In contrast, when an element is referred to as being "connected" to another element, it is either directly connected to the other element or indirectly connected via at least one other element.

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

[0052] The reflection device 1 is configured to receive light from a target object and to fold the light to the lens assembly 2. In the present embodiment, the reflection device 1 is configured to fold the light from the target object by 90°, so that the overall height dimension of the periscope camera module can be reduced. Specifically, the reflection device 1 is configured to reflect light incident along a first axis direction D1 to a 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 a length extension direction of a 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 reflection device 1. The second axis direction D2 is a length extension direction of a 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 reflection device 1.

[0054] The lens assembly 2 is mounted on the light reflection path of the reflection device 1 and is located on the light sensing path of the photosensitive assembly 3. The lens assembly 2 is configured to adjust the light from the reflection device 1, e.g., converging, diverging, etc.

[0055] ​​The photosensitive assembly 3 corresponds to the lens assembly 2, and is configured to receive light from the lens assembly 2 and form an image. The photosensitive assembly 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 one specific example, the photosensitive chip is fixed to one side of the chip circuit board facing the lens assembly 2. The at least one electronic component can be implemented as a passive electronic component such as a capacitor or a resistor, or an active electronic component such as a diode or a memory chip. The at least one electronic component can be arranged on the side of the chip circuit board facing the lens assembly 2. In one specific example, the photosensitive chip is electrically connected to the chip circuit board through at least one lead wire.

[0056] The reflection device 1, the lens assembly 2, and the photosensitive assembly 3 are arranged in sequence along the second axial direction D2.

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

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

[0059] The reflection device 1 comprises a reflection element 10, a housing, a carrier 40, a motor assembly 60 and a conductive assembly. The reflection element 10 is configured to reflect light rays incident along a first axis direction D1 to a second axis direction D2. The carrier 40 is used to carry the reflection element 10. Accordingly, the reflection element 10 is supported on the carrier 40. The motor assembly 60 is configured to drive the reflection element 10 to achieve optical anti-shake, camera angle adjustment and other functions. Specifically, the motor assembly 60 is adapted to drive the reflection element 10 to rotate around a first rotation axis 101 and a 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 comprises a driving assembly 61 configured to drive the carrier 40 to rotate around at least one rotation axis, including at least one driving magnet and at least one driving coil. For example, the driving assembly 61 comprises a pan driving assembly and a tilt driving assembly, wherein the pan driving assembly is configured to drive the reflection element 10 to rotate around the first rotation axis 101, and the tilt driving assembly is configured to drive the reflection element 10 to rotate around the second rotation axis 102. The conductive assembly is used to achieve electrical conduction between the driving assembly 61 or other components requiring electrical conduction and a photosensitive assembly 3 or external equipment. The housing is used to accommodate components such as the reflection element 10, the carrier 40 and the motor assembly 60.

[0060] The reflection element 10 can be implemented as a prism (e.g., a triangular prism) or a mirror (e.g., a planar mirror). The reflection element 10 has an incident surface 11 for receiving light rays, a light reflection surface 13 for turning the light rays, and an outgoing surface 12 for emitting the light rays. For example, when the reflection element 10 is implemented as a prism, the incident surface 11 of the prism is perpendicular to the outgoing surface 12, and the light reflection surface 13 of the prism is inclined at an angle of 45° with respect to the incident surface 11 and the outgoing surface 12. In this way, when the light rays enter the prism perpendicularly to the incident surface 11, the light rays can be turned by 90° at the light reflection surface 13 and output from the outgoing surface 12 perpendicularly to the outgoing surface 12.

[0061] When the reflection element 10 is implemented as a planar mirror, the incident surface 11, the outgoing surface 12 and the light reflection surface 13 of the planar mirror are on the same plane, i.e., the plane in which the light reflection surface 13 is located. After the light rays are incident, the light rays can be turned by 90° at the light reflection surface 13.

[0062] It should be appreciated that the angle at which the reflective element 10 turns the light rays can have an error of within 1° considering manufacturing tolerances.

[0063] The housing includes a base 20 and a cover 30 that are buckled to each other. The base 20 is used to provide a mounting platform for the carrier 40, the motor assembly 60, etc. The cover 30 is buckled above the base 20 to form a relatively closed mounting space with the base 20. The cover 30 has an opening 31, wherein the opening 31 corresponds to the reflection device 1, so that the light rays enter the periscopic camera module from the opening 31 of the cover 30 and are incident to the reflective element 10 of the reflection device 1. The size of the light-incident surface 11 of the reflective element 10 is less than or equal to the size of the opening 31 of the cover 30, so that the light rays can all enter the reflective element 10 without being blocked by the cover 30 to ensure the amount of light entering.

[0064] The base 20 includes a base bottom wall 21 and a base side wall extending upward from the base bottom wall 21 around the base bottom wall 21. The base side wall includes, in sequence clockwise, a first base side wall 22, a second base side wall 23, and a third base side wall 24. The first base side wall 22 and the third base side wall 24 are opposite in the third axial direction D3. The second base side wall 23 is located at the back side of the reflection device 1.

