For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0043] In one embodiment of the present invention, a resin tailgate is disclosed. As Figure 1 and Figure 2 shown, it includes an inner tailgate panel 1, an outer tailgate panel 2, and a tailgate glass 3. The outer tailgate panel 2 includes an upper outer panel 21 and a lower outer panel 22. The upper outer panel 21 and the lower outer panel 22 are respectively bonded to the inner tailgate panel 1, and the upper outer panel 21 is disposed above the lower outer panel 22.

[0044] As Figure 2 and Figure 5 shown, a break 20 communicating with the inner tailgate panel 1 is formed by separating between the upper outer panel 21 and the lower outer panel 22. The upper part of the tailgate glass 3 is bonded to the upper outer panel 21, the lower part of the tailgate glass 3 is bonded to the lower outer panel 22, and the middle part of the tailgate glass 3 covers the break 20 and is bonded to the inner tailgate panel 1.

[0045] Furthermore, as Figure 2 shown, a window frame 10 is provided in the upper half of the inner tailgate panel 1. The tailgate glass 3 is used to cover the window frame 10. The break 20 is provided in the middle of the upper half of the inner tailgate panel 1, that is, preferably, the break 20 is provided at the middle position of the window frame 10. The upper outer panel 21 and the lower outer panel 22 are separated to form the break 20, and the length of the break 20 is set to be less than the Z - direction height of the window frame 10. Among them, by separating the outer tailgate panel 2 into the upper outer panel 21 and the lower outer panel 22, the weight of the outer tailgate panel 2 in the present application can be made lighter compared to the integrally formed outer tailgate panel 2, and the upper outer panel 21 and the lower outer panel 22 can be separately injection - molded. The injection - molding volume is smaller, and an injection - molding machine with a smaller tonnage can be used for injection - molding, which is beneficial to reducing the investment in injection - molding equipment. At the same time, the rigidity of the injection - molded outer tailgate panel 2 can be better, the part precision can be improved, and the overall structural strength of the tailgate can be enhanced.

[0046] In addition, as Figure 5As shown, the upper outer panel 21 and the lower outer panel 22 are directly bonded to the inner tailgate panel 1. The tailgate glass 3 is directly connected to the upper outer panel 21, the lower outer panel 22, and the inner tailgate panel 1 at the notch 20 by bonding, which can make the assembly between the tailgate glass 3, the outer tailgate panel 2, and the inner tailgate panel 1 easier. At the same time, the tailgate glass 3 covers the notch 20 and is bonded to the inner tailgate panel 1 at the notch 20, making the appearance performance of the tailgate better. At the same time, the bonding method can make the waterproof effect of the tailgate better, preventing external rainwater from entering the carriage interior through the connection gaps between the inner tailgate panel 1, the outer tailgate panel 2, and the tailgate glass 3.

[0047] Wherein, in the present application, the X direction refers to the length direction of the vehicle, the Y direction refers to the width direction of the vehicle, the Z direction refers to the height direction of the vehicle, the outer surface refers to the surface facing the outside of the carriage, and the inner surface refers to the surface facing the inside of the carriage.

[0048] In some embodiments of the present invention, as Figure 2 shown, the inner tailgate panel 1 is provided with a window frame 10. The upper outer panel 21 is bonded to the outer periphery of the upper part of the window frame 10, at least part of the lower outer panel 22 is bonded to the outer periphery of the lower part of the window frame 10, the notch 20 is arranged in the middle of the side surface of the window frame 10, and the tailgate glass 3 covers the window frame 10.

[0049] Wherein, the tailgate glass 3 covers at least part of the upper outer panel 21 and at least part of the lower outer panel 22. Further, as Figure 2 shown, the upper outer panel 21 includes a first connecting portion 212, the lower outer panel 22 includes a second connecting portion 222. Both the first connecting portion 212 and the second connecting portion 222 are arranged on the side surface of the window frame 10, and the first connecting portion 212 and the second connecting portion 222 are separated from each other to form the notch 20. As Figure 6 and Figure 7 shown, the upper part of the tailgate glass 3 is bonded to the first connecting portion 212, the lower part of the tailgate glass 3 is bonded to the second connecting portion 222, and the middle part of the tailgate glass 3 is bonded to the inner tailgate panel 1 through the notch 20.

