Description

Technical Field

[0001] The present invention relates to the technical field of anti-shake devices, and in particular to an anti-shake device, a camera module and an electronic device. Background Art

[0002] The anti-shake device usually includes an anti-shake component, which is connected to the photosensitive component. The anti-shake component is used to drive the photosensitive component to move within a preset plane to adjust the incident light to the photosensitive component, thereby achieving anti-shake.

[0003] However, in actual application scenarios, the internal structure of the anti-shake component may deform in a direction perpendicular to the preset plane, causing the photosensitive component to move in a direction perpendicular to the preset plane, causing the photosensitive component to deviate from the focal length of the incident light, thereby causing the photosensitive component to be unable to form a clear image. Summary of the Invention

[0004] The present invention discloses an anti-shake device, a camera module and an electronic device, which can prevent a photosensitive component from being unable to form a clear image.

[0005] In order to achieve the above objectives, the present invention discloses, on the one hand, an anti-shake device, comprising:

[0006] A housing having a mounting portion for mounting a lens, wherein the lens has an optical axis;

[0007] an anti-shake assembly, the anti-shake assembly comprising a movable member and a driving member, a portion of the driving member being connected to the housing, another portion of the driving member being connected to the movable member, and the movable member being configured to be connected to the photosensitive assembly;

[0008] a suspension assembly, the suspension assembly being connected to the movable member and the housing respectively and surrounding a circumference of the movable member or the mounting portion;

[0009] The driving member is used to drive the movable member to move, so as to drive the photosensitive component to move within a preset plane. The suspension component can be deformed in a direction parallel to the preset plane, and the suspension component supports the photosensitive component in a direction perpendicular to the preset plane.

[0010] Because the driving member is connected to the housing, the movable member is connected to the driving member, and the movable member is used to connect to the photosensitive component, when the driving member drives the movable member to move, the movable member can drive the photosensitive component to move within a preset plane. Furthermore, because the suspension assembly is respectively connected to the movable member and the housing, and the suspension assembly can deform in a direction parallel to the preset plane, when the movable member drives the photosensitive component to move within the preset plane, the suspension assembly can adaptively deform according to the movement of the movable member. In other words, the suspension assembly does not obstruct the movement of the movable member in a direction parallel to the preset plane. In this way, it is ensured that the movable member can drive the photosensitive component to move within the preset plane, thereby enabling the anti-shake device to achieve an anti-shake function.

[0011] Furthermore, because the suspension assembly supports the photosensitive component in a direction perpendicular to the predetermined plane, it can provide a retaining force on the movable member in the direction perpendicular to the predetermined plane. In other words, the suspension assembly obstructs the movement of the movable member in the direction perpendicular to the predetermined plane, thereby preventing the movable member from moving or shaking relative to the housing in the direction perpendicular to the predetermined plane. This, on the one hand, prevents the photosensitive component from deviating from the focal length of the incident light due to movement or shaking of the movable member relative to the housing in the direction perpendicular to the predetermined plane, thereby preventing the photosensitive component from being able to clearly image the image. On the other hand, it prevents the performance of the movable member moving within the predetermined plane from being affected by movement or shaking of the movable member relative to the housing in the direction perpendicular to the predetermined plane, thereby making the movement of the movable member within the predetermined plane more stable. Furthermore, because the movable member does not move or shake in the direction perpendicular to the predetermined plane, assembling the photosensitive component onto the movable member is simplified.

[0012] In addition, since the suspension assembly surrounds the movable part or the mounting portion, the suspension assembly can fully utilize the space around the movable part or the mounting portion, thereby making the anti-shake device compact and thin.

[0013] Optionally, the housing includes a first wall, a second wall, and a third wall, wherein the first wall and the third wall are arranged in a direction perpendicular to the preset plane, the second wall is arranged in a direction parallel to the preset plane, the first wall and the third wall are connected through the second wall, and the third wall encloses the mounting portion;

[0014] The suspension assembly includes at least one elastic plate, which is arranged in a direction perpendicular to the preset plane. The first end of the elastic plate is fixed to the first wall, and the second end of the elastic plate is fixed to the movable part. The first wall, the second wall and the third wall together enclose a first accommodating space. The elastic plate is accommodated in the first accommodating space and surrounds the circumference of the mounting portion.

[0015] When the suspension assembly includes an elastic plate, since the elastic plate is arranged in a direction perpendicular to the preset plane, the elastic plate will have relatively high strength in the direction perpendicular to the preset plane and relatively low strength in the direction parallel to the preset plane. This ensures that deformation does not occur in the direction perpendicular to the preset plane, while deformation can occur in the direction parallel to the preset plane. In other words, the elastic plate can function as a suspension for the movable member in the direction perpendicular to the preset plane. This ensures that the movable member can drive the photosensitive component to move within the preset plane, thereby enabling the anti-shake device to achieve its anti-shake function. At the same time, it prevents the movable member from moving or shaking relative to the housing in the direction perpendicular to the preset plane.

[0016] Wherein, when the suspension assembly includes an elastic plate, since the elastic plate is a plate-like structure and is relatively thin and light, the anti-shake device can be made more compact. In addition, since the elastic plate is easy to manufacture, the manufacturing cost of the anti-shake device can be reduced.

