[0051] Figure 1 FIG. 1 is a partial structural diagram of an electronic device according to an exemplary embodiment. Figure 1 As shown, the electronic device includes a light-transmitting hole 101 and a periscope camera 102, and the periscope camera 102 can collect external light and form an image through the light-transmitting hole 101. The periscope camera 102 includes a reflective component 112 and an imaging component 113. The light incident surface of the imaging component 113 is arranged toward the light-emitting surface of the reflective component 112, and the light incident surface of the reflective component 112 is arranged toward the light-transmitting hole 101. In this way, the light incident from the light-transmitting hole 101 can first enter the reflective component 112 through the light incident surface of the reflective component 112, and the light is reflected by the reflective component 112 and then enters the light incident surface of the imaging component 113, thereby forming an image in the imaging component 113. Among them, the imaging component 113 may include structures such as an image sensor and a lens, or the imaging component 113 may not include a lens. The specific design is determined as needed, and the present disclosure does not limit this.

[0052] Figure 2 is a structural diagram of a reflective component according to an exemplary embodiment. Figure 3 yes Figure 2Schematic diagram of the decomposition of the reflective components. Figure 2 and Figure 3 As shown, the reflective assembly includes a fixing seat 1, a bracket 2, a driving member 3, a first adsorption member 4 and a second adsorption member 5. The fixing seat 1 can be a shell structure, such as an integrated open shell, or a split openable shell, and the bracket 2 can be used to fix the lens group. For example, the bracket 2 can include a mounting cavity, and the lens group can be fixedly arranged in the mounting cavity. Optionally, the lens group can also be fixed to the bracket by pasting or other means, and the specific shape of the bracket is not limited in the present disclosure. Optionally, the lens group can include optical lenses such as prisms and liquid lenses. The lens group can include a single lens or multiple lenses, which is not provided in the present disclosure. The bracket 2 is assembled in the fixing seat 1, and the bracket 2 and the fixing seat 1 have rotational freedom around a first direction and rotational freedom around a second direction. The first direction is Figure 3 The direction indicated by the arrow A, the second direction is Figure 3 In the direction indicated by the arrow B, the first direction, the second direction and the incident direction of the lens assembly are orthogonal to each other.

[0053] To prevent movement of the bracket 2 within the mounting base 1, the bracket 2 and the mounting base 1 have only one degree of freedom of rotation about a first direction and one degree of freedom of rotation about a second direction. The driver 3 can drive the bracket 2 to rotate about either the first direction or the second direction at any given moment. The driver 3 can take various forms, such as an electrode or a combination of a coil and a magnet, and this disclosure is not limited thereto.

[0054] Based on the rotational freedom of the bracket 2 about the first direction and the rotational freedom about the second direction, when shooting with the periscope camera module equipped with the reflective assembly, the bracket 2 can drive the lens group to rotate about the first direction or about the second direction, thereby achieving optical image stabilization in these two rotational freedom directions. However, since the bracket 2 has these two rotational freedoms within the fixed base 1, before each execution of the optical image stabilization function, the relative positional relationship between the bracket 2 and the fixed base 1 needs to be determined. In order to facilitate the control of the movement of the bracket 2 according to the actual image stabilization requirements, the bracket 2 and the fixed base 1 can be controlled to return to the initial positional relationship after each execution of the image stabilization function. Therefore, before each execution of the optical image stabilization function, the movement of the bracket 2 can be controlled according to the actual requirements based on the state that the bracket 2 and the fixed base 1 are in the initial positional relationship.

[0055] Based on this, the first adsorption member 4 can be arranged on the side of the bracket 2 facing the fixed seat 1, and the second adsorption member 5 can be arranged on the side of the fixed seat 1 facing the bracket 2, and when the fixed seat 1 and the bracket 2 are in an initial position relationship, the first adsorption member 4 and the second adsorption member 5 overlap and are arranged to attract each other, and the direction of the overlapping arrangement between the first adsorption member 4 and the second adsorption member 5 is perpendicular to the first direction and the second direction. For example, the direction of the overlapping arrangement between the first adsorption member 4 and the second adsorption member 5 can be along Figure 3 Arrange in the direction of arrow C.

