Technical Field

Background
In recent years, the market has increasingly demanded higher imaging quality of the camera module of the portable electronic device (for example, a smart phone), and one of the concrete features is that people often expect the front camera module of the portable electronic device to have focusing capability so as to obtain better imaging effect. However, based on the prior art, the premise of the camera module having the focusing capability is to arrange a driver (e.g., a voice coil motor), that is, an optical lens of the camera module is mounted on the driver, and the driver drives the optical lens to move along the optical axis direction of the camera module to achieve focusing of the camera module, whereas the camera module is inevitably larger in size due to the arrangement of the driver on the camera module, which not only increases the radial dimension (the dimension perpendicular to the optical axis direction of the camera module) but also increases the axial dimension (the optical axis direction of the camera module, that is, the thickness direction of the portable electronic device), obviously, the development direction of the front camera module of the portable electronic device equipped with the driver is contrary to the development direction of the light and thin portable electronic device. Therefore, the front camera module of the portable electronic device is often a fixed-focus camera module, and the fixed-focus camera module is difficult to adjust the focal length in the shooting process, so that the shooting effect of the fixed-focus camera module has a large defect. The present inventors have made an effort to provide a front camera module disposed in a portable electronic device with focusing capability.

It should be noted that the number of the elastic pieces 202 of the optical lens 200 of the present invention is not limited, for example, in the preferred example of the optical lens 200 of the present invention, the optical lens 200 includes one elastic piece 202, the outer side of the elastic piece 202 extends to and is fixedly connected to the upper side of the fixing portion 51, and the inner side of the elastic piece 202 extends to and is fixedly connected to the upper side of the driven member 521; alternatively, the outer side of the elastic sheet 202 extends to and is fixedly connected to the lower side of the fixing portion 51, and the inner side of the elastic sheet 202 extends to and is fixedly connected to the lower side of the driven element 521. Alternatively, in other examples of the optical lens 200 of the present invention, the optical lens 200 includes two of the elastic pieces 202, an outer side of one of the elastic pieces 202 extends to and is fixedly connected to an upper side of the fixing portion 51 and an inner side extends to and is fixedly connected to an upper side of the driven member 521, an outer side of the other of the elastic pieces 202 extends to and is fixedly connected to a lower side of the fixing portion 51 and an inner side extends to and is fixedly connected to a lower side of the driven member 521.

It should be noted that the coil 532 of the driving portion 53 can be electrically connected to the circuit board 101 of the photosensitive assembly 100 to allow power to be supplied to the coil 532 of the driving portion 53 through the circuit board 101, so that the camera module can be assembled to an electronic device.

With continued reference to fig. 1 to 6F, the fixing portion 51 is annular and located outside the focus lens group 20, wherein the driving portion 53 includes two magnets 531, the two magnets 531 are symmetrically disposed on two opposite sides of the fixing portion 51, and thus the two magnets 531 are symmetrically disposed outside the focus lens group 20. The outer carrying side 5201 of the carrying part 52 is annular and is located outside the focus lens group 20, wherein the driving part 53 includes a coil 532, and the coil 532 is wound around the outer carrying side 5201 of the carrying part 52, so that the coil 532 is annular and is located outside the focus lens group 20. With the above-mentioned structure, when the coil 532 is powered, the magnetic field generated by the annular coil 532 interacts with the two symmetrically arranged magnets 531, so that the focusing lens group 20 can be driven by the carrying part 52 in a balanced manner along the optical axis direction of the camera module, thereby preventing the focusing lens group 20 from tilting when being driven, and ensuring the optical performance of the camera module.
Preferably, the bearing portion 52 forms an annular winding slot 5203 on the bearing outer side 5201, wherein the coil 532 is wound around the winding slot 5203 of the bearing portion 52, so as to ensure that the coil 532 is fixedly disposed on the bearing outer side 5201 of the bearing portion 52.
It should be noted that the assembly manner of the magnet 531 and the fixing portion 51 of the driving portion 53 is not limited in the optical lens 200 of the present invention, and for example, the magnet 531 may be adhered to the inner wall of the fixing portion 51 so that the magnet 531 is fixedly disposed on the fixing portion 51. In the preferred example of the optical lens 200 shown in fig. 1 to 6F, the fixing portion 51 has at least one fitting groove 511, wherein the magnet 531 is fitted into the fitting groove 511 of the fixing portion 51, so that the magnet 531 is fixedly disposed in the fitting groove 511 of the fixing portion 51.

