Description

Technical Field

[0001] This application belongs to the field of camera equipment technology, and in particular relates to a stabilization module and electronic equipment. Background Technology

[0002] Currently, OIS (Optical Image Stabilizer) is widely used in electronic devices. OIS refers to the use of optical components in electronic devices to avoid or reduce camera shake during the capture of optical signals, thereby improving image quality. Specifically, lenses equipped with OIS systems are movable. When the electronic device shakes, the OIS system uses specific algorithms to drive the shaking lens back to its initial position, thus achieving image stabilization.

[0003] In related technologies, OIS-type VCMs (Voice Coil Motors) employ a structure of spring plates and suspension wires to achieve jitter reset of the OIS section. For example, one end of the suspension wire is connected to the spring plate, and the other end is connected to the base of the VCM. This connection structure provides elastic restoring force to the OIS section connected to the spring plate.

[0004] In the aforementioned connection structure, to ensure the elastic restoring force for the OIS section, the length of the suspension wire needs to be maintained, which contradicts the requirement to reduce the size of the module and electronic device. Therefore, there is an urgent need for a stabilization module that can both maintain the length of the suspension wire and reduce the module size, thereby meeting the requirement to reduce the size of electronic devices. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a stabilization module and electronic device that can both ensure the length of the suspension wire and reduce the size of the module, thereby meeting the requirement of reducing the size of electronic devices.

[0006] In a first aspect, this application provides an image stabilization module, comprising:

[0007] A housing; a fixed component, a movable component, and a circuit board disposed within the housing, wherein the fixed component is connected to the housing and can drive the movable component to move within the housing;

[0008] The movable component is disposed on the first side of the fixed component, and the circuit board is disposed on the second side of the fixed component. The first side and the second side are opposite sides, and the second side is closer to the opening side of the housing.

[0009] The fixing component has at least one support protrusion on the second side, the plane of the circuit board that contacts the second side has a first linear distance to the first side, the side of the support protrusion away from the fixing component has a second linear distance to the first side, and the second linear distance is greater than the first linear distance;

[0010] The anti-shake module also includes at least one suspension wire, one end of which is connected to the moving component and the other end of which is connected to the support protrusion. When the fixed component drives the moving component to move, the suspension wire is used to support the moving component to perform anti-shake movement relative to the fixed component.

[0011] In some embodiments, the support protrusion has a third linear distance from the side away from the fixing component to the second side in the height direction of the stabilization module, and the circuit board has a fourth linear distance from the side away from the fixing component to the second side in the height direction of the stabilization module, wherein the third linear distance is greater than or equal to the fourth linear distance.

[0012] In some embodiments, the movable component includes a movable bracket, a first spring, a second spring, and a lens bracket. The movable bracket surrounds the lens bracket and there is a gap between the movable bracket and the lens bracket. The first spring is disposed on a third side of the lens bracket, and the second spring is disposed on a fourth side of the lens bracket. The third side and the fourth side are opposite sides, and the fourth side is close to the fixed component. Both the first spring and the second spring are fixedly connected to the lens bracket, and both the first spring and the second spring are fixedly connected to the movable bracket.

[0013] In some embodiments, one end of the suspension wire is connected to and connected to the first spring sheet, and the other end of the suspension wire is connected to the support protrusion, wherein at least one of the suspension wires is electrically connected to the first spring sheet;

[0014] The fixing component includes a fixing bracket and a metal circuit. The metal circuit is disposed on the fixing bracket, which has a through hole. A first receiving cavity is disposed inside the supporting protrusion. The through hole communicates with the first receiving cavity. One end of the suspension wire passes through the through hole and extends into the first receiving cavity, and is connected to the metal circuit inside the first receiving cavity. The suspension wire, which is electrically connected to the first spring, is electrically connected to the metal circuit, and the metal circuit is electrically connected to the circuit board.