[0050] In some embodiments of the present invention, as Figure 3 shown, the inner tailgate panel 1 is provided with a bending portion 11 that bends in the direction towards the tailgate glass 3, and the bending portion 11 covers the side surface of the outer tailgate panel 2 covered by the tailgate glass 3.

[0051] Further, as Figure 3As shown, the bent portion 11 bends outward along the X direction towards the tailgate glass 3, so that the bent portion 11 can wrap the side surface of the outer tailgate panel 2. Among them, the length of the bent portion 11 is greater than the distance between the outer surface of the outer tailgate panel 2 and the inner tailgate panel 1 by at least 1 mm, so that the bent portion 11 can block external rainwater from entering the carriage interior between the inner tailgate panel 1 and the outer tailgate panel 2, thus achieving a good waterproof effect.

[0052] Furthermore, bent portions 11 are provided on both the inner and outer sides of the first connecting portion 212 and the second connecting portion 222. The bent portions 11 bend towards the direction of the tailgate glass 3 and wrap the inner and outer edges of the first connecting portion 212 and the second connecting portion 222, thereby preventing external rainwater from entering the carriage interior through the connection gaps between the outer tailgate panel 2, the inner tailgate panel 1, and the tailgate glass 3.

[0053] In addition, as Figure 4 shown, the inner tailgate panel 1 at the fracture 20 is also provided with a bent portion 11, which can play a role in blocking water.

[0054] In some embodiments of the present invention, as Figure 5 shown, the inner surface of the upper outer panel 21 is adhesively fixed to the outer surface of the inner tailgate panel 1 through the first adhesive portion 211, and the inner surface of the lower outer panel 22 is adhesively fixed to the outer surface of the inner tailgate panel 1 through the second adhesive portion 221. As Figure 6 and Figure 7 shown, the upper part, the lower part, and the middle part of the tailgate glass 3 are adhesively fixed to the outer surface of the upper outer panel 21, the outer surface of the lower outer panel 22, and the inner tailgate panel 1 respectively through the third adhesive portion 31;

[0055] The first adhesive portion 211 and the third adhesive portion 31 are connected together at the upper end of the fracture 20, and the second adhesive portion 221 and the third adhesive portion 31 are connected together at the lower end of the fracture 20.

[0056] Furthermore, the third adhesive portion 31 is arranged along the contour edge of the tailgate glass 3, so that the upper part of the tailgate glass 3 can be firmly fixed to the outer surface of the upper outer panel 21 through the third adhesive portion 31, and the lower part of the tailgate glass 3 can be firmly fixed to the inner surface of the lower outer panel 22 through the third adhesive portion 31. Among them, the thickness of the third adhesive portion 31 arranged at the fracture 20 position is greater than the thickness of the other parts of the third adhesive portion 31, so that the middle part of the tailgate glass 3 can be directly adhesively fixed to the inner tailgate panel 1 through the fracture 20. By arranging the third adhesive portion 31 along the contour edge of the tailgate glass 3, the watertightness of the contour edge of the tailgate glass 3 can be improved, and the third adhesive portion 31 can block external rainwater from entering the carriage interior through the edge of the tailgate glass 3.

[0057] In addition, the first adhesive part 211 is arranged along the contour edge of the upper outer panel 21, and the second adhesive part 221 is arranged along the contour edge of the lower outer panel 22. Through the first adhesive part 211 and the second adhesive part 221, the upper outer panel 21 and the lower outer panel 22 can be firmly fixed to the inner tailgate panel 1, and at the same time, through the first adhesive part 211 and the second adhesive part 221, the contour edges of the upper outer panel 21 and the lower outer panel 22 can be sealed, thereby preventing external rainwater from entering the carriage interior through the contour edges of the upper outer panel 21 and the lower outer panel 22.

