[0002] At present, in traditional smart devices such as smart phones, smart computers, smart homes and other camera devices, some space needs to be reserved for camera modules. However, as people pursue the trend of miniaturization and weight reduction of camera equipment, the camera module must also be reduced in size.

[0003] In camera equipment, the lens assembly often needs to be moved for anti-shake because of the need for lens anti-shake. The circuit board needs to connect the lens assembly and the mainboard of the camera equipment to power the lens assembly and transmit the image signal collected by the lens assembly to the camera equipment. Therefore, the circuit board will inevitably affect the movement of the lens assembly and thus affect the anti-shake of the lens assembly. In the existing technology, the circuit board of the camera module usually adopts a flexible circuit board, wherein the flexible circuit board refers to a highly reliable and excellently flexible printed circuit board made of polyimide or polyester film as a substrate. It has the characteristics of high wiring density, light weight, thin thickness and good bendability.

[0004] In order to reduce the influence of the flexible circuit board on the movement of the lens assembly, the latest existing technology has a "J"-shaped or double S-shaped flexible circuit board, which is folded several times continuously to reduce the rigidity of the flexible circuit board, so as to obtain good deformation ability and reduce the influence of the flexible circuit board on the movement of the lens assembly.

[0033] Reference below Figures 1 to 7 To describe the camera module according to the first embodiment of the present invention.

[0034] For example Figures 1 to 7 As shown, the camera module according to the embodiment of the present invention includes a lens assembly 100 and a flexible circuit board 200, wherein the lens assembly 100 is used to capture image information, and the flexible circuit board 200 connects the lens assembly 100 and the main board of the camera device, so that the image signal collected by the lens assembly 100 can be converted into an electrical signal and transmitted to the camera device. The flexible circuit board 200 includes a main body 210, a first connecting part 220 and a second connecting part 230, the first connecting part 220 is connected to the lens assembly 100, and the second connecting part 230 is used to connect to the main board of the camera device; the main body 210 is arranged around the lens assembly 100 along the side of the lens assembly 100.

[0035] By such an arrangement, the flexible circuit board 200 is connected to the lens assembly 100 and the camera device through the first connecting part 220, the second connecting part 230 and the main body 210, so that the image signal collected by the lens assembly 100 is transmitted to the main board of the camera device. At the same time, the main body 210 is arranged around the lens assembly 100 along the side of the lens assembly 100, which can make full use of the space near the lens assembly 100 and is conducive to the miniaturization of the camera module.

[0036] It should be understood that the main body 210 is arranged along the side of the lens assembly 100 around the lens assembly 100, which means that the main body 210 is arranged along the side of the lens assembly 100, and the main body 210 is located along the side of the lens assembly 100, so that the volume and length of the lens assembly 100 can be fully utilized for arrangement, and there is no need to occupy a certain space again, thereby reducing the volume of the camera module. The main body 210 can surround the entire lens assembly 100, for example Figures 4 to 7 As shown in the various embodiments, it can also be set along part of the side of the lens assembly 100, for example Figures 1 to 3 Various embodiments shown. Figures 1 to 3 In each of the embodiments shown, the main body 210 is arranged along the side of the lens assembly 100, and there is a certain distance between the first connection part 220 and the second connection part of the flexible circuit board 200, thereby increasing the flexibility and deformation ability of the flexible circuit board 200, reducing the influence of the flexible circuit board 200 on the movement of the lens assembly 100, and allowing the lens assembly 100 to move easily. It is easy to understand that the main body 210 of the flexible circuit board 200 is arranged around the lens assembly 100 and has a certain length, and the flexible circuit board 200 is only connected to the lens assembly 100 through the first connection part 220, so the flexible circuit board 200 has a certain flexibility and deformation ability, so that it will not affect the movement of the lens assembly 100, so that the lens assembly 100 can move well and achieve an anti-shake effect. At the same time, the volume of the camera module is also reduced, and the flexible circuit board 200 is also conducive to heat dissipation.

[0037] In some specific embodiments of the present invention, the first connecting portion 220 and the second connecting portion 230 are respectively located on two opposite surfaces, two adjacent surfaces, or the same surface of the lens assembly 100 .

[0038] For example Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In each of the illustrated embodiments, the first connecting portion 220 and the second connecting portion 230 are respectively located on two opposite surfaces of the lens assembly 100 .

[0039] In the embodiment shown in the figure, the first connecting portion 220 is connected to the lens assembly 100, and the main body 210 is arranged around the lens assembly 100 along the side of the lens assembly 100, and can be arranged around one side of the lens assembly 100 from the side where the first connecting portion 220 is connected to the lens assembly 100, or around both sides of the lens assembly 100 from the side where the first connecting portion 220 is connected to the lens assembly 100, so as to form a circular frame to set the lens assembly 100 therein. The first connecting portion 220 and the second connecting portion 230 are respectively located on two opposite surfaces of the lens assembly 100, so that the flexible circuit board 200 can make full use of the length of the side of the lens assembly 100 to save space, and at the same time, the first connecting portion 220 and the second connecting portion 230 are respectively located on two opposite surfaces of the lens assembly 100, so that the influence of the flexible circuit board 200 on the movement of the lens assembly 100 can be reduced.