[0015] In some embodiments, the movable component further includes a magnetic element disposed on the movable bracket, and the fixed component further includes a first coil disposed on the fixed bracket and electrically connected to the metal circuit. When the first coil is energized, it can drive the movable component to move in the housing along a first direction or a second direction by exerting a force on the magnetic element.

[0016] In some embodiments, the moving component further includes a second coil disposed on the lens bracket and electrically connected to the first spring. When the second coil is energized, it can drive the lens bracket to move in a third direction within the moving bracket by exerting a force on the magnetic element.

[0017] In some embodiments, the first coil is a flexible circuit board coil; the metal circuit is provided with OISIC and / or HallIC.

[0018] In some embodiments, the fixing component has a support protrusion at each of the four corners on the second side, and the anti-shake module includes four suspension wires, which are respectively connected to the support protrusions at the corresponding positions.

[0019] In some embodiments, the circuit board is provided with a clearance structure through which the support protrusion can pass, and the shape of the clearance structure matches the shape of the support protrusion.

[0020] In a second aspect, this application provides an electronic device comprising: a lens assembly and an image stabilization module as described in the first aspect, wherein the lens assembly is disposed on the movable component.

[0021] The image stabilization module provided in this application includes a housing, a fixed component, a movable component, and a circuit board disposed within the housing. The fixed component is connected to the housing and can drive the movable component to move within the housing. The movable component is disposed on a first side of the fixed component, and the circuit board is disposed on a second side of the fixed component. The first side and the second side are opposite sides, with the second side closer to the opening side of the housing. The fixed component has at least one support protrusion on the second side, with a first linear distance between the side of the support protrusion away from the fixed component and the second side. The circuit board has a second linear distance between the side of the circuit board away from the fixed component and the second side. The first linear distance is greater than or equal to the second linear distance. One end of a suspension wire is connected to the movable component, and the other end is connected to the support protrusion. When the fixed component drives the movable component to move, the suspension wire supports the movable component in its image stabilization movement relative to the fixed component.

[0022] Because one end of the suspension wire is connected to the support protrusion, and the first linear distance is greater than the second linear distance, the bottom of the fixing component and the support protrusion form a groove. The circuit board is set in the groove formed by the support protrusion. This structure can ensure the length of the suspension wire while reducing the height of the stacked fixing component and circuit board, thereby reducing the height of the entire image stabilization module and shrinking its size, thus meeting the requirement of shrinking the size of electronic devices.

[0023] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0036] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0037] Unless otherwise specified, the width direction of the stabilization module in this application is the horizontal direction of the stabilization module, i.e., the X direction; the length direction of the stabilization module is the vertical direction of the stabilization module, i.e., the Y direction; and the height direction of the stabilization module is the vertical direction of the stabilization module, i.e., the Z direction.

[0038] Figure 1 This is a schematic cross-sectional view of the image stabilization module provided by related technologies. For example... Figure 1 As shown, in related technologies, OIS-type VCMs (Voice Coil Motors) employ a structure of a spring plate and a suspension wire a to achieve the jitter reset of the OIS section. For example, one end of the suspension wire a is connected to the spring plate, and the other end of the suspension wire a is connected to the base b of the VCM. This connection structure provides an elastic restoring force to the OIS section connected to the spring plate.

[0039] In the aforementioned connection structure, to ensure the elastic restoring force for the OIS section, the length of the suspension wire 'a' needs to be maintained, which contradicts the requirement to reduce the size of the module and electronic device. Therefore, there is an urgent need for a stabilization module that can both maintain the length of the suspension wire 'a' and reduce the module size, thereby meeting the requirement to reduce the size of electronic devices.

[0040] In view of the above problems, this application provides a stabilization module and electronic device that can both ensure the length of the suspension wire and reduce the size of the module, thereby meeting the requirement of reducing the size of electronic devices.

