Description
Technical field
The utility model belongs to automotive safety technical field, especially relates to a kind of safety chair seats of car.
Background technology
In automobile collision accident, the secondary collision occurring between occupant and car inner structure part is the major cause damaging.Although generally there is safety strap and safety air bag in car, in some seats of arranging, safety strap is not usually set after automobile driver seat, only depend on the chair back above to stop.In the time that automobile emergency stops or shock accident occurs, rear row occupant and car inner structure part can bump, and occupant has little time to take self-protection attitude.
Utility model content
For above problem, the utility model provides a kind of safety chair seats of car, and it can, clashing into immediate response before generation, make seat help occupant to complete and curl action, reduces the shock injury that occupant is subject in car as far as possible.
For reaching above object, the utility model is achieved by the following technical solutions.
A kind of safety chair seats of car, it is characterized in that, comprise base, be fixed on the interior chair cushion on base, the outer chair cushion hinged with interior chair cushion, be arranged on the front chair cushion on outer chair cushion, the cylinder and the piston rod that are arranged on outer chair cushion bottom, the gas cylinder being connected by pipeline with cylinder, is arranged on the control cock on gas cylinder connecting line, described piston rod one end is connected with the piston that is arranged on cylinder internal, and the piston rod other end is connected to outer chair cushion below.
The feature of technique scheme and further improvement:
Described outer chair cushion bottom is provided with chute, is provided with the slide bar of chair cushion before connecting in chute; The described piston rod other end is hinged on slide bar below.
Described control cock is electromagnetic gas valve.
Exhaust air entraining device beneficial effect of the present utility model is: single-chip computer control system reacts to control electromagnetic gas valve to the signal of speed measuring module and range finder module; the cylinder that makes to connect gas cylinder drives and on outer chair cushion, turns over and the stretching out of front chair cushion; help occupant to complete in time health and curl action, reduced the shock injury that occupant is subject in the time that automobile emergency stops or collides in car.

Detailed description of the invention
With reference to figure 1, it is a kind of safety chair seats of car of the present utility model, it comprises base (1), on base (1), be fixed with interior chair cushion (2), interior chair cushion (2) is hinged with outer chair cushion (3), is provided with front chair cushion (9) outside on chair cushion (3), chair cushion (3) bottom is provided with cylinder (5) and piston rod (6) outside, cylinder (5) is connected with gas cylinder (7) by pipeline, on gas cylinder (7) connecting line, is provided with control cock (8), and wherein control cock (8) is electromagnetic gas valve.
Wherein, outer chair cushion (3) bottom is provided with chute, and front chair cushion (9) is connected with the slide bar (4) being arranged in chute.Piston rod (6) one end is connected with and is arranged on the inner piston of cylinder (5), and piston rod (6) other end is hinged on slide bar (4) below.
With reference to figure 2, control cock (8) is connected with control system, and control system connects range finder module and speed measuring module.Control system can be selected 51 micro controller systems, and range finder module is optional with photoelectric switch, and speed measuring module can be selected the tachometer circuit of common LM2907 frequency/voltage converter and tachogen composition, and control cock (8) connects relay, and relay is by Single-chip Controlling.When automobile is with object distance is too near above, photoelectric switch is to micro controller system input obstacle distance signal.Meanwhile, the tachogen being positioned on axletree coordinates LM2907 frequency/voltage converter output voltage signal to enter A/D converter, and A/D converter is to micro controller system input speed signal, and micro controller system judges in conjunction with obstacle distance signal and speed signal.If judged result is dangerous, Single-chip Controlling relay, opens control cock (8).
With reference to figure 3; after control cock (8) is opened; gas cylinder (7) stretches out piston rod (6) to the interior inflation of cylinder (5); when stretching out, piston rod (6) promotes to turn on outer chair cushion (3); simultaneously, the slide bar (4) of chair cushion (9) also stretches out under piston rod (6) promotes; the front chair cushion (9) stretching out and the outer chair cushion (3) above turning over lift driver leg, make occupant complete in time health and curl action, and protection occupant reduces clashes into injury.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if these amendments of the present utility model and within modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model also comprises these changes and modification interior.
