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

The display screen 200 is substantially rectangular. The display screen 200 is a module for displaying images on the electronic device 1000. 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 a surface facing a user when the user normally uses the electronic device 1000.

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. A bezel 302 surrounds the display screen 200. When the electronic device 1000 is substantially rectangular, the frame 302 includes four sides respectively disposed on four sides of the electronic device 1000. 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, and the like, which are disposed in the frame 302, and the middle plate 303 forms a cavity for accommodating the motherboard, the battery, and various electronic components, so that the motherboard, the battery, and the various electronic components can be orderly installed in the electronic device 1000. It can be understood that the screen of the display screen 200 in the present application is relatively large, and the orthographic 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 displaying the image accounts for 85-100% of the area of the front surface of the whole display screen 200.

Referring to fig. 1 and 2, a rear cover 304 covers a side of the frame 302 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 back cover 304. The material of the frame 302 and the rear cover 304 is not limited in particular, for example, the material of the frame 302 and the rear cover 304 includes but is not limited to at least one of plastic, metal, ceramic, glass, etc. The rear cover 304, the middle frame 301 and the display screen 200 surround to form an accommodating space 401, and at least a portion of the camera module 100 is disposed in the accommodating 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 installation hole 402.

The camera module 100 provided by the present application is a camera that can be extended and retracted with respect 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 diagram 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, or the like.

The following describes a specific structure of the camera module 100 with reference to the 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, and the lens group 222 includes a plurality of lenses. Optionally, the lens assembly 2 further includes a light-transmissive cover plate 223, and the light-transmissive cover plate 223 is disposed at an end of the lens barrel 332 facing the object to seal and protect the lens group 222.

The photosensitive assembly 3 is disposed opposite to the lens assembly 2 along the optical axis Z of the lens assembly 2. Here, the optical axis of the lens assembly 2 is also the optical axis of the lens group 222, i.e. 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, the side of the lens assembly 2 facing the object is taken as the object side, and the side of the lens assembly 2 facing the photosensitive assembly 3 is taken as the image side. The subsequent optical axis directions include a direction pointing to the image side along the optical axis (referred to as the optical axis image side direction in this application, the-Z direction in fig. 4), and a direction pointing to the object side along the optical axis (referred to as the optical axis object side direction in this application, the + Z direction in fig. 4).

The photosensitive member 3 includes at least a sensor for converting an optical signal into an image signal, for example, an image sensor. The image sensor and the lens assembly 222 are arranged along the optical axis direction to receive the optical signal transmitted through the lens assembly 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 can be directly connected or interact with each other through magnetic force or the like. The movable member 514 is connected to the lens assembly 2 in a manner not limited to fixed connection or movable connection, wherein the fixed connection includes but not limited to welding, screwing, snap connection, bonding, etc.; the movable connection includes, but is not limited to, abutment of the movable member 514 with the lens assembly 2 in a direction which is not limited to an optical axis image side direction (-Z axis), or an optical axis object side direction (+ Z axis), and the like.

The power unit 515 is configured to drive the moving element 514 to move linearly along an image-side direction (-Z axis), an object-side direction (+ Z axis), or an oblique direction intersecting the optical axis (as long as a certain movement component is present in the optical axis direction), so as to drive the lens assembly 2 to move relative to the photosensitive assembly 3 along the optical axis Z. Optionally, the power unit 515 drives the movable element 514 to move unidirectionally along the image-side direction (-Z axis), unidirectionally along the object-side direction (+ Z axis), or reciprocally along the image-side direction (-Z axis) and the object-side direction (+ Z axis). When the power unit 515 drives the moving member 514 to move linearly, the moving member 514 drives the lens assembly 2 to approach or leave the photosensitive assembly 3 along the optical axis Z, and the distance between the lens assembly 2 and the photosensitive assembly 3 changes, so that the optical focusing of the camera module 100 is realized, and the imaging quality of the camera module 100 is improved.

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

Optionally, in the present application, a position at which the lens assembly 2 is close to the photosensitive assembly 3 with the smallest distance is defined as a retracted position, where the lens assembly 2 is in a retracted state (also referred to as a folded state, a retracted state, etc.), and a position at which the lens assembly 2 is far away from the photosensitive assembly 3 with the largest distance is defined as an extended position, where the lens assembly 2 is in an extended state (also 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, that is, the lens assembly 2 may keep its position during the extension process while the extension portion progresses, and at this time, the camera module 100 may operate in the intermediate extended position as the intermediate extended position. The number of the middle extending positions is not specifically limited in the present application, for example, one middle extending position, three middle extending positions, etc., so as to implement that the camera module 100 operates in different operating states under multiple 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 total length of the camera module 100 is small, so that the camera module 100 can be accommodated in the electronic device 1000 with an extremely limited space. When the lens component 2 is in the extended state, the total length of an optical system formed by the lens component 2 and the photosensitive component 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 exceeding the optical blurring effect after the depth of field is increased, wherein the optical blurring effect obtains more real and brilliant photos than the algorithm blurring effect, because the optical blurring effect is completely different according to the distance of actual scenes, errors can not occur due to the complexity of the scenes, so the embodiment of the application designs the lens component 2 to be far away from the photosensitive component 3 to increase the focal length, and realizes the imaging effect with higher definition and reality.

The camera module 100 that this application embodiment provided, the power unit 515 through designing first drive module 51 drives moving part 514 along linear motion, and moving part 514 drives lens subassembly 2 and moves for photosensitive component 3, and the distance between lens subassembly 2 and the photosensitive component 3 changes, realizes the optics focusing to realize the imaging effect of higher definition and true degree, improve camera module 100's formation of image quality.

It is understood that the specific type of the camera module 100 includes, but is not limited to, one of a main camera, a wide-angle camera, a telephoto camera, a periscopic telephoto camera, a macro camera, etc. or a camera integrating the above-mentioned functions.

Referring to fig. 1 to 4, for the whole electronic device 1000, when the camera module 100 is installed in the installation hole 402 and the accommodating space 401, at least a portion of the lens assembly 2 is disposed in the installation hole 402, and the photosensitive assembly 3 is installed in the accommodating space 401. The lens assembly 2 may be completely received in the mounting hole 402 in the retracted state, for example, a cover plate on the object side of the lens assembly 2 is flush with the outer surface of the rear cover 304 or a 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 protrusion from the outer surface of the back cover 304 to form a height difference between the camera module 100 and the back cover 304, without forming an excessively protruding protrusion on the back cover 304. The lens assembly 2 extends away from the side where the display screen 200 is located 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. The first driving module 51 is used for driving the lens assembly 2 to extend in a single way, or retract in a single way, or reciprocate in two ways.

In the general technology, because the total length of the module of the camera is limited by the thickness of the electronic device 1000, after the total length of the module of the camera is limited, the light-sensitive area of the camera is also limited accordingly, so that the light-sensitive area of the camera is relatively small, and the imaging definition, the fidelity and the like of the camera are influenced to a certain extent. Moreover, the existing camera design is very sensitive to the module height, and an excessively high module height may form a sharp protrusion on the rear cover 304 of the electronic device 1000, which affects the touch feeling and the overall appearance of the rear cover 304 of the electronic device 1000.

This application is stretched out from one side that back lid 304 deviates from display screen 200 through lens subassembly 2 of design camera module 100, and the length that lens subassembly 2 is in the state of stretching out is the module length of camera module 100 normal work, that is to say, the module length of camera module 100 no longer receives the restriction of electronic equipment 1000's thickness, has realized that camera module 100's module length is great relatively and electronic equipment 1000's thickness is less compatibility relatively. Because camera module 100 has relatively great length when the state of stretching out, so, the formation of image size that realizes the photosensitive assembly 3 of camera module 100 also can set up relatively great (the big end sensitization promptly) to make camera module 100's daylighting area relatively great, and then obtain the better image of quality. In the present embodiment, since the surface on which the photosensitive element 3 is located is the long and wide surface of the electronic apparatus 1000, the electronic apparatus 1000 itself has a large carrying space on the surface on which the photosensitive element 3 is located, and therefore the electronic apparatus 1000 also has the potential to accommodate 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 does not form a protruding 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, and improves the portability of the electronic device 1000.

