Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. The embodiments of the application may be suitably combined with each other.

Referring to fig. 1, an electronic device 1000 is provided in an embodiment of the application. The electronic device 1000 includes, but is not limited to, a cell phone, telephone, television, tablet, cell phone, camera, personal computer, notebook, vehicle mounted device, wearable device, personal digital assistant (Personal Digital Assistant, PDA), electronic book reader, laptop portable computer, desktop computer, set-top box, etc. The wearable device is a portable electronic device 1000 that is worn directly with or integrated into a user's clothing or accessories. The embodiment of the application is specifically described by taking the electronic device 1000 as a mobile phone.

Referring to fig. 1 and 2, an electronic device 1000 includes a display 200, a housing 300, and a camera module 100.

The display screen 200 is generally rectangular. The display screen 200 is a module for the electronic device 1000 to display an image. The display 200 is disposed on the front surface of the electronic device 1000, and the front surface of the electronic device 1000 is also the surface that the user faces when using the electronic device 1000 normally. Display 200 includes, but is not limited to, a flexible display, a rigid display, a flexible display, a stretchable display, and the like. The types of display screen 200 include, but are not limited to, liquid crystal display (Liquid Crystal Display, LCD), light Emitting Diode (Light Emitting Diode, LED) display, organic Light-Emitting Diode (OLED) display, and the like. From the shape division of the display screen, the display screen 200 includes, but is not limited to, a flat plate shape or a 2.5D curved surface or a 3D curved surface, etc.

Referring to fig. 2, the housing 300 includes a middle frame 301 and a rear cover 304, and the display screen 200 and the rear cover 304 are respectively enclosed on two opposite sides of the middle frame 301. The middle frame 301 includes a frame 302 and a middle plate 303 disposed in the frame 302. The frame 302 is disposed on a side of the electronic device 1000. The frame 302 is circumferentially connected to the display screen 200. When the electronic device 1000 is substantially rectangular, the frame 302 includes four sides to be disposed on four sides of the electronic device 1000 respectively. The middle plate 303 is disposed opposite to the display screen 200 in the thickness direction of the electronic apparatus 1000. The middle plate 303 includes an aluminum alloy injection molded body, a plastic injection molded body, etc. disposed in the frame 302, and the middle plate 303 forms a chamber for accommodating a main board, a battery, and various electronic components, so that the main board, the battery, and the various electronic components can be orderly mounted in the electronic device 1000. It will be appreciated that the screen of the display screen 200 of the present application occupies a relatively large area, and the front projection of the display screen 200 in the thickness direction may completely cover the middle plate 303 or cover 80-100% of the middle plate 303. The area of the display screen 200 where the image is displayed accounts for 85-100% of the area of the entire front surface of the display screen 200.

Referring to fig. 1 and 2, a rear cover 304 is covered on a side of the frame 302 facing away from the display screen 200. In this embodiment, the frame 302 and the rear cover 304 are two independent parts. In other embodiments, bezel 302 is integrally formed with rear cover 304. The materials of the frame 302 and the rear cover 304 are not particularly limited in the present application, for example, the materials of the frame 302 and the rear cover 304 include, but are not limited to, at least one of plastics, metals, ceramics, glass, etc. The rear cover 304, the middle frame 301 and the display screen 200 enclose a containing space 401, and at least a portion of the camera module 100 is disposed in the containing space 401.

Referring to fig. 2, the rear cover 304 has a mounting hole 402 communicating with the accommodating space 401. Specifically, the mounting hole 402 penetrates the rear cover 304 in the thickness direction of the electronic apparatus 1000. A part of the camera module 100 is installed in the accommodating space 401, and another part of the camera module 100 is installed in the mounting hole 402.

The camera module 100 provided by the application is a camera which can extend and retract relative to the rear cover 304. For example, fig. 1 is a schematic structural diagram of the camera module 100 in a retracted state. Fig. 3 is a schematic structural view of the camera module 100 in an extended state. The camera module 100 may also be referred to as a retractable camera module, a pop-up camera module, and the like.

The specific structure of the camera module 100 is illustrated in the following drawings.

Referring to fig. 4, the camera module 100 at least includes a lens assembly 2, a photosensitive assembly 3 and a first driving module 51.

Referring to fig. 4, the lens assembly 2 includes a lens barrel 221 and a lens group 222 disposed in the lens barrel 221, wherein the lens group 222 includes a plurality of lenses. Optionally, the lens assembly 2 further includes a light-transmitting cover plate 223, where the light-transmitting cover plate 223 covers an end of the lens barrel 332 facing the object to be photographed, so as to seal and protect the lens group 222.

The photosensitive assembly 3 is disposed opposite the lens assembly 2 along an optical axis Z of the lens assembly 2. The optical axis of the lens assembly 2 is also the optical axis of the lens group 222, that is, the axis passing through the geometric center point of the lens group 222 along the arrangement direction of the plurality of lenses. For convenience of description, a side of the lens assembly 2 facing the object is taken as an object side, and a side of the lens assembly 2 facing the photosensitive assembly 3 is taken as an image side. The subsequent optical axis directions include a direction along the optical axis toward the image side (in the present application, the optical axis image side direction is abbreviated as the-Z direction in fig. 4), and a direction along the optical axis toward the object side (in the present application, the optical axis object side direction is abbreviated as the +z direction in fig. 4).

The photosensitive assembly 3 includes at least a sensor, such as an image sensor, for converting an optical signal into an image signal. The image sensor and the lens group 222 are arranged along the optical axis direction to receive the light signal transmitted through the lens group 222.

Referring to fig. 4 and 5, the first driving module 51 includes a power unit 515 and a movable member 514, wherein the power unit 515 and the movable member 514 may be directly connected or interact with each other through magnetic force. The movable piece 514 is connected with the lens assembly 2, and the connection mode includes, but is not limited to, fixed connection or movable connection, wherein the fixed connection includes, but is not limited to, welding, screwing, clamping connection, bonding and the like; the movable connection includes, but is not limited to, abutment of the movable piece 514 with the lens assembly 2 in a direction, which is not limited to the optical axis image side direction (-Z axis) or the optical axis object side direction (+z axis), or the like.

The power unit 515 is configured to drive the movable member 514 to move linearly, and the linear movement direction may be along an optical axis image side direction (-Z axis), an optical axis object side direction (+z axis), or an oblique direction intersecting the optical axis (as long as there is a certain movement component in the optical axis direction), so as to drive the lens assembly 2 to move along the optical axis Z relative to the photosensitive assembly 3. Optionally, the power unit 515 drives the movable member 514 to move unidirectionally in an optical axis image-side direction (-Z axis), unidirectionally in an optical axis object-side direction (+z axis), or to reciprocate in the optical axis image-side direction (-Z axis) and in the optical axis object-side direction (+z axis). When the power unit 515 drives the movable member 514 to linearly move, the movable member 514 drives the lens assembly 2 to move along the optical axis Z toward or away from the photosensitive assembly 3, so that the distance between the lens assembly 2 and the photosensitive assembly 3 is changed, thereby realizing optical focusing of the camera module 100 and improving the imaging quality of the camera module 100.

It should be noted that, the movable member 514 performs a linear motion, the linear motion process is simple, and the power generated by the motion of the movable member 514 can be efficiently transmitted to the lens assembly 2, and the device has the characteristics of simple driving structure, high driving force transmission efficiency, and the like.

Alternatively, the present application defines a position where the lens assembly 2 approaches to the minimum distance from the photosensitive assembly 3 as a retracted position, where the lens assembly 2 is in a retracted state (may also be referred to as a folded state, a stored state, a retracted state, etc.), and defines a position where the lens assembly 2 is away from the maximum distance from the photosensitive assembly 3 as an extended position, where the lens assembly 2 is in an extended state (may also be referred to as an ejected state, an extended state, etc.), where the camera module 100 is in an operating state. Of course, the lens assembly 2 may also stay in a position between the extended position and the retracted position, i.e. the lens assembly 2 may remain in its position during extension while the extension part progresses, which also serves as an intermediate extended position in which the camera module 100 operates. The number of the intermediate extended positions is not particularly limited, for example, one intermediate extended position, three intermediate extended positions, etc., so as to implement that the camera module 100 operates in different working states under a plurality of focal lengths.

When the lens assembly 2 is in the retracted state, the distance between the lens assembly 2 and the photosensitive assembly 3 in the optical axis Z direction is small, and the overall length of the camera module 100 is small, which is beneficial for the camera module 100 to be stored in the electronic device 1000 with extremely limited space. When the lens assembly 2 is in the extending state, the total length of the optical system formed by the lens assembly 2 and the photosensitive assembly 3 is increased, a longer focal length can be realized during optical design, and the longer focal length is beneficial to improving the performance of the optical system and the optical blurring effect beyond the depth of field, wherein the optical blurring effect is more real and surprise than the algorithm blurring effect, and because the optical blurring effect is completely different according to the distance of an actual scene, errors can not occur due to the complexity of the scene, the embodiment of the application increases the focal length by designing the lens assembly 2 to be far away from the photosensitive assembly 3, so as to realize the imaging effect with higher definition and reality.

According to the camera module 100 provided by the embodiment of the application, the movable piece 514 is driven to move along the straight line by designing the power unit 515 of the first driving module 51, the movable piece 514 drives the lens assembly 2 to move relative to the photosensitive assembly 3, the distance between the lens assembly 2 and the photosensitive assembly 3 is changed, and optical focusing is realized, so that the imaging effect with higher definition and higher reality is realized, and the imaging quality of the camera module 100 is improved.

It is understood that specific types of camera modules 100 include, but are not limited to, one of a master camera, a wide angle camera, a tele camera, a periscope tele camera, a macro camera, etc., or cameras that integrate multiple functions as described above.

Referring to fig. 1 to 4 in combination, when the camera module 100 is mounted in the mounting hole 402 and the accommodating space 401 for the whole electronic device 1000, at least a portion of the lens assembly 2 is disposed in the mounting hole 402, and the photosensitive assembly 3 is mounted in the accommodating space 401. The retracted state of the lens assembly 2 may be completely accommodated in the mounting hole 402, for example, the cover plate on the object side of the lens assembly 2 is flush with the outer surface of the rear cover 304 or the cover plate on the object side of the lens assembly 2 is lower than the outer surface of the rear cover 304. Alternatively, the retracted state of the lens assembly 2 has a small amount of protrusions protruding from the outer surface of the rear cover 304 to form a high distinction between the camera module 100 and the rear cover 304 without forming excessively protruding protrusions on the rear cover 304. The lens assembly 2 is extended towards the side far away from the display screen 200 under the action of the first driving module 51, so that the lens assembly 2 gradually extends out of the mounting hole 402 to a proper position; and/or the lens assembly 2 is retracted toward a side close to the display screen 200 by the first driving module 51. It should be noted that, the first driving module 51 is used to drive the lens assembly 2 to extend in a single pass, retract in a single pass, or reciprocate in two passes.

In the general technology, since the thickness of the electronic device 1000 limits the overall length of the camera module, when the overall length of the camera module is limited, the photosensitive area of the camera is limited, so that the photosensitive area of the camera is relatively small, and the imaging definition, fidelity and the like of the camera are affected to a certain extent. Moreover, the existing camera design is very sensitive to the module height, and an excessively high module height can form an abrupt bulge on the rear cover 304 of the electronic device 1000, so that the touch feel and the overall appearance of the rear cover 304 of the electronic device 1000 are affected.