[0017] In addition, since the elastic plate is accommodated in the first accommodating space formed by the first wall, the second wall and the third wall and surrounds the circumference of the mounting portion, the elastic plate can fully utilize the first accommodating space without the need to open up other space in the anti-shake device for placing the elastic plate. The structural design is very clever, and therefore can save space in the anti-shake device, thereby making the anti-shake device compact and thin.

[0018] Optionally, the housing further includes: a fourth wall, the fourth wall being connected to the third wall and extending in a direction close to the optical axis, a light inlet being formed around one side of the third wall close to the optical axis, the axis of the light inlet coinciding with the optical axis, the fourth wall being arranged opposite to the movable part, and the driving part being respectively connected to the fourth wall and the movable part.

[0019] By arranging the fourth wall and the movable part relative to each other, the driving part can be arranged between the fourth wall and the movable part. This facilitates the connection of the driving part with the fourth wall and the movable part respectively, and can make the setting position of the driving part more reasonable.

[0020] In addition, by forming a light inlet around one side of the third wall close to the optical axis and making the axis of the light inlet coincide with the optical axis, when the anti-shake device is used in the camera module, the incident light can pass through the light inlet to reach the photosensitive component for imaging.

[0021] Optionally, the housing includes a fifth wall and a sixth wall, the fifth wall surrounding and connecting a side of the sixth wall away from the optical axis of the lens, the fifth wall being perpendicular to the preset plane, the sixth wall being parallel to the preset plane, a side of the sixth wall close to the optical axis surrounding a light inlet, and the mounting portion being formed on the sixth wall;

[0022] The suspension assembly includes at least one elastic plate, which is perpendicular to the preset plane. The movable part is arranged in a second accommodating space formed by the fifth wall and the sixth wall. The first end of the elastic plate is fixed on the fifth wall, and the second end of the elastic plate is fixed on the movable part. An avoidance gap is formed between the peripheral side of the movable part and the fifth wall. The elastic plate is located in the avoidance gap and surrounds the peripheral side of the movable part.

[0023] When the suspension assembly includes an elastic plate, since the elastic plate is perpendicular to the preset plane, the elastic plate will be relatively strong in the direction perpendicular to the preset plane and relatively weak in the direction parallel to the preset plane. This ensures that deformation does not occur in the direction perpendicular to the preset plane, while deformation can occur in the direction parallel to the preset plane. In other words, the elastic plate can function as a suspension for the movable member in the direction perpendicular to the preset plane. This ensures that the movable member can drive the photosensitive component to move within the preset plane, thereby enabling the anti-shake device to achieve its anti-shake function. At the same time, it prevents the movable member from moving or shaking relative to the housing in the direction perpendicular to the preset plane.

[0024] Wherein, when the suspension assembly includes an elastic plate, since the elastic plate is a plate-like structure and is relatively thin and light, the anti-shake device can be made more compact. In addition, since the elastic plate is easy to manufacture, the manufacturing cost of the anti-shake device can be reduced.

[0025] In addition, since the elastic plate is located in the avoidance gap between the peripheral side of the movable part and the fifth wall, the elastic plate can fully utilize the avoidance gap between the movable part and the fifth wall without opening up other space in the anti-shake device for placing the elastic plate. The structural design is very clever, and therefore can save space in the anti-shake device, thereby making the anti-shake device compact.

[0026] Furthermore, since the elastic plate is located on the peripheral side of the movable part, the elastic plate can minimize the space occupied by the anti-shake device in the direction perpendicular to the preset plane, thereby making the anti-shake device thinner and lighter in the direction perpendicular to the preset plane.

[0027] Optionally, in a direction perpendicular to the preset plane, the elastic plate and the movable member are spaced apart, the second end of the elastic plate has an extension portion extending in a direction close to the movable member, and the extension portion is fixedly connected to the movable member.

[0028] By spacing the elastic plate from the movable member, providing an extension at the second end of the elastic plate, and connecting the extension to the movable member, it is possible to prevent the elastic plate from contacting the movable member over a large area. This, on the one hand, prevents the elastic plate from contacting the movable member over a large area, thereby preventing the elastic plate or the movable member from being worn over a large area. On the other hand, it also reduces the strength of the elastic plate in a direction parallel to the preset plane, thereby minimizing the obstruction of the elastic plate on the movable member in a direction parallel to the preset plane, thereby ensuring smoother movement of the movable member in a direction parallel to the preset plane.

[0029] Optionally, the movable member is a movable plate, the movable plate is parallel to the preset plane, one end of the extension portion close to the movable member is bent to form a connecting plate, and the connecting plate is parallel to and connected to the movable plate.

[0030] Since the movable part is a movable plate, the movable plate is parallel to the preset plane, and the connecting plate is parallel to and connected to the movable plate, the connecting plate can be connected to the two opposite surfaces of the movable plate. It can be understood that the areas of the two opposite surfaces of the movable plate are larger than the side walls of the movable plate. Therefore, when the connecting plate can be connected to the two opposite surfaces of the movable plate, the connection between the movable part and the elastic plate can be made more secure.

[0031] Optionally, the side wall of the movable member has one or more first bending portions, and the elastic plate is bent along the bending direction of the first bending portion to form a bent plate.

