Description

A periscope camera module and electronic device

[0001] This application claims priority to Chinese patent application filed on January 27, 2025, with application number 202510128164.0 and entitled "A periscope camera module and electronic device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of image communication technology, and in particular to a periscope camera module and electronic device. Background Technology

[0003] In mobile devices, such as smartphones and tablets, zoom capabilities are often achieved by using multiple lenses with different focal lengths. For example, a single smartphone can incorporate multiple camera modules to meet both wide-angle and telephoto shooting needs. To extend the telephoto shooting range, the length of the camera module responsible for telephoto shooting along the optical axis of the lens needs to be increased, leading to a thicker mobile device – a contradiction with the need for a slimmer and lighter design. To address this, periscope camera modules have been developed. Periscope camera modules shorten the thickness of the device by folding the optical axis. However, because incident light undergoes multiple refractions within the periscope camera module, its imaging structure is more complex, and it occupies more space, significantly increasing the difficulty of implementing optical image stabilization within a limited space.

[0004] Therefore, how to efficiently achieve optical image stabilization for periscope camera modules is a problem that urgently needs to be solved by technical personnel. Summary of the Invention

[0005] This application provides a periscope camera module and an electronic device, the main purpose of which is to efficiently achieve optical image stabilization of the periscope camera module.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, embodiments of this application provide a periscope camera module, which includes a first lens group, a second lens group, a light steering element, an image sensor, a focusing device, and an optical image stabilization device. The first lens group is located on one side of the second lens group along the optical axis. The light steering element is configured to change the direction of incident light, allowing the incident light to pass through the first and second lens groups. The first and second lens groups are located between the light steering element and the image sensor, and the image sensor is configured to receive the incident light passing through the first and second lens groups. The focusing device is configured to control the first lens group to move along the optical axis of the first lens group. The optical image stabilization device is configured to control the second lens group to move along a first direction. The first direction intersects the optical axis of the second lens group.

[0008] The periscope camera module provided in some embodiments of the first aspect utilizes a light-directing element to fold the optical axis and an image sensor to achieve optical imaging. The focusing device achieves focusing of the periscope camera module by controlling the movement of the first lens group, and the optical image stabilization device achieves image stabilization by controlling the movement of the second lens group. Thus, focusing and image stabilization of the periscope camera module are achieved by different lens groups, which helps reduce the design complexity of the actuators (including the focusing device and the optical image stabilization device) in the periscope camera module and reduces the space occupied by the actuators. Since the focusing device and the optical image stabilization device move the first and second lens groups respectively, it is possible to place the focusing device on one side of the first lens group and the optical image stabilization device on the other side of the second lens group. For example, a front lens can be placed on the side of the light-directing element, thereby making greater use of the optical path space and achieving a longer imaging focal length with a smaller spatial size, thus balancing the small size and focusing distance of the periscope camera module. Furthermore, since image stabilization of a periscope camera module does not require the participation of an optical steering component, the embodiments of this application can effectively improve or avoid image rotation in the imaging of the periscope camera module. Also, since image stabilization of a periscope camera module does not require the participation of an image sensor, and the image sensor does not need to move, the embodiments of this application can further simplify the power supply architecture of the optical image stabilization device and reduce the manufacturing cost of the periscope camera module. Therefore, the embodiments of this application can efficiently achieve optical image stabilization of a periscope camera module.

[0009] In conjunction with the first aspect, in one possible implementation, the optical image stabilization device includes a first structural member and a second structural member. A second lens group is connected to the first structural member, which is configured to move along a first direction. The first structural member has a first guide structure, and the second structural member has a second guide structure. The first guide structure and the second guide structure are coupled together, and the first guide structure is movable along the first direction. In this implementation, the coupling connection between the first and second structural members is achieved through the guide structures (including the first and second guide structures) in the first and second structural members, thereby restricting the first guide structure to be movable along the first direction.

[0010] In conjunction with the first aspect, in one possible implementation, the optical image stabilization device is further configured to control the movement of the second lens group along a second direction. The second direction intersects the first direction and the optical axis direction of the second lens group. The periscope camera module also includes a base component. The second structural component has a third guide structure, and the base component has a fourth guide structure. The third guide structure and the fourth guide structure are coupled together and are movable along the second direction. The second structural component is configured to be movable along the second direction. In this implementation, the coupling connection between the second structural component and the base component is achieved through the guide structures (including the third and fourth guide structures) in the second structural component and the base component, thereby restricting the second guide structure to be movable along the second direction. If the first structural component and the second structural component are coupled together, both the first structural component and the second guide structure are movable along the second direction.

[0011] In conjunction with the first aspect, in one possible implementation, the optical image stabilization device further includes a first magnet and a second magnet. The first magnet is connected to a second structural member. The second magnet is connected to a base member. The first magnet or the second magnet includes a first coil. When the first coil is energized, there is a magnetic force between the first magnet and the second magnet, which is used to control the movement of the second structural member along a second direction. In this implementation, the first magnet and the second magnet are connected to the second structural member and the base member, respectively. When the first coil is energized, the movement of the second structural member is controlled by the magnetic force between the first coil and the magnet (first magnet or second magnet). Since the current in the first coil can change direction, it can also control the movement of the second structural member in the opposite direction of the second direction, achieving reciprocating movement of the second structural member parallel to the second direction. If the first structural member and the second structural member are coupled together, both the first structural member and the second guiding structure can move parallel to the second direction.

[0012] In conjunction with the first aspect, in one possible implementation, the optical image stabilization device further includes a third magnet and a fourth magnet. The third magnet is connected to the first structural member. The fourth magnet is connected to the second structural member. The third or fourth magnet includes a second coil. When the second coil is energized, there is a magnetic force between the third and fourth magnets, which is used to control the movement of the first structural member along a first direction. In this implementation, the third and fourth magnets are connected to the first and second structural members respectively. When the second coil is energized, the movement of the first structural member is controlled by the magnetic force between the second coil and the magnet (the third or fourth magnet). Since the current in the second coil can change direction, it is also possible to control the movement of the first structural member in the opposite direction to the first direction, thereby achieving reciprocating movement of the first structural member parallel to the first direction. If the first structural member can also move along the second direction, then the first structural member can move along the plane containing the first and second directions. The second lens group is connected to the first structural member, so that the second lens group can move along the plane containing the first and second directions. This plane intersects with the optical axis direction of the second lens group, thereby enabling the optical image stabilization of the periscope camera module to be achieved by utilizing the image stabilization of the second lens group.

