Technical Field

[0001] The invention relates to a camera module and an electronic device, in particular to a camera module suitable for the electronic device. Background Art

[0002] As semiconductor process technology becomes more sophisticated, the performance of electronic photosensitive elements has been improved, and pixels can reach a smaller size. Therefore, optical lenses with high imaging quality have become an indispensable part. In addition, with the rapid development of technology, the application range of mobile devices equipped with optical lenses has become wider, and the requirements for optical lenses have also become more diverse.

[0003] Generally speaking, the lens can be moved by the drive of the lens driving device to perform autofocus. However, when the lens is tilted, the focus position will be offset between the best imaging position of the optical lens group and the imaging surface where the photosensitive element is located, resulting in poor imaging quality of the peripheral image. In addition, the lens assembly currently on the market often uses a voice coil motor (VCM) as a lens driving device for lens autofocus. However, such a lens driving device is usually composed of multiple parts, and in order to meet the requirements for precision and smoothness when the lens moves, multiple alignment and correction steps are required during the assembly process to accurately assemble the multiple parts one by one, thereby limiting the production efficiency and manufacturing qualification rate of the lens assembly.

[0004] Therefore, how to improve the lens assembly to simplify its structure, improve assembly accuracy, and maintain good imaging quality to meet the current high-standard requirements for electronic devices has become an important issue in the relevant field. Summary of the invention

The optical imaging lens is arranged in the shell. The base is connected to the shell, the base has a through hole, and the optical axis passes through the center of the through hole. The image sensing module is arranged on the image side of the axial driver, and the image sensing module comprises an image sensor and a substrate. The image sensor is used to convert the light passing through the imaging lens module into an image signal. The substrate faces the axial driver, and the substrate and the base of the axial driver bear against each other. Among them, the base has a first axial connection structure, the substrate has a second axial connection structure, and the first axial connection structure is connected to the second axial connection structure, so that the relative position between the imaging lens module and the image sensing module is aligned along the direction of the optical axis.

[0093] The detailed features and advantages of the present invention are described in detail in the following embodiments, and the contents are sufficient to enable any person skilled in the art to understand the technical content of the present invention and implement it accordingly, and according to the contents disclosed in this specification, the scope of the patent application and the drawings, any person skilled in the art can easily understand the relevant purposes and advantages of the present invention. The following examples further illustrate the viewpoints of the present invention in detail, but do not limit the scope of the present invention in any viewpoint.

[0094] The invention provides a camera module, which comprises an imaging lens module, an axial driver and an image sensing module. The imaging lens module comprises at least one optical imaging lens and has an optical axis.

[0095] The axial drive is used to drive the optical imaging lens to move in a direction parallel to the optical axis, and the axial drive includes a housing and a base. The optical imaging lens is disposed in the housing. The base is connected to the housing, and the base has a through hole, and the optical axis passes through the center of the through hole. The axial drive may be, for example, a micro-electro-mechanical-system actuator (MEMS Actuator), a piezoelectric motor, or a voice coil motor, but the present invention is not limited thereto.

[0096] The image sensing module is arranged on the image side of the axial driver, and the image sensing module includes an image sensor and a substrate, wherein the image sensor is used to convert the light passing through the imaging lens module into an image signal, the substrate faces the axial driver, and the substrate and the base of the axial driver support each other.

[0097] The base of the axial driver has a first axial connection structure, and the substrate of the image sensing module has a second axial connection structure, wherein the first axial connection structure is supported and connected to the second axial connection structure, so that the relative position between the imaging lens module and the image sensing module is aligned along the direction of the optical axis. In this way, the assembly process of the camera module is simplified by the axial connection structure, and the position of the imaging lens module and the image sensor is maintained, which can avoid image offset and skew. In addition, the assembly with the axial connection structure helps the miniaturization of the camera module. The material of the aforementioned base and substrate can be, for example, polycarbonate (PC), liquid crystal polymer (LCP), polypropylene (PP), resin (Resin) or synthetic resin (Synthetic Resin), but the present invention is not limited thereto. Among them, the base and the substrate can be manufactured by injection molding (Injection Molding), laser direct structuring (LDS), compression molding (Compression Molding) or insert molding (Insert Molding), but the present invention is not limited thereto. The shapes of the first axial connection structure and the second axial connection structure may be annular, rectangular or arc-shaped, but the present invention is not limited thereto.

