Description

Anti-shake motor, camera module and electronic device

[0001] The present application claims priority to the Chinese patent application No. 202411319722.3, filed on September 20, 2024, with the State Intellectual Property Office of China, and entitled "Anti-shake motor, camera module and electronic device", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of shooting devices, in particular to an anti-shake motor, a camera module and an electronic device. BACKGROUND

[0003] With the continuous development of portable electronic devices such as mobile phones, users have higher and higher requirements for the shooting performance of portable electronic devices, and electronic devices with optical anti-shake function are more and more loved by users. The traditional camera module includes an anti-shake motor and a prism, and the anti-shake motor includes a base, a first support and a second support. The first support is movably connected with the base. The second support is movably connected with the first support. The prism is fixedly connected with the second support. The prism is driven to make nodding motion by the second support, and the second support and the prism are driven to make shaking motion by the first support, so as to realize anti-shake. In the process of nodding motion, due to the large difference between the dynamic friction coefficient and the static friction coefficient between the first support and the second support, the change of the friction coefficient is nonlinear in the process of dynamic friction and static friction conversion, the control accuracy of the anti-shake motor to the second support is low, and problems such as picture shaking and trembling are prone to occur, and the optical anti-shake performance of the camera module is poor. SUMMARY

[0004] The present application provides an anti-shake motor, a camera module and an electronic device with high control accuracy and good optical anti-shake performance.

[0005] In a first aspect, the present application provides an anti-shake motor. The anti-shake motor has a light inlet hole and a light outlet hole, light propagates into the anti-shake motor from the light inlet hole along a first direction, light propagates out of the anti-shake motor from the light outlet hole along a second direction, the first direction is different from the second direction; the anti-shake motor further comprises a base, a first support, a second support, a first driving mechanism and a second driving mechanism, the first support is movably connected to the base, the second support is movably connected to the first support, the first driving mechanism is configured to drive the second support to rotate relative to the first support about a first axis, the second driving mechanism is configured to drive the first support and the second support to rotate relative to the base about a second axis, the extension direction of the first axis is different from the extension direction of the second axis, and the extension direction of the first axis is perpendicular to the plane in which the first direction and the second direction lie; the anti-shake motor further comprises a first rolling element; the first support comprises a first connecting portion, and the second support comprises a second connecting portion, the second connecting portion is arranged along the first direction relative to the first connecting portion, and the second connecting portion is movably connected to the first connecting portion through the first rolling element.

[0006] It can be understood that, in some embodiments, the first support is directly connected to the second support. At this time, the friction between the first support and the second support is the friction between the plastics, and the difference between the dynamic friction coefficient and the static friction coefficient between the first support and the second support is large. During the process in which the second support drives the prism to rotate relative to the first support about the first axis (i.e., the nodding motion of the prism), the dynamic friction and the static friction between the first support and the second support can be converted, the change in the position of the anti-shake motor and the change in the friction coefficient are nonlinear, and the control accuracy of the anti-shake motor for the nodding motion of the prism is low. When the anti-shake motor is applied to a camera module, the picture is prone to shaking, trembling and the like when the camera module is shooting pictures or videos, the optical anti-shake performance of the camera module is poor, and the imaging quality of the camera module is low.

[0007] It can be understood that, in the present embodiment, the first support and the second support are connected through the first rolling element. Therefore, the friction between the first support and the second support is the friction between the first support, the second support and the first rolling element. Compared with the scheme in which the first support is directly connected to the second support, the difference between the dynamic friction coefficient and the static friction coefficient of the first rolling element is small. During the process in which the second support drives the prism to rotate relative to the first support about the first axis (i.e., the nodding motion of the prism) and the dynamic friction and the static friction of the first rolling element are converted, the change in the position of the anti-shake motor and the change in the current are approximately linear, the change in the friction coefficient and the change in the current are also approximately linear, and the control accuracy of the anti-shake motor for the nodding motion of the prism is high. When the anti-shake motor is applied to a camera module, the picture is not prone to shaking, trembling and the like when the camera module is shooting pictures or videos, which is conducive to reducing the small-angle shaking in preview, thereby being conducive to improving the optical anti-shake performance of the camera module, improving the handheld image yield of night long exposure, and further being conducive to improving the imaging quality of the camera module.