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

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 side plate 13 surround and form a housing chamber 1 a. It will be understood that the top panel 12, bottom panel 11 and peripheral side panel 13 are only divided in orientation. The top panel 12 may be integrally formed with a portion of the peripheral side panel 13, and the bottom panel 11 may be integrally formed with another portion of the peripheral side panel 13.

Referring to fig. 4, at least a portion of the lens assembly 2 is disposed in the accommodating case 1. The top plate 12 has a telescopic hole 1 b.

The focusing module 41 and the optical anti-shake module 42 are both 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 the periphery of the magnetic coil assembly 412. The first carrier 411, the plurality of first magnetic assemblies 413 and the adjusting shell 40 are fixed relatively. The solenoid coil assembly 412 has a second through hole 412 a. The second through hole 412a of the solenoid coil block 412 corresponds to and is conducted with the first through hole 40a of the adjustment case 40. The electromagnetic coil assembly 412 surrounds the periphery of the lens assembly 2. The solenoid 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, the electromagnetic coil assembly 412 receives the electrical signal and generates a first magnetic force with the first magnetic assembly 413. Since the first magnetic assembly 413 is fixed relative to the carrier 21. The electromagnetic coil assembly 412 can move in the optical axis direction, so the first magnetic force drives the electromagnetic coil assembly 412 to move along the optical axis image side or the optical axis object side, 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 is understood that the movement amount of the focus module 41 with respect to the lens assembly 2 in the optical axis Z direction is much smaller than the movement amount of the first driving module 51 driving the lens assembly 2. The focusing module 41 is different from the first driving module 51 in that the former is fine adjustment to an optimum focal length in a focal length range at the time of imaging, and the latter is to increase the distance between the lens assembly 2 and the photosensitive assembly 3 from a very small pitch to within 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 element 423. The second carrier 421 is disposed opposite to at least a portion of the first carrier 411. The second carrier 421 has a third through hole 421 a. The third through hole 421a of the second carrier 421 corresponds to and is conducted with the second through hole 412a of the electromagnetic coil assembly 412. The second carrier 421 surrounds the lens assembly 2. The second carrier 421 is connected to the lens assembly 2. The plurality of first magnetic assemblies 413 are further configured to drive the second magnetic assembly 423 to move the lens assembly 2 along a direction perpendicular to the optical axis. Specifically, the plurality of first magnetic members 413 are disposed around the circumferential side of the second magnetic member 423. The second magnetic component 423 receives the electrical signal and generates a second magnetic force with the first magnetic component 413. Since the first magnetic assembly 413 is fixed relative to the carrier 21. The second magnetic component 423 can move on a plane perpendicular to the optical axis direction, so that the second magnetic force drives the second magnetic component 423 to drive the second supporting body 421 and the lens component 2 to move along the direction perpendicular to the optical axis Z, so as to compensate displacement offset caused by shake in the shooting process, thereby implementing the optical anti-shake function of the camera module 100.

Further, at least a portion of the guide 422 is in rolling contact with the first carrier 411. The guide portion 422 includes a guide rail 4221 and a rolling portion 4222 that is connected to the guide rail 4221 in a rolling manner. The guide 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 connected to the first carrier 411 in a rolling manner to improve the smoothness of movement when the first carrier 411 and the second carrier 421 move relatively.

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 parts 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 in all of the four corner portions 421, the smoothness of the movement of the second carrier 421 in the plane perpendicular to the optical axis Z direction is improved. Since the lens assembly 2 is cylindrical. The second supporting body 421 is rectangular, and the guiding portion 422 is disposed at the corner 4211, so that the space at the corner 4211 of the second supporting body 421 can be fully utilized, and the volume of the whole lens assembly 2 and the whole adjusting assembly 4 can be further reduced.

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

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

The controller of the electronic device 1000 forms an electric signal to compensate for the displacement change generated during photographing, according to the displacement change. The first magnetic assembly 413 and/or the second magnetic assembly 423 are displaced in the X-axis direction and the Y-axis direction respectively after receiving the electrical signal, so as to move the lens assembly 2 in the X-Y plane, including but not limited to moving in the positive X-axis direction, moving in the negative X-axis direction, moving in the positive Y-axis direction, moving in the negative Y-axis direction, moving in the diagonal direction, and so on. This embodiment can realize that the lens assembly 2 performs optical anti-shake compensation 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 made of a deformable structure that can be deformed in the X-axis direction and the Y-axis direction, for example, a deformable structure made of electrostrictive material, specifically, shape memory alloy, piezoelectric ceramic, ferroelectric polymer, etc. The controller of the electronic device 1000 forms an electric signal to compensate for the displacement change generated during photographing, according to the displacement change. The deformation structure receives the electric signal 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 so as to drive the lens assembly 2 to move in an X-Y plane, perform optical anti-shake compensation and further improve the imaging quality of the camera module 100.

In the adjusting assembly 4 provided in the second embodiment, referring to fig. 10, the adjusting assembly 4 is disposed on the peripheral side of the photosensitive assembly 3 and fixed relative to the photosensitive assembly 3. Optionally, the adjusting assembly 4 is disposed on the bottom plate 11 and fixed relative to the photosensitive assembly 3. Specifically, the adjusting assembly 4 surrounds the periphery of the photosensitive assembly 3, and is used for adjusting the photosensitive assembly 3 to move along the optical axis Z direction relative to the lens assembly 2 so as to realize automatic focusing, and is also used for adjusting the photosensitive assembly 3 to move along a plane perpendicular to the optical axis Z direction relative to the lens assembly 2 so as to realize an optical anti-shake function. Through locating adjusting part 4 and accepting chamber 1a in, need not to stretch out with camera lens subassembly 2 together, reducible structure volume that need stretch out, and then reduced the size and the weight of the structure that need stretch out, reduce the required driven weight of first drive module 51, save the electric energy, improve electronic equipment 1000's length of use. When the adjustment assembly 4 is not extended with the lens assembly 2, the lens assembly 2 may be rounded in profile to reduce the volume of the structure that needs to be extended. The specific structure of the adjusting assembly 4 in the present embodiment can refer to the structure in fig. 9.

In other embodiments of the adjustment 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; alternatively, the focusing module 41 is disposed on the periphery of the lens assembly 2, and the optical anti-shake module 42 is disposed on the periphery of the photosensitive assembly 3, so as to improve the flexibility of the camera module 100 by the flexible design, and adaptively select the appropriate arrangement mode of the adjusting assembly 4 based on different requirements.

Referring to fig. 11, the supporting frame 21 is substantially square, the supporting frame 21 is a hollow structure, and a hollow channel in the middle of the supporting frame 21 provides a light communication channel between the lens assembly 2 and the photosensitive assembly 3. Four extending portions 212 extend from four corners of the supporting frame 21 toward the hollow structure, the four extending portions 212 all extend toward the center of the supporting frame 21, and the bottom of the lens module 2 is provided with recessed portions 213 corresponding to the four extending portions 212. Each of the extending portions 212 is disposed in a recessed portion 213 so that the lens assembly 2 is aligned with the carriage 21 and does not move relative to each other in the X-Y plane.

By providing the carrier 21, the first driving module 51 moves through the driving carrier 21, the carrier 21 is fixedly connected to the lens module 22, and the carrier 21 drives the lens module 22 to move, so that the structure directly connected to the first driving module 51 is not required to be provided on the lens module 22, but the structure connected to the first driving module 51 is provided on the carrier 213. It should be noted that, in the present application, since the lens module 22 is synchronized with the movement of the carrier 21, when describing that the carrier 21 is driven to move in a certain direction, it also means that the lens module 22 is driven to move in the same direction in synchronization.

