the first guide groove and the second sliding groove and the second guide groove). By setting at least one of the first sliding groove and the second sliding groove to be a V-shaped groove, and 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 bracket from getting stuck when moving relative to the second bracket, and can also automatically correct the relative position between the actual first axis and the theoretical first axis, which is beneficial to improve the smoothness of the movement of the first bracket when rotating around the first axis relative to the second bracket.

[0022] In one possible implementation, the plurality of second support members include at least three third balls, and the second bracket is rotatably connected to the base via the plurality of third balls. The centers of the plurality of third balls are located in the same plane, and the second axis is perpendicular to the plane containing the centers of the plurality of third balls. This helps improve the anti-shake accuracy of the drive motor.

[0023] In one possible implementation, the second bracket is provided with a third guide groove, a fourth guide groove and a fifth guide groove, and the base is provided with a first slide groove, a second slide groove and a third slide groove, and the openings of the third guide groove, the openings of the fourth guide groove and the fifth guide groove are arranged one-to-one with the openings of the first slide groove, the openings of the second slide groove and the openings of the third slide groove, respectively corresponding to the openings of the first slide groove, the second slide groove and the third slide groove to form a third ball groove, a fourth ball groove and a fifth ball groove with the first slide groove, the second slide groove and the third slide groove, respectively, and a plurality of third balls are located in the third ball groove, the fourth ball groove and the fifth ball groove one-to-one; at least two of the third guide groove, the fourth guide groove and the fifth guide groove are V-shaped grooves, and two of the first slide groove, the second slide groove and the third slide groove are V-shaped grooves; or, at least two of the first slide groove, the second slide groove and the third slide groove are V-shaped grooves, and two of the third guide groove, the fourth guide groove and the fifth guide groove are V-shaped grooves.

[0024] It can be understood that at least three groups of paired grooves are respectively arranged on the second bracket and the base (i.e., the third guide groove and the first slide groove, the fourth guide groove and the second slide groove, and the fifth guide groove and the third slide groove), and at least two of the third guide groove, the fourth guide groove and the fifth guide groove are set as V-shaped grooves, and two of the first slide groove, the second slide groove and the third slide groove are V-shaped grooves; or, at least two of the first slide groove, the second slide groove and the third slide groove are V-shaped grooves, and two of the third guide groove, the fourth guide groove and the fifth guide groove are V-shaped grooves, so that the driving motor can determine the position of the second axis while avoiding the second bracket from getting stuck when moving relative to the base, and can also automatically correct the relative position between the actual second axis and the theoretical second axis, which is beneficial to improve the smoothness of the movement of the second bracket when it rotates around the second axis relative to the base.

[0025] In one possible implementation, the drive motor further includes a first drive coil, a second drive coil, a first set of magnetic members, and a second set of magnetic members. The first drive coil and the second drive coil are both fixed to the base. The first set of magnetic members is fixed to the first bracket and is located on the side of the first bracket facing away from the light exit hole. The first set of magnetic members is arranged opposite to the first drive coil. The second set of magnetic members includes a first sub-magnetic member and a second sub-magnetic member. The first sub-magnetic member and the second sub-magnetic member are both fixed to the first bracket. The arrangement direction of the first sub-magnetic member, the mounting bevel, and the second sub-magnetic member is parallel to the first axis. The second drive coil includes a first sub-coil and a second sub-coil. The first sub-coil is arranged opposite to the first sub-magnetic member, and the second sub-coil is arranged opposite to the second sub-magnetic member. In this way, the first and second sets of magnetic members are both fixed to the first bracket, which is conducive to achieving integrated transmission of the drive motor and improving the smoothness of the drive motor's operation when anti-shake is performed. At the same time, multiple sets of coils and magnetic members can be located in different directions of the first bracket, which is conducive to improving the space utilization inside the drive motor and making the drive motor structure more compact.

[0026] In one possible implementation, the drive motor further includes a first drive coil, a second drive coil, a first group of magnetic parts, and a second group of magnetic parts. The first drive coil and the second drive coil are both fixed to the base. The first group of magnetic parts is fixed to the first bracket and is located on the side of the support portion facing away from the light exit hole. The first group of magnetic parts is arranged opposite to the first drive coil. The second group of magnetic parts includes a first sub-magnetic part and a second sub-magnetic part. The first sub-magnetic part and the second sub-magnetic part are both fixed to the second bracket. The arrangement direction of the first sub-magnetic part, the mounting bevel, and the second sub-magnetic part is parallel to the first axis. The second drive coil includes a first sub-coil and a second sub-coil. The first sub-coil is arranged opposite to the first sub-magnetic part, and the second sub-coil is arranged opposite to the second sub-magnetic part. In this way, the first group of magnetic parts and the second group of magnetic parts are respectively fixed to the first bracket and the second bracket, so that the driving force generated by the cooperation of the second group of magnetic parts and the second drive coil can directly act on the second bracket without being disturbed by errors such as assembly between the first bracket and the second bracket, which is beneficial to improving the anti-shake accuracy of the drive motor.

[0027] In one possible implementation, the first drive coil and the first set of magnetic components form a first drive mechanism, while the second drive coil and the second set of magnetic components form a second drive mechanism. Alternatively, the first drive coil and the first set of magnetic components form the second drive mechanism, while the second drive coil and the second set of magnetic components form the first drive mechanism. In this way, the coils and magnetic components work together to generate a strong driving force, facilitating the motor's ability to support the large mass of the first optical element.

[0028] In one possible implementation, the drive motor further includes a magnetic member secured to the base, with a projection of the magnetic member parallel to the second axis overlapping at least partially with the first set of magnetic members. The first bracket, under the force acting between the magnetic member and the first set of magnetic members, compresses the second bracket. In this way, the magnetic member provides preload pressure on the first and second brackets, allowing the first set of support members to maintain contact with the first and second brackets, while also allowing the second set of support members to maintain contact with the second bracket and the base, thereby facilitating motion stability during anti-shake operation of the drive motor.

[0029] In one possible implementation, the first bracket further includes a support portion, a first sidewall, and a second sidewall. The first sidewall and the second sidewall are opposed to each other and spaced apart. The first and second sidewalls are arranged parallel to the first axis. The support portion is connected between the first and second sidewalls. The support portion, the first sidewall, and the second sidewall enclose an installation space. The surface of the support portion facing the installation space constitutes a mounting slope of the first bracket, and the installation space is used to mount the first optical element. The first connecting portion is located on the side of the first sidewall facing away from the second sidewall and is fixedly connected to the end of the first sidewall facing the light exit aperture. The second connecting portion is located on the side of the second sidewall facing away from the first sidewall and is fixedly connected to the end of the second sidewall near the light exit aperture. In this way, the first bracket can form a semi-enclosed structure, thereby effectively supporting and mounting the first optical element. Furthermore, both the first and second connecting portions can be located near the light exit aperture, so that the first axis is positioned on the mounting side of the mounting slope, thereby improving anti-shake accuracy.

[0030] In one possible implementation, the drive motor further includes a base plate, which includes a connected main portion and an extension portion, wherein the main portion is fixedly connected to the surface of the base facing away from the light inlet, and the extension portion is disposed opposite the first side wall, with the arrangement direction of the extension portion and the first side wall being parallel to the second axis; the extension portion is provided with a first protrusion, the first protrusion facing the first side wall, the first side wall is provided with a first limiting groove, and at least a portion of the first protrusion is located within the first limiting groove. In this way, when the first bracket rotates relative to the base around the second axis under the action of the second bracket, the first protrusion can cooperate with the first limiting groove, thereby effectively preventing the first bracket from rotating too much relative to the base around the second axis, causing the first optical element to collide with the base of the drive motor and be damaged, thereby helping to extend the service life of the camera module.

[0031] In one possible implementation, a collision prevention protrusion is provided on a side of the first bracket facing away from the light exit hole, and a retaining hole is provided on the base, with at least a portion of the collision prevention protrusion located within the retaining hole. Thus, when the first bracket rotates relative to the base about the first axis, the collision prevention protrusion engages with the retaining hole, effectively preventing the first bracket from rotating excessively relative to the base about the first axis, which could result in damage from collision between the first optical element and the base of the drive motor. This helps extend the life of the camera module.

[0032] In one possible implementation, the distance between the first axis and the mounting bevel is greater than 0.01 mm; and / or the distance between the first axis and the mounting bevel is greater than or equal to 5 mm. This allows the first axis to be located on the mounting side and at a certain distance from the mounting bevel, which helps reduce focus offset and thus effectively minimizes the impact of focus offset on the modulation transfer function, thereby improving the stabilization accuracy of the entire camera module and enhancing image quality.

[0033] In one possible implementation, the first bracket and the light inlet are arranged in a first direction, and the first bracket and the light outlet are arranged in a second direction. A first connecting portion and a second connecting portion are provided on a side of the first bracket near the light outlet. The first connecting portion and the second connecting portion are opposite and spaced apart, and the arrangement direction of the first connecting portion and the second connecting portion is parallel to the first axis. The drive motor also includes a first set of support members, the first set of support members including a plurality of first support members. The first connecting portion is rotatably connected to the base via some of the first support members, and the second connecting portion is rotatably connected to the base via another portion of the first support members. In this way, the first bracket is directly and movably connected to the base, which helps reduce errors caused by assembly and other factors between the first bracket and the base, and improves movement accuracy.

[0034] In a second aspect, an anti-shake assembly is provided. The anti-shake assembly includes a first optical element and the aforementioned drive motor, the first optical element including an optical path folding element, the optical path folding element including a first surface, a second surface, and a third surface, the first surface being perpendicular to the third surface, the second surface being disposed toward the first surface and the third surface and connecting the first surface and the second surface, the first surface and the third surface being both transmissive surfaces, the second surface being a reflective surface, the first surface being disposed opposite the light inlet, and the third surface being disposed opposite the light outlet; the first optical element having a light inlet axis and a light outlet axis, the light inlet axis being parallel to the first direction, and the light outlet axis being parallel to the second direction.

[0035] It is understood that the first axis of the drive motor of the anti-shake assembly in this embodiment is located on the side of the mounting bevel closest to the light exit hole, i.e., on the mounting side of the mounting bevel. The first axis is perpendicular to the plane containing the first and second directions. This allows the drive motor to rotate the first optical element about the first axis, minimizing the focus shift. This effectively reduces the impact of focus shift on the modulation transfer function, improving the anti-shake accuracy of the entire camera module and enhancing image quality.

[0036] In a third aspect, an anti-shake assembly is provided. The anti-shake assembly includes a first optical element and the aforementioned drive motor. The first optical element includes an optical path folding element. The optical path folding element includes a reflective surface and a mounting surface. The reflective surface and the mounting surface are disposed opposite each other. The mounting surface faces the mounting inclined surface of the first bracket and is fixedly connected to the mounting inclined surface. The reflective surface is disposed opposite the mounting inclined surface. The first optical element has an optical input axis and an optical output axis. The optical input axis is parallel to the first direction, and the optical output axis is parallel to the second direction.

[0037] It is understood that the first axis of the drive motor of the anti-shake assembly in this embodiment is located on the side of the mounting bevel closest to the light exit hole, i.e., on the mounting side of the mounting bevel. The first axis is perpendicular to the plane containing the first and second directions. This allows the drive motor to rotate the first optical element about the first axis, minimizing the focus shift. This effectively reduces the impact of focus shift on the modulation transfer function, improving the anti-shake accuracy of the entire camera module and enhancing image quality.

[0038] Secondly, compared to the anti-shake component in which the optical path folding element is a reflective prism, the first surface, the second surface and the third surface of the reflective prism are all solid surfaces, and the transmission of light between the first surface and the third surface is all inside the reflective prism. The refractive index inside the reflective prism is relatively high, which increases the optical path requirement of the entire camera module, the focusing path of the focusing component is longer, and the overall size of the module is longer. The optical path folding element in this 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 and the light outlet is all in the air. The refractive index in the air is relatively low, which is conducive to reducing the optical path requirement of the camera module, thereby shortening the focusing path of the focusing component, and helping to reduce the overall size of the module in the second direction, thereby realizing a miniaturized setting of the camera module.

[0039] In one possible implementation, the drive motor further includes an optical mount, at least a portion of which is fixedly connected between the optical path folding element and the mounting bevel, and the strength of the optical mount is greater than the strength of the portion of the first bracket where the mounting bevel is located.

[0040] It is understandable that, compared to direct contact between the optical path folding element and the mounting bevel of the first bracket, the strength of the portion of the first bracket where the mounting bevel is located is lower, making the portion where the mounting bevel is located susceptible to deformation due to impact or in a high-temperature environment, thereby affecting the surface accuracy of the contact surface between the optical path folding element and the mounting bevel, and reducing the optical quality. In this embodiment, the optical path folding element is indirectly fixed to the mounting bevel via an optical mounting member. The optical path folding element does not directly contact the mounting bevel, and the optical mounting member is relatively strong, making the optical mounting member less susceptible to deformation due to impact or in a high-temperature environment. This is beneficial for ensuring the surface accuracy of the contact surface between the optical path folding element and the optical mounting member, and thus ensuring the optical quality of the optical path folding element.

