[0070] Unless otherwise specified as electrical connection, the terms used in the following embodiments regarding connections can refer to physical connections, or direct or indirect connections between physical components. It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0071] Please see Figure 1 and Figure 2 The lens module 100 can be applied to the camera device 200. In some embodiments, the camera device 200 includes a housing 80, a protective cover 90, and a lens module 100. The housing 80 has a through hole 801 on one side, and the protective cover 90 is disposed in the through hole 801 of the housing 80. The lens module 100 is disposed on the side of the housing 80 away from the through hole 801 via a substrate 10.

[0072] For example, lens module 100 can be used as a front-facing camera, main camera, wide-angle lens, or telephoto lens in a mobile phone. Camera device 200 can be installed in an electronic device as a camera component. For example, the electronic device can be a smartphone, wearable devices, a tablet, a camera, a tablet device, or a monitor.

[0073] Please see Figures 3 to 6 , Figure 3 A top-view diagram of lens module 100. Figure 4 This is an exploded view of the front of the lens module 100. Figures 5 to 6This is a cross-sectional schematic diagram 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 outer ring member 60 has a concave structure 603 facing the first lens 40 and a third opening 601 (through hole) on each side. The outer ring member 60 has an accommodating space 602 located between the concave structure 603 and the third opening 601.

[0074] In some examples, 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 corresponding to the photosensitive component 20 in the first opening 301 of the support member 30, 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 in the second opening 501 of the actuator 50, and the outer ring member 60 has a concave structure 603 facing the first lens 40 and a third opening 601 on each side. The outer ring member 60 has an accommodating space 602 located between the concave structure 603 and the third opening 601. The second lens 70 is disposed within the accommodating space 602 of the outer ring member 60 and is located between the first lens 40 and the third opening 601 of the outer ring member 60.

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

[0076] A photosensitive component 20 is located on a substrate 10. The substrate 10 is conductive, and the photosensitive component 20 is electrically connected to the substrate 10. For example, the photosensitive component 20 is coupled to the conductive lines of the substrate 10 and, through circuit traces within the substrate 10, allows electrical signals from circuits outside the imaging device 200 to be transmitted to the photosensitive component 20. In some embodiments, the photosensitive component 20 may be a CMOS image sensor (CIS). In some embodiments, the photosensitive component 20 may be a flip-chip package or electrically connected to the substrate 10 using surface-mount technology (SMT). In some embodiments, the photosensitive component 20 includes a photosensitive area and a non-photosensitive area (not shown in the figures), with the non-photosensitive area located around the photosensitive area.

[0077] Furthermore, the photosensitive component 20 can convert the optical image signal incident upon it into an electrical image signal. For example, the optical image signal originates from outside 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 component 20, where the photosensitive area is the region used for optical sensing.

[0078] A support member 30 is disposed on the substrate 10 and covers the photosensitive assembly 20. For example, the support member 30 is disposed on the substrate 10 outside the photosensitive assembly 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 has a ring structure, which is disposed around the substrate 10 outside the photosensitive assembly 20. In some embodiments, the number of support members 30 can be adjusted according to the actual application, that is, the number of 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, allowing external light sources to 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 supporting portion 33. One end of the fixing portion 31 is disposed on the substrate 10, and the other end is connected to the supporting portion 33. In other words, the fixing portion 31 and the supporting portion 33 are perpendicular to each other. Furthermore, the fixing portion 31 is disposed around the photosensitive component 20 on the substrate 10, and the supporting portion 33 is located above the periphery (i.e., the non-photosensitive area) of the photosensitive component 20. In some embodiments, the fixing portion 31 and the supporting portion 33 may be integrally formed, or they may be separate independent components that are connected to each other by assembly to form the support member 30.

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

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

[0083] In some embodiments, the support member 30, in addition to the fixing part 31 and the bearing part 33, further includes a plurality of limiting parts (defined as a first limiting part 35 and a second limiting part 37). Both the first limiting part 35 and the second limiting part 37 are connected to the bearing part 33. For example, the first limiting part 35 is perpendicularly disposed on the first surface 331 or the second surface 332 of the bearing part 33, while the second limiting part 37 is perpendicularly disposed on the second surface 332 of the bearing part 33, and its axis perpendicularly disposed on the second surface 332 is located outside the outer ring member 60. In some embodiments, the fixing part 31, the bearing part 33, the first limiting part 35, and the second limiting part 37 may be integrally formed, or may be separate independent components 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. Thereby, 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. For example... Figures 7 to 13 As shown. The lens body 41 is located on the photosensitive assembly 20, with one end of the rib 43 connected to the lens body 41 and the other end contacting the support member 30. In some embodiments, the minimum distance between the lower edge of the lens body 41 and the photosensitive assembly 20 is not less than 0 mm.

