[0024] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic diagram of a three-dimensional structure of a camera assembly 100 installed on a light-transmitting substrate 200 in an embodiment of the present application. Figure 2for Figure 1 The light-transmitting substrate 200 includes a first side 201 and a second side 202 that are arranged opposite to each other. The camera assembly 100 includes an imaging module 101 and a first connecting member 102, wherein the first connecting member 102 is connected between the imaging module 101 and the first side 201 of the light-transmitting substrate 200, and the first connecting member 102 is provided with a first light-transmitting hole 1021 and a light-shielding portion 1020, wherein the first light-transmitting hole 1021 is arranged corresponding to the lens position of the imaging module 101, and the light-shielding portion 1020 is arranged around the first light-transmitting hole 1021, and the light-shielding portion 1020 is arranged along the imaging module 101. The radial direction of group 101 protrudes from the outer peripheral surface of the imaging module 101, and the imaging module 101 is used to image the scene on the second side 202 of the translucent substrate 200 through the first light-transmitting hole 1021; the side of the imaging module 101 away from the first connecting member 102 is the third side 1011, and the light-shielding portion 1020 is used to block the light entering the translucent substrate 200 from the third side 1011 and entering the imaging module 101 after being reflected by the translucent substrate 200.

[0025] Thus, in the present application, the first connecting member 102 is not light-transmissive, but the first connecting member 102 is provided with a first light-transmitting hole 1021, and the first light-transmitting hole 1021 is arranged corresponding to the lens position of the imaging module 101. The imaging module 101 is used to image the scene on the second side 202 of the light-transmitting substrate 200 through the first light-transmitting hole 1021. Therefore, the first connecting member 102 does not affect the light in front of the imaging module 101 from entering the imaging module 101 for imaging, and the first connecting member 102 does not affect the light in front of the imaging module 101 from entering the imaging module 101 for imaging. A connecting member 102 is provided with a light shielding portion 1020. The light shielding portion 1020 is arranged around the first light-transmitting hole 1021 and protrudes from the outer peripheral surface of the imaging module 101 in the radial direction of the imaging module 101. Therefore, the light shielding portion 1020 can block light from the rear of the imaging module 101, preventing light from entering the imaging module 101, thereby avoiding the imaging glare problem caused by light from the rear of the imaging module 101 entering the imaging module 101. The front of the imaging module 101 refers to the direction in which the camera of the imaging module 101 is facing the captured scene (the scene on the second side 202 of the light-transmitting substrate 200), and the rear of the imaging module 101 refers to the direction opposite to the front of the imaging module 101.

[0026] The imaging module 101 is an electronic device that converts light signals into electrical or digital signals to generate images. The imaging module 101 generally includes a lens, a sensor, an image sensor, and an output interface. The lens is responsible for collecting light and focusing it on the sensor; the sensor converts light into electrical or digital signals; the image processor processes the signal from the sensor, adjusts image quality, and applies image enhancement functions; and the output interface transmits the processed image to a display, storage device, or other device. The imaging module 101 can be widely used in various application scenarios, including photography, videography, medical imaging, machine vision, security, automotive electronics, drones, and medical devices.

[0027] The front of the imaging module 101 refers to the direction in which the camera of the imaging module 101 faces the scene being photographed. Figure 1 In the direction indicated by the arrow A, the rear of the imaging module 101 is the direction opposite to the front of the imaging module 101. Figure 1 Direction indicated by arrow B.

[0028] The imaging module 101 has a square, rectangular, circular or polygonal shape. In this embodiment, the imaging module 101 has a square shape.

[0029] Among them, in some embodiments, the light-transmitting substrate 200 is glass; in other embodiments, the light-transmitting substrate 200 can be polycarbonate (PC), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polystyrene (PS), polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), polyimide (PI), sapphire and quartz, etc.

