In the adjusting structure shown in fig. 1, the seat body is adjusted up and down by the motor through the toothed plate 200 at the rear end of the supporting frame 100, if the adjusting structure shown in fig. 1 is adopted, the inclination angle of the supporting frame 100 is kept in the range of 8 ° to 9 ° except for the height adjustment of the seat body in the whole adjusting stroke, as shown in fig. 2, the inclination angle of the supporting frame is smaller, basically maintained unchanged, and the riding comfort of passengers is poor. In addition, in the adjusting structure shown in fig. 1, since the toothed plate is arranged at the rear end of the supporting framework, the rear connecting beam is higher in the Z direction (i.e., the height direction), so that the angle adjuster is arranged to be higher, the backrest rotating shaft of the seat is higher, and when the backrest rotates backwards, the problem that the lower end of the backrest foams and the seat cushion have a larger step difference exists, so that the riding comfort can be further influenced. In order to further improve the function of the adjusting structure, the following technical scheme is provided in the embodiment of the invention.
An adjustment structure 60 of a seat according to an embodiment of the present invention will be described in detail with reference to fig. 3 to 6.
The adjusting structure 60 of the seat according to the embodiment of the first aspect of the present invention includes: a base 70, an adjustment assembly and a support frame 18, the adjustment assembly being located between the base 70 and the support frame 18, the support frame 18 being capable of carrying the seat body 50 of the seat.
The adjustment assembly includes: the device comprises a first front connecting bracket, a second front connecting bracket 5, a motor assembly, a height adjusting plate 8, a synchronizing rod 19, a first rear connecting bracket 1 and a second rear connecting bracket 2.
As shown in fig. 3 and 4, wherein both ends of the first front connection bracket are rotatably connected to the support frame 18 and the base 70, respectively; the second front connecting brackets 5 and the first front connecting brackets are distributed in parallel along a preset direction; one end of the second front connecting bracket 5 is rotatably connected to the supporting framework 18; the motor assembly comprises a lifting motor 6 and a motor bracket 7, the lifting motor 6 is mounted on the motor bracket 7, and the motor bracket 7 is mounted on the base 70 and is adjacent to the second front connecting bracket 5; a first end of the height adjustment plate 8 is rotatably connected with the other end of the second front connecting bracket, a second end of the height adjustment plate 8 is connected with the output end of the lifting motor 6, and a part of the height adjustment plate 8 between the first end and the second end is rotatably connected to the base 70; the second end is opposite to the first end, and the lifting motor 6 can drive the second front connecting bracket 5 to move along the direction perpendicular to the preset direction through the high adjusting plate 8; two ends of the synchronizing rod 19 are respectively arranged on the first front connecting bracket and the high adjusting plate 8; the two ends of the first rear connecting bracket 1 are respectively and rotatably connected to the supporting framework 18 and the base, and the first rear connecting bracket 1 and the first front connecting bracket are distributed in parallel in a direction perpendicular to the preset direction; the two ends of the second rear connecting bracket 2 are respectively rotatably connected to the supporting framework 18 and the base, and are distributed in parallel with the first rear connecting bracket 1 in the preset direction.
In the embodiment of the present invention, the "rotatable" connection manner may be the connection between the shaft member and the through hole, but is not limited thereto.
As shown in fig. 6, the seat body 50 supported by the support frame 18 generally includes a seat cushion 51 and a seatback 52, but is not limited thereto. Relatively, the seat cushion 51 is in the front and the backrest 52 is located behind the seat cushion.
As shown in fig. 3, 4 and 6, the support frame 18 may be generally basin-shaped, also referred to as a bowl.
The preset direction refers to a direction perpendicular to the front-rear direction, i.e., the left-right direction of the seat.
In the motor assembly, the lifting motor 6 is fixed on the motor bracket 7, and the lifting motor 6 is used for providing driving force and drives the supporting framework 18 to move through the high adjusting plate 8 and the second front connecting bracket 5.
The first end of the high-speed adjusting plate 8 is connected with the second front connecting bracket 5 which drives the supporting framework 18 to move, the second end of the high-speed adjusting plate 8 is connected with the lifting motor 6, a through hole is formed in the middle of the high-speed adjusting plate 8, and the high-speed adjusting plate 8 is rotatably installed on the base by means of connecting pieces such as step bolts 9 and the like penetrating through the through hole and through holes in the base. The mounting mode enables the first end and the second end of the high adjusting plate 8 to form a seesaw type movement structure, and the second front connecting bracket 5 is driven to move by the high adjusting plate 8, so that the second front connecting bracket 5 drives the supporting framework 18 to move.
Without limitation, the first end of the height adjustment plate 8 may refer to the rear end of the height adjustment plate 8, and the second end of the height adjustment plate 8 may refer to the front end of the height adjustment plate 8.