[0065] The reflective element 10 is supported by the carrier 40. The carrier 40 is rotatably mounted to the base 20 such that the carrier 40 is rotatable about at least one rotation axis. The carrier 40 comprises a carrier main body 41 and carrier side walls extending upwardly from the carrier main body 41 around the base bottom wall 21. The carrier side walls comprise a first carrier side wall 42 and a second carrier side wall 43. The first carrier side wall 42 and the second carrier side wall 43 are opposite to each other in the third axial direction D3. The carrier main body 41 comprises a carrier bottom wall 411, a third carrier side wall 412 extending upwardly from the carrier bottom wall 411, and a carrier mounting surface 413 extending between the carrier bottom wall 411 and the third carrier side wall 412. The carrier bottom wall 411 is located above the base bottom wall 21, the first carrier side wall 42 is opposite to the first base side wall 22 in the third axial direction D3, the second carrier side wall 43 is opposite to the third base side wall 24 in the third axial direction D3, and the third carrier side wall 412 is opposite to the second base side wall 23 in the second axial direction D2. The carrier mounting surface 413 extends between an upper side of the third carrier side wall 412 and a side of the base bottom wall 21 close to the lens assembly 2, is tilted relative to the horizontal plane, for example, by 45° relative to the horizontal plane, and is configured to mount the reflective element 10. The carrier main body 41, the first carrier side wall 42, and the second carrier side wall 43 enclose a receiving cavity adapted to receive the reflective element 10.

[0066] In some embodiments of the present application, the reflective device 1 further comprises a support assembly disposed between the base 20 and the carrier 40 to enable the movability of the carrier 40 relative to the base 20.

[0067] In some embodiments of the present application, the support assembly comprises an intermediate frame 50, a first support part 91 and a second support part 92. The intermediate frame 50 is movably arranged 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 movably mounted to the base 20 in such a way. The first support part 91 is arranged between the intermediate frame 50 and the base 20, so that the intermediate frame 50 can rotate more 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 part 92 is arranged between the intermediate frame 50 and the carrier 40, so that the carrier 40 can rotate more 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 an embodiment of the present application, as shown in Figure 5 The first support part 91 comprises a main support member 911 having a spherical surface structure. The main support member 911 is fixedly arranged in one of the intermediate frame 50 and the base bottom wall 21. The main support member 911 is fixedly arranged in one of the intermediate frame 50 and the base bottom wall 21 by insert molding, integral molding, bonding or the like, and the other one is provided with a positioning groove opposite to the main support member 911 in the first axis direction D1, so that the main support member 911 is supported in the positioning groove.

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

[0070] In an example of the present application, the support assembly further comprises a ball support 913 arranged below the ball 910 of the first support part 91. The ball support 913 can be embedded in the intermediate frame 50 or the base 20 by insert molding process, which can reduce the height of the periscopic camera module to a certain extent, and the part of the ball support 913 corresponding to the ball 910 of the first support part 91 is exposed to provide a smoother support plane for the ball 910 of the first support part 91, and also can reduce the risk of pits generated by the ball 910 of the first support part 91. The ball support 913 can be made of a metal material.

[0071] The second support part 92 comprises at least one ball 910. At least one ball groove 920 is arranged between the intermediate frame 50 and the carrier 40, and each ball 910 in the second support part 92 is arranged in the ball groove 920 between the intermediate frame 50 and the carrier 40. For example, the second support part 92 comprises two balls 910, the two balls 910 of the second support part 92 are arranged opposite to each other in the third axial direction D3, two ball grooves 920 are arranged opposite to each other in the third axial direction D3 between the intermediate frame 50 and the carrier 40, and the two balls 910 of the second support part 92 are respectively arranged in the two ball grooves 920 between the intermediate frame 50 and the carrier 40.

[0072] In one example of the present application, the intermediate frame 50 includes a frame body 51, a first frame side 52 and a second frame side 53. The first frame side 52 and the second frame side 53 extend upwardly from the frame body 51, respectively, and the first frame side 52 and the second frame side 53 are oppositely arranged in the third axial direction D3. The bottom of the carrier 40 has two insertion slots; the first frame side 52 and the second frame side 53 are inserted into the insertion slots. A ball groove 920 is arranged between the first frame side 52 and the carrier 40, and another ball groove 920 is arranged between the second frame side 53 and the carrier 40. One ball 910 of the second support portion 92 is arranged in the ball groove 920 between the first frame side 52 and the carrier 40; another ball 910 of the second support portion 92 is arranged in the ball groove 920 between the second frame side 53 and the carrier 40.

[0073] In one example of the present application, the first rotating shaft 101 penetrates the reflecting element 10 in the first axial direction D1, penetrates the carrier 40, the intermediate frame 50 and the main support 911 of the first support portion 91, and penetrates the base 20; the second rotating shaft 102 penetrates the reflecting element 10, the carrier 40 and the second support portion 92 in the third axial direction D3, and penetrates the base 20.

[0074] It can be understood that the first rotating shaft 101 and the second rotating shaft 102 can be non-physical rotating shafts, i.e., the first rotating shaft 101 and the second rotating shaft 102 can not be physically arranged to ensure the flexibility of the intermediate frame 50 and the carrier 40. Even if the first rotating shaft 101 and the second rotating shaft 102 are not physically arranged, the intermediate frame 50 and the carrier 40 can be oriented to rotate around the virtual first rotating shaft 101 and the second rotating shaft 102 under the driving force of orientation.

[0075] The reflective element 10 is driven by the motor assembly 60 to rotate around one or more rotation axes to achieve optical image stabilization. For example, the reflective element 10 can rotate around a rotation axis parallel to the second axis X, and when viewed from the reflective element 10 to 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 rotation axis parallel to the first axis Y, and when viewed from the reflective element 10 to the lens assembly 2, "yaw" can indicate the rotational left-right tilting movement of the reflective element 10. For yet another example, the reflective element 10 can rotate around a rotation axis parallel to the third axis Z, and when viewed from the reflective element 10 to the lens assembly 2, "pitch" can indicate the rotational up-down tilting movement of the reflective element 10.