Of course, in other embodiments, the carriage 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, retract or reciprocate in a single stroke.

The arrangement between the first driving module 51 and the lens assembly 2 is not particularly limited in the present application. The following description will exemplify 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 fig. 5, an orthographic projection of the first driving module 51 in the first direction at least partially coincides with an orthographic 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 in the X-Y plane. For example, the first direction is the X direction in fig. 4.

The orthographic projection of the first drive module 51 in the first direction at least partially overlaps with the orthographic projection of the lens assembly 2 in the first direction, so that the height of the first drive module 51 and the height of the lens assembly 2 in the direction of the optical axis Z at least partially overlap, and the size of the first drive module 51 and the size of the lens assembly 2 in the direction of the optical axis Z are reduced.

Specifically, the first driving module 51 and the lens assembly 2 are arranged in a direction not 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 in 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 one 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 small drop height 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 size of the camera module 100 along the optical axis Z direction and is also beneficial to realizing the optical design of large bottom, large optical aperture and long focal length of the rear camera.

In another embodiment, the first drive module 51 is aligned with the lens assembly 2 in a direction that is oblique to the X-Y plane.

In the present embodiment, the first driving module 51 and the lens assembly 2 are arranged in a direction intersecting with the optical axis Z instead of being stacked in the optical axis Z direction, so that the stacking dimension of the first driving module 51 and the lens assembly 2 in the optical axis Z direction can be reduced, and since the optical axis Z direction is also the thickness direction of the electronic device 1000, the stacking dimension of the camera module 100 in the thickness direction of the electronic device 1000 is reduced, and the electronic device 1000 is facilitated to be light and thin.

From another perspective, the lens assembly 2 and the photosensitive assembly 3 are taken as a whole, and the first driving module 51 is located at a side surface of the whole of the lens assembly 2 and the photosensitive assembly 3, where the side surface is the side except the image side and the object side. It should be noted that "image side" herein refers to a pointing side of an object facing the image side of the optical axis, and "object side" refers to a pointing side of an object facing the object side of the optical axis, and other structures may be further described with the image side and the object side as reference sides, which are not repeated.

The present application does not specifically limit the positional relationship between the first drive module 51 and the housing case 1. Optionally, the first driving module 51 is disposed in the accommodating case 1.

Referring to fig. 4 and 12, the first driving module 51 has a driving shell 510, and an inner cavity of the driving shell 510 is communicated with the accommodating cavity 1a of the accommodating shell 1. A partial surface of the driving case 510 is spliced with a partial surface of the receiving case 1 to form a complete surface. For example, referring to fig. 6 and 8, the plate facing the object side of the driving shell 510 and the top plate 12 of the accommodating shell 1 are spliced to form a plate facing the object side of the camera module 100. The plate of the driving shell 510 facing the image side is disposed on the bottom plate 11 of the accommodating shell 1, so that the accommodating shell 1 carries the driving shell 510. First drive module 51 can assemble as an independent module production back and accommodate the lens subassembly 2 in the shell 1, so, camera module 100 can fall into two independent modules at least and process and assemble, has avoided the inconvenience that needs the unit mount, improves equipment convenience and efficiency, and also is convenient for change when one of them module damages.

With respect to the internal structure of the first driving module 51, referring to fig. 13, an orthographic projection of the movable member 514 in the first direction at least partially coincides with an orthographic projection of the lens assembly 2 in the first direction. An orthographic projection of the power unit 515 in the second direction at least partially overlaps with an orthographic projection of the movable member 514 in the second direction, the second direction is perpendicular to the optical axis Z direction, and the second direction intersects with the first direction. The second direction is a direction intersecting the first direction in the X-Y plane. By arranging the movable member 514, the lens assembly 2 and the power unit 515 side by side in the X-Y plane, 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 in the Z direction of the optical axis is reduced, and the optical design of a large bottom, a large optical aperture and a long focal length of the rear camera is realized.

Optionally, the second direction is perpendicular to the first direction, for example, the second direction is a Y-axis direction. By arranging the movable element 514 and the power unit 515 in a direction perpendicular to the direction in which the movable element 514 and the lens assembly 2 are arranged, the movable element 514, the power unit 515 and the lens assembly 2 are compactly arranged on an X-Y plane, the area of the whole camera module 100 on the X-Y plane is further reduced, and miniaturization of the camera module 100 is promoted.

The overall outer contour of the lens assembly 2 is not particularly limited in the present application, and may be, for example, circular, square, or the like. Adjusting components (see the 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 periphery of the lens assembly 2, and the overall outer contour of the encapsulated lens assembly 2 is rectangular. One side of the lens component 2 is along the X-axis direction, and the other side is along the Y-axis direction. Specifically, the first direction is an X-axis direction, and the second direction is a Y-axis direction. In this way, the movable member 514 and the power unit 515 are arranged beside the side of the lens assembly 2 extending in the Y-axis direction, 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, the stacking dimension in the optical axis Z direction is small, and miniaturization of the camera module 100 is facilitated. Furthermore, the power unit 515 acts on the movable element 514 in the second direction to make the movable element 514 move linearly along the optical axis Z direction or move along an inclined linear direction (e.g., the movable element 514 moves along an inclined surface of the inclined slider) and have a movement component along the optical axis Z direction, so as to drive the lens assembly 2 to move along the optical axis Z direction, and the above-mentioned process realizes the conversion of the driving force in the X-Y plane into the acting force in the optical axis Z direction.

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

In the present application, the first driving module 51 may be used to drive the lens assembly 2 to extend or retract back and forth, in a single pass.

The following description will be made with reference to the accompanying drawings for illustrating a specific structure of the first embodiment in which the first driving module 51 drives the lens assembly 2 to retract in a single stroke. In the process that the first driving module 51 drives the lens assembly 2 to retract in a single pass, 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 disposed in the driving housing 510. The rotating lever 513 is disposed in 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 screwed to the rotating rod 513.

Optionally, the rotating rod 513 is a lead screw, the moving member 514 is a nut, and an internal thread of the moving member 514 is connected with an external thread of the rotating rod 513. The power unit 515 drives the rotating rod 513 to rotate (rotate) to drive the movable member 514 to move along the rotating rod 513 (i.e., the optical axis + Z direction or-Z direction).

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 rotating rod 513 are sequentially arranged along the Y-axis direction to reduce the area occupied by the whole module in the X-axis direction. The power unit 515 is configured to drive 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 transmission 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 which are meshed and connected in sequence. The number of the second gears 5162 is at least one. The first gear 5161 is coaxially connected with the rotation shaft of the power unit 515. The third gear 5163 is coaxially connected with the rotating lever 513.

The power unit 515 is a motor, and a rotation shaft of the power unit 515 is disposed along the optical axis Z direction or along the Y axis direction. When the power unit 515 is disposed in the optical axis Z direction, the first gear 5161 and the rotation shaft of the power unit 515 are disposed in 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 rotating lever 513, and the third gear 5163 is relatively fixed to the rotating lever 513 in the rotating direction.

The number of gears is not particularly limited in the present application. The diameter of this application through the design gear is different to realize gear reduction, and then increase gear drive's drive power size, so that first drive module 51 provides great thrust relatively. 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 to gradually decrease the rotational speed and gradually increase the transmission torque, thereby generating a large driving force to drive the lens assembly 2 to smoothly move in the optical axis Z direction.

The rotation axis of the power unit 515 in fig. 13 is arranged along the optical axis Z direction. In other embodiments, the rotation axis of the power unit 515 may also be arranged along the Y-axis direction. The rotating shaft of the first gear 5161 is in the Y-axis direction, the first gear 5161 and the power unit 515 are arranged along the Y-axis direction, and the rotating shaft of the second gear 5162 is arranged along 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 rotating lever 513, and the third gear 5163 is relatively fixed to the rotating lever 513 in the rotating direction. Of course, the first gear 5161 and the second gear 5162 may be replaced by worm gears, so that the rotation around the Y-axis direction is converted into the rotation around the optical axis Z direction. By arranging the power unit 515 along the Y-axis direction and arranging the power unit 515 transversely, the height of the power unit 515 along the Z-axis direction can be reduced, and conditions can be created for further reducing the height of the camera module 100.