[0098] The camera module disclosed in the present invention may further include a filter disposed between the imaging lens module and the image sensor to filter out light of a specific wavelength band in the incident light. The substrate may serve as a support for the filter to support the filter.

[0099] The first axial connection structure may include a plane connected to each other and forming an angle and at least one inclined surface, and the second axial connection structure may include a plane connected to each other and forming an angle and at least one inclined surface, wherein the planes are substantially perpendicular to the optical axis, the plane of the first axial connection structure bears against the plane connected to the second axial connection structure, and the inclined surface of the first axial connection structure bears against the inclined surface connected to the second axial connection structure. The plane is used to maintain the distance between the imaging lens module and the image sensor and prevent skew, and the inclined surface is used to align the optical axis of the imaging lens module to the geometric center of the image sensor. Thereby, the assembly coaxiality of the components can be improved through high-precision assembly configuration. The plane being substantially perpendicular to the optical axis means that the angle between the optical axis and the plane is 90 degrees or close to 90 degrees.

[0100] The first axial connection structure and the second axial connection structure may both have smooth surfaces, thereby reducing the difficulty of molding and improving the fit between the first axial connection structure and the second axial connection structure.

[0101] The first axial connection structure is located at a bottom of the base facing the image sensing module, and the first axial connection structure can be raised from the bottom toward the image sensing module; the second axial connection structure is located at a top of the base facing the axial driver, and the second axial connection structure can be recessed from the top toward the direction away from the axial driver. This helps to improve the manufacturability of mold forming and increase the product qualification rate.

[0102] At least one inclined surface of the second axial connection structure surrounds at least one inclined surface of the first axial connection structure, thereby enabling the camera module to maintain a relatively small volume.

[0103] The first axial connection structure and the second axial connection structure can both have the optical axis passing through their centers and can both surround the through hole of the base. Thus, through the dimensional accuracy design of the easy-to-control tube, the camera module is suitable for mass production and maintains the optical imaging quality. The first axial connection structure and the second axial connection structure can both be axially symmetrical with the optical axis as the center axis.

[0104] In the camera module disclosed by the present invention, the axial driver may further include a driving coil and a driving magnet, wherein the driving coil may be arranged on the outside of the imaging lens module, and the driving magnet may face the driving coil in a direction perpendicular to the optical axis; thereby, the imaging lens module may be provided with an automatic focusing function. The driving magnet and the driving coil may be arranged symmetrically with respect to the optical axis; thereby, it helps to balance the force of the axial driver to prevent the mechanism from being skewed. In one embodiment, the axial driver may further include a magnet carrier arranged in the housing, and the driving magnet may be fixed on the magnet carrier. In one embodiment, the housing of the axial driver may be used as a magnet carrier for the driving magnet to be fixed thereon.

[0105] In the camera module disclosed in the present invention, the image sensing module may further include an image stabilization driver, wherein the image stabilization driver is used to drive the image sensor to move along at least one direction perpendicular to the optical axis; thereby, the image sensing module can have the function of optical image stabilization. The image sensing module is provided with an image stabilization driver to reduce the volume of the imaging lens module so as to use the overall space more efficiently. The image stabilization driver can also drive the image sensor to rotate around the optical axis. The image stabilization driver can be, for example, a micro-electromechanical system actuator, a piezoelectric motor or a voice coil motor, but the present invention is not limited thereto.

[0106] In the camera module disclosed in the present invention, the image sensing module may further include an elastic wire, a flexible circuit board, an elastic element or a suspension element to connect the image sensor and the substrate, so that the image sensor is movably disposed on the substrate and can be used to transmit the electrical signal of the image sensor and provide the image sensor with the freedom of translation or rotation along a direction perpendicular to the optical axis, but the present invention is not limited thereto.

[0107] The through hole of the base of the axial driver can be a tip opening, and the base can also have an inner bevel surrounding the tip opening, and the area surrounded by the inner bevel gradually shrinks toward the image sensing module in a direction parallel to the optical axis; thereby, it helps to improve the efficiency of shielding non-imaging light. Among them, the minimum inner diameter of the through hole can be smaller than the maximum outer diameter of the imaging lens module; thereby, it helps to reduce the probability of stray light generated at the image side of the imaging lens module.

[0108] The base may further have at least three injection marks, and the injection marks may be located at the chamfered corners of the base, for example; thereby, it can be ensured that the injection mark cutouts do not interfere with other mechanisms.

