Description

Technical Field

[0001] This application belongs to the field of electronic technology, and particularly relates to an imaging module and an electronic device. Background Art

[0002] Currently, cameras in electronic devices such as mobile phones are usually equipped with an optical image stabilization function. The conventional anti-shake methods are pitch anti-shake and yaw anti-shake. However, in the existing pitch anti-shake, the rotation center is the center point B on the reflection surface of the Optical Image Stabilizer (OIS). As Figure 1 shown, since the light exit surface is usually concave, the OIS with point B as the rotation center has a high sensitivity, poor lens resolution, and in this case, the relative displacement of the OIS sensing magnet relative to the Hall sensor is small, and the OIS sensing accuracy is low. Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide an imaging module and an electronic device, which can solve the problems that the existing pitch anti-shake function of electronic devices has a high OIS sensitivity, resulting in poor lens resolution and low OIS sensing accuracy.

[0005] A frame body;

[0006] A pitch anti-shake component, the pitch anti-shake component is arranged in the frame body, and the pitch anti-shake component includes an Optical Image Stabilizer (OIS), and at least two pitch rotation shafts located on both sides of the light exit surface of the OIS. The at least two pitch rotation shafts support the OIS, so that the center point of the light exit surface is the rotation center for the pitch anti-shake of the pitch anti-shake component.

[0007] In a second aspect, the embodiments of this application provide an electronic device, including the imaging module described in the first aspect.

[0008] In the embodiment of the present application, the camera module includes: a frame body; a forward-tilt Pitch anti-shake component, the Pitch anti-shake component is disposed in the frame body, and the Pitch anti-shake component includes an optical image stabilizer (OIS), and at least two Pitch rotation shafts located on both sides of the light-emitting surface of the OIS, the at least two Pitch rotation shafts support the OIS, so that the center point of the light-emitting surface is the rotation center for Pitch anti-shake of the Pitch anti-shake component. In this way, through the improved design of the rotation center point of the Pitch anti-shake in the embodiment of the present application, the rotation center of the Pitch anti-shake is changed from the original point B to the center point of the light-emitting surface, which can effectively reduce the sensitivity of the OIS, improve the lens resolution, and increase the relative displacement amount between the sensing magnet and the Hall sensor, thereby increasing the Hall sensitivity and improving the OIS sensing accuracy.

[0025] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] To make the embodiments of the present application clearer, the following first introduces the relevant technical knowledge involved in the embodiments of the present application:

[0027] In the prior art, the camera module in an electronic device usually adopts the conventional OIS anti-shake method of pitch plus yaw. And as Figure 1 shown, when the camera module performs pitch anti-shake, the rotation center is the center point B of the reflecting surface of the OIS group. Here, the OIS sensitivity is relatively high, resulting in a poor lens resolution, that is, a poor Modulation Transfer Function (MTF) value.

[0028] For the telephoto cameras of current electronic devices such as mobile phones, in order to increase the aperture and reduce the size of the camera module, a reflecting component with a dioptric power is adopted, that is, a power prism (PP). The inventor found that as the dioptric power of the PP increases, the rotation center with the lowest OIS sensitivity will move from Figure 1 the B point shown to the light exit surface C point. Therefore, to reduce the OIS sensitivity, it is necessary to move the rotation center of pitch to the center point C of the light exit surface of the power prism.

[0029] In addition, the relative displacement of the OIS sensing magnet centered on the B point relative to the Hall sensor is small, and the OIS sensing accuracy is relatively low. As Figure 2 shown, the movement trajectory 1 is the trajectory of the sensing magnet rotating around the C point, and the movement trajectory 2 is the trajectory of the sensing magnet rotating around the B point. It can be seen that when rotating the same angle, the displacement of the sensing magnet rotating around the C point relative to the Hall sensor is greater than the displacement of the sensing magnet rotating around the B point relative to the Hall sensor, that is, the magnetic flux change amount is larger and the sensitivity is improved. Therefore, moving the rotation center of pitch to the C point can also improve the OIS sensing accuracy.

[0030] Since the light-emitting surface of the OIS needs to ensure normal light emission, there is little space for the camera module to rotate around the fulcrum of this surface, so it is difficult for the camera module to use point C of the light-emitting surface as the rotation center. In the embodiment of the present application, the difficulties of the prior art are overcome, and it is proposed to set pitch rotation axes on both sides of the light-emitting surface of the OIS group to support the OIS group, so that the OIS group can rotate around the pitch rotation axis to achieve the pitch anti-shake function, and the rotation center is transferred to the light-emitting surface, thereby reducing the sensitivity of the OIS and improving the sensing accuracy of the OIS.