[0013] In conjunction with the first aspect, in one possible implementation, the first direction intersects with the direction in which incident light enters the light-directing component. The first and second magnets are located on the side of the second lens group facing the first direction, while the third and fourth magnets are located on the side of the second lens group facing away from the first direction. In this implementation, the first direction intersects with the direction in which incident light enters the light-directing component. Positioning the magnets on opposite sides of the second lens group along the first direction ensures the driving effect of the magnets on the structural components (including the first and second structural components) while minimizing the size of the optical image stabilization device along the direction in which incident light enters the light-directing component, thereby reducing the size of the periscope camera module along this direction. Since the periscope camera module is typically used in electronic devices where the direction in which incident light enters the light-directing component is usually the thickness direction of the electronic device, this implementation can reduce the size of the periscope camera module along the thickness direction of the electronic device, thus contributing to the thinning and lightening of electronic devices.

[0014] In conjunction with the first aspect, in one possible implementation, the number of any one of the first magnet, second magnet, third magnet, and fourth magnet is one or more. In this implementation, by appropriately setting the number of each magnet, it is possible to ensure both the lightweight nature of the optical image stabilization device and to provide sufficient driving force for the first or second structural component in the optical image stabilization device.

[0015] In conjunction with the first aspect, in one possible implementation, the optical image stabilization device further includes a fifth magnet and a sixth magnet. The fifth magnet is connected to the first structural member, and the sixth magnet is connected to the second structural member. There is a magnetic attraction between the fifth and sixth magnets. In this implementation, the magnetic attraction between the magnets enables the magnetic connection between the first and second structural members.

[0016] In conjunction with the first aspect, in one possible implementation, the optical image stabilization device further includes a seventh magnet and an eighth magnet. The seventh magnet is connected to the second structural member, and the eighth magnet is connected to the base member. There is a magnetic attraction between the seventh and eighth magnets. In this implementation, the magnetic attraction between the magnets enables a magnetic connection between the second structural member and the base member.

[0017] In conjunction with the first aspect, in one possible implementation, the first guiding structure includes a first sub-part, a second sub-part, and a third sub-part, which are respectively coupled to the second guiding structure. Therefore, the number of first guiding structures between the first and second structural components can be set according to actual needs, utilizing three or more distributed coupling points to improve the stability of the coupling connection between the first and second structural components.

[0018] In conjunction with the first aspect, in one possible implementation, the third guiding structure includes a fourth sub-section, a fifth sub-section, and a sixth sub-section, which are respectively coupled to the fourth guiding structure. Therefore, the number of contact points between the second structural component and the base component can be set according to actual needs, utilizing three or more distributed coupling points to improve the stability of the coupling connection between the second structural component and the base component.

[0019] In conjunction with the first aspect, in one possible implementation, the optical image stabilization device further includes a first ball bearing located between the first guide structure and the second guide structure. And / or, the optical image stabilization device further includes a second ball bearing located between the third guide structure and the fourth guide structure. In this implementation, the ball bearing can be used to reduce the friction between the first and second guide structures, and also to reduce the friction between the third and fourth guide structures. This reduces the driving force used to drive the guide structures, thereby reducing the space and energy consumption of the driving components (such as the first and second magnets, the third magnet, and the fourth magnet). It also reduces the heat generated by friction in the optical image stabilization device, thus reducing the heat generation of the periscope camera module, and helps reduce frictional losses between structural components, extending the lifespan of the optical image stabilization device.

[0020] In conjunction with the first aspect, in one possible implementation, the periscope camera module further includes a base. The base has a first receiving space and a second receiving space. A light-guiding element is disposed within the first receiving space, and a second lens group and an optical image stabilization device are disposed within the second receiving space. The first receiving space has a first opening, and the second receiving space has a second opening. The first and second openings are oriented in opposite directions, and the first opening is oriented in the opposite direction to the direction in which incident light enters the light-guiding element. In this implementation, the opposite openings of the receiving spaces for the light-guiding element and the second lens group within the base facilitate reverse assembly of the light-guiding element and the lens group. The opposite openings of the receiving spaces for the light-guiding element and the optical image stabilization device within the base also facilitate reverse assembly of the light-guiding element and the optical image stabilization device. Since the side of the light-guiding component facing the first opening is the light-inlet side, other optical components are often required on this side, such as a front-facing lens. If the second opening is opposite in direction to the first opening, and the second lens group and optical image stabilization device are installed into the second receiving space through the second opening, the structure in the base for assembling with the second lens group and optical image stabilization device can be located on the light-inlet side of the periscope camera module. This allows it to be on the same side as the optical components on the light-inlet side of the light-guiding component, thus making better use of the space along the incident light entry direction of the periscope camera module. This effectively reduces the size of the periscope camera module along the direction of incident light entering the light-guiding component. Furthermore, if the periscope camera module is applied to electronic devices, the direction of incident light entering the light-guiding component is usually the thickness direction of the electronic device. Therefore, this implementation can reduce the size of the periscope camera module along the thickness direction of the electronic device, thus contributing to the thinning and lightening of electronic devices.

[0021] Secondly, embodiments of this application provide an electronic device, which includes the periscope camera module in any of the above embodiments.

[0035] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0036] In the description of the embodiments of this application, unless otherwise stated, "a plurality of" means two or more.

[0037] Furthermore, to facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that "first" and "second" are not necessarily different. Meanwhile, in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate that something is being used as an example, illustration, or description. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner for ease of understanding.

[0038] In describing some embodiments, the term "connection" and its derivative expressions are used. The term "connection" should be interpreted broadly; for example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0039] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0040] In the accompanying drawings, the thickness of some layers or regions has been selectively exaggerated for clarity, and the dimensional proportions between the portions shown do not reflect actual dimensional proportions. Therefore, variations in shape relative to the drawings are conceivable due to factors such as manufacturing techniques and / or tolerances. Consequently, exemplary embodiments should not be construed as limited to the shapes of the regions shown in this application, but rather include shape deviations caused, for example, by manufacturing processes. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the regions of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0041] Figure 1 is a structural diagram of an electronic device 1000 provided in an embodiment of this application.

[0042] This application provides an electronic device 1000, as shown in FIG1. ​​The electronic device 1000 includes a periscope camera module 100.

[0043] Taking a mobile phone as an example, the periscope camera module 100 can be set on the front or back of the mobile phone, and the direction of incident light entering the periscope camera module 100 can be the same as the thickness direction of the electronic device 1000.

[0044] In some examples, as shown in Figure 1, the electronic device 1000 may include multiple camera modules. The periscope camera module 100 may also be used in conjunction with other camera modules, with the periscope camera module 100 fixing the telephoto lens for shooting, and the other camera modules handling other focal lengths.

