Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figures 1 to 4This utility model provides a technical solution: a multi-functional adjustable seat, including a seat cushion assembly, a backrest, and a folding backrest; the seat cushion assembly consists of a support frame 14 and a seat cushion frame 7, which are connected by bolts; the seat cushion frame 7 has two side connecting plates 17 on both the front and rear sides, and two oppositely distributed round tubes 18 in the middle of the seat cushion frame 7; the backrest includes an upper shoulder frame 1 and an upper waist frame 4, which are connected by an upper folding locking assembly 2 and an upper motor 3; the backrest is connected to the seat cushion frame 7 by a middle and rear folding locking assembly 6 and a middle and rear motor 5; the folding backrest includes a lower waist frame 10 and a lower shoulder frame 13, which are connected by a lower folding locking assembly 11 and a lower motor 12; the folding backrest is connected to the seat cushion frame 7 by a middle and front folding locking assembly 8 and a middle and front motor 9.

[0028] In this embodiment, refer to Figure 1 At this time, the seat is in the following state: the upper shoulder frame 1 and the upper waist frame 4 in the backrest are unfolded relative to each other, the backrest and the seat cushion frame 7 are unfolded relative to each other, the folding backrest and the seat cushion frame 7 are folded relative to each other, and the lower waist frame 10 and the lower shoulder frame 13 in the folding backrest are folded relative to each other. At this time, the seat is in the forward-facing sitting position.

[0029] See Figure 4The seat cushion frame 7 has two side connecting plates 17 on both the front and rear sides. Two oppositely distributed round tubes 18 are also located in the middle of the seat cushion frame 7. The round tubes 18 are welded to the seat cushion frame 7, and the side connecting plates 17 are connected to the seat cushion frame 7 by bolts. The upper folding locking assembly 2, the middle rear folding locking assembly 6, the middle front folding locking assembly 8, and the lower folding locking assembly 11 have the same structure, each consisting of two angle adjusters 15 and a spline shaft 16. The spline shaft 16 is driven by a motor. When the upper shoulder frame 1 and upper waist frame 4 in the backrest need to be folded relative to each other, the upper motor 3 is started to rotate clockwise, driving the spline shaft 16 in the upper folding locking assembly 2 to rotate clockwise. The clockwise rotation of the spline shaft 16 drives the angle adjusters 15 in the upper folding locking assembly 2 to rotate clockwise. When the spline shaft 16 in the upper folding locking assembly 2 rotates 180° clockwise, the upper shoulder frame 1 and upper waist frame 4 in the backrest are folded relative to each other. When the upper shoulder frame 1 and upper waist frame 4 in the backrest need to be unfolded relative to each other, the upper motor 3 is started in reverse to drive the spline shaft 16 in the upper folding locking assembly 2 to rotate 180° in reverse. When the backrest needs to be folded relative to the seat cushion frame 7, the middle and rear motor 5 is started in the forward direction to drive the spline shaft 16 in the middle and rear folding locking assembly 6 to rotate in the forward direction. The forward rotation of the spline shaft 16 drives the angle adjuster 15 in the middle and rear folding locking assembly 6 to rotate in the forward direction. After the spline shaft 16 in the middle and rear folding locking assembly 6 rotates 180° in the forward direction, the backrest and seat cushion frame 7 are folded relative to each other. Conversely, when the backrest and seat cushion frame 7 need to be unfolded relative to each other, the middle and rear motor 5 is started in reverse to drive the spline shaft 16 in the middle and rear folding locking assembly 6 to rotate 180° in reverse. The principle for adjusting the relative position of the folded backrest and seat cushion frame 7, and the relative position of the lower waist frame 10 and lower shoulder frame 13 in the folded backrest, is the same as the above working principle.

[0030] When the folding backrest and seat cushion frame 7 are unfolded relative to each other, the lower back frame 10 and lower shoulder frame 13 in the folding backrest are unfolded relative to each other, the upper shoulder frame 1 and upper back frame 4 in the backrest are folded relative to each other, and the backrest and seat cushion frame 7 are folded relative to each other. At this time, the seat is in the reverse-facing position. The above operations can realize the switching between forward and reverse-facing positions of the seat.

