For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0059] In the related art, the appearance surface of the edge covering element without bright decorative strips is difficult to achieve high black and bright effect. If bright decorative strips are used, the appearance modeling is difficult to realize diversification due to the forming process thereof. Moreover, the forming process of the bright decorative strips limits the dimensional accuracy of the product, and the integral injection molding with the edge covering element is prone to cause flash, which is easy to scratch the appearance surface of the bright decorative strips in the later trimming. In addition, if the edge covering element is too thick, it is prone to shrink and deform, thereby pulling the surface of the bright decorative strips, causing light distortion of the bright decorative strips, and affecting the product appearance. Therefore, the decorative layer is used instead of the bright decorative strips in the related art in the present application, which not only can improve the product appearance, but also can realize diversification and reduce cost.

The wrapping assembly 1 includes a wrapping member 11 and a decorative layer 12 disposed on one side of the wrapping member 11. The wrapping member 11 is used to wrap the vehicle window glass 2. The decorative layer 12 is used to decorate the vehicle, and the decorative layer 12 is obtained by injection molding of a polyurethane injection molding material.

[0062] The wrapping assembly 1 according to the embodiment of the present application includes the wrapping member 11 used to wrap the vehicle window glass 2. The material of the wrapping member 11 includes at least one of PU, PVC, and TPE. The wrapping member 11 is obtained by injection molding. The shape of the wrapping member 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 an angle window glass, or a rear windshield, or a sunroof glass, etc. Optionally, the wrapping member 11 includes a first wrapping portion 111 used to wrap the vehicle window glass 2, and a second wrapping portion 112 connected to the first wrapping portion 111. The second wrapping portion 112 is used to lap the body fitting member of the vehicle.

[0063] The hardness of the wrapping member 11 is less than the hardness of the decorative layer 12. Optionally, the hardness of the wrapping 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 wrapping assembly 1 according to the embodiment of the present application further includes the decorative layer 12 used to decorate the vehicle. The decorative layer 12 is obtained by injection molding 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 a liquid. The decorative layer 12 can be transparent to light, or the decorative layer 12 has a specific color so as to be opaque to light. The decorative layer 12 can be disposed on the outside of the vehicle as an exterior decoration of the vehicle. The decorative layer 12 can also be disposed on the inside of the vehicle as an interior decoration of the vehicle.

[0065] In one embodiment, as shown in Figure 5 the thickness T of the decorative layer 12 satisfies the following condition in the stacking direction from the wrapping member 11 to the decorative layer 12: 0.2mm≤T≤2mm.

[0066] For example, the thickness T of the decorative layer 12 can be 0.2 mm, or 0.4 mm, or 0.6 mm, or 0.8 mm, or 1 mm, or 1.2 mm, or 1.4 mm, or 1.6 mm, or 1.8 mm, or 2 mm, etc. By limiting the thickness of the decorative layer 12 to 0.2-2 mm, the decorative layer 12 can have a relatively thin high-gloss surface, and the production cost can be reduced.

[0067] The polyurethane injection molding material has a sufficiently low viscosity and high fluidity, so the injection molding pressure is small, and the material can be applied to the surface of the trim part 11 as a surface coating. The surface of the decorative layer 12 thus obtained can exhibit typical high gloss and brilliant 3-D depth and a luxurious appearance effect, the surface of the decorative layer 12 itself is smooth and bright, the surface visual effect is more beautiful, the appearance of the vehicle is improved, and the pursuit of high-quality perfect appearance by consumers is met. Moreover, the decorative layer 12 does not need additional polishing treatment, the production cost is reduced, and the production efficiency is improved.

[0068] In addition, the polyurethane has a self-repairing property. If the decorative layer 12 has surface scratches due to improper use, the self-healing effect of the 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 the scratch resistance is greatly improved.

[0069] In addition, the polyurethane has a self-repairing property. If the decorative layer 12 has surface scratches due to improper use, the self-healing effect of the 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 the scratch resistance is greatly improved.

[0070] Therefore, by providing the decorative layer 12 obtained by the injection molding process of the polyurethane injection molding material on the trim part 11, the present embodiment is convenient for processing and production, does not need to use the bright trim strip in the related art, reduces the production cost and improves the appearance of the product. Moreover, the decorative layer 12 has a relatively high hardness, can overcome the shrinkage problem caused by the trim part 11, enhances the dimensional stability of the trim assembly 1, can effectively avoid the problem of surface light distortion of the black bright trim strip, and can effectively improve the durability of the trim assembly 1.