[0032] When the elastic plate is bent along the bending direction of the first bending portion to form a bent plate, a second bending portion corresponding to the first bending portion can be formed on the elastic plate. It can be understood that when the elastic plate has a second bending portion, the strength of the elastic plate in the direction perpendicular to the preset plane can be further enhanced, thereby better preventing the movable part from moving or shaking in the direction perpendicular to the preset plane.

[0033] Optionally, the number of the elastic plates is two, the two elastic plates are bent to form an "L"-shaped bent plate, and the two elastic plates are arranged opposite to each other to form a frame-shaped structure.

[0034] By bending the two elastic plates to form an "L"-shaped bent plate, on the one hand, since the "L"-shaped bent plates will have a second bent portion, the strength of the elastic plate in the direction perpendicular to the preset plane can be enhanced, thereby better preventing the movable parts from moving or shaking in the direction perpendicular to the preset plane.

[0035] By making the two elastic plates form a frame structure together, the entire movable part can be enclosed by the two elastic plates, so that the elastic force of the elastic plates on the movable part can be more uniform, and the movable part can move more smoothly when moving within the preset plane.

[0036] In another aspect, the present invention discloses a camera module, comprising:

[0037] Any anti-shake device provided in the above aspect;

[0038] A photosensitive component connected to the movable part;

[0039] A focusing assembly, the focusing assembly being fixed on the mounting portion and having a mounting hole;

[0040] a lens, the lens being mounted in the mounting hole, the lens being used to receive incident light, and the optical axis of the lens being perpendicular to the preset plane;

[0041] The driving member is used to drive the movable member to move, driving the photosensitive component to move within the preset plane to irradiate the incident light to the photosensitive component, and the focusing component is used to drive the lens to move in a direction perpendicular to the preset plane to focus the incident light to the photosensitive component.

[0042] Since the suspension assembly of the anti-shake device included in the camera module can prevent the photosensitive component from being displaced in the direction perpendicular to the preset plane, on the one hand, it can avoid the situation where the photosensitive component deviates from the focal length of the incident light due to the movement or shaking of the movable part relative to the housing in the direction perpendicular to the preset plane, thereby causing the photosensitive component to be unable to form a clear image. On the other hand, it can avoid the situation where the performance of the movable part moving within the preset plane is affected due to the movement or shaking of the movable part relative to the housing in the direction perpendicular to the preset plane, thereby making the movement of the movable part within the preset plane more stable. On the other hand, since the movable part will not move or shake in the direction perpendicular to the preset plane, the work of assembling the photosensitive component on the movable part can be simplified. Based on this, when the camera module includes an anti-shake device, the shooting effect of the camera module can be improved.

[0043] On another aspect, the present invention discloses an electronic device, which includes the camera module described in the other aspect.

[0044] Since the camera module included in the electronic device has a better shooting effect, when the electronic device includes the camera module, the shooting effect of the electronic device can be improved.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] Because the driving member is connected to the housing, the movable member is connected to the driving member, and the movable member is used to connect to the photosensitive component, when the driving member drives the movable member to move, the movable member can drive the photosensitive component to move within a preset plane. Furthermore, because the suspension assembly is respectively connected to the movable member and the housing, and the suspension assembly can deform in a direction parallel to the preset plane, when the movable member drives the photosensitive component to move within the preset plane, the suspension assembly can adaptively deform according to the movement of the movable member. In other words, the suspension assembly does not obstruct the movement of the movable member in a direction parallel to the preset plane. In this way, it is ensured that the movable member can drive the photosensitive component to move within the preset plane, thereby enabling the anti-shake device to achieve an anti-shake function.

[0047] Furthermore, because the suspension assembly supports the photosensitive component in a direction perpendicular to the predetermined plane, it can provide a retaining force on the movable member in the direction perpendicular to the predetermined plane. In other words, the suspension assembly obstructs the movement of the movable member in the direction perpendicular to the predetermined plane, thereby preventing the movable member from moving or shaking relative to the housing in the direction perpendicular to the predetermined plane. This, on the one hand, prevents the photosensitive component from deviating from the focal length of the incident light due to movement or shaking of the movable member relative to the housing in the direction perpendicular to the predetermined plane, thereby preventing the photosensitive component from being able to clearly image the image. On the other hand, it prevents the performance of the movable member moving within the predetermined plane from being affected by movement or shaking of the movable member relative to the housing in the direction perpendicular to the predetermined plane, thereby making the movement of the movable member within the predetermined plane more stable. Furthermore, because the movable member does not move or shake in the direction perpendicular to the predetermined plane, assembling the photosensitive component onto the movable member is simplified.

[0048] In addition, since the suspension assembly surrounds the movable part or the mounting portion, the suspension assembly can fully utilize the space around the movable part or the mounting portion, thereby making the anti-shake device compact and thin. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0075] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0076] Figure 1 is a structural diagram of an anti-shake device provided by an embodiment of the present application and equipped with a photosensitive component. Figure 2 yes Figure 1 Exploded view of the image stabilization device with the photosensitive component installed. Figure 2A yes Figure 2A cross-sectional view of the image stabilization device with a photosensitive component installed at the AA position. Figure 3 yes Figure 1 An exploded view of the image stabilization device with a photosensitive component installed from another perspective.

