Description

Technical Field

[0001] The present application relates to the field of photography, and more specifically, to a periscope camera module and a reflective device thereof. Background Art

[0002] Because people's hands shake when using electronic devices to take pictures, this will cause the electronic device to focus inaccurately, resulting in blurred photos and poor image quality. The main function of optical image stabilization (OIS) is to compensate for the displacement of optical components caused by user hand shaking. Periscope camera modules generally include a lens device, a reflector device, and an image sensor. For the periscope camera module in the related art, the optical image stabilization of the reflector device is achieved by driving the prism to rotate.

[0047] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described herein.

[0048] In this application, the terms "first", "second", etc. are used to distinguish different objects rather than to describe a specific order. In addition, the terms "include", "have" and any variations thereof are intended to cover non-exclusive inclusions.

[0049] Although terms such as "center," "lateral," "longitudinal," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" may be used in this specification to describe various exemplary features and elements, these terms are used herein for convenience, for example, based on the example orientations shown in the figures and / or orientations in typical use. Nothing in this specification should be construed as requiring a specific three-dimensional or spatial orientation of structures in order to fall within the scope of the claims.

[0050] It should be noted that when an element is fixed to another element, it includes fixing the element directly to the other element or fixing the element to the other element through at least one other element. When an element is connected to another element, it includes connecting the element directly to the other element or connecting the element to the other element through at least one other element.

[0051] like Figures 1 to 15 As shown, the periscope camera module and its reflection device 1 according to the embodiment of the present application are illustrated. Figure 1 and Figure 2 As shown, the periscope camera module includes a reflection device 1, a lens assembly 2 and a photosensitive assembly 3.

[0052] The reflecting device 1 is used to receive light from the subject and redirect the light to the lens assembly 2. In the embodiment of the present application, the reflecting device 1 is configured to redirect the light from the subject by 90 degrees, so that the overall height of the periscope camera module can be reduced. Specifically, the reflecting device 1 is configured to reflect light incident along the first axis direction D1 to the second axis direction D2, wherein the second axis direction D2 is perpendicular to the first axis direction D1.

[0053] The first axis direction D1 is the longitudinal extension direction of the first axis Y. The first axis direction D1 is consistent with the height direction of the periscope camera module and the height direction of the reflector 1. The second axis direction D2 is the longitudinal extension direction of the second axis X. The second axis direction D2 is consistent with the length direction of the periscope camera module and the length direction of the reflector 1.

[0054] The lens assembly 2 is installed on the light reflection path of the reflective device 1 and is located on the light sensing path of the photosensitive component 3. The lens assembly 2 is configured to adjust the light from the reflective device 1, for example, to converge or expand the light.

[0055] The photosensitive component 3 corresponds to the lens assembly 2, and is used to receive light from the lens assembly 2 and perform imaging. The photosensitive component 3 includes a chip circuit board, a photosensitive chip and at least one electronic component. The photosensitive surface of the photosensitive chip faces the lens assembly 2 to receive light emitted from the lens assembly 2. In a specific example, the photosensitive chip is fixed to the side of the chip circuit board facing the lens assembly 2. At least one of the electronic components can be implemented as a passive electronic device such as a capacitor, a resistor, or an active electronic device such as a diode, a memory chip, and at least one of the electronic components can be arranged on the side of the chip circuit board facing the lens assembly 2. In a specific example, the photosensitive chip is electrically connected to the chip circuit board through at least one lead.

[0056] The reflecting device 1 , the lens assembly 2 and the photosensitive assembly 3 are sequentially arranged along the second axis direction D2 .

[0057] For ease of description, this application defines a third axis direction D3, which is perpendicular to the first axis direction D1 and the second axis direction D2. The third axis direction D3 is the length direction of the third axis Z. The third axis direction D3 is consistent with the width direction of the periscope camera module and the width direction of the reflector 1.

[0058] The reflector 1 has an upper side and a lower side that are opposite to each other in the first axial direction D1, a front side and a back side that are opposite to each other in the second axial direction D2, and a first side and a second side that are opposite to each other in the third axial direction D3. The light incident side of the reflector 1 (i.e., the side where light enters the reflector 1) is the upper side of the reflector 1. Correspondingly, the lower side of the reflector 1 is opposite to the light incident side of the reflector 1 in the first axial direction D1. The light exit side of the reflector 1 (i.e., the side where light is emitted from the reflector 1) is the front side of the reflector. Correspondingly, the back side of the reflector 1 is opposite to the light exit side of the reflector 1 in the second axial direction D2. The upper side, lower side, front side, back side, first side, and second side of the components in the reflector 1 are respectively consistent with the upper side, lower side, front side, back side, first side, and second side of the reflector 1.

[0059] The reflecting device 1 includes a reflecting element 10, a shell, a carrier 40, a motor assembly 60 and a conductive assembly. The reflecting element 10 is configured to reflect light incident along the first axis direction D1 to the second axis direction D2. The carrier 40 is used to carry the reflecting element 10. Accordingly, the reflecting element 10 is supported on the carrier 40. The motor assembly 60 is configured to drive the reflecting element 10 to achieve functions such as optical image stabilization and camera angle adjustment. Specifically, the motor assembly 60 is suitable for driving the reflecting element 10 to rotate around the first rotation axis 101 and the second rotation axis 102 to achieve multi-dimensional adjustment. The length extension direction of the first rotation axis 101 is consistent with the first axis direction D1; the length extension direction of the second rotation axis 102 is consistent with the second axis direction D2. Specifically, the motor assembly 60 includes a driving assembly 61, which is configured to drive the carrier 40 to rotate around at least one rotation axis, and includes at least one driving magnet and at least one driving coil. For example, the drive assembly 61 includes a shaking drive assembly and a nodding drive assembly, wherein the shaking drive assembly is configured to drive the reflective element 10 to rotate about the first rotation axis 101, and the nodding drive assembly is configured to drive the reflective element 10 to rotate about the second rotation axis 102. The conductive assembly is used to achieve electrical conduction between the drive assembly 61 or other components requiring electrical conduction and the photosensitive assembly 3 or external devices. The housing is used to accommodate components such as the reflective element 10, the carrier 40, and the motor assembly 60.

[0060] The reflective element 10 can be implemented as a prism (e.g., a triangular prism) or a reflector (e.g., a plane reflector). The reflective element 10 has a light incident surface 11 for receiving light, a light reflecting surface 13 for turning the light, and a light exiting surface 12 for emitting light. For example, when the reflective element 10 is implemented as a prism, the light incident surface 11 of the prism and its light exiting surface 12 are perpendicular to each other, and the light reflecting surface 13 of the prism is inclined at a 45° angle to the light incident surface 11 and the light exiting surface 12. In this way, when light enters the prism perpendicular to the light incident surface 11, the light can be turned 90° at the light reflecting surface 13 and output from the light exiting surface 12 perpendicular to the light exiting surface 12.

[0061] When the reflective element 10 is implemented as a plane reflector, the light incident surface 11, the light emitting surface 12 and the light reflecting surface 13 of the plane reflector are on the same plane, that is, the plane where the light reflecting surface 13 is located. After the light is incident, it can make a 90° turn on the light reflecting surface 13.

[0062] It should be understood that, considering the manufacturing tolerance, the angle at which the reflective element 10 deflects the light may have an error within 1°.