[0008] In a possible implementation, the anti-shake motor further includes a second rolling element; the first support includes a third connecting portion, which is arranged at a position spaced apart from the first connecting portion; the second support includes a fourth connecting portion, which is arranged at a position spaced apart from the second connecting portion; the fourth connecting portion is arranged along the first direction with the third connecting portion; and the fourth connecting portion is movably connected to the third connecting portion through the second rolling element.

[0009] It can be understood that, because the first support and the second support are connected through the second rolling element, the friction between the first support and the second support is the friction between the first support, the second support and the second rolling element. Compared with the solution in which the first support and the second support are directly connected, the difference between the dynamic friction coefficient and the static friction coefficient of the second rolling element is smaller. In the process of conversion of the dynamic friction and the static friction of the second rolling element when the second support drives the prism to rotate (i.e., nodding motion) about the first axis relative to the first support, the change in the position of the anti-shake motor and the change in the current can be approximately linear, the change in the friction coefficient and the change in the current can also be approximately linear, the control accuracy of the anti-shake motor for the nodding motion of the prism is higher, when the anti-shake motor is applied to the camera module, the picture is not easy to appear shaking, trembling and the like when the camera module shoots pictures or videos, which is beneficial to reduce the small-angle shaking in preview, thereby being beneficial to improve the optical anti-shake performance of the camera module, improve the hand-held image yield of night long exposure, and further being beneficial to improve the imaging quality of the camera module.

[0010] In a possible implementation, the first rolling element is one or more rolling balls.

[0011] It can be understood that, because the first rolling element is one or more rolling balls, the movement friction between the first connecting portion and the second connecting portion is reduced, thereby being beneficial to reduce the movement friction between the first support and the second support.

[0012] In a possible implementation, the second rolling element is one or more rolling balls.

[0013] It can be understood that, because the second rolling element is one or more rolling balls, the movement friction between the third connecting portion and the fourth connecting portion is reduced, thereby being beneficial to reduce the movement friction between the first support and the second support.

[0014] In a possible implementation, the material of the first rolling element is ceramic or metal.

[0015] It can be understood that, because the material of the first rolling element is ceramic or metal, the difference between the dynamic friction coefficient and the static friction coefficient of the first rolling element is smaller, and the difference between the dynamic friction and the static friction received by the first rolling element is smaller.

[0016] In a possible implementation, the material of the second rolling member is ceramic or metal.

[0017] It can be understood that, since the material of the second rolling member is ceramic or metal, the difference between the dynamic friction coefficient and the static friction coefficient of the second rolling member is small, and the difference between the dynamic friction force and the static friction force acting on the second rolling member is small.

[0020] In a possible implementation, the first connecting portion includes a first metal portion, and the first rolling member rolls on the first metal portion.

[0021] It can be understood that, since the material of the first metal portion is metal, the friction between the first metal portion and the first rolling member is small, and the first metal portion can provide reliable support for the first rolling member, avoiding the first rolling member from causing pits and the like in the first connecting portion of the first support.

[0022] In a possible implementation, the first metal portion is provided with a first accommodating space, and the first rolling member is arranged in the first accommodating space.

[0023] It can be understood that, the first accommodating space can limit the first rolling member, and the first rolling member is not easy to be pulled out from the first accommodating space.

[0031] It can be understood that, in the process of rotating the second support around the first axis relative to the first support, the magnetic force between the third magnetic body and the first magnetic attraction piece and the magnetic force between the fourth magnetic body and the first magnetic attraction piece can prevent the second support from tilting or falling out relative to the first support, thereby improving the stability of the motion of the anti-shake motor.

[0032] It can be understood that, compared with the magnetic attraction scheme in which the first magnetic body is arranged opposite to the first magnetic attraction piece and the magnetic attraction scheme in which the second magnetic body is arranged opposite to the first magnetic attraction piece, the magnetic force of the magnetic attraction scheme in the embodiment is stronger, the second support is less likely to tilt or fall out relative to the first support, and the stability of the motion of the anti-shake motor is higher.

The directions of the first driving force and the second driving force are opposite, thereby driving the first support and the second support to rotate relative to the base around the second axis together, in other words, driving the first support and the second support to swing relative to the base together. At this time, the prism can rotate relative to the base around the second axis under the action of the first support and the second support, thereby realizing optical anti-shake.

It can be understood that the material of the second metal portion 1452 is metal, the friction between the second metal portion 1452 and the first rolling member 161 is small, and the second metal portion 1452 can provide reliable support for the second rolling member 162, avoiding the second rolling member 162 from causing concave pits and the like on the third connecting portion 145 of the first support 14. In addition, the second accommodating space 14521 can limit the second rolling member 162, and the second rolling member 162 is not easy to come out of the second accommodating space 14521.