[0077] See also Figure 1 、 Figure 2 、 Figure 2A and Figure 3 , the anti-shake device includes: a housing 1, an anti-shake component 2 and a suspension component 3. The housing 1 has a mounting portion 10, and the mounting portion 10 is used to mount the lens 300. The anti-shake component 2 includes a movable part 21 and a driving part 22, a part of the driving part 22 is connected to the housing 1, and the other part is connected to the movable part 21, and the movable part 21 is used to connect to the photosensitive component 4. The suspension component 3 is connected to the movable part 21 and the housing 1 respectively, and surrounds the movable part 21 or the circumference of the mounting portion 10. The driving part 22 is used to drive the movable part 21 to move, so as to drive the photosensitive component 4 to move within the preset plane S. The suspension component 3 can be deformed in a direction parallel to the preset plane S, and the suspension component 3 is perpendicular to the preset plane S ( Figure 2 Support the photosensitive component 4) in the upper and lower directions.

[0078] In the embodiment of the present application, since the driving member 22 is connected to the housing 1, the movable member 21 is connected to the driving member 22, and the movable member 21 is used to connect to the photosensitive component 4, when the driving member 22 drives the movable member 21 to move, the movable member 21 can drive the photosensitive component 4 to move within a preset plane. Among them, since the suspension component 3 is respectively connected to the movable member 21 and the housing 1, and the suspension component 3 can deform in a direction parallel to the preset plane S, when the movable member 21 drives the photosensitive component 4 to move within the preset plane, the suspension component 3 can adaptively deform according to the movement of the movable member 21. In other words, the suspension component 3 will not hinder the movement of the movable member 21 in a direction parallel to the preset plane S. In this way, it can be ensured that the movable member 21 can drive the photosensitive component 4 to move within the preset plane, thereby enabling the anti-shake device to achieve the anti-shake function.

[0079] In addition, since the suspension assembly 3 can be perpendicular to the preset plane S in the direction ( Figure 2The suspension assembly 3 supports the photosensitive component 4 in the vertical direction (in the middle and lower directions). In other words, the suspension assembly 3 can provide a retaining force on the movable member 21 in a direction perpendicular to the predetermined plane S. In other words, the suspension assembly 3 obstructs the movement of the movable member 21 in the direction perpendicular to the predetermined plane S. This prevents the movable member 21 from moving or shaking relative to the housing 1 in the direction perpendicular to the predetermined plane S. This, on the one hand, prevents the photosensitive component 4 from deviating from the focal length of the incident light due to movement or shaking of the movable member 21 relative to the housing 1 in the direction perpendicular to the predetermined plane S, thereby preventing the photosensitive component 4 from being able to clearly image. On the other hand, this prevents the movable member 21 from moving or shaking relative to the housing 1 in the direction perpendicular to the predetermined plane S, thereby preventing the movable member 21 from moving within the predetermined plane S and affecting its performance. This ensures more stable movement of the movable member 21 within the predetermined plane S. Furthermore, since the movable member 21 does not move or shake in the direction perpendicular to the predetermined plane S, assembling the photosensitive component 4 onto the movable member 21 is simplified.

[0080] In addition, since the suspension component 3 surrounds the movable part 21 or the mounting portion 10, the suspension component 3 can fully utilize the space around the movable part 21 or the mounting portion 10, thereby making the anti-shake device compact and thin.

[0081] The preset plane S refers to a plane on which the incident light can be irradiated onto the photosensitive component 4 when the photosensitive component 4 moves within the plane. In some exemplary embodiments, the preset plane S may be perpendicular to the incident direction of the incident light.

[0082] Furthermore, the photosensitive component 4 can move within the preset plane S in a variety of situations. In one possible situation, the photosensitive component 4 can move within the preset plane S along a first direction and a second direction, respectively. The first direction and the second direction can be perpendicular to each other. In this way, the anti-shake device can achieve anti-shake in the above two directions. For ease of understanding, in the field of anti-shake, the first direction and the second direction can be understood as the X direction and the Y direction, respectively. In this way, achieving anti-shake in the above two directions can be understood as achieving anti-shake in the X direction and the Y direction, respectively.

[0083] Of course, in another possible scenario, the photosensitive component 4 may also move in only one of the first direction and the second direction, which is not limited in the present embodiment. It is understandable that when the photosensitive component 4 moves in only one of the first direction and the second direction, the anti-shake device will only be able to achieve the anti-shake function in that direction.

[0084] It should be noted that, in one possible implementation, the driving member 22 included in the anti-shake assembly 2 may be a coil. When the driving member 22 is a coil, the movable member 21 may be provided with a magnet. Thus, when the coil is energized, an Ampere force may be generated between the coil and the magnet, thereby driving the movable member 21 to move within a preset plane S. When the driving member 22 is a coil and the movable member 21 is provided with a magnet, the implementation of the driving member 22 driving the movable member 21 to move within the preset plane S is very simple, and this driving method is very stable, thereby avoiding frequent abnormal situations.

[0085] In another possible implementation, see Figure 3 The driver 22 of the anti-shake assembly 2 can be an SMA (shape memory alloy) wire, which can be connected to the movable member 21. Thus, by changing the temperature of the SMA wire, the length of the SMA wire can be changed, thereby driving the movable member 21 to move within a predetermined plane S. When the driver 22 is an SMA wire, the smaller the SMA wire, the more compact the entire anti-shake device.

[0086] Of course, the driving member 22 can also achieve the purpose of driving the movable member 21 to move within the preset plane S in other possible ways, and the embodiment of the present application is not limited to this.

