Technical Field
[0001] The utility model belongs to the technical field of seats, and particularly relates to a Background Art
[0002] In order to improve the riding comfort of vehicle seats, multiple connections between various parts of the seat frame are designed as adjustable connections, so as to facilitate the adjustment of the seat posture, thereby providing sufficient and appropriate support for various parts of the body. Based on this, the concept of a zero-gravity seat is proposed. The zero-gravity seat provides a more ergonomic and healthier riding posture for passengers, and is mostly applicable to the co-pilot and rear seats. The zero-gravity seat posture can help reduce the pressure on the spine, relax the back muscles, reduce the pressure on the heart, and at the same time promote blood circulation, enhance the riding comfort of the vehicle, and better protect the health of the occupants.
[0003] The seats inside the vehicle include a seat body and a backrest connected to the seat body. Currently, the common seat adjustment mechanisms on the market generally adjust the front and rear positions of the seat in the vehicle body and the angle of the backrest, while the adjustment of the seat body angle is less. Therefore, how to provide a solution to adjust the angle of the seat body is still a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

The two sides of the lower rear part of the upper seat frame assembly are respectively hinged to the rear parts of the rainbow bridge assemblies arranged on both sides. The front parts of the two rainbow bridge assemblies on both sides are hinged with a front lift reinforcement tube. A first rocker arm is fixed on one side of the front lift reinforcement tube, and second rocker arms are respectively fixed on both sides of the front lift reinforcement tube. A first lead screw motor for driving the lead screw to rotate is hinged to the middle of the rainbow bridge assembly. A nut threadedly connected to the lead screw is hinged to the first rocker arm. The outer ends of the second rocker arms on both sides of the front lift reinforcement tube are respectively hinged to one ends of the two connecting rods on both sides. The other ends of the two connecting rods on both sides are respectively hinged to the two sides of the lower front part of the upper seat frame assembly. The rotation of the lead screw driven by the first lead screw motor drives the nut to move on the lead screw, the rotation of the front lift reinforcement tube, the first rocker arm and the second rocker arms, the swing and angle adjustment of the upper seat frame assembly in sequence.
[0007] As a further optimization of the above technical solution, the lower parts of the rainbow bridge assemblies on both sides are fixedly mounted on sliders, and the sliders are slidably arranged on longitudinal and parallel slide rails on both sides. The motor drives the sliders to slide back and forth on the slide rails to achieve the front-back adjustment of the seat.
[0008] As a further optimization of the above technical solution, the slide rails on both sides are connected by a cross bridge bracket arranged horizontally in the middle.
[0009] As a further optimization of the above technical solution, the cross section of the slide rail is provided with axial strip grooves on the inner surfaces of the two side walls of the U-shaped body, and the cross section of the slider is provided with outward-turning edges at the lower parts of the two side walls of the inverted U-shaped body to form axial slide strips, and the slide strips are arranged in the strip grooves to achieve the sliding fit between the slide rail and the slider.
[0010] As a further optimization of the above technical solution, mounting holes are respectively arranged on both sides of the lower bottom of the slide rail, and annular washers coaxially mounted with the mounting holes are arranged on the lower surface of the slide rail, and the inner diameter of the mounting hole is less than or equal to the inner diameter of the annular washer.
[0011] As a further optimization of the above technical solution, the rainbow bridge assembly includes a left rainbow bridge and a right rainbow bridge, and the left rainbow bridge and the right rainbow bridge are connected by a motor support pipe arranged horizontally in the middle and a front lift strengthening pipe arranged horizontally at the front side. A motor bracket is fixed on the motor support pipe, and the first lead screw motor is hinged on the motor bracket.
[0012] As a further optimization of the above technical solution, the front lift strengthening pipe is a hollow tubular shaft.
[0013] As a further optimization of the above technical solution, a leg rest driven by a second lead screw motor for telescoping is connected to the front part of the upper seat frame assembly. The leg rest is connected to the seat frame by bolts, and the length, height and angle of the leg rest are adjusted by the motor on the leg rest.
[0014] As a further optimization of the above technical solution, the upper seat frame assembly is composed of a front cross pipe at the front end, a rear cross pipe at the rear end, left seat frame side plates and right seat frame side plates symmetrically distributed on both sides to form a rectangular frame. The rear parts of the left seat frame side plates and the right seat frame side plates are respectively hinged to the rear part of the rainbow bridge assembly, and the front parts of the left seat frame side plates and the right seat frame side plates are respectively hinged to the other ends of the connecting rods on both sides.
[0015] As a further optimization of the above technical solution, a seat basin is welded to the front parts of the front cross pipe, the left seat frame side plate and the right seat frame side plate, which is convenient for installing a seat cushion.
[0016] When the inclination angle needs to be adjusted, the lead screw motor drives the nut to move towards the direction close to the lead screw motor, thereby driving the front lifting reinforcement pipe to rotate clockwise, and the front part of the seat is lifted; the lead screw motor drives the nut to move away from the lead screw motor, thereby driving the front lifting reinforcement pipe to rotate counterclockwise, and the front part of the seat is lowered, realizing the inclination adjustment of the seat. The leg rest is connected to the seat frame by bolts, and the angle of the leg rest is adjusted by the motor on the leg rest.
[0017] With the above structure, the front lifting cross pipe assembly is driven by the lead screw motor, and then the front end of the seat body is lifted or lowered to realize the inclination adjustment of the seat cushion. The lower end of the backrest is connected to the rear side of the upper seat frame assembly by bolts. In addition to realizing the reclining angle adjustment of the backrest through the angle adjuster, the reclining angle of the backrest also meets the adjustment requirements simultaneously with the adjustment of the seat cushion inclination.
[0018] The utility model provides a more ergonomic and healthier sitting posture for passengers by adjusting the inclination angles of the seat cushion and the backrest. This seat is also called a zero-gravity seat and is mostly applicable to the co-pilot and rear seats. The zero-gravity seat posture can help reduce the pressure on the spine, relax the back muscles, relieve the pressure on the heart, and at the same time promote blood circulation, enhance the riding comfort of the car, and better protect the health of the occupants.