[0041] Figure 2 This is a schematic cross-sectional view of a stabilization module provided in an embodiment of this application. Figure 3 This is a schematic exploded view of a stabilization module provided in an embodiment of this application. Figure 4 This is a schematic exploded view of another image stabilization module provided in the embodiments of this application. In a first aspect, embodiments of this application provide an image stabilization module, such as... Figures 2 to 4 As shown, the image stabilization module of this application includes a housing 10, a moving component 20, a fixing component 30, and a circuit board 40. The moving component 20, the fixing component 30, and the circuit board 40 are all disposed within the housing 10. A base plate is also provided at the bottom of the housing 10 for sealing the components inside the housing 10. Figure 2 and Figure 3 The base plate is not shown.

[0042] The fixing component 30 is connected to the housing 10. The fixing component 30 can be connected to the housing 10 by adhesive or by welding. The fixing component 30 can drive the moving component 20 to move within the housing 10.

[0043] See also Figures 2 to 4 The movable component 20 is disposed on the first side 31 of the fixed component 30, and the circuit board 40 is disposed on the second side 32 of the fixed component 30. The first side 31 and the second side 32 are opposite sides, and the second side 32 is closer to the opening side of the housing 10. That is, the movable component 20, the fixed component 30 and the circuit board 40 are stacked sequentially in the Z direction, away from the top of the housing 10.

[0044] See also Figures 2 to 4 The second side 32 of the fixing component 30 is provided with at least one support protrusion 301. The support protrusion 301 can be an integral part of the fixing component 30 or a separate structure. The plane of the circuit board 40 in contact with the second side 32 has a first linear distance to the first side 31, and the side of the support protrusion 301 away from the fixing component 30 has a second linear distance to the first side 31, the second linear distance being greater than the first linear distance. This forms a groove between the support protrusion 301 and the fixing component 30, within which the circuit board 40 can be disposed. Figure 1 Compared to the related image stabilization modules shown, the related image stabilization modules do not have a support protrusion, so the bottom of the fixing component is flush with the surface, and the circuit board 40 is also flush with the bottom of the fixing component. Therefore, the image stabilization module of this application, based on the support protrusion at the bottom of the fixing component, can significantly reduce the overall height of the image stabilization module.

[0045] In addition, the support protrusion 301 has a third linear distance D1 between the side away from the fixing component 30 and the second side 32 in the height direction of the anti-shake module, and the circuit board 40 has a fourth linear distance D2 between the side away from the fixing component 30 and the second side 32 in the height direction of the anti-shake module.

[0046] With at least one support protrusion 301 provided at the bottom of the fixing component 30, a groove for placing the circuit board 40 is formed at the bottom of the fixing component 30. The third linear distance D1 can be equal to the fourth linear distance D2, so that the side of the circuit board 40 away from the fixing component 30 is flush with the side of the support protrusion 301 away from the fixing component 30.

[0047] The third straight-line distance D1 can be greater than the fourth straight-line distance D2, so that the circuit board 40 is completely embedded in the groove, and the side of the circuit board 40 away from the fixing component 30 will not rub against other components, thereby reducing the risk of damage to the circuit board 40.

[0048] like Figures 2 to 4 As shown, the image stabilization module also includes at least one suspension wire 50. One end of the suspension wire 50 is connected to the moving component 20, and the other end is connected to the support protrusion 301. When the fixing component 30 drives the moving component 20 to move, the suspension wire 50 can limit the moving component 20 within a preset range of the housing 10. The suspension wire 50 has an elastic restoring force, and the preset range can be determined according to the magnitude of the restoring force of the suspension wire 50.

[0049] like Figure 1 As shown, in the related technology, one end of the suspension wire 50 is connected to the moving component 20, and the other end of the suspension wire 50 is connected to the bottom of the fixed component 30. In this application, one end of the suspension wire 50 is connected to the moving component 20, and the other end of the suspension wire 50 is connected to the support protrusion 301. Therefore, the image stabilization module of this embodiment reduces the overall height of the image stabilization module while maintaining the length of the suspension wire 50, thereby ensuring elastic restoring force for the OIS section and allowing the moving component 20 to move within a preset range within the housing 10.