[0087] In some embodiments, see Figure 2 and Figure 2A The housing 1 includes a first wall 11, a second wall 12 and a third wall 13. The first wall 11 and the third wall 13 are arranged in a direction perpendicular to the preset plane S, and the second wall 12 is arranged in a direction parallel to the preset plane S. The first wall 11 and the third wall 13 are connected through the second wall 12, and the third wall 13 encloses a mounting portion 10. The suspension assembly 3 includes at least one elastic plate 31. The elastic plate 31 is arranged in a direction perpendicular to the preset plane S. The first end of the elastic plate 31 is fixed on the first wall 11, and the second end of the elastic plate 31 is fixed on the movable part 21. The first wall 11, the second wall 12 and the third wall 13 jointly enclose a first accommodating space 20. The elastic plate 31 is accommodated in the first accommodating space 20 and surrounds the circumference of the mounting portion 10.

[0088] When the suspension assembly 3 includes an elastic plate 31, since the elastic plate 31 is arranged in a direction perpendicular to the preset plane S, the elastic plate 31 will have a relatively high strength in the direction perpendicular to the preset plane S and a relatively low strength in the direction parallel to the preset plane S. This ensures that the elastic plate 31 does not deform in the direction perpendicular to the preset plane S and can deform in the direction parallel to the preset plane S. In other words, the elastic plate 31 can suspend the movable member 21 in the direction perpendicular to the preset plane S. This ensures that the movable member 21 can drive the photosensitive component 4 to move within the preset plane, thereby enabling the anti-shake device to achieve its anti-shake function. At the same time, it can prevent the movable member 21 from moving or shaking relative to the housing 1 in the direction perpendicular to the preset plane S.

[0089] Wherein, when the suspension assembly 3 includes the elastic plate 31, since the elastic plate 31 is a plate-like structure, it is relatively light and thin, and therefore, the anti-shake device can be made more compact. In addition, since the elastic plate 31 is easy to manufacture, the manufacturing cost of the anti-shake device can be reduced.

[0090] In addition, since the elastic plate 31 is accommodated in the first accommodating space 20 formed by the first wall 11, the second wall 12 and the third wall 13 and surrounds the circumference of the mounting portion 10, the elastic plate 31 can make full use of the first accommodating space 20 without the need to open up other space in the anti-shake device for placing the elastic plate 31. The structural design is very clever, and therefore can save space in the anti-shake device, thereby making the anti-shake device compact.

[0091] The number of the elastic plates 31 can be 1 or 2 ( Figure 2 The number of the elastic plates 31 may be 2), 3 or other possible numbers, which is not limited in the embodiment of the present application.

[0092] Among them, when the number of elastic plates 31 is one, in order to ensure that the elastic plate 31 can be firmly connected to the movable part 21 and to prevent the movable part 21 from tilting relative to the preset plane S, in addition to the second end of the elastic plate 31 being connected to the movable part 21, multiple connection points for connecting with the movable part 21 can also be set on the elastic plate 31. In this way, on the one hand, the connection relationship between the elastic plate 31 and the movable part 21 can be made firm, and on the other hand, the movable part 21 can be prevented from tilting relative to the preset plane S.

[0093] In other embodiments, the suspension component 3 may include a spring, one end of which is fixed to a spring fixing position of the housing 1, and the other end is fixed to a spring fixing position of the movable part 21, wherein when the spring is in a natural state, the distance between the spring fixing position of the housing 1 and the spring fixing position of the movable part 21 is the same as the length of the spring, so that the spring can prevent the movable part 21 from moving or shaking in a direction perpendicular to the preset plane S. When the movable part 21 moves within the preset plane S, the spring can deform to ensure that the movable part 21 can move within the preset plane S. It can be seen that when the suspension component 3 is a spring, it can also ensure that the movable part 21 can drive the photosensitive component 4 to move within the preset plane, while also preventing the movable part 21 from moving or shaking in a direction perpendicular to the preset plane S relative to the housing 1.

[0094] When the suspension component 3 is a spring, since the manufacturing cost of the spring is relatively low, the manufacturing cost of the anti-shake device can be reduced to a certain extent.

[0095] Of course, the suspension assembly 3 can also be other possible components, as long as it can ensure that the movable part 21 can move within the preset plane S and will not move or shake in the direction perpendicular to the preset plane S. The embodiment of the present application does not limit the suspension assembly 3.

[0096] It should be noted that, in the embodiment, the first end of the elastic plate 31 may also be fixed on the second wall 12 or the third wall 13 , etc., and this embodiment of the present application does not limit this.

[0097] Further, in some embodiments, see Figure 2 and Figure 2A The housing 1 also includes: a fourth wall 14, which is connected to the third wall 13 and extends in a direction close to the optical axis Z. A light inlet 130 is formed around one side of the third wall 13 close to the optical axis Z. The axis of the light inlet 130 coincides with the optical axis Z. The fourth wall 14 is arranged opposite to the movable part 21, and the driving part 22 is respectively connected to the fourth wall 14 and the movable part 21.

[0098] By arranging the fourth wall 14 and the movable part 21 relative to each other, the driving part 22 can be arranged between the fourth wall 14 and the movable part 21. This makes it easier for the driving part 22 to be connected to the fourth wall 14 and the movable part 21 respectively, and the setting position of the driving part 22 can be made more reasonable.

