Abstract
Description
Technical Field
[0001] Embodiments of this application relate to the technical field of cameras, and more particularly to a motor, camera module, and electronic device. Background Technology
[0002] Electronic devices typically include a camera module, which can acquire image information, enabling electronic devices to perform functions such as taking pictures, recording videos, and image information recognition.
[0003] The camera module includes a motor and a lens. The motor comprises a frame, a carrier, and a guide structure. The carrier is connected to the lens and can move relative to the frame along the optical axis of the lens, thereby driving the lens to move along the optical axis and enabling the camera module to achieve autofocus. The guide structure is positioned between the carrier and the frame, guiding and limiting the movement of the carrier.
[0004] During the movement of the carrier relative to the frame, it is easy for it to separate from the guide structure, causing the carrier to flip relative to the frame and affecting the reliability of the carrier's movement. Summary of the Invention
[0005] Embodiments of this application provide a motor, camera module, and electronic device that can reduce the risk of separation between the carrier and the guide structure, thereby improving the motion reliability of the carrier.
[0006] On one hand, embodiments of this application provide a motor. The motor includes a frame, a carrier, a guide structure, a first coil, a first magnet, and an elastic element. The carrier is used to support a lens and is movably disposed within the frame. The carrier can move relative to the frame along the optical axis of the lens. The carrier includes four corners arranged in an array along a first direction and a second direction, which are perpendicular to each other. The guide structure is disposed on the side of the frame near the carrier and connected to the frame. The carrier and the guide structure are movably connected. The guide structure includes a first guide structure and a second guide structure. The first guide structure is adjacent to one corner, and the second guide structure is adjacent to another corner. One of the first coil and the first magnet is connected to the carrier, and the other is connected to the frame. The first coil and the first magnet are arranged radially opposite each other along the carrier. When the first coil is energized, a first driving force is generated between the first coil and the first magnet. The first driving force is used to drive the carrier to move relative to the frame along the optical axis of the lens. The elastic element includes a first body portion and a second body portion. The first body portion is connected to the frame. The second body portion is connected to the carrier. A deformation portion connects the first body portion and the second body portion. The deformation section is used to pre-deform, so that the deformation section applies an elastic preload to the carrier. When the first guide structure and the second guide structure are respectively arranged adjacent to two corners located on the diagonal of the carrier, the elastic preload acts on the carrier and points towards the first guide structure in a clockwise or counterclockwise direction, so that the carrier and the first guide structure fit together. When the first guide structure and the second guide structure are respectively arranged adjacent to two corners located on one side of the carrier, the elastic preload acts on the carrier and points towards the first guide structure in the direction from the carrier to the frame, so that the carrier and the first guide structure fit together.
[0007] In some possible implementations, there are multiple elastic elements, which are spaced apart circumferentially along the carrier. The deformation portions of each elastic element have a pre-deformation capacity, and the deformation portions of each elastic element provide a sub-elastic preload to the carrier. The resultant force of the multiple sub-elastic preloads is the elastic preload.
[0008] In some possible implementations, a first groove is provided on the carrier, a second groove is provided on the frame, the first groove and the second groove are arranged opposite to each other to form a limiting cavity, and a second guide structure is provided in the limiting cavity.
[0009] In some possible implementations, the first groove is a V-shaped groove and the second groove is a U-shaped groove.
[0010] In some possible implementations, a third groove is provided on the frame, and the carrier includes an abutment surface, with the abutment surface and the third groove positioned opposite each other. Along the circumference of the first guide structure, a portion of the first guide structure is located within the third groove, and another portion abuts against the abutment surface.
[0011] In some possible implementations, the carrier has a first receiving groove, and the first receiving groove and the second guide structure are arranged adjacent to each other. The motor also includes a second magnet located in the first receiving groove, and the second magnet is used to attract the second guide structure.
[0012] In some possible implementations, when the first coil is de-energized, the deformable part is used to apply a first reset force to the carrier, and the carrier is reset under the action of the first reset force.
[0013] In some possible implementations, the guide structure includes guide posts.
[0014] On the other hand, embodiments of this application provide a camera module. The camera module includes a lens and a motor as described above, with the lens and motor connected to a carrier.
[0015] In another aspect, embodiments of this application provide an electronic device. The electronic device includes a housing and a camera module as described above, with at least a portion of the camera module disposed within a receiving space enclosed by the housing.
[0016] In summary, the embodiments of this application have at least the following beneficial effects:
[0017] In the embodiments of this application, the deformation part is pre-deformed to apply an elastic pre-tightening force to the carrier. The carrier can fit with the first guide structure under the action of the elastic pre-tightening force, which reduces the risk of separation between the carrier and the first guide structure. This allows the first guide structure to guide and limit the movement of the carrier relative to the frame, reducing the risk of the carrier flipping relative to the frame and improving the reliability of the carrier's movement.
[0018] Furthermore, by applying an elastic preload to the carrier using a deformable part, the carrier and the first guide structure are brought into contact, eliminating the need for structures such as magnets to hold the first guide structure in place. This simplifies the motor's structure, improves production efficiency, and reduces costs. Additionally, it eliminates the need for grooves on the carrier to accommodate the magnets holding the first guide structure in place, thus enhancing the carrier's mechanical strength.
[0019] Furthermore, the deformation section can apply elastic preload to the carrier in different directions to adapt to the different positions of the first guide structure and the second guide structure, thus meeting the needs under different conditions. Attached Figure Description

[0039] Figure 1 These are schematic diagrams illustrating the structure of electronic devices provided in some embodiments of this application. For example... Figure 1 As shown, an embodiment of this application provides an electronic device 300. The electronic device 300 can be a smartphone, smartwatch, smart bracelet, laptop, tablet, etc., and the embodiments of this application do not further limit the specific form of the electronic device 300.