[0045] The aforementioned electronic devices 1000 include, but are not limited to, electronic devices 1000 in the fields of information technology (IT) and communication technology (CT), and can be applied to various scenarios. These electronic devices 1000 include, for example, consumer products, home products, automotive products, wearable products, financial terminal products, and communication products. For example, the electronic device 1000 may include, but is not limited to, mobile phones, tablets, smart wearable products (e.g., smartwatches, smart bracelets), handheld game consoles, smart TVs, routers, headphones, microphones, extended reality (XR) devices, inertial navigation systems, supplemental inflatable restraint systems (SRS) devices, smart door locks, stethoscopes, helmets, controllers, and fluid pressure gauges. The aforementioned XR devices include, for example, virtual reality (VR) devices, augmented reality (AR) devices, mixed reality (MR) devices, and robots.

[0046] Figure 2 is an optical path structure diagram of a periscope camera module 100 provided in an embodiment of this application.

[0047] The related technology provides a periscope camera module 100, as shown in Figure 2. The periscope camera module 100 includes a light steering element 1, a lens group 2, and an image sensor 3. As shown in Figure 2, R1 is the optical path direction of incident light entering the periscope camera module 100 or the light steering element 1, and R2 is the optical path direction of incident light passing through the lens group 2.

[0048] As shown in Figure 2, in order to ensure the imaging quality of the periscope camera module 100, image stabilization is required for electronic devices 1000, such as mobile phones. Image stabilization of the periscope camera module 100 can be achieved by any one of the moving optical steering element 1, lens group 2, and image sensor 3.

[0049] However, in the periscope camera module 100, if the optical stabilization is performed by moving the light steering component 1, the image of the periscope camera module 100 is prone to image rotation, which deteriorates the imaging effect of the periscope camera module 100.

[0050] If the moving lens group 2 is used for optical image stabilization, since the focusing of the periscope camera module 100 usually also requires the moving lens group 2, it will not only increase the design and manufacturing difficulty of the optical image stabilization device 5 and the focusing device 4, but also cause the actuators, including the optical image stabilization device 5 and the focusing device 4, to occupy too much space, thereby increasing the size of the periscope camera module 100, which is not conducive to the thinning and lightening of the electronic device 1000.

[0051] If optical image stabilization is implemented using a movable image sensor 3, a complex power supply architecture needs to be constructed for the sensor 3 to allow movement. For example, to enable movement of the image sensor 3, both upright and horizontal orientations increase the height of the rear of the periscope camera module 100. Alternatively, tilting the image sensor 3 using a Schmidt prism to achieve movement would increase the overall length of the module. Therefore, these solutions not only increase the design and manufacturing complexity of the periscope camera module 100 but also significantly increase its manufacturing cost.

[0052] Therefore, the above-mentioned embodiments for achieving optical image stabilization of the periscope camera module 100 all have some drawbacks. How to efficiently achieve optical image stabilization of the periscope camera module 100 is a problem that urgently needs to be solved by technical personnel.

[0053] Figure 3 is an optical path structure diagram of another periscope camera module 100 provided in an embodiment of this application.

[0054] In view of this, this application provides a periscope camera module 100, as shown in FIG3. The periscope camera module 100 includes a first lens group 21, a second lens group 22, a light steering component 1, and an image sensor 3.

[0055] As shown in Figure 3, the optical path structure of the periscope camera module 100 is shown from the direction intersecting with the direction in which the incident light enters the optical deflector 1.

[0056] In some examples, the first lens group 21 may include one or more lenses, and the second lens group 22 may include one or more lenses.

[0057] In some examples, the light deflector 1 can be a prism. For example, the light deflector 1 can be a reflecting prism or a refracting prism.

[0058] In this embodiment, the second lens group 22 is located on one side of the second lens group 22 along the optical axis, and the first lens group 21 and the second lens group 22 are located between the light steering member 1 and the image sensor 3.

[0059] In some examples, the first lens group 21 may be located between the light steering element 1 and the second lens group 22, and the second lens group 22 may be located between the first lens group 21 and the image sensor 3.

[0060] In some other examples, as shown in Figure 3, the first lens group 21 may be located between the second lens group 22 and the image sensor 3, and the second lens group 22 may be located between the light steering element 1 and the first lens group 21.

[0061] In this embodiment, the light steering element 1 is configured to change the direction of the incident light so that the incident light passes through the first lens group 21 and the second lens group 22.

[0062] For example, the light deflector 1 includes a prism, which can change the preset angle after the incident light is reflected and / or refracted by the prism. For example, the preset angle can be 90°.

[0063] In some optional embodiments, the direction in which the incident light enters the light-directing member 1 may intersect with the optical axis direction of the first lens group 21 or the second lens group 22. For example, the direction in which the incident light enters the light-directing member 1 may be perpendicular to the optical axis direction of the first lens group 21 or the second lens group 22.

[0064] For example, the optical axis direction of the first lens group 21 and the optical axis direction of the second lens group 22 can be the same.

[0065] In this embodiment, the image sensor 3 is configured to receive incident light passing through the first lens group 21 and the second lens group 22.

[0066] In some examples, incident light can pass sequentially through light deflector 1, first lens group 21, and second lens group 22 to reach image sensor 3.

[0067] In some other examples, as shown in Figure 3, the incident light can pass sequentially through the light deflector 1, the second lens group 22, and the first lens group 21 to reach the image sensor 3.

[0068] For example, the image sensor 3 can be a complementary metal-oxide-semiconductor (CMOS) sensor. For instance, the photosensitive size of the image sensor 3 can be greater than or equal to 1 / 2 inch.

[0069] In the periscope camera module 100, the number and position of the image sensors can be flexibly configured according to requirements. For example, the imaging system of the periscope camera module 100 may include a single image sensor perpendicular to the optical axis, a single image sensor placed horizontally with the aid of a prism, or multiple image sensors arranged by beam splitting. This application embodiment does not impose any limitations on this.

[0070] Figure 4 is an optical path structure diagram of the periscope camera module 100 provided in the embodiment shown in Figure 3 from another perspective.

[0071] As shown in Figure 4, the optical path structure of the periscope camera module 100 is shown from the opposite direction of the direction in which the incident light enters the light-directing component 1.

[0072] Figure 5 is a structural diagram of the periscope camera module 100 provided in the embodiment shown in Figure 4. Figure 6 is an exploded view of the periscope camera module provided in the embodiment shown in Figure 5 from a first-view perspective.

[0073] As shown in Figures 5 and 6, in this embodiment of the application, the periscope camera module 100 further includes a focusing device 4 and an optical image stabilization device 5.

[0074] In this embodiment of the application, as shown in FIG5, the focusing device 4 is configured to control the first lens group 21 to move along the optical axis direction of the first lens group 21.

[0075] In some examples, as shown in Figure 5, the optical axis direction of the first lens group 21 can be the X direction, and the focusing device 4 can control the first lens group 21 to move along the X direction.

[0076] In this embodiment, the optical image stabilization device 5 is configured to control the second lens group 22 to move along a first direction. The first direction intersects the optical axis direction of the second lens group 22.

[0077] In some examples, the first direction and the optical axis direction of the second lens group 22 can be perpendicular to each other.