[0099] In addition, by forming a light inlet 130 around one side of the third wall 13 close to the optical axis Z, and making the axis of the light inlet 130 coincide with the optical axis Z, when the anti-shake device is used in the camera module, the incident light can pass through the light inlet 130 to reach the photosensitive component 4 for imaging.

[0100] In some embodiments, see Figure 2B and Figure 2C The housing 1 includes a fifth wall 15 and a sixth wall 16. The fifth wall 15 surrounds and connects a side of the sixth wall 16 away from the optical axis Z of the lens 300. The fifth wall 15 is perpendicular to a predetermined plane S, and the sixth wall 16 is parallel to the predetermined plane S. A light inlet 130 is formed around the side of the sixth wall 16 near the optical axis Z. A mounting portion 10 is formed on the sixth wall 16. The suspension assembly 3 includes at least one elastic plate 31. The elastic plate 31 is perpendicular to the predetermined plane S. The movable member 21 is disposed in a second accommodating space 21a formed by the fifth and sixth walls 15, 16. A first end of the elastic plate 31 is fixed to the fifth wall 15, and a second end of the elastic plate 31 is fixed to the movable member 21. An escape gap 15a is formed between the peripheral side of the movable member 21 and the fifth wall 15. The elastic plate 31 is located in the escape gap 15a and surrounds the peripheral side of the movable member 21.

[0101] When the suspension assembly 3 includes an elastic plate 31, since the elastic plate 31 is perpendicular to the preset plane S, the elastic plate 31 will have a relatively high strength in the direction perpendicular to the preset plane S and a relatively low strength in the direction parallel to the preset plane S. This ensures that the elastic plate 31 will not deform in the direction perpendicular to the preset plane S and will deform in the direction parallel to the preset plane S. In other words, the elastic plate 31 can suspend the movable member 21 in the direction perpendicular to the preset plane S. This ensures that the movable member 21 can drive the photosensitive component 4 to move within the preset plane, thereby enabling the anti-shake device to achieve its anti-shake function. At the same time, it can prevent the movable member 21 from moving or shaking relative to the housing 1 in the direction perpendicular to the preset plane S.

[0102] Wherein, when the suspension assembly 3 includes the elastic plate 31, since the elastic plate 31 is a plate-like structure, it is relatively light and thin, and therefore, the anti-shake device can be made more compact. In addition, since the elastic plate 31 is easy to manufacture, the manufacturing cost of the anti-shake device can be reduced.

[0103] In addition, since the elastic plate 31 is located in the avoidance gap 15a between the peripheral side of the movable part 21 and the fifth wall 15, the elastic plate 31 can fully utilize the avoidance gap 15a between the movable part 21 and the fifth wall 15 without opening up other space in the anti-shake device for placing the elastic plate 31. The structural design is very clever, and therefore can save space in the anti-shake device, thereby making the anti-shake device compact.

[0104] Furthermore, since the elastic plate 31 is located on the peripheral side of the movable part 21, the elastic plate 31 can minimize the space occupied in the anti-shake device in the direction perpendicular to the preset plane S, thereby making the anti-shake device thin and light in the direction perpendicular to the preset plane S.

[0105] Moreover, by making the elastic plate 31 surround the movable part 21, when there are multiple elastic plates 31, the second ends of the multiple elastic plates 31 can be evenly connected to the movable part 21. In this way, the elastic force of the elastic plate 31 on the movable part 21 can be more uniform, and the movable part 21 can be prevented from tilting relative to the preset plane S.

[0106] It should be noted that, in other embodiments, the first end of the elastic plate 31 may also be fixed on the fifth wall 15 or fixed on both the fifth wall 15 and the sixth wall 16 , which is not limited in this embodiment of the present application.

[0107] In some embodiments, see Figure 2 , in the direction perpendicular to the preset plane S, the elastic plate 31 and the movable member 21 are spaced apart (ie Figure 2 The elastic plate 31 is not aligned with the movable member 21 and there is a misalignment gap (J). The second end of the elastic plate 31 has an extension portion 311 extending toward the movable member 21 , and the extension portion 311 is fixedly connected to the movable member 21 .

[0108] By spacing the elastic plate 31 from the movable member 21 and providing an extension 311 at the second end of the elastic plate 31, and connecting the extension 311 to the movable member 21, it is possible to prevent the elastic plate 31 from making large-area contact with the movable member 21. This, on the one hand, prevents the elastic plate 31 from making large-area contact with the movable member 21, which could cause extensive wear of the elastic plate 31 or the movable member 21. On the other hand, it also reduces the strength of the elastic plate 31 in a direction parallel to the predetermined plane S, thereby minimizing the obstruction of the elastic plate 31 on the movable member 21 in the direction parallel to the predetermined plane S, thereby ensuring smoother movement of the movable member 21 in the direction parallel to the predetermined plane S.

