Abstract
Description
[0001] This application claims the priority of a Chinese patent application with an application number of 202210394856.6 and an application title of "Camera Module and Electronic Device", which was filed with the Chinese Patent Office on April 15, 2022, and the entire content of which is incorporated herein by reference. Technical Field
[0002] Embodiments of the present application relate to the field of electronic devices, and more particularly, to a camera module and an electronic device. Background Art
[0003] An electronic device may be configured with a camera module having a pop-up function, where the camera module may have the functions of popping up and retracting. When the camera module is not enabled, the camera module may be housed within the electronic device. When an image needs to be captured, the camera module may partially pop out of the electronic device, enabling the camera module to focus within a relatively long range to meet diverse shooting requirements. However, the camera module having a pop-up function means that components for driving the pop-up and retraction of the camera module need to be added inside the camera module, which may increase the overall occupied space of the camera module. During the pop-up and retraction processes of the camera module, multiple components inside the camera module may move. How to make the multiple components move along the optical axis as much as possible and reduce the impact of the movement of the multiple components on the shooting performance of the camera module is a problem that needs to be solved. Summary of the Invention
[0004] Embodiments of the present application provide a camera module and an electronic device, aiming to enable the camera module to have excellent shooting performance and a relatively small occupied space.
[0005] In a first aspect, a camera module is provided, including:
[0006] A camera bracket;
[0007] A lens assembly, the lens assembly including a plurality of lenses arranged along the optical axis, and the lens assembly being located on one side of the camera bracket;
[0008] A pop-up pusher, the pop-up pusher being fixedly connected to the lens assembly;
[0009] A pop-up driving member, the pop-up driving member being carried on the camera bracket, and the pop-up driving member being configured to reciprocate along the optical axis to drive the pop-up pusher to move along the optical axis and drive the lens assembly to move along the optical axis relative to the camera bracket;
[0010] A pop-up cover, the pop-up cover being fixedly connected to the lens assembly, and a cavity formed by the pop-up cover and the camera bracket being configured to accommodate the lens assembly, the pop-up driving member, and the pop-up pusher;
[0011] A flexible connecting piece, which is hermetically connected between the pop-up cover and the camera bracket.
[0012] In the embodiment of popping up the lens by a stepper motor, the stepper motor and related speed-changing transmission components etc. occupy a relatively large space. In addition, the stepper motor rotates the lens to move the lens along the optical axis. During the process of the stepper motor rotating the lens, it is very difficult to control the displacement amount of the lens deviating from the optical axis. A camera module usually has a relatively large number of lenses. Then, during the popping-up process, it is relatively difficult to align the centers of multiple lenses, thereby affecting the imaging effect. The stepper motor is also prone to introducing noise, affecting the video shooting quality.
[0013] In the embodiment of popping up the lens by a Hall magnet, when the space occupied by the Hall magnet is reasonable, the stroke that the Hall magnet can achieve is relatively short. To meet the stroke requirement, multiple Hall magnets can be arranged in the camera module, which may further increase the space occupied by the camera module. Moreover, multiple Hall magnets may interfere with each other. By driving with a Hall magnet, a self-locking module needs to be additionally arranged, which may further increase the space occupied by the camera module.
[0014] In the solution provided by this application, by configuring a pop-up driving piece and a pop-up pushing piece that apply the piezoelectric principle, multiple lenses of the camera module can be popped up. Since the pop-up pushing piece mainly moves in a straight line by itself, it is relatively easy to control and reduce the displacement of multiple lenses deviating from the optical axis. The pop-up driving piece and the pop-up pushing piece can also relatively easily achieve a relatively long stroke. The pop-up driving piece and the pop-up pushing piece can also have a relatively small occupied space. In summary, the solution provided by this application is beneficial to making the camera module have excellent shooting performance and a relatively small occupied space. The pop-up driving piece and the pop-up pushing piece that apply the piezoelectric principle can have relatively small noise. By providing a pop-up cover and a flexible connecting piece, it is beneficial to reduce the entry of external pollutants into the camera module. In one embodiment, the pop-up driving piece may include a piezoelectric ceramic. The pop-up driving piece and the pop-up pushing piece can form a piezoelectric motor.
[0015] In combination with the first aspect, in some implementation manners of the first aspect, the lens assembly includes a focusing stator, a focusing mover, a focusing driving piece, and a focusing pushing piece. A lens is arranged on the focusing mover. The focusing driving piece is carried on the focusing stator. The focusing pushing piece is fixedly connected to the focusing mover. The focusing driving piece is used to reciprocally vibrate along the optical axis to drive the focusing pushing piece to move along the optical axis and drive the focusing mover to move relative to the focusing stator along the optical axis.
[0016] In an embodiment where a stepping motor is used to eject a lens, the stepping motor and related variable-speed transmission components, etc. occupy a relatively large space. Additionally, the stepping motor rotates the lens to move the lens along the optical axis. During the process of the stepping motor rotating the lens, it is very difficult to control the displacement amount of the lens deviating from the optical axis. A camera module usually has a relatively large number of lenses. During the ejection process, it is relatively difficult to align the centers of multiple lenses, which in turn affects the imaging effect. The stepping motor is also prone to introducing noise, affecting the video shooting quality.
[0017] In an embodiment where a Hall magnet is used to eject a lens, when the space occupied by the Hall magnet is reasonable, the stroke that the Hall magnet can achieve is relatively short. To meet the stroke requirement, multiple Hall magnets can be arranged in the camera module, which may further increase the space occupied by the camera module. Moreover, multiple Hall magnets may interfere with each other. When driven by the Hall magnet, an additional self-locking module needs to be set, which may further increase the space occupied by the camera module.
[0018] In the solution provided in this application, by configuring a focusing drive member and a focusing pusher that apply the piezoelectric principle, multiple lenses of the camera module can be focused. Since the focusing pusher mainly moves linearly by itself, it is relatively easy to control and reduce the displacement of multiple lenses deviating from the optical axis. The focusing drive member and the focusing pusher can also relatively easily achieve a relatively long stroke. The focusing drive member and the focusing pusher can also have a relatively small occupied space. In summary, the solution provided in this application is beneficial for the camera module to have excellent shooting performance and a relatively small occupied space. The focusing drive member and the focusing pusher that apply the piezoelectric principle can have relatively low noise. In one embodiment, the focusing drive member can include a piezoelectric ceramic. The focusing drive member and the focusing pusher can form a piezoelectric motor.
[0019] In combination with the first aspect, in some implementation manners of the first aspect, a first magnet is disposed on the focusing stator, and a second magnet that interacts with the first magnet is disposed on the focusing mover.
[0020] Due to the interaction between the first magnet and the second magnet, when the focusing mover moves relative to the focusing stator, the focusing mover can always be biased towards one side of the focusing stator, which is beneficial for reducing the displacement amount of the focusing mover deviating from the optical axis. Multiple lenses are disposed on the focusing assembly. Multiple lenses can always be biased towards one side of the focusing stator, and the displacement amount of multiple lenses deviating from the optical axis can be relatively small.
[0021] In combination with the first aspect, in some implementation manners of the first aspect, the focusing stator includes a guiding groove and a first magnet receiving groove. The guiding groove extends along the optical axis, the first magnet receiving groove communicates with the guiding groove, and the first magnet is disposed in the first magnet receiving groove;
[0022] The focusing mover includes a platform portion and a first extension bar. The platform portion is disposed perpendicular to the optical axis. The first extension bar extends from the platform portion toward the focusing stator and is received in the guiding groove. The second magnet is disposed on the first extension bar.
[0023] The second extension bar and the guiding groove can be used to guide the focusing stator and the focusing mover, which is beneficial to reducing the displacement amount of multiple lenses deviating from the optical axis. Disposing the magnet in the groove of the focusing stator is beneficial to reducing the occupied space.
[0024] Combined with the first aspect, in some implementation manners of the first aspect, a third magnet is disposed on the focusing stator, and a fourth magnet interacting with the third magnet is disposed on the camera bracket.
[0025] In some embodiments, the third magnet is disposed on a side of the focusing stator close to the camera bracket; the camera bracket further includes a third protruding portion, and the fourth magnet is disposed on the third protruding portion, and the fourth magnet extends along the optical axis.
[0026] In some embodiments, the azimuth angles of the third magnet and the first magnet relative to the optical axis are 0° to 15° or 165° to 180°.
[0027] Due to the interaction between the third magnet and the fourth magnet, when the focusing stator moves along the optical axis, the focusing stator can always be biased toward a certain side of the camera bracket, which is beneficial to reducing the displacement amount of the focusing stator deviating from the optical axis. Also, since a plurality of lenses are disposed on the focusing stator, the plurality of lenses can always be biased toward a certain side of the camera module, and the displacement amount of the plurality of lenses deviating from the optical axis can be relatively small.
[0028] Combined with the first aspect, in some implementation manners of the first aspect, the focusing stator includes a first lens receiving cavity, and a first part of the plurality of lenses is received in the first lens receiving cavity. The focusing mover includes a second lens receiving cavity, and a second part of the plurality of lenses is received in the second lens receiving cavity.
[0029] In a macro scenario, the distance between the camera module and the person being photographed is relatively small. Compared with the overall focusing of the plurality of lenses, the plurality of lenses are divided into a first part of the lenses and a second part of the lenses, so that a part of the lenses can be focused separately, which is beneficial to improving the viewing angle in the macro scenario. Therefore, within the effective focusing range of the camera module, the distance between the camera module and the person being photographed can be relatively small.
[0030] In some embodiments, the focusing mover is located between the focusing stator and the camera bracket.
[0031] The focusing mover is between the focusing stator and the camera bracket, which means the focusing mover moves between the focusing stator and the camera bracket. Since the focusing mover moves inside the camera module, the sealing and protecting structure outside the camera module can be relatively stationary during focusing, which is beneficial to reducing the possibility of external pollutants entering in the focusing state.
[0032] In combination with the first aspect, in some implementation manners of the first aspect, a first lens, a second lens and a lens barrel are disposed in the first lens accommodating cavity, the first lens is disposed outside the lens barrel, and the second lens is accommodated in the lens barrel.
[0033] The first lens can be disposed outside the lens barrel, so the number of lenses to be installed in the lens barrel is relatively small, which is beneficial to reducing the outer diameter of the lens barrel, and further beneficial to reducing the occupied space of the first part of the lenses in the focusing stator.
[0034] The spaced space between the first lens and the first lens accommodating cavity can be used to accommodate the colloid, which is beneficial to reducing the possibility of the colloid overflowing at the joint between the first lens and the opening of the lens cover.
[0035] In combination with the first aspect, in some implementation manners of the first aspect, a lens cover is further accommodated in the first lens accommodating cavity, and the first lens is clamped between the lens barrel and the lens cover.
[0036] Since the first lens can be clamped between the lens barrel and the lens cover, the combination of the lens barrel and the lens cover can be beneficial to strengthening the fixing stability of the first lens in the first lens accommodating cavity and beneficial to preventing the first lens from falling off the lens barrel. In some embodiments, the focusing stator has an avoidance recess structure for the ejecting driving member.
[0037] In combination with the first aspect, in some implementation manners of the first aspect, the focusing driving member includes a focusing pusher accommodating hole extending along the optical axis;
[0038] The focusing pusher extends along the optical axis, the focusing pusher is accommodated in the focusing pusher accommodating hole and abuts against the hole wall of the focusing pusher accommodating hole.
[0039] Controlling the frictional force between the focusing pusher accommodating hole and the focusing pusher as static frictional force can realize the hovering of the focusing pusher relative to the focusing driving member; controlling the frictional force between the focusing pusher accommodating hole and the focusing pusher as dynamic frictional force can realize the movement of the focusing driving member driving the focusing pusher.
[0040] In some embodiments, the focusing stator includes a focusing driving accommodating hole, and the focusing driving member is accommodated in the focusing driving accommodating hole.
[0041] In some embodiments, the focusing mover includes a platform portion which is disposed perpendicular to the optical axis. The focusing driver includes a first focusing pusher receiving hole and a second focusing pusher receiving hole. The first focusing pusher receiving hole and the second focusing pusher receiving hole extend along the optical axis and communicate with each other. The first focusing pusher receiving hole is located on a side of the focusing driver close to the platform portion, and the second focusing pusher receiving hole is located on a side of the focusing driver away from the platform portion. The aperture of the second focusing pusher receiving hole is larger than that of the first focusing pusher receiving hole. The focusing pusher is received in the first focusing pusher receiving hole and abuts against the hole wall of the first focusing pusher receiving hole. The focusing pusher extends out of the first focusing pusher receiving hole and is fixedly connected to the platform portion.
[0042] In some embodiments, the focusing pusher has a slit extending along the optical axis.
[0043] When the focusing pusher is not received in the first focusing pusher receiving hole of the focusing driver, the slit of the focusing pusher can be relatively large. When the focusing pusher is received in the first focusing pusher receiving hole of the focusing driver, the focusing pusher is squeezed by the hole wall of the first focusing pusher receiving hole, so that the slit of the focusing pusher can be narrowed. This is beneficial to regulating the friction coefficient between the focusing pusher and the focusing driver, so that the focusing driver can drive the focusing pusher to move along the optical axis with an appropriate force.
[0044] In some embodiments, the azimuth angle between the focusing driver and the ejecting driver with respect to the optical axis is 15° to 180°.
[0045] Combined with the first aspect, in some implementation manners of the first aspect, the focusing stator includes a first circuit board receiving groove which extends from the side wall of the focusing stator to the focusing driver receiving hole;
[0046] The camera module further includes a first circuit board assembly. The first circuit board assembly includes a first circuit board portion and a second circuit board portion.

The second circuit board portion is disposed in the first circuit board receiving groove. The focusing control module is electrically connected to the focusing driver through the first circuit board portion and the second circuit board portion.
[0047] The first circuit board portion can partially extend into the receiving groove of the focusing stator. On the one hand, the focusing stator can provide mechanical protection for the first circuit board portion. On the other hand, it is beneficial to reduce the occupied space of the leads of the focusing driver in the camera module.
[0048] In combination with the first aspect, in some implementations of the first aspect, the focusing mover includes a platform portion and a second extension bar. The platform portion is disposed perpendicular to the optical axis. The second extension bar extends from the platform portion toward the focusing stator. A magnetic grating is fixed on the second extension bar, and the magnetic grating extends along the optical axis.
[0049] A magnetoresistive element is disposed on the first circuit board portion. The magnetoresistive element is disposed opposite to the magnetic grating, and the magnetoresistive element is used to detect the distance between the magnetic grating and the magnetoresistive element.
[0050] A magnetoresistive element is disposed on the first circuit board portion. The magnetoresistive element is disposed opposite to the magnetic grating, and the magnetoresistive element is used to detect the distance between the magnetic grating and the magnetoresistive element.
[0051] By disposing a magnetoresistive element on the focusing stator and a magnetic grating on the focusing mover, it is beneficial to determine and regulate the positional relationship between the focusing mover and the focusing stator, so as to quickly and accurately complete autofocusing.
[0052] In combination with the first aspect, in some implementations of the first aspect, the focusing stator is provided with a component receiving groove, and the second extension bar and the magnetic grating are received in the component receiving groove.
[0053] The focusing stator is provided with a component receiving groove, and the components of the first circuit board assembly and a part of the structure of the focusing mover are received in the component receiving groove, which is beneficial to assembling the first circuit board assembly, the focusing mover and the focusing stator together relatively compactly.

[0055] The displacement of the focusing driving member at the resonance zero point can be zero. The step of the focusing stator is opposite to the position near the resonance zero point on the focusing driving member, which is convenient for making the connection relationship between the focusing stator and the focusing driving member relatively stable.
[0056] In some embodiments, the focusing driving member and the focusing stator are connected by an elastic connecting member.
[0057] Since when the focusing driving member works, the part of the focusing driving member connected to the focusing stator may vibrate slightly back and forth along the optical axis. The focusing driving member and the focusing stator are connected by an elastic connecting member, and the elastic connecting member can absorb the vibration amount of the focusing driving member, which is beneficial to improving the connection stability between the focusing driving member and the focusing stator.
[0058] In combination with the first aspect, in certain implementations of the first aspect, a buffer is provided on a side of the platform portion facing and / or away from the focusing stator.
[0059] A buffer is arranged between the platform part and the focus stator. The buffer can buffer between the platform part and the focus stator, which is helpful to reduce the vibration generated by the collision between the platform part and the focus stator, and further reduce the impact on the components carried by the focus stator and the focus mover.
[0060] A buffer is provided between the platform part and the camera bracket, and the buffer can provide a buffer between the platform part and the camera bracket, thereby helping to reduce the vibration caused by the collision between the platform part and the camera bracket, thereby reducing the impact on the focus stator and the components carried by the camera bracket.
[0061] In combination with the first aspect, in some implementations of the first aspect, a fifth magnet is provided on a side wall of the focusing stator;
[0062] The camera module also includes a second circuit board assembly, which includes a third circuit board part. The third circuit board part is arranged parallel to the optical axis, and a displacement sensor is arranged on the third circuit board part. The displacement sensor is used to detect the distance between the fifth magnet and the displacement sensor.
[0063] When the fifth magnet is within the range of the displacement sensor, the positional relationship between the camera bracket and the focus stator can be determined and regulated based on the distance between the displacement sensor and the fifth magnet, which is beneficial for determining and regulating the positional relationship between the focus mover and the focus stator, so as to quickly and accurately complete the pop-up.
[0064] In some embodiments, the fifth magnet is located on a side of the focus stator away from the focus mover, or the fifth magnet is located on a side of the focus stator close to the focus mover.
[0065] The fifth magnet may correspond to the initial pop-up position or the final pop-up position of the camera module. By setting the fifth magnet and the displacement sensor, it is possible to determine whether the camera module has popped up to a specified height, or to determine whether the camera module has been retracted to a specified position, which is conducive to improving the stability of the camera module popping up and retracting.
[0066] In combination with the first aspect, in some implementations of the first aspect, the lens assembly further includes a focus stopper, wherein the focus stopper cooperates with an outer periphery of the focus stator and is fixedly connected to the focus mover.
[0067] Since the focus limiter surrounds the outer circumference of the focus stator, the focus limiter can limit the focus mover from multiple directions, which is beneficial to reducing the displacement of the focus mover from the optical axis.
[0068] In combination with the first aspect, in some implementations of the first aspect, the focusing stator includes a limiting groove that extends along the optical axis, and a limiting surface is provided on a side of the limiting groove close to the focusing mover.
[0069] The focusing limiting member includes a first limiting claw that extends into the limiting groove.
[0070] Wherein, the limiting surface is used to limit the first limiting claw.
[0071] By providing the limiting groove and the second limiting claw, it is beneficial to reduce the possibility of the focusing mover detaching excessively from the focusing stator.
[0072] In some embodiments, the second limiting claw is located on a side of the focusing limiting member away from the focusing mover.
[0073] The second limiting claw is located on a side of the focusing limiting member away from the focusing mover, so as to facilitate assembling the focusing limiting member and the focusing stator together from a side close to the ejecting cover.
[0074] In some embodiments, a buffer member is provided on the limiting surface.
[0075] The buffer member can buffer between the focusing limiting member and the focusing stator, which is beneficial to reducing the vibration generated by the impact between the focusing limiting member and the focusing stator, and further reducing the influence on the elements carried on the focusing mover and the focusing stator.
[0076] In combination with the first aspect, in some implementations of the first aspect, the focusing stator further includes a focusing guide hole, and the lens assembly further includes a focusing guide rod. The focusing guide hole and the focusing guide rod extend along the optical axis, and the focusing guide rod is received in the focusing guide hole and is fixedly connected to the focusing mover.
[0077] The focusing guide sleeve and the focusing guide rod can be used to guide multiple lenses, which is beneficial to reducing the displacement amount of the multiple lenses deviating from the optical axis.
[0078] In some embodiments, the azimuth angle of the focusing guide rod and the focusing driving member relative to the optical axis is 45° to 135°.
[0079] In combination with the first aspect, in some implementations of the first aspect, the ejecting driving member includes an ejecting push member receiving hole that extends along the optical axis;
[0080] The ejecting push member extends along the optical axis, and the ejecting push member is received in the ejecting push member receiving hole and abuts against the hole wall of the ejecting push member receiving hole.