[0063] The shell includes a base 20 and a cover 30 that are interlocked. The base 20 is used to provide a mounting platform for the carrier 40, the motor assembly 60, etc. The cover 30 is interlocked on top of the base 20 to form a relatively closed installation space with the base 20. The cover 30 has an opening 31, wherein the opening 31 corresponds to the reflecting device 1, so that light enters the periscope camera module from the opening 31 of the cover 30 and is incident on the reflecting element 10 of the reflecting device 1. The size of the light incident surface 11 of the reflecting element 10 is less than or equal to the size of the opening 31 of the cover 30, so that all light can enter the reflecting element 10 without being blocked by the cover 30, so as to ensure the amount of light entering.

[0064] The base 20 includes a base bottom wall 21 and base sidewalls extending upward from the base bottom wall 21 and surrounding the base bottom wall 21. The base sidewalls include, in clockwise order, a first base sidewall 22, a second base sidewall 23, and a third base sidewall 24. The first base sidewall 22 and the third base sidewall 24 are opposite to each other in the third axis direction D3. The second base sidewall 23 is located on the back side of the reflecting device 1.

[0065] The reflective element 10 is supported on the carrier 40. The carrier 40 is rotatably mounted on the base 20 so that the carrier 40 can rotate about at least one rotation axis. The carrier 40 includes a carrier body 41 and carrier sidewalls extending upward from the carrier body 41 around the base bottom wall 21. The carrier sidewalls include a first carrier sidewall 42 and a second carrier sidewall 43. The first carrier sidewall 42 and the second carrier sidewall 43 are opposite to each other in the third axial direction D3. The carrier body 41 includes a carrier bottom wall 411, a third carrier sidewall 412 extending upward from the carrier bottom wall 411, and a carrier mounting surface 413 extending between the carrier bottom wall 411 and the third carrier sidewall 412. The carrier bottom wall 411 is located above the base bottom wall 21. The first carrier sidewall 42 and the first base sidewall 22 are opposite each other along the third axis D3. The second carrier sidewall 43 and the third base sidewall 24 are opposite each other along the third axis D3. The third carrier sidewall 412 and the second base sidewall 23 are opposite each other along the second axis D2. The carrier mounting surface 413 extends between the upper side of the third carrier sidewall 412 and the side of the base bottom wall 21 proximal to the lens assembly 2. The entire surface is inclined relative to the horizontal plane, for example, at a 45° angle relative to the horizontal plane, to accommodate the reflective element 10. The carrier body 41, the first carrier sidewall 42, and the second carrier sidewall 43 together form a cavity suitable for accommodating the reflective element 10.

[0066] In some embodiments of the present application, the reflecting device 1 further includes a supporting assembly disposed between the base 20 and the carrier 40 to enable the carrier 40 to be movable relative to the base 20 .

[0067] In some embodiments of the present application, the support assembly includes an intermediate frame 50, a first support portion 91, and a second support portion 92. The intermediate frame 50 is movably disposed between the base 20 and the carrier 40. The carrier 40 and the reflective element 10 are supported by the intermediate frame 50 and are thus movably mounted on the base 20. The first support portion 91 is disposed between the intermediate frame 50 and the base 20, enabling the intermediate frame 50 to rotate relatively smoothly relative to the base 20 about the first rotation axis 101, thereby driving the carrier 40 and the reflective element 10 to rotate relative to the base 20 about the first rotation axis 101. The second support portion 92 is disposed between the intermediate frame 50 and the carrier 40, enabling the carrier 40 to rotate relatively smoothly relative to the intermediate frame 50 and the base 20 about the second rotation axis 102, thereby driving the reflective element 10 to rotate relative to the intermediate frame 50 and the base 20 about the second rotation axis 102.

[0068] Specifically, in one embodiment of the present application, Figure 5 As shown, the first support portion 91 includes a main support member 911 having a spherical structure. The main support member 911 is fixedly mounted on one of the intermediate frame 50 and the base bottom wall 21. The main support member 911 is fixedly mounted on one of the intermediate frame 50 and the base bottom wall 21 by insert molding, integral molding, bonding, or other methods. The other intermediate frame 50 and the base bottom wall 21 are provided with a positioning groove opposite to the main support member 911 in the first axial direction D1, so that the main support member 911 is supported in the positioning groove.

[0069] The first support portion 91 also includes at least one ball 910 to reduce frictional resistance during rotation of the intermediate frame 50 and cooperates with the main support member 911 to form a support plane to stably support the intermediate frame 50. At least one ball groove 920 is provided between the intermediate frame 50 and the base bottom wall 21. Each ball 910 in the first support portion 91 is disposed within the ball groove 920 between the intermediate frame 50 and the base bottom wall 21. For example, the first support portion 91 includes two balls 910; the two balls 910 of the first support portion 91 are disposed opposite each other in the third axial direction D3. Two ball grooves 920 are provided between the intermediate frame 50 and the base bottom wall 21, and the two balls 910 of the first support portion 91 are respectively disposed within the two ball grooves 920 between the intermediate frame 50 and the base bottom wall 21.

[0070] In one example of the present application, the support assembly further includes a ball bearing support 913 disposed below the ball bearing 910 of the first support portion 91. The ball bearing support 913 can be embedded in the intermediate frame 50 or the base 20 through an insert molding process, which can reduce the height of the periscope camera module to a certain extent. The portion of the ball bearing support 913 corresponding to the ball bearing 910 of the first support portion 91 is exposed, providing a flatter support surface for the ball bearing 910 of the first support portion 91 and reducing the risk of dents forming on the ball bearing 910 of the first support portion 91. The ball bearing support 913 can be made of metal.

[0071] The second support portion 92 includes at least one ball 910. At least one ball groove 920 is defined between the intermediate frame 50 and the carrier 40. Each ball 910 in the second support portion 92 is disposed within the ball groove 920 between the intermediate frame 50 and the carrier 40. For example, the second support portion 92 includes two balls 910; the two balls 910 of the second support portion 92 are disposed opposite each other in the third axial direction D3. Two ball grooves 920 are defined between the intermediate frame 50 and the carrier 40, and the two balls 910 of the second support portion 92 are disposed within the two ball grooves 920 between the intermediate frame 50 and the carrier 40, respectively.

[0072] In one example of the present application, the intermediate frame 50 includes a frame body 51, a first frame side portion 52, and a second frame side portion 53. The first frame side portion 52 and the second frame side portion 53 each extend upward from the frame body 51 and are disposed opposite each other along the third axis D3. The carrier 40 has two slots at the bottom; the first frame side portion 52 and the second frame side portion 53 are inserted into the slots. A ball groove 920 is provided between the first frame side portion 52 and the carrier 40, and another ball groove 920 is provided between the second frame side portion 53 and the carrier 40. One ball 910 of the second support portion 92 is disposed in the ball groove 920 between the first frame side portion 52 and the carrier 40; the other ball 910 of the second support portion 92 is disposed in the ball groove 920 between the second frame side portion 53 and the carrier 40.

[0073] In an example of the present application, the first rotating axis 101 penetrates the reflecting element 10 in the first axis direction D1, passes through the carrier 40, the middle frame 50 and the main support member 911 of the first support portion 91, and passes through the base 20; the second rotating axis 102 passes through the reflecting element 10, the carrier 40 and the second support portion 92 in the third axis direction D3, and passes through the base 20.

[0074] It should be understood that the first rotation axis 101 and the second rotation axis 102 can be non-physical rotation axes, that is, the physical first rotation axis 101 and the second rotation axis 102 can be omitted to ensure the flexibility of the intermediate frame 50 and the carrier 40. Even if the physical first rotation axis 101 and the second rotation axis 102 are not provided, the intermediate frame 50 and the carrier 40 can still achieve directional rotation around the virtual first rotation axis 101 and the second rotation axis 102 under a directional driving force.