[0174] Exemplarily, the first metal portion 1442 and the second metal portion 1452 can make the line connecting the ball center of the first rolling member 161 and the ball center of the second rolling member 162 perpendicular to the first direction Z.

[0176] Exemplarily, the material of the second rolling member 162 can be ceramic or metal, and the metal can be SUS316L, SUS430 or the like. It can be understood that since the material of the second rolling member 162 is ceramic or metal, the difference between the dynamic friction coefficient and the static friction coefficient of the second rolling member 162 is small, and the difference between the dynamic friction force and the static friction force received by the second rolling member 162 is small.

[0186] For example, at least part of the fourth rolling member 164 can be located in the third guide slot 1142, and at least part of the fourth rolling member 164 can be located in the fourth guide slot 1432. It can be understood that the third guide slot 1142 and the fourth guide slot 1432 can limit the fourth rolling member 164, preventing the fourth rolling member 164 from being separated from the first support 14 and the base 11.

[0195] It can be understood that, during the movement of the first support 14 relative to the base 11, the magnetic force between the seventh magnetic body 187 and the second magnetic attraction member 192 keeps the base 11, the first support 14 and the third rolling member 163 in contact, and keeps the base 11, the first support 14 and the fourth rolling member 164 in contact, which can prevent the first support 14 from tilting or falling out relative to the base 11, thereby improving the stability of the movement of the anti-shake motor 1.

For example, the first side portion 152 and the second side portion 153 of the second support 15 can be independent structural members, and fixedly connected with the support portion 151 by means of gluing, welding or the like.

In this embodiment, the fourth connecting part 155 and the second connecting part 154 are symmetrical structures. The basic design of the component structure of the fourth connecting part 155, the design of the connection relationship between components, and the design of the connection relationship between the component and other structures besides the assembly can all refer to the relevant scheme of the second connecting part 154.

[0217] As shown in FIG. 30 and FIG. 31, exemplarily, the anti-shake motor 1 can further include a first magnetic body 181, a second magnetic body 182, and a first magnetic attraction part 191. The first magnetic body 181 and the second magnetic body 182 can each be a magnet or other component with magnetism.

[0219] Exemplarily, the first magnetic body 181 can be substantially parallel to the plate surface of the at least part of the first magnetic member 191. In an embodiment, the polarity direction of the first magnetic body 181 can be substantially perpendicular to the plate surface of the at least part of the first magnetic member 191, in other words, the included angle between the polarity direction of the first magnetic body 181 and the plate surface of the at least part of the first magnetic member 191 can be substantially 90 degrees.

[0220] In other embodiments, the angle of the included angle between the polarity direction of the first magnetic body 181 and the plate surface of the at least part of the first magnetic member 191 can also be other values, for example, 85 degrees, 95 degrees, etc. The specific application is not limited.

[0221] Exemplarily, the second magnetic body 182 can be fixedly connected with the first bracket 14. In an embodiment, the second magnetic body 182 can be embedded in the third connecting portion 145.

[0222] Exemplarily, the second magnetic body 182 can be substantially parallel to the plate surface of the at least part of the first magnetic member 191. In an embodiment, the polarity direction of the second magnetic body 182 can be substantially perpendicular to the plate surface of the at least part of the first magnetic member 191, in other words, the included angle between the polarity direction of the second magnetic body 182 and the plate surface of the at least part of the first magnetic member 191 can be substantially 90 degrees.

[0223] In other embodiments, the angle of the included angle between the polarity direction of the second magnetic body 182 and the plate surface of the at least part of the first magnetic member 191 can also be other values, for example, 85 degrees, 95 degrees, etc. The specific application is not limited.

In an embodiment, a part of the first magnetic member 191 can be embedded in the second connecting portion 154, and a part can be embedded in the fourth connecting portion 155 (see FIG. 24).

[0224] Exemplarily, the first magnetic body 181 and the at least part of the first magnetic member 191 can be oppositely arranged. The first rolling member 161 can be located between the first magnetic body 181 and the first magnetic member 191, and the magnetic force between the first magnetic body 181 and the first magnetic member 191 can keep the first bracket 14, the second bracket 15 and the first rolling member 161 in contact. It can be understood that in the process of rotating the second bracket 15 relative to the first bracket 14 around the first axis R1, the magnetic force between the first magnetic body 181 and the first magnetic member 191 can keep the first bracket 14, the second bracket 15 and the first rolling member 161 in contact, which can prevent the second bracket 15 from tilting or falling out relative to the first bracket 14, thereby improving the stability of the movement of the anti-shake motor 1.