[0081] Controlling the frictional force between the pop-up push member receiving hole and the pop-up push member to be static friction can enable the pop-up push member to hover relative to the pop-up driving member; controlling the frictional force between the pop-up push member receiving hole and the pop-up push member to be dynamic friction can enable the pop-up driving member to drive the pop-up push member to move.
[0082] In some embodiments, the pop-up driving member includes a first pop-up push member receiving hole and a second pop-up push member receiving hole.

The aperture of the second pop-up push member receiving hole is larger than the aperture of the first pop-up push member receiving hole;
[0083] The pop-up push member is received in the first pop-up push member receiving hole and abuts against the hole wall of the first pop-up push member receiving hole. One end of the pop-up push member away from the camera bracket extends out of the first pop-up push member receiving hole and is fixedly connected to the lens assembly.

[0086] In some embodiments, the mounting ears and the camera bracket are connected through an elastic connecting member.
[0087] Since the mounting ears may vibrate slightly along the optical axis when the pop-up driving member works. The mounting ears and the camera bracket are connected by an elastic connecting member, and the elastic connecting member can absorb the vibration amount of the mounting ears, which is beneficial to improving the connection stability between the pop-up driving member and the camera bracket.
[0088] In some embodiments, the pop-up push member has a slit extending along the optical axis.
[0089] When the ejection pusher is not placed in the first ejection pusher receiving hole of the ejection driving member, the gap of the ejection pusher can be relatively large. When the ejection pusher is placed in the first ejection pusher receiving hole of the ejection driving member, the ejection pusher is squeezed by the hole wall of the first ejection pusher receiving hole, so that the gap of the ejection pusher can be reduced. This is beneficial to regulating the friction coefficient between the ejection pusher and the ejection driving member, so that the ejection driving member can drive the ejection pusher to move along the optical axis with an appropriate force.
[0090] Combined with the first aspect, in some implementation manners of the first aspect, the camera bracket is provided with an ejection ring, and the ejection ring surrounds the outer periphery of the ejection driving member.
[0091] The ejection ring can be used to limit the displacement amount of the ejection driving member deviating from the optical axis, and thus is beneficial to reducing the displacement amount of the lens deviating from the optical axis.

[0096] The ejection cover further includes a first limiting claw, and the first limiting claw can slide in the claw sliding groove.
[0097] The first limiting claw can be limited by the limiting table on the claw sliding groove, which is beneficial to reducing the possibility of the ejection cover popping out excessively.
[0098] In combination with the first aspect, in certain implementations of the first aspect, the jaw chute includes a first chute portion and a second chute portion. The first chute portion is disposed opposite to the limiting platform. The first chute portion and the second chute portion are in through communication. The first limiting jaw can rotate around the optical axis and be drawn into the first chute portion from the second chute portion.
[0099] When assembling the pop-up cover and the camera bracket, the pop-up cover can rotate around the optical axis, so that the first limiting jaw can be drawn from the second chute portion into the first chute portion and cooperate with the limiting platform within the first chute portion. When disassembling the pop-up cover and the camera bracket, the first limiting jaw can be drawn into the second chute portion through the first chute portion, and the first limiting jaw can be unrestricted by the limiting platform within the second chute portion, so that the pop-up cover can be separated from the camera bracket.

The cover portion is fixedly connected to the pop-up pushing member, and the cover portion is fixedly connected to the lens assembly.
[0101] The pop-up driving member can drive the pop-up pushing member to drive the pop-up cover to move along the optical axis. The pop-up cover can further drive the lens to move along the optical axis. This is beneficial to enabling the mechanical protection housing and the lens of the camera module to move synchronously.
[0102] In some embodiments, a buffer member is provided on a side of the cylindrical portion facing the camera bracket.
[0103] The buffer member can buffer between the pop-up cover and the camera bracket, which is beneficial to reducing the vibration generated by the impact between the pop-up cover and the camera bracket, and further reducing the impact on the components carried on the pop-up cover and the camera bracket.

The pop-up cover is within the space formed by surrounding the bearing portion and the second protruding portion and can move along the optical axis under the drive of the pop-up pushing member. The end face of the second protruding portion away from the bearing portion is fixedly connected to the first ring body.
[0107] When the camera module is in the retracted state, the pop-up cover and part of the flexible connection member can be accommodated within the space surrounded by the camera bracket, which helps to reduce the occupied space of the camera module in the retracted state.
[0108] In some embodiments, the pop-up cover further includes an outer extension ring. The outer extension ring surrounds the outer periphery of the cylindrical portion and is located at the end of the cylindrical portion away from the cover portion. The outer extension ring is fixedly connected to the second ring body.
[0109] By providing an outer extension ring on the pop-up cover, it is beneficial to flexibly realize the connection between the pop-up cover and the flexible connection member.
[0110] In combination with the first aspect, in certain implementation manners of the first aspect, the camera module further includes a dust-proof cover plate and a dust-proof net. The dust-proof cover plate is hermetically connected to the camera bracket and the flexible connection member. A dust-proof through hole is provided on the dust-proof cover plate, and the dust-proof net covers the dust-proof through hole.
[0111] By providing a hermetic connection between the dust-proof cover plate and the camera bracket and the flexible connection member, it is beneficial to reduce the possibility of external contaminants entering the interior of the camera module. When the camera module changes from the retracted state to the pop-up state, air can enter the interior of the camera module through the dust-proof net; when the camera module changes from the pop-up state to the retracted state, air can be discharged out of the camera module through the dust-proof net. Therefore, it is beneficial to match the air pressure inside the camera module with the external air pressure during the process of the change in the internal volume of the camera module.
[0112] In some embodiments, multiple pins of the circuit board assembly can be arranged close to the dust-proof component. After the dust-proof component is disassembled from the camera module, multiple pins of the circuit board assembly can be exposed through the opening surrounded by the flexible connection member and the camera module, so that it is beneficial to perform repairs, inspections, adjustments, etc. on the pins of the circuit board assembly with a relatively small degree of disassembly of the camera module.
[0113] In combination with the first aspect, in certain implementation manners of the first aspect, the camera module further includes a circuit board, and the circuit board is disposed on the side of the camera bracket away from the lens assembly;
[0114] The circuit board includes a fourth circuit board portion and a fifth circuit board portion. The fourth circuit board portion is provided with an image sensor. The fifth circuit board portion includes a second circuit board receiving groove, and the fourth circuit board portion is received in the second circuit board receiving groove;
[0115] The fourth circuit board portion includes a first circuit board protrusion that protrudes toward the groove wall of the second circuit board receiving groove. The fifth circuit board portion includes a second circuit board protrusion that protrudes from the groove wall of the second circuit board receiving groove toward the fourth circuit board portion;
[0116] The circuit board further includes a first trace that is connected between the first circuit board protrusion and the second circuit board protrusion;
[0117] The camera module further includes an SMA wire fixing bracket, an SMA wire movable bracket, and a first SMA wire. The SMA wire fixing bracket is fixed to the fifth circuit board portion. One end of the SMA wire movable bracket is fixed to the fourth circuit board portion, and the other end of the SMA wire movable bracket is suspended above the fifth circuit board portion. The first SMA wire is connected between the SMA wire fixing bracket and the SMA wire movable bracket, and the first SMA wire is disposed opposite to a first trace portion of the first trace.
[0118] The first SMA wire can be used to realize the movement of the image sensor in a direction perpendicular to the optical axis to achieve an anti-shake function. By designing the structure of the circuit board, a first trace is formed on the circuit board opposite to the first SMA wire. When the first SMA wire shortens, the first trace can drive the image sensor to move under the drive of the first SMA wire to achieve the anti-shake function; when the first SMA wire elongates, the first trace can support the elongation of the first SMA wire through elastic recovery so that the image sensor moves toward the initial position.
[0119] In combination with the first aspect, in some implementation manners of the first aspect, a second trace portion of the first trace is disposed opposite to a second SMA wire of the camera module;
[0120] The circuit board further includes:
[0121] A second trace that is connected between the first circuit board protrusion and the second circuit board protrusion. A first trace portion of the second trace is disposed opposite to the first SMA wire, and a second trace portion of the second trace is disposed opposite to the second SMA wire;
[0122] A first linkage trace that is connected between the first trace and the second trace.
[0123] By arranging a linkage trace between two adjacent trace brackets, it is beneficial to reduce the possibility of interference between two adjacent traces.
[0124] Combined with the first aspect, in some implementation manners of the first aspect, the circuit board further includes a second linkage trace, the second linkage trace is connected between the first trace and the second trace, the first linkage trace and the second linkage trace divide a third trace portion on the first trace and the second trace, the third trace portion of the first trace is connected between the first trace portion of the first trace and the second trace portion of the first trace, the third trace portion of the second trace is connected between the first trace portion of the second trace and the second trace portion of the second trace, and the third trace portion of the first trace and the third trace portion of the second trace have different lengths.
[0125] The lengths of two adjacent traces can be different. To make the lengths of the main force - transmitting portions of the traces generally consistent, by arranging two linkage traces between two adjacent trace brackets, the partial traces between the two linkage traces can have a flexible length design to adapt to the total length of the traces.
[0126] In some embodiments, the first trace and the second trace satisfy:
[0127] The first trace portion of the first trace and the first trace portion of the second trace have the same length; and / or,
[0128] The second trace portion of the first trace and the second trace portion of the second trace have the same length.
[0129] The lengths of the main force - transmitting portions of the traces being the same is beneficial to make the force transmission of multiple traces relatively uniform and beneficial to improving the service performance of the circuit board.
[0130] In some embodiments, the fourth circuit board portion is provided with an SMA wire control module, and the SMA wire control module is electrically connected to the stator end of the first SMA wire through the first circuit board protrusion, the first trace, the second circuit board protrusion, the fifth circuit board portion, and the SMA wire fixing bracket, and the SMA wire control module is electrically connected to the rotor end of the first SMA wire through the fourth circuit board portion and the SMA wire movable bracket.
[0131] The SMA wire control module can control the elongation or shortening of the SMA wire through the circuit on the circuit board.
[0132] Combined with the first aspect, in some implementation manners of the first aspect, the camera module further includes:
[0133] A wire protection bracket is arranged on a side of the circuit board close to the camera bracket and covers the first trace.
[0134] Since the wire protection bracket covers the trace, when the SMA wire stretches and relaxes due to elastic recovery, the wire protection bracket can prevent the SMA wire from falling into the gap on both sides of the trace, thereby helping to reduce the risk of the SMA wire being pinched off by the trace.
[0135] In combination with the first aspect, in some implementations of the first aspect, the camera module further includes:
[0136] A first pre-compression pad is disposed between the fourth circuit board portion and the wire protection bracket.
[0137] A pre-press pad is provided between the fourth circuit board portion and the wire protection bracket, so that the spacing between the fourth circuit board portion and the wire protection bracket can match the size of the first pre-press pad along the optical axis. In other words, the first pre-press pad can be used to prevent the fourth circuit board portion from deforming toward the wire protection bracket. Since the image sensor can be provided on the fourth circuit board portion, providing the first pre-press pad can help reduce the displacement of the image sensor toward the wire protection bracket.
[0138] In combination with the first aspect, in some implementations of the first aspect, the third circuit board assembly further includes a reinforcing plate and a module base, the reinforcing plate and the module base are located on a side away from the camera bracket, the reinforcing plate is attached to the circuit board, and the reinforcing plate is located between the circuit board and the module base;
[0139] The camera module further includes a second pre-compression pad, which is disposed between the reinforcement plate and the module base.
[0140] A pre-press pad is provided between the fourth circuit board portion and the module base, so that the spacing between the fourth circuit board portion and the module base can match the size of the second pre-press pad along the optical axis. In other words, the second pre-press pad can be used to prevent the fourth circuit board portion from deforming toward the module base. Since the image sensor can be provided on the fourth circuit board portion, providing the second pre-press pad can help reduce the displacement of the image sensor toward the module base.
[0141] In combination with the first aspect, in some implementations of the first aspect, the camera module further includes:
[0142] A third pre-press pad is disposed between the fourth circuit board portion and the camera bracket.
[0143] A pre - pressing pad is arranged between the fourth circuit board part and the camera bracket, so that the distance between the fourth circuit board part and the camera bracket can match the dimension of the third pre - pressing pad along the optical axis. That is to say, the third pre - pressing pad can be used to prevent the fourth circuit board part from deforming towards the camera bracket. Since the image sensor can be arranged on the fourth circuit board part, setting the third pre - pressing pad can help reduce the displacement amount of the image sensor towards the camera bracket.
[0144] In a second aspect, an electronic device is provided, including the camera module described in any one of the implementation manners in the first aspect above. Description of the Drawings

[0199] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings.
[0200] For ease of understanding, the technical terms involved in the embodiments of the present application will be explained and described first.
[0201] The optical axis may refer to the direction in which an optical system conducts light, referring to the chief ray of the central field of view. For a symmetric transmission system, it generally coincides with the rotation center line of the optical system.
[0202] Auto focus (AF) may refer to using the lens imaging principle and the light reflection principle. The light reflected by the object to be photographed can form an image on the image sensor after passing through the lens; according to the object distance of the object to be photographed, by moving one or more lenses, a clear image can be formed on the image sensor. Auto focus can be simply regarded as the movement of the lens relative to the image sensor along the optical axis.
[0203] Optical image stabilization (OIS) may refer to reducing the instrument jitter phenomenon that occurs during the process of capturing optical signals by adjusting the placement angle, placement position, etc. of the lens relative to the image sensor, thereby improving the imaging quality. A possible method is to detect the displacement or angle to be compensated through, for example, a gyroscope, and then drive the lens or the image sensor to translate or rotate through a motor, so as to compensate for the image blur caused by the jitter of the imaging instrument device during the exposure period. Optical image stabilization can be simply regarded as the translation or rotation of the lens relative to the image sensor in a plane perpendicular to the optical axis.
[0204] Figure 1 shows a schematic structural diagram of an electronic device 100. The electronic device 100 may be an electronic device with a camera or photographing function, such as a mobile phone, a tablet computer, a TV (or smart screen), a laptop computer, a camera, a video recorder, a camera, etc. For ease of understanding, the embodiments of the present application will be described by taking the electronic device 100 as a mobile phone as an example.
[0205] The electronic device 100 may include a display screen 10 and a housing. The housing may include a frame and a rear cover 20. The frame may surround the outer periphery of the display screen 10, and the frame may also surround the outer periphery of the rear cover 20. There may be a certain interval between the display screen 10 and the rear cover 20. The display screen 10 may be disposed parallel to the rear cover 20.
[0206] A front camera module (CCM) 110 may be disposed on the display screen 10 of the electronic device 100. As Figure 1 shown in the left figure in, the front camera module 110 may be installed in the upper left part of the display screen 10. The front camera module 110 may be used for selfies, for example.
[0207] A rear camera module 120 may be disposed on the rear cover 20 of the electronic device 100. As Figure 1 shown in the right figure in, the rear camera module 120 may be installed in the upper middle part of the rear cover 20. The rear camera module 120 may be used for photographing the scenes around the electronic device 100, for example.
[0208] It should be understood that Figure 1 the installation positions of the front camera module 110 and the rear camera module 120 shown are merely illustrative, and this application may not limit the installation positions of the camera modules. In some other embodiments, the front camera module 110 and the rear camera module 120 may also be installed at other positions on the electronic device 100. For example, the front camera module 110 may be installed in the upper middle part or the upper right part of the display screen 10. Also, for example, the rear camera module 120 may be installed in the upper left part or the upper right part of the rear cover 20.
[0209] It should be understood that Figure 1 the installation numbers of the front camera module 110 and the rear camera module 120 shown are merely illustrative, and this application may not limit the installation numbers of the camera modules. The electronic device 100 may include a greater or smaller number of camera modules.
[0210] In Figure 2 the embodiment shown, the rear camera module 120 may be a camera module with a pop-up function (which may also be referred to as a telescopic function, a lifting function, etc.). As Figure 2 shown in the left figure in, the rear camera module 120 may be partially or completely hidden inside the electronic device. As Figure 2 shown in the right figure in, the rear camera module 120 may pop out to the outside of the electronic device. In some other embodiments, the front camera module 110 may also be a camera module with a telescopic function.
[0211] In the embodiments of the present application, the camera module has a pop-up function, which may mean that the camera module is movable relative to the entire electronic device 100, so that at least a part of the camera module can pop out of the electronic device 100 and can be hidden inside the electronic device 100.
[0212] Figure 3 It is a schematic structural diagram of a camera module 200 provided by an embodiment of the present application. Figure 4 It is an exploded view of a camera module 200 provided by an embodiment of the present application. Along Figure 3 observing the camera module 200 along the A-A cross-section shown, the cross-sectional view shown in Figure 5 can be obtained. Figure 4 The dotted line in shows the optical axis of the camera module (hereinafter simply referred to as the optical axis). The camera module 200 may include a camera bracket 210, a lens assembly 220, a pop-up assembly 230, a pop-up cover 240, and a circuit board assembly 300.
[0213] The camera bracket 210 can be used to carry multiple components inside the camera module 200. The camera bracket 210 may include a bearing portion 211 and a protruding portion 212. The protruding portion 212 may protrude from the bearing portion 211. In a possible case, the bearing portion 211 may be vertically arranged relative to the optical axis. In one embodiment, the protruding direction of the protruding portion 212 may be parallel to the optical axis. The protruding portion 212 may surround the outer periphery of the bearing portion 211. The space enclosed by the protruding portion 212 and the bearing portion 211 can be used to accommodate the lens assembly 220, the pop-up assembly 230, and the pop-up cover 240.
[0214] The lens assembly 220 may include a plurality of lenses 221 and a focusing assembly 222. The plurality of lenses 221 may be arranged along the optical axis. The optical axes of the plurality of lenses 221 may be aligned. The optical axes of the plurality of lenses 221 may be the optical axis of the camera module 200. The plurality of lenses 221 can be used to project an image onto the image sensor 310 of the circuit board assembly 300. The focusing assembly 222 can be used to move the lens 221 along the optical axis to achieve autofocus. In a possible scenario, the focusing assembly 222 may be referred to as a focusing motor.
[0215] The pop-up assembly 230 can be used to drive the pop-up cover 240 to move along the optical axis relative to the camera bracket 210. In a possible scenario, the pop-up assembly 230 may be referred to as a pop-up motor.
[0216] The pop-up cover 240 can be connected to the lens assembly 220, and the lens assembly 220 can move along the optical axis relative to the camera bracket 210 under the drive of the pop-up cover 240. The pop-up cover 240 can also be used to accommodate the lens assembly 220, so as to provide mechanical protection for the lens assembly 220.
[0217] The image sensor 310 of the circuit board assembly 300 may output the captured image information. The center of the image sensor 310 may be disposed opposite to the optical axis. In a possible case, the optical axis may pass through the center of the image sensor 310. The circuit board assembly 300 may be fixedly connected to the side of the camera bracket 210 facing away from the lens assembly 220.
[0218] The multiple lenses 221 of the lens assembly 220 may be divided into a lens group 223 and a lens group 224. The lens group 223 may include one or more lenses 221a. The lens group 224 may include one or more lenses 221b.
[0219] Figure 6 is a schematic structural diagram of a lens group 223 provided by an embodiment of the present application. Along Figure 6 the B-B cross-section shown, a cross-sectional view of the lens group 223 as shown can be obtained. In some embodiments provided by the present application, the lens group 223 may be the lens group farthest from the image sensor 310. It should be understood that Figure 7 the lens shapes, the number of lenses, etc. shown in Figure 6 and Figure 7 are merely illustrative, and the embodiments of the present application may not be limited to Figure 6 and Figure 7 the embodiments shown.
[0220] The lens group 223 may include a lens 221a1 and a lens 221a2. The lens 221a1 and the lens 221a2 may be two adjacent lenses 221a. In Figure 6 and Figure 7 the some embodiments shown, the lens 221a1 may be the lens 221a in the lens group 223 that is farthest from the image sensor 310.