[0050] As can be seen, the image stabilization module provided in this application includes a housing 10, a fixed component 30, a movable component 20, and a circuit board 40 disposed within the housing 10. The fixed component 30 is connected to the housing 10 and can drive the movable component 20 to move within the housing 10. The movable component 20 is disposed on a first side 31 of the fixed component 30, and the circuit board 40 is disposed on a second side 32 of the fixed component 30. The first side 31 and the second side 32 are opposite sides, with the second side 32 closer to the opening side of the housing 10. The fixed component 30 has at least one support protrusion 301 on the second side 32. The plane of the circuit board 40 that contacts the second side 32 has a first linear distance to the first side 31, and the side of the support protrusion 301 away from the fixed component 30 has a second linear distance to the first side 31, the second linear distance being greater than the first linear distance. One end of the suspension wire 50 is connected to the moving component 20, and the other end is connected to the support protrusion 301. When the fixed component 30 drives the moving component 20 to move, the suspension wire 50 can support the moving component 20 to perform anti-shaking motion relative to the fixed component 30.

[0051] Because one end of the suspension wire 50 is connected to the support protrusion 301, and the first linear distance is greater than the second linear distance, the bottom of the fixing component 30 and the support protrusion 301 form a groove. The circuit board 40 is disposed in the groove formed by the support protrusion 301. This structure can ensure the length of the suspension wire and reduce the height of the fixed component 30 and the circuit board 40 stacked together, thereby reducing the height of the entire image stabilization module and shrinking the size of the image stabilization module, thus meeting the requirement of shrinking the size of electronic devices.

[0052] Figure 5 yes Figure 3 Enlarged view of region A in the image. Figure 6 This is a schematic exploded view of the movable component of the image stabilization module provided in an embodiment of this application. In some embodiments, the movable component 20 includes a movable bracket 201, a first spring 202, a second spring 203, and a lens bracket 204. The movable bracket 201 surrounds the lens bracket 204, that is, the movable bracket 201 is sleeved on the outside of the lens bracket 204.

[0053] The first spring 202 is disposed on the third side 2041 of the lens bracket 204, and the second spring 203 is disposed on the fourth side 2042 of the lens bracket 204. The third side 2041 and the fourth side 2042 are opposite sides, and the fourth side 2042 is close to the fixing component 30. The first spring 202 and the second spring 203 are both fixedly connected to the lens bracket 204, and the first spring 202 and the second spring 203 are both fixedly connected to the movable bracket 201.

[0054] In other words, the first spring 202 and the second spring 203 are fixedly connected to the movable bracket 201, which can be achieved through a combination of hot riveting and adhesive bonding. Similarly, the first spring 202 and the second spring 203 are fixedly connected to the lens bracket 204, again through a combination of hot riveting and adhesive bonding. Furthermore, there is a gap between the lens bracket 204 and the movable bracket 201, and the first spring 202 and the second spring 203 are elastic. Therefore, the first spring 202 and the second spring 203 can drive the lens bracket 204 to move within the movable bracket 201.

[0055] like Figure 5 The suspension wire 50 is connected to the first spring piece 202, specifically by welding. One end of the suspension wire 50 is electrically connected to the first spring piece 202, and the other end of the suspension wire 50 is connected to the support protrusion 301.

[0056] Figure 7 This is a schematic exploded view of the fixing component 30 of the image stabilization module provided in this application embodiment. In some embodiments, such as Figure 7As shown, the fixing component 30 includes a fixing bracket 302 and a metal wire 303. The metal wire 303 is disposed in the fixing bracket 302. Specifically, a portion of the metal wire 303 may be disposed inside the fixing bracket 302, meaning that the fixing bracket 302 partially encloses the metal wire 303, with a portion of the metal wire 303 protruding for electrical connection with other components. The support protrusion 301 may be disposed on the fixing bracket 302.

