[0038] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] It should be noted that the first direction X, second direction Y, and optical axis direction Z indicated in the application documents are merely for the purpose of providing a detailed description of the camera module provided in this application in conjunction with the accompanying drawings, and this application is not limited thereto. The optical axis direction Z is defined by the lens, the plane defined by the first direction X and the second direction Y is perpendicular to the optical axis direction Z, and the first direction X and the second direction Y are mutually perpendicular.

[0040] like Figure 1 and Figure 2 As shown, the camera module provided by the present application includes a lens, a drive assembly 1, and a photosensitive assembly. The lens is connected to the drive assembly 1, and the photosensitive assembly is spaced apart on the side of the drive assembly 1 away from the lens. The drive assembly 1 can drive the lens to move along its optical axis direction Z to adjust the focal length, and can also drive the lens to move in a plane perpendicular to the optical axis direction Z to achieve lens anti-shake.

[0041] The drive assembly 1 includes at least two moving components 11, and the two adjacent moving components 11 are slidingly connected by a rolling structure 12; through the relative movement between the moving components 11 along the optical axis direction Z, the lens can be driven to move back and forth along the optical axis direction Z to achieve focal length adjustment; through the relative movement between the moving components 11 along the first direction X and the second direction Y, the lens can be moved in a plane perpendicular to the optical axis direction Z, achieving the effect of lens anti-shake.

[0042] The rolling structure 12 includes two guide grooves 121 and balls 122. The two guide grooves 121 extend in the same direction, and the groove openings of the two guide grooves 121 are arranged opposite to each other; one of the guide grooves 121 is arranged in one movable member 11, and the other guide groove 121 is arranged in another adjacent movable member 11. The ball 122 is arranged between the two guide grooves 121. The radius of the ball 122 is greater than the depth of the guide groove 121. When the ball 122 contacts the bottom of the two guide grooves 121, there is a gap between the two movable members 11 to prevent the two movable members 11 from contacting each other and causing friction during the relative movement, thereby avoiding affecting the smoothness of the relative movement of the two movable members 11 and generating noise.

[0043] The space between the two guide grooves 121 is filled with lubricating oil, which can cover the balls 122 to further reduce the friction force applied to the balls 122 when rolling in the guide grooves 121 .

[0044] An oleophobic layer 13 is provided on the inner surface of the two guide grooves 121. By providing the oleophobic layer 13, the lubricating oil is not easily attached to the inner surface of the guide groove 121, thereby reducing the situation where the lubricating oil adheres to the inner surface of the guide groove 121 and sticks the ball 122 to the guide groove 121, affecting the rolling of the ball 122. It can effectively ensure the smooth and continuous rolling of the ball 122, and can ensure the smooth movement of the lens when driving the lens to move, reduce the situation of shooting picture jamming, and ensure the shooting quality.

[0045] Alternatively, as Figure 1 and Figure 2 As shown, an angle of approximately 60° is formed between the bottom of the guide groove 121 and the two side groove walls parallel to its extension direction. After the two guide grooves 121 are matched, a channel roughly in the shape of a regular hexagon can be formed. When the ball 122 rolls in it, the ball 122 can roughly evenly contact the bottom and groove wall of the guide groove 121, which can reduce the situation where the ball 122 shakes evenly in the two guide grooves 121 and generates noise.

[0046] like Figure 2 and Figure 3 As shown, the camera module provided by the present application, wherein the oleophobic layer 13 is formed by a plurality of oleophobic protrusions 131 arranged in an array, and the end of the oleophobic protrusion 131 away from the inner surface of the guide groove 121 has a raised arc-shaped end face, and the lubricating oil is not easy to adhere to the highest position of the protrusion at the farthest position from the inner surface of the guide groove 121 on the arc-shaped end face, and the arc-shaped end face is in contact with the ball 122 at the highest position of the protrusion, thereby effectively preventing the ball 122 from being stuck to the inner surface of the guide groove 121 by the lubricating oil.

