Description

Automobile seat with height-lifting seat basin at rear end

Technical Field

The utility model relates to a car seat, concretely relates to but car seat of seat basin rear end height lifting.

Background

The comfort of the automobile seat plays a role in playing a role in the driving experience of a user. Nowadays, both automobile manufacturers and consumer terminals place more stringent demands on the comfort of the seat. In order to facilitate the rest of the passengers or provide richer sitting posture modes, most seats have a flat-down function, namely: the backrest is laid back to a horizontal or near horizontal position.

In the existing automobile seat structure, because the rear end of the seat supporting plane is slightly inclined downwards, and the rotation center line of the backrest angle adjuster is higher than the seat supporting plane, after the backrest is leveled, a height difference exists between the seat supporting plane and the backrest supporting plane, the height difference can cause the rear end of the hip of a user to lack of support, even in an obvious suspension state, and the comfort experience of the user in lying is poor.

Preferably, the front end of the seat basin is rotatably mounted on the seat frame through a rotating shaft.

Preferably, the driving sheet is provided with a first mounting point, a second mounting point and a third mounting point which are distributed in a triangular mode, the position, connected with the seat frame in a rotating mode, of the driving sheet is located at the first mounting point, the supporting shaft is arranged at the second mounting point, and the output power of the power device acts on the third mounting point of the driving sheet.

Preferably, the power device comprises a screw rod and a motor assembly for driving the screw rod to move along the axial direction of the screw rod, wherein one end of the screw rod is rotatably connected to the driving sheet.

Preferably, the strip-shaped holes are arranged in a horizontal direction.

Compared with the prior art, the beneficial effects of the utility model are that:

adopt the utility model provides a but car seat of seat basin rear end height lifting, after the back is fallen flat completely, power device drives the driving plate and rotates, and the back shaft of driving plate promotes seat basin rear end upward movement to compensate the back and fall the difference in height between back seat supporting plane and the back supporting plane, make seat supporting plane and back supporting plane be in the coplanar almost, the user lies flat and has better travelling comfort.

Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

As shown in fig. 1, a car seat, this seat includes seat frame 1, the rear end of seat frame 1 rotates installs back 2, be provided with a seat basin 3 in the seat frame 1, 3 front ends of seat basin rotate with seat frame 1 through rotation axis 6 and are connected, combine figure 2 can find out, 1 rear end of seat frame rotates installs driving plate 4, the last back shaft 4a that has set firmly of driving plate 4, 3 rear ends of seat basin are equipped with bar hole 3a, the last back shaft 4a slip assembly of driving plate 4 is in this bar hole 3a, power device 5 is still installed at 1 middle part of seat frame, power device 5 can drive above-mentioned driving plate 4 and rotate.

Based on the above structural arrangement of car seat, the theory of operation that high lifting is realized to 3 rear ends of seat basin does: referring to fig. 1 to 4, the power device 5 pushes the driving plate 4 to rotate, and the supporting shaft 4a moves towards the upper right direction along with the rotation of the driving plate 4, so as to drive the seat pan 3 to rotate counterclockwise by using the rotating shaft 6 as a rotation center line, and the rear end of the seat pan 3 lifts upwards along with the rotation center line, when the backrest 2 is completely flattened, the lifting amount of the rear end of the seat pan 3 can make up the height difference between the seat supporting plane and the backrest supporting plane, so that the seat supporting plane and the backrest supporting plane of the car seat are almost in the same plane, and the comfort of the user in lying can be significantly improved.

Referring to fig. 2, in the present embodiment, the driving plate 4 is a triangular plate-shaped structure, and three corner positions thereof are respectively provided with a first mounting point a, a second mounting point b and a third mounting point c, the driving plate 4 is rotatably connected with the seat frame 1 through a rotating pin 7 at the first mounting point a, the supporting shaft 4a is fixedly arranged at the second mounting point b, and the third mounting point c is used for connecting the power device 5. By adopting the design, the rotation of the driving sheet 4 can be better converted into the lifting movement at the rear end of the seat basin 3.

In the embodiment, the power device 5 is composed of a screw rod 5a and a motor component 5b for driving the screw rod 5a to move, and one end of the screw rod 5a is rotatably connected to a third mounting point c of the driving sheet 4. In the process that the power device 5 pushes the driving sheet 4 to rotate, the screw rod 5a performs compound motion, including axial movement of the screw rod 5a and rotary motion of the screw rod 5a around a rotor of the motor component 5b, wherein the rotary motion of the screw rod 5a around the rotor of the motor component 5b can absorb the up-and-down displacement of the screw rod 5a, and motion interference is avoided. The motor assembly 5b drives the screw rod 5a to move is the prior art, and the working principle thereof is not further described herein.

As shown in fig. 2, the strip-shaped holes 3a are arranged along the horizontal direction, so as to better absorb the displacement of the supporting shaft 4a along the horizontal direction and avoid movement interference.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