[0057] In some embodiments, the fixing bracket 302 and the metal circuit 303 can be integrated together using an insert-molding process. Furthermore, as... Figure 7 As shown, the OISIC (Optical Image Stabilizer) 3031 and / or Hall IC (Hall Integrated Circuit) 3032 can be placed on the metal line 303. This not only enables the metal line 303 to have signal communication attributes, but also makes full use of the installation space of the metal line 303, making the device installation more compact and further reducing the size of the image stabilization module.

[0058] like Figure 5 and Figure 7 As shown, the fixed bracket 302 has a through hole 3021, and the support protrusion 301 has a first receiving cavity 3011. The through hole 3021 communicates with the first receiving cavity 3011, and one end of the suspension wire 50 extends through the through hole 3021 into the first receiving cavity 3011. A portion of the metal circuit 303 can be exposed and is disposed in the first receiving cavity 3011. Therefore, after one end of the suspension wire 50 extends through the through hole 3021 into the first receiving cavity 3011, it can be electrically connected to the metal circuit 303 within the first receiving cavity 3011, and the metal circuit 303 is electrically connected to the circuit board 40.

[0059] Since the metal line 303 is electrically connected to the circuit board 40, and the suspension wire 50 is also electrically connected to the metal line 303, an electrical connection between the suspension wire 50 and the metal line 303 can be achieved. Furthermore, since the suspension wire 50 is electrically connected to the first spring 202, a connection link can be formed between the first spring 202, the suspension wire 50, the metal line, and the circuit board 40.

[0060] like Figure 6 and Figure 7 As shown, the movable component 20 further includes a magnetic element 205, which is disposed on the movable bracket 201. The fixed component 30 further includes a first coil 304. The first coil 304 is disposed on the fixed bracket 302 and electrically connected to the metal line 303, which can be achieved by soldering. When the first coil 304 is energized, the force generated on the magnetic element 205 drives the movable component 20 to move in the housing 10 along a first direction or a second direction.

[0061] Since the metal line 303 is electrically connected to the circuit board 40, and the first coil 304 is electrically connected to the metal line 303, it is equivalent to the first coil 304 being electrically connected to the circuit board 40 through the metal line 303. The circuit board 40 is electrically connected to the main board, so the on / off state of the first coil 304 and the magnitude of the current can be controlled through the circuit board 40, thereby controlling the force generated on the magnetic component 205, and thus controlling the driving force generated on the moving component 20.

[0062] The first direction can be the X direction, and the second direction can be the Y direction. That is to say, the first coil 304 in the fixed component 30 can drive the moving component 20 to move relative to the fixed component 30 in the X direction or in the Y direction.

[0063] Alternatively, the first coil 304 can be a flexible circuit board coil (FP-coil), which can be directly attached to the mounting bracket 302. This also reduces the installation space of the first coil 304, thereby reducing the size of the image stabilization module. The first coil 304 and the metal circuit 303 inside the mounting bracket 302 can be electrically connected by soldering.

[0064] Figure 8 This is a schematic diagram showing the positional relationship between the moving component and the fixed component of the image stabilization module provided in this application embodiment when it is in a non-OIS state. Figure 9 This is a schematic diagram showing the positional relationship between the moving and fixed components of the image stabilization module provided in this application embodiment when it is in OIS state. Figure 8 As shown, when the first coil 304 is not energized, it does not exert any force on the magnetic component 205. Alternatively, when the current flowing through the first coil 304 is small, the force exerted by the first coil 304 on the magnetic component 205 is small. In this case, the first coil 304 cannot drive the moving component 20 to move relative to the fixed component 30 in the X and Y directions. At this time, the anti-shake module is in a non-OIS state.

