Abstract
Description
Technical Field

[0002] At present, the existing anti-shake motor structures of periscope anti-shake modules can be mainly divided into two categories; the first category uses multiple planar springs, which are non-conductive and serve as elastic reset parts. The movable structure and the immovable structure are suspended by springs, and the movable structure is equipped with a driving magnet, and the immovable structure is equipped with a coil. After the coil is energized, the corresponding magnet pushes the movable structure to achieve the anti-shake effect; the springs of this type of anti-shake motor are connected to the fixed seat parallel to or perpendicular to the rotating shaft, and the fixed position of the spring is far away from the rotating shaft, and the displacement spring coefficient is low, the reliability and impact resistance are poor, and the poor posture can seriously affect the anti-shake effect; in addition, the driving magnet is on the movable structure, the mass of the movable structure increases, and the power consumption will also increase; because the magnet is in the movable structure, the magnet in the movable structure is easily attracted and interfered by the nearby magnets, resulting in poor anti-shake performance;
[0003] The second type uses a spring-loaded structure equipped with a ball or a structural convex hull to support the movable structure and the stationary structure as a fulcrum, and the movable structure and the stationary structure connected by the spring are reset, and the magnet is installed on the movable structure, and the stationary structure is installed with a coil. After the coil is energized, the corresponding magnet pushes the movable structure to achieve an anti-shake effect; the fulcrum of this type of design produces nonlinear friction during the anti-shake movement, which affects the anti-shake effect, increases power consumption, and causes noise; after working for a long time, the fulcrum wears due to long-term friction, resulting in a decrease in anti-shake performance; the movable structure contains a magnet, and the magnet in the movable structure is easily attracted and disturbed by nearby magnets; the structure uses balls and structural fulcrums to contact, and the reliability and impact resistance are poor, which will cause nonlinear friction after the reliability, resulting in poor anti-shake performance and noise during anti-shake movement.
[0004] The above two types of anti-shake motors are affected by magnetic interference when the end customer modules are stacked. They need to be stacked with other motor modules at a distance to avoid the magnetic interference problem, which is not conducive to compact arrangement and stacking, and takes up space.

[0064] Example 1
[0065] like Figure 1-Figure 5 As shown, this embodiment provides a magnetostatic reflective anti-shake motor 100 , which is a closed-loop anti-shake control structure.
[0066] It should be noted that, for ease of description, the external dimensions of the magnetostatic reflective anti-shake motor 100 are L, W, and T, respectively, satisfying: L ≥ W ≥ T. The maximum external dimensions or minimum external dimensions of the magnetostatic reflective anti-shake motor 100 described below refer to the selection among the length L, width W, and height T.
[0067] Please combine Figure 1-Figure 5 It is understood that the magnetostatic reflective anti-shake motor 100 of this embodiment includes at least one stationary structure, at least one movable structure and at least one connecting component.
[0068] In a specific embodiment, the stationary structure includes at least one fixed bracket 113 and at least one magnet group. The magnet group includes at least one magnet 117. The magnet 117 is arranged at the end of the fixed bracket 113. The stationary structure is formed by arranging the magnet 117 on the fixed bracket 113, which reduces the mass of the movable structure and reduces the power consumption of the movable structure. In addition, since the magnet 117 is in the stationary structure, the magnet 117 is not easily attracted or disturbed by nearby magnets 117, thereby improving the anti-shake effect.
[0069] In some embodiments, the movable structure can rotate around a rotation center 121, and the movable structure includes at least one movable support 115, at least one coil 118, at least one position sensor 119 and at least one reflection component 120. In a preferred embodiment, the magnet group includes a magnet 117, and the movable structure includes a movable support 115, a coil 118, a position sensor 119 and a reflection component 120. The reflection component 120 is connected to the movable support 115, and the coil 118 and the position sensor 119 are both arranged at the end of the movable support 115, and the coil 118 and the position sensor 119 are respectively arranged opposite to the magnet 117. In this way, the coil 118 and the position sensor 119 share a magnet 117, which can reduce manufacturing costs.