[0221] As Figure 7 shown, the lens group 223 may further include a lens barrel 2231. The lens barrel 2231 may be used to house the lens 221a1 and the lens 221a2. The lens 221a2 may be fixed to the inner wall of the lens barrel 2231. The lens barrel 2231 may include a barrel wall 2232 and a barrel wall 2233. The inner diameter of the barrel wall 2232 may be the same as or approximately the same as the outer diameter of the lens 221a1. The barrel wall 2232 may be fixedly connected to the lens 221a1. The inner diameter of the barrel wall 2233 may be the same as or approximately the same as the outer diameter of the lens 221a2. The barrel wall 2233 may be fixedly connected to the lens 221a2. Combining Figure 5 and Figure 7 , the outer wall of the lens barrel 2231 may be fixedly connected to the hole wall of the lens receiving cavity 2251 of the focusing stator 225.
[0222] To facilitate the installation of the lens 221a, the inner diameter of the barrel wall 2233 can be larger than that of the barrel wall 2232. That is to say, the inner diameter of the barrel wall 2233 is not too small to block the installation of the lens 221a1. When installing the lens 221a1 and the lens 221a2, the lens 221a1 can be pushed into the lens barrel 2231 through the opening of the lens barrel 2231 close to the barrel wall 2233 and pushed to the barrel wall 2232; then, the lens 221a2 can be pushed into the lens barrel 2231 through the opening of the lens barrel 2231 close to the barrel wall 2233 and pushed to the barrel wall 2233.
[0223] The lens barrel 2231 may further include a lens bearing surface 2234, and the lens bearing surface 2234 can be connected to the side of the barrel wall 2232 away from the barrel wall 2233. The lens 221a1 can be carried on the lens bearing surface 2234. That is to say, the lens bearing surface 2234 can be used to position the lens 221a1 in the lens barrel 2231 so that the lens 221a1 can be installed at a specified position in the lens barrel 2231 relatively accurately.
[0224] The lens barrel 2231 may further include a lens bearing surface 2235, and the lens bearing surface 2235 can be connected between the barrel wall 2232 and the barrel wall 2233. The lens 221a2 can be carried on the lens bearing surface 2235. That is to say, the lens bearing surface 2235 can be used to position the lens 221a2 in the lens barrel 2231.
[0225] In Figure 7 In the illustrated embodiment, the lens group 223 may further include a lens 221a3, and the lens 221a3 can be received in the lens barrel 2231. The lens barrel 2231 may further include a barrel wall 2236 and a lens bearing surface 2237. The inner diameter of the barrel wall 2236 can be the same as or approximately the same as the outer diameter of the lens 221a3, and the inner diameter of the barrel wall 2236 can be larger than the inner diameter of the barrel wall 2233. The lens bearing surface 2237 can be connected between the barrel wall 2233 and the barrel wall 2236. The lens 221a3 can be carried on the lens bearing surface 2237 and fixedly connected to the barrel wall 2236.
[0226] Figure 8 It is a schematic structural diagram of another lens group 223 provided by an embodiment of the present application. When observing along the Figure 8 illustrated C-C section, a sectional view of the lens group 223 as shown in Fig. 9 can be obtained. It should be understood that Figure 8 and Fig. 9 the lens shapes, the number of lenses, etc. shown are only illustrative, and the embodiments of the present application may not be limited to Figure 8 and Fig. 9 the illustrated embodiments.
[0227] Compared with Figure 6 and Figure 7 is similar to the illustrated embodiment, Figure 8 and Fig. 9 the lens group 223 shown may include lenses 221a1, 221a2, 221a3 and a lens barrel 2231. The lens barrel 2231 may be used to house the lenses 221a2 and 221a3. The lenses 221a2 and 221a3 may be fixed to the inner wall of the lens barrel 2231. Different from Figure 6 and Figure 7 the illustrated embodiment, Figure 8 and Fig. 9 the lens 221a1 shown may be disposed outside the lens barrel 2231.
[0228] As Figure 8 and Fig. 9 shown, the end face 2238 of the lens barrel 2231 away from the lens 221a2 may be used to fix the lens 221a1. The lens 221a1 may include a lens body 221a4 and a lens body 221a5. The lens body 221a4 may be the effective imaging area of the lens 221a1. The lens body 221a5 may extend from the lens body 221a4 away from the optical axis. The lens body 221a5 may be located outside the effective imaging area of the lens 221a1. The side of the lens body 221a5 close to the lens 221a2 may be fixed to the end face 2238 of the lens barrel 2231 away from the lens 221a2.
[0229] In one embodiment, the lens barrel 2231 may include a lens barrel body 2239 and a lens barrel protrusion 22310. The lens barrel protrusion 22310 may protrude from the lens barrel body 2239 toward the optical axis. The lens barrel protrusion 22310 may be located at one end of the lens barrel body 2239 away from the lens group 224. The lens barrel protrusion 22310 may be clamped between the lenses 221a1 and 221a2. One side of the lens barrel protrusion 22310 may be used to carry the lens 221a1, and the other side of the lens barrel protrusion 22310 may be used to carry the lens 221a2. The dimension of the lens barrel protrusion 22310 in the direction of the optical axis may be used to position the lenses 221a1 and 221a2 so that the distance between the lenses 221a1 and 221a2 meets the shooting requirements.
[0230] In a possible case, the projection area of the lens barrel protrusion 22310 on the lens 221a1 may be located outside the effective imaging area of the lens 221a1. The projection area of the lens barrel protrusion 22310 on the lens 221a2 may be located outside the effective imaging area of the lens 221a2. That is to say, the lens barrel protrusion 22310 may not block the imaging of the lenses 221a1 and 221a2.
[0231] In Figure 6 and Figure 7In the illustrated embodiment, for ease of installation, the sizes of the lenses 221a1, 221a2, and 221a3 increase in sequence. Correspondingly, the outer peripheral size of the lens barrel 2231 is at least larger than the outer peripheral size of the largest lens 221a accommodated by the lens barrel 2231. In Figure 8 and Fig. 9 In the illustrated embodiment, the lens 221a1 can be disposed outside the lens barrel 2231. Therefore, the number of lenses 221a to be installed inside the lens barrel 2231 is relatively small, which is conducive to reducing the outer diameter of the lens barrel 2231, and further conducive to reducing the occupied space of the lens group 223 in the camera module 200.
[0232] Fig.10 FIG. is a schematic structural diagram of another lens group 223 provided by an embodiment of the present application. Along Fig.10 the D-D cross-section shown, the cross-sectional view of the lens group 223 shown in Fig.11 can be obtained. It should be understood that Fig.10 and Fig.11 the lens shapes, the number of lenses, etc. shown in Fig.10 and Fig.11 are merely illustrative, and the embodiments of the present application may not be limited to
[0233] Similar to the embodiment shown in Figure 8 and Fig. 9 the lens group 223 shown in Fig.10 and Fig.11 may include the lenses 221a1, 221a2, 221a3, and the lens barrel 2231. The lens 221a1 can be disposed outside the lens barrel 2231. The lens barrel 2231 can be used to accommodate the lenses 221a2 and 221a3.
[0234] In Fig.10 and Fig.11 In the illustrated embodiment, the lens barrel 2231 may further include a lens cover 22311. The lens cover 22311 can be disposed on the side of the lens body 221a5 of the lens 221a1 away from the lens 221a2. That is to say, the lens cover 22311 can be fixedly connected to the lens body 221a5 of the lens 221a1. The lens 221a1 can be clamped between the lens barrel 2231 and the lens cover 22311. Combining Figure 5 and Fig.11 , the outer wall of the lens cover 22311 can be fixedly connected to the hole wall of the lens accommodation cavity 2251 of the focusing stator 225.
[0235] The lens cover 22311 can be cylindrical. The lens cover 22311 can include a hollow cavity, and the lens cover 22311 can have a lens cover opening 22312 and a lens cover opening 22313 at both ends of the cavity. The lens cover opening 22312 can be the opening of the lens cover 22311 away from the lens 221a1. The lens cover opening 22313 can be the opening of the lens cover 22311 close to the lens 221a1. In some embodiments, from the lens cover opening 22312 to the lens cover opening 22313, the inner diameter of the lens cover 22311 can gradually decrease.
[0236] In some embodiments, the outer peripheral dimension of the lens cover 22311 can be substantially the same as the outer peripheral dimension of the lens barrel 2231. That is, when viewed along the optical axis, the outer contour of the projection area of the lens cover 22311 can overlap or approximately overlap with the outer contour of the projection area of the lens barrel 2231. In a possible case, the outer peripheral dimension of the lens 221a1 can be smaller than the outer peripheral dimension of the lens cover 22311 or the lens barrel 2231.
[0237] Combined Figure 5 and Fig.11 , the lens barrel 2231 and the lens cover 22311 can be fixed to the inner wall of the lens accommodation cavity 2251 of the focusing stator 225 by, for example, a colloid. Since the lens 221a1 can be clamped between the lens barrel 2231 and the lens cover 22311, the combination of the lens barrel 2231 and the lens cover 22311 can help to strengthen the fixing stability of the lens 221a1 in the lens accommodation cavity 2251 and help to prevent the lens 221a1 from falling off the lens barrel 2231. The spaced space between the lens 221a1 and the lens accommodation cavity 2251 can be used to accommodate the colloid, which helps to reduce the possibility of the colloid overflowing at the joint of the lens 221a1 and the lens cover opening 22313.
[0238] Fig.12 is a schematic structural diagram of a lens group 224 provided by an embodiment of the present application. When viewed along the Fig.12 E-E section shown, a sectional view of the lens group 224 shown in Fig.13 can be obtained. It should be understood that Fig.12 and Fig.13 shown in the shape of the lens, the number of lenses, etc. are only illustrative, and the embodiments of the present application may not be limited to Fig.12 and Fig.13 shown in the embodiments.
[0239] The lens group 224 may include lenses 221b1, 221b2, 221b3, 221b4 and a lens barrel 2241. The lens barrel 2241 may be used to house the lenses 221b1, 221b2, 221b3 and 221b4. The lenses 221b1, 221b2, 221b3 and 221b4 may be fixedly connected to the inner wall of the lens barrel 2241. Combining Figure 5 and Fig.12 , the outer peripheral dimensions of the lenses 221b1, 221b2, 221b3 and 221b4 may decrease in sequence, so that the lenses 221b1, 221b2, 221b3 and 221b4 may be installed into the lens barrel 2241 from the opening of the lens barrel 2241 away from the lens group 223.
[0240] The lens 221b1 may be carried on the lens body of the lens 221b2, the lens 221b2 may be carried on the lens body of the lens 221b3, and the lens 221b3 may be carried on the lens body of the lens 221b4. The lens barrel 2241 may include a lens barrel body 2242 and a lens barrel protrusion 2243. The lens barrel protrusion 2243 may protrude from the lens barrel body 2242 toward the optical axis. Combining Figure 5 and Fig.13 , the lens barrel protrusion 2243 may be located at one end of the lens barrel body 2242 away from the lens group 223. The lens 221b4 may be carried on the lens barrel protrusion 2243. The lens barrel protrusion 2243 may not block the imaging of the lenses 221b1, 221b2, 221b3 and 221b4.
[0241] Fig.14 and Fig.15 are the exploded views of a lens assembly 220 provided by an embodiment of the present application. Fig.14 and Fig.15 The dotted lines in show the optical axis.
[0242] The focusing assembly 222 may include a focusing stator 225 and a focusing mover 226. The focusing mover 226 may move relative to the focusing stator 225. The lens group 223 may be fixedly connected to the focusing stator 225. The lens group 224 may be fixedly connected to the focusing mover 226. When the focusing mover 226 moves along the optical axis relative to the focusing stator 225, the lens group 224 may move along the optical axis relative to the lens group 223 driven by the focusing mover 226, so that an autofocus function may be achieved.
[0243] Combining Fig.14 and Fig.15, a lens receiving cavity 2251 may be provided in the central region of the focusing stator 225. The lens group 223 may be fixed within the lens receiving cavity 2251. In one embodiment, the lens group 223 may be directly fixed to the inner wall of the lens receiving cavity 2251 by means such as pasting or snap connection. In another embodiment, the lens assembly 220 may further include a lens barrel. The lens group 223 may be assembled within the lens barrel, and the lens barrel may be fixed to the inner wall of the lens receiving cavity 2251. The lens group 224 may be received within the lens receiving cavity 2251 and located at an end of the lens receiving cavity 2251 away from the lens group 223. The lens group 224 may move along the optical axis within the lens receiving cavity 2251.
[0244] Combined with Fig.14 and Fig.15 , the focusing mover 226 may include a platform portion 2261. A light-transmitting hole 2262 may further be provided in the central region of the platform portion 2261. The light-transmitting hole 2262 may be disposed opposite to the lens group 224. The light passing through the lens group 224 may further pass through the light-transmitting hole 2262. In a possible case, the platform portion 2261 may be disposed perpendicular to the optical axis.
[0245] In one embodiment, the focusing mover 226 may further include a lens mounting ring 2263. The lens mounting ring 2263 may be disposed on a side of the platform portion 2261 close to the focusing stator 225. The cavity formed by surrounding the lens mounting ring 2263 may communicate with the light-transmitting hole 2262. The lens group 224 may be received within the cavity formed by surrounding the lens mounting ring 2263. The lens group 224 may be fixedly connected to the inner wall of the lens mounting ring 2263. By mounting the lens group 224 on the inner wall of the lens mounting ring 2263, the lens group 224 may be fixedly connected to the focusing mover 226. The lens mounting ring 2263 may be beneficial to increasing the area of the focusing mover 226 for fixing the lens group 224 and beneficial to improving the stability of the fixed connection between the lens group 224 and the focusing mover 226.
[0246] Fig.16 FIG. shows an internal structure diagram of a camera module 200 provided by an embodiment of the present application.
[0247] Continuing to combine Figures 14 to 16 , in some embodiments provided by the present application, the focusing assembly 222 may further include a focusing driving member 227 and a focusing pushing member 228. By the focusing driving member 227 and the focusing pushing member 228, the focusing mover 226 may be driven to move along the optical axis relative to the focusing stator 225. Observing a camera module 200 provided by an embodiment of the present application along the M-M cross-section shown in Fig.16 , a cross-sectional view as shown in Fig.17 can be obtained.
[0248] The focusing driving member 227 can be carried on the focusing stator 225. The focusing driving member 227 can be used to drive the focusing pushing member 228 to move along the optical axis. The focusing pushing member 228 can be fixedly connected to the focusing mover 226. Therefore, the focusing mover 226 can move along the optical axis under the drive of the focusing pushing member 228. Thus, the focusing mover 226 can move relative to the focusing stator 225 along the optical axis.
[0249] Combined Figure 5 、 Figures 14 to 16 , in some embodiments provided by the present application, the focusing mover 226 can be located between the focusing stator 225 and the camera bracket 210. The focusing driving member 227 and the focusing pushing member 228 can be used to drive the focusing mover 226 to move along the optical axis between the focusing stator 225 and the camera bracket 210. In other embodiments provided by the present application, the focusing mover 226 can be located on the side of the focusing stator 225 away from the camera bracket 210. The focusing driving member 227 and the focusing pushing member 228 can be used to drive the focusing mover 226 to move along the optical axis on the side of the focusing stator 225 away from the camera bracket 210. The present application takes Figure 5 、 Figures 14 to 16 The illustrated embodiments are described as examples. Other embodiments can refer to Figure 5 、 Figures 14 to 16 The illustrated embodiments.
[0250] In the embodiments provided by the present application, the driving of the focusing driving member 227 on the focusing pushing member 228 can be achieved through mechanical transmission principles (such as stepping motors), electromagnetic principles (such as Hall magnets), piezoelectric principles (such as piezoelectric ceramics), etc.
[0251] Next, combined with Figures 14 to 17 , a focusing mode provided by the embodiments of the present application is described.
[0252] On the side of the focusing stator 225 facing the focusing mover 226, a step 2254 can be provided. The step 2254 can be located in the edge area of the focusing stator 225 and on the side of the focusing stator 225 close to the focusing mover 226. That is to say, the step 2254 can be located in the area outside the lens accommodation cavity 2251. As Fig.16 And 17 Shown, a focusing driving accommodation hole 2255 can be provided on the step 2254. The focusing driving accommodation hole 2255 can extend along the optical axis. The focusing driving accommodation hole 2255 can be used to accommodate the focusing driving member 227. The focusing driving member 227 can reciprocate along the optical axis in the focusing driving accommodation hole 2255.
[0253] As Fig.17As shown, the focusing driving member 227 may include a focusing pusher accommodating hole 2271 and a focusing pusher accommodating hole 2272. The focusing pusher accommodating hole 2271 and the focusing pusher accommodating hole 2272 communicate with each other. The axis of the focusing pusher accommodating hole 2272 may be aligned with the axis of the focusing pusher accommodating hole 2272. The focusing pusher accommodating hole 2271 is located at one end of the focusing driving member 231 close to the focusing mover 226. The focusing pusher accommodating hole 2272 is located at one end of the focusing driving member 231 away from the focusing mover 226. The inner diameter of the focusing pusher accommodating hole 2271 may be smaller than that of the focusing pusher accommodating hole 2272. In a possible case, the focusing driving member 227 may have a piezoelectric ceramic. The focusing pusher accommodating hole 2272 may be provided on the piezoelectric ceramic.
[0254] The focusing pusher 228 may be disposed in the focusing pusher accommodating hole 2271 and the focusing pusher accommodating hole 2272. The focusing pusher 228, the focusing pusher accommodating hole 2271 and the focusing pusher accommodating hole 2272 may extend along the optical axis. One end of the focusing pusher 228 may extend out of the focusing pusher accommodating hole 2271 and be fixed to the platform portion 2261 of the focusing mover 226. As Fig.14 , Fig.15 and Fig.17 shown, a fixing ring 2269 may be provided on the platform portion 2261, and the focusing pusher 228 may be fixed in the fixing ring 2269.
[0255] The focusing pusher 228 may be formed by bending a sheet. As Fig.16 shown, the focusing pusher 228 may be a tubular structure having a slit 2281. In a possible case, the slit 2281 of the focusing pusher 228 may be arranged parallel to the optical axis. When the focusing pusher 228 is not placed in the focusing pusher accommodating hole 2271 of the focusing driving member 227, the slit 2281 of the focusing pusher 228 may be relatively large. After the focusing pusher 228 is placed in the focusing pusher accommodating hole 2271 of the focusing driving member 227, the focusing pusher 228 is squeezed by the hole wall of the focusing pusher accommodating hole 2271, so that the slit 2281 of the focusing pusher 228 can be narrowed. Thus, the outer periphery of the focusing pusher 228 may press against the hole wall of the focusing pusher accommodating hole 2271, so that there may be a frictional force between the focusing pusher 228 and the focusing pusher accommodating hole 2271. When the focusing driving member 227 is not working, there may be a static frictional force between the focusing pusher 228 and the focusing pusher accommodating hole 2271, and this static frictional force may keep the focusing pusher 228 relatively stationary in the focusing pusher accommodating hole 2271. This is beneficial to make the focusing mover 226 hover relative to the focusing stator 225.
[0256] The focusing driving member 227 can conduct a focusing resonance signal. At the same moment, the displacement of one end of the focusing driving member 227 close to the circuit board assembly 300 can be in the opposite direction to the displacement of the other end of the focusing driving member 227 away from the circuit board assembly 300. For example, at the same moment, one end of the focusing driving member 227 close to the circuit board assembly 300 moves towards the circuit board assembly 300, and the other end of the focusing driving member 227 away from the circuit board assembly 300 moves towards the ejecting cover 240. That is to say, the focusing driving member 227 can be in an extended state. Another example is that at the same moment, one end of the focusing driving member 227 close to the circuit board assembly 300 moves towards the ejecting cover 240, and the other end of the focusing driving member 227 away from the circuit board assembly 300 moves towards the circuit board assembly 300. That is to say, the focusing driving member 227 can be in a contracted state. The focusing driving member 227 can periodically switch between the extended state and the contracted state.
[0257] During the process of the focusing pushing member 228 moving towards the circuit board assembly 300, the time when the focusing driving member 227 is in the extended state can be longer than the time when the focusing driving member 227 is in the contracted state. That is to say, the extension speed of the focusing driving member 227 is relatively slow, and the contraction speed of the focusing driving member 227 is relatively fast.
