The camera device 200 can be installed in an electronic device as a camera component. For example, the electronic device can be such as a smart phone, wearable devices, tablet computers, cameras, or tablet devices, monitors, etc.

[0073] See also Figures 3 to 6 , Figure 3 is a top view schematic diagram of the lens module 100, Figure 4 is a front exploded view of the lens module 100, and Figures 5 and 6Schematic cross-sectional view of the lens module 100. In some embodiments, the lens module 100 includes a substrate 10, a photosensitive component 20, a support member 30, a first lens 40, an actuator 50, an outer ring member 60 and a second lens 70. The support member 30 has a first opening 301 (through hole). The actuator 50 has a second opening 501 (through hole). The two sides of the outer ring member 60 respectively include a concave structure 603 facing the first lens 40 and a third opening 601 (through hole). The outer ring member 60 has a receiving space 602 located between the concave structure 603 and the third opening 601.

[0074] In some exemplary embodiments, the lens module 100 is composed of a substrate 10, a photosensitive component 20, a support member 30, a first lens 40, an actuator 50, an outer ring member 60, and a second lens 70. The photosensitive component 20 is located on the substrate 10. The support member 30 is disposed on the substrate 10 and covers the photosensitive component 20, and the support member 30 has a first opening 301. The first lens 40 is disposed at the first opening 301 of the support member 30 corresponding to the photosensitive component 20, and the photosensitive component 20 is located between the first lens 40 and the substrate 10. The actuator 50 is located on the support member 30, and the actuator 50 has a second opening 501. The outer ring member 60 is disposed at the second opening 501 of the actuator 50, and the two sides of the outer ring member 60 respectively include a concave structure 603 and a third opening 601 facing the first lens 40. The outer ring member 60 has a receiving space 602 located between the concave structure 603 and the third opening 601. The second lens 70 is disposed in the accommodation space 602 of the outer ring 60 and is located between the first lens 40 and the third opening 601 of the outer ring 60 .

[0075] One end of the substrate 10 is provided with a photosensitive component 20 and a support member 30, so that it is covered by components such as the first lens 40, the actuator 50, the outer ring member 60, and the second lens 70, and the other end extends outward to be connected to an external device. For example, when the lens module 100 is applied to a camera device 200, one end of the substrate 10 is provided with components such as the substrate 10, the photosensitive component 20, the support member 30, the first lens 40, the actuator 50, the outer ring member 60, and the second lens 70, and the other end is located on the housing 80 of the camera device 200. Figure 1 and 2 In some embodiments, the substrate 10 may be a flexible substrate or a silicon substrate.

[0076] The photosensitive component 20 is located on the substrate 10. Here, the substrate 10 has a conductive function, and the photosensitive component 20 is electrically connected to the substrate 10. For example, the photosensitive component 20 is coupled to the conductive circuit of the substrate 10, and through the circuit routing inside the substrate 10, the electrical signal from the circuit outside the camera device 200 can be transmitted to the photosensitive component 20. In some embodiments, the photosensitive component 20 can be a CMOS image sensor (CIS). In some embodiments, the photosensitive component 20 can be a flip chip package or electrically connected to the substrate 10 by surface mounting technology (SMT). In some embodiments, the photosensitive component 20 includes a photosensitive area and a non-photosensitive area (not shown in the figure), and the non-photosensitive area is located outside the photosensitive area.

[0077] Furthermore, the photosensitive element 20 can convert the optical image signal irradiated into the photosensitive element 20 into an electrical image signal. For example, the optical image signal is emitted from the outside of the camera device 200, passes through the protective cover 90, the second lens 70, and the first lens 40, and then enters the photosensitive area of ​​the photosensitive element 20, wherein the photosensitive area is an area for optical sensing.

[0078] The support member 30 is disposed on the substrate 10 and covers the photosensitive component 20. For example. The support member 30 is disposed on the substrate 10 outside the photosensitive component 20. Here, the support member 30 is used to support the first lens 40 and the actuator 50. In some embodiments, the support member 30 is an annular structure, which is disposed on the substrate 10 outside the photosensitive component 20. In some embodiments, the number of the support members 30 can be adjusted according to the actual application, that is, the number of the support members 30 can be one or more.

[0079] The support member 30 has a first opening 301 located above the photosensitive area of ​​the photosensitive component 20 , so that an external light source can enter the photosensitive component 20 through the first opening 301 .

[0080] In some embodiments, the support member 30 includes a fixing portion 31 and a bearing portion 33. One end of the fixing portion 31 is disposed on the substrate 10, and the other end is connected to the bearing portion 33. In other words, the fixing portion 31 and the bearing portion 33 are perpendicular to each other. In addition, the fixing portion 31 is disposed on the substrate 10 around the photosensitive component 20, and the bearing portion 33 is located above the periphery of the photosensitive area (i.e., the non-photosensitive area) of the photosensitive component 20. In some embodiments, the fixing portion 31 and the bearing portion 33 can be integrally formed, or can be independent components separated from each other and connected to each other through assembly to form the support member 30.