[0031] For further details, please refer to Figure 3 The upper folding locking assembly 2, the middle rear folding locking assembly 6, the middle front folding locking assembly 8, and the lower folding locking assembly 11 are all composed of two angle adjusters 15 and a spline shaft 16.

[0032] Furthermore, the upper motor 3 can drive the upper folding locking assembly 2 to rotate 180°, the middle and rear motor 5 can drive the middle and rear folding locking assembly 6 to rotate 180°, the lower motor 12 can drive the lower folding locking assembly 11 to rotate 180°, and the middle and front motor 9 can drive the middle and front folding locking assembly 8 to rotate 180°.

[0033] Furthermore, the spline shaft 16 is driven by a motor to rotate forward or in reverse.

[0034] Furthermore, the forward rotation of the spline shaft 16 drives the angle adjuster 15 to rotate forward, and the reverse rotation of the spline shaft 16 drives the angle adjuster 15 to rotate in reverse.

[0035] In this embodiment, taking the adjustment of the upper folding locking assembly 2 as an example: when the upper shoulder frame 1 and upper waist frame 4 in the backrest need to be folded relative to each other, the upper motor 3 is started to rotate forward, driving the spline shaft 16 in the upper folding locking assembly 2 to rotate forward. The rotation of the spline shaft 16 drives the angle adjuster 15 in the upper folding locking assembly 2 to rotate forward. When the spline shaft 16 in the upper folding locking assembly 2 rotates 180° forward, the upper shoulder frame 1 and upper waist frame 4 in the backrest are folded relative to each other. Conversely, when the upper shoulder frame 1 and upper waist frame 4 in the backrest need to be unfolded relative to each other, the upper motor 3 is started to rotate in reverse, driving the spline shaft 16 in the upper folding locking assembly 2 to rotate in reverse 180°. The working principle of the other middle and rear folding locking assembly 6, middle and front folding locking assembly 8, and lower folding locking assembly 11 is the same.

[0036] For further details, please refer to Figure 3 The center hole of the angle adjuster 15 matches the shaft diameter of the spline shaft 16.

[0037] In this embodiment, the center hole of the angle adjuster 15 is matched with the shaft diameter of the spline shaft 16, so that the rotation of the spline shaft 16 can drive the angle adjuster 15 to rotate.

[0038] In another embodiment, the front seat: when the upper shoulder frame 1 and upper waist frame 4 in the backrest of the upper motor 3 are unfolded relative to each other, and the backrest of the middle and rear motor 5 is parallel to the seat cushion frame 7, the backrest of the front seat, the seat cushion frame 7 of the front seat and the seat cushion of the rear seat are at the same level. In this way, the front seat and the rear seat cooperate to realize the "big bed" scenario of the seats.

[0039] The working principle and usage process of this utility model are as follows: (See attached document) Figure 1At this point, the seat is in the following positions: the upper shoulder frame 1 and upper lumbar frame 4 in the backrest are unfolded relative to each other, the backrest and seat cushion frame 7 are unfolded relative to each other, the folding backrest and seat cushion frame 7 are folded relative to each other, and the lower lumbar frame 10 and lower shoulder frame 13 in the folding backrest are folded relative to each other. The seat is in a forward-facing position. When the folding backrest and seat cushion frame 7 are unfolded relative to each other, the lower lumbar frame 10 and lower shoulder frame 13 in the folding backrest are unfolded relative to each other, and the upper shoulder frame 1 and upper lumbar frame 4 in the backrest are folded relative to each other... The backrest and seat cushion frame 7 are folded in opposite positions, and the seat is in a reverse-facing position. The above operation can realize the switching between forward and reverse seating. Front seats: When the upper shoulder frame 1 and upper waist frame 4 in the backrest of the upper motor 3 are unfolded in opposite positions, and the backrest of the middle and rear motor 5 is parallel to the seat cushion frame 7, the backrest of the front seat, the seat cushion frame 7 of the front seat and the seat cushion of the rear seat are at the same level. In this way, the front seat and the rear seat work together to realize the "big bed" scene of the seats.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