[0031] The camera module provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0032] See also Figure 3 , Figure 3 This is a schematic diagram of the exploded structure of the camera module provided in the embodiment of the present application. Figure 3 As shown, the camera module includes:

[0033] Frame body 10;

[0034] A forward-leaning Pitch anti-shake component is arranged in the frame body 10, and the Pitch anti-shake component includes an optical image stabilizer OIS21, and at least two Pitch shafts 22 located on both sides of the light-emitting surface 20 of the OIS21, and the at least two Pitch shafts 22 are supported by the OIS21, so that the center point of the light-emitting surface 20 is the rotation center of the Pitch anti-shake component for Pitch anti-shake.

[0035] The frame body 10 may also be called Housing, which is used for structural support, and the Pitch anti-shake component is arranged in the frame body 10 .

[0036] The Pitch anti-shake component is a component for realizing the Pitch anti-shake function, and mainly includes OIS21 and Pitch shaft 22. The function of OIS21 is to stabilize the camera lens through a physical mechanism to solve the image blur problem caused by shaking when taking pictures and recording videos. The Pitch shaft 22 is used to support OIS21 so that it rubs on the Pitch shaft 22 and rotates OIS21 around the Pitch shaft 22 to perform the Pitch anti-shake action. Here, supporting can be understood as supporting and clamping.

[0037] In the embodiments of the present application, at least two Pitch rotating shafts 22 can be respectively arranged on both sides of the light-emitting surface 20 of the OIS 21. Exemplarily, one Pitch rotating shaft 22 can be respectively arranged on both sides of the light-emitting surface 20 of the OIS 21, so that the OIS 21 can be stable under the clamping action of the two Pitch rotating shafts 22 on both sides and can rotate around the Pitch rotating shaft 22. Since the Pitch rotating shafts 22 are arranged on both sides parallel to the light-emitting surface 20 of the OIS 21, therefore, when the Pitch anti-shake component performs Pitch anti-shake, the rotation center is located at the center point of the light-emitting surface 20, that is Figure 1 the C point shown.

[0038] It should be noted that some other necessary circuit components can also be arranged in the camera module, such as a printed circuit board (PCB), a flexible printed circuit (FPC), a coil, etc., for realizing electrical connection of some components in the camera module and electrical connection with the main board of the electronic device, which will not be described in detail here. The frame body 10 can also be used for attaching the FPC, bonding guide rods, rotating shafts, elastic pieces, holders, infrared filters (IR filters), etc.

[0039] According to some embodiments of the present application, as Figure 3 shown, the camera module further includes:

[0040] A rotating Roll anti-shake component, the Roll anti-shake component is arranged in the frame body 10, the Roll anti-shake component includes a Roll carrier 31 and a Roll rotating shaft 32, the Roll rotating shaft 32 is arranged perpendicular to the Pitch rotating shaft 22, the Roll rotating shaft 32 is arranged in the rotating shaft groove of the frame body 10, and the Roll rotating shaft 32 supports the Roll carrier 31.

[0041] That is, in some embodiments, considering that the conventional OIS anti-shake method of Pitch plus Yaw will cause the MTF to deteriorate, that is, the lens resolution will deteriorate, so in order not to affect the MTF effect, the Yaw anti-shake method can be changed to the Roll anti-shake method. Among them, the Pitch axis, the Yaw axis and the Roll axis are respectively as Figure 3 and Figure 4 shown. In the embodiments of the present application, the OIS 21 can rotate around the Pitch axis to perform Pitch anti-shake, or can rotate around the Roll axis to perform Roll anti-shake.

[0042] Specifically, the Roll anti-shake component is arranged in the frame body 10, and the Roll anti-shake component is a component for realizing the Roll anti-shake function, such as Figure 3As shown, it mainly includes a Roll carrier 31 and a Roll rotating shaft 32. Among them, the Roll carrier 31 is used to carry the Pitch rotating shaft 22. The Roll rotating shaft 32 is arranged in the rotating shaft groove of the frame body 10. Specifically, a support column is provided in the frame body 10, and a Roll rotating shaft groove is provided on the support column. The Roll rotating shaft 32 is installed in the Roll rotating shaft groove, and the Roll rotating shaft 32 and the Pitch rotating shaft 22 are arranged perpendicular to each other. The rotation center of Roll anti-shake is the optical axis center. The Roll rotating shaft 32 is used to support the Roll carrier 31, so that it rubs on the Roll rotating shaft 32, and the Roll carrier 31 rotates around the Roll rotating shaft 32 to perform the Roll anti-shake action. Here, "support" can be understood as "support".

