[0026] Embodiment:

[0027] Reference Figure 1 , Figure 2、 Figure 3 、 Figure 4 and Figure 5 As shown in the drawings, a backrest flat-able rear seat structure of a car comprises a backrest plate 3 hinged on a car chassis module and a seat cushion plate 2, the seat cushion plate 2 is provided with a connecting rod 4 near one side of the backrest plate 3, one end of the connecting rod 4 is hinged on the seat cushion plate 2 and the other end is hinged on the car chassis module at a position corresponding to the side of the seat cushion plate 2 away from the backrest plate 3, so that the seat cushion plate 2 can be turned over through the connecting rod 4.

[0028] The seat cushion plate 2 is provided with seat cushion foam and the backrest plate 3 is provided with backrest foam, the seat cushion plate 2 is rotationally connected on the car chassis module and can be turned over from a horizontal state to a vertical state, thereby leaving space for the backrest to be flat, then the backrest plate 3 is folded and rotated towards the seat cushion plate 2, so that the backrest plate 3 is rotated to the space left by the seat cushion plate 2 and can be flush with the trunk.

[0029] The backrest flat-able rear seat structure of the car further comprises a support block 1, the support block 1 is fixed on the car chassis module, the support block is provided with a backrest rotating shaft 101, and the backrest plate 3 is rotationally arranged on the backrest rotating shaft 101.

[0030] The height of the rotating connection point of the backrest plate 3 and the car chassis module is increased through the support block 1, and the thickness of the backrest of the whole seat is increased due to the backrest foam arranged on the backrest plate 3, and the thickness of the backrest of the seat can be adapted through the support block 1.

[0031] The connecting rod 4 comprises an arc-shaped rod 401 and two straight rods 402, the two straight rods 402 are symmetrically arranged at two ends of the arc-shaped rod 401, the arc of the arc-shaped rod 401 is 30°-40°, and the arc-shaped rod 401 is concave towards the seat cushion plate 2.

[0032] The two straight rods 402 are convenient for connecting the connecting rod 4 with the car chassis module and the seat cushion plate 2, and the middle part is arc-shaped, which can improve the structural strength of the connecting rod 4 on one hand and can play a role of giving way due to the protruding structure on the car chassis module or other equipment installed on the car chassis module on the other hand.

[0033] The backrest flat-able rear seat structure of the car further comprises a hinge seat 6, the two ends of the connecting rod 4 are provided with hinge pieces 5 matched with the hinge seat 6, the hinge seat 6 is fixed on the car chassis module, the hinge seat 6 is in a "U" shape structure, the two side walls of the hinge seat 6 are provided with positioning holes, the hinge piece 5 comprises a "U" shaped sleeve, one end of the straight rod 402 is clamped in the sleeve, and the outer side wall of the sleeve is provided with a positioning shaft 501 matched with the positioning hole.

[0034] The hinge 5 is used for hingedly connecting the connecting rod 4 and the automobile chassis module or the seat cushion plate 2, the supporting rod is clamped in the sleeve, the sleeve side is clamped in the positioning hole of the hinge seat 6 through the bolt locking positioning, the hinge 5 can rotate around the hinge seat 6, and then the connecting rod 4 can rotate around the hinge seat 6, so that the seat cushion plate 2 is rotated.

[0035] The hinge seat 6 is symmetrically provided with a limiting table at both ends, and the side wall of the hinge 5 is provided with a limiting block 502 matched with the limiting table.

[0036] When the connecting rod 4 rotates around the hinge seat 6, the hinge 5 rotates with the connecting rod 4, and the limiting block 502 abuts against the limiting table at the end of the hinge seat 6, so that the rotation angle of the connecting rod 4 is limited, and then the rotation angle of the seat cushion plate 2 is limited.

[0037] As shown in FIG. 1, Figure 6 In use, the seat cushion foam is installed on the seat cushion plate 2, and the backrest foam is installed on the backrest plate 3, when the user wants to lay the backrest of the automobile seat, since the seat cushion plate 2 is hingedly connected with one end of the connecting rod 4, the side of the seat cushion away from the backrest can be lifted, then the connecting rod 4 is rotated to rotate around the automobile chassis module, and then the seat cushion is turned from the horizontal state to the vertical state relative to the automobile chassis module, since the backrest plate 3 is rotationally connected with the supporting block 1 on the automobile chassis module, the backrest can be rotated towards the seat cushion, and the seat cushion has been turned to the side, so that the original position of the seat cushion is left as space, and the backrest can be turned to be flush with the trunk.

[0038] In actual use, since the safety belt buckle is installed on the rear seat, when the backrest is rotated, the safety belt buckle abuts against the seat backrest, so it is necessary to rotate the safety belt buckle downward before the seat backrest is rotated, so that the safety belt buckle does not affect the rotation angle of the seat backrest.

[0039] The headrest is installed above the seat backrest, which can lengthen the length of the seat backrest, and the headrest of the automobile rear seat can abut against the seat cushion which has been rotated in some vehicles with small rear space, so it is necessary to lower the headrest, and then rotate the seat backrest, so that the headrest does not abut against the seat cushion, and the seat backrest is laid flat.

[0040] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application; the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