[0040] Continue to refer to Figure 1 In some examples, electronic device 300 may include housing 310 and camera module 200, at least a portion of which is disposed within a receiving space enclosed by housing 310.
[0041] Understandably, the camera module 200 is used to acquire image information, enabling the electronic device 300 to perform functions such as taking pictures, recording videos, and image information recognition. At least a portion of the camera module 200 is disposed within the receiving space enclosed by the housing 310, so that the housing 310 can protect the camera module 200.
[0042] The electronic device 300 may include one camera module 200 or multiple camera modules 200. The camera module 200 may be a front-facing camera or a rear-facing camera of the electronic device 300.

[0043] The electronic device 300 may also include a display panel (not shown in the figure), which is connected to the housing 310 and is used to display image information. The display panel may be at least one of a liquid crystal display (LCD) panel or an organic light-emitting diode (OLED) panel, and the embodiments of this application do not further limit the specific form of the display panel.
[0044] Figure 2 This is an exploded view of a camera module provided in some embodiments of this application. In some examples, such as... Figure 2 As shown, the camera module 200 includes a lens 210 and a motor 100, with the motor 100 connected to the lens 210. The motor 100 is used to drive the lens 210 to move, enabling the camera module 200 to achieve automatic focus (AF) and optical image stabilization (OIS).
[0045] For example, lens 210 may include at least one of a convex lens, a concave lens, and other optical lenses. Embodiments of this application do not further limit lens 210; the motor 100 is described below as an example.
[0046] Figure 3 for Figure 2 The diagram shows the exploded structure of the motor in some embodiments. Figure 4 for Figure 2 The diagram shows the exploded structure of the motor in some other embodiments.
[0047] In some examples, such as Figure 3 and Figure 4 As shown, the motor 100 includes a frame 110, a carrier 120, and a guide structure 130.
[0048] The carrier 120 is used to support the lens 210. The carrier 120 is movably disposed within the frame 110 and can move relative to the frame 110 along the optical axis of the lens 210. For example, the frame 110 can surround the carrier 120 and be movably connected to the carrier 120, so that the carrier 120 can move relative to the frame 110 along the optical axis Z.
[0049] Understandably, the lens 210 is connected to the carrier 120. When the carrier 120 moves relative to the frame 110 along the optical axis Z, it can drive the lens 210 to move relative to the frame 110 along the optical axis Z, so that the camera module 200 can achieve autofocus.
[0050] In some examples, such as Figure 3 As shown, the guide structure 130 is disposed on the side of the frame 110 near the carrier 120 and connected to the frame 110, and the carrier 120 and the guide structure 130 are movably connected.
[0051] Understandably, the guide structure 130 is located between the frame 110 and the carrier 120. The carrier 120 and the guide structure 130 are movably connected, allowing the carrier 120 to be movably connected to the frame 110 via the guide structure 130. The guide structure 130 can guide and limit the movement of the carrier 120 relative to the frame 110 along the optical axis Z, thereby improving the reliability of the movement of the carrier 120.
[0052] In some examples, such as Figure 4 As shown, the guide structure 130 includes a guide post, which can be a cylindrical structure, or it can be a prism or other columnar structure.
[0053] The guide post and the frame 110 can be fixedly connected, and the carrier 120 and the guide post can be slidably connected, so that the carrier 120 can be slidably connected to the frame 110 through the guide post, thereby enabling the carrier 120 to move relative to the frame 110 along the optical axis Z.
[0054] Understandably, the guide structure 130 includes guide posts, eliminating the need for a complex structure, which simplifies the structure of the motor 100 and reduces its cost.
[0055] In other examples, the guide structure 130 may also include guide balls (not shown in the figure), and the number of guide balls may be multiple, with the multiple guide balls arranged along the optical axis direction Z.
[0056] The guide ball and the frame 110 can be rolled together, and the carrier 120 and the guide ball can also be rolled together, so that the carrier 120 can be movably connected to the frame 110 through the guide ball, thereby enabling the carrier 120 to move relative to the frame 110 along the optical axis Z.
[0057] Understandably, the guide structure can also be other structures besides guide posts and guide balls. The embodiments of this application do not further limit the specific form of the guide structure 130.
[0058] In some examples, the carrier 120 includes four corners 122 arranged along a first direction X and a second direction Y, and the four corners 122 are arranged in an array along the first direction X and the second direction Y. The second direction Y is perpendicular to the first direction X. For example, the second direction Y and the first direction X can be perpendicular or approximately perpendicular, that is, the angle between the second direction Y and the first direction X can be 90°, 88°, or 89°, etc.
[0059] Understandably, angle 122 refers to the corner of carrier 120. For example, as shown... Figure 4 As shown, the four edges 122 may include a first edge 1221, a second edge 1222, a third edge 1223 and a fourth edge 1224. The first edge 1221 and the second edge 1222 are spaced apart along the first direction X. The third edge 1223 is disposed on one side of the first edge 1221 along the second direction Y. The fourth edge 1224 is disposed on one side of the second edge 1222 along the second direction Y.
[0060] Alternatively, the first edge 1221, the second edge 1222, the third edge 1223, and the fourth edge 1224 can also be arranged in other ways, and the embodiments of this application do not further limit this.
[0061] Continue to refer to Figure 3 and Figure 4 In some examples, the guide structure 130 may include a first guide structure 131 and a second guide structure 132. Understandably, the first guide structure 131 and the second guide structure 132 may have the same shape and structure or they may be different.
[0062] The first guide structure 131 is arranged adjacent to one edge 122, and the second guide structure 132 is arranged adjacent to another edge 122.
[0063] For example, one of the first guide structure 131 and the second guide structure 132 can be arranged adjacent to the first corner 1221, and the other can be arranged adjacent to the fourth corner 1224. In this case, the first guide structure 131 and the second guide structure 132 are arranged adjacent to each other along the diagonal of the carrier 120.