[0058] Among them, as Figure 7 shown, at least part of the first adhesive part 211 enters the upper end of the fracture 20 and is connected to the third adhesive part 31 at the fracture 20, and at least part of the second adhesive part 221 enters the lower end of the fracture 20 and is connected to the third adhesive part 31 at the fracture 20, thereby improving the watertightness at the junction of the upper outer panel 21 and the lower outer panel 22 with the fracture 20, and enabling the tailgate to have a better watertight effect.

[0059] Furthermore, a shielding layer is provided at the part where the first adhesive part 211, the second adhesive part 221, and the third adhesive part 31 are arranged on the tailgate glass 3. The shielding layer can be a black coating for shielding the first adhesive part 211, the second adhesive part 221, the third adhesive part 31, and the inner tailgate panel 1 and the outer tailgate panel 2 seen through the tailgate glass 3, thereby improving the aesthetics of the tailgate.

[0060] In some embodiments of the present invention, as Figure 8 shown, the inner tailgate panel 1 is provided with a connecting frame 12 arranged outward along the Y direction. The inner surface of the lower outer panel 22 is adhesively fixed to the connecting frame 12, and an installation cavity is formed between the inner tailgate panel 1 and the lower outer panel 22.

[0061] Furthermore, as Figure 8 shown, the inner tailgate panel 1 includes an upper inner panel 13 and a lower inner panel 14. The upper inner panel 13 is arranged above the lower inner panel 14. The window frame 10 is arranged in the upper inner panel 13, and the connecting frame 12 is arranged in the lower inner panel 14. Among them, a taillight installation part 16 for installing a taillight is formed between the connecting frame 12 and the window frame 10. The taillight installation part 16 is arranged at the upper end of the lower inner panel 14, and the fracture 20 is arranged above the taillight installation part 16.

[0062] Still further, as Figure 8As shown in the figure, the connecting frame 12 is arranged in the middle of the inner panel lower plate 14 and is used to connect with the middle of the outer panel lower plate 22. The connecting frame 12 is integrally formed with the inner tailgate panel 1 and is arranged on the outer surface of the inner tailgate panel 1 and extends outward. A third adhesive portion 31 is arranged on the connecting frame 12. Through the third adhesive portion 31, the inner surface of the middle part of the outer panel lower plate 22 can be adhesively fixed on the connecting frame 12, so that the connecting frame 12 provides a supporting effect for the middle position of the outer panel lower plate 22, thereby improving the structural strength of the tailgate and the connection stability between the inner tailgate panel 1 and the outer tailgate panel 2.

[0063] Among them, by arranging the connecting frame 12, an installation cavity for installing components in the tailgate is formed between the inner panel lower plate 14 and the outer panel lower plate 22.

[0064] In some embodiments of the present invention, as Figure 8 shown, the connecting frame 12 includes a first support rib 121, a second support rib 122, and a third support rib 123. The first support rib 121 is arranged above the second support rib 122, and the third support rib 123 is connected between the first support rib 121 and the second support rib 122. The first support rib 121, the second support rib 122, and the third support rib 123 form a frame structure and are respectively connected to the outer surface of the inner panel and the inner surface of the outer panel lower plate 22.

[0065] Furthermore, as Figure 8 shown, the first support rib 121, the second support rib 122, and the third support rib 123 are all arranged on the outer surface of the inner panel lower plate 14 and extend outward. The first support rib 121 and the second support rib 122 are respectively arranged along the Y direction. Two third support ribs 123 are respectively arranged on both sides of the first support rib 121 and the second support rib 122. One end of the third support rib 123 is connected to the end of the first support rib 121, and the other end of the third support rib 123 is connected to the end of the second support rib 122, so that the first support rib 121, the second support rib 122, and the third support rib 123 form a frame structure in the shape of a trapezoid, a square, or a rectangle.