In this embodiment, the movable element 514 is movably connected to the lens assembly 2, and the movable element 514 has a contact force against a side of the lens assembly 2 away from the photosensitive element 3. By designing the movable element 514 to generate a contact force on the optical axis side of the lens assembly 2, the movable element 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 along the optical axis-Z direction under the action of the power unit 515 to provide a driving force for retracting the lens assembly 2.

The following description of the embodiment of the movable lens assembly 2 with the movable member 514 is provided with reference to the accompanying drawings.

Optionally, referring to fig. 14 and fig. 15, the movable element 514 acts on the object side of the carrier 21, and the movement of the movable element 514 along the optical axis + Z direction can provide a moving space for the lens assembly 2 to extend out; the movable element 514 moves along the optical axis-Z direction, and the movable element 514 has a contact force against a side of the lens assembly 2 away from the photosensitive element 3, so as to press the bearing frame 21 to drive the lens assembly 2 to retract into the accommodating cavity 1 a.

It is understood that the movable member 514 and the lens assembly 2 may be directly connected or indirectly connected.

In the embodiment of the lens assembly 2 indirectly movably connected to the movable member 514, referring to fig. 16, the first driving module 51 further includes a guiding 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 connecting member 530 may be provided with a notch or a through hole (schematically shown as a through hole in fig. 16), and the connecting member 530 is engaged with and slidably connected to the outer wall of the guide 517 through the notch or the through hole. The shape of the cross section of the guide 517 is not limited in this application, and alternatively, the shape of the cross section of the guide 517 includes, but is not limited to, a square, a circle (illustrated as a circle in fig. 16), a triangle, and the like. Optionally, the aperture of the through hole of the connecting member 530 sleeved on the guide 517 is adapted to the outer diameter of the guide 517 (in a clearance fit manner), so that the connecting member 530 moves relative to the guide 517 along the optical axis Z direction, and the connecting member 530 is limited to rotate relatively in the X-Y plane, thereby improving the stability of the lens assembly 2 moving along the optical axis Z direction.

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

Referring to fig. 16, a first end 530a of the connecting member 530 abuts 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 member 3. The middle section 530b of the connecting member 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 connection member 530, the middle section 530b of the connection member 530, and the second end 530c of the connection member 530 are sequentially arranged 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 rotating rod 513 sleeved by the connecting member 530 is larger than the outer diameter of the rotating rod 513, so that the connecting member 530 does not touch the rotating rod 513, so that the rotating rod 513 cannot drive the connecting member 530 to rotate when rotating, and further the stability of the lens assembly 2 on the X-Y plane cannot be affected.

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

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

The carriage 21 is elastically connected to the second end 530c of the connecting member 530 in the direction along the optical axis Z, or the carriage 21 elastically abuts against the connecting member 530 in the direction along the optical axis Z. The elastic connection means that the second ends 530c of the bearing frame 21 and the connecting member 530 have an elastic space with a certain relative movement in the optical axis Z direction, and the elastic space may be generated by the elastic deformation of the connecting member 530 (the elastic deformation is recoverable deformation), may also be generated by the elastic deformation of the bearing frame 21, or may be generated by the elastic deformation of an intermediate connecting structure connected between the bearing frame 21 and the connecting member 530. When the lens assembly 2 is subjected to an external impact force, the elastic deformation occurs between the bearing frame 21 and the second end 530c of the connecting member 530 to buffer the external impact force, so as to improve the external impact resistance of the camera module 100; the connecting member 530 can also apply the driving force of the first driving module 51 and the driving force of the second driving module 52 to the lens assembly 2 at the moment, so as to buffer the driving force impulse applied to the lens assembly 2, prevent the lens assembly 2 from popping up and retracting suddenly, and realize that the lens assembly 2 stretches and retracts in a soft and stable manner.

The elastic connection between the bearing frame 21 and the second end 530c of the connecting member 530 in the optical axis Z direction is exemplified in the following with reference to the drawings.

Alternatively, referring to fig. 16, 17 and 18, the connecting member 530 is substantially plate-shaped. The link 530 extends substantially in the Y-axis direction. 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 guide member 517, and the second end 530c of the connecting member 530 is engaged with the supporting frame 21. Further, the carrier 21 and the second end 530c of the link 530 are snap-coupled in the optical axis Z direction, so that the carrier 21 and the link 530 move synchronously or substantially synchronously in the optical axis Z direction.

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

In this embodiment, referring to fig. 17 and 18, the second end 530c of the connecting member 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 carriage 21 extending along the Y-axis direction is a first side 214. The first side 214 of the carrier 21 has a protrusion 215 extending in the direction of the link 530. The protruding portion 215 protrudes into the bite 531a of the bite portion 531 and abuts against the bite portion 531.

Specifically, one end (the second end 530c) of the link 530 connected to the carrier 21 has a U-shape, and an opening of the U-shape forms a bite 531a of the bite portion 531. The bite 531a is a U-shaped space. The bite 531a of the bite portion 531 faces the first side edge 214 of the carrier 21. The U-shaped edge of the nip portion 531 is arranged along the optical axis Z direction.

Alternatively, referring to fig. 18, the inner wall of the mouthpiece 531a includes a first abutting wall 532 and a second abutting wall 533 disposed oppositely in the optical axis Z direction. The extension 215 includes a body portion 2152 and an elastic portion 2151 connected to each other. The body portion 2152 is fixedly connected to one end of the elastic portion 2151. Resilient portion 2151 forms a resilient gap 2153 with body portion 2152. Elastomeric spaces 2153 are located within mouthpiece 531 a. The body portion 2152 abuts against the first abutting wall 532, and the elastic portion 2151 elastically abuts against the second abutting wall 533. As can be appreciated, the resilient portion 2151 is in a compressed state. Main body portion 2152 and elastic portion 2151 realize force transmission between carriage 21 and link 530 in the optical axis + Z direction or the optical axis-Z direction.

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

During the process of extending the lens assembly 2, the power unit 515 drives the movable member 514 to move toward the + Z direction of the optical axis. Moveable member 514 has a tendency to disengage from connecting member 530. The carrier 21 is driven by the second driving module 52 to move in the direction of the optical axis + Z, and the carrier 21 transmits the driving force to the connecting member 530 through the elastic portion 2151, so that the connecting member 530 moves in the direction of the optical axis + Z in close contact with the movable member 514.

At the moment that the bearing frame 21 is subjected to 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 part of the impulse towards the optical axis + Z direction by generating a small deformation in the elastic space 2153, so that the bearing frame 21 is prevented from directly impacting the connecting piece 530 suddenly and directly acting on the first driving module 51 to cause damage to the lens assembly 2, the connecting piece 530 or the first driving module 51, and the sudden movement can be buffered to prevent the lens assembly 2 from moving suddenly, so that the lens assembly 2 extends 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 device 1000 is improved. In addition, at the moment that the power unit 515 drives the movable member 514 to descend and the movable member 514 presses the connection member 530 to descend, the second abutting wall 513 of the connection 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 portion 2152 is straight, and the main body portion 2152 is in surface contact with the first abutting wall 512, so that the lens assembly 2 can be retracted synchronously with the connecting member 530 when receiving an external impact force.

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

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

The cooperation between the first driving module 51 and the second driving module 52 to drive the lens assembly 2 to extend and retract is illustrated in the following with reference to the 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 opposite directions along the optical axis Z. The third direction is an optical axis image side direction, and the fourth direction is an optical axis object side direction.

The second driving module 52 is configured to drive the lens assembly 2 to move in the fourth direction when the first driving module 51 provides a movement space, and to provide 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.