[0078] For example, as shown in Figure 4, the first direction can be parallel to the Y direction or the Z direction, and the optical image stabilization device 5 can control the second lens group 22 to move along the Y direction or the Z direction.

[0079] Through the above embodiments, the periscope camera module 100 utilizes the light-directing component 1 to fold the optical axis and uses the image sensor 3 to achieve optical imaging. The focusing device 4 controls the movement of the first lens group 21 to achieve focusing of the periscope camera module 100, and the optical image stabilization device 5 controls the movement of the second lens group 22 to achieve image stabilization. Thus, focusing and image stabilization of the periscope camera module 100 are achieved by different lens groups 2, which helps reduce the design difficulty of the actuators in the periscope camera module 100 and reduces the space occupied by the actuators. Since the focusing device 4 and the optical image stabilization device 5 move the first lens group 21 and the second lens group 22 respectively, it is helpful to place the focusing device 4 on one side of the first lens group 21 and the optical image stabilization device 5 on the other side of the second lens group 22. For example, a front lens can also be placed on the side of the light-directing component 1, thereby making greater use of the optical path space of the periscope camera module 100 and achieving a longer imaging focal length with a smaller space size. Furthermore, since the image stabilization of the periscope camera module 100 does not require the participation of the optical steering component 1, the embodiments of this application can effectively improve or avoid image rotation in the imaging of the periscope camera module 100. Also, since the image stabilization of the periscope camera module 100 does not require the participation of the image sensor 3, and the image sensor 3 does not need to move, the embodiments of this application can further simplify the power supply architecture of the optical image stabilization device 5 and reduce the manufacturing cost of the periscope camera module 100. Therefore, the embodiments of this application can efficiently achieve optical image stabilization of the periscope camera module 100.

[0080] In some alternative embodiments, as shown in FIG5, the first direction intersects the direction in which the incident light enters the light-directing member 1, and at least a portion of the structure in the focusing device 4 may be located on one side or opposite sides of the first lens group 21 along the first direction.

[0081] For example, the drive unit in the focusing device 4 may be located on one side or opposite sides of the first lens group 21 along the first direction.

[0082] For example, the driving component in the focusing device 4 may include, but is not limited to, any one of a voice coil motor, a piezoelectric motor, or an SMA motor.

[0083] Through the above embodiments, the focusing device 4 can be positioned as far away as possible from the direction in which the incident light enters the light-directing member 1 along the first lens group 21, thereby helping to reduce the size of the periscope camera module 100 and the electronic device 1000 along the thickness direction of the electronic device 1000, which is of positive significance for realizing the thinning and lightening of the electronic device 1000.

[0084] In some alternative embodiments, the size of the focusing device 4 is larger than the size of the first lens group 21 along the optical axis direction of the first lens group 21.

[0085] For example, along the optical axis of the first lens group 21, the ratio between the size of the focusing device 4 and the size of the first lens group 21 may include, but is not limited to, 1.1, 1.2, 1.3, 1.4, and 1.5.

[0086] Through the above embodiments, some structural components of the focusing device 4 can also be arranged in the optical path space of the first lens group 21, thereby effectively utilizing the optical path space between the light steering component 1 and the image sensor 3, achieving a longer imaging focal length with a smaller spatial size, thus taking into account the small size and focusing distance of the periscope camera module 100.

[0087] In some alternative embodiments, as shown in FIG6, the optical image stabilization device 5 includes a first structural member 51 and a second structural member 52.

[0088] In this embodiment of the application, as shown in FIG6, the second lens group 22 is connected to the first structural member 51, and the first structural member 51 is configured to be movable along a first direction.

[0089] In some optional embodiments, as shown in FIG6, the first structural member 51 has a first guide structure 511, the second structural member 52 has a second guide structure 521, the first guide structure 511 and the second guide structure 521 are coupled together, and the first guide structure 511 is movable along a first direction.

[0090] In some examples, the first guide structure 511 and the second guide structure 521 can be coupled together via a sliding shaft. Exemplarily, the first guide structure 511 may have a groove extending along a first direction, and the second guide structure 521 may include a slider extending into the first groove and capable of contacting the bottom of the groove. For example, the groove may be a UV groove, and the surface of the slider contacting the bottom of the groove may be curved, thereby reducing the friction between the first guide structure 511 and the second guide structure 521.

[0091] For example, as shown in Figure 6, the first guide structure 511 may include a slider, and the second guide structure 521 may have a groove.

[0092] In some other examples, the first guide structure 511 and the second guide structure 521 can also be coupled together by means of balls or rollers, which can further reduce the friction between the first guide structure 511 and the second guide structure 521.

[0093] Through the above embodiments, the first structural member 51 and the second structural member 52 are coupled together by the guide structures in the first structural member 51 and the second structural member 52, thereby enabling the first guide structure 511 to be restricted to move along the first direction.

[0094] In some alternative embodiments, the optical image stabilization device 5 is also configured to control the movement of the second lens group 22 along a second direction. The second direction intersects the first direction and the optical axis direction of the second lens group 22.

[0095] For example, the second direction may be perpendicular to the first direction and perpendicular to the optical axis direction of the second lens group 22.

[0096] For example, as shown in Figure 6, the optical axis of the second lens group 22 is in the X direction, the first direction can be the Y direction, and the second direction can be the Z direction.

[0097] Figure 7 is an exploded view of another structure of the periscope camera module provided in the embodiment shown in Figure 5 from a first-view perspective.

[0098] In this embodiment of the application, as shown in FIG7, the periscope camera module 100 further includes a base 6, which has a fourth guide structure 61.

[0099] Figure 8 is a structural diagram from a second perspective of the embodiment shown in Figure 5. For ease of illustration, the entire structure is not shown in Figure 8 (e.g., the base member 6 in Figure 7 is not shown).

[0100] In some alternative embodiments, as shown in FIG8, the second structural member 52 has a third guide structure 522.

[0101] In this embodiment, the third guide structure 522 shown in FIG8 is coupled to the fourth guide structure 61 shown in FIG7 and is movable along the second direction. The second structural member 52 is configured to be movable along the second direction.

[0102] In some examples, the coupling connection between the third guide structure 522 and the fourth guide structure 61 can be referenced to the coupling connection between the first guide structure 511 and the second guide structure 521, and will not be described again here.

[0103] Through the above embodiments, the second structural member 52 and the base member 6 are coupled together via the guide structure in the second structural member 52 and the base member 6, thereby enabling the second guide structure 521 to be restricted to move along the second direction. If the first structural member 51 is coupled together with the second structural member 52, both the first structural member 51 and the second guide structure 521 can move along the second direction.