According to the application, the lens component 2 of the camera module 100 is designed to extend from one side of the rear cover 304 away from the display screen 200, and the length of the lens component 2 in the extending state is the module length of the camera module 100 in normal operation, that is, the module length of the camera module 100 is not limited by the thickness of the electronic device 1000 any more, so that compatibility of relatively larger module length of the camera module 100 and relatively smaller thickness of the electronic device 1000 is realized. Because the camera module 100 has a relatively large length in the extended state, the imaging size of the photosensitive assembly 3 of the camera module 100 can be relatively large (i.e. the outsole is photosensitive), so that the lighting area of the camera module 100 is relatively large, and further, an image with better quality is obtained. In the present embodiment, the surface on which the photosensitive element 3 is located is the surface on which the electronic device 1000 is long and wide, and thus the electronic device 1000 itself has a large carrying space on the surface on which the photosensitive element 3 is located, and therefore the electronic device 1000 also has a potential of housing the photosensitive element 3 having a large area. When the lens assembly 2 is in the retracted state, the lens assembly 2 is retracted into the accommodating space 401, and at this time, the camera module 100 will not form a convex protrusion on the rear cover 304, which is beneficial to the good appearance of the electronic device 1000 and the touch feeling of the user's hand touch, and improves the portability of the electronic device 1000.

The number of the retractable camera modules 100 in the electronic device 1000 is not particularly limited. For example, the form of the electronic device 1000 in which the tele camera may be disposed is a retractable form provided by the embodiment of the present application, and the form of the tele camera and the macro camera may also be a retractable form provided by the embodiment of the present application.

The package structures of the lens assembly 2 and the photosensitive assembly 3 provided by the application include, but are not limited to, the following embodiments.

Optionally, referring to fig. 4 and 5, the camera module 100 further includes a housing 1. The housing 1 is a housing structure of the camera module 100. Referring to fig. 2, the housing 1 is fixedly installed in the accommodating space 401, and one end of the housing 1 near the object side is installed in the installation hole 402.

Referring to fig. 4, the housing 1 includes a top plate 12 and a bottom plate 11 disposed opposite to each other, and a peripheral plate 13 surrounding between the top plate 12 and the bottom plate 11. Wherein the top plate 12 and the bottom plate 11 are arranged along the optical axis Z. The top plate 12, the bottom plate 11, and the peripheral plate 13 enclose the housing chamber 1a. It will be appreciated that the top plate 12, bottom plate 11 and peripheral side plate 13 are merely azimuthally divided. The top plate 12 may be integrally formed with a portion of the peripheral side plate 13 and the bottom plate 11 may be integrally formed with another portion of the peripheral side plate 13.

Referring to fig. 4, at least a portion of the lens assembly 2 is disposed in the housing 1. The top plate 12 has a telescopic hole 1b. Optionally, the movable member 514 is disposed in the housing 1. The movable member 514 is used for driving the lens assembly 2 to at least partially extend out of the housing 1 or retract into the housing 1 through the telescopic hole 1b. The photosensitive assembly 3 is arranged on the bottom plate 11.

The bearing frame 21 is located between the top plate 12 and the bottom plate 11, and is disposed opposite to both the top plate 12 and the bottom plate 11. The lens module 22 is disposed on a side of the carrier 21 away from the base plate 11. The carrier 21 is connected to the movable member 514. The movable piece 514 is driven by the power unit 515 to move along a straight line, so as to drive the bearing frame 21 to move, and further drive the lens assembly 2 to stretch and retract.

Referring to fig. 8 and 9, the camera module 100 further includes an adjusting component 4. The adjustment assembly 4 includes at least one of a focusing module 41, an optical anti-shake module 42.

The adjusting component 4 is arranged on the periphery of the lens component 2 and on the bearing frame 21. The adjustment assembly 4 expands and contracts with the lens assembly 2.

The adjustment housing 40 is provided with a first through hole 40a, and the light-transmitting cover plate 223 covers the first through hole 40a. The lens assembly 2 is disposed in the adjustment housing 40 and disposed corresponding to the first through hole 40a. The focusing module 41 and the optical anti-shake module 42 are disposed on the periphery of the lens assembly 2.

Referring to fig. 9, the focusing module 41 at least includes a first carrier 411, a magnetic coil assembly 412 disposed on the first carrier 411, and a plurality of first magnetic assemblies 413 disposed on the first carrier 411 and surrounding a periphery of the magnetic coil assembly 412. The first carrier 411, the plurality of first magnetic assemblies 413, and the adjustment housing 40 are fixed relative to one another. The electromagnetic coil assembly 412 has a second through hole 412a. The second through hole 412a of the electromagnetic coil assembly 412 corresponds to and is conducted through the first through hole 40a of the adjustment case 40. The electromagnetic coil assembly 412 surrounds the circumference of the lens assembly 2. The electromagnetic coil assembly 412 is connected to the lens assembly 2. The plurality of first magnetic assemblies 413 are used for driving the electromagnetic coil assembly 412 to drive the lens assembly 2 to move along the optical axis Z direction. Specifically, electromagnetic coil assembly 412 receives the electrical signal and generates a first magnetic force with first magnetic assembly 413. Since the first magnetic assembly 413 is relatively fixed to the carrier 21. The electromagnetic coil assembly 412 is capable of moving along the optical axis direction, so that the first magnetic force drives the electromagnetic coil assembly 412 to move along the optical axis image side or the optical axis object side direction, and further drives the lens assembly 2 to perform auto-focus adjustment along the optical axis image side or the optical axis object side.

It can be appreciated that the amount of movement of the focusing module 41 in the optical axis Z direction for the lens assembly 2 is much smaller than the amount of movement of the first driving module 51 to drive the lens assembly 2. The focusing module 41 is different from the first driving module 51 in that the former is fine-tuned to an optimal focal length in a focal length range at the time of imaging, and the latter is to increase a distance between the lens assembly 2 and the photosensitive assembly 3 from a very small pitch to the focal length range of the lens assembly 2.

Referring to fig. 9, the optical anti-shake module 42 includes a second carrier 421, a plurality of guiding portions 422, and a second magnetic component 423. The second carrier 421 is disposed opposite at least a portion of the first carrier 411. The second carrier 421 has a third through hole 421a. The third through hole 421a of the second carrier 421 corresponds to and is in communication with the second through hole 412a of the electromagnetic coil assembly 412. The second carrier 421 is disposed around the periphery of the lens assembly 2. The second carrier 421 is connected to the lens assembly 2. The first magnetic assemblies 413 are further used for driving the second magnetic assemblies 423 to drive the lens assembly 2 to move along a direction perpendicular to the optical axis. Specifically, a plurality of first magnetic assemblies 413 are disposed around the circumferential side of the second magnetic assembly 423. The second magnetic assembly 423 receives the electrical signal and generates a second magnetic force with the first magnetic assembly 413. Since the first magnetic assembly 413 is relatively fixed to the carrier 21. The second magnetic component 423 can move on a plane perpendicular to the optical axis direction, so the second magnetic force drives the second magnetic component 423 to drive the second carrier 421 and the lens component 2 to move along the direction perpendicular to the optical axis Z, so as to compensate the displacement offset caused by shake in the shooting process, thereby realizing the optical anti-shake function of the camera module 100.

Further, at least part of the guide 422 is in rolling connection with the first carrier 411. The guide portion 422 includes a rail 4221 and a rolling portion 4222 rollably connected to the rail 4221. The rail 4221 is provided on the second carrier 421. The rolling portion 4222 includes, but is not limited to, a ball. The rolling portion 4222 is in rolling connection with the first carrier 411 to improve movement smoothness during the relative movement of the first carrier 411 and the second carrier 421.

The second carrier 421 has a plurality of corners 4211. The number of corner portions 421 in fig. 9 is 4. The number of the guide portions 422 is four. Each guide 422 is provided at one corner 421. Of course, in other embodiments, the number of corners 4211 is three, five, etc. By providing the guide rail 4221 and the rolling portion 4222 at each of the four corner portions 421, the smoothness of movement of the second carrier 421 in a plane perpendicular to the optical axis Z direction is improved. Since the lens assembly 2 is cylindrical. The second carrier 421 is rectangular, and the guide portion 422 is disposed at the corner 4211 to fully utilize the space on the corner 4211 of the second carrier 421, thereby further reducing the volume of the entire lens assembly 2 and the adjustment assembly 4.

Alternatively, first magnetic component 413 includes, but is not limited to, a permanent magnet, a solenoid, or the like. Optionally, the number of the first magnetic assemblies 413 is 4, and the first magnetic assemblies are respectively disposed at four corners of the first carrier 411, so as to fully utilize the space at the corners of the first carrier 411, and further reduce the overall volume of the focusing module 41.

The second magnetic assembly 423 includes, but is not limited to, a permanent magnet, a solenoid, and the like. Optionally, the second magnetic component 423 is an electromagnetic coil, and an axial direction of the hole of the second magnetic component 423 is an optical axis direction. At least one second magnetic component 423 is disposed corresponding to one first magnetic component 413, i.e., the second magnetic component 423 is also located at the corner 4211 of the second carrier 421, so that the space on the corner 4211 of the second carrier 421 is further effectively utilized to reduce the overall volume of the optical anti-shake module 42.

The guide rail 4221 of the guide 422 in fig. 9 is disposed in two diagonal directions. The rolling portion 4222 is movable in a diagonal direction along the guide rail 4221. That is, the second carrier 421 can drive the lens assembly 2 to move along two diagonal directions, and the two diagonal movements are combined together, so that any direction movement in the X-Y plane can be realized, thereby realizing the function of optical anti-shake calibration and shake. Of course, in other embodiments, the guide rail 4221 of the guide portion 422 may be provided along the X-axis direction or the Y-axis direction. Alternatively, other directions intersecting the X-axis direction and the Y-axis direction are provided.

The controller of the electronic apparatus 1000 forms an electric signal compensating for the displacement variation according to the displacement variation generated during photographing. The first magnetic component 413 and/or the second magnetic component 423 can be correspondingly displaced in the X-axis direction and the Y-axis direction after receiving the electrical signal, so as to drive the lens component 2 to move in the X-Y plane, including but not limited to moving in the X-axis forward direction, moving in the X-axis reverse direction, moving in the Y-axis forward direction, moving in the Y-axis reverse direction, moving in the diagonal direction, and the like. The present embodiment can implement optical anti-shake compensation of the lens assembly 2 in the X-Y plane, thereby improving the imaging quality of the camera module 100.

In other embodiments, the optical anti-shake module 42 may also be formed of a deformable structure deformable in the X-axis direction and the Y-axis direction, for example, a deformable structure made of an electrostrictive material, specifically, for example, a shape memory alloy, a piezoelectric ceramic, a ferroelectric polymer, or the like. The controller of the electronic apparatus 1000 forms an electric signal compensating for the displacement variation according to the displacement variation generated during photographing. The deformation structure receives the electric signals and then generates corresponding deformation in the X-axis direction and the Y-axis direction, and the deformation structure is connected with the lens assembly 2 to drive the lens assembly 2 to move in the X-Y plane so as to perform optical anti-shake compensation, thereby improving the imaging quality of the camera module 100.