Cooperate with the stretching out and withdrawing of drive lens subassembly 2 through first drive module 51 and second drive module 52 to lens subassembly 2 moves under receiving the clamping force of both sides along optical axis Z direction, compare in lens subassembly 2 through the flexible technical scheme of drive force of a drive module, this application is moved under receiving the clamping force of both sides along optical axis Z direction through lens subassembly 2, helps improving the motion stationarity that lens subassembly 2 stretches out and withdraws along optical axis Z direction.

Optionally, the driving force applied by the second driving module 52 to 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 make the second driving module 52 and the image side of the lens assembly 2 in non-rigid contact (i.e. non-rigid connection). Rigid connection means that two structures are connected with each other and there is no compressible space between the two structures, for example, rigid connection is formed between a screw rod and a nut, and rigid connection is formed between a gear and the screw rod. When two rigidly connected structures are subjected to an impact force, the impact force drives one structure to move, and the other structure prevents the structures from moving, so that the two structures are physically damaged (for example, the nut moves towards the image side under the action of the impact force, and the lead screw prevents the nut from moving towards the image side, so that the nut or the lead screw is cracked or damaged). The non-rigid connection such as the connection of the elastic element and other structures, the connection of the pair of oppositely arranged magnetic elements and other structures, the connection of the traction rope and other structures and the like has better impact resistance because the elastic element, the pair of oppositely arranged magnetic elements and the traction rope have compressible spaces and buffer part or all of impact force through the compression of the elastic element, the pair of oppositely arranged magnetic elements and the traction rope when the traction rope is subjected to the impact force.

When the lens assembly 2 is in the extended state, while a portion of the second driving module 52 moves toward the object side along with the lens assembly 2, a compressible space is generated between the image side of the carrier 21 and the bottom plate 11, and the compressible space may be generated by stretching the inside of the second driving module 52 or by compressing the inside of the second driving module 52 so that the carrier 21 is away from the bottom plate 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 bearing frame 21 and the bottom plate 11 is gradually reduced, and the bearing frame 21 needs to overcome a part of the acting force of the second driving module 51 in the moving process to offset a part or all of the external impact force (or pressing force), so as to avoid the problems of internal driving damage of the first driving module 51 and the like caused by that the impact damage or the external impact force (or pressing force) is transmitted to the first driving module 51 through the lens assembly 2, and improve the impact resistance of the camera module 100.

The structure of the second driving module 52 is not specifically limited in the present application, and the structure of the second driving module 52 is illustrated in the following description with reference to the drawings.

In the second driving module 52 provided in the first embodiment, please refer to fig. 14 and fig. 15, the second driving module 52 includes an elastic element 520. The driving force provided by the second driving module 52 to the lens assembly 2 is an elastic force. The elastic member 520 elastically abuts between the carrier 21 and the top plate 12 and/or between the carrier 21 and the bottom plate 11. For example, when the elastic member 520 is elastically abutted between the image side of the supporting frame 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 toward the object side, the elastic member 520 pushes the lens assembly 2 to move along the object side, so as to drive the lens assembly 2 to extend; when the elastic member 520 is elastically abutted between the object side of the supporting frame 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, two opposite ends of the elastic element 520(522 or 524) respectively elastically abut against the image side and the bottom plate 11 of the frame 21, the elastic element 520(522 or 524) is in a compressed state, or, referring to fig. 19 and 20, two opposite ends of the elastic element 520(522 or 524) respectively elastically abut against the object side and the top plate 12 of the frame 21, the elastic element 520(522 or 524) is in a compressed state, or a part of the elastic element 520 elastically abuts between the object side and the top plate 12 of the frame 21, and another part of the elastic element 520 elastically abuts between the image side and the bottom plate 11 of the frame 21, or, referring to fig. 21 and 22, two elastic elements 520 are provided, wherein two opposite ends of one elastic element 520(522 or 524) respectively elastically abut against the image side and the bottom plate 11 of the frame 21 and are in a compressed state, and two opposite ends of the other elastic element 520 (525) respectively elastically abut against the object side and the top plate 12 of the frame 21, the carriage 21 is stretched or compressed, and an elastic force is applied to the image side or the object side of the optical axis of the carriage 21, so that the carriage 21 can maintain good stability in the direction of the optical axis Z. It should be noted that the number and the positions of the elastic members 520 are not limited specifically, a 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 the elastic coefficient of the elastic member 520 away from the first driving module 51, or the number of the elastic members 520 of the first driving module 51 is greater than the number of the elastic members 520 away from the first driving module 51, so as to balance the driving force exerted by the first driving module 51 on the side of the carrier 21 and balance the acting force of the carrier 21 in the X-Y plane.

Referring to fig. 14 and fig. 15, the two opposite ends of the elastic element 520 are elastically abutted between the image side of the loading frame 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 supporting frame 21 via the movable member 514, so that the lens assembly 2 is accommodated in the accommodating cavity 1a, and the supporting frame 21 compresses the elastic member 520, so that the elastic member 520 is in a compressed state (i.e., an energy storage state).

When receiving the extending instruction, the controller responds to the extending instruction and controls the power unit 515 of the first driving module 51 to drive the movable element 514 to move toward the optical axis object side through the transmission element 516 and the rotating element 513. When the movable element 514 tends to separate from the connecting element 530, the connecting element 530 and the supporting frame 21 are always pressed against the movable element 514 by the driving force of the elastic element 520 toward the optical axis side, and during this process, the lens assembly 2 gradually extends, and when the power unit 515 drives the movable element 514 to move to the highest position, the lens assembly 2 is located at the extended position, i.e., in the extended state. At this time, the elastic member 520 is still in a compressed state, and provides a supporting force toward the object side of the optical axis for the lens assembly 2, so that the lens assembly 2 stably stays at the extended position.

When receiving the retracting instruction, the controller responds to the retracting instruction and controls the power unit 515 of the first driving module 51 to drive the movable element 514 to move toward the optical axis image side through the transmission element 516 and the rotating element 513. The hinge 514 presses the connecting member 530 and drives the supporting frame 21 to move toward the optical axis side, and the supporting frame 21 compresses the elastic member 520 during the movement until the hinge 514 moves to the lowest position, at which time the lens assembly 2 returns to the retracted position.

Specific structures of the elastic member 520 include, but are not limited to, a spring plate, an elastic column, and the like. Materials include, but are not limited to, metals, plastics, rubbers, silicones, elastic composites, and the like. In this embodiment, the elastic member 520 is a spring.

Optionally, the number of the elastic members 520 is plural. The specific number of the elastic members 520 is not limited in the present application. The 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 by arranging the elastic pieces 520 at intervals, and the stability of the lens assembly 2 extending along the optical axis Z direction is improved.

Optionally, referring to fig. 14 and 15, the plurality of elastic elements 520 includes a first elastic element 522 and a second elastic element 524. The first elastic member 522 and the second elastic member 524 are springs for illustration.

Referring to fig. 14 and 15, the second driving module 52 further includes a first guiding rod 521. The first guide lever 521 is disposed along the optical axis Z direction. Optionally, the first guiding rod 521 penetrates through the bearing frame 21, and both ends of the first guiding rod 521 are fixed to the top plate 12 and the bottom plate 11, respectively. The carriage 21 is slidably coupled to the first guide bar 521. In other words, the first guide link 521 serves as a guide for the extension or retraction of the carriage 21. The first guide bar 521 can reduce eccentricity and inclination of the lens assembly 2 during extension and retraction, and improve the stability of extension and retraction of the lens assembly 2. The first elastic element 522 is sleeved on the first guiding rod 521. The first guide link 521 may also serve as a guide link for the first elastic member 522 to elastically expand and contract.

Further, referring to fig. 14 and 15, the second driving module 52 further includes a second guiding rod 523. The second elastic element 524 is disposed on the second guide rod 523. The second guide lever 523 is disposed in the optical axis Z direction. Optionally, the second guide bar 523 penetrates through the loading frame 21, and both ends of the second guide bar 523 are fixed to the top plate 12 and the bottom plate 11, respectively. The carriage 21 is slidably coupled to the second guide bar 523. In other words, the second guide bar 523 and the first guide bar 521 both guide the extension and retraction of the lens assembly 2.

