[0042] According to the principles of human mechanics, the sitting posture or tilt angle of the seat is adjusted by rotating the backrest assembly 1 and the seat assembly 2, the position of the seat is adjusted by sliding the side slide rail assembly 5 in the left and right directions, and the position of the seat is adjusted by sliding the lower slide rail assembly 7 in the front and back directions. In addition, according to the position of the user's legs when sitting on the seat, the leg rest assembly 8 is rotated and adjusted to support the user's legs, thereby improving the comfort of seat use.

[0043] See also Figure 3 As shown, the backrest assembly 1 includes a backrest frame 11 and a vibration absorber 12 fixedly installed with bolts to the backrest frame 11, a rotating assembly 13 is installed on the backrest frame 11, a backrest micro switch 14 is also provided on the backrest frame 11, a transmission shaft 17 is installed in the direction of the rotation axis of the backrest frame 11, a retaining spring 15 is provided on the backrest frame 11 to fix the transmission shaft 17 to prevent the shaft from moving left and right, and an angle adjustment memory motor 16 is installed on the backrest frame 11.

[0044] The angle adjustment memory motor 16 drives the electric angle adjusters on both sides, which drives the backrest frame 11 to rotate forward and backward through the transmission shaft 17. The retaining spring 15 can fix the transmission shaft 17 to prevent the shaft from moving left and right. The backrest suspension is integrally injection-molded with steel wire and plastic parts. On the one hand, it provides support, and on the other hand, some buckles and mounting holes can be arranged on the suspension to install functional accessories such as lumbar support, massage and wiring harness. A ventilation system mounting hole is reserved at the upper end of the backrest frame 11, which can be used to install a ventilation fan.

[0045] The backrest micro switch 14 is installed on the bracket and has a built-in sensor. It controls by identifying the limit point of the backrest angle limit plate. When the backrest rotates backward and hits an obstacle, the micro switch receives a signal and the backrest automatically stops electric adjustment. The seat adjustment is more intelligent and the riding safety is also improved.

[0051] One end of the front linkage piece 35 and the rear linkage piece 36 are fixed to the seat frame fixing assembly 33, and the other end is fixed to the lifting assembly 31. The linkage pieces are fixed by riveting and stepped bolts. They are all movable connections and can rotate freely. There are bushings at the fixed points to reduce friction and abnormal noise. The screw in the screw transmission assembly 34 rotates to push the lifting assembly 31 upward, and the front linkage piece 35 and the rear linkage piece 36 connected on both sides of the lifting assembly 31 move together to assist the lifting assembly 31 to be lifted upward to a certain angle, thereby realizing the control of the rotation adjustment of the basin seat assembly 2.

[0052] See also Figure 8 As shown, the slide rail anti-slip assembly 4 includes an anti-slip bracket 41 , on which two groups of tail-joint supporting steel wires 42 are fixed, and on which a connecting bracket 43 is also fixed.

[0053] The anti-drop bracket 41, the tail support wire 42 and the connecting bracket 43 effectively enhance the installation strength of the slide rail bracket and maintain the stability of the sliding installation.

[0054] See also Fig. 9As shown, the side sliding rail assembly 5 includes a side sliding front end electric rail 51, a side sliding rear end electric rail 52 is slidably connected to the side sliding front end electric rail 51, a side sliding bracket assembly 53 is fixedly installed on the side sliding rear end electric rail 52, and a module bracket assembly 54 is installed on the side sliding bracket assembly 53 by bolts.

[0055] The side sliding bracket assembly 53 and the slide rail anti-slip assembly 4 form a hook structure, which can effectively increase the strength and prevent the side sliding rail from falling out. The side sliding rear end electric rail 52 drives the seat to slide left and right, and the left and right strokes are controlled by the side sliding limit stop point. The module bracket assembly 54 can be installed with ventilation, heating, and memory modules. Some wiring harness installation holes are also reserved on the bracket to facilitate the installation of functional accessories.

[0057] The seat cushion micro switch 64 has a built-in sensor, which realizes control by identifying the limit gear point of the lower rail in the lower rail assembly 7. When the seat moves backward and hits an obstacle, the seat cushion micro switch 64 receives a signal and the seat automatically stops electric adjustment in the forward and backward directions. The seat adjustment is more intelligent and also improves riding safety.

[0058] See also Fig.12 and Fig.13 As shown, the lower slide rail assembly 7 includes an electric left slide rail 71 and an electric right slide rail 72 , and a horizontal bracket assembly 73 is installed on the electric left slide rail 71 and the electric right slide rail 72 .

[0059] The electric right slide rail 72 and the electric left slide rail 71 are started to drive the seat to move forward and backward. The electric left slide rail 71 includes an outer slide rail and an inner rail slidably connected to the outer slide rail. Considering that the force on the seat belt side is greater, the electric left slide rail 71 increases the upper and lower clamping hoop structures, and adopts the upper and lower clamping hoop inverted hook structure to increase the slide rail strength and prevent the inner rail from falling out. The upper clamping hoop is fixed to the inner rail and locked with the bracket assembly 6 through the welding bolts on the inner rail. The lower clamping hoop is fixed to the outer rail of the slide rail and is fixed by two front and rear rivets.

[0060] See also Fig.14 , Fig.15 and Fig.18As shown, the leg support assembly 8 includes a leg support mounting component 81, on which a leg support memory motor 82 is installed, the leg support mounting component 81 is rotatably connected to a leg support link a83, on which a leg support link a83 is rotatably connected to a leg support link b84, a leg support link c85 is movably connected between the leg support link b84 and the leg support mounting component 81, the leg support link c85 is rotatably connected to a leg support link d86, on which a leg support link d86 is rotatably connected to a leg support link e87, a sliding component 88 is installed on the leg support link e87, and on which a tightening wire 89 is fixed.

[0061] Leg support link a83, leg support link b84, leg support link c85, leg support link d86, and leg support link e87 form a connecting rod mechanism. The leg support memory motor 82 installed on the leg support mounting assembly 81 drives the connecting rod mechanism to realize the upward rotation of the leg support. The leg support mounting assembly 81 is fixed to the front end of the lifting assembly 31 of the seat frame assembly 3, and is locked by bolts. It can move upward with the seat basin assembly 2. The leg support connecting rods are fixed by rivets, and bushings are built into the mounting holes. The connecting rods can rotate freely around the rivets without abnormal noise. The two round tubes on the leg support mounting assembly 81 are used to increase the lateral stiffness and strength. The front end of the leg support adopts an integral sheet metal structure to increase the support and strength of the leg support. The leg support mounting assembly 81 is provided with mounting holes for installing wiring harness buckles and plastic parts.

[0062] Working principle: Driven by the memory module program, the seat can achieve the following modes:

[0063] One-touch zero gravity mode, that is, one-touch lying mode, makes it convenient for passengers to enter sleeping mode.

[0064] One-touch reset mode adjusts the seats to the designed position, making it easier for passengers to get up and also easier for rear passengers to get in.

[0065] In nap mode, the backrest angle and slide rail position are adjusted to the optimal and comfortable position through micro switch limit control.

[0066] In conversation mode or conference mode, the seats can slide from outside to inside at the same time through one-touch side sliding of the lateral slide rail. The minimum gap between the left and right seats is only 10mm, which shortens the space distance between the left and right passengers and achieves the purpose of close communication.

[0067] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
