[0002] In vehicles, bright trim strips are often used to improve the aesthetics and high-end feel of the product. However, the bright trim strips in the related art are easy to damage and expensive because they require special processing and manufacturing processes during molding. In addition, although black bright trim strips are gradually accepted by the market, their surface is prone to light distortion. Therefore, the bright trim strips in the related art are easy to damage, affecting the overall aesthetics of the vehicle. Summary of the invention

[0004] The edging assembly provided in the first aspect of the present application is composed of a decorative layer and an edging piece. Among them, the decorative layer is obtained by an injection molding process of a polyurethane injection molding material. The polyurethane injection molding material has a sufficiently low viscosity and high fluidity, so the injection molding pressure is small, and it can be applied to the surface of the edging piece as a surface coating. The surface of the decorative layer thus obtained can present a typical high gloss, gorgeous 3-D depth and luxurious appearance effect. The surface of the decorative layer itself is smooth and bright, and the surface visual effect is more beautiful, which improves the aesthetics of the vehicle and meets consumers' pursuit of high-quality and perfect appearance.

DETAILED DESCRIPTION

[0053] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.

[0054] Unless otherwise specified or there is a contradiction, the terms and phrases used in this application have the following meanings:

[0055] In this application, "first", "second", etc. are used only for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0056] In this application, "one or several" refers to any one, any two or more of the listed items. Among them, "several" refers to any two or more of the listed items.

[0057] In the present application, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0058] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be connected, detachably connected, or integrated. It can be mechanically connected or electrically connected. It can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0059] In the related art, it is difficult to achieve a high black and glossy effect on the appearance of the edging piece without bright trim strips. If bright trim strips are used, it is difficult to achieve diversification of the appearance due to its molding process. In addition, the molding process of the bright trim strips limits the dimensional accuracy of the product. It is easy to produce flash when it is integrally injected with the edging piece, and it is easy to scratch the appearance of the bright trim strip during later trimming. In addition, if the edging piece is too thick, it will easily shrink and deform, and then pull the surface of the bright trim strip, causing the bright trim strip to produce light distortion, affecting the aesthetics of the product. Therefore, the present application uses a decorative layer to replace the bright trim strip in the related art, which can not only improve the aesthetics of the product, but also achieve diversification and reduce costs.

[0061] The present embodiment provides an edging component 1, which is applied to a vehicle, wherein the vehicle includes a vehicle window glass 2, and the edging component 1 includes an edging piece 11 and a decorative layer 12 arranged on one side of the edging piece 11, wherein the edging piece 11 is used to wrap the vehicle window glass 2, and the decorative layer 12 is used to decorate the vehicle, and the decorative layer 12 is obtained by an injection molding process using a polyurethane injection molding material.

[0062] The edging component 1 provided in this embodiment includes an edging piece 11 for wrapping the vehicle window glass 2. The material of the edging piece 11 includes at least one of PU, PVC, and TPE. The edging piece 11 is obtained by injection molding. The shape of the edging piece 11 is adapted to the shape of the vehicle window glass 2. The vehicle window glass 2 can be a front windshield, or a side window glass, or a corner window glass, or a rear windshield, or a sunroof glass, etc. Optionally, the edging piece 11 includes a first edging portion 111, and a second edging portion 112 connected to the first edging portion 111, and the first edging portion 111 is used to wrap the vehicle window glass 2. Optionally, the second edging portion 112 is used to overlap the body matching parts of the vehicle.

[0063] The hardness of the edging member 11 is less than the hardness of the decorative layer 12. Optionally, the hardness of the edging member 11 is 50A-95A. Optionally, the Shore hardness of the decorative layer 12 is 80D-60A. For example, the Shore hardness of the decorative layer 12 can be 80D, or 100D, or 20A, or 30A, or 40A, or 50A, or 60A, etc.

[0064] The edging assembly 1 provided in this embodiment also includes a decorative layer 12 for decorating a vehicle. The decorative layer 12 is obtained by an injection molding process of a polyurethane injection molding material. Optionally, the polyurethane injection molding material includes at least one of polyurethane (PUR) and polyurea (PUA). Optionally, the polyurethane injection molding material is liquid. The decorative layer 12 allows light to pass through; or the decorative layer 12 has a specific color that prevents light from passing through. The decorative layer 12 can be arranged on the outside of the vehicle as an exterior decoration of the vehicle. The decorative layer 12 can also be arranged on the inside of the vehicle as an interior decoration of the vehicle.

