[0038] Example

[0039] Firstly, such as Figures 1 to 4As shown, this embodiment of the invention provides a rear seat assembly, including a seat body and a support bracket assembly. The seat body includes a seat back 1 and a seat cushion 2. The seat back 1 is rotatably connected to the seat cushion 2 through a first connecting mechanism and can be laid flat forward to be flush with the upper surface of the seat cushion 2. The support bracket assembly includes at least two support brackets. At least one support bracket is rotatably connected to the seat cushion 2 and is configured to be foldable. At least another support bracket is configured to be able to rotate backward with the folded seat body to form a flat three-dimensional structure that fits into the vehicle's storage compartment and is flush with the vehicle floor.

[0040] Specifically, such as Figures 1 to 4 As shown, in this embodiment of the invention, the support bracket assembly includes a front support bracket 4 disposed at the front end of the seat cushion 2 and a rear support bracket 5 disposed at the rear end of the seat cushion 2. The front support bracket 4 is rotatably connected to the seat cushion 2 through a second connecting mechanism and can be folded up.

[0041] In this embodiment of the invention, both the first connecting mechanism and the second connecting mechanism are hinge structures. The rotation axes of the first connecting mechanism and the second connecting mechanism are parallel and both are parallel to the vehicle floor.

[0042] In this embodiment of the invention, the rear support bracket 5 is rotatably connected to the vehicle floor via a third connecting mechanism, which is a hinge structure. The seat cushion and the rear support bracket 5 are hinged together, and under the action of external force, they rotate backward as a whole, so that the seat cushion and backrest flip backward synchronously with the rear support bracket 5 as the fulcrum. The rotation process is more stable and there is no risk of jamming.

[0043] like Figure 1 As shown, when the rear seat assembly is in normal use, the front support bracket 4 and the rear support bracket 5 are located below the seat body, and the vehicle floor is located below the front support bracket 4 and the rear support bracket 5. The front support bracket 4 and the rear support bracket 5 provide support for the seat body. The upper ends of the front support bracket 4 and the rear support bracket 5 are connected to the seat cushion 2 through the second connecting mechanism and the third connecting mechanism, respectively. The front support bracket 4 and the rear support bracket 5 are on the same straight line parallel to the X direction. The length direction of the seat body, the front support bracket 4 and the rear support bracket 5 is parallel to the Y direction. The X direction is parallel to the length direction of the vehicle body, the Y direction is parallel to the width direction of the vehicle body, and the Z direction is perpendicular to the X and Y directions. The rotation axes of the first connecting mechanism, the second connecting mechanism and the third connecting mechanism are parallel to the Y direction.

[0044] like Figures 1 to 4 As shown, in this embodiment of the invention, the front support leg 4 is folded up and placed on the top surface of the seat cushion 2.

[0045] like Figure 2 and Figure 3As shown, by rotating the seat back 1 forward, the seat back 1 is placed on the seat cushion 2, and the seat body is folded. After the seat body is folded, it can be rotated backward and the front support leg 4 can be rotated forward to form a flat three-dimensional structure. Finally, the flat three-dimensional structure is placed in the vehicle storage compartment to achieve flush with the vehicle floor. At this time, the front support leg 4 is in a folded state and is placed on the top surface of the seat cushion 2. The front support leg 4, seat cushion 2 and seat back 1 are distributed in sequence along the Z direction. The height of the front support leg 4 does not exceed the height of the top surface of the vehicle floor.

[0046] In this embodiment of the invention, the seat body is transformed into a "flat three-dimensional structure." The various components (backrest, seat cushion, and footrest) are connected by hinges to form a foldable rigid frame that perfectly fits the pre-reserved storage compartment in the vehicle body, achieving a completely flat interior floor. This significantly improves space utilization compared to existing technologies. While existing seats, even when folded down, still have backrest thickness that occupies vertical space in the trunk, this invention embeds the backrest thickness entirely into the space beneath the seat cushion. Combined with the folding and retraction of the front footrest, this reduces the overall thickness of the seat after folding, completely freeing up vertical space in the trunk. The resulting continuous flat surface can be directly used as a loading platform, meeting the storage needs of large items such as bicycles, suitcases, and camping equipment. Existing technologies, due to angled tilts or localized protrusions, cannot achieve uniform load-bearing.

[0047] like Figures 1 to 4 As shown, in this embodiment of the invention, the vehicle body storage compartment includes a first storage compartment and a second storage compartment. The first storage compartment is configured to accommodate the folded seat body, and the second storage compartment is configured to accommodate the rear support bracket 5 after it has been rotated backward. The first storage compartment and the second storage compartment are recesses formed by downward indentation from the top surface of the vehicle body floor. The first storage compartment and the second storage compartment are arranged sequentially along the X direction.

[0048] like Figures 1 to 4 As shown, in this embodiment of the invention, both the first storage slot and the second storage slot are rectangular grooves. The volume of the first storage slot is greater than the volume of the second storage slot, and the height of the first storage slot is less than the height of the second storage slot. After the rear support leg 5 is fully rotated backward, the rear support leg 5 is placed horizontally in the second storage slot, and the height of the rear support leg 5 does not exceed the height of the top surface of the vehicle floor.

[0049] Secondly, embodiments of the present invention also provide a vehicle including the electric rear seat assembly with the above-described structure. This rear seat assembly can be referred to... Figures 1 to 4 Further details will not be elaborated here. Since the vehicle of the present invention includes the rear seat assembly of the above embodiments, it possesses all the advantages of the aforementioned rear seat assembly.

[0050] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
