The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Air compressor 6 is connected with air processor 7, and air processor 7 is connected with energy storage 8, and energy storage 8 exits are connected to outlet pressure sensor 9; Energy storage 8 is connected with cylinder 15 admission ports through electromagnetic valve A10, check valve 11, flow regulating valve 12; Cylinder 15 inflow points are connected to air inlet pressure sensor 14; Piston rod 17 contacts with piston rod guide rail 19 through piston rod sphero-joint 18; Cylinder 15 air extractor ducts are connected with air processor 7 through electromagnetic valve B13;
On seat 1 backrest, pressure sensor is housed, with human body, whether contacts with back of seat; Brake pedal sensor is housed on brake pedal, to detect, whether brakes;
Door controller 4 adopts and gate control, and according to internal circuit configuration, the pressure signal of taking pressure sensor 2 is 1 input while being zero, otherwise is 0 input; While being zero, be 0 input during brake pedal sensor 3 brakeless signal, otherwise be 1 input, while only having two inputs to be all 1 input, door controller 4 could send signal to electronic control unit 5;
The signal of input end receiving gate controller 4, pressure sensor 2, outlet pressure sensor 9 and the inlet pressure sensor 14 of electronic control unit 5, mouth is connected with electromagnetic valve A10, electromagnetic valve B13, air compressor 6, controls respectively the conducting of electromagnetic valve A10, electromagnetic valve B13 and the operation of air compressor 6;
Electric controller 5 is connected with electromagnetic valve A10, electromagnetic valve B13, can control its conducting, with the angle between manual regulation back of seat and seat;
Seat 1 back is equipped with piston rod guide rail 19, and piston rod 17 heads are equipped with sphero-joint 18, the straight-line motion of piston rod 17 can be converted into the rotation of seat 1;
Below in conjunction with accompanying drawing, the utility model specific implementation process is described further.
Under initial condition, human body is P to the pressure of back of seat
k, (be that pressure sensor initial value on backrest is P
k).Electromagnetic valve A, electromagnetic valve B are closed, and cylinder interior air pressure is P
q, make the midway location of piston in cylinder, piston rod sphero-joint is positioned at the midway location of guide rail, take that to keep back of seat and the seat angle between sitting be 110
.Meanwhile, in automobile normal running process, occupant can manual regulation backrest and cushion between angle, by electric controller, control the conducting of electromagnetic valve A, electromagnetic valve B.When electromagnetic valve A conducting, energy storage is to cylinder charge, and angle reduces; When electromagnetic valve B conducting, rely on human body self pressure that the gas of cylinder energy is discharged, angle increases, and meets different occupants' requirement with this process;
When automobile brake, driver steps on brake pedal, and brake pedal sensor receives speed-slackening signal, in real time this signal is passed to door controller; Meanwhile, the variation of the pressure sensor detected pressures on back of seat, when people has motion forward with respect to car, the pressure signal that pressure sensor detects will be zero, if human body does not leave back of seat while braking, the pressure of pressure sensor is by non-vanishing.Now, door controller receives the signal of brake pedal sensor and pressure sensor simultaneously, through controller internal signal, transforms, and whether be all 1 input, if be all 1 input, this energizing signal is passed to electronic control unit if differentiating, otherwise return, continues monitoring.
Electronic control unit receives after the signal of door controller (be automobile brake, and people and car generation relative motion), controls electromagnetic valve A conducting.By energy storage, in cylinder, inflated, promote piston advances forward, and by piston rod sphero-joint, the straight line of piston is converted into the rotation of seat.
At seat and people, keep in homodromous process, the pressure signal that the pressure sensor on back of seat detects is always zero.When it is when this detects pressure signal again, people finishes with respect to car motion forward, starts motion backward.Now, the incoming signal of door controller is to be no longer all 1 input, stop to electronic control unit incoming signal, and then electronic control unit controls electromagnetic valve A and close, and electromagnetic valve B still keeps conducting state.Now, human body relies on the pressure promotion seat that inertia produces to rotate backward, and the gas in cylinder is entered to atmosphere.Work as end of braking, when people and car are relatively stable, the detected pressure of pressure sensor on back of seat returns to initial value P
k, electronic control unit receives signal control electromagnetic valve B and closes.Now, the angle between back of seat and cushion is still not necessarily 100
, occupant can need manual regulation according to self.
By said process, effectively cushioned the impact that automobile brake causes human body, alleviated the vibration that human body is subject in the horizontal direction, improved travelling comfort.