[0225] Exemplarily, the second magnetic body 182 can be disposed opposite to at least part of the first magnetic attraction member 191.

The magnetic force between the second magnetic body 182 and the first magnetic attraction member 191 can keep the first support 14, the second support 15 and the second rolling member 162 in contact. It can be understood that, during the rotation of the second support 15 relative to the first support 14 about the first axis R1, the magnetic force between the second magnetic body 182 and the first magnetic attraction member 191 can keep the first support 14, the second support 15 and the second rolling member 162 in contact, which can prevent the second support 15 from tilting or falling out relative to the first support 14, thereby improving the stability of the motion of the anti-shake motor 1.

[0226] FIG. 32 is a schematic diagram of a partial structure of the camera module 100 shown in FIG. 4 in an embodiment. FIG. 33 is a schematic diagram of a partial cross-section of the camera module 100 shown in FIG. 32 in an embodiment.

[0227] As shown in FIGS. 32 and 33, the prism 2 can be fixedly connected with the second support 15. Exemplarily, the prism 2 can be located in the mounting space 156 of the second support 15 and fixedly connected with the mounting inclined surface 1511 of the support portion 151 of the second support 15.

[0228] Exemplarily, the prism 2 can be fixedly connected with the support portion 151 by means of gluing or the like. It can be understood that the prism 2 and the mounting inclined surface 1511 can be in close contact or there can be a slight gap. The slight gap can be formed by an air gap or the thickness of a fixing member (e.g., a glue layer or the like). At this time, the slight gap between the prism 2 and the mounting inclined surface 1511 can be ignored.

[0229] As shown in FIG. 33, the first driving mechanism 131 can be used to drive the second support 15 to rotate relative to the first support 14 about the first axis R1. In other words, the first driving mechanism 131 can be used to drive the second support 15 and the prism 2 to perform nodding motion relative to the first support 14.

[0230] Exemplarily, when the first coil 1311 is applied with a signal, the first coil 1311 and the first magnetic member 1312 can cooperate to generate a driving force perpendicular to the first axis R1, thereby being used to drive the second support 15 to rotate relative to the first support 14 about the first axis R1. At this time, the prism 2 can be driven by the second support 15 to rotate relative to the base 11 about the second axis R2, thereby realizing optical anti-shake of the camera module 100. In addition, since the second connecting portion 154 and the first connecting portion 144 are arranged along the first direction Z and the fourth connecting portion 155 and the third connecting portion 145 are arranged along the first direction Z, the second support 15 is not prone to perform motion other than rotation about the second axis R2 relative to the first support 14.

[0231] Exemplarily, the first sensor can be used to detect the magnetic field change of the first magnetic piece 1312 when the second support 15 rotates around the first axis R1 by different angles, so as to detect the angle of rotation of the second support 15 around the first axis R1, and thus detect the accurate position of the anti-shake motor 1. In this way, when the camera module 100 shakes, the anti-shake motor 1 can accurately adjust the angle of rotation of the second support 15 around the first axis R1 according to the position of the anti-shake motor 1 detected by the first sensor, so as to improve the control accuracy of the anti-shake motor 1 and improve the anti-shake accuracy.

[0232] FIG. 34 is a simulation diagram of the camera module 100 shown in FIG. 33 when the second support 15 rotates around the first axis R1 relative to the first support 14.

[0233] In the diagram, the abscissa represents the current through the first coil 1311, and the ordinate represents the position change of the anti-shake motor 1 detected by the first sensor. The solid line represents the actually measured curve, and the dashed line represents the curve fitted according to the actually measured curve.

[0234] As shown in FIG. 34, during the process that the current through the first coil 1311 gradually increases or gradually decreases, the position change of the anti-shake motor 1 and the change of the current are linear.

[0235] In some embodiments, the first support 14 is directly connected with the second support 15. At this time, the friction between the first support 14 and the second support 15 is the friction between plastics, and the difference between the dynamic friction coefficient and the static friction coefficient between the first support 14 and the second support 15 is large. During the process that the second support 15 drives the prism 2 to rotate around the first axis R1 relative to the first support 14, the dynamic friction and the static friction of the first support 14 and the second support 15 can be converted, the change of the position of the anti-shake motor 1 and the friction coefficient is nonlinear, the control accuracy of the anti-shake motor 1 on the nodding movement of the prism 2 is low, and the camera module 100 is prone to shaking, trembling and other situations when shooting pictures or videos, the optical anti-shake performance of the camera module 100 is poor, and the imaging quality of the camera module 100 is low.