[0109] It should be noted that, see Figure 2 In this embodiment, since the elastic plate 31 is located above the movable member 21, the extension portion 311 of the second end of the elastic plate 31 will extend downward and connect to the movable member 21. Of course, in other embodiments, see Figure 2CWhen the elastic plate 31 is located below or surrounding the movable member 21, the extension portion 311 at the second end of the elastic plate 31 can extend upward or horizontally to connect with the movable member 21 to ensure that the extension portion 311 is connected to the movable member 21. Regardless of whether the extension portion 311 at the second end of the elastic plate 31 extends downward, upward, or horizontally, it extends in a direction closer to the movable member 21. In other words, it is sufficient to provide the extension portion 311 at the second end of the elastic plate 31 and to ensure that the extension portion 311 extends in a direction closer to the movable member 21 and is connected to the movable member 21. This embodiment of the present application is not limited to this.

[0110] In some embodiments, see Figure 2 and Figure 4 The movable member 21 is a movable plate, which is parallel to the preset plane S. The end of the extension portion 311 near the movable plate is bent to form a connecting plate 312, which is parallel to and connected to the movable plate. Because the movable member 21 is a movable plate, which is parallel to the preset plane S, and the connecting plate 312 is parallel to and connected to the movable plate, the connecting plate 312 can be connected to two opposing surfaces of the movable plate. It can be understood that the area of the two opposing surfaces of the movable plate is larger than the sidewalls of the movable plate. Therefore, when the connecting plate 312 can be connected to the two opposing surfaces of the movable plate, the connection between the movable member 21 and the elastic plate 31 can be more secure.

[0111] Specifically, see Figure 2 When the end of the extension portion 311 close to the movable plate is bent to form a connecting plate 312, the connecting plate 312 can be connected to the upper surface of the movable plate. In this way, the connection relationship between the movable member 21 and the elastic plate 31 can obviously become more secure.

[0112] In some embodiments, see Figure 2 and Figure 4 The side wall of the movable member 21 has one or more first bending portions 210 , and the elastic plate 31 is bent along the bending direction of the first bending portion 210 to form a bent plate.

[0113] When the elastic plate 31 is bent along the bending direction of the first bending portion 210 to form a bent plate, a second bending portion W corresponding to the first bending portion 210 can be formed on the elastic plate 31. It can be understood that when the elastic plate 31 has a second bending portion W, the strength of the elastic plate 31 in the direction perpendicular to the preset plane S can be further enhanced, thereby better preventing the movable part 21 from moving or shaking in the direction perpendicular to the preset plane S.

[0114] Among them, according to the shape of the first bending portion 210, the shape of the bent plate formed by bending the elastic plate 31 along the bending direction of the first bending portion 210 can be various possible shapes, for example, it can be a "sawtooth" bent plate, or an "L"-shaped bent plate, or a "wavy" bent plate, etc., and the embodiments of the present application do not limit this.

[0115] When the bent plate is zigzag-shaped, the manufacturing cost of the anti-shake device can be reduced to a certain extent due to its regular shape and ease of processing. Furthermore, since the zigzag-shaped bent plate reduces the strength of the elastic plate 31 in directions parallel to the predetermined plane S and increases its strength in directions perpendicular to the predetermined plane S, the movable member 21 can move more smoothly in directions parallel to the predetermined plane S while also effectively preventing movement or shaking of the movable member 21 in directions perpendicular to the predetermined plane S.

[0116] When the bending plate is a "wavy" bending plate, in addition to having all the beneficial effects of the "sawtooth" bending plate, since the outer surface of the "wavy" bending plate is smoother, it can also make the bending plate easier to assemble and avoid scratching the hands.

[0117] In some embodiments, see Figure 2 and Figure 5 There are two elastic plates 32 , and the two elastic plates 32 are bent to form an “L”-shaped bent plate, and the two elastic plates 31 are arranged opposite to each other to form a frame structure.

[0118] By bending the two elastic plates 31 to form an "L"-shaped bent plate, on the one hand, since the "L"-shaped bent plates will have a second bent portion W, the strength of the elastic plate 31 in the direction perpendicular to the preset plane S can be enhanced, thereby better preventing the movable part 21 from moving or shaking in the direction perpendicular to the preset plane S.

[0119] By arranging the two elastic plates 31 relative to each other to form a frame structure, the entire movable part 21 can be enclosed by the two elastic plates 31, so that the elastic force of the elastic plates 31 on the movable part 21 can be more uniform, and the movable part 21 can move more smoothly when moving within the preset plane S.

[0120] In summary, in the embodiment of the present application, since the suspension assembly 3 can be arranged in a direction perpendicular to the preset plane S ( Figure 2The suspension assembly 3 supports the photosensitive component 4 in the vertical direction (in the middle and lower directions). Therefore, the suspension assembly 3 can provide a retaining force on the movable member 21 in a direction perpendicular to the predetermined plane S. In other words, the suspension assembly 3 obstructs the movement of the movable member 21 in the direction perpendicular to the predetermined plane S, thereby preventing the movable member 21 from moving or shaking relative to the housing 1 in the direction perpendicular to the predetermined plane S. This, on the one hand, prevents the photosensitive component 4 from deviating from the focal length of the incident light due to movement or shaking of the movable member 21 relative to the housing 1 in the direction perpendicular to the predetermined plane S, thereby preventing the photosensitive component 4 from being able to clearly image. On the other hand, it prevents the movable member 21 from moving or shaking relative to the housing 1 in the direction perpendicular to the predetermined plane S, thereby preventing the movable member 21 from moving within the predetermined plane S and affecting its performance. As a result, the movement of the movable member 21 within the predetermined plane S is more stable. Furthermore, since the movable member 21 does not move or shake in the direction perpendicular to the predetermined plane S, the assembly of the photosensitive component 4 onto the movable member 21 is simplified.