[0104] Therefore, this embodiment utilizes the coupling connection between the first structural member 51 and the second structural member 52, and the coupling connection between the second structural member 52 and the base member 6, to control the movement of the first structural member 51 and the second structural member 52 respectively, thereby controlling the movement of the second lens group 22 in two directions. This achieves decoupling of the image stabilization movement control of the second lens group 22, reducing the design and manufacturing difficulty of the periscope camera module 100, lowering the manufacturing cost of the periscope camera module 100, and also helping to reduce the size of the periscope camera module 100, thereby achieving a thinner and lighter electronic device 1000. For example, if the periscope camera module 100 is applied to the electronic device 1000, the dimension of the periscope camera module 100 along the thickness direction of the electronic device 1000 can not exceed 9.3mm.

[0105] In some optional embodiments, as shown in FIG8, the third guide structure 522 includes a fourth sub-part 5221, a fifth sub-part 5222 and a sixth sub-part 5223, which are respectively coupled to the fourth guide structure 61 in FIG6.

[0106] Therefore, the number of contact positions between the second structural component 52 and the base component 6 can be set according to actual needs, and the stability of the coupling connection between the second structural component 52 and the base component 6 can be improved by using three or more distributed coupling positions.

[0107] In some examples, as shown in FIG8, the fourth sub-part 5221 and the fifth sub-part 5222 may be located on the side of the second lens group 22 facing the second direction, and the sixth sub-part 5223 may be located on the side of the second lens group 22 facing away from the second direction. Exemplarily, the second direction may intersect with the direction in which the incident light enters the light-directing member 1, and may also intersect with the optical axis direction of the second lens group 22. For example, the second direction may be the Y direction.

[0108] For example, the number of sub-parts provided in the fourth guide structure 61 can be the same as the number of sub-parts provided in the third guide structure 522. For instance, the sub-parts in the third guide structure 522 can be three sliders, and the sub-parts provided in the fourth guide structure 61 can be three UV grooves.

[0109] In some alternative embodiments, the number of sub-parts in the third guide structure 522 may also be other, such as one, two or four.

[0110] In some optional embodiments, the first guide structure 511 includes a first sub-part, a second sub-part, and a third sub-part, which are respectively coupled to the second guide structure 521. Thus, the number of first guide structures 511 between the first structural member 51 and the second structural member 52 can be set according to actual needs, utilizing three or more distributed coupling points to improve the stability of the coupling connection between the first structural member 51 and the second structural member 52.

[0111] In some examples, the structures of the first, second, and third sub-parts can be set with reference to the fourth sub-part 5221, the fifth sub-part 5222, and the sixth sub-part 5223, and are no longer drawn separately.

[0112] For example, the number of sub-parts provided in the second guide structure 521 may be the same as or different from the number of sub-parts in the first guide structure 511.

[0113] In some alternative embodiments, the number of sub-parts in the first guide structure 511 may also be other, such as one, two or four.

[0114] In some alternative embodiments, as shown in FIG7, the optical image stabilization device 5 further includes a first magnet 541 and a second magnet 542.

[0115] In this embodiment, the first magnet 541 is connected to the second structural member 52. The second magnet 542 is connected to the base member 6. The first magnet 541 or the second magnet 542 includes a first coil 5401. When the first coil 5401 is energized, there is a magnetic force between the first magnet 541 and the second magnet 542, which is used to control the movement of the second structural member 52 along a second direction.

[0116] In some examples, the second magnet 542 includes a first coil 5401, and the first magnet 541 can be a permanent magnet. For example, as shown in Figure 7, the first magnet 541 includes a first coil 5401, and the second magnet 542 can be a permanent magnet.

[0117] For example, the long side of the first coil 5401 may intersect with the first direction and may intersect with the optical axis of the second lens group 22, and the short side of the first coil 5401 may be parallel to the optical axis of the second lens group 22.

[0118] For example, the magnetic pole direction of the permanent magnet can be parallel to the long side direction of the first coil 5401.

[0119] For example, the types of permanent magnets include, but are not limited to, neodymium iron boron magnets, cobalt boron magnets, and ferrite magnets.

[0120] In the above embodiments, the first magnet 541 and the second magnet 542 are respectively connected to the second structural member 52 and the base member 6. When the first coil 5401 is energized, the magnetic force between the first coil 5401 and the magnets controls the movement of the second structural member 52. Since the current in the first coil 5401 can change direction, it can also control the second structural member 52 to move in the opposite direction of the second direction, realizing the reciprocating movement of the second structural member 52 parallel to the second direction. If the first structural member 51 and the second structural member 52 are coupled together, both the first structural member 51 and the second guide structure 521 can move parallel to the second direction.

[0121] In some optional embodiments, the optical image stabilization device 5 may include one or more first magnets 541, and the optical image stabilization device 5 may also include one or more second magnets 542.

[0122] For example, as shown in Figure 7, the optical image stabilization device 5 includes three first magnets 541 and one second magnet 542.

[0123] Therefore, by appropriately setting the number of the first magnet 541 and the second magnet 542 according to the driving force required by the second structural member 52 and the available space in the periscope camera module 100, it is possible to ensure the lightweight of the optical image stabilization device 5 and provide sufficient driving force for the second structural member 52 in the optical image stabilization device 5.

[0124] In some alternative embodiments, as shown in FIG6, the optical image stabilization device 5 further includes a third magnet 543 and a fourth magnet 544.

[0125] In this embodiment, the third magnet 543 is connected to the first structural member 51. The fourth magnet 544 is connected to the second structural member 52. The third magnet 543 or the fourth magnet 544 includes a second coil 5402. When the second coil 5402 is energized, there is a magnetic force between the third magnet 543 and the fourth magnet 544, which is used to control the first structural member 51 to move along a first direction.

[0126] In some examples, the third magnet 543 includes the second coil 5402, and the fourth magnet 544 can be a permanent magnet. For example, as shown in Figure 6, the fourth magnet 544 includes the second coil 5402, and the third magnet 543 can be a permanent magnet.

[0127] For example, the long side of the second coil 5402 may intersect with the first direction and may also intersect with the optical axis of the second lens group 22, while the short side of the first coil 5401 may be parallel to the first direction.

[0128] For example, the magnetic pole direction of the permanent magnet can be parallel to the long side direction of the second coil 5402.

[0129] In the above embodiments, the third magnet 543 and the fourth magnet 544 are connected to the first structural member 51 and the second structural member 52, respectively. When the second coil 5402 is energized, the magnetic force between the second coil 5402 and the magnets controls the movement of the first structural member 51. Since the current in the second coil 5402 can change direction, it can also control the first structural member 51 to move in the opposite direction of the first direction, realizing the reciprocating movement of the first structural member 51 parallel to the first direction. If the first structural member 51 can also move in the second direction, then the first structural member 51 can move along the plane containing the first and second directions. The second lens group 22 is connected to the first structural member 51, so the second lens group 22 can move along the plane containing the first and second directions. This plane intersects with the optical axis direction of the second lens group 22, thereby enabling the periscope camera module 100 to achieve optical image stabilization by utilizing the image stabilization of the second lens group 22.

