Description

Technical Field

[0001] This invention relates to optical imaging devices, and more particularly to an optical lens, a camera module, an electronic device, and a method for assembling the optical lens. Background Technology

[0002] In recent years, small camera modules equipped with imaging elements such as CCD (Charge Coupled Device) or CMOS (Complementary Metal-Oxide Semiconductor) image sensors have been widely used in portable electronic devices (e.g., smartphones), and the market demands increasingly higher image quality and smaller size for camera modules in portable electronic devices. Existing camera modules include a photosensitive element and an optical lens disposed on the photosensitive element. The optical lens typically includes 3-5 lenses arranged sequentially along the optical axis. Incident light is focused as it passes through these lenses and reaches the image sensor of the photosensitive element to form an image. For zoom camera modules, the optical lens needs to be drivably mounted on a driver (e.g., a voice coil motor). The driver achieves focusing of the camera module by driving the overall movement of the optical lens. Although zoom camera modules have the advantage of better image quality, their disadvantages are as follows: First, the driver setup increases the size of the camera module, making it unsuitable for use on the front of portable electronic devices that aim for thinness and lightness. Therefore, front-facing camera modules of portable electronic devices on the market all use fixed-focus camera modules, which limits their imaging capabilities. Second, the driver achieves focusing of the camera module by driving the overall movement of the optical lens. This changes the overall optical length of the optical lens, which is not conducive to the miniaturization of the camera module. Furthermore, when the camera module is configured in a portable electronic device, especially as a front-facing camera module, the internal space of the portable electronic device needs to be reserved for the movement of the optical lens, which prevents the thickness of the portable electronic device from being reduced. Summary of the Invention

[0065] Appendix Figures 1A to 1I The assembly process of an optical lens 100 according to a preferred embodiment of the present invention is shown, with appended details. Figure 2A and Figure 2B The disassembled state of the optical lens 100 is shown.

[0066] The optical lens 100 includes an object-side lens group 10, a focusing lens group 20, an image-side lens group 30, and a housing 40. The object-side lens group 10 is mounted on the housing 40 and located outside the housing 40 to allow the optical lens 100 to adopt a "small head" design. The focusing lens group 20 is drivably disposed inside the housing 40, and the image-side lens group 30 is fixedly disposed inside the housing 40. The object-side lens group 10, the focusing lens group 20, and the image-side lens group 30 are arranged coaxially, thus forming the general appearance of the optical lens 100 and allowing the optical lens 100 to incorporate focusing functionality. When the focusing lens group 20 is driven to move along the optical axis of the optical lens 100, the focal position of the optical lens 100 can be adjusted to achieve focusing.

[0067] Specifically, the outer casing 40 further includes a main casing 41 and a bottom casing 42 mounted on the bottom side of the main casing 41, and the outer casing 40 has a casing space 43 formed between the main casing 41 and the bottom casing 42, wherein the main casing 41 forms a top central opening 411 communicating with the casing space 43, and the bottom casing 42 forms a bottom central opening 421 communicating with the casing space 43.

[0068] The object-side lens group 10 is attached to the outside of the main housing 41 of the housing 40, and the top center opening 411 of the main housing 41 corresponds to the object-side lens group 10, so that incident light passing through the object-side lens group 10 is allowed to enter the interior of the housing 40 through the top center opening 411 of the main housing 41.

[0069] Further, the object-side lens group 10 includes an object-side lens barrel 11 and at least one object-side lens 12 mounted on the object-side lens barrel 11. The object-side lens barrel 11 is attached to the outside of the main housing 41, and the top center opening 411 of the main housing 41 corresponds to the object-side lens 12. Thus, the object-side lens group 10 is attached to the outer housing 40. Preferably, the bottom side of the object-side lens barrel 11 is attached to the outside of the main housing 41. For example, the bottom side of the object-side lens barrel 11 can be attached to the outside of the main housing 41 using adhesive. In this case, the adhesive can compensate for the tilt of the object-side lens group 10.

[0070] Preferably, the main housing 41 has at least one flange 412 for defining the top central opening 411 of the main housing 41, wherein the object-side lens barrel 11 is attached to the flange 412 of the main housing 41 to raise the position of the object-side lens group 10 by the flange 412.