[0056] In this way, no matter whether the bracket 2 rotates around the first direction relative to the fixing base 1 or rotates around the second direction relative to the fixing base 1, the first adsorption component 4 and the second adsorption component 5 can be misaligned, but a force opposite to the movement direction of the bracket 2 will be generated between the first adsorption component 4 and the second adsorption component 5; when the driving component 3 stops working, the bracket 2 can be automatically reset by the force between the first adsorption component 4 and the second adsorption component 5, so as to maintain the initial position relationship between the bracket 2 and the fixing base 1. Therefore, through the interaction between the first adsorption component 4 and the second adsorption component 5, the system stability of the reflection component can be increased, the initial position relationship between the bracket 2 and the fixing base 1 can be ensured, and the damping effect of the reflection component in the target rotation direction can be increased, thereby enriching the automatic reset function of the reflection component and simplifying the control difficulty of the reflection component.

[0057] For example, the first adsorption component 4 can be one of a magnetic sheet, a magnetic block and a magnetic column, and the second adsorption component 5 can also be one of a magnetic sheet, a magnetic block and a magnetic column. Optionally, when one of the first adsorption component 4 and the second adsorption component 5 is a magnet, the other can be a magnet or a metal component that can be attracted to a magnet. It can be understood that in the embodiment provided in the present disclosure, a group of mutually attractive first adsorption components 4 and second adsorption components 5 are used to maintain the initial position relationship between the bracket 2 and the fixing base 1 as an example. In other embodiments, multiple groups of mutually attractive first adsorption components 4 and second adsorption components 5 can also be provided in the reflective component to maintain the initial position relationship between the bracket 2 and the fixing base 1. The present disclosure does not limit this.

[0058] The aforementioned embodiment is described by taking as an example an embodiment in which the bracket 2 and the fixing base 1 have both rotational freedom about the first direction and rotational freedom about the second direction. In other embodiments, the bracket 2 and the fixing base 1 may have only rotational freedom about the first direction or rotational freedom about the second direction. The specific design can be as needed and is not limited in this disclosure.

[0059] In some embodiments, the rotational freedom of the bracket 2 relative to the fixing base 1 around the first direction and the rotational freedom around the second direction can be achieved by the cooperation between the arc groove provided on the fixing base 1 and the cylindrical block provided on the bracket 2.

[0060] In other embodiments, Figure 4-Figure 6 As shown, the fixing base 1 includes a first limiting groove 11 and a first guide groove 12, and the bracket 2 is provided with a second limiting groove 21 and a second guide groove 22 on the side facing the bottom surface of the fixing base 1. The reflective assembly also includes a cross shaft 6, which includes a first shaft 61 and a second shaft 62 arranged orthogonally, the axial direction of the first shaft 61 is parallel to the first direction, and the axial direction of the second shaft 62 is parallel to the second direction, and the first shaft 61 is penetrated by the first guide groove 12 and the second limiting groove 21, and the second limiting groove 21 can limit the movement of the first shaft 61 in the axial direction of the second shaft 62, that is, the second limiting groove 21 can limit the movement of the first shaft 61 in the second direction indicated by arrow B; similarly, the second shaft 62 is penetrated by the second guide groove 22 and the first limiting groove 11, and the first limiting groove 11 can limit the movement of the second shaft 62 in the axial direction of the first shaft 61, that is, the first limiting groove 11 can limit the movement of the second shaft 62 in the first direction indicated by arrow A.

[0061] Due to the cooperation between the second rotating shaft 62 and the first limiting groove 11, the movement of the bracket 2 relative to the fixing base 1 in the direction indicated by the arrow C can be restricted. In the second direction, the second guide groove 22 cooperates with the second rotating shaft 62 for guidance. Under the guidance of the second guide groove 22, the bracket 2 can rotate relative to the second rotating shaft 62, while the first rotating shaft 61 can slightly swing within the first guide groove 12 and the second limiting groove 21. In the first direction, the first guide groove 12 cooperates with the first rotating shaft 61 for guidance. Under the guidance of the first guide groove 12, the first rotating shaft 61 can rotate relative to the first guide groove 12. Due to the contact and limitation between the first rotating shaft 61 and the second limiting groove 21, the bracket 2 can rotate together with the cross-rotating shaft 6, thereby realizing the rotation of the bracket 2 relative to the fixing base 1 in the first direction.