The decorative layer 12 is arranged on the surface of the second edge covering portion 112 and in the groove 1121. The number of the groove 1121 is one or more.

[0073] Due to the incompatibility between the material of the edge covering member 11 and the material of the decorative layer 12, the connection between the edge covering member 11 and the decorative layer 12 is poor. In the embodiment, the groove 1121 is arranged on the second edge covering portion 112 of the edge covering member 11. In the injection molding process, the liquid polyurethane injection material can flow into the groove 1121 to fill the groove 1121. After the liquid polyurethane injection material hardens, the part of the decorative layer 12 arranged in the groove 1121 can provide a fixed mechanical clamping force, so that the decorative layer 12 is firmly fixed on the edge covering member 11, and the connection between the edge covering member 11 and the decorative layer 12 is improved.

[0074] In an embodiment, as shown in Figure 6 the depth H1 of the groove 1121 satisfies the following conditions: 0.5mm≤H1≤3mm; and / or, the opening width H2 of the groove 1121 satisfies the following conditions: 0.5mm≤H2≤3mm.

[0090] Please refer to Figure 10 , Figure 10 A cross-sectional view of the trim part according to an embodiment of the present application Figure 4In an embodiment, the second edge covering part 112 comprises a mounting surface 1122 for connecting the first edge covering part 111, and a back surface 1125 opposite to the mounting surface 1122, the mounting surface 1122 is used for mounting the decorative layer 12, the second edge covering part 112 is provided with a through hole 1126 penetrating through the mounting surface 1122 and the back surface 1125, the through hole 1126 is used for accommodating 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 more, the plurality of 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 penetrates the mounting surface 1122 and the back surface 1125, and it can also be understood that the through hole 1126 penetrates the second edge covering part 112 along the thickness direction of the second edge covering part 112. The decorative layer 12 is arranged in the through hole 1126 by the injection molding process, and fills the through hole 1126.

[0092] In the embodiment, by arranging the through hole 1126 in the second edge covering part 112, in the injection molding process, the liquid polyurethane injection material can flow into the through hole 1126 to fill the through hole 1126. After the liquid polyurethane injection material hardens, part of the decorative layer 12 arranged in the through hole 1126 can provide a fixed mechanical clamping force. The design of the through hole 1126 cooperates with the groove 1121 to further improve the connection performance between the edge covering part 11 and the decorative layer 12, so that the decorative layer 12 is more firmly fixed on the edge covering part 11.

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

[0095] In the injection molding process, the liquid polyurethane injection material can flow outside the through hole 1126 to form the limiting part 123. After the liquid polyurethane injection material hardens, the limiting part 123 is arranged on the back surface 1125 of the second edge covering part 112, preventing the decorative layer 12 from falling off, and further improving the connection performance between the edge covering part 11 and the decorative layer 12, so that the decorative layer 12 is more firmly fixed on the edge covering part 11.

The roughening treatment can be performed on the surface of the edging piece using mechanical or chemical methods (mechanical abrasion or chemical corrosion). For example, a smooth layer on the surface of the edging piece 11 can be sanded away to form the roughened area 113.

[0104] This embodiment improves the bonding force and connection performance between the edging piece 11 and the decorative layer 12 by providing a roughened area 113 on the edging piece 11 and a decorative layer 12 on the roughened area 113.

[0105] Optionally, the edging assembly 1 further includes an adhesive layer 13 disposed in the rough area 113, the adhesive layer 13 being used to bond the decorative layer 12 to the edging component 11. This embodiment, by disposing the adhesive layer 13 in the rough area 113 and then using the adhesive layer 13 to bond the edging component 11 to the decorative layer 12, can further improve the connection performance between the edging component 11 and the decorative layer 12.

[0106] Please refer to this as well. Figures 13-16 , Figure 13 A cross-sectional view of the edge-binding component provided in one embodiment of this application. Figure 7 .

[0117] The first groove 1121a communicates with the first clamping groove 1124a, and the second groove 1121b communicates with the second clamping groove 1124b. Among them, the depth of the first clamping groove 1124a is greater than the depth of the first groove 1121a, and the depth of the second clamping groove 1124b is greater than the depth of the second groove 1121b.

[0118] The present embodiment limits the position and depth of the groove 1121 and the clamping groove 1124, which improves the connection performance between the edge covering part 11 and the light guide 15, and improves the connection performance between the light guide 15 and the decorative layer 12. Moreover, the groove 1121 is formed by surrounding the light guide 15 and the second edge covering part 112, so that the decorative layer 12 can better cover the light guide 15, and the protection of the decorative layer 12 to the light guide 15 is improved.