In the adjusting component 4 provided in the second embodiment, referring to fig. 10, the adjusting component 4 is disposed on a peripheral side of the photosensitive component 3 and is fixed relative to the photosensitive component 3. Optionally, the adjusting component 4 is disposed on the bottom plate 11 and is fixed relative to the photosensitive component 3. Specifically, the adjusting component 4 is connected to the periphery of the photosensitive component 3 in a surrounding manner, and is used for adjusting the photosensitive component 3 to move along the optical axis Z direction relative to the lens component 2 so as to realize automatic focusing, and is also used for adjusting the photosensitive component 3 to move along a plane perpendicular to the optical axis Z direction relative to the lens component 2 so as to realize an optical anti-shake function. By arranging the adjusting component 4 in the accommodating cavity 1a, the adjusting component does not need to extend out together with the lens component 2, the structural volume required to extend out can be reduced, the size and the weight of the structure required to extend out are further reduced, the weight required to be driven by the first driving module 51 is reduced, electric energy is saved, and the service life of the electronic equipment 1000 is prolonged. When the adjustment assembly 4 does not extend with the lens assembly 2, the lens assembly 2 may be rounded in shape to reduce the volume of structure required to extend. The specific structure of the adjusting assembly 4 in the present embodiment may refer to the structure in fig. 9.

In the other embodiments of the adjusting assembly 4, the focusing module 41 and the optical anti-shake module 42 are separately disposed on the photosensitive assembly 3 and the lens assembly 2, for example, the focusing module 41 is disposed on the peripheral side of the photosensitive assembly 3, and the optical anti-shake module 42 is disposed on the peripheral side of the lens assembly 2; or, the focusing module 41 is disposed on the peripheral side of the lens assembly 2, and the optical anti-shake module 42 is disposed on the peripheral side of the photosensitive assembly 3, so that the flexibility of the camera module 100 is improved by the flexible design, and the suitable setting mode of the adjusting assembly 4 is adaptively selected based on different requirements.

Referring to fig. 11, the carrier 21 is substantially square, and the carrier 21 has a hollow structure, and a hollow channel in the middle of the carrier 21 provides a light conducting channel between the lens assembly 2 and the photosensitive assembly 3. Four corners of the carrier 21 extend towards the hollow structure to form four extension portions 212, the four extension portions 212 extend towards the center of the carrier 21, and the bottom of the lens assembly 2 is provided with a groove portion 213 corresponding to the four extension portions 212. Each extension 212 is disposed in one of the grooves 213 to accurately align the lens assembly 2 with the carrier 21 without moving in the X-Y plane.

By arranging the bearing frame 21, the first driving module 51 moves through driving the bearing frame 21, the bearing frame 21 is fixedly connected with the lens module 22, and the bearing frame 21 drives the lens module 22 to move, so that a structure directly connected with the first driving module 51 is not required to be arranged on the lens module 22, but a structure connected with the first driving module 51 is arranged on the bearing frame 213. In the present application, since the lens module 22 is synchronized with the movement of the carrier 21, it is also assumed that the lens module 22 is synchronously moved in the same direction when the carrier 21 is driven to move in a certain direction.

Of course, in other embodiments, the carrier 21 may not be provided, and the first driving module 51 is directly connected to the lens module 22 to drive the lens module 22 to extend in a single pass, retract in a single pass, or reciprocate.

The arrangement between the first driving module 51 and the lens assembly 2 is not particularly limited. The following exemplifies the arrangement relationship between the first driving module 51 and the lens assembly 2 with reference to the drawings.

Optionally, referring to fig. 4 and 5, the front projection of the first driving module 51 in the first direction at least partially coincides with the front projection of the lens assembly 2 in the first direction, wherein the first direction is perpendicular to the optical axis Z direction. For convenience of description, a plane perpendicular to the optical axis Z is defined as an X-Y plane. The first direction may be any direction within the X-Y plane. For example, the first direction is the X direction in fig. 4.

The front projection of the first driving module 51 in the first direction and the front projection of the lens assembly 2 in the first direction are at least partially overlapped, so that the heights of the first driving module 51 and the lens assembly 2 in the optical axis Z direction are at least partially overlapped, and the sizes of the first driving module 51 and the lens assembly 2 in the optical axis Z direction are reduced.

Specifically, the first driving module 51 and the lens assembly 2 are arranged along a direction non-parallel to the optical axis Z. That is, the arrangement direction of the first driving module 51 and the lens assembly 2 may be any one direction of the X-Y plane, or may be a direction inclined with respect to the X-Y plane (a direction intersecting the X-Y plane and not parallel to the optical axis Z direction).

In an embodiment, referring to fig. 4, the first driving module 51 and the lens assembly 2 may be arranged in an X-Y plane. Specifically, the first driving module 51 is coplanar with the lens assembly 2 in the retracted state in the X-Y plane, and may have a smaller drop in the X-Y plane. The lens assembly 2 and the first driving module 51 are arranged side by side in the X-Y plane, which is beneficial to reducing the dimension of the camera module 100 along the optical axis Z direction and realizing the optical design of the outsole, the large aperture and the long focal length of the rear camera.

In another embodiment, the first driving module 51 is arranged with the lens assembly 2 in a direction inclined with respect to the X-Y plane.

In this embodiment, the first driving module 51 and the lens assembly 2 are arranged along the direction intersecting the optical axis Z, instead of being stacked along the optical axis Z, so that the stacking size of the first driving module 51 and the lens assembly 2 along the optical axis Z can be reduced, and the stacking size of the camera module 100 in the thickness direction of the electronic device 1000 is further reduced because the optical axis Z is also the thickness direction of the electronic device 1000, thereby promoting the thinning of the electronic device 1000.

In another aspect, the lens assembly 2 and the photosensitive assembly 3 are integrated, and the first driving module 51 is located on a side surface of the integrated lens assembly 2 and the photosensitive assembly 3, where the side surface is a side where the image side and the object side are removed. It should be noted that, the "image side" herein refers to a pointing side of the object toward the side where the image side of the optical axis is located, the "object side" refers to a pointing side of the object toward the side where the object side of the optical axis is located, and other structures will take the image side and the object side as reference sides, which will not be described in detail.

The positional relationship between the first drive module 51 and the housing case 1 is not particularly limited in the present application. Optionally, the first driving module 51 is disposed in the housing 1.

Referring to fig. 4 and 12, the first driving module 51 has a driving housing 510, and an inner cavity of the driving housing 510 is communicated with the accommodating cavity 1a of the accommodating housing 1. A part of the surface of the driving case 510 and a part of the surface of the housing case 1 are spliced to form a complete surface. For example, referring to fig. 6 and 8, the plate of the driving case 510 facing the object side and the top plate 12 of the housing case 1 are spliced to form a plate of the camera module 100 facing the object side. The plate of the driving shell 510 facing the image side is arranged on the bottom plate 11 of the accommodating shell 1, so that the accommodating shell 1 carries the driving shell 510. The first driving module 51 can be assembled with the lens assembly 2 in the housing 1 after being produced as an independent module, so that the camera module 100 can be at least divided into two independent modules for processing and assembling, thereby avoiding the inconvenience of integral assembly, improving the convenience and efficiency of assembly, and being convenient for replacement when one of the modules is damaged.

For the internal structure of the first driving module 51, please refer to fig. 13, the front projection of the movable member 514 in the first direction at least partially coincides with the front projection of the lens assembly 2 in the first direction. The front projection of power unit 515 in the second direction at least partially overlaps the front projection of moveable member 514 in the second direction, the second direction being perpendicular to the optical axis Z direction, and the second direction intersecting the first direction. The second direction is the direction intersecting the first direction in the X-Y plane. By arranging the movable piece 514, the lens component 2 and the power unit 515 in the X-Y plane side by side, stacking in the Z direction of the optical axis is reduced, the thickness of the camera module 100 is reduced, the size of the camera module 100 along the Z direction of the optical axis is reduced, and the rear camera outsole, the large light-transmitting aperture and the long-focal-length optical design are realized.

Optionally, the second direction is perpendicular to the first direction, e.g. the second direction is the Y-axis direction. By arranging the arrangement direction of the movable piece 514 and the power unit 515 to be perpendicular to the arrangement direction of the movable piece 514 and the lens assembly 2, the movable piece 514, the power unit 515 and the lens assembly 2 are compactly arranged on an X-Y plane, so that the area of the whole camera module 100 in the X-Y plane is further reduced, and the miniaturization of the camera module 100 is promoted.

The overall outer contour of the lens assembly 2 is not particularly limited, and may be circular, square, or the like. An adjusting component (see adjusting component 4 in fig. 8) such as an auto-focusing module 41 and an optical anti-shake module 42 may be disposed on the peripheral side of the lens assembly 2, and the overall outline of the lens assembly 2 after being packaged is rectangular. One of the lens components 2 is along the X-axis direction and the other is along the Y-axis direction. Specifically, the first direction is the X-axis direction, and the second direction is the Y-axis direction. In this way, the movable member 514 and the power unit 515 are arranged beside the side extending in the Y-axis direction of the lens assembly 2, so that the movable member 514, the power unit 515, and the lens assembly 2 are compactly arranged in the X-axis direction and the Y-axis direction, the area occupied by the camera module 100 in the X-Y plane is small, and the stacking size in the optical axis Z direction is small, thereby promoting miniaturization of the camera module 100. Moreover, the power unit 515 acts on the movable member 514 in the second direction, so that the movable member 514 moves linearly in the optical axis Z direction or moves in an inclined direction (for example, the movable member 514 moves along an inclined surface of the inclined slider) and has a movement component in the optical axis Z direction, and thus drives the lens assembly 2 to move in the optical axis Z direction, which converts the driving force in the X-Y plane into the acting force in the optical axis Z direction.

Alternatively, the movable member 514 moves along the optical axis Z under the action of the power unit 515, so that the movable member 514 drives the lens assembly 2 to move along the optical axis Z with high force transmission efficiency.

In the present application, the first drive module 51 may be used to drive the lens assembly 2 back and forth, single pass extension, or single pass retraction.

The specific structure of the first driving module 51 driving the lens assembly 2 to retract in a single pass provided in the first embodiment is illustrated below with reference to the accompanying drawings. During a single retraction of the lens assembly 2 driven by the first driving module 51, the camera module 100 further includes a second driving module 52 (refer to fig. 14). The second driving module 52 cooperates with the first driving module 51 to extend and retract the lens assembly 2.

Referring to fig. 12 and 13, the first driving module 51 further includes a rotating rod 513 and a transmission member 516. The drive case 510 includes a drive frame 511 and a drive cover 512 covering the drive frame 511 along the optical axis Z direction. The power unit 515, the movable member 514, the rotating rod 513, and the transmission member 516 are all disposed in the driving housing 510. The rotation lever 513 is disposed along the optical axis Z direction. Alternatively, opposite ends of the rotation lever 513 are rotatably coupled to the driving cover 512 and the driving frame 511, respectively. The movable member 514 is sleeved on the rotating rod 513 and is in threaded connection with the rotating rod 513.

Alternatively, the rotating rod 513 is a screw, the movable member 514 is a nut, and the internal thread of the movable member 514 is connected with the external thread of the rotating rod 513. The power unit 515 rotates (rotates) by driving the rotation lever 513 to drive the movable member 514 to move along the rotation lever 513 (i.e., the optical axis+z direction or-Z direction movement).

The transmission member 516 is disposed substantially along the second direction (Y-axis direction), and the transmission member 516 is connected between the power unit 515 and the rotating lever 513. In other words, the power unit 515, the transmission member 516, and the rotation lever 513 are sequentially disposed along the Y-axis direction, so as to reduce the area occupied by the whole module in the X-axis direction. The power unit 515 is used for driving the rotating rod 513 to rotate through the transmission member 516, and the movable member 514 moves along the optical axis Z along with the rotation of the rotating rod 513. The driving member 516 includes, but is not limited to, a gear set, a belt-roller combination, a pull cord, etc.

Optionally, the transmission member 516 includes a first gear 5161, a second gear 5162, and a third gear 5163 sequentially meshed with each other. The number of the second gears 5162 is at least one. First gear 5161 is coaxially coupled to a rotational axis of power unit 515. The third gear 5163 is coaxially connected to the rotation lever 513.