[0085] from Figure 4 The first lens 40 is circular, but it can also be elliptical, square, or any curved surface; it is not a limitation. Figure 5 and 6The first lens 40 can be, but is not limited to, a planar lens, a spherical convex lens, a spherical concave lens, a parabolic convex lens, a parabolic concave lens, or a freeform lens. In some embodiments, the first lens 40 can be made of glass or plastic.

[0086] Please see 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 assembly 20 and is disposed at one end on the substrate 10, while the other end is connected to the carrier portion 33. The carrier portion 33, which is perpendicular to the fixing portion 31, is located above the periphery of the photosensitive area of ​​the photosensitive assembly 20, and the first lens 40 contacts the other end of the carrier portion 33 away from the fixing portion 31. In other words, the first lens 40 covers the photosensitive area of ​​the photosensitive assembly 20, while the carrier portion 33 of the support member 30 covers the non-photosensitive area of ​​the photosensitive assembly 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 comprises a fixing portion 31 and a bearing portion 33, with the bearing portion 33 supporting or fixing the first lens 40. For example, the rib 43 of the first lens 40 is fixed to the second surface 332 or side surface 333 of the bearing portion 33 by adhesive or other connecting means, thereby forming a closed space CS with the first lens 40, the substrate 10, and the support member 30. Therefore, the bearing portion 33 can be used to support or fix the first lens 40 and prevent external dust from entering the closed space CS.

[0088] In other embodiments, in addition to the fixing part 31 and the bearing part 33, the support member 30 further includes a first limiting part 35, and the first limiting part 35 is vertically disposed on the first surface 331 or the second surface 332 of the bearing part 33. The first lens 40 contacts the bearing part 33 and the first limiting part 35, thereby forming a closed space CS with the first lens 40, the substrate 10 and the support member 30. Here, the first limiting part 35 can be used to limit and / or reinforce the support of the first lens 40, or as a baffle to block external contamination.

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

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

[0091] The actuator 50 has a second opening 501. Specifically, the actuator 50 can be an annular or frame-shaped structure to form the second opening 501. See also Figure 4 The outer ring 60 may be disposed in the second opening 501 of the actuator 50 and connected to the sidewall of the actuator 50 forming the second opening 501. In some embodiments, the outer ring 60 is displaced vertically in the second opening 501 by means of an actuation bracket (not shown in the figure).

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

[0093] Please see Figure 6 The concave structure 603 includes an inner top surface 6031 and at least one inner sidewall 6032. The inner top surface 6031 has an opening 60311 communicating with the accommodating space 602, and the at least one inner sidewall 6032 is perpendicularly connected to the inner top surface 6031. Specifically, the end of the concave structure 603 furthest from the first lens 40 is the inner top surface 6031 and its 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 approaches but does not contact the second surface 332 of the support portion 33.

[0095] In some embodiments, a first height difference h1 exists 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 mm. The dimensions are 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, 0.36 mm, 0.37 mm, 0.38 mm, 0.39 mm, 0.40 mm, 0.41 mm, 0.42 mm, 0.43 mm, 0.44 mm, 0.45 mm, 0.46 mm, 0.47 mm, 0.48 mm, 0.49 mm, 0.50 mm, 0.51 mm, 0.52 mm, 0.53 mm, or 0.54 mm. In one example, when the outer ring 60 is in the initial position of the actuator 50 (i.e., the outer ring 60 and the support 30 are at their closest distance on the virtual vertical line), the first height difference h1 is 0.27 ± 0.02 mm.

[0096] Please see 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. For example, the lengths of the first width L1 and the second width L2 are not less than 0.10 mm and not greater than 15 mm. In one exemplary example, the first width L1 is 6.5 ± 0.02 mm, and the second width L2 is 5.6 ± 0.02 mm.

[0097] The second lens 70 is disposed within the accommodating space 602 of the outer ring member 60, and is located between the first lens 40 and the third opening 601 of the outer ring member 60. In other words, optical signals from the outside will pass through the third opening 601, the second lens 70 and the first lens 40 in sequence before being received by the photosensitive component 20.