[0081] In some embodiments, the carrying portion 33 has a first surface 331, a second surface 332 and a side surface 333. Figures 7 to 13As shown. The first surface 331 is the inner wall surface and is adjacent to the surface of the bearing portion 33 of the photosensitive component 20, and the second surface 332 is the outer wall surface and is adjacent to the surface of the bearing portion 33 of the outer ring member 60. The first surface 331 and the second surface 332 are parallel to each other and connected by the side surface 333 (i.e., the hole wall of the first opening 301). In addition, the side surface 333 vertically connects the first surface 331 and the second surface 332.

[0082] In other embodiments, the support member 30 includes a limiting portion (defined as a first limiting portion 35) in addition to the fixing portion 31 and the bearing portion 33. The first limiting portion 35 is connected to the bearing portion 33. For example, the first limiting portion 35 is vertically disposed on the first surface 331 or the second surface 332 of the bearing portion 33. In some embodiments, the fixing portion 31, the bearing portion 33, and the first limiting portion 35 can be integrally formed, or can be separate independent components that are connected to each other through assembly to form the support member 30.

[0083] In some other embodiments, the support member 30 includes a plurality of limiting portions (defined as a first limiting portion 35 and a second limiting portion 37) in addition to the fixing portion 31 and the bearing portion 33. The first limiting portion 35 and the second limiting portion 37 are both connected to the bearing portion 33. For example, the first limiting portion 35 is vertically disposed on the first surface 331 or the second surface 332 of the bearing portion 33, and the second limiting portion 37 is vertically disposed on the second surface 332 of the bearing portion 33, and the axis of the second limiting portion 37 vertically disposed on the second surface 332 is located outside the outer ring member 60. In some embodiments, the fixing portion 31, the bearing portion 33, the first limiting portion 35 and the second limiting portion 37 can be integrally formed, or can be independent components separated from each other and connected to each other through assembly to form the support member 30.

[0084] The first lens 40 is disposed in the first opening 301 of the support member 30 corresponding to the photosensitive component 20. Thus, the photosensitive component 20 is located between the first lens 40 and the substrate 10. In some embodiments, the first lens 40 includes a lens body 41 and a rib 43. Figures 7 to 13 The lens body 41 is located on the photosensitive component 20, one end of the rib 43 is connected to the lens body 41, and the other end thereof contacts the support member 30. In some embodiments, the minimum distance between the lower edge of the lens body 41 and the photosensitive component 20 is not less than 0 mm.

[0085] from Figure 4 From the perspective of the first lens 40, the shape is circular, but it can also be elliptical, square or any curved surface, but it is not restrictive. Figure 5 and 6From the perspective of the present invention, the first lens 40 may be, but is not limited to, a flat lens, a spherical convex lens, a spherical concave lens, a parabolic convex lens, a parabolic concave lens or a free-form lens. In some embodiments, the first lens 40 may be made of glass or plastic.

[0086] See also Figure 6 In some embodiments, the first lens 40, the substrate 10 and the support member 30 can form a closed space CS. For example, the fixing portion 31 of the support member 30 surrounds the photosensitive component 20 and is disposed on the substrate 10 with one end, and the other end is connected to the bearing portion 33. The bearing portion 33, which is perpendicular to the fixing portion 31, is located above the periphery of the photosensitive area of ​​the photosensitive component 20, and the first lens 40 contacts the other end of the bearing portion 33 away from the fixing portion 31. In other words, the first lens 40 covers the photosensitive area of ​​the photosensitive component 20, and the bearing portion 33 of the support member 30 covers the non-photosensitive area of ​​the photosensitive component 20. Thereby, the first lens 40, the substrate 10 and the support member 30 form a closed space CS.

[0087] In some embodiments, the support member 30 includes a fixing portion 31 and a carrying portion 33, and the support member 30 supports or fixes the first lens 40 with the carrying portion 33. For example, the rib 43 of the first lens 40 is fixed to the second surface 332 or the side surface 333 of the carrying portion 33 by adhesive or other connecting means, so that the first lens 40, the substrate 10 and the support member 30 form a closed space CS. Based on this, the carrying portion 33 can be used to support or fix the first lens 40 and prevent foreign dust from entering the closed space CS.