[0130] In some alternative embodiments, the optical image stabilization device 5 may include one or more third magnets 543, and the optical image stabilization device 5 may also include one or more fourth magnets 544.

[0131] For example, as shown in Figure 6, the optical image stabilization device 5 includes a third magnet 543 and two fourth magnets 544.

[0132] Therefore, by appropriately setting the number of the third magnet 543 and the fourth magnet 544 according to the driving force required by the first structural component 51 and the available space in the periscope camera module 100, it is possible to ensure the lightweight of the optical image stabilization device 5 and provide sufficient driving force for the first structural component 51 or the second structural component 52 in the optical image stabilization device 5.

[0133] In some alternative embodiments, as shown in FIG6, the first direction intersects with the direction in which the incident light enters the light deflector 1 shown in FIG3. The first magnet 541 and the second magnet 542 are located on the side of the second lens group 22 facing the first direction, and the third magnet 543 and the fourth magnet 544 are located on the side of the second lens group 22 facing away from the first direction.

[0134] For example, the first direction is perpendicular to the direction in which the incident light enters the light deflector 1.

[0135] In the above embodiments, the first direction intersects with the direction in which the incident light enters the light-directing component 1. The first magnet 541 and the second magnet 542 are positioned on one side of the second lens group 22 parallel to the first direction, while the third magnet 543 and the fourth magnet 544 are positioned on the other side of the second lens group 22 parallel to the first direction. This ensures the driving effect of the magnets on the structural components while minimizing the size of the optical image stabilization device 5 along the direction of the incident light entering the light-directing component 1, thereby reducing the size of the periscope camera module 100 along the direction of the incident light entering the light-directing component 1. If the periscope camera module 100 is applied to the electronic device 1000, the direction of the incident light entering the light-directing component 1 is typically the thickness direction of the electronic device 1000. Therefore, the embodiments of this application can reduce the size of the periscope camera module 100 along the thickness direction of the electronic device 1000, thus contributing to the thinning and lightening of the electronic device 1000.

[0136] In some alternative embodiments, as shown in FIG6, the optical image stabilization device 5 further includes a fifth magnet 545 and a sixth magnet 546.

[0137] In this embodiment, the fifth magnet 545 is connected to the first structural member 51, and the sixth magnet 546 is connected to the second structural member 52. There is a magnetic attraction between the fifth magnet 545 and the sixth magnet 546. Therefore, by utilizing the magnetic attraction between the magnets, a magnetic connection between the first structural member 51 and the second structural member 52 can be achieved.

[0138] In some examples, the structural components may include magnet slots for placing magnets. For example, as shown in Figure 6, the second structural component 52 may have a magnet slot for placing a sixth magnet 546.

[0139] In some alternative embodiments, the optical image stabilization device 5 may include one or more fifth magnets 545, and the optical image stabilization device 5 may also include one or more sixth magnets 546. For example, as shown in FIG6, the optical image stabilization device 5 includes a fifth magnet 545 and a sixth magnet 546.

[0140] In some alternative embodiments, as shown in FIG7, the optical image stabilization device 5 further includes an eighth magnet 548. As shown in FIG8, the optical image stabilization device 5 further includes a seventh magnet 547.

[0141] In this embodiment of the application, as shown in FIG7, the eighth magnet 548 is connected to the base member 6. As shown in FIG8, the seventh magnet 547 is connected to the second structural member 52.

[0142] In this embodiment, the seventh magnet 547 and the eighth magnet 548 have a magnetic attraction. Therefore, by utilizing the magnetic attraction between the magnets, a magnetic connection can be achieved between the second structural member 52 and the base member 6.

[0143] In some optional embodiments, the optical image stabilization device 5 may include one or more seventh magnets 547, and the optical image stabilization device 5 may also include one or more eighth magnets 548. For example, the optical image stabilization device 5 may include three seventh magnets 547 and three eighth magnets 548.

[0144] In some alternative embodiments, as shown in FIG7, the periscope camera module 100 may further include a circuit board 71. Exemplarily, the circuit board 71 may be connected to the base 6.

[0145] In some alternative embodiments, circuit board 71 can be a flexible circuit board or a resilient circuit board. Exemplarily, circuit board 71 can be electrically connected to the optical image stabilization device 5 and / or the focusing device 4. For example, circuit board 71 can be electrically connected to the first coil 5401 and / or the second coil 5402 in the optical image stabilization device 5 to provide power, and the resilient or flexible nature of circuit board 71 helps to achieve a movable power supply architecture.

[0146] In some alternative embodiments, as shown in FIG7, the periscope camera module 100 may further include a first Hall sensor 551 and / or a second Hall sensor 552.

[0147] In some examples, as shown in Figure 6, the first Hall sensor 551 can be arranged adjacent to the second coil 5402, and there is a gap between the first Hall sensor 551 and the second coil 5402. Thus, using the first Hall sensor 551, a bidirectional Hall detection circuit can be set up to detect the relative position of the first structural member 51 and the second structural member 52.

[0148] In some other examples, as shown in Figure 7, the second Hall sensor 552 can be arranged adjacent to the first coil 5401, with a gap between the second Hall sensor 552 and the first coil 5401. Thus, using the second Hall sensor 552, a bidirectional Hall detection circuit can be configured to detect the relative position of the second structural member 52 and the base member 6.

[0149] For example, the bidirectional Hall effect detection circuit can also be powered through circuit board 71.

[0150] In some alternative embodiments, as shown in FIG7, the periscope camera module 100 may further include a third lens group 23, which may be connected to the base 6. For example, the third lens group 23 may be fixed relative to the base 6.

[0151] For example, the third lens group 23 may include one or more lenses, and the optical axis direction of the third lens group 23 may be the same as that of the first lens group 21 or the second lens group 22. For example, the third lens group 23 may be disposed between the first lens group 21 and the second lens group 22.

[0152] Figure 9 is a cross-sectional view of the periscope camera module provided in the embodiment shown in Figure 5 along the "AA'" direction. For ease of illustration, Figure 9 does not show the entire structure shown in Figure 4 (e.g., the third magnet 543 and the fourth magnet 544 in Figure 5 are not shown).

[0153] In this embodiment of the application, as shown in FIG9, the base member 6 has a first receiving space 62 and a second receiving space 63. The light steering member 1 is disposed in the first receiving space 62, and the second lens group 22 and the optical image stabilization device 5 are disposed in the second receiving space 63.

[0154] As shown in Figure 9, the first accommodating space 62 has a first opening, and the second accommodating space 63 has a second opening. The first opening and the second opening are oriented in opposite directions, and the orientation of the first opening is opposite to the direction in which the incident light enters the light deflector 1.