[0043] In this way, by changing the OIS anti-shake method of Yaw to the anti-shake method of Roll, the lens resolution can be improved.

[0044] Furthermore, as Figure 3 shown, the OIS 21 includes an optical prism carrier 211 and an optical prism 212. The optical prism 212 is installed on the optical prism carrier 211;

[0045] The optical prism carrier 211 is installed on the Roll carrier 31. The at least two Pitch rotating shafts 22 are respectively arranged in the rotating shaft grooves on both sides of the Roll carrier 31, so that the at least two Pitch rotating shafts 22 are respectively located on both sides of the light exit surface 20 of the OIS 21.

[0046] As Figure 3 shown, the OIS 21 may include an optical prism carrier 211 and an optical prism 212. The optical prism carrier 211 is provided with a groove that can accommodate the optical prism 212, so that the optical prism 212 can be installed in the groove of the optical prism carrier 211.

[0047] The optical prism carrier 211 can be installed on the Roll carrier 31. For example, the lower part of the optical prism carrier 211 is adapted to the upper part of the Roll carrier 31, so that the optical prism carrier 211 can be just snapped onto the Roll carrier 31 and combined into one body. The Roll carrier 31 is provided with Pitch rotating shaft grooves on both sides corresponding to the light exit surface 20 of the optical prism 212, and the at least two Pitch rotating shafts 22 are respectively installed in the Pitch rotating shaft grooves on both sides of the Roll carrier 31, so that the at least two Pitch rotating shafts 22 support the optical prism carrier 211 and the Roll carrier 31.

[0048] It should be noted that the optical prism carrier 211 can be a power prism PP or an ordinary prism, that is, the OIS 21 structure in the embodiment of the present application can be a PP periscope or an ordinary prism periscope.

[0049] Through this embodiment, the OIS 21 and the Roll carrier 31 can be combined into one body, which is beneficial to saving the internal space of the camera module, and the Pitch rotating shaft 22 can be effectively fixed through the rotating shaft grooves on both sides of the Roll carrier 31 to achieve Pitch anti-shake.

[0050] According to some embodiments of the present application, as Figure 3 shown, the camera module further includes:

[0051] A flexible printed circuit board FPC 40, and the FPC 40 is bonded to the periphery of the frame body 10;

[0052] A first coil 51, and the first coil 51 is disposed on the FPC 40;

[0053] A first magnet 61, and the first magnet 61 is bonded to the optical prism carrier 211. The first magnet 61 interacts with the first coil 51 to generate an electromagnetic field, and the first coil 51 generates a Lorentz force under the action of the electromagnetic field to drive the optical prism carrier 211 to perform Pitch anti-shake movement;

[0054] A second magnet 62, and the second magnet 62 is bonded to the support column of the frame body 10;

[0055] Wherein, the second magnet 62 and the first magnet 61 generate a repulsive force under the interaction of the magnetic fields, so that the optical prism carrier 211 is adsorbed on the Roll carrier 31.

[0056] Specifically, the first magnet 61 can also be called the Pitch driving magnet, and the optical prism carrier 211 can be used as the Pitch driving magnet bracket. The Pitch driving magnet is bonded to the optical prism carrier 211. The first coil 51 can also be called the Pitch coil and can be welded to the FPC 40. The Pitch driving magnet generates a stable electromagnetic field when the Pitch coil is energized, and the Pitch coil generates a Lorentz force under the action of the electromagnetic field to drive the optical prism carrier 211 to perform Pitch anti-shake movement around the Pitch rotating shaft 22.

[0057] The second magnet 62 can also be called the Pitch adsorption magnet and is bonded to the support column of the frame body 10. The Pitch adsorption magnet and the pitch driving magnet generate a repulsive force under the interaction of the magnetic fields, so that the optical prism carrier 211 is adsorbed on the Roll carrier 31.

[0058] The flexible printed circuit board FPC40 is bonded to the periphery of the Housing. It should be noted that an FPC coil, a Hall sensor, a Tunnel Magneto Resistance Sensor (TMR), etc. can also be soldered on the flexible printed circuit board FPC40. The FPC coil is used to conduct all other coils, Hall sensors, TMR and other electronic components.