[0070] In some embodiments, the connecting component connects at least one fixed structure and at least one movable structure; the connecting component includes at least one elastic component 114 and at least one first circuit board 116. In a preferred embodiment, the elastic component 114 and the first circuit board 116 are each one, the elastic component 114 is connected to the fixed structure and the movable structure, the first circuit board 116 is connected to the fixed structure and the movable structure, the coil 118 is electrically connected to the first circuit board 116 or the elastic component 114, and the position sensor 119 is electrically connected to the first circuit board 116; wherein, when the coil 118 is energized, it can push the movable structure to rotate around the rotation center 121.
[0071] Exemplarily, the elastic component 114 is connected between the fixed bracket 113 and the movable bracket 115 , and the first circuit board 116 is also connected between the fixed bracket 113 and the movable bracket 115 .
[0072] In this way, this embodiment sets a connecting component between the movable structure and the fixed structure, and utilizes the elastic component 114 and the first circuit board 116 to improve the elastic coefficient of the entire connecting component, enhance the impact resistance, and effectively avoid the influence of the anti-shake effect due to the existing spring clip posture difference.
[0073] Exemplarily, in order to facilitate the assembly of the fixed structure, the movable structure and the connecting components in the shell 111, the shell 111 includes a first shell 111a and a second shell 111b, and the shell 111 is arranged into two parts, so that the static magneto-reflective anti-shake motor 100 can be more flexible and convenient during assembly, thereby improving production efficiency and reducing production costs.
[0074] In some embodiments, a gap is provided between the movable structure and the stationary structure, and a connecting component acts between the movable structure and the stationary structure so that there is no direct contact between the two. The advantage is that there is a gap between the movable structure and the stationary structure, and the anti-shake operation of the movable structure does not interfere with the stationary structure, and no nonlinear friction occurs during the anti-shake movement, thereby avoiding affecting the anti-shake effect and causing noise.
[0075] In some embodiments, the shell 111 has an incident window and a reflection window, and the reflection component 120 is provided with a reflection surface, which is used to reflect at least one incident light beam passing through the incident window to the reflection window and output at least one reflected light beam; in other embodiments, the directions of the incident window and the reflection window are perpendicular to each other.
[0076] In some embodiments, the reflective component 120 is a prism or a reflective lens. The use of a prism has high-precision color reproduction, excellent spectral sensitivity characteristics, and high spatial resolution, so that the static magneto-reflective anti-shake motor 100 performs better. In other embodiments, the reflective component 120 is preferably a prism, and the reflective lens can be any lens available on the market.
[0077] like Figure 5 As shown, in some embodiments, the first circuit board 116 includes at least one first fixed portion 116a, at least one second fixed portion 116b and at least one first deformable portion 116c, the first fixed portion 116a is connected to the movable structure; the second fixed portion 116b is connected to the fixed structure; the first deformable portion 116c is connected between the first fixed portion 116a and the second fixed portion 116b, and the first deformable portion 116c is a flexible circuit board. The shape of the first deformable portion 116c can be a straight line or an arc, or a wave shape, and the shape of the deformable portion can be adjusted according to different structures to avoid interference with the fixed structure, and the first deformable portion 116c can be twisted and deformed when the movable structure moves.
[0078] In the above embodiment, by providing a first circuit board 116 that can generate deformation, in cooperation with the elastic component 114, the elastic coefficient of the entire connecting component can be increased, the impact resistance can be improved, and the anti-shake effect can be effectively avoided due to the difference in the posture of the spring fragment. No nonlinear friction will occur during the anti-shake movement, and noise can be avoided.
[0079] Further preferably, the first deformation portion 116c is provided with a center line 116d extending from the first fixed portion 116a to the second fixed portion 116b, and the length R of the center line 116d is greater than 1 / 3 of the minimum external dimension of the static magneto-reflective anti-shake motor 100, that is, greater than 1 / 3 of the height T of the static magneto-reflective anti-shake motor 100.