Specifically, referring to fig. 1 to fig. 6F, the carrying portion 52 further includes a driven element 521, a carrying ring 522 and at least one extending arm 523 extending between the driven element 521 and the carrying ring 522, wherein the driven element 521 is formed on the carrying outer side 5201 of the carrying portion 52 to allow the coil 532 of the driving portion 53 to wind around the driven element 521, and the carrying ring 522 forms the carrying inner side 5202 of the carrying portion 52 to allow the focusing lens group 20 to be fixedly disposed on the carrying ring 522. The extension arm 523 of the bearing part 52 is movably disposed on the moving channel 47 of the housing 40, so that the driven element 521 and the bearing ring 522 of the bearing part 52 can be respectively held at two opposite sides of the mounting arm 46 of the housing 40.
Preferably, the bearing part 52 includes two extension arms 523, and the two extension arms 523 extend between the driven element 521 and the bearing ring 522 symmetrically.

Preferably, at least a part of the extension arm 523 of the bearing portion 52 is inclined, so that the height position of the bearing outer side 5201 of the bearing portion 52 can be lower than the height position of the bearing inner side 5202 to sink the coil 532 of the driving portion 53. In other words, the height position of the driven element 521 of the bearing part 52 is lower than the height position of the bearing ring 522, so that the bearing part 52 is disposed to make the driven element 521 surround the lower lens group 30 and to keep the bearing ring 522 on the upper side of the lower lens group 30.
Specifically, referring to fig. 2 to 3B and 5A to 6F, the extension arm 523 of the bearing portion 52 has a lower horizontal extension portion 5231, an upper horizontal extension portion 5232 and an inclined extension portion 5233, wherein the lower horizontal extension portion 5231 integrally extends inward from the driven member 521, the upper horizontal extension portion 5232 integrally extends outward from the bearing ring 522, and opposite ends of the inclined extension portion 5233 respectively extend to and are connected to the lower horizontal extension portion 5231 and the upper horizontal extension portion 5232, so that the height position of the driven member 521 of the bearing portion 52 is lower than the height position of the bearing ring 522 to sink the coil 532 of the driving portion 53, thereby facilitating to reduce the height dimension of the camera module.
In an alternative example of the optical lens 200 of the present invention, the extension arm 523 of the carrying part 52 is composed of the lower horizontally extending portion 5231 and the inclined extending portion 5233, wherein the lower horizontally extending portion 5231 integrally extends inward from the driven member 521, and opposite ends of the inclined extending portion 5233 extend to and are connected to the lower horizontally extending portion 5231 and the carrying ring 522, respectively.
In another alternative example of the optical lens 200 of the present invention, the extension arm 523 of the carrying part 52 is composed of the upper horizontally extending portion 5232 and the inclined extending portion 5233, wherein the upper inclined extending portion 5232 integrally extends outward from the carrying ring 522, and opposite ends of the inclined extending portion 5233 extend to and are connected to the upper horizontally extending portion 5232 and the driven piece 521, respectively.
In another alternative example of the optical lens 200 of the present invention, the extension arm 523 of the carrying part 52 is inclined as a whole, that is, opposite ends of the extension arm 523 extend to and are connected to the driven element 521 and the carrying ring 522 in a manner that the extension arm 523 is inclined as a whole, respectively.
Further, the driving mechanism 50 further includes a carrier 54, wherein the carrier 54 surrounds the second lens 21 of the focusing lens group 20, and the carrier 54 is mounted on the carrier ring 522 of the carrying portion 52, so that the focusing lens group 20 is fixedly mounted on the carrying portion 52 by the carrier 54. The second lens 21 of the focus lens group 20 can be adhered to the carrier 54 by glue, that is, the carrier 54 is a component for carrying the focus lens group 20, wherein the clamping portion 211 of the second lens 21 increases the adhering area of the focus lens group 20 and the carrier 54, so as to ensure the reliability of the camera module.
With continued reference to fig. 1 to 6F, the housing 40 has at least one avoiding space 48, the avoiding space 48 communicates with the housing space 41 and the top opening 42, wherein the extension arm 523 of the carrying portion 52 corresponds to the avoiding space 48 of the housing 40 to allow the housing 40 to avoid the extension arm 523 of the carrying portion 52, so that the focusing lens group 20 is allowed to have a larger stroke range. It can be understood that the width dimension of the avoiding space 48 of the housing 40 is slightly larger than the width dimension of the extending arm 523 of the carrying portion 52, so that when the focus lens group 20 is driven to move along the optical axis direction of the camera module, the extending arm 523 of the carrying portion 52 can be prevented from touching the housing 40, thereby ensuring the reliability of the camera module. Preferably, the size of the escape space 48 of the housing 40 is slightly larger than the size of the focus lens group 20, so that the focus lens group 20 is allowed to move into the housing space 41 of the housing 40 through the escape space 48 of the housing 40.