[0121] Figure 6 is a structural diagram of a camera module provided in an embodiment of the present application, Figure 7 yes Figure 6 The structural diagram of the camera module in another perspective. Figure 6 and Figure 7 The camera module includes: an anti-shake device 100, a photosensitive component 4, a focusing component 200, and a lens 300. The photosensitive component 4 is connected to the movable part 21, and the focusing component 200 is fixed to the mounting portion 10. The focusing component 200 has a mounting hole 201, and the lens 300 is mounted in the mounting hole 201. The lens 300 is used to receive incident light, and the optical axis of the lens is perpendicular to the preset plane S. The driving component 22 is used to drive the movable part 21 to move, driving the photosensitive component 4 to move within the preset plane S to irradiate the incident light to the photosensitive component 4. The focusing component is used to drive the lens to move in a direction perpendicular to the preset plane S to focus the incident light on the photosensitive component 4.

[0122] Among them, the structure of the anti-shake device 100 can be the same as the structure of any anti-shake device 100 in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments, and the embodiments of this application will not be repeated here.

[0123] In an embodiment of the present application, when taking a picture, first, the incident light can enter the camera module along the optical axis of the lens 300. After the incident light enters the camera module, when the incident light does not irradiate the photosensitive component 4, the driving member 22 can drive the movable member 21 to move, thereby driving the photosensitive component 4 to move within the preset plane S. Since the preset plane S is perpendicular to the optical axis, when the movable member 21 drives the photosensitive component 4 to move within the preset plane S, the incident light can be irradiated onto the photosensitive component 4. In this way, the camera module can achieve an anti-shake function. When the incident light is not focused on the photosensitive component 4, since the lens 300 is installed in the mounting hole 201 of the focusing component 200, the lens 300 can be driven by the focusing component to move in a direction perpendicular to the preset plane S to focus the incident light on the photosensitive component 4. In this way, the camera module can clearly image the photosensitive component 4, thereby enabling the camera module to capture a clear image.

[0124] Among them, since the suspension component 3 of the anti-shake device 100 included in the camera module can support the photosensitive component 4 in a direction perpendicular to the preset plane S, on the one hand, it can avoid the situation where the photosensitive component 4 deviates from the focal length of the incident light due to the movement or shaking of the movable part 21 relative to the housing 1 in a direction perpendicular to the preset plane S, thereby causing the photosensitive component to be unable to clearly image. On the other hand, it can avoid the situation where the performance of the movable part 21 moving within the preset plane S is affected by the movement or shaking of the movable part 21 relative to the housing 1 in a direction perpendicular to the preset plane S, making the movement of the movable part 21 within the preset plane S more stable. On the other hand, since the movable part 21 will not move or shake in a direction perpendicular to the preset plane S, the work of assembling the photosensitive component 4 on the movable part 21 can be simplified. Based on this, when the camera module includes the anti-shake device 100, the shooting effect of the camera module can be improved.

[0125] In some embodiments, participating Figure 8 The photosensitive component 4 may include: a photosensitive chip 41, a first circuit board 42 and a filter 43, wherein the filter 43 is fixed on the movable part 21, the first circuit board 42 is fixed on the filter 43, the photosensitive chip 41 is located between the first circuit board 42 and the filter 43, and is attached to the first circuit board 42, and the photosensitive chip 41 is electrically connected to the first circuit board 42.

[0126] By setting the filter 43, stray light in the incident light can be filtered out, so that the photosensitive chip 41 can form a clearer image, thereby achieving a better shooting effect of the camera module.

[0127] In some embodiments, see Figure 8 and Figure 9The camera module also includes a second circuit board 400, which is fixed on the housing 1. The second circuit board 400 is electrically connected to the first circuit board 42. The second circuit board 400 and the housing 1 form a cavity 500. The anti-shake component 2, the suspension component 3 and the photosensitive component 4 are all located in the cavity 500. The second circuit board 400 has an electrical connection end 401, which is exposed outside the cavity 500.

[0128] By setting up a second circuit board 400, the second circuit board 400 and the housing 1 form a cavity 500, and the anti-shake component 2, the suspension component 3 and the photosensitive component 4 are enclosed in the cavity 500, which can protect the anti-shake component 2, the suspension component 3 and the photosensitive component 4, thereby extending the life of the camera module.

[0129] In addition, by setting up a second circuit board 400, the second circuit board 400 is electrically connected to the first circuit board 42, and the electrical connection end 401 of the second circuit board 400 is exposed outside the cavity 500. In this way, the second circuit board 400 can play a role of adapter, making it convenient to electrically connect the entire camera module to external electronic components through the electrical connection end 401 of the second circuit board 400. For example, the camera module can be electrically connected to an electronic device through the electrical connection end 401 of the second circuit board 400, etc., so that the electrical connection of the camera module becomes simple.

[0131] Among them, the camera module 600 can have the same structure as the camera module 600 in the above embodiment, and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiment, and the embodiments of this application will not be repeated here.

[0132] In the embodiment of the present application, since the camera module 600 included in the electronic device has a better shooting effect, when the electronic device includes the camera module 600, the shooting effect of the electronic device can be improved.
