Bearing circle has north arrow device safe air bag for vehicle driver

The utility model relates to bearing circle and has north arrow device vehicle safety travel chaufeur is being hit or a kind of safety guard of his protection life when colliding with accidental impact certainly.

The air bag that original safe automobile air bag possesses chaufeur and copilot is that mechanical shock is ignited the solid nitrogen inflation; another kind is that electronic striking is ignited miniature gunpowder inflation; and electromechanical also is a powder ignition, though rise driver and copilot has been collided protection, the gunpowder smell and the burn of igniting; because of the compartment narrow and small; vexedly hindered all occupants in the compartment, caused new injury, and once with after just scrap; uneconomical economically, the facial burn easily of the airbag that blended material is made.

A kind of bearing circle has north arrow device safe air bag for vehicle driver; it is to have the north arrow device on the existing bearing circle; aesthetic in appearance; the best viewpoint north arrow of ergonomics device guides the safety traffic of chaufeur correct direction; and it is interior by the high sensitivity impact hammer; locating dowel pin; live and sell mechanical connection on aluminum frame; bump air tube packing spring; the jet gas device; the steel cylinder mechanical connection; during startup and compound inertia high sensitivity bump high-pressure cylinder sensitive diaphragm compressed nitrogen is expanded; airbag becomes air bag; only change steel cylinder after each collision; after debugging, can use again; save precious materials, be a kind of be the not only safe dismounting of economy but also convenient, the most square general novel automobile driver safety fender guard of purposes.

The purpose of this utility model is achieved in that

A kind of bearing circle has north arrow device safe air bag for vehicle driver, the direction machine is spent the strong flange of strong axle and direction disc floret, pad, the nut mechanical connection, it is characterized in that airbag apparatus moulds shell outward and be fastenedly connected by screw and bearing circle, by high sensitivity impact hammer locating dowel pin pin alive mechanical connection on aluminum frame, bump air tube packing spring, the jet gas device, the steel cylinder mechanical connection is solid on the bakelite frame by screw, airbag air drain check valve seal is connected on the gas injection apparatus, hit the sheet brute spring, anchor shaft, latch spring, snap close, hit and transmit bar, security insurance stopper mechanical connection is on aluminum frame, shroud cover is connected air bag and moulds outward on the shell, is connected with the north arrow device for mechanical in the outer circle of bearing circle.

When accident is just hit and the nitrogen of safety guard-safeguard chaufeur and occupant's life when gas is expanded to the compartment in all occupants do not have injury.

Owing to adopt such scheme, simple in structure, easy for installation, interchangeability is good, cost only former airbag apparatus 1/2nd.

The utility model concrete structure is provided by the following drawings:

Fig. 1 is the utility model floor plan scheme drawing.

Fig. 2 is the safety air bag longitudinal sectional drawing of the utility model chaufeur.

Outer circle, 2. air drain screw, 3. gas transmission cell body, 4. brute spring of 1. bearing circle among the figure, 5. anchor shaft, 6. snap close, 7. security insurance stopper, 8. screw, 9. nut, 10. pad, 11. spline flange screws, 12. slip ring seats, 13. the axis of orientation cover, 14. latch springs, 15. airbags, 16. bleeder ports, 17. the gasbag pressure safety disc, 18. hit sheet, 19. boiler check valve, 20. glands, 21. screw, 22. bump pins, 23. seal rings, 24. pull back springs, 25. the jet gas device, 26. transmit bar, 27. bakelite framves, 28. high sense impact hammers, 29. shroud cover, 30. loudspeaker buttons, 31. phosphor-copper contacts, 32. locating dowel pins, 33. binding screw, 34. steel cylinders, 35. steel cylinder diaphragms, the 36. outer shells of moulding, 37. aluminum frame, 38. bearing circle female splines flanges, 39. axis of orientations, 40. connect loudspeaker power slip rings sheet, 41, screw, 42. outer shield, 43. bearing circle, 44 north arrow devices.

Go up detailed description according to the utility model proposes concrete device details and service condition below in conjunction with figure.

When safety air bag is meant positive bump, for the generation of the head that prevents chief and vice driver, in order to reduce the killed degree that causes because of accident with the fatality of chest bearing circle or front glass collision.

Can in 0.025 second, start when being characterized in taking place positive collision accident; airbag opening protection navigating mate; when vehicle takes place by positive the collision; when speed per hour surpasses 35 kilometers/hour; air bag system starts; because the speed of this moment constitutes a threat to the life of chaufeur; different with other safety air bags; because of it does not use gunpowder; misgivings are burnt and ear-drum shatters so even airbag-releasing also need not; it is a kind of NEW TYPE OF COMPOSITE inertia; the high sensitivity sophisticated technology protective value of induction type; even the distribution of automobile and other parts are impaired also has no effect; all cars all can install in 10～20 minutes; its profile has adopted high leather and wooden decorative pattern material; elegant in appearance; adopt 60 liters of special dual its retractilities of texture shape material of high capacity more outstanding; so can minimize by the impulsive force when having an accident; this has given prominence to its safety undoubtedly; can realize re-using of safety air bag with cheap expense; alleviated customer's ability to bear undoubtedly, so its aspect of performance is very remarkable undoubtedly.

Be with the bearing circle 43 female splines flanges 38 of outer circle 1 to be contained on the axis of orientation 39 by nut 9 pads 10; and bearing circle 43 is connected with female splines flange 38 by screw 11 slip ring seat 12 is tightened together; air bag is moulded shell 36 outward and is installed in the bearing circle 43 fastening by screw 8 with outer shield 42; steel cylinder 34 is spun in the jet gas device 25; bump pin 22 pull back springs 24 seal rings 23 are in aggregates; be contained on the bakelite frame 27; be bonded on the gas transmission cell body 3 by super glue by airbag 15; and have boiler check valve 19 outer gland 20 screws 21 fastening backs in aggregates on bakelite frame 27 by screw 2 in the gas transmission cell body 3 with jet gas device 25; there is screw 41 to be installed on the aluminum frame 37 again; brute spring 4 on the aluminum frame 37 twists on the anchor shaft 5 and is pinned by latch spring 14; under 7 protections of security insurance stopper; when installing, transportation is failure to actuate; after being mounted on the automobile; security insurance stopper 7 is thrown away, safe work state when waiting for the contingency collision.

When surpassing 35 kilometers/hour head-on crashs, speed per hour on aluminum frame 37, sells by locating dowel pin 32 work; high sense impact hammer 28; hitting transmission bar 26 makes latch spring 14 press down 6 dislocations of promotion snap close; brute spring 4 jerk strike sheets 18 make bump pin 22 impact steel cylinder 34 upper diaphragms 35 and are crashed through; steel cylinder 34 inner high voltage nitrogen are sprayed to airbag 15 on the jet gas device 25 at top speed; and airbag 15 is washed shroud cover 29 open after expanding at top speed; when the airbag change air bag number of people and chest impact forward owing to inertia; it is disappointing rapidly that pressure makes airbag 15 upper gasbag pressure security sheets 17 break through bleeder port 16; gasbag pressure is reduced, protection head part and chest safety.

And loudspeaker button 30 is pressed by phosphor-copper contact 31 on the bearing circle 43, and binding screw 33 and loudspeaker power slip rings sheet 40 are received under the former bearing circle loudspeaker normal operation on the loudspeaker circuit in the axis of orientation cover 13.

And interior and north arrow device 44 mechanical connections of bearing circle 1 outer circle on the bearing circle 43 are aesthetic in appearance, and the best viewpoint north arrow of ergonomics device guides the safety traffic of chaufeur correct direction.
