The invention relates to a use method of a seat capable of adjusting sitting and lying states in a railway vehicle business area, which comprises the following steps: when the headrest framework is adjusted, the headrest side framework is manually bent towards the headrest middle framework, and under the action of the damping hinge, the headrest side framework and the headrest middle framework can keep any angle; in addition, the headrest framework is manually pushed upwards, the damping guide rail moves upwards relative to the sliding block, and the linear sliding groove moves upwards relative to the limiting block, so that the headrest framework is adjusted in the up-and-down direction, and finally the headrest framework is adjusted.
When the seat is electrically adjusted in sitting posture, semi-lying state and full-lying state, and the seat is adjusted from the sitting posture to the semi-lying state and the full-lying state, the seat translation motor drives the gear rotating shaft to rotate, the gear rotating shaft drives the gear to rotate, so that the rack is driven to move forwards, and the rack drives the supporting plate to move forwards along the three-level sliding rail, so that the cushion framework is driven to move forwards; the cushion skeleton passes through the gyro wheel and moves along curve spout, carries out the location of cushion skeleton. At the moment, the cushion framework drives the backrest framework to move through the connecting rod II, and the backrest framework moves downwards through the connecting rod I. When the roller moves forwards to a turning point where the curve chute descends to ascend, the seat translation motor stops running, and the seat is in a semi-lying state; the moving speed of the cushion framework and the backrest framework is stable in the process. When the roller continues to move forwards to the foremost end of the curved sliding groove from the turning point of descending to ascending from the curved sliding groove, the seat translation motor stops running, and the seat is in a full-lying state; in the process, the rear end of the cushion framework gradually rises, the backrest framework continues to fall, the speed and acceleration changes in the direction perpendicular to the three-level slide rail occur at the turning point of the roller from the falling to the rising of the curve chute, and the roller maintains constant jerk value in the moving process by setting the rising structure at the front part of the curve chute.
When the leg support framework is adjusted, the leg support motor operates to drive the ejector rod to stretch back and forth, when the ejector rod extends forwards, a forward force is applied to the leg support framework, and the leg support framework rotates upwards to a position parallel to the cushion framework through the leg support rotating hook piece. When the ejector rod retracts backwards, backward force is applied to the leg support framework, and the leg support framework rotates downwards to a position vertical to the seat cushion framework through the leg support rotating hook piece.
When the electric adjustment of the seat has a problem, pulling the steel wire rope II to pull the pin II out of the seat translation motor, so that the seat translation motor stops running; pulling the steel wire rope I to pull the pin I out of the leg support motor, so that the leg support motor stops running; then, the sitting posture, the half-lying state and the full-lying state of the cushion framework and the backrest framework are adjusted by manually moving the cushion framework; the leg support framework is adjusted by manually rotating the leg support framework.
By adopting the technical scheme, the invention has the following beneficial effects:
(1) the seat cushion frame is driven by the seat translation motor to move back and forth, the seat cushion frame moves back and forth through the three-level slide rails and the racks, the three-level slide rails occupy small space, and the distance for the seat cushion frame to move back and forth is long; the shape of the sliding groove is arranged, and in the ascending section of the roller, the jerk value of the roller in the direction vertical to the three-level slide rail is constant, so that the discomfort of passengers caused by the obvious acceleration of the speed of the backrest framework when the seat is adjusted from a half-lying state to a full-lying state is avoided; and the rollers simultaneously ascend when moving forwards along the sliding grooves, so that the rear end of the cushion framework is lifted when the seat is in a full-lying state, the angle of the cushion framework in the sitting posture, the half-lying state and the full-lying state is more comfortable, and the comfort degree of the seat and the seat in the adjusting process is improved.
(2) When realizing the cushion skeleton back-and-forth movement through connecting rod I and connecting rod II, drive back skeleton downstream, and the back skeleton moves forward when moving down for in the seat state adjustment process, back skeleton is vertical downstream basically, does not occupy the seat rear side space, and occupation space is little.
(3) The leg support framework is adjusted through the leg support motor, the structure is simple, and the operation is convenient.
(4) When the problem occurs in the electric adjustment of the seat, the pin is pulled out through the steel wire rope, so that the leg support motor and the seat translation motor stop running, the leg support framework, the cushion framework and the backrest framework are manually adjusted, the sitting posture, the semi-lying state and the full-lying state of the seat are adjusted, and the electric adjustment device is simple to operate and convenient to use; and the steel wire rope is fixed and protected through the supporting pad or the rope sleeve, so that the operation of other structures of the seat is prevented from being influenced.
(5) The adjustment of the headrest framework is realized through the damping hinge, the damping guide rail, the linear sliding groove, the sliding block and the limiting block, and the comfort level of the headrest part of the seat is improved.