Wherein power unit 515 is a motor, and the rotation axis of power unit 515 is disposed along the Z-axis direction of the optical axis or along the Y-axis direction. When the power unit 515 is disposed along the optical axis Z direction, the first gear 5161 and the rotation shaft of the power unit 515 are disposed along the optical axis Z direction. Specifically, the first gear 5161 is disposed on the object side of the power unit 515, and the first gear 5161, the second gear 5162, and the third gear 5163 are disposed along the Y-axis direction. The third gear 5163 is coaxially connected to the rotation lever 513, and the third gear 5163 is fixed relative to the rotation lever 513 in the rotation direction.

The present application is not particularly limited in the number of gears. The present application realizes gear reduction by designing the diameters of the gears to be different, thereby increasing the driving force of the gear transmission so that the first driving module 51 provides relatively large thrust. For example, the gear diameter of the first gear 5161, the gear diameter of the second gear 5162, and the gear diameter of the third gear 5163 are sequentially increased, so that the rotation speed is gradually reduced, the driving torque is gradually increased, and a large driving force is generated to drive the lens assembly 2 to smoothly move along the optical axis Z direction.

The axis of rotation of power unit 515 in fig. 13 is disposed along the optical axis Z. In other embodiments, the axis of rotation of power unit 515 may also be oriented in the Y-axis direction. The rotation axis of the first gear 5161 is in the Y-axis direction, the first gear 5161 and the power unit 515 are arranged in the Y-axis direction, and the rotation axis of the second gear 5162 is arranged in the optical axis Z-direction. The first gear 5161 and the second gear 5162 are both helical gears so as to convert rotation about the Y-axis direction into rotation about the optical axis Z-direction. The third gear 5163 is coaxially connected to the rotation lever 513, and the third gear 5163 is fixed relative to the rotation lever 513 in the rotation direction. Of course, the first gear 5161 and the second gear 5162 can be replaced by a worm gear to convert rotation about the Y-axis direction into rotation about the optical axis Z-direction. By providing power unit 515 along the Y-axis, power unit 515 is laterally positioned, which reduces the height of power unit 515 along the Z-axis, allowing for further height reduction of camera module 100.

In this embodiment, the movable member 514 is movably connected to the lens assembly 2, and the movable member 514 has an abutting force on a side of the lens assembly 2 facing away from the photosensitive assembly 3. By designing the movable piece 514 to generate an abutting force on the optical axis object side of the lens assembly 2, the movable piece 514 moves along the optical axis +Z direction under the action of the power unit 515, and a moving space is provided for the extending movement of the lens assembly 2 under the action of the second driving module 52; the movable member 514 moves in the optical axis-Z direction by the power unit 515 to provide a driving force for retraction of the lens assembly 2.

The following is a description of an embodiment of the movable member 514 movably coupled to the lens assembly 2 with reference to the accompanying drawings.

Alternatively, referring to fig. 14 and 15, the movable member 514 acts on the object side of the carrier 21, and the movable member 514 moves along the optical axis+z direction to provide a moving space for the lens assembly 2 to extend out; the movable member 514 moves along the optical axis-Z direction, and the movable member 514 has an abutting force on one side of the lens assembly 2 away from the photosensitive assembly 3, so that the pressing carrier 21 drives the lens assembly 2 to retract into the accommodating cavity 1 a.

It will be appreciated that the connection between the movable member 514 and the lens assembly 2 may be direct or indirect.

In the embodiment in which the movable member 514 is indirectly movably connected to the lens assembly 2, referring to fig. 16, the first driving module 51 further includes a guide member 517 and a connecting member 530. The guide 517, the rotating lever 513, and the power unit 515 are sequentially arranged in the Y-axis direction. The guide 517 is disposed along the optical axis Z. Opposite ends of the guide 517 are fixed to the driving cover 512 and the driving frame 511, respectively. The guide 517 is a sliding rod, and the connecting member 530 is slidably connected to the guide 517. Specifically, the connector 530 may be provided with a notch or through hole (shown schematically as a through hole in fig. 16), through which the connector 530 mates with and slidably engages the outer wall of the guide 517. The present application is not limited to the shape of the cross-section of the guide 517, alternatively, the shape of the cross-section of the guide 517 includes, but is not limited to, square, circular (circular schematic in fig. 16), triangular, and the like. Optionally, the aperture of the through hole sleeved on the guide member 517 by the connecting member 530 is matched with (clearance fit with) the outer diameter of the guide member 517, so as to realize that the connecting member 530 moves relative to the guide member 517 along the optical axis Z direction, and limit the connecting member 530 to relatively rotate in the X-Y plane, thereby improving the stability of the movement of the lens assembly 2 along the optical axis Z direction.

Further, referring to fig. 16, the first driving module 51 further includes a buffer member 518, where the buffer member 518 is sleeved on the guide member 517 and located on the object side of the connecting member 530, and the buffer member 518 moves along with the movement of the connecting member 530. When the buffer 518 abuts against the driving cap 512, the buffer 518 limits the ascending progress of the connecting member 530, and also buffers the movement of the connecting member 530 to the abutment against the driving cap 512.

Referring to fig. 16, a first end 530a of the connecting member 530 abuts against the movable member 514. Specifically, the first end 530a of the connecting member 530 and the movable member 514 abut against each other in the optical axis Z direction. Further, the first end 530a of the connecting member 530 is located at a side facing away from the photosensitive assembly 3. The middle section 530b of the connector 530 is slidably coupled to the outer wall of the guide 517. The second end 530c of the connecting member 530 is connected to the carrier 21 of the lens assembly 2. The first end 530a of the link 530, the middle section 530b of the link 530, and the second end 530c of the link 530 are sequentially aligned in the Y-axis direction.

Optionally, the first end 530a of the connecting member 530 is sleeved on the rotating rod 513, and the aperture of the through hole of the connecting member 530 sleeved on the rotating rod 513 is larger than the outer diameter of the rotating rod 513, so that the connecting member 530 does not touch the rotating rod 513, and the connecting member 530 is not driven to rotate when the rotating rod 513 rotates, so that the stability of the lens assembly 2 in the X-Y plane is not affected.

Of course, in other embodiments, the first end 530a of the connector 530 may also be located outside the rotating lever 513. The front projection of the first end 530a of the connecting member 530 in the optical axis Z direction overlaps with the front projection of the movable member 514 in the optical axis Z direction, so that the first end 530a of the connecting member 530 has a mutual abutment force with the movable member 514 in the optical axis Z direction.

The structure of the connection member 530 is not particularly limited in the present application, and the structure of the connection member 530 and the connection relationship between the connection member 530 and the carrier 21 will be specifically described with reference to the accompanying drawings. Of course, the structure of the connection 530 includes, but is not limited to, the following embodiments.

The carrier 21 is elastically connected to the second end 530c of the connecting member 530 along the optical axis Z, or the carrier 21 elastically abuts against the connecting member 530 along the optical axis Z. The elastic connection means that the carrier 21 and the second end 530c of the connecting member 530 have a certain elastic space with a certain relative movement in the direction of the optical axis Z, and the elastic space may be generated by elastic deformation (elastic deformation is changed into recoverable deformation) of the connecting member 530, or by elastic deformation of the carrier 21, or by elastic deformation of an intermediate connection structure connected between the carrier 21 and the connecting member 530. So that when the lens assembly 2 receives an external impact force, the bearing frame 21 and the second end 530c of the connecting piece 530 are elastically deformed, so as to buffer the external impact force and improve the external impact resistance of the camera module 100; the connecting piece 530 can also load the driving force of the first driving module 51 and the driving force of the second driving module 52 on the moment of the lens assembly 2, buffer the driving force impulse loaded on the lens assembly 2, prevent the lens assembly 2 from popping up and retracting suddenly, and realize that the lens assembly 2 stretches and contracts in a soft and stable manner.

The following description will exemplify the elastic connection of the carrier 21 and the second end 530c of the connecting member 530 in the optical axis Z direction with reference to the accompanying drawings.

Alternatively, referring to fig. 16, 17 and 18, the connecting member 530 is substantially sheet-shaped. The link 530 extends generally along the Y-axis. The first end 530a of the connecting member 530 is suspended and sleeved on the rotating rod 513, the middle section 530b of the connecting member 530 is slidably sleeved on the guiding member 517, and the second end 530c of the connecting member 530 is engaged with the carrier 21. Further, the carrier 21 is engaged with the second end 530c of the connecting member 530 along the optical axis Z direction, so that the carrier 21 and the connecting member 530 move synchronously or substantially synchronously along the optical axis Z direction.

Specifically, referring to fig. 12, the portion of the driving frame 511 corresponding to the second end 530c of the connecting member 530 is a communication opening 511a, and in this embodiment, the carrier 21 extends into the driving frame 511 through the communication opening 511a to be connected to the second end 530c of the connecting member 530. In other embodiments, the second end 530c of the connector 530 extends through the communication opening 511a and connects with the carrier 21.

In the present embodiment, referring to fig. 17 and 18, the second end 530c of the connector 530 has a bite portion 531, and the bite portion 531 forms a bite 531a in the optical axis Z direction.

Referring to fig. 17 and 18, the side of the carrier 21 extending along the Y-axis direction is the first side 214. The first side 214 of the carrier 21 has an extension 215 extending towards the direction in which the connection 530 is located. The protruding portion 215 protrudes into the bite 531a of the bite 531 and abuts against the bite 531.

Specifically, the connecting member 530 has a U-shape at one end (second end 530 c) of the carrier 21, and the opening of the U-shape forms the bite 531a of the bite 531. The bite 531a is a U-shaped space. The bite 531a of the bite 531 faces the first side 214 of the carrier 21. The U-shaped edge of the bite 531 is provided along the optical axis Z direction.

Alternatively, referring to fig. 18, the inner wall of the bite 531a includes a first abutting wall 532 and a second abutting wall 533 disposed opposite to each other in the optical axis Z direction. The extension 215 includes a body portion 2152 and an elastic portion 2151 that are connected. The body 2152 is fixedly coupled to one end of the spring 2151. An elastic space 2153 is formed between the elastic portion 2151 and the body portion 2152. Elastic gap 2153 is located within bite 531a. The main body 2152 abuts against the first abutment wall 532, and the elastic portion 2151 elastically abuts against the second abutment wall 533. It will be appreciated that the resilient portion 2151 is in a compressed state. The body 2152 and the elastic portion 2151 achieve force transmission between the carrier 21 and the link 530 in the optical axis +z direction or the optical axis-Z direction.

In the present embodiment, the first contact wall 532 is located between the second contact wall 533 and the bottom plate 11 (see fig. 4). Optionally, the body portion 2152 is integrally formed with the carrier 21. The main body 2152 is a portion that protrudes from the first side 214 of the carrier 21, and the main body 2152 may extend into the bite 531a of the bite 531 of the connector 530. The elastic portion 2151 is fixed to the side of the carrier 21 facing away from the bottom plate 11, and the shape of the elastic portion 2151 corresponds to the shape of the main body portion 2152. The elastic portion 2151 is bent to form a bent arch. The bent arch abuts against the second abutment wall 533 and forms an elastic gap 2153 with the main body 2152.

During the process of extending the lens assembly 2, the power unit 515 drives the movable element 514 to move towards the optical axis +z direction. The moveable member 514 has a tendency to separate from the connecting member 530. The carrier 21 is moved toward the optical axis +z direction by the driving force of the second driving module 52 toward the optical axis +z direction, and the carrier 21 transmits the driving force to the link 530 through the elastic portion 2151 so that the link 530 moves along the optical axis +z direction along with the movable member 514.

