The first decorative piece 100 includes a first decorative body 110 and a first identification body 120 provided on the first decorative body 110; the second decorative piece 200 includes a second decorative body 210 and a second identification body 220. The second decorative body 210 is provided on the outside of the first decorative body 110, and the first identification body 120 is exposed on the outside of the second decorative body 210 in a preset identification area. The second identification body 220 is provided in the preset identification area and cooperates with the first identification body 120 to form a preset identification pattern.
[0025] In the technical solution of the present invention, the first decorative piece 100 and the second decorative piece 200 are double-color injection molded. The first decorative piece 100 includes a first decorative body 110 and a first identification body 120. The first identification body 120 is protruding on one side of the first decorative body 110, and the second decorative body 210 is arranged on the side of the first decorative body 110 where the first identification body 120 is arranged. In a preset area position, the first identification body 120 and the second identification body 220 cooperate to form a preset identification pattern, and are exposed on the outside of the second decorative body 210. Since the first decorative piece 100 and the second decorative piece 200 are double-color injection molded, that is, the first decorative piece 100 and the second decorative piece 200 are made of materials of different colors, that is, the first identification body 120 and the second decorative piece 200 are different in color, which solves the problem of similar colors and unclear logos. In addition, the use of injection molding process for one-piece molding also solves the problem of insufficient fit, improves the aesthetics of the logo, and makes the preset logo pattern more obvious on the product shell.
[0026] Among them, the first decorative piece 100 includes a first decorative body 110 and a first logo body 120, and the second decorative piece 200 includes a second decorative body 210 and a second logo body 220. This solution is formed by injection molding using a first mold and a second mold. The first logo body 120 is formed by injection molding the first decorative piece 100 in a single injection molding process, and the first mold and the first decorative piece 100 are used as a rear mold for secondary injection molding, and the second mold is used as a front mold to cooperate with injection molding to form the second decorative piece 200. The second decorative body 210 is set at On the first decorative body 110, and the two use injection molding materials of different colors, the first identification body 120 and the second identification body 220 cooperate to form a preset identification pattern so that the preset identification pattern is clearer and more visible; the first mold is processed at the position corresponding to the first identification body 120 of the first mold, such as mirror electric spark processing, so that the surface roughness Ra is less than 0.2μm, or the position of the first mold corresponding to the first identification body 120 is textured, so that the surface brightness of the first identification body 120 after one-shot injection molding is smoother and the appearance is also higher.
[0027] Typically, the first decorative piece 100 and the second decorative piece 200 are made of hard plastic, and the melting point of the material of the first decorative piece 100 is higher than that of the material of the second decorative piece 200. This can prevent the material of the first decorative piece 100 from melting due to excessively high temperature during the second injection, causing the two materials to mix and affect the color contrast. Selecting a material with a high melting point for the first shot and a material with a low melting point for the second shot can ensure clear color boundaries and enhance the visual effect.
[0028] In the embodiment of the present invention, the second decoration body 210 is provided with a through hole 211 in the predetermined logo area, and the first logo body 120 is exposed at the through hole 211 .
[0029] Specifically, please refer to Figure 5 The shape of the through hole 211 is the same as that of the first identification body 120, so that when the second decorative body 210 is installed on the side of the first decorative body 110 where the first identification body 120 is provided, the first identification body 120 is just exposed to the outside in the through hole 211. Since the colors of the first identification body 120 and the second decorative part 200 are different, the preset identification pattern is also clearer.
[0030] by Figure 1Taking the embodiment as an example, the preset identification pattern in this embodiment is a "B" type pattern, that is, the shape of the through hole 211 is the outer peripheral shape of the "B" type pattern, and the pattern of the first identification body 120 is "B" type. Since the "B" type pattern is a closed shape, two through holes 121 are provided in the middle of the first identification body 120, and the second identification body 220 is provided in the through hole 121 and cooperates with the second decorative body 210, so that the first identification body 120 is more clearly exposed at the through hole 211; in other embodiments, the preset identification pattern is an open shape, such as a "C" type structure, then the shape of the through hole 211 is "C" shape, and the second identification body 220 is in the arc circle of the "C" type structure, and cooperates with the second decorative body 210 and the first identification body 120, so that the preset identification pattern is clearly visible at the through hole 211.