Preferably, the housing 40 has two avoidance spaces 48, the two avoidance spaces 48 are symmetrically formed at two opposite sides of the top opening 42, wherein each extension arm 523 of the bearing part 52 corresponds to each avoidance space 48 of the housing 40.
Further, the optical lens 200 includes a cover 60, wherein the cover 60 has a central through hole 61, wherein the cover 60 is attached to the case body 44 of the housing 40 in such a manner that the upper lens group 10 is held at the central through hole 61 of the cover 60, and the cover 60 closes the escape space 48 of the housing 40, in such a manner that contaminants such as dust can be prevented from entering the inside of the optical lens 200 through the escape space 48 of the housing 40 of the optical lens 200, thus ensuring the reliability of the optical lens 200.
Further, the optical lens 200 includes a base 70, the base 70 has a light channel 71, wherein the base 70 is attached to the surrounding body 45 of the housing 40 in a manner that the lower lens group 30 corresponds to the light channel 71 of the base 70, so that the upper lens group 10, the housing 40 and the lens holder 70 form a general appearance of the optical lens 200. The base 70 of the optical lens 200 is attached to the lens holder 103 of the photosensitive component 100, so that the optical lens 200 is disposed in the photosensitive path of the photosensitive component 100 to form the camera module.
Fig. 7 shows a modified example of the camera module of the present invention, and unlike the camera module shown in fig. 1 to 6F, in this specific example of the camera module shown in fig. 7, the lower lens group 30 is directly fixedly provided to the base 70, so that the relative positional relationship between the lower lens group 30 and the upper lens group 10 is ensured by the cooperation of the base 70 and the housing 40. For example, the periphery of the third barrel 31 of the lower lens group 30 may be adhered to the base 70 by glue, so as to allow the lower lens group 30 to be directly and fixedly disposed on the base 70.
Fig. 6F shows an assembly process of the optical lens 200 of the present invention, which includes the following stages:
pre-fixing a standard lens group 300 on the carrying ring 522 of the carrying part 52;
the bearing part 52 is movably disposed in the housing space 41 of the housing 40 in a manner that the standard lens group 300 corresponds to the avoiding space 48 of the housing 40, and at this time, the bottom surface of the standard lens group 300 is higher than the surface of the housing body 44 of the housing 40, so as to allow the standard lens group 300 to be transversely removed in the subsequent process;
fixedly arranging the lower lens group 30 in the housing space 41 of the housing 40 and pre-fixing the upper lens group 10 in the housing 40, wherein the lower lens group 30, the standard lens group 300 and the upper lens group 10 are substantially coaxial;
calibrating the lower lens group 30, the standard lens group 300, and the upper lens group 10;
the standard lens group 300 is removed and the focusing lens group 20 is moved into the avoiding space 48 of the housing 40 to obtain the optical lens.
In the process of assembling the optical lens 200, the overall threshold of the optical lens 200 can be increased by introducing the standard lens group 300, so that the optical lens 200 can be adjusted under the high threshold performance.
Preferably, in the assembling process of the optical lens 200, after the focusing lens group 20 replaces the standard lens group 300, the upper lens group 10, the focusing lens group 20 and the lower lens group 30 are calibrated again, so as to be beneficial to ensuring the optical performance of the optical lens 200 and the imaging quality of the camera module.
Preferably, during the assembly of the optical lens 200, the standard lens group 300 is removed by removing the standard lens group 300 through the avoiding space 48 of the housing 40 along a direction perpendicular to the optical axis of the optical lens 200, and correspondingly, the focus lens group 20 is moved into the focus lens group 20 through the avoiding space 48 of the housing 40 along a direction perpendicular to the optical axis of the optical lens 200.
According to another aspect of the present invention, the present invention further provides an assembling method of the optical lens 200, wherein the assembling method comprises the following steps:
(a) Fixedly disposing the lower lens group 30 in the housing space 41 of the housing 40;
(b) Mounting the upper lens group 10 on the housing 40 in such a manner that the upper lens group 10 protrudes from the housing 40; and
(c) The focusing lens group 20 is drivably disposed in the housing space 41 of the housing 40 in such a manner that the upper lens group 10, the focusing lens group 20, and the lower lens group 30 have the same optical axis, so as to obtain the optical lens.
Preferably, before the step (b), the assembling method further comprises the steps of:
(d) Pre-fixing the upper lens group 10 on the housing 40;
(e) Holding the standard lens group 300 between the upper lens group 10 and the lower lens group 30 such that the upper lens group 10, the standard lens group 300, and the lower lens group 30 have the same optical axis;
(f) Calibrating the standard lens group 300 with the lower lens group 30 as a reference; and
(g) The upper lens group 10 is calibrated with reference to the lower lens group 30 and the standard lens group 300.