[0076] The yaw driving 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 around the first rotation axis 101, and the nod driving 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 around the second rotation axis 102 to achieve 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 on one of the carrier 40 and the base 20, and the first driving coil 612 is disposed on the other one of the carrier 40 and the base 20. The second driving magnet 613 is disposed on one of the carrier 40 and the base 20, and the second driving coil 614 is disposed on the other one of the carrier 40 and the base 20. The first driving magnet 611 and the first driving coil 612 are oppositely disposed along the second axis direction D2, and the second driving magnet 613 and the second driving coil 614 are oppositely disposed along the second axis direction D2.

[0077] In one example of the present application, the head-tilting driving assembly includes two pairs of the first driving magnets 611 and the first driving coils 612. In the second axial direction D2, both the head-tilting driving assembly and the head-nodding driving assembly are located at the back side of the reflecting element 10, for example, at 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 driving magnets 611 and the first driving coils 612 of the head-tilting driving assembly are located on two sides of the head-nodding driving assembly, so as to provide a larger driving force for the intermediate frame 50 and the carrier 40 thereon, and to enable the intermediate frame 50 and the carrier 40 thereon to rotate smoothly around the first axis Y.

[0078] Specifically, 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 two sides of the first driving magnets 611 in the third axial direction D3, i.e., one group of the first driving magnets 611 is located on one side of the first driving magnets 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 magnets 611 in the third axial direction D3. Two first driving coils 612 in the two pairs of the first driving magnets 611 and the first driving coils 612 are located on two sides of the first driving coils 612 in the third axial direction D3, i.e., one first driving coil 612 is located on one side of the first driving coils 612 in the third axial direction D3, and the other first driving coil 612 is located on the other side of the first driving coils 612 in the third axial direction D3. In this example, the first driving magnets 611 and the second driving magnets 613 are concentratedly arranged at the third carrier side wall 412, and the first driving coils 612 and the second driving coils 614 are concentratedly arranged at the second base side wall 23. The first driving coils 612 and the second driving coils 614 are concentratedly arranged at the base 20, so as to facilitate electrical connection of the conductive assembly mounted on the base 20 and the photosensitive assembly 3.

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

[0080] In one embodiment of the present application, as 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 the second driving magnet 613 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 side wall 412. The first sensing element 642 is disposed on the base 20. Specifically, the first sensing element 642 is disposed on the second base side wall 23.

[0082] In some embodiments of the present application, the first sensing element 642 is adapted to simultaneously sense the magnetic field of the first sensing magnet 641 and the second driving magnet 613 to determine the rotation angle of the carrier 40 around 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 that provides the first sensing element 642 with work, and thus the size of the first sensing magnet 641 in the direction parallel to the relative arrangement direction of the first sensing magnet 641 and the second driving magnet 613 does not have to be designed to be large.

[0083] The magnetic poles of the first sensing magnet 641 and the second driving magnet 613 on the side facing each other are opposite, so as to avoid the magnetic repulsion between the first sensing magnet 641 and the second driving magnet 613 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 on the side facing each other are the same, the magnetic repulsion between the first sensing magnet 641 and the second driving magnet 613 will make it difficult for the first sensing magnet 641 and the second driving magnet 613 to be close, and the sensing linearity of the first sensing element 642 is also poor.

[0084] To avoid the magnetic attraction between the first sensing magnet 641 and the second driving magnet 613 causing the two to produce an undesirable displacement, a partition can be provided 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 physically spaced apart, and the first sensing magnet 641 and the second driving magnet 613 are kept in their respective mounting 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 inclined towards the direction of approaching or moving away from the first sensing element 642. By inclining the first sensing magnet 641 relative to the second driving magnet 613, it is convenient to have better symmetry of the sensing result of the first sensing element 642 during the rotation of the carrier 40 around the third axis Z, so as to calibrate the first sensing element 642. When the side of the first sensing magnet 641 away from the second driving magnet 613 is inclined towards the direction of approaching the first sensing element 642 by the same angle as the side of the first sensing magnet 641 away from the second driving magnet 613 is inclined towards the direction of moving away from the first sensing element 642, similar effects can be achieved.

[0086] It is worth noting that generally, the sensing element is arranged inside the driving coil, however, in some embodiments of the present application, the first sensing element 642 is arranged outside the second driving coil 614, for example, on the upper side or the lower side of the second driving coil 614. Specifically, in order to meet different driving requirements, the driving current of the second driving coil 614 when working is not fixed, and the magnetic field generated by the second driving coil 614 will change in real time. When the first sensing element 642 is arranged inside the second driving coil 614, especially in the middle of the second driving coil 614, the changing magnetic field of the second driving coil 614 will interfere with the detection of the first sensing element 642. The second driving coil 614 and the first sensing element 642 are arranged on the second base sidewall 23 at the same time, and the first sensing element 642 is arranged outside the second driving coil 614, so as to reduce the magnetic interference of the second driving coil 614 on the first sensing element 642, and facilitate to improve the accuracy of position detection.

[0087] It is also worth mentioning that the first drive coil 612 and the second drive coil 614 are arranged on the second base side wall 23, and the first drive magnet 611, the first drive magnet 611 and the first sensing magnet 641 are arranged on the third carrier side wall 412, which is conducive to reducing the magnetic interference of the drive coil and the drive magnet on the other side of the carrier 40. The first sensing element 642 is located outside the first drive coil 612, which can reduce the magnetic interference of the first drive coil 612 on the first sensing element 642, and is conducive to 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 arranged opposite to 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 arranged on one side of the carrier 40 in the third axial direction D3. Specifically, the second sensing magnet 643 is arranged on the first carrier side wall 42, and the second sensing element 644 is arranged on the first base side wall 22. It can also be implemented that the second sensing magnet 643 is arranged on the second carrier side wall 43, and the second sensing element 644 is arranged on the third base side wall 24.