[0071] Furthermore, the main housing 41 has a mounting channel 413 defined by the flange 412 to allow the mounting channel 413 to connect the top central opening 411 and the housing space 43, wherein the focusing lens group 20 is allowed to be mounted to the housing space 43 of the outer housing 40 via the mounting channel 413 of the main housing 41.

[0072] It is understandable that, in order to ensure that the focusing lens group 20 is smoothly assembled into the housing space 43 of the outer shell 40 via the assembly channel 413 of the main housing 41, the height of the assembly channel 413 of the main housing 41 is slightly larger than the thickness of the focusing lens group 20. This prevents the main housing 41 from scraping against the focusing lens group 20 during the assembly process. It is also understandable that the height of the assembly channel 413 of the main housing 41 is limited by the height of the flange 412; therefore, the design of the height of the flange 412 of the main housing 41 is determined by the thickness of the focusing lens group 20.

[0073] Preferably, the main housing 41 has two flanges 412, which are disposed opposite to each other on both sides of the top central opening 411, so that the main housing 41 can form two opposing assembly channels 413 between the two flanges 412.

[0074] The focusing lens group 20 is drivably disposed in a suspended manner within the housing space 43 of the housing 40, allowing the housing 40 to surround and protect the focusing lens group 20. It is worth noting that the specific implementation structure of the focusing lens group 20 being drivably disposed in a suspended manner within the housing space 43 of the housing 40 will be further disclosed in the subsequent description.

[0075] Preferably, the diameter of the object-side lens group 10 is larger than the diameter of the focusing lens group 20, so that, while ensuring that the focusing lens group 20 is allowed to be assembled into the housing space 43 of the housing 40 via the assembly channel 413 of the main housing 41, the object-side lens barrel 11 of the object-side lens group 10 can be attached to the flange 412 of the main housing 41.

[0076] The image-side lens group 30 is mounted on the main housing 41 to fix the image-side lens group 30 in the housing space 43 of the outer housing 40. Specifically, refer to the attached drawing. Figure 2A and Figure 2BThe main housing 41 has at least one mounting arm 414 located in the housing space 43 of the outer housing 40, wherein the image-side lens group 30 is mounted to the main housing 41 by means of mounting the mounting arm 414. Optionally, in other examples of the optical lens 100 of the present invention, the image-side lens group 30 may be mounted to the bottom housing 42 so that the bottom housing 42 holds the image-side lens group 30 in the housing space 43 of the outer housing 40.

[0077] Furthermore, the image-side lens group 30 includes an image-side lens barrel 31 and at least one image-side lens 32 mounted on the image-side lens barrel 31, wherein the image-side lens barrel 31 is mounted on the mounting arm 414 of the main housing 41 to fix the image-side lens group 30 in the housing space 43 of the housing 40.

[0078] It is worth mentioning that the mounting method of the image-side lens barrel 31 of the image-side lens group 30 and the mounting arm 414 of the main housing 41 is not limited in the optical lens 100 of the present invention. For example, in this specific example of the optical lens 100 of the present invention, refer to the attached... Figure 2A and Figure 2B The mounting arm 414 of the main housing 41 has at least one slot 4141, and correspondingly, the image-side lens barrel 31 of the image-side lens group 30 has at least one protrusion 311, wherein the protrusion 311 of the image-side lens barrel 31 is engaged with the slot 4141 of the mounting arm 414 to mount the image-side lens group 30 to the main housing 41. Optionally, in other specific examples of the optical lens 100 of the present invention, the slot 4141 may be provided on the image-side lens barrel 31, and correspondingly, the protrusion 311 may be provided on the mounting arm 414, such that the protrusion 311 of the mounting arm 414 can be engaged with the slot 4141 of the image-side lens barrel 31 to mount the image-side lens group 30 to the main housing 41.

[0079] Continue to refer to the appendix Figures 1A to 2B The optical lens 100 further includes a drive unit 50 for suspending and holding the focusing lens group 20 in the housing space 43 of the housing 40 and for driving the focusing lens group 20 to move along the optical axis of the optical lens 100 to achieve focusing.