[0109] In the camera module disclosed in the present invention, the imaging lens module may further include a single component, wherein the optical imaging lens is disposed in the single component, and the single component is disposed between the housing and the base of the axial drive. Thus, compared with the lens assembly in the prior art, which includes two components, a lens barrel and a lens holder, which are assembled with a threaded portion, the single component can reduce dust during the assembly of the conventional lens barrel and the lens holder by a screw-free design and reduce the overall volume. The single component is, for example, a plastic injection molding component that can be installed on the axial drive and can be used to load the optical imaging lens. The driving coil of the axial drive can be disposed outside the single component.

[0110] The camera module disclosed in the present invention may further include a position sensing magnet and a position sensor, wherein the position sensing magnet may be disposed on a single component, and the position sensor may be disposed on at least one of the substrate of the image sensing module and the base of the axial driver, and the position sensor corresponds to the position sensing magnet to detect the position of the imaging lens module. Thus, a closed-loop design with sufficient space can be configured to speed up the focusing speed.

[0111] In the camera module disclosed in the present invention, the base may include a terminal portion extending along the optical axis toward the substrate of the image sensor module, and the terminal portion is used to provide a driving signal to the axial driver, wherein the terminal portion may be welded to the substrate. Thus, the design of the axial connection structure can prevent the terminal portion from generating mechanical interference during assembly, thereby improving welding efficiency.

[0112] The various technical features of the camera module of the present invention can be configured in combination to achieve corresponding effects.

[0113] According to the above implementation modes, specific embodiments are proposed below and described in detail with reference to the accompanying drawings.

[0118] The axial driver 12 is used to drive the optical imaging lens 111 to move along a direction parallel to the optical axis OL, and the axial driver 12 includes a housing 121 , a base 122 , two driving coils 123 and two driving magnets 124 .

[0119] The base 122 is connected to the housing 121 and has a through hole 1221 and an inner inclined surface 1222 surrounding the through hole 1221. In addition, the base 122 also has four injection marks 1225, which are respectively located at four chamfered corners of the base 122.

[0120] The single component 112 of the imaging lens module 11 is movably disposed between the housing 121 and the base 122 of the axial driver 12, so that the optical imaging lens 111 is disposed in the housing 121, and the optical axis OL of the imaging lens module 11 passes through the geometric center of the through hole 1221 of the base 122. The single component 112 is movably disposed between the housing 121 and the base 122 via the upper spring sheet 13 and the lower spring sheet 14. In detail, the upper spring piece 13 and the lower spring piece 14 each include an inner fixing portion, an outer fixing portion, and an elastic portion (not separately labeled) connected between the inner fixing portion and the outer fixing portion, the inner fixing portion of the upper spring piece 13 is disposed on the single component 112 and the outer fixing portion of the upper spring piece 13 is assembled to the inside of the housing 121 so that the single component 112 can move relative to the housing 121, and the inner fixing portion of each lower spring piece 14 is disposed on the single component 112 and the outer fixing portion of each lower spring piece 14 is assembled to the base 122 so that the single component 112 can move relative to the base 122. In this embodiment, the minimum inner diameter Din of the through hole 1221 is smaller than the maximum outer diameter Dout of the imaging lens module 11.

[0121] The driving coil 123 is disposed on two opposite outer sides of the single component 112, and the driving magnet 124 is fixed in the housing 121 and faces the driving coil 123 along a direction perpendicular to the optical axis OL, wherein the driving magnet 124 and the driving coil 123 are both symmetrically disposed about the optical axis OL. Thus, the electromagnetic interaction between the driving magnet 124 and the driving coil 123 can generate a driving magnetic force to drive the single component 112 to move along a direction parallel to the optical axis OL. In this embodiment, the two sets of driving magnets 124 and the driving coil 123 of the axial driver 12 are respectively disposed on two opposite sides of the imaging lens module 11 to jointly generate a resultant force parallel to the optical axis OL to be applied to the single component 112 of the imaging lens module 11, so that the single component 112 and the optical imaging lens 111 therein can move together along a direction parallel to the optical axis OL.

[0122] The image sensing module 15 is disposed on the image side of the axial driver 12 , and includes a circuit board 151 , a plurality of elastic wires 152 , an image sensor 153 , an image stabilization driver 154 and a substrate 155 .