[0098] from Figure 4 The second lens 70 is circular in shape, but it can also be elliptical, square, or any curved surface; it is not a limitation. Figure 5 and 6 The second lens 70 can be, but is not limited to, a planar lens, a spherical convex lens, a spherical concave lens, a parabolic convex lens, a parabolic concave lens, or a freeform lens. In some embodiments, the second lens 70 can be made of glass or plastic.

[0099] In some embodiments, within the accommodating space 602 of the outer ring member 60 of the second lens 70, a portion of the second lens 70 passes through the opening 60311 and is located in the concave structure 603, and a second height difference h2 exists between the lower surface of the second lens 70 and the lens body 41 of the first lens 40, such as... Figure 6 As shown. For example, the second height difference h2 is not less than 0.1 mm and not greater than 0.5 mm. For example, the second height difference h2 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. The height difference is 0.25 mm, 0.30 mm, 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, 0.36 mm, 0.37 mm, 0.38 mm, 0.39 mm, 0.40 mm, 0.41 mm, 0.42 mm, 0.43 mm, 0.44 mm, 0.45 mm, 0.46 mm, 0.47 mm, 0.48 mm, 0.49 mm, or 0.50 mm. In one example, when the outer ring 60 is in the initial position of the actuator 50 (i.e., the outer ring 60 and the support 30 are at their closest distance on the virtual vertical line), the second height difference h2 is 0.25 mm.

[0100] Please see Figure 5 and Figure 6In some embodiments, a photosensitive element 20 and a support member 30 are provided on the substrate 10. The support member 30 is vertically disposed on the substrate 10 outside the photosensitive element 20 with its fixing portion 31, and surrounds the periphery of the photosensitive element 20. The support member 30 includes a fixing portion 31, a bearing portion 33, and a first limiting portion 35. The first lens 40 is disposed on the first limiting portion 35 and contacts the side surface 333 of the bearing portion 33, thereby forming a closed space CS with the first lens 40, the support member 30, and the substrate 10, and preventing external dust from entering and contaminating the photosensitive element 20. An actuator 50 with a second opening 501 is disposed on the bearing portion 33 of the support member 30 and connected to an outer ring member 60. The outer ring member 60 is disposed in the second opening 501 of the actuator 50, and its side facing the first lens 40 is a concave structure 603, which covers the first lens 40. The outer ring 60 has a third opening 601 on the opposite side of the first lens 40, and a receiving space 602 is formed between the third opening 601 and the concave structure 603, within which the second lens 70 is housed. The lower edge of the inner wall 6032 of the concave structure 603 approaches but does not contact the second surface 332 of the supporting portion 33. The lower edge of the second lens 70 passes through the opening 60311 of the concave structure 603, approaches but does not contact the lens body 41 of the first lens 40. Furthermore, the first limiting portion 35 of the support member 30 has an axis perpendicular to the second surface 332 located inside the outer ring 60, that is, this axis is located between the inner wall 6032 of the concave structure 603 and the rib 43 of the first lens 40. In this way, the first limiting portion 35 can reduce the probability of external dust entering the outer ring 60 and contaminating the first lens 40.

[0101] Please see again Figure 6 , combined Figures 7 to 13 . Figure 6 The dashed H-shaped box in the middle indicates the relative positions of the first lens 40, the support 30, and the outer ring 60. Figures 7 to 13 These are schematic diagrams showing the relative positions of the support member 30 (i.e., the first to the seventh embodiments) with the first lens 40 and the outer ring member 60, respectively, in different implementation configurations. Figure 6 The implementation state of the support member 30 shown in the figure is as follows Figure 12 The sixth implementation of the support component 30.

[0102] Please see Figure 7In some embodiments of the support member 30 of the first embodiment, the support member 30 includes a fixing part 31 (not shown) and a bearing part 33, and the outer side of the rib 43 of the first lens 40 is fixed to the side surface 333 of the bearing part 33. The concave structure 603 of the outer ring member 60 covers the first lens 40 and part of the bearing part 33, and the lower edge of the inner sidewall 6032 of the outer ring member 60 is close to but does not contact the second surface 332 of the bearing part 33. Here, the inner sidewall 6032 of the outer ring member 60 can reduce the probability of external dust entering the concave structure 603 and contaminating the first lens 40, and since the first lens 40 can be fixed to the side surface 333 of the bearing part 33, the distance between the inner top surface 6031 and the second surface 332 of the concave structure 603 can be reduced.