[0258] Within one cycle, when the focusing driving member 227 slowly extends, due to the frictional force between the focusing pushing member 228 and the focusing pushing member receiving hole 2271, the focusing pushing member 228 can be driven by the focusing driving member 227 to move towards the circuit board assembly 300. The displacement amount of the focusing pushing member 228 moving towards the circuit board assembly 300 can be the same as or close to 50% of the extension amount of the focusing driving member 227. When the focusing driving member 227 quickly contracts, due to inertia, the displacement amount of the focusing pushing member 228 moving away from the circuit board assembly 300 is less than 50% of the contraction amount of the focusing driving member 227. Since the extension amount and the contraction amount of the focusing driving member 227 are the same within one cycle, therefore, within one cycle, the displacement amount of the focusing pushing member 228 moving towards the circuit board assembly 300 can be greater than the displacement amount of the focusing pushing member 228 moving away from the circuit board assembly 300. The focusing driving member 227 can repeatedly expand and contract in multiple cycles, so that the focusing pushing member 228 can be gradually moved out of the focusing pushing member receiving hole 2272 towards the circuit board assembly 300.
[0259] The principle of the focusing pushing member 228 gradually moving back into the focusing pushing member receiving hole 2272 can refer to the embodiment in which the focusing pushing member 228 gradually moves out of the focusing pushing member receiving hole 2272.
[0260] As described above, at the same moment, the moving directions of the two ends of the focus drive 227 are opposite, so the focus drive 227 can have a focus resonance zero point, and the displacement of the focus drive 227 at the focus resonance zero point can be regarded as zero. The position of the focus drive 227 near the resonance zero point can be connected to the step 2254 of the focus mover 225. The step 2254 can be arranged relative to the position of the focus drive 227 near the resonance zero point. In a possible case, the position of the focus drive 227 near the resonance zero point can have a mounting ear (not shown in the figure), and the focus drive 227 can be connected to the step 2254 of the focus mover 225 through the mounting ear.
[0261] When the focus driver 227 is working, the focus driver 227 may vibrate back and forth slightly along the optical axis. The focus driver 227 can be connected to the step 2254 of the focus mover 225 through an elastic connector, which can be, for example, foam, silicone, etc. The elastic connector can absorb the tiny vibration of the focus driver 227, which is conducive to improving the connection stability between the focus driver 227 and the focus mover 225.
[0262] In other embodiments provided in the present application, the focus mover 226 can be driven by a stepper motor to move relative to the focus stator 225. However, the stepper motor and related variable speed transmission components occupy a relatively large space. In addition, the stepper motor can rotate the lens to achieve the movement of the lens along the optical axis. In the process of the stepper motor rotating the lens, the displacement of the lens from the optical axis is difficult to control. The camera module usually has a large number of lenses, so it is relatively difficult to align the centers of multiple lenses during the focusing process, which affects the imaging effect. The stepper motor is also prone to introduce noise, affecting the quality of video shooting. The focus assembly provided in the present application can apply the piezoelectric principle, the focus assembly occupies relatively less space, and the focus mover 226 can move in a straight line along the optical axis, which is conducive to reducing the displacement of the focus mover 226 from the optical axis, and the noise caused by the focus assembly is relatively less.
[0263] In other embodiments provided in the present application, the focus mover 226 can be driven by a Hall magnet to move relative to the focus stator 225. However, when the space occupied by the Hall magnet is reasonable, the stroke that the Hall magnet can achieve is relatively short. In the embodiment provided in the present application, since the focus stator 225 can be ejected, the movable stroke of the focus stator 226 is relatively large. In order to meet the stroke requirements, multiple Hall magnets can be arranged in the camera module 200. However, multiple Hall magnets may interfere with each other. Driven by the Hall magnet, a self-locking module needs to be additionally arranged. The focusing assembly provided in the present application can apply the piezoelectric principle, and can achieve a relatively long focusing stroke in a relatively small space, which is conducive to taking into account requirements such as stroke and occupied space.
[0264] Continuing with the combination Figures 14 to 17 , in some embodiments provided by the present application, the focusing stator 225 may further include a focusing through hole 2258. The lens assembly 220 may further include a focusing guide rod 410. The focusing guide rod 410 may be fixed to the platform portion 2261 of the focusing mover 226 and received in the focusing through hole 2258. As Fig.15 and 17 shown, a fixing ring 22610 may be provided on the platform portion 2261, and the focusing guide rod 410 may be fixed within the fixing ring 22610. The focusing through hole 2258 and the focusing guide rod 410 may extend along the optical axis. The projection area of the focusing guide rod 410 on the platform portion 2261 of the focusing mover 226 may be located outside the light-transmitting hole 2262 of the platform portion 2261. The focusing guide rod 410 and the focusing guide hole 2258 cooperate with each other. When the focusing mover 226 moves along the optical axis relative to the focusing stator 225, the focusing mover 226 may drive the focusing guide rod 410 to move along the optical axis. The focusing through hole 2258 may be used to guide the focusing guide rod 410, which is beneficial to reducing the displacement amount of the focusing mover 226 deviating from the optical axis. In a possible case, the focusing guide rod 410 and the focusing driving member 227 may be symmetrically arranged with respect to the plane where the optical axis is located.
[0265] In a possible case, the azimuth angles of the focusing guide rod 410 and the focusing driving member 227 with respect to the optical axis are 45° to 135°. That is, when projected along the optical axis direction, the connection line between the center of the projection area of the focusing guide rod 410 and the optical axis is connection line e, and the connection line between the center of the projection area of the focusing driving member 227 and the optical axis is connection line f, and the angle between connection line e and connection line f is 45° to 135°. The focusing guide rod 410 and the focusing driving member 227 can guide the focusing mover 226 from different azimuths, which is beneficial to reducing the displacement amount of the focusing mover 226 deviating from the optical axis.
[0266] Continuing with the combination Fig.14 and Fig.15 , in some embodiments provided by the present application, a circuit board assembly 229 may be fixed on the focusing stator 225. Fig.18 Shows the assembly relationship between the circuit board assembly 229 and the focusing stator 225. Fig.19 Shows the assembly relationship between the circuit board assembly 229 and the focusing mover 226. Fig. 20 Is a schematic structural diagram of a circuit board assembly 229 provided by an embodiment of the present application. Looking at the camera module 200 along the Fig.19 shown F-F cross-section, the cross-sectional view shown in Fig.21 can be obtained.
[0267] The circuit board assembly 229 may include a circuit board portion 229a, a circuit board portion 229b, and a circuit board portion 229c. The circuit board portion 229a may be connected between the circuit board portion 229b and the circuit board portion 229c.
[0268] The circuit board portion 229a may include a component area 2294 (as Fig. 20 indicated by the short dashed line therein) and a fixing area 2295 (as Fig. 20 indicated by the long dashed line therein). In one embodiment, the circuit board portion 229a may be a rigid board. It should be understood that Fig. 20 the shown component area 2294 and fixing area 2295 are only for illustration and explanation purposes, and the embodiments of the present application may not be limited to Fig. 20 the specific examples shown.
[0269] The component area 2294 and the fixing area 2295 may be located on the same side of the circuit board portion 229a, and the component area 2294 and the fixing area 2295 may not cross each other.
[0270] The component area 2294 may be used to set components. In combination with Fig.18 and Fig. 20 , the focusing stator 225 may further include a component receiving groove 2256, and the component receiving groove 2256 may be disposed opposite to the component area 2294 of the circuit board portion 229a. That is to say, the component area 2294 may be located within the projection area of the component receiving groove 2256 on the circuit board portion 229a. The space enclosed by the component receiving groove 2256 and the circuit board portion 229a may be used to accommodate the components on the component area 2294.
[0271] In combination with Fig.18 and Fig. 20 , the fixing area 2295 may be used to fixedly connect with the side wall of the focusing stator 225. In one possible case, the side wall of the focusing stator 225 may be a wall parallel to the optical axis.
[0272] The focusing stator 225 may further have a circuit board receiving groove 2257. The circuit board receiving groove 2257 may be recessed from the side wall of the focusing stator 225 toward the optical axis. The circuit board receiving groove 2257 may have a groove wall 22571 and a groove wall 22572, and the groove wall 22571 and the groove wall 22572 may be disposed opposite to each other. The circuit board portion 229b of the circuit board assembly 229 may be clamped between the groove wall 22571 and the groove wall 22572. The distance between the groove wall 22571 and the groove wall 22572 may be greater than or equal to the thickness of the circuit board portion 229b. The circuit board portion 229b may be fixedly connected with the groove wall 22571 and / or the groove wall 22572. In one embodiment, the circuit board portion 229b may be a flexible board.
[0273] Combined with Fig.14 , Fig.15 , Fig.18 and Fig. 20 , the circuit board part 229a can be provided with a focus control module 2291. The focus control module 2291 can be used to conduct alternating current for the focus driving member 227. The circuit board part 229b can extend from the circuit board part 229a to the focus driving accommodation hole 2255 of the focus stator 225 and be electrically connected to the focus driving member 227 in the focus driving accommodation hole 2255, so that the focus control module 2291 can be electrically connected to the focus driving member 227 through the circuit board part 229a and the circuit board part 229b.
[0274] In one embodiment, the circuit board part 229b can be connected to the focus driving member 227 in the focus driving accommodation hole 2255 (for example, by welding, pasting conductive glue, etc.). A pin b1 can be provided in the area where the circuit board part 229b is connected to the focus driving member 227, and the pin b1 can be electrically connected to the focus driving member 227. In another embodiment, a pin b1 can be provided on the side of the circuit board part 229b close to the focus driving member 227, and the pin b1 can be electrically connected to the focus driving member 227 through a lead wire.
[0275] Combined with Fig.14 , Fig.15 , Fig.19 and Fig. 20 , in some embodiments provided by the present application, the focus mover 226 can be provided with a magnetic grating 2265, and a magnetoresistance 2292 can also be provided on the circuit board assembly 229. The magnetic grating 2265 and the magnetoresistance 2292 can be arranged opposite to each other, and the distance between the magnetic grating 2265 and the magnetoresistance 2292 can be relatively small. The magnetoresistance 2292 can be used to detect the distance between the magnetoresistance 2292 and the magnetic grating 2265. The magnetoresistance 2292 can be, for example, a tunnel magnetoresistance 2292 (TMR). Through the signal output by the magnetoresistance 2292, the moving displacement of the magnetic grating 2265 relative to the magnetoresistance 2292 can be obtained, so that the electrical signal conducted by the focus control module 2291 can be adjusted in a timely manner, where the electrical signal can be, for example, current and / or voltage.
[0276] In some embodiments, the focusing mover 226 may further include an extension bar 2264. The extension bar 2264 is disposed at the edge position of the platform portion 2261, and the extension bar 2264 may extend along the optical axis from the platform portion 2261. A magnetic grating 2265 may be fixed on the extension bar 2264. In one embodiment, the magnetic grating 2265 may be pasted on the extension bar 2264 by a colloid. In another embodiment, a claw 2266 may be further provided on the extension bar 2264. The magnetic grating 2265 is snapped into the claw 2266 so that the magnetic grating 2265 can be fixed to the extension bar 2264.
[0277] Combined with Fig.15 、 Fig.18 and Fig. 20 , the circuit board portion 229c can extend from the circuit board portion 229a toward the camera bracket 210. Since the lens assembly 220 can move relative to the camera bracket 210 along the optical axis, when the lens assembly 220 is located at a position relatively close to the camera bracket 210, the circuit board portion 229c can be in a folded state. When the lens assembly 220 is located at a position relatively far from the camera bracket 210, the circuit board portion 229c can be in an unfolded state. In one embodiment, the foldable portion of the circuit board portion 229c may be a flexible board.
[0278] Continuing to combine Figure 4 、 Figure 5 and Fig.18 , in some embodiments provided in the present application, a circuit board assembly 270 may be provided on the bearing portion 211 of the camera bracket 210. The circuit board assembly 270 and the circuit board assembly 300 may be located on both sides of the camera bracket 210 respectively.
[0279] Pins 301 may be provided on the circuit board assembly 300, and pins 273 may be provided on the circuit board assembly 270b. The pins 301 on the circuit board assembly 300 and the pins 273 on the circuit board assembly 270b may be disposed close to each other so that the pins 301 and the pins 273 can be electrically connected. The pins 301 and the pins 273 are electrically connected by, for example, solder balls, leads, etc. Pins 274 may be provided on the circuit board assembly 270a, and pins 2293 may be provided on the circuit board assembly 229c. The pins 274 on the circuit board assembly 270a and the pins 2293 on the circuit board assembly 229c may be disposed close to each other so that the pins 274 and the pins 2293c can be electrically connected.
[0280] Pins 302 may also be provided on the circuit board assembly 300 (see specifically Fig.31)。Pin 302 can be the communication port between the camera module 200 and the electronic device. Signals from pin 302 (such as power supply signals) can be transmitted through pin 301 of the circuit board assembly 300 to pin 273 of the circuit board assembly 270, thereby enabling communication with the components on the circuit board assembly 270. The circuit board assembly 270 can also transmit signals to pin 2293 of the circuit board assembly 229 through pin 274, thereby enabling communication with the components on the circuit board assembly 229.
[0281] Continuing to combine Fig.14 and Fig.15 , in some embodiments provided by the present application, the lens assembly 220 may further include a focus limiting member 420. The focus limiting member 420 can be fixedly connected to the focus mover 226. The focus limiting member 420 can also cooperate with the focus stator 225. When the focus mover 226 moves relative to the focus stator 225, the focus limiting member 420 can move relative to the focus stator 225 under the drive of the focus mover 226, and the focus limiting member 420 and the focus stator 225 can always have a cooperative relationship. Therefore, under the limiting action of the focus limiting member 420, the displacement amount of the focus mover 226 deviating from the optical axis can be reduced.
[0282] As Fig.19 shown, the focus limiting member 420 can be annular. The focus limiting member 420 can surround the outer periphery of the focus stator 225. The inner ring surface of the focus limiting member 420 can match the outer peripheral surface of the focus stator 225. In a possible scenario, the matching of the inner ring surface of the focus limiting member 420 and the outer peripheral surface of the focus stator 225 can mean, for example, that the inner ring surface of the focus limiting member 420 can be obtained by offsetting the outer peripheral surface of the focus stator 225 outward by a distance a, where the distance a can be the (average) spacing between the focus limiting member 420 and the focus stator 225.
[0283] In some embodiments, the focus mover 226 may further include one or more extension bars 2268. The extension bars 2268 can be disposed at the edge positions of the platform portion 2261 of the focus mover 226. The extension bars 2268 can extend along the optical axis from the platform portion 2261. The extension bars 2268 can be fixedly connected to the outer or inner periphery of the focus limiting member 420.
[0284] As described above, the focus mover 226 can move along the optical axis relative to the focus stator 225. Since the extension bars 2268 of the focus mover 226 are fixedly connected to the focus limiting member 420, the focus limiting member 420 can move relative to the focus stator 225 under the drive of the focus mover 226. The ring formed by the focus limiting member 420 can be a moving chute for the focus limiting member 420 relative to the focus stator 225. Thus, the focus limiting member 420 can be beneficial for limiting the displacement amount of the focus mover 226 deviating from the optical axis.
[0285] The circuit board portions 229a and 229b of the circuit board assembly 229 can be fixed to the focusing stator 225. As Fig.19 shown, the focusing limit member 420 can surround the outer perimeters of the circuit board portions 229a and 229b. That is to say, the circuit board portions 229a and 229b can be located within the cavity formed by the surrounding of the focusing limit member 420. The circuit board portion 229c of the circuit board assembly 229 can extend from the circuit board portion 229a to outside the focusing limit member 420. Combining Figures 19 to 21 , when the focusing limit member 420 is away from the ejection cover 240, the circuit board portion 229c can be folded outside the focusing limit member 420. When the focusing limit member 420 is close to the ejection cover 240, the circuit board portion 229c can be unfolded outside the focusing limit member 420.
[0286] Continuing to combine Fig.18 , in some embodiments provided by the present application, a limiting groove 22510 can further be provided on the side wall of the focusing stator 225, and the extending direction of the limiting groove 22510 can be parallel to the optical axis. The limiting groove 22510 can have a limiting surface 22511. The limiting surface 22511 can be located on the side of the limiting groove 22510 away from the ejection cover 240. In a possible case, the limiting surface 22511 can be arranged perpendicular to the optical axis.
[0287] Combined with FIG. Fig.19 , the focusing limit member 420 can further include a limiting claw 421. The limiting claw 421 can extend into Fig.18 the limiting groove 22510 as shown. The limiting claw 421 can be arranged, for example, on the side of the focusing limit member 420 close to the ejection cover 240. In a possible case, the limiting claw 421 can be arranged perpendicular to the optical axis.
[0288] When the focusing mover 226 approaches the focusing stator 225, the limiting claw 421 can be located at one end of the limiting groove 22510 away from the limiting surface 22511. When the focusing mover 226 moves along the optical axis away from the focusing stator 225, the limiting claw 421 can move towards the limiting surface 22511 within the limiting groove 22510. When the distance between the focusing mover 226 and the focusing stator 225 is relatively far, the limiting claw 421 can directly or indirectly abut against the limiting surface 22511. The limiting surface 22511 can limit the movement of the limiting claw 421 away from the focusing stator 225. By providing the limiting groove 22510 and the limiting claw 421, it can be beneficial to reduce the possibility that the focusing mover 226 excessively detaches from the focusing stator 225.
[0289] In a possible case, combined with Fig.14 、 Fig.15And Fig.18 A buffer member 422 may be provided on the limiting surface 22511. The buffer member 422 can be used to provide buffering between the limiting surface 22511 and the limiting claw 421.
[0290] Continuing to combine Figure 5 、 Fig.14 And Fig.15 In some embodiments provided by the present application, a buffer member 416 may also be provided on the platform portion 2261 of the focusing mover 226. The buffer member 416 may be located on the side of the platform portion 2261 facing the focusing stator 225. When the focusing mover 226 approaches the focusing stator 225, the buffer member 416 may contact the focusing stator 225. The buffer member 416 can be used to reduce the vibration generated by the impact between the focusing mover 226 and the focusing stator 225.
[0291] In a possible case, a light-transmitting hole 4161 may be provided in the central region of the buffer member 416. The light-transmitting hole 4161 may surround the outer periphery of the lens mounting ring 2263 of the focusing mover 226. Alternatively, the light-transmitting hole 4161 may communicate with the light-transmitting hole 2262 of the platform portion 2261. The aperture of the light-transmitting hole 4161 may be larger than the aperture of the light-transmitting hole 2262, which is beneficial to reducing the possibility of light acting on the buffer member 416, and further beneficial to reducing the possibility of light spots appearing in the image.
[0292] Continuing to combine Figure 5 、 Fig.14 And Fig.15 In some embodiments provided by the present application, a buffer member 417 may also be provided on the platform portion 2261 of the focusing mover 226. The buffer member 417 may be located on the side of the platform portion 2261 facing away from the focusing stator 225. When the distance between the focusing mover 226 and the focusing stator 225 is relatively far, the buffer member 417 may contact the camera bracket 210 or the circuit board assembly 270. The buffer member 417 can be used to reduce the vibration generated by the impact between the focusing mover 226 and the camera bracket 210 or the circuit board assembly 270.
[0293] In a possible case, a light-transmitting hole 4171 may be provided in the central region of the buffer member 417. The light-transmitting hole 4171 may communicate with the light-transmitting hole 2262 of the platform portion 2261. The aperture of the light-transmitting hole 4171 may be larger than the aperture of the light-transmitting hole 2262, which is beneficial to reducing the possibility of light acting on the buffer member 417, and further beneficial to reducing the possibility of light spots appearing in the image.
[0294] Fig. 22 FIG. is a schematic structural diagram of a focusing stator 225 provided by an embodiment of the present application. Looking at the camera module 200 along the F-F cross-section in Fig. 22 , the following can be obtained Fig.21 The cross-sectional view shown.