[0041] In one possible implementation, the optical mounting member includes a first mounting member and a second mounting member, the first mounting member and the second mounting member are arranged at intervals, at least a portion of the first mounting member is fixedly connected between the optical path folding element and the mounting bevel, and at least a portion of the second mounting member is fixedly connected between the optical path folding element and the mounting bevel.

[0042] It can be understood that compared to the optical mounting part which is a whole, that is, the first mounting part and the second mounting part are formed in one piece. When the driving motor is hit, the stress of the optical mounting part is more concentrated and will be transmitted inward to the first optical element, causing the first optical element to be pulled, affecting the surface accuracy of the first optical element and reducing the optical quality. In this embodiment, the optical mounting part is provided as two independent and separately provided first mounting parts and the second mounting part. In this way, when the driving motor is hit, the first mounting part and the second mounting part can respectively withstand stress in different directions, thereby preventing the first optical element from being pulled by stress in different directions, thereby reducing its own surface accuracy and affecting the optical quality.

[0043] In one possible implementation, the first optical element further includes a first lens, located on the light-entering side of the optical path folding element, and having positive optical power. This allows the first lens to achieve a light-gathering effect, allowing as much external light as possible to enter the optical path folding element, thereby increasing the amount of light entering the entire first optical element, which in turn facilitates increasing the amount of light entering the subsequent focusing assembly.

[0044] In one possible implementation, the first optical element further includes a second lens located on the light-exiting side of the optical path folding element, and having negative optical power. This second lens thus has a diffraction effect, diffusing as much light as possible from the optical path folding element, thereby increasing the amount of light emitted by the entire first optical element and, in turn, increasing the amount of light entering the subsequent focusing assembly.

[0045] In one possible implementation, the projection point of the first axis on the plane containing the first direction and the second direction is the first point, and the distance between the first point and the light-emitting axis is less than or equal to 3 mm. This closer distance between the first point and the light-emitting axis helps improve the anti-shake accuracy of the anti-shake assembly.

[0046] In one possible implementation, the drive motor further includes a second bracket and a second drive mechanism. The second bracket is movably connected between the base and the first bracket. The second drive mechanism is configured to drive the second bracket and the first bracket to rotate relative to the base about a second axis. The second axis intersects the first axis, passes through the light exit hole and the mounting bevel, and is parallel to the second direction. The second axis is spaced less than or equal to 3 mm from the light exit axis. This closer distance between the second axis and the light exit axis facilitates improved anti-shake accuracy of the anti-shake assembly.

[0047] In one possible implementation, the drive motor further includes a second set of support members, through which the second bracket is slidably connected to the base; the distance between the center point of the second set of support members and the center of gravity of the first bracket, the second bracket, and the first optical element as a whole is less than or equal to 0.3 mm. This closer distance between the center point of the second set of support members and the center of gravity of the first bracket, the second bracket, and the first optical element as a whole effectively enhances the drive motor's anti-interference capability when rotating about the second axis for anti-shake performance; it also reduces the drive motor's power consumption, thereby extending the battery life of the electronic device and improving the user experience.

[0048] In a fourth aspect, a camera module is provided. The camera module includes a focusing assembly, an image sensor and the above-mentioned anti-shake assembly, 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 of this embodiment is located on the side of the mounting bevel close to the light-emitting hole, that is, the mounting side of the mounting bevel. The first axis is perpendicular to the plane where 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 axis, the focus offset is small, thereby effectively reducing the influence of the focus offset on the modulation transfer function, which is beneficial to improving the anti-shake accuracy of the entire camera module and improving the imaging quality.

[0049] In a fifth aspect, an electronic device is provided. The electronic device includes a device housing and the aforementioned camera module, wherein the camera module is disposed in the device housing. The camera module of the electronic device in this embodiment has high anti-shake accuracy and high imaging quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0115] The embodiments of the present application are described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0116] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship remains unchanged after the connection. "Rotational connection" means that the two are connected to each other and can rotate relative to each other after the connection. "Sliding connection" means that the two are connected to each other and can slide relative to each other after the connection. The directional terms mentioned in the embodiments of the present application, such as "up", "down", "left", "right", "inside", "outside", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" means at least two.

[0117] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0118] In the embodiments of this application, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0119] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in some other embodiments," and "in another embodiment" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0120] It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0121] Fig. 1 is a schematic diagram of the structure of an electronic device 1000 according to an embodiment of the present application. Fig. 2 is a schematic diagram of the cross-sectional structure of the electronic device 1000 shown in Fig. 1 taken along line AA.

[0122] As shown in Figures 1 and 2, 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, an in-vehicle device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet. The electronic device 1000 of the embodiment shown in Figure 1 is described using a mobile phone as an example.

[0123] As shown in Figure 1, the electronic device 1000 may include a camera module 100, a device housing 200, and a screen 300. The camera module 100 may be a rear camera module or a front camera module. It should be noted that Figure 1 and the related figures below only schematically illustrate some components included in the electronic device 1000, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1 and the figures below. In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may also not include the screen 300.

[0124] For ease 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 defined as the Y-axis. The thickness direction of the electronic device 1000 is defined as the Z-axis. It is understood that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs.

[0125] In this embodiment, the device housing 200 may include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. For example, the back cover 202 may be fixed to the frame 201 by adhesive. The back cover 202 may also be integrally formed with the frame 201, i.e., the back cover 202 and the frame 201 form a single unitary structure.

[0126] Alternatively, the screen 300 can be located on the side of the frame 201 away from the back cover 202. In this case, the screen and back cover 202 are located on either side of the frame 201. The screen 300, frame 201, and back cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, receiver, or microphone. The screen 300 can be either flat or curved.

[0127] 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 back cover 202. The back cover 202 can be provided with a light-transmitting hole 203. The shape of the light-transmitting hole 203 is not limited to the circular shape shown in FIG. 1 . The light-transmitting hole 203 connects the interior of the electronic device 1000 to the exterior of the electronic device 1000. Light outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting hole 203. The camera module 100 can collect ambient light entering the interior of the electronic device 1000.

[0128] Fig. 3 is a schematic diagram of the structure of the anti-shake component of the camera module 100 shown in Fig. 2 in some embodiments. Fig. 4 is a schematic diagram of the exploded structure of the anti-shake component shown in Fig. 3 in some embodiments.

[0129] As shown in Figures 2 to 4, the camera module 100 may include an anti-shake component 1, a focus 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 through the anti-shake component 1 and the focus component 2 in sequence, and finally be imaged by the image sensor 3. For example, the anti-shake component 1, the focus component 2, and the image sensor 3 can be arranged in sequence along the X-axis.

[0130] In some embodiments, one or more reflective lenses / prisms may be additionally disposed between the focusing assembly 2 and the image sensor 3 to alter the light propagation path between the focusing assembly 2 and the image sensor 3. This allows the light emitted by the focusing assembly 2 to undergo one or more reflections before finally entering the image sensor 3. This lengthens the overall light path of the camera module 100, thereby increasing the zoom factor of the camera module 100.

[0131] For example, the anti-shake assembly 1 may include a drive motor 1a and a first optical element 1b. The first optical element 1b may be mounted on the drive motor 1a. The drive motor 1a may drive the first optical element 1b to rotate about a first axis (not shown) and / or a second axis (not shown), thereby achieving optical image stabilization (OIS) for the camera module 100 and improving the imaging quality of the camera module 100.

[0132] For example, the focusing assembly 2 may include a focusing motor (not shown) and a second optical element (not shown). The second optical element may be mounted on the focusing motor. The focusing motor may control the second optical element to move along the optical axis to achieve auto focus (AF). The second optical element may include at least one lens. The first optical element and the second optical element may together constitute the optical system of the camera module 100.

[0133] Figure 5 is a schematic diagram of the exploded structure of the first optical element 1b of the anti-shake assembly 1 shown in Figure 3 in some embodiments. Figure 6 is a schematic diagram of a partial cross-sectional structure of an embodiment of the anti-shake assembly 1 shown in Figure 3 taken along B1-B1.

[0134] As shown in Figures 5 and 6, the first optical element 1b may include an incident surface 101, a reflective surface 102, and an exit surface 103. Light may enter the interior of the first optical element 1b from the incident surface 101 of the first optical element 1b, and after being reflected by the reflective surface 102, be emitted from the exit surface 103. The light-entry axis T1 of the first optical element 1b may be perpendicular to the incident surface 101. The light-exiting axis T2 of the first optical element 1b may be perpendicular to the exit surface 103. In this embodiment, the light-entry axis T1 of the first optical element 1b may be parallel to the Z-axis direction, and the light-exiting axis T2 may be parallel to the X-axis direction. Among them, the first optical element 1b may include an optical path folding element 104 and a first lens 105. The first lens 105 may be fixed on the light-entry side of the optical path folding element 104. At this time, the incident surface of the first lens 105 may constitute the incident surface 101 of the first optical element 1b.

[0135] Exemplarily, the optical path folding element 104 may be a reflective prism. The cross-section of the optical path folding element 104 may be triangular. Specifically, the optical path folding element 104 may include a first surface 1041, a second surface 1042, and a third surface 1043. The first surface 1041 and the third surface 1043 may be perpendicular to each other. The second surface 1042 may be connected between the first surface 1041 and the third surface 1043. The first surface 1041 may be perpendicular to the light input axis. The third surface 1043 may be perpendicular to the light output axis. Both the first surface 1041 and the third surface 1043 may be transmissive surfaces. The second surface 1042 may be a reflective surface. In this way, light may enter the interior of the optical path folding element 104 from the first surface 1041, and after being reflected by the second surface 1042, be emitted from the third surface 1043. At this time, the second surface 1042 of the optical path folding element 104 may constitute the reflective surface 102 of the first optical element 1b. The third surface 1043 of the optical path folding element 104 may constitute the exit surface 103 of the first optical element 1 b .

[0136] For example, the cross-section of the optical path folding element 104 can be an isosceles triangle, that is, the angle between the second surface 1042 and the first surface 1041 can be 45°, and the angle between the second surface 1042 and the third surface 1043 can also be 45°. In this case, after the light is reflected by the second surface 1042, the deflection angle of the light can be 90° (as shown in Figure 6). In other embodiments, the angle between the second surface 1042 and the first surface 1041 can also be other angles, which is not specifically limited in this application.

[0137] 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 bonding or other means. The first lens 105 can be a lens with positive optical power. In this way, the first lens 105 can have a focusing effect, allowing as much external light as possible to enter the optical path folding element 104, thereby increasing the amount of light entering the entire first optical element 1b, which is beneficial for increasing the amount of light entering the subsequent focusing assembly 2.

[0138] 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 bonding or the like. In this way, the second lens 106 has a light-astigmatism effect, and the second lens 106 may diverge as much light as possible emitted from the optical path folding element 104, thereby increasing the light output of the entire first optical element 1b, which is beneficial to increasing the light input 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.

[0139] Figure 7a is a simplified schematic diagram of the first optical element 1b shown in Figure 6. Figure 7b is a schematic diagram of the structure shown in Figure 7a from another perspective. It should be noted that the first optical element 1b in Figure 7a only illustrates the optical path folding element 104 and the first lens 105, and the optical path folding element 104 only illustrates the second surface 1042 (i.e., the reflective surface 102 of the first optical element 1b).

[0140] As shown in Figures 7a and 7b, the first optical element 1b can rotate around the first axis R1 (i.e., nodding motion). The plane where the light input axis T1 and the light output axis T2 are located is the reference plane M0. The first axis R1 can be perpendicular to the light input axis T1 and also perpendicular to the light output axis T2, that is, the first axis R1 can be perpendicular to the reference plane M0. The intersection of the light output axis T2 and the reflective surface 102 is the first intersection G1. The straight line L0 intersects with the edge line of the first lens 105 close to the focusing assembly 2 and is parallel to the light input axis T1. The straight line L0 intersects with the light output axis T2 at the second intersection G2. For example, the straight line L0 can coincide with the exit surface 103, that is, the intersection of the light output axis T2 and the exit surface 103 is the second intersection G2. The intersection of the light input 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 point, 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 perpendicularity between the first axis R1 and the light input axis T1 can be completely perpendicular or approximately perpendicular, for example, with a deviation within 1°. The perpendicularity between the first axis R1 and the light output axis T2 also applies to the above definition and will not be repeated here.

[0141] For example, the projection point of the first axis R1 on the reference plane M0 is the first point. The first point can be located within the area defined by line L1, line L2, and line L3. Line L1 and line L2 are both parallel to the light-exiting axis T2. Line L1 is located on the side of the light-exiting axis T2 that is closer to the first lens 105. Line L2 is located on the side of the light-exiting axis T2 that is away from the first lens 105. Line L1 intersects the reflective surface 102 at point k1. Line L2 intersects the reflective surface at point k2. The distances from line k1 and line k2 to the light-exiting axis T2 are both 3 mm. Line L3 is parallel to the light-input axis T1. The distance between line L3 and the light-input axis T1 is 20 mm.