[0065] In one embodiment, if Figure 5 As shown, along the stacking direction from the edging piece 11 to the decorative layer 12 , the thickness T of the decorative layer 12 satisfies the following condition: 0.2 mm≤T≤2 mm.

[0066] For example, the thickness T of the decoration layer 12 may be 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, or 2 mm, etc. In this embodiment, by limiting the thickness of the decoration layer 12 to 0.2 mm-2 mm, the decoration layer 12 can have a thinner high-gloss surface and reduce production costs.

[0067] The polyurethane injection molding material has sufficiently low viscosity and high fluidity, so the injection molding pressure is small, and it can be applied as a surface coating to the surface of the edging piece 11. The surface of the decorative layer 12 obtained in this way can present a typical high gloss and gorgeous 3-D depth and luxurious appearance. The surface of the decorative layer 12 itself is smooth and bright, and the surface visual effect is more beautiful, which improves the beauty of the vehicle and meets consumers' pursuit of high-quality and perfect appearance. In addition, the decorative layer 12 does not require additional polishing, which reduces production costs and improves production efficiency.

[0068] In addition, polyurethane has self-healing properties. If the decorative layer 12 is scratched due to careless use, the self-healing effect of polyurethane can provide additional protection for the surface of the decorative layer 12, so that the surface of the decorative layer 12 always maintains a perfect appearance and greatly improves the scratch resistance.

[0069] In addition, the polyurethane material has a high hardness and can act as a plastic skeleton to increase the dimensional stability of the edging component 1; it can not only prevent the product edging piece 11 from collapsing when pressed, but also prevent problems such as optical distortion of the outer surface of the decorative layer 12 after rebounding after being pressed.

[0070] Therefore, the present embodiment provides a decorative layer 12 made of polyurethane injection molding material through an injection molding process on the edging member 11, which is convenient for processing and production, and does not require the use of bright decorative strips in the related art, thereby reducing production costs and improving product aesthetics. In addition, the decorative layer 12 has a strong hardness, which can overcome the shrinkage problem caused by the edging member 11, enhance the dimensional stability of the edging component 1, effectively avoid the problem of light distortion on the surface of the black bright decorative strip, and effectively improve the durability of the edging component 1.

[0071] Please refer to Figure 3-Figure 8 In one embodiment, the edging member 11 includes a first edging portion 111 and a second edging portion 112 connected to the first edging portion 111, the first edging portion 111 is used to wrap the vehicle window glass 2, the second edging portion 112 is farther away from the vehicle window glass 2 than the first edging portion 111, the decorative layer 12 is arranged on one side of the second edging portion 112, and the second edging portion 112 is provided with at least one groove 1121, and the groove 1121 is used to accommodate part of the decorative layer 12.

[0072] The edging member 11 includes a first edging portion 111 and a second edging portion 112. The shape of the first edging portion 111 is adapted to the shape of the vehicle window glass 2. Optionally, the first edging portion 111 is bent and connected to the second edging portion 112. The decorative layer 12 is arranged on the surface of the second edging portion 112 and is also arranged in the groove 1121. The number of the grooves 1121 is one or more.

[0073] Due to the incompatibility between the material of the edging piece 11 and the material of the decorative layer 12, the connection performance between the edging piece 11 and the decorative layer 12 is poor. In this embodiment, by providing a groove 1121 in the second edging portion 112 of the edging piece 11, during the injection molding process, the liquid polyurethane injection molding material can flow into the groove 1121 to fill the groove 1121. After the liquid polyurethane injection molding material is hardened, the part of the decorative layer 12 provided in the groove 1121 can provide a fixing mechanical claw force, so that the decorative layer 12 is firmly fixed on the edging piece 11, thereby improving the connection performance between the edging piece 11 and the decorative layer 12.

[0074] In one embodiment, if Figure 6 As shown, the depth H1 of the groove 1121 satisfies the following condition: 0.5 mm ≤ H1 ≤ 3 mm; and / or the opening width H2 of the groove 1121 satisfies the following condition: 0.5 mm ≤ H2 ≤ 3 mm.

[0075] For example, the depth H1 of the groove 1121 may be 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3 mm, etc. For another example, the opening width H2 of the groove 1121 may be 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3 mm, etc.

