Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, specifically to a high-gloss eyeglass frame with a large radius structure. Background Technology

[0002] In the manufacturing process of high-gloss products, the frame is a crucial component, and its appearance quality is always a key concern for customers. Currently, high-gloss product frames on the market often exhibit light reflection distortion at the edges under illumination, which severely affects the product's appearance quality and fails to meet customer needs.

[0003] Research revealed that the problem is primarily caused by two factors: product structure and manufacturing process. Structurally, existing frames feature a flanged edge, with the flange thickness exceeding the main frame thickness, typically by more than 2mm. Additionally, the product's radius (R) is only 1.5mm. This R-angle design fails to completely conceal the flange, making the flange reduction quite noticeable on the surface, resulting in light distortion under certain lighting conditions.

[0004] In terms of processing technology, when the product's radius (R) is 1.5mm, a φ2 tool is required for machining. However, to ensure processing efficiency, a slightly larger tool is needed for machining the larger outer surfaces. Since tool marks are created at the junctions of different tools, this can distort the light reflected from the product, further affecting its appearance quality.

[0005] To solve the above problems, the commonly used method is to reduce the thickness of the flange wall to less than 1.5mm. However, this method will affect the strength of the product, and customers rarely agree to the change. Therefore, it is necessary to design a high-gloss product frame with a large radius structure. Utility Model Content

[0006] The purpose of this invention is to provide a high-gloss product frame with a large radius structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-gloss product frame with a large radius angle structure, comprising a frame body, wherein the edge of the frame body is provided with a flange structure, the radius angle of the frame body is R2.5mm, and the wall thickness of the flange structure is less than or equal to 1.5mm; the high-gloss surface of the frame body is machined into a continuous smooth curved surface using a φ4 cutting tool, and the connection between the high-gloss surface and the flange structure is transitioned through the radius angle.

[0008] Preferably, the flange structure is arranged circumferentially along the edge of the frame body, and a stepped transition structure is formed between the inner wall of the flange structure and the inner wall of the frame body, wherein the step height of the stepped transition structure is 0.8-1.2mm.

[0009] Preferably, a reinforcing rib is provided at the connection between the flange structure and the main wall of the frame body, and the height of the reinforcing rib is 1.5-2 times the wall thickness of the flange structure.

[0010] Preferably, the high-gloss surface of the frame body is provided with an anti-glare pattern, which is a microprism array evenly distributed along the circumferential radius of the outer surface R-angle, and the height of the microprism is 5-10μm, and the spacing between adjacent microprisms is 20-30μm.

[0011] Preferably, the inner wall of the frame body is provided with a snap-fit ​​groove, the groove having a depth of 2-3 mm and a width of 1.5-2 mm.

[0012] Preferably, the curved surface profile of the outer R-angle is formed by NURBS curve fitting, and the curved surface of the outer R-angle, the high-gloss surface, and the outer wall of the flange structure all adopt a continuous G2 transition.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By increasing the R-angle of the appearance to R2.5mm, this utility model can completely cover the shrinkage of the flange structure, effectively improve the problem of light reflection distortion at the edge position under light illumination, and improve the appearance quality of the product.

[0015] (2) This utility model uses a φ4 tool to process the high-gloss surface as a whole, avoiding the generation of tool marks, making the high-gloss surface smoother and flatter, and improving the processing quality of the product.

[0016] (3) This utility model combines a large R-angle design, and the anti-glare structure can further improve the light reflection disorder caused by the shrinkage of the original flange. The traditional R1.5mm frame is prone to light distortion under light due to the shrinkage of the flange and the tool marks, while the micro prism array can weaken such distortion by scattering light, making the light reflection on the appearance surface more uniform.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a high-gloss product eyeglass frame with a large radius angle structure, including an eyeglass frame body 1, an edge flange structure 2 provided at the edge of the eyeglass frame body 1, the outer radius angle 3 of the eyeglass frame body 1 is R2.5mm, and the wall thickness of the edge flange structure 2 is less than or equal to 1.5mm; the high-gloss outer surface 4 of the eyeglass frame body 1 is machined into a continuous smooth curved surface using a φ4 cutting tool, and the connection between the high-gloss outer surface 4 and the edge flange structure 2 is transitionally connected through the outer radius angle 3.

[0023] In this invention, the flange structure 2 is arranged circumferentially along the edge of the frame body 1, and a stepped transition structure is formed between the inner wall of the flange structure 2 and the inner wall of the frame body 1, wherein the step height of the stepped transition structure is 0.8-1.2mm.

[0024] In this invention, a reinforcing rib is provided at the connection between the flange structure 2 and the main wall of the frame body 1, and the height of the reinforcing rib is 1.5-2 times the wall thickness of the flange structure.

[0025] In this invention, an anti-glare pattern 5 is provided on the high-gloss surface of the frame body 1. The anti-glare pattern 5 is an array of microprisms evenly distributed circumferentially along the radius (R) of the outer surface, with the height of each microprism being 5-10 μm and the spacing between adjacent microprisms being 20-30 μm. This invention, combined with a large radius (R) design, allows the anti-glare pattern structure to further improve the light reflection disorder caused by the shrinkage of the original flange. Traditional 1.5mm frames are prone to light distortion under lighting due to flange shrinkage and joinery marks, while the microprism array, by scattering light, can weaken this distortion phenomenon, resulting in more uniform light reflection on the outer surface.

[0026] In this utility model, the inner sidewall of the frame body 1 is provided with a snap-fit ​​groove 6, the groove depth of which is 2-3mm and the groove width is 1.5-2mm.

[0027] In this invention, the curved surface profile of the outer R-angle is formed by NURBS curve fitting, and the curved surface of the outer R-angle, the high-gloss surface, and the outer wall of the flange structure all adopt a continuous G2 transition.

[0028] Example: High-gloss lens frames for consumer electronics

[0029] Structural parameters: The main body of the frame is made of aluminum alloy, with a flange structure wall thickness of 1.2mm, distributed circumferentially along the edge; the exterior R-angle design is R2.5mm, and the surface is fitted by NURBS curve to achieve a continuous G2 transition with the high-gloss surface.

[0030] Anti-glare structure: On the high-gloss surface, the mold surface is processed by electrical discharge machining to form a micro-prism array with a height of 8μm and a spacing of 25μm, which is uniformly distributed along the circumferential direction of the R-angle.

[0031] Machining process: High-gloss surface is CNC milled using φ4 carbide tools to ensure no tool marks on the entire curved surface; the gradually tapering wall thickness and reinforcing rib structure of the flange structure are directly formed during mold injection, with a reinforcing rib height of 1.8mm.

[0032] Test results: In the light room test, the light reflection distortion phenomenon disappeared, the mirror reflection light intensity decreased by 40%, and the glare value met the ISO 16505 anti-glare standard; after the drop test, the flanged structure did not crack, and the strength met the requirements of consumer electronic devices.

[0033] In summary, by increasing the outer radius (R) to R2.5mm, this invention can completely cover the shrinkage of the flanged structure, effectively improving the problem of light reflection and distortion at the edge under illumination, and enhancing the product's appearance quality. Furthermore, this invention uses a φ4 cutting tool to process the high-gloss surface as a whole, avoiding tool marks and resulting in a smoother and flatter surface, thus improving the product's processing quality.