[0040] When the first connection portion 220 and the second connection portion 230 are respectively located on two adjacent surfaces or the same surface of the lens assembly 100, the main body 210 can be arranged with a longer length around the side of the lens assembly 100, and then the second connection portion 230 is connected to the main board of the camera device, which can also reduce the influence of the flexible circuit board 200 on the movement of the lens assembly 100. Figure 1 In the illustrated embodiment, the main body 210 is disposed around the lens assembly 100 so that the first connection portion 220 and the second connection portion 230 are located at the same side of the lens assembly 100. The first connection portion 220 and the second connection portion 230 are located on the same surface, opposite surface, or adjacent surface of the lens assembly 100 so that the connection position of the camera module and the mainboard of the camera device can be more flexible.

[0041] In some specific embodiments of the present invention, the main body 210 is circular in shape and the lens assembly 100 is mounted therein.

[0042] For example Figure 2 , Figure 4 , Figure 5 and Figure 6 In each of the embodiments shown, the main body 210 is in a circular shape and the lens assembly 100 is arranged inside. Through such a configuration, the flexible circuit board 200 can be arranged through each side of the lens assembly 100, making full use of the space on each side of the lens assembly 100, which is beneficial to reducing the volume of the camera module.

[0043] Meanwhile, when the main body 210 is arranged in a circular shape, the first connecting portion 220 and the second connecting portion 230 can be arranged on opposite sides of the lens assembly 100, for example Figure 4 , Figure 5 and Figure 6In each embodiment of the present invention, the first connecting portion 220 and the second connecting portion 230 are located on opposite sides of the lens assembly 100. The first connecting portion 220 and the second connecting portion 230 may also be located on adjacent sides or the same side of the lens assembly 100, for example Figure 2 In the illustrated embodiment, the first connection portion 220 and the second connection portion 230 are located at the same side of the lens assembly 100, but the first connection portion 220 and the second connection portion 230 are not directly connected, so the flexible circuit board 200 still has great flexibility, which can reduce the impact on the movement of the lens assembly 100.

[0044] In some specific embodiments of the present invention, the first connecting portion 220 is connected to the bottom of the side surface of the lens assembly 100 .

[0045] For example Figures 1 to 7 In each of the illustrated embodiments, the first connection portion 220 is connected to the bottom of the side of the lens assembly 100. It is easy to understand that the image sensor of the lens assembly 100 is generally located at the bottom of the lens assembly 100, and the first connection portion 220 is connected to the bottom of the side of the lens assembly 100, which is beneficial for the flexible circuit board 200 to receive the image signal transmitted by the lens assembly 100.

[0046] In some specific embodiments of the present invention, the flexible circuit board 200 also includes a first bending portion 240, which is connected to the first connecting portion 220 and bent toward the top of the lens assembly 100, and the two ends of the first bending portion 240 are respectively connected to the first connecting portion 220 and the main body 210.

[0047] For example Figure 5 and Figure 6 As shown, the flexible circuit board 200 also includes a first bending portion 240, which is connected to the first connecting portion 220 and is bent toward the top of the lens assembly 100 to be connected to the main body 210, and the main body 210 is connected to the first connecting portion 220 through the first bending portion 240.

[0048] By such arrangement, the plane where the main body 210 is located can be moved upward, thereby saving space at the bottom of the lens assembly 100. By setting the first bending portion 240, the flexible circuit board 200 can be more flexibly arranged around the side of the lens assembly 100, and the main body 210 of the flexible circuit board 200 can be selected to be located at the bottom, middle or other position of the lens assembly 100. The flexible arrangement can free up space for other devices such as a driving device, so that the camera module can better utilize space.

[0049] In some specific embodiments of the present invention, the flexible circuit board 200 also includes a second bending portion 250, which is connected to the main body 210 and is bent toward the bottom or top of the lens assembly 100 to connect to the second connecting portion 230, and the two ends of the second bending portion 250 are respectively connected to the second connecting portion 230 and the main body 210.

[0050] For example Figure 6 In the illustrated embodiment, the second bending portion 250 is connected to the main body 210 and is connected to the second connecting portion 230 after being bent toward the bottom of the lens assembly 100. The main body 210 is connected to the second connecting portion 230 via the second bending portion 250. By such an arrangement, the connection position between the flexible circuit board 200 and the main board can be more flexible, and the position of connection with the main board can be flexibly selected as needed, which is more convenient and conducive to the effective use of space by the camera module.

[0051] In some specific embodiments of the present invention, there is a certain distance between the main body 210 and the side surface of the lens assembly 100 .

[0052] For example Figures 1 to 6 In the various embodiments shown, the main body 210 is disposed around the side of the lens assembly 100 and has a certain distance from the side of the lens assembly 100, leaving some space for the lens assembly 100 to facilitate the movement of the lens assembly 100.

[0053] In some specific embodiments of the present invention, the plane where the main body 210 is located is perpendicular to the optical axis S of the lens assembly 100 .

[0054] For example Figures 1 to 6 In each of the illustrated embodiments, the plane where the main body 210 is located is perpendicular to the optical axis S direction of the lens assembly 100. This arrangement is more conducive to the movement of the lens assembly 100.

[0055] In some specific embodiments of the present invention, the flexible circuit board 200 is integrally formed.

[0056] The flexible circuit board 200 is formed in one piece, which is convenient for manufacturing. The technical features such as the main body 210, the first connecting portion 220, the second connecting portion 230, the first bending portion 240 and the second bending portion 250 are only for the convenience of description, and do not mean that the flexible circuit board 200 must be composed of multiple circuit boards.

[0057] According to an embodiment of the second aspect of the present invention, a camera device includes the camera module of the embodiment of the first aspect mentioned above.

[0058] The camera device according to the second embodiment of the present invention is configured in this way, which is conducive to miniaturization of the camera device, and the lens assembly 100 can be moved more easily and is conducive to heat dissipation of the flexible circuit board 200.