At the moment that the bearing frame 21 receives the driving force towards the optical axis +z direction, since the bearing frame 21 transmits the connecting piece 530 through the elastic part 2151, the elastic part 2151 can absorb the impulse of part towards the optical axis +z direction through generating tiny deformation in the elastic space 2153, so that the bearing frame 21 is prevented from directly striking the connecting piece 530 and directly acting on the first driving module 51, thereby causing damage to the lens assembly 2 or damage to the connecting piece 530 or damage to the first driving module 51, and the sudden movement can be buffered, so that the sudden movement of the lens assembly 2 is avoided, the lens assembly 2 stretches out in a soft manner, the impact resistance of the lens assembly 2 along the optical axis +z direction is further improved, and the reliability of the electronic equipment 1000 is improved. In addition, at the moment when the power unit 515 drives the movable member 514 to descend and the movable member 514 presses the connecting member 530 to descend, the second abutting wall 513 of the connecting member 530 presses the elastic portion 2151 to buffer the instant acting force applied to the lens assembly 2, so as to soften the retracting process of the lens assembly 2.

Optionally, the main body 2152 is flat, and the main body 2152 is in surface-to-surface fit with the first abutment wall 512, so as to facilitate synchronous retraction of the lens assembly 2 and the connector 530 when the lens assembly receives an external impact force.

Of course, in other embodiments, the second abutment wall 513 is located between the first abutment wall 512 and the bottom plate 11. The main body 2152 abuts against the second abutment wall 513, and the elastic portion 2151 abuts against the first abutment wall 512. In this way, the main body 2152 has a compressible space on the side facing the chassis 11, and when the lens assembly 2 is in an extended state and receives an impact force, the elastic portion 2151 can be deformed to cancel a part of the impact force.

Of course, in other embodiments, the main body 2152 may be a deformable elastic structure, in other words, when the lens assembly 2 receives an impact force from the optical axis +z direction or the optical axis-Z direction, the impact force may be buffered by the main body 2152 and the elastic portion 2151, so as to prevent the larger impact force from being directly transmitted to the first driving module 51, and cause damage or deformation of the internal parts of the first driving module 51, and also buffer abrupt extension or abrupt retraction.

The cooperation of the first driving module 51 and the second driving module 52 to drive the lens assembly 2 to extend and retract is illustrated below with reference to the accompanying drawings.

The first driving module 51 and the second driving module 52 are both abutted against the lens assembly 2, and the first driving module 51 and the second driving module 52 have opposite acting forces along the optical axis Z.

The first driving module 51 is used for driving the lens assembly 2 to move along the third direction and providing a moving space for the lens assembly 2 to move along the fourth direction. In the present embodiment, the third direction and the fourth direction are two directions along the optical axis Z and opposite to each other. The third direction is the optical axis image side direction, and the fourth direction is the optical axis object side direction.

The second driving module 52 is used for driving the lens assembly 2 to move in the fourth direction when the first driving module 51 provides a movement space, and providing a movement space for the lens assembly 2 to move in the third direction. In other words, the first driving module 51 acts on the object side of the carrier 21 and has a force toward the image side of the optical axis on the carrier 21, and the second driving module 52 acts on the image side of the carrier 21 and has a force toward the object side of the optical axis on the carrier 21.

The first driving module 51 and the second driving module 52 cooperate to drive the lens assembly 2 to extend and retract, so that the lens assembly 2 moves under the clamping force on two sides along the optical axis Z direction, and compared with the technical scheme that the lens assembly 2 stretches and contracts through the driving force of one driving module, the lens assembly 2 moves under the clamping force on two sides along the optical axis Z direction, and the lens assembly 2 is beneficial to improving the stability of the extending and retracting movement of the lens assembly 2 along the optical axis Z direction.

Optionally, the driving force of the second driving module 52 acting on the image side of the lens assembly 2 includes, but is not limited to, an elastic force and/or a magnetic force. The elastic force and/or the magnetic force makes the second driving module 52 and the image side of the lens assembly 2 not in hard contact (i.e. not rigidly connected). Rigid connection refers to interconnection between two structures without compressible space between them, e.g., rigid connection between screw and nut, rigid connection between gear and screw. When two structures rigidly connected are subjected to impact force, the impact force drives one structure to move, and the other structure resists the movement of the structures, so that physical damage and the like occur to the two structures (for example, the nut moves towards the image side under the action of the impact force, and the screw rod resists the nut to move towards the image side, so that the nut or the screw rod is cracked or damaged). The non-rigid connection such as connection of the elastic member with other structures, connection of the pair of oppositely arranged magnetic members with other structures, connection of the traction rope with other structures, and the like has better impact resistance because the elastic member, the pair of oppositely arranged magnetic members and the traction rope have compressible spaces, and when the elastic member, the pair of oppositely arranged magnetic members and the traction rope are subjected to impact force, part or all of the impact force is buffered through compression of the elastic member, the pair of oppositely arranged magnetic members and the traction rope.

While the lens assembly 2 is in the extended state, a portion of the second driving module 52 moves toward the object side along with the lens assembly 2, and a compressible space is generated between the image side of the carrier 21 and the chassis 11, wherein the compressible space may be generated by stretching the interior of the second driving module 52 or by compressing the interior of the second driving module 52 such that the carrier 21 is away from the chassis 11. When the lens assembly 2 receives an external impact force (or pressing force) towards the optical axis-Z direction, the first driving module 51 does not block the lens assembly 2 from moving towards the image side, the second driving module 52 moves towards the image side along with the lens assembly 2 at the external impact force (or pressing force), at this time, the compressible space between the image side of the carrier 21 and the bottom plate 11 is gradually reduced, and the carrier 21 needs to overcome part of the acting force of the second driving module 51 during the movement process so as to counteract part or all of the external impact force (or pressing force), so that impact damage or external impact force (or pressing force) is prevented from being transmitted to the first driving module 51 through the lens assembly 2, and the problems of damaged internal driving of the first driving module 51 are caused, and the impact resistance of the camera module 100 is improved.

The structure of the second driving module 52 is not particularly limited in the present application, and the structure of the second driving module 52 is illustrated in the following drawings.

In the second driving module 52 provided in the first embodiment, referring to fig. 14 and 15, the second driving module 52 includes an elastic member 520. The driving force provided to the lens assembly 2 by the second driving module 52 is an elastic force. The elastic member 520 is elastically abutted between the carrier 21 and the top plate 12 and/or between the carrier 21 and the bottom plate 11. In the present application, for example, when the elastic member 520 is elastically abutted between the image side of the carrier 21 and the bottom plate 11, the elastic member 520 is compressed in the retracted state of the lens assembly 2, and when the first driving module 51 drives the movable member 514 to move towards the object side of the optical axis, the elastic member 520 pushes the lens assembly 2 to move along the object side of the optical axis, so as to drive the lens assembly 2 to extend; when the elastic member 520 elastically abuts between the object side of the carrier 21 and the top plate 12, the elastic member 520 is stretched when the lens assembly 2 is in the retracted state, and when the first driving module 51 drives the movable member 514 to move toward the object side of the optical axis, the elastic member 520 pulls the lens assembly 2 to move along the object side of the optical axis, so as to drive the lens assembly 2 to extend.

Specifically, referring to fig. 14 and 15, opposite ends of the elastic member 520 (522 or 524) are respectively elastically abutted against the image side of the carrier 21 and the bottom plate 11, the number of the elastic members 520 (522 or 524) is two, or referring to fig. 19 and 20, opposite ends of the elastic member 520 (522 or 524) are respectively elastically abutted against the object side of the carrier 21 and the top plate 12, the elastic member 520 (522 or 524) is in a compressed state, or a part of the elastic member 520 is elastically abutted against the object side of the carrier 21 and the top plate 12, and another part of the elastic member 520 is elastically abutted against the image side of the carrier 21 and the bottom plate 11, or referring to fig. 21 and 22, the number of the elastic members 520 is two, wherein the opposite ends of one elastic member 520 (522 or 524) are respectively elastically abutted against the image side of the carrier 21 and the bottom plate 11, and are in a compressed state, the opposite ends of the other elastic member 520 (525 or 526) are respectively elastically abutted against the object side of the carrier 21 and the top plate 12, and are in a stretched state, and the other elastic member 520 is in an optical axis direction of the carrier 21 is kept stable in the image side or the compressed state. It should be noted that the number and positions of the elastic members 520 are not particularly limited, and the plurality of elastic members 520 are disposed between the object side of the carrier 21 and the top plate 12, and the elastic coefficient of the elastic member 520 close to the first driving module 51 is greater than that of the elastic member 520 far from the first driving module 51, or the number of the elastic members 520 of the first driving module 51 is greater than that of the elastic member 520 far from the first driving module 51, so as to balance the driving force exerted by the first driving module 51 on one side of the carrier 21 and balance the acting force of the carrier 21 in the X-Y plane.

Referring to fig. 14 and 15, the opposite ends of the elastic member 520 elastically abut between the image side of the carrier 21 and the bottom plate 11 for illustration. When the lens assembly 2 is in the retracted state, the first driving module 51 presses the connecting member 530 and the carrier 21 through the movable member 514, so that the lens assembly 2 is accommodated in the accommodating cavity 1a, and the carrier 21 compresses the elastic member 520, so that the elastic member 520 is in the compressed state (i.e. the energy storage state).

When the controller receives the extending command, the controller responds to the extending command and controls the power unit 515 of the first driving module 51 to drive the movable element 514 to move towards the object side of the optical axis through the transmission element 516 and the rotating element 513. When the movable member 514 has a tendency to be separated from the connecting member 530, the connecting member 530 and the carrier 21 are always moved against the movable member 514 under the driving force of the elastic member 520 toward the object side of the optical axis, and during this process, the lens assembly 2 gradually protrudes, and when the power unit 515 drives the movable member 514 to move to the highest position, the lens assembly 2 is located at the protruding position, i.e. in the protruding state. At this time, the elastic member 520 is still in a compressed state, and provides a supporting force to the lens assembly 2 toward the object side of the optical axis, so that the lens assembly 2 stays stably at the extended position.

When the controller receives the retraction command, the power unit 515 of the first driving module 51 is controlled to drive the movable element 514 to move towards the optical axis image side through the transmission element 516 and the rotation element 513 in response to the retraction command. The movable member 514 presses the connecting member 530 and drives the carrier 21 to move towards the image side of the optical axis, and the carrier 21 compresses the elastic member 520 during the movement until the movable member 514 moves to the lowest position, at this time, the lens assembly 2 returns to the retracted position.

Specific structures of the elastic member 520 include, but are not limited to, springs, elastic sheets, elastic columns, and the like. Materials include, but are not limited to, metal, plastic, rubber, silicone, elastomeric composites, and the like. In the present embodiment, the elastic member 520 is a spring.

Alternatively, the number of the elastic members 520 is plural. The present application is not limited to a specific number of elastic members 520. The plurality of elastic pieces 520 are arranged between the image side of the bearing frame 21 and the bottom plate 11 side by side, so that the bearing capacity of the lens assembly 2 can be increased, the uniformity of the driving force of the lens assembly 2 can be increased through arranging the plurality of elastic pieces 520 at intervals, and the stability of the lens assembly 2 extending along the optical axis Z direction is improved.

Alternatively, referring to fig. 14 and 15, the plurality of elastic members 520 includes a first elastic member 522 and a second elastic member 524. The first elastic member 522 and the second elastic member 524 are both exemplified by springs.