[0064] Alternatively, one of the first guide structure 131 and the second guide structure 132 can be arranged adjacent to the first corner 1221, and the other can be arranged adjacent to the second corner 1222 or the third corner 1223. In this case, the first guide structure 131 and the second guide structure 132 can be arranged on the same side of the carrier 120 along the first direction X, or they can be arranged on the same side of the carrier 120 along the second direction Y.
[0065] Understandably, the first guide structure 131 is arranged adjacent to one edge 122, and the second guide structure 132 is arranged adjacent to another edge 122, so that the first guide structure 131 and the second guide structure 132 can be arranged opposite each other along the diagonal of the carrier 120, or the first guide structure 131 and the second guide structure 132 can be arranged on the same side of the carrier 120, which improves the flexibility of the arrangement of the first guide structure 131 and the second guide structure 132 and meets the usage requirements under different conditions.
[0066] Figure 5 The diagram shows the structure of a motor provided in some embodiments of this application. Figure 6 for Figure 5 A magnified schematic diagram of the local structure of region D1. Figure 7 for Figure 5 A magnified schematic diagram of the local structure of region D2.
[0067] In some examples, such as Figure 5 and Figure 7 As shown, a third groove P3 is provided on the frame 110, and the carrier 120 includes an abutment surface 121, which is disposed opposite to the third groove P3. Along the circumference of the first guide structure 131, a part of the first guide structure 131 is located in the third groove P3, and another part abuts against the abutment surface 121.
[0068] Understandably, the third groove P3 can limit the first guide structure 131 to reduce the risk of the first guide structure 131 shifting relative to the frame 110 and the carrier 120.
[0069] In some examples, such as Figure 5 and Figure 6 As shown, a first groove P1 is provided on the carrier 120, and a second groove P2 is provided on the frame 110. The first groove P1 and the second groove P2 are arranged opposite to each other to form a limiting cavity, and the second guide structure 132 is provided in the limiting cavity.
[0070] Understandably, the limiting cavity can limit the second guide structure 132 to reduce the risk of the second guide structure 132 shifting relative to the frame 110 and the carrier 120.
[0071] Continue to refer to Figure 6 In some examples, the first groove P1 is a V-shaped groove and the second groove P2 is a U-shaped groove.
[0072] This configuration improves the limiting effect of the limiting cavity on the second guide structure 132 and enhances the motion reliability of the carrier 120.
[0073] Figure 8 for Figure 2A schematic cross-sectional view of the motor along the A1-A1 direction. In some examples, such as... Figure 8 As shown, the motor 100 also includes a first coil 141 and a first magnet 142. One of the first coil 141 and the first magnet 142 is connected to the carrier 120, and the other is connected to the frame 110. The first coil 141 and the first magnet 142 are arranged opposite each other along the radial direction of the carrier 120.
[0074] When the first coil 141 is energized, a first driving force is generated between the first coil 141 and the first magnet 142. The first driving force is used to drive the carrier 120 to move relative to the frame 110 along the optical axis Z of the lens 210.
[0075] Understandably, the first coil 141 generates a magnetic field when energized. The first coil 141 and the first magnet 142 are arranged radially opposite each other along the carrier 120. When the first coil 141 is energized, the magnetic field generated by the first coil 141 and the magnetic field of the first magnet 142 interact to generate a first driving force. This first driving force drives the carrier 120 to move relative to the frame 110 along the optical axis Z, enabling the camera module 200 to achieve autofocus.
[0076] The magnitude of the first driving force can be changed by altering the current flowing through the first coil 141. The direction of the first driving force can be changed by altering the direction of the current flowing through the first coil 141.
[0077] When the first coil 141 is connected to the carrier 120 and the first magnet 142 is connected to the frame 110, the carrier 120 can drive the first coil 141 to move relative to the frame 110 along the optical axis direction Z. At this time, the motor 100 is a moving coil type.
[0078] When the first coil 141 is connected to the frame 110 and the first magnet 142 is connected to the carrier 120, the carrier 120 can drive the first magnet 142 to move relative to the frame 110 along the optical axis direction Z. At this time, the motor 100 is a moving magnet type.
[0079] The embodiments of this application take the connection of the first coil 141 and the carrier 120, the connection of the first magnet 142 and the frame 110, and the motor 100 as a moving coil as an example, and will continue to illustrate with examples.
[0080] For example, there can be two first coils 141. The two first coils 141 can be arranged on both sides of the carrier 120 along the second direction Y (or the first direction X) and connected to the carrier 120 respectively.
[0081] The number of first magnets 142 can be multiple. Multiple first magnets 142 can be disposed on both sides of the carrier 120 along the second direction Y (or the first direction X) and respectively connected to the frame 110. For example, ... Figure 8 As shown, two first magnets 142 and one first coil 141 can be arranged opposite each other, and the two first magnets 142 can be arranged adjacent to each other along the optical axis direction Z.
[0082] By adopting the above configuration, the first coil 141 and the first magnet 142 can provide two driving forces for the carrier 120, and the two first driving forces act on both sides of the carrier 120 along the second direction Y, thereby improving the motion reliability of the carrier 120.
[0083] Refer again Figure 3 and Figure 4 In some examples, the motor 100 also includes a top cover 180 and a base 160. The top cover 180 includes a cover plate 181 and a side wall 182. The cover plate 181 is located on one side of the frame 110 and the carrier 120 along the optical axis Z. The side wall 182 surrounds the frame 110 and the carrier 120 and is connected to the cover plate 181. For example, the side wall 182 and the cover plate 181 can be an integrally formed structure to improve the reliability of their connection.
[0084] A receiving hole E may be provided on the cover plate 181, and the receiving hole E penetrates the cover plate 181 along the thickness direction. The receiving hole E is used to receive the lens 210.