[0089] The first sensing element 642 and the second sensing element 644 can be a magnetoresistance sensor, or a Hall element, or a drive chip with a magnetoresistance sensor and / or a Hall element. The first sensing element 642 and the second sensing element 644 can be electrically connected to the photosensitive assembly 3 through a conductive component mounted on the base 20.

[0090] The motor assembly 60 further comprises a magnetic attraction assembly 63 arranged between the carrier 40 and the base 20. The magnetic attraction assembly 63 comprises a magnetic attraction magnet 631 and a magnetic attraction yoke 632. The magnetic attraction magnet 631 and the magnetic attraction yoke 632 are arranged on the upper and lower sides of the first support part 91 and the second support part 92, respectively, and are magnetically attracted to each other, so that the carrier 40, the intermediate frame 50 and the base 20 clamp the first support part 91 and the second support part 92 therebetween.

[0091] Specifically, the magnetic attraction magnets 631 are mounted on the carrier 40 and the magnetic attraction yokes 632 are mounted on the base 20, or the magnetic attraction magnets 631 are mounted on the base 20 and the magnetic attraction yokes 632 are mounted on the carrier 40. Preferably, the magnetic attraction magnets 631 are mounted on the carrier bottom wall 411 and the magnetic attraction yokes 632 are mounted on the base bottom wall 21, or the magnetic attraction magnets 631 are mounted on the base bottom wall 21 and the magnetic attraction yokes 632 are mounted on the carrier bottom wall 411.

[0092] In one example of the present application, the magnetic attraction assembly 63 includes two magnetic attraction magnets 631 and two magnetic attraction yokes 632. The two magnetic attraction magnets 631 are oppositely arranged in the third axial direction D3, and the two magnetic attraction yokes 632 are oppositely arranged in the third axial direction D3. One of the two magnetic attraction magnets 631 and one of the two magnetic attraction yokes 632 are oppositely arranged in the first axial direction D1, and are separated on the upper and lower sides of the first support part 91, forming a first magnetic attraction pair; the other of the two magnetic attraction magnets 631 and the other of the two magnetic attraction yokes 632 are oppositely arranged in the first axial direction D1, and are separated on the upper and lower sides of the first support part 91, forming a second magnetic attraction pair. In this example, the magnetic attraction magnets 631 are mounted on the carrier bottom wall 411 and the intermediate frame 50, and the magnetic attraction yokes 632 are mounted on the base bottom wall 21.

[0093] In one example of the present application, the magnetic attraction yokes 632 are embedded in the base 20 by an insert molding process, which can reduce the height of the periscopic camera module to some extent. The part of the magnetic attraction yoke 632 corresponding to the magnetic attraction magnet 631 can be exposed to ensure the magnetic attraction force between the magnetic attraction magnet 631 and the magnetic attraction yoke 632.

[0094] It is worth mentioning that, as shown in Figure 6 In the initial state, the straight line where the edges (i.e., the incident edges 111) of the reflection elements 10 on the same side are located is parallel to the straight line where the edges (i.e., the opening edges 311) of the openings 31 are located.

[0095] As shown in Figure 7As shown, when the reflecting element 10 is driven to rotate, the straight lines where the incident edge 111 and the opening edge 311 on the same side are located are inclined to each other and form a certain angle. When the reflecting device 1 has no reset function or weak reset function, the reflecting element 10 is still in an inclined state after the power supply is stopped until the reflecting element 10 is driven to rotate next time. The problems in this case are: 1. After the power supply is stopped, the inclined state of the reflecting element 10 will affect the appearance of the periscope camera module, making consumers feel that the reflecting element 10 is "tilted" in the periscope camera module, affecting the product appearance; 2. The reflecting element 10 in the inclined state is no longer adjusted based on the initial state when it is driven next time, which may make the driving control more difficult and may affect the optical anti-shake effect.

[0096] Specifically, the reasons for the above-mentioned second problem include: (1) When the reflecting element 10 is in an inclined 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 reflecting element 10, and then calculate the compensation angle relative to the current inclined position according to the direction and amplitude of the hand shake. This is equivalent to adding an additional calculation step to the original control logic, making the control algorithm more complex. (2) Since the inclined state of the reflecting element 10 is dynamic, the initial position needs to be calibrated every time it is driven. This dynamic adjustment will cause error accumulation. If the control algorithm cannot accurately measure the current inclined angle of the reflecting element 10 or cannot accurately calculate the compensation angle, the compensation effect will be inaccurate, thereby affecting the overall performance of the optical anti-shake.

[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 (i.e. in the non-powered state) to avoid the above-mentioned problems.

[0098] Correspondingly, in the embodiments of the present application, the motor assembly 60 further comprises a correction assembly 62. The correction assembly 62 is mounted between the carrier 40 and the base 20 and is configured to correct the pose of the reflecting element 10 to a preset original pose. The original pose is the initial state of the reflecting element 10 in the non-working state (i.e. in the non-powered state).

[0099] It is worth mentioning that in the architecture of the reflection device 1, the head shaking driving assembly and the head nodding driving assembly are arranged at the back of the reflection device 1, for example, the back side of the reflection element 10, in the second axis direction D2, the support assembly and the magnetic attraction assembly 63 are arranged at the lower part of the reflection device 1, for example, the lower side of the reflection element 10, in the first axis direction D1, therefore, in the embodiment of the present application, the correction assembly 62 is arranged at the first side and the second side of the reflection device 1, for example, the first side and the second side of the reflection element 10, so that the distribution of the driving assembly 61, the correction assembly 62, the magnetic attraction assembly 63 and the sensing assembly 64 and other components is more balanced, the size of the reflection device 1 in each direction is more balanced, and the structure of the reflection device 1 is more compact. Further, the sizes of the driving magnets of the driving assembly 61 and the magnetic attraction magnets 631 of the magnetic attraction assembly 63 are large, and the arrangement of the correction assembly 62, the driving assembly 61 and the magnetic attraction assembly 63 at different sides of the reflection device 1 can avoid magnetic interference to a certain extent.