[0236] It can be understood that, in the embodiment, since the first support 14 and the second support 15 are connected through the first rolling member 161 and the second rolling member 162, the friction between the first support 14 and the second support 15 is the friction between the first support 14, the second support 15 and the rolling ball. Compared with the scheme that the first support 14 and the second support 15 are directly connected, the difference between the dynamic friction coefficient and the static friction coefficient of the first rolling member 161 and the second rolling member 162 is smaller. In the process of the dynamic friction and the static friction conversion of the first rolling member 161 and the second rolling member 162 when the second support 15 drives the prism 2 to rotate (that is, nodding motion) around the first axis R1 relative to the first support 14, the change of the position of the anti-shake motor 1 and the change of the current are approximately linear, the change of the friction coefficient and the change of the current are also approximately linear, the control accuracy of the anti-shake motor 1 on the nodding motion of the prism 2 is higher, the picture is not easy to appear shaking, trembling and other situations when the camera module 100 shoots pictures or videos, which is beneficial to reduce the small angle of preview shaking, thereby being beneficial to improve the optical anti-shake performance of the camera module 100, improve the hand-held exposure rate of night scene, and further improve the imaging quality of the camera module 100.

[0237] The above describes the related structure of the camera module 100 in some embodiments in combination with related drawings. The technical problems that can be solved by the camera module 100 in some embodiments will be specifically described in combination with related drawings.

[0238] Please refer to FIG. 33. It can be understood that the prism 2 can be fixedly connected with the second support 15. The second support 15 can be movably connected with the first support 14, and the first rolling member 161 and the second rolling member 162 can be connected between the first support 14 and the second support 15.

[0252] It can be understood that, in the process of rotating the second support 15 relative to the first support 14 around the first axis R1, the magnetic force between the third magnetic body 183 and the first magnetic attraction member 191 and the magnetic force between the fourth magnetic body 184 and the first magnetic attraction member 191 can prevent the second support 15 from tilting or falling out relative to the first support 14, thereby improving the stability of the movement of the anti-shake motor 1.

[0256] Exemplarily, the fifth magnetic body 185 can be arranged to be approximately at an angle with at least part of the plate surface of the first magnetic attraction member 191. In an embodiment, the angle between the polarity direction of the fifth magnetic body 185 and at least part of the plate surface of the first magnetic attraction member 191 can be approximately 45 degrees.

In an embodiment, the angle between the polarity direction of the sixth magnetic body 186 and at least part of the plate surface of the first magnetic attraction member 191 can be approximately 45 degrees.

[0259] In other embodiments, the angle between the polarity direction of the sixth magnetic body 186 and at least part of the plate surface of the first magnetic attraction member 191 can also be other values, for example, 30 degrees, 60 degrees, etc. The specific application is not limited.

[0260] Exemplarily, the magnetic force between the fifth magnetic body 185 and the first magnetic attraction member 191 and the magnetic force between the sixth magnetic body 186 and the first magnetic attraction member 191 can make the first support 14, the second support 15 and the second rolling member 162 (see FIG. 33) remain in contact.

[0261] It can be understood that, in the process of rotating the second support 15 relative to the first support 14 around the first axis R1, the magnetic force between the fifth magnetic body 185 and the first magnetic attraction member 191 and the magnetic force between the sixth magnetic body 186 and the first magnetic attraction member 191 can cause the first support 14, the second support 15 and the first rolling member 161 to remain in contact, thereby preventing the second support 15 from tilting or falling out relative to the first support 14, and thus improving the stability of the movement of the anti-shake motor 1.

[0262] It can be understood that, compared with the magnetic attraction scheme in which the first magnetic body 181 and the first magnetic attraction member 191 are arranged opposite to each other, and the magnetic attraction scheme in which the second magnetic body 182 and the first magnetic attraction member 191 are arranged opposite to each other, the magnetic attraction scheme in the present embodiment has stronger magnetic force, the second support 15 is less likely to tilt or fall out relative to the first support 14, and the stability of the movement of the anti-shake motor 1 is higher.