[0142] It should be noted that the area defined by straight lines L1, L2, and L3 includes the area enclosed by straight lines L1, L2, and L3 and the boundaries of straight lines L1, L2, and L3. In other words, the first point can be located on the image side of the reflective surface 102, and the distance between the first point and the light-emitting axis T2 can be less than or equal to 3 mm. The distance between the first point and the second intersection G2 in the X-axis direction can be less than or equal to 20 mm. In this embodiment, the first axis R1 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.

[0143] Figure 7c is a simplified schematic diagram of the first optical element 1b of the anti-shake assembly 1 rotating about the first axis R1 for anti-shake in some embodiments. Figure 7d is a simplified schematic diagram of the first optical element 1b shown in Figure 7a rotating about the first axis R1 for anti-shake. It should be noted that the left-hand illustrations in Figures 7c and 7d are both schematic diagrams of the first optical element 1b experiencing vibration and without anti-shake enabled, while the right-hand illustrations are both schematic diagrams of the first optical element 1b experiencing vibration and with anti-shake enabled.

[0144] As shown in Figures 7a, 7c, and 7d, when the electronic device 1000 shakes in a direction parallel to the reference plane M0 and the drive motor 1a does not turn on the anti-shake function, the focus of the first optical element 1b is the first original focus P0. It should be understood that the light emitted by the first optical element 1b will produce multiple focuses, that is, the drive motor 1a has multiple first original focuses P0 when the anti-shake function is not turned on, and only one of the first original focuses P0 is shown here. When the electronic device 1000 shakes in a direction parallel to the reference plane M0 and the drive motor 1a turns on the anti-shake function, the drive 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.

[0145] It is understood that in some embodiments, the first axis R1′ is located on the reflective surface 102 of the first optical element 1b, or on the side of the reflective surface 102 facing away from the exit surface 103. However, after the first optical element 1b rotates about the first axis R1′ for anti-shake, the first focus P1′ generated by the first optical element 1b is significantly offset from the first original focus P0, causing a significant decrease in the modulation transfer function (MTF) of the camera module 100 as a whole, thereby affecting image quality.

[0146] In this embodiment, the first axis R1 can be located on the side of the reflective surface 102 facing the exit surface 103, that is, on the image side of the reflective surface 102 (that is, on the right side of the reflective surface 102 in FIG. 7 a ). In this way, the first axis R1 is located on the side of the reflective surface 102 of the first optical element 1b facing the exit surface 103. As a result, after the first optical element 1b rotates about the first axis R1 for anti-shake, the first focus P1 generated by the first optical element 1b is less offset from the first original focus P0. This helps improve the anti-shake accuracy of the camera module 100 and reduces the impact of focus offset on the modulation transfer function, thereby improving imaging quality.

[0147] In addition, in this embodiment, the first axis R1 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 focus shift caused by the rotation of the first optical element 1b about the first axis R1 is smaller, which helps to further reduce the impact of the focus shift on the modulation transfer function, thereby further improving imaging quality.

[0148] Figure 8 is a simplified schematic diagram of the first optical element 1b shown in Figure 7a. Figure 9a is a simplified schematic diagram of the first optical element 1b of the anti-shake assembly 1 in some embodiments rotating around the second axis R2 for anti-shake. Figure 9b is a simplified schematic diagram of the first optical element 1b shown in Figure 8 rotating around the second axis R2 for anti-shake. It should be noted that the first optical element 1b in Figure 8 only illustrates the optical path folding element 104 and the first lens 105, and the optical path folding element 104 only illustrates the second surface 1042 (that is, the reflective surface 102 of the first optical element 1b). The illustrations on the left side of Figures 9a and 9b are both schematic diagrams of the first optical element 1b shaking and the anti-shake is not turned on, and the illustrations on the right side are both schematic diagrams of the first optical element 1b shaking and the anti-shake is turned on.

[0149] As shown in Figures 8 to 9b, the first optical element 1b can rotate around the second axis R2 (i.e., a shaking motion). The second axis R2 can be parallel to the light-emitting 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-emitting axis T2 can be less than or equal to 3 mm, that is, the second axis R2 can be located in a cylindrical space with a radius of 3 mm and the light-emitting axis T2 as the center axis. For example, the second axis R2 can coincide with the light-emitting axis T2. It should be understood that the second axis R2 can be completely parallel to the light-emitting axis T2 or approximately parallel, for example, with a deviation within 1°. When the electronic device 1000 shakes in a direction parallel to the reference plane M0 and the first optical element 1b is not anti-shake, the exit surface M1 of the anti-shake component 1 can be parallel to the incident surface M2 of the focusing component 2. The exit surface M1 of the anti-shake component 1 is parallel to the exit surface 103 of the first optical element 1b. When the driving motor 1a turns on the anti-shake function, 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, thereby achieving anti-shake.

[0150] It is understood that in some embodiments, the second axis R2' coincides with the light-entry axis G1 of the first optical element 1b, that is, the second axis R2' can be parallel to the Z-axis. However, when the first optical element 1b rotates about the second axis R2', the exit surface M1' of the anti-shake assembly 1 forms an angle with the incident surface M2 of the focusing assembly 2, resulting in a large inclination angle between the first optical element 1b and the focusing assembly 2. This significantly degrades the optical quality of the camera module 100, resulting in lower imaging quality. Furthermore, the focus offset is large, causing a significant decrease in the overall modulation transfer function of the camera module 100, affecting imaging quality.

[0151] In this embodiment, the second axis R2 can be parallel to the light-emitting axis T2, that is, the second axis R2 can be perpendicular to the exit surface 103 of the first optical element 1b and the incident surface M2 of the focusing assembly 2. In this way, when the first optical element 1b rotates about the second axis R2, the exit surface M1 of the anti-shake assembly 1 can always remain parallel to the light-emitting axis T2 and perpendicular to the incident surface M2 of the focusing assembly 2. This can effectively reduce the inclination angle between the first optical element 1b and the focusing assembly 2, improve the anti-shake accuracy of the camera module 100, minimize the degradation in the optical quality of the camera module 100, and minimize the focus offset, which helps reduce the impact of focus offset on the modulation transfer function, thereby improving the imaging quality of the camera module 100.

[0152] In addition, the distance between the second axis R2 and the light-emitting axis T2 can be less than or equal to 3 mm, so that the second axis R2 can be set close to the light-emitting axis T2, thereby better reducing the impact of focus offset on the modulation transfer function, which is beneficial to improving the imaging quality of the camera module 100.

[0153] Referring to Figures 2, 7a, and 8, it can be understood that compared to camera modules that implement optical image stabilization by additionally placing a reflective prism between the focus assembly and the image sensor and controlling the displacement of the image sensor, the module is larger. The camera module 100 in this embodiment achieves optical image stabilization for the entire camera module 100 by providing a drive motor 1a to drive the first optical element 1b to rotate about the first axis R1 and / or to drive the first optical element 1b to rotate about the second axis R2. This eliminates the need for an additional prism between the focus assembly 2 and the image sensor 3, resulting in a smaller module size and facilitating a miniaturized camera module 100.

[0154] Secondly, the first axis R1 in this embodiment is perpendicular to both the light input axis T1 and the light output axis T2 (that is, parallel to the Y-axis direction in this embodiment), and is located on the side of the reflective surface 102 of the first optical element 1b close to the exit surface 103, that is, the image side of the reflective surface 102. The second axis R2 is parallel to the light output axis T2. In this way, whether the first optical element 1b rotates around the first axis R1 or the second axis R2, the focus offset is small. At the same time, the exit surface M1 of the anti-shake component 1 can always remain parallel to the incident surface M2 of the focusing component 2, thereby effectively improving the anti-shake accuracy of the camera module 100, reducing the influence of focus offset and tilt angle on the overall modulation transfer function of the camera module 100, and improving the imaging quality of the camera module 100.

[0155] In other words, the camera module 100 in this embodiment performs anti-shake by controlling the first optical element 1b to rotate around the first axis R1 and / or the second axis R2, and 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 exit surface 103 (that is, the image side of the reflective surface 102), so that the focus offset of the camera module 100 is small when performing optical image stabilization, thereby having higher anti-shake accuracy, and the camera module 100 has better imaging quality.

[0156] The above specifically introduces the structure of the electronic device 1000, the structure of the camera module 100 and the anti-shake principle of the first optical element 1b of the camera module 100. The following will specifically introduce the structure of the driving motor 1a in the camera module 100 with reference to the relevant drawings.

[0157] Fig. 10 is a schematic diagram of the structure of the drive motor 1a of the anti-shake assembly 1 shown in Fig. 3 in some embodiments. Fig. 11 is a schematic diagram of the exploded structure of the drive motor 1a shown in Fig. 10 in some embodiments.

[0158] As shown in Figures 10 and 11, the drive motor 1a may include a base 10, a shell 20, a circuit assembly 30, a magnetic component 40 and a mover 50. Among them, the base 10 and the shell 20 can together constitute the stator of the drive motor 1a. It should be understood that in this embodiment, the width direction of the drive motor 1a, that is, the width direction of the electronic device 1000, is the X-axis direction. The length direction of the drive motor 1a, that is, the length direction of the electronic device 1000, is the Y-axis direction. The thickness direction of the drive motor 1a, that is, the thickness direction of the electronic device 1000, is the Z-axis direction. In other embodiments, the coordinate system setting of the drive motor 1a can be flexibly set according to specific actual needs.

[0159] Fig. 12 is a schematic diagram of the exploded structure of the circuit assembly 30 of the driving motor 1a shown in Fig. 11 in some embodiments. Fig. 13 is a schematic diagram of the structure of the circuit assembly 30 shown in Fig. 12 .

[0160] As shown in Figures 12 and 13, the circuit assembly 30 may include a circuit board 31, a coil 32, a position sensor 33, a first reinforcement plate 34, and a second reinforcement plate 35. The coil 32 and the position sensor 33 may be fixed to the circuit board 31 by welding or other means. The coil 32 and the position sensor 33 may be electrically connected to the circuit board 31. The circuit board 31 may be a flexible circuit board. The position sensor 33 may be a Hall effect sensor. In other embodiments, the circuit board 31 may be a rigid circuit board or a rigid-flexible circuit board. The position sensor 33 may also be another type of sensor.

[0161] Exemplarily, the circuit board 31 may include a main plate 31a and an extension plate 31b. The main plate 31a may include a first sub-plate 311, a second sub-plate 312, and a third sub-plate 313. The first sub-plate 311 and the third sub-plate 313 may be arranged opposite each other and spaced apart. The second sub-plate 312 may be fixedly connected between the first sub-plate 311 and the third sub-plate 313. In this case, the first sub-plate 311, the second sub-plate 312, and the third sub-plate 313 may generally form a "concave"-shaped structure. The extension plate 31b may be fixedly connected to the third sub-plate 313 and bend relative to the third sub-plate 313 in a direction toward the first sub-plate 311. It should be understood that, for the convenience of describing the specific structure and shape of the circuit board 31, this embodiment describes the circuit board 31 as being divided into four parts. However, this does not affect the circuit board 31 being an integrally formed structure, i.e., the first sub-plate 311, the second sub-plate 312, the third sub-plate 313, and the extension plate 31b may be integrally formed. In other embodiments, the first sub-board 311 , the second sub-board 312 , the third sub-board 313 and the extension board 31 b may all be independent rigid circuit boards 31 , and may be electrically connected to each other via conductive members such as wires.

[0162] For example, the coil 32 may include a first drive coil 321 and a second drive coil 322. The first drive coil 321 may be fixed to the surface of the second sub-board 312 facing the first sub-board 311. The second drive coil 322 may include a first sub-coil 3221 and a second sub-coil 3222. The first sub-coil 3221 may be fixed to the surface of the first sub-board 311 facing the third sub-board 313. The second sub-coil 3222 may be fixed to the surface of the third sub-board 313 facing the first sub-board 311.

[0163] For example, the position sensor 33 may include a first sensor 331, a second sensor 332, and a third sensor 333. The first sensor 331 may be fixed to the second sub-board 312 and located within the coil hole of the first drive coil 321. The second sensor 332 may be fixed to the first sub-board 311 and located within the coil hole of the first sub-coil 3221. The third sensor 333 may be fixed to the third sub-board 313 and located within the coil hole of the second sub-coil 3222.

[0164] Exemplarily, the first reinforcement plate 34 can be fixed to the surface of the second sub-plate 312 facing away from the first drive coil 321. The shape of the first reinforcement plate 34 can be adapted to the shape of the second sub-plate 312. The first reinforcement plate 34 can structurally reinforce the second sub-plate 312. The second reinforcement plate 35 can be fixed to the surface of the extension plate 31b facing away from the first sub-plate 311. The shape of the second reinforcement plate 35 can be adapted to the shape of the extension plate 31b. The second reinforcement plate 35 can structurally reinforce the extension plate 31b. In other embodiments, the circuit assembly 30 may also not include the first reinforcement plate 34 and / or the second reinforcement plate 35.