[0047] like Figure 3 As shown, the camera module provided by the present application, wherein the oleophobic protrusion 131 includes a connecting portion 1311 and an oleophobic portion 1312. The oleophobic portion 1312 is spherical, one end of the connecting portion 1311 is connected to the oleophobic portion 1312, and the other end of the connecting portion 1311 is connected to the inner surface of the guide groove 121. The connecting portion 1311 is generally cylindrical in structure, and the radial dimension of the connecting portion 1311 is smaller than the diameter D of the oleophobic portion 1312, so that the connecting portion 1311 only serves as a connection.

[0048] The connection between the oleophobic portion 1312 and the connecting portion 1311 defines a connecting surface 1313. The angle α formed between the tangent line L at the connecting position between the oleophobic portion 1312 and the corresponding connecting portion 1311 and the connecting surface 1313 is greater than or equal to a preset angle. That is, the surface of the oleophobic portion 1312 protrudes from the peripheral side surface of the connecting portion 1311. Figure 4 and Figure 5 As shown, since the lubricating oil is a liquid and the liquid has a certain tension, the smaller the angle α between the tangent line L at the connection position between the oleophobic portion 1312 and the corresponding connecting portion 1311 and the connecting surface 1313, the easier it is for the lubricating oil to diffuse and adhere to the surface of the oleophobic portion 1312 protruding from the connecting surface 1313 under the action of tension. The larger the angle α between the tangent line L at the connection position between the oleophobic portion 1312 and the corresponding connecting portion 1311 and the connecting surface 1313, the less likely the lubricating oil is to diffuse and adhere to the surface of the oleophobic portion 1312 protruding from the connecting surface 1313. Therefore, the preset angle is limited to 150°, that is, the angle α formed between the tangent line L at the connection position between the oleophobic portion 1312 and the corresponding connecting portion 1311 and the connecting surface 1313 is greater than or equal to 150°, which can effectively achieve a super oleophobic effect.

[0049] like Figure 3 As shown, in the camera module provided by the present application, the oleophobic portions 1312 of every two adjacent oleophobic protrusions 131 are in contact, so that the oleophobic protrusions 131 are closely arranged to form a continuous and complete oleophobic layer 13.

[0050] The camera module provided herein has a micron-scale structure, wherein the oleophobic protrusions 131 have a smooth appearance and excellent oleophobic effect. The distance between the central axes of two adjacent oleophobic portions 1312 is equal to the diameter D of the oleophobic portion 1312. The micron-scale oleophobic protrusions 131, combined with the specific structure of the oleophobic protrusions 131, can effectively ensure a super-oleophobic effect. Specifically, the radius of the oleophobic portion 1312 is approximately 5μm to 10μm, and the distance between the central axes of two adjacent oleophobic portions 1312, as well as the diameter D of the oleophobic portion 1312, is twice the radius of the oleophobic portion 1312.

[0051] Optionally, the oleophobic layer 13 can be embedded in the guide groove 121 in the form of an insert during the process of forming the guide groove 121 on the moving member 11 .

[0056] Through the rolling structure 12 between the first moving seat 112 and the second moving seat 113, the first moving seat 112 and the second moving seat 113 can be guided to move along the first direction X, and the friction generated when the first moving seat 112 and the second moving seat 113 move relative to each other can be reduced; through the rolling structure 12 between the second moving seat 113 and the third moving seat 114, the second moving seat 113 and the third moving seat 114 can be guided to move along the second direction Y, and the friction generated when the second moving seat 113 and the third moving seat 114 move relative to each other can be reduced; through the rolling structure 12 between the third moving seat 114 and the sleeve 111, the third moving seat 114 and the sleeve 111 can be guided to move along the optical axis direction Z, and the friction generated when the third moving seat 114 and the sleeve 111 move relative to each other can be reduced.