[0100] Correspondingly, the correction assembly 62 and the magnetic attraction assembly 63 are arranged in different directions of the reflection element 10. The correction assembly 62 and the driving assembly 61 are also arranged in different directions of the reflection 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 separated along a third axis direction D3 on both sides of the reflection element 10 (i.e., the first side and the second side).

[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 extension direction of the axis on which 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 extension direction of the first rotation axis 101 is consistent with the first axis direction D1, and 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 extension direction of the first rotation axis 101. In this way, when the first correction mechanism 621 and the second correction mechanism 622 are working, the correction forces generated by the first correction mechanism 621 and the second correction mechanism 622 are also acting around the first rotation axis 101.

[0103] Further, when the reflecting 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 reflecting element 10 to be kept in the initial state under the action of symmetrical correction forces, and help to improve the stability and reset accuracy of the reset of the reflecting element 10. The correction force F1 of the first correction mechanism 621 and the correction force F2 of the second correction mechanism 622 are symmetrical, which 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 asymmetrical, 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 reflecting element 10 may not be able to be kept in the initial state, and may also have a tendency of rotational movement, which cannot solve the technical problems proposed in the present application, i.e., when the reflecting device 1 has no reset ability or weak reset ability, the reflecting element 10 still remains in the inclined state after stopping energization, which causes problems of product appearance and driving control.

[0105] Figure 8 and Figure 9In the case where the correction forces F1 of the first correction mechanism 621 and the correction forces F2 of the second correction mechanism 622 are asymmetric, in the case where the directions of the correction forces F1 of the first correction mechanism 621 and the correction forces F2 of the second correction mechanism 622 are consistent, although the correction forces F1 of the first correction mechanism 621 and the correction forces F2 of the second correction mechanism 622 can push the reflective element 10 to move, there is no force opposite to the directions of the correction forces F1 of the first correction mechanism 621 and the correction forces F2 of the second correction mechanism 622, which can make the carrier 40 and the reflective element 10 have a tendency to move in the directions of the correction forces F1 of the first correction mechanism 621 and the correction forces F2 of the second correction mechanism 622, and not return to the initial position.

[0106] In an embodiment of the present application, as shown in Figure 4 the first correction mechanism 621 includes a first magnetic member 6211 and a second magnetic member 6212 spaced from each other, and the second correction mechanism 622 includes a third magnetic member 6221 and a fourth magnetic member 6222 spaced from each other. The center of the first correction 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, and the center of the second correction 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 arranged on the carrier 40, and the second magnetic member 6212 is arranged on the base 20. Specifically, the first magnetic member 6211 is arranged on the first carrier side wall 42, and the second magnetic member 6212 is arranged on the first base side wall 22. As shown in Figure 10 the first magnetic member 6211 and the second magnetic member 6212 have the same magnetic pole polarity on the opposite surfaces. For example, the magnetic pole of the first magnetic member 6211 facing the second magnetic member 6212 is N pole, the magnetic pole of the first magnetic member 6211 facing away from the second magnetic member 6212 is S pole, the magnetic pole of the second magnetic member 6212 facing the first magnetic member 6211 is N pole, and the magnetic pole of the second magnetic member 6212 facing away from the first magnetic member 6211 is S pole; or, the magnetic pole of the first magnetic member 6211 facing the second magnetic member 6212 is S pole, the magnetic pole of the first magnetic member 6211 facing away from the second magnetic member 6212 is N pole, the magnetic pole of the second magnetic member 6212 facing the first magnetic member 6211 is S pole, and the magnetic pole of the second magnetic member 6212 facing away from the first magnetic member 6211 is N pole.

[0108] Thus, the 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. The first repulsive force refers to the magnetic repulsive force acting on the carrier 40 and the reflecting element 10 between the first magnetic member 6211 and the second magnetic member 6212, that is, the correction force F1 of the first correction mechanism 621. In other words, when the force acting on the carrier 40 and the reflecting element 10 between the first magnetic member 6211 and the second magnetic member 6212 is a magnetic repulsive force, the correction force F1 of the first correction mechanism 621 is the magnetic repulsive force acting on the carrier 40 and the reflecting element 10 between the first magnetic member 6211 and the second magnetic member 6212.

[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 second carrier side wall 43, and the fourth magnetic member 6222 is arranged on the third base side wall 24. The opposite surfaces of the third magnetic member 6221 and the fourth magnetic member 6222 have the same magnetic pole polarity. For example, the magnetic pole of the third magnetic member 6221 facing the fourth magnetic member 6222 is N, and the magnetic pole of the third magnetic member 6221 facing away from the fourth magnetic member 6222 is S. The magnetic pole of the fourth magnetic member 6222 facing the third magnetic member 6221 is N, and the magnetic pole of the fourth magnetic member 6222 facing away from the third magnetic member 6221 is S. Alternatively, the magnetic pole of the third magnetic member 6221 facing the fourth magnetic member 6222 is S, and the magnetic pole of the third magnetic member 6221 facing away from the fourth magnetic member 6222 is N. The magnetic pole of the fourth magnetic member 6222 facing the third magnetic member 6221 is S, and the magnetic pole of the fourth magnetic member 6222 facing away from the third magnetic member 6221 is N.