[0075] Driven by the motor assembly 60, the reflective element 10 rotates around one or more rotational axes to achieve an optical image stabilization function. For example, the reflective element 10 can rotate around a rotational axis parallel to the second axis X. When viewed from the reflective element 10 toward the lens assembly 2, "roll" can indicate the rotational movement of the reflective element 10. For another example, the reflective element 10 can rotate around a rotational axis parallel to the first axis Y. When viewed from the reflective element 10 toward the lens assembly 2, "yaw" can indicate the left-right rotational tilting movement of the reflective element 10. For another example, the reflective element 10 can rotate around a rotational axis parallel to the third axis Z. When viewed from the reflective element 10 toward the lens assembly 2, "pitch" can indicate the up-down rotational tilting movement of the reflective element 10.

[0076] The oscillating drive assembly of the motor assembly 60 includes a first driving magnet 611 and a first driving coil 612 adapted to drive the carrier 40 to rotate about the first rotation axis 101. The nodding drive assembly of the motor assembly 60 includes a second driving magnet 613 and a second driving coil 614 adapted to drive the carrier 40 to rotate about the second rotation axis 102, thereby achieving optical image stabilization. The first driving magnet 611, the first driving coil 612, the second driving magnet 613, and the second driving coil 614 are disposed between the carrier 40 and the base 20. The first driving magnet 611 is disposed in one of the carrier 40 and the base 20, and the first driving coil 612 is disposed in the other of the two. The second driving magnet 613 is disposed in one of the carrier 40 and the base 20, and the second driving coil 614 is disposed in the other of the two. The first driving magnet 611 and the first driving coil 612 are disposed opposite to each other along the second axis direction D2 ; the second driving magnet 613 and the second driving coil 614 are disposed opposite to each other along the second axis direction D2 .

[0077] In one example of the present application, the oscillating drive assembly includes two pairs of the first drive magnets 611 and the first drive coils 612. In the second axial direction D2, the oscillating drive assembly and the nodding drive assembly are both located on the back side of the reflective element 10, for example, on the third carrier side wall 412 and the second base side wall 23. In the third axial direction D3, the two pairs of the first drive magnets 611 and the first drive coils 612 of the oscillating drive assembly are separated on both sides of the nodding drive assembly to provide a larger driving force for the intermediate frame 50 and the carrier 40 thereon, so that the intermediate frame 50 and the carrier 40 thereon can rotate smoothly around the first axis Y.

[0078] Specifically, the two groups of the first driving magnets 611 in the two pairs of the first driving magnets 611 and the first driving coils 612 are located on both sides of the first driving magnet 611 in the third axial direction D3. That is, one group of the first driving magnets 611 is located on one side of the first driving magnet 611 in the third axial direction D3, and the other group of the first driving magnets 611 is located on the other side of the first driving magnet 611 in the third axial direction D3. The two first driving coils 612 in the two pairs of the first driving magnets 611 and the first driving coils 612 are located on both sides of the first driving coil 612 in the third axial direction D3. That is, one first driving coil 612 is located on one side of the first driving coil 612 in the third axial direction D3, and the other first driving coil 612 is located on the other side of the first driving coil 612 in the third axial direction D3. In this example, the first driving magnet 611 and the second driving magnet 613 are centrally disposed on the third carrier side wall 412, and the first driving coil 612 and the second driving coil 614 are centrally disposed on the second base side wall 23. The first driving coil 612 and the second driving coil 614 are centrally disposed on the base 20, so as to facilitate electrical connection with the photosensitive component 3 via a conductive component mounted on the base 20.

[0079] The motor assembly 60 further includes a sensing assembly 64 for sensing the position of the carrier 40 and the reflective element 10 thereon relative to the base 20 , and includes at least one sensing magnet and at least one sensing element disposed between the carrier 40 and the base 20 .

[0080] In one embodiment of the present application, Figure 3As shown, the sensing assembly 64 includes a first sensing magnet 641, a first sensing element 642, a second sensing magnet 643, and a second sensing element 644. The first sensing magnet 641 is opposite to the second driving magnet 613 in a direction perpendicular to the third axis direction D3, for example, opposite to the second driving magnet 613 in the first axis direction D1. The first sensing element 642 is opposite to the second driving magnet 613 and the first sensing magnet 641 in a direction perpendicular to the third axis direction D3, for example, opposite to each other in the second axis direction D2, or opposite to the first sensing magnet 641 in the first axis direction D1.

[0081] In one example of the present application, the first sensing magnet 641 is disposed on the carrier 40. Specifically, the first sensing magnet 641 is disposed on the third carrier sidewall 412. The first sensing element 642 is disposed on the base 20. Specifically, the first sensing element 642 is disposed on the second base sidewall 23.

[0082] In some embodiments of the present application, the first sensing element 642 is adapted to simultaneously sense the magnetic fields of the first sensing magnet 641 and the second driving magnet 613 to determine the rotation angle of the carrier 40 about the third axis Z. It should be understood that if the first sensing magnet 641 is used alone, it needs to have a sufficiently large magnetized area to provide sufficient magnetic field strength, so that the second driving magnet 613 and the first sensing magnet 641 together generate a magnetic field for the first sensing element 642 to operate. This eliminates the need to design the first sensing magnet 641 to be larger in a direction parallel to the relative arrangement of the first sensing magnet 641 and the second driving magnet 613.

[0083] The magnetic poles of the first sensing magnet 641 and the second driving magnet 613 facing each other are opposite to each other, so as to prevent the magnetic repulsion between the first sensing magnet 641 and the second driving magnet 613 from affecting the installation of the first sensing magnet 641 and the second driving magnet 613. It should be understood that if the magnetic poles of the first sensing magnet 641 and the second driving magnet 613 facing each other are the same, the magnetic repulsion between the first sensing magnet 641 and the second driving magnet 613 would make it difficult for the first sensing magnet 641 and the second driving magnet 613 to be close together, and the sensing linearity of the first sensing element 642 would also be poor.

[0084] In order to avoid the magnetic attraction between the first sensing magnet 641 and the second driving magnet 613 causing unexpected displacement of the two, a partition can be set between the first sensing magnet 641 and the second driving magnet 613 to ensure that the first sensing magnet 641 and the second driving magnet 613 are separated in physical structure, and the first sensing magnet 641 and the second driving magnet 613 remain in their respective installation positions.

[0085] In some embodiments of the present application, the side of the first sensing magnet 641 away from the second driving magnet 613 is tilted toward or away from the first sensing element 642. Tilt-setting the first sensing magnet 641 relative to the second driving magnet 613 facilitates greater symmetry in the sensing results of the first sensing element 642 during rotation of the carrier 40 about the third axis Z, thereby calibrating the first sensing element 642. When the side of the first sensing magnet 641 away from the second driving magnet 613 is tilted toward the first sensing element 642, a similar effect can be achieved as when the side of the first sensing magnet 641 away from the second driving magnet 613 is tilted toward the first sensing element 642 at the same angle as when the side of the first sensing magnet 641 away from the second driving magnet 613 is tilted toward the first sensing element 642.

[0086] It is worth noting that, typically, the sensing element is disposed within the drive coil. However, in some embodiments of the present application, the first sensing element 642 is disposed outside the second drive coil 614, for example, on the upper or lower side of the second drive coil 614. Specifically, to meet different drive requirements, the drive current of the second drive coil 614 is not constant during operation, and the magnetic field generated by the second drive coil 614 changes in real time. When the first sensing element 642 is disposed within the second drive coil 614, particularly in the middle of the second drive coil 614, the changing magnetic field of the second drive coil 614 may interfere with the detection of the first sensing element 642. The second drive coil 614 and the first sensing element 642 are disposed simultaneously on the second base sidewall 23, and the first sensing element 642 is disposed outside the second drive coil 614 to reduce the magnetic interference of the second drive coil 614 on the first sensing element 642, thereby improving the accuracy of position detection.