Referring to fig. 14 and 15, the second driving module 52 further includes a first guide bar 521. The first guide bar 521 is disposed along the optical axis Z. Alternatively, the first guide bar 521 penetrates the carrier 21, and both ends of the first guide bar 521 are fixed to the top plate 12 and the bottom plate 11, respectively. The carrier 21 is slidably connected to the first guide bar 521. In other words, the first guide bar 521 plays a role of guiding the extension or retraction of the carrier 21. The first guide bar 521 can reduce decentration and tilting during the extension and retraction of the lens assembly 2, and improve the extension or retraction stability of the lens assembly 2. The first elastic member 522 is sleeved on the first guide rod 521. The first guide bar 521 may also serve as a guide bar for the elastic expansion and contraction of the first elastic member 522.

Further, referring to fig. 14 and 15, the second driving module 52 further includes a second guiding rod 523. The second elastic member 524 is sleeved on the second guide rod 523. The second guide lever 523 is disposed along the optical axis Z direction. Alternatively, the second guide rod 523 penetrates the carrier 21, and both ends of the second guide rod 523 are fixed to the top plate 12 and the bottom plate 11, respectively. The carrier 21 is slidably connected to the second guide rod 523. In other words, the second guide rod 523 and the first guide rod 521 both serve to guide the extension or retraction of the lens assembly 2.

In this embodiment, referring to fig. 16 and 17, the first guide rod 521 and the second guide rod 523 are diagonally distributed, so that the first elastic member 522 and the second elastic member 524 generate elastic thrust at two diagonal positions of the carrier 21, which improves the stability of the lens assembly 2 on the X-Y plane, and reduces the problem that one side or one corner of the carrier 21 receives elastic thrust to cause the lens assembly 2 to tilt during the elastic process, thereby causing the problem of jamming and unsmooth stretching process.

Of course, in other embodiments, the first and second guide bars 521 and 523 may be located on opposite sides of the carrier 21. For example, the first guide bar 521 and the second guide bar 523 are aligned in the X-axis direction. The first guide rod 521 and the second guide rod 523 are symmetrically arranged, and the first elastic member 522 and the second elastic member 524 generate elastic thrust on two symmetrical sides of the bearing frame 21, so that the stability of the lens assembly 2 on the X-Y plane is improved.

In other embodiments, one guide bar is grouped with one spring 520. The number of the guide rods and the elastic members 520 can be 3, 4, etc., and the guide rods and the elastic members 520 are uniformly arranged below the bearing frame 21, so that the lens assembly 2 is uniformly driven to extend in the X-Y plane, and the lens assembly 2 is stably extended along the optical axis +Z direction, thereby effectively reducing the problems of blocking, unsmooth extension, etc.

Further, referring to fig. 16 and 17, the first elastic member 522 is close to the connection between the first driving module 51 and the lens assembly 2 with respect to the second elastic member 524. For example, the first drive module 51 is coupled to the first side 214 of the carrier 21. The first elastic member 522 is disposed at a corner portion corresponding to the first side 214, and the second elastic member 524 is disposed at a position diagonal to the first elastic member 522.

The elastic coefficient of the first elastic member 522 is greater than that of the second elastic member 524. That is, the first elastic member 522 is less likely to deform in the optical axis Z direction than the second elastic member 524. In this way, the first elastic member 522 provides a relatively larger elastic force than the second elastic member 524 when the lens assembly 2 is retracted, so as to balance the problem of unbalanced force on the entire carrier 21 due to the first driving module 51 acting on the first side 214 of the carrier 21 as much as possible, and improve the stability of extending or retracting the lens assembly 2.

Alternatively, the diameter of the spring wire of the first elastic member 522 is greater than the diameter of the spring wire of the second elastic member 524; and/or the diameter of the coils of the first resilient member 522 is greater than the diameter of the coils of the second resilient member 524; and/or the number of coils of the first resilient member 522 is greater than the number of coils of the second resilient member 524, etc., such that the spring constant of the first resilient member 522 is greater than the spring constant of the second resilient member 524.

Generally, during retraction of the lens assembly 2, the side of the lens assembly 2 that is closer to the first drive module 51 receives a relatively large pressing force in the optical axis-Z direction, and the side that is farther from the first drive module 51 receives a relatively small pressing force in the optical axis-Z direction. According to the application, the first elastic piece 522 resists a relatively large pressing force with a relatively large elastic coefficient, the second elastic piece 524 resists a relatively small pressing force with a relatively small elastic coefficient, so that the compression of the first elastic piece 522 and the second elastic piece 524 along the optical axis Z direction is basically synchronous, the stability of the lens assembly 2 in the retracting process is improved, and the problems that the side of the lens assembly 2, which is close to the first driving module 51, is inclined under the condition of relatively large pressing force, and the like are avoided.

Referring to fig. 14 and 15, the power unit 515 is configured to drive the movable member 514 to move toward the optical axis +z direction to provide the protruding space of the lens assembly 2, so that the driving force of the movable member 514 required to be provided by the power unit 515 is not required to be great, and energy is saved. The driving force of the lens assembly 2 is provided by the compressed second driving module 52, and by uniformly arranging the plurality of elastic members 520 of the second driving module 52, a uniform pushing force can be provided to reduce the decentration or tilting of the lens assembly 2.

It should be noted that, when the driving force of the second driving module 52 to the lens assembly 2 is an elastic force, the space between the two ends of the elastic member 520 is a compressible elastic space. When the lens assembly 2 extends out of the accommodating cavity 1a and receives an impact force, the lens assembly 2 compresses the compressible elastic space by overcoming the elastic force to offset part or all of the impact force, thereby improving the impact force resistance of the camera module 100.

In the second driving module 52 provided in the second embodiment, referring to fig. 23 and 24, the second driving module 52 includes at least one pair of oppositely disposed magnetic members 550. For example, there are two pairs of magnetic members 550, one of each pair of magnetic members 550 is fixed to the image side of the carrier 21, the other of each pair of magnetic members 550 is fixed to the base plate 11, and each pair of magnetic members 550 repels each other. In other embodiments, referring to fig. 25 and 26, there are two pairs of magnetic members 550, and each pair of magnetic members 550 is disposed between the carrier 21 and the top plate 12, and the magnetic members 550 of each pair attract each other. It should be noted that some of the magnetic members 550 shield a part of the movable member 514. In other embodiments, referring to fig. 27 and 28, the number of the magnetic members 550 is four, wherein two pairs of magnetic members 550 are respectively disposed on the carrier 21 and the bottom plate 11, each pair of magnetic members 550 repel each other, and the other two pairs of magnetic members 550 are respectively disposed on the carrier 21 and the top plate 12, and each pair of magnetic members 550 attract each other.

In the present application, a pair of magnetic members 550 are disposed on the image side of the carrier 21 and the bottom plate 11, and when the pair of magnetic members 550 are disposed on the image side of the carrier 21 and the bottom plate 11, a repulsive force is generated between the pair of magnetic members 550; when the pair of magnetic members 550 are provided on the object side of the carrier 21 and the top plate 12, there is a suction force between the pair of magnetic members 550.

The driving force provided to the lens assembly 2 by the second driving module 52 is a magnetic force. The present embodiment is also provided with a first guide lever 521 and a second guide lever 523 similarly to the above embodiment. The main difference from the above embodiment is that: the first elastic member 522 elastically abutting between the carrier 21 and the base plate 11 is replaced with a pair of opposing and repulsive magnets including, but not limited to, a combination of a permanent magnet and a permanent magnet, a combination of a permanent magnet and an electromagnet, a combination of an electromagnet and an electromagnet, and the like. The second resilient member 524 between the carrier 21 and the base plate 11 is also replaced by a pair of opposing and opposing magnets. Alternatively, the first resilient member 522 between the carrier 21 and the top plate 12 may be replaced with a pair of opposing and opposing magnets, and the second resilient member 524 between the carrier 21 and the top plate may be replaced with a pair of opposing and opposing magnets.

Further, the repulsive force between the pair of magnetic members 550 close to the first driving module 51 may be controlled to be greater than the repulsive force between the pair of magnetic members 550 far from the first driving module 51 to balance the driving force when the power unit 515 is activated, so that the lens assembly 2 is smoothly extended and contracted in the X-Y plane.

It should be noted that, when the driving force of the second driving module 52 to the lens assembly 2 is magnetic force, the space between the pair of repulsive magnetic members 550 is a compressible magnetic space. When the lens assembly 2 extends out of the accommodating cavity 1a and receives an impact force, the lens assembly 2 compresses the compressible magnetic space by overcoming the magnetic repulsive force so as to offset part or all of the impact force, improve the impact force resistance of the camera module 100, effectively protect the lens assembly 2 and improve the fall protection and collision protection capabilities of the camera module 100 of the electronic device 1000.

In the second driving module 52 provided in the third embodiment, referring to fig. 29, the second driving module 52 includes at least one pair of elastic members 520 and at least one pair of oppositely disposed magnetic members 550. Specifically, two magnetic members of the pair of magnetic members 550 are disposed between the carrier 21 and the top plate 12, respectively, and each pair of magnetic members 550 repel each other. Referring to fig. 29 to 31, the elastic member 520 is elastically abutted between the carrier 21 and the top plate 12 and/or between the carrier 21 and the bottom plate 11, and the elastic member 520 is in a compressed or stretched state. The number of the elastic members 520 is plural, and by setting the elastic coefficient (or the number) of the elastic members 520 close to the first driving module 51 to be larger than the elastic coefficient (or the number) of the elastic members 520 far away from the first driving module 51, the driving force of the first driving module 51 on one side of the carrier 21 can be balanced, so that the telescoping stability of the lens assembly 2 is improved.

For example, a pair of magnetic members 550 are disposed on the image side of the carrier 21 and the bottom plate 11, respectively. A pair of magnetic members 550 are magnetically repulsive. The elastic member 520 elastically abuts between the image side of the carrier 21 and the bottom plate 11. Alternatively, the elastic member 520 is compressed. By providing the pair of magnetic members 550 with the elastic member 520 therein, the magnetic members 550 generate a driving force toward the object side of the optical axis for the carrier 21, the elastic member 520 also generates a driving force toward the object side of the optical axis for the carrier 21, and the magnetic members 550 and the elastic member 520 together drive the carrier 21 to extend, and simultaneously, when the lens assembly 2 is retracted, the carrier 21 overcomes the forces of the magnetic members 550 and the elastic member 520, so that the damping of the lens assembly 2 when retracted can be improved, and the lens assembly 2 is smoothly retracted. Of course, in other embodiments, the elastic member 520 may be in a stretched state, and when the magnetic member 550 generates a driving force towards the object side of the optical axis on the carrier 21, the elastic member 520 slows down the driving force of the magnetic member 550 on the carrier 21, so as to damp the extension of the lens assembly 2, so that the lens assembly 2 is gently extended.

Further, the top plate 12 and the bottom plate 11 are provided with guide rods penetrating through corners (or edges) of the carrier 21 and the pair of magnetic members 550, the elastic members 520 are sleeved on the peripheries of the guide rods, and the guide rods provide guidance along the optical axis direction for the movement of the pair of magnetic members 550, the elastic members 520 and the carrier 21.

Referring to fig. 32 to 34, two magnetic members of a pair of magnetic members 550 are disposed between the carrier 21 and the top plate 12, respectively. A pair of magnetic members 550 magnetically attract each other. The elastic member 520 is elastically abutted between the carrier 21 and the top plate 12 and/or between the carrier 21 and the bottom plate 11. The elastic member 520 is stretched or compressed. The number of the elastic members 520 is plural, and by setting the elastic coefficient (or the number) of the elastic members 520 close to the first driving module 51 to be larger than the elastic coefficient (or the number) of the elastic members 520 far away from the first driving module 51, the driving force of the first driving module 51 on one side of the carrier 21 can be balanced, so that the telescoping stability of the lens assembly 2 is improved.