[0165] FIG14 is a schematic structural diagram of the base 10 of the driving motor 1 a shown in FIG11 from another perspective.

[0166] As shown in Figure 14 , the base 10 can be roughly square-shaped. The base 10 can include a frame portion 10a and a bottom portion 10b. The frame portion 10a can be fixedly connected to the outer edge of the bottom portion 10b and, together with the bottom portion 10b, enclose a housing space 10c. The housing space 10c can be used to accommodate at least a portion of the mover 50, at least a portion of the coil 32, and the first optical element 1b. For ease of understanding, the frame portion 10a and the bottom portion 10b of the base 10 are schematically demarcated by dotted lines in Figure 14 .

[0167] Exemplarily, the frame portion 10a may include a first side portion 11, a second side portion 12 and a third side portion 13. The first side portion 11 may be opposite to and spaced from the third side portion 13. The second side portion 12 may be fixedly connected between the first side portion 11 and the third side portion 13. At this time, the frame portion 10a may be roughly in the shape of a "concave" character. Among them, the first side portion 11 may be provided with a first avoidance hole 111. The second side portion 12 may be provided with a second avoidance hole 121. The third side portion 13 may be provided with a third avoidance hole 131. The first avoidance hole 111, the second avoidance hole 121 and the third avoidance hole 131 may all pass through the inner and outer side walls of the frame portion 10a and connect to the accommodating space 10c of the base 10.

[0168] For example, the first side portion 11 may be provided with a first slide groove 112 and a second slide groove 113. The first slide groove 112 and the second slide groove 113 may be spaced apart along the Z-axis direction. The opening of the first slide groove 112 and the opening of the second slide groove 113 may both be formed on the surface of the first side portion 11 facing away from the second side portion 12. The portion of the first side portion 11 between the first slide groove 112 and the second slide groove 113 may be recessed toward the second side portion 12 to form a first avoidance groove 114. The bottom wall of the first avoidance groove 114 may be generally arc-shaped.

[0169] Exemplarily, the third side portion 13 may be provided with a third slide groove 132 and a fourth slide groove 133. The third slide groove 132 and the fourth slide groove 133 may be spaced apart along the Z-axis direction. The opening of the third slide groove 132 and the opening of the fourth slide groove 133 may both form a surface of the third side portion 13 facing away from the second side portion 12. The portion of the third side portion 13 located between the third slide groove 132 and the fourth slide groove 133 may be recessed in a direction approaching the second side portion 12 to form a second avoidance groove 134. The bottom wall of the second avoidance groove 134 may be generally arc-shaped. The shape of the second avoidance groove 134 may be the same as that of the first avoidance groove 114.

[0170] Exemplarily, at least two of the first sliding groove 112 , the second sliding groove 113 , the third sliding groove 132 and the fourth sliding groove 133 may be “V”-shaped grooves.

[0171] Figure 15 is a schematic diagram of a partial cross-section of the drive motor 1a shown in Figure 10, taken along line CC. Figure 16 is a schematic diagram of the assembled structure of the base 10, circuit assembly 30, and magnetic element 40 of the drive motor 1a shown in Figure 11, viewed from another perspective. For ease of understanding, the frame 10a and bottom 10b of the base 10 are schematically demarcated by dotted lines in Figure 15.

[0172] As shown in Figures 14 to 16, the main plate 31a of the circuit board 31 can be arranged around the outer peripheral side of the frame portion 10a and fixedly connected to the frame portion 10a. Among them, the first sub-plate 311, the second sub-plate 312, and the third sub-plate 313 can be fixed to the first side portion 11, the second side portion 12, and the third side portion 13 in sequence. At this time, at least a portion of the first drive coil 321 can be located in the second avoidance hole 121. At least a portion of the first sub-coil 3221 can be located in the first avoidance hole 111. At least a portion of the second sub-coil 3222 can be located in the third avoidance hole 131. In this way, by fixing the main body plate 31a of the circuit board 31 to the outer peripheral side surface of the frame 10a, and placing the first drive coil 321, the first sub-coil 3221 and the second sub-coil 3222 in the second avoidance hole 121, the first avoidance hole 111 and the third avoidance hole 131 respectively, the width and length dimensions of the frame 10a can be effectively utilized to place the coil 32, thereby improving the space utilization inside the drive motor 1a, which is conducive to the miniaturization of the drive motor 1a.

[0173] For example, the extension plate 31b of the circuit board 31 can be fixed to the surface of the bottom 10b facing away from the accommodating space 10c. A portion of the extension plate 31b can extend relative to the base 10. The magnetic member 40 can be fixedly connected to the surface of the first reinforcement plate 34 facing away from the circuit board 31. The magnetic member 40 can be made of a magnetic material.

[0174] In some embodiments, a portion of the outer peripheral side surface of the frame portion 10a may be recessed in a direction approaching the inner peripheral side surface, forming a first groove 14. The first groove 14 can be used to accommodate the main plate 31a of the circuit board 31. A portion of the surface of the bottom portion 10b facing away from the frame portion 10a may also be recessed inward to form a second groove 15. The second groove 15 may be connected to the first groove 14. The second groove 15 can be used to accommodate the extension plate 31b of the circuit board 31. In this way, by providing the first groove 14 and the second groove 15 on the base 10 for accommodating the main plate 31a and the extension plate 31b, the overall structure of the circuit board 31 and the base 10 is made more compact.

[0175] Figure 17 is a schematic diagram of the assembled structure of the base 10, housing 20, circuit assembly 30, and magnetic element 40 of the drive motor 1a shown in Figure 11. Figure 18 is a schematic diagram of the structure shown in Figure 17 from another perspective. Figure 19 is a schematic diagram of a partial cross-section of the drive motor 1a shown in Figure 10 taken along line DD in one embodiment.

[0176] As shown in Figures 17 to 19, the housing 20 can be fixed to the base 10. The housing 20 can be provided with a light inlet 20a and a light outlet 20b. Both the light inlet 20a and the light outlet 20b can connect the accommodating space 10c of the base 10 with the space outside the drive motor 1a. The projection of the light inlet 20a in the Z-axis direction can overlap with the bottom 10b of the base 10. The projection of the light outlet 20b in the X-axis direction can overlap with the second side 12 of the base 10. Light can enter the drive motor 1a through the light inlet 20a along a first direction and can exit the drive motor 1a through the light outlet 20b along a second direction. The first direction can intersect with the second direction. For example, the first direction can be perpendicular to the second direction. The first direction can be parallel to the Z-axis direction. The second direction can be parallel to the X-axis direction. The third direction can be perpendicular to the plane containing the first and second directions, that is, parallel to the Y-axis direction. In other embodiments, the second direction can be non-perpendicular to the first direction.

[0177] Exemplarily, the housing 20 may include an outer shell 21, a bottom plate 22, and a cover plate 23. The outer shell 21 may be fixed to the outer peripheral side of the frame portion 10a of the base 10 by bonding or the like. The bottom plate 22 may include a connected main body portion 221 and an extension portion 222. The main body portion 221 of the bottom plate 22 may be fixed to the surface of the bottom 10b of the base 10 facing away from the accommodating space 10c. The extension portion 222 may be spaced apart from the second slide groove 113 (please refer to FIG. 14 ) of the first side portion 11 of the frame portion 10a, and spaced apart from the fourth slide groove 133 of the third side portion 13. At this time, the housing 20 may wrap at least a portion of the circuit assembly 30 and the base 10. A portion of the extension plate 31b of the circuit board 31 may be exposed relative to the housing 20 for electrically connecting to an external power source.

[0178] Exemplarily, the cover plate 23 may include a main body 231, a first branch 232 and a second branch 233. The first branch 232 and the second branch 233 may be located on the same side of the main body 231 and fixedly connected to the main body 231. The first branch 232 may be spaced apart from the second branch 233. The main body 231 may be fixedly connected to the top surface of the frame portion 10a of the base 10. The light inlet 20a may be located in the main body 231. The first branch 232 may be spaced apart from the first slide groove 112 of the first side portion 11 (please refer to Figure 14 for details). The second branch 233 may be spaced apart from the third slide groove 132 of the third side portion 13. At this time, the first branch 232, the second branch 233, the extension portion 222 of the bottom plate 22 and the outer shell 21 may together surround the light outlet 20b of the housing 20.

[0179] In some embodiments, the housing 20 may further include a light shielding gasket 24. The light shielding gasket 24 may be fixed to the surface of the main body 231 of the cover 23 facing away from the base 10. The light shielding gasket 24 may have a first through hole 241. The first through hole 241 may communicate with the light inlet 20a.

[0180] The above specifically introduces part of the structure of the driving motor 1 a . The following will introduce the specific structure of the mover 50 of the driving motor 1 a in various embodiments with reference to the relevant drawings.

[0181] First embodiment: Fig. 20 is a schematic structural diagram of the mover 50 of the driving motor 1a shown in Fig. 11 in a first embodiment. Fig. 21 is a schematic exploded structural diagram of the mover 50 shown in Fig. 20 .

[0182] As shown in Figures 20 and 21, the mover 50 may include a first bracket 51, a second bracket 52, a first set of magnetic members 53, a second set of magnetic members 54, a first set of support members 55, and a second set of support members 56. For ease of understanding, the first set of support members 55 and the second set of support members 56 are framed by dotted lines in Figure 21.

[0183] The first group of support members 55 may include multiple first support members. The multiple first support members may include one or more first balls 551 and one or more second balls 552. The sizes of the multiple first balls 551 may not be exactly the same. The multiple second balls 552 may also not be exactly the same. The second group of support members 56 may include multiple second support members. The multiple second support members may include at least three third balls 561. The sizes of the multiple third balls 561 may be exactly the same. In this embodiment, the number of each of the first balls 551 and the second balls 552 may be three. The number of the third balls 561 may be four.

[0184] Figure 22a is a schematic structural diagram of the first bracket 51 of the mover 50 shown in Figure 21. Figure 22b is a schematic structural diagram of the first bracket 51 shown in Figure 22a from another perspective. Figure 23 is a schematic structural diagram of a partial cross section of the mover 50 shown in Figure 20 taken along line EE in one embodiment.

[0185] As shown in Figures 22a to 23, the first bracket 51 may include a support portion 511, a first sidewall 512, a second sidewall 513, a third sidewall 514, a first connecting portion 515, and a second connecting portion 516. The first sidewall 512 and the second sidewall 513 may be positioned opposite each other and spaced apart. The third sidewall 514 may be fixedly connected between the first and second sidewalls 512, 513. In this case, the first, second, and third sidewalls 512, 513, 514 may generally form a "concave" shape. The support portion 511 may be located between the first and second sidewalls 512, 513, and fixedly connected to the tops of the first, second, and third sidewalls 512, 513, 514. The surface of the support portion 511 facing away from the third sidewall 514 may constitute a mounting slope 511a of the support portion 511. The mounting slope 511a may be arranged at an angle to the Z-axis. The angle between the surface of the support portion 511 facing away from the third side wall 514 and the Z-axis direction may be 45°. In this case, the first side wall 512 , the second side wall 513 and the support portion 511 may together enclose the installation space 51 a of the first bracket 51 .

[0186] For example, the first connecting portion 515 can be located on the side of the first side wall 512 facing away from the second side wall 513, and fixedly connected to the end of the first side wall 512 away from the third side wall 514. The second connecting portion 516 can be located on the side of the second side wall 513 facing away from the first side wall 512, and fixedly connected to the end of the second side wall 513 away from the third side wall 514. It should be understood that in this embodiment, the first bracket 51 is described as being divided into six parts, but this does not affect the first bracket 51 being an integrally formed structure, that is, the support portion 511, the first side wall 512, the third side wall 514, the second side wall 513, the first connecting portion 515, and the second connecting portion 516 can be integrally formed. In other embodiments, the angle between the surface of the support portion 511 facing away from the third side wall 514 and the Z-axis direction can also be other degrees. This application does not specifically limit this.

[0187] For example, the first sidewall 512 may be provided with a first mounting groove 5121. The opening of the first mounting groove 5121 may be formed on the surface of the first sidewall 512 facing away from the second sidewall 513. The second sidewall 513 may be provided with a second mounting groove 5131. The opening of the second mounting groove 5131 may be formed on the surface of the second sidewall 513 facing away from the first sidewall 512. The third sidewall 514 may be provided with a third mounting groove 5141. The opening of the third mounting groove 5141 may be formed on the surface of the third sidewall 514 facing away from the support portion 511.

[0188] Exemplarily, the surface of the first connecting portion 515 facing the third sidewall 514 is a first surface 5151. The first surface 5151 may be arc-shaped. The first connecting portion 515 may be provided with a first sliding groove 5152. The opening of the first sliding groove 5152 may be formed on the first surface 5151. The shape of the first sliding groove 5152 may be arc-shaped. The surface of the second connecting portion 516 facing the third sidewall 514 is a second surface 5161. The shape of the second surface 5161 may be the same as that of the first surface 5151. The second connecting portion 516 may be provided with a second sliding groove 5162. The opening of the second sliding groove 5162 may be formed on the second surface. The shape of the second sliding groove 5162 may be arc-shaped.