[0295] Continue to combine Fig.14 , Fig.15 , Fig.18 , Fig.19 Fig.21 and Fig. 22 , in some embodiments provided by the present application, the focusing stator 225 may include a guiding groove 2259, and the guiding groove 2259 may extend along the optical axis. The focusing mover 226 may further include an extending strip 2267. The extending strip 2267 may be disposed on the platform portion 2261 of the focusing mover 226. The extending strip 2267 may extend along the optical axis from the platform portion 2261. The extending strip 2267 may extend into the guiding groove 2259 of the focusing stator 225 and cooperate with the guiding groove 2259. When the focusing mover 226 moves relative to the focusing stator 225, the extending strip 2267 of the focusing mover 226 may move along the optical axis within the guiding groove 2259 of the focusing stator 225, thereby providing an optical axis guiding for the focusing mover 226. In a possible case, the extending strip 2267 and the extending strip 2264 may be symmetrically disposed with respect to the plane where the optical axis is located.
[0296] In some embodiments, the focusing stator 225 may further include a magnet receiving groove 22591. The magnet receiving groove 22591 may communicate with the guiding groove 2259. The magnet receiving groove 22591 may be used to accommodate the fixed magnet 22592. The magnet receiving groove 22591 may be located, for example, on the side of the focusing stator 225 close to the focusing mover 226. A moving magnet 22671 may also be disposed on the extending strip 2267 of the focusing mover 226. The distance between the fixed magnet 22592 and the moving magnet 22671 may be relatively small so that there is a magnetic force meeting the requirements between the fixed magnet 22592 and the moving magnet 22671.
[0297] The moving magnet 22671 and the fixed magnet 22592 may attract or repel each other. As Fig.21 and Fig. 22 shown, the guiding groove 2259 of the focusing stator 225 includes oppositely disposed guiding groove walls 22593 and 22594. The extending strip 2267 of the focusing mover 226 may be clamped between the guiding groove walls 22593 and 22594, wherein the guiding groove wall 22593 and the fixed magnet 22592 are on the same side of the extending strip 2267, and the guiding groove wall 22594 and the fixed magnet 22592 are on both sides of the extending strip 2267.
[0298] Assume that the moving magnet 22671 and the stationary magnet 22592 can attract each other. Under the attraction of the moving magnet 22671 and the stationary magnet 22592, the distance between the extension strip 2267 and the guide groove wall 22593 can be smaller than the distance between the extension strip 2267 and the guide groove wall 22594. That is to say, the extension strip 2267 can be relatively closer to the guide groove wall 22593 and relatively farther from the guide groove wall 22594 within the guide groove 2259.
[0299] Therefore, due to the interaction between the moving magnet 22671 and the stationary magnet 22592, when the extension strip 2267 moves within the guide groove 2259, the extension strip 2267 can always be biased towards one side of the guide groove 2259, which is conducive to reducing the displacement of the extension strip 2267 deviating from the optical axis. Also, since a plurality of lenses 221b are provided on the focusing mover 226, the plurality of lenses 221b can always be biased towards one side of the focusing stator 225, and the displacement of the plurality of lenses 221b deviating from the optical axis can be relatively small.
[0300] Combined with Fig.15 and Fig. 22 , in some embodiments provided by the present application, the focusing stator 225 may further include a magnet receiving groove 22596. The magnet receiving groove 22596 can be used to receive the guide magnet 411. The magnet receiving groove 22596 can be provided on the side wall of the focusing stator 225. Observing the camera module 200 along the G-G cross-section in Fig. 22 , a cross-sectional view as shown in Fig.23 can be obtained. Fig.24 is a schematic structural diagram of a camera bracket 210 provided by an embodiment of the present application.
[0301] As Fig.23 shown, a guide magnet 413 can be provided at a position of the camera bracket 210 facing the guide magnet 411. That is to say, the guide magnet 411 and the guide magnet 413 can be oppositely arranged. The distance between the guide magnet 411 and the guide magnet 413 can be relatively small so that there is a magnetic force meeting the requirements between the guide magnet 411 and the guide magnet 413.
[0302] In one embodiment, the magnet receiving groove 22596 can be provided, for example, on the side of the focusing stator 225 close to the focusing mover 226.
[0303] As Fig.23 and Fig.24 shown, the camera bracket 210 may further include a protrusion 213. The protrusion 213 can extend from the bearing portion 211 towards the focusing stator 225. The protruding direction of the protrusion 213 can be parallel to the optical axis. The protrusion 213 can be oppositely arranged with the guide magnet 411. One side of the protrusion 213 facing the focusing stator 225 can be used to provide the guide magnet 413.
[0304] The guiding magnet 413 and the guiding magnet 411 can attract or repel each other. Due to the acting force between the guiding magnet 413 and the guiding magnet 411, the focusing stator 225 can move relatively closer to or farther away from the protrusion 213. Therefore, when the focusing stator 225 moves along the optical axis driven by the ejection cover 240, the focusing stator 225 can always deviate to one side of the camera bracket 210, which is beneficial to reducing the displacement amount of the focusing stator 225 deviating from the optical axis. Also, since a plurality of lenses 221a are provided on the focusing stator 225, the plurality of lenses 221a can always deviate to one side of the camera bracket 210, and the displacement amount of the plurality of lenses 221a deviating from the optical axis can be relatively small.
[0305] In a possible case, the azimuth angles of the guiding magnet 411 and the fixed magnet 22592 with respect to the optical axis are 0° to 15° or 165° to 180°. That is, projected along the optical axis direction, the connecting line between the center of the projection area of the guiding magnet 411 and the optical axis is the connecting line g, and the connecting line between the center of the projection area of the fixed magnet 22592 and the optical axis is the connecting line h, and the angle between the connecting line g and the connecting line h is 0° to 15° or 165° to 180°. The guiding magnet 411 and the fixed magnet 22592 can act jointly so that the plurality of lenses on the focusing stator 225 and the plurality of lenses on the focusing mover 226 can deviate to the same side of the camera module, which is beneficial to aligning the centers of the plurality of lenses on the focusing stator 225 and the centers of the plurality of lenses on the focusing mover 226.
[0306] Continuing to combine Fig.14 、 Fig.15 and Fig. 22 , in some embodiments provided by the present application, the focusing stator 225 can be provided with a positioning magnet 414 and a positioning magnet 415 (the positioning magnet can be, for example, a Hall magnet). The positioning magnet 414 can be disposed in the magnet receiving groove 22595 of the focusing stator 225. The positioning magnet 415 can be disposed in the magnet receiving groove 22597 of the focusing stator 225. Observing the camera module 200 along the H-H cross-section shown in Fig. 22 , the cross-sectional views shown in Fig.25 and Fig.26 can be obtained.
[0307] In one embodiment, the positioning magnet 414 and the positioning magnet 415 can be arranged along the optical axis. That is, projected along the optical axis, the projection area of the positioning magnet 414 can at least cross the projection area of the positioning magnet 415. The positioning magnet 414 can be located on the side of the focusing stator 225 close to the ejection cover 240. The positioning magnet 415 can be located on the side of the focusing stator 225 close to the camera bracket 210. The distance between the positioning magnet 414 and the positioning magnet 415 along the optical axis can be the same as the ejection distance of the focusing stator 225.
[0308] Continue to combine Fig.18 、 Fig.25 and Fig.26 In some embodiments provided by the present application, the circuit board assembly 270 may include a circuit board portion 271 and a circuit board portion 272. The circuit board portion 271 may be disposed on the bearing portion 211 of the camera bracket 210. The circuit board portion 272 may extend from the circuit board portion 271 toward the ejecting cover 240. As Fig.18 shown, the circuit board portion 272 may be located on one side of the focusing stator 225. In a possible case, the circuit board portion 272 may be disposed perpendicular to the circuit board portion 271. In one embodiment, the circuit board portion 271 may be a rigid board, a flexible board, or a rigid-flex board, and the circuit board portion 272 may be a rigid board, a flexible board, or a rigid-flex board.
[0309] In some embodiments, as Figure 24 to Figure 26 shown, the camera bracket 210 may include a protruding portion 214. The protruding portion 214 may protrude from the bearing portion 211, and the protruding direction of the protruding portion 214 may be parallel to the optical axis. The circuit board portion 272 may be attached to the protruding portion 214. The camera bracket 210 supports the circuit board portion 272 through the protruding portion 214, which may help reduce the possibility of the circuit board portion 272 tilting. If the circuit board portion 272 tilts, the components on the circuit board portion 272 may be displaced. The camera bracket 210 supports the circuit board portion 272 through the protruding portion 214, which may also help improve the connection stability between the circuit board portion 271 and the circuit board portion 272.
[0310] A displacement sensor 2721 (the displacement sensor 2721 may be, for example, a Hall displacement sensor) may be disposed on the circuit board portion 272. The displacement sensor 2721 may be disposed on the circuit board portion 272, for example, by surface mounted technology (SMT).
[0311] As Fig.25 shown, when the focusing stator 225 approaches the camera bracket 210, that is, when the camera module 200 is in a contracted state, the distance between the positioning magnet 414 and the displacement sensor 2721 is relatively small, so that the positioning magnet 414 can be located within the effective detection range of the displacement sensor 2721. The positioning magnet 414 may be disposed opposite to the displacement sensor 2721. The positioning magnet 415 may be outside the effective detection range of the displacement sensor 2721. That is, the magnetic field generated by the positioning magnet 415 has a relatively small influence on the displacement sensor 2721.
[0312] As Fig.26As shown, when the focusing stator 225 is far from the camera bracket 210, that is, when the camera module 200 is in the ejected state, the distance between the positioning magnet 415 and the displacement sensor 2721 is relatively small, so that the positioning magnet 415 can be located within the effective detection range of the displacement sensor 2721. The positioning magnet 415 can be disposed opposite to the displacement sensor 2721. The positioning magnet 414 can be outside the effective detection range of the displacement sensor 2721. That is to say, the influence of the magnetic field generated by the positioning magnet 414 on the displacement sensor 2721 is relatively small.
[0313] The positioning magnet 414 can correspond to the initial ejection position of the camera module 200. The positioning magnet 415 can correspond to the end ejection position of the camera module 200. By providing the positioning magnet 414, the positioning magnet 415 and the displacement sensor 2721, it can be determined whether the camera module 200 is ejected to a specified height or whether the camera module 200 is retracted to a specified position, which is beneficial to improving the stability of the ejection and contraction of the camera module 200.
[0314] Continuing to combine Figure 4 and Figure 5 , in some embodiments provided by the present application, the lens assembly 220 can be fixedly connected to the ejection cover 240 through the focusing stator 225. The focusing stator 225 and the ejection cover 240 can be fixedly connected by one or more of the following: threaded fasteners, adhesives, welding, etc. In one embodiment, as Figure 4 shown, the camera module 200 can include a threaded fastener 280.
[0315] Fig. 27 is a schematic structural diagram of an ejection cover 240 provided by an embodiment of the present application.
[0316] The ejection cover 240 can include a cylindrical portion 241 and a cover portion 242. The cross section of the cylindrical portion 241 can be, for example, an annular shape, an elliptical annular shape or other shapes. The cover portion 242 can be provided and fastened to one end of the cylindrical portion 241. In a possible case, the cover portion 242 can be connected to the inner wall or the outer periphery of the cylindrical portion 241. The cover portion 242 can include a light-transmitting area. Light from the outside can pass through the light-transmitting area of the cover portion 242 to irradiate the plurality of lenses 221 of the lens assembly 220. The light-transmitting area and the plurality of lenses 221 can be disposed opposite to each other.
[0317] In one embodiment, the cover portion 242 may be entirely transparent, that is to say, the entire cover portion 242 may be the light-transmitting area of the cover portion 242. In another embodiment, the cover portion 242 may be provided with a light-transmitting hole 2421, and the area of the cover portion 242 within the light-transmitting hole 2421 may be the light-transmitting area of the cover portion 242. The area of the cover portion 242 outside the light-transmitting hole 2421 may be opaque. In a possible case, the center of the light-transmitting hole 2421 may be aligned with the optical axis.
[0318] In the present application, when component a and component b satisfy any of the following conditions, it can be considered that component a and component b are oppositely arranged: the projection area of component a is located within the projection area of component b; the projection area of component b is located within the projection area of component a; the projection areas of component a and component b intersect, and the intersection portion of the projection areas of component a and component b accounts for more than 50% of the projection area of component a or the projection area of component b.
[0319] In one embodiment, the pop-up cover 240 may further include a transparent cover plate 244. The transparent cover plate 244 may be disposed on the side of the cover portion 242 away from the lens assembly 220. The transparent cover plate 244 may cover the light-transmitting hole 2421. That is to say, the transparent cover plate 244 may be connected to the area of the cover portion 242 outside the light-transmitting hole 2421. The transparent cover plate 244 may be used to block external contaminants from entering the camera module 200 through the light-transmitting hole 2421. The transparent cover plate 244 may be attached to the cover portion 242 by a transparent optical adhesive tape, for example.
[0320] As Fig. 27 shown, the cover portion 242 of the pop-up cover 240 may have a mounting through-hole 2422. Looking at the camera module 200 along the Fig. 27 J-J cross-section shown, a cross-sectional view as shown in Fig.28 can be obtained. It should be noted that the Fig. 27 J-J cross-section shown may correspond to the Fig.16 J-J cross-section shown. A threaded hole 2252 may be provided on the side of the focusing stator 225 facing the cover portion 242 of the pop-up cover 240. A threaded fastener 280 may pass through the mounting through-hole 2422 on the pop-up cover 240 and cooperate with the threaded hole 2252, so as to realize the fixed connection between the pop-up cover 240 and the focusing stator 225.
[0321] In some embodiments, one of the pop-up cover 240 and the focusing stator 225 may be provided with a positioning protrusion 2423, and the other may be provided with a positioning hole 2253. The positioning protrusion 2423 may cooperate with the positioning hole 2253, which is beneficial to improving the positioning accuracy between the focusing stator 225 and the pop-up cover 240. As Fig. 27As shown, a positioning protrusion 2423 may be provided on one side of the cover portion 242 of the pop-up cover 240 facing the focusing stator 225. Along Fig. 27 Observing the camera module 200 along the K-K cross-section shown, the following can be obtained Fig.29 The cross-sectional view shown. It should be noted that Fig. 27 The K-K cross-section shown can correspond to Fig.16 The K-K cross-section shown. As Fig.29 shown, a positioning hole 2253 may be provided on one side of the focusing stator 225 facing the cover portion 242 of the pop-up cover 240. The positioning protrusion 2423 can extend into the positioning hole 2253.
[0322] Continuing to combine Figure 4 and Figure 5 , in some embodiments provided by the present application, the camera module 200 may further include a flexible connecting member 250. One end of the flexible connecting member 250 can be fixed to the camera bracket 210. The other end of the flexible connecting member 250 can be connected to the cylindrical portion 241 of the pop-up cover 240 and fastened to the opening of the cylindrical portion 241. The flexible connecting member 250 can be connected to the outer circumference or inner wall of the cylindrical portion 241. That is to say, the flexible connecting member 250 can be connected between the pop-up cover 240 and the camera bracket 210.
[0323] Due to the flexibility of the flexible connecting member 250 itself, when the pop-up cover 240 moves away from the camera bracket 210, the flexible connecting member 250 can extend (or unfold) along the optical axis. When the pop-up cover 240 moves closer to the camera bracket 210, the flexible connecting member 250 can contract (or fold) along the optical axis. In a possible case, the flexible connecting member 250 may also have relatively high sealing performance. For example, the flexible connecting member 250 may have waterproof performance. The flexible connecting member 250 can be hermetically connected between the camera bracket 210 and the pop-up cover 240, which is beneficial to reducing the possibility of external contaminants entering the cavity between the camera bracket 210 and the pop-up cover 240.
[0324] In some embodiments, as Fig. 27 and Fig.29 shown, a limiting claw 245 may be provided at one end of the pop-up cover 240 close to the camera bracket 210. Combining Fig.24 , the camera bracket 210 further includes a protruding portion 217 disposed opposite to the limiting claw 245. The protruding portion 217 extends from the bearing portion 211 of the camera bracket 210 toward the pop-up cover 240.
[0325] As Fig.24 and Fig.29As shown, a limiting platform 2171 is provided at one end of the protruding portion 217 close to the ejection cover 240. A claw chute 2151 extending along the optical axis is provided between the limiting platform 2171 and the bearing portion 211. The limiting claw 2452 can extend into the claw chute 2151 and move within the claw chute 2151. When the limiting claw 245 moves to the limiting platform 2171, the limiting claw 245 can cooperate with the limiting platform 2171, and the limiting platform 2171 can block the limiting claw 245 from continuing to move away from the camera bracket 210.
[0326] In one embodiment, as Fig.24 shown, the claw chute 2151 includes a chute portion 2152 and a chute portion 2153. The chute portion 2152 can be opposite to the limiting platform 2171. That is to say, the projection area of the limiting platform 2171 on the bearing portion 211 of the camera bracket 210 can be located within the projection area of the claw chute 2151 on the bearing portion 211. The chute portion 2153 can be located outside the projection area of the limiting platform 2171 in the projection area of the bearing portion 211. When assembling the ejection cover 240 and the camera bracket 210, the ejection cover 240 can rotate around the optical axis, so that the limiting claw 245 can slide from the chute portion 2153 into the chute portion 2152 and cooperate with the limiting platform 2171 within the chute portion 2152. When disassembling the ejection cover 240 and the camera bracket 210, the limiting claw 245 can slide into the chute portion 2153 through the chute portion 2152, and the limiting claw 245 can be unrestricted by the limiting platform 2171 within the chute portion 2153, so that the ejection cover 240 can be separated from the camera bracket 210.
[0327] In some embodiments, as Figure 4 、 Figure 5 and Figure 25 to Figure 27 shown, the ejection cover 240 may further include an outer extension ring 243. The outer extension ring 243 can surround the outer periphery of the cylindrical portion 241. The outer extension ring 243 and the cover portion 241 can be located at both ends of the cylindrical portion 242 respectively. The outer extension ring 243 can extend from the cylindrical portion 241 away from the optical axis. In a possible case, the outer extension ring 243 can be perpendicularly arranged relative to the optical axis.
[0328] As Figure 24 to Figure 26 shown, the protruding portion 212 of the camera bracket 210 can have an end face 2121. The end face 2121 can be located on the side of the protruding portion 212 away from the bearing portion 211. In a possible case, the end face 2121 can be perpendicularly arranged relative to the optical axis.
[0329] The flexible connecting member 250 may have a ring body 251, a ring body 252, and a ring body 253. The ring body 253 may be connected between the ring body 251 and the ring body 252. The outer diameter of the ring body 251 may be greater than the outer diameter of the ring body 252. The ring body 251 may be fixedly connected to the end face 2121 of the camera bracket 210. The ring body 252 may be fixedly connected to the outer extension ring 243 of the pop-up cover 240. The ring body 253 may be used to provide a deformation amount along the optical axis for the ring body 252, so that the ring body 252 can move along the optical axis relative to the ring body 251. When the pop-up cover 240 moves away from the camera bracket 210, the ring body 252 and one end of the ring body 253 close to the ring body 252 may move away from the camera bracket 210 following the pop-up cover 240. When the pop-up cover 240 moves closer to the camera bracket 210, the ring body 252 and one end of the ring body 253 close to the ring body 252 may move closer to the camera bracket 210 following the pop-up cover 240.
[0330] Combined with Figure 24 to Figure 26 , the pop-up cover 240 can move along the optical axis within the cavity surrounded by the protrusion 212. The outer peripheral dimension of the pop-up cover 240 may be smaller than the dimension of the cavity surrounded by the protrusion 212. In a possible case, the outer peripheral dimension of the pop-up cover 240 may correspond to the outer peripheral dimension of the outer extension ring 243.
[0331] Combined with Fig.25 , when the pop-up cover 240 is in the retracted state, the outer extension ring 243 of the pop-up cover 240 may be located at a position close to the bearing portion 211 and within the cavity surrounded by the protrusion 212. Since the ring body 252 is connected to the outer extension ring 243, the ring body 252 may be located within the cavity surrounded by the protrusion 212. The region of the ring body 253 close to the ring body 252 may be located within the cavity surrounded by the protrusion 212, and the region of the ring body 253 close to the ring body 251 may be located outside the cavity surrounded by the protrusion 212.