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

[0111] Correspondingly, the first repulsive force and the second repulsive force are opposite in direction. When the first driving coil 612 of the head-tilting driving assembly and the second driving coil 614 of the head-nodding driving assembly stop being energized, even if the reflective element 10 is in a tilted state 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 to an initial position about the first rotation axis 101, so that the reflective edges located on the same side and the opening edge 311 are parallel to each other.

[0112] In an 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 greater the distance between the third magnetic member 6221 and the fourth magnetic member 6222, the smaller the second repulsive force. The greater 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 smaller 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 equal in size and opposite in direction. The symmetrical first repulsive force and the second repulsive force make the reflective element 10 of the reflective device 1 in a balanced state, i.e., return to the 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 around 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 size and opposite in direction. The symmetrical first repulsive force and the second repulsive force make the reflecting element 10 of the reflecting device 1 in a balanced state, i.e., return to the initial state.

[0115] The magnetic pole directions (the direction from the N pole to the S pole) of the first magnetic member 6211, the second magnetic member 6212, the third magnetic member 6221 and the fourth magnetic member 6222 are penetrated by an axis or 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 an 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 an embodiment of the present application, as shown in Figure 11 The magnetic pole directions (the direction from the N pole to the S pole) of the first magnetic member 6211, the second magnetic member 6212, the third magnetic member 6221 and the fourth magnetic member 6222 are penetrated by an axis or 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.

[0118] Thus, the first magnetic member 6211 and the second magnetic member 6212 have a first attractive force. The first attractive force refers to a magnetic attractive force between the first magnetic member 6211 and the second magnetic member 6212 acting on the carrier 40 and the reflective element 10, i.e., 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 attractive force, the correction force F1 of the first correction mechanism 621 is the magnetic attractive 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 opposite surfaces of the third magnetic member 6221 and the fourth magnetic member 6222 have opposite magnetic pole polarities. For example, the magnetic pole of the third magnetic member 6221 facing the fourth magnetic member 6222 is N, and the magnetic pole of the third magnetic member 6221 facing away from the fourth magnetic member 6222 is S. The magnetic pole of the fourth magnetic member 6222 facing the third magnetic member 6221 is S, and the magnetic pole of the fourth magnetic member 6222 facing away from the third magnetic member 6221 is N. Alternatively, the magnetic pole of the third magnetic member 6221 facing the fourth magnetic member 6222 is S, and the magnetic pole of the third magnetic member 6221 facing away from the fourth magnetic member 6222 is N. The magnetic pole of the fourth magnetic member 6222 facing the third magnetic member 6221 is N, and the magnetic pole of the fourth magnetic member 6222 facing away from the third magnetic member 6221 is S.

[0120] Thus, the third magnetic member 6221 and the fourth magnetic member 6222 have a second attractive force. The second attractive force refers to a magnetic attractive force between the third magnetic member 6221 and the fourth magnetic member 6222 acting on the carrier 40 and the reflective element 10, i.e., 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 attractive force, the correction force F2 of the second correction mechanism 622 is the magnetic attractive force between the third magnetic member 6221 and the fourth magnetic member 6222 acting on the carrier 40 and the reflective element 10.

[0121] Correspondingly, the first suction force and the second suction force are in opposite directions. When the first driving coil 612 of the head-shaking driving assembly and the second driving coil 614 of the head-nodding driving assembly stop being energized, even if the reflective element 10 is in a tilted state 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 an initial position, so that the reflective edges located on the same side and the opening edge 311 are parallel to each other.

[0122] The magnetic pole directions (the direction from the N pole to the S pole) of the first magnetic member 6211, the second magnetic member 6212, the third magnetic member 6221, and the fourth magnetic member 6222 are penetrated by an axis or 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 an embodiment of the present application, the first magnetic member 6211 is implemented as one of a magnet or a magnetic yoke, and the second magnetic member 6212 is implemented as the other one of a magnet or a magnetic yoke, for example, if the first magnetic member 6211 is implemented as a magnet, the second magnetic member 6212 is implemented as a magnetic yoke, or if the first magnetic member 6211 is implemented as a magnetic yoke, the second magnetic member 6212 is implemented as a magnet. The third magnetic member 6221 is implemented as one of a magnet or a magnetic yoke, and the fourth magnetic member 6222 is implemented as the other one of a magnet or a magnetic yoke, for example, if the third magnetic member 6221 is implemented as a magnet, the fourth magnetic member 6222 is implemented as a magnetic yoke, or if the third magnetic member 6221 is implemented as a magnetic 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 the conventional reflection device, the magnetic attraction assembly 63 is needed to clamp the ball 910 of the support part by the magnetic attraction force generated by the magnetic attraction assembly 63, and when the carrier 40 rotates, the magnetic attraction force between the magnetic attraction yoke 632 and the magnetic attraction magnet 631 of the magnetic attraction assembly 63 also has a reset function. However, in the embodiment of the present application, the magnetic attraction assembly 63 is arranged at the bottom of the reflection device 1, that is, the lower part, for example, the magnetic attraction magnet 631 is arranged at the bottom side of the carrier 40, and the magnetic attraction yoke 632 is arranged at the base bottom wall 21. When the magnetic attraction magnet 631 is not directly opposite the magnetic attraction yoke 632 along the first axis direction D1, or when the carrier 40 drives the magnetic attraction magnet 631 to rotate, there is a certain deflection angle between the magnetic attraction magnet 631 and the magnetic attraction yoke 632. In this case, the magnetic attraction force between the magnetic attraction magnet 631 and the magnetic attraction yoke 632 is inclined relative to the first axis Y, that is, there is a certain angle between the direction of the magnetic attraction force between the magnetic attraction magnet 631 and the magnetic attraction yoke 632 and the first axis direction D1. In this case, the force for resetting between the magnetic attraction magnet 631 and the magnetic attraction yoke 632 is the component force of the magnetic attraction force of the two, that is, the resetting force generated by the magnetic attraction assembly 63 is smaller.