[0080] Specifically, the driving unit 50 includes a fixing part 51, a supporting part 52, and a driving part 53 for driving the supporting part 52 to move relative to the fixing part 51 along the optical axis of the optical lens 100. The fixing part 51 is fixedly disposed on the housing 40. The supporting part 52 has a supporting outer side 5201 and a supporting inner side 5202 corresponding to the supporting outer side 5201. The supporting outer side 5201 of the supporting part 52 extends outward to a position adjacent to the fixing part 51, and the supporting inner side 5202 of the supporting part 52 extends inward above the image-side lens group 30, allowing the focusing lens group 20 mounted on the supporting inner side 5202 of the supporting part 52 to be held in a suspended manner above the image-side lens group 30. When the driving part 53 drives the supporting part 52 to move, the supporting part 52 drives the focusing lens group 20 to move synchronously to achieve focusing.

[0081] In the appendix Figures 1A to 2B In this specific example of the optical lens 100 shown, the fixing part 51 is fixedly disposed on the main housing 41 of the housing 40. Alternatively, in other examples of the optical lens 100 of the present invention, the fixing part 51 may be fixedly disposed on the bottom housing 42 of the housing 40, or the fixing part 51 and the main housing 41 may be an integral structure, or the fixing part 51 and the bottom housing 42 may be an integral structure.

[0082] Continue to refer to the appendix Figures 1A to 2B The driving unit 50 further includes at least one spring 54, wherein the outer side of the spring 54 extends outward to be connected to the fixing part 51, and the inner side of the spring 54 extends inward to be connected to the supporting part 52. Thus, when the driving part 53 does not drive the supporting part 52, the fixing part 51, the supporting part 52 and the spring 54 keep the focusing lens group 20 in a relatively stable state. When the driving part 53 drives the supporting part 52, the spring 54 can deform.

[0083] It is worth mentioning that the number of spring pieces 54 is not limited in the optical lens 100 of the present invention. For example, the number of spring pieces 54 can be one, with the outer and inner sides of the spring piece 54 respectively connected to the upper side of the fixing part 51 and the upper side of the supporting part 52, or the inner and outer sides of the spring piece 54 respectively connected to the lower side of the fixing part 51 and the lower side of the supporting part 52; or, the number of spring pieces 54 can be two, with the outer and inner sides of one spring piece 54 respectively connected to the upper side of the fixing part 51 and the upper side of the supporting part 52, and the outer and inner sides of the other spring piece 54 respectively connected to the lower side of the fixing part 51 and the lower side of the supporting part 52.

[0084] Optionally, in other examples of the optical lens 100 of the present invention, the drive unit 50 may utilize at least one ball bearing instead of the spring 54, so that the focusing lens group 20 is held in a suspended manner within the housing space 43 of the housing 40. Specifically, the ball bearing is held between the fixing part 51 and the supporting part 52. When the drive part 53 does not drive the supporting part 52, the fixing part 51, the supporting part 52, and the ball bearing keep the focusing lens group 20 in a relatively stable state. When the drive part 53 drives the supporting part 52, the ball bearing can roll, making the movement of the supporting part 52 smoother. Specifically, the fixing part 51 is provided with at least one first groove for receiving a portion of the ball bearing, and correspondingly, the supporting part 52 is provided with at least one second groove for receiving a portion of the ball bearing, thus reliably holding the ball bearing between the fixing part 51 and the supporting part 52 and avoiding direct contact between the supporting part 52 and the fixing part 51.

[0085] Continue to refer to the appendix Figures 1A to 2B The driving unit 53 includes at least one magnet 531 and at least one coil 532. The magnet 531 is disposed on the fixing part 51, and the coil 532 is disposed on the outer side 5201 of the bearing part 52. The positions of the magnet 531 and the coil 532 correspond to each other. When the coil 532 is powered, the magnetic field generated by the coil 532 interacts with the magnet 531 to drive the bearing part 52 to move, thereby driving the focusing lens group 20 to move and achieve focusing.