[0065] When jitter is detected, the motherboard energizes the first coil 304 via circuit board 40, and sets the energizing current according to the required force (the specific algorithm is not detailed in this application). After the first coil 304 is energized, it exerts a force on the magnetic component 205, thereby driving the moving component 20 to move relative to the fixed component 30 in the X and Y directions, achieving the anti-shake function. At this time, the anti-shake module is in OIS (Optical Image Stabilization) state.

[0066] like Figure 8 and Figure 9As shown, the bottom of the fixed bracket in this application has a support protrusion. Since the suspension wire goes directly to the support protrusion, the height of the image stabilization module can be reduced while maintaining the length of the suspension wire, thereby ensuring the maximum tilt angle φ of the suspension wire, which in turn ensures the range of movement of the moving component 20 relative to the fixed component 30. Ultimately, this achieves both a reduction in the size of the image stabilization module and the normal operation of the image stabilization function.

[0067] In some implementations, such as Figure 6 As shown, the movable component 20 also includes a second coil 206, which is disposed on the lens bracket 204 and electrically connected to the first spring 202. Specifically, the second coil 206 can be embedded in the outside of the lens bracket 204 and then electrically connected to the first spring 202 through an internal wire. The method of electrical connection between the second coil 206 and the first spring 202 is not limited in this application. Since the first spring 202 is electrically connected to the metal circuit 303 through the suspension wire 50, and since the metal circuit 303 is electrically connected to the circuit board 40, the first spring 202 is electrically connected to the circuit board 40, and the second coil 206 is also electrically connected to the circuit board 40.

[0068] Circuit board 40 can be electrically connected to the main board via connector 401. Therefore, circuit board 40 can control the on / off state of the second coil 206 and the magnitude of the energized current, thereby controlling the force generated on the magnetic component 205 and thus the driving force generated on the lens bracket 204. When the second coil 206 is energized, the force generated on the magnetic component 205 can drive the lens bracket 204 to move in a third direction within the movable bracket 201.

[0069] The third direction can be the Z direction. That is, when the second coil 206 is energized, it can drive the lens bracket 204 to move in the Z direction within the movable bracket 201 by exerting a force on the magnetic component 205.

[0070] Figure 10 This is a schematic perspective view of a stabilization module provided in an embodiment of this application. Figure 11 This is a schematic perspective view of another image stabilization module provided in an embodiment of this application. In some implementations, such as... Figure 10As shown, the fixing component 30 has a support protrusion 301 at each of the four corners of the second side 32. The image stabilization module includes four suspension wires 50, which are connected to the corresponding support protrusions 301. The suspension wires 50 have a certain degree of elasticity, allowing the moving component 20 to overcome elastic movement during motion and increasing the linearity of the motion. The four suspension wires 50 enhance the support force on the moving component 20. Furthermore, since the four suspension wires 50 are distributed at the four corners of the moving component 20, the moving component 20 can move more flexibly throughout the entire internal range of the housing 10, thereby improving the image stabilization effect of the image stabilization component.

[0071] In some embodiments, the circuit board 40 is provided with a clearance structure 402 through which the support protrusion 301 passes, and the shape of the clearance structure 402 matches the shape of the support protrusion 301. For example... Figure 10 and Figure 11 As shown, the support protrusions 301 are located at the four corners of the fixed bracket 302, so four clearance structures 402 can be set at the corresponding positions at the four corners of the circuit board 40. This allows the support protrusions 301 to pass through the clearance structures 402, effectively embedding the circuit board 40 into the bottom of the fixed bracket 302. This achieves the effect of reducing the height of the image stabilization module.

[0072] Furthermore, the shape of the clearance structure 402 matches the shape of the support protrusion 301. For example, the cross-sectional shape of the support protrusion 301 is square, and the cross-sectional shape of the clearance structure 402 on the circuit board 40 is square of the same size. This avoids gaps between the circuit board 40 and the support protrusion 301, thereby preventing dust from entering the interior of the housing 10.

[0073] Secondly, embodiments of this application provide an electronic device, which includes a lens assembly and the image stabilization module described in the first aspect.