[0085] Continue to refer to Figure 3 and Figure 4 In some examples, the motor 100 also includes a base 160, which includes a base plate 161 and a plurality of extensions 162. The base plate 161 is located on the side of the frame 110 and the carrier 120 away from the cover plate 181 along the optical axis Z, and the base plate 161 is connected to the side wall 182. In this way, the base plate 161 and the cover 180 can form a receiving cavity, in which the frame 110 and the carrier 120 are located, thereby protecting the frame 110 and the carrier 120.
[0086] The extension 162 extends along the optical axis direction Z, and multiple extensions 162 are respectively connected to the base plate 161, and multiple extensions 162 are arranged at intervals along the circumference of the base plate 161.
[0087] For example, the extension 162 and the base plate 161 can be an integrally formed structure to improve the reliability of their connection. Multiple extensions 162 are connected to the base plate 161 and are spaced apart circumferentially along the base plate 161. The frame 110 and the carrier 120 are located within the receiving cavity enclosed by the base plate 161 and the top cover 180, allowing the multiple extensions 162 to surround the frame 110 circumferentially, thus limiting the position of the frame 110 and the carrier 120.
[0088] The number of extensions 162 can be four, or it can be three, five or more. The embodiments of this application do not further limit the number of extensions 162.
[0089] Figure 9 This is a schematic diagram showing the positional relationship between the base, ball bearing, second coil, and third coil provided in some embodiments of this application.
[0090] In some examples, such as Figure 9 As shown, the motor 100 also includes anti-vibration ball bearings 171. The anti-vibration ball bearings 171 are disposed between the base plate 161 and the frame 110, and the frame 110 is movably connected to the base plate 161 via the anti-vibration ball bearings 171.
[0091] The number of stabilization balls 171 can be multiple, with at least two stabilization balls 171 forming a ball group 170. For example, four stabilization balls 171 can form a ball group 170. Alternatively, three, five, or other numbers of stabilization balls 171 can form a ball group 170.
[0092] A ball groove can be formed on the base plate 161, and the ball assembly 170 is set in the ball groove. The ball groove can limit the movement of the anti-shake ball 171.
[0093] The motor 100 may include multiple ball sets 170. It is understood that the number of anti-vibration balls 171 in different ball sets 170 may be the same or different. The embodiments of this application do not further limit the number of anti-vibration balls 171 included in the motor 100 or the number of ball sets 170 composed of anti-vibration balls 171.
[0094] For example, such as Figure 9 As shown, the multiple ball sets 170 may include a first ball set 170a, a second ball set 170b, and a third ball set 170c. The first ball set 170a and the second ball set 170b may be spaced apart along a second direction Y, and the third ball set 170c may be spaced apart from the first ball set 170a and the second ball set 170b along a first direction X.
[0095] For example, the first ball bearing group 170a, the second ball bearing group 170b, and the third ball bearing group 170c can be arranged at the three vertices of the triangle. Alternatively, the first ball bearing group 170a, the second ball bearing group 170b, and the third ball bearing group 170c can also be arranged in other ways, and the embodiments of this application do not further limit this.
[0096] The image stabilization ball 171 can abut against the frame 110, allowing the frame 110 to be movably connected to the base plate 161 via the image stabilization ball 171. This allows the frame 110 to move relative to the base plate 161, thereby causing the carrier 120 and lens 210 to move relative to the base plate 161.
[0097] In some examples, such as Figure 3 , Figure 4 and Figure 9 As shown, the motor 100 also includes a second coil 144, which is disposed between the base plate 161 and the first magnet 142 and connected to the base plate 161.
[0098] The first magnet 142 is connected to the frame 110, and the second coil 144 is connected to the base plate 161. The second coil 144 is located between the base plate 161 and the first magnet 142, so that the second coil 144 can be arranged opposite to the first magnet 142 along the optical axis Z.
[0099] When the second coil 144 is energized, it generates a magnetic field. The magnetic field generated by the second coil 144 interacts with the magnetic field of the first magnet 142, thereby generating a second driving force between the second coil 144 and the first magnet 142.
[0100] The second driving force can drive the frame 110 to move relative to the base plate 161 along at least one of the first direction X and the second direction Y. The frame 110 drives the carrier 120 and the lens 210 to move relative to the base plate 161 along at least one of the first direction X and the second direction Y, so that the camera module 200 can achieve optical image stabilization.
[0101] The magnitude of the second driving force can be changed by altering the current flowing through the second coil 144. The direction of the second driving force can be changed by altering the direction of the current flowing through the second coil 144.
[0102] In the embodiments of this application, a first driving force is generated between the first coil 141 and the first magnet 142, enabling the motor 100 to drive the lens 210 to move along the optical axis direction Z to achieve autofocus. A second driving force is generated between the second coil 144 and the first magnet 142, enabling the motor 100 to drive the lens 210 to move along at least one of the first direction X and the second direction Y to achieve optical image stabilization.
[0103] The first coil 141 and the second coil 144 can also reuse the first magnet 142, which helps to simplify the structure of the motor 100, improve the production efficiency of the motor 100, and reduce the cost of the motor 100.
[0104] For example, such as Figure 4 and Figure 9As shown, the motor 100 may also include a third coil 146 and a third magnet 145. The third coil 146 is connected to the base plate 161, and the third magnet 145 is connected to the frame 110. The third coil 146 and the third magnet 145 are arranged opposite to each other along the optical axis direction Z.
[0105] When the third coil 146 is energized, it generates a magnetic field. The magnetic field generated by the third coil 146 interacts with the magnetic field of the third magnet 145, thereby generating a third driving force between the third coil 146 and the third magnet 145.
[0106] The third driving force is used to drive the frame 110 to move relative to the base plate 161 along at least one of the first direction X and the second direction Y. The frame 110 drives the carrier 120 and the lens 210 to move relative to the base plate 161 along at least one of the first direction X and the second direction Y, so that the camera module 200 can achieve optical image stabilization.