[0123] The image sensor 153 is used to convert the light passing through the imaging lens module 11 into an image signal. In this embodiment, the image sensor 153 is connected to the circuit board 151 through the elastic wire 152, so that the image sensor 153 can move relative to the circuit board 151; that is, the elastic wire 152 can provide the image sensor 153 with the freedom to move in a direction perpendicular to the optical axis OL. In addition, the elastic wire 152 can also be used to transmit the electrical signal of the image sensor 153.

[0124] The image stabilization driver 154 is used to drive the image sensor 153 to move along at least one direction perpendicular to the optical axis OL. In this embodiment, the image stabilization driver 154 is a voice coil motor, which includes four stabilization magnets 1541 and four stabilization coils 1542, wherein the stabilization magnets 1541 are disposed on the side of the substrate 155 facing the image sensor 153, and the stabilization coils 1542 are disposed on the side of the image sensor 153 facing the substrate 155, and the stabilization magnets 1541 are respectively facing one of the stabilization coils 1542 in the direction parallel to the optical axis OL. Figure 7 As shown, four stabilizing coils 1542 are respectively disposed around the image sensor 153, and the electromagnetic interaction between the four stabilizing coils 1542 and the stabilizing magnets 1541 can generate a direction perpendicular to the optical axis OL (eg Figure 7 The driving force (in the middle arrow) is applied to the stabilizing coil 1542, so as to drive the image sensor 153 to move along the direction perpendicular to the optical axis OL through the stabilizing coil 1542.

[0125] The substrate 155 is fixed on the circuit board 151 and faces the axial driver 12, and the substrate 155 and the base 122 of the axial driver 12 are supported against each other. In addition, the substrate 155 has an opening 1551 to expose the image sensor 153 disposed on the circuit board 151, so that the light passing through the imaging lens module 11 can be incident on the image sensor 153. In this embodiment, the base 122 of the axial driver 12 includes two terminal portions 1223 extending toward the substrate 155 of the image sensor module 15 along the direction of the optical axis OL, wherein the terminal portions 1223 are welded to the substrate 155 for providing a driving signal to the axial driver 12.

[0126] The base 122 of the axial driver 12 has a first axial connection structure 1224, and the substrate 155 of the image sensing module 15 has a second axial connection structure 1552, wherein the shapes of the first axial connection structure 1224 and the second axial connection structure 1552 are both annular. The first axial connection structure 1224 is connected to the second axial connection structure 1552, so that the relative positions between the imaging lens module 11 and the image sensing module 15 are aligned along the direction of the optical axis OL. The first axial connection structure 1224 is located at a bottom of the base 122 facing the image sensing module 15, and the first axial connection structure 1224 protrudes from the bottom toward the image sensing module 15; the second axial connection structure 1552 is located at a top of the substrate 155 facing the axial driver 12, and the second axial connection structure 1552 is recessed from the top toward the direction away from the axial driver 12.

[0127] like Figure 6 As shown, the first axial connection structure 1224 includes a plane 12241 and an inclined surface 12242 connected to each other and forming an angle, and the second axial connection structure 1552 includes a plane 15521 and an inclined surface 15522 connected to each other and forming an angle. The plane 12241 and the inclined surface 12242 of the first axial connection structure 1224 correspond to the plane 15521 and the inclined surface 15522 connected to the second axial connection structure 1552, respectively. The plane 12241 and the plane 15521 are substantially perpendicular to the optical axis OL to maintain the distance between the imaging lens module 11 and the image sensor 153 and prevent skew, while the inclined surface 12242 and the inclined surface 15522 are used to align the optical axis OL of the imaging lens module 11 to the geometric center of the image sensor 153. The inclined surface 15522 of the second axial connection structure 1552 surrounds the inclined surface 12242 of the first axial connection structure 1224.

[0128] In this embodiment, the first axial connection structure 1224 and the second axial connection structure 1552 both have the optical axis OL passing through their centers and both surround the through hole 1221 of the base 122. The first axial connection structure 1224 and the second axial connection structure 1552 are both axially symmetrical with the optical axis OL as the center axis, and the first axial connection structure 1224 and the second axial connection structure 1552 both have smooth surfaces.

[0129] In this embodiment, the area surrounded by the inner slope 1222 of the base 122 gradually shrinks toward the image sensing module 15 along a direction parallel to the optical axis OL, so that the through hole 1221 of the base 122 is formed into a pointed opening, that is, the pointed opening gradually shrinks toward the image sensing module 15 along a direction parallel to the optical axis OL.

[0130] The filter 16 is disposed on the substrate 155 and covers the opening 1551 of the substrate 155.