The synchronizing rod 19 is used for transmitting the driving force received by the high adjusting plate 8 to the first front connecting bracket, so that the first front connecting bracket and the second front connecting bracket 5 can synchronously drive the supporting framework 18 to move. In the process that the lifting motor 6 drives the second front connecting bracket 5 to move through the height adjusting plate 8, the included angle of the second front connecting bracket 5 relative to the base 70 can be changed, so that the height of the second front connecting bracket driving the supporting framework 18 can be changed. Because the first rear connecting bracket 1 and the second rear connecting bracket 2 can rotate relative to the base 70 and the supporting framework 18, the supporting framework 18 can also incline in the rear direction while generating the height change, and the change of the inclination angle of the seat is realized.
The height adjusting plate 8 and the motor component are arranged in front of the base 70 adjacent to the second front connecting bracket 5, so that occupation of space behind the motor component and the height adjusting plate 8 on the adjusting structure is reduced, more movable space can be provided behind the adjusting structure, and the adjusting angle of the adjusting component on the supporting framework 18 in the adjusting structure is increased. For the seat, the increase in the adjustable angle of the support frame 18, i.e., the increase in the seat back adjustable tilt angle, also achieves a reduction in the back foam and cushion foam step difference when the seat back rotates backward, improving the comfort of the occupant sitting in the seat.
The adjustment structure of the embodiment of the present invention can increase the inclination angle of the support frame 18 to 21 ° or more. In some examples, the support frame 18 may be inclined at an angle of up to 21.7 °.
The adjusting structure can realize zero gravity sitting posture when applied to a vehicle.
The motor assembly is adjusted to the lower front part of the supporting framework 18, and can be narrowed in a vehicle in the Y direction (generally referred to as the left-right direction) of a side plate at the rear of the seat, and the distance between the seat and the B column of the vehicle is increased so as to be beneficial to the arrangement of the lower end plates of the double pre-tightening installation belt.
Furthermore, the motor assembly is disposed at the front lower portion of the support frame 18, which makes it easier to dispose the seat body 50, which is advantageous in reducing the influence on the MTM of the seat. When the novel multifunctional seat is applied to a seat, the seat can be applied to two rows, and the rear end toothed plate is omitted, so that the transverse space inside the seat framework is increased, and ISOFIX arrangement is facilitated.
According to some alternative embodiments, the supporting framework 18 has at least a first position and a second position with respect to the base 70, driven by the lifting motor 6; wherein the rearward inclination of the support frame 18 in the second position is greater than the rearward inclination of the support frame 18 in the first position.
The supporting framework 18 is located at the first position, the first end of the high adjusting plate 8 is in contact with the base 70, and the rear sides of the first rear connecting bracket 1 and the second rear connecting bracket 2 are separated from the base; the supporting frame 18 is located at the second position, the second end of the height adjusting plate 8 is in contact with the base, and the rear sides of the first rear connecting bracket 1 and the second rear connecting bracket 2 are both in contact with the base 70.
Fig. 3 and 6 schematically illustrate the attitude of the adjustment structure when the support frame 18 is in the second position. At this time, the rearward inclination angle of the support frame 18 and the seat body 50 is maximized.
In the process of driving the high adjusting plate 8 to rotate relative to the base 70 by the lifting motor 6, the high adjusting plate 8 can drive the second front connecting bracket 5 to move downwards by utilizing a rocker structure formed by the high adjusting plate 8 and the base 70 until the first end of the high adjusting plate 8 is contacted with the base 70. Alternatively, the height adjustment plate 8 may move the second front connection bracket 5 upward until the second end of the height adjustment plate 8 contacts the base 70.
The first position may refer to an initial position of the support frame 18, i.e. the position of the support frame 18 in the initial state of the adjustment structure when the lifting motor 6 is not driven. In the first position, the rearward inclination of the support frame 18 may be, without limitation, 12.9 °.
According to some alternative embodiments, the rearward inclination of the support frame 18 in the second position is greater than or equal to 21 °.

As shown in fig. 3 and 4, the connection of the fixed bracket 12 and the base 70 also forms a rocker structure.
The fine adjustment driving member includes, without limitation, a fine adjustment motor 10 and a screw structure connected to a rotation shaft of the fine adjustment motor 10 and capable of converting a rotation motion of the rotation shaft into a linear motion. At this time, fine adjustment of the support frame 18 can be achieved by the back-and-forth movement of the fine adjustment drive.
According to some alternative embodiments, the second end of the height adjustment plate 8 has a through hole and internal teeth distributed along the wall of the through hole, and the output end of the lifting motor 6 comprises an output gear, and the internal teeth are meshed with the output gear.
Compared with external gear meshing transmission, the embodiment of the invention adopts internal gear meshing transmission, so that the space occupation can be smaller, and the structure is more compact.
According to some alternative embodiments, the adjustment assembly further comprises: a front connecting beam 4 rotatably mounted on the front end of the supporting frame 18, both ends of the front connecting beam 4 being connected to the first front connecting bracket and the second front connecting bracket 5, respectively; and a rear connection cross member 3 rotatably installed on a rear end of the support frame 18, both ends of the rear connection cross member 3 being connected with the first rear connection bracket 1 and the second rear connection bracket 2, respectively.