[0088] In other embodiments, the support member 30 includes a first limiting portion 35 in addition to the fixing portion 31 and the carrying portion 33, and the first limiting portion 35 is vertically disposed on the first surface 331 or the second surface 332 of the carrying portion 33. The first lens 40 contacts the carrying portion 33 and the first limiting portion 35, so that the first lens 40, the substrate 10 and the support member 30 form a closed space CS. Here, the first limiting portion 35 can be used to limit and / or strengthen the support of the first lens 40, or as a baffle to block external pollution.

[0089] In some other embodiments, the support member 30 includes a first limiting portion 35 and a second limiting portion 37 in addition to the fixing portion 31 and the bearing portion 33. The first limiting portion 35 is vertically disposed on the first surface 331 or the second surface 332 of the bearing portion 33, and the second limiting portion 37 is vertically disposed on the second surface 332 of the bearing portion 33. The first lens 40 contacts the bearing portion 33 and the first limiting portion 35, so that the first lens 40, the substrate 10 and the support member 30 form a closed space CS, and the second limiting portion does not contact the first lens 40. Here, the first limiting portion 35 can be used to limit and / or support the first lens 40, and the second limiting portion 37 can be used as a baffle and a limiting outer ring member 60 to block external contamination.

[0090] The actuator 50 is located on the support member 30. Here, the actuator 50 is used to drive the outer ring member 60 to move the second lens 70 in a direction perpendicular to the photosensitive component 20 for focusing. In some embodiments, the actuator 50 may have an optical image stabilization function. The actuator 50 may be a voice coil motor (VCM), but is not limited thereto. In some embodiments, the actuator 50 may be a stepper motor, a micro piezoelectric actuator, or a shape memory alloy motor (SMA).

[0091] The actuator 50 has a second opening 501. Specifically, the actuator 50 may be a ring-shaped or frame-shaped structure to form the second opening 501. Figure 4 The outer ring 60 can be disposed in the second opening 501 of the actuator 50 and connected to the side wall of the actuator 50 forming the second opening 501. In some embodiments, the outer ring 60 is moved up and down in the second opening 501 by an actuator bracket (not shown in the figure).

[0092] The outer ring 60 is disposed at the second opening 501 of the actuator 50, and the two sides of the outer ring 60 respectively include a concave structure 603 facing the first lens 40 and a third opening 601. The outer ring 60 has an accommodation space 602 located between the concave structure 603 and the third opening 601. Figure 5 and Figure 6 The concave structure 603 is located on one side adjacent to the first lens 40, and the third opening 601 is located on the other side away from the first lens 40. The shape of the accommodation space 602 can be arc-shaped, concave or stepped, so as to be provided to at least one second lens 70.

[0093] See also Figure 6 The concave structure 603 includes an inner top surface 6031 and at least one inner side wall 6032. In addition, the inner top surface 6031 has a through opening 60311 connected to the accommodating space 602, and the at least one inner side wall 6032 is vertically connected to the inner top surface 6031. Specifically, the end of the concave structure 603 away from the first lens 40 is the inner top surface 6031 and its through opening 60311.

[0094] In some embodiments, the concave structure 603 of the outer ring 60 covers the first lens 40 , and the inner sidewall 6032 of the concave structure 603 is close to but does not contact the second surface 332 of the carrying portion 33 .

[0095] In some embodiments, there is a first height difference h1 between the rib 43 of the first lens 40 and the inner top surface 6031 of the concave structure 603, such as Figure 6As shown. For example, the first height difference h1 is not less than 0.10 mm and less than 0.55 mm. For example, the first height difference h1 is 0.10 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.20 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, 0.30 mm, 0.31 . In one example, when the outer ring 60 is located at the initial position of the actuator 50 (i.e., the outer ring 60 and the support member 30 have the shortest distance on the virtual vertical line), the first height difference h1 is 0.27±0.02 mm.

[0096] See also Figure 6 In some embodiments, the concave structure 603 has a first width L1, the first lens 40 has a second width L2, and the first width L1 is greater than the second width L2.

The housing 80 has a through hole 801 on one side. The protective cover 90 is disposed on the through hole 801 of the housing 80 and has a light filtering function. The substrate 10 is disposed on a side of the housing 80 away from the through hole 801. The photosensitive component 20 is located on the substrate 10. The support member 30 is disposed on the substrate 10 and covers the photosensitive component 20, and the support member 30 has a first opening 301. The first lens 40 is disposed on the first opening 301 of the support member 30 corresponding to the photosensitive component 20, and the photosensitive component 20 is located between the first lens 40 and the substrate 10.

In addition, the closed space CS formed by the first lens 40, the support member 30 and the substrate 10 can avoid dust pollution. In any embodiment, the protective cover with a filter function of the camera device 200 can replace the traditional filter and reduce the assembly parts in the traditional lens module 100, thereby reducing the height of the entire module while maintaining the original function.