Referring to fig. 35 to 37, two magnetic members of one pair of magnetic members 550 are respectively disposed between the carrier 21 and the top plate 12 and magnetically attracted, and two magnetic members of the other pair of magnetic members 550 are respectively disposed between the carrier 21 and the bottom plate 11 and magnetically repelled. The elastic member 520 is elastically abutted between the carrier 21 and the top plate 12 and/or between the carrier 21 and the bottom plate 11. The elastic member 520 is stretched or compressed. The number of the elastic members 520 is plural, and by setting the elastic coefficient (or the number) of the elastic members 520 close to the first driving module 51 to be larger than the elastic coefficient (or the number) of the elastic members 520 far away from the first driving module 51, the driving force of the first driving module 51 on one side of the carrier 21 can be balanced, so that the telescoping stability of the lens assembly 2 is improved.

In the present embodiment, the lens assembly 2 is extended or retracted by the first driving module 51 and the second driving module 52. Specifically, the camera module 100 further includes a controller (not shown), where the controller is electrically connected to the power unit 515, and the controller controls the rotation of the rotation shaft of the power unit 515, and the rotation shaft of the power unit 515 drives the first gear 5161 to rotate around the Z axis, and then drives the second gear 5162 and the third gear 5163 to rotate in sequence; the third gear 5163 rotates to drive the rotating rod 513 to rotate around the Z axis, and since the movable member 514 is in threaded connection with the rotating rod 513, the rotating rod 513 rotates around the Z axis to drive the movable member 514 to move up and down along the rotating rod 513, i.e. the movable member 514 moves along the Z axis along with the rotating shaft of the rotating rod 513.

The controller responds to the extending instruction to control the power unit 515 to drive the movable piece 514 to move along the object side of the optical axis through the transmission piece 516 and the rotating rod 513, so as to release the movable space of the extending movement of the lens assembly 2. The second driving module 52 pushes the lens assembly 2 to extend out of the accommodating cavity 1a, the bearing frame 21 pushes the connecting piece 530 to move along with the movable piece 514 until reaching the maximum extending position, the power unit 515 stops driving the movable piece 514 to move, the connecting piece 530 stops moving, and the lens assembly 2 is limited by the connecting piece 530 and reaches the extending state. When the lens assembly 2 is in the extended state, the distance between the lens assembly 2 and the photosensitive assembly 3 is within a distance range (i.e. a suitable back focal distance) that can form a clear image, and the camera module 100 is in the working state.

The controller responds to the retraction instruction to control the power unit 515 to reversely rotate, the power unit 515 drives the movable member 514 to move along the optical axis image side through the transmission member 516 and the rotating rod 513, the movable member 514 pushes the connecting member 530 to move towards the optical axis image side, the second driving module 52 comprises an elastic member 520 or a pair of magnetic members 550 with compressible spaces, the compressible spaces inside the second driving module 52 are compressed to provide a moving space for the lens assembly 2 to move towards the image side, and the movable member 514 drives the lens assembly 2 to retract into the accommodating cavity 1a through the connecting member 530 until the lens assembly 2 is in a retracted state.

The application does not limit the position and the direction of the first driving module 51 relative to the lens assembly 2, and the first driving module 51 can be adjusted and determined according to actual conditions, and any direction of the periphery of the lens assembly 2 can be used for the first driving module 51.

According to the camera module 100 provided by the embodiment of the application, the second driving module 52 and the first driving module 51 are arranged, the first driving module 51 is used for providing the extension space for the lens module 2 through the movement of the movable piece 514, namely, after the movable piece 514 moves towards the optical axis +Z direction, the lens module 2 has the extension space so as to extend under the pushing of the second driving module 52, and the lens module 2 extends or retracts under the clamping force of the second driving module 52 and the first driving module 51 along the extension direction, so that the extension stability and the extension controllability of the lens module 2 in the extension process are improved; for the camera module 100 and the electronic device 1000 carrying the lens assembly 2, the lens assembly 2 is in an extending state so as to facilitate interaction between the lens assembly 2 and a user or an external environment, and the lens assembly 2 is in a retracting state so as to improve the concealment of the lens assembly 2, improve the portability of the electronic device 1000, and further save the internal space of the electronic device 1000.

Through setting up the orthographic projection of lens subassembly 2 and first drive module 51 in X axis direction at least partly coincidence to reduce along the size of optical axis +Z direction, and then reduce the space that lens module 22 occupy in optical axis +Z direction, when lens module 22 is camera module 100, photosensitive assembly 3 does not stretch out along with lens subassembly 2, and lens subassembly 2 stretches out for photosensitive assembly 3, in order to increase camera optical system's physical focal length, along with physical focal length's improvement, can improve optical system's performance and surpass the blurring effect behind the field depth, thereby realize the optics blurring. The image obtained by optical blurring can be more natural and beautiful than the image obtained by algorithm blurring, and is more similar to the natural effect watched by human eyes.

The present application will be illustrated with reference to the following drawings for a specific structure in which the first driving module 51 provided in the second embodiment drives the lens assembly 2 to extend in a single pass. The first driving module 51 according to the present embodiment has substantially the same structure as the first driving module 51 according to the first embodiment, and is mainly different in that: referring to fig. 38 and 39, the movable member 514 has an abutting force on a side of the lens assembly 2 facing the photosensitive assembly 3. By designing the movable piece 514 to generate an abutting force on the optical axis image side of the lens assembly 2, the movable piece 514 moves along the optical axis +Z direction to provide a driving force for the extension of the lens assembly 2; the movable member 514 moves along the optical axis-Z direction to provide a moving space for the lens assembly 2 to retract under the action of the second driving module 52.

In the embodiment where the movable member 514 is movably connected to the lens assembly 2, the movable member 514 acts on the image side of the carrier 21, the movable member 514 moves along the optical axis+z direction, and the movable member 514 has an abutment force on the side of the lens assembly 2 facing the photosensitive assembly 3, so that the lens assembly 2 can be pushed out of the accommodating cavity 1a, so that the lens assembly 2 is in an extended state; the movable member 514 moves along the optical axis-Z direction to provide a moving space for the lens assembly 2 to retract into the accommodating cavity 1 a.

Referring to fig. 16, the first end 530a of the connecting member 530 is located on the side of the movable member 514 facing away from the photosensitive assembly 3. I.e., the movable member 514 is located at the image side of the first end 530a of the connecting member 530. The movable member 514 moves along the optical axis +z direction, and pushes the connecting member 530 to move towards the object side, so as to push out the lens assembly 2.

The first driving module 51 is used for driving the lens assembly 2 to move along the third direction and providing a moving space for the lens assembly 2 to move along the fourth direction. Wherein the third direction is an optical axis object side direction (+Z axis), and the fourth direction is an optical axis image side direction (-Z axis).

The second driving module 52 is used for driving the lens assembly 2 to move in the fourth direction when the first driving module 51 provides a movement space, and providing a movement space for the lens assembly 2 to move in the third direction. The third direction and the fourth direction are two opposite directions along the optical axis Z.

In this embodiment, the structure of the second driving module 52 is substantially the same as that of the second driving module 52 in the previous embodiment, and the main difference is that:

the state of the elastic member 520 in the present embodiment is different from the state of the elastic member 520 in the previous embodiment. The elastic member 520 applies a force to the carrier 21 in the direction of the optical axis image side. For example, when the elastic member 520 is provided between the image side of the carriage 21 and the bottom plate 11, the elastic member 520 is in a stretched state. When the elastic member 520 is disposed between the object side of the carrier 21 and the top plate 12, the elastic member 520 is in a compressed state. Of course, the position of the elastic member 520 may also refer to the implementation of the first driving module 51 provided in the first embodiment.

Taking an elastic element 520 between the image side of the carrier 21 and the bottom plate 11 as an example, the controller responds to the extension instruction to control the power unit 515 to drive the movable element 514 to move along the optical axis object side through the transmission element 516 and the rotating rod 513, the movable element 514 drives the lens assembly 2 to extend out of the accommodating cavity 1a through the connecting element 530, in this process, the elastic element 520 between the image side of the carrier 21 and the bottom plate 11 is stretched until reaching the maximum extension position, the power unit 515 stops driving the movable element 514 to move, the connecting element 530 stops moving, and the lens assembly 2 is limited by the connecting element 530 to reach the extension state.

The controller responds to the retraction instruction to control the power unit 515 to reversely rotate, the power unit 515 drives the movable element 514 to move along the optical axis image side through the transmission element 516 and the rotating rod 513, a moving space is provided for the lens assembly 2 to move towards the image side, and an elastic element 520 is arranged between the image side of the bearing frame 21 and the bottom plate 11 to drive the bearing frame 21 to push the connecting element 530 to move along with the movable element 514, so that the lens assembly 2 is driven to retract into the accommodating cavity 1a until the lens assembly 2 is in a retraction state.

In this embodiment, the first driving module 51 is provided to drive the lens assembly 2 to extend in a single pass, and the second driving module 52 is provided to drive the lens assembly 2 to retract in a single pass, because the movable member 514 drives the carrier 21 to extend through the connecting member 530 during the extending process, the movable member 514 is driven by the power unit 515, and the power unit 515 can control the movable member 514 to stay at any position of the rotating rod 513, so that the lens assembly 2 can stay at any position of the extending process, so that the lens assembly 2 can have a plurality of extending states with different extending distances, and different focal lengths between the lens assembly 2 and the photosensitive assembly 3 can be realized; in addition, the driving force of the movable member 514 for extending the lens assembly 2 is a hard force, so that the stability of the lens assembly 2 in the extending state can be improved.

When the second driving module 52 includes at least one pair of magnetic members, the force between the pair of magnetic members 550 in the present embodiment is different from the force between the pair of magnetic members 550 in the previous embodiment. Referring to fig. 28 to 37, a pair of magnetic members 550 generates a force in the optical axis image side direction on the carrier 21. For example, when a pair of magnetic members 550 is disposed between the image side of the carrier 21 and the base plate 11, the pair of magnetic members 550 magnetically attract each other. When a pair of magnetic members 550 are disposed between the object side of the carrier 21 and the top plate 12, the pair of magnetic members 550 magnetically repel each other. Of course, the positions of the pair of magnetic members 550 may also be referred to as implementation in the first driving module 51 provided in the first embodiment.

Further, the arrangement of the guide bar, the positions of the plurality of elastic members 520, the positions of the plurality of pairs of magnetic members 550, etc. in the present embodiment may be referred to as an example in the previous embodiment.

The first driving module 51 includes a motor, a rotation lever 513, and a nut. Of course, in other embodiments, the power unit 515 and the moveable member 514 of the first drive module 51 may be a pair of magnetic members 550.

In the first driving module 51 provided in the third embodiment, referring to fig. 40, a pair of magnetic members 550 of the first driving module 51 are respectively located between the top plate 12 and the object side of the carrier 21, and are magnetically repulsive to each other. The first driving module 51 generates a driving force toward the optical axis image side to the carriage 21. The magnetic member 550 fixed to the top plate 12 is the power unit 515, and the magnetic member 550 fixed to the carrier 21 is the movable member 514. Power unit 515 may be an electromagnet, and moveable member 514 may be an electromagnet, a permanent magnet, a magnetizer, or the like.