[0103] Please see Figure 8 In some embodiments of the support member 30 in the second embodiment, the support member 30 includes a fixing part 31 (not shown in the figure), a bearing part 33, and a first limiting part 35, and the first limiting part 35 is vertically disposed on the first surface 331 of the bearing part 33. The outer side of the rib 43 of the first lens 40 is fixed to the side surface 333 of the bearing part 33, and the first limiting part 35 contacts the lower edge of the rib 43 of the first lens 40, thereby strengthening the support and limiting the first lens 40. The concave structure 603 of the outer ring member 60 covers the first lens 40 and part of the bearing part 33, and the lower edge of the inner sidewall 6032 of the outer ring member 60 approaches but does not contact the second surface 332 of the bearing part 33. Therefore, the inner sidewall 6032 of the outer ring 60 can reduce the probability of foreign dust entering the concave structure 603 and contaminating the first lens 40, and since the first lens 40 can be supported by the first limiting part 35, the distance between the inner top surface 6031 and the second surface 332 of the concave structure 603 can be reduced.

[0104] Please see Figure 9In some embodiments of the support member 30 of the third embodiment, the support member 30 includes a fixing part 31 (not shown in the figure), a bearing part 33, a first limiting part 35, and a second limiting part 37. The outer side of the rib 43 of the first lens 40 is fixed to the side surface 333 of the bearing part 33. The first limiting part 35 is vertically disposed on the first surface 331 of the bearing part 33 and contacts the lower edge of the rib 43 of the first lens 40, thereby strengthening the support and limiting the first lens 40. The second limiting part 37 is vertically disposed on the second surface 332 of the bearing part 33, and the axis of the second limiting part 37 perpendicular to the second surface 332 is located on the outer side of the outer ring member 60. The concave structure 603 of the outer ring member 60 covers the first lens 40, the first limiting part 35, and part of the bearing part 33. The lower edge of the inner sidewall 6032 of the outer ring member 60 is close to but does not contact the second surface 332 of the bearing part 33, and the second limiting part 37 is provided on the outer side of the outer ring member 60. Therefore, the inner sidewall 6032 of the outer ring 60 and the second limiting part 37 can reduce the probability of foreign dust entering the concave structure 603 and contaminating the first lens 40. Since the first lens 40 can be supported by the first limiting part 35, the distance between the inner top surface 6031 and the second surface 332 of the concave structure 603 can be reduced.

[0105] Please see Figure 10 In some embodiments of the support member 30 of the fourth embodiment, the support member 30 includes a fixing portion 31 (not shown) and a bearing portion 33, and the lower edge of the rib 43 of the first lens 40 contacts the second surface 332 of the bearing portion 33. The concave structure 603 of the outer ring member 60 covers the first lens 40 and part of the bearing portion 33, and the lower edge of the inner sidewall 6032 of the outer ring member 60 is close to but does not contact the second surface 332 of the bearing portion 33. In this way, the inner sidewall 6032 of the outer ring member 60 can reduce the probability of foreign dust entering the concave structure 603 and contaminating the first lens 40.

[0106] Please see Figure 11In some embodiments of the fifth embodiment of the support member 30, the support member 30 includes a fixing part 31 (not shown in the figures), a bearing part 33, and a first limiting part 35. The lower edge of the rib 43 of the first lens 40 contacts the second surface 332 of the bearing part 33, and the first limiting part 35 is perpendicularly disposed on the second surface 332 of the bearing part 33. Furthermore, the axis of the first limiting part 35 perpendicular to the second surface 332 is located outside the rib 43 of the first lens 40 and outside the outer ring member 60. The concave structure 603 of the outer ring member 60 covers the first lens 40 and part of the bearing part 33. The lower edge of the inner sidewall 6032 of the outer ring member 60 is close to but does not contact the second surface 332 of the bearing part 33, and the first limiting part 35 is provided on the outer side of the outer ring member 60. Therefore, the inner sidewall 6032 of the outer ring member 60 and the first limiting part 35 can reduce the probability of foreign dust entering the concave structure 603 and contaminating the first lens 40, and the first limiting part 35 located on the outer side of the outer ring member 60 can limit the outer ring member 60.