In the assembling method of the present invention, the overall threshold of the optical lens 200 can be increased by introducing the standard lens group 300, so that the optical lens 200 can be adjusted under the high threshold performance.
It should be noted that the relationship among the upper lens group 10, the focus lens group 20, and the lower lens group 30 of the optical lens 200 is: (1) The Z-direction gap mainly affects the curvature of field of the optical lens 200; (2) The position in the XY direction mainly affects the peak value of the optical lens 200; (3) The tilt among the upper lens group 10, the focus lens group 20, and the lower lens group 30 mainly affects the tilt, astigmatism, and the like of the optical lens 200. Since the focus lens group 20 is replaced with the standard lens group 300 in the assembly method, the relationship of the upper lens group 10, the standard lens group 300, and the lower lens group 30 also satisfies the above.
Therefore, when the optical lens 200 is optically designed, it is necessary to balance the sensitivity of the overall optical performance of the optical lens 200, that is, a specific lens or a specific lens group is not so sensitive due to the relationship among the upper lens group 10, the focus lens group 20, and the lower lens group 30 that the overall optical performance of the optical lens 200 is degraded due to the higher sensitivity of the lens or the lens group 1. However, due to different functions and different focal powers of the lenses, there tend to exist lens groups with sensitivity gradually increasing from low to high, and in general, the sensitivity of the lens groups sequentially increases in order from the image side to the object side, that is, the sensitivity of the focus lens group 20 is higher than that of the lower lens group 30, and the sensitivity of the upper lens group 10 is higher than that of the focus lens group 20 (or the sensitivity of the standard lens group 300 is higher than that of the lower lens group 30, and the sensitivity of the upper lens group 10 is higher than that of the standard lens group 300). Therefore, in the assembly method of the present invention, after the Z-direction gaps of the upper lens group 10, the standard lens group 300, and the lower lens group 30 are calibrated, the XY-direction positions of the upper lens group 10, the focus lens group 20, and the lower lens group 30 need to be sequentially calibrated in such a manner that the sensitivities of the upper lens group 10, the standard lens group 300, and the lower lens group 30 in the entire optical lens 200 are increased from low to high, thereby ensuring the overall optical performance of the optical lens 200.
Further, in the above method, after removing the standard lens group 300, firstly, the focusing lens group 20 is allowed to move into the housing space 41 of the housing 40 along the direction perpendicular to the optical axis of the optical lens 200 through the avoiding space 48 of the housing 40, and secondly, the focusing lens group 20 is aligned with the lower lens group 30 and the upper lens group 10 as a reference to set the focusing lens group 20 in the housing space 41 of the housing 40.
Preferably, in the step (e), the standard lens group 300 is carried between the upper lens group 10 and the lower lens group 30 by the carrying portion 52, and after the standard lens group 300 is removed, the focusing lens group 20 is moved to the carrying portion 52 and the carrying portion 52 carries the focusing lens group 20 in the housing space 41 of the housing 40. More preferably, the gap between the upper lens group 10 and the housing 40 is smaller than the gap between the focusing lens group 20 and the carrying portion 52, so that when the focusing lens group 20 is calibrated with the lower lens group 30 and the upper lens group 10 as a reference, the focusing lens group 20 can be provided with a larger compensation range, so as to compensate for errors and ensure the imaging quality of the camera module to which the optical lens 200 is applied.
According to another aspect of the present invention, the present invention further provides an assembling method of an optical lens, wherein the assembling method includes the steps of:
(A) The carrying ring 522 for pre-fixing the standard lens group 300 on the carrying part 52;
(B) The carrying part 52 is movably disposed in the housing space 41 of the housing 40 in such a manner that the standard lens group 300 corresponds to the avoiding space 48 of the housing 40;
(C) Fixedly arranging the lower lens group 30 in the housing space 41 of the housing 40 and pre-fixing the upper lens group 10 in the housing 40, wherein the lower lens group 30, the standard lens group 300 and the upper lens group 10 are substantially coaxial;
(D) Calibrating the lower lens group 30, the standard lens group 300, and the upper lens group 10; and
(E) The standard lens group 300 is removed and the focus lens group 20 is moved in through the escape space 48 of the housing 40 to obtain the optical lenses.
Preferably, the assembly method further comprises the steps of: (F) The cover 60 is allowed to close the avoidance space 48 of the housing 40 to prevent contaminants such as dust from entering the inside of the optical lens 200 through the avoidance space 48 of the housing 40 of the optical lens 200, thus ensuring the reliability of the optical lens 200.