[0189] Figure 24 is a schematic diagram of the assembly structure of the first bracket 51, the first set of magnetic members 53, the second set of magnetic members 54, and the plurality of first support members of the mover 50 shown in Figure 21. Figure 25 is a schematic diagram of the structure shown in Figure 24 from another perspective.

[0190] As shown in Figures 24 and 25, the first group of magnetic components 53 can be fixed in the third mounting groove 5141 of the third side wall 514. The second group of magnetic components 54 can include a first sub-magnetic component 541 and a second sub-magnetic component 542. The first sub-magnetic component 541 can be fixed in the first mounting groove 5121 of the first side wall 512. The second sub-magnetic component 542 can be fixed in the second mounting groove 5131 of the second side wall 513. The magnetic field direction of the first sub-magnetic component 541 can be opposite to the magnetic field direction of the second sub-magnetic component 542. At this time, the first group of magnetic components 53 can be arranged in the second direction (also known as the X-axis direction in this embodiment) with the mounting bevel 511a of the first bracket 51. The first sub-magnetic component 541, the mounting bevel 511a of the first bracket 51 and the second sub-magnetic component 542 can be arranged in the third direction (also known as the Y-axis direction in this embodiment) in sequence.

[0191] For example, the first set of magnetic components 53 may include a first magnet 531 and a second magnet 532. Both the first magnet 531 and the second magnet 532 may be monopolar magnets. The polarization direction of the first magnet 531 may be opposite to the polarization direction of the second magnet 532. Polarization direction refers to the direction in which the north pole of the same magnet points to the south pole. For example, the portion of the first magnet 531 facing the first sidewall 512 is the south pole, and the portion of the first magnet 531 facing away from the first sidewall 512 is the north pole. The portion of the second magnet 532 facing the first sidewall 512 may be the north pole. The portion of the second magnet 532 facing away from the first sidewall 512 may be the south pole. The first magnet 531 and the second magnet 532 may be arranged along the Z-axis. The structures of the first sub-magnetic component 541 and the second sub-magnetic component 542 of the second set of magnetic components 54 are substantially the same as those of the first set of magnetic components 53, and the identical parts are not further described. In some embodiments, the first set of magnetic components 53 may include only the first magnet 531. The first magnet 531 may also be a bipolar magnet, that is, the first magnet 531 may include two N poles and two S poles, which may form a magnetic field together.

[0192] Exemplarily, the plurality of first balls 551 in the plurality of first support members can be arranged in the first sliding groove 5152 of the first connecting portion 515. The first sliding groove 5152 can be a "V"-shaped groove, that is, the cross-sectional shape of the first sliding groove 5152 is a "V" shape. At this time, a tight fit can be achieved between the plurality of first balls 551 and the first sliding groove 5152. Exemplarily, the size of the first balls 551 located at both ends of the first sliding groove 5152 among the plurality of first balls 551 can be slightly larger than the size of the other first balls 551 in the first sliding groove 5152. In this way, the smaller first balls 551 can increase the span between the first balls 551 located at both ends of the first sliding groove 5152, and at the same time can prevent the plurality of first balls 551 from getting stuck when sliding in the first sliding groove 5152.

[0193] For example, the plurality of second balls 552 in the plurality of first support members can be disposed in the second sliding groove 5162 of the second connecting portion 516. The second sliding groove 5162 can be a U-shaped groove, that is, the cross-sectional shape of the second sliding groove 5162 is a U-shaped groove. In this case, the plurality of second balls 552 can be loosely fitted into the second sliding groove 5162. For example, the size of the second balls 552 located at both ends of the second sliding groove 5162 can be slightly larger than the size of the other second balls 552 in the first sliding groove 5152.

[0194] In some embodiments, the mover 50 may further include a first reinforcement member 57. The first reinforcement member 57 may be a steel sheet. The first reinforcement member 57 may be embedded in the interior of the first bracket 51 by injection molding or the like. Part of the first reinforcement member 57 may be exposed through the first mounting groove 5121, the second mounting groove 5131, and the third mounting groove 5141 (see Figures 22a and 22b). In this way, the first reinforcement member 57 may enhance the structural strength of the first bracket 51, which is beneficial to extending the service life of the first bracket 51. In some other embodiments, the first reinforcement member 57 may also have magnetic conductivity, which is beneficial to enhancing the magnetic field strength of the first group of magnetic members 53 and the second group of magnetic members 54.

[0195] In some embodiments, the first sliding groove 5152 may be a U-shaped groove, and the second sliding groove 5162 may be a V-shaped groove. Alternatively, both the first sliding groove 5152 and the second sliding groove 5162 may be V-shaped grooves. In other words, at least one of the first sliding groove 5152 and the second sliding groove 5162 may be a V-shaped groove.

[0196] Fig. 26 is a schematic structural diagram of the second bracket 52 of the mover 50 shown in Fig. 21. Fig. 27 is a schematic structural diagram of the assembly of the second bracket 52 and the second set of support members 56 shown in Fig. 26 from another perspective.

[0197] As shown in Figures 26 and 27, the second bracket 52 may include a first portion 521, a second portion 522, and a third portion 523. The first portion 521 and the second portion 522 may be arranged opposite each other and spaced apart. The shape of the first portion 521 and the shape of the second portion 522 may be substantially the same. The third portion 523 may be fixedly connected between the first portion 521 and the second portion 522.

[0198] For example, the first portion 521 may include a first end portion 5211, a middle portion 5212, and a second end portion 5213. The middle portion 5212 may be fixedly connected between the first end portion 5211 and the second end portion 5213. The middle portion 5212 may be raised along one side relative to the first end portion 5211 and the second end portion 5213. In this case, the first end portion 5211, the middle portion 5212, and the second end portion 5213 may collectively enclose a first space 521a.

[0199] For example, the middle portion 5212 of the first portion 521 may be provided with a first guide groove 5214. The projection of the opening of the first guide groove 5214 in the X-axis direction may overlap with the first portion 521. The opening of the first guide groove 5214 may communicate with the first space 521a. The first guide groove 5214 may be an arc-shaped groove. The first end 5211 of the first portion 521 may be provided with a third guide groove 5215. The second end 5213 of the first portion 521 may be provided with a fourth guide groove 5216. The opening of the third guide groove 5215 may face the same direction as the opening of the fourth guide groove 5216, and opposite to the direction of the opening of the first guide groove 5214.

[0200] For example, the second portion 522 may include a first end portion 5221, a middle portion 5222, and a second end portion 5223. The structure of the second portion 522 is substantially the same as that of the first portion 521, and the identical parts are not further described. The first end portion 5221, the middle portion 5222, and the second end portion 5223 of the second portion 522 may collectively enclose a second space 522a. The middle portion 5222 of the second portion 522 may be provided with a second guide groove 5224. The projection of the opening of the second guide groove 5224 in the X-axis direction may overlap with that of the second portion 522. The second guide groove 5224 may communicate with the second space 522a. The second guide groove 5224 may be an arc-shaped groove. The first end portion 5221 of the second portion 522 may be provided with a fifth guide groove 5225. The second end portion 5223 of the second portion 522 may be provided with a sixth guide groove 5226. The direction of the opening of the fifth guide groove 5225 may be the same as the direction of the opening of the sixth guide groove 5226 and the direction of the opening of the third guide groove 5215 , and opposite to the direction of the opening of the second guide groove 5224 .

[0201] For example, the first end 5211 of the first portion 521 can be disposed opposite the first end 5221 of the second portion 522. The third portion 523 can be fixedly connected between the second end 5213 of the first portion 521 and the second end 5223 of the second portion 522. In this case, the second bracket 52 can be substantially in the shape of a "concave" character.

[0202] Exemplarily, a plurality of second support members (ie, a plurality of third balls 561 in this embodiment) may be disposed in the third guide groove 5215 , the fourth guide groove 5216 , the fifth guide groove 5225 , and the sixth guide groove 5226 in a one-to-one correspondence.

[0203] Fig. 28 is a schematic diagram of a cross-sectional structure of the mover 50 shown in Fig. 20 taken along line F1-F1 in one embodiment. Fig. 29 is a schematic diagram of a cross-sectional structure of the mover 50 shown in Fig. 20 taken along line F2-F2 in one embodiment.

[0204] As shown in Figures 28 and 29, the first connecting portion 515 of the first bracket 51 can be mounted in the first space 521a of the first portion 521. The first connecting portion 515 can be rotatably connected to the first portion 521 of the second bracket 52 via a plurality of first balls 551. Specifically, the plurality of first balls 551 can be connected between the first connecting portion 515 and the wall surface of the first space 521a. In this case, the first portion 521 can semi-enclose the first connecting portion 515. This makes the structure of the first portion 521 and the first connecting portion 515 more compact, facilitating a miniaturized design of the drive motor 1a.

[0205] For example, the opening of the first sliding groove 5152 of the first connecting portion 515 and the opening of the first guide groove 5214 of the first portion 521 can be arranged opposite each other. The first sliding groove 5152 and the first guide groove 5214 can together form the first ball rolling groove 501. The first ball rolling groove 501 can be arc-shaped. In this case, the center of the circle containing the centers of the multiple first balls 551 is the first rotation center O1. The first connecting portion 515 of the first bracket 51 can rotate about the first rotation center O1 relative to the first portion 521 of the second bracket 52. It should be understood that when the multiple first balls 551 are of different sizes (for example, the first balls 551 at both ends of the first ball rolling groove 501 are larger than the remaining first balls 551), the center of the circle containing the centers of the larger first balls 551 can be used as the first rotation center O1. In some embodiments, the center of the circle containing the groove wall fitting curve of the first ball rolling groove 501 can also be used as the first rotation center O1.

[0206] For example, the second connecting portion 516 of the first bracket 51 can be installed in the second space 522a of the second portion 522. The second connecting portion 516 can be rotatably connected to the second portion 522 of the second bracket 52 via a plurality of second balls 552. In this case, the second portion 522 can half-surround the second connecting portion 516.

[0207] For example, the opening of the second sliding groove 5162 of the second connecting portion 516 and the opening of the second guide groove 5224 of the second portion 522 can be arranged opposite each other. The second sliding groove 5162 and the second guide groove 5224 can together form the second ball rolling groove 502. The second ball rolling groove 502 can be arc-shaped. In this case, the center of the circle containing the centers of the plurality of second balls 552 forms the second rotation center O2. The second connecting portion 516 of the first bracket 51 can rotate relative to the second portion 522 of the second bracket 52 about the second rotation center O2.

[0208] Illustratively, the line connecting the first rotation center O1 and the second rotation center O2 may coincide with the first axis R1. The first axis R1 may be parallel to the Y-axis. The first bracket 51 may rotate about the first axis R1 relative to the second bracket 52. Illustratively, the first axis R1 may pass through the first connecting portion 515 and the second connecting portion 516. In some embodiments, the first axis R1 may not pass through the first connecting portion 515 and the second connecting portion 516. The first axis R1 may also be located on the side of the first connecting portion 515 and the second connecting portion 516 facing away from the inclined mounting surface 511a.

[0209] Exemplarily, one of the first guide groove 5214 and the second guide groove 5224 can be a "V"-shaped groove. In this way, on the one hand, one of the first guide groove 5214 and the second guide groove 5224 is a "V"-shaped groove, which can automatically correct the relative position of the actual first rotation center N1 and the theoretical first rotation center N1, thereby making the movement of the first bracket 51 relative to the second bracket 52 smoother; on the other hand, it can also avoid the first guide groove 5214 and the second guide groove 5224 being "V"-shaped grooves, which may cause the first bracket 51 to get stuck when rotating relative to the second bracket 52. In other embodiments, one of the first sliding groove 5152 and the second sliding groove 5162 of the first bracket 51 can also be a "V"-shaped groove. At least one of the first guide and second guide grooves 5224 of the second bracket 52 is a "V"-shaped groove.

[0210] Figure 30 is a schematic diagram of a portion of the drive motor 1a shown in Figure 10 from another perspective. Figure 31a is a schematic diagram of a cross-sectional structure of one embodiment of the drive motor 1a shown in Figure 10 taken along line DD. Figure 31b is a schematic diagram of a cross-sectional structure of one embodiment of the drive motor 1a shown in Figure 10 taken along line CC. The drive motor 1a shown in Figure 30 conceals a portion of the housing 20.