[0076] This embodiment limits the depth of the groove 1121 to 0.5mm-3mm and the opening width of the groove 1121 to 0.5mm-3mm, which not only facilitates the polyurethane injection molding material to flow into the groove 1121, but also reduces the overall thickness of the decorative layer 12, thereby improving the aesthetics of the decorative layer 12 and improving the product texture of the decorative layer 12.

[0077] Please refer to Figure 3-Figure 8 In one embodiment, the decorative layer 12 includes a first end 121 and a second end 122 that are arranged opposite to each other, the second end 122 is farther away from the first edging portion 111 than the first end 121, and the second edging portion 112 is provided with a first groove 1121a, and the first groove 1121a is used to accommodate the first end 121.

The groove 1121 includes a first groove 1121a, and the first groove 1121a is provided at a portion of the second hemming portion 112 close to the first hemming portion 111. The first end 121 abuts against the groove wall of the first groove 1121a. The first end 121 is provided in the first groove 1121a, which can also be understood as the first end 121 is embedded in the first groove 1121a. Optionally, the first groove 1121a is provided along the extension direction of the second hemming portion 112.

[0079] In this embodiment, by arranging the first end 121 in the first groove 1121a, not only the connection performance between the edging piece 11 and the decorative layer 12 is improved, but also the first groove 1121a can play a role in positioning the decorative layer 12 when preparing the decorative layer 12, thereby reducing the difficulty of preparation and realizing the diversification of the decorative layer 12.

[0080] Please refer to Figure 3-Figure 8 In one embodiment, the second edge portion 112 is further provided with a second groove 1121 b, and the second groove 1121 b is used to accommodate the second end 122 .

[0081] The groove 1121 further includes a second groove 1121b, and the second groove 1121b is provided at a portion of the second edge portion 112 away from the first edge portion 111.

In this embodiment, by limiting the shape of the groove 1121, the decorative layer 12 formed by the polyurethane injection molding material after hardening is difficult to fall off from the groove 1121, and the mechanical clamping force provided by the part of the decorative layer 12 disposed in the groove 1121 is further improved, thereby further improving the connection performance between the edging member 11 and the decorative layer 12.

[0090] Please refer to Fig.10 , Fig.10 A cross-sectional view of an edge wrapping assembly provided in one embodiment of the present application Figure 4In one embodiment, the second edging portion 112 includes a mounting surface 1122 for connecting to the first edging portion 111 and a back surface 1125 opposite to the mounting surface 1122, the mounting surface 1122 is used to mount the decorative layer 12, and the second edging portion 112 is provided with a through hole 1126 penetrating the mounting surface 1122 and the back surface 1125, the through hole 1126 is used to accommodate part of the decorative layer 12.

[0091] The number of through holes 1126 is one or more. When the number of through holes 1126 is multiple, the multiple through holes 1126 are arranged at intervals. The through hole 1126 is located between the first groove 11121a and the second groove 1121b. The through hole 1126 passes through the mounting surface 1122 and the back surface 1125. It can also be understood that the through hole 1126 passes through the second edge portion 112 along the thickness direction of the second edge portion 112. The decorative layer 12 is arranged in the through hole 1126 by an injection molding process to fill the through hole 1126.

[0092] In this embodiment, a through hole 1126 is provided in the second edging portion 112. During the injection molding process, liquid polyurethane injection molding material can flow into the through hole 1126 to fill the through hole 1126. After the liquid polyurethane injection molding material hardens, the portion of the decorative layer 12 provided in the through hole 1126 can provide a fixing mechanical clamping force. The design of the through hole 1126 and the groove 1121 can further improve the connection performance between the edging piece 11 and the decorative layer 12, so that the decorative layer 12 is more firmly fixed to the edging piece 11.

[0093] Please refer to Fig.10 In one embodiment, the decoration layer 12 further includes a limiting portion 123 , which is disposed on the back side 1125 , and is disposed corresponding to the through hole 1126 , and a width of the limiting portion 123 is greater than a diameter of the through hole 1126 .

[0094] The shape of the limiting portion 123 can be circular, quadrilateral, trapezoidal, etc., which is not limited in this embodiment. The limiting portion 123 is arranged outside the through hole 1126, and because the width of the limiting portion 123 is greater than the aperture of the through hole 1126, the position of the decorative layer 12 on the second edge portion 112 is limited to prevent the decorative layer 12 from falling off from the second edge portion 112.