In this embodiment, referring to fig. 16 and 17, the first guide bar 521 and the second guide bar 523 are distributed diagonally, so that the first elastic member 522 and the second elastic member 524 generate elastic thrusts at two diagonal positions of the supporting frame 21, thereby improving the stability of the lens assembly 2 on the X-Y plane, and reducing the problem that one side or one corner of the supporting frame 21 is subjected to the elastic thrusts to tilt the lens assembly 2 in the elastic process, thereby causing the problems of blocking and unsmooth stretching process.

Of course, in other embodiments, the first guide bar 521 and the second guide bar 523 may be located at opposite sides of the loading frame 21. For example, the first guide bar 521 and the second guide bar 523 are aligned in the X-axis direction. The first guide bar 521 and the second guide bar 523 are symmetrically arranged, and the first elastic member 522 and the second elastic member 524 generate elastic thrusts on two symmetrical sides of the bearing frame 21, so as to improve the stability of the lens assembly 2 on the X-Y plane.

In other embodiments, one guide bar is combined with one elastic member 520. The number of the guide rods and the elastic pieces 520 can be 3 groups, 4 groups and the like, and the guide rods and the elastic pieces 520 are uniformly arranged below the bearing frame 21, so that the lens assembly 2 is uniformly extended in an X-Y plane and further the lens assembly 2 is stably extended along the optical axis + Z direction, and the problems of blocking, unsmooth extension and the like are effectively reduced.

Further, referring to fig. 16 and 17, the first elastic element 522 is close to the connection between the first driving module 51 and the lens assembly 2 relative to the second elastic element 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 diagonal position 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 be deformed 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 retracts, so as to balance the problem of unbalanced force applied to the entire carrier 21 by the first driving module 51 acting on the first side 214 of the carrier 21 as much as possible, thereby improving the stability of the lens assembly 2 in extending or retracting.

Optionally, the diameter of the spring wire of the first elastic member 522 is larger than the diameter of the spring wire of the second elastic member 524; and/or the diameter of the coil of the first elastic member 522 is larger than the diameter of the coil of the second elastic member 524; and/or the number of turns of the first elastic member 522 is greater than the number of turns of the second elastic member 524, and so on, such that the spring constant of the first elastic member 522 is greater than the spring constant of the second elastic member 524.

Generally, during the retracting process of the lens assembly 2, the side of the lens assembly 2 close to the first driving module 51 is subjected to a relatively large pressing force in the optical axis-Z direction, and the side of the lens assembly 2 away from the first driving module 51 is subjected to a relatively small pressing force in the optical axis-Z direction. According to the lens assembly 2 retracting method, the first elastic piece 522 is designed to resist relatively large pressing force with a relatively large elastic coefficient, and the second elastic piece 524 resists relatively small pressing force with a relatively small elastic coefficient, so that the first elastic piece 522 and the second elastic piece 524 are compressed basically synchronously along the optical axis Z direction, the stability of the lens assembly 2 in the retracting process is improved, and the problems that the lens assembly 2 inclines on the side close to the first driving module 51 under the condition that the pressing force is relatively large, the retracting process is blocked and the like are solved.

Referring to fig. 14 and fig. 15, the power unit 515 is used to drive the movable element 514 to move toward the + Z direction of the optical axis to provide the extending space of the lens assembly 2, so that the driving force of the movable element 514, which needs to be provided by the power unit 515, does not need to be large, thereby saving energy. The driving force for extending the lens assembly 2 is provided by the compressed second driving module 52, and the plurality of elastic members 520 of the second driving module 52 are uniformly arranged to provide uniform pushing force to reduce eccentricity or tilt 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 against the elastic force to offset part or all of the impact force, thereby improving the impact resistance of the camera module 100.

In the second driving module 52 provided in the second embodiment, referring to fig. 23 and fig. 24, the second driving module 52 includes at least one pair of magnetic members 550 disposed oppositely. For example, there are two pairs of the magnetic members 550, one of the magnetic members 550 in each pair is fixed to the image side of the carriage 21, the other magnetic member 550 in each pair is fixed to the base plate 11, and the magnetic members 550 in each pair repel each other. In another embodiment, referring to fig. 25 and 26, there are two pairs of magnetic members 550, each pair of magnetic members 550 is disposed on the carriage 21 and the top plate 12, and the magnetic members 550 are attracted to each other. It should be noted that some of the magnetic members 550 block a portion 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 the magnetic members 550 are respectively located on the carriage 21 and the bottom plate 11, each pair of the magnetic members 550 is repulsive, wherein the other two pairs of the magnetic members 550 are respectively located on the carriage 21 and the top plate 12, and each pair of the magnetic members 550 is attractive.

For example, the pair of magnetic members 550 are disposed on the image side of the carriage 21 and the bottom plate 11, when the pair of magnetic members 550 are disposed on the image side of the carriage 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 disposed on the object side of the loading frame 21 and the top plate 12, an attractive force is generated between the pair of magnetic members 550.

The driving force provided by the second driving module 52 to the lens assembly 2 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-described embodiments. The main differences from the above embodiments are: the first elastic member 522 elastically abutted between the carriage 21 and the bottom plate 11 is replaced by 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, etc. The second resilient member 524 between the carriage 21 and the base plate 11 is also replaced by a pair of opposing and repelling magnets. Alternatively, the first resilient member 522 between the carrier 21 and the top plate 12 may be replaced by a pair of opposing and repelling magnets, and the second resilient member 524 between the carrier 21 and the top plate may be replaced by a pair of opposing and repelling 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 retracted within 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 a magnetic force, the space between the pair of repulsive magnetic members 550 is a compressible magnetic space. When the lens assembly 2 stretches out to accommodate the cavity 1a and receives an impact force, the lens assembly 2 compresses the compressible magnetic space by overcoming the magnetic repulsion force so as to offset part or all of the impact force, thereby improving the impact resistance of the camera module 100, effectively protecting the lens assembly 2 and improving the falling 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 elements 520 and at least one pair of magnetic elements 550 disposed oppositely. Specifically, two magnetic members of a pair of magnetic members 550 are respectively disposed between the loading frame 21 and the top plate 12, 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 loading frame 21 and the top plate 12 and/or between the loading frame 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 multiple, and the elastic coefficient (or number) of the elastic members 520 close to the first driving module 51 is larger than the elastic coefficient (or number) of the elastic members 520 far away from the first driving module 51, so that the driving force generated by the first driving module 51 to one side of the bearing frame 21 can be balanced, and the stability of the extension and retraction of the lens assembly 2 can be improved.

For example, the pair of magnetic members 550 are respectively disposed on the image side of the carriage 21 and the bottom plate 11. The pair of magnetic members 550 magnetically repel each other. The elastic member 520 elastically contacts between the image side of the carriage 21 and the base plate 11. Optionally, the resilient member 520 is compressed. By arranging the pair of magnetic members 550 with the elastic members 520 therein, the magnetic members 550 generate a driving force towards the optical axis side for the carrier frame 21, the elastic members 520 also generate a driving force towards the optical axis side for the carrier frame 21, the magnetic members 550 and the elastic members 520 drive the carrier frame 21 to extend together, and when the lens assembly 2 retracts, the carrier frame 21 overcomes the acting forces of the magnetic members 550 and the elastic members 520, so that the damping of the lens assembly 2 during retraction can be improved, and the lens assembly 2 can be retracted smoothly. Of course, in other embodiments, the elastic member 520 may also be in a stretched state, and when the magnetic member 550 generates a driving force towards the optical axis side to the carrier 21, the elastic member 520 may slow the driving force of the magnetic member 550 to the carrier 21, so as to damp the extension of the lens assembly 2, so as to make the lens assembly 2 extend smoothly.