[0086] Preferably, the fixing part 51 is annular and located outside the focusing lens group 20. The driving part 53 includes two magnets 531, which are arranged opposite each other on opposite sides of the fixing part 51, thus holding the two magnets 531 oppositely to each other outside the focusing lens group 20. The bearing outer side 5201 of the supporting part 52 is annular and located outside the focusing lens group 20. The driving part 53 includes a coil 532 that winds around the bearing outer side 5201 of the supporting part 52, thus the coil 532 is annular and located outside the focusing lens group 20. With this structure, when the coil 532 is powered, the magnetic field generated by the annular coil 532 and the two oppositely arranged magnets 531 interact to drive the supporting part 52 evenly, preventing the supporting part 52 from tilting during movement and thus ensuring the optical performance of the optical lens 100.

[0087] Preferably, the support portion 52 forms an annular winding groove 5203 on the outer support side 5201, wherein the coil 532 is wound around the winding groove 5203 of the support portion 52 to ensure that the coil 532 is disposed on the outer support side 5201 of the support portion 52. Furthermore, by allowing the coil 532 to be wound around the winding groove 5203 of the support portion 52, the coil 532 can be prevented from protruding from the sidewall of the outer support side 5201 of the support portion 52, which helps to reduce the length and width dimensions of the optical lens 100.

[0088] Alternatively, in other examples of the optical lens 100 of the present invention, the driving part 53 may include three or more magnets 531, for example, the driving part 53 may include four magnets 531, which are arranged on the fixing part 51 in a manner that is spaced apart from each other and surrounds the focusing lens group 20.

[0089] It is worth mentioning that the assembly method of the magnet 531 of the driving part 53 and the fixing part 51 is not limited in the optical lens 100 of the present invention. For example, the magnet 531 can be pasted to the inner wall of the fixing part 51 to fix the magnet 531 to the fixing part 51, or the fixing part 51 is provided with at least one mounting groove 511 for mounting the magnet 531 to fix the magnet 531 to the fixing part 51.

[0090] Preferably, refer to the appendix. Figures 1A to 2B The fixing part 51 surrounds the image-side lens group 30, so that the two magnets 531 are arranged opposite each other on opposite sides of the image-side lens group 30. Correspondingly, the height position of the bearing outer side 5201 of the bearing part 52 is lower than the height position of the bearing inner side 5202. In this way, while the bearing part 52 supports the focusing lens group 20 on the upper side of the image-side lens group 30, the coil 532 wound around the bearing outer side 5201 of the bearing part 52 can be wound around the image-side lens group 30. In this way, the coil 532 of the driving unit 50 can be lowered to reduce the height dimension of the optical lens 100.

[0091] Specifically, the support portion 52 further includes a driven ring 521, a support ring 522, and at least one extension arm 523 extending between the driven ring 521 and the support ring 522, wherein the driven ring 521 forms the support outer side 5201 of the support portion 52 to allow the coil 532 to be wound around the driven ring 521, wherein the support ring 522 forms the support inner side 5202 of the support portion 52 for mounting the focusing lens group 20, wherein at least a portion of the extension arm 523 is inclined to allow the height position of the support outer side 5201 of the support portion 52 to be lower than the height position of the support inner side 5202.

[0092] Preferably, the extension arm 523 of the support portion 52 corresponds to the assembly channel 413 of the main housing 41. When the support portion 52 is driven, at least a portion of the extension arm 523 of the support portion 52 can move to the assembly channel 413 of the main housing 41 to avoid the extension arm 523 from touching the main housing 41, thereby increasing the travel range of the support portion 52 and thus increasing the travel range of the focusing lens group 20. In other words, the assembly channel 413 of the main housing 41 can form a clearance space to avoid the extension arm 523 of the support portion 52, thereby increasing the travel range of the focusing lens group 20. Preferably, the width of the assembly channel 413 of the main housing 41 is slightly larger than the width of the extension arm 523 of the support portion 52 to avoid the extension arm 523 scraping against the main housing 41 and to ensure the reliability of the optical lens 100.