[0030] In some embodiments, the light-transmitting substrate 200 is double-layer glass. Figure 4 As shown, the light-transmitting substrate 200 includes at least two layers of light-transmitting substrates, and there is a gap between the at least two layers of light-transmitting substrates. In this embodiment, the light-transmitting substrate 200 includes two layers of light-transmitting substrates, and the two layers of light-transmitting substrates include a first light-transmitting substrate 203 and a second light-transmitting substrate 204, wherein the first light-transmitting substrate 203 is connected to the first connecting member 102. The second light-transmitting substrate 204 is located on the side of the first light-transmitting substrate 203 away from the first connecting member 102. There is a gap between the first light-transmitting substrate 203 and the second light-transmitting substrate 204. It should be noted that if there is no first connecting member 102 to block the light from the third side 1011, the light from the third side 1011 will first pass through the first light-transmitting substrate 203, and be reflected on the surface of the second light-transmitting substrate 204 close to the first light-transmitting substrate 203, and then pass through the first light-transmitting substrate 203, and finally enter the imaging module 101. The specific light path diagram is shown in FIG. Figure 4On the contrary, if the light from the third side 1011 is blocked by the first connecting member 102, the light from the third side 1011 will be reflected on the surface of the first connecting member 102 and will not enter the imaging module 101. The specific light path diagram is shown in FIG. Figure 4 In other embodiments, the light-transmitting substrate 200 is a single-layer glass or a multi-layer glass, which is not limited here.

[0031] In some embodiments, the first connecting member 102 is black or other colors with a light transmittance less than a preset threshold. In this embodiment, the first connecting member 102 is black.

[0032] In some embodiments, the first light-transmitting hole 1021 is a circular hole. In other embodiments, the first light-transmitting hole 1021 may be a square hole or a polygonal hole, etc., without limitation herein. When the first light-transmitting hole 1021 is a square hole or a polygonal hole, the inner aperture of the first light-transmitting hole 1021 refers to the diameter of the inscribed circle of the first light-transmitting hole 1021.

[0033] In some embodiments, the first light-transmitting hole 1021 is a through hole provided at the center position or other position of the first connecting member 102. In other embodiments, the first light-transmitting hole 1021 is a blind hole provided at the center position or other position of the first connecting member 102. It is understandable that the blind hole position can be made of a transparent material. Therefore, the first connecting member 102 is made of at least two materials, namely, a transparent material for making the central blind hole area and an opaque material for supporting the shading portion 1020 in the peripheral area. In some other embodiments, the first light-transmitting hole 1021 can be a light-transmitting area flush with the surface of the shading portion 1020, which is not limited here.

[0034] In some other embodiments, the first connecting member 102 further includes a connecting portion, which surrounds the first light-transmitting hole 1021, and the shading portion 1020 surrounds and connects the connecting portion, that is, the shading portion 1020 is a portion of the first connecting member 102 that protrudes from the outer peripheral surface of the imaging module 101 along the radial direction of the imaging module 101.

[0035] The radial direction of the imaging module 101 refers to a direction radiating outward from the center of the imaging module 101 as a circle point.

[0036] Please refer to Figure 3 As shown, Figure 3 : is a front view, a rear view and a cross-sectional view of the first connecting member 102 in an embodiment of the present application, wherein: Figure 3 (a) is the rear view. Figure 3 (b) in Figure 3(c) is a cross-sectional view at 3b-3b, Figure 3 (c) in the figure is a main view. The first connecting member 102 is in the shape of a flat plate, and the first connecting member 102 includes a first surface 1023 and a second surface 1024 arranged opposite to each other, wherein the first surface 1023 is connected to the light-transmitting substrate 200 (i.e., the first light-transmitting substrate 203), and the second surface 1024 is connected to the imaging module 101. The first surface 1023 and the light-transmitting substrate 200 (i.e., the first light-transmitting substrate 203) may be connected by an adhesive layer, or directly by negative pressure adsorption, magnetic adsorption, etc. without an adhesive layer. The second surface 1024 of the first connecting member 102 is connected to the imaging module 101 by, but not limited to, bonding by an adhesive layer, magnetic connection, threaded connection, snap connection, negative pressure adsorption connection, etc., which are not limited here.