[0062] The cross-axis 6 is used to realize the rotational freedom in the first direction and the rotational freedom in the second direction between the bracket 2 and the fixing seat 1, so that the bracket 2 can rotate in two orthogonal directions, and the movements in the two orthogonal directions are relatively independent without crosstalk. Moreover, the processing technology of the first limiting groove 11, the second limiting groove 21, the first guide groove 12 and the second guide groove 22 is mature and the tolerance is small, which is also conducive to improving the production yield of the reflective component.

[0063] In some embodiments, the bracket 2 further includes at least one protrusion 23 extending toward the interior of the second limiting groove 21. The protrusion 23 can contact and limit the first rotating shaft 61. This reduces the contact area compared to limiting the position by full-surface contact between the first rotating shaft 61 and the second limiting groove 21. This reduces the friction between the first rotating shaft 61 and the second limiting groove 21 when the bracket 2 rotates about the second rotating shaft 62, thereby lowering the power requirement of the driving member 3. Furthermore, the limiting contact between the first rotating shaft 61 and the protrusion 23 can achieve relative fixation between the cross-rotating shaft 6 and the bracket 2, facilitating subsequent axial rotation of the bracket 2 along with the cross-rotating shaft 6 about the first rotating shaft 61. Optionally, the protrusion 23 can be symmetrically disposed on both sides of the second limiting groove 21. Alternatively, the protrusion 23 can be asymmetrically disposed on both sides of the second limiting groove 21. Alternatively, the protrusion 23 can be disposed on either side of the second limiting groove 21.

[0064] Furthermore, the bracket 2 may also include an air-avoidance groove, which is provided at the rear end of the convex portion 23 in the force-bearing direction, so that when the first rotating shaft 61 is assembled, the bracket 2 has good deformation performance, and the contact and fitting pressure between the first rotating shaft 61 and the convex portion 23 can be reduced, thereby reducing the friction force between the second limiting groove 21 and the first rotating shaft 61 that the bracket 2 needs to overcome when the bracket 2 rotates relative to the second rotating shaft 62. Optionally, the convex portion 23 can be a cylindrical convex portion, so that the cylindrical convex portion and the first rotating shaft 61 are in line contact through the provision of the cylindrical convex portion, and the friction force is very small, thereby reducing the friction force between the second limiting groove 21 and the first rotating shaft 61 that the bracket 2 needs to overcome.

[0065] In each of the above embodiments, the first guide groove 12 can be a groove-shaped structure that can cooperate with the outer circumferential surface of the first rotating shaft 61 for guidance. For example, the first guide groove 12 can include a groove bottom 121, and the groove bottom 121 includes a first inclined surface 122 and a second inclined surface 123. The first inclined surface 122 and the second inclined surface 123 are tangent to the first rotating shaft 61 respectively, so that the first inclined surface 122 and the second inclined surface 123 are in line contact, which is beneficial to reducing the friction force that the bracket 2 needs to overcome during the rotation relative to the first rotating shaft 61. Among them, the first inclined surface 122 and the second inclined surface 123 can intersect directly, or be connected by a transition inclined surface, a transition arc surface, or a transition bent surface. Optionally, the groove bottom 121 can also be an arc groove with a radius equal to that of the first rotating shaft 61, or the groove bottom 121 can be set as a combination of an inclined surface and a circular arc groove. The specific design can be as needed, and the present disclosure is not limited to this.

[0066] Similarly, the second guide groove 22 can be a groove-shaped structure that can cooperate with the outer peripheral surface of the second rotating shaft 62 for guidance. For example, the second guide groove 22 can include a groove bottom 221, and the groove bottom 221 includes a first inclined surface 222 and a second inclined surface 223, and the first inclined surface 222 and the second inclined surface 223 are respectively tangent to the second rotating shaft 62, so that the first inclined surface 222 and the second inclined surface 223 are in line contact, which is conducive to reducing the friction force that needs to be overcome during the rotation of the second rotating shaft 62 relative to the fixed seat 1. Among them, the first inclined surface 222 and the second inclined surface 223 can intersect directly, or be connected by a transition inclined surface, a transition arc surface, or a transition bent surface. Optionally, the groove bottom 221 can also be a circular arc groove with a radius equal to that of the second rotating shaft 62, or the groove bottom 221 can be set as a combination of an inclined surface and a circular arc groove. The specific design can be as needed, and the present disclosure is not limited to this.

