The traditional automobile seat structure and the adjustment function thereof are single, drivers and passengers are easy to feel waist soreness and backache after sitting for a long time, feel tired all over, and have low seating experience.
The height adjusting mechanism of the traditional automobile has a relatively complex structure, more parts and large occupied space.
Conventional car seat back frames lean down relatively to the back, because the seat cushion and back position determine the rear passenger leg space, if need increase the space and just need sacrifice automobile body length or trunk space.
The seat back structure is fixed, and for passengers with different body types and different heights, the seat back structure only considers commonalities and neglects individuality, so that different people are difficult to take into account.
Therefore, the problems are solved, and the modern automobile seat design needs to overcome the technical defects, and the specific problems are as follows:
one of the problems is to solve the problem of comfort regulation of the backrest of the current automobile seat: the rotation point of the backrest of the current automobile seat deviates from a design point, namely a theoretical design point R, so that the backrest and the upper half of a passenger cannot be completely attached in the process of adjusting the backrest, and the comfort of the seat is reduced.
The second problem is that the foot space of the passenger on the rear seat of the automobile is narrow, the current rotation point of the backrest of the automobile is that the passenger leans down backwards and is close to the floor of the automobile body, and the feet of the passenger on the rear seat cannot be put into the rotation point, so that the freedom of the foot space of the passenger on the rear seat is affected.
A third problem is to have an adjustable or motorized backrest structure, for example, the local angle of the backrest should be adjustable, so that different requirements of different people can be met.
The fourth problem is that the existing automobile seat height-adjusting mechanism is complex, large in number of parts, large in occupied space, high in manufacturing cost and troublesome in maintenance.

The limiting screw 44 is matched with the limiting hole to limit. When the double-shaft motor 41 is driven, the backrest upper connecting plate 1 rotates by a proper angle, so that the purpose of backrest sectional adjustment is achieved.
The distance between the rotating center of the motor driving device of the backrest section adjusting mechanism and the bottom edge of the backrest is 300-500 mm, and the distance is determined according to a statistical data conclusion aiming at user crowds.
The backrest rotation point is positioned at the position 100 mm-300 mm just below the point H; correspondingly, the lower backrest connecting plate 2 has an arch structure with a large circular arc. The rotation of the backrest just can be attached to the back of the passenger to move, and the requirement of the passenger on the comfort of backrest adjustment is met.
The backrest rotation point of the prior art is about 150mm behind and below the H point, so that the backrest needs to be adjusted at a very large angle, the waist of the seat is easily pressed by the backrest in the adjusting process, the fit surface of the backrest and a passenger is gradually smaller after the backrest rotates backwards, the ideal comfort is not achieved, and the backrest rotation point of the prior automobile seat is that the backrest is arranged below the backrest, the distance from the floor of an automobile body is short, the feet of the passenger cannot be put in, and the foot space of the rear passenger is affected. The backrest rotation point of the present embodiment is just at the position 100-300mm below the design point H, and in order to match the same accurate rotation after the R point is deviated, the backrest lower connecting plate 2 is designed to have a large arc arch structure to bypass the rear portion of the seat cushion frame 3 so as not to generate friction.
The scissor lift mechanism includes a push rod motor assembly 33 and an "X" shaped bracket 32, see fig. 6, in which:
the push rod motor assembly 33 comprises a motor fixing support 334 fixed on the front fixing support 34 by a fixing bolt 335, the front fixing support 34 is fixed at the front end part of the slide rail 7 on the seat, a push rod motor 331 is connected with a synchronizer 336 and fixed on the motor fixing support 334, the push rod motor 331 is connected with the synchronizer 336 at the other side through a synchronizing rod 333, the output end of the synchronizer 336 is connected with the rear end of the push rod 332, and the push rod 332 is in a screw rod structure; the synchronizer 336, the motor fixing bracket 334 and the push rod 332 are arranged in bilateral symmetry. See fig. 7.
The "X" shaped bracket 32 includes a driving strut 321 and a driven strut 322 having the same length, the driving strut is hinged by a hinge bolt 324 through a middle guide slot 326 and a middle point of the driven strut, the hinge bolt 324 is slidable in the guide slot 326, the lower end of the driving strut 321 is pinned to a front end tab of the push rod 332 by a pin connection bolt 325, and the pin connection bolt 325 is slidably engaged with a slide slot 341 of the front fixing bracket 34, see fig. 8. The upper end of the driving strut 321 is hinged to the seat-cushion side plate 31 by a connecting bolt 323, and the lower end of the driven strut 322 is hinged to a rear fixing bracket 35 fixed to the rear end portion of the upper slide rail 7 by a connecting bolt 323, see fig. 9. The upper end of the driven strut 322 is hinged to the seat side plate 31 by a pin connecting bolt 325. The driving strut 321 and the driven strut 322 are hinged using a hinge bolt 324, see fig. 10. The X-shaped brackets 32 are symmetrically arranged on both sides of the seat cushion frame 3. The structure realizes the lifting of the seat cushion of the seat by the larger stroke of the X-shaped support, before actual driving, the higher part utilizes the X-shaped support to adjust the height of the seat to reduce the height, the front end of the seat cushion gradually tends to incline, the lower part utilizes the X-shaped support to adjust the height of the seat to raise the height, the front end of the seat cushion gradually tends to sink, the inclination angle of the cushion is adjusted within the range of about 10 degrees in the adjustment of the whole X-shaped support, more humanized leg control adjustment can be provided, and the comfort angle of the seat is provided, as shown in figure 11. The specific action process is that when the push rod motor 331 is driven, the push rod 332 extends outward to push the driving strut 321 and the driven strut 322 to contract, so as to drive the seat cushion frame 3 to be lifted integrally. When the push rod motor 331 is driven in the reverse direction, the push rod 332 contracts, and pushes the driving strut 321 and the driven strut 322 to expand, thereby driving the seat cushion frame 3 to descend as a whole. See fig. 12.
In comparison, fig. 13 shows a side view of the seat frame of the present invention, and fig. 14 shows a schematic side view of a seat frame of the prior art, and it can be seen from the comparison of the drawings that the seat lifting mechanisms of the two are different in complexity.