[0332] Combined with Fig.26 , when the pop-up cover 240 is in the popped-up state, the outer extension ring 243 of the pop-up cover 240 may move out of the cavity surrounded by the protrusion 212, and the entire flexible connecting member 250 may be located outside the cavity surrounded by the bearing portion 211 and the protrusion 212.
[0333] In one embodiment, the protrusion 212 may include a bearing platform 2122. The bearing platform 2122 may be located at one end of the protrusion 212 away from the end face 2121. In a possible case, the bearing platform 2122 may be perpendicularly arranged with respect to the optical axis. The bearing platform 2122 may be flush or not flush with the bearing portion 211. The bearing platform 2122 may be annular. The projection of the outer extension ring 243 on the camera bracket 210 may be located on the bearing platform.
[0334] When the pop-up cover 240 is in a contracted state, the outer extension ring 243 of the pop-up cover 240 directly or indirectly abuts against the bearing platform 2122. As Fig.25 and 26 shown, a buffer member 2123 is provided on the outer extension ring 243 of the pop-up cover 240. The buffer member 2123 can be located on a side of the outer extension ring 243 away from the cover portion 242. When the pop-up cover 240 is in a contracted state, the buffer member 2123 can contact the bearing platform 2122. The buffer member 2123 can buffer between the bearing platform 2122 and the outer extension ring 243, thereby facilitating reducing the vibration generated when the outer extension ring 243 impacts the bearing platform 2122.
[0335] Continuing to refer to Figure 4 and Figure 5 , in some embodiments provided by the present application, the pop-up assembly 230 can include a pop-up driving member 231 and a pop-up pushing member 232. The pop-up driving member 231 can be carried on the camera bracket 210. The pop-up driving member 231 can be used to drive the pop-up pushing member 232 to move along the optical axis. The pop-up pushing member 232 can be fixedly connected to the pop-up cover 240. Therefore, the pop-up cover 240 can move along the optical axis under the drive of the pop-up pushing member 232. Thus, the pop-up cover 240 can be moved relative to the camera bracket 210 along the optical axis. In some embodiments, the focusing stator 225 can have an avoidance recess structure for the pop-up driving member 231. The avoidance recess structure can be recessed from the side wall of the focusing stator 225 toward the optical axis. The pop-up driving member 231 can be close to or disposed within the avoidance recess structure to reduce the occupied space after the focusing stator 225 and the pop-up driving member 231 are assembled.
[0336] The pop-up assembly 230 can drive the pop-up pushing member 232 by the pop-up driving member 231 through mechanical transmission principles (such as a stepping motor), electromagnetic principles (such as a Hall magnet), piezoelectric principles (such as piezoelectric ceramics), etc. Fig.30 is a schematic structural diagram of a pop-up assembly 230 provided by an embodiment of the present application. Fig.30 The assembly relationship between the pop-up assembly 230 and the camera bracket 210 is also shown.
[0337] The ejection driving member 231 may include an ejection pusher receiving hole 2311 and an ejection pusher receiving hole 2312. The ejection pusher receiving hole 2311 and the ejection pusher receiving hole 2312 communicate with each other. The hole axis of the ejection pusher receiving hole 2312 may be aligned with the hole axis of the ejection pusher receiving hole 2312. The ejection pusher receiving hole 2311 is located at one end of the ejection driving member 231 close to the ejection cover 240. The ejection pusher receiving hole 2312 is located at one end of the ejection driving member 231 close to the camera bracket 210. The inner diameter of the ejection pusher receiving hole 2311 may be smaller than that of the ejection pusher receiving hole 2312. In a possible case, the ejection driving member 231 may have a piezoelectric ceramic. The ejection pusher receiving hole 2312 may be provided on the piezoelectric ceramic.
[0338] The ejection pusher 232 may be disposed in the ejection pusher receiving hole 2311 and the ejection pusher receiving hole 2312. The ejection pusher 232, the ejection pusher receiving hole 2311, and the ejection pusher receiving hole 2312 may extend along the optical axis. One end of the ejection pusher 232 away from the camera bracket 210 may extend out of the ejection pusher receiving hole 2311 and be fixedly connected to the ejection cover 240.
[0339] Combined Figure 4 、 Figure 5 and Fig. 27 , the ejection cover 240 may include a mounting through hole 2424. One end of the ejection pusher 232 away from the camera bracket 210 may extend into the mounting through hole 2424. A welding piece 2426 may be provided on one side of the ejection cover 240 away from the camera bracket 210. The edge region of the welding piece 2426 may be welded to the ejection cover 240, and the central region of the welding piece 2426 may be welded to the ejection pusher 232. Thus, the ejection pusher 232 may be fixedly connected to the ejection cover 240. The outer diameter of the ejection pusher 232 may be smaller than the aperture of the mounting through hole 2424, and the outer diameter of the welding piece 2426 may be larger than the aperture of the mounting through hole 2424.
[0340] In a possible case, as Figure 5 shown, an installation groove 2427 may be provided in the cover portion 242 of the ejection cover 240. The installation groove 2427 may be located on one side of the cover portion 242 away from the camera bracket 210. The opening of the installation groove 2427 may be set away from the camera bracket 210. The bottom of the installation groove 2427 may communicate with the mounting through hole 2424. The cover welding piece 2426 may be disposed in the installation groove 2427 and fixedly connected to the bottom of the installation groove 2427. By providing the installation groove 2427, it is beneficial to bury the cover welding piece 2426 in the installation groove 2427, so that there may be no obvious protrusion on the side of the ejection cover 240 away from the camera bracket 210, thereby being beneficial to increasing the contact area between the cover portion 242 and the transparent cover plate 244.
[0341] The ejecting pusher 232 can be formed by bending a sheet. As Fig.30 shown, the ejecting pusher 232 can be a tubular structure with a slit 2322. In a possible case, the slit 2322 of the ejecting pusher 232 can be arranged parallel to the optical axis. When the ejecting pusher 232 is not placed in the ejecting pusher receiving hole 2311 of the ejecting driving part 231, the slit 2322 of the ejecting pusher 232 can be relatively large. When the ejecting pusher 232 is placed in the ejecting pusher receiving hole 2311 of the ejecting driving part 231, the ejecting pusher 232 is squeezed by the hole wall of the ejecting pusher receiving hole 2311, so that the slit 2322 of the ejecting pusher 232 can be narrowed. Thus, the outer periphery of the ejecting pusher 232 can be pressed against the hole wall of the ejecting pusher receiving hole 2311, so that there can be a frictional force between the ejecting pusher 232 and the ejecting pusher receiving hole 2311. There can be a distance between the ejecting pusher 232 and the ejecting pusher receiving hole 2312.
[0342] When the ejecting driving part 231 is not working, there can be a static frictional force between the ejecting pusher 232 and the ejecting pusher receiving hole 2311, and this static frictional force can make the ejecting pusher 232 relatively stationary in the ejecting pusher receiving hole 2311. This is beneficial to making the ejecting pusher 232 hover in the ejecting pusher receiving hole 2311.
[0343] The ejecting driving part 231 can conduct a piezoelectric resonance signal. At the same moment, the displacement of one end of the ejecting driving part 231 close to the ejecting cover 240 can be in the opposite direction to the displacement direction of one end of the ejecting driving part 231 close to the camera bracket 210. For example, at the same moment, the part of the ejecting driving part 231 with the ejecting pusher receiving hole 2311 can move towards the ejecting cover 240, and the part of the ejecting driving part 231 with the ejecting pusher receiving hole 2312 can move towards the camera bracket 210. That is to say, the ejecting driving part 231 can be in an extended state. Another example is that at the same moment, the part of the ejecting driving part 231 with the ejecting pusher receiving hole 2311 can move towards the camera bracket 210, and the part of the ejecting driving part 231 with the ejecting pusher receiving hole 2312 can move towards the ejecting cover 240. That is to say, the ejecting driving part 231 can be in a contracted state. The ejecting driving part 231 can periodically switch between the extended state and the contracted state.
[0344] During the process of the ejecting pusher 232 moving towards the elastic cover, the time when the ejecting driving part 231 is in the extended state can be longer than the time when the ejecting driving part 231 is in the contracted state. That is to say, the extension speed of the ejecting driving part 231 is relatively slow, and the contraction speed of the ejecting driving part 231 is relatively fast.
[0345] During one cycle, when the ejection driving member 231 slowly extends, due to the frictional force between the ejection pushing member 232 and the ejection pushing member receiving hole 2311 of the ejection driving member 231, the ejection pushing member 232 can move towards the ejection cover 240 under the drive of the ejection driving member 231. The displacement amount of the ejection pushing member 232 moving towards the ejection cover 240 can be the same as or close to 50% of the extension amount of the ejection driving member 231. When the ejection driving member 231 quickly contracts, due to inertia, the displacement amount of the ejection pushing member 232 moving towards the camera bracket 210 is less than 50% of the contraction amount of the ejection driving member 231. Since the extension amount and the contraction amount of the ejection driving member 231 are the same during one cycle, therefore, during one cycle, the displacement amount of the ejection pushing member 232 moving towards the ejection cover 240 can be greater than the displacement amount of the ejection pushing member 232 moving towards the camera bracket 210. The ejection driving member 231 can repeatedly expand and contract in multiple cycles, so that the ejection pushing member 232 can be gradually moved out of the ejection pushing member receiving hole 2311.
[0346] The principle of the ejection pushing member 232 gradually moving back into the ejection pushing member receiving hole 2311 can refer to the embodiment in which the ejection pushing member 232 gradually moves out of the ejection pushing member receiving hole 2311.
[0347] As described above, at the same moment, the moving directions of both ends of the ejection driving member 231 are opposite, so the ejection driving member 231 can have a resonance zero point, and the displacement amount of the ejection driving member 231 at the resonance zero point can be zero. In a possible case, the ejection pushing member receiving hole 2311 and the ejection pushing member receiving hole 2312 can be respectively located on both sides of the resonance zero point.
[0348] In one embodiment, as Fig.30 shown, the camera bracket 210 can include a protrusion 215. The protrusion 215 can extend from the bearing portion 211 of the camera bracket 210 towards the ejection cover 240. In a possible case, the extending direction of the protrusion 215 can be parallel to the optical axis. An installation ear 2313 can be provided at a position near the resonance zero point on the ejection driving member 231, and the installation ear 2313 can be connected to the protrusion 215. Since the installation ear 2313 may vibrate slightly along the optical axis when the ejection driving member 231 works, the installation ear 2313 and the protrusion 215 can be connected by an elastic connecting member, and the elastic connecting member can be, for example, foam, silica gel, etc.
[0349] In some embodiments, as Fig.30As shown, a pop-up control element 275 may be provided on the circuit board assembly 270. Through the pop-up control element 275 on the circuit board assembly 270, the pop-up assembly 230 can be controlled to pop up or contract. In one embodiment, as described above, the circuit board assembly 270 may include a circuit board portion 271 and a circuit board portion 272. The pop-up control element 275 may be provided on the circuit board portion 272, for example. The pop-up driving member 231 may be electrically connected to the circuit on the circuit board portion 271. The circuit board portion 272 and the circuit board portion 271 may be electrically connected to each other. Therefore, the pop-up control element 275 can control the pop-up driving member 231 to reciprocate through the circuit board portion 272 and the circuit board portion 271.
[0350] Combined with Figure 5 and Fig.30 , in some embodiments provided in the present application, the camera bracket 210 may further be provided with a pop-up ring 216. The pop-up ring 216 may be provided on the bearing portion 211 of the camera bracket 210, and the pop-up ring 216 may be on the same side of the bearing portion 211 as the pop-up assembly 230. The pop-up ring 216 may surround the outer periphery of the pop-up driving member 231 of the pop-up assembly 230. The pop-up driving member 231 may reciprocate within the pop-up ring 216. The pop-up ring 216 may be used to limit the displacement amount of the pop-up driving member 231 deviating from the optical axis.
[0351] In one embodiment, the pop-up ring 216 may be provided on the camera bracket 210 by an in-mold process. As Figure 5 shown, the camera module 200 may include an in-mold portion 2161 of the pop-up ring 216 embedded in the camera bracket 210, and the remaining portion protrudes from the camera bracket 210. In a possible scenario, the in-mold portion 2161 of the pop-up ring 216 may be vertically arranged relative to the optical axis, and the remaining portion may protrude along the optical axis from the in-mold portion 2161.
[0352] The camera bracket 210 may be obtained by injection molding. The material of the camera bracket 210 may be resin, rubber, glass, etc., for example. Before injection molding, the in-mold component 2161 may be arranged in the injection mold. During the injection molding process, the raw material of the camera bracket 210 may wrap the in-mold portion 2161, so that the in-mold portion 2161 can be embedded in the camera bracket 210. This is beneficial to improving the connection stability between the pop-up ring 216 and the camera bracket 210.
[0353] In one embodiment, the pop-up assembly 230 may further include a pop-up counterweight 233. The pop-up counterweight 233 may be located at one end of the pop-up driving member 231 close to the camera bracket 210. The pop-up counterweight 233 may be beneficial to making the pop-up driving member 231 reciprocate regularly. The pop-up counterweight 233 may be provided on the pop-up ring 216, for example.
[0354] Continue to combine Figure 4 and Fig.16 , in some embodiments provided by the present application, the camera module 200 may further include a pop-up guiding component 290. The pop-up guiding component 290 may include a pop-up guide sleeve 291 and a pop-up guide rod 292. Observing the camera module 200 along the L-L cross-section shown in Fig.16 , a cross-sectional view shown in Fig.31 can be obtained.
[0355] The pop-up guide sleeve 291 may be disposed on the camera bracket 210. The pop-up guide rod 292 may be received in the pop-up guide sleeve 291. One end of the pop-up guide rod 292 away from the camera bracket 210 may be fixedly connected to the pop-up cover 240. The pop-up guide sleeve 291 and the pop-up guide rod 292 may extend along the optical axis. When the pop-up cover 240 moves along the optical axis relative to the camera bracket 210 along the optical axis, the pop-up cover 240 may drive the pop-up guide rod 292 to move along the optical axis. The pop-up guide sleeve 291 may be used to guide the pop-up guide rod 292, which is beneficial to reducing the displacement amount of the pop-up guide rod 292 deviating from the optical axis. In a possible case, Fig.31 shows two sets of pop-up guide sleeves 291 and pop-up guide rods 292. The distance between the first set of pop-up guide sleeves 291 and pop-up guide rods 292 may be less than 20 μm, and the distance between the second set of pop-up guide sleeves 291 and pop-up guide rods 292 may be greater than 50 μm. The first set of pop-up guide sleeves 291 and pop-up guide rods 292 may be used for installation and positioning, and the second set of pop-up guide sleeves 291 and pop-up guide rods 292 may be used to provide an interference margin.
[0356] In a possible case, the azimuth angles of the pop-up guide sleeve 291 and the pop-up driving member 231 relative to the optical axis are 45° to 135°. That is to say, when projected along the optical axis direction, the connection line between the center of the projection area of the pop-up guide sleeve 291 and the optical axis is connection line a, and the connection line between the center of the projection area of the pop-up driving member 231 and the optical axis is connection line b. The angle between connection line a and connection line b is 45° to 135°. The pop-up guide sleeve 291 and the pop-up driving member 231 may guide the focusing stator 225 from different azimuths, which is beneficial to reducing the displacement amount of the focusing stator 225 deviating from the optical axis.
[0357] In a possible case, the azimuth angles of the ejection driving member 231 and the focusing driving member 227 with respect to the optical axis are 15° to 180°. That is, when projected along the optical axis direction, the line connecting the center of the projection area of the ejection driving member 231 and the optical axis is line c, and the line connecting the center of the projection area of the ejection driving member 231 and the optical axis is line d, and the angle between line c and line d is 15° to 180°. The ejection driving member 231 can be used to drive the focusing stator 226 to move along the optical axis, and the focusing driving member 227 can be used to drive the focusing rotor 225 to move along the optical axis. That is to say, the ejection assembly 230 and the focusing assembly 222 can be arranged at different azimuths of the camera module 200. Therefore, it is beneficial to make the ejection assembly 230 and the focusing assembly 222 assembled relatively compactly within the camera module 200.
[0358] Combined with Figure 4 、 Fig. 27 and Fig.31 , the ejection cover 240 may include an installation through hole 2425. One end of the ejection guide rod 292 away from the camera bracket 210 can extend into the installation through hole 2425. A welding piece 2428 can be arranged on the side of the ejection cover 240 away from the camera assembly. The edge area of the cover welding piece 2428 can be welded to the ejection cover 240, and the central area of the welding piece 2428 can be welded to the ejection guide rod 292. Thus, the ejection guide rod 292 can be fixedly connected to the ejection cover 240. The outer diameter of the ejection guide rod 292 can be smaller than the aperture of the installation through hole 2425, and the outer diameter of the welding piece 2428 can be larger than the aperture of the installation through hole 2425.
[0359] In a possible case, an installation groove 2429 can be provided in the cover portion 242 of the ejection cover 240, and the installation groove 2429 can be located on the side of the cover portion 242 away from the camera bracket 210. The opening of the installation groove 2429 can be set away from the camera bracket 210. The bottom of the installation groove 2429 can communicate with the installation through hole 2425. The cover welding piece 2428 can be arranged in the installation groove 2429 and fixedly connected to the bottom of the installation groove 2429. By providing the installation groove 2429, it is beneficial to bury the cover welding piece 2428 in the installation groove 2429, so that there may be no obvious protrusions on the side of the ejection cover 240 away from the camera bracket 210, which is beneficial to increasing the contact area between the cover portion 242 and the transparent cover plate 244.
[0360] In other embodiments provided by the present application, the pop-up cover 240 can be driven to move relative to the camera bracket 210 by a stepper motor. However, the stepper motor and related speed-changing transmission components, etc., occupy a relatively large space. In addition, the stepper motor can rotate the lens to move the lens along the optical axis. During the process of the stepper motor rotating the lens, it is very difficult to control the displacement amount of the lens deviating from the optical axis. The camera module usually has a relatively large number of lenses. During the pop-up process, it is relatively difficult to align the centers of multiple lenses, which will affect the imaging effect. The stepper motor is also prone to introducing noise, which affects the video shooting quality. The pop-up component provided by the present application can apply the piezoelectric principle. The occupied space of the pop-up component is relatively small. The focusing stator 225 can move linearly along the optical axis following the pop-up cover 240, which is beneficial to reducing the displacement amount of the focusing stator 225 deviating from the optical axis, and the noise caused by the pop-up component is relatively small.
[0361] In other embodiments provided by the present application, the pop-up cover 240 can be driven to move relative to the camera bracket 210 by a Hall magnet. However, when the space occupied by the Hall magnet is reasonable, the stroke that the Hall magnet can achieve is relatively short. In the embodiments provided by the present application, the pop-out stroke of the pop-up cover 240 can be relatively large. To meet the stroke requirements, multiple Hall magnets can be arranged in the camera module 200. However, multiple Hall magnets may interfere with each other. By driving with Hall magnets, a self-locking module also needs to be set up additionally. The focusing component provided by the present application can apply the piezoelectric principle, and can achieve a relatively long pop-out stroke in a relatively small space, which is beneficial to taking into account requirements such as stroke and occupied space.
[0362] Figure 3 Fig. 7 shows a schematic structural diagram of a camera module 200 provided by an embodiment of the present application in a contracted state. Fig.32 Fig. 9 shows a schematic structural diagram of a camera module 200 provided by an embodiment of the present application in a pop-up state.
[0363] Along Fig.16 Viewing the camera module 200 along the A-A cross-section shown in Fig. 14, the cross-sectional views shown in Figs. 15, 17 and 20 can be obtained. Figure 5 、 Fig.33 and Fig.35 the cross-sectional views shown in Fig. 20. Figure 5 The camera module 200 shown in Fig. 22 is in a contracted state, Fig.33 The camera module 200 shown in Fig. 24 is in a pop-up state, Fig.35 The camera module 200 shown in Fig. 26 is in a focusing mode in the pop-up state.
[0364] Along Fig.16 Viewing the camera module 200 along the L-L cross-section shown in Fig. 31, the cross-sectional views shown in Figs. 32, 34 and 37 can be obtained. Fig.31 、 Fig.34 and Fig.36 the cross-sectional views shown in Fig. 37. Fig.31 The camera module 200 is shown in a retracted state. Fig.34 The camera module 200 is shown in a pop-up state. Fig.36 The camera module 200 is shown in a focus mode in the pop-up state.