[0037] In some embodiments, the ratio of the maximum outer diameter of the first connecting member 102 to the inner diameter of the first light-transmitting hole 1021 ranges from 2:1 to 30:1. When the first connecting member 102 is a non-circular shape, such as a square or polygon, the maximum outer diameter refers to the length of the diagonal of the first connecting member 102. When the first connecting member 102 is circular, the maximum outer diameter refers to the diameter of the first connecting member 102. It should be understood that the maximum outer diameter of the first connecting member 102 does not refer to the maximum achievable outer diameter of the first connecting member 102. Rather, when the first connecting member 102 is in a specific shape, its outer diameter may have multiple values. For example, when the first connecting member 102 is a rectangle with an aspect ratio of 16:9, the outer diameter of the first connecting member 102 varies at different locations, and the maximum outer diameter of the first connecting member 102 refers to the maximum outer diameter among these multiple outer diameter values. The inner diameter of the first light-transmitting hole 1021 refers to the diameter of the first light-transmitting hole 1021. When the first light-transmitting hole 1021 is a non-circular hole, the inner aperture of the first light-transmitting hole 1021 is the diameter of an inscribed circle of the first light-transmitting hole 1021 .

[0038] In some embodiments, the ratio of the inner aperture of the first light-transmitting hole 1021 to the head diameter of the lens of the imaging module 101 is in the range of 1:1 to 3:1. The imaging module 101 includes multiple lenses arranged along its optical axis. The head diameter of the lens of the imaging module 101 refers to the maximum diameter of the lens closest to the incident side of the imaging module 101 among the multiple lenses. The lens closest to the incident side of the imaging module 101 among the multiple lenses is generally also the lens with the largest diameter among the multiple lenses.

[0039] Therefore, by limiting the above ratio range, it can be ensured that when the imaging module 101 is installed on the first connecting member 102, the diameter of the first light-transmitting hole 1021 is large enough so that the imaging module 101 can capture its entire field of view through the first light-transmitting hole 1021 without being blocked by the first connecting member 102, thereby avoiding the imaging of the imaging module 101 from being cropped or distorted.

[0040] In some embodiments, the inner diameter of the first light-transmitting hole 1021 is greater than or equal to the diameter of the maximum area that can be imaged by the imaging module 101 on the surface of the first connecting member 102 facing away from the imaging module 101.

[0041] Thus, when the imaging module 101 is installed on the first connecting member 102, the diameter of the first light-transmitting hole 1021 is large enough so that the imaging module 101 can capture its entire field of view through the first light-transmitting hole 1021 without being blocked by the first connecting member 102, thereby preventing the imaging of the imaging module 101 from being cropped or distorted.

[0042] In some embodiments, as defined above, the shading portion 1020 protrudes from the outer peripheral surface of the imaging module 101 along the radial direction of the imaging module 101. Therefore, the projection ring of the outer peripheral surface of the imaging module 101 on the light-transmitting substrate 200 is located within the projection of the first connecting member 102 on the light-transmitting substrate 200. Therefore, when the imaging module 101 is installed on the light-transmitting substrate 200 through the first connecting member 102, the entire periphery of the first connecting member 102 is exposed from the periphery of the imaging module 101, thereby blocking the light that enters the light-transmitting substrate 200 from the third side 1011 and enters the imaging module 101 after being reflected by the light-transmitting substrate 200.