Optionally, referring to fig. 40, the second driving module 52 includes an elastic member 520 and guide rods (521, 523). The two ends of the elastic member 520 are respectively elastically abutted between the bottom plate 11 and the image side of the carrier 21, and the elastic member 520 is in a compressed state to generate a driving force toward the object side of the optical axis on the carrier 21. The number of pairs of magnetic members 550 and the number of elastic members 520 may be plural, and the pairs of magnetic members 550 and the plurality of elastic members 520 are uniformly distributed in the X-Y plane of the carrier 21, so as to improve the stability of the lens assembly 2 when extending and retracting.

The controller responds to the extending instruction to control the power unit 515 to reduce the magnetic repulsive force generated by the movable piece 514, the magnetic repulsive force is smaller than the elastic thrust force of the elastic piece 520, and the elastic piece 520 drives the bearing frame 21 to move towards the object side of the optical axis, so that the lens assembly 2 extends until the lens assembly 2 is in the extending position. The controller responds to the retraction command to control the power unit 515 to generate a relatively large magnetic repulsive force on the movable element 514, wherein the magnetic repulsive force is larger than the elastic thrust of the elastic element 520, so as to drive the bearing frame 21 to move towards the optical axis image side, and further realize the retraction of the lens assembly 2 until the lens assembly 2 is in the retraction position.

Of course, in other embodiments, the pair of magnetic members 550 of the first driving module 51 are respectively located between the top plate 12 and the object side of the carrier 21, and magnetically attract each other. The first driving module 51 generates a driving force toward the object side of the optical axis to the carrier 21. The two ends of the elastic member 520 are respectively elastically abutted between the bottom plate 11 and the image side of the carrier 21, and the elastic member 520 is in a stretched state to generate a driving force toward the image side of the optical axis on the carrier 21.

Of course, in other embodiments, the elastic member 520 may be provided between the top plate 12 and the object side of the carrier 21, in a compressed state, to generate a driving force toward the object side of the optical axis on the carrier 21, or provided between the top plate 12 and the object side of the carrier 21 and between the bottom plate 11 and the carrier 21, to generate a driving force toward the object side of the optical axis on the carrier 21. The arrangement of the elastic member 520 in fig. 33 and 34 can be referred to as shown.

Referring to fig. 41, a pair of magnetic members 550 of the first driving module 51 are respectively located between the base plate 11 and the image side of the carrier 21, and magnetically attract each other to generate a force towards the image side of the optical axis on the lens assembly 2 for driving the lens assembly 2 to retract. The two ends of the elastic member 520 of the second driving module 52 are respectively elastically abutted between the top plate 12 and the object side of the carrier 21, and the elastic member 520 is in a stretched state, and generates a force towards the object side of the optical axis on the lens assembly 2, so as to drive the lens assembly 2 to extend. The controller controls the magnitude of the magnetic force between the pair of magnetic pieces 550 of the first driving module 51 to control the lens assembly 2 to extend or retract according to the extending or retracting command.

Of course, in other embodiments, the pair of magnetic members 550 are respectively located between the base plate 11 and the image side of the carrier 21, and magnetically repel each other, so as to generate a force towards the object side of the optical axis on the lens assembly 2. The two ends of the elastic member 520 are respectively elastically abutted between the top plate 12 and the object side of the carrier 21, and the elastic member 520 is in a compressed state to generate a driving force to the carrier 21 toward the object side of the optical axis.

Of course, in other embodiments, the elastic member 520 may be provided between the top plate 12 and the object side of the carrier 21, in a compressed state, to generate a driving force toward the object side of the optical axis on the carrier 21, or provided between the top plate 12 and the object side of the carrier 21 and between the bottom plate 11 and the carrier 21, to generate a driving force toward the object side of the optical axis on the carrier 21. The arrangement of the elastic member 520 of the second driving module 52 can refer to the arrangement of the elastic member 520 in fig. 29 and 31.

Referring to fig. 42, a pair of magnetic members 550 of the first driving module 51 are disposed between the bottom plate 11 and the image side of the carrier 21, and another pair of magnetic members 550 are disposed between the top plate 12 and the object side of the carrier 21. The pair of magnetic members 550 disposed between the bottom plate 11 and the carrier 21 magnetically attract each other, and the other pair of magnetic members 550 disposed between the top plate 12 and the object side of the carrier 21 magnetically repel each other, so that the first driving module 51 generates a driving force toward the optical axis image side on the carrier 21. The elastic member 520 of the second driving module 52 generates a driving force toward the object side of the optical axis to the carrier 21.

Of course, in other embodiments, the elastic member 520 of the second driving module 52 generates a driving force toward the image side of the optical axis on the carrier 21, and the first driving module 51 generates a driving force toward the object side of the optical axis on the carrier 21.

The arrangement of the elastic member 520 of the second driving module 52 can refer to the arrangement of the elastic member 520 in fig. 35 and 37. The elastic member 520 of the second driving module 52 may be disposed between the top plate 12 and the object side of the carrier 21, the elastic member 520 is in a stretched state, or the elastic member 520 of the second driving module 52 may be disposed between the bottom plate 11 and the image side of the carrier 21, and the elastic member 520 is in a compressed state; alternatively, one elastic member 520 of the second driving module 52 is disposed between the top plate 12 and the object side of the carrier 21 and is in a stretched state, and the other elastic member 520 is disposed between the bottom plate 11 and the image side of the carrier 21 and is in a compressed state, and the second driving module 52 generates a driving force to the carrier 21 toward the object side of the optical axis.

The position of the magnetic member 550 of the first driving module 51 and the position of the elastic member 520 of the second driving module 52 may be combined with each other, and will not be described in detail in the present application. The force of the magnetic member 550 of the first driving module 51 against the carrier 21 is opposite to the force of the elastic member 520 of the second driving module 52 against the carrier 21.

The above is an embodiment in which the first driving module 51 cooperates with the second driving module 52 to drive the lens assembly 2 to extend and retract, and the embodiment of the present application also provides an embodiment in which only the first driving module 51 is provided to drive the lens assembly 2 to extend and retract.

The structure of the first driving module 51 provided by the fourth embodiment provided by the embodiment of the present application is illustrated below with reference to the accompanying drawings.

Referring to fig. 43 and 44, the structure of the first driving module 51 provided in the present embodiment is substantially the same as that of the first driving module 51 provided in the first embodiment: the main difference is that in the present embodiment, the movable member 514 is fixedly connected to the carrier 21 of the lens assembly 2, wherein the fixed connection may be a direct fixed connection (i.e. the movable member 514 is directly and fixedly connected to the carrier 21), or an indirect fixed connection (i.e. the movable member 514 is fixedly connected to the carrier 21 through the connecting member 530). The movable member 514 and the carrier 21 move synchronously on the optical axis, and the movable member 514 can move along the optical axis +z direction or along the optical axis-Z direction under the action of the power unit 515, so that the lens assembly 2 can move to the extended position along with the movable member 514 along the optical axis +z direction and to the retracted position along the optical axis-Z direction.

Alternatively, power unit 515 is a motor and moveable member 514 is a nut. The first driving module 51 further comprises a rotating rod 513 and a transmission member 516. The rotating rod 513 is a screw. The transmission 516 includes a plurality of gears. The structure of the first driving module 51 in this embodiment may refer to the corresponding structure of the first driving module 51 in the first embodiment, which is not described herein.

Alternatively, referring to fig. 43 and 44, power unit 515 is a motor, and the rotation axis direction of power unit 515 is along the Y-axis direction. The first drive module 51 further comprises a worm 534, a worm 535, a rotary lever 513, a transmission 516. The rotation axis of the power unit 515 is disposed along the Y-axis direction to reduce the thickness of the first driving module 51, thereby reducing the thickness of the camera module 100. The worm 535 is also disposed along the Y-axis. One end of worm 535 is fixedly connected to the rotational shaft of power unit 515, and when power unit 515 is rotated, worm 535 is rotated therewith, and worm wheel 534 converts the rotation of worm 535 about the Y-axis into rotation about the optical axis Z-direction. The driving member 516 includes a plurality of intermeshing gears. The structure of the transmission member 516 in the present embodiment may refer to the structure of the transmission member 516 in the first driving module 51 provided in the first embodiment. The rotating rod 513 is rotated around the Z axis by the transmission of the transmission member 516, and the movable member 514 is in threaded connection with the rotating rod 513. The power unit 515 outputs rotation, the worm 535 on the power unit 515 drives the turbine 534 to rotate, a transmission member 516 is arranged on the shaft of the turbine 534, and the rotation member is transmitted to the rotation rod 513 through a series of transmission members 516 to push the rotation rod 513 to rotate. When the rotating lever 513 rotates around the Z axis, the movable member 514 moves up and down along the Z axis. The movable member 514 is fixedly connected to the lens assembly 2 to drive the lens assembly 2 to extend or retract.

The power unit 515 provided in this embodiment is placed in the Y-axis direction, and the shape and the profile size of the entire structure can be adjusted. The rotation axis of power unit 515 may be disposed along the Y-axis, i.e., power unit 515 may be disposed laterally, with the rotation of worm wheel 534 and worm 535 translated about the optical axis Z, and with driving member 516 transmitting the drive to moveable member 514. When the power unit 515 is laterally disposed, the thickness of the first driving module 51 in the optical axis Z direction may be reduced, so as to gradually reduce the thickness of the outer profile of the camera module 100, and the thickness of the camera module 100 is reduced in a step manner.

When the power unit 515 is placed transversely (along the Y-axis direction), the gear structure design in the transmission member 516 is synchronously adjusted, so that the thickness of the outer profile is gradually reduced, and the thickness is stepwise reduced. The power unit 515 provided in this embodiment is laterally disposed, and a reduction gear scheme of the worm wheel 534 and the worm 535 can be adopted to achieve a large reduction ratio and self-locking capability, so that the lens assembly 2 cannot retract when the extended lens assembly 2 is reversely pressed.

In the first driving module 51 provided in the fifth embodiment, referring to fig. 45 to 47, the power unit 515 is disposed opposite to or attached to the movable member 514. At least one of power unit 515 and moveable member 514 is an electromagnet. The power unit 515 has magnetic attraction or magnetic repulsion between the movable member 514. The movable member 514 is connected to the carrier 21 along the optical axis Z. Power unit 515 is disposed on top plate 12 and/or bottom plate 11.

For example, the force provided by the first driving module 51 to the lens assembly 2 is magnetic force. Power unit 515 is an electromagnet. The moveable member 514 is an electromagnet, a permanent magnet, or a magnetizer. The movable member 514 may be disposed on an image side or an object side of the carrier 21, and the power unit 515 is disposed opposite to the movable member 514. For example, the movable member 514 is disposed on the object side of the carrier 21, i.e. the movable member 514 and the lens assembly 2 are disposed on the same side of the carrier 21. Power unit 515 is secured to top plate 12 and is disposed opposite moveable member 514. Power unit 515 is an electromagnet, such as a solenoid. The electronic device 1000 also includes a controller. The controller is electrically connected with the power unit 515, and changes the magnetism of the power unit 515 by changing the current flow direction of the power unit 515, so as to change the magnetic force between the power unit 515 and the movable piece 514, so that the power unit 515 is controlled to attract the movable piece 514, and the movable piece 514 moves towards the object side through the carrier 21 and the lens assembly 2, so that the movable piece 514 gradually extends out of the accommodating cavity 1a. When power unit 515 and moveable member 514 are engaged, lens assembly 2 is in the extended maximum position, in which lens assembly 2 is in the extended position, also the imaging position, in which camera module 100 is operational.