[0365] Combine the following Figure 5 , Figure 31 to Figure 36 , explaining the pop-up principle of the camera module 200.
[0366] Figure 5 and Fig.31 A schematic structural diagram of the camera module 200 in a retracted state is shown. When the camera module 200 is in a retracted state, the distance between the pop-up hood 240 and the camera bracket 210 is relatively close, and the distance between the lens assembly 220 and the camera bracket 210 is relatively close. In a possible scenario, the buffer 2123 on the outer ring 243 of the pop-up hood 240 can contact the supporting platform 2122 of the camera bracket 210; a gap can be formed between the barrel 241 of the pop-up hood 240 and the protrusion 212 of the camera bracket 210, and the ring body 252 of the flexible connector 250 can be located in the gap. Figure 5 As shown, the ejection pusher 232 of the ejection assembly 230 can be accommodated in the ejection pusher receiving hole 2312 of the ejection driving member 231. Fig.31 As shown, most of the ejection guide rod 292 of the ejection guide assembly 290 can be accommodated in the ejection guide sleeve 291.
[0367] Since the space enclosed by the pop-up cover 240 and the camera bracket 210 is relatively small, the spacing between the lens group 223 and the lens group 224 is relatively small, and the spacing between the lens group 224 and the circuit board assembly 300 is relatively small. In a possible scenario, a buffer 416 is provided on the side of the focus actuator 226 facing the focus stator 225, and the buffer 416 can contact the side of the focus stator 225 facing the focus actuator 226; a buffer 417 is provided on the side of the focus actuator 226 away from the focus stator 225, and the buffer 417 can contact the circuit board assembly 270 on the camera bracket 210; the focus stopper 420 can surround the end of the focus stator 225 close to the pop-up cover 240.
[0368] Figure 33 to Figure 35 A schematic structural diagram showing the camera module 200 in a pop-up state is shown.
[0369] The camera module 200 can drive the pop-up cover 240 to move along the optical axis through the pop-up assembly 230, so that the pop-up cover 240 can move away from the camera bracket 210. The pop-up guide assembly 290 can guide the movement of the pop-up cover 240 to reduce the displacement of the pop-up cover 240 from the optical axis. The pop-up cover 240 can be fixedly connected to the focus stator 225, and the pop-up cover 240 can drive the focus stator 225 to move away from the camera bracket 210.
[0370] When the camera module 200 is in the pop-up state, the distance between the pop-up cover 240 and the camera bracket 210 is relatively far, and the distance between the focus stator 225 and the camera bracket 210 is relatively far. In a possible scenario, the pop-up cover 240 and the flexible connector 250 can be moved out of the space surrounded by the camera bracket 210 as a whole, and driven by the pop-up cover 240, the focus stator 225 can be moved out of the space surrounded by the camera bracket 210 as a whole. The pop-up pusher 232 of the pop-up assembly 230 can be moved out of the pop-up pusher accommodating hole 2312 of the pop-up driving member 231. Most of the pop-up guide rod 292 of the pop-up guide assembly 290 can be moved out of the pop-up guide sleeve 291.
[0371] In one possible scenario, Fig.33 and Fig.34 As shown, the focus actuator 226 can follow the focus stator 225 to move away from the camera bracket 210. That is, the spacing between the lens group 223 and the lens group 224 can be relatively small, and the spacing between the lens group 224 and the circuit board assembly 300 can be relatively large. A buffer 416 is provided on the side of the focus actuator 226 facing the focus stator 225, and the buffer 416 can be in contact with the focus stator 225; the focus limiter 420 can surround the end of the focus stator 225 close to the pop-up cover 240. A buffer 417 is provided on the side of the focus actuator 226 away from the focus stator 225, and the interval space between the buffer 417 and the camera bracket 210 can be the movable space of the focus actuator 226. That is to say, the focus actuator 226 can move toward the camera bracket 210. Fig.34 and Fig.35 In the scenario shown, the camera module 200 can, for example, capture wide-angle images.
[0372] In another possible scenario, the focusing mover 226 may not move away from the camera bracket 210 following the focusing stator 225. That is to say, the distance between the lens group 223 and the lens group 224 may be relatively large, and the distance between the lens group 224 and the circuit board assembly 300 may be relatively small. A buffer member 417 is provided on the side of the focusing mover 226 facing away from the focusing stator 225, and the buffer member 417 may be attached to the camera bracket 210; a focusing limit member 420 may surround one end of the focusing stator 225 close to the camera bracket 210. A buffer member 416 is provided on the side of the focusing mover 226 facing the focusing stator 225, and the spaced space between the buffer member 416 and the focusing stator 225 may be the movable space of the focusing mover 226. That is to say, the focusing mover 226 may move towards the pop-up cover 240.
[0373] In yet another possible scenario, the focusing mover 226 may move away from the camera bracket 210, but the displacement of the focusing mover 226 may be less than the displacement of the focusing stator 225. That is to say, there may be a spaced space between the focusing mover 226 and the focusing stator 225, and there may be a spaced space between the focusing mover 226 and the camera bracket 210. The focusing mover 226 may move towards the camera bracket 210 or towards the pop-up cover 240.
[0374] Fig.35 and Fig.36 Fig. shows a schematic structural diagram of the camera module 200 in a focusing mode.
[0375] In one embodiment, when the camera module 200 is in the pop-up state, the camera module 200 may enter the focusing mode. That is to say, after the camera module 200 is fully popped up, the camera module 200 may perform focusing. In another embodiment, when the camera module 200 is not fully popped up, that is to say, when the camera module 200 is between the retracted state and the pop-up state, the camera module 200 may enter the focusing mode. That is to say, when the camera module 200 is not fully popped up, the camera module 200 may perform focusing. The space between the focusing stator 225 and the camera bracket 210 may be the movable space of the focusing mover 226.
[0376] When the camera module 200 is in focus mode, there may be a spacing space between the focus actuator 226 and the focus stator 225. There may or may not be a spacing space between the focus actuator 226 and the camera bracket 210. In one possible scenario, a buffer 416 is provided on the side of the focus actuator 226 facing the focus stator 225, and there may be a spacing space between the buffer 416 and the focus stator 225; a buffer 417 is provided on the side of the focus actuator 226 facing away from the focus stator 225, and the buffer 417 may be attached to the camera bracket 210, or there may be a spacing space between the buffer 417 and the camera bracket 210. In one embodiment, by adjusting the distance between the focus actuator 226 and the focus stator 225, focusing can be achieved in a macro scene.
[0377] In a macro scene, the distance between the camera module 200 and the object (person) is relatively small. Compared with the overall focusing of the lens group 223 and the lens group 224, the lens group 224 is used alone for focusing, which is conducive to improving the viewing angle in the macro scene. Therefore, within the effective focusing range of the camera module 200, the distance between the camera module 200 and the object (person) can be relatively small.
[0378] Fig.37 It is a schematic structural diagram of a camera module 200 provided in this application. Fig.38 2 is an exploded view of a camera module 200 provided in this application. Fig.37 and Fig.38 In some embodiments provided in the present application, the camera module 200 may further include a dustproof component 430 .
[0379] The dustproof assembly 430 may include a dustproof cover plate 431 and a dustproof net 432. The dustproof cover plate 431 may include a dustproof cover plate body 433 and a dustproof cover plate protrusion 434.
[0380] The dust cover body 433 may be provided with a dustproof through hole 435. The dustproof net 432 may cover the dustproof through hole 435, thereby facilitating the reduction of pollutants entering the camera module 200 through the dustproof through hole 435. In one embodiment, the dustproof net 432 may be provided inside the camera module 200, that is, the dustproof net 432 may be provided on one side of the dust cover body 433 close to the camera bracket 210.
[0381] The area of the dust cover body 433 outside the dustproof through hole 435 can be sealed and connected to the camera bracket 210 and the circuit board assembly 300. Fig.38 As shown, the protrusion 212 of the camera bracket 210 may have a protrusion end 2124 and a protrusion end 2125. Figure 5, the end face 2121 of the protrusion 212 connected to the flexible connecting member 250 can extend from the protrusion end 2124 to the protrusion end 2125 around. The area of the dust-proof cover body 433 located outside the dust-proof through hole 435 can be hermetically connected to the protrusion end 2124, the protrusion end 2124 and the side wall of the circuit board assembly 300.
[0382] The dust-proof cover protrusion 434 can be located on the side of the dust-proof cover body 433 close to the flexible connecting member 250, and protrude from the dust-proof cover body 433 away from the camera bracket 210. The dust-proof cover protrusion 434 can be hermetically connected to the flexible connecting member 250.
[0383] By arranging that the dust-proof cover 431 can be hermetically connected to the camera bracket 210, the circuit board assembly 300, and the flexible connecting member 250, the flexible connecting member 250 and the camera bracket 210 are hermetically connected, and the circuit board assembly 300 and the camera bracket 210 are hermetically connected, it is beneficial to reduce the possibility of external pollutants entering the inside of the camera module 200.
[0384] When the camera module 200 changes from the contracted state to the popped-up state, air can enter the inside of the camera module 200 through the dust-proof net 432; when the camera module 200 changes from the popped-up state to the contracted state, air can be discharged to the outside of the camera module 200 through the dust-proof net 432. Therefore, it is beneficial to make the air pressure inside the camera module 200 match the external air pressure during the process of the change of the internal volume of the camera module 200.
[0385] The multiple pins 301 on the circuit board assembly 300 and the multiple pins 273 of the circuit board assembly 270 can be arranged close to the dust-proof assembly 430. When the dust-proof assembly 430 is disassembled from the camera module 200, the multiple pins 301 and the multiple pins 273 can be exposed through the opening surrounded by the flexible connecting member 250, the camera module 200 and the circuit board assembly 300, so that it is beneficial to perform maintenance, detection, adjustment, etc. on the multiple pins 301 and the multiple pins 273 under the condition of relatively small disassembly degree of the camera module 200.
[0386] Continue to combine Figure 5 , in some embodiments provided by the present application, the camera bracket 210 can include a protruding portion 218, and the protruding portion 218 can protrude from the bearing portion 211 of the camera bracket 210 toward the circuit board assembly 300. In one embodiment, the protruding direction of the protruding portion 218 can be parallel to the optical axis. The protruding portion 218 can surround the outer periphery of the bearing portion 211. The space surrounded by the protruding portion 218 and the bearing portion 211 can be used to accommodate the components on the circuit board assembly 300. The end face of the protruding portion 218 away from the bearing portion 211 can be fixedly connected to the circuit board assembly 300.
[0387] Fig.39 FIG. 2 is a schematic structural diagram of a circuit board assembly 300 provided by an embodiment of the present application. Figure 40 FIG. 3 is an exploded view of a circuit board assembly 300 provided by an embodiment of the present application. As Figure 39 and Figure 40 shown, the circuit board assembly 300 may include a circuit board 320 and a reinforcing plate 330. The reinforcing plate 330 may be located on a side of the circuit board 320 away from the camera bracket 210. Components may be provided on a side of the circuit board 320 away from the reinforcing plate 330. The reinforcing plate 330 may be adhered to the circuit board 320 as a single body, so that the structure formed by the reinforcing plate 330 and the circuit board 320 can meet the strength requirements.
[0388] Combined with Figure 39 and Figure 40 In some embodiments provided by the present application, the circuit board assembly 300 may further include a module base 340. In some other embodiments, the module base 340 may be a component of the camera module 200. The module base 340 may be fixedly connected to a side of the reinforcing plate 330 away from the circuit board 320. The module base 340 may be used to reduce the possibility of external contaminants entering the camera module 200 through the circuit board assembly 300. The module base 340 may include a base bracket and a base plate. In one embodiment, the base plate may be fixed within the base bracket by insert molding. The base bracket may be fixedly connected to the reinforcing plate 330. The base plate and the reinforcing plate 330 may be parallel to each other and spaced apart. The base bracket may surround the outer periphery of the base plate. The base plate may be, for example, a metal plate, which is beneficial to heat dissipation of the camera module 200 and also beneficial to shielding external signals.
[0389] Viewing the circuit board 320 along the optical axis shown in Figure 40 FIG. 4, a structural diagram shown in Figure 41 FIG. 5 can be obtained. Viewing the reinforcing plate 330 along the optical axis shown in Figure 40 FIG. 6, a structural diagram shown in Figure 42 FIG. 7 can be obtained.
[0390] The circuit board 320 may include a circuit board portion 321, a circuit board portion 322, and a circuit board portion 323. In one embodiment, the circuit board 320 may be a rigid-flexible board. The circuit board portion 321 and the circuit board portion 322 may be rigid boards. The circuit board portion 323 may be a flexible board. The circuit board portion 322 may surround the outer periphery of the circuit board portion 321. The circuit board portion 323 may be connected to the outer periphery of the circuit board portion 322. Combined with Figure 31 and Figure 41, one end of the circuit board part 323 away from the circuit board part 322 may be provided with pins 302. The pins 302 can be used to enable signal interaction between the camera module 200 and other components within the electronic device. Pins 301 may be provided on the circuit board part 322. The pins 301 may be located, for example, in the outer edge area of the circuit board part 322. In combination with Figure 18 and Figure 41 , the pins 302 can be used for electrical connection with the pins 273 on the circuit board assembly 270.
[0391] The reinforcing plate 330 may be a plate member with sufficient strength. The material of the reinforcing plate 330 may be, for example, metal. The strength of the reinforcing plate 330 may be higher than that of the circuit board 320, so as to provide reinforcement for the circuit board 320. The reinforcing plate 330 may include a reinforcing plate part 331 and a reinforcing plate part 332. In combination with Figure 41 and Figure 42 , the reinforcing plate part 331 may be attached to the circuit board part 321, and the reinforcing plate part 332 may be attached to the circuit board part 322. The outer contour of the projection of the reinforcing plate part 331 along the optical axis may match the outer contour of the projection of the circuit board part 321 along the optical axis. The outer contour of the projection of the reinforcing plate part 332 along the optical axis may match the outer contour of the projection of the circuit board part 322 along the optical axis. In the embodiments provided in the present application, the outer contours of the projections of component a and component b matching may satisfy one or more of the following: the same shape, similar shapes, the same size, and approximately the same size.
[0392] As Figure 41 shown, the circuit board part 321 and the circuit board part 322 may be connected by one or more traces. The reinforcing plate part 331 and the reinforcing plate part 332 may be connected by one or more reinforcing traces. One or more traces between the circuit board part 321 and the circuit board part 322 may be arranged in one-to-one correspondence and oppositely with one or more reinforcing traces between the reinforcing plate part 331 and the reinforcing plate part 332. The traces may be attached to the corresponding reinforcing traces. Along the optical axis, the projection area of the traces may mostly overlap with the projection area of the reinforcing traces.
[0393] In the embodiments of the present application, the projection areas of component a and component b mostly overlapping may satisfy any one of the following: the projection area of component a is located within the projection area of component b; the projection area of component b is located within the projection area of component a; the proportion of the intersection part of the projection areas of component a and component b in the projection area of component a or component b exceeds 50%.
[0394] As Figures 18 to 20As shown, the circuit board portion 321 and the circuit board portion 322 can be connected by a plurality of traces 324. The reinforcement plate portion 331 and the reinforcement plate portion 332 can be connected by a plurality of reinforcement traces 334. The plurality of traces 324 and the plurality of reinforcement traces 334 can form a trace suspension assembly (TSA).
[0395] The circuit board portion 322 can include a circuit board receiving groove 3221, and the circuit board portion 321 and the traces 324 can be received in the circuit board receiving groove 3221. Among them, the traces 324 can be located in the spaced space between the circuit board portion 321 and the circuit board portion 322. The circuit board portion 321 can include a circuit board protrusion 3211, and the circuit board portion 322 can include a circuit board protrusion 3222. The circuit board protrusion 3211 and the circuit board protrusion 3222 can be staggeredly arranged. That is to say, the projection areas of the circuit board protrusion 3211 and the circuit board protrusion 3222 along the optical axis can not overlap each other. One or more traces 324 can include a trace 3241, and the trace 3241 can be connected between the circuit board protrusion 3211 and the circuit board protrusion 3222.
[0396] In one embodiment, the circuit board protrusion 3211 can protrude from the side wall 3213 of the circuit board portion 321 toward the groove wall 3224 of the circuit board receiving groove 3221, and the circuit board protrusion 3222 can protrude from the groove wall 3225 of the circuit board receiving groove 3221 toward the side wall 3214 of the circuit board portion 321, where the side wall 3213 and the side wall 3214 of the circuit board portion 321 can be two different side walls of the circuit board portion 321, and the groove wall 3224 and the groove wall 3225 of the circuit board receiving groove 3221 can be two different groove walls of the circuit board receiving groove 3221.
[0397] The reinforcement plate portion 332 can include a reinforcement plate receiving groove 3321, and the reinforcement plate portion 331 and the reinforcement traces 334 can be received in the reinforcement plate receiving groove 3321. Among them, the reinforcement traces 334 can be located in the spaced space between the reinforcement plate portion 331 and the reinforcement plate portion 332. The reinforcement plate portion 331 can include a reinforcement plate protrusion 3311, and the reinforcement plate portion 332 can include a reinforcement plate protrusion 3322. Combined Figure 41 and Figure 42, the reinforcing plate protrusion 3311 can be disposed opposite to the circuit board protrusion 3211, and the circuit board protrusion 3211 can be attached to the reinforcing plate protrusion 3311. The reinforcing plate protrusion 3322 can be disposed opposite to the circuit board protrusion 3222, and the circuit board protrusion 3222 can be attached to the reinforcing plate protrusion 3322. That is to say, the projection areas of the reinforcing plate protrusion 3311 and the circuit board protrusion 3211 along the optical axis can mostly overlap, and the projection areas of the reinforcing plate protrusion 3322 and the circuit board protrusion 3222 along the optical axis can mostly overlap. One or more reinforcing traces 334 can include a reinforcing trace 3341, and the reinforcing trace 3341 can be connected between the reinforcing plate protrusion 3311 and the reinforcing plate protrusion 3322. The reinforcing trace 3341 can correspond to the trace 3241.
[0398] In one embodiment, the reinforcing plate protrusion 3311 can protrude from the side wall 3313 of the reinforcing plate portion 331 toward the groove wall 3324 of the reinforcing plate receiving groove 3321, and the reinforcing plate protrusion 3322 can protrude from the groove wall 3325 of the reinforcing plate receiving groove 3321 toward the side wall 3314 of the reinforcing plate portion 331.

[0399] Along Figure 39 the N-N cross-section shown to observe the circuit board assembly 300, a cross-sectional view as shown in Figure 43 can be obtained.
[0400] Combining Figures 41 to 43 , in some embodiments provided in the present application, the circuit board 320 can further include a light-transmitting hole 325, and the reinforcing plate 330 can further include a light-transmitting hole 335. The light-transmitting hole 325 and the light-transmitting hole 335 can be disposed opposite to each other and communicate with each other. In a possible case, along the optical axis, the projection areas of the light-transmitting hole 325 and the light-transmitting hole 335 can mostly overlap. As Figure 43As shown, the image sensor 310 can be fixed to one side of the reinforcement plate portion 331 away from the circuit board portion 321. The circuit board assembly 300 can also include leads 326, which can pass through the light-transmitting holes 325 and 335 and be electrically connected between the image sensor 310 and the circuit board 321. The light from the lens assembly 220 can pass through the light-transmitting holes 325 and 335 and be incident on the image sensor 310. Along the optical axis, the imaging area of the image sensor 310 can be located within the projection area of the light-transmitting hole 325 or the light-transmitting hole 335.
[0401] In some other embodiments, for example, through the chip On board (COB) process, the image sensor 310 can also be disposed on one side of the circuit board portion 321 away from the reinforcement plate portion 331.
[0402] Combined Figure 41 , an SMA wire 311, an SMA wire fixing bracket 315, an SMA wire movable bracket 317, and an SMA wire control module 329 can also be provided on the circuit board 320.