[0095] During the injection molding process, the liquid polyurethane injection molding material can flow to the outside of the through hole 1126 to form a limiting portion 123. After the liquid polyurethane injection molding material hardens, the limiting portion 123 is arranged on the back side 1125 of the second edging portion 112 to prevent the decorative layer 12 from falling off, which can further improve the connection performance between the edging piece 11 and the decorative layer 12, so that the decorative layer 12 can be more firmly fixed on the edging piece 11.

The light emitting portion is arranged on the side 1123 of the light guide strip, and / or on the surface of the light guide strip facing the edging member 11. The extension direction of the light guide strip is the same as the extension direction of the edging member 11.

[0109] The light guide 15 and the edging member 11 are an integrated structure. The light guide 15 and the edging member 11 are injection molded together. For example, a light guide 15 of a certain shape is placed in an edging mold, and is integrally injection molded with the window glass 2 by preparing the edging member 11.

[0110] Specifically, during the preparation of the edging component 1, the light guide 15 is used as an insert and is integrally injection molded with the edging component 11, and then the decorative layer 12 is obtained by injection molding.

In addition, the above-mentioned preparation method does not require the provision of a groove 1121 on the edging component 11 for mechanically clamping the decorative layer 12, which simplifies the structure and improves the preparation efficiency.

[0111] The light guide 15 is obtained by injection molding. Specifically, during the injection molding process, the overall structure and shape of the light guide strip ensure that the light is conducted inside, and by properly arranging one or more LED light sources, uniform light distribution is achieved. For example, by controlling the colors of multiple LED light sources, the overall appearance of the product can present magical colors.

[0112] This embodiment can further improve the aesthetics of the product by arranging the light guide 15 between the decorative layer 12 and the edging member 11. In addition, since the decorative layer 12 has a strong hardness, the scratch resistance of the edging assembly 1 is greatly improved, and the decorative layer 12 can protect the light guide 15 and reduce the probability of damage to the light guide 15.

[0113] Please refer to Figure 13-Figure 16 In one embodiment, the edging member 11 includes a first edging portion 111 and a second edging portion 112 connected to the first edging portion 111, the first edging portion 111 is used to wrap the vehicle window glass 2, the second edging portion 112 is farther away from the vehicle window glass 2 than the first edging portion 111, the light guide member 15 is arranged on one side of the second edging portion 112, the second edging portion 112 is provided with at least one groove 1121 and at least one card groove 1124, the groove 1121 is used to accommodate part of the decorative layer 12, and the card groove 1124 is used to accommodate part of the light guide member 15.

[0114] The light guide 15 includes a third end 151 and a fourth end 152 that are arranged opposite to each other. The fourth end 152 is farther away from the first edge portion 111 than the third end 151. The second edge portion 112 includes a first card slot 1124a and a second card slot 1124b. The first card slot 1124a is used to accommodate the third end 151, and the second card slot 1124b is used to accommodate the fourth end 152.

[0115] In this embodiment, a slot 1124 is formed in the second edging portion 112 of the edging member 11. Part of the light guide member 15 disposed in the slot 1124 can provide a fixed mechanical claw force, so that the light guide member 15 is firmly fixed on the edging member 11, thereby improving the connection performance between the edging member 11 and the light guide member 15.

[0116] Please refer to Figure 13-Figure 16 In one embodiment, the card slot 1124 is connected to the groove 1121 , the depth of the card slot 1124 is greater than the depth of the groove 1121 , and the groove 1121 is formed between the light guide 15 and the second edging portion 112 .

[0117] The first groove 1121a is connected to the first slot 1124a, and the second groove 1121b is connected to the second slot 1124b. The depth of the first slot 1124a is greater than that of the first groove 1121a, and the depth of the second slot 1124b is greater than that of the second groove 1121b.

[0118] This embodiment improves both the connection performance between the edging member 11 and the light guide member 15 and the connection performance between the light guide member 15 and the decorative layer 12 by limiting the position and depth of the groove 1121 and the card slot 1124. In addition, the groove 1121 is formed between the light guide member 15 and the second edging portion 112, so that the decorative layer 12 can better cover the light guide member 15, thereby improving the protective effect of the decorative layer 12 on the light guide member 15.