[0080] Further preferably, the minimum width of the first deformation portion 116c is Q, and the length R of the center line 116d satisfies: R>10Q, thereby preventing the first deformation portion 116c from interfering with the immovable structure when the movable structure moves.
[0081] In some embodiments, the elastic component 114 includes at least four spring pieces, each of which includes at least one third fixed portion 114a, at least one fourth fixed portion 114b and at least one second deformable portion 114c; the third fixed portion 114a is connected to the movable structure; the fourth fixed portion 114b is connected to the immovable structure; the second deformable portion 114c is connected between the third fixed portion 114a and the fourth fixed portion 114b. In a specific embodiment, the third fixed portion 114a is connected to the movable bracket 115, and the fourth fixed portion 114b is connected to the fixed bracket 113; in a specific embodiment, the second deformable portion 114c of each spring piece is tilted between the movable structure and the immovable structure.
[0082] In the above-mentioned embodiment, by using multiple inclined spring pieces between the movable structure and the stationary structure, the second deformation portion 114c of each spring piece is in a plane, and the multiple spring pieces are arranged to be gradually contracted from the stationary structure toward the movable structure, which can further improve the elastic coefficient of the entire connecting assembly, enhance the impact resistance, and effectively avoid the impact of the anti-shake effect due to the difference in the posture of the spring pieces. In addition, the present invention does not need to set up ball bearings or structural convex hull supports, and no nonlinear friction will occur during the anti-shake movement, thus avoiding noise.
[0083] In other embodiments, components with the same properties and functions as the spring fragments may be used to replace the spring fragments. For ordinary technicians in this technical field, several improvements and substitutions may be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be regarded as the scope of protection of the present invention.
[0084] In some embodiments, the planes where the second deformation portions 114c of at least three spring clips are located intersect to form an intersection F. It should be noted that this embodiment preferably uses four spring clips. Since the four planes where the four spring clips are located, each three planes extend to intersect at a point F, multiple points will appear. Therefore, the distance between the intersection F and the rotation center 121 is limited to less than 1 / 5 of the minimum external dimension of the static magneto-reflective anti-shake motor 100, that is, less than 1 / 5 of the height T of the static magneto-reflective anti-shake motor 100.
[0085] In some embodiments, the magnetostatic reflective anti-shake motor 100 further includes a second circuit board 112, and the second circuit board 112 is electrically connected to the first circuit board 116, the coil 118, and the position sensor 119, respectively. In another embodiment, the second circuit board 112 is electrically connected to the first circuit board 116 and the position sensor 119, and the second circuit board 112 is electrically connected to the coil 118 through the elastic component 114. In this way, a variety of circuit series schemes can be adopted according to the design and production needs, which can reduce the manufacturing cost in actual production. Specifically, the second circuit board 112 can be connected to the external circuit to be electrically connected to the first circuit board 116, the coil 118, and the position sensor 119; or, the second circuit board 112 can be connected to the external circuit to be electrically connected to the first circuit board 116 and the position sensor 119, and the second circuit board 112 can be electrically connected to the coil 118 through the elastic component 114.
[0086] In some embodiments, the position sensor 119 may be a Hall sensor or a tunnel magnetoresistive effect sensor. All position sensors 119 are located away from at least one rotation center 121 (the distance between the position sensor 119 and the rotation center 121 is greater than 1 / 5 of the longest side L of the magnetostatic reflective anti-shake motor 100).
[0087] Example 2
[0088] The difference between the second embodiment and the first embodiment is that the second embodiment provides a static magneto-reflective anti-shake motor 100 , which is a closed-loop control anti-shake structure.
[0089] like Figure 6-Figure 7 As shown, the static magneto-reflective anti-shake motor 100 of this embodiment includes at least one stationary structure, at least one movable structure and at least one connecting component.
