The torsion spring is located between the clip seat and the clip seat. The lower part of the clip seat is provided with a clip hole. One end of the torsion spring is inserted into the clip hole.

[0006] The lower trim panel has a slot at the bottom of the body, and a stop block for limiting the torsion spring is provided in the slot. A plate is provided at the bottom front side of the reinforced welded frame of the lower trim panel, and a limiting block is provided on one side of the plate. The left side of the stainless steel shaft pin has a knurled part.

[0007] The luggage compartment sill trim panel has a mounting base at the rear, and a support body is provided on the mounting base. The luggage compartment sill trim panel is snapped onto the support body. There are square notches at both ends of the front part of the luggage compartment sill trim panel, and the square notches are set to correspond to the support body of the mounting base.

[0008] The lower trim panel is reinforced with a welded ABS frame, covered with a skin, and riveted and welded to the main column.

[0009] The lower trim panel encloses the inner wall of the main body and a main body column is provided. The lower trim panel reinforced welded frame has insertion holes, through which the main body column passes and is fixed. The lower trim panel reinforced welded frame has reinforcing ribs.

[0010] Using the technical solution of this invention, the structure is novel, the design is ingenious and simple, the lower trim panel is reinforced with a welded frame, the overall strength is high, the strength required for seating is sufficient, the practicality is high, and the customer experience is high. The luggage compartment sill trim panel and the lower trim panel assembly of the door are installed on the frame, and the middle trim panel and the upper trim panel of the door are installed on the door rotation mechanism. As the door opens, it rotates and opens, and the lower trim panel wraps around the body in a flat shape, providing a large space. Attached Figure Description

[0011] Figure 1 , 2 3 is a structural schematic diagram of the present invention; Figure 4 , 10 This is a structural schematic diagram of the luggage compartment door sill decorative panel and the reinforced welded frame of the present invention; Figure 5 , 11 This is a schematic diagram of the structure of the luggage compartment door sill decorative panel of the present invention; Figure 6 , 7 This is a schematic diagram of the structure of the rear plate of the present invention; Figure 8 , 9 This is a schematic diagram of the front panel of the present invention; Figure 12 , 13 Figures 1 and 14 are schematic diagrams of the structure of an embodiment of the present invention. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0013] like Figure 1 , 2 The following are examples of a car tailgate luggage compartment structure: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14. The tailgate includes a lower trim panel assembly. A luggage compartment carpet 4 is located at the rear of the lower trim panel assembly. The lower trim panel assembly includes a luggage compartment sill trim panel 5. The luggage compartment carpet 4 is mounted on the luggage compartment sill trim panel 5. A row of brackets 7 is located on the front surface of the luggage compartment sill trim panel 5. Stainless steel pins 6 are inserted into the brackets 7. A lower trim panel enclosure body 11 is mounted on the stainless steel pins 6. A lower trim panel reinforcing welded frame 9 is installed on the lower trim panel enclosure body 11.

[0014] The lower trim panel reinforced welded frame 9 has a buckle 8 on the lower front side, and a torsion spring 10 is sleeved on the stainless steel shaft pin 6. The torsion spring 10 is located between the card seat 7 and the card seat 7. The card seat 7 has a card hole at the bottom, and one end of the torsion spring 10 is inserted into the card hole.

[0015] The lower trim panel reinforced welded frame 9 has a slot at its lower part, and a stop block 12 for limiting the torsion spring 10 is provided on the slot. A card plate 14 is provided at the bottom front side of the lower trim panel reinforced welded frame 9, and a limiting block 13 is provided on one side of the card plate 14. A knurled part 15 is provided on the left side of the stainless steel shaft pin 6.

[0016] The luggage compartment sill trim panel 5 is provided with a mounting base at the rear, and a support body 17 is provided on the mounting base. The luggage compartment sill trim panel 5 is snapped onto the support body 17. There are notches at both ends of the front part of the luggage compartment sill trim panel 5, and the notches are set to correspond to the support body 17 of the mounting base.

[0017] The lower trim panel is reinforced with a welded frame made of 9ABS material, with a surface skin covering it, and is riveted and welded to the main column.

[0018] The lower trim panel encloses the inner wall of the main body 11 and has a main body column. The lower trim panel reinforced welded frame 9 has insertion holes through which the main body column passes and is fixed. The lower trim panel reinforced welded frame 9 has reinforcing ribs to improve its strength and stability.

[0019] like Figure 7 , 8 9. In use, the inner wall of the lower trim panel wrapping the body 11 is provided with horizontal and vertical ribs. The horizontal and vertical ribs are divided into square blocks, which facilitates the alignment of the body column on the intersection line and also enhances the strength and firmness of the panel. When the customer opens the top door 2, the bottom door is closed. The middle trim panel 3 and the upper trim panel 16 of the bottom door are installed on the bottom door rotation mechanism. As the bottom door opens, the pivot rotates and opens. There is an opening button 15 on the upper trim panel 16 of the bottom door. When the button 15 is touched, the upper trim panel 16 and the middle trim panel of the bottom door flatten with the pivot. During the rotation, the lower trim panel assembly of the bottom door rests on the middle trim panel of the bottom door and gradually flattens under the action of the torsion spring. The lower trim panel of the bottom door is designed to wrap the body 11. The two are welded together to increase the load-bearing requirements. The lower trim panel wrapping the body 11 can just cover the defects on the back of the car sheet metal, screws, and plastic parts. If the right side of the bumper needs to be repaired, the lower trim panel can also be manually flipped to remove the bumper screws and disassemble and repair the bumper.

[0020] It should be understood that the above description is only a preferred embodiment of the present invention and is not sufficient to limit the technical solution of the present invention. For those skilled in the art, within the spirit and principles of the present invention, additions, subtractions, substitutions, transformations or improvements can be made based on the above description, and all such additions, subtractions, substitutions or improvements should fall within the protection scope of the appended claims of the present invention.