[0107] Understandably, by setting the second coil 144 and the third coil 146, the reliability of the frame 110 when moving relative to the base plate 161 can be improved, thereby improving the anti-shake reliability of the motor 100.
[0108] For example, such as Figure 9 As shown, the base 160 may also include a circuit board 163, which may include at least one of a printed circuit board (PCB) and a flexible printed circuit (FPC). The embodiments of this application do not further limit the specific form of the circuit board 163.
[0109] The circuit board 163 can be mounted on the base plate 161 and connected to the coils (e.g., the first coil 141, the second coil 144, and the third coil 146). This allows the power supply to power the coils through the circuit board 163, enabling a driving force to be generated between the coils and the magnet.
[0110] Figure 10 This is a schematic diagram of the structure of an elastic element provided in some embodiments of this application. In some examples, such as... Figure 5 and Figure 10 As shown, the motor 100 also includes an elastic element 150. For example, the elastic element 150 may include a spring sheet, or it may include other elastic structures. The embodiments of this application do not further limit the specific form of the elastic element 150.
[0111] In some examples, such as Figure 5 As shown, there can be multiple elastic elements 150, and the multiple elastic elements 150 are arranged at intervals along the circumference of the carrier 120.
[0112] For example, the number of elastic elements 150 can be four, and the four elastic elements 150 can include a first elastic element 151, a second elastic element 152, a third elastic element 153, and a fourth elastic element 154. The first elastic element 151, the second elastic element 152, the third elastic element 153, and the fourth elastic element 154 can be arranged in an array along the first direction X and the second direction Y.
[0113] Understandably, the number of elastic elements 150 can also be three, five, or more. The embodiments of this application do not further limit the number of elastic elements 150. The following example illustrates the concept of having four elastic elements 150.
[0114] like Figure 10 As shown, the elastic member 150 may include a first body portion 1501, a second body portion 1502, and a deformation portion 1504.
[0115] like Figure 5 , Figure 6 and Figure 7 As shown, the first body part 1501 is connected to the frame 110, the second body part 1502 is connected to the carrier 120, and the deformable part 1504 is connected to the first body part 1501 and the second body part 1502.
[0116] The connection methods of the first body part 1501 and the frame 110, and the connection methods of the second body part 1502 and the carrier 120 are illustrated below.
[0117] For example, such as Figure 5 As shown, a first connecting portion 101 may be provided on the end face of the frame 110 away from the base plate 161, and a second connecting portion 102 may be provided on the end face of the carrier 120 away from the base plate 161. The connecting portions (e.g., the first connecting portion 101 and the second connecting portion 102) may be connecting posts, or the connecting portions may be other connecting structures. The embodiments of this application do not further limit this.
[0118] like Figure 10 As shown, a first through hole Q1 may be formed on the first body portion 1501, and the first through hole Q1 penetrates the first body portion 1501 along the thickness direction of the first body portion 1501. Figure 6 and Figure 7 As shown, the first connecting part 101 can be embedded in the first through hole Q1, so that the first body part 1501 can be connected to the first connecting part 101.
[0119] like Figure 5As shown, the number of first connecting parts 101 can be four, including a first first connecting part 1011, a second first connecting part 1012, a third first connecting part 1013 and a fourth first connecting part 1014.
[0120] The first body portion 1501 of the first elastic member 151 can be connected to the first first connecting portion 1011, the first body portion 1501 of the second elastic member 152 can be connected to the second first connecting portion 1012, the first body portion 1501 of the third elastic member 153 can be connected to the third first connecting portion 1013, and the first body portion 1501 of the fourth elastic member 154 can be connected to the fourth first connecting portion 1014. In this way, the first elastic member 151, the second elastic member 152, the third elastic member 153, and the fourth elastic member 154 can be connected to the frame 110 respectively.
[0121] Understandably, the number of the first first connecting part 1011, the second first connecting part 1012, the third first connecting part 1013 and the fourth first connecting part 1014 may be equal or unequal, and the embodiments of this application do not further limit this.
[0122] like Figure 10 As shown, a second through hole Q2 may be provided on the second body portion 1502, and the second through hole Q2 penetrates the second body portion 1502 along the thickness direction of the second body portion 1502. Figure 6 and Figure 7 As shown, the second connecting part 102 can be embedded in the second through hole Q2, so that the second body part 1502 can be connected to the second connecting part 102.
[0123] like Figure 5 As shown, the number of second connecting parts 102 can be four, including a first second connecting part 1021, a second second connecting part 1022, a third second connecting part 1023, and a fourth second connecting part 1024.
[0124] The second body portion 1502 of the first elastic member 151 can be connected to the first second connecting portion 1021, the second body portion 1502 of the second elastic member 152 can be connected to the second second connecting portion 1022, the second body portion 1502 of the third elastic member 153 can be connected to the third second connecting portion 1023, and the second body portion 1502 of the fourth elastic member 154 can be connected to the fourth second connecting portion 1024. This allows the second elastic member 152, the third elastic member 153, and the fourth elastic member 154 to be connected to the carrier 120 respectively.
[0125] Understandably, the number of the first second connecting part 1021, the second second connecting part 1022, the third second connecting part 1023, and the fourth second connecting part 1024 may be equal or unequal, and the embodiments of this application do not further limit this.
[0126] Understandably, the first body part 1501 may be connected to the frame 110 in other ways, and the second body part 1502 may be connected to the carrier 120 in other ways. The embodiments of this application do not further limit the connection method between the first body part 1501 and the frame 110, or the connection method between the second body part 1502 and the carrier 120.