[0059] In this way, in this embodiment, the Pitch driving magnet and the Pitch adsorption magnet fixed on the support column of the frame body 10 generate a repulsive force, and the optical prism carrier 211 is adsorbed on the Roll carrier 31 with the line formed by the at least two Pitch rotating shafts 22 as the fulcrum.

[0060] In addition, in some technologies, the OIS component is usually an electromagnetic ball structure. After being impacted by drops or collisions, it is prone to have pits that affect performance, and the Proportional-Integral-Derivative (PID) debugging is difficult, and the anti-shake effect is poor. In the embodiment of the present application, the Pitch anti-shake structure is changed from the original ball type to a guide rod with a magnetic attraction structure, which makes the PID easier to debug, the anti-shake effect is better, and the guide rod structure makes the Pitch anti-shake component have a much larger impact contact area than the ball structure under impact states such as drops, and the pressure is reduced, thereby improving the problem of abnormal characteristics caused by impact pits.

[0061] Figure 5 is the top view of the camera module, Figure 6 is the left view of the camera module, Figure 7 is along Figure 5 the sectional view taken along the line A-A' in Figure 8 is along Figure 6 the sectional view taken along the line B-B' in Figure 9 is along Figure 5 the sectional view taken along the line C-C' in. As Figure 7 and Figure 8 shown, two (i.e., 2 pcs) Pitch rotating shafts 22 are clamped on both sides of the optical prism carrier 211 and are respectively inserted into the Roll carrier rotating shaft groove 311, and the optical prism carrier 211 is buckled on the Roll carrier 31.

[0062] The two Pitch rotating shafts 22 are in the same plane as the light-emitting surface 20 of the optical prism carrier 211 and intersect with the optical center line of the optical prism carrier 211, as Figure 9As shown, the Pitch driving magnet, i.e., the first magnet 61, repels the adsorption magnet fixed on the Housing support column 11, i.e., the second magnet 62. The optical prism carrier 211 is adsorbed on the Roll carrier 31 with the line formed by two Pitch rotating shafts 22 as the fulcrum to perform Pitch movement.

[0063] According to some embodiments of the present application, as Figure 3 shown, the camera module further includes:

[0064] An FPC 40, which is bonded to the periphery of the frame body 10;

[0065] A second coil 52, which is arranged on the FPC 40;

[0066] A third magnet 63, which is bonded to the Roll carrier 31. The third magnet 63 interacts with the second coil 52 to generate an electromagnetic field, and the second coil 52 generates a Lorentz force under the action of the electromagnetic field to drive the Roll carrier 31 to perform Roll anti-shake movement.

[0067] Specifically, the third magnet 63 can also be called the Roll driving magnet, and the Roll carrier 31 can also serve as a Roll magnet bracket, that is, the Roll magnet can be bonded to the Roll carrier 31. In some embodiments, the number of Roll magnets can be two, which are respectively bonded to the opposite side surfaces of the Roll carrier 31.

[0068] The second coil 52 can also be called the Roll coil. In some embodiments, the number of Roll coils can also be two, which are respectively bonded to the opposite sides of the FPC 40. The Roll driving magnet generates a stable electromagnetic field when the Roll coil is energized, and the Roll coil generates a Lorentz force under the action of the electromagnetic field to drive the Roll carrier 31 to perform Roll anti-shake movement around the Roll rotating shaft 32.

[0069] In this way, through this implementation manner, the Roll anti-shake structure is a guide rod rotating shaft with a magnetic attraction structure, which makes the PID easier to debug and has a better anti-shake effect. Moreover, the guide rod structure greatly increases the impact contact area compared with the ball structure in the case of impacts such as drops of the Roll anti-shake component, reducing the pressure, thereby improving the problem of abnormal characteristics caused by impact pits.

[0070] According to some other embodiments of the present application, as Figure 3 shown, the camera module further includes:

[0071] A first elastic sheet 71, which is respectively connected to the bottom of the frame body 10 and the Roll carrier 31 to press the Roll carrier 31 against the Roll rotating shaft 32.

[0072] Among them, the first elastic piece 71, which can also be called a pressing elastic piece, is respectively bonded to the bottom of the frame body 10 and the Roll carrier 31. The Roll carrier 31 is pre-pressed on the Roll rotating shaft 32 through the pre-pressure of the elastic piece.

[0073] Specifically, as Figure 10 shown, 1 piece (i.e., 1 pcs) of Roll rotating shaft 32 is installed in the rotating shaft groove 12 on the Housing support column 11, and the Roll carrier 31 is buckled on the support column 11.