[0211] As shown in Figures 30 to 31b, the mover 50 can be housed within the housing 20 and mounted on the base 10. The support portion 511, first sidewall 512, third sidewall 514, and second sidewall 513 of the first bracket 51 can all be located within the accommodating space 10c of the base 10. The first sidewall 512 of the first bracket 51 can be positioned opposite and spaced from the first side portion 11 of the base 10. The third sidewall 514 of the first bracket 51 can be positioned opposite and spaced from the second side portion 12 of the base 10. The second sidewall 513 of the first bracket 51 can be positioned opposite and spaced from the third side portion 13 of the base 10. In this case, the first drive coil 321 can be positioned opposite the first set of magnetic components 53. The first sub-coil 3221 of the second drive coil 322 can be positioned opposite the first sub-magnetic component 541 of the second set of magnetic components 54. The second sub-coil 3222 of the second drive coil 322 can be positioned opposite the second sub-magnetic component 542 of the second set of magnetic components 54. The first bracket 51 can be arranged in a first direction (also the Z-axis direction in this embodiment) with the light inlet 20a. The first bracket 51 can be arranged in a second direction (also the X-axis direction in this embodiment) with the light outlet 20b. At this time, the installation space 51a of the first bracket 51 can be connected to the light inlet 20a and the light outlet 20b of the housing 20. The installation bevel 511a of the first bracket 51 can face the light inlet 20a and the light outlet 20b. The first axis R1 can be located on the side of the installation bevel 511a of the first bracket 51 close to the light outlet 20b of the housing 20, that is, the installation side 51b of the first bracket 51. The installation space 51a can be located on the installation side 51b of the installation bevel 511a.

[0212] Figure 32 is a schematic diagram of the cross-sectional structure of the drive motor 1a shown in Figure 10 taken along line G1-G1 in one embodiment. Figure 33 is a schematic diagram of the cross-sectional structure of the drive motor 1a shown in Figure 10 taken along line G2-G2 in one embodiment. Figure 34 is a schematic diagram of the cross-sectional structure of the drive motor 1a shown in Figure 10 taken along line HH in one embodiment.

[0213] As shown in Figures 32 to 34, the second bracket 52 can be located on a side of the base 10 near the light exit hole 20b of the housing 20. The second bracket 52 can be rotatably connected to the base 10 via a plurality of third rolling balls 561. The opening of the third guide groove 5215 of the second bracket 52 can be arranged opposite the opening of the first slide groove 112 of the base 10. The third guide groove 5215 and the first slide groove 112 can together form a third ball rolling groove 503. The opening of the fourth guide groove 5216 of the second bracket 52 can be arranged opposite the opening of the second slide groove 113 of the base 10. The fourth guide groove 5216 and the second slide groove 113 can together form a fourth ball rolling groove 504. The opening of the fifth guide groove 5225 of the second bracket 52 can be arranged opposite the opening of the third slide groove 132 of the base 10. The fifth guide groove 5225 and the third slide groove 132 can together form a fifth ball rolling groove 505. The opening of the sixth guide groove 5226 of the second bracket 52 can be arranged opposite to the opening of the fourth sliding groove 133 of the base 10. The sixth guide groove 5226 and the fourth sliding groove 133 can together form the sixth ball rolling groove 506. The four third balls 561 can be located in the third ball rolling groove 503, the fourth ball rolling groove 504, the fifth ball rolling groove 505, and the sixth ball rolling groove 506 in a one-to-one correspondence.

[0214] The first portion 521 of the second bracket 52 can be rotatably connected to the first side portion 11 of the base 10 via some third balls 561. The second portion 522 of the second bracket 52 can be rotatably connected to the third side portion 13 of the base 10 via another portion of the third balls 561. The centers of the multiple third balls 561 can be located on the same plane. The center of the circle containing the centers of the multiple third balls 561 is the third rotation center O3, which is also the center of the second group of support members 56. The second axis R2 can pass perpendicularly through the plane containing the centers of the multiple third balls 561. The second axis R2 can also pass through the third rotation center O3. At this time, the second bracket 52 can rotate relative to the base 10 about the second axis R2. The third rotation center O3 can be located on the side of the mounting bevel 511a of the first bracket 51 closer to the light exit hole 20b, that is, the mounting side 51b of the first bracket 51. The second axis R2 can pass through the mounting bevel 511a and be parallel to the second direction (i.e., the X-axis direction in this embodiment).

[0215] Exemplarily, two of the third guide groove 5215, the fourth guide groove 5216, the fifth guide groove 5225, and the sixth guide groove 5226 may be V-shaped grooves. Thus, 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 of the actual third rotation center O3 and the theoretical third rotation center O3, thereby making the second bracket 52 rotate more smoothly relative to the base 10. On the other hand, this can also prevent the third guide groove 5215, the fourth guide groove 5216, the fifth guide groove 5225, and the sixth guide groove 5226 from being all V-shaped grooves, or three of them being V-shaped grooves, which could cause the second bracket 52 to become stuck during rotation relative to the base 10. In other embodiments, two of the first guide groove 112, the second guide groove 113, the third guide groove 132, and the fourth guide groove 133 of the first bracket 51 may be V-shaped grooves. At least two of the third guide groove 5215 , the fourth guide groove 5216 , the fifth guide groove 5225 and the sixth guide groove 5226 of the second bracket 52 are V-shaped grooves.

[0216] In some embodiments, the middle portion 5212 of the first portion 521 can be located within the first avoidance groove 114 of the first side portion 11. The middle portion 5222 of the second portion 522 can be located within the second avoidance groove 134 of the third side portion 13. In this way, the first side portion 11 of the base 10 can semi-enclose the first portion 521 of the second bracket 52. The third side portion 13 of the base 10 can semi-enclose the second portion 522 of the second bracket 52. The second bracket 52 can utilize the length of the base 10, making the arrangement of the second bracket 52 and the base 10 more compact, thereby facilitating a miniaturized arrangement of the drive motor 1a.

[0217] As shown in Figures 31a, 32 and 33, the magnetic attraction component 40 can generate a magnetic attraction force along the X-axis direction with the first group of magnetic components 53, thereby providing pre-pressure for the mover 50, so that the multiple first balls 551 and the second balls 552 can maintain contact with the first bracket 51 and the second bracket 52, and at the same time, the multiple third balls 561 can maintain contact with the second bracket 52 and the base 10.

[0218] Figure 35a is a schematic diagram of a cross-sectional structure of an embodiment of the anti-shake assembly 1 shown in Figure 3 taken along line B1-B1. Figure 35b is a schematic diagram of a cross-sectional structure of an embodiment of the anti-shake assembly 1 shown in Figure 3 taken along line B2-B2.

[0219] As shown in Figures 35a and 35b, the first optical element 1b can be installed in the installation space 51a of the first bracket 51. For example, the first optical element 1b can be fixedly connected to the first side wall 512 and the second side wall 513 of the first bracket 51 by bonding or other means. The reflective surface 102 of the first optical element 1b can face the mounting bevel 511a of the first bracket 51. It should be noted that when the first optical element 1b is installed in the first bracket 51 and the reflective surface 102 of the first optical element 1b is directly opposite the mounting bevel 511a, the reflective surface 102 of the first optical element 1b and the mounting bevel 511a can be in contact with each other, or a small gap can exist between them. This small gap can be formed by an air gap or the thickness of a fixing member (such as an adhesive layer). In this case, the small gap between the reflective surface 102 and the mounting bevel 511a can be ignored, and the reflective surface 102 and the mounting bevel 511a can be considered to coincide with each other. That is, the first axis R1 can be located on the side of the reflective surface 102 closer to the light exit hole 20b.

[0220] For example, the light input axis T1 of the first optical element 1b may pass through the light input hole 20a and the mounting bevel 511a. The light input axis T1 may be parallel to the first direction (i.e., the Z-axis direction in this embodiment). The light output axis T2 of the first optical element 1b may pass through the mounting bevel 511a and the light output hole 20b. The light output axis T2 may be parallel to the second direction (i.e., the X-axis direction in this embodiment). The first axis R1 may be perpendicular to the plane where the light input axis T1 and the light output axis T2 are located. The second axis R2 may coincide with the light output axis T2.

[0221] For example, the distance between the first axis R1 and the installation inclined surface 511 a may be greater than 0.01 mm. In some embodiments, the distance between the first axis R1 and the installation inclined surface 511 a may be greater than or equal to 5 mm.

[0222] For example, the center of gravity of the mover 50 and the first optical element 1b as a whole can be located on the side of the mounting bevel 511a of the mover 50 close to the light exit hole 20b, that is, the mounting side 51b of the first bracket 51. 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 mm. 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 to be the center of gravity of the first bracket 51, the second bracket 52, and the first optical element 1b of the mover 50 as a whole.

[0223] For example, the first axis R1 may intersect the second axis R2. In some embodiments, both the first axis R1 and the second axis R2 may pass through the third rotation center O3 and coincide with each other. In other embodiments, the first axis R1 may not intersect the second axis R2. This application is not limited to this.

[0224] When a signal is applied to the first drive coil 321, the first group of magnetic components 53 can cooperate with the first drive coil 321 to generate a driving force along the Z-axis direction, thereby driving the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1, that is, the first bracket 51 rotates relative to the stator around the first axis R1. At this time, the first group of magnetic components 53 and the first drive coil 321 can together constitute the first driving mechanism of the drive motor 1a. The second sensor 332 can cooperate with the first group of magnetic components 53 to detect the magnetic field strength of the first group of magnetic components 53 at different angles of rotation of the first bracket 51 around the first axis R1, so as to detect the angle of rotation of the first bracket 51 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, thereby achieving anti-shake.

[0225] When a signal is applied to the second drive coil 322, the first sub-magnetic member 541 of the second set of magnetic members 54 can 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 member 542 of the second set of magnetic members 54 can 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 opposite to the direction of the second driving force, thereby driving the first bracket 51 and the second bracket 52 to rotate relative to the base 10 about the second axis R2. In other words, the first bracket 51 can drive the second bracket 52 to rotate relative to the stator about the second axis R2. At this time, the second set of magnetic members 54 and the second drive coil 322 can jointly constitute the second drive mechanism of the drive motor 1a. The first sensor 331 can cooperate with the first sub-magnetic member 541, and the third sensor 333 can cooperate with the second sub-magnetic member 542 to jointly detect the magnetic field strength when the first bracket 51 rotates at different angles about the second axis R2, thereby detecting the angle of rotation of the first bracket 51 about the second axis R2. In other words, the first optical element 1 b can rotate relative to the stator around the second axis R2 under the action of the mover 50 , thereby achieving anti-shake.

[0226] It can be understood that compared to some driving motors, the mover drives the first optical element to rotate relative to the stator around the first axis, and rotates around the second axis to achieve the optical image stabilization function. Among them, the first axis is parallel to the Y-axis direction. The first axis is located on the mounting bevel of the mover, or on the side of the mounting bevel facing away from the light exit hole. The second axis is parallel to the Z-axis direction. This makes the focus offset larger when the driving motor drives the first optical element to rotate around the first axis and / or around the second axis for optical image stabilization, causing the modulation transfer function of the entire camera module to drop significantly, the anti-shake accuracy is low, and the imaging quality is affected. The first axis R1 of the driving motor 1a in this embodiment is located on the side of the mounting bevel 511a close to the light exit hole 20b, that is, the mounting side 51b of the mounting bevel 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 focus offset is small, which can effectively reduce the influence of the focus offset on the modulation transfer function, which is beneficial to improving the anti-shake accuracy 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 around the second axis R2 relative to the stator, 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 component 1 can always remain perpendicular to the light-emitting axis T2, thereby effectively reducing the inclination angle between the anti-shake component 1 and the focusing component 2, reducing the focus offset, and improving the anti-shake accuracy of the entire camera module 100. The optical quality of the camera module 100 is high, which is beneficial to improving the imaging quality.

[0227] In other words, the driving motor 1a in this embodiment sets 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 is located on the mounting side 51b of the mounting slope 511a of the mover 50, thereby effectively improving the overall anti-shake accuracy of the driving motor 1a, reducing the impact on the modulation transfer function, and helping to improve the imaging quality of the camera module 100.

[0228] Secondly, in this embodiment, when the mover 50 of the drive motor 1a drives the stator to rotate about the second axis R2, the third rotation center O3 is located on the mounting side 51b of the mover 50's mounting bevel 511a, placing the third rotation center O3 closer to the center of gravity of the mover 50 and the first optical element 1b. This effectively enhances the anti-interference capability of the drive motor 1a during anti-shake rotation about the second axis R2 and reduces its power consumption, extending the battery life of the electronic device 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 can be less than or equal to 0.03 mm.

[0229] In addition, compared to the driving motor in which the first axis is parallel to the Y-axis direction and the first axis is located on the mounting bevel of the mover, or on the side of the mounting bevel facing away from the light exit hole, the first axis R1 of the driving motor 1a in this embodiment is located on the mounting side 51b of the mounting bevel 511a, thereby increasing the distance between the first group of magnetic parts 53 and the first axis R1, that is, increasing the driving force arm when the first group of magnetic parts 53 drives the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1. 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 this embodiment can generate a greater thrust for anti-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 in this embodiment can bear the heavier first optical element 1b, which is beneficial to improving the optical quality of the entire camera module 100.