[0031] In an embodiment of the present invention, the through hole 211 includes a first hole position and a second hole position, the first hole position is close to the inner side of the second decorative body 210, and the second hole position is close to the outer side of the second decorative body 210, and the aperture of the first hole position is larger than the aperture of the second hole position, so that when the first identification body 120 is set in the first hole position, the surface of the second hole position is higher than the first identification body 120 and covers the outer edge of the first identification body 120.
[0032] Please refer to Figure 3 The through hole 211 includes a first hole position and a second hole position with different hole diameters. The hole diameter of the first hole position is larger than the hole diameter of the second hole position, and the first hole position is close to the first decorative body 110, and the second hole position is far away from the first decorative body 110. The first logo body 120 is located at the first hole position, that is, it can be understood that the second hole position is higher than the first logo body 120, so that the first logo body 120 is recessed relative to the second decorative part 200, and the first logo body 120 is in contact with the inner wall of the first hole position, that is, the inner wall of the second hole position will cover the edge of the first logo body 120, which can make the transition between the first logo body 120 and the second decorative part 200 smoother and more natural, avoiding obvious dividing lines or gaps, thereby improving the aesthetics of the preset logo pattern. In addition, if the first logo body 120 and the second decorative part 200 are directly adjacent, they may separate after long-term use due to reasons such as different thermal expansion coefficients. If the second decorative part 200 covers the edge of the first logo body 120, this risk can be reduced and reliability for long-term use can be ensured.
[0033] In the embodiment of the present invention, the second logo body 220 is higher than the first logo body 120 and covers the inner edge of the first logo body 120 .
[0034] Please refer to Figure 3The second identification body 220 is the same as the inner wall of the second hole, is higher than the inner side of the first identification body 120, and covers the inner edge of the first identification body 120, so that the color transition between the second identification body 220 and the first identification body 120 is more natural, avoiding the appearance of obvious dividing lines or gaps that affect the aesthetics, and can also avoid separation due to different thermal expansion coefficients after long-term use, thereby ensuring reliability for long-term use.
[0035] In an embodiment of the present invention, the width of the side wall of the second hole covering the outer edge of the first identification body 120 is greater than or equal to 0.2 mm; in another embodiment, the width of the second identification body 220 covering the inner edge of the first identification body 120 is greater than or equal to 0.2 mm. It should be noted that a sealing surface is provided at the connection between the inner edge of the first identification body 120 and the second identification body 220 and the outer edge and the inner wall of the second hole to provide an additional sealing layer to prevent moisture, dust, etc. from entering the interior. In addition, it can also increase the mechanical bonding force between the first decorative part 100 and the second decorative part 200, reduce the risk of separation, make the transition smooth and natural, reduce the visibility of the boundary line, and enhance the overall aesthetics of the preset identification pattern.
[0036] In an embodiment of the present invention, a sealing groove 300 is provided at the edge connection between the first decorative piece 100 and the second decorative piece 200, so that the material of the second decorative piece 200 can be better embedded in the first decorative piece 100 during injection, making the combination more stable, and can also eliminate the tiny gap between the first decorative piece 100 and the second decorative piece 200, thereby improving the sealing effect and preventing moisture or other contaminants from passing through.
[0037] In one embodiment, the width of the sealing groove 300 is at least 0.4 mm. In another embodiment, the height of the sealing groove 300 is at least 0.2 mm, providing sufficient space for the first decorative piece 100 to be combined with the second decorative piece 200 .
[0038] In the embodiment of the present invention, a glue hole 111 is provided on a side of the first decorative body 110 where the first logo body 120 is provided, away from the first logo body 120 .
[0039] Please refer to Figure 3 and Figure 6Since the first identification body 120 is protrudingly arranged on one side of the first decorative body 110, the position of the first decorative body 110 where the first identification body 120 is arranged is thicker. By setting the glue hole 111 on the inner side of the first decorative body 110, that is, on the side away from the first identification body 120, the overall thickness of the first decorative part 100 is made consistent, avoiding the different cooling speeds of the first decorative part 100, thereby affecting the injection of the second decorative part 200, reducing the internal stress caused by the different cooling speeds, and reducing the risk of shell deformation.
[0040] In an embodiment of the present invention, the edge of the glue hole 111 is provided with a rounded corner. Since the glue hole 111 can be used as the position of the ejector pin of the first mold, the setting of the rounded corner makes it easier for the first decorative part 100 to be demolded in the first mold, reduces the demolding resistance, and prevents the first decorative part 100 from being damaged.