[0093] Preferably, the main housing 41 further has at least one movable channel 415 communicating with opposite sides of the mounting arm 414, wherein the extension arm 523 of the support portion 52 is movably held in the movable channel 415 of the main housing 41, thereby allowing the driven ring 521 and the support ring 522 of the support portion 52 to be held respectively on opposite sides of the mounting arm 414. Preferably, the width of the movable channel 415 of the main housing 41 is greater than the width of the extension arm 523 of the support portion 52, thereby preventing the extension arm 523 from scraping against the mounting arm 414 of the main housing 41 when the drive portion 53 drives the support portion 52 to move.

[0094] More specifically, the support portion 52 includes two extension arms 523 that connect the driven ring 521 and the support ring 522 in a mutually symmetrical manner. Correspondingly, the main housing 41 has two movable channels 415, wherein each extension arm 523 of the support portion 52 is movably mounted in each of the movable channels 415 of the main housing 41.

[0095] Continue to refer to the appendix Figures 1A to 2B The extension arm 523 of the support portion 52 has a lower horizontal extension portion 5231, an upper horizontal extension portion 5232, and an inclined extension portion 5233. The lower horizontal extension portion 5231 extends inward integrally from the driven ring 521, and the upper horizontal extension portion 5232 extends outward integrally from the support ring 522. The opposite ends of the inclined extension portion 5233 extend to and are connected to the lower horizontal extension portion 5231 and the upper horizontal extension portion 5232, respectively. Thus, the height position of the driven ring 521 of the support portion 52 is lower than the height position of the support ring 522, causing the coil 532 of the drive portion 53 to sink, which helps to reduce the height dimension of the optical lens 100.

[0096] In an optional example of the optical lens 100 of the present invention, the extension arm 523 of the support portion 52 is composed of the lower horizontal extension portion 5231 and the inclined extension portion 5233, wherein the lower horizontal extension portion 5231 extends integrally inward from the driven ring 521, and the opposite ends of the inclined extension portion 5233 extend to and are connected to the lower horizontal extension portion 5231 and the support ring 522, respectively.

[0097] In another alternative example of the optical lens 100 of the present invention, the extension arm 523 of the support portion 52 is composed of the upper horizontal extension portion 5232 and the inclined extension portion 5233, wherein the upper horizontal extension portion 5232 extends integrally outward from the support ring 522, and the opposite ends of the inclined extension portion 5233 extend to and are connected to the upper horizontal extension portion 5232 and the driven ring 521, respectively.

[0098] In another alternative example of the optical lens 100 of the present invention, the extension arm 523 of the support portion 52 is inclined as a whole, that is, the opposite ends of the extension arm 523 extend to and are connected to the driven ring 521 and the support ring 522 respectively in such an inclined manner as the extension arm 523 is inclined as a whole.

[0099] Furthermore, the drive unit 50 includes a carrier 55, wherein the carrier 55 surrounds the focusing lens group 20, and the carrier 55 is mounted on the carrier ring 522 of the carrier portion 52, and the focusing lens group 20 is fixedly mounted on the carrier portion 52 by the carrier 55.

[0100] Furthermore, the optical lens 100 includes a cover 60, wherein the bottom side of the cover 60 extends to and is attached to the main housing 41, and the inner side of the cover 60 extends to and is attached to the object-side lens barrel 11 of the object-side lens group 10, so as to allow the cover 60 to close the assembly channel 413 of the main housing 41, thereby preventing dust and other contaminants from entering the housing space 43 of the housing 40 through the assembly channel 413 of the main housing 41 and contaminating the focusing lens group 20 and the image-side lens group 30.

[0101] Appendix Figures 1A to 1I The assembly process of the optical lens 100 shown includes the following stages.

[0102] Reference Appendix Figure 1A A standard lens group 300 is pre-fixed to the support ring 522 of the support part 52.

[0103] Reference Appendix Figure 1B The support ring 52 and the fixing part 51 are connected by the spring piece 54, wherein the fixing part 51 is installed on the main housing 41 of the housing 40 so that the support part 52 and the standard lens group 300 are held in the housing space 43 of the housing 40, wherein the standard lens group 300 corresponds to the assembly channel 413 of the main housing 41.