[0230] In addition, the multiple groups of magnetic components of the driving motor 1a in this embodiment (i.e., the first group of magnetic components 53 and the second group of magnetic components 54 in this embodiment) are all arranged on the first bracket 51, so that integrated transmission can be achieved, which is beneficial to improving the smoothness of the operation of the driving motor 1a during anti-shake performance.

[0231] In some embodiments, the end of the third side wall 514 of the first bracket 51 away from the light inlet 20a can be provided with an anti-collision protrusion 5142 (Figures 22a and 22b also illustrate the anti-collision protrusion 5142 from another perspective). The second side portion 12 of the base 10 can be provided with a limiting hole 122 (Figure 14 also illustrates the limiting hole 122 from another perspective). At least a portion of the anti-collision protrusion 5142 of the first bracket 51 can be located within the limiting hole 122 of the base 10. In this way, when the first bracket 51 rotates relative to the base 10 around the first axis R1, the anti-collision protrusion 5142 can cooperate with the limiting hole 122, thereby effectively preventing the first bracket 51 from rotating relative to the base 10 around the first axis R1 at an excessively large angle, which would cause the first optical element 1b to collide with the stator of the drive motor 1a and be damaged, thereby helping to extend the service life of the camera module 100.

[0232] In other embodiments, as shown in Figures 36a and 36b, 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 provided toward the first sidewall 512 of the first bracket 51. The second protrusion 2222 may be provided 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. In this way, when the first bracket 51 rotates relative to the stator around the second axis R2 (please refer to Figure 35a) under the action of the second bracket 52, the first protrusion 2221 can cooperate with the first limiting groove 512a, and the second protrusion 2222 can cooperate with the second limiting groove 513a, thereby effectively avoiding the first bracket 51 from rotating too much relative to the stator around the second axis R2, causing the first optical element 1b to collide with the stator of the drive motor 1a and be damaged, which is beneficial to extending the service life of the camera module 100.

[0233] Fig. 37 is a schematic cross-sectional view of another embodiment of the drive motor 1a shown in Fig. 10 taken along line DD. Fig. 38 is a schematic cross-sectional view of another embodiment of the drive motor 1a shown in Fig. 10 taken along line CC.

[0234] As shown in Figures 37 and 38, the structure of the drive motor 1a in this embodiment is substantially the same as that of the drive motor 1a shown in Figure 10, and the identical parts are not further described. The difference is that the first set of magnetic components 53 of the drive motor 1a in this embodiment may also include a third magnet 533. The third magnet 533 may 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 may be arranged sequentially along the Z-axis. The third magnet 533 may be a unipolar magnet. The polarization direction of the third magnet 533 may be perpendicular to the polarization direction of the first magnet 531. For example, the portion of the first magnet 531 facing the first side wall 512 may have an S pole, and the portion of the first magnet 531 facing away from the first side wall 512 may have an N pole. The portion of the second magnet 532 facing the first side wall 512 may have an S pole, and the portion of the second magnet 532 facing away from the first side wall 512 may have an N pole. The portion of the third magnet 533 facing the first magnet 531 may have an N pole. The portion of the third magnet 533 facing the second magnet 532 may have an S pole. In this case, the multiple magnets of the first set of magnetic members 53 (i.e., the first magnet 531, the second magnet 532, and the third magnet 533 in this embodiment) may form a Halbach array.

[0235] It can be understood that the first group of magnetic parts 53 in this embodiment adopts a Halbach array to set up multiple magnets. Under the condition that the overall size of the first group of magnetic parts 53 is the same, the driving force generated by the first group of magnetic parts 53 using the Halbach array and the first drive coil 321 in this embodiment is greater. 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 in this embodiment can drive the first optical element 1b to rotate a larger angle around the first axis R1 (please refer to Figure 35a) to achieve large-angle anti-shake. Under the condition that the rotation angle is the same, the mover 50 in this embodiment can bear the heavier first optical element 1b, which is beneficial to improving the optical quality of the entire camera module 100.

[0236] In some embodiments, the first sub-magnetic member 541 and the second sub-magnetic member 542 of the second set of magnetic members 54 can also be configured with multiple magnets using a Halbach array. The magnetic field direction of the first sub-magnetic member 541 can be opposite to the magnetic field direction of the second sub-magnetic member 542. The structures of the first sub-magnetic member 541 and the second sub-magnetic member 542 are substantially the same as those of the first set of magnetic members 53, and the identical parts are not repeated here.

[0237] In some embodiments, the first set of magnetic components 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 and the second bracket 52 to rotate relative to the base 10 about the second axis R2. In this case, the first set of magnetic components 53 and the first drive coil 321 can jointly constitute the second drive mechanism of the drive motor 1a. The first sub-magnetic component 541 of the second set of magnetic components 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 component 542 of the second set of magnetic components 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. In this way, the first sub-magnetic component 541 and the second sub-magnetic component 542 of the second set of magnetic components 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 about the first axis R1. At this time, the second set of magnetic components 54 and the second driving coil 322 can together constitute the first driving mechanism of the driving motor 1 a.

[0238] In other embodiments, the first group of magnetic components 53 and the first drive coil 321 can also be set on the side of the first bracket 51 facing away from the light inlet 20a. The first group of magnetic components 53 can generate a driving force along the X-axis direction with the first drive coil 321, thereby driving the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1. Alternatively, the positions of the first group of magnetic components 53 and the first drive coil 321 can remain unchanged, and a fourth group of magnetic components and a third drive coil can be set on the side of the first bracket 51 facing away from the light inlet 20a. The fourth group of magnetic components can cooperate with the third drive coil to generate a driving force along the X-axis direction. In this way, the first group of magnetic components 53 and the fourth group of magnetic components can respectively cooperate with the first drive coil 321 and the third drive coil to jointly drive the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1, which is beneficial to increase the driving force for the rotation of the first bracket 51 relative to the second bracket 52 and achieve large-angle anti-shake.

[0239] Fig. 39 is a schematic cross-sectional view of another embodiment of the anti-shake assembly 1 shown in Fig. 3 taken along line B1-B1. Fig. 40 is a schematic diagram of a partially exploded structure of the anti-shake assembly 1 shown in Fig. 39.

[0240] As shown in Figures 39 and 40, the structure of the anti-shake component 1 in this embodiment is substantially the same as the structure of the anti-shake component 1 shown in Figure 3, and the identical parts will not be repeated. The following will mainly introduce the differences between the two. The optical path folding element 104 of the anti-shake component 1 in this embodiment can be a reflective plane mirror. The reflective plane mirror can include a reflective surface 1044 and a mounting surface 1045 arranged in opposite directions. The reflective surface 1044 of the reflective plane mirror can face the light inlet 20a and the light outlet 20b. The mounting surface 1045 of the optical path folding element 104 can face the mounting bevel 511a of the first bracket 51. The mounting surface 1045 of the optical path folding element 104 can be fixedly connected to the mounting bevel 511a of the first bracket 51. The reflective surface 1044 of the optical path folding element 104 can be arranged at an angle to the surface of the first lens 105 facing the optical path folding element 104. For example, the reflective surface 1044 can be arranged at a 45° angle to the surface of the first lens 105 facing the optical path folding element 104. In this case, the reflective surface 1044 of the reflective plane mirror may constitute the reflective surface 102 of the first optical element 1 b .

[0241] It can be understood that, compared to the anti-shake component in which the optical path folding element is a reflective prism, the first surface, the second surface and the third surface of the reflective prism are all solid surfaces, and the transmission of light between the first surface and the third surface is all located inside the reflective prism. The refractive index inside the reflective prism is relatively high, which increases the optical path requirement of the entire camera module, the focusing path of the focusing component is longer, and the overall size of the module is longer. In this embodiment, the optical path folding element 104 is a reflective plane mirror, and the reflecting surface 1044 of the optical path folding element 104 is exposed to the air. In this way, the transmission of light between the light inlet 20a and the light outlet 20b is all located in the air. The low refractive index in the air is conducive to reducing the optical path requirement of the camera module 100, thereby shortening the focusing path of the focusing component 2, and helping to reduce the overall size of the module in the X-axis direction, thereby realizing a miniaturized setting of the camera module 100.

[0242] In some embodiments, as shown in Figures 40 to 42, Figure 41 is a schematic diagram of the assembly structure of the first optical element 1b and the optical mounting member 70 of the anti-shake assembly 1 shown in Figure 40. Figure 42 is a schematic diagram of the cross-sectional structure of the assembly structure of the optical mounting member 70 and a portion of the drive motor 1a of the anti-shake assembly 1b shown in Figure 40 in some embodiments.

[0243] Exemplarily, the driving motor 1a may further include an optical mounting member 70. The optical mounting member 70 may be a steel sheet. The strength of the optical mounting member 70 may be greater than the strength of the portion of the first bracket 51 where the mounting bevel 511a is located. At least a portion of the optical mounting member 70 may be located between the optical path folding element 104 and the mounting bevel 511a. In other words, the optical path folding element 104 may be indirectly fixed to the mounting bevel 511a through the optical mounting member 70. In this way, compared to the direct contact between the optical path folding element 104 and the mounting bevel 511a of the first bracket 51, the strength of the portion of the first bracket 51 where the mounting bevel 511a is located is lower, making the portion where the mounting bevel 511a is located susceptible to deformation due to impact or in a high temperature environment, thereby affecting the surface accuracy of the contact surface between the optical path folding element 104 and the mounting bevel 511a (i.e., the mounting surface 1045 of the optical path folding element 104 in this embodiment) and reducing the optical quality. In this embodiment, the optical path folding element 104 is indirectly fixed to the mounting bevel 511a via the optical mounting member 70. There is no direct contact between the optical path folding element 104 and the mounting bevel 511a. Furthermore, the optical mounting member 70 is relatively strong, making it less susceptible to deformation due to impact or high temperature conditions. This helps ensure the surface accuracy of the contact surface between the optical path folding element 104 and the optical mounting member 70 (i.e., the mounting surface 1045 of the optical path folding element 104 in this embodiment), thereby ensuring the optical quality of the optical path folding element 104. In other embodiments, the optical mounting member 70 may also be an adhesive layer. The optical path folding element 104 may be adhesively fixed to the mounting bevel 511a via the optical mounting member 70.

[0244] Exemplarily, the optical mounting member 70 may include a first mounting member 71 and a second mounting member 72. The first mounting member 71 may 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 mounting member 71 may be fixedly connected to the surface of the first bracket 51 facing away from the bottom 10b of the base 10. The second limiting portion 712 of the first mounting member 71 may be fixedly connected to the surface of the first sidewall 512 of the first bracket 51 facing away from the third sidewall 514. The mounting portion 714 of the first mounting member 71 may be fixedly connected to the mounting inclined surface 511a of the first bracket 51. The connecting portion 713 of the first mounting member 71 may 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 mounting member 72 is substantially the same as that of the first mounting member 71, and the identical parts will not be repeated here. The second limiting portion 712 of the second mounting member 72 may be fixedly connected to the surface of the second sidewall 513 facing away from the third sidewall 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 mounting member 71 facing away from the mounting inclined surface 511a and the surface of the mounting portion 724 of the second mounting member 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 mounting member 71 and the first limiting portion 721 of the second mounting member 72.

[0245] It can be understood that compared to the optical mounting member 70 which is a whole, that is, the first mounting member 71 and the second mounting member 72 are integrally formed. When the driving motor 1a is hit, the stress of the optical mounting member 70 is more concentrated and will be 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 this embodiment, the optical mounting member 70 is set as two independent and separately arranged first mounting members 71 and second mounting members 72. In this way, when the driving motor 1a is hit, the first mounting member 71 and the second mounting member 72 can respectively withstand stress in different directions, thereby preventing the first optical element 1b from being pulled by stress in different directions, thereby reducing its own surface accuracy and affecting the optical quality.

[0246] Secondly, the optical mount 70 cooperates with the first bracket 51 by setting a plurality of limiting parts, which on the one hand increases the fixing area of ​​the optical mount 70, the first bracket 51 and the first optical element 1b, which is beneficial to improving the structural stability between the optical mount 70, the first optical element 1b and the mover 50; on the other hand, the setting of multiple limiting parts also facilitates the positioning and assembly between the optical mount 70, the first optical element 1b and the mover 50, which is beneficial to improving the assembly accuracy.

[0247] Illustratively, the connection portion 713 of the first mounting member 71 can be bent in a direction away from the mounting portion 714. At this time, the connection portion 713 of the first mounting member 71 can be roughly bent into a "U" shape. The first bracket 51 can also be provided with a fourth avoidance hole 517. A portion of the connection portion 713 of the first mounting member 71 can be located in the fourth avoidance hole 517. In this way, by bending part of the first mounting member 71, the first mounting member 71 can also have the function of buffering and releasing stress, thereby effectively improving the overall structural stability of the anti-shake assembly 1. At the same time, the first bracket 51 is also provided with a fourth avoidance hole 517 for avoiding the connection 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 conducive to the miniaturization of the drive motor 1a.