[0087] It is also worth mentioning that the first drive coil 612 and the second drive coil 614 are both disposed on the second base side wall 23, and the first drive magnet 611, the first drive magnet 614, and the first sensing magnet 641 are all disposed on the third carrier side wall 412, which helps reduce magnetic interference from the drive coils and drive magnets on other sides of the carrier 40. The first sensing element 642 is located outside the first drive coil 612, which can reduce magnetic interference from the first drive coil 612 on the first sensing element 642, thereby improving the accuracy of position detection.

[0088] In some embodiments of the present application, the second sensing magnet 643 and the second sensing element 644 are disposed opposite each other in the third axial direction D3. In one example of the present application, the second sensing magnet 643 and the second sensing element 644 are disposed on one side of the carrier 40 in the third axial direction D3. Specifically, the second sensing magnet 643 is disposed on the first carrier sidewall 42, and the second sensing element 644 is disposed on the first base sidewall 22. Alternatively, the second sensing magnet 643 may be disposed on the second carrier sidewall 43, and the second sensing element 644 may be disposed on the third base sidewall 24.

[0089] The first sensing element 642 and the second sensing element 644 can be magnetoresistive sensors, Hall effect sensors, or driver chips with magnetoresistive sensors and / or Hall effect sensors. The first sensing element 642 and the second sensing element 644 can be electrically connected to the photosensitive component 3 via a conductive component mounted on the base 20.

[0090] The motor assembly 60 also includes a magnetic assembly 63 disposed between the carrier 40 and the base 20. The magnetic assembly 63 includes a magnetic magnet 631 and a magnetic yoke 632. The magnetic magnet 631 and the magnetic yoke 632 are located above and below the first support portion 91 and the second support portion 92, and are magnetically attracted to each other, so that the carrier 40, the intermediate frame 50, and the base 20 clamp the first support portion 91 and the second support portion 92 therebetween.

[0091] Specifically, the magnetic magnet 631 is mounted on the carrier 40 and the magnetic yoke 632 is mounted on the base 20, or the magnetic magnet 631 is mounted on the base 20 and the magnetic yoke 632 is mounted on the carrier 40. Preferably, the magnetic magnet 631 is mounted on the carrier bottom wall 411 and the magnetic yoke 632 is mounted on the base bottom wall 21, or the magnetic magnet 631 is mounted on the base bottom wall 21 and the magnetic yoke 632 is mounted on the carrier bottom wall 411.

[0092] In one example of the present application, the magnetic attraction component 63 includes two magnetic magnets 631 and two magnetic yokes 632. The two magnetic magnets 631 are arranged relative to each other in the third axis direction D3, and the two magnetic yokes 632 are arranged relative to each other in the third axis direction D3. One of the two magnetic magnets 631 and one of the two magnetic yokes 632 are arranged relative to each other in the first axis direction D1, and are separated on the upper and lower sides of the first support part 91 to form a first magnetic pair; the other of the two magnetic magnets 631 and the other of the two magnetic yokes 632 are arranged relative to each other in the first axis direction D1, and are separated on the upper and lower sides of the first support part 91 to form a second magnetic pair. In this example, the magnetic magnet 631 is mounted on the carrier bottom wall 411 and the middle frame 50 , and the magnetic yoke 632 is mounted on the base bottom wall 21 .

[0093] In one example of the present application, the magnetic yoke 632 is embedded in the base 20 through an insert molding process, which can reduce the height of the periscope camera module to a certain extent. The portion of the magnetic yoke 632 corresponding to the magnetic magnet 631 can be exposed to ensure the magnetic attraction between the magnetic magnet 631 and the magnetic yoke 632.

[0094] It is worth mentioning that Figure 6 As shown, in the initial state of the reflective element 10 of the reflective device 1, the straight line where the edge of the reflective element 10 (ie, the incident edge 111) and the straight line where the edge of the opening 31 (ie, the opening edge 311) are located on the same side are parallel to each other.

[0095] like Figure 7As shown, when the reflective element 10 is driven to rotate, the straight lines of the incident edge 111 and the opening edge 311 on the same side are tilted to each other, forming a certain angle. When the reflective device 1 has no reset capability or a weak reset capability, the reflective element 10 remains in a tilted state after the power is turned off until the next time the reflective element 10 is driven to rotate. The problems in this case are: 1. After the power is turned off, the tilted state of the reflective element 10 will affect the appearance of the periscope camera module, making consumers feel that the reflective element 10 is "tilted" in the periscope camera module, affecting the aesthetics of the product; 2. The reflective element 10 in a tilted state will no longer be adjusted based on the initial state when it is driven next time, which may make the drive control more difficult and may also affect the effect of optical image stabilization.

[0096] Specifically, the reasons for the above-mentioned problem No. 2 include: (1) When the reflective element 10 is in a tilted state, its initial position has deviated from the designed reference point. At this time, the control algorithm needs to first determine the actual position of the reflective element 10, and then calculate the compensation angle relative to the current tilt position based on the direction and amplitude of the hand shake. This is equivalent to adding additional calculation steps to the original control logic, making the control algorithm more complicated. (2) Since the tilt state of the reflective element 10 is dynamic, the initial position needs to be recalibrated each time it is driven. This dynamic adjustment will lead to error accumulation. If the control algorithm cannot accurately measure the current tilt angle of the reflective element 10, or cannot accurately calculate the compensation angle, it will lead to inaccurate compensation effect, thereby affecting the overall performance of optical image stabilization.

[0097] Therefore, the present application provides a correction structure in the reflecting device 1 to ensure that the reflecting element 10 maintains the initial state in the non-working state (ie, the non-powered state) to avoid the above-mentioned problems.

[0098] Accordingly, in the embodiment of the present application, the motor assembly 60 further includes a calibration assembly 62. The calibration assembly 62 is installed between the carrier 40 and the base 20 and is configured to calibrate the position of the reflective element 10 to a preset initial position. The initial position is the initial state of the reflective element 10 in a non-operating state (i.e., a non-powered state).

[0099] It is worth mentioning that in the architecture of the reflecting device 1, the shaking drive assembly and the nodding drive assembly are centrally arranged on the back of the reflecting device 1 in the second axis direction D2, for example, on the back side of the reflecting element 10, and the supporting assembly and the magnetic attraction assembly 63 are arranged on the lower part of the reflecting device 1 in the first axis direction D1, for example, on the lower side of the reflecting element 10. Therefore, in the embodiment of the present application, the correction assembly 62 is arranged on the first side and the second side of the reflecting device 1, for example, the first side and the second side of the reflecting element 10, so that the distribution of components such as the driving assembly 61, the correction assembly 62, the magnetic attraction assembly 63 and the sensing assembly 64 is more balanced, the dimensions of the reflecting device 1 in all directions are more balanced, and the structure of the reflecting device 1 is more compact. Furthermore, the driving magnet of the driving assembly 61 and the magnetic attraction magnet 631 of the magnetic attraction assembly 63 are relatively large in size, and the correction assembly 62, the driving assembly 61 and the magnetic attraction assembly 63 are respectively arranged on different sides of the reflecting device 1, which can avoid magnetic interference to a certain extent.

[0100] Accordingly, the correction component 62 and the magnetic attraction component 63 are arranged in different directions of the reflective element 10 . The correction component 62 and the driving component 61 are also arranged in different directions of the reflective element 10 .