[0155] For example, the direction in which the incident light enters the light deflector 1 is opposite to the Z direction, the orientation of the first opening M1 can be the same as the Z direction, and the orientation of the second opening M2 can be opposite to the Z direction.

[0156] In the above embodiments, the openings of the receiving spaces of the light-directing component 1 and the second lens group 22 in the base 6 are opposite, which helps to achieve reverse assembly of the light-directing component 1 and the lens group 2. The openings of the receiving spaces of the light-directing component 1 and the optical image stabilization device 5 in the base 6 are also opposite, which also helps to achieve reverse assembly of the light-directing component 1 and the optical image stabilization device 5. Since the side of the light-directing component 1 facing the first opening is the light-inlet side, other optical devices are often required on the light-inlet side of the light-directing component 1. For example, the optical devices can be front lenses. If the direction of the second opening is opposite to that of the first opening, and the second lens group 22 and the optical image stabilization device 5 are installed into the second receiving space 63 through the second opening, then the structure in the base 6 for assembling with the second lens group 22 and the optical image stabilization device 5 can be set on the light-inlet side of the periscope camera module 100. Thus, the structure in the base 6 for assembling with the second lens group 22 and the optical image stabilization device 5 can be on the same side as the optical devices on the light-inlet side of the light-directing component 1. This allows for greater utilization of the space of the periscope camera module 100 along the direction of incident light entry, thereby effectively reducing the size of the periscope camera module 100 along the direction of incident light entry into the light-directing component 1. If the periscope camera module 100 is applied to the electronic device 1000, the direction in which the incident light enters the light steering member 1 is usually the thickness direction of the electronic device 1000. Therefore, the embodiments of this application can reduce the size of the periscope camera module 100 along the thickness direction of the electronic device 1000, thereby helping to achieve the thinning and lightening of the electronic device 1000.

[0157] In some optional embodiments, as shown in FIG9, the side where the incident light enters the periscope camera module 100 is designated as the first side, and the side of the periscope camera module 100 facing away from the light-entering side is designated as the second side. Along the direction in which the incident light enters the light-directing member 1, the size of the optical image stabilization device 5 on the first side of the second lens group 22 is larger than the size of the optical image stabilization device 5 on the second side of the second lens group 22.

[0158] For example, as shown in Figure 9, the size of the optical image stabilization device 5 located on the Z-direction side of the second lens group 22 is larger than the size of the optical image stabilization device 5 located on the Z-direction side of the second lens group 22.

[0159] Through the above embodiments, by placing a relatively large number of optical image stabilization devices 5 at the light-receiving end of the periscope camera module 100, the optical axis of the second lens group can be better aligned with the light-directing component. The optical image stabilization device 5 can be located on the same side of the light-receiving side of the light-directing component 1 and the second lens group 22, thereby improving the space utilization rate of the periscope camera module 100 along the direction in which incident light enters the light-directing component 1, and further reducing the size of the periscope camera module 100 along the thickness direction of the electronic device 1000.

[0160] In some alternative embodiments, as shown in FIG9, the base 6 may also have a third receiving space 64, in which the first lens group 21 and the focusing device 4 are disposed.

[0161] In some examples, the third receiving space 64 has a third opening, which can be oriented in the same direction as the second opening, so that the first lens group 21, the focusing device 4, the second lens group 22 and the optical image stabilization device 5 can be assembled in the same direction. This can further improve the space utilization rate inside the periscope camera module 100, reduce the size of the periscope camera module 100 entering the light-directing member 1 along the incident light, and ensure the optical axis length, thereby increasing the focusing distance and ensuring the imaging effect at long focal lengths.

[0162] In some optional embodiments, as shown in FIG9, the size of the focusing device 4 on the first side of the first lens group 21 is larger than the size of the focusing device 4 on the second side of the first lens group 21 along the direction in which the incident light enters the light-adjusting element 1. Therefore, the focusing device 4 can be located on the same side as the optical devices on the light-entry side of the light-adjusting element 1, the first lens group 21, and the second lens group 22, further improving the space utilization of the periscope camera module 100 along the direction in which the incident light enters the light-adjusting element 1.

[0163] Figure 10 is an exploded view of the periscope camera module 100 provided in the embodiment shown in Figure 5 from a second perspective.

[0164] In some optional embodiments, as shown in FIG10, the periscope camera module 100 may further include a front lens 72, which is located on the light-incoming side of the light-directing member 1. The front lens 72 can be used to further improve the utilization rate of the optical path of the periscope camera module 100.

[0165] This helps to reduce the total track length (TTL) of the imaging system of the periscope camera module 100, enabling the electronic device 1000 to achieve a higher zoom ratio.

[0166] In some alternative embodiments, as shown in FIG10, the periscope camera module 100 may further include a first package 73 and a second package 74.

[0167] In some examples, the first encapsulation 73 can be used to close the first opening of the first receiving space 62, and the second encapsulation 74 can be used to close the second opening of the second receiving space 63 and the third opening of the third receiving space 64, thereby limiting and encapsulating the light steering component 1, the first lens group 21, the focusing device 4, the second lens group 22 and the optical image stabilization device 5, and completing the assembly of the periscope camera module 100.

[0168] Figures 11A to 11D are exploded planar views of some of the optical image stabilization devices 5 provided in the embodiments of this application. To facilitate explanation of the structure of the optical image stabilization device 5, Figures 11A to 11D show the second lens group 22 shown in Figure 5. For ease of illustration, the base member 6 shown in Figure 5 is not shown in Figures 11A to 11D.

[0169] In the optical image stabilization device 5, regarding the layout of the magnets (including the first magnet 541, the second magnet 542, etc.) and the guiding structures (including the first guiding structure 511, the second guiding structure 521, etc.), the embodiments of this application provide the following examples:

[0170] In the first example, as shown in Figure 11A, the first structural member 51 can move parallel to the Y direction, and the second structural member 52 can move parallel to the Z direction.

[0171] For example, as shown in FIG11A, the third magnet 543 is a permanent magnet, and the fourth magnet 544 includes a second coil 5402. The third magnet 543 can be fixedly connected to the first structural member 51, and the fourth magnet 544 can be fixedly connected to the second structural member 52.

[0172] For example, the extension direction of the long side of the second coil 5402 can be parallel to the Z direction, and the extension direction of the short side of the second coil 5402 can be parallel to the Y direction. As another example, the magnetic pole direction of the third magnet 543 can be parallel to the Y direction.

[0173] For example, as shown in FIG11A, the first magnet 541 includes a first coil 5401, and the second magnet 542 is a permanent magnet. The first magnet 541 can be fixedly connected to the second structural member 52, and the second magnet 542 can be fixedly connected to the base member 6 shown in FIG5.

