Example 1

Please refer to fig. 1-7 for a schematic diagram of an electric foldable seat provided in the present application, which includes:

cushion assembly, cushion assembly includes: a seat support mechanism 1 and a seat cushion body 2; the seat support mechanism has a first station and a second station distributed along a first direction; the cushion body 2 is slidably arranged on the seat supporting mechanism 1; when the cushion body 2 is positioned at the first station, the cushion body 2 and the seat support mechanism 1 do not move relatively; when the cushion body 2 is positioned at the second station, the cushion body 2 moves to a maximum distance relative to the seat support mechanism 1;

a backrest assembly, the backrest assembly comprising: a backrest body 3; the backrest body 3 is rotatably connected with one end of the seat support mechanism 1; the rotation axis of the backrest body 3 extends in a second direction; the second direction is perpendicular to the first direction; the backrest body 3 has at least a third station and a fourth station when rotating around the rotation axis; when the backrest body 3 is in the third station, an initial included angle is formed between the backrest body 3 and the seat supporting mechanism 1; when the backrest body 3 is in the fourth station, the minimum included angle is formed between the backrest body 3 and the seat supporting mechanism 1;

It should be noted that the initial included angle and the minimum included angle can be set according to actual requirements; for example, the initial angle is set to 100 ° and the minimum angle is set to 10 °.

Working principle:

in the continuous research process of the automobile seat, the inventor finds that when the front seat is required to be folded to meet the moving space of the rear passengers, the backrest part (such as a waist support, an ornament, an air bag, a massage heating pad, side wings and the like) is often interfered with the seat cushion position in the seat folding process, so that the backrest part is easily damaged, and the folding stroke is smaller due to the limitation of interference, so that the space requirement of the rear passengers cannot be met;

under the background, the application provides an electric foldable seat, which is based on the following principles:

when the seat needs to be folded, the first driving mechanism drives the cushion body 2 to be switched from the first station to the second station, and at the moment, the cushion body 2 moves along the direction away from the backrest body 3, and the cushion body 2 is kept at the maximum distance under the set travel relative to the seat supporting mechanism 1; the second driving mechanism drives the backrest body 3 to be switched from the third station to the fourth station, at this time, the backrest body 3 and the seat supporting mechanism 1 form a minimum included angle, and a part of the structure of the backrest body 3 can be accommodated in the space between the cushion body 2 and the backrest body 3 or the space above the cushion body 2, so that the effective folding stroke is improved, and the activity space of rear passengers is increased, as shown in fig. 6.

When the seat needs to be taken normally, the first driving mechanism drives the cushion body 2 to be switched from the second station and restored to the first station, the cushion body 2 under the first station is positioned on the seat supporting mechanism 1, and the two mechanisms have no relative displacement, so that the riding and supporting requirements of passengers can be met; the second driving mechanism drives the backrest body 3 to be switched from the fourth station and restored to the third station, and an initial included angle is formed between the backrest body 3 and the seat supporting mechanism 1, so that the riding and leaning requirements of passengers can be met.

From this, the utility model provides an electronic collapsible seat has realized the electronic regulation of seat, and folding process reduces or has avoided the interference between back body 3 and the cushion body 2, has improved folding stroke, is favorable to increasing back row passenger's activity space, is favorable to improving passenger's travelling comfort demand.

On the basis of the above general technical concept, the present inventors, in order to further improve the folding stroke, avoid interference between the backrest body 3 and the cushion body 2, thereby:

in some embodiments, the cushion body 2 has an initial state and a retracted state;

the cushion body 2 has a first end 21 close to the backrest body 3 and a second end 22 far away from the backrest body 3, and the first end 21 is lower in the avoidance state than in the initial state, so that when the cushion body 2 is in the avoidance state, the first end 21 forms an avoidance space for avoiding the backrest body 3;

when the first driving mechanism drives the cushion body 2 to switch to the second station, the first driving mechanism drives the cushion body 2 to switch to the avoidance state.

As described above, the height of the first end 21 in the avoidance state is lower than the height of the first end in the initial state, that is, the spatial position of the cushion body 2 is adjusted, so that the relative position of the first end 21 in the avoidance state is lower, and more avoidance space exists above the first end 21, so that the backrest body 3 and the cushion body 2 are prevented from interfering with each other.

As can also be seen visually in fig. 2-3: in the initial state, as shown in fig. 2, the first end 21 is located at the upper end 131; in the retracted state, as shown in fig. 3, the first end 21 moves to the lower end 132.

In some embodiments, the seat support mechanism 1 has a rail support surface disposed obliquely, and the rail support surface has a higher end 131 proximal to the backrest body 3 and a lower end 132 distal from the backrest body 3;

a rotary support 14 is rotatably arranged at one end of the seat support mechanism 1 away from the backrest body; the rotation axis of the rotary support 14 is parallel to the second direction;

the first end of the cushion body 2 is in sliding connection with the track supporting surface; the second end 22 of the cushion body 2 is rotatably connected to the rotary support 14;

the driving end of the first driving mechanism is connected with one end of the rotary supporting piece 14, which is close to the cushion body 2;

in the initial state, as shown in fig. 2, the first end 21 of the cushion body 2 is located at the upper end 131 of the track supporting surface;

in the avoidance state, as shown in fig. 3, the first driving mechanism drives the rotation support 14 to rotate to a maximum angle about the rotation axis thereof in a direction away from the first driving mechanism, so as to drive the first end 21 of the seat cushion body 2 to move to the lower end 132 of the track supporting surface.

Further, as shown in fig. 2, when the cushion body 2 is in the initial state, it is located at the first station of the seat support mechanism; at this time, a first included angle, which is far away from the backrest body 3, of the included angles between the seat cushion body 2 and the first direction is greater than or equal to 0 ° and less than 90 °.

Further, as shown in fig. 3, when the cushion body 2 is in the avoidance state, it is located at the second station of the seat support mechanism; at this time, a second included angle, which is far away from the backrest body 3, in the included angle formed between the seat cushion body 2 and the first direction is greater than 0 degrees and less than 90 degrees; the second included angle is larger than the first included angle.