Further, the top plate 12 and the bottom plate 11 are provided with guide rods, the guide rods penetrate through corners (or edges) of the bearing frame 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 guiding in the optical axis direction for the movement of the pair of magnetic members 550, the elastic members 520 and the bearing frame 21.

Referring to fig. 32 to 34, two magnetic members of the pair of magnetic members 550 are respectively disposed between the loading frame 21 and the top plate 12. The pair of magnetic members 550 are magnetically attracted to each other. The elastic member 520 elastically abuts 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 multiple, and the elastic coefficient (or number) of the elastic members 520 close to the first driving module 51 is larger than the elastic coefficient (or number) of the elastic members 520 far away from the first driving module 51, so that the driving force generated by the first driving module 51 to one side of the bearing frame 21 can be balanced, and the stability of the extension and retraction of the lens assembly 2 can be improved.

Referring to fig. 35 to 37, two magnetic members of one pair of magnetic members 550 are respectively disposed between the supporting frame 21 and the top plate 12 and are magnetically attracted to each other, and two magnetic members of the other pair of magnetic members 550 are respectively disposed between the supporting frame 21 and the bottom plate 11 and are magnetically repelled to each other. The elastic member 520 elastically abuts 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 multiple, and the elastic coefficient (or number) of the elastic members 520 close to the first driving module 51 is larger than the elastic coefficient (or number) of the elastic members 520 far away from the first driving module 51, so that the driving force generated by the first driving module 51 to one side of the bearing frame 21 can be balanced, and the stability of the extension and retraction of the lens assembly 2 can be improved.

In this 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), the controller is electrically connected to the power unit 515, the controller controls a rotating shaft of the power unit 515 to rotate, the rotating 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 the rotating rod 513 rotates around the Z axis to drive the moving member 514 to move up and down along the rotating rod 513 because the moving member 514 is in threaded connection with the rotating rod 513, that is, the moving member 514 moves along the Z axis along with the rotating shaft of the rotating rod 513.

The controller responds to the extension instruction to control the power unit 515 to drive the movable member 514 to move along the object side of the optical axis through the transmission member 516 and the rotating rod 513, so as to release the movable space of the extension movement of the lens assembly 2. The second driving module 52 pushes the lens component 2 to extend out of the receiving cavity 1a, the supporting frame 21 pushes the connecting member 530 to move along with the movable member 514 until reaching the maximum extending position, the power unit 515 stops driving the movable member 514 to move, the connecting member 530 stops moving, and the lens component 2 is limited by the connecting member 530 to reach 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 at this time, the camera module 100 is in an operating state.

The controller controls the power unit 515 to rotate reversely in response to the retracting instruction, the power unit 515 drives the movable element 514 to move along the optical axis image side through the transmission element 516 and the rotation rod 513, the movable element 514 pushes the connecting element 530 to move towards the optical axis image side, the second driving module 52 includes an elastic element 520 or a pair of magnetic elements 550 having a compressible space, the compressible space inside the second driving module 52 is compressed to provide a moving space for the lens assembly 2 to move towards the optical axis image side, and the movable element 514 drives the lens assembly 2 to retract into the accommodating cavity 1a through the connecting element 530 until the lens assembly 2 is in the retracting state.

The position and the direction of the first driving module 51 relative to the lens assembly 2 are not limited in the present application, and the first driving module 51 may be adjusted and determined according to actual conditions, and may be in any direction around the lens assembly 2.

In the camera module 100 provided in the embodiment of the present application, by providing the second driving module 52 and the first driving module 51, the first driving module 51 is configured to provide an extending space for the lens assembly 2 through the movement of the moving member 514, that is, after the moving member 514 moves toward the optical axis + Z direction, the lens assembly 2 has an extendable space so as to extend under the pushing of the second driving module 52, and the lens assembly 2 extends or retracts under the clamping force of the second driving module 52 and the first driving module 51 along the extending and retracting direction, so as to improve the extending and retracting smoothness and the extending controllability of the lens assembly 2 in the extending and retracting process; for the camera module 100 and the electronic device 1000 carrying the lens assembly 2, the lens assembly 2 is set in the extended state so that the lens assembly 2 interacts with a user or an external environment, and the lens assembly 2 is set in the retracted state so that the hiding performance of the lens assembly 2 is improved, the portability of the electronic device 1000 is improved, and the internal space of the electronic device 1000 is also saved.

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

The present application will be described with reference to the following drawings, which illustrate a specific structure of the second embodiment in which the first driving module 51 drives the lens assembly 2 to extend in a single pass. The structure of the first driving module 51 provided in the present embodiment is basically the same as the structure of the first driving module 51 provided in the first embodiment, and the main differences are that: referring to fig. 38 and 39, the movable member 514 has an abutting force against a side of the lens assembly 2 facing the photosensitive element 3. By designing the moving element 514 to generate a contact force on the optical axis image side of the lens assembly 2, the moving element 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 of the movable element 514 movably connected to the lens assembly 2, the movable element 514 acts on the image side of the supporting frame 21, the movable element 514 moves along the + Z direction of the optical axis, and the movable element 514 has a contact force against one side of the lens assembly 2 facing the photosensitive element 3, so as to push the lens assembly 2 out of the accommodating cavity 1a, so that the lens assembly 2 is in the 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 receiving 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 element 3. I.e., movable member 514 is positioned image-wise of first end 530a of connecting member 530. The movable member 514 moves along the + Z direction, and pushes the connecting member 530 to move toward the object side, so as to push the lens assembly 2 out.

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. The third direction is an object-side direction (+ Z axis) and the fourth direction is an image-side direction (-Z axis).

The second driving module 52 is configured to drive the lens assembly 2 to move in the fourth direction when the first driving module 51 provides a movement space, and to provide 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 the present embodiment, the structure of the second driving module 52 is substantially the same as the structure of the second driving module 52 in the previous embodiment, and the main differences are:

the elastic member 520 of the present embodiment is in a different state from the elastic member 520 of the previous embodiment. The elastic member 520 generates a force in the optical axis image side direction on the carriage 21. 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 provided 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 can also refer to the embodiment of the first driving module 51 provided in the first embodiment.

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

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

In the present embodiment, the first driving module 51 is arranged to drive the lens assembly 2 to extend in a single way, and the second driving module 52 is arranged to drive the lens assembly 2 to retract in a single way, because in the extending process, the movable member 514 drives the supporting frame 21 to extend through the connecting member 530, 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, 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, so as to realize that different focal lengths exist between the lens assembly 2 and the photosensitive assembly 3; in addition, the driving force of the movable member 514 on the extension of the lens assembly 2 is a hard force, which can improve the stability of the extended state of the lens assembly 2.

When the second driving module 52 includes at least one pair of magnetic members, the acting force between the pair of magnetic members 550 in the present embodiment is different from the acting force between the pair of magnetic members 550 in the previous embodiment. Referring to fig. 28 to 37, the pair of magnetic members 550 generate a force in the optical axis image side direction on the carriage 21. For example, when the pair of magnetic members 550 is disposed between the image side of the carriage 21 and the bottom plate 11, the pair of magnetic members 550 are magnetically attracted to each other. When the pair of magnetic members 550 is disposed between the object side of the loading frame 21 and the top plate 12, the pair of magnetic members 550 are magnetically repelled. Of course, the position of the pair of magnetic members 550 can also refer to the implementation manner in the first driving module 51 provided in the first embodiment.

In addition, the arrangement of the guide rod, the positions of the plurality of elastic members 520, the positions of the plurality of pairs of magnetic members 550, and the like in the present embodiment can be referred to the illustration in the previous embodiment.