[0248] For example, the connecting portion 713 of the second mounting member 72 can be bent in a direction away from the mounting portion 714. In this case, the connecting portion 713 of the second mounting member 72 can also be bent into a generally U-shape. The first bracket 51 can also be provided with a fifth avoidance hole 518. A portion of the connecting portion 713 of the second mounting member 72 can be positioned within the fifth avoidance hole 518.

[0249] In some embodiments, the connection portion 713 of the first mounting member 71 may be provided with one or more through holes, so that the first mounting member 71 can better buffer and release stress.

[0250] The above text, in conjunction with the relevant drawings, specifically introduces an implementation method of the mover 50 of the driving motor 1a, as well as the arrangement of the driving motor 1a including the mover 50 in various anti-shake components 1. The following text will introduce several arrangement methods of the mover 50 of the driving motor 1a in conjunction with the relevant drawings.

[0251] In the second embodiment, the technical details common to the first embodiment are not further described: FIG43 is a schematic diagram of the structure of the mover 50 shown in FIG20 in the second embodiment. FIG44 is a schematic diagram of the exploded structure of the mover 50 shown in FIG43. FIG45 is a schematic diagram of the structure of the first bracket 51 of the mover 50 shown in FIG44 from another perspective. FIG46 is a schematic diagram of the structure of the second bracket 52 of the mover 50 shown in FIG44 from another perspective.

[0252] As shown in Figures 43 to 46, the first bracket 51 in this embodiment may not have the first and second mounting slots. The second bracket 52 may also have a fourth mounting slot 5217 and a fifth mounting slot 5227. The fourth mounting slot 5217 may be provided in the middle portion 5212 of the first portion 521 of the second bracket 52. The opening of the fourth mounting slot 5217 may 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 may be provided in the middle portion 5222 of the second portion 522 of the second bracket 52. The opening of the fifth mounting slot 5227 may 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 may further include a magnetic conductive member 58. The magnetic conductive member 58 may be fixed to the third mounting slot 5141 of the first bracket 51.

[0253] For example, the mover 50 may further include a second reinforcing member 59. The second reinforcing member 59 may be a steel sheet. The second reinforcing member 59 may be magnetically conductive. The second reinforcing member 59 may be embedded within the second bracket 52 by injection molding or other methods. A portion of the second reinforcing member 59 may be exposed through the fourth mounting slot 5217 and the fifth mounting slot 5227.

[0254] Fig. 47 is a schematic cross-sectional view of the drive motor 1a shown in Fig. 10 in a second embodiment, taken along line DD. Fig. 48 is a schematic cross-sectional view of the drive motor 1a shown in Fig. 10 in a second embodiment, taken along line CC.

[0255] As shown in Figures 47 and 48, 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 are respectively located in the fourth mounting groove 5217 and the fifth mounting groove 5227. The first group of magnetic members 53 can be fixed to the first bracket 51 and are located in the third mounting groove 5141. At this time, the first group of magnetic members 53 can be arranged in the second direction (also the X-axis direction in this embodiment) with the mounting bevel 511a of the first bracket 51. The first sub-magnetic member 541, the mounting bevel 511a of the first bracket 51 and the second sub-magnetic member 542 can be arranged in the third direction (also the Y-axis direction in this embodiment) in sequence.

[0256] When a signal is applied to the first drive coil 321, the first set of magnetic members 53 cooperates with the first drive coil 321 to generate a driving force along the Z-axis, thereby driving the first bracket 51 to rotate relative to the second bracket 52 about the first axis R1. In other words, the first bracket 51 rotates relative to the stator about the first axis R1. In other words, the first optical element 1b can be rotated relative to the stator about the first axis R1 under the action of the mover 50, thereby achieving anti-shake.

[0257] When a signal is applied to the second drive coil 322, the first sub-magnetic component 541 of the second group of magnetic components 54 can cooperate with the first sub-coil 3221 of the second drive coil 322 to generate a first driving force along the Z-axis direction. The second sub-magnetic component 542 of the second group of magnetic components 54 can cooperate with the second sub-coil 3222 of the second drive coil 322 to generate a second driving force along the Z-axis direction. The direction of the first driving force is opposite to the direction of the second driving force, so that the second bracket 52 can drive the first bracket 51 to rotate relative to the base 10 around the second axis R2, that is, the second bracket 52 can drive the first bracket 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, thereby achieving anti-shake.

[0258] It can be understood that in this embodiment, the second group of magnetic parts 54 of the mover 50 is fixed on the second bracket 52, so that the driving force generated by the cooperation of the second group of magnetic parts 54 and the second driving coil 322 can directly act on the second bracket 52, and will not be affected by errors such as assembly between the first bracket 51 and the second bracket 52, which is beneficial to improving the anti-shake accuracy of the drive motor 1a.

[0259] The third embodiment has the same technical contents as the first embodiment and is not further described. FIG49 is a schematic diagram of the cross-sectional structure of the mover 50 shown in FIG20 taken along F1-F1 in the third embodiment. FIG50 is a schematic diagram of the cross-sectional structure of the mover 50 shown in FIG20 taken along F2-F2 in the third embodiment.

[0260] As shown in Figures 49 and 50, the number of first ball bearings 551 in this embodiment can be one. The first connecting portion 515 of the first bracket 51 can be rotatably connected to the first portion 521 of the second bracket 52 via the first ball bearings 551. For example, the first ball bearings 551 can be fixed within the first guide groove 5214 of the first portion 521. A portion of the first ball bearings 551 can be located within the first sliding groove 5152 of the first connecting portion 515.

[0261] Exemplarily, the mover 50 may further include a first magnetic member 5191 and a second magnetic member 5192. The first magnetic member 5191 and the second magnetic member 5192 may have the same shape and size. The first magnetic member 5191 and the second magnetic member 5192 may both be fixed to the first connecting portion 515 of the first bracket 51 (for example, the first magnetic member 5191 and the second magnetic member 5192 may both be embedded in the first connecting portion 515). The first magnetic member 5191 and the second magnetic member 5192 may be arranged along the Z-axis direction. The first magnetic member 5191 may be located on a side of the second magnetic member 5192 close to the light exit hole 20b (see FIG. 32 ). The first ball bearing 551 may be located between the first magnetic member 5191 and the second magnetic member 5192, that is, the first sliding groove 5152 may be located between the first magnetic member 5191 and the second magnetic member 5192. The first magnetic member 5191 and the second magnetic member 5192 may be symmetrically arranged about the first ball bearing 551.

[0262] Exemplarily, the mover 50 may further include a second reinforcement 59. The second reinforcement 59 may be a steel sheet. The second reinforcement 59 may have magnetic conductivity, that is, the second reinforcement 59 may constitute a magnetic sheet. The second reinforcement 59 may be embedded in the interior of the second bracket 52 by injection molding or the like. Part of the second reinforcement 59 may be located in the first portion 521 of the second bracket 52. At this time, the second reinforcement 59 may be arranged opposite to the first magnetic member 5191 and opposite to the second magnetic member 5192. The first magnetic member 5191 may generate a first magnetic attraction force with the second reinforcement 59. The second magnetic member 5192 may generate a second magnetic attraction force with the second reinforcement 59. The component of the first magnetic attraction force in the Z-axis direction may be equal to and opposite to the component of the second magnetic attraction force in the Z-axis direction. The component of the first magnetic attraction force in the X-axis direction can cooperate with the component of the second magnetic attraction force in the X-axis direction to provide pre-pressure for the first bracket 51, so that the first ball 551 can maintain contact with the first connecting portion 515 of the first bracket 51 and the first portion 521 of the second bracket 52.

[0263] For example, the number of second ball bearings 552 may be one. The second connecting portion 516 of the first bracket 51 may be slidably connected to the second portion 522 of the second bracket 52 via a single second ball bearing 552. The mover 50 may further include a third magnetic member 5193 and a fourth magnetic member 5194. The configuration of the third magnetic member 5193 and the fourth magnetic member 5194 may refer to the configuration of the first magnetic member 5191 and the second magnetic member 5192, and will not be further described here.

[0264] The fourth embodiment has the same technical contents as the first embodiment and will not be described in detail: Figure 51 is a schematic structural diagram of the mover 50 shown in Figure 20 in the fourth embodiment. Figure 52 is a schematic cross-sectional structural diagram of the mover 50 shown in Figure 20 taken along F2-F2 in the fourth embodiment.

[0265] As shown in Figures 51 and 52, the number of first balls 551 in this embodiment can be one. The first balls 551 can be fixed to the first connecting portion 515 of the first bracket 51 by welding or other means. The mover 50 can also include a first upper elastic member 5195 and a first lower elastic member 5196. Both the first upper elastic member 5195 and the first lower elastic member 5196 can be leaf springs. The first upper elastic member 5195 can be connected between the first end 5211 of the first portion 521 of the second bracket 52 and the first connecting portion 515 of the first bracket 51. The first lower elastic member 5196 can be connected between the second end 5213 of the first portion 521 of the second bracket 52 and the first connecting portion 515 of the first bracket 51. In this case, the first connecting portion 515 and the first balls 551 can both be located between the first upper elastic member 5195 and the first lower elastic member 5196. Under the action of the first upper elastic member 5195 and the first lower elastic member 5196, the first rolling ball 551 can maintain contact with the wall surface of the first space 521a of the first portion 521, that is, maintain contact with the first portion 521. For example, the rigidity of the first upper elastic member 5195 can be greater than the rigidity of the first lower elastic member 5196. In this way, the first upper elastic member 5195 can overcome the influence of the gravity of the first bracket 51 and maintain the central position of the first rolling ball 551.

[0266] By way of example, the number of second balls 552 may also be one. The second ball 552 may be fixed to the second connecting portion 516 of the first bracket 51 by welding or other means. The mover 50 may also include a second upper elastic member 5197 and a second lower elastic member 5198. The configuration of the second upper elastic member 5197 and the second lower elastic member 5198 may refer to the configuration of the first upper elastic member 5195 and the first lower elastic member 5196 and will not be further described here. In this case, under the action of the second upper elastic member 5197 and the second lower elastic member 5198, the second ball 552 may maintain contact with the wall surface of the second space 522a of the second portion 522, that is, maintain contact with the second portion 522 of the second bracket 52. The straight line connecting the center of the first ball 551 and the center of the second ball 552 may coincide with the first axis R1. By way of example, the stiffness of the second upper elastic member 5197 may be greater than the stiffness of the second lower elastic member 5198. In this way, the second upper elastic member 5197 can overcome the influence of the gravity of the first bracket 51 and maintain the central setting of the second ball 552.

[0267] In the fifth embodiment, the technical contents identical to those in the first embodiment are not further described: FIG53 is a schematic structural diagram of the mover 50 shown in FIG20 in the fifth embodiment. FIG54 is a schematic cross-sectional structural diagram of the mover 50 shown in FIG20 taken along line F1-F1 in the fifth embodiment. FIG55 is a schematic cross-sectional structural diagram of the mover 50 shown in FIG20 taken along line F2-F2 in the fifth embodiment.

[0268] As shown in Figures 53 to 55 , in this embodiment, the number of first balls 551 can be one. The first ball 551 can be fixed within the first guide groove 5214 of the first portion 521 of the second bracket 52. The first connecting portion 515 of the first bracket 51 can be rotatably connected to the first portion 521 of the second bracket 52 via the first ball 551. In this case, the first ball 551 can form point contact with the wall of the first sliding groove 5152 of the first connecting portion 515. The number of second balls 552 can also be one. The second ball 552 can be fixed within the second guide groove 5224 of the second portion 522 of the second bracket 52. The second connecting portion 516 of the first bracket 51 can be rotatably connected to the second portion 522 of the second bracket 52 via the second ball 552. In this case, the second ball 552 can form point contact with the wall of the second sliding groove 5162 of the second connecting portion 516. The line connecting the contact point of the first ball 551 and the contact point of the second ball 552 with the first bracket 51 can coincide with the first axis R1. In this way, when the first bracket 51 rotates around the first axis R1 relative to the second bracket 52, the first ball 551 and the first bracket 51 are in point contact, forming rolling friction, and the second ball 552 and the first bracket 51 are also in point contact, forming rolling friction, thereby effectively reducing the friction between the first ball 551 and the second ball 552 and the first bracket 51 respectively, which is conducive to improving the smoothness of the rotation of the first bracket 51 relative to the second bracket 52.

[0269] In some embodiments, as shown in Figure 56, the first ball 551 can also be fixed in the first sliding groove 5152 of the first connecting portion 515. The first sliding groove 5152 can be a "V"-shaped groove. The first guide groove 5214 can also be a "V"-shaped groove. At this time, there are two contact points between the first ball 551 and the groove wall of the first guide groove 5214, which can form sliding friction. The center of the first ball 551 is located on the first axis R1 of the mover 50. In some other embodiments, the first ball 551 can also be fixed in the first guide groove 5214 by bonding, welding, etc. At this time, there are two contact points between the first ball 551 and the groove wall of the first sliding groove 5152, which can form sliding friction.