[0127] The deformable portion 1504 and the body portion (e.g., the first body portion 1504, the second body portion 1502, and the third body portion 1503) can be an integrally formed structure to improve connection reliability. For example, ... Figure 6 and Figure 7 As shown, the deformable part 1504 may include a first deformable part 1504a, which is connected to the first body part 1501 and the second body part 1502.
[0128] In some examples, the deformation section 1504 is used to generate pre-deformation so that the deformation section 1504 applies an elastic preload to the carrier 120.
[0129] Understandably, the deformation part 1504 can deform after the pre-deformation is completed, with the first body part 1501 connected to the frame 110 and the second body part 1502 connected to the carrier 120. The deformation part 1504 can undergo pre-deformation during the movement of the carrier 120 relative to the frame 110 along the optical axis Z, or when the carrier 120 is stationary relative to the frame 110 along the optical axis Z.
[0130] Understandably, pre-deformation is elastic deformation. When pre-deformation occurs in the deformation section 1504, the deformation section 1504 can apply a force to the carrier 120 under the action of elastic force, and this force is the elastic preload. Depending on the magnitude and direction of the pre-deformation, the elastic preload can have different magnitudes and directions.
[0131] In this way, the magnitude and direction of the pre-deformation of the deformation part 1504 can be adjusted to adjust the magnitude and direction of the elastic pre-tightening force, so that the carrier 120 can fit with the first guide structure 131 under the action of the elastic pre-tightening force.
[0132] For example, when the first guide structure 131 and the second guide structure 132 are respectively arranged adjacent to two corners 122 located on the diagonal of the carrier 120, for example, when one of the first guide structure 131 and the second guide structure 132 is arranged adjacent to the first corner 1221 and the other is arranged adjacent to the fourth corner 1224, the elastic preload is applied to the carrier 120 and points towards the first guide structure 131 in a clockwise or counterclockwise direction, so that the carrier 120 and the first guide structure 131 fit together.
[0133] The carrier 120 is positioned so that it points to the first guide structure 131 in a clockwise or counterclockwise direction, so that the carrier 120 can fit into the first guide structure 131 under the action of elastic preload, reducing the risk of separation between the carrier 120 and the first guide structure 131, thereby reducing the risk of the carrier 120 flipping relative to the frame 110.
[0134] Understandably, when the elastic preload acts on the carrier 120 in a clockwise or counterclockwise direction, the carrier 120 can stop the frame 110 (and / or the first guide structure 131), that is, the frame 110 (and / or the first guide structure 131) can prevent the carrier 120 from rotating around the second guide structure 132, thereby improving the reliability of the motor 100.
[0135] For example, the elastic preload can be directed clockwise or counterclockwise around the second guide structure 132 and towards the first guide structure 131, reducing the risk of the elastic preload causing the carrier 120 to separate from the second guide structure 132 and improving the reliability of the motor 100.
[0136] For example, when the first guide structure 131 and the second guide structure 132 are respectively arranged adjacent to two corners 122 located on one side of the carrier 120, such as when the first guide structure 131 and the first corner 1221 are adjacent, and the second guide structure 132 and the second corner 1222 or the third corner 1223 are adjacent, the elastic preload is applied to the carrier 120 and points towards the first guide structure 131 in the direction from the carrier 120 to the frame 110, so that the carrier 120 and the first guide structure 131 fit together.
[0137] By adopting the above-mentioned arrangement, the carrier 120 can fit in close contact with the first guide structure 131 under the action of elastic pre-tightening force, reducing the risk of separation between the carrier 120 and the first guide structure 131, thereby reducing the risk of the carrier 120 flipping relative to the frame 110.
[0138] In other examples, when the first guide structure 131 and the second guide structure 132 are respectively arranged adjacent to two corners 122 located on one side of the carrier 120, the elastic preload can also be directed around the second guide structure 132 in a clockwise or counterclockwise direction toward the first guide structure 131, so that the carrier 120 can fit into the first guide structure 131.
[0139] In the embodiments of this application, the deformation part 1504 is provided to undergo pre-deformation to apply an elastic pre-tightening force to the carrier 120. Under the action of the elastic pre-tightening force, the carrier 120 can fit with the first guide structure 131, reducing the risk of separation between the carrier 120 and the first guide structure 131. This allows the first guide structure 131 to guide and limit the movement of the carrier 120 relative to the frame 110, reducing the risk of the carrier 120 flipping relative to the frame 110 and improving the reliability of the movement of the carrier 120.
[0140] Furthermore, by using the deformation section 1504 to apply an elastic preload to the carrier 120, the carrier 120 and the first guide structure 131 are brought into contact. This eliminates the need for structures such as magnets to attract the first guide structure 131, simplifying the structure of the motor 100, improving its production efficiency, and reducing its cost. Additionally, it eliminates the need for grooves on the carrier 120 to accommodate the magnets attracting the first guide structure 131, thus improving the mechanical strength of the carrier 120.
[0141] Furthermore, the deformation part 1504 can apply elastic preload to the carrier 120 in different directions to adapt to the different positions of the first guide structure 131 and the second guide structure 132, and meet the needs under different conditions.
[0142] In some examples, the deformation portions 1504 of the multiple elastic elements 150 each have a pre-deformation amount, and the deformation portions 1504 of the multiple elastic elements 150 provide sub-elastic pre-tightening forces to the carrier 120 respectively, and the resultant force of the multiple sub-elastic pre-tightening forces is the elastic pre-tightening force.
[0143] Understandably, the directions of the multiple sub-elastic preloads can be the same or different. For example, when the elastic preload points towards the first guide structure 131 in a clockwise or counterclockwise direction, the directions of the multiple sub-elastic preloads can be different, but the resultant force of the multiple sub-elastic preloads can point towards the first guide structure 131 in a clockwise or counterclockwise direction. When the elastic preload points towards the first guide structure 131 along the direction from the carrier 120 to the frame 110, the directions of the multiple sub-elastic preloads can be the same.