[0067] In the above-mentioned embodiments, the first limiting groove 11 is a square groove with a width equal to the diameter of the second rotating shaft 62, so that the movement of the second rotating shaft 62 in the width direction of the first limiting groove 11 can be limited by the first limiting groove 11, and the friction between the second rotating shaft 62 and the first limiting groove 11 caused by tight fit is avoided, which is beneficial to reducing the friction force of the second rotating shaft 62 rotating in the first limiting groove 11 when the bracket 2 rotates with the first rotating shaft 61 relative to the first guide groove 12.

[0068] Similarly, the second limiting groove 21 is a square groove with a width equal to the diameter of the first rotating shaft 61, so that the second limiting groove 21 can limit the movement of the first rotating shaft 61 in the width direction of the second limiting groove 21, and avoid the tight fit that causes the friction between the first rotating shaft 61 and the second limiting groove 21 to be large, which is beneficial to reducing the friction of the first rotating shaft 61 rotating in the second limiting groove 21 when the bracket 2 rotates relative to the second guide groove 22.

[0069] Furthermore, the depth directions of the first guide groove 12 and the second limiting groove 21 are both perpendicular to the axial direction of the first rotating shaft 61, and the depth directions of the first guide groove 12 and the second limiting groove 21 are oppositely arranged. Figure 3 As shown, the depth direction of the first guide groove 12 and the second limiting groove 21 are both arranged along the direction indicated by arrow C, and the depth direction of the first guide groove 12 is downward along the direction indicated by arrow C, while the depth direction of the second limiting groove 21 is upward along the direction indicated by arrow C. Therefore, after the first rotating shaft 61 passes through the first guide groove 12 and the second limiting groove 21, the relative positional relationship between the first rotating shaft 61 and the second limiting groove 21 changes when the bracket 2 rotates about the axial direction of the second rotating shaft 62. Therefore, the bottom surface of the first guide groove 12 and the bottom surface of the second limiting groove 21 can cooperate to limit the end position of the travel of the bracket 2.

[0070] Similarly, the depth directions of the second guide groove 22 and the first limiting groove 11 are both perpendicular to the axial direction of the second rotating shaft 62, and the depth directions of the second guide groove 22 and the first limiting groove 11 are opposite. Figure 3 As shown, the depth direction of the second guide groove 22 and the first limiting groove 11 are both arranged along the direction indicated by arrow C, and the depth direction of the second guide groove 22 is downward along the direction indicated by arrow C, while the depth direction of the first limiting groove 11 is upward along the direction indicated by arrow C. Therefore, after the second rotating shaft 62 passes through the second guide groove 22 and the first limiting groove 11, when the cross-rotating shaft 6 and the bracket 2 rotate relative to the fixing base 1 around the axial direction of the second rotating shaft 62, the second rotating shaft 62 will also rotate accordingly, and thus the relative positional relationship between the second rotating shaft 62 and the first limiting groove 11 changes. Therefore, the bottom surface of the second guide groove 22 and the bottom surface of the first limiting groove 11 can cooperate to limit the end position of the travel of the bracket 2.

[0071] In some embodiments, as Figure 7 As shown, when the bracket 2 and the fixing seat 1 are in an initial position relationship, the first adsorption member 4 is located below the intersection of the first rotating shaft 61 and the second rotating shaft 62. For example, the bracket 2 may also include a sink 24 connected to both the second guide groove 22 and the first limiting groove 11, and the first adsorption member 4 may be arranged in the sink 24. For example, the first adsorption member 4 may be arranged in the sink 24 by bonding, snapping, or tight fitting. The axes of the first rotating shaft 61 and the second rotating shaft 62 may be located in the same plane, or in two parallel planes, and the specific design can be as needed, and the present disclosure does not limit this.

[0072] Based on the technical solution disclosed in this disclosure, Figures 8-10 As shown, the driving member 3 includes at least one set of electromagnetic components. Each set of electromagnetic components includes a coil mounted on the fixed base 1 and a magnet mounted on the bracket 2 and facing the coil. When the coil is energized, the magnet interacts with the coil to drive the bracket 2 to rotate in a first direction or a second direction at any time. For example, through the interaction between the coil and the magnet, the bracket 2 can be driven to rotate about the second rotation axis 62 at any time, or the bracket 2 and the cross-shaft 6 can be driven to rotate axially relative to the fixed base 1 about the first rotation axis 61.