[0107] Please see Figure 12 In some embodiments of the support member 30 of the sixth embodiment, the support member 30 includes a fixing part 31 (not shown in the figures), a bearing part 33, and a first limiting part 35. The lower edge of the rib 43 of the first lens 40 contacts the second surface 332 of the bearing part 33, while the first limiting part 35 is perpendicularly disposed on the second surface 332 of the bearing part 33. Furthermore, the axis of the first limiting part 35 perpendicular to the second surface 332 is located on the outer side of the rib 43 of the first lens 40 and the inner side of the outer ring member 60. The concave structure 603 of the outer ring member 60 covers the first lens 40, the first limiting part 35, and part of the bearing part 33. The lower edge of the inner sidewall 6032 of the outer ring member 60 approaches but does not contact the second surface 332 of the bearing part 33 and the surface of the first limiting part 35 facing the concave structure 603. Therefore, the inner wall 6032 of the outer ring 60 and the first limiting part 35 can reduce the probability of foreign dust entering the concave structure 603 and contaminating the first lens 40, and the first limiting part 35 located inside the outer ring 60 can limit the first lens 40.

[0108] Please see Figure 13In some embodiments of the support member 30 of the seventh embodiment, the support member 30 includes a fixing part 31 (not shown in the figure), a bearing part 33, a first limiting part 35, and a second limiting part 37. The lower edge of the rib 43 of the first lens 40 contacts the second surface 332 of the bearing part 33, while the first limiting part 35 and the second limiting part 37 are perpendicularly disposed on the second surface 332 of the bearing part 33. Furthermore, the axis of the first limiting part 35 perpendicular to the second surface 332 is located outside the rib 43 of the first lens 40 and inside the outer ring 60, while the axis of the second limiting part 37 perpendicular to the second surface 332 is located outside the rib 43 of the first lens 40 and outside the outer ring 60. The concave structure 603 of the outer ring 60 covers the first lens 40, the first limiting part 35, and part of the bearing part 33, and the second limiting part 37 is provided on the outer side of the outer ring 60. The lower edge of the inner sidewall 6032 of the outer ring member 60 approaches but does not contact the second surface 332 of the bearing portion 33 and the surface of the first limiting portion 35 facing the concave structure 603. Here, the inner sidewall 6032 and the first limiting portion 35 of the outer ring member 60 can reduce the probability of external dust entering the concave structure 603 and contaminating the first lens 40, and the second limiting portion 37 located inside the outer ring member 60 can limit the outer ring member 60 and block external dust contamination.

[0109] Please see again Figure 1 and Figure 2 In some embodiments, the imaging device 200 includes a housing 80, a protective cover 90, 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 housing 80 has a through-hole 801 on one side. The protective cover 90 is disposed in the through-hole 801 of the housing 80 and has a light-filtering function. The substrate 10 is disposed on the 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 corresponding to the photosensitive component 20 in the first opening 301 of the support member 30, 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. An outer ring member 60 is disposed at the second opening 501 of the actuator 50, and the outer ring member 60 has a concave structure 603 facing the first lens 40 and a third opening 601 on each side. The outer ring member 60 has an accommodating space 602 located between the concave structure 603 and the third opening 601. The second lens 70 is disposed within the accommodating space 602 of the outer ring member 60, and is located between the first lens 40 and the third opening 601 of the outer ring member 60.

[0110] A protective cover with a filtering function replaces the function of a traditional filter. For example, the protective cover 90 can be a coated flat lens, blue glass, or plastic. In some embodiments, the protective cover 90 has a filter layer. For example, the filter layer of the protective cover 90 can be formed by coating.

[0111] Please see Figure 2 The protective cover 90 is disposed on the through hole 801 of the outer casing 80, while the substrate 10 is disposed on the side of the outer casing 80 away from the through hole 801. Thus, external light sources pass through the protective cover 90 and sequentially enter the third opening 601, the second lens 70, and the first lens 40, and are received by the photosensitive component 20. Furthermore, by replacing the filter traditionally disposed on the support member 30 with the first lens 40, the thickness of the outer ring member 60 where the second lens 70 is located can be shortened, thereby reducing the height of the protective cover 90 and thus lowering the overall module height.

[0112] In summary, the lens module 100 and camera device 200 provided in any embodiment of this application reduce the overall module height and simplify the assembly process by configuring the first lens 40 on different types of support members 30. Furthermore, the enclosed space CS formed by the first lens 40, support member 30, and substrate 10 prevents dust contamination. In any embodiment, the protective cover with a filtering function of the camera device 200 can replace a traditional filter and reduce the number of assembly parts in a traditional lens module 100, thereby reducing the overall module height while retaining the original functionality.