[0104] Reference Appendix Figure 1C The image-side lens group 30 is installed in the housing space 43 of the housing 40.

[0105] Reference Appendix Figure 1D The object-side lens group 10 is attached to the flange 412 of the main housing 41. At this time, the object-side lens group 10, the standard lens group 300 and the image-side lens group 30 are approximately coaxial.

[0106] Next, the object-side lens group 10, the standard lens group 300, and the image-side lens group 30 are calibrated according to their sensitivity in the overall optical lens 100.

[0107] It is worth mentioning that the relationship between the object-side lens group 10, the standard lens group 300, and the image-side lens group 30 is as follows: (1) the gap in the Z direction mainly affects the field curvature of the optical lens 100; (2) the position in the XY direction mainly affects the peak value of the optical lens 100; (3) the tilt between the upper lens group 10, the standard lens group 300, and the lower lens group 30 mainly affects the tilt and astigmatism of the optical lens 100. Therefore, when designing the optical lens 100, it is necessary to consider the sensitivity of the overall optical performance of the optical lens 100 in a balanced way, that is, to avoid making a specific lens or a specific lens group too sensitive to the relationship between the object-side lens group 10, the standard lens group 300, and the image-side lens group 30, so as to cause the overall optical performance of the optical lens 100 to decrease due to the excessive sensitivity of the lens or the lens group. However, due to the different functions of the lenses and the different optical powers, there will inevitably be lens groups with sensitivity ranging from low to high. Generally, the sensitivity of the lens group increases sequentially from the image side to the object side. That is, the sensitivity of the standard lens group 300 is higher than that of the image-side lens group 30, and the sensitivity of the object-side lens group 10 is higher than that of the standard lens group 300.

[0108] Therefore, the specific steps for calibrating the object-side lens group 10, the standard lens group 300, and the image-side lens group 30 are as follows: First, calibrate the standard lens group 300 with the image-side lens group 30 as a reference; second, calibrate the object-side lens group 10 with the image-side lens group 30 and the standard lens group 300 as references.

[0109] Specifically, in the appendix Figure 1C In the stage shown, the image-side lens group 30 can be fixedly mounted to the mounting arm 414 of the main housing 41, so that the image-side lens group 30 is positioned in the housing space 43 of the outer housing 40, that is, the positional relationship between the image-side lens group 30 and the outer housing 40 is no longer adjusted. Because in the attached... Figure 1A In the stage shown, the standard lens group 300 is pre-fixed to the support ring 522 of the support portion 52. Therefore, the standard lens group 300 can be calibrated by adjusting the positional relationship (including the Z and XY directions) between the standard lens group 300 and the support ring 522, using the image-side lens group 30 as a reference. (See attached...) Figure 1D In the stage shown, the object-side lens group 10 is pre-attached to the flange 412 of the main housing 41. After calibrating the object-side lens group 10 with reference to the image-side lens group 30 and the standard lens group 300, the mounting relationship between the object-side lens group 10 and the main housing 41 is then fixed. For example, in the attached... Figure 1DIn the stage shown, the object-side lens group 10 can be pre-attached to the flange 412 of the main housing 41 by adhesive. After calibrating the object-side lens group 10 with the image-side lens group 30 and the standard lens group 300 as references, the mounting relationship between the object-side lens group 10 and the main housing 41 is fixed by curing adhesive.

[0110] Reference Appendix Figure 1E and Figure 1F The standard lens group 300 is removed via the assembly channel 413 of the main housing 41. During the removal of the standard lens group 300, to prevent the main housing 41 from scraping against it, the standard lens group 300 is removed laterally. That is, the standard lens group 300 is moved along a direction perpendicular to the optical axis of the optical lens 100 via the assembly channel 413 of the main housing 41 to perform the removal operation.

[0111] Reference Appendix Figure 1G and Figure 1H The focusing lens group 20 is moved into the main housing 41 through the assembly channel 413, and pre-fixed to the support ring 522 of the support part 52. During the movement of the focusing lens group 20, to prevent the main housing 41 from scraping against it, the focusing lens group 20 is moved laterally. That is, the focusing lens group 20 is moved along the optical axis perpendicular to the optical lens 100 via the assembly channel 413 of the main housing 41 to perform the movement operation.