[0073] Based on this, the bracket 2 is driven to move by cooperating with the coil and the magnet to realize the rotation of the bracket 2 relative to the fixed base 1. The structure is simple, and the force and rotation direction of the bracket 2 can be adjusted by adjusting the size and direction of the current loaded on the coil. The control is simple and the control accuracy is high.

[0074] In some embodiments, the reflective assembly may include a first electromagnetic assembly 31 and a second electromagnetic assembly 32, wherein the first electromagnetic assembly 31 includes a first coil 311 and a first magnet 312, and the second electromagnetic assembly 32 includes a second coil 321 and a second magnet 322, and the magnetic poles of the first magnet 312 and the second magnet 322 are arranged in the same direction. For example, Figure 10 As shown, the magnetic poles of the first magnet 312 and the second magnet 322 are arranged in the direction of Figure 10 The first coil 311 and the second coil 321 are arranged in parallel in the vertical direction, with the S pole at the top and the N pole at the bottom. The axial directions of the first coil 311 and the second coil 321 are both perpendicular to the magnetic pole arrangement direction of the first magnet 312 and the second magnet 322.

[0075] In which, the first coil 311 and the second coil 321 are arranged side by side and located on both sides of the rotation axis of any rotational degree of freedom of the bracket 2. When the first magnet 312 and the second magnet 322 are subjected to forces in opposite directions, the bracket 2 rotates around the rotation axis of any rotational degree of freedom; when the first magnet 312 and the second magnet 322 are subjected to forces in the same direction, the bracket 2 rotates around the rotation axis of another rotational degree of freedom that is perpendicular to the rotation axis of any rotational degree of freedom.

[0076] For example, taking the bracket 2 having the degree of freedom of rotation around the rotation axis of the first rotation axis 61 and the degree of freedom of rotation around the second rotation axis 62, the first coil 311 and the second coil 321 are located on both sides of the second rotation axis 62. Figure 9 As shown, when the first magnet 312 and the second magnet 322 are subjected to forces in the same direction, the bracket 2 rotates around the axis of the first rotating shaft 61 under the action of the forces; Figure 10 As shown, when the first magnet 312 and the second magnet 322 are subjected to forces in opposite directions, the bracket 2 rotates around the second rotation axis 62 under the action of the two opposite forces. The direction of the force between the first magnet 312 and the second magnet 322 can be adjusted by adjusting the direction of the current in the first coil 311 and the second coil 321, and the magnitude of the force can be adjusted by adjusting the magnitude of the current in the first coil 311 and the second coil 321.

[0077] Of course, the above embodiment is merely an example. In other embodiments, three or more sets of electromagnetic components may be provided, and one or more sets of electromagnetic components may be provided on either side of the second rotating shaft 62. Of course, in other embodiments, the multiple sets of electromagnetic components may also be distributed on both sides of the first rotating shaft 61.

[0078] In each of the above examples, the reflective component may further include a circuit board 7, the coil of each electromagnetic component may be electrically connected to the circuit board 7, the fixing base 1 may include a through-hole 13, the circuit board 7 may be connected to the fixing base 1 and cover at least a portion of the through-hole 13, and multiple coils may interact with the magnet through the same through-hole 13, or interact with the magnet through respective through-holes 13 arranged corresponding to each coil.

[0079] Furthermore, the reflective component may also include a position sensor 8, which may be fixed relative to the fixing base 1. For example, the position sensor 8 may be provided on the circuit board 7 to achieve relative fixation with the fixing base 1; or the position sensor 8 may also be provided on another corresponding circuit board and fixed relative to the fixing base 1 via the circuit board. The position sensor 8 may be used to output an electrical signal for determining the position information of the bracket 2. Optionally, the position sensor 8 may include a Hall sensor, which may be used to sense the positions of the first magnet 312 and the second magnet 322, and then output an electrical signal for determining the position information of the bracket 2. For example, the reflective component may include two Hall sensors, which are respectively provided corresponding to the first magnet 312 and the second magnet 322. In this way, the first magnet 312 and the second magnet 322 may be sensed by the two Hall sensors, respectively, and the position information of the bracket may be determined by the electrical signals output by the two Hall sensors, which is conducive to obtaining the position information of the bracket 2 in real time and facilitating the determination of the anti-shake condition.