The above is an embodiment in which the first driving module 51 includes a motor, a rotating lever 513, and a nut. Of course, in other embodiments, the power unit 515 and the movable member 514 of the first driving 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, 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 loading frame 21, and repel each other. The first driving module 51 generates a driving force toward the optical axis image side with respect to the carriage 21. The magnetic member 550 fixed to the top plate 12 is a power unit 515, and the magnetic member 550 fixed to the carriage 21 is a movable member 514. The power unit 515 may be an electromagnet, and the moving 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 element 520 and guide rods (521, 523). Both ends of the elastic member 520 elastically contact between the base plate 11 and the image side of the carrier 21, and the elastic member 520 is in a compressed state and generates a driving force toward the optical axis side with respect to the carrier 21. The number of pairs of the magnetic members 550 and the number of the elastic members 520 may be plural, and the pairs of the magnetic members 550 and the elastic members 520 are uniformly distributed in the X-Y plane of the carrier 21, so as to improve the extending and retracting smoothness of the lens assembly 2.

The controller responds to the extension instruction to control the magnetic repulsion force generated by the power unit 515 to the movable element 514 to decrease, the magnetic repulsion force is smaller than the elastic pushing force of the elastic element 520, and the elastic element 520 drives the carrier frame 21 to move toward the optical axis side, so as to extend the lens assembly 2 until the lens assembly 2 is located at the extension position. The controller responds to the retracting command to control the power unit 515 to generate a relatively large magnetic repulsive force to the movable element 514, where the magnetic repulsive force is larger than the elastic pushing force of the elastic element 520, so as to drive the bearing frame 21 to move toward the optical axis image side, thereby retracting the lens assembly 2 until the lens assembly 2 is in the retracting 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 optical axis object side to the carrier 21. Both ends of the elastic member 520 elastically contact between the base plate 11 and the image side of the carriage 21, and the elastic member 520 is in a stretched state and generates a driving force toward the image side of the optical axis with respect to the carriage 21.

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

Referring to fig. 41, the pair of magnetic members 550 of the first driving module 51 are respectively located between the bottom plate 11 and the image side of the supporting frame 21, and are magnetically attracted to each other, so as to generate a force towards the image side of the optical axis for driving the lens assembly 2 to retract. Both ends of the elastic member 520 of the second driving module 52 elastically abut against the top plate 12 and the object side of the carrier 21, respectively, and the elastic member 520 is in a stretched state, and generates an acting force toward the optical axis object side direction on the lens assembly 2 to drive the lens assembly 2 to extend. The controller controls the magnitude of the magnetic force between the pair of magnetic members 550 of the first driving module 51 according to the extension command or the retraction command to control the extension or retraction of the lens assembly 2.

Of course, in other embodiments, the pair of magnetic members 550 are respectively located between the bottom plate 11 and the image side of the carriage 21, and the magnetism is repelled to generate a force toward the optical axis object side on the lens assembly 2. Both ends of the elastic member 520 elastically contact between the top plate 12 and the object side of the carrier 21, and the elastic member 520 is in a compressed state and generates a driving force toward the optical axis side to the carrier 21.

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

Referring to fig. 42, one pair of magnetic members 550 of the first driving module 51 is disposed between the bottom plate 11 and the image side of the supporting frame 21, and the other pair of magnetic members 550 is disposed between the top plate 12 and the object side of the supporting frame 21. The pair of magnetic members 550 disposed between the bottom plate 11 and the carrier 21 are magnetically attracted to each other, and the other pair of magnetic members 550 disposed between the top plate 12 and the object side of the carrier 21 are magnetically repelled to each other, so that the first driving module 51 generates a driving force toward the image side of the optical axis with respect to the carrier 21. The elastic member 520 of the second driving module 52 generates a driving force toward the optical axis side 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 optical axis image side with respect to the carrier frame 21, and the first driving module 51 generates a driving force toward the optical axis object side with respect to the carrier frame 21.

The elastic member 520 of the second driving module 52 can be disposed in the manner of referring to 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, and 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 element 520 of the second driving module 52 is disposed between the top plate 12 and the object side of the carrier frame 21 and is in a stretched state, and the other elastic element 520 is disposed between the bottom plate 11 and the image side of the carrier frame 21 and is in a compressed state, and the second driving module 52 generates a driving force toward the optical axis side with respect to the carrier frame 21.

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 this application. The magnetic member 550 of the first driving module 51 acts on the carriage 21 in a direction opposite to the resilient member 520 of the second driving module 52 acting on the carriage 21.

In the above embodiment, the first driving module 51 and the second driving module 52 cooperate 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 following describes a structure of a first driving module 51 provided in a fourth embodiment of the present invention with reference to the drawings.

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

Optionally, the power unit 515 is a motor, and the movable member 514 is a nut. The first drive module 51 further comprises a rotation rod 513, a transmission 516. The rotating rod 513 is a lead 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, and is not described herein again.

Alternatively, referring to fig. 43 and 44, the power unit 515 is a motor, and a rotation axis of the power unit 515 is along the Y-axis direction. The first drive module 51 further comprises a worm gear 534, a worm 535, a turning rod 513, a transmission 516. The rotating shaft of the power unit 515 is disposed along the Y-axis direction to reduce the thickness of the first driving module 51, and thus the thickness of the camera module 100. The worm 535 is also disposed along the Y-axis direction. One end of the worm 535 is fixedly connected with a rotating shaft of the power unit 515, when the power unit 515 rotates, the worm 535 rotates along with the rotating shaft, and the worm wheel 534 converts the rotation of the worm 535 around the Y-axis direction into the rotation around the optical axis Z direction. The transmission member 516 includes a plurality of intermeshing gears. The structure of the transmission member 516 in the present embodiment can refer to the structure of the transmission member 516 in the first drive 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 screwed with the rotating rod 513. The power unit 515 outputs rotation, the worm 535 on the power unit 515 drives the worm gear 534 to rotate, a transmission piece 516 is arranged on the shaft of the worm gear 534 and is transmitted to the rotating rod 513 through a series of transmission pieces 516, and the rotating rod 513 is pushed to rotate. As rotating lever 513 rotates about the Z-axis, moveable 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 by this embodiment is placed along the Y-axis direction, and the shape and the contour size of the whole structure can be adjusted. The rotation shaft of the power unit 515 may be disposed along the Y-axis direction, that is, the power unit 515 is disposed transversely, and the rotation shaft is converted into rotation around the optical axis Z direction by cooperating with the worm gear 534 and the worm 535, and then the transmission is transmitted to the movable member 514 by cooperating with the transmission member 516. When the power unit 515 is transversely placed, the thickness of the first driving module 51 in the direction of the optical axis Z can be reduced, so that the outer contour of the camera module 100 is gradually reduced in thickness, 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), the structural design of the gears in the synchronous adjustment transmission member 516 can realize the gradual reduction of the thickness of the outer contour, and the thickness is reduced in a step manner. The power unit 515 provided by this embodiment is laterally disposed, and a reduction gear scheme of the worm gear 534 and the worm 535 can be adopted, so as to realize a large reduction ratio and a self-locking capability, and when the extended lens assembly 2 is pressed reversely, the lens assembly 2 does not retract.

Referring to fig. 45 to 47, in a first driving module 51 provided in a fifth embodiment, a power unit 515 is disposed opposite to or attached to a movable member 514. At least one of power unit 515 and moving member 514 is an electromagnet. The power unit 515 and the movable member 514 have a magnetic attraction force or a magnetic repulsion force therebetween. 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 acting force provided by the first driving module 51 to the lens assembly 2 is a magnetic force. The power unit 515 is an electromagnet. The moving member 514 is an electromagnet, a permanent magnet, or a magnetizer. The movable element 514 may be disposed on an image side or an object side of the supporting frame 21, and the power unit 515 and the movable element 514 are disposed opposite to each other. For example, the movable element 514 is disposed on the side of the carrier 21, i.e. the movable element 514 and the lens assembly 2 are both disposed on the same side of the carrier 21. The power unit 515 is fixed to the top plate 12 and disposed opposite to the movable member 514. The power unit 515 is an electromagnet, such as a solenoid. The electronic device 1000 also includes a controller.