[0403] The SMA wire 311 can be disposed opposite to the trace 3241. In some embodiments, the SMA wire 311 being disposed opposite to the trace 3241 can mean that along the direction perpendicular to the SMA wire, the projection area of the trace 3241 can at least partially overlap with the projection area of the SMA wire 311. In one embodiment, the trace 3241 can include a trace portion 3241a, and the trace portion 3241a can be disposed parallel or approximately parallel to the SMA wire 311.
[0404] Both ends of the SMA wire 311 can be connected to the SMA wire fixing bracket 315 and the SMA wire movable bracket 317.
[0405] The SMA wire fixing bracket 315 is fixed to the circuit board portion 322. One end of the SMA wire 311 connected to the SMA wire fixing bracket 315 can be the stator end of the SMA wire 311.
[0406] The first end of the SMA wire movable bracket 317 can be fixed to the circuit board portion 321. The SMA wire movable bracket 317 can extend from the circuit board portion 321 toward the circuit board portion 322 and be suspended above the circuit board portion 322. The projection area of the second end of the SMA wire movable bracket 317 on the circuit board 320 can be located on the circuit board portion 322. The SMA wire movable bracket 317 can undergo elastic deformation, so the second end of the SMA wire movable bracket 317 can be movable relative to the circuit board portion 322. The second end of the SMA wire movable bracket 317 can be connected to the SMA wire 311. One end of the SMA wire 311 connected to the SMA wire movable bracket 317 can be the rotor end of the SMA wire 311.
[0407] Through the SMA wire control module 329, the energization and de-energization of the SMA wire 311 can be controlled. In some embodiments, the SMA wire control module 329 can be disposed on the circuit board portion 321. The SMA wire control module 329 can realize the electrical connection between the SMA wire control module 329 and the stator end of the SMA wire 311 through the circuit board protrusion 3211 of the circuit board portion 321, the trace 3241, the circuit board protrusion 3222 of the circuit board portion 322, and the SMA wire fixing bracket 315. The SMA wire control module 329 can also realize the electrical connection between the SMA wire control module 329 and the mover end of the SMA wire 311 through the circuit board portion 321 and the SMA wire movable bracket 317.
[0408] In one embodiment, the SMA wire control module 329 can be located on one side of the light-transmitting hole 325. In a possible case, a weight element 328 can be disposed on the side of the light-transmitting hole 325 away from the driving module, so that the weight of the circuit board portion 321 can be balanced with respect to the optical axis.
[0409] After the SMA wire 311 is energized, the SMA wire 311 can contract due to heat. The SMA wire 311 can pull the second end of the SMA wire movable bracket 317 to move toward the SMA wire fixing bracket 315. Since the SMA wire movable bracket 317 is fixed to the circuit board portion 321, under the traction of the SMA wire 311, the portion of the circuit board portion 321 fixedly connected to the SMA wire movable bracket 317 can move toward the portion of the circuit board portion 322 fixedly connected to the SMA wire fixing bracket 315. Therefore, the circuit board portion 321 can deflect or move driven by the SMA wire 311. The circuit board portion 321 can drive the image sensor 310 to deflect or move, thereby realizing the anti-shake function of the camera module 200. Also, since the trace 3241 and the SMA wire 311 connected between the circuit board portion 321 and the circuit board portion 322 are disposed opposite to each other, the trace 3241 can undergo compressive elastic deformation. The trace 3241 is adhered to the reinforcing trace 3341, so the reinforcing trace 3341 can also undergo compressive elastic deformation.
[0410] When the SMA wire 311 is de-energized, the SMA wire 311 elongates when cooled, and the trace 3241 and the reinforcing trace 3341 can undergo elastic recovery of elongation, and the circuit board portion 321 can move toward the original position under the action of the trace 3241 and the reinforcing trace 3341.
[0411] In Figures 18 to 20In the illustrated embodiment, the circuit board portion 321 may further include a circuit board protrusion 3212, and the circuit board portion 322 may further include a circuit board protrusion 3223.

When the SMA wire 314 is powered off, the SMA wire 314 elongates when cooled, and the trace part 3243b of the trace 3243, the trace part 3244a of the trace 3244, the reinforced trace part 3343b of the reinforced trace 3343, and the reinforced trace part 3344a of the reinforced trace 3344 can undergo elongation elastic recovery, and then the circuit board part 321 can move towards the initial position.
[0436] In some embodiments, a plurality of traces 3241 may be connected between the circuit board protrusion 3211 and the circuit board protrusion 3222. As described above, when the SMA wire 311 shortens, the trace 3241 can resist the shortening of the SMA wire 311 through elastic compression; when the SMA wire 311 elongates, the trace 3241 can support the elongation of the SMA wire 311 through springback. To enable the plurality of traces 3241 to be spaced apart during deformation, that is, the deformations of the plurality of traces 3241 do not interfere with each other, a linkage trace 327 may be connected between adjacent two traces 3241, such as Figure 41as shown in the enlarged view. The above-mentioned trace portion 3241a and trace portion 3241b can be respectively located on both sides of the linkage trace 327.
[0437] In one embodiment, the extending direction of the linkage trace 327 can be inclined relative to the trace portion 3241a and inclined relative to the trace portion 3241b. Thus, the acting force borne by the linkage trace 327 can include a component force along the extending direction of the trace portion 3241a and a component force along the extending direction of the trace portion 3241b.
[0438] A plurality of reinforcing traces 3341 can be connected between the reinforcing plate protrusion 3311 and the reinforcing plate protrusion 3322. The plurality of reinforcing traces 3341 can correspond to the plurality of traces 3241 one by one. The reinforcing trace 3341 can be disposed opposite to the corresponding trace 3241, and the reinforcing trace 3341 can be attached to the corresponding trace 3241. A linkage reinforcing trace 337 can be connected between two adjacent reinforcing traces 3341. The linkage reinforcing trace 337 can be disposed opposite to the linkage trace 327, and the linkage reinforcing trace 337 can be attached to the linkage trace 327. The reinforcing trace portion 3341a and the reinforcing trace portion 3341b can be respectively located on both sides of the linkage reinforcing trace 337.
[0439] In a possible case, a plurality of linkage traces 327 can be connected between two adjacent traces 3241. As Figure 41 shown, the plurality of linkage traces 327 can include a linkage trace 327a and a linkage trace 327b. A connecting trace portion 3241c can be connected between the linkage trace 327a and the linkage trace 327b. The trace portion 3241c can be a part of the trace 3241. The trace portion 3241c can be connected between the trace portion 3241a and the trace portion 3241b.
[0440] Among the plurality of traces 3241, the closer to the circuit board portion 321, the shorter the length of the trace 3241 can be; the closer to the circuit board portion 322, the longer the length of the trace 3241 can be. The trace portion 3241a and the trace portion 3241b can be the main parts for the trace 3241 to support the deformation of the SMA wire 311. If the lengths of the trace portions 3241a of the plurality of traces 3241 are different, the deformation amounts of the plurality of trace portions 3241a can have a relatively large difference. Similarly, if the lengths of the trace portions 3241b of the plurality of traces 3241 are different, the deformation amounts of the plurality of trace portions 3241b can have a relatively large difference.
[0441] If there is a large difference in the amount of deformation in the main parts of multiple traces 3241 for supporting the deformation of the SMA wire 311, the multiple traces 324 may easily interfere with each other, thereby affecting the effective support of the multiple traces 3241 for the SMA wire 311. Therefore, by providing the linkage traces 327a and the linkage traces 327b, the traces 3241 can be divided into a trace part 3241a, a trace part 3241b, and a trace part 3241c. Since the lengths of the trace parts 3241c of the multiple traces 3241 can be different, it is convenient to make the lengths of the trace parts 3241a of the multiple traces 3241 substantially the same, and the lengths of the trace parts 3241b of the multiple traces 3241 substantially the same. This can help reduce the possibility of interference between the multiple traces 3241 due to a large difference in the amount of deformation of the multiple traces 3241.
[0442] Similarly, a plurality of linkage reinforcing traces 337 may be connected between two adjacent reinforcing traces 3341. As Figure 42 shown, the plurality of linkage reinforcing traces 337 may include a linkage reinforcing trace 337a and a linkage reinforcing trace 337b. A line reinforcing trace part 3341c may be connected between the linkage reinforcing trace 337a and the linkage reinforcing trace 337b. The reinforcing trace part 3341c may be a part of the reinforcing trace 3341. The reinforcing trace part 3341c may be connected between the reinforcing trace part 3341a and the reinforcing trace part 3341b. The linkage reinforcing trace 337a may correspond to the linkage trace 327a, the linkage reinforcing trace 337b may correspond to the linkage trace 327b, and the reinforcing trace part 3341c may correspond to the trace part 3241c.
[0443] Figure 44 FIG. 9 is a schematic structural diagram of another circuit board assembly 300 provided by an embodiment of the present application. In some embodiments provided by the present application, the circuit board assembly 300 may further include a preloading pad 351. Along Figure 44 the P-P cross-section shown in FIG. 10 of the circuit board assembly 300 provided by the present application, a cross-sectional view as shown in Figure 45 FIG. 11 can be obtained.
[0444] One side of the preloading pad 351 may abut against the module base 340, and the other side may abut against the reinforcing plate part 331. By providing the preloading pad 351 between the module base 340 and the reinforcing plate part 331, the distance between the reinforcing plate part 331 and the module base 340 can match the dimension of the preloading pad 351 along the optical axis. That is to say, the preloading pad 351 can be used to prevent the reinforcing plate part 331 or the circuit board part 321 from deforming towards the module base 340. Since the image sensor 310 may be disposed on the reinforcing plate part 331 or the circuit board part 321, providing the preloading pad 351 can help reduce the displacement amount of the image sensor 310 towards the module base 340.
[0445] The pre - pressing pad 351 can be disposed in the area of the reinforcing plate portion 331 outside the light - transmitting hole 335. In Figure 44 the illustrated embodiment, the pre - pressing pad 351 can be disposed, for example, in the area between the reinforcing plate protrusion 3311 and the light - transmitting hole 335; the pre - pressing pad 351 can also be disposed, for example, in the area between the reinforcing plate protrusion 3312 and the light - transmitting hole 335; the pre - pressing pad 351 can also be disposed on one side of the circuit - board protrusion 3222 of the circuit - board portion 322 close to the circuit - board portion 322 of the light - transmitting hole 335; the pre - pressing pad 351 can also be disposed on one side of the circuit - board protrusion 3224 of the circuit - board portion 322 close to the circuit - board portion 322 of the light - transmitting hole 335.
[0446] Figure 46 FIG. is a schematic structural diagram of another circuit - board assembly 300 provided by an embodiment of the present application. In some embodiments provided by the present application, the circuit - board assembly 300 may further include a pre - pressing pad 352. Along Figure 46 observing the circuit - board assembly 300 provided by the present application along the Q - Q cross - section shown, a cross - sectional view as shown can be obtained. Figure 47 FIG. is also shown. Figure 47 The assembly relationship between the circuit - board assembly 300 and the camera bracket 210 is also shown.
[0447] One side of the pre - pressing pad 352 can abut against the circuit - board portion 321, and the other side can abut against the camera bracket 210. In one embodiment, the pre - pressing pad 352 can abut against the bearing portion 211 of the camera bracket 210. By disposing the pre - pressing pad 352 between the circuit - board portion 321 and the camera bracket 210, the distance between the circuit - board portion 321 and the camera bracket 210 can match the dimension of the pre - pressing pad 352 along the optical axis. That is to say, the pre - pressing pad 352 can be used to prevent the reinforcing plate portion 331 or the circuit - board portion 321 from deforming towards the camera bracket 210. Since the image sensor 310 can be disposed on the reinforcing plate portion 331 or the circuit - board portion 321, disposing the pre - pressing pad 352 can help reduce the displacement amount of the image sensor 310 towards the camera bracket 210.
[0448] The pre - pressing pad 352 can be disposed in the area of the circuit - board portion 321 outside the light - transmitting hole 325. In Figure 45 the illustrated embodiment, the pre - pressing pad 352 can be disposed, for example, on the circuit - board protrusion 3211 or the circuit - board protrusion 3212 of the circuit - board portion 321; the pre - pressing pad 352 can also be disposed at the corner 1 or the corner 3 of the circuit - board portion 321, where the corner 1 and the corner 3 can be the corners of the circuit - board portion 321 where the SMA - wire movable brackets are not provided.
[0449] Figure 48 FIG. is a schematic structural diagram of another circuit - board assembly 300 provided by an embodiment of the present application.
[0450] In some embodiments provided by the present application, the circuit board assembly 300 may further include a wire protection bracket 353. The wire protection bracket 353 may be annular. The outer periphery of the wire protection bracket 353 may be fixed to the circuit board portion 322. The projection area of the wire protection bracket 353 on the circuit board 320 may intersect with the circuit board portion 321. That is to say, the projection area of the wire protection bracket 353 on the circuit board 320 may cover the spaced space between the circuit board portion 321 and the circuit board portion 322. The wire protection bracket 353 may be in a lid shape and cover a plurality of traces 324. In some embodiments, the wire protection bracket 353 may be located within the space formed by surrounding the SMA wires 311, SMA wires 312, SMA wires 313, and SMA wires 314.
[0451] Since the wire protection bracket 353 covers a plurality of traces 324, when the SMA wires elongate and relax due to elastic recovery, the wire protection bracket 353 can prevent the SMA wires from falling into the gaps between the plurality of traces 324, thereby facilitating reducing the risk of the SMA wires being pinched off by the plurality of traces 324.
[0452] In a possible case, the wire protection bracket 353 may be made of a conductive material. The wire protection bracket 353 may be located between the SMA wires and the image sensor 310, so the wire protection bracket 353 can facilitate shielding the signals generated by the SMA wires and reducing the signal interference of the SMA wires on the image sensor 310.
[0453] The wire protection bracket 353 may have a movable bracket receiving cavity 3531. Figure 41 and Figure 48 , the SMA wire movable bracket 317 may extend from the circuit board portion 321 to the circuit board portion 322. Since the wire protection bracket 353 can cover the space between the circuit board portion 321 and the circuit board portion 322, the wire protection bracket 353 can cover a part of the SMA wire movable bracket 317. To prevent interference between the wire protection bracket 353 and the SMA wire movable bracket 317, the side of the wire protection bracket 353 facing the circuit board 320 may have a movable bracket receiving cavity 3531, and the movable bracket receiving cavity 3531 may be used to accommodate the SMA wire movable bracket 317.
[0454] In Figure 48 the illustrated embodiment, the movable bracket receiving cavity 3531 may also be used to accommodate the SMA wire movable bracket 3110. The side of the wire protection bracket 353 facing the circuit board 320 may also have a movable bracket receiving cavity 3532. The movable bracket receiving cavity 3532 may be used to accommodate the SMA wire movable bracket 318 and the SMA wire movable bracket 319.
[0455] In one embodiment, on the side of the wire protection bracket 353 facing the circuit board 320, there may also be a fixed bracket accommodation cavity 3533 and a fixed bracket accommodation cavity 3534. The fixed bracket accommodation cavity 3533 can be used to accommodate the SMA wire fixed bracket 315, and the fixed bracket accommodation cavity 3534 can be used to accommodate the SMA wire fixed bracket 316.
[0456] Figure 49 It is a schematic structural diagram of another circuit board assembly 300 provided by an embodiment of the present application. In some embodiments provided by the present application, the circuit board assembly 300 may further include a preloading pad 354. Figure 50 is Figure 49 the exploded view of the circuit board assembly 300 shown. Along Figure 49 the R-R cross-section shown to observe the circuit board assembly 300 provided by the present application, a cross-sectional view as shown in Figure 51 or Figure 52 can be obtained.
[0457] One side of the preloading pad 354 can abut against the circuit board portion 321, and the other side can abut against the wire protection bracket 353. By arranging the preloading pad 354 between the circuit board portion 321 and the wire protection bracket 353, the distance between the circuit board portion 321 and the wire protection bracket 353 can match the dimension of the preloading pad 354 along the optical axis. That is to say, the preloading pad 354 can be used to prevent the circuit board portion 321 from deforming towards the wire protection bracket 353. Since the image sensor 310 can be disposed on the reinforcement plate portion 331 or the circuit board portion 321, arranging the preloading pad 354 can help reduce the displacement amount of the image sensor 310 towards the wire protection bracket 353. The specific setting position of the preloading pad 354 can refer to the embodiment of the preloading pad 352.
[0458] Compared with Figure 51 the circuit board assembly 300 shown, Figure 52 the circuit board assembly 300 shown may further include a preloading pad 351, and the preloading pad 351 is disposed between the reinforcement plate 330 and the module base 340. The embodiment of the preloading pad 351 can refer to the embodiments shown in Figure 44 and Figure 45 .
[0459] In some embodiments provided by the present application, the camera module 200 may further include a filter 361, as shown in Figure 53 . Along Figure 53 the S-S cross-section shown to observe the circuit board assembly 300 provided by the present application, a cross-sectional view as shown in Figure 54 can be obtained. The filter 361 can be used to filter light of a specific frequency. In one embodiment, the filter 361 can be used to filter infrared light.
[0460] In some embodiments, the filter 361 can be fixed to the circuit board 320 through the filter holder 362. The filter holder 362 can include a light-transmitting hole 363. Combining Figure 4 and Figure 54 , the light from the lens 221 can enter the light-transmitting hole 325 of the circuit board 320 after passing through the light-transmitting hole 363. The light-transmitting hole 363 can be disposed opposite to the light-transmitting hole 325. Along the optical axis, the projection area of the light-transmitting hole 363 can mostly overlap with the projection area of the light-transmitting hole 325. One side of the filter holder 362 can be fixed to the circuit board portion 321. The filter holder 362 can surround the outer periphery of the light-transmitting hole 325 of the circuit board portion 321.
[0461] In a possible case, the filter holder 362 includes a filter fixing member 364. The filter fixing member 364 can be annular. The outer periphery of the filter fixing member 364 can be embedded in the filter holder 362. When observed along the optical axis, the filter fixing member 364 can extend from the filter holder 362 toward the optical axis and extend into the light-transmitting hole 363. When observed along the optical axis, the projection area of the inner periphery of the filter fixing member 364 can be located within the projection area of the light-transmitting hole 363. The area of the filter fixing member 364 located outside the filter holder 362 can be fixedly connected to the filter 361. The spaced space between the filter fixing member 364 and the circuit board portion 321 can be used to accommodate the lead 326 of the image sensor 310. In Figure 54 the illustrated embodiment, the filter 361 can be fixed to the side of the filter fixing member 364 away from the image sensor 310. The filter 361 can be accommodated in the light-transmitting hole 363. The outer diameter of the filter 361 can be smaller than the inner diameter of the light-transmitting hole 363. This is beneficial to reducing the occupied space of the light-transmitting hole in the direction of the optical axis. In a possible scenario, the dimension of the filter 361 along the optical axis can be smaller than or equal to the dimension of the light-transmitting hole 363 along the optical axis.
[0462] In another possible case, the filter 361 can be fixed to the side of the filter holder 362 away from the circuit board 320. The filter 361 can cover the light-transmitting hole 363. The area of the filter holder 362 located outside the light-transmitting hole 363 can be fixedly connected to the filter 361. In this embodiment, on the one hand, the filter 361 may occupy a certain space in the direction of the optical axis; on the other hand, when dust is deposited on the filter 361, since the distance between the filter 361 and the image sensor 310 is relatively far, the image captured by the image sensor 310 is relatively less affected by the dust.
[0463] In another possible scenario, through the molding on chip (MOC) process, the leads 326 of the image sensor 310 can be encapsulated within the filter holder 362. This is beneficial for reducing the size of the filter holder 362 in the direction perpendicular to the optical axis and also for improving the mechanical stability of the leads 326 of the image sensor 310.
[0464] This application provides a camera module and an electronic device. By configuring a pop-up component that applies the piezoelectric principle, the lens groups 223 and 224 of the camera module can be popped out integrally; by configuring a focusing component that applies the piezoelectric principle, the distance between the lens groups 223 and 224 can be adjusted. The pop-up component and the focusing component that apply the piezoelectric principle can relatively easily control the displacement of the lens groups 223 and 224 deviating from the optical axis and have a relatively small occupied space, enabling the camera module to have excellent shooting performance and a relatively small occupied space.
[0465] As described above, the above are only specific embodiments of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed in this application can easily think of changes or substitutions, which should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