[0101] In some embodiments of the present application, the correction assembly 62 includes a first correction mechanism 621 and a second correction mechanism 622. The first correction mechanism 621 and the second correction mechanism 622 are located on two sides (ie, the first side and the second side) of the reflective element 10 along the third axis direction D3.

[0102] In some embodiments of the present application, the center of the first correction mechanism 621 and the center of the second correction mechanism 622 are located on an axis, and the length of the axis extending from the line connecting the center of the first correction mechanism 621 and the center of the second correction mechanism 622 is perpendicular to the first axis direction D1. For example, the center of the first correction mechanism 621 and the center of the second correction mechanism 622 are located on an axis extending along the third axis direction D3. As can be seen from the above, the length of the first rotation axis 101 is consistent with the first axis direction D1. Therefore, the line connecting the center of the first correction mechanism 621 and the center of the second correction mechanism 622 is perpendicular to the length of the first rotation axis 101. In this way, when the first correction mechanism 621 and the second correction mechanism 622 are in operation, the correction force generated by the first correction mechanism 621 and the second correction mechanism 622 also acts around the first rotation axis 101.

[0103] Furthermore, when the reflective element 10 is in the initial state, the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622 are symmetrical about the second axis X, which can enable the reflective element 10 to remain in the initial state under the action of the symmetrical correction forces, thereby helping to improve the stability and accuracy of the resetting of the reflective element 10. The symmetry of the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622 means that the directions of the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622 are opposite, and the magnitudes of the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622 are equal.

[0104] It should be understood that if the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622 are asymmetric, for example, the directions of the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622 are the same, then the reflective element 10 may not be able to maintain its initial state, and may even have a tendency to rotate, which cannot solve the technical problem raised in the present application, namely, when the reflective device 1 has no reset ability or weak reset ability, the reflective element 10 is still in a tilted state after the power is turned off, causing problems such as product aesthetics and drive control.

[0105] Figure 8 and Figure 9The diagram shows a situation where the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622 are asymmetric. When the directions of the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622 are consistent, although the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622 can also push the reflective element 10 to move, since there is no force in the opposite direction of the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622, the carrier 40 and the reflective element 10 will have a movement tendency in the direction of the correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622, and will not return to the initial position.

[0106] In one embodiment of the present application, Figure 4 As shown, the first calibration mechanism 621 includes a first magnetic member 6211 and a second magnetic member 6212 spaced apart from each other; the second calibration mechanism 622 includes a third magnetic member 6221 and a fourth magnetic member 6222 spaced apart from each other. The center of the first calibration mechanism 621 is the center of the line connecting the center of the first magnetic member 6211 and the center of the second magnetic member 6212; the center of the second calibration mechanism 622 is the center of the line connecting the center of the third magnetic member 6221 and the center of the fourth magnetic member 6222.

[0107] The first magnetic member 6211 is provided on the carrier 40, and the second magnetic member 6212 is provided on the base 20. Specifically, the first magnetic member 6211 is provided on the first carrier side wall 42, and the second magnetic member 6212 is provided on the first base side wall 22. Figure 10 As shown, the magnetic poles of the opposing surfaces of the first magnetic member 6211 and the second magnetic member 6212 have the same polarity. For example, the magnetic pole of the first magnetic member 6211 facing the second magnetic member 6212 is the north pole, and the magnetic pole away from the second magnetic member 6212 is the south pole, while the magnetic pole of the second magnetic member 6212 facing the first magnetic member 6211 is the north pole, and the magnetic pole away from the first magnetic member 6211 is the south pole; or, the magnetic pole of the first magnetic member 6211 facing the second magnetic member 6212 is the south pole, and the magnetic pole away from the second magnetic member 6212 is the north pole, while the magnetic pole of the second magnetic member 6212 facing the first magnetic member 6211 is the south pole, and the magnetic pole away from the first magnetic member 6211 is the north pole.

[0108] In this way, a first repulsive force exists between the first magnetic member 6211 and the second magnetic member 6212, and the first magnetic member 6211 and the second magnetic member 6212 are not in contact with each other. The first repulsive force refers to the magnetic repulsive force between the first magnetic member 6211 and the second magnetic member 6212 acting on the carrier 40 and the reflective element 10, that is, the correction force F1 of the first correction mechanism 621. In other words, when the force between the first magnetic member 6211 and the second magnetic member 6212 acting on the carrier 40 and the reflective element 10 is a magnetic repulsive force, the correction force F1 of the first correction mechanism 621 is the magnetic repulsive force between the first magnetic member 6211 and the second magnetic member 6212 acting on the carrier 40 and the reflective element 10.

[0109] The third magnetic member 6221 is arranged on the carrier 40, and the fourth magnetic member 6222 is arranged on the base 20; specifically, the third magnetic member 6221 is arranged on the side wall 43 of the second carrier, and the fourth magnetic member 6222 is arranged on the side wall 24 of the third base. The magnetic poles of the surfaces opposite to each other of the third magnetic member 6221 and the fourth magnetic member 6222 are the same. For example, the third magnetic member 6221 is N-pole facing the magnetic pole of the fourth magnetic member 6222, and is away from the magnetic pole. The magnetic pole of the fourth magnetic component 6222 is the S pole, the magnetic pole of the fourth magnetic component 6222 is the N pole facing the third magnetic component 6221, and the magnetic pole away from the third magnetic component 6221 is the S pole; or, the magnetic pole of the third magnetic component 6221 is the S pole facing the fourth magnetic component 6222, and the magnetic pole away from the fourth magnetic component 6222 is the N pole, and the magnetic pole of the fourth magnetic component 6222 is the S pole facing the third magnetic component 6221, and the magnetic pole away from the third magnetic component 6221 is the N pole.

[0110] In this way, a second repulsive force exists between the third magnetic member 6221 and the fourth magnetic member 6222, and the third magnetic member 6221 and the fourth magnetic member 6222 do not contact each other. The second repulsive force refers to the magnetic repulsive force between the third magnetic member 6221 and the fourth magnetic member 6222 acting on the carrier 40 and the reflective element 10, that is, the correction force F2 of the second correction mechanism 622. In other words, when the force between the third magnetic member 6221 and the fourth magnetic member 6222 acting on the carrier 40 and the reflective element 10 is a magnetic repulsive force, the correction force F2 of the second correction mechanism 622 is the magnetic repulsive force between the third magnetic member 6221 and the fourth magnetic member 6222 acting on the carrier 40 and the reflective element 10.

[0111] Accordingly, the first repulsive force and the second repulsive force are in opposite directions. When the first drive coil 612 of the oscillating drive assembly and the second drive coil 614 of the nodding drive assembly are de-energized, even if the reflective element 10 is tilted relative to the opening 31 of the housing, under the action of the first repulsive force and the second repulsive force, the reflective element 10 can rotate around the first rotation axis 101 to its initial position, so that the reflective edge and the opening edge 311 on the same side are parallel to each other.

[0112] In one embodiment of the present application, when the reflective element 10 is in an initial state, the distance between the first magnetic member 6211 and the second magnetic member 6212 is equal to the distance between the third magnetic member 6221 and the fourth magnetic member 6222, and the first repulsive force and the second repulsive force are equal. The smaller the distance between the first magnetic member 6211 and the second magnetic member 6212, the greater the first repulsive force; the larger the distance between the third magnetic member 6221 and the fourth magnetic member 6222, the smaller the second repulsive force. The larger the distance between the first magnetic member 6211 and the second magnetic member 6212, the smaller the first repulsive force; the smaller the distance between the third magnetic member 6221 and the fourth magnetic member 6222, the greater the second repulsive force.

