In addition, the invention also provides a using method of the buffer backward moving type automobile seat, which comprises the following steps:
after getting on the vehicle, the seat is positioned on the seat, an electromagnetic switch is pressed to control the spherical block to slide back and forth in the electromagnetic slideway, the front and back positions of the seat relative to a steering wheel are adjusted to enable a driver in the front row of the vehicle to be in a comfortable position, the driver backs on the backrest, the backrest is controlled to rotate relatively on the seat by means of thrust generated when the driver leans against the backrest, so that the inclination angle formed by the backrest and the seat is in the most comfortable angle of the driver, a handle is rotated to drive the rotating shaft to rotate relatively in the positioning block, a third torsion spring stores force, the clamping ball slides out of the arc-shaped groove, a fourth compression spring is compressed to slide towards the inside of the clamping groove, the first rotating rod and the second rotating rod rotate relatively, when the clamping ball slides to the next arc-shaped groove, the fourth compression spring resets to push the clamping ball to move outwards, so that the clamping ball is contacted with the arc-shaped groove again for limiting, and the fixing rod, the first rotating rod and, increased stability, because the dead lever is fixed bearing, central line length is less than the sideline forever in the triangle-shaped, when first dwang breaks away from and the lower terminal surface contact of seat, the terminal surface contacts under second dwang and the seat, the control seat uses the contact point of seat and back as the axle center in horizontal space, first half relative slope takes place downwards, driver's shank extension volume has been increased, it is inconvenient because of the short and brake throttle contact of shank to avoid partial driver, make driving safety reduce, the driver can be according to self demand, the handle angle rotates, the control seat is at the inclination of horizontal space, after the use, the reversal handle, the third torsional spring resets, drive the rotation axis reversal, make the screens ball slide the initial position once more, it is spacing with the arc wall contact.
In the initial state, the safety belt is wound on an H-shaped frame and extends out along an outlet at the upper end of the placement cavity through two rollers to pull the safety belt to a proper length, the safety belt is fastened to be tied in front of a body, the safety belt drives the H-shaped frame to rotate in the process of pulling the safety belt, the lug slides out of the limiting groove to slide in the H-shaped frame under the action of centrifugal force, the second compression spring is compressed, the H-shaped frame is driven by the safety belt to move upwards in the placement cavity, when the safety belt stops being pulled, the H-shaped frame moves downwards in the placement cavity due to the self weight of the H-shaped frame, when the lug touches the limiting groove in the downward moving process of the H-shaped frame, the second compression spring resets to push the lug to slide out of the H-shaped frame, the lug contacts with the limiting groove again to lock and limit the H-shaped frame, and because the pulling speed of the safety belt is, the safety belt drives the cylinder and rotates, the lower extreme cylinder drives epaxial reel winding cotton rope, the control axis of rotation takes place to rotate on the connecting rod, the axis of rotation drives the driving lever through the bracing piece and stirs the ratchet and take place relative rotation, first torsion spring holds power, epaxial reel winding cotton rope rotates, slide to "U" type inslot through pulley pulling slider, first compression spring is compressed, because safety belt pulling speed is slower, cylinder slew velocity is less, so the slider slides the distance in "U" type inslot and is limited, make the slider can't break away from the fixed slot, do not produce the influence.
When a large accident occurs, a large impact force is generated instantly, under the action of inertia, the human body tilts forwards instantly when being impacted, the safety belt is pulled instantly to slide out of the placing cavity, and the safety belt slides out instantly. The large pulling force controls the H-shaped frame to rapidly slide out of the placing cavity, the H-shaped frame pulls the guide rod to move upwards, the guide rod drives the trigger plate to compress the third compression spring so as to enable the contact on the placing cavity to be contacted with the contact on the trigger plate, the instant electromagnetic slide way of contact control the spherical block to rapidly move rightwards, the spherical block drives the seat to move rightwards through the positioning block, the first stretching spring is decelerated by the stretching control spherical block in the process of moving rightwards of the spherical block, when the spherical block collides with the buffer plate, the buffer plate drives the buffer block to slide towards the buffer chute, the fifth compression spring is compressed, meanwhile, the buffer plate pushes the piston rods of the two hydraulic cylinders to extrude hydraulic oil in the hydraulic cylinders into the arc-shaped hydraulic cylinders along the oil pipes, the piston rods of the arc-shaped hydraulic cylinders push the wrapping plates to control the wrapping plates to slide out of the arc-shaped hydraulic cylinders to extend into the electromagnetic slide way so, carry on spacingly, the repulsion that produces behind tensile pulling force and the spherical piece striking buffer board that produces of first extension spring to spherical piece production simultaneously cushions spacingly to the device, makes the increase of the interval of seat and car steering wheel, has increased the safe space of striking in-process, has avoided striking in-process driver and steering wheel to collide with, improves the security.
When the safety belt slides out fast, pull the cylinder fast, make the increase of cylinder slew velocity, the lower extreme cylinder passes through the quick winding cotton rope of reel, cotton rope pulling axis of rotation rotates fast on the connecting rod, axis of rotation winding cotton rope passes through pulley pulling slider, control slider slides from the fixed slot, slider compression first compression spring slides to "U" type inslot, make whole control assembly break away from and settle the restriction between the chamber, under the action of gravity, the hole bright subassembly moves down rapidly in settling the intracavity, the axis of rotation fast rotation produces centrifugal force simultaneously, make the driving lever take place relative rotation on the bracing piece, make the driving lever break away from the ratchet, first torsion spring reset control axis of rotation reverses on the connecting rod, the reverse winding cotton rope of reel in the axis of rotation, the quick pulling safety belt is retrieved to settling the intracavity, draw the driver back to lean on the back and.
When meetting great impact force, through whole device for the backward movement of steering wheel and the reverse pulling safety belt of control assembly, pull back the mode of leaning on to fix on the back with the driver, increased driver and steering wheel interval apart from, improved safe space, avoided driver head and the direct striking of steering wheel, cause the secondary injury, retreat of device simultaneously also makes driver shank space increase, when having avoided the automobile to warp, the driver shank is received the extrusion and is caused the injury.
In summary, the invention has the following advantages: this device simple structure, when meetting great impact force, whole device is for steering wheel rearward movement and reverse pulling safety belt, it fixes to pull back the driver and lean on the back, driver and steering wheel interval have been increased, the safety space has been improved, driver's head and the direct striking of steering wheel have been avoided, cause the secondary injury, the retreating of device simultaneously also makes driver shank space increase, when having avoided the automobile to warp, the driver shank is received the extrusion and is caused the injury.