[0074] The Roll rotating shaft 32 coincides with the optical center line of the optical prism 212. As Figure 9 、 Figure 10 and Figure 11 shown, the Roll carrier 31 is connected to the bottom of the Housing through the pressing elastic piece, i.e., the first elastic piece 71. The Roll carrier 31 is pressed on the Roll rotating shaft 32 through sufficient pre-pressure. The Roll carrier 31 takes the line formed by the Roll rotating shaft 32 as the fulcrum and performs a Roll movement with the Roll rotating shaft 32 as the center.

[0075] In this way, through this embodiment, the Roll anti-shake structure is a guide rod rotating shaft with an elastic piece pre-pressing method, making the PID easier to debug (the stiffness of the elastic piece itself, the displacement is linearly related to the thrust, making it easier to debug), and the anti-shake effect is better.

[0076] According to some embodiments of the present application, as Figure 3 shown, the camera module further includes:

[0077] A main buffer 81, which is arranged on the Roll carrier 31;

[0078] A secondary buffer 82, which is arranged on the optical prism carrier 211;

[0079] Among them, the main buffer 81 and the secondary buffer 82 are used for stroke limiting of the Roll carrier 31 and the optical prism carrier 211 and impact limiting after derailment.

[0080] That is, in some embodiments, a buffer structure can also be set in the camera module to perform stroke limiting and impact limiting after derailment on the Roll carrier 31 and the optical prism carrier 211. And the Roll carrier 31 can be used as a bracket for the main buffer 81, and the main buffer 81 can be arranged on the Roll carrier 31. Exemplarily, as Figure 3 shown, the main buffer (Main Damper) 81 has two pins, which are inserted into the side of the Roll carrier 31. The number of the main buffers 81 can be 2, and one is inserted into each of the left and right sides of the Roll carrier 31.

[0081] The secondary damper (AS Damper) 82 is disposed on the optical prism carrier 211. The primary damper 81 and the secondary damper 82 together constitute the stroke limit and derailment impact structure of the Roll carrier 31 and the optical prism carrier 211, and both of them jointly perform stroke limit and impact limit after derailment on the Roll carrier 31 and the optical prism carrier 211.

[0082] Thus, through this embodiment, both the OIS stroke limit and the impact limit after derailment adopt the Damper structure, further improving the impact abnormal sound phenomenon under shaking and running states.

[0083] According to some embodiments of the present application, as Figure 3 、 Figure 12a and Figure 12b shown, the camera module further includes:

[0084] A lens assembly, the lens assembly includes a lens carrier 91, a lens, and a guide rod 92. The lens is mounted on the lens carrier 91, the guide rod 92 is bonded inside the frame body 10, and the guide rod 92 supports the lens carrier 91;

[0085] A second elastic sheet 72, the second elastic sheet 72 is mounted inside the frame body 10;

[0086] A first buffer 83, the first buffer 83 is mounted on the lens carrier 91;

[0087] A second buffer 84, the second buffer 84 is mounted inside the frame body 10;

[0088] Wherein, the second elastic sheet 72, the first buffer 83, and the second buffer 84 constitute a double buffer structure of the lens carrier 91.

[0089] In this embodiment, the lens assembly is an assembly for imaging, mainly including a lens carrier 91, a lens, and a guide rod 92. Among them, the lens carrier 91 is used to carry the lens, that is, the lens is mounted on the lens carrier 91, and the guide rod 92 is bonded inside the frame body 10 for supporting the lens carrier 91. For example, the guide rod 92 can penetrate through the lens carrier 91. Here, support can be understood as support.

[0090] The first buffer 83 can also be called a carrier Damper, and can be integrally formed with the lens carrier 91, or can be bonded to the lens carrier 91; the second buffer 84 can also be called a Housing Damper, and can be integrally formed with the frame body 10, or can be bonded to the frame body 10; the second elastic sheet 72 can also be called a buffer elastic sheet, and is mounted on the frame body 10. It can be formed by insert molding, or can be fixed by welding or gluing. The positional relationship of the carrier Damper, the Housing Damper, and the buffer elastic sheet is asFigure 12a and Figure 12b As shown in Figure 12b , the specific structures of the carrier Damper, Housing Damper and buffer shrapnel are as follows Figure 13 shown

[0091] The second shrapnel 72 and the first buffer 83 and the second buffer 84 together constitute a double buffer structure of the lens carrier 91, which is used to protect the lens carrier 91 from adverse effects such as shaking or impact. Specifically, when being impacted, the carrier Damper first impacts with the buffer shrapnel. After the buffer shrapnel is compressed and deformed, the Housing Damper then impacts with the lens carrier 91 to achieve the purpose of double buffering