[0113] When the distance between the first magnetic member 6211 and the second magnetic member 6212 is less than the distance between the third magnetic member 6221 and the fourth magnetic member 6222, the first repulsive force pushes the carrier 40 to rotate about the first rotation axis 101, so that the distance between the first magnetic member 6211 and the second magnetic member 6212 is equal to the distance between the third magnetic member 6221 and the fourth magnetic member 6222, and the first repulsive force and the second repulsive force are of the same magnitude and in opposite directions. The symmetry of the first repulsive force and the second repulsive force causes the reflective element 10 of the reflective device 1 to be in a balanced state, that is, to return to its initial state.

[0114] When the distance between the first magnetic member 6211 and the second magnetic member 6212 is greater than the distance between the third magnetic member 6221 and the fourth magnetic member 6222, the second repulsive force pushes the carrier 40 to rotate about the first rotation axis 101 so that the distance between the first magnetic member 6211 and the second magnetic member 6212 is equal to the distance between the third magnetic member 6221 and the fourth magnetic member 6222, and the first repulsive force and the second repulsive force are equal in magnitude and opposite in direction. The symmetry of the first repulsive force and the second repulsive force causes the reflective element 10 of the reflective device 1 to be in a balanced state, that is, to return to its initial state.

[0115] The magnetic pole directions (from the north pole to the south pole) of the first magnetic member 6211, the second magnetic member 6212, the third magnetic member 6221, and the fourth magnetic member 6222 are intersected by an axis, or are coaxial. Although coaxial, the magnetic pole directions of the first magnetic member 6211 and the second magnetic member 6212 are symmetrical, i.e., opposite, and the magnetic pole directions of the third magnetic member 6221 and the fourth magnetic member 6222 are symmetrical, i.e., opposite.

[0116] In one embodiment of the present application, the first magnetic member 6211 , the second magnetic member 6212 , the third magnetic member 6221 , and the fourth magnetic member 6222 are implemented as magnetic magnets.

[0117] In one embodiment of the present application, Figure 11 As shown, the magnetic poles of the opposing surfaces of the first magnetic member 6211 and the second magnetic member 6212 are opposite in polarity. For example, the magnetic pole of the first magnetic member 6211 facing the second magnetic member 6212 is the north pole, and the magnetic pole away from the second magnetic member 6212 is the south pole, while the magnetic pole of the second magnetic member 6212 facing the first magnetic member 6211 is the south pole, and the magnetic pole away from the first magnetic member 6211 is the north pole; or, the magnetic pole of the first magnetic member 6211 facing the second magnetic member 6212 is the south pole, and the magnetic pole away from the second magnetic member 6212 is the north pole, while the magnetic pole of the second magnetic member 6212 facing the first magnetic member 6211 is the north pole, and the magnetic pole away from the first magnetic member 6211 is the south pole.

[0118] In this way, a first attractive force exists between the first magnetic member 6211 and the second magnetic member 6212. The first attractive force refers to the magnetic attraction force between the first magnetic member 6211 and the second magnetic member 6212 acting on the carrier 40 and the reflective element 10, that is, the correction force F1 of the first correction mechanism 621. In other words, when the force between the first magnetic member 6211 and the second magnetic member 6212 acting on the carrier 40 and the reflective element 10 is a magnetic attraction force, the correction force F1 of the first correction mechanism 621 is the magnetic attraction force between the first magnetic member 6211 and the second magnetic member 6212 acting on the carrier 40 and the reflective element 10.

[0119] The magnetic poles of the opposing surfaces of the third magnetic component 6221 and the fourth magnetic component 6222 are opposite in polarity. For example, the magnetic pole of the third magnetic component 6221 facing the fourth magnetic component 6222 is the N pole, and the magnetic pole away from the fourth magnetic component 6222 is the S pole. The magnetic pole of the fourth magnetic component 6222 facing the third magnetic component 6221 is the S pole, and the magnetic pole away from the third magnetic component 6221 is the N pole. Alternatively, the magnetic pole of the third magnetic component 6221 facing the fourth magnetic component 6222 is the S pole, and the magnetic pole away from the fourth magnetic component 6222 is the N pole. The magnetic pole of the fourth magnetic component 6222 facing the third magnetic component 6221 is the N pole, and the magnetic pole away from the third magnetic component 6221 is the S pole.

[0120] In this way, a second attractive force exists between the third magnetic member 6221 and the fourth magnetic member 6222. The second attractive force refers to the magnetic attraction force between the third magnetic member 6221 and the fourth magnetic member 6222 acting on the carrier 40 and the reflective element 10, that is, the correction force F2 of the second correction mechanism 622. In other words, when the force between the third magnetic member 6221 and the fourth magnetic member 6222 acting on the carrier 40 and the reflective element 10 is a magnetic attraction force, the correction force F2 of the second correction mechanism 622 is the magnetic attraction force between the third magnetic member 6221 and the fourth magnetic member 6222 acting on the carrier 40 and the reflective element 10.

[0121] Accordingly, the first suction force and the second suction force are in opposite directions. When the first drive coil 612 of the oscillating drive assembly and the second drive coil 614 of the nodding drive assembly are de-energized, even if the reflective element 10 is tilted relative to the opening 31 of the housing, under the action of the first suction force and the second suction force, the reflective element 10 can rotate around the first rotation axis 101 to the initial position, so that the reflective edge and the opening edge 311 on the same side are parallel to each other.

[0122] The magnetic pole directions (from the north pole to the south pole) of the first magnetic member 6211, the second magnetic member 6212, the third magnetic member 6221, and the fourth magnetic member 6222 are intersected by an axis, or are coaxial. Although coaxial, the magnetic pole directions of the first magnetic member 6211 and the second magnetic member 6212 are the same, and the magnetic pole directions of the third magnetic member 6221 and the fourth magnetic member 6222 are the same.

[0123] In one embodiment of the present application, the first magnetic member 6211 is implemented as a magnet or a yoke, and the second magnetic member 6212 is implemented as the other of the magnet or the yoke. For example, if the first magnetic member 6211 is implemented as a magnet, the second magnetic member 6212 is implemented as a yoke, or if the first magnetic member 6211 is implemented as a yoke, the second magnetic member 6212 is implemented as a magnet. The third magnetic member 6221 is implemented as a magnet or a yoke, and the fourth magnetic member 6222 is implemented as the other of the magnet or the yoke. For example, if the third magnetic member 6221 is implemented as a magnet, the fourth magnetic member 6222 is implemented as a yoke, or if the third magnetic member 6221 is implemented as a yoke, the fourth magnetic member 6222 is implemented as a magnet.

[0124] In another embodiment of the present application, the first magnetic member 6211 , the second magnetic member 6212 , the third magnetic member 6221 , and the fourth magnetic member 6222 are implemented as magnetic magnets.

[0125] It is worth mentioning that in conventional reflecting devices, a magnetic component 63 is required to clamp the ball 910 of the support portion through the magnetic force generated by the magnetic component 63, and when the carrier 40 rotates, the magnetic force between the magnetic yoke 632 and the magnetic magnet 631 of the magnetic component 63 also has a reset function. However, in the embodiment of the present application, the magnetic component 63 is arranged at the bottom, that is, the lower part, of the reflecting device 1. For example, the magnetic magnet 631 is arranged on the bottom side of the carrier 40, and the magnetic yoke 632 is arranged on the bottom wall 21 of the base. When the magnetic magnet 631 and the magnetic yoke 632 are not directly aligned along the first axis direction D1, or when the carrier 40 drives the magnetic magnet 631 to rotate, there is a certain deflection angle between the magnetic magnet 631 and the magnetic yoke 632. In this case, the magnetic attraction force between the magnetic magnet 631 and the magnetic yoke 632 is inclined relative to the first axis Y, that is, the direction of the magnetic attraction force between the magnetic magnet 631 and the magnetic yoke 632 has a certain angle with the first axis direction D1. In this case, the force used to reset the magnetic magnet 631 and the magnetic yoke 632 is the component force of the magnetic attraction force between the two, that is, the reset force generated by the magnetic component 63 is relatively small.