[0043] It should be noted that the maximum outer diameter of the first connecting member 102 determines the ability of the first connecting member 102 to block light that enters the light-transmitting substrate 200 from the third side 1011 and then enters the imaging module 101 after being reflected by the light-transmitting substrate 200. The larger the maximum outer diameter of the first connecting member 102, the stronger the ability of the first connecting member 102 to block light that enters the light-transmitting substrate 200 from the third side 1011 and then enters the imaging module 101 after being reflected by the light-transmitting substrate 200. Conversely, as the maximum outer diameter of the first connecting member 102 decreases, the ability of the first connecting member 102 to block light that enters the light-transmitting substrate 200 from the third side 1011 and then enters the imaging module 101 after being reflected by the light-transmitting substrate 200 decreases. However, if the maximum outer diameter of the first connecting member 102 is designed to be too large, although it can block all light that enters the light-transmitting substrate 200 from the third side 1011 and enters the imaging module 101 after being reflected by the light-transmitting substrate 200, it will affect the aesthetics and block a large amount of light from the light-transmitting substrate 200, affecting the light-collecting capacity of the light-transmitting substrate 200 itself. Studies have shown that when the first connecting member 102 blocks most of the light that enters the light-transmitting substrate 200 from the third side 1011 and enters the imaging module 101 after being reflected by the light-transmitting substrate 200, even if some light still enters the light-transmitting substrate 200 from the third side 1011 and enters the imaging module 101 after being reflected by the light-transmitting substrate 200, it will not cause glare in the image of the imaging module 101. Therefore, when actually designing the outer diameter of the first connecting member 102 , it is based on being able to block a preset amount of light that enters the transparent substrate 200 from the third side 1011 and enters the imaging module 101 after being reflected by the transparent substrate 200 .

[0044] It should be noted that in actual use, for the sake of aesthetics, the shape of the first connecting member 102 needs to adapt to the shape of the imaging module 101. For example, if the imaging module 101 is square, the first connecting member 102 is an inscribed rectangle in the circle with the maximum outer diameter, which is not limited here.

[0045] In some embodiments, the first connecting member 102 is an inscribed rectangle or inscribed polygon of a circle having the maximum outer diameter as its diameter. It is understood that, depending on the shape of the imaging module 101, the first connecting member 102 can also be an inscribed rectangle or inscribed polygon with other aspect ratios, which is not limited here.

[0046] In some embodiments, please refer to Figure 3 A first protrusion 1022 is provided at the outer edge of the first connecting member 102. The first protrusion 1022 is located at a tangent line of the first connecting member 102.

[0047] Therefore, the first protrusion 1022 can be set as a hand-tear position, and the first connecting member 102 can be conveniently connected between the imaging module 101 and the first light-transmitting substrate 203 through the first protrusion 1022 .

[0048] In some embodiments, the first protrusion 1022 may be, but is not limited to, a rectangular shape, a pointed shape, or other shapes, which are not limited here.

[0049] In some embodiments, when the imaging module 101 has an outer square shape, the first connecting member 102 is an inscribed rectangle of a circle with the maximum outer diameter as the diameter, and the outer edge of the first connecting member 102 has four vertex corners, wherein the first protrusion 1022 is provided at one vertex corner, and the other three vertex corners are chamfered corners.

[0050] Therefore, the processing of the first protrusion 1022 can be facilitated.

[0051] In some specific embodiments, the first connecting member 102 is an inscribed rectangle of a circle having the maximum outer diameter as its diameter. The length and width of the first connecting member 102 are 80±5 mm, respectively. The inner diameter of the first light-transmitting hole 1021 is 32±5 mm. The width of the first protrusion 1022 is 20±5 mm, and the length of the first protrusion 1022 is 8±5 mm. The rounded corners of the first connecting member 102 are 10±5 mm. The thickness of the first connecting member 102 is 1.5±0.5 mm.

[0052] Correspondingly, the length and width of the imaging module 101 are 64±5 mm respectively.

[0053] It is understandable that the above is only an example and can be adjusted as needed in actual applications and is not limited here.

[0054] In some other embodiments, the first connecting member 102 and the imaging module 101 are also connected via a connecting member.

[0055] Specifically, please refer to Figure 5 and Figure 6 The camera assembly 100 also includes a second connecting member 103, wherein the first surface 1023 of the first connecting member 102 is connected to the first light-transmitting substrate 203, and the third surface 1033 of the second connecting member 103 is connected to the imaging module 101, and the first connecting member 102 and the second connecting member 103 have facing surfaces that are detachably connected, that is, the second surface 1024 of the first connecting member 102 and the fourth surface 1034 of the second connecting member 103 are detachably connected.