[0174] For example, the long side of the first coil 5401 can extend in a direction parallel to the Z direction, and the short side of the first coil 5401 can extend in a direction parallel to the X direction. Similarly, the magnetic pole direction of the second magnet 542 can be parallel to the Z direction.

[0175] For example, as shown in FIG11A, the first guide structure 511 or the second guide structure 521 may extend along the Y direction, and the third guide structure 522 or the fourth guide structure 61 in the base member 6 shown in FIG5 may extend along the Z direction.

[0176] In the first example, both the first coil 5401 and the second coil 5402 are fixedly connected to the second structural member 52, so a power supply architecture that can move with the second structural member 52 can be set up.

[0177] In the first example, the X direction can be the optical axis direction of the second lens group 22, the Z direction can be the second direction, and the Y direction can be the first direction. The second direction can be parallel to the direction in which the incident light enters the light-directing element 1 shown in Figure 8.

[0178] In the second example, as shown in Figure 11B, the third magnet 543 includes a second coil 5402, and the fourth magnet 544 includes a permanent magnet. Unless otherwise specified, the remaining structure or related settings can be referenced to the first example.

[0179] In the second example, the second coil 5402 is fixedly connected to the first structural member 51, and a power supply architecture that can move with the first structural member 51 can be configured.

[0180] In the third example, as shown in Figure 11C, the first structural member 51 can move parallel to the Z direction, and the second structural member 52 can move parallel to the Y direction.

[0181] For example, as shown in FIG11C, the third magnet 543 is a permanent magnet, and the fourth magnet 544 includes a second coil 5402. The third magnet 543 can be fixedly connected to the first structural member 51, and the fourth magnet 544 can be fixedly connected to the second structural member 52.

[0182] For example, the long side of the second coil 5402 can extend in a direction parallel to the Z direction, and the short side of the second coil 5402 can extend in a direction parallel to the X direction. Similarly, the magnetic poles of the third magnet 543 can be parallel to the Z direction.

[0183] For example, as shown in FIG11C, the first magnet 541 includes a first coil 5401, and the second magnet 542 is a permanent magnet. The first magnet 541 can be fixedly connected to the second structural member 52, and the second magnet 542 can be fixedly connected to the base member 6 shown in FIG5.

[0184] For example, the long side of the first coil 5401 can extend in a direction parallel to the Z direction, and the short side of the first coil 5401 can extend in a direction parallel to the Y direction. As another example, the magnetic pole direction of the second magnet 542 can be parallel to the Z direction.

[0185] For example, as shown in FIG11A, the first guide structure 511 or the second guide structure 521 may extend along the Z direction, and the third guide structure 522 or the fourth guide structure 61 in the base member 6 shown in FIG5 may extend along the Y direction.

[0186] In the third example, both the first coil 5401 and the second coil 5402 are fixedly connected to the second structural member 52, so a power supply architecture that can move with the second structural member 52 can be set up.

[0187] In the third example, the X direction can be the optical axis direction of the second lens group 22, the Z direction can be the first direction, and the Y direction can be the second direction. The first direction can be parallel to the direction in which the incident light enters the light-directing element 1 shown in Figure 8.

[0188] In the fourth example, as shown in Figure 11D, the first magnet 541 includes a first coil 5401, the second magnet 542 includes a permanent magnet, the third magnet 543 includes a second coil 5402, and the fourth magnet 544 includes a permanent magnet. Unless otherwise specified, the remaining structures or related settings can be referred to the third example.

[0189] In the fourth example, the second coil 5402 is fixedly connected to the first structural member 51, and a power supply architecture that can move with the first structural member 51 can be set up.

[0190] In other examples, the coil or guide structure can also be selectively set on one side of the second lens group 22 along the direction of the incident light entering the light-directing member 1, so as to meet the optical image stabilization requirements of the periscope camera module 100 while ensuring that the size of the periscope camera module 100 along the direction of the incident light entering the light-directing member 1 is reduced as much as possible.

[0191] In some alternative embodiments, as shown in FIG11A, the optical image stabilization device 5 further includes a first ball 561 located between the first guide structure 511 and the second guide structure 521.

[0192] In some examples, the first guide structure 511 may be a plane in the first structural member 51 that is opposite to the second structural member 52, and the second guide structure 521 may be a plane in the second structural member 52 that is opposite to the first structural member 51.

[0193] In other examples, the first guide structure 511 may be a groove, the second guide structure 521 may be a plane, and a portion of the structure of the first ball 561 is disposed in the groove, while another portion of the structure is exposed outside the groove.

[0194] In some other examples, the first guide structure 511 may be a plane, the second guide structure 521 may be a groove, and a portion of the first ball 561 may be disposed in the groove, while another portion of the ball may be exposed outside the groove.

[0195] Through the above embodiments, the friction between the first guide structure 511 and the second guide structure 521 can be reduced by using ball bearings. This can reduce the driving force used to drive the guide structure, thereby reducing the space and energy consumption of the driving components (such as the first magnet, the second magnet, the third magnet, and the fourth magnet), and also reduce the heat generated by the optical image stabilization device 5 due to friction, thereby reducing the heat generation of the periscope camera module 100. It can also help reduce frictional losses between structural components and extend the life of the optical image stabilization device 5.

[0196] In some optional embodiments, the optical image stabilization device 5 further includes a second ball 562.

[0197] In some alternative embodiments, the second ball 562 is located between the third guide structure 522 and the fourth guide structure 61 in the base 6 shown in FIG. 5.

[0198] In some examples, the third guide structure 522 may be a plane in the second structure 52 opposite to the base member 6, and the fourth guide structure 61 may be a plane in the base member 6 opposite to the second structure 52.

[0199] In other examples, the third guide structure 522 may be a groove, the fourth guide structure 61 may be a plane, and a portion of the first ball 561 may be disposed in the groove, while another portion of the ball may be exposed outside the groove.

[0200] In some other examples, the third guide structure 522 can be a plane, the fourth guide structure 61 can be a groove, and a portion of the first ball 561 is disposed in the groove, while another portion is exposed outside the groove.

[0201] Through the above embodiments, the friction between the third guide structure 522 and the fourth guide structure 61 can be reduced by using ball bearings.

[0203] In some alternative embodiments, the optical axis of the second lens group 22 may intersect the thickness direction of the electronic device 1000, or the direction in which the incident light enters the light steering member 1 may be parallel to the thickness direction of the electronic device 1000. The thickness direction of the electronic device 1000 may be, for example, the Z direction shown in FIG1.

[0204] This application embodiment also provides a method for stabilizing a periscope camera module 100, which can be applied to the electronic device 1000 in the above embodiment. The method includes:

[0205] When the electronic device 1000 vibrates, the second lens group 22 is controlled to move along the first direction, which intersects with the optical axis of the second lens group 22.

[0206] As shown in Figure 1, the first direction can be either the X direction or the Y direction.