[0144] Understandably, the magnitudes of the multiple sub-elastic preloads can be the same or different, and the embodiments of this application do not further limit this.
[0145] The deformation portions 1504 of multiple elastic elements 150 provide sub-elastic preload to the carrier 120. By changing the direction of different sub-elastic preloads, the direction of the resultant force of multiple sub-elastic preloads can be changed, improving the flexibility of setting the elastic preload. In addition, providing sub-elastic preload to the carrier 120 with multiple elastic elements 150 deformation portions 1504 can also increase the strength of the elastic preload.
[0146] The following example illustrates a method in which the deformation portions 1504 of multiple elastic elements 150 jointly provide elastic preload to the carrier 120.
[0147] For example, the initial setting position of the first connecting part 101 (including the first first connecting part 1011, the second first connecting part 1012, the third first connecting part 1013, and the fourth first connecting part 1014) is the position where the deformable part 1504 has not undergone pre-deformation after the first body part 1501 and the first connecting part 101 are connected. The deformation setting position of the first connecting part 101 is the position where the deformable part 1504 undergoes pre-deformation after the first body part 1501 and the first connecting part 101 are connected.
[0148] The initial setting position of the second connecting part 102 (including the first second connecting part 1021, the second second connecting part 1022, the third second connecting part 1023, and the fourth second connecting part 1024) is the position where the deformable part 1504 has not undergone pre-deformation after the second body part 1502 and the second connecting part 102 are connected. The deformation setting position of the second connecting part 102 is the position where the deformable part 1504 undergoes pre-deformation after the second body part 1502 and the second connecting part 102 are connected.
[0149] Taking the elastic preload surrounding the second guide structure 132 and pointing towards the first guide structure 131 as an example, the initial setting positions of the first second connecting part 1021, the second second connecting part 1022, the third second connecting part 1023, and the fourth second connecting part 1024 can be rotated by a set angle around the second guide structure 132 to obtain the deformation setting positions of the first second connecting part 1021, the second second connecting part 1022, the third second connecting part 1023, and the fourth second connecting part 1024.
[0150] The second body portion 1502 of the first elastic member 151, the second body portion 1502 of the second elastic member 152, the second body portion 1502 of the third elastic member 153, and the second body portion 1502 of the fourth elastic member 154 are respectively connected to the four second connecting portions 102, so that the deformation portion 1504 of the first elastic member 151, the deformation portion 1504 of the second elastic member 152, the deformation portion 1504 of the third elastic member 153, and the deformation portion 1504 of the fourth elastic member 154 can be pre-deformed respectively, thereby enabling the elastic preload to surround the second guide structure 132 and point towards the first guide structure 131.
[0151] Understandably, when the initial setting positions of the first second connecting part 1021, the second second connecting part 1022, the third second connecting part 1023, and the fourth second connecting part 1024 are rotated counterclockwise around the second guide structure 132 by a set angle to obtain the deformation setting position, the elastic preload can rotate clockwise around the second guide structure 132 and point towards the first guide structure 131.
[0152] When the initial setting positions of the first first connecting part 1011, the second first connecting part 1012, the third first connecting part 1013 and the fourth first connecting part 1014 are rotated clockwise around the second guide structure 132 by a set angle to obtain the deformation setting position, the elastic preload can rotate counterclockwise around the second guide structure 132 and point towards the first guide structure 131.
[0153] Alternatively, when the elastic preload surrounds the second guide structure 132 and points towards the first guide structure 131, the initial positions of the first first connecting part 1011, the second first connecting part 1012, the third first connecting part 1013, and the fourth first connecting part 1014 can be rotated by a set angle around the second guide structure 132 to obtain the deformed positions of the first first connecting part 1011, the second first connecting part 1012, the third first connecting part 1013, and the fourth first connecting part 1014.
[0154] The first body portion 1501 of the first elastic member 151, the first body portion 1501 of the second elastic member 152, the first body portion 1501 of the third elastic member 153, and the first body portion 1501 of the fourth elastic member 154 are respectively connected to four first connecting portions 101, so that the deformation portion 1504 of the first elastic member 151, the deformation portion 1504 of the second elastic member 152, the deformation portion 1504 of the third elastic member 153, and the deformation portion 1504 of the fourth elastic member 154 can be pre-deformed respectively, thereby enabling the elastic preload to surround the second guide structure 132 and point towards the first guide structure 131.
[0155] Understandably, when the initial setting positions of the first first connecting part 1011, the second first connecting part 1012, the third first connecting part 1013 and the fourth first connecting part 1014 are rotated counterclockwise around the second guide structure 132 by a set angle to obtain the deformation setting position, the elastic preload can rotate clockwise around the second guide structure 132 and point towards the first guide structure 131.
[0156] When the initial setting positions of the first first connecting part 1011, the second first connecting part 1012, the third first connecting part 1013 and the fourth first connecting part 1014 are rotated clockwise around the second guide structure 132 by a set angle to obtain the deformation setting position, the elastic preload can rotate counterclockwise around the second guide structure 132 and point towards the first guide structure 131.
[0157] Understandably, the set angle is greater than 0 and less than 180°, and the embodiments of this application do not further limit the value of the set angle.
[0158] Taking the elastic preload pointing towards the first guide structure 131 along the direction from the carrier 120 to the frame 110 as an example, the initial setting positions of the first second connecting part 1021, the second second connecting part 1022, the third second connecting part 1023, and the fourth second connecting part 1024 can be moved a set distance away from the first guide structure 131 along the first direction X (or the second direction Y) to obtain the deformation setting positions of the first second connecting part 1021, the second second connecting part 1022, the third second connecting part 1023, and the fourth second connecting part 1024.