[0066] Optionally, a plurality of connecting frames 12 can be arranged on the inner tailgate panel 1, so as to increase the connection stability between the inner tailgate panel 1 and the outer tailgate panel 2. At the same time, the size and shape of the connecting frame 12 can also be adjusted according to the installation layout of the components.

[0067] In some embodiments of the present invention, as Figure 8 shown, a plurality of first reinforcing ribs 17 are arranged on the outer periphery and inside of the connecting frame 12.

[0068] Among them, by setting the first reinforcing rib 17, the strength of the connecting frame 12 can be enhanced, and further the connection stability between the inner tailgate panel 1 and the outer tailgate panel 2 can be enhanced.

[0069] Preferably, the first reinforcing rib 17 is set in a triangular shape, which has high stability and support effect, thereby improving the structural strength of the connecting frame 12.

[0070] Furthermore, as Figure 8 shown, the first reinforcing rib 17 is also arranged between the window frame 10 and the connecting frame 12, thereby improving the structural strength of the taillight mounting portion 16.

[0071] Still further, a second reinforcing rib is provided on the inner surface of the outer panel lower plate 22. The second reinforcing rib is triangular. By setting the second reinforcing rib, the structural strength and rigidity of the outer tailgate panel 2 can be further enhanced.

[0072] In some embodiments of the present invention, as Figure 9 shown, the inner tailgate panel 1 is provided with a door lock mounting portion 15 for mounting a door lock. A reinforcing bracket 151 is provided on the door lock mounting portion 15. As Figure 10 shown, the reinforcing bracket 151 includes two reinforcing members 1511 symmetrically arranged along the Z direction. An included angle α is formed between the reinforcing member 1511 and the Z direction. Both ends of the reinforcing member 1511 are respectively connected to the inner tailgate panel 1.

[0073] Among them, as Figure 9 and Figure 10 shown, the reinforcing member 1511 is arranged substantially along the Z direction, and the two reinforcing members 1511 are arranged in a substantially V shape. By setting the reinforcing bracket 151, the impact resistance of the door lock mounting portion 15 can be improved.

[0074] Furthermore, when a force F0 in the Z direction acts on the door lock mounting portion 15, the force F0 acting on the reinforcing bracket 151 forms component forces F1 along the two reinforcing members 1511 respectively, and F1 = F0 / 2cosα. Therefore, on the premise of meeting the design of avoiding parts, the smaller α is, the better.

[0075] In some embodiments of the present invention, as Figure 11 shown, a door lock mounting frame 152 is provided on the inner tailgate panel 1. The door lock mounting frame 152 includes a first connecting plate 1521 and a second connecting plate 1522. The first connecting plate 1521 and the second connecting plate 1522 are connected to form an L-shaped structure. The first connecting plate 1521 has a first connection point 1523, and the second connecting plate 1522 has a second connection point 1524. The first connection point 1523 and the second connection point 1524 are respectively fixedly connected to the inner tailgate panel 1.

[0076] In some embodiments of the present invention, as Figure 10 andFigure 11 As shown, the reinforcement member 1511 includes a first connection end 1512 and a second connection end 1513. The first connection end 1512 is fixedly connected to the inner tailgate panel 1, and the second connection end 1513 and the second connection point 1524 are fixed at the same position on the inner tailgate panel 1. A triangular support structure as shown by the dashed line is formed between the reinforcement member 1511 and the first connection point 1523 and the second connection point 1524. Figure 11 The triangular support structure shown by the dashed line.

[0077] Among them, by forming a triangular support structure between the reinforcement member 1511 and the first connection point 1523 and the second connection point 1524, the structural strength of the door lock mounting bracket 152 is further improved.

[0078] The above are only the principles and preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, based on the principles of the present application, several other variations can also be made, which should also be regarded as the protection scope of the present application.