[0090] In a specific embodiment, the stationary structure includes at least one fixed bracket 113 and at least one magnet group. The magnet group includes at least two magnets 117. The magnets 117 are arranged on both side ends of the fixed bracket 113. By arranging the magnets 117 on the fixed bracket 113 to form a stationary structure, the mass of the movable structure is reduced, and the power consumption of the movable structure is reduced. Since the magnets 117 are in the stationary structure, the magnets 117 are not easily attracted or disturbed by nearby magnets 117, thereby improving the anti-shake effect.
[0091] In some embodiments, the movable structure can rotate around a rotation center 121, and the movable structure includes at least one movable support 115, at least two coils 118, at least two position sensors 119 and at least one reflection component 120. In a preferred embodiment, the magnet group includes two magnets 117, and the movable structure includes a movable support 115, two coils 118, two position sensors 119 and a reflection component 120. The reflection component 120 is connected to the movable support 115, and the coils 118 and the position sensors 119 are both arranged at the end of the movable support 115. Each position sensor 119 is arranged opposite to one of the magnets 117, and each coil 118 is arranged opposite to one of the magnets 117; in this way, the coils 118 and the position sensors 119 share one magnet 117, which can reduce manufacturing costs.
[0092] In some embodiments, the connecting component connects at least one fixed structure and at least one movable structure; the connecting component includes at least one elastic component 114 and at least two first circuit boards 116. In a preferred embodiment, there is one elastic component 114 and two first circuit boards 116, wherein one coil 118 is electrically connected to one of the first circuit boards 116 or the elastic component 114, and one position sensor 119 is electrically connected to one of the first circuit boards 116; wherein, when the coil 118 is energized, it can push the movable structure to rotate around the rotation center 121.
[0093] This embodiment uses at least two magnets 117, at least two coils 118, at least two position sensors 119 and at least two first circuit boards 116, which can be arranged at two ends of the moving bracket 115 in a relative manner, thereby further improving the anti-shake effect.

Moreover, since the magnets 117 are in the fixed structure, the magnets 117 are not easily attracted and disturbed by the nearby magnets 117, thereby improving the anti-shake effect.
[0097] In some embodiments, the movable structure can rotate around a rotation center 121, and the movable structure includes at least one movable support 115, at least two coils 118, at least two position sensors 119 and at least one reflection component 120. In a preferred embodiment, the magnet group includes two magnets 117, and the movable structure includes a movable support 115, two coils 118, two position sensors 119 and a reflection component 120. The reflection component 120 is connected to the movable support 115, and the coils 118 and the position sensors 119 are both arranged at the end of the movable support 115. Each position sensor 119 is arranged opposite to one of the magnets 117, and each coil 118 is arranged opposite to one of the magnets 117; in this way, the coils 118 and the position sensors 119 share one magnet 117, which can reduce manufacturing costs.
[0098] In some embodiments, the connecting component connects at least one fixed structure and at least one movable structure; the connecting component includes at least one elastic component 114 and at least one first circuit board 116.

[0109] In summary, the embodiment of the present invention provides a static magneto-reflective anti-shake motor 100 and a periscope module, which reduces the mass of the movable structure and the power consumption of the movable structure by setting a magnet group on a fixed bracket 113 to form a fixed structure. Moreover, since the magnet group is in the fixed structure, the magnet group is not easily attracted or disturbed by the nearby magnet 117, thereby improving the anti-shake effect. In addition, a connecting component is set between the movable structure and the fixed structure, and the elastic component 114 and the first circuit board 116 can be used to improve the elastic coefficient of the entire connecting component, improve the impact resistance, and effectively avoid the existing spring element posture difference affecting the anti-shake effect. Moreover, the present invention does not need to set a ball or structural convex support, and no nonlinear friction will occur during the anti-shake movement, thereby avoiding noise. The present invention adopts a connecting component to make the movable structure have a suspension design, and the magnet group is set in the fixed structure, which can better prevent external magnetic interference to the product, reduce noise, and effectively improve the anti-shake effect. Moreover, since the magnet group is not easily attracted or disturbed by the nearby magnet 117, the stacking spacing of the terminal modules can be reduced, making the terminal modules more compact. The present invention has a simpler structure and can better improve production efficiency and reduce production costs.