[0126] Based on this, the present application proposes to increase the moment of the force of the correction assembly 62 on the carrier 40 and the reflection element 10 to improve the resetting effect. According to the formula T=FxD, that is, the moment equals the product of the arm and the force, when the force values are equal, the size of the arm determines the size of the magnetic force corresponding to the moment, the longer the arm, the greater the moment, and the greater the resetting effect.

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

[0128] Correspondingly, in the embodiment of the present application, along the second axis direction D2, the magnetic part in the correction assembly 62 is farther away from the first rotation axis 101 than the magnetic attraction magnet 631. Correspondingly, as shown in FIG. 6, the effective arm of the magnetic part in the correction assembly 62 is greater than the effective arm of the magnetic attraction magnet 631. Figure 12As shown, the distance d1 between the center of the correction assembly 62 and the first rotating shaft 101 in the second axis direction D2 is greater than the distance d2 between the center of the magnetic attracting magnet 631 and the first rotating shaft 101 in the second axis direction D2. In this way, the correction assembly 62 has a greater correction torque of the magnetic component, that is, the correction assembly 62 has a greater torque of the force acting on the carrier 40 and the reflecting element 10, and the correction effect is better. The center of the correction assembly 62 is the center of the line connecting the center of the first magnetic component 6211, the center of the second magnetic component 6212, the center of the third magnetic component 6221, and the center of the fourth magnetic component 6222. When there is only one magnetic attracting magnet 631, the center of the magnetic attracting magnet 631 is the center of the one magnetic attracting magnet 631. When there are two or more magnetic attracting magnets 631 in the magnetic attracting assembly 63, the center of the magnetic attracting magnet 631 is the center of the line connecting the centers of the two or more magnetic attracting magnets 631.

[0129] For the magnetic component in the correction assembly 62, the corresponding force arm of the magnetic component in the correction assembly 62 is longer, and a greater correction torque can be generated even if the correction force generated by the magnetic component in the correction assembly 62 is small, thereby generating a better correction effect. For the magnetic attracting magnet 631, the corresponding force arm of the magnetic attracting magnet 631 is shorter, and the magnetic attracting torque generated by the magnetic attracting magnet 631 is small even if the magnetic attracting force generated by the magnetic attracting magnet 631 is small, thereby generating a poor reset effect. In theory, the magnetic attracting force can be increased by increasing the size of the magnetic attracting magnet 631, but the size of the magnetic attracting magnet 631 cannot be increased indefinitely. On the one hand, due to the size limitation of the reflecting device 1, the magnetic attracting magnet 631 cannot be too large due to interference with other components. On the other hand, increasing the size of the magnetic attracting magnet 631 will increase the magnetic attracting force, and a greater driving force is required when the driving assembly 61 drives the reflecting element 10 to rotate, resulting in higher power consumption.

[0130] Therefore, in some embodiments of the present application, the correction assembly 62 is independently provided outside the magnetic attracting assembly 63. In this way, in the reflecting device 1 of the present application, not only can the magnetic attracting function be realized by the magnetic attracting assembly 63 to clamp the support part, but also the correction reset function can be realized by the correction assembly 62. Further, the distance between the center of the correction assembly 62 and the first rotating shaft 101 in the second axis direction D2 is greater than the distance between the center of the magnetic attracting assembly 63 and the first rotating shaft 101 in the second axis direction D2, so that the magnetic component in the correction assembly 62 has a greater 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 projections of the center of the first correction mechanism 621 and the center of the second correction mechanism 622 on a plane perpendicular to the first axis direction D1 does not overlap with the projection of the first rotation axis 101 on the plane perpendicular to the first axis direction D1; in other words, the line connecting the projections of the center of the first correction mechanism 621 and the center of the second correction mechanism 622 on a plane perpendicular to the first axis direction D1 is spaced apart from the projection of the first rotation axis 101 on the plane perpendicular to the first axis direction D1 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 offset from the first rotation axis 101 in the second axis direction D2; further, the distance between the line connecting the projections of the two magnetic attraction magnets 631 of the magnetic attraction assembly 63 on a plane perpendicular to the first axis direction D1 and the projection of the first rotation axis 101 on the plane perpendicular to the first axis direction D1 in the second axis direction D2 is greater than the distance between the line connecting the projections of the two magnetic attraction magnets 631 of the magnetic attraction assembly 63 on a plane perpendicular to the first axis direction D1 and the 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 an 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 axis direction D2 is less than the distance between the center of the driving magnet and the first rotation axis 101 in the second axis direction D2. The center of the driving magnet is the center of the line connecting the center of the first driving magnet 611 and the center of the second driving magnet 613.

[0133] Further, the distance between the center of the correction assembly 62 and the first rotation axis 101 in the second axis direction D2 is less than the distance between the center of the first driving magnet 611 and the first rotation axis 101 in the second axis direction D2, so as to achieve a longer correction torque of the magnetic member in the correction mechanism. When two or more first driving magnets 611 are provided, the center of the first driving magnet is the center of the line connecting the centers of the two or more first driving magnets 611.

[0134] In an embodiment of the present application, the distance between the center of the first driving magnet 611 and the first rotating shaft 101 in the second shaft direction D2 is greater than the distance between the center of the correction assembly 62 and the first rotating shaft 101 in the second shaft direction D2, so that the first driving magnet 611 has a greater corresponding force arm to ensure sufficient rotational torque and achieve a better driving effect. Since the distance between the center of the correction assembly 62 and the first rotating shaft 101 in the second shaft direction D2 is also greater, at least greater than the distance between the center of the magnetic attraction magnet 631 and the first rotating shaft 101 in the second shaft direction D2, the reflection device 1 simultaneously satisfies sufficient correction torque while satisfying sufficient rotational torque, so that the reflection device 1 has good correction effect and driving effect at the same time.