[0112] Preferably, the focusing lens group 20 consists of a focusing lens 21, wherein the thickness of the focusing lens 21 is smaller than the height of the assembly channel 413 of the main housing 41, and the width of the focusing lens 21 is smaller than the width of the assembly channel 413 of the main housing 41, so as to allow the focusing lens 21 to be smoothly moved into the housing space 43 of the outer shell 40 and the support ring 522 pre-fixed to the support part 52 via the assembly channel 413 of the main housing 41.

[0113] Preferably, the focusing lens 21 has at least one clamping portion 211 to facilitate clamping by a clamp when assembling the focusing lens 21.

[0114] In a specific example of the optical lens 100 of the present invention, the focusing lens group 20 is pre-fixed to the carrier ring 522 of the carrier portion 52 by adhesive.

[0115] After the focusing lens group 20 is pre-fixed to the support ring 522 of the support portion 52, the focusing lens group 20 is calibrated with reference to the object-side lens group 10 and the image-side lens group 30. For example, the focusing lens group 20 is calibrated by adjusting the positional relationship (including the X and XY directions) between the focusing lens group 20 and the support ring 522. At this time, the adhesive used to pre-fix the focusing lens group 20 and the support ring 522 can fill the gap between the focusing lens group 20 and the support ring 522 and adjust the relative position of the focusing lens group 20 and the support ring 522. After the focusing lens group 20 is calibrated, the focusing lens group 20 and the support ring 522 can be fixed by curing the adhesive.

[0116] Reference Appendix Figure 1I The cover 60 is attached, wherein the bottom side of the cover 60 extends to and is attached to the main housing 41, and the inner side of the cover 60 extends to and is attached to the object-side lens barrel 11 of the object-side lens group 10, so as to allow the cover 60 to close the assembly channel 413 of the main housing 41, thereby preventing dust and other contaminants from entering the housing space 43 of the housing 40 through the assembly channel 413 of the main housing 41 and contaminating the focusing lens group 20 and the image-side lens group 30.

[0117] During the assembly process of the optical lens 100 of the present invention, the optical lens 100 can be calibrated under high threshold performance by introducing the standard lens group 300, so as to accurately calibrate the eccentricity and compensate for the assembly errors of the object-side lens group 10, the focusing lens group 20 and the image-side lens group 30.

[0118] Appendix Figure 3 and Figure 4 A camera module 1000 according to a preferred embodiment of the present invention is shown, wherein the camera module 1000 includes a photosensitive component 200 and an optical lens 100 disposed on the photosensitive component 200.

[0119] The photosensitive assembly 200 includes a circuit board 201, a photosensitive chip 202, a lens mount 203, and a filter 204. The photosensitive chip 202 is mounted on the circuit board 201. The lens mount 203 is disposed on the circuit board 201 such that it at least surrounds the photosensitive area of ​​the photosensitive chip 202. The filter 204 is mounted on the top side of the lens mount 203 such that it is held in the photosensitive path of the photosensitive chip 202. The optical lens 100 is directly disposed on the lens mount 203. Incident light, after passing sequentially through the optical lens 100 and the filter 204 of the photosensitive assembly 200, can be received by the photosensitive chip 202, so that the photosensitive chip 202 can subsequently perform photoelectric conversion to form an image.

[0120] Preferably, the lens mount 203 is integrally formed on the circuit board 201. This eliminates the need for an adhesive layer between the lens mount 203 and the circuit board 201, thus reducing the height of the camera module 1000. Furthermore, the lens mount 203 strengthens the circuit board 201, ensuring its flatness. Preferably, the lens mount 203 may further embed a portion of the non-photosensitive area of ​​the photosensitive chip 202, thereby integrally combining the lens mount 203 with both the circuit board 201 and the photosensitive chip 202.

[0121] In addition, the photosensitive component 200 further includes at least one electronic component 205, wherein the electronic component 205 is mounted on the circuit board 201, and the lens mount 203 may embed the electronic component 105.

