Figure 1 In the open state of the left figure, the first end 111 of the sheet metal 11 is shielded by the baffle structure 2 , so that the baffle structure 2 and the first trim panel 12 provide occupant support and appearance.

[0028] like Figure 3 As shown, the fender structure 2 includes a back sill 21, wherein the back sill 21 is fixedly mounted on the rear of the vehicle body, and the fender structure 2 is rotatably mounted on the back sill 21 to define a Figure 1 The open and closed states are shown.

[0029] like Figure 4 As shown, the baffle structure 2 includes a second trim panel 221, a bracket 222, a hinge assembly 223 and a felt strip 224, wherein the second trim panel 221 provides the above-mentioned appearance surface, and the bracket 222 is for example welded under the second trim panel 221 by vibration friction welding to provide the required strength and is rotatably mounted on the back door sill 21 (see Figure 3 ), the felt strip 224 is fixedly connected to the surface of the bracket 222 facing away from the second trim panel 221 to provide a connection with the tailgate structure 1 (see Figure 1 In this embodiment, the felt strip 224 is fixed to the end of the bracket 222 away from the hinge assembly 223 so as to always fit on the first trim panel 12 (see FIG. 1 ) of the tailgate structure 1 during the flipping process. Figure 1) and can slide relative to the tailgate structure 1. In this embodiment, the baffle structure 2 includes two hinge assemblies 223 spaced apart from each other, which facilitates the assembly of the tailgate product and avoids the high precision requirements of the through-axis design in the prior art. It should be understood that the baffle structure 2 composed of two hinge assemblies 223, a bracket 222 and a second trim panel 221 has been verified to meet the load requirement of 2500N in the Z direction and meet the needs of various application scenarios (picnic, camping, fishing, sitting, cycling, resting), but the design of more hinge assemblies 223 can also be used in the present utility model.

[0030] like Figure 5 As shown, the hinge assembly 223 includes a hinge 2231, a rotating shaft 2232 and a spring 2233, wherein the hinge 2231 is fixedly connected to the back door sill 21 (see Figure 3 ), the rotating shaft 2232 is rotatably inserted and installed on the hinge 2231, and the spring 2233 is limitedly installed by the rotating shaft 2232 and its two ends are hung to the hinge 2231.

[0031] like Figure 6 As shown, the rotating shaft 2232 is fixedly mounted on the bracket 222 by shape matching to define the rotation axis of the bracket 222. The bracket 222 has two hook structures protruding back to back. The middle part of the spring 2233 is hooked on the hook structure so that it can be twisted when the bracket 222 rotates relative to the hinge 2231. By hooking the spring 2233 with the hook structure, more convenient operation and non-integrated supply are achieved. In the supply state, the middle part of the spring 2233 is overlapped on the hinge 2231 in a free state, as shown in FIG. Figure 7 As shown, the client can push it into the hook structure for installation as needed. In this way, the utility model integrates the hinge function on the bracket 222 through the spring 2233, which can reduce the amount of hinges and improve the installation efficiency, achieving cost savings in quantity and man-hours. In this embodiment, the strength of the hinge assembly 223 can bear a load of 200N and a deformation of less than 1mm.

The curved surface 2222 is formed by rounding, and the curved edge is processed into a smooth curved surface 2222 to provide a smooth transition and avoid stress concentration. Preferably, the rounding radius R is between 1.5mm-3mm. In this embodiment, the depth D of the hook structure of the bracket 222 is between 3-5mm, and the width W is between 3-5mm, which can prevent the spring 2233 from falling out of the hook while facilitating the disassembly and maintenance of the spring 2233.

[0033] In the above embodiment, both ends of the spring 2233 are connected to the hinge 2231, and the middle part is connected to the hook structure of the bracket 222. In another preferred embodiment, as Fig. 9 As shown, both ends of the spring 2233' are hooked to the bracket 222', and the middle part is hooked to the hook structure of the hinge 2231'. In another preferred embodiment, as shown in FIG. Fig.10 As shown, the spring 2233" is provided by a symmetrical double torsion spring, and the opposite ends of each torsion spring are respectively hung to the bracket and the hinge.