[0126] Based on this, the present application proposes increasing the torque of the force exerted by the correction assembly 62 on the carrier 40 and the reflective element 10 to improve the resetting effect. According to the formula T = F × D, i.e., torque = force × lever arm, the torque is equal to the product of the lever arm and the force value. When the force values ​​are equal, the size of the lever arm determines the magnitude of the torque corresponding to the magnetic force. The longer the lever arm, the greater the torque and the greater the resetting effect.

[0127] The effective arm of the magnetic member in the calibration assembly 62 is equal to the distance from the first rotation axis 101 to the magnetic member in the calibration assembly 62 along the second axis direction D2, which is expressed as the effective arm of the magnetic member in the calibration assembly 62 is equal to the perpendicular distance from the first rotation axis 101 to the line of action of the magnetic force of the magnetic member in the calibration assembly 62. The line of action of the magnetic force of the magnetic member in the calibration assembly 62 is the line connecting the center of the first magnetic member 6211, the center of the second magnetic member 6212, the center of the third magnetic member 6221, and the center of the fourth magnetic member 6222.

[0128] Accordingly, in the embodiment of the present application, along the second axis direction D2, the magnetic member in the correction assembly 62 is farther away from the first rotation axis 101 than the magnetic magnet 631. Figure 12As shown, the distance d1 between the center of the correction component 62 and the first rotation axis 101 in the second axis direction D2 is greater than the distance d2 between the center of the magnetic attraction magnet 631 and the first rotation axis 101 in the second axis direction D2. In this way, the correction torque of the magnetic member in the correction component 62 is greater, that is, the torque of the magnetic member in the correction component 62 acting on the carrier 40 and the reflective element 10 is greater, and the correction effect is better. The center of the correction component 62 is the center of the line connecting the center of the first magnetic member 6211, the center of the second magnetic member 6212, the center of the third magnetic member 6221, and the center of the fourth magnetic member 6222. When there is only one magnetic attraction magnet 631, the center of the magnetic attraction magnet 631 is the center of the one magnetic attraction magnet 631. When the magnetic attraction component 63 has two or more magnetic attraction magnets 631, the center of the magnetic attraction magnet 631 is the center of the line connecting the centers of the two or more magnetic attraction magnets 631.

[0129] For the magnetic parts in the correction component 62, the force arm corresponding to the magnetic parts in the correction component 62 is longer. When the correction force generated by the magnetic parts in the correction component 62 is small, a large correction torque can be generated, thereby producing a better correction effect. As for the magnetic attraction magnet 631, the force arm corresponding to the magnetic attraction magnet 631 is shorter. When the magnetic attraction force generated by the magnetic attraction magnet 631 is small, the magnetic attraction torque generated will also be very small, resulting in a poor reset effect. In theory, the magnetic attraction force can be increased by increasing the size of the magnetic attraction magnet 631, but the size of the magnetic attraction magnet 631 cannot be increased indefinitely. On the one hand, due to the size limitation of the reflecting device 1, the size of the magnetic attraction magnet 631 is too large and will interfere with other components; on the other hand, the increase in the size of the magnetic attraction magnet 631 will increase the magnetic attraction force. When the driving component 61 drives the reflecting element 10 to rotate, a larger driving force is required, resulting in higher power consumption.

[0130] Therefore, in some embodiments of the present application, the correction component 62 is independently provided outside the magnetic component 63. In this way, in the reflection device 1 of the present application, not only can the magnetic attraction function be realized by the magnetic attraction component 63 so that the support portion is clamped, but the correction and reset function can also be realized by the correction component 62. Furthermore, the distance between the center of the correction component 62 and the first rotating axis 101 in the second axis direction D2 is greater than the distance between the center of the magnetic attraction component 63 and the first rotating axis 101 in the second axis direction D2, so that the magnetic part in the correction component 62 has a larger correction torque and a better correction effect.

[0131] In some embodiments of the present application, in order to ensure sufficient correction torque, the line connecting the orthographic projections of the center of the first correction mechanism 621 and the center of the second correction mechanism 622 on the plane perpendicular to the first axis direction D1 does not overlap with the orthographic projection of the first rotation axis 101 on the plane perpendicular to the first axis direction D1; in other words, the line connecting the orthographic projections of the center of the first correction mechanism 621 and the center of the second correction mechanism 622 on the plane perpendicular to the first axis direction D1 and the orthographic projection of the first rotation axis 101 on the plane perpendicular to the first axis direction D1 have a certain distance in the second axis direction D2, and the center of the first correction mechanism 621 and the center of the second correction mechanism 622 are respectively staggered from the first rotation axis 101 in the second axis direction D2; further, this distance is greater than the distance between the line connecting the orthographic projections of the two magnetic magnets 631 of the magnetic attraction component 63 on the plane perpendicular to the first axis direction D1 and the orthographic projection of the first rotation axis 101 on the plane perpendicular to the first axis direction D1 in the second axis direction D2.

[0132] In one embodiment of the present application, the distance between the center of the correction assembly 62 and the center of the driving magnet in the second axial direction D2 is smaller than the distance between the center of the driving magnet and the first rotating shaft 101 in the second axial direction D2. The center of the plurality of driving magnets is the center of a line connecting the center of the first driving magnet 611 and the center of the second driving magnet 613.

[0133] Furthermore, the distance between the center of the correction assembly 62 and the first rotating shaft 101 in the second axial direction D2 is smaller than the distance between the center of the first driving magnet 611 and the first rotating shaft 101 in the second axial direction D2, thereby achieving a longer correction torque for the magnetic member in the correction mechanism. When two or more first driving magnets 611 are provided, the center of the two or more first driving magnets 611 is the center of a line connecting the centers of the two or more first driving magnets 611 themselves.

[0134] In one embodiment of the present application, the distance between the center of the first driving magnet 611 and the first rotating axis 101 in the second axis direction D2 is greater than the distance between the center of the correction component 62 and the first rotating axis 101 in the second axis direction D2, so that the force arm corresponding to the first driving magnet 611 is larger to ensure sufficient rotational torque and achieve better driving effect. Because the distance between the center of the correction component 62 and the first rotating axis 101 in the second axis direction D2 is also large, at least greater than the distance between the center of the magnetic attraction magnet 631 and the first rotating axis 101 in the second axis direction D2, sufficient correction torque is satisfied while sufficient rotational torque is satisfied, so that the reflection device 1 has both good correction effect and driving effect.

[0135] It should be understood that in other embodiments of the present application, it can be implemented as follows: the distance between the center of the correction component 62 and the first rotation axis 101 in the second axis direction D2 is greater than the distance between the center of the first drive magnet 611 and the first rotation axis 101 in the second axis direction D2. In one example of the present application, the first rotation axis 101 is biased toward the side of the drive component 61 relative to the center of the carrier 40 in the second axis direction D2, the correction component 62 is arranged on the side of the carrier 40 facing the lens assembly 2, and the distance between the center of the correction component 62 and the first rotation axis 101 in the second axis direction D2 is greater than the distance between the center of the first drive magnet 611 and the first rotation axis 101 in the second axis direction D2, so that the reflection device 1 has good correction effect and driving effect at the same time, and can also reduce magnetic interference.

