[0029] Next, refer to Figures 1 - 6 to describe the foldable seat 100 according to an embodiment of the present invention. The present invention also proposes a vehicle.

[0030] In combination with Figures 1 - 3 as shown, the foldable seat 100 according to an embodiment of the present invention includes: a backrest assembly and a seat cushion assembly. The backrest assembly can be adjusted in the front-rear direction, and the seat cushion assembly can be adjusted in the up-down direction. That is, both the backrest assembly and the seat cushion assembly can be adjusted. Specifically, the backrest assembly can be adjusted in the front-rear direction, and the seat cushion assembly can be adjusted in the up-down direction.

[0031] In addition, the foldable seat 100 further includes: a controller. The controller is electrically connected to the backrest assembly and the seat cushion assembly. The controller is used to adjust the seat cushion assembly up and down to a predetermined angle when the backrest assembly is adjusted to a predetermined angle in the front-rear direction. With such a setting, when the backrest assembly is adjusted, the seat cushion assembly can be adjusted together, so that the foldable seat 100 is adjusted as a whole.

[0032] For example, when the backrest assembly is adjusted backward to a predetermined angle, the seat cushion assembly is adjusted upward to a predetermined angle, thereby realizing the overall lifting function of the seat cushion. Also, when the backrest assembly is adjusted forward to a predetermined angle, the seat cushion assembly is adjusted downward to a predetermined angle, thereby realizing the overall folding function of the seat cushion.

[0033] Thus, when the backrest assembly is adjusted forward to a predetermined angle, the seat cushion assembly is adjusted downward to a predetermined angle, thereby realizing the overall folding function of the seat cushion.

[0034] In addition, the foldable seat 100 further includes: a linkage assembly, the linkage assembly is fixed on the seat cushion assembly, and the linkage assembly is connected between the backrest assembly and the seat cushion assembly, and the linkage assembly is used to assist the up and down adjustment of the seat cushion assembly.

Among them, the horizontal tube bracket 4 extends in the left-right direction of the seat cushion assembly, that is, both ends of the horizontal tube bracket 4 are connected to both ends of the seat cushion assembly. Also, the fixed bracket 6 and the horizontal tube bracket 4 are rotatably fixed on the horizontal tube bracket 4, that is, the fixed bracket 6 can rotate relative to the horizontal tube bracket 4. Moreover, since the seat cushion assembly is fixed on the fixed bracket 6, that is, when the seat cushion assembly is adjusted up and down, the fixed bracket 6 can rotate relative to the horizontal tube bracket 4, thereby realizing the up and down adjustment of the seat cushion assembly.

[0036] Among them, the connection between the horizontal tube bracket 4 and the fixed bracket 6 is realized by bolts.

[0037] As Figure 1 and Figure 5 shown, the seat cushion assembly includes: a bottom plate 3, a seat cushion main body, and a first driving member 11. The seat cushion main body is arranged on the bottom plate 3, and the seat cushion main body is fixedly connected to the fixed bracket 6. The first driving member 11 is electrically connected to the controller, and the first driving member 11 is used to drive the seat cushion main body to be adjusted up and down. That is, the seat cushion assembly is composed of the bottom plate 3, the seat cushion main body, and the first driving member 11. Among them, the seat cushion main body is arranged above the bottom plate 3, and the first driving member 11 can drive the seat cushion main body to be adjusted up and down.

[0038] Also, the first driving member 11 can be a driving motor, and the driving motor is electrically connected to the controller. In this way, after the user issues an adjustment instruction, the driving motor can operate, thereby realizing the up and down adjustment of the seat cushion main body.

[0039] Moreover, the linkage assembly is fixed on the bottom plate 3, that is, by setting the bottom plate 3, an installation point can be provided for the linkage assembly.

[0040] In addition, the fixing bracket 6 includes a side plate and two end plates. The two end plates are arranged on the upper and lower sides of the side plate, and a fitting groove can be formed between the side plate and the two end plates.

That is to say, the first linkage piece 9 and the second linkage piece 8 are arranged on the upper and lower sides of the first connecting piece. The first linkage piece 9 and the second linkage piece 8 can be folded and unfolded. That is, the end of the first linkage piece 9 away from the second linkage piece 8 and the end of the second linkage piece 8 away from the first linkage piece 9 can move away from or close to each other, so that the seat cushion body and the bottom plate 3 move closer to or away from each other.

[0045] Among them, when the first linkage 10 is in the initial position, the first linkage piece 9 and the second linkage piece 8 are on the same straight line. At this time, the distance between the seat cushion body and the bottom plate 3 is the farthest. And when the first linkage 10 moves in the front-rear direction, the first linkage piece 9 and the second linkage piece 8 are folded with each other. At this time, the distance between the seat cushion body and the bottom plate 3 decreases.

[0046] Furthermore, the first driving member 11 is fixed to the seat cushion body 7 through a mounting bracket 12. A motor lead screw 14 and a motor nut 13 are also connected to the first driving member 11, and the motor nut 13 is fixedly welded to the first linkage piece 9.
