[0032] The tailgate, also known as the rear door or tailgate, is a crucial component of a vehicle's body structure. Located at the rear of the vehicle, it serves to close the trunk opening. During the design and development of the vehicle structure, a decorative panel is required to enhance the overall visual quality and upscale feel of the interior, as well as to protect the metal structure inside the tailgate from damage. However, existing decorative panels are typically manufactured using traditional injection molding techniques. The inventors have learned that this not only hinders vehicle lightweighting but, due to its inherent structural characteristics, can easily deform when manufactured using new processes (such as gas-assisted injection molding).

[0033] In order to solve the problem that the decorative panels are easily deformed during the manufacturing process, it is necessary to improve or optimize the structure of the decorative panels.

[0034] Example 1

[0035] See also Figures 1 to 4 The embodiment of the first aspect of the present invention provides a tailgate interior panel connection assembly, which includes a trim panel 1 for connecting to the side of the tailgate closer to the inside of the vehicle. It should be noted that the side of the tailgate closer to the inside of the vehicle refers to the sheet metal structure on the inside of the tailgate where the rear windshield of the vehicle is located. Specifically, the trim panel 1 includes a trim panel body 11 and a partition 12, wherein the trim panel body 11 is in the shape of a long strip and has a U-shaped cross section, and the partition 12 is connected to or integrally formed with the trim panel body 11, and when viewed from the inside of the vehicle to the outside of the vehicle, the partition 12 is located on the trim panel body 11 on the side closer to the outside of the vehicle.

[0036] In this embodiment, to address the problem of deformation of the decorative panel 1 during manufacturing using a gas-assisted injection molding process, an air channel 13 is formed between the decorative panel body 11 and the partition 12 for communication with a gas supply device. It should be noted that the gas supply device referred to herein is a key component of the gas-assisted injection molding (GAIM) system and primarily comprises an air pump, a high-pressure gas generator, a gas control device, and a gas nozzle. The air pump, as the source of gas supply, continuously compresses gas to provide a stable air pressure output; the high-pressure gas generator is used to generate high-pressure gas to meet the gas pressure requirements during the injection molding process; the gas control device, including a compressor and an electrically controlled valve, is used to continuously supply gas and maintain a constant gas pressure. It can also precisely control the injection time and pressure of the high-pressure gas based on the injection signal from the injection molding machine; and the gas nozzle is the component used to inject the high-pressure gas into the molten plastic. Thus, during the gas-assisted injection molding process, the injection molding machine applies high pressure to the plasticized molten plastic (i.e., in a viscous flow state) with the help of the thrust of the screw (or plunger), causing the molten plastic to be ejected and injected into the closed mold cavity. When the molten plastic fills the mold cavity to a certain extent, the gas supply device begins to inject high-pressure inert gas (usually nitrogen) into the mold cavity. These gases form a hollow cross-section in the mold cavity and push the molten plastic forward to continue filling the mold cavity until it is full. At the same time, a relatively low-pressure gas is used to maintain pressure, so that the molten plastic is formed into a plastic product using the molding mold. Compared to existing decorative panels manufactured using traditional injection molding processes, the decorative panel 1 disclosed in the present invention, due to the presence of the air channel 13, is not only easy to manufacture using the gas-assisted injection molding process, but also can solve deformation problems caused by residual stress and warping due to the use of gas pressure maintenance instead of traditional plastic pressure maintenance during the molding process.

[0037] Specifically, the air duct 13 extends along the length direction of the decorative panel 1 and penetrates the decorative panel 1. In order to ensure the strength and appearance of the decorative panel 1 manufactured by the gas-assisted injection molding process, preferably, the width of the cross section of the air duct 13 is 1 mm to 20 mm.

[0038] Furthermore, in order to reduce the flow resistance of the gas in the gas channel 13 , the surface of the partition 12 on the side of the gas channel 13 is a curved surface.

[0039] like Figure 3 、 Figure 4 and Figure 5As shown, in order to connect with the tailgate, the tailgate interior panel connection assembly also includes a base 2 and a buckle 3 that is engaged with the base 2, so that the decorative panel 1 can be engaged with the tailgate through the base 2 and the buckle 3. Specifically, the base 2 includes a base body 21, a support rib 22, and a flange 23. The base body 21 is truncated cone-shaped, hollow inside, and has a radially extending slot 24 on the top for engaging with the buckle 3. The support rib 22 protrudes radially from the inner surface of the base body 21 and extends along the length of the base body 21 to support and limit the buckle 3. The flange 23 is located at the edge of the base body 21 near one end of the decorative panel body 11 and extends outward away from the base body 21 to be fixedly connected to the partition 12 and the decorative panel body 11. The buckle 3 includes a buckle body 31, a first limiting portion 32, a second limiting portion 33, and a third limiting portion 34. The buckle body 31 is cylindrical, with the first limiting portion 32 located at one end of the buckle body 31 near the base 2, and the second and third limiting portions 33, 34 located in the middle of the buckle body 31. The first, second, and third limiting portions 33, 34 all extend radially outward from the outer surface of the buckle body 31. It should be noted that the first and second limiting portions 32, 33 engage the base 2, while the third limiting portion 34 contacts the rear door. Preferably, the diameters of the first, second, and third limiting portions 32, 33, 34 increase sequentially to ensure the stability of the connection between the buckle 3, the base 2, and the rear door. In this way, when the decorative panel 1 needs to be installed on the tailgate, the base 2 is first fixedly connected to the partition 12 and the decorative panel body 11 through the flange 23, and then the first limiting part 32 and the second limiting part 33 are clamped to the base 2 to complete the clamping of the clip 3 and the base 2. At this time, the first limiting part 32 is inserted into the slot 24, the support rib 22 abuts against the bottom surface of the first limiting part 32, and the second limiting part 33 abuts against the top outer surface of the base body 21. Finally, the clip body 31 of the clip 3 is matched with the adapter hole of the tailgate, so that the third limiting part 34 abuts against the corresponding mating surface on the tailgate, and the connection between the decorative panel 1 and the tailgate can be realized to decorate and protect the sheet metal structure inside the tailgate.

[0040] Since the sheet metal structure inside the tailgate typically has a folded edge, in this embodiment, a receiving groove 14 is formed between the trim body 11 and the partition 12 to accommodate the folded edge. The notch of the receiving groove 14 faces outward from the vehicle and is arranged in parallel with the air duct 13. It should be noted that to ensure the implementation of the gas-assisted injection molding process, the base 2 and the buckle 3 are both located in the receiving groove 14, which helps to avoid the base 2 and the buckle 3 occupying the space of the air duct 13.

[0041] In this embodiment, in order to ensure that the buckle 3 is adapted to the corresponding adapter hole on the back door, a positioning pin 15 is formed on one side of the accommodating groove 14 of the partition 12, and a positioning groove 25 is provided on the flange 23 of the base 2, so that the base 2 can be installed at a preset position through the cooperation of the positioning groove 25 and the positioning pin 15, thereby ensuring that the buckle 3 engaged with the base 2 can pass through the corresponding adapter hole on the back door.

[0042] In some embodiments, there may be more than one positioning pin 15 . In this embodiment, there are two positioning pins 15 .
