As shown inFIG.1andFIG.2, the high-integration-level plastic tail door comprises a tail door upper outer plate1, a tail light2, a tail door lower outer plate3, an inner plate4and a high brake light5, wherein the tail door upper outer plate1, as a whole, is integrated with a spoiler1-1, a tail door windshield1-2, a windscreen decorating member1-3and a high brake light cover7; the tail door upper outer plate1is of two layers and is formed by means of double-shot molding, with a first layer being a transparent layer1-A and a second layer being a black non-transparent layer; a first open hole1-B-2is provided at the position of the high brake light5in a black non-transparent layer area, and a second open hole1-B-1is provided in the middle of the tail door windshield1-2, and in this way, the tail door upper outer plate1is partially transparent. Here, the tail door upper outer plate1is integrated with the tail door windshield1-2, the windscreen decorating member1-3, the high brake light5and the spoiler1-1, and is formed by double-shot molding, an outmost layer is the transparent layer1-A, which is mainly made of PC and covers the whole tail door, and the black non-transparent layer is arranged at the position of the spoiler1-1and the position of the windscreen decorating member1-3and is an injection-molded layer mainly made of PC/ABS.

As shown inFIG.3andFIG.4, the tail door upper outer plate1comprises, from left to right, a windshield transparent area1-A-1, a windshield transparent area1-A-2and a windscreen decorating member area1-A-3, wherein the windshield transparent area1-A-1only comprises a single layer with transparent layer1-A, the second open hole1-B-1is located in the windshield transparent area1-A-1, and an inner layer of the windshield transparent area1-A-2and the windscreen decorating member area1-A-3is a black non-transparent layer, is located below the transparent layer, and the inner plate4is adhered to the black non-transparent layer of the tail door upper outer plate1through an adhesive layer6; and as shown inFIG.5, in the area of the spoiler1-1, the inner plate4is adhered to the tail door upper outer plate1through the adhesive layer6, the tail door upper outer plate1is only provided with a single layer with transparent layer1-A at the position of the high brake light5, the first open hole1-B-2is formed in the black non-transparent layer beside the high brake light5, a high brake mounting structure8is disposed on the periphery of the black non-transparent layer, and the high brake light5is mounted on the high brake mounting structure8from an inner side of the tail door upper outer plate. Here, the first open hole1-B-2is formed in the black non-transparent layer at the position of the high brake light2on the tail door upper outer plate1, so that the transparency of this position is guaranteed; the high brake mounting structure8is arranged around the first open hole, and the tail light2is mounted on the outer plate from the inner side; and the transparent layer1-A is able to function as an original light cover, is integrated with the high brake light cover7, and fulfills a better sealing effect and a better appearance effect.

As shown inFIG.6, the transparent layer1-A at a lower end of the tail door upper outer plate1and the black non-transparent layer below the transparent layer1-A extend below the tail light2and are adhered to the tail door lower outer plate3through the adhesive layer6, and the inner plate4is adhered to the tail door lower outer plate3through the adhesive layer6; the black non-transparent layer is formed with an open hole in the windshield transparent area1-A-1, so that a transparency effect is realized. A hardened coating is disposed on an outer layer of the transparent layer1-A. The hardened coating is additionally arranged on the tail door upper outer plate1mainly through shower coating or spray coating, so that the scratch resistance of the tail door is guaranteed. Paint does not need to be sprayed onto the tail door upper outer plate1anymore, and both the integrity and texture of the appearance are improved.

The windscreen decorating member1-3is formed integrally by injection-molding or is installed piece by piece. As shown inFIG.7andFIG.8, to facilitate the installation of the windscreen decorating member1-3, the windscreen decorating member1-3is provided with a positioning structure, a YZ-direction positioning pin3-1is disposed on a surface of the spoiler1-1, a YZ-direction positioning hole3-3is formed in the windscreen decorating member1-3, a Y-direction auxiliary positioning pin3-2is disposed on a surface of the inner plate4, the spoiler1-1is adhered to the inner plate4with an adhesive to form a tail door body, and in this way, the spoiler1-1and the inner plate4are assembled into a whole; and then, the Y-direction auxiliary positioning pin is used for auxiliary positioning before assembly to enable the YZ-direction positioning pin3-1on the windscreen decorating member1-3to match the YZ-direction positioning hole3-3in the windscreen decorating member1-3for positioning, so that the windscreen decorating member1-3, the spoiler1-1and the inner plate4are assembled together. Here, since the Y-direction auxiliary positioning pin is formed on the inner plate4, and the YZ-direction positioning pin3-1is formed on the spoiler1-1, so that the windscreen decorating member1-3is smaller and lighter, the assembly clearance of the windscreen decorating member1-3is effectively guaranteed, and a good appearance is guaranteed.

As shown inFIG.9andFIG.10, the windscreen decorating member1-3is assembled on the tail door body formed by adhering the spoiler1-1to the inner plate4, an upward bevel is formed between the YZ-direction positioning pin3-1and the windscreen decorating member1-3in a horizontal direction, so that the windscreen decorating member1-3can be pre-hanged on the YZ-direction positioning pin3-1by means of its gravity when assembled, which means that a pre-hanging effect is realized; and then, the windscreen decorating member1-3is tightened, so that installation is easier and faster.

As shown inFIG.11andFIG.12, a metal reinforcing plate is disposed on a visible side of the inner plate4, that is, the metal reinforcing plate is mounted on a side fitting a mold during injection-molding of a mold insert of the tail door inner plate4, and as shown inFIG.1andFIG.2, mainly comprises a pillar reinforcing plate9, a hinge reinforcing plate10and a ball pin reinforcing plate11, wherein the hinge reinforcing plate10and the ball pin reinforcing plate11are electrically welded to an upper end and a lower end of the pillar reinforcing plate9respectively, and the hinge reinforcing plate10and the ball pin reinforcing plate11are both 2 mm galvanized steel sheets, so that the lightweight effect of the whole metal reinforcing plate is good, materials are saved, and the weight and cost are reduced; the hinge reinforcing plate10is formed with a hinge mounting hole12, an internal decorating member mounting hole13is formed in a lower end of the hinge reinforcing plate10on the pillar reinforcing plate9, a first auxiliary positioning hole14is formed beside the internal decorating member mounting hole13, a second auxiliary positioning hole16is formed in a lower end of the pillar reinforcing plate9, and the first auxiliary positioning hole14and the second auxiliary positioning hole16are located on the same plane. Here, the internal decorating member mounting hole13facilitates the installation and fixation of an internal decorating member, and the auxiliary positioning holes are used for auxiliary positioning and installation, so that installation is easy and fast.

As shown inFIG.13, a first flange18and a second flange17used for improving the stiffness of the pillar reinforcing plate9are disposed on two sides of the pillar reinforcing plate9, and a U-groove structure is formed by the first flange18, the second flange17and the pillar reinforcing plate9, wherein the first flange18is located on a right side, the second flange17is located on a left side, the first flange18extends to a tail end of an area, where the hinge reinforcing plate10is located, from the position of the ball pin reinforcing plate11, the second flange17extends to a platform area, where the first auxiliary positioning hole14is located, from an area where the second auxiliary positioning hole16is located, and the width of the first flange18and the second flange17is greater than 20 mm. In this way, the flanges on the two sides of the pillar reinforcing plate11have a large size, which guarantees uniform and good stiffness. The ball pin reinforcing plate11is formed with a ball pin mounting hole15, and the ball pin reinforcing plate11and the pillar reinforcing plate9of a triangular structure, so that the same stiffness is realized, and the design of the metal reinforcing part of the plastic tail door is simplified.