[0122] Appendix Figure 5 An electronic device according to a preferred embodiment of the present invention is shown, wherein the electronic device includes an electronic device body 2000 and a camera module 1000 disposed on the electronic device body 2000. Preferably, the camera module 1000 is disposed on the front side of the electronic device body 2000 to form a front-facing camera module.

[0123] The optical lens 100 of the camera module 1000 has a built-in focusing function. That is, the camera module 1000 achieves focusing by driving the focusing lens group 20. In this way, during the focusing process of the camera module 1000, the positions of the object-side lens group 10 and the image-side lens group 30 relative to the photosensitive component 200 remain unchanged, so as not to affect the total optical length of the optical lens 100. Therefore, the electronic device body 2000 does not need to reserve space for the optical lens 100 of the camera module 1000 to move, which is conducive to the thinning and lightening of the electronic device.

[0124] Furthermore, the object-side lens group 10 of the optical lens 100 of the camera module 1000 is relatively small in size, and the object-side lens group 10 protrudes from the housing 40, thus enabling the camera module 1000 to adopt a "small head" design. In this way, when the camera module 1000 is used as the front-facing camera module of the electronic device, on the one hand, the object-side lens group 10 can be closer to the opening position of the screen of the electronic device, which is conducive to the camera module 1000 obtaining a larger field of view and light transmission, thereby improving the imaging quality of the camera module 1000. On the other hand, it does not increase the size of the screen opening, thus meeting the requirement of miniaturization of the opening.

[0125] Appendix Figures 6 to 7B The camera module 1000 according to another preferred embodiment of the present invention is shown, along with an attached... Figure 3 and Figure 4 The difference between the camera module 1000 shown is that, in the attached... Figures 6 to 7B In this specific example of the camera module 1000 shown, the focusing lens group 20 includes a focusing lens barrel 22 and at least one focusing lens 21 disposed on the focusing lens barrel 22.

[0126] Furthermore, an annular groove 111 is provided on the bottom side of the object-side lens barrel 11 of the object-side lens group 10. In this way, when the cover 60 is attached, the glue used to bond the inner side of the cover 60 and the object-side lens group 10 can enter the annular groove 111 of the object-side lens barrel 11 after overflowing. In this way, on the one hand, it can prevent the overflowing glue from contaminating the object-side lens group 10, the focusing lens group 20 and the image-side lens group 30 in the housing space 43 of the housing 40. On the other hand, it can prevent the overflowing glue from forming a protrusion on the inner wall of the housing 40 or the inner wall of the cover 60 and causing stray light.

[0127] Preferably, a protrusion 221 of the focusing lens barrel 22 of the focusing lens group 20 corresponds to the annular groove 111 of the object-side lens barrel 11, and when the focusing lens group 20 is driven, the protrusion 221 of the focusing lens barrel 22 can enter the annular groove 111 of the object-side lens barrel 11, so as to allow the object-side lens group 10 to avoid the image-side lens group 20. In this way, the focusing lens group 20 can have a larger travel range.

[0128] It is worth mentioning that the bottom side of the object-side lens barrel 11 forms the annular groove 111 by setting two convex rings 112. The two convex rings 112 of the object-side lens barrel 11 and the protrusion 221 of the focusing lens barrel 22 cooperate with each other to reduce stray light, thereby improving the imaging effect of the camera module 1000.

[0129] According to one aspect of the present invention, the present invention provides a method for assembling the optical lens 100, wherein the assembly method includes the following steps:

[0130] (a) The object-side lens group 10 is disposed in the housing space 43 of the housing 40;

[0131] (b) Mounting the object-side lens group 10 onto the housing 40 such that it protrudes from the housing 40; and

[0132] (c) Using the image-side lens group 30 and the object-side lens group 10 as a reference, after calibrating the focusing lens group 20, fix the focusing lens group 20 to the support portion 52 which is drivably disposed in the housing space 43 of the housing 40 to obtain the optical lens 100.

[0133] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and any variations or modifications may be made to the implementation of the present invention without departing from the stated principles.
