Abstract
The present invention relates to a kind of automatic buffer seat, for improving the riding comfort of automobile.During automobile brake, people first has motion forward relative to car, can be close to seat with certain speed afterwards, and this process causes impact to human body, adds the sense of discomfort of human body.The present invention passes through brake pedal sensor, chair back pressure sensor, the driving states of automobile and the people motion state relative to car is judged through door controller, electronic control unit is passed in this discriminant information, it is controlled by an electronic control unit the conducting of corresponding magnetic valve, by accumulator, compressed air air is filled with cylinder subsequently, promotion piston movement rotates, and then make seat and people keep moving in the same direction, thus when people is close to seat, pressure produced by human body inertia can be relied on to promote seat to rotate backward, to play cushioning effect.
Description
Technical field
The present invention relates to a kind of automatic buffer seat, riding comfort during for improving automobile brake.
Background technology
When running car is when jolting road surface, occupant can be uncomfortable in the vibration of vertical direction for a long time because of automobile.With
Socioeconomic fast development, the continuous improvement of road traffic, people travel on the road surface jolted the most fewer and fewerily；But
Socioeconomic development simultaneously also makes the recoverable amount of automobile be continuously increased, the carriage way in city the most all the more crowded, for really
Protecting traffic safety, driver need to travel with relatively low speed and it needs to start and stop continually.
Show according to the data that China's " human body bears whole body vibration and evaluates Part I: typically require " announces, people
Body is when vertical vibration, and most sensitive frequency range is 4 ~ 12.5Hz, and when human body vibrates in the horizontal direction, most sensitive
Frequency range is the impact that 0.5 ~ 2Hz, i.e. human body are more vulnerable to horizontal direction vibration.When automobile at the road traveling blocked up or is
When maintaining safe distance and need to slow down, braking can cause people and car constantly to produce relative motion frequently, i.e. people's cognition is by automobile water
The impact of flat vibration, and then easily produce discomfort, what this situation showed when emergency brake, jack rabbit start becomes apparent from.Institute
With, the impact because of relative motion, human body caused when alleviating automobile brake, the riding comfort improving people is had the biggest
Impact.
The safety belt that there is now is primarily to be the safety concerns improving occupant, and it can ensure that automobile exists effectively
Brake hard or relative motion minimum between occupant and car when knocking into the back, it is to avoid occupant comes to harm.And for general driving
Braking, safety belt intelligence can only reduce human body motion amplitude forward to a certain extent, can not improve human body rearward movement
Time suffered impact.

Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Air compressor 6 is connected with air processor 7, and air processor 7 is connected with accumulator 8, and accumulator 8 exports
Place is connected to outlet pressure sensor 9；Accumulator 8 is connected with cylinder 15 air inlet through magnetic valve A10, check valve 11, choke valve 12；
Cylinder 15 import department is connected to air inlet pressure sensor 14；Piston rod 17 contacts with piston rod guide rail 19 through piston rod spherojoint 18；
Cylinder 15 gas outlet is connected with air processor 7 through magnetic valve B13；
Equipped with pressure sensor on seat 1 backrest, to detect whether human body contacts with backrest；On brake pedal equipped with
Brake pedal sensor, to detect whether braking；
Door controller 4 uses and gate control, and according to internal circuit configuration, the pressure signal taking pressure sensor 2 is zero
Time be 1 input, be otherwise 0 input；It is 0 input when being zero during brake pedal sensor 3 brakeless signal, is otherwise 1 input, only
When having two inputs to be all 1 input, door controller 4 could send signal to electronic control unit 5；
The input of electronic control unit 5 receives door controller 4, pressure sensor 2, outlet pressure sensor 9 and enters
The signal of mouth pressure sensor 14, output is connected with magnetic valve A10, magnetic valve B13, air compressor 6, controls electromagnetism respectively
Valve A10, the conducting of magnetic valve B13 and the operation of air compressor 6；
Electronic control unit 5 is connected with magnetic valve A10, magnetic valve B13, can control its conducting, leans on manually regulation seat
Angle between the back of the body and seat；
Seat 1 back is equipped with piston rod guide rail 19, and piston rod 17 head, can be by the straight line of piston rod 17 equipped with spherojoint 18
Conversion of motion is the rotation of seat 1；
Below in conjunction with the accompanying drawings specific implementation process of the present invention is described further.
Under original state, human body is P to the pressure of backrestk, (i.e. pressure sensor initial value on backrest is Pk).
Magnetic valve A, magnetic valve B close, and cylinder interior air pressure is PqSo that piston is in the centre position of cylinder, i.e. piston rod ball connects
Head is positioned at the centre position of guide rail, is 110 ° with the angle between keeping backrest and seat to sit.Meanwhile, at automobile normal running
During, occupant can manually regulate the angle between backrest and cushion, i.e. controls magnetic valve A, electromagnetism by electric controller
The conducting of valve B.When magnetic valve A turns on, accumulator reduces to cylinder charge, angle；When magnetic valve B turns on, rely on human body
The gas of cylinder energy is discharged by pressure itself, and angle increases, and meets the requirement of different occupant with this process；
When automobile brake, driver's brake pedal, brake pedal sensor receives brake signal, in real time by this
Signal passes to door controller；Meanwhile, the change of the pressure sensor detection pressure on backrest, when people has forward relative to car
Motion time, the pressure signal that pressure sensor detects will be zero, if braking time human body do not leave backrest, pressure sensing
The pressure of device will be not zero.Now, door controller receives the signal of brake pedal sensor and pressure sensor simultaneously, through control
Device internal signal processed converts, it determines whether be all 1 input, if being all 1 input, then this triggering signal is passed to Electronic Control list
Unit, otherwise returns and continues monitoring.
After electronic control unit receives the signal of door controller (i.e. automobile brake, and people and car generation relative motion),
Control magnetic valve A conducting.Inflated in cylinder by accumulator, promote piston advances forward, and will be lived by piston rod spherojoint
The straight line of plug is converted into the rotation of seat.
Seat and people keep homodromous during, the pressure signal that the pressure sensor on backrest detects
It is always zero.When this detects pressure signal again for it, people terminates relative to car motion forward, starts rearward movement.Now,
The input signal of door controller is no longer to be all 1 input, stops to electronic control unit input signal, and then electronic control unit
Controlling magnetic valve A to close, magnetic valve B remains on state.Now, human body rely on pressure produced by inertia promote seat to
Rear rotation, enters air by the gas in cylinder.Working as end of braking, people is relative with car when stablizing, and the pressure on backrest passes
Pressure detected by sensor returns to initial value Pk, electronic control unit receives signal and controls magnetic valve B closedown.Now,
Angle between backrest and cushion is the most still 100 °, and occupant can be according to self needing manually regulation.
By said process, effectively buffer the impact that human body is caused by automobile brake, alleviate human body in level
Direction vibrations received, improves riding comfort.