[0092] In this way, in this embodiment, the mechanical limit of the lens assembly adopts a double buffer structure of shrapnel plus Damper flexible buffer material, which further improves the impact abnormal sound phenomenon of the camera module under shaking and running states

[0093] It should be noted that the lens assembly can be a single-group lens assembly, or two groups or multiple groups of lens assemblies. That is, the Damper structure of OIS and the double buffer structure of the lens assembly provided in the embodiments of the present application are not limited to continuous optical zoom periscopes (achieving zooming and focusing effects by moving two groups or multiple groups of lens groups), and are also applicable to periscopes with single-group fixed focus (only moving one group of lenses and the focal length does not change)

[0094] Furthermore, the lens assembly includes an automatic focus (AF) lens assembly and a zoom lens assembly

[0095] That is, in some embodiments, the embodiments of the present application can be applied to continuous optical zoom periscopes including AF lens assemblies and zoom lens assemblies, such as Figure 3 shown, the AF lens assembly includes an AF lens carrier 911 and an AF lens mounted on the AF lens carrier 911, and the zoom lens assembly includes a zoom lens carrier 912 and a zoom lens mounted on the zoom lens carrier 912. And corresponding carrier Damper and Housing Damper (i.e., AF Damper 841) are provided on the AF lens carrier 911, and corresponding carrier Damper and Housing Damper (i.e., Zoom Damper 842) are provided on the zoom lens carrier 912

[0096] According to some other embodiments of the present application, the lens assembly may also adopt a guide rod combined with a magnetic structure. Specifically, the AF lens carrier 911 can also serve as a magnet bracket. That is, an AF driving magnet 64 can be bonded to the AF lens carrier 911, and an AF coil 53 is welded to the FPC 40. When the AF coil 53 is energized, it interacts with the AF driving magnet 64 to generate a stable magnetic field.

[0097] Similarly, the Zoom lens carrier 912 can also serve as a magnet bracket. That is, a Zoom driving magnet 65 is bonded to the Zoom lens carrier 912, and a Zoom coil 54 is welded to the FPC 40. When the Zoom coil 54 is energized, it interacts with the Zoom driving magnet 65 to generate a stable magnetic field.

[0098] It should also be noted that as Figure 3 shown, the camera module may further include a housing 100, which can also be called the motor upper cover, covering above the frame body 10, serving to protect the OIS, lens, motor moving components and having a limiting function.

[0099] According to the above embodiments, it can be seen that the embodiments of the present application have the following advantages:

[0100] Changing the OIS anti-shake method of Yaw to the anti-shake method of Roll, and changing the Pitch rotation center from point B to point C effectively reduces the OIS sensitivity and improves the MTF value;

[0101] After the Pitch rotation center is changed from point B to point C, the Hall sensitivity is increased and the OIS sensing accuracy is improved;

[0102] The Pitch anti-shake structure is changed from the ball type to a guide rod combined with a magnetic structure, and the Roll anti-shake structure is a guide rod rotating shaft combined with a shrapnel preloading method, making the PID easier to debug, with a better anti-shake effect, and improving the problem of abnormal characteristics caused by impact pits;

[0103] Both the OIS stroke limit and the impact limit after derailment adopt the Damper structure, and the AF and Zoom lens mechanical limits adopt a double-buffer structure of shrapnel plus Damper flexible buffer material, further improving the impact abnormal sound phenomenon under shaking and running states.

[0104] The camera module in the embodiment of the present application includes: a frame body; a forward-tilt Pitch anti-shake component, the Pitch anti-shake component is disposed in the frame body, and the Pitch anti-shake component includes an optical image stabilizer (OIS), and at least two Pitch rotation shafts located on both sides of the light-emitting surface of the OIS, the at least two Pitch rotation shafts support the OIS, so that the center point of the light-emitting surface is the rotation center for the Pitch anti-shake of the Pitch anti-shake component. In this way, through the improved design of the rotation center point of the Pitch anti-shake in the embodiment of the present application, the rotation center of the Pitch anti-shake is changed from the original point B to the center point of the light-emitting surface, which can effectively reduce the OIS sensitivity, improve the lens resolution, and increase the relative displacement amount between the sensing magnet and the Hall sensor, thereby increasing the Hall sensitivity and improving the OIS sensing accuracy.