[0263] The above describes the magnetic attraction scheme of the camera module 100 in some embodiments in combination with related drawings. The relevant structures of the camera module 100 in some embodiments will be described in detail below in combination with related drawings. It can be understood that the relevant designs of the camera module 100 shown in the foregoing can also be directly applied to the structural design of the camera module 100 shown below without conflict. Among them, most of the technical contents of the camera module 100 shown in the foregoing will not be repeated below.

[0264] FIG. 37 is a partial cross-sectional schematic view of an embodiment of the camera module 100 shown in FIG. 32 at the line J-J.

[0265] Referring to FIG. 37, and in combination with FIG. 33, the second driving mechanism 132 can be used to drive the first support 14, the second support 15 and the prism 2 to rotate relative to the base 11 around the second axis R2, in other words, the second driving mechanism 132 can be used to drive the first support 14, the second support 15 and the prism 2 to make a pan movement relative to the base 11.

[0266] Exemplarily, when the second coil 1321 is applied with a signal, the second coil 1321 and the second magnetic member 1323 can cooperate to generate a first driving force perpendicular to the plane in which the first direction Z and the second direction X lie. When the third coil 1322 is applied with a signal, the third coil 1322 and the third magnetic member 1324 can cooperate to generate a second driving force perpendicular to the plane in which the first direction Z and the second direction X lie. Wherein, the directions of the first driving force and the second driving force are opposite, so as to drive the first support 14 and the second support 15 to rotate together around the second axis R2 relative to the base 11, in other words, to drive the first support 14 and the second support 15 to make a pan movement relative to the base 11. At this time, the prism 2 can rotate around the second axis R2 relative to the base 11 under the action of the first support 14 and the second support 15, so as to realize optical image stabilization of the camera module 100. In addition, by arranging the second coil 1321 and the second magnetic member 1323, the third coil 1322 and the third magnetic member 1324, the efficiency of the movement of the first support 14 and the second support 15 relative to the base 11 can be improved, so as to improve the stabilization efficiency of the anti-shake motor 1.

[0267] Exemplarily, in the process of the first support 14 and the second support 15 making a pan movement relative to the base 11, the magnetic force between the seventh magnetic body 187 and the second magnetic attraction member 192 makes the base 11, the first support 14 and the third rolling member 163 keep in contact, and also makes the base 11, the first support 14 and the fourth rolling member 164 keep in contact, which can prevent the first support 14 from tilting or falling out relative to the base 11, so as to improve the stability of the movement of the anti-shake motor 1.

[0268] Exemplarily, the second sensor can be used to detect the magnetic field change of the third magnetic member 1324 when the first support 14 and the second support 15 rotate around the second axis R2 by different angles, so as to detect the angle of the first support 14 and the second support 15 rotating around the second axis R2, and thus detect the accurate position of the anti-shake motor 1. In this way, when the camera module 100 shakes, the anti-shake motor 1 can accurately adjust the angle of the first support 14 and the second support 15 rotating around the second axis R2 according to the position of the anti-shake motor 1 detected by the second sensor, so as to improve the control accuracy of the anti-shake motor 1 and improve the anti-shake accuracy.

[0271] Exemplarily, the shell 17 can include a top wall 171, a first side wall 172, a second side wall 173, a third side wall 174, and a fourth side wall 175. The first side wall 172, the second side wall 173, the third side wall 174, and the fourth side wall 175 can be located at the same side of the top wall 171 and fixedly connected with the top wall 171. In other embodiments, the shell 17 can also have other structures.

[0272] Exemplarily, the light inlet hole 1a can be located at the top wall 171. The light outlet hole 1b can be located at the first side wall 172. The light inlet hole 1a and the light outlet hole 1b can communicate with each other. The light can propagate into the anti-shake motor 1 from the light inlet hole 1a along the first direction Z, and propagate out of the anti-shake motor 1 from the second direction X after being reflected by the prism 2.

[0273] Exemplarily, the shell 17 can be covered on the base 11, and the first side wall 172, the second side wall 173, the third side wall 174, and the fourth side wall 175 of the shell 17 can be fixedly connected with the base 11. The third side wall 174 can be oppositely arranged with the third side plate 114 of the base 11.

[0274] Exemplarily, the shell 17 can be fixedly connected with the base 11 by means of gluing, welding, or the like. The shell 17 can be assembled and cooperated with the base 11 to jointly encapsulate and protect the internal structure of the anti-shake motor 1.