[0135] It should be understood that in other embodiments of the present application, the distance between the center of the correction assembly 62 and the first rotating shaft 101 in the second shaft direction D2 can be greater than the distance between the center of the first driving magnet 611 and the first rotating shaft 101 in the second shaft direction D2. In one example of the present application, the first rotating shaft 101 is offset to the side where the driving assembly 61 is located relative to the center of the carrier 40 in the second shaft direction D2, the correction assembly 62 is arranged on the side of the carrier 40 facing the lens assembly 2, and the distance between the center of the correction assembly 62 and the first rotating shaft 101 in the second shaft direction D2 is greater than the distance between the center of the first driving magnet 611 and the first rotating shaft 101 in the second shaft 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 axial direction D2, the magnetic components of the first driving magnet 611 and the correction assembly 62 can be disposed on the same side of the first rotating shaft 101, or they can be disposed on opposite sides of the first rotating shaft 101. Accordingly, in some embodiments of this application, the first correction mechanism 621 and the second correction mechanism 622 are located on the side of the first rotating shaft 101 closer to the driving assembly 61 in the second axial 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 axial 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 closer to the driving magnet in the second axial 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 axial direction D2. By satisfying both sufficient rotational torque and sufficient correction torque, the reflecting device 1 simultaneously possesses good correction and driving effects.

[0137] In other embodiments of this application, the first correction mechanism 621 and the second correction mechanism 622 are located on the side of the first rotation axis 101 away from the drive assembly 61 in the second axial direction D2, such as... 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 axial 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 axial 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 axial direction D2. For example, the driving magnet is located on the back side of the first rotating shaft 101 in the second axial 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 axial direction D2. This allows the reflecting device 1 to have both good correction and driving effects, and also reduces magnetic interference.

[0138] In one example of this application, the first rotation axis 101 is located at the center of the carrier 40 in the second axial direction D2, and the correction component 62 is disposed on the side of the carrier 40 facing the drive component 61, close to the drive magnet of the drive component 61.

[0139] In another example of the present application, the first rotation axis 101 is located at 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.

[0140] In another example of the present application, the first rotation axis 101 is located at 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 rotation axis 101 is located at 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.

[0142] It is worth mentioning that, in some embodiments of the present application, the sensing magnet in the sensing assembly 64 and the magnetic piece in the correction assembly 62 can share a magnet, as shown in Figure 15 For example, the second sensing magnet 643 and the first magnetic piece 6211 are arranged on the first carrier side wall 42 and share a magnet; the second sensing magnet 643 and the first magnetic piece 6211 are arranged on the third carrier side wall 412 and share a magnet. The magnet shared by the sensing magnet and the correction assembly 62 can be used to realize the correction function, or can be used to realize the pan sensing. In this way, the number of magnets can be reduced, and the cost can be saved.

[0143] It is also worth mentioning that, in the above-mentioned embodiments, the correction assembly 62, the driving assembly 61 and the magnetic attraction assembly 63 are respectively located on different sides of the reflecting element 10, so that the size of the reflecting device 1 in each direction is balanced, and the structure of the reflecting device 1 is more compact. However, in the variant embodiments of the present application, as shown in Figure 13As shown, the correction assembly 62 can be disposed on the back side and the front side of the reflecting element 10 along the second axial direction D2. For example, the first correction mechanism 621 is disposed on the back side of the reflecting element 10, wherein the first magnetic piece 6211 in the first correction mechanism 621 is disposed on the back side of the carrier 40, located at the third carrier side wall 412, and the second magnetic piece 6212 is disposed on the second base side wall 23; the carrier 40 has a fourth carrier side wall opposite to the third carrier side wall 412, and the second correction mechanism is located on the front side of the reflecting element 10, wherein the second magnetic piece 6212 in the second correction mechanism 622 is disposed on the front side of the carrier 40, located at the fourth carrier side wall. In this way, the correction assembly 62 is concentrated on one side of the reflecting element 10, for example, the first side or the second side, so that the structure of the reflecting device 1 is more compact.

[0144] In some embodiments of the present application, the reflecting device 1 further comprises a buffer assembly 70. The buffer assembly 70 is made of a flexible material, for example, silica gel. The buffer assembly 70 comprises a base buffer component 71. The base buffer component 71 is protrudingly disposed on the outer surface of the base 20 to avoid collision damage when the base 20 moves relative to the cover 30. The base buffer component 71 can be disposed on the base 20 by means of gluing, secondary injection molding, etc.

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

[0146] The buffer assembly 70 can further comprise a carrier buffer component 72. The carrier buffer component 72 is protrudingly disposed on the outer surface of the carrier 40 to achieve buffer during the movement of the carrier 40, so as to avoid collision damage between the carrier 40 and the base 20 or the cover 30 or the intermediate frame 50 or the lens assembly 2. The carrier buffer component 72 can be disposed on the carrier 40 by means of gluing, secondary injection molding, etc.

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

[0148] In summary, the periscopic camera module and the reflecting device 1 according to the embodiments of the present application are illustrated. The reflecting device 1 can reasonably arrange various components, so that the reflecting device 1 has balanced dimensions in each direction while ensuring the functions of each component, for example, avoiding magnetic interference between the driving assembly 61, the correction assembly 62, the magnetic attraction assembly 63 and other components, achieving better driving function, correction function, stable support function, etc.