[0056] Thus, when the first connecting member 102 is connected to the first light-transmitting substrate 203, and the second connecting member 103 is connected to the side of the imaging module 101 facing the first connecting member 102, and the first connecting member 102 and the second connecting member 103 are detachably connected, the relative position relationship between the first connecting member 102 and the second connecting member 103 can be adjusted as needed, and there is no need to adjust the installation position of the first connecting member 102 on the first light-transmitting substrate 203 and the installation position of the second connecting member 103 on the imaging module 101, which is convenient for users to adjust the installation position of the imaging module 101 relative to the first connecting member 102, and facilitates user operation.

[0057] In some embodiments, the first connecting member 102 is a velvet Velcro. Figure 3 As shown, the first surface 1023 is provided with an adhesive layer for connecting with the first light-transmitting substrate 203, and the second surface 1024 is a velvet fabric. The second connecting member 103 is a hook-and-loop velcro. Figure 7 The third surface 1033 is provided with an adhesive layer for connecting to the imaging module 101, and the fourth surface 1034 is provided with a hook surface. Therefore, the second surface 1024 can be detachably connected to the fourth surface 1034. As required, the first connecting member 102 and the second connecting member 103 can be connected to each other or separated from each other.

[0058] In other embodiments, the connection method between the third surface 1033 and the imaging module 101 is not limited to adhesive connection, but can also be magnetic connection, threaded connection, snap connection, negative pressure adsorption connection, etc., which is not limited here.

[0059] For some examples, please refer to Figure 7 , Figure 7 : is a front view, a rear view and a cross-sectional view of the second connecting member 103 in an embodiment of the present application, wherein: Figure 7 (a) is the rear view. Figure 7 (b) in Figure 7 (c) is a cross-sectional view at 7b-7b, Figure 7 (c) is the main view. The second connecting member 103 is flat. A second light-transmitting hole 1031 is provided on the second connecting member 103. The imaging module 101 images the scene on the second side 202 of the light-transmitting substrate 200 through the second light-transmitting hole 1031 and the first light-transmitting hole 1021. The inner aperture of the second connecting member 103 is greater than or equal to the inner aperture of the first light-transmitting hole 1021. During installation, the centers of the first connecting member 102 and the second connecting member 103 coincide within a tolerance range.

[0060] Therefore, the second light-transmitting hole 1031 will not affect the imaging effect of the imaging module 101 .

[0061] In some embodiments, the second light-transmitting hole 1031 is a through hole provided at the center position or other position of the second connecting member 103 .

[0062] In some embodiments, the second light-transmitting hole 1031 is a circular hole. In other embodiments, the second light-transmitting hole 1031 may be a square hole or a polygonal hole, etc., without limitation herein. When the second light-transmitting hole 1031 is a square hole or a polygonal hole, the inner aperture of the second light-transmitting hole 1031 refers to the diameter of the inscribed circle of the second light-transmitting hole 1031.

[0063] In other embodiments, the second light-transmitting hole 1031 is a blind hole disposed at the center or other location of the second connecting member 103. It is understood that the blind hole can be made of a transparent material. In still other embodiments, the second light-transmitting hole 1031 can be a light-transmitting area flush with the third surface 1033 and the fourth surface 1034 of the second connecting member 103, which is not limited here.

[0064] In some embodiments, the ratio of the maximum outer diameter of the second connecting member 103 to the inner diameter of the second light-transmitting hole 1031 ranges from 2:1 to 30:1.

[0065] When the second connecting member 103 is a non-circular shape, such as a square or polygon, the maximum outer diameter refers to the length of the diagonal of the second connecting member 103. When the second connecting member 103 is circular, the maximum outer diameter refers to the diameter of the second connecting member 103. It should be understood that the maximum outer diameter of the second connecting member 103 does not refer to the maximum outer diameter value that the second connecting member 103 can reach. Rather, when the second connecting member 103 is in a specific shape, its outer diameter may have multiple values. For example, when the second connecting member 103 is a rectangle with an aspect ratio of 16:9, the outer diameter of the second connecting member 103 varies at different locations. The maximum outer diameter of the second connecting member 103 refers to the maximum outer diameter among these multiple outer diameter values. The inner diameter of the second light-transmitting hole 1031 refers to the diameter of the second light-transmitting hole 1031. When the second light-transmitting hole 1031 is a non-circular hole, the inner diameter of the second light-transmitting hole 1031 is the diameter of the inscribed circle of the second light-transmitting hole 1031.