[0136] In the second axis direction D2, the first driving magnet 611 and the magnetic member of the correction assembly 62 can be arranged on the same side of the first rotating shaft 101, or can be separated on opposite sides of the first rotating shaft 101. Accordingly, in some embodiments of the present application, the first correction mechanism 621 and the second correction mechanism 622 are located on the side of the first rotating shaft 101 close to the driving assembly 61 in the second axis direction D2. For example, the driving assembly 61, the first correction mechanism 621, and the second correction mechanism 622 are located on the back side of the first rotating shaft 101 in the second axis direction D2. More specifically, the first correction mechanism 621 and the second correction mechanism 622 are located on the side of the first rotating shaft 101 close to the driving magnet in the second axis direction D2. For example, the driving magnet, the first correction mechanism 621, and the second correction mechanism 622 are located on the back side of the first rotating shaft 101 in the second axis direction D2. While satisfying sufficient rotational torque and sufficient correction torque, the reflection device 1 has both good correction effect and driving effect.

[0137] In some other embodiments of the present application, the first correction mechanism 621 and the second correction mechanism 622 are located on a side of the first rotation axis 101 away from the driving assembly 61 in the second axis direction D2. Figure 14 As shown, for example, the driving assembly 61 is located on the back side of the first rotating shaft 101 in the second axis direction D2, and the first correction mechanism 621 and the second correction mechanism 622 are located on the front side of the first rotating shaft 101 in the second axis direction D2. More specifically, the first correction mechanism 621 and the second correction mechanism 622 are located on the side of the first rotating shaft 101 away from the driving magnet in the second axis direction D2. For example, the driving magnet is located on the back side of the first rotating shaft 101 in the second axis direction D2, and the first correction mechanism 621 and the second correction mechanism 622 are located on the front side of the first rotating shaft 101 in the second axis direction D2. This allows the reflection device 1 to have both good correction and driving effects and reduce magnetic interference.

[0138] In an example of the present application, the first rotating axis 101 is located at the center of the carrier 40 in the second axis direction D2, and the correction component 62 is arranged on the side of the carrier 40 facing the driving component 61, close to the driving magnet of the driving component 61.

[0139] In another example of the present application, the first rotating axis 101 is located at the center of the carrier 40 in the second axis direction D2, and the correction component 62 is arranged on the side of the carrier 40 facing the lens assembly 2, away from the driving magnet of the driving component 61.

[0140] In another example of the present application, the first rotating axis 101 is biased toward the side of the driving assembly 61 relative to the center of the carrier 40 in the second axis direction D2, and the correction assembly 62 is arranged on the side of the carrier 40 facing the lens assembly 2, away from the driving magnet of the driving assembly 61.

[0141] In another example of the present application, the first rotating axis 101 is biased toward the side of the lens assembly 2 relative to the center of the carrier 40 in the second axis direction D2, and the correction assembly 62 is arranged on the side of the carrier 40 facing the driving assembly 61, close to the driving magnet of the driving assembly 61.

[0142] It is worth mentioning that in some embodiments of the present application, the sensing magnet in the sensing component 64 and the magnetic member in the correction component 62 may share a magnet, such as Figure 15 As shown. For example, the second sensing magnet 643 and the first magnetic member 6211 are disposed on the first carrier side wall 42 and share a magnet; the second sensing magnet 643 and the first magnetic member 6211 are disposed on the third carrier side wall 412 and share a magnet. The magnet shared by the sensing magnet and the correction component 62 can be used for both correction and head shaking sensing. This reduces the number of magnets and saves costs.

[0143] It is also worth mentioning that in the above embodiment, the correction component 62, the driving component 61 and the magnetic attraction component 63 are respectively located on different sides of the reflective element 10, so that the dimensions of the reflective device 1 in all directions are more balanced and the structure of the reflective device 1 is more compact. However, in the modified embodiment of the present application, as shown in FIG. Figure 13As shown, the correction component 62 can be disposed on the back side and the front side of the reflective element 10 along the second axis direction D2. For example, the first correction mechanism 621 is disposed on the back side of the reflective element 10, wherein the first magnetic member 6211 in the first correction mechanism 621 is disposed on the back side of the carrier 40, located on the third carrier sidewall 412, and the second magnetic member 6212 is disposed on the second base sidewall 23; the carrier 40 has a fourth carrier sidewall, which is opposite to the third carrier sidewall 412; the second correction mechanism is located on the front side of the reflective element 10, and the second magnetic member 6212 in the second correction mechanism 622 is disposed on the front side of the carrier 40, located on the fourth carrier sidewall. By concentrating the correction component 62 on one side of the reflective element 10, such as the first side or the second side, the structure of the reflective device 1 is made more compact.

[0144] In some embodiments of the present application, the reflective device 1 further includes a buffer assembly 70. The buffer assembly 70 is made of a flexible material, such as silicone. The buffer assembly 70 includes a base buffer component 71. The base buffer component 71 is protrudingly disposed on the outer surface of the base 20 to prevent collision damage when the base 20 moves relative to the cover 30. The base buffer component 71 can be attached to the base 20 by gluing, secondary injection molding, or other methods.

[0145] In one example of the present application, the base buffer component 71 is protrudingly provided on the upper surface of the base side wall, protruding upward in the first axial direction D1 relative to the base side wall to achieve buffering between the base side wall and the cover body 30.

[0146] The buffer assembly 70 may further include a carrier buffer component 72. The carrier buffer component 72 is protrudingly disposed on the outer surface of the carrier 40 to provide cushioning during the movement of the carrier 40, preventing the carrier 40 from colliding with the base 20, the cover 30, the intermediate frame 50, or the lens assembly 2. The carrier buffer component 72 may be attached to the carrier 40 by gluing, overmolding, or other methods.

[0147] In one example of the present application, the carrier buffer member 72 is protrudingly disposed on the upper surfaces of the first carrier sidewall 42 and the second carrier sidewall 43, protruding upward relative to the first carrier sidewall 42 and the second carrier sidewall 43 in the first axial direction D1 to provide a buffer between the carrier 40 and the cover 30. The carrier buffer member 72 may also be protrudingly disposed on the bottom outer surface of the carrier bottom wall 411, protruding downward relative to the first carrier sidewall 42 and the second carrier sidewall 43 in the first axial direction D1 to provide a buffer between the carrier 40 and the intermediate frame 50. The carrier buffer member 72 may also be protrudingly disposed on the outer surfaces of the first carrier sidewall 42 and the second carrier sidewall 43 facing the lens assembly 2, protruding forward relative to the first carrier sidewall 42 and the second carrier sidewall 43 in the second axial direction D2 to provide a buffer between the carrier 40 and the lens assembly 2. The carrier buffer part 72 can also be protrudingly arranged on the two opposite outer surfaces of the first carrier side wall 42 and the second carrier side wall 43 in the third axial direction D3, protruding relative to the first carrier side wall 42 and the second carrier side wall 43 in the third axial direction D3 to achieve buffering between the carrier 40 and the base 20.

[0148] In summary, the periscope camera module and reflector 1 according to the embodiment of the present application are described. The reflector 1 can reasonably arrange the various components, so that the dimensions of the reflector 1 in all directions are relatively balanced while ensuring the functions of each component. For example, magnetic interference between components such as the drive component 61, the correction component 62, and the magnetic attraction component 63 is avoided, thereby achieving better drive function, correction function, and stable support function.