[0159] The second body portion 1502 of the first elastic member 151, the second body portion 1502 of the second elastic member 152, the second body portion 1502 of the third elastic member 153, and the second body portion 1502 of the fourth elastic member 154 are respectively connected to the four second connecting portions 102, so that the deformation portion 1504 of the first elastic member 151, the deformation portion 1504 of the second elastic member 152, the deformation portion 1504 of the third elastic member 153, and the deformation portion 1504 of the fourth elastic member 154 can be pre-deformed respectively, thereby enabling the elastic pre-tightening force to point towards the first guide structure 131 along the direction from the carrier 120 to the frame 110.
[0160] Alternatively, when the elastic preload is directed toward the first guide structure 131 along the direction from the carrier 120 to the frame 110, the initial positions of the first first connecting part 1011, the second first connecting part 1012, the third first connecting part 1013, and the fourth first connecting part 1014 can be moved a predetermined distance away from the first guide structure 131 along the first direction X (or the second direction Y) to obtain the deformable positions of the first first connecting part 1011, the second first connecting part 1012, the third first connecting part 1013, and the fourth first connecting part 1014.
[0161] The first body portion 1501 of the first elastic member 151, the first body portion 1501 of the second elastic member 152, the first body portion 1501 of the third elastic member 153, and the first body portion 1501 of the fourth elastic member 154 are respectively connected to four first connecting portions 101, so that the deformation portion 1504 of the first elastic member 151, the deformation portion 1504 of the second elastic member 152, the deformation portion 1504 of the third elastic member 153, and the deformation portion 1504 of the fourth elastic member 154 can be pre-deformed respectively, thereby enabling the elastic pre-tightening force to point towards the first guide structure 131 along the direction from the carrier 120 to the frame 110.
[0162] Understandably, the embodiments of this application do not further limit the value of the set distance.
[0163] Figure 11 This is a schematic diagram showing the positional relationship between the carrier, the second magnet, and the second guide structure provided in some embodiments of this application.
[0164] In some examples, such as Figure 11 As shown, the carrier 120 has a first receiving groove M, and the first receiving groove M and the second guide structure 132 are arranged adjacent to each other. The motor 100 also includes a second magnet 143, which is located in the first receiving groove M and is used to attract the second guide structure 132.
[0165] This configuration reduces the risk of separation between the carrier 120 and the second guide structure 132, enabling the second guide structure 132 to guide and limit the movement of the carrier 120 relative to the frame 110, thereby improving the reliability of the carrier 120's movement.
[0166] In some examples, when the first coil 141 is de-energized, the elastic element 150 is used to apply a first reset force to the carrier 120, which drives the carrier 120 to reset.
[0167] Understandably, the first body part 1501 is connected to the frame 110, and the second body part 1502 is connected to the carrier 120. When the first coil 141 is energized and the first driving force drives the carrier 120 to move relative to the frame 110, the deformation part 1504 (first deformation part 1504a) can undergo elastic deformation.
[0168] When the first coil 141 is de-energized, the first driving force disappears, and the carrier 120 can be reset under the action of the first reset elastic force provided by the deformation part 1504 (first deformation part 1504a), thereby improving the motion reliability of the carrier 120. Understandably, by providing the first reset elastic force to the carrier 120 through the elastic member 150, no other elastic structure is required, which simplifies the structure of the motor 100 and reduces its cost.
[0169] For example, such as Figure 10 As shown, the elastic member 150 may also include a third body portion 1503, and the deformation portion 1504 includes a second deformation portion 1504b, which connects the first body portion 1501 and the third body portion 1503.
[0170] A third through hole Q3 may be provided on the third body part 1503, and the third through hole Q3 penetrates the third body part 1503 along the thickness direction of the third body part 1503.
[0171] like Figure 5 As shown, a third connecting part 103 may be provided on the side of the extension 162 away from the base plate 161. The third connecting part 103 may be a connecting post, or it may be other connecting structures. The embodiments of this application do not further limit this.
[0172] Understandably, the third connecting portion 103 can be embedded in the third through hole Q3, so that the third body portion 1503 can be connected to the extension portion 162. Alternatively, the third body portion 1503 and the extension portion 162 can also be connected in other ways. The embodiments of the application do not further limit the connection method between the third body portion 1503 and the extension portion 162.
[0173] The number of third connecting parts 103 can be four. The four third connecting parts 103 include a first third connecting part 1031, a second third connecting part 1032, a third third connecting part 1033 and a fourth third connecting part 1034. The four third connecting parts 103 are respectively disposed on the side of the four extensions 162 away from the base plate 161.
[0174] The third body portion 1503 of the first elastic member 151 can be connected to the first third connecting portion 1031, the third body portion 1503 of the second elastic member 152 can be connected to the second third connecting portion 1032, the third body portion 1503 of the third elastic member 153 can be connected to the third third connecting portion 1033, and the third body portion 1503 of the fourth elastic member 154 can be connected to the fourth third connecting portion 1034. This allows the first elastic member 151, the second elastic member 152, the third elastic member 153, and the fourth elastic member 154 to be connected to the extension portion 162 respectively.
[0175] Understandably, when the second coil 144 and the third coil 146 are energized, a second driving force can be generated between the second coil 144 and the first magnet 142, and a third driving force can be generated between the third coil 146 and the third magnet 145. The second driving force and the third driving force can drive the frame 110 to move along at least one of the first direction X and the second direction Y, and the deformation part 1504 (the second deformation part 1504b) can undergo elastic deformation.
[0176] When the second coil 144 and the third coil 146 are de-energized, the first and second driving forces disappear, and the frame 110 can be reset under the action of the second reset elastic force provided by the deformation part 1504 (second deformation part 1504b), thereby improving the motion reliability of the frame 110. It is understandable that by providing the second reset elastic force to the carrier 120 through the elastic member 150, no other elastic structure is required, which simplifies the structure of the motor 100 and reduces its cost.
[0177] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