[0066] In some embodiments, the ratio of the inner aperture of the second light-transmitting hole 1031 to the head diameter of the lens of the imaging module 101 is in the range of 1:1 to 3:1.

[0067] In which, the imaging module 101 includes multiple lenses arranged along its optical axis direction. The head diameter of the lens of the imaging module 101 refers to the maximum diameter of the lens closest to the incident side of the imaging module 101 among the multiple lenses. The lens closest to the incident side of the imaging module 101 among the multiple lenses is generally also the lens with the largest diameter among the multiple lenses.

[0068] Therefore, by limiting the above ratio range, it can be ensured that the diameter of the second light-transmitting hole 1031 is large enough so that the imaging module 101 can capture its entire field of view through the second light-transmitting hole 1031 without being blocked by the second connecting member 103, thereby avoiding the imaging of the imaging module 101 from being cropped or distorted.

[0069] In some embodiments, the maximum outer diameter of the second connecting member 103 is less than or equal to the maximum outer diameter of the imaging module 101. Specifically, when the imaging module 101 is a non-circular shape such as a square or polygon, the maximum outer diameter refers to the length of the diagonal of the imaging module 101. When the imaging module 101 is a circular shape, the maximum outer diameter refers to the diameter of the imaging module 101. It is understandable that the maximum outer diameter of the imaging module 101 does not refer to the maximum outer diameter value that the imaging module 101 can reach, but when the imaging module 101 is in a specific shape, its outer diameter values may be multiple. For example, when the imaging module 101 is a rectangle with an aspect ratio of 16:9, the outer diameters of the imaging module 101 at different positions are different, and the maximum outer diameter of the imaging module 101 refers to the maximum outer diameter among the multiple outer diameter values.

[0070] Therefore, the maximum outer diameter of the second connecting member 103 is smaller than or equal to the maximum outer diameter of the imaging module 101 , which can improve the aesthetics of the second connecting member 103 .

[0071] The second light-transmitting hole 1031 is a through hole provided at the center of the second connecting member 103 .

[0072] In some embodiments, the second light-transmitting hole 1031 is a circular hole. In other embodiments, the second light-transmitting hole 1031 may be a square hole or a polygonal hole, etc., without limitation herein. When the second light-transmitting hole 1031 is a square hole or a polygonal hole, the inner aperture of the second light-transmitting hole 1031 refers to the diameter of the inscribed circle of the second light-transmitting hole 1031.

[0073] In some embodiments, such as Figure 7 As shown, a second protrusion 1032 is provided at the inner edge or the outer edge of the second connecting member 103 .

[0074] Therefore, the second protrusion 1032 can be set as a hand-tear position, and the second connecting member 103 can be conveniently connected to the side of the imaging module 101 facing the first connecting member 102 through the second protrusion 1032.

[0075] In some embodiments, the second protrusion 1032 is square-shaped. In other embodiments, the second protrusion 1032 is sharp-angled and disposed on the inner edge of the second connecting member 103 .

[0076] In some embodiments, when the second connecting member 103 is square, the length and width of the second connecting member 103 are 55±5 mm, respectively, and the inner diameter of the second light-transmitting hole 1031 is 37±5 mm. The length and width of the second protrusion 1032 are both 5±2 mm. The thickness of the second connecting member 103 is 0.8±0.5 mm.

[0077] It is understandable that the above is only an example and can be adjusted as needed in actual applications and is not limited here.

[0078] In summary, it can be seen that the present application has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0079] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements or improvements made within the ideas and principles of the present application should be included in the scope of protection of the present application.
